A water drain plug for discharging hot water, 43 shown in FIG. 3, is a water supply hose for supplying cleaning water from the water supply device 7 to the hot water tank 8.
[0020]
Next, the operation and action will be described. During normal operation, as shown in FIGS. 9 and 10, by energizing the coil 20, the diaphragm valve 18 is operated to open the closing portion 15, and through the water supply channel a16. Water supplied from the connection unit 14 is supplied to the vacuum breaker valve unit 12. For this reason, the vacuum breaker valve 25 is pushed up by water pressure to open the water supply channel b23 and close the discharge channel 24, and supply water to the hot water tank 8 via the water pressure adjusting unit 13 and the water supply hose 43 ( (Indicated by solid arrows). In addition, while the vacuum breaker valve 25 opens the water supply passage b23 and closes the discharge passage 24, leakage water (indicated by a one-dot chain line arrow) to the discharge passage 24 is discharged from the discharge passage 24 via the discharge port 26. 12 is discharged outside.
[0021]
On the other hand, when the water pressure in the hot water tank 8 rises and reaches a predetermined water pressure, the water pressure adjustment valve 30 releases the blockage of the water discharge port 28 by the water pressure, and the water pressure is supplied via the water discharge boat 28 as shown in FIG. It is drained out of the adjusting unit 13 (the flow of water is indicated by a solid line arrow).
[0022]
Furthermore, the closing portion 15 is opened due to a failure or the like, and the water supply pipe 16 side, that is, the connection portion 14 is connected in a state where the water supply passage 16 and the water supply passage b23 are in communication with each other due to malfunction of the vacuum breaker valve 25. When the negative pressure is reached, as shown in FIG. 12 and FIG. 13, the negative pressure is simultaneously sucked from the discharge path 24 toward the connecting portion 14 (the flow of the external air is indicated by a wavy arrow), and the nozzle unit 9 prevents sewage from being sucked up.
[0023]
On the other hand, leakage water from the water discharge port 28 and the discharge port 26 is discharged from the discharge hose a33 and the discharge hose b34 to the drainage channel a31 provided on the surface of the hot water tank 8, and the drainage channel b32 provided on the surface of the back plate 10 connected thereto. The hot water washing apparatus 1 is discharged through
[0024]
When the water tap 42 of the hot water tank 8 is removed while the water supply is stopped, the water supply path b23 is opened to the outside air through the discharge path 24, so that the outside air is sucked into the hot water tank 8 and opened and closed. The drainage failure due to the pressure drop inside the secondary side water channel of the part 11 can be suppressed, and the water drainage of the secondary side water channel of the opening / closing part 11 can be easily performed. Furthermore, in the normal water supply stop state, water can be easily drained from the secondary side water channel of the opening / closing part 11. Further, in a normal water supply stop state, the vacuum breaker valve portion 12 is located above the uppermost portion of the hot water tank 8 although it is opened to the outside through the discharge passage 24 on the secondary side of the opening / closing portion 11. Therefore, the warm water does not leak from the warm water tank 8 or the like.
[0025]
(Example 2)
14, FIG. 15 and FIG. 16 are a plan view, a front view and a side country, respectively, showing the water channel configuration of the second embodiment of the present invention. 17 is a front view of the water supply device, FIG. 18 is a plan view of the water supply device, FIG. 19 is a cross-sectional view taken along line AA in FIG. 18, and FIG.
[0026]
The second embodiment is different from the first embodiment in that the water discharge port 28 of the water pressure adjusting unit 13 is opened to the discharge passage 24 of the vacuum breaker valve unit 12 and the leaked water is concentrated at one place.
[0027]
In addition, the thing of the same code | symbol as Example 1 shows the same structure, and abbreviate | omits description.
[0028]
Next, the operation and action of the case where the water pressure inside the hot water tank 8 rises during water supply will be described. By energizing the coil 20, the diaphragm valve 18 is operated to open the closing portion 15, and the water supply channel a16 is connected. Then, the water supplied from the connection part 14 is supplied to the vacuum breaker valve part 12. For this reason, the vacuum breaker valve 25 is pushed up by water pressure to open the water supply channel b23 and close the discharge channel 24, and supply water to the hot water tank 8 via the water pressure adjusting unit 13 and the water supply hose 43 ( (Indicated by solid arrows). In addition, while the vacuum breaker valve 25 opens the water supply passage b23 and closes the discharge passage 24, the leakage water to the discharge passage 24 is discharged from the discharge passage 24 to the outside of the vacuum break valve portion 12 through the discharge port 26. .
[0029]
On the other hand, when the water pressure inside the hot water tank 8 increases and reaches a predetermined water pressure, the water discharge port 28 is closed by the water pressure adjusting valve 30 by the water pressure, as shown in FIGS. Then, the water is drained out of the water pressure adjusting unit 13 (the flow of the waste water is indicated by a one-dot chain line arrow).
And since the front-end | tip of the water discharge port 28 is opening to the discharge channel 24, it can drain to the warm water washing | cleaning apparatus 1 exterior via the discharge channel port 26 and the drainage channel b32.
[0030]
Example 3
21, FIG. 22 and FIG. 23 show a cross section of the main part of a third embodiment of the present invention.
[0031]
The third embodiment is different from the first embodiment in that a backflow prevention valve 44 using a duckbill is provided on the secondary side of the vacuum break valve portion 12.
[0032]
In addition, the thing of the same code | symbol as Example 1 shows the same structure, and abbreviate | omits description.
[0033]
Next, the operation and action will be described. Normally, when washing water is supplied to the hot water tank 8, the water supply channel a16 and the water supply channel b23 are in communication with each other as shown in FIG. The backflow prevention valve 44 is opened and water is supplied to the hot water tank 8 through the water pressure adjusting unit 13 (the flow of the water supply is indicated by a solid arrow). Further, when the closing part 15 of the opening / closing part 11 is closed and the water supply is stopped, the water supply path a16 and the water supply path b23 are closed by the diaphragm valve 18 and the vacuum breaker valve 25, as shown in FIG. The backflow prevention valve 44 is also closed to prevent backflow from the hot water tank 8.
[0034]
On the other hand, when the water drain plug 42 of the hot water tank 8 is removed in a state where the water supply is stopped, the water supply path b23 is opened to the outside air via the discharge path 24 as shown in FIG. Is opened and the outside air is sucked into the hot water tank 8 (the flow of the outside air is indicated by a broken arrow), so that it is possible to suppress a drainage failure due to a pressure drop inside the hot water tank 8. In addition, when the water supply is stopped, the water channel is forcibly blocked by the backflow prevention valve, so that the hot water in the hot water tank 8 is prevented from flowing back and discharged from the discharge channel 24 to the outside.
