Embodiment approach 1

[0083] figure 1 A cross-sectional view of the rice cooker according to Embodiment 1 of the present invention is shown. figure 2 An enlarged cross-sectional view of the steam superheating portion of Embodiment 1 and the flow of steam are shown.

[0084] The rice cooker according to Embodiment 1 cooks rice under atmospheric pressure. exist figure 1 Among them, reference numeral 1 represents the main body of the rice cooker, and a pot 2 that can be assembled and disassembled is housed in it. The main body 1 is provided with a cover 3 in a freely openable and closable manner, and the cover 3 covers the upper surface of the main body 1 .

[0085] The main body 1 has: a pot heating unit 4 (an example of the first heating unit, such as an induction heating coil), which inductively heats the pot 2; a pot temperature detection unit 5, which detects the temperature of the pot 2; a steam generating unit 6 , which is used to generate steam; and a control unit 7 .

Abstract

The invention provides a cooking device. For the prior art, steams of atmospheric pressure are guided in a cooking device, but steams cannot cover all rice and half-cooked rice will be produced. In order to further enhance rice cooking, a water groove and a water groove heating unit are separated from a boiler. Steams generated in the water groove are heated to temperature over 100 DEG by means of a heating plate and are guided in to the boiler. In such a cooking device, steam temperature tends to be stabilized and rice surface will be dry when the temperature of heating rice is excessively raised. In a process of braising and steaming, temperature of steams generated by a steam generating unit can be raised and the steams can be guided into the boiler, and the pressure in the boiler is no less than the atmospheric pressure. Accordingly, all rice can be maintained above the temperature of 100 DEG to enhance cooking, and rice of a whole boiler can be well cooked. Even if steam guiding amount is less than ever before, all rice can be maintained above the temperature of 100 DEG in the braising and steaming process, enhancing rice cooking.

Description

technical field [0001] The present invention relates to a rice cooker using superheated steam, in particular to a rice cooker with improved rice cooking performance. Background technique [0002] Conventionally, in general household rice cookers, a pot heating unit arranged at the bottom of the pot for heating rice and water in the pot is the main heating unit. In order to cook rice well, it is important to fully gelatinize the starch of the rice. In particular, high temperature is used to heat rice during stewing and steaming to promote the gelatinization of starch and increase the sweetness and fragrance of rice. However, since the water almost disappears during steaming, if the pot heating unit continues to reheat, the rice near the bottom of the pot will be burnt, so the heating has to be reduced. [0003] For example, if Figure 8 As shown, there is a rice cooker that heats rice and water by spraying high-temperature steam into the pot from above the pot in addition t...
