[0027] A circulation pipe 13 is fixedly connected to the inner wall of the top of the water tank 1, the rotating plate 9 and the gear 1 10 are both rotatably mounted on the top of the water tank 1 through a rotating column, the motor 12 is fixedly mounted on the top of the water tank 1, and the bottom end of the rotating shaft of the motor 12 is fixedly connected to the top of the gear 2 11, both ends of the circulation pipe 13 are arranged inside the water tank 1, and a heat conduction box 14 is fixedly mounted outside the circulation pipe 13, and a heater 16 is fixedly mounted inside the water tank 1;

[0028] The motor 12 drives the movable shaft 8 to repeatedly push and pull the piston 7, so that the melted water inside the refrigerator is sucked into the water tank 1. At the same time, the water tank 1 is pressurized so that the heated water circulates in the circulation pipe 13. Then, two heat conduction boxes 14 are placed on different layers of the refrigerator to quickly heat and melt the frost, thereby facilitating the improvement of the defrosting efficiency of the refrigerator. At the same time, the melted accumulated water is directly absorbed into the device, thereby avoiding manual wiping of the cabinet body, reducing the defrosting steps, and increasing the practicality of the refrigerator defrosting device.

[0029] Both ends of the circulation pipe 13 are arranged inside the water tank 1, and the bottom end surface of the water outlet end is flush with the top inner wall of the water tank 1, and the bottom end surface of the water inlet end is flush with the inner bottom wall of the water tank 1, so that it is convenient to circulate the water inside the water tank 1 into the circulation pipe 13. At the same time, since the heat conduction box 14 is made of heat-conducting metal material, it is convenient to heat the heat conduction box 14 and then melt the frost inside the cabinet;

[0030] Example 2:

[0031] Based on Example 1, in order to facilitate the storage and use of the device, please refer to Figure 1 , Figure 4 and Figure 5 The pumping cylinder 4 is provided with water flow holes at positions corresponding to the one-way valve 1 3 and the one-way valve 2 5, and the one-way valve 1 3 includes a sealing gasket 31, which is fitted on one side of the water flow hole, and a fixing strip 32 is fixedly connected inside the water flow hole, a spring 33 is fixedly connected to one side of the fixing strip 32, and a moving column 34 is fixedly connected to one end of the spring 33;

[0032] The movable column 34 is movably arranged inside the fixed strip 32, and one end of the movable column 34 is fixedly connected to one side of the sealing pad 31. The sealing pad 31 and the movable column 34 are elastically installed with the fixed strip 32 through the spring 33. The middle part of the circulation pipe 13 is a mosquito coil-like structure, and the middle part of the circulation pipe 13 is fixedly installed inside the heat conduction box 14. The top of the water tank 1 is symmetrically installed with a placement box 15, and handles 17 are rotatably installed on both sides of the water tank 1. One side of the water tank 1 is pressure-connected with a water plug 18;

[0033] The used heat conduction box 14 is placed inside the placement box 15, and then the circulation pipe 13 is bent and stored. The entire device can be directly lifted and placed by the handle 17, so that the refrigerator defrosting device is convenient to carry and use, and the water inside the water tank 1 can be drained through the water plug 18;

[0034] When the water tank 1 is placed on its side, water can be added to the water tank 1 through the water port at the water plug 18, which is convenient for replacing the water in the water tank 1, thereby preventing the water tank 1 from absorbing accumulated water and causing odor, and preventing the inner wall of the water tank 1 from being corroded and damaged, thereby ensuring the long-term use of the defrosting device for the refrigerator;

[0035] Since the one-way valve 1 3 and the one-way valve 2 5 have the same internal structure and are oppositely arranged, when the sealing gasket 31 of the one-way valve 1 3 is sucked into the water pump 4 to open the water flow hole, the sealing gasket 31 of the one-way valve 2 5 is sucked and fits to block the water flow hole, thereby facilitating the control of the accumulated water entering the water tank 1. At the same time, when the amount of accumulated water is not large, air will be sucked into the water pump 4, and after the air enters the water tank 1, it will also play a pressurizing role, thereby facilitating the liquid to enter the circulation pipe 13 for use.

[0036] Working principle: When using the refrigerator defrosting device, turn off the power of the refrigerator and take out the food, then hold the handle 17 and place the device at the bottom of the refrigerator, so that the bottom end of the water suction pipe 2 contacts the inner bottom wall of the refrigerator, and then place the two heat conduction boxes 14 on different layers above, and then the heater 16 heats the water inside the water tank 1, and then the motor 12 drives the gear 2 11 and the gear 1 10 to rotate, so that the rotating plate 9 drives the movable shaft 8 to move, and then the piston 7 is repeatedly pushed and pulled inside the water pump 4;

[0037] When the piston 7 moves toward the outside of the water pumping cylinder 4, the sealing gasket 31 is moved toward the inside of the water pumping cylinder 4 by suction, so that the corresponding water flow hole inside the one-way valve 1 3 is opened, thereby generating suction force on the water suction pipe 2, so that the melted water flowing to the bottom of the refrigerator is sucked into the water pumping cylinder 4. When the piston 7 is pushed toward the inside of the water pumping cylinder 4, the sealing gasket 31 inside the one-way valve 2 5 is flushed open, and then the water inside the water pumping cylinder 4 enters the water delivery pipe 6 through the water flow hole on one side of the one-way valve 2 5;

[0038] Then it enters the water tank 1, and after the gas-liquid mixture enters the water tank 1, the water tank 1 is pressurized, so that the water in the water tank 1 flows into the circulation pipe 13, and then the heated water circulates in the circulation pipe 13, and then the heat conduction box 14 is heated, so that the inside of the refrigerator is quickly heated, and then the frost inside the refrigerator is conveniently melted, thereby completing the defrosting operation.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
