Description

A mixed jet thrusting water supplier operated with a ball tap float and a toilet equipped with the same {a combination jet thrusting water supplier which is operated by ball tap float and A toilet which has the rim water supplier}

The present invention relates to a water-saving toilet and a water storage device in which a small water tank is installed or a water storage tank is installed at a position lower than a rim water supply port, and is organically coupled with a ball tap operating float to be installed in a narrow water tank space. It is characterized by the rim feed amount control device of high pressure-low pressure water mixed injection method which is compact and has high operational reliability.

The ball tap device, which opens and closes the high pressure water supply pipe by operating a valve filled with pressure water by the float movement due to the change of the water level in the reservoir tank, has a very clear and intuitive operation principle and almost no malfunction even in repeated use. Therefore, it is still effectively used in the water supply control field of water-saving toilets which are introducing various types of electronic valve control technologies.

On the other hand, it is a technology that consumes washing water as effectively as possible without sacrificing cleaning quality in the water-saving toilet bowl field. There is a water supply to supply the wash water.

The toilet described in U.S. Patent Document (1) published in 1977 is to make a discharge port of filthy fluid on one side of a toilet container in which dirt falls, and to create a washing water inlet on the other side to shoot high pressure water. It introduces a configuration in which the high pressure water of the mixture and the hydrant merges in the middle region between the inlet and the outlet, and consequently becomes a mixed fluid (fluid) having an appropriate flow rate and an appropriate flow rate and exiting toward the outlet.

This applies Bernoulli's principle that the total fluid energy of the inlet and outlet fluids should be constant and solves the shortcomings of the traditional high pressure direct injection water-saving washing system. Specifically, the high-pressure water injected at high speed has a problem that the washing water or the dirt splashes when it collides directly with the stationary heavy dirt, and the fluid energy per unit volume is high, but the total fluid energy is small, so it operates for a short time. There is a weak point that can not easily push big, heavy dirt. The document (1) has solved the weak point of such high-pressure jet washing water and has been steadily applied in various forms.

In the modern water-saving toilet, the above-mentioned mixed flow principle is applied not only to the discharge of dirt fluid but also to the control of the flow pressure of the washing water in the reservoir tank. It is implemented as a mixed jet water supply. (For reference, saving water type rim water supply is important to control the amount of rim water supply that is short and fast. Also, short water supply of excessive high pressure water and long water supply of excessive low pressure water are not good.

Documents (2) to (4) introduced below are good examples. Literature (2) is a method in which a low pressure water in a tank is sucked and joined by turning an impeller with kinetic energy of high pressure water flowing into a tank, and then discharged into medium speed fluid through a mixed flow. It uses a separate miniball float (small ball) as an open / close operation configuration to introduce the technology to stop the mixed rim water supply and refill the high pressure water in the storage tank according to the change in the water level in the tank.

Literature (4) has the same basic principles as Literatures (2) and (3). For the sake of the smooth flow of rim water supply, the top of the rim water supply pipe is raised above the full water level of the reservoir tank and exposed to the air. Vents are provided to prevent shock or excessive water supply due to vacuum pressure formed inside the rim water supply pipe.

(1) United States Patent US 4,052,756 Wet type marine jet toilet (disappear) (2) 20-0403907 Toilet bowl cleaning water supply system (3) Toilet bowl with rim water supply device using Korea Patent 10-0007500 injection pump (4) 20-0447022 Toilet water supply device for Korean registered room

As described above, the configuration of supplying medium pressure and medium speed fluid to the outlet side by injecting high pressure and high speed direct water into the tank storage water is very useful in a situation in which a suitable boosting flow is to be applied to the stationary fluid. Representatively, the low tank type toilet where the reservoir tank is placed lower than the toilet seat surface (level of the water supply pipe), or the water supply is used more than half when washing the dirt, and it is small in order to maintain the minimum cleaning quality. In a water-saving toilet equipped with a water tank only, the mixed spray water supply using Bernoulli's principle is more critical.

However, since the introduced toilets are placed in the use environment where water-saving capacity is very important, it is important to realize rim water supply with proper flow rate and flow rate, but it is very important to reduce unnecessary excessive drainage by supplying only accurate flow rate. A typical obstacle in supplying an accurate flow rate is a temporary excessive water supply problem that is swept away by the vacuum pressure formed inside the water supply line at the end of the water supply.

On the other hand, the pressure valve (or fill valve) of the ball tap to open and close the high-pressure water supply has an operating characteristic that gradually starts to supply water and gradually decreases the water supply, which is not an exception in the ball tap applied to the mixed injection water supply device of the technical field of the present invention. . Therefore, in order to have a desired level of water supply / stage in the process of employing an injection nozzle for directly injecting high pressure water into a rim water supply pipe, the rim water supply pipe is surely desired at a desired time regardless of the injection pressure (or injection amount) of the injection nozzle. It needs to be open and closed.

Similar to the present invention in the prior art document, the technique intended to open and close the rim water supply pipe only according to the level of the water storage tank regardless of whether the injection nozzle is continued or stopped is literature (3). However, in the literature (3), another mini float must be installed in addition to the ball tap float inside the reservoir tank, so when the small tank type toilet is applied, the damage of the storage space is large, and the volume of the added float is too small or If it is light, the buoyancy / gravity is also small, so it is difficult to open and close the rim water supply line while overcoming the rim water pressure. For example, in a stand-alone miniball float that rises and falls along the tank level in a separate exercise space, there may be a fluctuation in the process of directly closing the rim water pipe, and there is a delay in retracting or blocking the guide space again. Can be. In addition, when a separate swinging float is made small and additionally mounted with an opening / closing link, it may be difficult for the added float to reliably overcome the injection pressure of the rim water pipe.

It is an object of the present invention to solve the disadvantage of the prior art that it is difficult to open and close the rim water supply pipe exactly at the desired time due to the limitation of the self-buoyancy / self-gravity of the separate small buoyancy body in the field of mixed injection water supply as described above.

In addition, according to the technical characteristics that the compact configuration is urgently needed, the opening of the rim water supply pipe is required even when applied to a storage tank having various sizes and various water level changing conditions while minimizing the volume of the entire water supply device in the storage tank. This allows for easy and reliable adjustment of time and total rim water supply.

The technical idea of the present invention for solving the above problems is as follows.

First, the rim water supply control plate 40 is introduced to the opening and closing the rim water supply pipe 30 is located in the space where the mixed injection is made, but the rim water supply control plate is made of a material that is relatively heavy compared to the volume or add weight if necessary It was configured in such a way that when opening and closing the opening and closing of the rim water supply pipe, it was less affected by the injection pressure of the high pressure injection nozzle (15). This means that the operation of the rim water supply control plate 40 is not dependent on the opening and closing action by its own buoyancy (first external force) or the opening and closing action by the injection pressure (second external force) of the high-pressure water, and only for the ball tap float 20 Operated only by the pressing force (third external force), it is the basis for opening and closing the rim water supply line at a desired time.

Next, the rim water supply control plate 40 is kinematically interlocked with the float 20 for operating the ball tab 10 to be opened by the buoyancy of the float as the third external force and closed by the gravity of the float. This configuration means that the rim water supply control plate is operated by a ball ball operation float that is much larger and heavier than the small sized float used for conventional rim water supply adjustment, and the third external force is set so that the first and second external forces are ignored. Means that the rim water supply control plate 40 can sufficiently handle the unwanted fluctuations or irregular motion.

In other words, each of the values of the first and second external forces as well as the third external force needs to be sufficiently larger than the combined value, and such a design is realistically the area and specific gravity of the rim water supply control plate 40 and the maximum of the high pressure water. By adjusting the volume and weight of the float 20 relative to the injection pressure. Of course, the volume and weight change of the float 20 provided for the ball tap is extremely wide range and high design freedom compared to the conventional mini-ball float or additional fluctuations in the volume / weight change possible value.

In addition, between the float and the rim water supply control plate (specifically, between the float lever and the opening and closing lever of the rim water supply control plate), a throttle water supply control lever 22 capable of adjusting the gap is provided for the rim water supply point and the rim water supply at various water level conditions. It was easy to adjust the time.

Lastly, apart from the path through which the high pressure water is supplied to the injection nozzle through the pressure valve of the ball tap, a small amount of high pressure water can be directly supplied to the rim water supply pipe during the operation time of the ball tap. A separate supplementary water supply pipe 16 was installed in the supplemental water supply pipe 16 to adjust the quantity of supplemental water introduced into the rim water supply pipe 30 through the supplemental water supply control valve 17. This means that the rim water supply control plate 40 more reliably prevents a sudden closing motion and prevents a bad form of vacuum pressure from the rim water supply pipe 30, so that the rim is directly exposed to the injection path of the high pressure water. It is to further increase the operational reliability of the water supply control plate.

The present invention has a very simple and high operating reliability because the difference between the weight and buoyancy of the rim water supply control plate and the ball tap float is large. This minimizes the number of unpredictable design errors that hinder sophisticated blending (or mixing flow).

In addition, in accordance with the design change of the rim water supply control panel, the rim water supply control panel may be able to withstand the injection pressure of the high pressure water even when the rim water supply control plate is exposed on the tank surface temporarily, and open and close the rim water supply pipe at a desired time. This means that the lowest level of the storage tank can be set lower, and it is possible to mount a more compact storage tank.

In addition, since it does not interfere with the flow of the injection fluid in adding weight to the rim water control plate or adjusting the weight of the float, the shape freedom of each part is high and easy to improve, and the stroke adjustment through the control lever is very intuitive. Subsequently, fine adjustment is easy after installation. Therefore, not only can be mass-produced in one basic type, it can be easily applied to toilets of various forms and various ways, and it has the effect of low failure and easy maintenance.

With reference to the embodiment of the present invention included in the drawings in order to technically support the above-described solution of the present invention will be described in detail.

However, in the following specific embodiments, components including specific terminology and combinations thereof do not limit the technical spirit inherent in the present invention.

1 to 4 illustrate the configuration of each part of the mixed jet water supply apparatus of the present invention.

First, the ball tap 10, which is a configuration for a general main pipe, includes a pressure valve 11 and a ball tap operating arm 12 incorporating a pressure-operated packing, also called a fill valve, and a ball tap through a ball tap operating control lever 21. When the float 20 supporting the operation arm 12 starts to descend, the ball tap operation arm 12 tilts when the ball tap operation arm 12 descends, and the high pressure water is supplied. Of course, when the float is raised, the ball tap operating arm is operated to close the pressure water filling space again. When the high pressure water is supplied from the external water supply by the operation of the ball tap 10, the water supply device supplies the same to the injection nozzle 15 through the high pressure water supply pipe 13. In this process, the high pressure water engine 14 may be provided. . The high pressure water pipe 14 may simply be a pipe joint bent in an L-shape and may be a T-type joint in which jet water is further branched downward. In any manner, supplying an appropriate amount of high pressure water to the injection nozzle 15 is unchanged and may be appropriately modified according to the washing method of the toilet bowl.

On the other hand, the rim water supply pipe 30 for inducing drainage on the rim (Rim) side by raising the washing water mixed and sprayed from the bottom of the water storage tank is disposed in a direction coinciding with the injection nozzle 15 and the injection nozzle ( 15) and are placed away from each other. The space separated between the injection nozzle 15 and the rim water supply pipe 30 (exactly, the end of the rim water supply pipe including the rim water supply pipe extension 31) becomes a mixing flow, that is, an induction space in which the mixing injection is made. (See Figure 4A)

On the other hand, the rim water supply control plate 40 for opening and closing the rim water supply pipe 30 by the opening and closing movement caused by the lifting and lowering operation of the float 20 is also disposed between the injection nozzle 15 and the rim water supply pipe (30). . Float 20, which plays a central role of all opening and closing movements, is added with a ball tap operation control lever 21 for transmitting the lifting operation by its own buoyancy to the ball tap operating arm 12, and the lowering operation by the weight of the rim Control plate operation control lever 22 to be delivered to the control plate 40 is added to control the start and end of the mixing injection operation.

The ball tap operation control lever 21 and the control plate operation control lever 22 are respectively independently positioned to allow the ball tab operation arm 12 and the rim water supply control plate 40 to adjust the spacing of the float ( 20).

According to the configuration as described above, the rim water supply control plate 40 closes the rim water supply pipe 30 by the pressing force from the control plate operating control lever 22 according to the descending motion of the float 20, and the float 20 The rim water supply pipe 30 is opened by its own weight in response to the release of the pressing force according to the upward movement of the.

At this time, as an important design point, the rim water supply control plate 40 is a heavy material such that the opening and closing movement ability by its own weight has a larger value than the opening and closing movement ability by the self-buoyancy and the injection pressure applied from the injection nozzle (15) The float 20 is preferably formed such that the lowering force due to its own weight is greater than the opening and closing ability due to the weight of the rim water supply control plate 40.

Meanwhile, the rim water supply pipe 30 is configured to supply water to the rim at various heights from the closed point by the rim water supply control plate 40 by the configuration of the rim water supply pipe extension tube 31, and the rim water supply pipe 30 and the ball tap The supplementary water supply pipe 16 and the supplementary water control valve 17 are disposed between the 10 so as to supply and regulate the supplementary water on the pipe line of the rim water supply pipe 30.

5 to 7 show the specific operation mechanism of the water supply device for each situation.

5 is the initial state of the float 20, the water level of the reservoir tank is full water level and the rim water supply control plate 40 is completely open. At this time, when the ball tap 10 is operated, a vigorous mixed spray flow occurs as indicated by the red arrow in the figure.

6 is a situation in which the ball tap is opened to drain water from the reservoir tank or the water in the reservoir tank is filled again while the ball tab is closed again. At this time, the float 20 is located in the middle height and the rim water supply control plate 40 is overcoming the radical flow of the surroundings by the injection pressure of the injection nozzle without swinging, and is slowly opened and closed while maintaining the half open state stably. . The figure shows a state in which the lower flow is blocked and the total amount of mixed injection is reduced.

7 is a state in which the float 20 descends to the maximum, the water level of the reservoir tank is the lowest level, and the rim water supply control plate 40 is completely closed. Therefore, the mixed injection flow does not occur, and the high pressure water injected through the injection nozzle 15 may be utilized to rapidly fill the storage tank without wasting the additional rim water.

On the other hand, in the above process can be adjusted to supply the optimum supplementary water supply to the supplementary water control valve 17 to maintain a smooth rim water supply change and to prevent a vacuum shock during the temporary sudden closing movement of the rim water supply control plate 40. The supplementary water control valve 17 is preferably manual and can be adjusted to be slightly open at all times, or can be fully opened or closed in case of failure.

Figure 8 shows the toilet of the present invention equipped with a mixed jet water supply. Referring to the drawings, it can be seen the characteristics of the toilet having a mounting condition that the mixed injection water supply device can most effectively function. Specifically, the water supply device is disposed inside the water storage tank disposed lower than the rim water level , The jet water supply pipe branched from the high-pressure water supply pipe 14 of the water supply device and connected to the sewage pot, and the washing handle for opening the ball tab 10. The water is sent out as it is, the rim water supply pipe can be fed to the mixed jet water of a suitable pressure and a suitable flow rate through the above-described mixed injection water supply device.

Of course, when designing a conventional tank type toilet, the externally supplied water can be designed to be used only to fill the rim water and the reservoir tanks. In this case, it is possible to connect the jet water pipe by making the opening and closing port at the bottom of the reservoir tank. The descending speed of the float 20 is different depending on whether direct water is directly used as jet water supply, and even when the pressurized pressure transmission time is adjusted by using the two control levers 21 and 22, the optimum mixing spray timing is realized. There is no problem.

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 skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims. Expansion examples may be implemented, but this is also expressly included within the scope of the present invention, expressed in the following claims.

The present invention is very useful for a manual water-saving toilet which proceeds by dividing the rim drainage and the jet drainage, as well as a manual water-saving toilet which proceeds only rim drainage.

In addition, the present invention is suitably used to induce the primary mixed discharge of the low pressure water and tank storage water supplied from the outside in the initial stage of the washing water boost water supply step even when applied to the water-saving toilet of the tank storage water boosting discharge method by the motor pump. As a result, it is possible to increase the consumption time of the low amount filled in the reservoir tank. Therefore, it provides an important technical basis for further reducing the capacity of the storage tank in the toilet receiving high pressure as well as in the toilet receiving low pressure.
