Because the water quantity of the detergent siphon cavity is larger than that of the softener siphon cavity, a larger drainage cavity is arranged in the detergent siphon cavity. Meanwhile, in order to increase the drainage speed of the first drainage cavity 2381 at the side of the detergent siphon cavity, the bottom of the detergent box at the detergent siphon cavity is obliquely arranged and is obliquely and downwards arranged from the outer side to the inner side, so that the space at one side between the outer bottom surface of the detergent box and the inner bottom surface of the box body is larger, and the drainage function of the first drainage cavity 2381 is increased.

In other embodiments, the number, location, and size of the drain cavities 238 are not particularly limited.

In this embodiment, the rib 239, the partition 236 and the detergent box 230 are integrally formed, the detergent box 230 includes a detergent box cover 231 and a detergent box 232, and the detergent box cover 231, the detergent box 232 and the partition 236 are connected by welding to prevent water from overflowing from the upper side.

In order to further improve the drainage effect, the drainage cavity 238 is located below the water diversion plate 220, a part of water flowing out from the water leakage hole of the water diversion plate 220 directly flows into the drainage cavity 238 and does not enter the siphon cavity 237, i.e. a part of water flowing down from the water diversion plate 220 enters the siphon cavity 237 and a part of water flows into the drainage cavity 238, as shown by the arrow in fig. 10, the water flows in the direction shown by the arrow, when the water amount is too high, the water can firstly pass through the drainage cavity 238 to drain, and finally, if the water level in the siphon cavity 237 is still too high and exceeds the rib 239, the water overflows into the drainage cavity 238 to drain. At this point, the bleed chamber 238 serves a dual bleed function to ensure that the water level in the siphon chamber 237 is normal.

The inner wall of the circumference of the detergent box 230 is inclined toward the inside of the detergent box 230. The water flowing into the drainage chamber 238 from the water diversion plate 220 can be collected into the receiving chamber of the box body 210 below along the inner wall of the inclined detergent box 230, and the inner wall of the inclined detergent box 230 can play a role of diversion, so that the overflowed water is collected towards the middle of the box body 210 and flows towards the water outlet 214 in the middle of the box body 210. In this embodiment, as shown in fig. 12, the water outlet 214 is elongated, and the water flowing out fills the water outlet 214 and flows out in a strip shape, so as to form a water flow having a width of the water outlet 214, such that the width of the water flow is large, the spraying range after being sprayed to the inner tub of the washing machine is large, contact between the clothes in the washing machine and the sprayed water flow is increased, the sprayed water flow forms a washing effect on the clothes, and removal of dirt on the clothes is facilitated. In other embodiments, the water outlet 214 may be one or more rows of water outlet holes.

As shown in fig. 11, at least one water blocking rib 216 is disposed on the box body 210 at the bottom of the accommodating chamber, and water siphoned out by the detergent box 230 is guided to the water outlet 214 through the water blocking rib 216. Through the water conservancy diversion effect of manger plate muscle 216, can make rivers flow to delivery port 214 more fast, and when siphon rivers were too big, can play and block the water conservancy diversion effect, prevent that rivers are partial to one side, influence the play water effect of delivery port 214, make the velocity of flow on the delivery port 214 bar width the same with the flow or close, guarantee that it is even to go out water.

When the water amount is too large and the water leaks from the drainage cavity 238, the water blocking rib 216 can guide the water flowing out from the drainage cavity 238, so as to prevent the water flowing out from the drainage cavity 238 from flowing over a large area, which causes the water flow to be deviated to one side.

The water blocking rib 216 is obliquely arranged on the bottom surface of the box body 210, one end of the water blocking rib 216 close to the water outlet 214 is arranged close to the central line of the water outlet 214, and the other end far away from the water outlet 214 is arranged far away from the central line of the water outlet 214. That is, from the water outlet 214, the water blocking ribs 216 are radially distributed, so that the water flow on the rear side and the water flow on the two sides can be guided and converged to the middle water outlet 214. In the embodiment, the drainage cavities 238 are disposed at both sides and the rear side of the detergent box 230, and the water blocking ribs 216 can well guide and collect drainage water flow at the rear side and both sides to the middle water outlet 214.

The water outlet 214 is disposed along the length of the cartridge body 210 and near the front side wall of the cartridge body 210. The water blocking ribs 216 are arranged on the rear side, and the water blocking ribs 216 can better play a role in guiding water flow on the two sides and the rear side.

In this embodiment, since the amount of water in the detergent siphon chamber 2371 is large, it is preferable that four water-blocking ribs 216 are provided, including a first water-blocking rib 2161, a second water-blocking rib 2162, a third water-blocking rib 2163, and a fourth water-blocking rib 2164. The water blocking rib 216 under the detergent siphon chamber 2371 and located at the outer side, i.e. the water blocking rib 216 close to the first drainage chamber is a first water blocking rib 2161, which is arc-shaped, and the front end of the first water blocking rib 2161, i.e. the end close to the water outlet 214, is bent outward, i.e. slightly bent toward the first drainage chamber. The water blocking rib 216 which is arranged below the softener siphon cavity 2372 and is positioned at the outer side, namely the water blocking rib 216 which is close to the third drainage cavity is a second water blocking rib 2162 and is also in an arc-shaped bent shape, and one end of the water blocking rib which is close to the water outlet 214 is bent towards the middle. That is, the first water blocking rib 2161 and the second water blocking rib 2162 are bent in opposite directions. The arrangement is that because the water flow is larger when the detergent siphon cavity 2371 overflows, the first water retaining rib 2161 is arranged into an arc shape for blocking the water flow, so that the water flow can be more effectively blocked from deviating to one side; the water quantity in the softener siphon cavity 2372 is small, large impact deflection water flow cannot be generated, and the second water retaining ribs 2162 are arranged in the shape of an arc which is bent reversely, so that the water flow can be guided to flow into the water outlet 214 better.

In this embodiment, the bottom of the cartridge 210 is provided with a step part 215, and the tray 120 is provided with a step matching part 121, and the cartridge 210 is received on the step matching part 121 of the tray through the step part 215.
