Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application] The present invention relates to a filter device for removing dispersed particles and bacteria mixed in air, and particularly to a kitchen, a barn, a beauty salon, a coating booth, It is used in food factories, precision machinery factories, etc., and is attached to a ventilation port or room, or an air conditioner,
It is capable of removing oil, dust, odor, bacteria, etc., and has improved fire resistance, cleaning workability, and maintenance cost.

(Prior Art) As conventional grease filter devices for kitchens, there are known, for example, SAI 57-123614, SAI 57-33926, SAI 57-11435, and SAI 57-184434.

The grease filter device 1 of the above-mentioned Japanese Utility Model Publication No. 57-123614
In FIG. 5, as shown in FIG. 13, it is attached to the inlet 18 of the smoke exhaust passage 17 provided on the kitchen equipment 16, and the fan 19 is provided at the other end of the smoke exhaust passage 17 to The oil smoke generated from the kitchen equipment 16 is guided outdoors.

The filter portion 20 of the grease filter device 15 has a fourteenth
As shown in the figure, a plurality of guide plates 22 having an S-shaped cross section are provided on one of the frame bodies 21a and 21b divided into front and rear, and a vane plate having a V-shaped cross section is provided on the other frame body 21b. 23 are provided alternately on the guide plate 22 so that they can be moved closer to and away from each other, and an eccentric 26 is connected to a connecting rod 25 operated by a temperature-sensitive bending element 24 so that the eccentric 26 can be activated when the temperature rises in the event of a fire.
Is configured to press the guide plate 22 so that the flame does not spread to the smoke exhaust passage 17.

When the grease filter device 15 is operated, the oil smoke sucked from the suction port 27 passes through the gap between the guide plate 22 and the blades 23 and is guided to the smoke exhaust passage 17. At this time, the oil smoke is guided. The plate 22 and the vane 23 collide with each other, and the collision causes the oil to adhere to the plates 22 and 23, whereby the oil is separated.

(Problems to be Solved by the Invention) However, in such a conventional grease filter device, oil is trapped by causing oil-containing air to collide with and adhere to a guide plate or a wing plate. Therefore, the amount of oil adhered becomes huge due to long-term use, and since the guide plate and the wing plate are installed close to the fire of the kitchen, the oil attached to the guide plate and the wing plate is ignited, There was a problem that the risk of fire was great.

Certainly, the above-mentioned conventional grease filter device and the like are fireproof members (temperature-sensitive bending element 24, eccentric element 26, connecting rod 25).
However, since oil adheres to such a fire prevention member, there is a problem that it does not operate even in the event of a fire.

Further, there is a problem that the work of removing the oil adhering to the guide plate and the blade is troublesome, the cleaning workability is poor, and the maintenance cost of the grease filter device is high due to this.

Further, such a grease filter based on collision separation has a drawback in that it is limited to capturing oil or the like, which is a large particle to some extent, and cannot be applied to capturing fine particles such as odor, dust, and bacteria.

The present invention has been made in view of the above-mentioned problems of the prior art, and is excellent in fireproofness and cleanability, and is a versatile filter device capable of capturing oil, odor, dust, bacteria and the like. The purpose is to provide.

[Means for Solving the Problems] (Means for Solving the Problems) The present invention for achieving the above object provides a filter box including an intake port for intake of air mixed with dispersed particles and an exhaust port for exhaust of the air. A filter device comprising a main body and an air discharge means arranged on the discharge port side for sucking air, in which a plate portion for storing separated liquid is formed on a bottom wall of the filter box main body, And a partition plate that shields the discharge port, the lower end edge of the partition plate is provided in the filter box main body so as to be immersed in the separated liquid stored in the dish by a predetermined amount, and the partition plate is provided on the downstream side. A partition plate that forms a space between the partition plate and the partition plate and has a plurality of ventilation holes, the filter so that the lower end edge of the partition plate is immersed deeper in the separation liquid than the lower end edge of the partition plate. Installed on the box body, A filter and wherein the said vent hole for communicating the space of the outlet side is disposed the separator plate so as to face the laterally.

Further, the separating plate may be made of a porous ceramic material.

(Operation) In the filter device according to the present invention, when air is sucked by the air discharging means from the outlet side of the filter device, the air pressure on the outlet side becomes lower than the air pressure on the inlet side, and the filter box Since the water level of the separated liquid stored in the dish portion of the bottom wall of the main body is partitioned by the partition plate, the water level on the outlet side of the partition plate rises, while the water level on the suction port side of the partition plate falls.

Then, when the water level on the suction port side becomes slightly lower than the lower edge of the partition plate, the air containing dispersed particles sucked from the suction port passes through this gap, and the discharge port of the partition plate whose water level has risen. While passing the separated liquid on the side water surface, it floats in the form of bubbles. At this time, the dispersed particles are separated from the air, and the dispersed particles are trapped in the separated liquid.

When the air sucked in through the suction port passes through the lower edge of the partition plate and reaches the space between the partition plate and the separation plate, the water droplets are wound up upward, but the separation plate has its ventilation hole horizontal. Since it is arranged so as to face in the direction, the air flows through the ventilation hole to the outlet side, but the water droplets wound up above do not flow to the downstream side through the ventilation hole due to its inertial force, The separation liquid is prevented from scattering. Furthermore, the air is rectified as it passes through the ventilation holes of the separation plate,
The generation of noise can be prevented.

Also, if the separation plate is made of a porous ceramic material,
The flow of air is further rectified to prevent noise from being generated, and the separated liquid is prevented from scattering downstream from the separation plate.

(Example) Hereinafter, it demonstrates based on the Example of this invention shown in figure.

1 is a perspective view showing a filter device according to an embodiment of the present invention, FIG. 2 (A) is a sectional view taken along line II-II of FIG. 1,
FIG. 2 (B) is an enlarged perspective view of the angle member 12 portion of FIG. 2 (A), and FIG. 3 is a vertical sectional view for explaining the operating state of the present embodiment. The same parts as those of the grease filter device are designated by the same reference numerals.

First, in FIGS. 1 and 2 (A) and (B), an approximately quadrangular pyramidal cavity 29 is formed in the bottom wall of the filter box main body 1 having a rectangular parallelepiped shape and an upper surface opened. The dish portion 4 for containing the separated liquid L is formed in the upper part of the cavity portion 29, and further, the discharge pipe 9 having the switching valve 8 for discharging the separated liquid L is provided on the lowermost surface of the dish portion 4. Has been. The cavity 29 is formed to suppress the temperature rise of the separated liquid L contained in the dish 4 and prevent its evaporation.
Further, by making the outer shape of the hollow portion 29 into a substantially quadrangular pyramid shape as in the present embodiment, the air sucked into the suction port 2 collides and oil or the like does not adhere to the bottom wall. It also has a function. Therefore, the outer shape of the cavity 29 is
As in the present embodiment, it is preferable to form the oil-impregnated air from the kitchen appliance 16 into a shape that reduces air resistance so that the oil-impregnated air does not collide with and adhere to the bottom wall of the filter device F, but the present invention has this shape. Without being limited to, for example,
The outer shape of the filter device F can be appropriately changed depending on the shape of the mounting position of the filter device F, the amount of air discharged from the fan 19, and the like.

Further, the water level gauge 10 is placed at a position where the water level of the separated liquid L on the side of the suction port 2 of the partition plate 5 described later housed in the dish portion 4 can be visually observed.
Is provided.

Further, in the upper opening of the filter box body 1, two partition plates 5 are formed in order to form an intake port 2 and an exhaust port 3.
5 is erected, and a mounting flange 1 is attached to the upper end of the partition plate 5.
1 is formed. The mounting flange 11 has a plurality of bolt holes 11a bored therein.
A filter device F of this embodiment is fixed to the ceiling 32 of the kitchen by inserting and fastening a bolt (not shown) in 1a. Further, both vertical side edges 5a, 5a of the partition plate 5 are the side walls 1a, 1a of the filter box main body 1,
1a are formed so as to be in close contact with each other and are fixed to each other, and a seal member (not shown) or the like is interposed between the vertical side edge 5a of the partition plate 5 and the side wall 1a of the filter box main body 1,
It is preferable that the suction port 2 side and the discharge port 3 side are hermetically separated.

Further, the lower end edge 5b of the partition plate 5 is formed so as to be immersed in the separated liquid L contained in the dish portion 4 for a predetermined length m, and the lower end edge 5b is preferably substantially horizontal. The immersion length m is a value determined by the air discharge means, for example, the discharge air volume of the fan 19 or the size of the filter device F of the present invention, and the water level of the separated liquid L is adjusted. Therefore, the setting can be easily changed.

In this embodiment, on the downstream side of the partition plates 5 and 5,
The angle members 12, 12 having a plurality of elongated holes 12a, 12b formed on both sides are extended, and the bolts 13 are formed in the holes 5c and the elongated holes 12a formed in the partition plate 5 at positions corresponding to the elongated holes 12a. And insert the angle member 12 with the nut 14.
Have concluded. On the other hand, on the other side of the angle member 12, one end face is bent at a right angle, and a hole 7 is formed at a position corresponding to the long hole 5b of the angle member 12 on the refracting surface.
a separating plate 7 having a and having a plurality of ventilation holes 6 formed therein,
7 are fastened by bolts 13 and nuts 14.
For example, a seal member may be interposed in the mounting portion, and
It is preferable to shield S1 and the space S2.

The lower end edges 7c of the separation plates 7 and 7 are immersed in the separating liquid L deeper than the lower end edges 5b of the partition plate 5, and both vertical side edges 7b and 7b of the separation plate 7 are the grease filter box 1 Are formed so as to be in close contact with the respective side walls 1a, 1a of the. When the filter device F is operated, the separation plate 7 drains air bubbles that pass through the lower end edge 5b of the partition plate 5 further through the ventilation holes 6 to drain water.
This is for re-separating dispersed particles having a relatively large specific gravity such as oil, and for rectifying the air. Therefore, air bubbles passing through the partition plate 5 should not pass through the lower end edge 7c of the separation plate 7. Is configured.

This is because the air that has passed through the lower end edge 7c of the separation plate 7 and is guided to the discharge port 3 contains a large amount of water, and when such humid air is sucked into the smoke exhaust passage 17 or the like, Smoke exhaust 17
This is because it may cause rusting. Further, by providing the separating plate 7, dispersed particles insoluble in water such as oil are trapped between the partition plate 5 and the separating plate 7, and even if the suction force of the fan 19 is strong, the separating liquid is separated. It does not float from the L surface and is guided to the smoke exhaust passage 17.

A side window 1a of the filter box main body 1 is provided with a peep window W so that the water level when the apparatus F, which will be described later, can be visually observed.

The separation liquid L is ideally one that dissolves oil and does not ignite, but in this embodiment, water, a surfactant aqueous solution, etc. are used as familiar liquids. It should be noted that the present invention is not limited to such water and surfactants, but is configured so that the material of the separation liquid L can be selected according to the purpose of use of the filter device F. In the case of use as a separating liquid L, a conventionally known deodorizing liquid may be stored, and a type of the separating liquid L capable of suitably dissolving fine particles having a different odor generated depending on the use place such as a barn or a beauty salon may be selected. Good. In addition, when used as an indoor air purifier, the separated liquid L may be used as an fragrance to remove dust contained in the indoor air and at the same time be shared so as to supply a comfortable odor to the room. It is possible. Further, when used in a food factory or the like, it is possible to use a disinfecting liquid to capture bacteria.

Next, the operation of this embodiment will be described with reference to FIGS.

As shown in FIG. 2 (A), while the water L is being stored in the pan 4 by the predetermined amount while checking the water level gauge 10, the smoke exhaust passage 1
When a fan (not shown) provided on the outlet side of 7 is operated, the air pressure on the outlet 3 side becomes lower than the air pressure on the inlet 2 side as shown in FIG. While the water level on the discharge port 3 side rises, the water level on the suction port 2 side partitioned by the partition plate 5 falls. The suction port 2
When the water level on the side is slightly lower than the lower end edge 5b of the partition plate 5, the air containing dispersed particles of oil or the like sucked from the suction port 2 passes through the gap of the lower end 5b of the partition plate 5 and the discharge port. Guided to the 3rd side. At this time, the lower end edge 7c of the separation plate 7 is provided longer than the lower end edge 5b of the partition plate 5, and the discharge port 3
Since the water level on the side is rising, the air containing the dispersed particles passes between the partition plate 5 and the separation plate 7 while separating the dispersed particles and air from each other in water, and becomes air bubbles. Surface to the surface. The dispersed particles thus separated float on the water surface or mix in the water, while the air is guided to the space S1 on the water surface. Most of the dispersed particles are removed by such separation. According to the experimental results of this example, the trapping rate for oil was about 99%, and the trapping rate for odor was about 80%. When the disinfecting liquid was used as the separation liquid L to capture bacteria in the air, the capture rate was about 90%.

Next, when the air guided in the space S1 passes through the vent hole 6 provided in the separation plate 7, dispersed particles such as slightly remaining oil particles collide with the periphery of the vent hole 6. ,
Furthermore, oil and the like will be separated. In addition, the air is rectified when passing through the vent holes 6, and it is possible to prevent the generation of wind noise and also prevent the water from scattering on the water surface due to the turbulent flow. The air from which the dispersed particles are completely removed passes through the space S2, is guided to the exhaust port 3 → the smoke exhaust path 17, and is exhausted outdoors.

The oil floating on the water surface, the dust mixed in the water, etc. may be discarded from the drain pipe 9 together with the water L by opening the switching valve 8, while the fresh water L may be supplied from the suction port 2. It is like this. Further, such water supply / drainage of the separated liquid becomes more suitable by using an automatic water supply / drainage device described later.

Further, in this embodiment, as shown in FIG. 2 (B), since the fastening state of the partition plate 5 and the separation plate 7 is changeable by the elongated hole of the angle member 12, the fan The separation performance or the ventilation performance due to the difference in the amount of discharged air or the like can be confirmed while looking at the observation window W and finely adjusted to a suitable amount.

The present invention is not limited to the above-described embodiments, and various modifications can be considered. Other embodiments according to the present invention will be described below.

FIG. 4 is a perspective view showing a filter device according to a second embodiment of the present invention, FIG. 5 is a sectional view taken along the line VV shown in FIG. 4, and FIG. FIG. 7 is a perspective view showing such a filter device, FIG. 7 is a sectional view taken along line VII-VII shown in FIG. 6, FIG. 8 is a sectional view showing a filter device according to the fourth embodiment, and FIG. Similarly, FIG. 10 is a perspective view showing a filter device according to the fifth embodiment, and FIG.
A cross-sectional view taken along line XI, FIG. 11 is a cross-sectional view showing the filter device according to the sixth embodiment, and FIG. 12 is a circuit diagram showing an example of an automatic water supply / drainage device suitable for use in the filter device of the present invention. The same parts as those of the filter device according to the first embodiment of the present invention shown in FIGS. 1 to 3 and the conventional grease filter device shown in FIGS. 13 to 14 are designated by the same reference numerals.

First, as shown in FIGS. 4 to 5, in the filter device F according to the second embodiment, the entire filter device F is formed in a cylindrical shape, and the filter device F is provided on the bottom wall of the filter box body 1. Is formed with a conical cavity portion 29,
The dish portion 4 for containing the separated liquid L is provided on the upper part of the. Inside the filter box body 1, both ends are open and a mounting flange 11 and a plurality of bolt holes 11 are provided at the upper end.
The separation plate 7 on which a is formed is erected by fixing the connecting member 28. A plurality of ventilation holes 6 are formed in the side wall of the separation plate 7. Further, the separation plate 7
Between the filter box body 1 and the filter box body 1, there is a cylindrical partition plate 5 having both open ends, the lower end edge 5b of which is shorter than the lower end edge 7c of the separating plate 7, and the water contained in the dish portion 4 It is detachably provided so as to be immersed in L for a predetermined length m. The top plate 30 is in close contact with the mounting portion of the separating plate 7 and the partition plate 5, so that the suction port 2 and the discharge port 3 are blocked. Therefore, the air sucked from the suction port 2 is guided to the space S1 formed between the separation plate 7 and the partition plate 5 after passing through the lower end edge 5b of the partition plate 5, and then to the water surface of this space S1. After floating, the air passes through the ventilation hole 6 and is guided to the smoke exhaust path 17 from the exhaust port 3.

According to this structure, the upper opening of the cylindrical separation plate 7 serves as the discharge port 3, the gap between the filter box body 1 and the partition plate 5 serves as the suction port 2, and the mounting flange 11 serves as a fan or the like. When the fan is operated by attaching it to the opening of the ceiling, the same operational effect as that of the first embodiment is exhibited.

Further, as shown in FIGS. 6 to 7, the filter device F according to the third embodiment is a modification in which the positions of the suction port 2 and the discharge port 3 are reversed from each other, and a filter box On the bottom wall of the main body 1, a hollow portion 29 having a substantially quadrangular pyramid shape is formed,
A dish 4 for containing the separated liquid L is provided above the cavity 29. Further, a partition plate 5 is erected in the filter box body 1, and a lower end edge 5b of the partition plate 5 is immersed in the separated liquid L contained in the dish portion 4 for a predetermined length m. Further, the partition plate 5 forms the intake port 2 and the discharge port 3 in a state of being shielded from each other, and the partition plate 5 is provided outside the partition plate 5, that is, on the discharge port 3 side.
Separation plates 7 that are deeper than the lower end edge 5b of the are separated. The separating plate 7 is provided with a plurality of ventilation holes 6 for rectifying the air that has passed through the lower end edge 5b of the partition plate 5 and finally separating the dispersed particles contained in the air. It has a function. A space S1 is formed between the separation plate 7 and the partition plate 5.

Even in the case of such a configuration, as shown in FIG. 7, when exhausted by a fan or the like (not shown) provided on the discharge port 3 side, the water level on the suction port 2 side at the central portion of the filter box body 1 is lowered, The water level on the outside of the discharge port 3 rises, and the present embodiment has the same effect as the first embodiment. Such a filter device F is suitable for use in, for example, a smoke exhaust device provided in a cooking table.

Various modifications are conceivable depending on the shape of the kitchen using the filter device F of the present invention. In the fourth embodiment shown in FIG. 8, the fan 19 is installed on the vertical wall 31. Therefore, the filter device F of the first embodiment is vertically cut in half, and the mounting flange 11 on the upper part of the partition plate 5 is fixed to the ceiling 32, while the filter box body 1 is fixed to the vertical wall 31.
It is configured to stick to. Further, the lower end edge 5b of the partition plate 5 is formed shorter than the lower end edge 7c of the separation plate 7,
The lower edge 5b of the partition plate 5 is immersed in the separated liquid L contained in the dish 4 for a predetermined length. Further, the separation plate 7 is provided with a plurality of ventilation holes 6, and the air that has passed under the lower edge 5b of the partition plate 5 passes through the space formed between the partition plate 5 and the separation plate 7. After being guided to S1, this vent hole 6
The rectification and the final separation of dispersed particles contained in the air are carried out by passing through.

Also in such a configuration, when the fan 19 is operated, the water level of the separated liquid L on the suction port 2 side is lowered to the lower end edge 5b of the partition plate 5 from the suction port 2 as in the first embodiment. The sucked air submerges in this gap and floats on the water surface of the space S1. At this time, most of the dispersed particles are dissolved in the separation liquid L, or separated, and further, the dispersed particles remaining in the air floating on the water surface of the space S1 are vent holes of the separation plate 7. When passing through 6, they will be further separated by collision. Since the air is rectified at the same time when passing through the air holes 6, water drops are not scattered by the suction force of the fan 19 from the water surface of the space S1 or the space S2. It is also suitable for rusting around. Further, since such a filter device F can be extremely easily downsized in terms of its configuration, it is suitable for use in a kitchen of a general household, for example.

Furthermore, as shown in FIGS. 9 to 10, in the fifth embodiment of the present invention, the filter device F includes a dish portion 4 for containing the separated liquid L and the dish portion 4 on both vertical sides thereof. The partition plate 5 to which the lower part of the rim 5a is fixed, and the first separation plate fixing member 33 having the partition plate 5 mounted and having the mounting flange 11 at one end.

The dish portion 4 is formed to have a relatively shallow accommodation depth so that the suction port 2 has a larger area than that of the first embodiment. Further, the side wall 1a of the filter box main body 1 is cut off at the suction port 2 so that air can be sucked from both the A direction and the B direction shown in FIG. By increasing the opening area of the suction port 2 and the suction direction in this way, the dust removal speed of the filter device F can be improved. The configuration for increasing the opening area in this way is not limited to the present embodiment, but can be applied to the first to fourth embodiments. Further, the reason why the dish portion 4 of the present embodiment is not formed with a quadrangular pyramidal cavity is that the present embodiment is, for example, the eleventh embodiment.
As shown in the figure, it is effective when it is used as a floor-standing type filter device F. Therefore, when it is used as the filter device F of the type that is attached to the ceiling part of the kitchen as described above, it is a quadrangular pyramid-shaped cavity. It is preferable to form the portion 29. Further, such a floor-standing type filter device F
In that case, the cavity portion 29 having a flat bottom wall may be formed.

The first separating plate fixing member 33 is for attaching a mounting flange 11 for bolting to the ceiling 32 or the like, a bolt hole 11a formed in the mounting flange 11, and an upper end of the partition plate 5 described later by bolting. The bolt hole 11b and the holding portion 35 that holds the upper end of the separation plate 7 are bent into a predetermined shape. The two first separating plate fixing members 33 and 34 are provided on the side wall 1 of the filter box body 1.
By being fixed to a, the filter box body 1 is formed together with the dish 4.

On the other hand, the separating plate 7 is composed of a porous body having a large number of continuous holes 6, and specifically, it is preferable to use a ceramic foam material for the porous body. More specifically, alumina, zirconia,
It is preferable that the porosity is 70% or more, such as a ceramic formed of a material such as zirconium armlite.
The pore size depends on the suction force of the fan 19 used and the type of dispersed particles to be removed, but when removing dispersed particles having a large particle size such as oil, ceramic foam having a relatively large pore size is usually used. For the removal of fine particles such as odor, it is preferable to use a ceramic foam material having a relatively small pore size. For example, if the number of cells formed by the skeleton of ceramics arranged in a line of 1 inch is defined as the number of cells, a ceramic foam with 6 cells is used to remove dispersed particles having a relatively large particle size such as oil. For the material, and for removing fine particles such as odor, a ceramic foam material having a cell number of 40 is suitable. The porous body that can be used for the separation plate 7 is not limited to the ceramic foam material, and an organic material such as a porous film of a polymer material or a metal material such as foam metal can also be used. .
Which of these inorganic materials, organic materials and metallic materials is selected is determined by the type of dispersed particles to be removed, the particle size and the like. Therefore, in this embodiment,
By changing the material of the separation plate 7 held by the first and second separation plate fixing members 33, 34, a filter device F capable of removing any particles such as oil, odor, dust, bacteria, etc. It has excellent properties.

The lower end edge of the second separating plate fixing member 34 is partially notched, and is fixed to the dish portion 4 at a portion not notched.

The partition plate 5
Has a bolt hole (not shown) at its upper end,
Bolt hole 11 provided in the first separating plate fixing member 33.
The partition plate 5 is fixed to the filter box main body 1 by penetrating a bolt to b. If both bolt holes are formed as long holes, the immersion depth m of the partition plate 5 in the separated liquid L can be finely adjusted. In addition, it is preferable that a seal member or the like is interposed in the mounting portion between the partition plate 5 and the separating plate 7 so that air does not enter through the gap between the mounting portions. Further, the second separating plate is fixed. The height of the notch of the notch portion 36 of the member 34 is set such that the air that has passed through the lower end edge 5b of the partition plate 5 from the notch portion 36 does not directly float to the space S2. It is preferable to form it so that it is more deeply immersed in the separation liquid L.

Further, the separation plate 7 includes a first separation plate fixing member 33 and a second separation plate fixing member 33.
The separation plate fixing member 34 holds the top and bottom of the separation plate fixing member 34, and the pressing member (not shown) attached to the partition plate 5 makes the first
The filter box body 1 is pressed and held toward the center of the upper filter box body 1.

In this embodiment configured as described above, when a fan (not shown) is operated, the water level of the separated liquid L on the suction port 2 side is lowered, and the air is discharged from the lower end edge 5b of the partition plate 5 into the space S1. Surface to the surface. At this time, in this embodiment, since the opening area of the suction port 2 is formed large, a large amount of air can be sucked in from all directions.
Then, most of the dispersed particles contained in the air introduced into the space S1 are dissolved in the separation liquid L when passing through the separation liquid L, or are separated.
Furthermore, when passing through the separating plate 7 made of a ceramic foam material, the slightly remaining dispersed particles are also separated here, and at the same time, the air is rectified when passing through the pores 6 of the porous body. Become. As a result, the dispersed particles contained in the intake air are preferably removed, and the air guided to the discharge port 3 is rectified, so that noise can be prevented and the separated liquid L can be prevented from scattering from the water surface. it can.

Such a filter device F can be easily miniaturized, and can be installed, for example, as a deodorizing device in a room on the floor or at another desired place. The structure of the filter device F configured as in the sixth embodiment is not limited to that of the fifth embodiment, and any of the first to fourth embodiments described above is possible. However, when a fan is directly attached to the filter device F of the first to fourth embodiments to form a simple filter device, the hollow portion 2
It is preferable to form the bottom wall of 9 into a flat shape so that it can be installed on the floor or the like. Further, it goes without saying that the device F is not limited to a deodorizing device and can be used as an air purifier.

In the automatic water supply / drainage device suitable for use in the filter device F of the present invention shown in FIG. 12, when the overflow pipe 40 is fixed to the dish portion 4 of the filter device F and the water level becomes equal to or higher than a predetermined level.

Is connected, the signal is transmitted to the solenoid valve 42, and the supply pipe 41 is opened for 5 minutes. Further, after the lapse of 5 minutes, the operation relay 54 is disconnected and the water supply is stopped. Therefore, if such an automatic water supply / drainage device is provided in the filter device F of the present invention, water supply and drainage can be automatically performed, and the filter device of the present invention will exhibit further excellent effects.

The present invention is not limited to the specific examples described above, and various modifications are conceivable. The purpose of use, the structure of the filter device, the type of the separation liquid, etc. may be changed depending on the place of use. It may be changed accordingly. Such versatility is also one of the features of the present invention.

[Effects of the Invention] As described above, according to the filter device of the present invention, the intake air containing dispersed particles is made to pass through the separated liquid contained in the filter box body, and is made to pass through the ventilation holes of the separation plate. As a result, the dispersed particles can be completely removed from the air, the air can be rectified by the ventilation holes, and the separated liquid can be prevented from scattering. Therefore, it becomes possible to remove the dispersed particles regardless of the type of the dispersed particles, and it is possible to provide a filter device having excellent removal performance. Moreover, it also has an effect of preventing noise and scattering of the separated liquid. In particular, since the separation plate is arranged such that its ventilation holes are oriented in the lateral direction, the water droplets wound up in the space formed between the partition plate and the separation plate are separated by the inertial force of the separation plate. It is less likely that the separated liquid will flow to the outlet side through the ventilation hole, and the separated liquid is further prevented from scattering.

Further, since the dispersed particles that have been removed and the fire of the kitchen are completely separated by the separated liquid, fire resistance is improved.

Furthermore, the dispersed particles that have been removed can be discarded simply by exchanging the separated liquid, and the cleanability is greatly improved, which is a great practical effect.
