(Problems to be Solved by the Invention) In the above-described conventional technique, in Patent Document 1, a water tank is provided in a main body or an outer cover, and a water storage portion is provided at the bottom of the inner pot, and, -6-200948319 In the literatures 2 and 3, the water tank is detachably attached to the lower surface of the inner cover which covers the upper opening of the inner pot. Therefore, it is necessary to put water into the sink before cooking, and the ease of use is not If it is forgotten to put water into the sink or the like before cooking, and there is no water, the steam cannot be supplied to the inner pot during the heat preservation to reduce the drying of the rice. Further, in Patent Documents 4 and 5, the dew receiving tray attached to the inner portion of the inner lid side of the inner lid is extremely smaller than the entire inner lid, and the entire lower jaw surface of the inner lid is exposed inside the inner pot. Moreover, since the gap is formed between the entire circumference of the outer peripheral surface of the dew receiving tray and the lower surface of the inner pot, the inner lid and the dew receiving tray are heated from the high temperature steam generated in the inner pot to the same temperature during cooking. Condensation will occur, and the high-temperature vapor will be discharged from the vapor vent opening opened at the center side of the inner pot toward the outside of the body. As a result, the dew condensation water does not remain in the condensation receiving tray, and it is impossible to supply the vapor into the inner pot during the heat preservation, and the drying of the rice cannot be lowered. Θ (Means for Solving the Problems) The present invention is to solve the above-mentioned problems, and the first aspect of the patent application is an electric cooker having a main body and a cover covering the upper opening of the main body. And an inner pot detachably housed in the body, an inner cover covering the upper opening of the inner pot, an inner cover vapor passage provided in the inner cover, and an outer cover provided outside the outer cover a cover vapor passage and a restriction means for restricting passage of steam between the outer cover vapor passage and the inner cover vapor passage, wherein the outer cover includes a lid heating means for heating the inner lid, wherein the inner lid is The underside of the inner cover is provided with a nearly 200948319 fully covered condensation receiving tray, which is composed of a material having a smaller heat capacity than the inner cover, and whose outer peripheral surface is in close contact with the lower surface of the inner cover, and A vapor flow path having an opening area larger than the inner cover vapor passage is provided at a position facing the inner cover vapor passage. In the second item of the patent application, in the cooking, the inner lid is not heated by the lid heating means, and the restricting means does not restrict the passage of the vapor from the inner lid vapor passage toward the outer lid vapor passage, and cooking In the heat preservation operation after the migration to the boring, the passage of the steam is restricted by the restriction means, and the inner lid and the condensation receiving tray are heated by the lid heating means. In the third application form, the condensation receiving tray has a bulging portion that protrudes toward the inner lid side, and the vapor flow path is provided on the upper surface of the bulging portion. [Effects of the Invention] According to the present invention, since the vapor generated during cooking is dew condensation on the inner lid, the dew condensation water is retained as a water droplet in the dew receiving tray, and the water is changed into steam for use in boring and heat preservation. Therefore, it is not necessary to discharge water to the condensation receiving tray before cooking, and steam can be used to realize an electric cooker that can be cooked and kept warm. Moreover, since the vapor generated by the condensation receiving tray is not released from the outer cover vapor passage to the outside by the restriction means, it can be guided into the inner pot, and the inner pot can be filled with steam, whereby The rice in the inner pot is fully suffocated, and the rice is deliciously prepared. Further, in the heat preservation, the temperature is also lower than that of the boring rice. Similarly, the vapor generated by the lid heating means is not released to the outside air by the restriction means of -8 - 200948319, and the inner pot can be humidified by the steam. Keep warm while suppressing the drying of rice. Moreover, even if the cover is opened for the purpose of filling the rice, the dew condensation water remaining on the condensation receiving tray does not drip from the vapor flow path toward the inner pot, and the body is not wetted, and the outer cover can be closed again if the outer cover is closed again. The inside of the pot is humidified by steam, which can be effectively used to suppress the drying of the rice.

At this time, the gap 6 including the inner lid 4 and the condensation receiving tray 5 is also included in this space. -11 - 200948319 Thereafter, when the user performs the rice cooking operation, the cooking starts, and the heating device 12 is energized to turn off the hot air. However, at this time, the lid heating means 〇 is not energized. After the inner dragon (four) of the inner pot 3, hot water 低 (low-flowing steam) occurs, and condensation forms on the inner side of the inner pot 3 of the dew receiving tray 5. Further, the condensation receiving tray 5 is heated by the latent heat of the vapor, and the temperature of the condensation receiving tray 5 is raised to a temperature state close to the hot water inside the inner pot 3. At this time, the inner cover 4 is almost completely covered by the condensation receiving tray 5, and the water-gas (low-temperature steam) is exposed to the radiant heat from the condensation receiving tray 5 because it is not in contact. Condensation takes over the lower temperature of the tray 5 (rise). When the inside of the inner pot 3 is boiled, the pressure is increased by the vapor, and the vapor flows into the gap 6 formed by the inner lid 4 and the dew receiving tray 5 from the vapor flow path 5d of the dew receiving tray 5. Further, as shown in Fig. 2, the restriction means 9 is opened, and is discharged to the outside through the inner lid vapor passage 7, the restriction means 9, and the outer cover vapor 0 passage 8, because the condensation receiving tray 5 is Since the opening area of the vapor flow path 5d is larger than that of the inner cover vapor passage 7, the pressure inside the inner pot 3 and the gap between the dew condensation receiving tray 5 and the inner lid 4 is almost equal, and the vapor is filled in the dew condensation receiving tray 5 and the inner lid 4. The gap between the six. Further, since the vapor flow path 5d of the dew receiving tray 5 is located at a position that does not face the inner lid vapor passage 7, the vapor is not discharged straight out from the inner lid vapor passage 7, and the vapor is filled in the condensation. The gap 6 between the disk 5 and the inner cover 4 is received. This full steam is opposite to the condensation receiving plate 5-12-200948319 than the lower temperature' and is exposed on the opposite side of the inner cover 4 stomach sputum 5 which is not easily heated, and is dripped and retained in the condensation receiving tray 5 ±. Since the inner lid 4' is not easily heated, the lid heating means does not perform the heating operation, so that the inner lid 4 is continuously dewed and dripped, and stays on the dew receiving tray 5. Finally, when the rice is moved to the boring, the lid heating means 1 is energized to heat the inner lid 4, and the water droplets retained in the dew receiving tray 5 are heated by the inner lid 4 to be vaporized. Since this vapor is released (occluded) by the restriction means 9 as shown in Fig. 3, it cannot be discharged to the outside from the outer cover vapor passage 8, so that the vapor pressure is directed from the vapor flow path 5d of the condensation receiving tray 5 toward the outside. The inner pot 3 is guided to be filled with steam inside the inner pot 3. By doing this, you can make the rice deliciously. In the heat preservation, similarly, the steam generated by the cover heating means 1 is not released to the outside air by the action of the restriction means 9, and is guided from the vapor flow path 5d of the condensation receiving tray 5 toward the inner pot 3. The inside of the inner pot 3 is humidified by steam, and it is possible to keep warm while suppressing the drying of the rice. Moreover, the control of the energization state of the heating means 12 and the lid heating means 10 in the process from the cooking to the warming is by the temperature sensor 13 for detecting the temperature of the inner pot 3, and the temperature sensor 13 The temperature information input of the temperature sensor 13 is input to the control circuit 14. On the other hand, when the outer cover 2 is opened for rice filling, the condensation receiving tray 5 is provided with a bulging portion 5c that protrudes toward the inner lid 4 side, and a plurality of vapor flow paths 5d are provided on the upper surface thereof. Therefore, the dew condensation water retained in the condensation receiving tray 5 -13- 200948319 will drip from the vapor 'flow passage 5d toward the inner pot 3 without damaging the body 1 etc. 'Dew condensation water retained in the condensation receiving tray 5' is made of steam The inside of the inner pot 3 is humidified to effectively suppress the drying of the rice. Further, when the condenser is cleaned and the receiving tray 5 is cleaned, the dew receiving tray 5 is removed from the lower surface of the inner lid 4 for cleaning. The removal of the condensation receiving tray 5 is reversed from the mounting. The lower hook 5f of the upper portion of the condensation receiving tray 5 is pressed downward against the biasing force of the spring 5e, and is removed from the upper receiving member 4c of the inner lid 4. Thereafter, the condensation receiving tray 5 is lifted up and the lower hook portion 5g is removed from the lower receiving member 4d of the inner cover 4. As described above, according to the present embodiment, the vapor generated during cooking is condensed on the inner lid 4, and the dew condensation water is retained as water droplets in the dew receiving tray 5, and the water is used as steam for use in boring and heat preservation. It is not necessary to put the water into the condensation receiving tray 5 before each cooking, as in the prior art, and it is possible to realize an electric cooker which can be cooked and kept warm by steam. Further, since the vapor generated by the condensation receiving tray 5 is not released from the outer cover vapor passage 8 to the outside by the restriction means 9, it is guided in the inner pot 3, and the inner pot 3 can be filled with steam. Thereby, the rice in the inner pot 3 can be fully cooked, and it can be made deliciously. Further, in the heat preservation, although the temperature of the rice is lower than that of the rice, the vapor in the inner pot 3 can be humidified by the vapor in the same manner by the restriction means 9 so that the vapor generated by the lid heating means 1 is not released to the outside air. It can be kept warm while suppressing the drying of rice. And the dew condensation water retained in the condensation receiving tray 5, even if the outer cover 2 is opened for the purpose of filling the rice, it does not drip from the vapor flow path 5 (1 into the inner pot 3 and wet the body - 14-200948319, again When the lid is closed, the inside of the inner pot can be effectively humidified by steam and the drying of the rice can be suppressed.
