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 an object to be heated can be moved outside a heating chamber by a moving table, and before or after the moving table is moved. The opening / closing operation of the opening / closing door can be performed.

[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]

In the above-mentioned prior art,
If the driver attempts to close the door with the moving table moved outside the heating chamber, the door hits the moving table and the heating chamber cannot be closed.

[0004] Therefore, when cooking is started by preheating the heating chamber or when cooking is repeated, release of the high-temperature atmosphere in the heating chamber cannot be prevented, and there is a problem in energy saving.

[0005]

SUMMARY OF THE INVENTION According to the present invention, the door can be opened and closed not only when the moving table is in the heating chamber but also when the moving table is moved outside the heating chamber, thereby preventing unnecessary lowering of the temperature in the heating chamber. I made it.

[0006]

The door can be opened and closed even when the moving table is outside the heating chamber, as well as when the moving table is outside the heating chamber, so that unnecessary lowering of the temperature of the heating chamber is prevented.

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 FIG. 1, reference numeral 1 denotes a heating chamber for accommodating 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 temperature in the heating chamber 1. Temperature detecting means for detecting the temperature in the heating chamber 1 by a non-contact method using a thermistor or the like and outputting the information.
Reference numeral 4 denotes a moving table on which the object to be heated is mounted. Reference numeral 5 denotes a drive device for moving the moving table 4 in and out of the heating chamber 1 by a well-known combination of a rack 10 and a pinion 11. 6
Reference numeral denotes a heating chamber opening / closing door that can open and close the heating chamber 1 as needed in a state where the moving table 4 is moved out of the heating chamber 1 by the driving device 5 or is accommodated in the heating chamber 1. A door opening / closing device 7 drives the door 6 to open / close by a combination of the rack 12 and the pinion 13. Reference numeral 8 denotes an external input means for inputting information relating to the heating operation, the driving of the moving table, and the opening / closing operation of the door from the outside as necessary. Reference numeral 9 denotes a control device composed of a microcomputer.
To control the driving of the heating means 2 on the basis of the information on the temperature detected by the controller, or to control the driving of the driving device 5 based on the information inputted from the external input means 8 to move the movable table 4 in and out of the heating chamber. Alternatively, a door opening / closing door is opened and closed by driving and controlling the door opening / closing 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 as in the conventional case, the moving table 4 on which the object to be heated is placed is housed in the heating chamber. In this case, since the lower end 6a of the door 6 and the upper surface 4a of the front end of the movable base 4 are in close contact with each other, the heating chamber is closed, and the temperature of the heating chamber is maintained in a heated state. After the heating operation is completed, the opening operation of the door 6 and the moving table 4 are performed by the external input means 8.
Is output to the control device 9, the door 6 is opened by a combination of the rack 12 and the pinion 13, which are the door opening / closing device 7, according to the information from the control device 9, Reference numeral 4 denotes a combination of a rack 10 and a pinion 11 constituting the driving device 5 and is moved toward the outside of the heating chamber.

FIG. 2 is a longitudinal sectional view showing a state in which heating cooking is repeated in the cooking device of the present invention.

When heating and cooking are repeated, information requesting the closing operation of the door 6 is output from the external input means 8 to the control device 9 even when the movable table 4 is moved out of the heating chamber 1. Then, the door 6 is closed by the door opening / closing device 7 according to the information from the control device 9.

In this case, since the lower end portion 6a of the door 6 and the upper surface 4b of the rear end of the movable table 4 are in close contact with each other, the high-temperature atmosphere in the heating chamber is prevented from being wasted.

A heating operation is requested from the external input means 8 for the purpose of maintaining or increasing the temperature of the heating chamber even while the movable table 4 is being moved out of the heating chamber and performing a necessary cooking operation. When the information is output to the control device 9, the control device 9 controls the driving of the heating means 2 until a predetermined heating chamber temperature is detected through the temperature detection means 3.

When the temperature in the heating chamber 1 detected by the temperature detecting means 3 reaches the required temperature, the control device 9 outputs information to the heating means 2 to stop the heating operation. The control device 9 drives and controls the door opening / closing device 7 to control the door 6.
Is opened, the drive unit 5 is drive-controlled to store the movable table 4 in the heating chamber 1, and after the storage is completed, the door opening / closing device 7 is drive-controlled again to close the door 6, and then the cooking is started. The heating unit 2 is controlled according to the type.

In any of the above-described operation steps, when the information requesting the interruption of the operation is output from the external input means 8 to the control device 9, the control device 9 immediately stops the drive control. I do.

[0017]

As described above, according to the present invention, the door can be opened and closed whether the moving table is in the heating chamber or moved outside the heating chamber, so that the heating chamber can be preheated. This makes it possible to shorten the cooking time of the re-cooking, and at the same time, to prevent unnecessary release of the high-temperature atmosphere in the heating chamber, thereby making it possible to perform energy-saving cooking work.
