However, the oil fumes discharged from the second connection chamber 22 are those in which oil particles have been removed in the casing 3.

To the casing 3, a cleaning liquid is supplied to the inside of the casing 3 so that the oil fine particles adhering to the vane plate 10,
A cleaning unit 30 is provided for cleaning oil and fat adhering to the inside of the casing 3 and the inside of the first and second connection chambers 20 and 22. That is, the box-shaped cleaning liquid tank 3 is provided above the lid 5 of the casing 3 via the legs 32 standing upright at the four corners of the lid 5.
1 is provided, and a cleaning liquid for cleaning the oil fine particles adhering to the blade plate 10 and the oil and fat adhering to the casing 3 and the like is stored in the cleaning liquid tank 31. Also,
A pipe 33 reaching the inside of the casing 3 from the cleaning liquid tank 31 is provided on the lower surface of the cleaning liquid tank 31, and the pipe 33 is provided with a valve 34. By operating the valve 34, the cleaning liquid is supplied from the cleaning liquid tank 31 to the inside of the casing 3. Can be injected into. Here, the cleaning means 30 is configured to include the cleaning liquid tank 31, the pipe 33, and the valve 34. As the cleaning liquid, a surfactant such as a liquid synthetic detergent is used.

In the lower part of the casing 3, the fine oil particles adhering to the blade plate 10 become coarse particles with the passage of time, and the separated oil that has fallen from the blade plate 10 to the bottom of the casing 3 and accumulated and the use inside the casing 3 A treatment liquid discharge means 40 for discharging the already-washed cleaning liquid is provided. The treatment liquid discharge means 40 is configured to include a pipe 41 provided so as to project downward from the horizontal portion 4B of the bottom plate 4 of the casing 3 to the outside of the casing 3, and the pipe 41 includes a valve 42. Further, below the treatment liquid discharge means 40 or at a predetermined place, a treatment tank or the like (not shown) for treating the separated oil or the used cleaning liquid is provided.

Next, the operation of this embodiment will be described. Before using the kitchen equipment, the blade 12 is rotated in the casing 3 by driving the motor 12. At this time, a predetermined cleaning liquid is stored in advance in the cleaning liquid tank 31, and
The valve 34 of the cleaning means 30 is closed and the valve 42 of the processing liquid discharge means 40 is also closed. Further, the buoyancy body 27, together with the water sealing valve 24, is supported at the upper portion by the engagement of the slide rod 25 and the guide hole 23B of the lid 23, and is positioned on the bottom surface of the first connection chamber 20 by its own weight.

By using the kitchen equipment, oil smoke containing oil particles or the like flows through the exhaust duct 6 of the exhaust system path A, and this oil smoke is opened from the opening 45A of the oil smoke introduction passage 19 to the opening of the first connection chamber 20. It is introduced into the first connection chamber 20 through the portion 23A, and is introduced into the casing 3 from the opening 20A of the first connection chamber 20 and the opening 3A of the casing 3. The oil particles in the oil smoke adhere to many grooves 16 on the surface of the rotating blade plate 10. The oil fine particles gradually become coarse particles with the lapse of operating time, and are discharged into the inside of the casing 3 by the centrifugal force due to the rotation, and the released oil flows as separated oil through the inclined portion 4A of the bottom plate 4 of the casing 3 to store the oil. Gather in the horizontal section 4B. When a predetermined amount of separated oil accumulates in the horizontal portion 4B, the valve 42 of the processing liquid discharge means 40 is opened each time the kitchen equipment is in use, and the separated oil is stored in the processing tank outside the casing. Discharge. Then, the oil smoke from which the oil particles have been removed in the casing 3 becomes, so to speak, a clean exhaust gas, and the second connection chamber 22 and the oil smoke discharge passage 21.
To the exhaust duct 6 and then into the atmosphere.

The cleaning of the casing 4 and the vane plate 10 is performed when the use of the kitchen equipment is stopped. First, after confirming that the driving of the motor 12 is stopped and that the valve 42 of the processing liquid discharge means 40 is closed, the cleaning means 30
The valve 34 is opened to inject the cleaning liquid in the cleaning liquid tank 31 into the casing 3. When the liquid level of the cleaning liquid rises, the cleaning liquid is communicated with the casing 3 in the first and second connection chambers 20 and 2.
It also penetrates into 2. Then, as the liquid surface of the cleaning liquid further rises, buoyancy is generated in the buoyancy body 27.
7 and the water seal valve 24 gradually rise until finally the water seal valve 24
Closes the openings 45A and 23A of the passages 19 and 21 and the connection chambers 20 and 22, respectively, so that the casing 3 and the first and second connection chambers 20 and 22 are filled with the cleaning liquid. . When the buoyancy body 27 and the like are raised, the slide rod 25 is guided by the guide hole 23B of the cover plate 23 and slides upward.

After the casing 3 is filled with the cleaning liquid, the valve 34 of the cleaning means 30 is closed to stop the supply of the cleaning liquid, and then the motor 12 is driven to rotate the blade plate 10. As a result, the oil particles adhering to the blade plate 10 and the oil and fat adhering to the inner wall surfaces of the casing 3 and the first and second connection chambers 20 and 22 are washed in a short time. After the cleaning is completed, the valve 42 of the processing liquid discharge means 40 is opened, and the processing liquid after the cleaning processing is discharged to the processing liquid tank or the like outside the casing.

According to this embodiment as described above, the following effects can be obtained. That is, in the oil smoke containing oil particles discharged from the kitchen equipment, the oil particles are removed by the oil particles adhering to the many grooves 16 of the blade 10 in the casing 3. Therefore, from the casing 3 to the oil smoke discharge passage 2
1. The oil smoke discharged to the exhaust duct 6 is clean and does not contain oil particles, and this clean oil smoke is discharged into the atmosphere, which has an effect of preventing air pollution.

Further, twelve blades 10 are used as the oil particle adhering members, and a large number of fine grooves 16 are formed as oil particle adhering portions on each blade 10, so that the surface area of each blade 10 is large. In addition, since the blades 10 are rotated, the adhering efficiency of the oil particles is increased, and the oil particle removing effect is increased. Further, the horizontally long square holes 50 formed on the surface of each blade 10 have different vertical forming positions,
Moreover, since the width and the length are different as necessary, the oil smoke flowing in the casing 3 can be turbulently flowed, and thereby the efficiency of adhering the oil fine particles to the blade plate 10 can be increased, and The number of times of contact with each blade 10 can be increased, and the oil removal efficiency can be improved.

The oil smoke introduction passage 19 and the oil smoke discharge passage 2 are also provided.
1 is of a size that can be connected to the exhaust duct 6 of the exhaust system path A, and the vane plate 10 inside the casing 3 is radial to the upper and lower support plates 14.15 attached to the rotating shaft 11, and 12 and the like. Since it is arranged in minutes, it is compactly assembled, and as a result, the entire oil mist removing device 1 can be made compact. Further, the oil smoke flowing in the casing 3 adheres to a large number of fine grooves 16 as oil fine particle adhering portions of the rotating blade plate 10 and drops into the casing 3 by centrifugal force.
Therefore, the oil fine particles are not accumulated in the oil mist, so that the blade plate 10 can be rotated for a long time, that is, the oil mist removing device 1 can be used for a long time. Further, since the bottom plate 4 of the casing 3 is formed with the inclined portion 4A, the separated oil that has fallen inside the casing 3 easily flows due to the centrifugal force of the rotation of the blade plate 10, and the bottom plate 4 has an oil storage portion. Since the horizontal portion 4B is formed, the separated oil that flows through the inclined portion 4A easily accumulates in the horizontal portion 4B, and thus the oil storage portion can be easily provided.

Further, the separated oil accumulated in the horizontal portion 4B of the casing 3 can be discharged by the treatment liquid discharge means 40 at any time, so that the separated oil does not accumulate and adhere to the blade plate 10. Thus, the oil mist removing device 1 can be used for a long time, and the removal effect can be prevented from lowering. Since the processing liquid discharging means 40 can discharge the processing liquid after the cleaning processing in addition to the separated oil, it is not necessary to provide a discharging means dedicated to each of the cleaning liquids, whereby the structure of the apparatus can be simplified. There is also the effect.

The vane plate 10 and the inside of the casing 3 are washed with the washing liquid from the washing liquid tank 31 to the casing 3 at any time by operating the valve 34 of the washing means 30.
After the cleaning liquid is poured into the casing 3 and the casing 3 is filled with the cleaning liquid, it can be performed only by rotating the blade plate 10 by driving the motor 12, so that the interior of the blade plate 10 and the casing 3 can be easily cleaned. Therefore, the blade plate 10 can be repeatedly used in a state where oil particles are easily attached.

Further, the water sealing valve 24 provided in the first and second connecting chambers 20, 22 is engaged with the buoyant body 27, and the water sealing valve 24 is the first and second connecting chambers 20, 22. When the cleaning liquid is not present in the casing 3, it is located on the bottom surface 20A, 22A side of each connection chamber 20, 22, and when the cleaning liquid is supplied to the casing 3 and each of the connection chambers 20, 22, it floats. The connection chambers 20 and 22 and the openings 23A and 45A of the passages 19 and 21 can be closed easily and reliably. Therefore, the cleaning liquid does not scatter toward the oil smoke introduction passage 19 and the oil smoke discharge passage 21 side, and the cleaning liquid does not drip from the connecting portion with the exhaust duct 6 or the like, and the use of the cleaning liquid is prevented. In addition, water seal valve 2
Since No. 4 is located on the bottom surface 20A, 22A side when there is no cleaning liquid in the first and second connection chambers 20, 22, there is also an effect that it does not hinder the flow of oily smoke. Furthermore, the first
Since the bottom surfaces 20A and 22A of the second connection chambers 20 and 22 are inclined surfaces, the blade plate 1 is placed inside the first and second connection chambers 20 and 22.
The separated oil dropped by the centrifugal force of 0 rotation and the cleaning liquid after cleaning the vane plate 10 and the like easily flow to the casing 3 side, whereby the separated oil and the cleaning liquid flow through the first and second connection chambers 20 and 22.
