Abstract

The invention discloses an anti-spilling cover for cooking porridge. The anti-spilling cover is composed of an outer cover, an inner cover and backflow holes, wherein the outer cover is a recessed circular ring of which the outer part is high and the inner part is low; the backflow holes are formed in the edge of an inner ring of the outer cover; the inner cover is a hollow ball made of a light material; when air pressure in a pot rises to a certain value, the inner cover is lifted, and the outer cover is not lifted; after the inner cover is lifted, water steam in the pot is condensed to form small water drops, and the air pressure in the pot drops accordingly; when the air pressure drops to a certain value, the inner cover automatically returns into the inner ring of the outer cover, so that the inner cover and the outer cover are closed, and the air pressure in the pot gradually rises; the porridge spilled over the inner cover and the outer cover flows back into the pot through the backflow holes. The anti-spilling cover for cooking the porridge has the beneficial effects that the energy is saved, the effect is improved, and the time and the labor are saved.

Description

To cook congee overflow preventing lid

Technical field

The present invention relates to a kind of kitchen articles, particularly one is cooked congee overflow preventing lid.

Background technology

Congee because of easily digestion and extremely people like, especially various health care congee, if maize gruel, red bean porridge etc. are more by the favor of numerous the elderly, the pot but this kind of starchy food of cooking congee very easily overflows, not only run off nutriment, also the kitchen range top is made into a mess, even put out gas burner, pot cover is pushed away and falls on the ground.

Summary of the invention

In order to effectively overcome the drawback of excessive pot of cooking congee, the invention provides one and to cook congee overflow preventing lid, its structure is simple, is beneficial to cleaning, easy to use, easily promotes.

The present invention's overflow preventing lid of cooking congee is made up of enclosing cover, inner cap and return port; Enclosing cover is high outside and low outside up concave type annulus, and its inner annular edge has return port; Inner cap is the hollow ball be made up of light material, and when pot internal gas pressure rises to certain value, inner cap is just raised, and enclosing cover can not be raised; After inner cap is raised, in pot, steam meets the cold water droplet that diminishes, and pot internal gas pressure declines thereupon, and when air pressure is down to certain value, inner cap automatically resets, and rolls back in the inner ring of enclosing cover, and inner cap and enclosing cover are closed, and pot internal gas pressure is cumulative, ensures efficiency of cooking congee; Overflow in inner cap and the congee soup that covers outward and can be flowed back in pot by return port.

The cook congee beneficial effect of overflow preventing lid of the present invention is energy-conservation, synergy, saves time and laborsaving.

Detailed description of the invention

Embodiment one

The present invention's overflow preventing lid of cooking congee is made up of (as shown in Figure 1) enclosing cover 1, inner cap 2 and return port 3; Enclosing cover 1 is high outside and low outside up concave type annulus, and its inner annular edge has return port 3 (as shown in Figure 2); Inner cap 2 is the hollow balls be made up of light material, and when pot internal gas pressure rises to certain value, inner cap 2 is just raised, and enclosing cover 1 can not raise (as shown in Figure 3); After inner cap 2 is raised, in pot, steam meets the cold water droplet that diminishes, and pot internal gas pressure declines thereupon, when air pressure is down to certain value, inner cap 2 automatically resets, and rolls back in the inner ring of enclosing cover 1, inner cap 2 is closed with enclosing cover 1, and pot internal gas pressure is cumulative, ensures efficiency (as shown in Figure 4) of cooking congee; The congee soup overflow on inner cap 2 and enclosing cover 1 can flow back to (as shown in Figure 1) in pot by return port 3.

Claims

1. cook congee overflow preventing lid, the overflow preventing lid that it is characterized in that cooking congee is made up of enclosing cover (1), inner cap (2) and return port (3); Enclosing cover (1) has return port (3) for high outside and low outside up concave type annulus, its inner annular edge; Inner cap (2) is the hollow ball be made up of light material, and when pot internal gas pressure rises to certain value, inner cap (2) is just raised, and enclosing cover (1) can not be raised; After inner cap (2) is raised, in pot, steam meets the cold water droplet that diminishes, pot internal gas pressure declines thereupon, when air pressure is down to certain value, inner cap (2) automatically resets, and in the inner ring of enclosing cover of rolling back (1), inner cap (2) is closed with enclosing cover (1), pot internal gas pressure is cumulative, ensures efficiency of cooking congee; The congee soup overflow on inner cap (2) and enclosing cover (1) can pass through return port (3) and flow back in pot.
