在一些实施例中，如图7所示，蒸汽洗预处理洗涤流程，主要包括以下步骤：
进水步骤S21：开启电磁阀17，开启水泵12，供水源中的水通过水泵12泵入进液管道11。
判断水流开关电位变化步骤S22：判断加热装置前端管道上设置的水流开关，当水流开关的电位发生变化时，进入加热步骤S23。
加热步骤S23：控制器开启加热装置，加热装置能够在短时间内将流经加热装置的水进行加热，经加热后，水的温度能够达到95°以上，水流经加热装置的时间在10-30s。
喷洗处理步骤S24：控制器开启雾化喷嘴16，高温水经出液管道15至雾化喷嘴16，雾化喷嘴16将高温水转化为雾汽状态，高温雾汽在水泵12压力的作用下，高速喷射到洗涤室21，并对碗碟上的残渣进行软化处理。
判断喷洗时间是否结束步骤S25：控制器预设高温雾汽喷洗的时间阈值，高温雾汽在预设时间内对洗涤室21内的碗碟进行高温喷洗。在一些实施例中，高温雾汽喷洗处理的时间控制在20-30分钟。当高温雾汽的喷洗时间达到阈值时，则进入关断步骤S26；
关断步骤S26：关闭雾化喷嘴16、关闭加热装置、关闭水泵12、关闭电磁阀17；
调用预设洗涤流程步骤S27：调用预设洗涤流程对碗碟进行洗涤。
该蒸汽发生器1采用即热式发热管加热水，对流经水即热加热，通过雾化喷嘴16喷出雾气对内胆2进行高温喷洗，对内胆2内放置的碗碟进行高温蒸汽预处理，该加热方式简 单，节能效果好，有效避免锅炉中的水长时间加热而造成细菌滋生或产生异味的情况。洗碗机通过设置多个雾化喷头，能够全方位的对洗碗机内的餐具进行预处理，高温雾化的作用能够将碗碟上的残留物进行高温蒸汽软化，对于碗碟的残留物清洗的更彻底、无残留物的问题出现，同时也能够缩短整个洗涤模式的时间，更加节能。该洗碗机在预设洗涤流程之前加入蒸汽洗预处理洗涤流程，能够通过蒸汽软化碗碟上的残留物，使后面的冲水洗涤过程更加顺利，大大提升洗碗机的洁净度以及清洁效率。
