[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.

[0042] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). 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, Figures 1 to 9 as well as Figure 11 、 Figure 12 As shown, in some embodiments, the dispensing device includes a main body 1000 and an actuator 2000, and the main body 1000 is provided with a dispensing chamber 1200, a first connecting hole 1010 and a second connecting hole 1020, the first connecting hole 1010 is connected to the dispensing chamber 1200, and the second connecting hole 1020 is connected to the dispensing chamber 1200, and the detergent stored in the dispensing device can enter the dispensing chamber 1200 through the first connecting hole 1010, and the detergent entering the dispensing chamber 1200 can flow out through the second connecting hole 1020 and be dispensed into the washing chamber of the washing appliance.

[0046] The actuator 2000 must cooperate with the first connecting hole 1010 and the second connecting hole 1020 to enable detergent dispensing. The actuator 2000 is configured to be movable, allowing it to block the second connecting hole 1020 when disengaged from the first connecting hole 1010, and to disengage from the second connecting hole 1020 when blocking the first connecting hole 1010. Blocking means forming a seal that prevents detergent from passing through, while disengaging means opening the seal so that detergent can pass through. When detergent is not needed, the actuator 2000 blocks the first connecting hole 1010 and disengages from the second connecting hole 1020, preventing detergent stored in the dispensing device from passing through the first connecting hole 1010 and entering the dispensing chamber 1200. When detergent needs to be added, the actuator 2000 disengages from the first connecting hole 1010 and blocks the second connecting hole 1020. The detergent stored in the dosing device enters the dosing chamber 1200 through the first connecting hole 1010. Since the actuator 2000 blocks the second connecting hole 1020, the detergent that enters the dosing chamber 1200 can remain in the dosing chamber 1200. Then the actuator 2000 is switched to block the first connecting hole 1010 and disengage from the second connecting hole 1020. The detergent stored in the dosing device can no longer enter the dosing chamber 1200 through the first connecting hole 1010, and the detergent that has entered the dosing chamber 1200 flows out through the second connecting hole 1020 and is added to the washing chamber. The process of detergent flowing out from the second connecting hole 1020 to being added to the washing chamber can be directly entering the washing chamber or indirectly entering the washing chamber, which is not limited in this embodiment. The flow of detergent means that the detergent is liquid detergent. The main function of the detergent is to clean and remove dirt, and it can also be used as an auxiliary for cleaning and removing dirt. Of course, detergents with other functions can also be used, such as detergents that are rinse agents.

[0047] It is worth noting that when detergent needs to be added, the actuator 2000 switches from the state of blocking the first communicating hole 1010 and disengaging from the second communicating hole 1020 to the state of disengaging from the first communicating hole 1010 and blocking the second communicating hole 1020, so that the detergent stored in the dispensing device enters the dispensing chamber 1200 through the first communicating hole 1010. There are some problems here, that is, when the actuator 2000 is disengaged from the first communicating hole 1010 but has not yet blocked the second communicating hole 1020, the first communicating hole 1010 is not closed. 10 and the second connecting hole 1020 are in the open state at the same time, so that the detergent entering the delivery chamber 1200 will flow out through the second connecting hole 1020 and be delivered into the washing chamber. That is to say, when the actuator 2000 disengages from the first connecting hole 1010 until the second connecting hole 1020 is blocked, there is a situation that part of the detergent entering the delivery chamber 1200 leaks into the washing chamber, and finally the detergent in the delivery chamber 1200 is delivered into the washing chamber, which will cause the detergent delivery amount to be inaccurate and affect the washing effect.

[0048] To this end, in this embodiment, the actuator 2000 is designed to be inserted into the first communicating hole 1010 along the second direction to block the first communicating hole 1010, and to be pulled out of the first communicating hole 1010 along the first direction to detach from the first communicating hole 1010. The first direction is opposite to the second direction, and in the process of the actuator 2000 detaching from the first communicating hole 1010, the gap 1014 formed between the actuator 2000 and the outlet end 1013 of the first communicating hole 1010 gradually increases. As the gap 1014 gradually increases, the flow rate of detergent entering the delivery chamber 1200 through the gap 1014 gradually increases, that is, when the actuator 2000 just starts to detach from the first communicating hole 1010 but has not yet When the second connecting hole 1020 is blocked (the first connecting hole 1010 and the second connecting hole 1020 are both in a connected state), only a small amount of detergent enters the delivery chamber 1200. Until the actuator 2000 blocks the second connecting hole 1020, the gap 1014 between the actuator 2000 and the outlet end 1013 of the first connecting hole 1010 is the largest, and the flow rate of detergent entering the delivery chamber 1200 through the gap 1014 is the largest. Through such a setting, the detergent entering the delivery chamber 1200 when the actuator 2000 just begins to separate from the first connecting hole 1010 is avoided as much as possible from leaking into the washing chamber through the second connecting hole 1020, thereby improving the accuracy of detergent delivery as much as possible.

[0049] Combine Figures 4 to 9 As shown, in some embodiments, the actuator 2000 includes a first sealing portion 2210. When the actuator 2000 is inserted into the first connecting hole 1010, the first sealing portion 2210 is also inserted into the first connecting hole 1010. When the actuator 2000 is pulled out of the first connecting hole 1010, the first sealing portion 2210 is also pulled out of the first connecting hole 1010. In this embodiment, the first sealing portion 2210 is designed to be tapered along the second direction, and a gap 1014 is formed between the first sealing portion 2210 and the outlet end 1013 of the first connecting hole 1010 during the process of the actuator 2000 being separated from the first connecting hole 1010. The gradual increase of the gap 1014 is facilitated by the tapered first sealing portion 2210. That is, during the process of the actuator 2000 being pulled out of the first communicating hole 1010, since the outlet end 1013 of the first communicating hole 1010 is relatively stationary and the first sealing portion 2210 is gradually contracted along the second direction, as the actuator 2000 is pulled out of the first communicating hole 1010 (along the first direction), the gap 1014 formed between the outlet end 1013 of the first communicating hole 1010 and the first sealing portion 2210 can gradually increase.

[0050] Combine Figures 4 to 9As shown, in some embodiments, the first communication hole 1010 includes a first hole segment 1011, which is gradually expanded along the first direction. The first sealing portion 2210 is adapted to abut against the first hole segment 1011 when the actuator 2000 blocks the first communication hole 1010. The first sealing portion 2210 is gradually contracted along the second direction, while the first hole segment 1011 is gradually expanded along the first direction. Thus, when the actuator 2000 is inserted into the first communication hole 1010 along the second direction, the first hole segment 1011 abuts against the first sealing portion 2210, thereby acting as a stop and positioning for the insertion of the actuator 2000 and simultaneously forming a seal.

[0051] Combine Figures 4 to 9 As shown, in some embodiments, the first connecting hole 1010 also includes a second hole segment 1012, and the second hole segment 1012 is located downstream of the first hole segment 1011. The so-called downstream means that when the detergent passes through the first connecting hole 1010, it first flows through the first hole segment 1011 and then flows through the second hole segment 1012. In this embodiment, the second hole segment 1012 is designed to be straight, that is, the second hole segment 1012 is a straight segment. The actuator 2000 also includes a second sealing portion 2220. When the actuator 2000 blocks the first connecting hole 1010, the second sealing portion 2220 is interference fit with the second hole segment 1012 (for example, the second sealing portion 2220 is set with equal diameters), so that the second sealing portion 2220 forms a seal with the second hole segment 1012. It is understood that the first hole section 1011 is configured to expand gradually while the second hole section 1012 is configured to be straight. Thus, the seal formed between the first hole section 1011 and the first sealing portion 2210, and the seal formed between the second hole section 1012 and the second sealing portion 2220, are in different sealing directions. This facilitates improving the sealing effect when the actuator 2000 blocks the first communicating hole 1010. Furthermore, during the process of the actuator 2000 being separated from the first communicating hole 1010, the second sealing portion 2220 can maintain its seal with the second hole section 1012 before the actuator 2000 moves in the first direction a distance corresponding to the length of the second hole section 1012. This minimizes the risk of detergent entering the dispensing chamber 1200 immediately after the actuator 2000 is separated from the first communicating hole 1010, further facilitating improved detergent dispensing accuracy.

[0052] In some embodiments of the present application, Figures 4 to 9As shown, in some embodiments, the actuator 2000 is configured to reciprocate to achieve coordination with the first connecting hole 1010 and the second connecting hole 1020, simplifying control. Specifically, the actuator 2000 can move in a first direction and a second direction, the first direction being opposite to the second direction, thereby achieving reciprocating movement. When the actuator 2000 moves in the first direction, it disengages from the first connecting hole 1010 and blocks the second connecting hole 1020. When the actuator 2000 moves in the first direction, there is a state where it disengages from the first connecting hole 1010 but does not yet block the second connecting hole 1020. Through the improvements of the present application, in this state, detergent is minimized from entering the dispensing chamber 1200 through the first connecting hole 1010 and leaking through the second connecting hole 1020. When the actuator 2000 moves in the second direction, it blocks the first connecting hole 1010 and disengages from the second connecting hole 1020.

[0053] For example, the actuator 2000 includes a sealing plug 2200, which is flexible. For example, the sealing plug 2200 is made of materials such as silicone and rubber. The sealing plug 2200 is provided with a first sealing part 2210, a second sealing part 2220 and a third sealing part 2230. The sealing plug 2200 is passed through the second connecting hole 1020, and the first sealing part 2210, the second sealing part 2220 and the third sealing part 2230 are provided between the first connecting hole 1010 and the second connecting hole 1020. When the actuator 2000 moves along the first direction, the first sealing part 2210, the second sealing part 2220 and the third sealing part 2230 follow the movement, so that the first sealing part 2210 and the second sealing part 2220 are separated from the first communicating hole 1010, and the third sealing part 2230 blocks the second communicating hole 1020. When the actuator 2000 moves along the first direction, there is a state in which the first sealing part 2210 and the second sealing part 2220 are separated from the first communicating hole 1010 but the third sealing part 2230 has not yet blocked the second communicating hole 1020; when the actuator 2000 moves along the second direction, the first sealing part 2210, the second sealing part 2220 and the third sealing part 2230 follow the movement, so that the first sealing part 2210 and the second sealing part 2220 block the first communicating hole 1010, and the third sealing part 2230 is separated from the second communicating hole 1020.

[0054] Combine Figure 8 and Figure 9As shown, in some embodiments, the length of the portion of the actuator 2000 suitable for insertion into the first communicating hole 1010 is L1. The actuator 2000 moves a distance L2 from blocking the first communicating hole 1010 to disengage from the first communicating hole 1010 and block the second communicating hole 1020, satisfying L1>L2. By having L1 greater than L2, when the actuator 2000 blocks the second communicating hole 1020, the actuator 2000 disengages from the first communicating hole 1010 but does not completely leave the first communicating hole 1010. This facilitates smooth insertion of the actuator 2000 into the first communicating hole 1010 when moving in the second direction to block the first communicating hole 1010, reducing the occurrence of sticking. This arrangement also ensures that the first communicating hole 1010 is not completely exposed when the actuator 2000 moves to block the second communicating hole 1020, further facilitating improved detergent dispensing accuracy.

[0055] Combine Figures 4 to 7 As shown, in some embodiments, the main body 1000 is provided with a storage chamber 1100, and the storage chamber 1100 is used to store detergent. The actuator 2000 is used to control the detergent to enter the delivery chamber 1200 from the storage chamber 1100. Since the volume of the delivery chamber 1200 is constant, the amount of detergent entering the delivery chamber 1200 each time is constant, that is, the amount of detergent delivered to the washing chamber each time is constant, thereby avoiding the difference in the amount of detergent delivered during each delivery process as much as possible.

[0056] Specifically, when detergent is not needed, the actuator 2000 blocks the first communicating hole 1010 and disengages from the second communicating hole 1020, preventing the detergent in the storage chamber 1100 from passing through the first communicating hole 1010 and entering the dispensing chamber 1200. When detergent needs to be dispensed, the actuator 2000 disengages from the first communicating hole 1010 and blocks the second communicating hole 1020, allowing the detergent in the storage chamber 1100 to enter the dispensing chamber 1200 through the first communicating hole 1010. The actuator 2000 is then controlled to switch to blocking the first communicating hole 1010 and disengaging from the second communicating hole 1020. At this point, the detergent in the storage chamber 1100 cannot continue to pass through the first communicating hole 1010 and enter the dispensing chamber 1200. The detergent that has already entered the dispensing chamber 1200 flows out through the second communicating hole 1020 and is dispensed into the washing chamber.

[0057] In some embodiments, the dispensing device is suitable for being installed on the door body of the washing appliance. The door body has a closed state and an open state. The door body is arranged vertically when it is closed, and is arranged horizontally when it is open. When the door body is in the closed state, the door body closes the washing chamber, and when the door body is in the open state, the door body opens the washing chamber. When it is necessary to load the target object into the washing chamber, the door body opens the washing chamber and is in the open state. At this time, the door body is arranged horizontally. When it is necessary to wash the target object, the door body closes the washing chamber and is in the closed state. At this time, the door body is arranged vertically. The dispensing device is installed on the door body, specifically on the inner side of the door body.

[0058] Combine Figures 4 to 7 as well as Figures 11 to 14 As shown, the storage chamber 1100 includes a first storage chamber 1110 and a second storage chamber 1120, and the first storage chamber 1110 is connected to the second storage chamber 1120. When the door body is in an open state, the detergent enters the second storage chamber 1120 from the first storage chamber 1110. It can be understood that as long as there is detergent entering the second storage chamber 1120 when the door body is in an open state, regardless of the amount of detergent entering the second storage chamber 1120, it can be regarded as the detergent entering the second storage chamber 1120 from the first storage chamber 1110, and when the door body is switched from an open state to a closed state, detergent is retained in the first storage chamber 1110 and the second storage chamber 1120 respectively, and the detergent in the first storage chamber 1110 is isolated from the detergent in the second storage chamber 1120. That is to say, when the door body is in an open state, a portion of the detergent enters the second storage chamber 1120 from the first storage chamber 1110, and the remaining portion of the detergent remains in the first storage chamber 1110. When the door body is switched from an open state to a closed state, the aforementioned portion of the detergent remains in the second storage chamber 1120, and the aforementioned remaining portion of the detergent remains in the first storage chamber 1110. The detergent in the first storage chamber 1110 is isolated from the detergent in the second storage chamber 1120. It can be understood that the isolation of the detergent in the first storage chamber 1110 from the detergent in the second storage chamber 1120 means that in this state, the detergent in the second storage chamber 1120 cannot enter the first storage chamber 1110, and the detergent in the first storage chamber 1110 cannot enter the second storage chamber 1120.

[0059] In this embodiment, when the door is closed, the actuator 2000 controls the detergent in the second storage chamber 1120 to enter the dispensing chamber 1200. During a single door opening and closing process, detergent remains in both the first storage chamber 1110 and the second storage chamber 1120. When detergent is no longer needed, the actuator 2000 blocks the first connecting hole 1010 and disengages from the second connecting hole 1020. If the actuator 2000 does not tightly seal the first connecting hole 1010, detergent from the second storage chamber 1120 may leak into the dispensing chamber 1200. Since the actuator 2000 is disengaged from the second connecting hole 1020, the detergent leaked into the dispensing chamber 1200 flows out through the second connecting hole 1020 and ultimately enters the washing chamber. Since the detergent in the first storage chamber 1110 does not enter the second storage chamber 1120 and leak, the amount of detergent leakage can be reduced. In particular, the amount of detergent stored in the second storage chamber 1120 can be designed to be the amount required in a single washing process. Even if all the detergent in the second storage chamber 1120 leaks out and leaks into the washing chamber during a single washing process, although it is not in the appropriate washing stage, it can still reduce the impact on the washing process compared to the related art where all the detergent leaks into the washing chamber.

[0060] Combine Figure 11 、 Figure 13 and Figure 14 As shown, in some embodiments, a third connecting hole 1030 is provided between the first storage chamber 1110 and the second storage chamber 1120, and the third connecting hole 1030 connects the first storage chamber 1110 and the second storage chamber 1120. When the door body is in an open state, the detergent is suitable for entering the second storage chamber 1120 from the first storage chamber 1110 through the third connecting hole 1030. The first storage chamber 1110 is connected to the second storage chamber 1120 through the third connecting hole 1030. When the door body is in the open state, the dispensing device is also arranged horizontally. A part of the detergent enters the second storage chamber 1120 from the first storage chamber 1110 through the third connecting hole 1030, and the remaining part of the detergent remains in the first storage chamber 1110. When the door body is switched from an open state to a closed state, the dispensing device is changed from a horizontal setting to a vertical setting. The aforementioned part of the detergent remains in the second storage chamber 1120 and cannot enter the first storage chamber 1110 through the third connecting hole 1030. The aforementioned remaining part of the detergent remains in the first storage chamber 1110 and cannot enter the second storage chamber 1120 through the third connecting hole 1030.

[0061] Optionally, in some embodiments, when the door is open, the highest point of the detergent liquid level in the first storage chamber 1110 is higher than both the lowest points of the third connecting hole 1030 and the lowest points of the second storage chamber 1120, allowing detergent to flow from the first storage chamber 1110 through the third connecting hole 1030 into the second storage chamber 1120. In this state, since the detergent liquid level in the first storage chamber 1110 is higher, the detergent can flow through the third connecting hole 1030 into the second storage chamber 1120 under the action of gravity until the detergent liquid level in the second storage chamber 1120 reaches the same level as that in the first storage chamber 1110. Detergent is present in both the second storage chamber 1120 and the first storage chamber 1110. This configuration facilitates the flow of detergent from the first storage chamber 1110 through the third connecting hole 1030 into the second storage chamber 1120 when the door is open.

[0062] Optionally, in some embodiments, when the door is closed, the highest point of the detergent liquid level in the first storage chamber 1110 is lower than the lowest point of the third connecting hole 1030, and the highest point of the detergent liquid level in the second storage chamber 1120 is lower than the lowest point of the third connecting hole 1030. In this state, because the lowest point of the third connecting hole 1030 is higher than the detergent liquid level in the second storage chamber 1120 and higher than the detergent liquid level in the first storage chamber 1110, the detergent in the second storage chamber 1120 cannot enter the first storage chamber 1110 through the third connecting hole 1030, and the detergent in the first storage chamber 1110 cannot enter the second storage chamber 1120 through the third connecting hole 1030. In this way, the detergent in the second storage chamber 1120 is isolated from the detergent in the first storage chamber 1110.

[0063] Taking the door opening and closing process as an example, when the door is open, since the detergent level in the first storage chamber 1110 is higher, the detergent can flow through the third connecting hole 1030 under the action of gravity and enter the second storage chamber 1120. This happens until the detergent level in the second storage chamber 1120 reaches the same level as the detergent level in the first storage chamber 1110. Detergent is present in both the second storage chamber 1120 and the first storage chamber 1110. When the door switches from open to closed, the detergent in the second storage chamber 1120 falls under the action of gravity until the level is below the lowest point of the third connecting hole 1030. Similarly, the detergent in the first storage chamber 1110 falls under the action of gravity until the level is below the lowest point of the third connecting hole 1030. At this point, detergent remains in both the second storage chamber 1120 and the first storage chamber 1110.

[0064] Combine Figure 11 、 Figure 13 and Figure 14As shown, in some embodiments, a partition 1370 is provided between the first storage chamber 1110 and the second storage chamber 1120. The partition 1370 is adapted to separate the detergent in the first storage chamber 1110 from the detergent in the second storage chamber 1120 when the door is closed. The provision of the partition 1370 facilitates the isolation of the detergent in the second storage chamber 1120 from the detergent in the first storage chamber 1110. Optionally, the partition 1370 is adapted to extend vertically when the door is closed. The vertical extension of the partition 1370 facilitates the side-by-side arrangement of the second storage chamber 1120 and the first storage chamber 1110, thereby maximizing space utilization.

[0065] Combine Figure 10 and Figure 11 As shown, the orientation is based on the door being in the closed state, and the user stands in front of the washing appliance to control the door to open and close. The main body 1000 has a front wall 1310, a rear wall 1320, a left side wall 1330, a right side wall 1340, a top wall 1350, and a bottom wall 1360. The front wall 1310, the rear wall 1320, the left side wall 1330, the right side wall 1340, the top wall 1350, and the bottom wall 1360 collectively enclose a certain space. A partition 1370 is disposed between the front wall 1310 and the rear wall 1320, and the top of the partition 1370 and the top wall 1350 are alternately arranged to form a third communicating hole 1030. The bottom of the partition 1370 and the bottom wall 1360 are connected, thereby dividing the first storage chamber 1110 and the second storage chamber 1120. When the door body is in the open state, the second storage chamber 1120 and the first storage chamber 1110 are arranged horizontally. At this time, the detergent can enter the second storage chamber 1120 from the first storage chamber 1110 through the third connecting hole 1030. When the door body is in the closed state, the second storage chamber 1120 and the first storage chamber 1110 are arranged vertically. Through the isolation of the partition 1370, the detergent in the second storage chamber 1120 cannot enter the first storage chamber 1110, and the detergent in the first storage chamber 1110 cannot enter the second storage chamber 1120.

[0066] Combine Figure 14 As shown, in some embodiments, the volume of the first storage chamber 1110 is greater than the volume of the second storage chamber 1120. For example, the volume of the first storage chamber 1110 is two times, three times, four times or more than the volume of the second storage chamber 1120. By such a setting, the frequency of replenishing detergent can be reduced.

[0067] For example, a dishwasher is used as a washing machine, and the detergent is rinse aid. When the dishwasher is used for the first time, the door is controlled to open, dishes (target objects) are loaded into the washing chamber, and rinse aid (detergent) is injected into the first storage chamber 1110. A portion of the rinse aid flows from the first storage chamber 1110 into the second storage chamber 1120. The door is then controlled to close, leaving rinse aid in both the second storage chamber 1120 and the first storage chamber 1110. During the wash cycle, the rinse aid in the second storage chamber 1120 flows into the dispensing chamber 1200 and is subsequently dispensed into the washing chamber. After the wash cycle is complete, the door is controlled to open, the dishes (target objects) are removed, and the door is closed. During the process of opening the door until the door closes, a portion of the rinse aid flows from the first storage chamber 1110 into the second storage chamber 1120, leaving rinse aid in both the second storage chamber 1120 and the first storage chamber 1110.

[0068] When the dishwasher is used for the second time, the door is controlled to open, tableware (target objects) are loaded into the washing chamber, and then the door is controlled to close. At this time, rinse agent is retained in the second storage chamber 1120 and the first storage chamber 1110 respectively. During the washing process, the rinse agent in the second storage chamber 1120 is controlled to enter the delivery chamber 1200 and then be delivered into the washing chamber. After washing is completed, the door is controlled to open, the tableware (target objects) are taken out and then the door is closed. In the process of opening the door after washing and closing the door, a part of the rinse agent enters the second storage chamber 1110 from the first storage chamber 1120, so that rinse agent is retained in the second storage chamber 1120 and the first storage chamber 1110 respectively.

[0069] Similarly, the sizes of the first storage chamber 1110 and the second storage chamber 1120 can be designed according to actual conditions. There is no need to refill the first storage chamber 1110 with rinse aid every time the dishwasher is used. Instead, rinse aid can be refilled after the dishwasher has been used multiple times.

[0070] It is understood that, precisely because the volume of the first storage chamber 1110 is greater than the volume of the second storage chamber 1120, when the dishwasher is used multiple times, the amount of detergent entering the second storage chamber 1120 each time the dishwasher is used remains constant until the amount of detergent in the first storage chamber 1110 decreases to less than a certain level. This ensures that the detergent is dispensed at a consistent rate during the first several uses of the dishwasher. It is also understood that a detection device can be provided to promptly remind the user to replenish the detergent in the first storage chamber 1110. For example, the amount of detergent entering the second storage chamber 1120 during the first 20 openings and closings of the door is consistent, but the amount of detergent entering the second storage chamber 1120 during the 21st opening and closing of the door decreases. This ensures that the detergent dispensing rate is consistent during the first 20 uses, and an alarm can be issued during the 21st opening and closing to prompt the user to replenish the detergent.

[0071] Combine Figure 11 and Figure 12 As shown, in some embodiments, the volume of the second storage chamber 1120 is larger than the volume of the delivery chamber 1200. For example, the volume of the second storage chamber 1120 is two times, three times, four times or more than the volume of the delivery chamber 1200, thereby ensuring that multiple doses of detergent can be achieved in a single washing process.

[0072] Combine Figure 1 and Figure 2 As shown, in some embodiments, the main body 1000 is further provided with a feeding port 1040, which is in communication with the first storage chamber 1110, so that detergent can be added to the first storage chamber 1110 through the feeding port 1040. When detergent needs to be added, the door is in an open state, and the dispensing device is arranged generally horizontally. The user can add detergent to the first storage chamber 1110 through the feeding port 1040. After the detergent enters the first storage chamber 1110, a portion of the detergent enters the second storage chamber 1120. It will be understood that the main body 1000 is generally provided with a cover 1380, which is used to close and open the feeding port 1040.

[0073] Combine Figures 3 to 7 as well as Figures 15 to 19 As shown, in some embodiments, the dispensing device further includes a driving mechanism 3000, which is adapted to drive the actuator 2000 to move in a first direction, so that the actuator 2000 disengages from the first communicating hole 1010 and blocks the second communicating hole 1020. The actuator 2000 disengages from the first communicating hole 1010 and blocks the second communicating hole 1020 via the driving mechanism 3000. The driving mechanism 3000 is a component capable of outputting power. The provision of the driving mechanism 3000 paves the way for automatic detergent dispensing.

[0074] Optionally, combined Figures 15 to 19 As shown, in some embodiments, the driving mechanism 3000 includes an output gear 3200, the output gear 3200 is provided with a tooth portion 3210, and the actuator 2000 is provided with a rack portion 2100. The output gear 3200 is suitable for driving the actuator 2000 to move along the first direction through the engagement of the tooth portion 3210 and the rack portion 2100 when rotating.

[0075] The drive mechanism 3000 outputs power through the output gear 3200. It is understood that the output gear 3200 outputs power in the form of rotation. For example, the drive mechanism 3000 includes a power source 3100. The power source 3100 can be of various types, such as a motor that converts electrical energy into mechanical energy. The motor can be a stepper motor, a servo motor, etc. The power source 3100 directly or indirectly drives the output gear 3200 to rotate. When the output gear 3200 rotates, the shifting gear portion 3210 rotates accordingly. The shifting gear portion 3210 engages with the rack portion 2100, so that the rotation of the output gear 3200 drives the rack portion 2100 to linearly displace (move in the first direction), thereby driving the actuator 2000 to disengage from the first connecting hole 1010 and block the second connecting hole 1020.

[0076] Combine Figures 15 to 19 As shown, in some embodiments, the tooth-shifting portion 3210 is suitable for separating from the rack portion 2100 after the actuator 2000 is disengaged from the first connecting hole 1010 and blocks the second connecting hole 1020, and the delivery device also includes an elastic member 4000, which is suitable for generating a force on the actuator 2000 to drive the actuator 2000 to move along the second direction to block the first connecting hole 1010 and disengage from the second connecting hole 1020 after the tooth-shifting portion 3210 is separated from the rack portion 2100.

[0077] Specifically, the tooth-shifting portion 3210 is not arranged along the circumference of the entire output gear 3200, but is arranged at a certain position on the circumference of the output gear 3200. In this way, when the output gear 3200 rotates, the tooth-shifting portion 3210 engages with the rack portion 2100 and drives the actuator 2000 to disengage from the first connecting hole 1010 and block the second connecting hole 1020. When the output gear 3200 continues to rotate a certain angle, the tooth-shifting portion 3210 separates from the rack portion 2100. In this embodiment, by providing an elastic member 4000, the elastic member 4000 generates a force on the actuator 2000. When the output gear 3200 rotates and the tooth portion 3210 engages with the rack portion 2100, thereby driving the actuator 2000 to move in the first direction and disengage from the first connecting hole 1010 and block the second connecting hole 1020, the detergent enters the delivery chamber 1200 from the storage chamber 1100 through the first connecting hole 1010, and the elastic member 4000 undergoes elastic deformation to accumulate elastic potential energy and generate ... When the rotation continues to a certain angle, the tooth portion 3210 separates from the rack portion 2100, and the elastic member 4000 releases elastic potential energy to drive the actuator 2000 to move in the second direction to block the first connecting hole 1010 and disengage from the second connecting hole 1020. The detergent entering the delivery chamber 1200 flows out from the second connecting hole 1020. In this way, when the output gear 3200 drives the actuator 2000, the actuator 2000 can be moved in the second direction without changing the moving direction of the output gear 3200, which is more conducive to the control of the driving mechanism 3000.

[0078] It can be understood that by alternately engaging and disengaging the toothed portion 3210 with the rack portion 2100 when the output gear 3200 rotates, multiple detergent dispensing can be achieved. For example, when the output gear 3200 rotates two revolutions, the toothed portion 3210 and the rack portion 2100 sequentially undergo four steps of engagement, disengagement, engagement, and disengagement. The first step causes the actuator 2000 to move in the first direction, disengaging from the first connecting hole 1010 and blocking the second connecting hole 1020. The second step causes the actuator 2000 to move in the second direction, blocking the first connecting hole 1010 and disengaging from the second connecting hole 1020. The third step causes the actuator 2000 to move in the first direction, disengaging from the first connecting hole 1010 and blocking the second connecting hole 1020. The fourth step causes the actuator 2000 to move in the second direction, blocking the first connecting hole 1010 and disengaging from the second connecting hole 1020. In this way, two detergent dispensings can be completed by rotating the output gear 3200 two revolutions. Or it can be understood that when the output gear 3200 rotates the first circle, the tooth part 3210 and the rack part 2100 first engage and then separate to complete the first dose of detergent. When the output gear 3200 rotates the second circle, the tooth part 3210 and the rack part 2100 continue to engage and then separate to complete the second dose of detergent, and so on.
