[0002] An electromagnetic dual-purpose heater / boiler is a heating and hot water supply device that combines electromagnetic heating technology. It heats flowing water through the heater using the principle of electromagnetic induction. When an electric current passes through the electromagnetic coil, an alternating magnetic field is generated, inducing a current in the metal pipes inside the heater, thus rapidly heating the water. This heating method is highly efficient and fast, with a thermal efficiency typically exceeding 98%.

[0003] A search revealed that the announcement number CN208887119U, entitled "A Condensing Gas-Fired Heating and Bathing Boiler," includes a burner, flue gas duct, main controller, main heat exchanger, plate heat exchanger, condensing heat exchanger, temperature sensor, electrically controlled valve, bypass pipe, and circulation pump. Research and analysis showed that it can ensure the temperature before entering the main heat exchanger is always maintained within a suitable range, preventing water vapor in the flue gas from condensing on the main heat exchanger, while also ensuring reasonable thermal efficiency. However, it still has the following drawbacks to some extent.

[0004] For example, it is not possible to select the appropriate mode according to the needs, the usage requirements of the device are different in winter and summer, it cannot guarantee the effective supply of hot water or hot water, the applicability is relatively general, the service life is short, and the furnace body is prone to shaking when installed on the wall, resulting in poor installation stability. In order to solve the above technical problems, we designed a variable frequency electromagnetic dual-purpose hot water heater. Utility Model Content

[0023] Please see Figure 4 and Figure 5 A power input cable 6 is fixedly installed on the top right side of the housing 1, and a dustproof net is fixedly installed on the top left side of the housing 1 and on the surface of the system fan 2. By setting the dustproof net, the system fan 2 can be protected from dust and dust can be prevented from entering the interior of the housing 1.

[0024] Please see Figure 4 and Figure 5 The input end of the three-way motor 8 is connected to the top of the heating tank 7 through a pipe, and the bottom of the heating tank 7 extends through to the bottom of the outer shell 1 and is connected to the drain valve 21.

[0025] Please see Figure 2 The two output ends of the three-way motor 8 are both connected to the bottom of the outer casing 1 and are provided with a heating water outlet 14 and a shower water outlet 15. A safety valve pressure relief outlet 16 is fixedly installed at the heating water outlet 14. By setting the heating water outlet 14 and the shower water outlet 15, hot water can be discharged in two parts, and different modes of water supply can be provided according to demand, so as to achieve the effect of rational use of water source and energy saving.

[0026] Please see Figure 2 The output end of the circulation pump 10 is connected to the heating tank 7 through a pipe. The drain end of the circulation pump 10 is connected to the bottom of the outer shell 1 through a pipe and is provided with a pump outlet 18.

[0029] During use, tap water enters the heating tank 7 through the tap water inlet 17, heats the water inside the tank, and then discharges it through the drain valve 21. In summer, when heating is not required, switch to summer mode. In this mode, only showering is possible, and heating is not available. When the shower faucet is turned on, the machine automatically enters shower mode and supplies hot water. In winter, when heating is required, switch to winter mode. This mode provides both heating and showering. When the shower faucet is turned on, hot water is discharged from the shower outlet 15. The machine automatically turns off the heating in shower mode and supplies hot water. When the outlet water temperature is ≤8℃ and >5℃, it automatically enters antifreeze mode 1. In antifreeze mode 1, the circulation pump runs for 2 minutes and stops for 2 minutes, but heating is not started. It automatically exits antifreeze mode 1 when the outlet water temperature is ≥10℃. When the outlet water temperature is ≤5℃ and >1℃, it automatically enters antifreeze mode 2. In antifreeze mode 2, the circulation pump 10 runs continuously and heating is started. It automatically exits antifreeze mode 2 when the outlet water temperature is ≥30℃.
