Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating and cooking apparatus in which a door of a microwave oven or the like opens sideways, and upper hinges for rotatably holding the door are attached to the heating chamber front plate and the heating chamber upper plate. .

[0002]

2. Description of the Related Art A conventional cooking device of this type is shown in FIG.
There was something like that shown in FIG.

In FIG. 5, 1 is a cooking apparatus main body, 2 is a heating chamber for accommodating food, 3 is a heating chamber front plate which forms the front surface of the heating chamber 2, and 4 is a heating chamber which forms the upper surface of the heating chamber 2. A plate 5, an opening provided for putting food into the heating chamber front plate 3, 6 a door for opening and closing the opening 5, 7 a lower hinge for holding the door 6 rotatably, 8 rotating the door 6 An upper hinge that holds freely. In FIG. 6, upper hinges 8 are burring holes 9 for screw tightening provided in the heating chamber upper plate 4 and the heating chamber front plate 3 from above the heating chamber front plate 3 and the heating chamber upper plate 4.
Screw holes 12 and 1 provided in the upper hinge 8
It is fastened to screws 3 and 14 with screws 15, 16 and 17.

[0004]

However, in the above-mentioned conventional structure, since the front plate of the heating chamber and the upper plate of the heating chamber are usually made of thin sheet metal, the upper hinge 8 is replaced by the front plate 3 of the heating chamber and the upper plate of the heating chamber. When tightening with screws 15 and 16 to 4 and tightening with strong torque, it will be screwed up, so it is necessary to adjust the torque of the electric screwdriver etc. so that it does not become screwed up, and if it is tightened with a torque that does not screw up, it will be a door When force is applied to 6, the upper hinge 8 moves due to the clearance between the hinge screw holes 12 and 13 and the screws 15 and 16, and the door 6 moves accordingly. Therefore, screw 17 is added and the door 6
Although the upper hinge 8 was attached so as not to move, it took time to fix the upper hinge 8 and there was a problem that workability was poor.

An object of the present invention is to solve the above-mentioned conventional problems, and an object thereof is to provide a heating and cooking apparatus for fixing the hinge to the heating chamber upper plate and the heating chamber front plate without adding screws.

[0006]

In order to solve the above-mentioned conventional problems, in the heating and cooking apparatus of the present invention, the upper hinge is inserted into a hole provided above the front surface of the front plate of the heating chamber, and one of the heating chamber and the heating chamber is inserted. A screw is tightened from the upper flange side of the front plate to the upper hinge, and the other is fixed to the upper plate of the heating chamber with a screw.

As a result, the screw can be fastened to the upper hinge with a strong torque, so that the upper hinge and the front plate of the heating chamber can be firmly attached and the upper hinge can be fixed without adding a screw, which shortens the assembly time and improves workability. Can be better.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION The invention according to claim 1 is a heating chamber for containing food, a heating chamber front plate forming a heating chamber front surface, a heating chamber upper plate forming a heating chamber upper surface, and a heating chamber. It consists of an opening provided for putting food in the front plate, a door that closes the opening, and an upper hinge that rotatably holds the door, and the upper hinge is provided above the front of the heating chamber front plate. The screw is inserted into the upper hole of the heating chamber front plate, and one screw is fastened to the upper hinge from the upper flange side of the heating chamber front plate, and the other is fixed to the heating chamber upper plate with a screw. Since the upper hinge and the front plate of the heating chamber are strongly attached, the upper hinge can be fixed without adding screws,
Assembly time can be shortened and workability can be improved.

The invention as defined in claim 2 is particularly characterized by claim 1.
By fixing the upper hinge of the heating and cooking apparatus described above to the upper hinge from the heating chamber upper plate side, even if the screw is tightened with a strong torque, the screw does not become stupid and the front plate of the heating chamber and the upper plate of the heating chamber. The screws can be tightened with the same torque, the torque of the electric screwdriver, etc. can be adjusted in the same way, and workability can be improved.
