Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water purifier for removing red rust in tap water.

[0002]

2. Description of the Related Art This type of water purifier is installed between, for example, a large-scale water purifier for home use and a hose that connects a faucet, and its conventional structure is to fill a filter inside a metal cylinder and A connecting member for connecting to the hose is detachably attached to both ends of the. By the way, the filter used in this type of water purifier cannot be used semi-permanently, and its purification capacity gradually decreases in proportion to the amount of water used, and eventually it becomes impossible to remove red rust, so the user It is necessary to replace it with a new filter at the right time. As a guide for the replacement time, the product's instruction manual states, for example, "If you use 10 liters a day, replace it in 6 months, and in places with poor water quality, replace it in 1 to 2 months". There is.

[0003]

However, the amount of water used varies depending on the household, and the content of red rust contained in the water varies depending on the region.
If the standard display is used as a guide, the filter cannot be replaced at an appropriate time. As a result, it was possible to use unsanitary water with red rust mixed in the water without changing the filter, and replace the filter with the remaining purification capacity with a new one. There was also a waste of resources.

Therefore, the present invention provides a water purifier capable of accurately knowing when to replace the filter, and solves the above-mentioned problems.

[0005]

SUMMARY OF THE INVENTION The present invention is a water purifier for removing red rust of tap water, in which a white filter is filled inside the tubular body and a connecting member is inserted into and removed from at least one end of the tubular body. It is freely attached, and the cylindrical body is formed transparent. Note that at least in the above expression means that the connecting members may be removably attached to both ends of the tubular body.

[0006]

[Operation] Water flows into the inside of the cylinder through the connecting member, the red rust is removed by the filter and flows out of the cylinder, so that the filter gradually accumulates red rust and gradually changes color from white to reddish brown. Since the cylinder to be filled is transparent, it is possible to visually recognize the discolored state of the filter, and it is possible to determine the deteriorated state of the purification capacity from the discolored state, so that the replacement time can be accurately known. Further, the tubular body can be detached from the connecting member, and the filter can be taken out from the tubular body and refilled with a new one.

EXAMPLE A water purifier 1 of the present invention is attached to a faucet j, a hose h or the like.

FIGS. 1 and 2 show the structure of the water purifier 1 when it is attached to a hose h, in which a white filter 3 is filled inside a tubular body 2 and connecting members are provided at both ends of the tubular body 2. 4 is screwed in and attached.

The cylindrical body 2 is a transparent molded product made of synthetic resin or glass, and the inner diameter of the water outflow end is narrowed so that the filter 3 does not flow out under water pressure. Be prepared. The white filter 3 is for removing red rust, and is made of a non-woven fabric or a bottomed cylindrical ceramic.

The connecting member 4 is a joint 8 in which a pocket portion 6 for accommodating the distal end portion of the hose h and a cap portion 7 for screwing the thread groove 5a of the cylindrical body 2 are integrally molded, and a nut 10 is inserted via a sleeve 9. By screwing in, the tip of the hose h is tightened with the sleeve 9 so that the tip of the hose h does not come off the pocket 6 and water leakage is prevented.

The joint 8 has a cap portion 7 which is formed by connecting a ring-shaped stopper 12 for narrowing the inner diameter to one end of a tubular nut portion 11 that fits the thread groove 5a of the cylindrical body 2. The tubular pocket portion 6 is formed between the small pipe portion 13 penetrating the stopper portion 12 in a continuous state with the large pipe portion 14 continuous to the middle portion of the stopper portion 12, and the large pipe portion 14 is A thread groove 5b is formed on the outer periphery thereof, and the inner diameter of the tip end portion thereof is tapered so as to widen toward the tip end.

The sleeve 9 has the same inner diameter as that of the large pipe portion 14, and has an annular projecting piece having a taper fitted at one end of a pipe 15 having a thickness smaller than that of the large pipe portion 14 so as to be fitted to the end portion of the large pipe portion 14. 16 is formed.

The nut 10 has a thread groove 5b in the large pipe portion 14.
The ring portion 18 for narrowing the inner diameter is connected to one end of the large pipe nut portion 17 that fits the inner diameter of the large pipe nut portion 17. The inner diameter of the ring portion 18 is formed slightly larger than the outer circumference of the tube 15 of the sleeve 9. Reference numeral 19 in the figure is a packing for preventing water leakage.

FIG. 3 shows a usage example in which the water purifier 1 having the above-mentioned structure is attached between the hoses h connecting the faucet j and the large water purifier w.

FIG. 4 shows an embodiment in which the water purifier 1 is attached to the faucet j. In this case, the connecting member 4 is attached only to the upper end of the tubular body 2, and the lower end of the tubular body 2 has a water passage port. A lid 20 provided is provided, and a connection adapter 21 that connects both 4, j is provided between the connection member 4 and the faucet j.

In the water purifier 1 of the present invention, water passes through the connecting member 4 and flows into the inside of the cylindrical body 2, the red rust is removed by the filter 3, and the water flows out from the cylindrical body 2. Therefore, the filter 3 accumulates red rust. Gradually changes from white to reddish brown, and the cylinder 2 that fills this filter 3 is transparent.
It is possible to visually grasp the discoloration situation of. Therefore, when the discoloration of the filter 3 reaches a certain standard, it can be determined that the purifying ability of the filter 3 is significantly reduced and the red rust cannot be removed, so that the replacement time can be accurately known.

[0017]

Since the water purifier of the present invention has a transparent cylinder and a white filter, it is possible to visually recognize the discoloration state of the filter and to judge the deterioration state of the purification capacity from the discoloration state. Therefore, if you replace the filter at the time of replacement, you can always use sanitary water,
It is very useful that the filter can be used without waste until it loses its cleaning ability.
