Example Embodiment

[0015] (Example 1)

[0016] Fig. 1 shows an electric rice cooker in embodiment 1 of the present invention.

[0017] As shown in FIG. 1, the pot body 11 is slightly cylindrical, with an opening on its upper surface, and an upper frame 12 is embedded in the opening part. The upper frame 12 and the coil base 13 form a receiving cavity for the pot 14 inside the pot body 11. The coil base 13 is formed into a cylindrical shape with a bottom, and its upper end is fixed to the upper frame 12. In addition, a pot bottom induction coil for induction heating the pot 14 is provided on the coil base 13 to constitute a pot heating device 15 to perform induction heating on the pot 14.

[0018] The bottom sensor 16 for detecting the temperature of the pot 14 is installed to hold the bottom surface of the pot 14 with elastic force to detect the temperature of the pot during rice cooking and heat preservation, so as to keep the cooking objects in the pot 14 at the optimal temperature on.

[0032] (Example 2)

[0033] Figure 2 is an electric rice cooker in embodiment 2 of the present invention. Among them, for the same constituent elements as in Embodiment 1, only the same symbols are marked here, and repeated descriptions thereof are omitted, and the description is focused on the differences.

[0034] As shown in FIG. 2, the rice cooker of the second embodiment is provided with a steam heating unit 20c for increasing the temperature of the steam generated in the steam generating unit 20a on the lid heating plate 20, at a temperature corresponding to the steam heating unit 20c The second cover heating device 30 is also provided in the position. The second cover heating device 30 is controlled by a second cover heating control device (not shown in the figure).

[0035] The operation and function of the rice cooker with the above-mentioned configuration will be described below.

Example Embodiment

[0039] (Example 3)

[0040] Hereinafter, Embodiment 3 of the present invention will be described with reference to FIGS. 1 and 2.

[0041] In the rice cooker of this embodiment, the steam generating unit 20a for storing water supplied from the water container 19 and generating steam is provided in such a way that it is located on the pivot 18 supporting the lid 17 and the steam generating unit 20a The position between the steam injection port 20b communicating with the inside of the pot 14.

[0042] When performing rice cooking operations, the user first fills the pot 14 with rice and water, and prepares a prescribed amount of water in the water container 19, then installs the pot 14 and the water container 19 into the rice cooker, and turns on the power of the rice cooker; Press the rice cooking start button to execute the rice cooking operation. After the rice cooking operation is completed, it will enter the heat preservation step. In the heat preservation process, the water in...

Abstract

The invention provides an electric rice cooker capable of preventing the rice from becoming dry and sticky due to heat preservation, which comprises: a pot (14); a pot heating device (15); a pot cover (17); A lid heating plate (20) for heating; a lid heating device (23) for heating the lid heating plate; a water container (19) for storing water supplied to the lid heating plate; and adding water from the water container to the lid heating plate The water adding device (25). The cover heating plate is provided with: a steam generating unit (20a) for storing water supplied from a water container (19) and making the water generate steam; Inject into the steam injection port (20b) in the pot. In this way, only an amount of water corresponding to the required amount of steam can be supplied from the water container to the steam generating unit on the lid heating plate, and the dryness and stickiness of the rice caused by heat preservation and heating can be prevented.

Description

technical field [0001] The invention relates to an electric rice cooker for keeping rice warm through steam. Background technique [0002] In existing electric rice cookers, in order to prevent the rice that is kept from drying out, some produce steam by heating the water in the water tank, and then steam is discharged into the pot (one example thereof can refer to the Japanese Patent Laid-Open Publication). 2004-57545). [0003] But, adopt above-mentioned conventional device structure, in order to discharge steam in the pot, need to carry out intermittent heating to water tank, for example, with certain time interval, thereby the water in the water tank is heated. However, since all the water in the water tank is heated every time, it is difficult to finely control the amount of steam discharged into the pot. Therefore, when the amount of steam discharged is small, the rice appears dry, and when the amount of steam is large, the rice appears dry again. sticky problem. C...
