Description

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

Prior Art In conventional rice cookers of this type, the desired rice cooking start time was generally set within 12 hours from the current time. That is, the current time is subtracted from the desired time to start cooking rice, and that time is set by a timer means.

Problems to be Solved by the Invention In such a conventional configuration, the user had to subtract the current time from the rice cooking start time, which was complicated and inconvenient to use. On the other hand, timer means for setting scheduled times, such as those found in audio equipment, are easy to use because the desired start time can be set, eliminating the need for time calculations. The timer device can be set for more than 12 hours, so if the user sets it for a long time (for example, 15 hours) and the water temperature and room temperature are high, the rice will rot and the rice will not be cooked properly. Furthermore, even if it was noticed that the setting had been set for a long time, the rice that had been poured into the pot with water could not be returned to its original dry state, causing problems such as difficulty in disposing of the rice.

An object of the present invention is to provide a rice cooker that solves these conventional problems.

Means for Solving the Problems In order to solve the above problems, the present invention has a built-in clock means that allows the user to reserve the start or end time of rice cooking, and also detects the temperature of water and rice in the pot. Therefore, even if the desired rice cooking start or end time is set after a long time, rice cooking will start at a time corresponding to the temperature (for example, 12 hours at 30℃, 20 hours at 5℃). .

Function The above clock means allows you to reserve the time to start or end rice cooking, making it more convenient to use, and even if the user sets a timer for a long time, the timer waits until the limit at which the rice does not spoil, depending on the water temperature. Since the rice starts cooking after the rice is freshly cooked, the rice does not spoil and can be eaten in a state as close to freshly cooked as possible.

Embodiment Hereinafter, an embodiment of the present invention will be described based on the accompanying drawings. FIG. 1 shows the operation section of a rice cooker according to an embodiment of the present invention. Reference numeral 1 denotes a reservation time input means, and this reservation time input means 1 includes a set switch 2 for setting the reservation time, and a "set switch 2" for setting the reservation time. It has an hour switch 3 for setting the hour and a minute switch 4 for setting the minute of the reservation time.
Reference numeral 5 denotes a reservation time display means for displaying the desired rice cooking start time inputted by the reservation time input means 1.
6 is a start switch for inputting the start of rice cooking or the start of timer operation.

In the above configuration, if you want to operate the timer, press the set switch 2, then use the hour switch 3 and minute switch 4 to set the desired time at which you want to start the rice cooking operation. Then, when the start switch 6 is pressed, the timer means starts.

Fig. 2 shows a block diagram of the rice cooker, and 7 is a storage means for storing the desired rice cooking start time inputted by the reservation time input means 1, that is, the reservation time, and the output of the storage means stores the reservation time. The time is displayed on the reserved time display means 5. Reference numeral 8 denotes a clock means that constantly clocks the current time and outputs it to the comparison calculation means 9. 10 is a temperature detection means that detects the temperature of water and rice in the pot. 11 is a timer means that measures the time corresponding to the temperature detected by the temperature detection means 10 (for example, 20 hours at 5°C, 15 hours at 30°C) from the time when the start switch 6 is pressed, and measures the elapsed time. Then, it is output to the comparison calculation means 9. The comparison calculation means 9 calculates the reservation time from the storage means 7 and the current time from the clock means 8.
After inputting the output from the timer means 11 and pressing the start switch 6, if the above-mentioned reserved time and the current time match within the time corresponding to the temperature detected by the temperature detecting means 10, the rice cooking means 12 starts at that point.
The rice cooking operation is started by controlling the

Effects of the Invention As described above, according to the present invention, since the rice cooking start or end time setting type is set with a built-in clock means, compared to the conventional time setting type, the rice cooking start time based on the current time is There is no need to do complicated calculations to calculate the time, which improves usability.Also, even if the desired rice cooking start time is set to a time that exceeds the permissible soaking time for rice, water and rice The rice cooker starts cooking at the limit of the soaking time at which the rice will not spoil, depending on the temperature of the rice, thereby eliminating the mistakes of spoiling the rice and not being able to cook delicious rice.

Claims (1)

[Claims] 1. A rice cooking means for performing a rice cooking operation, a reserved time input means for inputting the start or end time of rice cooking, and a storage means for storing the reserved time;
A reserved time display means for displaying the reserved time, a clock means for measuring the current time, a temperature detecting means for detecting the temperature of the pot, a timer means for inputting the temperature detected by the temperature detecting means, and a timer means for inputting the temperature detected by the temperature detecting means. It is equipped with a start switch for starting a time measurement operation, and a comparison calculation means for inputting signals from the storage means clock means and timer means, and when the timer means receives the signal from the start switch, it calculates the measurement time based on the temperature of the temperature detection means. Along with setting,
A rice cooker in which a timing operation is started, and the comparison calculation means starts the rice cooking operation at the earlier of the time when the timer means issues a measurement time end signal or the time when the contents of the storage means and the clock means match. .
