Description

Technical Field

[0001] This utility model relates to the technical field of kitchen cooking utensils, and in particular to a flat-bottomed pan structure with electromagnetic induction. Background Technology

[0002] Induction heating (IH) stoves and induction cookers are much safer than gas stoves and have gradually become essential appliances in many households in recent years. However, because IH stoves and induction cookers use a special heating principle, there are some restrictions on the types of cookware that can be used. For example, only cookware made of materials such as iron or stainless steel that are molded in one piece can be heated by electromagnetic induction in IH stoves and induction cookers.

[0003] Furthermore, cookware used with IH stoves and induction cookers should ideally have a flat bottom, without any unevenness, otherwise it will affect the electromagnetic induction heating effect. If the bottom of the pot is uneven, the distance between the heating coil and the bottom of the pot will be inconsistent, and the heating efficiency will be reduced. Therefore, flat-bottomed pots are more suitable for IH stoves and induction cookers.

[0004] However, existing frying pans on the market with electromagnetic induction heating often experience a bulge in the center of the bottom when heated to over 100°C, preventing them from fully adhering to the cooktop of stoves and induction cooktops. This affects the overall operability of the cookware during cooking. Therefore, based on practical application and research of the aforementioned frying pans with electromagnetic induction heating, it is known that their structure still has shortcomings that need improvement. Utility Model Content

[0005] In view of the problems existing in the above-mentioned electromagnetic induction frying pan structure, the main purpose of this utility model is to provide an electromagnetic induction frying pan structure that ensures the flatness of the pan bottom during heating; the secondary purpose of this utility model is to provide an electromagnetic induction frying pan structure that ensures the concentration of heated cooking oil in the pan.

[0006] To achieve the above objectives, the present invention employs the following technical means: The present invention provides a flat-bottomed pan structure with electromagnetic induction, comprising: a pan body, which is integrally bent from a material with magnetic properties to have a bottom and a side rim, wherein the bottom of the pan is provided with an annular magnetic groove corresponding to the shape of the bottom and protruding from the outer side of the bottom; and a grip portion, which is attached to the outside of the side rim of the pan body.

[0007] The depth of the annular magnetic groove at the bottom of the pot is set between 0.5mm and 2mm.

[0008] The material with magnetic properties is configured as a single-layer iron plate, a single-layer hot-rolled plate, a single-layer stainless steel plate, or a multi-layer composite material containing such materials.

[0009] The pot body is designed to be circular, rectangular, or at least hexagonal or more polygonal.

[0010] The grip portion is a long single handle, and a hanging ring is provided at the end of the long single handle.

[0011] The gripping part is configured as two opposing handles.

[0012] The bottom of the pot within the annular magnetic groove is designed with an outwardly curved bottom, and when the bottom of the pot is heated, the maximum expansion size of the outwardly curved bottom will not exceed the size of the outwardly protruding annular magnetic groove.

[0013] By employing the aforementioned technical means, this utility model can achieve the following effects:

[0014] 1. The present invention provides an annular magnetic groove at the bottom of the pot to enhance the structural strength of the bottom of the pot; in other words, when the pot is heated by electromagnetic induction from an IH furnace or an induction cooker, the bottom of the pot is not easily deformed by heat, so that the annular magnetic groove can still be completely flat against the cooktop without reducing the heating efficiency of the IH furnace or induction cooker on the bottom of the pot.

[0015] 2. The present invention provides an outer curved bottom in the pot bottom within the range of the annular magnetic groove, so as to concentrate the heated cooking oil in the pot and enable the food to be fried, stir-fried and cooked smoothly. Attached Figure Description

Detailed Implementation

[0021] This utility model provides a flat-bottomed pan structure with electromagnetic induction, such as... Figures 1 to 3 As shown, this invention provides a utensil primarily for use as cooking ingredients, and addresses the problem that existing electromagnetic induction frying pans deform under heat and cannot be stably placed on IH stoves and induction cookers. The electromagnetic induction frying pan structure A of this invention includes: a pan body 1 and a gripping part 2, etc. The above components are described in detail below with reference to the accompanying drawings.

[0022] The pot body 1 is integrally bent from a magnetically conductive material to form a bottom 11 and a side rim 12. The magnetically conductive material is a single-layer iron plate, a single-layer hot-rolled plate, a single-layer stainless steel plate, or a multi-layer composite material containing these materials. The bottom 11 has an annular magnetically conductive groove 111 that corresponds to the shape of the bottom 11 and protrudes from its outer surface. The depth of the annular magnetically conductive groove 111 is between 0.5 mm and 2 mm. Furthermore, the bottom of the pot within the annular magnetically conductive groove 111 has an outwardly curved bottom 112. The pot body 1 can be circular, rectangular, or at least hexagonal or higher polygonal, meaning that the aforementioned at least hexagonal or higher polygonal shape includes hexagons, heptagons, octagons, etc. Specifically, if the pot body 1 is polygonal, the bottom 11 and the side rim 12 also have the corresponding polygonal shape.

[0023] The grip 2 is attached to the outer side of the side rim 12 of the pot body 1. The grip 2 is a long single handle 21, with a hanging ring 22 at the end of the handle 21 to facilitate operation on an IH stove or induction cooker. Alternatively, the grip 2 can be configured as two opposing handles to facilitate lifting the pot body 1.

[0024] Therefore, this utility model provides a preferred solution for a flat-bottomed pan structure with electromagnetic induction, which allows the bottom of the pan to adhere flat to the surface 3 of an IH stove and an induction cooker during the heating process. Please refer to the following reference. Figure 4 As shown, the electromagnetic induction frying pan structure A of this invention works by placing the pan body 1 on the cooktop 3 of an IH stove or induction cooker. The annular magnetically conductive groove 111 on the bottom 11 of the pan body 1 will flatten against the cooktop 3. When the IH stove or induction cooker is turned on to electromagnetically heat the bottom of the frying pan, the magnetically conductive groove 111 strengthens the structure of the bottom 11. Even when the bottom 11 is heated to above 100°C and below 150°C, the annular magnetically conductive groove 111 is not easily deformed and can remain flattened against the cooktop 3, so as not to affect the operability of the pan body 1 in cooking food.

[0025] In addition, the present invention provides an outer curved bottom 112 at the bottom of the pot within the range of the annular magnetic groove 111, and when the bottom of the pot 11 is heated, the maximum expansion size of the outer curved bottom 112 will not exceed the size of the annular magnetic groove 111.

[0026] Therefore, when cooking food, the pot body 1 of this utility model is first placed on the surface 3 of an IH stove or an induction cooker for heating, and then an appropriate amount of cooking oil 4 is poured in and heated to a suitable temperature before the food is poured into the pot. Because the outer curved bottom 112 concentrates the heated cooking oil 4 in the pot, it is beneficial for frying and cooking food.

[0027] It should be noted that the above description is the technical principle used in the specific embodiments of this utility model. If any changes are made in accordance with the concept of this utility model, and the resulting functions and effects do not exceed the spirit covered by this specification and drawings, they should be included within the protection scope of this utility model.
