[0006]

Therefore, when the sirocco fan 10 is started, the air in the empty box 9 is sucked, and further, through the horizontal and downward pipes 7 and 5, from the cooking suction port 3 to the pan 14 on the gas range 2 or the like. The generated steam, the combustion gas generated from the gas range 2 and the like are sucked into the exhaust port 1 of the fan 10.
2 can be discharged outdoors.

In this state, the air in the expanded diameter portion 9'is merged a'with the passing air flow a in the empty box 9 and the negative pressure in the empty box 9 is forced by the suction force of the sirocco fan 10 to cause the lateral pipe 7 and The suction force in the downward pipe 5 is strengthened, the suction port 3 is smaller than the lateral width of the gas range 2, and the suction port 3 is divided by the plurality of heat conduction plates 13 to promote suction.

When the cooking oil in the frying pan 14 on the gas stove 2 burns, the flame enters the suction port 3 and the combustion heat is generated by a plurality of heat conduction plates 13 or the small-diameter pipe 13 in FIG. 9 (a). It conducts to the'and the perforated plate 13 "to reduce the temperature and burn out. The heat conduction plate 13, the circular hole 3", the small diameter tube 13 'and the perforated plate 13 ", the downward suction box 4, the downward and lateral pipes 5 , 7, 7 ', 7 ",
A stainless steel plate or the like is used for the empty box 9 or the like.

[0009]

EXAMPLE A cooking table 1 is provided along a partition wall 15 of a cooking chamber, and a gas range 2 is provided above the cooking table 1. A suction port 3 is provided between the rear part of the gas stove 2 and the partition wall 15, and the opening 3'is inclined downward toward the front (Fig. 2).

The suction port 3 can be opened laterally on the inner surface of the partition wall 15 (FIG. 3).
It can be opened in the front wall of 0 (FIGS. 4 and 5). These suction ports 3 are horizontally oriented rectangular openings 3 ′ or circular holes 3 ″, the width of which is approximately ½ of the area width of the gas range 2.
A downward suction box 4 is connected to the suction port 3, a downward pipe 5 is hung at the lower end of the suction box 4, and the lower end of the downward pipe 5 extends along the floor surface 6. Installed horizontal pipe 7
Are connected with a bellows bent pipe 8. Further, it can be directly connected to the downward pipe 5 (FIGS. 4, 5, and 6).

The downward pipe 5 or the horizontal pipe 7 is connected to one end of an empty box 9 having a diameter larger than that of the pipe 5 or 7, and the suction port 11 of the other end (side surface) is connected to the suction port 11 of the sirocco fan 10. ', And the suction port 11 at the other end of the empty box 9 and the suction port 11' of the sirocco fan 10 are connected by a pipe 7 '' having the same diameter as that of the horizontal pipe 7.

In FIG. 8, the cooking smoke suction port 3 is a circular hole 3 ", and a plurality of small-diameter tubes 30 for heat conduction which are in contact with the inner circumference of the circular hole 3" are arranged, and the front end of the suction port 3 is arranged. For heat conduction perforated plate 3
1 is detachably arranged. The perforated plate 31 may be made of steel.

A pipe 7'having the same diameter as that of the pipe 7 is also connected to the outlet 12 of the sirocco fan 10, the pipe 7'is opened to the outdoor wall 16, and a rain shield 17 and a wind direction plate 18 are provided. In FIG. 8, a water tank 9 ″ is formed at the bottom of the empty box 9, a water level holding device 25 is provided by an S-shaped pipe 24, and an oil absorbing sheet 26 is floated above the water level to absorb the oil that flows down and collect it. A sprinkling pipe 26 ′ is provided on the side surface of the pipe 5 and sprayed from the nozzle 27 into the pipe 5.

As described above, the operation of the empty box 9 causes a vacuum portion in the enlarged portion 9'due to the expansion of the diameter and the suction of the sirocco fan 10 to lower the internal air pressure, whereby the suction force of the pipe 7 is forced. Along with that, the width of the cooking smoke suction port 3 can be reduced, and moreover, the heat conduction plate 13 or the small-diameter pipe 13 'is divided into a plurality of ports, so that the suction port 3 is suctioned in an orderly manner so that there is no vortex flow and the suction is smooth. Can be done.

Reference numeral 19 in the figure indicates Gotoku, 21 in FIG.
Is an opening / closing lid for removing oil, 22 is a tightening bolt between the suction port 3 and the downward suction box 4, 23 is a long hole for adjusting the length between the suction port 3 and the suction box 4, and 28 in FIG. 9 is the suction port 3 It is a projection that is detachably fitted to the small pipe 29 inside.

[0016]

As described above, according to the present invention, since the suction area of the suction port is reduced and divided into a plurality of ports as described above, the cooking smoke is divided and suctioned, and the suction resistance is not divided into swirl and is suctioned in order. The cooking smoke becomes small and is easily sucked and is sucked by the downward and / or sideways pipes having a relatively small diameter, and the suction force is forced by a simple device by forcing negative pressure in the empty box.
In addition, there is an effect that a safe and quiet exhaust device that is easy to burn is obtained.

Further, the oil absorbing sheet floating in the water tank at the bottom of the empty box can absorb the oil scattered during cooking and replace the sheet to prevent the oil from flowing out.
