Water saving system for water heater

Abstract

The invention discloses a water saving system for a water heater. The water saving system comprises a water storage tank, a control cabinet, a temperature sensing element, a first electromagnetic valve, a second electromagnetic valve and a first negative pressure water suction mechanism. A first connecting position, a second connecting position and a third connecting position are sequentially arranged on a hot water pipe in the water outlet direction. The first negative pressure water suction mechanism is arranged on the first connecting position, and a negative pressure opening of the first negative pressure water suction mechanism is connected with the water storage tank through a first negative pressure pipe. The temperature sensing element is arranged at the second connecting position, the second connecting position leads a water storage pipe to the water storage tank, and the first electromagnetic valve is arranged on the water storage pipe. The second electromagnetic valve is arranged on the third connecting position, and the temperature sensing element, the first electromagnetic valve and the second electromagnetic valve are electrically connected with a control end of the control cabinet. The water saving system is simple in overall structure and high in automation degree, collected cold water automatically flows back to the hot water pipe to be output according to the negative pressure principle instead of being pumped back to the water heater, and the water saving system is suitable for water heaters of various existing types and is very easy and convenient to assemble and apply.

Description

technical field [0001] The invention relates to a water-saving system, in particular to a water-saving system for a water heater. Background technique [0002] Existing water heaters mainly include a water heater body, a cold water pipe and a hot water pipe. Connect the faucet body, the faucet body is connected to the water outlet mechanism such as the shower, the spout, etc., and the water outlet mechanism and water temperature adjustment can be realized by operating the faucet switch. When using the water heater, the hot water pipe connecting the water heater and the water outlet mechanism is filled with cold water, and this part of the cold water will be drained every time it is used, thus causing a waste of water resources. [0003] In order to solve the problem of wasting water resources by the water heater, there are some solutions in the prior art, among which the more common one is to set up a closed circuit together with the water heater, and return the cold water ...
