Description

The present invention relates to a pipe for manipulation and to a vacuum cleaner equipped with a pipe for manipulation, and more particularly, to a pipe for manipulation mounted with a cyclone dust collector, and to a vacuum cleaner having a handle.

A vacuum cleaner is an electric household device designed to clean the surface of dust and dirt, which provides for forced air circulation by turning the motor in rotation, so that a vacuum is created in the interior of the vacuum cleaner body, and dust and dirt are sucked into the device along with the intake air due to the intense flow resulting from the differential pressure created between the inner side and the outer side of the device, resulting o dust and dirt are removed.

In addition, the cyclone dust collector is a device designed to separate particles from the fluid by centrifugal force. Due to the advantage of simple construction and resistance to high temperatures and pressures, such a cyclone dust collector has been widely used for a very long time in industry, and is also used in a vacuum cleaner.

A typical example of a cyclone equipped with a cyclone dust collector is disclosed in Korean Patent Application No. 1999-20704, entitled "Cyclone Dust Collector for Vacuum Cleaner", which is pending and filed in the name of the assignee for this application.

Figure 1 is a perspective view showing a vacuum cleaner with a cyclone dust collector as described in the aforementioned patent application.

As can be seen from the drawing, a conventional vacuum cleaner 1 equipped with a cyclone dust collector 21 comprises a vacuum cleaner body 3, a flexible hose 9 connected to the vacuum cleaner body 3, an extension pipe 8, a manipulation pipe 7 located between the flexible hose 9 and the extension pipe 8 and connected to the flexible hose 9 and the extension pipe 8, and a cyclone dust collector 21 located between the manipulation pipe 7 and the extension pipe 8 and connected to the manipulation pipe 7 and to the extension pipe 8.

The housing 3 of the vacuum cleaner is divided into a dust collector (not shown), inside which a bag (not shown) for dust is placed, and a chamber (not shown) with a drive to create a load, in which an electric motor (not shown) is placed, designed to create a suction force to ensure the suction of air, which contains dust from the outside, into the dust collector.

The far end of the extension pipe 8 is connected to the brush 10, and the brush 10 is configured to come into contact with a surface to be cleaned, such as a floor covered with laminated paper and a carpet, and the bottom side of the brush 10 is made with an inlet.

A cyclone dust collector 21 is mounted between the manipulation pipe 7 and the extension pipe 8, attached to the manipulation pipe 7 and to the extension pipe 8, and provides for the separation of dirt, such as dust contained in the air, by centrifugal force.

The tube 7 for manipulation is made with a handle 4 on its side, so that the user can easily grab the tube 7 for manipulation.

When using the design described above when connecting the power source, air that contains dirt, such as dust, is sucked through the inlet of the brush 10 due to the suction force created by driving an electric motor designed to create a suction force. Air passes through an extension pipe 8 and passes into the dust collector 21. Dirt with a large particle size or scraps of paper is separated from the air by centrifugal force, when the air passing into the cyclone dust collector 21 forms vortex air flows and moves towards the closed end of the cyclone dust collector. Separated dirt, etc. lowers along the inner wall of the dust bag 25 and accumulates in the lower part of the dust bag.

The cleaned air moves through the pipe 7 for manipulation and a flexible hose 9 located between the pipe 7 for manipulation and the body 3 of the vacuum cleaner and connected to the pipe 7 for manipulation and the body 3 of the vacuum cleaner, and then enters the body of the vacuum cleaner.

The dust capture and collection processes performed in the dust collector (not shown) of the vacuum cleaner body are the same as those performed in the conventional vacuum cleaner 1.

However, in such a conventional vacuum cleaner, it is necessary to separately handle the handle for the pipe for handling, and, in particular, in the presence of a cyclone dust collector, the load acting on the side of the pipe for handling is concentrated unevenly in the direction of the cyclone dust collector. Therefore, it is difficult to smoothly move a vacuum cleaner having a pipe for handling.

In addition, in such a conventional vacuum cleaner, the suction driving force generated in the vacuum cleaner body acts on a long path of air movement including a brush, an extension pipe attached to the brush, a cyclone dust collector, a manipulation pipe attached to the cyclone dust collector , and a flexible hose located between the manipulation pipe and the vacuum cleaner body and attached to them, resulting in a partial loss of driving force. Therefore, there is a problem in that the dust collecting capacity of the cyclone dust collector is reduced.

An object of the present invention is to solve the above problems encountered when using known devices, i.e. the technical task of the present invention is to create a pipe for manipulation, designed for a vacuum cleaner, which has a simple design and which the user can easily grab when performing cleaning, and to create a vacuum cleaner equipped with such a pipe for manipulation.

Another technical objective of the present invention is to provide a lightweight manipulation pipe for a vacuum cleaner, which is provided with a handle-shaped duct for air flow passage, as a result of which there is no need for a separate handle, and to create a vacuum cleaner equipped with such a manipulation pipe.

Another technical objective of the present invention is to create a pipe for handling intended for a vacuum cleaner, which is made with such a handle-shaped channel for the passage of air flow, which, in turn, has a cyclone dust collector, and to create a vacuum cleaner equipped with such a pipe for handling .

These technical problems are solved due to the fact that the vacuum cleaner in accordance with the present invention contains a brush for suctioning air that contains dust from the external environment, a vacuum cleaner body for communicating a suction force to the brush, and a manipulation pipe connecting the brush and the vacuum cleaner body with such so as to allow air to pass through the manipulation pipe, the predetermined part of the manipulation pipe being made in the form of a handle to be gripped by the user, and the handle is made with two elbows between at the distal end to be attached to the brush, and the near end to be attached to the vacuum cleaner body, and a cyclone dust collector is mounted on the manipulation pipe, wherein the manipulation pipe body has first and second flow channels located lower and higher relative to the barrier wall in the pipe body for manipulation, the first flow channel being made with an air inlet opening in communication with the brush and a suction channel connected to the side of the cyclone dust collector in the rear Asti pipe manipulation.

Preferably, a knurled portion is formed on the outer surface of the handle.

Preferably, the cyclone dust collector comprises a cyclone collector body that swirls the air passing inside the manipulation pipe, separates dust by centrifugation, and removes dust; and a dust collector for collecting dust separated by centrifugation, wherein the dust collector is removably attached to the cyclone body.

Preferably, the cyclone trap body comprises a suction channel, by means of which a swirl of air containing dust and entering the pipe for manipulation is provided, an exhaust channel for discharging air from which the dust is separated, and a grating connected to the exhaust channel to remove dirt.

The technical problems are also solved due to the fact that the manipulation pipe for the vacuum cleaner according to the invention is located between the brush, which sucks air containing dust from the external environment, and the vacuum cleaner body, designed to communicate to the brush the suction force, and the manipulation pipe is made with a passage for passage air flow connecting the brush and the cleaner body, and with a handle that can be gripped by the user, and the handle is made with two elbows between the distal end to be connected insensibility to the brush, and the proximal end to be attached to the vacuum cleaner body, and a cyclone dust collector is installed on the manipulation pipe, while the manipulation pipe body has first and second flow channels located lower and higher relative to the blocking wall in the manipulation pipe body, moreover, the first flow channel is made with an air inlet opening in communication with the brush, and a suction channel connected to the side of the cyclone dust collector in the rear of the pipe for manipulation.

The above and other objectives, features and advantages of the present invention will become more apparent from the following detailed description with reference to the accompanying drawings, in which:

figure 1 is a perspective image of a conventional vacuum cleaner equipped with a cyclone dust collector in accordance with the prior art;

figure 2 is a side view of the pipe for handling intended for a vacuum cleaner according to the present invention, and the pipe for handling is made with a cyclone dust collector; and

figure 3 - cross section of the pipe for manipulation shown in figure 2.

Next, preferred embodiments will be described in more detail with reference to the accompanying drawings. In the following description of an embodiment of the present invention, similar positions are assigned to elements having the same structures and functions as in the conventional apparatus described above.

Figure 2 is a side view of the pipe for handling for a vacuum cleaner, and the pipe for handling is made with a cyclone dust collector. In particular, the manipulation pipe shown in FIG. 2 has a design that is improved so that the channel for the passage of air flow through the manipulation pipe is shaped so that it takes the form of a handle, as a result of which a separate handle is not required, and the pipe for manipulation will be easy. A vacuum cleaner equipped with a manipulation pipe that includes a cyclone dust collector comprises a brush 10, a vacuum cleaner body 3, a flexible hose 9 connecting the brush 10 and the vacuum cleaner body 3, a manipulation pipe 7 mounted between the flexible hose 9 and the brush 10, and an extension pipe 8 having a distal end attached to the brush 10, and a proximal end attached to the pipe 7 for manipulation. Since the housing 3 of the vacuum cleaner, flexible hose 9, extension pipe 8 and brush 10 are similar to the corresponding elements shown in figure 1, they are not shown in figure 2.

The housing 3 of the vacuum cleaner is divided into a dust collector (not shown), which is located inside the housing 3 of the vacuum cleaner and inside which a bag (not shown) for dust is placed, and a chamber (not shown) with a drive to create a load in which an electric motor (not shown) is placed, Designed to create a suction force to suck in air that contains dust from the outside into a dust collector.

The far end of the extension pipe 8 is connected to the brush 10, and the brush 10 is in contact with a surface to be cleaned, such as a floor covered with laminated paper or a carpet, and the bottom side of the brush 10 is made with an inlet.

A predetermined portion of the manipulation pipe 7 is provided with a handle 60 to be gripped by the user, so that the user can easily grasp the manipulation pipe 7.

A pipe for handling made with a cyclone dust collector is described with reference to FIG. 3. FIG. 3 is a sectional view illustrating a mounting structure of a cyclone dust collector. In the drawing, the letter I denotes the front side of the pipe for manipulation.

As can be seen from figure 2, the pipe 7 for manipulation contains a cyclone dust collector 21 mounted on the pipe 7 for manipulation, and the body 30 of the pipe for manipulation.

As can be seen from figure 3, the body of the pipe for manipulation has a first channel 39 for flow and a second channel 41 for flow, while the first and second channels 39, 41 for flow are located lower and higher relative to the blocking wall 53 in the body 30 of the pipe for manipulation.

The first flow channel 39 is provided with an air inlet 35 communicating with the brush 10 and made in the front of the manipulation pipe 7, and with a suction channel 37 connected to the side of the cyclone dust collector 21 in the rear of the manipulation pipe 7.

The second flow channel 41 is provided with an air outlet 47 communicating with a flexible hose 9, which is an air outlet, at the rear of the manipulation pipe 7, and an exhaust channel 43 connected to the cyclone trap 21 at the front of the manipulation pipe 7 .

The second flow channel 41 is designed as a two-elbow structure so that the handle grip space 65 is formed completely under the manipulation pipe 7 to allow the user to easily grab the manipulation pipe 7.

In addition, the second flow channel 41 is located at a certain distance from the dust collector 25 and is removed from it in the backward direction, so that the dust collector 25 can be connected to the cyclone dust collector body 55 with a possibility of detachment and removal. The distance "d" between the rear end of the dust collector 25 and the second flow channel 41 is determined so that it is possible to easily attach the dust collector 25 to the pipe 7 for manipulation or to disconnect it from the pipe 7 for manipulation.

Knurling may be formed on the outer surface of the handle 60 so that the user can securely hold the manipulation pipe 7 without slipping the manipulation pipe 7. Alternatively, a series of folds or protrusions with various shapes may be partially formed on the outer surface of the handle 60.

The cyclone dust collector 21 includes a cyclone trap body 55, as well as a dust collector 25, which is removably attached to the cyclone trap body 55.

The housing 55 of the cyclone trap has a suction channel 37, which is designed to suck in air and with the help of which the swirling of air containing dust and passing into the pipe 7 for manipulation is provided, the exhaust channel 43, designed to release air after separation of dust from it by centrifugation; and designed to separate the dirt lattice element connected to the exhaust channel 43 and made with many small passage holes 44.

Preferably, the cyclone trap body 55 has a cylindrical shape corresponding to the shape of the dust collector 25.

The dirt element 70 for separating dirt has a cylindrical shape with a plurality of small passage holes 44 formed on the circumferential periphery and an opening 45 formed at the end of the mesh element. The hole 45 is used to release air passing into the dedicated to the separation of dirt grating element 70 through the small passage holes 44.

In addition, the element 50, obstructing the flow in the opposite direction, extends from the dirt separating grating element 70 towards the bottom of the dust collector 25.

When the suction flow generated by the power source is applied to the manipulation pipe of the above construction, air containing dirt, such as dust, is sucked through the air inlet opening provided in the brush 10 under the action of the suction force created by the drive motor for creating suction force. After that, air enters the interior of the cyclone dust collector 21 through an extension pipe 8 connected to the brush 10.

The air entering the interior of the cyclone dust collector 21 passes into the interior of the cyclone dust collector 21 in an oblique direction along the suction channel 37 formed in the cyclone body 55. As a result, air that contains dirt, such as dust, forms vortex airflows and begins to move toward the closed end of the cyclone dust collector 21.

During this process, dirt with a large particle size or pieces of paper contained in the air are separated from the air by centrifugal force. Separated dirt falls along the inner wall of the dust collector 25 of the cyclone dust collector 21 and accumulates in the lower part of the dust collector 25 of the cyclone dust collector. The processes of capture and collection of dust, performed in a dust collector (not shown) in the housing 3 of the vacuum cleaner, are the same as those performed in a conventional vacuum cleaner 1.

The description of the embodiments described above is made for a pipe for handling carried out with a cyclone dust collector, and for a vacuum cleaner having a pipe for handling. However, there is no doubt that the present invention can be implemented as another option, namely in the form of a pipe for handling, having a handle without a cyclone dust collector, and in the form of a vacuum cleaner equipped with such a pipe for handling.

In accordance with the present invention, as described above, there is no need for a separate handle for the pipe for handling, and therefore a simple and light pipe for handling can be used. Therefore, the vacuum cleaner can be used in a convenient manner.

In addition, the “transmission” path of the suction driving force from the electric motor for generating the suction force and provided in the cleaner body can be shortened. Therefore, the dust collection efficiency provided by the vacuum cleaner can be improved.

Although preferred embodiments of the present invention have been shown and described with reference to preferred embodiments thereof, the present invention is not limited to these embodiments. It should be understood that various modifications and changes can be made by those skilled in the art without departing from the spirit and scope of the invention defined by the appended claims. It should be believed that all such modifications, changes and their equivalents are within the scope of the present invention.
