A fan for facilitating circular air flow in the laundry accommodating space and the drying air passage, a heating device for heating air, and a condensing device for condensing wet air from the laundry accommodating space are disposed in the passage. A sensor for detecting parameters, such as temperature or humidity, of circulated air is generally further disposed in the drying air passage, with a head of the sensor being exposed to drying air. Therefore, when the drying air passes through the position where the sensor is located, hair, fluff from laundry, and other sweeps carried by the drying air are easily adhered to the sensor. In the long run, the accumulation of the adhered matters will cause serious influence on accuracy of the detection result of the sensor, thereby affecting control of the laundry drying apparatus.

For example, in a simple drying apparatus, if a drying manner without water is adopted, that is, no condensate water is sprayed for condensation, there will be a large amount of adhered matters on the sensor. In a drying apparatus adopting water condensation, in order to prevent the condensate water from affecting the accuracy of the detection result, the sensor is generally disposed at a position where the sensor does not contact the condensate water, so the condensate water does not rinse the sensor. In some cloths washing and drying apparatuses, the sensor is immerged in washing water during cloths washing and the adhered matters can be brought away by the washing water, but foam left after cloths washing may cover the sensor. Furthermore, when a user use the washing and drying machine not to perform a washing operation but only to perform a drying operation for a long time, the adhered matters on the sensor also cannot be washed away.

3 is mounted in the box 2. A rotary drum 4 is rotatably mounted in the water barrel 3 or tub 3. The rotary drum 4 is disposed with through holes (not shown), so as to be in spatial communication with the water barrel 3, to allow exchange of liquid between within and without the drum 4. Laundry to be processed is placed into the rotary drum 4 through a door component 5 mounted on the box 2, and is washed and/or dried in the rotary drum 4.
The water barrel 3 is connected to two ends of a drying air passage 6 respectively. Air for drying the laundry circularly flows in a space formed by the water barrel 3 and the drying air passage 6.

A control device 22 controls the washing and drying machine 1 according to a detection result of the detection device 10. In a specific implementation shown in FIG. 1 , the detection device 10 is disposed near an inlet of the air condensing passage 7. The detection device 10 has a head 1 1 extending into the drying air passage 6. A cleaning device 12 for rinsing the head 1 1 of the detection device is mounted close to the detection device. The cleaning device 12 includes a water introduction passage 13 and a rinsing device 14 mounted on one end of the water introduction passage 13. A spraying device 15 for rinsing the air condensing passage 7 is disposed on the air condensing passage 7. The spraying device 15 has an inlet pipe 16. The other end of the water introduction passage 13 of the cleaning device 12 is in communication with the inlet pipe 16 of the spraying device 15. An upstream of the water introduction passage 13 of the cleaning device and the inlet pipe 16 of the spraying device is connected to an anti-backflow device 17, and is further connected to an inlet valve 18 through the anti-backflow device 17.
As shown in FIG. 2, the rinsing device 14 and a wall 23 of the drying air passage 6 are integrally formed, the rinsing device 14 has a ring-shaped passage 19 disposed around the head 1 1 of the detection device, and a water outlet 20 is disposed on a bottom of the ring-shaped passage 19.
