The specific embodiment
Embodiment is described in further detail the present invention below in conjunction with accompanying drawing.
See also Fig. 1～water tank structure of electric steamer shown in Figure 7, comprise water tank outer cover 1, water tank outer cover 1 one ends are Open architecture, be provided with storage tank 2 in the water tank outer cover, storage tank 2 is movably arranged in the described water tank outer cover 1 by the open end of described water tank outer cover one side, and described storage tank 2 and described water tank outer cover 1 a corresponding side is provided with handle 21; The bottom of storage tank 2 is electric boiling plate 3.Storage tank 2 inside are provided with evaporation tank 4, described evaporation tank 4 be the inverted T shape structure, and the top of described evaporation tank 4 is fastened in the open top of described storage tank 2 by a cover plate 5, be provided with buckle 51 on the cover plate 5, the position that the inwall of storage tank 2 is corresponding with buckle is provided with draw-in groove, can make things convenient for the fixing or dismounting of evaporation tank 4; Evaporation tank 4 tops are provided with steam outlet 41, and steam outlet on the evaporation tank 4 41 is communicated with steam port 11 on the water tank outer cover 1 by steam mozzle 6, and this steam port 11 is connected with the cooking chamber of electric steaming device; Evaporation tank 4 bottoms are hatch frame, and the shape of evaporation tank 4 bottom openings is consistent with the shape of described storage tank 2 bottom margins, evaporation tank 4 bottom openings are wrapped with a sealing ring 7, sealing circle 7 is heat insulation rubber ring, and be provided with a small gap 71 that can allow liquid communication on the sealing circle 7, described evaporation tank 4 bottoms are sealingly fastened on described storage tank 2 bottoms by described sealing ring 7, and described sealing ring 7 outsides are provided with a circle liquid communication guiding gutter 72, and this liquid communication guiding gutter 72 is connected with described small gap 71.
Be provided with the condensate return mouth 12 that is communicated with storage tank on the water tank outer cover 1, condensate return mouth 12 is communicated with the bottom of electric steaming device cooking chamber, after steam condensation in electric steaming device cooking chamber forms water droplet, flow back to storage tank by the condensate return mouth, make the water can be recycling.
In addition, be provided with the condensate return mouth 12 that is communicated with storage tank on the water tank outer cover 1.Be provided with in the water tank 2 for the buoy 8 of measuring water storage tank water level; be provided with magnet on the buoy 8; be provided with the tongue tube (not shown) on the storage tank inwall corresponding with buoy magnet or the water tank outer cover, the signal output part of this tongue tube links to each other with external warning circuit.
During use, storage tank is extracted out in the water tank outer cover, toward the storage tank topped up with water, liquid communication guiding gutter and the small gap on the sealing ring that water in the storage tank can slowly pass through the evaporation tank bottom flow in the evaporation tank, because evaporation tank is the inverted T shape structure, and the breach less on the sealing ring, water is slowly constantly must flow in the evaporation tank, the water yield in the evaporation tank is less comparatively speaking, electric hot plate is when the energising heating, need not heat the water in the whole storage tank, and only need the water in the heating evaporation case to get final product, just form a Fast Heating district in the evaporation tank; And after electric boiling plate energising heating, a small amount of water can obtain Fast Heating in the evaporation tank, can produce high-temperature steam because evaporation tank is inner simultaneously, thereby so that the air pressure in the evaporation tank is relatively higher than the air pressure in the storage tank, thereby can keep the water level in the evaporation tank to be lower than the interior water level of storage tank, more be conducive to the water in the Fast Heating evaporation tank, thereby produce fast a large amount of steam, then a little steam are entered the cooking chamber heat food by the steam mozzle; Simultaneously in the heating process, Fast Heating district in the evaporation tank produces heat, fraction conducts to through overheated that water temperature rises in the water-containing area that the storage tank zone makes storage tank, heat insulation rubber ring lower end has water inlet, water temperature in the water-containing area zone of storage tank constantly rises through overheated conduction, warm water adds to the Fast Heating district through heat insulation rubber ring lower end water inlet continually, and the thermal efficiency is corresponding raising also.
Although electric hot plate is when the energising heating, need not heat the water in the whole storage tank, and the water that only need to heat in the storage tank gets final product, but in the time of long-term, also can produce a small amount of steam in the storage tank, condensate return mouth on the water tank outer cover of the present invention can reflux the condensed water that produces after the steam process cooking chamber condensation that produces in the storage tank, from newly getting back to storage tank.
In addition, when the water level in the storage tank surpassed the water level of a setting, the tongue tube in the storage tank can detect this signal, thereby is connected to external warning circuit, and reminding user in time adds water to storage tank.
