Description

Technical Field

[0001] This application relates to the field of dishwashers, and in particular to a dispensing mechanism. Background Technology

[0002] In modern life, dishwashers, as products in the field of automatic kitchen appliance cleaning, have gained market favor. However, the dispensers in existing dishwashers often produce excessive noise during detergent dispensing, leading to a poor user experience. Through research and experimentation, technicians have discovered that in the existing sealing sleeve reset structure, the solenoid valve periodically vibrates. The force exerted by the reset component on the reset mating part is not parallel to the axis between the reset component and the solenoid valve, generating a component force. This component force causes the reset component to vibrate, which, unlike the vibration of the solenoid valve, results in noise and reduces the customer experience. Utility Model Content

[0003] The technical problem to be solved by the embodiments of this application is to provide a dispensing mechanism that can stably and efficiently dispense detergent into a dishwasher with low noise, including:

[0004] A housing assembly having an accommodating cavity formed therein;

[0005] A sealing assembly, comprising a seal, a connector, and a reset assembly, wherein the sealing assembly is used to seal the accommodating cavity;

[0006] A drive assembly is provided, wherein the connector connects the seal and the drive assembly; the drive assembly drives the seal through the connector, thereby controlling the communication between different areas of the accommodating cavity;

[0007] The connector is provided with a reset mating component, and the reset component and the reset mating component form a contact engagement;

[0008] The seal, the connector, and the drive end of the drive assembly are coaxially arranged; when the drive assembly drives the connector to move to the drive end of the drive assembly, with the contact point between the reset assembly and the reset mating part as the vertex, the angle between the direction of the force of the reset assembly on the reset mating part and the plane containing the axes of the seal, the connector, and the drive assembly is C, where 0°≤C≤20°.

[0009] In some embodiments, the housing assembly includes a first housing and a second housing, the first housing and the second housing enclosing the receiving cavity;

[0010] The reset assembly includes a reset member and a first elastic member. The reset member and the first elastic member are disposed on the side of the second housing opposite to the accommodating cavity. One end of the reset member is rotatably disposed on the second housing, and the other end of the reset member abuts against the reset mating member. A first fixing member is disposed between the two ends of the reset member. One end of the first elastic member is connected to the second housing, and the other end of the first elastic member is connected to the first fixing member. The first elastic member drives the reset member to reset, thereby driving the sealing member to reset.

[0011] In some embodiments, the reset member includes a relief groove, a first abutment member, and a second abutment member, wherein the relief groove is disposed between the first abutment member and the second abutment member, and the relief groove is used to avoid the connector member;

[0012] The reset fitting is located between the seal and the drive assembly. The first abutting member and the second abutting member are provided with a first abutting portion and a second abutting portion on the side facing the seal. The first abutting portion and the second abutting portion form an abutting fit with the reset fitting.

[0013] In some embodiments, the driving end of the driving assembly is provided with a driving connector, the driving connector being snapped into the connector, and the driving connector driving the connector to move axially along the seal, the connector and the driving assembly.

[0014] In some embodiments, the accommodating cavity includes a transition cavity, a liquid storage cavity, a liquid accumulation cavity, and a liquid drainage cavity. The transition cavity communicates with the liquid accumulation cavity and the liquid drainage cavity. The liquid accumulation cavity is located between the liquid storage cavity and the liquid drainage cavity. The sealing element is disposed in the transition cavity. A first partition wall is disposed between the liquid storage cavity and the liquid accumulation cavity. A second partition wall is disposed between the liquid accumulation cavity and the liquid drainage cavity. A third partition wall is disposed on the side of the transition cavity facing the external environment.

[0015] In some embodiments, the seal includes a first sealing portion, a second sealing portion, and a connecting portion, wherein the connecting portion connects the first sealing portion and the second sealing portion, and the first sealing portion, the second sealing portion, and the connecting portion are integrally formed or separately formed.

[0016] In some embodiments, the first partition wall is provided with a first through hole, the second partition wall is provided with a second through hole, and the third partition wall is provided with a third through hole. The sealing member is disposed between the first through hole and the third through hole, and the sealing member passes through the second through hole. The first sealing part is used to seal and open the first through hole and the second through hole. The second sealing part is disposed on the side of the third through hole facing the transition cavity and is connected to the third partition wall.

[0017] In some embodiments, the first sealing portion is provided with a first sealing mating portion, which is used to seal the second through hole when the first sealing portion opens the first through hole;

[0018] The sealing element has a receiving groove on the side facing the third through hole, and the connecting element forms a snap-fit ​​engagement with the sealing element through the second through hole, thereby causing the connecting element to move the first sealing part.

[0019] In some embodiments, the first housing is provided with a first dispensing panel and a second dispensing panel, the first dispensing panel is provided with a first liquid outlet and a first liquid inlet, and the first liquid outlet is connected to the draining cavity;

[0020] The second dispensing panel includes a first cover and a first dispensing slot. The first cover is slidably disposed on the second dispensing panel. A first rotating fitting is disposed on the side of the first housing facing the first cover. A first rotating component is disposed on one end of the reset component connected to the second housing. The first rotating component and the first rotating fitting form a rotating fit to make the first cover slide, thereby dispensing the washing material in the first dispensing slot.

[0021] In some embodiments, the dispensing mechanism is provided with a starting station, a powder dispensing station, a waiting station, a first liquid dispensing station, and a second liquid dispensing station;

[0022] When the dispensing mechanism is in the starting position, the driving component is not working, the sealing member abuts against the first through hole, and the reset member abuts against the reset mating member under the drive of the first elastic member.

[0023] When the dispensing mechanism is in the powder feeding station, the driving component works. The driving component drives the connecting piece to move toward the driving end of the driving component. After the sealing piece leaves the first through hole, the reset piece rotates under the drive of the reset mating piece, thereby driving the first rotating piece to rotate. The first rotating piece and the first rotating mating piece rotate and cooperate to make the first cover slide, thereby dispensing the washing material in the first feeding tank.

[0024] When the distribution mechanism is in the waiting position, the drive component stops working, and the reset member drives the reset mating member to reset under the action of the first elastic member. The sealing member briefly leaves the first through hole and then resets to continue to abut against the first through hole.

[0025] When the dispensing mechanism is in the first liquid injection station, the drive assembly continues to work. The drive assembly drives the connector to move toward the drive end of the drive assembly. The first sealing part leaves the first through hole, and the first sealing mating part seals the second through hole. The washing liquid in the liquid storage cavity enters the transition cavity through the first through hole and enters the liquid accumulation cavity for storage.

[0026] When the dispensing mechanism is in the second liquid injection position, the drive assembly stops working, the first sealing part seals the first through hole, the first sealing mating part opens the second through hole, and the washing liquid located in the liquid accumulation cavity enters the drain cavity through the second through hole, is stored, and flows out of the dispensing mechanism through the first liquid outlet.

[0027] This application improves the user experience by moving the reset component to the drive end of the drive component, with the contact point between the reset component and the reset mating part as the vertex, and the angle C between the direction of the force of the reset component on the reset mating part and the plane containing the axis of the seal, the connector and the drive component, where 0°≤C≤20°. This prevents the reset component from exerting excessive force on the reset mating part, thereby reducing force imbalance and avoiding the problem of inconsistent vibration and noise during the start-up process of the reset component and the drive component.

[0040] 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 the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0044] In the dishwasher industry, the dispenser is a crucial component for dispensing detergent, and users frequently interact with it, directly impacting the overall user experience. In existing technologies, dispensers often generate excessive noise during detergent dispensing, leading to a poor user experience. Through research and experimentation, it has been discovered that in existing sealing sleeve reset structures, the solenoid valve periodically vibrates. Since the force exerted by the reset component on the reset mating part is not parallel to the axis between the reset component and the solenoid valve, a component force is generated. This component force causes the reset component to vibrate, which, unlike the solenoid valve vibration, results in noise and reduces the customer experience.

[0045] Therefore, the purpose of the embodiments of this application is to overcome the defects and deficiencies in the prior art and to provide a dispensing mechanism that aims to solve the problem of excessive noise in the dispensing mechanism when dispensing washing materials in the prior art.

[0046] like Figure 1 , Figure 2 and Figure 3 As shown, Figure 1 This is a schematic diagram of the structure of the dispensing mechanism in the powder feeding station and the first liquid feeding station states according to the embodiments of this application. Figure 2 This is a schematic diagram of the distribution mechanism in the following embodiments of the application, when it is in the starting position, waiting position, and second liquid dispensing position. Figure 3 yes Figure 1 An exploded view of the dispensing mechanism in this embodiment shows that the dispensing mechanism 1 includes a housing assembly 10, a sealing assembly 20, and a driving assembly 50. The housing assembly 10 includes a first housing 100 and a second housing 101, which together form a receiving cavity 102. In some embodiments, the first housing 100 is a front shell, and the second housing 101 is a rear shell. The first housing 100 faces the dishwasher washing space and is used to discharge washing liquid and solid waste into the washing space. The second housing 101, on the side facing away from the first housing 100, has a recessed receiving space 1027 facing the first housing 100. The sealing assembly 20 and the driving assembly 50 are disposed within the receiving space 1027.

[0047] like Figure 1 and Figure 3As shown, the sealing assembly 20 includes a sealing element 200, a connecting element 30, and a reset assembly 40. The sealing assembly 20 forms a sealed connection with the accommodating cavity 102. The connecting element 30 connects the sealing element 200 and the driving assembly 50. The driving assembly 50 drives the sealing element 200 through the connecting element 30, thereby controlling the sealing and opening of part of the accommodating cavity 102. A reset mating element 300 is provided on the connecting element 30, and the reset assembly 40 and the reset mating element 300 form a contact fit. In some embodiments, the material of the sealing member 200 may be, but is not limited to, waterproof silicone, and the sealing member 200 may be a sealing plug; the connecting member 30 may be a rigid rod; the reset mating member 300 may be a reset platform, and the reset mating member 300 abuts against the reset assembly 40; the drive assembly 50 may be a solenoid valve that drives the connecting member 30 to extend and retract; the drive end 500 may be a solenoid valve that drives the connection end between the connecting member 30 and the drive assembly 50 to move to a position close to the maximum position of the solenoid valve; and when the drive assembly 50 stops working, it will not lock the position of the connecting member 30, and the connecting member 30 may still slide. This configuration allows the reset assembly 40 to drive the sealing member 200 to reset through the reset mating member 300 after the solenoid valve stops working.

[0048] The reset assembly 40 needs to drive the reset mating part 300 to reset, thereby driving the seal 200 to reset. Simultaneously, if... Figure 1 and Figure 4 As shown, Figure 4 yes Figure 1The schematic diagram of the elevation structure of the distribution mechanism in the embodiment shows that the reset assembly 40 includes a reset member 400 and a first elastic member 401. The reset member 400 and the first elastic member 401 are disposed on the side of the second housing 101 away from the accommodating cavity 102. One end of the reset member 400 is rotatably disposed on the second housing 101, and the other end of the reset member 400 abuts against the reset mating member 300. A first fixing member 4003 is disposed between the two ends of the reset member 400. One end of the first elastic member 401 is connected to the second housing 101, and the other end of the first elastic member 401 is connected to the first fixing member 4003. The first elastic member 401 drives the reset member 400 to reset, thereby driving the sealing member 200 to reset. In some embodiments, the reset member 400 is a rotatable rod fixed to the second housing 101, and the first elastic member 401 is a spring. The two ends of the reset member 400 are recessed downwards and protrude from the first fixing member 4003. The two ends of the first elastic member 401 are fixing rings. One end of the first elastic member 401 is fixed to the first fixing member 4003, and the other end is fixed to the second fixing member 1028 on the second housing 101. The second fixing member 1028 is a rod protruding from the second housing 101, and the first elastic member 401 is always in a stretched state. This allows the reset member 400 to rotate around the fixed end of the reset member 400 and the second housing 101 when the solenoid valve stops working, using the elastic potential energy of the first elastic member 401. Since the reset mating member 300 abuts against the reset member 400 and the reset mating member is disposed on the connecting member 30, the reset member 400 will drive the connecting member 30 to move, thereby driving the sealing member 200 to reset.

[0049] like Figure 3 , Figure 4 and Figure 5 As shown, Figure 5 yes Figure 1 The enlarged structural diagram of the distribution mechanism at point A in the embodiment shows that in some embodiments, the reset member 400 includes a clearance groove 4000, a first abutment member 4001, and a second abutment member 4002. The clearance groove 4000 is disposed between the first abutment member 4001 and the second abutment member 4002. The clearance groove 4000 is configured to allow the reset member 400 to engage with the reset mating member 300 without hindering the movement of the connecting member 30. The reset mating member 300 is located between the sealing member 200 and the drive assembly 50. The first abutment member 4001... 01 and the second abutting member 4002 are provided with a first abutting part 4001a and a second abutting part (the same as the first abutting part, so it is not shown in the figure) on the side facing the sealing member 200. The first abutting part 4001a and the second abutting part form an abutting fit with the reset fitting member 300. The first abutting part 4001a and the second abutting part are protrusions at the abutting end of the reset member 400 and the reset fitting member 300. The angle and shape of the protrusions can make the abutting force between the reset fitting member 300 and the reset member 400 more reasonable.

[0050] like Figure 3 and Figure 4 As shown, the drive end 500 of the drive assembly 50 is provided with a drive connector 501, which is snapped into connection with the connector 30. The drive connector 501 drives the connector 30 to move axially along the seal 200, the connector 30, and the drive assembly 50. In some embodiments, the drive connector 501 extends from the drive end 500 of the drive assembly 50, and is snapped into connection with the connector 30. The drive assembly 50 drives the drive connector 501 to move, thereby driving the seal 200 to move through the connector 30. To minimize the noise of the distributor, this application arranges the seal 200, connector 30, drive connector 501, and drive end 500 coaxially. Figure 4 (in the X direction), this setting allows the drive connector 501 to always move axially when it drives the seal 200 and connector 30 to move, without any deviation in direction;

[0051] In existing technologies, the drive assembly 50 mostly uses alternating current. The current of the alternating current regularly changes to 0A. When the current reaches 0A, the solenoid valve stops momentarily, causing the reset piece 400 to spring back. After the current resumes, the drive connector 501 continues to drive the reset piece 400 back to its original position. Noise is generated during the process of the reset piece 400 springing back to its original position. However, in this application, as... Figure 4 As shown, when the drive assembly 50 moves the connector 30 to the drive end 500 of the drive assembly 50, with the contact point between the reset assembly 40 and the reset mating part 300 as the vertex, the angle C between the direction of the force of the reset assembly 40 on the reset mating part 300 and the plane containing the axes of the seal 200, connector 30, and drive assembly 50 is defined as 0°≤C≤20°. C can be, but is not limited to, 3°, 6°, 9°, 12°, or 15°. C can be either the angle C1 between the direction of the force of the reset assembly 40 on the reset mating part 300 and the upper side of the plane containing the axes of the seal 200, connector 30, and drive assembly 50, or the angle C2 between the direction of the force of the reset assembly 40 on the reset mating part 300 and the lower side of the plane containing the axes of the seal 200, connector 30, and drive assembly 50. Figure 4 The demonstration shows two scenarios when the drive assembly 50 moves the connector 30 to the drive end 500 of the drive assembly 50. Other scenarios at angle C are different. Figure 4 The principle is similar, so it will not be elaborated further. This arrangement is to ensure that when the reset component 400 of the reset assembly 40 is brought to the drive end 500 by the drive assembly 50, the contact force between the reset component 400 and the reset mating component 300 is aligned with the axial direction of the seal 200, the connector 30, the drive connector 501, and the drive end 500. Figure 4The included angle C between the X direction and the center direction will not be too large, so that the reset component 400 and the drive component 50 will basically maintain the same direction of vibration during the springback and restoration to the original position, thereby reducing noise.

[0052] This application improves the user experience by moving the reset assembly 40 to the drive end 500 of the drive assembly 50, with the contact point between the reset assembly 40 and the reset mating part 300 as the vertex, and the angle C between the direction of the force of the reset assembly 40 on the reset mating part 300 and the plane containing the axes of the seal 200, the connector 30 and the drive assembly 50, where 0°≤C≤20°. This prevents the reset assembly 40 from generating excessive force on the reset mating part 300, thereby reducing force imbalance and avoiding the problem of noise caused by inconsistent vibration between the reset assembly 40 and the drive assembly 50 during the startup process.

[0053] like Figure 6 , Figure 7 and Figure 10 As shown, Figure 6 yes Figure 2 Exploded view of the dispensing mechanism in the embodiment. Figure 7 yes Figure 2 The distribution mechanism in the embodiment is shown in the BB cross-sectional structural diagram. Figure 10 yes Figure 1 The embodiment of the dispensing mechanism is shown in the CC cross-sectional view. The accommodating cavity 102 includes a transition cavity 1020, a liquid storage cavity 1021, a liquid accumulation cavity 1025, and a liquid drainage cavity 1023. The transition cavity 1020 is connected to the liquid accumulation cavity 1025 and the liquid drainage cavity 1023. The liquid accumulation cavity 1025 is located between the liquid storage cavity 1021 and the liquid drainage cavity 1023. A sealing member 200 is disposed in the transition cavity 1020. A first partition wall 1022 is disposed between the liquid storage cavity 1021 and the liquid accumulation cavity 1025. A second partition wall 1024 is disposed between the liquid accumulation cavity 1025 and the liquid drainage cavity 1023. A third partition wall 1026 is disposed on the side of the transition cavity 1020 facing the external environment. In some embodiments, the transition cavity 1020 is disposed in the accommodating space 1027 to facilitate cooperation with the sealing member 200. The transition cavity 1020 is connected to the liquid accumulation cavity 1025 and the drain cavity 1023 respectively, so that the sealing member 200 can simultaneously control the sealing and opening of the liquid storage cavity 1021 and the liquid accumulation cavity 1025, as well as the liquid accumulation cavity 1025 and the drain cavity 1023.

[0054] like Figure 6 , Figure 7 and Figure 10As shown, the sealing element 200 includes a first sealing part 2001, a second sealing part 2003, and a connecting part 2004. The connecting part 2004 connects the first sealing part 2001 and the second sealing part 2003. The first sealing part 2001, the second sealing part 2003, and the connecting part 2004 are integrally formed or separately formed. A first through hole 1022a is provided on the first partition wall 1022, and a second through hole 1024a is provided on the second partition wall 1024. The sealing element 200 is disposed between the first through hole 1022a and the third through hole 1026a, and the sealing element 200 passes through the second through hole 1024a. The first sealing part 2001 is used to seal and open the first through hole 1022a and the second through hole 1024a. The second sealing part 2003 is disposed on the side of the third through hole 1026a facing the transition cavity 1020 and is connected to the third partition wall 1026. In some embodiments, a first sealing engagement part 2002 is provided on the first sealing part 2001. The first sealing part 2001 is an end plug, and the first sealing engagement part 2002 is an umbrella-shaped plug. The first sealing engagement part 2002 is used to seal the second through hole 1024a when the first sealing part 2001 opens the first through hole 1022a. Specifically, when the first sealing part 2001 is driven by the driving assembly 50 and the connecting member 30, it moves from the first through hole 1022a to the second partition wall 1024. At this time, the first sealing engagement part 2002 will abut against the second partition wall 1024 and seal the second through hole 1024a. At this time, the dishwashing liquid can flow into the first through hole 1022a but will not flow into the second through hole 1024a. This arrangement can reduce the leakage of liquid during the movement of the dispensing mechanism 1.

[0055] In some embodiments, such as Figure 7 As shown, the sealing member 200 has a receiving groove 201 on the side facing the third through hole 1026a. The connecting member 30 passes through the third through hole 1026a and forms a snap-fit ​​engagement with the sealing member 200, thereby causing the connecting member 30 to move the first sealing part 2001. In some embodiments, the second sealing part 2003 is a rubber part with holes. The connecting member 30 passes through the third through hole 1026a and through the rubber part to snap-fit ​​with the receiving groove 201. When the driving assembly 50 drives the connecting member 30 to move towards the driving end 500, the connecting member 30 snaps with the sealing member 200. At the same time, the connecting member 30 drives the first sealing part 2001 to move and compresses the second sealing part 2003 towards the third through hole 1026a. The elasticity of the second sealing part 2003 can buffer the movement of the connecting member 30.

[0056] like Figure 8 and Figure 9 As shown, Figure 8 yes Figure 1 Another perspective structural diagram of the distribution mechanism in the embodiment. Figure 9 yes Figure 8 A schematic diagram of the explosion mechanism of the first housing in the embodiment of the distribution mechanism. The first housing 100 is provided with a first dispensing panel 1000 and a second dispensing panel 1010. The first dispensing panel 1000 is provided with a first liquid outlet 1002 and a first liquid inlet 1001. The first liquid outlet 1002 is connected to the draining cavity 1023. In some embodiments, the first liquid inlet 1001 is also provided with a vent hole 1003, which is used to balance the air pressure inside and outside the distribution mechanism 1. The second dispensing panel 1010 includes a first cover 1011 and a first dispensing slot 1012. The first cover 1011 is slidably disposed on the second dispensing panel 1010. A first rotating engagement member 1013 is provided on the side of the first housing 100 facing the first cover 1011. A first rotating member 402 is provided on one end of the reset member 400 connected to the second housing 101. The first rotating member 402 and the first rotating engagement member 1013 form a rotating engagement to make the first cover 1011 slide, thereby dispensing the washing material in the first dispensing slot 1012.

[0057] like Figure 1 , Figure 2 , Figure 6 , Figure 7 and Figure 10 As shown, the distribution mechanism 1 is equipped with a starting station, a powder feeding station, a waiting station, a first liquid feeding station, and a second liquid feeding station;

[0058] When the distributing mechanism 1 is in the starting position, the drive assembly 50 is not working, the sealing member 200 abuts against the first through hole 1022a, and the reset member 400 abuts against the reset mating member 300 under the drive of the first elastic member 401.

[0059] When the dispensing mechanism 1 is in the powder feeding position, the drive assembly 50 is working. The drive assembly 50 drives the connecting piece 30 to move toward the drive end 500 of the drive assembly 50. After the sealing piece 200 leaves the first through hole 1022a, the reset piece 400 rotates under the drive of the reset mating piece 300, thereby driving the first rotating piece 402 to rotate. The first rotating piece 402 and the first rotating mating piece 1013 rotate and engage to make the first cover 1011 slide, thereby dispensing the washing material in the first dispensing tank 1012. In this state, the drive assembly 50 does not need to work for a long time. It only needs to rotate the reset piece 400 to dispense the dishwashing solids in the first dispensing tank 1012 and then stop working.

[0060] When the dispensing mechanism 1 is in the waiting position, the drive assembly 50 stops working. The reset member 400 drives the reset mating member 300 to reset under the action of the first elastic member 401. The sealing member 200 briefly leaves the first through hole 1022a and then resets to continue to abut against the first through hole 1022a. Because the powder dispensing process of the dispenser is relatively short, the dishwashing liquid will be stored in the liquid accumulation chamber after passing through the first through hole 1022a and will not flow into the drain chamber 1023 through the second through hole 1024a.

[0061] When the dispensing mechanism 1 is in the first liquid dispensing position, the drive assembly 50 continues to work. The drive assembly 50 drives the connector 30 to move toward the drive end 500 of the drive assembly 50. The first sealing part 2001 leaves the first through hole 1022a, and the first sealing mating part 2002 seals the second through hole 1024a. The washing liquid in the liquid storage cavity 1021 enters the transition cavity 1020 through the first through hole 1022a and enters the liquid accumulation cavity 1025 for storage until the liquid in the liquid accumulation cavity 1025 is filled to the dispensing amount.

[0062] When the distribution mechanism 1 is in the second liquid injection position, the drive assembly 50 stops working, the first sealing part 2001 seals the first through hole 1022a, the first sealing mating part 2002 opens the second through hole 1024a, and the washing liquid located in the liquid accumulation chamber 1025 enters the drain chamber 1023 through the second through hole 1024a for accumulation and flows out of the distribution mechanism 1 through the first liquid outlet 1002.

[0063] The dispensing mechanism 1 will repeat the first and second dispensing stations until the amount of washing liquid dispensed into the dishwasher reaches the set value.

Any equivalent changes in mechanism or process made based on the content of this application specification and drawings, or direct or indirect applications in other related technical fields, are similarly included in the patent protection scope of this application.
