Description

Integral refrigeration compressor compartment freezer with anti-dumping device

technical field

The utility model relates to a refrigerating device, in particular to an integral refrigerating compressor bin freezer with an anti-dumping device which concentrates a refrigerating system in a detachable mechanical room.

Background technique

The compressor, control valve, and condenser in the refrigeration system of the existing vertical freezer or refrigerator are generally all installed at the bottom of the cabinet, and the evaporator and the evaporator fan are mostly installed between the cabinet and the rear side wall of the inner container. In the mezzanine space, once the refrigeration system fails, it needs to be shut down for repair. For commercial refrigerators used for displaying goods, such as cola or other beverage cabinets, downtime repairs will affect sales.

In the 02227530 utility model patent, a compressor compartment of a refrigerator and a freezer is proposed. It includes bottom plate, left and right side walls, front and rear walls, and refrigeration elements fixed on the bottom plate in the compressor compartment. The left and right side walls are respectively provided with guide rails extending along the width direction of the left and right side walls, and the bottom plate is movably erected on the guide rails. And it can slide along the length direction of the guide rail so that the refrigeration element enters and exits the compressor compartment along with the bottom plate from the front wall or the rear wall. This patent only provides that the refrigerating elements in the compressor chamber can be pushed or pulled out along the guide rails, thereby facilitating installation and maintenance, and reducing installation and maintenance costs.

Usually, for the convenience of moving the refrigerator, four front and rear rollers 35 are arranged at the bottom of the refrigerator as shown in Figure 1. For tall refrigerators, the rollers at the bottom of the front and rear are easy to cause front and rear toppling, especially for the whole refrigeration system centralized For a freezer or refrigerator in a compressor compartment, when the compressor compartment is removed, because the refrigeration system is quite heavy, once the center of gravity moves out of the previous set of roller shafts during the removal process, the refrigerator will tilt forward.
