The present invention relates to an inner pot for an electric pressure cooker, and more particularly, to an inner pot for an electric pressure cooker having an improved taste and food preservation by coating elvan rock with far-infrared rays emitted from the inner side of the inner pot.

Beta (β) starch, which is the main component of rice, is difficult to dissolve in water and difficult to absorb. Therefore, rice is cooked to change beta (β) starch to alpha (α) starch which is easy to digest. In this way, by changing the beta (β) starch to alpha (α) starch, the digestive absorption rate is improved by about 10 times.

At this time, one of the household appliances used to luxury the rice to rice is an electric pressure cooker. In general, an electric pressure cooker is a device that uses a heat source to obtain a heat source and cooking while maintaining the inside of the inner pot at a high pressure state using the heat source, the electric pressure cooker is cooking food in the inner pot by the heat generated from the hot plate. There is an induction heating method for cooking food in the inner pot by generating a method and an induction current.

Hereinafter, the structure of the conventional electric pressure cooker and the structure of an inner pot are demonstrated.

1 is a perspective view of a conventional electric pressure cooker.

As shown in Figure 1, the electric pressure cooker is an inner pot of the upper open type for storing food to be cooked or kept warm by the heating means provided in the main body 10, the interior of the main body 10, the predetermined seating space ( 20) is hinged to the upper portion of the main body 10 is configured to include a lid 30, etc. of the main body to selectively open and close the inner pot 20 while rotating up and down.

Here, the front of the main body 10 is provided with an operation panel 12 for receiving an operation signal for the operation of the electric pressure cooker, and displays various information about the operation of the electric pressure cooker to the outside. And inside the electric pressure cooker corresponding to the rear of the operation panel 12 is provided with a variety of electrical elements associated with the operation of the electric pressure cooker is provided with a microcomputer (not shown) for controlling the operation of the pressure cooker.

The configuration of the inner pot employed in the electric pressure cooker configured as described above will be described with reference to FIG. 2.

2 is a cross-sectional view and a partially enlarged view of a conventional inner pressure cooker for an electric pressure cooker.

As shown in FIG. 2, the inner pot includes an aluminum disc layer 21, an exterior coating layer 23 formed by exterior coating with an exterior material on the outer surface of the aluminum disc layer 21, and an aluminum disc layer 21. The primer coating layer 25 applied to improve the adhesion of the coating layer on the inner side of the) and the Teflon layer 27 for coating food on the inner wall of the inner pot is coated with Teflon on the surface of the primer coating layer 25 It is configured to include.

However, when cooking rice using the inner pot 20 configured as shown in Figure 2, because the cooking process is carried out only by the control of water and fire (heat or thermal power) is not enough heat transfer to the inside of the rice rice The problem remains that the core remains.

Therefore, in order to solve this problem, the development of the inner pot and the excellent heat conductivity inner pot of the material capable of producing good taste and good health by transferring heat to the inside of the rice is actively being developed.

For example, Korean Patent Laid-Open Publication No. 10-2006-15427, In the inner pot for the electromagnetic induction heating rice cooker, includes an inner container body of a natural stone material with an open upper surface, and an aluminum outer body cast on the outside of the inner container body; In addition, the inner surface of the aluminum outer body is disclosed an inner pot for electromagnetic induction heating cooker, characterized in that the magnetic film capable of generating heat by the magnetic force line by the induced current is coated.

However, the conventional inner pot for electromagnetic induction heating rice cooker configured as described above has the following problems.

In other words, by using natural stone, such as jade or mudstone that is far-infrared radiation is not coated on the aluminum outer body as a main material forming the body of the inner pot, there is a problem that the production cost increases.

In addition, since the weight of the gemstone or gobstone is much heavier than that of aluminum or stainless steel, not only the user's wrist is exerted in the process of removing the inner pot to cook rice, but also the inconvenience of handling and using due to the weight.

Therefore, the present invention has been devised to solve the conventional problems as described above, the object of the present invention is a thin coating of ganban stone on the inner surface of the inner pot to emit a large amount of infrared radiation, which is beneficial to health, to improve the state of luxury of rice, It is to provide an inner pot for an electric pressure cooker capable of cooking food in a shorter time by inputting less energy.

Another object of the present invention is to further form a gold sparkle layer on the ganban stone coating layer to form a second top coating layer, the inner aesthetics of the inner surface of the inner pot more beautiful and delaying the peeling of the ganban stone coating layer inner pot for improved durability To provide.

In order to achieve the above object, the present invention is an inner pot for an electric pressure cooker including a disc layer, the ganban stone coating layer is formed on the inner surface of the disc layer, the ganban stone coating layer comprises a ganban stone and a primer It provides an inner pot for an electric pressure cooker, characterized in that.

Preferably, a teflon coating layer and a gold sparkling layer are further formed on the inner surface of the elvan, and the components of the gold sparkling layer include perfluoralkoxy (PEA) and mica.

At this time, preferably the outer coating layer is further formed on the outer surface of the disc layer.

Further, preferably, the disc layer is formed of a single layer of aluminum or an aluminum layer and a double layer of a stainless steel layer integrally formed with the aluminum layer on the outer surface of the aluminum layer.

In addition, the thickness of the lamellar coating layer is preferably 3㎛ ~ 50㎛.

According to the inner pot for the electric pressure cooker of the present invention configured as described above, by coating the inner surface of the aluminum disc layer with the elvan is released can improve the geological state of the rice, improve the thermal conductivity to cook food or keep warm Not only can you save energy, but you can prepare food in less time.

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

3 is a cross-sectional view and a partially enlarged view of the inner pot for an electric pressure cooker according to the present invention.

As shown in Figure 3, the inner pot for the electric pressure cooker according to the present invention is a disc layer 111 formed of aluminum, the outer coating layer 113 formed on the outer surface of the aluminum disc layer 111 and the aluminum disc layer ( It is configured to include the elvan coating layer 115 formed on the inner side of the 111.

The exterior coating layer 113 is formed to prevent corrosion of the inner pot and to minimize the adsorption of food or foreign matter. The exterior coating layer 113 is formed of a general exterior material used for the inner pot of the electric pressure cooker, and is formed by spraying the exterior material with a spray gun on the outer surface of the aluminum disc layer 111.

Similarly, the elvan coating layer 115 is also formed by spraying a substance containing elvan on the inner surface of the aluminum disc layer 111 with a spray gun. At this time, the main component of the elvan coating layer 115 is a primer, and the elvan coating layer 115 may be well adhered to the inner side of the aluminum layer 111 by the primer component. The amount of elvan is preferably 1 to 10 wt (%), and the amount of elvan can be adjusted in some cases.

On the other hand, the thickness of the lamellar coating layer 115 is preferably 3㎛ ~ 50㎛, because less than 3㎛ does not emit sufficient far infrared rays, if it exceeds 30㎛ the cost required for the elvan material increases. Therefore, the ganbanite coating layer 115 is preferably formed to a thickness of 3㎛ ~ 50㎛ so as not to emit a large amount of far infrared rays and not increase the raw material ascent ratio.

The present invention, unlike the prior art by coating the ganban stone on the inner surface of the aluminum disc layer 111 to form a ganban stone coating layer 115, by forming a ganban stone coating layer 115 in this way it can evenly transfer heat to the core of the rice. I can cook rice which is in good condition.

That is, in the process of making rice, far infrared rays emitted from the ganbanite coating layer 115 penetrate into the inside of the rice, and the penetrated far infrared rays cause self-heating at the deep portion of the rice, and directly and instantaneously transfer radiant heat to the depths of the rice to make the inside and outside of the rice. It can heat rice with good gelatinization because it heats uniformly.

In addition, by forming the elvan rock coating layer 115 on the inner surface of the aluminum disc layer 111, the agent effect by the elvan rock appears.

For example, when far infrared rays around 10 μm, which are the wavelength bands of water molecules, are irradiated from elvan, water molecules are activated by resonance and absorption. The activated water molecules prevent dissolved food from activating dissolved oxygen. Therefore, food can be kept fresh for a long time.

In addition, the water molecules activated during the far-infrared irradiation are uniformly spread inside the material, which not only prevents the drying of food, but also suppresses the occurrence of mold and improves hydration, and decomposes mesopolite.

In addition, the far-infrared rays emitted from the ganguerite penetrates deeply into the material (rice), causing self-heating at the core to uniformly heat the inside and outside of the material, thereby efficiently heating food and saving energy.

After forming the ganbanite coating layer 115 that emits far infrared rays, which are beneficial to health, Teflon is sprayed on the surface of the ganbanite coating layer 115 to form a Teflon coating layer 117. The Teflon coating layer 117 is a first top coating layer, and if it is coated on the inner side of the inner pot, food may be prevented from being adsorbed on the inner wall of the inner pot.

On the other hand, it is more preferable to form a gold sparkling layer 119 by spraying a liquid or powder material on the surface of the Teflon coating layer 117 with a spray gun.

Here, the components forming the gold sparkling layer 119 include perfluoroalkoxy (hereinafter referred to as 'PEA') and mica. PFA is a fluororesin-based high-performance plastic capable of injection molding, and is widely used in chemical industry, semiconductor industry, nuclear vacuum and electric and electronic industry because of excellent chemical resistance, water resistance, mold release property and weldability. In addition, mica is excellent in insulation, very light, and has an insulating effect.

When the inner pot is fired in a high-temperature furnace, the PFA is fused and transparent, and the mica mixed in the PFA mass is shiny on the inner side of the inner pot while displaying a gold color.

As described above, when the gold sparkle layer 119 is coated on the inner side of the inner pot to form the second top coating layer, the gold color appears discretely on the inner side of the inner pot to make the exterior look beautiful. In addition, the first top coating layer 117 is formed on the inner side of the inner pot with a teflon, and then the second top coating layer 119 is formed thereon, thereby delaying the peeling of the lamellar coating layer 115. Can improve.

On the other hand, Figure 4 relates to a cross-sectional view and an enlarged view of the inner pot for an electric pressure cooker according to another embodiment of the present invention, unlike Figure 3 is made of an aluminum layer 121 and a stainless steel layer 122. The inner pot having the disc layers 121 and 122 configured as described above is mainly employed in the inner pot for the electromagnetic induction heating cooker.

In the case of the inner pot for the electromagnetic induction heating cooker, the induction current transmitted through the stainless steel layer 122 is transmitted to the inner aluminum layer 121, and the food is cooked.

Here, an outer coating layer 123 coated with an outer material is formed on the outer surface of the stainless steel disc layer 122 to prevent adsorption of foreign substances, and the elvan coating layer 125 on the inner side of the aluminum disc layer 121 as in FIG. 3. ), The Teflon coating layer 127 and the gold sparkle layer 129 are formed in this order.

As such, the present invention can be applied not only to a disc layer formed of aluminum alone, but also to a disc layer formed of a double layer of an aluminum layer and a stainless steel layer, so that the present invention is not only an electric pressure cooker for cooking food by a hot plate method but also an electromagnetic induction heating method. It can also be applied to the electric pressure cooker for cooking food by.

Hereinafter, the far-infrared dose emitted from the inner pot for an electric pressure cooker according to the present invention will be described with reference to FIGS. 5A, 5B, 6A, and 6B.

Figure 6a is a graph showing the radiation energy of the far infrared rays radiated from the conventional inner pressure cooker for electric pressure cooker, Figure 6b is the wavelength of the far infrared radiation emitted from the inner pot for electric pressure cooker according to the present invention It is a graph showing the area. At this time, the lamellar coating layer contains 1wt% of elvan rock.

Referring to these test reports and graphs, in the conventional inner pot, in which only Teflon is coated on the inner surface of the aluminum disc layer, the far-infrared emissivity in the 0-20 μm region is 0.732 and the radiant energy of the far-infrared ray is 8.62 × 10 ² W / 130 ° C. On the other hand, in the inner pot of the present invention, in which the elvan coating layer was formed on the inner side of the aluminum disc layer and top-coated with Teflon, the far-infrared emissivity was 0.818, and the radiation energy was 9.63 × 10 ² W / ㎡ · μm at 130 ° C. You can see that.

In particular, the maximum radiant energy is emitted in the wavelength range of about 8 ㎛ far infrared rays, while the maximum energy emitted by the conventional inner pot is about 90 W / ㎡ · ㎛ (see FIG. 6A), while in the inner pot of the present invention is about 115 W / ㎡ · It can be seen that the radiation energy of about (μm) (see Figure 6b) is emitted.

Therefore, according to the present invention in which the elvan coating layer is formed on the inner side of the aluminum disc layer, the far-infrared emissivity and the far-infrared radiation energy can be improved by about 10% or more, thereby reducing the energy required during the cooking process or the warming process, and the rice. Gelatinization can also be improved.

However, since the test result is that 1% by weight of ganban rock is formed when the ganban stone coating layer is formed, increasing the amount of ganban stone can further improve the energy saving effect or the gelatinization state of the rice.

According to the present invention it can be seen through Figure 7 that far far infrared radiation energy is emitted to the entire surface of the inner pot than in the prior art.

7 is a view for explaining the distribution of far-infrared radiation energy emitted from the inner pot according to the conventional inner pot and the present invention, the upper part is a conventional inner pot and the lower part is a view according to the present invention.

Radiation energy emitted from far infrared rays increases in order of blue, green, yellow, and red, and the area of deep red shows a greater amount of radiation energy distribution of far infrared rays.

Referring to Figure 7, the conventional inner pot bottom, blue, green, yellow, etc. appear, while the inner pot bottom of the present invention can be seen that emits much far infrared energy from the inner pot according to the present invention.

In addition, it can be seen that the red color appearing in the inner pot according to the present invention is much darker than the red color appearing in the conventional inner pot, and this fact indicates that much far infrared energy is emitted from the inner pot according to the present invention.

According to the inner pot for the electric pressure cooker of the present invention configured as described above, by coating the inner surface of the aluminum disc layer with the elvan is released can improve the geological state of the rice, improve the thermal conductivity to cook food or keep warm Not only can you save energy, but you can prepare food in less time.
