The silence fan with multiple holes is simple in design, adopts the centrifugal impeller which is silence relatively, and has fine sound absorbing and isolating effect due to flame-retardant sound absorbing materials arranged on the air inlet passage. In addition, the silence fan is smaller in volume, convenient in installation and low in noise.
Description
Technical field
The utility model relates to a kind of blower fan, is specifically related to a kind of quiet porous blower fan, is suitable for the usefulness of indoor air-changing.
Background technique
At present general family, office building, hotel are for solving the air quality in room, generally can adopt many top suction type ventilation fans to solve the air quality in each room, and as family general only can be in the toilet, parlor, kitchen can use the top suction type ventilation fan; The hotel only can use the top suction type ventilation fan in the toilet.Have time of 1/3rd to spend in sleep all one's life that someone was the statistics people, therefore the air quality in bedroom seems extremely important, particularly all can close the doors and windows under the situation of opening air-conditioning, indoor air just can not circulate, and muddy air influences people's health.And few people install ventilation fan in the bedroom now, its chief reason is a noise problem, the ventilation fan level of noise of a general minimum model is all about 30dB, that still is in the level of noise of the laboratory test of noise reduction, and want high a lot in actual use certainly, influence people's sleep quality, volume ratio is bigger comparatively speaking for another top suction type ventilation fan, and relatively difficulty is installed; Also have, general ventilation fan air quantity is too big, and power is too big, can lose too many energy.
The model utility content
The purpose of this utility model is at the problems referred to above deficiency, and the quiet porous blower fan that a kind of volume is less, easy for installation and noise is little is provided.
In order to achieve the above object, the utility model is by the following technical solutions:
A kind of quiet porous blower fan, comprise rack, motor and exhaust port, it is characterized in that: be provided with a receded disk impeller that is connected with motor in the described rack, be provided with the air intake passage that communicates with the receded disk impeller intake grill in the rack, the cabinet sidewalls of described air intake passage correspondence is provided with at least one intake grill, and described intake grill is connected by the air intake airduct with indoor air outlet.
Above-mentioned inlet air passage is provided with fire-retardant sound absorbing material.
Above-mentioned receded disk impeller is novel two-way air intake low noise receded disk impeller; Above-mentioned motor is a low noise ball bearing motor, is provided with temperature protective device in this motor.
Above-mentioned intake grill is 2-5.
Also comprise and be used to seal the connector cover that does not use intake grill.
The utility model is simple in structure, adopts quiet relatively receded disk impeller design, further is provided with fire-retardant sound absorbing material on the inlet air passage, and sound-absorbing and soundproof effect are good.The utility model is less, easy for installation and noise is little at volume.
Description of drawings
Fig. 1 is the utility model external structure stereogram;
Fig. 2 is the utility model structural representation;
Fig. 3 installs and uses schematic representation for the utility model.
Below by the drawings and specific embodiments the utility model is further described:
Embodiment
As shown in Figures 1 to 3, a kind of quiet porous blower fan described in the utility model, comprise a rack 1, motor 2 and exhaust port 4, the position of corresponding exhaust port 4 is provided with a receded disk impeller 3 that is connected with motor 2 in the described rack 1, be provided with the air intake passage 5 that communicates with receded disk impeller intake grill 31 in the rack 1, the cabinet sidewalls of described air intake passage 5 correspondences be provided with at least one intake grill 6 (according to actual usage requirement design one or two or three or more), described intake grill 6 is connected by air intake airduct 7 with indoor air outlet 8.
Above-mentioned rack is the rectangular metal cabinet.
In order further to reduce the noise of blower fan, above-mentioned inlet air passage is provided with fire-retardant sound absorbing material 9, and described receded disk impeller adopts novel two-way air intake low noise receded disk impeller, and motor 2 adopts low noise ball bearing motor.In order to improve the Security of use, be provided with temperature protective device in the above-mentioned motor 2.
Further concrete, above-mentioned intake grill 6 mostly is five most, can satisfy the use in five rooms simultaneously.The utility model also comprises and is used for sealing the connector cover (figure does not draw) that does not use intake grill, when intake grill 6 is idle obsolete, can adopt connector cover that it is sealed, and avoids causing fault, shortens motor working life.
Below come by specifically installing and using principle that the utility model is described in further detail:
Quiet porous blower fan of the present utility model can be installed in the ceiling board, or directly extension withstands under the roof, can be chosen in balcony, the Room, Rest Room, kitchen etc. installs the relatively low place of noise jamming requirement, and air outlet in the installation room is taken in the sky, room that needs the ventilation exhausting, air outlet is connected by the air intake airduct with indoor air outlet with the intake grill of quiet porous blower fan, as shown in Figure 3.Opening power during use, the rotation of driven by motor receded disk impeller, because the effect of negative pressure, the air outlet in each room sucks the air in the room, air enters quiet porous blower fan through the air intake guide duct, is discharged by exhaust port at last.
Few people install ventilation fan in the bedroom now, its chief reason is a noise problem, the ventilation fan level of noise of a general minimum model is all about 30dB, that still is in the level of noise of the laboratory test of noise reduction, and want high a lot in actual use certainly, influence people's sleep quality, volume ratio is bigger comparatively speaking for another top suction type ventilation fan, and relatively difficulty is installed.And the utility model is simple in structure, blower fan is not set directly in the room, bedroom, can be chosen in balcony, the Room, Rest Room, kitchen etc. installs the relatively low place of noise jamming requirement, and air outlet in the installation room is taken in the sky, room that needs the ventilation exhausting, and the intake grill and the indoor air outlet of air outlet and quiet porous blower fan join by the air intake guide duct.The room, bedroom does not almost have noise like this, guarantees people's normal rest.
The utlity model has following major advantage:
1. quiet
Rack of the present utility model is the square structure, and it is provided with fire-retardant sound-absorbing material at the inlet air passage, and the receded disk impeller after adopting simultaneously high-quality low noise ball bearing motor and passing through optimal design matches, with the level of making an uproar to best control. The return air inlet in body and each room adopts the air intake guide duct to join on the other hand, is not directly installed in the room, bedroom, and this point can effectively solve the noise problem that ventilation fan is used in the bedroom.
2. porous (a tractor serves several purposes)
The utility model arranges five return air inlets altogether, and the return air inlet in each room is connected with blower fan with the air intake guide duct, therefore can satisfy the air-conditioning requirement in five rooms simultaneously, and general one family uses a Fans just can satisfy the ventilating problem in room.
3. energy-conservation
An energy consumption 20W calculates with common ceiling type ventilation fan, and the total energy consumption of five machines is 100W, and the maximum energy consumption of 5 return air inlets of a present machine band is 70W, and energy-conservation 30%
4. safety
The utility model fan with multiple holes adopts built-in temperature protective device motor, all-metal cabinet structure and fire-retardant sound-absorbing material, improves the fire protecting performance of product.
