[0002] The main function of the defrosting device for a cold storage is to remove frost and ice inside the cold storage to ensure the normal operation of the equipment and extend its service life. Specifically, the defrosting device removes frost and ice inside the cold storage through different methods (such as blowing air, heating, etc.) to prevent equipment failures and increased energy consumption caused by the accumulation of frost.

[0003] The prior art publication number CN220582868U discloses a defrosting device for a cold storage, belonging to the field of defrosting technology, including a base. On the outer wall of the top of the base, two opposite vertical support frames are installed by bolts. Between the two vertical support frames, two opposite rotating frames are provided. On the outer wall of one side of a vertical support frame, a motor one is installed by bolts. The output shaft of the motor one is connected to a rotating shaft through a coupling, and the end of the rotating shaft far from the motor one is arranged on the outer wall of one side of the other vertical support frame.

[0059] Based on the defrosting device of a cold storage in Embodiment 1 and its working principle of the cold storage are as follows:

[0060] First, when in use, hold the telescopic frame 5 by hand and push the device into the working area of the cold storage. Then, pull out the collection box 3. By turning on the electric push rod 4, the support plate 7 is pushed to move upward. The first gear 14 is driven to rotate through the notch B 8, driving the worm 13 to drive the worm gear 12 to drive the bidirectional screw 11 to rotate. While driving the slider 10 to move, the telescopic support 15 is relatively driven to expand and contract;

[0061] Second, simultaneously drive the second C-shaped plate 16 and the first C-shaped plate 17 to move, so that the first connecting plate 27, the second connecting plate 28, and the T-shaped heat conduction plate 32 are in contact with the frost surface. At the same time, turn on the small electric push rod 25 to pull the second slider 20 to move, pull the first slider 19 to move through the connecting belt 24, and at the same time, the tension spring 26 is stretched;

[0062] Third, when the first slider 19 and the second slider 20 move, drive the small gear 21 to rotate through the notch A18. At the same time, drive the limit post 22 to rotate through the connecting post. Relatively, drive the first connecting plate 27 to move reciprocally through the limit port 29. At the same time, while the friction plate 31 and the T-shaped heat conduction plate 32 slide relative to each other, heat is generated by friction. Transfer the heat to the T-shaped heat conduction plate 32 so that while it is in contact with the frost surface, the frost absorbs heat and melts. At the same time, the conical protrusions provided on the outer side of the first connecting plate 27 can also scrape off the frost at the upper and lower ends of the first connecting plate 27 and the second connecting plate 28, so that it falls into the collection box 3 and can also be collected.

[0063] Through improvement, the present invention provides a defrosting device for a cold storage and the cold storage. When in use, turn on the electric push rod 4 to drive the support plate 7 to move, and at the same time, the telescopic support 15 is telescopically unfolded. Drive the T-shaped heat conduction plate 32 to contact the frost surface through the second C-shaped plate 16 and the first C-shaped plate 17. At the same time, turn on the small electric push rod 25 to drive the second slider 20 and the first slider 19 to move. At the same time, engage with the small gear 21 through the notch A18, relatively drive the first connecting plate 27 and the second connecting plate 28 to move reciprocally, and at the same time drive the friction plate 31 and the T-shaped heat conduction plate 32 to generate heat by friction, increase the temperature of the T-shaped heat conduction plate 32, and transfer the heat to the frost surface while in contact with the ice surface to melt it, so that defrosting can be carried out.
