During normal the use, control module is controlled the duty of compressor, electrical heating module and Water flow adjusting valve according to the water temperature synthetic determination, and particularly, working condition and the control model of water heater are as follows:
1, when user's water, at first use the hot water in the water tank 4, cold water causes the coolant-temperature gage of water tank 4 to reduce in inlet pipeline enters water tank 4 at this moment.When water temperature is lower than the compressor start temperature of setting in detecting water tank, compressor start, condenser is to the heating of the water in the water tank 4.
2, can the leaving water temperature behind the detection compressor start reach design temperature, if can, then electrical heating module is not opened; If can not reach design temperature, then according to the electrical heating power of the Inlet and outlet water temperature difference and discharge judgement needs, by the controllable silicon of control electrical heating module, export corresponding electrical heating power.
3, be total power output when compressor and electrical heating module, when leaving water temperature does not also reach design temperature, judge according to detected leaving water temperature that the control Water flow adjusting valve is regulated discharge, guarantees that leaving water temperature remains on design temperature.
4, after stopping water, if the temperature of water tank internal water does not reach the temperature of setting, then compressor continues operation, shuts down till design temperature.
Wherein in the 1st step, the compressor start temperature of setting can be the temperature that has defined in the control module, also can be user-defined temperature, and design temperature that can be when using (the 2nd step with during the 3rd goes on foot design temperature) equates also can not wait.Similarly, stop water in the 4th step after, the design temperature of water also can be the temperature that has defined in the control module in the water tank, also can be user-defined temperature.

When 1) detecting leaving water temperature and be higher than design temperature, control magnetic valve 14 is opened the release branch roads, makes compressor 1 exhaust enter evaporimeter 18 behind release condenser 19 and release capillary 17; Continue to detect coolant-temperature gage, when leaving water temperature was lower than design temperature, the needed electrical heating power of control electrical heating module 7 outputs was to keep the constant of leaving water temperature.Use the heat pump ability of a release condenser unloading part like this by design, insufficient section is partly compensated by electrical heating, thereby guarantee the constant of leaving water temperature, when avoiding leaving water temperature too high, can reduce the operating load of unit, thereby greatly reduce the unit energy consumption, meet the requirement of national energy-saving and emission-reduction.
When 2) detecting leaving water temperature and be higher than design temperature, control electronic mixed water valve and open bypass line, cold water in the inlet pipeline is directly entered in the outlet pipeline through bypass line mixes with hot water, thus the temperature in the reduction outlet pipeline.By regulating the aperture of electronic mixed water valve, regulate the turnover ratio of heat pump water outlet and cold water, thereby also can reach the purpose of limit temperature.Judging that increasing the water yield can also guarantee under the situation of effluent temperature constancy, also can carry out bypass by electronic mixed water valve and mix water in addition, can make total water flow bigger like this, water will be more comfortable.
Further, because water tank volume is very little, consider under the low situation of environment temperature, water temperature descends very fast, for avoiding starting without regimen condition lower compression machine, the utility model also adopts a tinfoil paper heating tape 3 that water tank 4 outer surfaces are wrapped, tinfoil paper heating tape 3 is controlled by control module, judge whether the needs unlatching according to environment temperature and water tank temperature, this tinfoil paper heating tape 3 need 100～200W power, energy consumption is very low, can not exert an influence to the energy-saving effect of complete machine, increased the heat insulation effect of water tank, can not occur because of the not good problem that causes energy waste of heat insulation effect.Tinfoil paper heating tape itself has temperature controller in addition, can ensure that it uses safety.
Consult Fig. 3, second embodiment of the present utility model is similar to a last example structure, and difference only is not arrange electronic mixed water valve, except the corresponding control of having lacked electronic mixed water valve, other courses of work and principle are all identical with first embodiment, repeat no more herein.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
