Detailed Description
The invention is further described below with reference to the accompanying drawings and examples.
Referring to fig. 1-4, the side-suction type range hood with the openable smoke barrier comprises a controller 1, a main motor, a rotating shaft 2, a driving mechanism 3, a smoke barrier 4 capable of being automatically opened and closed, a glass panel 5 and a driving motor 6, wherein the glass panel 5 is arranged on the outer side of a range hood main body, the smoke barrier 4 is connected with the driving mechanism 3, the controller 1 is connected with the driving motor 6 in the driving mechanism 3, and the rotation speed and the rotation direction of the driving motor 6 are controlled to control the operation of the whole driving mechanism 3, so that the automatic opening and closing of the smoke barrier 4 are controlled.
Specifically, the smoke baffle 4 is connected with the driving mechanism 3 through the rotating shaft 2, the rotating shaft 2 is fixedly connected with the smoke baffle 4, the rotating shaft 2 is of an S-shaped structure, the end part (namely the part connected with the smoke baffle 4) of the rotating shaft 2 is lengthened, and the lengthened length of the end part is preferably 10-20mm.
The controller 1 is also connected with a main motor, and the main motor is used for controlling the air quantity gear adjustment of the range hood. In conclusion, the controller 1 can synchronously control the main motor and the driving motor 6, so that the air quantity gear of the range hood and the specific opening and closing angle of the smoke baffle 4 can be specifically regulated and controlled respectively.
When the range hood is out of work, the smoke baffle 4 is closed, and the included angle between the smoke baffle 4 and the glass panel 5 is set to be 0 degree, namely, the smoke baffle 4 is parallel to the glass panel 5.
In the embodiment, the length of the connecting end of the rotating shaft 2 and the smoke baffle 4 is increased (by 10-20mm compared with the end of the rotating shaft of a common range hood), so that the smoke baffle 4 and the glass panel 5 are not on the same plane, the smoke baffle 4 and the glass panel 5 are not completely closed, a gap of 10-20mm is reserved between the smoke baffle 4 and the glass panel, and the risk that a user is pinched is avoided.
The upper end of the smoke baffle 4 is preferably provided with a section of inward bending structure 7, and the bending structure 7 faces the main body plane of the glass panel 5, so that the gap between the upper end of the smoke baffle 4 and the glass panel 5 is smaller under the condition of different opening and closing angles, and the range hood mainly enters air from the places where oil smoke is concentrated at the two side ends and the bottom end of the smoke baffle 4, reduces the oil smoke-free air sucked into the upper end of the smoke baffle 4, increases the negative pressure of the air inlet and improves the oil smoke extraction effect.
In summary, the bending structure 7 is designed to prevent smoke from leaking above the smoke barrier 4, thereby enhancing the smoke collection effect.
Preferably, the bending structure 7 includes, but is not limited to, the following two forms: curves and flaps, the curves of which are more gradual towards the plane of the body of the glass panel 5 (as shown in figure 2); the curve of the connecting part of the folding plate and the upper end of the smoke baffle plate 4 is more abrupt, and the folding plate directly inclines from the upper end of the smoke baffle plate 4 to the main body of the glass panel 5.
Preferably, the angle between the bending structure 7 and the main plane of the smoke baffle 4 is set to be 90-150 degrees.
As shown in fig. 5, when the range hood of this embodiment works, a user can select different gears according to the situation of oil smoke in a kitchen during the use of the range hood, and the intake air amount of the range hood also changes with the gear change selected by the user.
When a user operates the controller 1 to select a low gear, the controller 1 simultaneously controls the main motor and the driving motor 6 to be in the low gear, so that the air intake of the range hood is controlled to be smaller by the main motor, meanwhile, the driving motor 6 controls the driving mechanism 3 to be smaller at the current gear stroke, the opening angle of the smoke baffle plate 4 is smaller, the problem that the negative pressure of an air inlet is insufficient due to too large air volume when the opening angle of the smoke baffle plate 4 is relatively large is solved, meanwhile, an actual air inlet moves downwards to be closer to oil smoke, the situation that the loss occurs when the oil smoke is less and does not reach the air inlet is avoided, and the effect of absorbing the oil smoke is enhanced.
When a user gradually increases gears according to requirements, the controller 1 controls the main motor to control the range hood to gradually increase the air intake, and simultaneously the controller 1 controls the driving mechanism 3 to gradually increase the stroke along with the gear increase, so that the opening angle of the smoke baffle plate 4 is increased, and the range hood is ensured to have a large air intake when the air intake is required.
Preferably, the maximum air volume in the controller 1 corresponding to the high gear is 18-21m 3 Min, the opening angle of the smoke baffle plate is 70-90 degrees.
The large air volume corresponding to the middle gear in the controller 1 is 15-16m 3 Min, opening a corresponding angle of 20-70 degrees by the smoke baffle plate;
the minimum air quantity corresponding to the low gear in the controller 1 is 11-13m 3 Min, the opening angle of the smoke baffle plate is 0-20 degrees.
Preferably, the gear control of the controller of the embodiment can be further refined, and mainly the gear is subdivided into angle ranges corresponding to the air quantity and the opening of the smoke baffle in the middle gear.
The above description is only a preferred embodiment of the present invention, and should not be construed as limiting the scope of the present invention. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
