[Prior technology] The heating equipment such as an electromagnetic conditioner or a gas stove in the kitchen is used for conditioning, for example, the oil used for the conditioning becomes oil fume and evaporates, and the water vapor of the conditioning material rises with the moisture of the conditioning material. . The exhaust fume and the like diffuse it into the kitchen, which not only pollutes the walls or furniture, but also the air in the kitchen. Therefore, in the past, various exhaust hoods installed on the conditioner of the kitchen have been #collected by the fan installed in the exhaust hood to collect exhaust gas and discharge it outside the house. On the other hand, if you look at homes in recent years, you'll often see collective houses built with concrete. The tightness of each room has become very high, and the kitchen with a range hood has also become tighter. to. Even in Haifengxingnan's kitchen, even if, 丨 will operate the fume exhaust as described by 冋 科 述 because it can not supply the air commensurate with the exhaust gas, and as a result, sufficient exhaustion cannot be performed. Also consider playing. ® is used to guide outdoor air, but in the winter, it becomes a cold air, and the purposeful exhaust hood in the room is not fully used. As a result, all the long-term treatments of the females have become the work fluid that pollutes the room, and oil fume is attached to the walls or furniture.

O: \ 87 \ 87I65 DOC -8- Ϊ232920 In recent years, due to the high-rise housing complexes, high-rise apartments have been installed in about 20 meters or more. Due to the influence of wind, sufficient air supply may not be possible. The first reason is because the wind from the window side is difficult to enter, and it is difficult to directly take in outdoor air. The second reason is because it is more high-rise, because the negative C outdoor occurs on the window side. The introduction of air becomes difficult. That is, the outside of the room on the opposite side to the windward side, because the negative wind caused by the passage of wind L, even if the vent is opened on the wall, it is not easy to take in outdoor air from there. In addition, in this type of range hood, regardless of the season and the state of the window, at: Week: Later, even if the fan is stopped immediately, the exhaust including the oil fume is also raised by the conditioner, and the exhaust will also pollute the kitchen Inside the air or walls. ^ The applicant hereby proposed in Japanese Patent No. 3131731, etc., the proposal fully mentions two, the exhaust function of the exhaust hood for gas function, and further promote the idea of the national patent No. 313 1731, about how to make The gas can also be carried out on its own.
