Description

[Technical Field]

[0001] (Cross-citation of related applications) This application claims priority to Chinese Patent Application No. 202111023112.5 filed on September 1, 2021, and No. 202111450553.3 filed on November 30, 2021, the entire contents of which are incorporated herein by reference. The present invention relates to the field of household appliances, and more particularly to a combination washer-dryer machine. [Background technology]

[0002] As people's living standards improve and lifestyles change, basic consumer goods functions alone are no longer enough. In the washing machine industry, fully automatic washer-dryers, which can dry clothes after washing, are gaining popularity among consumers, especially in rainy weather. The drying modules of existing washer-dryers are generally divided into exhaust, condensation, and heat pump types.

[0003] The principle of the exhaust-type drying module is to heat air using a heater in the exhaust assembly, transport the heated air to a drum, remove moisture from the clothes in the drum using the heated air, and finally exhaust the hot and humid air from the device to the outside. This method consumes a lot of energy, is inefficient, is noisy, and the high temperature of the hot air can damage the clothes. Furthermore, an exhaust pipe is required to exhaust the heated air, which not only occupies a large space but also poses a risk of burns to people and the environment.

[0004] The principle of the condensation drying module is that air is heated by a heater in the condensation assembly, and the heated air is blown into the drum, where it removes moisture from the clothes in the drum. The resulting hot and humid air is converted into dry, cool air by condensation in the condenser, and the dry, cool air is then heated by the heater and transported to the drum, circulating in this way to achieve the drying purpose. However, the energy consumption and drying efficiency of condensation drying are highly dependent on the ambient temperature and fluctuate greatly with changes in ambient temperature, and the heating and condensation stages are closely related to the temperature difference. Particularly in areas with low ambient temperatures, this method has the drawback of high energy consumption, low efficiency, and not achieving the desired drying effect.

[0005] The principle of a heat pump drying module is that heated air is transported by a condenser in a heat pump circulation assembly into a drum, where it removes moisture from the clothes in the drum and is sent to an evaporator for dehumidification. The dehumidified air is then reheated by the condenser and transported back to the drum. A temperature control medium is circulated through the heat pump circulation assembly, condensing in the condenser to release heat, and evaporating in the evaporator to absorb heat. This eliminates the need for a heater in the condensation drying module and recovers and utilizes the heat generated during the drying process using the temperature control medium, further reducing energy consumption and maintaining a lower drying temperature than condensation drying, thereby protecting the clothes. However, like condensation drying, the energy consumption and drying efficiency of heat pump drying are highly dependent on ambient temperature and fluctuate significantly with changes in ambient temperature. This is because the heat release effect of the condenser and the heat absorption effect of the evaporator are both closely related to the temperature difference. This is particularly true in areas with low ambient temperatures, where heat pump drying suffers from high energy consumption, low efficiency, and insufficient drying results. Furthermore, the heat pump drying module, especially the heat pump, is expensive, which is a major reason why it is difficult to reduce the price of a heat pump washer-dryer combination machine. Summary of the Invention [Means for solving the problem]

[0006] In order to overcome the above drawbacks, the present invention provides a combined washer-dryer machine including a water inlet, a water outlet, a drum, a drum drive unit, and a drying module, wherein the drum drive unit is communicably connected to the drum to drive the drum to rotate, the water inlet and the water outlet are each connected to the drum, the drying module includes a moisture absorbing and dehumidifying member, a moisture absorbing passage, and a dehumidifying passage, the moisture absorbing passage includes a moisture absorbing passage air inlet and a moisture absorbing passage air outlet, and the drum includes a moisture absorbing passage air inlet and a moisture absorbing passage air outlet. The inlet is connected to the moisture absorption passage air outlet, and a moisture absorption passage fan is provided in the moisture absorption passage to form a moisture absorption flow between the drum and the moisture absorption passage, and a dehumidification passage fan is provided in the dehumidification passage to form a dehumidification flow in the dehumidification passage, and the moisture absorption and dehumidification member is provided on the path between the moisture absorption passage and the dehumidification passage, and both the moisture absorption flow and the dehumidification flow flow through the moisture absorption and dehumidification member, which absorbs moisture in the moisture absorption flow while moving, particularly rotating, and discharges the absorbed moisture through the dehumidification flow. The fan here may be any device that can transport gas, such as a blower, but is not limited to a blower.

[0007] The moisture absorbing and dehumidifying member includes a moisture absorbing runner assembly, a runner housing, and a runner drive mechanism for driving the rotation of the moisture absorbing runner assembly, wherein the moisture absorbing runner assembly is rotatably supported in the runner housing along a rotation axis, and the moisture absorbing runner assembly includes a wheel disc made of a renewable moisture absorbing material, an outer peripheral housing member connected to a peripheral region of the wheel disc so as not to rotate relative to each other, and a central housing member connected to a central region of the wheel disc so as not to rotate relative to each other.

[0008] In some technical solutions, the outer peripheral housing member includes an outer peripheral upper clamp housing and an outer peripheral lower clamp housing, which are fixed to each other when surrounding the outer peripheral surface of the wheel disc and configured to clamp an end face in a peripheral region of the wheel disc. In additional or alternative technical solutions, the center housing member includes a central upper clamp member and a central lower clamp member, which are fixed to each other with at least a portion passing through a central hole of the wheel disc and configured to clamp an end face in a central region of the wheel disc. The fixation of the outer peripheral upper clamp housing and the outer peripheral lower clamp housing and / or the fixation of the central upper clamp member and the central lower clamp member may be achieved by, for example, engagement, threaded fasteners, welding, and / or adhesive bonding. In some technical solutions, the outer peripheral housing member includes end areas extending along a direction perpendicular to the rotation axis and circumferential areas extending along a circumferential direction, and the end areas of the outer peripheral housing member are used to clamp an end face in a peripheral region of the wheel disc. In particular, the outer peripheral upper clamp housing and the outer peripheral lower clamp housing each have a longitudinal cross section similar to an L shape, and each include an end area extending along a direction perpendicular to the rotation axis and a circumferential area extending along a circumferential direction. The end area of ​​the outer peripheral housing member facing the inner bottom surface of the runner housing is configured to at least partially cover a bottom roller mechanism on the inner bottom surface of the runner housing, particularly along the direction of the rotation axis, and the end area of ​​the outer peripheral lower clamp housing is in rolling contact with the bottom roller mechanism.

[0009] In some technical solutions, the central housing member includes an end area extending along a direction perpendicular to the rotation axis and a circumferential area extending along a circumferential direction, and the end area of ​​the central housing member is used to clamp the end face of the wheel disc in the central region. In particular, the central upper clamping member and the central lower clamping member each have an L-shaped longitudinal section, and each include an end area extending along a direction perpendicular to the rotation axis and a circumferential area extending along a circumferential direction.

[0010] In some technical solutions, the moisture-absorbing runner assembly further includes a deformable central end face shock absorbing member, which is arranged to form a cushion between an end face in the central region of the wheel disc and an end face of the end area of ​​the central housing member.

[0011] In some technical solutions, the moisture-absorbing runner assembly further includes a power input member for introducing power from the runner drive mechanism to rotate the moisture-absorbing runner assembly, the power input member being integrally formed with or connected to the surface of the outer peripheral housing member or the surface of the central housing member, and the power input member may be, for example, formed of convex teeth, grooves, or a smooth surface.

[0012] In some technical solutions, the moisture absorption runner assembly further includes an auxiliary rotating ring that is integrally molded or connected to the outer peripheral surface of the outer housing member, aligns with a circumferential roller mechanism arranged on the inner peripheral edge of the runner housing, and is in rolling contact with the circumferential roller mechanism.

[0013] In some technical solutions, the moisture-absorbing runner assembly further includes a deformable outer circumferential shock absorbing member, the outer circumferential shock absorbing member is disposed to form a cushion between the outer circumferential surface of the wheel disc and the inner circumferential surface of the outer circumferential housing member, and the outer circumferential shock absorbing member is preferably bonded to the outer circumferential surface of the wheel disc.

[0014] In some technical solutions, a runner seal is provided on the outer surface of the outer periphery of the moisture-absorbing runner assembly, and a runner housing seal is provided on the inner surface of the runner housing, where the runner seal and the runner housing seal are in relative rotatable contact to form a seal. "In relative rotatable contact" means that the contact between the runner seal and the runner housing seal does not significantly increase the rotational resistance of the moisture-absorbing runner assembly with the runner seal. The "outer surface of the outer periphery of the moisture-absorbing runner assembly" here refers not only to the outer periphery of the moisture-absorbing runner assembly, but also to an end surface of the moisture-absorbing runner assembly that extends perpendicular to the rotation axis of the outer periphery, or to an outer surface of the moisture-absorbing runner assembly that is inclined relative to the rotation axis. The "inner surface of the runner housing" here refers not only to the inner periphery of the runner housing, but also to the inner top or bottom surface of the runner housing. Those skilled in the art will understand that the contact surface between the runner seal and the runner housing seal is necessarily located between the air inlet and air outlet paths of the moisture-absorbing runner assembly to provide a seal.

[0015] In some technical solutions, the runner seal member is formed from the outer surface of the moisture-absorbing runner assembly itself or a surface structure integrally formed thereon, and / or the runner housing seal member is formed from the inner surface of the runner housing itself or a surface structure integrally formed thereon. Additionally or alternatively, the runner seal member and / or the runner housing seal member are formed by a separately manufactured seal, such as a seal strip or soft rubber seal. For example, in one technical solution, the runner seal member is formed by a seal strip fixed to the outer surface of the moisture-absorbing runner assembly, and the runner housing seal member is formed by the inner surface of the runner housing itself. In another technical solution, the runner seal member is formed by the outer surface of the moisture-absorbing runner assembly itself, and the runner housing seal member is formed by a seal strip fixed to the inner surface of the runner housing. In another technical solution, both the runner seal member and the runner housing seal member are formed by seal strips. In some technical solutions, the runner seal member and the runner housing seal member are sealed by relatively rotatable contact with each other via surfaces extending parallel to the rotation axis and / or surfaces extending perpendicular to the rotation axis. For example, in one technical solution, the runner seal member and the runner housing seal member are arranged side by side in the same plane along a direction perpendicular to the rotation axis, and the runner seal member and the runner housing seal member are sealed by relatively rotatable contact with each other via opposing peripheral surfaces. In another technical solution, the runner seal member and the runner housing seal member are arranged in a staggered manner along the rotation axis but are adjacent to each other, and so the runner seal member and the runner housing seal member are sealed by relatively rotatable contact with each other via opposing end surfaces.In some technical solutions, multiple pairs of runner seals and runner housing seals are provided, each pair of which is rotatably contacted and sealed, and each pair of runner seals and runner housing seals is staggered relative to one another to form a long seal. For example, in one technical solution, the multiple pairs of runner seals and runner housing seals are staggered relative to one another along the rotation axis. In another technical solution, at least one pair of runner seals and runner housing seals may be disposed between the end face of the moisture-absorbing runner assembly and the inner top or bottom surface of the runner housing. In some technical solutions, multiple runner seals and / or multiple runner housing seals are provided, and one runner seal is rotatably contacted and sealed with multiple runner housing seals, or one runner housing seal is rotatably contacted and sealed with multiple runner seals. Optionally, the outer circumferential surface of the runner seals forms the maximum diameter of the moisture-absorbing runner assembly. Particularly preferably, the moisture absorption runner assembly includes an outer peripheral upper clamp housing and an outer peripheral lower clamp housing fixed to each other, and the runner seal member is disposed on the outer circumferential side of the mutually fixed position of the outer peripheral upper clamp housing and the outer peripheral lower clamp housing to seal the mutually fixed position.

[0016] In some technical solutions, the power input member, the auxiliary rotating ring and the runner seal member are completely staggered relative to one another along the direction of the rotation axis, in particular adjacent to one another.

[0017] The runner housing includes an upper runner housing and a lower runner housing, which are detachably connected to each other. The lower runner housing may be integrally formed with the lower housing of another functional assembly. A plurality of partition ribs extending within a radial range are integrally molded or fixed to the inner end surface of the runner housing, dividing the internal cavity of the runner housing into at least a moisture-absorbing region and a dehumidifying region, with a gap between the partition ribs and the wheel disc of the moisture-absorbing runner assembly. In some technical solutions, two partition ribs extending within a radial range are integrally molded or fixed to the inner end surface of the lower runner housing of the runner housing, dividing the internal cavity of the runner housing into a moisture-absorbing region and a dehumidifying region. In some technical solutions, at least two sets of partition ribs are molded opposite each other at positions within the inner end surface of the lower runner housing of the runner housing, extending toward each other and spaced apart slightly greater than the axial thickness of the moisture-absorbing runner assembly.

[0018] In another technical solution, at least three partition ribs extending toward each other are integrally molded or fixed to the inner wall of the end surface of the runner housing to divide the internal cavity of the runner housing into at least a moisture absorption region, a dehumidification region, and a cooling region, with the cooling region being disposed between the moisture absorption region and the dehumidification region. Here, the moisture absorption region is fluidly connected to the moisture absorption passage, the dehumidification region is fluidly connected to the dehumidification passage, and the cooling region is fluidly connected to the cooling passage. A cooling passage fan is provided in the cooling passage to transport air from the external environment to the cooling region of the runner housing. Optionally, a branch is led from the dehumidification passage to one cooling passage, and the dehumidification passage fan guides gas to the cooling region of the runner housing. The air outlet of the cooling passage is fluidly connected to an air outlet on the housing of the combined washer-dryer machine or connected to an area downstream of the moisture absorption and dehumidification member in the dehumidification passage.

[0019] In some technical solutions, a partition seal member is fixed to the surface of the partition rib, particularly the partition rib surrounding the dehumidifying region, facing the wheel disc of the moisture-absorbing runner assembly, with a gap of 0 to 5 mm between the partition seal member and the wheel disc in the moisture-absorbing runner assembly. In some technical solutions, a partition seal member strip is fixed to at least a portion of the partition rib, and the partition seal member strip interferes with the wheel disc of the moisture-absorbing runner assembly. In some technical solutions, the size of the partition seal member maintains only a small gap with the wheel disc, not interfering with the rotation of the wheel disc, and minimizing airflow between the moisture-absorbing region, the dehumidifying region, and optionally the cooling region. It is particularly advantageous to set the gap between the partition seal member and the wheel disc to between 0.2 mm and 5 mm, for example, 0.8 mm. This gap prevents the general axial runout of the wheel disc from interfering with the rotation of the wheel disc, while effectively preventing airflow between each region. The partition seal member is preferably flexible to avoid damage to the wheel disc when the axial runout of the wheel disc is abnormally strong. The partition seal member is preferably made of foam, silicone, or soft rubber. In another technical solution, the partition seal member is configured as a seal strip, which can contact the wheel disc in an assembled state to form a relatively rotatable contact seal.

[0020] In some technical solutions, to reduce heat diffusion between the moisture absorption zone, the dehumidification zone, and optionally the cooling zone, a separating and insulating member is further fixed to the surface of the partition rib facing the wheel disc of the moisture absorption runner assembly, and at least a portion of the separating and insulating member is enclosed by the partition seal member, where a portion of the partition seal member is always closer to the wheel disc than the separating and insulating member. In an advantageous technical solution, a recess for accommodating the separating and insulating member is formed on the side of the partition seal member facing the wheel disc, and the thickness of this recess is greater than the thickness of the separating and insulating member so that the partition seal member is closer to the wheel disc. The partition seal member and / or the separating and insulating member have a shape and size that fits the edge of the internal cavity surrounded by the partition rib and, if necessary, the runner housing. The separating and insulating member is preferably made of a thermal insulating material. However, the insulating member may be manufactured using a cheaper metal or alloy, which has good thermal conductivity but produces a certain thermal insulation effect when enclosed by the seal.

[0021] In some technical solutions, a partition pressing sheet is further fixed to the surface of the partition rib facing the wheel disc of the moisture absorption runner assembly, and the partition pressing sheet is configured to position the partition seal member and press it against the partition rib. The partition pressing sheet can have, for example, protrusions for positioning and pressing. Preferably, the partition pressing sheet and the separate insulation member can be configured integrally.

[0022] In some technical solutions, the runner housing is further provided with at least one airflow guide sheet, which is configured to divide the moisture absorption flow entering the runner housing into at least two airflows and direct the at least two airflows through different regions of the wheel disc of the moisture absorption runner assembly. One end of the at least one airflow guide sheet is preferably molded or fixed to the moisture absorption inlet region of the runner housing for the moisture absorption flow, and is preferably evenly arranged in the moisture absorption inlet region. The at least one airflow guide sheet is preferably arranged essentially uniformly throughout the moisture absorption region. The at least one airflow guide sheet is preferably curved. This prevents the moisture absorption flow from concentrating in a radially outer region along with the rotating moisture absorption runner assembly after entering the moisture absorption region, thereby improving the uniformity of the moisture absorption flow passing through the wheel disc and increasing moisture absorption efficiency.

[0023] At least one circumferential roller mechanism is further provided on the inner peripheral edge of the runner housing, the circumferential roller mechanism including a circumferential roller and a circumferential roller holder, the circumferential roller being rotatably supported by the circumferential roller holder, the circumferential roller holder being provided on the inner peripheral edge of the runner housing, wherein when viewed along a direction parallel to the rotation axis, the circumferential roller is arranged within a size range along the direction of the rotation axis of the moisture-absorbing runner assembly, and when viewed along a direction perpendicular to the rotation axis, the circumferential roller is arranged between the moisture-absorbing runner assembly and the runner housing, and the circumferential roller can be in rolling contact with the outer peripheral surface of the moisture-absorbing runner assembly during at least a portion of the rotation process of the moisture-absorbing runner assembly.

[0024] In some technical solutions, in the initial installation position, the circumferential roller mechanism rolls together without pressing the moisture-absorbing runner assembly against each other, so that the circumferential rolling mechanism always assists the rotation of the moisture-absorbing runner assembly without significantly increasing the rotational resistance of the moisture-absorbing runner assembly, preventing the moisture-absorbing runner assembly from wobbling in the radial direction during rotation and ensuring stable rotation.

[0025] In an alternative technical solution, a gap exists between the circumferential roller mechanism and the moisture-absorbing runner assembly in the initial mounting position, and when the moisture-absorbing runner assembly is displaced along a direction perpendicular to the rotation axis, the moisture-absorbing runner assembly can be in rolling contact with the circumferential roller mechanism, which further reduces the rotational resistance of the moisture-absorbing runner assembly during normal rotation and is only effective when the moisture-absorbing runner assembly is wobbling in the radial direction.

[0026] In some technical solutions, the circumferential roller is configured to be flexibly deformable, thereby allowing the deformability of the circumferential roller to be simply utilized to mitigate radial fluctuations of the moisture-absorbing runner assembly. Advantageously, the circumferential roller includes an inner ring, an outer ring, and spokes connecting the inner ring and the outer ring, with at least two spokes being provided and configured to be flexibly deformable. It is also advantageous that the connection formed by the spokes at the connection between the inner ring and the outer ring does not intersect the rotation axis of the roller. Here, the inner ring can be understood as a rotating shaft or a tube fitted to the rotating shaft. In an alternative technical solution, the spokes can be replaced with a flexible material, such as a foam or silicone ring, i.e., a flexible material is provided between the inner ring and the outer ring. For example, a flexible material is fitted to the outside of the inner ring, and then the outer ring is fitted to the outside of the flexible material. Here, the outer ring can be either hard or flexible.

[0027] In a further or alternative technical solution, the circumferential roller holder is configured to be displaceable. In particular, the circumferential roller holder itself is configured to be elastically deformable. Additionally or alternatively, the circumferential roller holder can move as a whole along a sliding track to change its distance from the rotation axis, and an elastic restoring member is fixed to the runner housing to return the circumferential roller holder to its initial position. For example, the sliding track is configured from a recess formed in the runner housing and a slider formed in cooperation with the circumferential roller holder. Alternatively, the sliding track is configured from a guide protrusion formed in the runner housing and a guide engagement claw formed in cooperation with the circumferential roller holder.

[0028] In some technical solutions, a plurality of circumferential roller mechanisms are arranged on the inner peripheral edge of the runner housing, preferably six circumferential roller mechanisms. Particularly advantageously, the inner peripheral edge of the runner housing is configured in a stepped shape, with circumferential roller holders provided on end surfaces of the steps extending in a direction perpendicular to the rotation axis, i.e., along the radial direction, and the circumferential rollers are rotatably supported by the circumferential roller holders. Preferably, the circumferential surfaces of the steps form a runner housing seal member, which contacts and seals with the runner seal member of the moisture-absorbing runner assembly. The plurality of circumferential roller mechanisms are arranged uniformly or non-uniformly on the inner peripheral edge of the runner housing. In particular, when the moisture-absorbing runner assembly is driven by the runner drive mechanism at its outer peripheral edge, the plurality of circumferential roller mechanisms are arranged non-uniformly on the inner peripheral edge of the runner housing, with more circumferential roller mechanisms provided on one side away from the contact point between the runner drive mechanism and the moisture-absorbing runner assembly. For example, when the runner drive mechanism and the moisture absorbent runner assembly interact in the form of gears that mesh, the gear meshing location is the contact location between the runner drive mechanism and the moisture absorbent runner assembly, and in this case, it is advantageous to provide more circumferential roller mechanisms on one side away from the gear meshing location. Also, when the runner drive mechanism and the moisture absorbent runner assembly interact in the form of belts, the location where the belt in the runner drive mechanism and the moisture absorbent runner assembly press against each other on the outer periphery is the contact location between the runner drive mechanism and the moisture absorbent runner assembly, and in this case, it is advantageous to provide more circumferential roller mechanisms on one side away from the pressing location. Because the runner is driven in the circumferential direction, a certain amount of eccentric force is inevitably applied to the runner.

[0029] In some technical solutions, the circumferential rollers at least partially protrude from the inner peripheral wall of the runner housing at the axial height where they are located, and do not need to protrude toward the rotation axis relative to the entire inner peripheral surface of the runner housing. In other technical solutions, the circumferential rollers at least partially protrude toward the rotation axis through the entire inner peripheral wall of the inner peripheral edge of the runner housing, thereby being closer to the rotation axis than the entire inner peripheral surface area of ​​the inner peripheral edge of the runner housing.

[0030] In some technical solutions, the circumferential roller holder is fixed to the runner housing by a fixing mechanism, and the fixing mechanism is configured to be able to adjust the radial distance between the circumferential roller holder and the moisture-absorbing runner assembly at an initial installation position, so that the circumferential roller mechanism can accommodate more sizes of moisture-absorbing runner assemblies and more operation modes.

[0031] At least one bottom roller mechanism is further provided on the inner bottom surface of the runner housing, the bottom roller mechanism including a bottom roller and a bottom roller holder, the bottom roller being rotatably supported by the bottom roller holder, the bottom roller holder being provided on the runner housing, the bottom roller being arranged within a size range along a direction perpendicular to the rotation axis of the moisture-absorbent runner assembly when viewed along a direction parallel to the rotation axis, the bottom roller being arranged between the moisture-absorbent runner assembly and the runner housing when viewed along a direction parallel to the rotation axis, the bottom roller being arranged such that a distance between the bottom roller and the moisture-absorbent runner assembly is smaller than a minimum distance between the moisture-absorbent runner assembly and the runner housing. Preferably, at least a portion of the bottom roller protrudes from the entire inner bottom surface of the runner housing toward the moisture-absorbent runner assembly.

[0032] In some technical solutions, in the initial mounting position, the bottom roller mechanism is in rolling contact with the bottom of the rotating moisture-absorbing runner assembly. In another alternative technical solution, in the initial mounting position, a gap exists between the bottom roller mechanism and the moisture-absorbing runner assembly, and when the moisture-absorbing runner assembly is displaced along the direction of the rotation axis, the moisture-absorbing runner assembly is in rolling contact with the bottom roller mechanism.

[0033] In some technical solutions, the outer peripheral housing member of the moisture-absorbing runner assembly has a pair of end areas extending along a direction perpendicular to the rotation axis, the bottom roller mechanism is arranged on an inner bottom surface of the runner housing in an area opposite to the end area facing the inner bottom surface of the outer peripheral housing member, and the end area can be in rolling contact with the bottom roller mechanism.In another alternative technical solution, the central housing member of the moisture-absorbing runner assembly has a pair of end areas extending along a direction perpendicular to the rotation axis, the pair of end areas clamping an end face in a central region of a wheel disc, and the bottom roller mechanism is arranged on an inner bottom surface of the runner housing in an area opposite to the end area of ​​the central housing member, and the bottom roller mechanism can be in rolling contact with the end area of ​​the central housing member of the moisture-absorbing runner assembly.

[0034] In some technical solutions, a plurality of bottom roller mechanisms, preferably four, are provided on the inner bottom surface of the runner housing, and it is preferable that the plurality of bottom roller mechanisms are uniformly distributed on the same circumference on the inner bottom surface of the runner housing.

[0035] In some technical solutions, the bottom roller mechanism is configured to be non-deformable or slightly deformable.

[0036] In some technical solutions, the peripheral surface of the bottom roller is configured smooth or has a textured surface.

[0037] In some technical solutions, the bottom roller holder is integrally molded or connected to the inner bottom surface of the runner housing, the bottom roller holder is configured as a hollow member, and the assembled bottom roller is partially accommodated in the inner cavity of the hollow member. In particular, a recess for accommodating the bottom roller mechanism is provided on the inner bottom surface of the runner housing, and the bottom roller holder is fixed in the recess, or the bottom roller holder is directly formed as a recess structure on the inner bottom surface of the runner housing.

[0038] In some technical solutions, the bottom roller holder is fixed to the runner housing by a fixing mechanism, and the fixing mechanism is configured to allow the axial spacing between the bottom roller holder and the moisture absorption runner assembly to be adjusted at an initial mounting position.

[0039] The moisture-absorbing runner assembly is driven by the runner drive mechanism at its outer periphery. In other words, the runner drive mechanism drives the rotation of the moisture-absorbing runner assembly at the outer periphery of the power input member of the moisture-absorbing runner assembly. The runner drive mechanism includes a runner drive motor and a corresponding transmission mechanism. The output shaft of the runner drive motor is connected to the corresponding transmission mechanism so as not to rotate relative to the power input member, for example, by keyway engagement. The corresponding transmission mechanism is configured similarly to the power input member of the moisture-absorbing runner assembly.

[0040] In some technical solutions, the power input member has a circumferential edge formed with convex teeth, and the runner drive mechanism engages with the convex teeth to rotate the power input member. The convex teeth are configured as, for example, straight teeth, oblique teeth, curved teeth, or sprocket teeth with a predetermined shape. Correspondingly, the corresponding transmission mechanism of the runner drive mechanism is configured as, for example, a spur gear, a helical gear, a bevel gear, or a sprocket.

[0041] In another alternative technical solution, a groove is formed on the periphery of the power input member, and the runner drive mechanism engages with the groove to drive the rotation of the power input member, and correspondingly, the corresponding transmission mechanism of the runner drive mechanism is configured as an intermeshing belt, for example, a toothed belt pulley.

[0042] In another alternative technical solution, a smooth surface is provided on the periphery of the power input member, and the runner drive mechanism drives the rotation of the power input member by the friction force between the smooth surface and the runner drive mechanism. Correspondingly, the corresponding transmission mechanism of the runner drive mechanism is configured as a friction pulley, for example, a flat belt pulley. Optionally, a micro-surface structure is formed on the smooth surface to increase the friction force.

[0043] In some technical solutions, the runner housing further includes a housing for housing the runner drive mechanism. That is, the runner housing includes housings for housing the moisture-absorbing runner assembly and the runner drive mechanism, respectively, and the runner drive mechanism and the moisture-absorbing runner assembly can share a single runner housing. Advantageously, the housing for the runner drive mechanism in the runner housing is provided with a baffle, and optionally, a sealing member for blocking airflow from the housing for the moisture-absorbing runner assembly to the housing for the runner drive mechanism. In an alternative technical solution, the runner drive mechanism and the moisture-absorbing runner assembly each include independent housings that are fixed to each other. In such a technical solution, an additional seal is required to seal the mutually fixed position of the housings for the runner drive mechanism and the moisture-absorbing runner assembly.

[0044] In some technical solutions, the runner drive mechanism is located entirely or partially outside the radial size range of the moisture absorbing runner assembly.

[0045] The dehumidification passage has a dehumidification passage air inlet and a dehumidification passage air outlet for communicating the dehumidification passage with an external environment, the dehumidification passage air inlet communicating with a housing air inlet on an outer housing in which the washer-dryer combination machine is disposed, and the dehumidification passage air outlet communicating with a housing air outlet on the outer housing in which the washer-dryer combination machine is disposed. A dehumidification passage fan transports air from the external environment to the moisture absorbing and dehumidifying member through the dehumidification passage air inlet and discharges gas flowing through the moisture absorbing and dehumidifying member to the external environment through the dehumidification passage air outlet, thereby forming a dehumidified flow in the dehumidification passage.

[0046] In this technical solution, advantageously, a dehumidifying and condensing assembly is provided in the dehumidifying passage downstream of the moisture absorbing and dehumidifying member, and the dehumidifying and condensing assembly is configured to condense and dehumidify the dehumidified flow passing through the moisture absorbing and dehumidifying member, so that the gas discharged through the housing air outlet on the outer housing of the combined washer-dryer machine has a low temperature and is relatively dry, and does not affect the external environment.

[0047] In such a technical solution, it is further advantageous that a dehumidifying filtering section is provided in the dehumidifying passage upstream of the moisture absorbing and dehumidifying member, particularly at the dehumidifying passage air inlet, to filter impurities in the air from the external environment, thereby protecting the dehumidifying passage and, in particular, protecting the moisture absorbing and dehumidifying member from contamination by impurities.

[0048] In another alternative technical solution, the dehumidification passage is configured as an internal circulation passage that does not communicate with the external environment. In the dehumidification passage, a dehumidifying condensation assembly is disposed downstream of the moisture absorption and dehumidification member to condense and dehumidify the high-temperature, humid gas flowing through the moisture absorption and dehumidification member, and a dehumidification passage fan is disposed upstream or downstream of the moisture absorption and dehumidification member to transport the dry air condensed and dehumidified by the dehumidifying condensation assembly back to the moisture absorption and dehumidification member, forming an internal circulation dehumidification flow within the dehumidification passage. This eliminates the need for a dehumidifying filter unit, an air inlet / outlet on the outer housing of the combined washer-dryer machine, and passages communicating with the air inlet / outlet of the housing, thereby achieving cost and space savings.

[0049] Particularly advantageously, the drying module includes a dehumidifying and heating assembly disposed in the dehumidifying passage. The dehumidifying and heating assembly is configured to heat the dehumidified flow to increase the temperature of the dehumidified flow and improve the regeneration efficiency of the wheel disc. In terms of the flow path of the dehumidified flow, the dehumidifying and heating assembly may be disposed upstream and / or downstream of the moisture absorbing and dehumidifying member. In some technical solutions, the dehumidifying and heating assembly is provided separately from the moisture absorbing and dehumidifying member. In another alternative technical solution, the dehumidifying and heating assembly may be integrally formed with the moisture absorbing and dehumidifying member or may be fixed by a connecting means such as a threaded fastener. Particularly preferably, the housing of the dehumidifying and heating assembly and the runner housing of the moisture absorbing and dehumidifying member have essentially complementary shapes and are connected to each other. The dehumidifying and heating assembly can determine heating power according to the detected value of the temperature sensor.

[0050] When the dehumidifying and heating assembly is integrally molded with or fixed to the moisture absorption and dehumidifying member, the dehumidifying and heating assembly includes a dehumidifying and heating assembly housing and a dehumidifying and heating assembly. The dehumidifying and heating assembly housing has an upper wall, a lower wall, and a side wall connecting the upper wall and the lower wall. In an advantageous technical solution, the dehumidifying and heating assembly housing is configured as a sector-shaped body having a sector-shaped cross section, with a sector-shaped upper wall, a lower wall, a radial side wall extending along a radial direction, and a circumferential side wall extending along a circumferential direction. Particularly advantageously, the sector-shaped body and the runner housing, particularly the runner upper housing in the runner housing, are configured to have complementary shapes. For example, the runner upper housing in the runner housing has a sector-shaped notch, and this notch is essentially the same shape as the sector-shaped body. It is preferable that the radius of the sector-shaped body is essentially equal to the radius of the runner housing. Dehumidification outlets are formed in the end walls of the upper and lower walls facing the dehumidification runner assembly, and airflow flows into the dehumidification runner assembly through the dehumidification outlets. The dehumidification outlets are preferably configured as large as possible to maximize airflow efficiency. One or more dehumidification inlets are formed in the side walls. When the dehumidification inlets are arranged in the circumferential side walls of the sector, the dehumidification airflow can enter the dehumidification heating assembly via the shortest route. When the dehumidification inlets are arranged in the radial side walls of the sector, the dehumidification airflow flows more uniformly in the radial direction through the dehumidification runner assembly. In particular, when multiple dehumidifying inlets are arranged on two radial side walls of the fan body or on two radial side walls and one circumferential side wall of the fan body, the dehumidifying flow flows more uniformly through the dehumidifying runner assembly within the cross-sectional range of the fan body, thereby improving the regeneration efficiency of the dehumidifying runner assembly.

[0051] The dehumidifying and heating assembly housing can be manufactured integrally with the runner housing, but more preferably, the dehumidifying and heating assembly housing is manufactured separately from the runner housing and fixed to the runner housing. In an advantageous technical solution, a preferably flexible connecting seal member is provided between the dehumidifying and heating assembly housing manufactured separately from the runner housing and the runner housing, particularly the runner upper housing, to prevent the dehumidifying flow from escaping through a gap between the dehumidifying and heating assembly housing and the runner housing. Preferably, a connecting heat insulating member is further provided between the dehumidifying and heating assembly housing and the runner housing to diffuse heat to the outside, particularly reducing diffusion in the moisture-absorbing region of the runner housing, and the connecting heat insulating member is at least partially covered by the connecting seal. More preferably, the entire connecting heat insulating member is covered by the connecting seal, and both the dehumidifying and heating assembly housing and the runner housing are in contact only with the connecting seal, thereby improving the sealing effect. Preferably, the connecting seal and / or the connecting heat insulating member have an inner edge that matches the shape of the dehumidifying flow outlet in the dehumidifying and heating assembly housing. The connection seal is preferably made of foam, silicone, or soft rubber. The connection insulation member is preferably made of a heat-insulating material. However, it is also conceivable to manufacture the connection insulation member using a cheaper metal or alloy, which has good heat conductivity but can still provide a certain heat insulation effect even when covered with the connection seal.

[0052] The dehumidifying and heating assembly in the dehumidifying and heating assembly is preferably configured as a heating tube or PTC heating element extending in one plane. Advantageously, the heating tube is configured in a bellows or wave shape. Particularly advantageously, the area enclosed by the envelope of the dehumidifying and heating assembly occupies at least 70% of the cross section of the dehumidifying outlet, and / or the cross section of the dehumidifying and heating assembly occupies no more than 40% of the cross section of the dehumidifying outlet.

[0053] In some technical solutions, the dehumidifying heating assembly further includes a mesh panel. The mesh panel has a shape that matches the dehumidifying outlet and can be fixed to the dehumidifying outlet. A plurality of through holes are formed in the mesh panel, and the plurality of through holes are distributed as uniformly as possible on the mesh panel. Advantageously, the plurality of through holes are distributed in a bellows or wave pattern on the mesh panel. Particularly advantageously, the opening sizes of the plurality of through holes gradually decrease or have a decreasing tendency along the flow direction of the dehumidifying flow, with the through holes closer to the dehumidifying inlet having larger openings and the through holes further away from the dehumidifying inlet having smaller openings, thereby further improving the uniformity of the dehumidifying flow through the moisture absorption runner assembly.

[0054] In some technical solutions, the dehumidifying and heating assemblies are fixed to the downstream side of the mesh panel along the flow direction of the dehumidifying flow, particularly to the downstream end face of the mesh panel. Particularly advantageously, the dehumidifying and heating assemblies are configured to correspond to the shape of the through-holes in the mesh panel and are arranged in a staggered manner from the through-holes. Particularly advantageously, the dehumidifying and heating assemblies are arranged in a staggered manner from the through-holes in the inflow direction of the dehumidifying flow, so that the dehumidifying flow passes through the through-holes and then heads toward the dehumidifying and heating assemblies, thereby improving heating efficiency.

[0055] In some technical solutions, the dehumidifying and heating assembly further includes a thermostat mounting portion. The thermostat mounting portion is used to detect the temperature in the internal cavity of the dehumidifying and heating assembly. A controller of the combined washer-dryer machine controls the dehumidifying and heating assembly based on the temperature detected by the thermostat. Because the heated dehumidifying airflow is prone to turbulence (or vortexes) in the internal cavity of the dehumidifying and heating assembly, the internal cavity temperature obtained directly from the internal cavity space is likely to be highly unstable or fluctuate. To obtain as stable an internal cavity temperature as possible, the thermostat mounting portion includes a thermally conductive sheet and a thermostat. It is particularly preferred that the thermally conductive sheet at least partially covers the thermostat. Conducting the temperature from the thermally conductive sheet to the thermostat allows for detection of a more stable and representative internal cavity temperature than directly detecting the internal cavity temperature using gas in the internal cavity, and is particularly advantageous for temperature control of the dehumidifying and heating assembly. In an advantageous technical solution, the thermostat mounting part is arranged on the end wall in which the opening is located, and is arranged outside the opening.

[0056] The dehumidifying condensation assembly includes a dehumidifying condensation assembly housing, a dehumidifying condensation tube assembly, and a dehumidifying condensation outlet pipe, the dehumidifying condensation tube assembly being fixed to the middle of the dehumidifying condensation assembly housing and configured to condense and dehumidify the dehumidified water flowing through the dehumidifying condensation tube assembly. Condensed water is discharged from the dehumidifying condensation outlet pipe. A baffle is provided between the dehumidifying condensation tube assembly and the dehumidifying condensation assembly housing to prevent the dehumidified water from bypassing the dehumidifying condensation tube assembly after entering the dehumidifying condensation assembly housing and flowing directly to the outlet of the dehumidifying condensation assembly housing through a gap between the dehumidifying condensation assembly housing and the dehumidifying condensation assembly housing.

[0057] The drying module further includes a moisture absorption heating assembly disposed along the moisture absorption passage. The moisture absorption heating assembly is configured to heat the moisture absorption flow to increase its temperature and improve drying efficiency. The moisture absorption heating assembly is particularly advantageously disposed near the moisture absorption passage air outlet of the drying module, allowing the drying air to be heated by the moisture absorption heating assembly and preventing evaporated moisture from condensing on the inner wall of the moisture absorption passage. The moisture absorption heating assembly can determine whether to apply heating and the heating power based on the detected value of the temperature sensor.

[0058] In some technical solutions, the drying module includes a moisture absorbing condensing assembly disposed in the moisture absorbing passageway, the moisture absorbing condensing assembly configured to additionally condense and dehumidify the moisture absorbing flow. Particularly advantageously, the moisture absorbing condensing assembly is disposed near the moisture absorbing passageway air inlet of the drying module to pre-dehumidify the hot, humid air from the drum, thereby improving drying efficiency.

[0059] In some technical solutions, a moisture absorbing filter is provided in the moisture absorption passage upstream of the moisture absorbing and dehumidifying member, particularly at the moisture absorption passage air inlet, to filter impurities in the moisture absorption flow and protect the moisture absorption passage, particularly the moisture absorbing and dehumidifying member, from contamination by impurities.

[0060] In some technical solutions, the drying module is modularly configured. In some technical solutions, the drying module is composed of multiple functional modules that are individually assembled and fixed to the drum housing and / or the frame of the combined washer-dryer. Preferably, the moisture absorbing and dehumidifying member is fixed to the frame of the combined washer-dryer without contacting the drum, ensuring that vibrations during drum operation do not affect the stable operation of the moisture absorbing and dehumidifying member. The above technical solutions have the advantages of making full use of the internal space within the housing of the combined washer-dryer and allowing more flexibility in the external design of each functional module.

[0061] In another alternative preferred technical solution, the drying module is pre-assembled as a single pre-assembled module, particularly prior to the complete assembly of the combined washer-dryer machine. The pre-assembled module includes a single, integrated modular lower housing and multiple separate upper housings, the modular lower housing and upper housing forming multiple chambers, each configured to accommodate one or more functional assemblies, such as a moisture absorption runner assembly, a moisture absorption passage fan, a dehumidification passage fan, a runner drive mechanism, a moisture absorption heating assembly, a moisture absorption condensation assembly, a dehumidification heating assembly, and a dehumidification condensation assembly. This integrated modular manufacturing significantly simplifies assembly and improves assembly efficiency, while eliminating or shortening the need for corresponding connecting ducts, resulting in a more compact structure of the drying module.

[0062] In some technical solutions, multiple lugs, preferably four, are integrally molded or fixed to the periphery of the upper and / or lower housing of the drying module. The lugs are overlappingly fixed to the frame of the combined washer-dryer machine, particularly to fixing portions on the inner wall surface of the frame or to side edges, preferably at least three side edges, more preferably four side edges, of the frame, to secure the drying module to the frame of the combined washer-dryer machine. The overlapping fixation can be achieved by threaded fasteners, welding, and / or engagement. Particularly advantageously, when the drying module has only one integral lower housing, multiple lugs, preferably four, are integrally molded or fixed to the periphery of the lower housing. It should be noted that the drying module does not contact the drum in the assembled state. This prevents the functional modules in the drying module from being further affected by drum vibration, which is highly advantageous for drying modules based on the moisture absorbing and dehumidifying member proposed in the present invention. Vibration can prevent the wheel discs in the moisture absorbing runner assembly from rotating stably and collide with the runner housing or an assembly fixed to the runner housing, which can further cause seal failure and lead to airflow escaping from the intended flow path.

[0063] In some technical solutions, the drying module can be arranged above, behind or below the drum, in particular it is advantageous to arrange the drying module above the drum, since the drum is a horizontally arranged cylinder, leaving more space above its sides to arrange the functional assemblies in the drying module, and arranging the drying module above the drum makes assembly and maintenance easier.

[0064] To minimize the height or thickness of the combined washer-dryer machine, the present invention provides a more preferred technical solution, in which the rotation axes of the moisture absorption runner assembly and the moisture absorption passage fan are not flush with but perpendicular to the rotation axis of the drum, and are distributed on both sides of the rotation axis of the drum. Particularly advantageously, the moisture absorption runner assembly, moisture absorption passage fan, dehumidification passage fan, runner drive mechanism, and optionally the moisture absorption condensation assembly, dehumidification condensation assembly, and dehumidification heating assembly in the drying module are arranged side by side and essentially on the same plane, i.e., at least partially overlapping but not completely offset, along the direction of the rotation axis of the moisture absorption runner assembly. This minimizes the height or thickness of the entire drying module.

[0065] Particularly advantageously, the air outlet of the moisture absorption passage fan is fluidly connected to the internal cavity of the runner housing through a moisture absorption inlet formed in the circumferential side wall of the runner housing, and the air outlet of the moisture absorption passage fan is directly connected to the moisture absorption inlet of the runner housing or indirectly connected via an air outlet connection. Preferably, the moisture absorption inlet is disposed in the circumferential side wall of the runner housing between the moisture absorption runner assembly and the bottom of the runner housing, and may of course be disposed between the moisture absorption runner assembly and the top of the runner housing. Particularly preferably, the air outlet of the moisture absorption passage fan is configured to open along a direction perpendicular to the rotation axis of the moisture absorption runner assembly.

[0066] Also, particularly advantageously, the air outlet of the dehumidifying passage fan is fluidly connected to the internal cavity of the runner housing through a dehumidifying inlet formed in a circumferential side wall of the runner housing, and the air outlet of the dehumidifying passage fan is directly connected to the dehumidifying inlet of the runner housing or indirectly connected via an air outlet connection. Preferably, the dehumidifying inlet is disposed in the circumferential side wall of the runner housing between the moisture-absorbing runner assembly and the top of the runner housing, and may also be disposed between the moisture-absorbing runner assembly and the bottom of the runner housing. Particularly preferably, the air outlet of the dehumidifying passage fan is configured to open along a direction perpendicular to the rotation axis of the moisture-absorbing runner assembly.

[0067] In an alternative technical solution, the air outlet of the dehumidifying passage fan is directly or indirectly connected to a dehumidifying inlet on the dehumidifying and heating assembly housing via an air outlet connection, and the dehumidifying and heating assembly housing is integrally molded or fixed to the runner housing. The dehumidifying and heating assembly housing has one or more dehumidifying inlets, which may be arranged on a side wall of the dehumidifying and heating assembly housing, where the side wall refers to a housing wall to which an end wall extending perpendicular to the rotation axis of the moisture-absorbing runner assembly is connected at an angle. In particular, when the dehumidifying and heating assembly housing is configured as a sector having a sector-shaped cross section, the dehumidifying inlet may be formed on a circumferential side wall and / or a radial side wall extending along the radial direction of the sector. Particularly preferably, the air outlet of the dehumidifying passage fan is configured to open along a direction perpendicular to the rotation axis of the moisture-absorbing runner assembly.

[0068] In an alternative technical solution, the moisture-absorbing runner assembly is fixed to the runner housing and does not rotate relative to the runner housing. The runner housing is not divided into different sections. The moisture-absorbing runner assembly and the moisture-absorbing passage alternately communicate with the dehumidifying passage. Specifically, when the drying module is operating, the moisture-absorbing runner assembly first communicates with the moisture-absorbing passage to absorb and dry the clothes in the drum. Then, for example, when it is determined based on information from a sensor connected to the moisture-absorbing runner assembly that the wheel disc in the moisture-absorbing runner assembly is saturated, the switching structure communicates the moisture-absorbing runner assembly with the dehumidifying passage to regenerate the wheel disc of the moisture-absorbing runner assembly. This technical solution can reduce costs by eliminating the need for a runner drive mechanism for rotating the wheel disc, dynamic seals (e.g., the runner seal member and runner housing seal member for forming the dynamic seal), and rotation auxiliary members (e.g., the circumferential roller mechanism, bottom roller mechanism, auxiliary rotating ring, etc.).

[0069] The moisture absorption runner assembly is fixed to the runner housing, and the runner housing is also assumed to be divided into at least two regions, and the two regions are alternately connected to the moisture absorption passage and the dehumidification passage. In some technical solutions, a duct rack that swings back and forth is provided on the outer periphery of the runner housing, and flexible ducts are connected between the duct rack and the moisture absorption passage and the dehumidification passage, respectively. When the duct rack swings back and forth, duct openings on the duct rack communicate with the inlets and outlets of the at least two regions, respectively.

[0070] The combined washer-dryer machine further includes an air outlet duct, a detergent dispenser box, and a pipe assembly disposed between the air outlet of the drum and the air inlet of the drying module for directing airflow from the drum to the drying module.

[0071] The pipe assembly includes an inlet pipe, a first outlet pipe, a second outlet pipe, and a third outlet pipe, one end of the inlet pipe is connected to a water pipe, the other end of the inlet pipe is connected to one end of the first outlet pipe, one end of the second outlet pipe, and one end of the third outlet pipe, respectively, the other end of the first outlet pipe is connected to the water inlet of the condenser in the combined washer-dryer machine, the other end of the second outlet pipe is connected to the water inlet of the detergent dispenser box, and the other end of the third outlet pipe is connected to the water inlet of the air outlet duct. In some technical solutions, the condenser, detergent dispenser box, water inlet of the air outlet duct, and pipe assembly are arranged on the top of the drum. The water inlets and pipe assemblies of the condenser, detergent dispenser box, and air outlet duct are preferably located at at least three corners of the combined washer-dryer machine. In some technical solutions, solenoid valves are provided on the inlet pipe, the first outlet pipe, the second outlet pipe, and / or the third outlet pipe to control the on / off and / or flow rate of the water pipes. In some embodiments, the pipe assembly and the solenoid valve form an integrated structure. In some technical solutions, the inlet pipe is connected to a water pipe via a hose, and / or the first outlet pipe is connected to the water inlet of the condenser via a hose, and / or the second outlet pipe is connected to the water inlet of the detergent dispenser box via a hose, and / or the third outlet pipe is connected to the water inlet of the air outlet duct via a hose. In some technical solutions, the inlet pipe is provided with a filter for filtering water flowing through the inlet pipe. In some technical solutions, the water outlet of the detergent dispenser box is connected to the water inlet of the drum, and the water outlet of the drum is connected to a drain pipe. In some technical solutions, a filtering mesh and an injection mechanism for injecting the filtering mesh are provided in the air outlet duct, the air outlet duct has a first water inlet for directing water to the injection mechanism, and a third outlet pipe is connected to the first water inlet. In some technical solutions, the air outlet duct has a second water inlet for directing cooling water to a cooling passage, which is configured to direct cooling water to the outer wall of the air outlet duct to cool it, and a third outlet pipe is connected to the second water inlet. Providing a combined water system with one inlet and multiple outlets meets multiple water supply requirements to optimize drying effect and better protect the drying module assembly, and can more fully meet the needs of a combined washer-dryer machine.

[0072] The air outlet duct structure is configured to guide airflow from the drum to the drying module. The air outlet duct extends from bottom to top along the outer surface of the rear wall of the drum. The air outlet duct is provided on the left rear or right rear of the drum. Extending the air outlet duct from bottom to top along the outer surface of the rear wall of the drum reduces the overall height of the combined washer-dryer machine compared to when the air outlet duct extends along the outer surface of the upper wall of the drum, leaving more space above the drum for arranging the components of the drying module. The air outlet duct is preferably flexibly connected to the air inlet of the drying module.

[0073] It is particularly advantageous to provide a filter module in the air outlet duct, which includes a filter mesh for filtering the airflow through the air outlet duct. The use of the filter mesh in the air outlet duct can prevent foreign matter such as lint contained in the airflow from entering the drying module, reducing the dehumidifying and heating effects and affecting the drying effect. In some technical solutions, the filter mesh is disposed obliquely in the air outlet duct. The angle between the filter mesh and the longitudinal axis of the air outlet duct is, for example, between 15° and 45°. Preferably, the filter mesh spans the entire cross section of the air outlet duct and filters all airflow passing through the air outlet duct. In some technical solutions, the filter mesh is detachably disposed in the air outlet duct, and an opening for attaching and removing the filter mesh is formed in the air outlet duct at a position corresponding to the filter mesh. In some technical solutions, the air outlet duct is curved, and an inlet is provided at a first end of the air outlet duct for connecting to the outlet of the drum, and an outlet is provided at a second end of the air outlet duct for connecting to the inlet of the drying module. In some technical solutions, the air outlet duct includes first and second half housings for defining a cavity, and the filter mesh is disposed obliquely in the cavity and filters all airflow passing from the first end to the second end of the air outlet duct. In some technical solutions, the filter mesh extends from the bottom of the second half-housing to the edge of a support plate provided on the top of the first half-housing and extending into the cavity, and the filter mesh covers at least 90%, preferably at least 95%, of the cross section of the cavity, and a mounting portion is provided on the support plate for sealingly mounting a water supply device of the filter mesh self-cleaning device. In some technical solutions, the support plate is arc-shaped, with one end attached to the top plate of the first half-housing and the other end extending into the cavity to secure the filter mesh. In some technical solutions, the support plate has a flat shape, is molded integrally with the first half-housing, and extends into the cavity. In some technical solutions, the first half-housing and the second half-housing each have an arc-shaped area starting from a first end and a linear area connected to the arc-shaped area, and the arc-shaped areas of the first half-housing and the second half-housing each gradually widen from the first end to the linear areas of the first half-housing and the second half-housing.

[0074] The filtration module further includes a filter mesh self-cleaning device for cleaning the filter mesh. In some technical solutions, the filter mesh self-cleaning device is provided at an end of the air outlet duct remote from the drum. In some technical solutions, the filter mesh self-cleaning device includes a fluid supply pipe and a nozzle connected to the fluid supply pipe, the nozzle configured to distribute cleaning fluid to the inlet surface of the filter mesh. In some technical solutions, the interconnected fluid supply pipe and the nozzle form a Venturi tube shape. In some technical solutions, a flat opening is formed at the free end of the nozzle. In some technical solutions, the width of the flat opening is at least 90% of the width of the filter mesh, preferably the same width. In some technical solutions, the angle between the nozzle and the filter mesh is between 0° and 45°. In some technical solutions, multiple passages are formed within the nozzle so that the cleaning fluid is distributed in the direction of the width of the flat opening. In some technical solutions, the filter mesh self-cleaning device further includes a vibration mechanism for vibrating the filter mesh, a spray mechanism for spraying the filter mesh, and / or a scraping mechanism for scraping the filter mesh. In some technical solutions, the fluid supply pipe extends along the inner surface of the air outlet duct to a middle portion of the filtering mesh. In some technical solutions, the fluid supply pipe extends along the length of the inner surface of the air outlet duct and is fixed to the inner surface, and the nozzles are multiple rotatable nozzles connected to the fluid supply pipe at intervals to inject fluid onto the inlet surface of the filtering mesh. In some technical solutions, a pressurizing structure is provided within the fluid supply pipe. In some technical solutions, the inlet pipe extends along the entire length of the inner wall of the air outlet duct, and the nozzles are multiple auto-rotating nozzles connected to the inlet pipe at intervals to inject water onto the inlet surface of the filtering mesh. In some technical solutions, the filtering mesh self-cleaning device and the inlet of the air outlet duct are located at opposite ends of the filtering mesh, and the water outlet of the filtering mesh self-cleaning device and the inlet of the air outlet duct are located on the same side of the filtering mesh. In some technical solutions, the water inlet of the filter mesh self-cleaning device is connected to the tap water inlet pipe of the combined washer-dryer machine via a guide pipe. In some technical solutions, the water inlet of the filter mesh self-cleaning device is directly connected to the adjacent tap water inlet pipe via an adapter. In some technical solutions, the air outlet duct is located on one side of the drum away from the tap water inlet pipe, and a guide pipe connecting the filter mesh self-cleaning device water inlet and the tap water inlet pipe runs across the drum. In some technical solutions, the air outlet duct, the tap water inlet pipe, and the adapter therebetween are located on substantially the same side of the drum. In some technical solutions, the filter mesh self-cleaning device includes a spray mechanism for spraying the filter mesh, a vibration mechanism for vibrating the filter mesh, a spray mechanism for spraying the filter mesh, and / or a scraping mechanism for scraping the filter mesh. The spray mechanism is configured to spray a water flow toward the actual filtering surface of the filter mesh. In some technical solutions, the filter mesh is detachably installed in the air outlet duct. Preferably, the filtering mesh is disposed obliquely within the linear areas of the first and second half-housings. Preferably, the filtering mesh is flexible and extends obliquely from the arcuate area of ​​the first half-housing to the edge of a support plate extending into the cavity in the linear area of ​​the second half-housing.

[0075] In another alternative technical solution, the filtration mesh can be manually cleaned. In some technical solutions, the air outlet duct includes a first area connected to the drum, a second area connected to the drying module, and a filtration mesh arrangement area connecting the first and second areas, and directs airflow from the drum to the drying module, where the filtration mesh arrangement area can be accessed from outside the housing of the combined washer-dryer machine for operation. In some technical solutions, a first closable opening for accessing the filtration mesh arrangement area is provided in the front panel, side panel, or rear panel of the combined washer-dryer machine. In some technical solutions, at least one filtration mesh is mounted in a filter cassette, which is removably and sealingly attached to the filtration mesh arrangement area and fluidly connected to the first and second areas to form the air outlet duct. In some technical solutions, the filter cassette is flexible and attached to the filtration mesh arrangement area with an interference fit. In some technical solutions, the filter cassette is rigid and attached to the filtration mesh arrangement area with a snap fit. In some technical solutions, the filtration mesh arrangement area includes a second closable opening for opening and closing the filtration mesh arrangement area. In some technical solutions, at least one filtration mesh is removably or fixedly attached directly within the filtration mesh arrangement area, or at least one filtration mesh is attached within a filter cassette, and the filter cassette is removably and sealingly attached to the filtration mesh arrangement area.

In some technical solutions, at least one filtration mesh is arranged obliquely in the filtration mesh arrangement area.In some technical solutions, at least one filtration mesh is arranged in the filtration mesh arrangement area perpendicular to the longitudinal axis of the filtration mesh arrangement area.

[0076] The combined washer-dryer machine further includes a cooling passage for cooling the airflow flowing through the air outlet duct. In some embodiments, an outer pipe is fitted to the outside of the air outlet duct, and the cooling passage is formed between the outer wall of the air outlet duct and the inner wall of the outer pipe. In some embodiments, a housing for at least a portion of the air outlet duct has a double-layered wall, and the cooling passage is formed between the two layers. In some embodiments, the cooling passage covers at least a portion of the air outlet duct. In some embodiments, the cooling passage has a first water inlet for guiding cooling water to the cooling passage and a first drain port for discharging the cooling water. In some embodiments, a water injection nozzle connected to the first water inlet is further provided, and the water injection nozzle is configured to inject cooling water onto the outer wall of the air outlet duct. In some embodiments, the cooling passage is a spiral passage provided in the outer wall of the air outlet duct. In some embodiments, thin ribs are provided on the outer surface of the cooling passage, and the airflow from the blower flows toward the thin ribs. In some embodiments, the air outlet duct is provided with a temperature sensor and / or a humidity sensor for detecting the temperature and / or humidity of the airflow flowing through the air outlet duct.

[0077] The combined washer-dryer machine proposed by the present invention may further include a controller. The controller can start a washing and / or drying program in response to a user's operation of a display and operating device provided on the outer housing of the combined washer-dryer machine. Advantageously, a temperature sensor and / or humidity sensor for detecting the temperature and / or humidity inside the drum is provided inside the drum. Also advantageously, one or more temperature sensors are provided in the moisture absorption passage and / or regeneration passage. Particularly advantageously, the regeneration heating assembly is provided with a thermostat mounting portion, which includes a thermally conductive sheet and a thermostat covered with the thermally conductive sheet. Also advantageously, temperature sensors are provided upstream and downstream of the regeneration condensation assembly. The controller can control the power of the moisture absorption heating assembly and / or the dehumidification heating assembly based on the detection data of the sensors. Here, particularly advantageously, the controller controls the power of the moisture absorption heating assembly and / or the dehumidification heating assembly based on the detection data of the sensors to operate the wheel disc of the moisture absorption runner assembly within an appropriate temperature range, thereby preventing deterioration of moisture absorption performance due to high wheel disc temperatures.

[0078] The combined washer-dryer machine further includes at least two drums for accommodating laundry, the drying module, and optionally a filtration module, each drum including an air inlet passage and an air outlet passage. The drying module selectively dries the laundry in the drum. Preferably, the moisture absorption channel air inlet is selectively fluidly connected to the air outlet passage of the drum, and the moisture absorption channel air outlet is fluidly connected to a corresponding air inlet passage of the drum.

[0079] In some technical solutions, the drying module is selectively fluidly connected to one of the drums by a switching mechanism. The switching structure includes at least a first switching mechanism and a second switching mechanism, and the air inlet passage of the drum is connected to the moisture absorption passage air outlet by the first switching mechanism, and the air outlet passage of the drum is connected to the moisture absorption passage air inlet by the second switching mechanism. In any technical solution, the filtration module is provided between the second switching mechanism and the moisture absorption and dehumidification member. In any technical solution, the second switching mechanism is provided at the connection between the moisture absorption passage air inlet and the air outlet passage of the drum. In any technical solution, the number of second switching mechanisms is one or more, and each is provided in the air outlet passage of the drum. In any technical solution, the number of filtration modules is one or more, and each is provided in the air outlet passage of the drum, located upstream or downstream of the second switching mechanism. According to the above technical solution, multiple drums share the same drying module, thereby simplifying the structure and reducing the size and cost of the device.

[0080] The combined washer-dryer proposed by the present invention has many advantages over less common exhaust-type washer-dryer machines, including lower energy consumption, higher efficiency, quieter noise, and a lower drying temperature. Compared to common condensation-type and heat-pump-type washer-dryer machines, the combined washer-dryer proposed by the present invention uses a moisture-absorbing and dehumidifying element to absorb moisture from the drum, eliminating the need for expensive assemblies such as heat pumps and significantly reducing costs. At the same time, because this moisture-absorbing and dehumidifying element operates primarily based on the moisture-absorbing and dehumidifying properties of its material and / or structure rather than temperature differences, the drying module's sensitivity to environmental temperature is significantly reduced, improving environmental adaptability. In other words, the combined washer-dryer proposed by the present invention can maintain relatively stable energy consumption and drying efficiency in various temperature environments. Furthermore, the technical solution proposed by the present invention further reduces the drying temperature, allowing more types of clothing to be dried without damaging them. The drying module is also a key point of the present invention, and has the same or similar advantages as the combined washer-dryer machine according to the present invention, since it includes a single feature or a combination of features related to the above.

[0081] In order to facilitate understanding of the present invention, the following description will discuss an embodiment of a combined washer-dryer machine proposed by the present invention with reference to the drawings. Note that the present invention can be embodied in various other combinations of the above features and is not limited to the illustrated and described embodiment.

[Figure 19] FIG. 10 is a perspective view showing a third embodiment of a combined washer-dryer according to the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0083] 1 and 2 show a first embodiment of a combined washer-dryer machine according to the present invention from the front and back, respectively. For clarity, FIGS. 1 and 2 omit a portion of the outer housing and some components of the combined washer-dryer machine. In this embodiment, the combined washer-dryer machine W includes a drum R for accommodating laundry, a drum drive unit RD for driving the rotation of the drum R, a drying module D for drying the interior cavity of the drum, a filtration module F for filtering airflow entering the drying module D, an air outlet duct L1 for connecting the air outlet of the drum R to the air inlet of the drying module D, an inlet duct L2 for connecting the air inlet of the drum R to the air outlet of the drying module D, a pipe assembly P for water inlet and outlet, a detergent dispenser box C for dispensing detergent, a frame B for supporting each functional module, and a water inlet and water outlet communicating with the drum R.

[0084] The combined washer-dryer W further includes components that realize the washing and drying functions of the combined washer-dryer, such as an outer housing having at least a clothes pick and a detergent dispenser, a door for closing the clothes pick and a display and operating device disposed on the outer housing, a controller, and a drain pipe. Specifically, the controller initiates the washing and / or drying program of the combined washer-dryer W after receiving a command input by the user via the display and operating device. During the washing program, water flows into the drum R through the water inlet, and the inner cylinder of the drum R rotates under the drive of the drum drive unit RD, using centrifugal force to wash and, if necessary, shake off the laundry inside the drum R. Dirty water is discharged from the drum to the outside of the combined washer-dryer through the water outlet. During the drying program, a circulating airflow is formed through the drum R, the drying module D, and the filtration module F. Moist gas flows from the drum R through the filtration module F into the drying module D, and after drying, it is returned to the drum R. This circulation completes the drying of the interior cavity of the drum R, particularly the laundry therein.

[0085] 3 shows a drying module D in a first embodiment of a combined washer-dryer machine according to the present invention. The drying module D includes a moisture absorbing and dehumidifying member D1, a moisture absorbing passage D2, and a dehumidifying passage D3. The moisture absorbing and dehumidifying member D1 includes a moisture absorbing runner assembly D11, a runner housing D12, and a runner drive mechanism D13. The moisture absorbing passage D2 is provided with a moisture absorbing passage air inlet D21, a moisture absorbing passage air outlet D22, and a moisture absorbing passage fan D23. The dehumidifying passage D3 is provided with a dehumidifying passage fan D33, a dehumidifying heating assembly D34, and a dehumidifying condensing assembly D35. A moisture absorbing heating assembly, a moisture absorbing condensing assembly, and / or a moisture absorbing filtering assembly may be optionally provided within the moisture absorbing passage D2, and a dehumidifying filtering assembly may be optionally provided within the dehumidifying passage D3.

[0086] As shown in FIG. 3, the functional modules are connected to each other and overlappingly attached to the four edges of the top of the frame B of the combined washer-dryer machine by at least four lugs B1, as can be seen more clearly in FIG. 1. At least three of the four lugs B1 are manufactured separately and then attached to the edges of the functional modules, and at least one lug B1 is directly and integrally molded with the runner housing D12 of the moisture absorbing and dehumidifying member D1. Other numbers of lugs B1 and other types of connection to the frame B are also possible. That is, fixing the integrally connected functional modules directly to the frame using the lugs B1 facilitates assembly while reducing the impact of drum vibration on the drying module D. It is also conceivable to fix these functional modules to the frame and the drum, respectively, although fixing the moisture absorbing and dehumidifying member to the frame is particularly advantageous.

[0087] 3, the rotation axes of the moisture absorption runner assembly D11 and moisture absorption passage fan D23, which occupy a large space, are not flush with the rotation axis of the drum R but are substantially perpendicular thereto, and are distributed on both sides of the rotation axis of the drum R. Particularly advantageously, these functional modules, in particular the moisture absorption runner assembly D11, runner drive mechanism D13, moisture absorption passage fan D23, dehumidification passage fan D33, dehumidification heating assembly D34, and dehumidification condensing assembly D35, are arranged side by side essentially on the same plane along the radial direction, i.e., these functional modules at least partially overlap each other along the direction of the rotation axis of the moisture absorption runner assembly D11 so as not to be completely offset from each other.

[0088] In this embodiment, the moisture absorption passage air inlet D21 of the moisture absorption passage D2 is fluidly connected to the air outlet of the drum R, and the moisture absorption passage air outlet D22 of the moisture absorption passage D2 is fluidly connected to the air inlet of the drum R. As shown in Fig. 3, the air outlet of the moisture absorption passage fan D23 is configured to open along a direction perpendicular to the rotation axis of the moisture absorption runner assembly D11, and the air outlet is fluidly connected to the moisture absorption inlet in the circumferential side wall of the runner housing D12 via an air outlet connection, thereby fluidly connected to the moisture absorption region D1211 of the runner housing D12. The moisture absorption inlet in the runner housing D12 is disposed in the circumferential side wall of the runner housing D12 between the moisture absorption runner assembly D11 and the bottom of the runner housing D12.

[0089] As shown in Fig. 3, the dehumidifying passage D3 is configured from end to end as an internal circulation passage that does not communicate with the external environment. The air outlet of the dehumidifying passage fan D33 is similarly configured to open along a direction perpendicular to the rotation axis of the moisture absorption runner assembly D11, and the air outlet is fluidly connected to the circumferential side wall D3413 of the dehumidifying heating housing D341 of the dehumidifying heating assembly D34 via an air outlet connection. The dehumidifying heating assembly D34 is fixed to the upper surface of the runner upper housing D12U of the runner housing D12 and is configured to have a complementary shape thereto. A dehumidifying outlet is formed in the lower wall D3412 of the dehumidifying heating assembly housing D341 and is fluidly connected to the dehumidifying region D1212 of the absorbent runner assembly D11. This results in a drying module D that is compact in structure, particularly in the direction of the rotation axis, which is very advantageous in reducing the height or thickness of the combined washer-dryer machine.

[0090] FIG. 4 shows the flow path of the moisture absorption airflow in the first embodiment of the combined washer-dryer machine according to the present invention, indicated by arrows. When the moisture absorption passage fan D23 is operating, air circulates through the drum R, the drying module D, and optionally the filtration module F, forming a moisture absorption airflow. The moisture absorption passage fan D23 draws moist air from the drum R through the filtration module F into the moisture absorption passage air inlet D21 of the drying module D, where it passes through itself and is discharged into the moisture absorption region located between the bottom of the moisture absorption runner assembly D11 and the runner housing D12. The moist air passes from bottom to top through the wheel disc D111 in the moisture absorption runner assembly D11, becoming dry gas. The dry gas is then introduced back into the drum R via the moisture absorption passage air outlet D22. This circulation dries the interior cavity of the drum R.

[0091] FIG. 5 shows the dehumidification flow path in the first embodiment of the combined washer-dryer machine according to the present invention, indicated by arrows. When the dehumidification passage fan D33 is operated, air circulates within the dehumidification passage, forming a dehumidification flow. The dehumidification passage fan D33 draws in dry gas from the dehumidification condenser assembly D35 and transports it to the dehumidification heating assembly D34. The heated, dry, high-temperature gas enters the dehumidification zone D212 and flows from top to bottom through the wheel disc D111 of the moisture-absorbing runner assembly D11. The dry, high-temperature gas carries moisture from the wheel disc D111 and becomes high-temperature, humid gas. The high-temperature, humid gas is transported to the dehumidification condenser assembly D34, located downstream of the moisture-absorbing runner assembly D11, where it is condensed and dehumidified to become dry, low-temperature gas. The dry, low-temperature gas is then transported back to the moisture-absorbing runner assembly D11. This circulation regenerates the wheel disc D111 of the moisture-absorbing runner assembly D11, thereby continuously maintaining its moisture-absorbing capacity. 4 and 5 are merely examples of the airflow in the moisture absorption passage and the dehumidification passage, and in practice, the airflow may cross the wheel disc D111 from top to bottom in the moisture absorption passage, and the airflow may cross the wheel disc D111 from bottom to top in the dehumidification passage, or may cross the wheel disc D111 from top to bottom or bottom to top at the same time. The present disclosure is not limited thereto.

[0092] FIG. 6 is an exploded view of a moisture absorbing and dehumidifying member D1 in a first embodiment of a combined washer-dryer machine according to the present invention. FIG. 7 is a perspective view of a moisture absorbing runner assembly D11 and a runner lower housing D12L in the first embodiment of the combined washer-dryer machine according to the present invention. As shown in FIGS. 6 and 7, the moisture absorbing and dehumidifying member D1 includes a moisture absorbing runner assembly D11, a runner housing D12, and a runner drive mechanism D13. The runner housing D12 includes a runner upper housing D12U and a runner lower housing D12L, which are fixed to each other to form an internal cavity. The moisture absorbing runner assembly D11 is rotatably supported in the internal cavity of the runner housing D12 along its rotation axis and rotates under the drive of the runner drive mechanism D13. The moisture absorbing runner assembly D11 is driven by the runner drive mechanism D13 at its outer periphery, i.e., the runner drive mechanism D13 applies its output drive force to the outer periphery of the moisture absorbing runner assembly D11. Here, the outer circumferential surface of the moisture-absorbing runner assembly D11 is formed with straight teeth uniformly distributed along the circumferential direction, and the runner drive mechanism D13 includes a corresponding transmission mechanism D132 configured as a spur gear. The moisture-absorbing runner assembly D11 and the runner drive mechanism D13, particularly the corresponding transmission mechanism D132 therein, are essentially arranged side by side along a direction perpendicular to the rotation axis of the moisture-absorbing runner assembly D11, i.e., along the radial direction. The runner housing D12 includes accommodation portions for accommodating the moisture-absorbing runner assembly D11 and the runner drive mechanism D13, respectively, i.e., they share a single runner housing D12.

[0093] 6 and 7, the runner housing D12 is provided with at least two pairs of partition ribs D121 extending opposite to each other on the inner end walls of its runner upper housing D12U and runner lower housing D12L, dividing the internal space of the runner housing D12 into a moisture absorption region D1211 and a dehumidification region D1212, thereby separating the moisture absorption flow and the dehumidification flow inside the runner housing D12. A gap is provided between the partition rib D121 and the wheel disc 111.

[0094] As shown in Figures 6 and 7, a partition seal member D125 is fixed to the surface of the partition rib D121 surrounding the dehumidifying region D1212, facing the wheel disc D111. The size of the partition seal member D125 is designed to maintain a small gap with the wheel disc D111, thereby preventing airflow between the moisture absorption region D1211 and the dehumidifying region D1212 as much as possible without interfering with the rotation of the wheel disc D111. It is particularly advantageous to set the gap between the partition seal member D125 and the wheel disc D111 to between 0.2 mm and 5 mm, for example, 0.8 mm. This gap effectively prevents airflow between the regions without interfering with the rotation of the wheel disc, taking into account the general axial runout of the wheel disc. The partition seal member D125 is flexible, for example, made of foam, silicone, or soft rubber, which helps reduce the risk of damage to the wheel disc if the axial runout of the wheel disc is abnormally strong. In some other alternative technical solutions, the partition seal member is configured as a sealing strip, which contacts the wheel disc in an assembled state and is in relatively rotatable contact with the wheel disc to form a seal.

[0095] 6 and 7, a partition pressing sheet D126 is fixed to the surface of the partition rib D121 surrounding the dehumidifying region D1212, facing the wheel disc D111, and the partition pressing sheet D126 has a plurality of spaced protrusions for positioning and pressing the partition seal member D125 against the partition rib D121. Specifically, a recess for locating the partition pressing sheet D126 is formed on one side of the partition seal member D125 facing the wheel disc D111, and the thickness of the recess is greater than the thickness of the partition pressing sheet D126, so that the partition seal member D125 is adjacent to the wheel disc D111 in an assembled state. The partition seal member D125 and the partition pressing sheet D126 have a shape and size that match at least a portion of the edge of the dehumidifying region D1212. The partition pressure sheet serves to separate the heat insulating members and reduce heat diffusion between the moisture absorption area D1211 and the dehumidification area D1212. Preferably, the partition pressure sheet D126 is made of a heat insulating material, but it can also be made of a cheaper metal or alloy. Here, the metal or alloy has good heat conductivity but still provides a certain heat insulating effect after being covered with a seal.

[0096] As shown in FIGS. 6 and 7, the runner housing D12 further includes an airflow guide sheet D127. The airflow guide sheet D127 divides the moisture-absorbing flow entering the runner housing into two airflows, which then flow from different regions toward the wheel disc D111 of the moisture-absorbing runner assembly D11. One end of the airflow guide sheet D127 is positioned at the center of the moisture-absorbing inlet area of ​​the runner housing D12 for the moisture-absorbing flow. It is conceivable to provide multiple airflow guide sheets, with their ends preferably evenly dividing the moisture-absorbing inlet area and essentially uniformly distributed throughout the moisture-absorbing region. The airflow guide sheet D127 is curved. This airflow guide sheet D127 prevents the moisture-absorbing flow from concentrating in the radially outer region of the rotating moisture-absorbing runner assembly D11 after entering the moisture-absorbing region D1211, thereby improving the uniformity of the moisture-absorbing flow through the wheel disc and improving moisture absorption efficiency.

[0097] As shown in Figures 6 and 7, multiple circumferential roller mechanisms D122 are provided on the inner periphery of the runner housing D12. Each circumferential roller mechanism D122 includes circumferential rollers and circumferential roller holders. The circumferential rollers are rotatably supported by the circumferential roller holders, which are provided on the inner periphery of the runner housing D12. When viewed parallel to the rotation axis of the moisture-absorbing runner assembly D11, i.e., from the axial direction, the circumferential rollers are arranged within the axial size range of the moisture-absorbing runner assembly D11. When viewed perpendicular to the rotation axis of the moisture-absorbing runner assembly D11, i.e., from the radial direction, the circumferential rollers are arranged between the moisture-absorbing runner assembly D11 and the runner housing D12. The circumferential rollers D1221 are in rolling contact with the outer circumferential surface of the moisture-absorbing runner assembly D11 during at least a portion of the rotation of the moisture-absorbing runner assembly D11. In this embodiment, at least a portion of the circumferential rollers protrude from the entire inner circumferential wall of the inner periphery of the runner housing toward the rotation axis. This means that even if the moisture-absorbing runner assembly D11 is shifted in the radial direction, the moisture-absorbing runner assembly D11 will not come into direct contact with the runner housing D12 itself, reducing the risk of damage to the moisture-absorbing runner assembly D11.

[0098] As shown in Figures 6 and 7, a plurality of bottom roller mechanisms D123 are provided on the inner bottom wall of the runner housing D12. Each bottom roller mechanism D123 includes a bottom roller and a bottom roller holder. The bottom roller is rotatably supported by the bottom roller holder, and the bottom roller holder is provided in the runner housing D12. When viewed along a direction perpendicular to the rotation axis of the moisture-absorbing runner assembly D11, i.e., from a radial direction, the bottom rollers are arranged within the radial size range of the moisture-absorbing runner assembly D11. When viewed along a direction parallel to the rotation axis of the moisture-absorbing runner assembly D11, i.e., from an axial direction, the bottom rollers are arranged between the moisture-absorbing runner assembly D11 and the runner housing D12, and the distance between the bottom rollers D1231 and the moisture-absorbing runner assembly D11 is smaller than the minimum distance between the moisture-absorbing runner assembly D11 and the runner housing D12. In the illustrated embodiment, at least a portion of the bottom roller D1231 protrudes from the entire inner bottom wall of the runner housing D12 toward the moisture-absorbing runner assembly D11. This means that even if the moisture-absorbing runner assembly D11 is displaced along the axial direction, the moisture-absorbing runner assembly D11 will not come into contact with the runner housing D12 itself, reducing the risk of damage to the moisture-absorbing runner assembly D11.

[0099] 8 is an exploded view showing a moisture-absorbing runner assembly D11 in a first embodiment of a combined washer-dryer machine according to the present invention. In this embodiment, the moisture-absorbing runner assembly D11 includes a wheel disc D111, an outer peripheral housing member D112, a central housing member D113, a power input member D114, an auxiliary rotating ring D115, a runner seal member D116, an outer peripheral shock absorbing member D117, and a central shock absorbing member D118.

[0100] The wheel disc D111 is made of a renewable moisture-absorbing material. Preferably, the wheel disc D111 is made of a porous structure or a porous material. In some technical solutions, the wheel disc D111 is made of a fiber such as cotton that has a high moisture absorption capacity. The wheel disc D111 has a central hole that is symmetrically arranged along the center of the rotation axis, and the central hole is a through hole.

[0101] As shown in FIG. 8, the outer peripheral housing member D112 is composed of an outer peripheral upper clamp housing D112U and an outer peripheral lower clamp housing D112L, each having a ring-shaped structure. The outer peripheral upper clamp housing D112U has an L-shaped cross section and includes an end area extending along the radial direction and a circumferential area extending along the axial direction. Similarly, the outer peripheral lower clamp housing D112L also has an L-shaped cross section and includes an end area extending along the radial direction and a circumferential area extending along the axial direction. The outer peripheral upper clamp housing D112U and the outer peripheral lower clamp housing D112L are engaged with each other by clips and slots provided thereon, and a recess open on only one side is formed inside the outer peripheral housing D112 to form the peripheral region of the wheel disc D111. In an engaged state, the outer peripheral upper clamp housing D112U and the outer peripheral lower clamp housing D112L cover the entire outer peripheral surface of the wheel disc D111 and clamp the upper and lower end surfaces of the peripheral region of the wheel disc D111, respectively, thereby connecting the outer peripheral housing member D112 and the wheel disc D111 so that they cannot rotate relative to each other. The upper and lower end surfaces of the wheel disc D111 refer to surfaces extending along the radial direction of the wheel disc D111. This makes it very easy to connect the outer peripheral housing member and the wheel disc so that they cannot rotate relative to each other. In some alternative technical solutions, the outer peripheral housing member is composed of two annular housing members having L-shaped longitudinal sections and one circumferential annular housing member, and these two annular housing members having L-shaped longitudinal sections are fixedly connected to the circumferential annular housing member, respectively. Other housing structure types in which recesses opening on only one side are formed on the inside may also be envisioned. In some alternative technical solutions, the end areas of the outer peripheral upper clamp housing and the outer peripheral lower clamp housing may be discontinuous in the circumferential direction as long as they function to clamp the wheel disc. Also, the fixing between the housing members, for example, the fixing between the outer peripheral upper clamp housing D112U and the outer peripheral lower clamp housing D112L in this embodiment, may be realized by methods such as threaded fasteners, welding, adhesives, etc.The installation of the outer peripheral housing member prevents deformation of the wheel disc due to centrifugal force during rotation, particularly deformation of the peripheral area of ​​the wheel disc after moisture absorption, and prevents damage to the wheel disc due to direct collision with the runner housing due to factors such as vibration. In addition, the outer peripheral housing member itself reduces the radial distance between the moisture absorption runner assembly and the runner housing, reducing the amount of air that does not pass through the moisture absorption runner assembly and improving moisture absorption efficiency.

[0102] Furthermore, since the outer peripheral lower clamp housing D112L is configured to be in rolling contact with the bottom roller mechanism D123, and particularly to be in contact already in the initial assembly state, it can constantly provide support force to the moisture-absorbing runner assembly D11 rotated by the bottom roller mechanism D123, and essentially eliminate loss due to sliding friction between the moisture-absorbing runner assembly D11 and the bottom of the runner housing D12. Specifically, when viewed from the axial direction, at least a portion of the end area of ​​the outer peripheral lower clamp housing D112L covers the mounting position of the bottom roller mechanism D123 on the runner lower housing D12L, and therefore the end area of ​​the outer peripheral lower clamp housing D112L is in rolling contact with the bottom roller mechanism D123.

[0103] As shown in FIG. 8, the central housing member D113 is composed of an annular central upper clamping member D113U and a central lower clamping member D113L. The central upper clamping member D113U has an L-shaped cross section and includes radially extending end areas and an axially extending circumferential area. Similarly, the central lower clamping member D113L also has an L-shaped cross section and includes radially extending end areas and an axially extending circumferential area. The central upper clamping member D113U and the central lower clamping member D113L pass through a central hole of the wheel disc D111 and engage with each other via a clip and slot formed thereon, forming a recess on the outside that is open on only one side and accommodates the central region of the wheel disc D111. It is also possible for only the central upper clamping member D113U or the central lower clamping member D113L to pass through the central hole of the wheel disc D111. In the engaged state, the central upper clamp member D113U and the central lower clamp member D113L clamp the wheel disc D111 from the upper and lower end surfaces of the central region thereof, respectively, thereby connecting the central housing member D113 and the wheel disc D111 so that they cannot rotate relative to each other. This makes it very easy to connect the outer peripheral housing member and the wheel disc so that they cannot rotate relative to each other. In some alternative technical solutions, the central housing member is composed of two annular housing members having an L-shaped longitudinal section and one circumferential annular housing member structure, and these two annular housing members having an L-shaped longitudinal section are fixedly connected to the circumferential annular housing member, respectively. Other housing structure types in which recesses that are open on only one side to the outside are formed may also be envisioned. In other alternative technical solutions, the end areas of the central upper clamp housing and the central lower clamp housing are discontinuous in the circumferential direction, provided that they function to clamp the wheel disc. Furthermore, the fastening between the housing members, for example the fastening between the central upper clamping member D113U and the central lower clamping member D113L in this embodiment, may be achieved by threaded fasteners, welding, adhesive or the like.The provision of the central housing member can prevent the relatively fragile wheel disc from colliding with and being damaged by components located on the rotation axis, such as the shaft, and can enhance the holding effect of the wheel disc to avoid undesired deformation.

[0104] As shown in FIG. 8, a power input member D114 is provided on the outer circumferential surface of the outer peripheral upper clamp housing D112U. The power input member D114 may be integrally formed with the outer peripheral upper clamp housing D112U, or may be manufactured separately and then fixed, for example, welded, to the outer circumferential surface of the outer peripheral upper clamp housing D112U. The power input member D114 is configured with straight teeth uniformly distributed along the circumferential direction. Correspondingly, as shown in FIG. 6, the runner drive mechanism D13 includes an output gear that meshes with the power input member D114. Of course, in an alternative technical solution, the power input member may be provided on the outer circumferential surface of the outer peripheral lower clamp housing. Here, it is also possible for the power input member and the runner drive mechanism to be of other gear meshing transmission types, such as a worm gear transmission type or a bevel gear transmission type, or belt transmission types, such as a friction belt transmission type or a meshing belt transmission type, or a chain transmission type. Correspondingly, the power input member is configured as helical teeth for gear transmission, curved teeth, a smooth surface for friction belt transmission, various grooves for meshing belt transmission, or sprocket teeth for chain transmission. Providing the power input member on the outer peripheral surface of the outer housing member contributes to reducing the thickness of the moisture absorbing and dehumidifying member along the rotation axis, and contributes to reducing the height or thickness of the entire combined washer-dryer machine. In other alternative technical solutions, the power input member is provided on the inner peripheral surface of the central housing member, and a runner drive mechanism is correspondingly provided in the central hole of the wheel disc.

[0105] As shown in Fig. 8, an auxiliary rotating ring D115 is further provided on the outer circumferential surface of the outer circumferential upper clamp housing D112U. The auxiliary rotating ring D115 is arranged in a staggered pattern with respect to the power input member D114 in the direction of the rotation axis. The auxiliary rotating ring D115 may be integrally molded with the outer circumferential upper clamp housing D112U, or may be manufactured separately and then fixed, for example, welded, to the outer circumferential surface of the outer circumferential upper clamp housing D112U. As shown in Fig. 6, the auxiliary rotating ring D115 is arranged to coincide with the circumferential roller position of the circumferential roller mechanism D122, particularly, to roll in conjunction with the circumferential rollers in the circumferential rolling mechanism D122. In some technical solutions, in the initial assembly state, the auxiliary rotating ring D115 and the circumferential rollers in the circumferential roller mechanism D122 remain in contact without significant pressure, and when the moisture-absorbing runner assembly D11 starts to rotate, the auxiliary rotating ring D115 comes into rolling contact with the circumferential rollers in the circumferential roller mechanism D122, thereby suppressing radial wobble of the moisture-absorbing runner assembly D11 and ensuring stable operation of the moisture-absorbing runner assembly D11 with almost no increase in rotational resistance of the moisture-absorbing runner assembly D11. Of course, it is also conceivable that in the initial assembly state, a small gap may be left between the auxiliary rotating ring D115 and the circumferential rollers in the circumferential roller mechanism D122 to further reduce rotational resistance and only take effect when the moisture-absorbing runner assembly D11 starts to wobble in the radial direction. Here, it is particularly advantageous to provide the circumferential roller mechanism D122 to be deformable, and in particular to provide the rollers in the circumferential roller mechanism D122 as flexible, thereby reducing the risk of damage when the auxiliary rotating ring D115 collides with the circumferential roller mechanism D122.

[0106] 8, a runner seal member D116 is provided on the outer peripheral surfaces of the outer peripheral upper clamp housing D112U and the outer peripheral lower clamp housing D112L at the position where they are fixed to each other, and the radially inner side of the runner seal member D116 covers the position where the outer peripheral upper clamp housing D112U and the outer peripheral lower clamp housing D112L are fixed to each other, thereby sealing the position where the outer peripheral upper clamp housing D112U and the outer peripheral lower clamp housing D112L are fixed to each other on the radially inner side of the runner seal member D116, thereby preventing airflow that has entered the moisture absorption runner assembly D11 from escaping through the mounting gap between the outer peripheral housing members. In addition, the runner seal member D116 can extend outward in a direction perpendicular to the rotation axis, i.e., in the radial direction, until it comes into contact with a runner housing seal member D124 on the inner peripheral surface of the runner housing D12 so as to be rotatable relative to the runner housing D12. "Relatively rotatably contact" means that the contact between the runner seal member D116 and the runner housing seal member D124 does not significantly increase the rotational resistance of the moisture-absorbing runner assembly D11 with the runner seal member D116. In the illustrated embodiment, the runner housing seal member D124 is formed by the inner peripheral surface of the runner housing D12 itself. In the illustrated embodiment, the outer peripheral surface of the runner seal member D116 forms the maximum diameter of the entire moisture-absorbing runner assembly D11. This allows the radial outer side of the runner seal member D116 to seal the radial gap between the moisture-absorbing runner assembly D11 and the runner housing D12, preventing unabsorbed airflow from flowing through the gap into the drum R. That is, the runner seal member D116 in this embodiment has the dual function of preventing airflow that has entered the moisture-absorbing runner assembly D11 from escaping through the mounting gap between the outer peripheral housing members and preventing unabsorbed airflow from flowing beyond the moisture-absorbing runner assembly D11 and around its periphery, thereby significantly improving moisture absorption efficiency. In some technical solutions, the inner peripheral surface of the runner housing can protrude slightly radially inward to function as a runner housing seal member that contacts and seals with the runner seal member, thereby reducing the radial size of the runner seal member.In this way, i.e., by ensuring that the outer peripheral surface of the runner seal member is not positioned at the maximum diameter of the entire moisture-absorbing runner assembly, the rotating contact seal described above can also be achieved.

[0107] In other technical solutions, a single seal ring is connected (e.g., glued) to the inner circumferential surface of the runner housing at a position coinciding with the runner seal member, thereby functioning as a runner housing seal member that contacts and seals with the runner seal member, and is made of, for example, the same material as the runner seal member. This contributes to reducing the radial size of the runner seal member, allowing for flexible adjustment to the radial size of the runner seal member and providing more design space for arranging the runner seal member on the outer circumferential surface of the outer circumferential housing member. In this way, i.e., by ensuring that the outer circumferential surface of the runner seal member is not positioned at the maximum diameter of the entire moisture-absorbing runner assembly, the above-described rotating contact seal can also be achieved. Furthermore, such a single seal ring protects the runner housing from wear on the inner circumferential surface and can be easily replaced. It is also envisioned that multiple runner seal members can be arranged in a staggered pattern at different positions on the outer circumferential surface of the outer circumferential housing member to at least achieve the above-described dual function, or to achieve the dual function redundantly. For example, one runner seal member is provided on the outer peripheral surface at the position where the outer peripheral upper clamp housing and the outer peripheral lower clamp housing are fixed to each other, and another runner seal member is provided on an outer peripheral surface different from the fixed position of the outer peripheral upper clamp housing or the outer peripheral lower clamp housing, or two other runner seal members are provided redundantly on outer peripheral surfaces different from the fixed positions of the outer peripheral upper clamp housing and the outer peripheral lower clamp housing, respectively.

[0108] As shown in Figure 8, the power input member D114, auxiliary rotating ring D115, and runner seal member D116 are disposed in order from top to bottom along the rotation axis, completely offset from one another on the outer peripheral surface of the outer housing member D112. The power input member D114, auxiliary rotating ring D115, and runner seal member D116 are disposed in a staggered pattern along the rotation axis in a different order.

[0109] As shown in FIG. 8, the moisture-absorbing runner assembly D11 further includes a deformable outer shock absorbing member D117 and a central shock absorbing member D118. The outer shock absorbing member D117 is disposed between the outer peripheral surface of the wheel disc D111 and the inner peripheral surface of the outer housing member D112, and uses its deformability to form a cushion therebetween. In some technical solutions, the outer shock absorbing member D117 is bonded to the outer peripheral surface of the wheel disc D111. The central shock absorbing member D118 is disposed between the end area of ​​the central housing member D113L and the central region of the wheel disc D111, and uses its deformability to form a cushion therebetween. In the illustrated embodiment, the central shock absorbing member D118 is disposed between the end area of ​​the central lower clamp member D113L and the end face of the central region of the wheel disc D111. In alternative technical solutions, the central shock absorbing member D118 may be provided between the end area of ​​the central upper clamp member D113U and the end face of the central region of the wheel disc D111, or one central shock absorbing member D118 may be provided at each of these two locations. In some technical solutions, the central shock absorbing member D118 is bonded to the end face of the central region of the wheel disc D111. The peripheral shock absorbing member D117 and the central shock absorbing member D118 are formed, for example, from foam. Of course, the peripheral shock absorbing member D117 and the central shock absorbing member D118 may also be made of other elastically deformable materials. During the operation of the combined washer-dryer machine, the drum vibrates, which can cause the entire machine to vibrate. When the moisture absorption runner assembly D11 also vibrates, the peripheral shock absorbing member D117 and the central shock absorbing member D118 can buffer the vibrations in the axial and radial directions, protecting the usually fragile wheel disc D111 from damage.

[0110] FIG. 9 is a perspective view showing a dehumidifying and heating assembly D34 in a first embodiment of a combined washer-dryer machine according to the present invention. The dehumidifying and heating assembly D34 includes a dehumidifying and heating assembly housing D341, a mesh panel D342, a dehumidifying and heating assembly D343, and a thermostat mounting portion D344. The dehumidifying and heating assembly housing D341 is configured as a sector-shaped body having a sector-shaped cross section, with a sector-shaped upper wall D3411, a sector-shaped lower wall D3412, a circumferential side wall D3413 connecting the upper wall D3411 and the lower wall D341, and a radial side wall D3414 extending in the radial direction. The sector-shaped body is configured in a shape complementary to the runner upper housing D12U of the runner housing D12. Specifically, a sector-shaped notch is formed in the runner upper housing D12U, and the notch has essentially the same shape as the sector-shaped body of the dehumidifying and heating assembly housing D341. A dehumidification outlet is formed in the lower wall D3412 as large as possible so that airflow can flow from the dehumidification outlet into the dehumidification runner assembly D11. The dehumidification outlet occupies at least 80%, preferably 90%, of the area of ​​the lower wall D3412. A dehumidification inlet is formed in the circumferential side wall D3413 of the dehumidification and heating assembly housing D341 as large as possible. The dehumidification inlet occupies at least 80%, preferably 90%, of the area of ​​the circumferential side wall D3413. This allows the dehumidification flow to enter the dehumidification and heating assembly D34 via the shortest path. When the dehumidification inlet is located in a radial side wall, the dehumidification flow flows more uniformly radially through the dehumidification runner assembly. In particular, when multiple dehumidification inlets are located on two radial side walls or two radial side walls and one circumferential side wall, the dehumidification flow flows more uniformly through the dehumidification runner assembly within the cross-sectional area of ​​the fan-shaped body, improving the regeneration efficiency of the dehumidification runner assembly.

[0111] FIG. 10 is a front perspective view of the mesh panel D342 in the dehumidifying / heating assembly D34 in the first embodiment of the combined washer / dryer according to the present invention. The mesh panel D342 is shaped to fit the dehumidifying outlet and is fixed to the dehumidifying outlet. A plurality of through-holes are formed in the mesh panel D342, and these through-holes are distributed as uniformly as possible across the mesh panel D342. The through-holes are distributed in a bellows-like pattern across the mesh panel D342. Advantageously, the openings of these through-holes gradually decrease in size along the direction of dehumidifying flow, with the openings of the through-holes closest to the dehumidifying inlet becoming larger and those further from the dehumidifying inlet becoming smaller. That is, the openings of these through-holes are configured to gradually decrease in size radially inward. This further improves the uniformity of the dehumidifying flow through the moisture absorption runner assembly.

[0112] FIG. 11 is a rear perspective view of the dehumidifying and heating assembly D34 in the first embodiment of the combined washer-dryer machine according to the present invention. A dehumidifying and heating assembly D343 is provided downstream of the mesh panel D342 along the direction of dehumidifying airflow, i.e., on the rear surface of the mesh panel D342. The dehumidifying and heating assembly D343 is configured as a heating tube that expands in a bellows-like manner within a single plane. The dehumidifying and heating assembly D343 may also be configured using a PTC heater, which may be, for example, a ceramic heating device and an aluminum tube. The dehumidifying and heating assembly D343 is configured to correspond to the shape of the through-holes in the mesh panel D342 and is arranged in a staggered pattern with respect to the through-holes. Specifically, the dehumidifying and heating assembly D343 is arranged in a staggered pattern with respect to the through-holes in the direction of the inflow of the dehumidifying airflow so that the dehumidifying airflow passes through the through-holes and flows toward the dehumidifying and heating assembly D343, thereby improving heating efficiency. The area enclosed by the envelope of the dehumidifying heating assembly D343 occupies at least 70% of the cross section of the dehumidifying outlet, and the cross section of the dehumidifying heating assembly D343 itself occupies a maximum of 40% of the cross section of the dehumidifying outlet, thereby enabling heat to be provided within a sufficiently wide range without interfering with the airflow.

[0113] As shown in Figure 11, the dehumidifying and heating assembly D34 further includes a thermostat mounting portion D344. The thermostat mounting portion D344 is also disposed on the rear surface of the mesh panel, on one side of the area where the through-holes are provided. The thermostat mounting portion D344 is configured to detect the temperature in the internal cavity of the dehumidifying and heating assembly D34. The controller of the combined washer-dryer machine controls the dehumidifying and heating assembly D34 based on the detected temperature. Because the heated dehumidifying airflow is prone to turbulence or turbulence in the internal cavity of the dehumidifying and heating assembly D34, the internal cavity temperature directly obtained in the internal cavity space is highly unstable or prone to fluctuations. In order to obtain the most stable possible internal cavity temperature, the thermostat mounting part D344 includes a thermally conductive sheet D3441 and a thermostat D3442. The thermally conductive sheet D3441 completely covers the thermostat D3442. Rather than detecting the internal cavity temperature directly through the gas in the internal cavity, conducting the temperature from the thermally conductive sheet D3441 to the thermostat D3442 makes it possible to detect a more stable and representative internal cavity temperature, which is particularly advantageous for temperature control of the dehumidifying heating assembly.

[0114] 12 is a perspective view showing the runner upper housing D12U without the dehumidifying and heating assembly D34 attached in the first embodiment of the combined washer-dryer machine according to the present invention. The dehumidifying and heating assembly housing D341 is manufactured separately from the runner housing D12 and fixed onto the runner upper housing D12U. A flexible connection seal D3415 is provided between the dehumidifying and heating assembly housing D341 and the runner upper housing D12U to prevent dehumidification flow from leaking through the gap between the dehumidifying and heating assembly housing D341 and the runner upper housing D12U. A connection insulating member D3416 is further provided between the dehumidifying and heating assembly housing D341 and the runner upper housing D12U to reduce heat diffusion from the dehumidifying and heating assembly housing D341 to the outside, particularly to the moisture-absorbing region D1212 of the runner housing D12. A portion of the connection insulating member D3416 is covered by the connection seal D3415. It is also possible to envision a case where the entire connecting insulation member is covered with a connecting seal, and the dehumidifying and heating assembly housing and the runner upper housing only come into contact with the connecting seal to enhance the sealing effect. The connecting seal D3415 and connecting insulation member D3416 have inner edges that essentially match the shape of the dehumidifying outlet in the dehumidifying and heating assembly housing D341. The connecting seal is preferably made of foam, silicone, or soft rubber. The insulating member is preferably made of a heat-insulating material. However, the connecting insulation member can also be made of a cheaper metal or alloy, where the metal or alloy has good thermal conductivity but can still provide a certain level of heat insulation even when covered with the connecting seal.

[0115] Figure 13 is a perspective view showing the dehumidification condensation pipe integrated body D351 of the dehumidification condensation assembly D35 in the first embodiment of the combined washer-dryer machine according to the present invention. Figure 14 is a perspective view showing the cut-off portion of the dehumidification condensation assembly housing D352 of the dehumidification condensation assembly D35 in the first embodiment of the combined washer-dryer machine according to the present invention. The dehumidification condensation assembly includes the dehumidification condensation pipe integrated body D351, the dehumidification condensation assembly housing D352, and a dehumidification condensation outlet pipe. The dehumidification condensation pipe integrated body D351 is fixed to the middle of the dehumidification condensation assembly housing D352 and is configured to condense and dehumidify the dehumidified water flowing through the dehumidification condensation pipe integrated body D351. The condensed water is discharged from the dehumidification condensation outlet pipe.

[0116] As shown in Figure 13, the dehumidifying condensation assembly D35 shares a single module lower housing with the moisture absorption runner assembly D11, moisture absorption passage fan D23, and dehumidifying passage fan D33. The dehumidifying condensation pipe integrated body D351 is fitted into the module lower housing via a retaining rod and a restricting member, and the upper housing of the dehumidifying condensation assembly housing D352 presses downward on the sealing piece around the dehumidifying condensation pipe integrated body D351 to provide a seal.

[0117] As shown in FIG. 14, a baffle D353 is provided between the dehumidifying condensing pipe integrated body D351 and the dehumidifying condensing assembly housing D352 to prevent the dehumidifying flow from entering the dehumidifying condensing assembly housing D352, bypassing the dehumidifying condensing pipe integrated body D351, and directly flowing into the outlet of the dehumidifying condensing assembly housing through the gap between the dehumidifying condensing assembly housing D352.

[0118] 7 and 14, the drying module D can be pre-assembled as a single pre-assembled module prior to the assembly of the entire combined washer-dryer machine W. The pre-assembled module includes only an integrally constructed lower module housing and a plurality of separate upper module housings, and the lower and upper module housings form a plurality of chambers configured to accommodate each functional module of the drying module, such as the moisture absorption runner assembly D11, moisture absorption passage fan D23, dehumidification passage fan D33, runner drive mechanism D13, dehumidification heating assembly D34, and dehumidification condensing assembly D35. Manufacturing the drying module as a single module significantly simplifies assembly and improves assembly efficiency, while eliminating or shortening the corresponding connecting ducts, resulting in a more compact structure for the drying module.

[0119] 15 is a perspective view schematically illustrating a pipe assembly P in a combined washer-dryer machine according to the present invention. The pipe assembly P includes an inlet pipe P1, a first outlet pipe P2, a second outlet pipe P3, and a third outlet pipe P4. One end of the inlet pipe P1 is connected to a water pipe, and the other end of the inlet pipe P1 is connected to one end of the first outlet pipe P2, one end of the second outlet pipe P3, and one end of the third outlet pipe P4, respectively. The other end of the first outlet pipe P2 is connected to the water inlet of the dehumidifying and condensing assembly D35. The other end of the second outlet pipe P3 is connected to the water inlet of the detergent dispenser box C. The other end of the third outlet pipe P4 is connected to the water inlet of the air outlet duct L1. Through this composite pipe system, water from the water pipe is transported to the dehumidifying and condensing assembly D35, the detergent dispenser box C, and the air outlet duct L1, respectively, to meet the water demand. The dehumidifying condenser assembly D35, detergent dispenser box C, water inlet of air outlet duct L1, and pipe assembly P are all located above drum R, making full use of the space above drum R and resulting in a very compact overall layout of combined washer-dryer machine 1. This layout facilitates the layout of piping from pipe assembly P to the water inlets of each assembly, minimizing the overall piping length. Specifically, dehumidifying condenser assembly D35, detergent dispenser box C, water inlet of air outlet duct L1, and pipe assembly P are located at the four corners of combined washer-dryer machine 1. Air outlet duct L1 is located at the rear right of drum R, and the water inlet of air outlet duct L1 and pipe assembly P are located at the rear right corner of combined washer-dryer machine W, shortening the piping length from third outlet pipe P4 of pipe assembly P to the water inlet of air outlet duct L1. Solenoid valves are provided in the inlet pipe P1 and / or the first outlet pipe P2 and / or the second outlet pipe P3 and / or the third outlet pipe P4 to control the on / off and / or flow rate of the water pipes. Each duct or water inlet is connected by a hose, and the use of the hose allows the pipes to be flexibly placed in the gaps between each assembly.

[0120] FIG. 16 is a perspective view showing a longitudinal cross section of an air outlet duct L1 equipped with a filter mesh self-cleaning device in a combined washer-dryer machine according to the present invention. The air outlet duct L1 is installed in close contact with the drum R, extending from bottom to top at the rear of the drum R. This extension reduces the overall height of the combined washer-dryer machine 1, allowing it to be easily installed under a table facet. The air outlet duct L1 is connected to the outlet of the drum R at a first end L11 and to the drying module D at a second end L12. The air outlet duct L1 includes a first half-housing L13 and a second half-housing L14, defining a cavity therebetween. The second half-housing L14 has an inlet (not shown) at the first end L11 of the air outlet duct L1 for connection to the outlet of the drum R, and the first half-housing L13 preferably has an arc-shaped inner surface at the end opposite the inlet for guiding the airflow entering the cavity. The first half-housing L13 has an arc-shaped support plate L15 at its second end L12. The first end is attached to the top plate L131 of the first half-housing L13, and the second end extends into the cavity. The arc-shaped support plate L15 helps guide the filtered airflow and prevent turbulence. The second end of the arc-shaped support plate L15 allows the filtering mesh F1 to be obliquely installed in the cavity from the bottom of the second half-housing L14 to the top of the first half-housing L13, dividing the cavity into an uncleaned space and a cleaned space. In other embodiments, the support plate L15 may have other configurations and shapes, such as a flat plate, with one end fixed to the top of the first half-housing L13 and the other end extending into the uncleaned space to secure the top edge of the filtering mesh F1. The inclination angle of the filtering mesh F1 can be adjusted as needed to improve flushing efficiency. All airflow entering the cavity through the inlet at the first end L11 of the air outlet duct L1 first flows into the uncleaned space, passes through the inlet face F11 and the cleaning face F12 of the filtering mesh F1, enters the cleaning space, and is then transported to the drying module through the outlet at the second end L12 (not shown) of the air outlet duct L1. Due to this arrangement of the filtering mesh F1, inclusions filtered by the filtering mesh F1 are mainly deposited on the inlet face F11.

[0121] To clean the filter mesh F1, a filter mesh self-cleaning device F2 is installed at the second end L12 of the air outlet duct L1. Tap water containing detergent is sprayed onto the filter mesh F1 from one side of the inlet face F11 of the filter mesh F1 on one side of the uncleaned space to flush out lint and other debris from the filter mesh F1. After flushing the filter mesh, the used tap water is discharged from the combined washer-dryer machine through a water outlet (not shown) at the first end L11 of the air outlet duct L1, for example, through a dedicated drain outlet for the self-cleaning liquid or the drum drain. A filter mesh self-cleaning device is installed on one side of the cleaning space to flush the cleaning surface of the filter mesh F1 synchronously or asynchronously, achieving more thorough cleaning of the filter mesh.

[0122] FIG. 17 is a schematic cross-sectional view of the filter mesh self-cleaning device F2 in a combined washer-dryer machine according to the present invention, taken along line AA in FIG. 16. The filter mesh self-cleaning device F2 includes an inlet pipe F21 and a nozzle F22 connected to the inlet pipe. The inlet pipe F21 is fixed by sealing to the top panel L131 of the air outlet duct L1 on one side of the uncleaned space and is connected to a tap water inlet pipe, for example, via a hose extending beyond the drum R. The nozzle F22 connected to the inlet pipe is located at the top of the filter mesh F1 and sprays tap water (containing detergent) onto the inlet surface F16 of the filter mesh F1. In another embodiment, a pressure valve is provided upstream of the inlet pipe F21 to pressurize the tap water entering the filter mesh self-cleaning device and flush the filter mesh F1 with the pressurized tap water, contributing to improved cleaning efficiency and cost efficiency. In another embodiment, the inlet pipe F21 may be fixed to the first half-housing L13 via another type of support plate, such as the flat plate type described above.

[0123] In this embodiment, the nozzle F22 includes an adapter F23 connected to the inlet pipe F21 and a tapered extension F24 integrally molded with the adapter F23. The adapter F23 is fixedly connected to the inlet pipe F21, for example, by a threaded connection, an interference fit, a binder, or other means. The tapered extension F24 is inclined at a certain angle relative to the filtering mesh F1, and its free end has a cavity extending beyond the air outlet duct L1 and an outlet covering substantially the entire width of the filtering mesh F1 (as shown in FIG. 3), ensuring a cleaning range. Preferably, the angle between the tapered extension F24 and the filtering mesh F1 is between 0° and 45°, more preferably between 5° and 35°. If the angle is too large, the flow of tap water from the top of the filtering mesh F1 to the bottom of the filtering mesh F1 will be poor, resulting in reduced cleaning efficiency. Preferably, the tapered extension is tapered along its length (i.e., in the direction of inclination) to form a flat opening at the free end of the tapered extension, which can increase water pressure, improve impact force on the filtration mesh F1, and further improve cleaning efficiency.

[0124] As shown in FIG. 16, the air outlet duct L1 includes a double-walled duct, forming a chamber for the cooling water flow of the cooling passage L10. The direction of water flow A1 is indicated by the arrow and is opposite the direction of air flow A2, promoting cooling and liquefaction of the air. The cooling passage L10 introduces cooling water to the outer wall of the air outlet duct L1, cooling and liquefying the air flow. This pre-dehumidifies the humid air discharged from the drum R before it enters the drying module D, thereby reducing the load on the dehumidifier in the drying module and improving dehumidification efficiency. A condensing mechanism K is located at a first end of the cooling passage L10 near the drying module D. The condensing mechanism K includes an inlet pipe K1 and a water injection nozzle K2 connected to the inlet pipe K1. The inlet pipe K1 is sealed to the first end of the cooling passage L10, for example, by a combination of threading and a sealant, and is connected to the tap water inlet pipe of the combined washer-dryer W, for example, by a solenoid valve. In this embodiment, the inlet pipe K1 of the condensing mechanism 9 simultaneously constitutes the first water inlet of the air outlet duct L1 or the cooling passage L10. The water injection nozzle K2 is configured to inject cooling water onto the outer wall of the air outlet duct L1 to enhance the cooling effect of the cooling water on the outer wall. Preferably, the water injection nozzle K2 includes a tapered extension that tapers along its length and forms a flat opening at its free end, thereby increasing the injection range and water pressure and further improving the cooling effect on the outer wall of the air outlet duct. Preferably, the cooling passage L10 is provided with multiple water injection nozzles K2, particularly, multiple water injection nozzles K2 may be provided at intervals along the outer wall of the air outlet duct L1 in the circumferential direction. This is particularly advantageous when the cooling passage L10 completely covers the first and second half housings L3 and L14 of the air outlet duct L1 in the circumferential direction. Alternatively, the water injection nozzle K2 may be a 360° automatic rotating nozzle, which increases the injection range and enhances the cooling effect on the outer wall of the air outlet duct. A first drain port is provided at a second end of the cooling passage L10 near the drum R for discharging the cooling water.

[0125] 18 and 19 are perspective views showing second and third embodiments of the combined washer-dryer machine according to the present invention. Unlike the first embodiment in which the drying module D is disposed above the drum R, in the second embodiment, the drying module D' is disposed behind the drum R'. Here, an air outlet duct L1' is disposed above the drum R' and between the drying module D' and the drum R', connecting the air outlet of the drum R' to the air inlet of the drying module D', i.e., the moisture absorption passage air inlet, and an inlet duct L2' is disposed above the drum R', connecting the air inlet of the drum R' to the air outlet of the drying module D', i.e., the moisture absorption passage air outlet. In the third embodiment, the drying module D'' is disposed below the drum R''. Here, an air outlet duct L1'' is disposed above and behind the drum R'', connecting the air outlet of the drum R'' to the air inlet of the drying module D'', i.e., the moisture absorption passage air inlet, and an inlet duct L2'' is disposed above and behind the drum R'', connecting the air inlet of the drum R'' to the air outlet of the drying module D'', i.e., the moisture absorption passage air inlet. The arrangement of the first embodiment provides a particularly compact structure, with the drum R as a horizontal cylinder leaving more space above its left and right sides to accommodate the functional assemblies in the drying module D, and the drying module D being located above the drum for easier assembly and maintenance. The arrangement of the second embodiment further reduces the height of the combined washer-dryer and is suitable for environments where the height of the combined washer-dryer is sensitive. The third embodiment facilitates expansion when multiple drums share one or fewer drying modules. For example, a second drum can be added below the drying module D'' shown in FIG. 16, and a switching mechanism can be added in the space between the two drums to selectively fluidly connect the drying module D'' to one of the drums, making it suitable for large laundry rooms.

[0126] The drying modules described above can also be used in a variety of applications where dehumidification is required, such as clothes dryers, dehumidifiers, dishwashers, etc.

[0127] The above embodiments are used for illustration and explanation, and are not intended to limit the scope of the present invention to the described embodiments. In other words, the present invention can be embodied in various other combinations of the features described above, and is not limited to the illustrated and described embodiments.
