Problems solved by technology

[0004] However, after the low-pressure chamber is evacuated or the low-pressure storage unit is used for a long time, the low-pressure chamber door and / or handle may be deformed to a certain extent, so that the distance between the door body and the inner side of the handle changes, which causes the pressure relief valve A decrease in airtightness during closing, which in turn affects the airtightness of the low-pressure storage unit

Embodiment Construction

[0033] Please refer to figure 1 , the refrigeration appliance 1 includes a heat-insulated box body 2, and the box body 2 includes an outer shell 2a, an inner tank 2b, and a thermal insulation layer (not shown) between them. The box body 2 defines a plurality of insulated storage compartments 3, 4, 5 for storing food and other items. In this embodiment, these storage compartments are the refrigerated compartment 3 at the top, the freezer compartment 5 at the bottom, and the fresh-keeping compartment 4 located between the former two with a temperature slightly higher than zero degrees Celsius. The storage compartments 3, 4, 5 can be closed by respective appliance doors (not shown).

[0034] It should be understood that the present invention should not be limited to the specific distribution form of the storage compartments of the refrigerating appliance, and the present invention can also be applied to other forms of refrigerating appliances, such as refrigerators and storage c...

Abstract

A low-pressure storage unit (7), comprising: a storage chamber (15) capable of maintaining a low-pressure state; a first portion (26) having a through hole (19) for communicating the storage chamber (15) with an external fluid; and a second portion (32) provided with a closure member (25) for selectively opening or closing the through hole (19), characterized in that, the closure member (25) is adjustably connected to the second portion (32) at a position relative to the second portion (32).

Description

[technical field] [0001] The present invention relates to a low-pressure storage unit and a refrigerating appliance with the low-pressure storage unit, in particular to a low-pressure storage unit with a closure for closing a fluid passage and a household or commercial refrigerating appliance with the storage unit. [Background technique] [0002] Chinese patent application CN 101358795 A discloses a refrigeration appliance with a low-pressure storage unit (also called a "vacuum storage unit"). The low-pressure storage unit includes a main body defining a storage room with a food access opening and a door for opening and closing the access opening. A sealing element around the access opening is provided between the door and the main body to make the low-pressure storage unit form a vacuum seal, so that when the storage room is closed, the gas in the storage room can be sucked away by a suction device such as a vacuum pump to make the storage room Keep the low pressure state,...
