The present invention provides a refrigerator, a duct assembly and a duct fixture. The duct fixture includes a fixing seat having a through hole, a fixing disk, a limiting block disposed on a side of the fixing disk adjacent to a target mounting surface, and a positioning protrusion disposed on the fixing disk, an outer shape of the limiting block matches a mounting hole on the target mounting surface, a limiting groove for receiving the target mounting surface is formed between the limiting block and the fixing disk, and the positioning protrusion is disposed angularly with the limiting block around the central axis of the through hole. When the limiting block rotates to a staggered position relative to the mounting hole, the positioning protrusion enters the mounting hole.

A refrigerator includes a drain assembly guiding water downward into a water container. The drain assembly includes a drain valve having a valve body, a water inlet and a drain outlet. The water inlet conducts water into, and the drain outlet conducts water out of, the valve body. A water passage between water inlet and drain outlet includes first and second side by side cavities. The drain valve includes a water valve isolating the first cavity from the second cavity or communicating the first and second cavities. The configuration of the water passage and water valve allows the height of the drain assembly to be lowered. During manufacture and assembly of the refrigerator, interference and restriction of the drain assembly upon mounting and assembly of other components are reduced. Gravity of the water valve has less impact on sensitivity of the water valve, and the drain assembly is more sensitive.

A storage system for a house entrance includes an entrance refrigerator, a first storage disposed above the entrance refrigerator, and a second storage disposed below the entrance refrigerator.

A drain harness for a device with a drain. The drain harness may define at least a portion of one or more through openings. The drain harness may include one or more electrical wirings. The drain harness may include one or more electrical components. The drain harness may be flexible or flexed between one or more configurations. The drain harness may include one or more caps and/or seal mechanisms.

A siphon has a housing with a first component, which has a first connection stub, and a second component, which has a second connection stub. An axis of one of the connection stubs extends through a free space of the other connection stub. In a sectional plane between the first and the second connection stubs, the sectional plane crossing over the axis, the siphon has the following: a first cavity, which adjoins the free space of the first connection stub, a second cavity, which on a first side of the sectional plane is separated from the first cavity by a first wall and on a second side of the sectional plane, the second side being directed towards the second connection stub, adjoins the first cavity, and a third cavity, which adjoins the free space of the second connection stub.

A refrigerator comprises: a refrigerator body (10), at the interior of which a cooling chamber (11) and at least one storage space are confined, wherein the cooling chamber (11) is arranged at the bottom of the refrigerator body (10) and below the storage space; door bodies (20) arranged on a front surface of the refrigerator body (10) to operably open and close the storage space; and an evaporator (21), which is wholly horizontally placed in the shape of a flat cube in the cooling chamber (11) and configured to provide cold energy to the storage space, wherein a bottom wall of the cooling chamber (11) below the evaporator (21) is provided with a water pan (40) to receive condensate water generated by the evaporator (21), and the bottom of the water pan (40) is provided with compensation heating wires (80).

A jumper drain for a refrigerator appliance, the jumper drain including a housing with a cavity defined therein and that is in fluid communication with a storage compartment of the refrigerator appliance. An inlet and an outlet extend from the housing and are both in fluid communication with the cavity. The outlet is disposed at a location that is offset from the inlet. A pressure equalizer opening is formed in the housing. The pressure equalizer opening is configured to provide fluid communication between the cavity and an ambient environment external to the refrigerator appliance in order to equalize a pressure differential within the refrigerator appliance.

A tool configured to assemble a drain to a household appliance wall, the drain formed by an interior tube and an exterior tube, the tool including a jaw, a housing, a spring and a guide member. The jaw is formed by a pair of arms and configured to move between a closed position, in which the jaw is configured to be inserted through an aperture formed by the household appliance wall, and an open position in which the jaw is configured to engage the interior tube. The housing houses the jaw and the spring is fixed to the housing and configured to bias the jaw towards the closed position. And the pair of arms are configured to move from the closed position to the open position as the jaw is inserted through the aperture.

A drainage assembly for an insulated structure includes a flexible body that has a plurality of flexures and defines an opening and notches that extend radially from the opening. A first drainage tube extends through the opening and includes receiving flanges disposed within the notches defined by the flexible body. A second drainage tube is in fluid communication with the first drainage tube. The second drainage tube includes engagement flanges disposed within the receiving flanges of the first drainage tube.

A drain extension assembly for an appliance that provides fluid communication between an internal storage compartment and an exterior environment via an appliance drain that collects and transfers liquid condensate from an evaporator. The drain extension assembly includes a main body with an inlet and an outlet. The inlet is configured to be secured to the appliance drain and the outlet is configured to be secured to an extension tube discharges the liquid condensate into a drain pan. A vacuum relief system provides selective fluid communication between the main body and the exterior environment. The vacuum relief system includes a pressure relief valve provided at a wall of the main body.
