Reserve.

Next, the operation of the rice cooker 1 according to the embodiment of the present invention will be described with reference to the accompanying drawings.

First, explain the situation of cooking rice.

At the time of cooking, as shown in Fig. 2, the washed rice and water are placed in the inner pot 3, and the lid body 10 is simmered and boiled. As shown in FIG. 5, the vapor generated in the inner pot 3 enters the vapor flow path 56 between the dew condensation retainer 7 and the inner lid 5 from the vapor passage hole 71d and the dew condensation recovery hole 71e.

When the internal pressure in the vapor flow path 56 rises above a predetermined pressure, the pressure regulating valve 63 is opened by the vapor pressure. As a result, the vapor in the vapor flow path 56 flows into the roof surface 62e in the pressure regulating valve arrangement space 62g through the pressure regulating valve 63. When the pressure regulating valve arrangement space 62g is filled with steam, it passes over the partition 62n and flows into the roof surface 62e in the vapor storage space 62h. When the vapor storage space 62h is filled with steam, the vapor passes over the partition 62o, enters the roof surface 62e in the discharge port arrangement space 62i, and is discharged to the outside from the discharge port 62d.

In this way, the steam flows in the steam flow passages 56 and 64 so as to meander in the right and left directions, and is temporarily trapped in the pressure regulating valve arrangement space 62g, the steam storage space 62h, and the discharge port arrangement space 62i. Stay, so it is difficult to discharge to the outside.

Moreover, when the lid body 10 is opened, as shown in FIG. The condensation adhering to the lower surface of the condensation receiving tray 7 falls and enters the front vapor flow path 56 from the condensation recovery hole 71e. As shown in Fig. 5, the condensation entering the vapor flow path 56 is stored on the dish portion 71a of the dew condensation tray 7. Further, the condensation in the vapor flow path 64 is temporarily stored in the lower casing 61 and then flows out from the condensation discharge port 61g to the inner cover 5.

Then, the condensation in the vapor flow path 56 and the inner lid 5 is heated by the lid heater 48 to be vaporized, and the vapor flows back into the inner pot 3 by the vapor flow path 56 to be steamed. .

In the rice cooker 1 of the present invention, the steam generated during cooking is suppressed from being discharged to the outside of the rice cooker 1, and the steam can be trapped in the rice cooker 1 in an appropriate state. Further, in the rice cooker 1, the condensation which falls when the lid body 10 is released flows back into the lid body 10, and the inflowing dew condensation is again turned into steam by the lid heater 48, and is returned to the inner pot 3. The vapor pressure in the inner pot 3 is maintained in a good state. Therefore, it is possible to suppress the rice from becoming dry.
