Description

A water managing system

The present invention relates to a water management system, and more particularly, to allow the pure water to be stably supplied to the handpiece or goggle water supply of the treatment unit chair in a dental hospital, or a part supplied from a draft beer shop or a household water purifier line. The present invention relates to a water management system for stably supplying pure liquid.

Recently, as the quality of life improves, the immunity in the human body is weakened.

If people drink or want to work with water, pure water should be provided. However, after pure water is purified through a water purifier or the like, it moves along a certain pipe or the like until it is actually delivered to a person, which is often contaminated in this process.

For example, TVs and other mass-coms are reporting on the status of bacterial infections, such as dental water and dental care equipment, in accordance with existing cases in developed countries that have long known the seriousness of pathogenic bacteria in dentistry.

In particular, dental water is water that exists in the Dental Unit Water Line, which is used because the heat generated during dental treatment (to remove teeth or remove tartar with a machine) can damage the teeth. It is a coolant which is a coolant, and it is a washing liquid of Debris that is generated at the same time.

Thus, water used in dentistry, unlike drinking water, does not matter even if a small amount of heavy metals, but if there are a lot of bacteria that can become pathogens can cause opportunistic infection.

In particular, the biofilm (BIOFILM) is used as a cooling water passage in the situation where blood vessels are exposed (when scaling, oral surgery or periodontal surgery when the margin to be contaminated with gingival is reduced during prosthetic treatment). If formed, it can be more dangerous.

That's why the American Dental Association (A.D.A.) recommends keeping bacteria at less than 200 CFU / ml per ml of dental water coming from the handpiece or the end of a skeleton. This standard is much stricter than the US Department of Health drinking water standard, 500 CFU / ml.

As such, there are many methods for removing bacteria that are contained in water or are generated secondary.

As an example, briefly introducing the technology of dental-related equipment, the technology of the Republic of Korea Patent Publication No. 10-2006-0049297 provides a device for preserving purified sterilized water to the chair by installing dental water management equipment in the machine room.

The main feature of this invention is to convert raw water into R / O water to make purified water close to ultrapure water, and to supply dental water to chairs by containing silver ions or ozone in water.

The feature of this technology is that it can get powerful bactericidal power and is effective in eradicating bacteria.

According to the patent, the method of incorporating silver ions into water provides a method of generating silver ions by infiltrating silver ceramic balls into water.The surface is coated with silver ions after making ceramic-like materials in the form of balls. This provides a phenomenon in which the surface silver gradually blends into water over time.

In addition, looking at the draft beer manufacturing process, by supplying the CO2 from the CO2 gas cylinder to the draft beer cylinder, the draft beer can be passed through the cooler by the power of the CO2 gas to obtain a draft beer.

At this time, from the draft beer to the extraction coke, including a pipe passing through the cooler is formed as a long pipe, as described above, the biofilm can be propagated on the inner wall. This phenomenon also occurs in the piping of the water purifier in the house.

However, the above-described prior art has the following problems.

In the above-described prior art, the concentration of silver cannot be kept constant in the case of dental water, so that the effect of silver ions cannot be seen when using continuous dental water, and the concentration of silver ions increases when the dental water is not used for a long time. There is a problem that can not be used by patients due to the increase in the concentration of odor or silver ions contained in the ceramic.

In addition, since the device is P.O.E (Point of entry: the device is installed near the enemy), it is located in the machine room or far from the chair. This means that no matter how much the raw water is purified and sterilized, the sterilizing water must reach the chair only through long pipes (10-20 m). Therefore, even if the sterilization is 100% in the central unit, if the sterilization water is stored again in this reservoir because of moving along the long pipe or having another large reservoir at the front of the chair, there is a problem of contamination again.

In addition, as time passes, fine particles are generated second in the long pipe and simultaneously attached to the pipe outer wall to form a biofilm. Piping where biofilm begins to form rapidly causes contamination and cannot be resolved until the tubing is cleaned separately.

This is the same problem that occurs in the pipe in which the draft beer flows and the pipe in which water flows through the water purifier in the house.

Accordingly, an object of the present invention is to solve the problems of the prior art as described above, and to provide a water management system that can provide a user with unpolluted water even if the user is far from purified water.

In addition, another object of the present invention is to provide a water management system that can maintain a clean tube by simply removing the biofilm generated on the inner wall of the flow path from the purified raw water to the user.

According to a feature of the present invention for achieving the object as described above, the inventors water management system, a pipe for guiding the liquid from the raw water to the destination, a supply for storing the chemicals and supplying to the pipe, and in the supply A fluid inlet through which fluid is introduced into the supply unit so that the medicine is discharged into a pipe, and a second outlet through which the drug is introduced into the pipe from the supply unit; And, it may be configured to include a control unit for controlling the inflow of water from the raw water to the pipe, and the liquid flow into the pipe from the supply.

Especially in the case of dental water, the number of bacteria contained in the water is reduced during medical treatment. There is an effect that clean water is supplied to the piece or goggle drinking fountain.

In addition, in the water management system of the present invention, the water flowing in the pipe can be washed from time to time to be able to supply clean water at all times, in the case of dentistry has the effect of increasing the quality of care.

Hereinafter, a preferred embodiment of the water management system according to the present invention will be described in detail with reference to the accompanying drawings.

First, the present inventors water management system, as shown in Figure 3, the filter unit 20 for removing the large foreign matter contained in the raw water (S) and the water passing through the filter unit 20 to the destination The pipe 30 for guiding, the water inlet 10 through which the water of the raw water S flows into the filter unit 20, and the water passing through the filter unit 20 are discharged to the pipe 30. The first outlet 12 to be supplied, the supply part 42 capable of storing the medicine and supplying it to the pipe 30, and the supply part 42 so that the medicine is discharged from the supply part 42 to the pipe 30. A fluid inlet 44 through which fluid flows, a second outlet 46 through which the medicine is discharged from the supply part 42 to the pipe 30, and the filter part 20 in the raw water S. And a controller 60 for controlling the inflow of water into the pipe 30 and the flow of the liquid from the supply part 42 into the pipe 30. Can be configured.

The water flow path may be, for example, a flow path of dental water, a path through which draft beer flows, a supply path of water through a water purifier, and the like. For the convenience of description, the flow path of the dental water will be described as an example. .

As shown in FIG. 1, the water management system is provided with raw water S for supplying water. The raw water (S) is a source for supplying water to the water management system of the present invention, may be generally water.

In addition, the water management system of the present inventors is provided with a water inlet 10 through which the water flows into the water management system of the present inventors, as shown in FIG. 3. Water of the raw water (S) is introduced into the system through the water inlet (10).

A filter unit 20 is provided in a path through which water flows along the water inlet 10. The filter unit 20 serves to purify the water flowing along the water inlet 10.

The filter unit 20 may include a plurality of filters 22 and 24 for purifying the water. Of course, it can also be composed of a single filter. In the present invention, as shown in FIG. 3, the filter unit consisting of two filters is taken as an example.

In addition, the secondary filter 24 serves to filter bacteria, which are relatively small foreign substances, from the water filtered by the primary filter 22. In particular, the secondary filter 24 should be able to preserve the residual chlorine of the water flowing. The second filter 24 may be configured as a pleated filter to perform the function.

The pleated filter has pores of 0.1 to 0.2 micrometers, for example, 'High Performance Absolute Pleated Filter' which is commercially available.

The pleated filter may be replaced with a U / F filter (hollow fiber membrane filter). The U / F filter does not have the exact removal force as the pleated filter, but since the pore size is about 0.02 micro meta, it may have an effect equivalent to that of the pleated filter. The reason why the U / F filter can be replaced by the pleated filter is that the chlorine can pass residual chlorine as in the pleated filter.

In addition, when the pleated filter is used, the flow rate of the water flowing through the water inlet 10 and flowing in the course of passing through the first filter 22 and the second filter 24 is 90% or more of the original water pressure. There is an effect that can be maintained.
