[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a washing tank apparatus for washing toilets by discharging washing water stored in a washing tank by opening a float valve.
[0002]
[Prior art]
Conventionally, as shown in FIG. 8, this kind of cleaning tank apparatus has been used.
In the figure, reference numeral 200 denotes a cleaning tank, and a hand-washing basin 202 that also serves as a lid is provided on the upper part thereof. A hand-washing water discharge pipe 204 is provided upright from the hand-washing bowl 202.
Handwash water from the handwash water discharge tube 204 falls into the handwashing basin 202 and then falls into the washing tank 200 through a drain hole at the bottom of the handwashing basin 202.
[0003]
Reference numeral 206 denotes a ball tap disposed inside the cleaning tank 200, which performs water supply and water supply stop in conjunction with the lifting and lowering of the floating ball 208.
That is, when the floating ball 208 is lowered, the valve portion of the ball tap 206 is opened and water is supplied into the cleaning tank 200 through the water discharge pipe 210.
On the other hand, as the water level in the cleaning tank 200 rises, the floating ball 208 rises, and when the water surface becomes full, the valve portion of the ball tap 206 is closed to stop water supply.
[0004]
From this ball tap 206, a water conduit made of a bellows tube extends, and its tip is connected to the hand wash water pipe 204. When water is supplied to the cleaning tank 200, the water tap is also passed through this water conduit to the hand wash water pipe 204. Water supply is performed.
[0005]
A float valve (drainage valve) 214 is provided at the bottom of the cleaning tank 200.
The float valve 214 has a spherical float valve body 216 and a valve seat 218, and the float valve body 216 rotates integrally with a cleaning handle 220 provided on the wall portion 200 </ b> A of the cleaning tank 200. The tip of the L-shaped action lever 222 is connected through a chain 224.
Thus, when the washing handle 220 is rotated, the float valve 214 opens the float valve body 216 from the valve seat 218, and the washing water in the washing tank 200 is directed to the toilet through the discharge port 226. Released.
[0006]
In this example, a washing switching device 228 having a container shape is continuously provided above the float valve body 216 of the float valve 214 in a state where it is moved up and down integrally.
Here, the cleaning switch 228 is for switching between large cleaning and small cleaning, and when the cleaning switch 228 is empty, the cleaning switch 228 does not function as a weight, and therefore the float valve body 216 is not connected to the valve seat 218. It takes a long time to sit down and close the valve part, and during this time, a large amount of washing water is discharged from the discharge port 226 for large washing.
[0007]
On the other hand, in a state where water has accumulated in the washing switch 228, the washing switch 228 acts as a weight for the float valve body 216, and as a result, the float valve body 216 lifted from the valve seat 218 quickly descends and the valve Sit on the seat 218. Therefore, in this case, the discharge amount of the cleaning water is reduced for small cleaning.
[0008]
The cleaning switch 228 is provided with a fitting portion 232, and the fitting portion 232 is fitted on the outer peripheral surface of the overflow pipe 230 so as to be slidable up and down, and the cleaning switch 228 together with the float valve body 216. They are guided up and down by them.
[0009]
In the cleaning tank apparatus shown in FIG. 8, the lifting and lowering movement of the floating ball 208 is transmitted to the valve portion of the ball tap 206 via the interlocking arm 236, and the valve portion is opened and closed.
Thus, the floating ball 208 and the interlocking arm 236 are connected by the bolt 234, and the position of the floating ball 208 can be adjusted up and down by adjusting the screwing amount of the bolt 234 to the floating ball 208. .
Thus, the amount of cleaning water when the cleaning tank 200 is full can be adjusted.
[0010]
Specifically, when the position of the floating ball 208 is moved upward by adjusting the screwing amount of the bolt 234, the valve portion of the ball tap 206 closes slowly when water is supplied into the cleaning tank 200. A lot of water is supplied.
Conversely, when the position of the floating ball 208 is moved downward, the valve portion of the ball tap 206 closes quickly when water is supplied into the cleaning tank 200, and the amount of water supplied into the cleaning tank 200 is adjusted to be small. The
In FIG. 8, W represents the position of the water surface of the cleaning water in the cleaning tank 200.
[0011]
[Problems to be solved by the invention]
In the case of the washing tank apparatus shown in FIG. 8 as described above, the water level W of the washing water at the time of full water can be adjusted up and down by adjusting the position of the floating ball 208 to the upper side or the lower side with the bolt 234.
That is, the amount of water stored in the cleaning tank 200 can be adjusted. For example, when 10 L (liter) of wash water is discharged during large washing, the amount of wash water discharged is adjusted to, for example, 8 L by moving the position of the floating ball 208 downward. Is possible.
[0012]
Similarly, when 8 L of washing water is discharged at the time of large washing, the amount of washing water discharged is adjusted to 6 L by moving the position of the floating ball 208 further downward. Is theoretically possible.
However, when the discharge amount of the wash water is greatly reduced in this way, the position of the water surface W at the time of full water is drastically lowered, and accordingly, the momentum of the water flow when discharging the wash water from the discharge port 226 is increased. It becomes weak.
As a result, the cleaning efficiency at the time of toilet cleaning is lowered, and the toilet cleaning cannot be performed well.
[0013]
[Means for Solving the Problems]
The cleaning tank apparatus of the present invention has been devised to solve such problems.
Thus, in the first aspect of the present invention, (b) a ball tap for supplying and stopping water supply to the cleaning tank based on the lifting and lowering of the floating ball; A washing tank having a valve body and a valve seat, and provided with a float valve as a drain valve that opens when the float valve body floats from the valve seat and discharges the washing water in the washing tank in the device, (a) forms a container shape, has a housing portion for holding while the reservoir of water even during full flushing to increase release the wash water, I weight and Do for the float valve body at the time of the large cleaning, a predetermined amount less regulations basin unit the water release amount of washing water, without Rutotomoni, the (b) container shape provided in a state where and to the float valve body and integrally lift the upper side of the float valve body, small flushing In some cases, water has accumulated inside It becomes a weight for the float valve body, and the float valve body is quickly seated on the valve seat to restrict the amount of water discharged from the washing water to a small amount for small washing, while the float valve body becomes empty during large washing. A state in which a washing switching device for switching between large and small washings that is slowly seated on the valve seat and discharges more washing water than at the time of the small washing is raised and lowered integrally with the float valve body above the float valve body It is provided with the said water reservoir.
[0014]
[Operation and effect of the invention]
As described above, the present invention is in the state of storing water inside the container even during a large cleaning, and thus, a water reservoir that acts as a weight with respect to the float valve body is provided above the float valve body. According to the present invention, the time from when the float valve is opened to when the float valve is closed is reduced according to the present invention. It can be made shorter than that at the time of large washing, whereby the amount of water discharged from the washing water can be restricted by a predetermined amount, and water can be saved during toilet flushing.
[0015]
Moreover, according to the present invention, since the position of the surface of the wash water stored in the wash tank can be prevented from being lowered, the momentum of the water flow when the wash water is discharged can be strongly maintained, and thus the toilet bowl It is possible to maintain a high cleaning efficiency with respect to the toilet bowl and to perform toilet cleaning well.
In addition, in the present invention, the space in the cleaning tank can be reduced, and the cleaning tank can be made compact.
[0016]
In the present invention, in addition to the water reservoir , a cleaning switching device for switching between large cleaning and small cleaning is further provided. In the cleaning tank device of the present invention, the amount of discharged water of cleaning water during the large cleaning is stored in the water reservoir. In addition to being able to be regulated to a predetermined amount less by the action as a weight, the amount of water discharged from the washing water can be controlled to be large or small at the time of large washing and small washing by the action of the washing switch.
[0017]
【Example】
Next, embodiments of the present invention will be described in detail with reference to the drawings.
1 and 2, reference numeral 10 denotes a cleaning tank, which has a double tank structure including a ceramic outer tank 12 and an inner resin tank 14 inside thereof.
A ceramic hand-washing basin 16 that also serves as a lid is provided on the upper part of the outer tank 12, and a hand-washing water discharge pipe 18 is provided upright from the hand-washing basin 16.
A drainage hole 20 is provided at the bottom of the handwashing bowl 16, and the handwash water discharged from the handwash water discharge pipe 18 falls from the drainage hole 20 into the cleaning tank 10.
[0018]
A ball tap 22 is disposed inside the cleaning tank 10.
The ball tap 22 has a valve portion connected to a floating ball 28 via an interlocking arm 24 and an adjusting bolt 26. The valve portion is opened and closed by raising and lowering the floating ball 28, and the cleaning tank is opened and closed by opening and closing the valve portion. Water supply to 10 and water supply stop are performed.
The ball tap 22 is provided with a water discharge port 31 for supplying water to the inside of the cleaning tank 10, and a water conduit 30 comprising a bellows tube for supplying water to the hand washing water discharge pipe 18 from the ball tap 22. It extends, and the front-end | tip part is inserted and connected to the hand-washing water discharge pipe 18.
[0019]
A float valve (drain valve) 32 is disposed at the bottom of the cleaning tank 10.
The float valve 32 has a spherical float valve body 34 and a valve seat 36. When the float valve body 34 floats from the valve seat 36, the discharge port 38 is opened, and the float valve body 34 The discharge port 38 is closed by sitting on the seat 36 (see FIG. 1).
[0020]
On the other hand, a cleaning handle 40 is rotatably attached to the wall of the cleaning tank 10.
An action lever 42 having an L-shape extends from the cleaning handle 40 into the cleaning tank 10, and a tip of the lever 42 and the float valve body 34 are connected via a cleaning switch 46 by a chain 44.
Here, the cleaning switching device 46 and the float valve body 34 are connected so as to move up and down integrally. Further, the cleaning switching device 46 is provided with a cylindrical portion 48, and the cylindrical portion 48 is an overflow pipe. The outer peripheral surface of 50 is externally slidably fitted.
The cleaning switch 46 and the float valve body 34 move up and down under the guidance of the cylindrical portion 48 and the overflow pipe 50.
[0021]
3 to 5 show the configuration of the cleaning switch 46 in detail. As shown in the figure, the cleaning switch 46 is formed with an engagement hole 54. On the other hand, the water reservoir 76, which will be described in detail later, is formed with an engaging claw 53 that protrudes downward, and the cleaning switch 46 and the water reservoir 76 include the engaging hole 54 and the engaging claw. 53 are engaged with each other in a watertight manner in the vertical direction.
[0022]
In this example, the water reservoir 76 has a container shape with an open top, and water is stored in the pair of accommodating portions 78 in both large cleaning and small cleaning. Water is caused to act on the float valve body 34 as a weight.
That is, in this example, as shown in FIGS. 7 (B) and 7 (C), water is accumulated in the accommodating portion 78 of the water reservoir 76 in both the large washing and the small washing, and the float The valve body 34 always acts as a weight.
Moreover, the water reservoir 76 forms the accommodating part 74 which made the lower end open shape.
[0023]
A drain hole 58 is formed in the bottom portion 56 of the cleaning switching device 46 at a position shifted in the radial direction from the center portion. The drain hole 58 is opened and closed by a switching valve 60 for switching between large cleaning and small cleaning. It is like that.
The switching valve 60 has a cylindrical body 62 and a valve shaft 64 inserted therein so as to be slidable up and down, and a valve body 68 is provided at the lower end of the valve shaft 64. The body 68 is biased downward by the spring 69 in FIGS. 4B and 5A.
[0024]
A rotating shaft 70 protrudes horizontally from the cylindrical body 62 of the switching valve 60, and the rotating shaft 70 can rotate in a shaft hole 72 of an upright portion 71 formed so as to protrude upward from the cleaning switch 46. Is fitted.
That is, the entire switching valve 60 can swing around the rotation shaft 70 between a position indicated by a two-dot chain line and a position indicated by a solid line in FIG.
Here, the two-dot chain line in FIG. 5 (A) represents the state during the large cleaning, and the solid line represents the state during the small cleaning.
[0025]
Specifically, during large washing, the chain 44 is pulled in the direction indicated by D in FIG. 5A, and at this time, the switching valve 60 is in a state in which the valve body 68 is disengaged from the drain hole 58 in the left direction in FIG. As a result, the water drain hole 58 is opened, so that the water stored inside the cleaning switch 46, specifically, the water stored inside the storage portion 75 and the storage portion 74 is extracted from the water drain hole 58 to the outside for cleaning. The inside of the accommodating part 75 and the accommodating part 74 in the switch 46 will be empty.
[0026]
On the other hand, at the time of small washing, the chain 44 is pulled up in the direction indicated by S in FIG. At this time, the valve body 68 is slightly lifted to temporarily open the drain hole 58, but when the operating force applied to the cleaning handle 40 is removed, the drain hole 58 is quickly closed by the biasing force of the spring 69.
Therefore, the water stored in the accommodating portions 75 and 74 is not extracted from the drain hole 58 and is held in the accommodating portions 75 and 74 as it is.
[0027]
Thus, when the water drainage hole 58 is opened and the water inside the accommodating portions 75 and 74 is extracted through the drainage hole 58 during the large cleaning, the water inside the accommodating portions 75 and 74 is weighted to the float valve body 34. Therefore, as shown in FIG. 7 (B), the float valve element 34 has a float valve body when the water surface W descends as the washing water is released, compared to the small washing time shown in FIG. 7 (C). The descending start timing of the body 34 is delayed, and the time until the float valve 32 is closed becomes longer.
During this time, a large amount of washing water is discharged from the washing tank 10 and large washing (washing during stool) is performed.
[0028]
On the other hand, in the state where water has accumulated inside the accommodating portions 75 and 74 during small washing, the water inside the accommodating portions 75 and 74 is used as a weight with respect to the float valve body 34 as shown in FIG. Therefore, at the time of small washing, when the position of the water surface W is lowered as the washing water is released, the float valve body 34 starts to descend at an early stage, and the time until the seating on the valve seat 36 is shortened. .
As a result, the amount of water discharged from the cleaning water is restricted at the time of small cleaning.
It can be considered that the storage portion 74 of the water reservoir 76 forms a part of the storage portion of the cleaning switching device 46.
[0029]
FIG. 7A shows the lowering start position of the float valve body 34 when the water reservoir 76 as described above is not provided.
As can be seen from the comparison between FIG. 7A and FIG. 7B, the float valve body 34 can be maintained even during large washing by providing a water reservoir 76 and storing water in the accommodating portion 78. As the water surface W descends, the descent starts from a position relatively lower than that in FIG.
That is, when the water reservoir 76 is provided, the float valve body 34 starts to descend from an early stage and performs the valve closing operation, compared with the case where the water reservoir 76 is not provided.
For this reason, compared with the state of FIG. 7 (A), the discharge amount of the cleaning water amount at the time of large cleaning is regulated so much.
[0030]
In the cleaning tank apparatus of the present example as described above, the time until the float valve element 34 is seated on the valve seat 36 can be shortened by the action as the weight of the water reservoir 76 even during large cleaning, thereby The amount of water discharged from the washing water can be regulated to be a predetermined amount less than that at the time of conventional large washing, and water can be saved during toilet flushing.
In addition, in this example, it is possible to prevent the position of the water surface of the cleaning water in the cleaning tank 10 from being lowered, so that the water force during the toilet cleaning can be strongly maintained, and the cleaning efficiency for the toilet is kept high. The toilet bowl can be washed well.
[0031]
As a means for reducing the discharge amount of the wash water while maintaining a high water level at the time of full water, for example, a means such as putting a filling such as a plastic bottle in the wash tank 10 is conceivable. In this case, A certain amount of space is required, and therefore this means can only be applied to large washing tanks 10 above a certain level.
However, according to this example, the space inside the cleaning tank 10 can be made small, and an advantage that can be applied to the small cleaning tank 10 can be obtained.
[0032]
Further, in this example, since the cleaning switch 46 is further provided in addition to the water reservoir 76, the amount of water discharged from the cleaning water is controlled to be large or small by the action of the cleaning switch 46 at the time of the large cleaning and the small cleaning. be able to.
[0033]
Although the embodiment of the present invention has been described in detail, this is merely an example.
For example, in the above example are installed in the cleaning tank unit by assembling a cleaning switch and separate basin devices, it is also possible, such as integrally constituting the water reservoir unit and the cleaning switch.
Furthermore, the present invention can be configured in various modifications without departing from the gist of the present invention, such as being applicable to various cleaning tank apparatuses other than the above embodiments.
