Description

Technical Field

[0001] The invention relates to a cooking utensil, and in particular to an improvement of a pot body of the cooking utensil. Background Art

[0002] Due to the superiority, efficiency and safety of IH heating technology, many electric pressure cookers on the market currently use IH heating. IH heating electric pressure cookers generally include a pot body and a pot lid. The pot body includes an outer pot and an inner pot arranged in the outer pot. Since the heating principle of IH is that the inner pot cuts the magnetic flux lines to generate heat, the inner pot should be made of magnetic conductive materials. However, the inner pot made of magnetic conductive materials will result in excessively high production costs. Currently, it is generally achieved by coating the surface of the ceramic inner pot with a magnetic conductive layer, but the cost of ceramic materials is still high, resulting in a high cost for the entire electric pressure cooker. Summary of the invention

[0003] The main purpose of the present invention is to provide a cooking utensil to solve the problem of high cost of the cooking utensil in the prior art.

[0004] In order to achieve the above-mentioned purpose, the present invention provides a cooking utensil, including: a pot body for holding food to be cooked, the pot body including a pot body main body and a magnetic conductive layer that can be electromagnetically heated, the pot body main body is made of aluminum alloy material, and the magnetic conductive layer is coated on the pot body main body and formed on the pot body main body through low-temperature sintering.

[0005] By applying the technical solution of the present invention, the pot body of the cooking utensil includes a pot body and a magnetic conductive layer that can be electromagnetically heated, and the pot body is made of an aluminum alloy material, so the production cost will be greatly reduced. However, since the pot body made of an aluminum alloy material cannot be magnetic, it is necessary to provide a magnetic conductive layer on the outside of the pot body. In the present invention, the magnetic conductive layer is coated on the pot body and then formed on the pot body by low-temperature sintering. The magnetic conductive layer formed on the pot body by low-temperature sintering has the advantages of high strength and wear resistance, so there is no need to cover the outer layer of the magnetic conductive layer with a protective layer, thereby simplifying the production steps, improving production efficiency, reducing production costs, and solving the problem of high cost of cooking utensils in the prior art.

[0006] Furthermore, the temperature of the low temperature sintering is between 200°C and 600°C.

[0007] Furthermore, components of the magnetic conductive layer include silver and iron.

[0008] Furthermore, the magnetic conductive layer is coated on the pot body by water transfer printing.

[0009] Furthermore, the magnetic conductive layer is coated on the outer surface of the pot body.

[0010] Furthermore, the thickness of the magnetic conductive layer is less than 0.15 mm.

[0011] Furthermore, the pot body includes a bottom wall and a side wall, the side wall is an arc-shaped side wall, and the magnetic conductive layer is covered on the bottom wall and the arc-shaped side wall.

[0012] Furthermore, the arc-shaped side wall includes an upper arc segment and a lower arc segment connected to each other, and the magnetic conductive layer covers the lower arc segment.

[0026] like Figure 1 and Figure 2 As shown, the cooking utensil of the first embodiment includes a pot body 10, which is used to hold food to be cooked. The pot body 10 includes a pot body 11 and a magnetic conductive layer 12 that can be electromagnetically heated. The pot body 11 is made of aluminum alloy material, and the magnetic conductive layer 12 is covered on the pot body 11 and then formed on the pot body 11 through low-temperature sintering.

[0027] By applying the technical solution of the first embodiment, the pot body 10 of the cooking utensil includes a pot body 11 and a magnetic conductive layer 12 that can be electromagnetically heated. The pot body 11 is made of an aluminum alloy material, so the production cost will be greatly reduced. However, since the pot body 10 made of an aluminum alloy material cannot be magnetic, it is necessary to set a magnetic conductive layer 12 on the outside of the pot body 11. In the first embodiment, the magnetic conductive layer 12 is formed on the pot body 11 by low-temperature sintering after being coated on the pot body 11. The magnetic conductive layer 12 formed on the pot body 11 by low-temperature sintering has the advantages of high strength and wear resistance, so there is no need to cover the outer layer of the magnetic conductive layer 12 with a protective layer, thereby simplifying the production steps, improving production efficiency, reducing production costs, and solving the problem of high production costs of cooking utensils in the prior art.

[0028] In the first embodiment, the low temperature sintering temperature is between 200° C. and 600° C. Sintering within the above temperature range enables the magnetic conductive layer 12 to be better coated on the pot body 11 and optimizes the magnetic conductivity and wear resistance of the magnetic conductive film.

[0029] In the first embodiment, the components of the magnetic conductive layer 12 include silver and iron. In the above structure, silver acts as an adhesive and iron acts as a magnetic conductor. Of course, those skilled in the art should know that the components of the magnetic conductive layer 12 may also include materials with good magnetic conductivity such as cobalt or nickel. Specifically, the magnetic field in which the pot body 10 is located is constantly changing, and the pot body with the magnetic conductive layer 12 can cut the magnetic flux lines to generate heat, and finally achieve the purpose of heating the food in the pot body 10.

[0030] In the first embodiment, the magnetic conductive layer 12 is coated on the pot body 11 by water transfer printing. Since the water transfer printing technology has the advantage of not being restricted by complex curved surfaces, the magnetic conductive layer 12 can be well coated on the complex curved surface by water transfer printing. Preferably, in this embodiment, the pot body 10 is a spherical kettle, and the magnetic conductive layer 12 can be well coated on the curved outer surface by water transfer printing technology. In addition, the water transfer printing technology is a very environmentally friendly technology, and the residues or wastewater after the process will not pollute the environment.

[0031] like Figure 1 and Figure 2 As shown, in the first embodiment, the magnetic conductive layer 12 is coated on the outer surface of the pot body 11. The above structure is simple and convenient to process. Of course, those skilled in the art should know that the magnetic conductive layer 12 can also be coated on the inner surface of the pot body 11.

[0032] like Figure 1 and Figure 2 As shown, in the first embodiment, the thickness of the magnetic conductive layer 12 is less than 0.15 mm. The above structure can ensure both magnetic conductivity and wear resistance by ensuring that the volume of the pot body 10 is as small as possible, thereby improving the appearance of the product.

[0033] like Figure 1 and Figure 2 As shown, in the first embodiment, the pot body 11 includes a bottom wall 111 and a side wall 112 , the side wall 112 is an arc-shaped side wall, and the magnetic conductive layer 12 covers the bottom wall 111 and the arc-shaped side wall.

[0034] like Figure 1 and Figure 2 As shown, in the first embodiment, the arc-shaped side wall includes an upper arc segment 1121 and a lower arc segment 1122 connected to each other. Since the magnetic flux lines pass through the lower arc segment 1122 more and pass through the upper arc segment 1121 less, in this embodiment, the magnetic conductive layer 12 covers the lower arc segment 1122. The above structure can further reduce the production cost and solve the problem of high production cost of cooking utensils in the prior art.

[0035] like Figure 1 and Figure 2 As shown, in the first embodiment, the cooking appliance further includes: an IH heating device, which is arranged below the pot body 10 to heat the pot body 10 .

The inner pot is the pot body 10 mentioned above.

The pot body 11 is made of aluminum alloy material, and the magnetic conductive layer 12 is covered on the pot body 11 and then formed on the pot body 11 through low-temperature sintering.

[0039] By applying the technical solution of the second embodiment, the pot body 10 of the cooking utensil includes a pot body 11 and a magnetic conductive layer 12 that can be electromagnetically heated. The pot body 11 is made of an aluminum alloy material, so the production cost will be greatly reduced. However, since the pot body 10 made of an aluminum alloy material cannot be magnetic, it is necessary to set a magnetic conductive layer 12 on the outside of the pot body 11. In this embodiment, the magnetic conductive layer 12 is formed on the pot body 11 by low-temperature sintering after being coated on the pot body 11.

[0040] In the second embodiment, the low temperature sintering temperature is between 200° C. and 600° C.

Preferably, in this embodiment, the pot body 10 is a spherical kettle, and the magnetic conductive layer 12 can be well coated on the curved outer surface by water transfer printing technology. In addition, water transfer printing technology is a very environmentally friendly technology, and the residues or wastewater after the process will not pollute the environment.

The above structure can ensure both magnetic conductivity and wear resistance by ensuring that the volume of the pot body 10 is as small as possible, thereby improving the appearance of the product.

[0045] like Figure 3 and Figure 4 As shown, in the second embodiment, the pot body 11 includes a bottom wall 111 and a side wall 112 , the side wall 112 is an arc-shaped side wall, and the magnetic conductive layer 12 covers the bottom wall 111 and the arc-shaped side wall.

[0046] like Figure 3 and Figure 4 As shown, in the second embodiment, the arc-shaped side wall includes an upper arc segment 1121 and a lower arc segment 1122 connected to each other. Since the magnetic flux lines pass through the lower arc segment 1122 more and pass through the upper arc segment 1121 less, in this embodiment, the magnetic conductive layer 12 covers the lower arc segment 1122. The above structure can further reduce the production cost and solve the problem of high production cost of cooking utensils in the prior art.

The inner pot is the pot body 10 mentioned above.

[0049] The cooking device of the third embodiment (not shown) is different from the first embodiment in the specific structure of the pot body. Specifically, in the third embodiment, the pot body includes an outer pot and a heat preservation cover arranged in the outer pot.
