Technical Field

[0001] The utility model relates to the technical field of freezers, in particular to a freezer with adjustable space. Background Art

[0002] A freezer is a facility that uses various equipment to cool, can be controlled artificially, and maintains a stable low temperature. The refrigeration system, control device, insulated warehouse, and auxiliary buildings are the basic components of a cold storage. The refrigeration system of a cold storage mainly includes a cold storage unit, which is the core of the cold storage and ensures the cold source supply in the cold storage warehouse. The control device is the brain of the cold storage. It directs the refrigeration system to ensure the supply of cold capacity. It maintains a certain low temperature indoors through artificial refrigeration. The walls, floors, and flat roofs of the cold storage building are paved with a certain thickness of thermal insulation materials to reduce heat transfer from the outside of the cold storage.

When there are fewer goods, the entire space inside the freezer still needs to be refrigerated, which results in a large energy loss. At the same time, the temperature inside the freezer is low, and the inner wall is prone to ice formation, which will affect the refrigeration effect. The top height of the freezer is high, and deicing is difficult. In order to solve the above problems, this application proposes a freezer with adjustable space. Utility Model Content

[0029] It should be noted that the sealing frame 8 can seal the connection between the lifting cover 5 and the lifting slot 6, which can reduce the outflow of cold in the freezer. When the inner cavity of the freezer needs to be expanded, by controlling the extension of the No. 1 hydraulic rod 7, the No. 1 hydraulic rod 7 will push the lifting roof 4 to lift, which can realize the rapid expansion of the freezer and is more flexible to use.

[0030] In this embodiment, if Figure 2 and Figure 3 As shown, a sealing frame 8 is provided in the inner cavity of the lifting groove 6, the inner wall and outer wall of the lifting cover 5 are in contact with the inner wall of the sealing frame 8, a corresponding hole is penetrated through the bottom of the inner cavity of the sealing frame 8 corresponding to the position of the No. 1 hydraulic rod 7, and the piston rod of the No. 1 hydraulic rod 7 penetrates the corresponding hole.

[0031] It should be noted that the No. 1 hydraulic rod 7 can push the lift roof 4 to move up and down.

[0032] In this embodiment, if Figure 2 and Figure 4 As shown, a frost protection cover 9 is integrally formed on the lower surface of the lifting warehouse roof 4, the outer wall of the frost protection cover 9 is in contact with the inner wall of the wall 2, and a shovel head 10 is provided at the bottom edge of the frost protection cover 9.

[0033] It should be noted that after the lifting warehouse roof 4 is raised, the position between the lifting warehouse roof 4 and the top of the wall 2 is shielded by the anti-frost cover 9, so that ice is formed on the surface of the anti-frost cover 9, which can avoid icing on the surface of the lifting cover 5, and the lifting warehouse roof 4 can shovel away the ice on the top of the inner wall of the wall 2 through the shovel head 10 when it is lowered.

When the inner cavity of the freezer needs to be expanded, the No. 1 hydraulic rod 7 is controlled to extend, and the No. 1 hydraulic rod 7 will push the lifting roof 4 to lift, which can realize the rapid expansion of the freezer, and the use is more flexible. After the lifting roof 4 is raised, the position between the lifting roof 4 and the top of the wall 2 is blocked by the anti-frost cover 9, so that ice is formed on the surface of the anti-frost cover 9, which can avoid the icing phenomenon on the surface of the lifting cover 5, and the lifting roof 4 can be lifted by the shovel head 1 when it is lowered. 0 Shovel away the ice on the top of the inner wall of the wall 2 to ensure the flexibility of the lifting and lowering of the lifting warehouse roof 4. A large amount of ice on the inner wall of the freezer will affect the refrigeration effect of the refrigeration system. The ice on the lifting warehouse roof 4 should not be scraped quickly. By controlling the No. 2 hydraulic rod 15 to push the middle part of the top plate 11, the telescopic rod 14 will drive the moving seat 13 to move in the moving groove 12. At the same time, the telescopic rod 14 will be pulled out from the moving seat 13. At this time, the middle part of the lower surface of the top plate 11 is convex. By deforming the top plate 11, the ice layer formed on the surface of the top plate 11 can be quickly broken, so that the top of the freezer can be quickly de-iced.
