Water saving system for saving household water and operation method

Abstract

The invention relates to a water saving system for saving household water and an operation method. The water saving system comprises a heating device connected with a cold water pipe and a hot water pipe, and an outflow controller communicating with the hot water pipe and the cold water pipe, wherein the outflow controller is provided with a hot water output end and a cold water collection port, the cold water collection port communicates with a collection pond through a cold water collection pipe, and a temperature induction switch is arranged at the position of the cold water collection port. A controller is further included and comprises a temperature controller and a cold water outflow switch control unit, and the controller is in signal connection with the temperature induction switch. The temperature controller presets the temperature value, and when the temperature reaches the preset temperature value, the cold water outflow switch control unit controls the temperature inductionswitch to be turned off; and when the temperature is lower than the preset temperature value, the cold water outflow switch control unit controls the temperature induction switch to be turned on. According to the water saving system and the operation method, in the hot water usage process, water getting lost at various output ports and not reaching the preset temperature can be collected, energysaving and environment friendliness are achieved, the economic benefits are improved, and operation is simple.

Description

technical field [0001] The invention belongs to the intersection fields of house construction, water supply and drainage, and intelligent automation, and in particular relates to a water-saving system and an operation method for saving household water. Background technique [0002] Gas water heaters have the characteristics of environmental protection, safety, and high efficiency. They are one of the main household appliances for domestic hot water supply. Under normal circumstances, due to considerations of economy and space-saving utilization, the average family will only install one gas water heater to meet the needs of showering, heating, washing, and hot water in the kitchen. [0003] However, due to the limited number of installed water heaters, the number of hot water outlets used by households is relatively large, such as shower rooms, kitchens, washrooms, and laundry rooms, and usually the locations of each output end are different. The distance between the termina...

[0003] However, due to the limited number of installed water heaters, the number of hot water outlets used by households is relatively large, such as shower rooms, kitchens, washrooms, and laundry rooms, and usually the locations of each output end are different. The distance between the terminals varies from far to near. After each output terminal is turned on, the water flows out. Before the water temperature reaches the expected temperature, there will be water loss and waste of different volumes lower than the expected temperature. Take an output terminal with a distance of about 10m from the water heater as For example, after turning on the output end once, 10kg-20kg of water needs to flow out to reach the preset temperature value. A family of three showers once a week on average, and the number of showers in a month is as high as 120kg-240kg. This is just a shower. Part of it does not include the amount of water lost at other outlets. If the amount of water wasted at the other outlets of hot water is included, it is astonishing. Therefore, it can be seen that the amount of water wasted by using hot water in each family is huge.
