[0016] Other features and advantages of this disclosure will be described in detail in the following embodiments. [Brief explanation of the drawing]

[0017] The drawings are used to enhance the understanding of this disclosure, constitute part of this specification, and are used to illustrate this disclosure together with the following detailed description, but do not limit this disclosure.

[0018] [Figure 1] This is a schematic front view of a washing machine according to an embodiment of the present disclosure. [Figure 2] This is a schematic perspective view of a washing machine door assembly according to an embodiment of the present disclosure. [Figure 3] This is a schematic top view of a washing machine door assembly according to an embodiment of the present disclosure. [Figure 4] This is a schematic front view of a washing machine door assembly according to an embodiment of the present disclosure. [Modes for carrying out the invention]

[0019] Specific embodiments of this disclosure will be described in detail below with reference to the drawings. It should be understood that the specific embodiments described herein are used solely for the purpose of illustrating and interpreting this disclosure and are not intended to limit it.

[0020] In the present disclosure, unless otherwise specified, terms indicating directions such as "upper", "lower", "left", and "right" generally refer to the paper orientation of FIG. 1, and the front-back direction, up-down direction, and left-right direction are perpendicular to each other. Generally, the side facing the user of the washing machine is the front, and the side opposite to the user is the back. Also, the up-down direction refers to the gravitational direction of the washing machine. Also, terms such as "first" and "second" are used to distinguish one element from another, and there is no order or importance. Also, when referring to the drawings in the following description, the same reference numerals in different drawings represent the same or similar elements, but this will not be described in detail in the present disclosure.

[0021] In the related art, for a dual-drum washing machine with a standard housing, this dual-drum washing machine includes a first drum and a second drum, and the second drum is provided above the first drum. Since it is a standard housing, that is, the dimensions of the housing are constant, the height of the second drum is usually not less than the height of the conventional washing liquid input box. On the other hand, in the conventional manual input, since the water flow utilizes the gravity of water to flow the washing liquid in the washing liquid input box into the drum, the conventional manual input method cannot achieve the manual input of the washing liquid into the second drum.

[0022] To solve the above technical problems, the present disclosure provides a washing machine. Referring to FIGS. 1 to 4, this washing machine includes a first drum 1, a second drum 2, and a door assembly 3. The diameter of the second drum 2 is smaller than the diameter of the first drum 1, and the door assembly 3 is used to selectively cover the opening of the second drum. The door assembly 3 includes a door body 31, a protrusion 32, and an input device 33. The protrusion 32 is provided inside the door body 31, the input device 33 is provided on the protrusion 32, and has a washing liquid input port 50, a water supply port 10, and an outlet 20 communicating with both the washing liquid input port 50 and the water supply port 10.

[0023] According to the above technical solution, in the washing machine according to the present disclosure, a user can input a washing liquid into the input device 33 through the washing liquid input port 50. When the door assembly 3 closes the opening 2 of the second drum, the second drum 2 can perform washing of clothes. Since the input device 33 is provided on the protruding portion 32, the outlet 20 in this case communicates with the inside of the second drum 2. When water flows from the water supply port 10 into the input device 33, the water flow can be mixed with the washing liquid and flow into the inside of the second drum 2 from the outlet 20. Thereby, manual input of the washing liquid into the second drum 2 through the door can be realized.

[0024] In some embodiments of the present disclosure, referring to FIGS. 2 and 3, the input device 33 includes a mixing chamber 331. The mixing chamber 331 communicates with the water supply port 10 and the outlet 20, and the mixing chamber 331 further communicates with the washing liquid input port 50 and the outlet 20. By doing so, mixing of the water flow and the washing liquid can be realized better, and flowing the washing liquid to the outlet 20 by the water flow can be realized better.

[0025] In some embodiments of the present disclosure, referring to FIGS. 2 to 4, the input device 33 can include a siphon structure provided in the mixing chamber 331. The siphon structure can include a siphon tube 332 and a siphon cap 333. The siphon tube 332 communicates with the outlet 20. The siphon cap 333 is mounted on the siphon tube 332 and forms a siphon passage 30 together with the siphon tube 332.

[0026] According to the above technical proposal, as water continues to flow into the mixing chamber 331, the liquid level of the mixture in the mixing chamber 331 continues to rise. When the liquid level of the mixture rises above the siphon position of the siphon structure, a siphon effect occurs in the mixture, and it continues to reach the outlet 20 through the siphon passage 30, and then flows into the second drum 2. This makes it possible to manually dispense laundry liquid into the second drum 2 using a siphon method. Here, since the diameter of the second drum 2 is smaller than the diameter of the first drum 1, the second drum 2 can be used to wash clothes of a small volume or light weight, and the first drum 1 can be used to wash clothes of a large volume or heavy weight.

[0027] The principle by which the siphon effect occurs in the mixed liquid using the siphon tube 332 and the siphon cap 333 is well known to those skilled in the art, and therefore a detailed explanation is omitted here. Furthermore, the laundry liquid according to this disclosure may include, but is not limited to, detergent, fabric softener, disinfectant, etc. Moreover, the above mixed liquid can be understood as a mixture of water and laundry liquid. In some embodiments, the projection 32 may be formed of glass, but is not limited to this disclosure.

[0028] In some embodiments of this disclosure, referring to Figure 2, the dispensing device 33 may include a laundry liquid dispensing chamber 334, which communicates with a laundry liquid dispensing port 50 and a mixing chamber 331. In this way, the laundry liquid can flow from the laundry liquid dispensing port into the laundry liquid dispensing chamber and then into the mixing chamber, facilitating the mixing of the water flow and the laundry liquid.

[0029] In some embodiments of this disclosure, referring to Figure 2, a housing chamber 321 is provided in the protrusion 32, and both the mixing chamber 331 and the washing liquid dispensing chamber 334 are provided in the housing chamber 321. In this way, the mixing chamber 331 and the washing liquid dispensing chamber 334 can be arranged using the space of the protrusion 32 itself, which reduces the volume of the door assembly 3 and is advantageous in achieving rational use of the space in which the washing machine is installed.

[0030] In some embodiments of this disclosure, referring to Figures 2 and 3, the dispensing device 33 includes a cover 335, the cover 335 includes a first sub-cover 3351, the first sub-cover 3351 is located above the laundry liquid dispensing chamber 334, and the first sub-cover 3351 is provided with a vent 40 that communicates with the laundry liquid dispensing chamber 334. In this way, communication between the laundry liquid dispensing chamber 334 and the atmosphere can be achieved by utilizing the vent 40, which is advantageous for achieving the siphon effect of the mixed liquid by the siphon structure. Here, the laundry liquid dispensing port 50 may be provided in the first sub-cover 3351.

[0031] In some embodiments, as shown in Figures 2 and 3, there are multiple ventilation holes 40, and the multiple ventilation holes 40 are arranged in a matrix. The advantage of this is that, if the arrangement area does not change, the diameter of the ventilation holes 40 can be reduced, thereby preventing foreign objects from entering the washing liquid filling chamber 334. Furthermore, because the diameter of the ventilation holes 40 is small, it is possible to avoid exposing components inside the washing liquid filling chamber 334 to the outside.

[0032] In some embodiments, the laundry liquid dispensing chamber 334 may include a plurality of partitioned subchambers, for example, three chambers for dispensing detergent, fabric softener, and disinfectant, respectively, and this disclosure is not limited thereto.

[0033] In some embodiments, referring to Figures 2 and 3, the cover 335 may include a second sub-cover 3352, and the siphon cap 333 is connected to the second sub-cover 3352. This allows for the attachment of the second sub-cover 3352 while simultaneously mounting the siphon cap 333 to the siphon tube 332. Since the second sub-cover 3352 is located above the mixing chamber 331 and the water inlet 10 is provided on the second sub-cover 3352, the molding of the water inlet 10 becomes easier.

[0034] In some embodiments, the cover 335 is removably connected to the projection 32. This facilitates the removal and replacement of the cover 335, and also allows the user to clean any residual liquid in the washing liquid dispensing chamber 334 and the mixing chamber 331 once the cover 335 is removed. In some embodiments, the cover 335 and the projection 32 can engage with each other. For example, one of the cover 335 and the projection 32 may be provided with an engaging snap, and the other with an engaging groove. The engagement between the engaging snap and the engaging groove can be used to achieve engagement between the cover 335 and the projection 32. Of course, the cover 335 and the projection 32 may be connected to each other by fasteners, and this is not particularly limited in this disclosure.

[0035] In some embodiments of the present disclosure, referring to Figures 2 and 4, the projection 32 has a first side and a second side that are opposite each other in the axial direction of the door assembly 3, the first side being connected to the door body 31 and the second side being provided with an outlet 20. In this way, since the second side is closer to the interior of the second drum 2 than the first side, such a configuration can further ensure that the mixed liquid flowing out of the outlet 20 flows into the interior of the second drum 2.

[0036] In some embodiments of this disclosure, referring to Figure 1, the second drum 2 may be located to the upper right of the first drum 1. This facilitates the user from removing clothes from the second drum 2. Of course, in other embodiments, the second drum 2 may be located to the upper left, lower left, or lower right of the first drum 1, and this disclosure is not particularly limited thereto.

[0037] In some embodiments of this disclosure, the door assembly 3 may be positioned on the first drum 1. This allows for manual dispensing of the washing liquid into the first drum 1.

[0038] While preferred embodiments of the present disclosure have been described in detail above with reference to the drawings, the present disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical idea of ​​the present disclosure, various simple modifications can be made to the technical ideas of the present disclosure, and all such simple modifications are covered within the scope of the present disclosure.

[0039] Furthermore, the various technical features described in the specific embodiments above can be combined in any suitable manner, as long as they do not contradict each other. To avoid unnecessary repetition, this disclosure will not further describe the various possible combinations.

[0040] Furthermore, each embodiment of this disclosure can be combined in any way, and such combinations should also be considered as part of the disclosure, provided they do not contradict the spirit of this disclosure. [Explanation of Symbols]
