[0062] The hot flue gas after combustion by the first gas burner 15 enters the drum 12 through the flue gas channel 13, and the motor 16 drives the drum 12 to rotate so that the clothes are evenly exposed to the hot flue gas. The exhaust device 14 exhausts the hot flue gas in the drum 12 through the exhaust pipe 18;

[0063] After the clothes are dried, the drying mode is turned off on the operation panel, and the main control board 31 turns off the first control valve 171 and the motor 16 .

[0064] When hot water is needed, the hot water mode is selected on the operation panel, the hot water temperature is adjusted, the main control panel 31 turns on the motor 16, the second control valve 231 and the second gas burner 21 are ignited and started, and the first control valve 171 remains closed;

[0065] When a user turns on the faucet of the hot water pipe, the cold water is heated after passing through the heat exchanger 22 and flows out through the faucet of the hot water pipe for use by the user;
