Description

TECHNICAL FIELD The present invention relates to a rice cooker used in a general household.

2. Description of the Related Art Conventional rice cookers generally cook rice by adding the prescribed rice and water and setting the heating power and cooking temperature that are considered to be optimal for that rice cooker.

Problems to be Solved by the Invention In such a conventional rice cooker, there has been a problem that the quality of the cooked rice can be standardized regardless of the preference of the user.

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

Means for Solving the Problems In order to solve the above problems, the rice cooker of the present invention comprises a container for containing rice and water, a heating means for heating the container, a heat amount of the heating means for the container, and a rice cooking process. The first remembered
Storage means, second input means for inputting a change amount for arbitrarily changing the amount of heat, second storage means for storing a plurality of the change amounts, and the second storage means for storing the change amount in the second storage means. The amount of heat stored in the first storage means on the basis of the selecting means for selecting an arbitrary amount of change among the amount of change and the second input means, and further executing the rice cooking step to control the heating means. And a control means for controlling the operation.

Action With the above configuration, the amount of heat of the heating means to be applied can be changed, so that the darkness of the charcoal or the hardness of the cooked rice can be changed as desired. Furthermore, since a plurality of variations are stored and an arbitrary variation can be selected from them by the selecting means, it is possible to cook rice according to each taste.

Embodiment One embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a block diagram of a rice cooker according to an embodiment of the present invention. In FIG. 1, 1 is a container for containing rice and water, 2 is heating means for heating the container 1,
3 is a first input means for inputting the start of rice cooking, 4 is a first storage means for storing the amount of heat of the heating means 2 applied to the container 1 and the rice cooking process, and outputting it by the input of the first input means 3. Reference numeral 5 is a second input means for inputting a change amount of heat quantity, 6 is a second storage means for storing a plurality of change quantities input by the second input means 5, and 7 is this second storage means 6 A selection means for selecting an arbitrary change amount from a plurality of change amounts stored in the storage means 8 is stored in the first storage means 4 based on the change amount input by the second input means 5. The heating amount 2 is changed by changing the amount of heat
Is a control means for controlling.

FIG. 2 shows a concrete circuit diagram of the rice cooker in one embodiment of the present invention. In FIG. 2, 10 is a container 1
A heater that heats the heater, 11 a relay that energizes the heater 10, 12 a relay drive unit that drives the relay 11, 13 a change key that changes the amount of change in the amount of heat applied, 14 a plurality of stored changes Select key to select any amount of change, 15 is a start key to start cooking rice, 16 is a container 1
The thermistor for detecting the temperature of 17, the A / D converter for A / D converting the signal of the thermistor 16, 18 is the change key 13, the selection key 14, the start key 15, and the A / D converter 17
And an input unit for inputting the signal of 19; an output unit for opening and closing a contact of the relay 11 to energize the heater 10; and a unit 20 for controlling the output unit 19 by a signal input from the input unit 18. The control unit 21 is a microcomputer including the input unit 18, the output unit 19 and the control unit 20.

FIG. 3 shows a main part of a flow chart of the microcomputer 21, and the operation will be described based on this flow chart.

First, key input is performed in step 31, it is determined whether the key pressed in step 32 is the start key 15, and if not pressed, the process proceeds to step 33 and it is determined whether the key pressed in step 32 is the change key 13. If it is pressed, the change counter is incremented by one rank in step 34. Next, in step 35, it is judged whether or not the variation counter has exceeded a prescribed number, and if it exceeds, the variation counter is initialized in step 36 and the process returns to step 31. If the key pressed in step 33 is not the change key 13, it is judged in step 37 whether the key pressed is the selection key 14, and if it is pressed, the selection counter is incremented by one rank in step 38. . Next, in step 39, it is judged whether or not the selection counter has exceeded a specified number, and if it exceeds, the selection counter is initialized in step 40 and the process returns to step 31. If the key pressed in step 37 is not the selection key 14, it is determined in step 41 whether the key pressed in the selection key 14 and the change key 13 is pressed at the same time. The counter and the selection counter are stored and the process returns to step 31. If no key is pressed in step 41, the process returns to step 31. Step 31 until start key 15 is pressed
To step 42. If the start key 15 is pressed in step 32, proceed to step 43
To cook rice. Next, in step 44, the setting of the amount of heat applied to the container 1 is adjusted based on the amount of change stored in the second storage means. In step 45, the temperature of the container 1 is input from the thermistor 15. In step 46, it is judged whether or not the cooking temperature has been reached. If it has reached, the process proceeds to step 47. If it has not reached, the process returns to step 43 and steps 43 to 46 are repeated. Next, at step 47, the power supply to the heater 10 is stopped. Next, in step 48, the process proceeds to the next step.

From the above operation, change key 13, selection key 14, start key
Since the amount of heat of the heating means 2 applied to the container 1 can be arbitrarily changed and set or stored by means of 15, it is possible to provide the finished rice according to the taste, and by storing a plurality of variations in the amount of heat, various cooked rice can be prepared. You can taste.

Effects of the Invention As described above, the present invention has the following effects.

(1) Since the amount of heat given to the container can be changed, the quality of the rice, such as the darkness of the charcoal and the hardness of the rice, can be customized.

(2) It is possible to provide various kinds of cooked rice because the changed calorie values are memorized and rice can be arbitrarily selected and cooked.

(3) Since rice is selected by selecting from a plurality of stored heat amounts, the operability is improved as compared with the case where the heat amount is changed before cooking rice.
