Description

[0001] The present invention relates to a vacuum cleaner including a water sprayer into a sponge filter,

The present invention relates to a vacuum cleaner having a spraying device, more particularly, to a vacuum cleaner for collecting large dust first in the air sucked by a vacuum cleaner, and finally adsorbing dust in the air The present invention relates to a vacuum cleaner having a sponge filter for spraying water by applying a Bernoulli principle widely used in an atomizer and wetting a sponge filter at the distal end of the vacuum cleaner to adsorb minute dust.

Generally, a vacuum cleaner sucks air containing dust by using a suction force generated by a suction motor mounted inside the main body, and then filters dust and filters dust inside the main body.

The vacuum cleaner includes a canister type vacuum cleaner in which a main body and a suction nozzle are separated from each other and connected to each other by a pipe and a hose, and an up-right type vacuum cleaner provided with a suction nozzle and a main body. do.

Generally, the structure of the vacuum cleaner includes a suction nozzle, a dust collecting device for collecting and collecting dust and other foreign matter from the air introduced from the suction nozzle, and a fan motor assembly connected to the air discharging part of the dust collecting device to generate a suction force. And a sponge filter connected to the discharging portion of the fan motor assembly for filtering air flowing out to the outside.

However, the air exhausted from the vacuum cleaner has fine dust of a predetermined size or less, and the fine dust is not completely filtered by the sponge filter, but is exhausted as it is.

Accordingly, in order to remove fine dust contained in exhaust air, a multi-filter such as a triple filter or a quadruple filter is used to minimize the amount of fine dust contained in the exhaust air. To this end, in order to remove fine dust, HEPA (High Efficiency Particulate Air Filter) filter.

However, as described above, fine particles such as dust, bacteria, viruses and the like are not collected by a high-performance filter such as a HEPA filter but are discharged again to the outside of the vacuum cleaner.

In addition, the above-mentioned micro dust and other foreign matter may cause respiratory diseases when humans inhale.

In order to solve the above problems, Korean Patent Laid-Open Publication No. 10-2011-0049105 discloses a vacuum cleaner capable of sterilizing exhaust air and adsorbing fine dust by spraying steam or detergent onto a sponge filter.

The vacuum cleaner includes a water tank for containing water, a steam generator for generating water by heating water in the water tank, and a steam generator for supplying steam supplied from the steam generator to the side of the sponge filter And since moisture is absorbed by the sponge filter, moisture can be supplied to all parts of the sponge filter.

Accordingly, it is possible to wet the sponge filter by dewatering water to remove fine dust discharged from the vacuum cleaner. However, as shown in FIG. 1, it is necessary to provide additional complex devices such as a steam generator for heating water, The size of the vacuum cleaner can not be reduced and the structure becomes complicated.

Hereinafter, the present embodiment will be described in detail with reference to the accompanying drawings.

3 is a side sectional view showing a section of a vacuum cleaner according to the present invention.

As shown in the drawings, the vacuum cleaner according to the present invention preferably includes a cyclone dust collecting unit 31 for sucking dust from a portion to be cleaned.

As shown in FIG. 2, the gas introduced into the vacuum cleaner in accordance with the principle of cyclone is sucked while spirally rotating inside the conical cylinder.

The dust contained in the air is separated from the gas at the inner wall of the cylinder by the centrifugal force, flows downward along the wall surface, and is stored in the lower discharge tube.

Since the central portion of the conical cylinder is maintained at a negative pressure, the gas separated from the dust particles ascends to the upper portion and is directed to the middle exhaust hole 35. [

It is preferable that the vacuum cleaner includes a body 10 in which each component of the vacuum cleaner is disposed and forms a surface of the vacuum cleaner and a handle 13 provided at a lower portion of the body 10 and easily gripable by a user Do.

The vacuum pump motor 33 serves as a power source for sucking air into the vacuum cleaner, and the sucked air exits to the intermediate vent hole 35 located at the end of the vacuum pump motor 33.

A portion of the sucked air is concentrated and escaped through the exhaust vane funnel 37 to the nozzle portion 39 and another portion is directed into the open space around the exhaust vest funnel 37 and directed toward the sponge filter 91 do.

The cross sectional area of the exhaust vulture funnel 37 is preferably selected within a range of 3 to 20 times the cross sectional area of the nozzle portion 39.

A water tank 51 for storing water located at an upper portion of the body 10 has a cap 53 for sealing the water inlet 55 provided in the upper part of the water tank 51 to prevent water from leaking to the outside A water inlet 55 which is a passage through which water is introduced and a control valve 71 which can move up and down using the screw portion 73 to adjust the flow rate of water discharged into the water supply hole 57 .

When the water is discharged to the water supply pipe 59 extending along the vertical downward direction of the water supply hole 57 and the vacuum pump motor 33 is operated, water discharged by the flow of the intake air exiting the nozzle unit 39 So that the spongy filter 91 is wetted with the sponge filter 91 and the operation is continuously performed, so that the filtered air is discharged to the final exhaust hole 95.

The principle of the Bernoulli applied to the present invention is that the water contained in the lower part of the water supply pipe 59 is supplied to the nozzle part 39 using the principle that the pressure is lowered at a place where the flow of the fluid is faster and the pressure is higher at the place where the flow of the fluid is slow And is sprayed toward the sponge filter 91. The sponge filter 91 is made of a synthetic resin.

Since the sectional area of the portion of the funnel funnel 37 facing the vacuum pump motor 33 is 3 to 20 times larger than that of the nozzle portion 39 due to the Bernoulli principle, the flow of the fluid is slow, The nozzle section 39 of the exhaust vulture funnel 37 has a small cross-sectional area, so that the flow of the fluid is fast, so that the pressure is low.

Accordingly, since the pressure in the lower part of the water supply pipe 59 is low, the water stored in the water tank 51 can be naturally flowed downward and sprayed toward the sponge filter 91.

Meanwhile, a concrete embodiment of the procedure for operating the vacuum cleaner of the present invention is as follows.

The water supply hole 57 is closed by turning the screw portion 73 of the control valve 71 as much as possible before turning on the vacuum cleaner.

Then, the stopper 53 provided in the water tank 51 is opened, the water is filled into the water tank 51 through the water inlet 55, and the stopper 53 is closed so that the water does not flow out.

Then, when the vacuum cleaner is operated and the control valve 71 is slowly rotated to raise the water supply hole 57, the water stored in the water tank 51 falls down in the gravity direction through the water supply pipe 59.

It is preferable that the outside of the side surface of the rear portion of the intermediate exhaust hole 35 of the vacuum cleaner is made of a transparent material so as to adjust the water supply amount by adjusting the control valve 71 to a proper height of the control valve 71.

The water dropped through the water supply pipe 59 is sprayed toward the sponge filter 91 by the flow of high-speed air passing through the nozzle unit 39 of the exhaust vat funnel 37.

As the vacuum cleaner is operated, most of the dust is collected in the cyclone dust collecting part 31 and air containing fine dust passes through the vacuum pump motor 33 and passes through the intermediate exhaust hole 35 located in the middle of the body 10 And a part thereof flows through the exhaust collection funnel 37 and the rest flows toward the sponge filter 91 through the outside of the exhaust collection funnel 37.

The water particles sprayed on the sponge filter 91 are mixed with the exhausted fine dust and adsorbed on the sponge filter 91 to improve the filtration performance of the water particles impregnated with the sponge filter 91 to the fine dust.

When the operation of the vacuum cleaner for sucking dust is completed, first, the control valve 71 is rotated and lowered to block the water supply hole 57 by blocking the water supply hole 57 and confirming that all the water remaining in the water supply pipe 59 has escaped It is preferable to stop the operation after that.

Meanwhile, the filter case 93 is constructed to be separated from the body 10, and the sponge filter 91 is taken out at regular intervals to be cleaned and reused.

Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art will appreciate that the present invention can be embodied in other specific forms without departing from the spirit or essential characteristics thereof will be.
