Abstract
The utility model provides an air channel structure of air purifier mainly includes shell, wind channel, aviation baffle, motor, motor support, wind wheel and air intake ring flange, the shell in set gradually aviation baffle, motor, wind wheel and air intake ring flange from top to bottom, the bottom surface of wind wheel sets up in the flange hole, the flange hole pore wall of air intake ring flange is towards the bellied curved surface of wind wheel. Air channel structure of air purifier avoided wind mutual interference or cancel each other out in the wind channel, thereby has reduced the striking of air and casing and reduced the noise that air purifier produced when the operation, also improved purification efficiency simultaneously.
Description
Technical field
The utility model relates to a kind of air purifier, especially a kind of air channel structure of air purifier.
Background technology
The variation of air quality and the multiple people of making of breathing problem start to pay attention to air quality, meet the need of market to reduce pollutants in air to the harm of human body, air purifier miscellaneous arises at the historic moment, vertical air eliminator takes up room little with it, air output is large and enjoy consumers, but in use also there is certain defect in vertical air eliminator: due to the intake of vertical air eliminator and air output large, cause air in air channel, clash into the noise of body larger, affect its result of use, also can cause another kind of pollution-noise pollution simultaneously.Trace it to its cause, because in the air channel of air purifier, the contact of air inlet ring flange and housing is right-angled corner, the hole wall of air inlet ring flange caves inward, cause in air channel, telling that the air of motion is mutually interfered and cancels out each other, increase the noise that air purifier operationally produces.Therefore a kind of noise of the faultiness design overcoming prior art is little and air purification efficiency is high air purifier is this area problem demanding prompt solution.
Summary of the invention
In view of this, the utility model is intended to the air channel structure proposing a kind of air purifier, to solve the technical problem that in prior art, air purifier noise is large.
For achieving the above object, the technical solution of the utility model is achieved in that
A kind of air channel structure of air purifier, comprise shell, air channel, wind deflector, motor, electric machine support, wind wheel and air inlet ring flange, wind deflector, motor, wind wheel and air inlet ring flange is disposed with from top to bottom in described shell, motor and electric machine support are installed between described wind deflector and wind wheel, described wind wheel is connected with motor by the output shaft of motor, the bottom surface of described wind wheel is arranged in flange hole, and the flange hole hole wall of described air inlet ring flange is the curved surface towards wind wheel projection.
Preferably, the curve forming described curved surface is circular arc.
Further, the radian of described circular arc is 30 °-170 °.
Preferably, the radian of described circular arc is 93 °.
Further, the junction of described shell and air inlet ring flange is grounded angle corners.
Preferably, the circle of described grounded angle corners and shell and air inlet ring flange upper surface is formed tangent.
Further, described grounded angle corners by fill silencing cotton shaping or with shell integrated injection molding.
Further, the axis of described air inlet ring flange and the central shaft of wind wheel are on the same line.
The utility model additionally provides a kind of air purifier, and the air channel structure of this air purifier adopts any one air channel structure above-mentioned.
Relative to prior art, the air channel structure of air purifier described in the utility model has following advantage:
The junction of air inlet ring flange and housing in air channel is that right-angled corner becomes grounded angle corners by the air channel structure of air purifier described in the utility model, the flange hole of the air inlet ring flange surface corresponding with wind wheel air outlet is the curved surface towards wind wheel projection by the curved design to lower recess, such air channel structure effectively avoids air mutually interferes or cancels out each other in air channel, decrease the shock of air and housing thus reduce the noise that air purifier operationally produces, simultaneously because the energy loss of air in air channel reduces, therefore air output also increases thereupon, and then improve the purification efficiency of air purifier.
Accompanying drawing explanation
Fig. 1 is the structural representation of the air channel structure of the air purifier described in the utility model embodiment.
Description of reference numerals:
1-shell, 2-air channel, 3-wind deflector, 4-motor, 5-electric machine support, 6-wind wheel, 7-air inlet ring flange, 8-curved surface, 9-grounded angle corners.
Detailed description of the invention
Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
As shown in Figure 1, a kind of air channel structure of air purifier, comprise shell 1, air channel 2, wind deflector 3, motor 4, electric machine support 5, wind wheel 6 and air inlet ring flange 7, wind deflector 3 is disposed with from top to bottom in shell 1, motor 4, wind wheel 6 and air inlet ring flange 7, motor 4 and electric machine support 5 are installed between wind deflector 3 and wind wheel 6, wind wheel 6 is connected with motor 4 by the output shaft of motor 4, it is outer in order to protect motor 4 that electric machine support 5 covers on motor 4, the bottom surface of wind wheel 6 is arranged in flange hole, the axis of air inlet ring flange 7 and the central shaft of wind wheel 6 are on the same line, the flange hole hole wall of air inlet ring flange 7 is the curved surface 8 towards wind wheel 6 projection.In order to reduce interference and the counteracting of wind in air channel 2 further, shell 1 and the junction of air inlet ring flange 7 are designed to grounded angle corners 9 by existing right-angled corner, the upper surface forming the circle of this grounded angle corners 9 and shell 1 and air inlet ring flange 7 is tangent, this grounded angle corners 9 and shell 1 together injection mo(u)lding.
The air purifier of above-mentioned air channel structure manufacture will be adopted to test under the experiment condition meeting standard GB/T 18801-2008, when the radian of circular arc be 30 °, CARD value is 130m
3during/h, noise during operation can be reduced to 46bB from 51dB, namely reduce the noise of 5dB; When the radian of circular arc be 170 °, CARD value is 200m
3during/h, noise during operation can be reduced to 51bB from 57dB, namely reduce the noise of 6dB; When the radian of circular arc be 93 °, CARD value is 500m
3during/h, noise during operation can be reduced to 53bB from 62dB, namely reduce the noise of 9dB.Visible, when the curve employing 30-170 degree circular arc of air inlet ring flange 7 flange hole hole wall curved surface 8, noise is reduced 5-9dB, decrease air mutually interfere in air channel 2 or cancel out each other, decrease the shock of air and shell 1 simultaneously thus reduce the noise that air purifier operationally produces.
In order to reduce noise further, grounded angle corners 9 is also shaping by filling silencing cotton at right-angled corner place.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
