Cooking device having cooking glass bowl and handle structure thereof

A grip structure of a cooking instrument having a glass cooking bowl, in which at least one grip base is extended and formed integrally on an outer face of the glass cooking bowl,

• wherein the grip structure comprises first and second grip portions assembled and fixed with a close contact with each other to enclose the grip base with maintaining a close contact status in a vertical direction with respect to an outer circumferential face of the glass cooking bowl and
• wherein the first and second grip portions comprise:
• first and second base portions which are in a close contact with each other and are assembled to form a bilateral symmetry structure, wherein each of first and second upper openings and first and second lower openings is formed at an upper end portion and a lower end portion of the first and second base portions such that the grip base penetrates in an assembled status, and first and second bending ends bent in a perpendicular direction along the outer circumferential face of the glass cooking bowl are extended and formed at the first and second base portions in a lateral direction in a predetermined length such that a predetermined heat declining space is formed between the first and second base portions and the outer circumferential face of the glass cooking bowl in a status where the first and second base portions are fixed to the outer circumferential face of the glass cooking bowl;
• an upper plate extended and formed integrally at an upper portion of the first or second base portions in a horizontal direction, wherein a sensor installation aperture is formed at the upper plate, either a temperature detecting or open-close detecting sensor for detecting opening and closing of the glass cooking bowl is fixed and installed at the lower face of the sensor installation aperture, and the upper plate covers an upper portion of the first or second bases when the first and second base portions are assembled;
• and
• first and second grip pipes assembled with a close contact with each other, wherein first and second gripping openings are formed, in an assembled status, at a center portion of the first and second grip pipes, the first and second grip pipes are extended and formed integrally with the first and second base portions and the upper plate while a grip base installation space in which the grip base is inserted is formed, each of a first upper engaging protrusion and a first lower engaging protrusion is projected and formed at a position where the first upper opening and the first lower opening contact, and each of a second upper engaging protrusion and a second lower engaging protrusion is projected and formed at a position where the second upper opening and the second lower opening contact.
