[0057] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0058] The various specific technical features described in the specific embodiments can be combined in any suitable manner without contradiction, for example, different embodiments and technical solutions can be formed by combining different specific technical features. In order to avoid unnecessary repetition, various possible combinations of the specific technical features in the present invention will not be described separately.

[0059] In the following description, the terms "first\second\..." are only used to distinguish different objects, and do not mean that the objects have the same or related points. It should be understood that the directions "above", "below", "outside" and "inside" are all directions in normal use, and the directions "left" and "right" refer to the left and right directions shown in the specific corresponding schematic diagrams, which may be the left and right directions in normal use or not.

[0060] It should be noted that the terms "comprises", "includes" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element. "Multiple" means greater than or equal to two.

[0061] The present application embodiment provides a clothes processing device 1, see Figures 1 to 22 The laundry processing device 1 includes a laundry processing drum 10 and a wireless power supply component.

[0062] 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.

[0063] The laundry treatment tub 10 has a laundry treatment chamber 10a.

[0064] 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 inlet, through which the user puts the laundry into or takes out the laundry treatment drum 10. During the rotation of the laundry treatment drum 10, the laundry is driven to move from the bottom to the top, and the laundry falls from the top to the bottom under the action of gravity, so that the laundry is dispersed, thrown and changes its posture under the combined action of the laundry treatment drum 10 and gravity.

[0065] It is understandable that the laundry treatment drum 10 may be a single drum structure, that is, the laundry treatment device 1 has only one drum body, namely, the laundry treatment drum 10. Of course, in other examples, the laundry treatment device 1 may further include an outer drum, which is disposed on the outer side of the laundry treatment drum 10 in the circumferential direction.

[0066] The embodiment of the present application is described by taking the clothing processing device 1 adopting a single-drum structure as an example.

[0067] 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.

[0068] 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.

[0069] For example, see Figure 1 and Figure 2 The wireless power supply component includes a transmitting module 12 and a receiving module 13 . The transmitting module 12 is arranged on a component outside the clothing processing drum 10 , and the receiving module 13 is arranged in the clothing processing drum 10 .

[0070] It should be noted that the components outside the clothing processing drum 10 refer to components that are independent of the clothing processing drum 10 and are arranged on the outside of the clothing processing drum 10. When the clothing processing drum 10 rotates, the transmitting module 12 is stationary relative to the clothing processing drum 10. For example, it can be the box body 11, the base 16 arranged under the box body 11, etc., and there is no limitation here.

[0071] It should be noted that the transmitting module 12 is arranged on a component outside the clothing processing drum 10. The various components of the transmitting module 12 can be integrated together and arranged as a whole on a component outside the clothing processing drum 10. Alternatively, the various components of the transmitting module 12 can be dispersedly arranged on different components outside the clothing processing drum 10 or on different parts of the same component. There is no limitation here.

[0072] The receiving module 13 is arranged on the clothing processing drum 10. The receiving module 13 may be arranged on the clothing processing drum 10 or a component arranged in the clothing processing drum 10. During the operation of the clothing processing device 1, the rotation of the clothing processing drum 10 can drive the receiving module 13 to rotate synchronously.

[0073] It should be noted that the receiving module 13 is arranged in the clothing processing drum 10. The various components of the receiving module 13 can be integrated together and arranged in the clothing processing drum 10 as a whole, or the various components of the receiving module 13 can be dispersedly arranged in different positions of the clothing processing drum 10, and no limitation is made here.

[0074] Exemplarily, the transmitting module 12 includes a transmitting coil 121 and a transmitting circuit board 123, and the transmitting coil 121 is electrically connected to the transmitting circuit board 123. The receiving module 13 includes a receiving coil 131 and a receiving circuit board 133, and the receiving coil 131 is electrically connected to the receiving circuit board 133, and the receiving coil 131 is used to receive the electromagnetic signal transmitted by the transmitting coil 121 and generate an induced current.

[0075] Exemplarily, the transmitting module 12 can be electrically connected to the main control board of the clothes processing device 1 through the transmitting circuit board 123. The main control board is used to control the operation of the clothes processing device 1 and supply power to various parts in the clothes processing device 1 so that the circuits of each part can work normally to achieve functions such as drying control. Exemplarily, the transmitting circuit board 123 is electrically connected to the main control board through a cable to receive the power supplied by the main control board, so that the transmitting coil 121 can transmit electromagnetic signals.

[0076] The transmitting module 12 is wirelessly connected to the receiving module 13 , that is, the transmitting module 12 can transmit power to the receiving module 13 wirelessly.

[0077] The transmitting module 12 and the receiving module 13 can be wirelessly connected by electromagnetic induction.

[0078] Specifically, the transmitting coil 121 generates a changing magnetic field, the receiving coil 131 generates an induced current through electromagnetic induction, receives the power transmission from the transmitting coil 121, and the receiving circuit board 133 is electrically connected to the receiving coil 131 to output power.

[0079] In this way, the electrical components disposed in the laundry processing drum 10 can be electrically connected to the receiving circuit board 133, and the receiving circuit board 133 can be used to supply power to the electrical components to meet the power demand.

[0080] 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.

[0081] The electrical components may include a unit for detecting the state of clothes and other units with specific functions that can improve the drying performance. Exemplarily, the unit for detecting the state of clothes may be a unit for detecting the temperature, conductivity, etc. of the clothes.

[0082] It can be understood that the receiving module 13 is arranged in the clothes processing drum 10, and the electrical components such as the unit for detecting the state of clothes can be arranged in the clothes processing drum 10 and electrically connected to the receiving module 13 to obtain electric energy. When the clothes processing drum 10 rotates, the receiving module 13 and the electrical components rotate synchronously, and the electrical connection between the receiving module and the electrical components is relatively stable. The receiving module 13 can also receive the electric energy transmitted from the transmitting module 12 during the rotation process. In this way, the electrical components arranged in the clothes processing drum 10 can sense the state of clothes at a close distance and perform specific functions to improve the working performance of the clothes processing device 1. For example, the dryness judgment performance of the clothes processing device 1 can be improved.

[0083] Exemplarily, the transmitting circuit board 123 includes a modulation and demodulation circuit and a power supply circuit. The modulation and demodulation circuit can realize signal conversion, and the power supply circuit can realize power transmission to the receiving module 13.

[0084] Exemplarily, the receiving circuit board 133 includes a modulation and demodulation circuit and a power output circuit. The modulation and demodulation circuit can realize signal conversion, and the power output circuit can realize the output of electric energy.

[0085] That is to say, in addition to transmitting electrical energy, the transmitting module 12 and the receiving module 13 can also realize signal transmission, 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.

[0086] Of course, in other embodiments, the transmitting module 12 and the receiving module 13 may also only transmit electrical energy, and the clothing processing device 1 may be provided with a wireless transmission unit. The receiving module 13 can provide electrical energy for the wireless transmission unit, and the wireless transmission unit can receive the clothing information detected by the electrical components and transmit it wirelessly.

[0087] 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.

[0088] In the laundry 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, realize the electric energy transmission between the relatively rotating laundry processing drum 10 and the components outside the relatively stationary laundry processing drum 10, realize the electric energy transmission without wire connection, and have high reliability. In addition, the transmitting circuit board 123 can be connected to the main control board of the laundry processing device 1 to provide electric energy to the transmitting coil 121, so that the transmitting coil 121 can transmit electromagnetic signals to the receiving coil 131, and the receiving circuit board 133 can supply the received electric energy to the electrical components in the laundry processing drum 10, meet the power demand of the electrical components and facilitate the close-range perception of the state of the clothes, and improve the overall performance of the laundry processing device 1. The cooperation of the transmitting coil 121 and the transmitting circuit board 123, and the cooperation of the receiving coil 131 and the receiving circuit board 133 can make the transmission of electric energy more stable and reliable, output electric energy that meets the needs of the electrical components and assist in information transmission.

[0089] 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.

[0090] 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.

[0091] 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.

[0092] In some embodiments, 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.

[0093] The distance between the transmitting coil 121 and the receiving coil 131 is not limited.

[0094] 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.

[0095] 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.

[0096] 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.

[0097] 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.

[0098] 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.

[0099] 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.

[0100] The electrical connection method between the transmitting circuit board 123 and the transmitting coil 121 is not limited.

[0101] Exemplarily, in some embodiments, the transmitting circuit board 123 and the transmitting coil 121 are spaced apart and connected by a first connecting line, and the length of the first connecting line is less than 50 mm, 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.

[0102] In this embodiment, the transmitting circuit board 123 and the transmitting coil 121 are dispersedly arranged. On the one hand, the requirements for the installation space can be reduced. The transmitting circuit board 123 and the transmitting coil 121 can be arranged in a smaller area respectively, reducing the impact on the overall layout of the clothing processing device 1. On the other hand, the transmitting coil 121 can be arranged as close to the clothing processing drum 10 as possible to shorten the distance between the transmitting coil 131 and the receiving coil 131, so as to facilitate the transmission of sufficient electrical energy without increasing the required power. The transmitting circuit board 123 can be arranged as far away from the clothing processing drum 10 as possible to reduce the impact of the airflow and the hair debris carried by it, and increase the safety of the transmitting circuit board 123.

[0103] In addition, the length of the first connecting line is appropriate, that is, the distance between the transmitting circuit board 123 and the transmitting coil 121 can also be relatively reasonable, thereby reducing the probability of electromagnetic interference due to the long distance between the transmitting circuit board 123 and the transmitting coil 121 and reducing power loss, and the layout of the transmitting circuit board 123 and the transmitting coil 121 is highly reasonable.

[0104] The location where the transmitting coil 121 and the transmitting circuit board 123 are arranged at intervals is not limited.

[0105] For some examples, see Figures 1 to 4 The laundry processing device 1 comprises a housing 11, a laundry processing drum 10 is arranged in the housing 11, the housing 11 comprises a rear plate 111, a transmitting coil 121 is arranged on a side of the rear plate 111 facing the laundry processing drum 10. A transmitting circuit board 123 is arranged on a side of the rear plate 111 away from the laundry processing drum 10.

[0106] Specifically, the housing 11 is an appearance component of the clothes processing device 1 , and can protect the clothes processing drum 10 inside.

[0107] 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 end of the laundry processing drum 10 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.

[0108] In this embodiment, the transmitting coil 121 and the transmitting circuit board 123 are both arranged on the rear plate 111, which is convenient for shortening the connection distance between the transmitting coil 121 and the transmitting circuit board 123, reducing the probability of electromagnetic interference and reducing power loss.

[0109] 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. The transmitting coil 121 can be arranged close to the receiving coil 131 to reduce 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.

[0110] The transmitting circuit board 123 is arranged on the side of the rear plate 111 away from the clothes processing drum 10. 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.

[0111] For some examples, see Figure 1 and Fig.16 The clothing processing device 1 includes a rear cover 17, which is covered on the rear side surface of the rear plate 111 and defines an air supply channel together with the rear plate 111. The rear plate 111 has an air supply port, and the air flow in the air supply channel flows to the clothing processing chamber 10a through the air supply port. The transmitting circuit board 123 is arranged at a portion of the rear plate 111 that is not covered by the rear cover 17.

[0112] Specifically, the transmitting circuit board 123 is disposed at a portion of the rear side of the rear plate 111 that is not covered by the rear cover 17 , that is, the transmitting circuit board 123 is disposed at a portion of the rear plate 111 that is outside the rear cover 17 .

[0113] Exemplarily, the clothing processing drum 10 has an air inlet and an air outlet, and the clothing processing chamber 10a is connected to the air inlet and the air outlet. The dry hot air flow enters the clothing processing chamber 10a from the air inlet, and the humid hot air flow leaves the clothing processing chamber 10a from the air outlet. 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 that of the air supply port. The rear cover 17 is arranged around the air supply port and the return air port, and together with the rear side wall of the rear plate 111, defines an air supply channel. The air supply channel connects the return air port and the air supply port, and the dry hot air flows through the return air port, the air supply channel, and the air supply port into the clothing processing chamber 10a to dry the clothes.

[0114] In this embodiment, the transmitting circuit board 123 is arranged at a portion of the rear plate 111 that is not covered by the rear cover 17, which can reduce the impact of airflow on the transmitting circuit board 123, increase the installation stability of the transmitting circuit board 123, and also facilitate the electrical connection between the transmitting circuit board 123 and the main control board, reducing the difficulty of wiring.

[0115] Of course, in other embodiments, the transmitting circuit board 123 may also be disposed in the air supply channel, which is not limited here.

[0116] In some other embodiments, please refer to Figure 1 The clothing processing device 1 includes a voltage conversion module, which is used to convert alternating current into direct current.

[0117] The transmitting circuit board 123 is integrated on the voltage conversion module.

[0118] It is understandable that the voltage conversion module can be disposed on the rear plate 111 or other positions of the box body 11, and is not limited here.

[0119] The voltage conversion module can be connected to the main control board to convert alternating current into direct current.

[0120] In this embodiment, the transmitting circuit board 123 is integrated on the voltage conversion module. On the one hand, there is no need to provide additional installation space for the transmitting circuit board 123. The transmitting circuit board 123 and the voltage conversion module are integrated together, which saves installation space while also making the connection between the transmitting circuit board 123, the voltage conversion module and the main control board simpler, thereby increasing wiring stability.

[0121] In some other embodiments, please refer to Figure 1 , the laundry processing apparatus 1 includes a first bracket 122 .

[0122] The transmitting circuit board 123 and the transmitting coil 121 are integrated on the first bracket 122 .

[0123] In this embodiment, the transmitting coil 121 and the transmitting circuit board 123 are integrated by the first bracket 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 first bracket 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.

[0124] 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 first bracket 122 , that is, the connection with components outside the laundry treatment drum 10 is achieved through the first bracket 122 .

[0125] The specific structure of the first bracket 122 is not limited.

[0126] For some examples, see Figure 1 and Figure 5 The first bracket 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 .

[0127] 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.

[0128] For some examples, see Figure 1 and Figure 5 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.

[0129] 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.

[0130] The specific structure of the annular body 1221 is not limited.

[0131] For some examples, see Figure 1 and Figure 5 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 1221a.

[0132] 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.

[0133] 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 .

[0134] 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 first bracket 122 and the rear plate 111. Exemplarily, the connecting ear 1222 is arranged on the radially outer side of the first outer annular wall 12213, so that the connecting ear 1222 can have enough extension space to achieve a stable connection with the rear plate 111.

[0135] In this embodiment, the transmitting coil 121 is conveniently connected to the annular body 1221, and the transmitting coil 121 can be easily disassembled and inspected. The annular body 1221 has a simple structure, which can reduce the manufacturing requirements for the first bracket 122. The setting position 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.

[0136] 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.

[0137] In some embodiments, the receiving circuit board 133 and the receiving coil 131 are spaced apart and connected by a second connecting line, and the length of the second connecting line is less than 50 mm, 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.

[0138] In this embodiment, the receiving circuit board 133 and the receiving coil 131 are dispersedly arranged. On the one hand, the requirements for installation space can be reduced. The receiving coil 131 and the receiving circuit board 133 can be arranged in a smaller area respectively, reducing the impact on the overall layout of the clothing processing device 1. On the other hand, the receiving coil 131 can be located as much as possible at one end of the clothing processing drum 10 close to the rear plate 111 to shorten the distance between the receiving coil 121 and the transmitting coil 121, so as to facilitate the transmission of sufficient electrical energy without increasing the required power. The receiving circuit board 133 can be located in the space inside the clothing processing drum 10 to shorten the wiring distance between the electrical components and facilitate the provision of electrical energy.

[0139] In addition, the length of the second connecting line is appropriate, that is, the distance between the receiving circuit board 133 and the receiving coil 131 can also be relatively reasonable, thereby reducing the probability of electromagnetic interference due to the long distance between the receiving circuit board 133 and the receiving coil 131 and reducing power loss, and the layout of the receiving circuit board 133 and the receiving coil 131 is highly reasonable.

[0140] The receiving coil 131 may be installed at any position.

[0141] For some examples, see Figure 1 and Figure 2 The laundry processing drum 10 includes a drum body 101 and a rear cover 102 . The rear cover 102 is disposed at the rear end of the drum body 101 . The receiving coil 131 is disposed on a side of the rear cover 102 away from the drum body 101 .

[0142] Specifically, the front end 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.

[0143] In this embodiment, the receiving coil 131 is arranged on the side of the rear cover 102 away from the drum body 101, so that the receiving coil 131 does not contact the clothes in the clothing 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, it is also convenient to realize the relative arrangement of the receiving coil 131 and the transmitting coil 121 located outside the clothing processing drum 10, shortening the distance between the transmitting coil 121 and the receiving coil 131.

[0144] The location of the transmitting circuit board 123 is not limited.

[0145] For some examples, see Fig.10 The clothing processing device 1 includes a conical cap 18 , one end of which is connected to a side of the rear cover 102 close to the barrel 101 , and a receiving circuit board 133 is disposed in the conical cap 18 .

[0146] Specifically, the conical cap 18 is disposed on the laundry treatment drum 10, one end of the conical cap 18 is connected to the side of the rear cover 102 close to the drum body 101, and the other end extends toward the inner side of the drum body 101. The conical cap 18 can break up the laundry during the rotation of the laundry treatment drum 10, reduce the probability of the laundry being entangled or tangled, make the laundry dry more evenly, and improve the laundry drying effect.

[0147] For example, the conical cap 18 may be connected to the rear cover 102 at a location approximately in the center.

[0148] In this embodiment, the receiving circuit board 133 is arranged in the conical cap 18, and the conical cap 18 is used to provide an installation space for the receiving circuit board 133. The conical cap 18 can reduce the probability of the receiving circuit board 133 contacting clothing to a certain extent, thereby increasing the installation reliability of the receiving circuit board 133.

[0149] In some other embodiments, please refer to Fig.11 and Fig.13 The clothing processing device 1 includes a lifting rib 14 , which radially protrudes from the circumferential inner wall of the clothing processing chamber 10 a , and the receiving circuit board 133 is arranged in the lifting rib 14 .

[0150] 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.

[0151] Exemplarily, the lifting rib 14 may have a communication channel 14 a extending along the length direction of the lifting rib 14 , and the receiving circuit board 133 may be disposed in the communication channel 14 a .

[0152] In this embodiment, the lifting ribs 14 are used to provide installation space for the receiving circuit board 133, reducing the probability of the receiving circuit board 133 contacting the clothes and increasing the installation reliability of the receiving circuit board 133. Of course, electrical components can also be arranged in the lifting ribs 14, which is not limited here.

[0153] In this embodiment, the receiving circuit board 133 and the receiving coil 131 are separately arranged and arranged in the lifting rib 14, so as to shorten the wiring distance between the receiving circuit board 133 and the electrical components. The wire can pass through the lifting rib 14 to connect with the receiving circuit board 133, thereby increasing the reliability of power transmission.

[0154] In some other embodiments, please refer to Figure 6The back cover 102 includes a core 1021, a support arm 1023 and an outer ring structure 1022. The outer ring structure 1022 surrounds the circumferential outer side of the core 1021. A plurality of support arms 1023 are radially distributed along the circumference of the core 1021. The support arms 1023 connect the core 1021 and the outer ring structure 1022. The receiving circuit board 133 is arranged on a side of the support arm 1023 away from the clothing processing chamber 10a.

[0155] It can be understood that the core 1021 is roughly arranged in the central area of ​​the back cover 102, and the multiple support arms 1023 are radially distributed along the circumference of the core 1021, which means that the multiple 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.

[0156] 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.

[0157] 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.

[0158] The receiving circuit board 133 is arranged on a side of the support arm 1023 away from the clothing processing chamber 10a, that is, the receiving circuit board 133 can be against the support arm 1023, and the support arm 1023 provides installation support for the receiving circuit board 133, thereby increasing the installation stability of the receiving circuit board 133. In addition, the probability of the receiving circuit board 133 contacting the clothing can be reduced, which facilitates the connection between the receiving circuit board 133 and the receiving coil 131.

[0159] In some embodiments, the laundry processing device 1 includes a second bracket 132 , and the receiving coil 131 and the receiving circuit board 133 are integrated on the second bracket 132 .

[0160] In this embodiment, the receiving coil 131 and the receiving circuit board 133 are integrated by the second bracket 132, and the receiving coil 131 and the receiving circuit board 133 do not need to be connected 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 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 convenience of each component is high. The second 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.

[0161] The specific structure of the second bracket 132 is not limited.

[0162] For some examples, see Figure 7 The second 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.

[0163] 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 .

[0164] 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.

[0165] It is understandable that in the embodiment where the receiving coil 131 and the receiving circuit board 133 are spaced apart from each other, see Figure 8 The receiving coil 131 can also be supported on a second bracket 132 and connected to the clothing processing drum 10 through the second bracket 132.

[0166] For some examples, see Figure 7 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 .

[0167] 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.

[0168] The specific structure of the annular portion 1321 is not limited.

[0169] 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.

[0170] 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.

[0171] 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 .

[0172] That is, one end of the connecting portion 1322 can 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 is connected to the rear cover 102 to achieve the connection between the second 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.

[0173] 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 second 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.

[0174] 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.

[0175] For some examples, see Fig.15 The receiving coil 131 is arranged on the circumferential outer side of the clothing processing drum 10 , and the transmitting coil 121 is arranged on the inner side of the box body 11 .

[0176] In this embodiment, the receiving coil 131 is arranged on the circumferential outer side of the laundry treatment drum 10, that is, the axis of the receiving coil 131 is arranged along the radial direction of the laundry treatment drum 10. During the rotation of the laundry treatment drum 10, the transmitting coil 121 is stationary relative to the laundry treatment drum 10. When the receiving coil 131 rotates with the laundry treatment drum 10 to a set area, the receiving coil 131 is opposite to the transmitting coil 121 in the set area, so that the receiving coil 131 receives the electromagnetic signal emitted by the transmitting coil 121 and generates an induced current to provide electrical energy for the electrical components. Outside the set area, the receiving coil 131 and the transmitting coil 121 cannot transmit electrical energy.

[0177] In this embodiment, the receiving coil 131 transmits power to the transmitting coil 121 by rotating with the laundry treatment drum 10, thereby supplying power to the electrical components. There is sufficient space for the receiving coil 131 to be arranged on the circumferential outer side of the laundry treatment drum 10 and the transmitting coil 121 to be arranged on the inner side of the housing 11, and the requirements for the installation positions of the receiving coil 131 and the transmitting coil 121 can be reduced, as long as they can be relative to each other through rotation.

[0178] For example, see Fig.15 The housing 11 includes a top plate 112 , a transmitting coil 121 is disposed on a side of the top plate 112 facing the laundry processing drum 10 , and a receiving coil 131 is disposed on the circumferential outer side of the laundry processing drum 10 .

[0179] In some other embodiments, please refer to Fig.13 The receiving coil 131 is arranged on the circumferential outer side of the clothing processing drum 10. The clothing processing device 1 includes a base 16, which is arranged at the bottom of the box body 11. The base 16 has a drying channel, which is connected to the clothing processing chamber 10a. The transmitting coil 121 is arranged on the side of the base 16 facing the clothing processing drum 10.

[0180] Specifically, the airflow after heat and moisture exchange with the clothes can enter the drying channel, complete condensation dehumidification and heating in the drying channel, and form a new dry hot airflow to enter the clothing processing chamber 10a to dry the clothes. 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 outlet, the air supply channel, the air supply outlet and the air inlet in sequence.

[0181] 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.

[0182] In this embodiment, the receiving coil 131 is arranged on the circumferential outer side of the clothing treatment drum 10, that is, the axis of the receiving coil 131 is arranged along the radial direction of the clothing treatment drum 10, and the transmitting coil 121 is arranged on the side of the base 16 facing the clothing treatment drum 10. During the rotation of the clothing treatment drum 10, the transmitting coil 121 is stationary relative to the clothing treatment drum 10. When the receiving coil 131 rotates with the clothing treatment drum 10 to a set area, the receiving coil 131 is opposite to the transmitting coil 121 in the set area, so that the receiving coil 131 receives the electromagnetic signal emitted by the transmitting coil 121 and generates an induced current to provide electrical energy for the electrical components. Outside the set area, the receiving coil 131 and the transmitting coil 121 cannot achieve power transmission.

[0183] In this embodiment, the receiving coil 131 transmits power to the transmitting coil 121 by rotating with the laundry treatment drum 10, thereby supplying power to the electrical components.

[0201] In some embodiments, the laundry processing device 1 includes a detection unit 15 , which is used to detect the conductivity of the laundry in the laundry processing chamber 10 a . The detection unit 15 is electrically connected to the receiving module 13 .

[0202] It can be understood that the detection unit 15 is one of the above-mentioned electrical components.

[0203] 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.

[0204] 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.

[0205] The installation position of the detection unit 15 in the laundry processing tub 10 is not limited.

[0206] 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 .

[0207] Specifically, the detection electrode 151 is arranged on the outer surface of the lifting rib 14 to facilitate 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 while providing an installation space for the detection circuit, thereby reducing the probability of the detection circuit contacting the clothes to a certain extent and increasing the installation and working reliability of the detection unit 15.

[0208] 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.

[0209] 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.

[0210] The specific structure of the detection electrode 151 is not limited.

[0211] For example, see Figures 19 to 22 , 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.

[0212] 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.

[0213] 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.

[0214] For some examples, see Fig. 20 , 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.

[0215] 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.

[0216] In this embodiment, the first electrode member and the second electrode member have simple and compact structures and neat and beautiful appearances.

[0217] For some examples, see Fig.21 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.

[0218] 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.

[0219] For some examples, see Fig.19 and Fig. 20 , 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.

[0220] For some examples, see Fig.19 and Fig. 20, 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.

[0221] 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.

[0222] 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.

[0223] For some examples, see Fig.21 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.

[0224] 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 .

[0225] 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.

[0226] 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.

[0227] In some embodiments, the first electrode member and the first terminal 1515 may be an integrally formed structure.

[0228] 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.

[0229] In some embodiments, the second electrode member and the second terminal 1516 may be an integrally formed structure.

[0230] The specific structure of the lifting rib 14 is not limited. For some examples, please refer to Fig.17 and Fig.18 The lifting rib 14 includes a main body 141 and an extension 142. The main body 141 is arranged on the circumferential surface of the clothing processing chamber 10a. The extension 142 is connected to the rear end of the main body 141 and is arranged on the rear surface of the clothing processing chamber 10a. The space in the main body 141 and the space in the extension 142 define a connecting passage 14a. Without increasing the radial dimension of the lifting rib 14, the extension 142 is arranged on the rear surface of the clothing processing chamber 10a to increase the volume of the connecting passage 14a, so as to accommodate the receiving circuit board 133, the detection circuit of the detection unit 15, etc.; the extension 142 can cover a part of the rear surface of the clothing processing chamber 10a, so as to shield the hole for passing the wire arranged on the rear side wall of the clothing processing drum 10.

[0231] For some examples, see Fig.18 The extension portion 142 has an opening 142a toward the rear side, and the rear surface of the laundry processing chamber 10a can shield the opening 142a of the extension portion 142 toward the rear side.

[0232] In some examples, 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.

[0233] In some examples, the rearward surface of the extension 142 fits the rear surface of the laundry processing chamber 10a, so that the gap between the extension 142 and the rear surface of the laundry processing chamber 10a can be reduced, and the hair scraps in the laundry processing chamber 10a are prevented from entering the communication channel 14a through the gap.

[0234] 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.

[0235] 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.

[0236] 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.

[0237] Exemplarily, both the evaporator and the condenser may be fin-tube heat exchangers.

[0238] Exemplarily, the throttling device includes but is not limited to an electronic expansion valve and the like.

[0239] 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.
