Abstract
A water-saving device of a water heater comprises a temperature sensor, a first electromagnetic valve, a liquid level sensor, a second electromagnetic valve and a water storage tank. The temperature sensor, the first electromagnetic valve, the liquid level sensor and the second electronic magnetic valve are connected with a single-chip microcomputer module. The water storage tank is connected with a water supply channel of the water heater. The temperature sensor is mounted inside the water supply channel of the water heater. The liquid level sensor is mounted inside the water storage tank. When the water-saving device is used, cold water flows into the water storage tank after a switch of the water heater is turned on. When temperature reaches a set value, the electromagnetic valves are started, the channel of the water storage tank is closed and a spray passage is opened. The water storage tank uses cold water for cold supplying and heating. Once level of water in the water storage tank is lower than a set level, the cold water for supplying cold and heating is transferred to a tap water pipe for water supply, and accordingly effective water conservation is achieved.

The specific embodiment
A kind of water-saving device of water heater comprises temperature sensor 1, the first magnetic valve 2-1, liquid level sensor 3, the second magnetic valve 2-2, storage tank 4; Said temperature sensor 1, the first magnetic valve 2-1, liquid level sensor 3 are connected one-chip computer module 5 with the second magnetic valve 2-2; Said storage tank 4 connects water supply of water heater passage 6, and said temperature sensor 1 is installed in the water supply of water heater passage 6, and said liquid level sensor 3 is installed in the storage tank 4.
Said first magnetic valve 2-1 control shower head intake tunnel 7 and storage tank 4 intake tunnels; Said second magnetic valve 2-2 control storage tank 4 exhalant canals and running water pipe passage 8.
Said one-chip computer module 5 connects temperature module 9 and temperature display module 10 is set.
Through temperature module 9 is set temperature is set at desired value, when water temperature reached setting value and uses water heater, the water that begins to emit was the cold water in one section water pipe, by temperature sensor 1 and first magnetic valve 2-1 control, this section cold water is drained into storage tank 4 storages.
Using; Possibly need cold water to regulate the water temperature when taking a shower, at this moment, the cold water of storage tank 4 capable of using is regulated; After the cold water of storage tank 4 uses up; Then, required cold water channel is transferred on the running water pipe automatically, supplies water by running water pipe again and regulate water temperature by liquid level sensor 3 and second magnetic valve 2-2 control.
As shown in Figure 2, when using the water heater shower, because leading portion is a cold water between shower head and the water heater that is:, at this moment, temperature sensor 1 and the common control of the first magnetic valve 2-1 are received storage tank 4 with this section cold water and are stored.The first magnetic valve 2-1 normality is for stopping up shower head intake tunnel 7.That is: when the water temperature of obtaining when temperature sensor 1 is lower than the shower temperature of setting; The first magnetic valve 2-1 stops up shower head intake tunnel 7; The water that lets this moment, water temperature is lower than the shower temperature of setting, stores in the storage tank 4 intake tunnels inflow storage tank 4 through three links.When the water temperature of temperature sensor 1 measurement was equal to or higher than the shower temperature of setting, the first magnetic valve 2-1 started working, and is transformed into the B point by the A point, stopped up storage tank 4 intake tunnels, hot water turn of tidal stream to shower head intake tunnel 7.
As shown in Figure 3, during shower, the water temperature in the time of possibly regulating shower with cold water at this moment, is controlled by the liquid level sensor 3 and the second magnetic valve 2-2 jointly, regulates the shower head water temperature to reach the cold water of confirming with storage tank 4 stores.The second magnetic valve 2-2 normality is for stopping up running water pipe passage 8, and the normality of promptly working is for using the water of assembling in the storage tank 4, the water temperature when regulating shower with running water.That is: when storage tank 4 water levels of liquid level sensor 3 tests are higher than the water level of setting; The second magnetic valve 2-2 stops up running water pipe passage 8, regulates the water of shower water temperature this moment and is supplied with by storage tank 4, in case when storage tank 4 water levels that liquid level sensor 3 obtains are lower than the water level of setting; The second magnetic valve 2-2 starts working; Be transformed into the D point by the C point, stop up storage tank 4 exhalant canals, be transformed into by the running water pipe water temperature when regulating shower that supplies water.
The first magnetic valve 2-1 is the water temperature conversion electromagnetic valve; The second magnetic valve 2-2 is the water level conversion electromagnetic valve.They carry out automatic switching motion under one-chip computer module 5 controls, change the water stream channel effect thereby arrive.
The course of work is as shown in Figure 5:
Energized at first, system starts working.At this moment, the minimum water temperature X of shower artificially is set
0, system is provided with storage tank 4 lowest water level H automatically
0Then, temperature sensor 1 is started working respectively with liquid level sensor 3, and testing result is sent to one-chip computer module 5 respectively; Again by one-chip computer module 5 control the first magnetic valve 2-1 respectively, the second magnetic valve 2-2 changes; Thereby reach the waste that has both prevented cold water in the leading portion water pipe, will collect again in the storage tank 4 that cold water uses again in the leading portion water pipes, reach the purpose of using water wisely, prevention waste.
Temperature is set earlier.As 40 ℃, open the heater switch, temperature is lower than 40 ° of C and flows into storage tank 4, and when temperature reached 40 ℃, the first magnetic valve 2-1 rotated under the control of one-chip computer module 5 and closes storage tank 4 intake tunnels, transferred to opening shower place passage, can take a shower.In the process of having a bath, possibly regulate the temperature of shower head water outlet with cold water, at this moment only need the mixed water valve 11 on the shower head be rotated to an angle to the cold water direction gets final product.The cold water that is used to regulate water temperature this moment is the water in the storage tank 4; Water in storage tank 4 uses up; Liquid level sensor 3 both can detect; At this moment, the one-chip computer module 5 controls second magnetic valve 2-2 carries out the automatic conversion of storage tank 4 and tap water supply, will be supplied water by running water pipe after the conversion and regulate the water temperature of shower head.
