[0040] Based on the problems existing in the prior art, this embodiment provides a wireless charging system for a clothes drying machine. The system is applied to the clothes drying machine and can wirelessly charge the clothes drying rod when charging is required.

[0041] The clothes drying machine referred to in this embodiment generally includes a main machine and a drying rod assembly. The main machine is generally installed on the ceiling, and the drying rod assembly is arranged below the main machine through a wire rope or other lifting parts. The drying rod assembly generally includes a plurality of drying rods for hanging clothes, such as Figure 4a and 4b As shown in , a bracket 3 is also provided between the clothes drying rod assembly 1 and the host 2. The bracket 3 can be a folding assembly such as a scissors rack. One end of the bracket is slidably mounted on the host, and the other end is movably mounted on the clothes drying rod. It mainly prevents the clothes drying rod from shaking and bears the load.

[0042] like Figure 1 As shown in the figure, the wireless charging system for clothes drying machine in this embodiment includes a wireless charging transmitter disposed on the clothes drying machine host, and a first main controller, a wireless charging receiver, a power supply unit and a wireless communication unit disposed on the clothes drying machine rod assembly. Among them:

[0043] In this embodiment, Figure 2As shown in , the wireless charging transmitter 6 can be set on one side of the clothes drying machine host and connected to the second main controller on the clothes drying machine host, and is controlled to enter the working state when the clothes drying rod assembly of the clothes drying machine is in a preset position. The clothes drying machine host is generally connected to the mains, and the mains is input and transformed and stabilized by devices such as transformers and voltage stabilizers to serve as the power supply for various electrical components in the host.

Of course, this embodiment can also use other wireless power chips, and this embodiment does not limit the specific chips used.

[0045] In this embodiment, the wireless charging receiving end is connected to the power supply unit and the first main controller, and is controlled to enter the working state when the clothes drying rod assembly is in a preset position and is opposite to the wireless charging transmitting end on the clothes drying machine host. Figure 2 As shown in the figure, the wireless charging receiving terminal 7 can be set at one end of the clothes-drying rod opposite to the wireless charging transmitting terminal on the host; when the clothes-drying rod assembly is in a preset position, the wireless charging receiving terminal on the clothes-drying rod is opposite to the wireless charging transmitting terminal, and when both are awakened, the electromagnetic waves emitted by the wireless charging transmitting terminal can be received by the wireless charging receiving terminal.

[0046] In this embodiment, Figure 3bAs shown in , the wireless charging receiving end includes a receiving coil and a wireless power receiving unit; the receiving coil is opposite to the transmitting coil of the wireless charging transmitting end, and can receive the electromagnetic wave signal emitted by the transmitting coil. The wireless power receiving unit is connected to the receiving coil to convert the electrical signal output by the receiving coil; in this embodiment, the output end of the wireless power receiving unit is connected to the power supply unit, and the power supply unit can be charged through the charging circuit; the wireless power receiving unit is connected to the first main controller, and its working state is controlled by the first main controller. In this embodiment, the wireless power receiving unit can use the wireless power receiving chip T3168 chip, the input end of the T3168 chip is connected to the receiving coil, and is used to obtain the electrical signal converted by the receiving coil. The output end of the T3168 chip is connected to the power supply unit through the charging circuit, and is used to charge the power supply unit. The enable end of the T3168 chip is connected to the first main controller, and the working state is controlled by the first main controller. Of course, this embodiment can also use other wireless power receiving chips, and this embodiment does not limit the specific chip used.

[0047] In this embodiment, the first main controller and the wireless communication unit are both connected to the power supply unit, and the power supply unit is used for power supply. The first main controller is connected to the wireless communication unit, and a wireless communication connection is established with the second main controller on the clothes drying machine host through the wireless communication unit; in this embodiment, the power supply unit can be a rechargeable battery, and the first main controller is connected to the battery output terminal through the power detection unit, and can detect the battery power information, and the power detection unit can be a voltage acquisition circuit; the wireless communication unit can be a communication module such as Bluetooth, Zigbee, WiFi, etc. Specifically, the first main controller and the second main controller are both connected to a wireless communication unit, such as a first Bluetooth module and a second Bluetooth module, respectively, and the two establish a communication connection based on the first Bluetooth module and the second Bluetooth module.

[0048] like Figure 2 As shown in , the drying rod assembly 1 generally includes one or more drying rods. In order to make the drying rods retractable to suit different drying needs and use environments, a movable rod 11 that can be retracted relative to the drying rod can be added on the basis of the original drying rod. When the drying amount needs to be increased, the movable rod 11 can be extended to extend the length of the drying rod. When the drying amount is small, the movable rod can be retracted to the drying rod, saving the space occupied by the drying rod of the clothes drying machine. In this embodiment, movable rods can be respectively provided at both ends of the drying rod, and the first main controller on the drying rod is connected to the movable rod through a driving module, which can realize automatic extension and retraction control of the movable rod, overcoming the inconvenience caused by the need to manually pull the movable rod in the prior art.

[0049] In this embodiment, the above-mentioned driving module 12 can be realized by a motor driving chip and a motor. Specifically, the first main controller 13 on the clothes-drying rod is connected to the motor through the motor driving chip, and the motor output shaft is connected to the movable rod. When the motor rotates, the movable rod is driven to perform telescopic activities. Specifically, the motor output shaft can be connected to a screw structure, and an internal thread structure is installed inside the movable rod. When the motor output shaft rotates, the movable rod can be controlled to perform linear telescopic movements. Of course, other structures can also be arranged between the motor output shaft and the movable rod, as long as the structure can realize the conversion of the motor rotation into the linear motion of the movable rod, and this embodiment does not limit it.

[0050] In this embodiment, the above-mentioned driving module can also be realized by a solenoid valve and a telescopic cylinder. Specifically, the first main controller on the drying rod is connected to the solenoid valve, and the solenoid valve is arranged on the air path of the telescopic cylinder. The first main controller can control the telescopic action of the telescopic cylinder through the solenoid valve. The movable rod is arranged on the telescopic cylinder, and performs telescopic movement under the drive of the telescopic cylinder.

[0051] For some clothes drying machines with movable rods on the drying rods, when the drying rods rise to the upper limit of the preset position, the movable rods may collide with the main machine or the ceiling. Therefore, if the drying rods need to be controlled to rise to the preset position for charging, the movable rods need to be controlled to retract by the first main controller. It can be seen that the above-mentioned automatic control method of the movable rods in this embodiment can effectively overcome the occurrence of collisions of the movable rods.

[0052] In this embodiment, the clothes drying machine wireless charging system may further include a load detection unit connected to the first main controller, the load detection unit is arranged on the movable rod, and is used to detect the load information of the movable rod, and transmit the detected load information to the second main controller through the first main controller. In this embodiment, the load detection unit is arranged on the movable rod mainly to detect whether there are clothes drying on the movable rod; the load detection unit may be a weighing sensor, which is connected to the first main controller, and is used to transmit the weight information on the detected movable rod to the first controller, and when the weight on the movable rod exceeds the preset value, it is determined that there are clothes drying on the movable rod. In addition, the load detection unit may also be an infrared sensor, a laser sensor, an ultrasonic sensor, etc. Specifically, the load detection unit includes a light source transmitting end and a receiving end, and the receiving end is connected to the first main controller, and is used to receive the light signal emitted by the light source transmitting end; the light source transmitting end and the receiving end are respectively arranged at both ends of the movable rod, and the clothes hung on the movable rod can block the light signal emitted by the light source transmitting end to the receiving end, so when there are clothes drying on the movable rod, the load detection unit will feedback the corresponding signal to the first main controller to determine that there is a load on the movable rod.

[0053] When the first main controller controls the movable rod to retract, if there are clothes hanging on the movable rod, the movable rod will be unable to retract or even damaged. Based on this, the present embodiment provides a load detection unit for detecting whether there are clothes hanging on the movable rod; when it is necessary to control the drying rod to rise to a preset position for charging, first determine whether the movable rod is extended. If extended, based on the load detection unit, it can be determined whether there is weight on the movable rod (that is, whether there are clothes hanging). If so, a prompt message is sent through the first main controller to remind the user to take off the clothes on the movable rod to avoid damage caused by retraction in this situation.

[0054] In this embodiment, the clothes drying machine wireless charging system may further include a position detection unit connected to the first main controller or the second main controller, the position detection unit is used to detect the position of the clothes drying rod assembly, and send the detected position information to the first main controller or the second main controller, and the first main controller or the second main controller can determine whether the clothes drying rod assembly has reached the preset position according to the received position information. Figure 4a As shown in , the position detection unit can be a mechanical micro switch 4 provided on the host and connected to the second main controller. When the drying rod assembly reaches a preset position, such as the upper limit, the bracket will touch the mechanical micro switch. Specifically, when the drying rod assembly moves, such as rising, and the bracket (scissors rack) shrinks to a certain extent, the sliding end 31 of the bracket installed on the host side will touch the mechanical micro switch, and the mechanical micro switch will send a signal to the second main controller, so as to determine that the drying rod assembly has reached the preset position. In addition, as Figure 4b As shown in, in another embodiment, the position detection unit can also be a distance sensor 5 installed on the host side or the drying rod side, such as a laser transmitting and receiving device, an infrared transmitting and receiving device, an ultrasonic transmitting and receiving device or a radar transmitting and receiving device. When the distance sensor is installed on the host, it is connected to the second main controller in the host, and the transmitting end of the distance sensor faces the sliding end at the position of the bracket corresponding to the host, and transmits a signal to the sliding end. When it is detected that the distance is less than the set value, it is determined that the bracket has retracted to a certain extent and the drying rod assembly has reached the preset position; when the distance sensor is installed on the drying rod assembly, it is connected to the first main controller on the drying rod assembly, and the transmitting end of the distance sensor faces the sliding end at the position of the bracket corresponding to the drying rod assembly, and transmits a signal to the sliding end. When it is detected that the distance is less than the set value, it is determined that the bracket has retracted to a certain extent and the drying rod assembly has reached the preset position. Of course, in this embodiment, the position detection unit can also be other devices, such as a grating sensor, an encoder or a Hall sensor set on the motor for detecting the number of motor rotations. The travel of the drying rod assembly can be determined based on the number of motor rotations detected by the grating sensor, the encoder or the Hall sensor, and then the position of the drying rod assembly can be determined. In this embodiment, the position detection unit can accurately determine whether the clothes drying rod assembly has reached a preset position, which can serve as a condition for triggering wireless charging.

[0055] In this embodiment, the first main controller and the second main controller can use chips with processing and control functions such as single-chip microcomputers. The first main controller and / or the second main controller can establish a communication connection with an external user terminal through a wireless communication module to realize user interaction, such as sending prompt information, alarm information, information that the power supply unit is low on power or that the power supply unit is fully charged to the user terminal, or receiving some control instructions sent by the user terminal, including clothes drying machine lifting and stopping instructions, charging instructions, lighting / disinfection function on and off instructions, etc.

[0056] In summary, in the wireless charging system of this embodiment, when the clothes drying rod is controlled to perform lifting movement relative to the main unit and is in a preset position, the wireless charging transmitter and the wireless charging receiver are positioned relative to each other. At this time, the wireless charging transmitter and the wireless charging receiver can be controlled to enter a working state, and the electromagnetic waves emitted by the wireless charging transmitter can be received by the wireless charging receiver and converted into electric current to charge the power supply unit on the clothes drying rod; based on this, the wireless charging system of this embodiment can realize wireless charging of the clothes drying rod when there is a charging demand, without the need for the charging system to be in standby state all the time, thereby ensuring that the appearance of the clothes drying machine is not affected while also ensuring the safety of the clothes drying machine's electricity use.

[0057] Furthermore, in the wireless charging system of the present embodiment, the first main controller on the drying rod assembly can detect the power information of the power supply unit through the power detection unit. Based on this, when the drying rod assembly reaches the preset position, it can first determine whether the power of the power supply unit is lower than the set value, that is, whether there is a power shortage situation. If so, the wireless charging transmitter and the wireless charging receiver are awakened respectively through the second main controller and the first main controller.

[0058] Furthermore, in the wireless charging system of this embodiment, the first main controller can detect the power information of the power supply unit in real time through the power detection unit. When the power supply unit is insufficient, a charging instruction can be sent to the second main controller, and the second main controller controls the drying rod assembly to rise to a preset position.

[0059] Furthermore, in the wireless charging system of the present embodiment, the power supply unit on the clothes-drying rod assembly can be wirelessly charged through the host side when it is out of power or insufficiently charged, so that other functional modules that need to be powered can be set on the clothes-drying rod assembly, such as drive modules such as motors serving as a power system. Based on this, automatic control of the extension and retraction of the movable rod on the clothes-drying rod assembly can be achieved, overcoming the inconvenience caused by manual operation required in the prior art.

[0060] Furthermore, the wireless charging system of the present embodiment may include a load detection unit arranged on the movable rod, and the like. Based on the load detection unit, it can be determined whether there are clothes hanging on the movable rod. If the structural design of the clothes drying machine must meet the requirement that the rod assembly can only run to a preset position such as the upper limit position when the movable rod is retracted, the system of the present embodiment can determine whether to control the current state of the movable rod based on the load detection unit to ensure the safety of the operation of the clothes drying machine.

[0061] This embodiment 2

[0062] This embodiment discloses a clothes drying machine, including a main machine, a clothes drying rod assembly, a power system, and the wireless charging system described in Embodiment 1. Among them:

[0063] The drying rod assembly is used for drying clothes. The drying rod assembly is arranged under the main machine through the power system and can be lifted and lowered under the drive of the power system. The main machine of the clothes drying machine is fixed in the installation environment, such as the ceiling of the fixed balcony. The main machine is provided with a second main controller, a drying module, a lighting module, etc. The power system of the clothes drying machine may include a motor, a winding wheel, a pulley assembly, a wire rope, etc. The second main controller is connected to the motor through a motor driver to control the rotation of the motor. The winding wheel is connected to the motor output shaft in a transmission manner. One end of the wire rope is arranged on the winding wheel, and the other end passes through the pulley in the pulley assembly and changes direction (changes the horizontal direction to the vertical direction) and is fixedly connected to the drying rod assembly under the main machine. The winding wheel is driven by the motor to rotate so as to be able to retract and release the wire rope, thereby driving the drying rod assembly on the wire rope to rise or fall. In addition, the second main controller can be connected to functional modules such as a drying module, a lighting module, and a disinfection module to control the working state of the drying module, the lighting module, and the disinfection module. Of course, the power system in the clothes drying machine of this embodiment can also be a telescopic rod or other structural type, that is, the clothes drying rod assembly is arranged below the clothes drying machine main body through the telescopic rod, and the clothes drying rod assembly can move up and down under the telescopic action of the telescopic rod.

[0064] The clothes-drying rod assembly generally includes one or more clothes-drying rods and parts for drying such as drying baskets and drying frames. The clothes-drying rods include conventional clothes-drying rods, quilt-drying rods, small clothes-drying rods, etc. Conventional clothes-drying rods refer to clothes-drying rods with hanging holes for hanging clothes hangers. Quilt-drying rods refer to clothes-drying rods used for drying quilts, which can be set as a hidden structure and can be hidden on the clothes-drying rod assembly when not in use to avoid affecting normal drying. Small clothes-drying rods refer to short rods that are set between conventional clothes-drying rods and are usually provided with clothespins. This embodiment does not limit the specific structure of the clothes-drying rod assembly.

[0065] In this embodiment, in order to extend the drying capacity of the clothes drying rod (such as the conventional clothes drying rod mentioned above), movable rods are added to both ends of the clothes drying rod, and the movable rods can be telescopic relative to the clothes drying rod. Since the clothes drying machine in this embodiment adopts the wireless charging system described in Example 1, the electrical components on the clothes drying rod can be powered by the power supply unit. Therefore, in this embodiment, the movable rod is connected to the first main controller on the clothes drying rod assembly through the driving module. Based on the first main controller, the movable rod can be automatically controlled, which overcomes the inconvenience caused by manual control of the movable rod in the prior art. The specific structure and composition of the movable rod and the driving module can refer to Example 1, which will not be repeated here.

[0066] The clothes drying machine in this embodiment, based on the power supply function of the power supply unit on the clothes drying rod assembly, can also be provided with functional modules such as lighting, drying, and disinfection on the clothes drying rod assembly.
