[0037] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention.
[0038] As Figure 1 shown, the washing machine according to the embodiment of the present invention includes a drying channel 1 and a fan 2.
[0039] The drying channel 1 is provided with a plurality of air inlets 11, and at least two air inlets 11 are located on different sides of the drying channel 1. For example, as Figure 1As shown, the drying tunnel 1 can generally be a flat tubular structure. A part of the drying tunnel 1 can extend in the front-rear direction, and a plurality of air inlets 11 can be provided on the side walls of this part of the drying tunnel 1. For example, the number of air inlets 11 can be two, three, four, etc. The plurality of air inlets 11 can be arranged at intervals along the circumferential direction of the drying tunnel 1, and the plurality of air inlets 11 can be located on the left side wall, right side wall, top wall, etc. of the drying tunnel 1 respectively.
[0040] The fan 2 is connected to the drying tunnel 1 or is provided inside the drying tunnel 1, and the fan 2 is used to generate a negative pressure inside the drying tunnel 1 so that the drying tunnel 1 can simultaneously suck in air through the plurality of air inlets 11. For example, the fan 2 can also be directly installed inside the drying tunnel 1, that is, a part of the drying tunnel 1 can be regarded as the housing of the fan 2, and the fan 2 can be arranged adjacent to the air inlet 11 on the drying tunnel 1. In some other embodiments, the drying tunnel 1 can also be separately provided. At this time, the housing of the fan 2 can be connected between two drying tunnels 1.
[0041] When the fan 2 operates, a negative pressure can be generated inside the drying tunnel 1. At this time, the external gas can be simultaneously sucked into the drying tunnel 1 through the above-mentioned plurality of air inlets 11 under the action of the negative pressure, thus meeting the use requirements of air intake.
[0042] In the washing machine according to the embodiment of the present invention, the drying tunnel 1 is provided with a plurality of air inlets 11, and these air inlets 11 are located on different sides of the drying tunnel 1. Compared with the situation in the prior art where only one air inlet 11 is provided, the overall air intake volume (air suction volume) is greatly improved, thereby playing a role in increasing the drying air volume, and further playing a role in shortening the drying time and improving the drying efficiency.
[0043] Secondly, the arrangement of the plurality of air inlets 11 can realize simultaneous air intake in different directions. Such a design is beneficial to the uniformity of the overall force of the drying tunnel 1, and further can also play a role in reducing vibration and noise, thereby improving the user experience of customers.
[0044] In some embodiments, a filtering component for filtering impurities in the air flow is provided at the air inlet 11. For example, a filtering component can be installed at each air inlet 11. The filtering component can include structural components such as a filter screen. Thus, the situation where impurities such as lint enter the fan 2 can be avoided, and further the situation where the impurities adhere to the fan 2 and easily reduce the operating performance of the fan 2 can be avoided.
[0045] In some embodiments, aromatherapy is provided inside the drying tunnel 1 and / or at least part of the air inlets 11. For example, aromatherapy can be provided at each air inlet 11. The molecules volatilized by the aromatherapy can flow with the air flow and can play a role in removing odors and freshening clothes, etc., thereby improving the overall drying effect.
[0046] In some other embodiments, aromatherapy can also be provided inside the drying tunnel 1.
[0047] In some embodiments, the washing machine includes a first cylinder body 3, a drying duct 1 is disposed beside the first cylinder body 3 and includes an extension section 12 extending along the axial direction of the first cylinder body 3, a plurality of air inlets 11 and a blower 2 are both disposed on the extension section 12, and at least two air inlets 11 are oppositely arranged in the interval direction between the extension section 12 and the first cylinder body 3.
[0048] For example, as Figure 1 shown, the first cylinder body 3 can be in a cylindrical shape, and the rotation axis of the first cylinder body 3 can extend along the front-rear direction. The drying duct 1 can be disposed on the left side of the first cylinder body 3, a part of the drying duct 1 can be in a flat tubular structure and form the above-mentioned extension section 12, the extension section 12 can extend along the front-rear direction, and the extension section 12 and the first cylinder body 3 are spaced apart in the left-right direction.
[0049] As Figure 1 shown, there can be two air inlets 11, both of the two air inlets 11 can be disposed on the extension section 12 and adjacent to the front end of the extension section 12, one of the air inlets 11 can be disposed on the left side of the extension section 12, and the other air inlet 11 can be disposed on the right side of the extension section 12. Thus, the compactness of the overall structure layout can be improved.
[0050] In some embodiments, the washing machine includes a first cylinder body 3, a second cylinder body 4, a first drying system 5 and a second drying system 6.
[0051] As Figure 2 shown, both the first cylinder body 3 and the second cylinder body 4 can be in a cylindrical shape, and the rotation axes of both the first cylinder body 3 and the second cylinder body 4 can extend along the front-rear direction. The radial dimension of the first cylinder body 3 is smaller than that of the second cylinder body 4, that is, the first cylinder body 3 can be a small-capacity cylinder body, so as to meet the use needs of washing underwear, baby clothes, etc., and the second cylinder body 4 is a large-capacity cylinder body, so as to meet the use needs of daily clothes.
[0052] The first drying system 5 is assembled on the first cylinder body 3 and is used for drying the clothes in the first cylinder body 3, the second drying system 6 is assembled on the second cylinder body 4 and is used for drying the clothes in the second cylinder body 4, and at least one of the first drying system 5 and the second drying system 6 includes a drying duct 1 and a blower 2.
[0053] For example, as Figure 2As shown, the washing machine may include two independent drying systems, namely the first drying system 5 and the second drying system 6 described above. The first drying system 5 may be disposed on the right side of the second drying system 6. The first drying system 5 may be the drying system described above, that is, a plurality of air inlets 11 may be provided in the drying channel of the first drying system 5, while the second drying system 6 may be an existing drying system, that is, only one air inlet 11 is provided in the drying channel of the second drying system 6.
[0054] In some other embodiments, both the first drying system 5 and the second drying system 6 may be the drying systems described above, or alternatively, only the second drying system 6 may be the drying system described above. Thus, the needs for different combinations and uses of drying functions are met.
[0055] In some embodiments, the plurality of air inlets 11 in the drying channel of the first drying system 5 include a first air inlet 52 and a second air inlet 53. The first air inlet 52 and the second air inlet 53 are arranged oppositely, and the first air inlet 52 is arranged towards the drying channel of the second drying system 6, and the second air inlet 53 is arranged towards the first cylinder 3.
[0056] For example, for the convenience of description, hereinafter the drying channel of the first drying system 5 will be referred to as the first drying channel 51. As Figure 2 shown, only two air inlets 11 may be provided in the air inlet 11 of the first drying channel 51. The two air inlets 11 are respectively the first air inlet 52 and the second air inlet 53. The first air inlet 52 may be provided on the left side wall of the first drying channel 51, and the second air inlet 53 may be provided on the right side wall of the first drying channel 51. Thus, while meeting the requirement of a large air volume supply, the symmetry of the arrangement of the air inlets 11 can be achieved, thereby ensuring the balance of the wind force distribution during the air inlet process and playing a role in vibration reduction and noise reduction.
[0057] In some embodiments, the drying channels of both the first cylinder 3 and the second drying system 6 are located above the second cylinder 4. The drying channel of the first drying system 5 is located between the drying channel of the second drying system 6 and the first cylinder 3, and the drying channel of the first drying system 5 is spaced apart from both the drying channel of the second drying system 6 and the first cylinder 3.
[0058] For the convenience of description, hereinafter the drying channel of the second drying system 6 will be referred to as the second drying channel 61. For example, as Figure 2As shown, the first drying channel 51, the second drying channel 61, and the first cylinder 3 can all be arranged above the second cylinder 4. The second drying channel 61, the first drying channel 51, and the first cylinder 3 can be arranged in sequence in the left - right direction. Among them, the second drying channel 61 is located on the left side of the first drying channel 51 and is arranged at an interval from the first drying channel 51, and the first cylinder 3 is arranged on the right side of the first drying channel 51 and is arranged at an interval from the first drying channel 51. Thus, the spatial optimization layout of the overall structure is realized, which is beneficial to improving the space utilization rate. In addition, both the first drying channel 51 and the second drying channel 61 being arranged on the top side of the first cylinder 3 can also provide convenience for operations such as maintenance.
[0059] In some embodiments, the radial dimension of the first cylinder 3 is 175 mm to 185 mm. For example, as Figure 3 shown, the radial dimension of the first cylinder 3 is the diameter d of the first cylinder 3. The diameter d can be 175 mm, 176 mm, 177 mm, 179 mm, 180 mm, 181 mm, 182 mm, 183 mm, 184 mm, 185 mm, etc. Thus, the capacity of the first cylinder 3 can be limited within a suitable range, while meeting the need to wash small - sized clothes and also limiting the overall size.
[0060] In some embodiments, the radial dimension of the second cylinder 4 is 533 mm to 543 mm. For example, as Figure 3 shown, the radial dimension of the second cylinder 4 is the diameter D of the second cylinder 4. The diameter D can be 533 mm, 534 mm, 535 mm, 536 mm, 537 mm, 538 mm, 539 mm, 540 mm, 541 mm, 543 mm, etc. Thus, the capacity of the second cylinder 4 can be limited within a suitable range, meeting the usage requirements for washing large - sized clothes.
[0061] In some embodiments, the rotation axes of the first cylinder 3 and the second cylinder 4 are arranged in parallel, and the distance between the rotation axes of the first cylinder 3 and the second cylinder 4 is 367 mm to 377 mm.
[0062] For example, as Figure 3 shown, the distance between the rotation axes of the first cylinder 3 and the second cylinder 4 can be the dimension L. The dimension L can be 367 mm, 368 mm, 369 mm, 370 mm, 371 mm, 372 mm, 373 mm, 374 mm, 375 mm, 377 mm, etc. Thus, the usage requirements for the assembly of the first cylinder 3 and the second cylinder 4 are met, avoiding the situation of easy contact due to too close a distance and also avoiding the situation of an easy increase in the overall size due to too far a distance.
[0063] In some embodiments, the washing machine includes a cabinet. An opening 71 is provided on the cabinet wall 7 of the cabinet, and at least one air inlet 11 on the drying channel 1 is communicated with the opening 71. For example, as Figure 3 and Figure 4 shown, the cabinet can be the casing of the washing machine. The cabinet wall 7 of the cabinet can specifically be the right side wall of the cabinet. An opening 71 can be provided at the top of the cabinet wall 7. The opening 71 can be a circular hole. The right side wall of the first drying channel 51 can be in contact with the left side edge of the cabinet wall 7, and the second air outlet 53 on the first drying channel 51 can be directly opposite to the opening 71 and hermetically communicated with the opening 71. During use, the gas outside the cabinet can be directly sucked into the first drying channel 51 through the opening 71 and the second air outlet 53, thereby meeting the use requirement of supplying air flow from the outside of the cabinet into the first cylinder 3.
[0064] In some other embodiments, the cabinet wall 7 can also be the left side wall, the top wall, the rear wall, etc. of the cabinet. The setting position of the opening 71 can be flexibly adjusted according to actual use requirements. It should be noted that openings 71 can also be provided on each cabinet wall 7 of the cabinet. When not in use, the openings 71 can all be in a blocked state. When the device is placed in a corresponding corner, the opening 71 to be opened can be selected according to the actual placement orientation, and then the corresponding opening 71 can be opened and connected to the corresponding air inlet 11 of the drying channel 1.
[0065] In some embodiments, both the first cylinder 3 and the drying channel 1 are located inside the cabinet. The drying channel 1 is connected to the first cylinder 3, and at least part of the drying channel 1 is located between the first cylinder 3 and the cabinet wall 7 provided with the opening 71.
[0066] For example, as Figure 3 shown, the drying channel 1 can be the first drying channel 51 of the first drying system 5 described above. The first cylinder 3, the first drying channel 51, and the right side cabinet wall 7 of the cabinet can be arranged in sequence along the left - right direction. Among them, the first drying channel 51 can be located between the first cylinder 3 and the cabinet wall 7. The right side surface of the first drying channel 51 can be in contact with the cabinet wall 7, and the second air outlet 53 on the first drying channel 51 can be directly docked and communicated with the opening 71. In some other embodiments, the second air outlet 53 on the first drying channel 51 can also be hermetically docked and communicated with the opening 71 through an additional pipeline.
[0067] In some embodiments, the drying channel 1 includes a protruding section 54 protruding above the first cylinder 3. A plurality of air inlets 11 are all provided on the protruding section 54, and at least two air inlets 11 are arranged opposite to each other in the interval direction between the first cylinder 3 and the cabinet wall 7 provided with the opening 71.
[0068] For example, as Figure 3As shown, the drying tunnel 1 can be the first drying tunnel 51 mentioned above. The first drying tunnel 51 can generally be arranged between the first cylinder 3 and the box wall 7. And a part of the first drying tunnel 51 can protrude upward from the first cylinder 3 to form a protruding section 54. The protruding section 54 can also extend along the front-rear direction, and the protruding section 54 is generally located within the included angle of the top side formed by the first cylinder 3 and the box wall 7.
[0069] Two air inlets 11 can be provided on the first drying tunnel 51. The two air inlets 11 are respectively the first air inlet 52 and the second air inlet 53. Among them, the first air inlet 52 can be arranged on the left side wall of the first drying tunnel 51, and the second air inlet 53 can be arranged on the right side wall of the first drying tunnel 51.
[0070] In some embodiments, the width dimension of the box body is 550 mm to 650 mm. For example, as Figure 4 shown, the width dimension of the box body can be dimension M. Dimension M can be 550 mm, 560 mm, 570 mm, 580 mm, 590 mm, 600 mm, 610 mm, 620 mm, 630 mm, 640 mm, 650 mm, etc.
[0071] In some embodiments, the height dimension of the box body is 800 mm to 900 mm. For example, as Figure 3 shown, the height dimension of the box body can be dimension H. Dimension H can be 800 mm, 810 mm, 820 mm, 830 mm, 840 mm, 850 mm, 860 mm, 870 mm, 880 mm, 890 mm, 900 mm, etc.
[0072] In some embodiments, the fan 2 is a double-suction fan 2. Specifically, the double-suction fan 2 can specifically be a double-suction centrifugal fan 2. The double-suction fan 2 includes two impellers. When in use, air flow such as air can flow into the double-suction impeller from the air inlets 11 on both sides of the fan 2. Since the bearing loads on both sides of the fan 2 are the same, the fan 2 has the advantages of small impeller axial force, large flow coefficient, high operation stability and reliability, etc. Thus, it can further play the role of reducing vibration and noise, and also meets the use requirements of supplying a large amount of air volume and air pressure.
