Referring to shown in accompanying drawing 1, accompanying drawing 2, the present embodiment includes base 1, electro-heat equipment 2, middle seat 3, container 4, upper lid 5, interior Cavity provided with dress water in lid 6, middle seat 3, container 4 is placed in middle seat 3, and electro-heat equipment 2 is arranged on the bottom of middle seat 3, upper lid 5 On middle seat 3 or base 1, the inner chamber of upper lid 5 and middle seat 3 forms heating chamber.

Inner cap 6 is the lid of lower ending opening, and inner cap 6 is placed in heating chamber and coats container 4.Steam heater is in work When, vapor is gathered in intracavitary to heat the food in container 4 by inner cap 6, the temperature of intracavitary is lifted rapidly, can effectively be dropped The temperature rise of lid 5 in the energy consumption of low steam heater, reduction, and reduce the excessive of condensed water.

Inner cap 6 is by heating chamber at intervals of heating bore 7 and heating exocoel 8.When electro-heat equipment 2 works, first in heating Vapor is produced in chamber 7, vapor is largely retained among heating bore 7, and to heat food, a small amount of vapor is spilt into Heat in exocoel 8.

Heating exocoel 8 mainly plays a part of heat-insulation and heat-preservation, when the temperature in heating bore 7 is too high or steam is too high When, there will be part vapor to flow into heating exocoel 8 from heating bore 7, and it is that upper lid 5, middle seat 3 and inner cap 6 are surrounded to heat exocoel 8 One closing space, relatively good heat insulation effect can be played to heating bore 7.

Now the temperature of heating exocoel 8 is lower than the temperature of heating bore 7, and the heating radiating of exocoel 8 is that a comparison is slow Process.So that the temperature rise of upper lid 5 is relatively low, being touched up with hand will not also feel hot, it is possible to prevente effectively from consumer is high The upper lid 5 of temperature is scalded, and adds the security of product.

It is fewer for due to heating the vapor in exocoel 8 compared with the prior art, it is possible to avoid because water steams Gas is more and assembles a large amount of globules by Water vapor condensation in the junction of upper lid 5 and middle seat 3, it is to avoid the globule passes through upper lid 5 leak into outside product with the fit clearance of middle seat 3, it is to avoid table top ponding.Also will not because of the globule along in seat 3 housing exterior walls The place that socket and plug is connected is flow to, generation electric leakage hidden danger is effectively prevent.

Vapor is largely isolated in heating bore 7 by inner cap 6, even if there is a small amount of vapor to run out of, also can only be The inwall of upper lid 5 forms a small amount of globule, is not enough to flow to the outside of product.

Container 4 is placed in heating bore 7, is conducive to heating food more quickly.
