Technical Field

[0001] The present application relates to the technical field of irons, and in particular to an electric iron with a cooling function. Background Art

[0002] Electric irons are primarily used to iron clothes and smooth out wrinkles. During ironing, the heating wire inside the iron heats the soleplate, which then moves across the clothes to iron them. When ironing is complete, the iron is placed upright to allow the soleplate to cool naturally.

[0003] In related technology, Chinese utility model patent publication number CN205917508U discloses a rapidly cooling electric iron comprising an iron body and a base for the iron body. The base has a cavity disposed below the iron body, within which a cooling fan is located. An air inlet is provided at the bottom of the base, communicating with the cavity. An air outlet is provided at the top surface of the base, also communicating with the cavity. A foot is provided at the bottom of the base to support the base. The provision of a cooling fan on the base allows for rapid cooling of the iron body.

[0004] With respect to the above-mentioned related technologies, when cooling the iron, the iron needs to be placed on the base and used in conjunction with the base so that the heat dissipation fan can cool the iron. However, the provision of the base increases the space occupied by the iron. Summary of the Invention

[0005] In order to improve the cooling effect of the iron without changing the space occupancy of the iron, the present application provides an electric iron with a cooling function.

[0006] The present application provides an electric iron with a cooling function, which adopts the following technical solution:

[0007] An electric iron with a cooling function, comprising:

[0008] The iron body comprises an iron housing, an ironing board mounted on the bottom of the iron housing, and a water tank mounted inside the iron housing and above the ironing board.

The push rod extends toward the support portion and protrudes from the support portion to be exposed to the outside.

[0015] When the support portion contacts the table top, the push plate is squeezed and moves toward the air guide tube, pushing the heat insulation plate to move so that the air guide cavity is connected to the partition cavity.

[0016] Optionally, the electric iron with a cooling function further includes a dial adjustment mechanism for adjusting the amount of water output, a temperature control knob for adjusting the temperature of the ironing board is rotatably mounted on the iron housing, and a linkage component is provided inside the iron housing to enable the dial adjustment mechanism and the temperature control knob to be adjusted synchronously or to enable the dial adjustment mechanism and the temperature control knob to be adjusted separately.

[0017] Optionally, a water leakage port is provided on the water tank, a guide block is provided on a side of the water tank close to the ironing board, and a water outlet channel is provided on the guide block for communicating with the water leakage port to allow water to flow out and be converted into steam;

[0018] The dial adjustment mechanism includes a blocking rod inserted into the water outlet channel, a dial that drives the blocking rod to slide to control the water output, and a driving spring that drives the blocking rod to reset. The dial is rotatably connected to the iron housing.

[0019] Optionally, a connecting rod is provided on the outer wall of the blocking rod, and a driving groove is provided on the toggle dial for the connecting rod to be inserted to drive the blocking rod to slide, and the driving groove gradually extends toward the axis of the toggle dial along the rotation direction of the toggle dial.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] After ironing is finished, the user can place the iron upright through the support part. At this time, the push rod pushes the heat insulation plate to move, so that the air collecting hood, the air guide cavity and the partition cavity are connected. The heat of the air collecting hood will be transferred to the heating surface of the semiconductor cooling plate through the air guide tube, so that the semiconductor cooling plate has a temperature difference and generates current, which in turn drives the heat dissipation fan to rotate and blow air to the ironing board. The heat dissipation fan and the semiconductor cooling plate are both located inside the iron shell, so that the iron accelerates the cooling of the ironing board without adding additional accessories to increase the space occupancy. In addition, when the iron is ironing normally, the push rod drives the heat insulation plate to move under the action of the return spring, and then separates the inside of the air guide tube into the unconnected air guide cavity and partition cavity, making it difficult for heat to be transferred to the semiconductor cooling plate, and thus the heat dissipation fan is difficult to rotate, which affects the ironing temperature of the ironing board.

[0028] After ironing, water will remain in the water tank. When the switch button is pressed, the lithium battery will power the semiconductor refrigeration chip and micro water pump. The semiconductor refrigeration chip will cool the water in the water tank. Under the action of the micro water pump, the cold water enters the water cooling pipe to cool the ironing board. After that, the water in the water cooling pipe flows back into the water tank under the action of the micro water pump to form a circulating cold water loop, further improving the cooling effect of the ironing board. In addition, the lithium battery will also power the cooling fan. The ambient temperature of the water tank is low due to the cooling effect of the semiconductor refrigeration chip. At this time, the cooling fan can blow the low-temperature air to the ironing board, shortening the cooling time of the ironing board.

[0029] When dry ironing is required, just turn the temperature control knob to adjust the temperature of the ironing board. At this time, the driving column will be located in the yield ring groove and will not interfere with the rotation of the temperature control knob. When steam ironing is required, manually turn the dial to rotate it, which will drive the blocking rod to slide and let the water in the water tank flow out. The blocking rod will drive the driving wheel to rotate, and then the driving column will be inserted into the spiral rotating groove, so that the temperature of the ironing board can be adjusted synchronously according to the water output. If you need to steam iron when turning the temperature control button for dry ironing, you don’t need to turn the temperature control knob to reset it. You only need to turn the dial. At this time, the driving column will rotate and be located in the corresponding yield vertical groove, making the iron suitable for multiple scenarios.

[0030] After the ironing board is cooled by the refrigeration mechanism, the refrigeration mechanism will continue to cool the ironing board, so that the ironing board at low temperature can cool and press the clothes after ironing, ensuring the shaping effect of the clothes.

Implementation Method

[0043] The following is combined with Figure 1-11 This application is described in further detail.

[0044] The embodiment of the present application discloses an electric iron with a cooling function.

[0045] Reference Figure 1 and Figure 2 An electric iron with a cooling function includes an iron body 1, a temperature control mechanism 2 mounted on the iron body 1, a cooling mechanism 3, a dial adjustment mechanism 4, and a linkage assembly 5. The temperature control mechanism 2 is used to adjust the temperature when ironing different garments. The cooling mechanism 3 is mounted inside the iron body 1 and is used to accelerate the cooling of the iron body 1 after ironing. The dial adjustment mechanism 4 is used to adjust the water output of the iron body 1 and, therefore, the steam output. The linkage assembly 5 is used to synchronize the adjustment of the dial adjustment mechanism 4 with the temperature control mechanism 2 or to adjust the dial adjustment mechanism 4 and the temperature control mechanism 2 independently.

[0046] The iron body 1 comprises an iron housing 11, an ironing board 12, and a water tank 13. The ironing board 12 is mounted on the bottom of the iron housing 11 and is used for ironing clothes. The water tank 13 is mounted inside the iron housing and is used for steam ironing. The water tank 13 is located above and spaced apart from the ironing board 12 and contains water for generating steam.

[0047] Reference Figure 2 and Figure 3 The top of the iron housing 11 is provided with a hand-held portion 111 for easy gripping. The front end of the iron housing 11 is pointed, and the rear end of the iron housing 11 is provided with a support portion 112 for standing the iron upright. After ironing, the support portion 112 is placed on a tabletop to prevent the ironing board 12 from contacting the tabletop and causing burns to items on the tabletop. The support portion 112 is equipped with a lithium battery 14 that provides power to the cooling mechanism 3. A switch button 113 is also provided on the side wall of the support portion 112 to control the discharge of the lithium battery 14. When the iron is placed on the tabletop via the support portion 112, the switch button 113 is pressed, and the cooling mechanism 3 will operate to cool the ironing board 12; after cooling is completed, the switch button 113 can be turned off. It is worth noting that the power supply from the lithium battery 14 and the power supply for the iron's own heating are two independent power supply systems. The cooling mechanism 3 can only operate when the lithium battery 14 is discharged.

[0048] Reference Figure 2 The water tank 13 includes a water tank bottom plate 131 and a water tank top shell 132. A water storage cavity is opened on the side of the water tank top shell 132 close to the water tank bottom plate 131. The water tank bottom plate 131 is covered at the cavity opening of the water storage cavity for shielding. The water tank bottom plate 131 and the water tank top shell 132 are fixed together by ultrasonic welding technology.

[0049] Reference Figure 4 On the side of the ironing board 12 near the water tank bottom plate 131, a gas collecting hood 15 is installed that snaps onto the ironing board 12 and collects steam. Water droplets from the water tank 13 fall onto the ironing board 12, generating steam due to the high temperature, which then settles within the gas collecting hood 15. The bottom of the ironing board 12 has steam vents through which the steam in the gas collecting hood 15 is discharged. The gas collecting hood 15 is made of high-temperature resistant material.

[0050] Reference Figure 2 and Figure 4 The temperature control mechanism 2 includes a heating tube 21 and an adjustable thermostat 22. The heating tube 21 is installed on the side of the ironing board 12 near the water tank 13 to heat the ironing board 12. The adjustable thermostat 22 is installed inside the iron housing 11 to control the temperature of the ironing board 12 heated by the heating tube 21.

[0051] Reference Figure 4 and Figure 5The cooling mechanism 3 includes a semiconductor cooling plate 31, a cooling fan 32, an air duct 33, a baffle assembly 34, and a water cooling assembly 35. The semiconductor cooling plate 31 is mounted on the side of the water tank base 131 near the ironing board 12, with its cooling surface in contact with the base 131, to cool the water in the water tank 13. The air duct 33 directs hot air from the air hood 15 to the heating surface of the semiconductor cooling plate 31, creating a temperature difference within the semiconductor cooling plate 31 and generating electricity. When the cooling fan 32 is electrically connected to the semiconductor cooling plate 31 and energized, it blows air into the air hood 15, accelerating the cooling of the ironing board 12. The baffle assembly 34 is slidably mounted on the iron housing 11 to direct hot air from the air hood 15 toward the semiconductor cooling plate 31 or to block the air duct 33 from reaching the semiconductor cooling plate 31, thereby ensuring that the operating temperature of the iron is not affected by the cooling fan 32. The water cooling assembly 35 is used to cool the ironing board 12 with water, thereby further improving the cooling efficiency of the ironing board 12 .

[0052] Multiple semiconductor cooling fins 31 are provided, and these fins are spaced apart and arranged at intervals on the bottom of the water tank bottom plate 131, thereby improving the efficiency of cooling the water in the water tank 13. The top of the air hood 15 is provided with a heat dissipation hole 151 that communicates with the interior of the air hood 15. A cooling fan 32 is installed at the location of the heat dissipation hole 151, thereby facilitating the blowing of air into the interior of the air hood 15. The top of the air hood 15 is also provided with an air guide hole 152 that communicates with the interior of the air hood 15. The air guide pipe 33 is fixedly installed at the top of the air hood 15 and communicates with the air guide hole 152. A micro-worm fan 16 is provided at the location of the air guide hole 152. The micro-worm fan 16 is installed on the side of the air hood 15 near the ironing board 12, thereby transferring the hot air inside the air hood 15 to the air guide pipe 33.

[0053] Reference Figure 4 and Figure 5 The air duct 33 is located below one of the semiconductor cooling sheets 31. A heat conducting plate 36 is attached to the side of the semiconductor cooling sheet 31 corresponding to the air duct 33, which is close to the air duct 33. The heat conducting plate 36 abuts the air duct 33. Hot air in the air hood 15 is transferred to the heat conducting plate 36 through the air duct 33. The heat is then evenly distributed to the corresponding semiconductor cooling sheet 31 through the heat conducting plate 36, preventing the heat from being lost to the air.

[0054] Reference Figure 5 and Figure 6 The air guide tube 33 has an air guide cavity 331 connected to the interior of the air collecting cover 15 and a partition cavity 332 connected to the air guide cavity 331 and facing the semiconductor cooling plate 31.

[0055] The baffle assembly 34 includes a heat shield 341, a push rod 342, a return spring 343, and a spring compression plate 344. The heat shield 341 slides into the air duct 33 to connect or isolate the air duct cavity 331 from the isolation cavity 332. The push rod 342 is connected to the heat shield 341 to drive the heat shield 341 to slide. The push rod 342 protrudes from the iron housing 11, exposed to the outside, and facilitates its movement. The spring compression plate 344 is fixedly mounted on the top of the air hood 15. One end of the return spring 343 is connected to the push rod 342, and the other end abuts the spring compression plate 344, thereby causing the push rod 342 to automatically return to its original position after sliding.

[0056] Reference Figure 3 and Figure 6 The air duct 33 has a sliding groove extending through it on one side near the support portion 112, and the heat insulating plate 341 is inserted into the sliding groove and slides within the sliding groove. The heat insulating plate 341 is made of a heat insulating material. Therefore, when the heat insulating plate 341 separates the air duct cavity 331 and the partition cavity 332, the heat in the air duct cavity 331 is not easily transferred to the partition cavity 332. Among them, the heat insulating plate 341 has an air flow hole 3411. When the push rod 342 slides in the direction close to the air duct 33, it drives the heat insulating plate 341 to slide so that the air flow hole 3411 enters the interior of the air duct 33, thereby connecting the air duct cavity 331 with the partition cavity 332.

[0057] Reference Figure 4 and Figure 6 The end of the push rod 342 closest to the heat shield 341 is fixedly connected to the heat shield 341, while the end of the push rod 342 facing away from the heat shield 341 extends toward the support portion 112, passes through the support portion 112, and is exposed to the outside. This arrangement allows the push rod 342 to be squeezed when the iron is placed vertically on a tabletop, pushing the heat shield 341 to move, thereby connecting the air guide cavity 331 with the partition cavity 332, and facilitating the rotation of the cooling fan 32.

[0058] An ear 3421 is integrally formed on the outer wall of the push rod 342. A spring compression plate 344 is located on the side of the ear 3421 closest to the air guide tube 33, with the spring compression plate 344 and the ear 3421 spaced apart. A return spring 343 is located between the ear 3421 and the spring compression plate 344, with one end of the return spring 343 fixed to the ear 3421 and the other end fixed to the spring compression plate 344. Consequently, when no external force is applied to the push rod 342, the return spring 343 automatically returns the push rod 342 to its original position, allowing the heat shield 341 to isolate the air guide cavity 331 from the isolation cavity 332.

[0059] Reference Figure 4 and Figure 5The water cooling assembly 35 includes a water cooling tube 351 and a micro water pump 352. The water cooling tube 351 is bent into multiple S-shapes and fixed to the top of the ironing board 12, thereby increasing the water cooling area of ​​the ironing board 12. The micro water pump 352 is mounted on the water tank bottom plate 131 and is located near the tail end of the iron. This facilitates the micro water pump 352 to pump water from the water tank 13 when the iron is placed vertically. The water inlet of the water cooling tube 351 is connected to the water outlet of the micro water pump 352, which in turn is connected to the water tank 13. The water inlet of the water cooling tube 351 is connected to the water tank 13, and the water inlet of the micro water pump 352 is connected to the water tank 13, forming a circulating water loop.

[0060] Reference Figure 5 and Figure 7 The water tank bottom plate 131 has a drain port 1311. A guide block 133 is mounted on the side of the water tank bottom plate 131 near the ironing board 12. The side of the guide block 133 near the air hood 15 passes through the air hood 15 and is located within the air hood 15. A water outlet channel 1331 is defined on the side of the guide block 133 near the drain port 1311, communicating with the drain port 1311 and allowing water in the water tank 13 to flow into the air hood 15. A dial adjustment mechanism 4 is mounted on the housing to adjust the amount of water flowing out of the water outlet channel 1331.

[0061] Reference Figure 7 and Figure 8 The dial adjustment mechanism 4 includes a blocking rod 41 inserted into the water outlet channel 1331, a dial 42 that drives the blocking rod 41 to slide to control the water output, and a drive spring 43 that resets the blocking rod 41. The blocking rod 41 inserted into the water outlet channel 1331 prevents water from the water tank 13 from leaking through the water outlet channel 1331. The dial 42 is rotatably mounted on the iron housing 11. The dial 42 is connected to the blocking rod 41, driving the blocking rod 41 to slide, thereby opening the water outlet channel 1331. The drive spring 43 is mounted on the blocking rod 41, allowing the blocking rod 41 to slide back into place as the dial 42 rotates.

[0062] One end of the blocking rod 41 that is inserted into the water outlet channel 1331 is integrally formed with a tapered post 44. The diameter of the tapered post 44 gradually decreases as the blocking rod 41 is inserted into the water outlet channel 1331. When the blocking rod 41 moves upward under the action of the dial 42, the diameter of the water outlet channel 1331 is gradually increased, thereby increasing the amount of water discharged.

[0063] Reference Figure 3 and Figure 8A support base 45 is mounted within the iron housing 11, and a dial 42 is rotatably mounted on the support base 45 via a rotating shaft. A connecting rod 411 is integrally formed on the outer wall of the blocking rod 41. The dial 42 defines a drive slot 421 for the connecting rod 411 to slide the blocking rod 41. The drive slot 421 extends gradually toward the axis of the dial 42 as the dial 42 rotates. Consequently, as the dial 42 rotates, the blocking rod 41 moves toward the axis of the dial 42.

[0064] Reference Figure 8 The blocking rod 41 is sleeved with an abutting ring 412, which is located below the support seat 45 and is fixedly connected to the blocking rod 41. One end of the driving spring 43 abuts against the abutting ring 412, and the other end abuts against the support seat 45.

[0065] Reference Figure 4 and Figure 9 The temperature control mechanism 2 also includes a temperature control knob 23 rotatably mounted on the iron housing 11 for adjusting the adjustable thermostat 22. The temperature control knob 23 includes a temperature control shaft 231 and a rotary knob 232. The temperature control shaft 231 rotates synchronously with the rotary knob 232 and is connected to the adjustable thermostat 22. The rotary knob 232 protrudes from the iron housing 11 for easy rotation by the user. The temperature control shaft 231 is located inside the iron housing 11.

[0066] Reference Figure 9 、 Figure 10 as well as Figure 11 The linkage assembly 5 includes a rack 51, an active synchronous pulley 52, a driven synchronous pulley 53, a driving wheel 54, a synchronous belt 55 and a driving column 56. The rack 51 is integrally formed on the upper outer wall of the blocking rod 41. The active synchronous pulley 52 is rotatably mounted inside the water tank 13 and meshes with the rack 51. The driven synchronous pulley 53 is rotatably mounted inside the water tank 13, and the driven synchronous pulley 53 rotates synchronously with the active synchronous pulley 52 through the synchronous belt 55. The driving wheel 54 rotates synchronously with the driven synchronous pulley 53. The driving column 56 is integrally formed on the outer wall of the driving wheel 54 and is used to drive the temperature control shaft 231 to rotate.

[0067] A first extension plate 57 and a second extension plate 58 are integrally formed on the top of the water tank bottom plate 131. The first extension plate 57 is located on one side of the blocking rod 41, and the second extension plate 58 is located on one side of the temperature control shaft 231. The driving synchronous pulley 52 is rotatably mounted on the first extension plate 57 via a rotating shaft; the driven synchronous pulley 53 is rotatably mounted on the second extension plate 58 via a rotating shaft. The driving pulley 54 and the driven synchronous pulley 53 are integrally formed and share the same rotating shaft.

[0068] Reference Figure 10 and Figure 11The outer wall of the thermostat shaft 231 is provided with a spiral groove 2311 for the drive post 56 to be inserted into. The spiral groove 2311 extends spirally along the axial direction of the thermostat shaft 231. Rotation of the drive wheel 54 causes the drive post 56 to move in the spiral groove, thereby driving the thermostat shaft 231 to rotate and adjust the temperature.

[0069] The outer wall of the temperature control knob 23 also defines a clearance groove 2312 for the drive post 56 to insert into and communicate with the spiral rotation groove 2311. The clearance groove 2312 is located on the side of the spiral rotation groove closest to the rotation knob 232. When the rotation knob 232 is rotated to adjust the temperature, the drive post 56 moves within the clearance groove 2312 without interfering with the rotation of the temperature control shaft 231.

[0070] Reference Figure 10 and Figure 11 A plurality of vertical clearance grooves 2313 are defined on the outer peripheral wall of the temperature control shaft 231. The plurality of vertical clearance grooves 2313 are all connected to the annular clearance groove 2312 and are located on the side of the annular clearance groove 2312 away from the rotary knob 232. The plurality of vertical clearance grooves 2313 are arranged circumferentially at intervals on the temperature control knob 23. When the temperature control knob 23 is rotated to adjust the dial adjustment mechanism 4, the driving column 56 is rotated to be located in one of the vertical clearance grooves 2313.

[0071] The operating principle of an electric iron with a cooling function according to an embodiment of the present application is as follows: After ironing, the user can first place the iron upright on a table via the support portion 112. At this time, the push rod 342 is squeezed and pushes the heat insulation plate 341 to move, thereby connecting the air collection cover 15, the air guide cavity 331, and the partition cavity 332. Heat from the air collection cover 15 is transferred through the air guide duct 33 to the heating surface of the semiconductor cooling plate 31 by the micro-worm fan 16, causing the semiconductor cooling plate 31 to generate a temperature difference and generate current, which in turn drives the cooling fan 32 to rotate and blow air to the ironing plate 12. The cooling fan 32 and the semiconductor cooling plate 31 are both located inside the iron housing 11, allowing the iron to accelerate the cooling of the ironing plate 12 without adding additional accessories to increase space usage.

[0072] Secondly, when the iron is placed upright on a table, the power button 113 can be pressed. The lithium battery 14 will power the semiconductor cooling chip 31 and the micro water pump 352. The semiconductor cooling chip 31 will cool the water in the water tank 13. The cold water, driven by the micro water pump 352, will enter the water cooling pipe 351 to cool the ironing board 12. The water in the water cooling pipe 351 will then flow back into the water tank 13 under the action of the micro water pump 352, forming a circulating cold water loop, further improving the cooling effect on the ironing board 12. The lithium battery 14 will also power the cooling fan 32. The cooling effect of the semiconductor cooling chip 31 will lower the ambient temperature of the water tank 13. At this time, the cooling fan 32 can blow low-temperature air toward the ironing board 12, shortening the cooling time of the ironing board 12.

[0073] Finally, when clothes require dry ironing, the temperature of the ironing plate 12 can be adjusted by turning the temperature control knob 23. The drive post 56 will then be located in the clearance groove 2312, preventing interference with the rotation of the temperature control knob 23. When steam ironing is desired, the dial 42 can be manually rotated, causing the blocking rod 41 to slide, allowing water in the water tank 13 to flow out. The sliding of the blocking rod 41 will drive the driving synchronous pulley 52 to rotate. The driving synchronous pulley 52, driven by the timing belt 55, will then rotate the driven synchronous pulley 53. The drive pulley 54 will then rotate synchronously with the driven synchronous pulley 53, causing the drive post 56 to be inserted into the spiral rotation groove 2311, allowing the temperature of the ironing plate 12 to be adjusted synchronously with the water output. When steam ironing is desired while the temperature control knob is being used for dry ironing, the temperature control knob 23 does not need to be reset; the dial 42 can be simply rotated. The drive post 56 will then be located in the corresponding clearance groove 2313, making the iron suitable for multiple scenarios.

[0074] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
