Description

a poly oil pan

technical field

The utility model belongs to the field of kitchen cooking utensils, in particular to an oil collecting pan.

Background technique

At present, the pots commonly used by people are generally divided into two types according to the shape of the bottom of the pot body. One is a pot with an arc-shaped bottom, and the other is a pot with a horizontal bottom. Usually, the pot with a horizontal bottom is used with an induction cooker. .

As shown in Figure 1, the thickness of the bottom of this pan is of equal thickness, that is, the thickness of the bottom is the same everywhere. When the ordinary pan is heated, the inside of the pan will bulge upward or sink downward, especially the aluminum alloy with a composite bottom. For the frying pan, due to the inconsistency between the materials of the aluminum alloy and the compound bottom material (ferritic stainless steel such as stainless steel 430 or stainless steel 410), the thermal expansion coefficients of the two materials are inconsistent when the pan body is heated (50-400°C). Since the thermal expansion coefficient of the aluminum alloy is greater than that of the composite bottom material, the pot body expands or shrinks and deforms when heated, and the pot body, especially the bottom area, is under the action of heat, and the inner and outer surfaces of the pot bottom will gradually arch toward the inner surface of the pot. , causing the bottom to be uneven. As the temperature rises, the arched surface becomes larger, as shown in Figure 2, causing the oil at the bottom of the pot to run sharply to both sides under the heating state, that is, the phenomenon of oil running becomes more serious and gathers in the pot. The edge of the bottom and the middle of the bottom of the pan are in an oil-free state, and it is very easy to burn the food during cooking.

Chinese patent CN201234915 discloses a "stainless iron pot with less oily fume", which has a circular arc bottom inside the pot body and a flat bottom outside the pot body. The stainless iron pan with less oil fume can be used on an induction cooker, and can solve the problem that oil does not spread to the periphery, so that food is not easy to burn and stick to the pan, and has less oil fume. However, in actual production, it is difficult to achieve a completely flat bottom structure, and it is easy to spin when placed on an induction cooker. It is necessary to form an upwardly arched outer arc surface on the outside of the bottom of the pot. The arc structure also needs to add an upwardly arched bottom concave on the outer side of the bottom, which greatly increases the processing difficulty of the pot body, especially the processing difficulty of the pot bottom. If the thickness of the bottom of the pot is increased and an upwardly arched arc surface is turned on the outside of the bottom of the pot to form a bottom concave, the transition of the arc surface is not smooth and even, not only the appearance is greatly reduced but also the pot body is heated unevenly, which affects the cooking effect. And the pot body in the present invention is made up of iron pot body, aluminum material and magnetic conduction outer bottom, and three parts adopt high-tonnage press to remake and synthesize or connect through high-frequency brazing, and consumers find that it is easy to take place after long-term use. Bottom phenomenon, the connection between the pot body and the bottom of the pot is not firm enough, which greatly shortens the service life of the pot.

Therefore, in actual production, no processing method for a pot that neither rotates on the horizontal surface nor leaks oil has been conceived yet.

Utility model content

In order to overcome the deficiencies of the prior art, the utility model provides an oil-gathering frying pan which can be placed stably, can effectively solve the problem of oil leakage, and has a good cooking effect.

The technical scheme adopted by the utility model to solve the technical problem is: an oil-gathering pan, including a pan body, the inside of the bottom of the pan body is provided with a downwardly recessed first arc surface structure, and the outside of the bottom of the pan body is provided with upward protrusions The second arc surface structure. The first curved surface structure makes the oil in the pot always gather at the bottom of the pot no matter whether it is cold or heated, and no oil leakage will occur, which effectively improves the cooking effect; the setting of the second curved surface structure prevents the pot body from Rotating on the heating surface of the induction cooker improves the stability of heating.

Further, a pot bottom is provided outside the bottom of the pot body, and the second arc surface structure is provided on the lower surface of the pot bottom. The pot body and the pot bottom are of split structure, which reduces the manufacturing cost and simplifies the processing technology.

Further, the pot body is formed by oil pressure at one time. The oil pressure forming process changes the density of the aluminum plate at the bottom of the pot body, thereby changing the thermal expansion coefficient of the pot body.

Further, the pot body and the bottom of the pot are connected by heat re-beating. The pot body and the bottom of the pot are tightly connected to prevent the bottom from falling off, and the thermal conductivity is improved, the heat conduction efficiency is higher, and the food is heated more evenly during cooking.

Further, the depth of the first arcuate structure is T1, the height of the second arcuate structure is T2, and 0.5≤T1≤3.0mm. It is ensured that when the bottom of the pot is arched towards the inner surface in the heated state, there is always an inner arc surface at the bottom of the pot, that is, the first arc surface structure, to realize the function of oil accumulation.

Further, in a heated state, the depth of the first arcuate structure is T1', the height of the second arcuate structure is T2', and T2'<T1. Ensure that T1-T2'>0, so that the first arc surface structure will not disappear due to arching in the heated state, and the purpose of oil in the pot always gathering at the center of the bottom of the pot is realized.

Further, said 0.1≤T1'≤2.9mm. Guarantee the function of oil accumulation and avoid oil leakage.

Further, said 0.1≤T2'≤0.4mm.

Further, the thickness of the bottom center of the pot body is 3.0-6.5 mm. This thickness design reduces the amount of oily smoke generated during cooking, increases thermal deformation stability, and heats more evenly, which is more energy-saving and environmentally friendly.

The beneficial effect of the utility model is that the structure is simple, it will not rotate when placed on the electromagnetic cooker, and no oil will escape when heated, and the oil will always be gathered in the first arc surface structure of the pot body, and the cooking effect is good.
