  The range hood according to claim 1 of the present invention includes a thin upper hood, a lower hood provided so as to cover a lower portion of the upper hood, and a suction portion at a substantially central portion of the lower hood. An exhaust fan and a motor are provided in a space between the upper hood and the lower hood, and the lower hood and the suction port face the user from the back side toward the front side. The filter has a shape that is hollow and protrudes downward, and the bottom surface of the filter is substantially horizontal, so that the front of the filter is It has a configuration in which the opening is enlarged. Thereby, the suction area from the front of the filter is increased by increasing the opening area of the filter front opening, so that oily smoke from the cooked food is easily attracted to the front of the filter, such as oily smoke from the front of the filter. The amount of collection can be increased, and even when the collection part has a shallow structure such as a shallow range hood, the effect of preventing the collection efficiency of oily smoke and the like can be prevented.

  Moreover, you may make it the structure that the opening of the bottom face of the said filter was made small. As a result, the suction wind speed at the front, side and back of the filter is increased, so that the oil smoke and the like around the lower hood is easily drawn to the filter. Even when the collecting part has a shallow structure, oil smoke or the like can be collected from a wide range in the lower hood, and the collection efficiency can be improved.

  Moreover, you may make it the structure which eliminated the opening of the bottom face of the said filter. Thereby, the movement speed of oil smoke etc. becomes slow because oil smoke etc. from a food product hits the filter bottom without an opening, and it can make it easy to suck oil smoke etc. In addition, since there is no opening in the bottom surface of the filter, the suction wind speed at the front, side and back of the filter is increased, so that the oil smoke around the lower hood is easily attracted to the filter, so that the oil smoke is sucked in more well. It is possible to improve the collection efficiency, and to collect oil smoke and the like from a wide range in the lower hood.

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

(Embodiment 1)
As shown in FIG. 1, the range hood according to Embodiment 1 of the present invention includes a thin upper hood 1 formed in a reverse bowl shape, and waste gas, oil smoke, water vapor, odor generated during cooking in the kitchen. A lower hood 2 provided to cover the lower portion of the upper hood 1 and a suction port 3 for sucking the waste gas received near the center of the lower hood 2 are provided, and oil such as oil smoke is placed in front of the suction port 3 The filter 4 to be collected is detachably formed. Here, as an example, the filter 4 is attached and detached with a screw.

  The filter 4 is hollow and has a shape protruding downward, that is, in the direction of a cooking utensil such as a stove. The bottom surface of the filter 4 is substantially horizontal, that is, parallel to the outer flange portion of the lower hood. The front opening area on the side where the user is standing is made larger than when the bottom surface of the filter 4 is inclined.

  FIG. 2 is a perspective view showing an example of the filter 4. However, in the first embodiment, the opening area of the plurality of round holes on the bottom surface of the filter 4 is configured to be smaller than any of the other surfaces.

  In addition, it is good also as a structure which does not provide an opening in the bottom face of the filter 4, but collects oil smoke etc. on the front surface, side surface, and back surface of the filter 4.

  Further, as shown in FIG. 1, an exhaust fan 5 and a motor 6 are provided in a space between the upper hood 1 and the lower hood 2, and the waste sucked from the suction port 3 on the back surface of the upper hood 1. It consists of an adapter 7 that exhausts gas and the like. The fan 5 is constituted by a turbo fan, for example, and forms an exhaust path connecting the suction port 3 and the adapter 7.

  This is because it can be constructed at a lower cost than the sirocco fan and the fan efficiency can be improved.

  In addition, the lower hood 2 and the suction port 3 are configured to incline upward from the back side toward the front side with respect to the user, and the filter 4, the fan 5, and the motor 6 are also inclined in accordance with the inclination. .

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

  Although the fan 5 is a turbo fan, it may have other shapes such as 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 adjusting 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 and the air volume is reduced. Ensuring and noise reduction can be achieved.

  However, the adapter 7 may be configured to be attached not only to the back surface of the upper hood 1 but also to an opening (corresponding to the opening 8) such as a side surface or an upper surface.

  According to such a configuration, the amount of suction of waste gas, oil smoke, water vapor, odor, and the like from the front of the filter 4 is increased, so that oil smoke from the cooked food is easily attracted to the front surface of the filter 4. It is possible to increase the collection amount of oil smoke and the like from the front surface.

  Further, by reducing the opening area of the filter 4, the suction air speed at the front, side and back of the filter 4 is increased, and the oil smoke around the lower hood 2 is easily attracted to the filter 4. Even if the collection part such as the shallow range hood has a shallow structure, oil smoke can be collected from a wide range in the lower hood 2 and the collection efficiency can be improved.

  In addition, when an opening is not provided on the bottom surface of the filter 4 and oil smoke is collected on the front surface, side surface, and back surface of the filter 4, the oil smoke from the cooked product hits the bottom surface of the filter 4 with no opening. Thereby, the movement speed of oil smoke etc. becomes slow, it can make it easy to inhale oil smoke etc., and can improve collection efficiency further.

  The range hood according to the present invention is effective as a range hood or the like for improving the collection efficiency without using parts such as a rectifying plate even if the collection portion such as a shallow range hood has a shallow structure.
