Description
Technical Field
[0001] This application relates to the field of household appliance technology, particularly to dishwasher or washing machine products, and especially to a dispenser. Background Technology
[0002] In related technologies, the dispenser has a motor, a housing, a first dispensing component and a second dispensing component. The housing has two chambers, which are respectively filled with a first material and a second material. The first dispensing component and the second dispensing component are used to dispense the materials in the two chambers respectively.
[0003] The first dispensing component opens the corresponding chamber through the cooperation of gears, levers and cover, and the first material flows out or falls out of the chamber under the action of gravity, thereby realizing the dispensing;
[0004] The second dispensing component uses a peristaltic pump structure to draw in the second material in the corresponding chamber and then discharge it, thereby achieving dispensing;
[0005] The first dispensing component has a first gear, the second dispensing component has a second gear, the output shaft of the motor meshes with the first gear, the first gear meshes with the second gear, and when the motor rotates, the first gear and the second gear rotate simultaneously.
[0006] When used for the first time, there is no second material in the delivery pipe of the peristaltic pump structure. After the second dispensing component starts to operate for a period of time, the delivery pipe gradually fills up, and then the second material is dispensed. Therefore, the response time from the action of the second dispensing component to the dispensing is longer than the response time from the action of the first dispensing component to the dispensing, which allows the first material to be dispensed before the second material.
[0007] However, during subsequent use, since the conveying pipe is filled with the second material, the second dispensing component will dispense the second material as soon as it is activated. This makes the response time from the activation of the second dispensing component to the dispensing the same as the response time from the activation of the first dispensing component to the dispensing the first material, which in turn makes the first material and the second material dispensed at the same time.
[0008] When the first and second materials are added simultaneously, the washing effect on the items being cleaned will decrease. Utility Model Content
[0009] To solve at least one of the above-mentioned technical problems, the following technical solutions are provided:
[0010] A dispenser, comprising:
[0011] Housing, drive assembly, first dispensing assembly, and second dispensing assembly;
[0012] The housing has a first chamber and a second chamber, the first dispensing component is used to dispense material into the first chamber, and the second dispensing component is used to dispense material into the second chamber;
[0013] The first dispensing component has a first input gear, and the second dispensing component has a second input gear;
[0014] The drive assembly includes a motor and a first output gear, the first output gear being configured to move between a first position and a second position;
[0015] When the motor rotates in the first direction, the first output gear moves to the first position and meshes with the first input gear to drive the first dispensing component to work;
[0016] When the motor rotates in a second direction opposite to the first direction, the first output gear moves to a second position and meshes with the second input gear to drive the second delivery component to work.
[0017] Because the first output gear is configured to move between a first position and a second position, when the motor rotates in the first direction, the first output gear moves to the first position and meshes with the first input gear to drive the first dispensing component. When the motor rotates in the second direction opposite to the first direction, the first output gear moves to the second position and meshes with the second input gear to drive the second dispensing component. In this way, by controlling the selective meshing of the first output gear with the first input gear or the second input gear through the two rotation directions of the motor, time-sharing drive of the first dispensing component and the second dispensing component is realized. This ensures that the materials in the first chamber and the second chamber can be dispensed in sequence, regardless of whether it is the first time using the equipment, thereby guaranteeing the washing effect on the items being cleaned.

[0036] To make the objectives, technical solutions, and advantages of this application clearer, the specific embodiments are further described below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.
[0037] like Figures 1 to 8 As shown:
[0038] A dispenser includes: a housing 100, a drive assembly 200, a first dispensing assembly 300, and a second dispensing assembly 400; the housing 100 has a first chamber 11 and a second chamber 12, the first chamber 11 for containing a first material (specifically, powdered dishwashing powder), and the second chamber 12 for containing a second material (specifically, liquid rinse aid); the first dispensing assembly 300 is used to dispense the material in the first chamber 11, and the second dispensing assembly 400 is used to dispense the material in the second chamber 12; the first dispensing assembly 300 has a first input gear 31, and the second dispensing assembly 400 has a second input gear 41; the drive assembly 200 includes a motor 21 and a first output gear 22, the first output gear 22 being configured to move between a first position and a second position.
[0039] When the first output gear 22 is in the first position, the first output gear 22 meshes with the first input gear 31 and disengages from the second input gear 41.
[0040] When the first output gear 22 is in the second position, the first output gear 22 meshes with the second input gear 41 and the first output gear 22 is disengaged from the first input gear 31.
[0041] When the motor 21 rotates in the first direction (meaning the output shaft of the motor 21 rotates in the first direction, rather than the motor 21 rotating in the first direction), the first output gear 22 moves to the first position and meshes with the first input gear 31 to drive the first dispensing component 300 to work.
[0042] When the motor 21 rotates in a second direction opposite to the first direction (meaning that the output shaft of the motor 21 rotates in the second direction, rather than the motor 21 rotating in the second direction), the first output gear 22 moves to the second position and meshes with the second input gear 41 to drive the second dispensing assembly 400 to work.
[0043] Since the first output gear 22 is configured to move between a first position and a second position, when the motor 21 rotates in the first direction, the first output gear 22 moves to the first position and meshes with the first input gear 31 to drive the first dispensing component 300 to work. When the motor 21 rotates in the second direction opposite to the first direction, the first output gear 22 moves to the second position and meshes with the second input gear 41 to drive the second dispensing component 400 to work. In this way, by controlling the selective meshing of the first output gear 22 with the first input gear 31 or the second input gear 41 through the two rotation directions of the motor 21, the time-sharing drive of the first dispensing component 300 and the second dispensing component 400 is realized. This ensures that the materials in the first chamber 11 and the second chamber 12 can be dispensed in a preset order, regardless of whether it is the first time using the equipment. This avoids mutual cancellation or interference that may occur due to the simultaneous dispensing of materials, thereby ensuring the washing effect on the cleaned items.
[0044] The drive assembly 200 also includes a connecting rod 24, which has a first connecting portion 241 and a second connecting portion 242.
[0045] The first connecting part 241 is coaxially arranged with the output shaft of the motor 21. The first connecting part 241 can rotate relative to the body of the motor 21. Specifically, in this embodiment, the motor 21 has a first connecting mating part 211, which protrudes from the body of the motor 21 along the axial direction of the motor 21 and surrounds the outside of the output shaft of the motor 21. The first connecting part 241 is sleeved on the first connecting mating part 211. Effect: By setting the rotation support point of the connecting rod 24 on the fixed first connecting mating part 211, on the one hand, wear caused by direct contact between the connecting rod 24 and the output shaft of the motor 21 can be avoided, effectively extending the service life and stability of the motor 21. On the other hand, the output shaft of the motor 21 only needs to drive the second output gear 23 to rotate, without having to bear the additional radial force and vibration caused by the swing of the connecting rod 24, which helps to ensure the smooth operation of the system.
[0046] In some embodiments, the first connecting part 241 can also be directly sleeved on the output shaft of the motor 21, which simplifies the structure.
[0047] The second connecting part 242 is coaxially arranged with the first output gear 22 and connected to the first output gear 22. The first output gear 22 can rotate relative to the second connecting part 242. Specifically, in this embodiment, the second connecting part 242 protrudes from the body of the connecting rod 24, and the first output gear 22 is sleeved on the second connecting part 242. In some embodiments, the second connecting part 242 may also be sleeved on the shaft of the first output gear 22. Specifically, the second connecting part 242 has a through hole, and the shaft of the first output gear 22 passes through at least part of the through hole.
[0048] The first output gear 22 and the second connecting part 242 are axially limited to prevent the first output gear 22 from dislodging. Specifically, the first output gear 22 and the second connecting part 242 can be axially limited by means of snap-fit or other methods.
[0049] In this way, the constraint of the connecting rod 24 provides a clear and controllable arc-shaped motion trajectory for the movement of the first output gear 22, enabling the first output gear 22 to move reliably between the first position and the second position.
[0050] The drive assembly 200 also includes a second output gear 23, which is connected to the output shaft of the motor 21 and meshes with the first output gear 22.
[0051] In this way, the second output gear 23 enables the first output gear 22 to rotate. With the further constraint of the connecting rod 24 or the guide groove (meaning at least one of the first guide groove 51 and the second guide groove 52 mentioned below), the first output gear 22 can revolve, that is, move between the first position and the second position.
[0052] In this embodiment, the second output gear 23 is sleeved on the output shaft of the motor 21. The second output gear 23 is circumferentially limited to the output shaft of the motor 21, or the second output gear 23 is fixed to the output shaft of the motor 21, so that the output shaft of the motor 21 can drive the second output gear 23 to rotate.
[0053] The minimum distance between the second output gear 23 and the first input gear 31 is less than the maximum diameter of the first output gear 22;
[0054] The minimum distance between the second output gear 23 and the second input gear 41 is less than the maximum diameter of the first output gear 22.
[0055] Since the minimum distance between the second output gear 23 and the first input gear 31 is less than the maximum diameter of the first output gear 22, the second output gear 23 and the first input gear 31 can limit the first output gear 22 and prevent the first output gear 22 from moving from the second position to the first position and crossing the first position.
[0056] Since the minimum distance between the second output gear 23 and the second input gear 41 is less than the maximum diameter of the first output gear 22, the second output gear 23 and the second input gear 41 can limit the first output gear 22 and prevent the first output gear 22 from moving beyond the second position when it moves from the first position to the second position.
[0057] In this way, without the need for additional sensors or complex electronic control programs, the movement position of the second output gear 23 can be controlled through the limiting action at the two locations mentioned above, thus improving the robustness of the system.
[0058] The housing 100 includes a first part 101 and a second part 102, which are fixedly connected, specifically by fusion welding. A first chamber 11 is located in the first part 101, specifically, the first chamber 11 is a groove in the first part 101. A second chamber 12 is located between the first part 101 and the second part 102.
[0059] The first dispensing assembly 300 includes a first cover 33, which is movable (e.g., rotated or slidable) relative to the first split body 101 to open or close the first chamber 11. Specifically, the first cover 33 is connected to the first split body 101, and the first cover 33 is slidable or rotated relative to the first split body 101 to open or close the first chamber 11. The first dispensing assembly 300 also includes a locking mechanism 32, which is capable of engaging or disengaging from the first cover 33; a first input gear 31 is drive-connected to the locking mechanism 32.
[0060] The second dispensing assembly 400 includes a conveying pipe 43 and a rotary extrusion mechanism 42. One end of the conveying pipe 43 is connected to the second chamber 12, and the other end of the conveying pipe 43 is directly connected to the outside (such as the washing chamber of a dishwasher), or indirectly connected to the outside (such as the washing chamber of a dishwasher). Specifically, the other end of the conveying pipe 43 is connected to a dispensing channel provided in the housing 100, and the dispensing channel can be connected to the outside (such as the washing chamber of a dishwasher). A portion of the conveying pipe 43 is fitted onto the rotary extrusion mechanism 42, which is used to extrude the conveying pipe 43 to make the fluid in the conveying pipe 43 flow. The second input gear 41 is drivenly connected to the rotary extrusion mechanism 42.
[0061] The following describes the working process of the distributor in this application:
[0062] In the dispenser of this application, the first material is dispensed before the second material.
[0063] The process of adding the first material:
[0064] When the first material needs to be added, the motor 21 starts in the first direction (forward rotation). The motor 21 drives the first output gear 22 to rotate through the second output gear 23.
[0065] Driven by the reverse rotation of the motor 21, the first output gear 22 moves from the middle position or the second position to the first position under the constraint of the connecting rod 24, until it is fully engaged with the first input gear 31 and completely disengaged from the second input gear 41.
[0066] Power is transmitted to the first dispensing component 300 through the first output gear 22 and the first input gear 31. The first input gear 31 drives the locking mechanism 32 to release the lock on the first cover 33.
[0067] After the latch is released, the first cover 33 opens the first chamber 11 (or the slot of the first chamber 11) under the action of gravity or the built-in elastic element, so that the first material inside falls out under the action of gravity, completing the first material delivery.
[0068] The process of adding the second material:
[0069] When a second material needs to be added, the motor 21 starts in the second direction (reverse direction). The motor 21 drives the first output gear 22 to rotate through the second output gear 23.
[0070] Driven by the motor 21, the first output gear 22 moves from the middle position or the first position to the second position under the constraint of the connecting rod 24, until it is fully engaged with the second input gear 41 and completely separated from the first input gear 31.
[0071] Power is transmitted to the second dispensing assembly 400 via the first output gear 22 and the second input gear 41. The second input gear 41 drives the rotary extrusion mechanism 42 to rotate. The rotary extrusion mechanism 42 continuously extrudes the conveying pipe 43, generating a peristaltic pump effect, pumping the second material out of the second chamber 12, thus completing one dispensing of the second material.
[0072] After the first and second materials have been dispensed, the first cover 33 can be closed manually and relocked by the locking mechanism 32 to prepare for the next dispensing.
[0073] Figure 9 Another embodiment is shown, in which:
[0074] The drive assembly 200 also includes a connecting rod 24, which has a first connecting portion 241 and a second connecting portion 242.
[0075] The first connecting part 241 is coaxially arranged with the output shaft of the motor 21. The first connecting part 241 can rotate relative to the body of the motor 21. Specifically, in this embodiment, the motor 21 has a first connecting mating part 211, which protrudes from the body of the motor 21 along the axial direction of the motor 21 and surrounds the outside of the output shaft of the motor 21. The first connecting part 241 is sleeved on the first connecting mating part 211. In this way, the rotation support point of the connecting rod 24 is set on the fixed first connecting mating part 211. On the one hand, it can avoid the wear caused by direct contact between the connecting rod 24 and the output shaft of the motor 21, effectively extending the service life and stability of the motor 21. On the other hand, the output shaft of the motor 21 only needs to drive the second output gear 23 to rotate, without having to bear the additional radial force and vibration caused by the swing of the connecting rod 24, which helps to ensure the smooth operation of the system.
[0076] In some embodiments, the first connecting part 241 can also be directly sleeved on the output shaft of the motor 21, which simplifies the structure.
[0077] The second connecting part 242 is coaxially arranged with the first output gear 22. The second connecting part 242 is connected to the first output gear 22, and the first output gear 22 can rotate relative to the second connecting part 242. Specifically, in this embodiment, the second connecting part 242 protrudes from the body of the connecting rod 24, and the first output gear 22 is sleeved on the second connecting part 242. In some embodiments, the second connecting part 242 may also have a second through hole, and the shaft of the first output gear 22 may at least partially pass through the second through hole.
[0078] The first output gear 22 and the second connecting part 242 are axially limited to prevent the first output gear 22 from dislodging. Specifically, the first output gear 22 and the second connecting part 242 can be axially limited by means of snap-fit or other methods.
[0079] In this way, the constraint of the connecting rod 24 provides a clear and controllable arc-shaped motion trajectory for the movement of the first output gear 22, enabling the first output gear 22 to move reliably between the first position and the second position.
[0080] The distributor also has a first guide groove 51, which is arc-shaped. The shaft of the first output gear 22 is at least partially located in the first guide groove 51, and the shaft of the first output gear 22 can slide along the first guide groove 51 to a first position and a second position.
[0081] The distributor also has a second guide groove 52, which is arc-shaped and is disposed opposite to the first guide groove 51. The second guide groove 52 and the first guide groove 51 are respectively located on both sides of the first output gear 22. The two ends of the shaft of the first output gear 22 are at least partially located in the second guide groove 52 and the first guide groove 51, respectively.
[0082] In this way, the guide groove and the connecting rod 24 form a dual constraint on the motion trajectory of the first output gear 22: First, the guide groove provides an arc-shaped guide rail for the shaft of the first output gear 22, making its movement smoother and transferring the sliding friction part to the guide groove, thereby protecting other components; second, compared with the cantilever support of the connecting rod 24 alone, the guide groove provides an additional support point, improving the stability of the first output gear 22 in the meshing state and reducing vibration and deformation; third, the connecting rod 24 determines the center of the motion trajectory, and the guide groove limits the radius of the motion trajectory. When there is an assembly gap or wear at the hinge point of the connecting rod 24, the guide groove can correct the trajectory and prevent position drift. Conversely, if there is a manufacturing error in the guide groove, the rigid constraint of the connecting rod 24 can also ensure basic functions. The two serve as backups or complements to each other, improving the reliability of the system.
[0083] Furthermore, since the minimum distance between the second output gear 23 and the first input gear 31 is less than the maximum diameter of the first output gear 22, the second output gear 23 and the first input gear 31 can limit the first output gear 22. Similarly, since the minimum distance between the second output gear 23 and the second input gear 41 is less than the maximum diameter of the first output gear 22, the second output gear 23 and the second input gear 41 can limit the first output gear 22. Together with the first guide groove 51 and the second guide groove 52, the two limiting positions and the two guide grooves (the first guide groove 51 and the second guide groove 52) complement each other in limiting the first output gear 22. When the accuracy of one side deviates, the limiting position of the first output gear 22 can still be guaranteed by the limiting position of the other side, thereby ensuring that the first output gear 22 meshes with the first input gear 31 in the first position and with the second input gear 41 in the second position.
[0084] Figure 10 Another embodiment is shown, in which:
[0085] The drive assembly 200 does not have the aforementioned connecting rod 24.
[0086] The distributor also has a first guide groove 51, which is arc-shaped. The shaft of the first output gear 22 is at least partially located in the first guide groove 51, and the shaft of the first output gear 22 can slide along the first guide groove 51 to a first position and a second position.
[0087] The distributor also has a second guide groove 52, which is arc-shaped and is disposed opposite to the first guide groove 51. The second guide groove 52 and the first guide groove 51 are respectively located on both sides of the first output gear 22. The two ends of the shaft of the first output gear 22 are at least partially located in the second guide groove 52 and the first guide groove 51, respectively.
[0088] In this way, the movement trajectory of the first output gear 22 is constrained by the guide groove. Compared with the method with the connecting rod 24, this method can simplify the parts and assembly. In addition, the elimination of the connecting rod 24 is conducive to the flattening of the drive component 200 structure, which in turn is conducive to the flattening of the dispenser, and thus facilitates the placement of the dispenser in spaces such as dishwashers or washing machines.
[0089] The above examples illustrate the principles and implementation methods of this application. The descriptions of the embodiments are merely for the purpose of helping to understand the technical solutions and core ideas of this application. It should be noted that those skilled in the art can make various improvements and modifications to this application without departing from its principles, and these improvements and modifications also fall within the protection scope of this application.
