Description

refrigerator

[0001] The present disclosure relates to a refrigerator, and more particularly, to a refrigerator including an electric appliance.

[0002] A refrigerator is a device that maintains food freshness by including a main body with a storage compartment and a cooling device that supplies cold air to the storage compartment. The storage compartment includes a refrigerator compartment, which is maintained at approximately 0 to 5 degrees Celsius and used to refrigerate food, and a freezer compartment, which is maintained at approximately 0 to -30 degrees Celsius and used to freeze food. The storage compartment is designed to have an open front for food entry and exit, and the front of the storage compartment is opened and closed by a door.

[0003] A refrigerator uses a compressor, condenser, expander, and evaporator to repeat the cooling cycle of compressing, condensing, expanding, and evaporating the refrigerant. A single evaporator located in the freezer can cool both the freezer and refrigerator compartments, or the freezer and refrigerator can each have their own evaporators, allowing for independent cooling.

[0004] The refrigerator body can be formed by combining an inner case and an outer case. The inner case forms the storage compartment, and the outer case forms the exterior of the refrigerator. Insulating material is placed between the inner and outer cases to insulate the storage compartment.

[0005] A refrigerator having an improved structure for supplying power to electrical components placed inside the inner case from outside the inner case is disclosed.

[0006] Additionally, a refrigerator having a case with an improved structure to simplify the manufacturing process is disclosed.

[0007] In addition, a refrigerator having a case that can be easily assembled into an interior is disclosed.

[0008] Additionally, a refrigerator having an improved structure to prevent insulation from penetrating into the interior of the inner case is disclosed.

[0009] The technical problems to be achieved in this document are not limited to the technical problems mentioned above, and other technical problems not mentioned can be clearly understood by a person having ordinary skill in the technical field to which the present invention belongs from the description below.

[0026] The term "and / or" includes any combination of a plurality of related described elements or any one of a plurality of related described elements.

[0027] Terms such as "first," "second," or "first" or "second" may be used simply to distinguish one component from another and do not qualify the components in any other respect (e.g., importance or order).

[0028] When a component (e.g., a first component) is referred to as being "coupled" or "connected" to another component (e.g., a second component), with or without the terms "functionally" or "communicatively," it means that the component can be connected to the other component directly (e.g., wired), wirelessly, or through a third component.

[0029] The terms "include" or "have" are intended to specify the presence of a feature, number, step, operation, component, part or combination thereof described in this document, but do not preclude the presence or addition of one or more other features, numbers, steps, operations, components, parts or combinations thereof.

[0030] When a component is said to be “connected,” “coupled,” “supported,” or “in contact with” another component, this includes not only cases where the components are directly connected, coupled, supported, or in contact, but also cases where the components are indirectly connected, coupled, supported, or in contact through a third component.

[0031] When we say that a component is "on" another component, this includes not only cases where the component is in contact with the other component, but also cases where there is another component between the two components.

At least one sealing fixing portion (124) protruding to both sides may be formed at the other end of the sealing plug (125). At least one sealing fixing portion (124) may be inserted into a fixing portion (126) to fix the sealing plug (125) to the case (100).

[0099] The sealing plug (125) can be formed integrally with the case (100). The sealing plug (125) can be manufactured integrally with the case (100) on the outside of the case (100). The sealing plug (125) can be easily separated from the case (100) and block the wire passage (120) after the wire (81) is accommodated in the case (100).

[0100] FIG. 9 is a drawing showing a wire fixed to a case according to one embodiment of the present disclosure.

[0101] The wire (81) may include a connector (82) formed at the end of the wire (81). The connector fixing portion (130) may fix the connector (82) to prevent the wire (81) from being pulled out of the case (100) by the foaming pressure of the insulating material (50). The connector fixing portion (130) may protrude in a second direction so that the connector (82) may be fixed in a direction different from the first direction. Due to the difference between the direction in which the connector (82) is fixed to the connector fixing portion (130) and the direction in which the base (150) extends, a portion of the wire (81) may be spaced apart from the base (150).
