As a further improvement of the technical solution of the present invention, the two side walls of the dry matter chamber are provided with pulleys, and the two sides of the drawer are provided with inclined slide rails for accommodating the pulleys, and the drawer slides along the inclined slide rails to close .

As a further improved technical solution of the present invention, the end of the inclined slide rail has a clearance to press the drawer and the dry matter chamber by the gravity of the drawer and the article itself stored in the drawer. .

As a further improved technical solution of the invention, the air duct is closed.

As a further improved technical solution of the present invention, the dry matter chamber and the damper baffle form a separate system and are not in communication with the refrigerating chamber.

As a further improved technical solution of the present invention, the dry matter chamber is ventilated by an assembly gap between the tub and the drawer.

Compared with the prior art, the dry matter chamber of the refrigerator of the present invention adopts a single damper structure, and when the dry matter room does not need to be ventilated, the dry seal of the dry matter chamber is achieved; when the dry matter chamber needs air intake and ventilation, it is guaranteed Good ventilation of the dry room.

 【detailed description】

Referring to FIGS. 1 and 2, the present invention discloses a refrigerator including a casing (not shown), a refrigeration cycle system 1, and a duct 2. The cabinet includes a refrigerating chamber 6 and a dry chamber 3, wherein the dry chamber 3 includes a tub 31 and a drawer 32 removably received in the tub 31. The tub 31 is provided with a dry chamber duct 33 that communicates with the duct 2 and a damper flap 34 that is mounted in the dry chamber duct 33. The refrigeration cycle system 1 includes a compressor 11, a condenser 12, a throttle element 13, and an evaporator 14. The refrigerator is further provided with a fan 4 located in the air duct 2, and the fan 4 is configured to blow air cooled and dehumidified through the evaporator 14 to the refrigerating chamber 6 and/or the dry object room. 3. The dry matter chamber 3 is substantially sealed, and the joint of the tub 31 and the drawer 32 is sealed by a sealing member 5 to be separated from the outside air. The dry matter chamber 3 is not provided with a wind damper.

The barrel body 31 has a substantially rectangular parallelepiped shape and includes a top wall 311, a bottom wall 312, two side walls, and a rear wall 313. In the illustrated embodiment of the invention, the dry room air duct 33 extends through the rear wall 313, and the damper flap 34 is mounted on the rear wall 313.

The drawer 32 is provided with a handle 321 which is an end surface 314 of the barrel 31 adjacent to the handle 321 . The sealing member 5 is a sealing strip and is disposed on the end surface 314 . Preferably, the sealing strip is a silicone sealing strip.

The two side walls of the dry matter chamber 3 are provided with pulleys 315. Both sides of the drawer 32 are provided with inclined slide rails 322 for accommodating the pulleys 315, and the drawers 32 are slid along the inclined slide rails 322 to close. When the drawer 32 is closed, sealing is performed by the sealing member 5.

The end of the inclined slide rail 322 is left with a clearance to press the drawer 32 and the dry matter chamber 3 against the gravity of the drawer 32 and the article itself stored in the drawer 32, and The sealing member 5 is used to ensure airtightness between the dry chamber 3 and the outside chamber.

Referring to Figure 2, the air duct 2 is closed. The air duct 2 is provided with a refrigerating compartment duct 21 that communicates with the refrigerating compartment 6, and the dryroom duct 33 is connected in parallel with the refrigerating compartment duct 21. A damper flap is not disposed between the front end of the dry matter chamber duct 33 and the fan 4. It should be noted that the "front end" indicated above is defined by the flow direction of air in the air duct 2, and the air closer to the fan is located at the front end.

The dry matter chamber 3 forms a separate system with the damper flap 34 and does not collide with the refrigerating chamber 6.

When used, the ventilation method of the refrigerator of the present invention is as follows:

After the damper flap 34 is opened, the air cooled and dehumidified is blown into the dry matter chamber 3 and/or the refrigerating chamber 6 through the blower 4. With the blowing of dry air, the dry matter chamber 3 is maintained at a positive pressure, and the ventilation of the dry matter chamber 3 mainly passes through two points: first, under positive pressure, through the barrel 31 and the drawer 32 The assembly gap between the two is ventilated; secondly, because the drawer 32 is naturally closed by the gravity of the stored objects in its own drawer, the dry matter chamber 3 is under positive pressure, between the drawer 32 and the dry chamber 3 The gap formed is ventilated.

Compared with the prior art, the dry matter chamber 3 of the refrigerator of the present invention adopts a structure that only has an air inlet damper and no air damper, which reduces the cost; at the same time, the air is exchanged through the gap, thereby solving the problem of the air exchange and the improvement of the air. The airtightness of the dry matter chamber 3 is described.

It should be noted that the above embodiments are only for explaining the present invention and are not intended to limit the technical solutions described in the present invention. Although the present specification has been described in detail with reference to the above embodiments, those skilled in the art It is to be understood that the invention may be modified or equivalently modified by those skilled in the art without departing from the scope of the invention.
