Description

Refrigerator with a refrigerator body Technical Field The utility model relates to the technical field of refrigeration equipment, in particular to a refrigerator. Background The refrigerator is internally provided with a drawer frame body, a drawer cavity with a front side opening is formed in the drawer frame body, a vacuum drawer can be placed in the drawer cavity through the front side opening of the drawer cavity, the drawer cavity is further sealed, a sealed space is formed in the drawer cavity, vacuum pumping is carried out through a vacuum pump, and a certain vacuum environment is further kept in the vacuum drawer, so that the food fresh-keeping effect is improved. The refrigerator is also provided with a pressure detecting device for detecting the pressure in the drawer cavity. The existing refrigerator has the defects that the cost is high, and due to the fact that the humidity in the vacuum drawer is high, particularly when fruits and vegetables are stored, condensation is easily generated due to the fact that the vacuum drawer is airtight, the application reliability of the electronic pressure switch on the vacuum drawer is reduced, and the service life of the electronic pressure switch is shortened. The existing pressure detection device adopts an installation mode of being directly installed on a drawer frame body, and a drawer cavity directly acts on an internal deformation part of the pressure detection device. The drawer frame body and the pressure detection device can be detected and tested after being installed, and the production efficiency of the refrigerator is reduced. The above information disclosed in this background section is only for enhancement of understanding of the background section of the application and therefore it may not form the prior art that is already known to those of ordinary skill in the art. Disclosure of Invention Aiming at the problems pointed out in the background technology, the utility model provides a refrigerator, which improves the pressure detection reliability of a vacuum drawer and improves the production efficiency. In order to achieve the aim of the utility model, the utility model is realized by adopting the following technical scheme: In some embodiments of the present application, a refrigerator is provided, a refrigeration compartment is formed in a refrigerator liner, a drawer frame is disposed in the refrigeration compartment, a drawer cavity with an open front side is formed in the drawer frame, a first interface is disposed on a wall of the drawer frame, a vacuum drawer is disposed in the drawer cavity, a pressure detection device is detachably disposed on the wall of the drawer frame, the pressure detection device is connected with the first interface through a first pipeline, the pressure detection device is configured to detect pressure in the drawer cavity, the pressure detection device feeds back a signal when detecting that the pressure in the drawer cavity is 0.7-0.92atm, and the pressure detection device is a diaphragm mechanical pressure switch. The technical scheme has the following advantages or beneficial effects: The wall of the drawer frame body is provided with a first interface, and the pressure detection device is connected with the first interface through a first pipeline, so that the gas pressure in the drawer cavity is transmitted to the pressure detection device through the first pipeline. The pressure detecting device is mounted to the drawer frame as a separate electrical device. During production of the refrigerator, the pressure detection device can be tested firstly, then the reliable pressure detection device is connected with the first interface on the drawer frame body through the first pipeline, and the pressure detection device is not required to be mounted on the drawer frame body and then tested as in the background art, so that the production efficiency of the refrigerator is improved. The pressure detecting means feeds back a signal when detecting that the pressure in the drawer chamber is 0.7-0.92 atm. For example, the pressure detecting device feeds back a signal when detecting that the pressure in the drawer cavity is 0.7-0.8atm, and the pressure value is suitable for storing low-humidity food materials, because the pressure value can cause serious water loss of food for part of the food materials, such as spinach, lettuce and other leaf vegetables. For another example, the pressure detecting means feeds back a signal when detecting that the pressure in the drawer cavity is 0.8-0.92atm, and the pressure value is suitable for most food storage. Through the range setting of the pressure values, the pressure detection device can detect more reliably and accurately in the application scene of the vacuum drawer. The pressure detection device adopts the diaphragm mechanical pressure switch, so that the influence of humidity in the vacuum drawer on the pressure detection device is avoided, and the pressure dete
