Abstract

The invention provides a flush tank device with a flush mode switchover cup, in which flush water is appropriately saved by making the amount of the flush water controllable according to conditions of an installation site. The flush tank device has a ball tap, a float valve (32) and the flush mode switchover cup (46) for switching between large wash and small wash, and a switchover valve (68). In the small wash, the flush mode switchover cup (46) functions as a weight applied to a float valve body (34) of the float valve and quickly causes the valve body (34) to be seated at a valve closure position, thereby limiting the discharge amount of the flush water to a low level. On the other hand, in the large wash, the flush mode switchover cup (46) slowly closes the float valve body (34) by opening a drain hole, thereby allowing a large amount of flush water for the large wash to be discharged. The flush mode switchover cup (46) has a lower cup (52) and an upper cup (54), and the upper cup (54) is formed detachable from the lower cup (52). When the upper cup (54) is fitted to the lower cup, the upper cup (54) can function as the flush mode switchover cup.

The action of present embodiment is described below with reference to Fig. 9 to Figure 12.

Action when Fig. 9 and Figure 10 are illustrated in the flushing stool, the state when defecating flushing operation is rotated in Fig. 9 (I) expression flushing handle 40 depths in Fig. 3.

The transfer valve 68 of this moment is clockwise direction rotation in the drawings because chain 44 is pulled to depths (rear), and the drain hole 62 of the drain hole 58 of following cup 52 and last cup 54 all is in open state respectively.

Then under this state, float-controlled valve valve body 34 and flushing are switched cup 46 and are risen overally by chain 44 tractives, open the outlet opening 38 of Fig. 1.

Just begin to emit the flushing water that is stored in flushed channel 10 inside thus from outlet opening 38.

Be accompanied by and emit flushing water, the water surface W of flushing water descends in the flushed channel 10, and subsequently because water surface W reaches the upper surface of cup 54, when water surface W descended, the water of last cup 54 inside was just discharged from drain hole 62.

But this moment is because the resistance of drain hole 62, makes the decrease speed of the waters surface in the cup 54 waterborne be lower than the decrease speed of water surface W.

As a result, last cup 54 just plays a part weight to float-controlled valve valve body 32.

Thereby do not compare with there being such situation that goes up cup 54, float-controlled valve valve body 32 just begins to descend from earlier stage and causes the amount of having saved flushing water.

When water surface W continue to descend water saving cup 88 when occurring (with reference to Fig. 9 (II) and Figure 10), added the weight effect of the 88 pairs of float-controlled valve valve bodies 34 of water saving cup that have water in inside, add the weight effect that is arranged on the 106 pairs of float-controlled valve valve bodies of water saving ancillary chamber on the cup 54, the continuation that is accompanied by water surface W descends, and cup 46 is switched in flushing and float-controlled valve valve body 34 also all descends.

And at this moment following glass 52 is in the state that is not had by water logging, and float-controlled valve valve body 34 is not played weight.

Following cup 52 switches the cup action as flushing separately and also has the function of water saving, but by on following glass 52, installing cup 54, cup 52 has been lost as flushing switch the function of cup and to the weight effect of float-controlled valve valve body 32, last cup 54 plays a part that flushing is switched glass and to the weight effect of float-controlled valve valve body 32.

After this as shown in Fig. 9 (III), final float-controlled valve valve body 34 drops on the valve seat 36, stops to emit flushing water from outlet opening 38.

In addition, Figure 11, Figure 12 represent to wash the action of handle 40 when the place ahead of Fig. 3 rotating operation is urinated flushing.

Figure 11 (I) expression is with the state of handle 40 when urine is washed the direction rotating operation, the transfer valve 68 of this moment is because chain 44 tractive and be that rotate in the counterclockwise direction at the center with axle 74 forward, makes down glasss 52 drain hole 58 and last glass 54 drain hole 62 be in closed condition.

Float-controlled valve valve body 34 upwards makes outlet opening 38 open because the tractive of chain 44 switches cup 46 with flushing under this state.

Then meanwhile, begin to emit flushing water from outlet opening 38.

Be accompanied by and emit flushing water, as shown in Figure 11 (II) and Figure 12, the water surface W of flushed channel 10 inside descends.

When this urine flushing, the drain hole 62 of going up cup 54 that cup 46 is switched in flushing is in closed condition (following glass 52 drain hole 58 also is in closed condition), last cup 54 is in the state that has water in the internal water retained chamber 60, and float-controlled valve valve body 34 is played a part weight.

Thereby, when flushing urine, when in the flushing water water surface W arrival glass of 54 places, add the weight effect of cup 54 on this, and owing to filled water in the last cup 54, whole heavier than when flushing stool, float-controlled valve valve body 34 switches cup 46 and water saving cup 88 just beginning decline than the stool more Zao stage of flushing with flushing, becomes the valve closing state as shown in Figure 11 (III).

And since this in when urine flushing float-controlled valve valve body 34 shorter from the time that begins to drop to valve-off, the amount of the flushing water of setting during this period of emitting from outlet opening 38 is just few, just can carry out the urine of water closet with a spot of flushing water and wash.

In the superincumbent present embodiment,, will go up cup 54 and be installed in play on the cup 52, and and only wash switching and compare, can save more water by following glass 52 according to on-the-spot differences such as situation are set.

Use different types of cup 54 of going up to regulate water-saving amount at an easy rate.

In addition, under the situation of excessively economizing on water, can take off 54 usefulness of cup and wash switching for following glass 52, just can prevent excessive water saving installing cup 54.

In the present embodiment, the water saving cup 88 of last cup 54 and downside thereof is with respect on following glass 54 position that all is arranged on the sidewall of being partial to groove, disturb mutually with float 28 avoiding, thus, the float 28 that switches cup 46 and float-controlled valve 34 1 liftings or spherical water tap 22 in flushing is accompanied by moving up and down of the water surface and during lifting, can avoid go up cup 54 and water saving cup 88 that cup 46 is switched in this flushing to disturb mutually well, emitting of flushing water moved and not have obstacle ground to carry out smoothly to the action of flushed channel 10 private water supplies with float 28.

And flushed channel 10 does not have can not have under the situation more than needed obstacle ground suitably to use yet in very compact, inner space.

Because the outside around last cup 54 cell walls, be provided with towards the outstanding rib shape rail plate 108 that is longitudinal extension of cell wall inner surface, and because last cup 54 is arranged on the direction of deflection cell wall, therefore when flushing switching cup 46 moves up and down, even last cup 54 and cell wall contact, this rail plate 108 also can partly contact with cell wall, can prevent cup 54 peripheral walls outside, more specifically say in the whole forward outer surface of cell wall direction peripheral wall to contact, can guarantee to go up cup 54 i.e. flushing switching cup 46 stable action with cell wall.

Have again,, be used for switching the flushing switching mechanism simplification that stool flushing and urine are washed so can make because the following valve body 80 and the upper valve body 86 of following glass 52 drain hole 58 of switch and last cup 54 drain holes 62 be arranged on the same transfer valve 68.

In the present embodiment, be provided with by going up cup 54 deflections, disposed demountable water saving cup 88 in the middle of the space that under it, forms, under the state that has water at ordinary times, float-controlled valve valve body 34 is played a part weight, so no matter in the stool flushing still during the urine flushing, because the effect of water saving cup 88, all can make the time of float-controlled valve valve body 34 before closing shorter, can save more flushing water.

Water saving cup 88 is made dismountable, can select to load onto the water saving cup of pre-prepd suitable capacity, just can regulate water-saving amount at an easy rate according to field conditions etc. is set.

Under the situation of excessively economizing on water, can take off water saving cup 88 and avoid excessive water saving in that water saving cup 88 is installed.

In addition, in the present embodiment, owing to be provided with water saving ancillary chamber 106 in last cup 54, under the state of water float-controlled valve 32 is played a part weight at ordinary times, the cup 88 of no matter whether economizing on water can be accomplished water saving.

Under the situation that water saving cup 88 is housed, and at the water saving cup that the capacity maximum of preparing has been installed as this water saving cup 88 o'clock, even under the not enough situation of water saving, also can try hard to realize the water saving of purpose amount.

Figure 13 represents another embodiment of cup 54.

Wherein the example of (1) is the example of not establishing under above-mentioned ledge 102 and water saving ancillary chamber 106 situations; (2) example is to be provided with ledge 102, is etched in the inside of this ledge 102 and goes up example under the situation of not establishing dividing plate 104 between the hydropexis chamber 60 of cup 54 inside; In the case, also become hydropexis chamber 60 in the inside of ledge 102.

And the example of (3) is the example that is provided with breach 110 in last cup 54 peripheral wall front portions.

Another Figure 14 represents to switch with respect to flushing the kind of the water saving cup 88 of cup 46 dismountings.

The maximum of size up and down of (1) in the middle of this, capacity also are maximum; (2) the minimum of size up and down is so inner capacity is also just minimum; And the height of (3) and capacity all be in (1) and (2) between.

Switch the water saving cup 88 that different capabilities like this is installed on the cup 46 in flushing, just can make weight effect difference float-controlled valve valve body 34.

Below just be described in detail an example of the embodiment of the invention, only otherwise exceed purport of the present invention, in addition the structure of all change forms all is possible.
