A grill display means 90 is provided above the down switch 86 and the up switch 88. The magnitude of the combustion thermal power of the burner 16 is displayed.

  In the gas cooking stove 2, the reflected laser beam information obtained by the first burner operation detection means 36 (second and third burner operation detection means 38, 40) of the operation detection means 32, that is, the operation obtained by the CCD sensor 46. The information signal is processed by the control system shown in FIG. Referring mainly to FIG. 4, the gas cooking stove 2 includes a controller 92 composed of, for example, a microprocessor. The controller 92 includes a light reception signal processing means 94, an operation determination means 96, an operation signal generation means 98, and Including the operation control means 100, the received light signal processing means 94, the operation determination means 96, and the operation signal generation means 98 constitute a part of the operation detection means 32.

  The received light signal processing means 94 processes the received light signal (reflected laser light signal) generated by the CCD sensor 46 of the first burner operation detecting means 36 (second and third burner operation detecting means 38, 40) as required. Then, the operation determination unit 96 determines the input operation content in the operation display unit 42 based on the processing signal processed by the received light signal processing unit 94. That is, the operation determination unit 96 identifies the position of the operator's finger F from the reflected laser beam information as the reflected electromagnetic wave information related to the operation display unit 42, and the input operation of the operation display unit 42 is performed based on the position of the finger F. Determine the contents. For example, when the finger F is positioned on the ignition display 62 (or the stop display 56, the down display 58, and the up display 60), the operation determination unit 96 determines the ignition operation (or stop operation, down operation, Up operation).

  Further, the operation signal generation means 98 corresponds to the input operation content in the first burner operation detection means 36 (second and third burner operation detection means 38, 40) based on the determination input operation determined by the operation determination means 96. An operation signal is generated, and the operation control unit 100 controls the operation of the first cooking burner 10 (second and third cooking burners 12 and 14) based on the operation signal generated by the operation signal generation unit 98. For example, when the operation determination unit 96 determines that the ignition operation (or stop operation, down operation, up operation) is performed, the operation signal generation unit 98 generates an ignition signal (or stop signal, down signal, up signal) based on the determination result. Then, the operation control means 100 ignites and burns the first cooking burner 10 (second and third cooking burners 12, 14) based on this ignition signal (stop signal, up signal, down signal). Ascend, stop burning).

  Next, the operation of the gas cooking stove 2 described above will be described mainly with reference to FIGS. 2, 3 and 4. Hereinafter, although the operation by the 1st cooking burner 10 is demonstrated, the operation of the 2nd and 3rd cooking burners 12 and 14 is also the same, Therefore, description about these operation is abbreviate | omitted.

  In order to operate the first cooking burner 10, the finger F may be positioned on, for example, the ignition display 62 (or the stop display 56, the down display 58, and the up display 60) of the operation display unit 42 of the kitchen counter 50. Thus, the infrared laser light projected from the light projecting unit 64 is reflected by the finger F and received by the light receiving unit 66, and reflected laser light (reflected laser beam information) including positional information on the position of the finger F is obtained. The light is transmitted to the CCD sensor 46 through the light receiving unit 66 and the second transmission fiber 70.

  When the reflected laser light is sent to the CCD sensor 46 in this way, the CCD sensor 46 generates a light reception signal corresponding to the position information of the finger F, and this light reception signal is sent to the controller 92. Then, the light reception signal processing means 94 processes this light reception signal as required, and the operation determination means 96 identifies the position of the finger F based on the processing signal from the light reception signal processing means 94 as described above. The input operation content is determined based on this position information. For example, when the finger F is positioned on the ignition display 62 of the operation display unit 42, it is determined from the position information of the finger F that the ignition operation is performed.

  The operation signal generation means 98 generates an operation signal corresponding to the input operation content, that is, an ignition signal based on the discrimination of the ignition operation, and the operation control means 100 converts the ignition signal generated by the operation signal generation means 98 into the ignition signal. Based on this, the first cooking burner 10 is ignited and burned.

  For example, when the ignition signal is generated, the on-off valve 20 is opened, and the ignition means 22 is operated to ignite and burn the combustion burner 18. For example, when a stop signal is generated, the on-off valve 20 is closed, and the combustion of the combustion burner 18 is completed. Further, when the down signal (or up signal) is generated, the flow control valve 22 is controlled to reduce the flow rate (or increase the flow rate), and the combustion thermal power of the combustion burner 18 becomes weak (or strong).

  For example, in the above-described embodiment, the first transmission fiber 68 is used to guide the infrared laser light from the laser light source 44 to the light projecting unit 64, and the reflected laser beam (reflected laser beam information) received by the light receiving unit 66. The second transmission fiber 70 is used to guide the light to the CCD sensor 46. However, the first and second transmission fibers 68 and 70 may be omitted as shown in FIG.

  5, in this modification, a laser light source 44 is provided in the light projecting unit 64, a CCD sensor 46 is provided in the light receiving unit 66, and infrared laser light from the light projecting unit 64 is related to the operation display unit 42. In other words, the reflected laser beam (reflected laser beam information) related to the operation display unit 42 is projected to the CCD sensor 46 through the light receiving unit 66. Received light.

  In this connection, the laser light source 44 and the CCD sensor 46 are configured as a light projecting / receiving unit 112, and the light receiving / receiving unit 112 is disposed inside the protective cover 72. In addition, the controller 92A and the light receiving / receiving unit 112 are electrically connected via the lead wire 114, and the light projection signal from the controller 92A is sent to the laser light source 44 via the lead wire 114, and the CCD sensor 46 is also connected. The light reception signal from the signal is sent to the controller 92A via the lead wire 114. The received light signal sent to the controller 92A is processed as described above. Therefore, even with this configuration, the same operational effects as described above are achieved.

  In the above-described embodiment, the operation display for displaying the input operation information of the first burner operation detection means 36 (or the second burner operation detection means 38 and the third burner operation detection means 40) in the operation display area 48 of the kitchen counter. Although the unit 42 is provided, instead of such a configuration, a pseudo operation display unit that displays input operation information in a pseudo manner on the operation display area 48 of the kitchen counter 50 may be projected. In the following other embodiments, members that are substantially the same as those in the above-described embodiment are given the same reference numerals, and descriptions thereof are omitted.

  6 to 8, in another embodiment, a light projecting unit is provided at a predetermined portion (specifically, a portion close to the operation display area 48B) on the front surface (front side surface) of the top plate 6B of the stove body 4B. In addition to 64B and the light receiving unit 66B, a projection unit 122 is provided, and the pseudo operation display unit 42B is projected from the projection unit 122. More specifically, the first burner operation detection unit 36B (second burner operation detection unit 38B, third burner operation unit 40B) of the operation detection unit 32B (see FIG. 8) is a laser light source 44 (which constitutes an electromagnetic wave output unit). In addition to the CCD sensor 46 (which constitutes the electromagnetic wave information acquisition means), a pseudo display means 124 is included, and the pseudo display means 124 includes operation display information in projection light from a pseudo display light source (not shown). Projection is performed on the operation display area 48B, and projection is performed in this way to project pseudo operation display information as input operation information.

  As a pseudo display light source (not shown) of the pseudo display unit 104, for example, a red laser light source is used, and red laser light (that is, projection light) including operation display information is displayed from the projection unit 122 to the operation display area of the kitchen counter 50. Projected toward 48B. When projected, the operation display area 48B is provided with a pseudo operation display unit 42B in a pseudo manner as shown in FIGS. 6 and 7, and the projected pseudo operation display unit 42B is simulated as described above. A stop display 56B, a pseudo down display 58B, a pseudo up display 60B, and a pseudo ignition display 62B are provided. When the operator controls the operation of the gas cooking stove, the pseudo operation display unit 42B (a pseudo stop display 56B, a pseudo down display 58B). Then, the finger F is positioned on the pseudo up display 60B and the pseudo ignition display 62B), and the pseudo operation is performed. Further, the CCD sensor 46 transmits the reflected laser light related to the pseudo operation display unit 42B (specifically, the reflected laser light from the finger F positioned on the pseudo operation display unit 42B) through the light receiving unit 66B as described above. Based on the light reception signal of the CCD sensor 46, the controller 92B generates an operation signal and controls the operation of the gas cooking stove in the same manner as described above.

  For example, when a finger is positioned on the pseudo ignition display 62B (or pseudo stop display 56B, pseudo down display 58B, pseudo up display 60B) of the pseudo operation display unit 42B of the kitchen counter 50, the finger is reflected by the finger. The input operation content is identified from the reflected laser beam (reflected laser beam information), and the operation determination unit 96 determines the ignition operation (or stop operation, down operation, up operation) as described above, and the operation signal generation unit 98.
