Description

Technical Field

[0001] This application relates to the field of cleaning appliance technology, and more particularly to a drum washing machine. Background Technology

[0002] Front-loading washing machines are cleaning machines that use electrical energy to generate mechanical action to wash clothes. They are now widely used in households. Currently, some front-loading washing machines integrate a drying function. Specifically, a drying duct is set up on the outer drum of the washing machine, inside which a dryer and a fan are installed. An air outlet is located at the bottom of the outer drum, and an air inlet is located at one end of the drying duct, while an air outlet is located at the other end. The air inlet and outlet are connected, and the air outlet is connected to the front opening of the outer drum, thus forming a circulating air duct. The fan is located at the air inlet and is used to draw air from inside the outer drum and send it into the dryer. After being heated by the dryer into dry, high-temperature air, it flows back into the outer drum to dry the clothes.

[0003] However, with continued use of the washing machine, lint will accumulate in the drying duct, the impeller of the fan, the air outlet of the outer drum, and the temperature probe of the air inlet. Once enough lint has accumulated, it will block the duct and the impeller, affecting the operation of the fan and the drying efficiency of the dryer.

[0004] In related technologies, a connector is installed between the air inlet and the air outlet, and a nozzle is installed inside the connector. The nozzle is used to spray water to rinse the air outlet to prevent the accumulation of lint. However, in this method, the air outlet and the air inlet are not in the same position, and the nozzle has a single function, which can only rinse a single position and cannot take care to rinse lint in different positions.

The second annular rib is sleeved outside the first annular rib. The first and second annular ribs are in close contact with the connector to form the flushing chamber, and the first through hole constitutes the ventilation hole.

[0009] In one exemplary embodiment of this disclosure, the wall of the first through hole protrudes toward the outer peripheral wall of the outer cylinder to form a third annular rib, and the connector also protrudes toward the outer peripheral wall of the outer cylinder to form a fourth annular rib and a fifth annular rib. The fourth annular rib is sleeved on the third annular rib, and a first sealing groove corresponding to the direction of the first annular rib is formed between the two. The first annular rib is closely connected in the first sealing groove.

[0010] The fifth annular rib is sleeved outside the fourth annular rib and spaced apart from the side circumference. A second sealing groove is formed between the two, corresponding to the direction of the second annular rib. The second annular rib is closely connected in the second sealing groove, wherein the second annular rib extends along the outer edge of the rinsing plate.

[0011] In one exemplary embodiment of this disclosure, the third annular rib protrudes toward the center of the first through hole to form a boss, and the side of the boss facing the air inlet has the first flushing hole.

Detailed Implementation

[0031] To make the objectives and implementation methods of this application clearer, the exemplary implementation methods of this application will be clearly and completely described below with reference to the accompanying drawings of the exemplary embodiments of this application. Obviously, the exemplary embodiments described are only some embodiments of this application, and not all embodiments.

[0032] It should be noted that the brief descriptions of terms in this application are only for the convenience of understanding the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise stated, these terms should be understood in their ordinary and common meaning.

[0033] The terms "first," "second," "third," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar or related objects or entities, and do not necessarily imply a specific order or sequence, unless otherwise specified. It should be understood that such terms are interchangeable where appropriate.

[0034] The terms “include” and “have”, and any variations thereof, are intended to cover but not exclusively include, for example, a product or device that includes a range of components is not necessarily limited to all of the components that are clearly listed, but may include other components that are not clearly listed or that are inherent to such product or device.

[0035] With continued use of the washing machine, lint will accumulate in the drying duct, at the impeller of the fan, at the air outlet of the outer drum, and at the temperature probe of the air inlet. Once enough lint has accumulated, it will block the duct and impeller, affecting the operation of the fan and the drying efficiency of the dryer.

[0036] In related technologies, a connector is installed between the air inlet and the air outlet, and a nozzle is installed within the connector. The nozzle sprays water onto the air outlet to prevent lint accumulation. However, this method results in the air outlet and the air inlet being misaligned, and the nozzle has a limited function, only able to rinse a single location, failing to address lint accumulation in different areas. To solve this problem, this application provides a drum washing machine.

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

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

[0039] See Figure 1 A drum washing machine includes a cabinet, an outer drum 1, a drying air duct 2, and a washing component 3.

[0040] The cabinet is the external structure of the drum washing machine. It is a hollow structure with a rectangular outer perimeter and an internal space, which can house other components of the drum washing machine, such as circuit structure, air duct structure, drive mechanism and drainage structure.

[0041] The outer cylinder 1 is set inside the box and is fixedly supported inside the box. The inner cylinder is provided inside the outer cylinder 1 and is rotatably set in the outer cylinder 1. A rotating shaft is provided on the axis of the outer cylinder 1, which passes through the rear wall of the outer cylinder 1 and is connected to the inner cylinder.

[0042] The front of the box has an opening with a door for closing it. One end of the outer tube 1 has a clothing inlet 11, which corresponds to the front opening of the box. This allows clothing to be placed into the inner tube through the clothing inlet 11 after the door is opened. The clothing inlet 11 of the outer tube 1 is also equipped with a door seal to seal the door when it is closed. The door seal also prevents foreign objects from entering between the outer tube 1 and the inner tube.

[0043] In this embodiment, the drying duct 2 is disposed on the outer peripheral wall of the outer cylinder 1. A dryer and a fan 22 are disposed inside the drying duct 2. An air inlet 21 and an air outlet are respectively provided at both ends of the drying duct 2. An air outlet 13 is provided on the outer peripheral wall of the outer cylinder 1. The air outlet and the clothes loading port 11 are connected, and the air inlet 21 and the air outlet 13 are connected, thus forming an air circulation channel between the drying duct 2 and the outer cylinder 1. The dryer is used to heat and dry the air inside the drying duct 2. The fan 22 is disposed near the air inlet 21, with its impeller located at the air inlet 21, to guide air from the outer cylinder 1 to the drying duct 2 and into the dryer, thereby accelerating air circulation and continuously drawing humid air from the outer cylinder 1 to the dryer for heating and drying the clothes.

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

[0045] Figure 2 A front view of the outer drum of a drum washing machine according to some embodiments is shown; Figure 3 It shows Figure 2 A cross-sectional view along the AA direction; Figure 4 It shows Figure 3 A magnified view of a section at point B.

[0046] See also Figures 2 to 4 The inner bottom of the outer cylinder 1 protrudes outward to form an air collecting groove 12. One end of the air collecting groove 12 extends through the outer peripheral wall of the outer cylinder 1 to form an air outlet 13. The air inside the outer cylinder 1 is first 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 conducive to the concentration of air, and can slow down the air flow rate, reduce noise, and make the air flow smoothly towards the air outlet 13.

[0047] Understandably, in order to prevent impurities from clothing from being sucked into the drying air duct 2, a filter element 14 is also provided at the bottom of the outer cylinder 1 in front of the air collection groove 12. The filter element 14 has filter holes. The air in the outer cylinder 1 enters the air collection groove 12 after passing through the filter holes, and then enters the drying air duct 2 through the air outlet 13.

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

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

[0050] In this embodiment, the rinsing component 3 includes a rinsing section and a side enclosure 31 surrounding the rinsing section, forming a cylindrical structure with one open end. The side enclosure 31 is sealed to the outer peripheral wall of the outer cylinder 1. The rinsing section, the side enclosure 31, and the outer peripheral wall of the outer cylinder 1 together form a flow channel. The air outlet 13 is located inside the flow channel, and the air coming out of the air outlet 13 first enters the flow channel. The side of the rinsing section away from the outer peripheral wall of the outer cylinder 1 is sealed to the end of the drying air duct 2 that has an air inlet 21. The rinsing section has a ventilation hole 35, which is correspondingly arranged with the air inlet 21 to connect the flow channel and the drying air duct 2. After passing through the flow channel and the ventilation hole 35, the air is drawn into the drying air duct 2 by the fan 22. The side enclosure 31 is provided to seal using the outer peripheral wall of the outer cylinder 1, simplifying the sealing structure of the rinsing component 3 and preventing air leakage. At the same time, the side enclosure 31 is in direct contact with the outer cylinder 1, and the outer cylinder 1 provides greater support, which can better support and fix the drying air duct 2.

[0051] In some embodiments, the rinsing section is further provided with a rinsing chamber 34 surrounding the ventilation hole 35. The rinsing chamber 34 is connected to a water source. The rinsing section is provided with a first rinsing hole 341 and a second rinsing hole 342 connected to the rinsing chamber 34. The first rinsing hole 341 and the second rinsing hole 342 are respectively opened towards the air inlet 21 and the air outlet 13. After water enters the rinsing chamber 34, it washes the impeller of the fan 22 and the air collection groove 12, thereby rinsing the accumulated lint in the air inlet 21, the fan 22, the air outlet 13 and the air collection groove 12. By utilizing the formed rinsing chamber 34, the rinsing range is expanded, and rinsing holes can be led out in all directions to rinse multiple parts, solving the problem of a single rinsing part in the prior art and reducing lint accumulation.

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

Figure 1 ; Figure 6 An exemplary schematic diagram of the structure of the washing component of a drum washing machine according to some embodiments is shown. Figure 2 ; Figure 7 An exemplary schematic diagram of the structure of the washing component of a drum washing machine according to some embodiments is shown. Figure 3 ; Figure 8 It shows Figure 7 A cross-sectional view along the CC direction.

[0054] In some embodiments, see continue to see Figures 5 to 8The rinsing section includes a connector 32 and a rinsing disc 33. A side panel 31 is connected to the edge of the connector 32 and can be integrally formed with the connector 32, thus forming a cylindrical structure with one open end. The rinsing disc 33 is sealed inside the side panel 31 and has a certain distance from the connector 32. The space between the two defines a rinsing chamber 34, making the rinsing chamber 34 a sealed space that can store water without leakage. The rinsing chamber 34 is formed by two components enclosing each other, which facilitates the combination of the two components after they are individually formed. Of course, in some embodiments, the rinsing chamber 34 can be a cavity opened inside the rinsing section itself, with the connector 32 and the rinsing disc 33 integrally formed. The drying duct 2 has an air inlet 21 at one end which is sealed to the connector 32. The connector 32 connects the drying duct 2 to the outer peripheral wall of the outer cylinder 1. The rinsing plate 33 faces the outer peripheral wall of the outer cylinder 1. The first rinsing hole 341 can be opened on the wall of the ventilation hole 35 so that it can be rinsed towards the air inlet 21, while the second rinsing hole 342 can be opened on the rinsing plate 33 so that it can be rinsed towards the air outlet 13.

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

[0056] The connector 32 and the flushing plate 33 penetrate through the air inlet 21 at their corresponding positions to form a ventilation hole 35. Specifically, the connector 32 has a first through hole 36 through it at the position corresponding to the air inlet 21, and the flushing plate 33 has a second through hole 37 through it at the position corresponding to the air inlet 21. The second through hole 37 is fitted outside the first through hole 36, and the diameter of the second through hole 37 is larger than that of the first through hole 36. The two are coaxially arranged. The 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 rib 331. The rinsing plate 33 also protrudes in the direction away from the outer peripheral wall of the outer cylinder 1 to form a second annular rib 332. The inner diameter of the second annular rib 332 is larger than the inner diameter of the first annular rib 331. The second annular rib 332 is sleeved on the outside of the first annular rib 331. The two are in close contact with the connector 32, so that there is a gap between the rinsing plate 33 and the connector 32 to form a rinsing cavity 34. In this case, the first annular rib 331, the second annular rib 332, the connector 32 and the rinsing plate 33 surround and form the rinsing cavity 34.

[0057] Understandably, after the second through hole 37 is fitted outside the first through hole 36, the first through hole 36 forms a ventilation hole 35, and air flows through the first through hole 36 from the flow channel to the air inlet 21. When the connector 32 is connected to the drying air duct 2, the end of the drying air duct 2 with the air inlet 21 is supported on the connector 32. The inner wall of the air inlet 21 protrudes towards the outer peripheral wall of the outer cylinder 1 to form a convex edge. The convex edge is inserted into the first through hole 36, thereby realizing the connection between the air inlet 21 and the ventilation hole 35. A sealing ring can also be set between the two to improve the sealing performance and prevent air leakage.

[0058] In some embodiments, the wall of the first through hole 36 protrudes towards the outer peripheral wall of the outer cylinder 1 to form a third annular rib 321, and the connector 32 also protrudes towards the outer peripheral wall of the outer cylinder 1 to form a fourth annular rib 322 and a fifth annular rib 323. The inner diameter of the third annular rib 321 is smaller than the inner diameter of the fourth annular rib 322. The fourth annular rib 322 is sleeved on the outside of the third annular rib 321, and a first sealing groove 324 corresponding to the direction of the first annular rib 331 is formed between the two. The first annular rib 331 is tightly connected in the first sealing groove 324, so that the first annular rib 331 and the first sealing groove 324 are pressed and contacted, and the two abut against each other, achieving good sealing while clamping the first annular rib 331, and preventing air leakage from the first sealing groove 324.

[0059] Correspondingly, the inner diameter of the fifth annular rib 323 is larger than that of the fourth annular rib 322. The fifth annular rib 323 is sleeved outside the fourth annular rib 322 and spaced apart from the side circumference 31. A second sealing groove 325 is formed between them, corresponding to the orientation of the second annular rib 332. The second annular rib 332 is tightly fitted into the second sealing groove 325, allowing the second annular rib 332 and the second sealing groove 325 to press against each other, achieving good sealing while securing the second annular rib 332 and preventing air leakage from the second sealing groove 325. By forming the first sealing groove 324 and the second sealing groove 325 with the protruding third annular rib 321, fourth annular rib 322, and fifth annular rib 323, the distance between the connector 32 and the flushing disc 33 can be increased, the volume of the flushing chamber 34 can be increased, more water 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 partially recessed in the connector 32 itself.

[0061] In some embodiments, the second annular rib 332 extends along the outer edge of the flushing disc 33, thereby maximizing the coverage area of ​​the flushing chamber 34 and allowing more flushing holes to be flushed. Simultaneously, the space between the side panel 31 and the fifth annular rib 323 forms a second sealing groove 325, further maximizing the coverage area of ​​the flushing chamber 34. This also allows the flushing disc 33 to be securely held within the side panel 31, facilitating its installation.

[0062] In some embodiments, the flushing plate 33 and the connector 32 are provided with screw posts at corresponding positions. The two screw posts face each other and are screwed together to form a screw group. Multiple screw groups can be provided between the flushing plate 33 and the connector 32 to fix the two together and facilitate installation and disassembly.

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

[0064] The fourth annular rib 322 and the third annular rib 321 have corresponding orientations. Thus, the fourth annular rib 322, at the position where it protrudes to form the boss 326 corresponding to the third annular rib 321, also protrudes synchronously towards the center of the first through hole 36. This ensures that the width of the first sealing groove 324 is equal at all positions, facilitating the tight fit of the first annular rib 331 within the first sealing groove 324. The first flushing hole 341 is located outside the fourth annular rib 322, allowing it to communicate with the flushing chamber 34. It can be understood that the inner side of the fourth annular 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 sidewall 31.

[0065] Figure 9 An exemplary schematic diagram of the structure of a connector for a drum washing machine according to some embodiments is shown; Figure 10 An exemplary schematic diagram of the structure of the wash tray of a drum washing machine according to some embodiments is shown.

[0066] In some embodiments, see continue to see Figure 9 and Figure 10The first annular rib 331 protrudes towards the center of the second through hole 37 to form a sealing part 333 covering the boss 326. The sealing part 333 is arranged one-to-one with the boss 326. In this way, after the first annular rib 331 is inserted into the first sealing groove 324 at the corresponding position of the boss 326, the sealing part 333 can block the corresponding boss 326 and seal it. The sealing part 333 has a third flushing hole 343 on its side that communicates with the flushing chamber 34. The third flushing hole 343 is opened towards the side wall 31 to flush the side wall 31 and the flushing plate 33, thereby cleaning the lint accumulated on both.

[0067] The sealing part 333 is recessed towards the outer peripheral wall of the outer cylinder 1 to form a recessed platform 334. The edge of the recessed platform 334 is connected to the first annular rib 331. The recessed platform 334 corresponds to the protrusion 326 to cover the protrusion 326. The side of the recessed platform 334 is provided with the third flushing hole 343, so that it can spray flushing towards the side wall 31 and the flushing plate 33.

[0068] In some embodiments, multiple bosses 326 are spaced apart around the first through hole 36. Each boss 326 has the first flushing hole 341 on the side facing the air inlet 21, thereby enabling all-round flushing of the air inlet 21 and the impeller of the fan 22, improving flushing efficiency and quality. The number of bosses 326 is determined according to the actual situation. In this embodiment, three bosses 326 are spaced apart around the first through hole 36. Of course, there can also be two, four, etc.

[0069] It is understood that the number and position of the sealing parts 333 correspond to the boss 326. In this embodiment, three sealing parts 333 are arranged circumferentially along the second through hole 37. At the same time, in order to expand the rinsing range of the side wall 31 and the rinsing plate 33, a third rinsing hole 343 is provided on both opposite sides of the sealing parts 333. Multiple sealing parts 333 have multiple third rinsing holes 343, thereby rinsing the side wall 31 and the rinsing plate 33 in all directions and preventing the accumulation of lint on them.

[0070] In some embodiments, to enhance the connection stability of the connector 32 and the flushing disc 33 and improve the sealing performance between them, the sealing part 333 is provided with a latch 335 at one end near the center of the second through hole 37, and the boss 326 is provided with a latch 327 that engages with the latch 335 at one end near the center of the first through hole 36, so that the latch 327 is engaged in the latch 335 for connecting the flushing disc 33 and the connector 32. During initial installation, after aligning the flushing disc 33 and the connector 32, they are first connected using the latch 327, and finally fixed using screw posts, thereby improving connection reliability. The latch 327 connection also makes the connection between the sealing part 333 and the boss 326 tighter, enhancing the sealing performance at this location.

[0071] In some embodiments, the end of the sealing part 333 near the center of the second through hole 37 extends towards the center of the second through hole 37 and then extends towards the air inlet 21 to form an L-shaped elastic arm. An opening is provided on the L-shaped elastic arm, which constitutes the buckle 335. When the flushing disc 33 is installed, after the flushing disc 33 abuts against the connector 32, the buckle 327 is engaged in the buckle 335, so that the two are fastened together.

[0072] In some embodiments, a mounting hole 311 is provided on the side panel 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 panel 31 to detect the temperature at the air inlet 21. When the temperature reaches a threshold, it indicates that the air coming out of the outer cylinder 1 is hot air, the drying is complete, and the operation of the dryer ends. The rinsing plate 33 has a fourth rinsing hole 344 communicating with the rinsing chamber 34. The fourth rinsing hole 344 is adjacent to and faces the temperature sensor 4, so that after long-term use, the temperature sensor 4 is rinsed to prevent the accumulation of lint and debris, which would affect its detection accuracy.

[0073] In some embodiments, the rinsing disc 33 is at least partially opposite the air outlet 13, and multiple second rinsing holes 342 are provided and spaced apart on the portion of the rinsing disc 33 opposite the air outlet 13, thereby directly rinsing the air outlet 13, the air collection groove 12, and the filter element 14. The ejection angles of the multiple second rinsing holes 342 may be different, and the intervals between the second rinsing holes 342 at different positions are relatively large, so as to be able to rinse the air collection groove 12 at different positions.

[0074] In summary, in this embodiment, by setting up a rinsing chamber 34, the area for setting up rinsing holes is expanded, thereby enabling the setting of rinsing holes facing different objects as needed, such as the first rinsing hole 341, the second rinsing hole 342, the third rinsing hole 343, and the fourth rinsing hole 344 in this embodiment. This allows for rinsing different objects at different locations, solving the problem of a single rinsing position in the prior art, improving the lint removal capability at each location, thus avoiding lint accumulation and improving drying efficiency.
