Description

  The present invention relates to a water supply unit that supplies water to a range hood having a cleaning function.

  Conventionally, this type of range hood is provided with an oil collecting mechanism for the purpose of collecting oily smoke, dust, and the like generated during cooking. Since the oil collecting mechanism part is contaminated with use, the performance deteriorates or oil dripping occurs from the collecting part, so it is necessary to periodically clean the oil collecting mechanism part. The same applies to the impeller provided for exhaust.

  In addition, as a means for automatically purifying the oil collecting mechanism for the purpose of reducing the time and effort of cleaning, there is a method of removing dirt by centrifugal force by attaching and rotating a drive device to the oil collecting mechanism. There is also a method of putting water into the water supply unit, injecting water into the oil collecting mechanism unit, and washing (for example, see Patent Document 1).

  Hereinafter, the range hood will be described with reference to FIG.

  As shown in FIG. 4, the dirty air 101 passes through the suction port 102, passes through the filter 104 disposed in front of the exhaust fan 103, and the driving device 105 that rotates the filter 104 and the filter 104 are dirty. And the sensor 106 for detecting the contamination of the filter 104, the filter 104 is rotated by the driving device 105, and the contamination is removed by centrifugal force.

  The cooker hood according to claim 1 of the present invention is arranged above or around the cooker and communicates with a suction port for sucking contaminated air and a ventilation casing containing an exhaust device for exhaust ventilation. A hood provided with an oil collecting mechanism section that is rotated by driving means in the ventilation path, a cleaning casing for immersing the oil collecting mechanism section, a nozzle that supplies water to the cleaning casing, and the nozzle A water supply unit for supplying water to the cleaning casing, and a means for collecting sewage scattered in the cleaning casing, and the oil collecting mechanism unit that collects dirt on the exhaust impeller of the exhaust device is integrally provided, The water supply part is composed of a tray part for storing water and a lid part that covers the tray part provided with an opening part for inserting a water supply path to the nozzle. The water shaking prevention rib part With a digit, that the structure. As a result, when the water supply unit is attached to the range hood, the water accumulated in the tray unit sways, and the water that undulates collides with the water swell prevention ribs provided in the lid unit, making the large water sway small. Therefore, when the water supply unit is attached to the main body, there is an effect that water can be prevented from spilling and becoming unstable.

  Moreover, you may make it the structure that the water shaking prevention rib part was provided in the circumference | surroundings of the opening part. As a result, when the water supply unit is attached to the range hood, the water accumulated in the tray unit sways, the undulating water collides with the water swell prevention ribs provided in the lid unit, and a large amount of water sways with respect to the entire opening. Therefore, there is an effect that water leakage from the opening can be suppressed.

  Further, a configuration in which a plurality of water shaking prevention rib portions are provided may be employed. As a result, when the water supply unit is attached to the range hood, the water accumulated in the tray unit sways, and the undulating water collides with the water sway prevention rib provided in the lid unit, further reducing the large water sway. As a result, the effect of collision of undulating water is increased, water fluctuation can be suppressed, and the water supply section can be more stably mounted.

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

(Embodiment 1)
As shown in FIG. 1 to FIG. 3, a cooker (not shown) has a suction port 1 that collects oily smoke generated by cooking and minute objects that are dust floating around the cooking appliance (not shown). The hood 2 is provided on the front side of the hood 2, and the hood 2 is provided with a discharge port 4 that communicates with the outside via a duct 3 that communicates with the outside. A blower casing 6 including the impeller 5 is disposed, and a ventilation path 7 that connects the suction port 1 and the discharge port 4 via the exhaust impeller 5 is formed.

  A flat rectifying plate 8 is provided in the vicinity of the suction port 1 in the hood 2, and an oil collecting mechanism for collecting oil and dust is provided in the exhaust impeller 5, A cleaning casing 10 for immersing the exhaust impeller 5 is provided below the outside of the exhaust impeller 5, and a nozzle 11 is provided in the blower casing 6 above the cleaning casing 10.

  The nozzle 11 communicates with the water supply unit 12 via the water supply pump 13.

  The water supply unit 12 includes a tray unit 18 that stores water and a lid unit 19 that covers the top of the tray unit 18. The lid portion 19 is provided with an opening portion 20 for communicating with the water supply pump, and a water shaking prevention rib portion 21 for suppressing shaking of the accumulated water on the back surface. Water in the water supply unit 12 is supplied to the nozzle 11 by the water supply pump 13, and water is supplied from the nozzle 11 into the cleaning casing 10.

  A small hole 15 is provided at the lower end of the cleaning casing 10, and the small hole 15 can be opened and closed by a valve (not shown) provided in the vicinity of the small hole 15. The small hole 15 is formed by a valve (not shown). , The sewage scattered in the cleaning casing 10 is drained from the small holes 15 and collected in the drainage device 16.

  In the above configuration, dirt such as oil generated during cooking and indoor dust is rotated from the suction port 1 around the four sides of the rectifying plate 8 by rotating the exhaust impeller 5 by the driving means 17 (for example, a DC motor). 2 and is collected and accumulated in the oil collecting mechanism of the exhaust impeller 5. The purified air after passing through the exhaust impeller 5 is discharged from the discharge port 4 to the outside through the duct 3 by the exhaust impeller 5. In the process, oil and dust are accumulated in the exhaust impeller 5 and the oil collecting mechanism.

  In the exhaust impeller 5, oil and dust sucked into the hood 2 from the suction port 1 around the rectifying plate 8 adhere to and accumulate on the blade portion of the exhaust impeller 5, whereby the exhaust impeller 5. The flow of the inside air will change, leading to a reduction in the exhaust air volume.

  Therefore, the exhaust impeller 5 is cleaned. First, the exhaust impeller 5 is rotated by the driving means 17, and at the same time, water stored in the water supply unit 12 is pumped up by the water supply pump 13 and supplied to the nozzle 11. Then, the water in the water supply unit 12 is supplied in advance, and the water sprayed from the nozzle 11 (not shown) collides with the oil and dust accumulated in a film shape to crush and peel off the dirt film. It is removed and washed from the exhaust impeller 5 by centrifugal force due to rotation.

  The water supply unit 12 that supplies water in advance of the cleaning operation puts water into the tray unit 18 and covers the lid with the lid unit 19. When the water supply unit 12 containing water is attached to the lower side of the hood 2, the water accumulated in the tray unit 18 sways and the undulating water collides with the water sway prevention rib unit 21 provided in the lid unit 19. And it can suppress that water spills from the opening part 20 of the cover part 19, and mounting | wearing becomes unstable by making the big water shake small.

  Further, by arranging the water shaking prevention rib portion 21 around the opening portion 20, it is possible to exert the effect of suppressing shaking against the water shaking around the opening portion 20, thereby further suppressing water spillage from the opening portion 20. be able to.

  Furthermore, by arranging a plurality of water shaking prevention ribs 21 provided on the lid part 19, the collision of undulating water is increased and the shaking of the water is reduced, so that water spills from the opening 20 of the lid part 19 and is attached. Can be further suppressed from becoming unstable.

  Since the range hood according to the present invention has a structure of a water supply unit that suppresses the fluctuation of water, it is useful as a ventilation fan or the like provided with a cleaning function that requires water supply.
