AI Technical Summary
Existing steam ovens typically require additional blower devices to quickly remove excess steam from the inner cavity during the steaming process, which increases costs.
The hot air blower inside the steam oven stirs up the high-temperature steam in the cooking cavity, and the negative pressure accelerates the discharge of the steam. Combined with the design of the negative pressure zone and air inlet, the steam can be discharged quickly without the need for an additional blower.
It enables the rapid removal of excess water vapor from the inner liner, ensuring that food is heated evenly, avoiding additional costs, and improving the reliability and service life of the hot air blower.
