In addition, the ordinal numbers "first", "second" and the like are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0032] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] As pointed out in the background technology, due to the rotation of the drying drum, in order to reduce the difficulty of arrangement, the dryness sensor in the prior art is installed on the front bracket away from the door seal of the clothes, and cannot come into close contact with the clothes, resulting in the problem that the dryness degree of the clothes cannot be accurately detected. The present invention provides a clothing processing device, which aims to achieve close contact with the clothes and accurately detect the dryness degree of the clothes by arranging the dryness sensor in the drying drum.

[0034] The clothing processing device of the present invention may be a washing machine, a washer-dryer, a clothes dryer, a drying machine, or the like that can dry clothing, and no specific limitation is made herein.

[0035] See first Figure 1 , which shows the cross-sectional structure of the clothing processing device of the present invention. The clothing processing device includes a drying drum 1, a dryness sensor, a signal transmitting module, and a power supply component. A rotating shaft is provided on the drying drum 1. The output shaft of the motor is connected to the rotating shaft and drives the drying drum 1 to rotate by driving the rotating shaft. Clothes to be dried are placed in the drying drum 1, and the clothes are dried while the drying drum 1 rotates; the dryness sensor is provided in the drying drum 1, and the dryness sensor is used to detect the dryness of the clothes. The dryness sensor is directly provided in the drying drum 1 and can contact the clothes at a close distance, so as to achieve the purpose of more accurately detecting the dryness of the clothes, especially when a large amount of clothes needs to be dried or the clothes are far apart. The signal transmitting module is configured to rotate with the drying drum 1 and is connected to the dryness sensor for communication. The signal transmitting module is used to transmit the detection result of the dryness sensor. After receiving the detection result, the controller controls the operation of related programs according to the detection result; The power supply component includes an electromagnetic wave transmitter 2 and an electromagnetic wave receiving device 3. The electromagnetic wave transmitter 2 is installed on the shell of the clothing processing equipment, and the electromagnetic wave receiving device 3 is installed on the drying drum 1. The electromagnetic wave receiving device 3 is connected to the signal transmitting module and the dryness sensor respectively. The power supply component is used to provide electric energy for the dryness sensor and the signal transmitting module to ensure the normal operation of the dryness sensor and the signal transmitting module. Since the electromagnetic wave receiving device 3 can receive the electromagnetic waves emitted by the electromagnetic wave transmitter 2 and convert them into electric energy to power the dryness sensor and the signal transmitting module, the electromagnetic wave receiving device 3 is fixedly set with the drying drum 1, thereby avoiding the line being broken due to the dryness sensor being set in the drying drum 1 and rotating with the drying drum 1, thereby improving the safety of use, ensuring the normal operation of the dryness sensor and the signal transmitting module, and then achieving the purpose of accurately detecting the dryness degree of clothing.

[0036] It should be noted that the electromagnetic wave receiving device 3 can be a wireless sensor node or an electromagnetic wave receiver, as long as it can receive the electromagnetic waves emitted by the electromagnetic wave transmitter 2 and convert them into electrical energy; in addition, although the above combination Figure 1 It is described that the electromagnetic wave transmitter 2 is installed on the shell of the clothing processing device, but this is not restrictive. On clothing processing devices provided with an outer drum, such as washing machines, washer-dryers, etc., the electromagnetic wave transmitter 2 can also be installed on the outer drum, as long as it does not rotate with the drying drum 1. These adjustments do not deviate from the principles of the present invention and are within the protection scope of the present invention.

[0037] Specifically, the dryness sensor includes a sensing element 4 and a dryness chip connected to the sensing element 4. The dryness chip is communicatively connected to the signal transmitting module. The sensing element 4 is used to sense the moisture change information in the drying drum 1. The dryness chip is used to process the information sensed by the sensing element 4 and convert it into the dryness of the clothes, and then transmit the detection result through the signal transmitting module. The sensing element 4 is installed on the outer wall of the lifting rib 6 in the drying drum 1, the dryness determination chip is arranged inside the lifting rib 6, and the electromagnetic wave receiving device 3 and the signal transmitting module are also arranged inside the lifting rib 6; since the lifting rib 6 rotates with the drying drum 1, and the lifting rib 6 contacts the clothes more frequently and closely, the sensing element 4 is arranged on the lifting rib 6, which helps to improve the accuracy of the sensing element 4 in detecting the dryness of the clothes; at the same time, the lifting rib 6 also provides protection for the dryness determination chip and the electromagnetic wave receiving device 3, and achieves the purpose of waterproofing, dustproofing and bump-proofing; in addition, the electromagnetic wave receiving device 3, the dryness determination chip and the signal transmitting module are jointly arranged inside the lifting rib 6, so that the distance between the electromagnetic wave receiving device 3 and the dryness determination chip and the signal transmitting module is relatively close, which facilitates the line arrangement between the electromagnetic wave receiving device 3 and the dryness determination chip and the signal transmitting module.

[0038] Possibly, the dryness determination chip and the sensing element 4 are connected via a signal line, and the signal line is arranged through the lifting rib 6. A sealing structure such as a sealing ring, a sealant, etc. is arranged between the signal line and the lifting rib 6. A sealing structure such as a sealing gasket, a sealant, etc. is also arranged between the lifting rib 6 and the drying cylinder 1, which is used to ensure the sealing of the space inside the lifting rib 6 and prevent the water in the drying cylinder 1 from entering the lifting rib 6, thereby ensuring the normal use of the dryness determination chip, the electromagnetic wave receiving device 3, the signal transmitting module and other devices in the lifting rib 6.

[0039] Optionally, the sensing element 4 is a metal sheet, which can form an electrostatic field with the drying drum 1 and sense the change of the electrostatic field, thereby achieving the purpose of detecting the humidity in the drying drum 1; a socket is provided on the lifting rib 6, and the end of the metal sheet is bent and plugged and fixed with the socket, which is convenient for the disassembly, maintenance and replacement of the sensing element 4. It should be noted that the bending structure of the metal sheet can be provided with multiple, and the corresponding socket is also provided with a number corresponding to the bending structure, for achieving a more secure installation. In addition, in addition to being plugged and fixed on the outer wall of the lifting rib 6, the sensing element 4 can also be fixed on the outer wall of the lifting rib 6 by integral injection molding, or can be installed on the outer wall of the lifting rib 6 by bolt installation or bonding installation. Those skilled in the art can make adjustments as needed, and these adjustments do not deviate from the principles of the present invention and are within the scope of protection of the present invention. Accordingly, the lifting rib 6 can be an insulating material such as plastic, or a non-insulating material. If the lifting rib 6 is a non-insulating material, an insulating layer needs to be provided between the metal sheet and the lifting rib 6 to ensure that the metal sheet can accurately sense the change of the electrostatic field between the drying drum 1.

[0040] As a possible implementation, the dryness sensor is a 3D perspective drying sensor, which can emit countless electric field lines to the wall of the drying drum 1, forming a bipolar 3D detection field, dynamically scanning the clothes, and the changes in the moisture content of the clothes will affect the changes in the electrostatic field distribution. The sensor can sense these changes and judge the moisture content of the clothes, that is, the degree of drying, through an intelligent algorithm. In addition, the dryness sensor can be a capacitive sensor or a resistive sensor, and can also be a humidity sensor. As long as it can detect the humidity in the drying drum 1, it is within the protection scope of the present invention.

[0041] Continue reading Figure 1 The power supply component also includes a power storage module, which is arranged inside the lifting rib 6. The power storage module is electrically connected to the electromagnetic wave receiving device 3, the dryness determination sensor, and the signal transmitting module respectively. The power storage module is used to store the electric energy obtained by the electromagnetic wave receiving device 3 receiving the electromagnetic wave and then converting it, and serves as a backup power supply to provide electric energy for the dryness determination sensor, signal transmitting module and other electrical devices in the drying drum 1. When the electromagnetic wave transmitter 2 and / or the electromagnetic wave receiving device 3 fails or other situations occur where electric energy cannot be generated normally, the power storage module can also continue to provide a certain amount of electric energy for the dryness determination sensor, signal transmitting module and other electrical devices in the drying drum 1.

[0042] The clothing processing device also includes a circuit board 5, which is arranged inside the lifting rib 6. The dryness determination chip, the signal transmission module and the power storage module are all integrated on the circuit board 5, which facilitates the electrical connection and communication connection of the dryness determination chip, the signal transmission module and the power storage module, optimizes the layout and saves space. It can be understood by those skilled in the art that the dryness determination sensor can also include a separate sensor circuit board, the dryness determination chip is arranged on the sensor circuit board, and the sensor circuit board is electrically and communicatively connected to the circuit board 5.

[0043] It will be understood by those skilled in the art that although the above Figure 1 It is described that the dryness determination chip, signal transmission module, electromagnetic wave receiving device 3, power storage module, and circuit board 5 are all arranged inside the lifting rib 6, but this is not restrictive. Those skilled in the art can also directly arrange the dryness determination chip, signal transmission module, electromagnetic wave receiving device 3, power storage module, and circuit board 5 inside or outside the drying drum 1 as needed, as long as they can rotate with the drying drum 1, and provide a protective shell for the dryness determination chip, signal transmission module, electromagnetic wave receiving device 3, power storage module, and circuit board 5 respectively, as long as they can play a protective role. In addition, although the above combination Figure 1 It is described that the sensing element 4 is arranged on the outer wall of the lifting rib, which is not restrictive. Those skilled in the art can also directly install the sensing element 4 on the inner wall of the drying drum 1 as needed, and arrange an insulating plate between the sensing element 4 and the inner wall of the drying drum 1. These adjustments do not deviate from the principles of the present invention and are within the protection scope of the present invention.

[0044] Continue reading Figure 1 The clothing processing device further includes a signal receiving module 7, which is disposed on the housing of the clothing processing device. The signal transmitting module is in communication connection with the signal receiving module 7. The signal receiving module 7 is used to receive the detection information sent by the signal transmitting module and transmit it to the controller. The controller controls the clothing processing device to make a corresponding response and / or send a reminder message to the user according to the detection result of the dryness sensor. Preferably, the signal receiving module 7 is disposed at the front upper part of the housing of the clothing processing device, close to the controller, so as to facilitate the electrical connection and communication connection between the signal receiving module 7 and the controller. The signal receiving module 7 can also be disposed at other positions on the housing.

[0045] It will be appreciated by those skilled in the art that although the above Figure 1 It is described that the clothing processing device also includes a signal receiving module 7, but this is not restrictive. The clothing processing device may also not be provided with the signal receiving module 7. The signal transmitting module sends the detection result to the cloud server, and the cloud server then sends the detection result to the clothing processing device.

[0046] Preferably, the signal transmitting module is a Bluetooth module or a radio frequency module, and the detection result of the dry sensor is transmitted through the Bluetooth module or the radio frequency module, without the need to be connected through a signal line, thus avoiding the problem of line layout. Possibly, the communication mode of the signal transmitting module and the signal receiving module 7 can also be any one of Mesh, ZigBee, Thread, Z-Wave, NFC, Hilink, UWB, and LiFi. As long as the signal can be transmitted from the signal transmitting module to the signal receiving module 7 through wireless communication, it does not deviate from the principle of the present invention and is within the protection scope of the present invention.

[0047] Continue reading Figure 1 The clothing processing device also includes a dynamic sealing structure, and the signal receiving module 7 and the controller are both arranged within the coverage range of the dynamic sealing structure to prevent water or water vapor in the drying drum 1 from contacting the signal receiving module 7 and the controller and affecting their normal use; optionally, the dynamic sealing structure includes a first dynamic sealing ring 8 and a second dynamic sealing ring 9, the first dynamic sealing ring 8 is an annular member connected to the outer side of the rear wall of the drying drum 1, and the first dynamic sealing ring 8 is slidably connected to the rear shell of the clothing processing device, and the second dynamic sealing ring 9 is an annular member connected to the outer side of the front wall of the drying drum 1, and the second dynamic sealing ring 9 is slidably connected to the front shell of the clothing processing device.

[0048] Regarding the electromagnetic wave transmitter 2 and the electromagnetic wave receiving device 3, since the electromagnetic waves emitted by the electromagnetic wave transmitter 2 are distributed throughout the interior of the clothing processing equipment, especially the interior of the drying drum 1, and then received by the electromagnetic wave receiving device 3 arranged in the drying drum 1, the installation position of the electromagnetic wave transmitter 2 and the electromagnetic wave receiving device 3 is relatively free, and does not require a large space. As long as the electromagnetic wave transmitter 2 is fixed and the wireless sensor is rotated with the drying drum 1, it can be applied to clothing processing equipment of different structures and has a wide range of applications. In addition, electric energy is provided by the electromagnetic wave transmitter 2 and the electromagnetic wave receiving device 3. Since wireless transmission is adopted, no contact is required, so wear between parts can be avoided, the service life is increased, and the cost is reduced.

[0049] Possibly, the electromagnetic waves emitted by the electromagnetic wave transmitter 2 are preferably electromagnetic waves in the Wi-Fi frequency band, which have strong penetrating ability and stability, so that the electromagnetic wave receiving device 3 can continuously and stably receive the electromagnetic wave signal at any position in the drying drum 1; the electromagnetic wave receiving device 3 includes a small electric antenna. Optionally, the small electric antenna adopts a metamaterial of subwavelength size, so that the structure of the small electric antenna is compact, and at the same time, it can stably and efficiently receive the electromagnetic waves emitted by the electromagnetic wave transmitter 2; the electromagnetic wave signal received by the small electric antenna is converted into electrical energy to generate current through a double-layer open ring resonator, and the coupling strength between the double-layer open ring resonators is adjustable, so that the impedance of the small electric antenna is greatly adjustable, thereby achieving the purpose of flexible and efficient impedance matching and continuously and stably generating current.

[0050] It should be noted that the above-mentioned embodiments are only used to illustrate the principles of the present invention and are not intended to limit the scope of protection of the present invention. Without departing from the principles of the present invention, those skilled in the art can adjust the above-mentioned embodiments so that the present invention can be applied to more specific application scenarios.

[0051] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
