水することができない問題があつた。 In a continuous rice cooker that cooks a large amount of rice, a fixed amount of washed rice is automatically supplied into a rice cooking container using a rice washer, and then a fixed amount of water is injected using a metering water injector, and the rice and water are added together. The ivy rice cooking containers are sent one by one to the rice cooker and the rice is cooked. By the way, as a quantitative water injection device used in this kind of continuous rice cooking device, conventionally, as shown in FIG. No. 3 has proposed a water injection device equipped with a solenoid valve 5 that is opened and closed by a timer 4. However, this water injection device
The amount of water injected into the system tank 2 is controlled by flowing the water for the time set by the timer 4. Therefore, if the amount of water supplied to the system tank 2 decreases due to a water outage or a drop in water supply pressure, the solenoid valve is activated for a certain period of time. 5
There was a problem in that it was not possible to pour a certain amount of water into the rice cooking container 1 just by opening it.
そこで、この考案は給水用の水槽に所定量の水

A water tank 10 is installed above the water tank 10 to store water in an amount to be supplied to the rice cooking container 1 at one time, and a gauge tube 11 for detecting the water surface position of the water tank 10 is connected to the side of the water tank 10. The gauge tube 11 is formed of a glass tube with a water level scale so that the amount of water in the water tank 11 can be visually checked accurately by reducing the wavy state of the water surface to be detected. A container 12 is provided. The water surface detector 12 has a known structure that detects the upper limit level L 1 and lower limit level L 2 of the water surface by changes in electrical resistance between three electrodes of different heights.
Energizes when reaching L 1 , then increases to upper limit level L1
Even if the water level falls below the lower limit level, it maintains its energization.
A relay R is provided which de-energizes when the water level drops to L2 . Reference numeral 13 denotes a water supply pipe connected to the bottom of the water tank 10, which is piped to supply water to the rice cooking container 1 located below, and a first solenoid valve 14 is installed in the middle. Reference numeral 15 denotes a water pipe for sending water to the water tank 10, which is connected to the lower part of the water tank 10 in order to minimize undulations on the water surface.The water pipe 15 is provided with a second electromagnetic valve 16. 17 is water surface detector 1
This is a control circuit that controls the opening and closing of the first solenoid valve 14 and the second solenoid valve 16 based on the detection operation of No. 2, and as shown in FIG. It consists of

る。 Next, to explain the operation of the metered water supply device, when the power of the control circuit 17 is turned on while the water tank 10 is empty, the relay R of the water surface detector 12 does not operate and its b contact Rb is in the on state. Therefore, the second electromagnetic valve 16 is energized, performs a valve opening operation, and water is poured into the water tank 10 from the water pipe 15. And aquarium 10
When the water level in the gauge tube 11 rises and reaches the upper limit level L1 , the short electrode of the water surface detector 12 comes into contact with the water surface to detect the rising level, and the relay R is energized. Ru. Then, relay R
Since the b contact b of is turned off, the second solenoid valve 16
is turned off and closed, and water supply from the water pipe 15 is stopped. On the other hand, when the a contact Ra of the relay R is turned on at the same time and the indicator light P indicating the completion of water supply lights up, the push button switch B for water supply is pressed. Then, the first solenoid valve 14 of the water supply pipe 13 is energized and opened, and the auxiliary relay X for water supply is energized and its a contact
Turn on Xa to perform self-holding. First solenoid valve 1
Water is supplied to the rice cooking container 1 through 4. When the water level in the water tank 10 is lowered by the water supply from the water tank 10 and the water level in the gauge tube 11 falls below the lower limit level L2 , the relay R of the water level detector 12 is deenergized and its a contact Ra is turned off. Therefore, the auxiliary relay
By turning on the b contact Rb, the second solenoid valve 1
6 is energized, the valve is opened, water is again started to be fed from the water pipe 15 to the water tank 10, and water continues to be fed until the water level in the water tank 10 reaches a predetermined level. In addition,
The rice cooking container 1 filled with rice and a predetermined amount of water is sent to the next rice cooking furnace, and when the new rice cooking container is brought to the outlet position of the water supply pipe 13, the push button switch B is operated again, and the same fixed amount of water is supplied. It is done repeatedly.

ことができる。 As explained above, according to the quantitative water supply device of this invention, the first relay is activated only when a predetermined amount of water is in the aquarium by the operation of the relay that is energized when the water in the aquarium rises to the rising level. Since water is supplied by opening the solenoid valve, there is no problem of pouring less than the predetermined amount of water into the rice cooking container when water is cut off or the water supply pressure drops, unlike conventional timer-type metered water pouring devices. In addition, the water level can be checked with the gauge tube installed on the side of the aquarium, and the water level inside the aquarium is detected by the water level detector installed here, minimizing the influence of ripples on the water surface of the aquarium and ensuring the correct amount of water. Water can be supplied.
