た。2. Description of the Related Art A range hood fan which merely sucks waste gas and discharges it to the outside of a room requires a wide and deep hood to ensure discharge. Nevertheless, it was inevitable that waste gas would enter the room. In addition, the range hood is entirely occupied by the range hood, and there is a problem in terms of effective use of the indoor space.

不満足な状況であった。[0003] In order to avoid the drawbacks mentioned above, it has heretofore been proposed to create an air curtain around the range. However, in the examples so far, a long distance is required between the blower and the outlet in order to create an airflow having a thin and wide cross section suitable for an air curtain, and only a thick range hood is eventually obtained. could not. Therefore, it was still unsatisfactory in terms of effective use of the indoor space.

するようにすることである。The problem to be solved is that the vertical height of the range hood fan can be reduced so that a space for installing a cabinet or the like can be secured above the range hood fan, and waste gas or the like can be kept indoors. This is to ensure that the water is discharged outside the room without intrusion.

ある。According to the present invention, a centrifugal fan as a main exhaust blower is mounted on a hood by using a centrifugal fan so that its rotation axis is vertical. The height of the top and bottom is made thin, and an air curtain is formed on the front of the hood by a once-through fan, so that waste gas, etc. does not come out of the range as much as possible outside the air curtain, and comes out near the ceiling. Waste gas and the like staying in the air are suctioned as air curtain air, blown to a range, and discharged outside the room by a centrifugal fan for exhaust. The use of the cross-flow fan only on the front side is the invention of claim 1, and in addition, the cross-flow fan is disposed at the left, right, or the back or a combination thereof as necessary,
The second aspect of the present invention provides an air curtain.

The hood main body 1 is fixed to a wall surface (not shown) of the building by a fixing bracket 2. Waste gas and the like generated around the range pass through the filter 3, from the inside of the multi-blade impeller 6 of the centrifugal fan driven by the bell mouth 7 and the motor 8, that is, to the inside of the scroll 5.
Further, the air passes through the duct adapter 9 and the shutter 10 and is discharged outside through the duct 11. The illumination lamp 4 illuminates the periphery of the range. The curtain plate 12 is a blindfold for a space including the centrifugal fan. Once-through fan 13 driven by motor 14
By sucking air at the upper part of the front of the range and blowing it to the lower part, an air curtain is formed to prevent waste gas from flowing out of the range into the room. Collect again. By doing so, the waste gas can be reliably discharged outside the room. If the outside air is introduced into the room at a position slightly away from the periphery of the range in order to avoid negative pressure in the room air, the discharge of waste gas around the range to the outside can be more reliably performed. Become.

In contrast to the first embodiment, a cross-flow fan 13 is disposed on the front surface of the hood, a cross-flow fan 15 is disposed on the left side, and a cross-flow fan 17 is disposed on the right side for the air curtain. Each flow-through fan is driven by a motor 14, 16, 18, respectively. The back side is typically a wall and no air curtain is required. However, if there is a special case where the range is in the center of the room, it is also possible to place a once-through fan for the air curtain at the place where the illumination lamp 4 is usually located. It is also possible to arrange the lamp 4 and the once-through fan side by side.
