Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to an oven toaster used in ordinary households.

[0002]

2. Description of the Related Art Conventionally, an oven toaster of this kind has a configuration disclosed in Japanese Patent Application Laid-Open No. 3-241237. Hereinafter, the above-mentioned star will be described with reference to FIGS. Inner housing 52 forming cooking cabinet 51
An upper heater 53 and a lower heater 54 are suspended on the side wall of the upper heater. A grill 55 is provided between the upper heater 53 and the lower heater 54. On the front surface of the main body 58, a door 56 whose central part, which opens and closes the front opening of the inner housing 52, is made of a transparent glass 57 is provided. A hinge 59 is provided on the cooking cabinet 51 side of the door 56 so as to detachably lock the front side of the grill 55.

Reference numeral 60 denotes a shaft penetrating through an arc-shaped hole 61 provided on the left and right side walls of the inner casing 51.
Is urged rearward by a spring 62. The grill 55 is detachably hooked to the hinge 59 at the front, and is detachably latched to the shaft 60 at the back of the grill 55.

With the above structure, when the door 56 is opened and closed, the grill 55 moves back and forth by the hinge 59,
The shaft 60 locked at the rear of the grill 55 also has an arc-shaped hole 6.
It is moved back and forth within 1. Also, the hinge portion 59 and the shaft 60
The grill 55 can be removed by removing the locking portions of the grill 55 locked to the respective portions.

[0005]

However, in such a conventional structure, when the grill 55 is removed, the door 56 is supported only by the rotating shaft of the door 56, and the mounting strength of the door 56 to the main body is reduced. When the door 56 is opened and closed in this state, a load is applied to the rotating shaft, and the rotating shaft may be deformed or damaged, and the supporting strength of the door 56 is reduced.

When attaching the grill 55, first, the locking portion of the grill 55 to the shaft 60 is locked to the shaft 60, then the grill 55 is pulled forward, and the shaft 60 is inserted into an arc-shaped hole. It is necessary to move the inside of the portion 61 and hook the front portion of the grill 55 on the hinge portion 59 in a state where the grill 55 is pulled.

Further, the shape of the grill 55 becomes complicated due to the locking portion to the shaft 60 and the L-shaped bending at the rear to prevent the food from dropping, and the wire 55 has an end face of the wire. However, there is a disadvantage that cleaning of the grill 55 is difficult.

The present invention solves such a conventional problem, and has a strong and easy-to-use, safe, and inexpensive oven-attaching / removing structure for the attaching / detaching operation of the grill. It is intended to provide a star.
