The utility model reduces the whole size of the blower, and the arrangement is more compact; on the premise of the same external dimension, the power of the air blower is reduced, and the efficiency of the air blower is improved; on the premise of the same power, the air quantity is improved, and the noise of the air blower and the air conditioner is reduced.
Description
Technical Field
The utility model relates to the technical field of automobile air conditioners, in particular to a noise-reducing air blower with an arc-shaped hub.
Background
The air blower is an important part in automobile air conditioner parts, as shown in fig. 1, the shape of the existing air blower hub 2 is straight, the space that the hub can accommodate is very small, the relative distance between a motor and an impeller is large, in air conditioner integration, the gap between an air blower volute and a filter element is small, the air volume of an air conditioner assembly is small, and meanwhile, the noise of the air blower and the air conditioner integration is also large.
The person skilled in the art is dedicated to solving the above technical drawbacks.
SUMMERY OF THE UTILITY MODEL
In view of the above-mentioned drawbacks of the prior art, a technical object of the present invention is to solve the problems mentioned in the above-mentioned background art.
In order to achieve the technical purpose, the utility model provides a noise reduction blower with an arc-shaped hub, which comprises a blower impeller, a motor and an impeller volute, wherein the blower impeller consists of a blower blade main body and a blower hub, the blower blade main body is arranged at the periphery of the blower hub, the motor is arranged at the inner side of the blower hub, and the blower hub is arc-shaped.
Preferably, the distance between the impeller volute and the filter element is more than 30 mm.
The utility model has the beneficial effects that:
due to the structural design, the hub of the air blower is in an arc shape, so that the motor is closer to the impeller, the arrangement is more compact, and the overall size of the air blower is reduced; on the premise of the same external dimension, the power of the air blower is reduced, and the efficiency of the air blower is improved; on the premise of the same power, the air quantity is improved, and the noise of the air blower and the air conditioner is reduced.
Drawings
FIG. 1 is a schematic view of a prior art blower hub;
FIG. 2 is a schematic view of an air conditioner integrated structure according to the present invention;
FIG. 3 is a schematic structural view of a blower blade body and a blower hub according to the present invention;
fig. 4 is a schematic structural view of a blower hub according to the present invention.
In the figure: 1 blower blade main part, 2 blower wheel hub, 3 filter cores, 4 motors, 5 impeller volutes.
Detailed Description
The conception, the specific structure and the technical effects of the present invention will be further described with reference to the accompanying drawings to fully understand the objects, the features and the effects of the present invention.
Example (b):
as shown in fig. 2-4, the arc-shaped hub noise reduction blower comprises a blower impeller, a motor 4 and an impeller volute 5, wherein the blower impeller is composed of a blower blade main body 1 and a blower hub 2, the blower blade main body 1 is arranged at the periphery of the blower hub 2, the motor 4 is arranged at the inner side of the blower hub 2, and the blower hub 2 is arc-shaped.
Specifically, the blower hub 2 is arc-shaped, so that the accommodating space of the blower hub 2 is greatly increased, the arrangement between the motor 4 and the blower impeller is more compact, the arrangement space of the motor 4 is saved, and the relative distance between the impeller volute 5 and the filter element 3 is greatly increased, so that the air volume of the air conditioner assembly is increased, and the integrated noise of the blower and the air conditioner is greatly reduced;
the utility model optimizes the gap between the impeller volute 5 and the filter element 3, thereby improving the air quantity, reducing the noise of the motor 4 and the air conditioner during operation, synchronously reducing the current of the motor 4 by about 1.5-2A, greatly reducing the power of the motor 4 and improving the efficiency of the blower.
Specifically, when the relative distance between the impeller volute 5 and the filter element 3 is greater than 30mm, the noise integrated with the air conditioner of the air blower can be optimally removed, and in most air conditioners in the market at present, the relative distance between the volute and the filter element can only be 20-25 mm, so that the air volume is limited and the noise is caused.
The foregoing detailed description of the preferred embodiments of the utility model has been presented. It should be understood that numerous modifications and variations could be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts. Therefore, the technical solutions available to those skilled in the art through logic analysis, reasoning and limited experiments based on the prior art according to the concept of the present invention should be within the scope of protection defined by the claims.
