DETAILED DESCRIPTION

[0069] For the purposes of the present application, the technical solutions and advantages will be more apparent from the following detailed description of the embodiments of the present application, combined with the drawings.

[0070] The following description relates to the drawings, in which the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following example embodiments are illustrative of all implementations consistent with the present application. They are not meant to limit the scope of the application as described in the appended claims.

[0071] In the description of the present application, it is understood that the terms "first", "second" and the like are only set for the purpose of description, and cannot be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances. In addition, in the description of the present application, "a plurality of" means two or more, unless otherwise specified. The association relationship of the associated objects is described, which means that there can be three kinds of relationships, for example, A and / or B can represent the following three cases: A exists alone, A and B exist together, and B exists alone. The character " / " generally represents an "or" relationship between the associated objects before and after it.

[0072] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. The term "and / or" used herein includes any and all combinations of one or more associated listed items.

[0073] As shown in FIGS. 1-6, the present application provides a power transmission assembly 31, which is adapted to be provided in a clothes treatment apparatus 1. The clothes treatment apparatus 1 includes a clothes containing tub 20, which is supported by at least two support wheels 3 at both the front end and the rear end thereof in the axial direction.

[0074] In this case, both ends of the clothes containing tub 20 in the axial direction are supported by at least two support wheels 3, so that a support shaft does not need to be provided at the rear end of the clothes containing tub 20.

[0075] The clothes treatment apparatus 1 described above has a drying function, and can be a clothes dryer or a washer-dryer. The clothes dryer refers to an apparatus having a drying function. The washer-dryer refers to an apparatus that integrates a drying function and a washing function, and the clothes treatment cavity can be provided for washing and drying. The washing can include cleaning and dehydration.

[0076] The rotational axis of the clothes containing tub 20 described above can extend in the horizontal direction, in which case the clothes treatment apparatus 1 can be a drum-type clothes treatment apparatus 1. For example, in the case where the rotational axis of the clothes containing tub 20 extends in the horizontal direction, the clothes containing tub 20 drives the clothes to move from the lower side to the upper side during rotation. The clothes fall from the upper side to the lower side under the action of gravity, so that the clothes are dispersed, tumbled, and changed in posture under the combined action of the clothes containing tub 20 and gravity.

[0077] In addition, the clothes containing tub 20 described above is substantially hollow and cylindrical, and can be a single tub structure, that is, the clothes treatment apparatus 1 has only one tub, which is the clothes containing tub. Alternatively, the clothes containing tub 20 can be provided with an outer tub, in which case the clothes treatment apparatus 1 has two tubs. In addition, the clothes containing tub 20 can be made of a metal material, such as stainless steel.

[0078] Referring to FIGS. 1-2, the power transmission assembly 31 includes a receiving coil 131 and a transmitting coil 121, at least one of which is a non-annular structure, and the receiving coil 131 can be disposed at the rear end of the drum 20 outside the laundry treatment cavity 20a of the drum 20.

[0079] Understandably, since the laundry treatment apparatus 1 cancels the support shaft at the rear end of the drum 20, the receiving coil 131 and the transmitting coil 121 described above can be designed as a non-annular structure, thereby enabling the receiving coil 131 and / or the transmitting coil 121 to occupy less space at the same transmission efficiency, facilitating the arrangement of the receiving coil 131 and / or the transmitting coil 121, and enabling the transmission efficiency of the receiving coil 131 and / or the transmitting coil 121 to be increased at the same occupied space.

[0080] Here, the transmitting coil 121 and the receiving coil 131 can achieve contactless power transmission, that is, the transmission of electrical energy between the two without the use of a connecting wire, so that the transmitting coil 121 and the receiving coil 131 can still achieve the transmission of electrical energy when the drum 20 is in a rotating state.

[0081] Illustratively, the transmitting coil 121 and the receiving coil 131 transmit energy through a magnetic field, for example, the transmitting coil 121 can generate a varying magnetic field, and the receiving coil 131 can generate an electric current through magnetic induction, thereby achieving the transmission of electrical energy.

[0082] It should be noted that it is preferable for both the transmitting coil 121 and the receiving coil 131 to be non-annular structures. Of course, it is also possible for the receiving coil 131 to be a non-annular structure while the transmitting coil 121 is an annular structure. Or the receiving coil 131 is an annular structure while the transmitting coil 121 is a non-annular structure.

[0083] Here, the non-annular structure can be a polygonal shape, a circular shape, an elliptical shape, or an irregular shape. The irregular shape is a shape of the receiving coil 131 and / or the transmitting coil 121 other than regular shapes such as a square, a rectangle, a circle, and an ellipse. The non-annular structure can also be a regular shape other than a square, a circle, and an ellipse, such as a trapezoid, a rhombus, and the like, which will not be listed one by one here.

[0084] Understandably, the non-annular structure described above can be selectively provided as a regular shape or as an irregular shape, so that the processing requirements for the transmitting coil 121 and / or the receiving coil 131 can be reduced, thereby reducing processing costs and improving processing efficiency.

[0085] Exemplarily, referring to FIG. 2, the shape of the receiving coil 131 is square, and the shape of the transmitting coil 121 is preferably square, and can also be selected as other shapes such as a ring shape, a circular shape, etc.

[0086] In some embodiments, the power transmission assembly 31 further comprises a magnetic isolation member 312, which is arranged on one side of the receiving coil 131, and the projection of the receiving coil 131 on a plane parallel to the receiving coil 131 is located within the projection of the magnetic isolation member 312 on the plane. The magnetic isolation member 312 can be arranged between the receiving coil 131 and the drum 20.

[0087] Understandably, by arranging the magnetic isolation member 312, the receiving coil 131 and the drum 20 can be completely separated, so as to avoid heating of the drum 20 by the magnetic leakage of the receiving coil 131, and to affect the power transmission efficiency. When the power transmission assembly 31 is arranged at the rear end of the drum 20, the projection of the receiving coil 131 on the drum 20 is located within the projection of the magnetic isolation member 312 on the drum 20.

[0088] It should be noted that the shape of the magnetic isolation member 312 can be selected as a regular shape such as a square, a rectangle, a circle, etc., or can also be selected as an irregular shape. In addition, the material of the magnetic isolation member 312 can be selected as ferrite, or can also be selected as other materials.

[0089] The laundry treating apparatus 1 further comprises a base (not shown in the drawings), on which the support wheels 3 are arranged. The support wheels 3 provide support for the drum 20, so that the drum 20 can stably rotate.

[0090] Exemplarily, referring to FIG. 2, the support wheels 3 are arranged in four, two of which are arranged at the front end of the drum 20, and the other two are arranged at the rear end of the drum 20, so that the drum 20 is stably supported by the four support wheels 3.

[0091] Referring to FIG. 3, the laundry treating apparatus comprises the drum 20 and the power transmission assembly 31, and further comprises a cabinet 10, the drum 20 is rotatably arranged in the cabinet 10, the transmitting coil 121 is arranged on the cabinet 10, and the receiving coil 131 is arranged on the drum 20. The base is connected to the cabinet 10.

[0092] Understandably, the receiving coil 131 rotates with the drum 20, while the transmitting coil 121 is arranged on the cabinet 10 and remains stationary, so that the receiving coil 131 rotates relative to the transmitting coil 121.

[0093] Further, the centers of the receiving coil 131 and the transmitting coil 121 are located on the rotation axis of the clothes containing drum 20. In this way, the relative positions of the receiving coil 131 and the transmitting coil 121 remain unchanged during the rotation of the receiving coil 131 with the clothes containing drum 20, so that the receiving coil 131 and the transmitting coil 121 can realize stable transmission of electric energy.

[0094] Referring to FIGS. 3 and 4, the clothes treating apparatus 1 further includes a lifting rib 4 disposed on the clothes containing drum 20 and located in the clothes treating cavity 20a, and an electric component (not shown in the drawings) disposed inside or on the outer surface of the lifting rib 4. The receiving coil 131 is configured to supply power to the electric component.

[0095] Understandably, the clothes treating cavity 20a is configured to place clothes, the clothes containing drum 20 can rotate, and the lifting rib 4 can contact the clothes in the clothes treating cavity 20a and drive the clothes to rotate with the clothes containing drum 20. For example, the clothes move upward under the action of the lifting rib 4 and then move downward under the action of gravity and / or centrifugal force, so that the clothes continuously change posture in the clothes treating cavity 20a. The receiving coil 131 disposed on the clothes containing drum 20 provides power to the electric component, which can avoid the problem of line entanglement when the electric component rotates with the clothes containing drum 20.

[0096] The electric component can be selected as a heating component, such as a graphene heating sheet, which is disposed on the surface of the lifting rib 4 and can directly contact the clothes in the clothes treating cavity 20a, so as to dry the clothes. Alternatively, the electric component can also be selected as an electric conductivity detection component, which is disposed on the outer surface of the lifting rib 4 and is configured to detect the electric conductivity of the clothes in the clothes treating cavity 20a. The clothes treating apparatus 1 can determine the drying degree of the clothes according to the electric conductivity detected by the electric conductivity detection component. For example, the principle of the electric conductivity detection component can be that the clothes in the clothes treating cavity 20a contact two electrode pieces of the electric conductivity detection component, so that the electric conductivity detection circuit is turned on. The resistance of clothes with different moisture levels is different, that is, the electric conductivity is related to the moisture level of the clothes, and the drying degree of the clothes can be determined according to the electric conductivity of the clothes.

[0097] The electric conductivity detection component can be disposed on the outer surface of the lifting rib 4, so that the electric conductivity detection component can directly contact the clothes in the clothes treating cavity 20a, so as to perceive the drying degree of the clothes at close range, effectively improving the accuracy of determining the drying degree of the clothes in the clothes treating cavity 20a. Of course, the electric conductivity detection component can also be disposed on the clothes containing drum 20, and the detection of electric conductivity can also be realized.

[0098] The lifting rib 4 is formed with a receiving groove 41a. The laundry treating apparatus 1 further includes a cable and a control board disposed in the receiving groove 41a, the cable being connected to the receiving coil 131 and the control board, and the control board being connected to the electric component.

[0099] The cable can transmit an electrical signal, and the control board can control the on-off of the power supply, such as controlling the transmission of the electrical energy between the receiving coil 131 and the electric component, that is, controlling the start-stop of the electric component. The control board is disposed in the receiving groove 41a of the lifting rib 4, and the electric component is disposed on the lifting rib 4, facilitating the electrical connection between the control board and the electric component.

[0100] The control board can include an MCU, i.e., a micro controller unit. It can be configured to realize input functions such as signal acquisition and processing, and output functions such as issuing instructions to control the operation of the actuator. For example, the control board can control the on-off of the power supply.

[0101] Understandably, the receiving coil 131, the control board, the cable and the electric component rotate synchronously with the clothes containing drum 20, so that the rotation of the clothes containing drum 20 does not cause the cable to be entangled.

[0102] Further, the clothes containing drum 20 is provided with a wire passing hole through which the cable passes, and the lifting rib 4 covers the wire passing hole. In this way, one end of the cable is connected to the receiving coil 131, and the other end passes through the wire passing hole and enters the receiving groove 41a to be connected to the control board, which can reduce the situation of the cable being entangled. Moreover, the lifting rib 4 covers the wire passing hole, which can avoid the cable being exposed in the laundry treating cavity 20a, thereby avoiding the clothes contacting the cable.

[0103] In addition, the cable is sealed in the wire passing hole, such as being sealed by a sealing ring, sealing glue or other sealing structure to seal the gap between the cable and the wire passing hole, so as to avoid the wire passing hole from leaking water or air when the laundry treating apparatus 1 is a washer-dryer.

[0104] Referring to FIG. 4, the clothes containing drum 20 includes a drum body 201 and a rear end cover 202 connected to each other, the drum body 201 has a laundry dropping opening at the front side, and the rear end cover 202 closes the rear end opening of the drum body 201, the wire passing hole is formed in the rear end cover 202, and the receiving coil 131 is disposed on the rear end cover 202 and located outside the laundry treating cavity 20a. The lifting rib 4 is disposed on the drum body 201 and extends to the rear end cover 202 to cover the wire passing hole.

[0105] Exemplarily, referring to FIGS. 5 and 6, the lifting rib 4 includes a main body part 41 and an extension part 42 connected to the main body part 41, the main body part 41 is formed with the receiving groove 41a, and the extension part 42 covers the wire passing hole.

[0106] The extension 42 is provided with a wire cavity for a cable to pass through. The surface of the extension 42 facing the rear side is attached to the rear surface of the clothes treatment cavity 20a, i.e. the side surface of the rear end cover 202 facing the clothes treatment cavity 20a. The wire cavity can be sealed through the rear surface of the clothes treatment cavity 20a, so as to prevent water or lint in the clothes treatment cavity 20a from entering the wire cavity.

[0107] The main body 41 comprises two side plates 411, a top plate 412 and an end plate 413. The two side plates 411 are arranged along the circumference of the clothes containing drum 20 and connected to the circumferential side wall of the clothes containing drum 20 at the bottom ends. The top plate 412 is connected to the top ends of the two side plates 411. The end plate 413 is connected to the front ends of the two side plates 411. The top plate 412, the end plate 413 and the two side plates 411 together define a receiving groove 41a. The rear ends of the two side plates 411 are connected to the extension 42.

[0108] It should be noted that the side plates 411 and the end plate 413 are sealingly connected to the circumferential side wall of the clothes containing drum 20, so as to ensure the sealing of the receiving groove 41a.

[0109] Further, the lifting rib 4 further comprises a reinforcing portion 43 arranged in the receiving groove 41a, so as to improve the structural strength of the lifting rib 4. The reinforcing portion 43 comprises a partition plate and a reinforcing rib plate arranged in the receiving groove 41a.

[0110] The clothes treatment apparatus 1 comprises a circulating air duct. The rear side wall of the clothes containing drum 20 is provided with at least one air inlet communicating with the clothes treatment cavity 20a. The circulating air duct communicates the air inlet with an air outlet of the clothes treatment cavity 20a. For example, the rear side wall of the clothes containing drum 20 is provided with an air inlet. The circulating air duct is arranged to provide a circulating air flow repeatedly flowing through the clothes treatment cavity 20a. The air flow of the circulating air duct can enter the clothes treatment cavity 20a through the air inlet. The air flow in the clothes treatment cavity 20a can enter the circulating air duct through the air outlet. The air flow can circulate between the circulating air duct and the clothes treatment cavity 20a.

[0111] It should be understood that the number of air inlets can be one or more, for example, two, three, four or five, etc.

[0112] In an embodiment, the clothes treating apparatus 1 comprises a wind cover. The above-mentioned base is located in the cabinet 10 and below the clothes containing drum 20, and the rear side wall of the cabinet 10 is formed with an air return opening and an air supply opening in communication with the air inlet opening, the height of the air return opening being lower than the height of the air supply opening. The base is formed with a heat exchange channel, two ends of the heat exchange channel being in communication with the air outlet opening and the air return opening respectively. The wind cover covers the periphery of the air supply opening and the air return opening, and cooperates with the rear side wall of the cabinet 10 to define an air supply channel. The heat exchange channel and the air supply channel jointly constitute a circulating air duct. The heat exchange channel is located upstream of the air supply channel along the flow direction of the air flow in the circulating air duct, and the air flow flows through the air outlet opening, the heat exchange channel, the air return opening, the air supply channel, the air supply opening and the air inlet opening in sequence. The cabinet 10 can be substantially hexahedral, for example, a square or a cuboid.

[0113] The number of air supply openings is not limited, and the air supply opening can be one or more, for example, two, three, four or five, etc.

[0114] Further, the clothes treating apparatus 1 comprises a heat exchange assembly located in the heat exchange channel, and the heat exchange assembly is arranged to exchange heat with the air flow in the heat exchange channel, thereby dehumidifying and heating. The humid and hot air flow in the clothes treating cavity 20a can enter the heat exchange channel through the air outlet opening, and is converted into dry and hot air flow after heat and mass exchange with the heat exchange assembly, and then enters the air supply channel through the air return opening, and then returns to the clothes treating cavity 20a through the air supply opening and the air inlet opening.

[0115] The above-mentioned heat exchange assembly comprises a condenser and an evaporator, and the clothes treating apparatus 1 further comprises a compressor and a throttling device, and the compressor, the condenser, the throttling device and the evaporator are connected by pipelines to constitute a heat pump system, and the refrigerant can circulate in the heat pump system. The air flow in the circulating air duct exchanges heat with the refrigerant in the evaporator and the condenser to form dry and hot air flow. The evaporator is arranged to cool and dehumidify the humid and hot air flow from the clothes treating cavity 20a into dry and cold air flow, and the condenser heats the dry and cold air flow into dry and hot air flow to return to the clothes treating cavity 20a.

[0116] The working principle of the heat pump system is as follows: the compressor sucks in low-pressure gaseous refrigerant and compresses it to be discharged in a high-pressure state; the high-pressure refrigerant discharged into the condenser transfers heat to the air flow to condense into high-pressure liquid; the high-pressure liquid refrigerant flows through the throttling device to be throttled and decompressed to become a low-pressure and low-temperature gas-liquid two-phase mixture into the evaporator; the refrigerant in the evaporator absorbs the heat of the air flow to become low-pressure gaseous state; the low-pressure gaseous refrigerant is sucked into the compressor again; the heat exchange is realized through the repeated circulation. That is, the evaporator is arranged to cool and dehumidify the wet and hot air flow from the clothes treatment cavity 20a to form a dry and cold air flow, and the condenser heats the dry and cold air flow into a dry and hot air flow to flow back into the clothes treatment cavity 20a, and the dry and hot air flow flowing back into the clothes treatment cavity 20a contacts the wet clothes to form a wet and hot air flow again, and a drying cycle is completed. Through repeated operation of the drying cycle, the circulating air flow is continuously provided to the clothes treatment cavity 20a to dry the clothes.

[0117] Exemplarily, the evaporator and the condenser can both be finned tube heat exchangers.

[0118] Exemplarily, the throttling device includes but is not limited to an electronic expansion valve and the like.

[0119] Further, the clothes treatment apparatus 1 includes a fan wheel arranged to drive the air flow. Exemplarily, the fan wheel is located in the heat exchange channel and between the heat exchange assembly and the air return port. In the process of drying the clothes, the fan wheel is arranged to drive the air flow flowing through the clothes to flow through the evaporator and the condenser in sequence and then blow to the clothes to form a circulating air flow, so that the fan wheel can accelerate the air flow and improve the drying efficiency.

For example, the receiving power transmission component 31b can be arranged at a rear side wall of the clothes holding drum 20 facing the rear side.

[0133] The receiving coil 131 is arranged to receive the electromagnetic signal transmitted by the transmitting coil 121 and generate an induced current. The transmitting coil 121 generates a varying magnetic field. The receiving coil 131 generates an induced current through electromagnetic induction. The receiving coil 131 receives the power transmission from the transmitting coil 121 and outputs the power. The transmitting coil 121 and the receiving coil 131 achieve power transmission through electromagnetic induction. That is, the transmitting coil 121 can wirelessly transmit power to the receiving coil 131.

[0134] At least one of the transmitting coil 121 and the receiving coil 131 includes a plurality of stacked coil units 40. That is, the transmitting coil 121 can include a plurality of stacked coil units 40. The receiving coil 131 can include a plurality of stacked coil units 40. Both the transmitting coil 121 and the receiving coil 131 can include a plurality of stacked coil units 40.

[0136] The coil unit 40 has a substantially flat structure. That is, the thickness of the coil unit 40 is smaller than the first direction perpendicular to the thickness direction. The coil unit 40 has a substantially flat appearance.

[0137] The plurality of stacked coil units 40 can increase the number of turns of the transmitting coil 121 and / or the receiving coil 131 without increasing the size of the coil unit 40 along the first direction (i.e., the direction perpendicular to the thickness direction of the coil unit 40).

[0138] It can be understood that the plurality of stacked coil units 40 can be connected. For example, the plurality of stacked coil units 40 of the transmitting coil 121 can be connected in series. For another example, the plurality of stacked coil units 40 of the receiving coil 131 can be connected in series.

[0139] The transmitting coil 121 is wirelessly connected to the receiving coil 131. That is, the transmitting coil 121 can wirelessly transmit power to the receiving coil 131. In this way, the electrical element arranged in the clothes holding drum 20 can be electrically connected to the receiving power transmission component 31b (e.g., the receiving coil 131).

In this way, the electric element arranged in the clothes containing drum 20 can perceive the state of the clothes and perform a specific function in close proximity, so as to improve the working performance of the clothes treatment equipment 1. Exemplarily, the drying performance of the clothes treatment equipment 1 can be improved.

[0143] The clothes treatment equipment 1 provided by the embodiment of the present application can transmit electrical energy without contact between the transmitting power transmission component 31a and the receiving power transmission component 31b, and can achieve electrical energy transmission without wire connection, so the reliability is high. The receiving power transmission component 31b is arranged in the clothes containing drum 20, and the receiving power transmission component 31b can receive the electrical energy and / or signals emitted by the transmitting power transmission component 31a.

[0153] In some embodiments, referring to FIGS. 7-13, the cabinet 10 includes a back plate 11, the clothes containing drum 20 includes a rear end cover 202 and a drum body 201, the rear end cover 202 is arranged at the rear end of the drum body 201 to jointly define a clothes treatment cavity 20a, the receiving power transmission assembly 31b is arranged at the side of the rear end cover 202 facing the back plate 11, and the transmitting power transmission assembly 31a is arranged at the side of the back plate 11 facing the rear end cover 202.

[0154] The back plate 11 refers to a component of the cabinet 10 located at the rear side of the clothes treatment apparatus 1 along the front-rear direction. The rear side refers to the side of the clothes treatment apparatus 1 away from the user after installation. The back plate 11 is located at the rear side of the clothes containing drum 20.

[0155] The front side of the drum body 201 is open to form a clothes throwing opening.

[0156] The receiving power transmission assembly 31b is arranged at the side of the rear end cover 202 facing the back plate 11, i.e., the receiving power transmission assembly 31b is arranged at the rear side of the rear end cover 202.

[0157] The transmitting power transmission assembly 31a is arranged at the side of the back plate 11 facing the rear end cover 202, i.e., the transmitting power transmission assembly 31a is arranged at the front side of the back plate 11.

[0158] In this embodiment, the receiving power transmission assembly 31b is arranged at the side of the rear end cover 202 facing the back plate 11, and the transmitting power transmission assembly 31a is arranged at the side of the back plate 11 facing the rear end cover 202. The distance between the transmitting power transmission assembly 31a and the receiving power transmission assembly 31b is relatively short, which increases the reliability of electric energy transmission.

[0159] In some embodiments, the rear end of the drum body 201 and the rear end cover 202 can be detachably connected or non-detachably connected.

[0160] In some embodiments, the receiving power transmission assembly 31b can be arranged at the side of the rear end cover 202 away from the back plate 11, i.e., the receiving power transmission assembly 31b is arranged at the front side of the rear end cover 202.

[0161] In some embodiments, the transmitting power transmission assembly 31a can be arranged at the side of the back plate 11 away from the rear end cover 202, i.e., the transmitting power transmission assembly 31a is arranged at the rear side of the back plate 11.

[0162] In some embodiments, referring to FIGS. 1-13, the receiving coil 131 and the transmitting coil 121 are arranged opposite to each other along the axial direction of the clothes containing drum 20, and the multi-layer coil unit 40 is stacked along the axial direction of the clothes containing drum 20.

[0163] For example, the receiving coil 131 can include a plurality of coil units 40 stacked in the axial direction, or the transmitting coil 121 can include a plurality of coil units 40 stacked in the axial direction; or both the receiving coil 131 and the transmitting coil 121 can include a plurality of coil units 40 stacked in the axial direction.

[0164] The receiving coil 131 and the transmitting coil 121 are arranged in the axial direction of the drum 20 in a spaced-apart manner, which means that the receiving coil 131 and the transmitting coil 121 are spaced apart in the axial direction, and the projection of the transmitting coil 121 and the projection of the receiving coil 131 overlap at least partially in a projection plane perpendicular to the axial direction.

[0165] In this embodiment, the receiving coil 131 and the transmitting coil 121 are arranged in the axial direction of the drum 20 in a spaced-apart manner, for example, the transmitting coil 121 and the receiving coil 131 can be coaxial and arranged in a spaced-apart manner at all times, that is, regardless of the position of the drum 20, the transmitting coil 121 and the receiving coil 131 are always coaxial and arranged in a spaced-apart manner. For another example, the transmitting coil 121 and the receiving coil 131 can be coaxial and arranged in a spaced-apart manner at a set position, that is, the receiving coil 131 can be moved to the set position coaxial and arranged in a spaced-apart manner with the transmitting coil 121 by rotating the drum 20. In this way, the influence of the rotating drum 20 on the transmitting coil 121 is reduced, and the installation safety is increased. At least one of the receiving coil 131 and the transmitting coil 121 includes a plurality of coil units 40 stacked in the axial direction, which can make full use of the axial spacing between the drum 20 and the cabinet 10, and increase the number of turns of the receiving coil 131 and / or the transmitting coil 121 while maintaining the spacing between the receiving coil 131 and the transmitting coil 121.

[0166] In some embodiments, the transmitting coil 121, the receiving coil 131, and the drum 20 are coaxial.

[0167] The projection of the transmitting coil 121 and the projection of the receiving coil 131 have a coaxial annular structure in a projection plane perpendicular to the axial direction.

[0168] In this embodiment, during the rotation of the drum 20, the receiving coil 131 and the transmitting coil 121 can always maintain a relative state regardless of the position of the receiving coil 131 with the drum 20, which facilitates the receiving coil 131 to continuously and stably receive the electric energy transmitted by the transmitting coil 121, so as to continuously provide electric energy for the electric appliance elements of the drum 20. That is, during the rotation of the drum 20, the receiving coil 131 can always effectively and sufficiently supply power to the electric appliance elements, without the need for additional auxiliary power supply structure, thereby increasing the power supply reliability of the clothes treatment apparatus 1.

[0169] In some embodiments, the clothes treatment apparatus 1 comprises electrical components, and at least one of the electrical components is arranged in the clothes treatment cavity 20a, and the receiving coil 131 is electrically connected to the electrical components.

[0170] In an exemplary embodiment, one, two or more electrical components are arranged in the clothes treatment cavity 20a.

[0171] The receiving coil 131 is electrically connected to the electrical components, and the receiving coil 131 can supply power to the electrical components. The receiving coil 131 and the electrical components can be electrically connected through the conductive wire bundle 70, or the receiving coil 131 and the electrical components can be connected wirelessly without the conductive wire bundle 70.

[0172] In this embodiment, at least one of the electrical components is arranged in the clothes treatment cavity 20a, and the electrical components arranged in the clothes treatment cavity 20a can closely sense the state of the clothes and perform specific functions to improve the working performance of the clothes treatment apparatus 1.

[0174] The lifting rib 4 protrudes radially from the circumferential surface of the clothes treatment cavity 20a. The lifting rib 4 can contact the clothes in the clothes treatment cavity 20a and drive the clothes to rotate with the clothes drum 20. For example, the clothes move upward under the action of the lifting rib 4, and then move downward under the action of gravity and centrifugal force, and so on, so that the clothes continuously change their posture in the clothes treatment cavity 20a.

[0175] In this embodiment, at least part of the at least one electrical component is arranged in the lifting rib 4, and the lifting rib 4 can provide a mounting position for the at least one electrical component.

[0176] In some embodiments, the at least one electrical component is arranged inside the lifting rib 4.

[0177] In an exemplary embodiment, one electrical component is arranged inside the lifting rib 4, or a plurality of electrical components can be arranged inside the lifting rib 4.

[0178] In this embodiment, the lifting rib 4 provides protection for the electrical components arranged inside it, and reduces the probability of the electrical components arranged inside it contacting the clothes.

[0180] In an exemplary embodiment, one electrical component is arranged on the outer surface of the lifting rib 4, or a plurality of electrical components can be arranged on the outer surface of the lifting rib 4.

[0181] In this embodiment, some electric components need to contact the clothes to detect the parameters of the clothes and generate the clothes information, so as to complete the detection of the clothes. The lifting ribs 4 are arranged to contact and drive the clothes to rotate. Arranging this type of electric components on the outer surface of the lifting ribs 4 can increase the contact area and time with the clothes, thereby improving the detection accuracy.

[0182] In some embodiments, referring to FIG. 7 and FIG. 14, the electric components include a detection unit 15 arranged to detect the parameters of the clothes in the clothes treatment cavity 20a.

[0183] For example, the parameters of the clothes include, but are not limited to, the temperature and / or the electrical conductivity of the clothes, etc.

[0184] For example, the detection unit 15 can be arranged on the lifting ribs 4. In this way, the detection unit 15 is facilitated to contact the clothes.

[0185] For example, the parameters of the clothes are the electrical conductivity. The clothes treatment apparatus 1 can determine the drying degree according to the electrical conductivity detected by the detection unit 15. For example, the detection principle of the detection unit 15 can be that the clothes and the like in the clothes treatment cavity 20a contact two detection electrodes 151 of the detection unit 15, so that the detection circuit of the detection unit 15 is turned on. The resistance values of clothes and the like with different moisture levels are different. That is, the moisture level of the clothes and the like is related to the electrical conductivity. The drying degree is determined according to the electrical conductivity.

[0186] In this embodiment, the detection unit 15 is one of the electric components. The receiving coil 131 provides power and / or signals for the detection unit 15. The detection unit 15 is arranged in the clothes treatment cavity 20a. The detection electrodes 151 of the detection unit 15 can contact the clothes and the like in the clothes treatment cavity 20a, so as to perceive the drying degree of the clothes at a close distance, thereby effectively improving the accuracy of determining the drying degree of the clothes and the like in the clothes treatment cavity 20a.

[0187] In some embodiments, referring to FIG. 14, the detection unit 15 includes detection electrodes 151. The detection electrodes 151 can be arranged on the outer surface of the lifting ribs 4.

[0188] In this embodiment, the detection electrodes 151 are arranged on the outer surface of the lifting ribs 4, which facilitates close contact with the clothes and the like.

[0189] For example, the detection electrodes 151 can be located on the outer surface of the lifting ribs 4 along the circumferential direction. For example, part of the detection electrodes 151 is located on one outer side surface of the lifting ribs 4 along the circumferential direction, and the other part is located on the top side surface of the lifting ribs 4 away from the circumferential side wall of the clothes drum 20 along the radial direction.

[0190] The specific structure of the detection electrodes 151 is not limited.

[0191] For example, the detection electrode 151 includes a first electrode piece and a second electrode piece, both of which are located on the outer surface of the reinforcing rib 4. The first electrode piece includes a first connecting structure and at least two first teeth connected to the first connecting structure. The second electrode piece includes a second connecting structure and at least two second teeth connected to the second connecting structure. The first teeth and the second teeth are alternately and spacedly arranged. That is, there is a second tooth between any two adjacent first teeth, and the distance between the first tooth and the second tooth is greater than zero.

[0192] In this embodiment, the first teeth and the second teeth are alternately and spacedly arranged to form an interdigital structure. One first tooth and one second tooth form one electrode pair. The detection electrode 151 has at least two electrode pairs. The clothes contact at least two electrode pairs. The conduction between each electrode pair can be regarded as a resistance. At least two electrode pairs can be regarded as at least two resistances in parallel. Therefore, the detection of the change in electrical conductivity is more sensitive, and the detection accuracy and sensitivity of the detection electrode 151 are improved. To some extent, the problems of incomplete drying or over-drying are reduced, and the drying performance is improved.

[0193] In some embodiments, referring to FIGS. 10 to 12, the clothes treatment apparatus 1 includes a bearing 50. The bearing 50 and the receiving coil 131 are both connected to the end wall 20b of the clothes containing tub 20. The projection of the receiving coil 131 surrounds the projection of the bearing 50 in a plane perpendicular to the axial direction of the clothes containing tub 20.

[0194] For example, the clothes treatment apparatus 1 includes a support shaft, which can be connected to the clothes containing tub 20 through the bearing 50. For example, the support shaft is connected to the inner ring of the bearing 50, and the end wall 20b is connected to the outer ring of the bearing 50. The clothes containing tub 20 rotates relative to the support shaft. The support shaft can provide support force for the clothes containing tub 20 and its load. The bearing 50 can reduce the friction loss between the support shaft and the clothes containing tub 20 during the rotation of the clothes containing tub 20, and facilitate the rotation of the clothes containing tub 20 relative to the support shaft.

[0195] The type of the bearing 50 is not limited. The bearing 50 is a rolling bearing 50, including but not limited to a ball bearing 50, etc.

[0196] In this embodiment, the projection of the receiving coil 131 surrounds the projection of the bearing 50. The receiving coil 131 has a ring structure and can avoid the bearing 50, so that the receiving coil 131 can rotate with the clothes containing tub 20.

[0197] In some embodiments, referring to FIGS. 10 and 11, the end wall 20b forms an air inlet 200a that communicates with the clothes treatment cavity 20a. The air inlet 200a is located on the side of the receiving coil 131 away from the bearing 50.

[0198] It can be understood that the end wall 20b is a side wall of the clothes containing drum 20, for example, the rear end cover 202 can have the end wall 20b, and the end wall 20b is part of the rear end cover 202.

[0199] Exemplarily, in a projection plane perpendicular to the axial direction, the projection of the receiving coil 131 is spaced apart from the projection of the air inlet 200a, and the projection of the receiving coil 131 is located on the inner side of the projection of the air inlet 200a in the radial direction.

[0200] The air inlet 200a is suitable for the airflow to enter the clothes processing cavity 20a.

[0201] As an example, the receiving coil 131 is between the bearing 50 and the air inlet 200a, the distance between the bearing 50 and the air inlet 200a is limited, and the ring width of the receiving coil 131 in the radial direction is limited. The receiving coil 131 can include a plurality of coil units 40 stacked in the axial direction. In this way, in the case that the ring width of the receiving coil 131 in the radial direction is limited, the transmission power of the receiving coil 131 can be increased by the plurality of coil units 40, and the power range that the receiving coil 131 can transmit can be improved, which meets the requirements of the installation size of the receiving coil 131 in a narrow space and meets the requirements of some high-power output.

[0202] In this embodiment, the air inlet 200a is located on the side of the receiving coil 131 away from the bearing 50, and the receiving coil 131 is between the bearing 50 and the air inlet 200a. On the one hand, the axis of the receiving coil 131 coincides with the axis of the clothes containing drum 20, so that the receiving coil 131 is coaxially arranged with the clothes containing drum 20. On the other hand, the bearing 50 and the air inlet 200a can position and limit the receiving power assembly 31b, which reduces the assembly difficulty and improves the assembly efficiency.

[0203] In some embodiments, referring to FIGS. 10 to 12, the end wall 20b includes a core portion 2021, an outer ring structure 2022, and a plurality of support arms 2023. The bearing 50 and the receiving coil 131 are arranged on the core portion 2021, and the outer ring structure 2022 surrounds the outer periphery of the core portion 2021. The plurality of support arms 2023 are spaced apart along the circumferential direction of the core portion 2021, and the support arms 2023 connect the core portion 2021 and the outer ring structure 2022. The core portion 2021, the outer ring structure 2022, and the plurality of support arms 2023 jointly define a plurality of air inlets 200a, and the plurality of air inlets 200a surround the outer periphery of the receiving coil 131.

[0204] Exemplarily, the support arms 2023 can be integrally formed with the core portion 2021 and the outer ring structure 2022; or the support arms 2023 and the core portion 2021 and the outer ring structure 2022 can be connected together by riveting, welding, and / or screw connection, etc., which is not limited herein.

[0205] In this embodiment, the support arm 2023 connects the core 2021 and the outer ring structure 2022 together, so that the end wall 20b, for example, the rear end cover 202, has sufficient structural strength, and the structural stability of the clothes containing drum 20 is increased.

[0206] In some embodiments, referring to FIGS. 7-13, the clothes treating apparatus 1 includes a cabinet 10, a ring-shaped seal 60, and a conductive wire bundle 70. The clothes containing drum 20 is rotatably disposed in the cabinet 10. The receiving energy transmission assembly 31b is disposed on the end wall 20b of the clothes containing drum 20. The end wall 20b forms a wire passing opening 20c that is in communication with the clothes treating cavity 20a. The ring-shaped seal 60 is disposed between the end wall 20b and the cabinet 10 to achieve dynamic sealing between the end wall 20b and the cabinet 10. The wire passing opening 20c is located on the side of the ring-shaped seal 60 that is close to the rotation axis P of the clothes containing drum 20. One end of the conductive wire bundle 70 is electrically connected to the receiving coil 131. The other end of the conductive wire bundle 70 passes through the wire passing opening 20c and extends into the clothes treating cavity 20a.

[0207] In some embodiments, referring to FIGS. 10-12, the air inlet 200a can be located on the side of the ring-shaped seal 60 that is close to the rotation axis P of the clothes containing drum 20. The wire passing opening 20c and the air inlet 200a can both penetrate the end wall 20b.

[0208] The ring-shaped seal 60 is disposed between the end wall 20b and the cabinet 10 to achieve dynamic sealing between the end wall 20b and the cabinet 10. That is, during the rotation of the clothes containing drum 20 relative to the cabinet 10, the ring-shaped seal 60 can achieve sealing between the end wall 20b and the cabinet 10. As an example, the ring-shaped seal 60 can be fixed to the end wall 20b, and the ring-shaped seal 60 is in sealing contact with the cabinet 10. For example, the ring-shaped seal 60 can abut against the back plate 11 of the cabinet 10. In this way, the ring-shaped seal 60, the end wall 20b, and the cabinet 10 together define a sealed passage for the airflow to pass through the sealed passage and enter the air inlet 200a. In this way, the airflow can be prevented from leaking outside the clothes treating cavity 20a to some extent, and the drying efficiency is improved.

[0209] With a plane perpendicular to the axial direction of the clothes containing drum 20 as a projection plane, the projection of the ring-shaped seal 60 is annular. The wire passing opening 20c and the air inlet 200a can both be located on the side of the ring-shaped seal 60 that is close to the rotation axis P of the clothes containing drum 20. That is, the wire passing opening 20c and the air inlet 200a are located on the side of the ring-shaped seal 60 that is radially close to the rotation axis, and the ring-shaped seal 60 can surround the air inlet 200a and the wire passing opening 20c.

[0210] The conductive wire bundle 70 is configured to transmit electrical energy and / or signals. The receiving coil 131 can transmit electrical energy and / or signals to the electrical appliance element through the conductive wire bundle 70.

[0211] The conductive wire bundle 70 passes through the wire passing port 20c and extends into the clothes treatment cavity 20a, so that the electrical appliance elements can be arranged inside the clothes treatment cavity 20a. According to the position requirement of the electrical appliance elements, the conductive wire bundle 70 can be routed outside the clothes treatment cavity 20a and inside the clothes treatment cavity 20a.

[0212] If the wire passing port 20c is located on the side of the annular sealing member 60 away from the rotation axis in the radial direction, the conductive wire bundle 70 needs to pass through the annular sealing member 60, and the annular sealing member 60 abuts against the cabinet 10. During the rotation of the clothes containing drum 20, the annular sealing member 60 abuts against the cabinet 10 and rotates relative to the cabinet 10. The conductive wire bundle 70 is rubbed during the rotation of the annular sealing member 60, and is prone to damage.

[0213] In the present application, since the wire passing port 20c is located on the side of the annular sealing member 60 close to the rotation axis in the radial direction, the conductive wire bundle 70 can not pass through the annular sealing member 60, and the risk of abrasion of the wire bundle can be avoided to some extent.

[0214] In the embodiment, the conductive wire bundle 70 passes through the wire passing port 20c and extends into the clothes treatment cavity 20a, so that the electrical appliance elements can be arranged inside the clothes treatment cavity 20a. According to the position requirement of the electrical appliance elements, the conductive wire bundle 70 can be routed outside the clothes treatment cavity 20a and inside the clothes treatment cavity 20a, reducing the wiring difficulty of the conductive wire bundle 70; the wire passing port 20c is located on the side of the annular sealing member 60 close to the rotation axis P of the clothes containing drum 20, and the conductive wire bundle 70 can not pass through the annular sealing member 60, so that the risk of abrasion of the wire bundle can be avoided to some extent.

[0215] The material of the annular sealing member 60 is not limited. For example, the annular sealing member 60 can include felt. The felt has good wear resistance and elasticity, which can improve the service life and reliability of the annular sealing member 60.

[0216] In some embodiments, the annular sealing member 60 is arranged around the outer ring structure 2022, and at least one of the core portion 2021, the outer ring structure 2022, and the support arm 2023 is provided with the wire passing port 20c.

[0217] The annular sealing member 60 is arranged around the outer ring structure 2022, which means that the annular sealing member 60 extends in a ring shape along the circumference of the outer ring structure 2022. The annular sealing member 60 can surround the support arm 2023 and the core portion 2021.

[0218] At least one of the core portion 2021, the outer ring structure 2022, and the support arm 2023 is provided with the wire passing port 20c. The number of the wire passing port 20c can be one, that is, one of the core portion 2021, the outer ring structure 2022, and the support arm 2023 is provided with the wire passing port 20c. Alternatively, the number of the wire passing port 20c can be two, that is, two of the core portion 2021, the outer ring structure 2022, and the support arm 2023 are provided with the wire passing port 20c. Alternatively, the number of the wire passing port 20c can be three, that is, all of the core portion 2021, the outer ring structure 2022, and the support arm 2023 are provided with the wire passing port 20c. It can be understood that the number of the wire passing port 20c can also be greater than three, which is not limited in the present application.

[0219] In this embodiment, the annular seal 60 is arranged at the radially outer edge region of the end wall 20b, and the annular seal 60 can surround a larger space so as to surround all the air inlets 200a and all the wire passing ports 20c.

[0220] In some embodiments, referring to FIGS. 10 and 11, the wire passing port 20c is arranged at the connection between the support arm 2023 and the outer ring structure 2022. In this way, the distance between the wire passing port 20c and the circumferential side wall of the clothes containing drum 20 and the distance between the wire passing port 20c and the core portion 2021 are moderate. In the embodiment in which the receiving energy transmission assembly 31b is arranged at the core portion 2021 and the electrical appliance element is arranged at the lifting rib 4, one end of the conductive wire harness 70 is electrically connected with the receiving energy transmission assembly 31b, the other end of the conductive wire harness 70 passes through the wire passing port 20c and is electrically connected with the electrical appliance element. The wire passing port 20c arranged at the connection between the support arm 2023 and the outer ring structure 2022 can reduce the wire winding, and the length of the conductive wire harness 70 can be relatively short, and the wiring is simple and compact.

[0221] In some embodiments, referring to FIG. 13, the transmitting energy transmission assembly 31a includes a transmitting bracket 122, and the transmitting coil 121 is arranged at the transmitting bracket 122. The transmitting bracket 122 is connected with the cabinet 10.

[0222] In some embodiments, referring to FIG. 13, the transmitting bracket 122 includes a ring-shaped body 1221 and a connecting lug 1222 connected with the ring-shaped body 1221. The transmitting coil 121 is arranged at the ring-shaped body 1221, and the connecting lug 1222 is connected with the cabinet 10, for example, the back plate 11.

[0223] In this embodiment, the transmitting coil 121 and the annular body 1221 are both annular structures, the annular body 1221 provides a mounting space for the transmitting coil 121, the connecting lug 1222 is connected with the cabinet 10, for example, the back plate 11, the transmitting coil 121 is stably mounted through the annular body 1221 and the connecting lug 1222, the probability of damage of the transmitting coil 121 is reduced, and the working stability of the transmitting coil 121 is increased.

[0224] In some embodiments, the annular body 1221 is formed with a first annular groove, the first annular groove is open toward one side of the clothes containing drum 20, and the transmitting coil 121 is accommodated in the first annular groove.

[0225] The first annular groove is a ring-shaped space defined by the structure of the annular body 1221, the first annular groove is open toward one side of the clothes containing drum 20, which facilitates the relative arrangement of the transmitting coil 121 and the receiving coil 131, and effective power transmission is achieved. The side of the first annular groove facing the back plate 11 can be in a closed state, so as to provide support for the transmitting coil 121 and reduce the probability of the transmitting coil 121 separating from the first annular groove.

[0226] It can be understood that the outer contour shape of the annular body 1221 can be adapted to the outer contour shape of the transmitting coil 121, in other words, the outer contour shape of the annular body 1221 can be substantially the same as the outer contour shape of the transmitting coil 121. For example, the outer contour of the transmitting coil 121 is circular, and the outer contour shape of the annular body 1221 can also be circular. For another example, the outer contour of the transmitting coil 121 is polygonal, and the outer contour shape of the annular body 1221 can also be the same polygonal. In this way, the space size of the first annular groove matches the transmitting coil 121, so as to facilitate the transmitting coil 121 to be placed in the first annular groove.

[0227] The connecting lug 1222 can be detachably connected with the back plate 11, for example, the connecting lug 1222 can be connected with the back plate 11 through screws, which is not limited herein.

[0228] In some embodiments, referring to FIGS. 10 and 11, the receiving power transmission assembly 31b includes a receiving bracket 132, the receiving coil 131 is arranged on the receiving bracket 132, and the receiving bracket 132 is connected with the end wall 20b, for example, the rear end cover 202.

[0229] In some embodiments, referring to FIGS. 10 and 11, the receiving power transmission assembly 31b includes a receiving bracket 132 arranged on the end wall 20b, the receiving bracket 132 includes an annular portion 1321 and a wire bundling structure 1323, the receiving coil 131 is arranged on the annular portion 1321, the wire bundling structure 1323 is connected to the outer circumferential side of the annular portion 1321, and part of the conductive wire bundle 70 is arranged on the wire bundling structure 1323.

[0230] The bundle structure 1323 is arranged to constrain the conductive wire bundle 70, and can provide support and constraint for the conductive wire bundle 70 located thereon, reduce assembly difficulty, and reduce the risk of displacement and misplacement of the conductive wire bundle 70.

[0231] The receiving coil 131 and the annular portion 1321 are both annular structures, and the shape of the receiving coil 131 can be substantially the same as that of the annular portion 1321.

[0232] The bundle structure 1323 is connected to the outer circumferential side of the annular portion 1321, so as to facilitate the conductive wire bundle 70 to extend to the outer circumferential side of the receiving coil 131, thereby facilitating the electrical connection between the conductive wire bundle 70 and the electrical element.

[0233] Taking the end wall 20b of the rear end cover 202 as an example, referring to FIGS. 10 and 11, the annular portion 1321 can be arranged on the core portion 2021, and the bundle structure 1323 can be arranged on the support arm 2023. The support arm 2023 provides support for the bundle structure 1323, increases installation stability, and also facilitates the bundle structure 1323 to avoid the air inlet 200a to avoid blocking the airflow.

[0234] In this embodiment, the bundle structure 1323 is arranged to constrain the conductive wire bundle 70, and in the case that the receiving energy transmission assembly 31b rotates with the drum 20, the risk of displacement and misplacement of the conductive wire bundle 70 is reduced.

[0235] In some embodiments, referring to FIGS. 10 and 11, the receiving support 132 includes a connecting portion 1322 connected to the inner circumferential side of the annular portion 1321. The connecting portion 1322 is arranged to be mounted and fixed to the receiving support 132, for example, the connecting portion 1322 can be connected to the end wall 20b, for example, the rear end cover 202.

[0236] In some embodiments, referring to FIGS. 10 and 11, the annular portion 1321 is formed with a second annular groove 1321a, which is open toward one side of the back plate 11, and the receiving coil 131 is accommodated in the second annular groove 1321a.

[0237] The second annular groove 1321a is a ring-shaped space defined by the structure of the annular portion 1321, and is open toward one side of the back plate 11, facilitating the relative arrangement of the receiving coil 131 and the transmitting coil 121 and achieving effective electrical energy transmission. The side of the second annular groove 1321a toward the rear end cover 202 can be in a closed state, so as to provide support for the receiving coil 131 and reduce the probability of the receiving coil 131 being separated from the second annular groove 1321a.

[0238] The connecting portion 1322 can be detachably connected to the rear end cover 202. For example, the connecting portion 1322 can be connected to the rear end cover 202 by screws, but the present disclosure is not limited thereto.

[0239] It can be understood that the outer contour shape of the annular portion 1321 can be adapted to the outer contour shape of the receiving coil 131, in other words, the outer contour shape of the annular portion 1321 can be substantially the same as the outer contour shape of the receiving coil 131. For example, the outer contour of the receiving coil 131 is circular, and the outer contour shape of the annular portion 1321 can also be circular. For another example, the outer contour of the receiving coil 131 is polygonal, and the outer contour shape of the annular portion 1321 can also be the same polygonal. In this way, the space size of the second annular groove 1321a matches the receiving coil 131, so as to facilitate the receiving coil 131 to be placed in the second annular groove 1321a.

[0240] In some embodiments, the wire bundle structure 1323 forms a threading hole, the wire bundle structure 1323 and the end wall 20b form a threading space, the receiving coil 131 is arranged on the side of the annular portion 1321 away from the end wall 20b, one end of the conductive wire bundle 70 is connected to the receiving coil 131, and the other end of the conductive wire bundle 70 passes through the threading hole and extends along the threading space.

[0241] The wire bundle structure 1323 and the end wall 20b are spaced apart to form a threading space.

[0242] Taking the end wall 20b of the rear end cover 202 as an example, the annular portion 1321 can be arranged on the rear side of the rear end cover 202, and the receiving coil 131 is arranged on the side of the annular portion 1321 away from the rear end cover 202, that is, the receiving coil 131 is arranged on the rear side of the annular portion 1321.

[0243] In this embodiment, the other end of the conductive wire bundle 70 passes through the threading hole and extends along the threading space, that is, a part of the structure of the conductive wire bundle 70 is located between the wire bundle structure 1323 and the end wall 20b, and both the wire bundle structure 1323 and the end wall 20b can limit the conductive wire bundle 70, thereby playing a role of restricting the conductive wire bundle 70.

[0244] In some embodiments, the clothes treatment apparatus 1 includes a rear cover that covers the rear side surface of the back plate 11 and defines a blow channel together with the back plate 11. The back plate 11 forms a blow port, and the sealing channel communicates the blow port and the air inlet 200a. The air flow of the blow channel flows to the clothes treatment chamber 20a through the blow port, the sealing channel, and the air inlet 200a.

[0245] Exemplarily, the clothes holding drum 20 further has an air outlet, and the clothes treatment cavity 20a is in communication with the air inlet 200a and the air outlet. The dry hot air flows into the clothes treatment cavity 20a from the air inlet 200a, and the wet hot air flows out of the clothes treatment cavity 20a from the air outlet. The back plate 11 is formed with an air return port, the height of the air return port is lower than the height of the air supply port, and the rear cover is arranged around the air supply port and the air return port and cooperates with the back plate 11 to define an air supply channel. The air supply channel is in communication with the air return port and the air supply port, and the dry hot air flows into the clothes treatment cavity 20a through the air return port, the air supply channel and the air supply port to dry the clothes.

[0246] Exemplarily, the clothes treatment device 1 can further include a base, and the base has a drying channel therein. The air supply channel and the drying channel jointly form a circulating air channel, the drying channel is located upstream of the air supply channel along the air flow direction in the circulating air channel, and the drying channel is in communication with the air outlet. The air after the heat and moisture exchange with the clothes can enter the drying channel through the air outlet, complete condensation and dehumidification and heating in the drying channel, and form new dry hot air. The new dry hot air enters the clothes treatment cavity 20a through the air return port, the air supply channel and the air supply port again.

[0247] The number of air supply ports is not limited, and the air supply ports can be one or more, for example, two, three, four or five, etc.

[0248] In some embodiments, the clothes treatment device 1 further includes a heat exchange assembly located in the drying channel. The heat exchange assembly is arranged to exchange heat with the air flow in the drying channel, so as to dehumidify and heat. The wet hot air in the clothes holding drum 20 can enter the drying channel through the air outlet and be converted into dry hot air after heat exchange with the heat exchange assembly. The dry hot air enters the air supply channel through the air return port, and then flows back to the clothes treatment cavity 20a through the air supply port and the air inlet 200a.

[0249] In some embodiments, the heat exchange assembly includes a condenser and an evaporator, and the clothes treatment device 1 further includes a compressor and a throttling device. The compressor, the condenser, the throttling device and the evaporator are connected by pipelines to form a heat pump system, and the refrigerant can circulate in the heat pump system. The air flow in the circulating air channel exchanges heat with the refrigerant in the evaporator and the condenser to form dry hot air. The evaporator is arranged to cool and dehumidify the wet hot air from the clothes treatment cavity 20a into dry cold air; and the condenser heats the dry cold air into dry hot air to flow back to the clothes treatment cavity 20a.

[0250] The working principle of the heat pump system is as follows: the compressor sucks in low-pressure gaseous refrigerant and compresses it into high-pressure gaseous refrigerant, which is discharged into the condenser. The refrigerant in the condenser transfers heat to the air flow to condense into high-pressure liquid. The high-pressure liquid refrigerant is throttled by the throttling device to become a low-pressure low-temperature gas-liquid two-phase mixture, which enters the evaporator. The refrigerant in the evaporator absorbs heat from the air flow to become low-pressure gas, which is sucked into the compressor again. This cycle is repeated to exchange heat. That is, the evaporator is configured to cool and dehumidify the hot and humid air flow from the clothes treatment cavity 20 to form a dry and cold air flow, and the condenser heats the dry and cold air flow to form a dry and hot air flow, which is returned to the clothes treatment cavity 20. The dry and hot air flow returned to the clothes treatment cavity 20 contacts the wet clothes to form a wet and hot air flow again, completing a drying cycle. By repeatedly operating the drying cycle, the clothes treatment cavity 20 is continuously supplied with circulating air flow to dry the clothes.

[0251] Exemplarily, the evaporator and the condenser can both be finned tube heat exchangers.

[0252] Exemplarily, the throttling device includes but is not limited to an electronic expansion valve and the like.

[0253] In some examples, the clothes treatment apparatus 1 further includes an impeller configured to drive the air flow. Exemplarily, the impeller is located in the drying channel and between the heat exchange assembly and the return air inlet. During the drying of the clothes, the impeller is configured to drive the air flow flowing through the clothes to sequentially flow through the evaporator and the condenser, and then blow to the clothes to form a circulating air flow. The impeller can accelerate the air flow and improve the drying efficiency.

[0254] The clothes treatment apparatus 1 (e.g., a clothes dryer) includes a cabinet and a drum arranged in the cabinet. When the clothes treatment apparatus 1 is in operation, in order to more evenly dry the clothes in the drum, the drum can rotate relative to the cabinet. When the clothes in the drum rotate to the top of the drum, they will automatically fall to the bottom of the drum, and then rotate upward with the drum, so as to realize the turnover of the clothes, and achieve the purpose of more evenly drying the clothes.

[0255] In the related art, the drum is provided with some electrical devices (e.g., a humidity sensor). These electrical devices need to be supplied with power to ensure smooth operation. However, since the drum rotates relative to the cabinet when the clothes treatment apparatus 1 is in operation, it is not conducive for the electrical devices to receive power supply from the outside.

[0256] In a third aspect, referring to FIGS. 15-18, FIG. 15 is a partial exploded structural schematic view of a clothes treatment apparatus 1 provided by an embodiment of the present application, and FIGS. 16-18 are partial structural schematic views of the clothes treatment apparatus 1 shown in FIG. 15. In combination with FIGS. 15-18, the clothes treatment apparatus 1 includes a cabinet 10, a clothes containing drum 20, and a wireless energy transmission structure 30.

[0257] The clothes containing cylinder 20 is arranged to contain clothes and the like, and is rotatably connected to the cabinet 10, and is arranged to rotate the clothes contained therein when rotating relative to the cabinet 10, so as to achieve the purpose of treating the clothes. The wireless energy transmission structure 30 is located in the cabinet 10 and includes two energy transmission assemblies 31 that cooperate with each other, and the two energy transmission assemblies 31 are respectively fixed relative to the cabinet 10 and the clothes containing cylinder 20. The two energy transmission assemblies 31 can transmit energy wirelessly, so that the energy transmission assembly 31 fixed relative to the clothes containing cylinder 20 can be powered to the electric component 52 without the need for a conductive wire to connect to an external power source, thereby avoiding interference with the conductive wire during rotation of the clothes containing cylinder 20.

[0258] In some embodiments, the two energy transmission assemblies 31 include a transmitting energy transmission assembly 31a and a receiving energy transmission assembly 31b, the transmitting energy transmission assembly 31a is fixed relative to the cabinet 10, and the receiving energy transmission assembly 31b is fixed relative to the clothes containing cylinder 20. The receiving energy transmission assembly 31b can receive energy transmitted by the transmitting energy transmission assembly 31a wirelessly, so that the receiving energy transmission assembly 31b can be powered without the need for a conductive wire to connect to an external power source, thereby avoiding interference with the conductive wire during rotation of the clothes containing cylinder 20.

[0259] The transmitting energy transmission assembly 31a described above is fixed relative to the cabinet 10, which can be mounted on the cabinet 10, or can be mounted on a structural member on the cabinet 10, such as a wind deflector, etc., without limitation. The receiving energy transmission assembly 31b described above is fixed relative to the clothes containing cylinder 20, which can be mounted on the clothes containing cylinder 20, or can be mounted on a structural member on the clothes containing cylinder 20, without limitation.

[0260] Referring to FIGS. 18-24, FIGS. 19-21 are respectively a front structural schematic view, an exploded structural schematic view, and a partial cross-sectional structural schematic view of the transmitting energy transmission assembly 31a, and FIGS. 22-24 are respectively a front structural schematic view, an exploded structural schematic view, and a partial cross-sectional structural schematic view of the receiving energy transmission assembly 31b. In combination with FIGS. 18-24, the energy transmission assembly 31 includes a coil 311, and at least one energy transmission assembly 31 further includes a magnetic isolation member 312, one side of the magnetic isolation member 312 facing the other energy transmission assembly 31 is formed with a magnetic isolation groove 3121, and the coil 311 is located in the magnetic isolation groove 3121 and connected to the magnetic isolation member 312. It should be noted that one of the energy transmission assemblies 31 can be designed to include the magnetic isolation member 312, or both energy transmission assemblies 31 can be designed to include the magnetic isolation member 312, without limitation.

[0261] The two energy transmission components 31 can transmit electromagnetic energy in the form of an alternating magnetic field to achieve wireless energy transmission between them. For example, the coil 311 of the receiving energy transmission component 31b can receive electromagnetic energy transmitted by the transmitting energy transmission component 31a in the form of an alternating magnetic field, generate an electric current through electromagnetic induction, and achieve wireless energy transmission between the transmitting energy transmission component 31a and the receiving energy transmission component 31b. The coil 311 of the transmitting energy transmission component 31a can be configured to generate an alternating magnetic field.

[0262] In the embodiments of the present application, when the clothes holding drum 20 rotates relative to the cabinet 10, the transmitting energy transmission component 31a and the receiving energy transmission component 31b can still provide power to the power consuming component 52 and other power consuming devices to meet the power consumption demand.

[0263] The coil 311 is connected to the magnetic isolation member 312, which can improve the eddy current effect of the magnetic field generated by the magnetic-electric conversion of the two energy transmission components 31 on other devices (e.g., metal parts) outside the wireless energy transmission structure 30.

[0264] In some embodiments, the coil 311 is located in the magnetic isolation groove 3121 of the magnetic isolation member 312, and the magnetic lines of force generated by the magnetic-electric conversion of the wireless energy transmission structure 30 can be constrained by the inner wall of the magnetic isolation groove 3121. The magnetic lines of force can be constrained from the side of the coil 311 and the side of the coil 311 away from the other energy transmission component 31, which can more effectively constrain the magnetic lines of force and better improve the eddy current effect of the magnetic lines of force on other devices outside the wireless energy transmission structure 30.

[0265] The magnetic isolation member 312 can also be configured to achieve a magnetic concentration effect of the energy transmission component 31, so that the magnetic field is concentrated between the coil 311 and the coil 311 of the other energy transmission component 31, thereby improving the wireless charging efficiency.

[0266] In some embodiments, the coil 311 can be substantially annular. For example, the coil 311 can be an annular structure arranged on the periphery of a rotating shaft (not shown in the figure). The rotating shaft can be arranged outside the clothes holding drum 20 and connected to the clothes holding drum 20, and the clothes holding drum 20 can rotate relative to the cabinet 10 about the rotating shaft. The rotating shaft can be a metal part, and the above-described design of the magnetic isolation member 312 can improve the eddy current effect of the magnetic lines of force generated by the magnetic-electric conversion of the wireless energy transmission structure 30 on the rotating shaft.

[0267] In some embodiments, the magnetic isolation member 312 includes an end plate magnetic isolation portion 3122, an inner ring magnetic isolation portion 3123, and an outer ring magnetic isolation portion 3124. The inner ring magnetic isolation portion 3123 is connected to the end plate magnetic isolation portion 3122. The outer ring magnetic isolation portion 3124 is connected to the end plate magnetic isolation portion 3122 and arranged on the periphery of the inner ring magnetic isolation portion 3123. The outer ring magnetic isolation portion 3124 is arranged apart from the inner ring magnetic isolation portion 3123, and the end plate magnetic isolation portion 3122, the inner ring magnetic isolation portion 3123, and the outer ring magnetic isolation portion 3124 form the magnetic isolation groove 3121.

[0268] In this way, the coil 311 is located in the magnetic isolation groove 3121, the end plate magnetic isolation part 3122 can constrain the magnetic lines of force on the side of the coil 311 away from the other energy transmission assembly 31, the inner ring magnetic isolation part 3123 can constrain the magnetic lines of force on the inner circumferential side of the coil 311, and the outer ring magnetic isolation part 3124 can constrain the magnetic lines of force on the outer circumferential side of the coil 311, thereby greatly constraining the magnetic lines of force and better improving the eddy current influence of the magnetic lines of force on other devices outside the wireless energy transmission structure 30.

[0269] In some embodiments, the end plate magnetic isolation part 3122, the inner ring magnetic isolation part 3123, and the outer ring magnetic isolation part 3124 are integrally formed structures, so as to improve the structural stability of the magnetic isolation member 312 and save the assembly process.

[0270] The magnetic isolation member 312 is made of a magnetic isolation material. For example, the manufacturing material of the magnetic isolation member 312 includes but is not limited to ferrite, nanocrystalline, non-nanocrystalline, soft magnetic body, etc. The soft magnetic body is similar to ferrite powder added to rubber or plastic to form a magnetic isolation effect.

[0271] The connection between the coil 311 and the magnetic isolation member 312 can be adhesive connection, clamping connection, locking member connection, etc.

[0272] In some embodiments, the energy transmission assembly 31 further includes a first encapsulation layer 313 located in the magnetic isolation groove 3121 and connecting the coil 311 and the magnetic isolation member 312. The first encapsulation layer 313 can be a glue layer, and the connection between the coil 311 and the magnetic isolation member 312 can be realized by a glue pouring method. The glue layer can be deformed adaptively according to the shapes of the coil 311 and the magnetic isolation member 312, so as to improve the connection reliability of the coil 311 and the magnetic isolation member 312.

[0273] When assembling the coil 311 and the magnetic isolation member 312, the glue can be poured into the magnetic isolation groove 3121 of the magnetic isolation member 312 first, and then the coil 311 can be placed in the magnetic isolation groove 3121. Alternatively, the coil 311 can be placed in the magnetic isolation groove 3121 first, and then glue can be poured into the magnetic isolation groove 3121. The order of pouring the glue to form the first encapsulation layer 313 is not limited in the embodiments of the present application.

[0274] In some embodiments, the first encapsulation layer 313 includes at least one of a first encapsulation part 3131, a second encapsulation part 3132, and a third encapsulation part 3133. The first encapsulation part 3131 is located in the magnetic isolation groove 3121 and connects the bottom wall of the magnetic isolation groove 3121 and the coil 311. The second encapsulation part 3132 is located in the magnetic isolation groove 3121 and connects the peripheral wall of the magnetic isolation groove 3121 and the coil 311. The third encapsulation part 3133 is located in the magnetic isolation groove 3121 and is located on the side of the coil 311 close to the other energy transmission component 31. The third encapsulation part 3133 covers the coil 311 and connects the magnetic isolation member 312 and the coil 311.

In actual operation, the first encapsulation layer 313 can be designed to include at least one of the first encapsulation part 3131, the second encapsulation part 3132, and the third encapsulation part 3133 according to actual needs.

[0276] It should be noted that, since the third encapsulation part 3133 is located on the side of the coil 311 close to the other energy transmission component 31, it can seal the opening of the magnetic isolation groove 3121 and cover the coil 311, thereby improving the influence of lint, high temperature and high humidity, etc. on the service life of the coil 311 and improving the reliability of the coil 311.

[0277] In the embodiments of the present application, the first encapsulation layer 313 includes the first encapsulation part 3131, the second encapsulation part 3132, and the third encapsulation part 3133, which wraps the coil 311 to better improve the influence of lint, high temperature and high humidity, etc. on the service life of the coil 311 and improve the reliability of the coil 311.

[0278] In assembling the coil 311 and the magnetic isolation member 312, glue can be first filled in the magnetic isolation groove 3121 of the magnetic isolation member 312, and then the coil 311 is placed in the magnetic isolation groove 3121, so that the bottom wall and the peripheral wall of the coil 311 are both glued to form the first encapsulation part 3131 and the second encapsulation part 3132. Then, glue is continuously filled into the magnetic isolation groove 3121 so that the side of the coil 311 close to the other energy transmission component 31 is also glued to form the third encapsulation part 3133.

[0279] In some embodiments, the energy transmission component 31 further includes a mounting shell 314 connected to the magnetic isolation member 312. The mounting shell 314 is configured to achieve the mounting and fixing of the energy transmission component 31 relative to the clothes containing drum 20 or the cabinet 10. The receiving energy transmission component 31b is fixed relative to the clothes containing drum 20 through the mounting shell 314 thereof, and the transmitting energy transmission component 31a is fixed relative to the cabinet 10 through the mounting shell 314 thereof.

[0280] The magnetic isolation member 312 is made of a magnetic isolation material and has a relatively fragile structure. Therefore, the mounting shell 314 is designed to connect the magnetic isolation member 312 and fix the energy transmission assembly 31 relative to the clothes containing drum 20 or the cabinet 10, which is conducive to improving the stability of the installation of the energy transmission assembly 31 on the clothes containing drum 20 or the cabinet 10. In addition, the mounting shell 314 can separate the magnetic isolation member 312 from the clothes containing drum 20 or the cabinet 10, thereby reducing the influence of high temperature of the clothes containing drum 20 or the cabinet 10 on the magnetic isolation member 312.

[0281] In some embodiments, the mounting shell 314 can be made of plastic, metal (such as aluminum), etc., which has the characteristics of high structural strength and high temperature resistance.

The outer ring shell 3145 is connected to the end shell 3143 and is located at the periphery of the inner ring shell 3144. The outer ring shell 3145 is spaced apart from the inner ring shell 3144, and the mounting groove 3141 is formed between the outer ring shell 3145, the inner ring shell 3144, and the end shell 3143.

[0284] In some embodiments, the end shell 3143, the inner ring shell 3144, and the outer ring shell 3145 are integrally formed, which can improve the structural stability of the mounting shell 314 and save assembly process.

[0285] In some embodiments, the mounting shell 314 is fixed relative to the clothes containing drum 20 or the cabinet 10 by at least one of the end shell 3143, the inner ring shell 3144, and the outer ring shell 3145. In other embodiments, the mounting shell 314 further includes a connecting seat 3142, and the mounting shell 314 is fixed relative to the clothes containing drum 20 or the cabinet 10 by the connecting seat 3142. The connecting seat 3142 can be located on the outer side of the outer ring shell 3145 and connected to the outer ring shell 3145, or located on the inner side of the inner ring shell 3144 and connected to the inner ring shell 3144. The specific position of the connecting seat 3142 can be adjusted adaptively according to the internal space layout of the clothes treatment apparatus 1.

[0286] In the embodiments of the present application, referring to FIGS. 19 and 20, the connecting seat 3142 of the transmitting energy assembly 31a is located outside the outer ring shell 3145 and connected to the outer ring shell 3145.

[0290] In the embodiments of the present application, in the energy assembly 31 (the transmitting energy assembly 31a and the receiving energy assembly 31b), the coil 311 and the magnetic isolation member 312 are connected through the first encapsulation layer 313, and the magnetic isolation member 312 and the mounting shell 314 are connected through the second encapsulation layer 315, so that the energy assembly 31 can form a modular structure, which is beneficial to the mounting and fixing of the energy assembly 31 relative to the clothes containing drum 20 or the cabinet 10.

[0291] In some embodiments, referring to FIG. 15, the transmitting energy assembly 31a and the receiving energy assembly 31b are both located outside the clothes containing drum 20 to avoid contact with the load such as clothes in the clothes containing drum 20, thereby improving the safety.

[0292] In some embodiments, referring to FIG. 16, the cabinet 10 includes a back plate 11, and the transmitting energy assembly 31a is mounted on one side of the back plate 11 close to the clothes containing drum 20.

[0293] In some embodiments, the transmitting power transmitting component 31a can be located at a position corresponding to the central region of the back end cover 202 of the clothes containing drum 20. In this case, the back plate 11 can be a metal piece, and the design of the magnetic field shielding component 312 can improve the eddy current effect of the magnetic field lines generated by the magnetic-electric conversion of the wireless power transmitting structure 30 on the back plate 11.

[0294] In some embodiments, referring to FIG. 17, the clothes containing drum 20 includes a drum body 201 and a back end cover 202. The front side of the drum body 201 has a clothes feeding opening, and the back end cover 202 closes the back end opening of the drum body 201. The receiving power transmitting component 31b can be arranged on the side of the back end cover 202 away from the drum body 201.

[0295] In some embodiments, the receiving power transmitting component 31b can be located at the central region of the back end cover 202.

[0296] In some embodiments, along the depth direction of the clothes containing drum 20, the projection of the transmitting power transmitting component 31a and the projection of the receiving power transmitting component 31b at least partially overlap. For example, referring to FIG. 18, the transmitting power transmitting component 31a is aligned with the receiving power transmitting component 31b.

[0297] In some embodiments, along the depth direction of the clothes containing drum 20, the projection of the coil 311 of the transmitting power transmitting component 31a and the projection of the coil 311 of the receiving power transmitting component 31b at least partially overlap. For example, the coil 311 of the transmitting power transmitting component 31a is aligned with the coil 311 of the receiving power transmitting component 31b, which improves the electromagnetic energy received by the receiving power transmitting component 31b.

[0298] In some embodiments, referring to FIG. 25, which is a circuit block diagram of the clothes treating apparatus 1 provided in the embodiments of the present application, in combination with FIG. 25, the clothes treating apparatus 1 further includes a power consuming component 52 and a first control board 51. The power consuming component 52 is fixed relative to the clothes containing drum 20, and the first control board 51 is fixed relative to the clothes containing drum 20. The first control board 51 is integrated with a receiving control circuit and a power consuming component control circuit. The receiving control circuit is electrically connected with the receiving power transmitting component 31b, and the power consuming component control circuit is electrically connected with the power consuming component 52. In this way, the receiving power transmitting component 31b can supply power to the power consuming component 52, so as to maintain the power required for the operation of the power consuming component 52. The power consuming component 52 can be a humidity sensor, and the like, which is not limited in this regard. The design of integrating the receiving control circuit and the power consuming component control circuit on the first control board 51 is beneficial to reducing the manufacturing cost of the clothes treating apparatus 1 and saving the assembly process.

[0299] Since the receiving power transmitting component 31b, the power consuming component 52, and the first control board 51 are all fixed relative to the clothes containing drum 20 and can move synchronously with the clothes containing drum 20, the wiring between the receiving power transmitting component 31b and the first control board 51 and the wiring between the power consuming component 52 and the first control board 51 will not be entangled, and the like.

[0300] The aforementioned electrical component 52 is fixed relative to the clothes drawer 20. It can be either the electrical component 52 mounted on the clothes drawer 20 or a structural component mounted on the clothes drawer 20; there is no limitation in this regard. The aforementioned first control board 51 is fixed relative to the clothes drawer 20. It can be either the first control board 51 mounted on the clothes drawer 20 or a structural component mounted on the clothes drawer 20; there is no limitation in this regard.

[0301] In some embodiments, the garment handling device 1 further includes lifting ribs 4, which are installed inside the garment drum 20. The lifting ribs 4 follow the rotation of the garment drum 20 to actively contact and closely adhere to the garments inside the drum 20, causing the garments to undergo complex movements as the drum 20 rotates. Specifically, propelled by the lifting ribs 4, the garments undergo a process of slowly rising from the bottom to the top, and then, under the combined action of gravity and centrifugal force, naturally slide back to the bottom. This repeated cycle of rising and falling not only allows the garments to continuously change their position within the garment drum 20, but also ensures that every corner of the garments receives even washing or drying treatment, thereby achieving optimal cleaning or drying results.

[0302] In some embodiments, a mounting cavity (not shown in the figure) is defined between the lifting rib 4 and the clothes container 20, and the first control plate 51 is located in the mounting cavity. This can improve the concealment of the first control plate 51 and prevent the first control plate 51 from interfering with the clothes in the clothes container 20.

[0303] In some embodiments, the garment processing device 1 further includes a second control board 71, which is fixed relative to the housing 10. The second control board 71 integrates a power supply circuit and a transmission control circuit, and the transmission control circuit is electrically connected to the transmission power transfer component 31a. Designing the second control board 71 to integrate the power supply circuit and the transmission control circuit helps to reduce the manufacturing cost of the garment processing device 1 and saves assembly time.

[0304] The second control board 71 is fixed relative to the housing 10. It can be a structural component that is mounted on the housing 10 or a component that is mounted on the housing 10. There is no limitation on this.

[0305] In some embodiments, the second control board 71 is located outside the housing 10 and outside the air duct, which can avoid the influence of high temperature and humidity inside the clothing processing equipment 1, and facilitate the disassembly and maintenance by staff.

[0306] In some embodiments, the clothes treating apparatus 1 further comprises a driving device, which can be a motor or the like, as a power source of the whole apparatus, to enable the clothes containing drum 20 to rotate or swing. Such dynamic movement mode not only helps the clothes to be evenly tumbled in the drum, improving the uniformity of washing and drying, but also effectively avoids the clothes from being entangled or locally over-worn, protecting the fabric of the clothes.

[0307] In some embodiments, the clothes treating apparatus 1 further comprises a heat exchange assembly, and a circulating air duct is formed in the cabinet 10 to provide a circulating air flow repeatedly flowing through the clothes containing drum 20. The heat exchange assembly is arranged to exchange heat with the air flow in the circulating air duct, thereby dehumidifying and heating. The humid and hot air flow in the clothes containing drum 20 can enter the circulating air duct through the air outlet, and be converted into a dry and hot air flow after heat exchange with the heat exchange assembly, and the dry and hot air flow is returned to the clothes containing drum 20.

[0308] In some embodiments, the heat exchange assembly comprises a condenser and an evaporator, and the clothes treating apparatus 1 further comprises a compressor and a throttling device, and the compressor, the condenser, the throttling device and the evaporator are connected by pipelines to form a heat pump system, and a refrigerant can circulate in the heat pump system. The air flow in the circulating air duct exchanges heat with the refrigerant in the evaporator and the condenser to form a dry and hot air flow. The evaporator is arranged to cool and dehumidify the humid and hot air flow from the clothes containing drum 20 into a dry and cold air flow; and the condenser heats the dry and cold air flow into a dry and hot air flow to return to the clothes containing drum 20.

[0309] The working principle of the heat pump system is as follows: the compressor sucks in low-pressure gaseous refrigerant and compresses it into high-pressure discharge; the high-pressure refrigerant discharged into the condenser transfers heat to the air flow to condense into high-pressure liquid; the high-pressure liquid refrigerant flows through the throttling device to reduce pressure and becomes a low-pressure low-temperature gas-liquid two-phase mixture into the evaporator; the refrigerant in the evaporator absorbs the heat of the air flow to become low-pressure gas; the low-pressure gas is sucked into the compressor again; such a cycle is repeated to realize heat exchange. That is, the evaporator is arranged to cool and dehumidify the humid and hot air flow from the clothes containing drum 20 into a dry and cold air flow, and the condenser heats the dry and cold air flow into a dry and hot air flow to return to the clothes containing drum 20. The dry and hot air flow returned to the clothes containing drum 20 contacts the damp clothes again to form a humid and hot air flow again, completing a drying cycle. By repeatedly running the drying cycle, a circulating air flow is continuously provided to the clothes containing drum 20 to dry the clothes.

[0310] For example, the evaporator and the condenser can both be finned tube or micro-channel heat exchangers.

[0311] For example, the throttling device includes but is not limited to an electronic expansion valve or the like.

[0312] In an embodiment, the clothes treating apparatus 1 comprises a fan wheel configured to drive the air flow. For example, the fan wheel is located in the circulating air duct and between the heat exchange assembly and the return air inlet. During the drying process, the fan wheel is configured to drive the air flow through the clothes to sequentially pass through the evaporator and the condenser, and then blow to the clothes to form the circulating air. The fan wheel can accelerate the air flow and improve the drying efficiency.

[0313] The above merely provides the optional embodiments of the present application, and does not limit the patent scope of the present application. Any equivalent structure transformation made by using the content of the present application and the drawings, or direct / indirect application in other related technical fields, shall be included in the patent protection scope of the present application.
