Description

Technical Field

[0001] The utility model relates to the technical field of cookware, in particular to a cookware with an oil collecting function at the bottom. Background Art

[0002] Most existing household induction cookers, microwave ovens, and ceramic hobs feature flat cooktops. The bottoms of the pots used are slightly raised to prevent them from sitting flat or spinning on the cooktop. Furthermore, a magnetic sheet is typically placed on the outside of the pot to transmit energy to the pot by responding to the high-frequency magnetic field of the induction cooker, thereby heating the pot.

[0003] Traditional magnetic conductive sheets are integrally laminated to the outer bottom of the aluminum substrate. Due to the different thermal expansion coefficients of the magnetic conductive sheet and the aluminum substrate, the bottom of the pot will bulge inward to varying degrees during heating. As the temperature rises, the bulge becomes larger. During cooking, the cooking oil poured into the pot will flow to the sides of the bottom of the pot, causing the cooking oil to be lost in the middle of the bottom of the pot, affecting the cooking effect of the food. In addition, the different expansion coefficients of the two make it easy for local cracks and other defects to occur between the film layers after long-term use.

[0004] In view of this, the utility model proposes a pot with an oil-collecting function at the bottom. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] Example 1

[0036] According to the attached Figure 1-5 As shown, the embodiment of the present invention provides a pot with a bottom oil collecting function, comprising:

[0037] Cookware body 100, handle assembly 200, first connecting assembly 300 and second connecting assembly 400;

[0038] The cookware body 100 includes a pot base 101, an annular boss 102, a curved surface 103, a non-stick coating 104, a magnetic coating 105, an anti-rust coating 106 and a protective outer layer 107;

[0039] An annular boss 102 is provided on the lower surface of the cookware body 100, and a curved surface 103 is provided on the upper surface of the cookware blank 101. During the cookware manufacturing process, a large-tonnage press is used to form the aluminum alloy sheet into the shape of the cookware blank 101. An annular boss 102 is protruding outward at the outer peripheral edge of the outer bottom of the cookware blank 101. A curved surface 103 protruding outward is formed in the central area of ​​the bottom of the cookware blank 101. The center point of the outermost surface of the curved surface 103 is 1.0 to 1.5 mm different in height H from the outer peripheral edge of the annular boss 102.

[0040] Moreover, the obtained pot blank 101 is subjected to degreasing and internal sandblasting operations. The degreasing operation first uses sodium hydroxide solution to remove grease and oxides on the surface of the pot blank 101, and then rinses it with water; then it is neutralized with dilute nitric acid at room temperature, and finally rinsed with water and blown dry to obtain a clean pot blank 101; the internal sandblasting operation uses a sandblasting machine to evenly spray brown corundum sand onto the inner surface of the pot blank 101 at an air pressure of 0.6MPa, so that the inner surface roughness of the pot blank 101 reaches Ra3.6±4, so as to meet the roughness required for internal coating.

[0041] The non-stick coating 104 is sprayed on the surface of the arc surface 103 on the upper surface of the pot blank 101 by a spraying device, and the material of the non-stick coating 104 is polytetrafluoroethylene coating, and the thickness of the non-stick coating 104 is 200um±5um.

[0043] The cold spraying operation specifically includes the following steps: on the cold gas spraying equipment, nitrogen inert compressed gas with a temperature of 850°C is used as the accelerating medium to accelerate the magnetic powder metal particles (magnetic powder with an average particle size of 25um) to a critical speed, driving the metal particles to collide with the outer bottom surface of the pot blank 101 at a supersonic speed of 920m / s in the solid state, causing the particles to undergo strong plastic deformation and deposition to form a magnetic coating 105.

[0044] The anti-rust coating 106 is sprayed on the outer surface of the magnetic conductive coating 105 by spraying equipment, and the material of the anti-rust coating 106 is metal aluminum, and the thickness of the anti-rust coating 106 is 10um±1um.

[0045] The arc spraying operation specifically includes the following steps: using the arc generated between two continuously fed aluminum wires (diameter ∮2mm) as a heat source through the arc spraying equipment to melt the aluminum wire (flame temperature is about 3000℃), using 0.7MPa compressed air to atomize the molten metal aluminum wire, and accelerating the atomized metal aluminum droplets, spraying them toward the outer bottom of the pot blank 101 at a speed of 160m / s to form a layer of aluminum anti-rust coating 106.

[0046] The protective outer layer 107 is sprayed on the outer surface of the anti-rust coating 106 by an external spraying device.

[0047] In this embodiment, by forming the annular boss 102 and the arc surface 103 from the pot blank 101, and after pretreatment and internal spraying operations, the bottom of the pot is ensured to have a good oil-gathering function, thereby improving the cooking effect of the pot; further, through cold spraying and arc spraying operations, combined with the effect of interface materials with different atomic layers, a pot with long-term and efficient electromagnetic heating and heat conduction under high temperature conditions is obtained, thereby further ensuring the long-term service life of the pot and good cooking effect.
