Description
Technical field
The present invention relates to a kind of steam generator, particularly a kind of heat accumulating type steam generator for food baking oven.
Background technology
Existing steam generator on food oven mainly contains and steams pot formula and directly enter ability of swimming two kinds.
Steam pot formula: utilize electrothermal tube to be heated to uniform temperature to steam pot, heat storage in steam pot, when user needs steam, water is injected in steam pot, water becomes steam under the heat effect of former storage, and it is inner that steam imports baking oven through mozzle, reaches steam object.
Steam pot formula and there is following shortcoming:
1, energy resource consumption is large, within 1 hour, consumes nearly 3 degree of electricity.Because it is arranged at outside baking oven, general temperature reaches 200 DEG C or 300 DEG C of high temperature, and shell heat insulation effect is bad, causes the moment to be heated.
2, take up room, transport, use inconvenience.
3, fault rate is high.Because heating source (electrothermal tube) will be increased in addition, want temperature to control simultaneously, once temperature controls malfunctioning, its heating can cause pot body to damage, because its electric heating controls relative complex, electrothermal tube shortened greatly in frequent lower its service life that colds and heat succeed each other, and used electric original paper relatively many simultaneously, too increased its fault rate;
4, quantity of steam is few.Within every 1 second, 10 grams of water can only be changed into steam, and can only continue at every turn 2 second steam, be equivalent to 20 grams of water and change into steam.One, the steam duration is short, because it utilizes electrothermal tube to heat heat storage in pot body, almost consumes a few second when its heat stored converts steam to water, when heat exhaustion is to less than 100 DEG C, its evaporation of water is just relatively less or do not evaporated; It two is that its store heat is few, and because it is that to be positioned over baking oven outer or hang on baking oven, its volume can not do too large, and the heat of the little relative storage of its volume is also few, and the water of evaporation is also relatively less.
Directly enter ability of swimming: utilize the heat that baking oven inner chamber wind path wall is saved in the course of work, water directly injects air channel and steam occurs.
Directly enter ability of swimming and there is following shortcoming:
1, quantity of steam is few.Because it utilizes the heat of inner chamber wind path wall and distinguished and admirable drive and makes the water in injection air channel evaporate produce steam, the temperature major part of inner chamber wind path wall is with temperature in burner hearth, therefore its temperature can not be too high, the metal plate material adding upper air duct only has 1mm, any process is not done to water trend again, the heat of its savings also can not be too many, purely utilize the effect of temperature and water and produce steam.
2, there is pollution to the product toasted in stove.When water injects behind air channel, a part of water evaporates in air channel, and some tiny globule (unboiled water) directly enters burner hearth and acts on food along air channel, and some harmful substances in water can direct contaminated food products, or affects food mouthfeel.
Therefore, be necessary to make further improvements.
