Referring to the operating state of the unmanned automatic cooker provided as described above are as follows.

When the number of servings suitable for the number of people is input by a program located on one side of the main body 1, the feed motor rotates in one direction and the feed screw 40 is rotated at the same speed by being engaged with the rotational speed of the motor. The rice 4 accumulated between the blade 41 and the blade 41 is transferred upward by the rotation of the screw and is ejected to the inside of the water tank through the ejection hole 7. 4) is injected into the inside of the feed screw 40 through the injection hole (6) from the rice container (3) is provided between the blade 41 and the blade 41 of the screw at all times provided that the rice 4 is full The amount of the rice 4 ejected into the ball 7 is provided to be uniformly ejected in proportion to the rotational speed of the motor to prevent the amount of the rice 4 from occurring.

When the appropriate amount of rice 4 is introduced into the washing unit 10 as described above, the transfer motor stops the operation and water (W) is injected into the washing unit 10 from the outside. From the water supply solenoid valve 33 located on the upper side of the main body 1 from the oil is introduced into the filter 31, and after the primary washing to purify the water (W) through the water filter configured inside the filter 31 Water W is supplied to the cleaning unit 10 through the water supply hole 35 through the flow control sensor 30 and passes from the flow control sensor 30 to adjust the amount of water (W). When the appropriate amount of water (W) is introduced by checking the amount of water (W) is to send a signal to the water supply solenoid valve 33 to block the injection of water (W).

When the appropriate amount of water (W) flows into the washing unit 10 as described above, the first motor M1 located above the main body 1 is driven, and the stirring shaft is driven by the first motor M1. (12) is rotated left and right to rotate the stirring blade 13 located in the lower portion of the stirring shaft 12 to the left and right several times to wash the rice (4) and water (W) of the washing section 10 first When the rotary motor is stopped, the drain solenoid valve 39 is opened so that the water (W) in the lower part of the washing unit 10 is discharged to the outside through the network located on one side of the inclined portion (11). After a predetermined time has elapsed so that the water (W) can be completely discharged, the drain solenoid valve (39) is closed, and the water (W) flows again from the outside to repeat the washing operation and the flow rate control sensor (30) detects it. After the appropriate amount of water (W) to be introduced into the interior of the washing unit 10 to drive the second washing operation after the water (W) It is to be discharged to the outside.

In order to transfer the rice 4 sufficiently washed several times in the same manner as described above to the rice cooker 2, an appropriate amount of water W is detected into the washing unit 10 by sensing the flow control sensor 30. The water supply unit has a plurality of bottom surfaces and outer circumferences of the water supply pipe 34 so that water (W) is evenly sprayed 360 degrees in order to collect the rice 4 spreading on the bottom surface of the washing unit 10 to the lower center. Water supply hole 35 is configured to the water (W) is discharged to the water supply hole 35 is to collect the water (W) and the rice (4) in the lower portion of the washing unit (10).

The water (W) and the rice (4) collected at the bottom of the center as described above to raise the stirring shaft (12) in order to be guided to the water hole 16 of the cooker 2 through the water port (14) The fixing pin 25 located on the upper side of the 22 is moved inward by the driving of the solenoid 24 to be engaged with the spiral groove 21 of the stirring shaft 12 so as to be connected to the stirring shaft 12. When the motor M1 is driven, the stirring shaft 12 rotates, and the fixing pin 25 is engaged with the spiral groove 21 so that the stirring shaft 12 rises in the direction of the spiral groove 21 to lower the lower end of the stirring shaft 12. Sealing packing 15 and the drain 14 located in the separation is moved to the upper side and the drain 14 is open so that the water (W) and the rice (4) at the same time from the drain 14 to the top of the rice cooker (2) It will flow down into the repair hole (16).

As described above, in order for water (W) and rice 4 to smoothly flow into the inside of the rice cooker 2 through the water hole 16, the diameter of the water hole 16 is larger than the outer diameter of the water port 14. The water supply 16 of the rice cooker 2 provided with water (W) and rice 4 from the washing unit 10 is provided with a blocking plate 17 on the upper side in a sliding manner to rotate the rice cooker 2. ), The rice 4 is cooked in a sealed state, and when cooking is completed, the third motor M3 located at the bottom of the rice cooker 2 operates to operate the rack gear 51 provided at the bottom of the support plate 52. The pinion gear 50 associated with the third motor M3 rotates at the same speed to pull the rack gear 51 so that the support plate 52 and the rice cooker 2 are drawn out to the front part of the main body 1 and the rice cooker 2 It will be provided to take out the rice from the) to describe an embodiment of the drive system of the stirring shaft 12 that can be used simultaneously with the present invention as follows.

(Example 1)

The fourth motor (M4) is coupled to the guide rod 23 located on the upper side of the stirring shaft 12 is driven by the encoder-type motor of the fixing jaw (60) provided on the upper side of the bracket (22) The upper and lower parts are provided with a sensing sensor part 62, and in the center of the fixed jaw 60, a separate operating member 61 is fastened to the stirring shaft 12, and the fourth motor M4 rotates in one direction to fix the fixed jaw. The operating member 61 located at the lower side of the 60 is moved to the upper side, and the fourth motor M4 is rotated in the reverse direction when the upper side is in contact with the upper sensing sensor unit 62 to move the operating member 61 to the lower side. When the operating member 61 is in contact with the lower sensor 62, the fourth motor (M4) is rotated in the reverse direction again.

After washing the rice 4 inside the washing unit 10 by rotating the stirring shaft 12 from side to side using a motor capable of forward and reverse rotation as described above, the water (W) and the rice (4) with a rice cooker (2). In order to raise the stirring shaft 12 by raising the stirring shaft 12 in order to send the operating member 61 is raised together with the stirring shaft 12 by rotating the fourth motor M4 in one direction. By continuously rotating without reverse rotation when contacting the upper sensing sensor unit, the operating member 61 stops at the upper side of the fixing jaw 60 and the stirring shaft 12 is raised to open the water port 14. When closing, drive in the reverse order.
