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 refrigeration and freezing device and a drawer assembly thereof. The drawer assembly comprises a barrel body with the front side opened, a drawer capable of being inserted into the barrel body in a front-and-back push-and-pull manner and an electric control lock mechanism. The electric control lock mechanism is configured to be controllably switched to a locking state so as to lock the drawer to the barrel body or switched to an unlocking state so as to relieve locking on the drawer when the drawer is completely pushed into the barrel body. The electric control lock mechanism is provided with an unlocking button protruding and extending downwards, and the unlocking button is configured to be capable of enabling the electric control lock mechanism to be switched to the unlocking state from the locking state when pressed upwards. According to the refrigeration and freezing device and the drawer assembly thereof, the drawer and the barrel body can achieve automatic locking and unlocking, user operation is facilitated, and the drawer can still be unlocked when the electric control lock mechanism is powered off or breaks down.

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...
