Problems solved by technology

If it is necessary to continue vacuum preservation, it is necessary to repeat the vacuuming operation on the vacuum drawer again, resulting in a waste of resources
Therefore, when traditional refrigerators use vacuum drawers for vacuum preservation, the vacuum preservation efficiency is low, which is not conducive to the popularization and application of vacuum preservation technology.

other Embodiment approach

[0061] In other embodiments, the vacuum chamber 36 can also be provided with a position detection device, specifically, a microwave sensor or an infrared sensor can be used to detect whether a packaging bag is inserted into the vacuum chamber 36, and send a signal whether the packaging bag is in place, Controls the vacuuming operation.

[0062] The vacuum assembly 35 communicates with the vacuum cavity 36 . The vacuum assembly 35 is used for vacuuming or depressurizing the vacuum cavity.

[0063] see Figure 4 , the mount 33 is used to carry the vacuum assembly 35 . The vacuum assembly 35 is fixedly installed in the installation groove 221 of the door body 22 through the installation seat 33 . Specifically, in this embodiment, a connecting ear 330 is provided at an edge of the mounting seat 33 , and the mounting seat 33 is connected to the door body 22 through the connecting ear 330 . The connection ear 330 may be in the form of buckles, slots, screw holes and the like.

Abstract

The invention provides a refrigerator. A packaging structure of the refrigerator comprises a refrigerator body and a vacuum packaging structure, wherein a mounting groove is formed in the outer side of the refrigerator body; a sealing plate is arranged at an opening of the mounting groove and is used for sealing the mounting groove; an inserting opening for inserting a packaging bag is formed in the sealing plate; the vacuum packaging structure is mounted in the mounting groove; a first support and a second support of the vacuum packaging structure form a vacuumizing cavity; the packaging bag can enter the vacuumizing cavity from the inserting opening; a vacuumizing assembly comprises a main air path, a vacuumizing air path and a pressure relief air path; the main air path is communicated with the vacuumizing cavity; the vacuumizing air path and the pressure relief air path are communicated with the main air path; the vacuumizing air path is used for vacuumizing the packaging bag in the vacuumizing cavity; the pressure relief air path is used for relieving pressure of the vacuumizing cavity. According to the refrigerator, vacuum packaging is realized through the main air path, the vacuumizing air path and the pressure relief air path, so that the vacuum packaging structure is simple in structure, compact in layout and relatively small in size.

Description

technical field [0001] The invention relates to a household appliance, in particular to a refrigerator. Background technique [0002] A refrigerator is an appliance that maintains low temperatures by keeping food or other items in a constant cold state to avoid spoilage. With the improvement of people's living standards, people's demand for food preservation is also increasing. [0003] To solve the problem of food preservation and storage, vacuum preservation technology has been applied in the field of refrigerators. At present, the refrigerator forms a certain vacuum area by arranging a vacuum drawer in the cabinet, and then the refrigerator performs vacuum preservation for the food materials in the vacuum area. However, for the above-mentioned vacuum preservation method, due to the space limitation of the vacuum drawer, the user usually needs to put all the food materials that need to be vacuum-preserved into the vacuum drawer, and then perform a vacuuming operation, so...
