The present invention relates to a thermochromic frying pan which can be easily fitted and promotes safety in use as well as such that the thermochromic pigment is not easily peeled from the handle.

The present invention is composed of a main body having a constant volume for cooking food, and a handle connected to the main body for gripping, the tip of the handle in the frying pan 10 is provided with a metal handle head in direct contact with the main body , The entire surface of the metal handle head is coated with a thermochromic pigment that changes color depending on the heat, so that the color of the entire surface of the handle head changes when heat is conducted from the body.

Description

Thermochromic frying pan {omitted}

The present invention relates to a thermochromic frying pan, and more particularly, by coating a thermochromic pigment on the entire handle head of a metal material in direct contact with the frying pan body so that heat is transferred from the frying pan body to the handle side to visually discolor the handle head. The frying pan can be easily recognized to be heated, so that the cooking temperature can be easily adjusted and the safety of use can be achieved, and the thermochromic pigment is not easily peeled off from the handle.

As is well known, a frying pan is a type of cooking vessel used for baking or frying foods, and the temperature is very high because oil is used when cooking the frying pan.

In addition, foods that are baked or fried are usually put in a frying pan, and the food ingredients are put into a frying pan and cooked in a faster time so that the moisture or oil of the food ingredients is trapped inside the baked or fried foods to maintain the unique taste of the food. The food should be cooked evenly.

However, since a general frying pan cannot discern visually how much the heating temperature is, it relies solely on the cooker's sixth sense. Therefore, it lacks safety in use and reduces the flavor of cooked food when the input time of food ingredients is missed. May result.

Therefore, some manufacturers cover the bottom surface of the frying pan with a thermochromic pigment that changes color depending on the heating temperature of the frying pan, and visually confirm that the color of the thermochromic pigment changes when the frying pan is heated to an appropriate temperature. The company has launched a frying pan to make food cooking easier while maintaining safety.

However, when the thermochromic pigment is coated on the bottom surface of the frying pan main body, there is a problem that the thermochromic pigment is easily peeled off from the frying pan main body due to frequent friction with food. It could be included and could adversely affect people who eat cooked food.

In view of this, Korean Utility Model Registration No. 334304 discloses a cooking vessel handle having a temperature-sensitive display function for the purpose of safety by forming a thermally conductive portion on the upper surface of the frying pan handle and a thermally conductive pigment portion on the upper surface of the frying pan handle. .

However, since the cooking container according to the Utility Model No. 334304 is simply attached to the upper surface of the thermal conductive part in the form of a sticker, the frying pan can be easily crushed by a scrubber or other external impact when washing the frying pan. There is a problem that can be peeled off from the handle, there is no heat conductive pigments attached only to the upper surface of the handle of the frying pan, there is no way to check the current state of the frying pan at a long distance, and also need to configure a separate heat conductive part when the handle is configured There was a problem.

The present invention can cover the entire handle head of the metal material in direct contact with the frying pan body by spraying or the like, so that the whole handle head discolors when heat is transferred from the frying pan body to the handle side, thereby improving safety. In addition, the present invention is to provide a thermochromic frying pan which can easily check the current temperature state of the frying pan with a short distance or a long distance, and does not easily peel off the thermochromic pigment from the handle even when washing dishes or an external shock.

In order to solve this problem, the present invention is made of a metal material to cover the entire surface of the handle head which is in direct contact with the frying pan main body and heat transfer from the frying pan body when the thermochromic pigment is discolored to visualize the temperature of the frying pan It is to be confirmed as.

In the present invention, since the thermochromic pigment is coated on the entire surface of the handle head made of metal, when the heat is conducted from the frying pan body, the entire head is discolored so that the temperature of the frying pan can be easily checked with the naked eye at a short or long distance. Since the pigment is coated on the handle head by the spraying method, the handle head and the thermochromic pigment are integrated and the thermochromic pigment is not easily peeled off from the handle head even when washing dishes or external shocks. There is an advantage that can be applied to the handle as it is.

Hereinafter, the present invention will be described in detail with reference to the embodiments presented and the accompanying drawings.

1 is a perspective view of a frying pan according to the present invention, Figure 2 is a cross-sectional view taken along the line A-A of FIG.

As shown, the frying pan 10 to which the present invention is applied is composed of a main body 11 having a constant volume for cooking food, and a handle 12 connected to the main body 11 for gripping. The tip end portion 12 is provided with a metal handle head 13 in direct contact with the main body 11.

In the frying pan 10, the entire surface of the metal handle head 13 is coated with a thermochromic pigment 14 that changes color depending on the heat when heat is conducted from the main body 11 so that heat from the main body 11 is reduced. When turned over, the color of the entire surface of the handle head 13 is configured to change.

At this time, the thermochromic pigment 14 applied to the present invention is dissolved and synthesized through a solvent such as MEK, DMF to obtain a constant color and then mixed with acrylic transparent paint (thermosetting transparent paint) which is a secondary mixture and coated with a spray The transparent coating film can be configured to be resistant to external impact while being transparent to the thermochromic pigment, and the thermochromic pigment 14 is sprayed onto the handle head 13 of the frying pan 10 by a spray method. Anything that can be covered is applicable.

In addition, when the thermochromic pigment 14 is selected, a pigment having a required temperature within a range of 80 to 200 ° C. is used to give a cooking time by turning white to black and red to white to indicate a cooking time. You can get a change.

In addition, although not shown, it is apparent that the thermochromic pigment 14 may be coated on the entire surface of the handle head 13, and then the transparent paint may be coated on the surface to form a more robust structure.

When the frying pan 10 is placed in a gas range or a burner and ignited in such a configuration, the body 11 is gradually heated, and the heat is conducted to the handle head 13 which is in direct contact with the body 11. When the temperature of the head 13 is above a certain temperature, the color of the thermochromic pigment 14 coated on the entire surface of the handle head 13 changes.

At this time, since the thermochromic pigment 14 is coated on the entire surface of the handle head 13, it is easy to visually confirm that the frying pan 10 is currently heated even when viewed from a short distance from a short distance. In addition to ensuring safety, the cooker's activity radius can be widened during cooking, and delicious cooking becomes possible.

In addition, since the thermochromic pigment 14 is integrally coated on the surface of the handle head 13 by a spraying method or the like, the thermochromic pigment 14 is easily removed from the handle head 13 even when washing dishes or when an external shock is applied. It does not peel off can be used for convenience, as well as the advantage of extending the life of the frying pan 10.

In the present invention, the thermochromic pigment 14 is coated on the handle head 13 of the frying pan 10. However, in some cases, the thermochromic pigment 14 is not only a frying pan but also a pot, a pot, As it can be applied to the handle of the same various cooking vessels, it is obvious that all such modified embodiments also belong to the scope of the present invention.
