Description

Technical Field

[0001] This invention relates to the field of washing control technology, specifically to a washing control method for down garments in a pulsator washing machine. Background Technology

[0002] With the widespread use of home appliances and the advancement of technology, washing machines have become increasingly diverse in function, leading to the emergence of different types of washing machines on the market to meet the needs of different families and clothing. Down garments, as a special type of clothing, are made of soft materials with high warmth retention properties, making them susceptible to excessive friction and damage. Therefore, they require special washing methods.

[0003] In practical use, down garments often suffer from damage to the down or incomplete washing due to improper water level, impeller speed, and spin-drying process. Furthermore, traditional washing methods struggle to intelligently adjust the water level and load based on the actual load of the down garment, leading to water waste and unsatisfactory washing results.

[0004] To address these issues, some washing programs specifically designed for down garments have been developed for the market. However, most of these programs simply set fixed water levels and impeller speeds, lacking precise control over down garments. In particular, they cannot dynamically optimize water level control and impeller speed adjustment based on the weight and other characteristics of down garments. Summary of the Invention

[0005] Based on the shortcomings of the prior art described above, the purpose of this invention is to provide a washing control method for down garments in a pulsator washing machine to solve the aforementioned technical problems.

[0018] The calculation logic for the cumulative water release in the initial stage is as follows: Where W1 is the cumulative water release in the initial stage, and T1 is the duration of the initial stage.

[0019] The present invention is further configured such that the calculation logic for the water level at the current moment is: H(t) = X·H tar +C2·ln(1+k2t), where H(t) is the water level height at time t during the transition phase, X is the preset ratio, C2 is the water level growth factor, and k2 is the slow increase factor, which is used to control the rate of water level rise.

[0020] The calculation logic for the current water release volume is as follows: Where Q(t) is the amount of water released at time t during the transition phase.

[0021] The present invention is further configured to, upon reaching the target water level, control the rotation speed of the impeller according to a preset impeller control algorithm to wash down garments, including:

[0022] When the target water level is reached, the machine enters a low-speed wash cycle and smoothly accelerates to a low-speed wash rotation to ensure that down garments are initially wetted and evenly distributed.

[0023] After reaching the low-speed washing spin speed, the machine washes at low speed until the low-speed washing time is reached, then accelerates to a stable washing spin speed and performs a stable washing cycle.

[0024] The present invention is further configured to smoothly accelerate to a low washing speed, and the calculation logic is as follows: Where ω1(t) is the rotational speed at time t during low-speed washing, ω min τ is the low-speed washing rotation speed, and τ is the acceleration time constant, used to control the smoothness of acceleration;

[0025] The calculation logic for smoothly accelerating to a stable washing speed is: ω2(t) = ω min +(ω sta -ω min )·(1-e -γt ), where ω2(t) is the rotational speed at time t during steady-state washing, ω sta To stabilize the washing speed, γ is an acceleration coefficient used to adjust the speed of acceleration.

[0029] The present invention is further configured to obtain the weight of the down garment to be washed by setting a weight sensor at the bottom of the washing machine tub, and to obtain the water level by setting a water level sensor inside the washing machine tub.

[0030] This invention provides a washing control method for down garments in a pulsator washing machine. The method involves placing the down garments and detergent into the washing machine drum, closing the pressure plate, and sequentially selecting the down washing mode and one-touch smart wash. The smart wash control process begins by calculating the target water level based on the weight of the down garments, and then controlling the water level in stages according to a preset water level control algorithm. When the target water level is reached, the pulsator speed is controlled according to a preset pulsator control algorithm to wash the down garments. After washing, the pulsator speed is adjusted according to a preset spin-drying control algorithm to perform the spin-drying process. The beneficial effects include:

[0031] 1. Optimized water level control: By calculating the target water level based on the weight of down garments and performing phased water level control according to the preset water level control algorithm, the problem of excessively high or low water levels in traditional washing methods can be effectively avoided. This not only reduces water waste but also ensures that the water level of down garments is appropriate during the washing process, reducing friction and damage to the garments.

[0032] 2. Precise Spindle Speed ​​Control: The impeller speed is intelligently adjusted according to the washing and spin-drying needs of down garments, especially during the washing and spin-drying processes. Smooth acceleration during the low-speed washing phase effectively prevents down from collapsing or being damaged during washing. During spin-drying, adjusting the target spin speed avoids excessive compression of down garments, helping to maintain their shape and softness.

[0033] 3. Intelligent load detection and water level adjustment: By setting a weight sensor at the bottom of the washing machine drum and combining it with the water absorption coefficient of down clothing, the load and target water level are accurately calculated, thereby achieving more precise water level control and load optimization. It can not only automatically adjust the water level and spin speed according to the weight of the clothes, but also dynamically adjust the water flow during the washing process according to the load, improving the uniformity and efficiency of washing.

[0034] The above description is only an overview of the technical solution of this application. In order to better understand the technical means of this application and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this application more obvious and understandable, the following are specific embodiments of this application. Attached Figure Description

Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention and not for limiting the scope of protection of the present invention.

[0038] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0039] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the invention. However, it will be apparent to those skilled in the art that embodiments of the invention may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the invention.

[0040] A method for controlling the washing of down garments in a top-loading washing machine, such as Figure 1 As shown, it includes:

[0041] Place the down garments and detergent into the washing machine drum, close the pressure plate, and select the down washing mode and one-touch smart wash in sequence.

[0042] Enter the intelligent washing control process, calculate the target water level based on the weight of the down garments to be washed, and perform staged water level control according to the preset water level control algorithm based on the target water level.

[0043] When the target water level is reached, the speed of the impeller is controlled according to the preset impeller control algorithm to wash down garments;

[0044] After washing, the speed of the impeller is adjusted according to the preset dehydration control algorithm to execute the dehydration process.

[0045] Specifically, down garments are made of a special material with down filling, possessing high warmth retention properties, but their physical properties require special attention during washing. Washing down garments typically requires meticulous control to avoid damaging the down filling. Therefore, a corresponding washing control method is needed for washing down garments; a pressure plate is used to control the water level inside the washing machine and the compaction of the garments. The pressure plate's function is to help the liquid penetrate the down garments more evenly by pressing them down. The pressure plate not only helps maintain the water level within a reasonable range but also reduces excessive floating of down garments during washing, preventing excessive shaking or agitation of the down, thereby reducing the risk of damage to the garments.

[0046] The present invention is further configured to calculate the target water level based on the weight of the down garments to be washed, and to perform staged water level control according to a preset water level control algorithm based on the target water level, including:

[0047] The load capacity is calculated based on the weight of the down garments to be washed, and the target water level is calculated based on the load capacity. The invention is further configured such that the load capacity is calculated using the logic: Lode = m·k, where Lode is the load capacity, m is the weight of the down garments to be washed, and k is the water absorption coefficient of the down garments to be washed; the target water level is calculated using the logic: Among them, H tar Here, S represents the target water level, S is the cross-sectional area of ​​the washing machine drum, and ρ is the density of water. Specifically, the load capacity refers to the total amount of water required for the washing of down garments. This amount of water is not only related to the weight of the garments but also affected by the water absorption coefficient of the down garments. The water absorption coefficient refers to the amount of water required per unit mass of down garments when soaked in water; it has no unit. For down garments, the water absorption coefficient is usually greater than their water absorption capacity. Therefore, when calculating the load capacity, one cannot only consider their unique water absorption characteristics but also the amount of water needed for washing. This value is a pre-set empirical value. By calculating the load capacity based on the weight and water absorption coefficient of the down garments, the amount of water required during the washing process can be accurately estimated, avoiding water waste and incomplete washing due to insufficient water. By calculating the target water level based on the load capacity, the water level during the washing process can be precisely controlled, thereby ensuring the washing effect. In the washing process of down garments, an appropriate water level is crucial, ensuring that the garments are fully soaked without wasting excessive water.

[0048] The target water level with a preset ratio is set as the initial stage. The instantaneous change rate of water release volume and the cumulative water release volume at time t in the initial stage are obtained, and water is released until the water level of the initial stage is reached. The invention is further configured such that the calculation logic for the instantaneous change rate of water release volume at time t in the initial stage is as follows: in, Let be the instantaneous rate of change of water discharge at time t, C1 be the initial flow velocity adjustment factor, and k1 be the time decay coefficient; the calculation logic for the cumulative water discharge in the initial stage is as follows: Where W1 represents the cumulative water discharge in the initial stage, and T1 represents the duration of the initial stage; specifically, in the initial stage, the water level change is achieved by adjusting the water flow rate. The goal is to gradually adjust the water level from the initial state to the target water level. The initial flow rate adjustment factor C1 controls the water discharge rate in the initial stage. Typically, the initial water discharge rate is higher to quickly start the washing process. The initial flow rate adjustment factor is adjusted according to the specific specifications of the washing machine and washing requirements, and is a pre-set empirical value; in a feasible embodiment of the present invention, when the water discharge volume of the water source connected to the washing machine is less than the required water discharge volume, water is discharged according to the water discharge volume of the water source connected to the washing machine; the time decay coefficient k1 represents the gradual slowing down during the water discharge process. As the water level changes, the water discharge rate will gradually decrease. By adjusting the time decay coefficient, it is possible to effectively avoid water discharge that is too fast, resulting in excessively high water levels or overflow. The value range is [0.01, 0.1], and the specific value depends on the design of the washing machine and the accuracy of water level control. By accurately calculating the instantaneous change rate and cumulative water discharge volume, fine control of the water level can be achieved during the washing process of the washing machine. Using a combination of initial flow rate adjustment factor and time decay coefficient helps ensure that the water level gradually reaches the preset target, avoiding excessive water level fluctuations while achieving high water efficiency. Precise control of this process is particularly important for washing down garments, not only improving washing results but also protecting the garments from damage caused by excessively high or low water levels.

[0049] Upon entering the transition phase, the current water level is obtained, and the water release volume is calculated based on the current water level to release water until the target water level is reached. The invention is further configured such that the calculation logic for the current water level is: H(t) = X·H tar +C2·ln(1+k2t), where H(t) is the water level height at time t during the transition phase, X is the preset ratio, C2 is the water level growth factor, and k2 is the slow increase factor used to control the rate of water level rise; the calculation logic for the current water release is as follows: Where Q(t) is the water discharge at time t during the transition phase. Specifically, the preset ratio X controls the ratio between the initial water level and the target water level during the transition phase. Its value range is [0,1], used to set the initial water level position according to requirements. The water level increase factor C2 controls the rate of water level rise, determining the transition speed from the initial stage to the target water level. By adjusting C2, a smooth water level transition can be ensured, avoiding damage to equipment or clothing due to excessively rapid water level rise. Its value range is usually set to [0.001, 0.05]. The slow increase factor k2 further controls the gradual change in the increase during the water level rise, ensuring that the water level increase is not too rapid. As time progresses, k2 makes the water level gradually approach the target water level faster, thus achieving a smooth transition during the transition phase. Its value range is [0.01, 0.1]. By accurately calculating the water level height and water discharge during the transition phase, a smooth water level transition during the washing process can be ensured, avoiding excessively rapid water level changes or unnecessary water waste. Precise water level control not only improves washing efficiency but also protects down garments from damage, resulting in a more efficient and safer washing experience.

[0050] The present invention is further configured to, upon reaching the target water level, control the rotation speed of the impeller according to a preset impeller control algorithm to wash down garments, including:

[0051] Upon reaching the target water level, the system enters a low-speed wash cycle, smoothly accelerating to a low washing speed to ensure initial wetting and even distribution of moisture in down garments. The invention is further configured such that the smooth acceleration to a low washing speed is calculated using the following logic: Where ω1(t) is the rotational speed at time t during low-speed washing, ω min τ represents the low-speed washing rotation speed, and τ is the acceleration time constant used to control the smoothness of acceleration. Specifically, in order to smoothly accelerate to the low-speed washing rotation speed when reaching the target water level, and to avoid uneven washing or damage to down garments due to sudden changes in rotation speed, the acceleration process can be controlled using exponential smoothing acceleration. The acceleration time constant τ controls the time from the lowest rotation speed to the target washing rotation speed, and has an important smoothing acceleration effect. The smoothness of the acceleration process directly affects the treatment effect of down garments and the uniform distribution of the garments, and its value range is [5, 30].

[0052] After reaching the low-speed washing spindle speed, the system continues washing at low speed until the designated low-speed washing time is reached. Then, an accelerated washing cycle is initiated, smoothly accelerating to a stable washing spindle speed for a sustained wash. The calculation logic for this smooth acceleration to a stable washing spindle speed is: ω2(t)=ω min +(ω sta -ω min )·(1-e -γt ), where ω2(t) is the rotational speed at time t during steady-state washing, ω staTo stabilize the washing speed, γ is the acceleration coefficient, used to adjust the rate of speed increase. Specifically, during the speed acceleration phase from low-speed washing to stable washing, it is necessary to ensure that down garments gradually adapt to higher speeds to improve washing efficiency while avoiding damage caused by excessively drastic speed changes. This acceleration process can be controlled by a smooth acceleration formula, allowing the speed to gradually transition to the target stable washing speed. The acceleration coefficient γ determines the speed of the acceleration process and affects the transition time from low-speed washing to stable washing speed. A larger acceleration coefficient results in a faster acceleration process, while a smaller coefficient results in a smoother acceleration process. The acceleration coefficient is selected to balance washing performance and garment protection, with a value range of [0.01, 0.1].

[0053] The present invention is further configured to adjust the rotational speed of the impeller according to a preset dehydration control algorithm to execute the dehydration process, including:

[0054] The target spin speed for dehydration is calculated based on the load capacity and target dehydration coefficient of down-filled garments; the present invention is further configured such that the calculation logic for the target spin speed is as follows: Where, ω dehydrate ω is the target rotational speed for dehydration. max The maximum rotational speed is given by δ, where δ is the target dehydration coefficient, and Lode is the reference value. max For maximum load, α is an adjustment constant used to determine the impact of load on spin speed. Specifically, the target dehydration coefficient δ is used to adjust the degree of influence of load on spin speed, with a value range of [0,1]. The larger the value of the target dehydration coefficient δ, the greater the intensity of dehydration required for the clothes. When the load increases, the target spin speed increases more significantly. The adjustment constant α is used to adjust the impact of load on spin speed calculation, and is usually used to fine-tune the spin speed range in the formula according to different washing machine models or specific washing needs. The value of the adjustment constant α can be adjusted according to actual application or manufacturer design, with a value range of [0.8,1.2]. By calculating the spin speed based on the load and the target dehydration coefficient, the dehydration effect under different load conditions during washing can be ensured. A larger load will increase the spin speed, providing stronger centrifugal force to remove more water.

[0055] The process smoothly accelerates to the target spin speed and continues spinning until the target dehydration coefficient is reached, at which point the dehydration process ends. Specifically, after calculating the target spin speed, the process smoothly accelerates to that speed. The goal is to dehydrate down garments at an appropriate speed until the set target dehydration coefficient is achieved. During the dehydration stage, the amount of water removed is related to the spin speed, time, and the target dehydration coefficient. The amount of water removed is calculated based on the current spin speed and the absorbency coefficient of the down garment. The set target dehydration coefficient δ represents the desired water removal ratio, and the dehydration process ends once the target dehydration coefficient is reached. The target dehydration coefficient is preset based on the characteristics of down garments and washing requirements; once the water removal reaches this set ratio, the dehydration process ends. This smooth acceleration method avoids damage to down garments caused by excessively high instantaneous spin speeds. The gentle acceleration process ensures effective dehydration while reducing mechanical stress, especially for fragile down garments. By adjusting the load, dehydration coefficient, and acceleration time constant, efficient and uniform dehydration can be achieved, ensuring that down garments can remove sufficient moisture in a short time and improving work efficiency.

[0056] This invention is further configured to acquire the weight of the down garments to be washed by installing a weight sensor at the bottom of the washing machine drum, and to acquire the water level by installing a water level sensor inside the washing machine drum. Specifically, in order to accurately control the washing and spin-drying processes and ensure that the down garments are properly treated at different stages, the washing machine acquires real-time data through two key sensors: a weight sensor and a water level sensor. The combination of these two sensors allows the washing process to be intelligently adjusted according to the specific conditions of the down garments. The weight sensor at the bottom of the washing machine drum is designed to acquire the total weight of the down garments to be washed in real time; the water level sensor is usually installed on the side or bottom of the washing machine drum to monitor water level changes in real time. The function of the water level sensor is to ensure that the water level inside the washing machine is within a preset range to meet the needs of different washing modes and spin-drying. By setting up the weight sensor and the water level sensor, the washing machine can accurately control the amount of water in different washing modes to ensure that the down garments are properly wetted and washed, avoiding the effects of too much or too little water.
