Water-saving intelligent hot water regulator and control method thereof

Abstract

The invention provides a water-saving intelligent hot water regulator and its control method. The installation box of the regulator is provided with a hot water nozzle, a cold water nozzle, a water outlet nozzle and a control circuit interface. The pressure pump is connected to the water inlet pipe of the three-way valve, the first water outlet of the three-way valve is connected to the cold water pipe through the one-way valve, and the second water outlet of the three-way valve is connected to the mixing chamber. The return pipe of the pressure pump is provided with a return flow regulating valve, and the cold water pipe port is also connected to the mixing chamber through the cold water flow regulating valve. The water temperature detector is provided with a circuit control board in the installation box and electrically connected with the external control panel. The effect is: the external interface is simple, easy to install, suitable for the pipeline layout of the existing gas water heater, can directly replace the manual water mixing valve, can realize the recovery of residual water in the pipeline network, and can adjust the water temperature within a certain range.

Description

technical field [0001] The invention relates to a hot water regulating device, in particular to a water-saving intelligent hot water regulator and a control method thereof. Background technique [0002] As a commonly used household appliance, water heaters have been widely popularized. Existing water heaters are usually divided into electric water heaters and gas water heaters. For gas water heaters, due to the high safety requirements for gas pipeline laying, most users It is to hang the gas water heater near the kitchen, and use one water heater to supply hot water to multiple water points, such as figure 1 As shown, when the house is decorated, hot water pipes and cold water pipes are arranged in the room, and a water mixing valve is set at the water point to meet the supply of cold and hot water. [0003] However, based on the existing house layout, some families often have a certain distance between the kitchen and the bathroom, and the pipeline layout does not necessa...

Problems solved by technology

[0003] However, based on the existing house layout, some families often have a certain distance between the kitchen and the bathroom, and the pipeline layout does not necessarily take the shortest path, resulting in excess water often being accumulated in the pipeline between the water heater and the water point. Every time hot water is needed, the remaining water in the pipeline needs to be drained before new hot water arrives, resulting in waste of water

[0004] In response to the above defects, it was proposed to recover the remaining cold water in the pipeline by setting up a cold water recovery device, such as a water heater saving cold water device disclosed in Chinese patent 201610004179.7, and a water heater invalid cold water recycling system disclosed in Chinese patent 201510213868.4. However, after careful analysis, it is found that various existing improved equipment often need to change the indoor pipe network system, the cost of modification is high, it is difficult to produce various systems, and various additional components will occupy part of the indoor space. Water is often supplied separately and temperature regulation is difficult
