For example, the condensation vent 212 is formed by the protrusion of the inner surface of the condensation floor support 250 toward the condensation recovery chamber 210, which is simpler in structure, facilitating the manufacturing process of the condensation floor support 250.
Optionally, the heat dissipation air duct 120, the condensation recovery chamber 210 and the condensation bottom plate 220 form an e-shaped exhaust channel, and the vapor discharged from the condensation exhaust port 212 discharges the low-temperature low-moisture vapor to the environment through the heat dissipation air duct outlet 122 under the action of the heat dissipation fan 110.
Example two
The second embodiment provides a steam boiler, the embodiment includes the condensation recovery apparatus described in the first embodiment, and the technical features of the condensation recovery apparatus disclosed in the first embodiment are also applicable to the embodiment, and the technical features of the condensation recovery apparatus disclosed in the first embodiment are not repeated.
Referring to fig. 1 to 7 of the first embodiment, the steam oven provided in this embodiment includes an inner container 300 and a condensation recovery device;

Optionally, the steam exhaust port of the inner container 300 is communicated with the condensation air inlet 211 of the condensation recovery device through a hose such as a silicone tube, a plastic hose or a rubber tube.
In the steam oven of the present embodiment, the steam in the condensation recovery chamber 210 of the condensation recovery device exchanges heat with the gas in the heat dissipation air duct 120 through the condensation bottom plate 220, so that the steam is condensed and cooled on the condensation bottom plate 220 to reduce the moisture content in the steam and the temperature of the steam, and then the steam enters the heat dissipation air duct 120 from the condensation exhaust port 212; in the heat dissipation air duct 120, the steam is mixed with a large amount of air continuously provided by the heat dissipation fan 110, so that the moisture content and the steam temperature in the steam are further reduced; the steam is then exhausted through the radiant tunnel outlet 122. The temperature of the steam discharged from the outlet 122 of the heat dissipation air duct is low, the moisture content is low, the damage to operators is basically avoided, and the damage of the moisture in the steam to the whole environment of the kitchen and the steam oven body is greatly reduced.
In an alternative of the present embodiment, the condensation recovery assembly 200 of the condensation recovery apparatus is provided with a water return port 251 for collecting condensed water;
the water return port 251 is communicated with the heating disc of the inner container 300, so that condensed water is recycled, the water consumption of the steam oven is reduced, and the continuous water consumption time of the steam oven is prolonged.
