Description

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

Configuration of a conventional example and its problems The configuration of a conventional high frequency heating device will be explained with reference to the drawings. FIG. 1 is an external perspective view of a conventional high-frequency heating device.

FIG. 2 is a sectional view taken along line AA in FIG. In the figure, a heating chamber 2 in which the object to be heated is housed in the main body 1
A door 3 is provided at the opening of the heating chamber 2 so as to be openable and closable. 4 is door 3 when door 3 is closed.
This is an opening peripheral plate with which the inner plate 5 makes surface contact, and is configured to prevent high frequency waves from leaking from inside the heating chamber 2.

In addition, a sash part 6 is formed at the bent upper end of the opening peripheral plate 4, which further extends to form a hook part 7, on which one end of a separate sash cover 8 is hooked, and the other end is hooked on the opening peripheral plate 4. are doing.

Further, FIG. 3 shows another conventional example. Components that are the same as those in FIG. 2 are given the same numbers and their explanations will be omitted.

The high-frequency heating device with such a configuration creates gaps and steps at the joint between the sash section 6 and the sash cover 8, which is not only aesthetically pleasing, but also difficult to clean if food particles get in there, making it difficult to use as a cooking utensil. It was not easy to use.

OBJECT OF THE INVENTION The present invention solves the above-mentioned conventional drawbacks.
The present invention provides 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 includes a heating chamber for storing an object to be heated, a door provided in an opening of the heating chamber so as to be openable and closable, and a door facing around the door. A sash, a sash cover, and an operation panel provided at At least one side is integrally formed with an extension of the opening peripheral plate.

The above configuration increases the strength of the sash, prevents leakage of radio waves, and provides a high-frequency heating device that is easy to clean.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 4 to 8.

In FIG. 4, a heating chamber 11 for storing an object to be heated is provided in a main body 10 of the high-frequency heating device. At the front opening of the heating chamber 11, there is a door 12 which is pivotally supported so as to be openable and closable, and on the side of the door 12,
There is an operation panel 13. The operation panel 13 includes a timer knob 14 for setting the heating time, a cooking start button 15, an indicator lamp 16 for indicating the cooking time,
A cooking time quick reference table 17 is provided.

Next, in FIG. 5, which is a cross-sectional view taken along line A-A' in FIG.
There is 1.

When the door 12 is closed, the inner plate 22 of the door 12 is bent outward above the opening peripheral plate 23 in surface contact to integrally form the upper sash 18, which is then extended and bent. A sash cover 20 is provided. On the other hand, in the lower part as well, the opening peripheral plate 23 is bent outward to integrally form the lower sash 19, which is further extended and bent to form the lower sash cover 21. Upper sash 18 and door 12
The gap L is for opening and closing the door 12, and although it is better to be narrow from the viewpoint of preventing radio wave leakage, it is set to 2 to 4 mm in consideration of mass production. In addition, the height H of the upper sash 18 from the opening peripheral plate 22 is set from 5 mm to the door 12, taking into consideration standards regarding radio wave leakage and appearance.
It may be provided as appropriate within the thickness range of .

Next, FIG. 6, which is a sectional view taken along line BB' in FIG. 4, will be explained. Bend outward at the left side of the opening peripheral plate 23 with which the inner plate 22 of the door 12 makes surface contact when the door 12 is closed;
A left sash 24 is integrally formed, and a left sash cover 26 is provided by extending and bending the left sash 24. On the other hand, on the right side, the right side of the opening peripheral plate 23 is bent outward to integrally form the right sash 25, which is further extended and bent to form the operation panel 13. .

A recess 27 is provided in a part of the operation panel 13, and a cooking time quick reference table 17 is pasted therein. The right side of the main body 1 is fixed to the extending portion of the operation panel 13 with screws 28. The left side of the main body 1 is the left sash cover 26
It is fixed to the extending part with screws 29.

Next, FIG. 7, which is a sectional view taken along line CC' in FIG. 4, will be explained. A timer 3 is installed inside the operation panel 13.
Timer mounting plate 3 with 0 attached with screw 31
2 is fixed to the operation panel 13 by spot welding or the like. The operation panel 13 has a recess 27,
A timer scale plate 33 is attached thereto, a hole 34 is provided through which the timer knob 14 passes, and the timer knob 14 is inserted and attached to the timer shaft 35.

Next, FIG. 8, which is a sectional view taken along line DD' in FIG. 4, will be explained. Inside the operation panel 13 are a cooking start switch unit 36 and an indicator lamp unit 3.
A mounting plate 40 to which 7 is attached with screws 38 and 39 is fixed to the operation panel 13 by spot welding or the like.

On the other hand, the opening peripheral plate 23 is fixed to the side wall 41 of the heating chamber 2 by spot welding or the like. Also the 9th
The figure is a perspective view of the front part that integrates the sash, the sash cover, and the operation panel, and is constructed separately from the exterior member of the heating chamber, making assembly very easy.

In this way, according to the high frequency heating device of this embodiment, the opening peripheral plate 23 of the heating chamber 2 is bent and extended outward to form one side of the sashes 18, 19, 24, 25, and further extended to form the sash cover. 20, 21,
26 and the operation panel 13, the sashes 18, 19, 24, 25, the sash covers 20, 21, 26, and the operation panel 13 are integrated, and are separate from the exterior part of the heating chamber. This allows it to be installed and formed in a stable state without waste. Furthermore, even if food particles adhere to the opening peripheral plate 23 or the sashes 18, 19, 24, and 25, they can be easily cleaned and used, and the assembly process can be simplified and the high-frequency heating device does not leak radio waves. This has the effect of being able to obtain the following.

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

(1) By integrally constructing at least one side of the sash and furthermore the sash cover and the operation panel with the extension of the heating chamber opening peripheral plate, the number of assembly steps can be reduced.

(2) Even if food particles adhere to the opening peripheral plate, it is easy to clean and maintain a clean condition because the opening peripheral plate, the sash, the sash cover, and the operation panel are integrated.

(3) By integrating the sash, the opening peripheral plate, the sash cover, and the operation panel, it greatly contributes to strength, and also contributes to simplifying the main body structure and transport packaging.

(4) By integrating the sash, the opening peripheral plate, the sash cover, and the operation panel, the strength of the sash itself is improved, making it possible to always maintain a constant distance between the sash and the door, which helps prevent radio wave leakage. The effect can be further enhanced.
