Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a rice cooker for use in general households.

2. Description of the Related Art In conventional rice cookers of this type, the current time is subtracted from the desired time to eat rice, and that time is set by a timer means. Then, when the user presses the start switch, the timer means starts measuring time, outputs an output about one hour before the user wants to eat rice, and rice cooking starts.
At the time when you want to eat rice, the rice cooking is finished and the user
I wanted to be able to eat delicious, freshly cooked rice.

Problems that the invention seeks to solve With such a conventional configuration, is it inevitable that rice will not be cooked? If the start time is fixed and you try to use a timer to cook rice with different cooking times such as white rice, brown rice, porridge, takikomi, and rice, you will need multiple timers, and as a result, the configuration will be different. There were problems such as complexity, significantly higher cost, and lower reliability.

The entire purpose of the present invention is to provide a rice cooker that solves these conventional problems.

Means to Solve All Problems In order to solve the above problems, the present invention provides a rice cooking means for performing the rice cooking operation, a knob for the user to set the timer time, and a digital value for the rotation angle of this knob. A to convert
/ D conversion means, a start switch for starting timer time measurement, a time measurement means for starting time measurement with this start switch, and a time measured by this time measurement means and an output from the A/D conversion means. A rice cooking operation is performed by controlling the rice cooking means and a time display means that calculates the difference between the timer setting times and displays this time, and compares the output of the time measurement means and the output of the M/D conversion means. and a control means for starting the process.

Function According to the above configuration, the user can subtract the current time from the time he or she wants to eat the meal, and set the time by fully rotating the knob without looking at the display on the time display means. Rice cooking starts at a time determined by the menu of the dish before the desired time, and ends by the time the rice is ready to be eaten.

Embodiment Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings. Fig. 1 shows the operation section of a rice cooker in one implementation of the present invention, where 1 is a knob for setting the timer for one hour;
is the start switch to start timer rice cooking, 3
is a time display means for displaying the remaining time of one hour of the timer.

In the above configuration, when performing timer rice cooking, rotate the knob 1 until the value obtained by subtracting the current time from the time you want to eat the rice is displayed on the time display means 3, and then press the start switch 2. The rice will finish cooking at the time you want to eat it.

FIG. 2 shows a block diagram of a rice cooker according to an embodiment of the present invention. Reference numeral 4 indicates a rice cooking means for performing the rice cooking operation, 1 indicates a knob for the user to set the timer time, and 6 indicates a knob for setting the timer time. Mu/D conversion means for converting the rotation angle into a digital value; 2 is a start switch for starting timer time measurement; 6
3 is a time measuring means that starts time measurement by the start switch 2, and 3 is the time measured by this time measuring means 6.
I11 Time display means that calculates the difference between the timer setting times output by the conversion means 6 and displays this time; 7 is the rice cooking means 1;
This control means starts the rice cooking operation by controlling the output of the time measuring means 5 and the output of the A/D converting means 5.

The operation in the above configuration will be explained. The user sets the desired eating time by subtracting the current time by rotating the knob 1, and the value is determined by the A/D conversion means 5.
It is digitized and displays the time value. Therefore, since no time is being measured before the start switch 2 is pressed, the one-hour timer setting value of the knob 1 is displayed.

When the user presses the start switch 2f, the time measuring means 6 starts measuring time, and this measured time is constantly output. The time display means 3 subtracts this output measurement time from the timer setting time output by the M/D conversion means 5 and displays the remaining time.

The control means 4 compares the measurement time output by the time measurement means 6 and the timer setting time output from the M/D conversion means 6,
When the time lag varies depending on the menu of the dish, the operation of the rice cooking means 4 is started, and when the desired time comes, the rice cooking is finished.

Effects of the Invention As described above, according to the present invention, in timer cooking where the rice is ready at the desired time, the timer time can be set by rotating the knob while looking at the display on the time display means. In addition, since the rice cooking start time can be arbitrarily determined, rice such as brown rice other than white rice can be cooked at the desired time by setting a timer.
