The heat transfer structure according to claim 1, wherein a muffler is provided at an end of the high-temperature wastewater delivery pipe inserted into the wastewater containing space and/or an end of the clean water input pipe inserted into the clean water containing space; the silencer is a round pipe coaxial with the pipeline, and a plurality of silencing holes with the intervals of 70-90mm and the diameters of 4-6mm are formed in the surface of the round pipe.

7. The heat transfer structure of claim 1, wherein the purified water output pipeline is provided with a first variable frequency control pump and a first valve; and a second variable frequency control pump and a second valve are arranged on the wastewater return pipeline.

8. The heat transfer structure according to claim 1, further comprising:

and the hot water return pipeline is connected with the purified water accommodating space and is externally connected with the water using pipe so as to return unused hot water in the water using pipe to the purified water accommodating space.

9. The heat transfer structure of claim 1, further comprising a waste water return pipe connected to the waste water containing space and externally connected to a high temperature waste water generating device, so as to return the water with heat released and cooled in the waste water containing space to the high temperature waste water generating device.

10. The heat transfer structure of claim 1, wherein overflow holes are provided at the tops of the waste water-containing space and the purified water-containing space for allowing water to overflow when water in the waste water-containing space or the purified water-containing space is excessive.
