Two linear mixing chambers with both ends open parallel to these flow paths are installed, and a chamber in the middle of these mixing chambers is divided into two via a rib and can be used for both hot water and cold water or cold and hot water. The two rooms are divided by parallel ribs, and each rib has a common socket, which automatically adjusts the temperature of the mixed water in response to the water temperature. A linear casing containing a thermostatic valve structure is configured to be able to be inserted and removed freely, and a rib and a bearing plug having the same inner diameter as the insertion port are attached to the outer ends of both mixing chambers. The casing is provided with a threaded opening, the two mixing chambers communicate with the two chambers through the inlet of the casing, and the mixing chamber communicates with a discharge pipe and a pipe joint leading to the shower head through the outlet of the casing. Adjacent both open ends of a shared hot water supply pipe and a branch pipe that communicates with the water supply pipe, which can be inserted and removed freely into the above-mentioned socket, and which have been buried in advance inside a common wall where bathrooms or washrooms of buildings are installed next to each other. The normally assembled hot and cold water mixing faucet is installed in the front pipe of one room, and the hot water and cold water mixing faucet with the casing rearranged left and right is installed in the reverse pipe of the other room, so that each room faces the other room. be.

(Function) A common hot water supply pipe and water supply pipe are buried in the wall that separates two rooms with common water facilities, so that one room has normal plumbing and the other has normal water supply pipes.
When installing hot water mixer faucets of the same structure on both piping in other rooms, which are reverse piping, it can be installed by simply turning the casing of the hot water mixer faucet on the reverse piping side left and right and joining them together. .

(Effects) Since the present invention is configured as described above, it has the following advantages.

(1) The thermostatic valve structure is housed in a casing, and this casing is installed inside the hot water mixer faucet so that it can be inserted and removed from either the left or right side, so it is possible to use common water in hotels, condominiums, or apartments. If hot water piping for each room is buried in a wall that partitions adjacent rooms with equipment, and the hot water and water piping is shared and the left and right piping is different for each room, the hot water and water piping can be installed in the forward and reverse directions. By simply changing the orientation of the casing to the left or right according to the situation, a hot water/cold water mixing faucet of the same structure can be easily installed regardless of the orientation of the piping.

(2) Due to the structural flexibility of the hot water mixer faucet, in which the casing housing the thermostatic valve structure can be swapped between left and right in the socket, hot water piping buried within the wall can be shared between both rooms. In addition, it is possible to reliably prevent the risk of having to redo the construction due to incorrect piping or releasing hot water from the water side.
