[0020] The terms "inner" and "outer" refer to the inside and outside of the contour of the corresponding structure. Also, the terms "first", "second", etc. used are for distinguishing one element from another and do not have an order or importance. In the description referring to the drawings, the same reference numerals in different drawings represent the same elements.
[0021] In the description of the present disclosure, it should also be noted that the terms "installation", "connection", "coupling", and "attachment" should be understood in a broad sense unless there are specific explicit regulations or limitations. For example, it may be a fixed connection, a detachable connection, an integral connection, a direct connection, or an indirect connection via an intermediate medium. The specific meaning of the above terms in the present disclosure can be understood by those skilled in the art according to the situation.
[0022] As already described, in the related art, how to arrange the washing drum and other components in the limited space inside the clothing washing device has been a research direction.
[0023] In view of this, as shown in FIGS. 1 to 4, the present disclosure provides a clothing washing device 100, which includes a housing 10 and a first drum 20. The first drum 20 is provided inside the housing 10, and a clothing inlet / outlet 111 corresponding to the opening of the first drum 20 is provided on the front panel 11 of the housing 10. Here, the dimension of the first drum 20 in the front-rear direction of the housing 10 is a first dimension L1, the dimension of the housing 10 in the front-rear direction is a second dimension L2, and the range of the ratio of the first dimension L1 to the second dimension L2 is 1 / 10 to 2 / 3.
[0024] In the present disclosure, the above first dimension L1 may be the distance from the bottom of the drum of the first drum 20 to the opening of the first drum 20 in the front-rear direction of the housing 10, or the first dimension L1 may be the distance from the bottom of the drum of the first drum 20 to the opening of the first drum 20 in the front-rear direction of the housing 10, or the first dimension L1 may be the distance from the bottom of the drum of the first drum 20 to the clothing inlet / outlet 111 of the housing 10 in the front-rear direction of the housing 10, and is not limited in the present disclosure.
[0025] The drum bottom of the first drum 20 may be the outer bottom surface of the outer tub of the first drum 20 (i.e., the outer bottom surface far from one side of the front panel 11 of the outer tub of the first drum 20), or the drum bottom of the first drum 20 may be the inner bottom surface of the inner drum of the first drum 20, and the present disclosure is not limited thereto.
[0026] In the above-described clothing washing machine 100, the housing 10 can be used as an external casing of the clothing washing machine 100. The housing 10 can be used to accommodate various components within the clothing washing machine 100, and can also support and fix some components (such as a washing drum, etc.) within the clothing washing machine 100.
[0027] In the above-described clothing washing machine 100, the first drum 20 may be the drum body of the clothing washing machine 100, and the first drum 20 may be provided within the housing 10. The first drum 20 can be used to accommodate the clothing to be washed, and depending on the arrangement of the clothing washing machine 100, operations such as washing and drying the clothing to be washed accommodated within the first drum 20 can be performed.
[0028] When the above-described clothing washing machine 100 is used for clothing washing, the user can put the clothing to be washed into the first drum 20 or take out the clothing to be washed from the first drum 20 through the clothing access opening 111 provided on the front panel 11 of the housing 10, and it is easy to take in and out the clothing to be washed.
[0029] According to the above technical proposal, the ratio of the front-to-back dimensions of the housing 10 to the front-to-back dimensions of the housing 10 is in the range of 1 / 10 to 2 / 3. In other words, by rationally designing the dimensions of the first drum 20 and the housing 10 in order to maintain a gap between the rear end of the first drum 20 and the rear end of the housing 10 in the front-to-back direction of the housing 10, a storage space 30 for accommodating other components inside the washing machine 100 (e.g., electronic control board, drying mechanism, etc.) can be formed between the rear end of the first drum 20 and the housing 10, which is advantageous for the arrangement of the washing drum and other components inside the washing machine 100, and the washing machine 100 is highly compact. The space at the rear of the housing 10, the depth and volume of the drum, for example, the depth and volume of the first drum 20 are all balanced, ensuring efficient use of space and facilitating user operation and loading and unloading of clothes.
[0030] Selectively, the ratio of the first dimension L1 to the second dimension L2 is in the range of 1 / 3 to 2 / 3. Since the ratio of the first dimension L1 to the second dimension L2 is in the range of 1 / 3 or more, the first drum 20 can have a long dimension along the front-to-back direction, and the first drum 20 having a long dimension can have a large volume, allowing the first drum 20 to accommodate a certain volume of laundry, thus meeting the washing needs of the first drum 20 and improving the washing rate.
[0031] Furthermore, since the ratio of the first dimension L1 to the second dimension L2 is 2 / 3 or less, the dimensions of the first drum 20 do not become too long in the front-to-back direction. On the other hand, by rationally designing the dimensions of the first drum 20 and the housing 10 in the front-to-back direction, a large storage space 30 can be provided between the first drum 20 and the housing 10, making it easy to arrange other parts inside the washing machine 100. On the other hand, the first drum 20 is not formed as a long, narrow drum, making it easy for the user to put clothes to be washed into the first drum 20 and to take clothes to be washed out of the first drum 20.
[0032] In this disclosure, the first drum 20 can have any suitable dimensions in the front-to-back direction of the housing 10, and is not limited thereto. In one embodiment of this disclosure, the range of the first dimension L1 is 200 mm to 300 mm. A first drum 20 with a first dimension L1 greater than 200 mm can have a large volume, allowing it to accommodate a certain volume of laundry, thus meeting the washing needs of the washing machine 100 and facilitating the user to remove the laundry.
[0033] The ratio of the first dimension L1 to the second dimension L2 is in the range of 1 / 3 to 3 / 5, and the range of the first dimension L1 is 200 mm to 300 mm. Therefore, in the front-to-back direction, the second dimension L2 of the housing 10 may be 500 to 600 mm. In other words, the dimensions of the housing 10 can be the same as those of a standard housing 10, which is advantageous for the placement of the washing machine 100 in the user's home. This ratio range and the first dimension L1 allow for a balance between washing volume, ease of removing clothes, and the use of space behind the first drum 20.
[0034] Furthermore, if the first dimension L1 is smaller than 300 mm, the first drum 20 is not formed as a long, narrow drum, which is advantageous for the user when placing clothes to be washed into or removing them from the first drum 20.
[0035] To facilitate the storage of clothes to be washed, a first inner drum 21 for storing clothes is selectively provided inside the first drum 20, as shown in Figure 4, and the depth of the first inner drum 21 is 140 mm to 200 mm. In this way, the first drum 20 can provide sufficient storage space 30 for clothes to be washed in order to facilitate the washing and / or drying of the clothes to be washed.
[0036] In this disclosure, the volume of the first inner drum 21 is not limited, and the first inner drum 21 only needs to be able to meet the washing needs of the clothes washing machine 100. In one embodiment of this disclosure, the volume of the first inner drum 21 may be 1.5L to 4.5L.
[0037] Here, the volume of the first inner drum 21 mentioned above is the maximum capacity of laundry that can be stored in the first drum 20. For example, this volume may be the maximum capacity of liquid that can be stored in the first drum 20 when the inner drum of the first drum 20 closes the drum door (i.e., the door seal mentioned above).
[0038] Since the volume of the first inner drum 21 is 1.5L or more, the first drum 20 can accommodate a large amount of clothing, satisfying the user's need to wash and dry large quantities of laundry at once.
[0039] Furthermore, since the volume of the first inner drum 21 is 4.5L or less, the volume of the first drum 20 is not too large, and it is possible to effectively avoid a situation where the volume of the first drum 20 becomes too large, making it difficult to arrange the first drum 20 and other parts inside the washing machine 100 inside the washing machine 100.
[0040] Selectively, the volume of the first inner drum 21 described above is 3L.
[0041] Furthermore, this disclosure does not limit the specific range of the diameter of the first drum 20, and in one embodiment of this disclosure, the diameter of the first drum 20 may be 150 mm to 200 mm. A first drum 20 with a diameter of 150 mm or more can have a large volume and can accommodate a large amount of clothing, thus meeting the user's need to wash and dry a large amount of laundry at once.
[0042] Furthermore, even with a first drum 20 having a diameter of 200 mm or less, the volume of the first drum 20 is not excessively large, and the smaller volume of the first drum 20 makes it easier to arrange the first drum 20 and other components within the washing machine 100 inside the housing 10.
[0043] In this disclosure, the first drum 20 may be positioned in any direction within the housing 10 as long as it can satisfy the washing needs of the clothes to be washed. For example, the first drum 20 may be positioned horizontally within the housing 10, or it may be positioned diagonally within the housing 10, and is not limited to these positions. In one embodiment of this disclosure, as shown in Figures 1, 2, and 4, the first drum 20 extends horizontally along the front-to-back direction of the housing 10. In other words, the first drum 20 is positioned horizontally within the housing 10. On the one hand, the horizontally positioned first drum 20 can distribute the clothes to be washed evenly within the first drum 20 by gravity, thereby improving the washing effect of the clothes. On the other hand, the horizontally positioned first drum 20 is structurally stable, which is advantageous for improving the stability and safety of the washing machine 100.
[0044] To enhance the practicality of the clothes washing machine 100, the clothes washing machine 100 may optionally further include a second drum 40, the opening of which is provided on the front side of the housing 10, as shown in Figures 1 to 4.
[0045] In this disclosure, the first drum 20 and the second drum 40 may both be a drying drum, a washing drum, or a washing-drying drum.
[0046] For example, if the first drum 20 is a washing drum, the first drum 20 can have a washing function and can wash the clothes to be washed inside the first drum 20.
[0047] If the first drum 20 is a washer-dryer drum, the first drum 20 can have both a washing function and a drying function, and the first drum 20 can wash and dry the clothes to be washed inside the first drum 20.
[0048] Similarly, if the second drum 40 is a washing drum, the second drum 40 can have a washing function and can wash the clothes to be washed inside the second drum 40.
[0049] If the second drum 40 is a washer-dryer drum, the second drum 40 can have both a washing function and a drying function, and the second drum 40 can wash and dry the clothes to be washed inside the second drum 40.
[0050] The above-described washing machine 100 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 20 and the second drum 40.
[0051] In this disclosure, the structure of the housing 10 is not limited, and the housing 10 may be an integrally formed housing 10 or a housing 10 assembled from multiple panels. In one embodiment of this disclosure, as shown in Figures 1 to 4, the housing 10 includes a front panel 11 and a rear panel 12 spaced apart in the front-rear direction, and the openings for the first drum 20 and the second drum 40 are both provided in the front panel 11. In this way, clothes to be washed can be loaded and unloaded through the front panel 11, and the aesthetic appearance of the washing machine 100 is enhanced.
[0052] Furthermore, the front panel 11 and the rear panel 12 can jointly enclose the space for mounting the first drum 20 and the second drum 40, and the front panel 11 and the rear panel 12 can serve to protect the components located inside the housing 10.
[0053] In this disclosure, the second drum 40 may be positioned in any direction within the housing 10 as long as it can satisfy the washing needs of the clothes to be washed. For example, the second drum 40 may be positioned horizontally within the housing 10, or diagonally within the housing 10, and is not limited to these positions. In one embodiment of this disclosure, as shown in Figures 1, 3, and 4, the second drum 40 extends horizontally along the front-to-back direction of the housing 10. In other words, the second drum 40 is positioned horizontally within the housing 10. On the one hand, the horizontally positioned second drum 40 can distribute the clothes to be washed evenly within the second drum 40 by gravity, thereby improving the washing effect of the clothes. On the other hand, the horizontally positioned second drum 40 is structurally stable, which is advantageous for improving the stability and safety of the washing machine 100.
[0054] In this embodiment, where the clothes washing machine 100 includes a first drum 20 and a second drum 40, the first drum 20 and the second drum 40 may both be positioned diagonally within the housing 10, or they may both be positioned horizontally within the housing 10; however, this disclosure is not limited to such arrangements.
[0055] Furthermore, this disclosure does not limit the specific placement positions of the first drum 20 and the second drum 40 within the housing 10. In one embodiment of this disclosure, as shown in Figures 1 to 4, the first drum 20 is located above the second drum 40, and the first drum 20 and the second drum 40 are offset in the width direction of the housing 10. In other words, the first drum 20 is provided above the side of the second drum 40. By rationally setting the relative positions of the first drum 20 and the second drum 40 in this way, the requirements for the center of gravity balance of the clothes washing machine 100 can be met, improving the stability and safety of the clothes washing machine 100 and reducing vibrations of the clothes washing machine 100.
[0056] This disclosure does not limit the specific dimensions of the first drum 20 and the second drum 40. In one embodiment of this disclosure, the diameter of the second drum 40 may be larger than the diameter of the first drum 20. Because the diameter of the second drum 40 is larger than that of the first drum 20, the capacity of the second drum 40 is larger than that of the first drum 20. Thus, by reducing the diameter of the first drum 20, a larger mounting space can be secured for the second drum 40, and the second drum 40 can meet the need for large capacity storage.
[0057] For example, the second drum 40 may be a main washing drum for washing adult clothes and outerwear, and the first drum 20 may be a small washing drum for washing underwear or infant clothes.
[0058] In embodiments where the diameter of the second drum 40 is larger than the diameter of the first drum 20, the second drum 40 may be located below and to the side of the first drum 20. By positioning the second drum 40, which has a larger mass, below and to the side of the first drum 20, the center of gravity of the washing machine 100 can be lowered, which is advantageous in improving the stability of the washing machine.
[0059] This disclosure does not limit the specific dimensions of the second drum 40, and in one embodiment of this disclosure, the diameter of the second drum 40 may be 500 mm to 545 mm. In this way, the second drum 40 can meet the need for large-capacity storage and, consequently, can store a reasonable amount of laundry.
[0060] In this disclosure, the specific type of clothes washing machine 100 is not limited. For example, in one embodiment of this disclosure, the clothes washing machine 100 may be a washing machine such as a drum-type washing machine, and in another embodiment of this disclosure, the clothes washing machine 100 may be a dryer, a washer-dryer, or the like.
[0061] 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.
[0062] Furthermore, each specific technical feature described in the above specific embodiments can be combined in any suitable manner as long as they do not contradict each other, and in order to avoid unnecessary duplication, various possible combinations are not described separately in this disclosure.
[0063] Furthermore, various different embodiments of this disclosure can be combined in any way and should be considered in the same manner as the disclosures, as long as they do not contradict the spirit of this disclosure. [Explanation of symbols]
