Be provided with first temp probe in the described heat collection water tank, be provided with second temp probe in the described water tank, described heat collection water tank is communicated with by circulating line with water tank, and described circulating line is provided with circulating driving device and circulating electromagnetic valve.According to the program setting, the temperature difference of first temp probe and second temp probe is during greater than first desired temperature, circulating driving device and circulating electromagnetic valve are opened, water in two each and every one water tanks circulates by circulating line, temperature difference up to two water tanks reaches second desired temperature, stop circulation, circulating driving device and circulating electromagnetic valve are closed simultaneously; Wait for circulation for the second time.Improve the water temperature in the water tank so gradually, reached a heating process.
Described water tank is provided with relief tube, on the circulating line that described circulating driving device is located at water outlet of water tank is connected, described circulating line also is provided with the hot water outlet pipe in the water outlet side of circulating driving device, described hot water outlet pipe is provided with the water outlet sniffer, and described circulating electromagnetic valve is located at water outlet of water tank to the circulating line of hot water outlet pipe junction with external position.When opening hot water outlet pipe's valve, the water outlet detection that is contained on the pipeline arrives water, and at this moment circulating driving device is opened, circulating electromagnetic valve is closed, the hot water of carrying through circulating driving device is not to enter circulation, but flows out from the hot water outlet pipe, so just can use hot water.
Described circulating electromagnetic valve is located on the circulating line between hot water outlet pipe junction and the heat collection water tank water inlet.
Described water tank is provided with cold water inlet, low level liquid level sensor and high-order liquid level sensor, and described cold water inlet is provided with entering water electromagnetic valve.When low level liquid level sensor probe value set value less than lowest water level, entering water electromagnetic valve was opened, and began to be water on the water tank; Up to the peak level setting value that the liquid level sensor that attains to a high place detects, entering water electromagnetic valve is closed, and finishes one and goes up the water process.
Described water heater also comprises light sensor.Described light sensor is located on the heat collecting sheet.When the light that detects when light sensor is lower than minimum light intensity setting value (as night), the circulating driving device operation makes water to the small part in the heat collection water tank be placed in the water tank, leave the space that water freezing expands this moment in the heat collection water tank, even ambient temperature is low to making the water freezing in the heat collection water tank expand, can not burst damage to heat collection water tank yet.When the The sun came up on daytime, solar radiation is after on the heat collecting sheet, and the temperature difference that the water in the heat collection water tank is heated to water in heat collection water tank and the water tank is during greater than first desired temperature, and circulating driving device moves, make the water of two water tanks circulate, and the water level in the heat collection water tank is got back to normal level.
Described water heater also comprises control module, is used for the operation of each electronic unit of water heater is controlled.Described first, second temp probe, high and low liquid level sensor, circulating driving device, water outlet sniffer, light sensor and each magnetic valve all link to each other with control module, described each temperature, liquid level and light intensity setting value are set by control module, temp probe, liquid level sensor, water outlet sniffer and the detected signal of light sensor pass to control module, after in control module, comparing judgement, carry out signal by control module output again and give performance elements such as magnetic valve, circulating driving device with setting value.
The utility model advantage is:
1. the utility model absorbs the heating of feeding water of heat on the heat collecting sheet by heat collection water tank, and heat transfer area is big, the efficient height.
2. the utility model is provided with light sensor, can when night, light died down the water in the heat collection water tank be emitted, and prevents that water freezing from expanding and the damage heat collection water tank, and frost resistance is good.
3. the utility model complete machine is no pressure-bearing type, and cost is low.
