Abstract

[Challenge] To meet user needs in laundry and improve laundry efficiency. [Solution] The washing machine includes a casing, a first drum and a second drum provided within the casing, wherein the diameter of the first drum is larger than the diameter of the second drum, and the ratio of the diameters of the first drum to the diameter of the second drum is 1.2 to 4. By providing the first and second drums within the casing, the user can select and use the first drum and/or the second drum as needed, satisfying the user's need to use separate drums and improving washing efficiency. Furthermore, the different sizes of the first and second drums can satisfy the user's different clothing washing needs. In addition, by setting the ratio of the diameters of the first and second drums to 1.2 to 4, the first and second drums can effectively utilize the space within the casing, improving the compactness of the structural design.

Description

This disclosure relates to the field of home appliance technology, and more particularly to washing machines. With the rapid advancement of science and technology, many washing machines equipped with washing functions have become indispensable appliances in people's daily lives. Single-drum washing machines are favored by users because they can meet the basic needs of household use. However, in related technologies, single-drum washing machines have only one drum and a single function, thus failing to meet the user's need to wash clothes using separate drums. The drawings herein are incorporated into the specification and constitute part of this specification, illustrating embodiments consistent with the present disclosure and are used together with the specification to illustrate the principles of the embodiments of this disclosure. This is a schematic perspective view showing a partial structure of a washing machine according to an exemplary embodiment, in which the first drum shown in this figure is located in the central part of the housing in a first direction, and a second drum is provided, located diagonally above the first drum. This is a schematic front view of a washing machine according to an exemplary embodiment, in which the first drum shown in this figure is located in the center of the housing in a first direction, and one second drum is provided, which is located diagonally above the first drum. This is a schematic front view of a washing machine according to an exemplary embodiment, in which the first drum shown in this figure is located in the central part of the housing in a first direction, and two second drums are provided, with the two second drums located diagonally above and to the left of the first drum in a first direction. This is a schematic side view of a washing machine according to an exemplary embodiment, in which both the first axis of the first drum and the second axis of the second drum extend along the second direction. This is a schematic side view of a washing machine according to an exemplary embodiment, in which the first axis of the first drum in this figure extends along the second direction, and the second axis of the second drum extends along the third direction. Hereinafter, exemplary embodiments are described in detail, and examples are shown in the drawings. Where the following description relates to the drawings, unless otherwise stated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the present disclosure, which are described in detail in the appended claims. In this disclosure, unless otherwise specified, directional terms such as "inside" and "outside" refer to the inside and outside of a specific structural contour; directional terms such as "up," "down," "front," "back," "left," and "right" refer to the "up," "down," "front," "back," "left," and "right" as defined when the washing machine is in normal use (see Figure 1 for specific examples); the directional term "first direction" may be the same as the left-right direction; the directional term "second direction" may be the same as the front-back direction (see Figure 1 for specific examples); the directional term "third direction" may be the same as Figure 5 for specific examples; and the terms "first" and "second" are used solely to distinguish one element from another and have no order or importance. Referring to Figures 1-5, this disclosure provides a washing machine comprising a housing 1, a first drum 2 and a second drum 3 located within the housing 1, wherein the diameter of the first drum 2 is greater than the diameter of the second drum 3, and the ratio of the diameters of the first drum 2 to the second drum 3 is between 1.2 and 4. In the above proposed technology, firstly, by providing a first drum 2 and a second drum 3 within the housing 1, the user can select and use the first drum 2 and/or the second drum 3 as needed, satisfying the user's need to use separate drums and improving washing efficiency. Secondly, the diameter of the first drum 2 is larger than the diameter of the second drum 3, meaning that the dimensions of the first drum 2 and the second drum 3 are different, allowing the different sizes of the first and second drums 3 to meet the user's different clothing washing needs. Furthermore, by setting the ratio of the diameter of the first drum 2 to the diameter of the second drum 3 to 1.2 to 4, the first drum 2 and the second drum 3 can effectively utilize the space within the housing 1, improving the compactness of the structural design. Moreover, according to this ratio, the dimensional combination of the first drum 2 and the second drum 3 ensures that the two drums cooperate with each other within the housing 1, preventing
