Detailed Description

The following description of the embodiments of the present invention will be made with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1-8, the present invention provides a cookware with dynamic display of identification. In one embodiment, the cookware is a pot. According to the practical application scene, the kitchen ware can also be a kitchen utensil such as a baking tray.

The inner surface of the kitchenware is coated with at least two ink coatings, wherein the two ink coatings comprise a first ink coating 1011 and a second ink coating 1012; the first ink coating 1011 is positioned below the second ink coating 1012, and the first ink coating 1011 and the second ink coating 1012 are printed with different patterns, wherein the pattern printed by the second ink coating is the identification pattern 1002; the first ink coating 1011 contains a high temperature color change material one, which decreases in color saturation with increasing temperature; the second ink coat 1012 contains a second thermochromic substance, which increases in color saturation with increasing temperature; the identification pattern 1002 is highlighted as the cookware is heated above a first predetermined temperature.

In one embodiment, the first ink layer 1011 contains a high temperature color-changing substance, perylene red, which decreases in color saturation with increasing temperature, so that the user looks that the color of the pattern printed by the layer becomes lighter as the temperature increases. The second ink coating 1012 contains a second high-temperature color-changing substance which is iron oxide; which increases in color saturation with increasing temperature so that the user looks as if the color of the pattern printed by the layer becomes darker as the temperature increases.

Compared with the prior art, the single-channel ink is not obvious in color development, and the user experience is not good; the combination of '1 deepening +1 lightening' is adopted, and the color change is reflected through the contrast of the color saturation, so that the contrast sharpness of the two layers of patterns is increased suddenly, the perception of a user on the color change is also improved rapidly, and more accurate temperature points are captured easily. The user can put the pan at a proper temperature point (for example, 180 ℃ braised frying, 220 ℃ quick frying), the point position is accurate, and the cooking experience is good.

Preferably, the inner surface of the cookware has a top coat 103 on top of the two ink coats, the top coat 103 having a mica component to increase diffuse reflection. In the surface coating, the addition of mica increases the diffuse reflection and covers part of the color change effect. Mica is used for increasing diffuse reflection, so that the color is more glossy; the absence of mica leads to a coarse, dull and matt colour. Therefore, it is necessary to control the content of mica at a lower level. Moreover, the low-reflectivity mica is adopted, which also contributes to the improvement of the effect.

Preferably, the kitchen utensil has a bottom surface for placement and a side surface surrounding the bottom surface, and the two ink coatings are both located on the bottom surface and/or the side surface of the kitchen utensil. In one embodiment, two ink coatings are arranged on the side surface, so that human eyes can have a more comfortable observation effect, and a user can observe the ink more conveniently in the cooking process. In one embodiment, two ink coats are disposed on the bottom surface. Because the temperature difference exists between the bottom surface and the side surface, the bottom surface is the region heated most quickly, and the color is timely and obvious when the bottom surface is arranged. In a pan in use, there is a bottom peripheral ring between the bottom and the side. For a round bottom pan, the bottom and sides are not critical.

Further, the inner surface of the kitchen ware is provided with a pattern area 1001, the two printing inks are coated on the pattern area 1001, and the number of the pattern areas 1001 is one or more. According to actual needs, one or more pattern areas can be arranged on the inner surface of the kitchen ware optionally to display the required effect.

Preferably, a plurality of pattern areas are distributed on the inner surface of the kitchenware at different temperatures at the same time, and the second ink coatings of different pattern areas have different color-changing temperatures. For example, the pattern areas are respectively arranged on the bottom surface and the side surface of the kitchen ware, so that before food materials are placed in a pot, a user can quickly know the heat degree of the pot bottom according to the patterns quickly displayed on the bottom surface, and oil and the food materials can be conveniently added in time; after the food materials are put in, the user can also know the current temperature in the pan according to the patterns displayed on the side surface and adjust the firepower. Through setting up the pattern in a plurality of regions, not only make kitchen utensils and appliances can real-time highlight sign such as trade company logo, the advertising effect is good, still makes the user can obtain omnidirectional temperature feedback in the different stages of culinary art, has promoted user experience and has felt.

In one embodiment, the area of the pattern area 1001 printed by the first ink coating 1011 is larger than the area of the identification pattern 1001; and the logo 1002 is within the area of the pattern printed by the first ink coat 1011. Thus, as the pattern forming the two coats of ink is varied in saturation to create a sharp visual contrast, the logo pattern 1002 is displayed in the pattern area 1001 of the first coat to have a more prominent display effect. Otherwise, the contrast effect is not obvious. The pattern area 1001 may be any shape, such as a square or circular pattern, and the pattern printed by the first ink coating 1011 is a square pattern or a circular pattern.

In one embodiment, as shown in fig. 1-4, the inner surface of the cookware is coated with a primer layer 101, a midcoat layer 102 and a topcoat layer 103 from bottom to top on the substrate 100, and the two ink coats, i.e. the first ink coat 1011 and the second ink coat 1012, are located between the primer layer 101 and the midcoat layer 102 or between the midcoat layer 102 and the topcoat layer 103 on the inner surface of the cookware. Preferably, two ink coats may be located between the middle coat 102 and the top coat 103.

At present, the technological process of the non-stick pan mainly comprises the following steps: prime coat and top coat → intercoat and top coat → sinter. The ink is a pre-prepared dispersion containing a color-changing coating, and the color-changing ink is added into the process to form three processes of a non-stick pan with a color-changing function.

The process a comprises the following steps: prime coat and top coat → one ink and top coat → two ink → intercoat, top coat and sinter. The cookware coating structure obtained by the process a has two structures, which are respectively shown in figures 1 and 2.

And (b) process: bottom coat and top coat → middle coat and top coat → one ink → top coat → two ink → top coat and sinter. The cookware coating structure obtained by the process b has two structures, which are respectively shown in figures 3 and 4.

And a process c: prime and surface coating → intermediate and surface drying → two ink passes → surface coating and sintering.

In one embodiment, the first pass of ink prints a box pattern and the second pass of ink prints a merchant identification logo. Wherein, the color saturation is reduced after the first ink is heated, the color saturation is increased after the second ink is heated, and the contrast between the first ink and the second ink is obvious.

Among the above processes, the process a and the process b/c can be classified into two different types. The process a is to make two layers of printing ink on the base coat; then, the coating is carried out on the surface and the sintering is carried out.

The process b/c is to make ink on the middle coating; and the process b is to coat two ink lines, and the process c is to coat only one ink line, namely the second ink line for displaying the logo.

Wherein the sintering temperature is 380-410 ℃.

In this embodiment, the preferred process b implements the configuration of each structure and shape of the present invention, as shown in fig. 4.

As shown in fig. 5, after the pot 1000 is prepared, at normal temperature, the color of the square frame in the obtained pattern area 1001 is obvious, and the logo identification pattern in the pattern area is invisibly displayed and cannot be seen unless careful. As shown in fig. 6, after heating, the color difference between the background of the box in the pattern area 1001 and the logo mark pattern 1002 increases, the box becomes lighter, and the logo becomes more visible, so that a good contrast highlighting effect is obtained. The Logo pattern 1002 may have any shape. Further, when the cookware is heated to a second preset temperature, the color saturation difference between the identification pattern 1002 and the pattern area 1001 printed by the first ink coating 1011 does not change, and the second preset temperature is higher than the first preset temperature.

In one embodiment, the first predetermined temperature is any value between 130 ℃ and 200 ℃, and the second predetermined temperature is about 240 ℃.

During the heating process of the pot, logo begins to appear but is not obvious at about 130 ℃; logo display is more evident with increasing temperature, with less variation around 200 ℃; by about 240 ℃, logo basically does not change.

In other embodiments, the first ink is printed on the outer ring, the second ink is printed in the outer ring and in the middle, and the outer diameter of the outer ring approaches the inner diameter of the pot bottom. The width of the outer ring is preferably 12-20mm, and the width of the inner ring is preferably 4-10 mm; most preferably, the outer ring has a width of 14.5mm and the inner ring has a width of 6.5 mm. As shown in fig. 7, at normal temperature, the pattern area 1001 at the bottom of the pot 1000 is ring-shaped, which is close to the edge of the bottom of the pot, the color of the ring-shaped area is obvious, and the logo mark pattern therein is invisibly displayed and cannot be seen without care. In this embodiment, logo designations within the pattern area 1001 are also circular. As shown in fig. 8, after heating, the color difference between the ring-shaped background in the pattern region 1001 and the logo mark pattern 1002 increases, the ring-shaped background gradually becomes lighter, and the logo therein gradually appears, thereby obtaining a good contrast effect.
