[0008] According to this, oil smoke and gas generated in the roaster chamber are discharged from the exhaust port through the exhaust duct. At this time, the end of the exhaust duct is opened at the suction part of the range hood fan, so that even if the distance between the range hood fan and the range is up and down, oil smoke and gas etc. It is guided to the suction portion of the range hood fan without diffusing into the kitchen, and is sucked and discharged by the range hood fan.

When the range hood fan is provided with a grease filter in the hood main body, the end portion of the exhaust duct may be located upstream of the grease filter and connected to the hood main body. (Invention of claim 2). According to this, the grease filter removes oils and fats from the exhaust air from the roaster chamber, and then the air can be exhausted through the hood body of the range hood fan, thereby contaminating the fan blades and the inner surface of the hood body. Can be prevented as much as possible. Further, since the distal end of the exhaust duct is connected to the hood main body, the effect of preventing the diffusion of oil smoke and combustion gas becomes higher.

[0010] Incidentally, in the above-mentioned exhaust duct, there is a situation where burning components such as oils and fats in oil smoke and dust adhere to the inner surface of the exhaust duct with use for a long time, and if a flame enters the exhaust duct. Then, there is a possibility that the flame propagates to the tip. However, if a flame propagation preventing structure in which the cross-sectional area of the base end of the exhaust port or the exhaust duct is smaller than the cross-sectional area of the roaster chamber (the invention of claim 3), even if a flame is generated in the roaster chamber, The flame can be prevented from propagating in the exhaust duct toward the front end.

Further, the wall of the kitchen located near the exhaust duct can be made nonflammable (the invention of claim 5). According to this, even if the exhaust duct becomes hot, safety can be maintained. Can be increased.

The range hood fan is generally configured so that the intensity of the ventilation air volume can be adjusted. However, the exhaust air from the roaster compartment is affected by the ventilation air volume of the range hood fan. That means
Due to the difference in the ventilation air volume of the range hood fan, a situation arises in which the heating state of the roaster room varies. Therefore, an exhaust fan for forcibly exhausting the air in the roaster chamber can be provided in the exhaust port portion or inside the exhaust duct (the invention of claim 6). According to this, since the exhaust air from the roaster chamber is controlled by the exhaust fan, for example, by setting the exhaust air volume of the exhaust fan to a predetermined air volume, it is not affected by the ventilation air volume of the range hood fan. It becomes possible.

[0013] Further, the exhaust fan can be configured to be driven in conjunction with the heating operation of the roaster chamber (the invention of claim 7). According to this, when the roaster chamber is used, it is ensured. The exhaust fan can be driven, and a separate operation by the user for operating the exhaust fan can be eliminated.

Further, in the present embodiment, a filter 30 for shutting off the flame is provided in the connection portion 29a of the exhaust duct 29. This filter 30
Is made of a metal mesh as shown in FIG.

Next, the operation of the above configuration will be described. For example, when grilled fish is cooked in the roaster chamber 17, oil smoke, combustion gas, and the like are generated. The oil smoke and gas are discharged from the exhaust port 28 to the outside of the range 13, guided to the suction portion of the range hood fan 14 through an exhaust duct 29 connected to the hood body 23, and sucked by the range hood fan 14, The air is discharged outside through the outdoor discharge duct 27.

Thus, even if the distance between the range hood fan 14 and the range 13 is vertically different, oil smoke and gas in the roaster chamber 17 are discharged without diffusing into the kitchen 11. It is. Further, since the exhaust gas from the roaster chamber 17 is passed through the grease filter 26 in the range hood fan 14, the grease filter 26 removes oils and fats and dust, and thus the blades of the fan device 25 and the inner surface of the hood body 23.

However, in this embodiment, a flame propagation preventing structure is employed in which the cross-sectional area A of the connecting portion 29a at the base end of the exhaust duct 29 is smaller than the cross-sectional area B of the roaster chamber 17. Even if a flame is generated in the roaster chamber 17, the flame can be prevented from propagating to the duct main portion 29b in the exhaust duct 29 beforehand. Moreover, in the present embodiment, since the metal mesh filter 30 is provided in the connecting portion 29a, the propagation of the flame is more reliably prevented.

As described above, according to the present embodiment, the exhaust duct 29 connecting the roaster chamber 17 and the range hood fan 14 is provided. Unlike the one that may be diffused into the kitchen 1, oil smoke, gas, and the like coming out of the roaster room 17 of the range 13 can be effectively exhausted by the range hood fan 14. As a result, it is possible to prevent the user from feeling uncomfortable due to the diffusion of oily smoke and gas, and to prevent the smell and dirt from adhering to the wall 11a of the kitchen 11 or the like.

In the present embodiment, the exhaust duct 29
Since a flame propagation preventing structure is provided at the base end portion of the roaster chamber 17, even if a flame is generated in the roaster chamber 17, it is possible to prevent the flame from propagating in the exhaust duct 29, and to obtain an advantage of excellent safety.
