[0039] This application provides a garment processing device. Please refer to... Figure 1 The garment processing equipment includes a housing 10 and a garment processing drum 20.

[0040] The housing 10 includes a rear plate 11, and a clothes handling drum 20 is rotatably disposed within the housing 10. The rear plate 11 is located behind the clothes handling drum 20. The clothes handling drum 20 has a clothes handling chamber, and the clothes handling drum 20 drives the clothes inside the clothes handling chamber to rotate. Taking a tumble dryer as an example, the rotation axis of the clothes handling drum 20 is horizontal, and the front side of the clothes handling drum 20 has a clothes inlet, through which the user puts or takes out clothes. During the rotation of the clothes handling drum 20, it drives the clothes from bottom to top. Under the action of gravity, the clothes fall from top to bottom. In this way, the clothes are dispersed, shaken, and their posture is changed under the combined action of the clothes handling drum 20 and gravity.

[0041] Understandably, the housing 10 is an external component of the garment processing equipment, which can protect the internal garment processing drum 20.

[0042] It should be noted that the rear panel 11 refers to the component of the housing 10 located on the rear side of the garment processing equipment along the front-to-back direction. The rear side is the side of the garment processing equipment that is furthest from the user after installation.

[0043] In some embodiments, please refer to Figure 2 and Figure 3 The garment processing device includes a bearing 31 and a support shaft 40. The bearing 31 is mounted on the rear plate 11, and the support shaft 40 connects the garment processing cylinder 20 and the bearing 31. Thus, the rotation of the garment processing cylinder 20 drives the support shaft 40 to rotate. The support shaft 40 is supported on the rear plate 11 via the bearing 31. The bearing 31 provides support for the support shaft 40, helping to improve the stability of the support shaft 40 during rotation, thereby improving the working stability of the garment processing cylinder 20.

[0044] In some embodiments, the garment processing device includes a motor and a conveyor belt. The conveyor belt is wound around the outer peripheral surface of the garment processing drum 20. The motor drives the conveyor belt to move, and the conveyor belt drives the garment processing drum 20 to rotate.

[0045] It should be noted that the bearing 31 only needs to provide rolling support for the support shaft 40, and can be, for example, a deep groove ball bearing, an angular contact ball bearing, a cylindrical roller bearing, a tapered roller bearing, etc.

[0046] In some embodiments, the garment processing device includes a transmitting module and a receiving module. The transmitting module includes a transmitting coil 51 that surrounds the outer periphery of the bearing 31 and is used to transmit electromagnetic signals. The receiving module includes a receiving coil 61 that is disposed in the garment processing cylinder 20 and is used to receive the electromagnetic signals transmitted by the transmitting coil 51 and generate an induced current.

[0047] In this embodiment, the transmitting coil 51 surrounds the outer periphery of the bearing 31, which facilitates the coaxial arrangement of the transmitting coil 51 and the receiving coil 61 along the axial direction of the support shaft 40. The coaxial arrangement helps to align the magnetic fields between the transmitting coil 51 and the receiving coil 61, enhances the magnetic field coupling effect, and helps to improve the power transmission efficiency.

[0048] Furthermore, the bearing 31 is located on the rear plate 11, which facilitates the adjustment of the distance between the transmitting coil 51 and the garment handling cylinder 20 along the axial direction of the support shaft 40, thereby helping to adjust the distance between the transmitting coil 51 and the receiving coil 61. In addition, the transmitting coil 51 surrounds the outer periphery of the bearing 31, which can make full use of the space around the bearing 31 and help to make the garment handling equipment structure compact.

[0049] The receiving coil 61 is located in the clothing processing drum 20, meaning that the receiving coil 61 can rotate with the clothing processing drum 20. The electrical components located in the clothing processing drum 20 can be connected to the receiving coil 61 in a circuit to meet the power requirements.

[0050] The transmitting coil 51 is used to transmit electromagnetic signals, and the receiving coil 61 receives the electromagnetic signals transmitted by the transmitting coil 51 and generates an induced current. That is, the transmitting coil 51 and the receiving coil 61 are wirelessly connected through electromagnetic induction to transmit electrical energy and / or electrical signals, thereby providing electrical energy to the electrical components located in the clothing processing drum 20.

[0051] It should be noted that an electrical component can be a structural element capable of performing an electrical function and / or used in a circuit to perform at least one electrical function. The number of electrical components can be one, two, three, or more.

[0052] Electrical components may include units for detecting the condition of clothing and other units that can improve drying performance, such as units for sterilization.

[0053] By using the garment processing device provided in this application embodiment, the transmitting module and the receiving module wirelessly transmit electrical energy and / or electrical signals. The receiving coil 61 can power electrical components, and the transmitting coil 51 is arranged around the outer periphery of the bearing 31, which facilitates the coaxial arrangement of the transmitting coil 51 and the receiving coil 61 along the axial direction of the support shaft 40. This facilitates the adjustment of the distance between the transmitting coil 51 and the garment processing cylinder 20 along the axial direction of the support shaft 40, thereby helping to adjust the distance between the transmitting coil 51 and the receiving coil 61. In addition, it can make full use of the space around the bearing 31, which helps to make the garment processing device structure compact.

[0054] It is understood that the type of clothing processing equipment is not limited, and can include dryers, washer-dryer combos, etc., and is not restricted here. For example, this application embodiment uses a dryer as an example for illustration.

[0055] For example, such as Figure 1 As shown, the garment processing drum 20 is generally hollow and cylindrical. The garment processing drum 20 can be made of metal, such as stainless steel, etc., and there are no restrictions on its use.

[0056] In some embodiments, please refer to Figure 3 At least a portion of the back plate 11 protrudes along the axial direction of the bearing 31 toward the direction close to the garment processing cylinder 20 or toward the direction away from the garment processing cylinder 20 to form a protruding structure 111. The bearing 31 and the support shaft 40 are both located on the protruding structure 111, and the transmitting coil 51 is located on one side of the protruding structure 111.

[0057] In this embodiment, by protruding the back plate 11 towards or away from the garment processing drum 20, the geometry of the back plate 11 is altered, which helps to increase the effective thickness and distribution of the material, and thus improves the structural strength and rigidity of the back plate 11. The bearing 31 and support shaft 40 are located on the protruding structure 111, which also helps to increase the installation stability of the bearing 31 and support shaft 40. The transmitting coil 51 is located around the outer periphery of the bearing 31 on one side of the protruding structure 111, which also helps to increase the installation stability of the transmitting coil 51.

[0058] It is understood that at least a portion of the back plate 11 may protrude either toward the direction of proximity to the garment handling drum 20 or toward the direction of distance from the garment handling drum 22.

[0059] It is understood that in this embodiment, the transmitting coil 51 is located on one side of the protruding structure 111, meaning that the transmitting coil 51 can be located either on the side of the protruding structure 111 closer to the clothes handling drum 20 or on the side of the protruding structure 111 farther away from the clothes handling drum 20.

[0060] In some embodiments, please refer to Figure 3 The garment processing equipment includes a bearing housing 32, and the bearing 31 is at least partially disposed within the bearing housing 32. That is, the bearing housing 32 can provide installation support for the bearing 31, so that the outer ring of the bearing 31 remains stable, thereby improving the working stability of the bearing 31.

[0061] For example, please continue reading Figure 3 The transmitting coil 51 is sleeved on the outer periphery of the bearing housing 32. That is, the bearing housing 32 can provide a relatively stable mounting position for the transmitting coil 51, further improving the installation stability of the transmitting coil 51.

[0062] In some embodiments, at least a portion of the back plate 11 protrudes axially toward the direction of the bearing 31 toward the garment handling drum 20 to form a protruding structure 111, the protruding structure 111 having a through hole through which the bearing seat 32 passes, such as Figure 3 As shown, at least a portion of the bearing housing 32 protrudes from the surface of the protrusion structure 111 toward the side facing the garment processing tube 20 and forms a protrusion 321, and the transmitting coil 51 extends along the outer periphery of the protrusion 321.

[0063] In this embodiment, the transmitting coil 51 extends along the outer periphery of the protrusion 321, which can make full use of the space around the protrusion 321 and help to make the structure of the garment processing device compact. The protrusion 321 helps to increase the axial dimension of the bearing seat 32 to facilitate the installation of the bearing 31. Moreover, the protruding structure 111 and the protrusion 321 protrude toward the garment processing cylinder 20, which facilitates full utilization of the gap between the back plate 11 and the garment processing cylinder 20. Furthermore, the transmitting coil 51 is located on the outer periphery of the bearing seat 32, that is, on the side of the protrusion 111 closer to the garment processing cylinder 20, which allows the transmitting coil 51 to be positioned close to the garment processing cylinder 20 and close to the receiving coil 61, thus helping to reduce the distance between the transmitting coil 51 and the receiving coil 61.

[0064] In some embodiments, please refer to Figure 3 The edge 322 of the bearing seat 32 on the side away from the clothing processing cylinder 20 is provided on the side of the back plate 11 away from the clothing processing cylinder 20 and extends along the outer periphery of the protrusion 321 to increase the contact area between the edge 322 of the bearing seat 32 and the back plate 11, so as to facilitate a better connection between the bearing seat 32 and the back plate 11.

[0065] For example, bolts, screws, etc. can be used to connect the outer edge of the bearing housing 32 to the rear plate 11.

[0066] In some embodiments, please refer to Figure 3 and Figure 6 The transmitting module includes a first mounting plate 52, which has a first annular opening groove 521. The opening of the first annular opening groove 521 faces the clothing handling tube 20, and the transmitting coil 51 is disposed in the first annular opening groove 521. The first mounting plate 52 provides mounting support for the transmitting coil 51, thereby increasing the installation stability of the transmitting coil 51, and also provides a certain degree of protection for the transmitting coil 51. Moreover, the opening of the first annular opening groove 521 facing the clothing handling tube 20 facilitates the orientation of the transmitting coil 51 toward the receiving coil 61, thereby achieving effective signal transmission.

[0067] For example, the first mounting plate 52 is fitted around the outer periphery of the protrusion 321. As a result, the transmitting coil 51 is fitted around the outer periphery of the protrusion 321.

[0068] In some embodiments, please refer to Figure 3 and Figure 7The receiving module includes a second mounting plate 62, which has a second annular opening groove 621. The opening of the second annular opening groove 621 faces the rear plate 11, and the receiving coil 61 is disposed in the second annular opening groove 621. The second mounting plate 62 provides mounting support for the receiving coil 61, thereby increasing the installation stability of the receiving coil 61, and also provides a certain degree of protection for the receiving coil 61. Moreover, the opening of the second annular opening groove 621 facing the rear plate 11 facilitates the orientation of the receiving coil 61 toward the transmitting coil 51, thereby achieving effective signal transmission.

[0069] For example, such as Figure 3 As shown, the second mounting plate 62 surrounds the outer periphery of the support shaft 40 and is fixed to the garment handling tube 20. This helps to ensure that the receiving coil 61 and the transmitting coil 51 are coaxially arranged.

[0070] In some embodiments, please refer to Figure 3 and Figure 4 The transmitting coil 51 is located on the side of the rear plate 11 facing the clothes handling drum 20, and the transmitting coil 51 and the receiving coil 61 face each other. Positioning the transmitting coil 51 on the front side of the rear plate 11 reduces the distance between the transmitting coil 51 and the receiving coil 61, thereby improving signal transmission efficiency. Furthermore, the facing of the transmitting coil 51 and the receiving coil 61 optimizes magnetic field coupling. The magnetic field lines form a closed loop between the two coils, enhancing the efficiency of electrical energy transmission.

[0071] In some embodiments, such as Figure 1 and Figure 5 As shown, the garment processing tube 20 includes a tube body 21 and a rear cover 22. The rear cover 22 is located at the rear end of the tube body 21, and the receiving coil 61 is located on the side of the rear cover 22 away from the tube body 21. That is, the rear cover 22 is positioned opposite to the rear plate 11, and the receiving coil 61 is located on the side of the rear cover 22 away from the tube body 21, so that the receiving coil 61 can be positioned towards the transmitting coil 51 to achieve effective signal transmission.

[0072] For example, please refer to Figure 3 The transmitting coil 51 and the receiving coil 61 are arranged along the axial direction of the support shaft 40. During the rotation of the clothing processing drum 20, no matter where the receiving coil 61 rotates with the clothing processing drum 20, the receiving coil 61 and the transmitting coil 51 can always maintain a relative state, which makes it easy for the receiving coil 61 to continuously and stably receive the electrical energy transmitted by the transmitting coil 51, so as to achieve effective and sufficient power supply.

[0073] In some embodiments, the transmitting coil 51, the receiving coil 61, and the clothing handling drum 20 are arranged coaxially. That is, no matter where the clothing handling drum 20 is rotated, the transmitting coil 51 and the receiving coil 61 always remain coaxial and relative to each other.

[0074] The distance between the transmitting coil 51 and the receiving coil 61 is unlimited.

[0075] In some embodiments, the distance between the transmitting coil 51 and the receiving coil 61 is 4 mm 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.

[0076] It should be noted that the distance between the transmitting coil 51 and the receiving coil 61 refers to the distance between the transmitting coil 51 and the receiving coil 61 along their axial direction when they are arranged opposite each other.

[0077] Understandably, if the distance between the transmitting coil 51 and the receiving coil 61 is too large, the induced current generated by the receiving coil 61 will be smaller, and thus the main control board will need to provide more operating power to the transmitting coil 51. If the distance between the transmitting coil 51 and the receiving coil 61 is too small, the distance between the transmitting coil 51 and the clothes handling drum 20 will be smaller, which will increase the probability of interference between the transmitting coil 51 and the clothes handling drum 20 and increase the probability of damage to the transmitting coil 51.

[0078] In this embodiment, the distance between the transmitting coil 51 and the receiving coil 61 is neither too large nor too small, and there is a sufficient safe distance between the transmitting coil 51 and the clothing handling drum 20. While increasing the working safety of the transmitting coil 51, the receiving coil 61 can generate a sufficient induced current to meet the power demand of the electrical components.

[0079] In some embodiments, the distance between the transmitting coil 51 and the receiving coil 61 is 5.5mm to 10mm. For example, 5.5mm, 5.7mm, 6mm, 6.2mm, 6.6mm, 7mm, 7.4mm, 8mm, 8.6mm, 9mm, 9.3mm, 9.8mm, 10mm, etc.

[0080] In this embodiment, the distance between the transmitting coil 51 and the receiving coil 61 is more suitable, the probability of the transmitting coil 51 interfering with the clothing processing drum 20 is small, and the transmitting coil 51 can provide sufficient operating current to the receiving coil 61, thereby increasing the reliability of wireless power transmission of the clothing processing equipment.

[0081] In some embodiments, the rear cover 22 is provided with an air inlet, and the rear plate 11 is provided with an air outlet. The rear plate 11 and the rear cover 22 are sealed together so that the airflow from the air outlet can enter the garment processing drum 20 through the air inlet. That is, the rear plate 11 and the rear cover 22 are sealed together, and the air inlet of the rear cover 22 and the air outlet of the rear plate 11 together define a part of the air supply channel so that the drying airflow can enter the garment processing chamber through the air outlet of the rear plate 11 and the air inlet of the rear cover 22.

[0082] In some embodiments, the garment processing device includes a detection unit, and the receiving module includes a receiving circuit board. The detection unit is electrically connected to the receiving circuit board, and the detection unit is used at least to detect the humidity of the garments in the garment processing chamber.

[0083] The detection unit can at least detect the humidity of the clothes in the clothes processing chamber to determine the degree of drying of the clothes.

[0084] It is understandable that the detection unit is one of the aforementioned electrical components.

[0085] The installation position of the detection unit inside the garment processing drum 20 is not limited.

[0086] In some embodiments, the detection unit is located on the inner wall of the clothing processing drum 20.

[0087] It is understood that the detection unit being located on the inner wall of the clothing processing drum 20 means that the detection unit is located in a part that can directly contact the clothing. For example, it could be the circumferential inner surface of the drum body 21 of the clothing processing drum 20, or it could be the surface of the rear cover 22 of the clothing processing drum 20 on the side away from the rear plate 11 of the housing 10.

[0088] In some embodiments, the garment handling device includes a lifting rib 70 disposed on the inner circumferential surface of the garment cylinder 21, and a detection unit is disposed on the lifting rib 70. The lifting rib 70 can contact the garments inside the garment handling chamber and cause the garments to rotate with the garment handling cylinder 20. For example, the garments move upwards under the action of the lifting rib 70, and then move downwards under the action of gravity and centrifugal force, thus the garments continuously change their posture inside the garment handling chamber. That is, the lifting rib 70 can both move the garments and be used to install the detection unit.

[0089] In some embodiments, the garment processing device includes a conical cap disposed on the side of the rear cover 22 away from the rear plate 11, and a detection unit is disposed on the conical cap. The conical cap can disperse the garments during the rotation of the garment processing drum 20, reducing the likelihood of tangling or knotting, resulting in more even drying and improved drying effect. In other words, the conical cap serves both to disperse the garments and to provide installation space for the detection unit.

[0090] Understandably, the detection unit may or may not come into contact with the clothing.

[0091] For example, in some embodiments, the detection unit includes a non-contact sensor; the non-contact sensor is located inside the lifting rib 70; or, the non-contact sensor is located inside the conical cap. In this case, the detection unit does not come into direct contact with the clothing.

[0092] For example, in some embodiments, the non-contact sensor can be a non-contact capacitive sensor. In this embodiment, the non-contact capacitive sensor does not come into direct contact with the clothing, but indirectly measures the moisture content of the clothing by detecting changes in the electric field within the clothing drying drum 20. When the moisture content of the clothing changes, the dielectric constant of the dielectric material within the drying drum changes, resulting in a change in the electric field distribution. The non-contact capacitive sensor then indirectly measures the moisture content of the clothing by measuring the change in capacitance.

[0093] In other embodiments, the non-contact sensor can be a non-contact resistance sensor. In this embodiment, the non-contact resistance sensor is used to indirectly measure the moisture content of the clothing by detecting the combined resistance change of the air and clothing inside the dryer.

[0094] It is understood that in some other embodiments, non-contact capacitive sensors and / or non-contact resistive sensors may also be disposed on the inner wall of the clothing processing drum 20. In this case, a transparent or translucent insulating material, such as glass or plastic, can be used to cover the outside of the sensor to protect the electrodes of the sensor and to avoid direct contact between the sensor and the clothing as much as possible.

[0095] It is understood that in some other embodiments, the detection unit may include a contact sensor, such as a contact resistance sensor, which determines the moisture content of the clothing by direct contact with the clothing. Different levels of moisture in the clothing and other loads have different resistance values, and the moisture content of the clothing is measured by the change in resistance value.

[0096] In other words, for detection units that do not directly contact the clothing, such as those located inside the lifting rib 70 or the conical cap, non-contact sensors are required. For detection units that can directly contact the clothing, such as those located on the surface of the inner wall of the clothing processing drum 20, either contact or non-contact sensors can be used.

[0097] Understandably, the detection unit can also be used to detect the temperature of clothing, etc.

[0098] In some embodiments, the transmitting module includes a transmitting circuit board electrically connected to the transmitting coil 51, and the transmitting circuit board includes a demodulation circuit; the receiving module includes a receiving circuit board electrically connected to the receiving coil 61, and the receiving circuit board includes a modulation circuit electrically connected to the detection unit. The modulation circuit is used to receive the detection signal from the detection unit and modulate the detection signal into a carrier signal. The receiving coil 61 and the transmitting coil 51 are used to transmit the carrier signal, and the demodulation circuit is used to demodulate the carrier signal into a detection signal. In other words, in addition to transmitting electrical energy, the transmitting and receiving modules can also transmit data signals.

[0099] The clothing-related information detected by the detection unit can be transmitted to the receiving module, which then transmits the information to the transmitting module. Specifically, the modulation circuit receives the detection signal from the detection unit and modulates it into a carrier signal. The receiving coil 61 transmits the carrier signal, and the transmitting coil 51 receives the carrier signal. The carrier signal is then demodulated into a detection signal by the demodulation circuit. In other words, the transmitting coil 51 can generate electromagnetic signals and also receive data signals, while the receiving coil 61 can generate induced current and also transmit data signals.

[0100] It is understood that in this embodiment, power transmission and data transmission integration can be achieved through frequency separation, that is, the frequency of power transmission and the frequency of data transmission have significantly different ranges. For example, the frequency range of power transmission is in the range of tens of kHz to hundreds of kHz, and the frequency range of data transmission is in the range of several MHz to tens of MHz.

[0101] In some embodiments, filters can be used to separate power transmission signals and data transmission signals to reduce mutual interference.

[0102] It is understood that in other embodiments, power transmission and data transmission may not be integrated into a transmitting module and a receiving module. In this case, a data transmitting coil 51 can be set on the clothing processing tube 20, and the modulation circuit can be electrically connected to the data transmitting coil 51. A data receiving coil 61 can be set on the rear plate 11 of the housing 10, and the demodulation circuit can be electrically connected to the data receiving coil 61, thereby realizing the separation of power transmission and data transmission functions.
