The low noise air conditioner fan comprises a volute including an air inlet and an air outlet, an impeller arranged in the volute, and a motor for driving the impeller to rotate, and also comprises a box body arranged outside the volute, the air outlet is communicated with the outer side of the box body, and a sound insulation piece is filled between the box body and the volute. The low noise air conditioner fan has the advantages that the structure is simple, the noise is low and the like.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of low noise air-conditioning draught fan.
Background technique
Because air-conditioning draught fan is contained in occasions such as hotel, office area, civilian ventilation mostly, to the requirement of noise than higher.Existing air-conditioning draught fan comprises spiral case, be located at the impeller in the spiral case and drive the motor of this wheel rotation, and air-conditioning draught fan because the rotation of impeller can produce noise, affects to environment in the process of work.
For this reason, people explore through long-term, have proposed various solutions, and some has also applied for patent.For example, Chinese patent discloses a kind of squelch type air-conditioning draught fan [notice of authorization number be: CN 201843837U], comprises the blower fan body; The bottom of this blower fan body is provided with centrifugation blade, is provided with the spiral case air channel on centrifugation blade top, in the spiral case air channel, is provided with the snail tongue body; Snail tongue body end is provided with the snail lingual surface of turnover, and the snail lingual surface is provided with quiet parts, goes up strip noise reduction rib through snail tongue table; The transition that each pressure section is asked when making air-flow through the snail tongue is comparatively mild; Reduce the generation of acoustic energy, on the basis that does not influence fan performance and energy consumption, effectively suppress snail tongue noise, further reduce the aerodynamic noise of cabinet type air conditioner indoor set.But the manufacture cost of this air-conditioning draught fan is high, is difficult for being accepted by users.
Summary of the invention
The purpose of the utility model is to have the problems referred to above to existing technology, has proposed that a kind of soundproof effect is good, a kind of low noise air-conditioning draught fan of low cost of manufacture.
The purpose of the utility model can realize through following technical proposal:
This low noise air-conditioning draught fan; Comprise spiral case, be located at impeller in the spiral case and the motor that drives this wheel rotation with intake grill and exhaust outlet; It is characterized in that; This air-conditioning draught fan also comprises the casing that is sheathed on the spiral case outside, and the above-mentioned exhaust outlet and the external communications of said casing are filled with sound insulating member between described casing and spiral case.
The outside through at air-conditioning draught fan increases the sound insulation casing, between casing and spiral case, is filled with sound insulating member, effectively reduces the noise of blower fan, and the comparable original blower fan of noise reduces about 5～8dB; Beautiful shape is generous, has effectively improved the appearance quality of product, and simple in structure, cost is low.
In above-mentioned low noise air-conditioning draught fan; Described casing is square; Sidewall at said casing offers a through hole; Above-mentioned exhaust outlet is positioned at described through hole, and is provided with the flexible pipe that an end is communicated with exhaust outlet in described through hole, and the other end of said flexible pipe passes through hole and extends to the outside of casing.
In above-mentioned low noise air-conditioning draught fan, described casing is processed by soundproof material.
In above-mentioned low noise air-conditioning draught fan, described sound insulating member is a Sound-proof material.
Compared with prior art, this low noise air-conditioning draught fan has the following advantages:
The outside through at air-conditioning draught fan increases the sound insulation casing, between casing and spiral case, is filled with Sound-proof material, effectively reduces the noise of blower fan, and the comparable original blower fan of noise reduces about 5～8dB; Casing is square, and makes the beautiful shape of blower fan generous, has effectively improved the appearance quality of product, and simple in structure, cost is low.
Description of drawings
Fig. 1 is the structural representation of this low noise air-conditioning draught fan.
Among the figure, 1, spiral case; 11, exhaust outlet; 2, casing; 3, sound insulating member; 4, flexible pipe.
Embodiment
Below be the specific embodiment of the utility model and combine accompanying drawing, the technological scheme of the utility model is done further to describe, but the utility model is not limited to these embodiments.
As shown in Figure 1, this low noise air-conditioning draught fan comprises spiral case 1 with intake grill and exhaust outlet 11, is located at impeller in the spiral case 1 and the motor that drives this wheel rotation.
As shown in Figure 1, be provided with a casing 2 in the outer cover of spiral case 1, the exhaust outlet 11 of spiral case 1 and the external communications of casing 2 are filled with sound insulating member 3 between casing 2 and spiral case 1.
As shown in Figure 1, this casing 2 is square and is processed by soundproof material.Sidewall at casing 2 offers a through hole, and exhaust outlet 11 is positioned at the through hole, and is provided with the flexible pipe 4 that an end is communicated with exhaust outlet 11 in the through hole, and the other end of flexible pipe 4 passes through hole and extends to the outside of casing 2.
In the present embodiment, sound insulating member 3 is a Sound-proof material.
The outside through at air-conditioning draught fan increases sound insulation casing 2, between casing 2 and spiral case 1, is filled with Sound-proof material, effectively reduces the noise of blower fan, and the comparable original blower fan of noise reduces about 5～8dB; Casing 2 is square, and makes the beautiful shape of blower fan generous, has effectively improved the appearance quality of product, and simple in structure, cost is low.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from the spirit of the utility model or surmount the defined scope of appended claims.
Although this paper has used terms such as spiral case 1, exhaust outlet 11, casing 2, sound insulating member 3, flexible pipe 4 morely, do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain the essence of the utility model more easily; It all is contrary with the utility model spirit being construed to any additional restriction to them.
