Example Embodiment

[0019] The technical solutions of the present invention will be described below in conjunction with the accompanying drawings and embodiments.
[0020] like figure 1 As shown, a boiler assembly according to the present invention includes a boiler body 1 and a heating plate 3. It is characterized in that the lower end surface of the boiler body 1 is a convex arc surface 2, and the upper end surface of the heating plate 3 is The inner concave arc surface 4, the lower end surface of the boiler body 1 and the upper end surface of the heating plate 3 are fixedly connected through the aforementioned mutually matching arc surfaces. In the boiler assembly of the present invention, the boiler body 1 and the heating plate 3 are connected by matching arc surfaces. Due to the special shape of the arc surfaces, the pressure required at the bottom of the boiler is smaller under the same pressure, so that even if the boiler The internal steam pressure is increased to a higher level, and the pressure on the boiler will not cause the boiler to bulge and deform. At the same time, the arc-shaped bottom of the boiler itself has a bulging shape, which can further prevent the boiler from bulging and deforming. Boiler and heat The plates 3 can be kept in a reliable connection state, so that the heat transfer structure between the heating plate 3 and the boiler will not fail, and the boiler can continuously produce steam when it is working. The arc-shaped surface adopted between the boiler body 1 and the heating plate 3 can be a special arc-shaped matching form of a spherical surface, which can better avoid swelling and deformation when the internal pressure of the boiler is high.
[0021] like figure 1 As shown, the boiler body 1 includes an upper shell 5 and a lower shell 6, and the upper shell 5 and the lower shell 6 are connected by welding; the boiler body 1 and the heating plate 3 are brazed fixed connection. The assembly scheme of the upper shell 5 and the lower shell 6 makes the boiler easier to assemble, and the connection by welding can improve the connection stability and reliability of the assembled structure.
[0022] like figure 1 As shown, the heating plate 3 includes a chassis 7 and a heating pipe 8 , and the heating pipe 8 is embedded in the chassis 7 by die-casting. The heat generated by the heating tube 8 is quickly and evenly transferred to the boiler through the heating plate 3, which is beneficial to improving the heating efficiency.
[0023] like figure 1 As shown, the steam outlet end of the boiler body 1 is connected with a solenoid valve 9, and the drain end of the boiler body 1 is provided with a drain plug 10, and a sealing ring is sleeved on the drain plug 10. The solenoid valve 9 can close or open the boiler, can control the internal pressure of the boiler, and can also avoid accidental steam ejection; the drain plug 10 can open or open the drain end of the boiler, which not only facilitates the discharge of sewage, but also improves the sealing of the drain end when matched with the sealing ring sex.
[0024] like figure 1 As shown, the boiler body 1 is provided with a water level sensor 11 , and the heating plate 3 is connected with a ground wire terminal 12 and a temperature controller 13 . The water level sensor 11 can automatically control the water level in the boiler, realize automatic water replenishment, and avoid insufficient water in the boiler; after the ground wire terminal 12 is grounded, the electrical safety of the heating plate 3 can be improved, and the temperature controller 13 can automatically control the heating plate 3. The heating state of the boiler further controls the steam pressure in the boiler.
[0025] The present invention also provides a steam ironing device, such as figure 2 As shown, it includes a water tank 14, a water pump 15 and an iron 16. It is characterized in that it also includes the above-mentioned boiler assembly. The water tank 14 and the water pump 15 are connected to the water inlet end of the boiler assembly in sequence through pipelines. The iron 16 is connected to the steam outlet of the boiler assembly through a pipeline. The steam ironing equipment adopting the boiler assembly in the present invention can iron clothes under higher steam pressure, not only has good ironing effect, but also has faster ironing speed and is very convenient to use.
[0026] like figure 2 As shown, the iron 16 has a bottom plate 17, a steam chamber 18 and a heater 19, the heater 19 is used to heat the steam chamber 18, and a plurality of steam holes are opened on the bottom plate 17, and the steam holes It communicates with the steam chamber 18. The heater 19 can reheat the steam entering the steam chamber 18 to increase the temperature of the steam and further improve the ironing effect.
[0027] like figure 2 As shown, the iron 16 is provided with a control board 20 connected to the heater 19 for controlling the heating state of the heater 19 . After the control board 20 adjusts the heating state of the heater 19, the steam in the steam chamber 18 is more suitable for the ironing requirements of clothes of different materials, so as to ensure the ironing effect.
[0028] like figure 2 As shown, the steam ironing equipment also includes a controller 21, the water level sensor 11 and the temperature controller 13 on the boiler body 1 are respectively connected to the input end of the controller 21, the water pump 15, the heating plate 3 The heating pipe 8 , the control board 20 in the iron 16 and the solenoid valve 9 on the boiler body 1 are respectively connected to the output end of the controller 21 . The controller 21 receives signals from various components connected to its input end, and then automatically controls the working state of each component connected to its output end, so that the boiler assembly can automatically and reliably operate.
[0029] like figure 2 As shown, the iron 16 is provided with a release button 22, and the release button 22 is connected to the input end of the controller 21 through an electrical circuit. A release button 22 is designed on the iron 16 so that the user can more conveniently control the release of steam during use.
[0030] When using the steam ironing equipment of the present invention, the controller 21 will automatically control the water pump 15 to extract water from the water tank 14 to supplement the boiler through the water level signal detected by the water level sensor 11 in the boiler body 1, so that the water volume in the boiler Sustained at a sufficient level. At the same time, the controller 21 will also control the heating state of the heating tube 8 according to the temperature controller 13, so that the heating tube 8 heats the heating plate 3, and then transfers the heat to the boiler body 1 to heat the water in the boiler to generate steam. When starting to heat, the solenoid valve 9 on the boiler body 1 is in a closed state, so that a closed space is formed inside the boiler body 1, and when the steam is increasing, the steam pressure in the boiler will gradually rise. Since the boiler body 1 is fixedly connected with the heating plate 3 by the arc surface, the boiler can withstand higher pressure, and the steam pressure inside the boiler can also be raised to a higher level. At the same time, the heat transfer structure between the boiler body 1 and the heating plate 3 No problem either. When the pressure in the boiler reaches the ironing requirement, the user can hold the iron 16 and press the release button 22 at the same time to send a signal to the controller 21, and the controller 21 can control the solenoid valve 9 to open, and the steam in the boiler will Enter the steam chamber of the iron 16 through the steam outlet along the pipeline; the controller 21 will also send a signal to the control board 20 at the same time, so that the control board 20 controls the heater 19 to heat, and the steam in the steam chamber 18 will be heated twice. Secondary heating to enhance and maintain the high-temperature state of the steam; in addition, because a small amount of condensed water produced by the steam during the pipeline conduction process will also enter the steam chamber 18, the heater 19 will heat the steam chamber 18 when it is heated. The water vaporizes, causing it to also be heated into steam. The high-temperature and high-pressure steam in the steam chamber 18 is ejected from the steam holes on the bottom plate 17, so that the clothes can be ironed.
[0031] The above is only a preferred embodiment of the present invention, so all equivalent changes or modifications made according to the structure, features and principles described in the scope of the patent application of the present invention are included in the scope of the patent application of the present invention.
