Delicate structure of the present invention, can not occupy the space of pot body, effectively ensures the available space of pot body; The present invention by three grades of froth breaking measures, effectively prevents bubble from overflowing, cleaner on using, more save worry; In addition, without the need to arranging electricity component in lid of the present invention, therefore compared to other structures, the present invention uses safer, stable, there will not be the potential safety hazard such as open circuit, short circuit; Thus there is longer service life, stronger competitiveness.
As preferably, described antifoam meter is hollow-core construction, and the aperture of antifoam meter is 0.5-1.5mm; Hollow antifoam meter easily produces siphonage, and when bubble contact antifoam meter, the local of bubble is sucked by antifoam meter and rapid in antifoam meter internal slide, therefore bubbles burst, and this structure effectively can improve defoaming effect.
As preferred further, the aperture, upper end of described antifoam meter is large, aperture, lower end is little; So that moisture film is torn in the process risen along antifoam meter inwall, thus promote defoaming effectiveness.
As preferably, at the outward flange of described hard orifice plate, ringwise guiding gutter is also installed, the sidewall that described guiding gutter is connected with hard orifice plate offers pod apertures; The soup juice part flowed down after bubbles burst remains on hard orifice plate, and this guiding gutter can, by soup juice fast guiding, make it flow back in pot body; Meanwhile, when opening lid, described guiding gutter can effectively prevent the soup juice on lid from flowing to limit wall along lid, polluting pot external body.
