９３１３時）。``Prior art'' In conventional cooking exhaust systems, the lower end of the duct is connected to the exhaust port of a cooking device installed indoors, and an exhaust blower is installed at the upper end of the duct. There is a blower that is smaller than the exhaust area of - and has a louver on the indoor side of the blower to adjust the suction force.
9313 hours).
又ガスレンジと前向気流誘導板との間に吸引口を設けた
下向ダクトの下端に排気ブロワ−を設けた不用排気装置
（特公昭５５−６６１号）がある。There is also an unnecessary exhaust system (Japanese Patent Publication No. 55-661) in which an exhaust blower is installed at the lower end of a downward duct with a suction port between the gas range and the forward air flow guide plate.
しカル前者では上端のブロワ−枠筐の室内側に開閉調
節ルーバを設けてあるためルーバを閉鎖しても開閉板が
漏風して気密状態にはなり得ないし漏風のためダクトの
吸引力を向上させることは困難であつた。In the former case, an opening/closing adjustment louver is provided on the indoor side of the upper blower frame casing, so even if the louver is closed, the opening/closing plate will leak air and an airtight state cannot be achieved.The air leakage improves the suction power of the duct. It was difficult to do so.

クト内に吸引し易い。 又調理器による発熱源がブロワ
−による強制対流の下限にあるため発生熱は上方に蓄熱
され上方にゆくに従つて温度の上昇を来し易い。In such an exhaust system, the lower end of the duct is connected to the exhaust valve of the cooker, so it is fine if the cooker is electric, but with gas combustion cookers such as gas ranges, flames and raw gas are sucked into the duct. Easy to do. Furthermore, since the heat source generated by the cooker is located at the lower limit of the forced convection generated by the blower, the generated heat is stored upward, and the temperature tends to rise as it moves upward.

し清潔に保持し難くダクト内引火のおそれがある。In the latter case, since the exhaust area by the suction blower is smaller than the intermediate area between the suction port and the duct, it is difficult to increase the suction force and flow velocity within the suction port and the duct, and the temperature within the duct is not lowered sufficiently and heat is likely to accumulate. Therefore, heated oil particles, smoke particles, small dust, etc. generated during cooking adhere to the inner surface of the duct, making it difficult to keep it clean and causing a risk of ignition inside the duct.

を目的とするものである。``Problems to be Solved by the Invention'' The present invention eliminates the risk of drawing flames and raw gas from a gas range into the exhaust duct, and also allows the temperature in the duct to fall, thereby removing cooking smoke from the gas range. The purpose is to discharge enough water.

た調理用排気装置によつて構成される。``Means for solving the problem'' The present invention provides a rising part at the rear of a cooking table with a gas range on the top, the rising part is in contact with a wall, and a forward airflow guide plate is provided on the same wall. , a cooking device in which the induction plate is extended above the range, an intake port is opened in the rising portion, and a forced exhaust blower is connected to the intake port via a duct, wherein the duct is connected to the intake port from the intake port. The exhaust port of the blower is formed by an airtight duct, and the exhaust area of the exhaust blower is larger than the opening area of the intake port and the intermediate area of the duct, and the intake port is opened at the upper end of the duct. and the blower is provided at the discharge end of the duct, the intake port is opened to the space between the range and the guide plate, and the blower is configured to draw suction downward into the duct. consists of an exhaust system.

力か増加する。Therefore, when the exhaust blower 8 is started, the inside of the outlet 9 of the duct 7 becomes vacuum or negative pressure, and a downward airflow toward the outlet 9 is generated in the middle part of the duct 7 and the intake port 4, which have an area smaller than the exhaust area of the outlet 9. The suction force generated and directed from the intake port 4 toward the exhaust port 10 increases.

せる。The cooking smoke 16 (FIG. 4) on the range 2 rises once into the space between the range 2 and the guide plate 6 and rises to the air intake port 4.
The air is discharged outdoors from the exhaust port 10 via the duct 7.
The airflow caused by the blower 8 is a downward forced convection, and the heat generation source by the ignited gas flame of the range 2 is placed at the upper limit of the convection, so that the airflow temperature in the duct 7 and the blower 8 decreases. In addition, since the intake port 4 is opened in the space between the range 2 and the guide plate 6, it is temporarily placed above the range 2.
The cooking smoke 16 rising into the space is sucked into the duct 7 from the intake port 4. Inside the intake port 4 and duct 7, the temperature decreases and the flow velocity increases, so heated oil particles, smoke particles, small dust, etc. generated during cooking do not adhere to the inner surface of the duct, and accidental intrusion of flames is prevented due to the drop in temperature. Disappear. 1st Embodiment A rising part 3 is formed at the rear of a cooking table 1 on which a gas range 2 is arranged or disposed on the upper surface of the cooking table 1, and an air intake port 4 is provided on the upper surface of the rising part 3 facing the side of the cooking range 2. - The upper surface of the rising portion 3 is also inclined in the same plane as the above-mentioned inclination.

た。A microwave oven 2 is attached to a wall 5 that stands upright in contact with the rear part of this rising part 3.
A cooking device is formed by providing a forward airflow guide plate 6 extending upwardly. The intake port 4 is connected to the induction plate 6 and the range 2.
The upper end of the duct 7 facing downward is connected to the intake port 4, the opening area of the intake port 4 and the middle area of the duct 7 are made the same, and the opening area of the duct 7 is formed at the terminal end of the duct 7. The exhaust area by the forced exhaust blower 8 is made larger than the opening area of the intake port 4 and the intermediate area of the duct 7. For this purpose, the outlet 9 of the duct 7 is formed to be larger than the inlet and middle of the duct 7. And from the intake port 4 to the exhaust port 10.
It is preferable to determine the dimensions of the duct 7 and the blower 8 and the strength of the blower 8 so that the air flow passage time is approximately 158 seconds or less, for example, 3 to 5 seconds. The duct 7 is formed of an airtight duct with an airtight wall from the intake port 4 to the exhaust port 10 of the blower 8, and no louvers or other air leakage gaps are provided on the indoor side of the blower 8 or other wall plates. In addition, 11 in the figure is the sky fire installed at the bottom of the range 2, 12 is the sky fire chimney, 13
is its opening, and 14 and 15 are airflow guide gratings. (Experiment example) The intake port 4, duct 7, and exhaust blower 8 shown in Figs. 5 and 6 are installed in the position shown in Fig. 2, and the gas range 2
Figure 7 shows the results of measuring the inner wall temperature of the duct 7 during normal use of the gas range 2 (gas range 2 has a calorific value of 3000 Kca1/h1 without placing a pot, etc.) on the stove. Inner wall point a, middle inner wall point b, and lower inner wall c
The temperature at the point was a>b>c and decreased as it went downward, and the temperature at point a on the upper inner wall was 60° C. or lower.

調理煙１６を充分吸引排出し得るものである。1 Effect: Since the present invention is configured as described above, the air suction force by the forced exhaust blower 8 is strengthened at the intake port 4 and the duct 7, and the cooking smoke 16 rising into the space between the range 2 and the guide plate 6 is suppressed. It can be sufficiently suctioned and discharged.

潔かつ安全に保持し得る効果がある。There is no risk that the flame or raw gas from the range 2 will be sucked into the duct 7 from the intake port 4, and since the gas range 2 is the source of sewage generation at the upper limit of the forced convection caused by the duct 7 and the blower 8, the lower limit of the blower On the 8 side, the temperature tends to fall, which is highly secure in terms of fire prevention. That is, the exhaust area by the blower 8 is larger than the intermediate area between the intake port 4 and the duct 7, and since the duct 7 is airtight as described above and has no air leakage, the suction force and flow velocity inside the intake port 4 and the duct 7 are small. As mentioned above, the temperature can be lowered sufficiently and there is no heat accumulation, so there is no risk of heated oil particles, smoke particles, small dust, etc. generated during cooking adhering to the inner surface of the duct, and the ignition inside the duct is extinguished. This has the effect of keeping the inside of the duct 7 clean and safe.
