Description

[Detailed description of the invention] (a) Industrial application field The present invention mainly relates to a door device for a microwave oven used to heat and cook food.

(B) Prior Art Generally, the door used in a microwave oven is equipped with a glass plate on the front side, and this glass plate has its periphery separated by a Since it is fixedly supported using a dedicated support member, there is a problem in that the number of parts and the number of assembly steps are relatively large.

(c) Problems to be solved by the invention The purpose of the invention is to reduce the cost of the glass plate fixing member attached to the front of the door body.

(d) Means for solving the problem The present invention is to attach a glass plate to the front of the door body which is attached to the front opening of the cooking chamber so that it can be opened and closed vertically, and a handle is attached to the upper front of the door body. In the device to be mounted, a locking groove for locking the lower end of the glass plate is provided at the lower front end of the door body, and a fixing part that covers the upper end of the glass plate is integrally formed in the handle, and the fixing part On the part facing the glass plate,
A storage section for storing an elastic material such as a spring is integrally formed, and the upper end of the glass plate is held down and fixed via the elastic material.

(E) Function When attaching a glass plate to the front of the door body, after attaching the glass plate to the specified position on the door body while securing its lower end to the locking groove, fix the handle to the upper front of the door body. By doing so, the other end of the glass plate is held and fixed by the fixing part of the handle.

(F) Embodiment An embodiment of the present invention will first be explained based on FIG. 1. Reference numeral 1 indicates a relatively small microwave oven body, which defines a cooking chamber 4 with an opening 3 at the front inside an outer case 2. At the same time, a vertically opening door 5 is attached to the opening 3 so as to be openable and closable.

In addition, high-frequency radio waves are supplied into the cooking chamber 4 by a magnetron (not shown), and hot combustion air from a gas burner is supplied from a large number of air supply holes 7, 7, . . . formed in the rear wall plate 6 of the cooking chamber 4. A turntable 8 is also disposed at the bottom of the cooking chamber 4.

An operation panel 9 is provided below the door 5 on the front side of the microwave oven body 1, and this operation panel includes selection switches 10, 10, . . . for selecting the high frequency heating, combustion hot air heating, simultaneous heating, etc., as well as oven cooking Temperature setting switches 11, 11, . . . , a display 12, a start switch 13, etc. are provided for setting the temperature inside the cooking chamber 4 at the time of cooking.

On the other hand, as shown in FIG. 2, the door 5 includes a door body 16 that has a window hole 14 formed approximately in the center and a chiyoke groove 15 around the window hole, and Support plate 17 and presser plate 1 on the back side
8, a cover 21 that closes the entrance 20 of the chiyoke groove 15, and a front glass plate 22 attached to the front surface of the door body 16;
It mainly consists of a handle 23 similarly attached to the other end of the front surface.

As shown in FIGS. 3 and 4, the front glass plate 22 has its lower end 22' locked in a locking groove 24 formed at the lower front end of the door body 16, and its upper end 22'' is held down and fixed by a pair of left and right fixing parts 25, 25 integrally provided at the lower part of the handle 23.As shown in FIG. 26, and an elastic member such as a coil spring 27 that presses and biases the front glass plate 22 is housed in this housing part.

When assembling the door 5, the back glass plate 19 is attached to the back window hole 14 portion of the door body 16 using the support plate 17 and the presser plate 18, and the cover 21 is attached to the entrance 20 of the chiyoke groove 15. After the lower end 22' of the front glass plate 22 is engaged in the locking groove 24, the upper end 22'' of the front glass plate 22 is attached to the handle 23, and the coil spring 27 is fixed at the fixed part of the handle 23. Fix the presser foot through the presser foot.

(G) Effects of the invention With the configuration of the invention, by fixing the glass plate using the handle used to open and close the door, it is possible to reduce the number of parts for fixing the glass plate, and also to fix the glass plate using the handle used to open and close the door. By holding down the glass plate, it is possible to prevent damage to the fixed part or the glass plate due to the load applied to the handle when opening and closing the door, and the glass plate is fixed at the same time as the handle, improving assembly work efficiency. .
