Embodiment 1

[0040] Figure 4 It is a structural schematic diagram of Embodiment 1 of the debris filtering device of the present invention.

[0041] As shown in the figure, the dust filter device of the washing and drying machine according to the present invention is composed of a positioning and holding slide rail frame 30 and a dust filter net frame 40, and the positioning and holding slide rail frame 30 is fixed on the The above-mentioned air duct is close to the hot air outlet 17. In order to effectively filter out the dander in the air duct, the described positioning and clamping slide rail frame 30 traverses the entire air duct section; Slidingly disposed in the positioning and holding slide rail frame 30 .

[0042] Wherein said positioning and clamping slide rail frame 30 is a rectangular frame formed by a front panel 31, left and right side frames 32, 33 and a bottom frame 34. The insertion opening 35, the left and right side frames are provided with plane slide rails 36, and the...

Embodiment 2

[0046] Figure 5 It is a structural schematic diagram of Embodiment 2 of the debris filtering device of the present invention. Embodiment 2 is a change to the clamping device on the basis of Embodiment 1. The clamping hole and the clamping block on the side frame are canceled, and the clamping device is arranged in the guide post and the guide insertion hole. Specifically, an elastic card 39 is provided in the guide socket 37' of the bottom frame of the positioning and holding slide rail frame, and an elastic card 39 is provided on both sides of the guide column 46 on the bottom frame of the filter dust screen frame. There is a positioning groove 51, and when the filter debris screen frame 40 is inserted into the positioning and clamping slide rail frame 30, the elastic card 39 in the guide hole of the bottom frame of the positioning clamping slide rail frame clamps the guide guide column on the bottom frame of the filter debris screen frame The positioning grooves 51 on both...

Embodiment 3

[0048] Fig. 6 is a schematic structural view of Embodiment 3 of the debris filtering device of the present invention.

[0049] In the dust filter device of the washing machine shown in Figure 6, the positioning and holding slide rail frame 60 is also a rectangular frame composed of a front panel, left and right side frames and a bottom frame, and the front panel There is an insertion port for inserting the dust filter frame on the top. The difference is that slide grooves 61 are provided on the left and right side frames 60, and the plane slide rails in Embodiment 1 are replaced by slide grooves 61; There is a rectangular frame with front frame plate, left and right side frame 62 and bottom frame that the insertion port of rail frame inserts, and its left and right side frame 62 is provided with on the left and right side frame of clamping slide rail frame along the positioning The sliding block 63 that slides in the chute 61; the filter debris screen frame is inserted from t...
