[0020] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0021] In this invention, the terms "comprising," "including," "having," or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0022] In this invention, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. Additionally, in this invention, the character " / " generally indicates that the preceding and following related objects have an "and / or" relationship.

[0023] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," "fixed," "combined," "coupled," and "installed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a direct connection or an indirect connection via an intermediate medium; or the internal communication of two components or the interaction between two components. As examples, a direct connection refers to two parts or components being connected together without the need for an intermediate medium, while an indirect connection refers to two parts or components each being connected to at least one intermediate medium, with the connection achieved through the intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances. Furthermore, "connected" and "coupled" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0024] In this invention, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the value and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​not using relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0025] In this invention, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0026] In this invention, the terms "upper," "lower," "left," "right," "front," and "rear," etc., refer to the orientations or positional relationships shown in the accompanying drawings. They are used solely for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, in the context, it should be understood that when an element is mentioned as being "upper" or "lower" than another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as "upper side," "lower side," "left side," "right side," "front side," and "rear side" not only represent positive orientation but can also be understood as lateral orientation. For example, "above," "on top of," "upper side of," and "above" the first feature "above" or "on the second feature" includes the first feature being directly above, to the upper left, to the upper right, to the upper front, and to the upper rear of the second feature, or simply indicating that the first feature is at a higher horizontal level than the second feature. The terms "below," "under," "below," and "below" for "first feature" and "second feature" include situations where the first feature is directly below, to the lower left, to the lower right, in front of, or behind the second feature, or simply indicate that the first feature is at a lower horizontal level than the second feature. Furthermore, the terms "first" and "second" are used merely for descriptive distinction and have no specific meaning.

[0027] With technological advancements, the types of home appliances have become increasingly diversified, with dishwashers dominating the market. To ensure ease of use, dishwashers are typically equipped with automatic dispensing devices for convenient dispensing of consumables. Common dispensing devices include a liquid pump and a liquid reservoir, and most are located inside the dishwasher's mounting plate. The liquid pump is a consumable component and is prone to malfunction after prolonged use. However, repairing or replacing the liquid pump requires disassembling the dishwasher, which after-sales service cannot perform at the user's home. In such cases, the dishwasher must be returned to the factory for disassembly and reshipment after maintenance. This not only increases service costs and maintenance time but also significantly reduces the user experience and affects ease of use. To address the problems in the prior art, this embodiment provides a dispensing device. The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0028] like Figures 1 to 6 As shown, this dispensing device includes a dispensing mechanism 10, a pump suction structure 20, a liquid storage box 30, and a driving component 40. The dispensing mechanism 10 is located on the outside of the mounting plate 100 and has a receiving space 111 with a replenishment port 13. The pump suction structure 20 is detachably installed in the receiving space 111. The liquid storage box 30 is located on the inside of the mounting plate 100, and the replenishment port 13 is connected to the liquid storage space 31 of the liquid storage box 30, which is used to store consumable liquid. The driving component 40 is located on the inside of the mounting plate 100 and is configured to drive the pump suction structure 20 to draw consumable liquid.

[0029] In this structure, the dispensing mechanism 10 and the pump suction structure 20 are both located on the outside of the mounting plate 100, while the liquid storage box 30 and the drive component 40 are located on the inside of the mounting plate 100. Therefore, the entire dispensing device is essentially semi-embedded in the mounting plate 100 of the dishwasher. Users can inject consumable liquid into the liquid storage box 30 through the replenishment port 13 and extract the consumable liquid from the liquid storage box 30 through the pump suction structure 20. When the pump suction structure 20 needs to be repaired or replaced, since it is located on the outside of the mounting plate 100, the pump suction structure 20 can be directly removed from the receiving space 111 without having to send it to the original manufacturer for disassembly. This greatly improves the replacement speed, reduces disassembly time, improves the convenience of disassembly, ensures good maintenance efficiency, and allows users to install new pump suction structures 20 themselves, significantly improving the user experience.

[0030] It should be noted here that, in this embodiment, as Figures 1 to 6As shown, the dispensing mechanism 10 includes a dispensing base 11 and a flip cover 12. The dispensing base 11 has a receiving space 111. The flip cover 12 is pivotally connected to the top of the dispensing base 11 to open and close the receiving space 111. A replenishment port 13 is provided on the dispensing base 11. When it is necessary to replenish the consumable liquid, the flip cover 12 can be opened to replenish the consumable liquid into the storage space 31 through the replenishment port 13. When it is necessary to replace the pump suction structure 20, it is only necessary to remove the entire pump suction structure 20 from the dispensing base 11. The structure is simple and the operation is convenient. In addition, the pump suction structure 20 is plugged into or snapped onto the dispensing base 11. When it is necessary to replace it, it is only necessary to pull out the entire pump suction structure 20 to complete the disassembly, and then press it to complete the installation. No additional tools are required, which fully ensures the convenience of operation.

[0031] Specifically, such as Figures 1-6 As shown, the pump suction structure 20 includes a pump base, a central frame 21, and a liquid outlet pipe 23. The central frame 21 is pivotally connected to the pump base, and the liquid outlet pipe 23 is installed circumferentially along the pump base. The liquid storage box 30 has a liquid outlet channel 37, one end of which is connected to the liquid storage space 31, and the other end is connected to the liquid outlet pipe 23. The rotating end of the drive component 40 is driven to the central frame 21 to drive the central frame 21 to rotate. When the central frame 21 rotates, it can squeeze the liquid outlet pipe 23, so that the consumable liquid can flow out from the end of the liquid outlet pipe 23 away from the liquid outlet channel 37. This configuration is not only simple in structure, but also convenient to install and use. The drive end 41 of the drive component 40 can be driven to form a transmission connection with the central frame 21, so that the rotation of the drive end 41 can drive the central frame 21 to rotate. At the same time, the central frame 21 can continuously squeeze the liquid outlet pipe 23, thereby realizing liquid discharge.

[0032] In addition, such as Figure 4 As shown, the central frame 21 is equipped with multiple pulleys 26 along the circumferential direction. All pulleys 26 are pivotally connected to the central frame 21, and can take turns squeezing the liquid outlet pipe 23. When the central frame 21 rotates, it drives the multiple pulleys 26 to rotate together and squeeze the liquid outlet pipe 23. The multiple pulleys 26 can rotate around their pivot positions, thereby reducing the frictional resistance between the pulleys 26 and the liquid outlet pipe 23 and improving the smoothness of liquid discharge.

[0033] Preferably, such as Figures 1-6 As shown, the pump suction structure 20 also includes a connector 22, which has an inlet port 221 and an outlet port 222. The inlet port 221 has an inlet section 223 communicating with it, and the outlet port 222 has an outlet section 224 communicating with it. The inlet section 223 is installed in the outlet channel 37, and both ends of the outlet pipe 23 are respectively connected to the inlet port 221 and the outlet port 222. By setting the connector 22, both ends of the outlet pipe 23 can be connected to the inlet port 221 and the outlet port 222 respectively, and the inlet port 221 can be connected to the outlet channel 37 through the inlet section 223, thereby greatly improving the ease of installation of the outlet pipe 23.

[0034] It should be noted that in this embodiment, the liquid outlet tube 23 is consumed relatively quickly and needs to be replaced regularly. However, by setting the connector 22, the liquid outlet section 224 can dispense liquid under normal working conditions. When replacement is required, the liquid inlet section 223 of the connector 22 can be directly removed from the liquid outlet channel 37, and then both ends of the liquid outlet tube 23 can be removed from the liquid inlet interface 221 and the liquid outlet interface 222 respectively. The operation is simple and convenient, and can ensure normal liquid dispensing effect.

[0035] Preferably, such as Figure 4 As shown, the pump base includes a pump cover 24 and a base body 25. The base body 25 is disposed within the receiving space 111 of the dispensing seat 11. The pump cover 24 is detachably installed on the side of the base body 25 opposite to the dispensing seat 11. The outlet pipe 23 is arranged circumferentially along the base body 25. This arrangement not only has a simple structure, but the detachable connection also greatly improves the convenience of replacing the outlet pipe 23, ensuring a good user experience.

[0036] In addition, such as Figure 2 As shown, the liquid storage box 30 includes an upper shell 32 and a lower shell 33, forming a liquid storage space 31 between the upper shell 32 and the lower shell 33. The upper shell 32 and the lower shell 33 can be integrally formed or separately formed. This design is not only simple in structure and convenient for liquid storage, but also has good performance. It should be noted that in this embodiment, if a separate forming structure is adopted, the upper shell 32 and the lower shell 33 are detachably connected to ensure convenient maintenance in the later stage; alternatively, non-detachable methods such as welding or bonding can be used for connection. If an integral forming structure is adopted, the liquid storage box 30 can be manufactured by processes such as blow molding. The appropriate method can be selected for production based on actual needs or processing conditions.

[0037] Preferably, such as Figure 1 and Figure 2 As shown, if a one-piece molding structure is adopted, the clearance groove 34 can be directly formed on the outside of the liquid storage box 30 during blow molding; if a split processing method is adopted, both the upper shell 32 and the lower shell 33 have clearance parts, and after the upper shell 32 and the lower shell 33 are connected, the two clearance parts can form the clearance groove 34; and the clearance groove 34 formed by the above two methods can both avoid the drive component 40. By setting the clearance groove 34, the drive component 40 can be placed outside the liquid storage box 30 without interfering with the liquid storage box 30, simplifying the installation structure and facilitating the maintenance of the drive component 40, while not increasing the space occupied inside the mounting plate 100, resulting in good performance.

[0038] Considering that as the consumable liquid in the storage space 31 decreases, there may be problems with dispensing. Therefore, if Figure 3As shown, the dispensing mechanism 10 has a vent 14 on its dispensing seat 11, which is connected to the liquid storage space 31. In this structure, the vent 14 is connected to the liquid storage space 31, thus ensuring that the air pressure in the liquid storage space 31 is equal to the external air pressure. Therefore, the situation where the liquid inlet or outlet is affected by air pressure issues is prevented, thus ensuring the smooth flow of liquid inlet and outlet.

[0039] Furthermore, considering that the reservoir 30 is located inside the mounting plate 100, it is inconvenient for users to observe the level of consumable fluid. To solve this problem, the reservoir 30 has a float 35 and a sensor 36. The float 35 can communicate with the sensor 36 to transmit information about the level of consumable fluid in the reservoir 30. When the consumable fluid is about to run out, the float 35 drops to its lowest point, and the float 35 communicates with the sensor 36, thereby transmitting a signal to the control structure, which then issues an alarm message indicating insufficient consumable fluid. The user can then open the flip cover 12 and replenish the consumable fluid through the replenishment port 13 (during the replenishment process, the vent 14 can maintain a constant air pressure in the reservoir space 31 to ensure smooth replenishment). It should be noted that the float 35 can communicate with the sensor 36 through either magnetic or photoelectric sensing, and the relevant sensing and communication structures are all within the scope of protection disclosed in this embodiment.

[0040] This embodiment also provides a dishwasher, which includes a body and the aforementioned dispensing device. The body has a mounting plate 100. The dispensing mechanism 10 and the pump suction structure 20 of the dispensing device are both located on the outer side of the mounting plate 100, while the liquid storage box 30 and the drive component 40 are both located on the inner side of the mounting plate 100. This dishwasher utilizes the aforementioned dispensing device to achieve semi-recessed installation, meaning that the pump suction structure 20 and the dispensing mechanism 10 are both located on the outer side of the mounting plate 100, ensuring convenience for replenishing consumable liquid and replacing the dispensing pipe 23.

[0041] In summary, the dispensing device in this embodiment solves the problem of inconvenience in disassembling the pump suction structure 20 in the prior art, improves maintenance efficiency, reduces the complexity of the maintenance process, and reduces repair time. The dishwasher in this embodiment, by applying the aforementioned dispensing device, significantly enhances the user experience.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
