Abstract
A kind of centrifugal blower, this centrifugal blower comprises motor (1), draught fan impeller (2), assembling support (3) and intake grill (4), motor (1) is installed on assembling support (3), draught fan impeller (2) is arranged on the output shaft of motor (1), described assembling support (3) is also provided with a U-shaped housing (5), described draught fan impeller (2) is placed in U-shaped housing (5) cavity, described intake grill (4) is fixedly installed on U-shaped housing (5), described U-shaped housing (5) is by the top plate (5.1) be installed in assembling frame (3), lower plywood (5.2) and a U-shaped cover (5.3) assemble.This centrifugal blower had both ensured that its volume met the limited space of air-conditioner set, and its fan efficiency is high, and wind is made an uproar little, easy accessibility.
Description
Technical field
The present invention relates to a kind of centrifugal blower being applied to air-conditioner set.
Background technique
In air-conditioner set ventilation system in the past, adopt has volute casing centrifugal blower fan more, one disclosed in Chinese patent CN203548339U has volute casing centrifugal blower fan to include spiral case, draught fan impeller, motor, and the inner flow passage of this spiral case comprises diffuser, the section of extending out, snail tongue and helicoid.Due in the closed box of air-conditioner set, limited space, and have volute casing centrifugal blower fan volume large, be not too applicable to being installed in the casing of air-conditioner set, therefore, have volute casing centrifugal blower fan to be replaced by without spiral case blower fan gradually.
The disclosed one of Chinese patent CN203130545U comprises slip ring, impeller, motor and fan supporter without spiral case blower fan, impeller is arranged in fan supporter, impeller is connected with the pto＝power take-off of motor by wheel hub, slip ring is independently fixed on the side plate of fan supporter, motor is fixed on the opposite side corresponding with side plate, air enters impeller from slip ring, flows out after impeller from support surrounding.This blower fan is not owing to having spiral case, and therefore volume is little, but there is ineffective problem.
Summary of the invention
The technical problem to be solved in the present invention is, provides a kind of centrifugal blower, and both ensured that its volume meets the limited space of air-conditioner set, and its fan efficiency is high, wind is made an uproar little, easy accessibility.
The present invention for solving the problems of the technologies described above provided technological scheme is: a kind of centrifugal blower comprises motor, draught fan impeller, assembling support and intake grill, motor is installed on assembling support, draught fan impeller is arranged on the output shaft of motor, it is characterized in that, described assembling support is also provided with a U-shaped housing, described draught fan impeller is placed in U-shaped shell cavity, and described intake grill is fixedly installed on U-shaped housing.
Described U-shaped housing is assembled by the top plate be installed in assembling frame, lower plywood and a U-shaped cover.
Draught fan impeller axle center is respectively L1 to the lateral separation of the sidewall of U-shaped housing air-flow pressurization starting point, and the fore-and-aft distance to U-shaped housing cambered surface is L2, to being L3, L1≤L2≤L3 with the pressurize lateral separation of relative another sidewall of the sidewall of starting point of U-shaped housing air-flow.
The sidewall of described U-shaped housing air-flow pressurization starting point is also provided with a guide plate.
This centrifugal blower is applied in air-conditioner set, and the U-shaped housing of this centrifugal blower is less than full spiral type spiral case centrifugal blower volume, can meet the space that air-conditioner set is limited; Owing to adopting said structure, U-shaped housing plays air-flow leading role, decreases the turbulent flow of air-flow in casing wedge angle, avoids casing other parts interior to the interference of air-flow, thus improves fan efficiency; Because U-shaped housing adopts Split type structure, easy accessibility.

Embodiment
Describe the present invention below in conjunction with accompanying drawing.
As Fig. 1, shown in Fig. 2, a kind of centrifugal blower comprises motor 1, draught fan impeller 2, assembling support 3 and intake grill 4, motor 1 is installed on assembling support 3, draught fan impeller 2 is arranged on the output shaft of motor 1, assembling frame 3 is also installed with U-shaped housing 5, described U-shaped housing 5 is by the top plate 5.1 be installed in assembling frame 3, lower plywood 5.2 and a U-shaped cover 5.3 assemble, described U-shaped cover 5.3 upper, lower surface is provided with the upper installing frame groove 5.5 and lower installing frame groove 5.6 that match with top plate 5.1 and lower plywood 5.2 respectively, circular open 5.7 is provided with in the middle part of described top plate 5.1, described intake grill 4 is fixedly installed on the circular open 5.7 of top plate 5.1.Described U-shaped housing 5 draught fan impeller 2 is placed in U-shaped housing 5 cavity.
For improving the pressure of U-shaped blower fan further, the sidewall of U-shaped housing 5 air-flow pressurization starting point is also provided with a guide plate 5.4.
As shown in Figure 4, draught fan impeller 3 axle center is respectively L1 to the lateral separation of the sidewall of U-shaped housing 5 air-flow pressurization starting point, fore-and-aft distance to U-shaped housing 5 cambered surface is L2, to being L3, L1≤L2≤L3 with the pressurize lateral separation of relative another sidewall of the sidewall of starting point of U-shaped housing 5 air-flow; For adapting to space limited in air-conditioner set, aperture α, β, wherein 45 °≤α≤90 ° respectively of U-shaped cover 5.3 both sides, 45 °≤β≤90 °.
The above embodiment only have expressed optimum mode of execution of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
