When the long press time is, for example, 1 second or less and the release operation is performed, the error determination means 94 determines an error because the ignition operation is not ensured (for example, a finger touches lightly), and the long press time is 2 When the release operation is performed for a second or more, the error determination means 94 determines that the ignition operation is not ensured (for example, the finger is accidentally placed). Further, even when the ignition display 78 is continuously input a plurality of times (twice or more), the error determination means 94 determines that the ignition operation is incorrect.

When the error is determined in this way, the error signal generation means 96 generates an error signal, and the control means 86 operates the notification means 102 based on the error signal to notify that the error operation has been performed. The notification means 102 is composed of a notification buzzer, a notification lamp, and the like. In the case of the notification buzzer, an error operation is notified by a notification sound, and in the case of a notification lamp, a notification light (for example, lighting, blinking, etc.) is used. Notifying that the error operation has been performed, the operator can know that the ignition is not burned due to the error operation. The notification of this error operation (notification sound, notification light) disappears in about 1 to 3 seconds for re-operation, and after the error notification disappears, the operator comes to input and operate the ignition display 78 again.

Further, when the combustion of the first cooking burner 10 is stopped, the operator comes to perform a pseudo input operation of the stop display 72 of the operation display unit 68, and the input operation is operated by the input operation. The signal generation means 92 generates a stop signal as described above, and based on this stop signal, the on-off valve 22 of the first cooking burner 10 is closed and the supply of fuel gas is stopped. In the case of this fire extinguishing, since the operation signal generating means 92 generates a stop signal when the finger is positioned on the stop display 72, the combustion of the first cooking burner 10 is completed immediately after the fire extinguishing operation, and the safety at the time of extinguishing the fire is completed. Sex can be ensured.

Further, when the combustion of the first cooking burner is down (or up), the operator comes to perform a pseudo input operation on the down display 74 (or up display 76) of the operation display unit 68. In the input operation, the operation signal generation means 92 generates a down signal (or up signal) as described above when the finger is released after the input operation, and the first cooking is based on the down signal (or up signal). The flow control valve 26 of the burner 10 reduces (or increases) the flow rate of the fuel gas, whereby the combustion flame of the first cooking burner 10 becomes smaller (or larger).

In this embodiment, an ignition signal (operation signal) is generated when the ignition display 78 (operation display) is pressed and held and then the finger is released during the ignition operation (operation operation). Alternatively, it may be configured to generate an ignition signal when the ignition display 78 is continuously input-operated (operated twice continuously), and even if it is configured in this way, an erroneous operation of the ignition operation may be performed. Can be reduced. In this case, the error determination means 94 determines an error when the ignition display 78 is continuously operated three or more times.

Further, in this gas heating cooker 2, a pot detection heating function and a combustion / combustion function are provided so that cooking can be safely performed using the first cooking heating burner 10 (second and third cooking heating burners 12, 14). A fire extinguishing display mechanism is installed. The first cooking heating burner 10 is provided with a first pot detecting means 58, and the first heating display means 32 (LED display device) has two types of plurality of LEDs, for example, red (or orange) as a specific color. It is provided with a red LED 112 that lights and displays (such as) and a blue LED 114 that lights and displays, for example, blue (or green) as another color different from the specific color.

Since it is configured in this way, when a cooking pot (not shown) is placed on the trivet 28 of the first cooking burner 10 with the power switch 40 turned on, the first pot detecting means 58 becomes the trivet. The cooking pot placed on the 28 is detected, and the detection signal from the first pot detecting means 58 is sent to the controller 84. When the cooking pot is detected in this way, the combustion permission signal generation means 98 generates a combustion permission signal, and the blue LED 114 of the first heating display means 32 lights up based on the combustion permission signal. It is displayed that the first cooking burner 10 is in a cookable state but is in a fire extinguishing state.

Further, when the ignition display 78 of the operation display unit 68 is input-operated as described above from such a state, the operation signal generation means 92 generates an ignition signal (operation signal), and the first cooking is based on this ignition signal. The burner 10 is ignited and burned as described above, and the red LED 112 of the first heating display means 32 is turned on (at this time, the blue LED 114 is turned off) based on this ignition signal, and the first cooking burner 10 is burned. Display that it is in a state. It is desirable that the plurality of red LEDs 112 display the magnitude of the combustion heating power (in other words, the heating amount) of the first cooking burner 10 by the number of lights of the red LEDs 112. The blue LED 114 may be omitted, and the red LED 112 may be turned on only when the first cooking burner 10 is in a combustion state.

In this pot detection heating function, when the cooking pot is not placed on the trivet 28, the first pot detecting means 58 does not detect the cooking pot, and in such a state, the combustion permission signal generating means 98 burns. It does not generate a permit signal and therefore the blue LED 114 of the first heating indicator means 32 is not lit.

In the above-described embodiment, when the first pot detecting means 58 detects the cooking pot, the blue LED 114 of the first heating display means 32 is lit and displayed. However, instead of such a configuration, the power switch 40 is used. The blue LED 114 may be turned on and displayed when it is turned on.

Next, a second embodiment of the built-in cooking cooker according to the present invention will be described with reference to FIGS. 4 and 5. In the second embodiment, a pseudo operation display unit that pseudo-displays input operation information is projected on the operation display unit, and the brightness of the pseudo operation display unit is adjusted according to the ambient brightness. It is configured to be. The basic configuration of this second embodiment is substantially the same as that of the first embodiment described above, and therefore, in the following description, a configuration different from that of the first embodiment will be described. In the following embodiments, substantially the same members as those in the first embodiment are designated by the same reference numbers, and the description thereof will be omitted.

With reference to FIGS. 4 and 5, in the gas cooker 2A of the second embodiment, in connection with the first burner detection means 42A (second and third burner detection means 44A, 46A), The operation information projection means 122 for displaying the input operation information in a pseudo manner is provided. The operation information projection means 122 includes the operation display information in the projected light from the laser light source 126 as the pseudo display light source and projects the operation display information onto the operation display area 66A, and projects in this way to display the pseudo operation as the input operation information. Project information.

The laser light source 126 of the operation information projection means 122 is composed of, for example, a red laser light source, and red laser light (that is, projected light) including operation display information is directed from the projection unit 124 toward the operation display area 66A of the kitchen counter 64. Be projected. When projected in this way, a pseudo operation display unit 68A (which functions as an operation display unit) is pseudo-provided in this operation display area 66A, and the projected pseudo operation display unit 68A is a pseudo stop display 72A as described above. Has (functions as a stop display), pseudo-down display 74A (functions as a down display), pseudo-up display 74A (functions as an up display), and pseudo-ignition display (pseudo-operation display) 78A (functions as an operation display). Then, when the operator controls the operation of the gas heating cooker 2A, a finger is positioned on the pseudo operation display unit 68A (pseudo stop display 72A, pseudo down display 74A, pseudo up display 76A, pseudo ignition display 78A) to perform a pseudo operation. Will be operated.

Further, the CCD sensor 56 passes the input image information from the pseudo operation display unit 68A (specifically, the image information including the position information of the finger located on the pseudo operation display unit 68A) through the light receiving unit 70A as described above. Upon receiving light, the light receiving signal processing means 88A of the controller 84A generates various operation signals in the same manner as described above based on the light receiving signal of the CCD sensor 56, and controls the operation of the gas heating cooker 2A.

For example, when the operator's finger is positioned on the pseudo ignition display 78A (or pseudo stop display 72A, pseudo down display 74A, pseudo up display 76A) of the pseudo operation display unit 68A of the kitchen counter 64 and a pseudo input operation is performed, the operation is performed. The discriminating means 90A discriminates as an ignition operation (or a stop operation, a down operation, an up operation) based on the position information of the finger, and the operation signal generating means 92A determines the operation content based on the above-mentioned discrimination result of the operation discriminating means 90A. The corresponding operation signal, that is, the ignition signal (or stop signal, down signal, up signal) is generated, and the control means 90 generates the ignition signal (or stop signal, down signal, up signal) generated by the operation signal generation means 92A. The operation of the first cooking burner 10 is controlled based on the above.

Further, the gas cooking cooker 2A of the second embodiment is equipped with a projected illuminance adjusting function for automatically adjusting the projected illuminance of the simulated operation display unit 68A. An illuminance detection sensor 126 (which constitutes an illuminance detection means) is arranged adjacent to the projection unit 124 of the stove body 4, and a detection signal from the illuminance detection sensor 124 is sent to the controller 84A. Further, in connection with the illuminance detection sensor 126, the controller 84A includes an illuminance determination means 128 and an illuminance adjustment signal generation means 130.

The illuminance detection sensor 126 receives light from the operation display area 66A of the kitchen counter 64 and its vicinity to detect the illuminance, and this illuminance detection signal is sent to the controller 84A. Further, the illuminance determination means 128 of the controller 84A determines the brightness of the operation display area 66A and its vicinity based on the illuminance detection signal from the illuminance detection sensor 126, and the illuminance adjustment signal generation means 130 determines the brightness of the illuminance detection sensor 126. When the detected illuminance is bright (or dark), an illuminance up signal (or illuminance down signal) is generated, and the control means 86A is based on the illuminance up signal (or illuminance down signal) of the laser light source 126 of the operation information projection means 122. By controlling to increase (or decrease) the output and adjusting the output of the laser light source 126 in this way, the pseudo operation display unit 68A is displayed as required regardless of the brightness of the operation display area 66A and its vicinity.
