Summary of the invention is subjected to the restriction of height for the installation site that overcomes the prior solar water heater water storage tank, and solve in the top layer user hot water effluent insufficient pressure, low layer user pipe of existing solar water heater the cold water emptying amount and greatly, manually add cold water injection and easily produce water resource waste, shortcomings such as influence is attractive in appearance are installed, the utility model provides a kind of solar water heater, the water storage tank installation site of this water heater is not subjected to the restriction of height, the discharge pressure of hot water can satisfy instructions for use, and has the function that adds cold water injection automatically.

The technical scheme that its technical problem that solves the utility model adopts is: the solar energy water storage tank is vertically placed, vacuum heat collection pipe from top to bottom successively level insert the sidepiece of water storage tank.Place piston in the water storage tank, piston is divided into two containers up and down with water storage tank.Piston is the last solid that all is matrix, and weight is greater than its buoyancy and static friction force sum, makes the piston can sedimentation when container connects up and down.Two parallel piston rings up and down are equipped with in the piston side, and piston ring contacts with the tank inner wall face.The distance of two-piston interannular is greater than the caliber of vacuum heat collection pipe, prevents that container up and down is connected the side opening conducting by water storage tank and vacuum heat collection pipe.Conducting valve is installed on the piston, and control is the perforation and the sealing of two containers up and down.Original state, piston are positioned at the bottom of water storage tank, and this moment, the volume of bottom container was zero substantially, and the volume of upper container is suitable with water storage nationality overall volume.When the water in the upper container is heated and brings into use hot water, this moment to the following water inlet filling running water of water tank bottom, under the effect of tap water pressure, conducting valve is closed, running water promotes piston and moves upward, the upper container volume diminishes, and heat hydraulic pressure wherein increases, and hot water is discharged water storage tank upper water-out mouth.When water inlet stopped to annotate running water instantly, tap water pressure disappeared in the bottom container, and conducting valve recovers conducting state, make two containers perforation up and down, piston overcomes its buoyancy and frictional resistance under the gravity effect, move down, the cold water in the bottom container enters upper container by conducting valve.Running water adds water inlet under the water storage tank, and piston moves up, and has promptly reached the purpose of opening hot water; Stop to add running water, piston moves down, and has promptly reached the purpose of closing hot water, adding cold water injection.

The beneficial effects of the utility model are, the water heater water storage tank can be installed under user's the balcony or windowsill, and the discharge pressure of hot water still can satisfy instructions for use; Connecting pipe between water storage tank and hot water outlet is short, and major part passes indoorly, and the cold water emptying amount is little in the pipeline, hot water thermal insulating is effective, the pipeline long service life; Water storage tank adds cold water injection automatically, does not have the run, drip, leak phenomenon of water; Simple in structure.
