After the water tank 31 is filled with water, a user pushes the water tank 31 into the water tank seat 32, the rear end of the water tank 31 contacts with the lower baffle plate 53, the rear end of the lower baffle plate 53 is driven to overcome the gravity of each counterweight 6 and turn downwards under the assistance of the pushing force, the lower baffle plate exerts downward pulling force on the left baffle plate 51 and the right baffle plate 52 again, the left baffle plate 51 and the right baffle plate 52 are screwed out of the slots 321 respectively, when the left baffle plate 51 and the right baffle plate 52 are screwed out of the slots 321 completely and positioned, the lower baffle plate 53 is restored to an initial state (namely a horizontal state), and at the moment, the water tank 31 can be pushed into the water tank seat 32 smoothly. Therefore, the water tank assembly 3 is simple in structure, high in stability and free of influence of high-temperature cooking environment.
