Abstract
The invention provides a water heater with a water saving system. A control unit is connected to a water outlet selection switch, so that when a user begins to use the water in the water heater, the control unit firstly sends a first selection signal to the water outlet selection switch and then the water flowing out of the water storage cylinder of the water heater enters an additional water storage unit through a water outlet pipe and a second additional water pipe; and after a preset time span, the control unit sends a second selection signal to the water outlet selection switch and then the water flowing out of the water storage cylinder of the water heater flows out of the water heater through the water outlet pipe. The control unit is also connected to the additional water storage unit and a water inlet selection switch; when the water is fed into the water heater, the control unit detects whether water exists in the additional water storage unit; and if so, the control unit sends a third selection signal to the water inlet selection switch, so that the additional water storage unit is allowed to enter the water storage cylinder of the water heater. The water heater with the water saving system has the advantage that the cold water inside a water flow pipeline between the installation position of the water storage cylinder of the water heater and a water outlet can be prevented from being wasted.
Description
Technical field
The present invention relates to household appliance technical field, more particularly, the present invention relates to a kind of water heater with water-saving system.
Background technology
Water heater just refers to by various physical principles, cold water temperature is raise become a kind of electrical Household appliance of hot water.Different according to principle, water heater can be divided into electric heater, gas heater, solar water heater, fast magnetic domestic hot-water device etc.
Water heater is by utilizing electric energy, combustion gas, solar energy or electromagnetic energy homenergic that the heating unit that water heats is heated the water in the water heater water storage barrel.After this, when needs use hot water, open the light and to use hot water via the heating unit heating by regulating hot water.
But, when reality is used water heater, have such problem.Namely, because the installation site of water heater water storage barrel is far from the position of the delivery port that uses hot water, for example the water heater water storage barrel of solar water heater may be arranged in the roof, use the delivery port (for example tap in the shower head in the bathroom or kitchen) of hot water then to be positioned within doors, thereby so that when opening delivery port and use the hot water that the heating unit via water heater heated, need to through after a while so that the cold water in the water pipe between the installation site of water heater water storage barrel to the position of delivery port flows to end, just can obtain expecting the hot water that obtains.
When above-mentioned situation occurs, obviously, cold water in the water pipe if leave between the installation site of water heater water storage barrel to the position of delivery port flows out in vain, and do not take any measure, then can waste water resource, especially when the water pipe between installation site to the position of delivery port of water heater water storage barrel is very long (for example situation of solar water heater), can waste a large amount of water resources, and the number of times that water heater is used is more, and the water resource of waste is just more.
Therefore, hope can provide the technical scheme of the cold water in the water pipe between a kind of installation site to the position of delivery port of the water heater water storage barrel of avoiding waste.
Summary of the invention
