Shower apparatus

A hot and cold water mixing device which comprises one or more valve units each constituted by accommodating an operating member within a hollow casing, and a housing into which the one or more valve units are inserted and arranged and in which two primary water passages communicating with a hot water supply source and a cold water supply source, respectively, are formed. The housing is composed of an outer housing (1) and an inner housing (2) which is inserted into the outer housing and which is formed with water holes (11,12,13) communicating with said valve units, and at least two primary water passages (5,6) are formed between the outer housing and the inner housing by separating members (3). Further, since the hot water passage (5) and the cold water passage (6) are formed between the outer casing (1) and the inner housing (2) using separating members (13), the primary water passages can easily be formed and, simultaneously, the construction of the mixing device can be simplified and the assembling and disassembling operations can be facilitated.

In a combination faucet device (10) according to the invention, a movable valve member (160) slidingly moves relative to a main casing (30) to change a mixing ratio of high-temperature water supplied from a hot water port (116) to low-temperature water supplied from a cold water port (106). The movable valve member (160) is pressed by a temperature sensitive spring (130) in a first direction while being pressed by a bias spring (150) in a second direction opposite to the first direction. The temperature sensitive spring (130) is exposed to a water mixture and varies its spring constant according to the temperature of the water mixture. The temperature sensitive spring (130) accordingly moves the movable valve member (160) in a direction for decreasing the ratio of the high-temperature water to a certain position where the spring force of the temperature sensitive spring (130) balances with the spring force of the bias spring (150), thus allowing a water mixture adjusted to a target temperature.

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.

Hot and cold water mixing discharge device

A bubbly water outlet device comprises a swirl chamber which is connected to a water supply source and is adapted to swirl a flow, and a bubbler chamber which is connected to the swirl chamber through a discharge port provided substantially at a center of the swirl chamber. The bubbler chamber is adapted to suck air from an exterior by virtue of the inflow of water from the discharge port and is capable of discharging bubbly water.
