Description

  The present invention relates to a range hood, and more particularly to a range hood characterized by an internal hood.

  Conventionally, in a range hood that is provided above a cooker and collects water vapor or oily smoke generated by cooking, an inner hood that covers the inner surface of the hood is provided in order to improve cleanability and design. Yes. (For example, Patent Document 1)

  However, in such a conventional inner surface hood, the direction of air flow changes immediately after the water vapor or smoke sucked from the suction gap formed by the gap between the current plate and the inner surface hood is changed. Collide with. If it does so, water vapor | steam and oil smoke will adhere to the inner surface hood of the suction gap vicinity, and when a range hood is used for a long time, the adhering water | moisture content and oil and fat may flow on the surface of an inner surface hood, and may be dripped on a cooker. Such a phenomenon often occurs in a thin range hood with a thin hood, since the air flow changes from the suction gap at a steep angle as the hood is thinner.

  In order to avoid such a phenomenon, the moisture and oil / fat that adheres by flowing the entire inner surface hood in one direction to flow in one direction, and the moisture and oil / fat that has flowed by the protruding piece (bead) provided on the inner surface hood Was dripped positively on the upper surface of the current plate. In addition, by providing a protruding piece (bead) on the inner surface hood surface downstream of the air flow from the peripheral edge of the current plate, moisture and oil and fat can be dripped onto the cooker along the inner surface hood. It was dripped positively on the upper surface of the current plate while preventing this.

JP 2011-94850 A

  However, in the case of a range hood with a thin hood, it is difficult to incline the entire inner hood due to space requirements, and providing a protruding piece (bead) on the inner hood disturbs the air flow. Therefore, the oil smoke collection performance, which is the basic performance of the range hood, was reduced. Moreover, when the protruding piece was provided on the inner hood, the workability was poor and the appearance was also poor.

  Therefore, the present invention has been made in view of the above problems, and the object of the present invention can be applied to a range hood having a thin hood, from the gap between the inner hood and the current plate. By suppressing disturbance of the flow of air sucked from the formed suction gap, it does not reduce the collection performance of oil smoke, and further suppresses the adhesion of moisture and oil and fat to the inner hood, even if temporarily attached, An object of the present invention is to provide a range hood having an aesthetic appearance, which is provided with an inner hood for preventing moisture and fats and oils from dripping onto a cooking device.

In order to solve the above-described problem, a range hood having an opening to a blower, an inner surface hood that covers the inner surface of the hood, and a rectifying plate that forms a suction gap by a gap between the inner surface hood and the peripheral portion, The inner surface hood has a parallel surface portion that is substantially parallel to the upper surface of the opposing rectifying plate and an upper inclined surface portion that extends continuously from the parallel surface portion and inclines upward toward the outer edge of the inner surface hood around the opening. And a lower inclined surface portion continuously extending from the upper inclined surface portion and inclined downward toward the outer edge of the inner surface hood, and the lower end of the lower inclined surface portion forms a suction gap together with the peripheral edge portion of the current plate. In the horizontal direction, a range hood is provided in which the peripheral edge portion is located between a first boundary between the parallel surface portion and the upper inclined surface portion and a second boundary between the upper inclined surface portion and the lower inclined surface portion.
According to this, it can also be applied to a range hood with a thin hood, and it can catch oil smoke by suppressing the disturbance of the flow of air sucked from the suction gap formed by the gap between the inner hood and the current plate. It is possible to provide a range hood that does not deteriorate the collection performance, and further suppresses the adhesion of moisture and fats and oils to the inner surface hood and prevents the moisture and fats and oils from dripping onto the cooker.

Furthermore, the rectifying plate may be provided with a rising portion at the peripheral portion, and the shortest distance from the upper end of the rising portion to the second boundary may be larger than the shortest distance from the upper end to the first boundary.
According to this, the amount of the air flow sucked from the suction gap formed by the gap between the inner surface hood and the rectifying plate reduces the amount of contact with or collides with the lower inclined surface portion, and conversely, contacts with the upper inclined surface portion. Therefore, the amount of moisture and oil / fat on the lower inclined surface portion can be suppressed and the adhesion to the upper inclined surface portion can be promoted.

Further, the upper surface of the rectifying plate positioned vertically below the first boundary may be an oil receiving portion.
According to this, it can serve as an oil receiver and a baffle plate.

Further, the upper inclined surface portion and the lower inclined surface portion may be provided only on the front side and / or the side surface side of the range hood.
According to this, it can provide only in the part to which a water | moisture content and fats and oils are easy to adhere.

  As described above, according to the present invention, it can be applied to a range hood with a thin hood, and the turbulence of the air sucked from the suction gap formed by the gap between the inner surface hood and the current plate is It is possible to provide a range hood with good aesthetics that suppresses the adhesion of moisture and fats and oils to the inner surface hood and prevents the moisture and fats and oils from dripping onto the cooking device.

The lower end 17C of the surface portion 13C forms a suction gap 5C together with the peripheral edge portion 21 of the rectifying plate 20. In the horizontal direction, the peripheral edge portion 21 includes the first boundary 14C between the parallel surface portion 11C and the upper inclined surface portion 12C, and the upper inclined surface portion. It is located between 12C and the 2nd boundary 15C of the downward sloping surface part 13C.

  According to this, the design of the inner surface of the hood can be improved, and the hood can be applied to a range hood with a thin hood, and suction is performed from the suction gap 5C formed by the gap between the inner surface hood 10C and the rectifying plate 20. By suppressing the turbulence of the flow of the air, it is possible to suppress the adhesion of moisture and fats and oils to the inner surface hood 10C, and to prevent the moisture and fats and oils from dripping onto the cooker.

  The shortest distance (A) from the upper end of the rising portion 22 to the second boundary 15C is preferably larger than the shortest distance (B) from the upper end to the first boundary 14C. According to this, it is possible to reduce the amount of the air flow sucked from the suction gap 5C in contact with or collide with the downward inclined surface portion 13C, and to reduce the amount of moisture and oil / fat on the downward inclined surface portion 13C. Can be reduced. For this reason, the suction | inhalation of the air from 5 C of suction gaps can concentrate the water | moisture content and fats and oils which adsorb | suck around 5 C of suction gaps to the upper inclined surface part 12C. Therefore, it is possible to effectively prevent moisture and oil and fat from dripping from the inner surface hood 10C to the cooking device by guiding the moisture and oil and fat adhering to the upper inclined surface portion 12C to the back surface side of the current plate 20 by the inclination. be able to.
