Description

Steam generator and steaming cooking equipment Technical Field The utility model relates to kitchen appliance equipment, in particular to a steam generator and steaming cooking equipment. Background In the field of kitchen appliances, a steam generator is an indispensable component in a steam box, a steam oven and other equipment, and the main function of the steam generator is to generate steam through heating so as to provide a needed high-temperature steam environment for cooking. At present, a common steam generator heating device mostly adopts a heating disc type structure. However, in the heating disc type steam generator structure, the heating disc is directly exposed in the liner, heat generated in the heating process can be greatly dissipated to the surrounding space, the area of the heating disc which is directly contacted with water is limited, and the heat transfer efficiency is low. Due to the limited heat dissipation and heated area, the rate of transition of water from a liquid state to a gaseous state is slow, and during cooking, the user needs to wait a long time to generate enough steam to steam the food. This not only reduces the cooking efficiency, but may also cause inconvenience to the user during use, especially in situations where rapid cooking is required, such as breakfast preparation or emergency dining scenarios.
