Description

TECHNICAL FIELD

[0001] The present application relates to the field of washing technology of pulsator washing machines, and in particular to a stirring type pulsator washing machine and a method for preventing clothes from winding around a stirring rod. BACKGROUND

[0002] Washing machines can be divided into pulsator washing machines and drum washing machines. Among them, the barrel of the pulsator washing machine is arranged vertically to the ground. In the process of washing clothes by using the pulsator washing machine, the water flow can be driven to move by the forward or reverse rotation of the wave disc arranged at the bottom of the barrel. In this way, the moving water flow drives the clothes to overturn, so that the clothes between them and the clothes and the barrel wall rub and realize the removal of stains under the action of the detergent.

[0003] The model of the pulsator washing machine can be divided into two types of pulsator type and stirring type. In the stirring type pulsator washing machine, because the clothes will overturn during the washing process through the stirring of the stirring rod, the problem of clothes winding around the stirring rod is prone to occur during the continuous overturning process. Once the clothes wind around the stirring rod, the rotation of the stirring rod will be hindered, and the clothes are also not easy to separate from the stirring rod, so as to affect the washing effect of the clothes, and the clothes will also be worn to different degrees, which will also affect the cleanliness of the clothes. At the same time, after the clothes wind around the stirring rod, because the weight of most clothes will be concentrated on one side, the problem of eccentricity is prone to occur. When the eccentricity occurs, the dewatering function of the clothes will be affected, which will cause the clothes to be unable to dewater normally, and will also affect the user experience.

[0004] In order not to affect the cleanliness of the clothes and make the clothes separate from the stirring rod, in some embodiments, the following ways can be improved. For example, in a feasible implementation, the structure of the stirring rod can be improved, but changing the structure of the stirring rod needs to invest a lot of manpower and time, so it may not be realized in a short time. In another feasible implementation, the water flow rate and impact force can be reduced, so as to reduce the phenomenon of clothes winding around the stirring rod by reducing the washing intensity of the clothes. However, while reducing the water flow intensity and the washing intensity of the clothes, the cleaning ability of the clothes will also be reduced, that is, the cleanliness of the clothes will be affected. In yet another feasible implementation, the clothes can be subjected to a deviation correction and scattering action, but once the clothes are wound around the stirring rod for a long time or too many clothes are wound around the stirring rod, the deviation correction and scattering action will not be implemented, that is, the action will not work. Therefore, when washing clothes by using the stirring type pulsator washing machine, the problem of clothes winding around the stirring rod will also occur, which will affect the washing effect of the clothes. SUMMARY

[0005] Some embodiments of the present application provide a stirring type pulsator washing machine and a method for preventing clothes from winding around a stirring rod, so as to solve the problem of clothes winding around the stirring rod and affecting the washing effect of the clothes when washing clothes by using the stirring type pulsator washing machine.

[0050] For the purpose of making the present application and the embodiments more clear, the present application will be described in detail below with reference to the accompanying drawings of the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only some of the embodiments of the present application, but not all of the embodiments of the present application.

[0051] It should be noted that the brief description of the terms in the present application is only for the convenience of understanding the following described embodiments, and is not intended to limit the embodiments of the present application. Unless otherwise specified, these terms should be understood according to their ordinary and general meanings.

[0052] The terms "first", "second", and "third" and the like in the specification and claims of the present application and the above-described drawings are used to distinguish similar or similar objects or entities, and do not necessarily mean to limit the specific order or sequence, unless otherwise noted. It should be understood that the terms used in this way can be interchanged under appropriate circumstances.

[0053] The term "includes" and any variations thereof are intended to cover but not exclusive inclusion, for example, a product or device including a series of components does not have to be limited to all the components clearly listed, but can include other components not clearly listed or inherent to these products or devices.

[0054] A washing machine is a cleaning appliance that uses electrical energy to produce mechanical action to wash clothes. In order to save manpower, the washing machine can be used to replace the user to perform the cleaning operation. The washing machine can be divided into a pulsator washing machine and a drum washing machine. Among them, the barrel of the pulsator washing machine is arranged vertically to the ground. In the process of washing clothes by using the pulsator washing machine, the water flow can be driven to move by the wave disc arranged at the bottom of the barrel in the forward or reverse direction. In this way, the moving water flow drives the clothes to overturn, so that the clothes between and the clothes and the barrel wall rub, and the stain removal is realized under the action of the detergent.

[0055] The washing machine can be divided into two types: pulsator type and agitator type. The two types of washing machines can be distinguished by the shape of the agitator in the tub. For example, the agitator of the agitator type washing machine is provided with an agitator rod with a certain height, while the pulsator type washing machine is not provided with the agitator rod. In the agitator type washing machine, the clothes are turned over by the agitation of the agitator rod during the washing process. During the turning process, the clothes are prone to be entangled with the agitator rod. Once the clothes are entangled with the agitator rod, the rotation of the agitator rod will be hindered, and the clothes are not easy to be separated from the agitator rod, thus affecting the washing effect of the clothes and causing different degrees of wear and tear of the clothes, which will affect the cleanliness of the clothes. At the same time, when the clothes are entangled with the agitator rod, the weight of most clothes will be concentrated on one side, which is prone to cause eccentricity. When the eccentricity occurs, the clothes will not be properly dehydrated, which will affect the user experience.

[0056] In order to not affect the cleanliness of the clothes and separate the clothes from the agitator rod, in some embodiments, the following methods can be used for improvement. For example, in one possible implementation, the structure of the agitator rod can be improved. However, changing the structure of the agitator rod requires a lot of manpower and time, so it may not be realized in a short time. In another possible implementation, the water flow rate and impact force can be reduced, so as to reduce the phenomenon of clothes entangled with the agitator rod by reducing the washing intensity of the clothes. However, when the water flow rate and the washing intensity of the clothes are reduced, the cleaning ability of the clothes will also be reduced, that is, the cleanliness of the clothes will be affected. In yet another possible implementation, the clothes can be subjected to a deviation correction and scattering action. However, once the clothes are entangled with the agitator rod for a long time or too many clothes are entangled with the agitator rod, the deviation correction and scattering action will not be implemented, that is, the action will not work. Therefore, when the clothes are washed by the agitator type washing machine, the problem of clothes entangled with the agitator rod will still occur, which will affect the washing effect of the clothes.

[0057] In order to solve the problem of clothes entangled with the agitator rod and affecting the washing effect of the clothes when the clothes are washed by the agitator type washing machine, the present application provides an agitator type washing machine 100. Figure 1 The structure diagram of the agitator type washing machine 100 provided by some embodiments of the present application is shown in Figure 1 As shown in the figure, the agitator type washing machine 100 can include an agitator rod 110 and a processor 120. The agitator rod 110 can rotate clockwise or counterclockwise when performing a washing process, and the processor 120 can control the rotation of the agitator rod 110 by running program instructions to perform a washing process. The agitator type washing machine 100 can not only solve the problem of clothes entangled with the agitator rod, but also does not need to increase other structural devices and does not need to reduce the washing intensity of the washing process. Therefore, the problem of clothes entangled with the agitator rod and affecting the washing effect of the clothes can be solved without affecting the cleanliness of the clothes by the washing machine.

[0058] To facilitate understanding of the technical solutions in some embodiments of this application, the steps are described in detail below with reference to some specific embodiments and accompanying drawings. Figure 2 This application provides schematic flowcharts illustrating a method for preventing clothes from tangling in the agitator of a washing machine, as shown in some embodiments. Figure 2 As shown, when the agitator washing machine 100 performs the method of preventing clothes from tangling with the agitator rod, it may include the following steps S1-S4, the specific contents of which are as follows:

[0059] Step S1: Detect the motor pulse signal inside the washing machine.

[0060] In some embodiments, after the agitator washing machine 100 is started, the motor pulse signal inside the washing machine can be detected. The motor pulse signal is negatively correlated with the weight of the clothes inside the washing machine. The weight of the clothes can be obtained using a fuzzy weighing method. In some embodiments, the fuzzy weighing test principle is to detect the motor pulse signal in the washing machine. If there are too many clothes in the washing machine or the rotation encounters great resistance, the pulse signal will weaken. Theoretically, when clothes are entangled in the agitator, the pulse signal will weaken; that is, the weight of the clothes will affect the pulse signal.

[0061] Step S2: Determine the load level of the clothing based on its weight.

[0062] After obtaining the weight of the clothes, the agitator-type pulsator washing machine 100 can determine the load level of the clothes based on the weight. For example, it can determine whether it is a light load, a medium load, or a heavy load, thereby determining the washing method to prevent tangling. In some embodiments, the load level of the clothes can be determined by the following method: First, the agitator-type pulsator washing machine 100 can compare the weight with a load weight threshold of the clothes. If the weight is less than the load weight threshold, the load level can be determined as a first load level, which can be a light load level. If the weight is greater than or equal to the load weight threshold, the load level can be determined as a second load level, which can be a medium or heavy load level.

[0063] Step S3: If the load level is the first load level, execute the washing and spin-drying functions.

[0064] After performing fuzzy weighing judgment, the agitator washing machine 100 can determine the load level of the clothes. In some embodiments, if the load level is the first load level, such as a lower load level, the clothes are less likely to get tangled in the agitator rod 110, and the washing and spin-drying functions can be performed.

[0065] Step S4: If the load level is the second load level, determine the winding weight threshold based on the motor pulse signal, and compare the weight with the winding weight threshold during the washing process; detect that the weight is less than the winding weight threshold, determine the washing direction of the stirring rod stirring water flow, and determine the washing time in the direction opposite to the washing direction according to the washing direction to make the clothes separate from the stirring rod.

[0066] The weight of the clothes will affect the pulse signal, and the pulse signal will affect the winding weight threshold. In some embodiments, when determining the winding weight threshold, first after the motor pulse signal is collected, the motor pulse signal can be converted into the winding weight threshold. The motor pulse signal can be understood as an original value about weight, and then converted into the winding weight threshold.

[0067] When determining whether the clothes are wound around the stirring rod 110, the following method can be used for determination. First, the comparison result of the weight and the winding weight threshold during the washing process can be obtained, if the comparison result is that the weight is less than the winding weight threshold, it can be determined that the clothes are wound around the stirring rod; if the comparison result is that the weight is greater than or equal to the winding weight threshold, it can be determined that the clothes are not wound around the stirring rod. The winding weight threshold can be determined according to the actual needs combined with the strength of the pulse signal, which is not limited in the present application.

[0068] Figure 3 The flowchart provided by some embodiments of the present application for executing different processing procedures according to the comparison result of the weight and the winding weight threshold is shown in FIG. 8. In some embodiments, when the comparison result of the weight and the winding weight threshold is obtained, if it is determined that the clothes are wound around the stirring rod 110, the agitator impeller washing machine 100 can execute the anti-winding washing process. If it is determined that the clothes are not wound around the stirring rod 110, the agitator impeller washing machine 100 can execute the washing function and the dehydration function, i.e. execute the normal washing process. Figure 3

[0069] For example, after the winding weight threshold is set, the fuzzy weighing judgment is performed simultaneously when the washing starts. If the weight of the clothes is less than the given winding weight threshold, it can be considered that winding has started, and the anti-winding washing process is started.

[0070] ​In some embodiments, the anti-tangling washing process may include the following: When performing the anti-tangling washing process, the washing direction of the water flow stirred by the agitator 110 can be determined first, and the washing time in the opposite direction can be determined based on the washing direction. For example, the washing time in the opposite direction can be determined as follows: The agitator-type pulsator washing machine 100 first obtains the washing direction, which includes clockwise and counterclockwise directions. If the washing direction is clockwise, the reverse direction of the agitator 110 can be determined to be counterclockwise, and the agitator 110 can be controlled to rotate counterclockwise for a first preset time; if the washing direction is counterclockwise, the reverse direction of the agitator 110 can be determined to be clockwise, and the agitator 110 can be controlled to rotate clockwise for a second preset time. The first and second preset times can be set according to actual needs, for example, they can be determined based on factors such as the degree of tangling of clothes, the number of clothes, and the weight of the clothes.

[0071] In other words, after the agitator-type pulsator washing machine 100 distinguishes whether the washing process is clockwise or counterclockwise, it can implement different measures to prevent the agitator rod 110 from tangling according to the washing direction. Compared with the correction action when the clothes are off-center, this method can solve the problem of clothes tangling by rotating in both directions without adding other structural components, thereby reducing wear between clothes and solving the problem of clothes tangling with the agitator rod and affecting the washing effect when washing clothes in an agitator-type pulsator washing machine.

[0072] After determining the reverse direction and rotation duration of the agitator 110, the agitator-type pulsator washing machine 100 can control the agitator 110 to rotate in the reverse direction, so that the clothes are detached from the agitator 110. This process is repeated until the weight of the clothes meets the normal washing standard when weighed, at which point the anti-tangling washing process is no longer required.

[0073] Figure 4 A flowchart illustrating the process of determining the number of water flow groups in a pulsator washing machine according to some embodiments of this application is shown below. Figure 4 As shown, in some embodiments, the agitator-type pulsator washing machine 100 can determine the number of water flow groups by the total washing time and the duration of each water flow group. The agitator-type pulsator washing machine 100 can first obtain the total washing time T, then obtain the group washing time t of a group of water flows, and finally determine the number of water flow groups N based on the ratio of the total washing time T to the group washing time t.

[0074] In some embodiments, since the washing time of the agitator washing machine 100 is fixed, the washing time is determined by the number of water flow groups, and thus the number of water flow groups is also fixed. After determining the number of water flow groups, the length of time of the forward rotation and the reverse rotation of the stirring rod 110 can be determined by the number of water flow groups. For example, the first preset length of time and the second preset length of time are determined by the total number of water flow groups and the current washing direction, that is, the forward rotation and the reverse rotation of the stirring rod 110 are determined.

[0075] From the above technical solutions, it can be seen that the above embodiments provide an agitator washing machine, which detects a motor pulse signal in the washing machine; the motor pulse signal is negatively related to the weight of clothes in the washing machine; a load level of the clothes is determined according to the weight; if the load level is a first load level, a washing function and a dehydration function are performed; if the load level is a second load level, a winding weight threshold is determined based on the motor pulse signal, and the weight is compared with the winding weight threshold in a washing process; when it is detected that the weight is less than the winding weight threshold, a washing direction of stirring water flow by the stirring rod is determined, and a washing time in a direction opposite to the washing direction is determined according to the washing direction, so that the clothes are separated from the stirring rod. The agitator washing machine can perform fuzzy weighing throughout the washing process to monitor whether the winding phenomenon occurs in real time, and can perform a winding prevention washing process when the winding phenomenon occurs, effectively solving the problem of clothes winding around the stirring rod. The agitator washing machine can solve the problem of clothes winding around the stirring rod, without the need to increase other structural devices or reduce the washing strength of cleaning. Therefore, while not affecting the cleanliness of the clothes by the washing machine, the problem of clothes winding around the stirring rod and affecting the cleaning effect of the clothes can be solved.
