Detailed ways

In order to describe the technical content, structural features, achieved goals and effects of the present utility model in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

Component 5, electric heat assembly 3, controller assembly 4, water inlet pipeline 7, water terminal 8, hot water collector 9 and waste heat exchange device 10.

As shown in Figure 2, the thermal insulation water tank assembly 1 includes a shell composed of a water tank liner 19, a water tank shell 103, a water tank upper cover 18, a water tank lower cover 104 and a water tank foot 105, wherein the water tank shell 103 is sleeved in the water tank Outside the bladder 19, and between the two is filled with insulating foam 101 to insulate the water tank liner 19. The water tank liner 19 is made of enamel or stainless steel, which can withstand high pressure and corrosion. In order to prevent corrosion of the water tank liner 19, a magnesium rod 102 is fixedly arranged on the water tank liner 19, and the magnesium rod 102 extends into the inside of the water tank liner 19, and prevents corrosion of the water tank liner through the principle of sacrificial anode protection method, thereby prolonging the service life of the water tank Effect.

The inside of the water tank liner 19 is sequentially provided with a solar coil 106, a heating pipe, and a heating coil between the water outlet pipe head 17 and the water inlet pipe head 11 from top to bottom. Coil 14 and ground source coil 12. The solar coil 106 is connected to the vacuum tube solar assembly 6 to form a circulation passage, and utilizes the heat of the solar energy to circulate and heat the water in the water tank liner 19 .

The ground source coil 12 is connected to the ground source heat pump assembly 5, and the heat provided by the ground source heat pump assembly 5 is used to heat the water in the water tank liner 19. Since the vacuum tube solar energy assembly 3 can provide a relatively high temperature of the circulating working medium, the solar coil 106 is arranged on the upper layer of the water tank liner 19 to help ensure the total outlet water temperature of the water tank, and the ground source coil 12 is located in the water tank liner 19 In the lower part, the water temperature in this area is lower than that in the upper part of the water tank, so as to improve the operating efficiency of the ground source heat pump assembly 5 and reduce its operating load.
