  The operation unit 12 includes a lock key 16 for setting key lock, an audio key 17 for setting sound volume, and an operation panel key 18 for returning the operation panel 3 to be inclined or vertical. An automatic cooking key 19 for selecting and setting the automatic cooking menu, a manual cooking key 20 for selecting and setting the manual cooking menu, and a finishing key 21 for setting the finished state of cooking to be harder or softer are arranged side by side. A combination of a human body sensor 22 that is arranged and configured with an infrared sensor or an ultrasonic sensor below these keys, and a switch key 23 that switches the output from the human body sensor to valid or invalid, and a temperature key that sets the cooking temperature 24 and 24 are arranged side by side, and three time keys 25... For setting the time and timer time are arranged side by side below these keys. And, it is arranged cancel key 27 and the start key 26 under these time keys.

  FIG. 4 shows an embodiment of the control circuit 30 constituting the control means. A power supply circuit 33 is connected to a commercial AC power supply 31, and a microcomputer 34 is connected to the output of the power supply circuit.

  The output port of the microcomputer 34 drives a display circuit 35 for driving the display 11, a buzzer circuit 37 for operating the buzzer 36, and a geared motor 9 for tilting the operation panel 3 electrically. A motor drive circuit 39 that operates, an electromagnetic valve drive circuit 41 that drives an electromagnetic valve 40 that controls fuel supply to a gas burner (not shown) that is a heat source of the cooker body 1, and an igniter 42 that ignites the gas burner An igniter drive circuit 43 that connects to an interior light drive circuit 45 that flashes an interior light 44 that illuminates a cooking chamber (not shown) formed inside the door 2, and opens and closes the door 2. The output of the door opening / closing detection circuit 46 for detecting the input, the output of the key input circuit 47 for detecting the input of each operation key arranged in the operation unit 12, and the temperature of the cooking chamber (not shown) The output of the internal temperature detection circuit 48 to detect, the output of the flame detection circuit 49 to detect the ignition of the gas burner, and the human body detection circuit 50 to detect the presence or absence of a human body from the output of the human body sensor 22 are connected, A data storage memory 51 is connected to the input / output port.

  Thus, when a human body approaches the front surface of the cooker body 1, this is detected by the output of the human body sensor 22, and the microcomputer 34 detects the first predetermined time (for example, the human body detection circuit 50 sets in advance). 3 seconds), when the human body is detected, the geared motor 9 is actuated by the output of the motor drive circuit 39 to tilt the operation panel 3 as shown by the broken line in FIG. Easy to operate.

  Thereby, each key is operated from the operation unit 12 of the tilted operation panel 3 to input cooking conditions, the door 2 is opened, the food to be cooked is installed in a cooking chamber (not shown), the door 2 is closed, and the start switch 26 is closed. Start cooking by turning on.

  On the other hand, when the start key 26 is turned on and cooking is started, the microcomputer 34 reverses the geared motor 9 when a second predetermined time (for example, 2 seconds) elapses after the start key is turned on. The operation panel 3 is configured to return to the vertical state.

  When the door 2 is opened and energized, the microcomputer 34 operates the geared motor 9 with the output of the motor drive circuit 39 to tilt the operation panel 3 as shown by the broken line in FIG. Each key arranged in the section 12 is configured to be easily operated.

  Further, the microcomputer 34 detects the approach of the human body for the first predetermined time or more, but if the microcomputer 34 no longer detects the approach of the human body for the third predetermined time (for example, 5 seconds), the motor drive circuit The geared motor 9 is reversed at an output of 39 to return the operation panel 3 to the vertical state.

  With these configurations, when the human body is separated from the front surface of the cooker for a predetermined time or longer, the operation panel 3 is automatically stored to prevent the human body or the object from touching the operation panel due to forgetting to store the operation panel. In addition, the human body and the operation panel 3 are prevented from being damaged by these contacts.

  On the other hand, if it is complicated to enter and exit the cooking device main body due to the installation conditions of the cooking device main body 1, the human body detection by the human body sensor 22 is invalidated by the operation of the switching key 23 and the human body approaches. The operation panel 3 is set not to tilt.

  As a result, the operation panel 3 does not unnecessarily repeat tilting and storing, and it is possible to prevent failure of the electric mechanism 10 and deterioration of durability due to repetition.

  When the microcomputer 34 detects a human body by the human body sensor 22 and the operation panel 3 is tilted, no input operation is performed for a fourth predetermined time (for example, 30 seconds) from each key arranged on the operation unit 12. In this configuration, the geared motor 9 is reversed to return the operation panel 3 to a vertical state.

  As a result, even if a human body is near the cooker body 1, it is determined that no operation is performed and the operation panel 3 is stored in a vertical state, thereby preventing unnecessary tilting of the operation panel 3. It is possible to reliably prevent contact of the human body due to the protrusion 3.

  In addition, each predetermined time in the said Example can be changed arbitrarily, You may comprise so that these setting time can be changed by the user.

It is a front view which shows the Example of this invention. It is a side view of the principal part similarly. It is a front view of an operation panel similarly. It is also a block diagram of a control circuit.
