Although the condensing device (such as a condensing cavity, a condensing box, etc.) is arranged to condense the steam, thereby reducing the amount of the discharged steam to a certain extent, the existing condensing device generally directly uses the outlet air of the exhaust passage of the steam box as a cold source to condense the steam entering the condensing device, and the condensing effect on the steam still needs to be improved.
Further, the steam generating device of the existing steaming cooking equipment has two specific setting modes: firstly, an external steam generating device is arranged outside an inner container, and steam generated after water in a water tank is input into the external steam generating device through a water path is input into the inner container through a steam inlet pipe; second, a built-in steam generator is disposed in the inner container (generally, a heating plate disposed in the inner container), water in the water tank is directly input into the inner container through a water path, and steam is generated by directly heating the water in the inner container. Still further, some steaming cooking devices (such as a steam box with a built-in steam generating device) directly return to the inner container and are reheated to generate steam, and some steaming cooking devices return the condensed water to the water tank.
