Abstract

(57) [Summary] (Correction) [Purpose] To provide a thin, compact household water purifier that can check the dirt of the filter from the outside. [Structure] When the raw water is used as it is without being purified, the water flows from the inflow port 1 to the inflow port 2, through the water passage 3 at the center of the cylinder by the switching lever, and from the outflow port 4 in the shape of a shower. When performing water purification, switch the switching lever to the water purification side. Water enters through the water inlet 5, passes through the adsorbent packed bed 6,
The filter 8 in the transparent case 10 passes through the slit 7.
And flows straight out of the outlet 9.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a household faucet direct connection type water purifier.

[0002]

[Prior art]

 Conventional household faucet direct connection type water purifiers are known in which adsorbents such as activated carbon and filters such as hollow fiber membranes are arranged in series, or adsorbents are arranged concentrically outside the filter. There is.

[0003]

[Problems to be solved by the device]

 However, if the adsorbent and the filter are arranged in series in a cylindrical water purifier just below the faucet, the water purifier itself becomes vertically long and becomes a hindrance to water work for housewives at home, impairing usability.

Therefore, it is possible to obtain a flatter shape by arranging the adsorbents concentrically on the outer side of the filter, but when it is considered to be made of a transparent material, it is arranged on the inner side. The condition of the filter cannot be visually confirmed.

[0005]

[Means for Solving the Problems]

 The present invention is a directly connected faucet type water purifier having a cylindrical shape just below the faucet, and has a filter inside the cylinder and a concentric circular adsorbent inside the cylinder with respect to the direction of raw water inflow. And in the water purifier.

The filter is used for general water purifiers such as hollow fiber membranes, ceramics, antibacterial resins, etc., and its amount does not have to occupy the entire outer layer in the cylinder, and can be changed as needed. Good.

The adsorbent is also used in general water purifiers such as granular activated carbon, silver-impregnated activated carbon, fibrous activated carbon, calcium sulfite, ion exchange resin and activated carbon in combination, and the amount thereof is the inner layer in the cylinder. It is not necessary to occupy all of them, but you can change them as needed.

[0008] The inner layer of the cylinder has a portion filled with an adsorbent such as activated carbon in the raw water inflow direction, a water passage for bypassing the raw water at the center of the cylinder, and a shower outlet at its end.

The inner and outer layers of the cylinder have a portion filled with a filter such as a hollow fiber membrane, and the surface of the cylindrical portion containing the filter is made of a transparent resin. By providing such an array of filter media, a water passage, and a cylindrical surface, it is possible to provide a water purifier that is thin and small, and that allows the dirt of the filter to be seen from the outside.

【Example】

 Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 is a sectional view of a faucet direct connection type water purifier of the present invention, FIG. 2 is a sectional view taken along the line AA ′, and FIG. 3 is a front view of the water purifier.

When the raw water is used without being purified, the switching lever 11 of the water purifier is switched to the raw water side. Water flows from the inflow port 1 through the inflow port 2, the water passage 3 in the center of the cylinder, and then outflows from the outflow port 4 in a shower shape.

When performing water purification, the switching lever of the water purifier is switched to the water purification side. Water enters from the water inlet 5, passes through the adsorbent filling layer 6, passes through the slit 7, passes through the filter 8 in the transparent case 10, and flows out straight from the outlet 9.

[0013]

[Effect of device]

 By using the present invention, it is possible to provide a thin and compact household water purifier in which the contamination of the filter can be confirmed from the outside.
