Description

  The present invention relates to a range hood installed in a kitchen of a house.

  Generally, in a residential kitchen, a range hood is provided above a cooking device provided in the kitchen, and polluted air containing oily smoke, combustion gas, and the like generated during cooking is discharged to the outdoors.

  However, if a range hood is simply provided above the cooking device, a large amount of contaminated air is generated and diffused, or until the contaminated air rises from the vicinity of the cooking device and reaches the range hood, for example, cooking. If there is a case where it spreads under the influence of air turbulence caused by the action of shaking cooking utensils such as frying pans or woks during work, or the action of people crossing, all contaminated air will be removed from the hood of the range hood. In some cases, the trapped surface could not be collected and a part of the sample stayed in the vicinity of the ceiling surface, causing the ceiling surface to become dirty.

  In order to increase the collection efficiency of contaminated air in the range hood, the hood portion may be brought close to the heating cooker, but the installation height of the hood portion of the range hood is about 800 mm or more away from the upper surface of the kitchen countertop. There is a limit stipulated in the Fire Service Act of height, and inevitably contaminated air that leaks without being collected by the hood part is generated.

  Therefore, for example, as disclosed in Patent Literature 1 and Patent Literature 2, it is possible to further collect contaminated air that remains in the vicinity of the ceiling without being collected by the hood portion above the hood portion of the range hood. A range hood has been proposed.

  However, contaminated air that reaches the ceiling without being collected by the hood portion of the range hood spreads in all directions along the ceiling surface, so even when using the above range hood, keep away from the range hood. It is difficult to collect the contaminated air that has been diffused, and there is a possibility that the contaminated air remains in the vicinity of the ceiling surface.

  In particular, when applied to open kitchens such as island-type kitchens and peninsula-type kitchens, which have been increasing in recent years, the three- or four-way open areas around the range hood are close, and the walls that restrict the spread of polluted air are close. Therefore, there is a problem that the collection efficiency of contaminated air is further deteriorated.

  Further, when the hood portion of the range hood is provided so as to hang from the ceiling surface of the kitchen, there is a problem that the feeling of opening of the kitchen space is impaired.

  Accordingly, in order to solve the above problems, the present invention aims to provide a range hood that can reliably prevent the retention of contaminated air near the ceiling surface of the kitchen and can be an open kitchen space. And

  In order to solve the above problems, the range hood 1 of the present invention captures the thin hood 12 directly attached or embedded in the ceiling 5 of the kitchen 2 and the contaminated air rising from the kitchen 4 installed in the kitchen 2, and A rectifying plate 25 that leads to the suction port 21a of the hood 12, and the rectifying plate 25 has an area that is equal to or larger than the area of the counter top 6 of the kitchen 4 and covers the upper side of the counter top 6. It is arranged in.

  Specifically, the rectifying plate 25 has an area equal to or larger than the area of the countertop 6 of the island type kitchen 4 or the peninsula type kitchen located immediately below. Further, the rectifying plate 25 constitutes substantially the entire ceiling surface of the kitchen 2.

  According to the range hood of the present invention, since the thin hood is directly attached or embedded in the ceiling of the kitchen, the openness of the kitchen space can be enhanced as compared with the conventional case where the hood is suspended from the ceiling. it can. In addition, since the upper part of the countertop is covered with a baffle plate that has a larger area than the countertop of the kitchen, the collection area for capturing the contaminated air rising from the kitchen can be greatly expanded. It is possible to increase the collection efficiency and reliably prevent stagnation of contaminated air near the ceiling surface.

  Furthermore, by increasing the collection efficiency of contaminated air in this way, it can be effectively applied to open kitchens with a sense of openness such as island type kitchens and peninsula type kitchens.

  Also, the direction of the polluted air rising from the kitchen can be obtained by configuring the entire ceiling surface of the kitchen with a baffle plate and making the entire ceiling surface, which is the final point of the polluted air, the trapping surface for the polluted air. Even if it diffuses, it can be reliably caught by the current plate which is the ceiling surface and can be reliably sucked into the thin hood from the suction port, and the collection efficiency of contaminated air can be further enhanced.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. As shown in FIG. 1, the range hood 1 according to one embodiment of the present invention is attached to the ceiling portion 5 of the kitchen 2 immediately above the island kitchen 4 arranged in an island shape without contacting the wall surface 3 of the kitchen 2. It has been. The island-type kitchen 4 includes a substantially square countertop 6, and a cooking device 7, a sink 8, and the like are attached to the countertop 6.

  The range hood 1 includes a fan case 11 that houses a fan 10 and a thin hood 12 that is attached to the lower portion of the fan case 11. The fan case 11 passes through the ceiling plate 13 of the ceiling portion 5 and is disposed in the ceiling back space 14. An exhaust duct 15 disposed in the ceiling space 14 is connected to the fan case 11.

  The thin hood 12 includes a substantially rectangular upper surface plate portion 20, a substantially rectangular lower surface plate portion 21 disposed substantially parallel to the upper surface plate portion 20, and the upper surface plate portion 20 and the lower surface plate portion 21. It is formed in a hollow box shape having a substantially square shape in plan view by side plate portions 22... Connecting the edge portions. And by fixing the upper surface board part 20 to the lower surface of the ceiling board 13, the thin food | hood 12 is distribute | arranged to the kitchen space in the state directly attached to the ceiling part 5. FIG.

  The lower surface plate portion 21 of the thin hood 12 is formed with first suction ports 21a, and the side surface plate portions 22 are formed with second suction ports 22a. A filter (not shown) is detachably attached to the first suction port 21a and the second suction port 22a.

  The lower surface plate portion 21 of the thin hood 12 captures contaminated air including oil smoke and combustion gas that rises from the vicinity of the heating cooker 7 of the island-type kitchen 4, and the first suction port 21 a. A substantially rectangular current plate 25 that leads to the mouth 22a is attached.

  As shown in FIG. 2, the current plate 25 has an area that is equal to or larger than the area of the countertop 6 of the island kitchen 4, and is arranged substantially horizontally so as to cover the upper side of the countertop 6. In addition, since the rising speed of polluted air becomes quick when using the gas stove compared with the case where the electric stove is used as the heating cooker 7, the area of the rectifying plate 25 assumes the case where the gas stove is used. I am trying to set it. The bottom surface of the current plate 25 is coated with a finishing material made of a photocatalyst having an antifouling function and an antibacterial function.

  In the above configuration, when cooking is started in the heating cooker 7 of the island type kitchen 4 and contaminated air containing oil smoke, combustion gas, etc. from the vicinity of the heating cooker 7 rises, the rectification of the range hood 1 covering the upper side of the counter top 6 The plate 25 is reached. The polluted air trapped by the current plate 25 moves in the horizontal direction along the current plate 25 and is sucked into the thin hood 12 from the first suction ports 21a located outside the current plate 25. The At this time, even if the contaminated air leaks to the side of the thin hood 12 without being sucked at the first suction port 21a,..., The contaminated air is further outside the first suction port 21a,. 2 is sucked into the thin hood 12 from the suction port 22a. The contaminated air sucked into the thin hood 12 is discharged to the outside through the exhaust duct 15.

  As described above, since the thin hood 12 of the range hood 1 is directly attached to the ceiling portion 5 of the kitchen 2 above the island-type kitchen 4, an open kitchen space can be provided. Moreover, since the upper part of the countertop 6 is covered by the rectifying plate 25 having a larger area than the countertop 6, the collection area for capturing the contaminated air rising from the vicinity of the heating cooker 7 provided on the countertop 6 is greatly expanded. As a result, the collection efficiency of the contaminated air can be increased, and the retention of the contaminated air in the vicinity of the ceiling surface can be reliably prevented.

  3 and 4 show a range hood according to another embodiment. In the range hood 1, the thin hood 12 is arranged so as to cover the ceiling portion 5 of the kitchen 2, and the area of the rectifying plate 25 is substantially equal to the ceiling area (floor area) of the kitchen 2. The board 25 constitutes substantially the entire ceiling surface of the kitchen 2. That is, substantially the entire ceiling surface, which is the final arrival point of the contaminated air, serves as a contaminated air collection surface. Note that the range hood 1 according to this embodiment may be constructed on site in place of the ceiling board 13 in constructing the kitchen space. Other configurations are the same as those of the embodiment shown in FIGS. 1 and 2 except that the thin suction hood 12 is not formed with the second suction ports 22a.

  Thereby, no matter which direction the contaminated air rising from the vicinity of the heating cooker 7 is diffused, it is surely captured by the rectifying plate 25 that is the ceiling surface and reliably sucked into the thin hood 12 from the first suction port 21a. This can further increase the collection efficiency of the contaminated air.

  FIG. 5 shows a range hood according to another embodiment. The range hood 1 is arranged in the ceiling space 14 with the thin hood 12 embedded in the ceiling 5 of the kitchen 2, and the rectifying plate 25 is arranged substantially flush with the ceiling plate 13. Yes. In this case, the feeling of opening of the kitchen space can be further enhanced. Other configurations are the same as those of the embodiment shown in FIGS. 1 and 2 except that the thin hood 12 is not formed with the second suction ports 22a.

  FIG. 6 shows a range hood according to still another embodiment. In this range hood 1, a thin hood 12 embedded in the ceiling portion 5 of the kitchen 2 is arranged so as to cover the top of the kitchen 2 instead of the ceiling plate, and the area of the rectifying plate 25 is the ceiling area of the kitchen 2. It is substantially equal to (floor area), and the rectifying plate 25 constitutes substantially the entire ceiling surface of the kitchen 2. That is, substantially the entire ceiling surface, which is the final arrival point of the contaminated air, serves as a contaminated air collection surface. In this case, the feeling of opening the kitchen space can be further increased, and the collection efficiency of contaminated air can be further increased. Other configurations are the same as those of the embodiment shown in FIG.

  The present invention is not limited to the above embodiment, and it is needless to say that many modifications and changes can be made to the above embodiment within the scope of the present invention. For example, the range hood of the present invention is not only provided for an island type kitchen, but also provided for other open kitchens such as a peninsula type kitchen, or a general kitchen such as an I type or an L type. You may provide corresponding to.

  Moreover, in the said embodiment, although the baffle plate was attached to the lower surface board part of a thin hood, you may make it function a lower surface board part itself as a baffle plate. Furthermore, you may attach a lighting fixture to a thin food | hood, and may use it as a sink light in an open kitchen without a hanging door.
