Description

[Detailed Description of the Invention] The present invention relates to the structure of attaching a door plate to the front surface of a high-frequency heating device.

If a metal rod, etc. is accidentally inserted into the heating chamber through the peephole on the heating chamber door while food is being heated using a high-frequency heating device, microwaves propagate along the surface of the metal rod and leak to the outside. There is a risk of

Therefore, by providing a door plate made of transparent or translucent resin or glass on the door surface of the heating chamber, the above-mentioned danger is prevented and the overall design of the high-frequency heating device is improved. .

The door valance plate has conventionally been fixed to the door surface by screwing, welding, or using a picture frame.

That is, door valances made of resin have been fixed by screwing or welding, and door valances made of glass have been fixed with a picture frame type frame.

However, resin door panels have a large coefficient of thermal expansion, so
Since the door valance expands and contracts due to temperature changes caused by the use of a high-frequency heating device, conventional fixing by screwing or welding may deform the door valance, giving it an unsightly appearance.

In addition, especially when the door panel is fixed by welding, it is very difficult to replace the door panel if it is damaged or to remove it for cleaning.

Also, when fixing a glass door pelmet with a picture frame, the frame and glass part cannot be securely fixed due to variations in dimensions, and a special frame must be prepared, which increases costs. was there.

The present invention provides a door plate and a holding plate between the door body and the handle, and presses the holding plate against the door plate using an elastic member such as a spring inserted into the recesses at both ends of the handle. It is designed to be attached to the surface of the door, and its purpose is to use an elastic member to absorb the expansion and contraction of the door valance due to temperature changes, and to facilitate the attachment and detachment of the door valance to the door body.

Next, embodiments of the present invention will be described in detail based on the drawings.

Fig. 1 is a front perspective view of the high-frequency heating device, Fig. 2 is a partial sectional view of the door portion of the high-frequency heating device, Fig. 3 is a sectional view of the door plate attachment section, and Fig. 4 is a sectional view of the door body and This is an explanatory diagram of the method for attaching the door valance plate to the main body of the high-frequency heating device.

In FIG. 1, a door 2 is attached to the front of a high-frequency heating device 1 so as to be openable and closable, and a handle 3 is attached to the door 2.

Furthermore, the high-frequency heating device 1 is equipped with a microwave oscillation device inside, and is configured to supply microwaves into the heating chamber to perform heating.

Next, as shown in FIG. 2, the door body 4 of the door 2 is provided with a shielding plate 5 on the heating chamber 6 side, in which a large number of holes 5a are perforated to prevent microwave leakage.

In addition, in order to protect the shielding plate 5 from dirt and damage, the shielding plate 5 is
is covered with a transparent plate 7.

A door decoration plate 8 formed to cover the door body 4 is attached to the front surface of the door body 4.

To attach the door valance plate 8, as shown in an enlarged view in FIG. Installation of JLL
The OA and door valance plate 8 are attached by inserting them into the holes 8a and fixing the handle 3 to the door body 4 with screws 11.

That is, the door decorative plate 8 is attached to the door body 4 by being pressed against the door body 4 via the presser plate 10 by the repulsive force of the spring 9 fitted into the handle 3 fixed to the door body 4.

Next, the installation of the door 2 to the high frequency heating device main body is carried out in the fourth step.
As shown in the figure, a door hinge shaft 12 is fixed to the main body of the high-frequency heating device (Fig.
This is done by inserting a hole 2a provided in the door body 4 and the door valance plate 8 into a hole 2a (only a is shown).

Although the present invention has the above-described configuration, when the food in the heating chamber is heated by microwaves, if the door plate is made of resin, the door plate receives heat from the food. Although thermal expansion occurs, in the present invention, the door pelmet is not fixed to the door body but is attached elastically by an elastic member, so no excessive force is generated, and therefore the door pelmet does not deform. .

Furthermore, even if the door fascia is made of glass, according to the present invention, it can be installed without rattling, unlike conventional methods, even if there are variations in component dimensions. It is advantageous.

Furthermore, according to the present invention, it is easier to attach and detach the door valance to the door body than in the past, so there is also the effect that assembly and repair are easier.
