The solar water heater that has many cabins formula water tank
Technical field
The utility model relates to a kind of solar water heater that has many cabins formula water tank, belongs to technical field of solar water heaters.
Background technology
Along with the development of modern social science technology, increasing people uses the equipment of the solar water heater of energy-conserving and environment-protective as the household water heating.Solar water heater mainly comprises the thermal-arrest plate of a water tank that is used for water storage and a heating cold water; There is the special coating of one deck on the thermal-arrest plate surface of solar water heater; This coating has very big absorptivity to the solar visible light scope, be absorbed as heat after, the heat radiation heat radiation wavelength of thermal-arrest plate is at long wave limit; This coating is very low to the emissivity of long wave, has so just effectively kept the heat of solar thermal energy.Cold water gets in the water tank of solar water heater through pipeline, passes through the thermal-arrest plate then, and the thermal-arrest plate is heated to be hot water gradually with cold water.Because the proportion of cold water is more great than the ratio of hot water, automatically toward rising, get back to again in the water tank of solar water heater after the cold water in the thermal-arrest plate is heated to be hot water, and water in water tank entering thermal-arrest plate heats, and has so just formed a circulation power.
In prior art, when overcast and rainy, owing to there is not the cold water in the sun solar water heater can't be heated to sufficiently high water temperature; Normally bathing of people; Can heat the warm water in the solar water container this moment through electrically heated mode, because water tank volume is big, heat time heating time is very slow; And when people use with not falling so many water, caused the energy and waste of time.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned weak point; Thereby a kind of solar water heater that has many cabins formula water tank is provided, can when reducing the energy and waste of time, provides life to use hot water to people, simple in structure; Easy to use, reached purpose of energy saving very efficiently.
According to the technical scheme that the utility model provides, the solar water heater that has many cabins formula water tank mainly comprises water tank, thermal-arrest plate, water inlet pipe, outlet pipe, electrical heating resistance and thermal insulation board, connects the thermal-arrest plate in the water tank lower end.A plurality of thermal insulation boards are set in the said water tank, water tank are separated into a plurality of cabins through thermal insulation board, embodiment illustrated in fig. 1 for two thermal insulation boards are set, water tank is separated into three cabins.
Said thermal insulation board is provided with the inlet opening.
Said water tank two ends connect water inlet pipe and outlet pipe respectively.
Water tank one side near outlet pipe is provided with electrical heating resistance.
Compared with present technology the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; Reached purpose of energy saving very efficiently, easy to use, heat time heating time is short.

The specific embodiment
Following the utility model will combine the embodiment in the accompanying drawing to further describe:
As shown in Figure 1, the utility model mainly comprises water tank 1, thermal-arrest plate 2, water inlet pipe 3, outlet pipe 4, electrical heating resistance 5 and thermal insulation board 6, connects thermal-arrest plate 2 in water tank 1 lower end.A plurality of thermal insulation boards 6 are set in the said water tank 1,, can water tank 1 be separated into a plurality of cabins through thermal insulation board 6 according to the needs of different situations, embodiment illustrated in fig. 1 for two thermal insulation boards 6 are set, water tank 1 is separated into three cabins.
Said thermal insulation board 6 is provided with inlet opening 7, and current cabin from water tank 1 from inlet opening 7 arrives another cabin.
Said water tank 1 two ends connect water inlet pipe 3 and outlet pipe 4 respectively, and cold water gets into from water inlet pipe 3, and the water after the heating flows out from outlet pipe 4.
Water tank 1 one sides near outlet pipe 4 are provided with electrical heating resistance 5, heat the water that electrical heating resistance 5 heats this place through electric energy.
The operation principle of the utility model is: when the sun was arranged, the heat that the thermal-arrest plate 2 of solar water heater is collected enough heated water temperature, then need not to open electrical heating resistance 5 and carries out electrical heating.Cold water gets into from water inlet pipe, through finally from outlet pipe 4, flowing out after 2 heating of thermal-arrest plate.
When not having the sun overcast and rainy, open in 5 pairs of water tanks 1 of electrical heating resistance and heat near the higher relatively water of the temperature in the outlet pipe 4, with minimum electric energy warm water is heated.Use the light time when the water at this place, then compensate through the water in the adjacent cabin.
The utility model makes full use of natural solar energy, is not enough to provide under the situation of heat at solar energy, through electrically heated mode hot water is provided, and both energy-conserving and environment-protective do not influence the use of daily life again.
