Problems solved by technology

In such a structure, since a cable is used to connect the switch and the electronic circuit for judgment, it takes time to install the cable, and it takes time for production, and there is a problem that it is difficult to automate and costly.
[0005] In addition, since the detection part of the pot and the detection part of the water container are different, it is necessary to provide separate judgment circuits, which also has a problem of cost.
[0006] In addition, in the case of small item load detection and no-pot detection based on the correlation between the collector-emitter voltage Vce and the power supply current Iin, induction heating needs to be performed for a certain period of time, and there is a problem that the Useless heating that directly participates in the action of the rice cooker and cannot be detected immediately impairs fitness

no. 1 Embodiment approach

[0023] figure 1 It is a figure which shows the structure of the rice cooker which concerns on 1st Embodiment of this invention.

[0024] like figure 1 As shown, the rice cooker of this embodiment is provided with the pan heating part 3 so that the pan 2 accommodated in the main body 1 may be surrounded.

[0025] The pan heating unit 3 is composed of a plurality of heating units to heat the bottom surface, the upper surface, and the side surfaces of the pan 2 , respectively. The pot heating unit 3 has a plurality of induction heating coils, is installed around the pot 2, and inductively heats each part of the pot 2 to a desired temperature.

[0026] In the rice cooker of this embodiment, the heating part 5 is arrange|positioned so that the water container 6 accommodated in the main body 1 may be surrounded.

[0027] The steam generating unit 10 is composed of the heating unit 5 for heating the water tank 6 and the water tank 6 , and the steam generated by the heating of the ...

no. 2 Embodiment approach

[0047] Hereinafter, the rice cooker which concerns on 2nd Embodiment of this invention is demonstrated. The rice cooker of the second embodiment has substantially the same structure as the rice cooker of the above-mentioned first embodiment, but the difference lies in that the rice cooker of the second embodiment clearly shows small item detection and no-pot detection. And the sequence of water container detection. The rice cooker of the second embodiment is configured to perform operations in consideration of the suitability of the water container detection.

[0048] In the rice cooker of the first embodiment, the sequence of small item detection, no-pot detection, and water container detection is not clearly defined. Since the replacement of the water container 6 is frequently performed, the possibility of forgetting to install the water container 6 is higher than that of forgetting to install the pot 2 . In addition, when small item detection and no-pot detection are prio...

no. 3 Embodiment approach

[0053] Hereinafter, the rice cooker which concerns on 3rd Embodiment of this invention is demonstrated. The rice cooker of the third embodiment has substantially the same structure as the rice cooker of the above-mentioned first embodiment, but the difference lies in that the rice cooker of the third embodiment clearly shows small item detection and no-pot detection. And the sequence of water container detection. The rice cooker according to the third embodiment is configured to perform operations in consideration of the adaptability of small item detection and no-pot detection.

[0054] In the rice cooker of the first embodiment, the order of small item detection, no-pot detection, and water container detection is not clearly defined. Therefore, for example, for reasons such as a large amount of water that can be accommodated in the water container 6, frequent water detection is not performed. Replacement of the container 6, and thus the possibility of forgetting to set the ...

Abstract

The present invention includes: a pot heating unit (3) performing induction heating on a pot (2); a steam generating unit (10) generating steam to be supplied to the pot (2); a water container (6) constituting the steam generating unit (10); and a cover (4) covering an opening portion of the water container (6) and the pot (2). In addition, the present invention includes: a control unit performing rice cooking or warming by performing appropriate heating on a cooking object by controlling the pot heating unit (3) and the steam generating unit (10); and a small object detection unit detecting a small object load or the presence or absence of the pot (2) or the water container (6) during the heating. The small object detection unit detects the installation of the pot (2) and the water container (6) at a predetermined position in a main body (1) by the pot heating unit (3) and the steam generating unit (10) being exclusively controlled.

Description

technical field [0001] The present invention relates to a rice cooker that detects that a container is installed at a predetermined position in a main body. Background technique [0002] In the past, in rice cookers with a steam generating unit, as shown in Japanese Patent No. 3997985, the following proposal has been proposed: for a water container that can be attached to and detached from the main body for the water used in the steam generating unit, reliable The water container is properly arranged to properly generate high-temperature steam, which can suppress unnecessary movement of the steam generating part, and can promote gelatinization and improve rice cooking performance without drying the cooked food. In addition, the rice cooking performance can be improved by eliminating malfunctions and malfunctions caused by forgetting to install the water container that can be attached to and detached from the main body to contain water for the steam generating unit. [0003]...
