The pair of push rods 111 and 112 may be movably coupled to the pair of movement guides 103 and 104, respectively, and may move forward and backward along with the movement guides 103 and 104. The pair of movement guides 103 and 104 may be arranged parallel to each other.

The drive motor 105 may be a motor capable of forward and reverse driving. The drive motor 105 may include a DC stepper motor. A motor gear 106 may be provided on a motor shaft of the drive motor 105 to rotate together with the motor shaft. A rotational force of the motor gear 106 may be transmitted to a pair of pinion gears 108 and 109 through the transmission gear assembly 107.

Rack gears 113 and 114 engaged with the pinion gears 108 and 109 may be provided on the push rods 111 and 112. A rotational motion of the pinion gears 108 and 109 may be converted into a linear motion of the rack gears 113 and 114.

A first rack gear 113 may be engaged with the first pinion gear 108 to allow the first push rod 111 to move forward when the first pinion gear 108 rotates counterclockwise, and to allow the first push rod 111 to move backward when the first pinion gear 108 rotates clockwise.

A second rack gear 114 may be engaged with the second pinion gear 109 to allow the second push rod 112 to move backward when the second pinion gear 109 rotates counterclockwise, and to allow the second push rod 112 to move forward when the second pinion gear 109 rotates clockwise.

As described above, the first push rod 111 and the second push rod 112 may move at the same speed in opposite directions, and thus when a position of one of the first push rod 111 and the second push rod 112 is detected, a position of the other of the first push rod 111 and the second push rod 112 may be detected. Accordingly, it may be sufficient that the position detection device 130 and the magnet 120 are configured to detect the position of one of the plurality of push rods 111 and 112.

The door opening device 100 may open the first door 21 or the second door 22 according to the driving direction of the drive motor 105. For example, when the drive motor 105 rotates in a forward direction (e.g., counterclockwise when viewed from above), the first push rod 111 of the door opening device 100 may move forward to open the first door 21. When the drive motor 105 rotates in a reverse direction (e.g., clockwise when viewed from above), the second push rod 112 of the door opening device 100 may move forward to open the second door 22.

The driving direction of the drive motor 105 may be determined according to manipulation of the switch modules 70 and 270. For example, when the first switch module 70 is operated, the drive motor 105 may be driven in the forward direction to allow the first door 21 to be opened. When the second switch module 270 is operated, the drive motor 105 may be driven in the reverse direction to allow the second door 22 to be opened.

The doors 21 and 22 and the switch modules 70 and 270 according to an embodiment of the disclosure will be described with reference to FIGS. 10 to 20. Because configurations of the first door 21 and the second door 22 are almost identical, the first door 21 will be described and a description of the second door 22 will be omitted below. In addition, because configurations of the first switch module 70 and the second switch module 270 are the same or almost identical, the first switch module 70 will be described and a description of the second switch module 270 will be omitted below. Descriptions of the first door 21 and the first switch module 70 may be equally applied to the second door 22 and the second switch module 270.

The door 21 may include a door front member 40 forming the front surface of the door 21, a door side member 43 forming the side surface of the door 21, and a door rear member 49 forming the rear surface of the door 21.

According to an embodiment, the door front member 40 and the door side member 43 may be integrally formed with each other. For example, the door front member 40 and the door side member 43 may be formed by bending a single metal plate. A connection between the door front member 40 and the door side member 43 may be formed through a hemming process. Through the hemming process, an end of the door front member 40 and an end of the door side member 43 may be formed to substantially contact each other. A holder mounting groove, to which a holder for coupling with the front panel 31 is mounted, may be formed on the left and right edges of the door front member 40.

According to an embodiment, the door front member 40 and the door side member 43 may be formed separately from each other. The door front member 40 and the door side member 43 may be coupled to each other.

A handle opening 44 and a switch opening 45 may be formed in the door side member 43 (refer to FIG. 12). According to an embodiment, the handle opening 44 and the switch opening 45 may be formed separately and spaced apart from each other. The handle opening 44 may be formed larger than the switch opening 45. However, the size of the handle opening 44 and the switch opening 45 is not limited thereto. The handle opening 44 may be formed behind the switch opening 45.

According to an embodiment, the handle opening 44 and the switch opening 45 may be formed to be connected to each other.

The door 21 may include a side cap 60 coupled to an inner surface of the door side member 43. The side cap 60 may be coupled to the door side member 43 to cover the handle opening 44 and the switch opening 45. Because the side cap 60 is coupled to the inner surface of the door side member 43, the foaming solution may not leak through the handle opening 44 and the switch opening 45 when the insulating material is foamed in the inner space of the door 21.

The side cap 60 may be injection molded of a plastic material. Because the side cap 60 is injection molded from a plastic material, various shapes may be easily formed on the side cap 60. For example, the handle 61 may be recessed in the side cap 60. In addition, a switch mounting space 62 in which the switch module 70 is mounted may be formed in the side cap 60.

The handle 61 may be formed in a size and shape substantially corresponding to the handle opening 44. The handle 61 may be accessible through the handle opening 44. The switch mounting space 62 may be formed to have a size and shape substantially corresponding to the switch opening 45.

A coupling structure for coupling with the door side member 43 may be formed in the side cap 60. The side cap 60 may include a side cap groove 63 and a side cap protrusion 64 for coupling with the door side member 43. The side cap groove 63 may be formed around the handle 61.

The side cap groove 63 may be coupled to a bending member 46 of the door side member 43. The door side member 43 may include the bending member 46 formed by bending an edge of the handle opening 44 toward the inside of the door 21 (refer to FIGS. 12 and 15). The bending member 46 may be inserted into the side cap groove 63. As the bending member 46 is inserted into the side cap groove 63, the door side member 43 and the side cap 60 may be coupled.

In a state in which the bending member 46 is inserted into the side cap groove 63, the side cap protrusion 64 may be coupled to a bending member hole 47 (refer to FIG. 12). The bending member hole 47 may be formed in the bending member 46. As the side cap protrusion 64 is inserted into the bending member hole 47, the door side member 43 and the side cap 60 may be coupled.

Due to this configuration, the side cap 60 formed of a plastic and the door side member 43 formed of a metal may be easily coupled.

The door rear member 49 may be coupled to the door side member 43. The door gasket 27 (refer to FIG. 2) may be provided at an edge portion of the door rear member 49. The door rear member 49 may include a dyke protruding backward, and the door shelf 26 (refer to FIG. 2) may be mounted on the dyke.

When the switch module 70 is mounted in the switch mounting space 62, at least a portion of the switch module 70 may protrude outward from the door side member 43.

While the switch module 70 is mounted in the switch mounting space 62, the switch module 70 may be fixed through a fastening member S (refer to FIGS. 13, 14, and 17). The fastening member S may pass through the door front member 40 and be coupled to the switch module 70. Accordingly, the switch module 70 may be fixed to the rear surface of the door front member 40. The fastening member S may include various mechanical coupling elements such as screws, bolts, nails, and pins.

A through hole 41 may be formed in the door front member 40 to allow the fastening member S to pass therethrough. A fastening hole 88 to which the fastening member S is fastened may be formed in the switch module 70.

The switch module 70 may be coupled to the door side member 43. One end 48 around the switch opening 45 of the door side member 43 may be coupled to the switch module 70 (refer to FIG. 16). The switch module 70 may include an end coupler 94 coupled to the end 48 of the door side member 43. The end coupler 94 may be formed in a groove or hole shape. The end 48 of the door side member 43 may be inserted into the end coupler 94.

In a state in which the end 48 of the door side member 43 is inserted into the end coupler 94, the above-described fastening member S may be coupled to the switch module 70.

Due to this configuration, the switch module 70 may be conveniently mounted on the door 21. In addition, because the switch module 70 is mounted on the door side member 43 of the door 21, the aesthetics of the door front member 40 may not be reduced.

The switch module 70 may receive a user input for operating the door opening device 100. The switch module 70 may receive a user input by a user's touch. That is, when a user touches the switch module 70, the switch module 70 may generate a signal for operating the door opening device 100.

When the switch module 70 is mounted in the switch mounting space 62, the touch surface 95 may form a part of the side surface of the door 21. The touch surface 95 may be located substantially directly in front of the handle 61.

When the switch module 70 is mounted in the switch mounting space 62, the touch surface 95 may protrude from the door side member 43. The touch surface 95 may include a curved surface. The touch surface 95 may include the curved surface in which an amount of protrusion P from the door side member 43 is reduced from a front end 96 of the touch surface 95 to a rear end 97 of the touch surface 95. With this configuration, when a user holds the handle 61 with his/her hand, the handle 61 may provide an excellent grip feeling and thus the user can comfortably hold the handle 61.

When a user's hand touches the touch surface 95, static electricity may be generated, and the generated static electricity may be transmitted to the circuit board 71 through the second switch case 91, the first switch case 81, and the transfer member 73.

FIG. 21 is a view illustrating an operation of coupling the front panel to the door according to an embodiment of the disclosure, particularly, a view illustrating an operation of coupling a lower end of the front panel to a lower cap. FIG. 22 is a view illustrating the operation of coupling the front panel to the door according to an embodiment of the disclosure, particularly, a view illustrating a state in which the front panel is rotated with respect to the lower cap following the operation of FIG. 21. FIG. 23 is a view illustrating the operation of coupling the front panel to the door according to an embodiment of the disclosure, particularly, a view illustrating a state in which a fixer is coupled to an upper end of the front panel and an upper cap following the operation of FIG. 22.

The front panel will be described with reference to FIGS. 21 to 23.

According to an embodiment, the refrigerator 1 may include the front panels 31 and 32 detachably coupled to front surfaces of the doors 21 and 22. Because the front panel 31 and the front panel 32 include the same or mostly similar configurations, only the front panel 31 will be described.

That is, the front panel 31 may be moved from an inclined state to an upright state by rotating with respect to the lower cap protrusion 59 in a state in which the lower cap protrusion 59 is inserted into the lower trim groove 39. Alternatively, the front panel 31 may be moved from the upright state to the inclined state in the same way.

When the front panel 31 is coupled to the door 21, the upper trim 34 may be covered by the upper cap 50. Accordingly, the upper trim 34 may not be exposed to the outside.

The upper trim 34 may include a fixer coupler 35. The fixer coupler 35 may be inserted into the upper cap 50. For example, the fixer coupler 35 may be inserted into a trim receiving space 52 of the upper cap 50. A trim opening 53 may be formed on the front side of the trim receiving space 52 of the upper cap 50. The fixer coupler 35 of the upper trim 34 may be inserted into the trim receiving space 52 of the upper cap 50 through the trim opening 53 of the upper cap 50.

The fixer coupler 35 may include a fixer coupling hole 36. The fixer coupling hole 36 may be formed to penetrate the fixer coupler 35 in an up and down direction. A fixer 55 may be coupled to the upper trim 34. For example, the fixer 55 may be coupled to the fixer coupling hole 36 of the upper trim 34. The fixer 55 may be inserted into the fixer coupling hole 36. A fixer opening 54 may be formed on an upper side of the trim receiving space 52 of the upper cap 50. At least a portion of the fixer 55 may be inserted into the trim receiving space 52 of the upper cap 50 through the fixer opening 54 of the upper cap 50.

When the fixer coupler 35 of the upper trim 34 is inserted into the trim receiving space 52 of the upper cap 50, the fixer 55 may be inserted into the trim receiving space 52 of the upper cap 50 through the fixer opening 54 of the upper cap 50, and then the fixer 55 may be coupled to the fixer coupler 35 of the upper trim 34. With this configuration, the front panel 31 may be detachably coupled to the door 21.

The front panel 31 may include a magnet 37 for coupling with the door 21. The magnet 37 may be provided to extend vertically on left and right edge portions of the panel body 33. With magnetic force, the magnet 37 may be in close contact with the door front member 40 formed of a metal.

The lower cap 56 may form a lower surface of the door 21. The lower cap 56 may include a lower cap body 57. The lower cap 56 may include a lower cap support 58 protruding forward from a lower portion of the lower cap body 57. The lower cap support 58 may be formed to protrude forward from the door front member 40. The lower cap support 58 may support the lower end of the front panel 31. The lower cap 56 may include the lower cap protrusion 59 protruding upward from the lower cap support 58.

The upper cap 50 may form the upper surface of the door 21. The upper cap 50 may include an upper cap body 51. The upper cap 50 may include the trim receiving space 52. The upper cap 50 may include the trim opening 53 formed on the front side of the trim receiving space 52 to allow the upper trim 34 of the front panel 31 to be inserted into the trim receiving space 52. The upper cap 50 may include the fixer opening 54 formed on the upper side of the trim receiving space 52 to allow the fixer 55 to be inserted into the trim receiving space 52. The fixer opening 54 may be formed at a position corresponding to the fixer coupling hole 36 of the upper trim 34.

As described above, the switch module 70 is provided on the door side member 43 of the door 21, and thus when the front panel 31 is coupled to the front surface of the door 21, the switch module 70 may not be covered by the front panel 31. That is, the switch module 70 may be easily touched when a user holds the handle 61 regardless of whether the front panel 31 is coupled or not.

On the other hand, when the front panel 31 is coupled to the front surface of the door 21, the fastening member S provided to couple the switch module 70 to the door front member 40 may be covered by the front panel 31 and thus not be exposed to the outside (refer to FIG. 17). Therefore, when the front panel 31 is coupled to the door 21, the fastening member S may not be exposed, and thus the aesthetics may be further improved and the fastening member S may be prevented from being loosened.
