CN2259129Y - Silencing device for suction cleaner - Google Patents

Abstract

The utility model discloses a silencing device for a suction cleaner, which mainly comprises an upper cover, an air dispersing sheet, a silencing plate, a motor casing, a motor, an upper flow guide plate, a lower flow guide plate, and a chassis. Through making use of an air choking sheet, the air outlets of the upper and the lower flow guide plates are separated; when the air flows across spoiler sheets which are alternatively arranged, noise is reduced; after the air which flows across the spoiler sheets is exhausted from the exhaust holes of the upper cover, and then, the air dispersing sheet makes the exhausted air dispersed. Accordingly, the noise is reduced again; in addition, the silencing plate on the motor casing can eliminate the noise generated by the motor and a portion of the noise of the air stream which is exhausted from wall holes, and accordingly, silencing effects can be obtained.

Description

The silencing means of dust catcher

The utility model relates to a kind of silencing means of dust catcher, refers to the general relatively large silencing means of doing, wetting two-purpose dust collector especially.

Living standard raising along with current society, people improve with attention day by day to the cleaning of home environment, it is also increasing to clean used tool kind, dust catcher then is go-go a kind of in the burnisher, by its can dust suction, absorb water, dry up, thereby reach the effect of cleaning ambient.Though dust catcher on the market has above-mentioned function mostly now, noise is excessive during operation, and the most outstanding with the general relatively large dual-purpose dust catcher of doing, wet especially.Cause will be strengthened its suction, thus all install more powerful motor, and structurally do not have any silencing means (as shown in Figure 7), therefore the noise that is produced when operation is very big, like this noise of high-decibel, the comfort when not only influencing the user and operating, and influence household's health.

The purpose of this utility model is to provide a kind of silencing means of dust catcher, so that reduce the noise that is produced when dust catcher is operated.

For achieving the above object, the silencing means of the utility model dust catcher comprises loam cake, loose wind sheet, acoustical panel, motor case, baffle upper plate, chin spoiler and chassis.Wherein: loam cake is a semicircle ducted body, and the one side is established an exhaust duct, and in pipe, establish one with loam cake in the vent that communicates.The wind sheet that looses is the curved sake body in a two sides, and this diffusing wind sheet area can be greater than the area of outlet.Acoustical panel is the semi-circular plate of an arc, and a motor case hole of offering according to the motor shape of hood is arranged in the middle of it; Around its hole, be provided with in addition three with the motor case on the corresponding through hole of three projections.The motor case is a cap-shaped body, is a case in the middle of it, and the bottom is a cover plate, has one can hold the space of Na Mada in the case, and establishes several cinclides on the perimeter wall of case lower end; The external wind channel of case is offered a wind channel exhaust vent in its outside, and establishes a cover plate exhaust vent with cover plate place that wind channel joins; On the cover board establish three and the corresponding five equilibrium projection of chassis three projections in addition.Motor is the motor that general dust catcher uses.Baffle upper plate is a circular slab, establishes a peripheral flanged motor containing hole in the middle of it, and offer a baffle upper plate exhaust vent with wind channel exhaust vent opposite position place on baffle upper plate; Around the motor containing hole, establish in addition three with the chassis on the corresponding five equilibrium through hole of three projections; Establish the spoiler of several five equilibriums at the baffle upper plate back side.Chin spoiler is a circular slab, also offers a peripheral flanged motor containing hole in the middle of it, and the flange on this flange and the baffle upper plate can chimericly be one, and the motor containing hole establish all around three with the corresponding five equilibrium through hole of three projections on the chassis; On chin spoiler plate face, establish the spoiler and a wind-retarding plate of several five equilibriums in addition, spoiler on this spoiler and the baffle upper plate forms and is staggered, and intermediate width was smaller when it was highly all chimeric than two deflectors, and the height of wind-retarding plate just is the chimeric back of two a deflectors intermediate width; Offer the chin spoiler exhaust vent on the wind-retarding plate next door in addition, when two deflectors were chimeric, the exhaust vent on two plates was just separated by wind-retarding plate.The chassis is a circular bearing, establishes a wind inlet and a motor seat on its base plate, is provided with the projection of three five equilibriums around the motor seat; Two layers of recessed edge are arranged on the chassis.

During combination, motor is placed on the motor seat on chassis, the motor containing hole of chin spoiler and through hole pass the projection on motor and chassis respectively, and chin spoiler places on the recessed edge of the chassis second layer; Motor containing hole and through hole with baffle upper plate passes projection on motor and the chassis again, its flange and chin spoiler flange tabling, and place on the recessed edge of chassis ground floor; This moment, on motor, cover plate was placed on the recessed edge of chassis ground floor, and makes cover plate exhaust vent and baffle upper plate exhaust vent be aligned to a passage with the motor cover clamshell, and three projections on the cover plate align with three projections on chassis, so that utilize screw to lock; The motor case hole of acoustical panel and through hole are passed projection on case and the cover plate respectively, and acoustical panel is positioned on the motor case and just in the upper end of cinclides; Loam cake is covered on the motor case again and is entrenched on the chassis, its vent aligns with the wind channel exhaust vent, forms a passage; The wind sheet spiral shell that will loose at last is solid on the connector of exhaust duct.

After adopting said structure, utilize wind-retarding plate that the air outlet of upper and lower deflector is separated, make air flow through staggered spoiler and reduce noise; The air of being discharged by the loam cake steam vent stops and scatters through the wind sheet that looses again, thus low noise once more; Eliminate noise and a part of noise that flows from the air of cinclides discharge that motor itself is produced by acoustical panel on the motor case in addition, make the utility model reach the effect of noise reduction thus.

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
