Abstract

PURPOSE:To simplify operation at the time of rice cooking and improve operating property by receiving the input of a temperature detecting means according to the process of the rice cooking from an external storing means, with an input means, and by setting a control for controlling a heating means. CONSTITUTION:A rice cooker is provided with a vessel 1 for containing rice and water, a temperature detecting means 3 for having a heating means 2 as a means for heating the vessel 1 and detecting a temperature in the vessel 1, an input means 4 for providing the input of the start of rice cooking, and an external storing means 5 for storing the process of the rice cooking and enabling its storing content to be arbitrarily replaced. By a control means 6, with the output of the input means 4, according to the rice cooking process from the external storing means 5, the input of the temperature detecting means 3 is received, and the heating means 2 is controlled. By replacing the replaceable external storing means 5 with an arbitrary rice cooking process, even in a different rice cooking process, by the same simple operation of the input of the rice cooking start signal of the input means 4, the rice can be cooked.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a rice cooker used in general households.

2. Description of the Related Art As shown in FIG. 4, a conventional rice cooker includes a container 41, a heating means 42 for heating the container 41, a temperature detecting means 43 for detecting the temperature of the heated container 41, and a temperature detecting means 43 for starting rice cooking. an input means 44 for inputting a process, a memory means 45 for storing a plurality of prescribed rice cooking processes, a selection means 46 for arbitrarily selecting a process in the memory means 46, and a memory selected by the selection means 46. It has generally been constructed with a control means that controls the heating means 42 to cook rice according to the rice cooking process of the means 46.

Problems to be Solved by the Invention In conventional rice cookers like this, although most of the rice that is cooked every day is the same, it is difficult to operate the rice cooker in order to select the desired rice cooking process from among the multiple stored processes. Input methods such as key switches must be operated in a complicated manner,
There was a problem with poor operability.

An object of the present invention is to provide a rice cooker that solves these problems.

Means for Solving the Problems In order to solve the above problems, the rice cooker of the present invention includes a container for storing rice and water, a heating means for heating the container, and a temperature sensor for detecting the temperature of the heated container. means, an input means for inputting the start of rice cooking, an external storage means that stores the rice cooking process and can arbitrarily replace the stored contents, and the input means! 11. A control means for receiving input from the temperature detection means and controlling the heating means according to the rice cooking process from the external storage means.

Operation With the above structure, by replacing the replaceable external storage means with an arbitrary rice cooking process, rice can be cooked in a different rice cooking process by the same simple operation of inputting a rice cooking start signal to the input means.

Embodiment Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings. FIG. 1 shows a block diagram of a rice cooker according to an embodiment of the present invention. In FIG. It has a temperature detection means 3 for detecting the temperature in the container 1, an input means 4 for inputting the start of rice cooking, and an external storage means 6 for storing the rice cooking process and allowing the stored contents to be replaced at will. , a control means 6 which receives input from the temperature detection means 3 and controls the heating means 2 according to the rice cooking process from the external storage means 6 based on the output from the input means 4;

FIG. 2 shows a specific circuit diagram of a rice cooker according to an embodiment of the present invention. In this FIG. and a relay driving section 12 that drives the relay 11.
are connected to the output section 17. This output section 17 opens and closes the contacts of the relay 11 to energize the heater 10 . a start key 13 for inputting the start of rice cooking;
A thermistor 14 for detecting the temperature of the container 1 and an A/D converter 16 for A/D converting the signal from the thermistor 14 are connected to the input section 1θ, and their respective signals are input. 1) A control unit 19 that controls the output unit 17 according to a signal inputted from the input unit 16 according to the rice cooking process in an external storage unit 18 that stores the rice cooking process and whose stored contents can be replaced arbitrarily. , the input section 16 , and the output section 1
7 and the external storage section 18 constitute a microcomputer 2o.

Thirdly, the main part of the flowchart of the microcomputer 2o is shown, and the operation will be explained based on this flowchart.

First, in step 31, the key is pressed manually, and in step 32, it is determined whether the pressed key is the start key 13, and if it is not pressed, the process returns to step 31. If the start key 13 is pressed, the process advances to step 33 and it is determined whether the external storage section 18 is connected. If the external storage section 18 is not connected, the process returns to step 31 and steps 31 to 33 are repeated until the external storage section 18 is connected and the start key 13 is pressed. When the external storage section 18 is connected and the start key 13 is pressed, the heater 10 is energized in step 34.

Next, in step 36, the temperature of the container 1 is input through the thermistor 14. In step 36, it is determined whether the rice cooking end temperature has been reached, and steps 34 to 38 are repeated until the rice cooking end temperature is reached. When the rice cooking end temperature is reached, the power supply to the heater 1Q is stopped in step 37. After that, the process returns to step 31.

By replacing the p external storage section 18 with the above operation, rice can be cooked in a different rice cooking process simply by pressing the start key 13.

Effects of the Invention As described above, according to the present invention, by storing a large number of rice cooking menus in separate external storage means, the operation during rice cooking is simplified and the operability is improved. In addition, since different rice cooking menus can be provided later, the variety of rice cooking can be increased.
