Description

Technical Field

[0001] The utility model belongs to the field of steam ovens, and in particular relates to a negative pressure dehumidification mechanism of a steam oven and the steam oven. Background Art

[0002] Steam ovens were invented to meet people's ever-expanding cooking needs. Initially, steaming or baking alone were no longer sufficient, so people began experimenting with combining the two, resulting in the steam oven. The development of steam ovens has gone through several stages, from the initial simple steamer or oven to today's intelligent, multifunctional steam ovens, with continuous technological innovation and upgrades. The main principle of a steam oven is to use electric heating elements to convert electrical energy into heat energy, which is then transferred to the surface of the food, achieving the desired effect of baking, roasting, or steaming. Steam ovens are also equipped with a temperature controller and timer, allowing the heating element temperature and time to be adjusted as needed to achieve the desired cooking effect.

[0003] Steam ovens generate large amounts of steam when in operation. This steam accumulates within the oven cavity, forming moisture. Without an effective dehumidification function, this moisture can affect the cooking process, resulting in poor taste, burnt exterior, and raw interior. To improve the humidity within the steam oven and enhance cooking results, dehumidification technology is crucial. Dehumidification effectively lowers the humidity inside the oven, minimizing the accumulation of fumes and steam, ensuring optimal cooking results.

[0004] Some traditional ovens achieve dehumidification by increasing the baking temperature to evaporate moisture inside the oven. However, this method has limitations: it only dehumidifies when the oven is heated, and the dehumidification effect is not significant. Chinese Patent Publication No. CN109855402A discloses an oven container condensation dehumidification device that primarily dehumidifies the oven interior through a condenser.
