Description

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

BACKGROUND ART A conventional rice cooker of this type had a configuration as shown in FIG. That is, the rice cooking operation is controlled by the control means 1, the rice cooking operation is performed by the rice cooking means 2 according to the output of the control means 1, and the rice cooking operation currently being performed by the rice cooking means 2 is displayed on the liquid crystal display means 3. Furthermore, the display drive means 4 outputs information on the rice cooking operation to the liquid crystal display means 3 based on the output of the control means 1. Reference numeral 5 denotes canceling means, which cancels the display on the liquid crystal display means 3 by outputting to the display driving means 4.

Problems to be Solved by the Invention In such a conventional configuration, if the user mistakenly executes the canceling means 5, the rice cooking operation display disappears, and as a result, it becomes unclear what kind of rice cooking state it was. There was a problem with this.

The present invention solves these problems,
To prevent users from accidentally executing the cancellation method,
The purpose is to alert users.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a method of notifying the user that the cancellation means will be executed for a predetermined period of one second or more when the user attempts to execute the cancellation means. This is provided with a means for notifying cancellation.

Effect: According to this configuration, when the user attempts to execute the canceling means, a notification is given for a predetermined period of one second or more, so if the user executes the canceling means by mistake, the rice cooking operation display disappears. There will be no need to worry about how hot the rice is cooked.

Embodiment Hereinafter, an embodiment of the present invention will be described based on the accompanying drawings.

FIG. 1 shows a block diagram of a rice cooker according to an embodiment of the present invention, in which reference numeral 11 denotes a rice cooking means for performing a rice cooking operation, 12 a control means for controlling the rice cooking means 11,
Reference numeral 13 denotes a liquid crystal display means using a liquid crystal display element for informing information on the rice cooking operation. 14 is a display driving means for driving the liquid crystal display means 13, and 15 is a canceling means, which provides an output to the display driving means 14 to erase the display on the liquid crystal display means 13. Reference numeral 16 denotes timer means for performing a timer operation based on the output of the canceling means 15, and reference numeral 17 denotes a control means for outputting an intermittent signal to the cancellation informing means 18 while the timer means is operating. The cancellation notification means 18 generates an intermittent sound in response to an intermittent signal from the control means 17 to notify that the cancellation means 15 is to be executed.

FIG. 2 shows a specific circuit diagram of a rice cooker according to an embodiment of the present invention, where 10 is a commercial power supply;
The rice cooking means 11 includes a rice cooking heater 11a, a relay contact 11b serving as a controller for the rice cooking heater 11a, and a relay coil 11c. The relay coil 11c is energized and controlled by the control means 12, and the relay contact 11b is controlled to open and close. As a result, current flows from the commercial power supply 10 to the rice cooking heater 1.
1a is energized and controlled to perform the rice cooking operation. on the other hand,
Information on the rice cooking operation from the control means 12 is displayed on the liquid crystal display means 13 by the display driving means 14.
This liquid crystal display means 13 includes a rice cooking process display 13a, a tire time display 13b, and a rice cooking menu display 13c.
It is composed of. The rice cooking process display 13a displays characters corresponding to each process of the pre-cooking process, the finished cooking process, and the additional cooking process using a liquid crystal display element, and also includes a timer time display 1.
3b displays how many hours later the rice cooking will end, and the rice cooking menu display 13c displays which menu the rice cooking operation is currently being performed.

One of the outputs of the canceling means 15 is connected to the timer coil 16a, and the other output of the canceling means 15 is connected to the display driving means 14, so that the display on the liquid crystal display means 13 can be turned off. ing. The timer contact 16b is input to a control means 17, and an output of the control means 17 is connected to a cancellation notification means 18 consisting of a buzzer.

When the user attempts to execute the cancellation means 15,
Cancellation means 15 is used so that it can be distinguished from the case where notification is made for about 0.2 seconds to notify the start of rice cooking or the rice cooking status.
The timer coil 16a, timer contact 16b, and control means 17 are operated by the output of 1.
For a predetermined period of time longer than seconds, a buzzer constituting the cancellation notifying means 18 emits an intermittent sound to notify the user that the cancellation means 15 will be executed and to call attention to it.

Effects of the Invention As described above, according to the present invention, when the user attempts to execute the canceling means, for a predetermined period of one second or more,
In order to notify the user, the user no longer accidentally executes the cancellation method, and as a result, unlike in the past, the rice cooker's rice cooking status display was erased by mistake, making it impossible to see what the status was. Things don't go away, they just go away.
