Abstract
The utility model relates to a host machine of a central suction cleaner. The silencers of existing suction cleaners are all arranged on the exhaust outlet of the suction cleaner, which has the shortages of being easy to generate air resistance, complex structure and inconvenient processing. Therefore, the host machine of the central suction cleaner comprises a shell, a fan and a motor which drives the fan; wherein, the fan and the motor are arranged in the shell; the air inlet of the fan is provided with a filter screen; a dust collecting barrel is arranged below the filter screen; the shell is internally provided with a round barrel-shaped internal shell which encircles the motor and is matched with a clapboard which isolates the cirque space between the internal shell and the shell to form an open ring exhaust passage; the head end of the open ring exhaust passage is communicated with the interior of the internal shell and the tail end thereof is connected with the exhaust outlet of the shell; silencing lining material is arranged on the internal circumferential wall of the shell, in the internal shell, on the external circumferential wall of the shell and below the middle cover of the fixed motor. The utility model has the advantages of small noise, simple structure and convenient processing. The utility model is an ideal dedusting equipment applied to high-class houses such as modern office buildings, hotels, villas, etc.
Description
Technical field
The utility model relates to a kind of central dust extractor main frame.
Background technology
When dust catcher brings clean environment for everybody, also brought certain noise pollution, the main frame of central dust extractor is fixed on a place (locating as balcony, garage etc.), is subjected to noise jamming smaller away from the room of this main frame, but is subjected to noise jamming still bigger near the room of main frame.Abate the noise and to start with from the source.
Existing noise absorption unit of dust collector all is arranged on the dust collector exhaust mouth, though certain erasure effect is arranged, is easy to generate vapour lock, and complex structure, processing inconvenience.
The utility model content
The technical problems to be solved in the utility model is how to overcome the existing big defective of central dust extractor noise, and a kind of central dust extractor main frame is provided.
For solving the problems of the technologies described above, the utility model central dust extractor main frame comprises the motor of housing, blower fan and driving blower fan, wherein, blower fan, motor are installed in the housing, fan air inlet is furnished with filter screen, the filter screen below is provided with dust bucket, it is characterized in that: be provided with drum shape inner casing in the described housing, this inner casing is around motor, and be furnished with dividing plate, this dividing plate cuts off the annular space between inner casing and the housing, forms the open loop type exhaust passage, this open loop type exhaust passage head end communicates with inner casing inside, the exhaust outlet on the tail end body contact body; The middle cover below of described housing inner peripheral wall, the inside and outside circumferential wall of inner casing and fixed motor is equipped with the noise reduction wadding.Can select the noise reduction cotton to make the noise reduction wadding.So design, motor, blower fan are surrounded by quieter material, and the mechanical noise that produces during the two work is decayed gradually in inside, and is absorbed by quieter material.The wadding of noise reduction simultaneously just smoothly is attached on the relevant surfaces, can not produce excessive obstruction to gas channel, and it is also comparatively convenient that processing is got up.
As optimization, be provided with the elastic damping pad between middle cover and the motor.Can select the pad of the EVA material system of certain elasticity and toughness for use.So design can prevent that noise and vibration from propagating to the external world by middle cover.
As optimization, be provided with the control of dust funnel in the described dust bucket, this control of dust funnel is Taper Pipe shape.So design, dust just can not leak outside after entering dust bucket by the control of dust funnel.
As optimization, described motor is dry type dust catcher motor, and its stator coil is exposed, the air-flow cooling that utilizes dust catcher to discharge.So design, simple in structure, volume is little, cost is low.
As optimization, described motor is for doing, wet dual-purpose type dust catcher motor, and its stator afterbody is provided with fan blade and fan housing, and the air entry top of fan housing is provided with the noise reduction spiral case, and the inner surface of the loam cake of this noise reduction spiral case inner surface and housing is provided with the noise reduction wadding.So design, motor sucks air by the noise reduction spiral case, is the motor cooling, and the gas that dust catcher sucks does not contact stator coil, can adapt to the instructions for use of wet environment, wide adaptability, and also noise is little.
The utility model central dust extractor main frame has noise advantage little, simple in structure, easy to process, is the desirable cleaner of senior dwelling houses such as modern handle official bussiness building, hotel and villa.
