Abstract
The invention discloses a vacuum chamber control method for a refrigerator, and relates to the technical field of refrigerators. The invention comprises a vacuum chamber, a vacuum pump, a pressure sensor, a temperature and humidity sensor and a pressure release valve; the pressure sensor and the temperature and humidity sensor are placed in the vacuum chamber, the pressure release valve is installed on the side wall of the vacuum chamber, and the vacuum pump is connected with the vacuum chamber through a pipeline and a one-way valve. According to the invention, the humidity in the vacuum chamber is judged through the temperature and humidity sensor, the pressure in the vacuum chamber is judged through the pressure sensor, and the pressure relief or the injection of fresh air is carried out on the vacuum chamber through the pressure relief valve. When the humidity reaches a preset value, closing the pressure release valve, and vacuumizing the vacuum chamber; when the pressure reaches a preset value, the vacuumizing is stopped, the replacement of fresh air in the vacuum chamber is further realized, and after a certain time, the vacuum chamber is vacuumized again, so that the problem that food in the vacuum chamber is rotten can be effectively solved.
Description
Technical Field
The invention belongs to the technical field of refrigerators, and particularly relates to a vacuum chamber control method for a refrigerator.
Background
As is well known, the vacuum packaging of food can effectively solve the problems of food oxidation, taint of odor, mildew and the like, and the food can be stored for a longer time, for example, the vacuum packaging is adopted. However, unlike so-called vacuum packaging, the vacuum compartment in the refrigerator compartment is only evacuated to a certain extent to remove oxygen and reduce pressure, and thus cannot achieve a true vacuum state, and the food therein cannot be preserved for a long time. If only simply bleed air and decompress in the refrigerator vacuum room, can lead to melon and fruit vegetables to carry out the anaerobic respiration, and inside humidity can be bigger and bigger, causes the rotten of food.

The invention aims to provide a vacuum chamber control method for a refrigerator, which is characterized in that the humidity in a vacuum chamber is judged through a temperature and humidity sensor, the pressure in the vacuum chamber is judged through a pressure sensor, and the vacuum chamber is decompressed or injected with fresh air through a decompression valve. When the humidity reaches a preset value, closing the pressure release valve, and vacuumizing the vacuum chamber; when the pressure reaches a preset value, the vacuumizing is stopped, the replacement of fresh air in the vacuum chamber is further realized, and after a certain time, the vacuum chamber is vacuumized again, so that the problem that food in the vacuum chamber is rotten can be effectively solved.
In order to solve the technical problems, the invention is realized by the following technical scheme:
the invention relates to a vacuum chamber control method for a refrigerator, which comprises a vacuum chamber, a vacuum pump, a pressure sensor, a temperature and humidity sensor and a pressure release valve, wherein the vacuum chamber is provided with a vacuum chamber; the pressure sensor and the temperature and humidity sensor are arranged in the vacuum chamber, the pressure release valve is arranged on the side wall of the vacuum chamber, and the vacuum pump is connected with the vacuum chamber through a pipeline and a one-way valve;
the method comprises the following steps:
presetting time T1 and T2, a preset humidity value T1 and a preset pressure value T2;
step two, judging that the working time T is less than or equal to T1, if not, executing step three, if so, judging whether the numerical value of the temperature and humidity sensor reaches a preset humidity value T1, if so, closing the pressure release valve, and executing step five; if not, executing the fourth step;
step three, the refrigerator gives an alarm to remind, and meanwhile, the vacuum chamber stops working;
step four, continuously opening the pressure release valve, and executing step two;
step five, judging that the working time T is less than or equal to T2, if not, executing step three, if so, judging whether the numerical value of the pressure sensor reaches a preset pressure value T2, if so, stopping vacuumizing by the vacuum pump, and if not, executing step six;
and step six, continuously vacuumizing by using a vacuum pump, and executing step five to circulate.
And further, in the fifth step, the vacuum pump performs vacuum pumping through a one-way valve.
Furthermore, the cycle time in the fifth step and the sixth step is T hours, T1 is less than or equal to T, and T2 is less than or equal to T.
The invention has the following beneficial effects:
according to the invention, the humidity in the vacuum chamber is judged through the temperature and humidity sensor, the pressure in the vacuum chamber is judged through the pressure sensor, and the pressure relief or the injection of fresh air is carried out on the vacuum chamber through the pressure relief valve. When the humidity reaches a preset value, closing the pressure release valve, and vacuumizing the vacuum chamber; when the pressure reaches a preset value, the vacuumizing is stopped, the replacement of fresh air in the vacuum chamber is further realized, and after a certain time, the vacuum chamber is vacuumized again, so that the problem that food in the vacuum chamber is rotten can be effectively solved.
Of course, it is not necessary for any product in which the invention is practiced to achieve all of the above-described advantages at the same time.
