Detailed Implementation

[0019] In related technologies, during long-term use of ironing machines, minerals in the water can easily form scale deposits on the surface of the heating element, affecting the evaporation efficiency of the water, resulting in a gradual decrease in the amount of steam, and even dripping or spraying of water, which wets the fabric being ironed, affecting the user experience and ironing effect.

[0020] To address the aforementioned issues, this utility model provides a steam generator and an ironing device. By placing the heating element above the vaporization chamber and constructing a steam outlet column structure on the base plate that extends above the bottom of the chamber, scale is deposited in the non-heating area, effectively avoiding the impact of scale on heating efficiency, reducing dripping and spraying, improving steam generation efficiency and safety, and ultimately enhancing the user experience and ironing effect.

[0026] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0027] The following describes in detail the overall structure, working principle, and technical effects of the steam generator provided by this utility model through embodiments and in conjunction with the accompanying drawings.

[0028] Please see Figures 1 to 5 This utility model provides a steam generator 10 for use in ironing equipment, which effectively avoids the impact of limescale on heating efficiency, reduces dripping and spraying, improves steam generation efficiency and safety, and thus improves user experience and ironing effect. The steam generator 10 includes a heating element 100 and an ironing element 300.

[0029] The ironing assembly 300 includes a base plate 310 and a surrounding plate 330. The surrounding plate 330 forms a vaporization chamber 320 around the base plate 310, and the opening end of the vaporization chamber 320 cooperates with the heating assembly 100 so that the heat generated by the heating assembly 100 can be effectively conducted into the vaporization chamber 320 to heat the water entering it into steam.

[0030] Based on the above, the base plate 310 extends upward to form a steam column 311, which is located inside the vaporization chamber 320 and is provided with a steam outlet 313. The steam outlet 313 is used to connect the inside of the vaporization chamber 320 with the external environment so as to discharge the generated steam for ironing.

[0031] Based on the above structural configuration, this invention, by placing the heating element 100 above the vaporization chamber 320, ensures that scale mainly deposits in the non-heating area at the bottom of the vaporization chamber 320, thereby effectively preventing scale from covering the heating surface and affecting heat exchange efficiency. Simultaneously, the steam outlet column 311, extending above the bottom of the vaporization chamber 320, is provided on the base plate 310 to prevent scale from clogging the steam outlet 313, ensuring smooth steam discharge and further improving the stability and service life of the device.

[0032] Optionally, the ironing component 300 is made of aluminum, which has good thermal conductivity, facilitating rapid heat conduction and uniform distribution, thereby improving steam generation efficiency and ironing effect. For water that is not fully vaporized, it will flow to one side of the soleplate 310 under gravity, absorbing heat conducted by the soleplate 310 during the flow to achieve secondary evaporation, thus reducing residual water and further improving steam conversion rate and thermal energy utilization rate.

[0033] In addition, it should be noted that the flow rate of water or water vapor entering the vaporization chamber 320 is matched with the heating power of the steam generator 10 through a water pump or other control methods, so that the water supply is in correspondence with the power of the heating element 100, which conforms to the principle of energy conservation. This avoids excessive water residue in the vaporization chamber 320, ensures that the water can be fully vaporized, and improves the stability of steam output and the overall working efficiency of the device.

[0034] In an optional embodiment, the height of the steam outlet column 311 is not less than 2 mm. Based on this configuration, on the one hand, it effectively prevents scale particles from entering the steam outlet hole 313 and causing blockage, ensuring smooth steam discharge; on the other hand, incompletely vaporized water droplets fall back to the area below the steam outlet column 311 under gravity, thereby further reducing the possibility of liquid water spraying out of the steam outlet hole 313 and lowering the probability of dripping or spraying. In specific applications, the above height can be adaptively adjusted according to lifespan requirements.

[0035] Furthermore, the diameter of the steam outlet 313 is not less than 1.5 mm. By setting the steam outlet 313 to this size range, the flow area for steam discharge can be guaranteed, the steam flow resistance can be reduced, thereby accelerating the steam output speed and improving the steam generation efficiency.

[0036] like Figure 1 and Figure 2 As shown, the heating assembly 100 includes a heating plate 110 and a temperature control device 130, both for electrical connection to a circuit board. The heating plate 110 mates with and connects to the opening of the vaporization chamber 320, generating heat when energized to provide the necessary thermal energy for steam generation. The temperature control device 130 is connected in series with the heating plate 110 and trips when the heating plate 110 exceeds a preset temperature, stopping the heating plate 110 from operating and thus achieving temperature control of the heating assembly 100.

[0037] It is understandable that the preset temperature can refer to either the protection temperature, used to protect the heating element 100 from overheating and prevent the heating plate 110 from burning out or causing other safety hazards due to excessive temperature; or it can refer to the maximum operating temperature of the heating element 100, used to ensure that it operates within a safe temperature range and extend its service life.

[0038] In some embodiments, the temperature control device 130 may be a manually reset type temperature controller, whose maximum set protection temperature does not exceed 240°C; in other embodiments, the temperature control device 130 may also be a temperature fuse. No specific limitations are made in this embodiment.

[0039] In addition, the heating element 100 also includes a thermistor 150 for connection to the circuit board. The thermistor 150 is disposed on the heating plate 110 and serves as a temperature sensing element to acquire the temperature information of the heating plate 110 in real time and feed the temperature signal back to the control chip on the circuit board. Through this feedback signal, the control system can dynamically adjust the temperature of the heating plate 110 in real time to keep it within the set range, thereby achieving precise temperature control and improving the operational stability and safety of the steam generator 10.

[0040] In some embodiments, a heating film is provided on the surface of the heating plate 110. This heating film can rapidly generate heat when energized, achieving rapid temperature rise and providing an efficient and stable heat source for steam generation. In other alternative embodiments, a resistance wire structure can also be provided on the heating plate 110 as a heating element, which can also achieve water heating and steam generation. Both of these heating methods can be selected according to actual needs and can effectively meet the usage requirements of the steam generator 10.

[0041] Based on the above configuration, it should be noted that the heating plate 110 in this invention has a high power density, achieving a power output of up to 60W per unit area (per square centimeter), significantly higher than the approximately 25W power density of traditional tubular heating elements. At the same power output, this structure is smaller and lighter, effectively reducing the overall weight of the device and making it easier and less strenuous for users to operate, reducing hand fatigue. Furthermore, compared to traditional tubular heating elements, the heating plate 110 increases heating speed by more than 50%, significantly shortening preheating time.

[0042] Furthermore, such as Figure 3 As shown, the heating element 100 also includes a heat sink 170. One side of the heat sink 170 is engaged and connected to the opening end of the vaporization chamber 320, and the other side is attached to the heating element 110. Furthermore, a water inlet pipe 171 extends upward from the heat sink 170, passes through the heating element 110, and communicates with the vaporization chamber 320 to introduce external water into the vaporization chamber 320 so that it can be rapidly converted into steam during the heating process.

[0043] To further enhance the heat exchange capacity within the vaporization chamber 320, heat dissipation fins are provided on the side of the heat dissipation plate 170 that mates with the opening of the vaporization chamber 320. Based on this structural design, when water or a water-vapor mixture enters the vaporization chamber 320, it can fully contact the heat dissipation fins and rapidly absorb heat through the fins, efficiently converting it into steam. Optionally, multiple heat dissipation fins are provided and arranged regularly along the surface of the heat dissipation plate 170 to increase the heat dissipation area and improve the heat transfer efficiency and uniformity of heat dissipation.

[0044] It should also be noted that, in the embodiments provided in this application, the heating plate 110 has a thickness of 1mm to 4mm and is made of stainless steel, possessing good high-temperature resistance and structural strength; the heat sink 170 also has a thickness of 1mm to 4mm and is made of aluminum or other materials with a higher thermal conductivity than stainless steel to improve heat transfer efficiency. Furthermore, in other alternative embodiments, the heating plate 110 and the heat sink 170 can be integrally formed, i.e., the separate heating plate 110 substrate is omitted, and the heating film is directly disposed on the heat sink 170.

[0045] Furthermore, the heating component 100 also includes a heat-conducting layer 190, which is disposed between the heating plate 110 and the heat sink 170 to fill the gap between them, thereby achieving full coverage of the thermal contact surface and effectively improving the heat transfer efficiency.

[0046] Specifically, the thermally conductive layer 190 includes a graphite layer. Graphite material has excellent lateral thermal conductivity, which can quickly conduct heat from the local high-temperature area of ​​the heating plate 110 to the heat dissipation fins, enabling the heat dissipation fins to exchange heat more efficiently with the water or water vapor in the vaporization chamber 320. This avoids the risk of damage to the heating film due to local overheating and improves the stability and service life of the heating component 100.

[0047] Optionally, the thickness of the graphite layer ranges from 0.5 mm to 3 mm, which ensures good thermal conductivity while maintaining a compact overall design.

[0048] Furthermore, it should be noted that multiple fasteners (such as screws) can sequentially pass through the heating plate 110, the heat-conducting layer 190, and the heat dissipation plate 170, and be fixedly connected to the fixing holes on the enclosure 330, as detailed below. Figure 1 As shown.

[0049] In summary, this utility model provides a steam generating device 10, including a heating element 100 and an ironing element 300. The ironing element 300 is formed by a base plate 310 and a surrounding plate 330, creating a vaporization chamber 320. Its open end cooperates with the heating element 100 to achieve heat conduction. The base plate 310 is provided with a steam outlet column 311 located within the vaporization chamber 320, and the steam outlet column 311 is provided with a steam outlet hole 313 for connecting the chamber to the outside. It can be understood that by placing the heating element 100 above the vaporization chamber 320 and using a steam outlet column 311 structure that extends above the bottom of the chamber, scale is deposited in the non-heating area, effectively avoiding its impact on heating efficiency, reducing dripping and spraying phenomena, improving steam generation efficiency and safety, thereby improving the user experience and ironing effect.

[0050] In addition, this utility model also provides an ironing device, such as a garment steamer or iron, which includes a water pipe and the steam generating device 10 in the aforementioned embodiment. The water pipe and the steam generating device 10 are connected to each other for supplying external water to the vaporization chamber 320 of the steam generating device 10, so that it is converted into steam under heating and used for ironing. By adopting the aforementioned steam generating device 10, this ironing device can effectively improve steam generation efficiency, reduce the impact of scale on the heating element 100, improve the stability and service life of the device, and improve the user experience. The relevant structure and technical effects have been described in detail above and will not be repeated here.

[0051] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
