Abstract

PURPOSE:To contrive to reduce the working cost and to improve the appearance by a method wherein a decorative frame forming member and a frontal decorative panel forming member, both of which form the decorative frame member and the frontal decorative panel member of a door, are formed out of the same forming member and during the same working process. CONSTITUTION:A door 2 consists of a main frame 3, a decorative frame 4, a frontal decorative panel 5, and a special glass plate 6. The decorative frame 4 is formed by drawing a decorative frame forming member and the like. The frontal decorative panel 5 is formed by drawing a frontal decorative panel forming member and the like. In this case, the frontal decorative panel forming member is composed of the same member integral with the decorative frame forming member. The drawings of both members at the respective predetermined positions are performed during the same working process, during which the frontal decorative panel forming member is sequentially punched out so as to independently constitute both members, of which the frontal decorative panel and the decorative frame are respectively formed independently after punching out.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a method of processing an opening/closing door provided in a high-frequency heating device such as a microwave oven.

Conventionally, the opening/closing door of this type of heating cooker has, for example, a rectangular main frame, a decorative frame attached to cover the outer peripheral wall of the main frame of the door, and an inner periphery on the front side of the main frame. Some cooking appliances are comprised of a front decorative plate provided at the end and a transparent member that overlaps the front decorative plate and allows the inside of the cooking chamber to be viewed.

In such an opening/closing door, each part, such as the main frame, decorative frame, front decorative plate, etc., is processed separately.

For this reason, the time and effort required to process each of the above-mentioned parts is expended individually, and therefore the processing cost is also required separately for each part.

The present invention has been made by paying attention to such conventional situation,
A processing method is proposed in which a decorative frame forming member forming a decorative frame member and a decorative plate forming member forming a front decorative plate member can be simultaneously processed and formed using one forming member. This aims to reduce processing costs and improve aesthetic appearance.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the accompanying drawings.

In the figure, A is the main body of the microwave oven, 1 is a main body frame, and 2 is an opening/closing door attached to the main body frame 1.

Reference numeral 3 is a main frame as a door main frame member of this opening/closing door 2, and the main frame 3 is bent into a U-shape over the entire circumference of the approximately square outer peripheral end.
In addition to forming a chalk chamber (a), a peephole (3b) with a special glass attached is formed in the center.

Reference numeral 4 denotes a decorative frame as a decorative frame member formed in a gate shape so as to cover the outer surface of the main frame 3 except for the lower surface of the outer circumferential wall. The ends are bent inward and the inner surface of the decorative frame 4 is welded to the outer surface of the main frame 3 to be fixed. Here, the depth dimension of the decorative frame 4 is formed to be longer than the depth dimension of the main frame 3 by a predetermined dimension, and after the decorative frame 4 and the main frame 3 are fixed, the front side of the main frame 3 and the front end of the decorative frame 4 The structure is such that a gap having a dimension X shown in FIG. 3 is provided between the inner surface of

5 is a front decorative plate which is inserted and fixed together with a special glass plate 6 as a transparent member into this gap, and is formed by drawing the front decorative plate forming member, and has an opening 5a of a predetermined size in the center. Parts of four corners are cut out so that the special glass plate 6 is elastically biased and pressed against the end of the decorative frame 3.

In addition, the main frame 3. Decorative frame 4. The front decorative plate 5 and the special glass plate 6 constitute the opening/closing door 2.

Here, the front decorative plate forming member is the same member that is integrated with the decorative frame forming member, and drawing υ processing is performed at each predetermined position of both L members in the same processing step. The members for forming the front decorative plate are sequentially punched out, and the two members are formed separately by the punching, and then the front decorative plate and the decorative frame are separately formed from both members.

Next, to explain the manufacturing process of the opening/closing door 2 having such a configuration, a gate-shaped decorative frame 4 is welded to the top surface of the main frame 3 and both left and right sides to form a gap of the above-mentioned X dimension, and the lower side Insert the front decorative plate 5 and the special glass plate 6, then cover the lower surface of the main frame 3 and the lower end surface of the decorative frame 4 with the lower decorative frame 4a, and fix the lower decorative frame 4a with screws etc. It is formed by fixing it to a tool.

Note that the gate-shaped decorative frame 4 and the main frame 3 are painted after they are welded.

As described above, the opening/closing door 2 according to the present invention has the following features:
Since the decorative frame A and the front decorative plate 5, which are the constituent members, can be processed into the same forming member in the same processing process, processing costs can be significantly reduced compared to the conventional processing of each separately. , productivity can also be improved.

In addition, since bending work including bending and drawing of parts of the corners on both sides of the upper end of the decorative frame 4 can be performed, there is no combining part as in the past, eliminating the need for connection by welding etc. at the part of the corner, thereby improving the aesthetic appearance. At least its design quality can be enhanced.

In addition, according to this embodiment, it is possible to eliminate the trouble of painting the decorative frame portion and the main frame portion of the door separately as in the conventional case, and to paint the decorative frame portion 4 and the main frame portion of the door separately.
Since it can be painted integrally after welding with the product, manufacturing efficiency can be further improved.

As explained above, according to the present invention, the decorative frame forming member and the front decorative plate forming member that form the decorative frame member and the front decorative plate member of the opening/closing door are made of the same forming member and processed in the same manner. Since it can be formed in-process, it is possible to provide a method for processing the opening/closing door of a high-frequency heating device that reduces processing costs for both members and also improves aesthetic appearance.
