Description

Technical Field

[0001] The present invention belongs to the field of washing machines, and in particular relates to a washing machine with a drying function. Background Art

[0002] Currently, clothes drying devices with drying functions are categorized into dedicated drying devices and dual-purpose drying devices. Dedicated drying devices only have a drying function, while dual-purpose drying devices also have a washing function. Based on their structure and form, they are further categorized into drum-type devices and cabinet-type devices. Drum-type devices utilize a rotating drum to dry clothes by turning them over, while cabinet-type devices hang clothes for drying.

[0003] Generally speaking, existing drying and washing machines include an outer tub for storing wash water. A rotatable drum containing laundry is located within the outer tub. The drum is connected to a rotating shaft, and a motor is used to rotate the shaft. The shaft is rotatably supported by a bearing seat provided on the rear wall of the outer tub. The outer tub is connected to a suspension, which acts to dampen vibrations of the drum and outer tub.

[0004] For the drying function, a drying duct and a condensing duct are included. The drying duct is located on the upper part of the outer barrel, and a hot air heater and a fan are installed inside. One end of the condensing duct is connected to the outer barrel, and the other end is connected to the drying duct. In order to condense the moisture contained in the humid air, cooling water is supplied to the inside of the condensing duct. The humid air flows through the condensing duct, contacts the cooling water, and is condensed before flowing into the drying duct. In this way, the hot air that returns to the drying duct is reheated by the hot air heater and supplied to the washing drum again. Summary of the Invention

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0058] Example 1

[0059] A washing machine with a drying function, such as Figures 1-13 As shown, the washing machine includes a casing (not shown in the figure), an outer drum 1 is provided in the casing, and the outer drum 1 is supported in the casing in a fixed manner; a drum 2 is provided inside the outer drum 1, and the drum 2 is rotatably arranged in the outer drum 1; a rotating shaft is provided on the axis of the outer drum 1, and the rotating shaft passes through the rear of the outer drum 1 and is connected to the drum 2.

[0060] The housing is provided with an opening for inserting laundry. plate . The opening portion of the front plate is provided with a door body, and the door body is used to close the opening portion. The outer drum 1 includes a front outer drum 19 forming the front portion and a rear outer drum 10 forming the rear portion. The front outer drum 19 and the rear outer drum 10 are assembled using a coupling such as screws, and a space for accommodating the drum 2 is formed inside the front outer drum 19 and the rear outer drum 10. The end of the front outer drum 19 close to the front side is recorded as the front end portion 19, and the front end portion 13 of the front outer drum 19 is formed with an inlet 191 so that laundry can be put in; the inlet 191 is connected to the door body. The front side of the drum 2 is provided with an inner drum opening, and the inner drum opening corresponds to the inlet 191; the drum 2 is provided with a water flow hole 22 to connect the drum 2 and the outer drum 1. The inner circumferential surface of the inlet 191 of the outer drum 1 is formed with a rim portion protruding toward the front of the outer drum 1. The rim portion is connected to the exhaust port 411 of the drying air duct 41. In addition, the rim has a gasket for maintaining airtightness between the rim and the opening on the housing front plate. The gasket also prevents foreign matter from entering between the outer cylinder 1 and the drum 2.

[0061] In order to realize the drying function, the washing machine of the present invention is provided with an air flow part 4, which is fixedly arranged outside the outer drum 1. The air flow part 4 can heat the air and form an air circulation with the inner part of the outer drum 1. Figure 1-Figure 3As shown, the air flow section 4 includes an air collecting channel 17 and a drying channel 41, which is connected to the air collecting channel 17. The inner wall surface of the rear wall of the outer cylinder 1 is designated as the inner rear wall 11, and the circumferential side wall of the outer cylinder 1 is designated as the outer peripheral wall 12. The inner rear wall 11 of the outer cylinder 1 is provided with an air inlet 171, and the outer peripheral wall 12 of the outer cylinder 1 is provided with an air outlet 172. The air inlet 171 and the air outlet 172 are connected to form the air collecting channel 17. One end of the drying channel 41 is connected to the air outlet 172 of the air collecting channel 17; the other end is an exhaust port 411, which is connected to the interior of the outer cylinder 1. Air passing through the air collecting channel 17 enters the drying channel 41 through the air outlet 172, is heated in the drying channel 41, and is then supplied to the interior of the outer cylinder 1 through the exhaust port 411.

[0062] The inner rear wall 11 of the rear outer tube 10 is provided with a recessed portion 16. This recessed portion 16 is recessed rearward, forming an air inlet 171 for the air collection channel 17 on the inner rear wall 11 of the rear outer tube 10, and an air outlet 172 for the air collection channel 17 on the outer peripheral wall 12 of the rear outer tube 10. Air within the outer tube 1 is first concentrated by the air collection channel 17 before entering the drying duct 41 for drying under the action of the air flow unit 4. The provision of the recessed portion 16 not only facilitates air concentration but also helps moderate the air flow rate and reduce noise, achieving quiet drying and improving the user experience.

[0063] The outer circumferential wall 12 of the outer tub 1 is provided with a fixing protrusion 18, which is provided with a threaded hole. The edge of the drying duct 41 is provided with a plurality of first fixing plates 412, each of which is provided with an opening. The first fixing plates 412 on the drying duct 41 correspond to the fixing protrusions 18 provided on the outer circumferential wall 12 of the outer tub 1, and the openings on the first fixing plates 412 correspond to the threaded holes on the fixing protrusions 18, and screws are used to secure the drying duct 41 to the outer circumferential wall 12 of the outer tub 1. The fixing protrusion 18 includes a second fixing post 181 and a protrusion 182. The protrusion 182 is provided on the outer circumferential wall 12 of the outer tub 1, near the rear wall. The second fixing post 181 is arranged around the edge of the drying duct 41. The drying air duct 41 is provided with a first reinforcing plate 413 , which connects the first fixing plate 412 and the drying air duct 41 to effectively strengthen the connection strength between the first fixing plate 412 and the drying air duct 41 .

[0064] The drying duct 41 is located in the upper portion 14 of the outer drum 1. When the washing machine is performing a drying cycle, the air flow unit 4 circulates and heats the air inside the outer drum 1. Specifically, the drying duct 41 directs the airflow collected by the air collecting channel 17 out of the outer drum 1, heats the airflow, and then flows it back into the outer drum 1 to dry the clothes.

[0065] The drying duct 41 is fixed to the upper part 14 of the outer drum 1 and is offset from the upper part by 8° to 25°. In this embodiment, the drying duct 41 is fixed to the upper part 14 of the outer drum 1 and is located at a position inclined to the right at a certain angle. The above arrangement enables the drying duct 41 to act as a counterweight to reduce the cost of the product. At the same time, it balances the weight distribution of the washing machine to improve the stability of the washing machine. Furthermore, fixing the drying duct 41 to the casing requires a rubber tube to connect the outer drum 1 and the drying duct 41. The movement of the rubber tube causes unstable changes in the air pressure in the duct and the drum. Because the outer drum 1 is a moving part, the drying duct 41 is directly fixed to the outer drum 1 in the present invention. This avoids the use of a rubber tube to connect the outer drum 1 and the drying duct 41, reducing the cost of the product and avoiding the risk of the outer drum 1 vibration being transmitted to the casing, causing the entire washing machine to shift. In addition, in this embodiment, the drying duct 41 is configured to be linear. The linear duct design can minimize the resistance of the duct, reduce the requirements for fan performance, and improve drying efficiency.

[0066] The air flow unit 4 includes an upper duct housing 44 and a lower duct housing 45, which are connected by screws to form a drying duct 41. A fan 42 is installed within the drying duct 41. The fan 42 is located near the air outlet 172 of the air collecting duct 17 and uses the air collecting duct 17 to collect and move air. A heater 43 is installed within the drying duct 41, located in an area near the front of the fan 42. The heater 43 heats the air moved by the fan 42. The heated air is then introduced into the outer drum 1 through the exhaust port 411, thereby drying the clothes in the drum 2.

[0067] The drying air duct 41 and the air collecting channel 17 can be connected directly or through an adapter 5, one end of the adapter 5 is sealed with the air outlet 172 of the air collecting channel 17, and the other end is fixedly connected to the drying air duct 41; the provision of the adapter 5 can effectively reduce the difficulty of connecting the drying air duct 41 and the air collecting channel 17, facilitate installation, and reduce the difficulty of processing the drying air duct 41.

[0068] The adapter 5 includes a top wall 51 and a side wall arranged around the top wall 51; the side wall of the adapter 5 located on the front side of the washing machine is recorded as the front side wall 52; a through hole 511 is provided on the top wall 51 of the adapter 5, and the edge of the side wall arranged around the top wall 51 on the adapter 5 forms a connecting port 53; the outer peripheral wall 12 of the outer drum 1 is provided with a plurality of first fixing columns 173 on the periphery of the air outlet 172, and the first fixing columns 173 are provided with fixing holes 1731; the distribution path of the plurality of first fixing columns 173 is consistent with the shape of the connecting port 53 on the adapter 5.

[0069] A second fixing plate 531 is provided on the edge of the connection port 53 on the adapter 5, and a connection hole 5311 is provided on the second fixing plate 531; the second fixing plate 531 corresponds to the first fixing column 173 on the outer peripheral wall 12 of the outer tube 1, and the connection hole 5311 on the second fixing plate 531 corresponds to the fixing hole 1731 on the first fixing column 173; screws are installed in the connection hole 5311 and the fixing hole 1731 to fix the adapter 5 to the outer peripheral wall 12 of the outer tube 1; the connection port 53 on the adapter 5 surrounds the air outlet 172 of the gas collecting channel 17. The through hole 511 on the adapter 5 corresponds to the air duct opening of the drying air duct 41, and the top wall 51 of the adapter 5 is fixedly connected to the end of the drying air duct 41; a first sealing ring 512 is provided at the connection between the end of the drying air duct 41 and the top wall 51 of the adapter 5; a second sealing ring 500 is provided at the connection between the connecting port 53 on the adapter 5 and the outer peripheral wall 12 of the outer cylinder 1; the first sealing ring 512 and the second sealing ring 500 are provided to effectively seal the connection to avoid air leakage, thereby improving the drying efficiency.

[0070] Under the action of the fan 42 in the air flow part 4, the air passing through the clothes in the washing machine is guided to the air collecting channel 17. The air enters from the air inlet 171 of the air collecting channel 17, enters the adapter 5 through the air outlet 172, and then enters the drying duct 41 through the through hole 511 on the top wall 51 of the adapter 5. After being heated by the heater 43 in the drying duct 41, the air enters the outer drum 1 through the exhaust port 411 to dry the clothes, thus forming a cycle.

[0071] A condensate supply device 7 is located on the upper inner portion of the housing. This device includes a condensate line 721, which communicates with the interior of the outer tub 1 to supply condensate thereto. One end of the condensate line 721 is connected to a water supply valve, and the other end is connected to the outer tub 1. The water supply valve controls the flow of condensate. Furthermore, a drain unit (not shown) consisting of a drain pipe and a drain pump is located on the lower inner portion of the housing. This drain unit discharges wash water used in washing and rinsing, as well as condensate from the drying process, to the exterior.

[0072] The upper portion 14 of the rear outer tube 10 is provided with a condensate inlet column 15, located near the rear wall of the rear outer tube 10. A condensate inlet channel 151 is provided on the condensate inlet column 15, connecting the interior and exterior of the outer tube 1 and directing condensate toward the inner rear wall 11 of the rear outer tube 10. The condensate pipe 721 of the condensate supply device 7 is connected to the condensate inlet column 15 of the upper portion 14 of the rear outer tube 10, so as to supply condensate through the condensate inlet channel 151 and into the inner rear wall 11 of the rear outer tube 10.

[0073] The condensate inlet column 15 is located at the center of the upper rear portion of the outer tube 1. The center of the upper rear portion of the outer tube 1 is the highest point of the entire outer tube 1. This arrangement maximizes the length of the condensate flow path. In addition, the condensate inlet column 15 is integrally formed with the outer tube 1.

[0074] A guide rib 8 is provided on the inner rear wall 11 of the rear outer tube 10 below the condensate inlet channel 151. The guide rib 8 extends downward from top to bottom and is curved. The guide rib 8 is divided into two left and right parts, with the vertical centerline of the rear wall of the outer tube 1 as the boundary, to maximize the residence time of the condensate on the inner rear wall 11 of the outer tube 1. The guide rib 8 diverts the condensate entering through the condensate inlet column 15, effectively preventing the condensate from concentrating and flowing along the minimum path after entering the outer tube 1 under the drive of its own gravity. The provision of the guide rib 8 provides the condensate with a larger contact area and surface tension, allowing the condensate to flow along the designed guide rib 8. The longer flow path forms a larger cooling surface, making the inner rear wall 11 of the outer tube 1, except for the air inlet 171 of the air collecting channel 17, the rest of the area, except for the air inlet 171 of the air collecting channel 17, a cooling wall surface for the wet air. The air inlet 171 of the air collecting channel 17 is set on the rear wall of the outer cylinder 1 instead of the side wall, so that the wet air must bypass the rear of the drum 2 and pass through the inner rear wall 11 of the outer cylinder 1 before entering the air flow part 4. This is more conducive to the heat exchange between the wet air and the inner rear wall 11 of the outer cylinder 1 to which the condensed water is applied, thereby drying the air in time to speed up the drying process and improve the drying efficiency.

[0075] The guide ribs 8 include a first guide rib 81, a second guide rib 82, and an anti-backflow rib 83. The anti-backflow rib 83 is located at the air inlet 171 of the air collection channel 17, on the side of the air inlet 171 close to the condensate inlet column 15. The anti-backflow rib 83 is arranged along the edge of the air inlet 171, and its shape is consistent with the shape of the air inlet 171. The anti-backflow rib 83 can effectively prevent condensate from being sucked into the air collection channel 17 during the drying process, causing the clothes to get wet again.

[0076] The first guide rib 81 includes a first support rib 811 and a second support rib 812 connected at one end and separated at the other end. The first support rib 811 and the second support rib 812 extend from the connection to the two sides of the radial line where the first support rib 811 and the second support rib 812 are connected on the bottom wall of the outer tube, that is, they are arranged in a "human" shape. In this embodiment, the first support rib 811 and the second support rib 812 are located on the mid-vertical line of the bottom wall of the outer tube from the connection. The first support rib 811 and the second support rib 812 extend to the left. The connection between the first support rib 811 and the second support rib 812 corresponds to the condensate inlet channel 151 on the condensate inlet column 15 provided on the outer peripheral wall of the outer tube 1, so as to first receive the condensate introduced by the condensate inlet channel 151 and divert it. The first support rib 811 and the second support rib 812 extend separately from the connection to both sides, and in this embodiment, extend to the left and right sides. The first support rib 811 is curved and extends to the lower part of the outer tube 1 to guide the condensed water to the drainage part; the second support rib 812 extends a part of its length toward the side close to the anti-backflow rib 83 and is separated from the anti-backflow rib 83.

[0077] The second guide rib 82 includes a third support rib 821, a fourth support rib 822 and a fifth support rib 823; the third support rib 821 and the fourth support rib 822 are connected at one end and separated at the other end, and the connection between the third support rib 821 and the fourth support rib 822 corresponds to the connection between the first support rib 811 and the second support rib 812; that is, the connection between the third support rib 821 and the fourth support rib 822, the connection between the first support rib 811 and the second support rib 812 and the outlet of the condensate inlet channel 151 are located on the same straight line; that is, the connection between the third support rib 821 and the fourth support rib 822 is located directly below the connection between the first support rib 811 and the second support rib 812. The third rib 821 is of the same shape as the first rib 811; the fourth rib 822 is of the same shape as the second rib 812; the third rib 821 and the fourth rib 822 extend downward for a distance; the fifth rib 823 is located below the fourth rib 822; preferably, in the vertical direction, the upper end of the fifth rib 823 at least partially overlaps with the lower end of the fourth rib 822. Optionally, the upper end of the fifth rib 823 also at least partially overlaps with the lower end of the second rib 812 in the vertical direction, so that the fifth rib 823 can receive condensed water guided by the second and fourth ribs 812, thereby extending the travel path of the condensed water guided by the second and fourth ribs 812, 822.

[0078] The fifth rib 823 avoids the air inlet 171 and extends downward to the lower portion of the outer drum 1 to direct condensed water to the drain. The segmented arrangement of the fifth rib 823, the second rib 812, and the fourth rib 822 effectively guides the flow of condensed water to the drain. It also avoids the air inlet 171 while extending the condensed water flow path. In horizontal projection, the lower end of the second guide rib 82 is located between the lower end of the fourth rib 822 and the condensed water inlet column 15. Water diverted by the second guide rib 82 is first received by the fourth rib 822 and then directed to the fifth rib 823. The condensed water supply device 7 supplies cold water to the inner rear wall 11 of the outer drum 1. When the washing machine performs a drying cycle, the cold water supplied by the condensed water supply device 7 flows along the inner surface of the outer drum 1. At the same time, the moist air from drying the laundry moves toward the air collecting channel 17, forming condensate on the condensation surface (inner rear wall) of the outer drum 1, where the cold water flows. Compared to existing structures that use condensation pipes to generate condensate, this structure, which utilizes the inner surface of the outer drum 1 to generate condensate, fully utilizes the existing structure of the washing machine, reducing the thickness increase caused by additional structure. Furthermore, because a larger area is used to generate condensate, the efficiency of condensate generation is improved.

[0079] The air in the outer drum 1 flows into the drying air duct 41 as the fan 42 is driven, and moves toward the heater 43. The heater 43 heats the air moved by the fan 42 to generate hot air. The air heated by the heater 43 is supplied to the inner part of the outer drum 1 through the exhaust port 411 to dry the laundry.

[0080] In this embodiment, a front temperature sensor 31 is provided at the front end of the outer drum 1 near the drying air duct 41 to detect the temperature of the heated air; a temperature limiter 32 is provided on the side wall of the drying air duct 41 corresponding to the position of the heater to limit the heating temperature; a rear temperature sensor 33 is provided on the adapter 5 to detect the air temperature in the air collecting channel 17; the setting of the above temperature sensors can effectively detect the temperature of each part to control the drying program, thereby improving the drying efficiency and drying effect, and reducing damage to clothes.

[0081] Example 2

[0082] This embodiment shares the same principles as the first embodiment, differing primarily in that a clean water inlet column 54 is provided on the top wall 51 of the adapter 5, and a clean water inlet channel 541 is provided on the clean water inlet column 54. One end of the clean water inlet column 54, located outside the adapter 5, serves as a pipe connection column 54. This connection column 54 and the sidewalls of the adapter 5 are located on either side of the top wall 51. A clean water pipeline 722 is connected to the clean water inlet column 54, which is connected to the condensed water supply device 7, which supplies condensed water to the clean water pipeline 722.

[0083] The clean water pipeline 722 is connected to the clean water inlet column 54 on the top wall 51 to introduce water from the condensation water supply device 7 into the recessed portion 16 forming the gas collecting channel 17. The water introduced into the gas collecting channel 17 through the clean water pipeline 722 flushes the gas collecting channel 17 and supplies condensation water to the rear wall of the outer cylinder.

[0084] The air collecting channel 17 is provided with a recessed portion 16 to connect the inner rear wall 11 of the outer tube 1 with the outer peripheral wall 12 of the outer tube 1. Although the recessed portion is conducive to air collection, it is also prone to the accumulation of fiber lint and the like, which can easily cause blockage of the air collecting channel 17. In this embodiment, a clean water inlet column 54 is provided on the adapter 5 to direct condensed water into the air collecting channel 17 to flush the air collecting channel 17 to remove the fiber lint and the like accumulated therein, thereby preventing the lint accumulation from causing blockage of the air collecting channel 17 and effectively ensuring the smooth flow of the air collecting channel 17. It also prevents the accumulation of lint from breeding bacteria.

[0085] Example 3

[0086] The difference between this embodiment and the second embodiment is that: Figure 13-16 As shown, the condensate supply device 7 in this embodiment includes a main line 72, with a three-way valve 73 at the other end of the main line 72; the other two joints of the three-way valve 73 are connected to the condensate line 721 and the clean water line 722 respectively. The condensate supply device 7 supplies condensate to the main line 72, and the condensate is discharged from the main line 72 and diverted to the condensate line 721 and the clean water line 722 through the three-way valve; it enters the outer tube through the condensate inlet channel 151 and the clean water inlet channel 541 in sequence; the condensate introduced by the condensate line 721 is directly sprayed onto the inner rear wall of the outer tube, cooling the inner rear wall of the outer tube over a large area; the condensate introduced by the clean water inlet channel 541 enters the air collection channel, and then flows from the air collection channel to the inner rear wall of the outer tube to cool the inner rear wall of the outer tube near the air inlet. In this embodiment, two condensate water channels are provided, which effectively increases the contact area between the condensate and the inner rear wall of the outer tube, thereby maximizing the condensation heat exchange effect. At the same time, the condensed water introduced through the clean water inlet channel 541 can also clean the gas collecting channel.

[0087] Example 4

[0088] The difference between this embodiment and the third embodiment is that: Figure 17 As shown, a water diverter plate 50 is provided within the gas collection channel 17. The water diverter plate 50 corresponds to the clean water inlet channel 541 of the clean water inlet column 54 and is located below the clean water inlet channel 541. The water diverter plate 50 diverts the condensed water entering through the clean water inlet channel 541, enabling multi-directional flushing of the gas collection channel and increasing the coverage area of ​​the condensed water. This not only enhances the condensation heat exchange effect, but also increases the flow rate and impact force of the water diverted by the diverter plate 50, effectively flushing the gas collection channel, achieving a better flushing effect and effectively improving flushing efficiency and effectiveness.

[0089] Example 5

[0090] The principle of this embodiment is the same as that of the first and second embodiments, and the main difference is that Figure 17 As shown, the air collection channel 17 is provided with a filter 9 at the air inlet 171 on the inner rear wall 11 of the outer cylinder. The filter 9 covers the air inlet 171 to filter the air entering the air collection channel 17. The filter 9 filters the air passing through the clothes to remove fiber and lint. At this time, the water flow introduced by the clean water inlet column 54 provided on the top wall 51 of the adapter 5 in the second embodiment can flush the filter 9, thereby removing fiber and lint filtered by the filter 9 by spraying clean water, preventing the filter 9 from clogging and causing blockage in the air inlet 171 of the air collection channel 17, and also preventing the accumulation of lint and the breeding of bacteria.

[0091] Example 6

[0092] The principle of this embodiment is the same as that of the third embodiment, and the main difference is that Figures 19-24As shown, the air collection channel 17 is provided with a debris filter nozzle 6, which corresponds to the air inlet 171 and is connected to the clean water inlet column 54. Because the drying air duct 41 is positioned at a certain angle above the outer cylinder 1, the debris filter nozzle 6 in this embodiment is vertically downward and corresponds to the air inlet 171, effectively utilizing the wash water's own gravity to move downward. The clean water inlet column 54 is located within the adapter 5 as a nozzle docking column 543. A first screw column 55 and a second screw column 56 are respectively provided on either side of the nozzle docking column 543. The first screw column 55, the nozzle docking column 543, and the second screw column 56 are collinear. A connecting plate 57 is provided between the first screw column 55, the nozzle docking column 543, and the second screw column 56 to connect the three together and effectively improve overall strength. A second reinforcing plate 58 is provided between the nozzle docking column 543 and the top wall 51. The second reinforcing plate 58 connects the nozzle docking column 543 to the top wall 51 as a whole, effectively strengthening the nozzle docking column 543.

[0093] The debris filter nozzle 6 includes a fixing portion 60 and a water spray rod 62. The fixing portion 60 is connected to the water spray rod 62 and connected to the nozzle docking post 543. The debris filter nozzle 6 is vertically downward. The water spray rod 62 is provided with multiple openings 63 for spraying clean water. The surface of the debris filter nozzle 6 that faces the air inlet 171 of the air collection channel 17 is designated as a first water spray surface 621. The fixing portion 60, distal from the water spray rod 62, is provided with a base plate 61. The base plate 61 has a first screw hole 611 on one side of the fixing portion 60 and a second screw hole 612 on the other side. The first screw hole 611 corresponds to the first screw post 55 on the adapter 5, and the second screw hole 612 corresponds to the second screw post 56 on the adapter 5. The base plate 61 is fixedly connected to the first and second screw posts 55, 56 via screws 59. In other words, the screws 59 securely connect the debris filter nozzle 6 to the nozzle docking post 543. The condensed water passing through the nozzle docking column 543 enters the water spraying rod 62 through the fixing portion 60 and is sprayed out from the opening 63 .

[0094] The opening 63 includes a first nozzle 631, which is located on the first water spray surface 621 of the debris filter nozzle 6. The first nozzle 631 includes a first spray hole 6311. Multiple first spray holes 6311 are located in the center of the first water spray surface 621 and are distributed along the axis of the water spray rod 62. The first spray holes 6311 spray water perpendicularly to the first water spray surface 621 to clean the area of ​​the filter screen 9 facing the first nozzle 6311. The first water spray surface 621 is provided with second spray holes 6312, which are located at the edge of the first water spray surface 621 and arranged in two rows on both sides of the first spray hole 6311. The second spray holes 6312 spray water at a preset angle to comprehensively clean the filter screen 9 with a wide cleaning radius. The end of the water spray rod 62, away from the fixed portion 60, is provided with a third spray hole 6313. This third spray hole 6313 is strip-shaped, effectively ensuring the water spray volume and spray range at the end of the debris filter nozzle 6. This arrangement effectively protects the cleaning range and ensures the water pressure, effectively cleaning the filter 9 and improving cleaning efficiency. In addition, the first spray holes 6311 and second spray holes 6312 in two adjacent rows are staggered relative to each other to reduce interference between the water sprays and ensure a good cleaning effect.

[0095] In addition, the number of nozzles can be increased or decreased in proportion to the area of ​​the filter screen 9. The number of nozzles, nozzle aperture, nozzle spacing, etc. can be changed in various forms, so the number of nozzles, nozzle aperture, nozzle spacing, etc. of the present invention are not limited.

[0096] Example 7

[0097] The principle of this embodiment is the same as that of the sixth embodiment, and the main difference is that Figure 25-28 As shown, a second nozzle 632 is provided at the top of the debris filter nozzle 6, facing away from the air inlet 171. This side of the debris filter nozzle 6, facing away from the air inlet 171, is designated the second water spray surface 622. The second nozzle 632 is provided on the second water spray surface 622 of the fixed portion 60. This second nozzle 632 faces the rear of the outer cylinder 1 to clean accumulated lint in the wind path deflection area of ​​the air collection channel 17. This second nozzle 632 is strip-shaped to maximize cleaning coverage of the rear wall of the outer cylinder 1. It extends downward along the circumferential surface of the fixed portion 60.

[0098] The fixed portion 60 is provided with a third nozzle 633 on the first water spraying surface 621. The third nozzle 633 faces the front sidewall 52 of the adapter 5 to clean lint and other debris accumulated in the adapter 5 during the drying process. The second nozzle 632 is strip-shaped to maximize cleaning of the front sidewall 52 of the adapter 5. The third nozzle 633 extends downward along the circumferential surface of the fixed portion 60.

[0099] The above-mentioned setting of the second nozzle 632 and the third nozzle 633 effectively prevents the accumulated lint and the like from clogging the air collecting channel 17, causing a significant decrease in air volume and a deterioration in the drying effect, until the drying process cannot be carried out; at the same time, when the rear temperature sensor 33 is set in the adapter 5, lint and the like are easily accumulated on the surface of the rear temperature sensor in the adapter 5, causing distortion of the temperature detected by the rear temperature sensor, affecting the judgment of the drying process.

[0100] A debris filter nozzle 6 is provided at the air inlet 171 of the air collecting channel 17 to flush the inner rear wall 11 of the outer tub 1 and the outer rear wall 21 of the drum 2 during the washing and drying processes. During the washing and drying processes, the drum 2 is controlled to rotate at a certain speed so that the water directly impacting and splashing can cover the drum 2 and the rear area of ​​the outer tub 1 to clean them.

[0101] The washing machine of the present invention has a washing function and a drying function at the same time, effectively improves the drying efficiency, ensures the drying effect, and improves the user experience.

[0102] Based on the structure of the above-mentioned washing machine, this embodiment provides a method for cleaning the drum of a washing machine, wherein the drum includes an inner drum and an outer drum of the washing machine, and the outer drum and the inner drum are cleaned by controlling the water supply to the debris filter nozzle. Specifically, when the user selects the washing-drying program, the drum cleaning step can be performed before rinsing the laundry to remove the fiber debris between the inner drum and the outer drum. This is because the fiber debris separated from the outer rear wall of the inner drum and the inner rear wall of the outer drum when cleaning the drum can be discharged together with the rinsing water supplied for rinsing. When the user chooses to perform a drying program alone, the drum cleaning step is performed before drying begins to remove the fiber debris between the inner drum and the outer drum; the removed hair debris can be discharged by performing a drainage action to discharge the fiber debris separated from the outer rear wall of the inner drum and the inner rear wall of the outer drum.

[0103] The following is a detailed description of the cleaning method of the cylinder:

[0104] The drum cleaning method of a washing machine includes: a drum cleaning program, which includes an interval cleaning step of controlling the opening and closing of a cleaning water valve to provide cleaning water to a debris filter nozzle, and a continuous cleaning step of controlling the cleaning water valve to be continuously opened after the interval cleaning step.

[0105] The drum cleaning procedure is as follows: the cleaning water valve is controlled to open and close intermittently for 1 to 2 seconds. After a cumulative time of 16 to 32 seconds, the cleaning water valve is opened and held for 5 to 20 seconds before being closed. This drum cleaning procedure can be repeated 2 or 3 times.

[0106] Furthermore, while the interval cleaning step is being performed, the inner drum is controlled to rotate forward and reverse, and the fan is activated to utilize the suction force of the fan to clean the drying duct. After the interval cleaning step is completed, the fan is controlled to continue to run for a predetermined time, and the heater is activated to heat and evaporate the remaining moisture in the drying duct.

[0107] like Figure 29 As shown, the specific contents of the barrel cleaning procedure are as follows:

[0108] When the user selects the washing-drying program, the drum cleaning program is executed before the rinsing process begins. The cleaning water valve is opened and closed intermittently so that cleaning water is intermittently supplied to the cleaning water inlet column, and cleaning water is sprayed between the inner drum and the outer drum through the debris filter nozzle. The cleaning water valve is intermittently supplied for a certain period of time, and then the cleaning water valve is continuously opened for continuous cleaning for a certain period of time.

[0109] The reason for intermittently supplying cleaning water is that, when the pressure of the supplied cleaning water is low, the spray pressure of the cleaning water can be temporarily increased compared to when the cleaning water is continuously supplied. Specifically, closing the cleaning water valve temporarily increases the pressure of the cleaning water controlled by the cleaning water valve. As the pressure of the cleaning water increases intermittently, the cleaning water supplied from the condensed water supply device is sprayed at a pressure slightly higher than the supply pressure.

[0110] Exemplarily, cleaning water is intermittently supplied to the filter nozzle at intervals of about 1 second. That is, the cleaning water valve is opened for 1 second to supply cleaning water, and then closed for 1 second to stop the supply of cleaning water. This process is repeated. Such a process of intermittently supplying cleaning water is called "interval cleaning". Preferably, the duration of the interval cleaning is 16s to 32s; in this embodiment, the cleaning water valve is controlled to be intermittently opened and closed for 1 second respectively, and the interval cleaning execution time is 20s, that is, the opening and closing of the clean water valve is repeated 10 times. The above-mentioned interval cleaning can exert an impact force on the fiber scraps tightly attached to the outer rear wall of the inner cylinder and the inner rear wall of the outer cylinder, making the fiber scraps fluid.

[0111] In addition, when the cleaning water valve is opened for the first time, the fan starts and uses the suction force of the fan to clean the fiber debris on the surface of the fan blades and the air duct.

[0112] After the interval cleaning of the wash water, the wash water valve is opened for a predetermined time to continuously supply wash water. The continuous supply of wash water lasts approximately 5 to 20 seconds. This process of continuously supplying wash water is referred to herein as "continuous cleaning." In this embodiment, the continuous cleaning is performed for 10 seconds to thoroughly clean the outer rear wall of the inner tub and the inner rear wall of the outer tub. This continuous cleaning process separates fluid lint from the outer rear wall of the inner tub and the inner rear wall of the outer tub.

[0113] When the cleaning water valve is opened for continuous cleaning, the inner drum rotates forward and reversely at a speed of 40-60 rpm to drive the water to move, so that the directly impacted or splashed water can clean and cover the outer rear wall area of ​​the inner drum and the inner rear wall area of ​​the outer drum.

[0114] During the above cleaning process, the drain pump does not operate, that is, remains in a closed state.

[0115] As needed, repeat the above cylinder cleaning procedure 2 or 3 times.

[0116] After cleaning, the fan continues to work for a certain period of time, and at the same time, the heater is turned on to heat and evaporate the remaining moisture in the air duct to keep the drying air duct free of water and avoid corrosion to the drying air duct.

[0117] Preferably, the above cleaning procedure is not carried out simultaneously with the supply of rinsing water or other water. That is, when the supply pressure of the cleaning water is lower than the normal pressure, if the supply of rinsing or other water and the supply of cleaning water are carried out simultaneously, the pressure of the cleaning water supplied will become lower.

[0118] The time and number of times the cleaning water valve is opened and closed during the above interval cleaning, as well as the time and number of times the continuous cleaning is performed, allow users to customize and select according to their needs to achieve better cleaning results.

[0119] When the user chooses to execute the drying program separately, the drum cleaning program is executed before the drying program starts. The cleaning water valve is opened and closed intermittently, so that the cleaning water is intermittently supplied to the cleaning water inlet column, and the cleaning water is sprayed between the inner drum and the outer drum through the debris filter nozzle. The cleaning water valve is intermittently supplied for a certain period of time, and then the cleaning water valve is continuously opened for continuous cleaning for a certain period of time.

[0120] The reason for intermittently supplying cleaning water is that, when the pressure of the supplied cleaning water is low, the spray pressure of the cleaning water can be temporarily increased compared to when the cleaning water is continuously supplied. Specifically, closing the cleaning water valve temporarily increases the pressure of the cleaning water controlled by the cleaning water valve. As the pressure of the cleaning water increases intermittently, the cleaning water supplied from the condensed water supply device is sprayed at a pressure slightly higher than the supply pressure.

[0121] Exemplarily, cleaning water is intermittently supplied to the filter nozzle at intervals of about 1 second. That is, the cleaning water valve is opened for 1 second to supply cleaning water, and then closed for 1 second to stop the supply of cleaning water. This process is repeated. Such a process of intermittently supplying cleaning water is called "interval cleaning". Preferably, the duration of the interval cleaning is 16s to 32s; in this embodiment, the cleaning water valve is controlled to be intermittently opened and closed for 1 second respectively, and the interval cleaning execution time is 20s, that is, the opening and closing of the clean water valve is repeated 10 times. The above-mentioned interval cleaning can exert an impact force on the fiber scraps tightly attached to the outer rear wall of the inner cylinder and the inner rear wall of the outer cylinder, making the fiber scraps fluid.

[0122] In addition, when the cleaning water valve is opened for the first time, the fan starts and uses the suction force of the fan to clean the fiber debris on the surface of the fan blades and the air duct.

[0123] After the interval cleaning with the wash water, the wash water valve is opened for a predetermined time to continuously supply wash water. The continuous supply of wash water typically lasts for approximately 5 to 20 seconds. This process of continuously supplying wash water is referred to herein as "continuous cleaning." In this embodiment, the continuous cleaning is performed for 10 seconds to thoroughly clean the outer rear wall of the inner tub and the inner rear wall of the outer tub. This continuous cleaning process separates fluid lint from the outer rear wall of the inner tub and the inner rear wall of the outer tub.

[0124] When the cleaning water valve is opened for continuous cleaning, the inner drum rotates forward and reversely at a speed of 40-60 rpm to drive the water to move, so that the directly impacted or splashed water can clean and cover the outer rear wall area of ​​the inner drum and the inner rear wall area of ​​the outer drum.

[0125] During the drum cleaning and drying procedures, the drainage pump remains open for 15 to 25 seconds in the second minute to drain water and discharge the cleaned fiber debris and the like separated from the outer rear wall of the inner drum and the inner rear wall of the outer drum.

[0126] As needed, repeat the above cylinder cleaning procedure 2 or 3 times.

[0127] After cleaning, the fan continues to work for a certain period of time, and at the same time, the heater is turned on to heat and evaporate the remaining moisture in the air duct to keep the drying air duct free of water and avoid corrosion to the drying air duct.

[0128] Preferably, the above cleaning procedure is not carried out simultaneously with the supply of rinsing water or other water. That is, when the supply pressure of the cleaning water is lower than the normal pressure, if the supply of rinsing or other water and the supply of cleaning water are carried out simultaneously, the pressure of the cleaning water supplied will become lower.

[0129] The time and number of times the cleaning water valve is opened and closed during the above interval cleaning, as well as the time and number of times the continuous cleaning is performed, allow users to customize and select according to their needs to achieve better cleaning results.

[0130] The present invention provides a drum cleaning method for a washing machine, which can remove fiber scraps and the like remaining between the inner drum and the outer drum to prevent the fiber scraps and the like from easily entering the gap, thereby maintaining the continued good performance of the washing machine; and effectively prevent the breeding of details and improve the user experience.

[0131] The above description is merely a preferred embodiment of the present invention and does not constitute any other form of limitation to the present invention. Any person skilled in the art may utilize the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes for application in other fields. However, any simple modification, equivalent change, and modification of the above embodiments made in accordance with the technical essence of the present invention without departing from the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
