DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water purifier having a surfactant and a surface active function, in which an agitator is mounted and a filter box is mounted on an air intake of an intake pipe to control various bacteria, especially Legionella spp. The present invention relates to a purification device.

[0002]

2. Description of the Related Art A conventional ejector-type water purifying apparatus includes:
Water is sent to the ejector by a submersible pump, rapidly ejected from a nozzle provided in the ejector, and the load generated around the nozzle is used to inhale air from the air intake at the tip of an intake pipe attached to the ejector, and While mixing with air to dissolve oxygen, a jet of gas-water mixture is discharged into the water tank from the discharge section at the tip of the pipe connected to the ejector,
It prevents dust and insects from entering through the air intake.

[0003] Japanese Patent No. 3112287 (Japanese Patent Laid-Open No. 10-2)
86594) and the water purification device 1 shown in FIG.
The water sent from the submersible pump 2 is sent to the ejector 4 through the large-diameter pipe 3, and the nozzle 1 installed in the ejector 4
From the air inlet 5a at the tip of the suction pipe 5 attached to the ejector 4 by utilizing the negative pressure generated around the nozzle 10, and mixes air and water to dissolve oxygen. Meanwhile, a jet stream of gas-water mixture is discharged into the water tank from the discharge portion 7 at the tip of the pipe 6 connected to the ejector 4 to activate water or hot water in the water tank. The discharge unit 7 has a blow nozzle 8 provided with a large number of small holes 8a at the tip of
And a wrapper tube 9 in which the blowing nozzle 8 is provided. The large-diameter tubular body 3 accommodates a cylindrical body in which tourmaline ore and a void layer are arranged alternately so that they can be taken in and out. A wire mesh is also attached to the air intake 5b to prevent dust and insects from flowing into the air.

[0004]

In the conventional water purifier, a wire mesh is provided at the air intake, but it has only an effect of preventing relatively large dust and insects from entering the air.
Fine dust and germs contained in the air, fog, rain, etc.
Especially, the invasion of Legionella spp. Cannot be prevented. , Has caused a great problem in hygiene.

[0005] It is an object of the present invention to provide an ejector-type water purifying apparatus which is capable of preventing a fine dust and various germs, particularly Legionella spp. From entering, by attaching a filter box to an air intake. .

[0006]

Means for Solving the Problems In an ejector type water purification apparatus, a box having an open front surface is provided with an opening,
A plurality of rows of a plurality of slits or a plurality of small holes are vertically provided in parallel, a lid provided with an eave on the top of each row of each of the slits or small holes is detachably attached, inside the box,
Attach a partition plate with a number of ventilation holes at intervals on the inner surface opposite the opening, between the partition plate and the lid,
A filter box filled with a U.S.A.A. An opening is provided in the wall on which is placed, and it is connected to the air intake of the intake pipe connected to the ejector.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described with reference to the drawings. The above-mentioned conventional ejector-type water purification device 1
In the same manner as described above, a nozzle 10 for rapidly ejecting water sent from the submersible pump 2 is provided inside the ejector 4, and a blowing pipe 5 opening around the nozzle 10 in the ejector 4 is provided. By using the negative pressure generated around the nozzle 10 by ejecting the air, the air is sucked from the blowing tube 5, the air and water are mixed to dissolve the oxygen, and the discharge portion 7 at the tip of the tube 6 connected to the ejector 4. In this configuration, a jet of more water / water mixture is discharged. However, in the conventional water purification device 1, a wire mesh is attached to the tip of the intake pipe 5, but in the device of the present invention, the wire mesh is not attached, and the filter box 11 is attached instead.

In the filter box 11, a partition plate 13 having a large number of through holes is provided at an interval 12 on the inner surface of the intake pipe 5 on the side of the air intake port 5b. A special filter 14 of an air filter of a clean air purity of 100 or higher according to the U.S.A. A lid 16 having a large number of air holes in a plurality of rows arranged in parallel in the front is detachably attached.

As a class 100 filter of the United States Aerospace Agency, there is a HEPA filter (high-efficiency particle air filter (high-efficiency dust-collecting air filter). The class 100 has a particle size of> 0.5. (Μ), cumulative number of particles 100 (particles / ft ³ ), floating amount 0.1 (particles / ft ³ ), sedimentation amount 12,900 (particles / ft ³ )
m ² weeks), and is repellent to most bacteria, especially Legionella spp. As a high-efficiency dust collection filter of class 100 or higher, there is an ULPA filter (ultra low penetration air filter) (ultra low permeation air filter). As the special filter 14, HE
A PA filter, a ULPA filter, or an air filter having a similar cleanness is used.

On each row of the ventilation holes of the lid 16, there are provided eaves 17 which are inclined downward and oblique, like folds of a hundred-leaf box. The eaves 17 are for preventing rain falling down from entering the box 11 through the through holes of the lid 16.

At the front end of the bottom of the box 11, a hole (not shown) is provided for discharging the flow of the water droplets prevented by the filter 15 out of the box 11.

The air that has passed through the special filter 14 of the box 11 collides with the high-speed water discharged from the nozzle 10 in the pipe 6 to generate fine bubbles. Since the tube 6 is bent, the bubbles collide with the wall surface of the tube 6 and are further subdivided, and the water containing the bubbles collides with the inner wall of the nozzle 8, and the collision and the increase in pressure due to the decrease in flow velocity cause the bubble. It is miniaturized and released into the horn tube 9 through the small hole 8a. The air bubbles released into the wrapper tube 9 are further broken by colliding with the inner surface of the wrapper tube 9 and are further miniaturized to promote the dissolution of oxygen in water.

A conventional ejector type water purifying apparatus other than the water purifying apparatus 1 of Japanese Patent No. 312287 also has a box 11 attached to its air intake port.
It is possible to prevent invasion of minute germs, particularly Legionella spp.

[0014]

The water purifying apparatus according to the present invention is a special filter which is an air filter for collecting dust at a clean air purity of 100 or more according to the U.S.A.A. The special filter prevents the invasion and propagation of microbes, especially Legionella spp., Purifies the water, dissolves oxygen into the water, and activates the water.
