Description

Technical Field

[0001] The present application relates to the technical field of garment steamers, and in particular to a voltage-dividing multi-power garment steamer control circuit and a multi-power garment steamer. Background Art

[0002] A garment steamer is a household appliance used for ironing clothes. It produces hot steam or air to help remove wrinkles from clothes and make them look neater.

[0003] The voltage of AC power supply in the world is distributed in two sections: 100V-120V or 220V-240V. For example, Asia, Europe and other regions use 220V AC with a frequency of 50 Hz, while North America, Japan and other regions use 110V AC with a frequency of 60 Hz.

[0004] In today's globalized world, manufacturers need to design garment steamers that can adapt to these two different voltages and improve the applicability of garment steamers in different power supply voltage environments. However, it is obviously inappropriate to design garment steamers with components of different rated working voltages for different power supply voltage environments. This will not only increase the design cost, but also the product is corresponding to one of the power supply voltage environments, and the same garment steamer cannot adapt to two different power supply voltage environments at the same time.

[0028] The present embodiment provides a multi-power supply garment steamer, including a voltage-dividing multi-power supply garment steamer control circuit. The voltage-dividing multi-power supply garment steamer control circuit is built into the multi-power supply garment steamer. The voltage-dividing multi-power supply garment steamer control circuit enables the multi-power supply garment steamer to operate normally under different power supply voltages.

[0029] In order to realize the normal operation of the multi-power garment steamer under different power supply voltages, this embodiment designs a voltage-dividing multi-power garment steamer control circuit. Figure 1 , Figure 1 A schematic diagram of a voltage-dividing multi-power supply garment steamer control circuit provided in an embodiment of the present application.

[0030] In this embodiment, the voltage-dividing multi-power garment steamer control circuit includes a power switch 12, a heating unit 13, a water supply unit 14, and a voltage regulating circuit 15. The power switch 12 is connected to the heating unit 13 and the water supply unit 14, and the heating unit 13 and the water supply unit 14 are connected to the voltage regulating circuit 15 to form a voltage-dividing multi-power garment steamer control circuit, which is connected to both ends of the power supply, wherein the voltage regulating circuit is used to adjust the input voltage of different voltage environments to a voltage that enables the multi-power garment steamer to work normally.

[0031] In this embodiment, the multi-power supply garment steamer control circuit based on automatic voltage division may further include a power connector 11, and the power connector 11 connecting two ends of a power supply is used as an example for description.

[0032] The power connector 11 includes a first contact piece (i.e., a contact point connected to the power supply) and a second contact piece (another contact point connected to the power supply): the first contact piece is connected in series with the power switch 12, and then connected to the parallel heating part 13 and the water supply part 14, and then connected to the voltage regulating circuit 15, and then returned to the second contact piece to form a voltage-dividing multi-power supply garment steamer control circuit. The voltage regulating circuit 15 is used to form different control loops based on the user's operation of the working voltage selection switch 152, so as to realize the normal operation of the multi-power supply garment steamer under different power supply voltages.

[0033] In order to ensure the safety of the heating part 13, the heating part 13 may include a heating element 131 and a temperature fuse 132 connected in series. The temperature fuse 132 may be fused when the heating part 13 is overheated, thereby protecting the multi-power supply garment steamer.

[0034] In order to maintain a certain temperature level when the multi-power garment steamer is working, the heating part 13 also includes a thermostat 133. The thermostat 133 is connected in series with the heating element 131 and the temperature fuse 132 to achieve temperature control.

[0035] The water supply unit 14 may include a diode 141 and a water pump 142 . The diode 141 and the water pump 142 (pulse pump) of the water supply unit are connected in series. The diode 141 allows half a cycle of the alternating current (sine wave) to pass through to power the water pump 142 and ensure the normal operation of the water pump 142 .

[0036] In this embodiment, the voltage regulating circuit 15 includes a parallel working voltage selection switch 152 and a voltage dividing resistor 151. When the working voltage selection switch 152 is disconnected, the voltage dividing resistor 151 is normally connected to the voltage dividing multi-power supply garment steamer control circuit to divide the voltage; when the working voltage selection switch 152 is closed, the voltage dividing resistor 151 is short-circuited, not connected to the voltage dividing multi-power supply garment steamer control circuit, and no voltage division is performed. The voltage division here means that the voltage dividing resistor is connected in series to the circuit, so that the voltage in the circuit is distributed according to the resistance value, thereby obtaining a part of the voltage and reducing the voltage of other parts in the series circuit.

[0037] Then, based on the user's manual operation of the working voltage selection switch 152, when the working voltage selection switch 152 is disconnected, the voltage dividing resistor 151 is normally connected to the voltage dividing multi-power supply garment steamer control circuit to perform voltage division, thereby achieving normal operation under a high power supply voltage environment (for example, 200-240V); when the working voltage selection switch 152 is closed, the voltage dividing resistor 151 is short-circuited, and is not connected to the voltage dividing multi-power supply garment steamer control circuit, and no voltage division is performed, thereby achieving low power supply voltage operation (for example, 100-120V). In this way, components that can meet the normal operation under a 120V power supply voltage (such as a water pump 142, a heating element 131, etc.) can be selected, and they can work normally under different power supply voltage conditions.

[0038] The impedance of the voltage dividing resistor 151 satisfies the following relationship:

[0039]

[0040] Among them, Z vd represents the impedance of the voltage divider resistor 151, Z f represents the impedance of the heat generating unit 13, Z w represents the impedance of the water supply unit 14, and the value range of a is [0.9, 1.1].

[0041] In this embodiment, taking a=1 as an example (i.e., the impedance of the voltage-dividing resistor 151 is equal to the overall impedance of the heating part 13 and the water supply part 14), it can play a precise voltage-dividing role. After connecting to the mains (e.g., 220V), the voltage is divided by the voltage-dividing resistor 151, so that the voltage distributed to the water supply part 14 and the heating part 13 is 110V (the two are connected in parallel), and the voltage-dividing resistor 151 is also distributed to the 110V voltage.

[0042] In summary, the embodiment of the present application provides a voltage-dividing multi-power supply garment steamer control circuit and a multi-power supply garment steamer. After the power switch 12 is connected in series through the first contact piece of the power connector 11, the parallel heating part 13 and the water supply part 14 are connected, and then connected to the voltage regulating circuit 15, and then returned to the second contact piece to form a voltage-dividing multi-power supply garment steamer control circuit. The voltage regulating circuit 15 is used to form different control loops based on the user's operation of the working voltage selection switch 152, so as to realize the normal operation of the multi-power supply garment steamer under different power supply voltages. The heating part 13 includes a heating element 131 and a temperature fuse 132 connected in series. The temperature fuse 132 can be blown when overheated to protect the multi-power supply garment steamer, and the heating part 13 can also include a thermostat 133 to control the temperature of the heating element 131 to maintain a relatively stable level. The diode 141 of the water supply part 14 and the water pump 142 (pulse pump) are connected in series. The diode 141 allows half a cycle of the alternating current (sine wave) to pass through, powering the water pump 142 and ensuring the normal operation of the water pump 142. The voltage regulating circuit 15 includes a parallel working voltage selection switch 152 and a voltage dividing resistor 151. Based on the manual operation of the working voltage selection switch 152 by the user, when the working voltage selection switch 152 is disconnected, the voltage dividing resistor 151 is normally connected to the voltage dividing multi-power supply garment steamer control circuit to divide the voltage, thereby achieving normal operation in a high power supply voltage environment (e.g., 200-240V); when the working voltage selection switch 152 is closed, the voltage dividing resistor 151 is short-circuited, not connected to the voltage dividing multi-power supply garment steamer control circuit, and does not divide the voltage, thereby achieving low power supply voltage operation (e.g., 100-120V). In this way, components that can meet the normal operation under a 120V power supply voltage can be selected, and they can work normally under different power supply voltage conditions. The impedance selection of the voltage dividing resistor 151 can be determined according to the impedance of the load, thereby achieving accurate voltage division and controlling the working voltage of the multi-power supply garment steamer.

[0043] The above description is only an embodiment of the present application and is not intended to limit the protection scope of the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
