Description

Technical Field

[0001] The present invention belongs to the technical field of washing machines, and particularly relates to a water inlet box assembly of a washing machine and a washing machine having the water inlet box assembly. Background Art

[0002] A drum washing machine is equipped with a water inlet box assembly at the top of the casing, which is used to fill the washing machine with water and to dispense detergent and softener. The water inlet box assembly includes a water box and a removable detergent box housed within the water box. The water box includes an upper cover and a lower shell, which are separately injection molded and then installed. A seal is required between the upper cover and the lower shell. A water diversion plate is provided below the upper cover, forming a water inlet cavity between the upper cover and the diversion plate. The washing machine's water inlet pipe is connected to the water inlet cavity, and a water inlet hole is provided on the diversion plate. The washing machine's water inlet pipe is provided with an inlet valve. Since the water inlet cavity is located on the upper cover, a water inlet hose is generally provided between the inlet valve and the water inlet cavity. Current water inlet box assemblies have many components, which increases both manufacturing and assembly costs.

[0003] The water flow path into the water inlet box assembly is generally from top to bottom. After opening the water inlet valve, tap water enters the water inlet chamber through the water inlet pipe, spills into the detergent box through the water inlet hole, and then falls into the detergent storage chamber, where the detergent in the detergent box dissolves and flows into the water inlet box, finally entering the washing tub. In other words, all incoming water must flow through the water inlet chamber, then into the detergent storage chamber, and finally into the water box. This makes the water flow path in the water inlet box assembly longer, extending the water filling time.

[0004] The above information disclosed in this background technology is only used to increase the understanding of the background technology of this application. Therefore, it may contain information that does not constitute the prior art known to ordinary technicians in this field. Summary of the Invention

[0047] See also Figures 1-15 , is an embodiment of the water inlet box assembly for a washing machine proposed by the present invention. A water inlet box assembly 100 for a washing machine includes: a water box 10 and a detergent box 20. The water box 10 is fixedly mounted within the washing machine and connected to the washing machine's water inlet pipe to enable water to be injected into the washing tub. The water box 10 is integrally formed and surrounds a cavity with an open front. The detergent box 20 is retractable and accommodated within the water box 10. A detergent holding chamber 21 is provided within the detergent box 20 for storing detergent. Water enters the detergent holding chamber 21 to dissolve and dilute the detergent before flowing into the washing tub. A mounting plate 30 is fixedly mounted within the water box 10. The water box 10 is integrally formed, and a limiting structure cannot be provided on the water box 10. Therefore, the mounting plate 30 is provided to limit the withdrawal of the detergent box 20. A limiting structure is provided between the mounting plate 30 and the detergent box 20 to limit the withdrawal of the detergent box 20.

[0048] Providing an integrally formed water box 10 is beneficial to reducing the number of components of the water inlet box assembly 100, reducing the installation of the water box upper cover and the lower shell, which is beneficial to improving assembly efficiency, reducing manufacturing costs, and ensuring the sealing of the water box 10; providing a mounting plate 30 to limit the pulling and pulling of the detergent box 20 into place.

[0049] See also Figure 6-Figure 8 As shown, the water box 10 is provided with a plurality of first guide grooves 15 arranged in the front-to-back direction, and the mounting plate 30 is provided with a first guide rail 31 that matches the first guide grooves 15. The first guide grooves 15 are located within the first guide rail 31. The first guide grooves 15 are used to support the mounting plate 30 and enable sliding assembly and installation of the mounting plate 30 in the front-to-back direction. A fastening hole 19 is provided on the top plate of the water box 10, and a fastening groove 32 that matches the fastening hole 19 is provided on the mounting plate 30. Fasteners are used to secure the fastening holes 19 and the fastening grooves 32. That is, when the mounting plate 30 is assembled and secured, the first guide grooves 15 and the first guide rail 31 cooperate to push the mounting plate 30 backward into place, so that the first guide grooves 15 support the mounting plate 30. The fasteners are then passed through the fastening holes 19 and fastened to the fastening grooves 32 to secure the mounting plate 30.

[0050] The detergent box 20 is provided with outwardly extending first hems 22 on its left and right sides. A second hem 18 extending outward and matching the first hems 22 is provided within the water box 10. The first hem 22 is retractably positioned on the second hem 18. The retractable positioning of the first hem 22 on the second hem 18 facilitates the removal of the detergent box 20 from the water box 10. A downwardly extending lower edge plate 33 is provided on the mounting plate 30. The lower edge plate 33 is positioned above the second hem 18, with the first hem 22 positioned between the lower edge plate 33 and the second hem 18. The provision of the lower edge plate 33 allows the first hem 22 to move back and forth within the space defined by the lower edge plate 33 and the second hem 18, facilitating smooth removal of the detergent box 20 and preventing shaking during removal.

[0051] The detergent box 20 has at least two detergent holding chambers 21. One of the detergent holding chambers 21 has a first sidewall 215 adjacent to the other adjacent detergent holding chamber 21. An upper edge 216 extends upward along the first sidewall 215 to form a top edge 216. The top edge 212 prevents wash water from overflowing from the detergent holding chamber 21 and flowing into the adjacent detergent holding chamber 21. The top edge 216 is higher than the overflow level of the other detergent holding chamber 21 and the top edge 216 is higher than the top edge of the wall of the other detergent holding chamber 21. Specifically, the detergent holding chamber 21 of the detergent box 20 includes a laundry liquid holding chamber 211 and a softener holding chamber 212, each adjacent to the other. The softener holding chamber 212 has a sidewall 215 adjacent to the laundry liquid holding chamber 211, and the top edge 216 is provided to prevent the detergent water from overflowing from the laundry liquid holding chamber 211 and flowing into the softener holding chamber 212.

[0052] The two detergent box cavities 21 are spaced apart, with an overflow channel 29 located between them to facilitate overflow of the detergent powder chamber 211. A second guide groove 34 is provided on the mounting plate 30 to mate with the upper edge 216. The upper edge 216 is positioned within the second guide groove 34, allowing for forward and backward movement. Positioning the upper edge 216 within the second guide groove 34 enhances stability during the draw-out of the detergent box 20, preventing side-to-side shaking. It also further isolates the adjacent detergent box cavities 21, preventing the intrusion of wash water.

[0053] The limiting structure includes a first limiting protrusion 221 extending upward from the first folded edge 22 and a second limiting protrusion 35 extending downward from the mounting plate 30. The first limiting protrusion 221 and the second limiting protrusion 35 are matched to each other and are used to limit the closure of the detergent box 20. The limiting structure includes a limiting plate 36 extending downward from the mounting plate 30. The limiting plate 36 cooperates with the rear wall of the detergent box 20 to limit the opening of the detergent box 20. When the detergent box 20 is fully closed, the second limiting protrusion 35 blocks the first limiting protrusion 221, preventing the detergent box 20 from moving further backward. When the detergent box 20 is fully opened, the limiting plate 36 is positioned in front of the rear wall of the detergent box 20, preventing the detergent box 20 from moving further forward.

[0054] See also Figure 3-Figure 5 As shown, the water box 10 is provided with a water inlet 13 that communicates with the water inlet pipe of the washing machine, and the detergent box 20 is provided with a water diversion pipe 25 extending toward the water inlet 13. The water diversion pipe 25 is used to divert a portion of the water flowing through the water inlet 13 into the detergent holding chamber 21 for diluting and dissolving the detergent in the detergent holding chamber 21. Of the water flowing through the water inlet 13, a portion is diverted into the detergent holding chamber 21, and the other portion flows directly into the water box 10; that is, a portion of the water is diverted into the detergent holding chamber 21 to dilute and dissolve the detergent in the detergent holding chamber 21, and then flows out of the detergent holding chamber 21 into the water box 10 and flows to the bottom wall of the water box 10; the other portion flows directly to the bottom wall of the water box 10. The incoming water flow does not pass through the water inlet chamber. Part of it flows into the detergent holding chamber 21, and the other part flows directly into the water box 10. This shortens the path of the water flow in the water inlet box assembly 100, which is beneficial to improving water inlet efficiency. At the same time, it can save the installation of a water diverter plate or a water inlet chamber, simplify the structure of the water inlet box assembly 100, and is beneficial to improving the manufacturing efficiency and reducing the manufacturing cost of the water inlet box assembly 100. In addition, by diverting the incoming water flow, the other part flows directly into the water box 10 without passing through the detergent box 20, so that the path of this part of the water flow is further shortened, thereby improving water inlet efficiency. It also prevents all the incoming water from flowing through the detergent holding chamber 21, avoiding overflow when the detergent holding chamber 21 uses siphon water inlet and preventing the clothes from being rinsed uncleanly.

[0055] For ease of description, the water flow path that flows through the water inlet 13, then into the detergent holding chamber 21, and then into the water box 10 is defined as the first flow path, and the water flow path that flows through the water inlet 13 and directly into the water box 10 is defined as the second flow path. The detergent box 20 is provided with multiple detergent holding chambers 21, and correspondingly, multiple water diversion pipes 25 extending toward the water inlet 13 are provided.

[0056] To ensure that a portion of the water flowing through the water inlet 13 flows into the water diversion pipe 25, the direction of the water outflow from the water inlet 13 must be aligned with the axis of the water diversion pipe 25. This ensures that a portion of the water ejected from the water inlet 13 impacts the water diversion pipe 25 and, in turn, reaches the detergent holding chamber 21. The water inlet 13 extends in a front-to-back direction, and the water diversion pipe 25 also extends in a front-to-back direction. Specifically, in this embodiment, the water inlet 13 has a water inlet 131 disposed on the rear wall of the water box 10. The axis of the water inlet 131 is parallel to or coincides with the axis of the water diversion pipe 25. The rearward projection of the water diversion pipe 25 is located within the water inlet 13.

[0057] To achieve diversion of the water flow through the water inlet 13, various implementations are possible. In the first implementation, when the detergent box 20 is closed, the water inlet 13 and the water diversion pipe 25 are spaced apart, or in other words, are not sealed. A certain distance exists between the outlet of the water inlet 13 and the inlet of the water diversion pipe 25 in the front-to-back direction. Part of the water flowing forward from the outlet of the water inlet 13 flows into the water diversion pipe 25, while the remaining water flows forward from the outlet of the water inlet 13 and falls into the water box 10, flowing onto the bottom wall of the water box 10. The second implementation is that when the detergent box 20 is closed, the water inlet 13 and the water diversion pipe 25 are spaced apart, with the outlet of the water inlet 13 sheathed outside the inlet of the water diversion pipe 25. A certain radial distance exists between the outlet of the water inlet 13 and the inlet of the water diversion pipe 25. Part of the water rushing forward from the water inlet 13 flows into the water diversion pipe 25, while the remaining part continues forward, exits through the outlet of the water inlet 13, falls into the water tray 10, and flows onto the bottom wall of the water tray 10. A third solution is to provide a wall opening 134 in the wall of the water inlet 13. Water flowing through this opening 134 flows directly into the water tray 10. When the detergent box 20 is closed, the water diversion pipe 25 extends into the water inlet 13. Part of the water rushing forward from the water inlet 13 flows into the water diversion pipe 25. This embodiment uses the third solution as an example for detailed description.

[0058] The amount of water diverted through the first flow path is smaller than that of the second flow path. A larger amount of water flows through the shorter second flow path, further improving water inlet efficiency. The inner diameter of the water diversion pipe 25 is smaller than the diameter of the water inlet 131. The inner diameter of the water diversion pipe 25 is the diameter of the inner cavity of the water diversion pipe 25. The ratio of the diameter of the water diversion pipe 25 to the diameter of the water inlet 131 is 0.2 to 0.4.

[0059] See also Figure 4 、 Figure 5 and Figure 11 25, which illustrates the structure of the water inlet portion 13 and the water diversion pipe 25. The water inlet portion 13 comprises a water inlet 131 provided on the rear wall of the water box 10, an outer water inlet pipe 132 extending outwardly from the water inlet 131, and an inner water inlet pipe 133 extending inwardly from the water inlet 131. Specifically, the outer water inlet pipe 132 extends rearwardly from the water inlet 131, while the inner water inlet pipe 133 extends forwardly from the water inlet 131.

[0060] A wall opening 134 is provided on the wall of the inner water inlet pipe 133 to divert the remaining portion of water flowing through the water inlet portion 13 into the water box. This opening 134 is positioned adjacent to the water inlet 131, that is, adjacent to the inner side of the rear wall of the water box 10. This allows water flowing out of the opening 134 to flow along the rear wall of the water box 10, facilitating the shortest possible flow path. Preferably, the opening 134 is positioned below the inner water inlet pipe 133, allowing the water to flow directly downward. Two drainage ribs 16 are provided on the rear wall of the water box 10, connected to the opening 134, to guide the outflowing water. The two drainage ribs 16 are positioned downwardly away from each other.

[0061] When the detergent box 20 is closed, the water diversion pipe 25 is located within the inner water inlet pipe 133, which helps maintain the water pressure after the water enters the water diversion pipe 25. The rear end of the water diversion pipe 25 is located above the pipe wall opening 134. The water flowing through the water inlet 131 is divided into two paths: one part flows forward into the detergent holding chamber 21, forming the first flow path; the other part flows downward through the pipe wall opening 134 and enters the water box 10, forming the second flow path.

[0062] The detergent box 20 can be pulled out and drawn in the front-to-back direction. When the detergent box 20 moves, it drives the water guide pipe 25 to move with it. The water inlet portion 13 is arranged in the front-to-back direction. When the detergent box 20 is closed, the water guide pipe 25 is inserted into the inner water inlet pipe 133. In the closed state, the water flow ejected forward from the front end of the inner water inlet pipe 133 flows into the water guide pipe 25 or is blocked by the detergent box 20 and then flows to the bottom wall of the water box 10; however, when the detergent box 20 is open, if water is accidentally inletted, part of the water flow ejected forward from the front end of the inner water inlet pipe 133 will flow out from the front of the water box 10. To prevent water from flowing out of the front end of the water box 10, a water baffle 37 is provided on the mounting plate 30 in front of the water inlet 13 to prevent water from spraying forward. A through hole 371 for the water diversion pipe 25 to extend is provided on the water baffle 37, and a one-way valve 373 is provided on the water baffle 37 to prevent water from spraying forward from the through hole 371. The water diversion pipe 25 can extend into the through hole 373, and the water diversion pipe 25 can move backward to open the one-way valve 373. The one-way valve 373 cannot be opened forward, but can be opened backward. When the detergent box 20 is in the open state, the water inlet pipe 25 is disengaged from the through hole 373, and the one-way valve 373 is in the closed state. When the water flowing out of the water inlet 13 hits the one-way valve 373 upward, the one-way valve 373 is subjected to a forward force, and the forward-impacting water flow is blocked by the one-way valve 373 and the water baffle 37. The water flows downward along the water baffle 37, preventing the water from flowing out from the front end of the water box 10.

[0063] See also Figure 13 As shown, the water baffle 37 is provided with a rear extension pipe 372 extending backward along the edge of the through hole 373. The rear extension pipe 372 extends into the inner water inlet pipe 133, and the water diversion pipe 25 is located within the rear extension pipe 372. The mounting plate 30 is installed so that the first guide groove 15 and the first guide groove 31 cooperate. When the mounting plate 30 is moved backward, the rear extension pipe 372 is pushed into the inner water inlet pipe 133. The push-type check valve 373 is set at the rear end of the rear extension pipe 372. The provision of the rear extension pipe 372 facilitates filling the gap between the water diversion pipe 25 and the rear extension pipe 372, preventing a large amount of water from flowing from the water diversion pipe 25 and the rear extension pipe 372 into the water box 10. It also helps to increase the contact area between the water diversion pipe 25 and the water baffle 37, thereby strengthening the support for the water diversion pipe 25.

[0064] The water inlet 13 is arranged on the rear wall of the water box 10, and can be connected to the water inlet valve 40, which saves the hose between the water inlet 13 and the water inlet valve 40, is conducive to reducing the structure and improving assembly efficiency.
