Background technique
Currently, common heat pump water-heating machine is divided into circulation hot water dispenser and directly-heated type hot water machine, these two types of heat pump water-heating machines exist
It is had the following problems respectively when heating water:
(1) circulation hot pump hot water machine enters heat pump unit by the cold water of constantly extraction water pot bottom and is heated, and passes through
Hot water after heat pump is entered at the top of water pot by outlet pipeline, and the water that user is extracted at the top of water pot in water pot makes
With；But the hot water after heat pump can be such that the temperature of hot water reduces after entering water pot with the cold water mix of water pot bottom,
The demand temperature of user is not achieved；Therefore, such circulation hot pump hot water machine, which is generally required, carries out multiple circulating-heating to water, when
When the water temperature of water reaches the demand temperature of user in water pot, user just can use hot water with big flow；But user not
Disconnected big flow, if water shortage in water pot, water (generally tap water) will be injected at the top of water pot and will be given using during hot water
Water pot moisturizing can thus make the water temperature at the top of water pot reduce, and because heating speed of the circulation hot water dispenser to water is slower, when
After injection water is to water pot moisturizing at the top of water pot, the temperature of user demand is unable to reach in the temperature short time of the water at the top of water pot,
It will affect the usage experience of user in this way；
(2) direct-heating heat pump water heater by constantly carried out in heat pump unit heating water reach user demand water temperature after,
User terminal, which can be flowed directly into, allows user to use；But the hot water flow of such direct-heating heat pump water heater is smaller, is not able to satisfy use
The demand of family water use peak phase big flow water.
