Description

Technical Field

[0001] This utility model relates to the field of washing machine accessories technology, and in particular to an intelligent linkage-type detergent and antibacterial liquid dispenser for washing machines. Background Technology

[0002] Intelligent detergent dispensing in washing machines refers to the ability of the washing machine to automatically calculate and accurately dispense the appropriate amount of detergent, fabric softener, and other laundry products based on parameters such as the weight, material, and degree of soiling of the clothes, eliminating the need for manual addition by the user. This greatly simplifies the laundry process and improves the convenience and efficiency of laundry.

[0003] A search revealed a dispensing device assembly and a washing machine in publication number CN207933738U. This utility model belongs to the technical field of washing machine accessories. The dispensing device assembly includes a dispenser and a waterproof box. The waterproof box has several first baffles on its inner walls on both sides near the handle of the dispenser, with one side's first baffles staggered to the other. This utility model, by having several first baffles on the inner walls on both sides of the waterproof box near the handle of the dispenser, and with the first baffles staggered, can effectively prevent liquid from overflowing from the gap between the waterproof box and the dispenser when there is a large backflow of liquid, thus improving the user experience. Furthermore, the first baffles can counteract the energy of the liquid backflow, causing the liquid to automatically flow back from the first baffles and into the washing machine through the waterproof box.

[0004] In the aforementioned applications, the washing machine dispenser has a relatively simple function, mainly relying on the user to manually add laundry detergent and disinfectant, and then using simple mechanical structures or water flow to dispense the detergent during the washing process. This method has several shortcomings: First, the amount dispensed is difficult to control precisely, as users often add detergent based on experience, which can easily lead to over-addition causing waste or residue, or under-addition resulting in inadequate washing; second, it cannot intelligently adjust the amount and timing of dispensing based on factors such as the type of clothing, the degree of soiling, and the washing mode, making it difficult to meet different washing needs; third, there is a lack of effective information exchange between the washing machine and the dispenser, preventing them from working together and fully utilizing the effectiveness of the detergent. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an intelligent linkage-type laundry detergent antibacterial liquid dispenser for washing machines, aiming to improve the problem of inaccurate dispensing by the dispenser.

[0012] Preferably, the power supply module is electrically connected to the metering and dispensing component module, the control module, and the communication module, respectively, and the control module is bidirectionally electrically connected to the metering and dispensing component module and the communication module, respectively.

[0013] Through the above technical solution: the power supply module provides power to the metering and dispensing component, control module and communication module through a branch circuit; the control module and metering and dispensing component interact bidirectionally to dispense data and control commands, and transmit washing parameters and equipment status bidirectionally with the communication module.

[0014] Preferably, the outer walls of the limiting block and the clamping block are slidably connected to the inner wall of the fixing block, and the outer wall of the clamping block is slidably connected to the inner wall of the machine body.

[0015] The above technical solution achieves a stable connection and quick assembly / disassembly between the dispenser and the machine body by sliding fit within the fixed block, allowing the clamping block to be inserted into or detached from the installation structure on the inner wall of the machine.

[0016] Preferably, the power supply module uses a rechargeable power supply and draws power from inside the machine body, and supplies power to the metering and dispensing component module, control module and communication module through a branch circuit.

[0035] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0036] Reference Figures 1-3 An embodiment of this utility model is provided: an intelligent linkage laundry detergent antibacterial liquid dispenser for washing machines, including a body 1, a dispenser 2 slidably connected to the outer wall of the body 1, a first liquid storage tank 3 and a second liquid storage tank 4 respectively provided on the outer wall of the dispenser 2, a metering and dispensing component module 5, a control module 6, a communication module 7 and a power supply module 8 integrated inside the dispenser 2, and a quick-release component 20 provided on the inner wall of the dispenser 2;

[0037] Specifically, the first liquid storage tank 3 and the second liquid storage tank 4 on the outer wall of the dispenser 2 independently store laundry detergent and disinfectant to avoid mixing and contamination. The inclined guide surface design at the bottom of the tank ensures that the liquid flows smoothly to the outlet. The metering and dispensing component module 5 integrated inside the dispenser 2 realizes the quantitative delivery of detergent and anti-backflow protection through the metering pump 9, one-way valve 11 and flow sensor 12. The control module 6 automatically calculates the dispensing amount and timing in combination with the washing parameters received by the communication module 7, realizing intelligent linkage with the washing machine. The power supply module 8 supports both rechargeable and machine-powered modes and is equipped with a protection circuit 19 to provide a stable and safe power supply for each module, effectively improving the automation and accuracy of detergent dispensing.

[0038] Reference Figures 6-8 The quick-release assembly 20 includes a fixing block 2001. The outer wall of the fixing block 2001 is fixedly connected to the inner wall of the dispenser 2. A pull rod 2002 is slidably connected to the inner wall of the fixing block 2001. A spring 2003 is provided on the inner wall of the fixing block 2001. A limit block 2004 is fixedly connected to the outer wall of the pull rod 2002. Multiple rotating shafts 2005 are rotatably connected to the outer wall of the limit block 2004. A rotating rod 2006 is rotatably connected to the outer wall of the multiple rotating shafts 2005. Multiple clamping blocks 2007 are rotatably connected to the outer wall of the multiple rotating shafts 2005. The outer walls of the limit block 2004 and the clamping blocks 2007 are slidably connected to the inner wall of the fixing block 2001. The outer wall of the clamping blocks 2007 is slidably connected to the inner wall of the body 1.

[0039] Specifically, the rectangular groove inside the fixing block 2001 engages with the outer wall of the pull rod 2002 to form a linear sliding motion, ensuring that the pull rod 2002 moves smoothly only axially when under force, avoiding jamming caused by lateral displacement. A spring 2003 is sleeved on the outer wall of the pull rod 2002. One end of the spring 2003 abuts against the inner wall of the fixing block 2001, and the other end contacts the end face of the limiting block 2004. When the pull rod 2002 is pulled, the spring 2003 undergoes elastic compression deformation and... Storing energy, after releasing the lever 2002, the spring 2003 releases elastic potential energy to push the lever 2002 back to its original position, achieving automatic locking. Four rotating shafts 2005 are symmetrically arranged on both sides of the limit block 2004. The rotating shafts 2005 allow the rotating rod 2006 and the clamping block 2007 to move freely around the rotating shafts 2005. The clamping block 2007 can engage with the slot on the inner wall of the machine body 1 to ensure that the clamping block 2007 is locked inside the machine body 1, realizing the quick assembly and disassembly of the dispenser 2 on the outer wall of the machine body 1.

[0040] Reference Figures 3-5 The metering and dispensing component module 5 includes a metering pump 9, a dispensing pipe 10, a one-way valve 11, and a flow sensor 12. The metering pump 9 and the dispensing pipe 10 are installed on the outer wall of the dispenser 2. The one-way valve 11 and the flow sensor 12 are both installed inside the pipe 10. The control module 6 includes a core control unit 13, a connection component 14, and a built-in functional module 15. The communication module 7 includes a communication interface 16 and a data interaction component 17. The power supply module 8 includes a power supply unit 18 and a protection circuit 19. The power supply module 8 is electrically connected to the metering and dispensing component module 5, the control module 6, and the communication module 7, respectively. The control module 6 is bidirectionally electrically connected to the metering and dispensing component module 5 and the communication module 7, respectively. The power supply module 8 uses a rechargeable power supply and draws power from inside the body 1, and supplies power to the metering and dispensing component module 5, the control module 6, and the communication module 7 through a branch circuit. The protection circuit 19 adopts an overcharge protection circuit, an over-discharge protection circuit, and an overcurrent protection circuit, respectively. The communication module 7 supports Bluetooth and WIFI wireless communication protocols.

[0041] Specifically, the metering pump 9 is connected to the outlets of the first liquid storage tank 3 and the second liquid storage tank 4, respectively, to extract laundry detergent and disinfectant liquid, which are then delivered to the inner drum of the washing machine via the dispensing pipe 10. A one-way valve 11 is installed near the inner drum on the pipe, preventing backflow and contamination of the liquid storage tanks during washing through a one-way conduction structure, ensuring the liquid flow is from the liquid storage tank to the metering pump 9, then to the one-way valve 11, the flow sensor 12, and finally to the inner drum. The flow sensor 12 monitors the detergent dispensing flow rate in real time and generates a data signal, which is transmitted to the core control unit 13 via the connection component 14 of the control module 6. The core control unit 13, combined with the washing parameters received by the communication module 7, such as the mode and the weight of the clothes, adjusts the working state of the metering pump 9 through the logic operations of the built-in function module 15, achieving dynamic calibration of the dispensing amount and ensuring accurate dispensing in different washing scenarios. The communication interface 16 of the communication module 7 supports Bluetooth and WIFI wireless communication protocols, establishing a bidirectional connection with the washing machine through the data interaction component 17, receiving washing signals from the washing machine. The system provides control commands for modes, water levels, and rotation speeds. It also feeds back real-time information such as the dispenser's liquid level, operating status, and fault information to the washing machine's main control system or user terminal. The power supply module 8 employs two power supply modes: a rechargeable power unit 18 and internal power from the machine body 1. Through a branch circuit design, it independently powers the metering pump 9, flow sensor 12, control module 6, and communication module 7, avoiding circuit interference between modules and improving system stability. The protection circuit 19 integrates overcharge, over-discharge, and overcurrent protection functions. It automatically cuts off the charging circuit when the power unit 18 is fully charged, stops discharging when the charge level is below the safety threshold, and quickly fuses for protection in case of abnormal current, effectively extending battery life and ensuring electrical safety. The modular design, through the unidirectional anti-backflow structure and flow monitoring feedback of the metering dispensing component module 5, the intelligent calculation and command execution of the control module 6, the multi-protocol wireless interaction of the communication module 7, and the dual power supply guarantee and triple protection mechanism of the power supply module 8, achieves automated control of the detergent dispensing process, improving dispensing accuracy and system reliability.

[0042] Working Principle: The dispenser 2 is installed by sliding connection with the outer wall of the machine body 1. The first liquid storage tank 3 and the second liquid storage tank 4 on its outer wall store laundry detergent and disinfectant, respectively. The inclined guide surface at the bottom of the tanks ensures smooth flow of liquid into the metering and dispensing component module 5. The communication module 7 integrated inside the dispenser 2 establishes a wireless connection with the machine body 1 through a communication interface 16 supporting Bluetooth and WIFI. The data interaction component 17 receives parameters such as washing mode and clothing weight from the machine body 1 and transmits them to the control module 6. The core control unit 13 of the control module 6 works in conjunction with the built-in functional module 15 through the connecting component 14 to calculate the dosage and timing of laundry detergent and disinfectant based on a preset algorithm. For example, in standard wash mode, 5kg of clothing requires 40ml of laundry detergent and 20ml of disinfectant. After calculation, the control module 6 sends a command to the metering and dispensing component module 5, and the metering pump 9 dispenses at 0.1... Liquid is drawn from the storage tank at a flow rate of 10 ml / s for laundry detergent or 0.05-5 ml / s for antibacterial solution. After passing through a one-way valve 11 to prevent backflow of washing water, the flow data is monitored in real time by a flow sensor 12 and fed back to the control module 6, forming a closed-loop control with bidirectional electrical connection to ensure low dispensing accuracy. Finally, the detergent is delivered into the inner drum of the machine body 1 through the dispensing pipe 10. The power supply module 8 uses a rechargeable power supply or draws power from inside the machine body 1, and supplies power to the metering dispensing component module 5, the control module 6, and the communication module 7 through a branch circuit. The protection circuit 19 simultaneously realizes overcharge, over-discharge, and overcurrent protection to ensure the safe operation of the system. The remaining amount monitoring logic built into the control module 6 continuously calculates the storage liquid volume. When the liquid in any storage tank is lower than the 20% threshold, an alarm signal is sent to the machine body 1 through the communication module 7 to realize intelligent linkage and precise dispensing control throughout the entire process.

[0043] The fixing block 2001 is fixedly connected to the inner wall of the dispenser 2. The pull rod 2002 can slide on the inner wall of the fixing block 2001 and abut against the spring 2003. The limiting block 2004 on the outer wall of the pull rod 2002 is rotatably connected to the rotating rod 2006 and the clamping block 2007 respectively through the rotating shaft 2005. When the pull rod 2002 is pulled by an external force, the spring 2003 is compressed, the limiting block 2004 moves synchronously with the pull rod 2002 and drives the rotating shaft 2005 to rotate, thereby driving the rotating rod 2006 and the clamping block 2007 to rotate around the shaft. 2005 acts as a pivot point, causing the clamping block 2007 to disengage from the mounting groove on the inner wall of the machine body 1. At this time, the dispenser 2 can be slidably disassembled along the outer wall of the machine body 1. When the external force is removed, the spring 2003 resets and pushes the pull rod 2002 back. The limiting block 2004 drives the clamping block 2007 into the mounting groove of the machine body 1 through the rotating shaft 2005. The sliding cooperation between the limiting block 2004 and the inner wall of the fixing block 2001 ensures that the clamping block 2007 is stably engaged, thereby realizing the quick disassembly and mechanical fixation of the dispenser 2 and the machine body 1.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
