Abstract

PURPOSE:To provide a cooking device having a structure capable of opening or closing a door even if a moving table is present in a heating chamber or the moving table is moved out of the heating chamber, useless releasing of atmosphere of high temperature in the heating chamber is prohibited even in the case that the moving table is present outside the heating chamber and energy saving is provided. CONSTITUTION:A heating and cooking device is provided with a door opening or closing device 7 for use in driving to open or close a door 6 for use in opening or closing a heating chamber and has a structure in which the heating chamber 1 can be opened or closed in response to the state in which the moving table 4 is moved out of the heating chamber 1 or another state in which the moving table is stored in the heating chamber 1 as required. Atmosphere of high temperature within the heating chamber is prevented from being uselessly discharged out of the heating chamber while the moving table 4 is being moved out of the heating chamber while repeating the heating and cooking operation.

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

[0002]

2. Description of the Related Art Japanese Patent Application Laid-Open No. HEI 2-A2 has disclosed that a turntable of a cooking device can be rotated by a driving device and moved inside and outside a heating chamber so that an object to be heated can be easily placed in and taken out from the heating chamber. It is proposed by Japanese Patent No. 161214.

[0003]

In the above-mentioned prior art,
When the drive unit is activated to move the moving table outside the heating chamber and the door is closed, the door hits the moving table and the heating chamber cannot be closed.

Therefore, when the heating chamber is preheated to start cooking or when the heating cooking is repeated, it is not possible to prevent the release of the high temperature atmosphere in the heating chamber, which is a problem in terms of energy saving.

[0005]

According to the present invention, the door can be opened and closed not only when the moving table is inside the heating chamber but also when the moving table is moved outside the heating chamber to prevent an unnecessary decrease in the temperature inside the heating chamber. I chose

[0006]

The door can be opened / closed not only when the movable table is inside the heating chamber but also when it is moved outside the heating chamber, and an unnecessary decrease in the temperature inside the heating chamber is prevented.

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. In FIG. 1, reference numeral 1 is a heating chamber for accommodating 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 a temperature inside the heating chamber 1. Is a temperature detecting means for detecting the temperature in the heating chamber 1 by a non-contact method using a thermistor or the like, and outputs the information.
Reference numeral 4 denotes a moving table on which an object to be heated is placed, and 5 is a drive device for moving the moving table 4 in and out of the heating chamber 1 with a conventionally well-known combination of a rack 10 and a pinion 11. 6
Is a door for opening and closing the heating chamber 1 that can be opened and closed as needed when the moving table 4 is moved to the outside of the heating chamber 1 by the drive device 5 or stored in the heating chamber 1. A door opening / closing device 7 opens and closes the door 6 by a combination of the rack 12 and the pinion 13. Reference numeral 8 is an external input means for inputting information related to heating operation, driving of the moving base, and opening / closing operation of the door from the outside as needed, and is constituted by, for example, a key switch. Reference numeral 9 denotes a control device composed of a microcomputer, which is a temperature detecting means 3
The heating means 2 is drive-controlled based on the temperature information detected by the, or the drive device 5 is drive-controlled based on the information input from the external input means 8 to move the moving table 4 in and out of the heating chamber. Alternatively, the door opening / closing device 7 is drive-controlled to open / close the door for opening / closing the heating chamber.

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

During the heating operation using the heating means 2 as in the conventional case, the movable table 4 on which the object to be heated is placed is housed in the heating chamber. In this case, since the lower end portion 6a of the door 6 and the front end upper surface 4a portion of the moving table 4 are in close contact with each other, the heating chamber is sealed and the temperature inside the heating chamber is kept in a heated state. Then, after the heating operation is completed, the opening operation of the door 6 and the moving table 4 from the external input means 8 are performed.
When the information requesting the movement of each of them is output to the control device 9, the door 6 is opened by the combination of the rack 12 which is the door opening / closing device 7 and the pinion 13 according to the information from the control device 9, and then the moving table is moved. 4 is a combination of a rack 10 and a pinion 11 that form a drive unit 5 and is moved toward the outside of the heating chamber.

FIG. 2 is a vertical cross-sectional view showing a state where the heating cooking is further repeated in the heating cooker of the present invention.

When the heating and cooking are repeated, the information for 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 to the outside 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 rear end upper surface 4b portion of the movable table 4 are in close contact with each other, it is possible to prevent wasteful discharge of the high temperature atmosphere in the heating chamber.

The heating operation is requested from the external input means 8 for the purpose of maintaining the temperature of the heating chamber or raising the temperature even while the moving table 4 is moved to the outside of the heating chamber to perform the necessary cooking work. When the information is output to the control device 9, the control device 9 drives and controls the heating means 2 until the temperature detecting means 3 detects a predetermined heating chamber temperature.

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 unit 7 is drive-controlled again to close the door 6, and then the cooking The heating means 2 is controlled according to the type.

In any of the above-mentioned operation steps, when the information requesting the operation interruption is output from the external input means 8 to the controller 9, the controller 9 immediately interrupts the drive control. To do.

[0017]

As described above, according to the present invention, it is possible to preheat the heating chamber because the door can be opened and closed even when the movable table is inside the heating chamber or moved outside the heating chamber. As a result, the cooking time for re-cooking can be shortened, and at the same time, unnecessary discharge of the high temperature atmosphere in the heating chamber can be prevented, and the cooking work in consideration of energy saving can be performed.
