Abstract
Description
Technical Field
[0001] This application relates to the field of refrigerator technology, and in particular to a double-layer drawer for a refrigerator and a refrigerator. Background Technology
[0002] The refrigerator compartment has drawers for storing fruits and vegetables. To reduce condensation inside the drawers, the drawer opening is usually sealed to the refrigerator cabinet. Cold air inside the cabinet radiates from the back of the drawer to the front to maintain a suitable temperature inside the drawer.
[0003] However, because the cold air radiates from the back to the front of the drawer, the heat exchange between the drawer and the cold air is not uniform. The bottom and back walls of the drawer exchange heat more strongly with the cold air, so condensation is more likely to form. Furthermore, when fruits and vegetables are placed in the drawer, they come into direct contact with the condensation on the bottom and back walls of the drawer, making them prone to rotting. Utility Model Content
[0004] Therefore, it is necessary to provide a refrigerator with a double-layer drawer and a refrigerator that can solve the problem of fruits and vegetables easily rotting when in contact with condensation inside the closed drawer.
[0005] A double-layer drawer for a refrigerator is installed inside the refrigerator cabinet. The double-layer drawer includes a drawer body and an inner layer. The drawer body has a receiving cavity and an opening. The opening connects to the receiving cavity and can be sealed with the refrigerator cabinet. The inner layer is installed in the receiving cavity and spaced apart from the wall of the receiving cavity. The inner layer includes a hollowed-out bottom wall and a first side wall. The bottom wall is corresponding to the bottom surface of the receiving cavity, and the first side wall is corresponding to the rear side surface of the receiving cavity.
[0006] In one embodiment, the bottom wall is provided with a first reinforcing rib, one end of which is connected to the bottom wall and the other end of which abuts against the bottom surface of the receiving cavity; or, the bottom surface of the receiving cavity is provided with a first reinforcing rib, one end of which is connected to the bottom surface of the receiving cavity and the other end of which abuts against the bottom wall.
[0007] In one embodiment, the bottom wall has a plurality of spaced first through holes, and each first through hole is surrounded by a second reinforcing rib.
[0008] In one embodiment, the inner layer further includes two hollowed-out second sidewalls, one of which is disposed corresponding to the left side of the receiving cavity, and the other of which is disposed corresponding to the right side of the receiving cavity.
[0009] In one embodiment, the inner layer further includes a third sidewall, which is disposed corresponding to the front side of the receiving cavity; the first sidewall, the second sidewall and the third sidewall are interconnected around the bottom wall and respectively connected to the bottom wall, and the first sidewall, the second sidewall and the third sidewall form an opening on the side away from the bottom wall.
[0010] In one embodiment, the inner layer has a flange structure extending circumferentially, the flange structure extending toward and abutting against the inner peripheral wall of the receiving cavity.
[0011] In one embodiment, the distance between the bottom wall and the bottom surface of the receiving cavity is L1, the distance between the first side wall and the rear side surface of the receiving cavity is L2, and the distance between the second side wall and the left or right side surface of the receiving cavity is L3, wherein L1≥L2 and L1>L3.
[0012] In one embodiment, the inner layer is further provided with a handle structure for the user to hold.
[0013] In one embodiment, the handle structure includes an opening formed in the second sidewall and located near the opening.
[0014] A refrigerator includes a cabinet and a double-layer drawer as described in any of the above embodiments, wherein when the drawer body is installed in the cabinet, the opening can be sealed with the refrigerator cabinet.
[0015] Compared with existing technologies, the double-layer drawer and refrigerator provided in this application have an inner layer component installed inside the drawer body. This inner layer component is installed within the receiving cavity and spaced apart from the cavity wall. Therefore, when fruits and vegetables are placed in the inner layer component, a gap is formed between the fruits and vegetables and the cavity wall, preventing direct contact with condensation on the cavity wall. Furthermore, since the refrigerator's cold air radiates from the rear to the front of the drawer body, condensation is more likely to form on the bottom and rear sides of the receiving cavity. By providing a perforated bottom wall and first side wall, even if condensation forms on the bottom and first side walls, the condensation will drip from them onto the bottom of the receiving cavity, further preventing the fruits and vegetables from rotting.

[0029] The refrigerator compartment has drawers for storing fruits and vegetables. To reduce condensation inside the drawers, the drawer opening is usually sealed to the refrigerator cabinet. Cold air inside the cabinet radiates from the back of the drawer to the front to maintain a suitable temperature inside the drawer.
[0030] However, because the cold air radiates from the back to the front of the drawer, the heat exchange between the drawer and the cold air is not uniform. The bottom and back walls of the drawer exchange heat more strongly with the cold air, so condensation is more likely to form. Furthermore, when fruits and vegetables are placed in the drawer, they come into direct contact with the condensation on the bottom and back walls of the drawer, making them prone to rotting.
[0031] Please see Figures 1 to 5To address the aforementioned problems, this application provides a double-layer drawer 100 for a refrigerator. The double-layer drawer 100 is installed inside the refrigerator cabinet and includes a drawer body 10 and an inner layer component 20. The drawer body 10 has a receiving cavity 11 and an opening 12. The opening 12 connects to the receiving cavity 11 and can seal against the refrigerator cabinet. The inner layer component 20 is installed in the receiving cavity 11 and spaced apart from the wall of the receiving cavity 11. The inner layer component 20 includes a perforated bottom wall 21 and a first side wall 22. The bottom wall 21 corresponds to the bottom surface of the receiving cavity 11, and the first side wall 22 corresponds to the rear side surface of the receiving cavity 11. It is understood that by providing the inner layer component 20 inside the drawer body 10, and by installing the inner layer component 20 in the receiving cavity 11 and spaced apart from the wall of the receiving cavity 11, when fruits and vegetables are placed in the inner layer component 20, a gap is formed between the fruits and vegetables and the wall of the receiving cavity 11, thus preventing direct contact with condensation on the wall of the receiving cavity 11. Furthermore, since the cold air from the refrigerator radiates from the back to the front of the drawer body 10, condensation is more likely to form on the bottom and back sides of the receiving cavity 11. By setting the perforated bottom wall 21 and the first side wall 22, even if condensation forms on the bottom wall 21 and the first side wall 22, the condensation will drip from the bottom wall 21 and the first side wall 22 onto the bottom of the receiving cavity 11, which helps to further prevent fruits and vegetables from rotting.
[0032] In one embodiment, such as Figures 3 to 5 As shown, the bottom wall 21 is provided with a first reinforcing rib 211, one end of which is connected to the bottom wall 21, and the other end abuts against the bottom surface of the receiving cavity 11. It can be understood that, since the bottom wall 21 bears the weight of the fruits and vegetables, by providing the first reinforcing rib 211, the first reinforcing rib 211 forms a support between the bottom wall 21 and the drawer body 10, thereby improving the load-bearing capacity of the inner layer 20 and maintaining a gap between the bottom wall 21 and the drawer body 10.
[0033] Alternatively, in another embodiment, a first reinforcing rib 211 may be provided on the bottom surface of the receiving cavity 11, with one end of the first reinforcing rib 211 connected to the bottom surface of the receiving cavity 11 and the other end abutting against the bottom wall 21.
[0034] Alternatively, in another embodiment, the bottom wall of the drawer body 10 is formed with a wavy rib 13, and when the drawer body 10 is placed in the receiving cavity 11, the bottom wall 21 is pressed against the rib 13.
[0035] Alternatively, in one embodiment, as Figure 6As shown, the bottom wall 21 has a plurality of spaced-apart first through holes 212, and each first through hole 212 is surrounded by a second reinforcing rib 213. It is understood that the area around the first through holes 212 is a weak point of the bottom wall 21, and by providing a second reinforcing rib 213 around each first through hole 212, the structural strength of the bottom wall 21 is improved. Exemplarily, the second reinforcing rib 213 is arranged in a rectangular frame around the first through hole 212.
[0036] In one embodiment, such as Figure 5 As shown, the inner layer 20 also includes two perforated second sidewalls 24, one of which is disposed corresponding to the left side of the receiving cavity 11, and the other of which is disposed corresponding to the right side of the receiving cavity 11. By providing two second sidewalls 24, it is possible to prevent fruits and vegetables from coming into contact with condensation on the right or left side of the receiving cavity 11, and to facilitate the dripping of condensation on the inner layer 20 onto the bottom surface of the receiving cavity 11.
[0037] In one embodiment, the inner layer 20 further includes a third sidewall 25, which is correspondingly disposed on the front side of the receiving cavity 11. The first sidewall 22, the second sidewall 24, and the third sidewall 25 are interconnected around the bottom wall 21 and respectively connected to the bottom wall 21. The first sidewall 22, the second sidewall 24, and the third sidewall 25 form an opening 28 on the side away from the bottom wall 21. That is, in this embodiment, the inner layer 20 is configured as a pentahedral structure with an opening 28, and the opening 28 of the inner layer 20 corresponds to the opening 12 of the drawer body 10. This facilitates the user placing fruits and vegetables into the inner layer 20 through the opening 28.
[0038] The third side wall 25 can be configured as either open or closed. The first side wall 22, second side wall 24, third side wall 25, and bottom wall 21 are configured as a single injection-molded structure. The inner layer 20 can be placed inside the drawer body 10 through the opening 12, facilitating its insertion and removal from the drawer body 10. In actual use of the refrigerator double-layer drawer 100, the inner layer 20 and drawer body 10 form a drainage structure, allowing for the washing of fruits and vegetables along the edges of the refrigerator double-layer drawer 100 before placing the entire refrigerator double-layer drawer 100 into the refrigerator cabinet.
[0039] Furthermore, in one embodiment, a plurality of spaced-apart second through holes 221 are formed on the first sidewall 22, and a plurality of spaced-apart third through holes 241 are formed on the second sidewall 24. The first through holes 212, second through holes 221, and third through holes 241 are of the same size, and the first through holes 212 are most sparsely distributed on the bottom wall 21. This is beneficial for improving the load-bearing capacity of the inner layer component 20.
[0040] In one embodiment, such as Figure 5 As shown, the inner layer 20 has a flange structure 27 extending circumferentially. The flange structure 27 extends toward and abuts against the inner peripheral wall of the receiving cavity 11. It can be understood that when the inner layer 20 is placed in the drawer body 10, the flange structure 27 provides support between the inner layer 20 and the drawer body 10, thereby maintaining a distance between the inner layer 20 and the inner peripheral wall of the receiving cavity 11 while preventing the inner layer 20 from shaking inside the drawer body 10. Furthermore, the distance between the inner layer 20 and the inner peripheral wall of the receiving cavity 11 can be adjusted by setting the width of the flange structure 27.
[0041] Alternatively, in one embodiment, as Figure 3 and Figure 4 As shown, the distance between the bottom wall 21 and the bottom surface of the receiving cavity 11 is L1, the distance between the first side wall 22 and the rear side surface of the receiving cavity 11 is L2, and the distance between the second side wall 24 and the left or right side surface of the receiving cavity 11 is L3, where L1 ≥ L2 and L1 > L3. That is, the distance between the first side wall 22 of the inner layer 20 and the rear side surface of the receiving cavity 11 is the largest. It is understandable that since the refrigerator's cold air radiates from the rear to the front of the drawer body 10, condensation is most likely to occur on the rear side surface of the receiving cavity 11. By setting the distance between the first side wall 22 of the inner layer 20 and the rear side surface of the receiving cavity 11 to be the largest, it can adapt to the airflow direction of the refrigerator and the condensation situation on different walls of the drawer body 10.
[0042] The distance between the first sidewall 22 and the rear side of the receiving cavity 11, the distance between the second sidewall 24 and the left / right side of the receiving cavity 11, and the distance between the third sidewall 25 and the front side of the receiving cavity 11 can be set differently according to actual needs.
[0043] In one embodiment, such as Figure 5 As shown, the inner layer 20 is also provided with a handle structure 26 for the user to hold. This makes it convenient for the user to pick up and put down the inner layer 20.
[0044] Optionally, the handle structure 26 includes an opening 261, which is formed on the second sidewall 24 and located near the opening 12. This makes the handle structure 26 simple and easy to manufacture. Each second sidewall 24 has one opening 261, and the two openings 261 are symmetrically arranged on the inner layer 20. However, this is not a limitation; the handle structure 26 can also be configured as a plastic strip, with both ends connected to the inner layer 20, and the middle of the plastic strip suspended.
[0045] This application also provides a refrigerator, which includes a double-layer drawer 100 as described in any of the embodiments above. When the drawer body 10 is installed in the cabinet, the opening 12 can seal with the refrigerator cabinet. This prevents cold air from entering the drawer body 10, thereby reducing condensation inside the drawer body 10. Specifically, the sealing performance of the drawer body 10 can be improved by providing a sealing strip at the interface between the opening 12 and the cabinet.
[0046] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0047] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
