Abstract

PURPOSE:To permit the rice cooking in conformity with user's desire by changing the cooking-up temperature memorized in the first memory means and carrying out rice cooking by controlling a heating means after variation quantity inputted by the input means of the second memory means to zero. CONSTITUTION:The first memory means 3 memorizes the rice cooking process and the cooking-up temperature. An input means 4 receives the variation quantity of the cooking-up temperature memorized in a memory means 34, and the second memory means 5 memorizes the variation quantity inputted from the input means 4. A control means 6 changes the cooking-up temperature which is 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, the rice cooking is carried out by controlling a heating means 2. Since, in this constitution, the cooking-up temperature can be changed by inputting the variation quantity of the cooking-up temperature, the degree of scorch and hardness of rice can be changed according to desire. Further, since the variation quantity is set to zero after memory means 3 is changed, the rice cooking in conformity with the desire in the preceding time can be carried out in the next cooking.

Description

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

Conventional technology In conventional rice cookers, it was common for rice to be cooked by adding the specified amount of rice and water and setting the heat and cooking temperature that would be optimal for that rice.The invention solved the problem. 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.

The purpose of the present invention is to solve the above-mentioned problems.

The purpose is to 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 objects, the present invention provides a container for holding rice and water, a heating means for heating the container, and a storage device that stores the rice cooking process and the cooking temperature. 1 storage means, an input means for inputting the amount of change in the cooking temperature stored in the first storage means, a second storage means for storing the amount of change input by the input means; The cooking temperature 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. This rice cooker consists of a control means for cooking rice.

Effect: With the above configuration, the rice cooking temperature can be changed by inputting the amount of change in the cooking temperature, so the degree of charring and the hardness of the rice can be changed to suit your preference. Furthermore, the first storage means is changed based on the information in the second storage means that stores the amount of change, and 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 cooking temperature stored in the first storage means 3 based on the amount of change stored in the second storage means 5, and controls the amount of change in the second storage means 5. After the temperature is reduced to zero, 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 1. 8 is a relay that supplies electricity to the heater 7. Reference numeral 9 denotes a relay drive unit that drives the relay 8. 10 increases the amount of change in cooking temperature using the UP key.

1) Use the DOWN key to decrease the amount of change in cooking temperature. +2 is a thermistor that detects the temperature of the container l.

+3 is an A/D converter which A/D converts the signal of the thermistor +2. 14 is an input section, and the UP key lO
, the DOWN key 1) and the signal from the A/D converter 13 are input. 15 is an output section that opens and closes the contacts of the relay 8 to energize the heater 7; 16 is a control section that controls the output section 15 according to a signal input from the input section 14; Reference numeral 17 denotes a microcomputer, which is comprised of the input section 14, the output section 15, and the control section 6.

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 UP key 10 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 (■), and if it has been pressed, the change amount counter is decreased by one rank in step 22. DOW in step 21
If the N key 1) has not been pressed, proceed to step 23, cooking rice.

If the counter is increased or decreased in step 20.22, the process proceeds to step 23 and the heater 7 is controlled to cook the rice.Next, in step 24, the cooking temperature is determined based on the amount of change stored in the second storage means 5. Adjust settings. Step 25
The temperature of the container L is input from the thermistor 12. In step 26, it is determined whether the cooking temperature adjusted in step 24 has been reached. If it has been reached, proceed to step 27; if it has not been reached, proceed to step 18, and repeat from step 18 to step 26. Next, proceed to step 27. The cooking temperature stored in the first storage means 3 is changed according to the amount of change stored in the second storage means 5. In step 28, 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.Then, in step 30, the process proceeds to the next step.

From the above operation, UP key lO and D OV/N
Since you can arbitrarily change and set the cooking temperature for finishing rice cooking using key 1), you can provide the finished rice that suits your tastes without having to change the cooking temperature again from the first time. The result will be similar to that.

Effects of the Invention As described above, according to the present invention, by changing the temperature at which the rice is cooked, it is possible to change the cooking state according to the user's preference, which eliminates the uniformity of the rice that has been produced up to now. They offer a variety of different tastes.
