Description

TECHNICAL FIELD

[0001] The present application belongs to the field of washing technology, and particularly relates to a washing device. BACKGROUND

[0002] At present, full-automatic washing machines bring more and more convenience to people in daily life, and become one of the indispensable household appliances in people's daily life. There are two common types of washing machines today, namely, a pulsator washing machine and a drum washing machine. The pulsator washing machine is to make the water flow in the barrel form different vortexes under the rotation of the pulsator, so that the clothes are rolled over with the water flow and also produce mutual friction, thereby achieving the effect of washing clothes. The drum washing machine is to make the drum rotate by the mechanical work of the motor, and the clothes are repeatedly lifted to a high place and then fall, so as to achieve the washing of clothes.

[0003] However, the existing pulsator washing machine is designed with a pulsator structure at the bottom of the washing barrel, and the pulsator drives the clothes to rotate in the forward and reverse directions during the washing process. The washing method of rotating in the forward and reverse directions makes the clothes easily entangled with each other, not only needs to manually separate the clothes after the washing is completed, but also often causes serious wear of the clothes. The washing effect of the drum washing machine is relatively not ideal.

[0004] Therefore, there is a need in the art for a new washing device to solve the above problems existing in the prior art. SUMMARY

[0005] In view of the problems that the clothes are easily entangled in the pulsator washing machine and the washing effect of the drum washing machine is not ideal in the prior art, the present application provides a washing device, which comprises a washing barrel, and an external drive part of the washing barrel, characterized in that a driving extrusion part and a passive extrusion part are arranged in the washing barrel; the driving extrusion part is drivingly connected with the output end of the drive part, so that the driving extrusion part can rotate with the rotation of the output end of the drive part; and the passive extrusion part is slidingly sleeved with the output end of the drive part, so that the passive extrusion part does not rotate with the rotation of the output end of the drive part.

[0006] In the preferred technical scheme of the above washing device, the output end of the drive part is directly drivingly connected with the driving extrusion part.

[0007] In the preferred technical scheme of the above washing device, a driving shaft body is further arranged between the drive part and the driving extrusion part, one end of the driving shaft body is drivingly connected with the output end of the drive part, the other end of the driving shaft body enters the washing barrel and is drivingly connected with the driving extrusion part, and the passive extrusion part is slidingly sleeved with the driving shaft body.

[0008] In the preferred technical scheme of the washing device, the driving shaft body is a spline, the driving extrusion part is provided with a groove body matched with the spline, and the spline is arranged in the groove body.

[0009] In the preferred technical scheme of the washing device, the output end of the driving part is drivingly connected with the washing barrel, and the driving extrusion part is fixedly arranged in the inside of the washing barrel.

[0010] In the preferred technical scheme of the washing device, a connecting shaft body is fixedly arranged at the center line of the washing barrel, and the passive extrusion part is rotatably connected with the connecting shaft body.

[0011] In the preferred technical scheme of the washing device, the inside of the washing barrel is further provided with a slide channel, and the driving extrusion part and / or the passive extrusion part is arranged in the slide channel.

[0012] In the preferred technical scheme of the washing device, the driving extrusion part and the passive extrusion part are both provided with through holes.

[0013] In addition, the washing device provided by the application further comprises a washing barrel, the outside of the washing barrel is provided with a driving part, and the inside of the washing barrel is provided with a driving extrusion part and a passive extrusion part; the driving extrusion part is drivingly connected with the output end of the driving part, so that the driving extrusion part can rotate with the rotation of the output end of the driving part; the passive extrusion part is slidingly connected with the washing barrel, so that the passive extrusion part does not rotate with the rotation of the output end of the driving part and can rotate around the center line of the washing barrel.

[0014] In the preferred technical scheme of the washing device, the inside of the washing barrel is further provided with a slide channel, and the passive extrusion part is arranged in the slide channel and is not connected with the output end of the driving part.

[0015] It can be understood by those skilled in the art that, in the technical scheme of the application, the washing device comprises a washing barrel, and the outside of the washing barrel is provided with a driving part, and the inside of the washing barrel is provided with a driving extrusion part and a passive extrusion part; the driving extrusion part is drivingly connected with the output end of the driving part, so that the driving extrusion part can rotate with the rotation of the output end of the driving part; and the passive extrusion part is slidingly connected with the output end of the driving part, so that the passive extrusion part does not rotate with the rotation of the output end of the driving part.

[0016] With the above-described configuration, the washing device of the present invention, in the same size washing area, compared with the structure where the passive squeezing part is fixed, requires a smaller rotation angle for the active squeezing part to maintain the squeezing force, thus resulting in a faster washing speed. Furthermore, after being squeezed, the washing load can be more freely stretched due to the rotation of the passive squeezing part, which is beneficial for the next squeezing and washing, thereby improving the washing effect and washing ratio of the washing load. During the washing process, the washing load is less likely to tangle and suffers less wear. Attached Figure Description

[0026] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the invention and are not intended to limit the scope of protection of the invention. Those skilled in the art can make adjustments as needed to adapt to specific applications. For example, although the first embodiment in the specification is described as an example of the drive shaft being connected to the matching groove of the drive extrusion part via a spline, the present invention can obviously employ other similar means, such as an interference fit between the drive shaft and the groove of the drive extrusion part or a bolted connection, as long as the drive shaft can drive the drive extrusion part to rotate when it rotates.

[0027] It should be noted that in the description of this invention, terms such as "inner" and "outer" indicating directional or positional relationships are based on the directional or positional relationships shown in the accompanying drawings. This is merely for ease of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "connection" and "provided with" 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 direct connection or an indirect connection through an intermediate medium, etc. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, Figure 1 This is a front view of the first embodiment of the present invention. Figure 2 This is a schematic diagram of the structure of the first embodiment of the present invention. Figure 3 for Figure 2The diagram shows the structure of the washing tub after removing the side wall of the washing tub. This describes the first embodiment of the washing device of the present invention. To solve the problems of existing pulsator washing machines easily tangling clothes and drum washing machines having unsatisfactory washing effects, the present invention provides a washing device including a washing tub 1. A drive unit 2 is provided on the outside of the washing tub 1. The drive unit 2 can be a motor, or a motor combined with a reducer, or other common drive components. An active squeezing unit 3 and a passive squeezing unit 4 are provided inside the washing tub 1. Both the active squeezing unit 3 and the passive squeezing unit 4 have through holes 8. An active shaft 5 is also provided between the drive unit 2 and the active squeezing unit 3. One end of the active shaft 5 is driven and connected to the output end of the drive unit 2, and the other end of the active shaft 5 enters the washing tub 1 and is driven and connected to the active squeezing unit 3. The active shaft 5 is splined. The active squeezing unit 3 has a groove 9 that matches the spline, and the spline is located in the groove 9 so that the active squeezing unit 3 can rotate with the rotation of the output end of the drive unit 2. The passive squeezing unit 4 is slidably sleeved with the active shaft 5 so that the passive squeezing unit 4 does not rotate with the rotation of the output end of the drive unit 2. The washing tub 1 is also provided with a slide 7 at the bottom of the interior, and the active squeezing part 3 and the passive squeezing part 4 are both located in the slide 7.

[0030] The advantages of the above arrangement are as follows: In this embodiment, the active squeezing part 3 and the passive squeezing part 4 divide the washing tub 1 into two washing chambers. The washing load to be washed, such as clothes, is placed into the two washing chambers between the active squeezing part 3 and the passive squeezing part 4. The driving part 2 drives the active shaft 5 to rotate the active squeezing part 3 inside the washing tub 1, while the passive squeezing part 4 does not rotate with the rotation of the active shaft 5. Thus, for example, when the active squeezing part 3 rotates clockwise and squeezes the clothes together with the passive squeezing part 4, the passive squeezing part 4 also rotates clockwise away from the active squeezing part 3 under the action of force. Moreover, while rotating, the passive squeezing part 4 can also squeeze the clothes placed in the other washing chamber to a certain extent, and the squeezed clothes are freely unfolded. The active squeezing part 3 then rotates counterclockwise until it squeezes the clothes together with the passive squeezing part 4 again. In a washing area of ​​the same size, because the active squeezing part 3 applies a force to the passive squeezing part 4 when it rotates clockwise, the passive squeezing part 4 rotates clockwise by a certain angle. Compared to a structure where the passive squeezing part 4 is stationary, the angle of rotation required for the active squeezing part 3 to rotate counterclockwise until it squeezes the passive squeezing part 4 again is reduced. This decreases the angle of rotation required for the active squeezing part 3 to rotate counterclockwise, thus improving washing efficiency and reducing energy consumption. Good washing results can be achieved by continuously reciprocating the rotation of the active squeezing part 3.

[0031] During the rotation of the active squeezing part 3, when it squeezes the clothes in one washing chamber together with the passive squeezing part 4, an impact water flow is formed during the squeezing motion. After the water flow passes through the through hole 8, it can rinse the clothes in the other washing chamber.

[0032] In addition, a slide 7 is provided in this embodiment to facilitate the rotation of the active squeezing part 3 and the passive squeezing part 4 inside the washing tub 1.

[0033] The following reference Figure 4 , Figure 4 This is a schematic diagram of the structure of the washing tub for removing the side wall of the washing tub according to the second embodiment of the present invention. The second embodiment of the washing device of the present invention will be described. The difference between this embodiment and the first embodiment is that, in this embodiment, the passive squeezing part 4 is slidably connected to the washing tub 1, the passive squeezing part 4 is disposed in the slide rail 7 and is not connected to the output end of the drive part 2, so that the passive squeezing part 4 does not rotate with the rotation of the output end of the drive part 2, and can rotate around the center line of the washing tub 1.

[0034] The advantage of the above-mentioned arrangement is that, in this embodiment, another structure is provided, in which the passive squeezing part 4 can rotate along the slide 7 when subjected to the force applied by the active squeezing part 3, without needing to be connected to the active shaft 5, and can still achieve a good washing effect.

[0035] The following reference Figure 5 , Figure 5 This is a schematic diagram of the structure of the washing tub with the side wall removed according to the third embodiment of the present invention, which will be used to describe the third embodiment of the washing device of the present invention.

[0036] The difference between this embodiment and the first embodiment is that in this embodiment, the output end of the drive unit 2 is directly connected to the washing tub 1, while the active squeezing unit 3 is fixedly disposed inside the washing tub 1. A connecting shaft 6 is fixedly disposed at the center line of the washing tub 1, and the passive squeezing unit 4 is rotatably connected to the connecting shaft 6, and the passive squeezing unit 4 is disposed inside the slide rail 7.

[0037] The advantage of the above-mentioned arrangement is that, in this embodiment, another structure is provided: the washing tub 1 drives the active squeezing part 3 to rotate, and when subjected to the force applied by the active squeezing part 3, the passive squeezing part 4 rotates around the connecting shaft 6, which can also achieve a good washing effect.

[0038] The following reference Figure 6 , Figure 6 This is a schematic diagram of the structure of the washing tub with the side wall removed according to the fourth embodiment of the present invention, which will be used to describe the fourth embodiment of the washing device of the present invention.

[0039] The difference between this embodiment and the third embodiment is that, in this embodiment, there is no connecting shaft 6, and the passive pressing part 4 is directly and slidably disposed in the slide 7.

[0040] The advantage of the above configuration is that, in this embodiment, another structure is provided. The washing tub 1 drives the active squeezing part 3 to rotate. When subjected to the force applied by the active squeezing part 3, the passive squeezing part 4 rotates along the slide 7 around the center line of the washing tub 1, which can also achieve a good washing effect.

[0041] It should be noted that the above embodiments are merely used to illustrate the principles of the present invention and are not intended to limit the scope of protection of the present invention. Without departing from the principles of the present invention, those skilled in the art can adjust the above structure so that the present invention can be applied to more specific application scenarios.

[0042] For example, in an alternative embodiment, in the first embodiment, the output end of the drive unit 2 can also be directly driven connected to the active squeezing unit 3. This can be achieved by the output end of the drive unit 2 entering the washing tub 1 and being directly driven connected to the active squeezing unit 3 (not shown in the figure), or by the active squeezing unit 3 extending out of the washing tub 1 and being directly driven connected to the active squeezing unit 3 (not shown in the figure), and other various connection methods. These do not deviate from the principles of the present invention and therefore all fall within the protection scope of the present invention.

[0043] For example, in another alternative embodiment, in the first and second embodiments, the slide 7 may be provided on the inner side wall of the washing tub 1 (not shown in the figure); or both the inner side wall and the inner bottom of the washing tub 1 may be provided with slides 7 (not shown in the figure). In this case, the active squeezing part 3 and the passive squeezing part 4 may be simultaneously connected to the slides 7 (not shown in the figure) on the inner side wall and the inner bottom of the washing tub 1, or one of the active squeezing part 3 and the passive squeezing part 4 may be connected to the slide 7 on the inner side wall of the washing tub 1, while the other is connected to the slide 7 (not shown in the figure) on the inner bottom of the washing tub 1. These do not deviate from the principle of the present invention, and therefore all fall within the protection scope of the present invention.

[0044] For example, in another alternative implementation, in the third and fourth embodiments, the slide 7 may be provided on the inner side wall of the washing tub 1 (not shown in the figure); or the inner side wall and the inner bottom of the washing tub 1 may both be provided with slide 7 (not shown in the figure), in which case the passive squeezing part 4 may simultaneously connect to the slide 7 on the inner side wall and the inner bottom of the washing tub 1.

[0045] For example, in another alternative embodiment, in the second and fourth embodiments, to prevent the passive squeezing part 4 from detaching from the slide 7 during rotation due to excessive rotation speed or light weight, thus affecting normal washing or even creating a safety hazard, the slide 7 can be configured with a T-shaped cross-section (not shown in the figure), and the corresponding part connecting the passive squeezing part 4 to the slide 7 can also be configured with a T-shaped cross-section (not shown in the figure). Anything that prevents the passive squeezing part 4 from detaching from the slide 7 is acceptable. These do not depart from the principles of the present invention and therefore all fall within the protection scope of the present invention.

[0046] For example, in another alternative embodiment, the slide rail 7 may not be provided. For instance, in the first embodiment, the bottom height of the active squeezing part 3 and the passive squeezing part 4 is slightly higher than the bottom height of the washing tub 1, so that the active squeezing part 3 and the passive squeezing part 4 are suspended above the bottom of the washing tub 1 (not shown in the figure); in the third embodiment, the passive squeezing part 4 is not directly connected to the interior of the washing tub 1, and the bottom height of the passive squeezing part 4 is slightly higher than the bottom height of the washing tub 1, so that the passive squeezing part 4 is suspended above the bottom of the washing tub 1 (not shown in the figure); in the fourth embodiment, the suspension of the passive squeezing part 4 is achieved directly by magnetic levitation (not shown in the figure). The effect of rotational squeezing and washing can be achieved without providing the slide rail 7. These all do not deviate from the principle of the present invention and therefore fall within the protection scope of the present invention.

[0047] For example, in another alternative embodiment, a filter screen (not shown in the figure) can be provided in the through hole 8 in the above embodiments to avoid the through hole 8 being blocked by various impurities during the washing process, thus affecting the washing efficiency. These modifications do not deviate from the principles of the present invention and therefore all fall within the protection scope of the present invention.

[0048] For example, in another alternative embodiment, in the above embodiments, the active squeezing part 3 and the passive squeezing part 4 can also be configured as a combination of two parts made of materials with different hardness, that is, both the active squeezing part 3 and the passive squeezing part 4 have a hard squeezing part on one side and a soft squeezing part on the other side (not shown in the figure). Through different combinations, four types of washing chambers can be realized, namely, hard active squeezing part and hard passive squeezing part, hard active squeezing part and soft passive squeezing part, soft active squeezing part and hard passive squeezing part, and soft active squeezing part and soft passive squeezing part, so that clothes of different materials can be placed into the corresponding washing chambers for washing. These do not deviate from the principle of the present invention, and therefore all fall within the protection scope of the present invention.

[0049] For example, in another alternative embodiment, in the above embodiments, the active squeezing part 3 and the passive squeezing part 4 can also be configured to be detachably connected. When the active squeezing part 3 and the passive squeezing part 4 malfunction, need cleaning, or need to be replaced with other models (such as different hardness or different number, size, or density of through holes 8), the active squeezing part 3 and the passive squeezing part 4 can be easily removed from the washing tub 1 and installed. These do not depart from the principle of the present invention, and therefore all fall within the protection scope of the present invention.

[0050] For example, in another alternative embodiment, in the above embodiments, there may also be two active squeezing units 3 and two passive squeezing units 4. During rotation, the two active squeezing units 3 maintain the division of the washing tub 1 into two washing chambers of equal area. The two active squeezing units 3 and the two passive squeezing units 4 are staggered, and the two passive squeezing units 4 are respectively disposed between the two active squeezing units 3 (not shown in the figure). This embodiment can also achieve the effect of rotational squeezing washing.

[0051] Specifically, in the first embodiment, both active squeezing parts 3 are fixedly connected to the active shaft 5, and both passive squeezing parts 4 are slidably sleeved with the active shaft 5 (not shown in the figure). In the second embodiment, both active squeezing parts 3 are fixedly connected to the active shaft 5, and both passive squeezing parts 4 are slidably connected to the slide rail 7 (not shown in the figure). In the third embodiment, both active squeezing parts 3 are fixedly connected to the washing tub 1, and both passive squeezing parts 4 are rotatably connected to the connecting shaft 6 (not shown in the figure). In the fourth embodiment, both active squeezing parts 3 are fixedly connected to the washing tub 1, and both passive squeezing parts 4 are slidably connected to the slide rail 7 (not shown in the figure).

[0052] In this embodiment, the washing tub 1 is divided into four washing chambers. Different materials of active squeezing parts 3 and passive squeezing parts 4 can be used to wash clothes of different materials. For example, each of the two active squeezing parts 3 and the two passive squeezing parts 4 can be made of one hard squeezing part and one soft squeezing part. Thus, the squeezing parts participating in the squeezing in the four washing chambers are respectively a hard active squeezing part and a hard passive squeezing part, a hard active squeezing part and a soft passive squeezing part, a soft active squeezing part and a hard passive squeezing part, and a soft active squeezing part and a soft passive squeezing part. Furthermore, during the squeezing process, the active squeezing part 3 changes from a certain speed to zero, while the passive squeezing part 4 changes from zero speed to a certain speed and then back to zero. Therefore, the squeezing effect on the clothes is different when the active squeezing parts 3 and passive squeezing parts 4 are made of materials with different hardnesses. Clothes of different materials can be placed in for washing. These practices do not deviate from the principles of this invention and therefore fall within the protection scope of this invention.

[0053] For example, in another alternative embodiment, in the above embodiments, there may be three active squeezing units 3 and three passive squeezing units 4 (not shown in the figures), which can achieve the same rotational squeezing washing effect and divide the washing tub 1 into six washing chambers. These do not deviate from the principle of the present invention and therefore all fall within the protection scope of the present invention.

[0054] In summary, within the same washing area, compared to a structure where the passive squeezing part is fixed, the active squeezing part in this invention requires a smaller rotation angle to maintain the squeezing force, resulting in a faster washing speed. Furthermore, the rotation of the passive squeezing part after squeezing enhances the free-flowing effect of the washing load, facilitating subsequent squeezing and washing, thus improving the washing effect and cleaning ratio. During the washing process, the washing load is less prone to tangling and experiences less wear. This invention also allows for flexible selection of squeezing parts with different hardness depending on the material of the clothing, preventing a shortened lifespan of the washing load during washing.

[0055] Those skilled in the art will understand that the above-described washing apparatus also includes other known structures, such as processors, controllers, and memories. These memories include, but are not limited to, random access memory (RAM), flash memory, read-only memory (ROM), programmable read-only memory (PROM), volatile memory, non-volatile memory, serial memory, parallel memory, or registers. Processors include, but are not limited to, CPLD / FPGA, DSP, ARM processors, and MIPS processors. To avoid unnecessarily obscuring the embodiments of the present invention, these known structures are not shown in the accompanying drawings.

[0056] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
