In the washing machine of the related art, water is diverted to multiple storage cavities of the detergent box through a pipe. This makes the arrangement of the water diverting channels inside the washing machine complicated, which brings about two drawbacks. First, the pipes are prone to breakdowns and are complicated to repair and maintain. Second, the production costs are high and the production efficiency is low, preventing widespread use.

The washing machine in the embodiment of the present disclosure integrates the diversion water channel into the diversion assembly, simplifying the water channel layout, reducing the probability of the washing machine's pipes failing, and reducing production costs.

As shown in FIG. 1, FIG. 1 is a schematic diagram of a washing machine loading system according to some embodiments of the present disclosure. The washing machine loading system includes a first loading device 1, a second loading device 2, a washing tub 3, a first water supply device 4, and a second water supply device 5.

The first dispenser 1 includes a storage box 11 having a box opening at the top, a first detergent box 12 provided in a box cavity of the storage box 11, and a water distribution assembly 13. The washing tub 3 is located below the storage box 11.

A drain port 111 and a detergent port 112 are provided at the bottom of the storage box 11, which are connected to the box cavity of the storage box 11. The drain port 111 is connected to the washing tub 3 via a connecting pipe a.

The first detergent box 12 includes three storage cavities 121. Each storage cavity 121 includes a storage cavity inlet 1211 and a storage cavity outlet 1212 that communicates with the box cavity of the storage box 11. The storage cavity inlets 1211 of each storage cavity 121 are located opposite the box mouth of the storage box 11. The storage cavities 121 are used to store detergent. By providing multiple storage cavities 121, various detergents with different functions, such as liquid detergent, laundry bleach, fabric softener, disinfectant, and powder detergent, can be placed in the first detergent box 12, thereby better meeting the laundry needs of users.

The water diversion assembly 13 is installed on the mouth of the storage box 11 and includes three water diversion cavities 131, each of which includes a water diversion cavity inlet 1311 and a water diversion cavity outlet 1312. The water diversion cavity outlets 1312 of each water diversion cavity 131 are located at the bottom of the water diversion cavity 131 and are respectively arranged opposite the storage cavity inlet 1211.

By integrating the water supply passages of the multiple storage cavities 121 inside the water distribution assembly 13, there is no need to connect multiple pipes to each of the three storage cavities 121, simplifying the installation of the pipes of the first input device 1 of the washing machine and making the structure of the first input device 1 more compact. The water distribution assembly 13 is installed on the mouth of the storage box 11, i.e., the water distribution assembly 13 is located above the first detergent box 12, so there is no need to pump the water in the water distribution cavity 131 to the storage cavity 121 with a pump, and the water in the water distribution cavity 131 can flow into the storage cavity 121 from the water distribution cavity outlet 1312 of the water distribution cavity 131 by the action of gravity, which in turn simplifies the configuration of the first input device 1.

Of course, the first detergent box 12 is not limited to having three storage cavities 121, but may have two, four, etc., depending on actual needs. The water distribution assembly 13 is not limited to having three water distribution cavities 131, but may have two, four, etc., depending on the number of storage cavities 121.

The second water supply device 5 includes a second water supply pipe 51. One end of the second water supply pipe 51 is connected to the water supply valve 52 of the washing machine, and the other end is connected to two water distribution cavities 131, respectively. The water supply valve 52 is connected to the water supply system of the washing machine.

Here, the water supply system may be a tap water system for providing primary use water.

The first water supply device 4 includes a water supply pump 41, a first water supply pipe 42, a pump water supply pipe 43, and a supply pipe 44. The water supply pump 41 is a vane pump, and the inlet of the water supply pump 41 is connected to a reusable water source via the supply pipe 44. The outlet of the water supply pump 41 is connected to one water distribution cavity inlet 1311 via the first water supply pipe 42. One end of the pump water supply pipe 43 is connected to one water distribution cavity 131 that is connected to the second water supply pipe 51, and the other end is connected to the pump cavity of the water supply pump 41.

The pump water supply pipe 43 can introduce some of the water from one water distribution cavity 131 that is connected to the second water supply pipe 51 into the pump cavity of the water supply pump 41, thereby assisting in starting the water supply pump 41 and making it easier to start the water supply pump 41.

Of course, the water pump 41 may be a pump of a type other than a vane pump. If the water pump 41 can be started by itself, the pump water pipe 43 does not need to be provided.

The above-mentioned reusable water source is used to provide reusable water, e.g., bath water, water used to wash fruits and vegetables, and other recyclable water. In this way, one water diversion cavity 131 of the water diversion assembly 13 can be dedicated to the inflow of reusable water. The reusable water can also be used to wash suitable clothes, thereby conserving water resources and meeting the laundry needs of the user.

Of course, the first water supply pipe 42 may be connected to the water diversion cavity inlets 1311 of two water diversion cavities 131, and the second water supply pipe 51 may be connected to the water diversion cavity inlet 1311 of one water diversion cavity 131, as long as it is ensured that each water diversion cavity 131 is connected to either the first water supply pipe 42 or the second water supply pipe 51.

The second dispenser 2 includes two second detergent boxes 21, a dispenser pump 22, two first pipelines 23, a second pipeline 24, and a third pipeline 25. An inlet 211 is provided at the top end of each second detergent box 21.

The dosing pump 22 includes a pump cavity 221, an inlet end 222 communicating with the pump cavity 221, an outlet end 223, and a communication port 224. The first end of each first conduit 23 communicates with the corresponding second detergent box 21, and the second end communicates with the inlet end 222 of the dosing pump 22.

One end of the second pipeline 24 is connected to the outlet end 223 of the dosing pump 22, and the other end is connected to the detergent port 112 of the storage box 11.

One end of the third conduit 25 is connected to one of the water diversion cavities 131, and the other end is connected to the communication port 224 of the input pump 22. This allows the third conduit 25 to introduce water from one of the water diversion cavities 131 into the pump cavity 221 of the input pump 22, thereby washing away detergent remaining in the pump cavity 221 of the input pump 22 and in the second conduit 24.

The number of second detergent boxes 21 may be two, one, three, etc., and is not specifically limited here.

A selection button is provided on the operation panel of the washing machine. The selection button allows the user to choose whether to load laundry using the first loading device 1 or the second loading device 2.

When using the first dispenser 1 to dispense detergent, the user dispenses a preset amount of detergent into the storage cavity 121 of the first detergent box 12. Water then flows into the water diversion cavity 131 from the water diversion cavity inlet 1311, and flows into the storage cavity 121 of the first detergent box 12 from the water diversion cavity outlet 1312 by the action of gravity, and mixes with the detergent in the storage cavity 121 to form a detergent solution. The detergent solution flows into the storage box 11 from the storage cavity outlet 1212 of the storage cavity 121, and flows into the washing tub 3 from the drain port 111 by the action of gravity, thereby completing the dispensing of the detergent.

When the second dispenser 2 is used for dispensing, the detergent in the second detergent box 21 flows into the storage box 11 through the first pipe 23, the second pipe 24, and the detergent port 112 by the suction action of the dispenser pump 22, and is mixed with water in the storage box 11 (water from the water supply system or reusable water source flows into the box cavity of the storage box 11 through the water distribution assembly 13 and the storage cavity 121, and no detergent is placed in the storage cavity 121 at this time) to form a detergent solution. The detergent solution then flows into the washing tub 3 through the drain port 111 and the connecting pipe a, thereby completing the detergent dispensing. The second dispenser 2 controls the amount of detergent dispensed by the dispenser pump 22, eliminating the need for the user to manually control the amount of detergent dispensed, thereby reducing the burden on the user and improving the user's usage experience.

The storage box 11 corresponds to a mixing container provided between the first detergent box 12, the second detergent box 21, and the washing tub 3. After the detergent in the storage cavity 121 of the first detergent box 12 is brought into the storage box 11 by water, the detergent can be sufficiently mixed with the water in the storage box 11 and dissolved. The sufficiently dissolved detergent can smoothly flow through the connecting pipe and into the washing tub 3, greatly reducing the risk of the undissolved detergent remaining in the connecting pipe and clogging the pipe. In addition, when the detergent in the second detergent box 21 is sucked into the storage box 11 by the input pump 22, it can be sufficiently mixed with the water and dissolved to form a detergent solution, which reduces the flow viscosity of the detergent and thus prevents the detergent from remaining in the pipe and clogging the pipe.

In addition to providing both the first and second loading devices 1 and 2 in the above-mentioned washing machine loading system, it is also possible to provide only one of the first and second loading devices 1 and 2 depending on the actual situation.

As shown in FIG. 1, in order to facilitate the following explanation, the three water diversion cavities 131 are named as follows. The three water diversion cavities 131 are respectively called the first water diversion cavity 131a, the second water diversion cavity 131b, and the third water diversion cavity 131c.

The diversion cavity inlet 1311 and the diversion cavity outlet 1312 of the first diversion cavity 131a are called the first diversion cavity inlet 1311a and the first diversion cavity outlet 1312a, respectively.

The diversion cavity inlet 1311 and the diversion cavity outlet 1312 of the second diversion cavity 131b are referred to as the second diversion cavity inlet 1311b and the second diversion cavity outlet 1312b, respectively.

The diversion cavity inlet 1311 and the diversion cavity outlet 1312 of the third diversion cavity 131c are referred to as the third diversion cavity inlet 1311c and the third diversion cavity outlet 1312c, respectively.

The first water diversion cavity inlet 1311a and the second water diversion cavity inlet 1311b are both connected to the second water supply pipe 51, and the third water diversion cavity inlet 1311c is connected to the first water supply pipe 42.

The washing machine may be a pulsator washing machine, a drum washing machine, or a multi-tub washing machine having a pulsator-type washing tub and a drum-type washing tub; there are no specific limitations here.

Below, the specific configuration of the washing machine loading system in the embodiment of this disclosure will be explained using a pulsator washing machine as an example.

As shown in FIG. 2 and FIG. 3, FIG. 2 is a structural schematic diagram of a washing machine in some embodiments of the present disclosure. FIG. 3 is an exploded view of the first input device 1, the second input device 2, and the surrounding frame of the washing machine in FIG. 2. This washing machine includes a housing 6. The housing 6 includes a housing body 61 and a surrounding frame 62 provided on the top of the housing body 61. The washing tub 3 is provided in the housing body 61. The surrounding frame 62 includes a clothes input port 621 provided opposite the tub mouth of the washing tub 3, and a storage cavity 622 located on the rear side of the clothes input port 621 and communicating with the clothes input port 621. The first input device 1 and the second input device 2 are arranged side by side in the horizontal direction and are removably attached in the storage cavity 622.

As shown in Figs. 4, 5, and 6, Fig. 4 is a structural schematic diagram of the first dispenser 1 and the second dispenser 2. Fig. 5 is an exploded view of the first dispenser 1 in Fig. 4. Fig. 6 is a view showing the state after the first detergent box 12 has been pulled out from the storage box 11. The first detergent box 12 is formed in a substantially rectangular parallelepiped shape and has an opening on the front side of the storage box 11. The first detergent box 12 is slidably connected to the storage box 11 so that it can be slidably pulled out horizontally from the front opening of the storage box 11. This makes it easy for the user to add detergent to the storage cavity 121 of the first detergent box 12, ensuring that the detergent is smoothly dispensed into the washing tub 3 by the first dispenser 1.

In some embodiments, as shown in FIG. 7 and FIG. 8, FIG. 7 is a diagram showing the state in which the first detergent box 12 is arranged in the storage box 11. FIG. 8 is a diagram showing the arrangement of the storage cavity 121 in the first detergent box 12. The first detergent box 12 includes a box bottom wall 122, a box side wall 123 located on the periphery of the box bottom wall 122, and a separation wall 124 provided on the box side wall 122. The box cavity of the first detergent box 12 is formed by being surrounded by the box bottom wall 122 and the box side wall 123. The separation wall 124 divides the box cavity of the first detergent box 12 into a plurality of storage cavities 121. Compared to providing each storage cavity 121 as an independent sub-box body, by dividing the box cavity of the first detergent box 12 into a plurality of storage cavities 121 by the separation wall 124, two storage cavities 121 can share one separation wall 124. This allows for savings in manufacturing materials for the first detergent box 12 and simplifies the internal structure of the first detergent box 12.

In some embodiments, as shown in Figures 7 and 8, the multiple storage cavities 121 are each a first storage cavity 121a and two second storage cavities 121b spaced apart along a first horizontal direction X. In the second horizontal direction Y, the two second storage cavities 121b are located on the same side of the first storage cavity 121a, and the second horizontal direction Y is perpendicular to the first horizontal direction X.

A drain groove 125 is formed between the two second storage cavities 121b. One end of the drain groove 125 communicates with the first storage cavity 121a, and the other end communicates with the box cavity of the storage box 11. The drain groove 125 is the storage cavity outlet 1212 of the first storage cavity 121a.

The first storage cavity 121a can hold solid detergent such as powder detergent, and the two second storage cavities 121b can hold liquid detergent such as liquid detergent and fabric softener. The first storage cavity 121a communicates with the storage box 11 via the drain groove 125. This makes it easy for the detergent in the first storage cavity 121a to flow into the storage box 11 after mixing with water.

In some embodiments, as shown in FIG. 9, FIG. 9 is a cross-sectional view of the A-A section in FIG. 7. The first input device 1 further includes a siphon member 14. The siphon member 14 includes a riser pipe 141 and a siphon cap 142. The riser pipe 141 is installed in the second storage cavity 121b. The lower end of the riser pipe 141 communicates with the storage cavity outlet 1212 located at the bottom of the second storage cavity 121b. The siphon cap 142 is fitted onto the riser pipe 141. The siphon cap 142 has gaps between the bottom wall of the second storage cavity 121b, the upper end of the riser pipe 141, and the side wall of the riser pipe 141, through which liquid can pass.

When the first dosing device 1 is operated, the detergent in the second storage cavity 121b is mixed with water to form a detergent solution. Due to the siphoning action of the siphon member 14, the detergent solution rises along the gap between the siphon cap 142 and the side wall of the riser pipe 141, flows into the riser pipe 141 from the upper end of the riser pipe 141, and then flows into the storage box 11 along the lower end of the riser pipe 141.

Of course, the siphon member 14 may be provided as a siphon tube other than the above structure, and the specific structure can be determined according to the actual situation.

In some embodiments, as shown in FIG. 10, FIG. 10 is a schematic diagram of the structure of the storage box 11. The bottom of the storage box 11 is inclined along the second horizontal direction Y, and the drainage port 111 is provided at one end where the bottom of the storage box 11 is located at a lower position.

As shown in Figures 7 and 10, by slanting the bottom of the storage box 11, the detergent solution that flows out from the storage cavity 121 in the first detergent box 12 can collect at a low point on the bottom of the storage box 11 by the action of gravity, so that it can flow into the washing tub 3 more quickly from the drainage port 111 at the bottom of the storage box 11, and residual detergent solution does not accumulate in the storage box 11.

The inclination angle of the bottom of the storage box 11 may be 1° to 10°, 1° to 15°, or 1° to 20°. The specific inclination angle can be set according to actual needs and is not particularly limited here.

In some embodiments, as shown in Figures 1, 4 and 5, the diversion assembly 13 includes a diversion plate 132 and a cover plate 133. The diversion plate 132 is provided with three diversion grooves 134, a first diversion groove 134a, a second diversion groove 134b and a third diversion groove 134c. The cover plate 133 is removably attached to the diversion plate 132 such that the cover plate 133 and the first diversion groove 134a form a first diversion cavity 131a, the cover plate 133 and the second diversion groove 134b form a second diversion cavity 131b, and the cover plate 133 and the third diversion groove 134c form a third diversion cavity 131c. Compared to connecting the water diversion plate 132 and the cover plate 133 by welding, the water diversion plate 132 and the cover plate 133 are removably connected, so that if the first water diversion cavity 131a, the second water diversion cavity 131b, or the third water diversion cavity 131c becomes clogged, the cover plate 133 can be easily removed from the water diversion plate 132 and the clogged area can be cleaned.

Here, the distance between the water distribution plate 132 and the cover plate 133 can be set to 6 mm or more so that water can flow smoothly between them.

Of course, the water distribution plate 132 may have two water distribution grooves 134 or four water distribution grooves 134, and this is not specifically limited here. As can be understood by those skilled in the art, the number of water distribution cavities 131 is the same as the number of water distribution grooves 134 provided in the water distribution plate 132.

In some embodiments, as shown in Figures 5 and 6, the water distribution assembly 13 includes a plurality of separation ribs 135 installed on one side surface of the water distribution plate 132, and the plurality of separation ribs 135 form a first water distribution groove 134a, a second water distribution groove 134b, and a third water distribution groove 134c with the water distribution plate 132. By providing the separation ribs 135 to the water distribution groove 134 to form the plurality of water distribution grooves 134, it is not necessary to open the water distribution groove 134 by removing material from the water distribution plate 132, and the thickness of the water distribution plate 132 can be reduced, which is advantageous in reducing the weight of the water distribution plate 132.

In some embodiments, as shown in Figures 5 and 6, the bottom of the first water diversion groove 134a, the second water diversion groove 134b, and the third water diversion groove 134c each have one protrusion 136 (or multiple protrusions 136). Each protrusion 136 has a through hole 1361, one end of which is connected to the underside of the water diversion plate 132, and the other end is connected to the upper side of the water diversion plate 132. In this way, the through hole 1361 can equalize the air pressure on both the upper and lower sides of the water diversion plate 132, so that the water can smoothly flow from the water diversion groove 134 on the water diversion plate 132 into the storage cavity 121.

Each protrusion 136 may have one through hole 1361 or may have multiple through holes 1361. The multiple through holes 1361 may be provided at different heights of the protrusion 136 so that the air pressure on both the upper and lower sides of the water dividing plate 132 quickly becomes equal.

When one through hole 1361 is provided in the protrusion 136, as shown in Figures 5 and 6, this through hole 1361 is provided at one end of the protrusion 136 away from the water diversion plate 132. This makes it difficult for the through hole 1361 to become submerged even if there is a high level of water in the water diversion groove 134, and allows air to pass through.

As shown in Figures 5 and 6, the height of the protrusion 136 is equal to or greater than the height of the separation rib 135, which raises the position of the upper end opening of the through hole 1361 and makes the through hole 1361 less likely to become submerged.

In some embodiments, as shown in FIG. 11 and FIG. 13, FIG. 11 is a plan view of the first input device 1 and the second input device 2, and FIG. 13 is a view showing the state after the cover plate 133 is removed from the first input device 1 and the second input device 2 in FIG. 11. The first water diversion cavity inlet 1311a is provided at a position opposite the first water diversion groove 134a of the cover plate 133. The second water diversion cavity inlet 1311b is provided at a position opposite the second water diversion groove 134b of the cover plate 133. The third water diversion cavity inlet 1311c is provided at a position opposite the third water diversion groove 134c of the cover plate 133. The first water supply pipe 42 communicates with the third water diversion cavity inlet 1311c. The second water supply pipe 51 communicates with the first water diversion cavity inlet 1311a and the second water diversion cavity inlet 1311b, respectively.

As a result, as shown in FIG. 13, the primary water transported by the second water supply pipe 51 flows from the first water diversion cavity inlet 1311a and the second water diversion cavity inlet 1311b into the first water diversion groove 134a and the second water diversion groove 134b, respectively, and is diverted. The reusable water transported by the first water supply pipe 42 can flow from the third water diversion cavity inlet 1311c into the third water diversion groove 134c.

As shown in Figures 11 and 12, Figure 12 is a cross-sectional view of the B-B cross section in Figure 11. The second water supply pipe 51 is connected to the first water diversion cavity inlet 1311a via the first guide member 53. The first guide member 53 has a flow guide plate 531. The flow guide plate 531 is provided at an incline with respect to the horizontal plane and is provided opposite the first water diversion cavity inlet 1311a. By providing the flow guide plate 531 at an incline within the first guide member 53, the flow guide plate 531 can gently change the direction of the water flow, thereby allowing the water in the second water supply pipe 51 to smoothly flow from the first water diversion cavity inlet 1311a into the first water diversion groove 134a.

As shown in Figures 11 and 12, the second water supply pipe 51 is further connected to the second water diversion cavity inlet 1311b via a second guide member 54. The structure of the second guide member 54 is made similar to the structure of the first guide member 53 so that the water in the second water supply pipe 51 smoothly flows from the second water diversion cavity inlet 1311b into the second water diversion groove 134b.

In some embodiments, as shown in FIG. 13, the first water diversion groove 134a is arranged opposite the storage cavity inlet 1211 of one of the second storage cavities 121b (the circle on the left side of the figure represents the area facing the storage cavity inlet 1211 of one of the second storage cavities 121b on the water diversion plate 132), and a plurality of first water diversion cavity outlets 1312a are provided in the area of the first water diversion groove 134a facing the storage cavity inlet 1211 of the second storage cavity 121b. As a result, when the water flows through the area of the first water diversion groove 134a facing the second storage cavity 121b, it flows into the second storage cavity 121b through the plurality of first water diversion cavity outlets 1312a, and can thereby be mixed with the detergent in the second storage cavity 121b.

The second water diversion groove 134b is provided opposite the storage cavity inlet 1211 of the first storage cavity 121a and the other second storage cavity 121b (the circle on the right side of the figure represents the area facing the storage cavity inlet 1211 of the other second storage cavity 121b on the water diversion plate 132, and the rectangle on the lower side of the figure represents the area facing the storage cavity inlet 1211 of the first storage cavity 121a on the water diversion plate 132), and a plurality of second water diversion cavity outlets 1312b are provided in the area of the second water diversion groove 134b facing the storage cavity inlet 1211 of the first storage cavity 121a and in the area facing the storage cavity inlet 1211 of the other second storage cavity 121b. As a result, when the water flows through the area of the second water diversion groove 134b facing the first storage cavity 121a and the other second storage cavity 121b, it flows through the multiple second water diversion cavity outlets 1312b into the first storage cavity 121a and the other second storage cavity 121b, thereby mixing with the detergent in the first storage cavity 121a and the other second storage cavity 121b, respectively.

The third water diversion groove 134c is provided opposite the storage cavity inlet 1211 of the first storage cavity 121a and the other second storage cavity 121b, and a plurality of third water diversion cavity outlets 1312c are provided in the area where the second water diversion groove 134b and the storage cavity inlet 1211 of the first storage cavity 121a face each other. As a result, when the water flows through the area of the third water diversion groove 134c facing the first storage cavity 121a, it flows into the first storage cavity 121a through the plurality of third water diversion cavity outlets 1312c, and can thereby be mixed with the detergent in the first storage cavity 121a.

Of course, as shown in Figures 6 and 13, the first water diversion groove 134a may be provided opposite the storage cavity inlet 1211 of a single storage cavity 121, or opposite the storage cavity inlet 1211 of multiple storage cavities 121, and multiple first water diversion cavity outlets 1312a are provided in at least one of the areas of the first water diversion groove 134a facing each storage cavity inlet 1211.

The second water diversion groove 134b and the third water diversion groove 134c may face the storage cavity inlet 1211 of one storage cavity 121 in addition to facing the storage cavity inlet 1211 of two storage cavities 121. In the third water diversion groove 134c, a plurality of third water diversion cavity outlets 1312c may be provided in the area facing the storage cavity inlet 1211 of the second storage cavity 121b.

The shapes of the first water diversion cavity inlet 1311a, the second water diversion cavity inlet 1311b, and the third water diversion cavity inlet 1311c may be circular, rectangular, diamond-shaped, etc., and are not specifically limited here.

In some embodiments, as shown in FIG. 13, the second water diversion groove 134b includes a sub-groove section 1341 arranged in a serpentine manner. The bottom of the sub-groove section 1341 is arranged opposite the storage cavity inlet 1211 of the first storage cavity 121a, and a plurality of second water diversion cavity outlets 1312b are opened at the bottom of the sub-groove section 1341 along the extension direction of the sub-groove section 1341. In this way, when the water flows through the sub-groove section 1341, it can flow into the first storage cavity 121a in large quantities, and it can be ensured that every position in the first storage cavity 121a is washed with water and the detergent is thoroughly mixed with the water, thereby preventing the detergent from remaining in the first storage cavity 121a.

In addition to the second water diversion groove 134b, the first water diversion groove 134a and the third water diversion groove 134c may also be provided with a sub-groove section 1341 that is installed in a serpentine manner, and the specific shape of the storage cavity inlet 1211 facing the water diversion groove 134 may be determined.

In some embodiments, as shown in FIG. 13, in the third diversion groove 134c, a plurality of third diversion cavity outlets 1312c are spaced apart along the extension direction of the third diversion groove 134c. This ensures that the water in the third diversion groove 134c flows uniformly into the first storage cavity 121a so as to be thoroughly mixed with the detergent in the first storage cavity 121a.

Of course, in the first water diversion groove 134a, multiple first water diversion cavity outlets 1312a may be spaced apart along the extension direction of the first water diversion groove 134a, and specifically, this can be determined according to the shape of the storage cavity inlet 1211 facing this water diversion groove 134.

In some embodiments, as shown in FIG. 6 and FIG. 13, in the sub-channel section 1341 of the second water diversion channel 134b, the size of the plurality of second water diversion cavity outlets 1312b gradually increases along the direction of water flow in the sub-channel section 1341. Since the water flow rate is slowed along the extension direction of the sub-channel section 1341, the size of the plurality of second water diversion cavity outlets 1312b gradually increases along the direction of water flow, so that the amount of water flowing out of the second water diversion cavity outlets 1312b at different positions in a certain time can be made consistent, thereby making the amount of water at different positions in the first storage cavity 121a consistent and making the detergent in the first storage cavity 121a better mixed and dissolved with the water.

In some embodiments, as shown in FIG. 13, in the third diversion channel 134c, the size of the plurality of third diversion cavity outlets 1312c gradually increases along the direction in which the water flows through the third diversion channel 134c. This allows the amount of water flowing out of the third diversion cavity outlets 1312c at different positions in a certain period of time to be consistent, thereby allowing the amount of water at different positions in the first storage cavity 121a to be consistent and allows the detergent in the first storage cavity 121a to be better mixed and dissolved with the water.

As is clear from the size distribution pattern of the multiple second water diversion cavity outlets 1312b and the multiple third water diversion cavity outlets 1312c in FIG. 13, by installing the multiple water diversion cavity outlets 1312 in the water diversion groove 134 so that their sizes gradually increase along the direction of the water flow, it is possible to ensure that the amount of water flowing out of each water diversion cavity outlet 1312 is approximately equal.

In some embodiments, as shown in Figures 14, 15 and 16, Figure 14 is a structural schematic diagram of the underside of the water distribution plate 132. Figure 15 is a structural schematic diagram after the water distribution assembly 13 is removed from the first input device 1. Figure 16 is a cross-sectional view of the C-C section in Figure 13. The water distribution assembly 13 includes a plurality of shower pipes 137 located below the water distribution plate 132. For each shower pipe 137, the upper end pipe mouth of the shower pipe 137 is connected to one water distribution cavity outlet 1312, and the lower end pipe mouths are all installed toward the storage cavity inlet 1211. During operation, the water in the water distribution groove 134 flows into the shower pipe 137 from the water distribution cavity outlet 1312, and then flows into the storage cavity 121 from the lower end pipe mouth of the shower pipe 137. The lower end pipe port of the shower pipe 137 is closer to the storage cavity 121, which reduces water splashing when water flows from the lower end pipe port of the shower pipe 137 into the storage cavity 121.

As shown in FIG. 16, the inner diameter of the shower pipe 137 matches the area of the connected water distribution cavity outlet 1312, where "match" means equal to or close to.

In some embodiments, as shown in Figs. 16 and 17, Fig. 17 is an enlarged view of the shower pipe 137 in Fig. 16. The shower pipe 137 extends vertically. The inner wall of the shower pipe 137 includes a cylindrical pipe inner wall 1371 and a flow guide wall 1372 connected between the pipe inner wall 1371 and the lower end surface of the shower pipe 137. The flow guide wall 1372 is positioned to change the direction of the water flow ejected from the shower pipe 137 so that the direction of the water flow forms an obtuse angle with the pipe inner wall 1371.

By providing the flow guide wall 1372, the water flow forms an obtuse angle with the inner wall 1371 of the shower pipe 137 when it is ejected from the shower pipe 137. In this way, the water flow ejected from the shower pipe 137 can clean areas around the shower pipe 137, such as the siphon member 14. This allows the shower pipe 137 to send water into the storage cavity 121, and can also be used as a cleaning head to clean other areas.

The number of shower pipes 137 having flow guide walls 1372 may be one or more, and can be determined according to the actual situation.

The shape of the guide wall 1372 is not limited, and in some embodiments, as shown in FIG. 17, the guide wall 1372 may be curved. In other embodiments, the guide wall 1372 may be inclined. Compared to being inclined, when the guide wall 1372 is curved, it has a curved surface and no corners, which allows the direction of the water flow to be changed gently and allows the water flow to be guided better.

In some embodiments, in order to change the direction of the water flow more gently, as shown in FIG. 17, the pipe inner wall 1371 is tapered, and the small end of the pipe inner wall 1371 is connected to the flow guide wall 1372. By arranging the pipe inner wall 1371 in a tapered cylindrical shape, i.e., by slanting the pipe inner wall 1371, the transition at the connection point between the pipe inner wall 1371 and the flow guide wall 1372 can be made more gradual, thereby changing the direction of the water flow more gently and better guiding the water flow.

In some embodiments, as shown in FIG. 17, the lower end surface of the shower pipe 137 is inclined with respect to the horizontal plane so that the water flow can be easily ejected from the shower pipe 137. In a vertical cross section (i.e., cross section C-C in FIG. 13) passing through the central axis of the shower pipe 137, the position of the first end (i.e., the left end) of the lower end surface of the shower pipe 137 is lower than the position of the second end (i.e., the right end) of the lower end surface. The flow guide wall 1372 is located at the first end close to the lower end surface of the shower pipe 137.

As shown in FIG. 17, the distance between the second end of the lower end surface of the shower pipe 137 and the water distribution plate 132 is greater than 4 mm.

As shown in FIG. 17, when the water flow in the shower pipe 137 is directed by the flow guide wall 1372 and ejected downward to the right, the right end of the lower end face of the shower pipe 137 is set higher, which prevents interference between the wall of the shower pipe 137 and the ejected water flow, allowing the water flow to be ejected more smoothly from the shower pipe 137.

In some embodiments, the shower pipe 137 is installed as shown in FIG. 16 and FIG. 18 so that the water flow emitted from the shower pipe 137 can better clean the components around the shower pipe 137. FIG. 18 is a structural schematic diagram of the shower pipe 137 according to some embodiments of the present disclosure. The shower pipe 137 includes an upper pipe section 1373 and a lower pipe section 1374 located below the upper pipe section 1373.

The upper end of the upper pipe section 1373 is connected to the water diversion cavity outlet 1312. The flow guide wall 1372 is located at the lower end pipe mouth of the lower pipe section 1374. The lower end of the upper pipe section 1373 extends into the lower pipe section 1374 and is connected to the lower pipe section 1374 by a rotating structure 138, which allows the lower pipe section 1374 to rotate relative to the upper pipe section 1373.

By rotating the lower pipe section 1374 relative to the upper pipe section 1373, the orientation of the lower end pipe port of the lower pipe section 1374 can be adjusted, which makes it easier to clean multiple members around the shower pipe 137. For example, if the shower pipe 137 located on the left side of FIG. 16 is replaced with the shower pipe 137 shown in FIG. 18, rotating the lower pipe section 1374 can clean both the siphon member 14 and the box side wall 123 of the first detergent box 12.

In some embodiments, the rotation structure 138 includes an annular engagement groove 1381 provided in the lower tube section 1374 and an annular convex rib 1382 provided in the upper tube section 1373, as shown in FIG. 18. The annular convex rib 1382 engages with the annular engagement groove 1381 to enable rotation of the lower tube section 1374 relative to the upper tube section 1373. This connection structure is relatively simple and does not require the addition of other parts, which is advantageous in reducing costs.

Of course, the installation positions of the annular engagement groove 1381 and the annular convex rib 1382 may be interchanged, i.e., the annular engagement groove 1381 is provided in the upper pipe section 1373, and the annular convex rib 1382 is provided in the lower pipe section 1374. This also makes it possible to rotate the lower pipe section 1374 relative to the upper pipe section 1373.

In the shower pipe 137 shown in FIG. 18, the lower end of the upper pipe section 1373 enters the lower pipe section 1374. Of course, in addition to this installation method, the upper end of the lower pipe section 1374 may be inserted into the upper pipe section 1373, and the lower pipe section 1374 may be connected to the upper pipe section 1373 via the rotating structure 138. This also makes it possible to rotate the lower pipe section 1374 relative to the upper pipe section 1373.

In some embodiments, in order to facilitate separation between the upper pipe section 1373 and the lower pipe section 1374, as shown in FIG. 19, a guide surface 1383 is formed on one side edge of the annular engagement groove 1381. When the cross-sectional shape of the annular convex rib 1382 is hemispherical and it is necessary to separate the upper pipe section 1373 and the lower pipe section 1374, if the lower pipe section 1374 is pulled downward strongly, the annular convex rib 1382 moves along the guide surface 1383 and presses one groove wall of the annular engagement groove 1381, causing the annular convex rib 1382 to be released from the annular engagement groove 1381, thereby separating the upper pipe section 1373 from the lower pipe section 1374. This makes it easier to repair, maintain, or replace the lower pipe section 1374.

In some embodiments, as shown in Figures 20 and 21, Figure 20 shows a cross-sectional view of section D-D in Figure 11. Figure 21 is an enlarged view of the seal structure 15 in Figure 20. To prevent liquid from spilling out of the containment box 11, the edge of the water distribution plate 132 is connected to the containment box 11 via the seal structure 15. This avoids safety concerns caused by liquid spilling out of the containment box 11 coming into contact with wiring inside the washing machine.

In some embodiments, as shown in Figures 14, 15, and 21, the seal structure 15 includes a first stop rib 151 provided on the periphery of the water distribution plate 132 and an insertion groove 152 provided on the periphery of the mouth of the storage box 11. The first stop rib 151 extends along the periphery of the water distribution plate 132, and the insertion groove 152 extends along the periphery of the mouth of the storage box 11. The first stop rib 151 is inserted by fitting into the insertion groove 152. This seal structure 15 is simple and does not require the addition of other parts, which is advantageous in reducing costs.

Of course, the positions of the first stop rib 151 and the insertion groove 152 may be interchanged, i.e., the first stop rib 151 may be provided on the periphery of the mouth of the storage box 11, and the insertion groove 152 may be provided on the periphery of the water distribution plate 132. This can also prevent liquid from overflowing from the storage box 11.

In some embodiments, in order to enhance the sealing effect between the water distribution plate 132 and the storage box 11, as shown in FIG. 20 and FIG. 21, the sealing structure 15 further includes a second stop rib 153 provided on the periphery of the water distribution plate 132. The second stop rib 153 is located inside the first stop rib 151 and is provided at a distance from the first stop rib 151. One side groove wall along the width direction of the insertion groove 152 is inserted between the first stop rib 151 and the second rib 153 by fitting, that is, the groove formed by the first stop rib 151 and the second stop rib 153 is inserted into the insertion groove 152. By installing in this manner, the length of the path through which the liquid overflows outside the storage box 11 is increased, and the probability that the liquid in the storage box 11 overflows outside the storage box 11 is greatly reduced, thereby improving the sealing effect between the water distribution plate 132 and the storage box 11.

In some embodiments, as shown in FIG. 15 and FIG. 22, FIG. 22 is an enlarged view of the upper left corner of the storage box 11 in FIG. 15. The insertion groove 152 is provided in the side wall of the storage box 11. The side wall of the storage box 11 is further provided with a discharge groove 114 extending vertically. The upper end of the discharge groove 114 communicates with the insertion groove 152, and the lower end of the discharge groove 114 extends to the bottom wall of the storage box 11.

By providing the drain groove 114, when liquid such as water flows into the insertion groove 152, the liquid in the insertion groove 152 can flow through the drain groove 114 into the storage box 11 and then through the drain outlet 111 of the storage box 11 into the washing tub 3. This prevents liquid from accumulating in the insertion groove 152.

In some embodiments, in order to prevent the detergent in one second storage cavity 121b from splashing into another storage cavity 121 and causing mixed contamination, as shown in Figures 14, 15 and 16, the water divider plate 132 is further provided with a third stop rib 154. The third stop rib 154 extends along the second horizontal direction Y and is inserted into the drain groove 125. In this way, the third stop rib 154 separates the two second storage cavities 121b, and can prevent the detergent in the two second storage cavities 121b from splashing into each other and causing mixed contamination of different types of detergent.

Here, as shown in Figures 14 and 16, the number of third stop ribs 154 is two. The two third stop ribs 154 abut against the groove walls on both sides of the drainage groove 125, respectively. This allows the connection between the third stop ribs 154 and the drainage groove 125 to be made tighter.

In some embodiments, in order to firmly attach the water distribution plate 132 to the opening of the storage box 11, as shown in Figures 14, 15 and 16, a mounting notch 1231 is formed at the top of the box side wall 123, and a positioning portion 155 is further provided on the water distribution plate 132. The positioning portion 155 fits into the mounting notch 1231. The water distribution plate 132 can be positioned by fitting the positioning portion 155 into the mounting notch 1231. This makes it easier to align the first stop rib 151 and the insertion groove 152, and also makes the attachment between the water distribution plate 132 and the storage box 11 stronger.

As shown in FIG. 15, the mounting notch 1231 can be provided in one box side wall 123 along the second horizontal direction Y of the first detergent box 12. This allows the water distribution plate 132 to be positioned in the first horizontal direction X.

The structure of the positioning portion 155 is not unique, and in some embodiments, as shown in FIG. 16, the positioning portion 155 includes a first positioning rib 1551 and a second positioning rib 1552 that are arranged in parallel and spaced apart. The first positioning rib 1551 abuts one end of the mounting notch 1231. The second positioning rib 1552 abuts the other end of the mounting notch 1231.

In another embodiment, the positioning portion is a positioning block that fits into the mounting notch 1231 and both ends of the positioning block abut against the mounting notch 1231. Compared to providing the positioning portion as a positioning block, providing the positioning portion as a first positioning rib 1551 and a second positioning rib 1552 that are spaced apart can reduce the space occupied by the positioning portion and can also reduce the weight of the positioning portion, thereby reducing the weight of the water distribution plate 132.

In some embodiments, to further strengthen the connection between the water distribution plate 132 and the storage box 11, as shown in Figures 10, 14, and 15, a plurality of snap fasteners 1321 are provided on the edge of the water distribution plate 132, and a plurality of engagement holes 127 are provided on the edge of the box opening of the storage box 11. The plurality of snap fasteners 1321 engage one-to-one with the plurality of engagement holes 127, so that the water distribution plate 132 is more firmly attached to the box opening of the storage box 11.

In some embodiments, as shown in Figures 23, 24, and 25, Figure 23 is an exploded view of the second input device 2. Figure 24 is a rear view of the first input device 1 and the second input device 2. Figure 25 is a cross-sectional view of the E-E section in Figure 5. The second input device 2 includes a storage case 26 provided in the housing 6, a second detergent box 21 having an input port 211 at the top end, an input pump 22, a first pipeline 23, and a second pipeline 24.

As shown in FIG. 23, the storage case 26 has a substantially rectangular parallelepiped case structure and has an opening at the tip of the storage case 26. The second detergent box 21 has a rectangular parallelepiped box structure. The second detergent box 21 is provided inside the storage case 26 and can be slid out from the opening at the tip of the storage case 26 to the outside of the storage case 26, so that the input port 211 can be positioned outside the storage case 26.

The second detergent box 21 may be connected to the storage case 26 by a slide rail so that the second detergent box 21 can be slid out of the storage case 26. The second detergent box 21 may also be connected to the storage case 26 by a push lock. The push lock can lock the second detergent box 21 when the second detergent box 21 is positioned inside the storage case 26, preventing the second detergent box 21 from sliding out of the storage case 26 due to the action of an external force.

As shown in Figures 24 and 25, the injection pump 22 is a plunger pump including a pump cavity 221 and an inlet end 222 and an outlet end 223 that communicate with the pump cavity 221. The inlet end 222 of the injection pump 22 enters the housing case 26.

The first end of the first pipe 23 is connected to the second detergent box 21, and the second end of the first pipe 23 is arranged to be connected to the inlet end 222 of the input pump 22. As shown in FIG. 23, when the second detergent box 21 is pulled out of the storage case 26, the second end of the first pipe 23 can be separated from the inlet end 222 of the input pump 22.

As shown in FIG. 24, one end of the second pipeline 24 is connected to the outlet end 223 of the input pump 22, and the other end is connected to the box cavity of the storage box 11.

As shown in FIG. 25, a mounting hole 212 is provided in the box wall of the second detergent box 21 near the input pump 22. The first pipeline 23 is provided in the box cavity of the second detergent box 21. The second end of the first pipeline 23 is connected to the mounting hole 212. By providing the first pipeline 23 in the box cavity of the second detergent box 21, the second end of the first pipeline 23 does not need to extend outside the second detergent box 21. This significantly reduces the probability that the second end of the first pipeline 23 will be damaged due to movement interference with other components when the second detergent box 21 is pulled out of the storage case 26 or pushed back into the storage case 26.

As shown in FIG. 25 to FIG. 28, FIG. 26 is a side view of the state in which the second detergent box 21 is located in the storage case 26. FIG. 27 is a plan view of the state after the second detergent box 21 is pulled out from the storage case 26. FIG. 28 is a cross-sectional view of the F-F section in FIG. 27. When the detergent in the second detergent box 21 is about to be used up, the user pulls out the second detergent box 21 from the storage case 26 and adds detergent from the input port 211 to ensure that the detergent in the second detergent box 21 is continuously supplied. At this time, as shown in FIG. 28, the second end of the first pipe 23 is separated from the inlet end 222 of the input pump 22. When the addition of the detergent is completed, the second detergent box 21 can be pushed back into the storage case 26. At this time, as shown in FIG. 25, the second end of the first pipe 23 is connected to the inlet end 222 of the input pump 22.

The dosing pump 22 may be a plunger pump or another type of pump such as a vane pump, and the specific type can be determined according to the actual situation.

In some embodiments, as shown in FIG. 25, the second dispenser 2 further includes a valve 27. The valve 27 is arranged to open and close the first pipeline 23. As shown in FIG. 28, the valve 27 can be closed when the second detergent box 21 is pulled out of the storage case 26. This makes it possible to prevent the detergent in the second detergent box 21 from spilling out of the second detergent box 21 along the first pipeline 23.

The type of valve 27 is not exclusive, and in some embodiments, the valve 27 may be a solenoid valve that controls the opening and closing of the valve 27 via a controller.

In some other embodiments, the valve 27 may be a mechanical check valve. Specifically, as shown in Figures 28, 29, and 30, Figure 29 is a partially enlarged view of the valve in Figure 25. Figure 30 is a three-dimensional structural view of the valve 27. The valve 27 includes a valve body 271, a valve spool 275, and an elastic member 276.

The valve body 271 includes a valve cavity 272, and a valve inlet 273 and a valve outlet 274 that communicate with the valve cavity 272. The valve body 271 is fitted into the first pipeline 23, and the valve outlet 274 is located at the second end of the first pipeline 23 (the upper end of the first pipeline 23 in FIG. 28). The valve spool 275 is provided in the valve cavity 272 and is located at the valve outlet 274 so as to close the valve outlet 274.

Specifically, as shown in FIG. 29, the size of the valve cavity 272 is larger than the size of the valve outlet 274 along the radial direction of the first pipe 23. The valve spool 275 enters the valve outlet 274 by the action of the elastic member 276 and fits into the valve outlet 274 to close the valve outlet 274.

The elastic member 276 is arranged to apply a restoring force to the valve spool 275 that drives the valve spool 275 to move in the direction of the valve outlet 274. The elastic member 276 may be a spring. As shown in FIG. 29, one end of the spring is connected to the end cap 2712 and the other end is connected to the valve spool 275. Of course, in addition to a spring, the elastic member 276 may be an elastic piece or the like.

23 and 29, the dosing pump 22 further includes an abutment post 225 provided at the inlet end 222. The dosing pump 22 is arranged such that when the second detergent box 21 is located in the storage case 26, the abutment post 225 is inserted into the valve outlet 274 from the second end of the first pipe 23, and pushes the valve spool 275 to move in a direction approaching the valve inlet 273, causing the valve spool 275 to open the valve outlet 274 and connect the first pipe 23 to the inlet end 222.

As shown in FIG. 28, when the second detergent box 21 is pulled out of the storage case 26, the valve spool 275 is located at the valve outlet 274 and closes the valve outlet 274. At this time, the detergent in the second detergent box 21 cannot overflow to the outside of the second detergent box 21 through the valve 27. As shown in FIG. 25, when the second detergent box 21 is pushed back into the storage case 26, the abutment column 225 pushes the valve spool 275 to move it in a direction approaching the valve inlet 273 (i.e., to the right), causing the valve spool 275 to open the valve outlet 274. At this time, the input pump 22 can extract the detergent in the second detergent box 21 through the first pipe 23.

In some embodiments, to facilitate maintenance or replacement of components within the valve cavity 272 of the valve 27, as shown in FIG. 30, the valve body 271 includes a sleeve 2711 and an end cap 2712 removably attached to a first end port of the sleeve 2711 (the lower end port in the figure). The valve spool 275 is disposed within the sleeve 2711, and the second end port of the sleeve 2711 (the upper end port in the figure) is the valve outlet 274, and the valve inlet 273 is disposed in the end cap 2712. Since the end cap 2712 is removably connected to the sleeve 2711, if the valve spool 275 or the elastic member 276 is damaged, the end cap 2712 can be removed from the sleeve 2711 to facilitate maintenance or replacement of the valve spool 275 and the elastic member 276.

In some embodiments, to more firmly install the valve 27 in the first conduit 23, as shown in Figs. 29 and 30, the valve 27 further includes a locking claw 277 provided on the end cap 2712. A locking portion 235 is provided on the inner wall of the first conduit 23, and the locking claw 277 engages with the locking portion 235. This can prevent the valve 27 from moving along the first conduit 23, and more firmly install the valve 27 in the first conduit 23.

In some embodiments, to improve the seal between the outer wall of the valve body 271 and the inner wall of the first conduit 23, as shown in Figures 29 and 30, the valve 27 further includes a seal ring 278. An attachment ring groove 2713 is formed in the outer wall of the valve body 271. The seal ring 278 is provided in the attachment ring groove 2713 to seal between the valve body 271 and the inner wall of the first conduit 23. By providing the seal ring 278 between the outer wall of the valve body 271 and the first conduit 23, the seal between the valve body 271 and the first conduit 23 can be improved to prevent liquid leakage between the valve 27 and the first conduit 23.

In some embodiments, in order to facilitate cleaning of the inside of the first pipeline 23, it is installed as shown in Figs. 29 and 31. Fig. 31 is a structural diagram of the first pipeline 23. A connection flange 236 is provided at the second end (the upper end in Fig. 31) of the first pipeline 23. The second end of the first pipeline 23 is inserted into the mounting hole 212. The connection flange 236 is located outside the second detergent box 21 and is removably connected to the box wall of the second detergent box 21. For example, the connection flange 236 is connected to the box wall of the second detergent box 21 by a screw.

By removably connecting the first pipeline 23 and the second detergent box 21, when it is necessary to clean the inside of the first pipeline 23, the first pipeline 23 can be removed from the second detergent box 21, making it easy for the user to clean the first pipeline 23.

In some embodiments, in order to more firmly connect the connection flange 236 and the second detergent box 21, as shown in FIG. 29, a mounting groove 213 is opened in the box wall of the second detergent box 21 near the input pump 22, a mounting hole 212 is opened in the groove bottom of the mounting groove 213 (i.e., the groove wall opposite the groove mouth of the mounting groove 213), and the connection flange 236 is located in the mounting groove 213. By providing the connection flange 236 in the mounting groove 213, the mounting groove 213 can perform a certain position limiting function for the connection flange 236 and can limit the movement of the connection flange 236 in the radial direction of the mounting hole 212, thereby making the connection between the connection flange 236 and the second detergent box 21 stronger.

In some embodiments, to improve the sealing between the first pipeline 23 and the box wall of the second detergent box 21, as shown in Figures 28 and 29, the second input device 2 further includes a pipe seal member 28. The pipe seal member 28 includes a seal sleeve 281 and a seal flange 282 provided at one end of the seal sleeve 281 and extending in the radial direction of the seal sleeve 281.

The sealing sleeve 281 is provided between the first pipe 23 and the wall of the mounting hole 212. The sealing flange 282 is located outside the mounting hole 212 and between the connection flange 236 and the box wall of the second detergent box 21.

By providing the pipe seal member 28, it is possible to better seal between the outer wall of the first pipeline 23 and the mounting hole 212, and between the box wall of the second detergent box 21 and the connection flange 236, and it is possible to prevent the detergent in the second detergent box 21 from leaking from the gap between the outer wall of the first pipeline 23 and the mounting hole 212, and the gap between the box wall of the second detergent box 21 and the connection flange 236.

In some embodiments, the installation is as shown in Figures 28 and 32. Figure 32 is a schematic diagram of the second detergent box 21 removed from the first pipeline 23. The first pipeline 23 includes a horizontal pipe section 231 that is installed horizontally and an inclined pipe section 232 that is installed at an angle to the horizontal plane. One end of the horizontal pipe section 231 is connected to the mounting hole 212, and the other end is connected to the inclined pipe section 232. One end of the inclined pipe section 232 that is away from the horizontal pipe section 231 extends toward the bottom of the second detergent box 21.

Since one end of the inclined pipe section 232 of the first pipe line 23 extends toward the bottom of the second detergent box 21, the distance between the opening of the inclined pipe section 232 and the bottom of the second detergent box 21 can be reduced. This allows the detergent in the second detergent box 21 to be sufficiently drawn out by the first pipe line 23, improving the efficiency of detergent use in the second detergent box 21 and avoiding the need to frequently add liquid detergent.

As shown in FIG. 29, the locking portion 235 that engages with the locking claw 277 may be located at the position where the horizontal pipe portion 231 and the inclined pipe portion 232 are connected.

In some embodiments, the pump cavity 221 and the second conduit 24 of the injection pump 22 are installed as shown in FIG. 24 and FIG. 33 to facilitate cleaning. FIG. 33 is a cross-sectional view of the G-G section in FIG. 11. The injection pump 22 includes a communication port 224 communicating with the pump cavity 221. The communication port 224 and the outlet end 223 of the injection pump 22 are both located lower than the water diversion assembly 13. The second injection device 2 further includes a third conduit 25. A first end of the third conduit 25 communicates with one of the water diversion cavities 131 (see FIG. 1), and a second end of the third conduit 25 communicates with the communication port 224. Since the communication port 224 and the outlet end 223 of the injection pump 22 are both located lower than the water diversion assembly 13, the water in the water diversion cavity 131 has a gravitational potential with respect to the communication port 224 and the outlet end 223. As a result, the water in the water diversion cavity 131 flows by gravity along the third line 25 from the communication port 224 into the pump cavity 221 of the input pump 22, and then flows from the outlet end 223 of the input pump 22 into the second line 24, cleaning the pump cavity 221 of the input pump 22 and the second line 24, and preventing detergent from remaining in the pump cavity 221 and the second line 24.

In some embodiments, as shown in Figs. 14 and 33, the water distribution assembly 13 further includes a connecting pipe 139 located below the water distribution plate 132 and extending vertically to facilitate communication between the third pipeline 25 and the water distribution cavity 131. The upper end of the connecting pipe 139 communicates with one of the water distribution cavities 131, and the lower end protrudes from the storage box 11 and enters the pipe mouth of the first end of the third pipeline 25. By providing the connecting pipe 139 in this manner, if the third pipeline 25 is damaged, the third pipeline 25 can be easily removed from the water distribution assembly 13, thereby facilitating repair, maintenance, and replacement of the third pipeline 25.

As shown in Figs. 10 and 33, a pipe 126 extending vertically is provided inside the storage box 11. The lower end of the pipe 126 communicates with the outside of the storage box 11. The lower end of the connection pipe 139 passes through the pipe 126 and extends to the outside of the storage box 11.

In some embodiments, as shown in FIG. 26, in order to make it easier for the user to pull out the second detergent box 21 from the storage case 26, the front wall 214 of the second detergent box 21 is located outside the storage case 26, and the top end of the front wall 214 is positioned to protrude from the top surface of the storage case 26. This allows the user to easily pull out the second detergent box 21 from inside the storage case 26 by applying a force to the top end of the front wall 214 of the second detergent box 21.

Of course, as shown in FIG. 26, the bottom end of the front wall 214 of the second detergent box 21 may also be provided to protrude from the bottom surface of the storage case 26. Similarly, the user can easily pull out the second detergent box 21 from inside the storage case 26 by applying a force to the bottom end of the front wall 214 of the second detergent box 21.

For ease of explanation, the direction of movement of the second detergent box 21 when it is pulled out of the storage case 26 is referred to as "front," and the direction of movement of the second detergent box 21 when it is pushed into the storage case 26 is referred to as "rear." The above terms "front," "rear," etc. indicate directionality and do not indicate or imply that the device being referred to has a specific orientation.

To make it easier for the user to judge the amount of detergent in the second detergent box 21, as shown in FIG. 23, the front wall 214 of the second detergent box 21 includes a transparent area 2141. A capacity scale line 2142 is provided in the transparent area 2141, and the user can judge the amount of detergent added from the relationship between the detergent liquid level and the capacity scale line 2142, and control the amount of detergent added to the second detergent box 21. The user can also judge the remaining amount of detergent in the second detergent box 21 via the capacity scale line 2142. If there is too little detergent, more detergent can be added at the appropriate time.

In some embodiments, as shown in FIG. 23, a groove 261 is provided at the bottom of the storage case 26. The groove 261 is generally U-shaped, but is not limited to a U-shape and may be other shapes. The groove 261 is used to store remaining detergent and prevent the remaining detergent from flowing around inside the storage case 26. This remaining detergent is detergent other than the detergent in the second detergent box 21, for example, detergent that has flowed out while the second detergent box 21 is being pushed in or pulled out, or detergent that has overflowed from the second detergent box 21 itself.

23 and 28, in order to facilitate cleaning of the inside of the second detergent box 21, the second detergent box 21 includes a box body 215 having a box mouth at the top end and a top cap 216 that is removably attached to the box mouth of the box body 215. The input port 211 is opened in the top cap 216. By providing the second detergent box 21 with a removable box body 215 and top cap 216, on the one hand, it is easy for the user to remove and clean it by himself, and the user can remove the top cap 216 from the box body 215 to clean it or replace the solution remaining in the box body 215, which meets the user's needs for cleaning and replacement and improves the user's experience; on the other hand, because the top cap 216 is removable, the user can insert a sufficient amount of detergent product into the box body 215 at one time by removing the top cap 216, which meets the user's need for inserting a large amount of detergent product.

The inlet 211 may be circular, elongated, polygonal, etc., and is not specifically limited here.

In some embodiments, as shown in FIG. 28, a seal member 217 is provided between the box body 215 and the top cap 216 to prevent the detergent from spilling out between the top cap 216 and the box body 215. Here, the seal member 217 may be one or more combinations of a sealing ring, a gasket, and a sealing strip. By providing the seal member 217, a seal is achieved between the box body 215 and the top cap 216, and the detergent added to the box body 215 is prevented from spilling out.

In some embodiments, as shown in FIG. 28 and FIG. 34, FIG. 34 is a three-dimensional structure diagram of the second detergent box 21. The second detergent box 21 further includes a flip cap 218 that is installed to cover the inlet 211. The flip cap 218 is free at one end and hinged at the edge of the inlet 211 at the other end so that the inlet 211 can be opened. When detergent needs to be added to the box body 215, the flip cap 218 is opened and the detergent is added through the inlet 211. After the detergent is added, the flip cap 218 is closed to close the inlet 211. This can prevent the detergent from flying out of the inlet 211 and being wasted during the process of pushing the second detergent box 21 into the storage case 26.

In some embodiments, as shown in FIG. 27, the top cap 216 is further provided with a recess 2161 to facilitate the user opening the flip cap 218. The recess 2161 is provided at the free end of the flip cap 218, and a portion of the recess 2161 is located below the free end of the flip cap 218. This allows the user to insert their hand below the free end of the flip cap 218 through the recess 2161, making it easier to open the flip cap 218.

In some embodiments, as shown in FIG. 28, the second detergent box 21 further includes a flow guide member 219 to ensure smooth detergent injection into the box body 215. The flow guide member 219 is provided at the inlet 211 and is arranged to guide the detergent into the box body 215. By providing the flow guide member 219 at the inlet 211, the detergent can be made to flow into the box body 215 along the flow guide member 219, and the detergent can be prevented from splashing out due to reasons such as an excessively fast injection speed.

The structure of the flow guide member 219 is not unique, and in some embodiments, as shown in FIG. 28, the flow guide member 219 is a flow guide plate. One edge of the flow guide plate is connected to the edge of the inlet 211, and the flow guide plate extends into the box body 215.
