Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of household appliances, and in particular to a refrigerator. Background Art

[0002] A refrigerator is a refrigeration device used to keep food or other items at a constant low temperature. The refrigerator body is constructed with at least one refrigeration chamber with an access opening. In order to enhance the refrigeration effect of food or other items, a push-pull sealed drawer is usually provided in the refrigeration chamber, which can seal and store the food or other items inside.

[0003] In the related art, the inner side wall of the refrigeration chamber is generally provided with a vertical guide groove. The sealed drawer generally includes a drawer body, a cover body covered on the drawer body, and a seal located between the cover body and the drawer body. The drawer body can be pushed and pulled relative to the refrigeration chamber via the access opening. The cover body is provided with a support portion slidably arranged in the guide groove. One of the drawer body and the cover body is provided with a push roller, and the other is provided with a rolling surface extending along the push-pull direction of the sealed drawer, and the rolling surface has a rolling recess. When the drawer body is located in the refrigeration chamber, the push roller is located in the rolling recess, the cover body is located directly above the drawer body, and the seal is squeezed by the cover body and the drawer body to seal the drawer body and the cover body. When the drawer body is pulled, the push roller rolls out of the rolling recess, the push roller pushes the cover body upward while rolling, and the support portion slides upward along the guide groove, so that the cover body is away from the drawer body, and the seal is separated from the cover body or the drawer body to release the seal between the drawer body and the cover body.

[0004] However, in the process of pulling the drawer body, the cover will fall downward, reducing the stability of the cover, and when the cover falls, it will collide with the inner wall of the refrigeration chamber to generate noise, and in severe cases, the inner wall of the refrigeration chamber will be damaged. Summary of the invention

[0005] The embodiment of the present application provides a refrigerator, which can solve the technical problem that when a drawer body is pulled out from a refrigeration chamber, a cover body will fall downward, reducing the stability of the cover body, and when the cover body falls, it will collide with the inner wall of the refrigeration chamber to generate noise, and in severe cases, the inner wall of the refrigeration chamber will be damaged.

[0006] In a first aspect, an embodiment of the present application provides a refrigerator, comprising a box body, a drawer body, a cover body and a sealing member, wherein the box body is configured with at least one refrigeration chamber, the refrigeration chamber having a lateral access opening; the drawer body is configured to be pushed and pulled relative to the refrigeration chamber via the access opening; the cover body is located in the refrigeration chamber and is used to cover the drawer body; the sealing member is connected to the cover body or the drawer body and is located between the cover body and the drawer body; one of the drawer body and the cover body is provided with a pushing roller, and the other is provided with a rolling surface extending along the push-pull direction of the drawer body and for the pushing roller to roll, the rolling surface having a rolling recessed portion; one of the cover body and the inner side wall of the refrigeration chamber adjacent to the access opening is provided with a supporting portion, and the other is provided with a first supporting recessed portion and a second supporting recessed portion slidably provided with the supporting portion, and the first supporting recessed portion is communicated with the second supporting recessed portion;

[0007] Wherein, when the drawer body is located in the refrigeration chamber, the pushing roller is located in the rolling recessed portion, the supporting portion is located in the first supporting recessed portion, and the cover body and the drawer body squeeze the sealing member; when the drawer body is pulled out of the refrigeration chamber, the pushing roller rolls out of the rolling recessed portion, and the pushing roller pushes the cover body upward away from the drawer body while rolling on the rolling surface, and the drawer body pulls the cover body through the sealing member to move the supporting portion into the second supporting recessed portion, and the cover body or the drawer body is separated from the sealing member.

[0008] In the refrigerator of the embodiment of the present application, the cover body is connected to the inner side wall of the refrigeration chamber by a support part slidably arranged in the first support recess and the second support recess. A push roller and a rolling surface for the push roller to roll are arranged between the cover body and the drawer body, and the rolling surface has a rolling recess. When the drawer body is located in the refrigeration chamber, the push roller is located in the rolling recess, the support part is located in the first support recess, the cover body is covered on the drawer body, and the cover body and the drawer body squeeze the sealing member, thereby sealing the cover body and the drawer body. When the drawer body is pulled out of the refrigeration chamber, the push roller rolls out of the rolling recess, the push roller rolls on the rolling surface while applying an upward thrust to the cover body, and the drawer body moves out of the refrigeration chamber while applying a pulling force to the cover body through the sealing member. Under the combined action of the thrust and the pulling force, the support part moves from the first support recess to the second support recess, and the second support recess supports the cover body through the support part. When the drawer body continues to be pulled, the cover body will not fall downward due to the supporting effect of the second supporting recess, thereby improving the stability of the cover body and preventing the cover body from colliding with the inner wall of the refrigeration chamber to generate noise and preventing the inner wall of the refrigeration chamber from being damaged.

[0009] In some embodiments of the present application, the first supporting recessed portion and the second supporting recessed portion are arranged on the inner side wall of the refrigeration chamber adjacent to the access port, the second supporting recessed portion is closer to the access port than the first supporting recessed portion, and the bottom of the second supporting recessed portion is higher than the bottom of the first supporting recessed portion; the supporting portion is arranged on the side of the cover body facing the inner side wall of the refrigeration chamber; when the drawer body is located in the refrigeration chamber, the supporting portion abuts against the bottom of the first supporting recessed portion; when the drawer body is pulled out of the refrigeration chamber, the supporting portion abuts against the bottom of the second supporting recessed portion.

[0010] In this way, the first support recess and the second support recess are arranged on the inner side wall of the refrigeration chamber, and the support part is arranged on the cover. When the cover is assembled on the inner side wall of the refrigeration chamber, the support part can be aligned with the first support recess or the second support recess when the first support recess and the second support recess are observed, and the support part is inserted into the first support recess or the second support recess. In other implementations of the embodiment of the present application, the first support recess and the second support recess are arranged on the cover, and the support part is arranged on the inner side wall of the refrigeration chamber. When the cover is assembled on the inner side wall of the refrigeration chamber, the first support recess or the second support recess needs to be sleeved on the support part. Due to the obstruction of the inner side wall of the refrigeration chamber, the first support recess and the second support recess cannot be observed, which increases the difficulty of aligning the first support recess or the second support recess with the support part, thereby increasing the difficulty of assembly between the cover and the inner side wall of the refrigeration chamber. Compared with the technical solutions of other implementation methods of the embodiments of the present application, the assembly difficulty of the cover body and the inner wall of the refrigeration chamber in this technical solution is small, which improves the assembly speed of the refrigerator and thus improves the production efficiency of the refrigerator.

[0011] In some embodiments of the present application, the rolling surface also includes a flat portion, which is connected to the rolling recessed portion; when the pushing roller is located in the rolling recessed portion, there is a first distance between the rolling end point of the rolling surface of the pushing roller located in the rolling recessed portion and the plane where the flat portion is located; there is a second distance between the bottom point of the first supporting recessed portion and the bottom point of the second supporting recessed portion, and the second distance is equal to the first distance.

[0012] With such arrangement, when the drawer body is located in the refrigeration chamber, the push roller is located in the rolling recessed portion, and the rolling surface of the push roller is located in the rolling recessed portion, and the distance between the rolling end point and the plane where the flat portion is located is the first distance. When the drawer body is pulled, the push roller rolls out from the rolling recessed portion to the flat portion, and the push roller pushes the cover body to move upward by the first distance. There is a second distance between the bottom point of the first support recessed portion and the bottom point of the second support recessed portion. Since the second distance is equal to the first distance, when the drawer body pulls the cover body through the sealing member, the cover body can roll from the first support recessed portion to the second support recessed portion under the force applied to it by the push roller and the drawer body. And when the support portion rolls into the second support recessed portion, the push roller can still contact with the flat portion, thereby reducing the friction between the drawer body and the cover body, facilitating the pulling of the drawer body, and improving the stability of the movement of the drawer body.

[0013] In some embodiments of the present application, a connecting portion is provided between the first supporting recess and the second supporting recess, a third distance is provided between the vertex of the connecting portion and the bottom point of the first supporting recess, and the third distance is greater than the first distance.

[0014] With such a configuration, when the drawer body is pulled, the push roller applies an upward thrust to the cover body, and the drawer body applies a pulling force to the cover body through the sealing member. Under the action of the thrust, pulling force and inertia, the cover body can pass over the connecting portion and enter the second supporting recessed portion. The connecting portion can block the supporting portion located in the second supporting recessed portion, preventing the supporting portion from falling back into the first supporting recessed portion, thereby improving the position stability of the cover body.

[0015] In some embodiments of the present application, the difference between the third distance and the first distance is greater than or equal to 0.3 mm and less than or equal to 0.7 mm.

[0016] In this way, when the height difference between the third distance and the first distance is within the numerical range, it can be ensured that the support portion passes over the connecting portion and enters the second support recess, and the connecting portion can block the support portion. If the height difference between the third distance and the first distance is lower than the numerical range, the height of the connecting portion is too small and the support portion cannot be effectively blocked. If the height difference between the third distance and the first distance is higher than the numerical range, the height of the connecting portion is too large and the support portion cannot pass over the connecting portion and enter the second support recess, so that the second support recess cannot provide a support function for the support portion, and the cover will still fall downwards during the process of pulling the drawer body.

[0017] In some embodiments of the present application, the support portion is sleeved with a shock-absorbing ring, and the shock-absorbing ring abuts against the first supporting recessed portion or the second supporting recessed portion.

[0018] In this arrangement, when the support part slides from the first support recess to the second support recess, or returns from the second support recess to the first support recess, the shock-absorbing ring can reduce the vibration between the support part and the first support recess and the second support recess, thereby reducing the vibration of the cover body.

[0019] In some embodiments of the present application, the number of the first supporting recesses and the second supporting recesses is two groups, and the two groups of the first supporting recesses and the second supporting recesses are arranged at intervals along the depth direction of the refrigeration chamber; the number of the supporting portions is two, one of the supporting portions is slidably disposed in one group of the first supporting recesses and the second supporting recesses, and the other of the supporting portions is slidably disposed in another group of the first supporting recesses and the second supporting recesses.

[0020] With such arrangement, the two groups of first supporting recesses and second supporting recesses and the two supporting portions can simultaneously support the cover at two positions spaced apart in the depth direction of the refrigeration chamber, thereby improving the movement stability and position stability of the cover.

[0021] In some embodiments of the present application, there are two groups of the drawer bodies and the cover bodies, and the two groups of the drawer bodies and the cover bodies are spaced apart along the width direction of the refrigeration chamber, and a partition is provided between the two groups of the drawer bodies and the cover bodies; one of the cover body and the partition on one side facing the cover body is provided with the support portion, and the other is provided with the first support recessed portion and the second support recessed portion.

[0022] In this way, when two sets of drawer bodies and cover plates are arranged in the refrigeration chamber along the width direction thereof, the two sets of drawer bodies and cover plates are separated by the partition plate. A first supporting recessed portion, a second supporting recessed portion and a supporting portion are arranged between the partition plate and the cover body, so that both ends of the cover body along the width direction of the refrigeration chamber are supported, thereby improving the moving stability and position stability of the cover body.

[0023] In some embodiments of the present application, the rolling surface includes a first rolling surface and a second rolling surface, the first rolling surface is arranged on a side of the cover body facing the drawer body, the first rolling surface has a first flat portion and a first rolling recessed portion connected to each other, and the first rolling recessed portion is close to an end of the cover body located in the refrigeration chamber; the second rolling surface is arranged on a side of the drawer body facing the cover body, the second rolling surface has a second flat portion and a second rolling recessed portion connected to each other, and the second rolling recessed portion is away from an end of the drawer body located in the refrigeration chamber; the pushing roller includes a first pushing roller, the first pushing roller is connected to the drawer body and is close to an end of the drawer body located in the refrigeration chamber, and the rolling surface of the first pushing roller protrudes from the second flat portion; the second pushing roller is connected to the cover body and is away from an end of the cover body located in the refrigeration chamber, and the rolling surface of the second pushing roller protrudes from the first flat portion.

[0024] With such a configuration, when the drawer body is located in the refrigeration chamber, the first push roller is located in the first rolling recessed portion, and the second push roller is located in the second rolling recessed portion. When the drawer body is pulled, the first push roller rolls out of the first rolling recessed portion to the first flat portion and rolls on the first flat portion. The second push roller rolls out of the second rolling recessed portion to the second flat portion and rolls on the second flat portion. The first push roller and the second push roller apply thrust to the cover body at two locations in the depth direction y of the refrigeration chamber, thereby improving the uniformity of force on the cover body, allowing the entire cover body to move upward, avoiding the deflection of the cover body due to uneven force, and improving the stability of movement of the cover body. In addition, the drawer body and the cover body are in contact through the first push roller rolling on the first rolling surface and the second push roller rolling on the second rolling surface, thereby improving the stability of relative movement of the drawer body and the cover body.

[0025] In a second aspect, an embodiment of the present application provides a refrigerator, comprising:

[0026] A box body, which is configured with at least one refrigeration chamber, wherein the refrigeration chamber has a lateral access opening;

[0027] A drawer body, which is configured to be pushable and pullable relative to the refrigeration chamber via the access opening;

[0028] A cover body, which is located in the refrigeration chamber and is configured to have a first support position and a second support position between the inner side wall of the refrigeration chamber and the access opening, wherein the second support position is closer to the access opening than the first support position, and the second support position is higher than the first support position; one of the cover body and the drawer body is provided with a pushing roller, and the other is provided with a rolling surface extending along the push-pull direction of the drawer body and for the pushing roller to roll, wherein the rolling surface has a rolling recess;

[0029] A sealing member connected to the cover or the drawer body and located between the cover and the drawer body;

[0030] Wherein, when the drawer body is located in the refrigeration chamber, the pushing roller is located in the rolling recessed portion, the cover body is supported at a first supporting position, and the cover body and the drawer body squeeze the sealing member; when the drawer body is pulled out of the refrigeration chamber, the pushing roller rolls out of the rolling recessed portion, and the pushing roller pushes the cover body upward away from the drawer body, and the drawer body pulls the cover body through the sealing member, so that the cover body is supported at a second supporting position, and the cover body or the drawer body is separated from the sealing member.

[0031] In the refrigerator of the embodiment of the present application, when the drawer body is located in the refrigeration chamber, the cover body is fixed at a first supporting position relative to the inner side wall of the refrigeration chamber. When the drawer body is pulled, the push roller rolls out of the rolling recess, and the push roller rolls on the rolling surface while applying an upward thrust to the cover body. The drawer body moves out of the refrigeration chamber while applying a pulling force toward the access port to the cover body through the sealing member. Under the combined action of the thrust and the pulling force, the cover body moves obliquely upward relative to the inner side wall of the refrigeration chamber, so that the cover body is supported at a second supporting position higher than the first supporting position and close to the access port. When the drawer body continues to be pulled, since the cover body is supported at the second supporting position, the cover body will not fall downward, thereby improving the stability of the cover body, preventing the cover body from colliding with the inner wall of the refrigeration chamber to generate noise, and preventing the inner wall of the refrigeration chamber from being damaged.

[0069] As described in the background technology, there is a technical problem in the related art that the cover will fall down during the process of pulling the drawer body out of the refrigeration chamber. The inventor has found that the reason is that in the process of pulling the drawer body, the roller pushes the cover, and the support part slides upward along the vertical guide groove, so that the cover moves away from the drawer body, and the seal is separated from the cover or the drawer body. The drawer body continues to be pulled, and the drawer body moves further out of the refrigeration chamber, so that the end of the cover located in the refrigeration chamber lacks support, and the support part slides downward along the guide groove, causing the cover to fall down, thereby reducing the stability of the cover, and when the cover falls, it will collide with the inner wall of the refrigeration chamber and generate noise, which may cause damage to the inner wall of the refrigeration chamber in severe cases.

[0070] In view of this, the refrigerator of the embodiment of the present application forms a first support position and a second support position between the cover body and the side wall of the refrigeration chamber adjacent to the access port, the second support position is closer to the access port than the first support position, and the second support position is higher than the first support position. When the drawer body is located in the refrigeration chamber, the cover body is supported at the first support position relative to the inner side wall of the refrigeration chamber. When the drawer body is pulled, the push roller rolls out of the rolling recessed portion, and the push roller applies an upward thrust to the cover body while rolling on the rolling surface. The drawer body moves out of the refrigeration chamber while applying a pulling force toward the access port to the cover body through the sealing member. Under the combined action of the thrust and the pulling force, the cover body moves obliquely upward relative to the inner side wall of the refrigeration chamber, so that the cover body is supported at the second support position higher than the first support position and close to the access port. When the drawer body continues to be pulled, since the cover body is supported at the second supporting position, the cover body will not fall downward, thereby improving the stability of the cover body, preventing the cover body from colliding with the inner wall of the refrigeration chamber to generate noise, and preventing the inner wall of the refrigeration chamber from being damaged.

[0077] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0078] refer to Figure 1 , Figure 2 and Figure 3The refrigerator of the embodiment of the present application includes a box body 100, a drawer body 200 and a cover body 300. The box body 100 is configured with at least one refrigeration chamber 110, and the refrigeration chamber 110 has a lateral access opening. The drawer body 200 is configured to be pushed and pulled relative to the refrigeration chamber 110 via the access opening. The drawer body 200 can be used to accommodate food such as fruits and vegetables or other items. The drawer body 200 is pushed into the refrigeration chamber 110 to refrigerate the food or other items in the drawer body 200. The drawer body 200 is pulled out from the refrigeration chamber 110 to facilitate the access of food or other items from the drawer body 200. The cover 300 is located in the refrigeration chamber 110. When the drawer body 200 is pushed into the refrigeration chamber 110, the cover 300 can be covered on the drawer body 200, so that the food or other items in the drawer body 200 are isolated from other food or items in the refrigeration chamber 110, reducing the air circulation between the drawer body 200 and the refrigeration chamber 110, preventing odor contamination, and improving the refrigeration effect of the food or other items in the drawer body 200. When the drawer body 200 is pulled out of the refrigeration chamber 110, the cover 300 is separated from the drawer body 200, so that food or other items can be taken out of the drawer body 200.

[0079] The refrigerator of the embodiment of the present application may further include a sealing member 400, which is connected to the cover 300 or the drawer body 200 and is located between the cover 300 and the drawer body 200. When the cover 300 is covered on the drawer body 200, the sealing member 400 is squeezed by the cover 300 and the drawer body 200, thereby sealing the cover 300 and the drawer body 200, further reducing the air circulation between the drawer body 200 and the refrigeration chamber 110, preventing odor contamination, and further improving the refrigeration effect of food or other items in the drawer body 200. When the cover 300 is separated from the drawer body 200, the sealing member 400 leaves the cover 300 or the drawer body 200, and the seal between the cover 300 and the drawer body 200 is released.

[0080] refer to Figures 1 to 3 The box body 100 may include an outer shell 120, and an inner liner 130 connected to the outer shell 120. The inner liner 130 may form a refrigeration chamber 110. A refrigeration system for forming cold air in the refrigerator may be arranged between the outer shell 120 and the inner liner 130, and the refrigeration system is communicated with the inner liner 130 to pass cold air into the refrigeration chamber 110 formed by the inner liner 130. Exemplarily, the refrigeration chamber 110 may be a freezer or a refrigerator. A foaming layer (not shown in the drawings) may be filled between the outer shell 120 and the inner liner 130, and the foaming layer can keep the refrigeration chamber 110 warm, thereby ensuring the refrigeration effect in the refrigeration chamber 110.

[0081] For example, the outer shell 120 may be a rectangular parallelepiped structure to enclose a rectangular parallelepiped space. The inner liner 130 may also be a rectangular parallelepiped structure, forming a rectangular parallelepiped refrigeration chamber 110 with a take-out opening, and the inner liner 130 is connected to the outer shell 120. The number of the inner liner 130 may be one or more. When the number of the inner liner 130 is more than one, refer to Figure 1 , the plurality of inner tanks 130 may be arranged along the height direction of the outer shell 120 , for example Figure 1 The plurality of inner containers 130 may also be arranged along the width direction of the outer shell 120, for example Figure 1 It is understandable that the plurality of inner containers 130 may also be arranged in an array in the outer shell 120, which will not be described in detail in the embodiment of the present application.

[0082] It should be noted that the width direction of the housing 120 and the width direction of the refrigeration chamber 110 are both as follows: Figure 1 The direction x shown in FIG. 1 is the depth direction of the housing 120 and the width direction of the refrigeration chamber 110. Figure 1 The direction y shown, the height direction of the housing 120 and the height direction of the refrigeration chamber 110 are both Figure 1 To facilitate the description of the technical solution of the embodiment of the present application in conjunction with the accompanying drawings, the width direction of the shell 120 and the width direction of the refrigeration chamber 110 are described as the width direction x of the shell 120 and the width direction x of the refrigeration chamber 110, respectively, the depth direction of the shell 120 and the depth direction of the refrigeration chamber 110 are described as the depth direction y of the shell 120 and the width direction y of the refrigeration chamber 110, respectively, and the height direction of the shell 120 and the height direction of the refrigeration chamber 110 are described as the height direction z of the shell 120 and the height direction z of the refrigeration chamber 110, respectively.

[0083] The drawer body 200 is configured to be pushable and pullable relative to the refrigeration chamber 110 via the access opening. Exemplarily, one of the drawer body 200 and the inner side wall 111 of the refrigeration chamber 110 adjacent to the access opening may be provided with a linear guide rail, and the other may be provided with a slider, and the slider is slidably provided on the linear guide rail. The drawer body 200 and the inner side wall 111 of the refrigeration chamber 110 are slidably connected by the linear guide rail and the slider, so that the drawer body 200 can be pushed and pulled relative to the refrigeration chamber 110.

[0084] Exemplarily, one of the drawer body 200 and the inner side wall 111 of the refrigerating chamber 110 adjacent to the access opening may be provided with a guide recess 131 extending along the depth direction y of the refrigerating chamber 110, and the other may be provided with a guide protrusion 210, which is slidably disposed in the guide recess 131. The drawer body 200 and the inner side wall 111 of the refrigerating chamber 110 are slidably connected through the guide recess 131 and the guide protrusion 210, so that the drawer body 200 can be pushed and pulled relative to the refrigerating chamber 110. Compared with the drawer body 200 and the inner side wall 111 of the refrigerating chamber 110 being slidably connected through the linear guide rail and the slider, the distance between the drawer body 200 and the inner side wall 111 of the refrigerating chamber 110 can be reduced through the sliding connection of the guide recess 131 and the guide protrusion 210, thereby improving the space utilization rate in the refrigerating chamber 110 and increasing the storage space of the refrigerator.

[0085] In some possible implementations of the present application, reference is made to Figure 4 , Figure 8 , Fig. 9 and Fig.10 The guide recess 131 may be disposed on the inner side wall 111 of the refrigeration chamber 110, and the guide protrusion 210 may be disposed on the drawer body 200. The guide recess 131 may have an entrance 132 toward the access opening, and the guide protrusion 210 may be slidably disposed in the guide recess 131 through the entrance 132, thereby improving the convenience of assembling the drawer body 200 on the inner side wall 111 of the refrigeration chamber 110.

[0086] Exemplarily, the inner side wall 111 of the refrigeration chamber 110 may also be provided with a first guide roller 133, the first guide roller 133 is close to the inlet 132, and the rolling surface of the first guide roller 133 abuts against the guide protrusion 210. When the guide protrusion 210 slides in the guide recess 131, the first guide roller 133 abuts against the guide protrusion 210, the first guide roller 133 provides auxiliary support for the guide protrusion 210, and has a small friction force with the guide protrusion 210, which improves the convenience and stability of the guide protrusion 210 when sliding, thereby improving the movement stability of the drawer body 200.

[0087] A second guide roller 220 may also be provided on one side of the drawer body 200 facing the inner side wall 111 of the refrigeration chamber 110. The second guide roller 220 is located on the side of the guide protrusion 210 facing the inside of the refrigeration chamber 110. The second guide roller 220 is located in the guide recess 131, and the rolling surface of the second guide roller 220 abuts against the guide recess 131. When the guide protrusion 210 slides in the guide recess 131, the second guide roller 220 can roll in the guide recess 131 to provide auxiliary support for the drawer body 200, and there is a small friction between the second guide roller 220 and the guide recess 131, thereby improving the movement stability of the drawer body 200.

[0088] In some other possible implementations of the present application, the guide protrusion 210 can be arranged on the inner wall 111 of the refrigeration chamber 110, and the guide recess 131 can be arranged on the drawer body 200, which will not be described in detail in the embodiments of the present application.

[0089] refer to Figure 8 , Fig. 9 , Fig.11 and Fig.12 The drawer body 200 may also be provided with a composite fresh-keeping module 230, which has the function of adjusting the humidity in the drawer body 200, and can extend the fresh-keeping time of fruits and vegetables in the drawer body 200. Exemplarily, the composite fresh-keeping module 230 may include a constant humidity layer. The constant humidity layer may include a dense plant fiber layer. When the humidity in the drawer body 200 is greater than the preset humidity, for example, the preset humidity may be 90%, the moisture permeability of the dense fiber layer will increase, so that the humidity in the drawer body 200 is reduced, and the humidity will be maintained at about the preset humidity, and the dense plant fiber layer is airtight, which is conducive to the preservation of food.

[0090] The composite fresh-keeping module 230 can also have the function of removing ethylene, which can further extend the fresh-keeping time of fruits and vegetables in the drawer body 200. Exemplarily, the composite fresh-keeping module 230 can also include an ethylene removal layer, and the ethylene removal layer can include a precious metal low-temperature catalyst layer. Precious metals, such as palladium, silver, zinc, etc., can be attached to a polypropylene resin substrate through multiple soaking, evaporation and other processes to form a precious metal low-temperature catalyst layer. The precious metal low-temperature catalyst layer can decompose ethylene to generate carbon dioxide and water. And the respiration of fruits and vegetables in the drawer body 200 can reduce the oxygen concentration in the drawer body 200, thereby enhancing the effect of preserving fruits and vegetables.

[0091] Exemplarily, the back plate of the drawer body 200 located in the refrigeration chamber 110 may be provided with a first through hole 231, and the composite fresh-keeping module 230 is covered on the first through hole 231. The refrigerator may further include a pressing plate 232, which may be located on the side of the back plate facing away from the inside of the drawer body 200, and the pressing plate 232 is provided with a second through hole 233, and the pressing plate 232 presses the composite fresh-keeping module 230 onto the back plate. The air in the drawer body 200 may enter the composite fresh-keeping module 230 through the first through hole 231, and flow out from the second through hole 233 of the pressing plate 232.

[0092] The cover 300 is located in the refrigeration chamber 110. When the drawer body 200 is located in the refrigeration chamber 110, the cover 300 is covered on the drawer body 200. When the drawer body 200 is pulled out of the refrigeration chamber 110, the cover 300 is separated from the drawer body 200. Exemplarily, the number of the cover 300 and the drawer body 200 can be one group. Exemplarily, the number of the drawer body 200 and the cover 300 can also be two groups, and the two groups of the drawer body 200 and the cover 300 can be spaced apart along the width direction x of the refrigeration chamber 110, and a partition 140 can be provided between the two groups of the drawer body 200 and the cover 300.

[0093] Exemplarily, one of the cover 300 and the drawer body 200 may be provided with a push roller, and the other may be provided with a rolling surface extending along the push-pull direction of the drawer body 200 and for the push roller to roll, and the rolling surface has a rolling recess. For example, the rolling surface may include a rolling recess and a flat portion connected. When the drawer body 200 is located in the refrigeration chamber 110, the push roller is located in the rolling recess, and the cover 300 and the drawer body 200 squeeze the seal 400 to seal the cover 300 and the drawer body 200. When the drawer body 200 is pulled out of the refrigeration chamber 110, the push roller rolls out of the rolling recess to the flat portion, and the push roller pushes the cover 300 upward away from the drawer body 200, and the cover 300 or the drawer body 200 is separated from the seal 400 to release the seal between the cover 300 and the drawer body 200.

[0094] For example, reference Figure 5 , Figure 6 , Fig.11 and Fig.14The rolling surface may include a first rolling surface 310 and a second rolling surface 240. The first rolling surface 310 is disposed on the side of the cover 300 facing the drawer body 200. The first rolling surface 310 has a first flat portion 311 and a first rolling recessed portion 312 connected to each other. The first rolling recessed portion 312 is close to one end of the cover 300 located in the refrigeration chamber 110. The second rolling surface 240 is disposed on the side of the drawer body 200 facing the cover 300. The second rolling surface 240 has a second flat portion 241 and a second rolling recessed portion 242 connected to each other. The second rolling recessed portion 242 is away from one end of the drawer body 200 located in the refrigeration chamber 110. The push roller includes a first push roller 250. The first push roller 250 is connected to the drawer body 200 and is close to one end of the drawer body 200 located in the refrigeration chamber 110. The rolling surface of the first push roller 250 protrudes from the second flat portion 241. The second pushing roller 320 is connected to the cover body 300 and is away from one end of the cover body 300 located in the refrigeration chamber 110 . The rolling surface of the second pushing roller 320 protrudes from the first flat portion 311 .

[0095] When the drawer body 200 is located in the refrigeration chamber 110, the first push roller 250 is located in the first rolling recess 312, and the second push roller 320 is located in the second rolling recess 242. When the drawer body 200 is pulled, the first push roller 250 rolls out from the first rolling recess 312 to the first flat portion 311, and rolls on the first flat portion 311. The second push roller 320 rolls out from the second rolling recess 242 to the second flat portion 241, and rolls on the second flat portion 241. The first push roller 250 and the second push roller 320 apply thrust to the cover 300 at two locations in the depth direction y of the refrigeration chamber 110, thereby improving the uniformity of the force on the cover 300, allowing the entire cover 300 to move upward, avoiding the cover 300 from being deflected due to uneven force, and improving the stability of movement of the cover 300. In addition, the drawer body 200 and the cover body 300 are in contact with each other through the first push roller 250 rolling on the first rolling surface 310 and the second push roller 320 rolling on the second rolling surface 240, thereby improving the stability of the drawer body 200 and the cover body 300 during relative movement.

[0096] refer to Figures 8 to 12 The drawer body 200 may also be provided with a limiting portion 243, which may be located on the side of the second flat portion 241 facing away from the interior of the drawer body 200. The limiting portion 243 may limit the first push roller 250 to prevent the first push roller 250 from sliding off the second flat portion 241.

[0097] A first support position and a second support position may be constructed between the cover 300 and the inner side wall 111 of the refrigeration chamber 110 adjacent to the access port, wherein the second support position is closer to the access port than the first support position, and the second support position is higher than the first support position. When the drawer body 200 is located in the refrigeration chamber 110, the cover 300 is supported at the first support position. When the drawer body 200 is pulled out of the refrigeration chamber 110, the cover 300 is supported at the second support position. When the drawer body 200 is located in the refrigeration chamber 110, the push roller is located in the rolling recess, and the cover 300 is supported at the first support position relative to the inner side wall 111 of the refrigeration chamber 110. When the drawer body 200 is pulled, after the push roller rolls out of the rolling recess, the push roller rolls on the rolling surface while applying an upward thrust to the cover 300. The drawer body 200 moves out of the refrigeration chamber 110 while applying a pulling force toward the access opening to the cover body 300 through the sealing member 400. Under the combined action of the thrust and the pulling force, the cover body 300 moves obliquely upward relative to the inner side wall 111 of the refrigeration chamber 110, so that the cover body 300 is supported at a second supporting position higher than the first supporting position and close to the access opening. When the drawer body 200 continues to be pulled, since the cover body 300 is supported at the second supporting position, the cover body 300 will not fall downward, thereby improving the stability of the cover body 300, preventing the cover body 300 from colliding with the inner wall of the refrigeration chamber 110 to generate noise, and preventing the inner wall of the refrigeration chamber 110 from being damaged.

[0098] Exemplarily, one of the cover 300 and the inner side wall 111 of the refrigeration chamber 110 adjacent to the access opening may be provided with a support portion 330, and the other may be provided with a first support recess 134 and a second support recess 135 slidably provided with the support portion 330, and the first support recess 134 is communicated with the second support recess 135. When the drawer body 200 is located in the refrigeration chamber 110, the push roller is located in the rolling recess, and the support portion 330 is located in the first support recess 134, so that the support portion 330 is supported at the first support position, and the cover 300 and the drawer body 200 squeeze the sealing member 400. When the drawer body 200 is pulled out from the refrigeration chamber 110, the pushing roller rolls out of the rolling recess, and the pushing roller pushes the cover body 300 upward and away from the drawer body 200 while rolling. The drawer body 200 pulls the cover body 300 through the sealing member 400, so that the supporting portion 330 moves into the second supporting recess 135, so that the supporting portion 330 is supported at the second supporting position, and the cover body 300 or the drawer body 200 is separated from the sealing member 400.

[0099] In the refrigerator of the embodiment of the present application, the cover 300 is connected to the inner side wall 111 of the refrigerating chamber 110 through a support portion 330 slidably arranged in the first support recess 134 and the second support recess 135. A push roller and a rolling surface for the push roller to roll are arranged between the cover 300 and the drawer body 200, and the rolling surface has a rolling recess. When the drawer body 200 is located in the refrigerating chamber 110, the push roller is located in the rolling recess, and the support portion 330 is located in the first support recess 134, so that the cover 300 is supported at the first support position, and the cover 300 is covered on the drawer body 200, and the cover 300 and the drawer body 200 squeeze the sealing member 400, thereby sealing the cover 300 and the drawer body 200. When the drawer body 200 is pulled out of the refrigeration chamber 110, the push roller rolls out of the rolling recess, and the push roller applies an upward thrust to the cover 300 while rolling on the rolling surface, and the drawer body 200 moves out of the refrigeration chamber 110 while applying a pulling force to the cover 300 through the sealing member 400. Under the combined action of the thrust and the pulling force, the support portion 330 moves from the first support recess 134 to the second support recess 135, and the second support recess 135 supports the cover 300 through the support portion 330, and supports the cover 300 at the second support position. When the drawer body 200 is continuously pulled, due to the supporting effect of the second support recess 135, the cover 300 will not fall downward, thereby improving the stability of the cover 300, preventing the cover 300 from colliding with the inner wall of the refrigeration chamber 110 to generate noise, and preventing the inner wall of the refrigeration chamber 110 from being damaged.

[0100] In some possible implementations of the present application, the support portion 330 is disposed on the inner side wall 111 of the refrigeration chamber 110. The first support recess 134 and the second support recess 135 can be disposed on the cover 300, the second support recess 135 is farther away from the access opening than the first support recess 134, and the top of the second support recess is lower than the top of the first support recess 134. The first support recess 134 and the second support recess 135 that are connected are sleeved on the support portion 330. When the drawer body 200 is located in the refrigeration chamber 110, the top of the first support recess 134 abuts against the support portion 330. When the drawer body 200 is pulled out of the refrigeration chamber 110, the top of the second support recess 135 abuts against the support portion 330.

[0101] When the drawer body 200 is located in the refrigeration chamber 110, the push roller is located in the rolling recess, and the support portion 330 is located in the first support recess 134 and abuts against the top of the first support recess 134 to support the cover 300 at the first support position. The cover 300 is covered on the drawer body 200, and the cover 300 and the drawer body 200 squeeze the seal 400, thereby sealing the cover 300 and the drawer body 200. When the drawer body 200 is pulled out of the refrigeration chamber 110, the push roller rolls out of the rolling recess, and the push roller applies an upward thrust to the cover 300 while rolling on the rolling surface, and the drawer body 200 applies a pulling force to the cover 300 through the seal 400 while moving out of the refrigeration chamber 110. Under the combined action of the pushing force and the pulling force, the second supporting recess 135 which is away from the taking-in and releasing port and whose top is lower than the first supporting recess 134 is sleeved on the supporting portion 330, and the top of the second supporting recess 135 abuts against the supporting portion 330 to support the cover body 300 at the second supporting position.

[0102] In some other possible implementations of the embodiments of the present application, refer to Figure 4 , Figure 5 , Fig.15 and Fig.16 The first support recess 134 and the second support recess 135 can be arranged on the inner side wall 111 of the refrigeration chamber 110 adjacent to the access port, the second support recess 135 is closer to the access port than the first support recess 134, and the bottom of the second support recess 135 is higher than the bottom of the first support recess 134. The support portion 330 is arranged on the side of the cover 300 facing the inner side wall 111 of the refrigeration chamber 110. When the drawer body 200 is located in the refrigeration chamber 110, the support portion 330 abuts against the bottom of the first support recess 134. When the drawer body 200 is pulled out of the refrigeration chamber 110, the support portion 330 abuts against the bottom of the second support recess 135.

[0103] When the drawer body 200 is located in the refrigeration chamber 110, the push roller is located in the rolling recess, the support portion 330 is located in the first support recess 134, and the bottom of the first support recess 134 abuts against the support portion 330, so as to support the cover 300 at the first support position. The cover 300 is covered on the drawer body 200, and the cover 300 and the drawer body 200 squeeze the sealing member 400, so as to seal the cover 300 and the drawer body 200. When the drawer body 200 is pulled out of the refrigeration chamber 110, the push roller rolls out of the rolling recess, and the push roller applies an upward thrust to the cover 300 while rolling on the rolling surface, and the drawer body 200 applies a pulling force to the cover 300 through the sealing member 400 while moving out of the refrigeration chamber 110. Under the combined action of pushing force and pulling force, the support portion 330 slides from the first support recess 134 to the second support recess 135 which is close to the loading and unloading port and has a bottom higher than the first support recess 134, and the bottom of the second support recess 135 abuts against the support portion 330 to support the cover body 300 at the second support position.

[0104] In this implementation, when the cover 300 is assembled on the inner side wall 111 of the refrigeration chamber 110, the support portion 330 can be aligned with the first support recess 134 or the second support recess 135 while the first support recess 134 and the second support recess 135 are viewed, and the support portion 330 is inserted into the first support recess 134 or the second support recess 135. However, in the above implementation, the first support recess 134 and the second support recess 135 are provided on the cover 300, and the support portion 330 is provided on the inner side wall 111 of the refrigeration chamber 110. When the cover 300 is assembled on the inner side wall 111 of the refrigeration chamber 110, the first support recess 134 or the second support recess 135 needs to be sleeved on the support portion 330. Due to the obstruction of the inner side wall 111 of the refrigeration chamber 110, the first support recess 134 and the second support recess 135 cannot be seen, which increases the difficulty of aligning the first support recess 134 or the second support recess 135 with the support portion 330, thereby increasing the difficulty of assembling the cover body 300 with the inner side wall 111 of the refrigeration chamber 110. Compared with the technical solution of the above-mentioned implementation, the assembly difficulty of the cover body 300 and the inner side wall 111 of the refrigeration chamber 110 in this implementation is small, which improves the assembly speed of the refrigerator, thereby improving the production efficiency of the refrigerator.

[0105] For example, reference Fig.15, when the push roller is located in the rolling recess, the rolling surface of the push roller is located in the rolling recess, and there is a first distance H1 between the rolling end point of the rolling recess and the plane where the flat portion is located. For example, there is a first distance H1 between the bottom point of the first push roller 250 and the plane where the first flat portion 311 is located. There is a second distance H2 between the top point of the second push roller 320 and the plane where the second flat portion 241 is located. There is a second distance H2 between the bottom point of the first support recess 134 and the bottom point of the second support recess 135, and the second distance H2 is equal to the first distance H1.

[0106] When the drawer body 200 is located in the refrigeration chamber 110, the push roller is located in the rolling recessed portion, and the rolling surface of the push roller is located at a distance between the rolling end point of the rolling recessed portion and the plane where the flat portion is located, which is the first distance H1. When the drawer body 200 is pulled, the push roller rolls out from the rolling recessed portion to the flat portion, and the push roller pushes the cover 300 to move upward by the first distance H1. There is a second distance H2 between the bottom point of the first support recessed portion 134 and the bottom point of the second support recessed portion 135. Since the second distance H2 is equal to the first distance H1, when the drawer body 200 pulls the cover 300 through the sealing member 400, the cover 300 can roll from the first support recessed portion 134 to the second support recessed portion 135 under the force applied to it by the push roller and the drawer body 200. When the support portion 330 rolls into the second support recess 135 , the push roller can still contact the flat portion, thereby reducing the friction between the drawer body 200 and the cover body 300 , making it easier to pull the drawer body 200 and improving the stability of movement of the drawer body 200 .

[0107] refer to Fig.15 , a connecting portion 136 may be provided between the first supporting recess 134 and the second supporting recess 135, and a third distance H3 is provided between the vertex of the connecting portion 136 and the bottom point of the first supporting recess 134, and the third distance H3 is greater than the first distance H1. When the drawer body 200 is pulled, the roller applies an upward thrust to the cover 300, and the drawer body 200 applies a pulling force to the cover 300 through the sealing member 400. Under the action of the thrust, pulling force and inertia, the cover 300 can pass over the connecting portion 136 and enter the second supporting recess 135. The connecting portion 136 can block the supporting portion 330 located in the second supporting recess 135, preventing the supporting portion 330 from falling back into the first supporting recess 134, thereby improving the position stability of the cover 300.

[0108] Exemplarily, the difference between the third distance H3 and the first distance H1 may be greater than or equal to 0.3 mm and less than or equal to 0.7 mm. For example, the difference between the third distance H3 and the first distance H1 may be 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm or 0.7 mm. The height difference between the third distance H3 and the first distance H1 is within this numerical range, which can ensure that the support portion 330 passes over the connecting portion 136 and enters the second supporting recess 135, and the connecting portion 136 can block the support portion 330. If the height difference between the third distance H3 and the first distance H1 is lower than this numerical range, the height of the connecting portion 136 is too small to effectively block the support portion 330. If the height difference between the third distance H3 and the first distance H1 is higher than this numerical range, the height of the connecting portion 136 is too large, and the supporting portion 330 cannot pass over the connecting portion 136 and enter the second supporting recess 135, so that the second supporting recess 135 cannot provide a supporting function for the supporting portion 330. During the process of pulling the drawer body 200, the cover body 300 will still fall downward.

[0109] refer to Figure 4 , Fig.15 and Fig.16 The number of the first support recessed parts 134 and the second support recessed parts 135 can be two groups, and the two groups of the first support recessed parts 134 and the second support recessed parts 135 can be arranged at intervals along the depth direction y of the refrigeration chamber 110. The number of the support parts 330 is two, one support part 330 is slidably disposed in one group of the first support recessed parts 134 and the second support recessed parts 135, and the other support part 330 is slidably disposed in the other group of the first support recessed parts 134 and the second support recessed parts 135. The two groups of the first support recessed parts 134 and the second support recessed parts 135 and the two support parts 330 can simultaneously support the cover body 300 at two positions spaced apart in the depth direction of the refrigeration chamber 110, thereby improving the movement stability and position stability of the cover body 300.

[0110] refer to Figure 7 When there are two groups of drawer bodies 200 and cover bodies 300, and the two groups of drawer bodies 200 and cover bodies 300 are spaced apart along the width direction of the refrigeration chamber 110, and a partition 140 is provided between the two groups of drawer bodies 200 and cover bodies 300, one of the cover body 300 and the partition 140 facing the side of the cover body 300 can be provided with a support portion 330, and the other can be provided with a first support recessed portion 134 and a second support recessed portion 135, so that both ends of the cover body 300 along the width direction of the refrigeration chamber 110 are supported, thereby improving the movement stability and position stability of the cover body 300.

[0111] refer to Fig.13 and Fig.14, the support portion 330 may be sleeved with a shock absorbing ring 340, and the shock absorbing ring 340 abuts against the first support recess 134 or the second support recess 135. When the support portion 330 slides from the first support recess 134 to the second support recess 135, or returns from the second support recess 135 to the first support recess 134, the shock absorbing ring 340 can reduce the vibration between the support portion 330 and the first support recess 134 and the second support recess 135, thereby reducing the vibration of the cover body 300. Exemplarily, the support portion 330 may be provided with a connecting groove, and the shock absorbing ring 340 is clamped in the connecting groove to prevent the shock absorbing ring 340 from falling off the support portion 330. Exemplarily, the material of the shock absorbing ring 340 may be rubber or shock absorbing plastic.
