[0003]

[Problems to be Solved by the Invention] However,
Improvements have been made to rice that has been subjected to different treatments (for example, removal of bran and dust), especially unwashed rice, for the convenience of general households or business establishments. Therefore, if any rice is washed and cooked, a rice-washing / cooking device is required for each rice, which causes an increase in workplace and cost.

[0004]

SUMMARY OF THE INVENTION The present invention provides a rice washing and cooking device that can handle any type of rice, and has taken the following technical means. That is, a rice washing and cooking device comprising a rice storage unit, a rice washing unit, and a rice cooking unit, and provided with a selection means capable of selecting normal rice work and non-rice washing work, and
In the case of non-washed rice work, the rotation of the rice-washing blade of the rice-washing section is stopped or the rotation speed is reduced or the rotation speed is set lower than that during normal rice work, and the dipping time, which is the previous step of the rice cooking work, is reduced. The rice washing and cooking device is made longer than that during normal rice operation and has a larger amount of water for cooking rice than during normal rice operation.

[0005]

Operation A predetermined amount of rice is sent from the rice storing section 1 to the rice washing section 2 where it is washed and then cooked in the rice cooking section 3. When the non-washing rice operation is selected by the selecting means, the rotation of the rice-washing blade 4 is stopped, the rotation is reduced, or the rotation speed is decreased in the rice-washing operation in the rice-washing unit 2 as compared with the normal rice-operation. .. Also, the rice cooking work is started with a longer soaking time than during normal rice work. In addition, the rice cooking unit 3 is provided with a larger amount of water for cooking rice than during normal rice work.

[0006]

[Effect] A single device can perform washing and cooking operations of normal rice and non-washed rice. And if you choose non-washed rice work,
Since the impact of stirring by the rice washing blade 4 is small, it is possible to prevent damage to the unwashed rice. Further, by lengthening the dipping time, the non-washed rice can absorb water sufficiently and be cooked into delicious rice. In addition, when rice is cooked, the amount of water supplied can be made larger than that in normal rice, so that the rice can be cooked to fullness.

A cover plate 17 is provided at the upper opening of the rice storage 7, and is formed on an opening / closing door 18 that is vertically rotatable from the front end of the cover plate 17 to the central portion. is doing. The rice washing unit 2 has a cylindrical rice washing cylinder 19 whose upper end is detachably attached to the lower surface of the lower plate 12 and a rotatably provided hollow shaft 20 on the outer peripheral surface of which a rice washing blade 4 and the like are provided.
The rice washing cylinder 19 has a tapered lower portion and an opened lower end, and a net 21 having a large number of drainage holes through which the rice does not pass along the extension of the tapered slope is provided in the lower end portion and the bottom portion is provided. A conical valve 24 that opens and closes a drainage jacket 23 having a rice discharge hole 22 is detachably attached, and an opening / closing shaft 26 that is vertically movable by a forward / reverse rotation motor 25 is installed.

Reference numeral 27 denotes a water supply pipe which communicates with a water source, and which is provided so as to be communicable with the drainage jacket 23 through an electromagnetic valve 28, and which also passes through the lower plate 12 to an upper water supply device 29 of a shower configuration which looks into the rice washing tank 19. It is provided so as to be able to communicate with each other via the solenoid valve 30. The motor 31 rotates the hollow shaft 20 via a transmission mechanism. Reference numeral 32 denotes a guide funnel formed by opening both upper and lower end surfaces in a funnel shape, the upper opening of which is seen through the rice discharging roll 9 and the lower opening of which is the rice washing tank 19.
It is provided so as to face the communication hole 33 provided in the lower plate so as to communicate with the lower plate, and is detachably attached to the lower plate 12.

The rice cooking unit 3 is provided with a pot 34 located below the rice discharging hole 22 and a heating means (gas in the embodiment) 35 for heating the pot 34. Explaining the block circuit of FIG. 2, reference numeral 36 denotes an arithmetic control unit (hereinafter referred to as CPU) of a microcomputer having a memory 37,
Performs arithmetic operations, comparisons, logical operations, etc.

The information input to the CPU 36 through the input interface 38 includes the rice washing information from the rice washing switch 39, the normal rice or non-washed rice operation information from the work changeover switch 40, and the rice storage amount detection sensor 6. Of the rice and the operation information from the operation switch (for example, the amount of cooked rice, cooked rice, hardness adjustment, etc.). Also, CPU3
6 is a command signal output from the output interface 42, a drive signal for a motor (not shown) for driving the discharged rice roll 9, a drive signal for driving the motors 25, 31, and opening / closing the solenoid valves 28, 30. Drive signal for heating, heating means 3
There is a signal for activating 5 (for example, ignition).

When the non-washed rice work is input, the CPU 36 shortens the drive time of the motor 31 as compared with the normal work. In this case, the output of the drive command signal to the motor 31 may be in the "OFF" state, and when the motor 31 is a variable speed motor, it may be configured to rotate at a low speed. Also,
When supplying the cooking water, the "open" time of the solenoid valve 30 is set longer than that during normal rice work. Further, after the rice pot and the cooked water are stored in the pot 34, the start of the output of the ignition command signal of the ignition means 35 is set to be longer than in the ordinary rice.

Next, the operation will be described. First, the opening / closing door 18 is opened to supply a predetermined amount of rice (for example, 60 kg, 30 kg, etc.) to the rice storage 7, and then closed. Next, the normal rice work is selected with the changeover switch 40, and the amount of rice cooked (for example, 5 kg) by the operation switch 41.
After selecting, the rice washing switch 39 and the rice cooking switch 40 are turned on. Then, the CPU 36 drives the motor through the output interface 42 for a predetermined time,
The discharged rice roll 9 also rotates in connection with it to supply rice from the rice storage 7 to the rice washing tank 19 via the guide funnel 32. Then, after a lapse of a predetermined time, the output of the drive signal from the CPU 36 is stopped, so that the rotation of the discharged rice roll 9 is also stopped.

Next, the CPU 36 opens the solenoid valve 30.
Output a signal. Then, the water sent through the water supply pipe 27 is supplied from the upper water supplier 29 into the rice washing tank 19. Further, since the CPU 36 outputs a drive signal to the motor 31, the motor 31 rotates to rotate the hollow shaft 20 and the rice washing blade 4. Therefore, the rice in the rice washing tank is agitated by the rice washing blades 4, while the polluted water enters the drainage jacket 23 from the net 21 and is then drained to the outside.

When a predetermined time has passed (about 5 minutes), the CPU 3
Since the output of the drive signal from 6 is stopped, the rotation of the motor 31 and the rice washing blade 4 is also stopped. Further, since the output of the "open" signal of the solenoid valve 30 from the CPU 36 is stopped, the water supply from the upper water supply body 29 is stopped. Next, the CPU 36 outputs an "open" signal to the electromagnetic valve 28. Then, the water sent through the water supply pipe 27 enters the rice washing tank from the drainage jacket 23 through the net 21, so that the foreign matters mixed in the rice (for example, dust and dust) are water. And then discharged from the overflow port of the rice washing tank 19 to the outside of the rice washing tank. When a predetermined time has elapsed, the CPU 36 stops outputting the electromagnetic valve 28 "open" signal. Then, the CPU 36 outputs a drain valve (not shown) "open" signal of the drainage jacket 23, so that the water in the rice washing tank is drained from the net 21 through the drainage jacket 23 to the outside. After that, the CPU 36 outputs the drain valve “close” signal, closes the drain jacket 23, and then outputs the electromagnetic valve 31 “open” signal. Then, the water for cooking rice (cooking water) is supplied from the upper water supplier 29 into the rice washing tank.
Then, when the CPU 36 determines that the water supply time corresponds to the preset amount of cooked rice, the output of the electromagnetic valve 30 "open" signal is stopped.

Next, when the CPU 36 outputs a drive command signal to the forward / reverse rotation motor 25, the opening / closing shaft 26 moves downward by a predetermined length and stops in relation to this, so that the cooking water and the rice in the rice washing tank are separated from each other. It falls through the drainage hole 22 of the drainage jacket 23 and falls into the pot 34. Then, after a predetermined time, the CPU 36 outputs a reverse drive command signal to the forward / reverse rotation motor 25. Then, the forward / reverse rotation motor 25 reversely rotates to move the opening / closing shaft 26 upward, and stops rotating when the original position is reached.

After the rice stored in the pot 34 is soaked for a predetermined time here (about 20 minutes), the CPU 36 commands the heating means 35 to ignite and starts the rice cooking operation. When the non-washed rice work is selected by the changeover switch 40, the drive command time of the motor 31 output from the CPU 36 is the normal rice work (about 5 minutes).
Shorter (about 2 minutes). Therefore, foreign substances (dust, bran, etc.) mixed in the rice while preventing damage to the rice
Can be discharged to enhance the cleaning effect. Further, when the cooking water is supplied, the CPU 36 sets the output time of the electromagnetic valve 31 “open” signal to be slightly longer than that in the normal US time. Then, since more rice cooking water can be supplied into the rice washing tank than in the normal US time, the CPU 36 outputs the ignition command signal to the heating means 35 later than in the normal US time. Therefore, since the rice can sufficiently absorb water in the rice washing tank 7 and the pot 34, it is possible to cook fluffy and tasty rice. In this embodiment, the rice is soaked in the pot 34, but when it is carried out in the rice washing tank, the output of the drive signal output from the CPU 36 to the forward / reverse rotation motor 25 may be slower than that in normal rice.
