With reference to fig. 1 and 3, therefore, when the first communication port 511 in the switching valve 5 is selected to communicate with the second communication port 512, it can be understood that the first communication port 511 does not communicate with the third communication port 513 at this time; when drying, heating blower 4 firstly extracts the air in the external atmosphere through second intercommunication mouth 512, let in washing chamber 31 after heating it, the clothing of hot-air in to washing chamber 31 is dried, when gaseous pressure reaches a definite value in making washing chamber 31 when letting in, if when reaching the default, the ooff valve of gas vent 7 department is opened, the gas that is mingled with humid air is direct to be discharged to the external world from gas vent 7 department, this is direct vent drying, this kind of drying method speed is very fast, the structure is comparatively simple, and the cost is lower.

With reference to fig. 5, in order to directly exhaust the gas into the external atmosphere, the exhaust port 7 may be further connected to an exhaust pipe 72, which is disposed in the box body 1, and one end of which is communicated with the atmosphere outside the box body 1 through an opening formed in the box body 1, and is used to directly exhaust the gas exhausted from the exhaust port 7 into the atmosphere.

The switch valve 71 may be a one-way piece, the one-way piece is rotatably disposed at the upper side of the exhaust port 7, and covers the exhaust port 7 by its own weight, and when the pressure in the washing chamber 31 reaches a preset value, the gas pushes the one-way piece to rotate, thereby opening the exhaust port 7.

Referring to fig. 2 and 4, when the first communication port 511 in the switching valve 5 selects to communicate with the third communication port 513, it can be understood that the first communication port 511 does not communicate with the second communication port 512 at this time; when drying is performed, the heating fan 4 firstly extracts gas in the washing chamber 31 through the third communicating port 513, the gas is heated by the heating fan 4 and then introduced into the washing chamber 31, the hot air contacts with clothes to form damp and hot air containing moisture, the damp and hot air enters the condensing pipe 6, the damp and hot air is condensed by the condensing pipe 6, liquid water formed by condensation of the damp and hot air flows back to a position between the inner drum 3 and the outer drum 2 and is discharged by a drainage system of the washing machine, the damp and hot air is relatively dry after passing through the condensing pipe 6 and is sucked by the heating fan 4 again, and then enters the washing chamber 31 to be circularly dried, so that condensation type drying is performed, and the drying mode has little influence on the outside because the damp air is not directly discharged to the outside.

It should be noted that a condensing device is provided in the condensing pipe 6 to condense the gas flowing therethrough. For example, in some embodiments, the condensation pipe 6 is provided with a nozzle which sprays water downwards, and further may be configured to spray water mist, after the wet and hot air comes out of the washing chamber 31 and enters the condensation pipe 6, the water mist sprayed from the nozzle exchanges heat with the wet and hot air flowing upwards, the temperature of the wet and hot air is reduced, the relative humidity reaches a saturated state, the contained moisture is condensed from a gas state to a liquid state and flows back to the space between the inner cylinder 3 and the outer cylinder 2 due to its own gravity, and the wet and hot air which separates out the moisture continuously flows upwards and is sucked into the heating fan 4, thereby completing the condensation type drying in a circulating manner.
