[0022] Example: Figure 1-4 The present invention provides a technical solution: including a base 3, a recycling bin 4 and an inner liner 12.

A heat pump heat output pipe 6 is installed at the bottom right end of the recycling bin 4, and a control valve 7 is installed on the heat pump heat output pipe 6.
[0023] An inner liner 12 is installed inside the recycling bin 4. An inner cavity 11 is provided between the inner liner 12 and the four end faces of the recycling bin 4. It is located at the left end of the heat output pipe 6 of the heat pump and is connected to the inlet of the heat transfer pipe 13 through a connector 14. The heat transfer pipe 13 forms a spiral winding structure around the inner liner 12 and extends to the bottom of the inner liner 12.
[0024] An embedded temperature display screen 5 is provided on the front left side of the recycling bin 4. The temperature display screen 5 is electrically connected to the temperature sensor 16 at the rear end of the inner liner 12. A water inlet 8 is provided at the center of the upper end of the recycling bin 4, and a water valve 15 is provided at the bottom of the left end of the recycling bin 4, which is connected to the inner liner 12.
[0025] The heat transfer pipe 13 has a ring structure at the bottom inside the inner liner 12, and the heat outlet 17 of the heat transfer pipe 13 is located at the lower end inside the inner liner 12, which can maximize the heating of water.
[0026] The exhaust port 9 located on the upper right side of the recycling bin 4 is connected to the inner liner 12, allowing gas to be discharged through the exhaust port and balancing the air pressure between the inner liner and the outside.
[0027] The upper left side of the recycling tank 4 is equipped with a sliding liquid level float 10, and the bottom of the liquid level float 10 is inside the inner tank 12. The liquid level height inside the inner tank can be known through the hydraulic float.

[0029] A rectangular connecting plate 2 is welded between the two support legs 1 to increase the stability of the recycling bin.
[0030] Working principle:
[0031] In use, the heat generated by the air heat pump is connected to the heat transfer pipe 13, and water is injected into the inner tank 12 through the water inlet 8. The water level in the inner tank 12 is observed according to the level float 10. Then, the control valve 7 is opened, and the heat is recovered to the heat transfer pipe 6. The temperature is transferred through the heat transfer pipe 6 and discharged through the heat outlet 17. While the heat is being transferred in the heat transfer pipe 6, the water in the inner tank 12 is heated. At the same time, the heat transfer pipe 13 in the inner tank 12 also heats the water. The heat is discharged through the heat outlet 17, directly heating the water, which can maximize the heating of the water and make the heat recovery and utilization more efficient. During the heating process of the water in the inner tank 12, the temperature sensor 16 detects the water temperature in the inner tank 12 and transmits it to the temperature display screen 5 through the controller, so that the water temperature in the inner tank 12 can be observed intuitively. The gas generated when heating the water in the inner tank 12 is discharged through the exhaust port 9. When warm water is needed, it can be discharged through the water valve 15.
