BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an environment purifying apparatus that sucks foreign substances in the environment together with air and removes them from the air.

[0002]

2. Description of the Related Art As a conventional environmental purification device of this type,
An ordinary vacuum cleaner equipped with a mesh filter and a special vacuum cleaner which allows air containing sucked foreign matter to pass through the water are known. However, with an ordinary vacuum cleaner, dust of 0.3 mm or less passes through the mesh of the filter, and dust of about 0.001 mm (hereinafter referred to as "micro dust") and smoke are once sucked and discharged into the air and then scattered. I had done it. For this reason, it is said that a person inhales micro dust and causes diseases such as respiratory tract diseases, asthma, atopy, and allergies. If the mesh of the filter is reduced to remove even micro dust and smoke particles, the load on the motor during suction will become excessive and the suction force will decrease. There was a problem that the electricity cost increased as the whole machine became large.

Even in a special vacuum cleaner which allows air containing sucked foreign matter to pass through the water, the foreign matter is exhausted before it sufficiently contacts the water because the air is passed through the water. There is a problem that only about 40% can be removed.

A plurality of disk-shaped stirring members, each of which has its center located on a common axis extending in the horizontal posture, is separated from each other in the axial direction in the horizontal direction, and has a large number of through holes formed therein by the rotation driving means. While rotating around the axis, the air that has passed through the lower stirring member is guided to the upper stirring member by an air guide element, so that the air containing the foreign matter sucked by the suction means is stirred in a liquid such as water. Then, the foreign matter is brought into contact with the liquid, wetted with the liquid and settled to remove the foreign matter from the air, and then the air is released. It is sufficient that the axis extends substantially in the vertical direction, and thus the axis may be slightly inclined, and in this case, the stirring member may also extend substantially horizontally.

Therefore, according to the environment purifying apparatus of the present invention,
Foreign matter such as micro dust that has been sucked in with the air can be brought into contact with the liquid sufficiently and settle in the liquid, so that foreign matter such as micro dust does not have to pass through a fine mesh filter that removes the micro dust. Can be removed satisfactorily, and
Micro dust can be sufficiently satisfactorily removed without using a large motor, which increases the size of the device as well as the electric charge, as the suction means.

It is possible to downsize the liquid storage tank by reducing the amount of foreign substances settled in the liquid storage tank with almost no increase in load.

Further, in the apparatus of the present invention, a plurality of the above-mentioned liquid stirring type foreign matter removing means may be connected in series. In this case, the foreign matter in the sucked air may come into contact with the liquid. As a result, the foreign matter can be more completely removed from the sucked air.

On the other hand, in the apparatus of the present invention, a plurality of the in-liquid stirring type foreign matter removing means may be connected in parallel. By doing so, exhaust gas or the like which has a large suction amount per unit time Even if foreign matter is sucked, the plurality of submerged stirring type foreign matter removing means can share it, so that a large amount of foreign matter can be removed well.

Further, in the apparatus of the present invention, the through hole may be smaller in the upper stirring member of the plurality of stirring members of the liquid submersion type foreign matter removing means than in the lower stirring member. By doing so, air is passed from the lower stirring member having a large through hole to the upper stirring member having a small through hole, so that clogging of the through hole of the stirring member by foreign matter in the sucked air is prevented. At the same time, the foreign matter can be brought into good contact with the liquid by passing through the through hole of the stirring member.

Further, in the apparatus of the present invention, the air guiding element may be a cylindrical portion extending downward from the outer peripheral edge portion of the stirring member. Since the contained air can be guided to the inside of the outer peripheral edge of the stirring member and passed therethrough, the sucked air can be effectively prevented from passing through the stirring member and the foreign matter can be more completely removed from the sucked air. can do.

Further, in the apparatus of the present invention, the air guiding element may be a frustoconical cylindrical portion extending upward from the outer peripheral edge portion of the stirring member.

In the environment purifying apparatus of the above embodiment,
In the case of cleaning a large solid dust of about 1 mm or more, the two-way electromagnetic switching valve 3 connects the inlet 3a to the outlet 3b so that the intake air first passes through the filter type filtration unit 5, while mainly When cleaning the liquid spilled on the floor, the two-way electromagnetic switching valve 3 connects the inlet 3a to the other outlet 3c so that the intake air does not pass through the filter type filtration unit 5 and the submerged agitation type filtration unit 9 directly. To pass through.

Thus, the two-way solenoid operated directional control valve 3 has the inlet 3a.
Motor-type suction fan 7
When the suction port 1 is activated and foreign substances such as dust, dust, smoke, and exhaust gas are sucked together with air, the sucked air is sucked into the conduit 2
Further, the two-way solenoid operated directional control valve 3 is passed through as shown by an arrow A in FIG. 1 to enter the filter type filtration section 5, and foreign matter contained in the intake air, for example, a relatively large one of 1 mm or more is filtered. 1 remains inside the double nets 5b and 5c and passes through the nets 5b and 5c as shown by arrow B in FIG.
As shown by the middle arrows C, D, E, and F in order, the water enters the water tank 9a from the inlet at the lower end of the water tank 9a of the submersible agitating filter unit 9 through the conduit 6 and the motor-type suction fan 7.

In the water tank 9a, the respective centers are located on a common axis line O1 extending in the vertical direction, and in a horizontal posture, they are separated from each other in the direction of the axis line O1 and a large number of through holes 9e are formed. The motor 9c and the gear train 9d rotate the plurality of disk-shaped stirring members 9b around the axis O1, and the skirt 9f and the cone 9g.

As shown by the middle arrow K, the water is discharged from the outlet at the upper end of the water storage tank 11a into the atmosphere via the pipe 12.

When the motor-type suction fan 7 operates with the two-way solenoid operated directional control valve 3 communicating the inlet 3a with the outlet 3C, the suction port 1 sucks the liquid spilled on the floor together with the air. As shown by the arrow L in FIG.
Since the water is passed directly through the pipe line 2 and the two-way electromagnetic switching valve 3 to the water storage tank 9a of the submersible stirring type filtration unit 9, the filter type filtration unit 5 does not become a load, and the liquid is efficiently absorbed with a larger suction force. I can inhale well.

By the way, the on-off valves 14, 18, 22
Is opened at least during the operation of the apparatus of this embodiment, whereby the liquid that has entered the filter tank 5a is discharged into the waste liquid receiving tank 16 and stored therein, and also inside the water storage tanks 9a and 11a. The foreign matter that has come into contact with the water and settled is discharged into the sediment receiving tanks 20 and 24, and the water there is stored therein while being pushed out to the upper water storage tanks 9a and 11a. When the waste liquid receiving tank 16 and the sediment receiving tanks 20 and 24 are filled to some extent, the open / close valves 14, 18, 2
2 is closed, the on-off valve 25 provided in each tank is opened, air is introduced into the tank, and the detachable connector 23 is removed to remove the waste liquid receiving tank 16 and the sediment receiving tanks 20 and 24, and the inside. It is possible to dispose of waste liquid and foreign substances.

Therefore, according to the environment purifying apparatus of this embodiment, foreign matter such as micro dust sucked together with air can be sufficiently brought into contact with water and settled in water, so that fine dust for removing micro dust can be obtained. It is possible to remove foreign matter such as micro dust sufficiently well without passing through a mesh filter, which increases the amount of electricity and enlarges the device. Can be removed.

Moreover, according to the environment purifying apparatus of this embodiment, the foreign matters having a size larger than a predetermined size are removed from the sucked air by the nets 5b and 5c, which are provided in front of the submerged stirring type filtration units 9 and 11. Since the filter type filtering section 5 for removing the water is provided, the load of the motor of the motor type suction fan 7 is hardly increased and the amount of foreign matter settled in the water storage tanks 9a, 11a is reduced to reduce the water storage tanks 9a, 11a. It can be miniaturized.

Further, according to the environment purifying apparatus of this embodiment, since the two submerged agitation type filtration units 9 and 11 are connected in series with each other, the chance that the foreign matter in the sucked air comes into contact with water increases. Therefore, the foreign matter can be more completely removed from the sucked air.

Further, according to the environment purifying apparatus of this embodiment, since the plurality of stirring members 9b and 11b have smaller through holes as the upper stirring members, the lower stirring member having a larger through hole is sequentially arranged. Since the air is passed through the upper stirring member having a small through hole, the foreign matter in the sucked air can be prevented from being clogged with the foreign matter in the air, and the foreign matter can be brought into good contact with the liquid.

Further, according to the environment purifying apparatus of this embodiment, as the air guiding element, there are provided skirts 9f and 11c extending downward from the outer peripheral edge portions of the stirring members 9b and 11b, and the skirts 9f and 11c. However, since the air containing the sucked foreign matter is guided inside the outer peripheral edge portions of the stirring members 9b and 11b and passed therethrough, the sucked air can be effectively prevented from passing through the stirring members 9b and 11b, and suction can be performed. Foreign matter can be more completely removed from the formed air.

Further, according to the environment purifying apparatus of this embodiment, the cone-shaped cylindrical cones 9g and 11 extending upward from the outer peripheral edge portions of the agitating members 9b and 11b are used as the air introducing elements.
Since the cones 9g and 11d have d and guide the air containing the sucked foreign matter to the inside from the outer peripheral edge of the upper stirring members 9b and 11b, the sucked air is stirred.
It is possible to effectively prevent the b and 11b from passing through, and to completely remove the foreign matter from the sucked air.

Although the present invention has been described above based on the illustrated example, the present invention is not limited to the above-mentioned example, and for example, the number of submerged agitation-type filtration sections may be increased or decreased as required, and the above-described implementation is also possible. Water tank 11 of submerged agitation type filtration unit 11 in the example
The lower end of a tank containing only water or an empty tank containing no water is connected to the outlet of the upper end of a through a conduit, and the outlet of the upper end of the tank is connected to the conduit. The water tank 11a is opened to the atmosphere through
Like the projection 11e in the inside, a downward sawtooth (W-shaped) projection is provided to allow the water droplets collected at the upper end to fall naturally into the tank without leaving from the outlet to ensure more reliable discharge of water droplets. It may be prevented.
