Description

This invention relates to a faucet system comprising a pair of adjacent faucet devices. A faucet system is known that includes a pair of adjacent faucet devices, specifically a faucet system comprising a hot and cold water mixing faucet and a disinfecting faucet (Patent Document 1). Furthermore, a touchless faucet device is known that combines a pair of first human body detection sensors with sensing areas directed to the left and right of the spout, and a second human body detection sensor with a sensing area directed downwards from the spout (Patent Document 2). Japanese Patent Publication No. 2017-169975Japanese Patent Publication No. 2012-127155 This is a schematic front view of a faucet system according to one embodiment of the present invention.Figure 1 is an explanatory diagram showing the first water discharge state (soft discharge) of the hot and cold water mixing faucet device.Figure 1 is an explanatory diagram showing the second water discharge state (water broom discharge) of the hot and cold water mixing faucet device.Figure 1 is an explanatory diagram of the pull-out function of a hot and cold water mixing faucet.This is a longitudinal cross-sectional view in the front-to-back direction near the raw water sensor case of the hot and cold water mixing faucet device shown in Figure 1.Figure 1 is a longitudinal cross-sectional view in the front-to-back direction near the disinfectant water sensor case of the disinfectant water faucet device.This is a vertical cross-sectional view in the left-right direction near the disinfectant water sensor case of the disinfectant water faucet device shown in Figure 1. Hereinafter, an embodiment of the present invention will be described with reference to the attached drawings. Figure 1 is a schematic front view of a faucet system 100 according to an embodiment of the present invention. The faucet system 100 of this embodiment comprises a hot and cold water mixing faucet device 1 (an example of a second faucet device) and a disinfecting faucet device 101 (an example of a faucet device). The hot and cold water mixing faucet device 1 and the disinfecting faucet device 101 are adjacent to each other in the left-right direction, facing each other from the front, with the hot and cold water mixing faucet device 1 positioned on the left and the disinfecting faucet device 101 positioned on the right. (Configuration of the hot and cold water mixing faucet device 1) The hot and cold water mixing faucet device 1 is a hot and cold water mixing faucet that can adjust the flow rate and temperature of the raw water, and is also a faucet that can select and use purified water instead of raw water (hot and cold water), and is positioned, for example, on the back side (rear side) of a kitchen sink. The lower wall of the kitchen sink is equipped with a hot water inlet 2, a cold water inlet 3, and a purified water inlet 61. The hot water inlet 2 is connected to the hot and cold water mixing valve 21 in the base end 10 of the hot and cold water mixing faucet device 1 via a hot water supply solenoid valve 52 and a hot water pipe 22. The cold water inlet 3 is connected to the same hot and cold water mixing valve 21 via a cold water supply solenoid valve 53 and a cold water pipe 23. The purified water inlet 61 is connected to the inlet of the purified water cartridge 63 via a purified water supply solenoid valve 54 and a purified water supply pipe 62. The hot and cold water mixing valve 21 is a known configuration and utilizes a single-lever cartridge to control (operate) the flow rate and temperature. Specifically, hot water is supplied via the hot water supply pipe 22, and cold water is supplied via the cold water supply pipe 23. After mixing to achieve the desired flow rate and temperature according to the position and orientation of the single-lever cartridge, the water is discharged via the outlet pipe 24 and the cold water supply hose 25. The water supply hose 25 is connected to the water outlet pipe 24 and its movement in the space below the kitchen sink is restricted by passing through a hose spacer guide 26 fixed to the water outlet pipe 24. Furthermore, a stopper 27 is attached to the water supply hose 25 below the hose spacer guide 26, limiting the amount the water supply hose 25 can be extended. A raw water/purified water branching fitting 65 is provided at the connection point between the water outlet pipe 24 and the water supply hose 25, and is connected to the water outlet of the purified water cartridge 63 via the purified water outlet pipe 64. The spout of the hot and cold water mixing faucet device 1 of this embodiment comprises a roughly cross-shaped base end portion 10 having a right-side (one-sided) projection and a left-side (other-sided) projection; a flow control and temperature control lever 20 (an example of a flow control control unit) provided on the right-side (one-sided) side of the right-side (one-sided) projection of the base end portion 10; and a rotat
