Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to an electronic device having a designation ttlftB.

<Prior art> Conventionally, when demonstrating electrical equipment at a store, for example, it was necessary to demonstrate by actually operating the equipment;
Or special signs were set up for demonstration purposes. 1. This had the disadvantage that it took time to perform and prepare.

In view of the above, the present invention aims to reduce the time required for demonstrations by automatically and continuously displaying only the TA function on the display section of the main body of the instrument, in addition to the display of the normal operating state. The purpose is to provide electronic equipment that is functional and easy to operate.

<Example> Hereinafter, an example in which the present invention is applied to a glossy rice cooker will be explained based on the drawings. The display unit 2 is provided with an operation control circuit 3 that outputs an operation status signal, and a defeat display circuit 4 that outputs a status display signal, and either of the operation control circuit 3 or the +fuf!hi display circuit/1 is provided. A switching means 5 is provided for switching to operate one of the two.

In addition, when the operation control circuit 3 is in its power-on state, the operation key 7
Preheating operation to maintain the temperature at around 45 degrees Celsius with the following operations, rice cooking operation to heat the rice to the finished temperature, additional cooking operation to adjust the unevenness and burntness, and 7 (to keep the temperature at around 1'C) It is configured to control the output section (heater) 8 so as to sequentially perform the heat retention operation, and the operation status!'A
'HFi number is output to the display section 2.

The display section 2 includes a preheating lamp 9, a rice cooking lamp 10, a heat retention lamp 11, a rice cooking start lamp 12, and a strong burn lamp 1.
3 and a low-dark lamp 14, and these lamps 9 to 14
is turned on, turned off, or blinks in response to signals from the operation control circuit 3 and (skill display circuit 4). Figures 11 (a) to (d) show the display section when normal operation is activated 5(a) to 5(d) show the display state of the display unit 2 during the demonstration. In Fig. 1, the solid line display is in the lamp display state. A lit and dotted line display indicates an extinguished moon, and a black half-moon display indicates a blinking state.

In addition, the function display circuit 11 patterns the function displays of preheating, rice cooking, additional cooking, storage 1, strength and weakness into four types as shown in Table 1, and displays the display signals of these display patterns No. \ to D on the display section. It is configured to output to 2.

In Table 1, ○ means the light is on, △ means the light is blinking, and × means the light is off.

Table-! - Furthermore, the switching means 5 comprises a changeover switch 15 which is provided as a hidden function as shown in FIG. and selector switch 1
A control section 17 including a circuit for determining whether 5 is in the on state or not] 6, an operation control circuit 3 activated by a signal from the determination circuit, and a function display circuit 11 is a microprocessor (]=ST) 1H. Built-in.

Next, the effect will be explained. As shown in FIG. 3, when the power source 6 is in the on state, it is determined whether the changeover switch 15 is in the on state or not. This control primarily uses a heater to preheat the rice, maintain the temperature inside the pot at around 45°C, and allow moisture to penetrate into the rice. Next, heat the rice until it reaches a temperature of 1 kettle and finish cooking. Then, start additional cooking mode and adjust for unevenness and burnt rice. Also, keep warm mode as appropriate to raise the temperature inside the pot to 70'C. The rice is kept at the highest temperature by keeping the rice at the highest temperature.Indications from preheating to keeping warm are displayed on the display.

Further, when the changeover switch 15 is in the on state, the operation control circuit 3 does not operate, and only the function display circuit 1 operates.
The display patterns A to D shown in FIG. 2 are repeated at 5 second intervals, and the lamps 9 to 1) of the display section 2 are turned on or blinked.

Note that the display patterns A to D do not necessarily have to be continuous in a loop as shown in Figure 2, but if a service person or a purchaser uses them for confirmation, it is better to program them to be displayed each time.・.

You may also add a function that plays a sound every time the display status changes (4).

In the present invention, the switching means 5 may be composed of several types of operation keys 7 instead of the changeover switch 15 provided as a hidden +1fiu as in this example. That is, it may be configured such that when several keys 7 are pressed at the same time and the power supply 6 is turned on, the operation control circuit 3 is switched to the function display circuit 4.

FIG. 7 shows an embodiment of a microwave oven in which the present invention is applied to a microwave oven, and the display section 2 displays messages such as "Jin Ito", "Grill", "Please heat", and "-Completed". A display is provided, and each time the display changes, a display lamp is lit and a buzzer or the like is generated to turn off the display. In this case, display can be easily performed by using a speech synthesis microprocessor (L, Sl).

<Effects> As is clear from the above description, the present invention includes an operation control circuit that outputs an operation status signal to a display section provided on the main tree of the defeater during normal operation, and a function display section on the display section. A function display circuit for outputting a signal is provided, and a switching means is provided for activating either the operation control circuit or the function display circuit.

Therefore, according to the present invention, for example, in a demonstration at a store, it is possible to provide an electric/monthly billing device that can automatically and continuously display only the function information and is easy to operate.
