A rice washing screw chamber 182 having a suction port is connected to the lower end of 81. A rice washing screw 184 attached to the shaft 183 is provided in the rice washing screw chamber 182, and the rice washing screw 184 is driven by a motor 185.

A cylindrical net 186 capable of forward and reverse rotation is provided at the upper end outlet of the circulation pipe 181. On the left side of the cylindrical net 186, the lower end can be seen the upper end of the pipe 187 connected to the rice washing tank 180, and on the right side, the rice discharge path 188. further,
A discharge port 189 of the water supply pipe is provided above the rice discharge channel 188.

Reference numeral 190 is a water absorption pipe that absorbs water in order to adjust the amount of water in the pot a, and its water supply port is surrounded by a net 191 so that only water is sucked and rice is not sucked. This water absorption pipe 190 is
Connect to siphon pipe 192.

The siphon pipe 192 is provided with a suction fan 194 driven by a motor 193 at its upper end, and a pressure sensor 195 for detecting the pressure in the pipe immediately below the fan 194. The lower end of the siphon pipe 192 is arranged in the siphon receiving tank 196.

The discharge port of the overflow pipe 199 provided in the rice washing tank 180 is connected to the upper portion of the siphon receiving tank 196, and the discharge pipe 197 is connected to the upper portion. Also, rice washing tank 1
A discharge valve 198 is provided at the bottom discharge port of 80, and the discharge port is connected to a discharge pipe 197.

Further, although a mechanism for adjusting the height of water supplied by the water supply pipe 190 by moving the siphon pipe 192 in the vertical direction is provided, this mechanism is omitted in the figure.

In the rice washing supply device configured as described above, during rice washing, the rice and water pushed up in the circulation pipe 181 by the drive of the rice washing screw 184 are discharged from the upper end discharge port of the pipe 181 onto the cylindrical net 186. To be done. At this time, the cylindrical net 186
Is rotating counterclockwise, so the rice and water are pipe 18
7 is flowed down and returned to the inside of the rice washing tank 180, where the rice is washed.

Next, when washing the rice and removing the rice into the pot a,
Since the rotation direction of the cylindrical net 186 is clockwise, the pipe 1
Only the rice discharged from the upper end discharge port of 81 is discharged into the pot a, and the water flows down into the rice washing tank 180 through the pipe 187.

By the way, when the rice is taken out into the pot a, water is discharged from the outlet 189 of the water supply pipe, so that the rice on the cylindrical net 186 is flushed with fresh water to feed the pot a at the same time.

On the other hand, since the height of the water to be poured into the pot a is known in advance, the water supply pipe 160 is lowered into the pot a so that the water supply port of the water supply pipe 160 is aligned with the height position and the suction fan is 194 operates, and pressure sensor 195 detects pressure.

As a result, the water supplied from the outlet 189 to the pot a does not overflow and the water absorption pipe 160 and the siphon pipe 1
It is discharged by a siphon formed from 92 and the water level is adjusted. When the pressure sensor 195 detects that the internal pressure of the pipe has changed from the negative pressure to the atmospheric pressure after the extraction of a predetermined amount of rice from the pot a is completed, the height adjustment of the water is also completed at the same time.

In addition, while discharging the water in the pot a with the siphon pipe 192,
As shown in Fig. 20, the negative pressure level in the pipe is
However, h2 + hm is sufficient.

Next, regarding another embodiment of the stand-alone rice washing supply device,
It will be described with reference to FIG.

This device replaces the cylindrical net 186 of the device shown in FIG. 19 with a belt conveyor 200 and configures a mechanism for absorbing water into the pot a and adjusting the water level in the pot a as shown. is there.

That is, the upper end discharge part of the circulation pipe 181 is formed of a porous body such as a net, and a belt conveyor 200 capable of forward and reverse rotation is arranged at the discharge port in an inclined shape so that the rice discharge path 188 side is slightly higher. Make sure that the rice and water can be separated when taking it out of the machine as described below.

Further, in the figure, 201 is a siphon pipe for discharging the water in the pot a by the principle of siphon, and a net 191 is provided at its water inlet.

202 is a water supply pipe for supplying water into the pot a. Both pipes 201 and 202 are allowed to move up and down integrally.

The siphon pipe 201 and the negative pressure generation pipe 203 are connected by a negative pressure connection hose 204 as illustrated. Further, the water supply pipe 202 is connected to the pipe 207 via a water supply hose 205 and a solenoid valve 206. Further, the pipe 207 is connected via a solenoid valve 208 to a pipe 209 which is connected to a tap (not shown).

Reference numeral 210 denotes a sealed tank in which the upper end opening of the negative pressure generating pipe 203 and the upper end opening of the pipe 207 are arranged. Further, in the tank 210, a water level sensor 211 for detecting the water level to be filled in the tank, and the tank 2
A pressure sensor 212 for detecting the internal pressure of 10 is provided.

Further, the lower end openings of the siphon pipe 201 and the negative pressure generating pipe 203 are arranged in the siphon receiving tank 213, respectively.

In the rice washing supply device configured as described above, during rice washing, the rice and water pushed up in the circulation pipe 181 by the driving of the rice washing screw 184 are discharged from the upper end discharge port of the pipe 181 onto the belt conveyor 200. It At this time, since the belt conveyor 200 is rotating counterclockwise, rice and water flow down the pipe 187 and are returned into the rice washing tank 180 to wash rice.

Next, when washing the rice and removing the rice into the pot a,
Since the belt conveyor 200 rotates in the clockwise direction,
Only the rice discharged from the upper end discharge port of the pipe 181 is discharged into the pot a, and the water flows down on the belt conveyor 200 and then is collected into the rice washing tank 180 via the pipe 187.

Next, when the solenoid valve 206 is closed and the solenoid valve 208 is opened at the same time,
Water is supplied into the tank 210. At this time, since the water inlet of the siphon pipe 201 is generally higher than the water surface, the internal pressure is the same as the atmospheric pressure.

Next, connect the siphon pipe 201 and the water supply pipe 202 to the 22nd pipe.
As shown in the figure, lower the valve into the shuttle a and
And the solenoid valve 208 is closed at the same time. As a result, the water in the closed tank 210 flows down into the kettle a and tries to become a negative pressure in the tank 210, but if the water inlet of the siphon pipe 201 is higher than the water surface, it remains at atmospheric pressure.

When the water supply to the pot a progresses and the water inlet of the siphon pipe 201 goes below the surface of the water, the tank 210 becomes a negative pressure, the siphon pipe 201 sucks the water in the pot a, and the negative pressure generating pipe 203 receives the siphon. Suck water in tank 213.

When the respective heights reach h3, h3 or more, the water in the pot a flows out. The theoretical maximum negative pressure is up to h1 = h2.

By such an operation, the amount of water in the kettle a can be adjusted, so if the water inlet of the siphon pipe 201 is set at a predetermined water level position in the kettle a, the water in the kettle a can be pulled up to that position. .

When the water level in the pot is not being controlled, the water level sensor 21
1 detects the water level in the tank 210, and when the water level is insufficient, the solenoid valve 208 is opened to supply water.

Next, still another embodiment of the stand-alone rice washing supply device will be described with reference to FIG.

In the figure, reference numeral 215 is a rice washing tank, and a circulation pipe 216 is provided upward from the bottom of the rice washing tank and the pipe 2

The upper end discharge port of the circulation pipe 216 is provided with a switching mesh body 221 capable of switching between a rice washing position (dotted line position shown in the figure) and a discharge position (solid line position shown in the figure), and its discharge side is connected to the discharge path 222. . The discharge path 222 is provided with a water intake port 223 connected to a water supply pipe (not shown).

The switching net 221 is normally pulled to the rice washing position side by being pulled by the spring 224, and the rice washing switch 225 is operated by the operating rod 226.
It is in the ON state. Further, the switching mesh body 221 is in the discharge position as shown when the solenoid 227 is excited as described later, and the discharge switch 228 is turned on by the operating rod 226. Further, as shown in FIG. 24, the switching net body 221 can be positioned from the rice washing position to the discharging position against the spring 224 by the manual operation of the operation lever 229 provided on the operation panel 230.

Inside the rice washing tank 215, a water level sensor 231 for detecting the lower water level of the rice washing tank 215 is provided, and an overflow port 232 connected to a discharge pipe 232 is provided. Also, the rice washing tank 215
A discharge valve 234 is provided at the bottom of the.

Further, on the operation panel 230, as shown in FIG. 24, a power supply pilot lamp 235 for notifying whether power is turned on, a buzzer 236 for notifying an abnormality as described later, and a rice washing time setting device for setting a rice washing time as described later. 237, and start washing rice
A start / stop switch 238 for instructing termination is arranged respectively. The switch 238 can also be used as a lamp 239 for notifying an operating state as described later.

Next, a block diagram of an electric system of the rice washing supply device thus configured will be described with reference to FIG.

In the figure, reference numeral 240 is a logic circuit, which corresponds to each output of the start / stop switch 238 and the water level sensor 231.
Motor 2 to connect to the rice washing motor drive circuit 245 as described below
20 and a lamp 239 connected to the lamp drive circuit 246, respectively.

Reference numerals 241 and 242 are I / O circuits, 243 is a flip-flop circuit, 244 is a delay circuit, 247 is a clock pulse oscillation circuit, and 248 is an AND circuit.

249 is a rice-washing timer circuit. When the rice-washing switch 225 is turned on to start the rice-washing, the rice-washing time setter 237 counts the preset rice-washing time, and when the counting is completed, the logic circuit 250 is notified. Then, the logic circuit 250 excites the solenoid 227 connected to the solenoid drive circuit 251. This rice washing timer circuit 250 has a counter, a D / A converter,
And a comparator. 252 and 253 are I / O circuits, respectively.

A discharging timer circuit 254 counts a preset discharging time when discharging is started by turning on the discharging switch 228, and when the counting ends, the fact is output to the buzzer driving circuit 255 and the buzzer 236 Sound. An I / O circuit 256 is connected to the discharge switch 228.

An abnormality determination circuit 257 detects that both the rice washing switch 225 and the discharge switch 228 are continuously in the OFF state for a predetermined time, and when both are OFF, the buzzer 236 is sounded and the position of the switching mesh body 221 is abnormal. Inform you that Further, 258 is a reset processing circuit which is driven based on the output signal of the discharge timer 254.

Next, an example of the operation of the rice washing supply device configured as described above will be described.

Now, after turning on the power, the start / stop switch 238 is pressed and at the same time rice is put into the rice washing tank 215 which has been filled with rice. At this time, the logic circuit 240 turns the motor 220
Is stopped and the lamp 239 is made to blink.

When the water level sensor 231 detects the lower limit water level in the rice washing tank 215, the logic circuit 240 starts driving the motor 220 and turns on the lamp 239. At this time, since the solenoid 227 is not in the excited state, the switching mesh body 221 is in the rice washing position.

As a result, the rice and water in the rice washing tank 215 are circulated through the circulation pipe 216.
After being sucked up by, the rice is washed down again into the rice-washing tank 215 to be washed.

Thus, during the rice washing operation, the rice washing switch 225 is turned on, and the clock pulses of the clock pulse oscillation circuit 247 are counted by the rice washing timer circuit 249. Then, when the count value coincides with the rice washing time set by the rice washing time setting device 237, the logic circuit 250 excites the solenoid 227.

By this excitation, the switching mesh body 221 is switched to the discharge position shown in the drawing, and the discharge switch 228 is turned on, and in response to this, the discharge timer circuit 254 starts counting. As a result, of the rice sucked up by the circulation pipe 216 and the water, only the rice slides on the switching net body 221 and is discharged to the outside of the machine.

When the count value reaches the predetermined value and the discharge of rice is completed, the reset processing circuit 258 is activated by this completion signal, the excitation of the solenoid 227 is released, and the switching mesh body 221 returns to the rice washing position again.

By the way, when the amount of rice washed in the rice washing tank 215 is small,
When the operation lever 229 is tilted toward the discharging side against the spring 224 during the rice washing, the discharging switch 228 is turned on and the switching net 221 is at the discharging position regardless of the count value of the rice washing timer circuit 249. Here, since the logic circuit 250 excites the solenoid 227, the switching mesh body 221 is maintained at the discharge position.

Further, when the discharge switch 228 is turned on, the discharge timer circuit 254
Starts counting, and when the count reaches a predetermined value and rice discharge is completed, the reset signal count 25
8 works, the excitation of the solenoid 227 is released, and the switching mesh 22
1 returns to the washing position again.

By the way, the rice washing switch 225 and the discharge switch 228 are
It is normal for one of them to be ON, and both
When the OFF state continues for a predetermined time and is abnormal, the abnormality determination circuit 257 outputs a signal indicating that the position of the switching net body 221 is abnormal.

With this signal, the logic circuit 240 stops driving the motor 220 and at the same time blinks the lamp 259, and the buzzer driving circuit 255 sounds the buzzer 236.

Accordingly, when the position of the switching net body 221 is abnormal,
Both the washing and discharging operations can be stopped to prevent malfunction.

Next, still another embodiment of the stand-alone rice washing supply device will be described with reference to FIG.
