Problems solved by technology
[0003] The heat released by the condenser 20 (heat exchange effect) is equal to the sum of the action of the compressor 21 and the heat absorbed by the evaporator 22 from the atmosphere (working temperature). In other words, the lower the atmospheric temperature, the less the heat released by the condenser 20, and the The time for the water liquid to be heated to the predetermined temperature will also increase. In addition, when the compressor 21 operates to pressurize and heat the refrigerant in the evaporator 22 into a high-temperature and high-pressure refrigerant vapor, the refrigerant vapor will have an appropriate pressure in the conduit (high-pressure pipe) , and the vapor pressure of the refrigerant in the conduit (high-pressure pipe) will vary proportionally to the atmospheric temperature (working temperature) where the compressor 21 and evaporator 22 are located. Therefore, the performance of the heat pump water heater will vary due to the temperature difference between summer and winter. It is different. In subtropical regions, the high temperature in summer can reach 30°C-33°C, and the lower temperature in winter can reach 12°C-9°C (or even lower). In an environment where the temperature difference between winter and summer is more than 20°C, the general heat pump water heater In low-temperature winter, its heating efficiency is poor, and users often have to wait for a long time before using hot water at a predetermined temperature
In addition, in the lower temperature working environment in winter, frost may form on the surface of the evaporator 22 due to the low temperature, resulting in poor performance

Embodiment Construction
[0024] Relevant technical means and structural features thereof for reaching creation purpose of the present invention, now coordinate the preferred embodiment shown in accompanying drawing, describe in detail as follows:
[0025] Please refer to Figures 3 and 4 at the same time, the present invention mainly includes a water heater body 30 and a heat pump unit 40; wherein:
[0026] The water heater body 30 can be filled with a filler having a thermal insulation effect, and a water inlet 31 and a water outlet 32 are arranged on it.
[0027] The heat pump unit 40 at least includes components such as a compressor 41, an evaporator 42, and a condenser 43. The condenser 43 can directly or indirectly heat the water in the water heater body 30. The condenser 43 communicates with the water heater through a conduit. The compressor 41 and the evaporator 42 outside the body 30 are connected; its main design is that the compressor 41 and the evaporator 42 of the heat pump unit 40 are co...

A structure of water heater with heat pump consists of hot water furnace with water inlet and outlet, heat pump set including compressor, evaporator and condenser. It is featured as connecting condenser in hot water furnace to compressor and evaporator at external of hot water furnace through guide pipe and packaging said compressor and evaporator in a sealed space.
Description
technical field [0001] The invention relates to a structure of a heat pump water heater, in particular to a structure for isolating the compressor and evaporator of the heat pump water heater from the outside, so that the isolated space where the compressor and evaporator are located can maintain a predetermined working temperature, and the heat pump water heater does not The structure of a heat pump water heater that varies in performance due to changes in atmospheric temperature. Furthermore, since the compressor absorbs the cold source emitted by the evaporator, it will not overheat during operation, thereby increasing the service life of the compressor. Background technique [0002] Due to the high risk of gas water heaters in use, it is often heard that users are poisoned or even killed. In view of this, some designers have devoted their efforts to the research and development of electric energy water heaters, and have electric energy that meets environmental protection...
