[0039] The utility model will be further described below in conjunction with the accompanying drawings.

[0040] The drawer structure is a structure used by the refrigerator to store food. In order to ensure the sealing performance of the drawer structure, the drawer structure adopts a method of movably arranging the drawer in the drawer frame, and arranging a sealing strip between the drawer mask and the drawer frame; wherein the drawer frame includes a frame body and an upper cover arranged on the frame body, and the drawer includes a drawer bucket and a mask arranged on one side of the drawer bucket to form a drawer with an open top. However, such a sealing solution has the problems of many mold parts, high mold cost, complex assembly, and time-consuming and labor-intensive production.

[0041] Embodiment 1

[0042] like Figure 1 As shown, in order to solve the above technical problems, an embodiment of the utility model provides a drawer structure, including a drawer assembly 10, an upper cover 20 and a sealing member 30; the drawer assembly 10 is movably arranged in a refrigerator body 40, the drawer assembly 10 includes a storage cavity 110 with a top opening, and a first mating surface 120 is arranged on the top of the drawer assembly 10; the upper cover 20 is arranged in the refrigerator body 40, a second mating surface is arranged on the bottom of the upper cover 20, and the upper cover 20 closes the opening of the storage cavity 110; the sealing member 30 is arranged on the second mating surface, the sealing member 30 abuts against the first mating surface 120 and surrounds the storage cavity 110; wherein the first mating surface 120 is parallel to the second mating surface, a preset angle is arranged between the first mating surface 120 and the moving direction of the drawer assembly 10, and a side of the first mating surface 120 close to the refrigerator door is higher than a side of the first mating surface 120 away from the refrigerator door.

[0043] As can be seen from the above, by setting an upper cover 20 at the top of the storage cavity 110 to close the opening of the storage cavity 110, and setting a sealing member 30 around the storage cavity 110 between the upper cover 20 and the drawer assembly 10, the drawer assembly 10 is sealed, and the airflow inside and outside the drawer assembly 10 is effectively blocked, thereby enhancing the thermal insulation performance of the drawer assembly 10; by setting an inclined first mating surface 120 and a second mating surface, the drawer assembly 10 and the upper cover 20 are both in a high front and low back form, which not only reduces the sense of obstruction between the drawer assembly 10 and the sealing strip, facilitates the pulling and pulling of the drawer assembly 10, and improves the user experience, but also can remind the user whether the drawer assembly 10 has returned to its position during the pulling and pulling process. When it has returned to its position, the drawer assembly 10 can no longer move. At this time, the sealing member 30 is in contact with the first mating surface 120, thereby further ensuring the sealing effect and avoiding the problem of poor sealing caused by the drawer assembly 10 not returning to its position. In addition, compared with the existing drawer structure, the utility model only uses the upper cover 20 to cooperate with the drawer assembly 10, which not only reduces the mold parts such as the drawer frame, but also avoids the assembly process of the drawer frame and other components, thereby reducing production costs, saving manpower and material resources, and also saving space in the box body 40, thereby improving the space utilization rate of the refrigerator.

[0044] It should be noted that if Figure 1 As shown, the moving direction of the drawer assembly 10 is parallel to the X direction, and the height direction is parallel to the Z direction.

[0045] It should also be noted that the seal 30 includes but is not limited to TPE (thermoplastic elastomer) seal 30. TPE (thermoplastic elastomer) seal 30 has good elasticity, softness, wear resistance and processability, is non-toxic and odorless, meets environmental protection requirements, is suitable for the food field, and can be processed and formed by injection molding, extrusion, blow molding and other methods.

[0046] It should also be noted that the upper cover 20 and the drawer assembly 10 are both made of transparent materials, which have good visualization effects. The user can clearly see the food stored in the drawer assembly 10, which is convenient for the user to take out, thereby further optimizing the user experience.

[0047] It should also be noted that the size of the preset angle is set according to needs. When the pulling force is greater than the resistance of the drawer assembly 10 in the X direction, the drawer assembly 10 starts to move, that is, the pulling force must be greater than F1=cosa*fmg / (1+fsina), where f is the friction coefficient, a is the preset angle, m is the total mass of the drawer assembly 10 and the food in the drawer assembly 10, and g is the acceleration of gravity. From this formula, it can be seen that the friction resistance of the drawer assembly 10 in the X direction is inversely proportional to the preset angle a. The larger the preset angle, the faster the initial pull. When the preset angle a=0, F1 is the maximum value, and when the preset angle a=90°, F1=0; therefore, the larger the preset angle a, the smaller the friction resistance the drawer assembly 10 encounters at the initial moment of movement; however, the larger the preset angle a, the greater the height difference between the side of the drawer assembly 10 close to the box door and the side of the drawer assembly 10 away from the box body 40, and the smaller the storage capacity of the drawer assembly 10. Therefore, when setting the size of the preset angle, the user needs to take into account the two factors of friction resistance and storage capacity.

[0048] It should also be noted that the upper cover 20 is detachably disposed in the box body 40; for example, the upper cover 20 is detachably disposed on the refrigerating container of the box body 40 by snap-fitting.

[0049] It should also be noted that the refrigerator includes a box body 40 and a door rotatably arranged on the box body 40. The specific structure of the refrigerator is prior art and will not be described in detail in this application.

[0064] It should be noted that if Figure 1 As shown, the moving direction of the drawer assembly 10 is parallel to the X direction, and the height direction is parallel to the Z direction.

[0065] It should also be noted that the seal 30 includes but is not limited to TPE (thermoplastic elastomer) seal 30.

The user can clearly see the food stored in the drawer assembly 10, which is convenient for the user to take out, thereby further optimizing the user experience.

[0084] It should also be noted that the size of the preset angle is set according to needs. When the pulling force is greater than the resistance of the drawer assembly 10 in the X direction, the drawer assembly 10 starts to move, that is, the pulling force must be greater than F1=cosa*fmg / (1+fsina), where f is the friction coefficient, a is the preset angle, m is the total mass of the drawer assembly 10 and the food in the drawer assembly 10, and g is the acceleration of gravity. From this formula, it can be seen that the friction resistance of the drawer assembly 10 in the X direction is inversely proportional to the preset angle a. The larger the preset angle, the faster the initial pull. When the preset angle a=0, F1 is the maximum value, and when the preset angle a=90°, F1=0; therefore, the larger the preset angle a, the smaller the friction resistance the drawer assembly 10 encounters at the initial moment of movement; however, the larger the preset angle a, the greater the height difference between the side of the drawer assembly 10 close to the box door and the side of the drawer assembly 10 away from the box body 40, and the smaller the storage capacity of the drawer assembly 10. Therefore, when setting the size of the preset angle, the user needs to take into account the two factors of friction resistance and storage capacity.

[0085] It should also be noted that the upper cover 20 is detachably disposed in the box body 40; for example, the upper cover 20 is detachably disposed on the refrigerating container of the box body 40 by snap-fitting.

[0086] It should also be noted that the refrigerator includes a box body 40 and a door rotatably arranged on the box body 40. The specific structure of the refrigerator is prior art and will not be described in detail in this application.

[0087] In some embodiments, the preset angle is 3°.

[0088] By setting the preset angle to 3°, the user's requirements for the friction force and storage capacity of the drawer assembly 10 can be met at the same time, avoiding excessive friction resistance affecting the user experience and avoiding too small storage volume.

[0089] like Figure 3-Figure 5 As shown, in some embodiments, the drawer assembly 10 includes a tray 130 and a drawer 140; the tray 130 is movably disposed in the box body 40, and a receiving groove 1301 is disposed on the top of the tray 130; a portion of the drawer 140 is placed in the receiving groove 1301; wherein the storage cavity 110 is disposed in the drawer 140, and the first mating surface 120 is located on the top of the drawer 140.

[0090] Compared with the existing drawer structure that directly installs the drawer 140 on the guide rail 160, the drawer 140 needs to be removed from the guide rail 160 before it can be taken out. In the present invention, the tray 130 is provided to support the drawer 140, and the tray 130 is used to drive the drawer 140 to move in the X direction, so that the drawer 140 can be taken out more conveniently. In addition, compared with the existing drawer structure, the tray 130 is installed on the guide rail 160, and the tray 130 is smaller in size, lighter in weight, and is not easy to be blocked, so it is easier to operate and install in place when assembled with the guide rail 160.

[0091] like Figure 4 As shown, in some embodiments, the drawer 140 includes a limiting portion 1401 and a main body 1402; the limiting portion 1401 is adapted to the shape of the accommodating groove 1301; the main body 1402 is arranged at the top of the limiting portion 1401 and is connected to the limiting portion 1401; wherein, on a plane perpendicular to the height direction, the projection of the limiting portion 1401 is located within the projection of the main body 1402, so as to form a step surface between the limiting portion 1401 and the main body 1402 that abuts against the tray 130.

[0092] By setting a step surface that abuts against the tray 130, the drawer 140 is provided with a limiting support function; in addition, on the plane perpendicular to the height direction, the projection of the limiting portion 1401 is located within the projection of the main body 1402, and the main body 1402 is used to ensure the volume of the drawer 140, thereby achieving a large storage capacity and improving space utilization.

[0093] It should be noted that the limiting portion 1401 and the main body 1402 are connected by integrally forming with a mold.

[0094] It should also be noted that arc transitions are provided at the corners of the limiting portion 1401 and the main body portion 1402 , and the height of the limiting portion 1401 is equal to the height of the accommodating groove 1301 .

[0095] like Figure 3 , Figure 4 As shown, in some embodiments, a flange 150 is provided at one end of the main body 1402 away from the limiting portion 1401 , and the flange 150 surrounds the storage cavity 110 , wherein the first mating surface 120 is located at the top of the flange.

[0096] The flange 150 is provided to fit and abut against the seal 30 to achieve a sealing effect, thereby increasing the contact area between the drawer 140 and the seal 30, thereby avoiding the problem of poor sealing effect caused by too small a contact area between the drawer 140 and the seal 30 due to too small a thickness of the drawer 140, and increasing the contact area between the drawer 140 and the seal 30 without increasing the thickness of the drawer 140. In addition, the deformation amount of the flange 150 in the height direction is substantially zero, which can ensure the fit and abutment with the seal 30, thereby ensuring the sealing effect.

[0097] It should be noted that the maximum load-bearing design of the drawer assembly 10 is 25 kg, the seal 30 is a TPE seal 30, and the bite amount when the seal 30 and the flange 150 are in contact with each other is 2 mm; see Figure 6 , shows a simulation diagram of the drawer assembly 10. When the drawer assembly 10 carries a weight of 25 kg, the deformation of the flange 150 in the height direction is substantially zero, that is, when the drawer assembly 10 bears the maximum load, the seal 30 can still fit and abut against the flange 150 to achieve a sealing effect.

[0098] Embodiment 5

[0099] like Figure 1 As shown, the drawer structure includes a drawer assembly 10, an upper cover 20 and a sealing member 30; the drawer assembly 10 is movably arranged in the refrigerator body 40, the drawer assembly 10 includes a storage cavity 110 with a top opening, and a first mating surface 120 is arranged on the top of the drawer assembly 10; the upper cover 20 is arranged in the refrigerator body 40, a second mating surface is arranged on the bottom of the upper cover 20, and the upper cover 20 closes the opening of the storage cavity 110; the sealing member 30 is arranged on the second mating surface, the sealing member 30 abuts against the first mating surface 120 and surrounds the storage cavity 110; wherein, the first mating surface 120 is parallel to the second mating surface, a preset angle is arranged between the first mating surface 120 and the moving direction of the drawer assembly 10, and a side of the first mating surface 120 close to the refrigerator door is higher than a side of the first mating surface 120 away from the refrigerator door.

[0100] As can be seen from the above, by setting an upper cover 20 at the top of the storage cavity 110 to close the opening of the storage cavity 110, and setting a sealing member 30 around the storage cavity 110 between the upper cover 20 and the drawer assembly 10, the drawer assembly 10 is sealed, and the airflow inside and outside the drawer assembly 10 is effectively blocked, thereby enhancing the thermal insulation performance of the drawer assembly 10; by setting an inclined first mating surface 120 and a second mating surface, the drawer assembly 10 and the upper cover 20 are both in a high front and low back form, which not only reduces the sense of obstruction between the drawer assembly 10 and the sealing strip, facilitates the pulling and pulling of the drawer assembly 10, and improves the user experience, but also can remind the user whether the drawer assembly 10 has returned to its position during the pulling and pulling process. When it has returned to its position, the drawer assembly 10 can no longer move. At this time, the sealing member 30 is in contact with the first mating surface 120, thereby further ensuring the sealing effect and avoiding the problem of poor sealing caused by the drawer assembly 10 not returning to its position. In addition, compared with the existing drawer structure, the utility model only uses the upper cover 20 to cooperate with the drawer assembly 10, which not only reduces the mold parts such as the drawer frame, but also avoids the assembly process of the drawer frame and other components, thereby reducing production costs, saving manpower and material resources, and also saving space in the box body 40, thereby improving the space utilization rate of the refrigerator.

[0101] It should be noted that if Figure 1 As shown, the moving direction of the drawer assembly 10 is parallel to the X direction, and the height direction is parallel to the Z direction.

[0102] It should also be noted that the seal 30 includes but is not limited to TPE (thermoplastic elastomer) seal 30. TPE (thermoplastic elastomer) seal 30 has good elasticity, softness, wear resistance and processability, is non-toxic and odorless, meets environmental protection requirements, is suitable for the food field, and can be processed and formed by injection molding, extrusion, blow molding and other methods.

[0103] It should also be noted that the upper cover 20 and the drawer assembly 10 are both made of transparent materials, which have good visualization effects. The user can clearly see the food stored in the drawer assembly 10, which is convenient for the user to take out, thereby further optimizing the user experience.

[0104] It should also be noted that the size of the preset angle is set according to needs. When the pulling force is greater than the resistance of the drawer assembly 10 in the X direction, the drawer assembly 10 starts to move, that is, the pulling force must be greater than F1=cosa*fmg / (1+fsina), where f is the friction coefficient, a is the preset angle, m is the total mass of the drawer assembly 10 and the food in the drawer assembly 10, and g is the acceleration of gravity. From this formula, it can be seen that the friction resistance of the drawer assembly 10 in the X direction is inversely proportional to the preset angle a. The larger the inclination angle, the faster the initial movement. When the preset angle a=0, F1 is the maximum value, and when the preset angle a=90°, F1=0; therefore, the larger the preset angle a, the smaller the friction resistance the drawer assembly 10 encounters at the initial moment of movement; however, the larger the preset angle a, the greater the height difference between the side of the drawer assembly 10 close to the box door and the side of the drawer assembly 10 away from the box body 40, and the smaller the storage capacity of the drawer assembly 10. Therefore, when setting the size of the preset angle, the user needs to take into account the two factors of friction resistance and storage capacity.

[0105] It should also be noted that the upper cover 20 is detachably disposed in the box body 40; for example, the upper cover 20 is detachably disposed on the refrigerating container of the box body 40 by snap-fitting.

[0106] It should also be noted that the refrigerator includes a box body 40 and a door rotatably arranged on the box body 40. The specific structure of the refrigerator is prior art and will not be described in detail in this application.

[0107] In some embodiments, the preset angle is 3°.

[0108] By setting the preset angle to 3°, the user's requirements for the friction force and storage capacity of the drawer assembly 10 can be met at the same time, avoiding excessive friction resistance affecting the user experience and avoiding too small storage volume.

[0110] Compared with the existing drawer structure that directly installs the drawer 140 on the guide rail 160, the drawer 140 needs to be removed from the guide rail 160 before it can be taken out. In the present invention, the tray 130 is provided to support the drawer 140, and the tray 130 is used to drive the drawer 140 to move in the X direction, so that the drawer 140 can be taken out more conveniently. In addition, compared with the existing drawer structure, the tray 130 is installed on the guide rail 160, and the tray 130 is smaller in size, lighter in weight, and is not easy to be blocked, so it is easier to operate and install in place when assembled with the guide rail 160.

In addition, the deformation amount of the flange 150 in the height direction is substantially zero, which can ensure the fit and abutment with the seal 30, thereby ensuring the sealing effect.

When the drawer assembly 10 carries a weight of 25 kg, the deformation of the flange 150 in the height direction is substantially zero, that is, when the drawer assembly 10 bears the maximum load, the seal 30 can still fit and abut against the flange 150 to achieve a sealing effect.

[0118] like Figure 2 In some embodiments, a sealing groove 220 for installing the sealing member 30 is provided on the second mating surface.

[0119] It should be noted that the sealing member 30 and the sealing groove 220 are interference fit.

[0125] like Figure 1 As shown, the drawer structure includes a drawer assembly 10, an upper cover 20 and a sealing member 30; the drawer assembly 10 is movably arranged in the refrigerator body 40, the drawer assembly 10 includes a storage cavity 110 with a top opening, and a first mating surface 120 is arranged on the top of the drawer assembly 10; the upper cover 20 is arranged in the refrigerator body 40, a second mating surface is arranged on the bottom of the upper cover 20, and the upper cover 20 closes the opening of the storage cavity 110; the sealing member 30 is arranged on the second mating surface, the sealing member 30 abuts against the first mating surface 120 and surrounds the storage cavity 110; wherein, the first mating surface 120 is parallel to the second mating surface, a preset angle is arranged between the first mating surface 120 and the moving direction of the drawer assembly 10, and a side of the first mating surface 120 close to the refrigerator door is higher than a side of the first mating surface 120 away from the refrigerator door.

[0126] As can be seen from the above, by setting an upper cover 20 at the top of the storage cavity 110 to close the opening of the storage cavity 110, and setting a sealing member 30 around the storage cavity 110 between the upper cover 20 and the drawer assembly 10, the drawer assembly 10 is sealed, and the airflow inside and outside the drawer assembly 10 is effectively blocked, thereby enhancing the thermal insulation performance of the drawer assembly 10; by setting an inclined first mating surface 120 and a second mating surface, the drawer assembly 10 and the upper cover 20 are both in a high front and low back form, which not only reduces the sense of obstruction between the drawer assembly 10 and the sealing strip, facilitates the pulling and pulling of the drawer assembly 10, and improves the user experience, but also can remind the user whether the drawer assembly 10 has returned to its position during the pulling and pulling process.

[0136] Compared with the existing drawer structure that directly installs the drawer 140 on the guide rail 160, the drawer 140 needs to be removed from the guide rail 160 before it can be taken out. In the present invention, the tray 130 is provided to support the drawer 140, and the tray 130 is used to drive the drawer 140 to move in the X direction, so that the drawer 140 can be taken out more conveniently. In addition, compared with the existing drawer structure, the tray 130 is installed on the guide rail 160, and the tray 130 is smaller in size, lighter in weight, and is not easy to be blocked, so it is easier to operate and install in place when assembled with the guide rail 160.
