Description

Technical Field

[0001] This application relates to the field of ironing equipment technology, and more particularly to a steam generator and ironing equipment. Background Technology

[0002] The main function of steam equipment (such as handheld steam brushes, irons, etc.) is to heat water in a boiler through electric heating tubes to generate high-temperature steam for cleaning, ironing and other purposes.

[0003] In existing technologies, the higher the power of steam equipment, the stronger the steam output and pressure. However, increased power leads to greater temperature fluctuations in the boiler. Specifically, the boiler typically uses a thermostat (such as a KSD temperature control switch) to control the power supply to the heating element. Power is cut off when the temperature reaches a first set value, and re-energized when the temperature drops to a second set value, creating temperature peaks and troughs. At high temperatures, the steam output is large and the pressure is high; at low temperatures, the steam output drops sharply and the pressure weakens, causing users to perceive fluctuating steam levels. Utility Model Content

[0004] Based on this, this application provides a steam generator and an ironing device to address the shortcomings of related technologies.

[0005] In a first aspect, this application provides a steam generator, comprising:

[0006] The first heating component includes a first heating element and a first temperature control element, wherein a first end of the first heating element is electrically connected to a second end of the first temperature control element.

[0007] The second heating element includes a second heating element, a second fuse, and a second temperature control. The first end of the second heating element is electrically connected to the second end of the second temperature control.

[0008] The second end of the first heating element is electrically connected to the second end of the second heating element, and the first end of the first temperature control element is electrically connected to the first end of the second temperature control element.

[0009] The power-off temperature of the first temperature control is lower than that of the second temperature control.

[0010] The steam generator provided in this application embodiment uses a first heating element and a second heating element to heat liquid water into high-temperature steam. A first temperature control element controls the energizing and de-energizing of the first heating element, and a second temperature control element controls the energizing and de-energizing of the second heating element. Since the de-energizing temperature of the first temperature control element is lower than that of the second temperature control element, when the first temperature control element is de-energized, the second temperature control element is energized. This allows the second heating element to continue heating, maintaining the temperature and pressure of the steam generator, thereby reducing temperature fluctuations and ensuring a stable steam output.

[0011] In one possible implementation, the power of the first heating element is greater than the power of the second heating element.

[0012] Thus, during initial heating, the first and second heating elements work together at a high power, allowing the steam generator to reach the vaporization temperature quickly. Afterward, the first heating element is de-energized, and the second heating element maintains a continuous and stable output of steam at a lower power. Furthermore, the steam generator continuously replenishes water during operation. Due to the lower power of the second heating element, the heat generated by it can be absorbed by the liquid water, making it difficult for the temperature of the second temperature control to reach its de-energization temperature, thereby ensuring that the second heating element continues to heat up.

[0013] In one possible implementation, the first heating component further includes a first fuse, the first end of which is electrically connected to the second end of the first heating component;

[0014] The second heating element also includes a second fuse, the first end of which is electrically connected to the second end of the second heating element, and the second end of the first fuse is electrically connected to the second end of the second fuse.

[0015] Thus, the first fuse, the first heating element, and the first temperature control element are connected in series to form the first heating circuit. The first fuse can provide overcurrent and short-circuit protection for the first heating circuit. The second fuse, the second heating element, and the second temperature control element are connected in series to form the second heating circuit. The second fuse can provide overcurrent and short-circuit protection for the second heating circuit.

[0016] In one possible implementation, the steam generator further includes a housing, and both the first heating element and the second heating element are disposed within the housing;

[0017] The shell has a steam chamber and a water inlet that are interconnected. The first heating element and the second heating element are located on one side of the steam chamber, and the water inlet and the first heating element are located on opposite sides of the steam chamber.

[0018] Along the direction in which the water inlet and the first heating element are positioned, the projection of the first heating element on the housing at least partially overlaps with the projection of the water inlet on the housing.

[0019] In this way, the water inlet can be positioned to correspond with the first heating element with higher power, thereby aligning the water inlet with the part of the steam chamber with higher temperature. This allows the liquid water to be immediately vaporized at high temperature as it enters the steam chamber through the water inlet, thus forming high-temperature steam.

[0020] In one possible implementation, the first heating element includes a first heating segment and two second heating segments, the two second heating segments being connected to both ends of the first heating segment, both the first heating segment and the second heating segment extending along an arc, and the bending directions of the first heating segment and the second heating segment being opposite;

[0021] The projection of the first heating section on the shell at least partially overlaps with the projection of the water inlet on the shell.

[0022] Thus, by setting the first heating element as multiple curved heating sections, the length of the first heating element can be extended within the limited steam chamber space, thereby enabling the first heating element to have greater power. Furthermore, the water inlet corresponds to the higher-temperature first heating section, allowing the first heating section to quickly replenish the heat lost at the water inlet, thus enabling the liquid water entering the steam chamber from the water inlet to be rapidly heated and vaporized. In one possible implementation, the shell also has a steam outlet communicating with the steam chamber, with the steam outlet and the water inlet located on adjacent sides of the steam chamber.

[0023] The first heating element is arranged around the outer periphery of the second heating element, and the first heating element is positioned closer to the steam outlet than the second heating element.

[0024] This allows for a larger first heating element, enabling it to heat the liquid water or air within the steam chamber with greater power. Once the liquid water transforms into steam, the steam can be ejected from the steam outlet, allowing for the ironing and cleaning of fabrics.

[0025] In one possible implementation, the steam chamber includes two flow channels arranged in a meandering manner. The beginnings of the two flow channels converge at the water inlet, and the ends of the two flow channels are connected to the steam outlet.

[0026] In this way, after liquid water enters the steam chamber from the inlet, it can be diverted to two channels, so that the liquid water is heated and vaporized as it flows along the extension direction of the channel, or the steam is vaporized more completely and fully as it flows along the extension direction of the channel, and then sprayed out from multiple steam outlets.

[0027] In one possible implementation, the first heating element further includes two third heating segments, both of which extend along a straight line and are arranged in parallel. The third heating segments correspond one-to-one with the second heating segments and are connected to the end of the second heating segment away from the first heating segment.

[0028] The second heating element includes a fourth heating section and two fifth heating sections. The two fifth heating sections are connected to both ends of the fourth heating section and are arranged in parallel.

[0029] Thus, the first heating element can be an electric heating tube bent into a shape similar to an M, and the second heating element can be an electric heating tube bent into a shape similar to a U. The first and second heating elements can fill the steam chamber, thereby evenly heating the liquid water or air in various parts of the steam chamber, resulting in more uniform steam production. Secondly, this application provides an ironing device, comprising:

[0030] The steam generator provided in the first aspect above;

[0031] The equipment body, and the steam generator are connected to the equipment body.

[0032] In one possible implementation, the device body includes a control component, a drive pump, and a water tank, and the steam generator includes a first heating component, a second heating component, and a housing;

[0033] The first heating element, the second heating element, and the drive pump are all electrically connected to the control component;

[0034] The water tank is configured to store liquid, and both the housing and the water tank are connected to a drive pump, which is configured to drive the liquid from the water tank into the housing.

[0035] Thus, when the temperature of the steam chamber reaches the vaporization temperature, the control component controls the drive pump to drive the liquid water in the water tank into the steam chamber, thereby causing the liquid water to vaporize into steam. Throughout the entire operation, the control component can control the drive pump to continuously replenish water to the steam chamber, and the control component can also be used to control the first heating component and the second heating component.

Detailed Implementation

[0052] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The described embodiments are some, but not all, embodiments of this application. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0053] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0054] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0055] The terms "first," "second," and "third" (if any) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein.

[0056] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or display that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or display.

[0057] In existing technologies, the higher the power of steam equipment, the stronger the steam output and pressure. However, increased power leads to greater temperature fluctuations in the boiler. Specifically, the boiler typically uses a thermostat (such as a KSD temperature control switch) to control the power supply to the heating element. Power is cut off when the temperature reaches a first set value, and re-energized when the temperature drops to a second set value, creating temperature peaks and troughs. At high temperatures, the steam output is large and the pressure is high; at low temperatures, the steam output drops sharply and the pressure weakens, causing users to perceive fluctuating steam levels.

[0058] In view of the above problems, this application provides a steam generator and an ironing device. Since the power-off temperature of the first temperature control is lower than that of the second temperature control, when heating begins, the first heating element and the second heating element heat up together, and the steam generator operates at a higher power, thereby reducing the initial waiting time. When the first heating element and the second heating element heat up until the first temperature control reaches its power-off temperature, the first temperature control is disconnected, thereby controlling the first heating element to stop heating. The power-off temperature of the second temperature control is higher, and the second heating element can continue to heat up, thereby reducing the temperature fluctuation range of the steam generator and extending the power-on and power-off time of the first heating element, thereby extending the time difference between the temperature peak and the temperature trough, so that the steam can maintain a stable output for a long time.

[0059] The following is in conjunction with the appendix Figures 1 to 12 The specific methods of the steam generator and ironing equipment provided in the embodiments of this application will be described in detail.

[0060] Reference Figures 1 to 10 As shown, the steam generator 10 provided in this embodiment includes a first heating element 100 and a second heating element 200. The first heating element 100 includes a first heating element 110 and a first temperature control element 120. The first end of the first heating element 110 is electrically connected to the second end of the first temperature control element 120. The second heating element 200 includes a second heating element 210, a second fuse 230, and a second temperature control element 220. The first end of the second heating element 210 is electrically connected to the second end of the second temperature control element 220. The second end of the first heating element 110 is electrically connected to the second end of the second heating element 210, and the first end of the first temperature control element 120 is electrically connected to the first end of the second temperature control element 220.

[0061] The power-off temperature of the first temperature control 120 is lower than that of the second temperature control 220.

[0062] The steam generator 10 provided in this application embodiment can be used in ironing equipment such as handheld steam brushes and ironing machines to provide high-temperature steam for cleaning and ironing fabrics.

[0063] Specifically, both the first heating element 110 and the second heating element 210 are used for heating, so that after the liquid water enters the steam generator 10, it is converted into steam under high temperature. The power of the first heating element 110 and the power of the second heating element 210 can be equal, or the power of the first heating element 110 can be greater than the power of the second heating element 210, or the power of the first heating element 110 can be less than the power of the second heating element 210.

[0064] The first temperature control 120 is used to control the power-on and power-off state of the first heating element 110, and the second temperature control 220 is used to control the power-on and power-off state of the second heating element 210.

[0065] In other words, the first temperature control 120 can sense the temperature of the first heating element 110, and when the temperature of the first temperature control 120 reaches its power-off temperature, the first temperature control 120 is powered off, thereby causing the first heating element 110 to stop heating, until the first temperature control 120 reaches its power-on temperature, at which point the first temperature control 120 is powered on, thereby causing the first heating element 110 to reheat.

[0066] Similarly, the second temperature control 220 can sense the temperature of the second heating element 210, and when the temperature of the second temperature control 220 reaches its power-off temperature, the second temperature control 220 is powered off, thereby causing the second heating element 210 to stop heating, until the second temperature control 220 reaches its power-on temperature, at which point the second temperature control 220 is powered on, thereby causing the second heating element 210 to reheat.

[0067] In this circuit, the first heating element 110 and the first temperature control element 120 are connected in series to form a first heating circuit, and the second heating element 210 and the second temperature control element 220 are connected in series to form a second heating circuit. The first heating circuit and the second heating circuit are connected in parallel, thus forming a... Figure 7 The equivalent circuit shown.

[0068] Since the de-energizing temperature of the first temperature control 120 is lower than that of the second temperature control 220, when the steam generator 10 is initially started to heat, the temperatures of both the first temperature control 120 and the second temperature control 220 are low and have not yet reached their de-energizing temperatures. Therefore, the first heating element 110 and the second heating element 210 can heat together, thereby enabling the steam generator 10 to have a larger heating power, which in turn can shorten the initial steam output time and reduce the user's waiting time.

[0069] After heating for a period of time, the temperature of the steam generator 10 rises. When the temperature of the first temperature control 120 reaches its power-off temperature, the first temperature control 120 is de-energized, thereby disconnecting the first heating circuit and causing the first heating element 110 to stop heating, thus preventing the steam generator 10 from being damaged by continuous heating.

[0070] At this time, the temperature of the second temperature control 220 has not reached its de-energization temperature, so the second temperature control 220 is energized, the second heating circuit is open, and the second heating element 210 continues to heat to maintain the temperature and pressure of the steam generator 10, thereby maintaining the output of steam at a relatively high intensity. Until the temperature of the first temperature control 120 reaches its energization temperature, the first temperature control 120 is re-energized, thereby causing the first heating element 110 to reheat together with the second heating element 210.

[0071] Throughout the process, since the second heating element 210 can continuously heat, the temperature and pressure of the steam generator 10 can be prevented from dropping sharply due to the power failure of the first heating element 110. The temperature change is relatively stable, thus maintaining a stable output of steam. Furthermore, the power-on and power-off time of the first heating element 110 can be extended, thereby extending the time difference between the peak temperature and the trough temperature of the steam generator 10.

[0072] The steam generator 10 provided in this embodiment includes a first heating element 100 and a second heating element 200. The first heating element 100 includes a first heating element 110 and a first temperature control 120. The second heating element 200 includes a second heating element 210 and a second temperature control 220. The first heating element 110 and the second heating element 210 are used for heating to convert liquid water into high-temperature steam. The first temperature control 120 is used to control the energization / de-energization of the first heating element 110, and the second temperature control 220 is used to control the energization / de-energization of the second heating element 210. Since the de-energization temperature of the first temperature control 120 is lower than that of the second temperature control 220, when the first temperature control 120 is de-energized, the second temperature control 220 is energized, allowing the second heating element 210 to continue heating, maintaining the temperature and pressure of the steam generator 10. This reduces temperature fluctuations in the steam generator 10, thus ensuring a stable steam output.

[0073] In some embodiments, the power of the first heating element 110 is greater than the power of the second heating element 210.

[0074] It is understandable that, since the first heating element 110 and the second heating element 210 are connected in parallel, the heating power of the steam generator 10 is the sum of the power of the first heating element 110 and the power of the second heating element 210.

[0075] Thus, during initial heating, the first heating element 110 and the second heating element 210 heat together with a relatively high power, enabling the steam generator 10 to reach the vaporization temperature quickly. Afterward, the first heating element 110 is de-energized, and the second heating element 210 maintains a continuous and stable output of steam with a relatively low power. Furthermore, the steam generator 10 continuously replenishes water during operation. Due to the low power of the second heating element 210, the heat generated by the second heating element 210 can be absorbed by the liquid water, making it difficult for the temperature of the second temperature control unit 220 to reach its de-energization temperature, thereby allowing the second heating element 210 to continue heating.

[0076] For example, the power-off temperature of the first temperature control unit 120 can be set to 135℃, the power of the first heating element 110 can be set to 1200W, the power-off temperature of the second temperature control unit 220 can be set to 170℃, and the power of the first heating element 110 can be set to 300W. During the initial period after the steam generator 10 is powered on, the first heating element 110 and the second heating element 210 heat together at a power of 1500W. When the steam generator 10 stabilizes, the temperature of the first temperature control unit 120 reaches 135℃, the first temperature control unit 120 is powered off, the first heating element 110 stops heating, and the second heating element 210 continues to heat at a power of 300W.

[0077] Reference Figure 6 and Figure 10 As shown, in one possible implementation, the first heating component 100 further includes a first fuse 130, the first end of which is electrically connected to the second end of the first heating component 110. The second heating component 200 further includes a second fuse 230, the first end of which is electrically connected to the second end of the second heating component 210, and the second end of the first fuse 130 is electrically connected to the second end of the second fuse 230.

[0078] With this configuration, the first fuse 130, the first heating element 110, and the first temperature control element 120 are connected in series to form a first heating circuit. The first fuse 130 can provide overcurrent and short-circuit protection for the first heating circuit. The second fuse 230, the second heating element 210, and the second temperature control element 220 are connected in series to form a second heating circuit. The second fuse 230 can provide overcurrent and short-circuit protection for the second heating circuit. The first heating circuit and the second heating circuit can be connected in parallel to form a... Figure 7 The equivalent circuit shown.

[0079] Among them, reference Figure 6 As shown, the first heating component 100 may further include a first mounting member 140, and the first safety member 130 may be connected to the housing 300 through the first mounting member 140. The second heating component 200 may further include a second mounting member 240, and the second safety member 230 may be connected to the housing 300 through the second mounting member 240.

[0080] Reference Figure 1 , Figure 8 , Figure 9 As shown, in one possible implementation, the steam generator 10 further includes a housing 300, and the first heating element 110 and the second heating element 210 are both disposed within the housing 300. The housing 300 has a steam chamber 310 and a water inlet 320 that communicate with each other. The first heating element 110 and the second heating element 210 are located on one side of the steam chamber 310, and the water inlet 320 and the first heating element 110 are located on opposite sides of the steam chamber 310.

[0081] Along the direction of the water inlet 320 and the first heating element 110 (e.g.) Figure 5 The inlet 320 and the first heating element 110 are arranged in the vertical direction. The projection of the first heating element 110 on the housing 300 at least partially overlaps with the projection of the inlet 320 on the housing 300.

[0082] For example, the housing 300 may be provided with a first mounting groove and a second mounting groove, both of which are connected to the steam chamber 310. The first heating element 110 is disposed in the mounting groove, and the second heating element 210 is disposed in the second mounting groove. Both the first heating element 110 and the second heating element 210 can heat the steam chamber 310, thereby creating a high-temperature and high-pressure environment inside the steam chamber 310.

[0083] Since the first heating element 110 and the second heating element 210 are located on both sides of the water inlet 320 in the steam chamber 310, and the water inlet 320 is corresponding to the first heating element 110 with higher power, the water inlet 320 corresponds to the part of the steam chamber 310 with higher temperature, so that the liquid water can be immediately vaporized at high temperature when it enters the steam chamber 310 from the water inlet 320, thereby forming high temperature steam.

[0084] Among them, reference Figure 4 and Figure 6 As shown, for ease of processing and assembly, the housing 300 may include a main housing 300a and a cover plate 300b. The main housing 300a and the cover plate 300b are connected to jointly define the steam chamber 310. The water inlet 320 is provided on the cover plate 300b. The first heating element 100 and the second heating element 200 are both connected to the main housing 300a.

[0085] Reference Figures 2 to 6 As shown, in some embodiments, the steam generator 10 may further include a water inlet connector 400 and a first seal 500. The water inlet connector 400 is located at the water inlet 320 to communicate with the water tank 40 through a pipe. The first seal 500 is located between the water inlet 320 and the water inlet connector 400 to prevent leakage of liquid water or steam.

[0086] Reference Figure 6 As shown, in some embodiments, the first heating element 110 includes a first heating segment 111 and two second heating segments 112, which are connected to both ends of the first heating segment 111. Both the first heating segment 111 and the second heating segment 112 extend along an arc, and their bending directions are opposite. The projection of the first heating segment 111 on the housing 300 at least partially coincides with the projection of the water inlet 320 on the housing 300.

[0087] In this way, by setting the first heating element 110 as multiple curved heating sections, the length of the first heating element 110 can be extended within the limited space of the steam chamber 310, thereby enabling the first heating element 110 to have greater power. Furthermore, the water inlet 320 corresponds to the first heating section 111 with a higher temperature, so that the first heating section 111 can quickly replenish the heat lost at the water inlet 320, thereby enabling the liquid water entering the steam chamber 310 from the water inlet 320 to be rapidly heated and vaporized.

[0088] Reference Figure 9 and Figure 11 As shown, in some embodiments, the housing 300 further has a steam outlet 330 communicating with the steam chamber 310, and the steam outlet 330 and the water inlet 320 are located on adjacent sides of the steam chamber 310. The first heating element 110 surrounds the outer periphery of the second heating element 210, and the first heating element 110 is disposed close to the steam outlet 330 relative to the second heating element 210.

[0089] This configuration allows for a larger volume of the first heating element 110, enabling it to heat the liquid water or air within the steam chamber 310 with greater power. Once the liquid water is converted into steam, the steam can be ejected from the steam outlet 330, allowing for the ironing and cleaning of fabrics. Furthermore, the closer proximity of the first heating element 110 to the steam outlet 330 facilitates the thorough vaporization of the liquid water before its ejection.

[0090] Reference Figures 2 to 6 As shown, in some embodiments, the steam generator 10 may further include a steam panel 600 and a second seal 700. The steam panel 600 is disposed outside the steam outlet 330, thereby guiding steam evenly to the fabric through the steam panel 600. The second seal 700 is disposed between the steam panel 600 and the steam outlet 330 to prevent steam leakage.

[0091] It should be understood that the liquid water entering the steam chamber 310 from the inlet 320 needs to flow in a circuitous manner to ensure that the liquid water is fully heated and vaporized into steam within the steam chamber 310. Therefore, referring to... Figure 11As shown, in some embodiments, the steam chamber 310 includes two flow channels 311, which are arranged in a roundabout manner. The first ends of the two flow channels 311 in the extension direction converge at the water inlet 320, and the last ends of the two flow channels 311 in the extension direction are connected to the steam outlet 330.

[0092] Thus, when liquid water enters the steam chamber 310 from the inlet 320, it can enter the higher temperature part of the steam chamber 310 and be diverted to two flow channels 311. This allows the liquid water to be heated and vaporized as it flows along the extension direction of the flow channel 311, or allows the steam to be vaporized more completely and fully as it flows along the extension direction of the flow channel 311, before being ejected from multiple steam outlets 330.

[0093] Reference Figure 6 As shown, in some embodiments, the first heating element 110 further includes two third heating segments 113. The two third heating segments 113 extend along a straight line and are arranged in parallel. The third heating segments 113 are arranged in a one-to-one correspondence with the second heating segments 112 and are connected to the end of the second heating segment 112 away from the first heating segment 111.

[0094] The second heating element 210 includes a fourth heating section 211 and two fifth heating sections 212. The two fifth heating sections 212 are connected to both ends of the fourth heating section 211 and are arranged in parallel.

[0095] In other words, the first heating element 110 can be made of an electric heating tube bent into a shape similar to M, and the second heating element 210 can be made of an electric heating tube bent into a shape similar to U. In this way, the first heating element 110 and the second heating element 210 can fill the steam chamber 310, thereby uniformly heating the liquid water or air in various parts of the steam chamber 310, so that the steam production in the steam chamber 310 is more uniform.

[0096] In addition, refer to Figure 12 As shown in the illustration, this application also provides an ironing device, which includes a steam generator 10 and a device body, with the steam generator 10 connected to the device body. The structure and working principle of the steam generator 10 have been described in detail in the foregoing embodiments and will not be repeated here.

[0097] For example, the ironing equipment can be a handheld steam brush, an ironing machine, etc., but this embodiment does not limit it.

[0098] Reference Figure 12As shown, in one possible implementation, the device body includes a control component 20, a drive pump 30, and a water tank 40. The steam generator 10 includes a first heating component 100, a second heating component 200, and a housing 300. The first heating component 100, the second heating component 200, and the drive pump 30 are all electrically connected to the control component 20. The water tank 40 is used to store liquid. Both the housing 300 and the water tank 40 are connected to the drive pump 30, which drives the liquid in the water tank 40 into the housing 300.

[0099] Thus, when the ironing equipment starts working, the first heating element 110 and the second heating element 210 together heat the steam chamber 310. When the temperature of the steam chamber 310 reaches the vaporization temperature, the control component 20 controls the drive pump 30 to drive the liquid water from the water tank 40 into the steam chamber 310, thereby causing the liquid water to vaporize into steam. Throughout the entire working process, the control component 20 can control the drive pump 30 to continuously replenish water to the steam chamber 310, and both the first heating element 100 and the second heating element 200 are electrically connected to the control component 20, so that... Figure 7 The schematic equivalent circuit is connected to the ironing equipment circuit.

[0100] The control component 20 can be used to control the first heating component 100 and the second heating component 200. For example, the control component 20 can adjust the power of the first heating component 110 and the second heating component 210, or the control component 20 can adjust the power-off temperature and power-on temperature of the first temperature control 120 and the second temperature control 220.

[0101] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
