Embodiment 1

[0089] first pass Figure 1 to Figure 8 To describe the electric rice cooker in Embodiment 1 of the present invention.

[0090] The structure of the electric cooker in embodiment 1 is as figure 1 and figure 2 shown in . figure 1 It is a partially cut-away side view of the electric rice cooker in Example 1 of the present invention. The part that is cut is shown in a cross-sectional view. For the sake of brevity in the drawing, components such as electrical connecting wires are omitted.

[0091] figure 1Among them, 10 is the box-shaped cooking pot body of electric rice cooker. The pot body 10 is provided with a pot cover 20 that covers its upper surface and can be opened and closed freely. The pot cavity 30 in the pot body 10 is composed of an upper frame 32 above and a coil base (coil support) 31 below. The pot 12 is made of magnetic materials such as stainless steel and iron, and this pot 12 made of a magnetic body is installed in the pot cavity 30 in a detachable man...

Embodiment 2

[0164] Use below Figure 9 ~ Figure 11 To illustrate the rice cooker in Embodiment 2 of the present invention.

[0165] Figure 9 It is a side view of the electric rice cooker in Embodiment 2 of the present invention after being partially cut off, and the cut part is represented by a cross-sectional view. In order to make the drawing simple, the electrical connecting wires and other components are omitted.

[0166] exist Figure 9Among them, 10a is a box-shaped pot body of an electric rice cooker, and the pot body 10a is provided with a pot cover 20a that covers its upper surface and can be opened and closed freely. The pot cavity 30a of the pot body 10a is composed of an upper frame 32a above and a coil base (coil supporting member) 31a below. The pot 12a is made of magnetic materials such as stainless steel and iron. The upper opening of the pot 12a is provided with a protruding edge 121 protruding outward. When the pot 12a is placed in the pot cavity 30a in a detachab...

Embodiment 3

[0195] Use below Figure 12 to Figure 14 To describe the electric rice cooker in Embodiment 3 of the present invention. In the rice cooker in Embodiment 3, the upper frame 32a of the rice cooker in Embodiment 2 is replaced by the upper frame 61 , and a guide roller 70 is added to the upper opening of the upper frame 61 . Because except the structure of the upper end opening part of upper frame 61 and the electric cooker among the embodiment 2 ( Figure 9 ~ Figure 11 ) are the same, therefore, the same symbols are assigned to the same components, and repeated description thereof will be omitted. Figure 12 It is a plan view of the electric rice cooker in Embodiment 3 of the present invention. Figure 13 It is an exploded perspective view of a partial structure of an electric rice cooker in Example 3 of the present invention.

[0196] Three guide roller installation mechanisms 63 are equally arranged on the upper end opening portion of the upper frame 61 . The guide roller 7...

Abstract

The rice cooker has a body, the top of which is opened, a pot removably stored in the storage section of the body, a lid openably covering the storage section, an induction heating means for induction heating the pot, a weight sensing element directly or indirectly mounted to the storage portion and a sensor directly or indirectly mounted to the weight sensing element and abutting against the near center of the outside bottom of the pot. The rice cooker also has a weight sensing means for sensing the total weight of the pan and the object of cooking put in the pot by the weight sensing element through the sensor and a control section computing the weight of the object of cooking on the basis of an output signal of the weight sensing means and controlling the percentage of current carried and / or the amount of current carried by the induction heating means in accordance with the weight of the object of cooking.

Description

technical field [0001] The invention relates to an electric rice cooker. Background technique [0002] In recent years, more and more electric rice cookers using electromagnetic induction for heating are on the market. In such a rice cooker (induction heating rice cooker) for heating by electromagnetic induction, an induction heating coil is provided on the outside of the bottom of the pot, and the pot itself is heated by a magnetic field generated from the induction heating coil. Come, it can be cooked into softer and more delicious rice. [0003] On the other hand, in order to improve the taste of rice, electric rice cookers that first judge the amount of rice and water (cooked rice amount) in the pot, and then control the heating amount according to the amount of cooked rice have also been popularized. [0004] Japanese Patent Application Laid-Open No. 2002-10910 shows an electric rice cooker which can be the first prior art of the present invention. In this kind of ri...
