があつた。Problems to be Solved by the Invention With such conventional rice cookers, in cold regions, when rice and water that have been washed in the evening are placed in the pot and then cooked the next morning, the pot may become cold during the night. There were problems such as the water inside freezing and not being able to cook rice.
本発明は、このような従来の問題を解決した炊
飯器を提供することを目的としている。 An object of the present invention is to provide a rice cooker that solves these conventional problems.
問題点を解決するための手段
本発明は上記問題点を解決するため、炊飯開始

する構成となつている。Means for Solving the Problems In order to solve the above-mentioned problems, the present invention has a structure that duty-controls the electricity supply to the heating means when the temperature of the pot falls below a predetermined temperature during the period until the start of rice cooking. It's summery.
作 用
この構成により、鍋の温度が氷点近くまで低下
すると、加熱手段により鍋が加熱されるため、外
気温が氷点以下となつても鍋は氷点以上に保たれ
鍋の中の水が凍ることがなく、どのような寒冷地
でも安心して夕方に翌朝の炊飯の準備ができる。Effect With this configuration, when the temperature of the pot drops to near the freezing point, the pot is heated by the heating means, so even if the outside temperature falls below the freezing point, the pot is kept above the freezing point and the water in the pot does not freeze. No need to worry about cooking rice in the evening, no matter how cold the region is, you can prepare rice for the next morning.

FIG. 1 is a block diagram showing one embodiment of the rice cooker of the present invention. 1 is a rice cooking means for performing a rice cooking operation, and a rice cooking heater (heating means) 1-a
and a power control element 1-b. 2 is a pot, and 3 is a temperature detection means for detecting the temperature of the pot 2, which is composed of a temperature sensor 3-a and a temperature detection circuit 3-b. Reference numeral 4 denotes a control means which receives the output of the temperature detection means 3 as an input and controls the rice cooking means 1 during the period until the start of rice cooking.

がない。 Let's explain the operation. The user puts washed rice and water into pot 2. The temperature detection circuit 3-b detects whether the temperature of the temperature sensor 3-a is near the freezing point (here, 5°C), and if the temperature falls below 5°C, it outputs a signal to the control means 4, and the control means 4 Using that signal as input, relay 1-b is closed and rice cooking heater 1-
a is connected to a commercial power source 5 for heating. In addition, since it takes time for the heat of the rice-cooking heater 1-a to be transmitted to the pot 2 and further to the temperature sensor 3-a, the rice-cooking heater 1-a was continuously heated until the temperature sensor 3-a reached 5°C. , the temperature sensor 3-a is 5
There is a possibility that the temperature of rice cooking heater 1-a has risen too much when the temperature reaches ℃.
a needs to be duty-controlled. Here, control means 4 turns on the relay for 1 second, and then turns it on for 15 seconds.
Opening/closing is controlled by the OFF duty. As a result, the temperature rise of the rice cooking heater 1-a is suppressed, and the temperature difference between the temperature sensor 3-a and the rice cooking heater 1-a is suppressed. With this configuration, the temperature of the pot 2 is controlled to 5° C. or higher even in cold regions, and the water in the pot 2 does not freeze.
発明の効果
以上述べてきたように、本発明によれば寒冷地
においても夕方洗米した米と水を鍋に入れて本体
にセツトして翌朝炊飯を行なう場合、夜中の冷え
込みのために鍋の中の水が凍つてご飯が炊けない
という従来の問題が解消でき、実用的にきわめて
有用なものとなる。Effects of the Invention As described above, according to the present invention, even in cold regions, when rice and water that have been washed in the evening are placed in a pot and set in the main unit to cook rice the next morning, the rice and water that have been washed in the evening can be placed in the pot to prevent the rice from getting cold during the night. This solves the conventional problem of not being able to cook rice because the water freezes, making it extremely useful for practical purposes.
