A kind of condensate return structure of electric steam furnace
Technical field
The present invention relates to a kind of electric steam furnace, in particular to the condensate return structure of a kind of electric steam furnace.
Background technique
Electric steam furnace is a large amount of high-temperature steams to be generated by the way of electric-heating water, and add to food by high-temperature steam
The cooking appliance of heat;Electric steam furnace can be such that the pressure in furnace chamber is continuously increased while heating generates high-temperature steam, to avoid furnace
Cavity pressure is excessively high, needs for a part of steam in furnace chamber to be discharged to outside furnace chamber.Traditional scheme are as follows: directly arrange high-temperature steam
Out to outside furnace chamber, the program can there are the following problems: 1, can generate when human body accidentally touches the high-temperature steam of discharge
The problem of scalding skin;2, steam is constantly discharged, and the water consumption that will lead in water tank is too fast, when being unable to maintain that longer culinary art
Between;3, waste water resource.
Chinese patent literature CN207152423U disclosed on March 20th, 2018 a kind of recycling of condensed steam mechanism and
Using the cooking equipment that steams for having the mechanism, and specifically disclose the row including air exhauster, being connected to air exhauster air outlet
Wind channel and steam condensation chamber, steam condensation chamber are equipped with steam inlet hole and venthole, and wherein venthole and air exhaust passage connect
It is logical;It further include upper mounting plate, wind deflector, steam heat-exchanging plate, upper mounting plate is located at below wind deflector and is formed between wind deflector
