Next, an embodiment in which the present invention is applied to a beverage supply device having a tea dispenser and a water cooler will be described in detail with reference to the drawings. FIG. 1 shows the internal structure of a beverage supply device (fluid supply device) that includes a tea dispenser in the upper stage and a water cooler in the lower stage. Heater 3 is installed in the upper tea dispenser body 1.
A hot water supply tank (first fluid tank) 2 is provided, and a hot water supply pipe and a tea supply pipe extend from the bottom of the tank 2, and a hot water supply valve 4 and a hot water supply valve 4 are connected to these pipes, respectively. 5 is attached. The pipe for hot water supply ends above the outlet 8, while the pipe for tea supply ends above the tea strainer 6 attached below this pipe. A funnel part 30 is provided below the tea strainer 6 to receive the hot water that has passed through the tea strainer, and the lower end of the funnel part 30 and the hot water supply pipe are disposed close to each other. In addition, the upper tea dispenser has an electric transmission box 21 that stores electrical parts at the outlet 8.
The transmission box 21 houses a drain switch 22 and the like that enable draining from the cold water tank (second fluid tank) 10. In addition to the above-mentioned cold water tank 10 for storing cold water, the lower water cooler main body 9 includes a cooler 16 wound around the outer circumference of the cold water tank 10, a compressor 17 for cooling the cooler 16, etc. It is arranged. A float (liquid detection device) 11 is disposed within the cold water tank 10 to detect the liquid level of cold water within the tank. A swingable detection rod 11a is attached to the float 11, and when the float 11 rises, the detection rod 11a moves as shown in FIG.
The tip of the float 11 contacts the full water detection switch 13 and operates the switch to detect full water.
When the detection rod 1 descends, as shown in Figure 3, the detection rod 1
The tip of 1a contacts a lower limit detection switch 12 and operates the switch to detect the lower limit water level. A pipe from a circulation pump (fluid pressure pump) 15 is connected to the bottom of the cold water tank 10, and a cold water supply valve 7 disposed in the upper stage is attached to a pipe line 14 extending upward from the circulation pump 15. There is. The conduit 14 extends adjacent to and below the funnel section 30. A branch pipe 14a branches from the pipe line from the circulation pump 15 to the water supply valve 7, and this branch pipe 1
4a extends to the top inside the cold water tank. The pipe line 14, the water supply valve 7, and the branch pipe 14a constitute the main part of the water supply circuit. In addition, the pipe line 14, the branch pipe 14a,
The cold water tank 10 and the circulation pump 15 constitute a cold water circulation circuit. As shown in FIG. 2, a push button switch 18 for hot water, a push button switch 19 for hot water supply, and a push button switch 20 for cold water are arranged on the front of the tea dispenser. In the electric circuit shown in FIG. 4, the timer TM is connected to the contact O of the lower limit detection switch 12. The contact C-N of the lower limit detection switch 12 is connected in parallel to the normally open contact X2 of the relay X. A contact point C of the lower limit detection switch 12 is connected to the pump motor PM of the circulation pump 15 and one end of the cold water supply valve 7. The other end of the cold water supply valve 7 is connected to a cold water push button switch 20 and a normally open contact X1 of a relay X, which are connected in parallel. A contact M1 of a timer TM is connected to one end of the relay X, and a drain switch 22 in the electrical equipment box 21 is connected to the other end. Relay X and its normally open contact
A release device is configured to forcibly release the cutoff of energization to the circulation pump 15 so that the circulation pump 5 continues to operate. Next, the operation of the beverage dispensing device according to the preferred embodiment of the present invention will be explained. When water above the lower limit water level exists in the cold water tank 10, the contacts C-N of the lower limit detection switch 12 are electrically connected. Therefore, cold water push button switch 2
When the circuit is closed by pressing 0, the cold water supply valve 7 opens and the cold water in the cold water tank 10 flows through the circulation pump 15 and the pipe line 1.
4 to a receiver (not shown) in the outlet 8, and when the switch 20 is released, the cold water discharge stops. Next, a case will be described in which the cold water in the tank 10 is discharged in order to clean the cold water tank 10. When the drain switch 22 provided in the electrical equipment box 21 is operated to close the circuit, the relay X becomes conductive and its normally open contacts X 1 and X 2 are closed. This causes the water supply valve 7 to operate and open, and the cold water in the cold water tank to circulate through the pump 1.
5, the water is discharged to the outlet 8 via the pipe line 14 and the water supply valve 7. In this case, since the discharge port 8 does not have the above-mentioned receiver (not shown), the discharged cold water is drained to the outside via a drain channel or a drain pipe (not shown) in a well-known manner. When the amount of water in the cold water tank 10 gradually decreases to below the lower limit water level, the contact point of the lower limit detection switch 12 is switched from CN to ON, and the timer TM is energized. At this stage, the pump motor PM and the cold water supply valve 7 are still energized, and water is being drained. Here, the timer
The set time until the TM times up is set so that some water (for example, several tens of cc) remains between the cold water tank 10 and the circulation pump 15 at the time of time-up, and the circulation pump 15 does not operate idly. When timer TM becomes conductive and its set time elapses, timer contact M1 opens and relay X demagnetizes.
The normally open contacts X 1 and X 2 open. In this way, the drive of the pump motor PM of the circulation pump 15 is stopped.
The water supply valve 7 is also closed and the drainage work is completed. When the drainage work is completed, the circulation pump 15 is at a lower position than the cold water tank 10, so it can be considered that substantially all of the water in the cold water tank 10 has been drained. Incidentally, during drainage, the drive of the compressor 17 is stopped by another contact point (not shown) of the relay X.

As described above, the fluid supply device of the present invention includes the drain switch 22 and the release devices X, X 2 electrically connected to the drain switch 22 and the circulation pump 15.
The release devices X, X2 are energized when the drain switch 22 is operated and forcibly release the cutoff of the energization to the circulation pump 15, so that the float 11, which is a liquid level detection device, reaches the lower limit of the tank 10. Even if power is cut off to the pump motor PM of the circulation pump 15 when the liquid level is detected, simply operating the drain switch 22 releases the cutoff and restarts the circulation pump 1.
5, it is possible to achieve the effect of allowing a worker to easily carry out drainage work at a suitable height, which is the objective of the present invention, without having to work by bending over.
