Description

The present invention relates to a vacuum cleaner and, more particularly, to a vacuum cleaner in which the volume for collecting contaminants can be increased and the discharge of collected contaminants is easy.

Typically, a vacuum cleaner is a device that can suck in air containing contaminants using the suction force created by an electric motor installed in the main body and filter out the contaminants in a device for filtering contaminants.

Vacuum cleaners are divided into container and vertical. A container-type vacuum cleaner comprises a main body and a suction nozzle connected to the main body using a connecting tube. The container-type vacuum cleaner contains a main body and a suction nozzle, made as a whole with the main body.

In addition, a dust collector installed in a cyclone vacuum cleaner separates the contaminants from the air using the principle of the cyclone, and the air from which the pollutants are removed is discharged from the main body.

In recent years, in order to increase the efficiency of collecting contaminants, a multi-cyclone dust collecting device comprising a plurality of cyclone devices has been proposed.

That is, the multicyclone dust collecting device comprises a dust collecting body defining an appearance, a first cyclone device for separating relatively large pollutants contained in the air, and a second cyclone device for separating relatively small polluting particles contained in the air.

Contaminant particles separated by the first and second cyclone devices are collected in the respective first and second dust collecting compartments formed in the dust collecting casing.

A conventional dust collecting device comprises both a first and a second cyclone device.

A dust collector for discharging collected pollutants is detachably mounted in the main body.

However, since a conventional dust collecting device comprises both a first and a second cyclone device, the space for the main compartment has a reduced structure. Therefore, the volume for collecting contaminants in the main compartment is reduced, and thus the user has to empty the dust collector more often.

In addition, since a conventional dust collector comprises both a first and a second cyclone, the weight of the dust collector increases and, therefore, it is difficult for a user to handle the vacuum cleaner when installing the dust collector or unloading the collected contaminants.

In this case, the interior of the room may again become contaminated during the process of disconnecting the dust collector from the main body to empty the dust collector or discharge contaminants from the dust collector. Thus, there is a need for re-cleaning the room.

Therefore, the present invention relates to a vacuum cleaner, which essentially eliminates one or more problems due to limitations and disadvantages of the prior art.

An object of the present invention is to provide a vacuum cleaner that has a simple structure while increasing the volume for collecting contaminants.

Another objective of the present invention is to provide a vacuum cleaner from which collected contaminants can be easily unloaded.

Additional advantages, objectives and features of the present invention will be partially discussed in the following description, and partially understood by those skilled in the art after studying it, or may be studied through the practice of the present invention. The objectives and other advantages of the present invention can be realized and achieved due to the design specifically indicated in the description and claims, as well as in the accompanying drawings.

To achieve these goals and other advantages, and in accordance with the purpose of the present invention, as depicted and broadly described herein, a vacuum cleaner comprises: a main body accommodating a device for generating a suction force; a dust collecting device mounted detachably in the main body and comprising a first cyclone device for separating contaminants; a second cyclone device mounted on the main body; and an air outlet formed on the main body and discharging air to the outside of the main body separated in the second cyclone device.

In another aspect of the present invention, a vacuum cleaner is described, comprising: a main body accommodating a suction device for sucking in external air containing contaminants, and an air exhaust device for discharging air cleaned from contaminants; a dust collecting device mounted detachably in the main body and connected to the suction device; a first cyclone device mounted on a dust collector for separating contaminants; a second cyclone device installed in the main body, for re-separation of pollutant particles from air passing through the first cyclone device; and a plurality of dust collecting compartments for collecting particulate matter removed from the first and second cyclone devices.

Said vacuum cleaner has the following advantages.

Firstly, since the first cyclone device is provided on the dust collecting device, while the second cyclone device is separated from the dust collecting device and made on the main body assembly, the design of the dust collecting device is simplified and facilitated. Therefore, it is more convenient for the user to handle such a dust collecting device.

Secondly, although the second cyclone is separated from the dust collector, contaminants removed from the second cyclone are nevertheless collected in the dust collector. Therefore, only the dust collector is disconnected from the main body assembly and emptied.

Thirdly, since the second dust collecting device for collecting the pollutants separated by the second cyclone device is mounted on the outside of the first dust collecting unit for collecting the polluting particles separated by the first cyclone, the size of the first dust collecting device increases, thereby maximizing the collection volume polluting particles.

Fourth, since the dust collector is detached from the main body in the position in which it is closed, re-contamination of the interior of the room as a result of unloading of polluting particles is excluded when opening the lid member at a place where the user wants to unload the polluting particles.

Fifth, since the cover element provided in the upper part of the dust collecting device is designed to simultaneously open and close the first and second dust collecting devices, it is possible to efficiently unload the collected contaminants.

You must understand that both the specified General description and the following detailed description of the present invention are illustrative and explanatory and are intended to provide an additional explanation of the present invention, as claimed.

As shown in FIGS. 1-3, the vacuum cleaner 10 comprises a main body 100 and a dust separation device for separating contaminants contained in the air drawn into the main body 100.

The vacuum cleaner 10 further comprises a suction nozzle for suction of air containing contaminating particles, and a connecting tube for connecting the suction nozzle to the main body 100.

Since the design of the suction nozzle and the connecting tube is similar to the construction of the known suction nozzle and the connecting tube, their detailed description will be omitted.

The suction portion 110 of the main body is formed on the front lower end portion of the main body 100 for sucking air from a suction nozzle (not shown) into the main body 100.

An air outlet portion 120 of the main body is formed on a side surface of the main body 100 to release air separated from the contaminants.

In addition, the handle 140 of the main body is formed on the upper part of the main body 100.

A guide cover 160 is connected to the rear of the main body 100 to direct air from which contaminants are removed by a dust separator to the main body 100.

In addition, the dust separation device comprises a dust collecting device 200 for first separating the pollutants contained in the air, and a second cyclone device mounted on the main body 100 for the second separation of the polluting particles from the air, from which the polluting particles are first separated in the dust collecting device 200.

The dust collecting device 200 is installed with the possibility of separation in the front of the main body 100. As described above, for installing with the possibility of separating the dust collecting device 200 on the main body 100, a lever 142 for installing / disconnecting is provided on the handle 140 of the main body 100, and on the dust collecting device 200 an engaging end 256 is made, engaged with a lever 142 for mounting / disconnecting.

The dust collecting device 200 comprises a first cyclone flow generating device and a dust collecting body 210 comprising a dust collection in which contaminants collected by the first cyclone are collected.

In this case, the dust collecting device 200 is installed with the possibility of separation on the main body 100 and communicates with the second cyclone device 300 and the main body 100 when installing the dust collecting device 200 on the main body 100.

The main body 100 is provided with an air outlet 130 for discharging air drawn into the main body 100 to the dust collector 200. The dust collector 200 is provided with a first suction port 212 through which air is sucked from the air outlet 130.

In this case, the first suction opening 212 is formed in the tangential direction of the dust collecting device 200 to form a cyclone flow therein.

The dust collecting device 200 is provided with a first air outlet 252 through which air is discharged from which the contaminants are separated in the first cyclone device. The main body 100 has a connecting channel 114 for directing air leaving the first air outlet 252 to the second cyclone device 300.

In addition, the second cyclone device 300 comprises a plurality of small cyclones that are cone-shaped. Small cyclones are connected in parallel.

The second cyclone device 300 is located horizontally in the rear upper part of the main body 100. That is, the second cyclone device 300 is located at a predetermined angle relative to the main body 100.

As described above, with the horizontal arrangement of the second cyclone device 300 on the main body 100, the efficiency of using the space of the vacuum cleaner provides for the location of the vacuum motor.

Since the second cyclone device 300 is separated from the dust collector 200 and mounted on the main body 100, the structure of the dust collector 200 is simplified and lightweight. Therefore, the user can easily handle the dust collector 200.

In this case, the contaminants separated by the second cyclone device 300 are collected in the dust collecting device 200.

Therefore, the dust collecting case 210 is provided with an aperture 254 for sucking in pollutant particles, through which the polluting particles separated by the second cyclone device 300 are sucked, and a dust collecting compartment in which the polluting particles collected by the second cyclone device 300 are collected.

That is, the dust collecting compartment formed in the dust collecting housing 210 includes a first dust collecting compartment for collecting polluting particles separated by a first cyclone device, and a second dust collecting compartment for collecting polluting particles separated by a second cyclone device 300.

That is, in the present embodiment, although the second cyclone device 300 is separated from the dust collector 200 and mounted on the main body 100, contaminants separated in the second cyclone device are collected in the dust collector 200.

In this case, the second cyclone device 300 can be tilted down towards the dust collecting device 200, so that the separated contaminants can be efficiently directed to the dust collecting device 200.

Below will be described the operation of this vacuum cleaner 10.

Firstly, when the electric power is supplied to the vacuum cleaner 10, the vacuum motor creates a suction force, and thus, air containing contaminants is absorbed into the suction nozzle under the action of the created suction force. Air passing into the suction nozzle is directed to the dust collector 200 through a channel formed in the main body.

When air containing pollutants is sucked into the dust collector 200, the pollutants are first separated in the first cyclone device. The separated pollutants are collected in the dust collecting case 210. On the other hand, the air from which the polluting particles are separated leaves the dust collecting device 200 and passes to the main body 100. Then, the air is sent to the second cyclone device 300 through the connecting channel 114 provided in the main body one hundred.

The contaminants contained in the air passing to the second cyclone device 300 are further separated and the separated pollutants pass and collect in the dust collector 200. Then, the air ultimately exits through the air outlet portion 120 of the main body through a channel formed in the main body 100.

Below will be described in more detail dust collecting device 200.

Figure 4 is a sectional view along the line I-I 'in Figure 3, and Figure 5 is a sectional view along the line II-II' in Figure 3.

As shown in FIGS. 4 and 5, the dust collector 200 comprises a dust collector body 210 defining an appearance, a first cyclone device 230 selectively mounted in the dust collector body 210 and separating pollutants contained in the air, and a lid member 250 for selectively opening and closing the upper part of the dust collecting case 210.

The dust collecting case 210 is made in a cylindrical shape and forms a dust collecting compartment for collecting the separated pollutants.

The dust chamber comprises a first dust chamber 214 for collecting contaminants separated in the first cyclone device 230, and a second dust chamber 216 for collecting contaminants separated in the second cyclone device 300.

In this case, the dust collecting case 210 comprises a first wall 211 forming a first dust collecting compartment 214, and a second wall 212 forming a second dust collecting compartment 214. That is, the second wall 212 is intended to cover part of the first wall 211.

Accordingly, the second dust collecting compartment 216 is formed on the outside of the first dust collecting compartment 214.

As described above, when the second dust collecting compartment 216 is formed on the outside of the first dust collecting compartment 214, the size of the first dust collecting compartment 214 can be maximized to increase the volume for collecting contaminants of the first dust collecting compartment 214.

The first wall 211 is made with a step 219 around the circumference of the circle to maintain the lower end of the first cyclone device 230 mounted on it. Therefore, with respect to the circumferential step 219, the upper part of the first dust collecting compartment 214 has a larger diameter than the diameter of the lower part.

A pair of pressure plates 221 and 222 are provided on the dust collecting case 210 to reduce the amount of contaminants collected in the first dust collecting part 214, and thus increase the volume for collecting the contaminants.

In this case, a pair of pressure plates 221 and 222 act relative to each other in order to compress the contaminants to reduce the volume of contaminants. Therefore, the density of the pollutants collected in the first dust collecting compartment 214 increases, the maximum volume for collecting the polluting particles of the first dust collecting compartment 214 increases.

The pressure plate 222 may be a fixed plate mounted on a mounting axis 224 located at the bottom of the dust collecting case 210. The pressure plate 221 may be a rotation plate fixed on a rotation axis connected to the mounting axis 224.

The driven mechanism 228 is connected to the axis of rotation 226 for rotation of the leading source.

In this case, the main body 100 is provided with a drive mechanism engaged with the driven mechanism 228, and a drive motor for driving the drive mechanism.

Therefore, when the drive motor is driven, the drive mechanism and the driven mechanism 228 rotate and rotate the rotary plate 221 as a result of rotation of the driven mechanism 228.

In this case, the rotary plate 221 can rotate in both directions in order to compress contaminants on both sides of the fixed plate 222. Accordingly, the drive motor may be a synchronous motor.

In the present embodiment, although one of the pressure plates 221 and 222 is rotatable in the dust collecting case 210, the present invention is not limited to this embodiment. For example, both the pressure plate 221 and the pressure plate 222 may be rotatable in the dust collecting case 210.

In addition, the dust collecting case 210 is opened in the upper part, so that the user can discharge contaminants by flipping it. The lid member 250 is removably coupled to the upper portion of the dust collecting case 210.

In order to discharge contaminants from the dust collecting case 210, the first cyclone device 230 is disconnected together with the lid member 250. Therefore, the first cyclone device 230 is connected to the bottom of the lid member 250.

In the present embodiment, although the first cyclone device 230 is connected to the cap member 250, the present invention is not limited to this embodiment. For example, the first cyclone device 230 may be integral with the cap member 250.

In addition, a channel 232 for guiding the pollutant particles is formed in the first cyclone device 230 for efficiently discharging the pollutant particles into the first dust collecting compartment 214.

At the same time, the channel 232 for guiding the polluting particles sucks air in a tangential direction and directs it down.

Therefore, an inlet 233 of the channel 232 for guiding the polluting particles is formed on the side surface of the first cyclone device 230, and an outlet 234 of the channel 232 for guiding the polluting particles is formed at the bottom of the first cyclone device 230.

Meanwhile, the lid member 250 is detachably connected to the upper part of the dust collecting case 210. That is, the lid member 250 opens and closes the first and second dust collecting compartments 214 and 216 at the same time.

Therefore, when the user disconnects the lid member 250 to which the first cyclone device 230 is connected, in order to discharge the contaminants collected in the first and second dust collecting compartments 214 and 216, the upper part of the dust collecting case 210 is opened. The user then turns the dust collecting case 210 to discharge of polluting particles.

In this case, in order to empty the dust collecting case 210, the user relates the dust collecting case 210 to a waste basket or to the street in order to prevent re-contamination of the interior of the room and empties the dust collecting case 210.

In addition, an air outlet 251 is formed in the lower part of the lid member 250 through which air is emitted from which the contaminants are separated in the first cyclone device 230. The upper part of the filter element 260 with a plurality of openings 262 is connected to the outer circumference of the air outlet 251.

Accordingly, the air from which the contaminants are first separated in the first cyclone device 230 passes into the air outlet 251 through the filter element 260.

In addition, a channel 253 for directing air into the first air outlet 252 is formed in the lid member 250. That is, the channel 253 functions as a channel for connecting the air outlet 251 to the first air outlet 252.

In addition, the lid member 250 is provided with an aperture 254 for sucking in particulate matter through which the contaminants separated in the second cyclone device 300 pass, and an aperture 257 for discharging particulate matter through which air passing into the lid member 250 passes into the second dust collector branch 216.

A hole 254 for sucking contaminants is formed at the top of the lid member 250. As shown in FIG. 3, the contaminant suction port 254 consists of two openings that are symmetrically located on both sides of the first air outlet 252. A contaminant discharge port 257 is formed at the bottom of the lid member 250.

As described above, when a hole 254 for absorbing contaminants is formed in the upper part of the lid member 250, and a hole 257 for discharging contaminants is formed at the bottom of the element 250 of the lid, then between the hole 254 for drawing in contaminants and the hole 257 for discharging particles space.

Therefore, the contaminant suction port 254 through which the contaminants are sucked is preferably designed to efficiently transport the contaminants into the contaminant discharge port 257. To accomplish this, a rib 258 is provided for guiding the pollutants to efficiently move the pollutants sucked into the pollutant suction port 254 to the second dust collecting compartment 216 through the pollutant discharge port 257.

An edge 258 for guiding the pollutant particles passes from the hole 254 for suction of the pollutant particles into the hole 257 for the release of pollutant particles. Therefore, the ridge 258 for guiding the contaminant particles comprises a first side corresponding to the hole 254 for sucking the contaminant particles and a second side corresponding to the hole 257 for discharging the contaminant particles.

By means of a rib 258 for guiding the pollutant particles, a channel for pollutant particles is formed on the lid member 250, through which the pollutant particles separated by the second cyclone device 300 pass.

Therefore, the contaminants passing through the contaminant suction port 254 can be efficiently directed to the contaminant discharge port 257, thereby preventing the accumulation of contaminants passing into the contaminant suction port 254 in the lid member 250.

As described above, in accordance with the distinguishing feature of the present embodiment, the first cyclone device 230 is installed in the dust collecting device 200, and the second cyclone device 300 is installed in the main body 100.

However, the cyclone device may further comprise a third cyclone device. In this case, the third cyclone device is also mounted in the main body 100.

Alternatively, the first and second cyclone devices may be installed in the dust collector 200, while the third cyclone device is installed in the main body 100.

That is, in accordance with the present invention, among the plurality of cyclone devices, one or more cyclone devices are installed in the dust collecting device 200, and the rest are installed in the main body.

Alternatively, the cyclone device provided in the dust collector 200 may be called a dust collection cyclone, and the cyclone device provided in the main body 100 may be called the cyclone of the main body. One or more dust collecting cyclones and one or more cyclones of the main body may be installed.

6 is a perspective view illustrating a state in which the guide cover is disconnected from the vacuum cleaner.

As shown in FIG. 6, a second cyclone device 300 is mounted on top of the main body 100.

A connecting channel 114 is provided at the bottom of the second cyclone device 300 for directing air leaving the dust collector 200 to the second cyclone device 300.

A second suction port 302 is formed on the second cyclone device 300 for sucking air passing through the connecting channel 114 into the second cyclone device 300.

Moreover, for directing the air in the tangent direction of the second cyclone device 300, a guide rib 304 is formed near the second suction port 302 in the tangent direction of the second cyclone device 300.

In addition, the main body 100 is provided with an air inlet (118 in FIG. 7) through which air passes from which contaminants are removed in the second cyclone device 300.

Here, the air intake port 118 and the second cyclone device 300 communicate with each other when the guide cover 160 is mounted on the second cyclone device 300 and the main body 100.

Therefore, the guide cover 160 closes the second cyclone device 300 and at the same time forms an air outlet (116 in FIG. 7) through which the air leaving the second cyclone device 300 passes into the air intake 118.

Below will be described the operation of this vacuum cleaner 10.

7 is a sectional view of a vacuum cleaner.

As shown in FIG. 7, when electric power is supplied to the vacuum motor 150 of the vacuum cleaner 10, the vacuum motor 150 creates a suction force, and thus, air containing contaminants is sucked into the suction nozzle by the created suction force.

Air sucked in through the suction nozzle is guided to the main body 100 through the suction portion 110 of the main body and then sent to the dust collector 200 through the connecting channel 112.

That is, air containing pollutants is sucked in the tangent direction of the first cyclone device 230 through the first suction port 212 of the dust collecting case 210. Then, the intake air rotates downward around the inner circumference of the first cyclone device 230, whereby the air and the pollutants are separated from each other under the action of centrifugal force.

The air from which the pollutants are separated passes through the filter element 260, where the pollutants from the air are further filtered. Then, air leaves the dust collector 200 through the first air outlet 252 and the air outlet 251.

The separated pollutants then pass into the channel 232 to guide the pollutants in a tangential direction while rotating along the inner circumference of the first cyclone device 230.

Then, the pollutants passing into the channel 232 for directing the pollutants change their direction of movement in the channel 232 for directing the pollutants and move downward through the outlet 234 along the outer circumference of the first cyclone device 230 and are collected in the first dust-collecting compartment 214.

Meanwhile, the air passing through the first air outlet 252 passes into the main body 100. Then, the air passes into the second cyclone device 300 through the connecting channel 114.

Then, the air is directed to the inner wall of the second cyclone device 300 in a tangential direction through the second suction hole 310 formed at the end of the connecting channel 114 and, thus, polluting particles contained in the air are further separated.

The air then passes into the air outlet 118 formed in the main body 100 and leaves the main body 100 through a motor pre-filter 152, a vacuum motor 150 and an air outlet 120 of the main body.

Then, the separated pollutants pass into the dust collecting device 200 through the hole 254 for sucking the polluting particles and are collected in the second dust collecting compartment 216.

In addition, to empty the dust collecting case 210, the user disconnects the dust collecting device 200 from the main body 100.

The user then disconnects the lid member 250, to which the first cyclone device 230 is connected, from the dust collector 200. To discharge the polluting particles, the dust collector body 210 is turned over.

FIG. 8 is a cross-sectional view of a dust collector in accordance with another embodiment of the present invention, and FIG. 9 is a perspective view of a vacuum cleaner in accordance with another embodiment of the present invention.

The vacuum cleaner of this embodiment is substantially similar to the vacuum cleaner of the previous embodiment shown in FIGS. 1-7, except that the second dust collecting compartment is separated from the dust collecting device. Therefore, a different part will be described below.

As shown in FIGS. 8 and 9, the dust collecting device 400 of this embodiment comprises a dust collecting housing 410 accommodating a first dust collecting compartment 414, a first cyclone device 430 selectively mounted in the dust collecting housing 410 and separating contaminants contained in the air, and a lid member 450 for selectively opening and closing the upper part of the dust collecting case 410.

A second cyclone device 300 for further separating pollutants from the air passing through the first cyclone device 430, and a dust collecting container forming a second dust collecting compartment 510 for collecting polluting particles separated in the second cyclone device 300 are provided in the main body 100.

That is, the contaminants separated by the first and second cyclone devices 430 and 300 are collected in a separate compartment.

Moreover, since the first cyclone device 430 separates relatively large contaminants, while the second cyclone device 300 separates fine particulate contaminants, most of the contaminants collect in the first dust collecting compartment 414. That is, the first dust collecting compartment 414 is quite quickly filled with contaminants . Therefore, the first dust collecting compartment 414 needs to be emptied more often.

Therefore, the dust collecting case 410 comprising the first dust collecting compartment 414 is disconnected from the dust collecting container 500 comprising the second dust collecting compartment 510. As a result, only the dust collecting housing 410 can be disconnected from the main housing 100 to discharge the contaminants collected in the first dust collecting compartment 414.

In addition, since the first dust collecting compartment 414 is formed in the dust collecting housing 410, the structure of the dust collecting housing 410 is simplified and facilitated. Therefore, the user can easily handle the dust collecting case 410.

That is, the dust collecting container 500 is detachably mounted on the main body 100, so that it can easily be emptied after disconnecting from the main body 100.

In addition, the dust collecting container 500 is connected to the main body 100 and then the dust collecting device 400 is connected to the main body. Therefore, one surface of the dust collecting container may be formed to fit the shape of the dust collecting housing 410.

Those skilled in the art will understand that various modifications and changes to the present invention are possible. Thus, it is intended that the present invention include such modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
