Description

Technical Field

[0001] This utility model relates to the field of steam ironing technology, specifically to a steam ironing device with uniform temperature control. Background Technology

[0002] The main component of a steam iron is the steam generator, which contains heating elements. Several steam holes are located on the soleplate of the steam generator. To ensure a compact structure and maximize heat in the main ironing area, the heating elements are generally positioned closer to the rear of the soleplate. This results in higher temperatures closer to the heat source and lower temperatures further away. Furthermore, since the water tank's filling point is typically located at the front of the steam generator, water entering the generator or the generation of low-temperature steam at the front absorbs a significant amount of heat, lowering the temperature at the front of the soleplate. This causes the thermostat to continue heating, further widening the temperature difference between the front and rear of the soleplate. For example, if water vaporizes directly at the front of the steam generator, leaving no water at the rear, the rear of the generator will also overheat. Excessive temperature differences between the front and rear of the soleplate negatively impact ironing results, may damage clothing, and reduce ironing efficiency.

[0003] Therefore, the purpose of this application is to provide a steam ironing device with uniform temperature control that can solve at least one of the above problems. Summary of the Invention

[0004] Based on the above analysis, this utility model proposes a steam ironing device with uniform temperature control, which aims to solve at least one of the above technical problems.

[0005] This utility model is mainly achieved through the following technical solutions: This utility model provides a steam ironing device with uniform temperature control, including a soleplate assembly, a water storage container, a first control valve, and a second control valve; The base plate assembly is provided with a steam chamber and several steam outlets communicating with the steam chamber; the water storage container is provided with a first water outlet and a second water outlet respectively communicating with the front and rear of the steam chamber. The first control valve is movably installed on the first outlet. A first temperature-sensitive triggering structure is provided between the water storage container and the base plate assembly to cooperate with the first control valve. When the base plate assembly reaches the first temperature threshold, the triggering part of the first temperature-sensitive triggering structure deforms and acts on the first control valve to connect the first outlet with the front of the steam chamber. The second control valve is movably installed on the second outlet. A second temperature-sensitive triggering structure is provided between the water storage container and the base plate assembly to cooperate with the second control valve. When the base plate assembly reaches the second temperature threshold, the triggering part of the second temperature-sensitive triggering structure deforms and acts on the second control valve to connect the second outlet with the rear of the steam chamber. The second temperature threshold is greater than the first temperature threshold.

[0006] By setting a first control valve and a second control valve, and cooperating with the first temperature change triggering structure and the second temperature change triggering structure respectively, the temperature of the front and rear of the steam chamber is controlled in a zone. When the temperature of the base plate assembly reaches the first temperature threshold, water is released from the front of the steam chamber to generate steam. When the temperature rises further to the second temperature threshold, water is released from the rear of the steam chamber, thereby avoiding local overheating or uneven temperature, and improving the ironing effect and safety.

[0007] Furthermore, a heat insulation plate is provided between the water storage container and the base plate assembly. The heat insulation plate separates the water storage container from the base plate assembly, preventing heat from being conducted upwards. This allows the water in the water storage container to be preheated, enabling the temperature change triggering structure to more accurately obtain the temperature of the base plate assembly and avoiding false triggering.

[0008] Furthermore, the first and second temperature-change trigger structures are respectively installed between the base plate assembly and the insulation board. The installation position of the temperature-change trigger structure can quickly sense changes in the operating temperature of the base plate assembly, shorten the response time, and improve the real-time performance and accuracy of temperature control. The appropriate installation position can be selected according to different product structures.

[0009] Furthermore, at least one of the first and second water outlets is provided with a flow channel corresponding to and communicating with the steam chamber between it and the base plate assembly, and the first control valve and / or the second control valve are partially fitted into the corresponding flow channel, and the flow channel is selectively connected to the water storage container.

[0010] Furthermore, at least one of the first and second water outlets is provided with a flow channel corresponding to and communicating with the steam chamber between it and the base plate assembly. The first control valve and / or the second control valve are partially fitted into the corresponding flow channel. The flow channel is selectively connected to the water storage container, and the flow channel passes through the heat insulation plate.

[0011] Furthermore, the flow channel includes a first flow channel, and a first flexible sleeve is sealed between the water storage container and the bottom plate assembly to form the first flow channel. The first flexible sleeve is respectively in clearance fit with the first control valve and the trigger part of the first temperature change trigger structure. The first flexible sleeve is provided with a first water outlet pipe that communicates with the front part of the steam chamber. And / or, the flow channel includes a second flow channel, and a second flexible sleeve is sealed between the water storage container and the bottom plate assembly to form a second flow channel. The second flexible sleeve is respectively fitted with the trigger part of the second control valve and the second temperature-sensitive triggering structure. The second flexible sleeve is provided with a second water outlet pipe that communicates with the rear part of the steam chamber.

[0012] The flexible sleeve integrates multiple functions such as dynamic sealing, force transmission, and flow channel formation. It physically isolates the water circuit from mechanical components such as the temperature-sensitive triggering structure, guides water from the water storage container to the bottom plate assembly, reduces the temperature of the bottom plate assembly, and allows the bottom plate assembly to preheat the water in the flexible sleeve before it enters the steam chamber, thereby improving vaporization efficiency, extending the service life of the temperature-sensitive triggering structure, reducing the layout of external pipelines, and simplifying the structure.

[0013] Furthermore, both the first control valve and the second control valve are mechanical control valves. The mechanical control valve includes a valve stem and a valve core mounted on the valve stem. The valve stem passes through the water storage container and is partially located in the flow channel. The valve core is movably sealed to the first outlet and the second outlet, respectively.

[0014] Furthermore, the mechanical control valve also includes an elastic element, one end of the valve stem is provided with a limiting part that is disposed opposite to the valve core, and the elastic element is disposed between the water storage container and the limiting part; The triggering part of the first temperature-sensitive triggering structure acts on the corresponding limiting part through the first flexible sleeve; And / or, the triggering part of the second temperature-sensitive triggering structure acts on the corresponding limiting part via the second flexible sleeve.

[0015] Mechanical control valves are easy to maintain and low in cost. Even if the temperature-triggered structure fails, they can still ensure that the outlet is closed to prevent continuous leakage and improve the safety of use.

[0016] Furthermore, the bottom of the first flexible sleeve is located between the trigger part and the corresponding limiting part of the first temperature-sensitive triggering structure, and there are gaps between the bottom of the first flexible sleeve and the trigger part and the corresponding limiting part of the first temperature-sensitive triggering structure, respectively; and / or, the bottom of the second flexible sleeve is located between the trigger part and the corresponding limiting part of the second temperature-sensitive triggering structure, and there are gaps between the bottom of the second flexible sleeve and the trigger part and the corresponding limiting part of the second temperature-sensitive triggering structure, respectively. This not only avoids accidental triggering of the control valve during installation, but also ensures that when the trigger part deforms due to heat, it can trigger the corresponding flexible sleeve to deform and contact the limiting part, causing the valve stem to drive the valve core to move vertically and open the water outlet.

[0017] Furthermore, both the first and second temperature-sensitive trigger structures are double-layer metal sheets, which have fast response speeds and low costs.

[0018] Furthermore, the front part of the steam chamber is provided with a first through hole corresponding to and communicating with the first water outlet, and the rear part of the steam chamber is provided with a second through hole corresponding to and communicating with the second water outlet.

[0019] Furthermore, the diameter of the first through hole is different from the diameter of the second through hole.

[0020] By differentiating the diameter of the through holes in the front and rear parts of the steam chamber, the cooling rate and steam generation in the front and rear areas can be precisely controlled. Furthermore, the size of the second through hole can be adjusted as needed to ensure that the steam does not drip water. By increasing the diameter of the second through hole, the water flow rate can be increased, allowing the temperature at the front and rear ends of the base plate assembly to quickly reach equilibrium.

[0021] Compared with existing technologies, the steam ironing device with uniform temperature control provided by this utility model has the following advantages: By setting a first temperature-sensitive trigger structure and a second temperature-sensitive trigger structure between the soleplate assembly and the water storage container, when the rear temperature of the soleplate assembly becomes too hot, the second temperature-sensitive trigger structure deforms and triggers the second control valve, which connects the second water outlet to the steam chamber. By increasing the number of water injection points and automatically discharging water when the set temperature threshold is reached, the rear temperature of the soleplate assembly is reduced, making the temperature of the soleplate assembly more uniform, thus ensuring ironing effect and efficiency, and making it more convenient to use.

[0025] To enable those skilled in the art to better understand this utility model and to more clearly define the scope of protection claimed by this utility model, the present utility model is described in detail below with reference to certain specific embodiments. It should be noted that the following are only some specific embodiments of the present utility model, and the specific and direct descriptions of related structures are merely for the convenience of understanding the present utility model; the specific features do not necessarily or directly limit the scope of implementation of the present utility model. Conventional choices and substitutions made by those skilled in the art under the guidance of the present utility model should all be considered within the scope of protection claimed by this utility model.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0027] Example 1 like Figure 1-2 As shown in Figure 4, this utility model provides a steam ironing device with uniform temperature control, including a soleplate assembly 1, a water storage container 2, a first control valve 3, and a second control valve 4. The soleplate assembly 1 is provided with a steam chamber 1a and several steam outlets communicating with the steam chamber 1a; the water storage container 2 is provided with a first water outlet 2a and a second water outlet 2b respectively communicating with the front and rear of the steam chamber 1a. The first temperature change triggering structure 5 and the second temperature change triggering structure 6 are double-layered metal sheets.

[0028] like Figure 5-6As shown, the first control valve 3 is movably installed on the first outlet 2a. A first temperature-sensitive triggering structure 5 is provided between the water storage container 2 and the base plate assembly 1, which is movably coordinated with the first control valve 3. When the base plate assembly 1 reaches the first temperature threshold, the triggering part of the first temperature-sensitive triggering structure 5 deforms and acts on the first control valve 3 to open the first outlet 2a, so that the first outlet 2a is connected to the front of the steam chamber 1a. When the base plate assembly 1 is below the first temperature threshold, the triggering part of the first temperature-sensitive triggering structure 5 resets and stops applying force to the first control valve 3, and the first control valve 3 and the first outlet 2a are in a sealed state.

[0029] The second control valve 4 is movably mounted on the second outlet 2b. A second temperature-sensitive triggering structure 6, which movably engages with the second control valve 4, is provided between the water storage container 2 and the base plate assembly 1. When the base plate assembly 1 reaches the second temperature threshold, the triggering part of the second temperature-sensitive triggering structure 6 deforms, causing the second control valve 4 to open the second outlet 2b, thus connecting the second outlet 2b to the rear of the steam chamber 1a. When the temperature of the base plate assembly 1 is below the second temperature threshold, the triggering part of the second temperature-sensitive triggering structure 6 resets, ceasing the application of force to the second control valve 4, and the second control valve 4 and the second outlet 2b are in a sealed state. The second temperature threshold is greater than the first temperature threshold. When the base plate assembly 1 reaches the second temperature threshold, the first control valve 3 remains open.

[0030] The first outlet 2a and the second outlet 2b are respectively provided with flow channels 8 that are connected to the steam chamber 1a between the bottom plate assembly 1 and the first control valve 3 and the second control valve 4 respectively in the corresponding flow channels 8. The flow channels 8 can be selectively connected to the water storage container 2.

[0031] In some embodiments, the flow channel 8 is disposed between the first water outlet 2a and the front part of the steam chamber 1a.

[0032] In another embodiment, the flow channel 8 is disposed between the second water outlet 2b and the rear of the steam chamber 1a.

[0033] like Figure 3 As shown, the flow channel 8 includes a first flow channel 81 and a second flow channel 82. A first flexible sleeve 9 is sealed between the water storage container 2 and the bottom plate assembly 1 to form the first flow channel 81. The first flexible sleeve 9 is in clearance fit with the trigger part of the first control valve 3 and the first temperature change trigger structure 5 respectively. The first flexible sleeve 9 is provided with a first water outlet pipe 91 that communicates with the front part of the steam chamber 1a.

[0034] A second flexible sleeve 10 is provided between the water storage container 2 and the bottom plate assembly 1 to form a second flow channel 82. The second flexible sleeve 10 is respectively fitted with the trigger part of the second control valve 4 and the second temperature change trigger structure 6. The second flexible sleeve 10 is provided with a second water outlet pipe 101 that communicates with the rear part of the steam chamber 1a.

[0035] By cooperating with the control valve, the first flexible sleeve 9 and the second flexible sleeve 10 form a sealed flow channel, which not only ensures the sealing of the water flow channel, but also transmits the action of the temperature change trigger structure through the deformation of the flexible material, so as to achieve precise control of the mechanical valve. The structure is simple, low in cost and highly reliable.

[0036] like Figure 5-6 As shown, both the first control valve 3 and the second control valve 4 are mechanical control valves. Each mechanical control valve includes a valve stem 11 and a valve core 12 mounted on the valve stem 11. The valve stem 11 passes through the corresponding outlet on the water storage container 2 and is partially located within the flow channel 8. The valve core 12 is movably sealed to the first outlet 2a and the second outlet 2b, respectively. The mechanical control valve also includes an elastic element 13. One end of the valve stem 11 is provided with a limiting part 111 opposite to the valve core 12. The elastic element 13 is disposed between the water storage container 2 and the limiting part 111. The elastic element 13 can be disposed within the water storage container 2 or within the flow channel 8.

[0037] like Figure 5-7 As shown, a heat insulation plate 7 is also provided between the water storage container 2 and the base plate assembly 1, and a flow channel 8 passes through the heat insulation plate 7. A first flexible sleeve 9 is installed at the front of the heat insulation plate 7, and a second flexible sleeve 10 is installed at the rear of the heat insulation plate 7. The first flexible sleeve 9 and the second flexible sleeve 10 are engaged between the water storage container 2 and the heat insulation plate 7, and partially pass through the heat insulation plate 7. The first flexible sleeve 9 and the second flexible sleeve 10 are silicone sleeves, and the bottom of the first flexible sleeve 9 and the second flexible sleeve 10 has a protrusion that is clearance-fitted with the free end of the double-layer metal sheet. A first temperature change triggering structure 5 and a second temperature change triggering structure 6 are respectively installed between the base plate assembly 1 and the heat insulation plate 7.

[0038] In this embodiment, the first flexible sleeve 9 and the second flexible sleeve 10 are separately disposed from the valve stem 11. In another embodiment, the first flexible sleeve 9 and the second flexible sleeve 10 are integrally formed with the valve stem 11 and are made of silicone, which facilitates installation and disassembly.

[0039] The triggering part of the first temperature-sensitive triggering structure 5 acts on the corresponding limiting part 111 via the first flexible sleeve 9, and the triggering part of the second temperature-sensitive triggering structure 6 acts on the corresponding limiting part 111 via the second flexible sleeve 10.

[0040] In another embodiment, the triggering part of the first temperature-sensitive triggering structure 5 and the triggering part of the second temperature-sensitive triggering structure 6 can also be fitted with the first control valve 3 and the second control valve 4, which are respectively sealed at the bottom and pass through the flow channel 8. When the triggering part deforms, it drives the bottom of the first control valve 3 and the second control valve 4, causing the bottom of the corresponding flexible sleeve to move upward synchronously, thereby opening the corresponding water outlet.

[0041] like Figure 2 ,3 As shown, the base plate assembly 1 includes a base plate 14 and an upper cover 15 that are connected to each other, and the water storage container 2 includes an upper shell 21 and a lower shell 22 that are connected to each other. One end of the double-layer metal sheet is installed on the upper surface of the base plate assembly 1, and the other end is located below the protrusions of the first flexible sleeve 9 and the second flexible sleeve 10. The first flexible sleeve 9 and the second flexible sleeve 10 are engaged between the lower shell 22 and the heat insulation plate 7.

[0042] The front of the steam chamber 1a is provided with a first through hole 1b corresponding to and communicating with the first water outlet 2a, and the rear of the steam chamber 1a is provided with a second through hole 1c corresponding to and communicating with the second water outlet 2b. The diameter of the first through hole 1b is different from the diameter of the second through hole 1c. The first through hole 1b and the second through hole 1c are provided on the upper cover 15. The first water outlet pipe 91 is provided on the first through hole 1b, and the second water outlet pipe 101 is provided on the second through hole 1c. The diameter of the first through hole 1b is larger than the diameter of the second through hole 1c. Among them, the water outlet diameter of the first water outlet pipe 91 is larger than the water outlet diameter of the second water outlet pipe 101.

[0043] like Figure 3 , 5 As shown in Figure -6, the bottom of the first flexible sleeve 9 is located between the triggering part of the first temperature-sensitive triggering structure 5 and the corresponding limiting part 111. In its natural state, there are gaps between the bottom of the first flexible sleeve 9 and the triggering part of the first temperature-sensitive triggering structure 5 and the corresponding limiting part 111. And / or, the bottom of the second flexible sleeve 10 is located between the triggering part of the second temperature-sensitive triggering structure 6 and the corresponding limiting part 111. There are gaps between the bottom of the second flexible sleeve 10 and the triggering part of the second temperature-sensitive triggering structure 6 and the corresponding limiting part 111. In this embodiment, the first temperature threshold is 130-160℃. When the temperature of the base plate assembly 1 is greater than 130℃, the double-layer metal sheet will bounce upward and press against the limiting part 111 of the valve stem 11, causing the valve core 12 to move upward and away from the first outlet 2a. The water storage container 2 is connected to the front of the steam chamber 1a through the first outlet 2a and the first flow channel 81. When the temperature of the base plate assembly 1 is less than 130℃ (specifically between 95-120℃), the double-layer metal sheet will automatically spring back downwards and leave a gap with the bottom of the first flexible sleeve 9, so that the valve core 12 is reset under the action of the elastic element 13 to seal the first outlet 2a.

[0044] The second temperature threshold is 200-210℃. When the temperature of the base plate assembly 1 is greater than 200℃ (specifically between 180-190℃), the double-layer metal sheet will bounce upwards and press against the bottom of the second flexible sleeve 10 and the limiting part 111 of the valve stem 11, causing the valve core 12 to move upwards away from the second outlet 2b. The water storage container 2 is connected to the rear of the steam chamber 1a through the second outlet 2b and the second flow channel 82. When the temperature of the base plate assembly 1 is less than 200℃, the double-layer metal sheet will automatically bounce downwards and leave a gap with the bottom of the second flexible sleeve 10, allowing the valve core 12 to reset under the action of the elastic element 13 to seal the second outlet 2b.

[0045] The range of the first temperature threshold and the range of the second temperature threshold can be manually set according to actual needs. The double-layer metal sheet undergoes elastic deformation due to temperature changes, causing the first control valve 3 and the second control valve 4 to open or close. When open, the elastic deformation of the double-layer metal sheet can be either opening or contracting. When no external force is applied, a gap remains between the limiting part 111 and the inner surfaces of the first flexible sleeve 9 and the second flexible sleeve 10.

[0046] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
