1. A washer-dryer, characterized in that the washer-dryer comprises:
the inner barrel comprises a front barrel and a rear barrel, and clothes to be dried are placed in the front barrel;
the air inlet of the condensing air duct is connected to the rear barrel, and the air outlet of the condensing air duct is connected to the front barrel;
the fan is used for sucking air in the rear barrel into the condensing air duct through an air inlet of the condensing air duct and blowing the air into the front barrel through an air outlet of the condensing air duct so as to form air circulation; the heating device is used for heating the air in the condensing air duct;
the air suction device is arranged on the rear barrel and is used for sucking external cold air into the rear barrel when the temperature of the inner barrel reaches a preset first temperature threshold value, so that the wet and hot air in the rear barrel is cooled to separate out redundant water.
2. The washer-dryer of claim 1, wherein the one or more air suction devices are distributed at different positions of the rear tub.
3. The washer-dryer of claim 1 or 2, further comprising a one-way valve connected to an air outlet side of the air suction device for restricting a flow direction of air from the inner tub to the inner tub.
4. The dryer of claim 1, further comprising a water cooling device, wherein the water cooling device is used for spraying cold water to the outer side of the condensing air channel when the temperature of the inner barrel reaches a preset second temperature threshold value, so that the hot and humid air in the condensing air channel is cooled to separate out redundant water.
5. A condensation control method of a dryer, the dryer comprising an air suction device disposed on a rear tub, the method comprising:
when the dryer executes a drying operation, acquiring the temperature of an inner barrel of the dryer;
judging whether the temperature of the inner barrel reaches a preset first temperature threshold value or not;
if the temperature of the inner barrel reaches a preset first temperature threshold value, the air suction device is opened to enable cold air outside the inner barrel to flow into the rear barrel of the inner barrel, and wet and hot air in the rear barrel is cooled to separate out redundant water.
6. The method of claim 5, wherein the washer-dryer further comprises a water cooling device, the method further comprising:
judging whether the temperature of the inner barrel reaches a preset second temperature threshold value or not, wherein the second temperature threshold value is more than or equal to the first temperature threshold value;
if the temperature of the inner barrel reaches a preset second temperature threshold value, the water cooling device is opened, cold water is sprayed to the outer side of the condensation air duct, and the wet and hot air in the condensation air duct is cooled to separate out redundant water.
7. The method of claim 6, wherein after opening the suction device, the method further comprises:
and when the temperature of the inner barrel reaches a preset third temperature threshold, closing the air suction device and the water cooling device.
8. The method of claim 6, wherein after opening the suction device, the method further comprises:
judging whether a preset drying judging condition is reached;
if the preset drying judging condition is reached, the air suction device and the water cooling device are closed, and the drying operation is stopped.
9. The utility model provides a condensing control device of washing and drying machine, its characterized in that, washing and drying machine includes the device that induced drafts that sets up on the back bucket, the device includes:
the acquisition module is used for acquiring the temperature of the inner barrel of the dryer when the dryer executes drying operation;
the judging module is used for judging whether the temperature of the inner barrel reaches a preset first temperature threshold value or not;
and the control module is used for opening the air suction device if the temperature of the inner barrel reaches a preset first temperature threshold value so as to enable cold air outside the inner barrel to flow into the rear barrel of the inner barrel and enable the wet and hot air in the rear barrel to be cooled to separate out redundant moisture.
10. A computer readable storage medium, characterized in that the computer readable storage medium has stored therein a computer program, wherein the computer program is arranged to perform the steps of the method according to any of the claims 5-8 when run.
