Thawing device and refrigerator

Abstract

The application discloses a thawing device and a refrigerator. The thawing device comprises a heating device, which is installed on the bottom surface of the thawing drawer; a tray, which is arranged in the thawing drawer and is provided with a plurality of rotatable ball wheels, the top of the ball wheel is in contact with the food to be thawed, the bottom of the ball wheel is in contact with the thawing drawer, and the bottom of the ball wheel is heated by the thawing device; and a driving device, which drives the tray to repeatedly move in the thawing drawer, the ball wheel rotates, and the contact surface with the bottom surface of the thawing drawer is changed. According to the application, the tray with the ball wheels is arranged in the thawing drawer, the tray is driven by the driving device to have the same vibration frequency as the refrigerator compressor, the tray is displaced, the heating device is arranged on the bottom surface of the thawing drawer, the ball wheels are heated, the heat is transmitted to the food to be thawed through the rotation of the ball wheels, and the thawing speed of the food to be thawed is accelerated.

Claims

1. A thawing apparatus, characterized by, include: The heating element is installed flush against the bottom surface of the outside of the defrosting drawer; A tray is placed inside the defrosting drawer. The tray is equipped with multiple rotatable ball wheels. The top of the ball wheels contacts the food to be defrosted, and the bottom contacts the defrosting drawer. The bottom of the ball wheels is heated by the defrosting device. A driving device drives the tray to move repeatedly inside the defrost drawer, with the ball wheels rotating to change the contact surface with the bottom of the defrost drawer, while the food moves on the tray. The driving device includes: Multiple elastic elements, one end of which is connected to the front outer wall of the tray, and the other end of which is connected to the front inner wall of the defrost drawer; A sling, one end of which is connected to the rear outer wall of the tray, and the other end is equipped with a gravity hammer. The end with the gravity hammer passes through the defrost drawer and is suspended in the compressor cavity. A switch assembly is disposed inside the compressor cavity and corresponds to the gravity hammer. When the switch assembly is turned on, it connects with the gravity hammer and transmits the vibration of the compressor to the gravity hammer, which in turn causes the tray to move.

2. The thawing apparatus of claim 1, wherein The tray is provided with multiple mounting through holes, and the ball wheel is rotatably installed in the mounting through holes.

3. The thawing apparatus of claim 1, wherein The switching assembly includes: Multiple second springs are evenly distributed on the base of the compressor; An electromagnetic plate is mounted on the second spring. When the electromagnetic plate is energized, the gravity hammer is attracted to the electromagnetic plate, and the vibration of the compressor is amplified and transmitted to the gravity hammer through the second spring. When the electromagnetic plate is de-energized, the gravity hammer and the electromagnetic plate separate.

4. The defrosting device as described in claim 1, characterized in that, The drive device also includes a pulley disposed on the rear side of the defrosting drawer.

5. The defrosting device as described in claim 1, characterized in that, The elastic element is a spring.

6. The defrosting apparatus as described in claim 5, characterized in that, Hook holes are provided on the front and rear outer walls of the tray, and the spring and the sling are attached to the tray.

7. The defrosting apparatus as described in claim 1, characterized in that, The heating device is installed on the bottom surface of the defrosting chamber and is in contact with the bottom surface of the defrosting drawer.

8. A refrigerator, characterized in that, Includes the defrosting device as described in any one of claims 1-7.

9. The refrigerator as described in claim 8, characterized in that, The refrigerator includes: an outer shell and an inner liner disposed within the outer shell, a foam layer is provided between the outer shell and the inner liner, and sleeves are vertically spaced within the foam layer, with two slings of the drive device passing through the sleeves and extending into the compressor cavity.
