Description

  The present invention relates to a range hood that is installed in a kitchen and exhausts air mixed with oil, dust, or the like from a stove or the like.

  Conventionally, this type of range hood is known in which a cylindrical filter is provided on the outer periphery of a fan in a fan casing of a blower (see, for example, Patent Document 1).

JP 2009-103454 A

  In such a conventional range hood, it is only necessary to reduce the area of the filter ventilation hole in order to improve the removal of oil, but the exhaust efficiency is lowered because the ventilation area to be exhausted is reduced accordingly. It had the problem that.

  Therefore, the present invention solves the above-described conventional problems, and an object thereof is to provide a range hood capable of improving oil removal efficiency without reducing exhaust efficiency.

  In order to achieve this object, the present invention provides a hood having a suction port and a discharge port above a kitchen appliance and a plurality of blades coupled to an electric motor in the vicinity of the discharge port of the hood. A fan is provided inside, and an oil collecting part for attaching oil to the inside of the centrifugal fan is provided, thereby achieving the intended purpose.

  According to the present invention, a hood having a suction port and a discharge port above a kitchen appliance, and a centrifugal fan having a plurality of blades coupled to an electric motor in the vicinity of the discharge port of the hood are provided. In addition, since the oil collecting part for attaching oil to the inside of the centrifugal fan is provided, the exhaust air is applied to the oil collecting part and the oil is attached to the oil collecting part. Therefore, the effect that the oil removal efficiency can be improved without reducing the exhaust efficiency can be obtained.

Les Njifudo of the present invention includes: a hood having an inlet and an outlet above the kitchen appliance, in the vicinity of the outlet of the hood, which includes a centrifugal fan having a plurality of blades coupled to the motor inside And it has the structure that the oil collection part which makes oil adhere to the inside of the said centrifugal fan was provided. As a result, the exhaust air is applied to the oil collecting part and the oil adheres to the oil collecting part, so that the oil removal efficiency can be improved without reducing the exhaust efficiency.

  Moreover, you may make it the structure which formed the ring which has the some recessed part which inserts a braid | blade on the outer side through the holding | maintenance part in the up-down direction. As a result, the exhaust air is applied to the ring and the oil adheres to the ring, so that the oil can be easily attached to the ring and the oil removal efficiency can be improved without reducing the exhaust efficiency. There is an effect.

  The hood may be provided with a nozzle for supplying water to a casing surrounding the centrifugal fan, a water supply means for supplying water to the nozzle, and a means for collecting sewage scattered in the casing. . As a result, the ring to which the oil is attached is rotated in the water supplied into the casing, so that the oil removal efficiency can be improved while further improving the exhaust efficiency.

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

(Embodiment 1)
As shown in FIG. 1, a flat rectangular (rectangular) suction box plate 2 having a cavity 27 is provided above a kitchen appliance 1 such as a stove. A suction port 3 is provided on the front side of the suction box plate 2, that is, the side on which the cook stands, for sucking steam, smoke, or ambient air generated when cooking from a pan or pan that is a kitchen appliance 1. Then, the exhaust box plate 5 is connected to the upper side, that is, the ceiling 6 side so as to communicate with a cavity 27 provided above the suction port 3 on the back side of the suction box plate 2, that is, the side of the chamber wall 4 facing the side where the cook stands. A hood 8 having a discharge port 7 for discharging to the chamber wall 4 is attached to the chamber wall 4 and installed. A sirocco fan or turbo that has a plurality of blades 12 coupled to an electric motor 10 composed of a motor 9 that rotates by direct current or alternating current, near a discharge port 7 of the exhaust box plate 5 of the hood 8 via a shaft 11. This is a range hood in which a centrifugal fan 14 that sucks air 13 from the center of a fan or the like from the kitchen appliance 1 or the like and exhausts the air 13 to the outer periphery is provided inside the exhaust box plate 5 of the hood 8. And it is the structure which inserted and fitted the oil collection part 15 which makes the air 13 containing oil contact the inside of the centrifugal fan 14, ie, the space which sucks in air 13, and attaches oil.

  With this configuration, the exhaust air that is the air 13 is brought into contact with the oil collecting unit 15, the oil is attached to the oil collecting unit 15, and after contact, the oil collecting unit 15 is exhausted. As a result, the oil removal efficiency can be improved without reducing the exhaust efficiency.

  Then, the oil collecting part will be described in detail. As shown in FIG. 2, a plurality of recesses 16 into which the blades 12 (see FIG. 1) of the centrifugal fan 14 (see FIG. 1) are fitted on the outside, that is, the outer peripheral side. As shown in FIG. 3, the ring 17 having the structure is formed by stacking in a vertical direction via a plurality of holding portions 18 over a certain distance.

  The fixed distance may be any distance as long as the exhaust air 13 flows within the target pressure loss, and the ring 17 may be divided.

  With this configuration, the concave portion of the ring 17 is fitted along the blade 12 in the central space of the centrifugal fan 14, and as a result, the oil collecting portion 15 is installed on the inner surface of the centrifugal fan 14, and the motor 9 shown in FIG. Then, the air 13 is sucked from the suction port 3, and the air 13 which is exhaust air is applied to the ring 17 to adhere to the ring 17 as shown in FIG. Since it flows in the circumferential direction and is discharged from the blade 12 of the centrifugal fan 14, passes through the discharge port 7, and is discharged to the outside through the duct 28, the oil contained in the air 13 is easily removed from the air 13. Since it can adhere to the ring in the process of passing and the area through which the exhausted air 13 passes is larger than that of the conventional holes such as a plurality of punch holes, the oil efficiency can be reduced without lowering the exhaust efficiency. Can be improved efficiently exhibits the remarkable effect that.

  Further, as shown in FIG. 1, a nozzle 20 that supplies water to a casing 19 that surrounds the centrifugal fan 14, and a water storage unit 21 that stores water that supplies water to the nozzle 20, on the exhaust box plate 5 in the hood 8. And a water supply means 25 composed of a pump 22 and a tube 23 connecting the nozzle 22 or the water storage part 21 from the pump 22, a water discharge hole 24 and its water discharge hole below the casing 19 for collecting sewage scattered in the casing 19. In this configuration, a water discharge storage unit 26 for collecting sewage through 24 is provided.

  With this configuration, the centrifugal fan 14 provided with the ring 17 is rotated in the water stored in the casing 19 below the casing 19 supplied with the ring 17 to which the oil contained in the air 13 adheres. Therefore, the oil adhering to the blade 12 and the ring 17 of the centrifugal fan 14 is removed, and the exhaust of the air 13 due to the oil adhering is prevented, thereby improving the exhaust efficiency and improving the oil removal efficiency. There is a remarkable effect that it is possible.

  The structure that removes dirt by the force of water to be sprayed and centrifugal force can be applied to a ventilation device that collects dirt with a filter and is installed in a place where it is difficult to maintain and maintain the filter.
