As shown in fig. 7, a slope 64 extending obliquely toward the power feeding device 2 is formed inside the protection case 6 corresponding to the open end 41 of the protection cover 4. When the side face of the electrical contact 1 is matched with the abutting face 42 to push the opening end 41 to open the protective cover 4, the end face of the electrical contact 1 extends out to abut against the inclined face 64 of the protective box 6, along with the sliding installation of the tray 101, the side face of the electrical contact 1 continues to push the protective cover 4, the end face of the electrical contact 1 abuts against and slides along the inclined face 64, when the tray 101 slides to a specified position, the end face of the electrical contact 1 abuts against and slides to the power supply device 2 along the inclined face 64 to abut against the power supply device 2, so that power supply is achieved, the inclined face 64 is favorable for guiding the electrical contact 1 to slide to a position corresponding to the power supply device 2, in addition, when the tray 101 is disassembled, the electrical contact 1 can slowly retract along the inclined face 64, and the tray 101 is more convenient for a user to disassemble and assemble and disassemble the tray 101.

In the embodiment, the protection box 6 and the protection cover 4 are enclosed to form a box body for covering the power supply device 2, so that the power supply device 2 can be further protected, dust or insects can be prevented from entering the box body, and the sliding groove 65 is arranged at the opening 66 of the protection box 6, so that when the tray 101 is not installed, the protection box 6 is a basically closed box body, the service life of the power supply device 2 can be prolonged, and the safety risk can be reduced; further, by providing the inclined surface 64 extending toward the power feeding device 2 at a position of the protective case 6 corresponding to the opening end 41 of the protective cover 4, the electrical contact 1 can be guided to enter or exit a position abutting against the power feeding device 2 in accordance with the sliding of the tray 101, and the user can easily attach and detach the tray 101.

In another embodiment of the present invention, there is provided a refrigerator including a refrigerator main body and a tray 101 detachably attached to the refrigerator main body, and further including the fixed power supply mechanism in any one of the above embodiments. Since a large amount of water vapor often condenses in the chamber 100 of the refrigerator, the safety risk such as short circuit caused by the water vapor condensing on the power supply device 2 can be further reduced by using the fixed power supply mechanism in the embodiment.

It will be appreciated by those of ordinary skill in the art that in the embodiments described above, numerous technical details are set forth in order to provide a better understanding of the present application. However, the technical solutions claimed in the claims of the present application can be basically implemented without these technical details and various changes and modifications based on the above-described embodiments. Accordingly, in actual practice, various changes in form and detail may be made to the above-described embodiments without departing from the spirit and scope of the utility model.
