[0027] Reference Figures 1 to 6The side suction range hood of the embodiment of the present invention comprises a housing 100, a flap 200, a wind cabinet device 400 and a control device 500. The housing 100 has a smoke inlet 110, the flap 200 is adapted to the smoke inlet 110, the flap 200 is arranged at the smoke inlet 110, and the flap 200 is movably connected with the housing 100 through a push plate mechanism 300, the flap 200 can move relative to the housing 100 to open or close, and when the flap 200 is closed on the housing 100, the smoke inlet 110 can be blocked. The wind cabinet device 400 is arranged on the inner side of the flap 200, and has an air outlet 411 on the wind cabinet device 400, when the flap 200 is opened relative to the housing 100, the air outlet 411 faces downward so as to exhaust air downward. The control device 500 is disposed inside the housing 100, and is electrically connected to the wind cabinet device 400. The start and stop of the wind cabinet device 400 can be controlled by the control device 500. The push plate mechanism 300 is also electrically connected to the control device 500 so that its operation is controlled by the control device 500. In addition, a second fan (not shown in the figure) is also disposed inside the housing 100, and the second fan is also electrically connected to the control device 500.

[0028] When the user turns on the range hood, the push plate mechanism 300 operates to open the flap 200 relative to the box 100, and the second fan operates to suck in the smoke from the outside. After the flap 200 is opened relative to the box 100, the air outlet 411 moves to a downward position, the wind cabinet device 400 starts and exhausts air downward through the air outlet 411, so that a wind wall can be formed between the user and the pot. The wind wall can block the smoke and prevent the smoke from escaping to the user, protect the user's health, and optimize the user's experience. When the flap 200 is covered on the box 100, the wind cabinet device 400 can be hidden in the box 100 to prevent flying insects from entering the box 100, and make the overall appearance of the range hood more simple and beautiful.

[0029] In some embodiments, the control device 500 may also be disposed on the flap 200. In addition, a housing connected to the inner cavity of the housing 100 may be disposed on the top or other position of the housing 100, and the second fan may be disposed in the housing.

[0030] Specifically, refer to Figure 3The wind cabinet device 400 includes a wind cabinet shell 410 and a first fan 420. The wind cabinet shell 410 is connected to the inner side of the flap 200, and the wind cabinet shell 410 and the flap 200 together form a wind cavity 430. The bottom of the wind cabinet shell 410 has an air outlet plate 412, and the air outlet 411 is arranged on the air outlet plate 412. The first fan 420 is arranged in the air cavity 430, and the first fan 420 is electrically connected to the control device 500. The flap 200 is provided with an air inlet 210 connected to the air cavity 430. When the flap 200 moves and opens relative to the box body 100, the bottom surface of the air outlet plate 412 faces rearward and downward. When the first fan 420 is running, the outside air enters the air cavity 430 through the air inlet 210, and then is discharged through the air outlet 411, so that a wind wall can be formed.

[0031] The wind cavity 430 includes a first cavity section 431 and a second cavity section 432 which are connected. The first cavity section 431 is arranged on the upper side of the second cavity section 432. The air inlet 210 is connected to the first cavity section 431, and the air outlet 411 is connected to the second cavity section 432. The width of the second cavity section 432 gradually increases from top to bottom, and the thickness of the second cavity section 432 gradually decreases from top to bottom. Through this structure, the wind wall can have a sufficiently large width, and the airflow forming the wind wall has a sufficiently large flow rate, which is convenient for blocking smoke; the thickness of the lower section of the wind cabinet shell 410 gradually increases from bottom to top, so as to guide the smoke, so that the smoke flows along the wind cabinet shell 410 to the smoke inlet 110.

[0032] As a working mode of the range hood, a start button electrically connected to the control device 500 is provided on the box body 100. When the user presses the start button, the control device 500 controls the push plate mechanism 300 to operate to open the flap 200. When the flap 200 is opened, the control device 500 controls the operation of the first fan 420 and the second fan, so that the first fan 420 and the second fan can be started with one button, reducing the user's operation.

[0033] In order to detect whether the flap 200 has been opened, a detection member may be provided on the box body 100 or the flap 200, the detection member is located between the box body 100 and the flap 200, and the detection member is electrically connected to the control device 500. When the push plate mechanism 300 drives the flap 200 to move and open, the detection member may be triggered, and after being triggered, the detection member may send a trigger signal to the control device 500, and the control device 500 drives the first fan 420 and the second fan to operate after receiving the trigger signal. The detection member may be set as a limit switch, a proximity switch, or a photoelectric switch.

[0034] As another working mode of the range hood, two start buttons are provided. When the user presses the first start button, the control device 500 controls the push plate mechanism 300 and the second fan to operate. When the user presses the second start button, the first fan 420 can operate. When the user is not close to the pot for cooking, the user can choose not to start the first fan 420 to reduce energy consumption.

[0035] For the above two working modes, the start-up of the second fan can also be controlled by timing. When the user presses the start button, the push plate mechanism 300 operates, and after a set period of time, the second fan starts automatically.

[0036] Reference Figure 5 The push plate mechanism 300 includes a push plate motor 310, a first push rod 320, a second push rod 330 and a third push rod 340. The push plate motor 310 is disposed inside the box 100. One end of the first push rod 320 is fixedly connected to the output shaft of the push plate motor 310. One end of the second push rod 330 is rotatably connected to the other end of the first push rod 320 through a rotating shaft or a rivet. One end of the third push rod 340 is fixedly connected to the flap 200. The other end of the third push rod 340 is rotatably connected to the box 100 through a rotating shaft or a rivet. The other end of the second push rod 330 is rotatably connected between the two ends of the third push rod 340 through a rotating shaft or a rivet. With this structure, when the push plate motor 310 is running, the flap 200 can be driven to move so that the flap 200 is opened relative to the box 100 or covered on the box 100.

[0037] The third push rod 340 is U-shaped, and the other end of the second push rod 330 is rotatably connected to the bending part of the third push rod 340 through a rotating shaft or a rivet, so that the flap 200 has a sufficiently large opening angle.

[0038] In some embodiments, the push plate mechanism 300 may be composed of an electric push rod and a hinge, etc. The top of the flap 200 is rotatably connected to the box body 100 through a hinge, and the two ends of the electric push rod are respectively connected to the box body 100 and the flap 200, and the electric push rod is used to drive the flap 200 to rotate and open and close relative to the box body 100.

[0039] Reference Figure 7 In some embodiments, the wind cabinet device 400 further includes a baffle 440 located on the inner side of the flap 200 , and the baffle 440 is rotatably connected to the flap 200 via a pivot 450 .

[0040] Reference Figure 1 When the flap 200 is covered on the box body 100, the outer side of the flap 200 faces forward and downward; Figure 4 and Figure 6When the flap 200 is opened relative to the box body 100, the outer side of the flap 200 faces the front and upward. Accordingly, when the flap 200 covers the box body 100, the baffle 440 can rotate to abut against the flap 200 under the action of its own gravity, and the air inlet 210 can be closed through the flap 200 to prevent flying insects from entering the air cavity 430 through the air inlet 210; when the flap 200 is opened relative to the box body 100, the baffle 440 can rotate away under the action of its own gravity, and the baffle 440 is no longer abutted against the flap 200, so that the air inlet 210 can be opened to allow outside air to enter the air cavity 430.

[0041] Of course, the blocking piece 440 can also be rotatably connected to the wind cabinet housing 410 via the pivot 450 .

[0042] Preferably, a torsion spring (not shown in the figure) may be sleeved on the pivot 450, and a torsion arm at one end of the torsion spring abuts against the baffle 440, and a torsion arm at the other end of the torsion spring abuts against the flap 200 or the wind cabinet housing 410. When the flap 200 is closed on the box body 100, the baffle 440 may be pushed to rotate toward the flap 200 by the force of the torsion spring to ensure that the baffle 440 abuts against the flap 200. When the flap 200 is opened relative to the box body 100, the first fan 420 is operated to form a negative pressure in the air cavity 430, and air enters the air cavity 430. The combined effect of the airflow and the gravity of the baffle 440 can overcome the elastic force of the torsion spring, so that the baffle 440 rotates and no longer abuts against the flap 200.

[0043] In some embodiments, for the wind cabinet device 400, the wind cabinet shell 410 can be set as a closed shell, that is, the wind cavity 430 is only surrounded by the wind cabinet shell 410, and the inner cavity of the wind cabinet shell 410 is the wind cavity 430. The air inlet 210 can be set on the flap 200, and can also be set on the top of the wind cabinet shell 410.

[0044] To ensure smooth opening and closing of the flap 200, when the flap 200 is opened relative to the box body 100, there is a gap between the upper edge of the flap 200 and the box body 100. The gap is located above the wind cabinet shell 410, and the wind cabinet shell 410 has a certain thickness, which can guide and shield the smoke, and can make the flow path of the smoke away from the gap, avoiding the smoke from moving up to the gap, thereby optimizing the anti-smoke leakage effect of the range hood.

[0045] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
