Description

Water Filter Device

The present invention relates to a water filter device, and more particularly, to an apparatus for removing foreign matter from air by using water as a foreign matter filtering means.

An apparatus (purifier, cleaner, dust collector, etc.) for removing foreign matter from air containing foreign matter such as dust and the like has filtering means operative to selectively remove foreign matter from the air.

Conventionally, a porous filter medium has been used as a foreign material filtering means, but recently, a method of using water as a foreign material filtering means has been devised and used. In the present specification, a water filter device is used to remove foreign matter from the air by using water as a foreign material filtering means.

The pressure water injected into the injection cylinder 131 is recovered by the pressure water pump 141.

However, according to the conventional water filter device, there is a problem in that the structure is complicated because the pressure water supply unit 140 must be provided in order to inject the water for filtering toward the air containing the foreign matter passing through the interior of the injection barrel 131.

And the foreign matter-containing air has a problem that the foreign matter removal efficiency is low because the foreign matter is removed by contacting the filtering water only while passing through the inside of the injection barrel (131).

In addition, the foreign matter-containing air has a problem that the foreign matter removal efficiency is low because the foreign matter is removed in contact with the water for injection of the filtering type.

For convenience of explanation, it is assumed that water for filtering the bottom surface of the tank body 11 is stored.

First, when the operating voltage is applied to the exhaust motor 22, the exhaust fan 23 is rotated, and thus a negative pressure lower than atmospheric pressure is formed in the internal space of the water tank 10.

When a negative pressure is formed in the internal space of the water tank 10, the air containing foreign matter (hereinafter referred to as "air containing foreign matter") is the suction head 26, the suction pipe 25, the suction hole 11a, the water tank. Through the inner tube 21 and the disturbance auxiliary pipe 36 is introduced into the filtering water.

The tapered pipe portion 36b is shaken while the foreign matter-containing air passes through the disturbance auxiliary pipe 36.

The water around the end of the tapered pipe portion 36b is disturbed by the shaking of the tapered pipe portion 36b, thereby increasing the amount of foreign matter removal.

While foreign matter-containing air moves in the filtering water, foreign matter on the line (hair, etc.) is trapped in the filter bar 35.

On the other hand, when a large water flow passes through the scattering field grooves 32a, a large disturbance occurs, thereby increasing the amount of debris removed by the disturbing skirt portion 32.

The foreign matter removal air guided to the upper side of the space separator plate 31 is discharged to the outside through the discharge hole 12a and the discharge guide hole 51a.

When a large amount of water inadvertently flows into the upper region of the space separating plate 31, the buoy 53 is raised to close the discharge hole 12a, thereby stopping the water filtering operation.
