Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a time setting method for a cooker having a timer that reserves a cooking completion time for a jar rice cooker, an automatic bread maker, an oven, etc. used in a general household. Is.

2. Description of the Related Art Conventionally, in this type of cooker, an operation part substrate 2 and a control substrate 3 are provided in a main body 1 like the example of the jar rice cooker shown in FIGS. And the liquid crystal display element 5, the light emitting diode 6, and the tact switch 7 are mounted on the operation unit substrate 2, and the operation unit is the fourth unit.
The liquid crystal display element 5 is arranged as shown in the figure, and the liquid crystal display element 5 further includes a time display section for alternately displaying reserved time and current time,
Menu display part such as "white rice""brownrice""porridge",
It was provided with a process display section such as "front cooking", "cooking up", "additional cooking".

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, in such a conventional cooking device, when trying to set the time, the "hour" key and the "minute" key are used to count up by 1 for setting. It takes time and effort to establish from "00" to "59"
It was difficult to match. Further, if the number keys of "0 to 9" are provided, it is easy to set, but it is necessary to cover 10 switches, which makes the operation unit look complicated.

The present invention solves such a problem, and provides a time setting method for a cooker that can make the entire operation unit compact without increasing the number of switches of the operation unit and making the operation unit complicated. The purpose is to do.

Means for Solving the Problems In order to solve the above-mentioned problems, the time setting method of the cooking device according to the present invention is configured such that the time setting key is operated to set the time and the transparent touch switch has a switch part. Display a plurality of number keys for time setting at the rear, operate the switch section to set the time, erase the display of the number key after setting the time, and display the time at the display position of the number key I decided to do it.

Operation According to the above configuration, the switch portion of the transparent touch switch is provided on the front surface of the display element, and the position of the plurality of numeric keys for time setting can be displayed on the display element, thereby facilitating the time setting and the like. For this reason, even if the number of switches on the operation unit is increased and a numeric key for setting the time is provided, the display of the switch can be turned off when the time is set, which makes the operation unit complicated. And the display element can be made compact. As described above, it is possible to provide a compact cooking device display device having a simple structure, excellent operability, and easy to use.

Embodiment One embodiment of the present invention will be described below with reference to FIGS. 1 to 5.

It is composed of a part 5d that displays the menu of "porridge" and the process of "preparing / cooking / purple" .The part 5b that displays the reservation time is "4,5,6" of "0-9". ”
6a, 6b, 6c arranged so that parts can be displayed
Is a light emitting diode for displaying rice cooking and heat retention, respectively. Reference numeral 8 denotes a transparent, film-shaped touch switch arranged on the front surface of the liquid crystal display element 5, and constitutes a switch portion where a frame is written. 7a, 7b, 7c, 7d
Are a time setting key, a rice cooking key, a heat retention key, and a cancel key, respectively.

FIG. 3 is a circuit diagram of a rice cooker according to an embodiment of the present invention.
Is a liquid crystal display element, 6 is a light emitting display element for displaying a timer, rice cooking, and heat retention, and includes a timer light emitting diode 6a, a rice cooking light emitting diode 6b, a heat retaining light emitting diode 6c, and current limiting resistors 6d, 6e, 6f, The light emission is controlled by the microcomputer 9. 7a, 7b, 7c, 7
Reference characters d are a time setting key, a rice cooking key, a heat retention key, and a cancel key, respectively, which are connected to the microcomputer 9 so that signals can be input. Reference numeral 8 denotes a transparent touch switch, which is arranged in front of the liquid crystal display element 5. Reference numeral 10 denotes a liquid crystal display drive circuit, which is a circuit for driving the liquid crystal display element 5, and is controlled by the microcomputer 9. 11
Is an AC power supply, and 12 is a DC power supply circuit for converting the AC power supply 11 into a DC power supply. Reference numeral 13 denotes a load drive circuit, which is controlled by the microcomputer 9 and performs a rice cooking operation.

Next, the display and operation of the rice cooker configured as described above will be described with reference to FIGS. FIG. 2 shows a liquid crystal display element 5.
Shows the display state of. FIG. 2A shows the time of cooking rice with white rice, and when the rice cooking key 7b is pressed, this state is brought about, and the current time, the menu "white rice" and the process "pre-cooking" are displayed.

Explaining with reference to FIG. 4, when the rice cooking key 7b is pressed in step 20, the microcomputer 9 inputs this and controls the liquid crystal display drive circuit 10 in step 21 to turn on the liquid crystal display element 5. As shown in FIG. 2 (a), in step 22, the microcomputer 9 turns on the light emitting diode 6b and controls the load drive circuit 13 to perform the rice cooking operation.

FIG. 2b shows the time when the reserved time is adjusted. When the time adjustment key is pressed, this state is brought about, and the portion 5 for displaying the current time
The reserved time is displayed with a, and the reserved time is displayed with 5b.
"4, 5, 6" is displayed, and the positions of the numeric keys "0 to 9" and the positions of the "hour, minute" keys are displayed. When changing the reservation time, for example, when it is set to "8:30",
By pressing the keys "8", "hour", "3", "0", "minute", "reservation 7:00" can be changed to "reservation 8:30".

If no key is touched in this state, "white rice / brown rice / porridge" indicating the menu is displayed after 1 second and the position of the menu key is displayed. Here, when the position of "brown rice" is pressed and the rice cooking key 7b is pressed, a display as shown in FIG. 2c is displayed, and the current time, the reservation time and the menu "brown rice" are displayed.
