Description

Technical Field

[0001] This utility model relates to a steam oven. Background Technology

[0002] The existing technology, Chinese patent 201921239953.8, describes a steam-top steam oven, including a cabinet and a door. The cabinet contains an inner liner forming a steam-baking chamber. The door swings open on the opening of the inner liner to open or close the chamber. A drawer-type water tank is located on one side of the top of the cabinet, and a water pump and a steam generator are located on the other side. The water tank supplies water to the steam generator via the pump. The steam generator's outlet is connected to the top of the inner liner to input steam into the steam-baking chamber. Compared to the prior art, this invention places the water tank and steam generator at the top of the cabinet, using the steam generator to produce steam and directly discharge it into the steam-baking chamber from above, resulting in higher steam generation efficiency. The rational distribution of the water tank and steam generator's installation positions also makes the structure more compact and rational.
