Abstract

Disclosed is a forced drain toilet 10 having a rim drain 11, a jet port 12, and a fresh valve 20 and receiving a pressurized washing water from the outside. The toilet of the present invention and the flushing device belonging to the rim drain water supply pipe 13 for supplying some of the washing water to the rim drain 11 and the remaining washing water to the jet port 12, the larger diameter than the rim drain water supply pipe It comprises a jet port water supply pipe 13 having, and a water supply pipe joint 30 for dividing the washing water into the rim drain water supply pipe and the jet port water supply pipe.
When the piston lever 21 of the fresh valve 20 is operated and the pressure water in the pressure chamber 22 is released, the induction cap 31 which is blocking the jet port water supply pipe 14 is raised, and initial water supply is simultaneously made to both water supply pipes. When the water supply pressure and the water supply at the top dead center of the piston lever is maximized, the induction cap blocks the rim drain water supply pipe so that the water supply is maximized toward the jet port 12 and the water supply is minimized toward the rim drain 11. Finally, the induction cap that descends as the piston lever descends blocks the jet port water supply pipe again, so that the water supply to the jet port is the minimum and the water supply to the rim drain is the maximum.
This action is due to the greater lifting force of the piston lever due to the decompression of the pressure chamber than the resistance (according to the discharge water pressure of the washing water) acting on the connecting member and the induction cap interlocked with the piston lever of the fresh valve. Due to the peculiar configuration of the present invention, the direct water supply pressure in the building during the total flushing process of the toilet can act on the jet port at the maximum, and effectively push out the dirt with a small amount of water in the shortest and fastest time, and then the direct supply pressure decreases. By reducing the jet water supply and increasing the water supply to the rim drain, the inside of the toilet is cleaned and filled with enough water.
According to the present invention, it is possible to effectively divide the high-pressure direct wash water supplied by the pipe network in the building by simply operating the washing button without any electronic device or a separate driving device, and to supply and cut water in sequence, even though it is the water supply. In addition to the effective cleaning of the inner surface of the toilet at the same time as it removes dirt, it is possible to fill a sufficient amount of water in the inner container of the toilet after cleaning, thereby obtaining a feeling of washing and a quality of use almost close to the natural drainage by the water tank.

Description

Forced drain type toilet and its flushing device {Forced drain type toilet and the toilet's water flusher}

The present invention relates to a toilet flushing device having a plurality of feed pipe coupling configurations of which a flow rate is adjusted in a forced drain toilet using water pressure inside the pipe and a water supply pipe joint for supplying washing water to each water supply pipe effectively.

The flushing method of the flush toilet is a natural drainage method in which water is stored in a water tank in advance and the cap is opened with a washing knob to remove stored water and the dirt is removed. It can be divided into the forced drainage washing method to open the flushing valve and remove the dirt by draining the water by the water pressure of the pipe.

Among them, the natural drainage using water tank is widely used as a household toilet because of its low operating water pressure and good operation feeling of washing handle and low drainage noise.However, the water tank increases the volume of the whole toilet and uses low pressure water. The disadvantage is that a large amount of washing water is required in the extrusion process.

The forced drainage type that directly connects the toilet to the building's pipe network has a small volume because the storage tank is omitted, and the strong and short spraying with high pressure water can reduce the consumption of the washing water. However, the high-pressure wash water used at this time has a problem in that drainage noise is large and splashing water splashes during operation, and as the total amount of washing water is reduced, there is a disadvantage in that the entire washing inside the toilet is inferior to dirt discharge.

The forced drainage toilet solves this by placing a fresh valve as a device for discharging water for a certain period of time after the operation of the washing handle and automatically shutting off the water supply. Patent Literature 2, Non-Patent Literatures 3 to 6) can be found.

In addition, in the forced drainage toilet, a rim type outlet (hereinafter referred to as a rim drain) located at the top of the toilet and a water jet located at the bottom of the toilet to improve the cleaning feeling of the entire inner surface of the toilet. jet) Dividing into a jet port (hereinafter referred to as a jet port) effectively removes dirt and cleans the inside of the toilet in an appropriate amount. The cleaning structure according to the divided water supply is found in the prior art document (Patent Document 1) described below. Can be.

Document 6: Registered Utility Model Publication No. 20-0310516 A fresh valve for controlling the operation of the washing handle by air resistance.

Forced drainage toilets are widely used in public toilets because they have little damage and save installation space and water consumption. However, they are still insufficient for domestic toilets and high-grade toilets.

Among them, there is a lack of function to clean the inner surface of the toilet (inner container surface) because the inlet is expanded due to the nature of forced drainage using a small amount of high pressure water. This is because it is difficult to remove and therefore most of the wash water must be fed to the jets.

This is the biggest factor that deteriorates the use quality and cleaning feeling of the forced drainage toilet, compared to the water tank type toilet of the natural drainage type, which performs both the drainage and the inner surface of the toilet using only the water drained from the rim drain. In order to overcome this, allocating a lot of rinsing water to the rim outlet will result in a loss of the unique drainage (water-saving performance), since the total amount of water, including dirt removal, cannot be reduced.

Therefore, in order to apply a forced drainage device without degrading the feeling of washing or the quality of use in household toilets or low-noise luxury toilets filled with water in the inner container, proper washing water allocation between the rim drain and the jet port is required. Important, especially after the effective discharge of dirt by the water jet in the lower part of the toilet within a short time, sufficient amount of water should flow slowly from the rim drain in the upper part of the toilet and evenly clean the inside of the toilet. It is important to adequately fill the toilet with sufficient water.

Looking at the fresh valves described in the prior art document to control the opening and closing time of the valve by using a valve handle delay operation configuration using an optical sensor, a load sensor or air in order to increase or reduce the amount of washing or washing time. However, they are all merely configurations that control the overall wash water volume and do not provide any technical motifs for the wash water quotas or the order of allocation of the rim drain and jet holes.

The present invention to solve the above technical problem,

(A) First, the wash water connected to the pipe network inside the building (also referred to as direct water as a concept distinct from the indirect water stored in the tank) is supplied to the fresh valve 20 directly from the supply pipe, and then operated by the fresh valve. The discharged washing water was properly divided into both the rim drain water supply pipe 13 and the jet water supply water pipe 14, and the average diameter of both water supply pipes was properly adjusted to adjust the total water supply in the range of about 2 to 8 to 4 to 6. .

Next, the water inlet cap 31 was placed inside the water supply pipe joint 30 member so as to sequentially operate the water supply amount at an appropriate time, and the induction cap was configured to interlock with the operation of the fresh valve.

Specifically, (b) When the piston lever 21 of the fresh valve 20 is operated and the pressure water in the pressure chamber 22 is released, the induction cap 31 which blocks the jet port water supply pipe 14 rises, so that both water supply pipes are raised. At the same time the initial watering is done,

(C) When the water supply pressure and the water supply volume at the top dead center of the piston lever is maximized, the induction cap blocks the rim drain water supply pipe so that the water supply is maximized toward the jet port 12 and the water supply is minimized toward the rim drain port 11.

(D) Finally, the induction cap that descends as the piston lever descends again blocks the jet port water supply pipe so that the water supply to the jet port is minimal and the water supply to the rim drain is minimal. Therefore, the direct water supply pressure in the building can act as a maximum on the jet port and effectively push the dirt with a small amount of water in the shortest and quickest time, then reduce the jet water supply and increase the water supply to the rim drain while the direct supply pressure decreases. Cleans and fills the toilet with plenty of water.

According to the flushing device of the present invention, it is possible to effectively divide the high-pressure direct wash water supplied by the pipe network in the building and to supply and cut water sequentially by simple manual operation of the washing button without using any electronic device or a separate driving device. .

Therefore, despite the direct water supply, it is possible to effectively clean the inside of the toilet at the same time as it removes dirt. Moreover, since the inside of the toilet can be filled with sufficient amount of water after washing, the cleaning feeling and quality of use are almost close to the natural drainage by the water tank. You can get it.

In general, the toilet according to the present invention can save the cleanliness and satisfactory toilet feeling, which is the advantage of natural drainage, while maintaining the inherent advantages of forced drainage, such as space saving, water saving, and maintenance convenience. It works.

In order to more specifically represent the main technical features of the present invention will be described in more detail below with reference to an example of the present invention included in the drawings.

However, in the following embodiments (specific example) it is noted that the components expressed in a specific technical term and the structure in which they are combined do not limit the idea inherent in the present invention.

1 to 3 are left cross-sectional views taken along the center line (BB ′ line) of the toilet 10 of the present embodiment, and a cross-sectional view of the AA ′ line cutaway to look at the toilet mounting state of the present invention flushing device. It shows a plan perspective view to look at the divided water supply state of the wash water.

Referring to the drawings, the washing water supply pipe 15 connected to the pipe network in the building is connected to the fresh valve 20, the lower portion of the fresh valve divides the flow of the washing water into the jet water supply pipe 14 and the rim drain water supply pipe 13 and the water supply pipe joint ( 30) are combined.

The washing water coming out of the jet port water pipe 14 pushes the dirt of the toilet bowl 16 while shooting water rapidly and strongly to the jet port 12 having a narrow flow section.

The washing water coming out of the rim drain water supply pipe 13 flows out of the rim drain 11 of a large flow cross section and flows slowly and weakly compared to the jet drain water. This water evenly washes the inner surface of the toilet and fills the empty space of the toilet inner container 16 after the washing water discharged through the jet port is drained.

According to the conventional technique of simply dividing the water coming out through the fresh valve 20 into two parts, more water may flow out to the rim drainage port with less total pipeline resistance, which causes the jet pressure of the jet port to be weakened and thus the dirt is discharged. It may not be removed properly.

On the contrary, if too little water is allocated to the rim drain and the irregular water flow wets the inner container surface, the strong jet washing water of the jet port will be completely drained only from the bottom, so that the dirt remains on the container surface inside the toilet bowl or after the toilet. In many cases, the water did not fill properly inside.

In the present invention, first, the average diameter of both water supply pipes is appropriately adjusted for optimal flow distribution between the rim drain 11 and the jet port 12, so that the total amount of water is adjusted in the range of about 2: 8 to 4: 6. To this end, the water supply pipe joint 30 is formed such that the diameter of the water supply outlet 34 at the jet port water supply pipe 14 is 1.25 times to 2 times larger than the diameter of the water supply outlet 33 at the rim drain water supply pipe 13. Or, when designed as a rectangular pipe, the ratio of the cross-sectional area between the rim drain water supply pipe and the jet water supply water pipe was formed in the range of 1: 1.56 to 1: 4.

The ratio of the desired flow rate obtained through the experiment is that the flow rate of about 3 to 7 is distributed between the rim drain and the jet port. The stronger the set pressure, the more water can be distributed closer to 2 to 8 to save water, which is suitable for toilets where toilet clogging is more important than the cleanliness of the container, while the lower the set pressure, 4 The flow is distributed close to 6 to reduce the drainage noise while increasing the total washing water consumption and to push the dirt out with low pressure / high volume of water. It is suitable for household toilets where the satisfaction of use or the inner cleanliness of the container is more important. If the initial set pressures are the same, the difference in cross-sectional area is proportional to the flow rate in a specific function. Specifically, in terms of the pipe resistance, the jet port side has a larger pipe resistance than the rim drainage port, but the jet port has a lower position, so as the water in the inner container 16 is emptied as the washing water is injected, the water pressure difference is increased. Has a flow characteristic that is almost directly proportional to the cross-sectional area.

4 a to d show a detailed step-by-step operating state of the water washing device of the present invention. The flushing device is a device belonging to the toilet of the present invention, and is a concept of an operation module that can be independently applied to other types of toilets, and is basically a fresh valve 20, a water supply joint 30, and a push rod 27. It may be defined as a valve module in which the toilet operation knob is combined, and may be defined as a washing water supply system including water supply pipes 13 and 14 and a direct water supply pipe 15 in a slightly broader sense.

Hereinafter, the washing device of the present invention will be described with reference to the valve module.

4A shows a state in which the flushing device is in operation before or in operation. The operation of the flushing device proceeds from 4a to 4b-4c-4d and back to 4a.

In FIG. 4B, the pressure chamber 22 is opened by the operation of the push rod 27, and the washing water supply valve 26, which is an internal control valve of the fresh valve 20, is moved by the piston lever 21 that moves up and down. ) Rises up. At this time, the pressure chamber 22 is stored in the pressurized state of the wash water is stored in the pressurized state and then the internal pressure is lost as the piston lever 21 is released into the gap created by the inclination, thus the wash water supply chamber 25 The control valve module, including the wash water supply valve, is raised by the pressure from the pressurized wash water. At this time, since a small amount of pressure water is continuously supplied to the orifice-type supply port 23 through the filter 24, the control valve module is lowered again after a predetermined time (a set time required for flushing the toilet). Therefore, the piston lever 21 is also lowered again, the washing water is cut off. For reference, the total pressure quantity of the pressure chamber 22 is determined by the total stroke distance of the control valve module, which can of course be adjusted by turning the adjusting screw on the top of the fresh valve.

In the present invention, the induction cap which is coupled to the connecting member 32 and the connecting member 32 so as to be rotatable to the piston lever 21 and connected to the piston lever movement and the connecting member movement, lifting or rotating movement Characterized in that 31 is designed to be located inside the water supply pipe joint (30).

In FIG. 4B, when the piston lever 21 of the fresh valve 20 is operated and the pressure water in the pressure chamber 22 is released, the induction cap 31 which is blocking the jet port water supply pipe 14 rises, and is simultaneously initialized to both water supply pipes. Watering is done,

When the water supply pressure and the water supply amount at the top dead center of the piston lever in Figure 4c the maximum water supply to the jet port 12, the induction cap is blocked the rim drain water supply pipe so that the water supply amount to the rim drain (11) to the minimum.

In other words, the induction cap 31 is connected to be interlocked with the piston lever 21 by the connecting member 32 bent in a '-' shape during operation of the fresh valve 20, and at the top dead center of the piston lever. The rim drainage water pipe 14 is to be blocked.

Looking at the internal structure of the water supply pipe joint 30 shown in Figure 4c in the process of the guide projection 35 and the guide cap 31 to guide the lifting and rotation of the induction cap 31 to the maximum, that is, the rim drain In order to avoid the resistance of the washing water coming down in the process of blocking the water supply pipe (13) to the maximum, the water supply outlet (33) of the rim drainage water supply pipe (13) is covered to cover the downward hydraulic pressure working area of the induction cap (31) It can be seen that the projection 36 is further formed. Therefore, the cap of the induction cap is prevented from sinking quickly due to the resistance of the washing water, and as a result, the washing water supply valve 26 may be lowered slowly, and the pressure chamber 22 may be filled with pressure water at a normal speed.

This is illustrated more clearly in FIG. 5. Referring to the top projection view of FIG. 5, it can be seen that when the induction cap is fully rotated, the resistance of washing water is hardly received and the pressure water (= Except for the small orifice tube-shaped supply port 23 which fills the washing water, the maximum working area (maximum vertical projection area) of the downward pressure formed in the induction cap 31 during the peristaltic movement with the piston lever 21 is the washing water supply. It can be seen that the pressure is smaller than the maximum working area (maximum vertical projection area) of the upper hydraulic pressure that the pressure chamber 22 of the fresh valve 20 receives. Therefore, the pressure drop and the pressure re-raising action of the pressure chamber 22 according to the operation of the piston lever 21 are normally not affected by the pulling resistance due to the washing water pressure descending during the induction movement of the induction cap 31. Can be done.

4d shows that the control valve module including the piston lever and the washing water supply valve descends again, and the water supply outlet 33 of the rim drainage water supply pipe side is opened again and the induction cap 31 is again discharged from the bottom dead center of the piston lever. The water supply outlet 34 of the water supply pipe 14 is blocked (again FIG. 4A) so that the water supply amount is the minimum toward the jet port and the water supply maximum toward the rim drain port. Looking at the process of Fig. 4a-bcda direct water supply pressure in the building can act as a maximum on the jet port at the time of Figure 4c and effectively push the dirt with a small amount of water in the shortest and quickest time, and then while the direct supply pressure decreases By reducing the water supply and again increasing the water supply to the rim drain (FIG. 4a), the inner surface of the toilet is washed and the water is sufficiently filled in the toilet.

Looking at the specific shape and coupling form of the induction cap 31 and the connecting member 32 which can be seen through Figures 4 and 5, the connection member is bent to close to the induction cap, or the rotation projection of the induction cap is a water supply pipe joint ( 30) It can be seen that a little gap occurs while being inserted into the guide protrusion 35 for induction motion formed on the inner side. Therefore, the induction cap is not designed to completely block the jet inlet or the rim drain. This is because it does not need to be, and only a small amount of leakage can prevent shocking motion and unnecessary water hammer. In addition, considering that the water supply pipe joint 30 is made of an integral casting, the induction cap 31 and the connecting member 32 should be easily inserted into the upper hole of the water supply pipe joint while being coupled to the fresh valve 20 module. It shows the leakage part reflecting this assembly process. Of course, this amount of leakage is insignificant in the overall flow rate change and does not undermine the basic technical intention of sending the sufficient amount of the second washing water to the rim drain after the sequential supply of the present invention, in particular, the washing water supply to the jet port.

While the embodiments of the present invention have been described in detail with reference to the drawings, the technical spirit of the present invention is not limited to the above embodiments.

In other words, those of ordinary skill in the art to which the present invention pertains may utilize the technical spirit contained in the specification and drawings of the present invention, and as necessary, simple modifications and simple changes that are not included in the specification and drawings of the present invention. An extended example may be further implemented, but this is also obviously included in the scope of the technical idea uniquely possessed by the present invention.

The toilet to which the flushing device of the present invention is applied can be a good substitute for most toilets for public toilets that are used in a state in which water is not filled without a rim drainage to prevent clogging due to a water pressure drop of a direct water supply pipe or to consider water conservation. In addition, it is possible to greatly reduce the residual odor and dirt smell inside the toilet can greatly improve the cleanliness of the public toilet.

In addition, as a modified embodiment of the present invention, if the pressure range of the pressure chamber and the water pipe diameter are manufactured in a variable manner, as well as high marketability as an aftermarket toilet or flush valve for water saving in a home house where a certain water pressure is supplied, Since only relatively inexpensive additional parts such as connecting members and induction caps are required, it can be supplied in large quantities inexpensively as a household toilet in a large residential complex constructed through proper initial hydraulic pressure setting, and it increases the practical space of the home toilet. .
