Background
The water heaters sold in the market at present are divided into four water heaters of gas, solar energy, air energy and electric energy according to different adopted energy sources. The first gas water heater has higher and higher use cost and certain potential safety hazard. The second kind of solar water heater is limited by the environmental climate and installation conditions. The third air energy water heater, also called heat pump water heater, also called air source water heater, is a device for producing hot water by absorbing heat from air by using the working principle of heat pump. The air can the water heater through letting the refrigerant constantly accomplish the thermodynamic cycle process of evaporation, compression, condensation, throttle and reevaporation, with the heat transfer in the environment to aquatic, it produces great noise. The fourth electric water heater generally adopts an electric bar heating mode, utilizes current to generate heat through a conductor, and heats liquid by means of an aluminum inner container or a stainless steel inner container. The efficiency depends on the heating efficiency of the heating plate, the heating plate mainly comprises a heating tube, an insulating isolation layer is added on the outer surface of the heating tube, a resistance wire is arranged in a metal tube, electrode ends are connected with two ends of the resistance wire, and in order to prevent the resistance wire from being contacted with the metal tube to cause electric leakage, a gap between the metal tube and the resistance wire is filled with magnesium oxide to form a heat conduction layer. Because the heating wire is small in size and is buried in the magnesium oxide powder with poor heat conduction effect, the heat generated by the resistance wire is accumulated on the resistance wire and is difficult to dissipate, and the energy efficiency is low; in addition, energy consumption loss occurs in the process of heating the inner container in heat transfer, so that the liquid heater has the phenomenon of low energy efficiency, in addition, the electric heating rod is easy to generate unsafe phenomenon of electric conduction in a watery environment, and can react with substances in water to form scale, so that the liquid heater cannot be cleaned, and when cold water is flushed in, the water temperature is rapidly reduced, so that a user can feel cold, and the number of people for bathing is limited by volume; the latter has high energy consumption, low water outlet temperature and insufficient electric capacity caused by ultrahigh current, is difficult to be accepted by common household users, and cannot be popularized and used.
