BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooking device such as an oven toaster.

[0002]

2. Description of the Related Art In the oven toaster disclosed in Japanese Utility Model Publication No. 4-132522, the door opens to the front side of the toaster body. The grill, which is a food shelf, works in conjunction with the above door,
When the door is opened, it moves forward so that food can be easily taken in and out.

[0003]

In such an oven toaster, it is necessary to secure a space for an opening door on the front side of the toaster body, which limits the installation location of the toaster.

When the cooked food is taken out from the grill, the door opened on the front side is touched. Then, since the door is hot after cooking, there is a risk of getting burned.

Further, in the case of such a cooker, when the inner surface of the door and the wall surface of the heating chamber are contaminated by oil or the like scattered from the food during cooking, the window glass can be detached and removed for cleaning. There are also doors that can be detached, but the structure is complicated, so it is difficult to attach and detach, and there is a problem that maintenance is difficult. Further, since the opening area of the front opening of the main body is relatively small, there is a problem that the inside of the heating chamber cannot be easily cleaned.

The present invention simplifies the construction and improves the degree of freedom of installation place by making it unnecessary to secure an open space for the door, and eliminates the risk of being burned when taking out food.
An object of the present invention is to provide a cooker in which the heating chamber and the door can be easily cleaned after cooking.

[0007]

A cooker according to the present invention has a heating chamber having a front opening having a side arc shape, a food rack arranged in the heating chamber and moving back and forth, and placed on the food rack. Heating means for heating food, a side arcuate door that opens and closes the front opening, and a side plate formed on the side of the door,
A door shaft formed near the front opening and the arc center of the door in the side plate, and rotatably supporting the door so that the door can open and close the front opening, and a gear mounted on the door shaft. And a rod that is formed on the side of the food shelf and supports the food shelf so that it can move back and forth, and that is attached to this rod and meshes with the gear, moves rearward when the door is closed, and opens the door. Sometimes it has a rack that moves forward.

Furthermore, a spring is provided near the center of the front-back movement range of the rack and pulls the rack.

Further, the door shaft is detachably mounted on the side plate, and a groove is formed integrally with each of the abutting portions of the tip end of the door shaft and the door shaft of the gear in a detachable manner. .

[0010]

When the door is opened, the door rotates upward about the door shaft so as to slide along the front opening and overlaps the wall surface of the cooker body. At this time, the gear rotates together with the door shaft in the same direction, the rack meshing with the gear moves forward, and the food rack connected to the rack via the rod also moves forward.

When closed, the door reverses its movement and rotates downward about the door axis so that it slides along the front opening. At this time, the rack engaged with the gear moves rearward, and the food rack also moves rearward.

Then, in order to reduce the impact when the door is opened and closed, the rack is pulled by a spring near the center of its front-rear movement range and always tries to return to the center.

Since the door shaft is detachably attached to the side plate, the door can be removed only by removing the door shaft from the side plate. Further, the rotational movement of the door shaft is surely transmitted to the gear via the groove.
