Solar water heater
Technical field
The present invention relates to water heater, particularly relate to a kind of solar water heater.
Background technology
Water heater, according to the difference of thermal source, has solar water heater, EWH and native water heater on cooking stove etc.The water heater that the heat that soil water heater on cooking stove gives out when being and utilizing native stove to light a fire heats water, has the advantage of not power consumption, combustion gas equal energy source.China Patent No. be 2009201265540, authorized announcement date be December 16 in 2009 day, be called in the patent document of " native water heater on cooking stove " and disclose a kind of native water heater on cooking stove.Native water heater on cooking stove in this patent document comprises water tank and the heat(ing) coil for absorbent earth stove heat, and the water inlet end of heat(ing) coil is docking together with water tank, and the water side of heat(ing) coil is provided with depotition cock and blast pipe, and blast pipe links together with water tank.Heat(ing) coil is embedded in native stove during use, water is added in water tank, fetch boiling water tap time, water flows to heat(ing) coil, flows to tap again from water tank, the heat that current are produced by native stove when heat(ing) coil and heating, the steam of generation then flows back in water tank and is condensed thus the heating realized the water in water tank.Soil water heater on cooking stove can time use the vast rural area of native stove freely to obtain hot water, the heat that native stove discharges is made full use of.
But native water heater on cooking stove has the following disadvantages: can produce during heating that adverse current causes the poor fluidity of water, poor fluidity then affects heat transfer effect.The Habitation form in a house, rural area Dou Weiyi family in addition, having large-arealy is not had to make full use of by the roof that the sun is taken a shower, and native water heater on cooking stove can not utilize the roof of this form.Solar water heater utilizes solar energy to carry out manufacture hot water owing to can be arranged on roof, just in time compensate for the above-mentioned deficiency of native water heater on cooking stove.
But existing solar water heater has the following disadvantages: poor fluidity, the poor fluidity of the water in the closed circuit that water tank and solar thermal collector are formed then affect heat transfer effect; Water circulation and the water tank vibration that causes can overseas publicities, and therefore the isolating affection of water tank is poor.
Summary of the invention
First object of the present invention aims to provide a kind of water of running water that can utilize when water tank moisturizing can circulative solar water heater, solves the problem of the poor fluidity of closed circuit.
Second object of the present invention is intended to provide further the solar water heater that a kind of isolating affection of water tank is good, and the water tank solving existing solar water heater vibrates large problem.
Above technical problem is solved by following technical proposal: a kind of solar water heater, comprise water tank and solar thermal collector, described water tank is provided with circulating water intake, circulating water outlet and water supplement port, described solar thermal collector is provided with the 3rd water inlet and the 3rd delivery port, described 3rd water inlet and circulating water outlet link together, it is characterized in that, also comprise cycle promotion device, described cycle promotion device comprises housing, described housing is provided with the first blade wheel chamber and the second blade wheel chamber that keep apart, described first blade wheel chamber is provided with the first water inlet, first delivery port and the first impeller, described second blade wheel chamber is provided with the second water inlet, second delivery port and the second impeller, described second delivery port links together with described water supplement port, described first water inlet links together with described 3rd delivery port, described first delivery port links together with described circulating water intake, water drives the second impeller to go driving first wheel rotation and makes water flow into the first delivery port outflow from the first water inlet when the second water inlet flows into the second delivery port outflow.During use, be docking together by the second water inlet with tap water pipe network, running water enters water tank to realize adding water through the second blade wheel chamber.Drive the second wheel rotation when running water flows through the second blade wheel chamber, the second impeller-driven first wheel rotation, the first impeller to afford redress power to closed circuit, makes circulation more smooth and easy.
As preferably, described first impeller comprises the first impeller shaft, described second impeller comprises the second impeller shaft, described housing is provided with the axis hole of connection first blade wheel chamber and the second blade wheel chamber, described first impeller shaft and the second impeller shaft are all located in described axis hole, the water seal both described first impeller shaft and the second impeller shaft linked together with described gland seal for a pair is provided with in described axis hole, the bearing supporting described first impeller shaft and the second impeller shaft is provided with between described a pair water seal, described water seal is provided with away from the end face of one end of described bearing the annular distending groove extended along water seal circumference, the inner peripheral surface of the madial wall of described distending groove is provided with the slow groove that shakes extended along water seal circumference, the outboard sidewalls of the described slow groove that shakes all is sealed connected together with described impeller shaft.Compact conformation.Water seal arranges distending groove, and the sealing effectiveness of water seal can raise along with the rising of hydraulic pressure, so sealing effectiveness is better.Arrange the slow groove that shakes, when impeller shaft produces radial rocking, the slow groove that shakes can absorb this vibration thus make the vibratory output of the outer transmission of cycle promotion device little, plays the effect of damping.
