Description

TECHNICAL FIELD The present invention relates to an automatic rice cooker used in general households.

2. Description of the Related Art Conventional automatic rice cookers that perform a series of operations from washing rice to adjusting water and cooking rice, when the type of rice is set by a switch etc. on the operation unit, the optimum amount of water and the amount of heat for the set rice type are adjusted. It was configured to cook rice.

There are white rice, germinated rice, and brown rice as the types of rice, but it was necessary to set them by operating switches etc. when putting them in rice bins. If this is set incorrectly or forgotten, the amount of water added will be different from the amount of heat added, and this will result in unpleasant rice and can be very unpleasant.

Problems to be Solved by the Invention In such a conventional method, if you forget to set the type of rice put in the rice bin or make a mistake in the setting, the optimum amount of water for the set rice and heating Since it was cooked in, there was a problem that it became poorly cooked rice.

The present invention solves such a problem, and an object of the present invention is to provide an automatic rice cooker that does not need to reset the type of rice each time the rice is replaced.

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention is a rice cooker comprising a pot for heating rice and a heating means, a rice pot that can store rice and discharge it by a predetermined amount, and the discharged rice. A rice washing section for washing rice, a water supply section for supplying water necessary for cooking rice, and a control circuit section for controlling each of these sections are provided, and a rice type discriminating device is provided in the rice pot section.

Effect According to the above configuration, since the type of rice put in the rice bin can be automatically detected and discriminated by the rice type discriminating device, the type of rice must be reset every time the rice in the rice bin is replaced. That inconvenience can be eliminated.

Embodiment An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 shows an overall configuration diagram of an automatic rice cooker according to an embodiment of the present invention. 1 is a pot for cooking rice, 2 is a heating means for heating the pot 1, and 3 is rice. The rice pot part 4 is a rice outlet for discharging a predetermined amount of rice, 5 is a rice washing part for washing the rice discharged from the rice outlet 4, 6 is a rice washing part 5
A transfer part for transferring the rice washed in step 1 to the pan 1, a water tank 7 for storing water necessary for cooking rice, a water supply pump 8 for supplying water to the pan 1, and a water supply 9 for sending water to the pan 1. A pipe, 10 is a water supply nozzle for discharging water to the pan 1, and 11 is a control circuit part for controlling the above-mentioned parts to automatically cook rice.

FIG. 2 is a block diagram of an automatic rice cooker according to an embodiment of the present invention, in which a control circuit 11 includes a control circuit 12, an operation unit 13 for setting the amount of cooked rice and water control, and a display unit. 14 and a storage circuit 15 that stores the type of rice, the amount of rice cooked, and the amount of water added,
It consists of a temperature detector 16 for detecting the temperature of the pot 1.
The rice box 3 is equipped with a rice type discriminating device 17.

FIG. 3 shows an embodiment of a rice species discriminating apparatus 17 using a photointerrupter. This rice species discriminating apparatus 17 has a light emitting diode 18 on the light emitting side due to a difference in light transmittance between brown rice, embryo rice and white rice. The type of rice 20 is determined by utilizing the output change of the phototransistor 19 on the light receiving side that receives the light emitted from the.

Next, the operation will be described with reference to the block diagram of FIG.

First, the control circuit 12 confirms the state of the rice type discrimination device 17,
The type of rice is determined by the light transmittance, and the type of rice set in the memory circuit 15 is written according to the state.

Next, when the amount of cooked rice and the amount of water to be cooked are set through the operation unit 13 and the start switch is pressed, the rice having the set amount of cooked rice is taken out from the rice pot unit 3, washed in the rice washing unit 5, and put into the pot 1.

In addition, the amount of water that matches the set amount of water and the type of rice enters the pan 1 from the water supply unit 8.

When the set amount of cooked rice and the adjusted amount of water are prepared in the pan 1, the heating means 2 heats the pan 1, and the temperature detector 16 detects the temperature of the pan 1 according to the type of water set. Control 2 to complete cooking rice.

All of these series of movements are controlled by the control circuit 12.

EFFECTS OF THE INVENTION As described above, according to the present invention, a rice cooking section comprising a pot for heating rice and a heating means, a rice pot section capable of storing rice and discharging a predetermined amount of rice, and washing rice for washing the discharged rice Department,
It has a water supply section for supplying water necessary for cooking rice and a control circuit section for controlling each of these sections, and since the rice type discriminating device is provided in the rice box portion, the rice type discriminating device firstly When the type of rice is determined according to the type of rice, simply pressing the start switch recalls the determined type of rice from the memory circuit and starts cooking rice. Then, by the series of operations described above, rice will be automatically cooked, and as a result, it is not necessary to reset the rice type every time the rice is replaced, so the operation is easy. It will be rational.
