Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rice washing and cooking apparatus for washing rice and cooking rice.

[0002]

2. Description of the Related Art In a means for supplying rice and water to an inner pot without a pot lid, it is common to detect the presence or absence of the pot by contact with an arm.

[0003]

However, the deformation of the arm causes an erroneous detection, and therefore, the rice, water, etc. may be discharged from the cleaning means in spite of the presence of the pot lid.

[0004]

SUMMARY OF THE INVENTION The present invention provides a rice washing and cooking device for preventing erroneous discharge from the cleaning means, and has taken the following technical means. That is, the outer pot 1

The rice washing and cooking device is configured to discharge rice and water from the washing means.

[0005]

The rice is washed by the washing means, and a predetermined amount of water is supplied after washing. Rice and water are discharged from the cleaning means only when the weight measured by the scale 5 is larger than the total weight of the outer pot 1 and the pot lid 3 measured in advance and equal to or smaller than the total weight of the outer pot 1 and the inner pot 2. Then, the discharged rice and water are collected in the inner pot 2.

[0006]

[Effect] When the inner pot 2 is covered with the pot lid 3, the trouble of discharging rice and water from the washing means can be prevented.

Reference numeral 48 denotes a funnel installed in the case 11, the lower part of which is tapered, and a vibrator 49 is provided on the outer surface of this tapered portion. Reference numeral 50 is a drive motor for rotating the fixed quantity supply roll 51. Explaining the block circuit of FIG. 9, reference numeral 52 is an arithmetic control unit (hereinafter referred to as CPU) of a microcomputer having a memory in which various data, programs and the like are built in, which performs arithmetic, logical and comparison operations. . The information input to the CPU 52 via the input interface 53 includes signals from various switches provided on the operation panel 13 (for example, device ON information from the main switch, rice cooking amount selection information from the rice cooking amount switch, etc.). ), And weight information from the scale 5 and the like.
Reference numeral 54 is a switch for inputting the weight of the outer hook, 55 is a switch for inputting the empty weight of the inner hook 2, and 56 is a switch for inputting the weight of the hook lid 3. By inputting these information, the outer hook is The CPU 52 calculates and stores the total weight of 1 and the hook lid 3, the total weight of the outer hook 1 and the inner hook, and the total weight of the outer hook 1, the inner hook 2, and the hook lid 3. Further, when the rice cooking amount selection information is input, the CPU 52 calculates the total weight of the outer pot 1, the inner pot 2, the rice and the water for cooking rice.

The information output from the CPU 52 via the output interface 57 includes the drive motor 50, the vibrator 49, the forward / reverse motor 17, and the motor 2.
8, a drive / stop command signal to the fan drive motor 58, an excitation signal to the solenoid valve 45, a display signal to a display tool provided on the operation panel 13, and the like. The drive command signal to the vibrator 49 turns on the main switch (power source "O").
N "), the vibrator 49 is operated for a predetermined time continuously or at fixed time intervals, the vibrator 49 is operated for a predetermined time before the start of weighing, and the vibrator 49 is operated only during weighing. May be

First, the main switch of the operation panel 13 is turned "ON", and the amount of rice cooked, the rice cooking condition, and the information such as each weight by the switches 54, 55, 56 of the outer pot 1, inner pot 2, and pot lid 3 to be used. Enter. Then, the CPU 52 takes in these pieces of information via the input interface 53 and performs processing such as calculation, and outputs a drive command signal to the vibrator 49 via the output interface 57 to operate for a predetermined period of time. Output. Therefore, the vibrator 49
Vibrates the lower end of the funnel 48, so that the rice can smoothly flow and enhance the weighing accuracy.

Further, it is confirmed whether the rice cooker 41 on which the outer pot 1 provided with the inner pot 2 is placed is in a predetermined position. Incidentally, in association with the "ON" of the main switch, the CPU 52 outputs a drive command signal to the fan drive motor 58 via the output interface 57, so that the fan rotates to operate the device of the operation panel 13. The inside of the case 11 being stored is aroused. When the work starting switch is turned "ON", the CPU 52 outputs a drive command signal to the drive motor 50, and in connection with this, the fixed quantity supply roll 51 rotates to change the position every rotation. A fixed amount of rice is supplied to the tank 14. When the number of rotations corresponding to the set amount of rice is reached, the CPU
52 outputs a stop signal to the drive motor 50.

Subsequently, the CPU 52 outputs a forward drive command signal to the forward / reverse rotation motor 17 via the output interface 57, so that the forward / reverse rotation motor is output via the gears 19 and 20.
The rotary shaft 16 to which the rotary power of the rotor 17 is transmitted rotates in the forward direction to rotate the agitator 21 in the same direction. Further, water is supplied to the tank 14 by the water supply means that communicates with the water supply source. Therefore, the rice is agitated by the agitator 21 and foreign matter such as bran and dust attached is separated. And foreign matter is filtered
It enters the jacket 24 through the hole 23 and is then discharged to a predetermined place.

When a predetermined time has elapsed, the CPU 52 outputs a reverse drive command signal to the forward / reverse rotation motor 17 via the output interface 57, so that the rotating shaft 16 reversely rotates and the stirring body 21 reverses. Therefore, the stirring body 21 is reversed to stir and wash rice and water. Thereafter, the stirring body 21 repeats forward and reverse to wash the rice. After the above washing work is completed, the drain hole of the jacket 24 is closed and the tank 14 is closed by the water supply means.
Supply a predetermined amount of water to.

The CPU 52 determines whether or not the washed rice and water for cooking rice should be discharged from the tank 14 (dropping condition).
That is, the CPU 52 takes in the weight currently loaded on the rice cooker 41 via the input interface 53, and this measured weight is larger than the total weight of the outer pot 1 and the pot lid 3, and the outer pot 1
Only when the total weight of the inner pot 2 is less than or equal to the above, it is judged that the dropping is possible. When the CPU 52 determines that the dropping is possible, it outputs a drive command signal to the motor 28 via the output interface 57, so that the motor 28 is driven and the valve shaft 27 is moved downward via the cam mechanism 29. Move to. Then filter-2
Since the lower end of 3 is open, rice and water fall and are collected in the inner pot 2 of the rice cooker 4. Then, the worker pulls the drawer arm 43 to pull the rice cooker 41 from the leg frame 40 and puts the lid 3 on the inner pot 2. Next, the worker pushes the drawer arm 43 to carry the rice cooker 41 to a predetermined position on the leg frame 40 or a dedicated rice cooker place.

Then, the operator turns the ignition switch to "O".
N ", the CPU 52 causes the output interface 57 to
An "open" signal is output to the solenoid valve 45 via the, and the gas is ignited to start the rice cooking operation. After that, when the rice cooking work is completed, the display of the operation panel 13 displays the completion of rice cooking together with other displays.
