Description

Technical Field

[0001] This invention relates to the field of household appliance technology, specifically to a washer-dryer combo and its control method. Background Technology

[0002] With the advancement of technology and the improvement of people's living standards, heat pump washing machines or washer-dryer combos are playing an increasingly important role. However, existing washer-dryer combos are prone to lint buildup during the drying process due to clothing wear and tear, which can clog the air ducts and directly affect the drying efficiency and effectiveness.

[0003] To address this issue, current practices typically involve installing a filter at the air inlet of the duct to remove lint. However, as lint accumulates, more lint adheres to the filter, causing it to become clogged and affecting drying efficiency. Consequently, users need to clean the filter frequently, which is time-consuming and laborious.

[0004] Currently, most washing machines on the market with self-cleaning filters have front and rear air intakes and rely on the water flow driven by rotational inertia to work with the spray nozzles for filter self-cleaning. However, the filter cannot achieve complete self-cleaning solely through the water flow driven by rotational inertia. When fine lint adheres to the filter, it becomes difficult to clean. If the drying function is activated while the filter is still clogged, the lint will adhere even more firmly, leading to an accumulation that is impossible to remove. After several cycles, the filter will still become clogged, and the drying effect of the washing machine will deteriorate over time, eventually requiring professional technicians to perform on-site maintenance. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a washer-dryer combo machine to solve the problems of poor drying effect and difficult maintenance caused by incomplete self-cleaning of the filter.

[0006] To achieve the above objectives, the invention employs the following technical solution:

[0007] A washer-dryer combo includes an outer drum, an inner drum, and an air duct. The inner drum is rotatably disposed inside the outer drum. The air duct has an air inlet communicating with the outer drum, and a filter screen is disposed on the air inlet.

[0008] The air inlet is located on the wall surface of the outer cylinder that extends out of the inner cylinder opening, so that when the inner cylinder rotates, the filter screen can generate friction with the clothes inside the inner cylinder.

[0009] In the washer-dryer of this application, the air inlet of the air duct is located on the wall surface where the outer drum extends out of the inner drum opening. In this way, the clothes in the inner drum can come into contact with and rub against the filter screen. During washing, the wet clothes and water whip / rub against the filter screen during rotation, continuously washing and cleaning the filter screen. During drying, the clothes will also come into contact with and rub against the filter screen during rotation, continuing to wash and clean the filter screen.

[0010] As can be seen, the washer-dryer of this application not only allows the filter to self-clean during the washing process by relying on the rotational inertia of the water flow, but also allows it to whip / touch and rub against the clothes during the washing and drying process, thus achieving the effect of cleaning stubborn lint. This method of washing / drying at the same time greatly improves the filter cleaning effect compared to the existing simple water flow rinsing cleaning method, thereby solving the problems of poor drying effect and difficult maintenance caused by incomplete self-cleaning of the filter.

[0011] In some embodiments, the air outlet of the air duct is located on the wall surface of the outer cylinder extending from the opening of the inner cylinder. In this embodiment of the washer-dryer, both the air inlet and outlet of the air duct are located on the wall surface at the opening end of the outer cylinder, which makes the arrangement of the air duct more convenient and simplifies the structure of the air duct.

[0012] In some embodiments, the washer-dryer combo also includes a door with a glass bowl that can extend into the outer drum;

[0013] The glass bowl has an inclined surface on the side opposite the air outlet to refract the airflow from the air outlet into the interior of the inner cylinder.

[0014] In this washer-dryer, when the air outlet of the air duct is located on the wall of the open end of the outer drum, the airflow blown out of the air outlet can be refracted into the interior of the inner drum by the inclined surface of the glass bowl, so as to ensure the drying effect of the clothes.

[0015] In some embodiments, the angle between the inclined surface and the air outlet direction is 40° to 50°.

[0016] The washer-dryer combo implemented here is designed with an angle of 40° to 50° between the inclined surface and the air outlet direction, which can refract the airflow blown out of the air outlet into the inner drum to the maximum extent, thereby improving the drying effect of clothes.

[0017] In some embodiments, the inclined surface is provided with first ribs spaced apart along the direction away from the air outlet, so that the inclined surface has a wave structure.

[0018] The washer-dryer combo of this implementation features a sloping wave structure that diffuses the airflow, making it more evenly distributed within the inner drum. This disperses heat throughout the drum, resulting in more uniform heating of the clothes and improved drying efficiency and effect.

[0019] In some embodiments, the first rib is a first arc-shaped strip protruding from the inclined surface, and the central angle corresponding to the first arc-shaped strip is 40° to 120°.

[0020] The washer-dryer combo implemented in this invention features a first rib structure design that maximizes the diffuse scattering effect of the wave structure, further improving the uniformity of airflow distribution within the drum and enhancing drying efficiency and effect.

[0021] In some embodiments, the glass bowl also has a bowl surface that can come into contact with clothing;

[0022] The bowl surface is provided with second ribs at intervals, which makes the bowl surface have a wave structure.

[0023] In this washer-dryer combo, the glass bowl in contact with the clothes is also designed with a wave-like structure, which creates a rubbing effect between the clothes and the glass bowl. Washing and rubbing are carried out simultaneously, resulting in better washing effect and reducing washing time. This achieves the goals of energy saving, time saving, and high efficiency.

[0024] In some embodiments, the second rib is a second arcuate strip protruding from the surface of the bowl, and the central angle corresponding to the second arcuate strip is 115° to 180°.

[0025] The washer-dryer combo of this implementation features a second rib design that maximizes the rubbing effect of the wave structure and prevents excessive friction between the wave structure and the clothes, thus avoiding damage.

[0026] In some embodiments, the outer cylinder and the inner cylinder are arranged horizontally along their axes;

[0027] The air inlet and outlet of the air duct are distributed on the left and right sides of the outer cylinder wall.

[0028] The washer-dryer combo implemented here is a drum-type washing machine. The air inlet and outlet of the air duct are distributed on the left and right sides of the wall at the opening end of the outer drum. This left and right air inlet and outlet design can not only ensure the whipping / touching friction effect between the clothes and the filter, but also facilitate the filter to achieve self-cleaning by relying on the water flow of rotational inertia.

[0029] In some embodiments, the water inlet of the outer cylinder is disposed adjacent to the air inlet and located above the air inlet.

[0030] In this washer-dryer, the water inlet is located above the air inlet. When water enters, the water flow directly hits the filter screen, providing a preliminary cleaning effect. After water enters, the rinsing process begins. The wet clothes and water interact with the filter screen during rotation, creating a whipping / touching friction effect, which provides a secondary cleaning effect. During the drying process, the clothes also interact with the filter screen during rotation, providing a tertiary cleaning effect, thus achieving a thorough self-cleaning effect for the filter screen.

[0031] Compared with the prior art, the advantages of this invention are as follows:

[0032] 1. The air inlet of the air duct of the present invention is opened on the wall surface of the outer drum extending from the inner drum opening, so that the filter screen on it can come into contact and rub against the clothes. In this way, the filter screen can not only achieve self-cleaning by relying on the water flow of rotational inertia during the washing process, but more importantly, during the washing and drying process, the clothes will whip / touch and rub against the filter screen to achieve the effect of cleaning stubborn lint. The filter screen is cleaned while being washed / dried, achieving thorough self-cleaning of the filter screen.

[0033] 2. The glass bowl of this invention adopts a wave-shaped design. The sloping wave structure can diffuse the airflow blown from the air outlet of the air duct to all parts of the inner drum, so that the heat is evenly distributed, improving the drying efficiency and drying effect. The wave structure on the bowl surface can generate a rubbing effect with the clothes during the operation of the inner drum, achieving a combination of machine washing and hand washing, resulting in better washing effect of the clothes, thereby achieving the purpose of energy saving, time saving and high efficiency.

[0050] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.

[0051] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0052] Currently, most washing machines on the market with self-cleaning filters have front and rear air intakes and rely on the water flow driven by rotational inertia to work with the spray nozzles for filter self-cleaning. However, the filter cannot achieve complete self-cleaning solely through the water flow driven by rotational inertia. When fine lint adheres to the filter, it becomes difficult to clean. If the lint cannot be cleaned and the drying function is then activated, it will adhere even more firmly, leading to an accumulation that is impossible to remove. After several cycles, the filter will still become clogged with dirt, and the drying effect of the washing machine will deteriorate over time, eventually requiring on-site maintenance by a professional technician.

[0053] Therefore, this application proposes a washer-dryer combo machine that can effectively solve the problems of poor drying effect and difficult maintenance caused by incomplete self-cleaning of the filter.

[0054] Example 1

[0055] See Figures 1 to 4 The washer-dryer combo of this embodiment includes an outer drum 1, an inner drum 2 and an air duct 3. The inner drum 2 is rotatably disposed inside the outer drum 1, and the air duct 3 is disposed outside the outer drum 1. The air inlet 31 of the air duct 3 is disposed on the wall surface of the outer drum 1 that extends out of the opening of the inner drum 2, and a filter screen is disposed on the air inlet 31.

[0056] Specifically, a washer-dryer combo includes a housing that forms the exterior of the combo and has an opening into which clothes are placed.

[0057] The outer tub 1 is a water container, fixed inside the casing. The outer tub 1 has an opening that aligns with the opening of the casing, allowing clothes to be put in and taken out through the opening of the outer tub 1.

[0058] The inner drum 2 is a roller for holding clothes, which is rotatably installed inside the outer drum 1. The inner drum 2 has an opening that is roughly aligned with the opening of the outer drum 1. Clothes can be put in and taken out through the opening of the inner drum 2. The opening of the inner drum 2 is located inside the outer drum 1 and is separated from the opening of the outer drum 1 along the rotation axis of the inner drum 2. That is, the opening of the outer drum 1 extends a certain distance beyond the opening of the inner drum 2.

[0059] The air duct 3 is installed inside the casing and is located outside the outer cylinder 1. It is used to provide circulating drying airflow to the inner cylinder 2. The air inlet 31 of the air duct 3 is opened on the wall surface of the opening of the outer cylinder 1. This wall surface extends out of the opening of the inner cylinder 2, so that the air inlet 31 is located outside the opening of the inner cylinder 2 in the direction of the rotation axis of the inner cylinder 2. In this way, the clothes in the inner cylinder 2 can extend out of the opening of the inner cylinder 2 and come into contact with the filter screen of the air inlet 31 during the rotation of the inner cylinder 2.

[0060] Applying the technical solution of this embodiment, since the clothes in the inner drum 2 can touch and rub against the filter screen of the air inlet 31 during the rotation process, on the one hand, during washing, the wet clothes and water whip / touch and rub against the filter screen during the rotation process, continuously washing and cleaning the filter screen; on the other hand, during drying, the clothes will also touch and rub against the filter screen during the rotation process, continuing to continuously wash and clean the filter screen.

[0061] In this way, the filter can not only self-clean itself by relying on the rotational inertia of the water flow during the washing process, but also whip / touch and rub against the clothes during the washing and drying process to achieve the effect of cleaning stubborn lint. This method of washing / drying at the same time greatly improves the cleaning effect of the filter compared with the existing simple water flow rinsing cleaning method, thereby solving the problem of poor drying effect and difficult maintenance caused by incomplete self-cleaning of the filter.

[0062] In this embodiment, the air inlet 31 of the air duct 3 is located on the wall surface of the opening of the outer drum 1, specifically, it is located on the wall surface around the opening of the outer drum 1 that extends beyond the opening of the inner drum 2. For a pulsator washing machine, that is, a washing machine with a vertically oriented drum, the air inlet 31 can be located at any position on the wall surface around the opening of the outer drum 1 that extends beyond the opening of the inner drum 2, and the self-cleaning effect of the filter will not be affected.

[0063] For front-loading washing machines, that is Figure 1 and Figure 2 In the washing machine with a horizontally arranged drum, the air inlet 31 can be located anywhere on the wall of the outer drum 1 extending from the opening of the inner drum 2. However, when the air inlet 31 is located at the top of the outer drum 1, during the low-speed rotation of the inner drum 2, the clothes are subjected to gravity and rotational inertia. At this time, the weight of the clothes is greater than the rotational inertia, so the clothes will fall off when the inner drum rotates to a certain position, thereby reducing the whipping / touching friction effect between the clothes and the filter screen. It is also not conducive to self-cleaning by the water flow relying on rotational inertia. When the air inlet 31 is located at the bottom of the outer drum 1, although it does not reduce the whipping / touching friction effect between the clothes and the filter screen, during the drainage process of the outer drum 1, lint in the water is easily deposited and left on the filter screen, affecting the self-cleaning effect of the filter screen. Therefore, the air inlet 31 is preferably located in the middle of the outer drum 1, that is, on the left or right side of the outer drum 1. In this way, the whipping / touching friction effect between the clothes and the filter screen can be guaranteed, and the filter screen can also achieve self-cleaning by the water flow relying on rotational inertia.

[0064] See Figure 3 and Figure 4 The air duct 3 also includes an air outlet 32. A heat exchange module 33 and a fan 34 are also arranged in sequence in the air duct from the air inlet 31 to the air outlet 32. Specifically, the heat exchange module 33 and the fan 34 are arranged in sequence in the air duct along the air inlet direction of the air duct 3, that is, the heat exchange module 33 is close to the air inlet 31 and the fan 34 is close to the air outlet 32.

[0065] The fan 34 draws airflow from the inner cylinder 2 into the air duct 3 and discharges it back into the inner cylinder 2 through the air outlet 32 ​​of the air duct 3, thus achieving airflow circulation. The heat exchange module 33 may include, for example, an evaporator and a condenser, which are arranged sequentially along the air inlet direction. The evaporator is used to cool and liquefy the water vapor in the airflow flowing from the inner cylinder 2 to achieve dehumidification. The condenser is used to heat the airflow, and after reaching the set drying temperature, the airflow flows back into the inner cylinder 2.

[0066] In this embodiment, the air outlet 32 ​​of the air duct 3 may not be equipped with a filter screen. Therefore, the position of the air outlet 32 ​​can be freely set. Specifically, the air outlet 32 ​​can be arbitrarily set along the axial direction of the outer cylinder 1. That is to say, the air outlet 32 ​​can be set at the open end of the outer cylinder 1, such as... Figure 1 As shown; the air outlet 32 ​​can also be set in the middle section of the outer cylinder 1, so as to maintain a certain axial distance from the air inlet 31; of course, the air outlet 32 ​​can also be set at the other end of the outer cylinder 1 away from the opening, so that the airflow can pass through the entire inner cylinder 2 axially.

[0067] Meanwhile, along the circumferential direction of the outer cylinder 1, the air outlet 32 ​​can be located on the same side as the air inlet 31, or on a different side. Preferably, as shown below... Figure 1 As shown, the air outlet 32 ​​and the air inlet 31 are arranged symmetrically on the left and right sides, so that the airflow can penetrate the entire inner cylinder 2 radially.

[0068] See Figure 2 The air inlet 31 of the air duct 3 is located in the middle left side of the outer cylinder 1. At the same time, the water inlet of the outer cylinder 1 is located in the upper left side of the outer cylinder 1. That is, the water inlet of the outer cylinder 1 is adjacent to the air inlet 31 of the air duct 3 and is located above the air inlet 31.

[0069] In this way, during the water intake process, under the action of water pressure and gravity, the water flow directly hits the filter screen, which plays a preliminary cleaning role; after the water intake is completed, the rinsing begins, and the wet clothes and water come into contact with and rub against the filter screen during the rotation, which achieves a secondary cleaning; during the drying process, the clothes also come into contact with and rub against the filter screen during the rotation, which achieves a tertiary cleaning. The filter screen can undergo three cleanings during the entire use process, achieving thorough self-cleaning of the filter screen.

[0070] The following is combined with Figure 1 and Figure 2 The usage process of the washer-dryer combo in this embodiment will be described.

[0071] Turn on the washing function: During the water intake process, the filter screen of the air inlet 31 is cleaned for the first time by the water pressure and gravity effect; after the water intake is completed, the inner drum 2 starts to rotate at a low speed, and the water flow of rotation inertia cleans the filter screen for the second time; when the inner drum 2 enters high-speed rotation / spin-drying high-speed rotation, the water flow of rotation inertia and the whipping / touching friction between the clothes and the filter screen perform a third thorough cleaning; throughout the washing process, the filter screen is cleaned gradually from shallow to deep.

[0072] Entering drying mode: Fan 33 starts and brings in hot air to blow onto inner drum 2. Inner drum 2 rotates to dry the clothes. At the same time, the clothes and filter are whipped / touched and rubbed to perform a fourth cleaning. The filter is also cleaned throughout the drying process.

[0073] As can be seen from the above description, in this embodiment of the washer-dryer, the air inlet of the air duct is opened on the wall surface of the outer drum extending from the inner drum opening, so that the filter screen on it can come into contact with and rub against the clothes. In this way, the filter screen can not only achieve self-cleaning by relying on the water flow of rotational inertia during the washing process, but more importantly, during the washing and drying process, the clothes will whip / touch and rub against the filter screen, achieving the effect of cleaning stubborn lint. The filter screen is cleaned while being washed / dried, achieving thorough self-cleaning of the filter screen.

[0074] Example 2

[0075] See Figures 5 to 8 The washer-dryer combo in this embodiment is a drum washing machine, including a casing, an outer drum 1, an inner drum 2, an air duct 3, and a door 4.

[0076] Specifically, the casing forms the exterior of the washer-dryer combo and has an opening for clothes to be placed inside; the outer drum 1 is a water tank fixed inside the casing, and the outer drum 1 has an opening that aligns with the opening of the casing, allowing clothes to be placed in and taken out through the opening of the outer drum 1.

[0077] The inner drum 2 is a roller for holding clothes, which is rotatably installed inside the outer drum 1. The inner drum 2 has an opening that is roughly aligned with the opening of the outer drum 1. Clothes can be put in and taken out through the opening of the inner drum 2. The opening of the inner drum 2 is located inside the outer drum 1 and is separated from the opening of the outer drum 1 along the rotation axis of the inner drum 2. That is, the opening of the outer drum 1 extends a certain distance beyond the opening of the inner drum 2.

[0078] The air duct 3 is installed inside the casing and is located outside the outer cylinder 1. The air inlet 31 of the air duct 3 is opened on the wall surface of the opening of the outer cylinder 1. This wall surface extends out of the opening of the inner cylinder 2, so that the air inlet 31 is located outside the opening of the inner cylinder 2 in the direction of the rotation axis of the inner cylinder 2. In this way, the clothes inside the inner cylinder 2 can extend out of the opening of the inner cylinder 2 and come into contact with the filter screen of the air inlet 31 during the rotation of the inner cylinder 2.

[0079] The door 4 is pivotally connected to the opening of the housing to open or close the opening of the outer cylinder 1. The door 4 is provided with a glass bowl 5 that can extend into the interior of the outer cylinder 1.

[0080] See Figure 3 and Figure 4 The air duct 3 also includes an air outlet 32. A heat exchange module 33 and a fan 34 are also arranged in sequence in the air duct from the air inlet 31 to the air outlet 32. Specifically, the heat exchange module 33 and the fan 34 are arranged in sequence in the air duct along the air inlet direction of the air duct 3, that is, the heat exchange module 33 is close to the air inlet 31 and the fan 34 is close to the air outlet 32.

[0081] The fan 34 draws airflow from the inner cylinder 2 into the air duct 3 and discharges it back into the inner cylinder 2 through the air outlet 32 ​​of the air duct 3, thus achieving airflow circulation. The heat exchange module 33 may include, for example, an evaporator and a condenser, which are arranged sequentially along the air inlet direction. The evaporator is used to cool and liquefy the water vapor in the airflow flowing from the inner cylinder 2 to achieve dehumidification. The condenser is used to heat the airflow, and after reaching the set drying temperature, the airflow flows back into the inner cylinder 2.

[0082] In this embodiment, the air inlet 31 and air outlet 32 ​​of the air duct 3 are both located on the wall surface of the opening of the outer cylinder 1. Specifically, the air inlet 31 is located on the left side of the outer cylinder 1, and the air outlet 32 ​​is located on the right side of the outer cylinder 1, arranged symmetrically with the air inlet 31. This not only allows the airflow to penetrate the entire inner cylinder 2 radially, but also simplifies the structure of the air duct 3, making the arrangement of the air duct 3 more convenient.

[0083] Typically, the air outlet 32 ​​of the air duct 3 does not require a filter, such as Figure 7 As shown, of course, a filter can also be installed at the air outlet 32. In this case, the pore size of the filter can be larger than the pore size of the filter at the air inlet 31.

[0084] See Figure 8 Since the air inlet 31 and air outlet 32 ​​of the air duct 3 are both located at the opening of the outer cylinder 1, that is, outside the opening of the inner cylinder 1, the drying airflow blown out from the air outlet 32 ​​will flow in the annular flow channel between the glass bowl 5 and the outer cylinder 1, and then be sucked in by the air inlet 31. The drying airflow is difficult to enter the inner cylinder 2 to dry the clothes.

[0085] For this purpose, see Figures 9 to 12 In this embodiment, a slope 51 is provided on the side of the glass bowl 5 opposite to the air outlet 32 ​​to refract the drying airflow from the air outlet 32 ​​into the inner drum 2, so as to ensure the drying effect of the clothes.

[0086] Of course, if the glass bowl 5 is itself a hemispherical bowl, there is no need to specially set the inclined surface, because the outer wall of the glass bowl 5 already forms an inclined surface that can refract airflow.

[0087] See Figure 12 In order to maximize the refraction of the drying airflow blown out of the air outlet 32 ​​into the inner cylinder 2, thereby improving the drying effect of the clothes, in this embodiment, the angle A between the inclined surface 51 and the air outlet 32 ​​is 40° to 50°.

[0088] It should be noted that inclined plane 51 is not necessarily a plane; it can also be like... Figure 11 The arc-shaped surface shown above, when it is an arc-shaped surface, the included angle mentioned above is the angle formed by the tangent at each point on the arc and the air outlet direction. That is to say, the included angle A formed by the tangent at each point on the arc and the air outlet direction is 40° to 50°.

[0089] See Figure 11 and Figure 12 The inclined surface 51 is provided with first ribs 52 at intervals along the direction away from the air outlet 32, so that the inclined surface 51 has a wave structure.

[0090] In this way, the wave structure of the inclined surface 51 makes the inclined surface 51 a wave surface with high and low undulations, which can diffuse and refract the drying airflow blown out from the air outlet 32 ​​at various positions, so that the drying airflow is more evenly distributed inside the inner drum 2, making the temperature in the inner drum 2 more uniform, and thus making the clothes more evenly heated, thereby improving the drying efficiency and drying effect.

[0091] Optional, such as Figure 12 As shown, the first rib 52 is a first arc-shaped strip protruding from the inclined surface 51, and the central angle B corresponding to the first arc-shaped strip is 40° to 120°. This design can maximize the diffuse scattering effect of the wave structure, further improve the uniformity of the drying airflow distribution in the inner cylinder 2, and improve the drying efficiency and drying effect.

[0092] See Figures 9 to 12 The glass bowl 5 also has a bowl surface 53 that can come into contact with clothing. Second ribs 54 are spaced apart on the bowl surface 53, so that the bowl surface 53 also has a wave-like structure.

[0093] In this embodiment, the surface 53 of the glass bowl 5 that comes into contact with the clothes is also designed with a wave structure. In this way, the wave structure of the bowl surface 53 can produce a rubbing effect with the clothes during the operation of the inner drum 2, achieving a combination of machine washing and hand washing, resulting in better washing effect of the clothes, and thus achieving the purpose of saving energy, time and efficiency.

[0094] Optional, such as Figure 12 As shown, the second rib 54 is a second arc-shaped strip protruding from the bowl surface 53, and the central angle corresponding to the second arc-shaped strip is 115° to 180°. This design can maximize the rubbing effect of the wave structure and avoid excessive friction between the wave structure and the clothes, thus preventing damage to the garment.

[0095] It should be noted that the length direction of the first rib 52 cannot be parallel to the air outlet direction of the outlet 32; preferably, they are perpendicular to each other. As for the direction of the second rib 54, there is no restriction; it can be the same as or different from the direction of the first rib 52.

[0096] Meanwhile, the number and size of the first rib 52 and the second rib 54 are not limited; that is, their distribution density can be the same or different. In this embodiment, the first rib 52 is arranged more densely than the second rib 54, which can improve the diffuse scattering effect.

[0097] See Figure 6 The water inlet of the outer cylinder 1 is located on the upper left side of the outer cylinder 1. That is, the water inlet of the outer cylinder 1 is adjacent to the air inlet 31 of the air duct 3 and is located above the air inlet 31. In this way, during the water intake process, under the action of water pressure and gravity, the water flows directly onto the filter screen, which plays a preliminary cleaning role.

[0098] The following is combined with Figure 5 and Figure 8 The usage process of the washer-dryer combo in this embodiment will be described.

[0099] Washing Mode: During the water intake process, the filter screen at the air inlet 31 is cleaned for the first time using water pressure and gravity. After water intake is complete, the inner drum 2 begins to rotate at a low speed, and the water flow due to rotational inertia cleans the filter screen for the second time. When the inner drum 2 enters high-speed rotation / spin-drying high-speed rotation, the water flow due to rotational inertia and the whipping / touching friction between the clothes and the filter screen perform a third thorough cleaning. Throughout the entire washing process, the filter screen is cleaned gradually from shallow to deep. At the same time, during the washing process, the clothes rub against the glass bowl 5, achieving a kneading function. Washing and kneading are carried out simultaneously for better results.

[0100] Drying mode: The inner drum 2 rotates, and the clothes and the filter screen are whipped / touched and rubbed to clean the filter screen. The fan 33 starts and brings in hot air and blows it towards the glass bowl 5. The wave structure of the inclined surface 51 produces a diffuse scattering effect on the airflow, and the heat is distributed to all parts of the inner drum 2, making the heating more uniform and improving the drying efficiency and drying effect.

[0101] As can be seen from the above description, the washer-dryer combo of this embodiment can not only clean the filter while washing / drying to achieve thorough self-cleaning of the filter, but also improve drying efficiency and drying effect through the wavy glass bowl. At the same time, the wavy glass bowl can produce a rubbing effect with the clothes during the operation of the inner drum, achieving a combination of machine washing and hand washing, resulting in better washing effect of clothes, and thus achieving the purpose of energy saving, time saving and high efficiency.

[0102] Example 3

[0103] This embodiment only describes the differences from Embodiment 2. Specifically, the angle A between the inclined surface 51 and the air outlet 32 ​​is 40°, the central angle B corresponding to the first arc strip is 40°, and the central angle corresponding to the second arc strip is 115°. This design ensures the diffuse scattering effect of the inclined wave structure while giving the bowl surface wave structure a certain kneading effect.

[0104] Example 4

[0105] This embodiment only describes the differences from Embodiment 2. Specifically, the angle A between the inclined surface 51 and the air outlet 32 ​​is 40°, the central angle B corresponding to the first arc strip is 120°, and the central angle corresponding to the second arc strip is 180°. This design can take into account both the diffuse scattering effect of the inclined wave structure and the kneading effect of the bowl-shaped wave structure.

[0106] Example 5

[0107] This embodiment only describes the differences from Embodiment 2. Specifically, the angle A between the inclined surface 51 and the air outlet 32 ​​is 50°, the central angle B corresponding to the first arc strip is 40°, and the central angle corresponding to the second arc strip is 180°. This design can ensure the diffuse scattering effect of the inclined wave structure while improving the kneading effect of the bowl surface wave structure.

[0108] Example 6

[0109] This embodiment only describes the differences from Embodiment 2. Specifically, the angle A between the inclined surface 51 and the air outlet 32 ​​is 50°, the central angle B corresponding to the first arc strip is 120°, and the central angle corresponding to the second arc strip is 115°. This design can improve the diffuse scattering effect of the inclined wave structure, and the bowl-shaped wave structure also has a certain kneading effect.
