Description

Container cover and heating vessel

Technical field

The utility model relates to household appliance technical fields, more specifically, are related to a kind of container cover and heating vessel.

Background technique

Existing major part heating vessel, for example health-promotion kettle or insulating pot are when realizing anti-overflow, are all to detect Suspend heating when will overflow, and is further continued for heating after waiting foams decline, but this structure cannot keep during heating The constantly boiling of cooked material extends the Production Time of entire food materials to reduce the mouthfeel of food materials.

Therefore, how to propose that a kind of container cover including new anti-overflow mode and the heating of the liquid including the container cover are held Device becomes current urgent problem to be solved.

Utility model content

The utility model aims to solve at least one of the technical problems existing in the prior art.

For this purpose, a purpose of the utility model is, a kind of container cover is provided.

Another of the utility model is designed to provide a kind of heating vessel including said vesse lid.

To achieve the above object, the embodiment of the utility model first aspect provides a kind of container cover, for liquid plus Heat container, heating vessel include container body, wherein container cover includes: lid, can be covered on container body, on lid It is provided with air intake and steam drain, and steam drain is connected to air intake；Opening and closing part is mounted on lid, can be opened and closed Steam drain；Wherein, the sum of area of air intake is S1, and the sum of area of steam drain is S2, and S1 >=S2 and/or 250mm²≤S2 ≤1500mm²。

The container cover that embodiment according to the present utility model provides, can be insulating pot, electric water-heating cup or health-promotion kettle etc., specifically Ground, heating vessel includes container body and container cover, and container cover includes lid and opening and closing part, and lid is for realizing container The opening and closing of body, and opening and closing part can open and close steam drain, in this way at the initial stage of heating vessel heating, can lead to It crosses opening and closing part and closes steam drain, so as to shedding for the heat of product during heating be reduced, to can ensure that heating effect Rate.Meanwhile can also be opened steam drain before product will overflow by opening and closing part, so that the steam in container can be arranged Out, it can prevent heating vessel from overflowing in this way, and after steam drain opening, the food materials of container body can continue Heating does not need to stop heating while realizing anti-overflow, here so that the food materials inside heating vessel just can It is gradually heated by the sonochemical activity to boiling, product is just made to be able to maintain the constantly boiling of cooked material during heating in this way, so as to Ensure the mouthfeel of cooked material, improve heating efficiency, reduces heating time.There are also this kind of structures only to need in existing lid On the basis of interconnected steam drain and air intake are set, opening and closing part is then arranged at steam drain can be realized product and is overflowing Automatically opening before, it is intelligent anti-overflow so as to simply, easily realize.And the sum of area of air intake S1 is more than or equal to row Steam just can be gathered in more quickly appearance so that being greater than leaving area into vapour area by the sum of area of steam ports S2 in this way At device lid, so as to improve velocity of exhaust.And the sum of area of one or more steam drains S2 is more than or equal to 250mm²It is less than Equal to 1500mm², so that the area of steam drain is more moderate, it can ensure displacement of the container cover within the unit time in this way, To can ensure that the steam discharge efficiency of product, so that product is less susceptible to overflow.

Wherein, the quantity of steam drain and air intake can also be multiple to may be either one, and steam drain can increase to be multiple The area of big steam drain improves the velocity of exhaust of steam, and air intake is capable of increasing to be multiple into vapour area, improves into vapour speed Degree.
