Definitions

  • the present invention relates to a household appliance, and more particularly to an adjustment mechanism and a household appliance having the same.
  • a household appliance conventionally has a drawer-type door.
  • a drawer-type door is supported on a cabinet through a support structure to close or open a storage compartment.
  • Storage boxes for placing food, fruits and vegetables are installed on the drawer-type door.
  • a gasket having magnetic attraction to the cabinet of the refrigerator is disposed along the edge of the rear side of the drawer-type door, so that when the drawer-type door is closed, the gasket closely contacts the front side of the main body of the refrigerator.
  • An error may inevitably occur during the installation of the drawer-type door to the cabinet. For example, a deviation may be caused in a vertical direction of the drawer-type door relative to the original design.
  • the loaded storage box may also cause the door body to displace downward.
  • the position displacement of the drawer-type door relative to the cabinet may even cause a serious consequence that gaps appear between the gasket and the main body of the refrigerator and lead to cold air leakage.
  • an inappropriate positional relationship between the door and the cabinet may also affect the appearance of the refrigerator.
  • An objective of the present invention is to provide an adjustment mechanism which has a simple structure and a low cost and is easy to operate.
  • Another objective of the present invention is to provide a household appliance having the adjustment mechanism.
  • the present invention provides an adjustment mechanism, for adjusting a positional relationship between a first member and a second member in an adjustment direction.
  • the adjustment mechanism includes: at least one adjustment hole and at least two spaced apart fixation holes, disposed on one of the first member and the second member; at least three mating holes, disposed on the other of the first member and the second member, the at least three mating holes including at least one first mating hole for mating with the at least one adjustment hole respectively and second mating holes for mating with the at least two fixation holes respectively, and when a center of any one fixation hole coincides with a center of the corresponding second mating hole, a center of the remaining fixation hole being spaced from a center of the corresponding second mating hole in the adjustment direction; and at least two connection members, one connection member passing through the fixation holes and the second mating holes with coincident centers, and the other connection member passing through the adjustment hole and the first mating hole, so as to fix the first member and the second member.
  • the adjustment mechanism of such a simple structure can be used to conveniently adjust a positional relationship between two members.
  • the holes for fixing the first member and the second member form an adjustment structure, so that no additional part is required, and the cost is reduced.
  • the centers of the at least two fixation holes are arranged in a line in the adjustment direction, which is convenient for punching and assembly.
  • the centers of the at least one adjustment hole and the at least two fixation holes are arranged in a line in the adjustment direction.
  • the centers of the at least two fixation holes have a distance therebetween in a direction perpendicular to the adjustment direction, that is, the centers of the at least two fixation holes may not be arranged in a line in the adjustment direction, and can be disposed at any positions as long as it is ensured that the fixation holes correspond to the corresponding mating holes, which is convenient for actual connections.
  • the adjustment mechanism includes at least two adjustment holes, the at least two fixation holes being located between the two adjustment holes, so that the connection is more secured and the operation is more convenient.
  • the adjustment hole is a slot hole, and the relative positions of a fixed member and the door are changed by adjusting the position of a screw in the slot hole.
  • An error of the door in a vertical direction can be adjusted by using the slot hole in a certain range instead of with a set value, because an exact value of the displacement error of the door in the vertical direction is unpredictable, but the error range is predictable, so that the slot hole can be used to eliminate the error according to the actual condition.
  • connection members are screws and connect the first member and the second member by threaded connection, which is simple, convenient, and quite reliable.
  • one of the at least two fixation holes is a reference fixation hole, and when a center of the reference fixation hole coincides with a center of the corresponding second mating hole, a center of the at least one adjustment hole exactly coincides with a center of the corresponding first mating hole.
  • the adjustment mechanism includes at least three pairs of paired fixation holes and second mating holes.
  • the center of the reference fixation hole coincides with the center of the corresponding second mating hole, the remaining fixation holes are equally spaced from the pairing second mating holes in the adjustment direction.
  • the adjustment mechanism includes at least three pairs of paired fixation holes and second mating holes.
  • the fixation holes include a reference fixation hole, and when a center of the reference fixation hole coincides with a center of the pairing second mating hole, the remaining fixation holes are equally spaced from the pairing second mating holes in the adjustment direction.
