It relates to a washing water supply device.

As a conventional washing apparatus for a non-electrical water-saving toilet, for example, a patent document (Korean Patent No. 10-1143269) previously filed and registered by the present applicant is known.

14 to 17, the water supply conversion ball tap for a toilet includes a ball tap 300 for opening and closing water supply, a switching valve 100 for converting water supply to the inside or outside of the water tank by receiving water supply from the ball tap 300, And a direction change control device 200 for controlling the operation of the selector valve 100.

The switching valve 100 is formed by connecting the nozzle unit 110, the switching unit 120, and the discharge valve unit 130 to each other.

The nozzle unit 110 is formed with a nozzle 112 on which a ball tap connection port 111 is formed.

The conversion unit 120 is connected to the nozzle 112 and is a conversion ball operating space 125 in which a water tank-side discharge port 122 opened to the top and a throat 127 opened to the side are formed, and a conversion ball operating space (125) With a conversion ball 121 located inside and having a buoyancy force, the conversion ball 121 moves up and down by buoyancy and suction force to open and close the water tank side discharge port 122 or the throat 127. A discharge port cover 123 may be provided above the water tank side discharge port 122, and the discharge port cover 123 is divided into a tank discharge port 1231 and a make-up water connector 1232.

The discharge valve unit 130 includes a flow path 131 connected to the throat 127 of the switching unit 120, an internal discharge port 132 formed in the center of the flow path 131, and an internal discharge port 132 on the internal discharge port 132. ) Consisting of a diaphragm 133 formed in sequence, a fixing plate 134, and an upper cap 136 formed by a pressure chamber 140 between the diaphragm 133, the inlet pin 135, and the diaphragm 133. do.

The direction change control device 200 is rotatably coupled to an upper channel (not shown) installed while surrounding the opening/closing valve 305 of the ball tab 300, and a lower side of the upper channel (not shown). The water tank 220 and the connection link 230 connected to the switching valve opening and closing lever 137 of the switching valve 100 while moving up and down according to the rotation of the water tank 220 and the connection link 230 It consists of an auxiliary unit 240 coupled to move up and down.

The conventional water supply conversion ball tap for toilets has the following problems.

First, as shown in FIG. 17, the jet nozzle washing water is sprayed immediately after the rim washing water comes out. The spraying time interval between the rim washing water and the jet nozzle washing water is about the time when the flush valve is opened, the water tank level lowers and the ball tap is simultaneously lowered and the ball tap is opened, which is about 0.5 to 1 second. About 0.5 seconds is the time that the rim washing water flows down the wall of the washing ball when viewed from the washing ball, so in reality, the washing water on the rim and jet side is sprayed simultaneously.

As the time difference between the rim washing water and the jet nozzle washing water was not sufficiently secured, it was observed that clogging occurs when the amount of dirt is large as the dirt of the washing ball collects toward the discharge channel at one time. In particular, it was found that more clogging occurs in places where a large amount of toilet paper is used (accommodation facilities, public toilets, etc.).

In an electric type such as a bidet-integrated toilet, the rim washing water first comes out and raises the surface of the washing ball by 15~25mm, and after dispersing the internal dirt, the jet nozzle washing water is sprayed to generate a siphon effect and discharge the dirt from the washing ball through the discharge channel. Because of this, it was found that clogging was very small. (In electric direct-water toilets, it is possible to sufficiently secure the time difference between the rim washing water and the jet nozzle washing water through the solenoid valve.)

Second, among the sites where conventional products are installed, there have been buildings operating a heavy water system that reuses the used tap water. In these places, there are cases in which errors in the switching valve occur due to poor quality of the heavy water.

The diaphragm 133 by blocking a gap between the inlet pin 135 of the outlet opening and closing diaphragm 133 and the micro inlet formed by the inlet 1331 and 1341, which is responsible for the switching operation of the switching valve 100. ) Does not work well and the diaphragm 133 does not return, causing a problem of filling only the water tank without washing the jet nozzle.

The jet water supply pipe 620 and the jet nozzle 1381 are connected by a jet connection hose 650.

The flush valve 600 serves to send water in the water tank 500 to the rim channel as rim washing water.

The make-up water supply pipe 610 serves to send the rim wash supplementary water (⑤) to the rim water channel to supplement the rim wash.

The operation of the washing water supply system 1'of such a toilet will be described.

First, FIG. 5A is a block diagram showing a standby state where the water stored in the water tank 500 is at a normal water level (WL).

In the standby state of FIG. 5A, the cover of the flush valve 600 is closed, and the fill valve A is in an exponential (direct water not supplied) state.

As shown in Fig. 5B, the washing water supply device 1 in such a standby state is in a state where the buoyancy 3 is raised by buoyancy, and thus the fill valve A is in an exponential state.

In addition, since the conversion water container 37 is in a raised state due to the buoyancy of the lower conversion body 44, the pressing part 35 is also in an elevated state.

The normal water level in the standby state is preferably located near the bottom of the upper switching water tank 43 and the upper end of the small water tank 12 as shown in FIG. 5B.

In addition, the switching ball 121 is blocking the discharge orifice 28 by buoyancy of the normal water level, and the inlet nozzle 16, the jet nozzle discharge nozzle 17 and the branch switching nozzle 23 are in a state in which they communicate with each other.

In the standby state as shown in FIGS. 5A and 5B, pressing the hand lever 700 as shown in FIG. 6A starts rim cleaning.

That is, when the cover of the flush valve 600 is opened and the water stored in the water tank 500 is sprayed and discharged through the rim channel as shown in FIGS. 6A and 6B, the stored water in the water tank 500 is -a1 As the water level goes down, the water level of the washing bowl rises, and at the same time, some of them overflow into the drainage channel.

The water in the small water container 12 is gradually lowered by the -b1 water level as the opening and closing plate 13 for the small water container is finely opened under the pressure of water, and a small amount is drained through the drain hole 15. The fill valve (A) is maintained in an exponential state because it is receiving the buoyancy of the remaining water in the bucket (12).

Even if the rim washing water (㉧) flows into the washing ball, since the fill valve (A) remains in an exponential state, there is a difference in injection time between the end of the rim washing water (㉧) and the start of the jet nozzle washing water (②) described later. do.

The -b1 level is above the -a1 level (see Fig. 6B).

After the rim cleaning as shown in FIGS. 6A and 6B is started, the hand lever 700 is returned as shown in FIGS. 7A and 7B, and the cover of the flush valve 600 gradually descends in the closing direction, so that the rim washing water (㉧) is While the injection is maintained, the jet nozzle washing water (②) is started to be injected from the jet nozzle 1381.

The maintenance of the rim washing water (㉧) continues to be opened due to the buoyancy of the buoyancy space under the cover even when the hand lever 700 is returned, and the weight of the residual water control container 660 starts to descend by pressing the top of the cover.

The continuous spraying of the rim washing water (㉧) further lowers the water level of the water tank 500 to -a2, and as the opening and closing plate 13 for the small water container is gradually opened, the water level in the small water container 12 is lowered to -b2.

When the water level in the small bucket 12 is lowered to -b2, the opening/closing lever 4 is also lowered in the direction ⓐ as the buoy 3 is lowered to open the on/off valve 305 to restore the exponential state of the fill valve (A). The water supply status changes and the external direct water supply (①) starts.

That is, the water supply (①) flows to the inlet nozzle 16 and the branch switching nozzle 18 through the fill valve (A), as shown in FIG. 7B, and then through the jet nozzle discharge nozzle 17 for the jet nozzle. It is divided into jet nozzle washing water (②) sprayed from (1381), and turning water (③) starting to fill the conversion water tank 43 through the branch discharge port 23.

Therefore, as shown in FIG. 7A, the rim washing water (㉧) is further maintained until the cover of the plus valve 600 is closed to further raise the water surface of the washing ball (by 15 to 25 mm), and at the same time, from the jet nozzle 1381 Jet nozzle washing water (②) starts to be sprayed.

As shown in FIG. 8A, the cover of the flush valve 600 is closed and the rim cleaning is terminated, but since the jet nozzle washing water (②) is maintained, the drainage channel of the toilet is full and the dirt of the washing ball is completely removed with a siphon action. Discharge.

At this time, as shown in FIG. 8B, the water level in the water tank 500 is -a3, the water level of the turning water (③) of the conversion water tank 43 gradually rises, and the water level in the small water tank 12 (-b3) Is the position of the remaining amount due to the surface tension, and the fill valve (A) maintains the water passing state.

Then, as shown in FIGS. 9A and 9B, the toilet bowl washing is completed according to the end of the rim washing while the jet nozzle washing water (②) is being sprayed.

That is, most of the dirt from the washing bowl of the toilet is discharged through the drainage channel.

In addition, since the rim washing is finished, the water level of the water tank 500 is located at -a3, and the conversion water tank 43 is filled with the direction change water (③).

As shown in Figs. 9A and 9B, when the turning water (③) is full in the conversion water tank 43, the buoyancy of the lower conversion body 44 and the discharge orifice 28 as shown in Figs. 10A and 10B Overcoming the buoyancy of the conversion ball 121 and the internal pressure of the branch conversion nozzle 18, the conversion water tank 43 descends (ⓑ), and the descending conversion water container 37 is an operation lever part ( 36) is rotated in a counterclockwise direction (ⓒ), and the counterclockwise rotation of the operating lever unit 36 pushes the pressing unit 35 downward in the ⓓ direction.

When the pressing part 35 is lowered, the conversion ball 121 blocking the discharge side orifice 28 as shown in FIG. 10B moves to the jet nozzle part 17 by a pressure difference while being lowered by a certain amount and blocks it. Accordingly, the flow of the jet nozzle washing water (②) and the turning water (③) is stopped, and the discharge side orifice (28) is opened, and the supply of the tank-side make-up water (④) and the rim side make-up water (⑤) is started.

The tank side make-up water (④) fills the water tank 500 through the water tank outlet (25) and gradually rises to the +a4 level, and the rim side make-up water (⑤) is sent to the rim water through the make-up water outlet (26). Raise the surface of the washing ball.

When the conversion water tank 37 is lowered as shown in FIG. 10B, the opening/closing pin 49 reaches the fixing bracket 50 and rises to open the drain hole 48 to open the water tank 500. ) To drain (⑥).

As shown in FIGS. 11A and 11B, the tank side make-up water (④) and the rim side make-up water (⑤) are continuously supplied, and the water accumulated in the conversion water tank 43 is continuously drained through the drain hole 48 (⑥). ) While decreasing while the water level of the water tank 500 continues to rise (+a5), but the opening and closing plate 13 for the small water tank is closed in the inside of the small water container 12, so that water cannot enter.

Since the water in the conversion bucket 43 is completed and the water level in the water tank 500 becomes the normal water level (WL), and the water in the small bucket 12 is also filled, the conversion tank part 37 as shown in FIGS. 12A and 12B is When the lower switching body 44 rises upward (ⓔ) by the buoyancy of the lower switching body 44, and the operating link 36 rotates in a clockwise direction (ⓕ) and pulls the pressing part 35 upward (ⓖ), the switching ball 121 It rises by buoyancy and blocks the discharge side orifice 28.

As the water surface of the water tank 500 rises, the opening/closing plate 13 for the small water tank is filled with water that has passed through the outer wall of the small water container 12 while the drain hole 15 is blocked by the pressure due to buoyancy and water level difference. Therefore, the buoyancy 3 momentarily rises up due to the buoyancy of the filled water and lifts the on/off lever 4 upwards (ⓗ) to close the on/off valve 305 to block the water supply to the fill valve (A).

When such a fill valve (A) operates in an exponential state from a water passing state, the water surface of the water tank 500 rises. The opening/closing plate 13 for the small water container under the small water container 12 rises with buoyancy and blocks the drainage hole 15. The water surface of the water tank 500 continues to rise, but water cannot enter the inside of the small water tank 12. Bugu (3) also cannot rise. As the water surface of the water tank 500 continues to rise, the water level inside the small water tank 12 rises rapidly beyond the upper end of the small water tank 12. The buoy (3) immediately rises and the fill valve (A) is switched from the water passing state to the still water state, and the water supply stops. At this time, when the buoy (3) is at the locking water level, the buoy (3) is a water level with sufficient surplus buoyancy, so that abnormal phenomena such as vibrations do not occur even after the water pressure increase and water hammer phenomena immediately after the exponent, and the exponential state remains stable. In such a small water container 12 applied structure, the diaphragm operation inlet (not shown) of the on-off valve 305 can have an area 6 times larger than the micro inlet of a conventional pill valve, so that small foreign substances inside heavy water are caught. There is much less risk of malfunction due to prevention.

Filling of the rim side makeup water is completed in the washing bowl of the toilet. That is, FIGS. 12A and 12B are in the standby state as in FIGS. 5A and 5B.

As described above, since the parallax member 5 plays a role of delaying jet injection even when the rim cleaning is started, the rim cleaning water comes out first and raises the surface of the cleaning ball by about 15 to 25 mm, and after distracting the internal dirt, the jet nozzle cleaning water The clogging phenomenon is eliminated by making a difference in time for discharging and discharging the dirt from the washing ball through the discharge channel while being sprayed.

In addition, since the pressing portion 35 is lowered due to the downward movement of the conversion water tank 37 and the rotation of the operation lever 36, the conversion ball 121 is forcibly changed, even if heavy water containing a large amount of foreign matter is used. No clogging.

In particular, since the branch discharge port 23 has a diameter of at least 1.5 mm and is about 10 times larger than the micro inlet for operating the diaphragm of the prior art, there is much less risk of malfunction due to heavy water foreign matter.

The present invention is not limited to the specific preferred embodiments described above, and any person of ordinary skill in the technical field to which the present invention pertains without departing from the gist of the present invention claimed in the claims can implement various modifications. Of course, it is added that such changes will fall within the scope of the claims description.
