[0033] The principles and features of the present application are described below in conjunction with the accompanying drawings, in which the examples are presented only to explain the present application and are not intended to limit the scope of the present application.

[0034] In-depth research into the ironing process reveals that it generally consists of four parts: localized shaping ironing, localized steam ironing, large-area ironing, and final ironing of remaining details. Based on this understanding, the steam requirements differ at each stage. In the first step, localized shaping ironing, the steam demand is relatively low, and dry ironing without steam is also possible. The second step, localized steam ironing, requires a smaller steam area, necessitating steam output in specific locations to improve steam utilization. The third step, large-area ironing, requires a large area of ​​regular steam to enhance ironing efficiency. Finally, the final step, ironing of remaining details, requires a small amount of high-temperature steam to achieve detailed shaping. Existing garment steamers cannot adequately meet the needs of practical applications, resulting in low energy utilization and low ironing efficiency.

[0035] like Figures 1 to 13 As shown, an embodiment of the present invention provides a heating assembly 100, including a heater 1 and a regulating valve 2.

[0036] like Figures 1-10 As shown, the heater 1 is provided with a first steam chamber 11 and a second steam chamber 12, which are connected in parallel. The heating assembly 100 can be used in a steam-spraying device, such as an ironing head, and the first steam chamber 11 can be connected to a first steam nozzle 31 on the ironing head, and the second steam chamber 12 can be connected to a second steam nozzle 32 on the ironing head, so that the steam delivered through the first steam chamber 14 is ejected from the first steam nozzle 31, and the steam delivered through the second steam chamber 15 is ejected from the second steam nozzle 32.

[0037] like Figures 6 to 13 As shown, the regulating valve 2 is provided with a connecting channel 21, a steam inlet 22, and a steam outlet 23. The inlet side of the connecting channel 21 is configured to communicate with the steam inlet 22, and the outlet side of the connecting channel 21 is configured to communicate with the steam outlet 23, so that the steam inlet 22 and the steam outlet 23 are connected through the connecting channel 21 to form a steam channel 20. Steam enters the steam channel 20 from the steam inlet 22 and flows out of the regulating valve 2 via the steam outlet 23. The regulating valve 2 can control the steam outlet 23 to be connected to the first steam chamber 11, or to be connected to the second steam chamber 12, or to be connected to both the first steam chamber 11 and the second steam chamber 12 simultaneously, so that the steam channel 20 is connected to at least one of the first steam chamber 11 and the second steam chamber 12, allowing the heating assembly 100 to have different operating modes.

[0038] The heating assembly 100 of this application embodiment, by providing two parallel steam chambers—a first steam chamber 11 and a second steam chamber 12—within the heater 1, and controlling the regulating valve 2 to connect the steam channel 20 to at least one of the two steam chambers, can achieve multiple operating modes for the heating assembly 100. Specifically, operating the regulating valve 2 connects the steam channel 20 to the first steam chamber 11, allowing steam to exit from the first steam nozzle 31; or, operating the regulating valve 2 connects the steam channel 20 to the second steam chamber 12, allowing steam to exit from the second steam nozzle 32; or, operating the regulating valve 2 connects the steam channel 20 to both the first steam chamber 11 and the second steam chamber 12 simultaneously, allowing steam to exit from both the first steam nozzle 31 and the second steam nozzle 32 simultaneously (the steam flow direction is as follows). Figure 1 (As shown by the middle arrow). The ironing area can be adjusted by emitting steam from different steam nozzles.

[0039] The heating component 100 in this embodiment achieves a matching design between the functional design of the heating component 100 and actual needs, effectively improving energy utilization and the ironing efficiency of the whole machine with the heating component 100 installed.

[0040] It should be understood that the heater 1 is not limited to having two steam chambers connected in parallel: a first steam chamber 11 and a second steam chamber 12. It may also have three or more steam chambers connected in parallel, and correspondingly, the three or more steam chambers connected in parallel may be connected to different steam nozzles.

[0041] In some exemplary embodiments, such as Figure 1 As shown, a first steam channel is provided in the first steam chamber 11, and a second steam channel is provided in the second steam chamber 12. The first and second steam channels can be configured with flow paths of different lengths. For example, the first steam channel has a longer flow path, and the second steam channel has a shorter flow path than the first steam channel. This allows steam to flow only a shorter path in the second steam channel before being ejected from the second steam nozzle 32 and onto the surface of the clothing, resulting in a high steam velocity in this mode. Conversely, steam needs to flow a longer path in the first steam channel before being ejected from the first steam nozzle 31, resulting in a lower steam velocity in this mode (assuming that the number and area of ​​the first and second steam nozzles 31 and 32 are equal, and ignoring the influence of steam nozzles and other factors on the steam velocity).

[0042] It should be understood that the lengths of the flow paths of the first steam channel and the second steam channel can also be set to be equal.

[0043] In some exemplary embodiments, such as Figures 1-4As shown, the heater 1 is configured to also include a third steam chamber 13. The third steam chamber 13 is configured to be connected to the steam inlet 22 of the regulating valve 2, so that the third steam chamber 13 and the steam channel 20 are connected. Steam can flow into the steam channel 20 of the regulating valve 2 through the steam inlet 22 via the third steam chamber 13, and then flow out through the steam outlet 23 to enter the first steam chamber 11 or the second steam chamber 12, or the first steam chamber 11 and the second steam chamber 12, and then be ejected from the steam nozzle (the first steam nozzle 31 or the second steam nozzle 32, or the first steam nozzle 31 and the second steam nozzle 32) to achieve different steam ironing functions.

[0044] In some exemplary embodiments, such as Figures 1-2 As shown, heater 1 is configured to include a first part 18, a second part 14, and a third part 15, which are stacked sequentially. For example, the first part 18 can be located above the second part 14, and the third part 15 can be located below the second part 14. The first part 18 and the second part 14 cooperate to form a third steam chamber 13, and the second part 14 and the third part 15 cooperate to form a fourth steam chamber 19. The fourth steam chamber 19 is provided with a partition 16, which can divide the fourth steam chamber 19 to form a first steam chamber 11 and a second steam chamber 12. Figure 3 and Figure 4 As shown, the separator 16 can be configured to include two cylindrical structures or plate-like structures.

[0045] The heater 1, comprising a first part 18, a second part 14, and a third part 15, forms a stacked sandwich structure. The second part 14 is located in the middle of the heater 1, and the third steam chamber 13 is disposed on one side of the second part 14. The first steam chamber 11 and the second steam chamber 12 are disposed side by side on the other side of the second part 14. Steam can pass through the third steam chamber 13 on one side and enter the first steam chamber 11 and / or the second steam chamber 12 on the other side via the steam passage 20 of the regulating valve 1.

[0046] In some exemplary embodiments, such as Figure 3 and Figure 4 As shown, the heater 1 is further configured to include a heating element 17, which is located within the third steam chamber 13 and can be mounted on the second part 14. This allows the heating element 17 to directly heat the steam flowing through the third steam chamber 13 and transfer the heat to the first steam chamber 11 and the second steam chamber 12 via the second part 14, thereby heating the steam flowing through the first steam chamber 11 and the second steam chamber 12. In this way, the steam is reheated as it flows through the first steam chamber 11 and the second steam chamber 12, increasing the temperature of the steam ejected from the first steam nozzle 31 and the second steam nozzle 32, thus improving the ironing effect.

[0047] It should be understood that the heating element 17 can heat any one or more of the first steam chamber 11, the second steam chamber 12, and the third steam chamber, that is, the heating element 17 can heat part or all of the steam chambers.

[0048] In some exemplary embodiments, such as Figure 1 , Figures 3-4 As shown, the second part 14 has a mounting hole 141 through which the regulating valve 2 can pass, so that a part of the regulating valve 2 extends into the third steam chamber 13, and the other part is located between the second part 14 and the third part 15. The inlet side (i.e., steam inlet 22) of the steam passage 20 can be set on the part of the regulating valve 2 that extends into the third steam chamber 13 (i.e., set on the part of the regulating valve 2 that communicates with the third steam chamber 13), and the outlet side (i.e., steam outlet 23) of the steam passage 20 is set on the part of the regulating valve 2 located between the second part 14 and the third part 15, so that the outlet side of the steam passage 20 can communicate with the first steam chamber 11 and / or the second steam chamber 12, so that the steam from the third steam chamber 13 enters the steam passage 20 from the steam inlet 22, and the steam flowing out of the steam outlet 23 enters the first steam chamber 11 and / or the second steam chamber 12.

[0049] In some exemplary embodiments, such as Figure 1 As shown, the first part 18 has an inlet 181, through which steam can enter the heating assembly 100 and be reheated within the heating assembly 100; or, water can enter the heating assembly 100 through the inlet 181 of the first part 18 and be heated into steam within the heating assembly 100.

[0050] In some exemplary embodiments, such as Figure 3 and Figure 4 As shown, the heating element 17 can be configured to include a heating tube, which can be in the form of an open annular shape (such as a U-shape). Both ends of the opening of the heating tube are provided with terminals 171 for electrical connection, allowing connection to a power source. The two terminals 171 of the heating tube can be located on the first side of the heating assembly 100. Figure 4 The regulating valve 2 is located on the outside of the heating tube and on the second side of the heating assembly 100 (upper side). Figure 4 (the lower side of the heating assembly 100), wherein the first and second sides of the heating assembly 100 are opposite each other.

[0051] The regulating valve 2 is located on the outside of the heating tube to reduce the transfer of heat generated by the heating tube to the regulating valve 2 and prevent the regulating valve 2 from overheating. In addition, the regulating valve 2 is located on the side opposite to the two terminals 171 of the heating tube, so that the regulating valve 2 is away from the two terminals 171 of the heating tube and does not affect the wiring.

[0052] In some exemplary embodiments, such as Figures 1-2 , Figures 6 to 13 As shown, the regulating valve 2 is configured to include a valve body 24 and a valve core 25. The valve body 24 is fixedly disposed, and the valve core 25 is fitted inside the valve body 24 and can move relative to the valve body 24. For example, the valve core 25 can rotate inside the valve body 24 or slide along the axis to realize that the valve core 25 is movably installed inside the valve body 24.

[0053] The connecting channel 21, steam inlet 22, and steam outlet 23 that form the steam channel 20 are all located on the valve core 25.

[0054] The valve body 24 is provided with a first connecting hole 241 and a second connecting hole 242. The first connecting hole 241 is configured to communicate with the first steam chamber 11, and the second connecting hole 242 is configured to communicate with the second steam chamber 12.

[0055] It should be understood that when the valve core 24 moves, the steam outlet 23 is configured to be connected to the first connecting hole 241, or to the second connecting hole 242, or to both connecting holes (the first connecting hole 241 and the second connecting hole 242).

[0056] In some exemplary embodiments, such as Figures 7 to 10 As shown, the valve core 25 can rotate within the valve body 24. The first connecting hole 241 and the second connecting hole 242 are located at the same height of the valve body 24 and are spaced 180 degrees apart. It should be understood that the interval between the first connecting hole 241 and the second connecting hole 242 can also be set to any other angle value.

[0057] A steam outlet 23, disposed on the valve core 25, is arranged circumferentially along the valve core 25 and is positioned at the same height as the first connecting hole 241 and the second connecting hole 242. The steam outlet 23 is arranged circumferentially along the valve core 25, for example, in a circumferential arc shape, and is positioned to extend within a 270-degree range (or other angular range), such that when the valve core 25 rotates to the first position, as... Figure 10 As shown, the steam outlet 23 can be connected only to the first connecting hole 241, thereby achieving connection with the first steam passage 11; when the valve core 25 rotates to the second position, as... Figure 8 and Figure 9 As shown, the steam outlet 23 can be connected only to the second connecting hole 242, thereby achieving connection with the second steam passage 12; when the valve core 25 rotates to the third position, as... Figure 6 and Figure 7 As shown, the steam outlet 23 can be connected to the first connecting hole 241 and the second connecting hole 242 at the same time, thereby achieving simultaneous connection with the first steam channel 11 and the second steam channel 12.

[0058] It should be understood that the steam outlet 23 can also be configured to extend in a non-270-degree circumferential direction, so that steam can flow out from the steam outlet 23 and enter the first steam chamber 11 and the second steam chamber 12 respectively.

[0059] In some exemplary embodiments, the valve body 24 is configured to be integrally formed with one of the second portion 14 and the third portion 15 of the heater 1. For example... Figure 1 and Figure 2 As shown, the valve body 24 and the third part 15 of the heater 1 are integrally formed, which can effectively simplify the design structure, reduce the number of parts, and simplify the assembly process.

[0060] In this embodiment of the heating assembly 100, when steam flows out through the first steam chamber 11, because the first steam chamber 11 has a relatively long flow path, the steam can be sufficiently heated after flowing out of the third steam chamber 13, resulting in high-temperature steam. Since the steam is ejected through the first steam nozzle 31, and not all of the nozzles (only some), the steam has a high ejection velocity. This operating mode can be called the high-temperature, high-steam-flow-rate mode (the operating state of the regulating valve 2 is as follows). Figure 10 (As shown).

[0061] When steam flows out through the second steam chamber 12, due to the shorter flow path of the second steam chamber 12, the time for the steam to be heated after flowing out of the third steam chamber 13 is limited, so the temperature increase of the steam is relatively insignificant. Since the steam is ejected through the second steam nozzle 32, and not all of the steam nozzles (only some steam nozzles), the steam also has a relatively high ejection velocity. This operating mode can be called the low-temperature, high-steam-velocity mode (the operating state of the regulating valve 2 is as follows). Figure 8 and Figure 9 (As shown).

[0062] When steam flows out simultaneously from the first steam chamber 11 and the second steam chamber 12, this working mode can be called the large-area steam mode. Steam enters the steam channel 20 through the steam inlet 22, then enters the first steam chamber 11 through the first connecting hole 241, and the second steam channel 12 through the second connecting hole 242, finally exiting through all the steam nozzles (first steam nozzle 31 and second steam nozzle 32). In this working mode, the steam spray area is large, enabling rapid ironing over a large area, maximizing the area affected by the steam. In this working mode, low-temperature and high-temperature steam are mixed together to obtain medium-temperature, large-area steam (the operating state of the regulating valve 2 is as follows). Figure 6 and Figure 7 (As shown).

[0063] This application also provides a hair dryer. The hair dryer includes a housing and a heating assembly 100 as described in any of the above embodiments. The housing is provided with a first steam nozzle 31 and a second steam nozzle 32. The heating assembly 100 is installed inside the housing, such that the first steam chamber 11 of the heating assembly 100 can communicate with the first steam nozzle 31 on the housing, and the second steam chamber 12 of the heating assembly 100 can communicate with the second steam nozzle 32 on the housing.

[0064] In this ironing head, the steam heated by the heating component 100 can be ejected from the first steam nozzle 31, or from the second steam nozzle 32, or from both the first steam nozzle 31 and the second steam nozzle 32, depending on the amount, temperature and area of ​​the steam ejected, in order to meet different ironing needs.

[0065] In some exemplary embodiments, the first steam nozzle 31 may be configured to include more than one steam nozzle. The second steam nozzle 32 may be configured to include more than one steam nozzle. The number of steam nozzles included in the first steam nozzle 31 and the number of steam nozzles included in the second steam nozzle 32 may be set differently, so that the injection area of ​​steam flowing through the first steam chamber 11 is different from that flowing through the second steam chamber 12, thereby obtaining different injection velocities. Alternatively, the number of steam nozzles included in the first steam nozzle 31 and the number of steam nozzles included in the second steam nozzle 32 may be set to be the same, but the cross-section of each individual steam nozzle may be differentiated to achieve the technical effect of obtaining different injection velocities.

[0066] In some exemplary embodiments, the housing is further configured to include a first sub-housing and a second sub-housing. Specifically, the first steam nozzle 31 and the second steam nozzle 32 are both disposed on the second sub-housing.

[0067] The first part 18 of the heater 1 and the first sub-shell can be integrally molded, which effectively simplifies the design structure, reduces weight, simplifies the assembly process, avoids gaps after assembly, and also improves the sealing of the heating head, giving the heating head a better appearance. Of course, the first part 18 of the heater 1 and the first sub-shell can also be set as different parts.

[0068] In addition, such as Figure 5 As shown, the third part 15 of the heater 1 can also be integrally formed with the second sub-shell, which can effectively simplify the design structure, reduce weight, simplify the assembly process, avoid gaps after assembly, and improve the sealing of the heating head, giving the heating head a better appearance. Of course, the third part of the heater 1 and the second sub-shell can also be set as different parts.

[0069] In some exemplary embodiments, the housing is configured to have a first ironing area 41 and a second ironing area 42. For example... Figure 5 As shown, the first ironing area 41 and the second ironing area 42 are integrally formed on the second sub-shell with the third part 15 of the heater 1 (the two sides of the dashed line are the first ironing area 41 and the second ironing area 42 respectively). The first steam nozzle 31 is provided in the first ironing area 41 and the second steam nozzle 32 is provided in the second ironing area 42. The area sizes of the first ironing area 41 and the second ironing area 42 are set to be different.

[0070] By setting the first ironing area 41 where the first steam nozzle 31 is located and the second ironing area 42 where the second steam nozzle 32 is located to have different areas, when the first steam nozzle 31 sprays steam, the entire area of ​​the first ironing area 41 is sprayed with steam, and when the second steam nozzle 32 sprays steam, the entire area of ​​the second ironing area 42 is sprayed with steam, thus achieving different steam spraying areas.

[0071] It should be understood that the area of ​​the first ironing area 41 and the area of ​​the second ironing area 42 can also be set to be the same.

[0072] In some exemplary embodiments, the heating head also includes an adjustment knob (not shown). The adjustment knob can be mounted on the housing, such as on a first sub-housing. A portion of the adjustment knob is connected to the regulating valve 2, such as a portion of the adjustment knob being connected to the valve core 25 of the regulating valve 2, so that the valve core 25 connected to it can be actuated by operating the adjustment knob. For example, the adjustment knob can be toggled to achieve rotation of the valve core 25 relative to the valve body 24.

[0073] Setting an adjustment knob can improve operational comfort and enhance product design quality. Alternatively, position indicators can be placed around the adjustment knob to provide operators with more intuitive visual cues for controlling the regulating valve 2 and enabling steam to exit from different steam nozzles.

[0074] This application also provides an ironing device, which is an electric iron or a garment steamer. The ironing device includes the heating element 100 described in any of the above embodiments, or includes the ironing head described in any of the above embodiments.

[0075] When the ironing equipment is a garment steamer, the garment steamer includes a main unit (not shown in the figure) and an ironing head as described in any of the above embodiments. The main unit and the ironing head are connected by a steam pipe, which can be a rubber hose. The steam pipe can communicate with the inlet 181 of the first part 18 of the heating assembly 100, allowing steam generated by the main unit to enter the heating assembly 100 through the inlet 181 and be reheated within the heating assembly 100.

[0076] When the ironing device is an electric iron, the electric iron includes the heating component 100 described in any of the above embodiments. Water can enter the heating component 100 from the inlet 181 of the first part 18 of the heating component 100 and be heated into steam within the heating component 100.

[0077] The ironing device provided in this application includes the ironing head or heating component described in any of the above embodiments, and thus has all the beneficial effects of the ironing head or heating component described in any of the above embodiments, which will not be repeated here.
