Abstract
A vacuum refreshing device for a refrigerator belongs to the field of vacuum refreshing. The vacuum refreshing device is arranged in a refrigerating box of the refrigerator, and comprises at least one vacuum box, a vacuum generation device for vacuumizing the vacuum box, and a vacuum control device for controlling pumping and preserving of vacuum. Through the arrangement of the vacuum generation device and the vacuum control device in the refrigerator, the degree of vacuum in the vacuum box is controlled well, so that food is isolated from air to be in negative-pressure and hypoxia environment, which prolongs the food refreshing time.
Description
Technical field
The present invention relates to vacuum freshness retaining the field is set, relate in particular to refrigerator and use antistaling vacuum container.
Background technology
Current refrigerator mainly is divided into two kinds with antiseptic preservation technology: (1) deepfreeze is fresh-keeping, and (2) are decomposed airborne pernicious gas etc. with noble metal and reached corrosion-resistanting fresh-keeping effect.More than two kinds of antiseptic preservation technologies commonly used, the anti-corrosive fresh-keeping time is short, can not surpass a week usually, weak effect can not satisfy the demand of meat, preserving fruit and vegetable utilizing, haves much room for improvement.
Summary of the invention
The present invention is directed to the deficiency of prior art, a kind of food air-isolation that lets is provided, be in negative pressure, the low-oxygen environment; Reduce the foodstuff surface oxidation thereby reach, suppress microorganism and generate, effectively reduce oxidation, rotten, mouldy probability; And it is mobile to reduce the foodstuff surface air; Lower water evaporates, make the food anti-corrosive fresh-keeping time longer, the refrigerator of better effects if is used antistaling vacuum container.
The present invention is for solving the problems of the technologies described above; Following technical scheme is provided: a kind of refrigerator is used antistaling vacuum container; It is characterized in that this antistaling vacuum container is arranged in the refrigerator cold-storage casing, the device for vacuum generation that antistaling vacuum container comprises at least one vacuum box body, vacuumize the vacuum box body and the vacuum control unit of control vacuum drawn and maintenance.
As further improvement of the present invention, device for vacuum generation comprises that a vavuum pump and an end are connected with vavuum pump, the vacuum pipe that the other end and vacuum box body are tightly connected.
As further improvement of the present invention, vacuum control unit is the control break-make valve body that is arranged on the vacuum pipe.
As further improvement of the present invention, vacuum pipe is provided with a conducting valve, be provided with in addition on the pipeline of conducting valve rear end one with the bypass duct of atmosphere, bypass duct is provided with a bypass valve.
As of the present invention preferred, described bypass valve is an electromagnet cut off valve.
As of the present invention preferred, conducting valve is electromagnet cut off valve or check valve.
Beneficial effect of the present invention: through device for vacuum generation and vacuum control unit are set in refrigerator, the vacuum in the better controlled vacuum box makes the food air-isolation, is in negative pressure, the low-oxygen environment, thus the fresh keeping time of raising food.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention 1.
Fig. 2 is the structural representation of the embodiment of the invention 2.
The specific embodiment
Below in conjunction with two embodiment, technical scheme of the present invention is further specified, embodiment is not the qualification to concrete structure of the present invention.
Embodiment 1: a kind of refrigerator as shown in Figure 1 is used antistaling vacuum container, and this antistaling vacuum container is arranged in the refrigerator cold-storage casing, the device for vacuum generation that antistaling vacuum container comprises at least one vacuum box body 001, vacuumize vacuum box body 001 and the vacuum control unit of control vacuum drawn and maintenance; Device for vacuum generation comprises that a vavuum pump 002 and an end are connected with vavuum pump 002, and the vacuum pipe 003 that the other end and vacuum box body 001 are tightly connected, vacuum control unit are the control break-make valve body that is arranged on the vacuum pipe 003; Vacuum pipe 003 is provided with a conducting valve 004, and conducting valve 004 is preferably electromagnet cut off valve, be provided with in addition on the conducting valve 004 rear end vacuum pipe 003 one with the bypass duct 005 of atmosphere; Bypass duct 005 is provided with a bypass valve 006, and bypass valve 006 is preferably electromagnet cut off valve, after being placed into the food that needs anti-corrosive fresh-keeping in the vacuum box body 001; Open conducting valve 004, close the bypass valve 006 on the bypass duct 005, let vavuum pump 002 work; Take out the air of vacuum box body 001, after vacuum box body 001 reaches certain vacuum, close conducting valve 004; Make vacuum box body 001 keep vacuum state, stop vavuum pump 002, open the stop valve 006 on the bypass duct 005; Make vavuum pump 002 outlet pressure return to normal atmosphere (An) rapidly, in food is in than the vacuum box body 001 of rough vacuum after because the airborne oxygen content of food contact is very thin; The process of food oxidation is reduced, in addition, the environment of vacuum; A lot of microorganisms can not be bred in a large number; Prevent erosion, cooperate the low temperature of cold compartment of refrigerator, the corrosion-resistanting fresh-keeping effect of food and time are increased greatly food.
Embodiment 2: with reference to embodiment 1, wherein conducting valve 004 is preferably check valve, when vavuum pump 002 work; Being under the positive pressure difference of check valve two ends, one-way valve opens, air flows to vavuum pump 002 through check valve and flows out; When vavuum pump 002 stops, after the electromagnet cut off valve on the bypass duct 005 is opened, because being under the reverse pressure differential of check valve two ends; Closed check valve, thus reach the purpose that keeps vacuum in the vavuum pump 002.
