[0036] For convenience of explanation, a dishwasher is described below as one example, but is not limited thereto. It can be applied to all home appliances equipped with a door, including refrigerators, washing machines, ovens, microwave ovens, etc.

[0037] FIG. 1 is a side cross-sectional view of a dishwasher according to one embodiment of the present invention.

[0038] Referring to FIG. 1, the dishwasher (1) may include a housing (10) that forms the exterior. The dishwasher (1) may include a tub (12) provided inside the housing (10). The tub (12) may be provided in a roughly box shape. The front of the tub (12) may be open. That is, the front of the tub (12) may correspond to an opening (12a).

[0039] The dishwasher (1) may include a door (100) provided to open and close the opening (12a) of the tub (12). The upper or lower part of the door (100) may be hinged to the housing (10) to open and close the opening (12a) of the tub (12). It is not limited thereto, but the side of the door (100) may be hinged to the housing (10) to open and close the opening (12a) of the tub (12). Additionally, the door (100) may be installed in the housing (10) by an opening and closing structure other than a hinge.

[0040] The dishwasher (1) may further include a storage container provided inside the tub (12) to store dishes. The storage container may include a plurality of baskets (51, 52, 53).

[0041] Multiple baskets (51, 52, 53) may be arranged in the vertical direction (Z) of the dishwasher (1) and may correspond to the lower basket (51), middle basket (52), and upper basket (53) in order from bottom to top. The lower basket (51) may be provided to be supported by the lower guide rack (13b), and the middle basket (52) may be provided to be supported by the middle guide rack (13a). The upper basket (53) may be formed in the form of a rack assembly to store relatively small dishes. The middle guide rack (13a) and the lower guide rack (13b) may be installed on the side of the tub (12) so as to be slidable in the front-rear direction (X) toward the opening (12a) of the tub (12).

[0042] However, it is not limited to this, and depending on the size of the tub (12), the upper basket (53) may not be included. Therefore, the storage container may include only the middle basket (52) and the lower basket (51).

[0043] The dishwasher (1) may include a sump (300) for storing wash water. The dishwasher (1) may include a wash chamber (C), which is a space formed by the interior of a tub (12).

[0044] The washing chamber (C) is a space where dishes placed in baskets (51, 52, 53) can be washed and dried by washing water. The washing chamber (C) can be defined as an inner space of the tub (12) formed by the sides, rear, and bottom (12b) of the tub (12) and a sump (300) communicating with the bottom. The washing water circulating in the washing chamber (C) can be arranged so that it does not leak out of the washing chamber (C) through an external configuration of the sump (300).

[0045] A dishwasher (1) may include a plurality of arm assemblies (41, 42, 43) arranged to spray washing water toward baskets (51, 52, 53) to wash dishes stored in baskets (51, 52, 53). The arm assemblies (41, 42, 43) are arranged in the vertical direction (Z) of the dishwasher (1) and may correspond to a first arm assembly (41), a second arm assembly (42), and a third arm assembly (43) in order from bottom to top. The first arm assembly (41) may be placed at the bottom of the lower basket (51), the second arm assembly (42) may be placed at the bottom of the middle basket (52), and the third arm assembly (43) may be placed at the top of the upper basket (53).

[0046] However, it is not limited thereto. For example, the second arm assembly (42) may be provided on the upper part of the intermediate basket (52). Additionally, if the upper basket (53) is omitted, the third arm assembly (43) may be provided on the upper part of the intermediate basket (52).

[0047] The first arm assembly (41) can be arranged to be rotatable about a rotation axis (41a), the second arm assembly (42) can be arranged to be rotatable about a rotation axis (42a), and the third arm assembly (43) can be arranged to be rotatable about a rotation axis (43a).

[0048] Unlike the second arm assembly (42) and the third arm assembly (43), the first arm assembly (41) can be fixed to one side of the sump (300) and placed on the lower surface (12b) of the tub (12).

[0049] The dishwasher (1) may include a circulation pump (30) that pumps washing water stored in a sump (300) or washing water flowing into the dishwasher (1) from the outside to arm assemblies (41, 42, 43). The washing water pumped by the circulation pump (30) may be supplied to the first arm assembly (41) through an alternating device (200) connected to the circulation pump (30), or moved upward by a duct (60) to be supplied to the second arm assembly (42) or the third arm assembly (43).

[0050] The alternating device (200) can provide washing water to the first arm assembly (41) through a connector (400) connected to the first arm assembly (41), and can provide washing water to the duct (60) through a flow path (62) connected to the duct (60).

[0051] The dishwasher (1) may include a connector (400) connecting the alternating device (200) and the first arm assembly (41). One end of the connector (400) may be in communication with the alternating device (200), and the other end of the connector (400) may be in communication with the first arm assembly (41). Accordingly, as described above, the washing water pumped through the circulation pump (30) flows into the alternating device (200), and the washing water moved to the connector (400) by the alternating device (200) may be sprayed into the lower basket (51) through the first arm assembly (41).

[0052] However, it is not limited to this, and the circulation pump (30) may be directly connected to the connector (400) so that the washing water pumped from the circulation pump (30) may flow directly into the first arm assembly (41) through the connector (400) without passing through the alternating device (200). In this case, the dishwasher (1) may not include the alternating device (200).

[0053] The dishwasher (1) may include a drain hose (not shown) provided to drain the washing water remaining inside the tub (12). The drain hose is connected to a sump (300) and can drain the washing water stored inside the sump (300) to the outside of the dishwasher (1).

[0054] As described above, the washing water collected in the sump (300) can be purified by a filter (not shown) inside the sump (300) and then circulated back into the washing room (C) by a circulation pump (30).

[0055] In the machine room (L) formed at the bottom of the dishwasher (1), components such as the aforementioned circulation pump (30), alternating device (200), and sump (300) may be arranged.

[0064] The fixed trim (112, 113, 114) may include a lower trim (112), an upper trim (114), and a side trim (113). The fixed trim (112, 113, 114) may be attached to the front panel (111) via an adhesive (not shown). The fixed trim (112, 113, 114) may be attached to the front panel (111) using a PUR (Poly Urethane Reactive) adhesive method. However, the method of fixing the fixed trim (112, 113, 114) is not limited thereto. The door panel (110) may be firmly attached to the door body (130) by the fixed trim (112, 113, 114) and may be attached in such a way that it can be easily separated.

[0065] The lower trim (112) may include a lower trim body (112a), a lower trim projection (112b), a lower trim mounting groove (112c), a lower trim segment (112d), and a lower trim rib (112e). The lower trim (112) may be placed on the lower edge portion of the front panel (111).

[0066] The lower trim body (112a) may be extended in the left-right direction (Y) to be fixed to the lower part of the front panel (111). The lower trim body (112a) may have a roughly rectangular plate shape. The lower trim body (112a) may be fixed to the rear of the front panel (111) with adhesive.

[0067] The lower trim projection (112b) may protrude rearward from the lower trim body (112a). The lower trim projection (112b) may extend in the left-right direction (Y) as with the lower trim body (112a). The lower trim projection (112b) may form a lower trim mounting groove (112c) between itself and the lower trim body (112a). The lower trim projection (112b) may have a shape that extends rearward by a predetermined length from the lower trim body (112a) and then extends approximately in the up-down direction (Z). Thus, the lower trim mounting groove (112c) may be open toward the downward direction.

[0068] A lower trim mounting groove (112c) may be formed between a lower trim projection (112b) and a lower trim body (112a). The lower trim mounting groove (112c) may be provided to accommodate a first coupling projection (131) protruding upward from the lower surface (130b) of the door body (130). The lower trim mounting groove (112c) may be provided to correspond to the size and / or shape of the first coupling projection (131). As the first coupling projection (131) is inserted into the lower trim mounting groove (112c), the lower end of the front panel (111) may be fixed to the door body (130). Additionally, the lower end of the front panel (111) mounted on the door body (130) may be supported by the lower surface (130b) of the door body (130) by contacting the lower surface (130b) of the door body (130).

The parts of the lower trim projection (112b) separated by the lower trim segment (112d) may be spaced apart from each other along the direction in which the lower trim projection (112b) extends. As the lower trim segment (112d) separates the lower trim projection (112b) into multiple parts, it is possible to prevent the lower trim (112) from being damaged by the deformation force applied to the lower trim (112) when the front panel (111) is deformed by heat.

[0070] A support rib (133) formed at the bottom of the door body (130) may be inserted into the lower trim segment (112d). The support rib (133) may be provided to extend approximately vertically from the lower surface (130b) of the door body (130). The thickness of the support rib (133) may be equal to or smaller than the width of the lower trim segment (112d), and the position of the support rib (133) may correspond to the position of the lower trim segment (112d). Accordingly, when the door panel (110) is mounted on the door body (130), the support rib (133) may be inserted into the lower trim segment (112d), and the lower trim segment (112d) combined with the support rib (133) may be guided to move along the extension direction of the support rib (133) while the support rib (133) is inserted.

[0071] The lower trim rib (112e) may be formed to protrude towards the rear from the lower trim body (112a). The lower trim rib (112e) may be positioned on the upper part of the lower trim projection (112b). The lower trim rib (112e) may be provided in multiple numbers.

[0072] The lower trim rib (112e) may extend in the left-right direction (Y) as the lower trim body (112a). Specifically, the lower trim rib (112e) may have the same length in the left-right direction (Y) as the lower trim body (112a). However, it is not limited to this, and the lower trim rib (112e) may have a different length in the left-right direction (Y) than the length to which the lower trim body (112a) extends in the left-right direction (Y).

[0073] The lower trim rib (112e) can be inserted into and supported by the support groove (133a) formed in the support rib (133) of the door body (130). Thus, the front panel (111) can be firmly supported by the support rib (133), and the front panel can be prevented from being deformed by external impact.

[0074] The upper trim (114) and the side trim (113) may have the same shape. The following description relates to the side trim (113) and the connecting trim (132) corresponding to the side trim (113), but this description differs only in the extension direction (Y) of the upper trim (114) and can be applied almost identically to the upper trim (114) and the connecting trim (not shown) corresponding to the upper trim (114).

[0075] The side trim (113) may include a side trim body (113a), a side trim projection (113b), and a side trim segment (113c). The side trim (113) may include a plurality of side trims (113) and may be placed on the left and right edges of the front panel (111). The side trim (113) placed on the left edge of the front panel (111) and the side trim (113) placed on the right edge of the front panel (111) may be arranged symmetrically.

[0076] The side trim body (113a) is fixed to the left and right ends of the front panel (111), respectively, and can extend approximately in the vertical direction (Z). The side trim body (113a) may have a plate shape that is approximately rectangular. The side trim body (113a) can be fixed to the rear of the front panel (111) using adhesive.

[0077] The side trim projection (113b) may protrude rearward from the side trim body (113a). The side trim projection (113b) may extend in the vertical direction (Z) as the side trim body (113a). The side trim projection (113b) may be formed to be coupled to a coupling trim (132) provided on the door body (130). Specifically, the side trim projection (113b) may be inserted into and supported in a coupling trim mounting groove (132d) formed in the coupling trim (132), and accordingly, the side trim (113) may be fixed to the coupling trim (132).

[0078] The side trim projection (113b) may be composed of a material having a certain elasticity so that it can be deformed and restored as it is pressed by the coupling trim (132) when coupled to the coupling trim (132). When the front panel (111) is mounted to the door body (130), the side trim projection (113b) may be provided to generate an elastic force in the direction of contact with the coupling trim (132). The coupling process between the side trim (113) and the coupling trim (132) will be described in detail later.

[0079] A side trim segment (113c) may be formed on a side trim projection (113b). The side trim segment (113c) may be provided to separate the side trim projection (113b) into multiple parts. The parts of the side trim projection (113b) separated by the side trim segment (113c) may be spaced apart from each other along the direction in which the side trim projection (113b) extends. The side trim segment (113c) may include multiple side trim segments (113c). As the side trim segment (113c) separates the side trim projection (113b) into multiple parts, it is possible to prevent the side trim (113) from being damaged by the deformation force applied to the side trim (113) when the front panel (111) is deformed by heat.

[0080] The door body (130) can form the outer surface of the door (100). Specifically, when the door panel (110) is positioned in front of the door body (130), the door body (130) forms the side surfaces (100a) and bottom surface of the door (100), and the door panel (110) and upper frame (140) can be mounted.

[0081] The above-described support rib (133) and first coupling projection (131) may be formed at the bottom of the door body (130). The support rib (133) and the first coupling projection (131) may protrude upward from the lower surface (130b) of the door body (130). The support rib (133) and the first coupling projection (131) may be formed integrally. The door body (130) may include the support rib (133) and the first coupling projection (131). However, it is not limited thereto, and the support rib (133) and the first coupling projection (131) may be provided as separate parts that can be separated from the door body (130).

[0082] The door body (130) may include a fastening recess (134) into which a fixer (116), described later, is inserted, formed by recessing a portion of the front of the door body (130). The fastening recess (134) may include an opening (134a) that opens toward the front, and the fixer (116) may be inserted through the opening (134a). Since the fixer (116) is positioned on the top of the front panel (111), the fastening recess (134) may be formed on the top of the door body (130) to correspond to the fixer (116).

[0083] A fastening hole (134b) communicating with the outside of the door (100) may be formed on one side of a fastening recess (134) near the side wall (130a) of the door body (130) so that a fastening member (150) can pass through. Specifically, the door body (130) may include an insertion recess (135) formed by recessing the side of the door body (130). One side of the insertion recess (135) may be connected to the side (100a) of the door (100) to communicate with the outside of the door (100), and the other side may be connected to the fastening hole (134b). The fastening hole (134b) may be connected to the outside of the door (100) through the insertion recess (135). Since one side of the fastening hole (134b) is connected to the insertion recess (135) and the other side is connected to the fastening recess (134), the fastening recess (134) can be connected to the outside of the door body (130) through the fastening hole (134a) and the insertion recess (135).

[0084] However, it is not limited to this. The insertion recess (135) may be omitted or may be integral with the fastening hole (134a). In this case, one side of the fastening hole (134a) may be directly connected to the side (100a) of the door (100) and the other side may be connected to the fastening recess (134).

[0085] The door (100) may include a cap (151) that is inserted into an insertion recess (135). The cap (151) may be inserted into the insertion recess (135) and coupled, and may form a part of the side (100a) of the door (100) while covering a fastening member (150) that is inserted into the insertion recess (135) and passes through a fastening hole (134a).

[0086] The door (100) may include a connecting trim (132) provided on the front of the door body (130). The connecting trim (132) may include a plurality of connecting trims (132). The connecting trim (132) may be provided at a position corresponding to the side trim (113). The connecting trim (132) may extend in the same direction and length as the corresponding side trim (113).

[0087] The combined trim (132) may include a combined trim body (132a), a reinforcing flange (132b) protruding forward from one end of the combined trim body (132a), and a combined flange (132c) protruding forward from the other end of the combined trim body (132a).

[0088] The combined trim body (132a) may have a roughly rectangular plate shape and may be fixed to the front of the door body (130). Specifically, the door body (130) is provided to correspond to the side trim (113) and may include a trim fixing groove (136) extending in the vertical direction (Z) on the front left and right edges of the door body (130). The combined trim body (132a) may be inserted into the trim fixing groove (136), and the combined trim body (132a) may be fixed while inserted into the trim fixing groove (136) of the door body (130) by means of adhesive or screws. The combined trim (132) positioned on the left edge of the door body (130) and the combined trim (132) positioned on the right edge of the door body (130) may be provided symmetrically to each other.

[0089] When the combined trim body (132a) is fixed by a screw, the combined trim body (132a) may be provided with a plurality of connecting holes (132aa), and the screw may pass through the connecting holes (132aa) and be fastened to the door body (130).

[0090] The reinforcing flange (132b) may be formed to protrude forward from one end of the combined trim body (132a) that is closer to the outside of the door (100), and may support the side wall (130a) of the door body (130). The outer surface of the side wall (130a) of the door body (130) may form the side of the door body (130) corresponding to the side (100a) of the door (100). Specifically, one side of the trim fixing groove (136) into which the combined trim (132) is inserted and fixed may be formed by the inner surface of the side wall (130a) of the door body (130), and the reinforcing flange (132b) protruding from the combined trim body (132a) inserted into the trim fixing groove (136) may contact the inner surface of the side wall (130a) of the door body (130) to support the side wall (130a) of the door body (130). Through this, the reinforcement plan (132b) can prevent the side (100a) of the door (100) from being deformed by an impact applied to the side (100a) of the door (100).

[0091] The coupling flange (132c) may include a guide portion (132ca) that induces elastic deformation of the side trim projection (113b) and a support portion (132cb) that supports the side trim projection (113b) coupled to the coupling trim (132).

[0092] The guide portion (132ca) may be exposed to the outside in the front direction of the door body (130) and may include a guide slope surface (132cc) that is inclined in a direction that moves further away from the front panel (111) as it moves away from the center of the door body (130). The guide slope surface (132cc) may come into contact with the side trim projection (113b).

[0093] The support member (132cb) may be bent and extended from one end of the guide member (132ca) located furthest from the front panel (111), and may include a support inclined surface (132cd) that is inclined in a direction that moves further away from the front panel (111) as it approaches the center of the door body (130). The support inclined surface (132cd) may come into contact with the side trim projection (113b). The guide member (132ca) and the support member (132cb) may be formed integrally.

[0094] The coupling trim (132) may include a coupling trim body (132a), a reinforcing flange (132b), and a coupling trim mounting groove (132d) formed by a coupling flange (132c), and the side trim projection (113b) may be fixed to the coupling trim (132) by being inserted into the coupling trim mounting groove (132d) formed by the coupling trim (132).

[0095] Meanwhile, since the side trim (113) is fixed to the rear of the front panel (111), when the door panel (110) is mounted on the door body (130), the side trim projection (113b) can be inserted into the corresponding coupling trim mounting groove (132d) and coupled. The side trim projection (113b) may include a pressure portion (113ba) that is pressed in the direction of the side wall (130a) of the door body (130) by a guide portion (132ca), a contact portion (113bb) that is connected to the pressure portion (113ba) and is supported by contacting a support portion (132cb), and an elastic deformation portion (113bc) that connects the contact portion (113bb) to the side trim body (113a) and is elastically deformed as the pressure portion (113ba) is pressed. The contact portion (113bb) may extend at one end of the elastic deformation portion (113bc) protruding vertically from the side trim body (113a) at an angle approximately equal to the angle of the support slope surface (132cd), and the pressure portion (113ba) may be bent and extended from one end of the contact portion (113bb) and extend at an angle approximately equal to the angle of the guide slope surface (132cc).

[0096] However, it is not limited to this, and the guide portion (132ca) in the coupling trim (132) may be omitted. In this case, the pressing portion (113ba) of the side trim projection (113b) may be pressed by one end of the support portion (132cb). Additionally, the coupling trim (132) may be formed integrally with the door body (130). For example, the coupling trim (132) corresponding to the upper trim (114) of the door (100) shown in the drawing may be formed integrally with the door body (130) and may be in a form in which the guide portion (132ca) is omitted.

[0097] The door (100) may include a fixer (116) positioned at the rear of the front panel (111) to secure the front panel (111) to the door body (130). The fixer (116) may include a plurality of fixers (116). The fixer (116) may be positioned at the top of the front panel (111) and may be secured to the rear of the front panel (111) through adhesive.

[0098] The fixer (116) may include a plate portion (116a) fixed to the rear of the front panel (111), a body portion (116b) protruding from the plate portion (116a) toward the rear of the front panel (111), and a fastening portion (116c) formed on the side of the body portion (116b).

[0099] The body portion (116a) of the fixer (116) can be inserted into a corresponding fastening recess (134). When the body portion (116a) of the fixer (116) is inserted into the fastening recess (134), the fastening portion (116c) can be positioned to correspond to a fastening hole (134b) formed on one side of the fastening recess (134). That is, the fastening portion (116c) can be positioned to face the fastening hole (134b).

[0100] The fastening member (150) can penetrate the side of the door body (130), the insertion recess (135), and the fastening hole (134b) in a direction perpendicular to the side (100a) of the door (100), and can be fastened to the side of the fixer (116) inserted into the fastening recess (134) in a direction perpendicular to the direction in which the fastening member (150) penetrates the fastening hole (134b). Specifically, the fastening member (150) can be detachably fastened to the fastening portion (116c) formed in the body portion (116b) of the fixer (116) inserted into the fastening recess (134).

[0101] The fastening member (150) may include a positioning member such as a screw or a pin. In this way, the door panel (110) can be firmly mounted to the door body (130) by means of the fastening member (150) and the fixer (116) fixed to the front panel (111).

[0102] Additionally, when the door (100) is rotated so that its front face is facing downward and opened, if sufficient fixing force is not provided to the door panel (110) forming the front of the door (100), the door panel (110) may be unintentionally separated from the door body (130) by gravity. Accordingly, the fixer (116) and the fastening member (150) can provide sufficient fixing force to the door panel (110) to prevent the door panel (110) from being unintentionally separated from the door body (130) by gravity.

[0103] FIG. 13 is a disassembled view of the door body and upper frame of the door shown in FIG. 2. FIG. 14 and FIG. 15 are enlarged views of area C of FIG. 13. FIG. 16 is an enlarged view of area D of FIG. 13. FIG. 17 is an enlarged view of area D of FIG. 13 when the door body and upper frame of FIG. 13 are combined.

[0104] Referring to FIGS. 13 to 15, the door (100) may include an upper frame (140) mounted on the upper part of the door body (130) to form part of the upper surface of the door (100) and the side (100a) of the door (100).

[0105] The upper frame (140) may include a control panel (not shown) for controlling the operation of the dishwasher (1). Specifically, the control panel may be positioned on the upper part of the upper frame (140) so as to be provided on the upper surface of the door (100). Additionally, the upper frame (140) may include a handle (141) of the door (100).

[0106] The upper frame (140) may include a frame portion (142) forming an exterior and a handle (141), a coupling portion (144) through which a fastening member (not shown) protrudes from the lower part of the frame portion (142) and is fixed to the door body (130) passes, and a fixing portion (143) protruding from the lower part of the frame portion (142) and supported by a coupling guide (160).

[0107] Meanwhile, the door (100) may include a coupling guide (160) that supports the fixing part (143) of the upper frame (140) and guides the movement of the fixing part (143). The coupling guide (160) may extend in the front-rear direction (X). The coupling guide (160) may be positioned on the upper sides of the door body (130) so as to correspond to the fixing part (143) of the upper frame (140). The coupling guide (160) may form a guide mounting groove (160c) into which a part of the fixing part (143) is inserted and which extends in the front-rear direction (X).

[0108] The coupling guide (160) may be formed protruding from the inner surface of the side wall (130a) of the door body (130). The coupling guide (160) may be formed integrally with the door body (130). However, it is not limited thereto, and the coupling guide (160) may be provided as a separate part and coupled to the door body (130), or may be provided at another location corresponding to the fixing part (143) of the upper frame (140).

[0109] The upper frame (140) may include a second coupling projection (145) that is formed on one side of the fixed part (143), can be inserted into a guide mounting groove (160c) formed by a coupling guide (160), and can be guided to move. Specifically, the coupling guide (160) may include a first extension part (160a) protruding from the side wall (130a) of the door body (130), and a second extension part (160b) that is bent downward and extended from the end of the first extension part (160a). The upper surface (145a) of the second coupling projection (145) may be supported by the first extension part (160a), and the side surface (145b) of the second coupling projection (145) that forms part of the inner surface of the fixed part (143) may be supported by the second extension part (160b).

[0110] However, it is not limited thereto. For example, the coupling guide (160) may include a third extension that is spaced apart from the second extension (160b) and extends downward from the first extension (160a), and the guide mounting groove (160c) may be provided between the second extension (160b) and the third extension, and the side of the second coupling projection (145) forming part of the outer surface of the fixing part (143) may be supported by the third extension.

[0111] The connecting part (144) may be formed to protrude downward from the lower surface of the frame part (142), may be inserted into the connecting part insertion groove (137) formed on the upper surface of the door body (130), and may be connected to the rear surface of the door body (130) by a fastening member (not shown).

[0112] However, it is not limited to this, and the upper frame (140) may be mounted on the lower part of the door body (130) to form the lower surface of the door (100). In this case, the frame part (142), the coupling part (144), the fixing part (143), the second coupling projection (145), and the coupling guide (160), etc., may each have a configuration that is approximately the same with respect to a horizontal plane parallel to the upper and lower surfaces of the door (100) compared to the case where the upper frame (140) is mounted on the upper part of the door body (130).

[0113] FIG. 18 is a drawing showing the lower trim shown in FIG. 7 being joined to the door body. FIG. 19 is a drawing showing the side trim shown in FIG. 10 being joined to the joining trim.

[0114] Referring to FIGS. 4, FIGS. 7, FIGS. 10, FIGS. 13, FIGS. 16 to 19, the process of assembling the door panel (110) and the upper frame (140) to the door body (130) is described in detail.

[0115] First, the assembly process of the door panel (110) is described. The door panel (110), which is separated from the door body (130), can be prepared with a lower trim (112), a side trim (113), an upper trim (114), a cushioning member (115), and a fixer (116) attached to the rear of the front panel (111).

[0116] The door panel (110) can be aligned so that the lower trim (112) faces the first coupling projection (131) of the door body (130). The door panel (110) is rotated so that the first coupling projection (131) can be inserted into the lower trim mounting groove (112c) while the end of the first coupling projection (131) is aligned so that it is positioned at the entrance of the lower trim mounting groove (112c). With reference to FIG. 18, the door panel (110) is rotated clockwise so that the lower end of the door panel (110) can be primarily mounted to the door body (130) as shown in FIG. 7. At this time, the lower trim rib (112e) can be inserted into the support groove (133a) formed in the support rib (133) of the door body (130).

[0117] As the door panel (110) is rotated to be coupled to the door body (130), the side trim (113) can be coupled to the coupling trim (132). The side trim (113) can be coupled to the coupling trim (132) sequentially from the bottom to the top.

[0118] Specifically, when the pressure portion (113ba) corresponding to one end of the side trim (113) comes into contact with the guide portion (132ca) of the coupling trim (132), the pressure portion (113ba) of the side trim projection (113b) is pressed while in contact with the guide inclined surface (113cc), and the side trim projection (113b) can be elastically deformed so as to tilt toward the side of the door (100) compared to before being pressed.

[0119] In that state, as the door panel (110) and the door body (130) get closer, the pressure member (113ba) moves toward the rear of the door (100) along the guide inclined surface (113cc), that is, the pressure member (113ba) can be guided by the guide inclined surface (113cc) to move toward the entrance of the coupling trim mounting groove (132d). When one end of the pressure member (113ba) on the contact part (113bb) side reaches the end of the guide inclined surface (132cc), the pressure exerted by the guide inclined surface (132cc) disappears, so the pressure member (113ba) can be elastically restored to its position before being pressured. Since the end of the guide inclined surface (132cc) forms the entrance of the coupling trim mounting groove (132d), the pressurizing part (113ba) that reaches the end of the guide inclined surface (132cc) can be inserted into the coupling trim mounting groove (132d).

[0120] Accordingly, when the pressure portion (113ba), which is inserted into the coupling trim mounting groove (132d), is restored to its original position before being pressured, the contact portion (132bb) can come into contact with the support portion (132cb) located at the rear of the guide portion (132ca), and the contact portion (113bb) can be supported by the support inclined surface (132cd) so that the side trim (113) is not easily separated forward.

[0121] When the connection of the side trim (113) is completed, the upper trim (114) can be connected to the corresponding connecting trim (132). Since this is similar to the connection of the side trim (113), a detailed explanation is omitted.

[0122] When the side trim (113) is assembled, the fixer (116) can be inserted into the corresponding fastening recess (134). A fastening member (150) inserted into the door body (130) through the side of the door body (130) can be coupled to the fixer (116) inserted into the fastening recess (134). As the fastening member (150) is coupled to the fixer (116), the front panel (111) can be firmly fixed to the door body (130) via the fixer (116). A cap (151) can be coupled to the insertion recess (135).

[0123] In this way, when the combination of the lower trim (112), the side trim (113), the upper trim (114), and the fixer (116) is completed, the combination between the door panel (110) and the door body (130) can be completed.

[0124] By reversing the process described above, the door panel (110) can be separated from the door body (130).

[0125] The assembly process of the upper frame (140) is described. The upper frame (140), which is separated from the door body (130), can be aligned such that the fixing part (143) is positioned behind the coupling guide (160) and the coupling part (144) is positioned behind the coupling part insertion groove (137).

[0126] The upper frame (140) can be slid so that the second coupling projection (145) can be inserted into the guide mounting groove (160c) while aligned such that the end of the second coupling projection (145) is positioned at the entrance of the guide mounting groove (160c) formed by the coupling guide (160). Specifically, with reference to FIGS. 13 and FIGS. 17, the upper frame (140) is pushed forward from the rear of the door (100) and mounted, and when the upper frame (140) is pushed, the second coupling projection (145) of the fixing part (143) is inserted into the guide mounting groove (160c) and moves. The coupling guide (160) can guide the movement of the second coupling projection (145) and support the second coupling projection (145) inserted into the guide mounting groove (160c).

[0127] As the second coupling projection (145) is inserted into the coupling guide (160), the coupling portion (144) can also be inserted into the coupling portion insertion groove (137). When the insertion of the second coupling projection (145) and the coupling portion (144) is completed, the lower surface of the frame portion (142) of the upper frame (140) can come into contact with the upper surface of the door body (130) so as to face each other. Once the insertion of the coupling portion (144) is finished, the upper frame (140) can be fixed to the door body (130) by fastening a fastening member (not shown) to the coupling portion (144) and the door body (130). Through this process, the upper frame (140) can be mounted to the door body (130), and by proceeding in reverse of the above-described process, the upper frame (140) can be separated from the door body (130).

[0128] In this way, since the position and movement of the upper frame (140) are guided by the coupling guide (160), an error in the coupling position can be prevented when coupling the upper frame (140), and a step difference can be prevented on the side (100a) of the door (100) formed by the door body (130) and the upper frame (140).

[0129] Additionally, the fastening member (150) coupled to the fixer (116) penetrates the side of the door body (130) rather than the upper surface and is coupled to the fixer (116), so it may not be subject to interference from the upper frame (140) positioned on the upper part of the door body (130). Therefore, the mounting of the door panel (110) and the mounting of the upper frame (140) may not be affected by the mounting order, and the operation of fastening the fastening member (150) to the fixer (116) can be performed with sufficient workspace secured without interference from the upper frame (140), and the user can freely mount or detach the door panel (110) to the door body (130) without the operation of detaching the upper frame (140).

[0130] 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.
