Refrigeration appliances

Abstract

The invention relates to a refrigeration device. The device comprises: a body (2) that defines a storage compartment (4), said compartment (4) having a rear wall (4a) and a lateral wall (4c) that extends vertically; a first connecting piece (72) that lies exposed in the storage compartment (4) and is in fluidic connection with an air evacuation device (70); and a low-pressure storage unit (7) having a storage chamber (32) from which air can be evacuated, which is constructed independently of the body (2) and is accommodated in the storage compartment (4). The low-pressure storage unit (7) has an evacuation channel and the evacuation channel has a second connecting piece (39) for a fluidic connection to the first connecting piece (72). According to one embodiment of the invention, the first connecting piece (72) extends from the lateral compartment wall (4c) into the storage compartment (4).

Description

[technical field] [0001] The present invention relates to a refrigerating appliance, in particular to a refrigerating appliance capable of storing articles in a low-pressure environment. [Background technique] [0002] Refrigeration appliances that can store items in a low pressure environment are known in the prior art. Such refrigerating appliances usually have an evacuable storage chamber. By evacuating the gas in the storage chamber, the air content in the storage chamber is reduced to weaken the oxidation process of the food, thereby prolonging the preservation time and quality of the food. [0003] In the refrigerator disclosed in Chinese patent application CN101342970A with an evacuatable storage room (also known as "low-pressure room"), the evacuable storage room is composed of low-pressure storage chambers that are independent of the cabinet structure and are movably accommodated in the refrigerator. Box limited. The box body is provided with a vacuum pump used to...

AI Technical Summary

Problems solved by technology

[0004] People cannot observe whether the connection between the connection nozzle at the back of the low-pressure storage box and the connection head at the end of the fluid pipeline is in place, and a slight misalignment between the two may cause the airtight connection between the connection nozzle and the fluid pipeline reduced, so the reliability and airtightness of the connection between the low-pressure storage box and the vacuum pump cannot be guaranteed

In addition, when foreign matter exists, it will also affect the airtightness of the connection between the two

Further, since the connection cannot be realized under the condition of people's vision, the connection between the connection nozzle on the back of the low-pressure storage box and the end of the fluid pipeline can only be limited to a flexible connection

[0005] In addition, there is usually an evaporator near the rear wall of the refrigerating room. This solution of passing the fluid pipeline through the back wall of the refrigerating room into the refrigerating room has disadvantages: on the one hand, the fluid close to the evaporator or even in direct contact with the evaporator The inside of the pipeline may freeze, and in the long run, it may block the fluid pipeline and reduce the reliability of the low-pressure storage box; on the other hand, the structure of the evaporator (especially the plate evaporator) needs to be redesigned to be reasonable. Arrangement of fluid lines and correspondingly complex installation of evaporators and fluid lines
