To shown in Figure 6, vacuum cleaner 100 has main body of dust collector 10 as Fig. 1, to the main body of dust collector 10 inner air that suck, makes the mobile fan electromotor assembly 30 of air, accommodates the motor cavity 40 of fan electromotor assembly 30.Motor cavity 40 has the 1st motor cavity 41 that is installed in main body of dust collector 10 inside, is used to accommodate fan electromotor assembly 30, be arranged on the 1st motor cavity 41 around, form the 2nd motor cavity 43 of exhaust channel 49 with the lateral surface of the 1st motor cavity 41.
In the place ahead of main body of dust collector 10, be formed with the main body suction inlet 11 that passes air into main body of dust collector 10 inside that is communicated with suction nozzle.
Be provided with the cleaner handle 13 that to carry main body of dust collector 10 on the top of main body of dust collector 10.In addition, in the both sides, rear of main body of dust collector 10 wheel 15 that main body of dust collector 10 is moved is installed; Be provided with the rotatable caster (figure slightly) that to change direction of advance in the place ahead of main body of dust collector 10.
Dust collect plant 20 is releasably installed at rear at main body of dust collector 10.Dust collect plant 20 segregating foreign objects and it is carried out control of dust from the suction nozzle inhaled air.Dust collect plant 20 is arranged on the dust collecting container cover 23 on dust collecting container 21 tops by cylindric dust collecting container 21, and handle 25 formations that are used to carry dust collect plant 20.
In main body of dust collector 10 inside, the distribution portion (figure is slightly) of control vacuum cleaner 100 is installed, and the fan electromotor assembly 30 that sucks air by force, makes it to flow to main body of dust collector 10 inside.
As shown in Figure 3, motor cavity 40 comprises the 1st motor cavity 41 that is used to accommodate fan electromotor assembly 30, be arranged on the 1st motor cavity 41 around, form the 2nd motor cavity 43 of exhaust channel 49 with the lateral surface of the 1st motor cavity 41, and the chamber cover 45 that is arranged on the 1st, 2 motor cavities 41,43 upsides.
The 1st motor cavity 41 has columnar structured, is formed with the air discharge portion 46 that is communicated with the 2nd motor cavity 43.By air discharge portion 46, arrange to discharge chamber 47 by the air that fan electromotor assembly 30 is discharged.
One side of the 2nd motor cavity 43 penetratingly is connected with the 1st motor cavity 41 inside by air discharge portion 46.The opposite side of the 2nd motor cavity 43, with the 1st motor cavity 41 lateral surfaces across a certain distance state mutually, extend to discharge chamber 47.Thereby form exhaust channel between the 2nd motor cavity 43 and the 1st motor cavity 41.
Form the path that extends to discharge chamber 47 by the 2nd motor cavity 43, the air that fan electromotor assembly 30 is discharged is discharged to discharge chamber 47 directions.Be that the air that fan electromotor assembly 30 is discharged is not directly to arrange to discharge chamber 47, but discharge along the exhaust channel 49 that fan motor combination body 30 lateral surfaces form.Therefore, the distance of the air that fan electromotor assembly 30 is discharged increases, and the pressure of air descends, and can reduce air and discharge the noise that produces.In order to increase the effect that air pressure reduces, the 2nd motor cavity 43 is advisable with the structure that increases near the leaving area of discharge chamber 47.In addition, sound-absorbing material (figure slightly) is installed on exhaust channel 49, is improved the reduction noise result and be advisable.
In addition, on above-mentioned discharge chamber 47, be provided with can the contained foreign matter of filtered air discharge filter (figure slightly).This discharge filter adopts the fine filter that can filter minute dust to be advisable.
As shown in Figure 2, at the rear of motor cavity 40, winder 42 is installed.Above-mentioned winder 42 is used for reeling, depositing power line.Symbol 48 is the winder buttons that are used for control reeler, and arrow and 44 is air-flow directions.
Below operation principle of the present invention is described.
Exhaust channel 49, extends to the direction of discharge chamber 47 around the outside of fan electromotor assembly 30 by the structure of the 1st, the 2nd motor cavity 41,43.Thereby the air that fan electromotor assembly 30 is discharged is not directly arranged to discharge chamber 47 but along the outer footpath discharge that detours that is formed by exhaust channel, by increasing the path reduction noise of sound conduction.
Fig. 7 is the motor cavity part sectional structure schematic diagram of another embodiment of the present invention; Fig. 8 is the cross-sectional structural representation of Fig. 7; Fig. 9 is the vertical profile structural representation of Fig. 7.
Below with reference to Fig. 7 to Fig. 9 the motor cavity of another embodiment of the present invention is described.The symbology identical with Fig. 1 to Fig. 6 has the same parts of same function.
Extremely shown in Figure 9 as Fig. 7, another embodiment of the present invention has and is installed in the motor cavity 140 that main body of dust collector 10 inside are used to settle fan electromotor assembly 30, be connected with the 3rd motor cavity 141 of discharge chamber 147 in a side, and separated by a distance and be installed in the inboard with the 3rd motor cavity 141, can directly settle the 4th motor cavity 143 of fan electromotor assembly 30.
The 3rd motor cavity 141 is installed on the main body of dust collector 30, is formed with through hole 145 from air to discharge chamber 147 that can discharge.Through hole 145 has grid shape structure, can form a plurality of so that discharge air easily.
The 4th motor cavity 143 has cylindrical shape, so that directly settle fan electromotor assembly 30.The medial surface of the 4th motor cavity 143 and the 3rd motor cavity 141 is separated by a distance.Thereby, between the medial surface of the 2nd motor cavity 141 and the 4th motor cavity 143, can form the exhaust channel 149 of discharging air.
As shown in Figure 8, the fan electromotor assembly 30 that is installed in the 4th motor cavity 143 sucks air by driving, to the 4th motor cavity 143 belows with radial discharge.As shown in Figure 9, the air of discharge forms the exhaust pathway nearest with through hole 145 on the 1st position A, and with the 1st position A the 2nd position B in opposite directions on form the exhaust channel of ultimate range.
By the exhaust channel that the space that is separated by by the 3rd, the 4th motor cavity 141,143 forms, can make fan electromotor assembly 30 discharge the discharge of air apart from increase.Promptly the air of being discharged by the 1st position A is discharged with the shortest distance, and the air that the 2nd position B discharges is discharged with the distance of maximum, so average air exhaust distance obtains increasing the exhaust distance that can prolong air.By increasing the discharge distance of air, can increase the conduction distance of noise, reduce air pressure, thus the noise when easily reducing by 30 work of fan electromotor assembly.
