Abstract
The invention relates to a thermochromic coating agent coating method for a heating cooking appliance and a thermochromic heating cooking appliance. The thermochromic heating cooking utensil provided by the invention has an antibacterial effect, and can recognize the cooling degree of the cooking utensil while clearly distinguishing the heating state of the cooking utensil visually, so that a user is more careful about the cooking utensil approaching the heating state, and the damage (burning) of the cooking utensil in the heating state to a human body is reduced.
Description
Technical Field
The present invention relates to a method for applying a thermochromic coating agent to a heating cooking device, and more particularly, to a method for applying a thermochromic coating agent to a heating cooking device in order to clearly identify a heated state after thermochromic, and a thermochromic heating cooking device to which a thermochromic coating agent is applied.
Background
In general, heating cooking appliances as frying pans, barbecue trays, pans, and the like are made of a metal material. In such a heating cooking appliance, a heating cooking appliance has been produced in which a heat-resistant resin coating agent or a ceramic coating agent is coated on a surface portion where cooking food is directly contacted in order to improve heat resistance or corrosion resistance, or a temperature indicating pigment is mixed with these coating agents to enable recognition of a heated state by thermochromic.
As an example of the related art related to a thermochromic cooker for heating, korean patent publication No. 10-1269774 discloses a thermochromic heated body, characterized in that the thermochromic heated body is heated and coated with a coating agent on a surface of the heated body, divided into at least two color parts having different colors, any one of which includes a thermochromic composition including a first color part and a second color part, the first color part being coated such that the coating agent including the thermochromic composition has a color before thermochromic at room temperature, the second color having a color after thermochromic at a predetermined heating temperature, and korean patent publication No. 10-1292555 discloses a thermosensitive cooking appliance, characterized in that a cooking surface of a cooking space surrounding a main body or the cooking appliance as a whole includes a thermosensitive coating formed of a thermosensitive ceramic paint including a temperature indicating pigment, the thermosensitive coating being formed of a thermosensitive ceramic paint, the thermosensitive paint including: according to hydrolysis products and shrinkageThe content of the compound is 5 to 60 wt% of the compound represented by the general formula R n Si(OR’) 4-n An alkoxysilane represented by the formula; 1 to 40% by weight, based on the solid content, of a colloidal compound containing water or an organic solvent as a dispersion medium; 0.1 to 20% by weight of a lower alcohol; 0.01 to 3% by weight of an organic or inorganic acid; 0.1 to 35% by weight of an inorganic filler; 0.1 to 25% by weight of an inorganic pigment; and 0.1 to 10 wt% of a temperature indicating pigment, the heat sensitive coating is discolored due to heat transferred to the cooking appliance, thereby exhibiting a temperature change of the cooking appliance, and at the same time, heat is transferred to the cooking material through the heat sensitive coating to achieve cooking. Further, korean patent laid-open publication No. 10-0988737 discloses a cooking container, which is characterized by comprising: a main body having an open top and a storage space inside; an upper cover for opening and closing an open top of the main body; a handle portion including a column portion formed in a longitudinal direction at a center of the upper cover, and a handle portion formed long in a width direction with an upper end portion of the column portion as a center; a cover part arranged on the handle part and covering the upper part of the handle part, wherein the thickness gradually increases from the center to the radial direction; and a color-changing member including an edge portion connected to an outer edge of the cover portion and formed in such a manner as to surround an edge of the handle portion, connected to and separated from the handle, made of a silicone rubber material, and changing color according to a temperature transmitted through the handle.
The present invention provides a heating cooking appliance which can clearly recognize the heating state of the cooking appliance after thermochromic while imparting antibacterial properties to the heating cooking appliance which changes color according to temperature.
