DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oven toaster, and more particularly to an oven toaster which moves in conjunction with opening and closing of a door of a heating chamber.
The present invention relates to a detachable grid mounting structure.

[0002]

2. Description of the Related Art Conventionally, as this kind of oven toaster, there is, for example, one shown in Japanese Patent Application Laid-Open No. 3-241237. These conventional oven toasters have a configuration in which the grille is movable in the front-rear direction in conjunction with opening and closing of the door, and both ends of a sliding shaft that moves in the front-rear direction are respectively provided on both side walls of the heating chamber. And the grill is placed on and engaged with the sliding shaft, so that the grill can be taken in and out in conjunction with the opening and closing operation of the door.

[0003] On the left and right sides of such a grill, holding members which can be easily and detachably engaged with the sliding shaft are formed.

[0004]

However, in the above-described oven toaster, when the grill is placed in the heating chamber, first, a holding member formed behind the grill is engaged with the sliding shaft. However, since the mounting position of the holding member is at the rear end of the grill, and the sliding shaft is also pulled by the spring member and located deep inside the heating chamber,
It is very difficult to accurately engage the holding member with the sliding shaft. If both the holding members on the left and right sides of the grill cannot be engaged with the sliding shaft, one of the holding members provided on the left and right is used. There was a problem that only one of the meshes was engaged with the sliding shaft and the grill was installed diagonally. Further, in order to solve such a problem, if the holding member is formed at only one position at the center of the grill, the problem of the grill being installed obliquely is solved, but the force acting on the sliding shaft is eliminated. Is concentrated at one point, there is a possibility that the sliding shaft is bent from that part.

[0005] The present invention has been made in view of the above problems, and has as its object to provide an oven toaster in which a grill can be easily installed.
