In addition, since the user can input the cooking execution by voice through the control unit 600, the user can cook while doing other work, thereby enhancing the convenience of use.

In addition, cooking can be started with only one operation in the application of the display unit 700, and the amount of water and rice can be adjusted by the application, so that the operation of the rice cooker can be more efficiently controlled.

In addition, since food is inserted into the accommodating part 110 of the present invention, it is preferable that a coating layer to prevent corrosion is formed inside the accommodating part 110 .

The coating layer (not shown) is to be coated using a coating composition, and the coating layer using the coating composition may exhibit an anti-corrosion effect. Specifically, the coating layer is formed on the inside of the receiving unit 110 by the coating layer to prevent external exposure of the inside of the receiving unit 110, and contains a metal having a higher ionization tendency than the inside of the receiving unit 110, Thereby, it is possible to prevent corrosion of the inside of the receiving unit 110 .

More specifically, the coating composition of the present invention may include a siloxane-based compound represented by the following Chemical Formula 1; organic solvents, metal compounds and amine compounds:

[Formula 1]

Here, n is an integer from 1 to 100.

When the coating layer is formed on the inner surface of the receiving unit 110 by using the coating composition of the present invention, the adhesion to the inside of the receiving unit 110 is excellent, so that the coating layer is not easily peeled off by external force, and the receiving unit By including a metal compound having a higher ionization tendency than the inside of (110), an excellent anti-corrosion effect may be exhibited.

Specifically, since the siloxane-based compound contains a mercapto group as a substituent, it not only exhibits excellent adhesion to the interior of the receiving part 110, but also maintains the viscosity of the coating composition at a certain level to increase moldability and improve stability. can be raised

The metal compound serves as an erosion and corrosion inhibitor that blocks contact with moisture, salt or oxygen. Here, the metal compound may use a metal having a higher ionization tendency than iron in order to act as an erosion and corrosion inhibitor. That is, a metal or alloy such as aluminum (Al), magnesium (Mg), or zinc (Zn) may be used, and zinc (Zn) is mainly used.

The particle size of the metal compound may be 0.1 to 10㎛. When the particles of the metal compound are 0.1 μm or more, the manufacturing cost of the metal compound can be reduced, and when the particles of the metal compound are 10 μm or less, the metal particles can be uniformly dispersed.

The organic solvent is selected from the group consisting of methyl ethyl ketone (MEK), toluene, and mixtures thereof, and preferably methyl ethyl ketone may be used, but is not limited thereto.

The amine compound may include modified aliphatic amines or tertiary amines, and specifically, trimethylamine or aniline may be used. The amine compound may be included in the coating composition to prevent cracking or peeling of the coating film. That is, by increasing the adhesion of the coating layer, the effect of preventing cracking or peeling of the coating film according to use is excellent.

The coating composition may further include a stabilizer as other additives, and the stabilizer may include a UV absorber, an antioxidant, and the like, but is not limited to the above examples and may be used without limitation.

For forming the coating layer, the coating composition may include a siloxane-based compound represented by Formula 1 below; organic solvents, metal compounds and amine compounds.

The coating composition may include 40 to 60 parts by weight of the siloxane compound represented by Formula 1, 20 to 40 parts by weight of the metal compound, and 5 to 15 parts by weight of the amine compound, based on 100 parts by weight of the organic solvent. In the case of the above range, a synergistic effect is expressed to the extent that the water repellency effect due to the interaction of each component has a critical significance, and when it is out of the above range, the synergistic effect is rapidly reduced or almost absent.

More preferably, the viscosity of the coating composition is 1500 to 1800 cP, and when the viscosity is less than 1500 cP, when applied to the surface of the receiving part 110, there is a problem that it is not easy to form a coating layer by flowing down, and when it exceeds 1800 cP There is a problem in that it is not easy to form a uniform coating layer.

[ production example 1: Preparation of coating layer]

1. Preparation of coating composition

A coating composition was prepared by mixing methyl ethyl ketone with a siloxane-based compound represented by the following Chemical Formula 1, zinc and trimethylamine:

[Formula 1]

Here, n is an integer from 1 to 100.

A more specific composition of the coating composition is shown in Table 1 below.

TX1 TX2 TX3 TX4 TX5 organic solvent 100 100 100 100 100 polysiloxane 30 40 50 60 70 metal compound 10 20 30 40 50 amine compounds One 5 10 15 20

(unit weight parts)2. Preparation of coating layer

Typically, an experiment was conducted using aluminum, which is a metal material that easily corrodes, instead of the inside of the receiving unit 110 .

After coating the coating composition of DX1 to DX5 on one surface of 10 × 10 cm aluminum, it was cured to form a coating layer.

Experimental example

1. Surface Appraisal of appearance

Due to the difference in viscosity of the coating composition, after the coating layer was prepared, sensory evaluation was performed on whether a uniform surface was formed. Whether or not a uniform coating layer was formed was evaluated, and evaluation was performed according to the following criteria.

○: uniform coating layer formation

×: Formation of a non-uniform coating layer

TX1 TX2 TX3 TX4 TX5 sensory evaluation × ○ ○ ○ ×

When forming the coating layer, when the viscosity is less than a certain level, a flow occurs on the inner surface of the receiving unit 110, and after the curing process, it is difficult to form a uniform coating layer. Accordingly, there may be a problem in that the production yield is lowered. In addition, even when the viscosity is too high, it is difficult to uniformly apply the composition to form a uniform coating layer.

2. Measurement of corrosion properties

In order to confirm the corrosion characteristics, an aluminum plate without a coating layer was used as a control, and corrosion resistance tests were performed using an aluminum plate with a coating layer of TX1 to TX5.

The aluminum plate was immersed in a beaker containing a 10 wt% CuCl2 aqueous solution, and the degree of corrosion was checked over time.

If the generation of hydrogen gas is confirmed with the naked eye, it will mean that corrosion occurs, and it was confirmed whether corrosion occurred until 24 hours had elapsed.

○: Corrosion

×: No corrosion

TX1 TX2 TX3 TX4 TX5 control corrosion occurs ○ × × × × ○

As a result of the experiment, it was confirmed that the aluminum plate as a control was placed in a beaker and hydrogen gas was generated shortly thereafter, and copper was precipitated in less than 1 hour. In the case of TX1, hydrogen gas was generated after 3 hours, and copper precipitation was confirmed after 6 hours.

In the case of other coating layers, corrosion did not occur even after 24 hours had elapsed, and it was confirmed that there was an excellent effect in preventing corrosion.
