[0122] In some embodiments, the distance between the transmitting coil 121 and the receiving coil 131 is 4mm to 15mm. For example, 4mm, 4.5mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, etc.

[0123] It is to be noted that the distance between the transmitting coil 121 and the receiving coil 131 refers to the distance between the transmitting coil 121 and the receiving coil 131 in the axial direction when the transmitting coil 121 and the receiving coil 131 are oppositely arranged.

[0124] It can be understood that if the distance between the transmitting coil and the receiving coil is too large, the induced current generated by the receiving coil will be smaller, and thus the main control board needs to provide more working power for the transmitting coil. If the distance between the transmitting coil and the receiving coil is too small, the distance between the transmitting coil and the laundry treating drum will be smaller, which is easy to increase the interference probability between the transmitting coil and the laundry treating drum and increase the damage probability of the transmitting coil.

[0125] In this embodiment, the distance between the transmitting coil 121 and the receiving coil 131 is neither too large nor too small, and the transmitting coil 121 has a sufficient safety distance from the laundry treating drum 10. While increasing the working safety of the transmitting coil 121, the receiving coil 131 can generate an induced current of sufficient size to meet the power demand of the electrical components.

[0126] In some embodiments, the distance between the transmitting coil 121 and the receiving coil 131 is 5.5mm to 10mm. For example, 5.5mm, 5.7mm, 6mm, 6.2mm, 6.6mm, 7mm, 7.4mm, 8mm, 8.6mm, 9mm, 9.3mm, 9.8mm, 10mm, etc.

The dynamic sealing cooperation can realize sealing without affecting the rotation of the clothes treatment drum 10, thereby reducing the probability of air flow overflowing from the joint between the rear plate 111 and the clothes treatment drum 10.

[0130] It can be understood that the transmitting coil 121 is located within the rotational track range of the radial edge of the clothes treatment drum 10 refers to that, along the projection perpendicular to the front-rear direction of the clothes treatment apparatus 1, the projection of the transmitting coil 121 is located within the projection of the clothes treatment drum 10.

A part of the first cable 19 passes through the second wire passing port 111b of the rear plate 111 from the rear side of the rear plate 111 and is connected with the main control board in the cabinet 11.

[0132] That is, the main control board is located inside the cabinet 11. In the dynamic sealing cooperation state, the first cable 19 first passes through the first wire passing port 111a to the rear side of the rear plate 111, and then passes out from the second wire passing port 111b of the rear plate 111 to the cabinet 11 to realize electrical connection with the main control board, thereby realizing the electrically conductive path between the transmitting coil 121 and the main control board.

[0133] In this embodiment, the first wire port 111a and the second wire port 111b are arranged to realize the electrical connection between the transmitting coil 121 and the main control board.

[0202] In some embodiments, referring to FIGS. 9 and 10, the second annular portion 1321 includes a second annular plate 13211, a second inner annular wall 13212 disposed at a radially inner edge of the second annular plate 13211, and a second outer annular wall 13213 disposed at a radially outer edge of the second annular plate 13211, and a second annular groove 1321a is formed between the second inner annular wall 13212 and the second outer annular wall 13213.

[0203] Specifically, when the receiving coil 131 is matched with the second annular portion 1321, the receiving coil 131 is wrapped around the circumferential outer side of the second inner annular wall 13212 and located at the circumferential inner side of the second outer annular wall 13213, and one end of the receiving coil 131 in the axial direction is abutted against the second annular plate 13211, so as to realize the butt joint of the receiving coil 131 and the second annular portion 1321.

[0204] The second connecting portion 1322 is disposed at the radially outer side of the second outer annular wall 13213, or the second connecting portion 1322 is disposed at the radially inner side of the second inner annular wall 13212.

[0205] That is, one end of the second connecting portion 1322 can be connected with the second outer annular wall 13213, or connected with the second inner annular wall 13212, and the other end of the second connecting portion 1322 is connected with the rear cover 102, so as to realize the connection of the second support 132 and the rear cover 102. For example, referring to FIG. 9, the second connecting portion 1322 is disposed at the radially inner side of the second inner annular wall 13212. In this way, the probability that the second connecting portion 1322 affects the air inlet of the clothes treatment drum 10 at the rear cover 102 can be reduced.

[0206] In this embodiment, the butt joint of the receiving coil 131 and the second annular portion 1321 is convenient, the receiving coil 131 is convenient to disassemble and inspect, the structure of the second annular portion 1321 is simple, the manufacturing requirements of the second support 132 can be reduced, the setting position of the second connecting portion 1322 can also reduce the probability of interference with the receiving coil 131, and the relative arrangement of the receiving coil 131 and the transmitting coil 121 can be realized.

[0207] The second connecting portion 1322 can be detachably connected with the rear cover 102, for example, the second connecting portion 1322 can be connected with the rear cover 102 through a screw, which is not limited herein.

[0208] In some embodiments, referring to FIGS. 22 and 23, the clothes treatment apparatus 1 includes a second cable 30 and an electrical appliance element.

[0209] The laundry treatment drum 10 is provided with at least one lead port 10c. The number of lead ports 10c can be one or multiple, which is not limited herein. The lead port 10c can be arranged in the circumferential direction of the laundry treatment drum 10, or can be arranged at the rear end of the laundry treatment drum 10, which is not limited herein.

[0210] The electrical appliance element is arranged in the laundry treatment drum 10, that is, the electrical appliance element can be electrically connected with the receiving module 13, and the receiving module 13 supplies power to the electrical appliance element to meet the power demand.

[0211] At least a part of the receiving module 13 is arranged outside the laundry treatment drum 10. It can be understood that the outside of the laundry treatment drum 10 means that at least a part of the receiving module 13 is arranged on the outer surface of the laundry treatment drum 10, and the receiving module 13 can rotate with the rotation of the laundry treatment drum 10.

[0212] Specifically, the receiving module 13 can be arranged entirely outside the laundry treatment drum 10, or a part of the receiving module 13 can be arranged outside the laundry treatment drum 10, and the other part of the receiving module 13 can be arranged inside the laundry treatment drum 10.

[0213] The receiving module 13 and the electrical appliance element are electrically connected through the second cable 30, and the second cable 30 is arranged through the lead port 10c.

[0214] It can be understood that the electrical connection between the receiving module 13 and the electrical appliance element through the second cable 30 means that the second cable 30 can realize the electrical connection between the internal devices of the receiving module 13 and the electrical connection between the internal devices of the receiving module 13 and the electrical appliance element, thereby forming the electrical connection path between the whole receiving module 13 and the electrical appliance element.

[0215] Specifically, in the embodiment that the whole receiving module 13 is arranged outside the laundry treatment drum 10, the internal devices of the receiving module 13 can be integrated together, that is, the internal devices of the receiving module 13 have formed an electrical connection path, one end of the second cable 30 only needs to be connected with the internal devices, and the other end of the second cable 30 enters the laundry treatment drum 10 through the lead port 10c and is electrically connected with the electrical appliance element.

[0216] In the embodiment that a part of the receiving module 13 is arranged outside the laundry treatment drum 10, and the other part of the receiving module 13 is arranged inside the laundry treatment drum 10, one end of the second cable 30 is connected with the structure of the receiving module 13 arranged outside, and after being connected with the structure of the receiving module 13 arranged inside through the lead port 10c, the second cable 30 is further connected with the structure of the receiving module 13 arranged inside and the electrical appliance element to form an electrical connection path, so that the electrical appliance element can obtain the power supplied by the receiving module 13.

[0217] In this embodiment, at least part of the receiving module 13 is arranged outside the clothes treatment drum 10, which can reduce the probability of the receiving module 13 contacting the clothes, reduce the occupied space in the clothes treatment drum 10, and establish the electrical connection between the receiving module 13 and the electrical component arranged in the clothes treatment drum 10 through the second cable 30. When the clothes treatment drum 10 rotates, the receiving module 13 and the second cable 30 rotate synchronously, the electrical connection between the receiving module 13 and the electrical component is stable, so that the electrical component can perceive the state of the clothes in close proximity and perform specific functions, thereby improving the working performance of the clothes treatment equipment 1. In addition, the arrangement of the lead port 10c can also assist in positioning the second cable 30 and increase the stability of the second cable 30 rotating with the clothes treatment drum 10.

[0218] In some examples, the electrical component is arranged on the lifting rib 14.

[0219] It can be understood that, when the electrical component is arranged on the lifting rib 14, part of the structure of the electrical component can be arranged on the surface of the lifting rib 14, and the other part of the structure of the electrical component can be arranged in the lifting rib 14. For example, the wiring end of the electrical component is arranged in the lifting rib 14, and the detection end is arranged on the surface of the lifting rib 14. The wiring end is electrically connected to the receiving module 13 to obtain the electrical energy provided by the receiving module 13, and the detection end can be in close contact with the clothes, thereby realizing the close perception of the state of the clothes and the close performance of specific functions. The lifting rib 14 can reduce the probability of the wiring end contacting the clothes and increase the working reliability of the electrical component. In this way, the lifting rib 14 can drive the clothes to move while providing installation space for the electrical component and protecting the electrical component.

[0220] In some examples, the receiving coil 131 is arranged on the side of the rear cover 102 away from the drum body 101. Referring to FIGS. 22 and 23, at least one lead port 10c is arranged on the rear cover 102, and the second cable 30 is arranged in the lead port 10c. The second cable 30 can realize the electrical connection between the receiving coil 131 and the electrical component.

[0221] It should be noted that the electrical connection between the receiving coil 131 and the electrical component through the second cable 30 can be that the electrical connection between the receiving coil 131 and the electrical component does not have other intermediate elements, and the second cable 30 directly connects the receiving coil 131 and the electrical component; or the electrical connection between the receiving coil 131 and the electrical component has intermediate elements, for example, other components of the receiving module 13, and the second cable 30 sequentially connects the receiving coil 131, the intermediate elements, and the electrical component to form a conductive path; or the receiving coil 131 is integrated with other components of the receiving module 13, and the second cable 30 directly connects the other components of the receiving module 13 and the electrical component to realize the electrical connection between the receiving coil 131 and the electrical component.

[0222] In this embodiment, the second cable 30 is arranged in the lead port 10c on the rear cover 102 to establish an electrically conductive path between the receiving coil 131 and the electrical component, so as to meet the power requirement of the electrical component, perceive the state of the clothes and realize the specific function in a short distance. The length of the second cable 30 can be relatively short, and it is not necessary to wind the second cable 30. The electrically conductive connection between the receiving coil 131 and the electrical component is simple and convenient. In addition, the lead port 10c can also position the second cable 30, thereby increasing the stability of the second cable 30 rotating with the clothes treatment drum 10. The second cable 30 can be electrically connected with the electrical component in the lifting rib 14, thereby increasing the safety of the arrangement of the second cable 30 and improving the working reliability of the clothes treatment equipment 1.

[0223] In some embodiments, the receiving module 13 includes a receiving circuit board 133. Please refer to FIG. 13. The receiving circuit board 133 is arranged in the lifting rib 14. The second cable 30 includes a third sub-section and a fourth sub-section. The third sub-section is connected with the receiving circuit board 133 and the receiving coil 131. The fourth sub-section is connected with the receiving circuit board 133 and the electrical component.

[0224] In this embodiment, the receiving circuit board 133 and the receiving coil 131 are arranged separately. The receiving circuit board 133 serves as an intermediate element between the receiving coil 131 and the electrical component. The second cable 30 is divided into the third sub-section and the fourth sub-section. The third sub-section realizes the electrical connection between the receiving coil 131 and the receiving circuit board 133. The fourth sub-section realizes the electrical connection between the receiving circuit board 133 and the electrical component. For example, one end of the third sub-section is connected with the receiving coil 131. The other end of the third sub-section passes through the lead port 10c and enters the lifting rib 14 to be connected with the receiving circuit board 133. One end of the fourth sub-section is connected with the receiving circuit board 133. The other end of the fourth sub-section is connected with the wiring end of the electrical component.

[0225] Specifically, the receiving circuit board 133 can include a power output circuit. The receiving circuit board 133 can adjust and output the electric energy received by the receiving coil 131 and transmit the electric energy to the electrical component through the fourth sub-section, so that the electrical component can work.

[0226] At the same time, the distance between the receiving coil 131 and the receiving circuit board 133 can be relatively reasonable. For example, the length of the third sub-section is less than 50 mm (millimeter). For example, the length of the third sub-section is 50 mm, 45 mm, 40 mm, 36 mm, 30 mm, 28 mm, 24 mm, 20 mm, 15 mm, 12 mm, 10 mm, 5 mm, 2 mm, etc.

[0227] For example, please refer to FIG. 16. The lifting rib 14 can have a communication channel 14a extending along the length direction. The receiving circuit board 133 and the wiring end of the electrical component can be arranged in the communication channel 14a.

[0228] In some embodiments, the receiving circuit board 133 and the receiving coil 131 are integrated in the second support 132, and the second cable 30 connects the receiving circuit board 133 and the electrical component.

[0229] In this embodiment, the second support 132 integrates the receiving coil 131 and the receiving circuit board 133, i.e. the receiving coil 131 and the receiving circuit board 133 do not need to be connected by a wire, and the second cable 30 connects the receiving circuit board 133 and the electrical component, thereby realizing the electrical connection between the receiving coil 131 and the electrical component.

[0230] In this embodiment, the second cable 30 only needs to connect the receiving circuit board 133 and the electrical component to establish the conductive path between the receiving coil 131 and the electrical component, and the wiring is simple and convenient.

[0231] In some embodiments, referring to FIGS. 8 and 23, the lead-through port 10c penetrates the support arm 1023. That is, the second cable 30 can pass through the support arm 1023 into the clothes treatment cavity 10a.

[0232] In the embodiment in which the receiving circuit board 133 is arranged in the lifting rib 14, the second cable 30 includes a third sub-section and a fourth sub-section, the third sub-section passes through the lead-through port 10c on the support arm 1023 into the lifting rib 14 to be connected with the receiving circuit board 133, and the fourth sub-section connects the receiving circuit board 133 and the electrical component.

[0233] In the embodiment in which the receiving circuit board 133 and the receiving coil 131 are integrated in the second support 132, the receiving circuit board 133 and the receiving coil 131 are arranged on the side of the rear cover 102 away from the barrel 101, one end of the second cable 30 is connected with the receiving circuit board 133, and the other end passes through the lead-through port 10c on the support arm 1023 into the lifting rib 14 to be connected with the electrical component.

[0234] In this embodiment, the lead-through port 10c is arranged on the support arm 1023, a part of the second cable 30 is on the side of the rear cover 102 away from the barrel 101, and the other part passes through the lead-through port 10c into the lifting rib 14, i.e. the other part can pass into the lifting rib 14 away from the axis of the clothes treatment barrel 10, thereby reducing the winding of the second cable 30, shortening the length of the second cable 30, and increasing the wiring reliability.

[0235] In some embodiments, referring to FIG. 21, along the front-to-back direction of the clothes treatment apparatus 1, the lifting rib 14 blocks the lead-through port 10c, the end of the lifting rib 14 toward the support arm 1023 has an opening 142a, and one end of the second cable 30 passes through the lead-through port 10c and the opening 142a into the lifting rib 14.

[0236] That is, the lead-through port 10c is located within a projection of the lifting rib 14 in the front-rear direction, and the opening 142a is used for the second cable 30 to pass into the lifting rib 14.

[0237] In this embodiment, the lifting rib 14 shields the lead-through port 10c, which reduces the probability of the lead-through port 10c being exposed, so that the lifting rib 14 can shield the second cable 30 entering the clothes treatment cavity 10a, and reduces the probability of the second cable 30 contacting the clothes.

[0238] In some embodiments, referring to FIG. 21, the lifting rib 14 contacts the support arm 1023 at an end of the support arm 1023.

[0239] In this embodiment, the second cable 30 can pass through the lead-through port 10c to enter the lifting rib 14 through the opening 142a, which further reduces the probability of the second cable 30 being exposed in the clothes treatment cavity 10a, and increases the reliability of the electrical connection between the receiving coil 131 and the electrical component.

[0240] In some embodiments, referring to FIGS. 15 and 16, the lifting rib 14 includes a main body portion 141 and an extension portion 142, the main body portion 141 is arranged on the circumferential inner wall of the clothes treatment drum 10, the extension portion 142 protrudes from the main body portion 141 along the radially inner edge of the clothes treatment drum 10, and the opening 142a is arranged on the extension portion 142.

[0241] Specifically, the extension portion 142 and the space in the main body portion 141 together define the communication passage 14a. The extension portion 142 protrudes from the main body portion 141 along the radially inner edge of the clothes treatment drum 10, which can increase the volume of the communication passage 14a, so as to have sufficient space to accommodate the receiving circuit board 133, the electrical component, and the like.

[0242] The extension portion 142 shields the lead-through port 10c, so as to reduce the probability of the second cable 30 contacting the clothes.

[0243] Exemplarily, the extension portion 142 can extend towards the rotation axis of the clothes treatment drum 10, and in the radial direction of the clothes treatment drum 10, the vertex of the extension portion 142 protrudes from the vertex of the main body portion 141. That is, the outer profiles of both the main body portion 141 and the extension portion 142 are substantially L-shaped.

[0244] In other embodiments, referring to FIG. 22, the lead-through port 10c penetrates the core portion 1021.

[0245] That is, the second cable 30 can pass through the core portion 1021 to enter the clothes treatment cavity 10a.

[0246] In the embodiment where the receiving circuit board 133 is arranged in the lifting rib 14, the second cable 30 comprises a third sub-section and a fourth sub-section, the third sub-section passes through the lead-through opening 10c on the core portion 1021 into the clothes treatment cavity 10a and extends towards the direction away from the rotation axis of the clothes treatment drum 10 into the lifting rib 14 to be connected with the receiving circuit board 133, and the fourth sub-section is connected with the receiving circuit board 133 and the electrical component.

[0247] In the embodiment where the receiving circuit board 133 and the receiving coil 131 are integrated in the second support 132, the receiving circuit board 133 and the receiving coil 131 are arranged on the side of the rear cover 102 away from the drum body 101, one end of the second cable 30 is connected with the receiving circuit board 133, and the other end passes through the lead-through opening 10c on the core portion 1021 into the clothes treatment cavity 10a and extends towards the direction away from the rotation axis of the clothes treatment drum 10 into the lifting rib 14 to be connected with the electrical component.

[0248] In this embodiment, the lead-through opening 10c is arranged on the core portion 1021, which can reduce the probability of the second cable 30 being wound on the side of the rear cover 102 away from the drum body 101, and the second cable 30 is arranged in the core portion 1021, which can also increase the stability of the second cable 30 when the clothes treatment drum 10 rotates, thereby increasing the reliability of the connection.

[0249] In still other embodiments, the lead-through opening 10c is located in the interval region between the two adjacent support arms 1023.

[0250] In this embodiment, the interval region between the two support arms 1023 can be fully utilized for the second cable 30 to pass through, and the lead-through opening 10c has sufficient arrangement space for the second cable 30 to pass through.

[0251] In some embodiments, the clothes treatment apparatus 1 comprises a ring-shaped sealing member 20. The clothes treatment drum 10 is rotatably arranged in the cabinet 11, and the clothes treatment drum 10 comprises an end wall 10b and a clothes treatment cavity 10a. The end wall 10b forms a lead-through opening 10c, and the lead-through opening 10c is in communication with the clothes treatment cavity 10a. The ring-shaped sealing member 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 lead-through opening 10c is located on the side of the ring-shaped sealing member 20 close to the rotation axis P of the clothes treatment drum 10. The second cable 30 passes through the lead-through opening 10c and extends into the clothes treatment cavity 10a.

[0252] In some embodiments, referring to FIGS. 8 and 23, the end wall 10b forms an air inlet 100a in communication with the clothes treatment cavity 10a, and the air inlet 100a is used to send air flow into the clothes treatment cavity 10a. The air inlet 100a can be located on the side of the ring-shaped sealing member 20 close to the rotation axis P of the clothes treatment drum 10. The lead-through opening 10c and the air inlet 100a can both penetrate the end wall 10b.

[0253] 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, the annular seal 20 can realize sealing between the end wall 10b and the cabinet 11 during rotation of the clothes treatment drum 10 relative to 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 rear 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 for the airflow to enter the air inlet 100a. In this way, the airflow can be prevented from leaking to the outside of the clothes treatment cavity 10a to some extent, and the drying efficiency is improved.

[0254] The projection of the annular seal 20 is annular in a plane perpendicular to the axial direction of the clothes treatment drum 10. The lead-through 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 lead-through opening 10c and the air inlet 100a are located on the side of the annular seal 20 radially close to the rotation axis, and the annular seal 20 can surround the air inlet 100a and the lead-through opening 10c.

[0255] It can be understood that in the embodiments of the present application, the axial direction refers to the extension direction of the rotation axis P of the clothes treatment drum 10, and the radial direction is perpendicular to the axial direction.

[0256] The second cable 30 passes through the lead-through opening 10c and extends into the clothes treatment cavity 10a. In this way, electrical components can be arranged inside the clothes treatment cavity 10a, and the second cable 30 can be routed outside and inside the clothes treatment cavity 10a according to the position requirements of the electrical components.

[0257] If the lead-through opening 10c is located on the side of the annular seal 20 radially away from the rotation axis, the second cable 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, and the second cable 30 is rubbed during rotation of the annular seal 20, which is prone to damage.

[0258] In the present application, since the lead-through opening 10c is located on the side of the annular seal 20 radially close to the rotation axis, the second cable 30 can not pass through the annular seal 20, which can avoid the risk of abrasion of the wire harness to some extent, and also can not damage the annular seal 20, thereby ensuring the drying effect.

[0259] In this embodiment, the second cable 30 is arranged in the lead-through opening 10c and extends into the clothes treatment cavity 10a. The electrical component can be arranged inside the clothes treatment cavity 10a. According to the position requirement of the electrical component, the second cable 30 can be arranged outside the clothes treatment cavity 10a and inside the clothes treatment cavity 10a, which reduces the wiring difficulty of the second cable 30. The lead-through opening 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 second cable 30 can not pass through the annular sealing member 20, which can avoid the risk of abrasion of the second cable 30 to a certain extent, and can also not damage the annular sealing member 20, thereby ensuring the drying effect.

[0260] 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.

[0261] For example, the rotation axis P of the clothes treatment drum 10 can be in a horizontal direction, which can also be referred to as a drum-type clothes dryer.

[0262] For example, the rear cover 102 has an end wall 10b, and the annular sealing member 20 is arranged between the rear cover 102 and the rear plate 111.

[0263] The rear cover 102 has an end wall 10b, that is, the air inlet 100a and the lead-through opening 10c are formed in the rear cover 102. The dry hot air flow enters the clothes treatment cavity 10a from the rear side through the air inlet 100a.

[0264] The annular sealing member 20 can be arranged on the rear side of the rear cover 102. The rear cover 102 and the rear plate 111 realize dynamic sealing through the annular sealing member 20.

[0265] In this embodiment, the second cable 30 passes through the lead-through opening 10c from the rear side into the clothes treatment cavity 10a. The user can take and place clothes from the front side as much as possible to reduce the interference of the second cable 30 with the taking and placing of clothes. The part of the second cable 30 outside the clothes treatment cavity 10a can be electrically connected with the receiving module 13. The receiving module 13 and the lead-through opening 10c are located on the same side of the annular sealing member 20 in the radial direction. The second cable 30 does not need to pass through the annular sealing member 20.

[0266] In some embodiments, referring to FIGS. 8 to 23, the receiving module 13 includes a second bracket 132 arranged on the end wall 10b. The second bracket 132 includes a second annular portion 1321 and a wire binding structure 1323. The receiving coil 131 is arranged on the second annular portion 1321. The wire binding structure 1323 is connected to the outer circumferential side of the second annular portion 1321. Part of the second cable 30 is arranged in the wire binding structure 1323.

[0267] The wire binding structure 1323 is used to constrain the second cable 30, and can provide support and constraint for the second cable 30 located thereon, reduce assembly difficulty, and reduce the risk of displacement and misplacement of the second cable 30.

[0268] Specifically, the receiving coil 131 and the second annular portion 1321 are both annular structures, and the shape of the receiving coil 131 can be substantially the same as the shape of the second annular portion 1321.

[0269] The wire binding structure 1323 is connected to the outer circumferential side of the second annular portion 1321, so as to facilitate the second cable 30 extending to the outer circumferential side of the receiving coil 131, thereby facilitating the electrical connection between the second cable 30 and the electrical component.

[0270] Taking the end wall 10b of the back cover 102 as an example, referring to FIGS. 2 to 4, the second annular portion 1321 can be arranged on the core portion 1021, and the wire binding structure 1323 can be arranged on the support arm 1023. The support arm 1023 provides support for the wire binding structure 1323, increases installation stability, and also facilitates the wire binding structure 1323 to avoid the air inlet 100a, so as to avoid blocking the airflow.

[0271] In this embodiment, the wire binding structure 1323 is used to constrain the second cable 30, and in the case that the receiving module 13 rotates with the laundry treatment drum 10, the risk of displacement and misplacement of the second cable 30 is reduced.

[0272] It can be understood that the outer contour shape of the second 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 second 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 second 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 second annular portion 1321 can also be the same polygonal.

The second teeth 1514 are in contact with the clothes away from the surface of the lifting rib 14, and the curved surface can avoid hooking the clothes to some extent, reducing the mutual abrasion between the clothes and the second teeth 1514.

Both the first terminal 1515 and the second terminal 1516 extend into the lifting rib 14 and are electrically connected with the detection circuit.

[0322] For example, the first terminal 1515 is connected with one of the first teeth 1512, and the second terminal 1516 is connected with one of the second teeth 1514.

[0323] In this embodiment, the first terminal 1515 and the second terminal 1516 are connected with the detection circuit to transmit electrical signals between the detection circuit and the detection electrode 151.

[0326] In some examples, the second electrode piece can be a one-piece structure. That is, the second connecting structure 1513 and the second teeth 1514, etc. can be manufactured in one piece.

[0327] In some examples, the second electrode piece and the second terminal 1516 can be a one-piece structure.

[0328] The specific configuration of the lifting rib 14 is not limited, and in some examples, referring to FIGS. 15 and 16, the lifting rib 14 includes a main body portion 141 and an extension portion 142, the main body portion 141 is arranged on the circumferential surface of the clothes treatment cavity 10a, the extension portion 142 is connected to the rear end of the main body portion 141 and arranged on the rear surface of the clothes treatment cavity 10a, and the space in the main body portion 141 and the space in the extension portion 142 define a communication passage 14a. Arranging the extension portion 142 on the rear surface of the clothes treatment cavity 10a can increase the volume of the communication passage 14a without increasing the radial dimension of the lifting rib 14, thereby accommodating the receiving circuit board 133, the detection circuit of the detection unit 15, etc.; the extension portion 142 can cover part of the area of the rear surface of the clothes treatment cavity 10a to shield the hole for passing the wire arranged on the rear sidewall of the clothes treatment drum 10.

[0329] In some examples, referring to FIG. 16, the extension portion 142 has an opening 142a facing the rear side, and the rear surface of the clothes treatment cavity 10a can shield the opening 142a of the extension portion 142 facing the rear side.

[0331] In some examples, the rear surface of the extension portion 142 is flush with the rear surface of the clothes treatment cavity 10a.

[0332] In some examples, the clothes treatment device 1 further includes a heat exchange assembly arranged in the drying channel, the heat exchange assembly is configured to exchange heat with the airflow in the drying channel, thereby dehumidifying and heating.

[0333] In some examples, 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 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 hot airflow. The evaporator is configured to cool and dehumidify the humid hot airflow from the clothes treatment cavity 10a to form dry cold airflow; the condenser heats the dry cold airflow to form dry hot airflow to flow back to the clothes treatment cavity 10a.

[0334] 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 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 gaseous refrigerant, which is sucked into the compressor again. Such a cycle is repeated to exchange heat. That is, the evaporator is used to cool and dehumidify the wet and hot air flow from the clothes treatment cavity 10a to form a dry and cold air flow, and the condenser heats the dry and cold air flow to become a dry and hot air flow and returns to the clothes treatment cavity 10a. The dry and hot air flow returned to the clothes treatment cavity 10a contacts the wet clothes to form a wet and hot air flow again, completing a drying cycle. By repeatedly operating the drying cycle, the circulating air flow is continuously provided to the clothes treatment cavity 10a to dry the clothes.

[0335] Exemplarily, the evaporator and the condenser can both be finned tube heat exchangers.

[0336] Exemplarily, the throttling device includes, but is not limited to, an electronic expansion valve, etc.

[0337] In some examples, the clothes treatment apparatus 1 further includes an impeller for driving the air flow. Exemplarily, the impeller is located in the drying channel and between the heat exchange assembly and the return air inlet. In the process of drying the clothes, the impeller is used to drive the air flow flowing through the clothes to flow through the evaporator and the condenser in turn, and then blow to the clothes to form a circulating air flow. The impeller can accelerate the air flow and improve the drying efficiency.
