Description

Technical Field

[0001] The utility model belongs to the technical field of catering equipment, and particularly relates to a circulating steam oven. Background Art

[0002] An electric oven is an electrical appliance that bakes food through electric heating tubes. It has the advantages of being convenient and fast, but it also causes the loss of moisture inside the food, resulting in the surface of the baked food being dry and hard, or even burnt, affecting the taste of the food. To this end, related products have added microwave, steam and other functions to the electric oven, and steam is introduced into the oven to increase the moisture of the food. However, the above ovens have the following shortcomings: (1) Usually, a water tank and a steam generator are added to the oven, and the generated steam is introduced into the oven cavity for hot steaming; however, the amount of steam is small and the steam cannot be circulated and heated in the oven cavity. (2) After the steam in the oven cools, condensed water is formed and retained inside the oven, which is prone to breed bacteria. (3) The heated steam cannot be discharged from the oven in time, which is prone to cause odor contamination when baking again. Summary of the invention

[0003] In view of the deficiencies in the prior art, the utility model provides a circulating steam oven, which combines multiple functions such as steam heating and baking, and has a circulating steam heating effect.
