Stepless speed governing range hood

A technology for range hoods and stepless speed regulation, which is applied in the field of range hoods. It can solve the problems of heavy adjustment of the rectification plate and the inability to adjust the flow distribution and flow rate of the air inlet simultaneously, so as to improve the suction effect, improve the oil-gas separation effect, reduce the noise effect

Problems solved by technology

[0004] In this invention, the rectifying plate is designed as two rotatable rectifying plates, which can only adjust the distribution of the negative pressure area, and cannot simultaneously adjust the flow distribution and flow velocity of the air inlet; and the adjustment of the rectifying plates is relatively cumbersome

Embodiment Construction

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] Such as Figure 1 to Figure 8 As shown, the stepless speed range hood includes:

[0027] The smoke collecting hood 1 is connected under the chassis 15, and is formed by butt joints of the outer cover plate 11 and the inner cover plate 12, wherein the middle part of the inner cover plate 12 is provided to communicate with the volute inlet (not shown in the figure) of the range hood The oil fume suction port 13. The portion between the lowermost end of the inner cover plate 12 and the oil fume suction port 13 is in an arc shape.

[0028] The rectifying plate 2 is arranged in the middle of the inner cover plate 12 corresponding to the oil fume suction port 13, and is connected to the fume collecting hood 1 through the connecting plate 14; the oil fume suction port can be opened when the range hood is working, and the oil fume suction por...

Abstract

The invention relates to a stepless speed governing range hood which comprises a smoke collecting hood (1) and a flow rectification plate (2) which corresponds to an oil smoke suction inlet; a first air inlet (21) is formed between the edge of the left side of the flow rectification plate (2) and an inner side wall (12) of the smoke collecting hood (1); and a second air inlet (22) is formed between the edge of the right side of the flow rectification plate (2) and an inner side wall (12) of the smoke collecting hood (1). The stepless speed governing range hood is characterized in that a firstwind adjustment plate (31) corresponding to the first air inlet (21) and a second wind adjustment plate (32) corresponding to the second air inlet (22) are rotationally connected with the flow rectification plate (2); the inner side walls (12) of the smoke collecting hood (1) are arc-shaped in the longitudinal sections; and when the flow rectification plate (2) rotates from a smoke collecting hoodinlet to the oil smoke suction inlet, in the direction of the extension line of the flow rectification plate (2) in the longitudinal section, the distance between the edge of the left side or right side of the flow rectification plate (2) and the corresponding inner side wall (12) of the smoke collecting hood (1) is increased gradually. Stepless speed governing can be carried out on the oil smokesuction velocity, and the range of a negative pressure smoke drawing zone is changed, so that the oil smoke suction and discharge effects are improved; and the flow guide effect on an oil smoke flowis significant and the oil and gas separation effect is good.

Description

technical field [0001] The invention relates to the field of range hoods, in particular to a range hood with stepless speed regulation. Background technique [0002] Common household stoves usually have two burners on the left and right. During the cooking process, users often only use one side of the burner, and sometimes use both sides at the same time. If, in the actual cooking process, the user only uses the stove on the left to stir-fry, or uses the left side to stir-fry and the right side to steam rice, then for the range hood, the concentration and particles of oil fume on the left side are bound to be larger than those on the right side. Many, the left side is prone to oil fume escape. If the flow and suction on the right side of the range hood can be properly distributed to the left side at this time, the smoking effect will definitely be improved. [0003] CN201410543010.X discloses "A Top Suction Range Hood", which includes a smoke collecting hood, a first rectif...
