[0076] Hereinafter, embodiments according to the present disclosure will be described in detail with reference to the accompanying drawings.

[0077] Figure 1 is a perspective view illustrating an example of a refrigerator according to an embodiment. Figure 2 is a side cross-sectional view illustrating an example of a refrigerator according to an embodiment.

[0078] refer to Figure 1 and Figure 2 , the refrigerator 1 will be described as an example of a home appliance including the plate assembly 80a. However, the home appliance according to the present disclosure is not limited to the refrigerator 1. For example, the plate assembly 80a may be applied to various home appliances such as a washing machine, a clothing care device, a shoe care device, an air conditioner, an air purifier, a humidifier, a cooking appliance, a dishwasher, a television (TV), etc.

[0079] refer to Figure 1 and Figure 2, the refrigerator 1 may include a body 10. The refrigerator 1 may include a storage chamber 20 disposed inside the body 10. The refrigerator 1 may include a door 30 configured to open and close the storage chamber 20. The refrigerator 1 may include a cooling system configured to supply cool air to the storage chamber 20.

[0080] The main body 10 may form at least a portion of the outer appearance of the refrigerator 1. The main body 10 may have a front side with an opening to allow a user to put food into or take food out of the storage chamber 20. The main body 10 may include an opening 10a. The opening 10a of the main body 10 may be opened and closed by a door 30.

[0081] The door 30 may be provided to open and close the main body 10. The door 30 may be configured to open and close the opening 10a of the main body 10. The door 30 may be rotatably coupled to the main body 10. For example, the door 30 may be rotatably coupled to the main body 10 by a hinge 40 connected to the door 30 and the main body 10.

[0082] The outer surface 31 of the door 30 may form a portion of the outer appearance of the refrigerator 1. The outer surface 31 of the door 30 may form a front surface of the door 30 when the door 30 is in a closed position.

[0083] The inner surface 32 of the door 30 may be formed on a side opposite to the outer surface 31 of the door 30. When the door 30 is in the closed position, the inner surface 32 of the door 30 may form a rear surface of the door 30. When the door 30 is in the closed position, the inner surface 32 of the door 30 may be disposed to face the interior of the body 10. When the door 30 is in the closed position, the inner surface 32 of the door 30 may be disposed to cover the front of the storage chamber 20.

[0084] The door 30 may include a door insulator 35. The door insulator 35 may be disposed between an outer surface 31 of the door 30 and an inner surface 32 of the door 30. For example, a foaming space may be formed between the outer surface 31 of the door 30 and the inner surface 32 of the door 30, and the door insulator 35 may be foamed in the foaming space. The door insulator 35 may prevent heat exchange from occurring between the outer surface 31 of the door 30 and the inner surface 32 of the door 30. The door insulator 35 may improve thermal insulation performance between the interior of the storage chamber 20 and the exterior of the door 30.

[0085] For the door insulator 35 , polyurethane foam insulator, expanded polystyrene insulation (EPS), vacuum insulation panel, etc. may be used. However, the present disclosure is not limited thereto, and the door insulator 35 may include various other materials for improving insulation performance between the storage chamber 20 and the door 30 .

[0086] For example, the door insulator 35 may be configured by an insulator formed of the same material as a body insulator 55 to be described below. On the other hand, for example, the door insulator 35 may be configured by an insulator formed of a material different from that of the body insulator 55.

[0087] The door 30 may include a door gasket 33. The door gasket 33 may be disposed on the inner surface 32 of the door 30. The door gasket 33 may seal the gap between the door 30 and the main body 10 to prevent cold air from leaking from the storage chamber 20. The door gasket 33 may be disposed along the periphery of the inner surface 32 of the door 30. The door gasket 33 may be arranged to be parallel to the opening 10a of the main body 10 when the door 30 is closed. The door gasket 33 may be configured to include an elastic material such as rubber. However, it is not limited thereto, and the door gasket 33 may include various materials for sealing between the door 30 and the main body 10.

[0088] The door 30 may include a door basket 34 for storing food. The door basket 34 may be provided on the inner surface 32 of the door 30.

[0089] The door 30 may be configured to open and close the inner space of the main body 10 as a whole. The door 30 may be configured to open and close the storage chamber 20 provided inside the main body 10. The door 30 may be configured to open and close the first storage chamber 21 and the second storage chamber 22 to be described below. That is, the first storage chamber 21 and the second storage chamber 22 may be opened and closed by a single door 30, without providing a door for opening and closing the first storage chamber 21 and a door for opening and closing the second storage chamber 22.

[0090] For example, when the opening 10a of the body 10 is closed, the door 30 may close the first storage chamber 21 to be described below. When the opening 10a of the body 10 is closed, the door 30 may cover the front of the first storage chamber 21.

[0091] For example, when the opening 10a of the body 10 is closed, the door 30 may close the second storage chamber 22 to be described below. When the opening 10a of the body 10 is closed, the door 30 may cover the front of the second storage chamber 22.

[0092] For example, when the opening 10a of the body 10 is closed, the door 30 may cover the front of the first drawer 25 to be described below. In a state where the first drawer 25 is inserted into the first lower storage chamber 21b, the front of the first drawer 25 may be covered by the door 30. However, it is not limited thereto, and the door 30 may directly close the first lower storage chamber 21b.

[0093] For example, when the opening 10a of the body 10 is closed, the door 30 may cover the front of the second drawer 26 to be described below. In a state where the second drawer 26 is inserted into the second storage chamber 22, the front of the second drawer 26 may be covered by the door 30. However, it is not limited thereto, and the door 30 may directly close the second storage chamber 22.

[0094] For example, when the opening 10a of the body 10 is closed, the door 30 may cover the front of the first shelf 23. The entire first shelf 23 may be arranged inside the body 10, and thus in a state where the opening 10a of the body 10 is closed, the first shelf 23 may be covered by the door 30 and not visible from the outside.

[0095] For example, when the opening 10a of the body 10 is closed, the door 30 may cover the front of the second shelf 24. The entire second shelf 24 may be disposed inside the body 10, and thus, in a state where the opening 10a of the body 10 is closed, the second shelf 24 may be covered by the door 30 and not visible from the outside.

[0096] The main body 10 may include an outer shell 50. The outer shell 50 may form at least a portion of the outer appearance of the refrigerator 1. The outer shell 50 may be disposed outside the inner shell 60. The outer shell 50 may be formed to have a substantially box-like shape with a front surface having an opening. For example, the outer shell 50 may form the upper and lower surfaces, the left and right surfaces, and the rear surface of the refrigerator 1.

[0097] The outer shell 50 may include a metal material. For example, the outer shell 50 may be manufactured by processing a steel plate material.

[0098] The main body 10 may include an inner shell 60. The inner shell 60 may be disposed inside the outer shell 50. The inner shell 60 may form a storage chamber 20. The inner space of the inner shell 60 may be provided as the storage chamber 20. The inner shell 60 may have a shape with an open front. The inner shell 60 may be formed to have a substantially box-like shape with an open front surface.

[0099] The inner housing 60 may include inner walls 61 , 62 , 63 , 64 , and 65 .

[0100] For example, the inner case 60 may include a right wall 61, an upper wall 62, a left wall 63, a bottom wall 64, and a rear wall 65. For example, the right wall 61, the upper wall 62, the left wall 63, the bottom wall 64, and the rear wall 65 of the inner case 60 may form the storage chamber 20.

[0101] The inner housing 60 may include a plastic material. For example, the inner housing 60 may be manufactured by a vacuum forming process. For example, the inner housing 60 may be manufactured by an injection molding process.

[0102] The main body 10 may include a main body insulator 55. The main body insulator 55 may be disposed between the outer shell 10 and the inner shell 60. The main body insulator 55 may be configured to insulate the outer shell 50 and the inner shell 60 from each other. As the main body insulator 55 is foamed between the outer shell 50 and the inner shell 60, the outer shell 50 and the inner shell 60 may be coupled to each other. The main body insulator 55 may prevent heat exchange between the inside of the storage chamber 20 and the outside of the main body 10, thereby improving the cooling efficiency of the storage chamber 20.

[0103] Polyurethane foam insulation, expanded polystyrene insulation (EPS), vacuum insulation panels, etc. may be used for the body insulator 55. However, the present disclosure is not limited thereto, and the body insulator 55 may be configured to include various other materials.

[0104] The body 10 may include a storage chamber 20. The storage chamber 20 may be formed by an inner shell 60. The storage chamber 20 may be provided as a space inside the inner shell 60. The storage chamber 20 may be provided as a single unit. For example, the inner shell 60 may have a box shape, have a front with an opening, and include the storage chamber 20 formed therein.

[0105] The storage chamber 20 may be divided into a plurality of spaces by the partition 70. For example, the storage chamber 20 may be divided into a first storage chamber 21 and a second storage chamber 22 by the partition 70.

[0106] The body 10 may include a first storage chamber 21 and a second storage chamber 22. The first storage chamber 21 may be disposed above the second storage chamber 22. The first storage chamber 21 may be disposed above the second storage chamber 22 (in the +Z direction). The second storage chamber 22 may be disposed below the first storage chamber 21. The second storage chamber 22 may be disposed below the first storage chamber 21 (in the -Z direction).

[0107] The first storage chamber 21 and the second storage chamber 22 may have different temperatures. However, it is not limited thereto, and the first storage chamber 21 and the second storage chamber 22 may be set to have the same temperature as desired.

[0108] For example, the first storage chamber 21 may include a first upper storage chamber 21a and a first lower storage chamber 21b. The first upper storage chamber 21a may be disposed above the first lower storage chamber 21b. The first upper storage chamber 21a may be disposed above the first lower storage chamber 21b (in the +Z direction). The first lower storage chamber 21b may be disposed below the first upper storage chamber 21a. The first lower storage chamber 21b may be disposed below the first upper storage chamber 21a (in the -Z direction).

[0109] For example, a first shelf 23 on which food can be placed, a storage container (not shown) in which food can be stored, etc. may be provided in the first upper storage chamber 21a. At least one first shelf 23 may be provided. At least one storage container may be provided.

[0110] For example, the first drawer 25 may be disposed in the first lower storage chamber 21b. The first drawer 25 may be configured to be drawn out of and inserted into the first lower storage chamber 21b through the opening 10a of the main body 10. The first drawer 25 may be configured to be drawn out and inserted in the front-rear direction (X direction). For example, the second shelf 24 may be disposed above the first drawer 25 (+Z direction). Food may be placed on the second shelf 24. For example, the first lower storage chamber 21b may be defined by the first drawer 25 and the second shelf 24.

[0111] Unlike the first upper storage chamber 21a, the first lower storage chamber 21b can be prevented from contacting the outside air even when the door 30 is opened relative to the body 10. Therefore, compared with the first upper storage chamber 21a, the first lower storage chamber 21b can be a space for food that needs to be stored for a relatively long time.

[0112] For example, the second drawer 26 may be disposed in the second storage chamber 22. The second drawer 26 may be configured to be drawn out of or inserted into the second storage chamber 22 through the opening 10a of the main body 10. The second drawer 26 may be configured to be drawn out and inserted in the front-rear direction (X direction). For example, the partition 70 may be disposed above the second drawer 26 (+Z direction). For example, the second storage chamber 22 may be defined by the second drawer 26 and the partition 70. However, the size of the second storage chamber 22 may vary depending on the position of the partition 70.

[0113] Meanwhile, the first storage chamber 21 may be configured as a refrigerating chamber 21, and the second storage chamber 22 may be configured as a freezing chamber 22. In this case, the ice maker 27 may be arranged inside the second storage chamber 22. However, this is merely exemplary, and the first storage chamber 21 may be configured as a freezing chamber, and the second storage chamber 22 may be configured as a refrigerating chamber. In this case, the ice maker 27 may be arranged inside the first storage chamber 21.

[0114] Hereinafter, for convenience of description, a case in which the first storage chamber 21 is provided as the refrigerating chamber 21 and the second storage chamber 22 is provided as the freezing chamber 22 will be described as an example.

[0115] The refrigerating chamber 21 may be provided to keep food refrigerated. The refrigerating chamber 21 may be maintained at an appropriate temperature for refrigerated storage.

[0116] The freezer compartment 22 may be configured to keep food frozen. The freezer compartment 22 may be maintained at an appropriate temperature for frozen storage.

[0117] The refrigerator 1 may include a partition 70. The partition 70 may be disposed in the storage chamber 20. The partition 70 may divide the storage chamber 20 into a plurality of spaces. The partition 70 may divide the storage chamber 20 into a refrigerating chamber 21 and a freezing chamber 22.

[0118] The partition 70 may be arranged in front of the cold air duct 80. The partition 70 may be detachably mounted on the cold air duct 80. For example, the partition 70 may be detachably coupled to the front surface of the cold air duct 80.

However, it is not limited thereto, and the cooling chamber 20b and the machine chamber 15 may be arranged in various forms, and the components constituting the cooling system may be arranged in various forms corresponding to the positions of the cooling chamber 20b and the machine chamber 15.

[0124] Since the cold air is generated by the evaporator 12 in the cooling chamber 20b, the cooling chamber 20b can be maintained at a relatively low temperature. Alternatively, since heat is generated by the compressor 11 and the condenser in the machine room 15, the machine room 15 may be maintained at a relatively high temperature. Therefore, the cooling chamber 20b and the machine room 15 may be formed in respective spaces separated from each other for thermal isolation. For example, the main body insulation 55 may be foamed and formed between the cooling chamber 20b and the machine room 15.

[0125] The evaporator 12 provided in the cooling chamber 20b can generate cold air by evaporating the refrigerant, and the cold air generated by the evaporator 12 can be caused to flow by the fan 13.

The cold air duct 80 may be configured to guide the cold air generated by the evaporator 12 into the storage chamber 20. The cold air duct 80 may be configured to supply the cold air generated by the evaporator 12 to the refrigerating chamber 21 and the freezing chamber 22.

[0130] The refrigerator 1 may include a plate assembly 80a. For example, the cold air duct 80 of the refrigerator 1 may include the plate assembly 80a. However, this is merely exemplary, and the plate assembly 80a may be applied to connect various parts. For example, the main body 10 of the refrigerator 1 may include the plate assembly 80a. For example, the door 30 of the refrigerator 1 may include the plate assembly 80a. In addition, as described above, the plate assembly 80a may be applied to a variety of household appliances other than the refrigerator 1.

The first ridge 121a of the first coupling protrusion 121 may be configured to be locked with the locking portion 222. The first coupling protrusion 121 may be restricted from moving in the first direction A and / or the second direction B while being locked with the locking portion 222.

[0187] The second coupling protrusion 122 may be inserted into the opening 221 and coupled to the locking portion 222. The second coupling protrusion 122 may be inserted into the opening 221 and locked with the locking portion 222. The second ridge 122a of the second coupling protrusion 122 may be configured to be locked with the locking portion 222. The second coupling protrusion 122 may be restricted from moving in the first direction A and / or the second direction B while being locked with the locking portion 222.

[0188] Generally, for example, a screw fastening method may be used for assembly between parts. In this case, a separate device (e.g., a screwdriver, etc.) may be required for screw fastening, and the working time may be relatively long. When the screw is over-tightened, the exterior of the part may be squeezed. For example, when the thickness of the intermediate member is thick, the exterior of the part may be damaged during screw fastening.

[0189] As another example, a hooking method may be used to assemble parts. In this case, when assembling one hook, another hook that has been assembled may be disassembled. That is, it may cause the inconvenience of having to reassemble the hook. In addition, when the hook is over-tightened, the exterior of the parts may be squeezed. For example, when the thickness of the intermediate member is thick, the exterior of the parts may be damaged during the hooking assembly process.

[0190] According to the present disclosure, the first plate 100 and the second plate 200 can be easily connected to each other. The first connection part 120 and the second connection part 220 can be connected to each other without a separate fastening member (e.g., a screw, a screwdriver, etc.). The first connection part 120 and the second connection part 220 can be configured to achieve a one-touch connection. For example, an operator can assemble the first connection part 120 and the second connection part 220 by pushing one of the connection parts in the first connection part 120 and the second connection part 220 using a finger or an assembly jig. In addition, in a state where the first connection part 120 and the second connection part 220 are locked together, the connection of the first connection part 120 with the second connection part can be firmly maintained without a predetermined force being applied to the first connection part 120 and the second connection part 220. As described above, the connection of the first plate 100 and the second plate 200 can be promoted, and the working time can be shortened. As a result, the assemblability and productivity of the plate assembly 80a can be improved.

[0191] In addition, the first plate 100 may be exposed to the outside of the household appliance, and the second plate 200 may be covered by the first plate 100 without being exposed to the outside. Since the second plate 200 includes the slit 230, the rigidity of the second plate 200 may be weaker than that of the first plate 100. For example, in a state where the first plate 100 and the second plate 200 are coupled to each other, stress may be concentrated on the end of the slit 230 and / or a portion of the coupling body 223. For example, stress may be concentrated on the end of the second slit forming part 230b, the end of the third slit forming part 230c, and the second part 2232 of the coupling body 223. That is, stress will not be concentrated on the first plate 100. Therefore, when the first coupling part 120 and the second coupling part 220 are coupled to each other, only the second plate 200 having relatively weak rigidity may be deformed. As a result, the external appearance of the first plate 100 exposed to the outside of the household appliance may not be squeezed. The aesthetics of the plate assembly 80a will not be deteriorated.

[0192] The support member 300 may be arranged to be in surface contact with at least one of the first plate 100 or the second plate 200. When the first coupling portion 120 and the second coupling portion 220 are coupled to each other, the first plate 100 and the support member 300 may be in close contact with each other. When the first coupling portion 120 and the second coupling portion 220 are coupled to each other, the second plate 200 and the support member 300 may be in close contact with each other. For example, even when the thickness of the support member 300 is small, the second coupling portion 220 may be coupled to the first coupling portion 120 when deformed. Therefore, the air tightness of the plate assembly 80a may be improved. For example, when the plate assembly 80a is applied to the cold air duct 80, the cold air flowing inside the cold air duct 80 will not flow to the outside, or the humid air will not flow into the cold air duct 80.

[0193] Fig.10 is a cross-sectional view illustrating a state in which a first plate and a second plate of a plate assembly according to an embodiment are coupled. Fig.11 It is shown in Fig.10 0 is a cross-sectional view of a state in which a first plate and a second plate of a plate assembly shown in FIG. 1 are being detached from each other. Fig.12 It is shown in Fig.11 0 is a cross-sectional view of a state in which the first plate and the second plate of the plate assembly shown in 0 are detached from each other.

[0194] refer to Figures 10 to 12 An example of a process of disassembling the panel assembly 80a is described.

[0195] refer to Fig.10 , in a state where the first coupling portion 120 and the second coupling portion 220 are coupled to each other, at least a portion of the first coupling portion 120 may be configured so that at least a portion of the first coupling portion 120 can be accessed or approached through the opening 221 of the second coupling portion 220. For example, the tool T1 may be inserted into the groove 127 of the first coupling protrusion 121 through the opening 221. For example, the tool T1 may be inserted into the groove 128 of the second coupling protrusion 122 through the opening 221. For example, the tool T1 may have a substantially pliers shape. For example, the tool T1 may be a long nose pliers. Moreover, although not shown in the drawings, the operator may insert a finger, instead of the tool T1, into at least one of the grooves 127 or 128.

[0196] refer to Fig.11, in a state where the first plate 100 and the second plate 200 are coupled to each other, the first coupling protrusion 121 and the second coupling protrusion 122 may be pushed to be brought together. The first coupling protrusion 121 and the second coupling protrusion 122 may be configured to be brought together by a tool T1, a worker's finger, etc. When the first coupling protrusion 121 and the second coupling protrusion 122 are brought together, the bridge 123 may be elastically deformed. The first bridge portion 125 and the second bridge portion 126 may be brought together. Therefore, the coupling between the first coupling portion 120 and the second coupling portion 220 may be released. The first coupling portion 120 and the second coupling portion 220 may be separated from each other. The locking of the first coupling portion 120 and the second coupling portion 220 may be released. The coupling between the first coupling protrusion 121 and the locking portion 222 may be released. The coupling between the second coupling protrusion 122 and the locking portion 222 may be released.

[0197] refer to Fig.12 , when the coupling between the first coupling portion 120 and the second coupling portion 220 is released, the first plate 100 and the second plate 200 may be disassembled from each other. When the locking of the first coupling portion 120 and the second coupling portion 220 is released, the second plate 200 may be configured to move away from the first plate 100 by a repulsive force. In a state where the first plate 100 and the second plate 200 are coupled to each other, the slit 230 may cause a force to act on the second plate 200 in a direction to separate from the first plate 100. For example, as an external force pushes on the first coupling portion 120 and the first coupling portion 120 is disengaged from the second coupling portion 220, the second coupling portion 220 may be biased in a direction away from the first plate 100 by the slit 230. Therefore, when the first coupling portion 120 and the second coupling portion 220 are separated from each other, the slit 230 may be configured to allow the second plate 200 to rebound against the first plate 100 or to bounce away from the first plate 100. For example, in a state where the first plate 100 and the second plate 200 are coupled to each other, when the first coupling portion 120 is deformed along the third direction C, the second portion ( Figure 7 2232) in the first direction A may be configured to rebound in the first direction A. As a result, the detachment of the first coupling portion 120 from the second coupling portion 220 may be facilitated. The first coupling portion 120 and the second coupling portion 220 may be configured to achieve one-touch detachment.

[0198] Fig.13 is a cross-sectional view illustrating a state in which a first plate and a second plate of a plate assembly according to an embodiment are coupled. Fig.14 It is shown in Fig.13 0 is a cross-sectional view of a state in which a first plate and a second plate of a plate assembly shown in FIG. 1 are being detached from each other. Fig.15 It is shown in Fig.140 is a cross-sectional view of a state in which the first plate and the second plate of the plate assembly shown in 0 are detached from each other.

[0199] refer to Figures 13 to 15 An example of a process of disassembling the panel assembly 80a is described.

[0200] refer to Fig.13 , in a state where the first coupling portion 120 and the second coupling portion 220 are coupled to each other, at least a portion of the first coupling portion 120 may be configured so that at least a portion of the first coupling portion 120 can be accessed or approached through the opening 221 of the second coupling portion 220. For example, the tool T2 may be inserted into the recessed portion 124 of the bridge 123 through the opening 221. For example, the tool T2 may have a shape extending in substantially one direction. For example, the tool T2 may be a slotted screwdriver. In addition, although not shown in the drawings, the operator may insert a finger, instead of the tool T2, into the recessed portion 124 of the bridge 123.

[0201] refer to Fig.14 , the bridge 123 may be pushed in a state where the first plate 100 and the second plate 200 are coupled to each other. In a state where the first plate 100 and the second plate 200 are coupled to each other, the recessed portion 124 of the bridge 123 may be pushed in the second direction B. As the recessed portion 124 of the bridge 123 is pushed in the second direction B, the first coupling protrusion 121 and the second coupling protrusion 122 may be brought together. As the recessed portion 124 of the bridge 123 is pushed in the second direction B, the first coupling protrusion 121 and the second coupling protrusion 122 may be arranged to be brought together. The first coupling protrusion 121 and the second coupling protrusion 122 may be elastically deformed. Therefore, the coupling between the first coupling portion 120 and the second coupling portion 220 may be released. The first coupling portion 120 and the second coupling portion 220 may be separated from each other. The locking of the first coupling portion 120 and the second coupling portion 220 may be released. The coupling between the first coupling protrusion 121 and the locking portion 222 may be released. The coupling between the second coupling protrusion 122 and the locking portion 222 may be released.

[0202] refer to Fig.15, when the connection between the first coupling portion 120 and the second coupling portion 220 is released, the first plate 100 and the second plate 200 may be detached from each other. When the locking of the first coupling portion 120 and the second coupling portion 220 is released, the second plate 200 may be configured to move away from the first plate 100 by a repulsive force. In a state where the first plate 100 and the second plate 200 are coupled to each other, the slit 230 may cause a force to act on the second plate 200 in a direction to separate from the first plate 100. Therefore, in response to the first coupling portion 120 and the second coupling portion 220 being separated from each other, the slit 230 may be configured to allow the second plate 200 to rebound against the first plate 100. For example, in a state where the first plate 100 and the second plate 200 are coupled to each other, when the first coupling portion 120 is deformed in the second direction B, the second portion ( Figure 7 2232) in the first direction A may be configured to rebound in the first direction A. As a result, the detachment of the first coupling portion 120 from the second coupling portion 220 may be facilitated. The first coupling portion 120 and the second coupling portion 220 may be configured to achieve one-touch detachment.

[0203] Fig.16 is an enlarged view illustrating a portion of an example of a plate assembly according to one embodiment. Fig.17 is Fig.16 A cross-sectional view of the plate assembly shown in FIG. Fig.18 It is shown in Fig.17 0 is a cross-sectional view of a state in which a first plate and a second plate of a plate assembly shown in FIG. 1 are being detached from each other.

[0204] refer to Figures 16 to 18 An example describing the process of disassembling a board assembly. Figures 16 to 18 The shape of the slits in the plate assembly shown in Figures 5 to 15 The shape of the slits in the plate assembly shown in FIG. Other configurations can be compared with reference Figures 5 to 15 The construction of the plate assembly described in Figures 16 to 18 When the plate assembly is shown in FIG. 1 , the same reference numerals are given as with reference Figures 5 to 15 The configuration of the plate assembly 80a described above is the same configuration, and a detailed description thereof may be omitted.

[0205] refer to Fig.16 The slit 230 may include a first slit portion 231a and a second slit portion 231b spaced apart from the first slit portion 231a. For example, in a state where the first plate 100 and the second plate 200 are coupled to each other, the first coupling portion 120 may be disposed between the first slit portion 231a and the second slit portion 231b.

[0206] For example, the first slit portion 231a and the second slit portion 231b may be disposed symmetrically with respect to the second line L2. The second line L2 may pass through the center of the opening 221 while extending along a fourth direction D intersecting the third direction C. For example, the fourth direction D may be perpendicular to the third direction C. For example, the first slit portion 231a and the second slit portion 231b may be disposed in pairs.

[0207] For example, the slit 230 may include a fourth slit forming portion 230d that is spaced apart from the opening 221 and extends along the fourth direction D. For example, the fourth slit forming portion 230d may be spaced apart from the opening 221 by a predetermined distance along the third direction C. For example, the fourth slit forming portion 230d may extend linearly along the fourth direction D. For example, the fourth slit forming portion 230d may have a linear shape.

[0208] For example, the slit 230 may include a fifth slit forming portion 230e extending from one side of the fourth slit forming portion 230d toward the opening 221 along the third direction C. For example, the fifth slit forming portion 230e may extend linearly along the third direction C. For example, the fifth slit forming portion 230e may have a linear shape.

[0209] For example, the slit 230 may include a sixth slit forming portion 230f extending from the other side of the fourth slit forming portion 230d toward the opening 221 along the third direction C. For example, the sixth slit forming portion 230f may extend linearly along the third direction C. For example, the sixth slit forming portion 230f may have a linear shape.

[0210] For example, each of the first slit portion 231 a and the second slit portion 231 b may include a fourth slit forming portion 230 d , a fifth slit forming portion 230 e , and a sixth slit forming portion 230 f .

[0211] The second plate 200 may include a wing portion 240. The slit 230 of the second plate 200 may form the wing portion 240. The slit 230 of the second plate 200 may be configured to define the wing portion 240. For example, the wing portion 240 may be a portion surrounded by the slit 230 and the coupling body 223. For example, the wing portion 240 may be configured to be elastically deformable.

[0212] For example, the second plate 200 may include a first wing portion 241 formed by the first slit portion 231a. For example, the first wing portion 241 may be formed by the fourth slit forming portion 230d, the fifth slit forming portion 230e, and the sixth slit forming portion 230f of the first slit portion 231a. The first wing portion 241 may have a cantilever shape.

[0213] For example, the second plate 200 may include a second wing portion 242 formed by the second slit portion 231b. For example, the second wing portion 242 may be formed by the fourth slit forming portion 230d, the fifth slit forming portion 230e, and the sixth slit forming portion 230f of the second slit portion 231b. The second wing portion 242 may have a cantilever shape.

[0214] For example, the first wing portion 241 and the second wing portion 242 may be disposed to be symmetrical with respect to the second line L2.

[0215] refer to Fig.17 , the first coupling portion 120 and the second coupling portion 220 may be coupled to each other. The first coupling portion 120 may be inserted into the support hole 320 and coupled to the second coupling portion 220. The first coupling portion 120 may be locked with the second coupling portion 220. The first coupling protrusion 121 may be inserted into the opening 221 and locked with the locking portion 222. The second coupling protrusion 122 may be inserted into the opening 221 and locked with the locking portion 222. In a state where the first coupling portion 120 and the second coupling portion 220 are locked with each other, the first plate 100 and the second plate 200 may be prevented from being disassembled.

[0216] refer to Fig.18 , when the locking of the first coupling portion 120 and the second coupling portion 220 is released, the first plate 100 and the second plate 200 may be detached from each other. When the locking of the first coupling portion 120 and the second coupling portion 220 is released, the second plate 200 may be configured to move away from the first plate 100 by a repulsive force. For example, when the first coupling protrusion 121 and the second coupling protrusion 122 are brought close together, the locking of the first coupling portion 120 and the second coupling portion 220 may be released.

[0217] In a state where the first plate 100 and the second plate 200 are coupled to each other, the slit 230 may cause a force to act on the second plate 200 in a direction of separation from the first plate 100. Therefore, when the locking of the first coupling portion 120 and the second coupling portion 220 is released, the first plate 100 and the second plate 200 may be easily separated. As a result, the disassembly of the first coupling portion 120 and the second coupling portion 220 may be facilitated. The first coupling portion 120 and the second coupling portion 220 may be configured to achieve one-touch disassembly.

[0218] For example, when the locking of the first coupling portion 120 and the second coupling portion 220 is released, the wing portion 240 formed by the slit 230 can allow the second plate 200 to rebound from the first plate 100. When the locking of the first coupling portion 120 and the second coupling portion 220 is released, the wing portion 240 can be configured to generate a repulsive force. For example, the wing portion 240 can be used as a cantilever. For example, when the locking of the first coupling portion 120 and the second coupling portion 220 is released, the free end of the wing portion 240 can move downward within a predetermined range.

[0219] At the same time, Figures 16 to 18 In FIG. 1 , the first coupling portion 120 of the first plate 100 is illustrated as not including the bridge 123, but is not limited thereto.

Since this has been described above, a detailed description thereof will be omitted.

Since the cap 400 is provided to cover the opening 221, humid air may be prevented from being introduced into the opening 221.

[0222] For example, the cap 400 may include a cap protrusion 410. When the cap 400 is mounted on the opening 221, the cap protrusion 410 may be configured to be locked with the second plate 200. Although not shown in the drawings, the second plate 200 may include a groove corresponding to the cap protrusion 410.

The same reference numerals are given to Figures 5 to 15 The configuration of the board assembly described is the same configuration, and a detailed description thereof may be omitted.
