Detailed Description
The invention is described in further detail below with reference to the embodiments of the drawings.
Referring to fig. 1 to 3, a side-suction type range hood includes a housing 1, a panel 2 obliquely disposed at a front side of the housing 1, and a blower 3 disposed in the housing 1. The panel 2 is provided with an air inlet 21, a smoke baffle 4 is arranged at the air inlet 21, the upper end of the smoke baffle 4 is hinged with the panel 2 and can rotate relatively, and the lower end of the smoke baffle 4 is a free end, so that the air inlet 21 can be opened or closed. When opened, the smoke barrier 4 is in the first position; when closed, the smoke barrier 4 is in the second position.
The fan 3 runs at the lowest gear and low speed (the rotating speed of the motor of the fan 3 is 200r/min as described in the background art) by suspending the smoke baffle plate 4 at the front side of the panel 2 in the closed state, so that the air replacement function is realized. That is, at this time, the smoke baffle 4 is parallel to the panel 2 and located at the front side of the panel 2, and a gap d0 is provided between the smoke baffle 4 and the panel 2, preferably, d0.ltoreq.15 mm in order to prevent noise from being transmitted from the side of the air inlet 21 to the outside. Thus, the air in the kitchen can enter the interior of the range hood through the air inlet 21 and then be discharged to the outside, so that the air replacement is realized. By replacing the air, the PM2.5 reduction speed in the air is tens of times that of the air purifier, and the consumable does not need to be replaced.
In order to increase the space for air intake and prevent noise from being transmitted to the outside from the side surface of the air inlet 21, the projection of the smoke baffle 4 on the panel 2 covers the air inlet 21, so that the noise generated when the fan 3 works at a low speed cannot be transmitted from the front, and the overall noise of the range hood is reduced.
The distance between the upper edge of the smoke baffle 4 and the upper edge of the air inlet 21 in the inclined direction of the panel 2 is d1, the distance between the left edge of the smoke baffle 4 and the left edge of the air inlet 21 is d2, the distance between the right edge of the smoke baffle 4 and the right edge of the air inlet 21 is d3, and the following conditions are satisfied by the above parameters: d1, d2 and d3 are all more than or equal to 6mm, and d1/d0, d2/d0 and d3/d0 are all more than or equal to 0.4. Thus, the noise radiated from the inside of the range hood into the kitchen must be reflected once on the smoke baffle 4, thereby reducing the dB value of the noise.
The distance between the lower edge of the smoke baffle 4 and the lower edge of the air inlet 21 of the panel 2 in the inclined direction of the panel 2 is not more than 15mm, and the noise is increased due to the excessive distance.
The back of the panel 2 facing the inside of the shell 1 is provided with a back plate 5, and the back plate 5 can be adhered and fixed with the panel 2. Referring to fig. 4 and 5, the back plate 5 includes a plate body 51, and a long-strip-shaped inlet 52 corresponding to the air inlet 21 of the panel 2 is formed in the middle of the plate body 51, and the positions on the left and right sides of the inlet 52 on the plate body 51 are respectively recessed in a direction away from the panel 2 to form a profiling 53, wherein the recess height of the profiling 53 is h, and h < d0. Thereby, reflection of noise is formed between the profiling 53 and the smoke baffle 4 a plurality of times, thereby enhancing attenuation of noise.
In order to facilitate the rotation of the smoke baffle 4, the range hood further comprises a driving mechanism 6, and the driving mechanism 6 can adopt various existing driving mechanisms. As shown in the present embodiment, referring to fig. 6, the driving mechanism 6 includes a motor 61, a transmission mechanism, and a rotating arm 63 disposed on the back surface of the back plate 5, a first end of the rotating arm 63 is connected to the back surface of the back plate 5, and a second end of the rotating arm 63 passes through the inlet 52 of the back plate 5 and the air inlet 21 of the front plate 2 to be connected to the back surface of the smoke baffle 4. The output shaft 611 of the motor 61 extends transversely, the transmission mechanism comprises a bracket 621 and a connecting rod 622, one end of the output shaft 611 is fixedly connected with one end of the bracket 621, one end of the bracket 621 is rotatably connected with one end of the connecting rod 622, and the other end of the connecting rod 622 is rotatably connected with a third end of the rotating arm 63 between the first end and the second end. Preferably, the bracket 621 may have a U-shape, and the output shaft 611 and the link 622 are respectively connected to one arm of the U-shape. Thus, when the motor 61 is operated, the output shaft 611 drives the bracket 621 to rotate, so that the bracket 621 drives the connecting rod 622 to rotate, thereby driving the rotating arm 63 to rotate, and the smoke barrier 4 can rotate relative to the panel 2 to open or close the air inlet 21, see fig. 1 and 7. By the cooperation of the length and the rotation angle of the rotation arm 63, the smoke baffle 4 can be suspended on the front side of the panel 2 when closed.
The driving mechanism 6 is provided at one of the left and right sides of the smoke barrier 4, and the other side is provided with a driven mechanism 7, which may have only one member such as a rotating arm 63 of the driving mechanism 6.
