It consists of a conveying member 46 for conveying the ice to the bad ice storage unit 20 and the standard ice storage unit 30 according to the identified state.
    First, the guide member 42 is installed long in the horizontal direction of the standard ice storage unit 30, and consists of two fragments of which the center portion is open. The two fragments are respectively fixed to the right side wall 32 and the central partition 12 of the standard ice storage unit 30, and each of the fragments is symmetrically facing each other and is bent downward 42a Is formed, the ice iced in the ice maker is placed in the space between the bent surface (42a).

On the other hand, the light emitting unit 44a and the light receiving unit 44b are connected to an external power source and a microcomputer, and the light intensity and intensity of the light are changed as light having a predetermined wavelength emitted from the light emitting unit 44a passes through the ice, thereby receiving the light receiving unit 44b. The microcomputer analyzes the value of the light transmitted by the light receiving unit 44b and identifies it as standard ice and bad ice.
    The carrying member 46 will be described. The conveying member 46 is composed of an ice plate 46a for conveying ice and a driver 46b for driving the ice plate 46a. The ice plate 46a is located in the longitudinal direction at the lower portion of the bent surface 42a of the guide member 42, and has a square shape to support the ice aligned between the inner bent surface 42a of the guide member 42. The plate body is made of a bar shape protruding from one side of the plate body. The rod shape of the ice plate 46a is connected to the driver 46b through a through hole b formed in the side wall 32 of the standard ice storage unit 30. By the power transfer of the driver 46b, the ice plate 46a is formed through the side wall of the bad ice storage unit 20 and the inner partition 12 of the storage container unit. The ice plate passage a and the standard ice storage unit 30 are formed. It is possible to flow up and down and back and forth through the through hole (b) formed in the side wall 32 of the standard ice storage unit 30 or the bad ice storage unit on the ice plate 46a according to the determination of the identification member 44 To 20.
    Next, the present invention will be described in more detail through a process in which standard ice and bad ice are separated through FIG. 5 and FIG. 6 showing the operation of the carrying member 46 of the ice identifying means 40 according to the present invention. .
    First, ice iced by the ice making unit enters the storage container unit 10 installed under the ice making unit. The ice entering the storage container part 10 is aligned between the inner bent surface 42a of the guide member 42, wherein the ice plate 46a of the transport member 46 is closely located below the guide member 42. Accordingly, the ice is placed on the ice plate 46a while being aligned between the bent surface 42a inside the guide member 42.
    When the ice is aligned, the identification member 44 of the ice identification means 40 senses this and emits light having a predetermined wavelength from the light emitting part 44a of the identification member 44 between the bent surface 42a of the guide member 42. It is injected towards the ice aligned in the. The light having a predetermined wavelength passes through the ice and changes its intensity to enter the light-receiving portion 44b, and analyzes the value of the light entering the light-receiving portion 44b to determine that the microcomputer judges the bad ice and the standard ice to take the next operation. do.
    When the above process is explained in more detail, the ice iced in the ice making unit has various shapes according to the ice making process. The standard ice has a normal shape and the inside is formed transparently, whereas the bad ice usually becomes cloudy with the inside. Or cracks inside or have a broken shape without a normal shape.
    When light of a predetermined wavelength is scanned into the shape of each ice, most of the scanned light passes through the standard ice. On the other hand, when the light is injected into the bad ice, the light passes through the ice according to the shape. The light emitted after passing through the ice after being reflected and refracted has a different intensity and intensity than the light passed through the standard ice.
    Since the value before and after the light passes is different according to the shape of each ice as described above, the defective ice and the standard ice are set in the microcomputer through repeated experiment in advance, and the defective ice and the standard ice are judged according to whether the set value is reached. Done.
    In the above judgment, it is not always 100% correctly identified as bad ice and standard ice. That is, as shown, a plurality of ice is placed between the bent surface (42a) of the guide member 42, a variety of the ice may be mixed. As a result, it is sometimes determined that the standard ice is mixed with bad ice, and vice versa. In other words, since one ice is not judged as standard ice and bad ice, the average value is inputted through various experiments in advance, and it is judged as standard ice and bad ice.
    Next, after it is determined as the bad ice and the standard ice as described above, it will be described the process of passing ice to each container.
    First, if it is determined that the standard ice, the driver 46b of the conveying member 46 is operated so that the ice plate 46a is lowered vertically by a certain amount as shown in FIG. 7A, which is a transparency guide. (42) The ice aligned therein can be moved out of the transparency guide 42 so as to be able to move forward and backward. Next, the ice plate 46a moves rearward by a predetermined distance L1 so that the ice placed on the ice plate 46a hits the inner surface of the right side wall 32 of the standard ice storage unit 30 to the inside of the standard ice storage unit 30. Falls.
    In order to more smoothly perform the above process of delivering ice into the standard ice storage unit 30, the ice plate 46a is formed by forming a plurality of protrusions on the side wall 32 of the standard ice storage unit 30 hit by the ice plate ( As 46a) is moved backwards, it may be more easily dropped by hitting the projection formed on the side wall (32).
    After providing the ice into the standard ice storage unit 30, the actuator 46b operates in opposition to the above operation so that the ice plate 46a is again located under the guide member 42.
    In this case, when it is determined that the ice is bad, the ice plate 46a is vertically lowered by a certain amount by the operation of the driver 46b, and then the ice plate 46a is moved forward by a predetermined distance L2 so as to store the storage container 10. It passes through the ice plate passage (a) formed through the partition wall 12 and the side wall of the bad ice storage. Next, the bad ice placed on the ice plate 46a, which is positioned in the bad ice storage unit 20 by the above process, hits the side wall of the bad ice storage unit and falls into the bad ice storage unit 20.
    After the above process is completed, the ice plate 46a is returned to its original position and aligned under the guide member 42. Then, the ice plate 46a is repeatedly performed at the discretion of the identification member 44.
    Next, the entire process of ice making is performed through FIG. 7 showing an ice making flow chart of the ice maker according to the present invention. (The same configuration as in the prior art is shown in FIGS. 1 to 4. A conventional code will be used as it is.)
    First, water is supplied to the ice making container 2a installed in the ice making unit 2 (step 100). The water is supplied through a water source outside the refrigerator, and the adjustment is controlled by a water supply valve located behind the refrigerator compartment. After a certain time (t), the microcomputer (not shown) determines whether the water supply is completed. (Step 200) When the water supply is not completed, the water supply is continued. When the water supply is completed, the water supply is stopped and the ice making unit ( 2) is operated to perform the ice making operation (step 300). After performing the ice making operation for a predetermined time t1 input to the microcomputer (not shown) in advance (step 400), the ice making operation is stopped and the ice making container is stopped ( The ejector 2b located at 2a) is operated (step 500). At this time, the ejector 2b is rotated by 90 degrees and the operation is performed for a predetermined time t2 while the ejector 2b is rotated by 90 degrees. At the same time, the heater (not shown) is heated for a predetermined time (t3) so that the ice formed in the ice making container 2a can be easily separated (step 600). The ice formed in the ice making container 2a by the heater heat. In a state where it can be easily separated from this ice container 2a, Chulgi (2b) and the work is rotated Accordingly ice in the ice tray (2a) has been separated from the ice tray (2a) is to be transferred to the storage container (step 700)
    The transferred ice is arranged in the guide member 42 and placed on the ice plate 46a. Accordingly, the identification member 44 is operated to scan light having a predetermined wavelength from the light emitting unit 44a and pass through the ice. Light enters the light receiving unit 44b. (Step 800) The microcomputer determines the information input to the light receiving unit 44b to determine whether it is standard ice or bad ice.
    When it is determined that the standard ice according to the above determination, power is transmitted to the driver 46b of the carrying unit 46, and the ice plate 46a is operated to transfer the ice to the standard ice storage unit 30. )
    If it is determined by the discriminator 44 that the ice is bad, the ice plate 46a is operated in accordance with the determination to transmit the bad ice to the bad ice storage unit 20 (step 1000). The unit 46 returns to its original state and is turned off (step 1100).
    After the above process is performed, water is supplied to the ice making unit again to repeat the above process.
    The ice maker structure according to the present invention described above has the following advantages.
    Ice iced from the ice making unit is divided into defective ice and standard ice by means of ice identification, so that users can always obtain standard ice, which increases the satisfaction and reliability of the product. Therefore, the ice in the container can be used for other purposes according to the user's intention.
