The cabinet 1 includes an inner casing 11, an outer casing 12, and a thermal insulation space located between the inner casing 11 and the outer casing 12 and filled with a thermal insulation material 5, to form a pair of thermal insulation walls 13 disposed opposite to each other.

(13) The thermal insulation walls 13 include recesses 14 formed in the inner casing 11 and opened forward. The inner casing 11 has a pair of opposite side walls, and a top wall and a bottom wall connected to the side walls.

(14) The storage compartment 7 has an opening 17 opened forward, and a recess 14 is opened facing the opening 17. The recess 14 is provided in the side wall close to the opening 17.

(15) The refrigerator 100 further includes a beam 2 bridging the pair of thermal insulation walls 13. A front surface of the beam 2 and a front panel of the cabinet 1 are roughly in the same plane.

(16) As shown in FIG. 3, the beam 2 includes insert portions 21 disposed on two ends and respectively inserted into the corresponding recesses 14 and a body portion 24 connecting the two insert portions 21. Each of the insert portions 21 is disposed in a corresponding end of the beam 2. A length of the body portion 24 is roughly equal to a transverse width of the storage compartment 7 on a front end.

(17) A shape of the recess 14 matches a shape of the insert portion 21.

(18) As shown in FIG. 1, the refrigerator 100 further includes a door 8 for opening or closing the opening 17. The door is hingedly connected to a front side of the cabinet 1. In this embodiment, the refrigerator 100 further includes a hinge 25 fixed on the beam 2. The door 8 is connected to the hinge 25. Therefore, the beam 2 bears a partial weight of the door 8.

(19) As shown in FIG. 4, the beam 2 includes an accommodating cavity 26, a housing 27 defining the accommodating cavity 26, and a beam thermal insulation material 6 located in the accommodating cavity 26. In this embodiment, the beam thermal insulation material 6 is formed by injecting a foaming agent into the accommodating cavity. In an alternative implementation, a pre-foamed thermal insulation part may be filled into the accommodating cavity.

(20) As shown in FIG. 3, two ends of the beam 2 respectively include a first fixing portion 22 and a second fixing portion 23 that are distributed in a spaced apart manner in a front-back direction and that are configured to be coupled to the refrigerator 100. The beam 2 is mounted at different positions of the cabinet 1 by the first fixing portion 22 and the second fixing portion 23. In an embodiment, as shown in FIG. 2, the first fixing portion 22 is connected to the inner casing 11, and the second fixing portion 23 is connected to the outer casing 12. Therefore, the beam 2 is respectively fixed to the inner casing 11 and the outer casing 12, so that the beam 2 may be connected to the cabinet 1, thereby reducing a possibility that the beam 2 turns over when bearing a weight of the door 8.

(21) The refrigerator 100 further includes a first fixing mechanism 3, and the beam 2 is fixed into the inner casing 11 by a first fixing structure. The first fixing mechanism 3 is at least partially located in the recess 14 and fixes the insert portion 21 to the thermal insulation wall 13.

(22) The insert portion 21 is connected to one of the walls in which the recesses 14 are formed.

(23) The first fixing mechanism 3 is configured to fix a rear portion of the insert portion 21 to the thermal insulation wall 13. Specifically, as shown in FIG. 2 and FIG. 6, the recess 14 has a rear wall 15 facing the opening 17. The rear portion of the insert portion 21 is face-to-face with the rear wall 15. The insert portion 21 is fixed to the rear wall 15 by the first fixing mechanism 3.

(24) As shown in FIG. 6, the inner casing 11 includes a first through hole 16 in communication with the recess 14. In an embodiment, the first through hole 16 is provided in the rear wall 15.

(25) As shown in FIG. 2, the first fixing mechanism 3 includes a fastener 37. The fastener 37 passes through the first through hole 16 and is connected to the insert portion 21, so that the insert portion 21 is fixed to the rear wall 15. In this embodiment, the fastener 37 passes through the first through hole 16 from a side of the inner casing 11, which side faces the thermal insulation space, and is connected to the insert portion 21.

(26) In an embodiment, the fastener 37 includes a screw, in particular the fastener is embodied as a screw. The screw passes through the first through hole 16 to fix the insert portion 21 to the rear wall 15.

(27) The first fixing mechanism 3 further includes a first reinforcing member 31 connected to the inner casing 11 and facing a side of the thermal insulation material 5. The first reinforcing member 31 is located in the thermal insulation space. When the refrigerator 100 is foaming, the first reinforcing member 31 is coated by the thermal insulation material 5, thereby improving strength of the first reinforcing member 31, and further improving the mounting stability and strength of the beam 2, and improving a weight capacity of the beam 2.

(28) As shown in FIG. 7, the first reinforcing member 31 includes a first reinforcing portion 32 attached to the rear wall 15 and a second reinforcing portion 33 coupled to the first reinforcing portion 32 and bent backward. In an embodiment, the first reinforcing member 31 is an L shape and the first reinforcing portion 32 is perpendicular to the second reinforcing portion 33.

(29) As shown in FIG. 9 and FIG. 10, the first reinforcing portion 32 extends along the rear wall 15. The second reinforcing portion 33 extends along the inner casing 11 and is distanced from the inner casing 11. The thermal insulation material 5 is disposed between the inner casing 11 and the second reinforcing portion 33, which is beneficial to improving the strength of the first reinforcing member 31.

(30) As shown in FIG. 7, the first reinforcing member 31 is provided with at least one second through hole 34, and the second through hole 34 is configured to allow the thermal insulation material 5 to pass through. Specifically, the first reinforcing portion 32 and/or the second reinforcing portion 33 are/is provided with at least one second through hole 34.

(31) In an embodiment, as shown in FIG. 7, the second reinforcing portion 33 is provided with a plurality of second through holes 34, and the first reinforcing portion 32 is also provided with at least one second through hole 34. During foaming, the thermal insulation material 5 may pass through the second through hole 34. The spacing between the second reinforcing portion 33 and the inner casing 11 is filled up with the thermal insulation material 5, and the second through hole 34 is also filled up with the thermal insulation material 5.

(32) In this case, a capacity of grabbing a foaming material of the first reinforcing member 31 can be improved, so that the first reinforcing portion 32 and the second reinforcing portion 33 may grab more foaming material in a foaming process, thereby further improving the strength of the first reinforcing member 31, improving the weight capacity of the beam 2, and reducing the possibility that the beam turns over when bearing the weight of the door 8.

(33) As shown in FIG. 2, the first fixing mechanism 3 further includes a second reinforcing member 35 corresponding to the first reinforcing member 31. The second reinforcing member 35 is disposed in the insert portion 21 and is bonded to the thermal insulation material 5 of the beam 2.

(34) Specifically, the second reinforcing member 35 is disposed in the accommodating cavity 26. The beam thermal insulation material 6 is provided in the accommodating cavity 26. The second reinforcing member 35 is bonded to the beam thermal insulation material 6 in the foaming process. As shown in FIG. 8, the second reinforcing member 35 includes a first flange 36 formed by bending, enabling the second reinforcing member 35 to grab more foaming liquid in the foaming process, thereby improving strength of the second reinforcing member 35.

(35) As shown in FIG. 2 and FIG. 4, the second reinforcing member 35 is disposed along a wall of the housing 27 and corresponds to the first reinforcing member 31. A body portion of the second reinforcing member 35 is disposed along a rear wall of the housing, and the first flange 36 of the second reinforcing member is provided along a side wall of the housing, which is beneficial to improving the strength of the second reinforcing member 35.

(36) The first reinforcing member 31 and the second reinforcing member 35 are respectively provided with through holes through which the fastener 37 passes and that correspond to the first through hole 16. The fastener 37 passes through the first reinforcing member 31, the first through hole 16, and the second reinforcing member 35, to fix the first fixing portion of the insert portion 21 to the rear wall 15 of the recess 14.

(37) The refrigerator 100 further includes a second fixing mechanism 4. The second fixing mechanism 4 is located outside the recess 14 and fixes the beam 2 to the outer casing 12. Specifically, the outer casing 12 has a second flange 18 formed by bending toward the storage compartment 7. The second fixing portion 23 is fixed to the second flange 18 by the second fixing mechanism 4.

(38) As shown in FIG. 2, the first fixing mechanism 3 and the second fixing mechanism 4 are distanced from each other along a depth direction of the inner casing 11 and/or along a length direction of the beam 2. Therefore, the beam 2 is firmly mounted to the cabinet 1, thereby improving the stability of the beam 2.

(39) Various embodiments illustrated with reference to FIG. 1 to FIG. 10 may be combined with each other in any given manner to realize the advantage of the present invention. In addition, the present invention is not limited to the shown embodiments. Usually, apart from the shown means, other means can also be used as long as the means can also achieve the same effect.
