Description

  The present invention relates to removal of dirt on a filter attached to a range hood.

  Conventionally, a filter or a baffle plate or the like has been attached to a range hood for the purpose of collecting oily smoke or dust generated by cooking. Since the filter and the baffle plate are contaminated with use, the oil smoke collecting performance is deteriorated and the oil dripping occurs from the collecting portion, so that it is necessary to perform regular cleaning.

  Further, as a means for automatically purifying the filter for the purpose of reducing the labor of cleaning, there is a method of removing dirt by centrifugal force by attaching a driving means to the filter and rotating it (for example, Patent Document 1). reference).

  Hereinafter, the exhaust device will be described with reference to FIG.

As shown in FIG. 4, the filter 102 is disposed in front of the exhaust fan 101, and includes a drive device 103 that rotates the filter 102 and a sensor 104 that detects the dirt on the filter 102, thereby removing the dirt on the filter 102. The filter 102 is rotated by the driving device 103 by detecting, and the dirt is removed by centrifugal force.

(Embodiment 1)
As shown in FIG. 1, a hood 2 provided with a suction port 1 for collecting oil smoke generated from the cooker and dust floating around the cooker (not shown) is installed above or around the cooker (not shown). The hood 2 is provided with a discharge port 4 that communicates with the outside via a duct 3 that communicates with the outside, and an exhaust fan 6 having a rearward blade shape is disposed inside the blower casing 5. The ventilation path 7 which connects the suction inlet 1 and the discharge outlet 4 via is formed. Further, a rectifying plate 9 connected to the rectifying plate driving motor 8 is disposed near the suction port 1 in the hood 2 and exhausted into the clean casing 10 in which the hydrophilic treatment or the water repellent treatment in the ventilation passage 7 has been performed. A filter 11 that has been subjected to hydrophilic treatment or water repellent treatment and a water conditioning plate 12 that has been subjected to hydrophilic treatment or water repellent treatment are disposed at a predetermined distance from the rotation axis of the drive motor 13 in front of the fan 6. It is fixed while keeping. Further, on the same axis as the drive motor 13, a watering means 17 including a watering nozzle 16 connected by a watering device 14 and a water supply pipe 15 is configured. Further, a small hole 10a is formed in the lower end portion of the clean casing 10, and a small hole 5a is formed in the lower end portion of the blower casing 5, and a waste container 18 as a waste collecting means is provided in the lower portion thereof.

  FIG. 2 shows a configuration diagram of the filter 11 and the water conditioning plate 12 of FIG.

  In the above configuration, when cooking with a cooker, during operation of the exhaust fan 6, oily smoke and dust are sucked into the hood 2 from the suction port 1 of the hood 2 and collected by the filter 11. When cleaning is performed after the operation of the exhaust fan 6 is stopped, the watering device 14 of the watering means 17 is moved to spray or spray the filter 11 and the water conditioning plate 12 from the watering nozzle 16, and the filter 11 and water conditioning are driven by the drive motor 13. The plate 12 is rotated. Then, the dirt adhering to the filter 11 is easily peeled off by watering or spraying, and further, by rotating the filter 11 and the water conditioning plate 12, the centrifugal force and the surface are supplied to the water conditioning plate 12 having an uneven shape. As the water collides with the front and back surfaces of the filter 11, the dirt adhering to the filter 11 is scattered and adheres to the inner surface of the clean casing 10. Since the inner surface of the clean casing 10 has been subjected to a water repellent treatment, the dirt flows downward and drops into the waste container 18 via the small hole 10 a at the lower end and the small hole 5 a at the lower end of the blower casing 5. The dirt when it cannot adhere with the filter 11 adheres to the exhaust fan 6, adheres to the inner surface of the blower casing 5 by the rotation of the exhaust fan 6 itself, and the inner surface of the blower casing 5 is also subjected to hydrophilic treatment. The dirt flows downward and drops to the waste container 18 through the small hole 5a at the lower end of the blower casing 5. Further, at this time, the rectifying plate drive motor 8 is driven and the rectifying plate 9 closes the ventilation path 7, so that water passing through the ventilation path 7 leaks to the outside of the hood 2 by watering or spraying by the watering device 14. Since the lower surface of the hood 2 and the water conditioning plate 12 are flush with each other, the cleaning can be easily performed in less time than the conventional shape.

  The cleaning at this time can be automatically operated by a control means for controlling the rotation time and the rotation speed of the filter 11 and the water conditioning plate 12 according to the amount of dirt and the interval with the previous cleaning time.
