Edge up height.Also, when the hydraulic pressure in the first connecting tube 47 is reached more than certain, i.e. more than the contraction of the rubber bag 59 in water tank 57
During power, the rubber bag 59 in water tank 57 starts expansion because of hydraulic pressure.Thereby, it is possible to which water purification is stored in water tank 57.Moreover, water
In the case that pressure of the case 57 in the first connecting tube 47 is low, the air pressure in the convergent force and water tank 57 of rubber bag 59 is utilized
By in the water purification force feed being stored in water tank 57 to the first connecting tube.
As the direction that water tank 57 is connected to the first connecting tube 47, there is the water inlet of water tank 57 as shown in Figure 4 directed downwardly
The direction of the water inlet of direction and as shown in Figure 5 water tank 57 upward.When with the water inlet of water tank 57 upward with the first connecting tube
47 connections, i.e. in the way of water inlet downwardly facing opening to configure water tank 57 when, the airtrapping in water tank 57 is under top, pressure
It will not be also discharged during drop.Thus, with hydraulic pressure increase, inner air shrinks, when hydraulic pressure discharges, inner air expansion and to the
One connecting tube inner water-supply, therefore rubber bag 59 can not be also set in water tank 57.In addition, in present embodiment, water tank 57 is connected
The first connecting tube 47 is connected to, but also water tank 57 can be connected directly to top cover 101.

It is preferably that the capacity of water tank 57 is set to 800cc~1200cc in the case where the backwater capacity of prefilter 39 is 400cc.
Next, the effect to the water cleaning systems of embodiments of the present invention is illustrated.
The effect under state that discharged water to the water purification that water purification is released from Special water tap 5 is described in detail.From Special water tap 5
Water purification dewatering outlet 21 release water purification in the case of, user operates driving lever to water purification position.By the operation, make movable plate 27
Rotation, and be set to the closing of movable plate 27 draining dewatering outlet 23 and make the first hole 33, the second hole 35, the 3rd hole 37, movable hole 31 with
And the state of water purification dewatering outlet opening.Thus, the raw water for flowing into water cleaning systems 1 from raw water entrance 13 is flowed by the first raw water tubes 7
Flowed into Special water tap 5, and by the first hole 33 in Special water tap 5, and the second raw water tubes 9 flow to by the second hole 35,
And it flow to purifier 3 by the second raw water tubes 9.Also, the raw water flowing in purifier 3 is by the prefilter of purifier 3
39 are purified.Also, by prefilter 39 purify after water flow to the first connecting tube 47.Water purification in first connecting tube 47 is gradually
Flow into adsorption filter 41, but amount of the amount more than inflow adsorption filter 41 of the water purification flowed out from prefilter 39.Therefore,
Hydraulic pressure in one connecting tube 47 gradually rises.Also, when the hydraulic pressure in the first connecting tube 47 reaches certain above, the first connection
Water purification in pipe 47 overcomes the convergent force of rubber bag 59 and the air pressure in water tank 57 and expands rubber bag 59, and is stored in water
In case 57.
On the other hand, the water purification of adsorption filter 41 is flowed into after being purified by absorption filter cylinder 51, flow to the second connecting tube 53.
