Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a microcomputer-controlled jar rice cooker used in general households.

BACKGROUND OF THE INVENTION Conventional microcomputer-controlled jar rice cookers are provided with separate rice-cooking switches for starting rice-cooking operations and heat-keeping switches for starting warming operations.

Problems to be Solved by the Invention However, the jar rice cooker with the conventional configuration described above has a large number of other switches, such as a switch for setting a one-hour timer for reservations, and a switch for stopping rice cooking and warming operations. This gives the user a feeling of clutter, tends to cause malfunctions, and is not easy to use.

The present invention solves the above-mentioned conventional problems, and aims to provide a jar rice cooker that is easy to use and can reduce parts costs.

Means for Solving the Problems In order to achieve the above object, the jar rice cooker of the present invention includes a rice cooking switch for starting rice cooking, and counts the number of times this rice cooking switch is operated. and rice-warming determination means for driving the rice cooking means to perform the rice cooking operation when the rice cooking switch is operated a predetermined number of times, and for driving the warming means to perform the rice cooking operation when the rice cooking switch is operated for a number of times greater than the predetermined number of times. The structure is as follows.

Effects According to the above configuration, the jar rice cooker causes the rice cooking operation to be performed when the rice cooking switch is operated a predetermined number of times, stops the rice cooking operation, and performs the warming operation when the rice cooking switch is operated more than the predetermined number of times. It is possible to perform two operations with one switch with simple operation, the number of switches is reduced compared to the conventional method, the user does not feel that the switches are complicated, and it is also cost effective. It is possible to do so.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to FIGS. 1 and 2.

In the figure, reference numeral 1 indicates a rice cooking/warmth determination means; when the rice cooking switch 2 is pressed once, a drive signal is output to the rice cooking means 3 to cause the rice cooking operation to be performed, and when the rice cooking switch 2 is pressed twice, the rice cooking means 3 is stopped. A signal is outputted to stop the rice cooking operation, and a drive signal is outputted to the warming means 4 to cause it to perform the warming operation. At this time, even if the rice cooking switch is pressed three or more times, it is ignored and the warming operation continues.

FIG. 2 shows a flowchart of the operation of the jar rice cooker according to one embodiment of the present invention.

First, wait for rice cooking switch 2 to be pressed (Step 1)
1). When the rice cooking switch 2 is pressed only once, a drive signal is applied from the rice cooking/warming determination means to the rice cooking means 3 to start the rice cooking operation (Step 12″b) Next, wait for the second operation of the rice cooking switch 2. (Step 13).If the rice cooking switch 2 is not pressed, wait for the completion of the rice cooking operation (Step 14), and when the rice cooking is completed, a stop signal is output from the rice warming determination means to the rice cooking means 3 to stop the rice cooking operation (
Step 16). Then, the process returns to the initial state (step 11) and the rice cooking switch 2 is pressed again. On the other hand, when the rice cooking switch 2 is operated for the second time in step 13, a stop signal is output from the rice keeping warm determination means 1 to the rice cooking means 3 to stop the rice cooking operation. A drive signal is output to the means 4 to start the heat retention operation (step 17). The warming operation continues unless the user terminates it (step 18), and the user applies a stop signal to the warming means 4 by operating the switch for stopping the rice cooking operation and the warming operation to stop the warming operation (step 19).
), the process returns to the initial state (step 11).

According to the above embodiment, it is possible to select the rice cooking operation and the warming operation with one rice cooking switch 2, and the number of switches can be reduced compared to the conventional switch group, so the user does not feel cluttered. This makes it easier to use without giving away too much. Furthermore, by reducing the number of switches, manufacturing costs can also be reduced.

In this embodiment, the rice cooking means 3 is driven when the rice cooking switch 2 is operated once, and the heat retention means 4 is driven when the rice cooking switch 2 is operated twice, but the number of times is not limited. Any device that drives the warming means 4 more often than the predetermined number of times for driving the rice cooking means 3 may be used.

Effects of the Invention As is clear from the description of the above embodiments, according to the present invention, two operations, cooking rice and keeping warm, can be selected with one rice cooking switch, and the user is not given the feeling of complication due to the large number of switches, making it easy to use. In addition, the number of switches can be reduced compared to the conventional one that has two switches, one for rice cooking operation and one for warming operation, and it is possible to provide a jar rice cooker that is advantageous in terms of cost. be.
