In addition, in the case of household cookware, there is also a merit that cooking cooked in the kitchen can be brought to the dining room together with the cookware.

By the way, in such a conventional mobile cooker, exhaust of smoke or heat generated from the cooker poses a problem.

In order to solve such a problem, a separate exhaust means may be provided at the moving destination, or it can be used as a ventilation fan in the normal state, and when the cooking utensil is moved, an expandable duct is attached to this ventilation fan. It is conceivable to attach a hood that the user has to exhaust air.

However, in the case of providing the former separate exhaust means, there is a problem that the cost increases and the destination is fixed, which is not practical.

In the latter case, the retractable hood must be attached to and detached from the ventilation fan every time the cooking utensil is moved.
Such work is very complicated, and when not in use,
In addition to the need for the retractable duct and the storage space for the hood, the retractable duct is mounted in a direction orthogonal to the ventilation fan installed on the wall, so that the base of the duct is bent at a right angle. When the cooking utensil is moved to a proper position, the bending angle of the duct becomes large, resulting in poor durability.

The present invention was devised in view of the current situation, and an object thereof is to provide an exhaust facility to a moving destination of a mobile cooking appliance without attaching and detaching an expandable duct and a hood each time they are used. It is an object of the present invention to provide a range hood device that can be easily moved and can improve the durability by reducing the bending angle of the duct accompanying the movement of the cooking utensil.
