Description
Technical field
This utility model relates to a kind of new blower fan of bidirectional flow, is specially the new blower fan of bidirectional flow of a kind of high-efficient noise-reducing.
Background technology
The new blower fan of bidirectional flow is to be placed in a casing by same to exhaust blower and pressure fan, during blower fan work, the new wind sent into and the air of discharge can carry out heat exchange by heat exchanger, the air of discharge and the new wind of feeding by the heat exchanger in fan box simultaneously, recover energy.Exhaust outlet is typically mounted at the region that the air pollutions such as kitchen, toilet, dining room are more serious, and air outlet is then arranged on the region that the air such as bedroom, living room, parlor are cleaner.Under the effect of blowing and discharging fan, outdoor fresh air is in the region inlet chamber such as bedroom, from the region discharge chambers such as toilet, if at indoor formation air circulation system, room air is replaced, keeps the cleaning of room air.The same area also can install exhaust outlet and air outlet simultaneously, and now, this region forms the new air circulating system of local, and this region is entered air displacement.But the new blower fan of existing bidirectional flow is in running, blower fan air-supply and air draft are through box house, and owing to the flowing of machine operation and air-flow can produce substantial amounts of noise, impact uses environment.
Utility model content
The purpose of this utility model is in that to provide the new blower fan of bidirectional flow of a kind of high-efficient noise-reducing, with the problem solving to propose in above-mentioned background technology.
nullFor achieving the above object，This utility model provides following technical scheme: the new blower fan of bidirectional flow of a kind of high-efficient noise-reducing，Including Blower Housing，The inner chamber of described Blower Housing is provided with dividing plate，The inner chamber of Blower Housing is separated to form air draft chamber and wind pushing cavity by described dividing plate，Described air draft chamber is positioned at the top of wind pushing cavity，The opposite sides inwall of described air draft chamber and wind pushing cavity is equipped with installing plate，Described installing plate is uniformly provided with silencing block，Groove is formed between silencing block described in adjacent two groups，The bottom of described groove is provided with bloop，Described bloop is positioned on installing plate，The inner chamber of described installing plate is provided with acoustical cotton layer，The both sides of described air draft chamber and wind pushing cavity are equipped with air vent，The top inwall of described air vent is uniformly provided with the first bloop，The bottom inwall of described air vent is uniformly provided with the second bloop，Described first bloop and the arrangement of the second bloop staggered relative.
Preferably, described silencing block is frustum hollow three-dimensional shape, and silencing block described in two adjacent groups is combined into corrugated.
Preferably, described silencing block, groove and bloop linear arrangement successively.
Preferably, described installing plate is hollow three-dimensional shape.
nullCompared with prior art，The beneficial effects of the utility model are: the new blower fan of bidirectional flow of this high-efficient noise-reducing，Noise reduction is good，The noise that air flowing produces can be effectively reduced，When air is by air vent，The noise the first bloop on air vent inwall that air-flow produces and the second bloop，Because staggered relative arrangement between the first bloop and the second bloop，Noise can be produced repeatedly refraction or diffraction，Thus having cut down the energy of noise，Decrease the probability entered within Blower Housing，Improve the isolation of its noise，Air draft chamber and the silencing block of wind pushing cavity inwall both sides is touched after noise enters Blower Housing inside，Because silencing block is frustum hollow three-dimensional shape，Multiple silencing blocks are combined into corrugated，Also noise can be produced repeatedly refraction or diffraction，When noise touches the groove formed between silencing block simultaneously，Can be entered by bloop to install in extremely and be absorbed by acoustical cotton layer，Noise circulates until disappearing in installing plate，Greatly reduce the noise pollution during work of new blower fan.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation；
Fig. 2 is this utility model A place schematic enlarged-scale view.
In figure: 1 Blower Housing, 2 dividing plates, 3 air draft chambeies, 4 wind pushing cavities, 5 silencing blocks, 6 installing plates, 61 bloops, 62 acoustical cotton layers, 7 air vents, 71 first bloops, 72 second bloops, 8 grooves.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.
nullRefer to Fig. 1-2，This utility model provides a kind of technical scheme: the new blower fan of bidirectional flow of a kind of high-efficient noise-reducing，Including Blower Housing 1，The inner chamber of Blower Housing 1 is provided with dividing plate 2，The inner chamber of Blower Housing 1 is separated to form air draft chamber 3 and wind pushing cavity 4 by dividing plate 2，Air draft chamber 3 is positioned at the top of wind pushing cavity 4，The opposite sides inwall of air draft chamber 3 and wind pushing cavity 4 is equipped with installing plate 6，Installing plate 6 is hollow three-dimensional shape，Installing plate 6 is uniformly provided with silencing block 5，Groove 8 is formed between adjacent two groups of silencing blocks 5，Silencing block 5 is frustum hollow three-dimensional shape，Two adjacent groups silencing block 5 is combined into corrugated，The bottom of groove 8 is provided with bloop 61，Bloop 61 is positioned on installing plate 6，Silencing block 5、Groove 8 and bloop 61 linear arrangement successively，The inner chamber of installing plate 6 is provided with acoustical cotton layer 62，The both sides of air draft chamber 3 and wind pushing cavity 4 are equipped with air vent 7，The top inwall of air vent 7 is uniformly provided with the first bloop 71，The bottom inwall of air vent 7 is uniformly provided with the second bloop 72，First bloop 71 and the arrangement of the second bloop 72 staggered relative.nullWhen air is by air vent 7，The noise that air-flow produces the first bloop 71 and the second bloop 72 on air vent 7 inwall，Because staggered relative arrangement between the first bloop 71 and the second bloop 72，Noise can be produced repeatedly refraction or diffraction，Thus having cut down the energy of noise，Decrease the probability entered within Blower Housing 1，Improve the isolation of its noise，Air draft chamber 3 and the silencing block 5 of wind pushing cavity 4 inwall both sides is touched after noise enters Blower Housing 1 inside，Because silencing block 5 is frustum hollow three-dimensional shape，Multiple silencing blocks 5 are combined into corrugated，Also noise can be produced repeatedly refraction or diffraction，When noise touches the groove 8 formed between silencing block 5 simultaneously，Can be entered in installing plate 6 by bloop 61 and be absorbed by acoustical cotton layer 62，Noise circulates until disappearing in installing plate 6，Greatly reduce the noise pollution during work of new blower fan.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art, being appreciated that when without departing from principle of the present utility model and spirit and these embodiments can be carried out multiple change, amendment, replacement and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
