BRIEF DESCRIPTION OF THE DRAWINGS FIG.
This will be specifically described. Figure 1 is a longitudinal sectional view showing an embodiment of the present invention, hair bottom provided with outlet 6 with opened upper -
Inward of the right side wall of the case 1, from the case ceiling 1e to the back side wall 1
d is suspended, and a washing water storage unit 10 is provided at the lower end of the rear side wall 1d.

The washing water storage unit 10 contains six washing waters therein.
The left side wall 1c is slightly inclined outward. An exhaust port 6 is provided at a position slightly to the right of the ceiling 1e of the case 1 from the center thereof. A front side wall 1a is provided, which descends in a state of being slightly inclined inward from a portion opposite to the rear side wall 1d with respect to the exhaust port 6 of the ceiling 1e.
The front side wall 1a is formed so as to be inclined so as to be located on an extension of the left side wall 1c of the washing water storage portion 10.

The front side wall 1a is separated from the tip of the left side wall 1c of the washing water storage part 10 by a distance approximately equal to the depth of the washing water from the tip of the left side wall 1c. It is bent at an obtuse angle from the position inside, that is, rightward in the drawing to form the upper portion 4a of the intake guide plate , whereby the lower end portion of the front side wall 1a and the cleaning water accommodating portion 10 are formed. It constitutes an inlet 3 at a portion between the tip portion of the left wall 1c. The upper portion of the intake guide plate 4a is further bent at an obtuse angle downward at a steeper slope from a predetermined position.
b. The tip of the suction guide plate lower part 4b is in contact with the surface of the washing water 2 at rest.

The portion extending from the front side wall 1a to the intake guide plate 4 constitutes a partition plate 11 for partitioning the space between the outside air and the inside of the apparatus.

The outside air passing through the intake port 3 is supplied to a washing water storage unit.
Dust included in the outside air is removed by passing between the cleaning water 2 of 10 and the lower end of the lower portion 4b of the suction guide plate. Further, the rising portion rises from the bottom portion 1b of the washing water storage portion 10 and the upper portion extends along the direction of the suction guide plate 4.
Sloping, suitable for the direction of the intake guide plate 4 at the upper edge
Yichun mosquitoes - wing plate 5 which is curved in blanking is provided.

In the apparatus having the above-described structure, the intake guide plate 4 sucks the outside air containing dust from the intake port 3 and efficiently introduces the outside air into the internal space. utilizing, by large amount to generate water droplets in point C of Figure 2
The intake air guide plate 4 and the upper edge
With the wing plate 5 having the curved surface, accompanying water droplets are finally collected on the intake guide plate 4 and a waterfall is formed by utilizing the inclined head of the intake guide plate lower part 4b. The flow is sent from above the outside air that has passed through the point C so as to have an active cleaning action near the water surface.

Therefore, the feature of this device is at the point C, and the section interval of this portion is configured to be the narrowest. That is, when the sucked outside air flows through the case, the maximum pressure loss is generated at the point C, the speed of the suctioned outside air passing through the point C is maximized, and the cleaning water droplets are efficiently generated. .

Therefore, the symbols AB, D-
The interval of E is several times larger than that of the point C. In particular, the outside air intake part reduces resistance,
The inclination between A and B is made relatively gentle.

Meanwhile, water droplets together with the exhaust gas is transmitted to the left side of the wing plate 5, water droplets reaching the tip wing plate
Is released in the curved surface formed on the upper edge 5, it falls into the intake guide plate top 4a, forms a waterfall by falling transmitted the intake guide plate 4, on the exhaust stream passing through the point C The waterfall has been dropped onto this wing plate 5
Drops water drops on the lower part 4b of the suction guide plate by curving the edge
This is one of the major features of the present invention.

The intake guide plate 4b is steeply inclined toward the point C in order to increase the speed at which the waterfall flows. Such a steep slope widens the interval at the point D and slows the flow of exhaust gas at the point D, thereby increasing the mixing time with water droplets and further improving the cleaning effect. Sucking
The outside air sucked from the air vent 3 is sandwiched between the flow of the waterfall that falls from the intake guide plate 4 and the retained water in the water tank, so that the outside air and water efficiently contact and cool the outside air, and at the same time, the outside air is washed. The effect has been improved . The space between the wing plate 5 and the suction guide plate 4 is a fine mist in order to blow up most of the falling waterfall as water droplets in addition to water droplets generated by blowing the outside air at high speed onto the surface of the retained water. Filled with water droplets (splashes) , these mist-like fine water droplets from below
As it comes into contact with the outside air passing
A spiral swirling flow is formed in the space of the portion
It enhances contact with dust. Therefore, the outside air passing during this time comes in contact with the droplets with very high efficiency,
Further, the cleaning effect is enhanced.

FIG. 3 shows the flow of air and the movement of water droplets when this device is operated. When an exhaust fan (not shown) at the end of the exhaust port 6 is driven, the internal space becomes more negative than the outside air. Therefore, outside air is sucked from the intake port 3. The sucked outside air descends along the left side wall of the intake guide plate 4, pushes down the water surface at the lower end of the lower portion 4b of the intake guide plate, and enters the internal space.

At this time, since the air passes through the narrow space between the lower portion 4b of the intake guide plate and the water surface, the flow of air in that portion increases, and water droplets are wound up toward the wing plate 5. The drawn-in outside air collides with the wing plate 5 and rises along the left side wall, so that the water droplet also rises along the flow. When reaching the upper edge of the wing plate 5, the upper edge
Is curved downward, so that the water droplets
fall on a.

As described above, the water droplets fall as waterfalls along the intake guide plate 4 and mix with the outside air sucked from the intake port 3 to absorb dust such as oil. In this way, the drawn-in outside air has a contact area with water droplets as large as possible to remove dust.

At this portion, most of the dust is removed, and the external air taken in is sucked toward the exhaust port 6. By passing through the eliminator 7 , dust and water droplets are almost completely removed. Since the dust is almost removed by water droplets circulating between the wing plate 5 and the suction guide plate 4, the eliminator 7 is hardly contaminated and maintenance becomes very easy. It is formed on the upper edge of the wing plate 5.
Curved surface may be formed by bending
No.

By the way, as can be seen from FIG. 1, by making the cross section of the washing water accommodating portion located at the lower part of the apparatus smaller than the cross section of the upper part of the apparatus, the internal space becomes gradually lower as it goes below the upper part. The width is configured to be narrow. For this reason, the space between the hood 9 and the washing water storage unit 10 is widened. Therefore, if the partition plate 11 is configured to be detachable by the handle, a maintenance space is provided between the hood 9 and the washing water storage portion, and maintenance is facilitated. In addition, with this configuration, the flow of the air flowing through the internal space is improved, and the flow of the outside air to be taken in is smooth, so that the residence time of the outside air is shortened, and the contamination on the inner surface and side walls of the hood is reduced. .

Although not shown, the wing plate 5 has a space between the front side wall and the back side wall, so that the washing water 2 can pass through the space. For this reason, when the exhaust fan operates, the washing water rises in the space on the right side, and a part of the washing water flows out from the drain port 8. For this reason, the cleaning water decreases during operation, and the cleaning water is constantly replenished by a water supply means (not shown), so that the dirty cleaning water is drained and fresh cleaning water is constantly replenished.

FIG. 4 is a perspective view of the apparatus shown in FIG. 1 in which the two apparatuses are integrated and the amount of intake air is increased, and FIG. 5 is a sectional view of the apparatus. As can be seen from the figure, a part of the front side wall 1a is configured to be detachable, and the handle 12 is easily detached by grasping the handle 12 for maintenance.

The drain port 8 is formed by processing the wing plate 5 as shown in FIG.
Is covered in the longitudinal direction of the wing plate 5 to prevent unnecessary drainage. Also, the front side wall 1a
Is formed so as to be positioned on the extension of the left side wall 1c of the washing water storage section 10. However, if it is necessary to reduce the upper space of the apparatus due to the limitation of the installation place, it is not changed. The washing water storage unit 10 becomes small, and the washing water may run short. In such a case, by increasing the cross section of the washing water storage unit 10 within a range that does not significantly impair the maintenance line, that is, by positioning the side wall of the cleaning water storage unit 10 outside the upper side wall of the apparatus, the cleaning water What is necessary is just to increase accommodation capacity.

[0028]

As described above, the present invention is directed to a suction guide plate which is rolled in the direction of the internal space from the lower end of the upper side wall of the intake port and whose leading end is submerged when the outside air is not being sucked. A wing plate that rises from the bottom of the housing portion and has a front end portion curved in the direction of the intake guide plate, so that the flow of the intake air is smooth, and the water droplets wound up by the flow of the intake move along the wing plate. Again falls on the intake guide plate and becomes a fine mist swirling flow,
This swirling flow enhances the contact with the outside air to achieve high dust collection efficiency
Can be maintained to remove dust.
