Abstract

PURPOSE:To obstruct the closing of a heating-chamber door under the state, in which a turntable is moved to the outside of a heating chamber, and to prevent the generation of the collision of the door and the turntable, the dropping accident of a substance to be heated, etc. CONSTITUTION:A door-closing preventive device 7 is provided. When a door 6 is brought to an opened state and a turntable 3 is moved to the outside of a heating chamber 1 by a turntable drive 4, the closing of the door 6 is hindered and the device 7 is operated so as to maintain the opened state, thus preventing the generation of the door 6 and the turntable 6, the dropping accident of a substance to be heated, etc.

Description

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, it enables a rotating turntable on which an object to be heated is placed to be moved to the outside of the heating chamber and depending on whether the turntable moves in or out. The closing operation of the heating chamber opening / closing door can be prevented.

[0002]

2. Description of the Related Art Japanese Unexamined Patent Publication No. Hei 2-161214 discloses a heating cooker in which a turntable is rotated by a drive unit and can be moved into and out of a heating chamber to facilitate installation and removal of an object to be heated into the heating chamber. It has been proposed by.

[0003]

In the above-mentioned prior art,
If you try to close the door while the drive is operating and the turntable is moving outside the heating chamber, the door will hit the turntable and damage the glass door, or cook There was a risk of shaking the whole vessel and dropping the heated object from the turntable.

The present invention makes it impossible to close the door when the turntable is moved outside 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, the door is open and the turntable is driven outside the heating chamber by a turntable driving device. When moving, the door closing prevention device is operated so as to prevent the door from closing and maintain the opened state.

[0006]

The controller controls the movement of the turntable toward the outside of the heating chamber and the movement from the outside of the heating chamber to the inside of the heating chamber based on the information from the turntable position detection device. In the moving state, that is, in the state where the door is opened, the 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 An embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the heating cooker according to the present invention, and FIG. 2 is a structural diagram of a door closing prevention device. In these drawings, reference numeral 1 is a heating chamber for containing an object to be heated, 2 is heating means for generating energy for heating the object to be heated in the heating chamber 1, and 3 is an object to be heated in the heating chamber. It is a turntable that can be placed and rotated. Reference numeral 4 denotes a turntable driving device for rotating the turntable and moving it in and out of the heating chamber 1. A turntable position detection device 5 detects a specific portion of the turntable 3 by a non-contact method using light or magnetism, and outputs the position information. 6 is a door provided in front of the heating chamber, and 7
Is a door closing prevention device composed of an arm 8 for controlling the maximum opening angle of the door 6 and a solenoid 9 for locking the arm 8 to prevent the closing operation of the door. The retractable pin 11 of the solenoid 9 is pierced into the notch 10 to prevent the door 6 from being opened.
Reference numeral 12 is a control device composed of a microcomputer, which controls the heating means 2 according to the type of cooking, detects the position of the turntable 3 through the turntable position detection device 5, and turns on the basis of the signal. The table drive device 4 and the door closing prevention device 7 are controlled.

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

During the heating operation using the heating means 2, the turntable 3 is rotationally driven by the turntable driving device 4. Then, after the heating operation is completed, the door 6 is opened, and subsequently, when a signal relating to the movement of the turntable 3 is output from the control device 12 to the turntable drive device 4, the turntable 3 detects the turntable position detection device 5. It is driven by the turntable drive device 4 based on the signal from and is moved toward the outside of the heating chamber. At the same time, the control device 12 operates the door closing prevention device 7 to pierce the retractable pin 11 of the solenoid 9 into the notch 10 of the arm 8 to lock the arm 8, that is, the closing operation of the door 6 is disabled. , Lock the door in the open position.

The turntable 3 is in the closed state of the door.
Is moved by the turntable drive device 4 to return to a predetermined position in the heating chamber 1, and the control device 12 confirms it through the turntable position detection device 5 to release it.

As described above, when the turntable is moving to the outside of the heating chamber, the closing of the heating chamber door is prevented, so that a collision between the door and the turntable and a fall accident of the heated object are surely caused. To be avoided.

[0013]

As described above, according to the present invention, when the turntable is moved to the outside of the heating chamber, the door is fixed in the closed state, so that even if an operation to close the door is performed. , There is no risk of the door hitting the turntable, and there is no risk of dropping the heated object from the turntable.
