The present invention relates to a vacuum cleaner and method of reducing noise generated them, and more particularly to a vacuum cleaner, which has a channel for the release of the flow and the vent filter is optimally located to reduce noise.

Usually the vacuum cleaner is a device that cleans the room so that foreign particles such as dust and dirt are sucked together with air into the housing through the creation of a suction force and is removed through a dust collection device and the like in the body.

As shown in figure 1, a conventional vacuum cleaner includes a housing 1 defining its appearance, node 2 blower fan located in the housing 1, to create suction power and dust collection device 3 for filtering contaminant particles from the intake air into the housing 1. The cleaner works in such a way that creates a suction force node 2 blower fan for intake pollutants, such as dust, together with air into the housing 1, and only air comes out of the body by filtering pollutants out of the air with dust collection device 3 located in the housing 1, thereby cleaning the room.

Node 2 blower fan conventional vacuum cleaner includes blower fan 2a to create a suction force in rotation and El is tradigital 2b to rotate the blower fan 2a. Blower fan 2a and the electric motor 2b are mounted so that their axis of rotation is located in the longitudinal direction in the front and rear direction, so that air is sucked from the front side, and then goes to the back. After passing to the rear of the air is directed along channel 6 for the release of the flow passes through the air filter 5 and then comes out of the housing 1 through the opening 4 for the air vent located in the top rear of the housing 1.

In such a vacuum cleaner due to various reasons creates noise. Specifically, the noise generated during the rotation of the electric motor 2b, the noise generated during the passage of air in the vent filter 5 through the channel 6 to release the flow and noise generated due to the friction between the air flowing at high speed in the channel 6 to the release thread, and the pipe 7 forming channel 6 for the release of the stream are reasons for most of the noise generated by the vacuum cleaner.

However, the conventional vacuum cleaner has the disadvantages that, since the length of the channel 6 for the release of flow from the outlet 8 of the node 2 blower fan to the 4 holes for air release is short, the noise generated during the rotation of the electric motor 2b is transmitted to the outside of the housing 1 without sufficient reduction, and because the distance from duhovyonoj filter 5 to the 4 holes for air release is also short, the noise generated by the airflow in the vent filter 5 through the channel 6 for output stream is also passed out of the housing 1 without sufficient reduction.

Details will be described embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Options for implementation are described below to explain the present invention with reference to the drawings.

As shown in figure 2, the vacuum cleaner in accordance with a preferred implementation of the ia of the present invention contains the suction unit 11 for suction of polluting particles together with air by the suction force and the housing 10 for collecting contaminant particles, suction suction node 11.

The body 10 and the suction unit 11 is connected by means of a connecting hose 12 and the connecting tube 13 to the suction force generated in the housing 10, passed through them in the suction unit 11. A vacuum cleaner equipped with a handle 14 between the connecting hose and the connecting tube 13 to be gripped by the user when using the vacuum cleaner.

Connection hose 12 is made of a stretchable corrugated tube and the like. Connection hose with one end connected to the housing 10, and the other end connected to the handle 14 so that the suction unit 11 can freely move within a given radius of the housing 10. Connecting tube 13 has a predetermined length and connected at one end with the suction node 11, when connected at the other end with a handle 14 to allow the user to clean the floor using a vacuum cleaner, standing on the floor.

As shown in figure 3 and 4, the housing 10 is connected on the front side with connection hose 12 for the passage of air through the connection hose 12, and the rear upper part of the housing 10 is formed by a hole 15 for the discharge of the air through which, after removal of pollutants using dust collection device 20 in the housing 10, the air comes out of the housing 10. The housing 10 has an internal part of the section is to nnuu on dust compartment 10a, containing dust-collecting device 20 located therein, the suction compartment 10b containing the node 30 blower fan and channel 16 for output stream located in it, as well as the Department 10s for AC power adapter with power cord (not shown)located therein.

Dust-collecting device 20 is located in the dust compartment 10a to collect dust sucked into the dust collection compartment 10a through the connection hose 12. In accordance with the embodiment dust-collecting device 20 is implemented using a cyclone device that separates particles from the air sucked into the dust-collecting device 20 using centrifugal force. However, it should be noted that the present invention is not limited to the cyclone device, and as a dust collection devices can be used in any type of dust bag that can collect dust. Dust compartment 10a includes a cover 21, pivotally attached to the upper part of the dust separation 10a to provide the installation with dust removal device 20 in the dust compartment 10a.

Node 30 blower fan creates a suction force in the vacuum cleaner and installed in the suction compartment 10b so that the axis of rotation of the node 30 blower fan is located is it in the direction of the bottom-up. Node 30 blower fan provides air-blowing fan 31 to create a suction force and a motor 32 for rotating the blower fan 31. Node 30 blower fan has an internal part, divided by the air-blowing portion 30a, which is a blower fan 31, and the drive portion 30b, in which is located the motor 32. The suction side of the node 30 blower fan communicates with the exhaust side dust collection device 20 through the connecting tube 17 to create a suction force in the dust collection device 20.

In accordance with this embodiment the blower fan 31 node 30 blower fan is a centrifugal fan that sucks the air in the axial direction and then release him in the radial direction. With this design the air coming from the blower fan 31, cools the motor 32 when passing through the drive portion 30b and then extends in a radial direction through multiple exhaust holes 34 formed on the outer periphery of the housing 33 of the motor surrounding the motor 32.

After exiting through the outlet opening 34 of the node 30 blower fan air passes through the inner flow channel 41 formed in the housing 40 surrounding the site 30 blower fan, and exits through the outlet 42, is made in the lower part of the node 30 of the blower fan. Then the air passes into the hole 15 for the release of air on channel 16 for the release thread. Here, under the channel 16 to issue flow refers to the flow channel of air from the exhaust holes 42 of the node 30 blower fan to the hole 15 for air release. In accordance with the present invention, the space formed between the dust collection unit 20 and node 30 blower fan is part of the channel 16 for output stream.

Channel 16 for output stream is bent several times and contains the first channel 16a of the stream, which is formed from the exhaust holes 42 of the node 30 blower fan to the space between the dust collection unit 20 and node 30 blower fan, the second channel 16b flow, which passes from the first channel 16a of the flow and is formed in the space between the dust collection unit 20 and node 30 blower fan, and the third channel 16c flow from the second channel 16b flow through the holes 15 for air release.

Essentially, unlike conventional vacuum cleaner, in which the residual space formed between the dust collection unit 20 and node 30 blower fan is unused space, the present invention uses the space about azowano between them, as part of the channel 16 for output stream and thus provides a sufficient length of channel 16 for production flow to ensure sufficient reduction of noise generated by the motor 32, without increasing the size of the housing 10.

The vent filter 18 is installed in the channel 16 to the release thread for filtering contaminant particles that have not been filtered dust collection device 20. Preferably the vent filter 18 is installed in the first channel 16a stream or the second channel 16b of the stream.

That is, when the air filter 18 is installed in the first channel 16a stream or the second channel 16b flow can be obtained a sufficient distance from the air filter 18 and the holes 15 for air release. With this design, the air passes through the air filter 18 having a sufficient length, and extends through a hole 15 for the exhaust, thus providing sufficient noise reduction.

In addition, since the vent filter 18 is installed in the first channel 16a stream or the second channel 16b flow having a relatively large cross-sectional area, it is possible to provide a sufficient area of the air filter 18, thereby reducing the pressure loss occurring when the airflow through the air filter 18. In this regard, the minimi is then pressure loss, taking place during the passage of air through the air filter 18 in the channel 16 to release the flow, it is desirable that the vent filter 18 was installed in place of the channel 16 to release the thread in which the channel 16 for output stream has the greatest cross-sectional area.

The cross-sectional area of the first channel 16a stream or the second channel 16b of the flow exceeds the cross-sectional area of the outlet 42 of the node 30 blower fan, and the cross-sectional area of the outlet 42 of the node 30 blower fan exceeds the cross-sectional area of the holes 15 for air release. Preferably the outlet 42 of the node 30 blower fan has an area of 7000 mm2or more, and a hole 15 for the air vent has an area of 7000 mm2or less.

In other words, the cross-sectional area of the channel 16 to release the flow gradually increases and then decreases from the outlet 42 of the node 30 blower fan to the hole 15 for air release. On the exhaust side of the channel 16 to issue flow fixed sound-absorbing material to absorb noise. That is, the channel 16 for output stream has a design that can grow to resonate and absorb noise, as in the muffler of the vehicle and thus znachitelyonaja noise, generated in the housing 10.

Since the dust-collecting device 20 is a cylindrical cyclone device, the second channel 16b of the flow channel 16 for production flow mainly formed on both sides of the dust collection device 20, as shown in figure 4.

Because the vent filter 18 is mainly installed in the first channel 16a stream or the second channel 16b flow, the housing 10 has an opening 50, which is formed in the bottom surface 19, to change the air filter through it, and is opened or closed by a door 51, as shown in figure 5.

In order for the door 51 is easily opened and closed, one side is fixed on the hole 50 by a hinge 51a and connects with him on the other side with a hook 51b.

As can be seen from this description, the vacuum cleaner in accordance with the present invention has a sufficient length of the channel for the release of flow, so that the noise generated by the motor, a sufficiently reduced at the exit of the air through the hole to release the air after passing along the channel for output stream.

In addition, the vent filter is located at a given distance from the outlet openings of the air, so that the noise created by the passage of air through the vent filter is sufficiently mitigated.
