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 cooker in which a rotating turntable on which an object to be heated is placed can be moved outside a heating chamber and the turntable can be moved in and out. It is possible to prevent the closing operation of the heating chamber opening / closing door.

[0002]

2. Description of the Related Art Japanese Unexamined Patent Publication (Kokai) No. 2-161214 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 to facilitate installation and removal of an object to be heated into and out of the heating chamber. And so on.

[0003]

In the above-mentioned prior art,
If you try to close the door while the drive is operating and the turntable is moving out of the heating chamber, the door will hit the turntable, damaging the glass door or cooking. There is a danger that the object to be heated is dropped from the turntable by shaking the entire vessel.

According to the present invention, the door cannot be closed when the turntable is moved out of the heating chamber.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention comprises a door closing prevention device, wherein the door is opened and the turntable is moved out of the heating chamber by a turntable driving device. When moving, the door closing prevention device is operated so as to prevent the door from being closed and maintain the opened state.

[0006]

The control device controls the movement of the turntable to the outside of the heating chamber and the movement of the turntable from the outside of the heating chamber to the heating chamber based on the information of the turntable position detection device. In a moving state, that is, in a state where the door is opened, information for preventing the door from being closed is output to the door closing prevention device, so that the door cannot be closed.

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 of the present invention, and FIG. 2 is a structural view of a door closing prevention device. In these figures, reference numeral 1 denotes a heating chamber for storing an object to be heated, 2 denotes a heating means for generating energy for heating the object to be heated in the heating chamber 1, and 3 denotes a heating means in the heating chamber. It is a turntable that is placed and rotated. Reference numeral 4 denotes a turntable driving device that moves the inside and outside of the heating chamber 1 in addition to rotating the turntable. Reference numeral 5 denotes a turntable position detecting device which detects a specific portion of the turntable 3 by a non-contact method using light or magnetism and outputs position information thereof. 6 is a door provided on the front of the heating chamber, and 7
Is a door closing prevention device comprising an arm 8 for regulating the maximum opening angle of the door 6 and a solenoid 9 for locking the arm 8 to prevent the door from closing. The notch 10 is pierced by the pin 11 of the solenoid 9 to prevent the door 6 from being closed.
Reference numeral 12 denotes a control device constituted by a microcomputer, which controls the heating means 2 in accordance with the type of cooking, detects the position of the turntable 3 through the turntable position detecting device 5, and turns on the basis of the signal. It controls the table driving device 4 and the door closing prevention device 7.

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

During the heating operation using the heating means 2, the turntable 3 is driven to rotate by the turntable driving device 4. Then, after the heating operation is completed, the door 6 is opened, and subsequently, a signal relating to the movement of the turntable 3 is output from the control device 12 to the turntable driving device 4. Is driven by the turntable driving device 4 on the basis of a signal from the heating chamber and is moved out of the heating chamber. At the same time, the control device 12 activates the door closing prevention device 7 to pierce the notch 10 of the solenoid 9 into the notch 10 of the arm 8 to lock the arm 8, that is, disable the door 6 closing operation. , Secure the door open.

The door closing prevention state is determined by the turntable 3
Is moved by the turntable driving device 4 to return to a predetermined position in the heating chamber 1, and is released when the control device 12 confirms it through the turntable position detecting device 5.

As described above, in the state where the turntable is moved outside the heating chamber, the closing of the heating chamber door is prevented, so that the collision between the door and the turntable, the falling accident of the object to be heated, and the like are reliably generated. To be avoided.

[0013]

As described above, according to the present invention, when the turntable is moved out of the heating chamber, the door is fixed in the closing prevention state, so that even if the door is closed, the door is fixed. There is no danger of the door hitting the turntable, and no danger of dropping the object to be heated from the turntable.
