Referring to fig. 1-4, the present invention provides a technical solution:

the utility model provides a heat recovery utilizes device of warm logical air conditioner, includes

water tank

1, and 1 left side top surface of water tank is connected with inlet tube 2, is the horizontal structure in the inlet tube 2 and is equipped with pivot A3, has cup jointed impeller 4 on the pivot A3, and the valve 5 that drains is installed to 1 lower extreme outer wall of water tank, and 1 inside vertical structure that is of water tank is equipped with pivot B6, has cup jointed paddle wheel 7 on the pivot B6, and the paddle wheel 7 is the central symmetry structure in the lower extreme outside and is equipped with two heat exchange assemblies 8.

Specifically, the water inlet pipe 2 is of a hollow rectangular structure. The design is inlet tube 2 of hollow rectangle structure, and its aim at is convenient for install impeller 4 for when adding water, cold water impact impeller 4, and then make impeller 4 drive pivot A3.

Further, the right end of the rotating shaft A3 passes through the inner wall of the water inlet pipe 2 and extends to the outside and is sleeved with a bevel gear A301.

Furthermore, the upper end of the rotating shaft B6 passes through the top surface of the inner side of the water tank 1 to extend to the outside and is sleeved with a bevel gear B601, and the bevel gear B601 is in meshing transmission with the bevel gear A301. Through the meshing transmission of bevel gear B601 and bevel gear A301 for the potential energy of cold water impact converts the pivoted kinetic energy of pivot B6 into, and then makes paddle wheel 7 rotate in water tank 1, stirs the cold water that adds, makes cold water and the even mild of hot water in the water tank 1, thereby improves the efficiency of cold water heat transfer.

It should be noted that the heat exchange assembly 8 includes a heat exchange plate 801 welded to the inner wall of the water tank 1, the heat exchange plate 801 is a semicircular structure, and a heat exchange cavity 802 is formed in the heat exchange plate 801.
