Description

Technical Field

[0001] This invention belongs to the field of household appliance technology, and more specifically, relates to a control method for a washing machine. Background Technology

[0002] Fully automatic washing machines generally follow a pre-set program to perform washing, rinsing, and spin-drying cycles to complete the entire washing process. With the increasing number of users of top-loading washing machines, users' personalized needs are becoming stronger, and the ability to wash down jackets in top-loading washing machines has become one of their personalized requirements. Current top-loading washing machines either fill with water to a certain level before the pulsator rotates to begin washing, or the tub and pulsator rotate slowly together to wet the load. During washing, a series of measures are taken to improve the washing effect on large items, such as increasing the motor's running time, shortening the stop time to increase the rotation-to-stop ratio and enhancing water flow, ensuring the water level is not lower than the washing level during rinsing, and increasing the amount of water used for rinsing.

[0003] To clean large items, existing washing machines have added a soaking program. However, since down jackets tend to float, the program cannot quickly and effectively soak them. This results in poor mixing of detergent and down, making it difficult for the detergent to penetrate deep into the garment. Consequently, down jackets are not cleaned properly, leading to user complaints and dissatisfaction. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a control method for a washing machine, which improves the washing effect on down jackets and enhances the user experience by adopting a mode of simultaneous water intake and washing with circulating spray during water intake.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0006] This invention provides a control method for a washing machine. When the washing machine executes the water intake program, centrifugal water is introduced into the washing machine. After the water level reaches a set low level, the washing machine is controlled to run at a set speed and a set rotation-stop ratio. Water continues to be introduced into the washing machine, and a circulating spray is run. After the water level reaches a set high level, water intake stops, and the circulating spray continues.

[0007] Furthermore, during the process of filling the water to the set low water level, the inner tub of the washing machine is controlled to rotate, or the inner tub and the impeller of the washing machine are controlled to rotate together, and the water flows into the inner tub under the action of centrifugal force.

[0008] Furthermore, during the process of filling water to the set high water level, the inner tank is controlled to stop rotating while the impeller continues to rotate. The impeller is controlled to operate in a first mode with a set high speed and low rotation-to-stop ratio, and in a second mode with a set low speed and high rotation-to-stop ratio, with the two modes alternating.

[0009] Furthermore, the impeller operates in the first mode three times and in the second mode three times, with the time spent operating in the first mode each time being longer than the time spent operating in the second mode.

[0010] Preferably, the control impeller first operates in the first mode and then in the second mode.

[0011] Furthermore, the circulating spray process includes: since there are two water channels and two filters on the drum wall, and the filters also have water outlets at the top, during the washing process, as the water level rises, the down jacket will be hit and impacted by the waterfall of water from four directions; the water flows up along the water channel between the inner and outer drums to the outer drum cover of the washing machine, and then returns to the inner drum from the outer drum cover, forming a washing water flow from top to bottom.

[0012] Furthermore, the washing machine executes a washing program, controls the pulsator to operate at a set speed and rotation-to-stop ratio, controls the pulsator to operate in a third mode with a set high speed and low rotation-to-stop ratio, and in a fourth mode with a set low speed and high rotation-to-stop ratio, with the two modes alternating.

[0013] Furthermore, the impeller runs twice in the third mode and twice in the fourth mode. The time the impeller spends running in the third mode for the first time is equal to the time it spends running in the fourth mode, and the time the impeller spends running in the third mode for the second time is less than the time it spends running in the fourth mode.

[0014] Preferably, the control impeller first operates in the third mode and then in the fourth mode.

[0015] Furthermore, the washing machine executes a rinsing program and performs multiple rinsing cycles during the rinsing process. During the first rinsing cycle, the water intake process of the water intake program and the washing process of the washing program are repeated.

[0016] Furthermore, during the second rinse, the impeller is controlled to rotate, centrifugally feeding water into the inner tub. After the water level reaches the set high level, the impeller is controlled to run at the set speed and rotation-to-stop ratio to perform the rinsing and washing. After the rinsing and washing are completed, the circulating spray is activated.

[0017] Furthermore, the control impeller operates in a fifth mode with a set high speed and low speed-to-stop ratio, and in a sixth mode with a set low speed and high speed-to-stop ratio, with the two modes alternating.

[0018] Preferably, the impeller operates once in the fifth mode and once in the sixth mode, and the time the impeller operates in the fifth mode each time is equal to the time it operates in the sixth mode;

[0019] More preferably, the control impeller first operates in the fifth mode, and then in the sixth mode;

[0020] More preferably, the second rinsing process is repeated during the third rinsing.

[0021] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0022] By using a simultaneous water intake and washing mode with circulating spray, down jackets can be quickly and effectively soaked, and the mixing effect between the down jacket and the washing machine detergent can be increased, thereby improving the washing effect of down jackets and enhancing the user experience.

[0023] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0029] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection 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.

[0030] This invention provides a control method for a washing machine. When the washing machine executes the water intake program, centrifugal water is introduced into the washing machine. After the water level reaches a set low level, the washing machine is controlled to run at a set speed and a set rotation-stop ratio. Water continues to be introduced into the washing machine, and a circulating spray is run. After the water level reaches a set high level, water intake stops, and the circulating spray continues.

[0031] In an embodiment of the present invention, the washing machine includes an outer tub and an inner tub for holding down jackets. The inner tub is rotatably disposed inside the outer tub, and the inner tub may or may not have a pulsator.

[0032] When filling the washing machine with water, first fill the machine with a set low water level. During this water filling process, the inner tub and / or impeller of the washing machine rotate, and the machine washes while filling with water. The water flows into the inner tub under the action of centrifugal force, which helps to wet the down jacket and effectively soak it. It also increases the mixing of washing water and detergent, thereby increasing the mixing of the down jacket and detergent and improving the washing effect of the down jacket.

[0033] During the process of adding water from a set low level to a set high level, the washing machine operates at a set speed and spin-stop ratio, washing while simultaneously adding water to further wet the down jacket, effectively soaking it and increasing the mixing of the washing water and detergent. Simultaneously, a circulating spray system circulates the water flow within the inner tub, spraying water from bottom to top onto the down jacket, further wetting and effectively soaking it. This allows the detergent to penetrate deeper into the garment, improving the washing effect. The set high water level is the predetermined washing water level, measured by a level gauge inside the inner tub. When the set washing water level is reached, no more water is added to the inner tub.

[0034] After the water level reaches the set high level, the machine stops filling the washing machine and continues to run the circulating spray, so that the water flow continuously hits and wets the down jacket, further effectively soaking the down jacket and improving the washing effect.

[0035] In an embodiment of the present invention, during the process of water entering to a set high water level, the inner tank is controlled to stop rotating while the impeller continues to rotate. The impeller is controlled to operate in a first mode with a set high speed and low rotation-to-stop ratio, and in a second mode with a set low speed and high rotation-to-stop ratio, with the two modes alternating.

[0036] In embodiments of the present invention, during the process of water entering from a set low water level to a set high water level, the inner tub no longer rotates, only the pulsator rotates, and the washing machine enters fully automatic mode. During this process, a combination of high speed and low spin-stop ratio and low speed and high spin-stop ratio is used. High speed is beneficial for the tumbling of the down jacket, thereby allowing the down jacket to be soaked quickly. The low spin-stop ratio at high speed helps to prevent splashing. Low speed can be used for pre-washing clothes. The high spin-stop ratio at low speed speeds up the pre-washing. The first mode and the second mode are alternated to achieve the goal of soaking the down jacket quickly while pre-washing the down jacket.

[0037] In an embodiment of the present invention, the impeller operates three times in a first mode and three times in a second mode, with the time spent operating in the first mode each time being longer than the time spent operating in the second mode.

[0038] In an embodiment of the present invention, during the process of water intake to a set high water level, the impeller operates three times in a first mode and three times in a second mode, with the following alternating operation: first time in the first mode, first time in the second mode, second time in the first mode, second time in the second mode, third time in the first mode, third time in the second mode, and so on, with the above modes operating sequentially; or, first time in the second mode, first time in the first mode, second time in the second mode, second time in the first mode, third time in the second mode, third time in the first mode, and so on, with the above modes operating sequentially.

[0039] Because down jackets produce a lot of air bubbles and become fluffy when they get wet, they tend to float on the surface and don't get completely soaked. Therefore, the time the impeller runs at a set high speed and low speed-to-stop ratio is longer than the time it runs at a set low speed and high speed-to-stop ratio. The longer the impeller runs at a set high speed and low speed-to-stop ratio, the more and faster the down jacket is turned over, thus allowing the down jacket to get soaked more quickly.

[0040] Specifically, the control impeller first operates in the first mode, then in the second mode, to quickly wet the down jacket, which is beneficial for the subsequent pre-washing of the down jacket.

[0041] In the embodiments of the present invention, the circulating spraying process includes two methods: the first method is that the inner tub wall has two water channels and two filters are provided on the inner tub wall. Each water channel has a water outlet, and the upper end of the filter also has a water outlet. The four water outlets are arranged along the circumference of the inner tub. During the washing process, as the water level rises, the down jacket will be hit and impacted by the waterfall of water from four directions.

[0042] The second method is as follows: the water flows up along the channel between the inner tub and the outer tub to the outer tub cover of the washing machine. The outer tub cover has a water outlet, and the water returns from the outer tub cover to the inner tub, forming a washing water flow from top to bottom.

[0043] During the circulating spray, either the first or the second method can be selected; preferentially, the first method is selected during the process of increasing the water level from low to high; when water is stopped entering the washing machine, the second method is selected for circulating spray.

[0044] In an embodiment of the present invention, the washing machine executes a washing program, controls the pulsator to operate at a set speed and a set rotation-to-stop ratio, controls the pulsator to operate in a third mode with a set high speed and a low rotation-to-stop ratio, and operates in a fourth mode with a set low speed and a high rotation-to-stop ratio, with the two modes alternating.

[0045] In embodiments of the present invention, after the washing machine executes the water intake program, it executes the washing program. The inner tub remains stationary, with only the pulsator rotating. During this process, a combination of high speed and low spin-stop ratio and low speed and high spin-stop ratio is used. High speed facilitates the tumbling of the down jacket, thereby allowing it to be soaked quickly. The low spin-stop ratio at high speed helps prevent splashing. Low speed washes the clothes, and the high spin-stop ratio at low speed speeds up the washing process. The third and fourth modes are alternated to achieve the goal of soaking the down jacket quickly while washing it.

[0046] In an embodiment of the present invention, the impeller operates twice in the third mode and twice in the fourth mode. The time for the impeller to operate in the third mode for the first time is equal to the time for operating in the fourth mode, and the time for the impeller to operate in the third mode for the second time is less than the time for operating in the fourth mode.

[0047] In an embodiment of the present invention, during the washing of a down jacket, the impeller operates twice in a third mode and twice in a fourth mode, alternating as follows: first third mode, first fourth mode, second third mode, second fourth mode, the above modes are operated sequentially; or, first fourth mode, first third mode, second fourth mode, second third mode, the above modes are operated sequentially.

[0048] Since the time for tumbling the down jacket has been increased during the water intake process, and the washing process needs to focus on washing, the time for the impeller to run at the set high speed and low speed-to-stop ratio for the first time is equal to the time for the impeller to run at the set low speed and high speed-to-stop ratio for the first time. The time for the impeller to run at the set high speed and low speed-to-stop ratio for the second time is less than the time for the impeller to run at the set low speed and high speed-to-stop ratio. Relatively speaking, the time for the impeller to run at the set low speed and high speed-to-stop ratio has been increased.

[0049] Specifically, the control impeller first operates in the third mode and then in the fourth mode, so that the down jacket is soaked as quickly as possible, which is beneficial for subsequent washing of the down jacket.

[0050] It should be noted that, compared to alternating between the first and second modes, the time spent in the third mode is longer than the time spent in the first mode, and the time spent in the fourth mode is greater than or equal to the time spent in the second mode. This achieves the goal of getting the down jacket wet quickly during washing while increasing the washing effect.

[0051] In embodiments of the present invention, the washing machine performs a rinsing program and performs multiple rinsing cycles during the rinsing process. During the first rinsing cycle, the water intake process of the water intake program and the washing process of the washing program are repeated.

[0052] In an embodiment of the present invention, after the washing machine completes the washing program, it performs a first spin-drying process, which takes a relatively long time. After the spin-drying is completed, a rinsing program is then performed. During the rinsing program, the down jacket is rinsed multiple times to eliminate foam on the down jacket to the greatest extent. In order to achieve rapid tumbling of the down jacket and accelerate the elimination of foam on the down jacket, the first rinsing process adopts the water intake process of the above-mentioned water intake program and the washing process of the above-mentioned washing program.

[0053] In an embodiment of the present invention, during the second rinse, the impeller is controlled to rotate to centrifugally feed water into the inner tub. After the water level reaches the set high level, the impeller is controlled to run at a set speed and rotation-to-stop ratio to perform rinsing and washing. After rinsing and washing are completed, a circulating spray is run.

[0054] In an embodiment of the present invention, after the first rinse, a second dehydration is performed. Since the down jacket has already undergone the first dehydration, the down jacket is almost free of tangles at this time. After the second dehydration, a second rinse is performed.

[0055] Since the first rinse has largely eliminated the foam on the down jacket and the down jacket is basically soaked, the time for the continuous spraying can be reduced compared to the first rinse.

[0056] In embodiments of the present invention, the control impeller operates in a fifth mode with a set high speed and low speed-to-stop ratio, and in a sixth mode with a set low speed and high speed-to-stop ratio, with the two modes alternating.

[0057] In this embodiment of the invention, during the second rinse, the inner tub remains stationary, with only the impeller rotating. A combination of high speed and low rotation-to-stop ratio and low speed and high rotation-to-stop ratio is used. High speed facilitates the tumbling of the down jacket, allowing it to be thoroughly wetted quickly. The low rotation-to-stop ratio at high speed helps prevent splashing. Low speed allows for rinsing and washing the clothes, and the high rotation-to-stop ratio at low speed accelerates the rinsing and washing process. The fifth and sixth modes alternate, achieving the goal of thoroughly wetting the down jacket while simultaneously rinsing and washing it.

[0058] Specifically, the impeller runs once in mode 5 and once in mode 6, with the time spent in mode 5 being equal to the time spent in mode 6. During the second rinse, the impeller runs once in mode 5 and once in mode 6, alternating between the following: first mode 5, first mode 6, and so on, or first mode 6, first mode 5, and so on.

[0059] Since the down jacket has been thoroughly soaked during the first rinse, the number of runs in modes 5 and 6 can be reduced during the second rinse. Water can be directly added to the set high water level, and the time the impeller runs in mode 5 can be equal to the time it runs in mode 6.

[0060] Specifically, the control impeller first runs in mode 5, then in mode 6, to further wet the down jacket before rinsing and washing.

[0061] It should be noted that after the second rinse is completed, a third spin-drying is performed. After the third spin-drying is completed, a third rinse is performed. After the third rinse is completed, a fourth spin-drying is performed. During the third rinse, the second rinse process is repeated. Since the foam on the down jacket has been largely eliminated and the down jacket is basically soaked, the third rinse only requires repeating the second rinse process.

[0062] In addition, the high-speed rotation speeds involved in the water intake program, washing program, and rinsing program are equal, the low-speed rotation speeds are equal, the high-speed stop ratio is equal, and the low-speed stop ratio is equal.

[0063] The time the pulsator takes to run in mode 5 is equal to the time it takes to run in mode 1, and less than the time it takes to run in mode 3; the time the pulsator takes to run in mode 6 is less than the time it takes to run in mode 2, and less than the time it takes to run in mode 4.
