Technical Field
[0001] This utility model belongs to the technical field of washing machine accessories, specifically relating to an automatic dispensing device with a pre-dissolving function. Background Technology
[0002] Washing machines typically have an automatic dispensing device that adds various types of detergent, with laundry powder being commonly used in daily laundry. The degree of dissolution of the laundry powder during rinsing directly affects the final washing result. A patent with publication number CN111962263A discloses a detergent dispenser assembly and a washing machine, including a detergent dispenser and a water inlet box to house the detergent dispenser. The detergent additives dispensed from the detergent dispenser are flushed into the water inlet box with the water flow and flow out from the outlet of the water inlet box. The water inlet box is equipped with a device to divert and block the flowing water, trapping lumps of detergent additives carried in the water flow. The trapping device in this invention can block large, undissolved pieces of detergent powder and other lumpy detergent additives. While existing detergent dispenser assemblies improve detergent dissolution through trapping devices, these devices only have a blocking function, resulting in relatively poor overall dissolution. Therefore, an automatic dispensing device with a pre-dissolving function is needed to overcome these difficulties. Summary of the Invention

[0012] Preferably, the second layer of the mixer body is provided with a pair of first filter elements, and the mixer body is provided with a filter element mounting groove, in which the first filter elements are installed; the two first filter elements are arranged side by side; the end of the second layer of the mixer body is provided with a water outlet, which is connected to the detergent dispensing chamber.
[0013] Preferably, the second layer of the mixer body is provided with a plurality of evenly distributed lifting ribs, each of which is staggered with the others.
[0014] When the inlet valve is opened, water first enters the main water path, and then flows from the main water path into two branch water paths. The inlet valve is electrically connected to the control panel on the washing machine, allowing for easy adjustment of its operation. When the inlet valve allows water to enter for short periods multiple times, the two branch water paths converge on the sloped path due to the ramp on the main water path. One end of the ramp has a baffle, and the other end has an overflow outlet. Water flows from the showerhead and overflow outlet to the first layer of the mixer body. The water level cannot overflow the water outlet on the baffle, and the oscillating vane assembly is in the default closed state. Through repeated short-term water entry via the inlet valve, water accumulates in the pre-dissolving tank, allowing the detergent to soak. Excess water overflows from the overflow tank on the first layer of the mixer body, flowing into the main water storage tank.
[0015] After dissolving for a period of time, the water inlet valve continues to supply water for an extended period. The water inlet valve's inlet status can be set via the control panel on the washing machine. The water inlet speed on the main water line is greater than the speed flowing out from the showerhead and overflow outlet, causing the water level to overflow the water inlet on the baffle rib. The small diameter of the water inlet allows the water to flow quickly towards the jet nozzle. The jet nozzle generates a certain water pressure that sprays onto the swing vane assembly. The water flow overcomes the spring force of the torsion spring, thus opening the swing vane body. This allows the water to flush away the pre-dissolved detergent and flow from the drain hole to the second layer of the mixer body. After the water inlet valve stops supplying water, the swing vane body returns to its default closed state. The swing vane body's on / off state can cycle multiple times, thereby improving the overall dissolution efficiency of the detergent.
[0016] The mixture of laundry detergent and water flows out from the drain hole, driving the impeller to rotate and further accelerating the mixing and dissolution. The mixture then flows over the lifting ribs on the mixer body; because the lifting ribs are unevenly arranged and staggered, the mixed solution is buffered during flow, increasing the stirring effect and further improving the mixing efficiency. The mixed solution impacts the first filter element at a certain speed; this allows the laundry detergent, water, and air to mix effectively, forming a large amount of foam and improving the washing effect. The first filter element not only generates a large amount of foam but also has a filtering effect, preventing impurities in the laundry detergent from entering the water storage tank. After passing through the first filter element, the mixed solution finally flows along the drain hole into the laundry detergent dispensing chamber of the dispenser box body, and then flows along the laundry detergent dispensing chamber into the water storage tank body.
[0017] In daily life, the water pressure in the tap water network is not stable. When the water pressure is low, traditional detergent dispensing devices lack a pre-dissolving function, resulting in incomplete detergent rinsing. Here, a flow detection component works in conjunction with the control panel inside the washing machine to implement flow detection. After detergent is added to the detergent dispensing chamber, the dispenser box is pushed into the water tank. During this process, the flow meter moves along a sliding groove. Once the dispenser box is locked, the sensing end of the flow meter is directly above the magnet. The flow meter also provides a guiding effect, facilitating the insertion of the dispenser box into the water tank. Because the magnet has a north pole and a south pole, the magnet generates different electrical signals as the impeller rotates. The flow meter counts the number of rotations and the control panel automatically calculates the flow rate through the mixer. This flow detection is a commonly used detection mode in existing technology and will not be discussed further. If the impeller does not rotate during the washing process, it indicates low water pressure, which is insufficient to open the impeller assembly. During the washing process, the impeller rotates, but at a slow speed. This indicates that the water pressure is low; it can force open the vane assembly, but there is a risk of incomplete rinsing. If the impeller rotates quickly during the washing process, the water pressure is normal. The flow detection component and control panel allow for direct analysis of the water pressure, enabling the control panel to regulate the on / off time of the inlet valve, thus ensuring that the detergent is rinsed thoroughly.
[0018] Compared with the prior art, the present invention has the following advantages: 1. The detergent mixer assembly and the water circuit board assembly cooperate with each other, so that the detergent is pre-dissolved in both layers of the mixer body, resulting in a better overall dissolution effect; 2. By setting the swing blade assembly, it is convenient to control the on / off state of the mixer body, so that water can be gathered on the mixer body to wet the detergent; 3. By setting the flow detection assembly, the impeller body accelerates the dissolution of detergent and can also detect the water flow rate, thus facilitating the setting of the working time of the water inlet valve.

Two first filter elements 9 are arranged side-by-side. A water outlet 11 is provided at the end of the second layer of the mixer body 51, and the water outlet 11 communicates with the detergent dispensing chamber 42. The second layer of the mixer body 51 is provided with a plurality of evenly distributed lifting ribs 12, each of which is staggered.
[0025] The specific operation process of this embodiment is as follows: when the water inlet valve 3 is turned on, the water will first enter the main water passage 25, and then enter the two branch water passages 26 from the main water passage 25. Here, the water inlet valve 3 is electrically connected to the control panel on the washing machine, so that the working state of the water inlet valve 3 can be easily adjusted. When the inlet valve 3 introduces water for short periods of time multiple times, the two branch waterways 26 converge on the waterway where the ramp 28 is located because the main waterway 25 is also equipped with a ramp 28. One end of the ramp 28 is equipped with a baffle 29, and the other end of the ramp 28 is equipped with an overflow port 22. In this way, water will flow from the shower head 27 and the overflow port 22 to the first layer of the mixer body 51. At this time, the water level cannot overflow the water outlet 210 on the baffle 29. At this time, the vane assembly 6 is in the default closed state. Through the inlet valve 3 introducing water for short periods of time multiple times, the water can be collected in the pre-dissolving tank 53, so that the laundry detergent can be soaked. If there is excess water, it will also overflow from the overflow tank 56 on the first layer of the mixer body 51. The overflowed liquid will flow to the water storage tank body 1.
[0026] After dissolving for a period of time, water enters through the inlet valve 3 for an extended period. The water inlet status of the inlet valve 3 can be set via the control panel on the washing machine. The water inlet speed on the main water path 25 is greater than the speed of water flowing out from the showerhead 27 and overflow outlet 22, so the water level will overflow the water outlet 210 on the baffle rib 29. The outlet 210 has a small aperture, so the water will flow towards the jet outlet 21 at a faster speed. The jet outlet 21 can generate a certain water pressure to spray onto the swing vane assembly 6. The water flow overcomes the elasticity of the torsion spring 62, thus putting the swing vane body 61 in the open state. In this way, the water flow can rinse the previously pre-dissolved laundry detergent and flow from the drain hole 52 to the second layer of the mixer body 51. After the inlet valve 3 stops entering water, the swing vane body 61 returns to the default closed state. The swing vane body 61 can cycle through multiple opening and closing states, thereby improving the overall dissolution efficiency of the laundry detergent.
[0027] The mixture of laundry detergent and water flows out from the drain hole 52, driving the impeller body 71 to rotate, further accelerating the mixing and dissolution. The mixture then flows over the lifting ribs 12 on the mixer body 51; because the lifting ribs 12 are unevenly arranged and staggered, the mixed solution is buffered during flow, increasing the stirring effect and further improving the mixing efficiency. The mixed solution impacts the first filter element 9 at a certain speed; this allows the laundry detergent, water, and air to mix effectively, forming a large amount of foam and improving the washing effect; the first filter element 9 not only generates a large amount of foam but also has a filtering effect, preventing impurities in the laundry detergent from entering the water storage tank body 1. After passing through the first filter element 9, the mixed solution finally flows along the drain hole 11 into the laundry detergent dispensing chamber 42 of the dispenser box body 41, and then flows along the laundry detergent dispensing chamber 42 into the water storage tank body 1.
[0028] In daily life, the water pressure in the tap water network is not stable. When the water pressure is low, traditional detergent dispensing devices do not have a pre-dissolving function, resulting in incomplete rinsing of the detergent. Here, the flow detection component 7 can work with the control panel inside the washing machine to implement the flow detection function. After detergent is added to the detergent dispensing chamber 42, the dispenser box body 41 is pushed into the water storage tank body 1; during the pushing process, the flow meter body 72 moves along the slide 43. After the dispenser box body 41 is pushed and locked, the sensing end of the flow meter body 72 is exactly above the magnet 74. The flow meter body 72 also has a guiding effect, facilitating the insertion of the distributor box body 41 into the water storage tank body 1. Since the magnet 74 has a north pole and a south pole, as the impeller body 71 rotates, it causes the flow meter body 72 to generate different electrical signals. The flow meter body 72 rotates several times, and the control panel automatically calculates the time, allowing the control panel to automatically calculate the flow rate through the mixer body 51. Flow detection here is a commonly used detection mode in existing technology and will not be discussed further. If the impeller body 71 does not rotate during the washing process, it indicates low water pressure, which cannot flush away the vane assembly 6. If the impeller body 71 rotates during the washing process, but at a slow speed, it indicates low water pressure, which can flush away the vane assembly 6, but there is a risk of incomplete rinsing. If the impeller body 71 rotates during the washing process at a relatively fast speed, it indicates normal water pressure. Here, the flow detection component 7 and the control panel allow for direct analysis of the water pressure, enabling the control panel to control the on / off time of the inlet valve 3, thus ensuring that the detergent is rinsed clean.
