A space for disposing the input member 30 that will be described below in detail may be defined between the door plate 26 and the door case 24.

The door plate 26 may be formed of a tempered glass or plastic material. A pattern 261 or color for forming the outer appearance of the door 20 may be realized on the door plate 26. For this, a back surface of the door plate 26 may be printed, or a printed film may be attached to the back surface of the door plate 26.

Here, the pattern 261 may have various shapes such as a geometric shape and a flower shape. Also, the pattern 261 may have a shape having a predetermined area. Hereinafter, the pattern 261 having the flower shape may be described as an example.

The pattern 261 formed on the door plate 26 may have various shapes. The pattern 261 may be disposed on at least central portion of a vertical height of the door 20. Also, the pattern 261 may be disposed on a position corresponding to that of the input member 30 so that the user touches the pattern 261 to manipulate the input member 30.

Here, the pattern 261 corresponding to the input member 30 may have various shapes according to a design of the refrigerator 1. The pattern 261 may have a relatively large size. For example, the pattern may have a size significantly greater than that of each of buttons used for manipulating the refrigerator 1. Thus, the input member 30 may be very easily manipulated.

The input member 30 may be electrically connected to the control unit 40 to manipulate the door opening device 13. Thus, when the input member 30 is manipulated, the door opening device 13 may be operated by the control unit 40.

The input member 30 may include a general static or piezoelectric touch module. Also, the input member 30 may be disposed on a back surface of the pattern 261 disposed on the door plate 26. Thus, the input member 30 is not exposed to the outside of the door 20. When the user pushes a portion corresponding to the input member 30 and the pattern 261 of the door plate 26, the input member may be operated.

In detail, the input member 30 is mounted on the input member mounting part 241 of the door case 24. Here, the input member mounting part 241 may have a shape corresponding to that of the pattern 261 of the door plate 26 and be disposed at a rear side of the pattern 261. Thus, when the input member 30 is mounted, the input member 30 may be disposed on a position corresponding to that of the pattern 261.

Also, the input member 30 may include first and second input members 31 and 32 for respectively manipulating the refrigerating compartment door opening device 131 and the freezing compartment door opening device 132. Each of the first and second input members 31 and 32 may define a portion of the pattern 261 and be disposed adjacent to each other.

Thus, when the opening of the refrigerating compartment door 21 is required, the user may push the pattern 261 corresponding to the first input member 31 to open the refrigerating compartment 11. Also, when the opening of the freezing compartment door 22 is required, the user may push the pattern 261 corresponding to the second input member 32 to open the freezing compartment 12.

Here, the first and second input members 31 and may be disposed on the patterns 261 disposed on positions different from each other. In this case, the first and second input members 31 and 32 may be disposed on positions at which the first and second input members 31 and 32 can be manipulated by an elbow of the user or a portion of the body of the user corresponding to the elbow.

Also, upper and lower ends of the door 20 may be rotatably mounted on the cabinet 10 by upper and lower hinge devices 14 and 15, respectively. The lower hinge device 15 may be configured to further open the door 20 when the door 20 is opened at a predetermined angle.

In detail, after the door 20 is opened at a predetermined angle by the door opening device 13, the door 20 may be further opened at an angle greater than the predetermined angle by the lower hinge device 15. Here, the lower hinge device 15 may include a torsion spring therein. Thus, the lower hinge device 15 may be rotated by an elastic restoring force to further open the door 20. Alternatively, the lower hinge device 15 may have a structure in which cam surfaces corresponding to each other are relatively moved by a load of the door 20 to open the door 20.

Hereinafter, operations of the refrigerator including the above-described components according to an embodiment will be described.

In a state where the refrigerator 1 is normally operated, the door handle 23 may be pulled to open the door 20 and receive the food, thereby receiving foods in the refrigerator 1.

When it is difficult to open the door 20 because the user holds a food using both hands, the user may push the input member 30 using the user's body, particularly, the user's elbow.

Since the input member 30 is disposed on the door 20 at a height corresponding to the approximately central portion of the vertical height of the cabinet 10, the input member 30 may be easily pushed using the user's body. Specifically, in case where the user is an adult, when the input member 30 disposed at a height of about 1 m from the ground is manipulated, the input member 30 may be easily pushed using the user's elbow.

The input member 30 may be disposed on a position corresponding to that of the pattern 261 disposed on the door plate 26 and have the same size as that of the pattern 261. Thus, the user may push the pattern 261 to manipulate the input member 30. Here, the input member 30 is not exposed to the outside. Thus, the user may touch the pattern 261 to open the door 20.

Also, the input member 30 may include the first and second input members 31 and 32 for respectively opening the refrigerating compartment door 21 and the freezing compartment door 22. In this case, the user may push a portion of the pattern 261 corresponding to each of the first and second input members 31 and 32 to open the corresponding door 20. Here, when the pattern 261 has a large size, the first and second input members 31 and 32 may be disposed on one pattern 261. In this case, the user may push a portion corresponding to the one pattern 261 to open the door 20.

A refrigerator according to various embodiments except the above-described embodiment may be realized. Hereinafter, a refrigerator will be described according to another embodiment.

In the refrigerator according to another embodiment, an input member has a shape corresponding to that of a pattern of a door and has the same material as that of an outer surface of the door.

Thus, the refrigerator according to another embodiment may be equal to the refrigerator according to the foregoing embodiment except for a portion of the door and the input member, and thus detailed descriptions thereof will be omitted.

Here, the push part 41 may have a shape corresponding to that of the pattern part 262 and have the same material as that of the door plate 26. Thus, when the input member 40 is mounted, the push part 41 may constitute a portion of the door plate 26. As a result, when viewed from the outside, the push part 41 may be integrated with the door plate 26.

Also, the push part 41 may be moved in front and rear directions by the guide of the input member mounting part 241 on which the input member 40 is mounted. Thus, when the input member 40 is pushed, the push part 41 may be guided in the front and rear direction by the input member mounting part 241.

The switch 42 may be disposed on a position at which it is pushed when the push part 41 is pushed. Here, even though any portion of the push part 41 is pushed, the switch should be pushed. Two switches 42 may be respectively disposed to manipulate the refrigerating compartment door opening device 131 and the freezing compartment door opening device 132. Also, the push part 41 may be divided into two sections. Here, the two push parts 41 may be divided also by the pattern 261.

The push part 41 may be returned to its original position after being pushed by elasticity of the switch 42. Thus, an elastic member for returning the push part 41 may be disposed at a rear side of the push part 41. Thus, the push part 41 may be flush with the door plate 26 without manipulating the push part 41 to visually realize sense of unity with the door plate.

A refrigerator according to various embodiments except the above-described embodiments may be realized. Hereinafter, a refrigerator will be described according to another embodiment.

In the refrigerator according to another embodiment, both ends of an input unit contact both ends of a door.
