    "2. The cooking appliance of claim 1, wherein the fastening part comprises a bolt member that passes through the hinge part and a coupling surface of the hinge coupling part in an up-down direction, and a nut member that is coupled to the bolt member and fixes the hinge part to the coupling surface of the hinge coupling part, and the fastening part is coupled to the position adjustment guide part.",
    "3. The cooking appliance of claim 2, wherein the hinge coupling part comprises the coupling surface that forms a surface facing the hinge part in the up-down direction, and a fastening hole that penetrates the coupling surface in the up-down direction, wherein the bolt member passes through the coupling surface through the fastening hole in the up-down direction; and the position adjustment guide part comprises a fastening hole that has a front-to-rear length greater than a diameter of the bolt member.",
    "4. The cooking appliance of claim 3, wherein the position adjustment guide part further comprises a fastening and guiding groove that is recessed from a surface opposite from the coupling surface of the hinge coupling part, and at least a portion of the nut member is disposed in the fastening and guiding groove.",
    "5. The cooking appliance of claim 4, wherein a front-to-rear length of the fastening and guiding groove is greater than a maximum diameter of the nut member.",
    "6. The cooking appliance of claim 5, wherein the at least a portion of the nut member is disposed in to the fastening and guiding groove movable in a front-rear direction.",
    "7. The cooking appliance of claim 6, wherein the nut member is formed as a polygonal pillar, and the fastening and guiding groove interferes with the nut member to limit a rotation of the nut member.",
    "8. The cooking appliance of claim 1, wherein the cooking appliance comprises a door frame coupled under the door, and the hinge coupling part is disposed at the door frame.",
    "9. The cooking appliance of claim 8, wherein the door comprises: a door upper surface part to cover the open upper surface of the housing, and a door front surface part connected to a front side of the door upper surface part to cover the open front surface of the housing.",
    "10. The cooking appliance of claim 9, wherein the door swivels around a rear side of the door upper surface part to open and close the open upper surface and the open front surface of the housing.",
    "11. The cooking appliance of claim 9, wherein the cooking appliance comprises a first heating part that is disposed at the door; and the door frame comprising a heater mounting part to which the first heating part is mounted, and a coupling part that is coupled to the door upper surface part and allows the heater mounting part to be supported by the door upper surface part.",
    "12. The cooking appliance of claim 11, wherein the hinge coupling part is disposed at the coupling part.",
    "13. The cooking appliance of claim 11, wherein the fastening part comprises a bolt member that couples the hinge part to the door frame while passing through the hinge part and the coupling surface of the hinge coupling part in the up-down direction, and a nut member that is coupled to the bolt member and fixes the hinge part to the coupling surface of the hinge coupling part, and the fastening part is coupled to the position adjustment guide part.",
    "14. The cooking appliance of claim 13, wherein the bolt member and the nut member are coupled in a state in which a head of the bolt member is disposed under the coupling surface of the hinge coupling part and the nut member is disposed on a surface opposite to the coupling surface of the hinge coupling part; and the position adjustment guide part further comprises a fastening and guiding groove that is recessed from the surface opposite to the coupling surface of the hinge couple part, wherein at least a portion of the nut member is disposed in the fastening and guiding groove.",
    "15. The cooking appliance of claim 14, wherein the fastening and guiding groove and the nut member are disposed in a space between the door upper surface part and the door frame, and the bolt member passes through the coupling surface of the hinge coupling part upward and is coupled to the nut member in the space between the door upper surface part and the door frame.",
    "16. The cooking appliance of claim 1, wherein depending on a front-to-rear position of the fastening part being coupled to the position adjustment guide part, a gap between the front surface of the housing and the door front surface part is adjusted."

  "description_excerpt": "Disclosed herein is a cooking appliance.\n\nCooking appliances are installed in the kitchen and cook food as a user intends. The cooking appliances can fall into different categories, based on a heat source or a type, and the sort of fuel.\n\nAdditionally, the cooking appliances can be categorized into an open cooking appliance in which food is placed in an open space, and a sealed cooking appliance in which food is placed in a closed space, based on a way of cooking food. The sealed cooking appliance includes an oven, a microwave oven and the like, and the open cooking appliance includes a cooktop, a hob, and the like.\n\nIn the sealed cooking appliance, a space, in which food is placed, is shielded, and the shielded space is heated to cook food. The sealed cooking appliance is provided with a cooking space in which food is placed and which is shielded when the food is cooked. In the cooking space, food is actually cooked.\n\nThe sealed cooking appliances are broadly classified into gas ovens and electric ovens according to the type of heat source. The gas ovens use gas as a fuel and cook food using flames generated as gas is supplied to a plurality of burners, and the burners are ignited, which burns the supplied gas. Unlike the gas ovens, the electric ovens use electricity as a heat source and cook food using heat emitted from a plurality of heaters, which are heated by the electricity.\n\nOf the gas ovens and the electric ovens, the use of the electric ovens has increased due to a faster cooking speed, higher thermal efficiency, and better stability when compared with the gas ovens.",
