Problems solved by technology

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

Embodiment 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 roughly cylindrical, with an opening on its upper surface, and an upper frame 12 is inlaid on the opening. The upper frame 12 and the coil seat 13 form an accommodating cavity of the pot 14 inside the pot body 11 . The coil base 13 is formed into a bottomed cylindrical shape, and its upper end is fixed to the upper frame 12 . In addition, a pan bottom induction coil for inductively heating the pan 14 is provided on the coil base 13 to form a pan heating device 15 for inductively heating the pan 14 .

[0018] The pot bottom sensor 16 used to detect the temperature of the pot 14 is installed to withstand the bottom surface of the pot 14 by elastic force, and detects the temperature of the pot when cooking and keeping warm, so as to keep the cooking material in the pot 14 at the optimum temperature superior.

[0019] The pot cover 17 is support...

Embodiment 2

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

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

[0035] The operation and effect of the electric rice cooker having the above-mentioned constitution will be described below.

[0036] When cooking rice, the user first loads rice and water into the pot 14, and prepares a specified amount ...

Embodiment 3

[0040] Embodiment 3 of the present invention will be described below with reference to FIG. 1 and FIG. 2 .

[0041] In the rice cooker of the present embodiment, the steam generating unit 20a for storing the water supplied from the water container 19 and generating steam is arranged so that the steam generating unit 20a is positioned between the pivot shaft 18 supporting the lid 17 and the steam generating unit 20a. It is at a position between the steam injection port 20b communicating with the inside of the pot 14.

[0042] When cooking rice, the user first loads rice and water into the pot 14, and prepares a specified amount of water in the water container 19, then puts the pot 14 and the water container 19 in the rice cooker, and turns on the power of the rice cooker; then, Press the rice cooking start button to perform the rice cooking operation, and enter the heat preservation step after the rice cooking operation is completed. During the heat preservation process, the w...

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...
