  • Patent number: 8534318
    Abstract: To provide a water spouting device capable of switching between spouting and stopping, flow volume adjustment, and spouted water temperature adjustment with a single operating portion. The present invention is a water faucet device (1) furnished with a flow volume adjustment function and a temperature adjustment function, including: an operating portion (6) capable of being pressed and rotated by a user; and flow volume/temperature adjustment means (10), whereby in a stopped water state, spouting is commenced when the operating portion of this flow volume/temperature adjustment means is pressed; in a spouting state, spouted water flow volume is changed when the operating portion is pressed continuously for a predetermined long-press determining time; and water flow is stopped when pressing of the operating portion ceases in less than the long-press determining time.

  • Publication number: 20110005619
    Abstract: To provide a water faucet device capable of easy grasp of setting states, without enlarging the size of the display portion. The present invention is a water faucet device (1) furnished with a flow setting function or temperature setting function; whereby the water faucet device has an operating portion (6) for controlling the water faucet device; a spout portion (2) forming a water discharge port; a light injecting portion (42), disposed at the base of the spout portion or the operating portion so as to be adjacent to the attaching surface at which the spout portion or the control portion are attached, for shining light onto the attaching surface; and display means (26) for displaying flow setting values or temperature setting values by varying the illumination range (46) formed on the attaching surface by the light illuminated from the light injecting portion.

  • Patent number: 7537175
    Abstract: Disclosed is a showerhead (1) capable of preventing damages in major or peripheral components and water leakage even if it is increased in size. The showerhead comprises a lower plate (2) formed with a plurality of discharging holes (2c) for discharging shower water therethrough, an upper plate (4) connected to the lower plate and formed with a water inlet port (4c), and a channel-defining member (6) disposed between the lower and upper plates to define an effective channel (6c, 6d) for allowing hot water entered between the lower and upper plates from the water inlet port to be led to each of the discharging holes, and an ineffective channel, so as to reduce a pressure-receiving area of the lower or upper plate to be subjected to a water pressure.
