An automatic temperature control means 16 for automatically generating a mixed warm water of prescribed temperature by mixing an introduced hot water from a hot water inflow passage 14 and an introduced cold water from a cold water inflow passage 12 with each other at a flow rate ratio corresponding to the prescribed temperature, and a flow rate control means 19 for regulating the temperature of the discharged mixed warm water by mixing it with a hot or cold water introduced from the hot or cold water inflow passage 14 or 12 through a by-pass 18 around the former means are provided. As a result, mixed warm water of desired temperature can be easily obtained by manipulating the flow rate control means 19.
A hot and cold water mixing faucet in which a handle having a lever is supported by the body of said faucet over said body so that said handle can be vertically swung with the lever thereof to regulate the flow rate of a warm water about to be discharged from a discharge port, and can be horizontally turned with said lever to regulate the temperature of said water about to be discharged from said port, including a stopper means for preventing said handle from being turned beyond a prescribed position in such a direction as to heighten said temperature;
A hot and cold water mixing faucet in which a handle having a lever is supported by the body of said faucet over said body so that said handle can be vertically swung manually with the lever thereof to regulate the flow rate of warm water about to be discharged from a discharge port, and can be horizontally turned manually with said lever to regulate the temperature of said water about to be discharged from said port, wherein the range of the swinging or turning of said handle consists of an ordinary quantity discharge portion extending from a valve closure position to a boundary position, and a large quantity discharge portion extending from said boundary position to a valve entire opening position;
