The water discharge pipe 3 extends obliquely upward from the outer circumference of an outer cylinder 31 that rotatably fits in the middle part of the faucet body 1 and covers the concave grooves 14 and 15 in a watertight manner. As described above, it is integrally formed with the outer cylinder 31, and a raw water outflow passage 3a and a fresh water outflow passage 3b are vertically divided and formed therein.

In addition, at the tip of the water discharge pipe 3, an inner mounting port 81 in which the outlet portion of the fresh water discharge channel 3b is eccentric to the center of the water discharge channel 3 and the raw water discharge channel 3a so as to surround the outer periphery of the mounting port 81 are provided. Each of the outer mounting ports 82 is formed by expanding the outlet part of each of them, and further, the inner pipe 83, which communicates the inner part with the fresh water outflow passage 3b, is inserted into the inner mounting port 81, and the outer mounting port 82 is fitted into the outer mounting port 82. The outer pipe 84, which communicates the inside with the raw water outlet 3a, is inserted to form the inner-outer double pipe-shaped connecting pipe portion 8.

The water discharge head 5 is rotatably attached to the outer periphery of the connecting pipe portion 8, that is, the outer periphery of the outer pipe 84. The water discharge head 5 is formed by connecting a head body 5b to the tip of a tube portion 5a that is rotatably fitted onto the outer tube 84. The pipe portion 5a is equipped with a retaining screw 5c that engages with a groove recessed in the outer periphery of the outer pipe 84.

On the bottom surface of the head body 5b, a raw water spouting port 51 having a straightening discharge hole 51a opened in the center thereof and a plurality of foam side discharge holes 51b radially opened so as to surround the discharge hole 51a is formed. At the same time, a fresh water spout 52 is opened at an appropriate position on the bottom surface. A handle 5d is rotatably mounted on the upper surface of the head body 5b.

Inside the head body 5b, an annular fresh water flow path 53 that connects the inner pipe 83 and the fresh water discharge port 52, and a raw water flow path that connects the outer pipe 84 to the flow straightening discharge hole 51a and the foam discharge hole 51b. 54 is divided into sections.

In the raw water flow path 54, a partition wall 92 having an insertion hole 91 located directly above the flow straightening discharge hole 51a is provided, and an elevating cylinder 93 is vertically movably inserted into the hole 91, and the above-mentioned hole is formed. A screw member 94 that rotates integrally with the handle 5d is provided above 91, and the outer peripheral screw portion of this screw member is screwed onto the inner circumference of the raising and lowering cylinder 93, and the lifting cylinder 93 moves up and down by the turning operation of the handle 5d.

The raw water flowing into the elevating cylinder 93 through 96 becomes a swirl flow and is jetted so as to pass through the opening wall 95 and scatter outward, and the air sucked from the rectification discharge hole 51a by its negative pressure is taken in. Then, the foam is discharged from the foam discharge hole 51b in a foam state.

Further, a bush 97 that projects into the elevating cylinder 93 and reaches the vicinity of the opening of the opening wall 95 is continuously provided at the upper edge of the straightening discharge hole 51 a, and the lower end of the elevating cylinder 93 is provided around the bush 97. By providing an annular seat 98 that comes in contact with and separates from each other, it is possible to selectively switch the outflow direction of the raw water passing through the opening wall 95 to the foam discharge hole 51b side or the rectification discharge hole 51a side.

Hereinafter, a method of using the single-lever faucet of the present embodiment having the above-mentioned configuration will be described. When the faucet is not used, the movable disk 7 is located at a position where it blocks the communication between the long hole 71, the hot water inlet 61, and the water inlet 62. In this state, the water discharged from the raw water outlet 51 and the fresh water outlet 52 is not discharged. Not performed (see D in FIG. 2).

From this state, the operating handle 2 is vertically swung to slide the movable disk 7 so that the long hole 71 is located on the line connecting the hot water inlet 61, the water inlet 62, and the water purifier connecting port 63. At this time, if the long hole 71 communicates with both the hot water inlet 61 and the water inlet 62 and the communication hole 72 communicates with the raw water outlet 64 as shown in FIG. The mixed water of hot water from the hot water supply source H (that is, raw water) flows down the raw water outlet 64, the raw water side concave groove 14, and the raw water outflow passage 3a and flows into the raw water flow passage 54 of the head main body 5b.

Further, at this time, if the lower end of the elevating cylinder 93 is in contact with the seat 98 as shown in FIG. 1, the mixed water in the raw water flow path 54 passes through the inflow hole 96, the opening wall 95, and the bush 97, and is rectified. It is discharged from the discharge hole 51a in a straightened manner. Further, if the elevating cylinder 93 is moved up by operating the handle 5d and the lower end thereof is separated from the seat 98, the raw water in the raw water flow passage 54 will pass through the inflow hole 96 and the opening wall 95 and from the rectifying discharge hole 51a. The air is taken in and is discharged in a foam state from the foam discharge hole 51b. Therefore, raw water does not flow into the fresh water side discharge path (water discharge path), and there is no possibility that raw water-containing substances are contained in fresh water.

Further, in the mixed water discharge state shown in FIG. 2B, the opening degree of the hot water inlet 61 or the water inlet 62 is adjusted by rotating the operation handle 2 to the left and right to appropriately adjust the temperature of the mixed water. .. Further, from the same state, if only the hot water inlet 61 or the water inlet 62 is connected to the raw water outlet 64, hot water or water is discharged from the straightening discharge hole 51a or the foam discharge hole 51b.

When switching from the above-mentioned raw water discharge state to the fresh water discharge state, the operation handle 2 is turned in the direction of the water cleaner communication port 63 to open the elongated hole 71 of the water inlet 62 and the water cleaner communication port 63. Both are communicated with each other, and the communication between the communication hole 72 and the raw water outlet 64 is cut off (see FIG. 2B). At this time, the water from the water supply source C passes through the water purifier connection port 63 and the pipe 41a and flows into the water purifier 4, and the filtered fresh water flows through the pipe 42a, the fresh water side concave groove 15, and the fresh water outflow passage 3b. It flows down, flows into the fresh water flow path 53 of the head body 5b, and is discharged from the fresh water discharge port 52.

At the time of this switching operation, as shown in FIG. 2C, before the communication between the water inlet 62 and the raw water outlet 64 is interrupted, the water inlet 62 and the water purifier connecting port 63 communicate with each other, that is, the raw water. Since the fresh water discharge from the fresh water discharge port 52 starts before the water discharge from the water discharge port 51 is stopped, the change of the water discharge form can be performed visually. Similarly, when switching from the fresh water discharge state to the raw water discharge state, the water inlet 62 and the raw water outlet 64 are communicated with each other before the communication between the water inlet 62 and the water purifier communication port 63 is cut off, that is, Before the fresh water discharge from the fresh water discharge port 52 is stopped, the raw water discharge from the raw water discharge port 51 starts.

Further, in each of the above-mentioned discharge states, the movable handle 7 is slid by operating the operating handle 2 up and down to adjust the openings of the hot water inlet 61 and the water inlet 62 by the long holes 71, The flow rate of each spout is adjusted appropriately.

Further, in the above-described raw water discharge state or fresh water discharge state, the water discharge head 5 is rotated in the circumferential direction to adjust the positions of the raw water and fresh water discharge ports 51a, 51b, 52 as appropriate. The discharge direction (angle) of raw water and fresh water can be set arbitrarily (see Fig. 5).

In this embodiment, the raw water outflow passage 3a and the fresh water outflow passage 3b provided in the water discharge pipe 3 are formed by partition walls that divide the inside of the water discharge pipe 3 into upper and lower parts. It is also possible to form it by dividing partitions, and these are appropriately selected according to the convenience at the time of molding the water discharge pipe.

Further, in the present embodiment, as described above, water from the water supply source C, hot water from the hot water supply source H, mixed water of these hot and cold water, and fresh water filtered by the water purifier can be selectively discharged. Although the stopper has been described, the present invention is not limited to this. For example, in the above-described configuration, the hot water inflow path is not provided, and the water from the water supply source C and the fresh water filtered by the water purifier are selectively selected. It is also possible to use a faucet capable of discharging.

[0036]

[Effect of the device]

 Since the single-lever faucet that also serves as a water purifier according to the present invention is configured as described above, one of the raw water spout and the fresh water spout can be discharged from the other spout by rotating the operating handle to the left or right. When switching to a state in which the water discharge is performed, both the raw water discharge and the fresh water discharge are performed in the switching process, that is, the discharge of one water is stopped before the discharge of the other water is started, so that the change of the water discharge form is reliable. Can be seen visually.

Therefore, unlike the conventional product, in the process of switching the water discharge form by the left and right rotation operation of the operation handle, there is no possibility that the water is not discharged from the water discharge port, and the user mistakenly thinks that it is a failure. It is possible to eliminate the inconvenience of causing an incorrect operation such as inadvertent water discharge and greatly improve usability.
