Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a rice cooker that displays an uneven time display and a reheating display.

[Conventional technology]

Conventional rice cookers of this type display the uneven time display on the numeric display, and the re-cooking display is displayed using a separate re-cooking lamp, etc., but with this,
The drawbacks were that it was difficult to see, had a large number of parts, and was expensive.

[Summary of the invention]

This invention was made to improve this problem, and by displaying the uneven time display and the reheating display on the same display, the display is easy to see and can be manufactured at low cost. We are proposing a rice cooker.

[Embodiments of the invention]

Hereinafter, one embodiment of the present invention will be described based on the drawings.

FIG. 1 shows an overall configuration diagram of a rice cooker according to an embodiment of the present invention.

As is clear from FIG. 1, a heating element 2 is provided to heat the rice cooker 1 from the bottom thereof, and a display 3 is provided to display the rice cooking time and additional cooking time, and when the rice cooking process is completed, the rice cooking process starts. Means 4
The unevenness process is started, and the unevenness time is displayed on the display 3 by the unevenness time display means 5.

In this embodiment, the irregularity time is set to 15 minutes, and 15 minutes is displayed at first, and thereafter, a countdown is displayed.

Next, when 8 minutes have passed from the start of the unevenness process, the additional cooking process is started by the additional cooking process start means 6, the additional cooking heating means 7 controls the heating element 2, and the additional cooking display means 8 displays the information on the display 3. The device is configured to display that the additional cooking process is in progress.

FIG. 2 is a circuit diagram showing the electrical connections of the embodiment of FIG. 1.

In the figure, 9 indicates input circuit 10, memory 11, CPU
12 and an output circuit 13.

A circuit for lighting the display 3 is connected to output terminals 14, 15, and 16 of the output circuit 13. The display 3a displays the 10th digit, and the display 3b displays the 1st digit using a dynamic display method.

The output terminal 14 is connected to a segment terminal of the display 3 via a resistor 18. The output terminal 14 and the resistor 18 are composed of seven pieces and are connected to seven segment terminals.

The output terminal 15 is connected to the digital terminal of the display 3a via a resistor 19 and a transistor 20, and the output terminal 16 is connected to the digital terminal of the display 3b via a resistor 21 and a transistor 22. Thereby, the uneven time and additional cooking display are displayed on the same display 3.

In addition, a resistor 2 is connected to the output terminal 17 of the output circuit 13.
A transistor 24 is connected through the transistor 3, and a relay coil 25 is connected to the transistor 24. The heating body 2 is controlled by opening and closing a relay contact 26 of the relay coil 25. The Vss terminal 27 is a power source for the microcomputer 9 and the relay coil 25, and 28 is a commercial frequency power source.

Next, the operation of the above embodiment will be explained with reference to FIGS. 3 and 4.

Figure 3 shows the memory 11 of the microcomputer 9.
FIG. 4 is a flowchart showing the unevenness/additional cooking process stored in , and FIG. 4 is a diagram showing the unevenness time display and additional cooking display.

When the rice cooking process is finished in step 29, step
The unevenness process starts at 30, and the unevenness time of 15 minutes is displayed on the display 3 as shown in FIG.

When 8 minutes have elapsed after the start of steaming in step 31, the process advances to step 32 and the additional cooking process starts.
At this time, as shown in FIG. 4B, during the additional cooking, four segments in the upper half of the display 3a are displayed in a donut shape. In other words, the display 3 in Figure 4B
The right half shows that the remaining cooking time is 7 minutes, and the left half shows that additional cooking is in progress.

Further, a control section including an output circuit 17, a resistor 23, a transistor 24, and a relay coil 25 closes a relay contact 26, and the heating element 2 heats the pot 1 to perform reheating.

Next, in step 33, the cooking time is T seconds (for example, 40
seconds), the process advances to step 34, where the additional cooking process is completed and the additional cooking display is stopped.

When the uneven time of 15 minutes has elapsed in step 35, the process proceeds to step 36, where the uneven process is completed and the uneven time display is stopped.

In this way, the irregularity display and the overcooking display are displayed on the same display 3, which makes it easy to see, reduces the number of parts, and can be manufactured at low cost.

〔Effect of the invention〕

As described above, according to the rice cooker of the present invention, since the uneven time display and the additional cooking display are displayed on the same display, the display is easy to see and can be manufactured at low cost.
