いる。 The first step required for the washing water supply function of the hot water washer.
The requirement is that the flow rate of the flushing water jet can be adjusted appropriately, and this is met as described above. The second requirement is that the outflow of washing water is completely blocked when washing is finished. When the operating knob 13 is set to the stop position, the vane pump 9 is stopped and the solenoid valve 8 is closed. Therefore, the siphon effect caused by the head difference between the still water surface 15, which is stopped by the ball tap 14 in the low tank 6, and the nozzle 4 can be blocked, and this requirement is satisfied. The third requirement is to prevent residual water that has been cooled by the nozzle pipe 3 during standby from spouting out at the beginning of cleaning and giving the user a bad feeling. However, when cleaning is stopped, the vane pump 9 is stopped. As the internal pressure of the hot water tank 1 decreases and the vacuum break valve 11 opens, the cleaning water in the nozzle pipe 3 flows down and stops when the water level in the hot water tank 1 reaches the inlet of the nozzle pipe 3. Therefore, since the cleaning water does not remain in the nozzle pipe 3 during standby, this requirement is satisfied. The fourth requirement is that even if air is present on the suction side of the vane pump, pressure feeding of wash water to the hot water tank 1 can be restored. That is, when a hot water washer is newly installed, or when the toilet is used when the city water is cut off and the water level in the low tank 6 is below the filter 7, the air is naturally drawn from the suction pipe 5. Inhale. Even if the water outage is restored and the water level in the low tank 6 is restored, the suction pipe 5 has a standing head that makes a U-turn, so the cleaning water cannot flow down naturally. In this example, by using a self-priming vane pump, even if air is present in the suction pipe 5, this problem is solved by the suction lift of the pump.
本例は上述の如く、洗浄水供給機能上に必要な
基本の４要件を満たしているが、自吸式のベーン

ある。 As mentioned above, this example satisfies the four basic requirements necessary for the washing water supply function, but since a self-priming vane pump is used as a variable speed, the cost is high due to its structure, manufacturing precision control means, etc. This is the difficult point.

口３４に吸込まれる流量はQ3と等しい。 Next, when the operating shaft 35 is turned using the operating knob 37, the pump 21 is rotated by the operating switch that engages the second cam 36, and the on-off valve 29 that engages the first cam 33 opens. Therefore, the flow rate Q1 discharged from the pump 21 is divided into two in the hot water tank 19,
This produces a bypass flow Q 2 passing through the flow control valve 23 and a jet flow Q 3 sent from the hot water outlet 40 to the nozzle (Q 1 =Q 2 +Q 3 ).Therefore, the flow rate sucked from the low tank into the inlet 34 of the on-off valve is Q Equals 3 .
