Detailed Implementation

[0020] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present application.

[0021] It's important to understand that with consumption upgrades and the diversification of household laundry needs, the washing machine industry is rapidly evolving from traditional single-drum and twin-drum products to multi-drum models. Three-drum and above multi-drum washing machines, with their core advantages of "zoned washing and care, and high energy efficiency," are gradually becoming one of the mainstream products in the mid-to-high-end market. The core requirement for these products is to simultaneously achieve independent operation of multiple drums and separate washing of clothes within a limited cabinet space, while also incorporating automation and intelligent functions.

[0022] Traditional washing machine automatic dispensing units often adopt an integrated structural design, where core components such as the dispensing module, water inlet valve module, water circuit module, and drainage module are integrated into a single housing. The design philosophy revolves around "centralized layout and simplified assembly," reducing connections between parts by integrating all functional components to accommodate the relatively ample internal space of traditional washing machines.

[0023] However, traditional technical solutions use an integrated structure, which has problems such as complex structure, easy failure, and high requirements for the washing machine cabinet space. At the same time, after-sales maintenance requires the whole machine to be replaced, which is troublesome and costly.

[0024] This application provides an automatic dispenser and a washing machine, which can solve the problems of traditional automatic dispensers using an integrated structure design, which have complex structures, are prone to failure, and have high requirements for the space of the washing machine cabinet. After-sales maintenance requires the replacement of the entire unit, which is troublesome and costly.

[0025] Firstly, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this application embodiment provides an automatic dispenser, which includes: a dispensing port module 1, a primary water circuit module 2, an inlet valve module 3, a side plate water circuit module 4, a secondary water circuit module 5, a drainer module 6, and a tertiary water circuit module 7; the dispensing port module 1 is connected to the primary water circuit module 2; the primary water circuit module 2 and the side plate water circuit module 4 are connected via a first hose 8, and the primary water circuit module 2 and the inlet valve module 3 are connected via a second hose 9; the side plate water circuit module 4 and the secondary water circuit module 5 are connected via a third hose 10, the secondary water circuit module 5 and the drainer module 6 are connected via a fourth hose 11, and are also connected to the tertiary water circuit module 7.

[0026] In this embodiment, by breaking down the traditional integrated structure into multiple functionally independent modules, each module is flexibly connected by flexible hoses and can be arranged in a dispersed manner according to the space characteristics of the washing machine cabinet, maximizing the use of limited space and effectively adapting to the spatial layout requirements of multi-drum models; the split modular design simplifies the overall structure, reduces the probability of failure, and allows for individual replacement of faulty modules during after-sales maintenance, eliminating the need for overall replacement, thus significantly reducing maintenance difficulty and cost.

[0027] The functions of each module are explained in detail below: I. Primary Waterway Module 2: Functional Integration and Core of Waterway Connection Laundry detergent storage function: Built-in liquid storage area for storing laundry detergent, fabric softener and other laundry liquids, providing raw material reserves for automatic dispensing, and adapting to the independent storage needs of two or more laundry liquids; Self-cleaning function: After the water inlet valve module 3 supplies water, some water flows through the water distribution port into the liquid storage chamber to rinse the inner wall. At the same time, the water flows through the negative pressure pipe to generate negative pressure, which draws the cleaning wastewater from the water inlet and discharges it through the water outlet, thus realizing automatic cleaning of the liquid storage chamber. Residual water drainage function: After the washing program ends, the residual water in the water circuit falls to the water storage area by gravity. The residual water drainage pump starts and pumps the residual water through the side panel water circuit module 4 and the secondary water circuit module 5 to the drain module 6 for discharge. Automatic dispensing function: The dispensing pump draws the liquid from the storage area to the water circuit temporary storage area, and then the clean water washes it through the side plate water circuit module 4, the secondary water circuit module 5, and the tertiary water circuit module 7 and sends it into the inner drum of the washing machine. Liquid level detection function: The liquid storage area is equipped with a GND common probe, a no-liquid probe, an alarm probe, and a full-liquid probe. The liquid level height is identified by the signal difference at different liquid levels, thus realizing liquid level monitoring. Connection function: The water source is received and the liquid is delivered to the subsequent modules via the water circuit module 4 connected to the side plate via the hose 1 (8), and via the water inlet valve module 3 connected to the hose 2 (9).

[0028] Secondary Waterway Module 5: Function Switching and Waterway Transfer Hub The water path switching function for the essence wash: the water flow path is adjusted through the internal valve structure to switch between the water path for ordinary washing and the water path for essence wash, adapting to the needs of different washing modes; Intensive Wash Function: In Intensive Wash mode, the water flow from the side panel water circuit module is guided and the pressure of the laundry liquid mixture is regulated to provide conditions for the precise spraying of the subsequent mixture. Flushing water path switching function: Adjust the flushing water flow path to adapt to different scenarios such as wastewater discharge from the storage chamber and flushing of the temporary storage area; Connection function: Connect to the side plate water path module 4 via hose 3 (10), and to the drain module 6 via hose 4 (11), and connect to the three-stage water path module 7 to realize the horizontal and vertical transfer of the water path.

[0029] III. Level 3 Waterway Module 7: Mixed Liquid Delivery and Spraying Terminal Essence Wash Mixture Spray Function: Receives the mixed liquid delivered by the secondary water circuit module 5, and sprays it into the washing machine drum at a specific pressure and angle through the built-in structure to ensure cleaning and care effects; Connection function: Connects the secondary water circuit module 5 to the inner drum of the washing machine to achieve precise delivery of the mixed liquid to the target drum chamber.

[0030] IV. Drainage Module 6: Residual Water and Multi-Cylinder Drainage Centralized Treatment Unit Residual water discharge function: Receives residual water from the system delivered by the secondary water circuit module 5, and guides it through the internal channel to the drainage outlet for discharge; Multi-cylinder drainage treatment function: Sets three corresponding water inlets to receive drainage from the three cylinders (pressurized by the drainage pump), with built-in one-way ball valves to block and avoid water circuit interference, and finally discharges them uniformly through the drainage outlet.

[0031] V. Side Panel Waterway Module 4: Waterway Transfer and Spatial Adaptation Structure As an intermediate transfer module, it connects to the primary water circuit module 2 via hose 18 and to the secondary water circuit module 5 via hose 30, receiving the liquid / water flow delivered by the primary water circuit module 2 and guiding it to the secondary water circuit module 5, thus realizing the connection and transition of each level of water circuit.

[0032] In conjunction with the first aspect, in one implementation, such as Figure 1 As shown, the side panel water channel module 4 is flat and is used to install on the inner side wall of the washing machine body.

[0033] In this embodiment, the flat-designed side panel water channel module 4 adapts to the narrow installation space on the inner wall of the washing machine cabinet. Serving as an intermediate water channel transfer structure, it receives the liquid and water transported by the primary water channel module 2 and guides it to the secondary water channel module 5. This ensures smooth water channel connection while fully utilizing the unused space on the side wall of the cabinet, avoiding spatial interference with the washing machine's inner drum and other components. This design, through the flat structure of the side panel water channel module 4 and its installation adaptation to the inner wall of the cabinet, combined with the flexible connection characteristics of the rubber hoses between modules, further optimizes the utilization efficiency of the limited space in the washing machine cabinet, making the modular automatic dispensing unit more suitable for the compact spatial layout of multi-drum models.

[0034] In conjunction with the first aspect, in one implementation, such as Figure 1 As shown, along the Z-axis, the primary water channel module 2 is located below the secondary water channel module 5, and the area between them is the roller installation area.

[0035] In this embodiment, along the Z-axis, the primary water circuit module 2 is located below the secondary water circuit module 5, and the area between the two is set as the drum installation area. This layout is adapted to the installation space requirements of the drum inside the washing machine cabinet. The primary water circuit module 2 and the secondary water circuit module 5 are connected by a hose. While ensuring the stable delivery of washing liquid and water flow, the drum installation area is reasonably embedded in the space between the two modules, making full use of the layered space of the cabinet along the Z-axis and avoiding spatial interference with the washing machine drum and other components.

[0036] In conjunction with the first aspect, in one implementation, such as Figure 1As shown, along the Y-axis, the liquid inlet module 1 and the water inlet valve module 3 are located at both ends of the primary water circuit module 2, and the liquid inlet module 1 is installed on the top of one end of the primary water circuit module 2.

[0037] In this embodiment, along the Y-axis, the liquid inlet module 1 and the water inlet valve module 3 are respectively located at both ends of the primary water circuit module 2, and the liquid inlet module 1 is installed on the top of one end of the primary water circuit module 2. This layout is adapted to the functional implementation and spatial arrangement requirements of the primary water circuit module 2. The liquid inlet module 1 is located at the top of the front end of the primary water circuit module 2, which makes it convenient for users to add laundry liquid and fits their daily operating habits. The two are located at opposite ends to avoid the space congestion caused by the centralized layout of functional modules. At the same time, it provides reasonable structural support for the direct connection between the primary water circuit module 2 and the liquid inlet module 1, and the hose connection between the primary water circuit module 2 and the water inlet valve module 3. While ensuring the smooth implementation of the liquid replenishment and water inlet functions, it optimizes the space allocation between modules and avoids interference with other components inside the washing machine.

[0038] In conjunction with the first aspect, in one implementation, such as Figure 1 As shown, along the X-axis, hose 310 and drain module 6 are distributed at both ends of the secondary water circuit module 5.

[0039] In this embodiment, along the X-axis, hose 3 10 and drain module 6 are respectively located at both ends of the secondary water circuit module 5. This layout adapts to the functional connection of the secondary water circuit module 5 and the spatial characteristics of the washing machine cabinet. Hose 3 10 connects the side panel water circuit module 4 and the secondary water circuit module 5. Drain module 6 is connected to the secondary water circuit module 5 via hose 4 11 to receive residual water and to connect with other hoses to the multi-drum system for multi-drum drainage. The separation of the two at both ends allows the water inlet and drainage paths of the secondary water circuit module 5 to be arranged in an orderly manner along the X-axis, avoiding structural clutter caused by pipe crossing and entanglement. At the same time, it provides reasonable space avoidance for the decentralized installation of each module. While ensuring the smooth transfer and centralized drainage function of the water circuit system, it further optimizes the space utilization efficiency of the cabinet along the X-axis and reduces the risk of spatial interference with other components.

[0040] In conjunction with the first aspect, in one implementation, such as Figure 1 As shown, along the Z-axis, the three-stage water channel module 7 is used to be installed above the roller mounting area.

[0041] In this embodiment, along the Z-axis, the three-stage water channel module 7 is positioned above the drum mounting area. This layout adapts to the spatial structure of the washing machine cabinet and the functional requirements of the three-stage water channel module 7. The three-stage water channel module 7 is responsible for spraying the essence wash mixture and connecting to the inner drum of the washing machine. Positioning it above the drum mounting area allows for optimization of the spray angle and pressure of the mixture by utilizing the height difference, ensuring that the mixture evenly covers the clothes inside the drum. At the same time, placing it in the unused space above the drum avoids spatial conflicts with the drum and the primary and secondary water channel modules below it. While ensuring efficient spraying, it fully utilizes the longitudinal space of the cabinet along the Z-axis, further optimizing the spatial adaptability of the modular structure.

[0042] In conjunction with the first aspect, in the above embodiments, the X-axis represents the left-right direction of the washing machine, the Y-axis represents the front-back direction of the washing machine, and the Z-axis represents the height direction of the washing machine.

[0043] In conjunction with the first aspect, in one implementation, such as Figure 1 As shown, the three-level water circuit module 7 includes: a hose mounting carrier 701; a hose 702, which is mounted on the hose mounting carrier 701, and one end of the hose 702 is connected to the two-level water circuit module 5.

[0044] In this embodiment, the hose mounting carrier 701 provides a stable installation support for the hose 702, preventing the hose from shifting or falling off due to vibration during washing machine operation; the hose 702 serves as a connecting channel to connect the secondary water circuit module 5 and the tertiary water circuit module 7, ensuring stable flow of the essence wash mixture. While conforming to the functional positioning of the tertiary water circuit module 7, it is also compatible with the overall modular design, providing structural protection for the efficient realization of the mixture spraying function.

[0045] In conjunction with the first aspect, in one implementation, such as Figure 1 As shown, there are four hoses 702, all of which are connected to the secondary water circuit module 5. The first hose 702 is used to connect to the first roller, the second hose 702 is used to connect to the second roller, and the remaining two hoses 702 are used to connect to the third roller.

[0046] In this embodiment, four flexible hoses 702 are respectively set for each drum, which can realize the precise distribution of washing liquid and mixture delivered by the secondary water circuit module 5 to the three drums. The remaining two hoses provide sufficient water supply for drum three (drum three is the large drum, and drums one and two are small drums). While ensuring that each drum can independently obtain liquid, the hose mounting carrier 701 can realize the centralized and orderly arrangement of pipelines, avoiding the messy arrangement of multiple pipelines. This is consistent with the overall split modular design and provides stable water circuit support for the intelligent needs of the washing machine for zoned washing and care.

[0047] In conjunction with the first aspect, in one implementation, such as Figure 2 As shown, the liquid inlet module 1 is provided with two independent liquid inlet channels 101, and each independent liquid inlet channel 101 is connected to the primary water circuit module 2 via a flexible hose 102; the primary water circuit module 2 is provided with two independent chambers, which are respectively connected to the corresponding flexible hose 102, and the number of flexible hoses 18 is at least two, which are respectively connected to the corresponding independent chambers.

[0048] In this embodiment, the liquid dispensing module 1 has two independent dispensing channels 101. Each independent dispensing channel 101 is connected to the primary water circuit module 2 via a flexible hose 102. The primary water circuit module 2 has two independent chambers, each connected to a flexible hose 102. There are at least two flexible hoses 8, each connected to an independent chamber. This structure is suitable for the independent storage and dispensing needs of two types of laundry liquids. The two independent dispensing channels 101 can be used to add different liquids such as laundry detergent and fabric softener. The independent chambers achieve isolated storage of different liquids, avoiding mixing and deterioration. The correspondingly connected flexible hoses 102 and 8 ensure independent delivery paths for each liquid. While meeting the automatic dispensing and liquid level detection functions of the primary water circuit module 2, it also achieves zoned management and precise dispensing of two types of laundry liquids, adapting to the overall modular design and providing liquid supply support for the diverse washing and care needs of the washing machine.
