Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In order to facilitate understanding of the description, the same components are designated by the same reference numerals as much as possible in each drawing, and duplicate description is omitted.

As shown in FIGS. 1 and 2, the hot water mixing faucet 1 according to the embodiment of the present invention discharges hot water whose flow rate and temperature are adjusted by operating the mixing switching unit 12 provided in the main body 10. It has a water purification function that can stop water from being discharged from the water discharge unit of the above and further can stop water from being discharged from the water discharge unit by operating the water purification switching unit 14. Further, the hot water mixing faucet 1 mainly contains a water supply pipe 4 for supplying water (raw water) from a water supply source (not shown) to the main body 10 and heated hot water supplied from the hot water supply source (not shown). A hot water supply pipe 5 leading to 10 is provided.

The hot and cold water mixing faucet 1 is arranged on a counter such as a kitchen sink or a wash basin, and has a main body portion 10 extending to the left and right, and a mixing switching portion 12 and a water purification switching portion are formed at the left and right ends thereof. 14 is provided.

A so-called single lever cartridge is built in the mixing switching unit 12, and by moving the mixing switching unit 12 in the horizontal direction to open it, it is possible to switch the water discharge from the water discharge head unit 2 and adjust the flow rate. It is possible. Further, by rotating the mixing switching unit 12 in a vertical plane, it is possible to adjust the mixing ratio of hot water and water and adjust the water discharge temperature.

A so-called cylinder valve is built in the water purification switching unit 14, and it is possible to stop the discharge of purified water and adjust the flow rate by rotating the water purification unit 14.

Next, the water discharge head portion 8 is detachably attached to the water discharge head attachment portion that projects forward and diagonally upward from the front surface of the faucet device 1. The user can grasp the water discharge head portion 2 and remove it from the water discharge head attachment portion 22 of the faucet device main body 1 and pull it out to the front side for use.

A schematic diagram of the flow path of the hot water mixing faucet 1 is shown in FIG. The water supply pipe 4 connected to the water supply source (not shown) and the hot water supply pipe 5 connected to the hot water supply source (not shown) are connected to the main body 10, respectively. The water that has flowed into the main body 10 through the water supply pipe 4 branches inside the main body 10 and flows into the mixing switching unit 12 and the water purification switching unit 14, respectively. Further, the hot water that has flowed into the main body 10 through the hot water supply pipe 5 flows into the mixing switching unit 12. In the mixing switching unit 12, hot water is mixed and discharged to the hot water outflow pipe 6, and finally water is discharged from the water discharge head unit 2.

On the other hand, the water that branches inside the main body 10 and reaches the water purification switching unit 14 is sent to the water purification cartridge 16 installed inside the cabinet when the water purification switching unit 14 is opened. The purified water filtered by the water purification cartridge 16 merges with the hot water outflow pipe 6, and finally the water is discharged from the water discharge head portion 2.

FIG. 4 shows a view of the hot water mixing faucet 1 from below. As can be understood from the schematic diagram of FIG. 3, it is necessary to connect four pipes, a water supply pipe 4, a hot water supply pipe 5, a hot water outflow pipe 6, and a water purification flow path pipe 7, to the main body 10. The connection positions are shifted in the plane direction, respectively.

A method (manufacturing method) for connecting each pipe to the main body 10 will be described. First, each pipe 4, 5 and 6 is provided with flange portions 42, 52 and 62 at its ends. Further, the connecting member 8 connecting the pipes 4, 5, 6 and 7 is composed of the lower connecting member 82 and the upper connecting member 84, and the pipes 4, 5, 6 and 7 are inserted into the lower connecting member 82. It is provided with insertion grooves 43, 53, 63. The pipes 4, 5, 6 and 7 are inserted into the insertion grooves 43, 53 and 63 from the horizontal direction so that the flange portions 42, 52 and 62 are placed on the lower connecting member 82 (FIG. 5). In this state, the upper connecting member 84 is inserted from above each of the pipes 4, 5, 6 and 7 (FIG. 6). The upper connecting member 84 is provided with insertion holes 44, 54, 64, 74 at positions corresponding to the ends of the pipes 4, 5, 6, and 7, respectively, by inserting the ends of the pipes. , The horizontal movement of each of the pipes 4, 5, 6 and 7 is restricted (Fig. 7). In this state, the lower connecting member 82 and the upper connecting member 84 are fastened with screws to form an integrated connecting member 8. As a result, the movement of each of the pipes 4, 5, 6 and 7 in the axial direction is also restricted.

Next, the pipes 4, 5, 6 and 7 are connected to the main body 10 while being connected by the connecting member 8. As a result, each of the pipes 4, 5, 6 and 7 is easily connected to the water connection portion 46, the hot water connection portion 56, the hot water connection portion 66, and the purified water connection portion 76 to which each pipe is to be connected.

The hot water outflow pipe 6 is connected to the flexible hose 68. The connecting member 8 is provided with a flexible hose through hole 69 for inserting the flexible hose 68, and is configured to be slidable.

After connecting the pipes 4, 5, 6 and 7 to the main body 10, the pedestal 18 is attached from below. The pedestal 18 is provided with holes through which the pipes 4, 5, 6 and 7 pass. Further, the pedestal 18 includes a pipe cover 182 in which a part thereof is raised, and this portion is inserted into the flexible hose through hole 69 of the connecting member. The pipe cover 182 is provided to isolate the flexible hose 68 from the pipes 4, 5, 6 and 7, and the sliding of the flexible hose 68 causes the pipes 4, 5, 6 and 7 to wear. It plays a role in preventing.
