Without more limitations, the element defined by the statement "comprising" does not exclude the presence of other identical elements in the process, method, article or apparatus including the element. "Multiple" means the number is greater than or equal to two.

[0035] In the embodiments of the present application, the type of the clothes treatment apparatus is not limited, which can be a clothes dryer or a washer-dryer, etc., which is not limited herein. Exemplarily, the clothes treatment apparatus in the embodiments of the present application is taken as a clothes dryer for illustration.

[0036] Please refer to Figure 1 , the clothes treatment apparatus includes a cabinet 11 and a clothes treatment drum 10, and the clothes treatment drum 10 is rotatably arranged in the cabinet 11.

[0037] The cabinet 11 is used to accommodate the clothes treatment drum 10 and other structural members, and the cabinet 11 serves as an appearance component of the clothes treatment apparatus and protects the clothes treatment drum 10.

[0038] The clothes treatment drum 10 is rotatably arranged in the cabinet 11, and the clothes treatment drum 10 has a clothes treatment cavity 10a, which can be used to place and dry clothes, and the clothes treatment drum 10 can drive the clothes to rotate.

[0039] Exemplarily, taking a drum-type clothes drying machine as an example, the rotation axis P of the clothes processing drum 10 is along the horizontal direction, and the front side of the clothes processing drum 10 has a clothes feeding opening which is in communication with the clothes processing cavity 10a, and a user feeds or takes out the clothes processing cavity 10a through the clothes feeding opening. During the rotation of the clothes processing drum 10, the clothes are moved from the lower side to the upper side, and the clothes fall from the upper side to the lower side under the action of gravity, so that the clothes are dispersed, beaten and changed in posture under the joint action of the clothes processing drum 10 and gravity.

[0040] Please refer to Figure 1 , the clothes processing drum 10 can be a single drum structure, that is, the clothes processing equipment has only one drum body, that is, the clothes processing drum 10.

[0041] In other examples, the clothes processing equipment can also include an outer drum which is arranged on the circumferential outer side of the clothes processing drum 10.

[0042] The embodiments of the present application are described taking the clothes processing equipment with a single drum structure as an example.

[0043] Exemplarily, the clothes processing drum 10 is substantially in a hollow cylindrical shape. The clothes processing drum 10 can be made of metal material, for example, stainless steel material, etc., which is not limited here.

[0044] It should be noted that, unless otherwise stated, in the embodiments of the present application, the axial direction refers to the extension direction of the rotation axis P of the clothes processing drum 10, and the radial direction is perpendicular to the axial direction.

[0045] Please refer to Figures 1 to 7 , the embodiments of the present application provide a clothes processing equipment, which includes a clothes processing drum 10, a transmitting module 12 and a receiving module 13.

[0046] The clothes processing drum 10 has a clothes processing cavity 10a. The transmitting module 12 includes a transmitting coil 121. The receiving module 13 is arranged on the clothes processing drum 10, and the receiving module 13 includes a receiving coil 131 which is used for receiving the electromagnetic signal transmitted by the transmitting coil 121 and generating an induced current; at least one of the transmitting coil 121 and the receiving coil 131 includes a plurality of stacked coil monomers 40.

[0047] The transmitting module 12 can be arranged on a component other than the clothes processing drum 10. It should be noted that the component other than the clothes processing drum 10 refers to a component which is independent of the clothes processing drum 10 and is arranged on the outer side of the clothes processing drum 10, and the component other than the clothes processing drum 10 can remain stationary when the clothes processing drum 10 rotates, so that the transmitting module 12 can remain stationary, for example, the component other than the clothes processing drum 10 can be a cabinet 11 or a base arranged below the clothes processing drum 10, etc., which is not limited here.

[0048] The receiving module 13 is not limited to be arranged at a position of the laundry treatment drum 10. For example, the receiving module 13 can be arranged at any side wall of the laundry treatment drum 10, such as a circumferential side wall of the laundry treatment drum 10, or a rear side wall of the laundry treatment drum 10 facing the rear side, and the like.

[0049] The receiving coil 131 is configured to receive the electromagnetic signal transmitted by the transmitting coil 121 and generate an induced current. Specifically, the transmitting coil 121 generates a varying magnetic field, and the receiving coil 131 generates an induced current by electromagnetic induction, receives the power transmission from the transmitting coil 121, and outputs the electric energy. The transmitting coil 121 and the receiving coil 131 achieve power transmission by electromagnetic induction, that is, the transmitting coil 121 can wirelessly transmit electric power to the receiving coil 131.

[0050] At least one of the transmitting coil 121 and the receiving coil 131 includes a plurality of stacked coil units 40. For example, 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, or both the transmitting coil 121 and the receiving coil 131 can include a plurality of stacked coil units 40.

[0051] For example, in some embodiments, the transmitting coil 121 can include only a single layer of coil units 40, and the receiving coil 131 can include a plurality of stacked coil units 40. In other embodiments, the receiving coil 131 can include only a single layer of coil units 40, and the transmitting coil 121 can include a plurality of stacked coil units 40. In yet other embodiments, both the transmitting coil 121 and the receiving coil 131 can include a plurality of stacked coil units 40.

[0052] In embodiments where both the transmitting coil 121 and the receiving coil 131 include a plurality of stacked coil units 40, the number of layers of coil units 40 of the transmitting coil 121 and the number of layers of coil units 40 of the receiving coil 131 can be the same or different.

[0053] The coil unit 40 has a substantially flat structure, that is, the thickness dimension of the coil unit 40 is smaller than the dimension of the first direction perpendicular to the thickness direction, and the appearance shape is substantially flat.

[0054] The plurality of coil units 40 can be stacked without increasing the dimension of the coil unit 40 along the first direction (i.e., the direction perpendicular to the thickness direction of the coil unit 40), thereby increasing the number of turns of the transmitting coil 121 and / or the receiving coil 131.

[0055] It can be understood that the multi-layer stacked coil monomers 40 can be connected, for example, the multi-layer coil monomers 40 of the transmitting coil 121 can be connected in series. For another example, the multi-layer coil monomers 40 of the receiving coil 131 can be connected in series.

[0056] The transmitting coil 121 is wirelessly connected with 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 treatment drum 10 can be electrically connected with the receiving module 13, for example, the receiving coil 131, and the electrical element is powered by the receiving coil 131 to meet the power demand.

[0057] It should be noted that the electrical element can be a structural member capable of achieving an electrical function and / or used in a circuit to achieve at least one electrical function. The number of electrical elements can be one, two, three or more.

[0058] The electrical element can be a unit for detecting the state of the clothes and other units capable of having a specific function to improve the drying performance. For example, the unit for detecting the state of the clothes can be a unit for detecting the temperature, conductivity, etc. of the clothes.

[0059] For example, the receiving coil 131 is arranged in the clothes treatment drum 10, and the electrical element, such as the unit for detecting the state of the clothes, can be arranged in the clothes treatment drum 10 and electrically connected with the receiving module 13 to obtain electrical energy. When the clothes treatment drum 10 rotates, the receiving module 13 and the electrical element rotate synchronously, the electrical connection between the receiving coil 131 and the electrical element is relatively stable, and the receiving coil 131 can also receive the electrical energy transmitted from the transmitting coil 121 in the rotating process. In this way, the electrical element arranged in the clothes treatment drum 10 can be close to the clothes to detect the state of the clothes and perform a specific function to improve the working performance of the clothes treatment device. For example, the drying performance of the clothes treatment device can be improved.

[0060] The clothes processing device provided in the embodiments of the present application can transmit electric energy without contact between the transmitting module 12 and the receiving module 13, and can realize electric energy transmission without wire connection, and has high reliability. The receiving module 13 is arranged in the clothes processing cylinder 10, and the receiving module 13 can receive electric energy and / or signals emitted by the transmitting module 12, so that the electric appliance element can be arranged in the clothes processing cylinder 10, and the receiving module 13 can supply power to the electric appliance element to meet the power demand of the electric appliance element, reduce the assembly difficulty of the electric appliance element, and improve the overall performance of the clothes processing device. The multiple-layer coil monomers 40 can increase the number of turns of the transmitting coil 121 and / or the receiving coil 131, and the multiple-layer coil monomers 40 can increase the transmission power of the transmitting coil 121 and / or the receiving coil 131, so that the power range that can be transmitted by the transmitting coil 121 and / or the receiving coil 131 can be improved, which can meet the requirements of the installation size of the transmitting coil 121 and / or the receiving coil 131 in a narrow space and can meet the power demand.

[0061] It should be noted that in some examples, the transmitting module 12 and the receiving module 13 can not only transmit electric energy, but also can realize signal transmission. That is, the clothes information detected by the electric appliance element can be transmitted to the receiving module 13, and the receiving module 13 can transmit the clothes information to the transmitting module 12.

[0062] Of course, in another embodiment, the transmitting module 12 and the receiving module 13 can only transmit electric energy, and the clothes processing device can be provided with a wireless transmission unit, the receiving module 13 can provide electric energy for the wireless transmission unit, and the wireless transmission unit can receive the clothes information detected by the electric appliance element and perform wireless transmission.

[0063] In some embodiments, the transmitting coil 121 includes multiple-layer stacked coil monomers 40, the receiving coil 131 includes single-layer coil monomers 40, and the projection area of the receiving coil 131 is greater than the projection area of the transmitting coil 121 in a plane perpendicular to the thickness direction of the coil monomer 40.

[0064] In this embodiment, the projection area of the receiving coil 131 is greater than the projection area of the transmitting coil 121, the size of the receiving coil 131 is relatively large, and the receiving coil 131 can have relatively large output power, and the transmitting coil 121 includes multiple-layer stacked coil monomers 40, and the number of coil monomers 40 can be increased to improve the transmitting power, so that the transmitting coil 121 and the receiving coil 131 can both improve their respective power, thereby meeting the power demand of the electric appliance element with relatively large power.

[0065] In some embodiments, referring to Figure 2 , the coil monomer 40 has a hollow ring structure. Specifically, the projection of the coil monomer 40 is in a ring shape in a plane perpendicular to the thickness direction of the coil monomer 40. In this way, the electromagnetic field can be limited near the core.

[0066] As an example, please refer to Figure 2 The center of the coil monomer 40 remains a hollow space, and the cable is spirally wound in the plane to form a hollow annular structure.

[0067] Exemplarily, the transmitting coil 121 can be in a hollow annular structure; or, the receiving coil 131 can be in an annular structure, or, both the transmitting coil 121 and the receiving coil 131 can be in an annular structure.

[0068] In some embodiments, the coil monomer 40 is in a non-annular structure. Specifically, taking a plane perpendicular to the thickness direction of the coil monomer 40 as a projection plane, the projection of the coil monomer 40 is in a non-annular shape. The non-annular structure refers to a structure without a hollow space. As an example, the center of the coil monomer 40 does not have a hollow space, and the cable is spirally wound in the plane to form a non-annular structure.

[0069] Exemplarily, the transmitting coil 121 can be in a non-annular structure; or, the receiving coil 131 can be in a non-annular structure, or, both the transmitting coil 121 and the receiving coil 131 can be in a non-annular structure.

[0070] In some embodiments, the transmitting coil 121 is in an annular structure, and the receiving coil 131 is in a non-annular structure.

[0071] Exemplarily, the transmitting coil 121 is in an annular structure, and the transmitting coil 121 includes a plurality of coil monomers 40 stacked in layers, the receiving coil 131 is in a non-annular structure, and the receiving coil 131 includes a single layer of coil monomers 40, taking a plane perpendicular to the thickness direction of the coil monomer 40 as a projection plane, the projection area of the receiving coil 131 is greater than the projection area of the transmitting coil 121.

[0072] In this embodiment, the transmitting coil 121 is in an annular structure, which can avoid structures such as a support shaft to meet installation requirements; the receiving coil 131 is in a non-annular structure, which can increase the area of the receiving coil 131 to improve the power.

[0073] In some embodiments, please refer to Figure 1 and Figure 7 The laundry treating apparatus includes a cabinet 11, a laundry treating tub 10 rotatably provided in the cabinet 11, and a transmitting module 12 provided in the cabinet 11.

[0074] As an example, the transmitting module 12 can be electrically connected with a main control board of the clothes treatment apparatus. The main control board is arranged in the cabinet 11, and is configured to control the operation of the clothes treatment apparatus and supply power to various parts in the clothes treatment apparatus so that the parts can work normally to realize the functions such as the clothes drying control. As an example, the transmitting module 12 is electrically connected with the main control board through a wire to receive the power supplied by the main control board. The transmitting module 12 is arranged in the cabinet 11 and kept in a static state so as to stably receive the power from the main control board and increase the reliability of the electrical connection between the transmitting module 12 and the main control board.

[0075] In this embodiment, the cabinet 11 can provide more positions for installing the transmitting module 12, and the cabinet 11 is kept in a static state to facilitate the transmitting module 12 to receive the power from the main control board or other structural members.

[0076] In some embodiments, the transmitting module 12 can be arranged on the top plate of the cabinet 11. The top plate refers to the part of the cabinet 11 facing upward. It can be understood that the transmitting module 12 can also be arranged at other positions of the cabinet 11.

[0077] In some embodiments, referring to Figures 1 to 7 , the cabinet 11 comprises a back plate 111, the clothes treatment drum 10 comprises a back cover 102 and a drum body 101, the back cover 102 is arranged at the rear end of the drum body 101 to jointly define a clothes treatment cavity 10a, the receiving module 13 is arranged on the side of the back cover 102 facing the back plate 111, and the transmitting module 12 is arranged on the side of the back plate 111 facing the back cover 102.

[0078] The back plate 111 refers to the part of the cabinet 11 located at the rear side of the clothes treatment apparatus along the front-rear direction. The rear side refers to the side of the clothes treatment apparatus away from the user after installation. The back plate 111 is located at the rear side of the clothes treatment drum 10.

[0079] The front side of the drum body 101 is open to form a clothes feeding opening.

[0080] The receiving module 13 is arranged on the side of the back cover 102 facing the back plate 111, i.e., the receiving module 13 is arranged at the rear side of the back cover 102.

[0081] The transmitting module 12 is arranged on the side of the back plate 111 facing the back cover 102, i.e., the transmitting module 12 is arranged at the front side of the back plate 111.

[0082] In this embodiment, the receiving module 13 is arranged on the side of the back cover 102 facing the back plate 111, and the transmitting module 12 is arranged on the side of the back plate 111 facing the back cover 102. The distance between the transmitting module 12 and the receiving module 13 is relatively short, which increases the reliability of power transmission.

[0083] In some embodiments, the rear end of the barrel 101 can be detachably or non-detachably connected with the rear cover 102.

[0084] In some embodiments, the receiving module 13 can be arranged on the side of the rear cover 102 away from the rear plate 111, i.e. the receiving module 13 is arranged on the front side of the rear cover 102.

[0085] In some embodiments, the transmitting module 12 can be arranged on the side of the rear plate 111 away from the rear cover 102, i.e. the transmitting module 12 is arranged on the rear side of the rear plate 111.

[0086] In some embodiments, referring to Figures 1 to 7 The receiving coil 131 and the transmitting coil 121 are arranged opposite to each other along the axial direction of the clothes treatment barrel 10, and the multi-layer coil units 40 are stacked along the axial direction of the clothes treatment barrel 10.

[0087] For example, the receiving coil 131 can include the multi-layer coil units 40 stacked along the axial direction, or the transmitting coil 121 can include the multi-layer coil units 40 stacked along the axial direction; or both the receiving coil 131 and the transmitting coil 121 can include the multi-layer coil units 40 stacked along the axial direction.

[0088] The receiving coil 131 and the transmitting coil 121 are arranged opposite to each other along the axial direction of the clothes treatment barrel 10, which means that the receiving coil 131 and the transmitting coil 121 are spaced apart along the axial direction, and the projection of the transmitting coil 121 overlaps at least part of the projection of the receiving coil 131 in a projection plane perpendicular to the axial direction.

[0089] In this embodiment, the receiving coil 131 and the transmitting coil 121 are arranged opposite to each other along the axial direction of the clothes treatment barrel 10, for example, the transmitting coil 121 and the receiving coil 131 can be coaxial and opposite to each other at all times, i.e. no matter where the clothes treatment barrel 10 is rotated to, the transmitting coil 121 and the receiving coil 131 are always coaxial and opposite to each other. For another example, the transmitting coil 121 and the receiving coil 131 can be coaxial and opposite to each other at a set position, i.e. the receiving coil 131 can be moved to the set position coaxial and opposite to the transmitting coil 121 by rotating the clothes treatment barrel 10. In this way, the influence of the rotating clothes treatment barrel 10 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 the multi-layer coil units 40 stacked along the axial direction, which can make full use of the axial spacing between the clothes treatment barrel 10 and the cabinet 11, 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.

[0090] In some embodiments, the transmitting coil 121, the receiving coil 131 and the clothes treatment barrel 10 are coaxial.

[0091] The projection of the transmitting coil 121 and the projection of the receiving coil 131 are coaxial annular structures in a plane perpendicular to the axial direction.

[0092] In this embodiment, the receiving coil 131 and the transmitting coil 121 can always maintain a relative state during the rotation of the laundry treatment drum 10, regardless of the position of the receiving coil 131 in the laundry treatment drum 10. This 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 element of the laundry treatment drum 10. That is, the receiving coil 131 can always effectively and sufficiently supply power to the electric appliance element during the rotation of the laundry treatment drum 10, without the need for additional auxiliary power supply structure, thereby increasing the power supply reliability of the laundry treatment device.

[0093] In some embodiments, the laundry treatment device comprises an electric appliance element, and at least one electric appliance element is arranged in the laundry treatment cavity 10a, and the receiving coil 131 is electrically connected to the electric appliance element.

[0094] For example, one, two or more electric appliance elements can be arranged in the laundry treatment cavity 10a.

[0095] The receiving coil 131 is electrically connected to the electric appliance element, and the receiving coil 131 can supply power to the electric appliance element. The receiving coil 131 and the electric appliance element can be electrically connected through a conductive wire bundle 30, or the receiving coil 131 and the electric appliance element can be wirelessly connected without the conductive wire bundle 30.

[0096] In this embodiment, at least one electric appliance element is arranged in the laundry treatment cavity 10a, and the electric appliance element arranged in the laundry treatment cavity 10a can closely sense the state of the laundry and perform specific functions, thereby improving the working performance of the laundry treatment device.

[0097] In some embodiments, referring to Figure 1 and Figure 8 , the laundry treatment device comprises a lifting rib 14 arranged on the circumferential surface of the laundry treatment cavity 10a, and at least part of the at least one electric appliance element is arranged on the lifting rib 14.

[0098] The lifting rib 14 protrudes radially from the circumferential surface of the laundry treatment cavity 10a. Specifically, the lifting rib 14 can contact the laundry in the laundry treatment cavity 10a and drive the laundry to rotate with the laundry treatment drum 10. For example, the laundry moves upward under the action of the lifting rib 14, and then moves downward under the action of gravity and centrifugal force, and so on. In this way, the laundry continuously changes its posture in the laundry treatment cavity 10a.

[0099] In this embodiment, at least part of the at least one electric element is arranged in the lifting rib 14, and the lifting rib 14 can provide a mounting position for the at least one electric element.

[0100] In some embodiments, the at least one electric element is arranged inside the lifting rib 14.

[0101] For example, one electric element can be arranged inside the lifting rib 14, or a plurality of electric elements can be arranged inside the lifting rib 14.

[0102] In this embodiment, the lifting rib 14 is used to protect the electric element arranged inside the lifting rib 14, and to reduce the probability of the electric element arranged inside the lifting rib 14 contacting the clothes.

[0103] In some embodiments, the at least one electric element is arranged on the outer surface of the lifting rib 14.

[0104] For example, one electric element can be arranged on the outer surface of the lifting rib 14, or a plurality of electric elements can be arranged on the outer surface of the lifting rib 14.

[0105] In this embodiment, some electric elements need to contact the clothes to detect the parameters of the clothes and generate clothes information, so as to complete the detection of the clothes. The lifting rib 14 is used to contact and drive the clothes to rotate. Arranging this type of electric element on the outer surface of the lifting rib 14 can increase the contact area and time with the clothes, thereby improving the detection accuracy.

[0106] In some embodiments, referring to Figure 1 and Figure 8 , the electric element includes a detection unit 15, and the detection unit 15 is used to detect the parameters of the clothes in the clothes treatment cavity 10a.

[0107] For example, the parameters of the clothes include, but are not limited to, the temperature and / or the electrical conductivity of the clothes, etc.

[0108] For example, the detection unit 15 can be arranged on the lifting rib 14. In this way, the detection unit 15 is convenient to contact the clothes.

[0109] For example, when the parameter of the clothes is the electrical conductivity, the clothes treatment device 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 or the like load in the clothes treatment cavity 10a contacts 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 or the like loads with different moisture levels are different, that is, the moisture level of the clothes or the like load is related to the electrical conductivity, and the drying degree is determined according to the electrical conductivity.

[0110] In this embodiment, the detection unit 15 is one of the electrical 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 10a, the detection electrode 151 of the detection unit 15 can be in contact with the load such as clothes in the clothes treatment cavity 10a, so as to perceive the drying degree of the clothes in close proximity, and effectively improve the accuracy of judging the drying degree of the load such as clothes in the clothes treatment cavity 10a.

[0111] In some embodiments, referring to Figure 8 The detection unit 15 includes the detection electrode 151, which can be arranged on the outer surface of the lifting rib 14.

[0112] In this embodiment, the detection electrode 151 is arranged on the outer surface of the lifting rib 14, which facilitates close contact with the load such as clothes.

[0113] For example, the detection electrode 151 can be located on one outer surface of the lifting rib 14 in the circumferential direction, and the other part is located on the top side of the lifting rib 14 away from the circumferential side wall of the clothes treatment cylinder 10 in the radial direction.

[0114] The specific structure of the detection electrode 151 is not limited.

[0115] 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 lifting rib 14. 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.

[0116] 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 an electrode pair, the detection electrode 151 has at least two electrode pairs, the clothes contact at least two electrode pairs, and 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, so as to be more sensitive to the detection of electrical conductivity changes, improve the detection accuracy and sensitivity of the detection electrode 151, and to a certain extent, reduce the problems of incomplete drying or over-drying, and improve the drying performance.

[0117] In some embodiments, referring to Figures 4 to 6The air inlet passage is adapted to air flow to pass through and enter the laundry treatment cavity 10a. In other words, the air inlet passage communicates with the laundry treatment cavity 10a, and the air flow enters the laundry treatment cavity 10a through the air inlet passage for drying the laundry.

[0118] The air inlet passage is adapted to air flow to pass through and enter the laundry treatment cavity 10a. In other words, the air inlet passage communicates with the laundry treatment cavity 10a, and the air flow enters the laundry treatment cavity 10a through the air inlet passage for drying the laundry.

[0119] The non-air inlet area 120 refers to an area where the air flow cannot pass through and enter the laundry treatment cavity 10a.

[0120] The air inlet area 110 surrounds the outer periphery of the non-air inlet area 120, that is, the air inlet area 110 encloses the non-air inlet area 120.

[0121] The at least part of the projection of the receiving coil 131 located in the non-air inlet area 120 means that part of the projection of the receiving coil 131 can be located in the non-air inlet area 120, or the entire projection of the receiving coil 131 can be located in the non-air inlet area 120.

[0122] In this embodiment, the at least part of the projection of the receiving coil 131 located in the non-air inlet area 120 facilitates the fixed connection of the receiving module 13 and the non-air inlet area 120, and can also reduce the obstruction of the receiving coil 131 to the air flow.

[0123] The type of the air inlet passage includes, but is not limited to, the air inlet opening 100a or an air inlet hole, etc. The area of the air inlet hole can be smaller than the area of the air inlet opening 100a, and in some cases, the area of the air inlet hole can be much smaller than the area of the air inlet opening 100a, for example, the area of the air inlet opening 100a can be 5 times or more than the area of the air inlet hole. In this way, the air inlet hole can to some extent play a role in blocking the lint.

[0124] In some embodiments, the non-air inlet area 120 can include a core portion 1021, and the air inlet area 110 can include a support arm 1023 and an outer ring structure 1022.

[0125] In some embodiments, referring to Figures 4 to 6 The laundry treatment device includes a bearing 50, and the bearing 50 and the receiving coil 131 are both connected to the end wall 10b of the laundry treatment drum 10. The projection of the receiving coil 131 surrounds the projection of the bearing 50, with a plane perpendicular to the axial direction of the laundry treatment drum 10 as the projection plane.

[0126] Exemplarily, the laundry treating apparatus includes a support shaft, which can be connected with the laundry treating drum 10 through a bearing 50. For example, the support shaft is connected with an inner ring of the bearing 50, and the end wall 10b is connected with an outer ring of the bearing 50. The laundry treating drum 10 rotates relative to the support shaft, and the support shaft can provide a support force for the laundry treating drum 10 and its load. The bearing 50 can reduce the friction loss between the support shaft and the laundry treating drum 10 during the rotation of the laundry treating drum 10, and facilitate the rotation of the laundry treating drum 10 relative to the support shaft.

[0127] The type of the bearing 50 is not limited, and the bearing 50 is a rolling bearing 50, including but not limited to a ball bearing 50, etc.

[0128] In this embodiment, the projection of the receiving coil 131 surrounds the projection of the bearing 50, and the receiving coil 131 has a ring structure and can avoid the bearing 50, so that the receiving coil 131 can rotate with the laundry treating drum 10.

[0129] In some embodiments, referring to Figure 4 and Figure 5 , the end wall 10b forms an air inlet 100a that communicates with the laundry treating cavity 10a, and the air inlet 100a is located on a side of the receiving coil 131 away from the bearing 50.

[0130] It can be understood that the end wall 10b is a side wall of the laundry treating drum 10, for example, the rear cover 102 can have the end wall 10b, and the end wall 10b is part of the rear cover 102.

[0131] 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 100a, and the projection of the receiving coil 131 is located on the inner side of the projection of the air inlet 100a in the radial direction.

[0132] The air inlet 100a is suitable for air flow to enter the laundry treating cavity 10a.

[0133] As an example, the receiving coil 131 is between the bearing 50 and the air inlet 100a, and the distance between the bearing 50 and the air inlet 100a is limited, and the ring width of the receiving coil 131 in the radial direction is limited. The receiving coil 131 can include multiple coil units 40 stacked in the axial direction, so that the transmission power of the receiving coil 131 is increased through the multiple coil units 40 in the case of limited ring width of the receiving coil 131 in the radial direction, 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 the narrow space and meets the requirements of some high-power output.

[0134] In this embodiment, the air inlet 100a 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 100a. On the one hand, the axis of the receiving coil 131 coincides with the axis of the clothes treatment drum 10, so that the receiving coil 131 is coaxially arranged with the clothes treatment drum 10. On the other hand, the bearing 50 and the air inlet 100a can position and limit the receiving module 13, thereby reducing the assembly difficulty and improving the assembly efficiency.

[0135] In some embodiments, referring to Figures 4 to 6 , the end wall 10b includes a core portion 1021, an outer ring structure 1022, and a plurality of support arms 1023. The bearing 50 and the receiving coil 131 are arranged on the core portion 1021, and the outer ring structure 1022 surrounds the outer periphery of the core portion 1021. The plurality of support arms 1023 are spaced apart along the circumferential direction of the core portion 1021, and the support arms 1023 connect the core portion 1021 and the outer ring structure 1022. The core portion 1021, the outer ring structure 1022, and the plurality of support arms 1023 together define a plurality of air inlets 100a, and the plurality of air inlets 100a surround the outer periphery of the receiving coil 131.

[0136] For example, the support arms 1023 can be integrally formed with the core portion 1021 and the outer ring structure 1022. Alternatively, the support arms 1023 can be connected to the core portion 1021 and the outer ring structure 1022 by riveting, welding, screwing, or the like, without limitation.

[0137] In this embodiment, the support arms 1023 connect the core portion 1021 and the outer ring structure 1022 together, so that the end wall 10b, for example, the rear cover 102, has sufficient structural strength and increases the structural stability of the clothes treatment drum 10.

[0138] In some embodiments, referring to Figures 1 to 7 , the clothes treatment device includes a cabinet 11, a ring-shaped sealing element 20, and a conductive wire harness 30. The clothes treatment drum 10 is rotatably arranged in the cabinet 11, and the receiving module 13 is arranged on the end wall 10b of the clothes treatment drum 10. The end wall 10b forms a wire passing opening 10c that communicates with the clothes treatment cavity 10a. The ring-shaped sealing element 20 is arranged between the end wall 10b and the cabinet 11 to achieve dynamic sealing between the end wall 10b and the cabinet 11. The wire passing opening 10c is located on the side of the ring-shaped sealing element 20 close to the rotation axis P of the clothes treatment drum 10. One end of the conductive wire harness 30 is electrically connected to the receiving coil 131, and the other end of the conductive wire harness 30 passes through the wire passing opening 10c and extends into the clothes treatment cavity 10a.

[0139] In some embodiments, referring to Figures 4 to 6The air inlet 100a can be located on the side of the annular seal 20 close to the rotation axis P of the clothes treatment drum 10. Both the wire passing opening 10c and the air inlet 100a can penetrate the end wall 10b.

[0140] The annular seal 20 is arranged between the end wall 10b and the cabinet 11 to realize dynamic sealing between the end wall 10b and the cabinet 11. That is, during rotation of the clothes treatment drum 10 relative to the cabinet 11, the annular seal 20 can realize sealing between the end wall 10b and the cabinet 11. As an example, the annular seal 20 can be fixed to the end wall 10b, and the annular seal 20 is in sealing contact with the cabinet 11. For example, the annular seal 20 can abut against the back plate 111 of the cabinet 11. In this way, the annular seal 20, the end wall 10b and the cabinet 11 together define a sealed passage to facilitate air flow into the air inlet 100a through the sealed passage. In this way, air leakage to the outside of the clothes treatment cavity 10a can be avoided to some extent, and drying efficiency can be improved.

[0141] In a plane perpendicular to the axial direction of the clothes treatment drum 10, the projection of the annular seal 20 is annular. Both the wire passing opening 10c and the air inlet 100a can be located on the side of the annular seal 20 close to the rotation axis P of the clothes treatment drum 10, that is, the wire passing opening 10c and the air inlet 100a are located on the side of the annular seal 20 close to the rotation axis in the radial direction, and the annular seal 20 can surround the air inlet 100a and the wire passing opening 10c.

[0142] The conductive wire bundle 30 is used 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 30.

[0143] The conductive wire bundle 30 penetrates the wire passing opening 10c and extends into the clothes treatment cavity 10a. In this way, the electrical appliance element can be arranged inside the clothes treatment cavity 10a, and the conductive wire bundle 30 can be routed outside the clothes treatment cavity 10a and inside the clothes treatment cavity 10a according to the position requirement of the electrical appliance element.

[0144] If the wire passing opening 10c is located on the side of the annular seal 20 away from the rotation axis in the radial direction, the conductive wire bundle 30 needs to pass through the annular seal 20, and the annular seal 20 abuts against the cabinet 11. During rotation of the clothes treatment drum 10, the annular seal 20 abuts against the cabinet 11 and rotates relative to the cabinet 11. The conductive wire bundle 30 is rubbed during rotation of the annular seal 20, and is prone to damage.

[0145] In the present application, since the wire passing opening 10c is located on the side of the annular seal 20 close to the rotation axis in the radial direction, the conductive wire bundle 30 can not pass through the annular seal 20, and the risk of damage to the wire bundle can be avoided to some extent.

[0146] In this embodiment, the conductive wire bundle 30 passes through the wire passing port 10c and extends into the clothes treatment cavity 10a. The electrical appliance element can be arranged inside the clothes treatment cavity 10a. According to the position requirement of the electrical appliance element, the conductive wire bundle 30 can be routed outside the clothes treatment cavity 10a and inside the clothes treatment cavity 10a, which reduces the routing difficulty of the conductive wire bundle 30. The wire passing port 10c is located on the side of the annular sealing member 20 close to the rotation axis P of the clothes treatment drum 10. The conductive wire bundle 30 can not pass through the annular sealing member 20, which can to some extent avoid the risk of wear of the wire bundle.

[0147] The material of the annular sealing member 20 is not limited. For example, the annular sealing member 20 can include felt. The felt has good wear resistance and elasticity, which can improve the service life and reliability of the annular sealing member 20.

[0148] In some embodiments, the annular sealing member 20 is arranged around the outer ring structure 1022. At least one of the core 1021, the outer ring structure 1022, and the support arm 1023 is provided with a wire passing port 10c.

[0149] The annular sealing member 20 is arranged around the outer ring structure 1022, which means that the annular sealing member 20 extends along the circumference of the outer ring structure 1022 in a ring shape. The annular sealing member 20 can surround the support arm 1023 and the core 1021.

[0150] At least one of the core 1021, the outer ring structure 1022, and the support arm 1023 is provided with a wire passing port 10c, which means that the number of wire passing ports 10c can be one, and one of the core 1021, the outer ring structure 1022, and the support arm 1023 can be provided with a wire passing port 10c. Alternatively, the number of wire passing ports 10c can be two, and two of the core 1021, the outer ring structure 1022, and the support arm 1023 can be provided with a wire passing port 10c. Alternatively, the number of wire passing ports 10c can be three, and all of the core 1021, the outer ring structure 1022, and the support arm 1023 can be provided with a wire passing port 10c. It can be understood that the number of wire passing ports 10c can also be greater than three, which is not limited in the present application.

[0151] In this embodiment, the annular sealing member 20 is arranged at the radially outer edge region of the end wall 10b. The annular sealing member 20 can surround a larger space so as to surround all the air inlets 100a and all the wire passing ports 10c.

[0152] In some embodiments, please refer to Figure 4 and Figure 5The wire passing hole 10c is arranged at the connection between the support arm 1023 and the outer ring structure 1022. In this way, the distance between the wire passing hole 10c and the circumferential side wall of the clothes treatment drum 10 and the distance between the wire passing hole 10c and the core 1021 are moderate. In the embodiment in which the receiving module 13 is arranged in the core 1021 and the electrical appliance element is arranged on the lifting rib 14, one end of the conductive wire harness 30 is electrically connected with the receiving module 13, the other end of the conductive wire harness 30 passes through the wire passing hole 10c and is electrically connected with the electrical appliance element, and the wire passing hole 10c is arranged at the connection between the support arm 1023 and the outer ring structure 1022, so that the winding can be reduced, the length of the conductive wire harness 30 can be relatively short, and the wiring is simple and compact.

[0153] In some embodiments, referring to Figure 7 The transmitting module 12 comprises a transmitting bracket 122, and the transmitting coil 121 is arranged on the transmitting bracket 122. The transmitting bracket 122 is connected with the cabinet 11. The transmitting coil 121 is fixed to the cabinet 11 through the transmitting bracket 122.

[0154] In some embodiments, referring to Figure 7 The transmitting bracket 122 comprises a ring body 1221 and a connecting lug 1222 connected with the ring body 1221. The transmitting coil 121 is arranged on the ring body 1221, and the connecting lug 1222 is connected with the cabinet 11, for example, the rear plate 111.

[0155] In this embodiment, the transmitting coil 121 and the ring body 1221 are both in a ring structure. The ring body 1221 provides a mounting space for the transmitting coil 121. The connecting lug 1222 is connected with the cabinet 11, for example, the rear plate 111. The transmitting coil 121 is stably mounted through the ring 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.

[0156] In some embodiments, the ring body 1221 is formed with a first ring groove, which is open toward one side of the clothes treatment drum 10. The transmitting coil 121 is accommodated in the first ring groove.

[0157] Specifically, the first ring groove is a ring space defined by the structure of the ring body 1221. The first ring groove is open toward one side of the clothes treatment drum 10, so as to facilitate the relative arrangement of the transmitting coil 121 and the receiving coil 131 and realize effective transmission of electric energy. The side of the first ring groove facing the rear plate 111 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 ring groove.

[0158] 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 ring groove matches the transmitting coil 121, so as to facilitate the transmitting coil 121 to be placed in the first ring groove.

[0159] The connecting lug 1222 can be detachably connected with the back plate 111, for example, the connecting lug 1222 can be connected with the back plate 111 by screws, which is not limited herein.

[0160] In some embodiments, referring to Figure 4 and Figure 5 The receiving module 13 comprises a receiving bracket 132, and the receiving coil 131 is arranged on the receiving bracket 132. The receiving bracket 132 is connected with the end wall 10b, for example, the back cover 102.

[0161] In some embodiments, referring to Figure 4 and Figure 5 The receiving module 13 comprises a receiving bracket 132 arranged on the end wall 10b. The receiving bracket 132 comprises an annular portion 1321 and a wire binding structure 1323. The receiving coil 131 is arranged on the annular portion 1321. The wire binding structure 1323 is connected to the outer peripheral side of the annular portion 1321. Part of the conductive wire bundle 30 is arranged on the wire binding structure 1323.

[0162] The wire binding structure 1323 is used for restraining the conductive wire bundle 30. The wire binding structure 1323 can provide support and restraint for the conductive wire bundle 30 located thereon, reduce assembly difficulty, and reduce the risk of displacement and misplacement of the conductive wire bundle 30.

[0163] Specifically, the receiving coil 131 and the annular portion 1321 are both annular structures. The shape of the receiving coil 131 can be substantially the same as the shape of the annular portion 1321.

[0164] The wire binding structure 1323 is connected to the outer peripheral side of the annular portion 1321, so as to facilitate the conductive wire bundle 30 to extend to the outer peripheral side of the receiving coil 131, thereby facilitating the conductive wire bundle 30 to be electrically connected with the electrical element.

[0165] Taking the end wall 10b with the back cover 102 as an example, referring to Figure 4 and Figure 5The annular portion 1321 can be arranged on the core portion 1021, and the bundle structure 1323 can be arranged on the support arm 1023. The support arm 1023 provides support for the bundle structure 1323, increases the installation stability, and also facilitates the bundle structure 1323 to avoid the air inlet 100a to avoid blocking the airflow.

[0166] In this embodiment, the bundle structure 1323 is used to constrain the conductive wire bundle 30, and in the case that the receiving module 13 rotates with the clothes treatment drum 10, the risk of displacement and misplacement of the conductive wire bundle 30 is reduced.

[0167] In some embodiments, referring to Figure 4 and Figure 5 , 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 used to install and fix the receiving support 132, for example, the connecting portion 1322 can be connected with the end wall 10b, for example, the rear cover 102.

[0168] In some embodiments, referring to Figure 4 and Figure 5 , the annular portion 1321 is formed with a second annular groove 1321a, which is open to one side of the rear plate 111, and the receiving coil 131 is accommodated in the second annular groove 1321a.

[0169] Specifically, the second annular groove 1321a is a ring-shaped space defined by the structure of the annular portion 1321, which is open to one side of the rear plate 111, facilitating the relative arrangement of the receiving coil 131 and the transmitting coil 121 to achieve effective power transmission. The side of the second annular groove 1321a facing the rear cover 102 can be in a closed state to provide support for the receiving coil 131 and reduce the probability of the receiving coil 131 detaching from the second annular groove 1321a.

[0170] The connecting portion 1322 can be detachably connected with the rear cover 102, for example, the connecting portion 1322 can be connected with the rear cover 102 by screws, which is not limited herein.

[0171] 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.

[0172] In some embodiments, the wire bundling structure 1323 forms a wire passing hole, a wire passing space is formed between the wire bundling structure 1323 and the end wall 10b, the receiving coil 131 is arranged on the side of the annular portion 1321 away from the end wall 10b, one end of the conductive wire bundle 30 is connected to the receiving coil 131, and the other end of the conductive wire bundle 30 passes through the wire passing hole and extends along the wire passing space.

[0173] Specifically, the wire bundling structure 1323 is spaced apart from the end wall 10b to form a wire passing space.

[0174] Taking the end wall 10b of the back cover 102 as an example, the annular portion 1321 can be arranged on the back side of the back cover 102, and the receiving coil 131 is arranged on the side of the annular portion 1321 away from the back cover 102, that is, the receiving coil 131 is arranged on the back side of the annular portion 1321.

[0175] In this embodiment, the other end of the conductive wire bundle 30 passes through the wire passing hole and extends along the wire passing space, that is, a part of the structure of the conductive wire bundle 30 is located between the wire bundling structure 1323 and the end wall 10b, and both the wire bundling structure 1323 and the end wall 10b can limit the conductive wire bundle 30, thereby playing a role of restricting the conductive wire bundle 30.

[0176] In some embodiments, the clothes treatment apparatus includes a back cover that covers the back side surface of the back plate 111 and cooperates with the back plate 111 to define an air supply passage, the back plate 111 forms an air supply port, and a sealing passage is connected between the air supply port and the air inlet 100a. The air flow of the air supply passage flows to the clothes treatment cavity 10a through the air supply port, the sealing passage, and the air inlet 100a.

[0177] For example, the clothes treatment drum 10 also has an air outlet, and the clothes treatment cavity 10a is connected between the air inlet 100a and the air outlet. Dry hot air flows into the clothes treatment cavity 10a from the air inlet 100a, and wet hot air flows out of the clothes treatment cavity 10a from the air outlet. The back plate 111 forms an air return port, the height of the air return port is lower than the height of the air supply port, the back cover covers the periphery of the air supply port and the air return port, and cooperates with the back plate 111 to define an air supply passage. The air supply passage is connected between the air return port and the air supply port, and the dry hot air flows into the clothes treatment cavity 10a through the air return port, the air supply passage, and the air supply port to dry the clothes.

[0178] For example, the clothes treatment apparatus can also include a base having a drying channel therein, the air supply passage and the drying channel together form a circulating air passage, the drying channel is located upstream of the air supply passage along the direction of air flow in the circulating air passage, and the air flow after 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, which enters the clothes treatment cavity 10a through the air return port, the air supply passage, and the air supply port.

[0179] 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.

[0180] In some embodiments, the clothes treatment device further comprises a heat exchange assembly located in the drying channel, the heat exchange assembly being configured to exchange heat with the airflow in the drying channel to dehumidify and heat. The wet and hot airflow in the clothes treatment drum 10 can enter the drying channel through the air outlet, exchange heat with the heat exchange assembly, and be converted into dry and hot airflow, which enters the air supply channel through the air return outlet, and then flows back to the clothes treatment cavity 10a through the air supply ports and the air inlet 100a.

[0181] In some embodiments, the heat exchange assembly comprises a condenser and an evaporator, and the clothes treatment device further comprises a compressor and a throttling device, the compressor, the condenser, the throttling device, and the evaporator being connected by pipelines to form a heat pump system, and a refrigerant can circulate in the heat pump system. The airflow in the circulating air duct exchanges heat with the refrigerant in the evaporator and the condenser to form dry and hot airflow. The evaporator is configured to cool and dehumidify the wet and hot airflow from the clothes treatment cavity 10a into dry and cold airflow, and the condenser is configured to heat the dry and cold airflow into dry and hot airflow to flow back to the clothes treatment cavity 10a.

[0182] 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. The high-pressure gaseous refrigerant enters the condenser, and the refrigerant in the condenser transfers heat to the airflow to condense into high-pressure liquid. The high-pressure liquid refrigerant is throttled and decompressed 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 the heat of the airflow to become low-pressure gaseous refrigerant, which is sucked in by the compressor again. This cycle is repeated to exchange heat. That is, the evaporator is configured to cool and dehumidify the wet and hot airflow from the clothes treatment cavity 10a into dry and cold airflow, and the condenser is configured to heat the dry and cold airflow into dry and hot airflow to flow back to the clothes treatment cavity 10a. The dry and hot airflow flowing back to the clothes treatment cavity 10a contacts the wet clothes to form wet and hot airflow again, completing a drying cycle. By repeatedly running the drying cycle, the circulating airflow is continuously provided to the clothes treatment cavity 10a to dry the clothes.

[0183] Exemplarily, the evaporator and the condenser can both be finned tube heat exchangers.

[0184] Exemplarily, the throttling device includes but is not limited to an electronic expansion valve, etc.

[0185] In some examples, the clothes treatment device further comprises an impeller, the impeller being configured to drive the airflow to flow. Exemplarily, the impeller is located in the drying channel and between the heat exchange assembly and the air return outlet. In the process of drying the clothes, the impeller is configured to drive the airflow flowing through the clothes to flow through the evaporator and the condenser in sequence, and then blow to the clothes to form circulating air. The impeller can accelerate the airflow to flow, and improve the drying efficiency.
