Hereinafter, the second ventilation port 206 is described by taking a damper 901 as an example.

Referring to fig. 9, it will be appreciated that the damper 901 of one embodiment is rotatably disposed within the second ventilation opening 206, and in particular, one side of the damper 901 is provided with a rotation axis about which the damper 901 rotates. The third ventilation pipe 703 is provided with a triggering portion 902, and in the process of closing the second door body 103, the triggering portion 902 is close to the air door 901, and then abuts against and pushes the air door 901 to rotate until the air door 901 rotates to an open position, so that the second ventilation opening 206 is opened. The second vent 206 is flush with or recessed from the front side of the septum 201, and the trigger 902 is a convex structure, which allows the trigger 902 to enter the second vent 206, thereby causing the damper 901 to rotate to the open position.

It can be appreciated that a torsion spring may be sleeved on the rotating shaft, when the second door body 103 is opened, the trigger portion 902 moves towards the outside of the second air vent 206, and the air door 901 is reset under the action of the torsion spring, that is, the air door 901 rotates to a closed position, so as to close the second air vent 206.

It can be understood that the trigger portion 902 plays a limiting role, and can prevent the air door 901 from being automatically closed, so as to ensure normal refrigeration. And the trigger portion 902 extends into the second air vent 206, so that air flow can be better guided from the second air vent 206 into the third air vent 703.

Note that the damper 901 may be driven to rotate by a motor. For example, when the trigger 902 approaches the damper 901, the controller can drive the damper 901 to rotate to the open position by receiving a corresponding sensing signal and controlling the motor to operate. When the trigger portion 902 is far away from the air door 901, the controller can receive corresponding induction signals and control the motor to act, so that the air door 901 is driven to rotate to the closed position.

Referring to fig. 10, it will be appreciated that the damper 901 of the other embodiment includes two door portions 1001, and both door portions 1001 are rotatably disposed in the ventilation opening, specifically, one side of each door portion 1001 is provided with a rotation axis about which the door portion 1001 rotates. The two door portions 1001 can abut against each other to jointly close the ventilation opening, and the trigger portion 902 can push the two door portions 1001 to rotate. The trigger portion 902 is correspondingly provided with two limiting stop bars 1002, and each limiting stop bar 1002 corresponds to one door portion 1001 respectively, that is, each limiting stop bar 1002 pushes one door portion 1001 to rotate respectively. By providing two gate portions 1001, each gate portion 1001 is smaller in width, so that the radius of rotation of the gate portion 1001 is reduced, the tangential movement stroke of the end points of the gate portion 1001 is shortened, internal stress is reduced for the component, and the gate portion 1001 is more reliable and is also quieter.

Referring to fig. 11, it will be appreciated that the damper 901 of another embodiment is slidably disposed in the second ventilation opening 206, the side wall of the first air duct member 402 is provided with a sliding channel 1106, and the damper 901 is disposed in the sliding channel 1106. The first air duct piece 402 is further provided with a limiting rib 1101, the limiting rib 1101 is located at the end portion of the sliding channel 1106, and a reset spring 1102 is arranged between the limiting rib 1101 and the air door 901. During the closing of the second door body 103, the trigger portion 902 urges the damper 901 to retract into the slide passage 1106, the damper 901 urges the return spring 1102 to compress, the damper 901 stays in the open position, and the second ventilation opening 206 is opened. The trigger 902 abuts against the damper 901, preventing the damper 901 from protruding.

When the second door body 103 is opened, the trigger portion 902 moves out of the second air vent 206, and the air door 901 is reset under the action of the reset spring 1102, that is, the air door 901 slides to the closed position, so as to close the second air vent 206.

Referring to fig. 11, it can be understood that the trigger portion 902 includes a connection section 1103 and a bending section 1104, the connection section 1103 is disposed in the front-rear direction, one end of the bending section 1104 is connected to the rear end of the connection section 1103, and the other end protrudes from the connection section 1103 toward the left side of the connection section 1103. The second ventilation opening 206 is directed to the right, the damper 901 slides in the front-rear direction, and the damper 901 is provided with a projection 1105, and the projection 1105 extends from the right side of the damper 901 to the right to form a structure capable of abutting against the bending section 1104. And the bump 1105 is located behind the front side of the damper 901, i.e., the front side of the bump 1105 and the front side of the damper 901 define a recess that can accommodate the bending section 1104. When the second door body 103 is closed, the trigger portion 902 moves backward, the bending section 1104 enters into the concave position, and pushes the protruding block 1105 to move backward, so as to drive the air door 901 to retract backward, and further open the second air opening 206.

In the embodiment shown in fig. 11, the air door 901 can be completely accommodated in the sliding channel 1106 without blocking the air flow passing through the second air opening 206, so that the resistance of the air flow is smaller, and the air flow is smoother. In addition, due to the bump 1105 and the concave portion, the bending section 1104 can avoid the air flow passing through the second air vent 206, so that the resistance of the air flow is smaller, and the air flow is smoother. In addition, one side of the connecting section 1103 facing away from the second air vent 206 is inclined, specifically, gradually inclined rightward along the direction from back to front, so as to guide the air flow into the third air vent 703, and reduce energy loss caused by turning the air flow.

Referring to fig. 12, it can be understood that the refrigerator further includes a sensor 1201, and the sensor 1201 is used to detect the position of the first door 102 or the second door 103.

It will be appreciated that in some embodiments, the sensor 1201 may be a pressure sensor 1201 or a travel switch, and when the damper 901 is in the open position, the damper 901 abuts the sensor 1201, thereby enabling a signal to be obtained that the damper 901 is in the open position for corresponding control.

When the first door body 102 or the second door body 103 is closed, the triggering part 902 on the first door body 102 or the second door body 103 pushes away the air door 901 to form a communication air duct, the first door body 102 or the second door body 103 presses the sensor 1201, the system receives a signal, and judges that the first door body 102 or the second door body 103 is closed, the fan 405 is controlled to be opened, and cold air is blown out along the complete air duct; when the first door 102 or the second door 103 is opened, the air door 901 is closed, the air duct is in a sealed state, the switch of the sensor 1201 is released, the system receives a signal, and the first door 102 or the second door 103 is judged to be opened, so that the fan 405 is controlled to stop rotating, and no cold air is blown out. It should be noted that, when the first door 102 or the second door 103 is opened, the purpose of reducing the leakage of the cold air is achieved by controlling the fan 405 to stop working and sealing the air duct through the damper 901. According to the above logic, the first door 102 or the second door 103 is closed to perform air blowing and cooling, and the first door 102 or the second door 103 is opened without leakage of cool air.

It will be appreciated that in other embodiments, the sensor 1201 may also be an ultrasonic ranging sensor 1201, a laser ranging sensor 1201, an infrared ranging sensor 1201, or the like.

It should be noted that, the solution of the embodiment of the present utility model may also be applied to a refrigerator with a single door, where the air supply assembly may be disposed on a side wall of the refrigeration compartment.

The embodiments of the present utility model have been described in detail with reference to the accompanying drawings, but the present utility model is not limited to the above embodiments, and various changes can be made within the knowledge of one of ordinary skill in the art without departing from the spirit of the present utility model.
