Description

[Detailed explanation of the invention] (Industrial application field) This invention is a small and inexpensive way to connect a water purifier, which is mainly used for industrial purposes, to a water pipe faucet so that it can be easily used in ordinary households. This invention relates to a home-use water purifier that allows you to obtain highly purified water.

(Prior art) Conventionally, such water purifiers have mainly been used for industrial or medical purposes, and there are only a few water softeners of this type that can be used in ordinary households by connecting to a water pipe faucet. It's nothing more than that.

(Problem to be solved by the invention) By the way, the purpose of the above-mentioned water softener is to obtain delicious drinking water, and for example, it removes magnesium and calcium from tap water, but it removes cations and anions. Ions cannot be removed,
Therefore, pure water (distilled water) cannot be obtained. However, even in ordinary households, there are frequent cases when pure water is needed, such as when using an iron, a humidifier, or when cleaning contact lenses.As mentioned above, there are suitable water purifiers that can be used at home. Since there is no water available, we have no choice but to use tap water as is, and when it is absolutely necessary, we purchase commercially available distilled water. This has led to inconveniences such as malfunctions due to rusting of irons and sore throats due to the use of humidifiers.

Therefore, it may be possible to change the design of industrial water purifiers for home use, but in order to use them easily at home, they must be connected to a water pipe faucet. In order to purify all the tap water that is discharged, a large amount of ion exchange resin is required, making it large and expensive, making it unsuitable for household use, and water simply passing through the ion exchange resin. With this configuration, the amount of water varies depending on changes in tap water pressure and the degree to which the tap is opened, so there is a problem that the purity is not constant.

(Means and effects for solving the problem) This idea was made in view of the above-mentioned conventional problems, and the upper end opening is the attachment part to the water pipe faucet etc., and the lower end opening is the outlet for pure water. An ion exchange resin is filled in a thin tubular exterior tube, and an orifice is installed above the ion exchange resin in the exterior tube, and an overflow tube is connected and branched from a position above the orifice. The main points are as follows.

With the above configuration, only a certain amount of water is injected into the ion exchange resin at the orifice, regardless of the amount of water discharged from the water pipe faucet, and excess water is discharged from the overflow pipe, so that it is not injected into the ion exchange resin. Since only a small amount of water always passes through it,
Highly pure water can always be obtained using a small amount of ion exchange resin.

(Embodiments) Hereinafter, preferred embodiments of this invention will be described in detail with reference to the drawings.

In the figure, 1 is a thin tube-shaped exterior tube that serves as the main body, and the main body tube 1a is filled with ion exchange resin 2.
, a connecting pipe 1c in which the overflow pipe 1b is communicated and branched into a T-shape, and an attachment pipe 1d whose upper end opening is the attachment part to the water pipe faucet 3 are successively connected, and the main body pipe 1a is A take-out socket pipe 4 having a take-out port 4' for dripping pure water is attached to the lower end opening. The ion exchange resin 2 is of a mixed bed type in which a calculated amount of a cation exchange resin and an anion exchange resin are mixed respectively. The net 6 is also placed on top of the ion exchange resin 2. At the upper position of this net 6, the orifice 7 is connected to the main body pipe 1.
The orifice 7 is fitted into the inner wall of the tube 1c, and the orifice 7 is communicated with the connecting pipe 1c.

The water purifier having the above structure is used by attaching the upper end to the water pipe faucet 3 and suspending it, and then opening the water faucet and injecting tap water whenever necessary. . A constant amount of tap water discharged from the faucet 3 is constantly dripped into the main body pipe 1a by the orifice 7, passes through the ion exchange resin 2, becomes pure water, and drips from the outlet 4', and excess water is removed. is discharged to the outside from the overflow pipe 1b.

It should be noted that this invention is not limited to the above-mentioned embodiment, and it goes without saying that various embodiments can be considered without departing from the scope of the claims for utility model registration.For example, in the embodiment, the outer tube 1 is tube 1a,
Although an example is described in which the connection pipe 1c and the attachment pipe 1d are used, it may be formed from a single pipe or tube, or the water pipe faucet 3
In the above description, the tube can be attached to the water pipe faucet 3 by simply fitting the upper end opening of the mounting pipe 1d into the water pipe faucet 3. The attachment can be more securely achieved by attaching a known screw-type attachment.

(Effects of the invention) As mentioned above, according to the water purifier of this invention, although it is an easy-to-handle form that can be directly attached to a water pipe faucet due to the orifice and the overflow pipe provided above it, By passing a constant small amount of water through the ion exchange resin inside the thin tube-shaped exterior tube, the contact reaction between the tap water and the ion exchange resin is sufficient, regardless of changes in tap water pressure or the degree to which the tap is opened. , it is possible to always obtain high-purity pure water by making the most of the water purification ability of a certain amount of ion exchange resin, and since the amount of water passing through is constant, the purity is always constant, which is a remarkable effect. be. Incidentally, the pure water obtained with this invention has an electrical resistance that indicates its purity of 1 million Ωcm, compared to 0.73 Ωcm for ordinary tap water and 500,000 Ωcm for commercially available distilled water.
However, this purity remained unchanged. In addition, since the amount of water passing through is constant and it passes through the thin tube, the passage route is also approximately the same, so the contact area and contact time between water and ion exchange resin are also approximately constant, and the ion exchange resin is similar to the cation exchange resin. It is advantageous to be able to fill the container by either a two-bed (multi-bed) method in which the anion exchange resin and the anion exchange resin are individually packed, or a mixed bed method in which the calculated amounts of both ion exchange resins are mixed.

However, it has the advantage that it has a tubular appearance and can be constructed extremely easily with a small amount of ion exchange resin, is small and inexpensive, which is the most important requirement for household use, and can be made into a disposable product. This invention can provide an epoch-making home water purifier that exhibits the various extremely remarkable practical effects mentioned above.
