Thermochromic device, kitchen range and electric heating household cooking utensil

Abstract

The invention provides a thermochromic device, a kitchen range and an electric heating household cooking utensil, and is applied to the technical field of kitchen electric appliances. The thermochromic device is adapted to be arranged on an electrical appliance substrate with a heating function, and comprises at least a thermochromic coating composed of a reversible thermochromic substance, wherein the reversible thermochromic substance comprises at least a thermochromic material, a flame retardant, colored ink and an organic solvent; and when the kitchen range is used, heat is transferred tothe thermochromic coating, so that the thermochromic coating displays colors in segmentation. The kitchen range comprises a kitchen range body and a thermochromic device, and the thermochromic deviceis arranged on a pot frame and / or a panel of the kitchen range body. The kitchen range alleviates the problems that when the thermochromic coating is directly sprayed on the kitchen range, the ageingresistance is poor, the color-changing display is not clear, and thermochromic material will be aged and decomposed in the long-term operation, so that poor experience is brought to consumers..

Description

technical field [0001] The invention relates to the technical field of kitchen appliances, in particular to a temperature display and color display device, a stove and an electric heating household cooking appliance. Background technique [0002] When cooking in the kitchen, because the thermal efficiency of the stove is not high and a large amount of waste heat is absorbed by the stove panel and the pot frame, the temperature is relatively high. Generally, the panel can reach above 100°C, while the lower surface temperature of the pot frame is higher, reaching 150°C. For example, when using an electric pressure cooker or electric rice cooker, the local temperature of the surface of the pot body will also reach above 70°C, and when using an electric oven or electric cake stall, the temperature on the upper surface will easily reach above 70°C. When the consumer turns on the cooking utensil after cooking, or cleans the stove in a short period of time, the consumer does not kn...

AI Technical Summary

Problems solved by technology

When consumers turn on cooking utensils after cooking, or clean the stove in a short period of time, consumers do not know the surface temperature status, and it is easy to touch these high-temperature surfaces and be scalded by the high temperature

In order to avoid being scalded, some heat insulation measures are used to reduce the surface temperature, but it is easy to cause a substantial increase in cost and the effect is not obvious. For gas cookers, heat insulation measures are difficult to have obvious effects, so it is intuitive To remind consumers of the temperature status of the surface of the cooker panel and the pot support, the measure to be taken is to coat the bottom of the panel or the pot support with a temperature-indicating material, which displays different colors under different conditions of high and low temperature

[0003]In the prior art, the temperature-indicating paint is usually directly sprayed and transferred to the cooker, which has poor anti-aging performance, resulting in unclear discoloration and display. Will age and decompose, giving consumers a poor experience
