Abstract

PURPOSE:To improve the appearance of the periphery of a sink and to facilitate the operation of water feeding and stopping by integrating a nozzle for water cleaning with the body of a faucet. CONSTITUTION:The faucet 3 exists on the inlet side of a water cleaner 1. The passage of city water to the inside of the water cleaner 1 and the stoppage of the water passage are executed by the movement of a selector valve 6 which is operated by the operation of a selector lever 5. An inlet 15 of the faucet 3 communicates with a conduit 7 for the city water and an outlet 16 communicates with an inlet 10 of the water cleaner 1. The periphery of the sink looks good in this way and the clean water appears as if the water passes the faucet and, therefore, the operation of the water feeding and stopping is easy. The nozzle 4 for water cleaning connected to an outlet side piping 9 of the water cleaner 1 is integrated to the body of the faucet 3 without being connected to other pipings and the water cleaner is so operated that the clean water flows directly out of this faucet.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a water purification system suitable for purifying tap water.

[Conventional technology]

As home water purifiers, stationary types and types that connect directly to the faucet have been known for a long time, and these water purifiers use adsorbents such as activated carbon, activity, and hollow fiber filtration membranes for purification. A combination is used.

In addition, recently, under-sink type sinks have been proposed to avoid spoiling the beauty of the area around the sink (1986-
No. 176216, Utility Model Application Publication No. 1-1600 (No. 52).

[Problem to be solved by the invention]

However, in conventional under-sink type water purifiers, the water tap and water purification nozzle are located far apart, so the appearance around the sink is not always good, and the water supply and water shutoff operations are also inconvenient.

[Means to solve the problem]

The gist of the present invention is a water purifier 1 placed below a sink, a check valve 2 placed in the middle of a tap water pipe, and a water tap placed between the check valve 2 and the inlet of the water purifier 1. 3, and a water purification nozzle 4 connected to the outlet side piping of the water purifier 1, in which the water purification nozzle 4 is integrated into the main body of the water tap 3.

Hereinafter, the water purification system of the present invention will be explained with reference to the drawings.

FIG. 1 shows an example of a water purification system according to the present invention, in which a water purifier 1 is placed below a sink 14. As shown in FIG. The water purifier 1 consists of a container body and a water purification cartridge containing an adsorbent such as activated carbon or a hollow fiber filtration membrane.

As the hollow fiber filtration membrane, known ones such as those made of polyethylene or polysulfone are used, and as the activated carbon, granular activated carbon or the like is used.

FIG. 2 is a diagram showing an example of a water tap. The water tap 3 is located on the inlet side of the water purifier 10, and the flow of tap water into the water purifier 1 is stopped by moving a switching valve 6 activated by operating a switching lever 5. The inlet 15 of the faucet 30 communicates with the tap water conduit 7, and the outlet 16 communicates with the inlet 10 of the water purifier 1.

A check valve 2 is provided on the upstream side of the faucet 3 to prevent backflow of tap water to the conduit side. This check valve may be built into the faucet main body. A water purification nozzle 4 connected to the outlet side piping 9 of the water purifier 1 is integrated into the main body of the faucet 3 without being connected to other piping, so that purified water flows directly from the faucet. be operated on. A silver mesh may be placed at the outlet of the water purification nozzle to prevent back contamination, and the inner surface of the nozzle may be coated with silver.

An inlet side pipe 8 and an outlet side pipe 9 are respectively connected to the inlet part 10 and outlet part 11 of the water purifier. Fittings 12.1! When the water purification capacity decreases, it is easy to replace the IJ connection. Further, it is preferable that these joints are provided with automatic opening/closing valves to prevent water from leaking from the piping during attachment and detachment.

〔Effect of the invention〕

The water purification system of the present invention has an under-sink type, and the water purification nozzle is integrated with the faucet, so the area around the sink looks good, and it looks like purified water is flowing out through the faucet, so the water supply It is easy to operate the water stop. or,
Since the water purifier is a main stop type in which the water tap is placed upstream of the water purifier, the water purifier can be used even in a container with low pressure resistance, and the cost of the water purifier can be reduced.

Furthermore, if the water purifier has a structure in which the inlet and outlet are connected by a removable joint, the main body of the water purifier can be easily replaced.
