That is, in this more specific embodiment, when the solution dispensing pump 200 is operated, the solution in the corresponding solution storage portions 117, 118 of the box body 110 is extracted through the liquid delivery pipes 167, 168 on the box cover 160 connected to the solution inlet pipes 211, 221, as shown in fig. 11, which exemplarily shows that when the solution dispensing pump 200 is operated, the pump body 210 thereof is fluidly connected to the liquid delivery pipe 167 on the box cover 160 through the solution inlet pipe 211, and the solution in the solution storage portion 117 is extracted through the liquid delivery pipe 167.

Therefore, in this more specific embodiment, since no water path is required to be provided on the box cover 160, a double-layer structure is not required, thereby reducing material usage and manufacturing cost; meanwhile, hot plate welding is not needed, so that parts welded by hot plates are reduced, and the manufacturing cost is further reduced; moreover, the box cover is mainly used for reinforcing and mounting, and a waterway tightness test and a water leakage test are not required to be carried out on the box cover, so that the detection cost and the procedures are thoroughly saved, and the waste of a large amount of materials related to unqualified tests is avoided and can also be reduced; in addition, the box cover part can be directly formed by injection molding, secondary processing is not needed, the qualified rate of the part is correspondingly increased, and material and cost waste caused by defective products is reduced.

Further, as shown in fig. 1, the solution dispensing pump 200 may be installed on the case body 110 or the case cover 160. By installing the solution dosing pump 200 in this manner, a more compact design of the entire automatic dosing device 10 can be achieved. In addition, since the case body 110 and the case cover 160 fixed on the case body 110 are both fixedly installed instead of movably installed, it is not necessary to keep the connection between the solution storage parts 117 and 118 and the solution feeding pump 200 in a separated state at any operation stage of the automatic liquid adding device 10, that is, the connection state between the solution feeding pump 200 and the solution storage parts 117 and 118 is always kept unchanged, more specifically, the connection state between the solution inlet pipes 211 and 221 of the pump bodies 210 and 220 of the solution feeding pump 200 and the corresponding solution storage parts 117 and 118 is always kept unchanged, thereby preventing the fluid leakage problem caused by the separated state.

In a more specific embodiment, as shown in fig. 7 and 11, the feeding pipes 167, 168 provided on the box cover 160 each include a vertical pipe portion 177, 178 extending perpendicularly with respect to the main face 161 of the box cover 160, the free ends of the vertical pipe portions 177, 178 extend into the corresponding solution storage portion 117, 118, for example, to the near bottom of the corresponding solution storage portion 117, 118, and the vertical pipe portions 177, 178 are connected to the corresponding first openings 163, 164 opened to the side of the box cover 160, and the solution inlet pipes 211, 221 of the solution feeding pump 200 may be in fluid communication with the vertical pipe portions 177, 178 through the corresponding first openings 163, 164, so as to draw the solution from the corresponding solution storage portion 117, 118 through the vertical pipe portions 177, 178. More specifically, as shown in fig. 7, the infusion pipes 167, 168 each further comprise a transverse portion 175, 176 connected between the first opening 163, 164 and its vertical pipe portion 177, 178, respectively, which transverse portions 175, 176 may be used, for example, to rest the solution inlet pipes 211, 221 of the solution dosing pump 200. The solution feeding pipes 167 and 168 are thus provided, which is simple in structure and easy to manufacture, and the solution inlet pipes 211 and 221 of the solution feeding pump 200 are connected through the first openings 163 and 164 provided in the side surface of the box cover 160, allowing for a more compact overall structure, and making the installation of the solution feeding pump 200 more stable without coming loose due to vibration or the like during the use of the washing machine.

More specifically, as shown in fig. 10 and 12, at least one second opening, two second openings 131, 132 are shown in the first tank sidewall 111, for example, adjacent the third tank sidewall 113 and adjacent the upper end 125 of the tank 110, and each solution outlet pipe 212, 222 of the solution dosing pump 200 is in fluid communication with the water inlet channel 119 through the corresponding second opening 131, 132. Such an arrangement makes it easy to communicate the solution outlet pipes 212, 222 of the solution dosing pump 200 to the water intake channel 119, while, as mentioned above, allows for a more compact overall structure and makes the installation of the solution dosing pump 200 more stable.

In a more specific embodiment of the automatic filling device 10 according to the present invention, as shown in fig. 2A, 10 and 12, the first box sidewall 111 is further provided with at least one third opening, for example, two third openings 143, 144 are shown, for example, disposed near the third box sidewall 113, the first partition wall 121 is provided with fourth openings 153, 154 corresponding to each third opening 143, 144, wherein, in the assembled state of the automatic filling device 10, each of the third openings 143, 144 and the corresponding fourth openings 153, 154 are aligned with the corresponding first openings 163, 164 provided on the cartridge cover 160, the respective solution inlet pipes 211, 221 for the solution dosing pump 200 are in fluid communication with the vertical pipe portions 177, 178 provided on the box cover 160 through the respective third openings 143, 144, fourth openings 153, 154 and respective first openings 163, 164. Such an arrangement further allows for a compact overall structure and makes the solution dosing pump 200 more robust to installation and less prone to loosening due to vibration and the like during use of the washing machine.

In a more specific embodiment of the automatic liquid adding device 10 according to the present invention, as shown in fig. 8, 9-11 and 13, the automatic liquid adding device 10 further comprises a dispenser 300 for dispensing a solution into the solution storage parts 117, 118 in the cartridge body 110, for which purpose the dispenser 300 is provided with at least one solution adding part 310, 320, each solution adding part 310, 320 comprising a solution adding port 311, 321 for adding a solution and a solution dispensing port 321, 322 in fluid communication with the corresponding solution storage part 117, 118 and dispensing a solution thereto. For example, as shown, the dispenser 300 is provided with two solution adding parts 310, 320 spaced apart from each other, the two solution adding parts 310, 320 being used to add the same or different solutions, and each solution adding part 310, 320 being in fluid communication with a corresponding one of the solution storage parts 117, 118. Such an arrangement allows different solutions, for example different kinds of detergents with different functions, to be conveniently used according to the needs of the user.

In order to mount the dispenser 300 in a compact and movable manner, in a more specific embodiment, first hole grooves 135, 136 are provided in the side walls of the case body, and the solution adding parts 310, 320 of the dispenser 300 can be inserted into the case body 110 and pulled out of the case body 110 through the corresponding first hole grooves 135, 136, respectively. For example, the first hole grooves 135, 136 are provided near the upper end 125 of the cartridge body 110 to ensure that the solution adding parts 310, 320 are higher than the bottom walls of the solution storage parts 117, 118, thereby allowing more spacious space of the solution storage parts 117, 118, which can be used for storing the solution.

That is, in this more specific embodiment, as shown in fig. 9, when the user needs to add the solution, the dispenser 300 is drawn out of the cartridge body 110 until the solution adding ports 311, 321 of the solution adding parts 310, 320 are exposed outside the cartridge body 110, and at this time, the solution dispensing ports 321, 322 are still located inside the cartridge body 110 and are in fluid communication with the solution storage parts 117, 118. Thus, the user pours the solution into the solution adding parts 310, 320 through the solution adding ports 311, 321, the solution flows along the bottom of the solution adding parts 310, 320 to the solution distributing ports 321, 322 and flows therefrom into the solution storing parts 117, 118 of the cartridge 110, as shown by the arrow direction in fig. 10, where the flow direction of the solution is exemplarily shown only by the solution added to one solution adding part 310 from the solution adding port 311 of the solution adding part 310 and then flows into the corresponding one solution storing part 117 along the bottom of the solution adding part 310; it should be understood that the principles and processes are equally applicable to other solution additions. Further, for example, the solution addition operation is completed when the user stops adding solution after the user has added solution to the warning position or has added the desired or given amount and pushes the dispenser 300 to the closed position. Optionally, level sensors (not shown) are provided in the solution reservoirs 117, 118 to sense the liquid level therein and to issue an alarm when an alert position is reached.

Thus, in this embodiment, the dispenser 300 is removably mounted, and more particularly, drawable mounted, so that the addition of solution to the solution storage portions 117, 118 can be accomplished with a relatively small and lightweight dispenser 300, and the user draws the dispenser addition solution relatively laborsavingly to facilitate the user's addition of solution after drawing the dispenser.

After the addition of the solution to the solution reservoirs 117, 118 is complete, the solution dosing pump 200 operates as described above and the flow of influent water, solution and mixtures thereof is as shown in fig. 11-13.

In a more specific embodiment, as shown in fig. 8, 9 and 15, the dispenser 300 further includes one or more powder adding parts, which are illustrated as a powder adding part 330, and a second hole 137 is correspondingly formed in the sidewall of the case, the powder adding part 330 can be inserted into the case 110 and pulled out from the case 110 through the second hole 137, and when the powder adding part 330 is inserted into the case 110, the powder adding part 330 is located above the water outlet 116 of the case 110, and the water inlet 119 of the case 110 can be opened to the upper part of the powder adding part 330. More specifically, as shown in fig. 8 and 14 to 15, the cover 160 further includes a shower portion 171, the shower portion 171 is located above the powder adding portion 330 in an assembled state of the automatic liquid adding apparatus 10, that is, in a state where the cover 160 is fixed to the case body 110 and the dispenser 300 is inserted, and the shower portion 171 is provided with an open water inlet portion 172 in fluid communication with the water inlet passage 119. Preferably, in order to facilitate easy access of the powder by the inflow water, as shown in fig. 8, the bottom of the powder addition part 330 is set lower, for example, lower than the bottoms of the solution addition parts 310, 320.

Thus, the powder adding part 330 allows a user to conveniently use a powdered detergent, such as washing powder. When the user needs to add powder, the dispenser 300 is pulled out of the box body until the powder adding portion 330 is exposed outside the box body 110 (as shown in fig. 8), and the user pushes the dispenser 300 to the closed position after pouring powder into the powder adding portion 330. At this time, as shown in fig. 14 to 15, the water inlet end 122 of the water inlet channel 119 starts to feed water, the water flows to the powder adding part 300 through the water inlet channel 119, preferably flows to the powder adding part 300 through the spraying part 171 of the box cover 160, and washes the powder therein into the water outlet part 116 of the box body 110 below the powder adding part 330 and the water outlet 120 thereof to flow into the washing tub of the washing machine, as shown by arrows in fig. 15, wherein the powder is schematically shown by a dot at the bottom of the powder adding part 330 in fig. 15. This arrangement makes the entire automatic filling device 10 more compact and enables automatic addition and dosing of powder with a simple construction.

Preferably, the spraying part 171 is provided with spraying holes 173, such as regularly arranged spraying holes. Therefore, the water in the water inlet channel 119 can flow to the spraying part 171 through the water inlet part 172 of the spraying part 171 on the box cover 160, and fall into the powder adding part 330 through the spraying holes 173, and the powder in the water can be mixed and then flushed into the water outlet part 116 of the box body 110 and flow out into the washing tub of the washing machine through the water outlet 120. Such an arrangement makes it possible to flush the powder in the powder addition part 330 more uniformly by the inflow of water, and to control the water pressure flowing to the powder addition part 330, thereby preventing sputtering, making the powder use more effective.

In a more specific embodiment, as shown in fig. 2, 4 and 10, the at least one first hole groove 135, 136 and the second hole groove 137 are provided on the second case sidewall 112 opposite to the first case sidewall 111 among the case sidewalls. This arrangement facilitates a compact construction of the automatic filling device 10 while also ensuring the strength of the side walls of the cartridge.

In a more specific embodiment of the automatic filling device 10 according to the present invention, as shown in fig. 8, the dispenser 300 is a unitary piece. This allows for simpler design and manufacture of the dispenser 300, ease of assembly, and overall stability.
