Description

Technical area

The present invention belongs to the technical field of kitchen utensils and relates in particular to a nonstick skillet structure.

Background technique

In everyday life, the conventional structure of a pan consists of a single-layer body that is coated with a nonstick coating and is mainly made of iron or stainless steel. When using such a stove body, the food is often fixed on the body of the pan, which causes a problem of carbonization, as well as the unequal heating of food, insufficient resistance to the use of this body and other problems because of this structure too simple.

The Chinese Utility Model whose publication number is CN 201814359U and the date of publication is May 4, 2011, describes a dual-layer composite pan whose body is formed by an inner container and an outer container, which are grouped together by extrusion and pressing. The inner container is manufactured independently by extrusion and drawing, with a stainless steel coating and at the same time the outer container with an aluminum alloy coating or vice versa.

However, the composite stove described by this Utility Model has the problem that the non-stick effect is poor and the resistance to use is low.

detailed description

The following description is only that of a preferred embodiment of the invention, provided for information but not limitation, and the scope of the invention is not limited by it.

As shown in FIGS. 1, 2, 3 and 4, a nonstick skillet structure comprises an outer container 1 and an inner container 2 which are connected to each other, the outer container 1 comprising an outer bottom 101, a outer connecting portion 102 being disposed on said bottom 101, and a container wall 103 being connected to the connecting portion 102. The inner container 2 comprises an inner bottom 201 provided to be placed on the outer bottom 101 and a connecting portion. 202 is positioned on said inner bottom 201.

In the present example, the inner bottom bonding portion 202, the outer bottom bonding portion 102 and the container wall 103, all of these components having been previously described, are integrally connected, to improve the resistance to the use of the whole nonstick pan and its durability. In addition, the connecting portion 102 serves as a bond transition between the outer bottom 101 and the wall 103, which improves the overall appearance effect.

Said inner bottom 201 is provided with a concave-convex surface 3 to achieve a non-stick effect physically, and this surface 3 comprises coatings 4 to obtain a release effect chemically.

In the present embodiment, the concave-convex surface 3 serves as an effective part for the nonstick physical mode of the nonstick skillet, while the liner 4 is made of an anti-stick chemical material to provide the anti-adhesive effect. Compared to the coating that is applied directly to the pan body, the coating according to this example has the advantages of a better non-stick effect and greater scraping resistance.

The concave-convex surface 3 comprises a concave groove 301 for receiving the coating 4 and retaining the liquid portion of the food, and a convex portion of the inner bottom 302 for receiving the coating 4 and supporting the food.

In the present example, said concave groove 3 has two functions: i) to receive the coating, the layer being inside the groove and being less likely to be scraped during the sliding of a spatula, in order to increase the service life of the coating; ii) at the time of use, the liquid portion of the food is housed in the groove, and the food is supported in a form similar to that of a film of water, to reduce the area of direct contact between food and the pan, the theory being that only the convex portion 302 is connected to food, to ensure the nonstick effect.

The inner bottom connection portion 202 comprises two connection blocks, of which a first link block 20201 is disposed on said inner bottom 201 and is connected to said outer bottom connecting portion 102, while the second block 20202 is placed in the first block 20201 and is connected to said outer container wall 103.

In the present example, the outer bottom connecting portion 102 is located in a relatively low position while the outer container wall 103 is located in a relatively raised position, and the two portions are connected to the inner bottom connection 202 to to ensure the strength of the combined connection between the entire inner container 2, the internal bottom connection 202 and the entire outer container 1, to improve the durability of the body of the pan.

In the inner bottom connection 202, the side surface remote from the outer bottom bond 102 is a curved surface 20203, to effect a smooth transition during slip of a spatula.

In this exemplary embodiment, said curved surface 20203 has its upper end connected to the container wall 103 and its lower end connected to the inner bottom 201, serving as a sliding transition up and down for a spatula, providing a transition smoothly and reducing the impact of the spatula on the inner bottom 201 and the outer container wall 103.

The outer bottom connection 102 has an inner side surface 104 and an outer side surface 105, both of rounded shape, connected to the inner connecting portion 202. On the one hand, compared with the case where the container wall 103 is disposed directly on the outer bottom 101, in the present embodiment, the outer bottom connecting portion 102 is designed such that the angle between the wall 103 and the link 102 is greater than the angle between the wall 103 and the outer bottom 101, thereby avoiding the process of folding the stainless steel as a whole at a wide angle, which is used as the entire outer container 1; the transition angle becomes smaller, which ensures the resistance to use and prevents the reduction in service life caused by bending at a wide angle. On the other hand, the outer bottom connecting portion 102 is a three-dimensional annular shape formed as follows: the inner and outer parallel sides form a rectangle and the second rotates about the axis; in addition, the straight lines on the inner and outer sides of the section make the appearance of the entire stove more beautiful.

In the outer container 1, the outer side surface has an outer protective layer 5. In the present embodiment, the outer protective layer 5 comprises a polishing, sanding, protective coating and enamel layer in order to ensure resistance to use and service life of the outer side surface of the outer container 1.

In the container wall 103, the inner side surface comprises an inner protective layer 6. In the present example, the inner protective layer 6 comprises the polishing, sanding and protective layers, in order to improve the effect. of wear and service life of the inner side surface of said wall 103.

There is an edge 107 in the container wall 103, and the outer protective layer 5 extends to that edge 107.

The inner protective layer 6 extends to the inner bottom connection 202. In the present example, when the inner protective layer 6 is the protective coating, it must be connected to the coating 4; and when the inner protective layer 6 is the polishing and sanding layers, the operations of the polishing and sanding process also extend down to the coating 4.

Although the embodiment of the invention has been described in detail with reference to the drawings, the invention is not limited to the embodiments mentioned above, and it is understood that various modifications can be made without departing of the spirit of the invention in the context of the knowledge available to those practicing in this technical field. The amendments, as long as they fall within the scope defined by the following claims, fall within the scope of the protection conferred.
