Description

    BACKGROUND OF THE INVENTION
  • The utility model relates to a water heater, especially relates to an air source instant water heater.
  • The instant water heaters in the prior art all use electrical power as power source, and heat cold water by big electrical heating devices to preset high temperature water in short time, requiring vast electrical power. And because the temperature difference of water flow before and after heated is relatively big, it also has relatively great influence to life span of heater. As a new type domestic facility, water source heater can effectively save power source. But the heating speed of water source heater to water is slow, and the waiting time after open is long, and the highest heating temperature is greatly related with working substance properties used by air source heating device and outside environment temperature, and can not usually reach the high temperature needed by users.
    • BRIEF SUMMARY OF THE INVENTION
  • The purpose of the utility model is to provide an air source instant water heater with energy conversation and high efficiency.
  • For the above purpose, the utility model includes instant electrical heating device, on which mounted a water inlet pipe and a water outlet pipe. The hot water outlet of an air source heating device is connected with the water inlet pipe of the instant electrical heating device, and the cold water inlet of the air source heating device is connected with a tap water pipe. When it is used by users, water is first heated by air source heating device to certain temperature and then heated to higher temperature by instant electrical heating device, which meets the using requirement of users and saves energy at the same time.
  • Air source heating device of the utility model includes air flow system, working substance circular system and water flow pipeline system. The air flow system includes an air inlet port which sucks air in, exhaust port which exhausts air, and tube-axial fan for driving air flow. The working substance circular system includes condenser mounted at air inlet port and evaporator mounted at air exhaust port. The first pathway and the second pathway are set between the condenser and the evaporator. The working substance in the working substance circular system flows from evaporator to condenser through the first pathway, and a compressor is connected on the first pathway. The working substance flows from condenser to evaporator through the second pathway, and an expansion valve is connected on the second pathway. The working substance in the working substance circular system circularly flows between condenser and evaporator. The water flow pipeline system includes sequentially connected cold water inlet, heat exchange pipeline and hot water outlet. The cold water inlet is connected with tap water pipe, and hot water outlet is connected with water inlet pipe of instant electrical heating device. The heat exchange pipeline is contact with the condenser of the working substance circular system, and the water in water flow pipeline system exchanges heat with the working substance in working substance circular system.
  • When the tube-axial fan begins to operate, air outside is sucked into air source heating device from air inlet port, and exchanges heat with the evaporator. Air whose temperature is lowered is exhausted out of air source heating device from exhaust port by driven of tube-axial fan. Meanwhile, working substance in the evaporator absorbs heat, vaporizes and is sucked into compressor. The compressor compresses this kind of low-pressure working substance gas to working substance gas with high temperature and high pressure which is sent to condenser and liquefied with heat released in condenser. The released heat is transmitted to water in water flow pipeline system, at this time water in water flow pipeline system is heated and working substance gas is cooled and liquefied to working substance liquid. The working substance liquid flows into evaporator again after throttled and cooled by expansion valve. Air source heating device heats cold water by repeating the above circulation constantly.
  • On the pipeline between water inlet pipe and water outlet pipe of the instant electrical heating device there is set a water flow activated valve. The water flow activated valve can sense the flow of water in pipeline, thus activating air source heating device and instant electrical heating device in time to heat the water.
  • In conclusion, compared with prior art, the utility model first uses air source heating device to improve water temperature, and then uses instant electrical heating device to heat water rapidly to desired temperature of user, thus not only saving electrical power but also meeting the using requirement of users.
