The refrigerator 10 is provided with a ventilation device 340 disposed in the sealing barrel 310 and configured to communicate the inner space of the sealing barrel 310 with the first storage space when opened, so as to exchange gas between the inner space of the sealing barrel 310 and the first storage space.

The refrigerator 10 of the present embodiment is preferably refrigerated by an air cooling method, and the internal humidity of the first storage space is lowered when the first storage space is refrigerated. Therefore, the ventilation device 340 can open the sealed tub 310 when the humidity of the air in the sealed tub 310 is higher than the humidity of the air in the first storage space, thereby reducing the humidity of the air in the sealed tub 310.

In this embodiment, the humidity inside the case 12 and the inside of the first door 200 may be detected by a humidity detection device. The first humidity detection device 331 is disposed in the first storage space and is configured to detect the humidity of the air in the first storage space. The second humidity detecting device 332 is disposed inside the sealed tub 310 and is used for detecting the humidity of the air inside the sealed tub 310. The ventilation device 340 is also configured to be turned on when the humidity of the air inside the sealed tub 310 is greater than the humidity of the air inside the first storage space. Thereby when sealed drawer 300 humidity is great, reduce sealed drawer 300's humidity through taking a breath with first storing space, prolong the shelf life of eating the material, improve fresh-keeping effect.

To further satisfy the requirement of the sealed drawer 300 for storing tea leaves or other dry goods, the refrigerator 10 of the present embodiment may further be provided with an air extractor 350. The air-extracting device 350 is disposed inside the sealed tub 310 and configured to be turned on after the humidity of the air inside the sealed tub 310 is less than the humidity of the air inside the first storage space, so as to perform a vacuum-pumping operation on the sealed tub 310.

The refrigerator of the present embodiment also optimizes the configuration of the sealing tub 310 in order to increase the usable volume of the sealing tub 310. An accommodating cavity is formed in one side, close to the first storage space, of the sealed barrel body 310, and the accommodating cavity and the region where the pull box 320 is located are separated by a partition wall; the air-extracting device 350 and the air-exchanging device 340 are respectively arranged in the accommodating cavities. The rear wall of the receiving chamber is purposely hidden in fig. 5 in order to show the internal configuration of the receiving chamber. The receiving cavity may be a bar shape and is disposed at the top or bottom of the sealing barrel 310, and the interior thereof provides a space for installing the air-extracting device 350 and the air-exchanging device 340. The partition wall 312 may be opened with a through hole for connecting the air-extracting device 350 and the air-exchanging device 340 to the inside of the sealing barrel 310.

The suction device 350 may include: check valve 351 and vacuum pump 352. The check valve 351 is disposed on the partition wall 312 and configured to allow air of the area where the drawer box 320 is located to flow toward only one side of the receiving chamber, thereby preventing external air from entering the sealing tub 310 through the partition wall 312. The vacuum pump 352 is transversely disposed in the accommodating chamber and is connected to one side of the one-way valve 351 through an air suction pipe (not shown).

The ventilation device 340 may include a ventilation valve 341 disposed on a wall of the accommodating cavity facing the first storage space; a ventilation tube (not shown) extends from the ventilation valve 341 to the partition wall 312, communicating with the area where the drawer box 320 is located.

The ventilating device 340 and the air exhausting device 350 are configured to be allowed to be activated only when both the first door 200 and the second door 110 are in the closed state, so as to prevent the outside air from affecting the humidity detection results of the first humidity detecting device 331 and the second humidity detecting device 332 after the doors are opened. The refrigerator of the present embodiment may be further provided with an open/close door detector 333. An open/close door detector 333 configured to sense an open/close state of the first door 200 and the second door 110, thereby providing the air exchange device 340 and the air exhaust device 350 with the open/close state of the first door 200 and the second door 110. The open/close door detector 333 may detect the opening and closing actions of the first door 200 and the second door 110 using a contact switch, a hall device, a magnetic sensor device, or the like.

The working principle of the refrigerator of the embodiment for maintaining the humidity of the sealed tub 310 is as follows: determining that the first door 200 and the second door 110 are both in a closed state, and acquiring the air humidity in the first storage space detected by the first humidity detection device 331 and the air humidity in the sealed tub 310 detected by the second humidity detection device 332; comparing the air humidity in the first storage space with the air humidity in the sealed tub 310; if the humidity of the air in the first storage space is greater than the humidity of the air in the sealed tub 310, the ventilation valve 341 is closed, and the vacuum pump 352 is started to evacuate the sealed drawer 300. When the humidity of the air inside the sealed tub 310 is higher than that of the refrigerating compartment, the ventilation valve 341 is opened and the vacuum pump 352 is started to ventilate the drawer 300. Air suction and/or air exchange time can be carried out according to preset time, and the air suction and/or air exchange device can be started and stopped according to the temperature.

The comparison of the air humidity in the first storage space and the air humidity in the sealed tub 310 and the control of the ventilation device 340 and the air-extracting device 350 can be performed by a controller.

In this embodiment, the humidity detection device is used to detect the humidity in the first storage space of the box 12 and the humidity in the sealing barrel 310, and the ventilation device 340 and the air-extracting device 350 are used to reduce the humidity of the sealing drawer 300. That is, when the drawer 320 is closed, the humidity in the drawer 300 is reduced by the vacuum dehumidifying technology, and the drawer 300 is kept in a dry state, which is beneficial to the storage of valuables.
