Abstract
The utility model discloses a solar water heater with double water tanks, which comprises a heat storage water tank (1) and a heat supply water tank (2) both arranged on a roof. A hot water outlet (3) is arranged at a position 20mm-50mm away from the bottom of the heat storage water tank (1) to be 20-50mm and connected with a water inlet pipe (5) of the heat supply water tank (2) through a communicating pipe (11) and a communicating valve (4), the water inlet pipe (5) is 20mm-50mm away from the top of the heat supply water tank (2), and a float valve (6) for controlling water inlet is arranged in the heat supply water tank (2). The bottom of the heat supply water tank (2) is connected with a user heat supply water pipe (8) through a water outlet valve (7), and elevation of the bottom of the heat storage water tank (1) is larger than that of the water inlet pipe (5) on the heat supply water tank (2). The solar water heat with the double water tanks adopts the double water tanks with different volume, can solve the problem that a single water tank is long in warming time, and can solve the problem that a single water tank is insufficient in water supply. The solar water heater with the double water tanks is simple in structure, easy to construct and convenient to maintain.
Description
Technical field
the utility model relates to a kind of pair of tank solar water heater, belongs to technical field of solar water heaters.
Background technology
in the abundant area of sunlight, a lot of resident families utilize the hot water supply of solar water heater as family.Specific practice is at the high heat-absorbing material of metal water tank surface applied, utilizes the straight solarization of sunshine directly the water in the water tank to be heated, and the overwhelming majority adopts single water tank heat supply at present.If with water tank do too big, firing rate is very slow, the hot water temperature is not enough; If with water tank do littler, though firing rate is fast, the water yield is not enough, hot water is under-supply.
Summary of the invention
The purpose of
the utility model is, a kind of pair of tank solar water heater is provided.Utilize a water tank heat accumulation, another water tank heat supply has well solved the deficiency that single tank solar water heater exists.
The technical scheme of the utility model
a kind of pair of tank solar water heater; Comprise the thermal storage water tank and the heat supply water tank that are located at the roof; Be provided with hot water outlet apart from 20～50mm at the bottom of thermal storage water tank's case; Hot water outlet is connected with the water inlet pipe of coupling cock with the heat supply water tank through cross over pipe, and water inlet pipe is provided with the ball-cock assembly of control water inlet apart from heat supply water tank case top 20～50mm in the heat supply water tank; The heat supply water tank bottom is connected with user's heat supply water pipe through outlet valve; Thermal storage water tank's bottom absolute altitude is higher than the water inlet pipe absolute altitude on the heat supply water tank.
In
aforesaid pair of tank solar water heater, said thermal storage water tank is provided with cooling water inlet, and cooling water inlet is connected with running water pipe through cold valves.
In
aforesaid pair of tank solar water heater, said thermal storage water tank's volume is 2～3 times of heat supply water tank capacity.
In
aforesaid pair of tank solar water heater, the caliber of said cross over pipe and the latus rectum of coupling cock are greater than the caliber of user's heat supply water pipe.
compared with prior art, the utility model adopts the different two water tanks of two volumes, less one is the heat supply water tank, bigger one is heat storage water tank.Because less quantity of water in water tank is few, so firing rate is fast, water temperature is high in the water tank.Bigger quantity of water in water tank is many, and firing rate is slow.If use for a long time, the water temperature difference in two water tanks is little.Bigger water tank replenishes as less water tank.Both can solve the long problem of single water tank warm-up time, can solve the not enough problem of single cistern water supply again.The utility model simple structure is easy to construction, and is easy to maintenance.
