But the carbon dioxide heat pump water heater in the prior art, since the temperature that it can reach is higher so that its It needs to adjust it into trip temperature in domestic processes, during relative adjustment, user is needed ceaselessly to try temperature, to ensure that temperature is fitted Preferably.On the one hand, the water during examination temperature is continuously let go, and causes the waste at water source；On the other hand, due to temperature adjustment process It is more difficult to control, easily so that water is sometimes hot and sometimes cold, influence user experience.
Utility model content
In view of the deficiencies of the prior art, the utility model provides a kind of carbon dioxide heat pump water heater.
To achieve the above object, the utility model provides following technical solution：A kind of carbon dioxide heat pump water heater, packet Evaporator, compressor, heat exchanger and expander are included, feed pipe and hot-water line are connected on heat exchanger, heat is connected on hot-water line Water storage tank is provided with outlet pipe on hot water storage tank, temperature adjustment storage tank is provided on the outlet pipe, is provided on the temperature adjustment storage tank It is described with temperature sensor, control centre and three-way magnetic valve is provided on water pipe with water pipe, it is connected on the three-way magnetic valve There is return duct, the return duct is connected with temperature adjustment storage tank, and the branch pipe of connection temperature adjustment storage tank, the branch are provided on the feed pipe Cold water solenoid valve is provided between pipe and temperature adjustment storage tank, the cold water solenoid valve is electrically connected with control centre.
Through the above technical solutions, starting the water heater, the hot water in hot water storage tank is flowed into from hot-water line in temperature adjustment storage tank, Since the water of front end is colder, when which flows out by using water pipe, since temperature sensor is unsatisfactory for the temperature of control centre's setting Degree, three-way magnetic valve can will be closed with water pipe and open return duct, so as to which the Duan Shuihui is back to from return duct in temperature adjustment storage tank； When hot water storage tank persistently conveys hot water to temperature adjustment storage tank, the water temperature in temperature adjustment storage tank may be excessively high, when temperature sensor detects To in water pipe when the temperature is excessively high, since control centre is electrically connected with cold water solenoid valve, cold water solenoid valve can be controlled to open, from And to be reduced with the water temperature in water pipe, when the water temperature at this is adjusted to set temperature, control centre's control threeway electromagnetism Valve closing volume pipe and open with water pipe, increase the purpose of user experience simultaneously so as to fulfill water resource is saved.
It is further arranged to, hot water electromagnetic valve, the hot water electromagnetism is provided between the temperature adjustment storage tank and hot water storage tank Valve is electrically connected with control centre.
Through the above technical solutions, the setting of hot water electromagnetic valve enables to the hot water between hot water storage tank and temperature adjustment storage tank Flowing is controlled by control centre, to prevent hot water storage tank from carrying out continuing water delivery between temperature adjustment storage tank, is prevented in temperature adjustment storage tank Water temperature over-high.
It is further arranged to, timer is provided on the temperature adjustment storage tank, the timer is electrically connected with control centre.
Through the above technical solutions, timer can be used for timing, it is used for giving control centre one at interval of certain time A electric signal so that control centre control hot water electromagnetic valve opens carries out temperature-compensating to temperature adjustment storage tank.
It is further arranged to, blender is provided in the temperature adjustment storage tank.
Through the above technical solutions, blender rotates in temperature adjustment storage tank, hot water and cold water can be sufficiently stirred, So that the thermometric of temperature sensor is more accurate.
