[0024] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0025] like Figure 1-Figure 5 As shown, a water inlet box assembly and a washing machine are provided, the water inlet box assembly includes a water inlet box 1 and a drawer-type washing powder box 2, a stirring assembly 3 for stirring and dissolving washing powder is arranged in the washing powder box 2, a water inlet 101 is arranged on the water inlet box 1, the stirring assembly 3 includes a stirring wheel 301, the central axis of the water inlet 101 intersects with the outer contour of the stirring wheel 301, and the external water flow rushes toward the outer contour of the stirring wheel 301 through the water inlet 101, so that the stirring wheel 301 rotates in the washing powder box 2.

[0026] Specifically, when water flows in from the water inlet 101, it directly impacts the outer contour of the stirring wheel 301, and has a direct driving force on the stirring wheel 301 to rotate, thereby stirring the washing powder in the washing powder box 2, accelerating the dissolution to form foam. The water flow directly drives the stirring wheel 301 to rotate and stir the washing powder, so that the washing powder can be dissolved faster before the washing machine washes clothes, forming more foam, reducing residue and further improving the cleaning effect of the washing machine.

[0027] It should be pointed out that in addition to laundry detergent, the water inlet box assembly can also be filled with laundry liquid, softener, disinfectant, etc., to increase the functionality and convenience of the washing machine.

[0028] Further, if Figure 2 As shown, a plurality of stirring blades 3011 are provided on the stirring wheel 301 , and the outer periphery of the stirring blades 3011 intersects with the central axis of the water inlet 101 .

[0029] Specifically, when water flows in from the water inlet 101, it directly acts on each stirring blade 3011, pushing the stirring wheel 301 to rotate. Under the action of the stirring blade 3011, the washing powder quickly dissolves and forms foam with the water flow, thereby improving the washing ability of the laundry detergent; the stirring blade 3011 can more effectively destroy the clumping structure of the washing powder, causing it to quickly dissolve in the water to form a uniform washing solution.

[0030] Further, if Figure 2 and Figure 3 As shown, a connecting shaft 3012 is provided in the middle of the stirring wheel 301 , and a plurality of stirring blades 3011 are evenly spaced along the axial direction of the connecting shaft 3012 .

[0031] Specifically, the design of the connecting shaft 3012 and the evenly spaced stirring blades 3011 can optimize the dynamic effect of the water flow, ensuring that the impact force of the water flow on each stirring blade 3011 is more uniform, so that the water flow can more effectively drive the stirring wheel 301 to rotate, further improving the washing effect.

[0032] Further, if Figure 2 and Figure 3 As shown, the stirring assembly 3 also includes a pin shaft 302 that is connected to the connecting shaft 3012 , and the pin shaft 302 and the connecting shaft 3012 are clearance-matched.

[0033] Specifically, the stirring assembly 3 includes a stirring wheel 301 , a connecting shaft 3012 and a pin 302 . The pin 302 and the connecting shaft 3012 are clearance-fitted to ensure that the stirring blade 3011 can effectively rotate when impacted by water flow.

[0034] Further, if Figure 2 , Figure 3 and Figure 5As shown, a positioning step 3021 is provided on one end of the pin shaft 302, and the pin shaft 302 abuts against one end of the connecting shaft 3012 through the positioning step 3021; ​​an elastic buckle 3022 is provided on the other end of the pin shaft 302, and an opening 201 is provided on the washing powder box 2. After the elastic buckle 3022 of the pin shaft 302 passes through the opening 201, the elastic buckle 3022 is snapped onto the edge of the opening 201.

[0035] Specifically, the positioning step 3021 at one end of the pin 302 abuts against one end of the connecting shaft 3012, which can ensure that the pin 302 remains stable during the stirring process to prevent the stirring effect from being affected by loosening; the elastic buckle 3022 design at the other end of the pin 302 allows the pin 302 to easily pass through the opening 201 on the washing powder box 2 and be snapped onto its edge, so that users can easily install and disassemble it, which is convenient for cleaning and maintenance.

[0036] Further, if Figure 2 , Figure 3 and Figure 5 As shown, a groove 202 is provided on the washing powder box 2 , the water inlet 101 is arranged corresponding to the groove 202 , and the stirring wheel 301 is at least partially located on the groove 202 .

[0037] Specifically, by providing a groove 202 on the washing powder box 2 and arranging the water inlet 101 corresponding to the groove 202, the water flow guidance can be optimized, so that the water flow acts more concentratedly on the stirring wheel 301, thereby improving the water flow utilization efficiency; the stirring wheel 301 is at least partially located on the groove 202, so that the stirring wheel 301 can be more directly impacted by the water flow, thereby enhancing the stirring effect and accelerating the dissolution of the washing powder.

[0038] Further, if Figure 2 As shown, the washing powder box 2 is provided with a water outlet 203 for discharging the washing powder stirred by the stirring wheel 301 , and the height H1 of the water outlet 203 is higher than the height H2 of the water inlet 101 .

[0039] Specifically, the height H1 of the water outlet 203 is higher than the height H2 of the water inlet 101, which can effectively prevent the detergent solution that has been dissolved by the stirring wheel 301 from flowing back to the unstirred area, ensuring that the detergent is fully dissolved; the height difference design enables the water flow to be quickly discharged after being stirred by the stirring wheel 301, and enter the inner barrel of the machine body through the water outlet 203, reducing the possibility of insufficient dissolution and improving the washing effect.

[0040] Further, if Figure 2As shown, a water inlet column 1011 extending toward the washing powder box 2 is provided at the water inlet 101, and a water inlet portion 204 corresponding to the water inlet column 1011 is provided on the washing powder box 2. A guide slope 1011a is provided on the end of the water inlet column 1011, and the water inlet column 1011 is inserted into the water inlet portion 204 through the guide slope 1011a.

[0041] Specifically, by providing a water inlet column 1011 extending toward the washing powder box 2 at the water inlet 101, and providing a corresponding water inlet portion 204 on the washing powder box 2, the accuracy of water inlet can be ensured, water overflow can be prevented, and water utilization efficiency can be improved; the guiding slope 1011a at the end of the water inlet column 1011 can guide the water flow to enter the washing powder box 2 more smoothly, so that the water flow can be more accurately aligned with the stirring impeller 301, forming a stronger water flow impact on the stirring impeller 301, and making the docking of the water inlet column 1011 and the water inlet portion 204 easier, and the user can easily complete the installation and disassembly.

[0042] Further, if Figure 2 and Figure 3 As shown, a stirring chamber 4 is formed between the water inlet box 1 and the washing powder box 2 .

[0043] Specifically, the stirring chamber 4 enclosed between the water inlet box 1 and the washing powder box 2 provides a special stirring space, so that the water flow and the washing powder are fully mixed in a relatively closed environment, further improving the dissolution efficiency of the washing powder; the water flow enters the stirring chamber 4 through the water inlet column 1011, and the stirring wheel 301 rotates under the action of the water flow, and the stirring blades 3011 evenly distribute the washing powder in the stirring chamber 4, ensuring the rapid dissolution of the washing powder.

[0044] A washing machine comprises a machine body, on which the water inlet box assembly is arranged.

[0045] Specifically, there is an inner drum and a driving component that drives the inner drum to rotate within the machine body. The water inlet box component is arranged on the top or front panel of the machine body, so that the user can add washing powder, detergent and softener conveniently. The water will pass through the water inlet box component, dissolve the washing powder, detergent and softener and bring them into the inner drum, further improving the cleaning effect of the washing machine. The inner drum can realize the functions of washing, rinsing and spinning clothes through the driving component.
