The utility model content
At above-mentioned the deficiencies in the prior art, the utility model provides a kind of electric steamer of energy instantaneously producing steam.
The technical solution of the utility model is: a kind of electric steamer of instantaneously producing steam, comprise base, be installed in water container on the base, be installed in the food steamer drawer on the water container and be installed in pot cover on the food steamer drawer, the bottom of water container is equipped with heating plate, the bottom of heating plate be provided with around electrothermal tube, corresponding heating plate is equiped with the steam guard shield in the water container, the steam guard shield is the double-decker with lateral wall and madial wall, zone between lateral wall and the madial wall is a boiling-house, the corresponding electrothermal tube setting of boiling-house.The zone that the inwall of madial wall surrounds is an isolation ward.
The lateral wall of above-mentioned steam guard shield is connected with the madial wall top, and the top of lateral wall is provided with the steam flow-guiding channel, and the bottom is provided with the breach of the circulation of supplying water.
Above-mentioned water container inner bottom part is provided with the position limiting structure that limits the steam guard positions, prevents the skew of steam guard shield occurrence positions, leaves the zone of heating plate.
Above-mentioned position limiting structure is round boss, annular ridge, circular groove or annular groove.
Above-mentioned steam guard shield is parts independently, or one-body molded with water container.
The utility model is because the steam guard shield adopts double-decker, the zone that will add hot water is divided into relatively independent boiling-house and isolation ward, make the volume of boiling-house be contracted to effective thermal treatment zone directly over the electrothermal tube, be the highest zone of heating degree on the heating plate, first, minimizedly add the hot water amount, shorten the steam generation time, even second the heating plate size becomes big, the volume of boiling-house and the size of electrothermal tube are complementary, and can not reduce the efficiency of heating surface.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
Referring to Fig. 1, the present embodiment electric steamer comprises: water container 2, dress that base 1, dress are arranged on the base are arranged on the food steamer drawer 5 on the water container and adorn the pot cover 6 that is arranged on the food steamer drawer, the bottom of water container 2 is equipped with the heating plate 3 of slab construction, be used for the water of water container is heated generation steam, the bottom of heating plate 3 is provided with the electrothermal tube 31 of two heating usefulness, electrothermal tube 31 encompasses circle, therefore the central area heating degree of heating plate 3 is lower, exterior lateral area heating degree higher (showing as Fig. 2).
Be provided with the double-deck steam guard shield 4 of cylindricality in the water container 2, steam guard shield 4 be positioned at heating plate 3 directly over.Show as Fig. 3, Fig. 4, steam guard shield 4 includes lateral wall 43 and the madial wall 44 that the top is connected, the top of lateral wall 43 is provided with some steam flow-guiding channels 41, the bottom of lateral wall 43 is provided with the breach 42 of the circulation of supplying water, distance between madial wall 44 and the lateral wall 43 is by the size decision of electrothermal tube 31, promptly with heating plate 3 on the higher exterior lateral area width of heating degree be complementary, the central area size that heating degree is lower on the internal diameter size of madial wall 44 and the heating plate 3 is complementary.
Lateral wall 43 is divided into two parts in the storage area and the thermal treatment zone with water container 2 inner spaces, and the storage area is the space of steam guard shield outside, and the thermal treatment zone is a steam guard shield volume inside; Madial wall 44 is divided into boiling- house 7 and 8 two rooms of isolation ward with the thermal treatment zone, and boiling-house 7 is the space between madial wall 44 and the lateral wall 43, the higher exterior lateral area of heating degree on the heating plate 3, and heating is fast; Isolation ward 8 is the space within the madial wall 44, and the lower central area of heating degree on the heating plate 3 is heated slower.
In order to prevent the skew of steam guard shield 4 occurrence positions, leave the zone of heating plate, the outside of the corresponding heating plate 3 of water container 2 inner bottom parts is provided with the position limiting structure 21 that projects upwards, and lateral wall 43 holdings of steam guard shield 4 are in the outside of position limiting structure 21.
The round boss of position limiting structure 21 for projecting upwards in the present embodiment, also can be designed as the fin of a circle annular, or to recessed circular groove, annular groove, can play and limit the steam guard positions, make the steam guard shield to be positioned at effect directly over the heating plate.
Present embodiment utilizes the steam guard shield, the water yield of heating is reduced to minimum, and in the extremely short time, the water in the boiling-house 7 just can be heated to boiling generation steam like this, and heat by the article in 41 pairs of food steamer drawers 5 of steam flow-guiding channel.
When the water yield in the boiling-house 7 reduced, the water of storage area replenished by breach 42 slow inflows of lateral wall bottom, avoids the dry combustion method phenomenon to take place.
The madial wall 44 of steam guard shield is that non-tight cooperates with the bottom of water container 2 in the present embodiment, so just can guarantee the dry combustion method phenomenon can not take place in the isolation ward 8.In order to reach this purpose, same, also the bottom of madial wall 44 is provided with the breach that supplies water and circulate again.
Steam guard shield 4 is parts independently in the present embodiment, also can be designed as with water container 2 one-body molded.
Heating plate 3 is circular, electrothermal tube 31 around forming circle in the present embodiment, so the lateral wall 43 of steam guard shield, madial wall 44 all are designed to annular.According to different product demands, it is square around forming to be designed to square, electrothermal tube as heating plate 3, and the lateral wall 43 of steam guard shield, madial wall 44 preferably also are designed to corresponding square.
As other occupation modes, in use the consumer, also can take out the steam guard shield in the water container 24 when thinking mutton cooked in a chafing pot, stew or other food according to the needs of oneself, this moment, the space of water container just became big, can satisfy mutton cooked in a chafing pot or steam the needs of stewing other foods.
