In the technique scheme, the steam condensation channel can or be connected with the pipeline configuration of condensing fin for coil arrangement.Also can be the condensation structure of other form, as long as steam is condensed into water.
In the technique scheme, the link of the pump housing and steam condensation channel and the oneself height of steam condensation channel all are higher than the maximum fluid height that storage tank sets.
In the technique scheme, the steam condensation channel be the horizontal cross setting or towards storage tank by height to the low dip setting.
In the technique scheme, control circuit comprises the sensor that is used for monitoring the inner bag steam pressure.
In the technique scheme, heating casing rear side surface can be provided with plural horizontal row to the passage that is provided with.
The operation principle of the utility model is: when sensor senses when heating casing internal gas pressure is pressed greater than the casing atmosphere outside; Control circuit output control signal and driving pump body running; The pump housing is extracted the steam that exceeds the external pressure part in the casing out and is delivered to the steam condensation channel in casing; Steam becomes aqueous water and flows in the storage tank and can be utilized once more through condensation; Or control circuit do not establish sensor, obtain the signal (for example: chamber door is closed, the enabling signal of enabling signal or time-delay etc.) of complete permission pump housing work at control circuit after, the direct-driven pump body running.
Compared with prior art, the utlity model has following beneficial effect:
1. through the operation of Pneumatic controller, the steam pressure that can keep heating in the box liner is consistent with the outer air pressure of casing, realizes that food odors does not leak;
2. can effectively keep the stable of ambient humidity, avoid humid air the infringement of kitchen tools on every side;
3. after the steam that exceeds the casing external pressure being carried out condensation,, reduce the required moisturizing number of operations of alimentary system work with the condensed water cycling and reutilization; 4. the passage design of heating casing rear side surface can realize the heat exchange between steam condensation channel and the outside atmosphere that heats casing.
