Description

201043183 VI. Description of the Invention: [Technical Field] The present invention relates to a water discharge device, and more particularly to a device that can be particularly used in a shower device for recovering cold water in a pipeline. A water discharge device for recycling. [Prior Art] At present, many water outlet devices, especially the water outlet devices in shower devices, can usually adjust the hot and cold water mixing valve individually according to the climate temperature or the shower, through traditional manual operation or electronic pressing control. The cold water and hot water supplied to the mixing valve of the hot and cold water can be mixed with each other in an appropriate ratio to reach the shower temperature required by the user, and then passed through a jet jet (Handed Jet) and a hand-held shower head (Handheld).

Showerhead) and head-top showerheads (〇verhead Showerhead) and other water-discharging components are used to provide showers. However, before the above shower, the water turbulent flow line from the heater to the mixing valve between the hot and cold water will usually accumulate the hot water left over from the last shower, since these hot waters only need to be used for a period of time. Ten minutes or a few hours, it will naturally cool down and turn into cold water, because therefore, when the user turns on the hot and cold water again

4 201043183 It is a pity to be drained, so it is a pity; especially when the hot water supply line between the heater and the hot and cold water mixing valve is longer, the more water is wasted, the concept and trend of energy saving and environmental protection are emphasized.
