  • the state in which the water purification discharge is being performed in the switching cock 100 for water purifier is shown in FIG. 8 and FIG. 11, and the switching handle 50 is pivoted so as to protrude upward as shown in FIG. .
  • the first ball valve body 41 and the second ball valve body 42 normally close the valve seat 31 and the shower valve seat 32 by their own weight, and the third ball valve body 43 is formed in the purified water discharge passage 23 It is pulled up from the purified water valve seat 33 by a certain third raising portion 26, and the purified water discharge port 14 is in an open state.
  • the raw water of the faucet 210 supplied from the raw water port 11 passes through the metering plug 12 a of the raw water supply port 12 and is supplied into the water purifier 300, and the raw water is collected in the water purifier 300. Purification is performed, and the water is returned to the side of the water purifier switching cock 100 through the connection hose 310. And since the purified water discharge port 14 is open
  • the selective opening and closing of the clean water discharge port 14, the normal discharge port 15, and the shower port 16 is performed by the normal valve seat 31, the shower valve seat 32, and the clean water Since the first ball valve body 41, the second ball valve body 42 and the third ball valve body 43 are pulled up on the valve seat 33 and placed by their own weight, for example, the cock body 10 and the switching rotary element If compared with the opening and closing by sliding contact with 20, the seal structure can be simplified, the structure can be simplified, and the durability can be made high.
  • the water purification outlet 14 is opened downward, and the water purification valve seat 33 is made horizontal, and the opening and closing of the valve opening 33 a of the water purification valve seat 33 is described above. Since the third ball valve 43 is used, it is possible to block the entry of air when the purified water is not being discharged.

Abstract

L'invention concerne un robinet commutateur qui : est capable d'effectuer trois types de commutation, vers une distribution normale, une distribution de douche et une distribution d'eau purifiée; a une structure simple et est capable d'empêcher l'entrée d'air qui peut devenir une source de microbes contaminants; coupe efficacement l'eau après utilisation; et permet un ajustement facile de la pression. Le corps principal du robinet (10) comprend un orifice d'entrée d'eau brute (11), un orifice de distribution d'eau brute (12), un orifice d'entrée d'eau purifiée (13), un orifice de distribution d'eau purifiée (14), un orifice de distribution normale (15), et un orifice de douche (16). Le système rotatif de commutation (20) comprend, à des positions respectives dans la direction circonférentielle : un passage de distribution normale (21) qui permet sélectivement à l'orifice d'eau brute (11) de communiquer avec l'orifice de distribution normale (15); un passage de distribution de douche (22) qui permet sélectivement à l'orifice d'eau brute (11) de communiquer avec l'orifice de distribution de douche (16); et un passage de distribution d'eau purifiée (23) qui permet sélectivement à l'orifice d'entrée d'eau purifiée (13) de communiquer avec l'orifice de distribution d'eau purifiée (14). Une vanne de réglage de pression (70) est située dans l'orifice d'eau brute du corps principal de robinet (10), la vanne de réglage de pression étant constituée d'une base (71), d'une plaque circulaire (72) intégrée à ladite base (71), d'une pièce circulaire inclinée (73) qui est intégrée au bord intérieur de la plaque circulaire (72) et dont l'extrémité pointue (73a) est inclinée vers le premier côté du canal d'écoulement, et d'un trou traversant (74) formé dans le côté de l'extrémité pointue (73a) de la pièce circulaire inclinée (73).
