and the switch control unit is used for controlling the on/off of the automatic hot water discharge pipeline according to the switching instruction of the control unit.
6. An automatic drain hot water system according to claim 4, wherein: the waste water output pipeline is provided with a concentrated water throttling device, and the concentrated water throttling device is arranged between a connecting node of the hot water discharge pipeline and the waste water output pipeline and the water purifying unit;
the pipeline water pressure in front of the concentrated water throttling device is P 1 The pipeline water pressure behind the concentrated water throttling device is P 2 The pipeline water pressure of the hot water discharge pipeline is P 3 The thick water throttling device is used for enabling the water pressure in the pipeline to meet P 1 ＞P 3 ＞P 2 。
7. An automatic water evacuation system according to any one of claims 1 to 6, wherein: the hot water discharge pipeline is a U-shaped pipe.
8. A hot water discharge method based on an automatic draining hot water system according to any one of claims 1 to 7, characterized in that it comprises the steps of: when a preset condition is met, the control unit sends out a hot water emptying instruction, the pump body receives the hot water emptying instruction, and hot water in the heating unit is discharged;
the preset conditions include:
when a preset time period is met, the control unit automatically sends out the emptying hot water instruction; or alternatively
When a remote control instruction is received, the control unit sends out the emptying hot water instruction; or alternatively
When the drainage control key is triggered, the control unit sends out the hot water draining instruction.
9. The hot water discharge method according to claim 8, wherein the evacuating-hot water system is provided with a hot water switching unit and a waste water output line;
the preset condition comprises a hot water draining step when no person is on duty, and the hot water draining step comprises the following steps: the control unit detects the temperature of the hot water in the heating unit, and when the control unit detects that the temperature of the hot water discharged into the waste water output pipeline in the heating unit exceeds a preset threshold value, a control signal is sent to the water purifying unit, so that the water purifying unit enters a normal water making process, and waste water generated in the normal water making process is mixed with the hot water in the hot water discharge pipeline through the waste water discharge pipeline.
10. The hot water discharge method according to claim 8, wherein the evacuating-hot water system is provided with a hot water switching unit, a waste water output line and a hot water outlet tap;
the preset condition includes a hot water discharging step when hot water is normally used, the hot water discharging step including: the control unit detects the heating unit, and when the hot water in the heating unit is detected to be emptied, the hot water switching unit is switched, so that a circuit breaking state is formed between the hot water discharge pipeline and the waste water output pipeline, and meanwhile, the hot water discharge pipeline and the hot water outlet faucet are kept in a communicating state, so that hot water in the heating unit can be discharged from the hot water outlet faucet.
