The reinforcing member 130 is provided to strengthen the rigidity of the handle lever 110, and when the handle lever 110 itself is formed of metal or engineering plastic, the reinforcing member 130 may not be used.

[0100] The door opening device 100 may include a sliding member 140, and the sliding member 140 is assembled to the door bracket 60 to perform a straight linear motion. The sliding member 140 may be disposed between the handle lever 110 and the pusher 150. The sliding member 140 may be disposed at the rear of the handle lever 110. The sliding member 140 may be caused to perform a straight linear motion in the up-down direction by the handle lever 110. That is, when the handle lever 110 is rotated, the sliding member 140 may be caused to perform a straight linear motion in the up-down direction by the handle lever 110, and when the sliding member 140 performs a straight linear motion in the up-down direction, the pusher 150 may be caused to perform a straight linear motion by the sliding member 140, thereby pushing the main body ( Figure 1 of 10).

[0101] The slider 140 may include a guide protrusion 141 that guides the slider 140 to move along the first guide rail 63a formed on the door bracket 60. The guide protrusion 141 may be formed on both sides of the slider 140. When the guide protrusion 141 moves along the first guide rail 63a, the slider 140 may perform a straight linear motion in the up and down directions.

[0102] The slider 140 may include a sliding surface 143 that may contact the handle lever 110. The sliding surface 143 may be a contact surface that may contact the pressing portion 127 of the handle lever 110. The sliding surface 143 may be provided at the lower end of the slider 140. The sliding surface 143 may be formed obliquely so that the pressing portion 127 moves in a slidable manner. When the handle lever 110 is rotated, the pressing portion 127 may move in a slidable manner along the sliding surface 143 to move the slider 140 upward (see FIG. 1 ). Fig.15 ).

[0103] The slider 140 may include a first inclined surface 145 that may contact the pusher 150. The first inclined surface 145 may be a contact surface that may contact the pusher 150. The first inclined surface 145 may be provided at an upper end of the slider 140. The first inclined surface 145 may be formed obliquely so that the pusher 150 slidably moves along the first inclined surface 145. When the slider 140 performs an upward straight linear motion by the handle lever 110, the pusher 150 may move along the first inclined surface 145 while performing a backward straight linear motion (see Fig.15 ).

[0104] The sliding member 140 may include an anti-separation protrusion 147 for preventing the handle lever 110 assembled to the door bracket 60 from being separated. The anti-separation protrusion 147 may be provided on one side of the lower end of the sliding member 140. The anti-separation protrusion 147 may prevent the handle lever 110 assembled to the handle lever assembling portion 61 of the door bracket 60 from being separated in a direction opposite to the direction along which the handle lever 110 is assembled.

[0105] The door opening device 100 may include a pusher 150, which is assembled to the door bracket 60 to perform a straight linear motion. When the user presses and rotates the handle lever 110, the slider 140 performs an upward straight linear motion through the handle lever 110, and the slider 140 moving upward may move the pusher 150 backward, thereby pushing the main body 10. When the pusher 150 pushes the main body 10, the drawer door 40 may be opened (see Figure 1 ).

[0106] The pusher 150 may include a second inclined surface 151 that may contact the slider 140. The second inclined surface 151 may be provided on a front end of the pusher 150. The second inclined surface 151 may be a contact surface that may contact the slider 140. The second inclined surface 151 may contact the first inclined surface 145 of the slider 140. The second inclined surface 151 may be obliquely formed to correspond to the first inclined surface 145. When the slider 140 performs an upward straight linear motion through the handle lever 110, as the second inclined surface 151 slides along the first inclined surface 145, the pusher 150 may perform a backward straight linear motion. That is, the pusher 150 may perform a straight linear motion in a direction toward the body 10 (see Fig.15 ).

[0107] The pusher 150 may include a push portion 153 that performs a rearward straight linear motion to push the main body 10. The push portion 153 may be disposed at a rear end of the pusher 150. When the pusher 150 performs a rearward straight linear motion through an opening 65b formed in the door bracket 60 by the slide member 140, the pusher 150 may push the main body 10. The opening 65b may be disposed at a position corresponding to the second opening portion 55 of the door cover 50. Therefore, the pusher 150 may push the main body 10 through the opening 65b of the door bracket 60 and the second opening portion 55 of the door cover 50 (see Figure 3 and Fig.15 ).

[0108] The door opening device 100 may include an elastic member 160 having one end supported by the handle lever 110 and the other end supported by the door bracket 60. The elastic member 160 may be provided as a torsion spring. Although the elastic member 160 is illustrated as provided as a torsion spring in the drawings, it is not limited thereto. That is, the elastic member 160 may be provided as a coil spring. The elastic member 160 may be assembled to one of the plurality of rotation shafts 128 formed in the bracket 120 of the handle lever 110. One end of the elastic member 160 assembled to one of the plurality of rotation shafts 128 may be supported on an elastic member support groove 129 formed in the bracket 120. That is, the elastic member 160 may be provided between the handle lever 110 and the door bracket 60. When the handle lever 110 is rotated when the user presses the handle lever 110, the handle lever 110 may compress the elastic member 160. When the force applied to the handle lever 110 is removed as the elastic member 160 is compressed, the handle lever 110 may rotate in a direction opposite to the force applied to the handle lever 110 due to the compression force of the elastic member 160. That is, before the force is applied to the handle lever 110, the handle lever 110 may rotate to return to its original position.

[0109] In the case where the refrigerator has a structure that allows the front panel 43 to be replaced of the drawer-type door 40 to be replaced, the thickness of the insulation of the drawer-type door 40 may be reduced due to the presence of a structure for assembling the front panel 43. That is, the upper part of the drawer-type door 40 inevitably has a small insulation thickness due to the handle recess 51, and the insulation thickness may be further reduced due to the presence of a structure for assembling the front panel 43. As described above, when the sliding member 140 for transmitting the rotational force of the handle lever 110 to the pusher 150 in the door opening device 100 is configured to perform a straight linear motion in the up-down direction, the door opening device 100 can be made to have a reduced volume in the front-to-back direction. That is, when the length of the door opening device 100 in the front-to-back direction is reduced, the space including the door opening device 100 can be reduced accordingly. Therefore, the width of the handle recess 51 in the front-to-back direction can be shortened, and the insulation thickness of the drawer-type door 40 can be minimized.

[0110] In addition, as described above, when the sliding member 140 for transmitting the rotational force of the handle lever 110 to the pusher 150 in the door opening device 100 is configured to perform straight linear motion in the up-down direction, the space occupied by the sliding member 140 is reduced, which can provide a larger rotation range for the handle lever 110. When the rotation range of the handle lever 110 increases, the moving distance of the pusher 150 also increases. Therefore, the drawer-type door 40 can be opened more easily by the door opening device 100.

[0116] After the handle lever 110 is assembled to the door bracket 60, as shown in FIG. Fig.10 As shown, the slider 140 may be assembled to the door bracket 60. The slider 140 may be assembled to the slider assembly part 63 of the door bracket 60 to perform a straight linear motion in the up and down directions. The slider 140 may be assembled to perform a straight linear motion in the up and down directions when the guide protrusion 141 is guided by the first guide rail 63a of the slider assembly part 63.

[0117] When the sliding member 140 is assembled to the door bracket 60, as shown in FIG. Fig.10 As shown, the handle lever 110 may be prevented from being separated by the anti-separation protrusion 147 of the slider 140.

[0119] Fig.13 is a view illustrating a state in which a door bracket assembled with a door opening device according to multiple embodiments of the present disclosure is assembled to a lower end of a door cover.

[0120] refer to Fig.13 , the door bracket 60 assembled with the door opening device 100 may be assembled to the lower end of the door cover 50. The door bracket 60 may be assembled to the central portion of the lower end of the door cover 50. The door bracket 60 may be assembled to the lower end of the handle recess portion 51 of the door cover 50. Since the door bracket 60 is assembled to the lower end of the handle recess portion 51, the door opening device 100 may be prevented from being exposed to the outside. Since the exposure of the door opening device 100 is prevented, when viewed from the front of the refrigerator, the drawer-type door 40 for opening and closing the lower compartment 25 may have the same appearance as the drawer-type door 40 for opening and closing the middle compartment 23 without the door opening device 100. This configuration provides a consistent feel to the drawer-type door 40 for opening and closing the middle compartment 23 and the drawer-type door 40 for opening and closing the lower compartment 25, thereby improving the appearance (see Figure 1 ).

[0121] In order to couple the door bracket 60 to the door cover 50, the door bracket 60 may be provided with a first assembling hole 67.

In this case, the pushing portion 153 of the pusher 150 may be in a state of not pushing the main body 10. That is, the handle lever 110 may be in a state where the handle lever 110 is moved by the elastic member ( Fig. 9 The state in which the elastic force 160) is maximally rotated clockwise around the plurality of rotation axes 128.

[0126] refer to Fig.17 , when the user presses the handle lever 110, the handle lever 110 may rotate counterclockwise about the plurality of rotation axes 128. When the handle lever 110 rotates counterclockwise about the plurality of rotation axes 128, the pressing portion 127 of the handle lever 110 slidably moves along the sliding surface 143 of the slider 140, so that the slider 140 performs an upward straight linear motion. When the slider 140 performs an upward straight linear motion, the second inclined surface 151 of the pusher 150 contacting the first inclined surface 145 of the slider 140 may move along the first inclined surface 145, and thus the pusher 150 may perform a backward straight linear motion.

[0127] refer to Figures 18 to 19 When the user fully presses the handle lever 110, the handle lever 110 may rotate counterclockwise about the plurality of rotation axes 128. When the handle lever 110 rotates counterclockwise about the plurality of rotation axes 128, the pressing portion 127 of the handle lever 110 slidably moves along the sliding surface 143 of the slider 140 until the end of the sliding surface 143, so that the slider 140 performs an upward straight linear motion.

[0128] When the slide 140 performs an upward straight linear motion, the second inclined surface 151 of the pusher 150 can be slidably moved along the first inclined surface 145 of the slide 140, so that the pusher 150 can perform a straight linear motion in a direction toward the main body 10. When the main body 10 is pushed by the pusher 150, the drawer door 40 can move forward and open. That is, the drawer door 40 can move in a direction away from the main body 10 and open. In this case, the elastic member ( Fig. 9 160 ) in the handle bar 110 may be in a state of being compressed.

[0129] When the user removes the force pressing the handle lever 110, the handle lever 110 can be released by the compressed elastic member ( Fig. 9 The handle lever 110 rotates clockwise around the plurality of rotation axes 128 due to the compression force of 160 in FIG. When the handle lever 110 rotates clockwise around the plurality of rotation axes 128, the handle lever 110 may return to its initial position, such as Fig.15 As shown, the slider 140 and the pusher 150 can also return to their original positions together with the handle lever 110.

[0130] Fig. 20 is a view illustrating a state in which a door opening device provided with two pushers according to various embodiments of the present disclosure is assembled to a drawer-type door.
