[0020] It should also be noted that, in the descriptions in this disclosure, the terms “installation,” “connection,” “linking,” and “attachment” should be understood broadly unless otherwise explicitly specified or limited. For example, a connection may be fixed, removable, integral, direct, or indirectly connected via an intermediate medium. The specific meaning of the above terms in this disclosure will be understood by those skilled in the art depending on the context.
[0021] As already mentioned, in related technologies, how to arrange the washing drum and other components within the limited space inside a washing machine is an important area of research in this field.
[0022] In view of this, as shown in FIGS. 1 to 3, the present disclosure provides a laundry appliance, comprising a housing 30, a first drum 10 and a second drum 20, wherein the first drum 10 and the second drum 20 are provided within the housing 30, and a first opening 11 and a second opening 21 are provided on a front panel 31 of the housing 30. Here, the first opening 11 and the second opening 21 are clothing input ports located on the front panel 31. The first opening 11 is connected to an opening of the first drum 10 (i.e., an opening for taking in and out clothing in the first drum 10), and the second opening 21 is connected to an opening of the second drum 20 (i.e., an opening for taking in and out clothing in the second drum 20). That is, the first opening 11 corresponds to the position of the opening of the first drum 10 on the front panel 31, and the second opening 21 corresponds to the position of the opening of the second drum 20 on the front panel 31. A door panel for opening and closing the first opening 11 can be provided at both the first opening 11 and the second opening 21. The included angle θ between the line connecting the centers of the first opening 11 and the second opening 21 and the horizontal direction is 45° to 85°. The center of the first opening 11 may be the intersection of the axis of the first drum 10 and the first opening 11. When the first opening 11 is circular, the center of the first opening 11 can be the center of the circle of the first opening 11.
[0023] In the above laundry appliance, the housing 30 can be used as an external casing of the laundry appliance. The housing 30 can be used to accommodate various components within the laundry appliance, and can also support and fix some components within the laundry appliance (such as a washing drum, etc.).
[0024] In the above laundry appliance, the first drum 10 and the second drum 20 can be used to accommodate the laundry to be washed. Depending on the arrangement of the laundry appliance, operations such as washing and drying the laundry accommodated in the first drum 10 and the second drum 20 can be performed.
[0025] According to the above technical proposal, setting the angle between the line connecting the center of the first opening 11 and the center of the second opening 21 and the horizontal direction to 45° to 85° corresponds to the first drum 10 and the second drum 20 being positioned offset from each other in the height direction and left-right direction (width direction) of the washing machine. This is advantageous because it allows the first drum 10 and the second drum 20 to be positioned in a reasonable location within the housing 30. Furthermore, after the first drum 10 and the second drum 20 are positioned within the housing 30, a large storage space can be created for accommodating other components within the washing machine (e.g., electronic control board, drying mechanism, etc.). The center of the first opening 11 and the center of the second opening 21 can be spaced appropriately in the left-right direction of the housing 30, and the center of the first opening 11 and the center of the second opening 21 can be spaced appropriately in the height direction of the housing 30, which is advantageous in balancing the weight of the washing machine on the one hand, reducing vibrations during operation of the washing machine on the other hand, reducing or avoiding interference between the door panel of the first opening 11 and the door panel of the second opening 21, and also advantageous in reducing or avoiding shielding of the second opening 21 by the door panel of the first opening 11 and shielding of the first opening 11 by the door panel of the second opening 21.
[0026] Optionally, the included angle θ between the line connecting the centers of the first opening 11 and the second opening 21 and the horizontal direction may be 55° to 65°. For example, the included angle θ between the line connecting the centers of the first opening 11 and the second opening 21 and the horizontal direction may be 60°. In this way, while ensuring a compact structure of the clothing washing device, the weight balance of the clothing washing device is improved, the vibration during the operation of the clothing washing device is further reduced, the shielding of the door panel of the first opening 11 and the door panel of the second opening 21 is further reduced or avoided, the interference between the door panel of the first opening 11 and the door panel of the second opening 21 is further reduced or avoided, and it is advantageous to further reduce or avoid the shielding of the second opening 21 by the door panel of the first opening 11 and the shielding of the first opening 11 by the door panel of the second opening 21. Considering the limited space of the housing 30, if the included angle θ is within the range of 55° to 65°, more space can be ensured for the first drum 10 and the second drum 20 while ensuring the balance of the housing 30. Thereby, the volumes of the first drum 10 and the second drum 20 can be increased, and the cleaning rate of the clothing washing device (i.e., the washing machine) can be improved.
[0027] In addition, in the present disclosure, the first drum 10 and the second drum 20 may each be any one of a drying drum, a washing drum, and a washing and drying drum.
[0028] For example, when the first drum 10 is a washing drum, the first drum 10 can have a washing function, and the first drum 10 can wash the clothing to be washed within the first drum 10.
[0029] When the first drum 10 is a washing and drying drum, the first drum 10 can have both a washing function and a drying function, and the first drum 10 can wash and dry the clothing to be washed within the first drum 10.
[0030] Similarly, when the second drum 20 is a washing drum, the second drum 20 can have a washing function, and the second drum 20 can wash the clothing to be washed within the second drum 20.
[0031] If the second drum 20 is a washer-dryer drum, the second drum 20 can have both a washing function and a drying function, and the second drum 20 can wash and dry the clothes to be washed inside the second drum 20.
[0032] The above-described washing machine may have the functions of single-drum washing (for example, one drum for washing outer garments and the other drum for washing underwear), single-drum drying, or integrated washing and drying by combining the functions of the first drum 10 and the second drum 20.
[0033] In this disclosure, the structure of the housing 30 is not limited, and the housing 30 may be an integrally formed housing 30 or a housing 30 assembled from multiple panels. As shown in Figures 1 to 3, the housing 30 includes a front plate 31 and a rear plate 32 spaced apart in the front-to-back direction of the housing, a left plate 33 and a right plate 34 spaced apart in the left-to-right direction of the housing, and a top plate 35 and a bottom plate 36 spaced apart in the up-to-down direction of the housing. Here, the openings of the first drum 10 and the second drum 20 are both provided in the front plate 31, thereby allowing clothes to be loaded and unloaded through the front plate 31, and enhancing the aesthetic appearance of the washing machine.
[0034] Furthermore, the front panel 31, rear panel 32, left panel 33, right panel 34, and top panel 35 can jointly enclose the space for mounting the first drum 10 and the second drum 20. Here, the front panel 31 is the front panel of the housing, and the front panel 31, rear panel 32, left panel 33, right panel 34, top panel 35, and bottom panel 36 can serve to protect the components installed inside the housing 30.
[0035] In this disclosure, the first drum 10 and the second drum 20 may be arranged in any direction within the housing 30 as long as they can satisfy the washing needs of the clothes to be washed. For example, at least one of the first drum 10 and the second drum 20 may extend horizontally along the front-to-back direction of the housing 30, or at least one of the first drum 10 and the second drum 20 may extend horizontally along the front-to-back direction of the housing 30, and this is not limited to this disclosure. In one embodiment of this disclosure, as shown in Figure 1, at least one of the first drum 10 and the second drum 20 extends horizontally along the front-to-back direction of the housing 30, in other words, the first drum 10 and the second drum 20 are arranged horizontally within the housing 30. On the one hand, the horizontally positioned first drum 10 and second drum 20 allow the clothes to be washed to be evenly distributed within the first drum 10 and second drum 20 by gravity, thereby improving the washing effect of the clothes. On the other hand, the horizontally positioned first drum 10 and second drum 20 are structurally stable, which is advantageous in improving the stability and safety of the washing machine.
[0036] In another embodiment of the present disclosure, at least one of the first drum 10 and the second drum 20 is positioned at an angle, such that the height of the front end of the opening of the first drum 10 is higher than the height of the rear end of the first drum 10, and / or the height of the front end of the opening of the second drum 20 is higher than the height of the rear end of the second drum 20. In this way, it becomes easier for the user to put clothes in and take them out of the first drum 10 or the second drum 20 in a more natural posture.
[0037] In this disclosure, the dimensional relationship between the first drum 10 and the second drum 20 is not limited. In one embodiment of this disclosure, as shown in Figure 1, the diameter of the second drum 20 is larger than the diameter of the first drum 10. Because the diameter of the second drum 20 is larger than the diameter of the first drum 10, the capacity of the second drum 20 may be larger than that of the first drum 10. In this way, by reducing the diameter of the first drum 10, more mounting space can be secured for the second drum 20, and the second drum 20 can meet the need for large capacity storage.
[0038] For example, the second drum 20 may be a main washing drum for washing adult clothes and outerwear, and the first drum 10 may be a small washing drum for washing underwear or infant clothes.
[0039] Selectively, as shown in Figure 1, the first drum 10 may be positioned above the second drum 20, that is, the first drum 10 may be positioned above the second drum 20 and offset from the second drum 20 in the width direction of the washing machine, in other words, the second drum 20 may be positioned below the first drum 10. By positioning the second drum 20, which has a larger mass, below the first drum 10, the center of gravity of the entire washing machine can be lowered, which is advantageous in improving the stability of the washing machine.
[0040] In this disclosure, the specific dimensions of the first drum 10 and the second drum 20 are not limited. In one embodiment of this disclosure, the diameter of the first drum 10 may be 150 mm to 200 mm, and / or the diameter of the second drum 20 may be 500 mm to 545 mm. In this way, there is an advantage in being able to make the washing machine relatively compact while maintaining good functionality for both the first drum 10 and the second drum 20.
[0041] Selectively, the diameter of the first drum 10 may be 175mm to 185mm, and / or the diameter of the second drum 20 may be 533mm to 543mm. In this way, there is an advantage in being able to make the washing machine relatively compact while ensuring good functionality for both the first drum 10 and the second drum 20.
[0042] In this disclosure, the distance between the center of the first opening 11 and the center of the second opening 21 is not limited, and in one embodiment of this disclosure, the length of the line connecting the center of the first opening 11 and the center of the second opening 21 may be 345 mm to 760 mm. Selectively, the length of the line connecting the center of the first opening 11 and the center of the second opening 21 may be 367 mm to 377 mm. This is advantageous in reducing or avoiding interference between the door panel of the first opening 11 and the door panel of the second opening 21 when opening and closing, and in preventing the door panel of the first opening 11 from blocking the second opening 21, and the door panel of the second opening 21 from blocking the first opening 11. It is also advantageous in reducing the transmission and superposition between the vibration of the second drum 20 and the vibration of the first drum 10.
[0043] Selectively, as shown in Figures 2 and 3, the first drum 10 is positioned above the second drum 20, and the washing machine further comprises a display panel component 50 attached to the upper end of the front panel 31, where the distance between the lower end surface of the display panel component 50 and the center of the first opening 11 is a first distance L1, and the range of the first distance L1 is 70 mm to 110 mm.
[0044] In this way, a reasonable gap can be maintained between the lower end of the display panel component 50 and the first drum 10, ensuring the correct mounting of the display panel component 50 without interfering with the mounting of the first drum 10, thereby preventing mounting problems such as interference between the display panel component 50 and the first drum 10. In this way, the space utilization rate of the washing machine is increased, the compactness of the washing machine is enhanced, the placement of other parts of the washing machine is made easier, and the placement of the display panel component 50 is also made easier.
[0045] Selectively, the range of the first distance L1 may be 80 mm to 100 mm, for example, the first distance L1 may be 90 mm. In this way, the space utilization rate of the clothes washing machine can be further increased, the compactness of the clothes washing machine can be further increased, the arrangement of other parts of the clothes washing machine can be further facilitated, and the arrangement of the display panel component 50 can also be further facilitated.
[0046] In this disclosure, the distance between the top plate 35 of the housing 30 and the center of the first opening 11 is not limited. In one embodiment, as shown in Figure 3, the first drum 10 is located above the second drum 20, where the distance between the top plate 35 of the housing 30 and the center of the first opening 11 is the second distance L2, and the range of the second distance L2 is 95 mm to 150 mm.
[0047] In this way, a reasonable gap can be maintained between the top plate 35 and the first drum 10, ensuring that the top plate 35 does not interfere with the first drum 10, and also does not interfere with the mounting of the first drum 10. In this manner, the space utilization rate of the washing machine is increased, the compactness of the washing machine is enhanced, and the arrangement of other components of the washing machine can be facilitated.
[0048] Selectively, the distance between the top of the first drum 10 and the top plate 35 may be in the range of 20 mm to 50 mm, for example, the distance between the top of the first drum 10 and the top plate 35 may be 33 mm.
[0049] In this disclosure, the distance between the left and right plates 33 and 34 of the housing 30 and the center of the first opening 11 is not limited. In one embodiment, as shown in Figure 3, the first opening 11 is closer to the right plate 34 of the housing 30 than the second opening 21, and the distance from the center of the first opening 11 to the right plate 34 is 100 mm to 265 mm, for example, 114 mm. Alternatively, the first opening 11 is closer to the left plate 33 of the housing 30 than the second opening 21, and the distance from the center of the first opening 11 to the left plate 33 is 100 mm to 265 mm. In this way, a reasonable gap can be maintained between the left and right plates 33 and 34 and the first drum 10, ensuring that the left and right plates 33 and 34 do not interfere with the first drum 10, and that they do not interfere with the mounting of the first drum 10. In this way, the space utilization rate of the washing machine is increased, the compactness of the washing machine is improved, and the arrangement of other parts of the washing machine can be facilitated.
[0050] Although preferred embodiments of the present disclosure have been described in detail above with reference to the attached drawings, the present disclosure is not limited to the specific contents of the embodiments described above. Within the scope of the technical idea of the present disclosure, various simple modifications are possible, and all of these simple modifications fall within the scope of the present disclosure.
