Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a high-frequency heating device that dielectrically heats an object to be heated housed in a heating chamber using high-frequency waves.

Conventional structure and its problems As shown in FIG. 3, the structure of a conventional microwave oven, which is a high-frequency heating device, is provided with a heating chamber 2 in which the object to be heated is housed in a main body 1, and an opening of this heating chamber 2. A door 3 is provided in the section so as to be openable and closable. Reference numeral 8 denotes an opening peripheral plate with which the inner plate 9 of n3 makes surface contact when the door 3 is closed, and is configured to prevent high frequency waves from leaking from inside the heating chamber 2.

Then, the upper end of the bent opening peripheral plate 8, the sash 1o and the sash cover 11 are fixed with screws 21, thereby forming the front surface of the main body 1.

In the high-frequency heating device having such a configuration, a gap is created at the joint 22 between the opening peripheral plate 8 and the sash 1o.
Not only was it undesirable in appearance, but it was also difficult to clean and use if food particles got into it.

If the distance between the screws 210 for attaching the trench cover 10 and the cover 11 to the opening peripheral plate 8 is too wide, the seat 1
Since the gap between the joint portion 22 between the opening peripheral plate 8 and the opening peripheral plate 8 is large, it is necessary to tighten the joints at appropriate intervals, resulting in poor assembly workability.

There was a drawback in that when the satchel 10 and the cover 11 were opened and tightened to the peripheral plate 8 with the screws 21, the joint surfaces were curved and radio waves were likely to leak.

OBJECTS OF THE INVENTION The present invention solves the above-mentioned conventional drawbacks, and aims to provide a high-frequency heating device that is easy to assemble, easy to use, and does not leak radio waves.

Structure of the Invention In order to achieve the above object, the high frequency heating device of the present invention has the following features:
A peripheral plate of the opening of the heating chamber, which comes into surface contact with the inner plate of the door when the door is closed, is extended to constitute at least one side of a granite provided facing the periphery of the door,
The locking part of the satshu cover is provided at the end of the sash cover, making it easy to work with the sash cover.Furthermore, since the sash cover and the opening peripheral plate are integrated, it prevents radio wave leakage due to deformation of the sash. This has the effect that it is possible to obtain a high-frequency heating device that is easy to prevent, easy to clean, and convenient to use.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

In FIG. 1, reference numeral 1 denotes a main body of a high-frequency heating device, and a heating chamber 2 for accommodating an object to be heated is provided within this main body 1. 3 is a door provided at the opening of the heating chamber 2 so as to be openable and closable;
is an operation panel provided on the front of the main body 1, and this operation panel 4 has a timer knob 6 for setting the heating time. Cooking start button 6. Seven display lamps are provided to indicate the cooking time.

In Fig. 2, reference numeral 8 denotes an opening peripheral plate with which the inner plate 9 of the door 3 makes surface contact when the door 3 is closed. A locking portion 12 of the sash cover 11 is provided at the end. One end of this Satsushi force bar 11 is connected to the Sanonku 10.
The other end is locked to the opening peripheral plate 8.

The gap between the Zanyu 10 and the door 3 is for opening and closing the door 3, and although it is better to be narrow from the viewpoint of preventing radio wave leakage, the gap is set to 2 to 4 mm in consideration of mass production. The dimension H between the engagement part between the edge plate 8 of the opening/sash 10 and the force bar 11 can be set as appropriate within the range of 6 mm to the thickness of the door 3, taking into consideration the standards regarding radio wave leakage and the appearance. good.

In this way, according to the high-frequency heating device of this embodiment, the opening peripheral plate 8 of the heating chamber 2 is bent and extended outward to form one side of the sash 10, and the sash force bar 11 is attached to the end of the sash 1o. By providing the locking part 12, it is extremely easy to attach the sash cover 11 to the sash cover 10, and since the other end of the sash force bar 11 is latched to the opening peripheral plate 8, the sash cover 11 can be held in a stable state. It can be easily taken advantage of.

Furthermore, by integrally forming one side of the opening peripheral plate 8 with the extension of the opening peripheral plate 8, it is easy to clean even if food particles adhere to the opening peripheral plate 8, making it easier to use and improving the assembly process. This has the effect of being able to provide a high frequency heating device that is simple and free from radio wave leakage.

Effects of the Invention As described above, according to the present invention, the following effects can be obtained.

(1) By integrally forming at least one side of the sash with the extension of the opening peripheral plate of the heating chamber, the number of assembly steps can be reduced.

(2) Even if food particles adhere to the opening peripheral plate, since the opening peripheral plate and the sash are integrally constructed, it is easy to clean and maintain a clean state.

(3) By providing the locking portion of the locking force bar at the end of the gripper, it is possible to shorten the work time for installing the gripper.

(4) By integrally providing the sash and the opening peripheral plate, it is possible to always keep the distance between the sash and the door constant, and the effect of preventing leakage of radio waves can be further enhanced.
