Detailed ways

Below in conjunction with the embodiment shown in the accompanying drawings the utility model is further described.

As shown in Figure 1, a hybrid multi-purpose energy-saving water heater includes a water storage tank 12, a heat exchanger 7 installed in the water storage tank 12, an electric heating element 9, a temperature sensor 10, and the electric heating element 9 and temperature sensor 10. The sensor 10 is connected to a digital display temperature control switch 11 for controlling the two to work.

A dividing plate 13 is provided in the water storage tank, and the dividing plate 13 divides the water storage tank into a warm water chamber and a hot water chamber. The dividing plate 13 is respectively provided with a first opening 14 as a pipeline passage of the heat exchanger 7 and communicates with the warm water chamber and the hot water chamber. The second opening 15 of the hot water chamber, the warm water chamber is provided with at least one cold water inlet 1, at least one warm water outlet 3 and a heat medium inlet 2, and the hot water chamber is provided with at least one hot water outlet 5 and a heat medium The outlet 4, the electric heating element 9 and the temperature sensor 10 are all arranged in the hot water chamber.

Water storage tank 12 is divided into two chambers by dividing plate 13, respectively as the water storage tank room of warm water and the water storage tank room of hot water, has the second perforate 15 on the dividing plate 13 as the water inlet of hot water chamber, warm water chamber The water storage capacity allocation of the hot water chamber and the hot water chamber can be determined according to the user's water habits. A cold water inlet 1 is installed on the top of the warm water chamber, and a heating system heat medium inlet 2 is installed on the bottom, and both inlets are provided with manual valves. The top of the hot water chamber is equipped with a heating system heat medium outlet 4 and a hot water outlet 5 for bathing water, and the hot water outlet 5 is connected to a shower nozzle. The heat exchanger 7 is connected to the heating pipe through the heat medium inlet 2 and the heat medium outlet 4. The heat medium outlet 4 guides the heat exchanged heat medium into the heating system and returns to the heating company. The hot water in the heating pipe is heated by heat exchange into the water storage tank. of tap water. The heat exchanger 7 is made of copper tube and aluminum alloy, and has the characteristics of corrosion resistance, long life, large heat exchange area and high efficiency. In this embodiment, the heat exchanger 7 is a BR005 type plate heat exchanger with a single plate area of 170mm×500mm.

The tap water enters the warm water tank chamber through the cold water inlet 1, the heat medium provided by the heating system enters the heat exchanger 7 from the inlet 2, and the tap water is heated by the heat exchanger 7 to become warm water suitable for use.
