Patent Description:
Induction devices (induction heating devices) are being used as heat sources to generate heat. In particular, an induction heating cooking apparatus is used as a cooking apparatus for heating food using an induction heating apparatus.

In general, an induction heating cooking apparatus is a cooking apparatus that heats and cooks a food container using the principle of induction heating. The induction heating cooking apparatus may include a glass on which the food container is placed, and an induction heating coil that is arranged below the glass and generates a magnetic field when an electric current is applied.

When a current is applied to the induction heating coil and a magnetic field is generated, a secondary current is induced in the food container, and Joule heat is generated by the electrical resistance component of the food container itself. Joule heat heats the food container and heats the food in the food container.

Compared to gas stoves and kerosene furnaces that burn fossil fuels such as gas or oil and heat the food container through the heat of combustion, such induction cooking apparatus has the advantages of rapid heating, no harmful gases, and no risk of fire.

The glass of the induction heating cooking apparatus not only has a cooking area where the food container is placed, but also has a control area where various information is displayed and control commands are input from the user.

<CIT> discloses a cooking apparatus according to the preamble of claim <NUM>.

With the coupling of the first coupling member <NUM> and the second coupling member <NUM>, the second glass <NUM> may be coupled to the first glass <NUM> along the same line.

The sealing member <NUM>, which is positioned between the first glass <NUM> and the second glass <NUM>, has a first portion <NUM> arranged to seal between the side 100b of the first glass <NUM> and the side 120b of the second glass <NUM> to prevent foreign matter from entering between the first glass <NUM> and the second glass <NUM>.

In addition, the second portion <NUM> of the sealing member <NUM> is provided to extend to the second glass <NUM> side, which may prevent foreign matter entering between the first glass <NUM> and the second glass <NUM> from moving to the second glass <NUM> side.

Also, although not shown, a sealing member may be additionally applied to the upper portion <NUM> of the first portion of the sealing member <NUM>, that is, between the first glass <NUM> and the second glass <NUM>, to prevent dust or liquid/foreign matter or the like from entering between the first glass <NUM> and the second glass <NUM>.

<FIG> is a drawing illustrating a sealing member according to another embodiment of the present disclosure, and <FIG> is an enlarged view of a joining portion of the first glass and the second glass equipped with a sealing member according to another embodiment of the present disclosure. For components identical to the foregoing embodiments, the same drawing symbols may be given and the description may be omitted.

As shown in <FIG> and <FIG>, a sealing member 500A may be arranged to seal between the first glass <NUM> and the second glass <NUM>.

The sealing member 500A may be mounted between the first glass <NUM> and the second glass <NUM>. The sealing member 500A may be formed of a rubber material. The sealing member 500A may be mounted on the coupling device <NUM>, which is arranged to detachably couple the first glass <NUM> and the second glass <NUM>.

The sealing member 500A may be mounted to a first coupling member <NUM> that is secured to a bottom surface 110b of the first glass <NUM>. The sealing member 500A may include a first portion 510A positioned between the first glass <NUM> and the second glass <NUM>, a second portion 520A extending from the first portion 510A and arranged to support a bottom surface 120c of the second glass <NUM>, and a third portion 530A projecting from a bottom of the first portion 510A.

The first portion 510A may be formed to contact between a side 110b of the first glass <NUM> and a side 120b of the second glass <NUM>. The first portion 510A may be formed to contact a vertical surface of the first glass <NUM> and the second glass <NUM>. The first portion 510A is arranged to be contacted between a side 110b of the first glass <NUM> and a side 120b of the facing second glass <NUM>. The first portion 510A may be attached to the side 110b of the first glass <NUM> or the side 120b of the second glass <NUM> via a separate adhesive.

The third portion 530A of the sealing member 500A may be formed by protruding from the bottom of the first portion 510A.

The second portion 520A may be formed by extending in a first direction (X) from the first portion 510A. The second portion 520A may be formed to contact the bottom surface 120c of the second glass <NUM>. The second portion 520A may further include a protrusion 540A formed to protrude upwardly. The protrusion 540A may be formed in plurality. The protrusions 540A may be formed to be sloped to prevent foreign objects entering from the rear from traveling forward. The protrusions 540A may be formed in a plurality spaced apart at predetermined intervals to prevent foreign matter entering through the first portion 510A from moving forward.

The second portion 520A of the sealing member 500A may prevent foreign matter entering between the first glass <NUM> and the second glass <NUM> from moving to the side of the circuit board <NUM> located at the bottom of the second glass <NUM>. The protrusion 540A formed in the second portion 520A of the sealing member 500A may prevent foreign matter entering between the first glass <NUM> and the second glass <NUM> from moving to the side of the circuit board <NUM> located at the lower end of the second glass <NUM>. In an embodiment of the present disclosure, four protrusions formed in the second portion of the sealing member are shown as an example, but the ideas of the present disclosure are not limited thereto. The protrusions are intended to prevent the entry of foreign matter moving in a horizontal direction, and the shape and number of protrusions may be formed in various ways.
