Abstract

The noise reduction mechanism uses a motor cover fitted around the outside of the vacuum cleaner motor, enclosed by a front motor housing, defining a meandering path for the air fed to a central air outlet in the base of the motor cover. The central opening may communicate with a curved air outlet channel, the acylic component defining the air exit path covered with a felt material.

Description

The noise reducing mechanism of vacuum cleaner motor

The present invention in a word relates to a kind of noise reducing mechanism of vacuum cleaner motor.Specifically, the noise reducing mechanism of the vacuum cleaner motor that relates in vacuum cleaner operating period, can reduce the noise of hearing from the outside largely.

General vacuum cleaner motor can produce noise when operation, there are many research and development persons once attentively to endeavour the noise reducing mechanism of vacuum cleaner, the noiseless performance of this noise reducing mechanism against vacuum dust catcher, and prevent that it is very important that the people that work or have a rest are interfered on every side.

Shown in Fig. 1 is general noise reduction system.Forwards making progress of motor 10, packing ring 20 before in turn disposing, the procapsid 30 of motor and motor seal 40, the back of motor 10 is then connecting motor filter 50, the back casing 70 of packing ring 60 and motor.The procapsid 30 and the back casing 70 of motor are connected to each other by bolt 80, are fitted in then in the motor outer cover 90, use nut 100 fastening again.Motor outer cover 90 utilizes bolt 120 to be fastened in the inner space 111 of main body of dust collector 110.The noise delivery outlet 11 that noise forms from motor 10 back sides, the motor filter 50 of flowing through, enter first quadrangle delivery outlet 71 that is formed on motor field frame 70 inner peripherys, and then, flow out the flow export of main body of dust collector 110 by being formed on two the second quadrangle delivery outlets 91 on motor outer cover 90 inboard both sides.The race ring that label 92 expression motor seals 40 are fitted in wherein.

Reduce distance according to general noise, during motor 10 operations, the noise of externally hearing by noise delivery outlet 11 is the first quadrangle delivery outlet 71 on motor filter 50 and motor rear case 70, passes the second quadrangle delivery outlet 91 to motor outer cover 90.Noise is the delivery outlet that outputs to main body of dust collector 110 through an additional passage, thereby noise has reduced a bit.But, general noise reduction system can not fully be eliminated the noise that is produced by vacuum cleaner motor.

An object of the present invention is to provide a kind of noise reducing mechanism of vacuum cleaner motor, this mechanism utilizes the shape that changes the motor outer cover, can make the noise of transmission quadrangle delivery outlet on motor rear case, before the outlet of discharging main body of dust collector, reduce widely, thereby provide a kind of more good noise to reduce effect.

In order to achieve the above object, the invention provides a kind of noise reducing mechanism of vacuum cleaner motor, wherein, noise from the noise delivery outlet at motor back, flow through and be contained in motor filter in the motor rear case, the quadrangle delivery outlet that forms on the inner periphery on the back casing in the output warp connects together, motor is contained in the motor procapsid again, and make on the passage that it is fastened on the motor outer cover on the main body of dust collector with bolt under the noise reduction, discharge the outlet of main body of dust collector again.

Extremely shown in Figure 4 as Fig. 2, noise from motor 10 back side noise delivery outlets 11, through being arranged in the motor filter 50 of motor rear case, introduce quadrangle delivery outlet 71 then, connecting together with motor procapsid 30, forming quadrangle delivery outlet 71 on the inner periphery on the back casing 70 in motor 10 is contained in.Make it in the motor outer cover 130 of noise in the space 111 that is fitted in main body of dust collector 110 with bolt 120 to reduce, flow out the flow export 112 of main body of dust collector 110 then, as shown in Figure 3, there is a tetragonal perforate 132 in inner bottom part 131 central authorities of motor outer cover 130, be used for the noise that weakens is discharged the outside, below quadrangle perforate 132, be formed with a circular arc, with the output pipeline section 133 that perforate 132 is connected, make noise pass to motor procapsid 30 through quadrangle perforate 132.

Label

140 and 150 is represented an acrylic panel and an adhesive-bonded fabric separately, is used to form a passage.

Reduce approach according to noise of the present invention, from the noise of motor bottom noise delivery outlet 11 outputs, approach motor filter 50, the quadrangle delivery outlet 71 of the motor rear case of flowing through again 70.Flow out output pipeline section 133 and passage through quadrangle perforate 132 again then, drain into the outlet 112 of main body of dust collector 110 by constituting by acrylic panel 140 and non-woven fabric 150.

The discharging road of noise becomes very long, thereby noise reduces a lot.

Fig. 5 and Fig. 6 illustrate second preferred embodiment of the present invention.In this embodiment, motor outer cover 130 has two circular holes 134 that closely contact with motor procapsid 30 on its sidewall.These two circular holes 134 given distance that separates each other.

Reduce approach according to the noise of second preferred embodiment, from the noise of the noise delivery outlet 11 of motor 10, approach motor filter 50 reaches the quadrangle delivery outlet 71 of motor rear case 70.Again by the circular hole 134 and the passage of motor outer cover 130, drain into the outlet 112 of main body of dust collector 110 then by constituting by acrylic panel 140 and non-woven fabric 150.

Noise from the quadrangle delivery outlet 71 of motor rear case 70 is exported reaches the circular hole 134 with the motor outer cover 130 of procapsid 30 contacts, because the discharging approach of noise is elongated, thereby causes the reduction of noise.

Fig. 7 and Fig. 8 schematically illustrate the noise reducing mechanism of the vacuum cleaner motor of the 3rd preferred embodiment of the present invention.The motor outer cover 130 of the 3rd preferred embodiment contacts with motor procapsid 30 at it, has a semicircle outlet 135 with motor seal and the downside that is connected again.

Noise according to the 3rd preferred embodiment reduces approach, noise from the noise delivery outlet 11 of motor 10, approach motor filter 50 reaches the quadrangle delivery outlet 71 of motor rear case 70, then the semicircle outlet 135 by motor outer cover 130 again.Subsequently, noise is disposed to the outlet 112 of main body of dust collector 110 again through the passage that is made of acrylic panel 140 and non-woven fabric 150.

From the noise that the quadrangle delivery outlet 71 of motor rear case 70 is exported, the semicircle outlet 135 of defeated motor outer cover 130 through contacting with motor procapsid 30, therefore, the passage of formation is that the passage of second preferred embodiment together is similar.

Fig. 9 and Figure 10 show the 4th preferred embodiment of the present invention.Motor outer cover 130 has two flange 136 along its circumference, a groove 72 made from the rear side 73 and the front side of motor rear case 70 contacts, these two flange 136 make motor outer cover 130 form a space 137 with the excircle of motor rear case 70, and form an outlet 138 by a predetermined portions that cuts flange 136 and space 137.

In the noise reducing mechanism in the 4th preferred embodiment, noise from noise delivery outlet 11 output of motor 10, by way of motor filter 50, flow through the quadrangle delivery outlet 71 of motor rear case 70, turn to 180 degree then,, flow out outlet 138 along the space 137 of motor outer cover 130, the passage of flowing through and being made of acrylic panel 140 and non-woven fabric 150 is sent the outlet 112 of main body of dust collector 110.

As mentioned above, the discharging approach of the noise that produces when being moved by motor can have multiple variation approach by the shape that changes motor outer cover 130, and it is elongated to make it passage, thereby the noise of hearing from the outside during vacuum cleaner operation just can reduce widely.
