In addition, the rice cooker 200 for cooking and keeping the semi-heated rice is a key input unit 202 for setting the overall operation of the rice cooker, and photo-coupler (PC1) (PC2) through the cooking and information on the cooking device ( 100 is transmitted to the microprocessor 201 for controlling the overall operation of the rice cooker 200 due to the key input of the key input unit 202, and the power supply unit 105 receives a switching signal output from the microprocessor 201 A relay (RY1) (RY2) (RY3) for supplying / blocking power supplied to each heater 206, 107, and 208 via the fuse F in the air, and a temperature sensor for sensing an internal temperature of the rice cooker. 204 and a rice cooker presence sensor 205 for detecting an endothelial seating state inside the rice cooker.

Here, the hot plate heater 206 of the plurality of heaters 206, 207, 208 is installed on the bottom of the rice cooker to serve to heat the bottom surface of the rice cooker, body heater 207 is Is provided in the annular body of the cooker, the lid heater 208 is also installed on the lid of the cooker to prevent dew condensation at the end of cooking or warming.

In the conventional automatic cooker configured as described above, when the cooking amount to be cooked by the operation of the key input unit 107 is set, the weight of the rice fed from the rice container 101 by the metering unit 102 is improved, and the weight data thereof is micro Supplied to the processor 106. That is, the microprocessor 106 receives the weight data applied from the weighing unit 102 to sense the amount of rice introduced from the rice container 101, and the amount of rice introduced is cooked by the operation of the key input unit 107. Adjust the input of rice so that it is a quantity (referred to as rice).

Subsequently, the introduced rice is transferred to the semi part 104, and then semi-operated by water supplied from the outside, and then introduced into the rice cooker of the rice cooker part 200.

Next, the microprocessor 201 that controls the operation of the rice cooker 200 has a specific cooking mode (such as jinbab, ordinary rice, pork rice, grain rice, porridge, etc.) or a warming mode set by the operation of the key input unit 202. Determine if it is possible. When the cooking mode of the specific mode is set, the cooker presence sensor 205 determines whether the endothelial is normally mounted in the inside of the cooker, and generates a switching signal to perform the set cooking function when the inner shell is normally seated. The power supply unit 105 is supplied to each of the heaters 206, 207, and 208 through the fuse F, because the power is supplied to the relays RY1, RY2, and RY3.

Therefore, due to the heat generated by the heaters 206, 207, and 208 installed on the bottom, the body, and the lid of the rice cooker, the rice including the endothelium is heated to perform a normal cooking function. This cooking function and further warming function is made to correspond to the operation of the key input, it is made the same as the cooking operation or the warming operation of the general electric rice cooker.

Pressurized cap to increase the pressure of the water supplied to the unit 17 It is configured to further comprise a 18.

Here, when the water pressure detected by the water level sensor of the flow rate unit 19 exceeds the maximum pressure, the solenoid valve of the flow rate unit 19 is operated to block the water supply. In addition, the oil flow rate unit 19 has a use range ( And a solenoid valve which is opened and closed under the control of the microprocessor 15, a constant flow valve that constantly adjusts the water pressure of the water flowing from the water supply 20, and detects the pressure of the incoming water and receives a corresponding signal corresponding thereto. The microprocessor 15 is composed of a singular sensor.

16, which is not described in the drawings, is a timer IC for providing time data to the microprocessor 15, and 21 is a display unit for displaying the overall operating state of the automatic cooker.

Figure 3 is a flow chart showing the operating state of the automatic cooker according to the present invention, the process of determining whether the automatic cooker is in operation, and if the water is supplied from the hydrant by the single-stage sensor of the constant flow rate unit when the automatic cooker is in operation If the water is not supplied in the process of determining the number of stages and if the water is supplied in the process of determining whether the water pressure detected by the water flow sensor of the constant flow rate is above a certain pressure, and if the water pressure is above a certain pressure It is shown that the normal operation is received by receiving the water supplied, and if it is below, the normal pressure is operated to increase the water pressure to perform the normal operation.

According to the present invention configured as described above, when the cooking quantity (usually set to 1 serving, 2 servings, 3 servings, etc.) to be cooked by the operation of the key input unit is not shown, the metering unit 11 is provided from the rice container 10. The weight of the introduced rice is improved and the weight data for this is supplied to the microprocessor 15. That is, the microprocessor 15 receives the weight data applied from the weighing unit 11 to sense the amount of rice to be input from the rice container 10, and the amount of rice to be introduced is set by the manipulation of the key input unit (rice Adjust the input of rice so that the amount of).

When the discharging operation is finished, the rice discharged from the rice container 10 is transferred to the semi-part 17 and is put into the rice cooker after the semi-operation is made by water supplied from the outside.

At this time, the pressurizing motor 18 and the constant flow rate unit 19 operate by the control signal output from the microprocessor 15 so that the water flowing from the water supply 20 is supplied to the semi part 17.

Here, the solenoid valve of the constant flow rate unit 19 receives the open / close signal output from the microprocessor 15 to supply the water supplied from the water supply 20 to the pressurizing motor 18, and the constant flow valve is the water supply 20 By adjusting the amount of water supplied from the) to adjust the amount of water so that a certain amount of water is supplied to the semi-part 17 via the pressure motor 18 for a predetermined time.

In addition, since the water level sensor of the flow rate unit 19 detects the pressure of the water supplied from the water supply 20 and supplies it to the microprocessor 15, the pressurized motor 18 is controlled under the control of the microprocessor 15 that is applied thereto. In operation, the semi-part 17 is always supplied with water of a constant pressure. In particular, when there is no water supplied from the water supply 20 by the single stage sensor of the flow rate unit 19, the microprocessor 15 operates the display unit 21 to inform that the current single stage is present and at the same time, the semi unit 17 Stop the operation of the automatic cooker, including) so that the automatic cooker does not operate without the water supply.

Subsequently, after the semi-operated rice is put into the rice cooker and before executing a specific cooking mode set by key input, it is judged whether the endothelial is normally mounted in the inside of the rice cooker by the rice cooker presence sensor, which is not shown. If present, the switching signal is generated and supplied to each relay so as to perform the set cooking function, so that the power supplied from the power supply unit 13 is supplied to each heater.

Therefore, the rice, including the endothelium is heated by the heat generated by the heater installed on the bottom and the body and the lid of the cooker performs a cooking function. This cooking function or warming function is made to correspond to the operation of the key input, the same as the operation of the general electric rice cooker.

The operation state of the automatic cooker is displayed by operating the display unit 21 under the control of the microprocessor 15, so that the operation state of the automatic cooker can be confirmed.

Referring to Figure 3 in more detail the operation of the automatic cooker as described above are as follows.

First, the microprocessor 15 determines whether the automatic cooker is in a standby state or in operation (S1).

When it is determined that the automatic cooker is in operation, it is determined whether the water is supplied from the water supply 20 by the water level sensor of the oil refiner 19 (S2). That is, by detecting the pressure of the water flowing into the pressurization motor 18 from the water supply 20, the water pressure is a constant pressure (approximately If it is less than or equal to) it is recognized that the water is not supplied to the water to generate a drive signal to display the display 21 so that the display unit 21 operates to prevent the water supply from the current water supply 20 Informs the presence (S3).

However, the pressure of the water detected by the single stage sensor of the flow rate unit 19 is constant pressure (approximately If the water pressure is higher than the water level detected by the water level sensor of the constant flow rate unit 19, the automatic cooker including the semi-part 17 is operated normally by a constant pressure (here, the constant pressure means water pressure). It is determined that the water pressure that can not be detected) or less (S4).

If the water pressure is detected above a certain pressure, the normal operation is performed. The water pressure is below a certain pressure. In the case of being detected, the automatic cooker cannot operate normally at the pressure of the water supplied, and outputs a driving signal to the pressurized motor 18 to increase the pressure of the inflowing water. The pressure of the water supplied to the) to have a constant pressure to perform the semi-operation, cooking and warming operation to normal (S6).

Thereby, the pressure of the water supplied from the water supply 20 to the semi part 17 can be adjusted uniformly.

As described above, the present invention detects the pressure of the water flowing in by using the single stage sensor of the constant flow rate, and when the water pressure is detected below the predetermined pressure, by operating the pressurized motor to increase the water pressure to a certain pressure, the automatic cooker The amount of water supplied to the semi section of the can be adjusted constantly.

In addition, the present invention can prevent the semi-operation, the cooking operation and the warm-up operation in the state that the water is not supplied from the outside by stopping the operation of the automatic cooker, including the semi portion in the state that the water is not water supply, It is possible to know that the water supplied to the automatic cooker is in the singular state by operating the display unit when the water is cut.
