Cold storage and refrigeration device and drawer assembly thereof

Abstract

The invention relates to a cold storage and refrigeration device and a drawer assembly thereof. The drawer assembly comprises a seal bucket with an opening in the front end, a tray and a drawer; the seal bucket comprises a bucket body and a bucket cover, the tray is arranged to be inserted into the bottom of the seal bucket through the opening in the front end in a push and pull manner, the draweris borne on the tray, and is arranged to be inserted into the seal bucket in a push and pull manner along with the tray, and the drawer is provided with a drawer body and a front end plate arranged on the front side of the drawer body. The tray is located on the head of the outer side of the seal bucket when the drawer is in the completely closed state, the head of the tray and the drawer are inair tight seal through a seal part, the head of the tray and the front end of a bottom plate of the seal bucket are in air tight seal through a seal part, the front end plate and the front end of thebucket cover of the seal bucket are in air tight seal through a seal part, and the bucket body and the bucket cover are in air tight seal through a seal part, so that when the drawer is in the complete closing state, a sealed storage space is formed in the drawer. Manufacturing, maintaining or replacing and the like of all parts is facilitated, seal with the good effect and the higher level can beformed in the drawer.

Description

technical field [0001] The invention relates to refrigeration equipment, in particular to a refrigeration and freezing device and a drawer assembly thereof. Background technique [0002] In order to meet the high-quality requirements of users, existing refrigerators and other refrigerating and freezing devices are usually equipped with airtight storage spaces to avoid odor collusion between the storage space and other compartments in the refrigerating and freezing devices. There are many ways to form the storage space. One is to arrange a partition inside the compartment to achieve sealing, but the sealing effect of the partition assembly is very poor. The other is to set a drawer assembly in the refrigerating and freezing device. The drawer assembly usually includes a sealed barrel and a drawer, and the drawer has a front plate and a drawer body. In order to form a closed storage space inside the drawer, in the prior art, a single strip or ring-shaped seal is usually desig...

AI Technical Summary

Problems solved by technology

However, after the drawer is pushed into the sealed barrel, the pressing force between the two is limited, which is not enough to deform the elastic seal, and the sealing effect is very poor, that is to say, the sealing effect that depends on the external force is very unreliable However, it cannot meet the needs of storage devices that require a higher sealing effect

Moreover, the prior art does not consider the sealing of other positions where there are gaps, resulting in the fact that a real airtight space cannot be formed in the drawer
