Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and examples:
as can be seen from FIGS. 1-5, an anti-overflow structure of an electric rice cooker comprises: a face cover 1 and an inner cover 3; a steam port sealing ring 2 is arranged on the surface cover 1; the inner cover 3 is provided with an inner cover lining 4;
an opening is formed above the steam port sealing ring, the bottom of the steam port sealing ring is provided with an air inlet 5, and the upper part of the steam port sealing ring is provided with an air outlet 6;
the air outlet 6 comprises a front air outlet 61 and a rear air outlet 62; the rear outlet port 62 is a return port;
the cross-sectional area of the front air outlet is larger than that of the rear air outlet;
the two sides of the front air outlet are provided with inverted splayed retaining ribs 7;
the end part of the inverted splayed blocking rib 7 is connected with one end of a linear blocking rib 8, and a gap is formed between the other end of the linear blocking rib 8 and the side wall 10 of the sealing ring;
the distance between the free end of the straight-line-shaped blocking rib and the side wall of the sealing ring is less than 5 mm.
The distance between the front air outlet and the side wall of the steam port sealing ring is larger than the distance between the rear air outlet and the side wall of the steam port sealing ring.
The steam port sealing ring is divided into a front sealing cavity and a rear sealing cavity by the splayed blocking rib and the linear blocking rib; the volume of the rear sealed cavity is larger than that of the front sealed cavity.
The splayed blocking rib and the straight blocking rib separate the air outlet from the rear air outlet.
The splayed blocking rib and the linear blocking rib form a bubble breaking blocking rib 9.
The side wall of the steam port sealing ring is funnel-shaped (cone-shaped), and the cross section is gradually reduced from top to bottom.
The included angle of the inverted splayed retaining ribs on the two sides of the front air outlet is 50-80 degrees.
The length of the straight-line-shaped blocking rib is one third to one fourth of the length of the steam port sealing ring.
The free end of the straight-line-shaped blocking rib is conical, and the cross sectional area of the front end is smaller than that of the rear part.
Ensuring that water vapor flows out from the front air outlet preferentially; the distance between the bubble breaking blocking rib and the side wall of the sealing ring is less than 5mm, and bubble breaking is realized by reducing the flow gap; steam flows from the preceding gas outlet, keeps off the muscle effect because of breaking the bubble and flows to left and right both sides, and the bubble is kept off the muscle and is realized breaking the bubble and become liquid back because of the width diminishes when the sealing washer lateral wall passageway through breaking the bubble, goes out from the gas outlet backward flow after again. The steam port sealing ring is made of materials such as steam-resistant silica gel and rubber.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the structure of the present invention in any way.
