Description

Volute structure of air conditioner

Technical Field

The utility model belongs to the technical field of air conditioner and refrigeration engineering, specific theory relates to a spiral case structure of air conditioner.

Background

The structure of the volute of the air conditioner is always a problem which is continuously researched by air conditioner manufacturers and fan manufacturers, and when the existing volute is used for air outlet, air flow is easy to be blocked at two sides of the volute, and eddy current and noise are generated.

Disclosure of Invention

In order to solve the technical problem, the utility model provides an ignition switch with warning switch.

The utility model discloses a realize the technical scheme who takes of purpose does:

the utility model provides a spiral case structure of air conditioner, includes the spiral case body, this internal chamber that holds centrifugal wind wheel that is equipped with of spiral case, be equipped with on the spiral case body and hold the air outlet of chamber intercommunication, its characterized in that: air outlet department is equipped with noise-abatement structure, noise-abatement structure is including setting up first guide plate, the second guide plate in the air outlet both sides and setting up the spiral owner muscle on the air outlet, the inner wall of first guide plate and second guide plate is equipped with and falls the structure of making an uproar, fall the structure of making an uproar and include the mounting panel and set up the interlayer of making an uproar on the mounting panel of making an uproar, fall the interlayer of making an uproar and include that the first layer of making an uproar and the second falls the layer of making an uproar, the first layer of making an uproar and mounting panel fixed connection.

Furthermore, the spiral main ribs are multiple.

Furthermore, the cross section of the spiral main rib is triangular.

Furthermore, the first noise reduction layer is made of fiber materials, and the second noise reduction layer is made of sound insulation felt.

The utility model discloses a set up spiral owner muscle in air outlet department for guide air forms attaches the wall flow, has reduced the speed that the air flows, and the air resistance coefficient that slows down through the collision that reduces air and guide plate inner wall, has reduced the noise of air outlet, is equipped with the noise reduction structure through the inner wall at first guide plate and second guide plate, has further reduced the noise that air outlet department produced.

Drawings

Fig. 1 is a schematic view of the present invention.

Fig. 2 is a schematic view of the noise reduction structure of the present invention.

Detailed Description

The following describes in detail an embodiment of the present invention with reference to the drawings.

According to fig. 1-2, a spiral case structure of air conditioner, includes spiral case body 1, be equipped with the chamber 2 that holds centrifugal wind wheel in the spiral case body 1, be equipped with on the spiral case body and hold the air outlet 3 of chamber 2 intercommunication, air outlet 3 department is equipped with noise-abatement structure, noise-abatement structure is including setting up first guide plate 4, second guide plate 5 and the spiral main muscle 6 of setting on the air outlet in the air outlet both sides, spiral main muscle 6 is many, and even setting is in air outlet 3 department, and the cross section of spiral main muscle 6 is triangle-shaped, and the guide air that can be fine forms and attaches the wall flow like this, has reduced the speed that the air flows, and the air resistance coefficient slows down has reduced the noise of air outlet through reducing the collision of air and guide plate inner wall.

The inner wall of first guide plate 4 and second guide plate 5 is equipped with and falls the structure 7 of making an uproar, fall the structure of making an uproar and include mounting panel 8 and set up the interlayer of making an uproar on the mounting panel of making an uproar, fall the interlayer of making an uproar and include that the first layer of making an uproar 9 and the second falls the layer 10 of making an uproar, the first layer of making an uproar 9 and mounting panel 8 fixed connection of making an uproar, the second falls the layer 10 of making an upr. Noise reduction structures 7 are arranged on the inner walls of the first guide plate 4 and the second guide plate 5, so that noise generated at the air outlet is further reduced. The first noise reduction layer is made of fiber materials, and the second noise reduction layer is made of sound insulation felt.

Claims

1.
