The body 201 is a square frame structure having a bottom panel 215 and first, second, third and fourth side panels 211, 212, 213 and 214 connected in sequence extending longitudinally upward from the bottom panel 215. When the inner film 221 and the outer film 222 having different elastic deformability are used, the deformed shape of the elastic portion 202, the time for obtaining the deformation of the elastic portion 202, and the like can be adjusted by changing the material of the inner film 221 and the outer film 222.
In some embodiments, the fluid used by the storage device 200 of the refrigerator 100 of the present invention is the liquid 204. The liquid 204 may be a functional liquid with sterilization, radiation protection, cold accumulation or heat release, etc., the functional liquid may sterilize, the radiation affects the respiratory activity of the food 400, the cold accumulation may save energy, and the heat release may prevent frostbite of the food 400. For example, the liquid 204 is a cold storage agent, can inhibit the growth of microorganisms, and has an important effect on the preservation index of frozen foods such as meat, fish and the like in reducing juice loss, volatile basic nitrogen and the like.
In some embodiments, the body portion 201 of the storage device 200 of the refrigerator 100 of the embodiments of the present invention has a pipe inlet; the elastic portion 202 has a liquid inlet. The storage device 200 of the refrigerator 100 according to the embodiment of the present invention further includes: a liquid storage container 205, a liquid delivery pipeline 206 and a pump 207. A liquid storage container 205 is disposed outside the body 201 for storing the liquid 204; one end of the liquid conveying pipeline 206 is connected with the liquid storage container 205, and the other end is connected with the liquid inlet through a pipeline inlet; a pump 207 is provided on the liquid feed line 206 to feed the liquid 204 in both directions. The pump 207 may be provided on one or more sides of the exterior of the body portion 201. The two-way delivery of the liquid 204 includes delivering the liquid 204 from the liquid reservoir 205 to the receiving chamber 220 and delivering the liquid 204 from the receiving chamber 220 to the liquid reservoir 205.
In some embodiments, the pump 207 of the storage device 200 of the refrigerator 100 of the present embodiment is configured to: when the storage space 210 is sealed, the pump 207 is turned on to deliver the liquid 204 from the liquid storage container 205 to the receiving chamber 220, and the pump 207 is turned off after a predetermined time of operation. The storage device 200 of the refrigerator 100 according to the embodiment of the present invention is very simple in that the pump 207 is set to be turned off after the storage space 210 is sealed and then continuously operated for a preset time, and the pump 207 is controlled by time logic.
In some embodiments, the pump 207 of the storage device 200 of the refrigerator 100 of the present embodiment is configured to: when the storage space 210 is sealed, the pump 207 is turned on to deliver the liquid 204 from the liquid storage container 205 to the receiving chamber 220, and the pump 207 is turned off after continuing to operate until the pressure in the storage space 210 reaches a preset pressure. According to the storage device 200 of the refrigerator 100, the pump 207 is arranged to continuously run after the storage space 210 is sealed until the pressure of the storage space 210 reaches the preset pressure, so that accurate control can be realized, and storage and preservation of foods 400 of different types and different volumes are facilitated. Taking meat as an example, when the pressure reaches a certain level, the operation of the pump 207 is stopped, and the pressure state of the storage space 210 is maintained. Because the storage space 210 is smaller, the internal pressure is increased, the respiration of meat is inhibited, and the respiration of meat generates carbon dioxide to further inhibit the respiration of meat, thereby achieving the purpose of fresh-keeping of meat. At the same time, the liquid 204 in the elastic portion 202 also acts on the meat, affecting the respiration intensity of the meat.
In some embodiments, the pump 207 of the storage device 200 of the refrigerator 100 of the present embodiment is further configured to: when the storage space 210 is opened, the pump 207 is turned on to deliver the liquid 204 from the receiving chamber 220 to the liquid storage container 205, and the elastic portion 202 resumes its shape. The storage space 210 of the storage device 200 of the refrigerator 100 according to the embodiment of the present invention should maintain the maximum usage volume as much as possible when not sealed by the cover 203, so as to store more food 400.
In some embodiments, the storage device 200 of the refrigerator 100 according to the embodiment of the present invention further includes a pressure relief device 208 for acting to reduce the pressure in the storage space 210 when the storage space 210 needs to be opened. For example, the pressure relief device 208 is a gas valve. The pressure relief device 208 has a closed state and an open state and is configured such that when in the open state, the storage space 210 is in communication with air outside the storage device 200 via the pressure relief device 208. For example, the pressure release device 208 is a release handle, and when the storage space 210 needs to be opened, the cover 203 can be opened smoothly by pulling the release handle to remove the higher pressure in the storage space 210.
Fig. 4 is a control flow chart of the storage device 200 of the refrigerator 100 of fig. 1. The control method of the storage device 200 of the refrigerator 100 according to the embodiment of the invention comprises the following steps:
