The multiple groups of ice crushing teeth 42 are fixedly installed on the ice crushing bars 41. The ice crushing bars 41 are fixedly installed directly below the condensing coil assembly 6. The ice crushing assembly 4 is located directly below the condensing coil assembly 6. When the top heating assembly 7 is running, the ice on the condensing coil assembly 6 will fall onto the ice crushing assembly 4. The ice crushing teeth 42 can effectively crush these ice cubes and speed up the defrosting speed. The design of the ice crushing assembly 4 is simple.

[0042] Embodiment 6, based on embodiment 5, combined with Figure 6 To explain:

[0043] The top heating assembly 7 includes: a heating tube 71, a heating tube fixing block 72 and a top plate 73. The heating tube 71 is provided with multiple groups. The multiple groups of heating tubes 71 are fixedly installed on the lower side of the top plate 73 through the heating tube fixing block 72. Both sides of the top plate 73 are fixedly connected to the third connecting portion 24. The multiple groups of heating tubes 71 are distributed on the lower side of the top plate 73, which can provide uniform heat distribution, ensure that the frost on the condensing coil assembly 6 can be melted evenly, and avoid local overheating or underheating. The heating tube 71 is made of metal material and has good thermal conductivity. It can quickly transfer heat to the condensing coil assembly 6, thereby achieving rapid defrosting. The heating tube fixing block 72 is used to fix the heating tube 71, which can ensure that the heating tube will not move or fall off during operation, ensuring the stability of the structure. The top plate 73 can play a certain role in heat insulation, preventing heat from dissipating upward, thereby improving thermal efficiency and reducing energy waste.

[0044] The working principle of the utility model is as follows: when the utility model is in use, the various components are fixedly connected by screws and bolts. When the condensing coil assembly 6 needs to be defrosted after being used for a long time, the top heating assembly 7 is started to heat the condensing coil assembly 6 to melt the ice cubes attached to the condensing coil assembly 6. The melted ice cubes fall onto the ice crushing assembly 4 under the action of gravity and are cut and dispersed, thereby accelerating the ice melting efficiency. The melted ice water is discharged through the water outlet pipe 33, thereby saving manpower. The utility model can independently control the top heating assembly to heat by setting the top heating assembly 7, thereby enhancing the defrosting effect. The ice cubes on the condensing coil assembly 6 can fall onto the ice crushing assembly 4, thereby increasing the melting speed of the ice cubes and thus improving the defrosting efficiency. The melted ice water can be collected by setting the water collecting tray assembly 3 to prevent it from contaminating other components. The support assembly 5 can provide good support for the condensing coil assembly 6, thereby facilitating the setting of the condensing coil assembly 6 close to the top heating assembly 7, thereby improving the ice melting efficiency.
