The liquid level sensor 30 is arranged with a high liquid level and a low liquid level in the wastewater collection box 23. When the wastewater liquid level reaches a high liquid level and the net heat unit 6 and / or the combustion heat unit 5 are working, the wastewater pump 24 works and guides the wastewater to the main drain port 27 through the one-way valve 25 and the water outlet solenoid valve 26 to participate in the circulation. When the wastewater liquid level drops to a low liquid level, the wastewater pump 24 stops working. The setting of the liquid level sensor 30 realizes the automatic treatment of wastewater by the wastewater treatment unit 7, improves the work efficiency and also avoids the possibility of requiring user operation and dirtying the customer's clothes. It can be understood that the height of the standard line of the high liquid level is not higher than the height of the overflow port 29, and the height of the standard line of the low liquid level is not lower than the connection point of the wastewater pump 24 at the wastewater collection box 23.
