BACKGROUND of the INVENTION

1. The technical field

This invention relates to a vacuum cleaner. More specifically this invention relates to a cyclone unit for separating contaminants that can be applied in the vacuum cleaner and filters using centrifugal force involved with air pollution in at least two stages, and the cleaner that contains this device.

2. Description of the prior art

A cyclone unit for separating contaminants has a design, which in the chamber of the cyclone is formed a circular air flow for separating pollutants through the use of centrifugal force, the contaminants are caught and thrown out clean air. Recently, to improve the efficiency of trapping pollutants were presented multi-cyclone device that at least two-stage capture pollutants contained in the air.

Figure 1 and figure 2 are views showing one example of a cyclone unit for separating sagra is of distributors, described in the patent application Korea No. 2003-62520 filed on behalf of the same applicant. Figure 1 is a schematic view of a perspective view of a vacuum cleaner of the upright type, which uses a multi-cyclone unit for separating contaminants, and figure 2 is a view in axonometric exploded view of the device shown in figure 1.

In the main body 21 of the vacuum cleaner has a space 23 that is designed for the installation of the engine. To the underside of the main body 21 of the vacuum cleaner is attached to the suction nozzle 24, and in the center of the front side of the main body 21 of the vacuum cleaner has a Department of 22 intended for the installation of the cyclone. On the other hand, on the back side branch 22, intended for installation of the cyclone made the channel 25 to the suction air channel 26 for the release of air flowing essentially in the vertical direction. When installing the multi-cyclone apparatus for separating contaminants in the compartment 22, intended for installation of the cyclone, the suction channel 25 and the Issuer of the channel 26 are communicated respectively with the tube 11 air inlet and a pipe 12 for air release.

Refer to figure 2. Multi-cyclone unit 10 for separating pollutants contains the first cyclone 13, designed for pre-trapping pollutants from venutolo who is an ear, and a few second cyclones 14 located on the periphery of the first cyclone 13, surrounding it. In addition, the device 10 includes a window 15 for air vent in the top wall of the first cyclone 13 and second cyclones 14, intake/exhaust cover 17 connecting with each other window 16 air inlet of the second cyclone 14, cover 18 cyclones located on the intake/exhaust cover 17 and has made it the tube 12 for venting, and the casing 19 to trap contaminants separated from the air in the first cyclone 13 and the second cyclones 14.

The following describes the operation of the device 10 and the operation of the vacuum cleaner that contains this device.

First, when you create in the main body 21 of the vacuum cleaner suction effort of the air containing the contaminants, passes through the suction nozzle 24 and channel 25 for suction of air, and then through the tube 11 to inlet air enters the device 10.

The air that has passed through the inlet tube 11, flows into the first cyclone 13 in the tangential direction. When lowering the air forms a circular flow, and large contaminants separated from the air and trapped in the casing 19 to trap pollutants. The air, which is separated major pollutants, rises again and is thrown through a window 15 for venting the first cyclone 13. Then the air passes through the who is unaproved (not shown) inlet/outlet cover 17 and enters each of the second cyclone 14 through the window 16 for air intake. The air in the second cyclone 14 again forms a circular flow and fall, small contaminants separated from the air is collected in the casing 19 to trap pollutants.

The air, which is separate fine contaminants, rises and passes through each exhaust passage 17A of the intake/exhaust cover 17, and then is collected in the cap 18 cyclones. Through the tube 12 for air release, made on the cover 18 of the cyclone, the air is emitted to the outside of the multi-cyclone device 10 for separating pollutants. After that, the air passes through the channel 26 to release air and space 23 that is designed for the installation of the engine, and then is emitted to the outside from the main body 21 of the vacuum cleaner.

However, the conventional multi-cyclone unit for separating contaminants above construction has the following disadvantages.

First, the tube 11, through which air is getting made on the upper side wall of the first cyclone 13 and second cyclones 14 and the tube 12, through which the discharged air, in the General case is made in the top or in the side section of the cover 18 cyclones, closing the first cyclone 13 and the second cyclones 14. However, since the above structure causes problems, is to increase the total height of the multi-cyclone device 10 for separating pollutants, with the creation of a compact vacuum cleaner, container type is difficult.

Secondly, the engine used in the vacuum cleaner, in particular in a vacuum cleaner of the upright type, has a very large weight, so the space 23 that is designed for the installation of the engine, usually located on the bottom side of the main body 21 of the vacuum cleaner. Therefore, the space 23 that is designed for the installation of the engine, is located on the bottom of the compartment 22 for installation of the cyclone. On the other hand, since the tube 12 for air release is located in the upper part of the multi-cyclone device 10 for separating pollutants, the channel 26 for venting connecting the space 23 that is intended to be fitted with a pipe 12 for air release must have a greater length. As a result of increasing loss of suction force generated by the engine, and therefore increases the pressure drop. In addition, the complicated internal structure of the main body 21 of the vacuum cleaner.

DETAILED DESCRIPTION of EXAMPLES of IMPLEMENTATION

Below with reference to the accompanying drawings described multi-cyclone unit for separating contaminants and a vacuum cleaner that uses this device, made in accordance with a preferred variant of the present invention.

In the following description for the same elements use the same notation even in different drawings. The objects specified in the description, such as detailed construction and elements are provided only to facilitate a comprehensive understanding of the invention. Thus, it is obvious that this invention can be made without specifying these objects. In addition, not detailed the Scriptures known functions or constructions, since the presence of excessive detail would confuse the invention.

Figure 3 is a view of a perspective view of the multi-cyclone unit for separating contaminants carried out in accordance with the exemplary embodiment of the present invention, figure 4 is a view in axonometric exploded view of the device shown in figure 3, and figure 5 is a top view of the housing of the cyclone shown in figure 4.

Multi-cyclone device 100 for separating pollutants is shown in figure 3-5, includes a housing 110 cyclones, which includes the camera 111 of the first cyclone and the second camera 121, engaged in two-stage separation of contaminants from air, venutolo outside; inlet/exhaust cover 130 and the cover 140 cyclones, United with the upper end of the housing 110, and the cover 160 to trap pollutants connected with the lower section of the housing 110. In addition, the device 100 includes an exhaust conduit 150, designed to channel air ejected from the camera 121 of the second cyclones, to the lower end of the casing 160 to trap pollutants.

The camera 111 of the first cyclone is made in the center of the housing 110, the air and the pollutants involved from the outside, form a swirling flow of air and separated from each other in the chamber of the first cyclone due to centrifugal force. The camera 111 of the first cyclone contains Jindrisska outer wall 112 and the window 113 for air release, through which emits air. The upper section of the outer wall 112 of the chamber has an aperture forming the inlet box 115, through which the chamber 111 of the first cyclone passes outside air. The incoming air moves along the guiding element 114 and is lowered into the chamber of the first cyclone 111. At this time, centrifugal force acts on the contaminants that are heavier than air, so that the pollutants accumulate and act on the inner surface of the outer wall 112 of the first chamber, and the final capture of pollutants occurs in the casing 160 to trap pollutants. As a relatively lightweight air is exposed to a small centrifugal force, it is collected in the Central part of the chamber 111 of the first cyclone, creating turbulence, and thus rises and forms a flow of vent air in the direction of the outlet port 113 to release the air and then thrown away. Because pollutants can act in the opposite direction due to the rising air stream, on the wall of the lower end of the window 113 has a lattice element 116 that is designed to prevent the passage of contaminants in the opposite direction.

The housing 110 also has an outer wall 122 of the second camera having a certain thickness and a surrounding outer wall 112 of the first chamber, and a few who Amer 121 of the second cyclones, made in the outer wall of the second cameras and designed for the secondary recovery of pollutants from the air emitted from the chamber 111 of the first cyclone. As shown in the drawings, in contrast to the outer wall 112 of the first chamber outer wall 122 of the second camera does not have a cylindrical shape. On one side of the outer wall 122 of the second camera has an aperture passing in the radial direction and forming a window 115 for air release. In the space intended for the education of the window 115, the camera 121 of the second cyclone is missing. The air passing into the chamber 121 through the window 123 for air intake, rotates and forms a descending air flow, and small contaminants separated from the air and then catch them in the casing 160 to trap pollutants. The air separated due to centrifugal force, as described above, again forms a rising stream and ejected from the camera 121 of the second cyclone through the exhaust guide passages 132, located in the intake/exhaust cover 130.

The lid 130 made of an inlet guide passages 131 and the exhaust guide passages 132. The air emitted through the window 113 for release of air from the chamber 111 of the first cyclone, collides with the upper end of the cover 130 and passes through the several inlet guide passages 131 in the hole 123 for air intake. If the cover 130 to connect the s with the housing 110, some part of each passage 132 is included in the corresponding camera 121 of the second cyclone. Therefore, the air and the contaminants are separated from each other in the chambers 121, and then the air is discharged through the passages 132.

Cover 140 cyclones made on the upper side of the cover 130. The air emitted through the exhaust guide passages 132, going in the cover 140, and then flows into the exhaust conduit 150 through the inlet 154 of the guide channel located in the cover 130.

The outlet channel 150 directs the air ejected from the camera 121 of the second cyclones, to the lower end of the casing 160 to trap pollutants. Channel 150 includes the first conduit 151 made in the outer wall 122 of the second chambers, a second conduit 153 made in the casing 160 and the inlet 154 of the guide channel formed in the lid 130. Here through the outer wall 122 of the second camera and the casing 160, essentially in the vertical direction are respectively the first conduit and the second conduit.

The first conduit 151 communicates with the inlet 154 of the guide channel, the upper end of which is located on the lid 130. The channel 151 is formed in the region of the outer wall 122 of the second camera, which lacks a camera 121 of the second cyclone, and is located on one side with vypuskni the window 115. As shown in figure 5, through the outer wall 122, essentially in the horizontal direction passes the inlet window 115, and essentially in the vertical direction passes the inlet port 154 of the guide channel. Consequently, the flow of air received at the inlet window 115, and the air flow is received in the channel 151, meet at an angle of between about 80° up to about 100°and preferably at an angle of 90°. The upper end of the second guide channel 153 is in contact with the lower end of the first guide channel 151, and the lower end of the channel 153 is in contact with the inlet 230V space 230 for the installation of the engine (see Fig.6), which is located in the main body 210 of the vacuum cleaner.

The air emitted from the multi-camera 121 of the second cyclones flows from each outlet guide passage 132, and then is collected in the cap 140 cyclones. After that, the collected air collides with the upper end of the cover 140, and is then dissipated to the inlet 154. The air passes through the first 151 and 153 second guide channels and is discharged out of the device 100.

In the above-described multi-cyclone device 100 for separating contaminants carried out in accordance with this invention, the exhaust conduit 150 is held essentially in the vertical direction in the outer wall 122 of the second camera and the skin is e 160 to trap pollutants, and the air is ejected from the camera 121 of the second cyclones is directed to the exhaust guide channel 150 and is discharged in the direction of the lower end of the casing 160. In the conventional multi-cyclone unit for separating contaminants shown in figure 1, the tube 12 for air release is made on the top or side section of the cover 18 of the cyclone, so that the total height of the multi-cyclone apparatus for separating contaminants increases. However, the present invention can be applied to multi-cyclone unit for separating contaminants that have the desired compact design. The result of this invention is to simplify the design of cleaner, detailed description of which is given below.

Figure 6 shows the vacuum cleaner of the upright type having a multi-cyclone unit for separating contaminants carried out in accordance with a variant of the present invention. As shown in the drawing, a device 100 installed with the ability to attach/detach to the Department 220 for installation of a cyclone in the main body 210 of the vacuum cleaner. In addition, there is space 230 for the engine to be used as a means of obtaining the suction efforts and is installed on the bottom side of the compartment 220. In the General case, the space 230 for the installation of the engine is on the bottom side of the main body is 210, since the engine has a lot of weight. On the rear side of the compartment 220 is formed a passage 250 to the suction of the air through which the inlet window 115 of the device 100 is communicated to the suction air nozzle 240.

As shown in Fig.6, when installing the device 100 in the compartment 220 of the lower part of the discharge guide channel 150 communicates with the space 230. As described above, from the air received by the device 100 through the inlet box 115, removes pollutants and the air from which the removed contaminants, passes into the exhaust conduit 150, and then is ejected from the lower end of the casing 160. The ejected air enters directly into the space 230 of the main body 210. Here the direct flow of air into the space 230 means that the air does not pass through the passages for separate threads, but directly in the space for installation of the engine. Therefore, there is no need to create an exhaust duct 26 (see figure 1)that serves for directing air emitted from the conventional multi-cyclone devices in space 230, and it is possible to minimize the length of the exhaust duct 26. Therefore, the simplified internal structure of the main body 210, and the loss of suction efforts in the passage of the flow can be minimized.

The above-described multi-cyclone condition the device for separating pollutants are given as one example. However, this invention is not necessarily limited to this example. That is, it goes without saying that the invention is applicable to odnoekrannomu device for separating contaminants. In this case, the cyclone body includes a camera cyclone designed for centrifugation of contaminants from the incoming air, the inlet window, such as a suction box that is intended to cause the flow of external air into the chamber of the cyclone, and the outlet box designed to release from the chamber of the cyclone air not containing pollutants. Casing to trap pollutants connected with the lower part of the body of the cyclone. The exhaust conduit runs essentially in a vertical direction through the cyclone body and the casing to trap pollutants and thus the air emitted from the outlet port is directed to the lower end of the casing to trap pollutants. Odnotonnoe device for separating contaminants having the above structure can provide the same results that are obtained when using the multi-cyclone apparatus for separating contaminants above-described type.

On the other hand, in this embodiment shown is only an example of how a cyclone unit for separating contaminants used in the vacuum cleaner is slight pressure from the beginning type, it goes without saying that the invention is not limited to this type of vacuum cleaners, and can be applied in the vacuum container type.

As described above, according to this invention through the inner space of the cyclone unit for separating contaminants, essentially in the vertical direction passes the air from which the removed contaminants, and then this air is ejected from the bottom of the casing to trap pollutants in the space for installation of the vacuum cleaner motor and, thus, decreases the height of the cyclone unit for separating contaminants simplified internal structure of a vacuum cleaner and can be reduced in pressure drop.
