[Industrial applications]

 The present invention relates to a water purifier for removing hardness components contained in well water and tap water, and an odor of chlorine contained in tap water.

[0002]

[Prior art]

Water containing a relatively large amount of calcium and magnesium ions dissolved therein is called hard water, and water containing a small amount of these is called soft water. The degree of hard water is expressed in terms of hardness. In Japan, 100 cm ³ of water contains 1 mg of calcium oxide as 1 degree, and magnesium is converted to calcium oxide based on the relationship of “1.4 MgO = 1 CaO”. Usually, 20 degrees or more is called hard water and 10 degrees or less is called soft water. Hard water is used for sake brewing, but it is not suitable for drinks, and soap is difficult to foam, so its utility value is low.

Further, tap water uses well water as well as water taken from rivers, etc., but rivers, lakes, groundwater, etc. are contaminated by factory wastewater and domestic wastewater more than expected. However, it costs a huge amount of money to disinfect a large amount of chemicals, and it has a strong odor of chlorine, which makes it unsuitable for drinking.

Therefore, conventionally, a water purifier using an ion exchange resin has been used to use water softened by removing hardness components for home use or the food industry, and to remove odor and cloudiness. A water purifier that uses a filter medium such as activated carbon is used for.

FIG. 3 is a partial cross-sectional view showing an example of a conventional water purifier filled with an ion exchange resin. This water purifier is attached by welding a cylindrical cover 1b and a bottom 1c of the same to the upper and lower sides of a stainless steel cylindrical body 1a, and a porous net 1d is stretched on the bottom of the body 1a. Then, the ion exchange resin 2 is filled on it.

Further, a cap 3 is attached to the upper surface of the lid 1b, a plug 4 to which a water faucet or a hose or the like is attached is screwed to the cap 3, and a socket is provided on the lower surface of a bottom 1c formed in a box shape. Attach 5. Further, it has a structure in which annular rubber rings 6a and 6b for impact prevention are attached on the outer peripheral surfaces above and below the currant body 1a, respectively.

In this structure, when the well water or the tap water flows in from the plug 4, the water flows down while contacting the ion exchange resin 2 to the Calan bottom body 1c, and the hardness component as well as the lead and mercury due to the ion exchange action. , Heavy metals such as hexavalent chromium and cadmium are completely removed and flow out from the socket 5 as soft water.

[0008]

[Problems to be solved by the device]

 By the way, since the capacity of the ion exchange resin is about 1 to 2 tons of water per liter of the resin, it must be exchanged or activated (regenerated) on a regular basis. However, if the curran bottom body 1c is formed in a box shape, the water flowing from above the ion exchange resin 2 mainly flows down along the inner peripheral wall of the curran main body 1a, so that the resin in the peripheral portion is in the central portion. The resin is consumed faster than the above resin, and there is a disadvantage that the entire resin must be replaced despite the fact that the resin in the central portion has the replacement capacity.

In addition, a water purifier using an ion exchange resin can activate the resin. For this activation, salt water is made to flow down from the plug 4 into the Karan body 1a, and the salt water is brought into contact with the resin 2 so that sodium ion Is attached to the resin 2. However, in this case as well, salt water mainly flows down along the inner peripheral wall of the Karan main body 1a, which makes it difficult to uniformly activate the resin 2.

Further, as shown in FIG. 4, although there is a case where the shape of the curran bottom body 1c is formed in a funnel shape, in this case, the water flowing in from the upper side causes the central portion of the curran main body 1a to flow. Since a straight passage that goes straight and flows down to the Karan bottom body 1c is easily formed, the central part of the ion exchange resin 2 is consumed faster than the peripheral part, contrary to the above example, and the resin in the peripheral part is Despite the exchange capacity, there is the inconvenience of having to replace the entire resin. Even when the resin 2 is activated, the salt water mainly goes straight through the central portion of the Karan main body 1a, which makes it difficult to uniformly activate the resin 2. The same applies to water purifiers that use filter media such as activated carbon.

Therefore, the purpose of the present invention is to allow water to flow down evenly in the currant body, to uniformly consume the water purifying ability of the ion exchange resin or the filter medium filled in the vessel, and consequently to extend the life of the ability. To do.

[0012]

[Means for Solving the Problems]

 The water purifier according to the present invention is provided with a main body of a coin filled with ion exchange resin or a filtering material, a top cover of the main body of the main body having an inflow port at the top, and a bottom face of the main body of the main body of the water. It is composed of a hemispherical Karan bottom with an outlet on the bottom.

In addition, the water purifier according to the present invention includes a curran main body having an ion exchange resin or a filtering material filled therein, and a curran lid installed on the upper surface of the curran main body and having a porous member inside the upper surface. It is composed of a body and a hemispherical bottom body of a curran, which is installed on the lower surface of the curran body and has an outlet on the bottom.

[0014]

[Action]

 In the structure of the present invention, when water is introduced from the inflow port of the calan lid, the force of the water is killed by the porous member, and the water is dispersed entirely on the surface of the ion exchange resin or the filtering material. Also, because the currant bottom body is formed in a hemispherical shape, the water that has dropped onto the surface of the ion-exchange resin or the filter medium flows down in a spiral shape while flowing evenly and evenly through the currant body. , As hard water from which hardness components and heavy metals have been removed, or as water from which odor and turbidity have been removed, falls on the currant bottom body. As a result, the capacity of the resin or the filtering material in the container is uniformly consumed as a whole, and only a part of the capacity is not consumed as in the conventional case, and as a result, the capacity life can be increased.

【Example】

 1 and 2 are a partial cross-sectional view and a perspective view showing an embodiment of a water purifier according to the present invention filled with an ion exchange resin. The same parts as those shown in FIG. 3 are designated by the same reference numerals. To do.

In this embodiment, except that a mesh net 7 made of porous resin or stainless is attached to the lower portion of the cap 3 as a porous member, and the currant bottom body 1c is formed in a hemispherical shape, It has the same configuration as that shown in FIG.

In this configuration, when well water or tap water is poured from the faucet 8 attached to the plug 4, the water is totally dispersed on the surface of the ion exchange resin 2 while the momentum is killed by the mesh net 7. Then, since the curran bottom body 1c is formed in a hemispherical shape, water flows down in the ion exchange resin 2 in a spiral shape and passes through the ion exchange resin 2 evenly and uniformly. To fall. The water that has fallen on the currant bottom body 1c flows out through the cock 9 and the faucet 10 attached to the socket 5, and flows out as soft water from which hardness components and heavy metals have been removed.

Also, when salt water is made to flow down in order to activate the ion exchange resin 2, the salt water can evenly and uniformly pass through the ion exchange resin 2 and the resin 2 can be uniformly activated.

In the above-mentioned embodiments, the case where the present invention is applied to the water purifier filled with the ion exchange resin is described, but even when the present invention is applied to the water purifier filled with the filter medium such as activated carbon. According to the same principle, water flows down in a spiral shape in the filter medium, uniformly and evenly passes through the filter medium, and falls on the Karan bottom body 1c.

Further, in the above-described embodiment, the case where the currant main body is used in the vertical direction has been described, but it may be used by tilting sideways or lying down horizontally. When using it lying down on the horizontal surface, it is necessary to inject water at a high pressure from the inlet, but the air accumulated in the resin will accumulate along the upper peripheral wall, increasing the water purification capacity. become.

[0021]

[Effect of device]

 According to the present invention, water uniformly and evenly passes through the ion exchange resin or the filter medium filled in the body of the currant, so that the ability of these filled members is uniformly consumed, and as a result, the ability life is increased. It becomes possible.
