According to the scheme, under the normal use state, the rotation stopping mechanism limits the rotation of the filter screen mechanism, the filter screen is fixed in the area where the water inlet position is located, and water enters from the water inlet mechanism and flows out from the communication port and enters into the water storage tank body after being filtered through the filter screen. When the filter screen needs to be cleaned, the rotation stopping mechanism is adjusted to enable the filter screen mechanism to recover the rotation capacity, the filter screen is turned over and reaches the area where the cleaning position is located, accumulated matters on the filter screen are downward at the moment, water flow is sprayed to the filter screen from top to bottom, the accumulated matters can be washed and fall off and reach a sewage disposal channel piece located below the filter screen at the moment, finally the accumulated matters are sent out of the phase-change energy storage water tank through the sewage disposal channel piece, and then the filter screen can be used normally again after being turned over again, so that the filter screen cleaning work is fast and effective, and the effective work efficiency of the phase-change energy storage water tank is improved.

The filter screen 32 is originally used for filtering in the water inlet position of the water inlet area 120a, and the first surface facing upwards generates accumulation and needs to be cleaned after the filter screen 32 is used, so the rotation stopping mechanism 7 is adjusted to enable the filter screen mechanism 3 to have a rotation degree of freedom, the filter screen mechanism 3 turns 180 degrees and then reaches the cleaning position, and the filter screen 32 reaches the position in the cleaning area 120b shown in fig. 2, so the first surface with accumulation faces downwards on the filter screen 32 which is turned 180 degrees and reaches the cleaning position. The water falling from the water receiving container 52 hits the filter screen 32, and the accumulated matter can fall onto the trapway member 41 and flow out of the water inlet tank 12 under the water flow.
According to the phase-change energy storage water tank, the filter screen is not required to be disassembled, the rotation stopping mechanism is adjusted to enable the filter screen to rotate from the water inlet area to the cleaning area, so that the filter screen can be washed and cleaned, and the cleaning work is rapid and effective; meanwhile, if two or more filter screens are arranged on the filter screen mechanism, the filter screens can be used for normal filtration and flushing at the same time in a water inlet area and a cleaning area in the water inlet tank body, so that the effective working efficiency of the phase-change energy storage water tank is effectively improved.
