Definitions
- the invention relates to a non-smoke non-stick pan, in particular to an inner pot and an outer pot, the upper end of the inner pot and the outer pot is fixedly connected, and the non-oil smoke is not sticky between the inner pot and the outer pot. pot.
- this pot In order to achieve no fumes, and do not stick to the food, this pot must solve two problems, one is that the pot body should be heated evenly, and the temperature is lower than 240 degrees Celsius, which is the consensus of the pot industry, it is not easy to heat the pot evenly. Produce the sticking phenomenon. If the temperature in the pot does not exceed 240 degrees Celsius, no fumes will be produced. Because the general cooking oil only has its oil temperature exceeding 240 degrees Celsius, some volatile substances in the oil will volatilize and form soot.
- the existing gas furnace generally has an inner ring fire and an outer ring fire. The fire condition of the pan reflected in the pot is as shown in Fig.
- the Chinese patent literature discloses a no-smoke wok (patent application number 02216371.9; The application date is March 26, 2002), including the pot body, the pot body is composed of the inner pot body and the outer pot body, the upper and the outer pot body are fixedly connected, and the inner pot body and the outer pot body have mutual mutual Corresponding flat bottom, the inner pot body and the flat bottom of the outer pot body are integrated into one body, and an empty layer is formed between the inner and outer pot body walls.
- the non-steamed wok relies on the flat bottom of the inner pot body and the outer pot body to form an integrated structure, and the inner and outer pot body forms an empty layer between the pot walls, and is expected to solve the problem of no fumes and non-stick pans.
- the temperature difference between the bottom of the pot and the edge of the pot is also quite large; there is still a problem in the pot, that is, the flat bottom portion of the pot must reach a certain thickness to have the effect of storing heat, the flat bottom portion of the pot is too thick, and the weight of the pot It is heavy, making it inconvenient to use.

- the heat conducting member is a cylinder
- the number of the cylinders gradually changes from lean to dense from the bottom of the pan to the edge of the pan, and the diameter of the cylinder gradually changes from fine to coarse from the bottom of the pan to the edge of the pan.
- the heat conducting member is a mesh member (in the form of a grid), and the meshes of the mesh members are provided with mutually communicating grooves for air convection, and the density of the mesh From the bottom of the pot to the edge of the pot gradually changes from thin to dense.

- the inner wall is in point contact or line contact, and the number of contact points of the heat conducting member or the number of contact lines gradually changes from lean to dense from the bottom of the pan to the edge of the pan, so that the high temperature of the bottom of the pan can be quickly changed by changing point contact or line contact. It is transferred to the edge of the pot to achieve the same purpose of the temperature at the bottom of the pot and the edge of the pot.
- the temperature in the pot is controlled below 240 degrees Celsius, the non-stick pan can be realized without the purpose of soot.
- Figure 1 is a cross-sectional structural view showing an embodiment of the present invention.
- Fig. 2 is a top plan view showing an embodiment of the outer layer of the outer pot after removing the inner pot of the present invention.
- Fig. 3 is a top plan view showing another embodiment of the outer pot of the outer pot after removing the inner pot of the present invention.
- Figure 4 is a schematic view of the structure of Figure 2 after removing the heat conductive member of the bottom of the pot.
- Figure 5 is a schematic view showing the structure of Figure 3 after removing the heat conductive member of the bottom of the pot.
- Fig. 6 is a schematic view showing the state of heating of the prior art pot.
- a non-smoke non-stick pan comprising an inner pan 1 and an outer pan 2, between which a gap 3 is provided between the inner pan 1 and the outer pan 2, in the gap 3 is provided with a heat conductive member 4 for transferring the heat of the outer pot 2 to the inner pot 1, which is in point contact with the inner wall of the inner pot 1, and the inner wall of the outer pot 2, or a small area.
