【Example】

 Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an overall perspective view of a simplified water purifier according to an embodiment, and FIG. 2 is a sectional view taken along the line AA in FIG. As shown in FIG. 1, this water purifier is obtained by integrally connecting a filtration unit 20 to a main body 10, and the main body 10 is directly connected to a faucet 30 such as a tap. A raw water inlet 11 is provided at an upper portion of the main body 10, and the raw water inlet 11 is connected to a faucet 30 via a nut 12. A raw water outlet 13 is provided at a lower portion of the main body 10, and a purified water outlet 21 is provided at a side portion thereof. Further, as shown in FIG. 2, a water supply passage 14 and a water discharge passage 22 are formed diagonally rearward from the side of the main body 10, and each of the water passages 14, 22 is arranged in a vertical position at the back of the main body 10. The communication part is connected to the lower part of the filtered part 20.

In the present embodiment, the filtering unit 20 is disposed approximately 45 ° obliquely behind the main body 10. That is, as shown in FIG. 2, the angle θ formed by the straight line B connecting the center of the raw water inlet 11 and the center of the filter unit 23 and the center line C of the flow path switching valve 14 becomes 45 °. Have been placed. However, the present invention is not limited to this arrangement position. To achieve the object of the present invention, the angle θ, or a straight line B connecting the center of the raw water inlet 11 and the center of the filter unit 23, The angle θ formed by the straight line passing through the center of the raw water inlet 11 to the main body 10 and traversing the main body 10 when the faucet is connected is preferably 20 ° to 75 °, more preferably 30 ° to 60 ° rearward. It is better to arrange them so that This is because if the angle is less than 20 °, the effect of the present invention is small, and if the angle exceeds 75 °, it is often difficult to connect to the faucet 30.

A flow switching valve 14 is housed in the main body 10, and the flow switching valve 14 is operated by a lever 15 provided on a side portion of the main body 10. When the lever 15 is set to the “raw water” position, the raw water taken in from the raw water inlet 11 is discharged from the raw water outlet 13. When the lever 15 is set to the “purified water” position, the raw water taken in from the raw water inlet 11 is supplied to the filtration unit 20 via the water supply passage 14, and the purified water purified by the filtration unit 20 is discharged from the water discharge passage. The water is sent to the main body 10 via the outlet 22 and discharged from the water purification outlet 21. The configuration of the flow path switching valve 14 is the same as that of the conventional example, and is not the gist of the present invention, so that the description thereof is omitted.

The filtering section 20 includes a detachable filter unit 23 and a cap 24 for accommodating the filter unit 23. The filter unit 23 includes an outer layer 25 made of an adsorbent such as activated carbon, and an inner layer 26 (hollow fiber membrane layer) filled with a hollow fiber membrane.

The raw water sent from the water supply passage 14 is guided to the outer layer 25, where the adsorbent adsorbs calcium, organic matter, and the like. The raw water that has passed through the outer layer 25 is further guided to the inner layer 26, where fine impurities such as bacteria, iron rust, and mold are removed by the hollow fiber membrane. Then, the purified water that has passed through the inner layer 26 and purified passes through the water discharge channel 22 and is discharged from the purified water outlet 21 provided at the lower part of the main body 10.
