Defrost heater protection device of refrigerator
The present invention relates to a defrost heater protection device of the refrigerator, and more particularly, by improving the lower cover fixing the defrost heater so that the defrost heater is smoothly conducted to the lower side to prevent the defrost water remaining in the defrost receiving tray freezes. The present invention relates to a defrost heater protection device of a refrigerator, which is easily drained and easily assembled.
Generally, a defrost heater is a component that is used in a refrigerator, and the temperature rises through a series of heat exchange processes in which a refrigerant generates cold air along a series of cooling cycles, and the generated cold air is supplied to a freezing compartment or a refrigerating compartment, and then cooled inside the refrigerator. The cold air that has been raised to the warmed temperature is returned and returned to the cooler chamber where the evaporator is located. The frost (dew) is generated by the temperature difference between the cold and the returned warm water. Frost (frost) gradually forms on the surface of the evaporator and freezes to form frost. This is an electrical device that periodically checks and removes frost.
Defrost heater is usually fixed to the protection device shown in Figure 1 is installed in the refrigerator, this protection device is provided on the rear side of the portion (hereinafter referred to as "cutting section") that properly partitions the freezer compartment and the refrigerating compartment and its bottom surface The defrosting receiver 10 is formed to be slightly inclined toward the central portion at both ends thereof, and has a drain hole 12 at the central portion thereof, and has a ring-shaped support 14 protruding to a shape and size corresponding to each other on both sides of the bottom surface. And, the upper portion provided on the upper side of the defrost heater 40 to protect the defrost heater 40 from the defrost water from the coating material 20 attached to the bottom surface of the defrost receiver 10 and the evaporator 60 falling down The defrost heater is fitted to the upper cover 50 with the cover 50 and the defrost heater 40 fixed to the support 14 therebetween to hold broken pieces that fall when the defrost heater 40 is damaged. 40, the lower portion provided on the lower side Consists of a member (30)
However, the conventional defrost heater protection device has a problem that the assembly cost is not easy because the number of parts increases the manufacturing cost and the structure is complicated.
Thus, in order to improve this, the applicant has applied for a defrost water protection device as shown in FIG. 2 (Utility Model Registration Application No. 97-2628).
In FIG. 2, the lower cover is removed to reduce the number of parts, and the support 14b for fixing the defrost heater 40 of the defrosting receiver 10b to prevent the upper cover 50b from being easily detached from the protection device during the assembling process. A separate hook 33 is provided on the top surface and the upper cover 50b is fixed to the hook 33.
However, such a protection device has been derived that the support 14b for supporting the defrost heater 40 is easily broken when the defrost heater 40 is forcibly pressurized and fixed in the process of fixing the defrost heater 40.
In addition, since the defrost heater protection device shown in FIG. 2 does not have a lower cover and there is no means for gripping the damaged residue when the defrost heater 40 is damaged, the heating wire connected to the defrost heater 40 is not included. The problem of short-circuit falling on the bottom of the defrosting receiver 10b still remained.
The present invention has been devised to solve the above problems in view of the above-described prior art, and the number of parts is remarkably reduced, so that the structure is simple, easy to assemble, and a defrost heater to allow the thermal shear to occur smoothly under the defrost heater. The purpose is to provide a protective device.
The object of the present invention is to provide a defrost heater protection device of the refrigerator, the heater cover is provided on the defrost heater to protect the defrost heater from falling defrost water, and a pair of insertion holes are formed at both ends, and inserted into the insertion hole of the heater cover. It can be achieved by configuring a pair of supports fixed and bent in a 'b' shape to support the defrost heater from the lower side, and a wire mesh provided between the supports to maintain their spacing.

Hereinafter, with reference to the accompanying drawings with respect to the configuration and effect of the preferred embodiment according to the present invention will be described in more detail.
3 is a perspective view showing only the main portion of the defrost heater 100 protection device according to an embodiment of the present invention, a modification of a conventional lower cover.
Defrost heater protection device according to the embodiment is a heater cover for protecting the defrost heater 100 from defrost water falling toward the defrost heater 100 while the frost is removed from the surface of the evaporator in the same way as the conventional upper heater ( 110 is provided.
Although not shown in the drawing, the heater cover 110 is secured to the inside of the defrosting receiver provided at the rear of the trimmer of the refrigerator.
In addition, a pair of insertion holes 120 are formed at both ends of the heater cover 110.
Here, the heater cover 110 may be formed to be inclined (tapered) to both sides with respect to the center of the long direction to facilitate the drainage of the defrost water.
And, a defrost heater 100 is provided on the lower side adjacent to the heater cover 110, in order to support the defrost heater 100, the support is formed bent in the 'b' shape below the defrost heater 100 ( 130 is provided.
The support 130 includes a wire mesh 150 for maintaining the gap.
The support 130 is a fixed portion 132 is fixed to both ends of the wire mesh 150, the pressing portion 134 is formed to extend outwards on both sides of the fixing portion 132 and the fixing portion ( 132 is extended vertically and the support portion 138 is formed with a ring-shaped fixing groove 170 to fix the defrost heater 100, and a pair formed to be bent at the upper end of the support portion 138 Is composed of a coupling portion (136).
The wire mesh 150 is formed in a network structure in which a plurality of common cross shapes overlap each cell having a rectangular shape.
The wire mesh 150 is pressed by pressing both ends of the wire mesh 150 to the crimping portion 134 using a crimping tool in a state where both ends thereof are placed in the fixing portion 132 of the support 130. 132 is fixed.
In this way, the support 130 to which the wire mesh 150 is fixed inserts coupling portions 136 formed on both ends thereof to the insertion hole 120 of the heater cover 110.
Then, the coupling part 136 is bent to the outside or the inside, respectively, to fix the support 130 provided with the wire mesh 150 to the heater cover 110.
Of course, before fixing the support 130 to the heater cover 110, the defrost heater 100 is already fixed to the fixing groove 170 of the support 130.
Therefore, since the assembly and separation of the defrost heater 100 is easy and the space between the wire meshes 150 is not dense and has a sufficient free space, the defrost heater 100 generated from the defrost heater 100 is lower than the defrost heater 100. Since the defrosting water receiver 10 is smoothly delivered, the remaining defrost water is no longer frozen and drained entirely.
The assembly process is finally completed by fixing the defrost heater assembly in which the assembly is completed in the defrost receiver not shown.
In addition, since the wire mesh 150 is easily oxidized by being combined with oxygen (O ₂ ) and rusted, it is preferable to use a wire mesh formed with an anti-oxidation coating to prevent this, and it is particularly preferable to use stainless steel.
In addition, the anti-oxidation coating is more preferably to prevent corrosion by the defrost water.
As described above, the present invention simplifies the assembly operation by simplifying the conventional defrost heater protection device, which is made of a large number of parts and a complicated structure such as a lower cover, an upper cover, and a support, and reduces the number of parts. It provides an effect that is easy.
Furthermore, since the substructure placed in the defrosting receiver is simple and the inflow and outflow of the defrosting heater is smooth, the bottom surface of the defrosting receiver is not easily frozen, thereby providing an effect of easily draining the defrosting water.
