Description

[Detailed description of the invention] Industrial applications The present invention relates to a rice cooker for general household use. It is something.

BACKGROUND OF THE INVENTION 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, Further, 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 6 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. The present invention is intended to solve this problem, and aims to warn the user so that the user does not mistakenly execute the cancellation means.

3B-7 Means for Solving the Problems In order to solve the above problems, the present invention provides that when the user attempts to execute the cancellation means, a predetermined time period of one second or more is provided to indicate that the cancellation means will be executed. , a cancellation notification means is provided which can notify the cancellation.

According to this configuration, when the user attempts to execute the cancellation means, the notification is not given for a predetermined period of one second or more, and the user mistakenly executes the cancellation means and erases the display of the rice cooking operation. There will be no need to forget about the state of cooking the rice.

Embodiment Hereinafter, one 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 indicates a rice cooking means for performing a rice cooking operation, 12 indicates a control means for controlling the rice cooking means 11, and 13 indicates information on the rice cooking operation. This is a liquid crystal display means using an ordinary liquid crystal display element. 14 is 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 a timer means that performs a timer operation based on the output of the canceling means 16, and 17 a control means that outputs 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, in which 10 is a commercial power source, and rice cooking means 11 is a rice cooking heater 11a and a controller for the rice cooking heater 11a. It is composed of a relay contact 11b 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.

Page 6 / This liquid crystal display means 13 is composed of a rice cooking process display 13a, a tire hour display 13b, and a rice cooking menu display 13c. The rice cooking process display 13a displays corresponding characters in each of the pre-cooking, finishing, and additional cooking processes of the rice cooking operation using a liquid crystal display element, and the timer time display 13b indicates how many hours later the rice cooking will end. Furthermore, the rice cooking menu display 13c displays which menu the rice cooking operation is currently in progress.

One of the outputs of the canceling means 16 is a timer coil 16a.
The other output of the canceling means 16 is connected to the display driving means 14, so that the display on the liquid crystal display means 13 can be turned off. 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 canceling means 15, the timer coil 16a and the timer are activated by the output of the canceling means 15, so that the output of the canceling means 15 can be distinguished from the case where 6 degrees of cooking is notified for about 0.2 seconds to notify the start of rice cooking or the rice cooking state. contact 16b,
When the control means 17 operates, a buzzer constituting the cancellation notification means 18 emits an intermittent sound for a predetermined period of one second or more to notify the user that the cancellation means 15 will be executed and to call for attention. be.

Effects of the Invention As described above, according to the present invention, when the user attempts to execute the cancellation means, the user is notified for a predetermined period of one second or more, so that the user is prevented from accidentally executing the cancellation means. As a result, there is no longer a situation where the user accidentally erases the rice cooking status display on the rice cooker and loses track of what status it was in, as was the case in the past.
