【Example】
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0010]
(Example 1)
FIG. 1 is an external perspective view illustrating a high-frequency heating device according to a first embodiment of the present invention.
[0011]
FIG. 2 is an external perspective view of a main part showing an opening / closing mechanism of the apparatus.
[0012]
In FIG. 1, an opening 16 is provided in the front of a heating chamber 15 for storing an object to be heated, and a door 17 which is in contact with the opening and closes the heating chamber is openably and closably mounted on the front of the heating chamber. I have. An operation panel 6 having a control board 11 and an opening / closing lever 9 is fixed beside the door.
[0013]
In FIG. 2, a holding portion 7 and an inverted L-shaped side regulating protrusion 8 are formed on the back surface of the operation panel 6 by molding. By inserting the shaft portion 9a of the opening / closing lever into the hole provided in the holding portion 7, the opening / closing lever 9 is fixed to the back surface of the operation panel 6 so as to be rotatable around the hole of the holding portion 7, and the rotational force is reduced. The information is transmitted to the door fixed to the front of the heating chamber, and the door is opened and closed.
[0014]
FIG. 3 is a cross-sectional view of a main part when the open / close lever is attached, and FIG. 4 is a cross-sectional view of the main part when the open / close lever is pushed up.
[0015]
In FIG. 3, the opening / closing lever 9 attached to the back surface of the operation panel 6 is such that the overhang 9b enters the space between the side regulating protrusion 8 and the holding portion 7 and the overhang 9b hits the side regulating protrusion 8. This prevents the shaft portion 9a of the opening / closing lever from coming out of the holding portion 7.
[0016]
In FIG. 4, when the open / close button 10 is pressed, a force is applied to the open / close lever 9 in the rotation direction about the shaft 9a, and the door is opened. In this case, a control board including a display unit 13 in which the position regulating protrusion 9c on the upper surface of the opening / closing lever displays the cooking time and the like, an operation switch 14 for inputting the cooking time and the operation, a relay 12 for controlling the operation of the high-frequency heating device, and the like. 11, the movement in the rotation direction is restricted, and the overhanging portion 9 b interferes with the side regulating protrusion 8, so that the opening / closing lever 9 does not come off the operation panel 6.
[0017]
When the opening / closing lever 9 is attached to or detached from the operation panel 6, if the control board 11 is not fixed, there is no restriction on the rotation direction of the opening / closing lever 9, so that the overhanging portion 9b and the side regulation are not provided. Attachment and removal can be easily performed at positions where the projections 8 do not interfere.
[0018]
In this embodiment, the control board is constituted by a plurality of control boards. However, the control board may be constituted by a single control board by changing the shape of the projecting portion of the opening / closing lever and the fixing position of the control board.
[0019]
【The invention's effect】
As is clear from the above description, according to the present invention, the following effects can be obtained.
[0020]
A heating chamber for storing and heating the object to be heated, a door attached to the opening of the heating chamber to open and close the object to be heated, an open / close lever for opening and closing the door, and cooking time are displayed. A control board having a display portion to be opened, and an operation panel formed with a holding portion for holding the opening / closing lever, wherein the side portion of the opening / closing lever comes into contact with a protruding portion of the opening / closing lever in the vicinity of the holding portion on the back side of the operation panel. By providing a regulating protrusion, the position regulating protrusion on the upper surface of the opening / closing lever comes into contact with the control board and regulates the operation in the rotating direction, so that the operation when inserting the opening / closing lever into the holding portion is easy, and the opening / closing lever is prevented from coming off. In addition, there is an effect that a stable operation of the opening / closing lever can be performed.
