Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of washing machines, in particular to a pulsator assembly and a washing machine. BACKGROUND

[0002] The main washing components of a pulsator washing machine are an inner tub and a pulsator installed at the bottom of the inner tub. When the washing machine is working, the motor drives the pulsator to rotate repeatedly in the forward and reverse directions to drive the water flow in the inner tub to rotate in the forward and reverse directions, so that the water flow produces impact force to rub against the clothes to achieve the washing purpose.

[0003] The pulsator of the washing machine is a circular pulsator disc provided with reinforcing ribs. Through the rotation of the pulsator disc, the reinforcing ribs drive the water flow to rotate, thereby realizing the cleaning of the clothes. However, such a pulsator disc is generally installed at the bottom of the inner tub and rotates at the bottom to drive the water flow. When the reinforcing ribs are small, the water flow intensity is not enough, but when the reinforcing ribs are large, the clothes will be abraded, which cannot meet the high efficiency of washing. When the pulsator disc rotates, if the reinforcing ribs are small, the speed of the water flow driven by the reinforcing ribs is not enough, which cannot clean the clothes with high intensity and cannot guarantee the cleanliness of the clothes. If the reinforcing ribs are too large, the water flow intensity will increase, but in the process of washing, the contact between the clothes and the reinforcing ribs will be more, which will cause abrasion of the clothes and affect the user experience.

[0030] In order to make the person skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without creative labor should belong to the protection scope of the present application.

[0031] In some technologies, the water flow intensity is small during the washing of the pulsator washing machine, and the stains on the clothes to be washed cannot be cleaned. In order to solve the technical problem, the present application provides a pulsator assembly and a washing machine. The structures of the parts of the pulsator assembly and the washing machine will be described below:

[0032] For example, the pulsator of the washing machine is a circular pulsator disc provided with reinforcing ribs. Through the rotation of the pulsator disc, the water flow is rotated by the reinforcing ribs, so as to realize the cleaning of the clothes. The pulsator disc is generally mounted at the bottom of the inner tub and rotates to drive the water flow. When the reinforcing rib is small, the water flow intensity is not enough, and when the reinforcing rib is large, it will cause the abrasion of the clothes, and cannot meet the high efficiency of washing. The speed of the water flow driven by the reinforcing rib of the ordinary pulsator disc is not enough when rotating, and the clothes cannot be cleaned with high intensity, and the cleanliness of the clothes cannot be guaranteed. When the reinforcing rib is too high, the water flow intensity will increase, but during the washing process, the contact between the clothes and the reinforcing rib will be more, which will cause the abrasion of the clothes for a long time, and affect the user experience.

[0033] Exemplarily, the pulsator of the washing machine also adopts a double-pulsator technology, that is, two pulsators are installed at the bottom and the middle of the washing barrel, the middle pulsator is connected through a column and a gear, and the water flow is strengthened through the double-pulsator system. This method forms a vortex at the bottom of the washing barrel, the inner pulsator is arranged at the middle and upper part of the washing barrel through the inner pulsator shaft, and the two side wave plates on the inner pulsator form a vortex at the upper part of the washing barrel, thereby enhancing the stirring capacity of the water flow in the washing barrel. The double-pulsator enhances the cleaning strength of the clothes. Meanwhile, under the driving action of the transmission gear, the rotation directions of the driving gear and the inner gear are opposite, so that the outer pulsator and the inner pulsator rotate in opposite directions. Relative to the single-pulsator structure, the clothes are subjected to bidirectional action, and the problem of entanglement of the clothes caused by the rotating vortex is solved to a certain extent. However, the installation of the double-pulsator structure of the washing machine is relatively complex, the pulsator assembly cannot be integrated with the washing machine, the installation is relatively troublesome, when one pulsator fails, the operation of the other pulsator will be affected, the service life of the two pulsators is relatively short, and the user has a poor use experience.

[0034] As shown in Figure 1 , it is a structure diagram of a pulsator assembly provided in the present application.

[0035] In view of the above problems, the first aspect of the present application provides a pulsator assembly, which comprises:

[0036] A pulsator disc 1 is provided with a plurality of lifting ribs 2. In the present application, the pulsator disc 1 is arranged at the bottom of the washing machine. Due to the arrangement of the stirring column 3, the height of the lifting ribs 2 arranged on the pulsator disc 1 can be slightly lower. It can be understood that when the washing machine is running, the clothes will float slightly due to the buoyancy of the water after the water is injected into the inner barrel of the washing machine, so as to separate from the pulsator disc 1 arranged at the bottom of the washing machine. Since the height of the lifting ribs 2 in the present application is relatively low, the washing clothes will almost not be in contact during the cleaning of the washing clothes, so as to avoid friction with the washing clothes and cause wear of the washing clothes.

[0037] A stirring column 3 is connected with the pulsator disc 1 and arranged at the center of the pulsator disc 1. A reinforcing rib 31 is arranged on the outer side of the stirring column 3 in a spiral shape. The water flow is strengthened through the common operation of the pulsator disc 1 and the stirring column 3, so as to realize further cleaning of the clothes.

[0038] Exemplarily, the stirring column 3 and the pulsator disc 1 are integrally arranged. Through the integral arrangement of the stirring column 3 and the pulsator disc 1, the manufacturing time of the pulsator assembly can be greatly reduced, and the strength of the pulsator assembly is improved through the integral arrangement of the stirring column 3 and the pulsator disc 1, thereby increasing the service life of the pulsator assembly.

[0039] For example, through the cooperation of the impeller disc 1 and the stirring column 3, the water flow intensity is greatly improved. The stirring column 3 rotates at the middle position of the inner barrel of the washing machine, and the reinforcing ribs 31 arranged on the outer periphery of the stirring column 3 will not cause abrasion to the clothes. It can be understood that the clothes in the washing machine will be close to the inner wall of the inner barrel of the washing machine due to the centrifugal force during the operation of the washing machine, and will not be stagnant at the middle position of the inner barrel of the washing machine, so as not to come into contact with the reinforcing ribs 31 and cause abrasion to the clothes.

[0040] It is worth noting that, compared with the current double-impeller structure connected by gears to achieve water flow enhancement, the present application proposes a washing machine water flow enhancement impeller assembly, which can achieve water flow enhancement with a single impeller, simple structure and easy installation. In addition, compared with the current single-impeller structure, the washing water flow generated by the impeller of the present application is stronger, and the water flow intensity can reach a higher value, improving the washing water flow intensity on the clothes, making the attached stains on the clothes fibers fall off, and the cleanliness of the clothes after washing is higher, and the abrasion of the clothes is not increased. With the impeller assembly of the present application, the height of the reinforcing ribs is lower, and the abrasion of the clothes is smaller under the same cleaning degree.

[0041] In this embodiment, the distance between the reinforcing ribs 31 adjacent to each side of the stirring column 3 is equal. The reinforcing ribs 31 are arranged in a spiral shape outside the stirring column 3. It can be understood that the reinforcing ribs 31 are wound at a predetermined angle outside the stirring column 3, so that the distance between the reinforcing ribs 31 adjacent to each side of the stirring column 3 is equal, and thus the water flow velocity of the inner barrel of the washing machine is more uniform and stronger when the stirring column 3 rotates, thereby improving the washing water flow intensity on the clothes, making the attached stains on the clothes fibers fall off, and the cleanliness of the clothes after washing is higher.

[0042] In this embodiment, the height of the reinforcing ribs 31 is greater than the height of the lifting ribs 2. It can be understood that by setting the height of the reinforcing ribs 31 to be greater than the height of the lifting ribs 2, there is no gap between the lifting ribs 2 and the reinforcing ribs 31, preventing the clothes to be washed from being wound into the gap between the lifting ribs 2 and the reinforcing ribs 31 during the washing process of the washing machine.

[0043] In this embodiment, the distance between the edge of the reinforcing ribs 31 and the stirring column 3 is equal; it can be understood that the reinforcing ribs 31 are arranged with consistent width, on the one hand, the water flow velocity of the inner barrel of the washing machine is more uniform and stronger when the stirring column 3 rotates, thereby improving the washing water flow intensity on the clothes, making the attached stains on the clothes fibers fall off, and the cleanliness of the clothes after washing is higher; on the other hand, it can reduce the installation difficulty and manufacturing difficulty of the reinforcing ribs 31.

[0044] The distance between the edge of the reinforcing rib 31 and the stirring column 3 is less than half the diameter of the stirring column 3. To prevent the laundry from being in contact with the reinforcing rib 31 during the washing process of the washing machine, thereby causing the laundry to be worn, the distance between the edge of the reinforcing rib 31 and the stirring column 3 is set to be less than half the diameter of the stirring column 3, thereby avoiding the problem of the laundry being in contact with the reinforcing rib 31 during the washing process of the washing machine, thereby causing the laundry to be worn.

[0045] In this embodiment, the lifting rib 2 comprises:

[0046] The first lifting rib 21 is arranged on the pulsator disc 1, and the second lifting rib 22 is arranged on the pulsator disc 1. The height of the second lifting rib 22 is less than the height of the first lifting rib 21.

[0047] For example, the number of lifting ribs 2 in this application can be set to 6, of which 3 are first lifting ribs 21, i.e. high lifting ribs, and 3 are second lifting ribs 22, i.e. low lifting ribs. By arranging the first lifting ribs 21 and the second lifting ribs 22 on the pulsator disc 1, when the pulsator disc 1 rotates, the lifting ribs 2 of different heights will make the water flow during washing stronger, so that the surface of the laundry is in full contact with the water flow, and the laundry can be washed more cleanly. The first lifting rib 21 and the second lifting rib 22 are arranged alternately on the pulsator disc 1.

[0048] For example, the beneficial effects of the lifting rib 2 are as follows:

[0049] I. Improve washing effect:

[0050] Enhance washing power: When the pulsator disc 1 rotates, the lifting rib 2 will rotate with it and drive the water flow and the laundry to move. The arrangement of one high and one low lifting rib 2 makes the water flow at different positions of the pulsator have different speeds and directions, thereby enhancing the washing power of the laundry and helping to remove stubborn stains on the laundry.

[0051] Optimize water flow distribution: By arranging one high and one low lifting rib 2, the distribution of water flow in the washing machine drum can be more effectively guided, so that the water flow is more uniform and powerful, improving the washing effect.

[0052] II. Reduce laundry wear:

[0053] Disperse pressure: During the washing process, the laundry will be subjected to pressure from the pulsator and the lifting rib 2. The arrangement of one high and one low lifting rib 2 can disperse this pressure, reduce the area and time of direct contact between the laundry and the pulsator, and thereby reduce the risk of laundry wear.

[0054] Protecting clothes: due to the height difference of the lifting ribs 2, clothes will be more evenly dispersed in the washing machine inner drum during washing, avoiding local wear caused by clothes accumulation.

[0055] III. Improve the stability of the washing machine:

[0056] Balancing water flow: the high and low lifting ribs 2 help balance the water flow in the washing machine inner drum, reducing washing machine shaking and noise caused by unbalanced water flow.

[0057] Enhance the stability of the impeller: the arrangement of the lifting ribs 2 also enhances the stability of the impeller, making it more stable at high speed, reducing washing machine failures caused by unstable impeller.

[0058] IV. Energy saving and water saving:

[0059] Optimize washing efficiency: by improving washing effect and reducing clothes wear, the high and low lifting ribs 2 help optimize washing efficiency, saving energy and water resources.

[0060] Reduce repeated washing: due to the improved washing effect, clothes can achieve good cleanliness in the first washing, reducing the number of repeated washing and water consumption.

[0061] In this embodiment, the side of the lifting rib 2 away from the impeller disc 1 is arc-shaped. To prevent the lifting rib 2 from scratching clothes during washing, causing clothes to wear, the side of the lifting rib 2 away from the impeller disc 1 is set as arc-shaped, thereby preventing clothes from wearing during washing on the one hand, and improving the flow rate of water flow during washing on the other hand.

[0062] The second aspect of the application provides a washing machine, comprising:

[0063] A impeller assembly as described in any of the above first aspect embodiments;

[0064] The impeller assembly is arranged at the bottom of the washing machine inner drum.

[0065] It is worth noting that the effect of the above washing machine embodiment in operation can refer to the effect of the above impeller assembly embodiment, which will not be repeated here.

[0066] As shown in Figure 2 , it is a structural diagram of the mounting slot 11 in the application.

[0067] In this embodiment, the mounting slot 11 is arranged at the center of the impeller disc 1; wherein the mounting slot 11 and the washing machine inner drum are penetrated by a screw, so that the impeller assembly is connected to the bottom of the washing machine inner drum.

[0068] Exemplarily, the wave plate 1 in the present application is provided with a mounting groove 11 at the center. When the wave plate assembly is mounted on the bottom of the inner tub of the washing machine, only the screw needs to be penetrated through the mounting groove 11 and the bottom of the inner tub of the washing machine, and the mounting work of the wave plate assembly can be completed. On the one hand, the mounting speed of the wave plate assembly can be improved, and on the other hand, the repair difficulty of the wave plate assembly can be reduced.

[0069] As shown in Figure 3 , it is a structure diagram of the inner tub in the present application.

[0070] In this embodiment, the inner tub of the washing machine is provided with a plurality of ribs 4. The shape of the rib 4 can be S-shaped, whale wing, wringer type, fish tail, etc. The ribs 4 with the above shapes may have slight differences in washing effect, but can improve the washing efficiency to a certain extent.

[0071] Exemplarily, the rib 4 has the following beneficial effects:

[0072] I. Lifting and beating action:

[0073] When the inner tub of the washing machine rotates, the rib 4 will drive the clothes to roll in the tub. When the clothes contact the rib 4, they will be constantly lifted upwards. When the clothes are lifted to a certain height, they will fall back to the bottom of the washing drum due to gravity, producing a beating effect. The above beating effect helps to more effectively remove stains on the clothes.

[0074] II. Rubbing action:

[0075] During the washing process, relative movement occurs between the clothes and the rib 4, as well as between the clothes and the clothes, thereby producing a rubbing effect. The above rubbing effect helps to penetrate the fibers of the clothes, remove stubborn stains, and improve the washing effect.

[0076] III. Enhancing the rigidity of the inner tub:

[0077] The arrangement of the rib 4 can also enhance the rigidity of the inner tub of the washing machine to a certain extent, making it more durable. This helps to prolong the service life of the washing machine and ensure its stability and safety during high-speed operation.

[0078] The application provides a pulsator assembly and a washing machine. When the washing machine is started, the motor drives the whole pulsator assembly to work. The lifting ribs 2 on the pulsator disc 1 rotate to drive the water flow. The rotation of the water flow washes the clothes. The washing mode can be selected according to different programs, which greatly increases the user experience, makes the washing machine more convenient and efficient, and the water flow is stronger and will not damage the clothes. The installation is convenient. Only one pulsator screw is needed to fix the pulsator in the inner barrel. The operation of the pulsator assembly can increase the water flow intensity by 30%. Because the lifting ribs 2 and the reinforcing ribs 31 work together, the water flow fully contacts the surface of the clothes, and the removal rate of stains reaches 95%. Because the lifting ribs 2 on the pulsator disc 1 are low, the abrasion of the clothes is greatly reduced, and the user experience is greatly improved.

[0079] The above detailed description further describes the purposes, technical solutions and beneficial effects of the embodiments of the application. It should be understood that the above is only a specific implementation of the embodiments of the application and is not used to limit the protection scope of the embodiments of the application. Any modification, equivalent replacement, improvement, etc. made on the basis of the technical solutions of the embodiments of the application should be included in the protection scope of the embodiments of the application.
