This is treated air from which contaminants such as oil smoke and media have been removed by the grease filter (25) and rear filter (26), and even if it flows along a wall surface, it will not pollute the wall surface excessively.

This processing air is blown out with speed and pressure applied to it, so it is sent to the existing exhaust system (18a) which is operating without being diffused on the way. The existing exhaust device (18a) takes in the air directly from the forced smoke exhaust device (15) that is sent to the vicinity of its suction port and exhausts it to the outside of the room. That is, in the heating cooking device of this embodiment, the heating cooking section can be easily installed by simply adjusting the positional relationship with the existing exhaust device (18a>) without having to perform duct construction or major exhaust construction for smoke exhaust. The polluted air containing oil smoke, smoke, steam, etc. generated during the use of (1) is generated and successively sucked in and sent to the existing exhaust device (18a) such as a ventilation fan, damaging the exhaust function of the existing exhaust device <18a). In conjunction with this, it is possible to effectively exhaust the air outside. In other words, it is easy to install, and by cooperating with existing exhaust devices such as ventilation fans <18a) that are widely installed in the kitchen, without wasting their functions, orderly ventilation of the kitchen can be realized. In particular, since polluted air is sucked near the place where it is generated, insufficient polluted air can be treated with a small air volume, and stains on the walls around the cooking section of the kitchen can be significantly reduced. Furthermore, since the exhaust is not directly vented outdoors, there is an advantage that, for example, in the case of a tempura fire, the spread of fire can be prevented by taking fire prevention measures in the forced smoke exhaust system (15). Furthermore, the back wall (36
) are all within the height range of the cooking work surface, making maintenance such as cleaning easy.
