Description

The present invention relates to a vacuum cleaner and, more specifically, a cyclone dust extractor for a vacuum cleaner for separating and collecting dust and pollutants from air containing pollutants by centrifugal force that is generated by the formation of an air vortex.

The well-known cyclone dust extractor for a vacuum cleaner comprises a cyclone, a dust tank and a grate. The cyclone includes an air inlet pipe and an air exhaust pipe. The air inlet pipe is connected to the air inlet on one side of the cyclone. The air inlet pipe is connected to the air inlet port in communication with the suction port of the suction brush when the cyclone dust collecting device is installed in the vacuum cleaner body. An air outlet pipe is connected to an air outlet at the top of the cyclone. The exhaust pipe for air is connected to the exhaust channel for air in communication with the chamber of the electric motor of the suction brush when the cyclone dust extraction device is installed in the housing of the vacuum cleaner. Air containing contaminants is drawn in by the suction brush into the cyclone in a tangential direction through the air inlet of the vacuum cleaner body and the air inlet tube. The drawn-in air forms a vortex air flow in the cyclone, and thus, dust and pollutants are separated from the air containing the pollutants by the centrifugal force of the vortex air flow, whereby clean air is released through the exhaust duct for the air of the vacuum cleaner body and the motor chamber.

The dust tank is removably connected to the base of the cyclone and receives dust and contaminants separated from the air by the centrifugal force of the swirling air flow in the cyclone.

The grill is located at the opening of the exhaust pipe for air inside the cyclone to prevent the passage of dust and pollutants separated from the vortex air stream through the exhaust pipe for air. The grill includes a grill housing and a plurality of air channels located on the outer periphery of the grill housing, which allows air to flow into the air exhaust pipe.

A conventional cyclone dust extraction device, as described above, is mounted in the vacuum cleaner body such that the air inlet pipe and the cyclone air exhaust pipe are connected respectively to the air inlet and the air outlet for the vacuum cleaner body.

During operation, the suction force is produced by the suction brush, driven by the motor in the motor chamber. The generated suction force draws air containing contaminants on the surface to be cleaned into the cyclone through the suction brush, the air inlet and the air inlet. The drawn-in air is conducted through the air inlet pipe along the inner periphery of the cyclone in an oblique direction to form a vortex air flow. Dust and pollutants in the air are separated by centrifugal force produced by the swirling air stream and collected in a dust tank. Clean air is vented out through the air ducts, an air exhaust pipe, an air exhaust channel and an electric motor chamber.

However, a conventional cyclone dust extraction device, as described above, has the problem of reducing the cleaning ability. Similar cyclone dust extraction devices are not able to maintain a satisfactory amount of dust and allow dust and pollutants to escape with air discharged through the air channel in the grill.

A cyclone dust extraction device for a vacuum cleaner is known, comprising a cyclone having an air inlet and an air outlet and adapted to form a swirling air stream from air containing pollutants drawn through the inlet, a dust tank detachably attached to the cyclone and adapted to the intake of dust and pollutants separated from the air through the centrifugal force of the vortex air flow in the cyclone, a lattice located okol an air outlet inside the cyclone to prevent the passage of dust and contaminants separated from the air through the air outlet and a support means for rotating the grate, designed to support the grate with the possibility of its rotation by the vortex air flow in the cyclone (see published application Germany 10035253 from 08/02/2001).

This device also does not provide effective air purification.

The technical result of the present invention is the creation of a cyclone dust extraction device for a vacuum cleaner, providing maximum separation of clean air from polluted air.

The specified technical result is achieved in that the cyclone dust-removing device for a vacuum cleaner comprises a cyclone having a cylindrical main body having a side surface in which an air inlet is made, and an upper surface in which an air outlet is made, and adapted to form a vortex air a stream of air containing contaminants drawn through the inlet, a dust tank detachably attached to the cyclone and adapted for receiving dust and pollutants separated from air by the centrifugal force of the vortex airflow in the cyclone, a grill located near the air outlet in the cyclone to prevent the passage of dust and pollutants separated from air through the air outlet and lattice rotation means for supporting the lattice with the possibility of its rotation by means of a vortex air flow in a cyclone and containing a supporting element located in the center ntr the air outlet of the cylindrical main body with a plurality of ribs protruding from the inner surface of the air outlet, and a rotating element having a first end rotatably supported by introducing a bearing, and a second end passing through the grate and attached to the bottom of the grate .

The cyclone may include a lid removably attached to the upper surface of the cylindrical main body, an air inlet pipe adapted to be connected to the air inlet channel of the vacuum cleaner main body, an air outlet pipe adapted to connect to the air outlet channel of the vacuum cleaner body and located around center of the cover.

The cylindrical main body and the cover can be removably connected to each other via spiral connecting mechanisms formed on the respective surfaces for connection.

The grill may comprise a grill housing and a plurality of air channels located on the outer periphery of the grill housing at a predetermined angle of inclination to form an air passage to the air outlet.

The grill may comprise a grill housing, a plurality of air channels located in the outer periphery of the grill housing at a predetermined angle to form an air passage to the air outlet, and an element for blocking contaminants located at the bottom of the grill housing.

A fine filter assembly may be located between the upper surface of the cylindrical main body and the lid to filter out fine dust.

The fine filter assembly may comprise a fine filter and a filter frame having a lower mesh structure for receiving and maintaining the fine filter.

The upper surface of the cylindrical main body may slope downward from the radially outer periphery towards the central part.

Additional advantages, objects and features of the invention will be formulated in part in the following description, and in part will become apparent to those skilled in the art after further consideration, or may be studied based on the practical application of the invention.

The invention will be described in detail with reference to the following drawings, which depict the following:

FIG. 2 is a cross-sectional view showing the cyclone dust collecting device shown in FIG. 1 after assembly;

FIG. 3 is an exploded perspective view of a cyclone dust collecting device shown in FIG. 1 prior to being installed in a vacuum cleaner; FIG.

figure 4 is a top view in cross section along line 6-6 of the cyclone dust extraction device shown in figure 1;

figure 5 is an enlarged view of the air channel of the cyclone dedusting device shown in figure 1.

As shown in FIGS. 1 and 2, the cyclone dust extractor for a vacuum cleaner in accordance with an embodiment of the invention comprises a cyclone 50, a dust tank 60, a grill 70, and a grill rotation carrier 80.

The cyclone 50 includes a cylindrical main body 51 and a cover 52 detachably connected to the cylindrical main body 51. The cylindrical main body 51 includes a side surface 51a and an upper surface 51b. An air inlet is formed on one side of the side surface 51a, and an air outlet is formed approximately in the center of the upper surface 51b. The air inlet pipe 53 is connected to the air inlet, which is also connected to the air inlet 210 (FIG. 3) of the main body 200 of the vacuum cleaner. An air outlet pipe 54 is connected to an air outlet approximately in the center of the cover 52, which is also connected to an air outlet 220 (FIG. 3) of the main body 200 of the vacuum cleaner.

During operation, air containing contaminants is drawn in by the suction brush 300 (FIG. 3) into the cyclone 50 in a tangential direction through the air inlet 210 and the air inlet tube 53. In this process, a vortex airflow is generated in the cyclone 50, and the dust and pollutants included in the vortex air are separated from the air by the centrifugal force of the vortex airflow and, thus, through the exhaust pipe 54 for air, the exhaust channel 220 for air and the camera 310 of the electric motor (FIG. 3), clean air is discharged to the outside.

The dust tank 60 is detachably connected to the base of the cyclone 50 and receives dust and pollutants separated from the air by the swirling air flow in the cyclone 50. The dust tank 60 may include a handle to allow easy handling. When the dust tank 60 is full, it can be separated from the cyclone 50 for release.

The grill 70 is located near the air outlet in the cyclone 50 to separate dust and contaminants separated from the air by the vortex stream and to prevent them from passing through the air outlet. The grill 70 includes a grill housing 31 and a plurality of air channels 72 located in the outer periphery of the grill housing 71, which form air passages to the air outlet.

In some embodiments, the lattice rotation carrier 80 includes a carrier 81 and a rotating member 82. The carrier 81 is located in the center of the air outlet of the cylindrical main body 51 and is supported by a plurality of ribs 81a protruding from the inner surface of the air outlet. The rotary member 82 has one end rotatably supported by introducing a bearing. The other end passes through the grating 70 and is attached to the grating 70 at the bottom of the grating 70 by a screw 84. Thus, the grating 70 rotates with the rotating member 82 relative to the supporting member 81 by the swirling air flow generated in the cyclone 50. The rotation of the grating 70 helps prevent leakage dust and pollutants through the air passage of the grill 70.

In a cyclone dust extraction device according to the invention, the grill 70 may include a grill housing 71, a plurality of air channels 72 arranged at a predetermined angle to form an air passage to the air outlet, and a contaminant blocking element 73 located at the bottom of the grill housing 71 .

Figures 4 and 5 show in detail the preferred angle of inclination and its relationship with the vortex air flow. Contaminant-containing air 302 is drawn in through the tangent direction through the air inlet 53. As discussed above, this causes the formation of vortex air flow 304 inside the cylindrical main body 51. In the embodiment shown in FIG. 4, the vortex air flow 304 rotates inside the cylindrical main body 51 in a clockwise direction.

The air ducts 72 are preferably located on the grill housing 71 so as to minimize the penetration of dust or other contaminants through the grill 70. FIG. 5 shows an enlarged view of two adjacent air ducts 312 and 314. The air duct 314 has a front edge 316 and a rear edge 318. The leading edge 316 is a first edge of the air passage 314 meeting the swirling air stream 304. In other words, the leading edge 316 is upstream of the trailing edge 318. The leading edge 316 is preferably attached to the grill housing 71, and the trailing edge 318 is located radially outwardly and circumferentially downstream of the leading edge 316.

With this arrangement, an inclination angle 310 is formed. The inclination angle 310 is the angle between the local tangent line 308 and the air channel 314. The local tangent line 308 is perpendicular to the beam 306 extending from the geometric center of the grill 70 to the air channel 314. An air channel that has an inclination angle is called inclined. This tilt angle 310 can be adjusted to suit various design goals. For example, if the angle of inclination 310 is reduced, this will increase the ability of the grill 70 to separate pollutants from the air, but also increase the energy required to draw air through the grill 70. If the angle of inclination 310 is increased, the cleaning ability of the grill 70 will decrease, but to draw air through the grill 70 will require less energy. You can select the appropriate tilt angle defined by these various factors that best suits your specific design goals.

The lattice rotation feature and the slanted air channel feature can be used individually or in combination with each other.

As best seen in FIG. 2, the pollutant blocking element 73 has the shape of a truncated cone with an expanded lower part, the diameter of which increases in the downward direction. This shape can cause the pollutants collected in the dust tank 60 that floated in the upward flowing air to change direction with the help of the blocking element 73 of the pollutants and thereby fall into the dust tank 60.

The cyclone dust extractor for a vacuum cleaner in accordance with the invention is further provided with a fine filter assembly 90 inserted between the cylindrical main body 51 and the cover 52 of the cyclone 50 for filtering fine dust that is not removed by the grill 70.

The fine filter assembly 90 includes a fine dust filter 91 such as a sponge or other porous material and a filter frame 92 having a lower mesh structure for receiving and maintaining the fine filter 91. The fine filter assembly 90 filters out fine dust passing through the grill 70 and prevents this fine dust from escaping from the cylindrical main body 51. The upper surface 51b is preferably formed slanted downward from the radially outer periphery toward the center so that the fine dust filtered by the fine filter assembly 90 fell down into the dust tank 60 rather than staying between the upper surface 51b of the cylindrical main body 51 of the cyclone 50 and evil 90 fine filter.

The cyclone dust extractor described above for a vacuum cleaner can be installed in the vacuum cleaner body 200, as shown in FIG. 3, so that the air inlet pipe 53 and the air outlet pipe 54 for the cyclone 50 are connected respectively to the air inlet 210 and the exhaust outlet 220 for air cleaner housing 200.

In operation, a suction force is created near the suction brush 300, driven by a motor (not shown) in the motor chamber 310. The generated suction force draws air containing contaminants on the surface to be cleaned into the cyclone 50 through the suction brush 300, the air inlet 210 and the air inlet 53. The drawn air passes through the air inlet tube 53 along the inner periphery of the cyclone 50 in an oblique direction. This helps to create a vortex airflow, and dust and pollutants in the air are separated by centrifugal force produced by the vortex, and collected in the tank 60 for dust. After that, clean air is discharged outside through the air passage of the grill 70, the exhaust pipe 54 for air, the exhaust channel 220 for air and through the chamber 310 of the electric motor. With this arrangement, dust and contaminants rarely pass through the air passages of the grate 70. However, even if fine dust, which is not separated by the grate 70, is discharged through the air passage of the grate 70, this fine dust is secondly filtered by the fine filter unit 90 (FIG. 2 ), thus improving the amount of dust collection.

In accordance with the invention described above, dust and pollutants are separated from the air by centrifugal force while the grill rotates to prevent dust and pollutants from passing through the grill, so dust and pollutants pass through the grille air passages with difficulty.

Further, even if the fine dust passes through the air passage of the grill, it is secondly filtered by the fine filter assembly, thereby improving the dust collection quality, as well as improving the cleaning ability.

Although the invention has been shown and described in relation to some preferred variants of its implementation, specialists in the art should understand that it is possible to make various modifications of the form and details, without going beyond the essence and scope of the claims defined by the attached claims.

The foregoing embodiments and advantages are merely exemplary and should not be construed as limiting the present invention. The presented idea can be easily applied to other types of devices. The description of the present invention is intended to illustrate and not to limit the scope of the claims. Those skilled in the art will recognize many alternatives, modifications, and modifications.
