The heat exchange assembly plays a role in heat exchange between the liner assembly 1 and the water tank 2, and water in the water tank 2 is preheated by waste heat in the liner assembly 1, so that the energy consumption of subsequent heating is reduced.
Specifically, a water outlet hole 22 is arranged at the bottom of the water tank 2, a water inlet hole 21 is arranged at the upper part of the water tank, water in the water tank 2 is input from the water inlet hole 21, and the water outlet hole 22 is output, so that the circulation and the transportation of the water are realized. The water inlet end of the water pump 4 is connected with the water outlet hole 22, and the water outlet end of the water pump 4 is connected with the liner assembly 1 through the water supply pipe 3, so that water supply communication between the vertical direction and the liner assembly 1 is realized.
