Detailed Description

The embodiment of the invention provides a fixing device of a fuse wire for a refrigerator. Fig. 1 is a schematic configuration view of a fixing apparatus of a fuse for a refrigerator according to an embodiment of the present invention, as shown in fig. 1, and referring to fig. 2 to 4, the fixing apparatus of a fuse for a refrigerator includes an evaporator and a fusing device 20. The evaporator has fins 10, the fin 10 being typically the outermost one of the fins 10 of the evaporator. The fin 10 is provided with a hanging hole 11 and a clamping hole 12. The fuse device 20 may have a housing 22 and a fuse wire 21 disposed within the housing 22. The housing 22 generally has insulating properties. The housing 22 is provided with a hook 23 and a claw 24. The hook 23 is mounted on the hanging hole 11, and the claw 24 is clamped in the clamping hole 12 after the hook 23 is mounted on the hanging hole 11. That is to say, through installing couple 23 in hanging hole 11, install in hanging hole 11 back at couple 23 in addition, rotate and make jack catch 24 joint in card hole 12, realize the fixed mounting to fuse 21, simple to operate, simple structure can not destroy casing 22, and then can not destroy the insulation protection function of casing 22.

In some embodiments of the present invention, the evaporator may be vertically disposed, and then the fin 10 is preferably vertically disposed, and the hanging hole 11 is located at a lower side of the fastening hole 12. The opening direction of the hook 23 faces downwards, so that the hook 23 is convenient to mount, and the mounting firmness of the hook 23 is ensured after the shell 22 rotates. In some alternative embodiments, the opening direction of the hook 23 may be upward, and the hanging hole 11 may be located at an upper side of the chucking hole 12.

Further, the hook 23 is disposed at the lower end of the housing 22, and includes a first connecting portion 231 extending from the peripheral wall of the housing 22, and a hook portion 232 extending downward from the end of the first connecting portion 231, and the hook portion 232 and the housing 22 are located at two sides of the fin 10. The first connecting portion 231 has a horizontal plate shape, and the hook portion 232 has a vertical plate shape. The hanging hole 11 may be a long hole extending in a horizontal direction.

The claw 24 is disposed at the upper end of the housing 22, and includes a second connecting portion extending from the peripheral wall of the housing 22, and a clamping portion disposed at the end of the second connecting portion, and the clamping portion and the housing 22 are disposed at two sides of the fin 10. Preferably, the second connecting portion includes two symmetrically disposed connecting posts 241 or at least three connecting posts 241 uniformly distributed along a circumferential direction, which are disposed in parallel at intervals. The clamping part comprises a protrusion 242 arranged at the tail end of each connecting column 241; and the protrusion 242 of the distal end of each connection post 241 protrudes in a direction away from the distal ends of the remaining connection posts 241. Through setting up a plurality of spliced poles 241, accessible spliced pole 241 installation time shrink, installation back expansion chucking card hole 12 improves the installation fastness. The chucking holes 12 are circular holes. Of course, other configurations of the jaws 24 may be used.

In some embodiments of the invention, the housing 22 is made of a plastic material, and an epoxy resin is disposed within the housing 22, the epoxy resin encapsulating the fusible link 21. The opening of the housing 22 is directed downward so that the connecting wires of the fusible link 21 protrude from the lower end of the housing 22. Because the fuse wire 21 is further wrapped by the epoxy resin, the fuse wire can be firmly installed in the shell 22, the waterproof performance is high, and the fuse wire 21 is further protected. The opening of the housing 22 is disposed downward, so that water can be prevented from entering the housing 22 through the opening, and water can be prevented from entering the outlet end of the fusible link 21 due to poor sealing.

The embodiment of the invention also provides a method for fixing the fuse wire 21 for the refrigerator, which is fixed by using the fixing device in any embodiment. The fixing method can comprise the following steps: firstly, a hook 23 on a shell 22 of a fusing device 20 is arranged in a hanging hole 11 on a fin 10 of an evaporator; the fuse unit 20 is then rotated and the latch 24 of the housing 22 of the fuse unit 20 is fitted into the latch hole 12 of the fin 10 of the evaporator.
