Detailed description of the invention
As shown in Figure 1 and Figure 2, a kind of tower air cleaner, including cartridge filter 11, cartridge filter installation cavity 12, it is positioned at the air inlet 13 of cartridge filter installation cavity 12 sidepiece circumference and is positioned at the air outlet 2 of cartridge filter 11 end, being wind chamber 3 between air outlet 2 and cartridge filter 11 end.Motor 41 and centrifugal wind wheel 42 it is provided with in wind chamber 3, centrifugal wind wheel 42 is under the driving of motor 41, the gas of the center throws away to the periphery, defines negative pressuren zone at its center, is positioned at the air flow inlet motion under the effect of draught head at its front end center of the gas of its front end.Wherein, the air flow inlet of centrifugal wind wheel 42 is towards cartridge filter 11 direction, and connected cartridge filter installation cavity 12 and wind chamber 3, the gas of centrifugal wind wheel 42 front end supplements in centrifugal wind wheel, and then negative pressuren zone is formed in cartridge filter 11 center, draught head inside and outside cartridge filter 11 makes the gas outside machine pass sequentially through air inlet 13 and cartridge filter 11, add to the negative pressuren zone of centrifugal wind wheel 42 front end endlessly, improve the filter area that cartridge filter effectively uses so that it is filtering material obtain comprehensive, utilize uniformly.
Central area between centrifugal wind wheel 42 and air outlet 2 is provided with wind scooper 5, forms air channel between the sidewall in wind scooper 5 and wind chamber 3, and air outlet 2 is arranged in the end face of air purifier in the form of a ring and connects with air channel.Wherein, the sidewall in wind chamber can be the medial wall of machine shell, it is also possible to be the medial wall of the cartridge that wind intracavity is arranged.Air-flow is after the air stream outlet of centrifugal wind wheel 42 throws away to the periphery, flow through air channel, air purifier is flowed out afterwards from air outlet 2, a series of processes flowed out from the air stream outlet of centrifugal wind wheel 42 after flowing through air inlet 13 in conjunction with said flow, and then complete air-flow circulation in whole air purifier.
Preferably, wind scooper 5 is provided with the gap of no more than 30 millimeters between the rear end of centrifugal wind wheel 42 one end and centrifugal wind wheel 42.As the horizontal cross-section in wind chamber have employed square, the non-circular shapes such as triangle, or assembling deviation, foozle etc., make the air stream outlet of centrifugal wind wheel 42 to the distance of wind chamber 3 sidewall uneven, and actually centrifugal wind wheel 42 itself is also difficult to ensure that it is uniform to the air-out of surrounding, factors above all can cause the air pressure imbalance of wind scooper 5 surrounding, affect the air output operation simultaneously to complete machine and bring vibrations and noise, above-mentioned gap then contributes to balancing above-mentioned draught head, the gas making air pressure higher position can be supplemented to air pressure lower by this gap, reduce vibrations and noise.Further, through hole also can be set on the rear end of centrifugal wind wheel, this gap the most through and the region of centrifugal wind wheel front end, the air-flow that a small amount of part inherent filtration cylinder 11 is moved to centrifugal wind wheel 42 direction directly enters in this gap by this through hole under motional inertia, wind intracavity hence into centrifugal wind wheel 42 rear end, and without the leaf area by centrifugal wind wheel 42, to improve the efficiency of air current flow in body.It is pointed out that the instability due to centrifugal wind wheel 42 motion itself and deviation, the gap not less than 5 millimeters, it is possible to decrease clash into the risk of wind scooper 5.And the distance in this gap is non-is the bigger the better, when clearance distance is more than 30 millimeters, air-flow throws away the flowing of backward surrounding from centrifugal wind wheel 42, collision is after the sidewall of wind chamber 3 under the effect of resilience force, and a part of air-flow keeps spiral to move upward, and another part air-flow the most inwardly springs back in this gap, drift above centrifugal wind wheel 42, define sinuous flow, impact wind scooper 5 and centrifugal wind wheel 42, increase vibrations and noise.It addition, the gas of destruction 5 weeks side air pressure higher positions of above-mentioned wind scooper is supplemented to the motor process of air pressure lower by the sinuous flow formed in this gap by this gap.Therefore, wind scooper near be not more than between centrifugal wind wheel one end and the rear end of centrifugal wind wheel the gap of 30 millimeters be beneficial to air mass stable drift in this gap, it is to avoid form sinuous flow, to reach above-mentioned technique effect.Meanwhile, this gap increases the increase that also will result in wind chamber 3 height, on the one hand increases the height of complete machine, has on the other hand elongated the length in airflow machine body-internal-circulation path, and then has improve windage, has increased the load of motor.Secondly, in the case of being fixed on wind scooper 5 at motor 41, still it is suspended to below wind scooper in being either placed in wind scooper, by increase motor go out shaft length or the length of motor rear end fixed component, and then the distance of centrifugal wind wheel and bearing will be increased, affect the stability that centrifugal wind wheel runs.
Wind scooper 5 includes the first wind-guiding section 51, and the first wind-guiding section 51 radial dimension near air outlet 2 one end is not less than the radial dimension of the other end, and the horizontal section area in the air channel at the i.e. first wind-guiding section 51 place gradually tapers up to air outlet 2 direction from centrifugal wind wheel 42.The air-flow flowed out from centrifugal wind wheel 42 the most helically rises shape, the air flow outlet of centrifugal wind wheel 42 defines the spiral district of air-flow to certain area above it, but air-flow is the collision impact of other parts in wind chamber sidewall and air channel, and air-flow occurs under the effects such as friction therewith, the airflow direction of certain area below air outlet 2 is made not have good concordance, forming sinuous flow district, the air mass in sinuous flow district, under the promotion of the air mass in spiral district, flows out from air outlet 2.Now, owing to the first wind-guiding section 51 limits the scope of air-flow horizontal looseness in air channel, and then improve the order of air mass in sinuous flow district.Further, owing to the horizontal section area in the air channel at the first wind-guiding section 51 place gradually tapers up to air outlet 2 direction from centrifugal wind wheel 42, improve the air-flow velocity near air outlet 2, on the one hand, the order of air mass in raising sinuous flow district, reduces vibrations and noise the most further, on the other hand, increase the air-flow velocity from air outlet 2 blowout, be conducive to being formed larger range of circulation of air flow in room, improve the efficiency of body outer circulation.Additionally, air channel is bigger near the radial distance of the radial direction of centrifugal wind wheel 42 one end, increase the fraction from the bounce-back of wind chamber sidewall and impact the wind scooper 5 distance near centrifugal wind wheel 42 one end, be conducive to this fraction to be buffered, it is to avoid directly to impact wind scooper and produce significant shock.Owing to the horizontal section area in the air channel at the first wind-guiding section 51 place gradually tapers up to air outlet 2 direction from centrifugal wind wheel 42, air-flow has been formed about higher air pressure in the air channel at the first wind-guiding section 51 place near air outlet 2, the imbalance of air pressure the most more highlights, the gap that wind scooper 5 is arranged between the rear end of centrifugal wind wheel 42 one end and centrifugal wind wheel 42 can the above-mentioned draught head of active balance, it is to avoid owing to draught head excessive near air outlet 2 brings excessive vibrations and noise.It is pointed out that can be by employing wind chamber sidewall in the way of central reduction, the air channel structure that the horizontal section area in the air channel forming the first wind-guiding section place gradually tapers up to air outlet direction from centrifugal wind wheel.Preferably, the height of the first wind-guiding section 51 is 40 millimeters to 90 millimeters.When the height of the first wind-guiding section 51 is less than 40 millimeters, part will flow out directly from air outlet 2 before not colliding the first wind-guiding section 51 during the gas flow sideways of wind chamber sidewall bounce-back, causing the first wind-guiding section 51 too short and the air mass in sinuous flow district can not play preferable arrangement effect, the effect that wind gathering simultaneously is accelerated is the most undesirable.When the height of the first wind-guiding section 51 is more than 70 millimeters, on the one hand increase the height of complete machine, on the other hand elongated the length in airflow machine body-internal-circulation path, and then improve windage, increased the load of motor.The sidewall of the first wind-guiding section 51 and the angle of horizontal plane are 45 ° to 70 °, it should be noted that, the sidewall of the first wind-guiding section 51 is the plane tilted or cambered surface, and above-mentioned angle refers to that the two ends up and down of the longitudinal section of the sidewall to the first wind-guiding section 51 carry out line, this line and the angle of horizontal plane.When this angle is less than 45 °, owing to the sidewall draft angles of the first wind-guiding section 51 is spent greatly, will result in impact and create the momentum to centrifugal wind wheel 42 direction to the air-flow bounce-back of the sidewall of the first wind-guiding section 51, opposing with overall airflow direction, affect cycle efficieny, additionally, angle of inclination is excessive causes air mass to create wind gathering acceleration effect drastically in this section of air channel, not only increase windage, and affect the stability of complete machine, cause vibrations and noise；When this angle is more than 70 °, wind gathering acceleration effect will significantly reduce.Further, the whole height of wind scooper 5 is H1, and the vertical difference in height of the front end of air outlet 2 to centrifugal wind wheel 42 is H2, wherein, 0.3≤H1/H2≤0.7.As H1/H2 ＜ 0.3, in the case of between wind scooper 5 and centrifugal wind wheel 42, gap holding is constant, the longitudinal size of centrifugal wind wheel 42 is bigger, the i.e. size of its air stream outlet is bigger, accordingly, its air output is higher, relative, air channel under this parameter sets is shorter, will affect wind scooper 5 to the guiding finishing effect of sinuous flow and wind gathering acceleration effect；As H1/H2 ＞ 0.7, in the case of between wind scooper 5 and centrifugal wind wheel 42, gap holding is constant, the longitudinal size of centrifugal wind wheel 42 is less, the i.e. size of its air stream outlet is less, accordingly, its air output is relatively low, and relative, air channel under this parameter sets is longer, and arranging long air channel in the machine of low air output will affect the efficiency of machine body-internal-circulation undoubtedly.
In the present embodiment, the horizontal section area in the air channel at the air flow outlet place of centrifugal wind wheel 42 is S1, the wind scooper 5 horizontal section area near the air channel at place, centrifugal wind wheel one end is S2, the wind scooper 5 horizontal section area near the air channel at air outlet place is S3, wherein, S1≤S2, and S3 ＜ S2.Air channel has sequentially formed the shape tapered into again after becoming larger between the air stream outlet of centrifugal wind wheel 42 to air outlet 2.Wherein, S1≤S2, this section of air channel is in expansion shape, reduce the windage of the air flow outlet of centrifugal wind wheel 42, make centrifugal wind wheel air-out more smooth and easy, simultaneously as horizontal section area is bigger, the mean flow rate of this section of air channel air-flow is relatively low, and the gas of 5 weeks side air pressure higher positions of the most above-mentioned wind scooper is supplemented to the motor process of air pressure lower by the gap between wind scooper 5 and centrifugal wind wheel 42；S3 ＜ S2, this section of air channel is contraction-like, produces the wind gathering acceleration effect of air-flow, improves the air velocity at air outlet 2 so that air-flow forms larger range of body outer circulation.Further, the horizontal section area of the air purifier end face at air outlet 2 place is S4, wherein, 0.1≤S3/S4≤0.6.In tower air cleaner, air output is affected by multiple factors, and wherein, the horizontal section area of air purifier end face is directly related with the sectional area in air channel, and the sectional area in air channel serves conclusive impact to air output.The horizontal section area of air purifier end face is the biggest, certain at motor speed, in the case of wind speed is certain, then air output is the biggest, produce vibrations and noise in order to avoid forming bigger air pressure in wind chamber 3, then require that the wind scooper 5 horizontal section area near the air channel at air outlet place is the biggest.On the other hand, the wind scooper 5 horizontal section area near the air channel at air outlet place is the most not the bigger the better, as excessive in air outlet 2, S3/S4 ＞ 0.6, will result in the flow velocity at air outlet 2 and reduces, and affects the efficiency of body outer circulation.Above-mentioned parameter scope will obtain between multiple indexs such as air output, body outer circulation efficiency, vibrations and noise and preferably balance and configure.It addition, as excessive in air outlet 2, the area of panel assembly 6 will reduce accordingly, not only have impact on the upper surface aesthetic property of shell, be also inconvenient for user operation.
