[0091] The first contact portion (340) may be provided on the upper part of the handle (300). The first contact portion (340) may be provided as a part where the handle (300) and the door (100) come into contact.

[0092] More specifically, the first contact portion (340) may be provided as a portion where the front surface of the handle (300) and the front panel (120) of the door (100) come into contact.

[0093] Accordingly, the surface where the first contact portion (340) contacts the door (100) can be formed approximately parallel to the front surface of the door (100).

[0094] The first protrusion (320) may be provided to extend rearward from the first contact portion (340) so that a fastening member (400), to be described later, can be inserted into the handle (300).

[0095] More specifically, the first protrusion (320) may be provided in the shape of a boss. Accordingly, the first protrusion (320) may be provided in the shape of a column that forms a space for a fastening member (400) to be inserted inside.

[0096] In other words, the first protrusion (320) may be provided to extend from the first contact portion (340) toward the door (100). The first protrusion (320) may pass through the first handle coupling portion (121) of the front panel (120), which will be described later, and be inserted into the first handle insertion portion (132) of the door frame (130). Further details regarding this will be described later.

[0097] The first guide insertion part (360) may be formed in the first contact part (340). Specifically, the first guide insertion part (360) may be formed by cutting a part of the first contact part (340).

[0098] Additionally, the first guide insertion part (360) may be formed by being recessed inward from the first contact part (340) toward the handle (300).

[0099] The shape of the first guide insertion part (360) can be any shape as long as it forms a space for the first guide projection (134) of the door frame (130), which will be described later, to be inserted.

[0100] The front panel (120) may include a first handle coupling part (121), a first projection passing part (123), and a first support projection (125).

[0101] The first handle coupling portion (121) may be formed by cutting a part of the front panel (120). The first protrusion (320) of the handle (300) may be provided to penetrate the front panel (120) through the first handle coupling portion (121).

[0102] Accordingly, the first handle coupling part (121) may be provided with a size corresponding to the diameter of the first protrusion (320) of the handle (300). However, it is not limited thereto, and the diameter of the first handle coupling part (121) may be provided slightly smaller than the diameter of the first protrusion (320) of the handle (300) to increase the coupling force between the handle (300) and the door (100).

[0103] The first handle coupling portion (121) is cut so that the first protrusion (320) passes through, and can be formed in an area corresponding to the first contact portion (340).

[0104] The first projection passing portion (123) may be formed on the side of the first handle coupling portion (121). The first projection passing portion (123) may be provided so that the first guide projection (134) of the door frame (130) penetrates to the front of the front panel (120).

[0105] Accordingly, the first projection passing portion (123) can be formed at a position corresponding to the first guide projection (134) of the door frame (130).

[0106] The first guide projection (134) can be formed to be biased to one side with respect to the direction in which the handle (300) extends.

[0107] Accordingly, if the handle (300) is incorrectly assembled by being upside down, the handle (300) may be interfered with by the first guide projection (134) penetrating the front panel (120). Through this, the first guide projection (134) can be provided to prevent incorrect assembly of the handle (300) in the upside-down direction.

[0108] The first handle insertion portion (132) of the door frame (130) provided at the rear of the front panel (120) can be extended rearward to accommodate the first protrusion (320) that passes through the first handle coupling portion (121).

[0109] The first support projection (125) may be provided in an area corresponding to the first contact portion (340) of the handle (300). Specifically, the first support projection (125) may be provided to face the first contact portion (340) of the handle (300) when the handle (300) is coupled to the door (100).

[0110] The first support projection (125) may be provided in a circular shape. However, the shape of the first support projection (125) is not limited thereto.

[0111] The first support projection (125) may be formed on the outer side of the front panel (120) than the first handle coupling part (121). When an external force is applied to the front panel (120), the inner side of the front panel (120) may be partially covered by the handle (300).

[0112] However, the outer side of the front panel (120) is a part that is not covered by the handle (300) and can be easily exposed to the user. Therefore, by forming the first support projection (125) outside the first handle coupling part (121), the effect of making the irregularities of the front panel (120) invisible to the user can be further enhanced.

[0113] However, the position of the first support projection (125) is not limited thereto. Also, in FIG. 4, the first support projection (125) is shown as being formed in two on the upper part of the first handle coupling part (121), but the number of the first support projection (125) is not limited thereto.

[0114] For example, the first support projection (125) may not be provided in multiple numbers but may be provided as a single unit. The first support projection (125) may be formed as a single projection in an area corresponding to the first contact portion (340) of the handle (300).

[0115] Additionally, the area where the first support projection (125) is formed is not limited to that shown in FIG. 4, but can be formed anywhere that faces the first contact portion (340) of the handle (300). Of course, the first support projection (125) can also be provided with the same width as the first contact portion (340) of the handle (300).

[0116] The first support projection (125) may be provided to prevent deformation of the front panel (120). More specifically, the first support projection (125) may be provided to prevent the formation of irregularities on the front panel (120) by the tightening force of the fastening member (400) when the handle (300) is coupled to the door (100).

[0117] The first support projection (125) can be extended toward the door frame (130) in an area corresponding to the first contact portion (340) of the handle (300).

[0118] The specific structure of this first support projection (125) will be described later.

[0130] The second handle coupling portion (122) may be formed by cutting a part of the front panel (120). The second protrusion (330) of the handle (300) may be provided to penetrate the front panel (120) through the second handle coupling portion (122).

[0131] Accordingly, the second handle coupling part (122) may be provided with a size corresponding to the diameter of the second protrusion (330) of the handle (300). However, it is not limited thereto, and the diameter of the second handle coupling part (122) may be provided slightly smaller than the diameter of the second protrusion (330) of the handle (300) to increase the coupling force between the handle (300) and the door (100).

[0132] The second handle coupling part (122) is cut so that the second protrusion (330) passes through, and can be formed in an area corresponding to the second contact part (350).

[0133] The second projection passing portion (124) may be formed on the side of the second handle coupling portion (122). The second projection passing portion (124) may be provided so that the second guide projection (135) of the door frame (130) penetrates the front of the front panel (120). Accordingly, the second projection passing portion (124) may be formed at a position corresponding to the second guide projection (135) of the door frame (130).

[0134] The second guide projection (135) can be formed to be biased to one side with respect to the direction in which the handle (300) extends.

[0135] Accordingly, if the handle (300) is incorrectly assembled upside down, the handle (300) may be interfered with by the second guide projection (135) penetrating the front panel (120). Through this, the second guide projection (135) can be provided to prevent incorrect assembly of the handle (300) in the upside-down direction.

[0136] The second handle insertion portion (133) of the door frame (130) provided at the rear of the front panel (120) can be extended rearward to accommodate the second protrusion (330) that passes through the second handle coupling portion (122).

[0137] The second support projection (126) may be provided in an area corresponding to the second contact portion (350) of the handle (300). Specifically, the second support projection (126) may be provided to face the second contact portion (350) of the handle (300) when the handle (300) is coupled to the door (100).

[0138] The second support projection (126) may be provided in a circular shape. However, the shape of the second support projection (126) is not limited thereto.

[0139] The second support projection (126) may be formed on the outer side of the front panel (120) than the second handle coupling part (122). When an external force is applied to the front panel (120), the inner side of the front panel (120) may be partially covered by the handle (300).

[0140] However, the outer side of the front panel (120) is a part that is not covered by the handle (300) and can be easily exposed to the user. Therefore, by forming the second support projection (126) outside the second handle coupling part (122), the effect of making the irregularities of the front panel (120) invisible to the user can be further enhanced.

[0141] However, the position of the second support projection (126) is not limited thereto. Also, in FIG. 5, the second support projection (126) is shown as being formed in two on the upper part of the second handle coupling part (122), but the number of the second support projection (126) is not limited thereto.

[0142] For example, the second support projection (126) may not be provided in multiple numbers but may be provided as a single unit. The second support projection (126) may be formed as a single projection in an area corresponding to the second contact portion (350) of the handle (300).

[0143] Additionally, the area where the second support projection (126) is formed is not limited to that shown in FIG. 5, but can be formed anywhere that faces the second contact portion (350) of the handle (300). Of course, the second support projection (126) may be provided with the same width as the second contact portion (350) of the handle (300).

[0144] The second support projection (126) can be provided to prevent deformation of the front panel (120).

[0145] More specifically, the second support projection (126) may be provided to prevent the formation of irregularities on the front panel (120) by the tightening force of the fastening member (400) when the handle (300) is coupled to the door (100).

[0146] The second support projection (126) can be extended toward the door frame (130) in an area corresponding to the second contact portion (350) of the handle (300).

[0147] The specific structure of this second support projection (126) will be described later.

[0148] FIG. 6 is a cross-sectional view of a cooking appliance according to an embodiment of the present invention. FIG. 7 is an enlarged view of portion A of FIG. 6. FIG. 8 is an enlarged view of portion B of FIG. 6. FIG. 9 is a view showing a fastening member being coupled at the rear of the door of a cooking appliance according to an embodiment of the present invention.

[0149] As illustrated in FIG. 6, the handle (300) can be attached to the front of the door (100). More specifically, the handle (300) can be attached to the front of the door (100) so as to be in contact with the front panel (120) of the door (100).

[0150] The front panel (120) of the door (100) may be provided to cover the front of the door frame (130). The front panel (120), door frame (130), and rear frame (140) of the door (100) may be provided to be open approximately in the center.

[0151] A transparent member (100) may be positioned in the center of the door (100) to block the open portion and allow a user to observe the interior from the outside.

[0152] Hereinafter, with reference to FIGS. 7 and FIGS. 8, the specific structure of the first support projection (125) and the second support projection (126) of a cooking device (1) according to one embodiment of the present invention and their relationship with the counterpart will be explained.

[0153] Referring to FIG. 7, the first support projection (125) can be formed by being recessed from the front panel (120) toward the door frame (130).

[0154] Specifically, the first support projection (125) can be formed by being recessed from the front of the front panel (120) toward the rear.

[0155] The first support projection (125) can be in contact with the front of the door frame (130) so as to maintain a separation between the front panel (120) and the door frame (130).

[0156] The first support projection (125) may include a first connecting part (1251) and a first support part (1252).

[0157] The first connecting part (1251) may be provided as a portion extending from the front panel (120) to the rear of the front panel (120). That is, the first connecting part (1251) may serve to transmit a load.

[0158] The first support member (1252) can be connected to the first connecting member (1251) and arranged to be in surface contact with the front of the door frame (130). That is, the first support member (1252) can serve to support a load.

[0159] Referring to FIG. 8, the second support projection (126) can be formed by being recessed from the front panel (120) toward the door frame (130).

[0160] Specifically, the second support projection (126) can be formed by being recessed from the front of the front panel (120) toward the rear.

[0161] The second support projection (126) can be in contact with the front of the door frame (130) so as to maintain a separation between the front panel (120) and the door frame (130).

[0162] The second support projection (126) may include a second connecting part (1261) and a second support part (1262).

[0163] The second connecting portion (1261) may be provided as a part extending from the front panel (120) to the rear of the front panel (120). That is, the second connecting portion (1261) may serve to transmit a load.

[0164] The second support member (1262) can be connected to the second connecting member (1261) and arranged to be in surface contact with the front of the door frame (130). That is, the second support member (1262) can serve to support a load.

[0165] Referring to FIG. 9, the method of connecting the connecting member (400) to the door (100) will be explained. This is explained using the lower corner side of the door (100) as an example, but since this method of connection can be applied equally to the upper corner side of the door (100), the explanation will be omitted.

[0166] The rear frame (140) may include a coupling hole (141) formed at a position corresponding to the second handle insertion part (133) of the door frame (130) and positioned at the rear of the door frame (130).

[0167] Accordingly, the fastening member (400) can be coupled at the rear of the door (100). Specifically, the fastening member (400) can pass through the coupling hole (141) of the rear frame (140) at the rear of the door (100) and through the second handle insertion part (133) of the door frame (130). Additionally, the fastening member (400) that has passed through the second handle insertion part (133) can be inserted into the second protrusion (330) of the handle (300).

[0168] Through this, the second contact portion (350) of the handle (300) and the front surface of the front panel (120) can be closely attached by the tightening force of the fastening member (400).

[0169] The front panel (120) may be made of stainless steel. More specifically, the front panel (120) may be made of a thin steel plate.

[0170] Therefore, the front panel (120) may be configured to be vulnerable to deformation caused by external forces. Additionally, the front panel (120), which is formed relatively thinly, may show irregularities caused by light reflection more noticeably.

[0171] Additionally, the front panel (120) may be provided in front of the door frame (130) at a certain distance from the door frame (130).

[0172] The front panel (120) and the door frame (130) can be bonded by an adhesive. Since this adhesive is not applied to the entire facing surface between the front panel (120) and the door frame (130), a gap may be formed between the front panel (120) and the door frame (130).

[0173] Accordingly, when the fastening member (400) is fastened from the rear, the front panel (120), which is formed relatively thinly, can be deformed toward the door frame (130) by the tightening force of the fastening member (400).

[0174] However, the first support projection (125) and the second support projection (126) of the cooking device (1) according to one embodiment of the present invention are provided to support an external force by the fastening member (400), thereby preventing the formation of irregularities on the front panel (120).

[0175] Additionally, the front panel (120) may have reduced rigidity at the first handle coupling part (121) and the second handle coupling part (122) where the handle (300) is cut to be coupled.

[0176] Accordingly, by forming the first support projection (125) adjacent to the first handle coupling part (121) and the second support projection (126) adjacent to the second handle coupling part (122), there may also be an effect of reinforcing the rigidity of the front panel (120).

[0177] Additionally, although the first support projection (125) and the second support projection (126) of the cooking device (1) according to one embodiment of the present invention are shown and described as being formed by being recessed in the front panel (120), the method of forming the first support projection (125) and the second support projection (126) may not be limited thereto.

[0178] The first support projection (125) and the second support projection (126) may be formed by a burring method. Additionally, the first support projection (125) and the second support projection (126) may be formed by bending the front panel (120) in a bending method. Furthermore, the second support projection (126) of the first support projection (125) may be compressed through a separate jig. Therefore, the first support projection (125) and the second support projection (126) can be applied in any form as long as they are structured to support the spaced-out space between the front panel (120) and the door frame (130).

[0179] Additionally, although the first support projection (125) and the second support projection (126) were described and illustrated in the above description as being formed on the front panel (120), the first support projection (125) and the second support projection (126) may be provided to protrude from the door frame (130) toward the front panel (120). That is, the first support projection (125) and the second support projection (126) may be configured to minimize deformation of the front panel (120) by maintaining a separation distance between the front panel (120) and the door frame (130), and may be configured to be formed on the door frame (130) by being provided between the front panel (120) and the door frame (130).

[0180] Additionally, the first support projection (125) and the second support projection (126) may be provided as separate components from the front panel (120) and the door frame (130) to maintain a separation between the front panel (120) and the door frame (130).

[0181] Specific embodiments have been illustrated and described above. However, the invention is not limited to the embodiments described above, and those skilled in the art may make various modifications without departing from the essence of the technical concept of the invention as described in the following claims.
