This utility model provides a door assembly and a steam oven including the same. The door assembly is used in the steam oven and includes a door and a water tank. The door is used to open or close the steam oven, and the water tank is installed on the door and located inside the steam oven. The door is made of a high-temperature resistant transparent material so that the user can observe the water level in the water tank from the outside of the steam oven. The transparent material of the door makes the water tank visible, reminding the user to add water before cooking, effectively avoiding interruptions in cooking due to lack of water. The integrated design of the door and water tank utilizes the heat that would otherwise be lost at the door, serving as preheating water and improving energy efficiency. At the same time, the high specific heat capacity of water can act as insulation, reducing the temperature of the outer surface of the door. In addition, the installation method of the water tank does not occupy the cooking cavity space of the steam oven, increasing the effective volume of the cooking cavity and making the whole machine more compact.
