Referring to these drawings, the functional faucet 100 according to the present embodiment allows the position of the sensor to allow water discharge to be variable through the rotational sensor ring 130, unlike the prior art, so that the convenience of use is far superior to that of the prior art. allow it to rise

The functional faucet 100 according to the present embodiment capable of providing such an effect includes a faucet body 110, a shank 120, a SHANK, a rotary sensor ring 130, and a sensor window 140. and a sensor PCB 150 (SENSOR PCB).

The faucet body 110 is an external structure of the functional faucet 100 according to the present embodiment. The following structures and components including the shank 120, the rotational sensor ring 130, the sensor window 140, and the sensor PCB 150 are mounted on the faucet body 110 by position.

A water discharge unit 111 through which water is discharged is provided at one end of the receiving body 110 . And, a lever 112 for discharging or stopping the discharging of water is provided on the side of the receiving body 110 . The functional faucet 100 according to the present embodiment is a side lever 112 type faucet.

A fixing structure 114 is provided at the lower portion of the receiving body 110 to be disposed and fixed to the lower portion of the sink bowl. The fixing structure 114 is coupled to the shank 120 at the bottom of the sink bowl so that the receiving body 110 is firmly supported by the sink bowl.

As shown in FIG. 4, the fixing structure 114 is composed of an upper fixing part 114a and a lower fixing part 114b. First, the upper fixing part 114a is supported against the lower surface of the sink bowl, and then the upper fixing part (114a) When the lower fixing part 114b is inserted into the bottom and rotated, the female screw part formed on the inner circumferential surface of the lower fixing part 114b and the male screw part formed on the outer circumferential surface of the shank 120 are engaged.
At this time, the upper end of the shank 120 is supported by the faucet body 110, the middle part of the shank 120 presses the sensing guide 160 on the upper surface of the sink bowl, and the lower end of the shank 120 is the lower fixing part 114b. Since the upper fixing part 114b is pressed against the lower surface of the sink ball when it is engaged and tightened,
The faucet body 110, the shank 120, the sensing guide 160, and the fixed structure 114 are firmly coupled to the sink ball, and when coupled in this way, the rotational sensing ring 130 has a gap and the fixed structure Since the fixing force by 114 is not transmitted and the O-ring exists between the sensing guide 160 and the smooth rotation is possible.

That is, since the part for fixing the functional faucet 100 is limited to the sensing guide 160, the fixing force by the fixing structure 114 can be prevented from being transmitted to the shank 120 and the rotational sensor ring 130. . Accordingly, smooth rotational motion of the rotational sensing ring 130 can be obtained. The fixing structure 114 may include an upper fixing part 114a fixed to the shank 120 and a lower fixing part 114b connected to the upper fixing part 114a.

The shank 120 is a structure fixed to the lower portion of the receiving body 110 . An upper portion of the shank 120 is disposed above the sink bowl and a lower portion is disposed below the sink bowl.

The shank 120 is a pipe-shaped structure having different diameters along the length direction. A large-area wire passage hole 121 is formed in the shank 120 .

That is, since the sensor PCB 150 is applied to the functional faucet 100 according to the present embodiment, a wire 151 (WIRE) is used to supply power to the sensor PCB 150. A large-area wire passage hole 121 is formed in the shank 120 so that the wire 151 is not constrained such as being twisted or shorted even when a rotating operation is performed.

In other words, the large-area wire passage hole 121 formed in the shank 120 is such that the wire 151 electrically connected to the sensor PCB 150 is not constrained even when the rotary sensor ring 130 rotates. ), which is a means for securing the passage of, which is formed in a large area. Therefore, even if an operation of rotating the rotary sensor ring 130 is performed, the wire 151 is not constrained such as being twisted or shorted.

In this embodiment, the large-area wire passage hole 121 formed in the shank 120 has an elliptical structure extending through one side of the shank 120 .

However, as shown in FIG. 9 showing modifications, the large area wire passage hole 221 of the shank 220 may be a large circular hole, or as shown in FIG. 10, the large area wire passage hole 321 of the shank 320 ) is a square hole but may be disposed on both sides, and as shown in FIG. 11, the large area wire passage hole 421 of the shank 420 is an elliptical hole but may be disposed on both sides. Although any hole shown in FIGS. 9 to 11 can provide the effect of the present invention, it is advantageous to make it as large as possible. The holes shown in FIGS. 9 to 11 may be implemented by a mold or mechanical post-processing.

And, a wire guide 152 (WIRE GUIDE) for guiding the wire 151 is provided in the shank 120. The wire guide 152 may be a separate plastic structure, for example, a pipe-shaped plastic structure, or may be a simple coating.

The rotational sensing ring 130 is a means for rotating the sensor PCB 150 and is rotatably coupled to the shank 120 . A through hole 131 is formed in the rotational sensor ring 130 . The sensor window 140 is coupled to the through hole 131 .

A sensing guide 160 is applied for rotatable coupling of the rotational sensing ring 130 . The sensing guide 160 is coupled to the lower end of the shank 120 but serves to guide the rotational motion of the rotary sensor ring 130 .

A rotation angle limiting stopper 161 for limiting the rotation angle of the rotational sensor ring 130 is protruded from the sensing guide 160 .

The rotational angle range of the rotary sensor ring 130 due to the action of the rotational angle limiting stopper 161 may be, for example, within 180 degrees. to rule out the possibility.

The sensor window 140 is coupled to the through hole 131 area of the rotational sensor ring 130, but forms one body with the rotational sensor ring 130. Accordingly, when the rotary sensor ring 130 is rotated, the sensor window 140 also rotates.

An O-ring is interposed between the sensor window 140 and the sensing guide 160 . Accordingly, smooth rotational motion of the rotational sensing ring 130 can be obtained.

The sensor PCB 150 is an electronic component in which a sensor (SENSOR, not shown) for detecting an approach signal is embedded and connected to the rear of the sensor window 140. When approaching the sensor PCB 150, water is ejected without operating the lever 112.

The sensor PCB 150 and the sensor window 140 form one body. Accordingly, when the rotary sensor ring 130 is rotated, the sensor PCB 150 in addition to the sensor window 140 also rotates together.

At least one side of the sensor window 140 and the sensor PCB 150 is provided with a sensor guide 155 (SENSOR GUIDE) for guiding a sensing action of a sensor mounted on the sensor PCB 150 . The sensor guide 155 may be a kind of plastic tunnel structure.

As described above, in the case of the present embodiment, the sensor PCB 150 including the sensor can be rotated by the action of the rotational sensing ring 130, so that it can be used according to the usage pattern of the consumer. For example, since the sensor PCB 150 can be used after adjusting it according to the use patterns of consumers including left-handers and right-handers, convenience in use can be greatly increased.

According to the present embodiment, which operates based on the structure as described above, the position of the sensor for allowing the water to be discharged can be changed through rotational sensing unlike the prior art, so that the convenience of use can be greatly improved compared to the prior art. do.

Referring to this figure, the functional faucet 500 according to the present embodiment also includes a faucet body 510 having a water discharge unit 511 and a lever 512.

The functional faucet 500 according to the present embodiment is an upper lever 512 type faucet, and the rotary sensor ring 130 can be disposed at the same position and act even in this upper lever 512 type faucet.

Even if the present embodiment is applied, the convenience of use can be greatly improved compared to the prior art by allowing the position of the sensor to allow the discharge of water to be changed through the rotational sensor ring 130 unlike the prior art.
