Description

Cu-containing stainless steel induction heating plate used for induction heating kitchen equipment {INDUCTION TRANSHEAT PLATE COMPOSING STAINLESS STEEL CONTAINED COPPER USING IN INDUCTION RANGE}

The present invention relates to a Cu-containing stainless steel induction heating plate used for an induction heating kitchen container, and relates to an induction heating plate attached to a bottom surface of a kitchen appliance used for an induction heating (IH) type heating device.

The induction heating device is called an induction range, and the heating device is an induction heating device that heats only the kitchen vessel without heating the top of the range through magnetic force using a coil.

Such a heating device is stopped by lifting the kitchen vessel is heated only the portion where the kitchen vessel touches. Therefore, it is easy to clean and fine temperature control is not burned or pressed.

Therefore, in order to maximize the thermal conductivity as much as possible, the kitchen container for an induction heating type electric appliance needs to have a flat bottom and maximize the contact area with the top plate of the electric heater.

 On the other hand, in the material of the kitchen vessel, if you want to simply increase the thermal conductivity, but the entire kitchen vessel is formed of stainless steel, but stainless steel has a heavy self-load, difficult processing.

Therefore, a method of applying a combination of stainless steel having excellent thermal conductivity and aluminum having a light and beautiful color with easy processing has been considered.

Conventional kitchen containers of this coupling method is manufactured in the form of incorporating a flat stainless steel to the bottom of the curved container. And, in order to increase the induction heat transfer efficiency, and to increase the bonding force between the stainless steel plate and the aluminum container, a hole is formed in the plate of the stainless steel, the aluminum plate of the bottom of the kitchen vessel is filled with the hole during press processing, the plate is not curved It is processed to achieve.

However, the conventional kitchen vessel still has a lot of room to improve the induction heat transfer efficiency, in particular, through the improvement of the induction heat transfer efficiency has been a problem of rapid heating of the kitchen vessel and thereby reducing power consumption.

The present invention has been made to achieve the above object, while optimizing the placement of the coupling hole in the stainless steel induction heating plate to improve the induction heat transfer efficiency, while inducing a specific metal component in the stainless steel material to maximize the induction heat transfer efficiency It is for the purpose of providing a heat transfer plate.

In order to achieve the above object, the present invention, the induction heating plate for induction heating type heating apparatus is processed into a stainless steel plate material, a plurality of coupling holes are formed perforated, integrally coupled to the bottom surface of the aluminum alloy material. In the stainless steel, which is a raw material of the induction heating plate, Cu is included.

In addition, the content of Cu is 0.014 ~ 0.074% by mass.

In addition, the ratio of the area of the coupling hole to the area of the induction heating plate is 20 to 30%.

In addition, the arrangement of the coupling holes is a regular arrangement of square and round shapes.

In addition, the induction heating plate is formed in a donut shape concave on one side, the outer edge and the center border is folded toward one of the surfaces of the induction heating plate to form a jaw portion on the outer edge and the center border.

The induction heating type kitchen appliance kitchen vessel combined with the applied induction heating plate of the present invention is high induction heat efficiency, high heat output can be obtained with less power, and it is heated quickly and has the effect of minimizing power consumption.

Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the present invention.

1 is a bottom perspective view of a kitchen vessel in which a stainless steel induction heating plate of the preferred embodiment to which the present invention is applied is integrally attached, FIG. 2 is a plan view of a stainless steel induction heating plate of the preferred embodiment to which the present invention is applied, and FIG. An enlarged cross-sectional view of the line cross section and the chin.

In this embodiment, the material of the induction heating plate 1 is made of stainless steel, and in particular, STS430 stainless steel is used. STS430 has mass% of C: 0.0336 ~ 0.0446%, Si: 0.290 ~ 0.337%, Mn: 0.346 ~ 0.385%, P: 0.0202 ~ 0.0210%, S: 0.0045 ~ 0.0056%, Cr: 15.16 ~ 16.18%, Ni: 0.10 ~ 0.14%, Mo: 0.02 ~ 0.03%, N: 0.0389 ~ 0.0465% of the elements, among which Cu is contained in the range of 0.014 ~ 0.074% by mass.

And, the main body 10 of the kitchen vessel is composed of a conventional aluminum alloy.

As described above, in the present embodiment, the bottom surface of the main body of the kitchen vessel 10 formed of an aluminum alloy, which is easy to process and has a beautiful appearance and is light in weight, is made of stainless steel, which is a metal having corrosion resistance and high surface hardness and high induction heat transfer efficiency. It is configured to combine the induction heating plate (1) formed.

In addition, as shown in Figure 2, the induction heating plate 1 is formed in a regular arrangement of a plurality of rectangular coupling holes (2) and round coupling holes (3), for example, induction heating heater top plate In consideration of functional aspects such as preventing the kitchen vessel from slipping the coupling holes (2, 3) can be formed in various arrangements.

In this embodiment, the arrangement of the coupling holes 2 and 3 is arranged such that the round coupling holes 3 are arranged radially again between the radial rectangular coupling holes 2.

And, as shown in the cross-sectional view of Figure 3, the induction heating plate 1 in the present embodiment, by folding the disc-shaped end at a right angle to form a jaw portion 5, and in the center of the disc center hole ( While forming 4), the end of the center joining hole 4 is also folded at right angles in the same direction as the end of the disc to form a jaw, thereby forming the entire induction plate 1 into a concave donut shape.

The center coupling hole 4 is formed in a concave region lower than the surface of the induction heating plate 1. This is because the convex portion (not shown) for fixing the position of the upper plate of the induction heating type heating apparatus is fitted into the center coupling hole 4, whereby the kitchen vessel body 10 slides or moves on the upper plate of the heating apparatus so that the heat transfer is stopped. This is to prevent the case.

As described above, the induction heating plate 1 is formed by forming a jaw around the center coupling hole 4 forming a step between the bottom surface of the main body 10 of the center coupling hole 4 and the induction heating plate 1. By maintaining the flatness of the rest of the, it is possible to maximize the induction heating efficiency while acquiring the anti-slip function of the main body 10 as described above.

The kitchen vessel body 10 and the induction heating plate 1 are coupled by press working, and the aluminum alloy of the body 10, which is a relatively soft material, is filled into the coupling holes 2 and 3, so that the body ( 10) and the coupling force of the induction heating plate (1) is maximized.

However, since stainless steel is more efficient in terms of induction heat transfer efficiency than aluminum alloy, it is preferable that the area of stainless steel at the bottom of the main body 10 is larger than that of the aluminum alloy in order to increase the induction heat transfer efficiency of the entire kitchen vessel. .

Therefore, in this embodiment, the ratio of the area of the coupling holes 2 and 3 to the total area of the induction heating plate 1 is limited to 20 to 30%.

The reason for limiting the area ratio as described above is that if the ratio is less than 20%, the area of the coupling holes 2 and 3 is too small, and the coupling force between the main body 10 and the induction plate 1 decreases. On the contrary, when it exceeds 30%, the area of the aluminum alloy is widened and the induction heat transfer efficiency is lowered.

On the other hand, in the present embodiment, as shown in Figure 3, the edge of the induction heating plate (1) was formed so that the jaw portion 5 protruding from the kitchen vessel body 10, which is of the kitchen vessel body 10 While the bottom circumferential edge is rounded, the induction heating plate 1 maintains a flat state over the entire surface to maximize the contact area with the top plate of the induction heating heater, and as a result, the main body of the kitchen vessel 10 Since the flat edge of the induction heating plate 1 protrudes from the rounded edge around the bottom of the bottom surface, the jaw portion 5 has an angled shape.

1 is a bottom perspective view of a kitchen vessel to which a stainless steel induction heating plate of the preferred embodiment to which the present invention is applied is integrally attached.

2 is a plan view of a stainless steel induction heating plate of a preferred embodiment to which the present invention is applied.

3 is a partially enlarged cross-sectional view taken along the line A-A of FIG.
