Embodiment 1

[0045] figure 1 It is a perspective view of a specific embodiment of the refrigerator of the present invention; refer to figure 1 , the refrigerator 1 of the present embodiment has an approximately rectangular parallelepiped shape. The appearance of the refrigerator 1 is defined by a storage room 100 defining a storage space and a plurality of doors 200 provided in the storage room 100, wherein, referring to figure 2 The door body 200 includes a door body casing 210 located outside the storage room 100, a door inner container 220 located inside the storage room 100, an upper end cover 230, a lower end cover 240, and a door body outer casing 210, a door inner container 220, The heat insulating layer between the upper end cover 230 and the lower end cover 240; usually, the heat insulating layer is filled with foam material.

[0046] The storage room 100 has an open box, and the storage room 100 is vertically divided into a lower freezing room A and an upper cooling room 100B....

Embodiment 2

[0081] The structure of the second embodiment is basically the same as that of the first embodiment, the difference lies in the connection method between the lower support 310 and the small heat preservation door 250 . Specifically, in this embodiment, refer to Figure 24A , Figure 24B As shown, the lower support 310 is detachably connected to the small heat preservation door 250 . Such as Figure 25 The thermal insulation door 250 shown is formed by a first shell 251 and a second shell 252 with an open cavity structure and an insulating member arranged between the first shell 251 and the second shell 252 . Wherein, the first housing 251 is snap-connected with the second housing 252, the first housing 251 is provided with an extension arm 2511 in a direction away from the second housing 252, and the lower support 310 is detachably connected. on the extension arm 2511 .

[0082] Specifically, the end of the extension arm 2511 is formed with a first limiting portion extendi...

Embodiment 3

[0088] The structure of this embodiment 2 is basically the same as that of the embodiment 1, the difference lies in the connection method between the lower support 310 and the small heat preservation door 250 and the door body 200 .

[0089] Such as Figure 26A-Figure 26C As shown, the lower support 310 and the small heat preservation door 250 are set independently of each other, and the lower side of the installation hole 201 is provided with a limiting part that limits the position of the lower support 310. The lower support 310 One end abuts against the limiting portion, and the other end abuts against the small heat preservation door 250 . The thermal insulation door 250 can be installed on the door body 200 by using the locking device 400 in the first or second embodiment.

Abstract

The invention discloses a refrigerator. The refrigerator comprises a storage chamber and a door body for opening or closing the storage chamber, wherein the door body comprises a door body shell, a door body inner container, an upper end cover and a lower end cover, wherein a mounting cavity is formed in the door body shell, a vacuumizing assembly is arranged in the mounting cavity, and the vacuumizing assembly comprises a vacuum pump; the door body is provided with a bar counter door at the opening part of the mounting cavity, and the lower end of the bar counter door is hinged with the doorbody; the bar counter door comprises a bar counter door inner plate and a bar counter door outer plate; the bar counter door inner plate and / or the bar counter door outer plate are / is provided with anair exhaust pipe connector; the air exhaust pipe connector is communicated with the vacuum pump through an air exhaust pipe; and a cavity used for containing the air exhaust pipe is formed between the bar counter door inner plate and the bar counter door outer plate. The refrigerator disclosed by the invention can be used for carrying out vacuum packaging treatment on a sealed tank filled with the food materials; and food materials stored in various chambers of the refrigerator can be subjected to vacuumizing fresh-keeping treatment, so that the fresh-keeping range is enlarged.

Description

technical field [0001] The present invention relates to the field of home appliances, and in particular to a refrigerator. Background technique [0002] In recent years, people's health awareness has gradually increased, and the demand for food preservation has also increased. Refrigerators are the most commonly used household appliances for food storage, and food preservation and storage has become an urgent technical demand in the refrigerator field. [0003] At present, various manufacturers have introduced different fresh-keeping technologies for the preservation and storage of food materials. For example, vacuum preservation technology, under the vacuum state, the conditions for food deterioration have changed. First of all, in a vacuum environment, microorganisms and various promoting enzymes are difficult to survive, and it takes a long time to meet the requirements of microbial growth; secondly, in a vacuum state, the oxygen in the container is greatly reduced, vari...
