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 water supply pipe coupling configurations in which the flow rate is controlled and parallel flush valves for effectively supplying the washing water to each of the water supply pipes in a forced drainage toilet using internal water pressure.

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. It can be found in Non Patent Literature 2-5).

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 1: Japanese Patent Laid-Open No. 10-0670437, a toilet equipped with a rim drain and a jet at the same time as a washing tube.

Document 2: Utility Model Publication No. 20-1996-0010609 A double flash valve with two knobs for controlling the water volume. Document 3: Registered Utility Model Publication No. 20-0180709 Double Flash Valve Operated Separately by Button and Handle Document 4: Registered Utility Model Publication No. 20-0209806 A fresh valve for controlling water with a solenoid drive device. Document 5: Registered Utility Model Publication No. 20-0310516 A fresh valve for controlling the operation of the washing handle by air resistance.

Forced drainage toilet, which is operated by one fresh valve, has the advantage of less damage and saves installation space and water consumption.However, it is difficult to allocate water properly to the rim drain and jet port during the removal of dirt. It is difficult to achieve both effects of washing water savings at the same time.

If the double flush valve configuration of Document 2 is applied to the structure of the toilet bowl of Document 1 in the prior art document, both effects of satisfactory use in feces washing and water saving in urine washing can be achieved.

However, the fresh valve is a component that occupies a significant portion of the toilet manufacturing cost, and if applied to two, the price of the toilet becomes high. Therefore, it is necessary to give an overwhelming feeling of quality and usability at a high price compared to a normal flush valve toilet.

The toilet using two fresh valves can basically perform two kinds of washing water control, so it is natural that the flow control is easy. However, simply adding a handle to each valve imposes an intuitive operation on its own, and the coarseness of the washing water supply pattern that responds immediately to the mishandling of the handle during the toileting process lowers the user's satisfaction. do.

In other words, simply installing two fresh valves to control toilet cleaning in one toilet does not solve the above operational disadvantages, which results in a price more expensive than a single toilet and results in lower satisfaction. Loss of competitiveness leads to a loss of market position.

Therefore, in the toilet using two fresh valves, the rim drain and the jet port are divided into two, spraying the washing water, and after the washing water is supplied to the toilet to fill the appropriate amount of water in the toilet bowl, a simple and intuitive one button The construction of a mechanism that can provide various and optimized washing water supply by operation is a very important factor in securing competitiveness in the product.

Looking at the fresh valves described in the prior art document, in order to increase or decrease the amount of washing or washing time, the opening and closing time is adjusted in one or two valves using two handles, an electronic / air delay operation configuration, and the like. However, they are all possible with the help of a drive or sensor that requires user's intentional and complicated operation or auxiliary power, especially in terms of the use quality of the toilet compared to precise flow control, or in terms of toilet operation that should be intuitive, simple and high-class. Considering this, it is difficult to find a better technical idea compared to the traditional natural drainage toilet.

The present invention to solve the above technical problem,

(A) First, the washing water connected to the pipe network in the building (also called direct water in a concept distinct from the indirect water stored in the tank) is directly supplied to the first fresh valve 20 from the supply pipe, and the washing water is supplied. Receiving the first fresh valve to supply it to the jet port water supply pipe (14) and at the same time to be able to supply some of the washing water to the second fresh valve 40 through the connecting pipe (47).

Next, (b) the second fresh valve 40 receiving a part of the washing water from the first fresh valve 20 supplies the washing water to the rim drain water supply pipe 13, in which the first and second fresh valves It can be operated sequentially from the movement of one push rod (27).

(C) the specific flow rate distribution of the wash water between the first and second fresh valves is linked to the operation of the wash water supply valve in the first fresh valve to operate the interlocking cap 28 to open and close the connection pipe 47 between the valves. This was solved by adjusting the pressure water replenishment time according to the size of the pressure chamber in each fresh valve and the diameter of the pressure water supply port.

The toilet using the (double) fresh valve of the present invention can maximize the direct water supply pressure in the building to the jet port in a single normal operation, and the longer the operation button is pressed, the flushing amount of the jet port is continuously maintained. However, since the amount of washing water on the side of the unnecessary rim drainage can be blocked as much as possible, it can effectively cope with a large amount and a small amount of dirt while ensuring excellent operation feeling and water saving performance at the same time.

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 without any electronic device or a separate driving device, and simply remove the dirt with the minimum amount of washing water required. And the inner container washing process can be performed sequentially.

Also, instead of using two fresh valves and two handles attached to each valve, one handle is used to realize a simple and intuitive operation as if operating a single valve. The operation can concentrate the washing water toward the jet port, so that it can flexibly cope with a large amount and a small amount of dirt. Sufficient washing water can be allocated to the rim drain.

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.

Figure 3 is a plan view from above of the main flushing device of the present invention toilet.
Figure 4 is a cross-sectional view showing the operating state of the first, second fresh valve of the flushing device of the present invention step by step.

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.

Looking at the drawings, the washing water supply pipe 15 connected to the pipe network in the building is connected to the first flash valve 20 and the second flash valve 40 next to the first flash valve 20 is arranged side by side and connected to each other have. The washing water supplied through the washing water supply pipe is mainly discharged to the jet port water supply pipe 14 through the first freshness valve 20, and some of the washing water is passed through the second freshness valve 40 through the connecting pipe to the side rim. It is discharged to the drain water supply pipe 13.

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 first fresh valve 20 into two parts, more water may flow out to the rim drain with less total pipeline resistance, which causes the jet pressure of the jet port to be weakened. Dirt 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 FIG. 4, the flushing device of the present invention, which compensates for these disadvantages, is shown for each operation step. Basically, the flushing device which first allocates a large amount of washing water to the jet port, shuts off the water supply of the jet port at the end of the toilet operation, and allocates an appropriate amount of washing water to the rim drain is basically a first fresh valve 20 and a second fresh flash. A valve 40 is formed between the first freshness valve and the second freshness valve, a connecting pipe 47 for supplying washing water from the first freshness valve to the second freshness valve, and the first freshness valve and the second freshness valve. A push rod 27 disposed through the communication pipe 48 between the fresh valves and capable of operating both the first piston lever 21 of the first fresh valve and the second piston lever 41 of the second fresh valve. ) And the like.

Each of the fresh valves is basically similar to that of a conventional fresh valve, except that the first fresh valve 20 includes a second fresh valve (2) in order to limit the rim drain water supply amount near the maximum operation section (the maximum jet water supply amount). 40 is further included interlocking cap 28 for temporarily opening and closing the connecting pipe 47 for sending the wash water.

The interlocking cap 28 is supported by the lower end of the first washing water supply valve 26 that moves up and down according to the operation of the first piston lever 21, and is formed so that the upper end is caught by the outer case of the first flash valve ( See red cross-section member of FIG. 4). Therefore, when the first wash water supply valve 26 moves up and down in operation, when the first wash water supply valve 26 rises to the uppermost position, the connecting pipe 47 is completely closed (FIG. 4C) and lowered below the interruption. When the connector is completely open structure.

The second fresh valve 40 serves to supply the washing water introduced through the connecting pipe to the rim drain water supply pipe 13, and basically the piston lever 21 of the first fresh valve 20 is operated. It is started by push rod 27.

Referring to FIG. 4, the size of the second fresh valve 40 is smaller than the size of the first fresh valve 20. This is because a small amount of washing water is allocated to the rim drainage port. Accordingly, since the second pressure chamber 42 is formed to have a smaller size than the first pressure chamber 22, the time for which the pressure water of the pressure chamber is released may be slightly short. Alternatively, the time that the pressure water rises again can be set longer. This is possible by setting the diameter of the second pressure water supply port 43 to be much smaller than the diameter of the first pressure water supply port 23 to increase the supply port resistance when refilling the pressure water, and to set the refill time accordingly.

The actual total operating time of the second fresh valve 40 (time during which the second flush water supply valve 46 is rising or falling), which is regarded as the pressure water discharge and replenishment time, is two flashes with one push rod 27. It has a significant meaning in the structure of the present invention in which the valve must be operated and stopped simultaneously. When the push rod 27 is pressed, the first piston lever 21 is first touched, and then the second piston lever 41 is touched. In addition, since the first piston lever is touched again while the push rod is retracted, the operating time of the first piston lever is longer than that of the second piston lever. That is, the pressure water can be drained faster and replenished in the first pressure chamber 22 for a longer time, which means that the jet water supply can last longer than the rim drain water supply. This is not a desirable phenomenon in the present invention. Therefore, the second pressure water supply port 43 must be set so that the pressure water can be replenished as long as possible regardless of the time that the pressure water is released from the second pressure chamber 42, so that the water supply of the rim drain can continue even after the water supply of this jet port is completed. In addition, the process of washing the inside of the toilet and filling an appropriate amount of water into the inner container can be performed smoothly.

On the other hand, in order to properly allocate the amount of wash water in the present invention, the interlocking time of the interlocking cap 28, specifically, the actual opening time of the interlocking cap has another important meaning.

The water supply on the rim drain is important only in the early and late stages of the toilet's operation. The actual drainage of dirt in the toilet is jet water supply, and in the midst of operation of the toilet, water supply needs to be concentrated only toward the jet port. That is, it is necessary to suppress the operation of the second fresh valve. To this end, the interlocking cap 28 is disposed inside the first freshness valve 20 to properly block the washing water supplied through the connecting pipe 47 while operating in conjunction with the vertical movement of the first washing water supply valve 26. to be.

The interlock cap 28 completely closes the connecting pipe 47 at the maximum operating point of the first flash valve (the uppermost point of the first piston lever 21 or the first wash water supply valve 26). If this condition persists for a long time, the second wash water supply chamber 45 of the second fresh valve 40 becomes empty (see FIG. 4C). At this time, even after the push rod 27 is retracted, the pressure fresh water of the second pressure chamber 42 should not be exhausted so that the second fresh valve 40 can maintain a smooth operation (during operation). Putting this together, the pressure water discharge and replenishment time (time of the total concept) of the second fresh valve 40 is equal to or longer than the pressure water discharge and replenishment time of the first freshness valve 20, or the interlocking cap ( It needs to be set to the same or longer time than the interlocking operation time of 28).

4 is a diagram in which the above description is expressed sequentially. Step by step,

4a shows an initial state before the toilet operation (both pressures are filled),

4B is a state in which water supply starts to the jet port immediately after the button is pressed (first pressure water starts to fall out),

4C is a state in which the second fresh valve starts operation but no additional water is supplied to the rim drainage port by the interlocking cap (initial residual amount of water is supplied to the rim drainage port), and a maximum water supply is made toward the jet port.

4D is a state in which the button is retracted and the first piston lever 21 is again touched, and thus a small amount of water is supplied to the jet port, so that the maximum water is supplied to the rim drain. (However, since part of the drainage is started again by the pipe resistance by the interlocking cap 28 and the connecting pipe 47 and the first washing water supply valve, the total water supply is less than the maximum water supply on the jet port side.)

4E is a state in which the water supply for the rim drain is reduced and the water supply for the jet port is restarted again (late button operation).

Figure 4f is the water supply to the rim drainage is decreasing and the water supply to the jet port is completely blocked (internal container water filling timing),

It returns to the initial state of FIG. 4A again.

In this process, if the pipeline resistance of the second pressure water supply port 43 and the stroke length of the interlocking cap 28 are adjusted, the two valves can be organically driven with a time difference by a simple one-time button operation. If you press and hold the button for a long time (the user wants to increase the amount of washing instinctively), the condition of 4c ~ 4d is maintained for a long time, and the amount of water that is concentrated in the jet port is restrained as much as possible. You can strongly push the dirt out.

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.

The present invention has a disadvantage that the manufacturing cost and initial purchase cost of the toilet due to the use of a plurality of fresh valves are somewhat expensive, but has a high water-saving performance, easy operation and a wide range of dirt removal range according to the maintenance cost is reduced, hotels, It can be optimally installed in high-end public toilets such as high-end restaurants.
