[0057] The present application embodiment provides a clothes processing device 1, see Figures 1 to 20 The clothing processing device 1 includes a clothing processing drum 10 , a wireless power supply component, electrical components and cables 19 .

[0058] It is understandable that the type of the clothes processing device 1 is not limited, and it can be a clothes dryer, a washer-dryer, etc., which is not limited here. For example, the clothes processing device 1 of the present application is described as a clothes dryer.

[0059] The laundry treatment drum 10 has a laundry treatment chamber 10a. The laundry treatment drum 10 can be used to place and dry laundry, and the laundry treatment drum 10 can drive the laundry to rotate. Taking a drum dryer as an example, the rotation axis of the laundry treatment drum 10 is in the horizontal direction, and the front side of the laundry treatment drum 10 has a laundry delivery port, through which the user puts or takes out the laundry treatment chamber 10a. During the rotation process, the laundry treatment drum 10 drives the laundry to move from the bottom to the top, and the laundry falls from the top to the bottom under the action of gravity. In this way, the laundry is dispersed, thrown and changes its posture under the combined action of the laundry treatment drum 10 and gravity.

[0060] It is understandable that the laundry treatment drum 10 may be a single drum structure, that is, the laundry treatment device 1 may have only one drum body, namely, the laundry treatment drum 10. Of course, in other examples, the laundry treatment device 1 may also include an outer drum, which is arranged outside the circumference of the laundry treatment drum 10.

[0061] The embodiment of the present application is described by taking the clothing processing device 1 adopting a single-drum structure as an example.

[0062] Exemplarily, the laundry treatment drum 10 is substantially in the shape of a hollow cylinder. The laundry treatment drum 10 can be made of metal material, such as stainless steel, etc., which is not limited here.

[0063] The laundry treatment drum 10 is provided with at least one lead-in port 102a. The number of the lead-in ports 102a can be one or more, which is not limited here. The lead-in port 102a can be provided in the circumference of the laundry treatment drum 10 or at the rear end of the laundry treatment drum 10, which is not limited here.

[0064] The wireless power supply component is a structure that provides electrical energy to the electrical components in the clothing processing device 1 in a wireless manner.

[0065] The wireless power supply component includes a transmitting module 12 and a receiving module 13. The receiving module 13 is used to receive the electromagnetic signal transmitted by the transmitting module 12 and generate an induced current.

[0066] The transmitting module 12 and the receiving module 13 can be wirelessly connected by electromagnetic induction.

[0067] Exemplarily, the transmitting module 12 can be electrically connected to the main control board of the clothes processing device 1, and the main control board can control the operation of the clothes processing device 1 and provide power to the transmitting module 12 so that each part can work normally to realize functions such as clothes drying control. Exemplarily, the transmitting module 12 can be electrically connected to the main control board through a connecting line to receive the power supplied by the main control board, so as to transmit an electromagnetic signal to the receiving module 13.

[0068] The electrical components are arranged in the clothes processing drum 10, that is, the electrical components can be electrically connected to the receiving module 13, and the receiving module 13 is used to supply power to the electrical components to meet the power demand.

[0069] It should be noted that an electrical component may be a structural component that can realize an electrical function and / or is used in a circuit to realize at least one electrical function. The number of electrical components may be one, two, three or more.

[0070] The electrical components may include units for detecting the status of laundry and other units having specific functions to improve the performance of drying laundry.

[0071] At least a portion of the receiving module 13 is disposed outside the laundry treatment drum 10. It is understood that the outside of the laundry treatment drum 10 means that at least a portion of the receiving module 13 is disposed 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.

[0072] Specifically, the receiving module 13 may be entirely disposed outside the laundry processing drum 10 , or may be partially disposed outside the laundry processing drum 10 and have another partially disposed inside the laundry processing drum 10 .

[0073] The location of the transmitter module 12 is not limited, as long as it can realize wireless power transmission with the receiving module 13. For example, the transmitter module 12 can be arranged on the box 11, on the base 16 below the laundry treatment drum 10, etc., which is not limited here.

[0074] The receiving module 13 and the electrical components are conductively connected via a cable 19 , and the cable 19 is passed through the lead-in port 102 a .

[0075] It can be understood that the conductive connection between the receiving module 13 and the electrical components is established through the cable 19, which means that the cable 19 can realize the electrical connection between the internal components of the receiving module 13 and the electrical connection between the internal components of the receiving module 13 and the electrical components, thereby forming a conductive path between the entire receiving module 13 and the electrical components.

[0076] Specifically, in an embodiment where the entire structure of the receiving module 13 is arranged outside the clothing processing drum 10, the internal components of the receiving module 13 can be integrated together, that is, the internal components of the receiving module 13 have formed a conductive path, and one end of the cable 19 only needs to be connected to the internal components, and the other end passes through the lead-in port 102a to enter the clothing processing drum 10 and be electrically connected to the electrical components.

[0077] In an embodiment in which part of the structure of the receiving module 13 is arranged outside the clothing processing drum 10 and the other part of the structure is arranged inside the clothing processing drum 10, one end of the cable 19 is connected to the structure arranged outside the receiving module 13, passes through the lead-in port 102a to be connected to the structure arranged inside the receiving module 13, and then connects the structure arranged inside the receiving module 13 and the electrical components to form a conductive path, so that the electrical components can obtain the electrical energy supplied by the receiving module 13.

[0078] In the related art, taking the clothing processing equipment as a dryer as an example, because the clothing processing drum is in a rotating state, considering the problems of power supply and signal transmission, electrical components such as units for detecting the status of clothing and units with specific functions cannot be placed directly in the clothing processing drum. If it is necessary to determine whether the clothing is completely dried, the unit for detecting the status of clothing can only be placed at the air inlet and outlet of the clothing processing drum, and whether the clothing is dry is determined by the difference in air flow states at the inlet and outlet. This method has low detection accuracy, and the electrical components cannot sense the status of clothing and perform specific functions at close range.

[0079] In the clothing processing device 1 provided in the embodiment of the present application, the transmitting module 12 and the receiving module 13 can transmit electric energy without contact, and do not need to be connected by wires, so the reliability is high. At least a part of the receiving module 13 is arranged outside the clothing processing drum 10, which can reduce the probability of the receiving module 13 contacting the clothing and reduce the space occupied in the clothing processing drum 10. In addition, an electrical connection is established between the receiving module 13 and the electrical components arranged in the clothing processing drum 10 through the cable 19. When the clothing processing drum 10 rotates, the receiving module 13 and the cable 19 rotate synchronously, and the electrical connection between the receiving module 13 and the electrical components is stable, so that the electrical components can sense the clothing status and perform specific functions at close range, so as to improve the working performance of the clothing processing device 1. In addition, the setting of the lead-in port 102a can also assist in positioning the cable 19 and increase the stability of the cable 19 rotating with the clothing processing drum 10.

[0080] For some examples, see Figure 1 and Figure 2 The laundry processing apparatus 1 comprises lifting ribs 14 which protrude radially from the circumferential inner wall of the laundry processing tub 10 .

[0081] See also Figure 1 and Figure 2 The laundry processing drum 10 includes a drum body 101 and a rear cover 102 , and the rear cover 102 is located at the rear end of the drum body 101 .

[0082] Specifically, the front side of the barrel 101 is open to form a clothing inlet, and the rear end cooperates with the rear cover 102, and the barrel 101 and the rear cover 102 together define the clothing processing chamber 10a. Exemplarily, the rear end of the barrel 101 can be detachably connected to the rear cover 102.

[0083] Exemplarily, the lifting ribs 14 protrude from the circumferential inner wall of the barrel 101 along the radial direction of the barrel 101 .

[0084] Specifically, the lifting ribs 14 can contact the clothes in the clothes processing chamber 10a and drive the clothes to rotate with the clothes processing drum 10. For example, the clothes move from bottom to top under the action of the lifting ribs 14, and then move downward under the action of gravity and centrifugal force, so that the clothes constantly change their posture in the clothes processing chamber 10a.

[0085] The electrical components are arranged on the lifting ribs 14 .

[0086] It is understandable that the electrical component is disposed on the lifting rib 14, and part of the structure of the electrical component can be disposed on the surface of the lifting rib 14, and another part of the structure is disposed inside the lifting rib 14. For example, the wiring terminal of the electrical component is disposed inside the lifting rib 14, and the detection terminal is disposed on the surface of the lifting rib 14. The wiring terminal is electrically connected to the receiving module 13 to obtain the electric energy provided by the receiving module 13. The detection terminal can be in close contact with the clothing, thereby realizing close-range perception of the clothing state and close-range realization of specific functions. The lifting rib 14 can reduce the probability of the wiring terminal contacting the clothing and increase the working reliability of the electrical component. In this way, while driving the clothing to move, the lifting rib 14 can also provide installation space for the electrical component and protect the electrical component.

[0087] The receiving module 13 includes a receiving coil 131 .

[0088] Exemplarily, the transmitting module 12 includes a transmitting coil 121, and the receiving coil 131 is used to receive the electromagnetic signal transmitted by the transmitting coil 121 and generate an induced current. That is, the transmitting coil 121 generates a changing magnetic field, and the receiving coil 131 generates an induced current through electromagnetic induction and receives the power transmission from the transmitting coil 121. In this way, the power transmission between the transmitting module 12 and the receiving module 13 is realized. Figure 1 and Figure 3 The receiving coil 131 is arranged on a side of the rear cover 102 away from the barrel body 101 .

[0089] In this way, the receiving coil 131 does not contact the clothes in the clothes processing chamber 10a, reducing the influence of water vapor or hair on the clothes on the receiving coil 131, and increasing the working safety of the receiving coil 131. In addition, the receiving coil 131 is arranged on the side of the rear cover 102 away from the drum body 101, which can also facilitate the relative arrangement of the receiving coil 131 and the transmitting coil 121 located outside the clothes processing drum 10.

[0090] At least one lead-in opening 102a is provided on the rear cover 102, and the cable 19 is passed through the lead-in opening 102a. The cable 19 can realize the electrical connection between the receiving coil 131 and the electrical components.

[0091] It should be noted that the cable 19 can realize the electrical connection between the receiving coil 131 and the electrical component. It can be that there is no other intermediate component in the electrical connection between the receiving coil 131 and the electrical component, and the cable 19 directly connects the receiving coil 131 and the electrical component; it can also be that there is an intermediate component in the electrical connection between the receiving coil 131 and the electrical component, for example, other components of the receiving module 13, and the cable 19 connects the receiving coil 131, the intermediate component, and the electrical component in sequence to form a conductive path; it can also be that the receiving coil 131 is integrated with other components of the receiving module 13, and the cable 19 directly connects 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.

[0092] In the embodiment of the present application, the lifting rib 14 provides installation space for the electrical components, and the cable 19 is passed through the lead-in port 102a on the rear cover 102 to establish a conductive path between the receiving coil 131 and the electrical components to meet the power demand of the electrical components and to sense the state of clothing at close range and to achieve specific functions. The length of the cable 19 can be short and no winding is required. The conductive connection between the receiving coil 131 and the electrical components is simple and convenient. In addition, the lead-in port 102a can also position the cable 19 to increase the stability of the cable 19 rotating with the clothing treatment drum 10. The cable 19 can be electrically connected to the electrical components in the lifting rib 14, which increases the safety of the cable 19 and improves the working reliability of the clothing treatment device 1.

[0093] In some embodiments, the receiving module 13 includes a receiving circuit board 133, see Fig.19 The receiving circuit board 133 is arranged in the lifting rib 14, and the cable 19 includes a first sub-segment and a second sub-segment. The first sub-segment connects the receiving circuit board 133 and the receiving coil 131, and the second sub-segment connects the receiving circuit board 133 and the electrical component.

[0094] In this embodiment, the receiving circuit board 133 and the receiving coil 131 are dispersedly arranged, and the receiving circuit board 133 serves as an intermediate element between the receiving coil 131 and the electrical component. The cable 19 is divided into a first sub-segment and a second sub-segment. The first sub-segment realizes the electrical connection between the receiving coil 131 and the receiving circuit board 133, and the second sub-segment realizes the electrical connection between the receiving circuit board 133 and the electrical component. Exemplarily, one end of the first sub-segment is connected to the receiving coil 131, and the other end passes through the lead-in opening 102a and enters the lifting rib 14 to be connected to the receiving circuit board 133, and one end of the second sub-segment is connected to the receiving circuit board 133, and the other end is connected to the wiring terminal of the electrical component.

[0095] Specifically, the receiving circuit board 133 may include a power output circuit, and the receiving circuit board 133 can adjust and output the electric energy received by the receiving coil 131, and transmit it to the electrical component through the second sub-segment, so that the electrical component can work.

[0096] In some examples, the receiving circuit board 133 may also include a modulation and demodulation circuit, which can realize signal conversion. That is, while supplying power to the electrical components, the receiving module 13 can also receive and transmit information detected by the electrical components.

[0097] Of course, in some other examples, the clothing processing device 1 may also be provided with a wireless transmission unit, the receiving module 13 can provide power to the wireless transmission unit through the receiving circuit board 133, and the wireless transmission unit can receive clothing information detected by the electrical components and transmit it wirelessly.

[0098] In this embodiment, the receiving coil 131 is arranged on the side of the rear cover 102 away from the barrel 101, the receiving circuit board 133 is arranged in the lifting rib 14, and the cable 19 establishes a conductive path between the receiving coil 131, the receiving circuit board 133 and the electrical components. On the one hand, the receiving coil 131 can be arranged as close to the transmitting coil 121 as possible, and the receiving circuit board 133 can be arranged as close to the electrical components as possible. The receiving coil 131 obtains sufficient electrical energy, and the receiving circuit board 133 supplies sufficient electrical energy to the electrical components, thereby reducing the loss of electrical energy supply. In addition, the receiving coil 131 and the receiving circuit board 133 can be arranged in smaller areas respectively, thereby reducing the impact on the overall layout of the clothing processing device 1, and the lifting rib 14 is used to provide an installation space for the receiving circuit board 133, thereby increasing the installation safety of the receiving circuit board 133.

[0099] Meanwhile, the distance between the receiving coil 131 and the receiving circuit board 133 can be reasonable. Exemplarily, the length of the first sub-segment is less than 50 mm (millimeter), for example, 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.

[0100] For example, see Fig.13 The lifting rib 14 may have a connecting passage 14a extending in the length direction, and the connection terminals of the receiving circuit board 133 and the electrical components may be arranged in the connecting passage 14a.

[0101] For some examples, see Figure 3 and Figure 6 , the receiving module 13 includes a bracket 132 .

[0102] The receiving circuit board 133 and the receiving coil 131 are electrically connected, and the receiving circuit board 133 and the receiving coil 131 are integrated into the bracket 132 , and the cable 19 connects the receiving circuit board 133 and the electrical components.

[0103] In this embodiment, the bracket 132 integrates the receiving coil 131 and the receiving circuit board 133, that is, the receiving coil 131 and the receiving circuit board 133 do not need to be connected by wires, and the cable 19 connects the receiving circuit board 133 and the electrical component, thereby realizing the electrical connection between the receiving coil 131 and the electrical component.

[0104] In this embodiment, the receiving coil 131 and the receiving circuit board 133 are integrated by the bracket 132, which reduces the high assembly complexity caused by the interlacing of wires, makes power transmission more convenient, reduces power loss and electromagnetic interference, and the receiving coil 131 and the receiving circuit board 133 are arranged on the same plane. The overall structure of the receiving module 13 is simple and compact, and the installation and maintenance of each component are convenient. The bracket 132 can provide installation support for the receiving coil 131 and the receiving circuit board 133, and increase the installation stability of the receiving coil 131 and the receiving circuit board 133. In addition, the cable 19 only needs to connect the receiving circuit board 133 and the electrical component to establish a conductive path between the receiving coil 131 and the electrical component, and the wiring is simple and convenient.

[0105] Of course, in the embodiment where the receiving coil 131 and the receiving circuit board 133 are spaced apart, the receiving coil 131 may also be supported on the bracket 132 , and connected to the back cover 102 via the bracket 132 .

[0106] For some examples, see Figure 3 and Figure 4 The back cover 102 includes a core 1021, an outer ring structure 1022 and a plurality of support arms 1023. The outer ring structure 1022 surrounds the circumferential outer side of the core 1021. The plurality of support arms 1023 are radially arranged along the circumference of the core 1021. The support arms 1023 connect the outer ring structure 1022 and the core 1021. The lead-in port 102a passes through the support arms 1023.

[0107] It is understandable that the core 1021 is roughly arranged in the central area of ​​the rear cover 102, and the plurality of support arms 1023 are radially distributed along the circumference of the core 1021, which means that the plurality of support arms 1023 are arranged around the axis of the core 1021, and the support arms 1023 can extend along a straight line or in a curve, which is not limited here. Exemplarily, the receiving coil 131 is arranged on the side of the core 1021 away from the barrel 101. In other words, the receiving coil 131 can be roughly arranged in the central area of ​​the rear cover 102, so as to facilitate the coaxial arrangement of the receiving coil 131 and the laundry treatment barrel 10.

[0108] The support arm 1023 connects the core 1021 and the outer ring structure 1022 together, so that the rear cover 102 has sufficient structural strength and the structural stability of the clothing processing drum 10 is increased.

[0109] Exemplarily, the support arm 1023 may be integrally formed with the core 1021 and the outer ring structure 1022; or, the support arm 1023 may be connected with the core 1021 and the outer ring structure 1022 by rivets, welding, threaded connection, etc., which are not limited here.

[0110] See also Figure 3 The lead-in port 102a passes through the support arm 1023 , that is, the cable 19 can pass through the support arm 1023 and enter the clothing processing chamber 10a .

[0111] In an embodiment in which the receiving circuit board 133 is disposed in the lifting rib 14, the cable 19 includes a first sub-segment and a second sub-segment. The first sub-segment passes through the lead-in opening 102a on the support arm 1023 and enters the lifting rib 14 to be connected to the receiving circuit board 133, and the second sub-segment connects the receiving circuit board 133 and the electrical component.

[0112] In the embodiment where the receiving circuit board 133 and the receiving coil 131 are integrated in the bracket 132, the receiving circuit board 133 and the receiving coil 131 are arranged on the side of the back cover 102 away from the barrel body 101, one end of the cable 19 is connected to the receiving circuit board 133, and the other end passes through the lead-in port 102a on the support arm 1023 and enters the lifting rib 14 to be connected to the electrical components.

[0113] In this embodiment, the lead-in opening 102a is arranged on the support arm 1023, a part of the cable 19 is on the side of the rear cover 102 away from the barrel body 101, and the other part passes through the lead-in opening 102a and enters the lifting rib 14, that is, the other part can be passed through the lifting rib 14 away from the axis of the clothing processing barrel 10, thereby reducing the winding of the cable 19, shortening the length of the cable 19, and increasing the wiring reliability.

[0114] For some examples, see Figure 5 and Fig.13 , along the direction from front to back of the clothing processing device 1, the lifting rib 14 blocks the lead-in port 102a, and the end of the lifting rib 14 facing the support arm 1023 has an opening 142a, and one end of the cable 19 enters the lifting rib 14 through the lead-in port 102a and the opening 142a.

[0115] That is to say, the lead-in opening 102 a is located within the projection of the lifting rib 14 along the front-to-back direction, and the opening 142 a is used for allowing the cable 19 to pass through the lifting rib 14 .

[0116] In this embodiment, the lifting ribs 14 shield the lead-in opening 102a, which can reduce the probability of the lead-in opening 102a being exposed, so that the lifting ribs 14 can shield the cable 19 entering the clothing processing chamber 10a, reducing the probability of the cable 19 contacting the clothing.

[0117] For some examples, see Figure 5 , the end of the lifting rib 14 facing the support arm 1023 contacts the support arm 1023 .

[0118] In this embodiment, the cable 19 can pass through the lead-in port 102a and enter the lifting rib 14 through the opening 142a, further reducing the probability of the cable 19 being exposed in the clothing processing chamber 10a and increasing the reliability of the electrical connection between the receiving coil 131 and the electrical components.

[0119] For some examples, see Fig.12 and Fig.13 The lifting rib 14 includes a main body 141 and an extension 142 . The main body 141 is arranged on the circumferential inner wall of the clothing processing tub 10 . The extension 142 protrudes from the radial inner edge of the main body 141 along the clothing processing tub 10 . The opening 142 a is arranged on the extension 142 .

[0120] Specifically, the extension 142 and the space in the main body 141 together define a communication channel 14a. The extension 142 protrudes from the radial inner edge of the main body 141 along the laundry treatment tub 10, and can increase the volume of the communication channel 14a to have enough space to accommodate the receiving circuit board 133, electrical components, etc.

[0121] The extension portion 142 shields the lead-in port 102 a to reduce the probability of the cable 19 contacting clothing.

[0122] Exemplarily, the extension portion 142 may extend toward the rotation axis of the laundry treatment tub 10, and the apex of the extension portion 142 protrudes from the apex of the main body 141 in the radial direction of the laundry treatment tub 10. That is, the main body 141 and the extension portion 142 are both substantially L-shaped.

[0123] In some other embodiments, please refer to Figure 6 The lead wire opening 102 a penetrates the core portion 1021 .

[0124] That is, the cable 19 can pass through the core 1021 and enter the laundry treatment chamber 10a.

[0125] In an embodiment in which the receiving circuit board 133 is arranged in the lifting rib 14, the cable 19 includes a first sub-segment and a second sub-segment. The first sub-segment passes through the lead-in opening 102a on the core 1021 and enters the clothing processing chamber 10a, and extends in a direction away from the rotation axis of the clothing processing drum 10, enters the lifting rib 14 and is connected to the receiving circuit board 133, and the second sub-segment connects the receiving circuit board 133 and the electrical component.

[0126] In an embodiment in which the receiving circuit board 133 and the receiving coil 131 are integrated in the bracket 132, the receiving circuit board 133 and the receiving coil 131 are arranged on the side of the back cover 102 away from the barrel body 101, one end of the cable 19 is connected to the receiving circuit board 133, and the other end passes through the lead-in opening 102a on the core 1021 to enter the clothing processing chamber 10a, and extends in the direction of the rotation axis away from the clothing processing barrel 10, enters the lifting rib 14 and is connected to the electrical components.

[0127] In this embodiment, the lead-in port 102a is arranged on the core 1021, which can reduce the probability of the cable 19 being wound on the side of the rear cover 102 away from the barrel body 101. In addition, the cable 19 is passed through the core 1021, which can also increase the stability of the cable 19 when it rotates with the clothing processing barrel 10, thereby increasing the wiring reliability.

[0128] In some further embodiments, the lead-in opening 102 a is located in a spacing area between two adjacent support arms 1023 .

[0129] In this embodiment, the space between the two support arms 1023 can be fully utilized for the cable 19 to pass through, and the lead-in port 102 a has sufficient arrangement space to facilitate the cable 19 to pass through.

[0130] The specific structure of the bracket 132 is not limited.

[0131] For some examples, see Figure 7 The bracket 132 includes an annular portion 1321, a connecting portion 1322 and an extending structure 1323. The connecting portion 1322 and the extending structure 1323 are respectively connected to the annular portion 1321. The receiving coil 131 is arranged on the annular portion 1321. The connecting portion 1322 is connected to the back cover 102. The extending structure 1323 is arranged on a side of the support arm 1023 away from the clothing processing chamber 10a. The receiving circuit board 133 is arranged on the extending structure 1323.

[0132] In this embodiment, the extension structure 1323 provides space for the receiving circuit board 133 , and the support arm 1023 provides support for the extension structure 1323 , thereby increasing the installation stability of the receiving circuit board 133 .

[0133] The annular portion 1321 can be arranged on the side of the core 1021 facing the rear plate 111, that is, the annular portion 1321 can be roughly arranged in the central area of ​​the rear cover 102. In this way, the receiving coil 131 can also be roughly arranged in the central area of ​​the rear cover 102, so that the receiving coil 131 can be coaxially arranged with the clothing processing drum 10. The core 1021 has sufficient installation space to set the annular portion 1321, thereby increasing the movement stability of the receiving coil 131.

[0134] It is understandable that in the embodiment where the receiving coil 131 and the receiving circuit board 133 are spaced apart, the receiving coil 131 may also be supported on the bracket 132 and connected to the laundry processing drum 10 through the bracket 132. Figure 7 In this case, the bracket 132 may be provided with an extension structure, see Figure 8 , the bracket 132 may also not be provided with an extension structure.

[0135] For some examples, see Figure 1 and Figure 8 The annular portion 1321 is formed with a second annular groove 1321 a , the second annular groove 1321 a is open toward one side of the rear plate 111 , and the receiving coil 131 is accommodated in the second annular groove 1321 a .

[0136] Specifically, the second annular groove 1321a is an annular space defined by the structure of the annular portion 1321. The second annular groove 1321a is open toward the side of the rear plate 111, which facilitates 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 closed to provide support for the receiving coil 131 and reduce the probability of the receiving coil 131 detaching from the second annular groove 1321a.

[0137] The specific structure of the annular portion 1321 is not limited.

[0138] For some examples, see Figure 7 and Figure 8 The annular portion 1321 includes a second annular plate 13211, a second inner annular wall 13212 and a second outer annular wall 13213. The second inner annular wall 13212 is arranged at the radial inner edge of the second annular plate 13211, and the second outer annular wall 13213 is arranged at the radial outer edge of the second annular plate 13211. The interval between the second inner annular wall 13212 and the second outer annular wall 13213 forms a second annular groove 1321a.

[0139] Specifically, when the receiving coil 131 cooperates with the annular portion 1321, the receiving coil 131 surrounds the circumferential outer side of the second inner annular wall 13212 and is located on the circumferential inner side of the second outer annular wall 13213, and one end of the receiving coil 131 along the axial direction abuts against the second ring plate 13211, so as to achieve docking between the receiving coil 131 and the annular portion 1321.

[0140] The connection portion 1322 is disposed on the radially outer side of the second outer annular wall 13213 , or the connection portion 1322 is disposed on the radially inner side of the second inner annular wall 13212 .

[0141] That is, one end of the connecting portion 1322 may be connected to the second outer annular wall 13213 or the second inner annular wall 13212, and the other end of the connecting portion 1322 may be connected to the rear cover 102 to achieve the connection between the bracket 132 and the rear cover 102. Figure 7 The connection portion 1322 is disposed radially inward of the second inner annular wall 13212. In this way, the probability that the connection portion 1322 affects the air intake of the laundry processing tub 10 at the rear cover 102 can be reduced.

[0142] In this embodiment, the receiving coil 131 is conveniently connected to the annular portion 1321, and the receiving coil 131 can be easily disassembled and inspected. The annular portion 1321 has a simple structure, which can reduce the manufacturing requirements for the bracket 132. The setting position of the connecting portion 1322 can also reduce the probability of interference with the receiving coil 131, thereby facilitating the relative arrangement of the receiving coil 131 and the transmitting coil 121.

[0143] The connection portion 1322 may be detachably connected to the back cover 102 . For example, the connection portion 1322 may be connected to the back cover 102 by screws, which is not limited herein.

[0144] In some embodiments, the electrical component includes a detection unit 15 , which is used to detect the conductivity of the clothes in the clothes processing drum 10 . The detection unit 15 is electrically connected to the receiving module 13 .

[0145] The detection unit 15 can detect the conductivity of the load such as clothes in the clothes processing chamber 10a. The clothes processing device 1 can judge the degree of drying according to the conductivity detected by the detection unit 15. Exemplarily, the detection principle of the detection unit 15 can be: the load such as clothes in the clothes processing chamber 10a contacts the two detection electrodes 151 of the detection unit 15, so that the detection circuit of the detection unit 15 is turned on, and the resistance values ​​of the load such as clothes with different moisture levels are different, that is, the moisture level of the load such as clothes is related to the conductivity, and the degree of drying is judged according to the conductivity.

[0146] In this embodiment, the detection unit 15 is arranged in the clothing processing drum 10, and the receiving module 13 provides electrical energy to the detection unit 15. The detection electrode 151 of the detection unit 15 can contact the load such as clothing in the clothing processing chamber 10a, thereby sensing the drying degree of the clothing at a close distance, and effectively improving the accuracy of judging the dryness degree of the load such as clothing in the clothing processing drum 10.

[0147] The installation position of the detection unit 15 on the lifting rib 14 is not limited.

[0148] In some embodiments, the receiving circuit board 133 is disposed in the lifting rib 14 , and the detection unit 15 includes a detection electrode 151 and a detection circuit. The detection electrode 151 is disposed on the outer surface of the lifting rib 14 , and the detection circuit is disposed in the lifting rib 14 and electrically connected to the receiving circuit board 133 .

[0149] Specifically, see Fig.14 The detection electrode 151 is arranged on the outer surface of the lifting rib 14, which is convenient for close contact with loads such as clothes. The detection circuit is arranged in the lifting rib 14, that is, the lifting rib 14 can be used to move the clothes in the clothing processing chamber 10a, and at the same time, it can also provide an installation space for the detection circuit, which reduces the probability of the detection circuit contacting the clothes to a certain extent, and increases the installation and working reliability of the detection unit 15.

[0150] In this embodiment, the receiving circuit board 133 is disposed in the lifting rib 14, which can facilitate the connection between the detection circuit and the receiving circuit board 133 and provide a stable power supply.

[0151] Exemplarily, the detection electrode 151 may be entirely located on the circumferential outer surface of the lifting rib 14, or part of the detection electrode 151 may be located on an outer side surface of the lifting rib 14 along the circumferential direction, and the other part may be located on the top side surface of the lifting rib 14 radially away from the circumferential side wall of the clothing processing drum 10.

[0152] The specific structure of the detection electrode 151 is not limited.

[0153] For example, see Figures 14 to 16 , the detection electrode 151 includes a first electrode member and a second electrode member, both of which are located on the outer surface of the lifting rib 14, and the first electrode member includes a first connection structure 1511 and at least two first teeth 1512 connected to the first connection structure 1511. The second electrode member includes a second connection structure 1513 and at least two second teeth 1514 connected to the second connection structure 1513, and the first teeth 1512 and the second teeth 1514 are arranged alternately. In other words, there is a second tooth 1514 between any two adjacent first teeth 1512, and the distance between the first tooth 1512 and the second tooth 1514 is greater than zero.

[0154] In this embodiment, the first teeth 1512 and the second teeth 1514 are alternately arranged to form a fork structure, one first tooth 1512 and one second tooth 1514 form an electrode pair, the detection electrode 151 has at least two electrode pairs, the clothes are in contact with at least two electrode pairs, each electrode pair is conductive and can be regarded as a resistor, at least two electrode pairs can be regarded as at least two resistors in parallel, so that the detection of conductivity changes is more sensitive, the detection accuracy and sensitivity of the detection electrode 151 are improved, and the problems of incomplete drying or over-drying are reduced to a certain extent, thereby improving the drying performance.

[0155] The specific structural form of the first tooth 1512 is not limited, and can be in the form of a sheet or a column, etc. The specific structural form of the second tooth 1514 is not limited, and can be in the form of a sheet or a column, etc. Among them, the cross-sectional shape of the column is not limited, and can be a circle or a polygon, etc. The polygon is, for example, a quadrilateral, a pentagon, etc. It can be understood that the polygon can include a rounded polygon.

[0156] For some examples, see Fig.15 , the first connection structure 1511 and the second connection structure 1513 are linearly extended in parallel, and all the first teeth 1512 and all the second teeth 1514 are located between the first connection structure 1511 and the second connection structure 1513. In other words, the first connection structure 1511 and the second connection structure 1513 can be substantially a straight line structure or a curved line structure.

[0157] Exemplarily, the shape of the first tooth 1512 is substantially the same as that of the second tooth 1514 , the first tooth 1512 is substantially parallel to the second tooth 1514 , and the first connecting structure 1511 and the second connecting structure 1513 are both linear structures and substantially parallel.

[0158] In this embodiment, the first electrode member and the second electrode member have simple and compact structures and neat and beautiful appearances.

[0159] For some examples, see Fig.17 The first electrode member and the second electrode member are roughly in the same plane. In this way, the first electrode member and the second electrode member are roughly flat, occupying a smaller space, thus saving space in the clothing processing drum 10.

[0160] The first electrode member and the second electrode member are both made of conductive material. For example, the first electrode member and the second electrode member are both made of metal material.

[0161] For some examples, see Fig.14 and Fig.15, the first tooth 1512 protrudes in a direction away from the lifting rib 14 to form a first protrusion 1512a. The first protrusion 1512a can not only enhance the structural strength of the first tooth 1512, but also facilitate contact with clothing and increase the contact area with clothing. The first protrusion 1512a can be in a convex arc shape. The surface of the first protrusion 1512a away from the lifting rib 14 is an arc surface.

[0162] For some examples, see Fig.14 and Fig.15 , the part of the second tooth 1514 protrudes in the direction away from the lifting rib 14 to form a second protrusion 1514a. The second protrusion 1514a can not only enhance the structural strength of the second tooth 1514, but also facilitate contact with clothing and increase the contact area with clothing. The second protrusion 1514a can be in a convex arc shape. The surface of the second protrusion 1514a away from the lifting rib 14 is an arc surface.

[0163] In some examples, the surface of the first tooth 1512 away from the lifting rib 14 is an arc surface. The surface of the first tooth 1512 away from the lifting rib 14 needs to contact with the clothes, and the arc surface can avoid hooking the clothes to a certain extent, reducing the mutual wear between the clothes and the first tooth 1512.

[0164] In some examples, the surface of the second teeth 1514 away from the lifting ribs 14 is an arc surface. The surface of the second teeth 1514 away from the lifting ribs 14 needs to contact with the clothes, and the arc surface can avoid hooking the clothes to a certain extent, reducing the mutual wear between the clothes and the second teeth 1514.

[0165] For some examples, see Fig.16 The detection electrode 151 includes a first terminal 1515 and a second terminal 1516. The first terminal 1515 is connected to the first electrode member, and the second terminal 1516 is connected to the second electrode member. The first terminal 1515 and the second terminal 1516 both extend into the lifting rib 14 and are electrically connected to the detection circuit.

[0166] For example, the first terminal 1515 is connected to one of the first teeth 1512 , and the second terminal 1516 is connected to one of the second teeth 1514 .

[0167] In this embodiment, the first terminal 1515 and the second terminal 1516 are connected to the detection circuit to transmit an electrical signal between the detection circuit and the detection electrode 151. The first terminal 1515, the second terminal 1516 and the detection circuit are all located in the lifting rib 14, which reduces the probability of the first terminal 1515, the second terminal 1516 and the detection circuit contacting the clothing, thereby improving safety.

[0168] In some embodiments, the first electrode member may be an integrally formed structure, that is, the first connection structure 1511 and the first teeth 1512 may be integrally formed and manufactured.

[0169] In some embodiments, the first electrode member and the first terminal 1515 may be an integrally formed structure.

[0170] In some embodiments, the second electrode member may be an integrally formed structure, that is, the second connection structure 1513 and the second teeth 1514 may be integrally formed and manufactured.

[0171] In some embodiments, the second electrode member and the second terminal 1516 may be an integrally formed structure.

[0172] For some examples, see Figure 1 and Fig.18 The laundry processing device 1 includes a housing 11 , the housing 11 includes a rear plate 111 located at the rear side of the laundry processing tub 10 , and the transmitting module 12 is disposed on the rear plate 111 .

[0173] Specifically, the housing 11 is an appearance component of the clothes processing device 1 , and can protect the clothes processing drum 10 inside.

[0174] It should be noted that the rear plate 111 refers to the component of the housing 11 located at the rear side of the laundry processing device 1 along the front-to-back direction. The rear side is the side of the laundry processing device 1 that is away from the user after installation. Exemplarily, the radial edge of the rear cover 102 is dynamically sealed with the inner surface of the rear plate 111. That is, the laundry processing drum 10 is sealed and connected to the rear plate 111, and the laundry processing drum 10 can rotate relative to the rear plate 111.

[0175] It should be noted that the transmitting module 12 is arranged on the back plate 111. The transmitting module 12 as a whole may be an integrated component, which is arranged on the side of the back plate 111 facing the back cover 102 or the side of the back plate 111 away from the back cover 102; or the various components of the transmitting module 12 are dispersedly arranged at different positions of the back plate 111, for example, some of the components are arranged on the side of the back plate 111 facing the back cover 102, and other parts are arranged on the side of the back plate 111 away from the back cover 102.

[0176] In this embodiment, the transmitting module 12 is arranged on the rear plate 111, which provides sufficient installation space and installation safety for the transmitting module 12, while shortening the distance between the transmitting module 12 and the receiving module 13, thereby increasing the power transmission performance. At the same time, it can also reduce the probability of the electrical connection between the transmitting module 12 and the main control board interfering with the clothing processing drum 10, thereby increasing the reliability of the electrical connection between the transmitting module 12 and the main control board.

[0177] In some embodiments, the transmitting module 12 includes a transmitting circuit board 123 , and the transmitting circuit board 123 is electrically connected to the transmitting coil 121 .

[0178] Exemplarily, the transmitting circuit board 123 includes a power supply circuit, which can realize power transmission to the receiving module 13 .

[0179] Of course, the transmitting circuit board 123 may also include a modulation and demodulation circuit, which can realize signal conversion, that is, the clothing information detected by the electrical components can be transmitted to the receiving module 13, and the receiving module 13 then passes the information to the transmitting module 12.

[0180] See also Fig. 9 and Fig.10 , the transmitting coil 121 is arranged on the side of the rear plate 111 facing the laundry treatment drum 10, that is, the transmitting coil 121 is arranged on the front side of the rear plate 111, and the transmitting coil 121 can be arranged close to the receiving coil 131, reducing the distance between the transmitting coil 121 and the receiving coil 131, so as to achieve effective and sufficient power transmission. Moreover, in this embodiment, the transmitting coil 121 and the receiving coil 131 can be arranged along the axial direction of the laundry treatment drum 10. During the rotation of the laundry treatment drum 10, no matter where the receiving coil 131 rotates with the laundry treatment drum 10, the receiving coil 131 and the transmitting coil 121 can always maintain a relative state, so that the receiving coil 131 can continuously and stably receive the power transmitted by the transmitting coil 121, so as to achieve effective and sufficient power supply.

[0181] The transmitting circuit board 123 is arranged on the side of the rear plate 111 away from the clothes processing drum 10, that is, the transmitting circuit board 123 is arranged on the rear side of the rear plate 111. The rear plate 111 can play a certain protective role for the transmitting circuit board 123, reduce the probability of the airflow and the impurities such as hair scraps carried by the airflow being adsorbed on the transmitting circuit board 123, and increase the installation safety of the transmitting circuit board 123. At the same time, it can also facilitate the wired connection between the transmitting circuit board 123 and the main control board.

[0182] For some examples, see Fig. 9 The transmitting module 12 includes a supporting frame 122 , and a transmitting coil 121 and a transmitting circuit board 123 are integrated on the supporting frame 122 .

[0183] In this embodiment, the transmitting coil 121 and the transmitting circuit board 123 are integrated by the support frame 122, and there is no need to connect the transmitting coil 121 and the transmitting circuit board 123 by wires, which reduces the high assembly complexity caused by the interlacing of wires, makes power transmission more convenient, reduces power loss and electromagnetic interference, and the transmitting coil 121 and the transmitting circuit board 123 are arranged on the same plane. The overall structure of the transmitting module 12 is simple and compact, and the installation and maintenance of each component are convenient. The support frame 122 can provide installation support for the transmitting coil 121 and the transmitting circuit board 123, and increase the installation stability of the transmitting coil 121 and the transmitting circuit board 123.

[0184] Of course, in the embodiment where the transmitting coil 121 and the transmitting circuit board 123 are spaced apart, the transmitting coil 121 may also be supported on the support frame 122 , that is, the connection with components outside the laundry processing drum 10 is achieved through the support frame 122 .

[0185] The specific structure of the support frame 122 is not limited.

[0186] For some examples, see Fig. 9 and Fig.11 The support frame 122 includes an annular body 1221 and a connecting ear 1222 connected to the annular body 1221 . The transmitting coil 121 is disposed on the annular body 1221 , and the connecting ear 1222 is connected to the rear plate 111 .

[0187] In this embodiment, the annular body 1221 provides an installation space for the transmitting coil 121, and the connecting ear 1222 is connected to the rear plate 111. The annular body 1221 and the connecting ear 1222 are used to stabilize the installation position of the transmitting coil 121 in the clothing processing device 1, thereby reducing the probability of damage to the transmitting coil 121 and increasing the working stability of the transmitting coil 121.

[0188] For some examples, see Fig. 9 and Fig.11 The annular body 1221 is formed with a first annular groove 1221a, the first annular groove 1221a is open toward one side of the laundry processing tub 10, and the transmitting coil 121 is accommodated in the first annular groove 1221a.

[0189] Specifically, the first annular groove 1221a is an annular space defined by the structure of the annular body 1221. The first annular groove 1221a is open toward the side of the laundry treatment drum 10, so as to facilitate the relative arrangement of the transmitting coil 121 and the receiving coil 131 and realize effective power transmission. The side of the first annular groove 1221a toward the rear plate 111 can be closed to provide support for the transmitting coil 121 and reduce the probability of the transmitting coil 121 being separated from the first annular groove 1221a.

[0190] The specific structure of the annular body 1221 is not limited.

[0191] For some examples, see Fig. 9 and Fig.11 The annular body 1221 includes a first annular plate 12211, a first inner annular wall 12212 and a first outer annular wall 12213. The first inner annular wall 12212 is arranged at the radial inner edge of the first annular plate 12211, and the first outer annular wall 12213 is arranged at the radial outer edge of the first annular plate 12211. The interval between the first inner annular wall 12212 and the first outer annular wall 12213 forms a first annular groove 1221aa.

[0192] Specifically, when the transmitting coil 121 cooperates with the annular body 1221, the transmitting coil 121 surrounds the circumferential outer side of the first inner annular wall 12212 and is located on the circumferential inner side of the first outer annular wall 12213, and one end of the transmitting coil 121 along the axial direction abuts against the first annular plate 12211, so as to achieve the docking of the transmitting coil 121 and the annular body 1221.

[0193] The connecting ear 1222 is arranged on the radial outer side of the first outer annular wall 12213 , or the connecting ear 1222 is arranged on the radial inner side of the first inner annular wall 12212 .

[0194] That is, one end of the connecting ear 1222 can be connected to the first outer annular wall 12213 or the first inner annular wall 12212, and the other end of the connecting ear 1222 is connected to the rear plate 111 to achieve the connection between the support frame 122 and the rear plate 111. For example, please refer to Fig.11 The connecting ear 1222 is arranged on the radial outside of the first outer ring wall 12213 , so that the connecting ear 1222 can have sufficient extension space to achieve a stable connection with the rear plate 111 .

[0195] In this embodiment, the transmitting coil 121 is conveniently connected to the annular body 1221, and the transmitting coil 121 can be easily disassembled, assembled and inspected. The annular body 1221 has a simple structure, which can reduce the manufacturing requirements for the support frame 122. The location of the connecting ear 1222 can also reduce the probability of interference with the transmitting coil 121, thereby facilitating the relative arrangement of the transmitting coil 121 and the receiving coil 131.

[0196] The connecting ear 1222 can be detachably connected to the rear plate 111. For example, the connecting ear 1222 can be connected to the rear plate 111 by screws, which is not limited here.

[0197] Exemplarily, the transmitting coil 121 and the receiving coil 131 are substantially ring-shaped structures.

[0198] Exemplarily, the transmitting coil 121 is disposed opposite to the receiving coil 131. In this way, the influence of the rotating laundry treatment drum 10 on the transmitting coil 121 is reduced, and the installation safety is increased.

[0199] It should be noted that the transmitting coil 121 and the receiving coil 131 are arranged relative to each other, which means that there is a certain interval between the transmitting coil 121 and the receiving coil 131, and taking the plane perpendicular to the front-back direction as the projection plane, the projection of the transmitting coil 121 at least partially overlaps with the projection of the receiving coil 131. Exemplarily, the transmitting coil 121 and the receiving coil 131 are coaxially arranged.

[0200] It should be noted that the transmitting coil 121 and the receiving coil 131 can always remain coaxial and relatively arranged, that is, no matter where the laundry treatment drum 10 rotates to, the transmitting coil 121 and the receiving coil 131 always remain coaxial and relatively arranged. The transmitting coil 121 and the receiving coil 131 can also be coaxial and relatively arranged at a specific position, that is, the receiving coil 131 can move to the specific position with the rotation of the laundry treatment drum 10 and be coaxial and relatively arranged with the transmitting coil 121.

[0201] In some embodiments, the receiving module 13, the transmitting module 12 and the laundry treatment drum 10 are coaxially arranged. That is, when the laundry treatment drum 10 drives the receiving module 13 to rotate, the receiving module 13 can still continue to receive the electric energy transmitted by the transmitting module 12 to power the electrical components.

[0202] Exemplarily, the transmitting coil 121, the receiving coil 131, and the laundry treatment drum 10 are coaxially arranged. That is, no matter where the laundry treatment drum 10 rotates to, the transmitting coil 121 and the receiving coil 131 always remain coaxial and relative to each other to achieve continuous transmission of electrical energy. In this embodiment, the transmitting coil 121 and the transmitting circuit board 123 can be dispersedly arranged or integrated on the support frame 122, and the receiving coil 131 and the receiving circuit board 133 can be dispersedly arranged or integrated on the support frame 132, without limitation here.

[0203] The distance between the transmitting coil 121 and the receiving coil 131 is not limited.

[0204] In some embodiments, the distance between the transmitting coil 121 and the receiving coil 131 is 4 mm (millimeter) to 15 mm, for example, 4 mm, 4.5 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, etc.

[0205] It should 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 along the axial direction when the transmitting coil 121 and the receiving coil 131 are arranged relative to each other.

[0206] 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 will need 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 clothes processing drum will be smaller, which will easily increase the probability of interference between the transmitting coil and the clothes processing drum, and increase the probability of damage to the transmitting coil.

[0207] In this embodiment, the distance between the transmitting coil 121 and the receiving coil 131 is neither too large nor too small, and there is a sufficient safety distance between the transmitting coil 121 and the clothing processing 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 requirements of the electrical components.

[0208] In some embodiments, the distance between the transmitting coil 121 and the receiving coil 131 is 5.5 mm to 10 mm, for example, 5.5 mm, 5.7 mm, 6 mm, 6.2 mm, 6.6 mm, 7 mm, 7.4 mm, 8 mm, 8.6 mm, 9 mm, 9.3 mm, 9.8 mm, 10 mm, etc.

[0209] In this embodiment, the distance between the transmitting coil 121 and the receiving coil 131 is more appropriate, the probability of rotational interference between the transmitting coil 121 and the clothing processing drum 10 is small, and the transmitting coil 121 can provide sufficient working current for the receiving coil 131, thereby increasing the reliability of wireless power transmission of the clothing processing device 1.

During the rotation of the laundry treatment drum 10, the transmitting coil 121 and the receiving coil 131 can always be arranged relative to each other to achieve continuous power transmission.

[0215] Third embodiment: Please refer to Fig. 20 The transmitting coil 121 is arranged on the side of the rear plate 111 facing the rear cover 102, the transmitting circuit board 123 is arranged between the rear cover 17 and the rear plate 111, the receiving coil 131 is arranged on the side of the rear cover 102 facing the rear plate 111, and the receiving circuit board 133 is arranged on the side of the rear cover 102 facing the rear plate 111. The transmitting coil 121, the receiving coil 131 and the clothing processing drum 10 are coaxially arranged.

[0216] In this embodiment, the transmitting coil 121 and the transmitting circuit board 123 are dispersedly arranged, and the receiving coil 131 and the receiving circuit board 133 can be integrated on the bracket 132. During the rotation of the laundry treatment drum 10, the transmitting coil 121 and the receiving coil 131 can always be arranged relative to each other to achieve continuous power transmission.

[0217] Exemplarily, the clothes processing drum 10 includes an air inlet and an air outlet, the clothes processing chamber 10a is connected to the air inlet and the air outlet, the air inlet is arranged on the rear cover 102, and the clothes processing device 1 includes a base 16, the base 16 is arranged below the clothes processing drum 10, and the base 16 has a drying channel, and the drying channel is connected to the air outlet. The clothes processing device 1 also includes a rear cover 17, and the rear side wall of the rear plate 111 is formed with a return air port and an air supply port connected to the air inlet, and the height of the return air port is lower than the height of the air supply port. The two ends of the drying channel are connected to the air outlet and the return air port respectively. The rear cover 17 is arranged around the air supply port and the return air port, and defines an air supply channel together with the rear side wall of the rear plate 111 of the box body 11. The drying channel and the air supply channel together constitute a circulating air channel. The drying channel is located upstream of the air supply channel along the air flow direction in the circulating air channel, and the air flow flows through the air outlet, the drying channel, the return air port, the air supply channel, the air supply port and the air inlet in sequence.

[0218] The number of air supply outlets is not limited, and the air supply outlet can be one or more, for example, the number of air supply outlets is two, three, four or five, etc.

[0219] In some embodiments, the clothing processing device 1 further includes a heat exchange component located in the drying tunnel, and the heat exchange component is used to exchange heat with the airflow in the drying tunnel, thereby dehumidifying and heating. The humid hot airflow in the clothing processing drum 10 can enter the drying tunnel through the air outlet, and after heat exchange with the heat exchange component, it is converted into a dry hot airflow, and the dry hot airflow enters the air supply channel through the return air port, and then flows back to the clothing processing chamber 10a through the air supply port and the air inlet.

[0220] In some embodiments, the heat exchange component includes a condenser and an evaporator, and the clothing processing device 1 also includes a compressor and a throttling device. The compressor, condenser, throttling device and evaporator are connected through pipelines to form a heat pump system, and the 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 a dry hot airflow. The evaporator is used to cool and dehumidify the humid hot airflow from the clothing processing chamber 10a to form a dry cold airflow; the condenser heats the dry cold airflow into a dry hot airflow and refluxes it into the clothing processing chamber 10a.

[0221] 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 state and discharges it. The discharged 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, and becomes a low-pressure and low-temperature gas-liquid two-phase mixture and enters the evaporator; the refrigerant in the evaporator absorbs the heat of the airflow and becomes a low-pressure gaseous state, and the low-pressure gaseous refrigerant is sucked in by the compressor again; this cycle is repeated to achieve heat exchange. In other words, the evaporator is used to cool and dehumidify the humid hot airflow from the clothing processing chamber 10a to form a dry cold airflow, and the condenser heats the dry cold airflow into a dry hot airflow and then flows back into the clothing processing chamber 10a. The dry hot airflow flowing back to the clothing processing chamber 10a contacts the wet clothes to form a humid hot airflow again, completing a drying cycle. By repeatedly running the drying cycle, the circulating airflow is continuously provided to the clothing processing chamber 10a to dry the clothes.

[0222] Exemplarily, both the evaporator and the condenser may be fin-tube heat exchangers.

[0223] Exemplarily, the throttling device includes but is not limited to an electronic expansion valve and the like.

[0224] In some examples, the clothing processing device 1 further includes an impeller, which is used to drive the airflow. For example, the impeller is located in the drying tunnel and between the heat exchange component and the return air outlet. In the process of drying clothes, the impeller is used to drive the airflow passing 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 speed up the airflow and improve the drying efficiency.
