Definitions

  • the present invention relates to refrigeration field and, in particular, to a barrier structure and a refrigeration appliance equipped with the barrier structure.
  • a traditional cabinet comprises an outer shell and an inner shell disposed by a distance from the outer shell.
  • a foaming process should be performed between the outer shell and the inner shell to inject a foam material into the gap between them for forming a thermal insulating layer, so as to block or reduce heat exchange between the inside and outside of the refrigerator.
  • the refrigerator is provided with many structural members.
  • Chinese patent No. CN1119604C discloses a barrier structure for refrigerator, the barrier structure of the refrigerator being arranged inside the cabinet of the refrigerator to divide a freezing compartment and a refrigerating compartment therein.
  • the barrier structural member comprises a seat body and a barrier plate mounted to the seat body.
  • the seat body is mounted to a lower front portion of the cabinet of the refrigerator (i.e. an adjoining portion between the front portion and the bottom portion of the cabinet of the refrigerator).
  • the seat body has a generally prism shape, having a length corresponding to the width of the cabinet of the refrigerator.
  • the barrier plate has a flat shape and comprises several mounting holes in its opposite short sides and a flange on a long side of it.
  • the flange of the barrier plate is attached to the seat body, to align the mounting holes of the barrier plate with corresponding mounting holes formed in the seat body. Then, the barrier plate is assembled to the seat body by using fasteners such as screws, bolts, rivets or the like.
  • the mounting holes of the barrier plate are arranged at opposite sides of the barrier plate and are separated from each other by a relatively long distance, and the assembling of the barrier plate to the seat body is achieved only by fastening and locking effects of fasteners such as screws, bolts, rivets or the like.
  • fasteners such as screws, bolts, rivets or the like.
  • the barrier plate is liable to bulge out under the pressure imparted by foam material.
  • the barrier plate becomes uneven, which will affect the structural strength and the appearance of the barrier plate.
  • the mounting holes of the barrier plate are not exactly aligned with the mounting holes of the seat body due to manufacturing techniques, so that there are misalignments between them. This is undesirable for fastening the screws, bolts, rivets or the like.
  • An object of the present invention is to provide a barrier structure and a refrigeration appliance equipped with the barrier structure to eliminate the disadvantages of the prior art, such as low structural strength of the barrier structure and low positioning accuracy in assembling.
  • the present invention provides a barrier structure for a refrigeration appliance which comprises: a seat adapted to be mounted to the bottom of a cabinet of the refrigeration appliance, the seat having a bottom surface and a mounting surface adjoining the bottom surface, with an edge portion of the bottom surface which adjoining the mounting surface being provided with at least one first retention portion; and a barrier plate member having a barrier plate body adapted to be fitted to the mounting surface and a side flap connected to the barrier plate body, the side flap being provided with a second retention portion for engaging with the first retention portion on the bottom surface of the seat.
  • the first retention portion is provided in the middle area of the edge portion of the bottom surface which adjoining the mounting surface, and the second retention portion is provided in the middle area of the side flap of the barrier plate member.
  • the first retention portion is a boss
  • the second retention portion is a catch hole which is inserted into by the boss.
  • the catch hole has a crescent shape which is narrowed from its middle section towards its opposite lateral sides, and the height of the boss corresponds to the height of the middle section of the catch hole.
  • a first mounting portion is provided on each of opposite sides of the barrier plate body in its lengthwise direction
  • a second mounting portion is provided on each of opposite sides of the mounting surface of the seat in its lengthwise direction, corresponding to the first mounting portion of the barrier plate body.
  • the first mounting portion is a through hole which has an aperture dimension in the lengthwise direction of the barrier plate body larger than the aperture dimension of the through hole in the widthwise direction of the barrier plate body, and the second mounting portion is a mounting hole.
  • the through hole is an oblong hole, an oval hole or a rectangular hole.
  • the barrier plate member further comprises two lateral flaps extending in the lengthwise direction of the barrier plate body, with each lateral flap being provided with a third mounting portion, and the opposite sides of the seat are provided with fourth mounting portions corresponding to the third mounting portions of the barrier plate body respectively.
  • the third mounting portion is a through hole
  • the fourth mounting portion is a mounting hole
  • the present invention also provides a refrigeration appliance quipped with a barrier structure as described above.
  • the inventor of the present invention inventively discovered that, in the barrier structure of the prior art, the barrier plate is mounted to seat body by means of the mounting holes formed on opposite short sides of the barrier plate. Since the barrier plate is relatively long, and thus the distance between the mounting holes is too large, the barrier plate (especially the middle area of it) lacks effective protective retention or fixation in the foaming process. As a result, the barrier plate is liable to bulge or warp in the foaming process under pressure force imparted by foam material. Thus, the barrier plate becomes uneven, which affects the joining between the barrier plate and the seat body as well as the whole structural strength of the barrier structure.
  • the present invention provides a barrier structure and a refrigeration appliance equipped with the barrier structure.
  • the barrier structure comprises: a seat adapted to be mounted to the bottom of a cabinet of the refrigeration appliance, the seat having a bottom surface and a mounting surface adjoining the bottom surface, with an edge portion of the bottom surface which adjoining the mounting surface being provided with at least one first retention portion; and a barrier plate member having a barrier plate body adapted to be fitted to the mounting surface and a side flap connected to the barrier plate body, the side flap being provided with a second retention portion for engaging with the first retention portion on the bottom surface of the seat.
  • the claimed barrier structure and refrigeration appliance equipped with the barrier structure has advantages, such as having high structural strength.
