Description

Technical Field

[0001] This application belongs to the field of washing device technology, and particularly relates to a detergent dispensing component and a washing machine. Background Technology

[0002] Washing machines typically have a detergent dispenser. This dispenser prevents high-concentration detergent from directly contacting clothes, which could damage the dye and even the fabric structure. As people's living standards improve, the dyes on clothes are becoming more natural, and the fabrics are becoming more delicate, requiring careful handling. Therefore, detergent dispensers are being used more frequently. However, traditional detergent dispensers often slide directly against the inner wall of the water tank, creating significant friction and making it difficult to push or pull the dispenser in or out of the tank, thus making it inconvenient to use. Summary of the Invention

[0003] This application provides a detergent dispensing component and a washing machine to solve the problem of inconvenience in using existing detergent dispensing components.

[0004] In a first aspect, embodiments of this application provide a detergent dispensing assembly, comprising:

[0005] A water box, comprising an upper shell, a lower shell, a rolling element, and a connecting element, wherein the upper shell and the lower shell form a receiving cavity, the rolling element is disposed within the receiving cavity, and the rolling element is connected to the upper shell through the connecting element and is spaced apart from the upper shell to form an installation space;

[0006] A detergent dispenser is movable relative to the water dispenser to enter and exit the receiving cavity; a mounting rail is provided on the side of the detergent dispenser facing the rolling element; the mounting rail is installed in the installation space and is rotatably connected to the rolling element.

[0007] In some embodiments, there are two hanging rails, which are respectively disposed on both sides of the detergent box in the width direction; there are two sets of rolling elements, which are respectively disposed on both sides of the upper shell in the width direction and are respectively tactilely connected to the two hanging rails; each set of rolling elements is provided with a plurality of rolling elements, and the plurality of rolling elements in each set of rolling elements are spaced apart in the extension direction of the hanging rail.

[0008] In some embodiments, the mounting rail includes a support portion and a first mounting portion, the support portion being connected to the detergent dispenser, and the first mounting portion being connected to the side of the support portion opposite to the detergent dispenser; the rolling element includes a first rolling wheel, and the connecting element includes a first bracket, the first rolling wheel being rotatably connected to the first bracket and rotatably connected to the first mounting portion; the first bracket is disposed on the side of the first rolling wheel opposite to the detergent dispenser and is installed on the inner wall of the receiving cavity.

[0009] In some embodiments, the rolling element further includes a second rolling wheel, and the connecting element further includes a second bracket, the second rolling wheel being rotatably connected to the second bracket, the second bracket being disposed on the side of the second rolling wheel facing the detergent dispenser; the hook guide rail further includes a second hooking part, the second hooking part being disposed on the side of the supporting part facing the detergent dispenser; the second rolling wheel is rotatably connected to the second hooking part.

[0010] In some embodiments, the wall surface of the first hook portion that mates with the first rolling wheel is an arc surface, and the center of curvature faces the first rolling wheel; and / or

[0011] The wall surface of the second hook part that mates with the second rolling wheel is an arc surface, and the center of curvature faces the second rolling wheel.

[0012] In some embodiments, the connector is detachably connected to the upper housing.

[0013] In some embodiments, the detergent dispenser is further provided with a limiting rib, which extends along the extension direction of the hook guide; a limiting groove is provided on the inner wall of the receiving cavity; and the limiting rib is engaged in the limiting groove.

[0014] In some embodiments, the limiting rib and the inner wall of the limiting groove cooperate with each other in the width direction of the detergent box and in the arrangement direction of the upper shell and the lower shell.

[0015] In some embodiments, the mounting rail is disposed on the side of the detergent dispenser near the upper shell.

[0016] Secondly, embodiments of this application also provide a washing machine, the washing machine including a detergent dispensing assembly as described in any of the preceding claims.

[0017] The detergent dispensing assembly provided in this application embodiment has a detergent box that is attached to a rolling element via a hanging track. At the same time, the detergent box does not need to fit with the inner wall of the water box's receiving cavity, such as the side wall of the detergent box not needing to slide with the water box. This transforms the sliding friction resistance between the detergent box and the water box into rolling friction resistance, greatly reducing the friction force. This allows the detergent box to be easily pushed into or pulled out of the water box, making it more convenient for people to use the detergent dispensing assembly. Attached Figure Description

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0029] This application provides a detergent dispensing assembly and a washing machine to solve the problems of existing detergent dispensing assemblies. The following description is in conjunction with the accompanying drawings.

[0030] The detergent dispensing component provided in this application embodiment can be applied to washing machines, but it can also be applied to washing devices such as dishwashers. (Reference) Figure 1 The detergent dispensing assembly provided in this application includes a water tank and a detergent dispenser 30. The water tank includes an upper shell 10, a lower shell 20, a rolling element 40, and a connecting element 60. The upper shell 10 and the lower shell 20 form a receiving cavity. The rolling element 40 is disposed in the receiving cavity and is connected to the upper shell 10 via the connecting element 60, and is spaced apart from the upper shell 10 to form an installation space. The detergent dispenser 30 can move relative to the water tank to enter and exit the receiving cavity. A hanging guide rail 50 is provided on the side of the detergent dispenser 30 facing the rolling element 40. The hanging guide rail 50 is installed in the installation space and is rotatably connected to the rolling element 40.

[0031] Figure 1 To facilitate observation of the movement of the detergent dispenser 30 and the installation position of the rolling element 40, the upper shell 10 is removed. For a detailed description of the structure of the upper shell 10, please refer to [reference needed]. Figure 3 .exist Figure 3 In this embodiment, the upper shell 10 and the lower shell 20 are connected by a snap-fit ​​11. However, in other embodiments of this application, the upper shell 10 and the lower shell 20 may also be integrally formed, bonded with adhesive, or welded using a hot-melt method. (See reference...) Figure 1 , Figure 1 The detergent dispenser 30 is in a semi-open state, meaning that part of it protrudes outside the receiving cavity; however, the detergent dispenser 30 can also be moved along... Figure 1 Multiple rolling elements 40 move in the same direction to enter and exit the receiving cavity. During the movement of the detergent dispenser 30, the connecting rail 50 and the rolling wheels are in a rolling connection, resulting in low frictional resistance and making it easy for the detergent dispenser 30 to enter and exit the receiving cavity. It is worth noting that multiple rolling elements 40 do not necessarily need to be installed, because even if only one rolling component is installed, it can still reduce some frictional resistance through rolling connection with the connecting rail 50, making it convenient for the user.

[0032] In addition, the part responsible for rolling in the rolling element 40 is not necessarily a rolling wheel structure; it can also be a ball structure or a bearing structure.

[0033] refer to Figure 5In some embodiments, there are two mounting rails 50, which are respectively arranged on both sides of the detergent dispenser 30 in the width direction; further reference Figure 1 There are two sets of rolling elements 40. The two sets of rolling elements 40 are respectively arranged on both sides of the upper shell 10 in the width direction and are respectively tactilely connected to two hanging guide rails 50. Each set of rolling elements 40 is provided with multiple rolling elements 40, and the multiple rolling elements 40 in each set of rolling elements 40 are spaced apart in the extension direction of the hanging guide rail 50. Figure 5 The cross-sectional view, passing through the axis of the first rolling wheel 41 and perpendicular to the extending direction of the mounting guide rail 50, shows that the mounting guide rail 50 is positioned on both sides of the detergent dispenser 30 in the width direction, allowing for mounting between the detergent dispenser 30 and the rolling element 40 on both sides of the detergent dispenser 30; (Reference) Figure 1 Two sets of rolling elements 40 are respectively provided on both sides of the detergent box 30 in the width direction, and each set has multiple rolling elements 40 arranged at intervals in the extension direction of the hook guide rail 50. This allows the detergent box 30 to be supported by the rolling elements 40 at any position during the process of entering and exiting the receiving cavity. The above two features enable the detergent box 30 to be fully supported by the cooperation of the hook guide rail 50 and the rolling elements 40. In this way, the detergent box 30 can be moved without contacting the inner wall of the receiving cavity at any position except the hook guide rail 50. The detergent box 30 is only subject to frictional resistance when it moves, and the resistance is small, making it convenient for users to use.

[0034] refer to Figure 6 In some embodiments, the mounting rail 50 includes a support portion 51 and a first mounting portion 52. The support portion 51 is connected to the detergent dispenser 30, and the first mounting portion 52 is connected to the side of the support portion 51 opposite to the detergent dispenser 30. The rolling element 40 includes a first rolling wheel 41, and the connecting element 60 includes a first bracket 61. The first rolling wheel 41 is rotatably connected to the first bracket 61 and is tactilely connected to the first mounting portion 52. The first bracket 61 is disposed on the side of the first rolling wheel 41 opposite to the detergent dispenser 30 and is installed on the inner wall of the receiving cavity. Since the first mounting portion 52 is located on the side of the support portion 51 opposite to the detergent dispenser 30, the first mounting portion 52 can cooperate with the first rolling wheel 41 at a position as far away from the detergent dispenser 30 as possible in the width direction of the detergent dispenser 30. This makes the support of the mounting rail 50 for the detergent dispenser 30 more stable and prevents the detergent dispenser 30 from tipping over due to uneven distribution of the detergent liquid inside.

[0035] refer to Figure 6In some embodiments, the rolling element 40 further includes a second rolling wheel 42, and the connecting element 60 further includes a second bracket 62. The second rolling wheel 42 is rotatably connected to the second bracket 62, and the second bracket 62 is disposed on the side of the second rolling wheel 42 facing the detergent dispenser 30. The mounting rail 50 further includes a second mounting part 53, which is disposed on the side of the support part 51 facing the detergent dispenser 30. The second rolling wheel 42 is rotatably connected to the second mounting part 53. The first rolling wheel 41 and the second rolling wheel 42 support the mounting rail 50 on both sides. This increases the support strength and limits the movement of the mounting rail 50, preventing movement of the mounting rail 50 in the direction of the rotation axis of the second rolling wheel 42, thus making the movement of the detergent dispenser 30 more stable. (Reference) Figure 2 The first bracket 61 and the second bracket 62 can be connected as a single unit; or they can be separate units.

[0036] refer to Figure 6 In some embodiments, the wall surface of the first mounting portion 52 that mates with the first rolling wheel 41 is an arc surface, and the center of curvature faces the first rolling wheel 41; and / or

[0037] The wall surface of the second connecting part 53 that mates with the second rolling wheel 42 is an arc surface, and the center of curvature faces the second rolling wheel 42.

[0038] This allows the first rolling wheel 41 or the second rolling wheel 42 to simultaneously correct the movement direction of the hook guide 50 during rolling. When the movement direction of the hook guide 50 is not along the arrangement direction of the same set of rolling elements 40, the first rolling wheel 41 or the second rolling wheel 42 can use a torsional force through the arc-shaped first hook part 52 or the second hook part 53 to force the movement direction of the hook guide 50 back to the arrangement direction of the set of rolling elements. This further stabilizes the movement of the detergent dispenser 30.

[0039] refer to Figure 6 In some embodiments, the connector 60 is detachably connected to the upper housing 10. Figure 6 In the middle section, the upper shell 10 is provided with a snap-fit ​​11, which engages with the snap-fit ​​hole on the first bracket 61 to achieve a snap-fit ​​connection. This is one type of detachable connection. Similarly, a threaded connection can also be used, for example, a threaded hole is provided in the upper shell 10, and a screw is provided on the first bracket 61. The screw and the threaded hole engage to achieve a detachable connection. The detachable connection between the second bracket 62 and the receiving cavity can be the same as that of the first bracket 61. The detachable connection facilitates the disassembly and replacement of the rolling element 40, making later maintenance convenient.

[0040] refer to Figure 3 In some embodiments, the detergent dispenser 30 is further provided with a limiting rib 31, which extends along the extending direction of the hook guide rail 50; further refer to Figure 4 A limiting groove 21 is provided on the inner wall of the receiving cavity; a limiting rib 31 is engaged in the limiting groove 21. The limiting rib 31 is engaged within the limiting groove 21, thus restricting the movement direction of the limiting rib 31, even if the limiting rib 31 moves along its extension direction. This restricts the movement direction of the detergent dispenser 30, ensuring the stability of its movement even if the detergent dispenser 30 moves along the extension direction of the limiting rib 31.

[0041] refer to Figure 6 In some embodiments, the limiting rib 31 and the inner wall of the limiting groove 21 cooperate with each other in the width direction of the detergent box 30 and in the arrangement direction of the upper shell 10 and the lower shell 20. Figure 6 In the middle, it can be seen that the limiting rib 31 is in Figure 6 In the cross-section shown, a protrusion is present at the end away from the detergent dispenser 30. This protrusion extends in the arrangement direction of the upper shell 10 and the lower shell 20. Thus, when the detergent dispenser 30 tends to move away from or towards the inner wall of the receiving cavity, this protrusion, in conjunction with the inner wall of the limiting groove 21, can prevent this movement. Specifically, the limiting rib 31 and the inner wall of the limiting groove 21 engage in the width direction of the detergent dispenser 30 to limit its movement offset in that direction. Figure 6 As can also be seen, when the detergent dispenser 30 moves in the direction of the upper shell 10 and the lower shell 20, the limiting rib 31 can also cooperate with the inner wall of the limiting groove 21 to restrict the movement of the detergent dispenser 30 in that direction. Therefore, this arrangement can restrict the movement of the detergent dispenser 30 in two orthogonal directions, ensuring that the detergent dispenser 30 can only move in the direction of entering or exiting the receiving cavity. This guarantees the stability of the movement of the detergent dispenser 30. Furthermore, the aforementioned protrusion is not necessarily... Figure 6 The rectangle shown in the middle can also be other shapes, such as a circle, as long as the diameter of the circle is greater than the width of the other parts of the limiting rib 31 in the direction of arrangement of the upper shell 10 and the lower shell 20; or a trapezoid or an ellipse, etc.

[0042] refer to Figure 1 or Figure 3 In some embodiments, the mounting rail 50 is located on the side of the detergent dispenser 30 closest to the upper housing 10. This side of the detergent dispenser 30 is less likely to come into contact with detergent, preventing the mounting rail 50 and the rolling element 40 from becoming contaminated with detergent and increasing resistance. Therefore, smooth movement of the detergent dispenser 30 can be ensured.
