Description

[Detailed Description of the Invention] The present invention relates to a heating cooker such as a microwave oven, and more specifically relates to the structure of an opening/closing door in a heating cooker.

In conventional heating cookers of this type, a single door is typically pivotally mounted to an opening formed on the front surface of the main body case through which the food to be cooked can be taken in and out.

In this case, even when taking out or putting in a relatively small object to be cooked, the opening must be completely opened, resulting in a problem that the internal temperature decreases.

That is, it was not possible to adjust the degree of opening of the opening depending on the size of the food to be cooked.

In view of the above-mentioned problems, the present invention divides the opening/closing door provided at the front opening of the main case into a main door and a small door that can operate independently of the main door. The object of the present invention is to provide a heating cooker that can selectively open the main door or the small door depending on the size of the cooking device, thereby minimizing the drop in internal temperature. It is.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, heating cookers according to some embodiments of the present invention will be described with reference to the accompanying drawings.

What is shown in FIGS. 1 to 4 is a first embodiment of the present invention.

In the figure, reference numeral 1 denotes a main body case, and the main body case 1 has a double wall structure including an inner case 2 and an outer case 3.

Inside the main body case 1, electric heaters 4°4 are arranged above and below, and directly above the lower electric heater 4, a wire mesh-like mounting table 5 for placing the food to be cooked is placed on the inner case 2. side wall 2a of
It is supported slidably in the front-rear direction by a support 6 fixed to.

The mounting table 5 is horizontally movable by inserting and guiding the upper end of an arm rod 7 erected at the rear end into a guide rail 8 fixed to the side wall 2a of the inner case 2.

On the other hand, an opening 9 is formed on the front surface of the main body case 1 to allow food to be cooked in and out.

With respect to the opening 9, the main door 10 has its lower end aligned with the shaft 11.
It is pivoted so that it can rotate in an arc in the vertical direction.

Reference numeral 12 is a handle for the main door.

The main door 10 is formed with a small door 13 that can be divided into substantially the entire width from the middle to the lower end and can be operated independently.

The front end of the mounting table 5 is connected to the inner surface of the lower end of the small door 13, and the small door 13 is horizontally movable in the front-rear direction together with the mounting table 5.

Reference numeral 14 is a small door handle.

As shown in FIG. 5, the small door 13 may have its lower end pivotally connected to the front end of the mounting table 5 by a shaft 15 so as to be rotatable in an arc.

Reference numeral 16 is a return spring.

Next, to explain the operation of the heating cooker shown in FIGS. 1 to 4, when cooking a relatively small object, the third
If only the small door 13 is pulled out horizontally as shown in the figure, the mounting table 5 is also pulled out together with the small door 13, and the food to be cooked can be easily taken in and out.

At this time, since only the small door 13 portion of the opening 9 is opened, the drop in internal temperature can be minimized.

In addition, when cooking a large object to be cooked, as shown in FIG. You can easily take things in and out.

As shown in FIG. 5, if the small door 213 is allowed to rotate in an arc relative to the mounting table 5, the opening 9 can be opened completely by simply rotating the main door 10 and the small door 13 in an arc. Become.

What is shown in FIGS. 6 to 8 is a second embodiment of the present invention.

In this case, the small door 13 has its lower end pivotally supported on the front end of the mounting table 5 by a shaft 15 so as to be able to rotate freely in an arc, while the inward step 18 formed at its upper end is connected to the front end of the main door 10. It is engaged with an outward step 19 formed on the upper edge of the door opening 17 and rotates in an arc in conjunction with the main door 10.

In this way, the small door 13 can be pulled out horizontally by itself as shown in FIG. 7, and can also be rotated in an arc in conjunction with the main door 10 as shown in FIG.

That is, when opening the opening 9 completely, it is sufficient to simply rotate the main door 10 in an arc.

What is shown in FIGS. 9 to 11 is a third embodiment of the present invention.

In this case, the upper end of the small door 13 and the upper edge of the small door opening 17 in the main door 10 are connected via a detachable locking device 20.

As shown in FIG. 11, the lock device N20 consists of a lever 21 which is rotatable in an arc and which is provided at the upper end of the small door 13.
1, and a locking rod 22 that can be moved up and down.

The locking rod 22 is urged downward by a spring 23, while the claw piece 24 at the upper end is fitted into an engagement hole 25 formed at the upper edge of the small door opening 17.

Therefore, when the small door 13 rotates the main door 10 in an arc,
The locking device 20 rotates slightly around the locking rod 22 as a fulcrum.

In this way, the lever 21 is rotated arcuately in the direction shown by arrow A in FIG.
If the engagement between the small door 13 and the engagement hole 25 is released, the small door 13 can be pulled out horizontally by itself.

Furthermore, if the main door 10 is rotated in an arc while the locking device 20 is in the locked state, the small door 13 will rotate slightly in an arc using the locking rod 22 of the locking device 20 as a fulcrum, as shown in FIG. It rotates in an arc in conjunction with.

At this time, the mounting table 5 is pulled by the small door 13 and pulled out slightly.

In each of the above-mentioned embodiments, the small door 13 is formed to cover almost the full width of the main door 10, but when the width of the small door 13 is formed to be small, the mounting table 5 is a part that interlocks with the small door 13. It is also possible to form the fixed part separately.

Next, the effects of the cooking device of the present invention will be listed below.

That is, according to the present invention, (1) A part of the main door 10 is pivotally connected in an arc to an opening 9 formed on the front surface of the main case 1 for entering and exiting food. A small door 13 that can be divided and operated independently is provided so that the main door 10 or the small door 13 can be selectively opened depending on the size of the food to be cooked, so that it is easy to take in and take out the food to be cooked. The drop in internal temperature during this process can be minimized.

- (2) Since the small door 13 is connected to all or a part of the mounting table 5 and is movable horizontally in the front and back direction, when the small door 13 is opened, the mounting table 5 is also pulled out at the same time. Therefore, the food to be cooked can be taken in and out easily.

It has such practical effects.
