Abstract

The utility model relates to an anti-burnt earthen pot, which comprises a side wall and a bottom wall, wherein the middle part of the bottom wall is provided with an upwards convex heating power concentration bottom surface; the utility model utilizes the heat convection phenomenon of the liquid to increase the force of the heat convection, so that the food materials in the marmite move simultaneously along with the liquid in the marmite, and the food materials in the marmite are uniformly heated, thereby avoiding or reducing the occurrence of the phenomenon of pot burnt; the heat concentration bottom surface can guide flame to gather at the center of the marmite to form local heat concentration, so that the bottom of the marmite is poor in heated heat, when the center of the bottom of the marmite is locally heated, the density of liquid at the position is reduced, the liquid rises, cold liquid at other positions is supplemented, and the circulation of the liquid in the marmite is promoted.

Description

Burnt-proof earthen pot

Technical Field

The utility model relates to a prevent sticking with paste pot marmite.

Background

The earthen pot is a traditional cooker in China, and is deeply popular with Chinese people because of the characteristics of air permeability, adsorptivity, uniform heat transfer, slow heat dissipation and the like. The traditional earthen pot is made up by using quartz, feldspar and clay as raw material and making them be compounded into ceramic product, and making them pass through the process of high-temp. firing. The earthen pot can transmit external heat energy to the internal raw materials uniformly and durably, the relative balanced environment temperature is favorable for the mutual permeation of water molecules and food, the longer the mutual permeation time is maintained, the more the fresh and fragrant components overflow, the fresher and mellow the taste of the stewed soup, and the crisper and more the texture of the stewed food.

However, the earthen pot also has a prominent defect that the earthen pot is easy to be burnt due to the characteristics of slow boiling with small fire and relatively slow heat conduction. The user needs to stir continuously, which brings much inconvenience to the user.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem of providing a pot marmite is prevented sticking with paste of difficult pot when using.

The utility model adopts the technical proposal that: an anti-burnt earthen pot comprises a side wall and a bottom wall, wherein the middle part of the bottom wall is provided with an upwards convex heating power concentration bottom surface.

The bottom surface is concentrated to heating power is the arc.

The utility model discloses the upper surface of bottom surface is concentrated to heating power is provided with arch or sunken.

The arch or the recess of the utility model is arc-shaped.

The thickness of the side wall of the utility model is gradually reduced from the pot mouth to the pot bottom.

The utility model discloses an actively the effect does: the phenomenon of pot burnt is caused because food materials in the pot are deposited at the bottom of the earthenware pot and are heated at the bottom part all the time, so that the phenomenon of pot burnt is caused. The principle of this patent has utilized the thermal convection phenomenon of liquid, and the dynamics of increase thermal convection makes the edible material in the marmite follow the liquid simultaneous movement in the marmite, makes the edible material thermally equivalent of marmite the inside to reach and avoid or alleviate the emergence of sticking with paste a pot phenomenon. The heat concentration bottom surface can guide flame to gather at the center of the marmite to form local heat concentration, so that the bottom of the marmite is poor in heated heat, when the center of the bottom of the marmite is locally heated, the density of liquid at the position is reduced, the liquid rises, cold liquid at other positions is supplemented, and the circulation of the liquid in the marmite is promoted. Under the action of circulation, the food materials are driven to do circulation movement, and the whole body is uniformly heated, so that the phenomenon of pot pasting is avoided.

Detailed Description

As shown in the accompanying drawing 1, the utility model discloses a lateral wall 1 and diapire 2, the diapire of traditional marmite is planar form, in order to solve the problem that traditional marmite pastes the pot easily, the utility model discloses set up on diapire 2 of marmite and upwards be the bellied heating power of arc and concentrate bottom surface 3, guide flame gathering is at the center of marmite, form local heating power and concentrate, thereby the temperature that makes 2 middle parts of diapire is higher than the temperature on 2 outer edges of diapire, it is poor to make the marmite bottom cause the heat of being heated, promote the interior liquid of marmite and form the circulation (as arrow in figure 1) and show, under the effect of circulation, eat the material and be driven and also do the circulation motion, make whole thermally equivalent, avoid the phenomenon of pasting the pot.

The arc-shaped bulge 4 or the arc-shaped depression are arranged on the upper surface of the heat concentration bottom surface, so that the heating area of the bottom of the marmite is increased, the formation of distribution heat concentration is further promoted, the difference of the heated heat at the bottom of the marmite is more quickly caused, and the formation of liquid circulation in the marmite is promoted.

The thickness of the side wall 1 gradually decreases from the pot opening to the pot bottom, the wall thickness of the top of the side wall is the largest, the heat conduction is slow, the side wall gradually becomes thinner downwards, the heat conduction efficiency is gradually improved, the thermal difference between the upper part and the lower part of the marmite can be formed, and the formation of liquid circulation in the marmite is promoted.

The utility model discloses make liquid form the circulation in the marmite, under the effect of circulation, eat the material and be driven and also do the circulation motion, holistic being heated more evenly to the phenomenon of sticking with paste the pot has been avoided.

The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the embodiments of the present invention.
