Process according to the. Specifically, when the lower casing 10 is attached to the water tank 30, normal heating control is performed, and when it is not attached, cooking is performed by reducing the heating power so as to reduce steam and spillage. For example, the control is changed to a control different from the normal heating control. The attachment / detachment detection means includes, for example, a touch sensor that detects that the lower housing 10 is attached to or detached from the water tank 30 by the operation of the lock mechanism 60 and outputs an on signal or an off signal.

  In the rice cooker configured as described above, first, the lower casing 10 in which water is put into the water tank 30 and then the heated object such as rice is put in the inner pot 11 is placed at a predetermined position on the water tank 30. Then, the lock mechanism 60 locks the position. And the operation part 23 of the lower housing | casing 10 is operated and the start of heat cooking is instruct | indicated. Thereby, the inner pot 11 is heated by the induction heating coil 12, and the water contained in the article to be heated in the inner pot 11 boils to generate steam.

  And while the amount of steam is small, the steam condenses in the upper lid side steam conduit 26 and returns to the inner pot 11, but when boiling increases and the amount of steam increases, the inner pot 11 has an atmospheric pressure. Than the pressure rises. Then, the steam generated in the inner pot 11 is pushed out by the pressure and from the upper lid side steam conduit 26 to the water tank side steam conduit 33 of the water tank 30 through the lower casing side steam conduit 15 in the lower casing 10. Inflow.

  And the vapor | steam which flowed in into the water tank side steam conduit 33 is ejected into water from the lower end opening of the water tank side steam conduit 33, is contacted with water, is cooled, and returns to water.

  By treating the steam in this way, the steam generated from the rice cooker 1 is prevented from leaking to the outside.

  Here, the water temperature in the water tank 30 gradually rises in the process of condensing steam, but the water tank 30 of this example has a size that allows the entire lower housing 10 to be placed. A sufficient amount of water can be stored. For this reason, it is possible to stably condense steam over a long period of time.

  Moreover, since the vapor | steam which flowed in in the water tank 30 returns to water in the water tank 30, the amount of water in the water tank 30 will gradually increase as cooking progresses, and a water level will become high gradually. Since the aquarium 30 of this example can store a sufficient amount of water as described above, the time until the aquarium becomes full can be extended compared to the case where a tank with a small amount of storage is used. Therefore, it is possible to stably condense steam over a long period of time. Moreover, it becomes possible to reduce the frequency | count of discard of water, and it is convenient.

  And when cooking is complete | finished, in order to carry a rice cooker main body (lower housing | casing 10 and the upper cover 20) to a table etc. as needed, the lock | rock by the lock mechanism 60 will be removed. Thereby, the lower housing | casing 10 and the water tank 30 are cut away, and it becomes possible to carry only a rice cooker main body (the lower housing | casing 10 and the upper cover 20). Therefore, compared with the rice cooker which incorporated the water tank 30 in the lower housing | casing 10, the lower housing | casing 10 is light and easy to carry. Further, if the induction heating coil 12 is provided on the water tank 30 side, the weight of the lower housing 10 can be further reduced.

  Further, the lower housing 10 and the water tank 30 are simply connected to a predetermined position on the water tank 30 without using a separate part such as a tube for connecting the lower housing 10 and the water tank 30. Since the steam passage portion with 30 is in communication, the lower housing 10 and the water tank 30 can be easily attached and detached.

  In addition, when the entire water tank 30 is formed of a transparent member, it is easy to grasp the current water level, and it is easy to check the state of contamination, and maintenance is facilitated.
