[0063] The area of adjusting port 5 and the wind speed passing through adjusting port 5 are detected by damper control mechanism 4, according to the area of adjusting port 5 and the wind speed passing through the adjusting port 5, drive the adjusting assembly 21 movement, to adjust the air volume of entering the adjusting port 5.

[0064] Please refer toFigure 4 and Figure 5 The adjusting assembly 21 comprises a plurality of blade components 211, each of which is movably arranged to enclose the adjusting opening 5 between the blade components 211.

[0065] The movably arranged blade components 211 can open or close the adjusting opening 5.

[0066] Referring to Figure 4 and Figure 5 The blade components 211 comprise a first sector-shaped damper blade 2111, a second sector-shaped damper blade 2112, a third sector-shaped damper blade 2113 and a fourth sector-shaped damper blade 2114, and the two straight edges of the first sector-shaped damper blade 2111, the second sector-shaped damper blade 2112, the third sector-shaped damper blade 2113 and the fourth sector-shaped damper blade 2114 are at an angle of 90°.

[0067] The movably arranged blade components 211 can enclose the adjusting opening 5 between the blade components 211, and the square-shaped closed adjusting opening 5 can control the opening and closing of the damper.

[0068] Referring to Figure 1 , Figure 4 , Figure 5 and Figure 6 The damper opening and closing mechanism 2 further comprises a fixed wedge 22 movably arranged on one side of the blade components 211; the fixed wedge 22 comprises a first fixed wedge 221 and a second fixed wedge 222, and the first fixed wedge 221 and the second fixed wedge 222 are arranged at intervals.

[0069] A gear rotating disc 23 is in sliding contact with the blade components 211.

[0070] A first limiting groove 24 is located on and penetrates through the gear rotating disc 23, and the first fixed wedge 221 penetrates and slides in the first limiting groove 24.

[0071] A second limiting groove 25 is located on and penetrates through the gear rotating disc 23, and the second fixed wedge 222 penetrates and slides in the second limiting groove 25.

[0072] When the gear rotating disc 23 rotates, the first fixed wedge 221 slides in the first limiting groove 24, and the second fixed wedge 222 slides in the second limiting groove 25, thereby driving the blade components 211 to slide along the gear rotating disc 23.

[0073] The blade component 211 cooperates with the gear rotating disc 23 and the driving gear 31 through the fixing wedge 22. During rotation of the gear rotating disc 23, the blade component 211 moves in the first limiting groove 24 and the second limiting groove 25 through the first fixing wedge 221 and the second fixing wedge 222 respectively, so that the blade component 211 is closed in the middle in a square shape, thereby controlling the opening and closing of the adjusting port 5.

[0074] Please refer to Figure 6 and Figure 7 The first fixing wedge 221 comprises a fixing rod 2211 fixedly connected to one side of the blade component 211.

[0075] A sliding round head 2212 is fixedly arranged at the other end of the fixing rod 2211.

[0076] The sliding round head 2212 can be limited to slide in the third limiting groove, so as to prevent the first fixing wedge 221 from being separated.

[0077] Please refer to Figure 1 、 Figure 5 The clamping washer 6 is coaxially arranged on the side of the gear rotating disc 23 away from the blade component 211, and is rotationally connected to the gear rotating disc 23. The third limiting groove is arranged on the gear rotating disc 23, and the sliding round head 2212 can be limited to slide in the third limiting groove. The other side of the clamping washer 6 is fixedly arranged with the ventilation mechanism 1.

[0078] The ventilation pipe 11 and the gear rotating disc 23 are connected through the clamping washer 6, and the first fixing wedge 221 can be limited to slide in the third limiting groove of the clamping washer 6.

[0079] Please refer to Figure 1 The ventilation mechanism 1 comprises a ventilation pipe 11 arranged on the side of the clamping washer 6 away from the gear rotating disc 23.

[0080] A fan 12 is arranged on the other side of the ventilation pipe 11, and is used for conveying airflow. The fan 12 is powered by the power supply part of the refrigerator.

[0081] The airflow can be conveyed to the chamber of the refrigerator through cooperation of the ventilation pipe 11 and the fan 12.

[0082] Please refer to Figure 1 、 Figure 12 、 Figure 13 and Figure 14The damper control mechanism 4 includes a sensor 41, which includes a temperature and humidity sensor and a wind speed sensor. The sensor 41 is located on the side of the fan 12 away from the ventilation duct 11.

[0083] Sensor housing 42, which is mounted on the other side of sensor 41;

[0084] The damper control mechanism 4 detects the area of ​​the regulating port 5 and the passing wind speed through the sensor 41. When the temperature and humidity are higher than the set value, the sensor 41 sends a signal to the outside, thereby causing the fan 12 and the blade component 211 to shut down.

[0085] by Figure 12 For the initial process, adjustment port 5 is in the closed state;

[0086] In the first process, when the internal fruit and vegetable drawer is in a low humidity environment q1 (below 40%), the temperature and humidity sensor detects a low humidity environment. The stepper motor then starts working continuously, driving the shaft of motor 32 to rotate counterclockwise and causing the gear turntable 23 to rotate α1 degrees. The adjacent surfaces H1 and H2 of the first sector-shaped damper blade 2111 and the second sector-shaped damper blade 2112 continuously cooperate to perform a trajectory-changing translational movement based on the first fixed wedge 221 and the second fixed wedge 222. Figure 14 As shown, the first fixed wedge 221 and the second fixed wedge 222 are located at positions C1 and C2, respectively. The area of ​​the adjustment port 5 is opened to the maximum. The wind speed V of the fan 12 inside S1 is monitored by the wind speed sensor, thereby calculating the air volume Q3 of the room per unit time.

[0087] In the second process, as time increases, the humidity in the compartment continues to rise. When the internal fruit and vegetable drawer is in a medium humidity environment q2 (50%~70%), the temperature and humidity sensor transmits a signal indicating a medium humidity environment. The stepper motor spindle begins to rotate counterclockwise and drives the gear turntable 23 to rotate α2 degrees. During this period, the surface H1 of the first fan-shaped damper blade 2111 in the upper left corner and the surface H2 of the second fan-shaped damper blade 2112 in the upper right corner are always in a state of overlap and engagement. The blade component 211 continues to perform a biaxial translational movement, and at this time, if... Figure 13 As shown, the first fixed wedge 221 and the second fixed wedge 222 are located at positions B1 and B2, the area of ​​the regulating port 5 is S2, and the fan speed is V, so the air volume of the room Q2 per unit time can be calculated.

[0088] The third process, the humidity of the interval chamber continues to increase over time, when the humidity of the internal fruit and vegetable drawer is in a high humidity environment q1 (80%~90%), at this time the temperature and humidity sensor detects that the internal humidity is too high, stops the rotation of the stepping motor to close the adjusting port 5, and the blade part 211 is completely closed, the passing area is 0, that is, the air volume passing through is Q1=0, and the adjusting port 5 is in a completely closed state, as shown in Figure 12 The first fixed wedge 221 and the second fixed wedge 222 are located at positions A1 and A2.

[0089] In this way, the air door control mechanism 4 can adjust the air volume according to real-time feedback, accurately control the temperature and humidity of the internal fruit and vegetable drawer, and ensure that the internal fruit and vegetable drawer environment is always in an ideal state, avoiding problems such as excessive ventilation or excessive humidity.

[0090] Please refer to Figure 4 The first limiting groove 24 is arranged in a ring array around the shaft of the gear turntable 23, and the first limiting groove 24 is equidistantly provided with four; and / or,

[0091] The second limiting groove 25 is radially distributed around the shaft of the gear turntable 23 and located between the two first limiting grooves 24, and the second limiting groove 25 is equidistantly provided with four; and / or,

[0092] The third limiting groove is arranged in a ring array around the shaft of the clamping gasket 6 and corresponds to the position of the first limiting groove 24.

[0093] By arranging the first limiting groove, the second limiting groove, and the third limiting groove, the adjusting assembly 21 can move under the limiting sliding of the fixed wedge 22, so as to achieve the purpose of adjusting the adjusting port 5.

[0094] Please refer to Figure 1 and Figure 2 The power mechanism 3 comprises a driving motor 32, the driving motor 32 is fixedly installed on one side of the ventilation duct 11 close to the gear turntable 23, the other side of the driving motor 32 is fixedly connected with the driving gear 31, the driving gear 31 is in meshing transmission with the gear turntable 23, and the driving motor 32 can be a servo motor or a stepping motor.

[0095] The rotation of the driving gear 31 is driven by the accurate control of the servo motor or the stepping motor, and the size of the adjusting port 5 is accurately controlled through the meshing of the driving gear 31 and the gear turntable 23.

[0096] A refrigerator, wherein the refrigerator is provided with the air door structure in the technical scheme.

[0097] Working principle:

[0098] First, the driving motor 32 drives the driving gear 31 to do the fixed shaft circumferential motion, the gear disc 23 is driven to rotate by engaging with the driving gear 31, the blade part 211 is matched with the clamping washer 6 and the gear disc 23 through the fixed wedge 22, in the process of rotating the gear disc 23, the blade part 211 is slid in the first limiting groove 24 through the first fixed wedge 221 and is slid in the second limiting groove 25 through the second fixed wedge 222, so that the middle of the plurality of blade parts 211 is closed in a square, thereby controlling the size of the adjusting port. Then the fan 12 runs to transport fresh air to the room through the ventilation duct 11, so as to achieve the functions of air exchange and moisture retention in the room. At the same time, the sensor 41 calculates the existing air volume in the room through the damper area and the wind speed, when the temperature and humidity are higher than the average level, the sensor 7 sends a signal to the central control unit, so that the fan 12 and the precision control adjusting port 5 are closed, thereby accurately controlling the temperature and humidity level in the room.
