Abstract

PURPOSE:To carry out the rice cooking in conformity with user's desire by varying the calorific heat memorized in the first memory means and carrying out rice cooking by controlling a heating means after variation quantity inputted from the input means of the second memory means to zero. CONSTITUTION:A heating means 2 heats a container in which rice and water are set. The first memory means 3 memorizes the calorific heat supplied into the container 1 and the rice cooking process, and an input means 4 receives the variation quantity of the calorific heat memorized in the memory means 3. The second memory means 5 memorizes the variation quantity inputted from the input means 4. A control means 6 varies the calorific heat memorized in the memory means 3 on the basis of the variation quantity memorized in the memory means 5, and after variation quantity of the memory means 5 is set to zero, rice cooking is carried out by controlling the heating means 2. Since, in this constitution, the calorific heat supplied into water can be varied by inputting the variation quantity of the calorific heat supplied into the container, the intensity of scorch and the hardness of rice can be changed according to desire. Further, since the variation quantity is set to zero after varying the value of the memory means 3, the rice cooking in conformity with the preceding desire can be carried out in the next rice cooking.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a rice cooker for general household use.

BACKGROUND OF THE INVENTION Conventional rice cookers generally cook rice by adding a specified amount of rice and water and setting the heat and cooking temperature that are considered optimal for the rice.

Problems to be Solved by the Invention The conventional rice cooker as described above has a problem in that the rice can only be cooked in a uniform manner regardless of the user's preference.

An object of the present invention is to solve the above-mentioned problems and provide a rice cooker that can cook rice according to the user's preference.

Means for Solving the Problems In order to achieve the above object, the present invention stores a container for holding rice and water, a heating means for heating the container, an amount of heat to be applied to the container, and a rice cooking process. a first storage means; a human power means for inputting the amount of change in the amount of heat stored in the first storage means; a second storage means for storing the amount of change input by the human power means; The amount of heat stored in the first storage means is changed based on the amount of change stored in the second storage means, and the amount of change in the second storage means is made zero, and then the heating means is controlled to cook the rice. This rice cooker consists of a control means to

Effect: With the above configuration, the amount of heat given to the water can be changed by inputting the amount of change in the amount of heat given to the container, so the depth of scorch and the hardness of the rice can be changed according to preference. Furthermore, the first storage means is changed based on the information in the second storage means that stores the amount of change, and then the amount of change is made zero, so that the next time the rice is cooked, the rice will be cooked according to the previous taste. can be done.

Embodiment Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings.

Figure 1 shows a block diagram of a rice cooker according to an embodiment of the present invention. In Figure 1, 1 is a container for storing rice and water, and 2 is a heating means that performs heater or induction heating. The container 1 is heated using a heating coil or the like. 3 is a first storage means that stores the rice cooking process and the cooking temperature. Reference numeral 4 denotes an input means for inputting the amount of change in the cooking temperature stored in the first storage means 3. 5 is the second
The storage means stores the amount of change inputted by the input means 4. Reference numeral 6 denotes a control means that changes the amount of heat stored in the first storage means 3 based on the amount of change stored in the second storage means 5, and makes the amount of change in the second storage means 5 zero. After that, the heating means 2 is controlled to cook the rice.

FIG. 2 shows a specific circuit diagram of a rice cooker according to an embodiment of the present invention. In FIG. 2, 7 is a heater that heats the container l. 8 is a relay that supplies electricity to the heater 7. Reference numeral 9 denotes a relay drive unit that drives the relay 8. 1O increases the amount of change in cooking temperature using the UP key.

11 is the DOWN key to decrease the amount of change in cooking temperature. A thermistor 12 detects the temperature of the container 1.

+3 is the A/D converter and the thermistor! 2 signal is A/D converted. 14 is an input section, and the UP key 10
And said DOWN key 1! Then, the signal from the A/D converter 13 is input. Reference numeral 15 denotes an output section, which opens and closes the contacts of the relay 8 to energize the heater 7. Reference numeral 16 denotes a control section, which controls the output section 15 according to a signal input from the input section 14. A microcomputer 17 includes the input section 14, the output section 15, and the control section 15.

FIG. 3 shows the main part of the flowchart of the microcomputer 17, and the operation will be explained based on this flowchart.

First, perform key human power in step 18, and step 19
It is determined whether the pressed key is the UP key 10, and if it has been pressed, the change amount counter is increased by one rank in step 20. If the tJP key IO is not pressed in step 19, the process advances to step 21.

In step 21, it is determined whether the pressed key is the DOWN key II, and if it has been pressed, the change I counter is decreased by one rank in step 22. DO in step 21
If WN key 11 is not pressed, step 23
Proceed to cooking rice.

If the counter is increased or decreased in steps 20 and 22, the process proceeds to step 23 and the heater 7 is controlled to cook rice.Next, in step 24, the amount of change stored in the second storage means 5 is used to change the amount of rice into the container 1. Adjust the heat setting. In step 25, the temperature of the container l is manually controlled using the thermistor 12.

In step 2, determine whether the cooking temperature adjusted in step 24 has been reached.

If the amount of heat has been reached, the process proceeds to step 27; if the amount of heat has not been reached, the process returns to step 18, and the steps from step I8 to step 26 are repeated.Next, in step 27, the amount of heat given to the container l stored in the first storage means 3 is changed to the second value. The change is made according to the amount of change stored in the storage means 5. In step 2B, the amount of change in the second storage means 5 is made zero.

In step 29, the power supply to the heater 7 is stopped. Next, in step 30, the process proceeds to the next process.

Through the above operations, the amount of heat given to the container l can be arbitrarily changed and set using the UP key 0 and the DOWN key 11, so the rice can be prepared to suit your taste.
The next time the rice is cooked, the result will be the same as the first time without changing the cooking temperature again.

Effects of the Invention As described above, according to the present invention, by changing the amount of heat given to the container and adjusting the firepower, it is possible to cook rice according to the user's preference, and the result is now uniform. It offers a variety of flavors.
