Definitions

  • the present disclosure relates to an assembly set comprising a drip tray and a fan assembly, it further refers to refrigerator having a compact machine compartment.
  • a machine compartment may be provided in a rear lower portion of a refrigerator.
  • the machine compartment may accommodate a compressor and a condenser that generate heat in a refrigerating cycle of the refrigerator.
  • a drip tray configured to receive defrosted water as generated in an evaporator used to cool a cabinet of the refrigerator may be provided in the machine compartment.
  • the defrosted water stored in the drip tray may be evaporated by the heat released from the compressor and condenser of the machine compartment.
  • the drip tray may have a flat and wide shape to widen a surface area in contact with the atmosphere.
  • the machine compartment may include a fan which generates an air flow through the compressor and the condenser. The air flow may be used to evaporate the water contained in the drip tray.
  • a drip tray 8 may have a form of a tray having a rectangular broad bottom member 87 and an outer wall 85 having a small vertical dimension and extending upwardly from an edge of the bottom member. The defrosted water may be received in a space defined by the bottom member and the outer wall.
  • defrosted water W may be stored in the drip tray 8.
  • a fan assembly 9 may be provided above the bottom member 87 of the drip tray 8.
  • the fan assembly 9 may be placed on a fan assembly support 89 provided inside the drip tray 8 and may be fixed to the fan assembly support 89 by a fastener such as a screw b. Further, a lower end of the fan assembly 9 may be interposed between two outer walls 85 of the tray drip 8.
  • a height h of the machine compartment housing the drip tray 8 and the fan assembly 9 may be determined by a distance between a bottom boundary 13 extending horizontally from the bottom member 87 of the tray drip 8 and a top boundary 14 extending horizontally from a top of the fan assembly 9. That is, the height h of the machine compartment according to FIGs. 1 and 2 may be equal to a sum of a height of the fan assembly support 89 and a height of the fan assembly 9.
  • a depth d of the machine compartment according to FIGs. 1 and 2 may be determined by a distance between the two parallel and spaced outer walls 85 of the drip tray 8 defining a space receiving the lower end of the fan assembly 9. According to the combined structure of the drip tray 8 and the fan assembly 9 in FIGs. 1 and 2 , reducing the height h and depth d of the machine compartment should result from the reduction of the size of the fan assembly 9. However, when the size of the fan assembly 9 is reduced, there may be a problem that a fan flow rate is reduced correspondingly.
  • the object is therefore to provide a drip tray for a refrigerator allowing the fan assembly to be assembled into a machine compartment or installation space of the refrigerator to have a reduced installation height and more efficient space utilization of the machine compartment or installation space to further increase the storing space of the refrigerator without increasing outside dimensions. Furthermore, the efficiency of the fan with respect to the amount of water stored in the drip tray should be increased.
  • Another object is to provide a drip tray and fan assembly which may be easily placed inside a compact machine compartment.
  • An embodiment of a drip tray provided in a machine compartment may include, as shown in FIG. 3 , a bottom member or panel 77 formed of a plate having a substantially rectangular shape, and an outer or first wall 75 that extends upward from an edge of the bottom panel 77.
  • the bottom panel 77 may be made of metal or plastic.
  • the bottom panel 77 may have a rectangular shape including short sides and long sides. Along a predetermined length at the long side edge of the bottom panel 77, an opening 78 at which the outer wall is not formed may be defined. That is, the outer wall may extend upward from the edge of the bottom panel 77 along a periphery of the bottom panel 77 except for the opening 78 region.
  • the drip tray 7 may include an inner or second wall 76 that extends from both ends of the opening 78 of the bottom panel 77.
  • the inner wall 76 may extend in a perpendicular manner to the long side of the bottom panel 77 and may extend along the bottom panel 77. That is, the inner wall 76 may extend inward from the long side of the bottom panel 77.
  • the direction in which the inner wall 76 extends inward from the long side of the bottom panel 77 may be parallel to the extending direction of the short side of the bottom panel 77.
  • the inner wall 76 may extend upward from the bottom panel 77.
  • the inner wall 76 may be connected to the outer wall 75 at the opening 78.
  • the inner wall 76 may have a " ⁇ " shape (U-shape). That is, an opposite portion to the opening 78 may be closed.
  • the inner wall 76 may include a first inner wall and a second inner wall, and both may extend in a direction parallel to the short side of the bottom panel 77, and a third inner wall that connects distal ends of the first and second inner walls to each other. That is, the proximal ends of the first inner wall and the second inner wall may be connected to the outer wall 75 of the bottom panel 77, while the distal ends of the first inner wall and the second inner wall may be interconnected via the third inner wall.
  • the first inner wall and the second inner wall may extend parallel to each other and may be parallel to the short side of the bottom panel 77.
  • the third inner wall may be shorter than each of the first and second inner walls.
  • the third inner wall may be parallel to the long side of the bottom panel 77.

That is, the outer wall 75 may define all the edges of the bottom panel 77 except for the opening 78.
  • the inner wall 76 may be connected to the outer wall 75 and may extend inward from an edge of the bottom panel 77. Accordingly, the outer wall 75 and the inner wall 76 of the drip tray 7 may form a closed loop.
  • a space defined by the bottom panel 77 and the closed loop formed by the outer wall 75 and the inner wall 76 may define a defrosted water storage space (or water storage space) 71.
  • the water storage space 71 for defrosted water may be divided into two spaces. The two spaces are divided by the inner wall 76, in particular by the inner wall 76 protruding from the edge of the bottom panel 77 to the inside of the area of the bottom panel 77.
  • a first storage space 711 may be defined to one side of the inner wall 76 along the longitudinal direction of the long side of the bottom panel 77, while a second storage space 712 may be defined to the other side of the inner wall 76 along the longitudinal direction of the long side of the bottom panel 77.

  • a space excluding the defrosted water storage space 71 defined by the first storage space 711, the second storage space 712, and the communication space 713 may define a fan assembly accommodation space (or fan assembly mounting space) 73 into which the defrosted water w does not invade.

  • the fan assembly accommodation space 73 may not accommodate defrosted water therein. Thus, in the location of the fan assembly accommodation space 73, a portion or all of the bottom panel 77 may be removed. When a portion or all of the bottom panel 77 is removed in this manner, the water w may drain immediately therefrom even when the defrosted water w penetrates into the fan assembly accommodation space 73. This may reduce a risk that water will penetrate into the motor 42 of the fan assembly 3, which will be described later, provided in the fan assembly accommodation space 73.
  • the fan assembly accommodation space 73 may have one short side that defines the opening 78.
  • the water drain may be realized. Therefore, for drainage, the portion or all of the bottom panel 77 may not be removed intentionally.
