Description

[0059] The present application embodiment provides a clothes processing device 1, see Figures 1 to 19 The clothing processing device 1 includes a housing 11 , a clothing processing drum 10 , a main control board, a wireless power supply component and a cable 19 .

[0060] 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.

[0061] The housing 11 includes a rear plate 111 .

[0062] Specifically, the housing 11 is an appearance component of the clothes processing device 1 , and can protect the clothes processing drum 10 inside.

[0063] It should be noted that the rear plate 111 refers to a component of the housing 11 located at the rear side of the laundry processing device 1 along the front-rear direction. The rear side is the side of the laundry processing device 1 that is away from the user after installation.

[0064] The laundry processing drum 10 is disposed in the housing 11. Specifically, the laundry processing drum 10 is rotatably disposed in the housing 11.

[0065] 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.

[0066] 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.

[0067] The embodiment of the present application is described by taking the clothing processing device 1 adopting a single-drum structure as an example.

[0068] 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.

[0069] The main control board is used to control the operation of the laundry processing device 1. Specifically, the main control board can control the operation time, operation mode, etc. of the laundry processing device 1, and provide power to other components.

[0070] 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.

[0071] 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.

[0072] The transmitting module 12 and the receiving module 13 can be wirelessly connected by electromagnetic induction.

[0073] Exemplarily, the transmitting module 12 is disposed on the rear plate 111 .

[0074] It should be noted that the transmitting module 12 is arranged on the rear plate 111. The various components of the transmitting module 12 can be integrated together and arranged on the rear plate 111 as a whole, or the various components of the transmitting module 12 can be dispersedly arranged at different positions on the rear plate 111, and there is no limitation here.

[0075] The transmitting module 12 does not rotate with the rotation of the laundry treatment drum 10, and does not affect the electrical connection between the transmitting module 12 and the main control board. The transmitting module 12 is wirelessly connected to the receiving module 13, that is, the transmitting module 12 can wirelessly transmit power to the receiving module 13, and the receiving module 13 can receive the power transmission from the transmitting module 12 during the rotation of the laundry treatment drum 10.

[0076] The receiving module 13 is not limited to a setting position. For example, the receiving module 13 is set in the laundry processing drum 10, so that the receiving module 13 can be closer to the electrical components in the laundry processing drum 10. That is, during the operation of the laundry processing device 1, when the laundry processing drum 10 rotates, the receiving module 13 also rotates.

[0077] 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.

[0078] The transmitting module 12 includes a transmitting coil 121. Specifically, the transmitting coil 121 is used to transmit electromagnetic signals. Exemplarily, the receiving module 13 may include a receiving coil 131 to receive the electromagnetic signal transmitted by the transmitting coil 121 and generate an induced current.

[0079] Specifically, the transmitting coil 121 generates a changing magnetic field, and the receiving coil 131 generates an induced current through electromagnetic induction to receive the power transmission from the transmitting coil 121 .

[0080] In this way, the electrical components disposed in the laundry processing drum 10 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.

[0081] 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.

[0082] 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.

[0083] See also Figure 1 , the transmitting coil 121 is arranged on the side of the rear plate 111 facing the laundry treatment tub 10. That is, the transmitting coil 121 does not rotate with the laundry treatment tub 10, and the transmitting coil 121 is arranged toward the laundry treatment tub 10. When the receiving module 13 is arranged in the laundry treatment tub 10, the transmitting coil 121 can be arranged close to the receiving module 13, shortening the distance between the receiving module 13 and facilitating the transmission of sufficient electric energy to the receiving module 13, so as to supply sufficient electric energy to the electrical components in the laundry treatment tub 10.

[0084] See also Figure 3 , the transmitting coil 121 and the main control board establish a conductive path through the cable 19. The rear plate 111 has a first wire opening 111a, one end of the cable 19 is connected to the transmitting coil 121, and a part of the cable 19 passes through the first wire opening 111a to the side of the rear plate 111 away from the laundry treatment tub 10.

[0085] Specifically, the first wire-passing opening 111a is used for passing the cable 19, and the first wire-passing opening 111a may be one or more, and is not limited here. The cable 19 passes through the first wire-passing opening 111a from the side of the rear plate 111 close to the laundry treatment drum 10 to the side of the rear plate 111 away from the laundry treatment drum 10, that is, the cable 19 passes through the first wire-passing opening 111a from the front side of the rear plate 111 to the rear side of the rear plate 111, and the rear side of the rear plate 111 has sufficient space to facilitate the arrangement of the cable 19 and increase the safety of the cable 19.

[0086] It should be noted that the transmitting coil 121 and the main control board establish a conductive path through the cable 19. It can be that there is no other intermediate component in the electrical connection between the transmitting coil 121 and the main control board, and the cable 19 directly connects the transmitting coil 121 and the main control board; it can also be that there is an intermediate component in the electrical connection between the transmitting coil 121 and the main control board, for example, other components of the transmitting module 12, and the cable 19 connects the transmitting coil 121, the intermediate component, and the main control board in sequence to form a conductive path; it can also be that the transmitting coil 121 is integrated with other components of the transmitting module 12, and the cable 19 directly connects other components of the transmitting module 12 and the main control board to realize the electrical connection between the transmitting coil 121 and the main control board.

[0087] 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, and have high reliability. The main control board provides electric energy for the transmitting module 12, and the cable 19 is passed through the first wire port 111a on the rear plate 111, and a conductive path is established between the transmitting module 12 and the main control board to meet the power demand of the electrical components in the clothing processing drum 10 and to sense the clothing status at close range and realize specific functions. The cable 19 passes through the first wire port 111a from the front side of the rear plate 111 to the rear side of the rear plate 111, which can increase the layout safety of the cable 19 and reduce the probability of interference between the cable 19 and the rotating clothing processing drum 10. At the same time, the cable 19 has sufficient layout space on the rear side of the rear plate 111, which is convenient for realizing the connection between the cable 19 and the main control board, and improving the working reliability of the clothing processing device 1.

[0088] For example, see Figure 1 The transmitting coil 121 and the receiving coil 131 are roughly ring-shaped structures.

[0089] The arrangement of the transmitting coil 121 and the receiving coil 131 is not limited. For example, the transmitting coil 121 is arranged 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 that, with 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, the receiving coil 131, and the laundry treatment drum 10 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] The distance between the transmitting coil 121 and the receiving coil 131 is not limited.

[0093] 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.

[0094] 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.

[0095] 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.

[0096] 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.

[0097] 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.

[0098] 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.

[0099] For some examples, see Figure 4 The radial edge of the rear end of the laundry processing tub 10 is dynamically sealed with the inner surface of the rear plate 111 , and the transmitting coil 121 is located within the rotation track range of the radial edge of the laundry processing tub 10 .

[0100] It should be noted that the dynamic sealing cooperation means that the radial edge of the rear end of the clothing processing drum 10 is sealed and connected to the inner surface of the rear plate 111, and the clothing processing drum 10 can rotate relative to the rear plate 111. The dynamic sealing cooperation can achieve sealing without affecting the rotation of the clothing processing drum 10, thereby reducing the probability of airflow overflowing from the joint between the rear plate 111 and the clothing processing drum 10.

[0101] It can be understood that the transmitting coil 121 is located within the rotation track range of the radial edge of the laundry treatment drum 10, which means that the projection of the transmitting coil 121 is located within the projection of the laundry treatment drum 10 along the projection perpendicular to the front-to-back direction of the laundry treatment device 1. In the state of dynamic sealing cooperation between the laundry treatment drum 10 and the rear plate 111, if it is necessary to establish a conductive path between the transmitting coil 121 and the main control board, one end of the cable 19 is connected to the transmitting coil 121, and the other end passes through the first wire opening 111a to the rear side of the rear plate 111, so that there is enough layout space on the rear side to achieve electrical connection with the main control board.

[0102] See also Figure 3 The rear plate 111 has a second wire opening 111b, which is located outside the rotation trajectory of the radial edge of the clothing treatment drum 10. A portion of the cable 19 passes through the second wire opening 111b from the rear side of the rear plate 111 and is connected to the main control board in the box body 11.

[0103] That is to say, the main control board is located inside the box body 11. In the dynamic sealing cooperation state, the cable 19 first passes through the first wire passing port 111a to the rear side of the rear plate 111, and then passes through the second wire passing port 111b of the rear plate 111 to the box body 11 to achieve electrical connection with the main control board, thereby realizing a conductive path between the transmitting coil 121 and the main control board.

[0104] In this embodiment, the electrical connection between the transmitting coil 121 and the main control board is achieved by setting the first wire passing port 111a and the second wire passing port 111b. On the one hand, the probability of the cable 19 contacting the rotating clothing treatment drum 10 is reduced, and the layout safety of the cable 19 is increased. The rear plate 111 has enough space for the cable 19 to be arranged. On the other hand, it can also not affect the dynamic sealing cooperation between the clothing treatment drum 10 and the rear plate 111, thereby increasing the working reliability of the clothing treatment device 1.

[0105] In some embodiments, the transmitting module 12 includes a transmitting circuit board 123, which is electrically connected to the transmitting coil 121. The transmitting circuit board 123 is arranged on the side of the rear plate 111 away from the clothing processing drum 10. The cable 19 includes a first sub-segment and a second sub-segment. The first sub-segment connects the transmitting circuit board 123 and the transmitting coil 121, and the second sub-segment connects the transmitting circuit board 123 and the main control board.

[0106] Specifically, the transmitting module 12 can be electrically connected to the main control board of the laundry processing device 1 through the transmitting circuit board 123 .

[0107] The transmitting circuit board 123 includes a power supply circuit, which can realize power transmission to the receiving module 13. For example,

[0108] The transmitting circuit board 123 also includes a modulation and demodulation circuit. The modulation and demodulation circuit can realize signal conversion. That is, the transmitting module 12 can also transmit information.

[0109] In this embodiment, the transmitting circuit board 123 and the transmitting coil 121 are dispersedly arranged, and the transmitting circuit board 123 serves as an intermediate element between the transmitting coil 121 and the main control board. 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 transmitting coil 121 and the transmitting circuit board 123, and the second sub-segment realizes the electrical connection between the transmitting circuit board 123 and the main control board. Exemplarily, one end of the first sub-segment is connected to the transmitting coil 121, and the other end passes through the first wire port 111a to the rear side of the rear plate 111 and is connected to the transmitting circuit board 123. One end of the second sub-segment is connected to the transmitting circuit board 123, and the other end passes through the second wire port 111b to enter the inner side of the box body 11 and is connected to the main control board.

[0110] In this embodiment, the transmitting coil 121 is arranged on the side of the rear plate 111 facing the laundry treatment drum 10, and the transmitting circuit board 123 is arranged on the side of the rear plate 111 away from the laundry treatment drum 10. The cable 19 establishes a conductive path between the transmitting coil 121, the transmitting circuit board 123 and the main control board. On the one hand, the transmitting coil 121 can be arranged as close to the receiving coil 131 as possible, and the transmitting coil 121 transmits sufficient electrical energy to the receiving coil 131. The transmitting circuit board 123 can be arranged as far away from the laundry treatment drum 10 as possible to reduce the influence of air flow and facilitate the establishment of a connection with the main control board. In addition, the transmitting coil 121 and the transmitting circuit board 123 can be arranged in smaller areas respectively to reduce the influence on the overall layout of the laundry treatment device 1.

[0111] For some examples, see Fig.13 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 is formed with 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 emitting circuit board 123 and the first wire opening 111a are arranged at the part of the rear plate 111 not covered by the rear cover 17.

[0112] Exemplarily, the clothing processing drum 10 also has 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.

[0113] For example, see Fig.13 The clothing processing device 1 may further include a base 16, wherein the base 16 has a drying channel, and the air supply channel and the drying channel together form a circulating air channel, wherein the drying channel is located upstream of the air supply channel along the air flow direction in the circulating air channel, and the drying channel is connected to the air outlet, and the air flow after heat and moisture exchange with the clothing can enter the drying channel through the air outlet, complete condensation dehumidification and heating in the drying channel, and form a new dry hot air flow, which then enters the clothing processing chamber 10a through the return air port, the air supply channel, and the air supply port.

[0114] 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.

[0115] It should be noted that the transmitting circuit board 123 and the first wire opening 111a are arranged at a position of the rear plate 111 not covered by the rear cover 17, that is, the transmitting circuit board 123 and the first wire opening 111a are arranged at a position on the rear side of the rear plate 111 outside the rear cover 17.

[0116] In this embodiment, the transmitting circuit board 123 and the first wire opening 111a are arranged at the position of the rear plate 111 not covered by the rear cover 17, which can reduce the impact of airflow on the transmitting circuit board 123. In addition, the cable 19 does not need to pass through the rear cover 17 to connect to the main control board, which increases the simplicity of wiring and the air supply reliability of the air supply channel.

[0117] In some embodiments, the transmitting module 12 includes a transmitting circuit, which is electrically connected to the transmitting coil 121 , wherein the transmitting circuit is integrated on the main control board, and the cable 19 connects the transmitting coil 121 and the output end of the transmitting circuit.

[0118] It can be understood that the transmitting circuit described in this embodiment has the same function as the above-mentioned transmitting circuit board 123. The transmitting circuit of this embodiment is part of the main control board. The transmitting circuit board 123 in the above-mentioned embodiment is a separate module and needs to be installed in the form of a transmitting circuit board 123.

[0119] In this embodiment, the electric energy supplied by the main control board can be obtained by simply connecting the transmitting coil 121 and the output end of the transmitting circuit. The wiring is simple and convenient, and there is no need to arrange additional installation space for the transmitting circuit board 123.

[0120] For some examples, see Figure 5 and Figure 6 The transmitting module 12 includes a first bracket 122 .

[0121] The transmitting coil 121 is spaced apart from the transmitting circuit board 123 , and the transmitting coil 121 is supported on the first bracket 122 .

[0122] That is, the transmitting coil 121 and the transmitting circuit board 123 are dispersedly arranged, the first bracket 122 provides support for the transmitting coil 121 , and the transmitting coil 121 can be connected to the rear plate 111 through the first bracket 122 .

[0123] In this embodiment, the transmitting coil 121 and the transmitting circuit board 123 can be electrically connected through the first subsection of the cable 19, and the second subsection of the cable 19 connects the transmitting circuit board 123 and the main control board.

[0124] 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 it carries, and increase the safety of the transmitting circuit board 123.

[0125] Exemplarily, the length of the first subsection 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. That is, the distance between the transmitting coil 121 and the transmitting circuit board 123 can be more reasonable, reducing the probability of electromagnetic interference and reducing power loss.

[0126] In some other embodiments, the transmitting coil 121 and the transmitting circuit board 123 are integrated on the first bracket 122 .

[0127] 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.

[0128] The specific structure of the first bracket 122 is not limited.

[0129] For some examples, see Figure 5 and Figure 6 The first bracket 122 includes a first annular portion 1221 and a first connecting portion 1222 connected to the first annular portion 1221 . The transmitting coil 121 is disposed on the first annular portion 1221 . The first connecting portion 1222 is connected to the rear plate 111 .

[0130] In this embodiment, the first annular portion 1221 provides an installation space for the transmitting coil 121, and the first connecting portion 1222 is connected to the rear plate 111. The first annular portion 1221 and the first connecting portion 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.

[0131] For some examples, see Figure 6 The first annular portion 1221 is formed with a first annular groove 1221a, the first annular groove 1221a is open toward one side of the rear cover 102, and the transmitting coil 121 is accommodated in the first annular groove 1221a.

[0132] Specifically, the first annular groove 1221a is an annular space defined by the structure of the first annular portion 1221. The first annular groove 1221a is open toward the side of the rear cover 102, 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.

[0133] The specific structure of the first annular portion 1221 is not limited.

[0134] For some examples, see Figure 6 The first annular portion 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.

[0135] Specifically, when the transmitting coil 121 cooperates with the first annular portion 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 docking between the transmitting coil 121 and the first annular portion 1221.

[0136] The first connection portion 1222 is disposed on the radially outer side of the first outer annular wall 12213 , or the first connection portion 1222 is disposed on the radially inner side of the first inner annular wall 12212 .

[0137] That is, one end of the first connection portion 1222 may be connected to the first outer annular wall 12213 or the first inner annular wall 12212, and the other end of the first connection portion 1222 may be connected to the rear plate 111 to achieve the connection between the first bracket 122 and the rear plate 111. For example, see Figure 6 The first connection portion 1222 is disposed on the radially outer side of the first outer annular wall 12213 , so that the first connection portion 1222 can have sufficient extension space to achieve a stable connection with the rear plate 111 .

[0138] In this embodiment, the transmitting coil 121 is conveniently connected to the first annular portion 1221, and the transmitting coil 121 can be easily disassembled and inspected. The first annular portion 1221 has a simple structure, which can reduce the manufacturing requirements for the first bracket 122. The setting position of the first connecting portion 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.

[0139] The first connection portion 1222 may be detachably connected to the rear plate 111 . For example, the first connection portion 1222 may be connected to the rear plate 111 by screws, which is not limited herein.

[0140] For some examples, see Figure 1 The laundry processing drum 10 includes a drum body 101 and a rear cover 102 , and the rear cover 102 is arranged at the rear end of the drum body 101 .

[0141] At least a portion of the receiving module 13 is disposed on a side of the rear cover 102 away from the barrel body 101 .

[0142] It should be noted that the receiving module 13 can be a whole structure arranged on the side of the rear cover 102 away from the barrel 101, or a part of the structure arranged on the side of the rear cover 102 away from the barrel 101, and the other part arranged inside the barrel 101 or arranged on the side of the rear cover 102 facing the barrel 101, and there is no limitation here.

[0143] In this embodiment, the setting of the receiving module 13 can, on the one hand, minimize the probability of contact with the clothes in the clothing processing chamber 10a and reduce the probability of occupying the space in the clothing processing chamber 10a. On the other hand, it can also be arranged as close to the transmitting module 12 as possible to facilitate receiving sufficient power transmission.

[0144] For example, see Figure 7 The receiving coil 131 is arranged on a side of the rear cover 102 away from the barrel body 101 .

[0145] 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.

[0146] The receiving coil 131 is arranged on the side of the rear cover 102 away from the barrel 101. In this way, the receiving coil 131 does not contact the clothes in the clothes processing chamber 10a, reducing the impact 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 barrel 101, which can also facilitate the relative arrangement of the receiving coil 131 and the transmitting coil 121.

[0147] In some embodiments, the receiving module 13 includes a receiving circuit board 133 , and the receiving circuit board 133 is electrically connected to the receiving coil 131 .

[0148] Specifically, the receiving circuit board 133 includes a power output circuit, which can output electrical energy.

[0149] Exemplarily, the receiving circuit board 133 includes a modulation and demodulation circuit, which can realize signal conversion.

[0150] 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.

[0151] 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.

[0152] For some examples, see Figure 1 The laundry processing apparatus 1 comprises lifting ribs 14 which protrude radially from the circumferential inner wall of the laundry processing tub 10 .

[0153] See also Fig.12 The receiving circuit board 133 is disposed in the lifting rib 14 .

[0154] 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.

[0155] 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 .

[0156] 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.

[0157] In some other embodiments, please refer to Fig.11 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 .

[0158] 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.

[0159] For example, the conical cap 18 may be connected to the rear cover 102 at a location approximately in the center.

[0160] 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.

[0161] 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.

[0162] For some examples, see Figures 7 to 9 , the laundry processing apparatus 1 includes a second bracket 132 .

[0163] The receiving coil 131 and the receiving circuit board 133 are integrated on the second bracket 132 .

[0164] 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.

[0165] The specific structure of the second bracket 132 is not limited.

[0166] For some examples, see Figure 8 The second bracket 132 includes a second annular portion 1321, a second connecting portion 1322 and an extending structure 1323. The second connecting portion 1322 and the extending structure 1323 are respectively connected to the second annular portion 1321. The receiving coil 131 is arranged on the second annular portion 1321. The second 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.

[0167] 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 .

[0168] The second annular portion 1321 can be arranged on the side of the core 1021 facing the rear plate 111, that is, the second 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, thereby increasing the movement stability of the receiving coil 131.

[0169] It is understandable that in the embodiment where the receiving coil 131 and the receiving circuit board 133 are spaced apart, refer to the figure, the receiving coil 131 can also be supported on the second bracket 132 and connected to the clothing processing drum 10 through the second bracket 132.

[0170] For some examples, see Figure 8 and Fig. 9 The second 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 .

[0171] Specifically, the second annular groove 1321a is an annular space defined by the structure of the annular portion. 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.

[0172] The specific structure of the annular portion is not limited.

[0173] For some examples, see Figure 8 and Fig. 9 The second 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.

[0174] Specifically, when the receiving coil 131 cooperates with the second 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 second annular portion 1321.

[0175] The second connection portion 1322 is disposed on the radially outer side of the second outer annular wall 13213 , or the second connection portion 1322 is disposed on the radially inner side of the second inner annular wall 13212 .

[0176] That is, one end of the second connection 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 second connection portion 1322 is connected to the rear cover 102 to achieve the connection between the second bracket 132 and the rear cover 102. Figure 8 The second connection portion 1322 is disposed radially inward of the second inner annular wall 13212. In this way, the probability that the second connection portion 1322 affects the air intake of the laundry processing tub 10 at the rear cover 102 can be reduced.

[0177] In this embodiment, the receiving coil 131 is conveniently connected to the second annular portion 1321, and the receiving coil 131 can be easily disassembled and inspected. The second annular portion 1321 has a simple structure, which can reduce the manufacturing requirements for the second bracket 132. The setting position of the second 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.

[0178] The second connection portion 1322 may be detachably connected to the back cover 102 . For example, the second connection portion 1322 may be connected to the back cover 102 by screws, which is not limited herein.

[0188] In some embodiments, the clothing processing device 1 includes a detection unit 15 , which is disposed inside the clothing processing drum 10 and is used to detect the conductivity of clothing in the clothing processing chamber 10 a . The receiving module 13 is electrically connected to the detection unit 15 .

[0189] It can be understood that the detection unit 15 is one of the above-mentioned electrical components.

[0190] 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.

[0191] 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.

[0192] The installation position of the detection unit 15 in the laundry processing tub 10 is not limited.

[0193] For some examples, see Fig.16 The detection unit 15 includes a detection electrode 151 and a detection circuit that are electrically connected to each other. The detection electrode 151 is arranged on the outer surface of the lifting rib 14, the detection circuit is arranged inside the lifting rib 14, and the detection circuit is electrically connected to the receiving module 13.

[0194] 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.

[0195] 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.

[0196] 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.

[0197] The specific structure of the detection electrode 151 is not limited.

[0198] For example, see Figures 16 to 19 , 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.

[0199] 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.

[0200] 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.

[0201] For some examples, see Fig.17 , 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.

[0202] 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.

[0203] In this embodiment, the first electrode member and the second electrode member have simple and compact structures and neat and beautiful appearances.

[0204] For some examples, see Fig.18 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.

[0205] 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.

[0206] For some examples, see Fig.16 and Fig.17, 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.

[0207] For some examples, see Fig.16 and Fig.17 , 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.

[0208] 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.

[0209] 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.

[0210] For some examples, see Fig.18 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.

[0211] 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 .

[0212] 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.

[0213] 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.

[0214] In some embodiments, the first electrode member and the first terminal 1515 may be an integrally formed structure.

[0215] 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.

[0216] In some embodiments, the second electrode member and the second terminal 1516 may be an integrally formed structure.

[0217] The specific structure of the lifting rib 14 is not limited. For some examples, please refer to Fig.14 and Fig.15 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.

[0218] For some examples, see Fig.15 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.

[0219] 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.

[0220] 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.

[0221] 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.

[0222] 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.

[0223] 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.

[0224] Exemplarily, both the evaporator and the condenser may be fin-tube heat exchangers.

[0225] Exemplarily, the throttling device includes but is not limited to an electronic expansion valve and the like.

[0226] 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.
