Abstract
The utility model provides a muting wind channel of an air purifier. The air purifier is characterized in that a centrifugal-turbine-type wind rotor with an axial wind inlet is arranged on an output shaft of a wind rotor motor of the air purifier and is positioned in a wind channel casing; the wind inlet of the wind rotor corresponds to a wind inlet of the wind channel casing; a wind outlet of the wind channel casing is connected with a wind outlet of the air purifier; the wind channel is formed by a space between the periphery of the wind rotor and the inner wall of the wind channel casing; the left edge, which corresponds to the wind outlet of the wind channel casing, of the wind channel has minimum sectional area; the sectional area of the wind channel is gradually increased from the left edge corresponding to the wind outlet of the wind channel casing along the direction of the periphery of the wind rotor until the right edge, which corresponds to the wind outlet of the wind channel casing, of the wind channel has maximum sectional area. Noise of air passing through the wind channel can be decreased, and the volume of air passing through the wind channel can be improved.
Description
Technical field
The utility model belongs to a kind of Domestic environment-protection equipment, relates in particular to the air flue structure of Household Air Purifier.
Background technique
Household Air Purifier is to utilize wind wheel to filter the air output after purifying again by carrying behind indoor air intake air channel through filter assemblies.
Household Air Purifier requires high air output and low noise, and air output and noise index are subject to the impact of a lot of structural factors, and wherein air flue structure is very large to air output and noise Index Influence.
The model utility content
The utility model provides a kind of air cleaner quiet air channel, its objective is and solves the shortcoming that prior art exists, and makes reduce the noise of the air that passes through air channel and improve by the air quantity of the air in air channel.
The utility model solves the technological scheme that its technical problem adopts:
The quiet air channel of air cleaner, it is characterized in that: be provided with a wheeled wind wheel of centrifugal vortex with air inlet through hollow shaft mouth on the output shaft of the wind wheel motor of air cleaner, wind wheel is contained in an air channel housing, the corresponding setting of intake grill that the intake grill of wind wheel is set with the air channel housing, the exhaust outlet of air channel housing is connected with the air cleaner exhaust outlet, formation air channel, space between wind wheel periphery and air channel inner walls, the sectional area in air channel is in the left hand edge place of the exhaust outlet corresponding to air channel housing minimum, the sectional area in air channel is started to increase gradually along the peripheral direction of wind wheel by the left hand edge place of the exhaust outlet corresponding to the air channel housing, until the sectional area in air channel is in the right edge maximum of the exhaust outlet corresponding to the air channel housing.
Usefulness of the present utility model is:
The sectional area of air channel of the present utility model housing is increased along the peripheral direction of wind wheel gradually by the exhaust outlet left hand edge place of air channel housing, until the exhaust outlet right edge of air channel housing reaches maximum, the blast that this design forms when wind wheel rotates is in the exhaust outlet left hand edge place of air channel housing maximum, thereby form a resistance barrier of air, the derivation exhaust outlet of keeping watch, and can avoid compressed by the air in wind wheel suction air channel, thereby under same wind speed round, than sectional area, do not have the air quantity in vicissitudinous air channel large, and volume of air enlarges, the noise of avoiding air compressing to produce in air channel.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the utility model External view;
Fig. 2 is the External view of another angle of the utility model.
Embodiment
" left and right " in this patent claim is for convenience, its implication is, the observer is in the angle in Fig. 1, also by the angle of outwards observing within the air cleaner casing, at this moment close observer's is air channel housing 4, cabinet panel 1 successively, and at this moment wind wheel 3 sense of rotation are counterclockwise.
As shown in Figure 1 and Figure 2, the quiet air channel of air cleaner of the present utility model is arranged on the cabinet panel 1 of air cleaner, is positioned at casing, has air intake grid 11 on cabinet panel 1.There is a wind wheel motor 2, be provided with a wheeled wind wheel 3 of centrifugal vortex with air inlet through hollow shaft mouth on the output shaft of wind wheel motor 2, in the air intake grid 11(figure on the tight-lipped subsides cabinet panel 1 of the air inlet through hollow shaft of wind wheel 3, the air inlet through hollow shaft mouth of wind wheel 3 is not covered and shows by motor).
The wheeled wind wheel 3 of so-called centrifugal vortex is that the intermediate circumference at two annular turbine sidewalls 31 is evenly equipped with some wind wheel blades 32.(in figure annular turbine sidewall 31 in wind wheel housing 4, the position that in figure, dotted line surrounds).During wind wheel 3 rotation, the air that the air inlet through hollow shaft mouth of process air intake grid 11 and wind wheel 3 enters can be by the centrifugal periphery that is thrown to wind wheel 3 of wind wheel blade 32.Wind wheel 3 is contained in an air channel housing 4, and air channel housing 4 is arranged on cabinet panel 1.The exhaust outlet 40 of air channel housing 4 is connected with the air cleaner exhaust outlet.
When motor 2 starting operation, wind wheel 3 is synchronous rotary thereupon also, outside air is sucked by the wind wheel 3 of High Rotation Speed, enters the intake grill of wind wheel 3 from air intake grid 11, under the effect of wind wheel 3 rotations, flow in the air channel outside wind wheel 3 peripheries, be rotated counterclockwise, route is as circular arc arrow line in figure, and the air channel from small to large of the sectional area within wind wheel housing 4 rotates, flow to the exhaust outlet 40 of wind wheel housing 4, discharge through the air cleaner exhaust outlet.
