った。2. Description of the Related Art Conventionally, as a domestic rice cooker, a rice cooker is accommodated in a rice cooker main body, and an upper opening thereof is closed with a lid rotatably provided in the rice cooker main body. 2. Description of the Related Art There is known a type in which rice is cooked by heating a rice cooker with a heating means (such as an induction heating coil or a resistance wire heater) provided in the body. Further, in order to discharge steam generated during rice cooking to the outside of the cooker, a steam passage communicating between the inside of the rice cooker and the outside of the cooker is provided in the inside of the cover, and a steam hole is provided in an upper part of the cover. Normal. In a rice cooker with such a configuration,
Since steam generated during rice cooking is released from the steam hole to the outside of the device, there is a problem that the steam is condensed around the rice cooker.

For example, a heater in which the inside of the lid is hollow, an exhaust port and a water vapor inlet are formed on the top plate and the bottom plate of the lid, and an adsorbent storage chamber containing an adsorbent so as to cover the water vapor inlet is provided. This is known (see Japanese Patent Application Laid-Open No. 5-168559). There is also known a rice cooker in which a gap is provided between an inner lid provided on a lid and a radiator plate so that steam generated in a rice cooker is condensed in the gap (Japanese Patent Laid-Open No. 2000-1).
No. 75810).

るという問題がある。However, in the heater described in JP-A-5-168559, although a large amount of adsorbent is present in the lid, only a part of the adsorbent contributes to vapor adsorption. And the adsorption efficiency is low. In addition, Japanese Unexamined Patent Application Publication No. 2000-17581
In the rice cooker described in Japanese Patent Publication No. 0, it is necessary to wipe off condensed steam every time rice cooking is completed, and there is a problem that the structure becomes complicated.

く接触し水となって効率よく吸着させることができる。[0007] In the rice cooker, steam generated from the rice cooker housed in the main body passes through a steam passage from a steam inlet and is discharged outside from the steam outlet. At this time, the steam diffuses throughout the steam passage due to the capillary phenomenon and the exhaust pressure of the steam because the gap in the steam passage is as narrow as 1.0 mm or less. Therefore, the steam can evenly contact the adsorbent disposed around the steam passage and become water to be efficiently adsorbed.

If the heating means is operated with small electric power during the heat retention process, the rice cooked in the upper part of the rice cooker will be kept warm and the water adsorbed by the adsorbent will be turned into steam to be gradually released to the outside of the cooker. Is preferable because it can be automatically recovered.

2 is disposed inside the lid 2 so that steam generated during cooking rice can be discharged outside the device. Steam passage 12
(FIG. 1 (a)) is set to 1.0 mm or less so that the generated steam is diffused evenly in the steam passage. An adsorbent 13 such as silica gel or zeolite is provided around the vapor passage 12 so that the vapor passing through the vapor passage 12 comes into contact with the adsorbent 13 and condenses to be adsorbed as water. . Further, a lid heater 16 is disposed below the lid 2, specifically, near the lower part of the adsorbent 13.

飯器周囲に悪影響を与えることを極力防止できる。After the rice cooker 5 is set in the main body 3, the lid 2 is closed and the display operation unit 15 is operated to perform a desired rice cooking operation. This rice cooking operation is a well-known operation performed by a conventional rice cooker, and thus details are omitted. During cooking, particularly during the so-called boiling maintaining step or the double cooking step, steam is actively generated from the rice cooker 5, and the generated steam is discharged out of the vessel through the steam inlet 10, the steam passage 12, and the steam outlet 11. On the way, the vapor contacts the adsorbent 13 in the vapor passage 12 and condenses. Therefore, the amount of steam discharged outside the vessel can be significantly reduced. Further, since the gap of the steam passage 12 is as small as 1.0 mm or less, the steam is uniformly diffused into the steam passage 12 due to the capillary action and the exhaust pressure of the steam, and efficiently contacts and condenses with the adsorbent 13. Therefore, the amount of steam discharged outside the vessel decreases. After the rice cooking is completed, the process automatically shifts to the heat retaining step. In the heat retaining step, the lid heater 16 is operated with small electric power (about 40 W). Therefore, the temperature of the cooked rice in the upper portion of the rice cooker 5 is maintained at an appropriate temperature (approximately 72 ° C.), and the adsorbent 13 is also heated by the lid heater 16, and the water adsorbed on the adsorbent 13 evaporates gradually and the vapor passage Through the steam outlet 11
Is released out of the vessel. Therefore, the adsorbing performance of the adsorbent 13 is automatically restored, and the amount of steam generated per unit time at this time is smaller than that during the cooking of rice, so that it is possible to minimize the adverse effect on the periphery of the rice cooker.
