As in the application, for the convenience of description, when the refrigeration device is normally used, the direction towards the ground is downward, and the direction away from the ground is upward; the direction parallel to the ground is horizontal, and the direction perpendicular to the ground is vertical; the side close to the user is the front side, and the side away from the user is the rear side.

[0029] Reference Figures 1 to 8bAs shown, the preferred embodiment of the present application provides a refrigerator with ice storage function, the ice storage box 50 of the refrigerator can be used to store ice cubes or other objects placed in the refrigerator, after the refrigerator door 20 is opened, the ice storage box 50 extends out of the ice storage compartment 10, facilitating the user to take and place the ice cubes or objects in the ice storage box 50.

[0030] In addition, when the ice storage box 50 is used to place and store ice cubes, it can also be used in cooperation with the corresponding ice making device, that is, after the ice making device completes ice making, the ice cubes are automatically poured into the ice storage box 50, after the refrigerator door 20 is opened, the ice storage box 50 extends out of the ice storage compartment 10, facilitating the user to take and place the ice cubes in the ice storage box 50. In order to cooperate with the ice making device, the ice making device can be arranged in the ice storage compartment 10 and placed above the ice storage box 50, so as to ensure that the ice cubes made by the ice making device fall into the ice storage box 50.

[0031] For reference Figure 1 And Figure 2 As shown, the preferred embodiment of the present application provides a refrigerator with ice storage function, including an ice storage compartment 10 and a door 20 for opening and closing the ice storage compartment 10, the refrigerator further includes a pivot shaft 30 rotating with the opening and closing of the door 20. In this embodiment, the pivot shaft 30 can rotate with the opening and closing of the door 20, that is, the pivot shaft 30 can rotate with the rotation of the refrigeration equipment door 20, or the pivot shaft 30 can rotate with the rotation of the door 20 through a transmission member.

[0032] Further, the refrigerator further includes a rotating output shaft 40 in transmission connection with the pivot shaft 30 and arranged in the ice storage compartment 10. In this embodiment, the rotating output shaft 40 is arranged in the ice storage compartment 10 through a shaft sleeve or a bearing seat. The door 20 drives the pivot shaft 30 to rotate, and then the pivot shaft 30 drives the rotating output shaft 40 to rotate through transmission.

[0033] Further, one end of the rotating output shaft 40 is connected with an ice storage box 50. In this embodiment, the rotating output shaft 40 can be directly fixedly connected with the ice storage box 50, so that the ice storage box 50 rotates around the axis of the rotating output shaft 40.

[0034] Specifically, when the door 20 is opened, the pivot shaft 30 rotates and drives the ice storage box 50 to rotate through the rotating output shaft 40, so that at least part of the ice storage box 50 extends out of the ice storage compartment 10. In this embodiment, by arranging the rotating output shaft 40 in the ice storage compartment 10, the rotating output shaft 40 is driven by the pivot shaft 30 and drives the ice storage box 50 to rotate, so that when the refrigerator door 20 is opened, the ice storage box 50 rotates and at least part of it extends out of the ice storage compartment 10, making the ice taking process more convenient and improving the user's experience.

[0035] Further, the rotation axis of the rotating output shaft 40 is arranged along a vertical direction. In this embodiment, the ice storage box 50 is fixedly connected to the rotating output shaft 40, and can rotate along the axis of the rotating output shaft 40 in a horizontal plane to realize that at least part of the ice storage box 50 extends out of the ice storage chamber 10. Of course, the rotation axis of the rotating output shaft 40 can also be arranged along a horizontal direction, and at this time the ice storage box 50 rotates along the axis of the rotating output shaft 40 in a vertical plane to realize that at least part of the ice storage box 50 extends out of the ice storage chamber 10, and at this time the rotating output shaft 40 is arranged on the side wall of the ice storage box 50.

[0036] Continuing to refer to the accompanying drawings Figure 3 Specifically, the ice storage box 50 has a bottom wall 51 at the lower part thereof, the ice storage chamber 10 has a lower side wall 11 at the lower part thereof, and the rotating output shaft 40 is arranged between the bottom wall 51 and the lower side wall 11. In this embodiment, in order to save the internal space of the ice storage chamber 10, the bottom wall 51 of the ice storage box 50 can be attached to the lower side wall 11 of the ice storage chamber 10. Of course, the rotating output shaft 40 can also be rotatably arranged on the heat preservation partition plate or other mounting plane in the ice storage chamber 10.

[0037] Continuing to refer to the accompanying drawings Figure 4a An embodiment of the ice storage box 50 is provided, in order to realize that the ice storage box 50 and the rotating output shaft 40 are separable, and to facilitate the cleaning, maintenance and replacement of the ice storage box 50 later, a box body rotating hole 40a can be arranged on the bottom wall 51 of the ice storage box 50, and the rotating output shaft 40 is inserted into the box body rotating hole 40a. Among them, the box body rotating hole 40a is arranged as a regular polygon, and the rotating output shaft 40 is correspondingly arranged as a matching regular polygon.

[0038] Continuing to refer to the accompanying drawings Figure 4b Another embodiment of the ice storage box 50 is provided, in order to realize that the ice storage box 50 is detached from the ice storage chamber 10, and there is no protruding rotating output shaft 40 in the ice storage chamber 10, a box body rotating shaft 40b can also be arranged on the bottom wall 51 of the ice storage box 50, and then the box body rotating shaft 40b is connected with the rotating output shaft 40. In addition, the box body rotating shaft 40b can also replace the rotating output shaft 40 to be directly connected with the pivot 30. In this embodiment, when the ice storage box 50 is taken out of the ice storage chamber 10, there is no protrusion on the lower side wall 11 of the ice storage chamber, and other objects or other components can be placed.

[0039] Further, the axis of the pivot 30 and the axis of the rotating output shaft 40 are parallel to each other, and the refrigerator further comprises a transmission mechanism 60 for transmitting the pivot 30 and the rotating output shaft 40. In this embodiment, the transmission mechanism 60 between the pivot 30 and the rotating output shaft 40 can be gear transmission, chain transmission, belt transmission, as long as it can drive the rotating output shaft 40 to rotate.

[0040] Specifically, the rotation direction of the pivot 30 is consistent with the rotation direction of the rotation output shaft 40 after the transmission of the transmission mechanism 60. In this embodiment, since the rotation direction of the pivot 30 is the same as the rotation direction of the door body 20, the rotation direction of the rotation output shaft 40 is also the same as the rotation direction of the door body 20, so the rotation direction of the ice storage box 50 is also the same as the rotation direction of the door body 20. In this way, the rotation direction of the door body 20 when it is opened is the same as the rotation direction of the ice storage box 50 when it is rotated out of the ice storage compartment 10, avoiding the contact or collision between the door body 20 and the ice storage box 50 during the opening and closing process of the door body 20.

[0041] Specifically, continuing to refer to Figure 5 , the transmission mechanism 60 includes a first transmission gear 61 connected to the pivot 30 and a second transmission gear 63 connected to the rotation output shaft 40. In this embodiment, since the axis of the pivot 30 and the axis of the rotation output shaft 40 are parallel to each other, the first transmission gear 61 and the second transmission gear 63 can be set as intermeshing bevel gears. Of course, the first transmission gear 61 and the second transmission gear 63 can also be set as intermeshing spur gears, as long as they can ensure that the rotation direction of the pivot 30 is consistent with the rotation direction of the rotation output shaft 40 after the transmission of the transmission mechanism 60.

[0042] In addition, the number of teeth of the first transmission gear 61 is greater than the number of teeth of the second transmission gear 63. In this embodiment, since the rotation angle of the door body 20 is smaller than the rotation angle of the ice storage box 50, in order to ensure that the ice storage box 50 can reach the required rotation angle after the door body 20 rotates to the limit angle, the number of teeth of the first transmission gear 61 is set to be greater than the number of teeth of the second transmission gear 63 under the condition that the other gear parameters of the first transmission gear 61 and the second transmission gear 63 are the same. In this way, during the linkage process of the door body 20 and the ice storage box 50, it can be ensured that the ice storage box 50 rotates a larger angle relative to the angle of the door body 20 after the door body 20 rotates a certain angle.

[0043] Further, the rotation output shaft 40 is arranged in the symmetrical plane symmetrical to the left and right sides of the lower side wall 11. In this embodiment, when the rotation output shaft 40 is arranged in the symmetrical plane symmetrical to the left and right sides of the lower side wall 11, the ice storage box 50 can rotate more than 180° in the ice storage compartment 10.

[0044] Continuing to refer to Figure 6a and Figure 6b , at this time, the rotation output shaft 40 is not only in the symmetrical plane symmetrical to the left and right sides of the lower side wall 11, but also in the symmetrical plane symmetrical to the left and right sides of the bottom wall 51. This mode can not only satisfy the rotation of the ice storage box 50 more than 180° in the ice storage compartment 10, but also ensure the maximum area of the bottom wall 51, thereby storing more ice blocks.

[0045] The application further provides another preferred embodiment as a further improvement of the application, which will be described in combination with reference to Figure 5 Further, the transmission mechanism 60 further comprises a third transmission gear 65 matched with the first transmission gear 61, a fourth transmission gear 67 matched with the second transmission gear 63, and a transmission shaft 69 on which the third transmission gear 65 and the fourth transmission gear 67 are installed, wherein the number of teeth of the third transmission gear 65 is equal to that of the fourth transmission gear 67. In this embodiment, since there is a certain distance between the pivot 30 and the rotating output shaft 40, the first transmission gear 61, the second transmission gear 63, the third transmission gear 65 and the fourth transmission gear 67 in the transmission mechanism 60 are all bevel gears. In addition, in order to ensure that the transmission ratio between the pivot 30 and the rotating output shaft 40 does not change, the number of teeth of the third transmission gear 65 and the fourth transmission gear 67 can be set to the same number, and the other parameters of the gears are also kept the same.

[0046] Further, the refrigerator further comprises a shell 70 and an inner container 80 located inside the shell 70, wherein the ice storage compartment 10 is formed in the inner container 80, and the refrigerator further comprises a mounting bracket 90 arranged between the shell 70 and the ice storage compartment 10 and accommodating the transmission mechanism 60. In this embodiment, in order not to reduce the storage capacity of the ice storage compartment 10, the entire mounting bracket 90 is arranged in the foaming material between the shell and the inner container 80.

[0047] The application further provides another preferred embodiment as a further improvement of the application, which will be described in combination with reference to Figure 7 As shown in the figure, the refrigerator further comprises a clutch shaft 110 connected with the pivot 30. In this embodiment, the clutch shaft 110 is arranged to achieve the selectable disengagement transmission between the pivot 30 and the rotating output shaft 40, that is, the linkage between the door body 20 and the ice storage box 50 can be selectively closed.

[0048] Specifically, in combination with reference to Figure 8a and Figure 8b The first transmission gear 61 is arranged on the clutch shaft 110, and one end of the clutch shaft 110 abuts against a cam block 120.

[0049] In this embodiment, one end of the cam block 120 is connected with a driving shaft 120c, and the driving shaft 120c is rotatably arranged on the shell 70 or the mounting bracket 90 through a shaft sleeve or a bearing seat, so that the driving shaft 120c does not change its position in addition to its rotation. Since the cam block 120 is arranged at the end of the driving shaft 120c, the cam block 120 also does not change its position in addition to its rotation during the rotation. In addition to its rotation, the position of the cam block 120 always remains unchanged.

[0050] The cam block 120 has a first abutting surface 120a parallel to the axis of the driving shaft 120c, a second abutting surface 120b adjacent to the first abutting surface 120a and parallel to the axis of the driving shaft 120c, and the distance between the first abutting surface 120a and the axis of the driving shaft 120c is smaller than the distance between the second abutting surface 120b and the axis of the driving shaft 120c.

[0051] Further, after the rotation of the cam block 120, the clutch shaft 110 is driven to displace along the axis direction, and the first transmission gear 61 is driven to disengage. In the embodiment, when the surface abutting against the clutch shaft 110 is switched from the first abutting surface 120a to the second abutting surface 120b, the distance between the clutch shaft 110 and the axis of the driving shaft 120c is increased. Since the driving shaft 120c and the cam block 120 do not displace, the clutch shaft 110 is driven to displace in the direction away from the driving shaft 120c, so that the first transmission gear 61 and the third transmission gear 65 disengage, and then the door body 20 and the ice storage box 50 disengage.

[0052] Specifically, the first abutting surface 120a is a planar structure, and the second abutting surface 120b is an arc surface structure. In the embodiment, since the second abutting surface 120b is provided as an arc surface structure, the switching of the surface abutting against the clutch shaft 110 from the first abutting surface 120a to the second abutting surface 120b is smoother, the user can operate the rotation of the cam block 120 more easily, and the operation of the user is facilitated.

[0053] In addition, in order to facilitate the user to operate the rotation of the driving shaft 120c, an operation handle 120d can also be arranged at the other end of the driving shaft 120c relative to the cam block 120, and the operation handle 120d is arranged outside the refrigerator shell 70. In order to disengage the door body 20 and the ice storage box 50, the user only needs to operate the operation handle 120d outside the refrigerator shell 70.

[0054] The application also provides another preferred embodiment, which is a further improvement of the application, and is described with reference to the accompanying drawings Figure 7 As shown in the drawings, the refrigerator further comprises a connecting seat 130 connecting the pivot 30 and the clutch shaft 110, an elastic member 140 sleeved on the clutch shaft 110 and abutting between the connecting seat 130 and the first transmission gear 61, and the clutch shaft 110 is in transition fit with the connecting seat 130.

[0055] In this embodiment, the elastic member 140 provides a pre-tightening force to the first transmission gear 61 towards the driving shaft 120c, on the one hand, so that the first transmission gear 61 and the third transmission gear 65 are better engaged; on the other hand, when the face abutting against the clutch shaft 110 is switched from the second abutting face 120b to the first abutting face 120a, the elastic member 140 drives the clutch shaft 110 to displace towards the driving shaft 120c, so that the first transmission gear 61 and the third transmission gear 65 are restored to engagement.

[0056] Therefore, after the cam block 120 cooperates with the elastic member 140, the whole scheme can not only drive the first transmission gear 61 and the third transmission gear 65 to disengage, but also restore the transmission connection between the first transmission gear 61 and the third transmission gear 65, so as to selectively engage or disengage the first transmission gear 61 and the third transmission gear 65, that is, the linkage between the door body 20 and the ice storage box 50 can be selectively opened or closed.

[0057] In addition, in order to meet the axial pressure required for the engagement between the first transmission gear 61 and the third transmission gear 65, the elastic member 140 is preferably a disc spring.

[0058] Specifically, the clutch shaft 110 also has a limiting block 110c adjacent to the clutch shaft mounting portion 110a and close to the side of the cam block 120, one end of the first transmission gear 61 abuts against the limiting block 110c, and the other end abuts against the elastic member 140. After the relative rotation of the cam block 120, the elastic member 140 drives the first transmission gear 61 to displace towards the driving shaft 120c and engage with the third transmission gear 65. In this embodiment, the limiting block 110c limits the displacement of the first transmission gear 61 towards the driving shaft 120c, and also drives the whole clutch shaft 110 to displace towards the driving shaft 120c when the first transmission gear 61 displaces towards the driving shaft 120c.

[0059] In this embodiment, the transmission connection between the pivot shaft 30 and the clutch shaft 110 is achieved by the connecting seat 130. Of course, a transmission assembly can also be used to achieve the transmission connection between the pivot shaft 30 and the clutch shaft 110.

[0060] Specifically, one end of the elastic member 140 abuts against the first transmission gear 61, and the other end abuts against the connecting seat 130. In this embodiment, the connecting seat 130 has a boss with an outer diameter larger than that of the elastic member 140, which is used to abut against the elastic member 140.

[0061] Specifically, the pivot 30 is fixedly connected with the connecting seat 130, and the clutch shaft mounting portion 110a is transitionally matched with the connecting seat 130. In the embodiment, since the clutch shaft mounting portion 110a is transitionally matched with the connecting seat 130, the clutch shaft mounting portion 110a can be axially displaced in the connecting seat 130, and then the whole clutch shaft 110 can be axially displaced in the connecting seat 130, so as to meet the condition that the first transmission gear 61 and the third transmission gear 65 can be in clutching or disengaging.

[0062] Further, the clutch shaft 110 further has a clutch shaft driving portion 110b adjacent to the limiting block 110c and close to one side of the cam block 120, and an arc-shaped chamfer is arranged at the end of the clutch shaft driving portion 110b away from the limiting block 110c, and the cam block 120 abuts against the arc-shaped chamfer. In the embodiment, when the first abutting surface 120a abuts against the clutch shaft driving portion 110b, the first transmission gear 61 and the third transmission gear 65 are in meshing with each other, and when the second abutting surface 120b abuts against the clutch shaft driving portion 110b, the first transmission gear 61 and the third transmission gear 65 are disengaged. Therefore, the clutch shaft driving portion 110b always abuts against the cam block 120, and the end thereof is arranged as an arc-shaped chamfer, so as to reduce the contact area between the clutch shaft driving portion 110b and the cam block 120, thereby reducing the friction force between the clutch shaft driving portion 110b and the cam block 120, reducing the resistance brought by the cam block 120 to the rotation of the pivot 30, so as not to affect the user to normally open or close the door body of the refrigeration equipment.

[0063] It should be understood that, although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the specification is described in this way only for the sake of clarity, and those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that those skilled in the art can understand.

[0064] The series of detailed descriptions listed above are only specific descriptions of the feasible embodiments of the present application, and are not used to limit the protection scope of the present application, and equivalent embodiments or changes made without departing from the spirit of the present application should be included in the protection scope of the present application.
