Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a water-purifying device for purifying tap water, rainwater, and other water to be drunk mainly for drinking to obtain water that is preferable for health. , Homes or clinics, schools,
The present invention relates to a water sprinkler for drinking water suitable for installation in restaurants, hotels and the like.

[Conventional technology]

Conventionally, as a water passing device of this type, materials C, D, and E which form a cylindrical main body (A) shown in FIG. It is known that F is stored.

Wood, D, E, and F are sand, gravel, activated carbon,
In some cases, it is gravel, and in some cases it is also used in combination with an ion-exchange resin or the like (very commonly known in elementary and secondary textbooks).

[Problems to be solved by the device]

In recent years, since the pollution of raw water has been severe, tap water usage has increased, causing an abnormal odor of chlorine. Also, Mansion,
Due to dirt inside water tanks of buildings and the like, the quality of water discharged from the faucet of terminals has become a serious health problem.

Therefore, even in general households, there is a tendency that the water coming out of the faucet is used for drinking or cooking after passing through a small water passing device.

All of the conventional techniques described above are those in which the water to be passed is taken out by passing it into the over chamber of a specified volume. It is irrational to do so. On the other hand, there is a problem in that the manufacturer has to manufacture and store multiple models having different capacities, which requires an uneconomical manufacturing plan to meet the demand.

The present invention has been made in view of the above-mentioned problems of the conventional technology. The purpose of the present invention is to minimize the number of manufacturing models and to easily assemble and disassemble. Furthermore, the present invention intends to provide a water passing device capable of performing an optimum water passage according to the water quality.

[Means for solving problems]

In order to achieve the above-mentioned object, the water passing apparatus according to the present invention is provided with a water chamber having an outflow port at the upper side beside the over chamber having a permeated water inlet at the upper side, and A water chamber with an outlet is provided on the side of an excess chamber which has a unit for the first stage in which both of them are communicated with each other in the lower portion and an inlet which can be connected to the above-mentioned outlet in the upper portion. And a unit for the final stage in which both of them are communicated at the bottom.

Between the unit for the first stage and the unit for the final stage, one unit or a plurality of units for the intermediate stage are connected in series as necessary to increase the volume of the excess chamber, while each unit is increased. Is preferably in the shape of a substantially rectangular tube.

In addition, it is preferable that each unit is a male and female unit for facilitating the coupling and assembling, and that the top of each unit is closed by a watertight lid to simplify the maintenance.

[Action]

The unit for the first stage is supplied with perfused water through the perfused water inlet (for example, tap water supplied from a tap)
However, after entering the over chamber of this unit and being purified as it flows down in the over chamber, it enters the water chamber on the side from the lower part of the over chamber. The water that has entered this water chamber exits from the upper outlet of this water chamber, passes through the inlet of the next unit, and enters the over chamber of that unit (for example, when a unit for an intermediate stage is interposed). , From the unit for the first stage to the unit for the intermediate stage).

The unit for the intermediate stage has an inlet that can be connected to the outlet of the unit for the first stage, and this unit for the intermediate stage is provided with an outlet that can be connected to the inlet of the unit for the final stage. Therefore, the water to be permeated reaches from the unit for the first stage to the unit for the final stage through the unit for the intermediate stage. Then, it is taken out from the water chamber of the unit for the final stage.

Of course, if the unit for the first stage and the unit for the final stage are directly connected, the water to be permeated will pass from the excess chamber of the unit for the first stage through the water chamber of this unit to the unit for the final stage. It enters the excess chamber and is taken out of the water chamber with outlet of this unit.

In other words, in the case of excess water with excellent specific water quality, the unit for the first stage and the unit for the final stage are integrally connected in series, and the excess in both units is sufficient. It will be.

If the water to be treated is poor in specific water quality (for example, tap water with an unusually high odor of chlorine), there are two or three intermediate-stage units between the first-stage unit and the final-stage unit. The volume of the excess chamber used by interposing is increased.

If each unit can be connected to male and female, it is extremely easy to assemble, and it is also very easy to replace a unit with inferior ability.

In addition, the top of each unit is closed with a watertight lid, and by removing it, the internal maintenance can be performed very easily.
