Abstract
The invention discloses a layered runner motor shell of a dust collector and belongs to electric mechanical equipment of the dust collector. The layered runner motor shell of the dust collector comprises inner shell bodies, square outer shells, outer shell air inlets and exhaust ports, wherein dust collection motors are respectively arranged in the inner shell bodies; the inner shell bodies are provided with vent holes; the square outer shells are arranged outside the inner shell bodies at certain spatial distance; each outer shell consists of an outer shell body and an outer shell cover; the outer shell air inlets are formed on the top of the corresponding outer shell covers; the exhaust ports are used for exhausting air from the outer shells; transverse clapboards for partly dividing the inside spaces of the outer shell are formed in the outer shells; the vent holes are formed on the peripheral walls of the inner shell bodies at the side that the center lines of the circle centers are passed through below the transverse clapboard so as to form lower clapboard channels and upper clapboard channels; and uplink runners and downlink runners are formed at the parts which are not divided by the transverse clapboards. By the layered runner motor shell adopting the design, the lengths of the runners for exhausting air are increased and the transmission loss of noise is improved, so that the noises generated when the motor shell of the dust collection exhausts the air are reduced.
Description
Technical field
The present invention relates to the electricapparatus equipment of dust catcher, specifically is a kind of layering runner motor casing of dust catcher.
Background technology
Dust catcher is a kind of cleaning and sanitary electric equipment device, is used for removing the dust in ground, carpet, wall, furniture, clothing and various slits.
Profile classification according to dust catcher can be divided into vertical type dust collector, horizontal (pot type) dust catcher and portable dust collector etc.
The dust catcher general structure comprises by the motor of dust collector that imports electric current generation suction, forms suction nozzle, the dust pick up hose of air path system, filter, and the dust collect plant of assembling inhalation (inhalatio).
Motor of dust collector at the generation negative-pressure sucking of inner of dust catcher body setting is placed in the motor box, and generates air and discharge air-flow.
Chinese patent 101084819 discloses a kind of " vacuum cleaner ", electric machine assembly wherein, and it is used for sucking air to above-mentioned body of dust collector, and its pressure is flowed; Motor housing, it includes cavity inner wall and chamber outer wall, and wherein above-mentioned cavity inner wall is configured for holding the motor cavity of above-mentioned electric machine assembly, and above-mentioned chamber outer wall forms along the outer periphery of the above-mentioned cavity inner wall set a distance of both being separated by; Wherein upper panel is also installed on the top of the cavity inner wall of motor housing and chamber outer wall, thereby the bottom surface that forms by above-mentioned upper panel and cavity inner wall, chamber outer wall and motor housing surrounds the space that forms.But it produces the present invention in effective attenuation electric machine assembly and to the motor housing of the noise of external communication, to reduce the noise of vacuum cleaner by adopting.
Fig. 1 is the vertical profile structural representation of prior art motor casing, as shown in Figure 1, in the inside of dust catcher body (not shown), dust sucting motor 1 is installed in the inner housing 2a, the top of inner housing 2a is provided with the interior cap 4 that forms inner casing air inlet 3a, and densely covered air vent hole 5 is formed at the bottom.The outside of inner housing 2a also is provided with the shell 13a that keeps the certain space distance with it, shell 13a is made of shell body 6a and casing cover 7a, casing cover 7a center of top on shell body 6a is formed with shell air inlet 8a, the inner casing air inlet 3a place of cap 4a is provided with absorbing silencer 9 on the corresponding inner housing, enters the noise of gas in order to reduction; Be provided with the beam 10 that reduces motor oscillating between the inner bottom part of shell body 6a and inner housing 2a, the sidewall of shell body 6a is formed with the outer up exhaust passage of shell, and through exhaust outlet 11a clean air is discharged to outside the dust catcher body.
Gas communication process in the motor casing of the above-mentioned prior art of brief description.Through the negative pressure pure air behind the inner dedusting of dust catcher body (not shown), filtration, the control of dust, muffler 9 noise reductions after the shell air inlet 8a on the casing cover 6a enter in the shell body 6a, and enter dust sucting motor 1 by the inner casing air inlet 3a of cap 4a in the inner housing, and the gas of discharging via dust sucting motor 1 gas outlet, the air vent hole 5 that gathers by inner housing 2a bottom enters in the shell body 6a, and outer up runner 12a and the exhaust outlet 11a of shell 13a that forms by shell body 6a one side, the air of cleaning is discharged to outside the dust catcher body.
But, above-mentioned prior art have a following deficiency, nearer via the gas that discharge dust sucting motor 1 gas outlet apart from the exhaust outlet 11a of shell body 6a, too short at the air flow channel in shell body 6a, therefore, limited to slackening of noise, noise reduction is not obvious, and use foamed plastics (not shown) to absorb noise merely, can not fully solve the problem that noise reduces.
Summary of the invention
The present invention is exactly in order to solve in the prior art, in the ubiquitous motor casing gas flow too short, utilize the foamed plastics sound-absorbing merely, the unconspicuous problem of noise reduction, and a kind of layering dual channel motor casing of dust catcher is provided.
The present invention realizes by following technical scheme.
A kind of layering runner motor casing of dust catcher, comprise built-in dust sucting motor and be formed with the inner housing of air vent hole, be arranged on the square shell of the outside also interval of inner housing certain space distance, shell is made of shell body and casing cover, be formed on the shell air inlet at casing cover top, and discharge the exhaust outlet of gas from shell, and and being formed with the diaphragm plate that the inner space part is separated in the enclosure, air vent hole is formed on inner housing and crosses on the following perisporium of the diaphragm plate of center of circle center line one side.
She Ji the present invention is owing to be formed with the diaphragm plate that the inner space part is separated in the enclosure like this, thereby formed dividing plate lower floor passage and dividing plate upper strata passage, and the part that is separated by diaphragm plate does not form up runner and descending runner.In addition, air vent hole is formed on inner housing and crosses on the following perisporium of the diaphragm plate of center of circle center line one side, the gas of discharging from inner housing must be detoured after, discharge from the exhaust outlet of shell body again.Therefore, increase the flow channel length that air-flow is discharged, increased the propagation loss of noise, and then reduce the noise that the motor of dust collector shell is discharged gas.
