Description

  The present invention relates to a heating device. In particular, the present invention relates to an improvement of a setting display unit that sets and displays the output of a heating unit in a heating device.

  Conventionally, a heating device having a heating unit and an output setting unit for setting the output of the heating unit is known. For example, a heating cooker includes a heating unit such as a burner and a heating power setting adjustment lever or a heating power setting unit including a rotor that has both a fire extinguishing and a heating power setting function. The heating power is increased or decreased by moving or rotating the rotor in the forward or reverse direction.

  By the way, since the thermal power setting unit as described above is a physical switch, it is difficult for the user to determine a setting position for obtaining a predetermined thermal power. Therefore, a cooking device is also known in which a display unit for displaying the current heating power is provided on a top plate provided with a heating unit. If it is a heating cooker which has such a display part, the user can change a thermal power, seeing the setting thermal power displayed on a display part.

  However, these thermal power setting units are generally provided on the front panel of the main body of the heating cooker separated from the heating unit in consideration of the temperature during use, so that the installation location is difficult for the user to see. In particular, when a user who is unfamiliar with the heating cooker has a plurality of heating units and has a heating power setting unit corresponding to each heating unit, select the heating power setting unit. There is a possibility that the user may get lost or operate an incorrect thermal power setting unit, which is inferior in operability. In addition, if the user is unfamiliar, it is difficult to determine how much the predetermined thermal power can be obtained by moving the thermal power setting unit even if the thermal power is currently displayed on the display unit.

As the touch panel, for example, a resistive film type, surface acoustic wave type, infrared optical imaging type, electromagnetic induction type touch panel, or the like may be used.

  FIG. 2 is a block diagram of the cooking device. As shown in FIG. 2, gas supply pipes L 1, L 2, and L 3 that guide the gas supplied from the main gas supply pipe L to the respective burners 11, 12, and 13 are disposed in the heating cooker body. . The main gas supply pipe L is provided with an original gas valve Va that opens when an ignition operation is performed by the point fire extinguishing operation switches 71, 72, and 73 and closes when the fire extinguishing operation is performed. Further, the gas supply pipes L1, L2, and L3 branched from the main gas supply pipe L to the respective burners 11, 12, and 13 are opened when an ignition operation is performed by the point fire extinguishing operation switches 71, 72, and 73, and the flames are opened. Solenoid valves V1, V2, and V3 that close if detection flames are not detected by detection sensors 21, 22, and 23, and flow rate adjustment valves S1, S2, and S3 that are adjusted in accordance with an instruction signal from controller C are provided. It is installed.

  The control device C that controls the operation of the whole cooking device includes point-extinguishing operation switches 71, 72, 73, human sensor 40, flame detection sensors 21, 22, 23, pan bottom temperature sensors 41, 42, 43, and setting display. The parts 51, 52, 53, the igniter 80, the original gas valve Va, the electromagnetic valves V1, V2, V3, the flow rate adjusting valves S1, S2, S3, and the like are connected by wire, and the above-described point fire extinguishing operation switches 71, 72, 73, etc. Operation signals and detection signals from various sensors 21, 22, 23, 40, 41, 42, 43, and the like.

  The control device C is an electronic unit that includes a microcomputer and a storage device.

Moreover, although not shown in figure, the control apparatus C is a point fire extinguishing control part which performs ignition and fire extinguishing of the burners 11, 12, and 13, a point fire extinguishing judgment part which judges ignition and fire extinguishing of the stove burners 11, 12, 13 and setting display. In accordance with the operation of the heating power setting keys of the control burners 11, 12, 13 displayed on the setting display units 51, 52, 53, which will be described later, the display control unit for controlling the display of the units 51, 52, 53. Circuit configurations of a thermal power control unit that controls the thermal power of 12, 13 and an automatic cooking control unit that executes automatic cooking that is one of automatic adjustment operations that automatically adjust the thermal power based on a predetermined condition. Have.

  Next, the control operation in the heating cooker of the present embodiment will be specifically described with reference to the flowcharts of FIGS. 3 to 4 and the display screen of the setting display unit of FIGS. The cooking device of the present embodiment is always supplied with power, but when not in use, the setting display sections 51, 52, and 53 are not displayed in the low power mode or the sleep state. When a human body is detected, it is configured to enter a standby state from a low power mode or a sleep state. Although the displayed images are slightly different between the setting display sections 51 and 52 for the left and right conburners 11 and 12 and the setting display section 53 for the central burner 13, the display and operation of the heating power setting key are different. Since both are the same, the case where cooking is performed using the left stove burner 11 will be described below.

  When the user approaches the cooking device and a human body is detected by the human sensor 40, the main control program of the control device C is activated, and a predetermined top menu screen (pre-ignition screen) is displayed on the color liquid crystal panel of the setting display unit 51. Is displayed to enter the operation standby state (steps ST1 to ST2, FIG. 5A). The top menu screen in the heating cooker of the present embodiment has a water heater setting key 55 for boiling water, a timer setting key 56 for executing timer cooking, a temperature setting key 57 for setting a heating temperature, and an automatic setting for automatic cooking. A cooking setting key 58 and a transfer setting key 59 for downloading a cooking recipe from an information terminal such as a mobile phone are displayed. At this time, the background color of the color liquid crystal panel in the operation standby state is displayed in white.

  Next, when the user performs an ignition operation for pressing the fire extinguishing operation switch 71 without operating the automatic cooking setting key 58 within a predetermined standby time (for example, 30 seconds), the original gas valve Va and the electromagnetic valve While V1 is opened, the flow rate adjusting valve S1 is adjusted to a predetermined ignition opening (for example, a low-fire opening), and an ignition process is performed in which the igniter 80 is operated to generate a spark discharge from the ignition electrode 31. (Steps ST3 to ST6). During this ignition operation, no flame is detected by the flame detection sensor 21, so that a top menu screen is displayed on the color liquid crystal panel. If no operation is performed within a predetermined waiting time, the screen is erased (step ST20).

  If the flame detection sensor 21 detects a combustion flame within a predetermined energization time (for example, 3 seconds) by the ignition process, an ignition detection screen is displayed (steps ST7 to ST9). On the ignition detection screen, a horizontally long bar-shaped heating power setting key 61 including an operable pointer 62 rises from the front edge where the point extinguishing operation switch 71 is provided on the color liquid crystal panel toward the center in the front-rear direction. It is displayed as an animation (FIG. 5B). In addition, the thermal power setting key 61 shown with the broken line in FIG.5 (b) shows the middle of the movement from the front. As a result, the user can recognize that the firepower setting key 61 appears from the point-extinguishing operation switch 71 operated by the user, and is therefore a setting key for the combustor 11 to be used. Further, when the other burners 12 and 13 are not used, the output setting key 61 is displayed only on the setting display section 51 and is not displayed on the setting display sections 52 and 53, so that the user does not hesitate to change the heating power.

  On the ignition detection screen, when the flame detection sensor 21 detects ignition, the background color of the color liquid crystal panel is displayed in a warm red light color (FIG. 5B). As a result, the user can intuitively recognize that the burner 11 has been ignited by color vision. Further, on the ignition detection screen, the current thermal power character display 63 (for example, a balloon image including the character display of “low heat”) is displayed above the pointer 62 of the thermal power setting key 61 for a predetermined character display time (for example, 3 Seconds) (FIG. 5B). As a result, even a user with color blindness who cannot recognize red color can reliably recognize the ignition and the current thermal power. The character display 63 may use English letters, numerical values, or the like. The character display 63 of the present thermal power is erased when the character display time has elapsed (steps ST10 to ST11, FIG. 5C). As a result, the number of images on the setting display section 51 is reduced, and a clean screen is formed.

  Although not shown, when no flame is detected by the flame detection sensor 21 within a predetermined energization time, a character display of “ignition error” is displayed at the front, rear, left and right central portions of the color liquid crystal panel (step ST12).

  Next, when the user moves the pointer 62 by sliding left or right with the finger placed on the pointer 62 of the thermal power setting key 61 or touching a predetermined position on the thermal power setting key 61 to change the thermal power. The opening degree of the flow rate adjusting valve S1 is changed depending on the position of the pointer 62 to increase or decrease the thermal power, and a thermal power change screen is displayed on the color liquid crystal panel (steps ST13 to ST14, FIG. 6D). As described above, since the pointer 62 that can be operated is provided on the heating power setting key 61 that is displayed on the setting display unit 51 as an animation by the user's ignition operation, the heating power can be changed by operating the pointer 62 intuitively. Can be recognized.

  Further, the background color of the color liquid crystal panel on the screen at the time of changing the thermal power is changed depending on the set thermal power when the user operates the thermal power setting key 61 (FIG. 6D). Specifically, the background color is changed so as to become dark red as the thermal power becomes larger, and the background color is changed so as to become light red as the thermal power becomes smaller. That is, the background color of the color liquid crystal panel and the thermal power generated by the operation of the touch panel are synchronized. Thereby, the user can intuitively recognize the increase / decrease of the thermal power by the color vision from the setting display unit 51.

  Further, while the user is operating the pointer 62 on this heating power change screen, the character display 63 of the current heating power is displayed again, and the character display 63 corresponding to the set heating power (for example, a character of “high fire”). A balloon image including a display) is displayed above the heating power setting key 61 (FIG. 6D). Thereby, even a user with color blindness who cannot recognize red can reliably recognize the current thermal power. When the user releases the pointer 62 and a predetermined character display time elapses, the current heat character display 63 is erased in the same manner as described above while maintaining the background color (steps ST15 to ST15). ST16, FIG. 6 (e)).

  When cooking is completed and the user performs a fire extinguishing operation by pressing the point fire extinguishing operation switch 71 (Yes in step ST17), the original gas valve Va and the electromagnetic valve V1 are closed, and the stove burner 11 is extinguished. The background color of the color liquid crystal panel is returned to white, and the character display 65 at the time of fire extinguishing (for example, the character display of “fire extinguished”) is displayed (step ST18, FIG. 6 (f)). When a predetermined character display time (for example, 5 seconds) elapses (Yes in step ST19), the screen returns to the top menu screen (FIG. 5A). After the fire extinguishing operation, if no human body is detected by the human sensor 40 within the standby time, and none of the point fire extinguishing operation switches 71, 72, 73 is operated, the setting display sections 51, 52, 53 are not displayed. It returns to the low power mode or sleep state to become (step ST20).

  Although not shown, when the user selects automatic cooking with the automatic cooking setting key 58 before operating the fire extinguishing operation switch 71, the heating power setting key 61 can be selected by automatic cooking without being displayed as an animation. A cooking setting key on which a name of a dish, a picture of the dish, etc. are displayed appears, and an automatic cooking program corresponding to the type of cooking to be selected is started (step ST21). Thereby, the thermal power change by the erroneous operation during automatic cooking can be prevented. Even when automatic cooking is selected, the heating power setting key 61 may be displayed after the ignition is detected. In this case, erroneous operation can be similarly prevented by disabling the operation of the heating power setting key 61.
