  • Patent number: 10724784
    Abstract: A household appliance has a case body and a door that is pivotable about a rotation axis relative to the case body. The door includes a doorframe and a front door panel connected to a front side of the doorframe. The front door panel includes a protruding portion that extends out of the doorframe along a length or width direction of the door, and the door further includes a cover member disposed behind the protruding portion. The structure of the door is thus more diversified, to ensure a function of the door, and at the same time, meet an appearance requirement of industrial design.

  • Patent number: 10465969
    Abstract: A refrigerator includes a case body; a first door, pivotally connected to the case body by using a first hinge; and a second door, pivotally connected to the first door by using a second hinge. The top of the first door is provided with a first installation portion adapted to install the first hinge and a second installation portion adapted to install the second hinge. The second installation portion includes a groove recessed downwards from the first installation portion. The solution of the present invention can reserve more space for movement of a door body along a height direction, thereby avoiding interference between the first hinge and the second hinge.

  • Patent number: 10274248
    Abstract: A refrigeration appliance includes a case body and a door connected to the case body. The door includes a doorframe, a container connected to the back of the doorframe, and a foamed heat insulation material located between the doorframe and the container. The door has a through hole that extends in a front-to-rear direction. The doorframe has a first wall facing the through hole. The container has a second wall facing the through hole. The first wall and the second wall are superposed and clamped to form an inner wall of the through hole. This solution can avoid displacement between the doorframe and the container, thereby avoiding foam leakage.
