Abstract

The utility model discloses air dust for a dust collector and a dust collector, comprising a body, which is enclosed by a casing. A dust cup is arranged at the front part of the body, and a motor chamber for placing a motor is positioned at the back part of the body. The utility model is characterized in that the tail of the motor directs towards a dust cup. The utility model prolongs the length of the air duct through simply readjusting the arrangement mode of the motor in the dust collector, the positions of the air inlet and outlet of the motor chamber and the layout angles of the air exit on the body and the dust cup, so that the deflection effect of the air duct is increased and the noise is reduced without lengthening the body.

Description

Dust catcher

Technical field

The utility model relates to a kind of dust catcher, is specifically related to the dust catcher that a kind of air channel layout is improved.

Background technology

Present dust catcher, especially bedroom dust catcher, the front fuselage that air surrounds from the housing pipe of giving a dinner of welcome enters in the housing chamber air inlet duct that is communicated with dirt cup air inlet, through entering the motor room that is furnished with motor again behind the multistage filtering device in the dirt cup, from the housing exhaust outlet at rear portion, motor room, discharge at last; In the above-mentioned air channel layout of existing dust catcher, the head of motor is all towards the dirt cup, because the air inlet of motor room all should be arranged in this side of motor head, so the air outlet on the dirt cup often just directly faces toward the air inlet of motor room; And the grid type exhaust outlet of housing rear end directly faces toward motor room's air outlet, and the path is all not only short but also lack complications, makes that the air channel overall noise is bigger.Certainly also have and the air channel of this class dust catcher is carried out improved, method generally all is to expand volume by increasing fuselage length, prolongs the air channel, or inserts tortuous airduct etc., and effect is all not obvious.

Summary of the invention

The utility model purpose is: a kind of dust catcher is provided, and its inner air channel layout can reduce noise effectively, and does not increase vacuum cleaner body length.

The technical solution of the utility model is: a kind of dust catcher, comprise the fuselage that housing surrounds, and fore-body is installed the dirt cup, and the rear portion is provided with the motor room of laying motor, and the afterbody that it is characterized in that motor is towards the dirt cup.

The detailed features of the above-mentioned main technical schemes of the utility model is to have a dirt cup air outlet on the dust cup of dust collector, the motor room has motor room's air inlet, one upper air duct is arranged in the described fuselage, and this upper air duct one end links to each other with the air inlet of motor room, and the other end links to each other with dirt cup air outlet.Since in the utility model motor be afterbody towards the dirt cup, motor room's air inlet can't directly face toward dirt cup air outlet on arranging, so make upper air duct obtain prolongation under the situation that does not increase fuselage length.Concrete extending length is decided according to different vacuum cleaner body length, and the length of upper air duct at least should be greater than motor length certainly.

The utility model is in order further to increase the tortuosity in air channel, its further technical scheme is that fore-body has a depressed part that is used to install the dirt cup, and the dirt cup is in tilted layout in this depressed part, and its top exposes outside fuselage, and the bottom of depressed part has a filter.Fuselage also is included in the fuselage exhaust outlet of its sidepiece, be connected with filter and above filter, the upper air duct below has a lower air duct, this lower air duct one end links to each other with motor room's air outlet, the other end links to each other with filter, and the interior airflow direction of airflow direction and upper air duct in this lower air duct is opposite.Be provided with extra large handkerchief screen pack in the above-mentioned filter, its effect is the same with prior art, mainly is the air that motor room's air outlet is discharged is further filtered.

Because motor is that afterbody is towards the dirt cup, make the upper air duct between dirt cup air outlet and motor air inlet have at least one bending, so the gas that comes out from the dirt cup must turn round and just can enter the motor room, has obviously prolonged dust catcher air channel length, has increased dust catcher air channel tortuosity; Simultaneously because fore-body further is provided with a depression that the dirt cup is tilted, concave bottom just can be reserved a wedge chamber and be used to arrange filter, make the gas that comes out from motor room's air outlet behind lower air duct, also must could discharge from the fuselage exhaust outlet through this filter, and this fuselage exhaust outlet is out at the fuselage sidepiece, obviously further prolong air channel length, increased the air channel tortuosity, effectively weakened with damping noise.

The utility model advantage is:

By in dust catcher inside to the arrangement of motor, motor room into and out of the position, air port, the layout angle of fuselage exhaust outlet and dirt cup simply readjusts to reach and prolongs air channel length, increase the effect of air channel tortuosity, both reach reduction noise purpose thus, and do not increased fuselage length.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further described:

Fig. 1 is a structure division cross-sectional schematic of the present utility model.

Fig. 2 is a structure division vertical view of the present utility model.(removing the dirt cup)

Wherein: 1, fuselage; 11, fuselage exhaust outlet 2, dirt cup; 21, dirt cup air outlet; 3, motor room; 31, motor room's air inlet 32, motor room's air outlet 4, air inlet duct; 5, filter, 6 motors 7, upper air duct; 8, lower air duct.

The specific embodiment

Embodiment: Fig. 1, Figure 2 shows that a kind of specific embodiment of the utility model dust catcher, it comprises the fuselage 1 that housing surrounds, the fuselage 1 anterior dirt cup 2 of installing, and the rear portion is provided with the motor room 3 that motor 6 is installed, and the afterbody of motor 6 is arranged towards dirt cup 2.

There is a depressed part that is used to install dirt cup 2 fuselage 1 front portion, and dirt cup 2 is in tilted layout in this depressed part, and the top of dirt cup 2 exposes outside fuselage 1, and a wedge chamber is formed on the bottom of depressed part, arranges a filter 5 in the wedge chamber.Fuselage 1 front portion has the air inlet duct 4 that is communicated with dirt cup air inlet, and owing to being in tilted layout of dirt cup 2, air inlet duct 4 must have a bending that makes progress could be communicated with dirt cup air inlet, and certainly owing to the view reason, dirt cup air inlet does not mark.

Be upper air duct 7 between dirt cup air outlet 21 and the motor room's air inlet 31, the length of this upper air duct 7 is greater than motor 6 length.Upper air duct 7 belows are a lower air duct 8, and these lower air duct 8 one ends link to each other with motor room's air outlet 32, and the other end links to each other with filter 5.

Fuselage exhaust outlet 11 is opened in the fuselage sidepiece, is connected with filter 5 and above filter 5.

Arrow among Fig. 1, Fig. 2 is the air flow direction in the present embodiment, after air enters fuselage 1, enter the dirt cup through air inlet duct 4, device filters the back and comes out could enter motor room 3 from motor room's air inlet 31 from dirt cup air outlet 21 after upper air duct 7 turns round after filtration, the gas that comes out from motor room's air outlet 32 enter lower air duct 8 through after the further filtrations of filter 5 just the fuselage exhaust outlet 11 from the housing sidepiece flow out dust catchers.Because the prolongation in the whole air channel of dust catcher and the increase of tortuosity have effectively weakened with damping noise.

Because the utility model is by the arrangement to motor 6 in dust catcher inside, motor room 3 into and out of the position, air port, the layout angle of fuselage exhaust outlet 11 and dirt cup 2 simply readjusts to reach and prolongs the whole air channel of dust catcher length, increase the effect of air channel tortuosity, both reach reduction noise purpose thus, do not increased fuselage length again.
