Water-saving assistant water tank device applicable to water heater

Abstract

The invention relates to a water-saving assistant water tank device applicable to a water heater. The water-saving assistant water tank device applicable to the water heater comprises the water heater, a tap water pipe, a mixing shower valve and a water-saving assistant water tank system, wherein the water-saving assistant water tank system comprises an assistant water tank, a float valve device, a check valve, a jet valve and a stop valve which are arranged and assembled together according to a certain sequence; a water inlet of the assistant water tank is connected to a hot water inlet of the mixing shower valve through the stop valve, namely at the tail end of a hot water outlet pipeline of the water heater; a water outlet of the assistant water tank is connected with a water suction port of the jet valve through the check valve; the float valve device is arranged above the water outlet inside the assistant water tank; the water outlet of the assistant water tank is opened and closed along with the water level; a water inlet of the jet valve is connected with the tap water pipe; a water outlet of the jet valve is connected with a cold water inlet of the mixing shower valve; and the mixing shower valve can also be replaced by a cold water and hot water jetting and mixing valve and can stabilize the temperature of outlet water. The water-saving assistant water tank device applicable to the water heater can recycle cold water prestored in the pipeline, so that water waste is reduced.

Description

technical field [0001] The invention relates to a water-saving auxiliary water tank device used in water heaters, which is suitable for water-saving of various pressure-bearing water heaters. Background technique [0002] Before present various pressurized water heaters are used for bathing, the water remaining in the pipeline between the water heater and the hot and cold water mixed shower valve after the last use is all cold water, especially when this pipeline is relatively cold. For a long time, it will bring waste and inconvenience. Previously, forced circulation with a booster pump would not only cause noise but also consume electricity, so it was not suitable. Contents of the invention [0003] The present invention provides a simple water-saving auxiliary water tank device for reusing the cold water remaining in the pipeline between the water heater and the hot and cold water mixing shower valve, which can save water. [0004] A water-saving auxiliary water tank ...
