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

(Embodiment 1)
As shown in FIG. 1 and FIG. 2, a hood 3 provided with a suction port 2 that is installed above or around the cooking device 1 and sucks air containing oil smoke generated during cooking or dust floating around is installed. A fan box 5 provided with a discharge port 4 communicating with the outdoors is provided, and a fan casing 8 including an exhaust fan 6 for exhaust air and an exhaust motor 7 is provided inside the fan box 5. The exhaust fan 6 is composed of a sirocco fan, for example, and forms an exhaust ventilation path 9 that connects the suction port 2 to the discharge port 4. In addition, a disc-shaped filter 11 rotated by the filter driving motor 10 and a filter fixing plate 12 for fixing the filter driving motor 10 are provided on the downstream side with respect to the direction of the exhaust flow of the suction port 2. With respect to gravity, the upper end is a fulcrum and the lower end is detachable. For example, the upper end of the filter fixing plate 12 is configured to be hooked on a hooking portion 13 provided inside the fan box 5. The lower end of the filter fixing plate 12 is fixed using a latch or the like. In addition, it is good also as a structure fixed using a screw | thread. Further, a waste container 14 for collecting oil collected by the filter 11 is provided on the lower surface of the fan box 5.

  According to such a configuration, during cooking, the smoke and dust are sucked into the hood 3 from the suction port 2 by the operation of the exhaust fan 6 and collected by the filter 11. In order to remove oil adhering to the filter 11, the filter 11 is rotated at a high speed by the filter drive motor 10, the oil is removed from the filter 11 by centrifugal force, and the removed oil is connected to the inside of the fan box 5. Specifically, it is collected into a waste container 14 on the lower surface of the fan box 5. Also, during maintenance such as cleaning, the filter 11 can be easily removed from the lower portion of the hood 3 because the filter 11 is attached obliquely so that the filter 11 faces the floor surface. Maintenance can be easily performed by becoming easy to take. Further, when the exhaust fan 6 is removed, as shown in FIG. 3, the lower end of the filter fixing plate 12 is released, and the upper end of the filter fixing plate 12 is rotated as a fulcrum so that the filter fixing plate 12 is vertical. The exhaust fan 6 can be moved in the direction of the filter fixing plate 12 by the space formed between the filter fixing plate 12 and the blower casing 8 and taken out from the suction port 2. For this reason, maintainability, such as removal of the filter 11 and the exhaust fan 6, can be improved. Further, since the filter 11 and the filter fixing plate 12 are attached obliquely so as to face the floor surface, the space for installing the exhaust fan 6 can be widened, and a thick small-diameter sirocco fan or the like can be installed. If it becomes possible, the lower surface of the hood 3 can be made flat to improve the design. Further, as other advantages, the fan box 5 can be downsized by installing a small-diameter sirocco fan or the like, so that it is possible to secure duct duct space above the range hood and improve workability. . Furthermore, since the filter 11 is provided obliquely so as to face the floor, the distance between the exhaust fan 6 and the filter 11 can be increased, and the flow is disturbed by passing through the filter 11 and is sucked into the exhaust fan 6. And noise can be reduced.

  Further, a configuration may be adopted in which a lower portion of the filter 11 is covered and a cleaning tab 15 that can store water, a water supply tank 16 that stores water used in the cleaning tab 15, and a water supply means 17 that supplies water are provided. Thus, when removing oil adhering to the filter 11, water can be accumulated in the cleaning tab 15 from the water supply tank 16 by the water supply means 17, so that a part of the filter 11 is immersed in water, and the oil etc. can be lifted and easily dropped. The cleaning effect can be improved.

  Further, a configuration may be adopted in which a nozzle 18 that jets water toward the filter 11 is provided. Thus, when removing oil or the like adhering to the filter 11, water is supplied from the water supply tank 16 to the nozzle 18 by the water supply means 17, and water is jetted from the nozzle 18 toward the filter 11 to adhere to the filter 11. Since the oil can be blown by impact by hitting water against the oil being washed, the cleaning effect can be further improved.

  In the first embodiment, water is used for cleaning the filter 11, but the cleaning ability can be further improved by using hot water, lukewarm water, or other liquids that improve the cleaning effect.

  The range hood according to the present invention can automatically clean the filter, has good maintainability such as removal of the filter or exhaust fan, and can improve the design. It is useful as an exhaust device.
