Description

Technical Field

[0001] This invention belongs to the technical field of clothing processing equipment, specifically, it relates to a clothing processing method for a washing machine and a washing machine. Background Technology

[0002] A washing machine is a cleaning appliance that uses electrical energy to generate mechanical energy to wash clothes. Currently, the market penetration rate of washing machines in my country has exceeded 76%, with over 96% in urban areas and over 53% in rural areas. Users often find that after washing clothes using the program selected on the washing machine's control panel, a strong detergent or washing powder smell is present when the door is opened to hang them to dry, and there is a significant amount of detergent residue. This is mainly because users, worried about insufficient washing results, manually add too much detergent, or due to other non-human factors. Users adding too much detergent manually due to concerns about washing results, or other non-human factors, leads to excessive detergent residue after washing. This is especially true for larger and thicker garments, where detergent residue is relatively higher. Alternatively, during high-speed spin-drying, severe tangling of clothes can prevent effective rinsing in some areas, resulting in more residue. Excessive residue may cause clothes to become stiff and even irritate the skin, especially sensitive skin.

[0003] Chinese patent application number CN201010115250.1 discloses a washing machine, including a washing and spin-drying tub, a rotating blade disposed at the inner bottom of the washing and spin-drying tub, a drive unit and a control unit for driving the washing and spin-drying tub and the rotating blade; the control unit drives the rotating blade to continuously reverse in the left and right directions by rotating it at different speeds to the left and right, thereby generating changes in the position of the laundry and tumbling the laundry up and down, improving washing performance. Although this also reduces detergent residue and uneven washing, its indiscriminate direct changes in position and tumbling motions waste potentially unnecessary electrical energy and may prolong washing time, reducing the user experience. Therefore, there is a need for a method of selectively changing the position and tumbling the laundry.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a method for handling clothes in a washing machine and a washing machine. When the washing machine executes the washing program, it intelligently selects whether to add a shaking treatment step before the rinsing step by judging the load parameters such as the weight and / or volume of the clothes. This allows the clothes to be fully unfolded before rinsing even when the washing load is large, thereby fully rinsing out the detergent residue in the clothes and solving the technical problems of incomplete rinsing and indiscriminate shaking treatment.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0007] A method for handling clothes in a washing machine includes: starting a washing program and obtaining load parameters of the clothes to be handled;

[0008] If it is determined that the load parameter of the garment to be processed is greater than a preset threshold, a shaking process is added before the rinsing step of the washing program.

[0009] Furthermore, the washing process includes a washing stage, a rinsing stage, and a final dehydration stage.

[0010] Preferably, the washing stage includes a washing and dehydration step, and the shaking and loosening treatment step is performed after the washing and dehydration step is completed and before entering the rinsing stage.

[0011] Furthermore, the rinsing stage includes multiple rinsings, and each rinsing except for the last rinsing includes a rinsing and dehydration step;

[0012] The shaking and loosening process is performed after each rinsing and dehydration step and before the next rinsing.

[0013] Furthermore, the shaking parameters of the shaking processing step are determined based on the difference between the obtained load parameters of the clothing to be processed and the preset threshold.

[0014] Furthermore, the jitter parameters include one or more of the following: jitter duration, jitter rotation speed, jitter direction, and jitter pause time.

[0015] Furthermore, when it is determined that the difference between the load parameter of the garment to be processed and the preset threshold is less than or equal to the preset difference, the shaking duration of the shaking processing step is time T1.

[0016] When it is determined that the difference between the load parameter of the garment to be processed and the preset threshold is greater than the preset difference, the shaking time of the shaking processing step is increased to time T2, where T2 > T1.

[0017] Furthermore, when the difference ΔW between the load parameter W1 of the garment to be processed and the preset threshold W0 is greater than the preset difference ΔW': for each increase of the difference ΔW by the preset difference ΔW', the shaking duration is increased by Δt time on the basis of the time T1, that is, the shaking duration T=T1+(W1-W0) / ΔW'×Δt.

[0018] Furthermore, the shaking process also includes a shaking method, which includes at least alternating clockwise and counterclockwise rotation;

[0019] Preferably, when the difference between the load parameter of the garment to be processed and the preset threshold is less than or equal to the preset difference, the number of cycles of alternating rotation is at least N times; the rotation speed of clockwise rotation is the same as the rotation speed of counterclockwise rotation.

[0020] When it is determined that the difference between the load parameter of the garment to be processed and the preset threshold is greater than the preset difference, the number of cycles of the alternating rotation is at least M times, where M > N; the rotation speeds of the clockwise rotation and the counterclockwise rotation are different.

[0021] Furthermore, the load parameters include at least weight parameters and / or volume parameters.

[0022] Furthermore, another objective of the present invention is to provide a washing machine that uses the above-described washing machine method for clothing handling.

[0023] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0024] 1. The washing machine provided by the present invention intelligently selects whether to add a shaking treatment step before the rinsing step by judging load parameters such as the weight and / or volume of the clothes when executing the washing program. This allows the clothes to be fully unfolded before rinsing even when the washing load is large, thereby fully rinsing out the detergent residue in the clothes, improving the cleanliness of the clothes and the user experience.

[0025] 2. This invention further limits the running time of the shaking process by determining whether the difference between the load parameters of the clothing to be processed and a preset threshold is greater than a preset difference. Different shaking processes are performed on clothing of different weight ranges for different running times, thereby maximizing energy saving and saving program running time.

[0026] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0030] It should be noted that these accompanying drawings and textual descriptions are not intended to limit the scope of the invention in any way, but rather to illustrate the concept of the invention to those skilled in the art by referring to specific embodiments. Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0032] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0033] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0034] The present invention will be further described in detail below with reference to the embodiments.

[0035] like Figure 1 and 2As shown, the washing machine's clothing processing method in this embodiment includes starting a washing program and obtaining the load parameters of the clothes to be processed; if it is determined that the load parameters of the clothes to be processed are greater than a preset threshold, a shaking processing step is added before the rinsing step of the washing program; if it is determined that the load parameters of the clothes to be processed are less than or equal to the preset threshold, a normal washing program is executed.

[0036] The decision to add a shaking process is made only when the weight of the clothes to be washed reaches a certain threshold. When there are many clothes to be washed, the shaking process is initiated to loosen the clothing fibers and make the clothes fluffy. The shaken clothes are more likely to have residual detergent dissolved from the clothing fibers during rinsing, which is more conducive to cleaning the clothes.

[0037] For laundry that has not reached the preset threshold, since it is lightweight and has few items, it can still achieve a high level of cleanliness after rinsing with water. Therefore, in order to save energy and reduce the running time of the program, the shaking and scattering process can be omitted.

[0038] Regarding the setting of the preset threshold, at least the washing capacity of the washing machine should be taken into account. For example, for an 8 kg washing machine, the preset threshold can be 6. When the amount of laundry is 5 kg, since there are fewer clothes, the regular washing mode can be used directly. However, when the amount of laundry is 7.6 kg, since there are more clothes and the preset threshold is exceeded, the washing machine's control system will add a shaking process to make the clothes rinse more thoroughly and minimize the amount of detergent residue.

[0039] Furthermore, the washing process includes a washing stage, a rinsing stage, and a final dehydration stage.

[0040] Preferably, the washing stage includes a washing and dehydration step, and the shaking and loosening treatment step is performed after the washing and dehydration step is completed and before entering the rinsing stage.

[0041] In the later stages of the washing process, after draining and dehydrating, the dehydrated clothes are shaken to loosen them. During the rinsing stage, the clothes are allowed to fully contact with clean water, resulting in a better rinsing effect.

[0042] Furthermore, the rinsing stage includes multiple rinsings, and each rinsing except for the last rinsing includes a rinsing and dehydration step; after each rinsing and dehydration step and before the next rinsing, the shaking and dispersing treatment step is performed.

[0043] Specifically, when the weight of the clothes to be processed exceeds the preset threshold, the washing machine automatically changes the washing program, adding a shaking process after each spin-drying cycle in the entire washing process. The shaking process is not required after the last spin-drying cycle. Shaking after each spin-drying cycle helps residual detergent dissolve in the clothing fibers, resulting in cleaner clothes. The shaking process is not required after the last spin-drying cycle because the user directly hangs the clothes to dry, so it is unnecessary.

[0044] Furthermore, the shaking parameters of the shaking processing step are determined based on the difference between the obtained load parameters of the clothing to be processed and the preset threshold.

[0045] Furthermore, the jitter parameters include one or more of the following: jitter duration, jitter rotation speed, jitter direction, and jitter pause time. It is understood that the jitter parameters are not limited to the above parameters, and are not specified here.

[0046] Furthermore, the load parameters include at least weight parameters and / or volume parameters.

[0047] Furthermore, when it is determined that the difference between the load parameter of the garment to be processed and the preset threshold is less than or equal to the preset difference, the shaking time of the shaking processing step is T1 time; for example, if the load parameter is 7.5Kg, the preset threshold is 7Kg, and the preset difference is 1Kg, we can obtain 7.5-7=0.5<1, that is, the shaking time is T1s (seconds).

[0048] When it is determined that the difference between the load parameter of the garment to be processed and the preset threshold is greater than the preset difference, the shaking time of the shaking processing step is increased to time T2, where T2 > T1.

[0049] like Figure 2 As shown, further, when the difference ΔW between the load parameter W1 of the garment to be processed and the preset threshold W0 is greater than the preset difference ΔW': for each increase of the difference ΔW by the preset difference ΔW', the shaking duration is increased by Δt time based on the T1 time, i.e., the shaking duration T = T1 + (W1 - W0) / ΔW' × Δt. Specifically, the load parameter W1 is 7.5Kg, the preset threshold W0 is 5Kg, and the preset difference ΔW' is 1Kg, which yields 7.5 - 5 = 2.5 > 1, where 2.5 is the difference ΔW, 2.5 / 1 = 2.5, and Δt is 2s, the shaking duration T = T1 + 2.5 / 1 × 2 = (T1 + 5)s. It should be understood that this shaking duration is the total time for one shaking processing step, and the time for specific steps needs to be set according to the shaking parameters.

[0050] Furthermore, the shaking process also includes a shaking method, which includes at least alternating clockwise and counterclockwise rotation.

[0051] Preferably, when the difference between the load parameter of the garment to be processed and the preset threshold is less than or equal to the preset difference, the number of alternating rotation cycles is at least N times; the rotation speed of the clockwise rotation is the same as that of the counterclockwise rotation; specifically, clockwise rotation plus counterclockwise rotation constitutes one alternating rotation cycle, and when the difference is less than or equal to the preset difference, the number of alternating rotation cycles is at least 3 times; the rotation speed of the clockwise rotation and the rotation speed of the counterclockwise rotation can both be 45 rpm.

[0052] When the difference between the load parameter of the garment to be processed and the preset threshold is greater than the preset difference, the number of cycles of alternating rotation is at least M, where M > N; the clockwise rotation and the counterclockwise rotation have different speeds; specifically, when the difference is greater than the preset difference, the number of cycles of alternating rotation is at least 5; the clockwise rotation speed is 60 rpm and the counterclockwise rotation speed is 50 rpm; or the clockwise rotation speed is 50 rpm and the counterclockwise rotation speed is 60 rpm.

[0053] Furthermore, another objective of the present invention is to provide a washing machine that uses the above-described washing machine method for clothing handling.

[0054] Example 1

[0055] In this embodiment, the washing machine controlling the clothing processing method is a drum washing machine, such as... Figure 1 As shown, the clothes handling method of the drum washing machine in this embodiment includes starting the washing program and obtaining the weight of the clothes to be processed; if it is determined that the weight of the clothes to be processed is greater than a preset weight, a shaking process is added before the rinsing step of the washing program; if it is determined that the weight of the clothes to be processed is less than or equal to the preset weight, the normal washing program is executed.

[0056] When the weight of the laundry reaches a certain threshold, the washing program will automatically initiate a shaking process. When there are many clothes to be washed, this shaking process loosens the fabric fibers, making the clothes more fluffy. This loosened fabric allows residual detergent to dissolve more easily during rinsing, resulting in a cleaner wash. When the weight of the laundry is less than the preset weight, due to the lighter weight and fewer clothes, the shaking process can be omitted to save energy and reduce program running time. Of course, for better rinsing results, the shaking process can be manually added.

[0057] Furthermore, the washing process includes a washing stage, a rinsing stage, and a final dehydration stage. Preferably, the washing stage includes a washing and dehydration step, and the shaking and scattering treatment step is performed after the washing and dehydration step and before entering the rinsing stage.

[0058] In the later stages of the washing process, after draining and dehydrating, the dehydrated clothes are shaken to loosen them. During the rinsing stage, the clothes are allowed to fully contact with clean water, resulting in a better rinsing effect.

[0059] Furthermore, the rinsing stage includes multiple rinsings, each of which includes a rinsing and dehydration step; after each rinsing and dehydration step and before proceeding to the next rinsing, the shaking and dispersing process is performed.

[0060] Specifically, when the weight of the clothes to be processed exceeds the preset weight, the washing machine automatically changes the washing program, adding a shaking process after each spin-drying cycle in the entire washing process, and adding a shaking process after the last spin-drying cycle to facilitate the user's drying of the washed clothes. Shaking after each spin-drying cycle helps residual detergent dissolve in the clothing fibers, resulting in cleaner clothes. From an energy-saving perspective, the shaking process can be omitted after the last spin-drying cycle; this can be customized according to individual settings.

[0061] Furthermore, the shaking parameters of the shaking process are determined based on the difference between the obtained weight of the clothing to be processed and the preset weight.

[0062] like Figure 2 As shown, the shaking parameters further include one or more of the following: shaking duration, shaking speed, shaking direction, and shaking pause time. When it is determined that the difference between the weight of the garment to be processed and the preset weight is less than or equal to the preset difference, the shaking duration of the shaking processing step is 60 seconds; for example, if the garment to be processed weighs 7.5 kg, the preset weight is 7 kg, and the preset difference is 1 kg, then 7.5 - 7 = 2.5 < 1, meaning the shaking duration is 60 seconds.

[0063] When the difference between the weight of the garment to be processed and the preset weight is greater than a preset difference, the shaking time of the shaking process is increased to time T2, where T2 > 30s. Specifically, for each increment of the preset difference ΔW' by the difference ΔW, the shaking time is increased by Δt time on top of the time T1, i.e., shaking time T = T1 + (W1 - W0) / ΔW'. Specifically, when the weight of the garment to be processed is 7.5Kg and the preset weight is 5Kg, the difference is 7.5 - 5 = 2.5Kg. Assuming the preset difference ΔW' is 1Kg and Δt is 2s, the total shaking time T = 60 + 2.5 / 1 × 2 = 65s.

[0064] Furthermore, the shaking process also includes a shaking method, which includes at least alternating clockwise and counterclockwise rotation.

[0065] Specifically, clockwise rotation plus counterclockwise rotation constitutes one cycle of alternating rotation. When the difference is less than or equal to a preset difference, the number of cycles of alternating rotation is at least 3. The rotation speed of both clockwise and counterclockwise rotation can be 45 rpm. More specifically, in the first cycle, the rotation is clockwise at 45 rpm for 10 seconds, paused for 3 seconds, and then counterclockwise at 45 rpm for 10 seconds. In the second cycle, the rotation is clockwise at 45 rpm for 8 seconds, paused for 2 seconds, and then counterclockwise at 45 rpm for 8 seconds. In the third cycle, the rotation is clockwise at 45 rpm for 9 seconds, paused for 1 second, and then counterclockwise at 45 rpm for 9 seconds.

[0066] When the difference is greater than a preset difference, the number of cycles of alternating rotation is at least 5; the clockwise rotation speed is 60 rpm and the counterclockwise rotation speed is 50 rpm; or the clockwise rotation speed is 50 rpm and the counterclockwise rotation speed is 60 rpm. More preferably, in the first cycle, the rotation is clockwise at 60 rpm for 7 seconds, paused for 3 seconds, and then counterclockwise at 50 rpm for 7 seconds; in the second cycle, the rotation is clockwise at 50 rpm for 6 seconds, paused for 2 seconds, and then counterclockwise at 60 rpm for 6 seconds; in the third cycle, the rotation is clockwise at 60 rpm for 5 seconds, paused for 2 seconds, and then counterclockwise at 50 rpm for 5 seconds; in the fourth cycle, the rotation is clockwise at 60 rpm for 4 seconds, paused for 1 second, and then counterclockwise at 50 rpm for 4 seconds; in the fifth cycle, the rotation is clockwise at 60 rpm for 3 seconds, paused for 2 seconds, and then counterclockwise at 50 rpm for 3 seconds; in the fifth cycle, the rotation is clockwise at 50 rpm for 2 seconds, paused for 1 second, and then counterclockwise at 60 rpm for 2 seconds.
