Description

The present invention relates to a heating device. In particular, the present invention relates to an improvement of a setting display unit for setting and displaying the output of the 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 is provided with a heating unit such as a burner and a heating power setting unit consisting of an adjusting lever for setting the heating power or a rotor having a point fire extinguishing function and a heating power setting function. The thermal power is increased or decreased by moving the rotor 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 the setting position for obtaining a predetermined thermal power. Therefore, there is also known a heating cooker in which a display unit for displaying the current thermal power is provided on a top plate provided with a heating unit. If the cooking cooker has such a display unit, the user can change the heating power while observing the set heating power displayed on the display unit.

However, since these thermal power setting units are generally provided on the front panel of the heating cooker main body separated from the heating unit in consideration of the temperature during use, it is difficult for the user to see the installation location. In particular, when a user who is unfamiliar with the heating cooker operates a cooking cooker having a plurality of heating parts and having a heating power setting unit corresponding to each heating part, the heating power setting unit can be selected. The operability is inferior because there is a possibility of getting lost or operating the wrong heating power setting unit. Further, if the user is unfamiliar, even if the display unit currently displays the thermal power, it is difficult to determine how much the thermal power setting unit should be moved to obtain the predetermined thermal power.

The circuit configuration of the thermal power control unit that controls the thermal power of 12 and 13 and the automatic cooking control unit that executes automatic cooking, which is one of the automatic adjustment operations that automatically adjusts the thermal power based on predetermined predetermined conditions. Have.

Next, the control operation in the cooking 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. 5 to 6. The heating cooker of the present embodiment is always supplied with power, but when not in use, the setting display units 51, 52, and 53 are hidden in the low power mode or the sleep state, and the motion sensor 40 is used. When a human body is detected, it is configured to go from a low power mode or a sleep state to an operation standby state. Although the displayed images are slightly different between the setting display units 51 and 52 for the left and right stove burners 11 and 12 and the setting display unit 53 for the central stove burner 13, the display of the thermal power setting key and its operation Since all of them are the same, the case of cooking using the left stove burner 11 will be described below.

When the user approaches the cooker and the human body is detected by the motion 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). On the top menu screen of the heating cooker of the present embodiment, 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 the heating temperature, and an automatic setting for automatic cooking are displayed. The cooking setting key 58 and the transfer setting key 59 for downloading the 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.

Then, within a predetermined standby time (for example, 30 seconds), when the user performs an ignition operation of pressing the point fire extinguishing operation switch 71 without operating the automatic cooking setting key 58, the original gas valve Va and the electromagnetic valve When V1 is opened, the flow rate adjusting valve S1 is adjusted to a predetermined ignition opening degree (for example, the opening degree of low heat), and an ignition process is executed in which the igniter 80 is operated to generate a spark discharge from the ignition electrode 31. (Steps ST3 to ST6). At the time of this ignition operation, since the combustion flame is not detected by the flame detection sensor 21, the top menu screen is displayed on the color liquid crystal panel. If no operation is performed within the predetermined waiting time, the screen is erased (step ST20).

When the flame detection sensor 21 detects a combustion flame within a predetermined energization time (for example, 3 seconds) by the ignition process, the ignition detection screen is displayed (steps ST7 to ST9). On this ignition detection screen, a horizontally long bar-shaped heat setting key 61 including an operable pointer 62 rises from the front edge where the point fire 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. 5 (b)). The thermal power setting key 61 shown by the broken line in FIG. 5B indicates the middle of movement from the front. As a result, the user can recognize that the heat setting key 61 appears from the point fire extinguishing operation switch 71 operated by the user, and therefore is the setting key for the stove burner 11 to be used. Further, when the other stoves 12 and 13 are not used, the output setting key 61 is displayed only on the setting display unit 51 and not on the setting display units 52 and 53, so that the operation of changing the thermal power is not lost.

Further, on the ignition detection screen, when ignition is detected by the flame detection sensor 21, the background color of the color liquid crystal panel is displayed as a light red color of a warm color (FIG. 5B). As a result, the user can intuitively recognize that the stove burner 11 has been ignited by the color vision. Further, on the ignition detection screen, the character display 63 of the current thermal power (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). It is displayed (for seconds) (Fig. 5 (b)). As a result, even a user with color vision deficiency who cannot recognize red can reliably recognize ignition and current thermal power. The character display 63 may use alphabetic characters, numerical values, or the like. The character display 63 of the current thermal power is erased when the character display time elapses (steps ST10 to ST11, FIG. 5C). As a result, the number of images on the setting display unit 51 is reduced, and a neat screen is formed.

Although not shown, when a combustion flame is not detected by the flame detection sensor 21 within a predetermined energization time, the character display of "ignition error" is displayed at the center of the front, rear, left and right of the color liquid crystal panel (step ST12).

Next, when the user slides the pointer 62 of the thermal power setting key 61 to the left or right with his / her finger on the pointer 62 to change the thermal power, or touches a predetermined position on the thermal power setting key 61 to move the pointer 62. 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 the color liquid crystal panel displays a screen when the thermal power is changed (steps ST13 to ST14, FIG. 6D). In this way, since the pointer 62 that can be operated is provided on the thermal power setting key 61 that is displayed in animation on the setting display unit 51 by the ignition operation of the user, the thermal power can be changed by intuitively operating the pointer 62. Can be recognized as.

Further, when the user operates the thermal power setting key 61, the background color of the color liquid crystal panel on the screen at the time of changing the thermal power is changed in shade according to the set thermal power (FIG. 6 (d)). Specifically, as the thermal power increases, the background color is changed so that it becomes a deep red color, and as the thermal power decreases, the background color is changed so that it becomes a light red color. That is, the background color of the color liquid crystal panel and the thermal power generated by operating the touch panel are configured to be synchronized. As a result, the user can intuitively recognize the increase or decrease of the thermal power by the color vision from the setting display unit 51.

Further, on the screen at the time of changing the thermal power, while the user is operating the pointer 62, the character display 63 of the current thermal power is redisplayed, and the character display 63 according to the set thermal power (for example, the character of "high heat") is displayed. A balloon image including the display) is displayed above the thermal power setting key 61 (FIG. 6 (d)). As a result, even a user with color vision deficiency who cannot recognize red can surely recognize the current thermal power. When the user releases the pointer 62 and the predetermined character display time elapses, the character display 63 of the current thermal power 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 solenoid valve V1 are closed, and when the stove burner 11 extinguishes the fire, The background color of the color liquid crystal panel is returned to white, and the character display 65 at the time of extinguishing (for example, the character display of "fire extinguished") is displayed (step ST18, FIG. 6 (f)). Then, when the predetermined character display time (for example, 5 seconds) has elapsed (Yes in step ST19), the screen returns to the top menu screen (FIG. 5A). After the fire extinguishing operation, if the human body is not detected by the motion sensor 40 within the standby time and none of the point fire extinguishing operation switches 71, 72, 73 is operated, the setting display units 51, 52, 53 are hidden. Return to the low power mode or sleep state (step ST20).

Further, although not shown, when the user selects automatic cooking with the automatic cooking setting key 58 before operating the point fire extinguishing operation switch 71, the heating power setting key 61 can be selected by automatic cooking without being displayed in animation. A cooking setting key displaying various cooking names and pictures of dishes appears, and an automatic cooking program corresponding to the type of cooking to be selected is started (step ST21). As a result, it is possible to prevent a change in heating power due to an erroneous operation during automatic cooking. Even when automatic cooking is selected, the heating power setting key 61 may be displayed after ignition is detected. In this case, by disabling the operation of the thermal power setting key 61, erroneous operation can be similarly prevented.
