In the first embodiment, by providing the first drainage channel 216 and the second drainage channel 226, when the drainage of the first drainage port 213 and the second drainage port 223 is overloaded, the overloaded inflow water is guided into the corresponding drainage structure 205 and is discharged through the corresponding drainage port, so that the water pressure borne by the inner wall of the corresponding flow channel structure 201 is reduced, and the situation that each flow channel structure 201 is broken is avoided.

Preferably, the first and second drain passages 216 and 226 are both slopes, such that the first drain port 213 slopes up toward the first drain port 217 and the second drain port 223 slopes up toward the second drain port 227; when the inflow water is under normal pressure, the inflow water only flows out through each flow channel structure 201 and is not divided by the corresponding drainage structure 205, so that sufficient inflow water is ensured to dissolve the additive in the additive cavity.

this embodiment is a supplement to the first and second embodiments described above, and has the following features:

drawer side walls 414 are respectively arranged at two sides of the detergent box 401, a drawer rear wall 415 is arranged at the rear side of the detergent box 401, and the upper edge of the drawer rear wall 415 is lower than the upper edges of the drawer side walls 414 and the drawer front wall 413, so that the drawer rear wall can be used for drainage; a vertical blocking groove 103 protruding towards the front side of the water box is arranged in the water box rear wall 102 in the containing cavity of the lower water box 3, and a gap for drainage is reserved between the drawer rear wall 415 and the water box rear wall 102 in the containing cavity through the blocking groove 103.

Preferably, the first and second drain ports 217 and 227 provided in the water box 2 are respectively provided at both sides of the blocking groove 103, so that the water flowing out from each drain structure 205 does not flow into the detergent box 401, but directly falls into the bottom of the box body 1 through a gap left between the drawer rear wall 415 and the water box rear wall 102 and is discharged, thereby reducing the water discharge pressure in the detergent box 401.

Embodiment four of example 2:

this embodiment is a supplement to the first to third embodiments, and has the following features:

a first water diversion plate 421 and a second water diversion plate 422 are correspondingly arranged above the first additive cavity 411 and the second additive cavity 412 respectively, and the first water diversion plate 421 and the second water diversion plate 422 are detachably mounted at the bottom of the water box 2 respectively; the first water diversion plate 421 and the second water diversion plate 422 are respectively full of drain holes; the sizes of the first water diversion plate 421 and the second water diversion plate 422 are adapted to the corresponding additive cavities.

The inlet water flowing down through the first and second drain openings 213 and 223 first falls into the first and second water diversion plates 421 and 422, respectively, and the first and second water diversion plates 421 and 422 can disperse the inlet water and respectively and uniformly flow into the corresponding additive cavities through the drain holes of the water diversion plates.

Preferably, a third water dividing plate 424 is respectively arranged at the top of each siphon cap 420; the third water distribution plates 424 are horizontally disposed, and the outer edge of each third water distribution plate 424 is located above the washing machine cavity. When the water flow speed entering the additive cavity is too high, the additive (especially the powdery additive) is carried away from the additive cavity and enters the drum of the washing machine without being completely dissolved by the inlet water, and in this case, the clothes are washed unevenly, even the additive is not completely dissolved after the washing machine performs the washing work and hangs on the clothes, and the user needs to wash again, which is very troublesome; in the embodiment, the inlet water is primarily dispersed through the drain holes of the first water distribution plate 421 and the second water distribution plate 422, and then falls on the corresponding third water distribution plate 424 for further dispersion and deceleration, so that the inlet water is gently washed away with the additives, the additives are uniformly dissolved in the inlet water, and then the inlet water is sent out through the siphon structure 417, thereby ensuring uniform cleaning of clothes, and avoiding the situation that the additives are not completely dissolved and stick to clothes; and the inflow water is scattered by the first water diversion plate 421 and the second water diversion plate 422 and then falls on the corresponding third water diversion plate 424, so that the impact on each third water diversion plate 424 can be reduced, the loss speed is reduced, and the whole service life of the water box is prolonged.

The embodiments in the above embodiments can be further combined or replaced, and the embodiments are only described in the preferred embodiments of the present invention, which are not limited to the concept and scope of the present invention, and various changes and modifications made by the technical solutions of the present invention by those skilled in the art without departing from the design concept of the present invention all belong to the protection scope of the present invention.
