Summary of the invention
For overcoming above-mentioned deficiency, the purpose of this utility model is that a kind of solar water heater cold-water reflux device is provided to this area, makes it solve existing like product structure comparatively complicated, uses the comparatively technical problem of inconvenience.Its objective is and be achieved through the following technical solutions.
A kind of solar water heater cold-water reflux device, this device comprises feed pipe, cold water inlet, Single-chip Controlling panel, water-heater water tank, hot water outlet pipe.Its structural feature is that described hot water outlet pipe connects temperature detect switch (TDS), two-position three way magnetic valve A successively, two-position three way magnetic valve A connects an end of outlet pipe and return duct, outlet pipe connects the outlet valve switch, the other end of return duct connects water pump and two-position three way magnetic valve B successively, and two-position three way magnetic valve B connects described cold water inlet and feed pipe; Described temperature detect switch (TDS), outlet valve switch, two-position three way magnetic valve A, water pump, two-position three way magnetic valve B all connect described Single-chip Controlling panel and form control loop.Unlatching by above-mentioned outlet valve switch control single chip computer chain of command, by temperature detect switch (TDS), realize the detection of leaving water temperature, by the Single-chip Controlling panel, the water temperature testing result is processed, and information is fed back to two-position three way magnetic valve A, two-position three way magnetic valve B and water pump, by two-position three way magnetic valve A, two-position three way magnetic valve B, water pump three cooperating, realize cold-water reflux, not reaching the water that sets temperature in the hot water outlet pipe is back in water-heater water tank, can not only reach the purpose of water saving like this, and temperature is controlled during water more comfortable.
Be connected storage tank between described return duct and described water pump, be provided with the water level inductive switch in storage tank, the water level inductive switch is electrically connected to described control loop, and storage tank connects an adjutage, adjutage connecting valve valve.By storage tank is set, and connect an adjutage with switch valve on storage tank, its purpose one is to reduce the water pump number of times of start-up operation repeatedly, extends water pump service life, the 2nd, and when water pump goes wrong, can be by the adjutage operation that discharges water in time.Certainly, the water that this adjutage is emitted can be used as daily water consumption and uses.
The utility model structure is comparatively simple, uses operation more for convenience, and water-saving result is good, and be suitable as the solar water heater that possesses water-saving function and use, or the architecture advances of like product.
The accompanying drawing explanation
Fig. 1 is scenario-frame schematic diagram of the present utility model.
Fig. 2 is the improvement project structural representation of Fig. 1.
In figure, the name of sequence number is called: 1, cold water inlet, 2, the Single-chip Controlling panel, 3, water-heater water tank, 4, hot water outlet pipe, 5, temperature detect switch (TDS), 6, two-position three way magnetic valve A, 7, the outlet valve switch, 8, outlet pipe, 9, return duct, 10, water pump, 11, two-position three way magnetic valve B, 12, feed pipe, 13, storage tank, 14, the water level inductive switch, 15, adjutage, 16, switch valve.
The specific embodiment
Now by reference to the accompanying drawings, the utility model is further described.
As described in Figure 1, this solar water heater cold-water reflux device comprises cold water inlet 1, Single-chip Controlling panel 2, water-heater water tank 3, hot water outlet pipe 4, temperature detect switch (TDS) 5, two-position three way magnetic valve A6, outlet valve switch 7, outlet pipe 8, return duct 9, water pump 10, two-position three way magnetic valve B11, feed pipe 12.The hot water outlet pipe connects temperature detect switch (TDS), two-position three way magnetic valve A successively, two-position three way magnetic valve A connects an end of outlet pipe and return duct, outlet pipe connects the outlet valve switch, the other end of return duct connects water pump and two-position three way magnetic valve B successively, and two-position three way magnetic valve B connects cold water inlet and feed pipe.Temperature detect switch (TDS), outlet valve switch, two-position three way magnetic valve A, water pump, two-position three way magnetic valve B all connect the Single-chip Controlling panel and form control loop.
The specific works principle of this solar water heater cold-water reflux device is: above-mentioned two-position three way magnetic valve A adopts the control mode of one-in-and-two-out, and two-position three way magnetic valve B adopts two to advance a control mode out.When opening the outlet valve switch of outlet pipe, the Single-chip Controlling panel will start work, temperature by water in temperature detect switch (TDS) induction hot water outlet pipe, when temperature does not meet the set definite value of Single-chip Controlling panel, to control two-position three way magnetic valve A conducting hot water outlet pipe and return duct, two-position three way magnetic valve B conducting return duct and cold water inlet, and startup pump working, make cold water inlet, water-heater water tank, hot water outlet pipe, return duct form circulating water flow, realize the quick-cooling, heating of current alternately, realize the cold-water reflux operation.When temperature detect switch (TDS) detects the compound setting value of water temperature, will control two-position three way magnetic valve A conducting hot water outlet pipe and outlet pipe, outlet pipe flows out hot water, two-position three way magnetic valve B conducting cold water inlet and feed pipe, and stop pump working.
In conjunction with said structure, to the utility model, also can do following improvement: as shown in Figure 2, between return duct and water pump, be connected storage tank 13, be provided with water level inductive switch 14 in storage tank, storage tank connects an adjutage 15, adjutage connecting valve valve 16.Water level inductive switch and switch electromagnetic valve all are electrically connected to the Single-chip Controlling panel.By storage tank is set, make the cold water in the hot water outlet pipe first in return duct is back to storage tank, when the water level sensor in storage tank is sensed water level and is transfinited, to control two-position three way magnetic valve B conducting return duct and cold water inlet by the Single-chip Controlling panel, and the unlatching water pump, the water in storage tank will be back in water-heater water tank through return duct, cold water inlet.Sense water level when low when water level sensor, will control two-position three way magnetic valve B conducting cold water inlet and feed pipe by the Single-chip Controlling panel, and switch off the pump.By with upper type, reduce the water pump number of times of start-up operation repeatedly, extend water pump service life.Storage tank connects adjutage, and adjutage connecting valve valve, when water pump breaks down, can discharge the water in storage tank in time by switch valve, and the water in storage tank also can be used as domestic water and uses.
