Description

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

Conventional configuration and its problems In a conventional rice cooker with a timer, if there is no pot while the timer is operating, when the rice cooking operation starts after the set time has elapsed, the heater is prevented from being energized without the pot. Therefore, the timer operation may be stopped or the timer set time may be cleared.9 With such conventional rice cookers with a timer, the user must grind the rice and place it in the pot before setting the timer. This has the disadvantage that changes to the amount of water and other changes while the timer is running must be done with the pot still in the rice cooker.

OBJECTS OF THE INVENTION The purpose of the present invention is to provide a timer-equipped rice cooker that can continue the timer operation even when there is no pot, in order to eliminate all the drawbacks of the conventional timer-equipped rice cookers and increase the convenience of use. It's about doing.

Structure of the Invention The rice cooker with a timer of the present invention includes a rice cooking means for performing a rice cooking operation, a timer means for performing a timer operation, a pot detection means for detecting the presence or absence of a pot, and a signal from the pot detection means is input, and the timer operation is performed by inputting a signal from the pot detection means. Inside, the timer operation continues regardless of whether there is a pot or not, and the rice cooking operation is stopped during rice cooking if there is no pot. It has been made possible.

DESCRIPTION OF THE EMBODIMENTS FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention. 1 is a timer means for performing a timer operation. 2 is a rice cooking means that performs a rice cooking operation.

3 is a pot detection means for detecting the presence or absence of a pot. Reference numeral 4 denotes a discriminating means, which does not discriminate the output of the pot detecting means 3 during timer operation and continues the timer operation regardless of the presence or absence of a pot, and during rice cooking operation, the output of the pot detecting means 3 determines if there is no pot. This is to stop the rice cooking operation.

FIG. 2 shows a specific configuration including the peripheral portion of this embodiment. Reference numeral 5 denotes a pot, around which a heater 6, a temperature sensor 7, and a pot detection switch 8 are provided. Reference numeral 9 represents a key switch for inputting the set time of the timer, 10 represents a reference clock serving as a reference for timekeeping operations, and 11 represents an indicator for displaying the operation of the timer and the like. Reference numeral 12 denotes a microcomputer, which implements the functions of the timer means, rice cooking means, and discrimination means shown in FIG. 1 by means of built-in programs.

Next, the operation of this embodiment will be explained with reference to FIG.

In step 2o, it is determined whether or not the timer is set by the key switch 9. If the timer is set, step 21 performs a clock cycle of the reference clock 10, and step 22 continues the timer operation until the timer operation ends. continue. When the timer operation ends, the rice cooking operation is performed using the heater 6 and the temperature sensor 7 in step 22. In step 24, the presence or absence of a pot is determined by the pot detection switch 8, and if there is no pot, the rice cooking operation is completely stopped.

In step 25, it is determined whether the rice cooking operation is finished.

Since the presence or absence of a pot is detected in step 24 only during the rice cooking operation, the timer operation continues even if there is no pot during the timer operation.

Therefore, until the rice cooking operation starts, even if the pot is removed, the timer operation will not be affected, and the user can freely change the amount of water, wash the rice, etc.

Effects of the Invention As is clear from the above embodiments, the rice cooker with a timer of the present invention has no relation to the operation of the timer and the presence or absence of a pot. It is possible to provide a rice cooker that can be prepared easily and eliminates operational constraints.

Claims (1)

[Claims] A rice cooking means that performs a rice cooking operation, a timer means that performs a timer operation, a pot detection means that detects the presence or absence of a pot, and a signal from this pot detection device is input, and while the timer is operating, the timer operation continues regardless of whether or not there is a pot. A rice cooker with a timer that serves as a determination means to stop the rice cooking operation if a pot is not present during the rice cooking operation.
