Description

[Technical Field]

[0001] The present invention relates to a faucet, and more particularly to a faucet that can discharge both normal water and electrolyzed water through the same water outlet pipe, thereby greatly simplifying the structure, reducing the volume, and effectively improving practicality. [Background technology]

[0002] Rapid industrial development in recent years has caused serious pollution of the air, land, and water sources, so people who are concerned about their health and hygiene have begun to drink purified or pure tap water by filtering it. In recent years, with the aim of improving health, reverse osmosis water, electrolyzed water, calcium ionized water, hydrogen water, reduced water, and other waters have appeared, claiming various effects on the human body. Electrolyzed water generators are known that electrolyze water to produce reduced electrolyzed hydrogen water, in which hydrogen molecules are dissolved. Electrolyzed hydrogen water has attracted attention as it is suitable for removing active oxygen. Currently, electrolyzed water generators installed under countertops typically have a water distribution pipe connected to a water source (or filtered water source), and the electrolyzed water generator is connected to a countertop faucet via a water guide pipe. Countertop electrolyzed water generators produce alkaline electrolyzed water and also discharge acidic water. Because this acidic water has sterilizing properties, some users store this acidic water and use it for hand washing, washing vegetables and fruits, and washing dishes.

[0003] However, the faucet of the electrolyzed water generator can usually only be used to dispense alkaline electrolyzed water and cannot simultaneously dispense water from a general water source, necessitating the installation of a separate faucet on the countertop (see Patent Document 1). The different water discharge patterns on the table not only take up space but also detract from the aesthetics of the overall countertop layout. The acidic water from the electrolyzed water generator is directly connected to the sink drain pipe, making it inconvenient to use. Currently, some manufacturers connect the water inlet pipe of the water source to the faucet of the electrolyzed water generator, but this is still a separate process, resulting in a complex structure, increased manufacturing difficulty and cost, and potentially unseen problems. Furthermore, the volume of such a faucet increases, significantly reducing its practicality. [Prior art documents] [Patent documents]

[0018] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0019] In the particular embodiment of the faucet of the present invention and its components shown in the accompanying drawings, all references to front and back, left and right, up and down, upper and lower, and horizontal and vertical are provided for convenience of this description and are not intended to limit the invention or its components to any position or spatial orientation. The dimensions specified in the drawings and specification may be changed according to the design and needs of the invention without departing from the patentable scope of the invention.

[0020] As shown in Figures 1 and 2, a faucet 100 according to one embodiment of the present invention is applicable to a common water outlet between a water treatment device 200 (e.g., an electrolyzed water generating device) and an inflow water source 300 (a general water source or a filtration device).

[0021] 2 to 5, the faucet 100 has a flange seat 20 installed inside a cylinder 10, and the top end of the cylinder 10 is inserted into a water outlet pipe 15 connected to the flange seat 20 via a fixing base 30. The cylinder 10 has a water outlet selection switch 16 connected to an external control unit, allowing the user to select between regular water or electrolyzed water. The water outlet selection switch 16 can be a touch sensor switch, a manual selector switch, an infrared induction switch, or the like.

[0022] The flange seat 20 is connected to a water inlet pipe 40 connected to the inflow water source 300, a water diversion pipe 50 connected to the water supply inlet of the water treatment device 200, and a water guide pipe 60 connected to the water outlet of the water treatment device 200. The flange seat 20 has a water supply passage 21 connected to the water inlet pipe 40, and further has a water diversion passage 22 connected to the water diversion pipe 50. The flange seat 20 also has a water guide passage 23 connected to the water guide pipe 60, and a water outlet passage 25 connected to the water outlet pipe 15. The water outlet passage 25 of the flange seat 20 communicates with the water diversion passage 22 and with the water supply passage 21 via a water supply manifold 26. A water supply switching valve 28 is provided between the water supply manifold 26 and the water outlet passage 25 / diversion passage 22. The water supply switching valve 28 allows selection between communication between the water supply manifold 26 and the water outlet passage 25 or communication between the water supply manifold 26 and the water distribution passage 22. Furthermore, the water outlet passage 25 of the flange seat 20 communicates with the water guide passage 23 via the water guide manifold 27 between the water supply switching valve 28 and the water outlet pipe 15. A water outlet switching valve 29 is provided between the water guide manifold 27 and the water guide passage 23. The water outlet switching valve 29 allows selection between communication between the water guide passage 23 and the water guide manifold 27. A solenoid valve 80 operated by the water outlet selection switch 16 is provided on the flange seat 20. The solenoid valve 80 can operate a valve 85 to selectively cut off the water supply from the water supply passage 21.

[0023] According to one embodiment, the faucet 100 is used in a water treatment device 200 (e.g., an electrolyzed water generator) that generates wastewater after treatment. The faucet 100 has a discharge pipe 18 that communicates with a flange seat 20 inserted around the periphery of the cylinder 10. The flange seat 20 has a drain pipe 70 that connects to the outlet of the water treatment device 200. The flange seat 20 also has a drain passage 24 that connects to the drain pipe 70. The other end of the drain passage 24 is connected to the discharge pipe 18, which allows the wastewater from the water treatment device 200 to be discharged. As shown in FIG. 8 , the water treatment device 200 discharges the generated acidic water and wastewater directly into a drain via the drain pipe 70.

[0024] 4 and 5, the water supply switching valve 28 and the water outflow switching valve 29 are composed of valve cylinders 281, 291. The valve cylinders 281, 291 have water guide grooves 282, 292 that connect the periphery to the end, and operation holes 283, 293 are provided at the end facing outward of the valve cylinders 281, 291, allowing the valve cylinders 281, 291 to be rotated using a tool. Leak-proof gaskets 284, 294 are provided on the periphery of the valve cylinders 281, 291, away from the water guide grooves 282, 292, improving the leak-proof effect.

[0025] This allows the selection of whether a common water source will flow directly or after treatment by designing the water supply passage 21, water branch passage 22, water guide passage 23, and water outflow passage 25 at the flange seat 20 and switching between the water supply switching valve 28 and the water outflow switching valve 29. This makes it possible to create a faucet that can be used in common applications and has a simple structure.

[0026] When the faucet of the present invention is actually operated, as shown in Figures 1, 6 and 7, when the faucet 100 is applied to the water treatment device 200 of the electrolytic water generating device, the water inlet pipe 40 of the faucet 100 is connected to the water outlet of the inflow water source 300 of the filtration device, the water distribution pipe 50 of the faucet 100 is connected to the water supply inlet of the water treatment device 200, and the water guide pipe 60 of the faucet 100 is connected to the water outlet of the water treatment device 200, and the drain pipe 70 of the faucet 100 is connected to the wastewater outlet of the water treatment device 200.

[0027] In operation, when drinking water from a regular water source or a filtered water source, as shown in Figure 6, by rotating the water supply switching valve 28 of the faucet 100 with a hand tool, the water supply manifold 26 connected to the water inlet pipe 40 is connected to the water outlet passage 25 connected to the water outlet pipe 15, and the water supply manifold 26 and the water branch passage 22 connecting the water branch pipe 50 are blocked. At the same time, by rotating the water outlet switching valve 29 of the faucet 100 with a hand tool, the water guide passage 23 of the water guide pipe 60 connected to the water treatment device 200 is blocked from the water guide manifold 27 connecting the water outlet pipe 15. When not activated, the solenoid valve 80 on the flange seat 20 operates the valve 85 to block the water supply from the water supply passage 21. When the user presses the water outflow selection switch 16 on the faucet 100, the solenoid valve 80 on the flange seat 20 activates the valve 85 to open the water supply passage 21, so that the water source from the water inlet pipe 40 flows directly through the water supply passage 21, the water supply manifold 26, and the water outflow passage 25, and then flows out of the water outflow pipe 15, which the user can drink. At the same time, the water supply switching valve 28 and the water outflow switching valve 29 can prevent the water source from flowing into the water treatment device 200 via the water distribution passage 22 or the water guide passage 23.

[0028] When drinking water treated by a water treatment device 200 (e.g., an electrolytic water generator), as shown in Figure 7, first, by using a hand tool to turn the water supply switching valve 28 on the faucet 100, the water supply manifold 26 connected to the water inlet pipe 40 and the water branch passage 22 connected to the water branch pipe 50 are connected to each other, while the water supply manifold 26 and the water outlet passage 25 are blocked. By using a hand tool to turn the water outlet switching valve 29 on the faucet 100, the water guide passage 23 on the water guide pipe 60 connected to the water treatment device 200 are connected to the water guide manifold 27 connected to the water outlet pipe 15. When not activated, the solenoid valve 80 on the flange seat 20 operates the valve 85 to block the water supply from the water supply passage 21. When a user presses the water outflow selection switch 16 on the faucet 100, the solenoid valve 80 on the flange seat 20 activates the valve 85 to open the water supply passage 21, allowing the water source from the water inlet pipe 40 to flow directly through the water supply passage 21, the water supply manifold 26, and the water diversion passage 22, and then through the water diversion pipe 50 into the water treatment device 200, thereby treating the water source (e.g., electrolyzed water). The water supply switching valve 28 prevents the water source from being discharged through the water outflow passage 25 and the water outflow pipe 15. After the water treatment device 200 treats the water source, the treated water flows from the water guide pipe 60 into the faucet 100, passes through the water guide passage 23 on the flange seat 20, the water guide manifold 27, and the water outflow passage 25, and then flows out of the water outflow pipe 15, allowing the user to drink the treated water (e.g., electrolyzed water). The wastewater generated during the process of treatment by the water treatment device 200 flows from the drain pipe 70 through the drain passage 24 of the flange seat 20 and then out the discharge pipe 18, allowing users to use this water for washing their hands or vegetables, etc.

[0029] From the above explanation, the faucet 100 of the present invention can select whether ordinary water source flows directly, treated and filtered water flows, or electrolyzed water flows, by combining the design of the water supply passage 21, water branch passage 22, water guide passage 23, and water outflow passage 25 at the flange seat 20 with the switching of the water supply switching valve 28 and the water outflow switching valve 29. This allows the same water outflow pipe 15 to be shared for all water flows, greatly simplifying the structure, effectively reducing the volume, and effectively improving its practicality.

[0030] In one embodiment, as shown in FIG. 9, the faucet 100 of the present invention may directly dispense a single type of water without switching between tap water, filtered water, or electrolyzed water. Its main feature is that a solenoid valve 80 for controlling the water flow is mounted on the flange seat 20 and inside the cylinder 10. Therefore, when installing the faucet 100 of the present invention, simply place it in a suitable location on the kitchen counter and connect the water channels one by one. This achieves the purpose and effect of enabling quick and easy access. During use, tap water or filtered water flows directly into the water inlet pipe 40, passes through the water supply passage 21 and the water supply branch 26, and then flows directly out of the water outlet pipe 15. The solenoid valve can selectively shut off the water supply from the water inlet pipe by operating a valve.

[0031] In one embodiment, as shown in FIG. 10 , the faucet 100 of the present invention may directly dispense a single type of water without switching between two water sources. For example, tap water or filtered water may be directly fed into the flange seat 20, and the treated liquid flows out through the flange seat. A key feature of this configuration is that the solenoid valve 80 for controlling the water flow is also provided on the flange seat 20 and inside the cylinder 10. Therefore, when installing the faucet 100 of the present invention, the user simply places the faucet 100 in a suitable location on the kitchen counter and connects the water channels one by one. This achieves the objective and effect of enabling quick and easy access. Specifically, during use, tap water flows into the water treatment device through the water inlet pipe 40, the water supply passage 21, the water supply branch 26, the water distribution passage 22, and the water distribution pipe 50 in this order. The treated liquid then flows through the water guide pipe 60, the water guide passage 23, the water guide branch 27, and the water outlet passage 25, and finally flows out of the water outlet pipe. The solenoid valve 80 selectively shuts off the water supply to the water inlet pipe by actuating a valve 85. The solenoid valve 80 may be mounted on the flange seat 20 and housed inside the cylinder 10, allowing quick and easy access for the user.

[0032] 11 and 12, a water inlet filter 41 is provided on the water inlet pipe, and the water inlet filter 41 can be provided at the water outlet end of the water inlet pipe 40, or the water inlet pipe 40 can be provided in the flow path of the water outlet pipe. This effectively filters out coarse impurities to prevent clogging of the water passage in the flange seat 20, and the valve 85 of the solenoid valve 80 effectively blocks the water passage, improving the water blocking effect.
