Abstract
The utility model discloses a vacuum freshness-keeping device for refrigerators, which belongs to the field of vacuum freshness-keeping. The vacuum freshness-keeping device is arranged in a refrigerated container body of a refrigerator, and comprises at least a vacuum box body, a vacuum generating device and a vacuum control device, wherein the vacuum generating device is used for carrying out vacuumizing on the vacuum box body, the vacuum control device is used for controlling vacuum extraction and maintaining. Through setting the vacuum generating device and the vacuum control device in a refrigerator, the vacuum degree of the inside of a vacuum box is controlled well, so that the food is isolated from air and in a negative-pressure and low-oxygen environment, thereby improving the freshness-keeping time of the food.
Description
Technical field
The utility model relates to vacuum freshness retaining the field is set, and relates in particular to refrigerator and uses 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 utility model provides a kind of food air-isolation that lets to the deficiency of prior art, is 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 utility model 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 the further improvement of the utility model, 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 the further improvement of the utility model, vacuum control unit is the control break-make valve body that is arranged on the vacuum pipe.
As the further improvement of the utility model, 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.
Preferred as the utility model, described bypass valve is an electromagnet cut off valve.
Preferred as the utility model, conducting valve is electromagnet cut off valve or check valve.
The beneficial effect of the utility model: 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.

Fig. 1 is the structural representation of the utility model embodiment 1.
Fig. 2 is the structural representation of the utility model embodiment 2.
The specific embodiment
Below in conjunction with two embodiment, the utility model technical scheme is further specified, embodiment is not the qualification to the utility model concrete structure.
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.
