[0035] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be particularly noted that the following embodiments are for illustrative purposes only and do not limit the scope of the application. Similarly, the following embodiments are only some, not all, embodiments of the present application, and all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present application.

[0036] The terms "comprising" and "having," and any variations thereof, used in the embodiments of this application, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or components inherent to such processes, methods, products, or devices.

[0037] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0038] Please see Figures 1 to 3 , Figure 1 This is a schematic diagram of the distribution mechanism from one perspective in some embodiments of this application. Figure 2 yes Figure 1 A schematic cross-sectional view of the dispensing mechanism at point AA in the embodiment when it is in a vertical position. Figure 3 yes Figure 1 A schematic cross-sectional view of point AA when the dispensing mechanism is in a horizontal state in the embodiment.

[0039] This application provides a dispensing mechanism suitable for washing equipment such as dishwashers, and configured to be installed on the wall of a corresponding washing tub. For example, in a dishwasher, the dishwasher door is pivotally connected to the machine body via a horizontal pivot to open and close the inner cavity. The wall of the washing tub may be defined by a structure disposed on the inner side of the door; the dispensing mechanism is fixed to this inner side of the door. During door rotation, the dispensing mechanism undergoes a posture change, allowing it to have a vertical state and a horizontal state. The dispensing mechanism includes a main body 10 and a cover 20.

[0040] Please refer to the combination Figure 2 and Figure 3 The main body 10 can be made of metal, alloy, or plastic. The main body 10 has a receiving groove 12 for holding detergent. When the main body 10 is installed on the door of the dishwasher, the receiving groove 12 is located on the side of the main body 10 facing away from the inner side of the door. When the door is opened, the dispensing mechanism rotates with the door to a horizontal position, and the opening of the dispensing receiving groove 12 faces upwards to facilitate the loading of detergent into the receiving groove 12. When the door is closed, the dispensing mechanism rotates with the door to a vertical position, and the opening of the receiving groove 12 faces horizontally, allowing the detergent in the receiving groove 12 to slide down into the washing area inside the cavity under gravity. The detergent can be solid, powdered, or liquid; this embodiment does not specifically limit the type of detergent.

[0041] Please participate in the reading. Figure 4 , Figure 4 yes Figure 2 The enlarged schematic diagram at point B in the embodiment shows that the main body 10 is also provided with a sealing part 13. The sealing part 13 is continuously arranged circumferentially along the opening of the receiving groove 12, and a flow guiding structure 14 is provided inside the sealing part 13.

[0042] The cover 20 has a first position and a second position relative to the main body 10. When the cover 20 is in the first position, it covers the opening of the receiving groove 12 and abuts against the sealing part 13. When the cover 20 is in the second position, at least part of the opening of the receiving groove 12 is exposed outside the cover 20. This allows the detergent in the receiving groove 12 to fall into the washing area in the inner cavity, thus realizing the dispensing of detergent. When the cover 20 is in the second position, a gap is formed between the cover 20 and the sealing part 13 for water to flow through. The flow guiding structure 14 is configured to guide water flow into the receiving groove 12 and guide the detergent in the receiving groove 12 to the outside of the receiving groove 12 when water flows through the gap. The cover 20 can be switched in position by a hinge or a slide rail, and the gap width can be set according to the water flow requirements. When the cover 20 is in the second position, the detergent is impacted by the water flow and can flow directionally along the flow guiding structure 14 to avoid residue.

[0043] In this embodiment, when the cover 20 is in the second position, the water flow is guided by the guide structure 14 as it passes through the gap, forming a directional impact. The water flow dynamics flush the detergent residue adhering to the inner wall of the receiving tank 12 to the outside, effectively solving the problem of detergent residue residue in traditional structures. This design not only improves the utilization efficiency of detergent residue but also reduces the interference of residue inside the equipment on subsequent washing processes. Simultaneously, the cooperation between the sealing part 13 and the cover 20 achieves good sealing performance and functional switching between open and closed states.

[0044] The terms "first," "second," and "third" used in the embodiments of this application are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first," "second," and "third" may explicitly or implicitly include at least one of those features.

[0045] In some embodiments, a first surface 1511 is formed on the body 10, the first surface 1511 being located on the side of the body 10 facing away from the dishwasher door. The cover 20 is designed to be linearly movable on the first surface 1511, thereby switching between a first position and a second position.

[0046] Please see Figure 5 and Figure 6 , Figure 5 yes Figure 1 A schematic diagram of the main structure of the distribution mechanism in the embodiment. Figure 6 yes Figure 1 A schematic diagram of the cover of the dispensing mechanism in the embodiment.

[0047] In some embodiments, the main body 10 is provided with a release mechanism 40 and a holding mechanism 30. The holding mechanism 30 is used to hold the cover 20 in a first position, and the release mechanism 40 is used to drive the cover 20 out of the first position and switch to a second position. Specifically, the holding mechanism 30 includes a snap-fit ​​part 31 and a snap-fit ​​engagement part 32 that cooperates with the snap-fit ​​part 31. The snap-fit ​​part 31 is provided on the cover 20, and the snap-fit ​​engagement part 32 is provided on the main body 10. When the cover 20 is in the first position, the snap-fit ​​part 31 engages with the snap-fit ​​engagement part 32, thereby holding the cover 20 in the first position, that is, holding the cover 20 in a state that covers the opening of the receiving groove 12.

[0048] Please combine Figure 5 and Figure 6 The release mechanism 40 can act on the engaging part 32 to disengage it from the engaging part 31. Specifically, the engaging part 32 has a third position and a fourth position relative to the main body 10. In the third position, the engaging part 32 engages with the engaging part 31, and in the fourth position, it disengages from the engaging part 31. A first elastic element (not shown) is provided between the engaging part 32 and the main body 10. The first elastic element acts on the engaging part 32 to ensure that the engaging part 31 always tends to move towards the third position. The first elastic element includes, but is not limited to, elastic bodies such as springs, torsion springs, etc. The release mechanism 40 can drive the engaging part 32 to move from the third position to the fourth position. The release mechanism 40 supports both automatic and manual control modes. For example, as... Figure 1 As shown, the release mechanism 40 includes a button 41, which is elastically connected to the cover 20. The button 41 is partially exposed on the surface of the cover 20 to facilitate user operation. By operating the button 41, the button 41 presses against the locking engagement part 32, causing it to move from the third position to the fourth position.

[0049] In addition, such as Figure 5 As shown, the release mechanism 40 can also drive the cover 20 from the first position to the second position. The release mechanism 40 includes a second elastic element 42, which is connected between the main body 10 and the cover 20. The second elastic element 42 acts on the cover 20 so that the cover 20 always has a tendency to move towards the second position. The second elastic element 42 includes, but is not limited to, springs, torsion springs, and sheet springs.

[0050] In this embodiment, by setting a retaining mechanism 30 and a releasing mechanism 40, the retaining mechanism 30 continuously applies an elastic force toward the third position to the engaging part 32 through the first elastic member, ensuring that the engaging part 31 always has the tendency to engage with the main body 10, thereby achieving stable fixation of the cover 20 in the first position; the releasing mechanism 40 can hold the engaging part 32 against the elastic force of the first elastic member, causing it to move from the third position to the fourth position. At this time, the engagement restriction is released, and the second elastic member 42 connected between the main body 10 and the cover 20 always has the tendency to push the cover 20 to the second position, and its elastic potential energy is rapidly released, causing the cover 20 to automatically bounce up from the first position to the second position, completing the convenient opening of the cover 20.

[0051] Please see Figure 4 and Figure 5 In some embodiments, the sealing portion 13 includes a water inlet section 131, which forms a gap with the cover 20 when the cover 20 is in the second position. The flow guiding structure 14 includes a first flow guiding surface 141, at least a portion of which is defined by the side of the water inlet section 131 facing the receiving groove 12. The first flow guiding surface 141 is inclined along the depth direction of the receiving groove 12, and the first flow guiding surface 141 gradually converges towards the center of the receiving groove 12 from one end near the cover 20 to the other end away from the cover 20.

[0052] It should be noted that when the dispensing mechanism is in a vertical position, the inlet section 131 is located at the top of the sealing part 13, and the water flows from top to bottom through the dispensing mechanism. The first guide surface 141 is located on the side of the inlet section 131 facing the receiving groove 12, that is, the first guide surface 141 is located on the top wall of the receiving groove 12. When the water flows from top to bottom through the gap between the cover 20 and the inlet section 131, the water will contact the edge of the inlet section 131 and then flow into the interior of the receiving groove 12 along the inclined first guide surface 141. The surface of the first guide surface 141 can be provided with micron-level texture to enhance the liquid flow guidance.

[0053] By setting a gap between the water inlet section 131 and the cover 20 to form a liquid channel, and with the directional guidance of the first guide surface 141, the water flows through the gap and the first guide surface 141 into the receiving tank 12, flushing the tank wall of the receiving tank 12, achieving a self-cleaning effect, so that the washing material can quickly and completely enter the washing area after the cover 20 is opened, improving the distribution efficiency and reducing the residue rate.

[0054] Please see Figure 5In some embodiments, the receiving tank 12 has a bottom wall 121 and a second guide surface 122, the second guide surface 122 being located on the side of the receiving tank 12 away from the water inlet section 131. The second guide surface 122 is part of the guide structure 14, and the bottom wall 121 and the second guide surface 122 form an angle, the angle being less than or equal to 145° and greater than or equal to 100°.

[0055] In specific implementations, the included angle between the bottom wall 121 and the second guide surface 122 can be 100°, 110°, 120°, 130°, 140°, or 145°, or a gradually transitioning curved surface structure can be used instead of a right-angle bend. This application does not impose specific limitations on the embodiments. The inclination angle between the bottom wall 121 and the second guide surface 122 allows the detergent to slide more easily to the outside of the distribution chamber under gravity, while reducing the accumulation of detergent material at the edge of the tank.

[0056] By setting the angle between the bottom wall 121 and the second guide surface 122 within a specific range, the flow characteristics of the detergent in the receiving tank 12 can be effectively improved. When the cover 20 is opened, the inclined structure can guide residual gel blocks or powder to slide down the inclined surface, reducing the probability of residue.

[0057] Please continue reading. Figure 5 In some embodiments, the flow guiding structure 14 includes a plurality of flow guiding ribs 142 disposed on the second flow guiding surface 122. The flow guiding ribs 142 on the second flow guiding surface 122 are spaced apart and extend along the end of the second flow guiding surface 122 near the bottom wall 121 toward the opening direction of the receiving groove 12.

[0058] In some embodiments, the flow guiding structure 14 includes a plurality of flow guiding ribs 142 disposed on the bottom wall 121. The flow guiding ribs 142 on the bottom wall 121 are spaced apart and extend toward the second flow guiding surface 122 from one end of the bottom wall 121 away from the second flow guiding surface 122.

[0059] In some embodiments, the flow guiding structure 14 includes a plurality of flow guiding ribs 142 disposed on the first flow guiding surface 141. The flow guiding ribs 142 on the first flow guiding surface 141 are spaced apart and extend along the end of the first flow guiding surface 141 near the bottom wall 121 toward the opening direction of the receiving groove 12.

[0060] In practical implementation, the cross-sectional shape of the guide ribs 142 can be triangular, semi-circular, or trapezoidal, and its extension direction matches the flow path of the detergent. After the cover 20 is opened, the guide ribs 142 can also form a local flow guide during the detergent dispensing process, preventing detergent from accumulating in the receiving tank 12. The guide ribs 142 at different positions cooperate with each other to change the direction of water flow, guiding the water flow evenly to various parts in the receiving tank 12, and promoting smoother movement of the detergent towards the opening of the receiving tank 12. Residual detergent will slide down the surface of the guide ribs 142 into the washing area of ​​the inner cavity under the rinsing of the water flow, reducing the amount of residue.

[0061] By incorporating directional guide ribs 142 at multiple locations, the amount of detergent residue in the container 12 can be effectively reduced, ensuring that the detergent is completely released into the dishwasher after the lid 20 is opened. The guide ribs 142 alter the flow path of the detergent, reducing its likelihood of adhering to the walls of the container 12, thereby improving the utilization rate of the detergent.

[0062] In some embodiments, the sealing part 13 has a protruding annular rectangular structure, and the cover 20 has a sealing mating part 21. The sealing mating part 21 is annular and corresponds to the sealing part 13. When the cover 20 is in the first position, the sealing mating part 21 abuts against the sealing part 13.

[0063] When the cover 20 is in the first position, the sealing part 13 and the sealing mating part 21 form a contact seal. The protruding sealing part 13 structure can compensate for assembly tolerances and maintain sealing pressure. The sealing part 13 can be made of rubber or silicone material, or the sealing mating part 21 of the cover 20 can be designed with a structure that has elastic deformation capability. Alternatively, the annular rectangle can be replaced with other continuous closed shapes, such as circles or ellipses, as long as the continuity of the sealing contact surface is maintained.

[0064] When the cover 20 is in the first position, the continuous annular sealing structure effectively blocks moisture from entering through the gap between the cover 20 and the main body 10 of the dispensing mechanism, preventing the washing material from becoming ineffective due to moisture or contamination. At the same time, the continuous and uniform sealing contact surface can avoid deformation or damage to the sealing part 13 caused by excessive local pressure, extending the service life of the sealing structure.

[0065] Please see Figure 5 and Figure 6 In some embodiments, the cover 20 and the main body 10 are provided with a guide structure, which includes a guide groove 51 and a guide post 52. The guide groove 51 is provided in one of the cover 20 and the main body 10, and the guide post 52 is provided in the other of the cover 20 and the main body 10. The guide post 52 is inserted into the guide groove 51 and slides along the guide groove 51 and rotates in the guide groove 51.

[0066] After the guide post 52 is inserted into the guide groove 51, it can move along the length of the groove and rotate around its own axis during the movement. The guide groove 51 can be configured as a recessed structure, and the guide post 52 as a columnar protrusion, or the guide groove 51 can be designed as a channel penetrating the groove. Through the cooperation of the guide groove 51 and the guide post 52, it is possible to ensure that the cover 20 maintains a stable movement trajectory during opening and closing, avoiding poor sealing problems caused by misalignment.

[0067] It should be noted that the rotational characteristics of the guide post 52 allow the cover 20 to achieve a tighter sealing contact through adaptive rotation when closed, thereby improving the sealing effect. This structural design also allows a gap to be created between the cover 20 and the main body 10 when the cover 20 is open, through the rotation of the cover 20, so that water can flow into the receiving groove 12 through the gap.

[0068] Please see Figure 5 and Figure 6 In one specific embodiment, the guide groove 51 includes a first guide groove 511 and a second guide groove 512 disposed on the main body 10. The first guide groove 511 and the second guide groove 512 are not parallel. The guide post 52 includes a first guide post 521 and a second guide post 522 disposed at intervals on the cover 20. The first guide post 521 is inserted into the first guide groove 511, and the second guide post 522 is inserted into the second guide groove 512.

[0069] When the dispensing mechanism is in a vertical position, the general orientation of the first guide groove 511 and the second guide groove 512 is consistent with the direction from the bottom to the top of the dispensing mechanism, that is, with... Figure 5 The Y-direction is consistent throughout. The first guide post 521 and the second guide post 522 are both vertically fixed to the side wall of the cover 20, and the axes of both are parallel to the sealing mating part 21 of the cover 20. Since the first guide groove 511 and the second guide groove 512 are not parallel, the first guide post 521 and the second guide post 522 in the cover 20 can rotate simultaneously when sliding along the guide groove 51. It can be understood that the first guide post 521 forms a high-pair fit with the first guide groove 511, and the second guide post 522 forms a high-pair fit with itself; that is, two high-pair fits are formed between the cover 20 and the main body 10. Thus, the movement trajectory of the cover 20 relative to the main body 10 is unique, allowing the cover 20 to move relative to the main body 10 between a first position and a second position according to a predetermined trajectory.

[0070] Please see Figure 5Furthermore, the first guide groove 511 includes a first end 5111 and a second end 5112 disposed opposite to each other, and the second guide groove 512 includes a third end 5121 and a fourth end 5122 disposed opposite to each other. The distance between the first end 5111 and the third end 5121 in the depth direction of the receiving groove 12 is less than the distance between the second end 5112 and the fourth end 5122 in the depth direction of the receiving groove 12. The depth direction of the receiving groove 12 is... Figure 5 The Z-direction is consistent. When the cover 20 is in the first position, the first guide post 521 is located at the first end 5111, and the second guide post 522 is located at the third end 5121; when the cover 20 is in the second position, the first guide post 521 is located at the second end 5112, and the second guide post 522 is located at the fourth end 5122.

[0071] By utilizing the difference in the distance between the endpoints of the first guide groove 511 and the second guide groove 512, the cover 20 is tilted at a specific angle when it is opened via a guideable structure. It can be understood that because the distance between the first end 5111 and the third end 5121 in the depth direction (Z direction) of the receiving groove 12 is less than the distance between the second end 5112 and the fourth end 5122 in the depth direction (Z direction) of the receiving groove 12, the angle of tilt of the cover 20 relative to the receiving groove 12 when it is in the first position is less than the angle of tilt of the cover 20 relative to the receiving groove 12 when it is in the second position. Specifically, when the cover 20 is in the first position, the end parallel to the first sealing part 13 facing the cover 20 facilitates a tight fit between the cover 20 and the first sealing part 13, achieving a seal on the receiving groove 12. When the cover 20 moves to the second position, at least part of the opening of the receiving groove 12 is exposed outside the cover 20, and the cover 20 rotates relative to the receiving groove 12 to form a gap between the cover 20 and the first sealing part 13, so that water can enter the receiving groove 12 through the gap and thus flush the inner wall of the receiving groove 12.

[0072] In one specific embodiment, when the cover 20 is closed, i.e., when the cover 20 moves from the second position to the first position, the first guide post 521 and the second guide post 522 slide downwards along the trajectory of the first guide groove 511. Since the first guide groove 511 and the second guide groove 512 are not parallel, the movement of the first guide post 521 and the second guide post 522 generates a clockwise torque on the cover 20, causing the cover 20 to rotate around the axis of the first guide post 521 toward the main body 10 by a certain angle until the sealing mating part 21 of the cover 20 is completely fitted with the sealing part 13 of the main body 10. At this time, the rotational characteristics of the cover 20 make the pressure between the sealing surfaces uniform.

[0073] When the cover 20 is opened, that is, when the cover 20 moves from the first position to the second position, the first guide post 521 and the second guide post 522 slide upward along the first guide groove 511. The movement of the first guide post 521 and the second guide post 522 generates a counterclockwise torque on the cover 20, causing the cover 20 to rotate around the axis of the first guide post 521 away from the main body 10 by a certain angle, thereby forming an inclined gap between the cover 20 and the main body 10. Water can flow smoothly into the receiving groove 12 below along this gap. This embodiment achieves the stability of the opening and closing of the cover 20 through a combination of motion (translation + rotation), while also taking into account the reliability of the seal and the smoothness of water inflow.

[0074] like Figure 5 As shown, in some embodiments, the first guide groove 511 includes a bent end 5113 disposed between the first end 5111 and the second end 5112. The distance between the bent end 5113 and the bottom wall 121 of the receiving groove 12 is greater than the distance between the first end 5111 and the bottom wall 121 of the receiving groove 12 and the distance between the second end 5112 and the bottom wall 121 of the receiving groove 12. The portion of the first guide groove 511 between the first end 5111 and the bent end 5113 is smoothly connected to the portion of the first guide groove 511 between the second end 5112 and the bent end 5113.

[0075] When the cover 20 is in the first and second positions, the structural design of the bent end 5113 plays a crucial role in the stable locking of the cover 20. Because the distance from the bent end 5113 to the bottom wall 121 of the receiving groove 12 is greater than the distance from the first end 5111 to the bottom wall 121 of the receiving groove 12, when the first guide post 521 is located at the first end 5111, the bent end 5113 forms a "structural step" higher than the first end 5111. This makes it difficult for the first guide post 521 to slide towards the second end 5112 by itself, overcoming the height difference of the bent end 5113 under external vibration or slight external force, thus providing a mechanical limiting effect for the cover 20. Similarly, when the first guide post 521 is located at the second end 5112, the bent end 5113 forms a "structural step" higher than the second end 5112, making it difficult for the first guide post 521 to slide towards the first end 5111 by itself, overcoming the height difference of the bent end 5113, under external vibration or slight external force.

[0076] Please continue reading. Figure 5 and Figure 6In some embodiments, the first sidewall 5114 of the first guide groove 511 is provided with a first connecting groove 5115, which penetrates the first sidewall 5114 and the side of the main body 10 opposite to the first sidewall 5114; the second sidewall 5123 of the second guide groove 512 is provided with a second connecting groove 5124 parallel to the first connecting groove 5115, which penetrates the second sidewall 5123 and the side of the main body 10 opposite to the second sidewall 5123; the distance between the first connecting groove 5115 and the second connecting groove 5124 is equal to the distance between the first guide post 521 and the second guide post 522.

[0077] The through-type connecting groove design also facilitates the quick insertion of the guide post 52 during assembly. Since the spacing between the first connecting groove 5115 and the second connecting groove 5124 matches the spacing between the first guide post 521 and the second guide post 522, the second guide post 522 can be inserted into the second connecting groove 5124 at the same time as the first guide post 521 is inserted into the first connecting groove 5115. Thus, the first guide post 521 is assembled into the first guide groove 511 through the first connecting groove 5115, and the second guide post 522 is assembled into the second guide groove 512 through the second connecting groove 5124, improving assembly efficiency.
