    Technical Field
    The present invention relates to an ice making device. More specifically, the present invention relates to an ice making device that is installed in a refrigerator to make ice pieces in the refrigerator and to take the manufactured ice pieces to an ice storage container in the refrigerator. Foundations
    Conventionally, a refrigerator such as a household refrigerator is known, which is provided with an ice-making function in which pieces of ice are manufactured and the manufactured ice pieces are supplied to an ice storage container for storing ice pieces. and that is arranged inside the refrigerator.
    As this type of ice-making device, for example, an ice-making device described in Patent Literature 1 and 20 is similar. More specifically, as shown in Figure 8 (a), an ice-making device 60 is provided which is provided with an ice tray 61 for the manufacture of ice pieces, a rotary drive component 62 which rotates the ice tray. ice 61 to make 25 pieces of manufactured ice fall from the ice tray 61 and a frame body 63 to which the ice tray 61 and the rotary drive component 62 are attached. List of References Patent Literature [PTL 1] Japanese patent published No. 2001-165538. Summary of the Invention Technical problem
    In the ice-making device 60 shown in Figure 8 (a), to fix the ice tray 61 and the rotating drive component 62 to the frame body 63, the following method can be devised. That is, as shown in Figure 8 (b), an end 61a of a rotating bar of the ice tray 61 is inserted into a perforating hole 63a of the frame body 63 and an end 61a of the rotating bar is supported by the frame body 63 Then, while the other end 61b of the rotating bar of the ice tray 61 is fitted to an output shaft 62a of the rotary drive component 62, a locking piece 62b of the rotary drive component 62 is inserted into a part retaining part 63b of the frame body 63. In this case, the retaining part 62b is deformed to be inserted into the retaining part of the tongue part 63b. However, it is difficult to make the fixing tongue part 62b and the fixing part of the tongue part 63b have sufficient strength to be able to resist deformation resistance.
    On the other hand, a method could be devised, for example, in which the output shaft 62a of the rotary drive component 62 is fitted to the other end 61b of the rotating bar of the ice tray 61, at the same time as the component is made. rotary drive 62 slide in the direction of arrow "A" in Figure 8 (a) (direction of output shaft 62a of rotary drive component 62). However in this case, it is necessary, for example, the following change in the project. In other words, a wall component located on an external side in the direction of the output shaft 62a of the rotary drive component 62 is removed, or the frame body 63 is extended to the external side to produce a space so that the rotary drive component 62 is able to slide. When the wall component located on the outside in the direction of the output shaft 62a of the rotary drive component 62 is removed, the resistance of the frame body 63 is reduced and thus this change in design is difficult. Alternatively, when a space in which the rotary drive component 62 is able to slide is provided, after the output shaft 62a has been fitted to the other end 61b, a dead space is formed on the outside of the rotary drive component 62 in the direction of arrow "D" and thus the size of the icing device 60 in the direction of the output shaft 62a of the rotary drive component 62 is unnecessarily increased.
    An object of the present invention is to propose an ice-making device whose mounting properties are improved by preventing the formation of unnecessary space that occurs when mounting is carried out. Solution of the problem
    In this type of an ice making device, an ice detector element is used to detect the insufficiency of pieces of ice stored inside an ice storage container in which the pieces of manufactured ice are stored and thus, the inventors of the present invention considered that an unnecessary space, which is used when conducting the assembly, is used as a space for fixing the ice detection element and, therefore, the present invention is completed.
    In other words, the ice making device according to the present invention includes an ice tray, a drive component which is provided with an outlet shaft to which the ice tray is attached and to which the ice tray is attached. it is turned by turning the output shaft, and a frame body to which the drive component is connected. In the ice making device, a twisting operation is applied to the ice tray during the operation of rotating the ice tray to separate the pieces of ice from the ice tray. The drive component is provided with a fastening part on the drive side which is able to fit a fastening part on the side of the frame body to secure the drive component to the frame body inside the frame body and the drive component is attached to the frame body by the fact that the mounting part on the side of the frame body and the fixing part on the drive side are connected together in a direction that is perpendicular to the output shaft.
    In this case, it is preferable that when the drive component has to be attached to the frame body, the drive component is moved along the direction that is perpendicular to the output shaft, a space is formed between the drive component and the 30 frame body on a rear side in a direction of travel of the drive component when the drive component has been moved along the direction, and a rear side in the direction of travel of the drive component that faces the space that is fixed with an ice detection element to detect a quantity of pieces of ice inside the ice storage container which is arranged on a lower side of the ice tray.
    In addition, it is desirable for the ice detection element to be fitted to an ice detection bar to rotate the ice detection element which is arranged on a rear side in the direction of travel of the drive component, along the direction which is perpendicular to the output shaft, and the distance from which the ice detection element is moved when the ice detection element is fitted to the ice detection bar is less than the distance from which the drive component is moved when the drive component is attached to the frame body.
    In addition, it is desirable for one end of a rotating bar of the ice tray to be supported by the frame body, for the other end of the rotating bar to be fitted to the output shaft of the drive component so that the drive rotary drive is capable of being transmitted, that the ice tray is twisted due to the fact that a part protruding for the twist provided on one end side of the ice tray abuts against a back part provided on the frame body, which hinders the rotating movement of the ice tray, and that a direction of travel of the drive component, when the drive component is attached to the frame body, is the same direction as the direction of the force transmitted to the attachment side fixing part through the 5 output shaft of the drive component and from the ice tray against the twist applied to the ice tray.
    Furthermore, it is desirable that the fastening part of the drive side is designed in the form of a tongue piece protruding from the drive component, that the fastening part of the side of the frame body is designed in the form of a part for inserting the tongue into which the tongue piece is inserted, and that an area of a first abutment face of the part for inserting the tongue that leans against the tongue piece and is welded with a force 15 in a vertical direction transmitted from the tongue piece through the output shaft of the drive component and coming from the ice tray against the twist applied to the ice tray is greater than an area of a second back face of the part for inserting the tongue 2 0 abuts the tongue piece and is arranged in a position where it interposes the tongue piece together with the first abutment face.
    Furthermore, it is desirable that the reinforcement ridge which reinforces the part for inserting the tongue is provided on the first side of the face of the part for inserting the tongue.
    In addition, it is desirable that the first abutment face and the second abutment face do not overlap each other in the direction perpendicular to the outlet axis in the direction perpendicular to a direction of attachment of the drive member. Advantageous Effects of the Invention
    According to the ice-making device according to the present invention, the drive member is fixed to the frame body using the feature of making the fastening part next to the frame body of the body the frame and the fastening part of the drive side of the drive component are adjusted to each other along the direction perpendicular to the drive shaft output shaft, thus not creating a dead space in the direction of the drive shaft exit shaft . Therefore, the creation of unnecessary space at the time of assembly is prevented, and the assembly property is improved.
    In this case, a space is provided due to the fact that the drive component is fixed in the direction perpendicular to the output axis of the drive component. However, the space is used as a space for fixing the ice detection element. Therefore, the occurrence of unnecessary space at the time of assembly is prevented, thereby improving the assembly property.
    In this case, the ice detection element is adjusted and fixed on the rear side in the direction of travel of the drive component along the direction that is perpendicular to the output shaft and, when the distance of movement of the ice detection element is greater. adjustment time is adjusted to be less than the travel distance of the drive component 30 when the drive component is adjusted and fixed to the frame body, the space in the (horizontal) direction perpendicular to the output shaft that is used to fix the drive component can be used as a displacement space to secure the ice detection element. Therefore, the creation of unnecessary space at the time of assembly is prevented, thus improving the assembly property.
    In addition, in a case where the direction of travel of the drive component when the drive component is attached to the frame body is set to be the same direction as the direction of the force that is transmitted to the fastening part on the drive side through the output shaft of the drive component and from the ice tray against the torsional force applied to the ice tray, disengagement of the drive component from the frame body is prevented by the force acting on the drive component due to the operation of twisting of the ice tray. Therefore, even when the ice tray is twisted, the drive component is securely attached.
    In addition, in a case where the fastening part on the drive side is designed in the form of a tongue piece and the fastening part on the side of the frame body is designed in the form of a part for inserting the tongue in which the tongue piece is inserted, when an area of a first face of the part for inserting the tongue that leans against the tongue piece and is received with a force in a vertical direction transmitted to the tongue piece through the axis output of the drive component from the ice tray against the twist applied to the ice tray is greater than an area of a second face of the part for the insertion of the tongue that abuts the tongue piece and that is arranged in a position that interposes with the first face the tongue piece, a face to which the force is applied is adjusted to be greater and thus the holding force for the driving component is increased.
    In addition, in this case, where a reinforcement ridge that reinforces the part for the insertion of the tongue is provided on the side of the first abutment face, the resistance of the face where the force is applied is improved, with the retention for the drive component.
    In addition, when the first abutment face and the second abutment face do not overlap in the direction perpendicular to the output shaft and in the direction perpendicular to the direction of attachment of the drive component, the part for inserting the tongue is designed without use a slip core as a matrix for molding 20 resin.

    In the following, an embodiment of the present invention will be described in detail. As shown in Figure 1, an ice making device 1 according to an embodiment of the present invention is provided with an ice tray 2, a drive component 3 to which the ice tray 2 is attached and through which the tray of ice 2 is rotated, a frame body 4 to which the drive component 3 is attached and an ice detector element 5 which is attached to the drive component 3 to detect a quantity of pieces of ice stored in a storage container ice not shown, in which the pieces of ice produced are stored. The ice-making device 1 shown in Figure 1 is seen from the bottom.
    The ice tray 2 is designed having a rectangular shape and is provided with a multiplicity of recessed parts to which water is supplied from a water supply component not shown for the storage of water and the manufacture of pieces of ice. The steel tray 2 includes a rotating bar 22 along a longitudinal direction and can be rotated together with the rotating bar 22 as a center of rotation. A projecting portion 23 is rotated to rotate around the rotating bar 22, the ice tray 2 rotating around the rotating bar 22.
    The ice tray 2 is formed of resin material or the like, which is elastically deformable and such that, when a torsional force is applied around the rotating bar 22, the ice tray 2 is capable of being deformed. The other end of the rotating bar 22 of the ice tray 2 is formed with an adjustment groove not shown which is able to fit the output shaft 32 of the drive component 3. In this embodiment, a thermistor 24 for detecting the temperature of the ice tray 2 is attached to the bottom of ice tray 2.
    The drive component 3 to which the ice tray 2 is attached includes, as shown in Figure 2, a motor not shown which is a drive source, a rotation transmission mechanism not shown for transmitting a rotation force from the motor and cam gear, not shown, to which the rotating force of the motor is transmitted through the rotating transmission mechanism in a rectangular case 31 which is formed having a parallelepiped shape. The rotating transmission mechanism is designed in the form of a worm gear and a gear train, not shown, and the rotational force of the engine is transmitted to the gear train via the worm gear that is connected to the engine.
    The cam gear inside the drive component 3 is designed as an integral part of the output shaft 32 with which the other end of the rotating bar 22 of the ice tray 2 is connected to transmit the rotational force of the motor to the ice tray 2. The output bar 32 projects to an external side of the case 31 having a hole provided in a wide opening face 31a on one side of the case 31. The output shaft 32 is rotatable by the motor rotation force that is transmitted to the cam gear via the rotation transmission mechanism. The output shaft 32 is rotated in a clockwise direction (turning to the right, in the direction of the "R" arrow) when the pieces of ice have to be separated from the ice tray 2 and, when the ice tray 2 has been rotated for the separation operation, has to be returned to the original position, the output shaft 32 is rotated in a counterclockwise direction (turning left, in the direction of the arrow "L").
    In addition, an ice detection mechanism which is operated by the cam gear is provided within the case 31 of the drive component 3. The ice detection mechanism includes a detection bar lever, which is operated by a cam face. on a rotating central side of an annular shaped recessed part, not shown, which is formed on one face of the cam gear, an ice detection bar 33 which transmits the movement of the ice detection bar lever to a ice detection element 5, and a helical spring, not shown, that applies a force to swing the ice detection bar 33. The ice detection bar 33 projects towards the outside of the case 31 from 10 from a hole provided in a side face 31b on one side of the case 31. The ice detection bar 33 is rotated by turning the cam gear. The ice detection bar 33 is rotated in a counterclockwise direction (turning to the left, in the direction of the "L" arrow), when an ice detection operation is conducted, and when returned to its original position, the ice detection bar 33 is rotated in a clockwise direction (rotated to the right, in the direction of the "R" arrow).
    Two tongue pieces 34a and 34b consisting of 20 fastening parts on the drive side for fastening the drive component 3 to the frame body 4 are formed to protrude in a direction of projection of the output shaft 32 from the face of wide opening 31a of the case 31 from which the output shaft 32 protrudes. The tongue pieces 34a and 34b are formed on an upper side of the drive component 3 which is fixed to the frame body 4.
    As shown in Figure 3, the frame body 4 to which the drive component 3 is attached is designed having a rectangular shape, in order to surround in all directions with side walls and in such a way that its upper face and its bottom face are opened. A side wall 41a on one end side in a longitudinal direction is formed having an insertion hole 42 into which an end 22a of the rotating bar 22 of the ice tray 2 is inserted to pivotally support the ice tray 2. The hole insert 42 is provided with an internal diameter slightly larger than the outer diameter of an end 22a of the rotating bar 22 of the ice tray 2, and an end 22a of the rotating bar 22 of the ice tray 2 is adjusted loosely in the insertion hole 42. In addition, the side wall 41a is provided with a stop part 43, with which the protruding part 23 for twisting provided on one end side in the longitudinal direction of the ice tray 2 abuts when the tray ice 2 is rotated so that it protrudes from the side wall 41a towards an internal side direction of the frame body 4.
    In a side wall 41b on the other end side in the longitudinal direction of the frame body 4, a part of an upper face is closed with a top plate 44 and the drive component 3 is fixed to the top plate 44. The top plate top 44 is formed to correspond to the size of the drive component 3 with parts for inserting the tongue 45a and 45b which are fastening parts on the side of the frame body for fastening the driving component 3 and into which the tongue pieces 34a and 34b of the drive member 3 can be inserted, and a compression part 46 to compress the drive member 3 such that the drive member 3 attached to the frame body 4 does not move.
    Figure 4 is a perspective view in cross section showing a state in which the drive component 3 has been fixed to the frame body 4 and is cut in a vertical direction along a face that includes the parts for inserting the tongue 45a and 45b to explain a state in which the tongue pieces 34a and 34b of the drive component 3 are inserted into the parts for inserting the tongue 45a and 45b of the frame body 4. As shown in Figure 4, the parts for insertion latches 45a and 45b are designed in the form of latch inserts 451a and 451b that project having a hook shape of the top plate 44 to an internal side in a vertical direction of the frame body 4, and abutment faces on the side of the top plate 4 52a and 452b which must rest against the tongue parts 34a and 34b of the drive component 3. The tongue insert parts 451a and 451b are provided with abutment faces on the side of the insert part 453a and 453b which leans m to the tongue parts 34a and 34b of the drive component 3 and the tongue parts 34a and 34b of the drive component 3 are inserted between the abutment faces on the side of the insert 453a and 453b and the abutment faces on the side of the top plate 452a and 452b.
    Two parts for the tongue insert 45a and 45b are provided according to the number of tongue parts 34a and 34b of the drive component 3. Each of the parts for the tongue insert 45a and 45b is molded as an integral part of the plate top 44 using matrices designed to be separated from each other in the upper and lower direction without using a sliding core5. The tongue inserts 451a and 451b and the top plate 44 are designed so as not to overlap each other in the upper and lower direction. Each of the parts for the tongue insert 45a and 45b is opened in the same direction along a horizontal direction that is perpendicular to the output shaft 32 of the drive component 3 which is attached to the frame body 4 (in Figure 4, the parts for tongue insert 45a and 45b are opened to the left in the horizontal direction).
    In each of the parts for the tongue insert 45a and 45b, its opening direction is associated with the direction of rotation of the output shaft 32 of the drive component 3 which is fixed to the frame body 4. In other words, when a face from which the output shaft 32 protrudes is seen as a front face, each of the parts for the tongue insert 45a and 45b is open, so that the drive component 3 is moved (slid) in a direction opposite to the direction of rotation of the output shaft 32 to rotate the ice tray 2 when an ice separation operation from the manufactured ice pieces is to be conducted. More specifically, as shown in figure 4, the direction of rotation of the output shaft 32 is a clockwise direction (rotation to the right, direction of the arrow "R") and, on an upper side of the drive component 3 where tongue pieces 34a and 34b are provided, the output shaft 32 is rotated from right to left. As the left sides of the tongue insert parts 45a and 45b of the frame body 4 are open and, when tongue parts 34a and 34b are to be inserted into the tongue insert parts 45a and 45b, the drive component 3 is moved from left to right in the horizontal direction perpendicular to the output axis 32 of the drive component 3. The positions in the horizontal direction of the inserted tongue parts 34a and 34b are determined by the tongue insert parts 451a and 451b.
    One of the two parts for inserting tongue 45a and 45b (first part of inserting tongue 45a) is provided on a front side of the direction of travel of the driving component 3 (right side in Figure 4) is in the vicinity of a wall side of the frame body 4. On the other hand, the other part for inserting the tongue (second part for inserting the tongue 45b) is provided on a rear side in the direction of travel of the driving component 3 (left side in Figure 4 ) and on an inner side in the horizontal direction of the frame body 4, by a length of displacement of the drive component in relation to a side wall of the frame body 4.
    In the first part for the tongue insert 45a which is arranged on the front side in the direction of travel of the drive component 3, an area of the back face on the side of the insert 453a (a first back face) is designed to be larger than an area of the stop face on the side of the top plate 4 52a (a second stop face). In the second part for the tongue insert 45b which is arranged on the back side in the direction of travel of the drive component 3, an area of the back face on the side of the top plate 452b (a first back face) is designed to be greater than an area of the abutment face on the side of the insert 453b (a second abutment face). In addition, the tongue insert 451a of the first part for tongue insert 45a is formed with a reinforcement ridge 47 on a face opposite the abutment side of the insert part 453a and the tongue insert 451a the first part for the tongue insert 45a is reinforced by the reinforcement ridge 47.
    The lengths "11" and "12" of the abutment faces on the side of the insert 4 53a and 4 53b in the parts for inserting the tongue 45a and 45b in the direction of travel of the drive component 3 are insertion lengths of the parts of tab 34a and 34b which are inserted into the parts for inserting tab 45a and 45b. The insertion length "12" in the second part for the tongue insert 45b is adjusted to be shorter, so that the tongue part 34b of the drive component 3 engages with the tongue insert 451b of the second part for insertion tongue 45b only to prevent the tongue piece 34b from coming off. On the other hand, the insertion length "11" in the first part for inserting the tongue 45a (length "11" of the back face on the side of the insert 453a of the first part for inserting the tongue 45a in the direction of the movement of the drive component 3) is designed to be longer than the length "12" of the back face on the side of the insert 453b of the second part for inserting the tongue 45b in the direction of travel of the drive component 3 to provide a greater holding force than the force to prevent the tongue piece 34a from coming off.
    The compression part 46 of the frame body 4, as shown in Figure 3, is projected from a cut piece that is formed by cutting a part of the top plate 44 along the direction of travel of the driving component 3 which is connected to the frame body 4. The compression part 46 is elastically deformable (deflectable and deformable) in a direction perpendicular to the face of the top plate 44. One side of the cut end piece is formed into a folded piece that is folded in a direction towards the inside of the frame body 4 which is perpendicular to the top plate 44 and a tip end of the folded part is folded back in the direction of movement of the drive component 3 which is fixed to the frame body 4. A compression part 46 is arranged on the rear side in the direction of travel of the drive component 3 attached to the frame body 4 and the side face 31b of the rear side in the direction of travel of the drive component 3 can be retained by the folded piece.
    As shown in Figure 5, the ice detection element 5 attached to the drive component 3 is designed from an ice detection bar fixing part 51 which is fixed to the ice detection bar 33 which is formed so such that it protrudes horizontally from the face of the case side 31b on the rear side in the direction of the movement of the drive component 3, an ice detection part 52 which is arranged on the underside of the ice tray 2 for driving of an ice detection operation in which the ice detection part 52 leans against the pieces of ice inside the container for the storage of ice, not shown, where pieces of manufactured ice are stored, and to a connection part 53 connecting the fixing part of the ice detection bar 51 to the ice detection part 52. The ice detection element 5 is formed having an arm shape. The rotary movement of the ice detection bar 33 is transmitted to the ice detection element 5 through the ice detection bar fixing part 51. Therefore, when an ice detection operation is conducted, the ice detection part 52 is rotated in a counterclockwise direction (rotating to the left) around the attachment portion of the ice detection bar 51 and is moved downward. In addition, when the ice detection part 52 is returned to the original position, the ice detection part 52 is moved upward by rotating the ice detection part 52 clockwise (right rotation) around the fixing the ice detection bar 51.
    An assembly method for the ice making device 1 will be described below.
    First, an end 22a of the rotating bar 22 of the ice tray 2 is inserted into the insertion hole 42 provided in the side wall 41a on one end side in the longitudinal direction of the frame body 4. Then the drive component 3 is fixed to the frame body 4, while the output shaft 32 of the drive component 3 is fitted within the adjustment groove, not shown, which is formed at the other end of the rotating bar 22 of the ice tray 2. Thus, at a end 22a of the rotating bar 22 of the ice tray 2 is pivotally supported by the frame body 4 and the other end 22b is fitted to the output shaft 32 of the drive member, so that the pivoting motion can be transmitted.
    In this case, one end 22a of the swivel bar 22 of the ice tray 2 is loosely fitted to the insertion hole 42 of the side wall 41a of the frame body 4. Therefore, the other end of the swivel bar 22 of the ice tray 2 is arranged on the rear side in the direction of displacement of the driving component 3 with respect to an end 22a of the swivel bar 22 and, in a state where the ice tray 2 is arranged in such a way that the swivel bar 22 of the swivel tray ice 2 is slightly inclined in a direction along the longitudinal direction of the frame body 4, while the other end of the rotating bar 22 of the ice tray is fitted to the output shaft 32 of the drive component 3, as shown in Figure 6 (a), the tongue pieces 34a and 34b of the drive component 3 are positioned but open ends of the parts for the tongue insert 45a and 45b of the frame body 4.
    Then, as can be seen in Figure 6 (b), the compression part 46 of the frame body 4 is compressed by the main body of the drive member 3 so that the compression part 46 is resiliently folded. In this state, as shown in Figure 6 (c), the drive component 3 is moved (slid) from the left side to the right side in the horizontal direction perpendicular to the output shaft 32 of the drive component 3 and the parts of tongue 34a and 34b of drive member 3 are inserted into the parts for inserting fingers 45a and 45b of the frame body 4.
    Simultaneously with the insertion of the tongue pieces 34a and 34b of the drive component 3, the other end of the rotating bar 22 of the ice tray 2 is also moved from left to right in the horizontal direction perpendicular to the output shaft 32 of the drive component 3 and thus the ice tray 2 is arranged in a direction parallel to the longitudinal direction of the frame body 4. When the tongue parts 34a and 34b of the drive component 3 are inserted into the inner portions of the parts for tongue inserts 45a and 45b of the frame body 4, the driving component 3 passes through the folded part of the compression part 46 and thus the compression part 46 which has been resiliently folded is returned to its original position. In this way, the side face 31b of the rear side in the direction of travel of the drive member is supported by the folded part of the compression part 46.
    Then, the ice detection element 5 is attached to the ice detection bar 33 of the drive component 3. When the drive component 3 is attached to the frame body 4, as shown in figure 5, a space "C" is provided between the side face 31b on the rear side in the direction of travel of the driving component 3 and the side wall portion of the frame body 4. The ice detection bar 33 projects from the side face of the case 31b facing the space "C" on the rear side in the direction of travel of the drive component 3. The ice detection element 5 is fixed in the "C" space using the "C" space. More specifically, the attachment part of the ice detection bar 51 of the ice detection element 5 and the ice detection bar33 of the drive component 3 are adjusted to each other along the horizontal direction perpendicular to the outlet axis 32 of the drive component 3. In this case, as the ice detection element 5 is moved in the right direction, the adjustment direction coincides with the direction in which the tongue parts 34a and 34b of the drive component 3 are inserted into the parts for the tongue insert 45a and 45b of the frame body 4. A travel distance "13" of the ice detection element 5 at the time of adjustment is less than the travel distance "11" of the drive component 3 when the component drive 3 is fixed.
    In the following, an operation of the ice-making device 1 will be described below.
    Firstly, the pieces of ice are made in the ice tray 2. More specifically, water is supplied from a water supply part not shown to the ice tray 2, which is arranged horizontally and the water supplied to the ice tray 2 is frozen by a cooling part not shown which is arranged on an upper side of the ice tray 2. Whether the pieces of ice have been manufactured or it is not judged whether the thermistor 24 attached to the bottom of the ice tray 2 detects a temperature predetermined temperature or a temperature below it.
    When the ice making operation has been completed, a number of pieces of ice inside the ice storage container are arranged on a lower side of the ice tray 2 is detected by the ice detection element 5. More specifically, the ice detection element 5 is rotated around the ice detection bar fixing part 51 by rotating the ice detection bar 33 of the drive component 3 and the ice detection part 52 of the ice detection element ice 5 is shifted down. When the defrost detection part 52 is moved down to a predetermined position, it is considered that the pieces of ice inside the ice storage container are not enough. On the other hand, when the ice detection part 52 leans against the ice pieces inside the ice storage container before moving to the predetermined position, the ice pieces inside the ice storage container are considered there are enough of them.
    When the pieces of ice inside the ice storage container are sufficient in number, after having waited for a predetermined period of time, an amount of pieces of ice inside the ice storage container is again detected by the ice element. ice detection 5. The detection operation for a quantity of ice pieces by the ice detection element 5 is carried out repeatedly for a predetermined waiting period until the ice pieces within the ice storage container are considered to be there are not enough of them.
    When the pieces of ice inside the ice storage container are not enough (ie the pieces of ice inside the ice storage container are insufficient), an operation of separating ice from the pieces of ice is carried out. links made in the ice tray 2. More specifically, the ice tray 2 connected with the output shaft 32 is rotated by rotating the output shaft 32 of the drive component 3. When the ice tray 2 is turned from one predetermined rotation angle of 90 degrees or more (120 degrees, for example) from the first position where the ice tray 2 is horizontally arranged, the protruding part 23 for twisting the ice tray 2 abuts the back part 43 of the body frame 4. In this state, further rotation of the ice tray 2 is prevented and the ice tray 2 is twisted together with the rotating bar 22 of the ice tray 2 as its center of torsion. Therefore, the ice tray 2 is deformed by twisting. In this mode, the pieces of ice in the ice tray 2 are separated from the ice tray 2 to be thrown into the ice storage container that is arranged on the underside of the ice tray 2. The fact of the ice pieces in the ice tray 2 have been separated from the ice tray 2 or it is not evaluated, for example, by the fact that the ice tray 2 has been rotated from a predetermined rotation angle (of 160 degrees, for example) that is greater than the rotation angle at which the protruding part 23 for the twisting of the ice tray 2 abutted the abutment part 43 of the frame body 4. Whether the ice tray 2 has been rotated to a predetermined angle of rotation or is not detected , for example, using the cam gear of drive component 3.
    After it has been detected that the ice tray 2 has been rotated to a predetermined rotation angle (of 160 degrees, for example), in which the pieces of ice in the ice tray 2 are considered to have separated from the ice tray 2, the ice tray 2 is inverted to be returned to the first horizontal position. Then water is supplied again to the ice tray 2 of the water supply pair, not shown, and pieces of ice will be manufactured in the ice tray 2. According to an embodiment of the present invention, before inverting the water tray ice 2, the ice tray 2 can be immobilized for a predetermined period of time at the predetermined rotation angle at which the pieces of ice are considered to have been separated from the ice tray 2.
    According to the fact that the ice-making device 1 has the structure mentioned above, the tongue insert parts 45a and 45b which are side fastening parts of the frame body of the frame body 4 and the tongue parts 34a and 34b which are fastening parts on the drive side of the drive component 3 are fitted (inserted) to each other along the (horizontal) direction that is perpendicular to the output shaft 32 of the drive component 3 and thus the drive component drive 3 is fixed to the frame body 4. Therefore, a dead space is not formed in the direction of the output shaft 32 of the drive component 3. In this case, although a space is provided, due to the fastening of the drive component in the direction ( horizontal) perpendicular to the output shaft 32 of the drive component 3, the space is used as a fixing space for the ice detection element 5. Therefore, unnecessary space is prevented at the time of assembly and the yes, the assembly property is improved. The ice detection element 5 is adjusted and fixed on the rear side in the direction of travel of the drive component 3 along the direction (horizontal I is perpendicular to the output shaft 32. The travel distance "13" of the ice detection element ice 5 at the time of adjustment is set to be less than the travel distance "11" of the drive component 3 when the drive component 3 is adjusted and attached to the frame body 4. Therefore, the space in the (horizontal) direction perpendicular to the output shaft 32 which is used to fix the drive component 3 can be used as a displacement space to fix the ice detection element 5. Therefore, unnecessary space is prevented from occurring at the time of assembly and is thus assembly property improved.
    In addition, in the ice separation operation of the ice making device 1, as shown in Figure 7, the output shaft 32 is rotated clockwise (rotation to the right, in the direction of the "R" arrow) when the output shaft 32 of the drive component 3 is viewed from the front. When the ice tray 2 connected with the output shaft 322 is rotated by rotating the output shaft 32, the protruding part 23 for twisting the ice tray 2 abuts the stop part 43 of the frame body 4. In this state, when the ice tray 2 is further rotated, a torsional force is applied to the ice tray 2 and the ice tray 2 is twisted. The twisted ice tray 2 is applied with a force that will return the twisted ice tray 2 to a state prior to twisting, in a direction opposite to the previous direction of rotation and this force is transmitted to the output shaft 32. Therefore the component drive 3 is applied with the force that will reverse the rotation in the opposite direction to the previous rotation direction of the ice tray 2 (direction counterclockwise, direction of the arrow "L"). Consequently, the tongue insert part 45a of the frame body 4 into which the tongue part 34a of the drive component 3 is inserted is welded with a force directed to an upper right direction from the tongue part 34a of the component drive 3, and the tongue insert part 45b into which tongue part 34b is inserted is welded with a force directed to the lower right direction from tongue part 34b. In other words, when the ice tray 2 is twisted, the parts for the tongue insert 45a and 45b of the frame body 4 are received with forces in the right direction from the tongue parts 34a and 34b of the drive member 3.
    In the ice making device 1 of this embodiment, the tongue pieces 34a and 34b of the drive component 3 are inserted into the parts for inserting the fingers 45a and 45b of the frame body 4 in the right direction. In other words, the tongue parts 34a and 34b of the drive component 3 are inserted into the parts for inserting tongue 45a and 45b of the frame body 4 along the directions of the forces in which the parts for inserting tongue 45a and 45b from the frame body 4 are received from the tongue parts 34a and 34b of the drive component 3 when the ice tray 2 is twisted. In addition, the positions of the tongue pieces 34a and 34b in the horizontal direction are prevented by the tongue insert parts 451a and 451b. In other words, the direction of travel of the drive component 3 when the drive component 3 is attached to the frame body 4 is adjusted to be in the same direction as the direction of the force in the horizontal direction that is transmitted to the parts for the insertion of tongue 45a and 45b through the output shaft 32 of the drive component 3 from the ice tray 2 against the twist applied to the ice tray 2. Therefore, the force in the horizontal direction that acts on the drive component 3 that is going to reverse the rotation of the driving component 3 with the twisting operation of the ice tray 2 is supported by the tongue insert parts 451a and 451b, thus avoiding disengagement of the driving component 3 from the frame body 4. Consequently, even when the ice tray 2 is twisted, the drive component 3 is fixed securely.
    In addition, in the ice separation operation of the ice making device 1, as shown in figure 7 at the time of the twisting operation of the ice tray 2, when a force that will reverse the rotation in the opposite direction to the direction of rotation of the ice ice tray 2 (counterclockwise, arrow direction "L") acts on the drive component 3, the first part for inserting the tongue 4 5a of the frame body 4 into which the tongue part 34a of the drive 3 is inserted and welded with the force coming from the tongue piece 34a of the drive component 3 in the upper right direction. On the other hand, the second part for inserting the tongue 45b of the frame body 4 is received with the force coming from the tongue piece 34b of the driving component 3 in the lower right direction. Therefore, the abutment face on the side of the insert 453a of the first part for the tongue insert 45a is received with a force in the vertical direction which is transmitted to the tongue piece 34a through the output shaft 32 of the drive component 3 of the ice tray 2 against the twist applied to the ice tray 2, and the back face on the side of the top plate 452b of the second part for the tongue insert 45b is received with a force in the vertical direction which is transmitted to the piece of tongue 34b.
    In this embodiment, the tongue insert parts 451a and 451b and the top plate 44 are designed so as not to overlap each other in the upper and lower direction for the convenience of the dies. In this case, in the first part for the tongue insert 45a, the area of the back face on the side of the insert 453a (first face of the back) is designed to be larger than the area of the back face on the side of the plate top 452a (second back face). In other words, in the first part for the tongue insert 45a, the area of the back face on the side of the insert 453a to which the force is applied at the time of the twisting operation of the ice tray 2 (first back face) is adjusted to be larger. On the other hand, in the second part for the tongue insert 45b, the area of the back face on the side of the top plate 452b (first face of the back) is designed to be larger than the area of the face on the side of the part insert 453b (second abutment face). In other words, in the second part for inserting tongue 45b, the area of the back face on the side of the top plate 4 52b to which a force is applied when twisting the ice tray 2 (first back face) ) is adjusted to be larger. In this way, since the tongue parts 34a and 34b of the drive component 3 are retained with greater intensity, the holding force of the drive component 3 is greater. In addition, the tongue insert 451a to which a force is applied during the twisting operation of the ice tray 2 is reinforced by the reinforcement ridge 47 and thus increases the holding force of the driving component 3.
    In this embodiment, on the occasion of a twisting operation of the ice tray 2, in a second part for the insertion of the tongue 4b, a force acting on the back face of the side of the insert 453b is less than the force that acts on the stop face on the side of the top plate 452b which will reverse the rotation of the drive component 3. Therefore, the insertion length "12" of the tongue piece 34b for the second part for the tongue insert 45b may have its length adjusted in such a way that it is prevented from exits of the tongue piece 34b.
    Although the present invention has been shown and described, with reference to specific modalities, several changes and modifications will be apparent to those skilled in the art based on the instructions in this document.
    In the embodiment described above, for example, to fix the drive component 3 to the frame body 4, tongue parts 34a and 34b are provided in the drive component 3 and the parts for inserting tongues 45a and 45b into which they are inserted the tongue pieces 34a and 34b are provided in the frame body 4 and the tongue pieces 34a and 34b of the drive component 3 are inserted in the parts for inserting the fingers 45a and 45b of the frame body along the horizontal direction ) perpendicular to the output shaft 32 of the drive component 3. However, a structure can be adopted in which the tongue pieces are provided in the frame body 4 and the parts for inserting the tongues having opening parts in which the pieces tabs of the frame body 4 are able to be inserted and provided in the drive component 3 and the tongue parts of the frame body 4 are inserted into the parts for inserting tabs of the drive component to 3 along a (horizontal) direction perpendicular to the output shaft 32 of the drive component 3.
    In addition, in the embodiment described above, to secure the drive component 3 to the frame body 4, the drive component 3 is moved to the right. However, this direction corresponds to the direction of rotation of the drive component 3 for the conduct of the ice separation operation and thus, when the direction of rotation of the drive component 3 for the conduct of the separation operation is set to be in the opposite direction. , the direction of travel of the drive component 3 must be set to the left.
