Description

Technical Field

[0001] This application relates to the field of garment care technology, and more particularly to a steam generating structure and an ironing machine. Background Technology

[0002] A steam iron is a device that uses high-temperature steam to iron clothes. Its core function is to heat water in a boiler to generate steam, which is then sprayed out through nozzles on the ironing panel to iron clothes.

[0003] In related technologies, the boiler has an internal flow channel, and the boiler has a water inlet and a steam outlet that communicate with the flow channel. Water can enter the flow channel through the water inlet, and the flow channel is heated by a heating element (such as an electric heating wire) to vaporize the water into steam, which is then ejected through the steam outlet.

[0004] However, during steam generation, scale (such as calcium carbonate, magnesium salts, etc.) tends to deposit on the flow channel at the drain point corresponding to the inlet, causing the flow channel cross-sectional area to shrink or even become completely blocked, thus affecting the steam generation efficiency. Utility Model Content

[0005] This application provides a steam generating structure and an iron to solve the problem of scale buildup at the water inlet, which affects steam generation efficiency.

[0006] Firstly, the steam generating structure provided in this application includes:

[0007] The cover has a water inlet.

[0008] A heating element is connected to a cover to form a first evaporation chamber. A water inlet is connected to the first evaporation chamber. A first steam outlet connected to the first evaporation chamber is provided on the heating element.

[0009] The diverter is installed in the first evaporation chamber and is positioned corresponding to the water inlet to divert the liquid entering from the water inlet.

[0010] A guide channel is provided inside the first evaporation chamber. The guide channel connects the upper and lower sides of the flow divider. The guide channel is configured to guide part of the steam in the first evaporation chamber to the upper side of the flow divider so that the steam can carry away the scale deposited on the upper side of the flow divider.

[0011] Thus, by installing a diverter at the inlet, the liquid entering through the inlet is diverted, allowing it to flow evenly to different locations within the first evaporation chamber, thereby improving the vaporization efficiency of the liquid in the first evaporation chamber. Furthermore, the first evaporation chamber is equipped with guide channels connecting the upper and lower sides of the diverter to guide the steam generated on the lower side of the diverter to the upper side. This steam flushes the high-concentration scale and liquid mixture collected on the upper side of the diverter into the first evaporation chamber, preventing scale buildup on the upper side of the diverter and potential blockage of the inlet.

[0012] In one possible implementation, the steam generating structure provided in this application further includes a base plate, a heating element and a cover are arranged in sequence, the base plate and the heating element form a second evaporation chamber, and a first steam outlet connects the first evaporation chamber and the second evaporation chamber;

[0013] A second steam outlet, which communicates with the second evaporation chamber, is provided on the bottom plate.

[0014] In this way, the liquid enters the first evaporation chamber through the inlet and gradually transforms into steam. The steam and residual liquid (i.e., the liquid that did not transform into steam in the first evaporation chamber) enter the second evaporation chamber through the first steam outlet, where secondary vaporization occurs. This improves the conversion rate and vaporization efficiency of the liquid to steam and avoids heat waste on the side of the heating element away from the first evaporation chamber, thus improving heat utilization. Subsequently, the steam in the second evaporation chamber can be ejected through the second steam outlet.

[0015] In one possible implementation, the steam generating structure provided in this application further includes a second baffle, which is disposed in the second evaporation chamber and divides the second evaporation chamber into a liquid inlet channel, a steam channel and at least two branch channels.

[0016] Each branch channel is connected to the liquid inlet channel and the steam channel respectively. The first steam outlet is connected to the liquid inlet channel, and the second steam outlet is connected to the steam channel.

[0017] In this way, the mixture of steam and residual liquid enters the liquid inlet channel through the first steam outlet, and is then divided into multiple branches. Each branch enters its respective branch channel, thus dispersing the residual liquid circumferentially within the second evaporation chamber. This increases the liquid's coverage area and uniformity within the second evaporation chamber, improves vaporization efficiency, and prevents liquid from accumulating at the bottom of the second evaporation chamber due to the iron's operating angle. Afterward, the liquid in each branch channel enters the steam channel.

[0018] In one possible implementation, the steam generating structure provided in this application has two second notches on the second baffle. The sidewall of the second notch, part of the heating element and part of the bottom plate form a second confluence area. One end of each branch flow channel is connected to the liquid inlet flow channel through a second confluence area, and the other end of each branch flow channel is connected to the steam flow channel through another second confluence area.

[0019] Thus, by setting up a second confluence zone, the liquids in each branch channel are fully mixed in the second confluence zone, so as to balance the heat difference of the liquids in each branch channel, improve the temperature uniformity of the liquid, and thus improve the vaporization effect.

[0020] In one possible implementation, the steam generating structure provided in this application further includes a third baffle, which is disposed in the liquid inlet channel to divide the liquid inlet channel into at least two liquid inlet branch channels.

[0021] The number of first steam outlets is at least two, and the first steam outlets are connected to the corresponding liquid inlet branch channels. The end of the liquid inlet branch channel away from the first steam outlet is connected to the second confluence area.

[0022] In this way, the liquid in the first evaporation chamber is divided into two branches through at least two first steam outlets and enters each liquid inlet branch channel of the second evaporation chamber in sequence. This increases the liquid spreading area and uniformity in the liquid inlet channel and avoids the liquid accumulating at the bottom of the liquid inlet channel due to the angle of use of the iron.

[0023] In one possible implementation, the steam generating structure provided in this application further includes a first baffle, which is disposed in the first evaporation chamber to divide the first evaporation chamber into a first flow channel and a second flow channel. A flow divider is disposed in the first flow channel, and the second flow channel is connected to the first steam outlet.

[0024] The gaps between part of the first baffle, the side wall of the diversion component, part of the heating element, and part of the cover form a guide channel.

[0025] In this way, the liquid at the inlet can be diverted and diffused to the surrounding area of ​​the first flow channel through the diverter, so as to increase the liquid coverage and uniformity in the first flow channel, and then the liquid flows to the first steam outlet through the second flow channel.

[0026] In one possible implementation, the steam generating structure provided in this application has a first flow channel surrounding the outside of a second flow channel, and a flow divider separates the first flow channel into two first branch channels, which are respectively connected to the second flow channel.

[0027] Thus, this flow channel design within the first evaporation chamber allows the liquid to be evenly dispersed within the chamber and distributed to different locations to fully absorb heat. Furthermore, by using a diverter to distribute the liquid from the inlet to each of the first branch channels, liquid accumulation at the bottom of the first evaporation chamber due to the iron's angle of use can be avoided.

[0028] In one possible implementation, the steam generating structure provided in this application has a first notch on the first baffle, and the sidewall of the first notch, part of the heating element and part of the cover together form a first confluence area, and the two first branch channels are connected to the second channel through the first confluence area.

[0029] In this way, the liquids in the two first branch channels converge and mix in the first confluence zone before entering the second channel. By setting up the first confluence zone, the liquids in the two first branch channels are fully mixed within the first confluence zone, thereby balancing the heat difference between the liquids in the two first branch channels, improving the temperature uniformity of the liquids, and thus improving the vaporization effect.

[0030] In one possible implementation, the steam generating structure provided in this application includes a first flow channel comprising a first flow channel section and a second flow channel section, with the inlet, the first flow channel section, the second flow channel section, and the second flow channel sequentially connected.

[0031] The cross-sectional area of ​​the first flow channel is larger than that of the second flow channel.

[0032] Thus, the liquid at the inlet first enters the first flow channel section, and then flows sequentially to the second flow channel section, the second flow channel, and the first steam outlet. The cross-sectional area of ​​the first flow channel section is larger than that of the second flow channel section. The larger cross-sectional area of ​​the first flow channel section promotes the diffusion of the liquid at the inlet, reducing the probability of scale buildup and blockage.

[0033] Secondly, the ironing machine provided in this application includes an ironing machine body and any of the above-mentioned steam generating structures disposed on the ironing machine body.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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, for example, in orders other than those illustrated or described herein.

[0055] 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.

[0056] In related technologies, during the steam generation process, scale (such as calcium carbonate, magnesium salts, etc.) is easily deposited on the flow channel at the water outlet corresponding to the inlet, which leads to a reduction in the cross-sectional area of ​​the flow channel or even complete blockage, affecting the steam generation efficiency.

[0057] Specifically, a diverter is installed at the drain point to distribute the liquid in all directions, allowing it to flow evenly to different locations and thus improving the vaporization efficiency of the liquid into steam. However, some liquid will collect above the diverter. When heated, the soluble minerals in this liquid (mainly calcium and magnesium ions) will transform into insoluble precipitates (i.e., scale) and adhere to the top of the diverter, causing blockage of the drain point.

[0058] In view of the above problems, this application provides a steam generating structure and an ironing machine. The steam generating structure includes a cover, a heating element, and a diverter. The cover has a water inlet, and the heating element is connected to the cover to form a first evaporation chamber. The water inlet communicates with the first evaporation chamber, and the heating element has a first steam outlet communicating with the first evaporation chamber. The diverter is disposed within the first evaporation chamber, corresponding to the water inlet, to divert liquid entering through the water inlet. A guide channel is provided within the first evaporation chamber, connecting the upper and lower sides of the diverter. The guide channel is configured to guide a portion of the steam in the first evaporation chamber towards the upper side of the diverter, so that the steam carries away the scale deposited on the upper side of the diverter. By correspondingly distributing the diverter at the water inlet, the diverter diverts the liquid entering through the water inlet, allowing the liquid to flow evenly to different positions within the first evaporation chamber, thereby improving the vaporization efficiency of the liquid in the first evaporation chamber into steam. Furthermore, the first evaporation chamber is provided with guide channels connecting the upper and lower sides of the flow divider to guide the steam generated on the lower side of the flow divider to the upper side of the flow divider. The steam is used to flush the high concentration of scale and liquid mixture collected on the upper side of the flow divider into the first evaporation chamber, so as to avoid scale deposition on the upper side of the flow divider, which would cause blockage of the water inlet.

[0059] To facilitate understanding, the application scenarios of the embodiments of this application will be described first.

[0060] The ironing machine provided in this application embodiment can be applied to clothing manufacturing, storage, sales, or laundry shops. The clothing to be ironed by the ironing machine should be interpreted broadly, including but not limited to clothes, trousers, and other items for wearing, as well as fabrics such as curtains, sheets, and duvet covers. This application embodiment does not specifically limit this, and will be collectively referred to as "clothing" below, without further specific examples.

[0061] The following describes in detail, with reference to the accompanying drawings, the specific implementation of the steam generating structure and ironing machine provided in the embodiments of this application.

[0062] Reference Figures 2 to 7 As shown, the steam generating structure 10 provided in this embodiment includes a cover 100, a heating element 200, and a flow divider 300.

[0063] A water inlet 110 is provided on the cover 100. The heating element 200 is connected to the cover 100 to form a first evaporation chamber 210. The water inlet 110 communicates with the first evaporation chamber 210. A first steam outlet 202 communicating with the first evaporation chamber 210 is provided on the heating element 200. A diverter 300 is provided in the first evaporation chamber 210. The diverter 300 is correspondingly provided with the water inlet 110 to divert the liquid entering through the water inlet 110.

[0064] The first evaporation chamber 210 is provided with a guide channel 201, which connects the upper and lower sides of the diverter 300. The guide channel 201 is configured to guide part of the steam in the first evaporation chamber 210 to the upper side of the diverter 300 so that the steam can carry away the scale deposited on the upper side of the diverter 300.

[0065] It is understood that the steam generating structure 10 provided in this application embodiment can be used in an ironing machine. The water inlet 110 on the cover 100 can be connected to the water pump in the ironing machine so that the liquid in the water tank of the ironing machine can be pumped into the water inlet 110. Then, the liquid in the first evaporation chamber 210 is heated by the heating element 200 so that the liquid vaporizes to generate high-temperature steam. The high-temperature steam can be sprayed onto the clothes through the first steam outlet 202. By penetrating the fabric with high-temperature steam, the fiber structure is softened, making stubborn wrinkles easier to smooth out and improving ironing efficiency.

[0066] Among them, reference Figures 2 to 4 As shown, a diverter 300 is provided in the first evaporation chamber 210. The diverter 300 is correspondingly provided with the inlet 110. The liquid at the inlet 110 can be diverted to the surrounding area of ​​the first evaporation chamber 210 through the diverter 300, so as to increase the spreading area and uniformity of the liquid in the first evaporation chamber 210, thereby improving the heat utilization rate in the first evaporation chamber 210, improving the vaporization efficiency of the liquid and the conversion rate of the liquid to steam.

[0067] For example, the diversion component 300 can be a diversion baffle, a diversion protrusion, a diversion partition, or other structures, as long as it can divert the liquid at the inlet 110 to the surrounding areas, and there are no restrictions here.

[0068] Furthermore, refer to Figures 2 to 4 As shown, a guide channel 201 is provided inside the first evaporation chamber 210. The guide channel 201 can guide the steam generated on the lower side of the distributor 300 to the upper side of the distributor 300. The steam is used to flush the high-concentration scale and liquid mixture collected on the upper side of the distributor 300 into the first evaporation chamber 210, so as to prevent scale from depositing on the upper side of the distributor 300 and causing blockage of the inlet 110. The high-concentration scale and liquid mixture can flow from the upper side of the distributor 300 to the bottom of the first evaporation chamber 210 through the guide channel 201.

[0069] In summary, in this embodiment, by providing a diverter 300 at the inlet 110, the diverter 300 diverts the liquid entering through the inlet 110, allowing the liquid to flow evenly to different positions in the first evaporation chamber 210, thereby improving the vaporization efficiency of the liquid in the first evaporation chamber 210 into steam. Furthermore, the first evaporation chamber 210 is provided with guide channels 201 connecting the upper and lower sides of the diverter 300, guiding the steam generated on the lower side of the diverter 300 to the upper side. The steam then flushes the high-concentration scale and liquid mixture collected on the upper side of the diverter 300 into the first evaporation chamber 210, preventing scale buildup on the upper side of the diverter 300 and potential blockage of the inlet 110.

[0070] Reference Figure 2 , Figure 6 and Figure 7 As shown, in some embodiments, the steam generating structure 10 provided in this application further includes a base plate 400, the base plate 400, the heating element 200 and the cover 100 are arranged in sequence, the base plate 400 and the heating element 200 form a second evaporation chamber 220, the first steam outlet 202 connects the first evaporation chamber 210 and the second evaporation chamber 220, and the base plate 400 is provided with a second steam outlet that communicates with the second evaporation chamber 220.

[0071] It is understood that the first evaporation chamber 210 and the second evaporation chamber 220 are respectively located on opposite sides of the heating element 200. The heat generated by the heating element 200 towards the cover 100 enters the first evaporation chamber 210, and the heat generated by the heating element 200 towards the bottom plate 400 enters the second evaporation chamber 220.

[0072] In this way, the liquid enters the first evaporation chamber 210 through the inlet 110, where it is gradually converted into steam. The steam and residual liquid (i.e., the liquid that was not converted into steam in the first evaporation chamber 210) enter the second evaporation chamber 220 through the first steam outlet 202, where secondary vaporization occurs. This improves the conversion rate and vaporization efficiency of the liquid to steam and avoids heat waste on the side of the heating element 200 away from the first evaporation chamber 210, thus improving heat utilization. Subsequently, the steam in the second evaporation chamber 220 can be ejected through the second steam outlet.

[0073] The soleplate 400 forms the ironing panel of the ironing machine, providing a flat support surface for the garments so that they can be evenly heated and shaped by steam. The soleplate 400 can be made of a high-temperature resistant, scratch-resistant material, such as a ceramic coating, stainless steel, or Teflon. The smooth surface of the soleplate 400 reduces friction and prevents snagging or damage to the garments.

[0074] Reference Figure 6 and Figure 7 As shown, area 'a' corresponds to the location of the second steam outlet on the base plate 400. There can be multiple second steam outlets to ensure that steam is evenly distributed onto the clothing.

[0075] Reference Figure 2 As shown, in one embodiment, the heating element 200 includes a heat-conducting housing portion 203 and a heating portion 204, with the heat-conducting housing portion 203 surrounding the outer periphery of the heating portion 204. The base plate 400 and the cover 100 are respectively connected to the heat-conducting housing portion 203. The heating portion 204 can generate heat by being energized, and the heat generated by the heating portion 204 can be transferred through the heat-conducting housing portion 203 to the first evaporation chamber 210 and the second evaporation chamber 220.

[0076] For example, the heating element 204 includes, but is not limited to, an electric heating tube, wherein the electric heating tube may be located in the heat-conducting housing 203 in an S-shaped, U-shaped, or spiral shape to increase the laying area of ​​the electric heating tube. The heat-conducting housing 203 may be formed of a heat-conducting material, for example, the heat-conducting housing 203 includes, but is not limited to, a heat-conducting material such as aluminum.

[0077] Reference Figure 2 , Figure 6 and Figure 7 As shown, in some embodiments, the steam generating structure 10 provided in this application further includes a second baffle 520, which is disposed in the second evaporation chamber 220 and divides the second evaporation chamber 220 into a liquid inlet channel 221, a steam channel 222 and at least two branch channels 223.

[0078] Each branch flow channel 223 respectively communicates the liquid inlet flow channel 221 and the steam flow channel 222, the first steam outlet 202 communicates with the liquid inlet flow channel 221, and the second steam outlet communicates with the steam flow channel 222.

[0079] With reference to Figure 7 , the solid arrows in the figure are schematic diagrams of the flow direction of the fluid in the second evaporation chamber 220. In this way, the mixture of steam and residual liquid enters the liquid inlet flow channel 221 through the first steam outlet 202, then is divided into a plurality of branch flows, and each branch flow respectively enters each branch flow channel 223, so that the residual liquid can be circumferentially dispersed in the second evaporation chamber 220, which increases the laying area and uniformity of the liquid in the second evaporation chamber 220, improves the vaporization efficiency, and avoids the liquid from accumulating at the bottom of the second evaporation chamber 220 due to the use angle of the ironing machine. Thereafter, the liquid in each branch flow channel 223 respectively enters the steam flow channel 222.

[0080] With reference to Figure 2 , Figure 6 and Figure 7 , in some embodiments, two second notches are provided on the second rib 520, the side wall of the second notch, a part of the heating element 200 and a part of the bottom plate 400 form a second confluence area 521, one end of each branch flow channel 223 communicates with the liquid inlet flow channel 221 through one second confluence area 521, and the other end of each branch flow channel 223 communicates with the steam flow channel 222 through another second confluence area 521.

[0081] In this way, the dispersed liquid in the liquid inlet flow channel 221 is mixed in the second confluence area 521, and dispersed from the second confluence area 521 to the plurality of branch flow channels 223, and the liquid in each branch flow channel 223 is converged and mixed in another second confluence area 521, and then enters the steam flow channel 222. By providing the second confluence area 521, the liquid in each branch flow channel 223 can be sufficiently mixed in the second confluence area 521, so as to balance the heat difference of the liquid in each branch flow channel 223 and improve the uniformity of the liquid temperature, thereby improving the vaporization effect.

[0082] With reference to Figure 6 and Figure 7 , in a specific embodiment, the second rib 520 is in a "Japanese-shaped" structure, the two chambers of the "Japanese-shaped" structure respectively form the liquid inlet flow channel 221 and the steam flow channel 222, and the two second notches are respectively provided at opposite ends of the second rib 520. Wherein, the number of the branch flow channels 223 is two, and the two branch flow channels 223 are wound around the peripheral sides of the liquid inlet flow channel 221 and the steam flow channel 222.

[0083] In this way, the layout design of each flow channel in the second evaporation chamber 220 can increase the spreading area and uniformity of the liquid in the second evaporation chamber 220, and avoid the liquid from accumulating at the bottom of the second evaporation chamber 220 due to the angle of use of the iron.

[0084] Reference Figure 4 , Figure 6 and Figure 7 As shown, in some embodiments, the steam generating structure 10 provided in this application further includes a third baffle 530, which is disposed in the liquid inlet channel 221 to divide the liquid inlet channel 221 into at least two liquid inlet branch channels 2211.

[0085] The number of first steam outlets 202 is at least two. The first steam outlets 202 are connected to the corresponding liquid inlet branch channel 2211. The end of the liquid inlet branch channel 2211 away from the first steam outlets 202 is connected to the second confluence area 521.

[0086] In this way, the liquid in the first evaporation chamber 210 is divided into two branches through at least two first steam outlets 202 and enters each liquid inlet branch channel 2211 of the second evaporation chamber 220 in sequence. This increases the liquid spreading area and uniformity in the liquid inlet channel 221 and avoids the liquid accumulating at the bottom of the liquid inlet channel 221 due to the angle of use of the iron.

[0087] Furthermore, the liquids in each inlet branch channel 2211 are collected and mixed in the second confluence zone 521, and then the liquids in the second confluence zone 521 are distributed to each branch channel 223. In this way, the liquids in each inlet branch channel 2211 are fully mixed in the second confluence zone 521, balancing the heat differences of the liquids in each inlet branch channel 2211, improving the temperature uniformity of the liquids, and thus improving the vaporization effect.

[0088] Specifically, refer to Figure 6 As shown, there are two first steam outlets 202 and two liquid inlet branch channels 2211. The two first steam outlets 202 are symmetrically arranged with respect to the third baffle 530, and the two liquid inlet branch channels 2211 are symmetrically arranged with respect to the third baffle 530.

[0089] Reference Figure 6 and Figure 7 As shown, in one embodiment, a fourth baffle 540 is provided in the steam flow channel 222, which divides the steam flow channel 222 into at least two steam branch channels 2221. One end of each steam branch channel 2221 is connected to a second confluence area 521 away from the liquid inlet channel 221, and the other end of each steam branch channel 2221 is connected to and corresponding to a second steam outlet on the bottom plate 400.

[0090] In this way, after the liquid in each branch channel 223 enters the steam channel 222 from the second confluence area 521, it is again diverted to each steam branch channel 2221 by the fourth baffle 540, thereby increasing the coverage area and uniformity of the liquid in the steam channel 222 and avoiding the accumulation of liquid at the bottom of the steam channel 222 due to the angle of use of the ironing machine.

[0091] Specifically, refer to Figure 6 As shown, there are two steam branch channels 2221, and the two steam branch channels 2221 are symmetrically arranged relative to the fourth baffle 540.

[0092] Reference Figure 3 , Figure 4 and Figure 5 As shown, in one embodiment, the steam generating structure 10 provided in this application further includes a first baffle 510, which is disposed in the first evaporation chamber 210 to divide the first evaporation chamber 210 into a first flow channel 211 and a second flow channel 212. A flow divider 300 is disposed in the first flow channel 211, and the second flow channel 212 is connected to the first steam outlet 202.

[0093] In this way, the liquid in the inlet 110 can be diverted and diffused to the periphery of the first flow channel 211 through the diverter 300, so as to increase the spreading area and uniformity of the liquid in the first flow channel 211, and then the liquid flows to the first steam outlet 202 through the second flow channel 212.

[0094] Reference Figure 3 As shown, the gap between part of the first baffle 510, the side wall of the diversion component 300, part of the heating element 200 and part of the cover 100 forms a guide channel 201, so that no additional pipe structure is required and the overall structure is simple and compact.

[0095] Reference Figure 4 As shown, the upper side of the diverter 300 is the location indicated by the +X direction in the figure, and the lower side of the diverter 300 is the location indicated by the -X direction in the figure. When using the iron, some of the steam in the first evaporation chamber 210 can flow from the lower side to the upper side of the diverter 300 through the guide channel 201, thereby flushing the high-concentration scale and liquid mixture collected on the upper side of the diverter 300 into the first evaporation chamber 210 along the guide channel 201, so as to avoid scale deposition on the upper side of the diverter 300, which would block the water inlet 110. The X direction (from +X to -X) is the vertical direction.

[0096] Reference Figure 3 , Figure 4 and Figure 5As shown, in some embodiments, the first flow channel 211 is disposed around the outside of the second flow channel 212, and the flow divider 300 divides the first flow channel 211 into two first branch flow channels 2111, which are respectively connected to the second flow channel 212.

[0097] Reference Figure 5 As shown in the figure, the solid arrows indicate the flow direction of the fluid in the first evaporation chamber 210. The liquid at the inlet 110 is divided into two branches by the diverter 300. Each branch enters the first branch channel 2111 sequentially. The first branch channel 2111 causes the branches to flow around the outer periphery of the second channel 212, finally converging in the second channel 212. This channel design within the first evaporation chamber 210 allows the liquid to be evenly dispersed within the chamber and diverted to different locations within it. This ensures sufficient heat absorption within the first evaporation chamber 210 before the liquid flows sequentially through the second channel 212 and the first steam outlet 202 to the second evaporation chamber 220, improving heat utilization efficiency and enhancing water vaporization efficiency and conversion rate.

[0098] Furthermore, by diverting the liquid at the inlet 110 to each of the first branch channels 2111 through the diverter 300, it is possible to avoid the liquid accumulating at the bottom of the first evaporation chamber 210 due to the angle of use of the iron.

[0099] Reference Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, a first notch is provided on the first baffle 510, and the sidewall of the first notch, part of the heating element 200 and part of the cover 100 together form a first confluence area 511, and the two first branch channels 2111 are connected to the second channel 212 through the first confluence area 511.

[0100] In this way, the liquids in the two first branch channels 2111 are converged and mixed in the first confluence zone 511 before entering the second channel 212. By setting up the first confluence zone 511, the liquids in the two first branch channels 2111 are fully mixed in the first confluence zone 511 to balance the heat difference between the liquids in the two first branch channels 2111, improve the temperature uniformity of the liquid, and thus improve the vaporization effect.

[0101] Among them, reference Figure 4 As shown, the diverter 300 and the first confluence area 511 are respectively disposed on opposite sides of the first baffle 510, so as to extend the path of the first branch channel 2111 and ensure that the liquid in the first branch channel 2111 fully absorbs heat.

[0102] Reference Figure 4As shown, a fifth baffle 550 is provided in the second flow channel 212, which divides the second flow channel 212 into at least two second branch channels 2121. A third confluence area 551 is formed between the fifth baffle 550 and the first baffle 510. One end of each second branch channel 2121 is connected to the first confluence area 511, and the other end of each second branch channel 2121 is connected to the third confluence area 551. The third confluence area 551 is connected to the first steam outlet 202.

[0103] In this way, after the liquid in each first branch channel 2111 enters the second channel 212 from the first confluence area 511, it is again diverted to each second branch channel 2121 by the fifth baffle 550, thereby increasing the coverage area and uniformity of the liquid in the second branch channel 2121 and avoiding the accumulation of liquid at the bottom of the second channel 212 due to the angle of use of the ironing machine.

[0104] Furthermore, the liquids in each of the second branch channels 2121 are fully mixed in the third confluence zone 551 to balance the heat difference of the liquids in each of the second branch channels 2121, improve the uniformity of the liquid temperature, and thus improve the vaporization effect.

[0105] Specifically, refer to Figure 4 As shown, there are two second branch channels 2121, and the two second branch channels 2121 are symmetrically arranged relative to the fifth baffle 550.

[0106] Reference Figure 4 and Figure 5 As shown, in some embodiments, the first branch channel 2111 includes a first channel section 2112 and a second channel section 2113, and the inlet 110, the first channel section 2112, the second channel section 2113, and the second channel 212 are connected in sequence. The cross-sectional area of ​​the first channel section 2112 is larger than the cross-sectional area of ​​the second channel section 2113.

[0107] In this way, the liquid at the inlet 110 first enters the first flow channel section 2112, and then flows sequentially to the second flow channel section 2113, the second flow channel 212, and the first steam outlet 202. The cross-sectional area of ​​the first flow channel section 2112 is larger than that of the second flow channel section 2113. The larger cross-sectional area of ​​the first flow channel section 2112 promotes the diffusion of the liquid at the inlet 110, reducing the probability of scale buildup and blockage.

[0108] Reference Figure 1 As shown, the ironing machine provided in this application includes an ironing machine body 20 and a steam generating structure 10, as described above, disposed on the ironing machine body 20.

[0109] Since the ironing machine adopts the steam generating structure 10 in the above embodiment, it also has the advantages and benefits brought by the steam generating structure 10, which will not be elaborated further here.
