Abstract

PURPOSE:To obtain a water purifier of simple structure having a long service life by arranging a spool main body provided with an O ring so that the main body is selectively inserted into a small-diameter part or into the inner diameter of a spool sleeve without the O-ring being abutted on the communicating edge with a vertical water passage. CONSTITUTION:A spool main body 21 provided with an O-ring 25 is inserted selectively into a small-diameter part 7g or into the inner diameter of a spool sleeve 20 so that the flow of a horizontal water passage 7c is switched, hence the O-ring 25 provided to the main body 21 is not abutted on the communicating edge between a vertical water passage 7i and a large-diameter part 7f, and the O-ring 25 is not damaged. Consequently, the service life of a water purifier 2 is remarkably prolonged.

Next, when the purified water is taken out, the dial portion 22 is pulled and the O-ring 25 is attached to the spool sleeve 20.
When contacting the arc surface of the tip portion 20d of the horizontal passage 7c, the communication of the horizontal water passage 7c to the left side of the spool sleeve 20 is closed, and the communication portion 7i on the inlet side of the vertical water passage 7d and the spool sleeve 20 of the horizontal water passage 7c on the right side. Communicates with. When the faucet 1 is opened in this state, the raw water of the tap water flows from the vertical water passage 7d to the horizontal water passage 7c to the purified water inlet passage 7e and flows as shown by a dotted arrow in FIG. That is, the raw water is the purified water introduction path 10a.
The check valve 11 is pushed up to reach the lower surface of the sealing lid 12 and penetrates into the activated carbon 14 through the hole 13a of the activated carbon retainer 13 and is purified at this portion and passes through the filter 5 to the purified water outlet passage 7k. It flows out as purified water.

When the water purification function of the cartridge 8 deteriorates, specifically, when the water purification function of the activated carbon 14 deteriorates, the cartridge 8 is replaced. The replacement is performed as follows. First, the cartridge cover 9 is removed from the cartridge receiving portion 7b. Then the cartridge 8
Is lifted upward and removed from the cartridge receiving portion 7b. Then, a new cartridge 8 is attached to the cartridge receiving portion 7b from above. In this case, if the two mountain-shaped concave portions 10c provided on the outer peripheral side surface of the cartridge body 10 are engaged with the two convex portions 7L of the cartridge receiving portion 7b, the cartridge 8 is naturally attached to the predetermined position of the cartridge receiving portion 7b. be able to. That is, since the chevron-shaped recess 10c is provided on the outer peripheral side surface of the cartridge body 10, it can be easily confirmed by a person who replaces it. Further, since the concave portion 10c has a chevron shape with a wide entrance, even if the cartridge 8 is attached to the cartridge receiving portion 7b with a slight deviation from the correct position, the convex portion 7L can be inserted into the concave portion 10c, and thereafter, The position of the cartridge 8 is adjusted along the convex portion 7L. Further, the mountain-shaped concave portion 10c has an upper end portion having a lateral width portion 10c 'which is slightly wider than the lateral width of the convex portion 7L, and the height dimension L 1 thereof is a protrusion portion 10d provided on the lower surface of the cartridge body 10. Since 10e is set to be larger than the dimension L 2 that overlaps the purified water inlet passage 7e and the purified water outlet passage 7k, the protrusions 10d and 10e are fitted in the purified water passage 7e and the purified water outlet passage 7k in the vertical direction, and the fitting property is improved. Is good. Moreover, since the convex portion 7L is integrally provided on the inner surface of the cartridge receiving portion 7b so as to be vertically long, it has the effect of reinforcing the cartridge receiving portion 7b. Thus, according to such an embodiment, the large-diameter portion 7 is formed in the body body 7 which constitutes the body portion 3.
A horizontal water passage 7c having f and a small diameter portion 7g is provided, the small diameter portion 7g is communicated with the cartridge portion 4, the large diameter portion 7f is opened outside the body body 7, and the body water passage 7d has a large diameter water passage 7d. The spool sleeve 20 is provided so as to communicate with the portion 7f, and the spool sleeve 20 is disposed in the large diameter portion 7f. The large diameter portion 7f changes into the small diameter portion 7g without coming into contact with the communication edge portion between the vertical water passage 7i and the large diameter portion 7f. Since the spool body 21 including the O-ring 25 is movably arranged so as to selectively contact the continuous portion 7h and the spool sleeve 20 to switch the flow of the lateral water passage 7c, the O-ring 25 may be damaged. This eliminates the problem and the life of the water purifier can be remarkably extended. Since the O-ring 25 is wound concentrically with the spool body 21,
Does not float above the spool body 21. Moreover, since the O-ring 25 comes into contact with the smooth arc-shaped continuous portion 7h and the spool sleeve 20, the water-sealing property is good, and the O-ring 25 is hardly deteriorated due to wear. Even if the O-ring 25 is worn for many years, if the moving distance of the spool body 21 can be increased, the contact force required for water sealing can be always secured. At the time of outflow of raw water and the outflow of purified water, water pressure is applied to the O-ring 25 in a direction to make the water-sealing stronger, so that more reliable water-sealing can be performed and it is also effective against wear of the O-ring 25.
