Description

Technical Field

[0001] The present invention relates to the technical field of clothing processing equipment, and specifically provides a drying drum assembly and clothing processing equipment. 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 drying drum assembly to solve the above problems. Summary of the invention

[0005] The present invention aims to solve the above technical problem, that is, to solve the problem in the prior art that the sensor cannot come into close contact with the clothes and cannot accurately detect the dryness of the clothes because the drying drum is rotating. In a first aspect, the present invention provides a drying drum assembly, comprising: a drying drum, which is rotatable; a dryness sensor, which is used to detect the degree of dryness of clothes and is arranged in the drying drum; a signal transmitting module, which is arranged to rotate with the drying drum and is communicatively connected with the dryness sensor; and a power supply component, which is arranged to rotate with the drying drum and is electrically connected to the signal transmitting module and the dryness sensor, respectively.

[0006] When the above technical solution is adopted, the dryness sensor is directly arranged in the drying drum and can contact the clothes at a close distance, so as to detect the dryness degree of the clothes more accurately; the signal transmitting module is used to transmit the detection result of the dryness sensor, which is received by the signal receiving module, and the power supply component is arranged to rotate with the drying drum to provide power to the dryness sensor and the signal transmitting module, thereby ensuring the normal operation of the dryness sensor and the signal transmitting module, and solving the line connection and layout problems caused by the dryness sensor being arranged in the drying drum and rotating with the drying drum.

[0007] In a specific embodiment of the above-mentioned drying drum assembly, the power supply component includes a generator, and the generator includes a coil and a magnet. The generator is configured so that when the drying drum rotates, the magnet reciprocates under the rotation of the drying drum, and the magnetic flux of the coil changes to generate current.

[0008] When the above technical solution is adopted, the rotation of the drying drum drives the magnet to reciprocate, causing the magnetic flux of the coil to change, thereby generating current in the coil to provide power for the dryness sensor and the signal transmission module. At the same time, the kinetic energy of the rotation of the drying drum is fully utilized, and there is no need to connect to an external power supply. This solves the problem of power source and reduces energy consumption.

[0009] In a specific embodiment of the above-mentioned drying drum assembly, the power generating element also includes a sleeve frame, the coil is sleeved outside the sleeve frame, the magnet is arranged in the sleeve frame and can move axially along the sleeve frame, and the axis of the sleeve frame is perpendicular to or at an acute angle to the axis of the drying drum.

[0010] When the above technical solution is adopted, the sleeve frame provides support for the coil and also provides guidance for the movement of the magnet, so that the movement of the magnet causes the change of magnetic flux in the coil to generate current. In addition, the axis of the sleeve frame is perpendicular to or at an acute angle to the axis of the drying drum, so that when the drying drum rotates, the magnet can move along the axial direction of the sleeve frame. Every time the drying drum rotates half a circle, the magnet moves from one end of the sleeve frame to the other end.

[0011] In a specific embodiment of the above drying drum assembly, buffer members are provided at both ends of the sleeve frame.

[0012] When the above technical solution is adopted, when the magnet reciprocates in the sleeve frame, it directly hits the buffer part, which can play a role in shock absorption and noise reduction. At the same time, it can also protect the magnet, reduce the damage to the magnet caused by the impact, and increase the service life.

[0013] In a specific embodiment of the above-mentioned drying drum assembly, the drying drum assembly further comprises lifting ribs arranged on the inner wall of the drying drum, and the dryness determination sensor, the signal transmitting module and the power generation element are all arranged on the lifting ribs.

[0014] 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 arranged on the lifting ribs, which helps the dryness sensor to detect the dryness of the clothes and make the detection result more accurate.

[0015] In a specific embodiment of the above-mentioned drying drum assembly, the dryness sensor includes a sensing element and a dryness chip electrically connected to the sensing element, the sensing element is mounted on the outer wall of the lifting rib, the dryness chip, the signal transmitting module and the power generating element are all arranged inside the lifting rib, and the dryness chip is communicatively connected to the signal transmitting module.

[0016] When adopting the above technical solution, the dryness detection chip is installed on the outer wall of the lifting rib, which can come into close contact with the clothes in the drying drum to make the detection result more accurate. The dryness detection chip, signal transmission module and power generation device are arranged inside the lifting rib, which can provide them with protection and achieve the purpose of waterproofing, anti-fouling and damage prevention.

[0017] In a specific embodiment of the drying drum assembly, the sensing element is a metal sheet, the lifting rib is provided with a plug hole, and the end of the metal sheet is bent and plugged into the plug hole for fixation.

[0018] When the above technical solution is adopted, the sensing element is plugged and fixed to the lifting rib, which facilitates the disassembly, maintenance and replacement of the sensing element.

[0019] In a specific embodiment of the above-mentioned drying drum assembly, the power supply component also includes a power storage module arranged inside the lifting rib, and the power storage module is electrically connected to the coil, the dryness determination sensor, and the signal transmission module respectively.

[0020] When the above technical solution is adopted, the power storage module is used to store the electric energy generated by the power generation element, so as to provide real-time power to the dryness sensor and the signal transmission module, and can also maintain power supply for a period of time when the drying drum is not rotating.

[0021] In a specific embodiment of the above-mentioned drying drum assembly, the drying drum assembly further includes a circuit board disposed inside the lifting ribs, and the dryness determination chip, the signal transmission module and the power storage module are all integrated on the circuit board.

[0022] When the above technical solution is adopted, the electrical connection and communication connection of the detection chip, the signal transmission module and the power storage module are facilitated, the layout is optimized and the space is saved.

[0023] In a second aspect, the present invention further provides a clothes processing device, the clothes processing device includes the drying drum assembly, the clothes processing device also includes a signal receiving module, and the signal transmitting module is communicatively connected to the signal receiving module.

[0030] Some embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not used to limit the scope of protection of the present invention. Those skilled in the art can make adjustments to them as needed to adapt to specific application scenarios.

[0031] It should be noted that in the description of the present invention, the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, which are only for the convenience of description, and do not indicate or imply that the relevant devices or elements must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. 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 drying drum assembly and a clothing processing device, which aims to achieve close contact with the clothes and thus accurately detect the dryness degree of the clothes by arranging the dryness sensor in the drying drum.

[0034] See first Figure 1 , the figure shows the cross-sectional structure of the clothing processing device of the present invention, the clothing processing device includes a drying drum assembly, a signal receiving module 6, the clothing processing device can be a washing machine, a washer-dryer, a clothes dryer, a drying machine and other devices that can dry clothing, and no specific limitation is made here.

[0035] The drying drum assembly includes a drying drum 1, a dryness sensor, a signal transmitting module, and a power supply component; the drying drum 1 is rotatably arranged, and clothes to be dried are placed in the drying drum 1. The clothes are dried while the drying drum 1 rotates, so that the clothes can be fully dried and the drying efficiency is improved; the dryness sensor is arranged in the drying drum 1, and can detect the dryness of the clothes at a close distance, thereby realizing accurate dryness judgment; the signal transmitting module is communicatively connected with the dryness sensor, and is used to transmit the detection result of the dryness sensor, which is received by the signal receiving module 6 and fed back to the controller of the clothing processing device, and the controller then 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; or the signal transmitting module sends the detection result to the cloud server, and the cloud server sends the detection result to the clothing processing device; the power supply component includes a power generation component 2, which can generate electrical energy through the rotation of the drying drum 1, and the power generation component 2 is electrically connected to the signal transmitting module and the dryness sensor respectively, and is used to provide electrical energy for the signal transmitting module and the dryness sensor. Moreover, the dryness sensor, the signal transmitting module and the power generating element 2 are all arranged to rotate with the drying drum 1, which solves the line connection and layout problems caused by the dryness sensor being arranged in the drying drum 1 and improves the safety of use. If only the dryness sensor is arranged in the drying drum 1, and the signal transmitting module and the power generating element 2 do not rotate with the drying drum 1, the connecting wires can easily be caught in the drying drum 1 due to the rotation of the drying drum 1, causing damage to the wires or even serious accidents such as leakage and fire.

[0036] It will be understood by those skilled in the art that the present invention does not limit the specific form of the signal transmission module. For example, it can be any form of Bluetooth, Mesh, ZigBee, Thread, Z-Wave, NFC, Hilink, UWB, and LiFi. As long as the signal can be sent, it does not deviate from the principle of the present invention and is within the protection scope of the present invention. In addition, as a possible implementation method, the dryness sensor is a 3D perspective drying sensor, which can emit countless electric field lines to the wall of the drying drum to form a bipolar 3D detection field to dynamically scan the clothes. 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.

[0037] In addition, in addition to using the power generation device 2 to generate electrical energy through the rotation of the drying drum 1, the power supply component can also directly use batteries for power supply. However, when using batteries for power supply directly, due to the limited capacity of the battery, it needs to be replaced frequently with use, which causes inconvenience to the user. By using the power generation device 2 for power supply, the power generation device 2 can convert the kinetic energy of the rotation of the drying drum 1 into electrical energy. As long as the drying drum 1 rotates, it can continuously provide electrical energy for the signal transmission module and the dryness judgment sensor, thereby making full use of the kinetic energy of the rotation of the drying drum 1, solving the problem of the source of electrical energy while reducing energy consumption and saving costs.

[0038] The power supply component also includes a power storage module, which is electrically connected to the power generation element 2, the dryness sensor, and the signal transmission module respectively. The power storage module stores the electric energy generated by the power generation element 2 and continuously supplies the dryness sensor and the signal transmission module. Since the power generation element 2 converts the kinetic energy of the rotation of the drying drum 1 into electric energy, the power generation element 2 can only generate electricity when the drying drum 1 rotates. When the drying drum 1 rotates slowly or stops rotating, the power generation will be discontinuous or interrupted. When the drying drum 1 rotates faster, the power generation element 2 generates more electric energy, and the excess electric energy can be transmitted to the power storage module and stored. When the power generation element 2 generates less electric energy or stops generating electricity, the continuous supply of electric energy can still be guaranteed.

[0039] See below Figure 1 and Figure 2 , Figure 2 The overall structure of the lifting rib 3 of the present invention is shown. Possibly, the dryness sensor includes a sensing element 5 and a dryness chip electrically connected to the sensing element 5. The dryness sensor is a capacitive sensor, the sensing element 5 is a humidity-sensitive element, and the power generation element 2 provides power for the dryness sensor. When the sensing element 5 is powered on, the capacitance of the sensing element 5 changes with the humidity in the drying drum 1. The dryness chip converts the capacitance value corresponding to the sensing element 5 into a humidity value to detect the dryness of the clothes. The drying drum assembly also includes a lifting rib 3 disposed on the inner wall of the drying drum 1. The lifting rib 3 is a hollow shell. The sensing element 5 is installed on the outer wall of the lifting rib 3. The dryness chip, the signal transmitting module, the power generation element 2, and the storage module are all disposed inside the lifting rib 3. When the drying drum 1 rotates, the lifting ribs 3 continuously push the clothes upward. When the clothes move to a certain height, the clothes fall from the lifting ribs 3 to the bottom of the drying drum 1 under the action of gravity. In the process of the lifting ribs 3 pushing the clothes, the lifting ribs 3 will fit closely with the clothes, and the contact time between the lifting ribs 3 and the clothes is relatively long. Therefore, the sensing element 5 installed on the outer wall of the lifting ribs 3 will also fit closely with the clothes and fit for a certain time. Thereby, no matter how much clothes there are, the sensing element 5 can closely and fully detect the dryness of the clothes, thereby achieving the purpose of accurate dryness judgment.

[0040] At the same time, the dryness detection chip, signal transmission module, power generation device 2, and power storage module are all arranged inside the lifting rib 3, and their protection can be achieved by the lifting rib 3. Since the lifting rib 3 is usually a sealed structure, the dryness detection chip, signal transmission module, power generation device 2, and power storage module inside the lifting rib 3 can also be waterproof, anti-fouling and prevented from damage.

[0041] It will be understood by those skilled in the art that although the above Figure 1 and Figure 2 It is described that the dryness sensor, signal transmission module, power generation device 2, and power storage module are all arranged on the lifting rib 3, but this is not restrictive. Those skilled in the art can also provide a protective shell for the dryness sensor, signal transmission module, power generation device 2, and power storage module together or separately as needed, and directly install them on the inner wall or outer wall of the drying drum 1. As long as the dryness sensor, signal transmission module, power generation device 2, and power storage module can rotate with the drying drum 1 and can be protected, this adjustment does not deviate from the principle of the present invention and will therefore fall within the protection scope of the present invention. In addition, although the above combination Figure 1 and Figure 2 It is described that the sensing element 5 is arranged on the outer wall of the lifting rib 3, which is not restrictive. A person skilled in the art can also directly install the sensing element 5 on the inner wall of the drying drum 1 as needed, and the sensing element 5 can also contact the clothes at a close distance, so as to accurately detect the dryness of the clothes. However, compared with the sensing element 5 being arranged on the outer wall of the lifting rib 3, the lifting rib 3 can make the sensing element 5 contact with the clothes longer and more fully.

[0042] In addition, preferably, the drying drum assembly also includes a circuit board 4 arranged inside the lifting rib 3, the dryness determination chip, the signal transmission module, and the power storage module are integrated on the circuit board 4, the circuit board 4 is electrically connected to the sensing element 5, and the circuit board 4 is electrically connected to the power generation element 2. The arrangement of the circuit board 4 facilitates the connection between the dryness determination chip, the signal transmission module, and the power storage module, optimizes the layout, and saves space; those skilled in the art can also separately arrange the dryness determination chip, the signal transmission module, and the power storage module as needed, and achieve connection through electrical connection and / or communication connection. In addition, in addition to being arranged inside the lifting rib 3, the circuit board 4 can also be provided with a protective shell on the circuit board 4, and directly arranged on the inner wall of the drying drum 1 or the outer wall of the drying drum 1, as long as the circuit board 4 rotates with the drying drum 1.

[0043] Last read Figure 3, the figure shows the cross-sectional structure of the lifting rib 3 and the power generation element 2 of the present invention, the power generation element 2 includes a sleeve frame 21, a coil 22, and a magnet 23, the coil 22 is sleeved outside the sleeve frame 21, the sleeve frame 21 is a hollow structure, the sleeve frame 21 is fixed relative to the lifting rib 3, the magnet 23 is arranged in the sleeve frame 21 and moves along the axial direction of the sleeve frame 21, the axis of the sleeve frame 21 is perpendicular to the axis of the drying drum 1 or at an acute angle; the sleeve frame 21 provides support for the coil 22 and also provides guidance for the movement of the magnet 23, and the magnet 23 causes the magnetic flux in the coil 22 to change during the movement, thereby generating current. In addition, the axis of the sleeve frame 21 is perpendicular to or at an acute angle to the axis of the drying drum 1, so that when the drying drum 1 rotates, the magnet 23 can move along the axial direction of the sleeve frame 21. Every time the drying drum 1 rotates half a circle, the magnet 23 moves from one end of the sleeve frame 21 to the other end. Every time the magnet 23 moves, the magnetic flux in the coil 22 changes, thereby generating current. A circuit board 4 is also provided inside the lifting rib 3. The circuit board 4 is fixedly installed with the inner wall of the lifting rib 3 or with the inner wall of the drying drum 1 inside the lifting rib 3. The circuit board 4 is electrically connected to the coil 22, and the electric energy generated by the coil 22 can be transmitted to the power storage module on the circuit board 4 in real time to store the electric energy.

[0044] Buffers 24 are provided at both ends of the sleeve frame 21. When the magnet 23 reciprocates in the sleeve frame 21, it directly hits the buffer 24, which can reduce shock and noise, and also protect the magnet 23, reduce damage to the magnet 23 caused by the impact, and increase the service life. Preferably, the buffer 24 is a flexible or elastic member, such as a rubber block, a spring, etc.

[0045] It should be noted that the moving direction of the magnet 23 can be set parallel to the axis of the coil 22, or it can be set at an acute angle to the axis of the coil 22, as long as the magnet 23 can change the magnetic flux in the coil 22 during the movement, thereby generating an electric current, and those skilled in the art can make adjustments according to actual needs. In addition, the radial cross-section of the sleeve skeleton 21 can be circular, square or other arbitrary shapes, all within the protection scope of the present invention. Specifically, the magnet 23 can be a permanent magnet, or an electromagnet or other device or mechanism that can generate a magnetic field. The sleeve skeleton 21 is arranged inside the lifting rib 3, and the sleeve skeleton 21 can be directly fixedly installed with the lifting rib 3, or it can be fixedly installed on the inner wall of the drying drum 1 inside the lifting rib 3.

[0046] Regarding the power generating element 2, although the above Figure 3It is described that the magnet 23 reciprocates with the rotation of the drying drum 1, but this is not restrictive. Those skilled in the art can also set it as needed that the magnet 23 is fixed relative to the lifting rib 3, and the coil 22 reciprocates relative to the magnet 23 with the rotation of the drying drum 1. During the movement of the coil 22, the magnetic flux lines of the magnetic field generated by the magnet 23 are cut, thereby generating current; it can also be set that the coil 22 is set at the axis of the drying drum 1, the axis of the coil 22 is coaxial with the axis of the drying drum 1 and rotates with the rotation of the drying drum 1, the magnet 23 is set on a non-rotating part of the clothing processing device, and the magnetic flux lines of the magnetic field generated by the magnet 23 are cut during the rotation of the coil 22. The induction line generates current, and the coil 22 and the dryness sensor rotate together with the drying drum 1, and there will be no problem with the line layout; it can also be arranged that the coil 22 and a magnet 23 rotate with the drying drum 1, and a magnet 23 is also arranged on the non-rotating part of the clothing processing device. When the drying drum 1 rotates, each rotation, the two magnets 23 will have a process of approaching and then moving away. In this process, the magnetic flux in the coil 22 changes, thereby generating current; or other methods of converting kinetic energy into electrical energy. Those skilled in the art can make adjustments as needed. These adjustments do not deviate from the principles of the present invention, and therefore will also fall within the scope of protection of the present invention. In addition, the number of power generation components 2 can be set to one, or it can be set to multiple to generate electricity simultaneously, thereby improving the power generation efficiency.

Among them, the sensing element 5 passes through the bent part of the socket and is electrically connected to the circuit board 4 in the lifting rib 3. It should be noted that one or more sockets can be provided on the lifting rib 3, corresponding to the number of bending structures of the metal sheet, and those skilled in the art can adjust it according to specific needs. In addition to being plugged and fixed on the outer wall of the lifting rib 3, the sensing element 5 can also be installed on the outer wall of the lifting rib 3 by bolts, or bonded to the outer wall of the lifting rib 3, or other installation methods, as long as it is installed and fixed on the outer wall of the lifting rib 3.
