DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating cooker, and more particularly, to a heating table which can move a movable table on which an object to be heated is placed outside a heating chamber and weighs the object to be heated. Thus, the weight of the object to be heated can be weighed, and whether or not the moving table should be moved can be controlled.

[0002]

2. Description of the Related Art Japanese Unexamined Patent Publication (Kokai) No. Heisei 2 discloses a heating cooker in which a turntable is rotated by a driving device and can be moved into and out of a heating chamber so that an object to be heated can be easily placed in and taken out of the heating chamber. No. 161214, for example.

[0003]

However, the above-mentioned heating cooker moves at a constant moving speed regardless of the weight of the object to be heated placed on the moving table. In addition, when a heavy object to be heated is placed, the moving table may not be able to move smoothly outside the heating chamber, and in the worst case, the object to be heated may be dropped from the moving table, or the entire cooking device may be damaged. There was a danger of upsetting.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and has a driving device for moving a movable table on which an object to be heated is moved in and out, and a weight of the object to be heated. Based on the weighing device to be weighed and a signal from the weight detecting device, when the detected value is lower than a certain reference value, the movable base is moved at high speed, while the detected value is higher than a certain reference value. In such a case, a control device is provided which controls the drive so that the movable table is moved at a low speed, and when the detected value is higher than a specific value, the movable table is not moved.

[0005]

According to the output of the weight detecting device, the control device determines the heating cooking time, determines whether or not to move the moving table, and if so, how to move the cooking device safely and conveniently. Is controlled to operate.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the cooking device according to the present invention. In this figure, reference numeral 1 denotes a heating chamber for storing an object to be heated, which is provided with a door 2 which can be opened and closed at the front of the heating chamber 1. Reference numeral 3 denotes a heating means for generating energy for heating an object to be heated in the heating chamber 1, and reference numeral 4 denotes a moving table provided so as to be able to move in and out of the heating chamber.
Reference numeral 5 denotes a driving device for moving the movable table into and out of the heating chamber 1. Reference numeral 6 denotes a weight detection device that measures the weight of the object to be heated placed on the moving table 4. Reference numeral 7 denotes an external input device, which includes a cooking button 7a for operating the heating means 3 for heating the object to be heated, and an in / out instruction button 7b for performing an in / out moving operation of the moving table 4 by the driving device 5. 8
Is a control device composed of a microcomputer,
The heating means 3 is controlled in accordance with the type of cooking, and the weight of the object to be heated placed on the moving table 4 is weighed through the above-mentioned weight detecting device, and the moving table is moved by the driving device 5 based on the signal. Whether or not to control the moving speed when moving.

The present invention is configured as described above. Next, the operation will be described.

[0009] When starting cooking of food by electromagnetic waves or electric heat, the door 2 is first opened and then the entry / exit instruction button 7b is operated, so that the movable table moves outside the heating chamber by a fixed amount. When the object to be cooked is placed on the moving table and the entry / exit instruction button 7b is pressed, the moving table is stored in the heating chamber if the weight of the object to be heated is not more than a predetermined weight. At this time, the moving speed of the moving table 4 is controlled in accordance with the detected weight, so that the object to be heated and, consequently, the cooking device main body do not shake abnormally. On the other hand, if a dangerous weight exceeding a predetermined weight is detected, the moving table 4 is not moved, and
A warning or the like is issued to inform the cooking worker to that effect.

When the moving table 4 is accommodated in the heating chamber 1 and the cooking button is pressed after closing the door, the cooking time is calculated in accordance with the weight of the object to be heated detected by the weight detecting device 6. The heating means 3 is drive-controlled to perform the heating cooking.

When the cooking is completed and the door 2 is opened and the entry / exit instruction button 7b is pressed, the moving table 4 on which the object to be heated is placed moves toward the outside of the heating chamber 1. Also at this time, as described above, the moving table 4 is driven at a speed corresponding to the weight of the object to be heated, that is, at a low speed if relatively heavy, and at a high speed when relatively light, and is sent out of the heating chamber.

The above is an example of the operation when the object to be heated is placed on the moving table while the moving table 4 is being sent out of the heating chamber. When the object to be heated is placed on the moving table, substantially the same operation is performed. There is a difference when an object to be heated having a predetermined weight or more is placed, and although heating cooking is enabled, it is prohibited to move the movable table out of the heating chamber after the cooking is completed. That is the point.

[0013]

As described above, according to the present invention, the moving table for mounting the object to be heated is provided, the heating time can be controlled according to the weight of the object to be heated, and the moving table can be controlled according to the weight. Whether or not to move, and if so, how fast the moving speed is, is controlled, so that the cooker can be used safely and conveniently.
