Referring to Fig. 1, the cooking appliance 10 of the utility model embodiment includes liner 12 and photochromic layer 14.12 shape of liner At chamber 121.Photochromic layer 14 is arranged in 12 inner surface of liner.Photochromic layer 14 is made of thermo colour, the temperature in liner 12 The color change of thermo colour, color change are reversible when degree is more than the discoloring temperature of thermo colour.

The cooking appliance 10 of the utility model embodiment, photochromic layer 14 remind user's cooking appliance by color change Temperature range in 10 liner 12, makes user understand the temperature in liner 12 in time, avoids by liner 12 or liner 12 Article scald.

Specifically, when the temperature in liner 12 reaches discoloring temperature, the color of photochromic layer 14 changes, and clearly accuses Know that the temperature in user's liner 12 is excessively high, unavailable hand directly contacts；When temperature is reduced to set temperature or less, photochromic layer 14 Color before recovery informs the article that user can directly be taken in liner 12 with hand, informs use in a very intuitive way Temperature regime in indoor gallbladder 12, so as to avoid user's blindness Contact Temperature excessively high liner 12 and liner 12 in article And it causes to scald.

Specifically, the inner surface of liner 12 can be completely covered in photochromic layer 14, can also only covering part liner 12 it is interior Surface.Photochromic layer 14 can be set in any position of 12 inner surface of liner.

The color change of photochromic layer 14 is reversible it is to be understood that becoming after the temperature in liner 12 is more than discoloring temperature The color change of chromatograph 14, after the temperature in liner 12 is down to discoloring temperature or less, the color of photochromic layer 14 can restore again to Color originally.For example, the color of photochromic layer 14 is green when the temperature in liner 12 is less than or equal to discoloring temperature, When interior temperature in liner 12 raises to above discoloring temperature, the color of photochromic layer 14 becomes yellow.Temperature in liner 12 When degree is reduced to less than or equal to discoloring temperature, the color of photochromic layer 14 becomes green again.Certainly, the color of photochromic layer 14 can be with It is any other color, such as the color change of photochromic layer 14 can also be orange flavescence color, green flavescence color, purple change indigo plant Color, purple redden color, red flavescence color, blue flavescence color, and aubergine shoals blue, and hyacinthine shoals red, and coffee color reddens Color etc., this is not restricted.The color change of photochromic layer 14 is related with the material composition of photochromic layer 14.

In some embodiments, thermo colour includes inorganic reversible heat-sensible ink, organic reversible heat-sensible ink and liquid crystal Any one in reversible heat-sensible ink.

In this way, photochromic layer 14 changes colour fastly, good reversibility allows user to understand the temperature in liner 12 in real time.

Specifically, inorganic reversible heat-sensible ink is when temperature reaches discoloring temperature, because crystal form changes, the gain and loss crystallization water Or the variation of ligand geometric configuration, so that color changes.Such as red CuHgI4 tetragonal crystal system is more than to become in temperature When color temperature, become the Cu2HgI4 cubic system of black, when temperature is less than or equal to discoloring temperature, and is changed into red The variation of color has occurred in CuHgI4 tetragonal crystal system because of the change of crystal form；Red CoCl26H2O is being more than color temperature Dehydration becomes sapphire CoCl2 after degree, when temperature is less than or equal to discoloring temperature, sapphire CoCl2 and surrounding air In water molecules be changed into red CoCl26H2O again, be due to dehydration caused by color change；[(C2H5) 2NH2] color of 2CuCl4 when temperature is more than discoloring temperature from green to yellow, when temperature is less than or equal to discoloring temperature When, and green is become from yellow, this is mainly due to caused by the variation of structure or ligancy.

Organic reversible heat-sensible ink can be divided into 2 classes by component: one kind is that component or knot occurs after being heated by a kind of compound Structure changes and causes to change colour, and is one-component off-color material, can be directly as thermosensitive chromotropic paint；It is another kind of for it is some heated when In itself and non-discolouring compound occurs chemical reaction and generates heat-sensitive variable colour after it is mixed with other suitable compounds Phenomenon, referred to as multicomponent compound camouflage paint.The Discoloration mechanism of organic reversible heat-sensible ink are as follows:

1) electronics transfer (gain and loss) mechanism.System is mainly by 3 kinds of colour former, color developing agent and solvent at being grouped as.Colour former It is the electron donor in off-color material, provides electronics to electron acceptor, be heat-sensitive variable colour color base, determines the face of compounding objects system Color, itself cannot directly generate heat-sensitive variable colour phenomenon.Common colour former has crystal violet lactone, peacock green lactone, methyl red Deng.Color developing agent is the electron acceptor in off-color material, is the organic compound for causing heat-sensitive variable colour, be can make material change colour and The determinant of the color change depth, it receives the electronics of colour former offer and generates color change reactions.Common color developing agent Have: phenolic hydroxyl-compounds and its derivative, such as bisphenol-A, laurel carboxylic ester, 8-hydroxyquinoline, benzyl p-hydroxybenzoate, 4- hydroxyl Butylcoumariii, alpha-Naphthol, betanaphthol etc.；Carboxyl compound and its derivative, such as stearic acid, caproic acid, terephthalic acid (TPA), octanoic acid Deng.Solvent decides the discoloring temperature of thermo-sensitive material, generally changes heat-sensitive variable colour temperature by changing solvent for use.Commonly Solvent is alcohols solvent, such as n-dodecanol, tetradecanol, positive hexadecanol, positive octadecyl alcolol, alcohols solvent have fusing point it is lower, Cheap, steady performance.In contrast, in above 4 kinds of alcohols solvents, positive hexadecanol best performance.

2) pH value change mechanism.The colour former of this system is mainly acid-base indicator, such as phenolphthalein, phenol red.Color developing agent is Make the meltbility compound of the changed carboxylic acids of pH value and amine.When compound is melted or is solidified with temperature change, Due to the soda acid variation of medium or by thermally-induced molecule structure change, so as to cause the reversible change of color.

3) molecule structure change mechanism.When the temperature is changed, system becomes open loop and molecular structure isomery (along anti-by closed loop Isomery, tautomerism, conformational isomerism), cause color to change.Contain the spiral shell of multiple heterocycles and aromatic ring structure in system molecule Cycle compound, such as spiro-pyrans class, spiral shell piperazine analog derivative, fulgides, heterocyclic diarylethene class, indoline oxazolidine class are derivative Object azo, Schiff bases and chromone compounds etc..These compounds properties are stablized, and heat resistance is good, and discoloration is obvious, discoloration Temperature is lower.

Liquid crystal can be divided into 3 class of smectic liquid crystal, nematic liquid crystal and cholesteric liquid crystal.Liquid crystal reversible heat-sensible ink is mainly cholesterine And its derivative, therefore, heat-sensitive variable colour liquid crystal typically refers to cholesteric liquid crystal, it, which relies primarily on temperature, makes its discoloration, and molecule is in Flat, arrangement is layered, and molecule is parallel to each other in layer, and molecular long axis is parallel to level.Multilayer molecular is gradually reversed into helix, And it is arranged in helicoidal structure along the normal direction of layer, periodic interlamellar spacing is known as screw pitch, and screw pitch plays diffraction grating Effect.Helical structure can also selectively reflected light polarization component, provide rainbow images.As temperature increases, screw pitch is gradually Become smaller, scatter optical wavelength to short wave mobile, color accordingly becomes purple from red, and when the temperature decreases, color becomes from purple again For red.

Hot " Word.In colourless or homochromy with liner 12 when temperature of the photochromic layer 14 in liner 12 is less than or equal to discoloring temperature, user at this time The prompting text that can't see " Caution! Hot ", not in the color with liner 12 when the temperature in liner 12 is more than discoloring temperature Same pre-set color, then shows the prompting text of " Caution! Hot " at this time.Certainly, in other embodiments, photochromic layer 14 Other texts can also be formed.

Photochromic layer 14 can also form prompting pattern, for example, photochromic layer 14 forms the prompting pattern of high temperature warning mark etc.. In colourless or homochromy with liner 12 when temperature of the photochromic layer 14 in liner 12 is less than or equal to discoloring temperature, user is seen not at this time To the prompting pattern of high temperature warning mark, when the temperature in liner 12 is more than discoloring temperature in different from the color of liner 12 Pre-set color, then show the prompting pattern of high temperature warning mark at this time.Certainly, in other embodiments, photochromic layer 14 Other can also be formed and remind pattern.

Photochromic layer 14, which can also be formed, reminds text and prompting pattern.For example, photochromic layer 14 forms mentioning for " Caution! Hot " The prompting pattern for the text and high temperature warning mark of waking up.It is in when temperature of the photochromic layer 14 in liner 12 is less than or equal to discoloring temperature Colourless or homochromy with liner 12, user can't see the prompting figure of the prompting text and high temperature warning mark of " Caution! Hot " at this time Case is then shown at this time when the temperature in liner 12 is more than discoloring temperature in the pre-set color different from the color of liner 12 The prompting pattern of the prompting text and high temperature warning mark of " Caution! Hot " out.Certainly, in other embodiments, photochromic layer 14 Other can also be formed to remind text and remind pattern.
