DETAILED DESCRIPTION

[0031] In order to make the purpose and implementation method of the present application clearer, the exemplary implementation method of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0032] It should be noted that the brief description of terms in this application is only for the convenience of understanding the embodiments described below, and is not intended to limit the embodiments of this application. Unless otherwise specified, these terms should be understood according to their common and usual meanings.

[0033] The terms "first", "second", "third", etc. in the specification and claims of this application and the above drawings are used to distinguish similar or similar objects or entities, and do not necessarily mean to limit a specific order or sequence, unless otherwise noted. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances.

[0034] The terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover but not exclude inclusion, for example, a product or device comprising a list of components is not necessarily limited to all the components expressly listed but may include other components not expressly listed or inherent to such product or device.

[0035] As the washing machine is used continuously, clothing lint will accumulate in the drying duct, at the fan impeller, at the air outlet of the outer drum, and at the air inlet temperature probe. When enough lint accumulates, it will clog the air duct and impeller, affecting the operation of the fan and the drying efficiency of the dryer.

[0036] In the related art, a connection piece is provided between the air inlet and the air outlet, and a nozzle is provided in the connection piece, and the nozzle is used to spray water to flush the air outlet to prevent the accumulation of hair debris. However, since the air outlet and the air inlet are not in the same position, the nozzle has a single function and can only flush a single position, and it is impossible to flush the hair debris accumulated in different positions. In order to solve this problem, the present application provides a drum washing machine.

[0037] For ease of understanding, the direction of the drum washing machine facing the user is the front direction, and the direction facing away from the user is the rear direction.

[0038] Figure 1 A schematic diagram of the internal structure of a drum washing machine according to some embodiments is shown.

[0039] See also Figure 1 A drum washing machine comprises a housing, an outer drum 1, a drying air duct 2 and a flushing part 3.

[0040] Among them, the box body is the external overall structure of the drum washing machine. The box body is a hollow structure. The outer periphery of the box body is rectangular and has an internal space, in which other component structures of the drum washing machine can be arranged, such as circuit structure, air duct structure, drive mechanism and drainage structure.

[0041] The outer cylinder 1 is arranged in the box body and is supported in a fixed manner inside the box body. The inner cylinder is arranged inside the outer cylinder 1, and the inner cylinder is rotatably arranged in the outer cylinder 1. A rotating shaft is arranged on the axis of the outer cylinder 1, and the rotating shaft passes through the rear wall of the outer cylinder 1 and is connected to the inner cylinder.

[0042] The front side of the box body is open, and a door body is provided at the opening, and the door body is used to close the opening. One end of the outer drum 1 is opened to form a clothing input port 11, and the clothing input port 11 corresponds to the front side opening of the box body, so that after the door body is opened, clothing can be put into the inner drum through the clothing input port 11. A door seal is also provided on the clothing input port 11 of the outer drum 1 to play a sealing role when the door body is closed. The door seal also prevents foreign objects from entering between the outer drum 1 and the inner drum.

[0043] In this embodiment, the drying duct 2 is arranged on the outer wall of the outer drum 1, a dryer and a fan 22 are arranged in the drying duct 2, an air inlet 21 and an air outlet are arranged at both ends of the drying duct 2, an air outlet 13 is arranged on the outer wall of the outer drum 1, the air outlet is connected to the clothing inlet 11, and the air inlet 21 is connected to the air outlet 13, so that the drying duct 2 and the outer drum 1 form an air circulation channel. The dryer is used to heat and dry the air in the drying duct 2, so that the fan 22 is arranged at one end close to the air inlet 21, and the impeller of the fan 22 is located at the air inlet 21 to guide the air from the outer drum 1 to the drying duct 2 and send it into the dryer, so as to speed up the air circulation, and continuously pump the humid air in the outer drum 1 to the dryer for heating to dry the clothes.

[0044] It is conceivable that the dryer may include an evaporator and a condenser arranged in sequence in the drying air duct 2, and the moist cold air flows through the evaporator and the condenser successively to become dry hot air, and then flows back to the outer drum 1 to dry the clothes.

[0045] Figure 2 A front view of an outer drum of a drum washing machine according to some embodiments is shown; Figure 3 Shows Figure 2 Sectional view in the AA direction; Figure 4 Shows Figure 3 A partial enlarged view of point B in the middle.

[0046] Among them, continue to see Figures 2 to 4 The inner bottom of the outer cylinder 1 protrudes outward to form an air collecting groove 12, and one end of the air collecting groove 12 penetrates the outer peripheral wall of the outer cylinder 1 to form an air outlet 13. The air in the outer cylinder 1 is firstly enriched by the air collecting groove 12, and then enters the drying air duct 2 through the air outlet 13. The air collecting groove 12 is provided to concentrate the air, slow down the flow rate of the air, reduce the noise, and make the air flow smoothly to the air outlet 13.

[0047] It can be understood that in order to prevent impurities in the clothes from being sucked into the drying duct 2, a filter element 14 is provided at the inner bottom of the outer drum 1 in front of the air collecting groove 12, and filter holes are opened on the filter element 14. The air in the outer drum 1 enters the air collecting groove 12 after passing through the filter holes, and then enters the drying duct 2 through the air outlet 13.

[0048] In some embodiments, the drying duct 2 includes an upper duct casing and a lower duct casing, which are fixedly connected by screws, and the enclosed space between the two forms the drying duct 2, wherein the lower duct casing is fixed on the outer peripheral wall of the outer cylinder 1, and the air inlet 21 is opened on the lower duct casing and faces the outer peripheral wall of the outer cylinder 1.

[0049] It is understandable that in order to maximize the drying effect, the drying duct 2 can be made longer and the air circulation path can be made longer. The air outlet 13 is set at the edge of the outer wall of the outer cylinder 1, and the air inlet 21 of the drying duct 2 is close to the rear side of the outer cylinder 1.

[0050] In this embodiment, the flushing member 3 includes a flushing portion and a side enclosure 31 arranged around the flushing portion, so that the flushing member 3 forms a cylindrical structure with one end open, and the side enclosure 31 is sealed and connected to the outer peripheral wall of the outer cylinder 1. The flushing portion, the side enclosure 31 and the outer peripheral wall of the outer cylinder 1 enclose a flow passage, and the air outlet 13 is located in the flow passage, and the air coming out of the air outlet 13 first enters the flow passage. The side of the flushing portion facing away from the outer peripheral wall of the outer cylinder 1 is sealed and connected to one end of the drying air passage 2 provided with an air inlet 21, and the flushing portion is provided with a ventilation hole 35, and the ventilation hole 35 is arranged corresponding to the air inlet 21 to connect the flow passage and the drying air passage 2. After passing through the flow passage and the ventilation hole 35, the air is sucked into the drying air passage 2 by the fan 22. The side enclosure 31 is provided to use the outer peripheral wall of the outer cylinder 1 for sealing, simplifying the sealing structure of the flushing member 3 and preventing air leakage. At the same time, the side enclosure 31 is in direct contact with the outer cylinder 1, and the support provided by the outer cylinder 1 is greater, which can better support and fix the drying air passage 2.

[0051] In some embodiments, a flushing cavity 34 surrounding the ventilation hole 35 is further provided on the flushing portion, and the flushing cavity 34 is connected to a water source. A first flushing hole 341 and a second flushing hole 342 connected to the flushing cavity 34 are provided on the flushing portion, and the first flushing hole 341 and the second flushing hole 342 are respectively opened toward the air inlet 21 and the air outlet 13. After water enters the flushing cavity 34, the impeller and the air collecting tank 12 of the fan 22 are flushed, so that the accumulated hair debris in the air inlet 21, the fan 22, the air outlet 13 and the air collecting tank 12 can be flushed. By utilizing the formed flushing cavity 34, the flushing range is expanded, and the flushing holes can be led out in various directions, so as to flush multiple parts, thereby solving the problem of single flushing part in the prior art and reducing hair debris accumulation.

[0052] In some embodiments, a limiting groove is recessed on the outer wall of the outer cylinder 1, and the bottom of the side enclosure 31 is clamped in the limiting groove, thereby fixing the side enclosure 31 and the flushing component 3, and sealing the flow duct. Some positions can also be fastened to the outer wall of the outer cylinder 1 by screws.

[0053] Figure 5 The structure of the washing part of the drum washing machine according to some embodiments is shown as an example Figure 1 ; Figure 6 The structure of the washing part of the drum washing machine according to some embodiments is shown as an example Figure 2 ; Figure 7 The structure of the washing part of the drum washing machine according to some embodiments is shown as an example Figure 3 ; Figure 8 Shows Figure 7 Cross-sectional view along CC direction.

[0054] In some embodiments, see Figures 5 to 8The flushing part includes a connector 32 and a flushing tray 33. The side enclosure 31 is connected to the edge of the connector 32. The side enclosure 31 and the connector 32 can be formed as one piece, so that the connector 32 and the side enclosure 31 form a cylindrical structure with one end open. The flushing tray 33 is sealed in the side enclosure 31 and has a certain distance from the connector 32. The space between the two defines a flushing cavity 34, so that the flushing cavity 34 is a closed space that can store water without leaking. The flushing cavity 34 is formed by enclosing two parts, which is convenient for each to be formed separately and then combined to form the flushing cavity 34. Of course, in some embodiments, the flushing cavity 34 can be a cavity opened inside the flushing part itself, and the connector 32 and the flushing tray 33 are formed as one piece. Among them, the drying air duct 2 is provided with an air inlet 21 at one end which is sealed and connected to the connecting piece 32, and the drying air duct 2 and the outer peripheral wall of the outer cylinder 1 are connected by the connecting piece 32, and the flushing plate 33 faces the outer peripheral wall of the outer cylinder 1. The first flushing hole 341 can be opened on the wall of the ventilation hole 35 to enable flushing toward the air inlet 21, and the second flushing hole 342 can be opened on the flushing plate 33 to enable flushing toward the air outlet 13.

[0055] In some embodiments, a water inlet 345 is provided on the connecting member 32 , the water inlet 345 is communicated with the flushing chamber 34 , and the water inlet 345 is connected to a water inlet valve through a rubber tube, and the water inlet valve controls the water source to enter the flushing chamber 34 .

[0056] The connection member 32 and the flushing plate 33 penetrate at the position corresponding to the air inlet 21 to form a ventilation hole 35. Specifically, the connection member 32 penetrates at the position corresponding to the air inlet 21 to form a first through hole 36, and the flushing plate 33 penetrates at the position corresponding to the air inlet 21 to form a second through hole 37, the second through hole 37 is sleeved outside the first through hole 36, the aperture of the second through hole 37 is larger than the first through hole 36, and the two are coaxially arranged. The hole wall of the second through hole 37 protrudes in the direction away from the outer peripheral wall of the outer cylinder 1 to form a first annular convex rib 331, and the flushing plate 33 also protrudes in the direction away from the outer peripheral wall of the outer cylinder 1 to form a second annular convex rib 332. The inner diameter of the second annular convex rib 332 is larger than the inner diameter of the first annular convex rib 331. The second annular convex rib 332 is sleeved outside the first annular convex rib 331. The two are in close contact with the connecting member 32 so that there is a distance between the flushing plate 33 and the connecting member 32 to form a flushing cavity 34. In this case, the first annular convex rib 331, the second annular convex rib 332, the connecting member 32 and the flushing plate 33 enclose the flushing cavity 34.

[0057] It is understandable that after the second through hole 37 is sleeved outside the first through hole 36, the first through hole 36 constitutes the ventilation hole 35, and the air flows from the flow passage to the air inlet 21 through the first through hole 36. When the connecting piece 32 is connected to the drying air duct 2, one end of the drying air duct 2 provided with the air inlet 21 is supported on the connecting piece 32, and the inner wall of the air inlet 21 protrudes toward the outer peripheral wall of the outer cylinder 1 to form a convex edge, which is inserted into the first through hole 36, so as to achieve the connection between the air inlet 21 and the ventilation hole 35, and a sealing ring can also be provided between the two to improve the sealing performance and prevent air leakage.

[0058] In some embodiments, the hole wall of the first through hole 36 protrudes toward the outer peripheral wall of the outer cylinder 1 to form a third annular convex rib 321, and the connecting piece 32 also protrudes toward the outer peripheral wall of the outer cylinder 1 to form a fourth annular convex rib 322 and a fifth annular convex rib 323. The inner diameter of the third annular convex rib 321 is smaller than the inner diameter of the fourth annular convex rib 322. The fourth annular convex rib 322 is sleeved outside the third annular convex rib 321, and a first sealing groove 324 corresponding to the direction of the first annular convex rib 331 is formed therebetween. The first annular convex rib 331 is closely connected to the first sealing groove 324, so that the first annular convex rib 331 is in compression contact with the first sealing groove 324, and the two are pressed against each other, so that good sealing is achieved while clamping the first annular convex rib 331 to avoid air leakage from the first sealing groove 324.

[0059] Correspondingly, the inner diameter of the fifth annular convex rib 323 is larger than that of the fourth annular convex rib 322. The fifth annular convex rib 323 is sleeved outside the fourth annular convex rib 322 and spaced from the side circumference 31. A second sealing groove 325 corresponding to the direction of the second annular convex rib 332 is formed between the two. The second annular convex rib 332 is closely connected in the second sealing groove 325, so that the second annular convex rib 332 and the second sealing groove 325 are pressed and contacted. The two are pressed against each other, and good sealing is achieved while clamping the second annular convex rib 332, thereby preventing air leakage from the second sealing groove 325. The first sealing groove 324 and the second sealing groove 325 are formed by convexly arranging the third annular convex rib 321, the fourth annular convex rib 322 and the fifth annular convex rib 323, so that the distance between the connecting member 32 and the flushing tray 33 can be larger, the volume of the flushing cavity 34 can be larger, more water sources can be introduced, and the flushing effect is better.

[0060] In some embodiments, the first sealing groove 324 and the second sealing groove 325 may also be formed by partially recessing the connecting member 32 itself.

[0061] In some embodiments, the second annular rib 332 extends along the outer edge of the flushing plate 33, so that the coverage of the flushing cavity 34 can be maximized, and the flushing holes can flush more positions. At the same time, the space between the side enclosure 31 and the fifth annular rib 323 forms a second sealing groove 325, which also maximizes the coverage of the flushing cavity 34, and the flushing plate 33 can be clamped in the side enclosure 31, which is convenient for installing the flushing plate 33.

[0062] In some embodiments, screw columns are provided at corresponding positions of the flushing tray 33 and the connecting member 32, the two screw columns are opposite to each other, and the two are screwed together by screws to form a screw group. Multiple screw groups can be arranged between the flushing tray 33 and the connecting member 32 to fix the two and facilitate installation and disassembly.

[0063] In some embodiments, a portion of the third annular rib 321 protrudes toward the center of the first through hole 36 to form a boss 326, and a first flushing hole 341 is provided on a side of the boss 326 facing the air inlet 21, so that the first flushing hole 341 can spray and flush from the first through hole 36 directly toward the air inlet 21, and the flushing position is better, so that more flushing water can reach the air inlet 21 and the impeller of the fan 22, thereby improving the flushing effect on the impeller and hair debris in the drying duct 2.

[0064] Among them, the fourth annular convex rib 322 and the third annular convex rib 321 have corresponding directions, so that the fourth annular convex rib 322 also convexes toward the center direction of the first through hole 36 at the position corresponding to the third annular convex rib 321 protruding to form the boss 326, so that the width of each position of the first sealing groove 324 can be equal, so that the first annular convex rib 331 is closely connected to the first sealing groove 324. The first flushing hole 341 is located outside the fourth annular convex rib 322, so that the first flushing hole 341 can be connected with the flushing cavity 34. It can be understood that the inner side of the fourth annular convex rib 322 refers to the side facing the center of the first through hole 36, and the outer side refers to the side facing the side circumference 31.

[0065] Fig. 9 A schematic diagram of the structure of a connecting member of a drum washing machine according to some embodiments is exemplarily shown; Fig.10 A schematic structural diagram of a washing tray of a drum washing machine according to some embodiments is exemplarily shown.

[0066] In some embodiments, see Fig. 9 and Fig.10The first annular rib 331 partially protrudes toward the center of the second through hole 37 to form a sealing portion 333 covering the boss 326. The sealing portion 333 is arranged in a one-to-one correspondence with the boss 326, so that after the first annular rib 331 is inserted into the first sealing groove 324 at the corresponding position of the boss 326, the sealing portion 333 can block the corresponding boss 326 to make it sealed. Among them, the side of the sealing portion 333 is provided with a third flushing hole 343 connected to the flushing cavity 34. The third flushing hole 343 is opened toward the side enclosure 31 to flush the side enclosure 31 and the flushing plate 33, thereby cleaning the hair debris accumulated in both.

[0067] Among them, the sealing part 333 is recessed toward the outer wall of the outer tube 1 to form a sink 334, the edge of the sink 334 is connected to the first annular rib 331, the sink 334 just corresponds to the boss 326 to cover the boss 326, and the side of the sink 334 is provided with the third flushing hole 343, so that flushing can be sprayed toward the side enclosure 31 and the flushing plate 33.

[0068] In some embodiments, a plurality of bosses 326 are provided at circumferential intervals along the first through hole 36, and each boss 326 is provided with the first flushing hole 341 on the side facing the air inlet 21, so that the air inlet 21 and the impeller of the fan 22 can be flushed in all directions, thereby improving the flushing efficiency and quality. The number of bosses 326 is determined according to actual conditions. In the present embodiment, three bosses 326 are provided at circumferential intervals along the first through hole 36. Of course, there may also be two, four, etc.

[0069] It is understandable that the number and position of the sealing parts 333 correspond to the boss 326. In this embodiment, three sealing parts 333 are arranged along the circumference of the second through hole 37. At the same time, in order to expand the flushing range of the side enclosure 31 and the flushing plate 33, the two opposite sides of the sealing part 333 are provided with third flushing holes 343. The plurality of sealing parts 333 are provided with a plurality of third flushing holes 343, so as to fully flush the side enclosure 31 and the flushing plate 33 and prevent hair scraps from accumulating thereon.

[0070] In some embodiments, in order to enhance the connection stability between the connector 32 and the flushing tray 33 and improve the sealing between the two, a buckle position 335 is provided at one end of the sealing portion 333 close to the center of the second through hole 37, and a buckle 327 is provided at one end of the boss 326 close to the center of the first through hole 36, so that the buckle 327 is buckled into the buckle position 335, and is used to connect the flushing tray 33 and the connector 32. At the beginning of the installation, after the flushing tray 33 and the connector 32 are aligned, they are first connected by the buckle 327 and finally fixed by the screw column, thereby improving the connection reliability. The buckle 327 connection also makes the connection between the sealing portion 333 and the boss 326 tighter, which can enhance the sealing here.

[0071] In some embodiments, one end of the sealing portion 333 near the center of the second through hole 37 extends toward the center of the second through hole 37 and then extends toward the air inlet 21 to form an L-shaped elastic arm. An opening is provided on the L-shaped elastic arm, and the opening constitutes the buckle position 335. When the flushing tray 33 is installed, after the flushing tray 33 is abutted against the connecting member 32, the buckle 327 is snapped into the buckle position 335, so that the two are buckled together.

[0072] In some embodiments, a mounting hole 311 is provided on the side enclosure 31, and a temperature sensor 4 is installed on the mounting hole 311. The detection end of the temperature sensor 4 extends into the side enclosure 31, so as to detect the temperature at the air inlet 21. When it detects that the temperature reaches a threshold, it indicates that the air coming out of the outer drum 1 is hot air, and the drying is completed, thereby ending the operation of the dryer. Among them, a fourth flushing hole 344 connected to the flushing cavity 34 is provided on the flushing plate 33. The fourth flushing hole 344 is adjacent to the temperature sensor 4 and is arranged toward the temperature sensor 4, so that after long-term use, the temperature sensor 4 is flushed to avoid the accumulation of hair debris on it, which affects its detection accuracy.

[0073] In some embodiments, at least a portion of the flushing plate 33 is directly opposite to the air outlet 13, and a plurality of second flushing holes 342 are provided and are spaced apart on the portion of the flushing plate 33 directly opposite to the air outlet 13, so as to directly flush the air outlet 13, the air collecting tank 12, and the filter 14. The emission angles of the plurality of second flushing holes 342 may be different, and the intervals between the second flushing holes 342 at different positions are relatively large, so as to be able to flush the air collecting tanks 12 at different positions.

[0074] In summary, in the present embodiment, by setting up the flushing cavity 34 and utilizing the flushing cavity 34 to expand the setting area of ​​the flushing hole, flushing holes facing different objects can be set as needed, such as the first flushing hole 341, the second flushing hole 342, the third flushing hole 343 and the fourth flushing hole 344 in the present embodiment, which can flush different objects at different positions, solve the problem of single flushing position in the prior art, and improve the dander cleaning capacity at each position, thereby avoiding dander accumulation and improving drying efficiency.
