Abstract

The utility model discloses an anti-overflow pan cover, belonging to the field of cooker used for kitchen. The utility model is designed for the problems and disadvantages that the prior pan cover can not prevent water or bubble from overflowing out, the structure of the prior pan is complex, and the manufacturing cost is high. The inner surface of the anti-overflow pan cover is concave, and a permeability-hole is provided on the pan cover, and a reflux hole is provided on the portion under the permeability-hole and along the pan cover. When the anti-overflow pan by the utility model is utilized, the deflation can be done through the reflux hole and the permeability-hole which are provided on the pan cover when the air pressure inside the pan reaches the stated critical-state, thereby the effect of pressure-reducing and anti-overflow can be achieved. The inner surface of the pan is concave, thereby the soup can be made effectively to reflow to the pan afresh, and even though the soup overflows from the reflux hole, the overflowing soup can also reflow to the pan through the reflux hole. So compared with the prior pan cover and the prior anti-overflow pan cover, the anti-overflow pan cover related by the utility model has a simple structure and a low manufacturing cost, and the overflow can be prevented effectively. The utilization is convenient, and the utility model can be applied widely to the processes of porridge-boiling, soup-simmering and the like.

Description

Anti-overflow pot cover

Technical field

The utility model relates to the cooker that is used for the kitchen, relates in particular to pot cover.

Background technology

At present, pot commonly used comprises the pot body that is used to hold food such as congee and covers pot cover on the pot body in the people life, this pot is being cooked congee or during Baoshang, because pot cover can not prevent that materials such as sealing or foam overflow, the material permanent current that overflows is on the pot body or the kitchen range top, and it is pretty troublesome to cause pot body and the kitchen range top to clean.

In order to solve the problem of overflowing, people have designed anti-overflow pot cover.Usually, anti-overflow pot cover adopts the mode of exhaust step-down, and several air-vents are set on pot cover, and is equipped with vinyl cover and solves above-mentioned overflow problem.

But the complex structure of above-mentioned anti-overflow pot cover, production cost is higher.

The utility model content

The purpose of this utility model is to solve existing pot cover can not prevent that sealing or foam overflow, and existing anti-overflow pot cover complex structure, and production cost problem of higher and deficiency provide a kind of simple in structure, and production cost is lower, and can effectively prevent the anti-overflow pot cover that overflows.

For addressing the above problem, the utility model adopts following technical scheme: the inner surface of this anti-overflow pot cover is a concave surface, and pot cover is provided with air-vent, is provided with return port at described air-vent along the downward position of pot cover.

According to above-mentioned technical solutions of the utility model, this anti-overflow pot cover when the air pressure in the pot reaches certain critical condition, can be exitted by the air-vent and the return port that are arranged on the pot cover in use, plays the effect of step-down anti-overflow; The pot cover inner surface is a concave surface, can make soup juice flow back in the pot again effectively; Even have soup juice to overflow, also can flow back in the pot by return port by air-vent.So, to compare with anti-overflow pot cover with existing pot cover, anti-overflow pot cover described in the utility model is simple in structure, and production cost is lower, can prevent from effectively to overflow, and easy to use.

The specific embodiment

Below in conjunction with accompanying drawing, further specify technical characterictic of the present utility model and function characteristics, purpose is that the utility model can be described better, but is not to be used for limiting protection domain of the present utility model.

Referring to figs. 1 through Fig. 8, the inner surface of anti-overflow pot cover 1 described in the utility model is a concave surface, and pot cover is provided with air-vent 2, is provided with return port 3 at described air-vent along the downward position of pot cover.

For the better effects if that anti-overflow refluxes, above-mentioned return port 3 is arranged on the lower edge of described pot cover 1.

Above-mentioned air-vent can be triangle, rhombus and/or multiple geometry such as quincunx.

The preferred 3-5mm of above-mentioned air-vent diameter, number can be with different preferred 3-15 of shape.

Above-mentioned return port is preferably semicircular breach, the preferred 8-12mm of diameter, and number can be individual with the preferred 3-9 of the size of diameter.

More even in order to be heated, above-mentioned return port is a wave-shaped gap, i.e. the edge undulate of breach, wave-shaped gap diameter are between 3-12mm, and number is 3-50.

Adopt the anti-overflow pot cover behind the said structure, when the air pressure in the pot reaches certain critical condition, can exit, play the effect of step-down anti-overflow by being arranged on the air-vent on the pot cover and the return port at edge; The pot cover inner surface is a concave surface, can make soup juice flow back in the pot again effectively; Even there is soup juice to overflow, also can flows back in the pot, thereby prevent from effectively to overflow by the return port at edge by air-vent.This anti-overflow pot cover is simple in structure, production cost is lower, easy to use, anti-overflow is effective.

The above-mentioned specific embodiment is illustrated the utility model with preferred embodiment, but the example of this visualization of just lifting for the ease of understanding should not be considered to be the restriction to the utility model scope.Equally, according to the description of the technical solution of the utility model and preferred embodiment thereof, can make various possible being equal to and change or replacement, and all these changes or replacement all should belong to the protection domain of the utility model claim.
