Description

Technical Field

[0001] This utility model relates to the field of defrosting technology, and in particular to a heatable defrosting shovel. Background Technology

[0002] After prolonged use, the inner walls of refrigerators and freezers will continuously come into contact with moisture in the air, which will then condense and accumulate as frost. This frost layer will severely affect the cooling efficiency of the refrigerator and freezer and increase energy consumption, so regular defrosting is necessary.

[0003] To improve defrosting efficiency, some defrost scrapers have a heating plate or heating wire at the scraper head. For example, CN209840507U discloses a refrigerator defrost scraper with a heating element. This scraper is suitable for removing thin ice from the surface of the inner liner. When the frost layer is thick, it is usually necessary to break the frost layer by force first. However, metal defrost scrapers can easily scratch the inner liner while breaking the ice. In addition, the scraper head of a heated defrost scraper is usually made of aluminum. Because aluminum has poor strength, it cannot be used to break the ice layer by striking it; it is only suitable for removing thin ice from the surface of the inner liner. Utility Model Content

[0020] like Figures 1-3 As shown, this utility model provides a heatable defrosting shovel, including a shovel head 1 and a shovel handle 2. The bottom of the shovel head 1 is provided with a slide rail 11, and a heating element 3 is provided in the slide rail 11. The heating element 3 slides along the slide rail 11, and the position of the heating element 3 can be adjusted according to the usage state of the defrosting shovel. The heating element 3 can extend from the bottom of the shovel head 1 or be retracted.

[0021] The scraper head 1 and the scraper handle 2 are made of high-temperature resistant PP material. The front end of the scraper head 1 has scraper teeth 12 that facilitate cutting into the frost layer, increasing the friction with the frost layer and improving defrosting efficiency. When defrosting, the scraper head 1 can be forcefully scraped into the frost layer to break it up. The PP material has low hardness and will not scratch the surface of the inner liner.

[0022] The shovel handle 2 is equipped with a power compartment 21, which contains a rechargeable power source. The bottom of the shovel head 1 is provided with a slide rail 11, within which a heating element 3 is installed that can slide back and forth along its length. The heating element 3 includes an outer shell and heating elements disposed within the outer shell. The heating element 3 moves back and forth along the slide rail 11, extending or retracting from the bottom of the shovel head 1.

[0023] The rear end of the shovel head 1 is provided with a groove that is aligned with the slide rail 11. An installation plate 7 is provided at the opening of the groove. A sliding groove 71 is provided in the installation plate 7. The installation plate 7 and the groove form an adjustment cavity 4. An adjustment switch 5 is provided in the adjustment cavity 4. The adjustment switch 5 is slidably connected in the adjustment cavity 4. The position of the heating element 3 is adjusted by sliding the adjustment switch 5 along the sliding groove 71.

[0024] The position adjustment switch 5 is a spring-loaded pin, including a handle 51, a plunger 52, an upper housing 53, and a spring 55. The handle 51 and the plunger 52 are coaxially arranged and threaded together. A limiting piece 54 is fixedly provided on the side wall of the plunger 52. The upper housing 53 is sleeved on the outer periphery of the plunger 52 and has a cavity. The spring 55 is sleeved on the outer periphery of the plunger 52 and placed in the cavity.

At this time, the position adjustment switch 5 can be moved back and forth along the slide groove 71 to adjust the position of the heating element 3. After it is moved into place, it is reinserted into the slot under the elastic force of the spring 55.

[0027] Furthermore, wire storage troughs are provided on both sides of the adjustment cavity 4, and high-temperature resistant spiral wires are installed in the wire storage troughs. One end of the spiral wire is connected to the heating element 3, and the other end is connected to the battery compartment via a switch. Using spiral wires to connect the power supply and the heating element 3 can be used to address changes in the distance between the heating element 5 and the power supply caused by the movement of the heating element 5.

[0028] When using the device, to remove a thicker layer of frost, the heating element 3 can be retracted, and the scraper teeth 12 can be used to scrape off the frost. When removing the frost on the inner liner surface, pull the handle 51. The handle 51 drives the plunger 52 out of the first slot 41 and moves the adjustment switch 5 forward along the slide groove 71 to the second slot 42. Under the elastic force of the spring 55, it automatically inserts into the second slot 42. The adjustment switch 5 drives the heating element 3 to move to the outside of the scraper head 1. Turn on the switch to start the heating element 5. The frost on the inner liner surface melts quickly under heating, which can effectively remove the thin ice on the inner liner surface.
