[0041] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

If the specific posture changes, the directional indication will also change accordingly.

[0043] In this application, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0044] In addition, the descriptions of "first", "second", etc. in this application are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0045] The first aspect of the present application discloses a delivery device, Figure 1 、 Figure 2 and Figure 3 As shown, in some embodiments, the dispensing device includes a first actuator 1000, a second actuator 2000, a third actuator 3000 and a driving mechanism 4000. The first actuator 1000 is used to control the dispensing of the first detergent, the second actuator 2000 is used to control the dispensing of the second detergent, and the third actuator 3000 is used to control the dispensing of the third detergent. That is, the dispensing device is provided with three positions for storing the first detergent, the second detergent and the third detergent, respectively, namely the first cavity 6100 for storing the first detergent, the second cavity 6200 for storing the second detergent, and the third cavity 6300 for storing the third detergent. The first actuator 1000 controls the dispensing of the first detergent, which means that under the activity of the first actuator 1000, the first detergent can be separated from the position for storing the first detergent (the first cavity 6100) and be directly or indirectly dispensed into the washing cavity. The second actuator 2000 controls the dispensing of the second detergent, which means that under the activity of the second actuator 2000, the second detergent can be separated from the position for storing the second detergent (the second cavity 6200) and be directly or indirectly dispensed into the washing cavity. The third actuator 3000 controls the dispensing of the third detergent, which means that under the activity of the third actuator 3000, the third detergent can be separated from the position for storing the detergent (the third cavity 6300) and be directly or indirectly dispensed into the washing cavity.

[0046] The first detergent is one of the detergents and can be designed to be used primarily for decontamination and cleaning. The second detergent is one of the detergents and can be designed to be used primarily for decontamination and cleaning. The third detergent is one of the detergents and can be designed to assist in decontamination and cleaning, such as accelerating drying, increasing gloss, antibacterial, and deodorizing. It is understandable that the first detergent, the second detergent, and the third detergent are not limited to the aforementioned examples and can also be other types. Taking the application of the dispensing device to a washing appliance as an example, the first detergent can be a liquid detergent, such as dishwashing liquid, the second detergent can be a solid detergent, such as dishwashing powder or dishwashing blocks, and the third detergent can be a liquid detergent, such as a rinse aid, a deodorant, and the like.

[0047] The movement of the first actuator 1000, the second actuator 2000 and the third actuator 3000 needs to be realized by the driving mechanism 4000. The driving mechanism 4000 is a component that can output power. Through the setting of the driving mechanism 4000, the driving mechanism 4000 is suitable for driving the movement of the first actuator 1000, the second actuator 2000 and the third actuator 3000. It can be understood that the driving mechanism 4000 is suitable for driving the movement of the first actuator 1000, the second actuator 2000 and the third actuator 3000, which means that when the first detergent needs to be added, the driving mechanism 4000 can drive the first actuator 1000 to move; when the second detergent needs to be added, the driving mechanism 4000 can drive the second actuator 2000 to move; when the third detergent needs to be added, the driving mechanism 4000 can drive the third actuator 3000 to move. When the driving mechanism 4000 drives the first actuator 1000 to move, the first actuator 1000 moves to control the dispensing of the first detergent. When the driving mechanism 4000 drives the second actuator 2000 to move, the second actuator 2000 moves to control the dispensing of the second detergent. When the driving mechanism 4000 drives the third actuator 3000 to move, the third actuator 3000 moves to control the dispensing of the third detergent. It is understood that under the drive of the driving mechanism 4000, the movement of the first actuator 1000, the movement of the second actuator 2000, and the movement of the third actuator 3000 can take various forms, including but not limited to rotation, swinging, translation, curvilinear motion, linear reciprocating motion, or compound motion (e.g., rotation followed by translation), and the same applies to the movement of other components.

[0048] Taking the dispensing device as an example, which includes but is not limited to a dishwasher, and specifically described in detail with reference to a dishwasher, the following can be done: the driving mechanism 4000 drives the first actuator 1000 and the third actuator 3000 to move. The driving mechanism 4000 drives the first actuator 1000 to move, causing the first actuator 1000 to control the dispensing of the first detergent, thereby cleaning the dishes. The driving mechanism 4000 drives the third actuator 3000 to move, causing the third actuator 3000 to control the dispensing of the third detergent, thereby improving the drying effect and increasing the gloss of the dishes. It can also be: the driving mechanism 4000 drives the second actuator 2000 and the third actuator 3000 to move, the driving mechanism 4000 drives the second actuator 2000 to move, so that the second actuator 2000 controls the addition of the second detergent, thereby achieving the cleaning of the dishes, and the driving mechanism 4000 drives the third actuator 3000 to move, so that the third actuator 3000 controls the addition of the third detergent, thereby improving the drying effect of the dishes and increasing the glossiness of the dishes.

[0049] It can be seen that, in this embodiment, the driving mechanism 4000 is provided, and the driving mechanism 4000 is configured to drive the first actuator 1000, the second actuator 2000 and the third actuator 3000 to move. In this way, the dispensing of various types of detergents can be controlled by the same set of driving mechanisms 4000. Compared with the dispensing device in the related art, the number of driving mechanisms 4000 is greatly reduced, which is conducive to reducing the cost of the dispensing device and reducing the size of the dispensing device.

[0050] Combine Figures 4 to 7As shown, in some embodiments, the driving mechanism 4000 includes a power source 4001 and a connecting assembly 4002. The power source 4001 and the connecting assembly 4002 cooperate to achieve output. The connecting assembly 4002 plays a transmission role between the power source 4001 and the actuator (the first actuator 1000, the second actuator 2000, and the third actuator 3000). The power source 4001 is suitable for moving along a first direction and a second direction. The first direction and the second direction are opposite, that is, the power source 4001 can move along both the first direction and the second direction. When the power source 4001 moves along the first direction, the power source 4001 is suitable for driving the connecting assembly 4002 to move. The movement of the connecting assembly 4002 thereby drives the movement of the first actuator 1000, and the movement of the first actuator 1000 can control the dispensing of the first detergent. When the power source 4001 moves along the second direction, the power source 4001 is suitable for driving the connecting component 4002 to move. The movement of the connecting component 4002 thereby drives the second actuator 2000 and the third actuator 3000 to move. The movement of the second actuator 2000 can control the addition of the second detergent, and the movement of the third actuator 3000 can control the addition of the third detergent.

[0051] In this embodiment, the movement of the power source 4001 along the first direction and along the second direction can drive the connecting assembly 4002 to produce different movements. That is, the movement of the connecting assembly 4002 when the power source 4001 moves along the first direction is different from the movement when the power source 4001 moves along the second direction. This can drive the corresponding first actuator 1000, second actuator 2000, and third actuator 3000. The same power source 4001 can achieve selective delivery of the delivery device, which helps reduce the structural complexity of the drive mechanism 4000. It is understandable that the movement of the power source 4001 along the first direction and along the second direction can be rotational, translational, or other forms.

[0052] For example, the attached figure shows a power source 4001, and the dispensing device stores the first detergent and the third detergent, but does not store the second detergent. When the first detergent and the third detergent are selected to be dispensed, the power source 4001 moves along the first direction, thereby driving the connecting component 4002 to move, so that the connecting component 4002 drives the first actuator 1000 to move, and the first actuator 1000 moves to achieve the dispensing of the first detergent; the power source 4001 moves along the second direction, thereby driving the connecting component 4002 to move, so that the connecting component 4002 drives the second actuator 2000 and the third actuator 3000 to move, and the second actuator 2000 moves. Since the dispensing device does not store the second detergent, although the second actuator 2000 moves, no second detergent is dispensed, and the third actuator 3000 moves to achieve the dispensing of the third detergent.

[0053] As another example, a power source 4001 is shown, and the dispensing device stores the second detergent and the third detergent, and stores or does not store the first detergent. When the second detergent and the third detergent are selected to be dispensed, the power source 4001 moves along the second direction, thereby driving the connecting component 4002 to move, so that the connecting component 4002 drives the second actuator 2000 and the third actuator 3000 to move, and the second actuator 2000 moves to achieve the dispensing of the second detergent, and the third actuator 3000 moves to achieve the dispensing of the third detergent.

[0054] In order to adapt to the different actions of the power source 4001 when it moves in the first direction and the second direction, continue to combine Figures 4 to 7 As shown, in some embodiments, the connecting component 4002 includes an input component 4100, an intermediate component 4200, a first output component 4300 and a second output component 4400. The power source 4001 is connected to the input component 4100, and the power source 4001 can drive the input component 4100 to move. Since the power source 4001 can move along the first direction and the second direction, the action generated by the input component 4100 when the power source 4001 moves along the first direction is different from the action generated when the power source 4001 moves along the second direction. The input component 4100 is connected to the intermediate component 4200, and the input component 4100 can drive the intermediate component 4200 to move. The different actions generated by the input component 4100 when the power source 4001 moves in the opposite direction also cause the intermediate component 4200 to produce different actions, thereby correspondingly driving the first output component 4300 and the second output component 4400.

[0055] Specifically, when the power source 4001 moves along the first direction, the power source 4001 drives the input part 4100 to move, and the movement of the input part 4100 drives the intermediate part 4200 to move. At the same time, the input part 4100 drives the intermediate part 4200 to move to the first position, so that the intermediate part 4200 cooperates with the first output part 4300 and drives the first output part 4300 to move. The movement of the first output part 4300 drives the first actuator 1000 to move, thereby realizing the release of the first detergent. When the power source 4001 moves in the second direction, the power source 4001 drives the input member 4100 to move, which in turn drives the intermediate member 4200 to move. Simultaneously, the input member 4100 drives the intermediate member 4200 to move to the second position, causing the intermediate member 4200 to cooperate with the second output member 4400 and drive the second output member 4400 to move. The movement of the second output member 4400 thereby drives the second actuator 2000 and the third actuator 3000 to move. The second actuator 2000 moves to dispense the second detergent, and the third actuator 3000 moves to dispense the third detergent. It is understood that the intermediate member 4200 can reciprocate between a first position and a second position. The first position is the extreme position of the intermediate member 4200 when the power source 4001 moves in the first direction, and the second position is the extreme position of the intermediate member 4200 when the power source 4001 moves in the second direction. That is, the first and second positions are the extreme positions of the reciprocating movement of the intermediate member 4200.

[0056] Further, continue to combine Figures 4 to 7 As shown, in some embodiments, the connecting assembly 4002 includes an input gear 4100, an intermediate gear 4200, a first output gear 4300 and a second output gear 4400. The input gear 4100, the intermediate gear 4200, the first output gear 4300 and the second output gear 4400 are all configured to be rotatable. It can be understood that the input gear 4100 constitutes the input member 4100 mentioned above, the intermediate gear 4200 constitutes the intermediate member 4200 mentioned above, the first output gear 4300 constitutes the first output member 4300 mentioned above, and the second output gear 4400 constitutes the second output member 4400 mentioned above.

[0057] The power source 4001 is connected to the input gear 4100, and the power source 4001 can drive the input gear 4100 to rotate. Since the power source 4001 can move in a first direction and a second direction, the rotation direction of the input gear 4100 when the power source 4001 moves in the first direction is opposite to the rotation direction when the power source 4001 moves in the second direction, that is, the input gear 4100 produces different movements. The input gear 4100 is engaged with the intermediate gear 4200, and the input gear 4100 can drive the intermediate gear 4200 to rotate. Since the input gear 4100 has two opposite rotation directions, the intermediate gear 4200 also has two opposite rotation directions. In this way, the different movements of the input gear 4100 when the power source 4001 moves in opposite directions also cause the intermediate gear 4200 to produce different movements, thereby correspondingly driving the first output member 4300 and the second output member 4400.

[0058] Specifically, when the power source 4001 moves along the first direction, the power source 4001 drives the input gear 4100 to rotate, and the rotation of the input gear 4100 drives the intermediate gear 4200 to rotate. At the same time, the input gear 4100 drives the intermediate gear 4200 to move to the first position, so that the intermediate gear 4200 engages with the first output gear 4300 and drives the first output gear 4300 to rotate. The rotation of the first output gear 4300 drives the first actuator 1000 to move, thereby realizing the delivery of the first detergent. When the power source 4001 moves along the second direction, the power source 4001 drives the input gear 4100 to rotate, and the rotation of the input gear 4100 drives the intermediate gear 4200 to rotate. At the same time, the input gear 4100 drives the intermediate gear 4200 to move to the second position, so that the intermediate gear 4200 is engaged with the second output gear 4400 and drives the second output gear 4400 to rotate. The rotation of the second output gear 4400 drives the second actuator 2000 and the third actuator 3000 to move. The second actuator 2000 moves to realize the delivery of the second detergent, and the third actuator 3000 moves to realize the delivery of the third detergent.

[0059] There are various types of power source 4001. For example, power source 4001 can be a motor, which converts electrical energy into mechanical energy. Specifically, the motor can be a stepper motor, a servo motor, or the like. When power source 4001 is a motor, the motor's ability to move in both the first and second directions is achieved through rotation. Specifically, the motor's shaft can rotate in both the first and second directions. By configuring power source 4001 as a motor, controlling the movement of connection assembly 4002 is facilitated.

[0060] Combine Figures 5 to 8As shown, in some embodiments, the first actuator 1000 includes a pump body 1100, and the driving mechanism 4000 is suitable for driving the pump body 1100 to move, thereby causing the pump body 1100 to suck and discharge the first detergent. It is understood that the pump body 1100, also known as a pump, is a machine that can suck and discharge fluids. The types of pump bodies 1100 include but are not limited to peristaltic pumps, piston pumps, etc. In this embodiment, the first detergent is a liquid detergent. When the first detergent needs to be added, the driving mechanism 4000 drives the first actuator 1000 to move. The movement of the first actuator 1000 is specifically manifested as the driving mechanism 4000 driving the corresponding structure of the pump body 1100 to move (such as driving the rotating shaft of the pump body 1100 to rotate), so that the pump body 1100 sucks the first detergent from the first cavity 6100 and discharges the first detergent, thereby achieving the addition of the first detergent.

[0061] It is understandable that current dispensing devices have different dispensing methods to adapt to different similar washing appliances. As washing appliances are upgraded, the dispensing methods of dispensing devices also need to be improved to meet more needs. Therefore, the above-mentioned drive mechanism 4000 driving the pump body 1100 can be applied not only to the dispensing device of this application, but also to other types of dispensing devices. For example, in other embodiments, the dispensing device includes a drive mechanism 4000 and a first actuator 1000. The first actuator 1000 includes a pump body 1100. The drive mechanism 4000 is suitable for driving the rotating shaft of the pump body 1100 to rotate, so that the pump body 1100 sucks and discharges the first detergent.

[0062] Further, combined with Figure 8 As shown, in some embodiments, the driving mechanism 4000 includes a first output gear 4300, which is coaxially arranged with the rotating shaft of the pump body 1100. The driving mechanism 4000 is suitable for driving the rotating shaft of the pump body 1100 to rotate through the first output gear 4300, so that the pump body 1100 absorbs and discharges the first detergent.

[0063] Specifically, by coaxially aligning the first output gear 4300 with the rotating shaft of the pump body 1100 , the first output gear 4300 can drive the rotating shaft of the pump body 1100 to rotate coaxially, which is beneficial for saving space. Taking the driving mechanism 4000 including a power source 4001 and a connecting component 4002, and the connecting component 4002 including an input gear 4100, an intermediate gear 4200, a first output gear 4300 and a second output gear 4400 as an example, when the power source 4001 moves along the first direction, the power source 4001 drives the input gear 4100 to rotate, and the rotation of the input gear 4100 drives the intermediate gear 4200 to rotate. At the same time, the input gear 4100 drives the intermediate gear 4200 to move to the first position, so that the intermediate gear 4200 is engaged with the first output gear 4300 and drives the first output gear 4300 to rotate. The rotation of the first output gear 4300 drives the rotating shaft of the pump body 1100 to rotate, and the pump body 1100 sucks in the first detergent and discharges the first detergent, thereby realizing the delivery of the first detergent.

[0064] Combine Figure 9 、 Figure 10 、 Figure 11 and Figure 13 As shown, in some embodiments, the driving mechanism 4000 is adapted to drive the second actuator 2000 to move, so that the second actuator 2000 unlocks the cover 7100 of the dispensing device and opens the dispensing port 6210 of the dispensing device, allowing the second detergent to be dispensed from the dispensing port 6210. It is understood that the dispensing device is provided with a position (second cavity 6200) for storing the second detergent, and the position (second cavity 6200) is formed with the dispensing port 6210. The dispensing device is provided with a cover 7100 for opening and closing the dispensing port 6210. When the second detergent is placed in the position, the cover 7100 closes the dispensing port 6210, and the second detergent cannot be dispensed from the dispensing port 6210. When the cover 7100 opens the dispensing port 6210, the second detergent can leave the second cavity 6200 and be dispensed from the dispensing port 6210 (i.e., the second detergent is dispensed). When the cover 7100 is in a state of closing the delivery port 6210, it is locked. When the cover 7100 is unlocked, the cover 7100 can be opened by the elastic member to open the delivery port 6210. In this embodiment, the second detergent is a solid detergent. When the second detergent needs to be delivered, the driving mechanism 4000 drives the second actuator 2000 to move, causing the second actuator 2000 to unlock the cover 7100, thereby opening the delivery port 6210. The second detergent is then delivered from the delivery port 6210, e.g., under the action of gravity.

[0065] It is understandable that current dispensing devices have different dispensing methods to adapt to different similar washing appliances. As washing appliances are updated, the dispensing methods of dispensing devices also need to be improved to meet more needs. Therefore, the above-mentioned second actuator 2000 and drive mechanism 4000 cooperate to unlock the cover 7100 can be applied not only to the dispensing device in this application, but also to other types of dispensing devices. For example, in other embodiments, the dispensing device includes a drive mechanism 4000 and a second actuator 2000, and the drive mechanism 4000 is suitable for driving the second actuator 2000 to move, so that the second actuator 2000 unlocks the cover 7100 of the dispensing device and causes the cover 7100 to open the dispensing port 6210 of the dispensing device to allow the second detergent to be dispensed from the dispensing port 6210.

[0066] Combine Figures 9 to 13 As shown, in some embodiments, the second actuator 2000 includes a rotating shaft 2100 and a claw 2200 disposed on the rotating shaft 2100. The driving mechanism 4000 is adapted to be connected to the rotating shaft 2100 to drive the rotating shaft 2100 to rotate. The claw 2200 is adapted to rotate when the rotating shaft 2100 rotates to unlock the cover 7100. The movement of the second actuator 2000 is specifically manifested as the driving mechanism 4000 driving the second actuator 2000 to rotate. More specifically, the driving mechanism 4000 drives the rotating shaft 2100 to rotate, so that the rotating shaft 2100 drives the claw 2200 to rotate. The rotation of the claw 2200 can unlock the cover 7100, thereby enabling the second detergent to be dispensed. The arrangement of the rotating shaft 2100 and the claw 2200 can keep the claw 2200 away from the driving mechanism 4000, making the structural arrangement more convenient.

[0067] Combine Figure 14 、 Figure 15 and Figure 16 As shown, in some embodiments, the claw 2200 is sleeved on the rotating shaft 2100. The peripheral wall of the rotating shaft 2100 is provided with a locking protrusion 2110, and the claw 2200 is provided with a notch 2210. The locking protrusion 2110 is adapted to engage with the notch 2210 so that the rotating shaft 2100 can drive the claw 2200 to rotate. This arrangement reduces the complexity of the coordination between the rotating shaft 2100 and the claw 2200, thereby simplifying the structure. Specifically, the locking protrusion 2110 engages with the notch 2210. When the rotating shaft 2100 rotates, the locking protrusion 2110 abuts against the wall of the notch 2210 along the rotation direction of the rotating shaft 2100, thereby driving the claw 2200 to rotate.

[0068] Further, continue to combine Figure 14 and Figure 15As shown, in some embodiments, the claw 2200 is suitable for reciprocating along the rotating shaft 2100 between a third position and a fourth position; in the third position, the protrusion 2110 is engaged with the notch 2210; in the fourth position, the protrusion 2110 and the notch 2210 are separated so that the claw 2200 and the rotating shaft 2100 can rotate relative to each other.

[0069] The claw 2200 is movably matched with the rotating shaft 2100, and the claw 2200 can move to a third position and a fourth position along the rotating shaft 2100. The third position and the fourth position are the limit positions of the reciprocating movement of the claw 2200. When the claw 2200 is in the third position, the protrusion 2110 is engaged with the notch 2210. In this case, the rotating shaft 2100 can drive the claw 2200 to rotate. When the claw 2200 is in the fourth position, the protrusion 2110 is separated from the notch 2210. When the rotating shaft 2100 rotates, along the rotation direction of the rotating shaft 2100, the protrusion 2110 no longer abuts against the wall of the notch 2210. In this way, the rotating shaft 2100 can no longer drive the claw 2200 to rotate, that is, the rotating shaft 2100 and the claw 2200 can rotate relative to each other.

[0070] The drive mechanism 4000 is adapted to rotate the rotating shaft 2100 when the claw 2200 is in the third position. The claw 2200 is adapted to switch from the third position to the fourth position after unlocking the cover 7100. In other words, when the second detergent is dispensed, the claw 2200 is adapted to be in the third position. The drive mechanism 4000 then rotates the rotating shaft 2100, which in turn rotates the claw 2200, thereby unlocking the cover 7100. In this embodiment, the claw 2200 is suitable for switching from the third position to the fourth position after unlocking the cover body 7100, that is, after the rotating shaft 2100 drives the claw 2200 to rotate a certain angle, the claw 2200 unlocks the cover body 7100, the cover body 7100 opens the delivery port 6210, and the claw 2200 needs to switch from the third position to the fourth position. Subsequently, if the driving mechanism 4000 continues to control the rotation of the rotating shaft 2100, the rotating shaft 2100 can no longer drive the claw 2200 to rotate, so that the driving mechanism 4000 can continue to perform other actions without affecting the claw 2200.

[0071] The movement of the claw 2200 from the third position to the fourth position can be achieved by the first elastic member 5100, combined with Figures 10 to 13As shown, in some embodiments, the delivery device further includes a first elastic member 5100, which is adapted to generate a force on the claw 2200, thereby driving the claw 2200 to switch from the third position to the fourth position after the claw 2200 unlocks the cover 7100. That is, when the claw 2200 is in the third position, the first elastic member 5100 elastically deforms and accumulates elastic potential energy. At this time, the first elastic member 5100 generates a force on the claw 2200, which causes the claw 2200 to have a tendency to switch from the third position to the fourth position. When the driving mechanism 4000 drives the rotating shaft 2100 to rotate, the rotating shaft 2100 drives the claw 2200 to rotate, causing the claw 2200 to unlock the cover 7100. The cover 7100 opens the delivery port 6210 and separates from the claw 2200. At this time, the first elastic member 5100 releases the elastic potential energy, thereby switching the claw 2200 from the third position to the fourth position. Optionally, the first elastic member 5100 is sleeved on the rotating shaft 2100, which makes it easier to arrange the first elastic member 5100. It is understandable that the first elastic member 5100 can be a spring, a pull rope, etc., and the second elastic member 5200 and the third elastic member 5300 are also the same, and no further details are given.

[0072] Further, continue to combine Figures 10 to 13 As shown, in some embodiments, when the cover 7100 switches from the open state of the delivery port 6210 to the closed state of the delivery port 6210, it drives the claw 2200 to switch from the fourth position to the third position. It is understandable that the switch of the cover 7100 from the open state of the delivery port 6210 to the closed state of the delivery port 6210 can be achieved electrically or manually. For example, during the operation of the washing machine, the cover 7100 can switch from the closed state of the delivery port 6210 to the open state of the delivery port 6210. After the washing machine is finished, the user can re-place the second detergent and manually switch the cover 7100 to the closed state of the delivery port 6210, at which time the cover 7100 is re-engaged with the claw 2200. In order to dispense the second detergent for the next time, in this embodiment, when the cover 7100 is switched to the state of closing the dispensing port 6210, the cover 7100 drives the claw 2200 to switch from the fourth position to the third position, so that the locking protrusion 2110 is engaged with the notch 2210. Only in this way can the rotating shaft 2100 drive the claw 2200 to rotate when the second detergent is dispensed for the next time. Optionally, the cover 7100 is provided with a protrusion 7120, and the cover 7100 is suitable for pushing the claw 2200 through the protrusion 7120, so that the claw 2200 switches from the fourth position to the third position. The provision of the protrusion 7120 makes it easier for the cover 7100 to push the claw 2200.

[0073] Combine Figures 10 to 13As shown, in some embodiments, the claw 2200 is provided with a locking portion 2220, and the cover body 7100 has an abutting portion 7110. The locking portion 2220 is suitable for stopping the abutting portion 7110 in the direction of the cover body 7100 opening the delivery port 6210 so that the cover body 7100 is in a state of closing the delivery port 6210. The locking portion 2220 is suitable for separating from the abutting portion 7110 when the claw 2200 rotates so that the cover body 7100 is switched from the state of closing the delivery port 6210 to the state of opening the delivery port 6210.

[0074] When the cover body 7100 is in the state of closing the delivery port 6210, the locking portion 2220 stops the abutting portion 7110, and the second actuator 2000 locks the cover body 7100. The cover body 7100 cannot move in the direction of opening the delivery port 6210, so that the cover body 7100 cannot switch from the state of closing the delivery port 6210 to the state of opening the delivery port 6210, that is, the cover body 7100 remains in the state of closing the delivery port 6210. When the second detergent needs to be added, the driving mechanism 4000 controls the rotating shaft 2100 to rotate, and the rotating shaft 2100 drives the claw 2200 to rotate. The rotation of the claw 2200 separates the locking portion 2220 from the abutting portion 7110, that is, the locking portion 2220 no longer stops the abutting portion 7110 in the direction of the cover body 7100 opening the delivery port 6210, so that the cover body 7100 can bounce open under the action of the elastic member, thereby switching from the state of closing the delivery port 6210 to the state of opening the delivery port 6210.

[0075] Combine Figures 10 to 13 As shown, in some embodiments, the dispensing device further includes a second elastic member 5200, which is adapted to generate a force on the latching claw 2200 to generate an obstructive force on the latching claw 2200 when the latching claw 2200 rotates to open the cover 7100. Specifically, when the rotating shaft 2100 drives the latching claw 2200 to rotate to unlock the cover 7100, as the latching claw 2200 rotates, the second elastic member 5200 elastically deforms, thereby accumulating elastic potential energy and generating an obstructive force on the latching claw 2200. After the latching claw 2200 unlocks the cover 7100, the second elastic member 5200 can release the elastic potential energy, thereby driving the latching claw 2200 to return in a direction opposite to the rotation direction of unlocking the cover 7100, thereby facilitating the latching claw 2200 and the cover 7100 to cooperate to lock the cover 7100 when the cover 7100 recloses the dispensing port 6210.

[0076] For example, when the driving mechanism 4000 drives the rotating shaft 2100 to rotate, the rotating shaft 2100 drives the claw 2200 to rotate to unlock the cover body 7100. At the same time, the claw 2200 causes the second elastic member 5200 to elastically deform. After the cover body 7100 opens the delivery port 6210, the first elastic member 5100 releases elastic potential energy to drive the claw 2200 to move from the third position to the fourth position. The second elastic member 5200 releases elastic potential energy to drive the claw 2200 to reset in the opposite direction of the rotation direction of unlocking the cover body 7100.

[0077] Furthermore, in some embodiments, when the cover body 7100 switches from a state of opening the delivery port 6210 to a state of closing the delivery port 6210, the abutment portion 7110 of the cover body 7100 touches the locking portion 2220 of the claw 2200, so that the claw 2200 first rotates in the direction of unlocking the cover body 7100 and then rotates in the opposite direction to stop the abutment portion 7110 in the direction of opening the delivery port 6210 of the cover body 7100.

[0078] When the latch 2200 is in the unlocked position, the latch 2200 is in the unlocked position, and the latch 2200 is in the unlocked position, so that the latch 2200 can be unlocked.

[0079] Combine Figures 10 to 13 As shown, in some embodiments, the driving mechanism 4000 includes a second output gear 4400. The driving mechanism 4000 is suitable for driving the rotating shaft 2100 to rotate through the second output gear 4400. The second output gear 4400 is sleeved on the rotating shaft 2100 and is suitable for driving the rotating shaft 2100 to rotate when rotating. The second output gear 4400 is sleeved on the rotating shaft 2100, that is, the second output gear 4400 and the rotating shaft 2100 are coaxially arranged. In this way, the second output gear 4400 can drive the rotating shaft 2100 to rotate coaxially, which is conducive to saving space. Optionally, combined with Figures 9 and 10 As shown, the third actuator 3000 is disposed between the second output gear 4400 and the claw 2200 , thereby fully utilizing the space and making the structure of the delivery device more compact.

[0080] Taking the driving mechanism 4000 including the power source 4001 and the connecting component 4002, and the connecting component 4002 including the input gear 4100, the intermediate gear 4200, the first output gear 4300 and the second output gear 4400 as an example, when the power source 4001 moves along the second direction, the power source 4001 drives the input gear 4100 to rotate, and the rotation of the input gear 4100 drives the intermediate gear 4200 to rotate. At the same time, the input gear 4100 drives the intermediate gear 4200 to move to the second position, so that the intermediate gear 4200 is engaged with the second output gear 4400 and drives the second output gear 4400 to rotate. The rotation of the second output gear 4400 drives the rotating shaft 2100 to rotate, and the rotation of the rotating shaft 2100 drives the claw 2200 to rotate. The rotation of the claw 2200 realizes the unlocking of the cover body 7100, thereby realizing the delivery of the second detergent. It is understandable that when the claw 2200 unlocks the cover body 7100, the claw 2200 switches to the fourth position. When the second output gear 4400 rotates to drive the third actuator 3000 to move, it will also drive the rotating shaft 2100 to rotate, but the rotating shaft 2100 no longer drives the claw 2200 to rotate.

[0081] Combine Figure 5 、 Figure 6 、 Figure 7 、 Figure 9 、 Figure 10 、 Figure 17 and Figure 18 As shown, in some embodiments, the driving mechanism 4000 is adapted to drive the third actuator 3000 to move so as to disengage the third actuator 3000 from the communication port 6310 of the dispensing device and allow the third detergent to flow out of the communication port 6310. It is understood that the dispensing device is provided with a location (third cavity 6300) for storing the third detergent, which is provided with the communication port 6310. The third actuator 3000 is adapted to disengage from and block the communication port 6310. When the third detergent is placed in this location, the third actuator 3000 needs to block the communication port 6310, preventing the third detergent from leaving the third cavity 6300 and flowing out of the communication port 6310. When the third actuator 3000 is disengaged from the communication port 6310, the third detergent can flow out of the communication port 6310, thereby achieving the dispensing of the third detergent. In this embodiment, the third detergent is a liquid detergent such as a rinse aid. When the third detergent needs to be added, the driving mechanism 4000 drives the third actuator 3000 to move, so that the third actuator 3000 is separated from the connecting port 6310, and the third detergent flows out from the connecting port 6310, and then is added directly or indirectly.

[0082] It is understandable that current dispensing devices have different dispensing methods to adapt to different similar washing appliances. As washing appliances are upgraded, the dispensing methods of dispensing devices also need to be improved to meet more needs. Therefore, the above-mentioned third actuator 3000 and drive mechanism 4000 can be used not only in the dispensing device of this application, but also in other types of dispensing devices. For example, in other embodiments, the dispensing device includes a drive mechanism 4000 and a third actuator 3000, and the drive mechanism 4000 is suitable for driving the third actuator 3000 to move so that the third actuator 3000 is separated from the connecting port 6310 of the dispensing device and the third detergent flows out of the connecting port 6310.

[0083] Combine Figure 17 and Figure 8 As shown, in some embodiments, the third actuator 3000 is provided with a rack portion 3121, and the driving mechanism 4000 is adapted to engage with the rack portion 3121 to drive the movement of the third actuator 3000. The movement of the third actuator 3000 is specifically manifested by the driving mechanism 4000 driving the rack portion 3121, thereby causing the third actuator 3000 to move, thereby disengaging from the communication port 6310. The provision of the rack enables linear displacement of the third actuator 3000, more effectively disengaging from the communication port 6310.

[0084] Continue to combine Figure 17 and Figure 18 As shown, in some embodiments, the drive mechanism 4000 includes a second output gear 4400. The drive mechanism 4000 is adapted to drive the rack portion 3121 to move via the second output gear 4400. The second output gear 4400 is provided with a shifting tooth portion 4420. When the second output gear 4400 rotates, the shifting tooth portion 4420 is engaged with the rack portion 3121 to drive the third actuator 3000 to move. When the second output gear 4400 rotates, the shifting tooth portion 4420 rotates with it. Since the shifting tooth portion 4420 is engaged with the rack portion 3121, the rotation of the second output gear 4400 drives the rack portion 3121 to move. The movement of the rack portion 3121 can cause the third actuator 3000 to disengage from the communication port 6310.

[0085] Taking the driving mechanism 4000 including the power source 4001 and the connecting component 4002, and the connecting component 4002 including the input gear 4100, the intermediate gear 4200, the first output gear 4300 and the second output gear 4400 as an example, when the power source 4001 moves along the second direction, the power source 4001 drives the input gear 4100 to rotate, and the rotation of the input gear 4100 drives the intermediate gear 4200 to rotate. At the same time, the input gear 4100 drives the intermediate gear 4200 to move to the second position, so that the intermediate gear 4200 is engaged with the second output gear 4400 and drives the second output gear 4400 to rotate. The rotation of the second output gear 4400 drives the rack part 3121 to move through the gear shifting part 4420. The movement of the rack part 3121 causes the third actuator 3000 to disengage from the connecting port 6310, thereby realizing the delivery of the third detergent.

[0086] Combine Figure 17 and Figure 18 As shown, in some embodiments, the second output gear 4400 is provided with a gear portion 4410, and the driving mechanism 4000 further includes an input gear 4100. The input gear 4100 is adapted to drive the second output gear 4400 to rotate via the gear portion 4410. The gear portion 4410 and the shifting gear portion 4420 are arranged along the axial direction of the second output gear 4400. In this embodiment, the gear portion 4410 of the second output gear 4400 is configured to be in transmission connection (directly or indirectly) with the input gear 4100. If the gear portion 4410 of the second output gear 4400 also meshes with the rack portion 3121, this would not be conducive to reducing space usage. However, arranging the gear portion 4410 and the shifting gear portion 4420 along the axial direction of the second output gear 4400 can help reduce space usage.

[0087] Optionally, combined Figure 18 As shown, along the radial direction of the second output gear 4400, the maximum distance between the center of the second output gear 4400 and the gear portion 4410 is greater than the maximum distance between the center of the second output gear 4400 and the shifting gear portion 4420. With this arrangement, along the axial direction of the second output gear 4400, the rack portion 3121 and even the entire third actuator 3000 at least partially overlap with the second output gear 4400, thereby reducing space usage.

[0088] Combine Figure 17 and Figure 18As shown, in some embodiments, the tooth portion 4420 is suitable for separating from the rack portion 3121 after the third actuator 3000 is separated from the connecting port 6310, and the delivery device also includes a third elastic member 5300, which is suitable for generating force on the third actuator 3000 to drive the third actuator 3000 to move toward the connecting port 6310 to block the connecting port 6310 after the tooth portion 4420 and the rack portion 3121 are separated.

[0089] Specifically, the tooth shifting portion 4420 is not arranged along the entire circumference of the second output gear 4400, but is arranged at a certain position on the circumference of the second output gear 4400. In this way, when the second output gear 4400 rotates, the tooth shifting portion 4420 engages with the rack portion 3121 and drives the third actuator 3000 to disengage from the connecting port 6310. When the second output gear 4400 continues to rotate a certain angle, the tooth shifting portion 4420 separates from the rack portion 3121. In this embodiment, by providing a third elastic member 5300, the third elastic member 5300 generates a force on the third actuator 3000, that is, when the second output gear 4400 rotates and the tooth shift portion 4420 engages with the rack portion 3121, thereby driving the third actuator 3000 to disengage from the connecting port 6310, the third elastic member 5300 undergoes elastic deformation and accumulates elastic potential energy and generates a force on the third actuator 3000. When the tooth shift portion 4420 is separated from the rack portion 3121, the third elastic member 5300 releases the elastic potential energy, thereby driving the third actuator 3000 to move toward the connecting port 6310 and block the connecting port 6310. In this way, when the driving mechanism 4000 drives the third actuator 3000, the connecting port 6310 can be blocked without changing the direction of movement, which is more conducive to the control of the driving mechanism 4000.

[0090] Optionally, in some embodiments, the tooth shifting portion 4420 is adapted to alternately engage and disengage with the rack portion 3121 when the second output gear 4400 rotates, thereby enabling multiple dosing of the third detergent. For example, when the second output gear 4400 rotates, the tooth shifting portion 4420 sequentially engages, disengages, engages, and disengages with the rack portion 3121 in four steps: the first step disengages the third actuator 3000 from the communication port 6310; the second step blocks the communication port 6310; the third step disengages the third actuator 3000 from the communication port 6310; and the fourth step blocks the communication port 6310, thereby enabling two dosings of the third detergent.

[0091] Combine Figure 17As shown, in some embodiments, the third actuator 3000 includes a flexible sealing plug 3200. The third actuator 3000 is adapted to be separated from the communication port 6310 and to seal the communication port 6310 through the sealing plug 3200. Specifically, the flexible sealing plug 3200 is elastically deformable. For example, the sealing plug 3200 is made of a material such as silicone or rubber. With this configuration, when the third actuator 3000 seals the communication port 6310, the sealing plug 3200 contacts and seals the communication port 6310, causing the sealing plug 3200 to deform, thereby better sealing the communication port 6310.

[0092] Optionally, the third actuator 3000 includes a frame member 3100 and a sealing plug 3200, which are sealingly connected to the frame member 3100. The frame member 3100 is provided with a rack portion 3121. It is understood that the frame member 3100 serves as a supporting framework for the sealing plug 3200 and is designed to have high structural strength. Through the provision of the frame member 3100, the frame member 3100 can drive the sealing plug 3200 to separate from the communication port 6310 and block the communication port 6310. When blocking the communication port 6310, the frame member 3100 can squeeze the sealing plug 3200 to achieve a better sealing effect.

[0093] Further, combined with Figure 17 and Figure 18 As shown, in some embodiments, the framework member 3100 includes a support rod 3110 and a transmission rod 3120. The support rod 3110 and the transmission rod 3120 are separate components and are interconnected. The sealing plug 3200 is provided on the support rod 3110, and the transmission rod 3120 is provided with a rack portion 3121. The support rod 3110 and the transmission rod 3120 are separate components, that is, the support rod 3110 and the transmission rod 3120 constitute independent components and are then connected together by a connection method. The provision of separate support rods 3110 and transmission rods 3120 facilitates the manufacture of the framework member 3100, reduces the manufacturing difficulty, and facilitates the structural arrangement. The support rod 3110 and the transmission rod 3120 can be connected in a variety of ways, such as screws, plug-in connections, snap-on connections, and other methods. In this embodiment, the support rod 3110 and the transmission rod 3120 are plug-in connections, which is convenient and quick.

[0094] The second aspect of the present application discloses a washing machine, including but not limited to a dishwasher, a washing machine, etc., which includes the dispensing device of the above-mentioned embodiment. In this embodiment, a driving mechanism 4000 is provided, and the driving mechanism 4000 is configured to drive the first actuator 1000, the second actuator 2000, and the third actuator 3000. In this way, the dispensing of multiple types of detergents can be controlled by the same set of driving mechanisms 4000. Compared with the dispensing devices in the related art, the number of driving mechanisms 4000 is greatly reduced, which is conducive to reducing the cost of the dispensing device and reducing the size of the dispensing device. It can be understood that the dispensing device of the washing machine of this embodiment adopts the technical solution of the above-mentioned embodiment, and therefore has at least the beneficial effects brought about by the technical solution of the above-mentioned embodiment, which will not be repeated here.

[0095] The above description is only a preferred embodiment of the present application and does not limit the patent scope of the present application. All equivalent structural transformations made based on the contents of the present application specification and drawings, or direct / indirect application in other related technical fields, are included in the patent protection scope of the present application.
