Description
Technical field
The present invention relates to technical field of solar water heaters, relate in particular to a kind of solar water heater water tank, also relate to a kind of solar water heater.
Background technology
Along with the raising of living standards of the people, water heater application in daily life more and more widely.
Existing water heater is divided into combustion gas, fire coal, fuel-oil water heater according to energy source, and several big classes such as electric heater.Above-mentioned combustion gas, fire coal, fuel-oil water heater consumption all are non-renewable energy resources, also cause the pollution of environment; Simultaneously, continue surging today in energy prices, the cost of use of above-mentioned combustion gas, fire coal, fuel-oil water heater is very high, has brought bigger financial burden to the user.Because power consumption is big, electricity price also has the trend of sustainable growth, and also there is no small obstacle in the extensive use of above-mentioned electric heater.
Under this background, advantage is widely used solar water heater so that its energy clean environment firendly, cost of use be lower, easy to use etc., and this will bring significant impact to Chinese national economy and environmental protection cause.
Please referring to Fig. 1, Fig. 1 is the structural representation of a kind of common solar water heater in the prior art.
As shown in Figure 1, the solar water heater of this structure comprises heat collector 11 and water tank 12.
The effect of heat collector 11 is the interior energy that absorb the energy of solar radiation and be translated into heat collector 11.Be provided with the pipeline that the stream that can supply water passes through in the heat collector 11, the end of heat collector 11 is provided with inlet 11-1 and liquid outlet 11-2, also be provided with water inlet 12-1 and delivery port 12-2 on the water tank 12, the delivery port 12-2 of water tank 12 is communicated with the inlet 11-1 of heat collector 11, the liquid outlet 11-2 of heat collector 11 is communicated with the water inlet 12-1 of heating water tank 12, heat collector 11 and the circulation canal of water tank 12 by a closure of pipeline formation.
Cold water in the water tank 12 enters in the heat collector 11, flow in the pipeline of cold water in heat collector 11 and form current, current and heat collector 11 carry out heat exchange, the solar radiation energy of heat collector 11 absorptions is converted into the interior energy of current, thereby realize heating to current, heated current return in the heating water tank 12, and the cold water in the heating water tank 12 enters heat collector 11 again, by continuous circulation the cold water in the water tank 12 are heated to proper temperature.Heating water tank 12 also is provided with hot water outlet 12-3 and cold water inlet 12-4, cold water inlet 12-4 is communicated with water supply pipe by tube connector, can inject cold water by cold water inlet 12-4 in heating water tank, hot water outlet 12-3 is connected with the terminal water nozzle by tube connector.
In water tank 12, inject the process of cold water from cold water inlet 12-4, because the volume of water tank 12 is limited, the cold water itself that comes out from water supply pipe has big pressure, if the amount that cold water injects is too much, to produce very big pressure to the inwall of water tank 12, even can cause the generation of water tank fracture phenomena, moreover, because after cold water is heated to form the higher hot water of temperature, cold water is heated and can expands, it is big that volume becomes, bigger to the pressure of the inwall of water tank 12, therefore, need control the amount that enters the cold water in the water tank 12, in order to avoid the amount of cold water too much causes the pressure of tank inner wall excessive.
In the prior art, a level sensor is set in water tank 12 usually, on the tube connector between water supply pipe and the cold water inlet 12-4, be provided with water solenoid valve, level sensor is used to detect the height of water level in the water tank 12, and send the water level altitude signal, when the height of water level in the water tank 12 surpassed the preset water level height, water solenoid valve was closed in the control, stopped to go up in water tank 12 water.The preset water level height is set according to the pressure that water tank 12 can bear, and when the height of water level in the water tank 12 arrives default height of water level, just no longer injects cold water in water tank 12, thereby water tank 12 is played a protective role.
But, level sensor, go up water solenoid valve and be perishable product, if one is broken down, cisco unity malfunction can not normally be controlled cold water and enter height of water level in the water tank 12, thereby can't play the effect of protection water tank 12.
