Description

Technical Field

[0001] This utility model relates to the technical field of heating components for handheld garment steamers, specifically to a dual-channel U-shaped cast aluminum heating element structure for a handheld garment steamer. Background Technology

[0002] A garment steamer is a machine that softens the fibers of clothing by continuously contacting it with hot steam. Through "pulling" and "pressing" motions, it smooths and flattens the garments. The hot steam also has a cleaning and disinfecting effect. Suitable for clothing stores, hotels, and homes, it only requires adding water and turning on the power for 30 seconds to spray high-pressure steam. Simply spray the steam onto the wrinkles of the garment to make it smooth and soft. No ironing board is needed, eliminating the tedious steps of traditional ironing. The product is suitable for ironing and disinfecting clothing, curtains, and carpets of any material. It is simple to use, convenient to operate, and saves energy and time.

[0003] Most existing handheld garment steamers use a cast aluminum heating element with a single cavity and single flow channel design. Its working principle is as follows: water enters the heating cavity through a single inlet and flows along a fixed path. The thermal conductivity of cast aluminum heats the water, causing it to gradually vaporize and generate steam, providing the steam source for the garment steamer. Structurally, it typically consists of a cast aluminum cavity, a single inlet, and a heating element (integrated with the cast aluminum cavity). The water flows unidirectionally through the heating area within the cavity to complete vaporization.

[0004] Due to the single-channel design, the water flow distribution within the single cavity is uneven, resulting in insufficient heat exchange. This makes it difficult for all water flows to efficiently absorb heat and complete phase change. The water flow is concentrated and follows a fixed path, leading to insufficient heat absorption in some areas, which prevents complete vaporization and causes liquid water to be ejected with steam, a phenomenon known as "water spraying." In the single-channel structure, the fixed water flow path easily creates "water flow blind spots." The channel design fails to disperse the water flow and balance heat exchange, preventing heat from being effectively carried away through water circulation. This results in localized continuous heating of the cast aluminum cavity without water cooling, causing localized high temperatures. Long-term operation not only affects the lifespan of the heating element but may also pose safety risks due to excessively high temperatures. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a dual-channel U-shaped cast aluminum heating element structure for a handheld garment steamer, which can effectively solve the problems mentioned in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a dual-channel U-shaped cast aluminum heating element structure for a handheld garment steamer, comprising: a cast aluminum heating element body, the cast aluminum heating element body including a bottom plate, a top plate and a sealing cover, the bottom plate and the top plate being sealed together, the top plate and the sealing cover being sealed together, and interfaces being fixedly connected to both sides of the bottom end of the cast aluminum heating element body, the interfaces being connected to the water and electrical systems of the garment steamer.

[0007] Furthermore, a water inlet is provided at the bottom of the base plate, and an independent flow channel is provided inside the base plate.

[0008] Furthermore, the independent flow channel has a U-shaped design, with the inlet located in the middle of the top of the independent flow channel.

[0009] Furthermore, several first baffles are uniformly arranged on the inner wall surface of the independent flow channel, and the first baffles are staggered inside the independent flow channel.

[0010] Furthermore, a manifold is provided in the middle of the base plate, which is connected to an independent flow channel, and a partition is fixedly connected in the middle of the manifold.

[0011] Furthermore, a secondary heating channel is provided inside the top plate, and several second baffles are provided on the inner wall of the secondary heating channel. The second baffles are distributed alternately inside the secondary heating channel.

[0012] Furthermore, a through hole is provided in the middle of the top plate, and the through hole is connected to the manifold.

[0013] The technical solution provided by this utility model has the following advantages compared with the known prior art: 1.

Compared to a single flow channel, the heat exchange area and efficiency are greatly improved, solving the problem of water spraying at its source. The steam output is more stable and the dryness is higher, meeting the high-efficiency ironing requirements of garment steamers. 2.

Compared with the local high temperature risk of traditional single-channel flow, this design can reduce the thermal stress of the cavity, extend the service life of the heating element, and improve the stability and safety of the equipment. 3. By simply optimizing the design of the heating element flow channel and water inlet, without the need for complex additional components such as adding a heating element, it can be compatible with the assembly logic of existing handheld garment steamers, facilitating mass production and market promotion, and achieving performance breakthroughs through low-cost structural innovation.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] The present invention will be further described below with reference to the embodiments. Example 1:

[0019] Reference Figure 1-4 This is the first embodiment of the present invention, which discloses a dual-channel U-shaped cast aluminum heating element structure for a handheld garment steamer, comprising: a cast aluminum heating element body 1, the cast aluminum heating element body 1 including a bottom plate 101, a top plate 102 and a sealing cover 103, the bottom plate 101 and the top plate 102 being sealed together, the top plate 102 and the sealing cover 103 being sealed together, and interfaces 2 being fixedly connected to both sides of the bottom end of the cast aluminum heating element body 1, the interfaces 2 being connected to the water and electrical systems of the garment steamer.

[0020] By simply optimizing the heating element flow channel and water inlet 1011 design, without the need for complex additional components such as adding heating elements, it can be compatible with the assembly logic of existing handheld garment steamers, facilitating mass production and market promotion, and achieving performance breakthroughs through low-cost structural innovation. Example 2:

[0021] Reference Figure 1-4 This is the second embodiment of the present invention, which differs from the first embodiment in that: The bottom end of the base plate 101 is provided with an inlet 1011, and an independent flow channel 1012 is provided inside the base plate 101. The independent flow channel 1012 is U-shaped. The inlet 1011 is located in the middle of the top of the independent flow channel 1012. Several first baffles 1013 are evenly arranged on the inner wall surface of the independent flow channel 1012. The first baffles 1013 are staggered inside the independent flow channel 1012. A confluence cavity 1014 is provided in the middle of the base plate 101. The confluence cavity 1014 is connected to the independent flow channel 1012. A partition 1015 is fixedly connected in the middle of the confluence cavity 1014.

[0022] With the water inlet 1011 and dual independent flow channels 1012, the water flow is evenly distributed and heated synchronously during use. Compared with a single flow channel, the heat exchange area and efficiency are greatly improved, solving the water spraying problem at its source. The steam output is more stable and the dryness is higher, meeting the high-efficiency ironing needs of garment steamers.

[0023] The top plate 102 has a secondary heating channel 1021 inside. The inner wall of the secondary heating channel 1021 is provided with a number of second baffles 1022. The second baffles 1022 are staggered inside the secondary heating channel 1021. The top plate 102 has a through hole 1023 in the middle, and the through hole 1023 is connected to the confluence cavity 1014.

[0024] By using a dual-flow water system to evenly remove heat and combining it with a reverse reheating process, the cast aluminum cavity is heated more evenly, avoiding heat accumulation. Compared to the risk of localized high temperatures in traditional single-flow systems, this design reduces thermal stress in the cavity, extends the lifespan of the heating element, and improves equipment stability and safety.

[0025] The remaining structure is the same as that in Example 1.

[0026] The workflow of this utility model is as follows: First, the water inlet 1011 is connected to the external connector. Water is evenly distributed into the independent flow channel 1012 cavity of the heating element through the external connector. The water flows fully exchange heat with the cast aluminum heating element in their respective flow channels and vaporizes quickly. With the setting of the water inlet 1011 and the dual independent flow channels 1012, the water flow is evenly distributed and heated synchronously during use. Compared with a single flow channel, the heat exchange area and efficiency are greatly improved, solving the water spraying problem from the root. The steam output is more stable and the dryness is higher, meeting the high-efficiency ironing requirements of the garment steamer. Secondly, the two steam streams converge in the manifold 1014 and flow in the opposite direction through the through hole 1023, passing through the back of the heating element and entering the secondary heating channel 1021. The steam absorbs heat again to complete deep vaporization and finally outputs efficient and stable steam. The heat is carried away evenly by the two water streams. Combined with the process of reheating in the opposite direction, the cast aluminum cavity is heated more evenly, avoiding heat accumulation. Compared with the local high temperature hazard of the traditional single flow channel, this design can reduce the thermal stress of the cavity, extend the service life of the heating element, and improve the stability and safety of the equipment. Finally, steam enters the handheld garment steamer through interface 2 and is ejected. By optimizing the design of the heating element flow channel and water inlet 1011, no complex additional components are needed, such as adding a heating element. This allows it to be compatible with the assembly logic of existing handheld garment steamers, facilitating mass production and market promotion. Performance breakthroughs are achieved through low-cost structural innovation.

[0027] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model 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 of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
