Description

Technical Field

[0001] This invention relates to the field of garment processing technology, and more specifically to a garment processing device and a receiving component therefor. Background Technology

[0002] Washing equipment (such as washing machines) typically uses detergent in the process of washing clothes. Accordingly, washing equipment is equipped with a detergent dispenser for holding the detergent. With people's increasing demand for delicate laundry care, single garment treatment agents, i.e., regular detergents, are no longer sufficient. Other garment treatment agents such as fabric softeners, disinfectants, and wool-specific detergents have appeared on the market.

[0003] Corresponding to the various laundry detergents required for delicate laundry care, mechanisms capable of precise dispensing are needed for these detergents. For example, in a front-loading washing machine with precise dispensing capabilities, the amount of any laundry detergent dispensed each time should be accurate to 1 ml. Currently, laundry detergent dispensing is typically measured by volume, which presents a problem: if the ambient temperature differs significantly from the design reference temperature, the weight of the same volume of detergent will vary noticeably (from a precise dispensing perspective), affecting the performance of the precise dispensing model. For instance, during product research, the inventors discovered that some villa owners use their washing machines outdoors, such as on balconies. The outdoor temperature itself deviates from the design reference temperature, and the temperature difference in outdoor environments can reach up to 50°C throughout the year. Therefore, from a precise dispensing perspective, there is a common problem of "less dispensing in summer and more dispensing in winter."

[0004] Furthermore, since most garment treatments currently use a suction method for dispensing, drawing too quickly or when the treatment is almost depleted can create air bubbles. These bubbles are measured as volume, which indirectly reduces the amount of treatment needed.

[0005] Accordingly, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0006] In view of the inaccuracy problem in the current dispensing mechanism of laundry detergent that uses volume as the unit of measurement, the first aspect of the present invention provides a receiving assembly for a laundry detergent device, the laundry detergent device including a laundry detergent tank, the receiving assembly including: 1) a measuring basket for holding laundry detergent, the measuring basket being movably disposed in the laundry detergent device; and 2) a rinsing section including a rinsing pipe capable of dispensing pressurized rinsing liquid; wherein, when the weight of the laundry detergent held in the measuring basket reaches a set value, the measuring basket can be moved to align at least a portion of its opening side with the rinsing pipe, thereby: under the flushing force of the pressurized rinsing liquid, the laundry detergent held in the measuring basket is transferred to the laundry detergent tank.

[0007] With this setup, the movement of the measuring basket and the coordination of the rinsing pipe can ensure that the laundry detergent of a set weight is added to the laundry detergent bin, thereby ensuring that the laundry detergent is added to the laundry detergent bin by weight.

[0008] It should be noted that the term "clothes handling drum" here refers to the inner drum of a front-loading washing machine, the inner drum of a top-loading washing machine, and any other type of clothes handling equipment used to hold clothes to be processed.

[0009] It is understood that those skilled in the art can determine the arrangement of the measuring basket on the clothing processing bin and the resulting form of activity based on the actual situation, such as rotation or a combination of rotation and movement.

[0010] In one possible implementation of the aforementioned receiving assembly, at least a portion of the body of the metering basket is provided with micropores, thereby enabling: the metering basket to receive viscous laundry detergent when it is not being rinsed; allowing at least a portion of the laundry detergent to seep out during rinsing; and allowing the seepage of rinsing liquid with a viscosity lower than that of the laundry detergent, as well as a mixture of rinsing liquid and laundry detergent with a viscosity close to that of the rinsing liquid.

[0011] This design allows for the sustainability of both the metering basket's receiving and rinsing functions.

[0012] Specifically, the metering basket can reliably collect the detergent before rinsing to ensure accurate measurement. After rinsing, the collection function of the metering basket is fully restored because both the collected (to be discharged) laundry detergent and the rinsing liquid that assists in the discharge of the laundry detergent are drained.

[0013] In one possible implementation of the above-mentioned receiving assembly, the basket body includes a first portion near the opening side and a second portion away from the opening side, with the micropores distributed on at least the second portion.

[0014] This configuration provides a specific distribution pattern of micropores on the measuring basket. Those skilled in the art can select the pore size, density, and specific distribution area of ​​the micropores according to the actual situation. For example, the measuring basket could have a structure that tapers from the opening side towards the bottom section along the depth direction, with the first and second parts having the same depth. Micropores are distributed on the bottom and sidewalls of the second part, with the micropore density on the sidewalls slightly less than that at the bottom; etc.

[0015] In one possible implementation of the above-mentioned receiving assembly, the rinsing section includes a liquid guide tube. The laundry detergent collected in the metering basket reaches the upstream end of the liquid guide tube under the scouring force of the rinsing liquid, and the downstream end of the liquid guide tube is connected to the laundry treatment bucket.

[0016] With this setup, a predetermined amount of laundry treatment agent, collected in the metering basket, can be dispensed into the laundry treatment bucket through the combination of the rinsing tube and the liquid guide tube.

[0017] In one possible implementation of the above-mentioned receiving assembly, the rinsing section includes a receiving platform having a liquid-gathering area, and the upstream end of the liquid guide tube is disposed in the liquid-gathering area.

[0018] This setup provides a specific method for configuring the liquid guide tube.

[0019] Understandably, provided that the mixture of rinsing liquid and laundry detergent can be facilitated to reach the upstream end of the liquid guide tube, those skilled in the art can select the location and specific form of the liquid-gathering area on the receiving platform according to the actual situation. For example, the liquid can gather from the outer periphery to the center or from one side to the other.

[0020] Furthermore, provided that it can be used with the metering basket and rinsing pipe, those skilled in the art can choose the specific form of the receiving platform according to the actual situation. For example, it can be an existing structure of the garment processing equipment or an added structure.

[0021] In one possible implementation of the above-mentioned receiving assembly, the receiving assembly further includes: a magnetic assembly comprising a counterweight and a magnetic component; wherein the magnetic component is capable of possessing multiple magnetic properties, thereby enabling the magnetic component to generate multiple magnetic attraction forces with the counterweight; a lever having the counterweight and the measuring basket respectively disposed on both sides of its fulcrum; so that: after the weight of the laundry detergent contained in the measuring basket reaches multiple preset values ​​corresponding to the multiple magnetic attraction forces, the measuring basket overcomes the gravity of the counterweight and the corresponding magnetic attraction forces and rotates downwards, thereby aligning at least a portion of the opening side of the measuring basket with the rinsing tube.

[0022] In one possible implementation of the above-described receiving assembly, the lever corresponding to the first lever arm of the counterweight is less than the lever corresponding to the second lever arm of the measuring basket.

[0023] This setup provides a specific distribution of the counterweight and the measuring basket on both sides of the lever.

[0024] In one possible implementation of the above-mentioned receiving assembly, the lever is configured with a support platform, and the magnetic component is disposed on the support platform.

[0025] This setup provides a specific configuration for the magnetic component.

[0026] In one possible implementation of the above-mentioned receiving assembly, the support platform is provided with a limiting structure so that when the counterweight reaches its lowest position, the counterweight and the magnetic component are in a relative position that do not contact each other and are only at least partially aligned.

[0027] This setup provides a specific form for simulating weight by constructing counterweights and magnetic components.

[0028] A second aspect of the present invention provides a garment processing apparatus, which is configured with a receiving component for garment processing apparatus as described in any of the preceding claims.

[0029] It is understood that this garment processing equipment has all the technical effects of the aforementioned garment processing equipment receiving components, which will not be repeated here. Attached Figure Description

Detailed Implementation

[0035] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0036] It should be noted that in the description of this invention, terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," indicating directional or positional relationships, are based on the directional or positional relationships shown in the accompanying drawings. These are merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0037] Furthermore, to better illustrate the present invention, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that the present invention can be implemented even without certain specific details. In some instances, well-known principles of stoves and other technologies are not described in detail to highlight the main points of the present invention.

[0038] Taking a front-loading washing machine as an example, a front-loading washing machine mainly includes an outer drum and an inner drum that is rotatably installed inside the outer drum. A door is located on the front of the outer drum, allowing the user to place clothes to be washed into the inner drum or remove washed clothes from the inner drum when the door is open. A motor is located at the rear of the inner drum, driving it to rotate. The washing principle of a front-loading washing machine is as follows: the motor drives the drum to rotate around its axis, thereby causing some of the clothes soaked in the washing water to be repeatedly lifted and tumbled inside the drum, thus cleaning the clothes by mimicking the action of a stick striking the clothes.

[0039] Front-loading washing machines are typically equipped with a heating module, which is mainly used to heat the wash water to a certain degree to facilitate the dissolution of laundry detergent and to promote its decomposition of stains. Therefore, for the same amount of clothes to be washed, the amount of laundry detergent consumed will differ depending on the temperature of the wash water.

[0040] When a drum washing machine is placed outdoors, assuming the outdoor environment is a northern winter, the density of the laundry detergent will increase as the temperature decreases. If the designed volume of laundry detergent is used to wash the clothes, there will be an issue of adding too much detergent. Furthermore, if a heating module is used, referring to the previous explanation of the impact of the heating module on the laundry detergent, its use should reduce the amount of detergent needed. Therefore, under the coexistence of the conditions of "placing the washing machine outdoors in a northern winter environment" and "using the heating module to heat the washing water," assuming the designed volume of laundry detergent is added, there will inevitably be a problem of overdosing. This is the starting point for this invention, or rather, the application scenario in which this invention is particularly suitable.

[0041] This invention provides a drum washing machine, specifically a precision dispensing model equipped with a laundry detergent dispensing device. This device primarily ensures the accurate dispensing of the laundry detergent. (See reference...) Figure 1 and Figure 2 , Figure 1 This diagram illustrates the structure of a garment treatment agent dispensing device for a drum washing machine according to an embodiment of the present invention. Figure 2 A schematic diagram of a receiving assembly for a drum washing machine according to an embodiment of the present invention is shown. Figure 1 and Figure 2 As shown, in one possible implementation, the structure of the laundry detergent dispensing device, which includes a receiving component (a metering basket with receiving, metering, and dispensing functions; and an electromagnetic balance component including a counterweight), mainly includes a detergent dispenser 1 for holding the laundry detergent, a two-position two-way valve 2 capable of switching the detergent dispenser between a dispensing state that allows the laundry detergent to flow out and a non-dispensing state that blocks the flow of the laundry detergent, an electromagnetic balance component 3 for weighing the dispensed laundry detergent, and a rinsing pipe 4 serving as a rinsing section for dispensing the laundry detergent into the inner drum. Wherein:

[0042] 1) Detergent dispenser:

[0043] The detergent dispenser includes at least one storage unit, each storage unit corresponding to a laundry detergent. For ease of description, this embodiment uses a detergent dispenser with one storage unit as an example. The storage unit 1 mainly includes a housing 11, a recessed structure 12, a guide tube 13, and a float 14, specifically:

[0044] The housing 11 contains a cavity for holding laundry detergent. The lower end of the guide tube 13 extends out of the bottom wall of the housing 11 and connects to the inlet 21 of the two-position two-way valve 2. If the guide tube 13 is a flexible hose with a small radial dimension (hereinafter referred to as a hose), the upper end of the hose can rise and fall with the float 14 as the liquid level of the laundry detergent changes. The float 14 is located at the upper end of the hose. The float 14 is mainly used to keep the upper end of the hose at a position slightly below the liquid level of the laundry detergent in the cavity. By setting the float 14, the upper end of the hose can always be about 1-2 mm below the liquid level, thus ensuring that the laundry detergent can smoothly enter the hose. Under the constraint of float 14, the laundry detergent with a certain viscosity can enter the hose through the upper opening and slowly slide down the narrow tube wall to the lower opening instead of pouring directly to it. When it flows to the lower opening, the pressure and flow rate of the laundry detergent tend to be uniform. The bottom wall of the shell 11 has a recessed structure 12, so that when the laundry detergent is about to run out, the float 14 can be precisely accommodated or can be freely accommodated in the position of the bottom wall of the shell 11 corresponding to the recessed structure 12. While restricting the movement space of the float 14, setting this structure as a recessed structure 12 lower than the bottom wall of the shell can also ensure that the laundry detergent can be used up to the maximum extent before replenishment.

[0045] Preferably, the housing 11 has a flat structure (relatively small height dimension) to minimize the pressure difference caused by height, thereby stabilizing the pressure of the laundry detergent at the inlet 21 of the two-position two-way valve 2. In this way, in the initial state before the laundry detergent is dispensed, the hose of the detergent box 1 is full of laundry detergent, and the pressure of the laundry detergent near the lower end of the hose will be higher. When dispensing begins, the earliest portion of the laundry detergent stored in the hose will be transferred entirely to the metering basket 38 of the electromagnetic balance assembly 3. After stable dispensing, i.e., after the two-position two-way valve 2 has been open for a certain period, the laundry detergent in the detergent box will slowly flow down the hose wall into the metering basket 38. The pressure and flow rate of the flowing laundry detergent in the hose will gradually decrease and tend to stabilize. Specifically, the gradually decreasing pressure and flow rate are basically unaffected by the liquid level of the laundry detergent stored in the hose. In this way, after the balance of the electromagnetic balance assembly 3 is broken, the amount of clothing treatment agent that continues to flow out will be significantly reduced during the period when the counterweight 31 of the electromagnetic balance assembly 3 begins to rotate until the two-position two-way valve 2 is closed.

[0046] In addition, the housing 11 is provided with a filling port 15 for allowing users to replenish (e.g., refill) laundry detergent. The filling port 15 is equipped with a cover having a vent 16 to maintain pressure balance between the inside and outside of the housing 11 during use of the detergent dispenser. When the storage unit 1 is designed for easy removal, the filling port 15 is preferably located near the center of the upper surface of the housing 11. This prevents the laundry detergent from overflowing through the filling port 15 during vibration, even if the filling is slightly full.

[0047] 2) Two-position two-way valve 2:

[0048] The two-position two-way valve 2 mainly includes a valve body 22 with an inlet 21 (above) and an outlet 26 (below). The valve body 22 has a valve cavity inside, which contains a valve core 24 that can move freely inside. By moving the valve core 24, the two-position two-way valve 2 can switch between open and closed states.

[0049] Specifically, when the two-position two-way valve 2 is opened by applying external force, the inlet 21 and outlet 26 are connected. At this time, the laundry detergent in the detergent dispenser can enter the valve cavity through the inlet 21 and reach the metering basket 38 of the electromagnetic balance assembly 3 through the outlet 26. In this state, the detergent dispenser is in a condition where laundry detergent can be added. However, when the two-position two-way valve 2 is closed, the inlet 21 and outlet 26 are not connected, and the laundry detergent entering the valve cavity through the inlet 21 cannot reach the metering basket 38 of the electromagnetic balance assembly 3 through the outlet 26. In this state, the detergent dispenser is in a condition where laundry detergent cannot be added.

[0050] In one possible implementation, the valve core 24 is magnetized and equipped with a push rod 25. The first end (left end) of the push rod 25 extends out of the valve body 22, and the second end (right end) of the push rod 25 is fixedly connected to the first end (left end) of the valve core 24. A first electromagnet 23 is disposed within the valve cavity near the second end (right end) of the valve core 24, and the magnetism of the second end of the valve core 24 is limited to be the same as that of the first electromagnet 23 when the first electromagnet 23 is energized. Thus:

[0051] 21) When the first electromagnet 23 is energized, the valve core 24 can move from the second end to the first end (from right to left) under the action of the magnetic repulsion force generated between the first electromagnet 23 and the valve core 24, until the valve body 22 opens the outlet 26, thereby putting the two-position two-way valve 2 in the open state.

[0052] 22) When the first electromagnet 23 is de-energized, it transforms into a regular iron core. By applying external force to the first end of the push rod 25, the valve core 24 can move from the first end to the second end (from left to right). During the movement of the valve core 24 from left to right under the action of external force, the magnetic attraction between the iron core of the first electromagnet 23 and the valve core 24 promotes this movement until the valve body 22 blocks the outlet 26, thereby putting the two-position two-way valve 2 in the closed state. In other words, when an external force is applied to the first end of the push rod 25 and the first electromagnet 23 is de-energized, the two-position two-way valve 2 can reliably switch to the closed state.

[0053] Preferably, the magnetism of the first electromagnet 23 when energized should be significantly greater than that of the second end of the valve core 24. This way, when the first electromagnet 23 is energized, the magnetic repulsion force based on its magnetism can push the valve core 24 a certain distance to the left, reliably opening the two-position two-way valve 2. However, when de-energized, the magnetic attraction force of the valve core 24 itself is insufficient to move it to the right to close the two-position two-way valve 2. An external force must be applied to the first end of the push rod 25 simultaneously. That is, under the combined action of the magnetic attraction force and the external force, the valve core 24 can be moved to the right to the closed position of the two-position two-way valve 2. Specifically, when an external force is applied to the push rod 25, the valve core 24 first moves a small distance to the right. Then, a large magnetic attraction force is generated between the valve core 24 and the first electromagnet 23. With this increased magnetic attraction force, the two-position two-way valve 2 can be switched to the closed state using only the magnetic attraction force, thus eliminating the need for further external force application. Provided that the closing of the two-way valve 2 can be achieved more quickly, the amount of clothing treatment agent produced during this period will be reduced, and the resulting dosage error will be smaller.

[0054] Of course, even after the magnetic attraction force increases, an external force can still be continuously applied. Those skilled in the art can flexibly adjust the specific form of switching the two-position two-way valve 2 to the closed state according to the availability of the external force. As can be seen from the description of the electromagnetic balance assembly below, adjusting only the magnetism of the first electromagnet 23 is much more convenient than simply adjusting the magnetism of the first electromagnet 23, which is more readily available than external force.

[0055] Of course, the above example is only one specific implementation method. Those skilled in the art can flexibly choose the method of switching the state of the two-position two-way valve 2 according to the actual situation. For example, it can be: changing the magnetic pole of the first electromagnet 23 by reversing the current to speed up the process of switching the two-position two-way valve 2 to the closed state; etc.

[0056] Preferably, the first end of the push rod 25 is provided with a push platform 27 with a relatively large cross-sectional area so that the external force from the counterweight 31 of the electromagnetic balance can be stably and reliably applied to the first end of the push rod 25.

[0057] 3) Electromagnetic balance assembly:

[0058] The electromagnetic balance assembly mainly includes a second electromagnet 34 with adjustable magnetism as an electromagnetic component, a measuring basket 38 for holding laundry detergent, and a counterweight 31 that is movable when the weight of the laundry detergent in the measuring basket 38 reaches a set value. Specifically:

[0059] By moving the counterweight 31, when the weight of the garment treatment agent reaches the set value, an external force can be applied to the first end of the push rod 25. As mentioned above, through the cooperation of this external force and the first electromagnet 23, the two-position two-way valve 2 can be switched to the closed state.

[0060] The second electromagnet 34 is mainly used in conjunction with the counterweight 31 to construct multiple simulated gravity corresponding to different washing programs. Specifically, when the second electromagnet 34 is not energized, the simulated weight is the weight of the counterweight 31. When the second electromagnet 34 is energized, the magnetic attraction force on the counterweight 31 can be changed by adjusting the current of the second electromagnet 34, thereby constructing a simulated weight corresponding to the amount of detergent added for different washing programs.

[0061] The number of second electromagnets 34 can be one or more. Taking multiple electromagnets as an example, the second electromagnets 34 can have the same magnetism, and the amount of electricity supplied can be controlled to achieve the dosage control corresponding to different washing programs. Theoretically, it is also possible to use multiple second electromagnets 34 with different magnetisms, and these multiple second electromagnets 34 can be movably positioned below the lower end of the counterweight block 31. When different second electromagnets 34 reach below the lower end of the counterweight block 31, they are energized to achieve the dosage control corresponding to different washing programs. However, for this alternative solution, the difficulty and complexity of achieving precise control of the moving distance will be significantly increased. Therefore, the former method is easier to implement when not necessary.

[0062] In this way, when the weight of the laundry detergent reaches the set value corresponding to different washing programs, an external force is applied to the first end of the push rod 25. That is, for any washing program, the counterweight 31 starts to move after reaching the weight corresponding to that washing program, thus switching the two-position two-way valve 2 to the closed state.

[0063] In one possible implementation, the counterweight 31 has an arc-shaped structure. It should be noted that the arc-shaped structure here should be understood as a roughly strip-shaped structure with its axis roughly forming an arc. For example, the radial dimensions of the strip-shaped structure can be equal or unequal; for instance, the radial dimension of a certain part of the strip-shaped structure along its axial direction can be significantly larger or smaller. With this arrangement, the two ends of the counterweight 31 can correspond to the second electromagnet 34 and the push rod 25 on the two-position two-way valve 2, respectively. This allows for the construction of a simulated weight corresponding to the weight of the clothing treatment agent in the measuring basket 38, and also allows for the application of an external force to the push rod 25 by overcoming simulated gravity.

[0064] In a preferred embodiment, the counterweight 31 is an arc-shaped structure with approximately equal radial dimensions. The curvature of the arc is consistent with its motion trajectory, that is, the counterweight 31 can rotate around an axis 32 passing through the center of the arc and perpendicular to the plane containing the arc. The upper end of the counterweight 31 can abut against the push table 27 to apply an external force to the first end of the push rod 25, while the lower end of the counterweight 31 is aligned with the second electromagnet 34. The electromagnetic balance assembly 3 includes a lever 33, with the axis of the rotating shaft 32 serving as the fulcrum of the lever 33. The counterweight 31 is fixed to the first end (left end) of the lever 33, and a measuring basket 38 for holding the laundry detergent is fixed to the other end (right end) of the lever 33. In this way, after the garment treatment agent in the measuring basket 38 reaches a certain weight, if more garment treatment agent is added into it, the counterweight 31 will overcome the constructed simulated gravity and move closer to the first end of the push rod 25 by rotating around the pivot 32, and further apply external force to the first end of the push rod 25.

[0065] In one specific implementation, the fulcrum of lever 33 is eccentrically positioned, and the lever arm of counterweight 31 is significantly smaller than that of the metering basket 38. This configuration allows the two-position, two-way valve 2 to switch to the closed state more quickly, thanks to the rinsing force generated by the rinsing pipe 41. Specifically, when the amount of laundry detergent added reaches the set value, the metering basket 38 tilts and is rinsed by clean water from the rinsing pipe 41. At this time, the rinsing force helps the two-position, two-way valve 2 switch to the closed state more quickly. Since the rinsing force acting on the metering basket 38 is much greater than the external force exerted by counterweight 31 on the push platform 27 and the magnetic attraction between the valve core 24 and the first electromagnet 23, this configuration significantly accelerates the speed at which the two-position, two-way valve 2 switches to the closed state. In other words, the actual speed at which the two-position, two-way valve 2 switches to the closed state is much faster than its speed at which it switches to the open state.

[0066] Understandably, once the weight of the laundry detergent reaches the set value, theoretically, the outlet 26 of the two-position two-way valve 2 should be closed immediately to stop the detergent from being dispensed into the measuring basket 38. However, since it takes time for the counterweight 31 to rotate into position (at which point the valve body begins to move) and for the valve body 22 to move into position (at which point the outlet 26 closes), the dispensing of the laundry detergent will inevitably be delayed. In reality, once the amount of laundry detergent dispensed reaches the set value, the dispensing device will quickly close the two-position two-way valve 2. Therefore, the sum of the aforementioned two delay times is very small. Furthermore, due to the effect of the hose, the amount of laundry detergent flowing in during the latter part of the dispensing cycle is very small. Therefore, this error is not on the same order of magnitude as the aforementioned inaccurate dispensing due to temperature. In one example, the amount of laundry detergent dispensed during this time period can be experimentally measured, and then corrected by fine-tuning the simulated counterweight.

[0067] For example, since the weights of the counterweights 31 and the measuring basket 38 connected to both ends of the lever 33 are very light (typically not exceeding 100g), the lever 33 is preferably made of an ultra-lightweight material to improve sensitivity and reduce error. The material of the counterweight 31 can be entirely or only the part closest to the second electromagnet 34 made of a magnetically conductive material such as iron. Taking the part closest to the second electromagnet 34 as an example, the material of the counterweight 31 can be selected and adjusted according to the actual situation to construct a counterweight with better weight, shape, and other configurations. For example, the cross-section of the arc-shaped structure is not the same along the length direction; the counterweight is other regular geometric structures or irregular structures that can swing back and forth between the two positions aligned with the second electromagnet 34 and the push table 27; etc.

[0068] Preferably, lever 33 has a limiting structure, such as a limiting block 35, near the fulcrum (on the side near the counterweight 31). This ensures that when the counterweight 31 reaches its lowest position, the lever 33 remains horizontal due to the obstruction of the limiting block 35. Simultaneously, when the counterweight 31 reaches its lowest position, physical contact between the second electromagnet 34 and the counterweight 31 is avoided, maintaining a non-contact, aligned state between them.

[0069] To ensure that after the set weight of the laundry detergent is added, the counterweight 31 can promptly and quickly apply external force to the first end of the push rod 25 when the detergent is added again, the simulated weight of the counterweight 31 corresponding to different washing programs should correspond to the sum of the weight of the laundry detergent added in that washing program and the weight of the measuring basket 38. Specifically: Assuming that the simulated weight of the counterweight 31 corresponding to a certain washing program is G, the weight of the measuring basket 38 is g1, the weight of the laundry detergent added in a certain washing program is g2, the length from the center of gravity of the counterweight 31 to the rotating shaft 32 (called the lever arm of the counterweight 31) is L1, and the length from the center of gravity of the measuring basket 38 containing the minimum amount of laundry detergent to the rotating shaft 32 (called the lever arm of the measuring basket 38) is L2, then the critical condition is the condition of lever balance, that is: G = L2(g1 + g2) / L1. If the amount of clothing treatment agent added meets the critical condition, and the clothing treatment agent is added again, the counterweight 31 will promptly overcome the simulated gravity constructed by magnetic attraction and its own weight, and approach the first end of the push rod 25 by rotating clockwise around the rotating shaft 32, thereby applying an external force to the first end.

[0070] When the weight of the laundry detergent in the measuring basket 38 reaches the set value, the measuring basket 38 moves downward, causing the counterweight 31 to rotate clockwise. This applies an external force to the push platform 27 at the first end of the push rod 25, enabling the two-position two-way valve 2 to switch to the closed state. With this configuration, once the weight of the laundry detergent in the measuring basket 38 reaches the set value, the two-position two-way valve 2 can be switched to the closed state promptly and quickly. In one possible embodiment, the lever 33 is equipped with a support platform 36. For example, the support platform 36 can be installed on the body of the drum washing machine. The aforementioned second electromagnet 34, limit block 35, and support platform 37, which serves as the mounting carrier for the rotating shaft 32, are all installed on the support platform 36.

[0071] 4) Flushing pipe 4:

[0072] The rinsing pipeline 4 mainly includes a rinsing pipe 41 and a liquid guide pipe 42. The rinsing pipe 41 is mainly used to rinse the laundry detergent in the metering basket 38 and transfer it to the position corresponding to the liquid guide pipe 42. The liquid guide pipe 42 is mainly used to deliver the rinsed laundry detergent to the inner drum.

[0073] Once the weight of the laundry detergent reaches the set value, the counterweight 31 rotates upward and the measuring basket 38 rotates downward. At this time, the open side of the measuring basket 38 will be aligned with the inlet of the rinsing pipe 41. For example, when the counterweight 31 rotates to the closed position of the two-position two-way valve 2, water will flow out of the rinsing pipe 41, which can flush the laundry detergent in the measuring basket 38 to the position that the liquid guide pipe 42 can receive. Alternatively, the rinsing pipe 41 can start to flow out water before the counterweight 31 rotates to the closed position of the two-position two-way valve 2, which can flush the laundry detergent in the measuring basket 38 to the position that the liquid guide pipe 42 can receive.

[0074] The former has the advantage of better alignment between the flushing pipe 41 and the opening side when the counterweight 31 rotates to its position, resulting in a more stable flushing process. The latter has the advantage of accelerating the rotation of the counterweight 31 during flushing, thus shortening the time it takes for the two-position two-way valve 2 to switch to the closed state. Since the initial alignment of the former can be improved immediately upon rotation, and the switching time of the latter is very short and can be corrected by means of fine-tuning the simulated counterweight, those skilled in the art can flexibly choose the timing of the flushing action according to the actual situation.

[0075] The measuring basket 38 has micropores distributed on its basket body. By setting the size of the micropores, the measuring basket 38 can have the following properties:

[0076] 41) Before the weight of the garment treatment agent reaches the set value, that is, before it is rinsed, the garment treatment agent with a certain viscosity will not seep out, thus ensuring that the metering basket 38 has the function of holding and metering before it is rinsed.

[0077] 42) After the laundry detergent is rinsed off, such as after rinsing stops, any remaining clean water or laundry detergent that has been diluted to near-clean water in the measuring basket 38 can be naturally discharged through the micropores. In this way, the receiving and measuring functions of the measuring basket 38 are quickly restored as rinsing is completed.

[0078] Regarding the metering and rinsing functions of the metering basket 38, the inventors would like to make the following special explanation: The design life of a household washing machine typically includes 2000 washing cycles. Taking washing four times a week as an example, the washing machine can be used for approximately 10 years (under normal circumstances, it can be used for about 12 years). The metering basket 38 is typically made of non-magnetic stainless steel. Analyzing its design life as 4000 cycles with each rinse lasting 2 minutes (usually 1-2 minutes), the rinsing load within the design life can be converted to 5.5 days of intermittent rinsing on a stainless steel plate-shaped component. Clearly, for stainless steel components, such a rinsing volume results in almost no detectable weight loss. Therefore, when the metering basket 38 is applied to the dispensing device of this invention, its rinsing function can be reliably completed while accurately achieving its metering function.

[0079] During the rinsing process of the laundry detergent through the rinsing pipe 41, most of the detergent is rapidly discharged from the open side under the rinsing action of the water from the rinsing pipe 41, while a small portion of the diluted detergent is discharged through the micropores under the force of the rinsing. The laundry detergent discharged from the metering basket 38 can be smoothly transferred to the receiving position of the liquid guide pipe 42. For example, a receiving platform 43 is provided below the metering basket 38, and the liquid guide pipe 42 is located at the lowest point of the receiving platform 43. After the rinsed laundry detergent reaches the receiving platform 43, it gathers on the platform surface at the position corresponding to the liquid guide pipe 42 and is further released into the inner drum.

[0080] As can be seen, in the dispensing device of the present invention, a flexible tube with a float 14 is provided inside the detergent box 1, and the electromagnetic balance assembly 3 includes a measuring basket 38 capable of receiving laundry detergent. The downstream end of the flexible tube is connected to the open side of the measuring basket 38 via a two-position two-way valve 2. The counterweight 31 of the electromagnetic balance assembly 3 provides external force to the push rod 25 of the two-position two-way valve 2, so that when the amount of laundry detergent received by the measuring basket 38 reaches the standard, the two-position two-way valve 2 is closed, thereby preventing the laundry detergent in the detergent box 1 from being continuously dispensed into the measuring basket 38 via the flexible tube and the two-position two-way valve 2. Based on this, the washing pipe 4 can completely transfer the laundry detergent that meets the weight standard to the inner drum, thereby ensuring that the measuring basket 38 can be reset and continuously have the aforementioned receiving and measuring functions.

[0081] It should be noted that although the above specific structure has been described as an example, those skilled in the art will understand that the present invention is not limited thereto. In fact, users can flexibly adjust the relevant structure according to actual application scenarios and other circumstances.

[0082] The technical solution of the present invention has been described in conjunction with preferred embodiments. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions resulting from these changes or substitutions will all fall within the scope of protection of the present invention.
