Technical Field

[0001] The present invention relates to the technical field of clothing processing, and in particular provides a clothing processing device. Background Art

[0002] With the development and progress of science and technology, more and more people are accustomed to drying clothes directly through washing machines or dryers.

[0003] When a washing machine or a clothes dryer dries clothes, the dryness of the clothes needs to be detected. Since the drying drum is usually rotating, in order to facilitate layout, the prior art usually installs the sensor on the front bracket away from the door seal of the clothes. However, when a large amount of clothes needs to be dried or the clothes are far apart, the sensor cannot come into close contact with the clothes, resulting in the inability to accurately detect the dryness of the clothes.

[0004] Accordingly, the art needs a new clothes processing device to solve the above problems. Summary of the invention

[0007] When the above technical solution is adopted, since the lifting ribs rotate with the drying drum and the contact between the lifting ribs and the clothes is more frequent and close, the dryness sensor is directly arranged on the lifting ribs, which can contact the clothes at a close distance and for a long time, thereby achieving the purpose of more accurately detecting the dryness of the clothes, especially when a large amount of clothes need to be dried or the distance between the clothes is far, it does not affect the detection result; the signal transmitting module is used to transmit the detection result of the dryness sensor, and the controller controls the operation of related programs according to the detection result after receiving the detection result; 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 transmitting coil generates a magnetic field after being energized, the receiving coil generates current due to electromagnetic induction to power the dryness sensor and the signal transmitting module. Therefore, through the fixed setting of the transmitting coil, the receiving coil is set to rotate with the drying drum, which avoids the dryness sensor and the signal transmitting module from rotating with the drying drum.

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] 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.

[0035] 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.

[0036] See first Figure 1 , which shows the cross-sectional structure of the laundry processing device of the present invention. Figure 1As shown, the clothing processing device includes a drying drum 1, a dryness sensor, a signal transmitting module 4, and a power supply component. The drying drum 1 is provided with a rotating shaft 11. The output shaft of the motor is transmission-connected to the rotating shaft 11 and drives the drying drum 1 to rotate by driving the rotating shaft 11. 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 arranged on the lifting ribs 2 in the drying drum 1, and the dryness sensor is used to detect the dryness degree of the clothes. Since the lifting ribs 2 rotate with the drying drum 1 and the contact between the lifting ribs 2 and the clothes is more frequent and close, the dryness sensor is directly arranged on the lifting ribs 2, which can contact the clothes at a close distance and for a long time, thereby achieving the purpose of more accurately detecting the dryness degree of the clothes, especially when a large amount of clothes needs to be dried or the distance between the clothes is far, it does not affect the detection result; the signal transmitting module 4 is arranged to rotate with the drying drum 1 and is communicatively connected with the dryness sensor. The signal transmitting module 4 is used to The detection result of the dryness sensor is transmitted, and the controller controls the operation of related programs according to the detection result after receiving the detection result; the power supply component includes a transmitting coil 5 and a receiving coil 6, the transmitting coil 5 is fixedly arranged, and the receiving coil 6 is installed on the drying drum 1, and the receiving coil 6 is electrically connected to the signal transmitting module 4 and the dryness sensor respectively, and the power supply component is used to provide electric energy for the dryness sensor and the signal transmitting module 4 to ensure the normal operation of the dryness sensor and the signal transmitting module 4. Since the transmitting coil 5 generates a magnetic field after being energized, the receiving coil 6 generates a current due to electromagnetic induction to power the dryness sensor and the signal transmitting module 4. Therefore, through the fixed setting of the transmitting coil 5, the receiving coil 6 is rotated with the drying drum 1, which avoids the dryness sensor and the signal transmitting module 4 rotating with the drying drum 1 and causing the line to be broken, thereby improving the safety of use, ensuring the normal operation of the dryness sensor and the signal transmitting module 4, and then achieving the purpose of accurately detecting the dryness degree of clothes.

[0037] Specifically, the transmitting coil 5 is coaxial with the rotating shaft 11 of the drying drum 1, and the transmitting coil 5 is installed on the inner side of the rear shell of the clothing processing device, and the receiving coil 6 is coaxial with the transmitting coil 5, and the receiving coil 6 is installed on the outer side of the rear wall of the drying drum 1; the receiving coil 6 is coaxially arranged with the transmitting coil 5, and both are coaxial with the rotating shaft 11 of the drying drum 1, so that during the rotation of the drying drum 1, the receiving coil 6 always remains coaxial with the transmitting coil 5, thereby making the magnetic flux of the receiving coil 6 larger than other settings, and the induction effect is better; the arrangement position of the transmitting coil 5 and the receiving coil 6 can effectively utilize the space outside the rear wall of the drying drum 1 and inside the rear shell. In addition, the close position of the transmitting coil 5 and the receiving coil 6 is conducive to the efficient induction of the receiving coil 6. Possibly, a shielding layer is arranged between the transmitting coil 5 and the rear shell, and between the receiving coil 6 and the rear wall. The setting of the shielding layer avoids electromagnetic interference and improves the efficiency and safety of induction.

[0038] It will be appreciated by those skilled in the art that although the above Figure 1 It is described that the transmitting coil 5 is installed on the inner side of the rear shell of the clothing processing device, but this is not restrictive. On a clothing processing device provided with an outer drum, such as a washing machine, a washer-dryer, etc., the transmitting coil 5 can also be arranged on the inner side of the rear wall of 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.

[0039] Continue reading Figure 1 The dryness sensor includes a sensing element 3 and a dryness chip connected to the sensing element 3. The dryness chip is in communication with a signal transmitting module 4. The sensing element 3 is mounted on the outer wall of the lifting rib 2, and the dryness chip is arranged inside the lifting rib 2. The sensing element 3 is used to sense the moisture change information in the drying drum 1, and the dryness chip is used to process the information sensed by the sensing element 3 and convert it into the dryness of the clothes. The sensing element 3 is arranged on the lifting rib 2, which helps to improve the accuracy of the sensing element 3 in detecting the dryness of the clothes. The lifting rib 2 also provides protection for the dryness chip, and achieves the purpose of waterproofing, dustproofing and bump-proofing.

[0040] Possibly, the dryness determination chip and the sensing element 3 are connected via a signal line, and the signal line is arranged through the lifting rib 2. A sealing structure such as a sealing ring, a sealant, etc. is arranged between the signal line and the lifting rib 2. A sealing structure such as a sealing gasket, a sealant, etc. is also arranged between the lifting rib 2 and the drying cylinder 1 to ensure the sealing of the space inside the lifting rib 2 and prevent water in the drying cylinder 1 from entering the lifting rib 2, thereby ensuring the normal use of the dryness determination chip and other devices in the lifting rib 2.

[0041] Optionally, the sensing element 3 is a metal sheet, which can form an electrostatic field with the drying drum 1 and sense the changes in the electrostatic field; a socket is provided on the lifting rib 2, 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 3. 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, which is used to achieve a more secure installation. In addition, in addition to being plugged and fixed on the outer wall of the lifting rib 2, the sensing element 3 can also be fixed on the outer wall of the lifting rib 2 by integral injection molding, or can be installed on the outer wall of the lifting rib 2 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 2 can be an insulating material such as plastic, or a non-insulating material. If the lifting rib 2 is a non-insulating material, an insulating layer needs to be provided between the metal sheet and the lifting rib 2 to ensure that the metal sheet can accurately sense the changes in the electrostatic field between the drying drum 1.

[0042] 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.

[0043] Specifically, the connecting wire between the receiving coil 6 and the dryness judgment chip passes through the wall of the drying drum 1 and enters the interior of the lifting rib 2. A cable protection structure is provided outside the connecting wire. The cable protection structure is used to provide protection for the connecting wire, thereby achieving the purpose of waterproofing and preventing damage. Possibly, the cable protection structure can be a cable sheath, which is sleeved outside the connecting wire. The cable protection structure can also be a cable protective shell, which is installed on the drying drum 1, and the connecting wire is passed through the cable protective shell.

[0044] Continue reading Figure 1 The power supply component also includes a power storage module, which is arranged inside the lifting rib 2. The power storage module is electrically connected to the receiving coil 6, the dryness sensor, and the signal transmitting module 4 respectively. The power storage module is used to store the electric energy generated by the induction of the receiving coil 6, and serves as a backup power supply to provide electric energy for the dryness sensor, signal transmitting module 4 and other electrical devices in the drying drum 1. When the receiving coil 6 and / or the transmitting coil 5 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 sensor, signal transmitting module 4 and other electrical devices in the drying drum 1.

[0045] It will be understood by those skilled in the art that although the above Figure 1 It is described that the dry chip and the power storage module are both arranged inside the lifting rib 2, but this is not restrictive. Those skilled in the art can also set protective shells for the dry chip and the power storage module as needed, as long as they can play a protective role. Figure 1 It is described that the sensing element 3 is arranged on the outside of the lifting rib 2, which is not restrictive. Those skilled in the art can also install the sensing element 3 directly on the inner wall of the drying drum 1 as needed, and an insulating plate is arranged between the sensing element 3 and the inner wall of the drying drum 1.

The arrangement position of the signal receiving module 8 and the signal transmitting module 4 can effectively utilize the space outside the rear wall of the drying drum 1 and the inner side of the rear shell. The short distance between the signal transmitting module 4 and the signal receiving module 8 also facilitates the rapid transmission of information.

[0047] It will be appreciated by those skilled in the art that although the above Figure 1 It is described that the signal receiving module 8 is arranged on the inner side of the rear shell of the clothing processing device, and the signal transmitting module 4 is arranged on the outer side of the rear wall of the drying drum 1, but this is not restrictive. The signal transmitting module 4 can also be arranged in the lifting rib 2 or at any position on the drying drum 1. The signal receiving module 8 can also be arranged at the upper front end of the shell of the clothing processing device, close to the controller, so as to facilitate the electrical connection and communication connection between the signal receiving module 8 and the controller. The signal receiving module 8 can also be arranged at other positions on the shell of the clothing processing device. In addition, the present invention does not limit the specific form of the signal transmitting module 4. For example, it can be any form of Bluetooth, Mesh, ZigBee, Thread, Z-Wave, NFC, Hilink, UWB, LiFi, as long as the signal can be sent. Furthermore, the clothing processing device may not be provided with a signal receiving module 8, and the signal transmitting module 4 sends the detection results to the cloud server, and the cloud server sends the detection results to the clothing processing device. These adjustments do not deviate from the principles of the present invention and are within the scope of protection of the present invention.

[0048] Possibly, the clothing processing device further includes a circuit board 7, which is disposed inside the lifting rib 2, and the dryness determination chip and the power storage module are integrated on the circuit board 7, which facilitates the electrical connection and communication connection between the dryness determination chip and the power storage module, optimizes the layout, and saves space. In addition, when the signal transmission module 4 is disposed inside the lifting rib 2, it can also be integrated on the circuit board 7.

[0049] Optionally, the clothing processing device also includes a dynamic sealing structure, and the transmitting coil 5 and the receiving coil 6 are arranged within the coverage range of the dynamic sealing structure to prevent water in the drying drum 1 from entering the above-mentioned parts and affecting the normal use of the above-mentioned parts; optionally, the dynamic sealing structure includes a first dynamic sealing ring 9 and a second dynamic sealing ring 10, the first dynamic sealing ring 9 is an annular part connected to the outer side of the rear wall of the drying drum 1, and the first dynamic sealing ring 9 is slidably connected to the rear shell of the clothing processing device, and the second dynamic sealing ring 10 is an annular part connected to the outer side of the front wall of the drying drum 1, and the second dynamic sealing ring 10 is slidably connected to the front shell of the clothing processing device.

The spiral arrangement of the wire can simplify the winding process and effectively reduce the production cost.
