[0002] The washing machine has a history of more than a hundred years since its invention. With the development of technology, washing machines have gradually developed from their original simple cleaning functions to efficient and fast washing of clothes.

[0003] At present, for most drum washing machines on the market, a longer washing process is often required to achieve a good washing effect. Generally, lifting ribs are provided on the inner wall of the drum to enable the clothes to be pulled up with the movement of the drum and then thrown to the bottom of the drum, forming simulated clothing stirring, scrubbing and other actions. However, the effect is limited, especially for a large amount of clothes, it is often impossible to separate the entangled clothes, which leads to an increase in washing time. In order to increase the washing capacity, some manufacturers have set up a dual-power-driven inner drum, in which one part of the drum rotates forward and the other part rotates reversely to enhance the stirring and rubbing effect of the clothes. However, this method requires the configuration of two power systems, the drum motion control is complex, and the inner drum structure design is complex, and many changes are made to the original structure.

[0004] Therefore, a lightweight method is urgently needed to solve the above problems. Summary of the Invention

[0028] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0029] The foregoing and other purposes, features, aspects and advantages of the present invention will become more apparent so that those skilled in the art can implement them with reference to the text of the specification.

[0030] Example 1

[0031] Reference Figure 1 、 Figure 2As shown, an inner drum of a clothing care device comprises: a rotatable drum body 100 driven by a rotary power device; a track 120 extending in the direction of rotation is provided on the inner surface of the drum wall 110 of the drum body 100; at least one stirring rib 131 extending toward the drum body 100 is disposed in the track 120; wherein the stirring rib 131 can move relative to the drum wall 110 along the track 120; when the rotation state of the drum body 100 changes, the stirring rib 131 moves relative to the drum wall 110 under the action of inertia, thereby stirring the clothes inside the drum body 100. In this embodiment, as shown in FIG. Figure 4 As shown, the drum wall 110 includes a rear wall 111 and a front wall 112; wherein the track 120 is assembled with the rear wall 111 and / or the front wall 112, thereby achieving the installation of the track 120 and the drum wall 110. In other embodiments, the track 120 can be configured on the drum bottom 140, and the stirring ribs 131 extend from the bottom surface of the drum bottom 140 into the drum to stir the clothes in the drum.

[0032] It should be understood that changes in the rotational state include switching between forward and reverse rotation of the drum, changes in the drum speed, and cessation of drum rotation. For example, in this embodiment, when the drum switches between forward and reverse rotation, the stirring ribs 131 remain in their original motion state due to inertia, while the drum's motion state changes instantaneously under the braking of the rotary power device, thereby forming relative motion between the stirring ribs 131 and the drum, so that the stirring ribs 131 can form a pulling and blocking effect on the clothes moving with the drum, thereby enhancing the kneading effect on the clothes. In this embodiment, a non-powered method is used to achieve additional stirring of the clothes. Only a single rotary power device needs to be controlled to achieve additional processing effects on the clothes, saving equipment installation and debugging processes while saving energy consumption.

[0033] In particular, in order to cooperate with the inertia of the stirring ribs 131, by configuring the forward and reverse switching when the drum is in a lower circulation speed (non-spinning speed), such as switching back and forth five times in a 200-400r / min speed state, the effect of shaking the clothes is achieved; by configuring the forward and reverse switching when the drum is in a lower circulation speed, such as switching back and forth ten times in a 50-200r / min speed state, the effect of rubbing the clothes is achieved.

[0034] In some preferred embodiments, in order to enhance the inertia effect of the stirring ribs 131, a rolling assembly 132 is further included; Figure 3 As shown, the rolling component 132 is connected to the stirring rib 131 to form rolling contact between the stirring rib 131 and the track 120; in this embodiment, the rolling component 132 is realized by a roller, and rolling contact can also be achieved through structures such as rollers, balls or bearings, thereby reducing the resistance to movement and enhancing the inertia effect.

[0035] In some preferred embodiments, Figure 1 、 Figure 2 As shown, lifting ribs 150 are also fixed to the inner wall of the drum wall 110. When the rotation state of the drum body 100 changes, the agitating ribs 131, under the action of inertia, move relative to the lifting ribs 150 to rub the clothes. In this embodiment, the lifting ribs 150 are fixed to the drum wall 110 and rotate with the drum body 100. When the rotation state changes, the lifting ribs 150 and the agitating ribs 131 form a speed difference, resulting in relative movement. Under the combined action of the lifting ribs 150 and the agitating ribs 131, the clothes are rubbed and shaken in opposite directions. Furthermore, the projections of the lifting ribs 150 and the agitating ribs 131 along the axis of the drum body rotation do not overlap. During the relative movement of the lifting ribs 150 and the agitating ribs 131, the clothes are prevented from being pulled or pinched, effectively preventing excessive damage to the clothes.

[0036] In some preferred embodiments, Figures 1-4 As shown, the track 120 is arranged in a full circle. In this embodiment, the track 120 surrounds the inner surface of the cylinder wall 110, so that the three stirring ribs 131 can rotate cyclically in the track 120 to expand the rotation range brought by inertia. For example, under the action of inertia, the stirring rib 131 can rotate three times along the track 120.

[0037] In particular, such as Figure 3 、 Figure 4 As shown, it also includes a connecting ring 133; wherein, the connecting ring 133 is used to fixedly connect two adjacent stirring ribs 131; the connecting ring 133 connects the multiple stirring ribs 131 of the track 120 into a whole, forming the overall inertia effect of the multiple stirring ribs 131, while maintaining the distance between the stirring ribs 131, effectively avoiding the stirring ribs 131 from moving together due to gravity to affect the rotation balance of the cylinder, thereby forming a stirring effect at various locations on the circumference of the cylinder through the evenly spaced stirring ribs 131.

[0038] Furthermore, if Figure 4 As shown, the connecting ring 133 is installed in the track 120, and the track 120 wraps the connecting ring 133 to prevent the connecting ring 133 from directly contacting the clothes and preventing the clothes from being entangled in the connecting ring 133. More preferably, the connecting ring 133 and the track 120 form a relatively sealed structure, so that the track 120 forms a relatively closed environment, isolating the wash water in the drum from entering the track, preventing the track from corrosion and internal scaling, which affects the washing effect.

[0039] In other preferred embodiments, the track 120 is arranged in an arc shape (not shown); at least two tracks 120 are distributed on the inner surface of the cylinder wall 110, and the two tracks 120 are not connected to each other. In this embodiment, the stirring ribs 131 in a track 120 are limited to movement within the track, that is, the arc-shaped track 120 limits the range or amplitude of movement of the stirring ribs 131. For example, three 80° arc-shaped tracks are evenly distributed on the inner surface of the cylinder wall, that is, the stirring ribs in the first track can move within a range of 0°-80°, the stirring ribs in the second track can move within a range of 120°-200°, and the stirring ribs in the third track can move within a range of 240°-320°. It should be understood that the number of tracks can vary depending on the size of the cylinder diameter, and multiple stirring ribs can be configured in the track, with adjacent stirring ribs fixedly connected by a connecting structure; generally, the larger the cylinder diameter, the more tracks can be configured; the longer the track, the more stirring ribs can be accommodated.

[0040] Example 2

[0041] The present invention provides a clothing care device, comprising an inner drum 100 as described in Example 1. In some embodiments, the inner drum 100 can be configured as a flat drum; in other embodiments, the inner drum 100 can be configured as an inclined drum. The present invention utilizes a non-powered method to achieve additional agitation of the clothing, requiring only the control of a single rotary power device to achieve the additional treatment effect on the clothing. This reduces the installation and commissioning process of the clothing care device and saves energy.

[0042] In some embodiments, the clothing care device can be implemented as a dryer, which can quickly shake out the clothes and accelerate the drying process by switching between forward and reverse rotations at low speeds during the drying process; in other embodiments, the clothing care device can be implemented as a washing machine, which can enhance the washing effect of the clothes during the washing process by changing the rotation state of the drum; in still other embodiments, the clothing care device can be implemented as a washer-dryer, which can enhance the washing effect and accelerate the drying process during the washing and drying processes.

[0043] The above description is only an example of the present invention and is not intended to limit one or more embodiments of the present invention. For those skilled in the art, various changes and variations may be made to one or more embodiments of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of one or more embodiments of the present invention shall be included in the scope of the claims of one or more embodiments of the present invention.
