[0061] The embodiments of this utility model will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be understood that the preferred embodiments are only for illustrating this utility model and not for limiting the scope of protection of this utility model.

[0062] Traditional clothes drying racks typically use a shared power supply for both the motor and lighting load. However, because the power ratings of the motor and lighting load are different, the overall efficiency and individual load efficiency of the clothes drying rack are both relatively low. For example, the lighting load might have a power rating of 15W-30W, while the motor's stable operating power is 50W-80W. At startup, the motor's power consumption is approximately 60W-120W. The power supply needs to be designed for maximum power, i.e., 60W-120W, resulting in low power efficiency when the clothes drying rack is solely supplying the lighting load, sometimes even below 75%. Furthermore, considering the specific application scenario, the lighting load typically runs the longest, further reducing the clothes drying rack's power efficiency. In short, sharing a power supply for both the motor and lighting load in a clothes drying rack leads to low power efficiency.

[0063] To address the low power efficiency issue inherent in existing clothes drying racks where the motor and lighting load share a single power supply, this application provides a clothes drying rack power system and a clothes drying rack. A power input module provides a power signal, enabling the motor control module to output a working voltage signal to the main control module based on this signal. Based on the power signal and the motor control signal output by the main control module, the main control module outputs a first power supply signal to the clothes drying rack's motor to power it. Simultaneously, the main control module outputs lighting control and motor control signals based on the working voltage signal, allowing the lighting control module to output a second power supply signal to the clothes drying rack's lighting load based on the power signal and the lighting control signal output by the main control module. This provides independent power control for the clothes drying rack's lighting load and motor, effectively improving the clothes drying rack's power efficiency and resolving the low power efficiency problem inherent in existing clothes drying racks where the motor and lighting load share a single power supply.

[0064] Figure 1 This is a schematic diagram of a power supply system for a clothes drying rack, provided as an embodiment of this application.

[0065] like Figure 1As shown in the illustration, an embodiment of this application provides a clothes drying rack power supply system, which specifically includes: a power input module 11, a lighting control module 12, a motor 16 control module 13, and a main control module 14; wherein, the first and second terminals of the power input module 11 are electrically connected to the first terminals of the lighting control module 12 and the motor 16 control module 13, respectively, for providing power signals; the second terminal of the motor 16 control module 13 is electrically connected to the first terminal of the main control module 14, for outputting a working voltage signal to the main control module 14 according to the power signal; and outputting a first power supply signal to the motor 16 of the clothes drying rack based on the power signal and the motor 16 control signal output by the main control module 14; the second terminal of the lighting control module 12 is electrically connected to the second terminal of the main control module 14, for outputting a second power supply signal to the lighting load 15 of the clothes drying rack according to the power signal and the lighting control signal output by the main control module 14; the third terminal of the main control module 14 is electrically connected to the third terminal of the motor 16 control module 13, for outputting a power supply signal based on the working voltage signal. The control signal for motor 16 is as follows: the first terminal of the power input module 11 is electrically connected to the first terminal of the lighting control module 12, the second terminal of the power input module 11 is electrically connected to the first terminal of the motor 16 control module 13, the second terminal of the motor 16 control module 13 is electrically connected to the first terminal of the main control module 14, the second terminal of the main control module 14 is electrically connected to the second terminal of the lighting control module 12, and the third terminal of the main control module 14 is electrically connected to the third terminal of the motor 16 control module 13; the power input module 11 is used to provide a power signal; the motor 16 control module 13 is used to output a working voltage signal to the main control module 14 based on the power signal; and output a first power supply signal to the motor 16 of the clothes dryer based on the power signal and the motor 16 control signal output by the main control module 14; the lighting control module 12 is used to output a second power supply signal to the lighting load 15 of the clothes dryer based on the power signal and the lighting control signal output by the main control module 14; the main control module 14 is used to output a lighting control signal and a motor 16 control signal based on the working voltage signal.

[0066] As can be seen, in this embodiment, the lighting control signal output by the main control module 14 and the power signal output by the power input module 11 are used to control the lighting load 15 separately; and the motor 16 control signal output by the main control module 14 and the power signal output by the power input module 11 are used to control the motor 16 separately. Thus, the power output control of the motor 16 and the lighting load 15 can be performed separately, thereby effectively improving the power efficiency of the clothes drying rack. This solves the problem of low power efficiency in the prior art where the motor 16 and the lighting load 15 of the clothes drying rack share a single power supply.

[0067] Furthermore, based on the above embodiments, such as Figure 2As shown, the main control module 14 in this embodiment may include a main control unit 141 and a switch unit 142.

[0075] In conjunction with the above embodiments, in specific implementation, after the MCU receives the working voltage signal 5V, since the MCU is in the secondary circuit and the dimming IC is in the primary circuit, the main control module 14 controls the VDD of the first dimming chip (powered by the auxiliary winding of the constant voltage switching power supply) through the optocoupler U7.

[0082] In conjunction with the above embodiments, in specific implementation, after the MCU receives the 5V operating voltage signal, the MCU controls the motor 16 to lift and the LED lighting switch and dimming. The LED switching circuit is controlled by optocoupler transmission. Optocoupler U7 controls the VDD of the dimming IC (powered by the auxiliary winding of the constant voltage switching power supply). When the MCU outputs LED_EN low level, optocoupler U7 is not conducting, the dimming constant current IC U6 does not work without VDD power supply, and U4 also does not work, reducing standby power consumption; when the MCU outputs LED_EN high level, optocoupler U7 conducts, U6 has VDD power supply and starts working, that is, both the single-stage PFC constant voltage switching power supply and the BUCK dimming constant current circuit start working. The MCU then outputs PWM to U4, the lighting LED lights up, and PWM dimming can be performed.

[0083] In conjunction with the above embodiments, in specific implementation, after the MCU receives the working voltage signal 5V, the main control module 14 controls the VDD of the second dimming chip (powered by the auxiliary winding of the constant voltage switching power supply) through the optocoupler U7. For example, when the output LED_EN of the MCU's fifth pin is low, the optocoupler U7 is not turned on, and the second dimming chip does not work without VDD power supply, which reduces standby power consumption. When the output LED_EN of the MCU's fifth pin is high, the optocoupler U7 is turned on, and the second dimming chip starts to work with VDD power supply. That is, both the constant voltage power factor correction unit 123 and the second dimming unit 124 start to work. The MCU then outputs PWM to the second dimming chip, the lighting LED lights up, and PWM dimming can be performed.

[0095] Specifically, such as Figure 15 As shown, the flicker removal unit 127 in this embodiment may include a flicker removal chip, a third low-frequency transformer, a second transistor, a second electrolytic capacitor, a twelfth capacitor, a fourteenth capacitor, a forty-fifth resistor, a forty-seventh resistor, a fiftieth resistor, a fifty-first resistor, and a fifty-second resistor.

[0096] The second terminal of the constant current power factor correction unit 126, the first terminal of the second electrolytic capacitor, and the first terminal of the third low-frequency transformer are electrically connected. The second terminal of the second electrolytic capacitor is electrically connected to the reference ground. The second terminal of the third low-frequency transformer, the first terminal of the second transistor, and the first pin of the anti-flicker chip are electrically connected. The second terminal of the second transistor, the first terminal of the forty-seventh resistor, the first terminal of the fiftieth resistor, the first terminal of the fifty-first resistor, the first terminal of the fifty-second resistor, and the fourth pin of the anti-flicker chip are electrically connected.

The second terminal of the forty-fifth resistor is electrically connected to the fifth pin of the anti-flicker chip. The sixth pin of the anti-flicker chip is electrically connected to the first terminal of the twelfth capacitor. The second terminal of the twelfth capacitor, the first terminal of the fourteenth capacitor, and the second pin of the anti-flicker chip are electrically connected to the reference ground. The second terminal of the fourteenth capacitor is electrically connected to the third pin of the anti-flicker chip.

[0097] In conjunction with the above embodiments, in specific implementation, after the MCU receives the working voltage signal 5V, since the MCU is in the secondary circuit and the dimming IC is in the primary circuit, the main control module 14 controls the VDD of the anti-flicker chip (powered by the auxiliary winding of the constant voltage switching power supply) through the optocoupler U7. For example, when the MCU's fifth pin outputs LED_EN at a low level, the optocoupler U7 is not turned on, and the anti-flicker chip does not work without VDD power supply, which reduces standby power consumption; when the MCU's fifth pin outputs LED_EN at a high level, the optocoupler U7 is turned on, the anti-flicker chip starts to work with VDD power supply, the DIM pin is at a low level for maximum brightness, the MCU outputs PWM to turn on the optocoupler U4, the lighting LED lights up, and PWM dimming can be performed.

[0098] The constant current power factor correction unit 126 can meet harmonic requirements, but its output ripple is large and flickering, which can be harmful to the eyes. To address this, the flicker-eliminating unit 127 detects the output current; when the current decreases and cannot be detected, it stops working. Therefore, the lighting dimming range can meet the 50%-100% requirement. The two units combined achieve high input power factor and high efficiency, with an efficiency greater than 85% for 25W, meeting both harmonic and energy efficiency requirements.

[0099] Furthermore, based on the above embodiments, such as Figure 16As shown, the lighting control module 12 in this embodiment may include a relay 128. One end of the control terminal of the relay 128 serves as the first terminal of the lighting control module 12 and is connected to the first terminal of the power input module 11 for inputting a power signal. The other end of the control terminal of the relay 128 serves as the second terminal of the lighting control module 12 and is electrically connected to the second terminal of the main control module 14 for controlling the energizing state of the coil of the control terminal of the relay 128. The controlled terminal of the relay 128 is connected to the lighting load 15 to control the energizing state of the lighting load 15.

[0100] In this embodiment, relay 128 is used to switch its working state to an on or off state according to the lighting control signal. When relay 128 is in the on state, it outputs a power signal as a second power supply signal to the lighting load 15. That is, one end of the control terminal of relay 128 is connected to the power supply, and the other end is connected to the I / O port of the microcontroller. This is used to control the energization of the control terminal of relay 128, i.e., the coil, so that the moving contact of the controlled terminal of relay 128 connected to the lighting load 15 can be connected to the normally open stationary contact. The normally open stationary contact is connected to the neutral wire or the live wire, and the end of the lighting load 15 not connected to the moving contact is connected to the live wire or the neutral wire. The lighting switch is controlled by relay 128 to connect to the power supply.

[0101] Specifically, such as Figure 17 As shown, the lighting control module 12 in this embodiment may further include a fourth diode, a second transistor, and a thirty-sixth resistor; the first terminal of the lighting load 15 is electrically connected to the live wire, the first terminal of the relay 128 is electrically connected to the lighting load 15, the second terminal of the relay 128 is electrically connected to the first terminal of the power input module 11, specifically, it may be electrically connected to the neutral wire of the power input module 11, the third terminal of the relay 128, the second terminal of the fourth diode, and the first terminal of the main control module 14 are electrically connected, the first terminal of the fourth diode, the first terminal of the second transistor, the fourth terminal of the relay 128, and the second terminal of the main control module 14 are electrically connected, the second terminal of the second transistor is electrically connected to the first terminal of the thirty-sixth resistor, the second terminal of the thirty-sixth resistor is electrically connected to the main control module 14, and the third terminal of the second transistor is electrically connected to the reference ground.

[0102] In conjunction with the above embodiments, in specific implementation, after the MCU receives the 5V operating voltage signal, the main control module 14 controls the second transistor and relay 128 through the optocoupler U7. For example, when the MCU's fifth pin outputs LED_EN at a high level, the second transistor and relay 128 are turned on, and the neutral and live wires at both ends of the lighting load 15 are connected, thus supplying power to the lighting load 15, and the light is on. Conversely, when the MCU's fifth pin outputs LED_EN at a low level, the second transistor and relay 128 are not turned on, stopping the supply of power to the lighting load 15, and the light is off. In this embodiment, the separate lighting driver can improve power efficiency.

[0103] It should be noted that the lighting control module 12 in the aforementioned embodiments can be understood as an independent and parallel implementation scenario, and one or more can be selected for application according to different cost requirements or power output requirements.
