Embodiment 1

[0090] first pass Figure 1 to Figure 8 To describe the electric rice cooker in Embodiment 1 of the present invention.

[0091] 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.

[0092] figure 1 Among 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 mann...

Embodiment 2

[0165] Use Figure 9~ Figure 11 To illustrate the electric rice cooker in Embodiment 2 of the present invention.

[0166] Fig. 9 is a partially cut side view of the electric rice cooker in Embodiment 2 of the present invention, wherein 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.

[0167]In Fig. 9, 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 detachable manner, the flange 121 is in a s...

Embodiment 3

[0196] 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 (Fig. 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.

[0197] Three guide roller installation mechanisms 63 are equally arranged on the upper end opening portion of the upper frame 61 . The guide roller 70 is...

Abstract

The rice cooker of the invention includes a body with an open on the top surface, a pot in the body, a lid covering the body open section, a heating means for heating the pot, a weight detecting element mounted on the body for detecting the total weight of the pot and the cooked food, a rewritable non-volatile memory and a control unit for updating a weight computing parameter stored in a storage unit on the basis of an output signal of the weight detecting means at a first time, computing the weight of the cooked food on the basis of the output signal of the weight detecting means and the weight computing parameter at a second time and controlling the percentage of current carried and / or the amount of current carried by the heating means in accordance with the weight of the cooked food. The non-volatile memory has a storage unit for storing at least a first output signal of the weight detecting means when the pot is not in the body and a second output signal of the weight detecting means when the pot is in the body.

Description

[0001] This application is a divisional application of the invention patent application with the application number "200410088264.3" and the invention name "electric rice cooker" submitted by the applicant on October 18, 2004. technical field [0002] The invention relates to an electric rice cooker. Background technique [0003] 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. [0004] 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...
