[0046] 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 will be described in detail below with reference to certain specific embodiments.
[0047] like Figure 1 As shown, an iron structure 100 is used as an electric iron for ironing clothes.
[0048] The iron structure includes an upper cover 101, a middle plate 103, and a bottom plate 104. The bottom plate 104 is installed at the lower end of the middle plate 103, and the upper cover 103 is installed at the upper end of the middle plate 103, so that the three are installed in a top-middle-bottom sequence. Among them, a first chamber is provided between the upper cover 101 and the middle plate 103 for a water tank structure 30 to be installed therein, and a second chamber is provided between the middle plate 103 and the bottom plate 104 for a steam generating structure 20 to be installed therein.
[0049] Preferably, a handle 102 is provided on the upper cover 101 for the user to hold; and the steam generating structure 20 is embedded in the interior of the middle plate 103 (i.e., the sides of the steam generating structure 20 are surrounded by the middle plate 103), such as Figure 4 As shown, the steam generating structure 20 is designed to be internally mounted to prevent burns and heat loss.
[0050] like Figure 1 As shown, two steam base plates are provided on the bottom surface of the base plate 104, namely the first steam base plate 111 and the second steam base plate 112. A base plate partition 113, for example, a groove shape, is provided between the first steam base plate 111 and the second steam base plate 112. Furthermore, base plate steam holes 108 are provided on the first steam base plate 111 and the second steam base plate 112 respectively, for steam to be discharged from them for ironing.
[0051] Preferably, in this embodiment, the first steam soleplate 111 and the second steam soleplate 112 are arranged front to back in the iron structure, allowing the iron structure to provide different ironing temperatures at its front and rear ends. Of course, it is also feasible to set both to the same steam temperature; that is, by arranging a steam zone along both the front and rear, the iron structure can have different ironing temperatures at the front and rear, or the same or different steam volume when the front and rear steam zone temperatures are the same, to meet ironing requirements. In other embodiments, the first steam soleplate 111 and the second steam soleplate 112 can also be arranged side to side or inside to outside, etc., and are not limited; they can be set as needed. For ordinary users, a front-to-back arrangement is the best implementation, as this allows the first steam soleplate 111 at the front to provide a higher steam temperature or steam volume. This aligns with the usage habit of general users who use the tip of the iron at the front of the iron to iron areas requiring focused ironing, thus improving the user experience.
[0052] like Figure 2 As shown, a first steam chamber 251 and a second steam chamber 252 are correspondingly provided on the bottom surface of the steam generating structure 20. These two chambers are separated by a first steam chamber arm 253 into two independent chambers that are not directly connected. A first steam outlet 254 is provided on the first steam chamber 251, and a second steam outlet 255 is provided on the second steam chamber 252. Figure 3 As shown, a third steam chamber groove 105 and a fourth steam chamber groove 106 are correspondingly provided on the upper surface of the base plate 104, and the two are separated by a second steam chamber arm 107. After the base plate 104 is installed with the steam generating structure 20, the first steam chamber groove 251 corresponds to and communicates with the third steam chamber groove 105 to form a first steam chamber 20a, and the second steam chamber 202 corresponds to and communicates with the fourth steam chamber 106 to form a second steam chamber 20b. Figure 4As shown, steam discharged from the first steam outlet 254 and the first steam outlet 205 can be discharged from the respective steam holes 108 of the first steam base plate 111 and the second steam base plate 112 for ironing. A third convex wall 109 is provided on the upper surface of the base plate 104 and arranged in a surrounding manner to form a third steam cavity groove 105 and a fourth steam cavity groove 106. The third convex wall 109 is also used for mounting the paper roll at the bottom surface of the steam generating structure 20, for example, by clipping it in place. Preferably, the first steam base plate 111 and the second steam base plate 112 each have multiple steam holes 108, and the multiple steam holes 108 are arranged in a straight line, an arc, or an array, which can be configured as needed. The first steam cavity arm 253 and the second steam cavity arm 107 form a partition wall 20c to separate the first steam cavity 20a and the second steam cavity 20b.
[0053] It should be noted that, although in this embodiment, the first steam cavity 20a and the second steam cavity 20b are each formed by two steam cavity slots that are interlocked vertically, in other embodiments, one steam cavity slot can be formed by another flat plate component, which can also achieve the formation of a relatively closed cavity space after assembly; in other words, the shape and formation of the first steam cavity 20a and the second steam cavity 20b are not limited to those shown in 1-4, and can also be other shapes or structures that achieve the same function.
[0054] like Figure 5-7 As shown, the steam generating structure 20 in this embodiment is a steam generating structure with two zones, that is, it can provide a high-temperature steam zone and a low-temperature steam zone, where high temperature and low temperature refer to relative temperature.
[0055] like Figure 6 As shown, the steam generating structure 20 includes a heat spreader 201 and a steam cover plate 202 mounted on the heat spreader 201, forming two mutually isolated vaporization chambers, namely a first vaporization chamber 221 and a second vaporization chamber 222. The heat spreader 201 is made of a thermally conductive material, the specific material being selected as needed. A heating element mounting portion 2012 is provided on the heat spreader 201, and the heating element 200 is internally mounted within the heating element mounting portion 2012. The first vaporization chamber 221 is located within... The second vaporization chamber 222 is located on the outer side and / or inner side of the heating element mounting part 2012, so that the first vaporization chamber 221 is in direct contact with the side wall of the heating element mounting part 2012 for heat exchange, and the second vaporization chamber 222 is heat exchanged through the heat exchanger 201 for heat conduction. That is, the heating of the first vaporization chamber 221 by the heating element 200 is stronger than its heating of the second vaporization chamber 222, resulting in a higher steam temperature in the first vaporization chamber 221.
[0056] like Figure 5As shown, a temperature control device 204 is installed on the steam generating structure 20 to control the working state of the heating element 200, such as adjusting the temperature or heating level of the heating element 200. The temperature control device 204 is fixedly installed at the installation position 203 of the steam generating structure 20 by mounting screws 205.
[0057] like Figure 2 , 4 As shown in Figure 6, in this embodiment, the heat spreader 201 has a plate layer 2011. First convex walls 2014, arranged in a ring around the upper surface of the plate layer 2011, are respectively protruding. A generally V-shaped heating element mounting portion 2012 is formed within the enclosure of the first convex walls 2014 and is formed on the upper surface of the plate layer 2011. A second convex wall 2015 protrudes from the top surface of the heating element mounting portion 2013, and the second convex wall 2015 is formed as a closed type. The structure is designed to form a first vaporization chamber 221; cavity ends 2013 are provided at both ends of the heating element mounting part 2012, and a notch 2016 is formed between the second convex wall 2015 and the first convex wall 2014 near the cavity end 2013. Since the heating element mounting part 2012 is V-shaped, the two spaces located on the inner and outer sides of the heating element mounting part 2012 can be interconnected through the notch 2016, thereby forming a second vaporization chamber 222 that is interconnected in all parts.
[0058] like Figure 6 As shown, a first end 211, a second end 212, a third end 214, and a fourth end 215 are provided on the steam cover plate 202. The first end 211 and the second end 212 pass through the steam cover plate 202 and communicate with the first vaporization chamber 221. The third end 214 and the fourth end 215 pass through the steam cover plate 202 and communicate with the second vaporization chamber 222. Furthermore, a first pipe 213 and a second pipe 216 are respectively connected to the second end 212 and the fourth end 215. The first pipe 213 connects the second end 212 to the first steam outlet 254 to input the steam generated by the first vaporization chamber 221 into the first steam chamber 20a. The second pipe 216 connects the fourth end 215 to the second steam outlet 255 to input the steam generated by the second vaporization chamber 222 into the second steam chamber 20b, thereby realizing independent steam generation in two zones. The first pipe 213 and the second pipe 216 are respectively provided with a first pipe end 206 and a second pipe end 207. The first pipe end 206 is connected to the first steam outlet 254 and the second pipe end 207 is connected to the second steam outlet 255.
[0059] Although the heating element mounting part 2012 in this embodiment is generally V-shaped, it is not difficult to see from the above structure and working principle that other shapes are also feasible, such as U-shaped or Ω-shaped.
[0060] like Figure 6As shown, in this embodiment, although the first vaporization chamber 221 can contact the heating element 200 and easily increase its steam temperature, its area is relatively smaller, so the amount of steam generated is small and the temperature is high. The second vaporization chamber 222 is the opposite, that is, due to its large area and uniform heat conduction, its steam volume is large and its temperature is low.
[0061] like Figure 7 As shown, the first vaporization chamber 221 is composed of a first chamber 2211, a second chamber 2212, and a third chamber 2213 connected end to end in sequence. A third connecting position 2214 is provided at the beginning of the first chamber 2211, and a fourth connecting position 2214 is provided at the end of the third chamber 2213. The second vaporization chamber 222 is composed of a fourth chamber 2221, a fifth chamber 2222, and a sixth chamber 2223. The fourth chamber 2221 is located inside the V-shaped heating element mounting part 2012, and there are two sixth chambers 2223 located outside the heating element mounting part 2012. The fifth chamber 2222 is located at the notch 2016 to cross the heating element mounting part 2012.
[0062] like Figure 7-8 As shown, in this embodiment, the first end 211 is positioned inside the heating element mounting portion 2012 and communicates with the second vaporization chamber 222, i.e., it is positioned at the first communication position 2224. The second end 212 is positioned inside the heating element mounting portion 2012, i.e., it is positioned at the second communication position 2225, so that the second vaporization chamber 222... Figure 7 The water vapor flows in the direction indicated by the dashed arrow, starting at the upper middle position of the heat spreader 201, then moving downwards until it splits into two streams near the lower end. These streams then move upwards along both sides until they exit the second vaporization chamber 222 at the second connecting position 2225, located at the upper part of the heat spreader 201. Therefore, the water vapor in the second vaporization chamber 222 follows a heart-shaped path. The water vapor in the first vaporization chamber 221 flows in a significantly different direction. It starts at the third connecting position 2214, which is close to the middle of the heating element 200, and then moves along one side of the heating element 200. Near one end of the heating element 200, it makes a 180° turn and then moves in the opposite direction along the path of the heating element 200 until it exits at the fourth connecting position 2215, near the other end of the heating element 200. Figure 7 As indicated by the dashed arrow, the first vaporization chamber 221 runs along a similar "Z" shaped path.
[0063] like Figure 9-13As shown, in this embodiment, the water tank structure 30 includes a distribution valve 31, a pump 32, and a water tank 33. The distribution pump 31 and the pump 32 are installed between the water tank 33 and the steam generating structure 20, so that water in the water tank 33 can be pumped into the first vaporization chamber 221 and / or the second vaporization chamber 222 of the steam generating structure 20 as needed. That is, water can be pumped into one of the two or into both at the same time, which can be controlled as needed.
[0064] The pump component 32 includes a pump body 321, an inlet pipe 322, and an outlet pipe 323. One end of the inlet pipe 322 is connected to the inlet end of the pump body 321, and the other end is connected to the water tank 33 via a water tank connector 324. The outlet pipe 323 is connected between the outlet end of the pump body 321 and the first connector 312 of the distribution valve component 31, thereby pumping water from the water tank 33 into the distribution valve component 31.
[0065] The distribution valve 31 includes a valve body 311, a first connector 312, a second connector 313, and a third connector 314. The second connector 313 and the third connector 314 are respectively disposed on the left and right sides of the first connector 312. The second connector 313 is connected to the first end 211 via a first pipe 301, and the third connector 314 is connected to the third end 214 via a second pipe 302. That is, the first pipe 301 and the second pipe 302 are respectively provided with a third pipe end 303 and a fourth pipe end 304 for connecting to the first end 211 and the third end 214, respectively. Furthermore, a distribution valve cavity 315 is provided inside the valve body 311, and a valve stem 316 is movably disposed inside the distribution valve cavity 315. The distribution valve cavity 315 is formed into a closed structure on one side, for example, in this embodiment, it is a closed structure at the right end. The valve stem 316 includes a stem portion 317 and a first sealing portion 318 and a second sealing portion 319 located on the left and right sides of the stem portion 317. The valve stem 316 moves within the distribution valve chamber 315 to form a first state, a second state, and a third state, corresponding to the three working states of the distribution valve 31. In the first state, both the first sealing part 318 and the second sealing part 319 are located to the left of the second connector 313. At this time, the first connector 312 is simultaneously connected to both the second connector 313 and the third connector 314, meaning the distribution valve 31 is in a working state where water is being pumped into both vaporization chambers simultaneously. In the second state, the first sealing part 318 is located to the left of the second connector 313, and the second sealing part 319 is located to the left of the second connector 313. 19 is located between the first connector 312 and the second connector 313, so that the first connector 312 is only connected to the third connector 314. The distribution valve 31 is in a working state where water is pumped into the first vaporization chamber 221 only. In the third state, the second sealing part 319 is located to the right of the third connector 314, and the first sealing part 318 is located between the first connector 312 and the third connector 314, so that the first connector 312 is only connected to the second connector 313. The distribution valve 31 is in a working state where water is pumped into the second vaporization chamber 222 only. The left and right displacement control of the valve stem 316 can be achieved by providing a push rod 320 exposed on the upper cover 101 on the valve stem 316. This push rod 320 is located in the first state position 341, the second state position 342, and the third state position 343 in the three states, respectively. Figure 10 As shown, push rod 320 is pushed left and right as it is adjusted between the three states.
