Description

  The present invention relates to a range hood.

  A conventional range hood that collects oily smoke generated during cooking and exhausts it to the outside is composed of an upper hood and a lower hood. Here, the upper hood has an inverted bowl shape with the lower surface opened, and a discharge port is formed on the side surface or the like. The lower hood covers the lower surface opening of the upper hood (see, for example, Patent Document 1).

  Hereinafter, it demonstrates, referring FIG. 2 which is sectional drawing of the conventional range hood. As shown in FIG. 2, the range hood includes an upper hood 102, a partition plate 106, a suction port 107, and a lower hood 108. Here, the upper hood 102 has an inverted bowl shape having an open lower surface, and a discharge port 101 is formed on a side surface or the like. The partition plate 106 partitions the inside of the upper hood 102 into an electrical component chamber 103 where electrical components are provided and a blower chamber 105 where the blower 104 is provided. The suction port 107 communicates with the blower 104. The lower hood 108 covers the lower surface opening of the upper hood 102.

  The operation of the range hood configured as described above will be described. When the blower 104 rotates, oily smoke or the like generated during cooking in the kitchen sucked from the suction port 107 is carried to the discharge port 101 through the lower hood 108, the suction port 107, the blower 104, and the blower chamber 105, and outdoors. Exhausted.

  In such a conventional range hood, in the case of a shallow structure such as a shallow range hood, the oil smoke is not sucked from the collection part on the near side of the user and overflows, and the oil smoke collecting efficiency is reduced. There was a problem.

Japanese Patent No. 3329693

  The range hood of the present invention includes an upper hood formed in an inverted bowl shape and a lower hood having an opening surface that covers the lower side of the upper hood. The range hood has a suction port formed at the center of the lower hood, and an exhaust fan and a motor are provided in a space between the upper hood and the lower hood. The opening surface is divided into a front opening surface on the near side close to the user and a back opening surface on the back side far from the user. When the area surrounded by the line segment extending in the vertical direction from the outer periphery of the front opening surface and the outer periphery of the rear opening surface and the lower hood is the front collecting portion and the rear collecting portion, respectively, the front side The volume of the collection part is made larger than the volume of the back side collection part.

  The oil smoke sucked from the suction port does not overflow from the near side collecting part because the volume of the near side collecting part is larger than the volume of the far side collecting part, and the oil smoke collecting efficiency does not decrease.

FIG. 1 is a side view of a range hood according to an embodiment of the present invention. FIG. 2 is a cross-sectional view of a conventional range hood.

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

(Embodiment)
FIG. 1 is a side view of a range hood according to an embodiment of the present invention. As shown in FIG. 1, the range hood according to the embodiment of the present invention includes an upper hood 1 and a lower hood 2. A suction port 3 is provided at a substantially central portion of the lower hood 2, and waste gas and the like are sucked from the suction port 3. A filter 4 for collecting oil of oily smoke is detachably provided in front of the suction port 3. Here, as an example, the filter 4 is attached and detached with a screw.

  The upper hood 1 is formed in a thin inverted bowl shape. The lower hood 2 that receives waste gas, oily smoke, water vapor, odor, etc. generated during cooking in the kitchen covers the lower side of the upper hood 1 and has an opening surface 2a. Further, the area surrounded by the lower hood 2 is an oil smoke collecting portion 11 to be exhausted.

  The opening surface 2 a is divided into a front opening surface 2 b on the near side 13 close to the user 12 and a back opening surface 2 c on the back side 14 far from the user 12. The area surrounded by the line segment extending in the vertical direction 15 from the outer periphery of the front opening surface 2b and the outer periphery of the rear opening surface 2c and the lower hood 2 are respectively the front collecting portion 11a and the rear collecting portion 11b. In this case, the volume of the near-side collection part 11a is made larger than the volume of the back-side collection part 11b.

  Instead of the filter 4, for example, a wire mesh guard may be used to prevent injury.

  An exhaust fan 5 and a motor 6 are provided in a space 10 between the upper hood 1 and the lower hood 2. On the back surface of the upper hood 1, an adapter 7 for exhausting waste gas or the like sucked from the suction port 3 is provided. The fan 5 is a turbo fan, for example. An exhaust path connecting the suction port 3 and the adapter 7 is formed. Turbofans are cheaper and more efficient than sirocco fans.

  In addition, the lower hood 2 and the suction port 3 are configured to incline upward from the back side 14 toward the near side 13 with respect to the user 12. That is, the lower hood 2 has a convex cone shape with respect to the upper hood 1. And the filter 4, the fan 5, and the motor 6 are arrange | positioned along the inclined surface 2d which goes to the near side 13 from the back | inner side 14 which forms a cone shape.

  The tilt angle may be any angle as long as the fan 5 and the motor 6 are tilted to the height between the bottom surface of the lower hood 2 and the top surface of the upper hood 1.

  The fan 5 is a turbo fan, but may be a sirocco fan with a casing. The adapter 7 is attached to the opening 8 on the back surface of the upper hood 1. By matching the inclination angle of the fan 5 and the opening angle of the shutter 9 of the adapter 7, the resistance of the exhaust path is reduced, the air volume is ensured, and the noise is reduced. However, the adapter 7 may be attached not only to the back surface of the upper hood 1 but also to an opening such as a side surface or an upper surface.

  In such a range hood, the oil smoke from the front of the user 12 is sucked into the suction port 3 along the lower hood 2 inclined upward from the back side 14 toward the front side 13 with respect to the user 12. . Therefore, even if the collection part 11 of the inclined part of the lower hood 2 becomes deep and the collection part 11 such as a shallow range hood has a shallow structure, a decrease in the collection efficiency of oil smoke is prevented.

  The fan 5 and the motor 6 are inclined upward from the back side 14 toward the front side 13 with respect to the user 12. And since the oil smoke from the front of the user 12 is sucked into the fan 5 inclined upward from the back side 14 toward the near side 13 with respect to the user 12, the suction surface of the fan 5 faces diagonally forward and downward, The position of the suction port 3 moves forward. Therefore, even if the collection unit 11 such as the shallow range hood has a shallow structure, the oil smoke collection efficiency is further prevented from being lowered.

  Moreover, as shown in FIG. 1, the oil collection part 16 is provided in the lowest position 2e of the inclined surface 2d. Since the oil adhering to the lower hood 2 and the upper hood 1 flows into the oil collecting portion 16, the oil recovery efficiency is improved and the periphery of the range hood is not soiled by the oil.

  INDUSTRIAL APPLICABILITY The present invention is useful as a range hood or the like that improves the collection efficiency without using parts such as a rectifying plate even if the collection part such as a shallow range hood has a shallow structure.
