Detailed Implementation Modes

[0029] Here, exemplary embodiments will be described in detail, and examples thereof are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numerals in different drawings represent the same or similar elements. The implementation modes described in the following exemplary embodiments do not represent all implementation modes consistent with the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0030] A first aspect of the embodiments of the present disclosure provides a drum assembly. Referring to Figure 1 and Figure 2 , it may include a first drum 30, a door seal 32, and a drum cover 33. Among them, the door seal 32 can be connected to the drum opening 300 of the first drum 30, and the drum cover 33 can be used to cover the door seal 32. Referring to Figures 1 to 4 , the first drum 30 includes an outer cylinder 302 and an inner cylinder 303 rotatably arranged inside the outer cylinder 302. The drum opening 300 refers to the drum opening of the inner cylinder 303 for loading clothes. A stopping part 36 may be provided at the drum opening 300, and the stopping part 36 can be used to stop at the rear end of the door seal 32 to prevent the clothes inside the first drum 30 from impacting forward the connection gap between the drum cover 33 and the door seal 32, causing abnormal noise. It should be noted that the front and rear in this article are defined according to the direction of the device during use. The side facing the user is the front, and the opposite is the rear. Specifically, reference can be made to the directions indicated by the arrows in Figure 2 and Figure 4 .

[0031] Exemplarily, referring to Figure 2, the first drum 30 can be configured to gradually expand from the bottom 304 of the drum to the mouth 300 of the drum, and the stop portion 36 can be configured to be annular, and the inner diameter of the stop portion 36 can be greater than the diameter of the bottom 304 of the drum. Among them, the first drum 30 is designed to gradually expand from the bottom 304 of the drum to the mouth 300 of the drum, which is convenient for taking clothes at the mouth 300 of the drum. And because the first drum 30 is formed into a gradually expanding shape, the clothes are easy to slide toward the mouth 300 of the drum to hit the lid 33 of the drum. The stop portion 36 can form a partition between the first drum 30 and the lid 33 of the drum, effectively preventing the clothes from sliding or hitting toward the mouth 300 of the drum. At the same time, the inner diameter of the stop portion 36 is designed to be greater than the diameter of the bottom 304 of the drum, so that the stop portion 36 does not hinder the normal putting-in or taking-out actions of the clothes, making it more convenient to access the clothes.

[0032] In some embodiments, the radius of the body of the first drum 30 can be 56 mm to 96 mm, for example, it can be 60 mm, 70 mm, 76.2 mm or 90 mm, etc. The radius of the mouth 300 of the first drum 30 can be 62 mm to 102 mm, for example, it can be 72 mm, 82.3 mm or 92 mm, etc. Since the diameter size of the body of the drum is small, it causes certain inconvenience in taking out clothes from the first drum 30. Therefore, the first drum 30 can be formed into a structure that gradually expands toward the mouth 300 of the drum to offset the influence of the small size of the mouth 300 of the drum on the inconvenient taking of clothes.

[0033] In some embodiments, the inner diameter of the stop portion 36 can be 112 mm to 126 mm, for example, it can be 115 mm, 118.8 mm or 120 mm, etc. When the inner diameter of the stop portion 36 is selected within this range, it is more suitable for accessing clothes into the first drum 30 and is not likely to hinder the access actions of the clothes.

[0034] Exemplarily, referring to Figure 2 and Figure 3 , the inner diameter of the door seal 32 can be not less than the inner diameter of the mouth 300 of the drum, so that when the door seal 32 is installed in front of the mouth 300 of the first drum 30, the door seal 32 does not block the access path of the clothes, facilitating the access of clothes into the first drum 30. At the same time, the inner diameter of the door seal 32 being not less than the inner diameter of the mouth 300 of the drum will also cause that after the lid 33 of the drum is snap-connected to the door seal 32, the clothes are more likely to cross the mouth 300 of the drum and enter the door seal 32 without obstruction, constantly causing abnormal noises. And the stop portion 36 provided at the mouth 300 of the drum can effectively prevent the clothes from entering and hitting the door seal 32.

[0035] Exemplarily, referring to Figure 3 and Figure 4, the drum cover 33 may include a door panel 331 and a protrusion 332. Among them, the door panel 331 can be covered on the outer edge of the door seal 32, the protrusion 332 can protrude backward from the door panel 331 into the door seal 32, and the stop portion 36 can block the gap between the protrusion 332 and the door seal 32 at the rear side of the door panel 331. In this embodiment, after the drum cover 33 is buckled, the door panel 331 can be covered on the outer edge of the door seal 32, and a connection structure with better sealing performance can be formed between the protrusion 332 protruding toward the door seal 32 and the door seal 32 to prevent water from leaking out of the inside of the first drum 30. At this time, the stop portion 36 can block the gap formed between the protrusion 332 and the door seal 32 at the rear side of the door panel 331 to effectively prevent clothes from entering the gap and impacting and flapping the protrusion 332 and the door seal 32 to cause abnormal noises, improving the user experience.

[0036] In some embodiments, referring to Figure 3 and Figure 4 , in the front-rear direction of the drum assembly, the rear end side of the stop portion 36 can be located before the rear end face of the protrusion 332 or flush with the rear end face of the protrusion 332, that is, the rear end side of the stop portion 36 does not extend backward beyond the protrusion 332. In this embodiment, the rear end side of the stop portion 36 can be arranged in a direction away from the inside of the first drum 30 relative to the rear end face of the protrusion 332, or at least make the rear end side of the stop portion 36 flush with the rear end face of the protrusion 332, so that the stop portion 36 is not located inside the first drum 30, which can reduce the occupation of the internal clothes cleaning space of the first drum 30 by the stop portion 36, improve the clothes accommodation capacity of the internal space of the first drum 30, and at the same time prevent the stop portion 36 located inside the first drum 30 from possibly partially hindering the rolling movement of the clothes, thereby scratching or damaging the clothes during the cleaning process.

[0037] In other embodiments, the rear end face of the protrusion 332 can be arranged in a direction away from the inside of the first drum 30 of the drum opening 300 to ensure that the protrusion 332 only protrudes toward the door seal 32 and does not extend into the first drum 30, thereby avoiding the occupation of the internal space of the first drum 30 by the protrusion 332.

[0038] Exemplarily, the stopper portion 36 can be made of rubber. Since rubber-like materials have good softness, they will not scratch or damage the clothes inside the first drum 30, protecting the cleanliness and safety of the clothes. At the same time, rubber-like materials also have a certain deformation ability. When accessing clothes, the stopper portion 36 can be appropriately pressed and deformed, temporarily expanding the size of the access opening at the drum opening 300, facilitating the putting in or taking out of clothes, and returning to its original state after accessing clothes, having a good stopping effect. Here, the stopper portion 36 can be an integral structure with the door seal 32 to simplify the production process and improve the positioning strength of the stopper portion 36. Or, in the case of using rubber-like materials, it can be sleeved and installed at the drum opening 300 of the first drum 30. When the two are in a split structure, the stopper portion 36 can be cleaned or replaced regularly to improve the cleanliness inside the first drum 30. The above two installation forms of the stopper portion 36 can be reasonably selected according to the actual use situation and the target audience of the user to have better applicability.

[0039] Exemplarily, the stopper portion 36 can be an integral structure with the first drum 30 to keep the relative position of the stopper portion 36 and the first drum 30 fixed, improve the positioning strength of the stopper portion 36, and make it not easy to separate or fall off relative to the first drum 30, ensuring the limiting effect of the stopper portion 36 on the clothes. Among them, the stopper portion 36 can be formed as a flanging structure that is the front edge of the drum opening 300 and turns inward into the first drum 30. This flanging structure can not only meet the stopping effect of the stopper portion 36, but also when observing from the outside to the inside of the drum, since it is integrally arranged with the first drum 30, the edge of the stopper portion 36 can be visually hidden and is not easy to be observed, thereby improving the aesthetics and neatness of the first drum 30.

[0040] Exemplarily, referring to Figure 1 and Figure 3 , a flange 31 can be installed at the front end of the drum 30, the door seal 32 can be installed on the flange 31, and the stopper portion 36 can be an integral structure with the flange 31. Among them, the flange 31 is fixedly connected to the drum opening 300, and the door seal 32 can be installed on the flange 31 in forms such as bolting, bonding or sleeving. The embodiments of the present disclosure do not specifically limit the connection methods of the above two. At the same time, the stopper portion 36 can be formed as an integral structure with the flange 31 to strengthen the positioning strength of the stopper portion 36, making it not easy to fall off relative to the first drum 30. At the same time, the integral structure is convenient for production and installation and can simplify the process flow.

[0041] Exemplarily, the stopper 36 can be an integral structure with the door seal 32. Since the door seal 32 is used to ensure the sealing performance of the interior of the first drum 30 after the drum cover 33 is fastened, the door seal 32 can be selected as a flexible material such as rubber. Due to the similar physical properties to the door seal 32, the stopper 36 can also be made of the same flexible material as the door seal 32, and the two are set as an integral structure to avoid damaging clothes. Moreover, the stopper 36 can be limited in its installation position by the door seal 32, and it is not easy to fall off relative to the first drum 30, having good positioning strength and improving the structural stability of the first drum 30.

[0042] In some embodiments, referring to Figure 3 , the door seal 32 can include a slot portion 321 and an elastic sealing portion 322. Among them, the slot portion 321 can be connected to the first drum 30, the elastic sealing portion 322 can be formed at the rear end of the slot portion 321, and the stopper 36 can be formed between the slot portion 321 and the elastic sealing portion 322. In this embodiment, the stopper 36 is arranged between the slot portion 321 and the elastic sealing portion 322. The slot portion 321 and the elastic sealing portion 322 can be used to limit the installation position of the stopper 36 to ensure that the stopper 36 can be fixed at the barrel opening 300 of the first drum 30 and is not easy to deform and fall off. At the same time, setting the stopper 36 here neither affects the positioning and assembly between the first drum 30, the door seal 32 and other structures, nor can it form a partition between the first drum 30 and the elastic sealing portion 322 to prevent clothes from entering the elastic sealing portion 322 and hitting and patting the elastic sealing portion 322 during the cleaning of clothes, reducing the service life of the elastic sealing portion 322, and thus improving the sealing performance of the door seal 32.

[0043] Exemplarily, referring to Figure 5 , the drum assembly can include a second drum 20. Among them, the diameter of the second drum 20 can be larger than the diameter of the first drum 30, and the first drum 30 can be arranged obliquely above the second drum 20 to reduce the overall height of the drum assembly and reduce space occupation. In this embodiment, the diameter of the first drum 30 can be set to 175 mm to 185 mm, and the diameter of the second drum 20 can be set to 533 mm to 543 mm. The diameter size of the second drum 20 is much larger than that of the first drum 30. Therefore, the first drum 30 can be arranged using the space obliquely above the second drum 20 to reduce the vertical or lateral dimensions of the device, and make the drum assembly layout compact, improving space utilization rate and overall structural stability.

[0044] In the second aspect of the embodiments of the present disclosure, a laundry treatment device is provided, including a housing 10 and a drum assembly arranged in the housing 10. The drum assembly is the drum assembly provided in the first aspect of the present disclosure, so it has all the technical effects of the above-mentioned drum assembly and will not be elaborated here.
