Specifically, when the cooking device cooks food, steam generated in the cooking cavity 11 enters the condensation cavity 31352 of the condenser 313 through the first exhaust pipe 311, high-temperature condensed water generated in the cooking cavity 11 enters the condensation cavity 31352 through the first exhaust pipe 321, most of the steam and the high-temperature condensed water are condensed in the condensation cavity 31352 to form low-temperature condensed water, the low-temperature condensed water is discharged to the outside through the second exhaust pipe 323, and a small amount of steam is discharged to the outside through the second exhaust pipe 312, the discharge system 30 can effectively reduce the discharge amount of the steam, avoid the situation that the steam scalds users, and avoid adverse effects on the service lives of other electric appliances in a kitchen and kitchen furniture due to the increase of air humidity.

In addition, the cooking appliance is a steam box or a steam oven, and other structures of the cooking appliance refer to the prior art, which are not described herein again.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
