Abstract

The utility model provides a water heater of an air source heat pump, which comprises a compressor, a water tank heat exchange pipe coil, a throttling component, an evaporator, an air auxiliary electric heater, a water tank inner container and a casing, wherein the compressor, the water tank heat exchange pipe coil, the throttling component, the evaporator, the air auxiliary electric heater and the water tank inner container are mounted in the casing; the water tank heat exchange pipe coil is clung to on the outer wall of the water tank inner container; the compressor, the evaporator, the throttling component and the water tank heat exchange pipe coil are connected in sequence; and the water heater is characterized in that the air auxiliary electric heater is mounted on the windward side or the leeward side of the evaporator. The utility model adopts the structure that the air auxiliary electric heater is mounted on the windward side or the leeward side of the evaporator, thereby increasing the air outlet temperature of the water heater, avoiding cold wind blown to the indoors, upgrading the heating capability at low temperature, and solving the problem of defrosting; and meanwhile, the electric heater is not in contact with fins of the evaporator, so that water and electricity can be separated and safety is greatly improved.

Description

A kind of air source hot pump water heater
Technical field
The utility model is a kind of air source hot pump water heater, particularly a kind ofly is installed in indoor air source hot pump water heater.
Background technology
Existing air source hot pump water heater can discharge cold air when working, indoorly then can reduce indoor temperature if be installed on, cold wind can allow the people feel uncomfortable in the time of in the winter time, and air source hot pump water heater heating capacity when low ambient temperature is significantly decayed, its evaporimeter also can frosting, and for remedying above-mentioned defective, some producers can adopt at the inner electric heater unit of installing of water tank heats, but exist energy efficiency not high, and water power contact problems such as electric shock easily; Also have some producers that electric heating tube is placed in the evaporator fin, also there is the risk of electric heating tube electric leakage in this structure, and increases the volume of evaporimeter; Also have some producers that special-purpose heater is set on the connecting line between compressor and the evaporimeter, the shortcoming of doing like this is the direct heating and cooling agent of electric heater, cause the rotten of cold-producing medium and lubricating oil easily, the infringement refrigeration system shortens the refrigeration system life-span.
The utility model content
The purpose of this utility model is to overcome the prior art defective and a kind of safe and reliable air source hot pump water heater is provided.
The technical solution of the utility model is: a kind of air source hot pump water heater, comprise compressor, water tank heat exchange coil, throttle part, evaporimeter, air electrical auxiliary heater, inner water tank and shell, wherein compressor, water tank heat exchange coil, throttle part, evaporimeter, air electrical auxiliary heater and inner water tank are installed in the enclosure, the water tank heat exchange coil is close on the outer wall of inner water tank, compressor, evaporimeter, throttle part and water tank heat exchange coil connect successively, it is characterized in that the air electrical auxiliary heater is installed in the windward side or the leeward side of evaporimeter.
Blower fan also is housed in the above-mentioned shell, and blower fan is installed in a side of evaporimeter.
The utility model is owing to adopt the structure that the air electrical auxiliary heater is installed in the windward side or the leeward side of evaporimeter, not only improved the leaving air temp of water heater, avoid to blows cold wind indoors, also can when low temperature, promote heating capacity, solve the defrosting problem, electric heater does not contact with water tank and evaporator fin simultaneously, thereby reaches electricity separation, has improved security greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples the present invention is further described.
Referring to Fig. 1, the utility model air source hot pump water heater, comprise compressor 1, water tank heat exchange coil 2, throttle part 3, evaporimeter 4, air electrical auxiliary heater 5, inner water tank 6, blower fan 7 and shell 8, wherein compressor 1, water tank heat exchange coil 2, throttle part 3, evaporimeter 4, air electrical auxiliary heater 5, inner water tank 6 and blower fan 7 are installed in the shell 8, water tank heat exchange coil 2 is close on the outer wall of inner water tank 6, compressor 1, evaporimeter 4, throttle part 3 and water tank heat exchange coil 2 connect successively, blower fan 7 is installed in the top of compressor 1, one side of evaporimeter 4, air electrical auxiliary heater 5 are installed in the windward side or the leeward side of evaporimeter 4.In the present embodiment, air electrical auxiliary heater 5 is installed in the windward side of evaporimeter 4.
The utility model is because the air heat that the air electrical auxiliary heater will enter evaporimeter, can improve the leaving air temp of water heater, not to blows cold wind indoors, improve evaporating temperature, effectively improved evaporation effect, improved the cycle efficieny of heat pump, solve the problem of low temperature ability decay, solved the problem that frosting and defrosting cause system effectiveness to descend simultaneously, realized electricity separation, security is promoted greatly.
