Description

[Detailed Description of the Invention] [Object of the Invention] The present invention provides a roaster that can be used for both yakiniku and hot pot.
This invention relates to an exhaust device for a roaster that stops exhaust gas suction from the roaster body when cooking in a pot or when the roaster is not in operation, and prevents the resulting imbalance of suction forces between the roasters.

Conventionally, in a roaster that can be used for both yakiniku and hot pot cooking, the intake hole in the top plate is closed with a rectifier plate to allow hot air from the gas burner etc. to hit the pot when cooking in a hot pot. Although the system was designed to prevent hot air from being sucked in, it required a rectifying plate and had the disadvantage of requiring time and effort to remove.

In addition, although one main fan was used to suck in the exhaust gas from multiple roasters, if the suction of one or more roasters is stopped while cooking in a pot or when the roasters are not in operation, other This has the disadvantage that it affects the suction force of the roaster, causing it to become unbalanced, resulting in excessive suction, making it impossible to cook grilled meat, etc. sufficiently.

Also, the inside of the store is air conditioned and ventilated,
When exhaust gas is not sucked during hot pot cooking or when it is sucked without cooking, the air conditioning load increases as air conditioned air is sucked in. On the other hand, depending on the hot pot cooking or the number of diners, the number of roasters that can be operated and sucked is limited. This had the disadvantage that ventilation was not sufficient.

U ("' Section - The present invention provides a roaster that can be used for both yakiniku and hot pot.
By stopping exhaust gas suction from the roaster body when cooking in a pot or when not in operation, and sucking air from the suction pipe, it is possible to balance the suction power between each roaster when one or more roasters stop suctioning. It is an object of the present invention to provide an exhaust device for a roaster which prevents the collapse of the roaster.
