Description

  The present invention relates to a rice cooker that can set a rice brand to be cooked and cook rice in a rice cooking sequence that matches the set brand.

  In general, as shown in FIG. 11, this type of rice cooker has a water absorption process for sucking water into rice while keeping the water temperature at a temperature slightly lower than the gelatinization start temperature of rice starch, and a cooking process for boiling the inside of the pan. In addition, a power-down process that suppresses boiling in the pan for a certain period of time to prevent spilling, a boiling maintenance process that maintains boiling until the water in the pan runs out and the rice is made into a water-absorbing gelatin, and the surface of the rice grain The rice is cooked according to a rice cooking sequence consisting of a steaming step that absorbs the free water remaining in the rice grains and promotes gelatinization.

  However, because there are various brands of rice, and the characteristics differ depending on the brand, it is not possible to extract the maximum deliciousness of the rice by cooking rice with different brands using the same cooking sequence. It was possible. In other words, for example, if you cook rice with a very soft texture, such as Koshihikari from Uonuma, the grain structure collapses during cooking, and the rice becomes sticky and has a poor texture. When rice having a hard nature such as a cultivated rice is cooked, there is a problem that the core of the grain becomes hard and non-sticky rice, and a preferable taste cannot be obtained.

  The reason for this is that in the water absorption process, the rice and water are kept at a high temperature slightly lower than the temperature at which starch gelatinization starts in order to promote water absorption and promote saccharifying enzyme action in the water absorption. Although the time is maintained, as is widely known, the rate of water absorption of rice (which indicates how much water the rice absorbs over time) varies depending on the brand of rice, so the water absorption is fast The rice with the soft nature of the tissue becomes excessively water-absorbed and the starch gradually dissolves, resulting in the collapse of the grains and stickiness in the subsequent rice cooking process, while the rice with the slow nature of water absorption and the hard nature of the tissue is sufficient to the center of the grain This is because the process proceeds to the cooking process without being able to absorb water and the starch is not easily converted to alpha (alpha) in the subsequent cooking process.

Therefore, with conventional rice cookers, it is possible to set the brand of rice to be cooked before cooking rice, and by cooking with a rice cooking sequence that matches the nature of the set brand, maximize the original taste of rice (See, for example, Patent Document 1).
JP 2002-300963 A

  However, the above conventional rice cooker aims to maximize the original taste of a single brand of rice, and blended rice (a combination of different brands depending on the dish and taste) is considered. If, for example, blended rice blended with soft rice typified by Uonuma Koshihikari and hard rice typified by Hokkaido rice is cooked in a rice cooking sequence that matches soft rice, In the state where water absorption to hard rice is insufficient, it proceeds to the cooking process, and even after the rice cooking process, starch alpha conversion does not progress easily, and as a result, the core of the grain becomes hard and non-sticky rice, on the contrary When rice is cooked with a rice cooking sequence that matches the hard rice, the water absorption to the soft rice in the water absorption process becomes excessive, resulting in the grain structure collapsed and a poor texture. There is a problem that becomes rice.

  The present invention solves the above-described conventional problems, and allows a plurality of brands included in the blended rice to be cooked before cooking rice to be cooked in a rice cooking sequence suitable for a combination of a plurality of set brands. It aims at providing the rice cooker which can cook the blended rice which combined several brands with a better taste by doing.

  In order to achieve the above-mentioned object, the present invention heats a pot in which rice and water are stored inside a rice cooker body by heating means, detects the temperature of the pot by pot temperature detecting means, and heats the heating means by heating control means. The combination of a plurality of rice brands included in the blended rice is set by the blended rice setting means, and stored in the storage means by the rice cooking sequence determination means based on the combination of the plurality of rice brands set by the blended rice setting means. The cooking control sequence is configured to determine the cooking sequence to be used from among the cooking sequences being cooked, and the cooking control sequence is determined by the cooking sequence determination unit based on a combination of a plurality of rice brands set by the blended rice setting unit. It is possible to cook rice by controlling the heating means based on the temperature detected by the pot temperature detecting means and the time measured by the time measuring means. One in which the.

  As a result, even when blended rice that is a combination of multiple brands is cooked, just by setting a combination of multiple brands included in the blended rice before cooking, it is suitable for a combination of multiple brands that have been set. Rice can be cooked in the rice cooking sequence, and blended rice combining a plurality of brands can be cooked with a better taste.
