  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Embodiment 1)
As shown in FIG. 1, in the first embodiment, a square shape that collects oil smoke generated from the kitchen appliance, dust floating in the surroundings, etc. above a kitchen appliance (not shown) such as a gas stove or IH cooker. A hood 2 provided with a suction port 1 around the rectifying plate 9 is installed on a wall surface 19 with screws or the like, and a discharge port 4 communicating with the outside through a duct 3 provided on the top surface of the hood 2 is provided. 2, an impeller 6, which is a sirocco fan, for example, is provided with a metal oil collecting mechanism 5 on a circumferential surface on a rotating shaft (not shown) of an electric motor 20 provided in the vicinity of the discharge port 4. A cleaning tank 7 including a structure in which the suction port 1 is rotatably installed is provided, and a ventilation path 8 that connects the suction port 1 and the discharge port 4 via the impeller 6 is formed.

  Further, a water storage device 11 for storing the cleaning liquid 10 and a water supply pump 12 are provided on the side of the wall surface 19 below the cleaning tank 7, and are connected by the water supply pump 12 and are sprayed between the cleaning tank 7 and the impeller 6. The nozzle 13 constitutes watering means 14.

  In addition, a guide 15 for guiding the discharge of the cleaning liquid 10 (for example, about 40 ° C. hot water) is provided in the cleaning tank 7, and a drain hole 16 is provided at the lower end of the cleaning tank 7 to open and close the storage of the cleaning liquid 10. A recovery mechanism 18 is provided that recovers sewage scattered in the cleaning tank 7 below the on-off valve 17.

  As shown in FIG. 2, the guide unit 15 has a configuration in which a convex shape portion (for example, a throttle shape) having a convex shape in the top surface direction of the hood 2 is provided in the cleaning tank 7, and the convex shape portion is drained. An inclined portion 21 that is inclined toward the hole 16 is formed.

  In the above configuration, the drain hole 16 is closed with the on-off valve 17 so that the wind generated from the impeller 6 does not leak out of the ventilation path 8 when cooking or ventilating with a kitchen appliance.

  Then, when the electric motor 20 is energized and the impeller 6 starts to rotate via the rotating shaft of the electric motor 20, the oil smoke and dust are sucked from the suction port 1 and pass through the rectifying plate 9 and pass through the hood 2, Dust and the like go to the impeller 6 and are collected by the oil collecting mechanism 5.

  When cleaning the oil collecting mechanism 5, first, the impeller 6 rotates, and the water collecting nozzle 13 sprays water onto the oil collecting mechanism 5 to clean the surface of the oil collecting mechanism 5. Is closed by the on-off valve 17 to store the cleaning liquid 10 in the cleaning tank 7 and immerse the oil collecting mechanism 5.

  Then, the cleaning liquid 10 containing oily smoke, dust and the like peeled off by the water spray opens the on-off valve 17 and flows toward the drainage hole 16 while being in contact with the guide portion 15 in the cleaning tank 7. And is recovered to the recovery mechanism 18 below.

  Further, a convex guide portion 15 is provided in the cleaning tank 7 and an inclined portion 21 that is inclined toward the drain hole 16 is provided.

  With such a configuration, as shown in FIG. 2, the flow of the cleaning liquid 10 flows along the inclined portion 21 while being in contact with the guide portion 15, and therefore the drain hole 16 provided at the lower end portion in the cleaning tank 7. In addition, since the cleaning liquid 10 can be guided more easily, the residual water in the cleaning tank 7 is reduced, and the generation of residual water noise can be reduced even if the impeller is rotated.

  Also, as shown in FIG. 3, when the cleaning liquid 10 is discharged, the cleaning liquid remaining in the cleaning tank 7 without contacting the guide portion 15 is then rotated when the impeller 6 is rotated for cooking or ventilation. The wind generated from the impeller 6 moves clockwise along the cleaning tank 7.

  And the washing | cleaning liquid 10 of the right half surface of the washing tank 7 contacts the guidance | induction part 15 after a movement, and is discharged | emitted by the wind force to the drain hole 16 along an inclined part.

  On the other hand, the cleaning liquid 10 on the left half surface of the cleaning tank 7 is pushed up along the cleaning tank 7 by the force of wind.

  Thereafter, when the rotation of the impeller 6 is stopped and cooking or ventilation is finished, the pushed cleaning liquid 10 moves to the lower end portion along the cleaning tank 7 by gravity, and is in contact with the inclined portion of the guide portion 15 while draining. Therefore, even if the impeller is rotated, the generation of residual water noise can be reduced.

Further, as shown in FIG. 3, the cleaning liquid 10 moves in such a manner that a part of the oil smoke collected by the oil collecting mechanism 5 is blown in the circumferential direction by the centrifugal force of the impeller 6 and is moved to the cleaning tank 7. It is also effective against accumulated oil.

  Since the range hood according to the present invention can reduce the generation of residual water noise even when the impeller is rotated, the range hood can also be applied to a ventilation device or the like that collects dirt. .
