Description

Technical Field

[0001] This utility model pertains to steam ironing technology, specifically relating to a steam iron that operates on dual voltage. Background Technology

[0002] Steam irons rely on steam generated by a vaporization device to iron clothes. The power of a steam iron is primarily reflected in the electrical power of the vaporization device; therefore, the vaporization device must be assigned a rated power during product design and manufacturing. However, actual power conditions vary, such as different regions providing commercial power grids of 220V, 110V, and 100V. When a product is equipped with a fixed-value heating resistor, it is only suitable for operation under the rated voltage to avoid significant differences in output power under different voltage conditions. To ensure the product meets power requirements under different power conditions, a transformer must be installed, leading to inconvenience and high operating costs for users, or complex product structure and high manufacturing costs. Utility Model Content

[0003] This invention addresses the shortcomings of existing steam irons, which use fixed-value heating resistors and require transformers to meet power requirements under different power conditions. This results in inconvenience and high operating costs for users, or complex product structures and high manufacturing costs. The invention provides a steam iron that operates on dual voltage.

[0004] To achieve the above objectives, this utility model discloses a dual-voltage steam iron, comprising a vaporization device for vaporizing water into steam. The vaporization device is characterized by having two heating resistors, which are controlled by a switch to either connect one resistor to the working circuit or both resistors to the working circuit. Thus, power adjustment is achieved by varying the heating resistors connected to the working circuit. This eliminates the need for a transformer, simplifying user operation, reducing operating costs, and reducing product structure and manufacturing costs.

[0005] Preferably, the two heating resistors are connected in parallel when both are connected to the working circuit, in order to reduce the total resistance and adapt to the power supply voltage.

[0006] Preferably, the working circuit provides a first voltage when one heating resistor is connected, and a second voltage when both heating resistors are connected. This allows the product to achieve its power output under different power conditions, and power control of the vaporization device is achieved by providing different voltages. Specifically, the first voltage is greater than the second voltage.

[0007] Preferably, the two heating resistors have different resistance values.

[0008] Preferably, the two heating resistors have different shapes. This is used to efficiently heat the vaporization device.

[0009] Preferably, the vaporization device includes a furnace body with a vaporization chamber having a water inlet and a steam outlet, and two heating resistors embedded in the furnace body to fully utilize the heat from the two heating resistors.

[0010] Preferably, the two heating resistors are stacked in a layered manner. This is used to heat a vaporization device in a three-dimensional space.

[0011] Preferably, the steam iron includes a water pump that supplies water to the vaporization device. Whether one heating resistor is connected to the working circuit or both heating resistors are connected to the working circuit, the water pump is always located in the working circuit, and a start switch is provided for the water pump. Accordingly, the water pump can be started at any time via the start switch, and the water pump supplies water to the vaporization device to generate steam.

[0012] Preferably, when one heating resistor is connected to the working circuit, the working circuit provides a first voltage; when both heating resistors are connected to the working circuit, the working circuit provides a second voltage, and the first voltage is greater than the second voltage. The water pump circuit connects an additional voltage divider resistor in series when the working circuit provides the first voltage compared to when it provides the second voltage. This ensures that the water pump's operating voltage is controlled within its rated voltage range, preventing damage caused by applying excessive voltage to the water pump.

[0013] Preferably, when the working circuit provides the first voltage, the switching switch switches the voltage divider resistor to the water pump circuit; when the working circuit provides the second voltage, the switching switch switches the voltage divider resistor to the water pump circuit. This method of using the same switching switch to simultaneously connect the heating resistor and the water pump to the working circuit is convenient to operate.

[0014] Preferably, a fuse and an electronic thermostat are connected in series in the working circuit, and the electronic thermostat is attached to the surface of the vaporization device.

[0015] This invention equips the vaporization device with two heating resistors, which are controlled by a switch to either connect one or both resistors to the working circuit. Thus, power adjustment is achieved by varying the heating resistors connected to the working circuit. This eliminates the need for a transformer, simplifying user operation, reducing operating costs, and lowering product structure and manufacturing costs.

[0016] This invention provides a first voltage to the working circuit when one heating resistor is connected, and a second voltage when both heating resistors are connected. This allows the product to achieve its power output under different power conditions, and by providing different voltages, the power control of the vaporization device can be realized.

[0017] Regardless of whether one or both heating resistors are connected to the working circuit, the water pump remains within the working circuit, and a start switch is provided for the water pump. Therefore, the water pump can be started at any time via the start switch, and the water pump supplies water to the vaporization device to generate steam.

[0018] This invention provides a first voltage to the working circuit when one heating resistor is connected, and a second voltage when both heating resistors are connected, with the first voltage being greater than the second voltage. The water pump circuit uses an additional voltage divider resistor in series when the working circuit provides the first voltage compared to when it provides the second voltage. This ensures that the water pump's operating voltage is controlled within its rated range, preventing damage caused by excessive voltage applied to the pump.

[0019] This invention allows for convenient operation by using a switch to switch the voltage divider resistor into the water pump circuit when the working circuit provides a first voltage, and to switch it out of the water pump circuit when the working circuit provides a second voltage. This method of simultaneously switching the heating resistor and the water pump into the working circuit using the same switch is easy to implement. Attached Figure Description

[0037] In the description of this utility model, it should be understood that the technical features defined by terms such as "first" and "second" which have a sequential concept are only for the purpose of clearly describing the defined technical features and making the defined technical features clearly distinguishable from other technical features, and do not represent that they are named in this way in actual implementation. Therefore, they should not be construed as limitations on this utility model.

[0038] The present invention will now be described in detail with reference to specific embodiments and accompanying drawings.

[0039] like Figure 8 The image shows a handheld steam iron, which includes a housing and a vaporization device 300 and a water pump 400 disposed within the housing. The housing as a whole includes a head 101 and a handle 102, which can be used to operate the steam iron for ironing.

[0040] This handheld steam iron is suitable for operation under two voltages to accommodate different electrical conditions. It includes a vaporization device 200 for vaporizing water into steam, which is equipped with two heating resistors, one of which is... Figure 3The first heating resistor 201 is shown, and the other is as follows: Figure 4 The second heating resistor 202 is shown. The two heating resistors have different resistance values ​​and shapes to suit the shape of the furnace body and efficiently heat the vaporization device. The two heating resistors are as follows... Figure 1-2 As shown, it is controlled by the switch 300, so that the switch 300, as Figure 1 As shown, the first heating resistor 201 is switched into the working circuit or as... Figure 2 As shown, both the first heating resistor 201 and the second heating resistor 202 are connected to the working circuit. Therefore, power regulation is achieved by varying the heating resistors connected to the working circuit. This eliminates the need for a transformer, simplifying user operation, reducing operating costs, and lowering product structure and manufacturing costs.

[0041] like Figure 1-2 As shown, when both the first heating resistor 201 and the second heating resistor 202 are connected in parallel in the working circuit, they reduce the total resistance and adapt to the supply voltage. When the first heating resistor 201 is connected in the working circuit, the working circuit provides a first voltage; when both the first heating resistor 201 and the second heating resistor 202 are connected in the working circuit, the working circuit provides a second voltage. This allows the product to achieve its power output under different power conditions, and by providing different voltages, the power control of the vaporization device is achieved. Specifically, the first voltage is greater than the second voltage.

[0042] like Figure 5-7 As shown, the vaporization device 200 includes a furnace body 203, which has a vaporization chamber with a water inlet 204 and a steam outlet 205. A first heating resistor 201 and a second heating resistor 202 are both embedded in the furnace body to fully utilize the heat from both resistors. The two heating resistors are stacked in a layered arrangement for heating the vaporization device in a three-dimensional space.

[0043] like Figure 1-2 , Figure 8 As shown, the steam iron includes a water pump 400 that supplies water to the vaporization device. The water pump remains in the operating circuit regardless of whether the first heating resistor 201 is connected to the operating circuit or both the first heating resistor 201 and the second heating resistor 202 are connected. A start switch 401 is provided for the water pump 400. This allows the water pump to be started at appropriate times, supplying water to the vaporization device to generate steam. Furthermore, the operating circuit provides a first voltage when the first heating resistor 201 is connected, and a second voltage when both the first and second heating resistors 201 are connected, with the first voltage being greater than the second voltage. The water pump circuit uses an additional voltage divider resistor 402 connected in series when the operating circuit provides the first voltage compared to when it provides the second voltage. This controls the operating voltage of the water pump within its rated range, preventing damage caused by applying excessive voltage to the pump.

[0044] like Figure 1-2 As shown, when the working circuit provides the first voltage, the switch 300 switches the voltage divider resistor 402 to the water pump circuit; when the working circuit provides the second voltage, the switch 300 switches the voltage divider resistor 402 to the water pump circuit. This method of using the same switch to simultaneously connect the heating resistor and the water pump to the working circuit is convenient to operate.

[0045] like Figure 1-2 As shown, a fuse 500 and an electronic temperature controller 600 are connected in series in the working circuit. Figure 5-6 As shown, the electronic temperature controller is attached to the surface of the vaporization device. In case of overload in the operating circuit, the fuse blows to provide protection. When the vaporization device reaches the set temperature, the electronic temperature controller disconnects, and the first heating resistor and / or the second heating resistor stop heating the vaporization device. If the vaporization device does not reach the set temperature, the electronic temperature controller reconnects the operating circuit, and the first heating resistor and / or the second heating resistor stop continuously heating the vaporization device.

[0046] Taking the first heating resistor 201 with a rated voltage and rated power of 230V / 1300W and the second heating resistor 202 with a rated voltage and rated power of 120V / 750W as an example, if Figure 1 As shown, when the first heating resistor is switched into the working circuit via a switching switch, it outputs 230V / 1300W of power, making it suitable for operation under 230V power conditions. Figure 2 As shown, when both the first and second heating resistors are switched into the working circuit by the switching switch, the first and second heating resistors together output 120V / 1103W of power, which is suitable for working under 120V power conditions.
