As an independent component and fixed on the water collecting device 420, the water collecting groove 421 is easy to process, and is particularly beneficial to cleaning and maintaining the water collecting groove 421 in the later period when the water collecting groove 421 is detachably and fixedly connected with the water collecting device 420.
The water receiving groove 421 and the water collecting device 420 may be welded, screwed, riveted or plugged.
As another alternative in this embodiment, the water receiving groove 421 is a circumferentially surrounding groove (not shown) formed on the bottom wall 425 of the water collecting device. The existing structure of the water collecting device 420 is directly utilized, the groove is directly formed in the bottom wall 425, the structure is simple, and the processing is convenient.
As shown in fig. 9, the water collecting device 420 further includes a water collecting device drain opening 424 formed in a side wall 422 of the water collecting device located at a lower portion of the inner tub 410. The side wall between the outer edge of the water collecting device water outlet 424 and the water receiving groove 421 and the side wall between the outer edge of the water collecting device water outlet 424 and the outer edge of the side wall 422 of the water collecting device are both obliquely arranged, and the water collecting device water outlet 424 is positioned at the lowest position of the oblique side walls. This setting makes the inner tube discharge water flow that gets into in water receiving recess 421 under the effect of gravity, and edge slope lateral wall 422 that can be quick gets into water collecting device outlet 424, has avoided discharge water flow to be detained the siltation in lateral wall 422, forms the caking, pollutes the drainage environment and blocks the outlet even.
As shown in fig. 9, the further water collecting device 420 further includes a water blocking ring 423 annularly disposed on an outer edge of a sidewall 422 of the water collecting device. The side wall between the outer edge of the water collecting device water outlet 424 and the water receiving groove 421 and the side wall between the outer edge of the water collecting device water outlet 424 and the water retaining ring 423 are both obliquely arranged, and the water collecting device water outlet 424 is positioned at the lowest position of the oblique side wall. The water retaining ring 423 prevents the discharged water flow of the inner drum 410 from flowing to the outside of the water collecting device 420 along the sidewall 422, thereby polluting the environment inside the washing machine.
As shown in fig. 9, in order to conveniently guide the discharged water in the inner tub 410 to the water receiving groove 421, the washing machine in this embodiment includes a water outlet guide structure 414. The water outlet guiding structure 414 is communicated with the inner cylinder 410 and guides the water outlet flow of the inner cylinder, and the water outlet end of the water outlet guiding structure 414 extends into the water receiving groove 421.
The specific arrangement of the water outlet guiding structure 414 is described in detail in the first and second embodiments, and is not described herein again.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and although the present invention has been disclosed with reference to the above preferred embodiment, but not to limit the present invention, any person skilled in the art can make modifications or changes to equivalent embodiments by utilizing the above technical contents without departing from the scope of the present invention, and any simple modification, equivalent change and modification made to the above embodiments by the technical matters of the present invention are within the scope of the present invention.
