CONTENT OF THE UTILITY MODEL

[0003] The present application aims to at least partly solve one of the problems in the related art. To this end, the present application proposes a dispensing device.

[0004] To achieve the above-mentioned purpose, the present application discloses a dispensing device, which is suitable for being installed on a door body of a washing appliance, the door body is vertically arranged when in a closed state and is horizontally arranged when in an open state, the dispensing device comprises:

[0005] a main body, which is provided with a storage cavity, a partition cavity and a discharge port, the storage cavity and the partition cavity are communicated, the partition cavity and the discharge port are communicated, the storage cavity is suitable for containing washing agent in a liquid state, when the door body is in the open state, the washing agent is suitable for entering the partition cavity from the storage cavity, when the door body is switched from the open state to the closed state, the storage cavity and the partition cavity respectively retain washing agent, and the washing agent in the storage cavity and the washing agent in the partition cavity are isolated; and

[0006] an actuator, which is suitable for plugging the discharge port and separating from the discharge port, the actuator is suitable for preventing the washing agent in the partition cavity from flowing out of the discharge port when plugging the discharge port, the actuator is suitable for causing the washing agent in the partition cavity to flow out of the discharge port to a washing cavity of the washing appliance when separating from the discharge port.

[0007] In some embodiments of the present application, a communication port is arranged between the storage cavity and the partition cavity, the communication port communicates the storage cavity and the partition cavity, when the door body is in the open state, the washing agent is suitable for entering the partition cavity from the storage cavity through the communication port.

[0008] In some embodiments of the present application, when the door body is in the open state, the highest point of the liquid level of the washing agent in the storage cavity is higher than the lowest point of the communication port and the lowest point of the partition cavity, so that the washing agent is suitable for entering the partition cavity from the storage cavity through the communication port.

[0009] In some embodiments of this application, when the door is closed, the highest point of the detergent level in the storage cavity is lower than the lowest point of the connecting port, and the highest point of the detergent level in the partition cavity is lower than the lowest point of the connecting port.

[0010] In some embodiments of this application, a partition is provided between the storage cavity and the partition cavity, the partition being adapted to isolate the detergent in the storage cavity from the detergent in the partition cavity when the door is in the closed state.

[0011] In some embodiments of this application, the partition is adapted to extend vertically when the door is in the closed state.

[0012] In some embodiments of this application, the volume of the storage cavity is greater than the volume of the partition cavity.

[0013] In some embodiments of this application, the main body is further provided with a feeding port, which is connected to the storage cavity to facilitate the replenishment of detergent into the storage cavity through the feeding port.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features.

If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0040] The first aspect of this application discloses a dispensing device suitable for installation on the door of a washing appliance. The door has a closed state and an open state. In the closed state, the door is vertically positioned, and in the open state, it is horizontally positioned. The washing appliance has a washing chamber in which a target object can be washed. When the door is closed, the washing chamber is closed; when the door is open, the washing chamber is open. When a target object needs to be loaded into the washing chamber, the door is open and horizontally positioned. When the target object needs to be washed, the door is closed and vertically positioned. The dispensing device is installed on the door, specifically on the inside of the door. When the door is open, detergent can be added to the dispensing device. The detergent is temporarily stored inside the dispensing device, and its dispensing is controlled during the washing process. In this embodiment, the detergent is a liquid detergent. The main function of the detergent is cleaning and stain removal, or it can assist in cleaning and stain removal. Of course, detergents with other functions can also be used, such as rinse aid.

[0041] During the washing process of a washing appliance, it is necessary to control the addition of detergent. The detergent flows out from the corresponding outlet of the dispensing device. When detergent is not needed, the corresponding outlet needs to be sealed. When the seal of the corresponding outlet fails, almost all the detergent in the dispensing device will leak into the washing chamber, resulting in excessive detergent and even corrosion of the washing chamber wall. This embodiment solves this problem.

[0042] Combination Figure 4 , Figure 6 and Figure 7As shown, in some embodiments, the dispensing device includes a main body 1000 and an actuator 2000. The main body 1000 is provided with a storage cavity 1100, a partition cavity 1200 and a discharge port 1210. The storage cavity 1100 and the partition cavity 1200 are connected. When the door is in the open state, detergent enters the partition cavity 1200 from the storage cavity 1100. It can be understood that as long as detergent enters the partition cavity 1200, regardless of the amount of detergent entering the partition cavity 1200, it can be regarded as detergent entering the partition cavity 1200 from the storage cavity 1100. When the door switches from the open state to the closed state, the storage cavity 1100 and the partition cavity 1200 respectively retain detergent, and the detergent in the storage cavity 1100 is isolated from the detergent in the partition cavity 1200. In other words, when the door is in the open state, a portion of the detergent enters the compartment 1200 from the storage chamber 1100, while the remaining detergent remains in the storage chamber 1100. When the door switches from the open state to the closed state, the aforementioned portion of the detergent remains in the compartment 1200, and the aforementioned remaining detergent remains in the storage chamber 1100. The detergent in the storage chamber 1100 is isolated from the detergent in the compartment 1200. It can be understood that the isolation of the detergent in the compartment 1200 from the detergent in the storage chamber 1100 means that in this state, the detergent in the compartment 1200 cannot enter the storage chamber 1100, and the detergent in the storage chamber 1100 cannot enter the compartment 1200.

[0043] The diaphragm 1200 is connected to the discharge port 1210, through which detergent is dispensed. Detergent dispensing requires the cooperation of an actuator 2000. The actuator 2000 can block or disconnect from the discharge port 1210. When blocking the discharge port 1210, the actuator 2000 prevents detergent from being discharged from the diaphragm 1200 through the discharge port 1210. When disconnecting from the discharge port 1210, the actuator 2000 allows detergent to flow from the diaphragm 1200 into the washing chamber. In other words, when detergent needs to be added, the control actuator 2000 disengages from the discharge port 1210, and the detergent flows out from the discharge port 1210 into the washing chamber, thus realizing the addition of detergent. After the addition of detergent is completed, the control actuator 2000 blocks the discharge port 1210, and the detergent cannot flow out from the discharge port 1210. It should be noted that the detergent can flow directly into the washing chamber from the discharge port 1210 or indirectly into the washing chamber.

[0044] During the washing process of a washing appliance, if the seal of the actuator 2000 on the discharge port 1210 fails, the detergent in the diaphragm 1200 will leak out from the discharge port 1210. However, in this state, because the detergent in the diaphragm 1200 is isolated from the detergent in the storage chamber 1100, even if all the detergent in the diaphragm 1200 leaks, the detergent in the storage chamber 1100 will not enter the diaphragm 1200 and leak through the discharge port 1210. This reduces the amount of detergent leakage when the seal of the discharge port 1210 fails. In particular, the amount of detergent stored in the diaphragm 1200 can be designed to be the amount required for a single wash. Even if all the detergent in the diaphragm 1200 leaks out during a single wash, although it is not at a suitable washing stage, the impact on the washing process can still be reduced compared to related technologies.

[0045] Combination Figure 4 and Figure 6 As shown, in some embodiments, a connecting port 1001 is provided between the storage cavity 1100 and the partition cavity 1200. The connecting port 1001 connects the storage cavity 1100 and the partition cavity 1200. When the door is in the open state, detergent can enter the partition cavity 1200 from the storage cavity 1100 through the connecting port 1001. The storage cavity 1100 and the partition cavity 1200 are connected through the connecting port 1001. When the door is in the open state, the dispensing device is also horizontally positioned. A portion of the detergent enters the partition cavity 1200 from the storage cavity 1100 through the connecting port 1001, and the remaining portion of the detergent remains in the storage cavity 1100. When the door is switched from the open state to the closed state, the dispensing device changes from horizontal to vertical positioning. The aforementioned portion of the detergent remains in the partition cavity 1200 and cannot enter the storage cavity 1100 through the connecting port 1001, and the aforementioned remaining portion of the detergent remains in the storage cavity 1100 and cannot enter the partition cavity 1200 through the connecting port 1001.

[0046] Optionally, in some embodiments, when the door is open, the highest point of the detergent level in the storage cavity 1100 is higher than the lowest point of the connecting port 1001 and the lowest point of the partition 1200, so that the detergent can enter the partition 1200 from the storage cavity 1100 through the connecting port 1001. In this state, because the detergent level in the storage cavity 1100 is higher, the detergent can pass through the connecting port 1001 and enter the partition 1200 under the action of gravity until the detergent level in the partition 1200 is the same as the detergent level in the storage cavity 1100. Detergent is present in both the partition 1200 and the storage cavity 1100. This arrangement facilitates the entry of detergent from the storage cavity 1100 through the connecting port 1001 into the partition 1200 when the door is open.

[0047] Optionally, in some embodiments, when the door is closed, the highest point of the detergent level in the storage cavity 1100 is lower than the lowest point of the connecting port 1001, and the highest point of the detergent level in the partition cavity 1200 is lower than the lowest point of the connecting port 1001. In this state, since the lowest point of the connecting port 1001 is higher than both the detergent level in the partition cavity 1200 and the detergent level in the storage cavity 1100, the detergent in the partition cavity 1200 cannot enter the storage cavity 1100 through the connecting port 1001, and the detergent in the storage cavity 1100 cannot enter the partition cavity 1200 through the connecting port 1001, thus isolating the detergent in the partition cavity 1200 from the detergent in the storage cavity 1100.

[0048] Taking a single door opening and closing process as an example, when the door is open, the detergent level in storage chamber 1100 is higher, allowing the detergent to pass through the connecting port 1001 and enter the compartment 1200 under gravity, until the detergent level in compartment 1200 and storage chamber 1100 are the same. Detergent is present in both compartment 1200 and storage chamber 1100. When the door switches from open to closed, the detergent in compartment 1200 falls back down under gravity until its level is below the lowest point of connecting port 1001, and the detergent in storage chamber 1100 also falls back down under gravity until its level is below the lowest point of connecting port 1001. At this point, detergent remains in both compartment 1200 and storage chamber 1100.

[0049] Combination Figure 4 , Figure 6 and Figure 7 As shown, in some embodiments, a partition 1370 is provided between the storage cavity 1100 and the partition cavity 1200. The partition 1370 is adapted to isolate the detergent in the storage cavity 1100 and the detergent in the partition cavity 1200 when the door is closed. The partition 1370 facilitates the isolation of the detergent in the partition cavity 1200 from the detergent in the storage cavity 1100.

[0050] Combination Figures 4 to 7As shown, the orientation is with the door closed as a reference. The user stands in front of the washing appliance to control the opening and closing of the door. 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, rear wall 1320, left side wall 1330, right side wall 1340, top wall 1350, and bottom wall 1360 together enclose a certain space. A partition 1370 is set 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 communication opening 1001. The bottom of the partition 1370 is connected to the bottom wall 1360, thus dividing the storage cavity 1100 and the partition cavity 1200. When the door is open, the partition 1200 and the storage chamber 1100 are arranged horizontally. At this time, detergent can enter the partition 1200 from the storage chamber 1100 through the connecting port 1001. When the door is closed, the partition 1200 and the storage chamber 1100 are arranged vertically. Through the isolation of the partition 1200, the detergent in the partition 1200 cannot enter the storage chamber 1100, and the detergent in the storage chamber 1100 cannot enter the partition 1200.

[0051] 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 compartment 1200 and the storage compartment 1100, which helps to maximize the use of space.

[0052] Combination Figure 7 As shown, in some embodiments, the volume of the storage cavity 1100 is greater than the volume of the partition cavity 1200, for example, the volume of the storage cavity 1100 is two, three, four or more times the volume of the partition cavity 1200. By such a configuration, the frequency of replenishing detergent can be reduced.

[0053] Taking a dishwasher as an example, the detergent is rinse aid. When using the dishwasher for the first time, the door opens, dishes (the target items) are loaded into the washing chamber, and rinse aid (detergent) is injected into the storage chamber 1100. At this time, some rinse aid enters the partition chamber 1200 from the storage chamber 1100. Then, the door closes, leaving rinse aid in both the partition chamber 1200 and the storage chamber 1100. During the washing process, the actuator 2000 disengages from the discharge port 1210, and the rinse aid in the partition chamber 1200 is discharged from the discharge port 1210 into the washing chamber. After the rinse aid is added, the actuator 2000 blocks the discharge port 1210. After the washing cycle is complete, the door opens again, the dishes (the target items) are removed, and the door closes. During the process of opening and closing the door after the washing cycle, some rinse aid enters the partition chamber 1200 from the storage chamber 1100, leaving rinse aid in both the partition chamber 1200 and the storage chamber 1100.

[0054] When using the dishwasher for the second time, the control door opens, the dishes (target items) are loaded into the washing chamber, and then the control door closes. At this time, the partition chamber 1200 and the storage chamber 1100 respectively retain rinse aid. During the washing process, the control actuator 2000 disengages from the discharge port 1210, and the rinse aid in the partition chamber 1200 is discharged from the discharge port 1210 into the washing chamber. After the rinse aid is added, the control actuator 2000 blocks the discharge port 1210. After the washing is finished, the control door opens, the dishes (target items) are removed, and then the door is closed. During the process of opening and closing the door after the washing is finished, some rinse aid enters the partition chamber 1200 from the storage chamber 1100, so that the partition chamber 1200 and the storage chamber 1100 respectively retain rinse aid.

[0055] Similarly, the size of the storage cavity 1100 and the partition cavity 1200 can be designed according to the actual situation, so that it is not necessary to add rinse aid to the storage cavity 1100 every time the dishwasher is used, but only after multiple uses of the dishwasher.

[0056] Understandably, because the volume of the storage chamber 1100 is larger than that of the partition chamber 1200, under multiple uses of the dishwasher, the amount of detergent entering the partition chamber 1200 remains constant each time the dishwasher is used, until the amount of detergent in the storage chamber 1100 decreases below a certain level. This ensures a consistent detergent dispensing rate during the first few uses of the dishwasher. Understandably, the amount of detergent in the storage chamber 1100 can be monitored by a detection device to remind the user to replenish it in time. For example, the amount of detergent entering the partition chamber 1200 is consistent during the first 20 door openings and closings, but decreases during the 21st door opening and closing. This ensures a consistent detergent dispensing rate during the first 20 uses, and an alarm can be triggered on the 21st use to remind the user to replenish the detergent.

[0057] Combination Figure 1 and Figure 2 As shown, in some embodiments, the main body 1000 is also provided with a feeding port 1110, which is connected to the storage cavity 1100 to facilitate the replenishment of detergent into the storage cavity 1100 through the feeding port 1110. When detergent needs to be replenished, the door is in the open state, and the dispensing device is arranged approximately horizontally. The user can replenish detergent into the storage cavity 1100 through the feeding port 1110. After the detergent enters the storage cavity 1100, a portion of the detergent enters the partition cavity 1200. It is understood that the main body 1000 is generally provided with a cover 1120, which is used to close and open the feeding port 1110.

[0058] Combination Figure 3 , Figure 8 , Figure 9 and Figure 10As shown, in some embodiments, the dispensing device further includes a drive mechanism 3000, which is adapted to drive the actuator 2000 to move so that the actuator 2000 disengages from the discharge port 1210. The drive mechanism 3000 is a component that can output power. By setting the drive mechanism 3000, the automatic dispensing of detergent during the washing process can be realized.

[0059] Optionally, combined Figure 11 and Figure 12 As shown, in some embodiments, the drive mechanism 3000 includes an output gear 3200, the output gear 3200 is provided with a toothed portion 3210, the actuator 2000 is provided with a rack portion 2100, and the output gear 3200 is adapted to drive the actuator 2000 to move by meshing the toothed portion 3210 and the rack portion 2100 when rotating.

[0060] The drive mechanism 3000 outputs power through the output gear 3200, thereby driving the actuator 2000. The output gear 3200 outputs power in a rotating manner. For example, the drive mechanism 3000 includes a power source 3100, which can be of various types, such as a motor that converts electrical energy into mechanical energy. Specifically, 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. The movement of the actuator 2000 is specifically manifested as the rotation of the output gear 3200 driving the actuator 2000 to move. When the output gear 3200 rotates, the gear tooth 3210 rotates accordingly. Through the meshing of the gear tooth 3210 with the rack part 2100, the rotation of the output gear 3200 drives the rack part 2100 to linearly displace, thereby causing the actuator 2000 to disengage from the discharge port 1210.

[0061] Combination Figure 11 and Figure 12 As shown, in some embodiments, the toothed portion 3210 is adapted to separate from the rack portion 2100 after the actuator 2000 disengages from the discharge port 1210. The dispensing device also includes an elastic element 4000, which is adapted to generate force on the actuator 2000 to drive the actuator 2000 toward the discharge port 1210 after the toothed portion 3210 and the rack portion 2100 separate, so as to block the discharge port 1210.

[0062] Specifically, the toothed part 3210 is not arranged along the entire circumference of the output gear 3200, but at a certain position on the circumference of the output gear 3200. Thus, when the output gear 3200 rotates, the toothed part 3210 meshes with the rack part 2100 and drives the actuator 2000 to disengage from the discharge port 1210. When the output gear 3200 continues to rotate at a certain angle, the toothed part 3210 separates from the rack part 2100. In this embodiment, by setting an elastic element 4000, the elastic element 4000 generates force on the actuator 2000. When the output gear 3200 rotates and the toothed part 3210 meshes with the rack part 2100, thereby driving the actuator 2000 to disengage from the discharge port 1210, the elastic element 4000 undergoes elastic deformation to accumulate elastic potential energy and generate force on the actuator 2000. When the output gear 3200 continues to rotate at a certain angle, the toothed part 3210 separates from the rack part 2100, and the elastic element 4000 releases elastic potential energy, thereby driving the actuator 2000 to move towards the discharge port 1210 and block the discharge port 1210. In this way, when the output gear 3200 drives the actuator 2000, it is not necessary to change the direction of the output gear 3200 to block the discharge port 1210, which is more conducive to the control of the drive mechanism 3000.

[0063] Understandably, by alternately engaging and disengaging with the rack section 2100 as the output gear 3200 rotates, multiple detergent dispensing operations can be achieved. For example, when the output gear 3200 rotates two revolutions, the gear part 3210 and the rack section 2100 sequentially undergo four steps: engagement, disengagement, engagement, and disengagement. The first step causes the actuator 2000 to disengage from the discharge port 1210; the second step causes the actuator 2000 to block the discharge port 1210; the third step causes the actuator 2000 to disengage from the discharge port 1210; and the fourth step causes the actuator 2000 to block the discharge port 1210. Thus, two rotations of the output gear 3200 complete two detergent dispensing operations. Alternatively, it can be understood that when the output gear 3200 rotates for the first time, the toothed part 3210 and the rack part 2100 first mesh and then separate to complete the first addition of detergent. When the output gear 3200 rotates for the second time, the toothed part 3210 and the rack part 2100 continue to mesh and then separate to complete the second addition of detergent, and so on.

[0064] Combination Figure 11 and Figure 12As shown, in some embodiments, the actuator 2000 includes a flexible sealing plug 2200, which is adapted to disengage from and block the discharge port 1210 via the sealing plug 2200. Specifically, the flexible sealing plug 2200 is elastically deformable. For example, the sealing plug 2200 is made of materials such as silicone or rubber. With this configuration, when the actuator 2000 blocks the discharge port 1210, the sealing plug 2200 contacts the discharge port 1210 and blocks it, causing the sealing plug 2200 to deform, thereby better sealing the discharge port 1210.

[0065] The second aspect of this application discloses a washing appliance, which can be a dishwasher, a washing machine, etc. Of course, the washing appliance can also be other types of products. The washing appliance includes the above-mentioned dispensing device, which is used to install on the door of the washing appliance. The door has a closed state and an open state. When the door is closed, it is vertically arranged. When the door is open, it is horizontally arranged. Vertical can be understood as roughly up and down. Horizontal and vertical are perpendicular, which can be understood as horizontal direction.

[0066] The dispensing device includes a main body 1000 and an actuator 2000. The main body 1000 is provided with a storage chamber 1100, a partition chamber 1200 and a discharge port 1210. The storage chamber 1100 and the partition chamber 1200 are connected. When the door is open, detergent enters the partition chamber 1200 from the storage chamber 1100. When the door is closed, detergent is stored in both the storage chamber 1100 and the partition chamber 1200, and the detergent in the storage chamber 1100 is isolated from the detergent in the partition chamber 1200. The diaphragm 1200 is connected to the discharge port 1210, through which detergent is dispensed. Detergent dispensing requires the cooperation of the actuator 2000. The actuator 2000 can block or disconnect from the discharge port 1210. When blocking the discharge port 1210, the actuator 2000 prevents detergent from being discharged from the diaphragm 1200. When disconnecting from the discharge port 1210, the actuator 2000 allows detergent to flow from the discharge port 1210 into the washing chamber.

[0067] By configuring a storage chamber 1100 and a partition chamber 1200, the storage chamber 1100 is mainly used to store detergent. After each opening and closing of the door, a portion of the detergent enters and remains in the partition chamber 1200, while the remaining detergent remains in the storage chamber 1100. During the washing process of the washing appliance, even if the seal of the actuator 2000 on the discharge port 1210 fails, the detergent leaks from the partition chamber 1200, not the storage chamber 1100. This configuration prevents a large amount of detergent from entering the washing chamber when the seal of the actuator 2000 on the discharge port 1210 fails. It is understood that the dispensing device of the washing appliance in this embodiment adopts the technical solution of the above embodiment, and therefore has at least the beneficial effects brought by the technical solution of the above embodiment, which will not be repeated here.

[0068] The above description is merely a preferred embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
