Description

Technical Field

[0001] The invention relates to the field of refrigeration equipment, and in particular to a refrigeration equipment with a drawer. Background Art

[0002] As the number of family members increases, the demand for large-capacity refrigerators also increases. The larger the capacity of a refrigerator, the larger the capacity of its single drawer, and the more items it can accommodate, resulting in a greater load on the mechanism supporting the drawer.

[0003] Currently, slide rails are commonly used in the industry to support drawers. As the load capacity of the slide rails increases, their costs will also increase. This cost change is not a linear change, but an exponential change. Therefore, the cost of large-volume refrigerators is also higher. Summary of the invention

[0004] The object of the present invention is to provide a refrigeration device for solving the above-mentioned problem.

[0005] To achieve one of the above-mentioned purposes of the invention, the present invention provides a refrigeration device, comprising a box body, a drawer slidably connected to the box body along the front-to-back direction, and a slide rail assembly arranged between the box body and the drawer. The refrigeration device also includes an auxiliary support mechanism connected to the box body. During the process of the drawer being pulled along the front-to-back direction, the auxiliary support mechanism provides an upward supporting force to the drawer.

[0006] As a further improvement of the present invention, when the drawer is pulled out to a preset position, the auxiliary support mechanism is in a supporting state; when the drawer is fully retracted into the box, the auxiliary support mechanism is in a retracted state.

[0007] As a further improvement of the present invention, the auxiliary support mechanism includes a support rod, and the support rod includes a first end rotatably connected to the bottom wall of the box body and a second end for supporting the drawer.

[0008] As a further improvement of the present invention, the auxiliary support mechanism also includes a roller rotatably connected to the second end; when the auxiliary support mechanism is in a supporting state, the roller abuts against the bottom of the drawer; when the auxiliary support mechanism is in a retracted state, the roller abuts against the side wall of the drawer.

[0009] As a further improvement of the present invention, the auxiliary support mechanism also includes a limiting structure fixedly connected to the bottom wall of the box body, and the limiting structure is used to limit the forward rotation angle of the support rod.

[0010] As a further improvement of the present invention, the limiting structure includes a fixing portion fixedly connected to the box body and a supporting portion protruding upward from the fixing portion; when the auxiliary supporting mechanism is in a supporting state, the upper end of the supporting portion abuts against the supporting rod.

[0011] As a further improvement of the present invention, the auxiliary support mechanism also includes two connecting parts symmetrically arranged on both sides of the fixing part along the left-right direction, and the first end is rotatably connected to the two connecting parts.

[0012] As a further improvement of the present invention, the auxiliary support mechanism also includes a slide fixed to the bottom of the drawer and extending in the front-to-back direction; when the auxiliary support mechanism switches from the retracted state to the supporting state, the roller slides from the front end of the slide to the rear end of the slide.

[0013] As a further improvement of the present invention, the auxiliary support mechanism also includes a reset member provided between the connecting portion and the first end, and the reset member is used to drive the support rod to rotate backward.

[0014] As a further improvement of the present invention, along the left-right direction, the refrigeration device includes a pair of auxiliary support mechanisms arranged at intervals.

[0015] The refrigeration device of the present invention is provided with an auxiliary supporting mechanism connected to the box body. When the drawer is pulled in the front-rear direction, the auxiliary supporting mechanism provides an upward supporting force to the drawer, thereby reducing the load borne by the slide rail assembly.

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

[0025] It should be understood that the terms used herein, such as "upper", "lower", "outer", "inner", etc., indicating spatial relative positions are used for the purpose of convenience to describe the relationship of one unit or feature relative to another unit or feature as shown in the drawings. The spatial relative position terms may be intended to include different orientations of the device in use or operation other than the orientation shown in the drawings.

[0026] See also Figures 1 to 8 As shown, the present invention provides a refrigeration device, including a box body 1 for storing articles, wherein a drawer 2 is arranged in the box body 1, and the drawer 2 is slidably connected to the box body 1 along the front-rear direction. Specifically, the refrigeration device is provided with a slide rail assembly between the box body 1 and the drawer 2, and when the user needs to take or place articles, the slide rail assembly can drive the drawer 2 to slide forward when the drawer 2 is pulled, so that the user can take or place articles with time and effort, thereby improving the user's use experience.

[0027] It is understandable that when the refrigeration device is in use, the side close to the user is the front, and the side away from the user is the back. An opening is provided on the front side of the box 1 of the refrigeration device, through which part of the drawer 2 is pulled out of the refrigeration device, so as to facilitate the user to take and put items. In addition, the refrigeration device also includes a door body for opening and closing the opening. When the door body is closed, a closed refrigeration space is formed inside the refrigeration device.

[0028] Furthermore, two sets of slide rail assemblies are symmetrically provided on the left and right sides of the drawer 2, so that when the drawer 2 is pulled out, the forces on both sides of the drawer 2 are balanced.

[0029] In the present invention, the refrigeration device further comprises an auxiliary support mechanism 3 connected to the box body 1. When the drawer 2 is pulled in the front-rear direction, the auxiliary support mechanism 3 provides an upward support force to the drawer 2, thereby reducing the load borne by the slide rail assembly. Without replacing the slide rail assembly, the user's demand for large-volume refrigeration equipment is met, which not only reduces the manufacturing cost of large-volume refrigeration equipment, but also avoids deformation of the slide rail during use and the problem of affecting the quality of the refrigeration equipment. .

[0030] Further, see Figures 2 to 6 As shown, when the drawer 2 is pulled out to the preset position, the auxiliary support mechanism 3 is in a supporting state; when the drawer 2 is fully retracted into the box body 1, the auxiliary support mechanism 3 is in a retracted state, see Figure 7 , Figure 8 As shown, after the user pushes back the drawer 2, the auxiliary support mechanism 3 will not affect the closing of the door body.

[0031] Furthermore, the auxiliary support mechanism 3 includes a support rod 31, and the support rod 31 includes a first end 311 rotatably connected to the bottom wall of the box body 1 and a second end 312 for supporting the drawer 2. When the supporting device is in a supporting state, the second end 312 of the support rod 31 provides an upward supporting force for the drawer 2, thereby reducing the load on the slide rail assembly through the supporting force provided by the support rod 31, thereby meeting the user's demand for large-volume refrigeration equipment without replacing the slide rail assembly, thereby reducing the manufacturing cost of the large-volume refrigeration equipment and avoiding deformation of the slide rail during use and problems affecting the quality of the refrigeration equipment.

[0032] In a specific embodiment of the present invention, the auxiliary support mechanism 3 further includes a roller 32 rotatably connected to the second end 312; when the auxiliary support mechanism 3 is in a supporting state, the roller 32 abuts against the bottom of the drawer 2, and the roller 32 provides an upward supporting force to the drawer 2. When the auxiliary support mechanism 3 is in a retracted state, the roller 32 abuts against the side wall of the drawer 2, so that after the drawer 2 is fully retracted into the cabinet 1, the auxiliary support mechanism 3 will not interfere with the closing of the door of the refrigeration device.

[0033] It can be understood that in the initial state, the drawer 2 is completely located in the box body 1, the auxiliary support mechanism 3 is in a retracted state, and the roller 32 is in abutment against the side wall of the drawer 2 facing the opening. When the user pulls out the drawer 2, the drawer 2 slides forward relative to the box body 1. At the same time, the drawer 2 applies a forward thrust to the roller 32 and the support rod 31, so that the support rod 31 uses the first end 311 as the rotation axis, and the support rod 31 drives the roller 32 to rotate forward. When the roller 32 is in abutment against the bottom of the drawer 2, the auxiliary support mechanism 3 is in a supporting state, and the roller 32 provides an upward supporting force to the drawer 2, thereby reducing the load borne by the slide rail assembly. Without replacing the slide rail assembly, the user's demand for large-volume refrigeration equipment is met, which not only reduces the manufacturing cost of large-volume refrigeration equipment, but also avoids deformation of the slide rail during use and the occurrence of problems affecting the quality of the refrigeration equipment. When the user pushes back the drawer 2, the drawer 2 slides backward relative to the box body 1 until the thrust applied by the drawer 2 to the roller 32 and the support rod 31 disappears, and the support rod 31 drives the roller 32 to rotate backward until the roller 32 abuts against the side wall of the drawer 2, switching the auxiliary support mechanism 3 to the retracted state.

[0034] Furthermore, the auxiliary support mechanism 3 also includes a limiting structure 33 fixedly connected to the bottom wall of the box body 1, see Figure 4 As shown, the limiting structure 33 is used to limit the forward rotation angle of the support rod 31, so that the support rod 31 and the bottom wall of the box body 1 are maintained at a predetermined angle, and the supporting rod 31 is provided with an upward supporting force through the limiting structure 33, and the supporting rod 31 transmits the upward supporting force to the drawer 2 through the roller 32.

[0035] Specifically, the limiting structure 33 includes a fixing portion 331 fixedly connected to the box body 1 and a supporting portion 332 protruding upward from the fixing portion 331; when the auxiliary supporting mechanism 3 is in a supporting state, the upper end of the supporting portion 332 abuts against the supporting rod 31, and the supporting portion provides an upward supporting force to the supporting rod 31, and the supporting rod 31 transmits the upward supporting force to the drawer 2 through the roller 32, thereby reducing the load borne by the slide rail assembly. Without replacing the slide rail assembly, the user's demand for large-volume refrigeration equipment is met, which not only reduces the manufacturing cost of large-volume refrigeration equipment, but also avoids deformation of the slide rail during use and the occurrence of problems affecting the quality of the refrigeration equipment.

[0036] Furthermore, the auxiliary support mechanism 3 also includes two connecting parts 333 symmetrically arranged on both sides of the fixing part 331 along the left-right direction, and the first end 311 is rotatably connected to the two connecting parts 333. Specifically, an axis hole can be arranged on each connecting part 333 and the first end 311, and the rotating shaft is sequentially inserted into the axis hole of one connecting part 333, the axis hole of the first end 311, and the axis hole of the other connecting part 333, and the rotating shaft is axially limited at the two connecting parts 333, so that the first end 311 can rotate around the rotating shaft, so that the support rod 31 can rotate forward and backward, so that the roller 32 can abut against the bottom wall of the drawer 2 or against the side wall of the drawer 2, that is, the auxiliary support mechanism 3 can be switched between the supporting state and the retracted state.

[0037] The auxiliary support mechanism 3 further includes a reset member 334 disposed between the connecting portion 333 and the first end 311, and the reset member 334 is used to drive the support rod 31 to rotate backward, that is, when the drawer 2 is pushed back, the reset member 334 drives the drawer 2 to rotate backward quickly, so that the auxiliary support mechanism 3 is quickly converted to the retracted state. Specifically, the reset member can be a torsion spring disposed on the rotating shaft. Of course, it can be understood that the structure of the reset member 334 is not limited to this.

[0038] Furthermore, the auxiliary support mechanism 3 also includes a slide 335 fixed to the bottom of the drawer 2 and extending in the front-to-back direction. The slide 335 guides the roller 32 to slide in the front-to-back direction, thereby reducing the friction between the roller 32 and the bottom of the drawer 2 during movement, thereby improving the stability and reliability of the auxiliary support mechanism 3.

[0039] Specifically, when the auxiliary support mechanism 3 switches from the retracted state to the supporting state, the roller 32 slides from the front end of the slideway 335 to the rear end of the slideway 335. When the auxiliary support mechanism 3 switches from the supporting state to the retracted state, the roller 32 slides from the front end of the slideway 335 to the rear end of the slideway 335.

[0040] Furthermore, the refrigeration device includes a pair of the auxiliary support mechanisms 3 arranged at intervals, which reduces the load borne by each auxiliary support mechanism 3, avoids deformation of the auxiliary support mechanism 3 due to excessive force, and improves the structural stability of the auxiliary support mechanism 3.

[0041] The refrigeration device of the present invention is provided with an auxiliary support mechanism 3 connected to the box body 1. When the drawer 2 is pulled in the front-to-back direction, the auxiliary support mechanism 3 provides an upward support force to the drawer 2, thereby reducing the load borne by the slide rail assembly. Without replacing the slide rail assembly, the user's demand for large-capacity refrigeration equipment is met, which not only reduces the manufacturing cost of the large-capacity refrigeration equipment, but also avoids deformation of the slide rail during use and the occurrence of problems affecting the quality of the refrigeration equipment.
