Problems solved by technology

[0003] For this reason, the existing refrigerating and freezing devices are equipped with complex mechanical or electromagnetic locking mechanisms to lock the drawer and the cylinder body, but the existing locking mechanisms have complex structures and are difficult to manufacture, or the operation is cumbersome and difficult to control, or the cost is relatively high
In addition, some locking mechanisms based on electromagnetic or electric principles cannot open the drawer normally when the power is off, which brings a lot of inconvenience to users.

Abstract

The invention relates to a refrigerating and freezing device and a drawer assembly thereof. The drawer assembly comprises a tank with the front side open, a drawer capable of being inserted into the tank in a front-back push-pull mode, an electronic control lock mechanism arranged on the rear side of the outer portion of the tank and an unlocking lead, wherein the electronic control lock mechanism can be controlled to be switched to a locking state so as to lock the drawer to the tank wen the drawer is pushed into the tank completely or switched to an unlocking state so as to unlock the drawer; the unlocking lead extends from the front end of the tank to the electronic control lock mechanism along the outer surface of the tank; the electronic control lock mechanism can be switched from the locking state to the unlocking state when the unlocking lead is pulled. According to the refrigerating and freezing device and the drawer assembly thereof, the drawer and the tank can be locked and unlocked automatically, a user can operate the drawer assembly conveniently, and the drawer can still be unlocked in case of outages or failures of the electronic control lock mechanism.

Description

technical field [0001] The invention relates to a refrigerating device, in particular to a refrigerating and freezing device and a drawer assembly thereof. Background technique [0002] The drawer of the refrigerating and freezing device is generally arranged in a cylindrical body in a push-and-pull manner. With the improvement of food preservation requirements, it is necessary to form a good seal between the front panel of the drawer and the opening of the cylinder after the drawer is fully pushed into the cylinder, that is, it is necessary to make the front panel close to the opening of the cylinder. [0003] For this reason, the existing refrigerating and freezing devices are equipped with complex mechanical or electromagnetic locking mechanisms to lock the drawer and the cylinder body, but the existing locking mechanisms are complex in structure and difficult to manufacture, cumbersome in operation and difficult to control, or high in cost . In addition, some locking m...
