For how preventing that pipeline from being frozen, general method is to add electrical heating mechanism to around the pipeline, not only uses and loses time, and expend a large amount of electric energy.
In the place that a lot of solar water heaters are used, as in building constructions, usually because the connecting pipe between solar water heater delivery port and the user's water intaking is longer, before the user uses water heater, residual fraction cold water usually in the pipeline, user's common practices is that it is bled off, and up to emitting hot water, this just causes the significant wastage of water resource.Therefore and the water yield of wasting is 4710 milliliters according to investigation result estimation, general building 6-12 layer is averaged 10 layers, and the average distance between water heater delivery port and user's intake surpasses 15 meters, and getting pipe diameter is 20 millimeters calculating; Calculate with a hot water according to average two days of each household, the waste water yield in 1 year of each household is 859 liters so; Calculate according to whole residential building 300 families, the wastage in 1 year reaches 257 tons.
For the cold water that how effectively to utilize in the pipeline, in novel " solar water heater water-saving box " 200620019421.X of existing way of water-saving technology field such as practicality and patent of invention " a kind of solar water heater that has circulation water saving device " 200710099409.3, these two kinds all need additionally to increase water tank, in water heater production, both increased the complexity of production process, also increased the production cost of water heater, though feasible, be difficult for promoting.
Summary of the invention
In order to effectively utilize water heater, and in order to prevent that winter, water pipe freezed to the cold water between user's intake, the present invention at delivery port to having increased reflux line and reflux cycle pump between the water heater.When the user uses, if water is cool excessively, manually boot EGR, reach and recycle the purpose that cuts the waste; When detecting water temperature and be about to reach the freezing point winter, start the reflux cycle pump automatically, utilize the hot water in the water tank, reach and prevent the purpose that freezes.
Fig. 1 is a structural representation of the present utility model, a kind of multifunction water-saving solar water heater comprises positive threeway (1), circulation pipe (2), radiator drain (3), water circulating pump (4), temperature sensor (5), water tank (6), level sensor (7), steam vent (8), water intaking valve (9), tank inlet pipe (10), cool water pipe (11), cold water valve (12), mixes water valve (13), water pipe (14).
Steam vent (8) is positioned at water tank (6) top, and level sensor (7) is positioned at water tank (6) inside, and tank inlet pipe (10) is communicated with water tank (6) top by water intaking valve (9).Connecting two parallel pipelines in water tank (6) bottom of solar water heater is radiator drain (3) and circulation pipe (2), two pipelines are communicated with by positive threeway (1), constitute loop, simultaneously positive threeway (1) another port is connected by mixing water valve (13) with cool water pipe (11), water pipe (14).Post temperature sensor (5) in circulation pipe (2), water circulating pump (4) is installed on the circulation pipe (2), and level sensor (7) is installed in the water tank, and water circulating pump (4) is subjected to manually by control circuit and temperature is controlled jointly.
Fig. 2 is the control circuit figure of water circulating pump of the present utility model, comprises battery main switch Q, fuse FU, pump motor M, electrothermal relay FR, relay K M, contactor main contacts KM1, shift knob SB1, SB2, temperature detect switch (TDS) K1, water level switch K2.Battery main switch Q is positioned on the bus, shift knob SB2 is in parallel with temperature detect switch (TDS) K1, and connect relay K M control contactor main contacts KM1, the duty of main contacts KM1 control water circulating pump (4) with shift knob SB1, water level switch K2, electrothermal relay FR, relay K M.
The technical solution of the utility model principle is as follows:
To mix water valve (13) closes, circulation pipe (2), radiator drain (3) and positive threeway (1) constitute loop, water circulating pump (4) is arranged on this loop, level sensor (7) is related with water level switch K2, when not having water in the water tank (6), water level switch K2 disconnects, water circulating pump this moment (4) can not worked, when water is arranged, water level switch K2 closure, temperature sensor (5) is related with temperature detect switch (TDS) K1, temperature detect switch (TDS) closure when temperature is below the freezing point in circulation pipe (2) pipeline, the control circuit path, when being higher than freezing point, temperature detect switch (TDS) K1 disconnects, control circuit opens circuit, when shift knob SB2 is closed, and the control circuit path, when shift knob SB2 disconnects, control circuit opens circuit, when the control circuit path of water circulating pump (4), and relay K M adhesive, water circulating pump (4) work, water circulates in loop, and the hot water in the water tank (6) is owing to hydraulic pressure flows out by radiator drain (3), and the cold water in the pipeline is owing to the hydraulic pressure effect flows in the water tank (6) by circulation pipe (2) simultaneously, radiator drain (3) is full of hot water very soon, opens mixed water valve (13) and can use.
