[0024] The present invention will be described in detail below with reference to the embodiments shown in the accompanying drawings. However, the embodiments do not limit the present invention, and any structural, methodological, or functional changes made by those skilled in the art based on the embodiments are all within the scope of protection of the present invention.

[0025] Please refer to Figures 1 to 9 The figure shows a preferred embodiment of the refrigerator-freezer and its drawer assembly 100 of the present invention. For the sake of convenience, the side of the drawer assembly 100 close to the consumer is regarded as the front side, and the side away from the consumer is regarded as the rear side. A direction perpendicular to the front-to-back direction is defined as the lateral direction, and another direction perpendicular to the front-to-back direction is defined as the height direction.

[0026] The refrigerator-freezer of the present invention includes a drawer assembly 100, which includes at least one drawer 2 that can be inserted into or pulled out of a housing 1 of the refrigerator-freezer. The refrigerator-freezer has a housing 1 with an open front, and each drawer 2 includes a pair of side walls 21 disposed opposite each other in the transverse direction, and a front wall 23 and a rear wall 24 disposed opposite each other in the front-to-back direction.

[0027] The drawer assembly 100 further includes a slide rail assembly 3 and a support assembly 4, each of which is disposed on opposite sides of the corresponding drawer 2 in the transverse direction. The slide rail assembly 3 and the support assembly 4 on both sides of each drawer 2 together constitute a sliding mechanism for allowing the drawer 2 to slide forward and backward. Furthermore, in a set of sliding mechanisms corresponding to each drawer 2, the slide rail assembly 3 is only disposed on one side of the drawer 2 in the transverse direction, and the support assembly 4 is only disposed on the other side of the drawer 2 in the transverse direction.

[0028] For details, please refer to Figures 3 to 5 and Figures 7 to 9As shown, the slide rail assembly 3 includes an outer rail 31 fixed to the inner wall surface 12 of the cylinder 1, a first bracket 32 fixed to the outside of the drawer 2, an inner rail 34 fixed to the first bracket 32 and a fixing seat 35 fixed to the outer rail 31, and the inner rail 34 is slidably connected to the fixing seat 35.

[0029] The outer rail 31 extends in the front-to-back direction, the inner rail 34 is accommodated inside the outer rail 31 and supported by the inner rail 34 so as to be slidable back and forth, and the fixing seat 35 is sandwiched between the outer rail 31 and the inner rail 34 in the transverse direction.

[0030] The fixing seat 35 is T-shaped and includes a fixing wall 351 for fixing to the inner rear wall of the cylinder 1 and a guide arm 352 extending forward perpendicular to the fixing wall 351. The guide arm 352 is provided with a guide groove 3521 extending in the front-to-back direction. The fixing wall 351 has a snap-fit portion 3512 protruding outward in the transverse direction. The guide groove 3521 located on the front side passes through the guide arm 352 in the transverse direction.

[0031] The outer rail 31 is provided with a positioning hole 312 adjacent to the rear end thereof, and the locking portion 3512 of the fixing seat 35 protrudes into the positioning hole 312 and is locked therewith.

[0032] The inner rail 34 includes a first inner rail 341 and a second inner rail 342 that cooperate with each other. The first inner rail 341 wraps the second inner rail 342 therein. The guide arm 352 and the second inner rail 342 are arranged on both sides of the first inner rail 341 in the transverse direction. The slide rail assembly 3 also includes a guide member 36 assembled on the guide arm 352 and a connecting member 37 connecting the guide member 36 to the inner rail 34. The connecting member 37 has a protrusion 371 accommodated in the guide groove 3521 and slidable in the guide groove 3521, and a protrusion 372 protruding toward the guide member 36 and inserted into the guide member 36 and the second inner rail 342.

[0033] The fixing seat 35 is located at the rear end of the first inner rail 341 and is arranged side by side with the first inner rail 341 in the front-to-back direction. The first inner rail 341 is recessed with a receiving groove 3412 for accommodating the guide arm 352. The slide rail assembly 3 also has a fixing block 38 fixed to the rear end of the second inner rail 342. The protrusion 372 is clamped by the fixing block 38 and drives the inner rail 34 to slide back and forth.

[0034] Please refer to Figures 3 to 6As shown, the support assembly 4 includes a support bracket 41 fixed to the inner wall surface 12 of the cylinder 1, a second bracket 42 fixed to the outside of the drawer 2, and a sliding member 43 connecting the support bracket 41 and the second bracket 42, and the second bracket 42 is slidably connected to the support bracket 41.

[0035] The sliding member 43 is fixed to the distal end of the second bracket 42 . The support bracket 41 is provided with a sliding groove 412 extending in the front-to-back direction. The sliding member 43 is at least partially received in the sliding groove 412 and slides therein in the front-to-back direction.

[0036] Viewed from the front to the rear, the end surface of the support bracket 41 is L-shaped and includes a mounting wall 413 positioned against the inner wall surface 12 of the cylindrical body 1 and a connecting wall 414 perpendicular to the mounting wall 413. The chute 412 is recessed in the connecting wall 414 and formed downwardly from the top surface of the connecting wall 414. The height of the connecting wall 414 is greater than the width of the mounting wall 413 in the transverse direction, thereby forming the chute 412, which is recessed in the height direction.

[0037] The sliding member 43 includes a slider 431 and a fastener 432 detachably connected to the slider 431. The second bracket 42 has an L-shaped main body 421, an extension wall 422 protruding from the top of the main body 421 toward the cylinder 1, and a flange portion 423 bent downward from the main body 421, so that the second bracket 42 appears as a continuous step when viewed from the front end.

[0038] A pair of hooks 25 are formed on each side of the bottom of the drawer 2, wherein the pair of hooks 25 on one side are hooked into the hook holes 4212 of the main body 421, and the pair of hooks 25 on the other side are hooked into the hook holes (not shown) of the first bracket 32.

[0039] The extending wall 422 is attached to the upper side of the connecting wall 414 and covers the sliding groove 412 .

[0040] The extension wall 422 and the flange portion 423 are arranged on both sides of the main body 421 in the horizontal direction. The extension wall 422 has a socket 4221 that penetrates it along the height direction for the fastener 432 to be inserted downward. The slider 431 is located on the lower side of the extension wall 422 and is locked in the accommodating space defined by the extension wall 422 and the main body 421. Furthermore, the slider 431 is attached to the lower side of the extension wall 422, and the fastener 432 is from the upper side of the extension wall 422.

[0041] like Figure 1 and Figure 2As shown, in the present invention, the drawer assembly 100 has two drawers 2 arranged adjacent to each other in the height direction, and each of the drawers 2 is respectively provided with a slide rail assembly 3 and a support assembly 4 on both sides, and the slide rail assembly 3 on the outside of one drawer 2 and the slide rail assembly 3 on the outside of the other drawer 2 are located on different sides of the drawer assembly 100 in the transverse direction.

[0042] The refrigeration and freezing device and its drawer assembly of the present invention reduce the space occupied by the sliding mechanism and increase the usable volume of the drawer 2 by arranging a slide rail assembly 3 on one side of the drawer 2 and a support assembly 4 on the other side. It has a simple structure, low cost, and better user experience.
