【Example】
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0016]
(Example 1)
FIG. 1 shows a multi-port induction heating cooker according to a first embodiment of the present invention.
[0017]
In the figure, 1 is a commercial power supply, 2 is a power switch for turning on / off the power of the equipment, 3a and 3b are induction heating means, respectively, diode bridges 4a and 4b, heating coils 5a and 5b, resonance capacitors 6a and 6b, respectively. It is composed of switching elements 7a and 7b. 8a and 8b are control means for controlling the heating by the induction heating means 3a and 3b, 9 is a power supply voltage detecting means for detecting the power supply voltage of the equipment, 10 is an operating means for turning on / off the heating and adjusting the heating power, and 11 is Demonstration setting means for setting a demo mode different from the normal operation, 12 is a notifying means for receiving an operation by the operating means 10 or notifying an abnormality, and 13 is an operation state of the equipment, that is, heating of the induction heating means 3a or 3b. Display means for displaying the status.
[0018]
In the induction heating cooker configured as described above, the power supply voltage detection means 9 is a low power supply that does not normally operate the appliance and is detected at a predetermined voltage or more, that is, for example, when the normal commercial power supply is not 200 V but for example, When it is detected that the power supply voltage is connected to the 100 V power supply, the display means 13 indicates that the power supply voltage is abnormal, so that the heating operation by the operation means 10 cannot be performed. In such a case, when the demonstration mode is set by the demonstration setting means 11, the power supply voltage abnormal display on the display means 13 is stopped, and the same display as in the state where the normal power supply voltage (200 V) is supplied is provided. Do.
[0019]
Further, when a heating operation is performed by the operating means 10, the operating means 10 sends a heating prohibition signal to the control means 8a or 8b, and sends the same signal to the notification means 12 and the display means 13 as usual. The device can be operated as if it were not heated, but as if it were heated. As a result, even in a place such as a store where only a general 100 V power supply is available, it is possible to experience the operability and operating state of the product. Further, since the demonstration setting is intentionally performed, the device cannot be heated without knowing that the demonstration is performed, and the device is not mistaken for a failure.
[0020]
Since the demonstration setting means 11 is not necessary as a device in a general household, for example, the demonstration setting can be performed when a predetermined three of a plurality of operation switches in the operation means 10 are simultaneously pressed. This can be realized without increasing the number of meaningless switches. The number of induction heating cookers is not limited to two, and the present invention can be applied to those having more than one or single mouth.
[0021]
(Example 2)
Next, FIG. 2 shows a multi-port induction heating cooker according to a second embodiment of the present invention.
[0022]
This embodiment is different from the first embodiment in that a storage unit 14 for storing a demonstration setting when a demonstration state is set by the demonstration setting unit 11 is added. Others are the same, and the description is omitted.
[0023]
The storage means 14 is a non-volatile memory. The demonstration setting unit 11 writes the state into the storage unit 14 when entering the demo mode and when canceling the demo mode. Thus, once the demo mode is set during the demonstration at the store or the like, even if the power switch 2 is turned off or the breaker of the power supply is turned off, the demo mode is not set again by the demo setting means 11 and the demo mode is set. Can be transferred to.
[0024]
Further, immediately after turning on the power to the device or when the power switch 2 is turned on, if the power supply voltage detecting means 9 detects that the power supply voltage is 100 V, the display means 13 displays an abnormality display for a predetermined time (for example, one minute). After that, if the demonstration setting is stored in the storage means 14, the abnormal display is stopped and the mode shifts to the demonstration mode. If the demonstration setting is not stored, the abnormal display is continuously displayed. Thus, even if a demonstration item such as an exhibit is installed by mistake, it can be understood that the device is not at fault when the power supply voltage is 100 V.
[0025]
When the power supply voltage detecting means 9 detects that the power supply voltage is 200 V, the demonstration setting in the storage means 14 is cleared and the demonstration setting is released. As a result, even if a demonstration-set item such as an exhibit is installed by mistake, the demonstration setting can be canceled and returned to a normal state.
[0026]
(Example 3)
Next, FIG. 3 shows an operation unit of a multi-port induction heating cooker according to a third embodiment of the present invention.
[0027]
The operation unit according to the present embodiment includes the operation unit 10 and the display unit 13 according to the first and second embodiments. As shown in the figure, there are a timer setting switch 15 for setting a timer and an automatic cooking switch 16 for setting temperature adjustment of fried foods, etc., and has an automatic cooking function or a timer cooking function. Here, in the demonstration of the automatic cooking or the timer cooking operation, the time count is performed at a count faster than the normal count. That is, when the timer setting is set to 15 minutes by the timer setting switch 15 in the demo mode, the operation is performed at 60 times, that is, 1 minute = 1 second. As a result, the 15-minute setting is completed in 15 seconds, and the notification sound and display at the end of the timer can be shown quickly.
[0028]
In the case of automatic cooking, not only the time but also the temperature change by the temperature detecting means (not shown) is actually involved in the progress. Therefore, even if the heating is not actually performed, the process changes (before preheating and after preheating) are sequentially performed. The display allows the explanation to be made in a short time.
[0029]
Although not shown, special demo setting means for performing special demo settings different from the demo setting means during the demonstration operation is provided. If the special demo setting is performed, an error code or the like which can be displayed by the device is provided. The abnormal state is displayed by displaying the abnormal display in order or displaying a display form in the case of a combined occurrence. As a result, a serviceman or the like performing repair or the like can understand in advance.
[0030]
【The invention's effect】
