2. Description of the Related Art Combustion gas emitted from a stove during cooking,
Range hoods are used to exhaust smoke, smell, etc. In recent years, cooking rooms are becoming more airtight. Oxygen deficiency may occur in the room due to consumption. Further, in the case where exhaust is performed by a range hood in a cooking room where heating and cooling are performed, there is an unreasonable possibility that even the warm or cold air in the room is discharged to the outside together with the stove exhaust. To solve such a problem,
Conventionally, Japanese Utility Model Laid-Open No. 57-101823 and Japanese Utility Model Laid-Open No. 5
Various proposals for introducing outside air into a room at the same time as exhaustion by a range hood have been made in Japanese Patent Application Laid-Open Nos. 4-98055 and 58-142630.

In the above-mentioned apparatus, an air supply fan is provided on a stove or a stove base together with a range hood. However, since an air supply duct of the air supply fan and an exhaust duct of the range hood are completely separated, The air supply and exhaust duct work had to be done separately, which made the work very cumbersome. On the other hand, the stove table to which the stove is attached is often configured so that the top surface is flush with the top surface of the sink etc. installed on both sides, forming a sink top. In order to install a stove or an air supply fan, the top plate of the stove must be installed separately from the upper surfaces of the adjacent sinks. Therefore, the structure is unsuitable when a high-quality sink top is formed by using a single top plate such as artificial marble on the upper surface of the sink top.

An object of the present invention is to provide a cooking apparatus having an air supply function including a stove and a range hood, in which air supply and exhaust can be easily performed, and without separating a top plate of a sink top. To provide a function that can be installed.

It can be easily connected to the air supply path by a flexible duct. Therefore, as compared with the conventional one in which the exhaust duct of the range hood and the duct of the air supply mechanism provided on the stove are separately provided, the labor for construction can be greatly reduced. In addition, since the stove is installed in a state of being dropped into the opening established in the top plate of the stove base, the stove can be installed without separating the top plate portion of the stove base from the top plate such as the sink on both sides Become like According to this, the top plate of the sink top can be constituted by a single plate, and the appearance and quality of the sink top can be improved. Since the above-mentioned air blowing holes are provided so as to surround the stove, the air required for combustion of the stove can be effectively supplied from around the stove, and at the same time, the air blown out from the air blowing holes By the air curtain formed by the above, the diffusion of the exhaust gas rising from the stove can be suppressed, and the collection efficiency by the range can be improved. In addition, when the air supply passage formed around the outer periphery of the stove body is divided into a front edge section, a rear edge section, and left and right side edge sections, the solenoid valve for adjusting the air supply amount provided in each distribution pipe is adjusted. By doing so, it is possible to adjust the amount of air blown out from the air blowout holes for each section. For example, when the cook is standing in front of the stove, the amount of air blown out from the leading edge section of the air supply passage can be reduced so that the cooking operation is not hindered.
