Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to the installation of a hot and cold water mixing faucet among sanitary appliances that has a thermostatic valve structure inside and can be rearranged according to the direction of the piping, and the piping. It is related to.

(Prior art) Conventionally, when rooms of the same size are installed in hotels, condominiums, apartments, etc., when installing common facilities such as bathrooms and washrooms in adjacent rooms, hot water pipes are used. It is common practice to bury water supply pipes in advance within a common wall that partitions each room, and in this case, the arrangement of the hot water and water sides was as shown in Figure 5. .

To explain about Doi Figure 5, the hot water supply pipe 41 is the branch pipe 4.
2 from the chamber F side to the chamber F side, and the branch pipe 48 connects the chamber E.
The hot water supply tap part 441 of the mixer faucet G in the room F is connected to the hot water supply tap part 44'■ζ of the mixer faucet G' in the chamber F through the branch pipe 48', and the room F is connected to the branch pipe 42' of the water supply pipe 45. The branch pipe 46 of the mixing faucet G' is connected to the water supply tap part 47+ζ of the mixing faucet G', and the branch pipe 46' is connected to the chamber E.
The hot water supply pipe 41 is connected to the water supply tap part 47' of the mixing faucet G.
, a water supply pipe 45 and branch pipes 42 and 42' are installed in advance in a wall H common to chambers E and F.

In the above piping, the branch pipes for hot water and water are complicated, and the branch pipes intersect in a complicated manner, which not only takes time and effort to install, but also makes it easy to attach branch pipes incorrectly. There were a lot of them. Therefore, hot water may come out from the water side during a water flow test after piping, which often results in the inconvenience of having to rework the piping.

(Problem to be solved by the invention) The problem to be solved by this invention is that two rooms with common water facilities such as a bathroom or washroom are separated by a common wall. To enable a common hot water supply pipe and a water supply pipe buried in advance in a common hot water supply pipe and a forward and reverse piping, and one side of a hot water mixing faucet having the same structure to be attached to the reverse piping by simple rearrangement.

[Technical means for solving the problems] The technical means taken by the present invention to solve the above problems is to provide a common flow path for hot and cold water and a flow path for water and hot water valve inside the mixer faucet. Two straight mixing chambers are installed with both channels Cζ parallel and open at both ends, and this mixing chamber is divided into two with a rib in the middle so that it can be used for both hot water and cold water or water and hot water. In order to have two rooms, the fleas are divided by multiple ribs parallel to each other, and a common socket is provided in each rib, and this socket controls the temperature of the mixed water in response to the temperature of the hot water. A straight casing containing a valve structure with an automatic thermostat is configured to be able to be inserted and removed freely, and a rib and a bearing plug having an inner diameter common to the insertion port are provided at the outer ends of both mixing chambers. The mixing chamber and the two chambers are communicated through the inlet of the casing, and the mixing chamber and the discharge pipe and the pipe joint leading to the shower head are communicated through the outlet of the casing. The casing can be freely inserted into and removed from the socket, and a shared hot water pipe and a branch pipe communicating with the water supply pipe, which have been buried in advance inside a common wall of buildings where bathrooms or washrooms are installed next to each other, can be inserted into and removed from the socket. With both opening ends facing each adjacent chamber, the normally assembled pumping mixer faucet is attached to the front pipe of one chamber, and the hot water mixer faucet with the casing rearranged left and right is attached to the other reverse pipe. It has been cut down for installation.

(Function) A common hot water supply pipe and water supply pipe are buried in the wall that partitions two rooms with common water equipment, so that one room has normal piping and the other room has reverse piping, with the same structure. When installing a water pump mixer,
It can be installed by simply turning the casing of the pumping mixer faucet on the side of the back riser pipe to the left and right and joining it together.

(Example) Hereinafter, an example of the present invention will be described in detail based on the drawings.

In this embodiment, as shown in FIGS. 1 to 8, a single hot/cold water mixing faucet 1 has an internal Eζ common hot water flow channel 2 and a flow channel 8 disposed on substantially the same straight line. A plurality of mixing chambers 4.4a having the same shape are formed in parallel with 8, and the middle one of the mixing chambers 4.4a communicates with the chamber 5, which is also used for hot water and water, and the flow path S, which communicates with the flow path 2. Room 6 with shared hot water and water

However, another bearing plug 10a has a female serrating part 1 on the inner peripheral surface.
The nozzle grill 17 is connected to a handle 20 via a screw 19 to a separately provided handle shaft 13 for temperature adjustment.
The valve stem 14 and another handle 20' are removably attached to each other through a screw 191.

The valve structure 13 is straight and has the openings 8.8a, 8b.
The casing 21 has an outer diameter that can be inserted into and removed from the casing 21 and maintain a watertight connection between the sockets 8.8a and 8b. An inlet 22 for pumping water that communicates with the chamber 5, an inlet 28 that also communicates with the chamber 6, and an outlet 24 for mixed water that communicates with the mixing chamber 4a are provided. While the hot water introduced through the temperature sensor case 27 passes through the outlet 24 and flows into the mixing chamber 4a, the temperature sensor 28 operates in response to the temperature of the water, causing the valve body 26 to close. At the same time, the water valve seat 29 is displaced toward the hot water valve seat 25 side, and this action reduces the outflow of the cancer valve seat 25.
A thermostatic system that automatically supplies mixed water with an appropriate temperature fζ adjusted according to the ratio with the hot water by supplying the cold water introduced from the water valve seat 29 to the mixing chamber 4a through the same route as the hot water. Configure. Separately) Provided with r co-feeding pipe 30
and the water supply pipe 31 as shown in Fig. 3 (a) and (b).
Rooms A and B with common water facilities (bathtub, washroom)
The water supply pipe 30 and the water supply pipe 31 have branch pipes 32 and 3 installed at right angles to each other.

Restore the handle 20, 20' according to the sequence.

As described above, the inlet 22 of the casing 210 with the left and right sides reversed communicates with the flow path 3 leading to the water supply source and the same inlet 6, and the inlet 23 communicates with the flow path 2 leading to the water supply source and the inlet 5, At the same time, the outlet 24 corresponds to the side of the mixing chamber 4 that communicates with the discharge pipe or the pipe joint 37 leading to the shower head, so that the hot water flowing into the inlet 22 via the flow path 8 and the chamber 6 is directed to the valve body 22 in the manner described above. Then, while reaching the outlet 24 through the temperature sensitive body case 27, mixed water at an appropriate temperature is supplied while automatically controlling the temperature.

(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 can be used for common water facilities such as hotels, apartments, etc. If there is a wall fζ that partitions adjacent rooms, and if the hot water pipes for each room are buried, and the water pipes are shared and the left and right are different for each room, then fζ is the normal and opposite direction of the hot water. By simply changing the orientation of the casing to the left or right to match the piping, a hot water/cold water mixing faucet of the same structure can be easily installed regardless of the orientation of the piping.

(2) The structural flexibility of the pump mixer faucet, which houses the mostat-type valve structure and allows the casing to be inserted left and right into the socket and interchangeable, allows for pumping water piping buried within the wall. Not only can the rooms be shared, but both can be made simpler, and furthermore, it is possible to reliably prevent the risk of redoing construction due to incorrect piping or the risk of hot water being released from the water side.
