Brush for cleaning water

Utility 20-0317941 rotary mop cleaner

The present invention relates to a water bath vacuum cleaner using water and a rotary brush type for water cleaning.

1 is a general wet vacuum cleaner, the dust trapped by the suction device (10c) enters the water tank suction port (1c) in the main body through the water (4c) is collected in the water. However, air entering the water generates air bubbles containing fine dust by buoyancy, causing water droplets to float out of the water. At this time, the dust inside the water droplets is discharged to the outside of the cleaner. In order to improve this dust emission problem, a wet vacuum cleaner requires a separate separator 6c for cleaning fine dust. Most conventional vacuum cleaners suck in dirt by the vacuum inside the main body by the rotation of the impeller linked to the main body power. This suction method is not effective for removing dirt in places where roughness such as carpet or fiber is severe. In addition, the inconvenience of having to clean the mop in double when inhaling wet dirt or water.

Fig. 2 shows the center of both sides of the side with the brush attached to the power shaft 2d using the rotational force of the motor 1d attached to the suction device and the cylindrical drum 6d linked with the gear or belt 3d as the shaft 8d. Rotating. In this type of suction device, the suction force is rapidly reduced when dirt is exposed out of the suction device, and when the floor surface and the lower surface of the inlet opening are opened during cleaning, on the contrary, when the lower part of the suction device is in close contact with the floor, the suction cleaner is rolled into the suction cleaner inlet. Cause problems.

In a typical vacuum cleaner, a rotating plate is mounted on the bottom surface of the suction device, the rotating plate is rotated using suction air, and a mop is attached to the rotating plate to wipe the bottom with a rotating mop, and it is also known to suck dust. However, in the case of a suction device of a known mop-mounted vacuum cleaner, dust is retained after cleaning because the dust of the mop is dragged around the floor surface for cleaning. In addition, in the case of the brush for cleaning water of the Patent Publication No. 10-2005-0091480, the frictional force between the bottom surface and the suction device is generated according to the suction method of pushing the wiper to the lower portion of the square plane. In addition, when the space between the bottom surface and the lower surface of the suction device opens, the suction force drops rapidly, which makes it difficult to remove wet dirt. A large bucket for supplying water to the suction device is arranged in the expansion pipe, so that the center of gravity is excessively leaned toward the user at the time of cleaning, a lot of force is consumed. In addition, since the water transfer of the water tank supplied to the suction device is stored in the storage hole inside the suction device located under the holder with the opening and closing device at the bottom of the water tank by gravity, the water remains in the storage hole even after the cleaning is finished. The problem is that water flows out to the floor.

SUMMARY OF THE INVENTION The present invention provides a vacuum cleaner and an improved suction device which simultaneously enable a vacuum cleaning function for sucking dust and dirt, such as a floor or a carpet, and water cleaning.

The rotating body has a brush 18 and a squeeze 22 detachable groove 16. The groove 16 for brush detachment of the rotating body is disposed diagonally from the center of the disc to the outside. The rotating disc has a horizontal structure parallel to the bottom of the case, there is a projection between the case and the lower disc of the rotating body to prevent the inflow of air. The protruding wall 17 toward the bottom of the rotating body blocks the dirt to be thrown out by centrifugal force by securing the safety and rotating the brush 18, and is not lower than the lower surface which is in contact with the bottom surface of the suction device case. Length. The detachable brush fitting device 16 for mounting a brush or squeeze does not come down above the protruding wall 17 to secure low noise and stability, and attaches it to a groove in the lower disc.

10 and 11 is a schematic diagram illustrating a water tank vacuum cleaner according to the present invention.

The water tank vacuum cleaner of the present invention is an inlet 101 for sucking dirt, which is an upper structure, an outlet 102 for discharging clean air to the outside after cleaning the dust, and a motor for sucking dust by making a vacuum inside the cleaner. And an impeller 100, a centrifugal force dust collector 112 for improving the binding force of dust and water, a water tank and a body cyclone inner structure 114 for separating air from contaminated water collected in water, and combining the water tank and the body. It is divided into a structure including a locking device 108, and a structure including a water tank 109, a wheel 110 containing water collecting dust and dirt, and discharge air pressure for supplying water to a suction device for cleaning water. The control device 105, the bucket 103 is composed of removable structures.

The suction port 101 is a dust suction port captured into the water tank 109. Inlet 101 is connected to the suction hose (29). The correct embodiment of the present invention is to position the water supply straw 104 in the upper portion of the annular bucket 103 to clean the water disposed below the main body suction port 101, the water supply hose 28 to be supplied to the suction device And the dirt suction hose 29 are connected side by side.

In FIG. 12, the outlet 102 is a place where clean air washed in the tank is discharged, and can connect an outlet air pressure control device 105 for supplying water to the spray device 23 for cleaning the vacuum cleaner. It has a cylindrical structure. Since closing the discharge port 102 for recycling the vacuum cleaner exhaust air may cause an overload of the motor due to a decrease in suction power, an automatic pressure regulator is required.

The correct use example is that when the pressure is applied by the air entering the water tank 103 by the exhaust air, the water is ejected to the straw 104 located on the inlet side. When the water pressure inside the water tank is saturated, the check valve 105c located above the water surface inside the water tank 103 is closed, and the pressure plate 105d is raised by the spring contraction action of the air pressure regulating device 105, so that the air discharge passage 105g. Will be opened. In addition, it is possible to adjust the spray intensity is proportional to the amount of exhaust air by the adjusting screw 105f of the adjusting device. Opening and closing operation of the water spray button 26 provided in the handle pipe 27 can be supplied to the suction device and shut off.

The check valve stopper 105a of the bucket of FIGS. 13 and 14 functions to prevent the back flow inside the bucket of the check valve 105c connected to the hard straw 105b passing through the stopper. The check valve is a round end hose with a hollow center that closes when the internal pressure of the water tank rises. It is a soft rubber material that is opened when the air enters the water tank in the form of a cut portion 105e and closes when the air pressure is saturated.

Fig. 15 is a centrifugal force dust collector of a water tank vacuum cleaner of the present invention. The dust and dirt trapped by the suction device pass through the vacuum cleaner main body suction port 101 and flow into the main tank inner suction passage 113. Air trapped inside a typical wet vacuum cleaner tank generally enters the water, producing buoyant air bubbles. The present invention provides a centrifugal force dust collector 112 for improving the fine dust dust remaining in these air bubbles.

It is a device for reliably collecting the residual dust which failed to collect by suctioning wet dirt by spraying water from the said suction device.

Correct usage example, the air containing the dust trapped inside the tank is moved to the centrifugal force dust collector located in the lower part of the main body, the lower side of the suction passage 113 is rotated along the circular passage inside the dust collector by the open structure To form airflow. The high velocity of airflow and the water flowing in from the bottom of the tank produce droplet whirlwinds. At this time, the surface area of the water and dust is widened to improve the dust collection efficiency. The structure of the centrifugal force dust collector is a circular structure in which the lower part is in close contact with the bottom of the tank and the side and the upper part are closed. The centrifugal force dust collecting device has an inlet for introducing air to the upper portion in a circular ring shape with a hollow center, and an outlet 112a for rotating the water column into the water tank is opened to the side and the water column along the wall inside the water tank. It rotates. The water column rotating along the inner wall of the tank forms a cyclone according to the inner structure of the tank to separate water and air. Small droplets separated from the water column rotating inside the tank rises along the vacuum intake airflow, passes through the narrow passageway 114, and the speed of the airflow becomes faster. Airflow from narrow passageways decreases in velocity in large passageways, forming secondary cyclones. At this time, droplets and air are separated. Cleanly cleaned air passes through the impeller under the motor and exits the outlet.

Although the present invention has been described in detail with reference to the drawings, the present invention is not limited thereto.

It describes the process of using a water cleaning rotary brush tank vacuum cleaner having such a configuration.

Opening the water tank lock 108 to fill water in the water tank 109 and lifting the body up (FIG. 11) separates the upper body and the lower water tank. The tank must be filled with water to use the vacuum cleaner. This is because the water tank having the suction means is a space for collecting and storing dust and dirt with a function similar to that of a filter and a dust bucket of a general vacuum cleaner. When the tank is filled with water, it locks after combining the tank body coupling unit and the tank.

The water in the bucket is filled to supply water to the suction device for cleaning. Hold the two water bottle caps at the bottom of the vacuum cleaner's inlet and outlet, and lift them up to remove the circular ring of water from the body. The bucket does not need to be filled with water when cleaning the dust only for cleaning the water. The water filling of the water tank opens and checks the check valve stopper 105a or the straw stopper 104a. If you need to clean the inside of the bucket, simply open the two caps. After filling the water tank, the check valve stopper 105a is mounted below the outlet 102 and the straw 104a is positioned below the inlet 101.

After filling the water tank and closing the outlet and the check valve stopper 105a by closing the outlet 102 and the outlet air pressure regulator 105 is connected. Exhaust air pressure control device 105 can be installed anywhere, such as pipe 25 or hose 28, outlet 102, and must be connected to the check valve plug and the device for utilizing the air from the outlet.

The suction hose 28 is connected to the suction port 101, and the suction device is connected to the handle pipe 27 and the pipe or the elastic pipe according to the user's preference. In order to clean the water is connected to the water spray device 23 and the water supply hose 29, the handle pipe 27, the straw 104a in the suction device.

The rotary brush suction device of the present invention can be used for various purposes, and can easily replace the brush 18 and the squeeze 22 during carpet, bed dry vacuum and floor water cleaning. In the groove of the detachable brush fitting device 16 in the lower body disc 17 of the suction device case 14, the brush is replaced with a brush or a squeeze according to the user's use. Dry dust suction and wet dirt can be easily removed, and both can be attached at the same time to use both dry and wet. When only the brush is attached to the rotating body, it effectively absorbs the deep dust of the fibrous fibers such as duvets, carpets, and sofas, and when only the squeeze is attached, it is suitable for removing wet soil from the floor of the floor. The suction device has a brush structure in which the center of the lower disc is concave, so that dirt can be sucked effectively even in a curved or uneven place. The nut 20 for fixing the rotating body spirally prevents the duvet and the like from being sucked into the suction device.

As described above, the brush sweeps the dirt of the place to be cleaned by the rotary brush suction device of the present invention, wipes it with a squeeze, and cleans the process of strongly suctioning by the blade at high speed. In addition, the suction device facilitates the suctioning of dry dust or wet dirt, such as duvets, beds and carpets, as well as floor vacuuming. In addition, the suction power of two powerful motors allows the suction to remove uneven floors, tiles and rough floor soil. Easy removal of the brush and squeeze allows you to switch between wet and dry cleaning. In addition, by spraying from the suction device to collect the dust in the water, the centrifugal force dust collector improves the dust collection efficiency of the vacuum cleaner. The exhaust air can be recycled for cleaning and suction cleaning by spraying water or air with a sprayer.
