Anti-fog mirror, cooking appliance and making method of anti-fog mirror

Abstract

The invention provides an anti-fog mirror for a cooking appliance, the cooking appliance and a making method of the anti-fog mirror for the cooking appliance, wherein the anti-fog mirror for the cooking appliance comprises a glass layer and a super-hydrophilic coating; the glass layer is a tempered glass layer or a half-tempered glass layer; the super-hydrophilic coating coats the surface of the glass layer; and the super-hydrophilic coating is a coating which is applied to the surface of the glass layer and is formed by a mixture of silica sol and titanium dioxide sol or by silica sol. According to the technical scheme provided by the invention, the anti-fog mirror is excellent in anti-fog effect, and the anti-fog mirror is relatively high in hardness and relatively good in wear-resistingproperty; and the anti-fog mirror, when working in a dark condition, can keep an anti-fog performance for a long time.

Description

technical field [0001] The invention relates to the technical field of cooking utensils, in particular to an anti-fog mirror for cooking utensils, a cooking utensil and a method for preparing the anti-fog mirror for cooking utensils. Background technique [0002] With the continuous development of cooking utensils (such as electric rice cookers, etc.), users hope to be able to observe the changes of the food in the cooking utensils during the cooking process. Observe, specifically because the high-temperature water vapor generated during the cooking process will adhere to the glass surface when it encounters cold glass during the volatilization process, and the contact angle between water droplets and ordinary glass is generally about 37°, so due to the refraction of light, As a result, a layer of water mist will be formed on the surface of the glass, which directly affects our sight, thereby affecting our observation of changes in the food in the cooking utensil. Moreover,...

[0002] With the continuous development of cooking utensils (such as electric rice cookers, etc.), users hope to be able to observe the changes of the food in the cooking utensils during the cooking process. Observe, specifically because the high-temperature water vapor generated during the cooking process will adhere to the glass surface when it encounters cold glass during the volatilization process, and the contact angle between water droplets and ordinary glass is generally about 37°, so due to the refraction of light, As a result, a layer of water mist will be formed on the surface of the glass, which directly affects our sight, thus affecting our observation of the changes in the food in the cooking utensils

Moreover, a super-hydrophilic coating alone is not enough to achieve the above purpose, only anti-fog and transparent glass can meet the needs of users to be able to observe the changes of food during the cooking process

[0003] However, the current methods of removing water mist on the surface of glass mirrors mainly include electrothermal method and photocatalytic method. Among them, the electrothermal method mainly achieves the anti-fog effect by adding a heating device. Water pipe or electric heating wire, that is, through hot water supply and electric heating, the glass can achieve anti-fog effect. However, this method is difficult to install, wastes resources and is expensive, which greatly reduces its practicability.

[0004] The photocatalytic method is mainly to coat a layer of photocatalytic active substances on the glass surface, such as TiO2 (titanium oxide), ZnO (zinc oxide), etc. Although the purpose of saving energy can be achieved, these photocatalytic active substances can only be used under light conditions. In order to maintain the hydrophilic property, the anti-fog effect can be achieved, that is, the photocatalytic active substance can make the coating change from the hydrophobic state to the hydrophilic state under the irradiation of ultraviolet light, thereby playing the role of anti-fog. It can be seen that the The hydrophilicity of the coating is extremely unstable. For example, under dark conditions, due to the lack of ultraviolet light on the coating, the coating does not have hydrophilic properties at this time, which greatly limits its application.

[0005] Therefore, a new anti-fog mirror is needed to effectively solve the problem that the anti-fog mirror for cooking utensils is easy to generate water mist
