The vacuum degree adjustable and visualized system further comprises a display and operation device, specifically comprising a display panel 600 or a mobile terminal.

The display and operation device is used for displaying the dynamic vacuum pressure value and setting a preset vacuum pressure value A, and the range of the preset vacuum pressure value A is as follows: a is more than or equal to 20KPA and less than or equal to OKPA, and a preset vacuum pressure value A can be set through a display and operation device; the dynamic vacuum pressure value is a variable vacuum pressure value in the sealed cavity obtained by the vacuum pressure sensor 400 in real time, is transmitted to the controller, and is displayed on the display and operation device;

when the display and operation device is the display panel 600, the display panel 600 is installed outside the refrigerator body 100, referring to fig. 16 (the door 110 does not show the outer shell of the door 110 in the figure), which is convenient for a user to monitor the operation condition of the vacuum storage area 200 in the refrigerator in real time, and further realizes the management and control and adjustment of the vacuum degree in the vacuum storage; when the display and operation device is a mobile terminal, the user can be connected to the controller of the vacuum degree adjustable and visual system through wireless communication, so that the operation condition of the vacuum storage area 200 in the refrigerator can be monitored in real time, and the control and the adjustment of the vacuum degree in the vacuum storage are further realized.

In addition, the vacuum pressure value suitable for the daily storage articles of the user is-20 KPA to OKPA, and-10 KPA is suitable for the storage of fruits and vegetables, and-20 KPA is suitable for the storage of meat and dry goods, so the range of the preset vacuum pressure value A is set as follows: -20KPA ≤ A ≤ OKPA.

The vacuum degree adjustable and visual system also comprises a controller, and the controller is a programmable logic controller.

The controller is used for controlling the work of each component in the vacuum degree adjustable and visual system.

The controller is disposed on the refrigerator body, and the contact switch 300, the vacuum pressure sensor 400, the vacuum pump 500 and the display panel 600 are electrically connected to the controller through a plurality of wires, and meanwhile, the plurality of wires are disposed inside the refrigerator, thereby preventing the user from using the refrigerator or causing danger due to the fact that the wires are exposed on the surface of the refrigerator body 100 or in the storage space in the storage chamber.

In the working process of the vacuum pump 500, when the contact switch 300 is closed and the dynamic vacuum pressure value is smaller than the preset vacuum pressure value a, the vacuum pump 500 performs air extraction on the sealed cavity; when the dynamic vacuum pressure value is greater than or equal to the preset vacuum pressure value a or the contact switch 300 is turned off, the vacuum pump 500 stops pumping the sealed cavity.

When the refrigerator with the vacuum degree adjustable and visual system is used, firstly, articles to be stored are placed in the vacuum storage area 200, the storage area is locked, the contact switch 300 is closed, then, according to the attributes of the articles, a vacuum pressure value suitable for article storage is input on the display and operation device, a preset vacuum pressure value A is set, at the moment, the dynamic vacuum pressure value in the vacuum storage area 200 is smaller than the preset vacuum pressure value A, and the vacuum pump 500 is started and pumps air to the sealed cavity; when the dynamic vacuum pressure value in the sealed cavity is greater than or equal to the preset vacuum pressure value a after the vacuum pump 500 works for a period of time, the vacuum pump 500 stops working and stops pumping air to the sealed cavity.

In addition, when the vacuum pump 500 is in operation, the vacuum storage area 200 needs to be opened to take out the article, the contact switch 300 is firstly disconnected, the locking end of the locking mechanism 800 is separated from the locking area of the vacuum storage area 200, the vacuum pump 500 stops operating, the sealed cavity is stopped being pumped, and the article can be taken out from the vacuum storage area 200.

It should be noted that, by using the adjustable and visualized vacuum degree system in the present application, the operation condition of the vacuum storage area 200 in the refrigerator body 100 can be monitored in real time, and the vacuum pressure value in the vacuum storage area 200 can be controlled and adjusted.

In addition, the adjustable vacuum degree and visualization system can also be used for detecting whether the refrigerator to be delivered from a factory is qualified.

According to the refrigerator detection method in the embodiment of the present application, referring to fig. 2 and 11, the refrigerator detection method includes step S1, locking the vacuum storage area 200, closing the contact switch 300, setting the preset vacuum pressure value a to-20 KPA, and comparing the dynamic vacuum pressure value with the preset vacuum pressure value a to determine the airtightness of the vacuum tube 510 and the vacuum storage area 200.

In other words, the vacuum storage area 200 is locked by the locking mechanism 800, and the contact switch 300 is automatically closed or operatively closed by pressing the contact switch 300 to secure airtightness between the cover plate 210 and the storage area body 220. And setting the preset vacuum pressure value to-20 KPA, starting the vacuum pump 500 and exhausting the vacuum storage area 200, displaying the dynamic vacuum pressure value in the sealed cavity through the display and operation device, comparing the dynamic vacuum pressure value with the preset vacuum pressure value A after the preset time, and judging whether the air tightness of the vacuum tube 510 and the vacuum storage area 200 is good or not according to the comparison result.

When the dynamic vacuum pressure value is less than-20 KPA, the vacuum tube 510 and the vacuum storage area 200 have air tightness faults, and the refrigerator is unqualified; when the dynamic vacuum pressure value can reach-20 KPA, or the pressure value is smaller, it indicates that the airtightness of the vacuum tube 510 and the vacuum storage area 200 of the refrigerator is good, and the process proceeds to step S2.

Specifically, if the dynamic vacuum pressure value is less than-20 KPA, it indicates that the vacuum pressure values in the vacuum tube 510 and the vacuum storage area 200 are less than the preset vacuum pressure value a, and there must be damaged portions in the vacuum tube 510 and the vacuum storage area 200, that is, an air-tight fault occurs in the vacuum tube 510 and a sealed cavity in the vacuum storage area 200; the dynamic vacuum pressure value can reach-20 KPA, or the pressure value is smaller, which indicates that the vacuum pump 500 can completely pump away the gas in the vacuum tube 510 and the vacuum storage area 200, and the vacuum pressure value in the vacuum tube 510 and the vacuum storage area 200 cannot reach the preset vacuum pressure value a because there is no damage at any position in the vacuum tube 510 and the vacuum storage area 200, that is, the air tightness of the sealed cavity in the vacuum tube 510 and the vacuum storage area 200 is good.

In addition, in step S1, the problem of the leak tightness of the vacuum tube 510 and the vacuum storage area 200 due to the damage of a portion of the vacuum tube 510 and the vacuum storage area 200 is eliminated, and the leak tightness of the vacuum tube 510 and the vacuum storage area 200 is not damaged in the process of step S2.

In some embodiments of the present application, step S2, the cover 210 is opened, the contact switch 300 is closed, the preset vacuum pressure value a is set to any value within the range of the preset vacuum pressure value a, and the dynamic vacuum pressure value is compared with the preset vacuum pressure value a to determine whether the vacuum tube 510 is unblocked.

In other words, when the cover 210 is opened, the contact switch 300 needs to be manually pressed to be closed, the vacuum tube 510 and the sealed cavity in the vacuum storage area 200 are in an open state, a preset vacuum pressure value a is set to any value within a preset vacuum pressure value a range, after a preset time, a dynamic vacuum pressure value is finally displayed through the display and operation device, the dynamic vacuum pressure value is compared with the preset vacuum pressure value a, and whether the vacuum tube 510 is unblocked is judged according to a comparison result.

When the dynamic vacuum pressure value does not reach the preset vacuum pressure value A, the vacuum tube 510 is unblocked, and the refrigerator to be delivered from the factory is qualified; when the dynamic vacuum pressure value reaches the preset vacuum pressure value A or is smaller than the preset vacuum pressure value A, the vacuum tube 510 is blocked, and the refrigerator to be delivered is unqualified.

Specifically, if the dynamic vacuum pressure value does not reach the preset vacuum pressure value a, it indicates that the vacuum storage area 200 is not sealed, that is, one end of the vacuum tube 510 is in an open state, and if the vacuum pump 500 pumps away the gas in the vacuum tube 510 and the vacuum storage area 200, the gas will immediately enter the sealed cavity and the vacuum tube 510 in the vacuum storage area 200, so that the vacuum pressure values in the vacuum tube 510 and the vacuum storage area 200 are lower, and if the dynamic vacuum pressure value does not reach the preset vacuum pressure value a, the pipeline in the vacuum tube 510 is inevitably unblocked; when the dynamic vacuum pressure value reaches the preset vacuum pressure value a or is smaller, it indicates that the vacuum pump 500 can pump the gas in the vacuum tube 510 away when one end of the vacuum tube 510 is in an open state, that is, when the vacuum pump 500 pumps the gas in the vacuum tube 510 and the vacuum storage area 200 away, the gas cannot enter because the vacuum tube 510 is blocked, so that the vacuum pressure value in the vacuum tube 510 reaches the preset vacuum pressure value a or is smaller, that is, the pipeline of the vacuum tube 510 is blocked.
