Description
Technical field
The utility model relates to the improvement of domestic solar water heater's water system structure, and this structure also is applicable to storage-type electric water heater.
Background technology
The domestic solar water heater is used more and more widely because of advantages such as its energy-saving and environmental protection, safety.Its structure is except that the solar energy heating device, and its water system comprises inlet valve, water inlet pipe, storage tank, outlet pipe and flowing water Valve, connects running water pipe and storage tank by water inlet pipe, at running water pipe and water inlet pipe junction device inlet valve; Connect storage tank and water heater terminal by outlet pipe, connect water heater end device flowing water Valve at outlet pipe.By the design of existing solar water heater, be installed in the roof with heat collector or towards the exterior wall in south, towards the balcony in south in order to the storage tank of stored hot water.And the bathroom is many at the position of this cover dwelling house by the north side.Therefore, storage tank is to the terminal of water heater---the quite long segment distance of depotition cock.When using hot water, the water discharging in advance of having cooled off in the outlet pipe could need be flowed out hot water afterwards at every turn.The water temperature and the environment temperature of the length of cold water discharge rate and outlet pipe, the heat-insulating property of water pipe, water tank are relevant, that is to say that pipeline is long more, heat-insulating property is poor more, the water tank water temperature is low more, environment temperature is low more, need the cold water of discharging just many more.The water of this part discharge is clean water, can collect in the family that has to reuse, as flush the toilet etc., more family then directly enters sewer because do not want to take the trouble with this part cold water in the outlet pipe, causes water resource waste.According to parties concerned's statistics, single family needs the cold water of discharging to be about the 10-30 liter before using the solar water heater bathing at every turn, if the user of wide geographic area is calculated, the water number amount that is wasted is surprising.
For the family that uses electric heater, the length of its water inlet pipe and outlet pipe is wanted much shorter than solar water heater, but the situation that also exists the cold water of outlet pipe to be wasted.
The utility model content
Technical problem to be solved in the utility model is, a kind of domestic solar water heater's of being applicable to heating system is provided, and also is applicable to storage-type electric water heater, and it can be collected the cold water in the outlet conduit again and utilize.
The realization the technical solution of the utility model is, a return pipe is set between outlet pipe and water inlet pipe, and return pipe and water inlet pipe, water tank, outlet pipe form a backwater path.Wherein, return pipe is connected at close flowing water Valve place with outlet pipe, at any position of the water inlet pipe that is positioned at the backwater access structure, outlet pipe or return pipe water pump is set, and backwater valve is set on return pipe.
Operation principle of the present utility model is: when not using the hot water of water heater, close backwater valve, water pump is in the state of closing down, and the backwater path is in closed condition, and current pass through but do not stop up and down; When the hot water in the needs use solar water heater, open backwater valve and start water pump, because the power of water pump, cold water in the outlet pipe enters storage tank by return pipe and water inlet pipe, and the hot water in the storage tank enters outlet pipe, and the cold water in outlet pipe is all replaced by the hot water in the storage tank, the hot water flowing water Valve place that goes directly, switch off the pump and backwater valve, open flowing water Valve this moment, outflow be exactly hot water.So the waste that discharging cold water causes has been eliminated by system.
Described water pump can be manual, also can be electronic.Wherein preferred electric water pump.When using electric water pump, can also a temperature sensor respectively be installed at storage tank and return pipe, and be equipped with computer controller, stop keying with back-water valve (BWV) according to the difference decision water pump of two place's water temperatures moving.When the outlet pipe water temperature reduces, to compare when reaching certain gap with the water temperature of storage tank, backwater valve is opened, starting mode of pump, the backwater path is started working; When the hot water of storage tank progressively enters outlet pipe and return pipe, the water temperature of return pipe is identical with the water temperature of storage tank or when being close, backwater valve is closed, and water pump is closed down, and the backwater path quits work.The solar water heater of automatic control system like this has been installed, and what open the outflow of water heater terminal at any time all is hot water, has not only avoided the waste of water, has also saved the trouble of discharging cold water.
In view of the water inlet pipe initiating terminal and the outlet pipe end of solar water heater generally all is arranged in the bathroom, just inlet valve and flowing water Valve from very near, so the utility model is very simple for the conventional solar boilers water system installs return pipe additional.At water-in and water-out valve closing state, outlet pipe almost is identical with the water inlet inner pipe water pressure, and therefore when starting water pump, the required power of water circulation in the backwater path is very low.Used water pump can use the 12V power supply, can guarantee user's safety.According to measuring and calculating, but 10 tons in pump water is spent in the every power consumption 1 of water pump.By electric 0.44 yuan of the every degree in Beijing in 2009,3.7 yuan of calculating of water per ton, the utility model is every expenditure 1 yuan in the electricity charge, can save 84 yuan of water rates.
