Description

Technical Field

[0001] This utility model relates to the field of steam generating equipment technology, and in particular to an instantaneous high-efficiency steam generating device. Background Technology

[0002] An instantaneous high-efficiency steam generator is a device that directly heats a flowing liquid using an electric heating element, bringing it to the desired temperature or causing it to vaporize and produce steam within a short time. Its basic principle is to utilize the resistance heating effect of conductive materials to convert electrical energy into heat energy, thereby rapidly heating the liquid. Specifically, when water flows through the heating element, the current passing through the element generates heat, which is quickly transferred to the liquid, raising its temperature and achieving an instantaneous heating effect. Its core features are instant heating, on-demand supply, and energy efficiency, making it widely used in homes, industry, and commerce.

[0003] In order to fully utilize the heat generated by the heating element, traditional liquid heating equipment typically uses multiple spiral tubes for heating to quickly provide hot water. For example, an energy-saving heater with patent application number 202120709759.2 includes a shell, a first spiral tube, a second spiral tube, and multiple heating components. The heating components are parallel to the first spiral tube and evenly distributed around its circumference. The second spiral tube has a surrounding cavity, within which the first spiral tube and multiple heating components are partially housed. Both ends of the second spiral tube are connected to the first spiral tube. The first spiral tube, the second spiral tube, and the multiple heating components are all fixedly housed within the shell, with both ends of the heating components protruding outside the shell. The shell, the first spiral tube, the second spiral tube, and the multiple heating components are all integrally formed. The above scheme combines spiral tubes and straight tubes to form multiple water inlets and outlets. However, if the above scheme is directly applied to a steam generator, it is very easy to cause uneven heating. The flow distance of the straight tube is short while that of the spiral tube is long. When the spiral tube generates steam with high heating power, the straight tube still discharges hot water and cannot stably produce steam. Utility Model Content
