Embodiment 1

[0042] 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.

[0043] The storage room 100 has an open box, and the storage room 100 is vertically divided into a lower freezing room 100A and an upper cooling room 10...

other Embodiment approach

[0046] In other embodiments, the above-mentioned vacuum packaging device 300 can also use the upper support 320 to be fixedly connected to the door body 200 , and the driving device 340 drives the lower support 310 to move up and down so as to approach the upper support 320 to realize the docking and sealing of the two.

[0047] Specifically, in order to improve the sealing performance of the sealed chamber 301, as Figure 7 As shown, a sealing portion for sealing the sealed chamber 301 is provided on the opposite surface of the lower support 310 and the upper support 320 . Specifically, the lower support 310 is provided with a first sealing groove 313 on the outer periphery of the first opening 311 , and the upper support 320 is provided with a second sealing groove 323 on the outer periphery of the second opening 321 , the first sealing groove 313 is opposite to the second sealing groove 323 and has a sealing ring 350 inside. The two sealing rings 350 arranged in the first ...

Embodiment 2

[0084] This embodiment 2 is another embodiment of the refrigerator provided by the present invention, which is basically the same as the embodiment 1, the difference is that in this embodiment, in order to further improve the operation safety, the The vacuum packaging operation leads to the problem that the storage bag is vacuumed slowly or cannot be vacuumed. The vacuum packaging device is provided with an in-position detection device and an indicating device for displaying the operating status of the vacuum packaging device; wherein the in-position detection device is used to detect Whether there is a storage bag inserted into the sealed chamber 301, and then send a signal to the controller whether the storage bag is in place, at least two in-position detection devices are provided, and when the sealed chamber is received by the control device When there are detection signals fed back by two or more in-position detection devices 380, it means that the storage bag is inserted ...

Abstract

The invention discloses a refrigerator. The outer side of a door body of the refrigerator is provided with a vacuum packaging device, the vacuum packaging device comprises an upper support and a lowersupport which are oppositely arranged up and down, the upper support is driven by a driving device to move up and down so as to be close to or far away from the lower support, the opposite surfaces of the upper support and the lower support are in butt joint to form a sealed cavity from inside to outside, and the vacuum packaging device further comprises at least two in-place detection devices and an indication device. When detection signals fed back by the two or more in-place detection devices are received, a control device controls the indication device to send out in-place indication signals, and when only the detection signal fed back by one in-place detection device is received, the indication device is controlled not to send out the in-place indication signal. According to the refrigerator, a storage bag containing food materials can be subjected to vacuum packaging treatment, and the fresh-keeping range is enlarged; and whether the storage bag is inserted in place or not is detected through the in-place detection devices, so that a user knows that the storage bag is inserted in place and then carries out operation, and safety is improved.

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...
