A vacuum adiabatic body includes a heat exchange pipeline and a sealing plug. The heat exchange pipeline includes at least two pipelines which pass through a first plate and a second plate to allow a refrigerant to move between inner and outer spaces. The sealing plug allows the heat exchange pipeline to pass through a first point of the first plate and a second point of the second plate without contacting a third space.

A water storage box and a refrigerator; the water storage box includes a box body and a front panel provided on a front end surface of the box body, and further includes: a locking structure including a locking part and a fitting part, one of the locking part and the fitting part being provided on a rear surface of the front panel, the other of the locking part and the fitting part being provided on the front end surface, and the locking structure being provided near a first side of the front end surface; at least one overturning structure provided between the rear surface and the front end surface, the at least one overturning structure being provided close to a second side of the front end surface, and the first side being opposite to the second side.

A refrigerator includes a cabinet, a first inner case that defines a freezing compartment, a second inner case that defines a refrigerating compartment, a thermal siphon unit that is configured to carry a working fluid for heat transfer and that has a closed loop shape that includes a first part arranged at an outer side of the first inner case and a second part arranged at an outer side of the second inner case, and a cool air storage unit arranged in a space partitioned in the first inner case. The cool air storage unit is configured to accommodate cool air of the freezing compartment and transfer the cool air to the first part of the thermal siphon unit arranged outside of the first inner case.

A refrigerator includes a cabinet, a mounting bracket disposed at a top surface of the cabinet, a door configured to rotate relative to the cabinet, a hinge cover that is disposed at the top surface of the cabinet and covers the mounting bracket, a hinge including a door bracket disposed at the door, a hinge bracket disposed at the mounting bracket, and a plurality of links that connect the door bracket to the hinge bracket, a guide device having a first side disposed at the door and a second side that passes through a cover opening at a front surface of the hinge cover and is disposed inside the hinge cover, and an electric wire or a water pipe disposed along an inside of the guide device.

A domestic refrigerator (1) comprises a thermally insulated housing (2), a cold storage compartment (5) and a fresh food compartment (4) contained within the housing (2) and located on top of each other, a refrigerant circuit which comprises an evaporator (29) configured to directly cool the cold storage compartment (5), a first door leaf (18) for closing and opening the fresh food compartment (4), a second door leaf (19) for closing and opening the cold storage compartment (5), a divisional wall (17, 42) separating the cold storage compartment (5) from the fresh food compartment (5), and a air channel system (31, 32) which is configured to allow an air exchange between the cold storage compartment (5) and the fresh food compartment (4).

A seal includes a buckling portion. The buckling portion is composed of two H-shaped members that are flexibly connected. The two H-shaped members are buckled with each other to form a mounted state. The H-shaped member has a first arm and a second arm which are parallel to each other, and a connecting portion which connects the first arm and the second arm. The connecting portion has an arcuate surface. The arcuate surfaces of the two H-shaped members cooperatively define a hollow cavity when the two H-shaped members are in the mounted state. A vacuum assembly and a refrigerator are disclosed to respectively have the seal.

A rear plate of a refrigerator includes a base section formed at the outside of the rear plate while being flat, and a formed section formed to protrude from the base section toward the inner case through a foaming process. Outer equipment is installed at the formed section, to be disposed more inside than the base section and, as such, it is possible to protect the outer equipment from external impact. In addition, it is possible to achieve an improvement in rear appearance design of the refrigerator and an enhancement in space utility of the refrigerator.

A refrigerator having an improved structure configured to increase the energy efficiency includes a main body provided with an inner case and an outer case, a storage compartment formed inside of the inner case, an insulation material provided between the inner case and the outer case to insulate the storage compartment and a flange having the anisotropy having different heat resistance distribution to insulate the storage compartment, together with the insulation material.

A refrigerator includes a refrigerator main body configured to define an outer shell of the refrigerator and a door configured to open and close an internal space of the refrigerator main body. The refrigerator further includes an ice-making unit provided in the door and a cold air generation unit configured to circulate a refrigerant so that a cold air is supplied to the internal space. The refrigerator further includes an ice-making pipe installed within the ice-making unit so that the ice-making unit makes heat exchange with the refrigerant, a refrigerant pipe installed in the refrigerator main body so as to receive the refrigerant from the cold air generation unit, and a soft pipe disposed around a folding portion of the refrigerator main body and the door and configured to interconnect the ice-making pipe and the refrigerant pipe in a stretchable manner.

An ice-maker in a refrigerator is capable of producing ice pieces through directly cooling by a refrigerant circulating in a cold air generation system. An ice-making pipe is installed within the ice-making unit and has the refrigerant flowing therein. A refrigerant pipe is installed in the refrigerator main body for receiving the refrigerant from the cold air generation system. A flexible pipe is disposed around hinged end portions (e.g., corners) of the refrigerator main body and the door and configured to interconnect the ice-making pipe and the refrigerant pipe in an extendable manner. A control valve can cut off a flow of the refrigerant flowing between the ice-making pipe and the refrigerant pipe, for example when the door is to be removed for repair or replacement.
