[0046] Figure 1 is a schematic structural diagram of a refrigeration and freezing device according to an embodiment of the present invention, Figure 1As shown, and refer to Figures 2 to 6 , an embodiment of the present invention provides a refrigeration and freezing device 100, comprising a box body 110, two door bodies and a first sealing beam 130. The box body 110 is formed with a first storage compartment 111. The two door bodies are arranged opposite to each other and configured to open or close the first storage compartment 111. The first sealing beam 130 is arranged at the opening of the first storage compartment 111 and is configured to seal at least a portion of the gap between the two door bodies. The first sealing beam 130 is movably arranged in a direction perpendicular to the first sealing beam 130, and the first sealing beam 130 can be moved to a first position directly opposite to the gap between the two door bodies, and to a second position away from the first position.

[0047] In the refrigeration and freezing device 100 of the embodiment of the present invention, since the first sealing beam 130 is arranged on the box body 110 instead of the door body, it can be avoided that the door body is opened or closed with excessive force, resulting in the problem of abnormal noise in the door body during the opening and closing process. In addition, since the first sealing beam 130 is movably arranged, before closing the two door bodies, the first sealing beam 130 is moved to the first position directly opposite to the first sealing beam 130, and the first sealing beam 130 can close the gap between the two door bodies, realize the sealing of the first storage compartment 111, and prevent the cold amount in the first storage compartment 111 from leaking. After opening the two door bodies, the first sealing beam 130 can be moved to the second position, so that the first sealing beam 130 does not block the opening of the first storage compartment 111, and it is convenient to take and put the wider items in the first storage compartment 111 through the opening, which meets the user's use requirements and improves the user's use experience. The refrigeration and freezing device 100 in this embodiment can meet both the sealing requirements and the requirements of taking and putting wider items.

[0048] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the two doors include a first door 121 and a second door 122. The refrigerator 100 further includes a linkage device 140, which is configured to move the first sealing beam 130 to a first position when the first door 121 is closed, and to move the first sealing beam 130 to a second position when the first door 121 is opened.

[0049] In this embodiment, when the first door body 121 is closed, the first sealing beam 130 automatically moves to the first position under the action of the linkage device 140, closing the gap between the first door body 121 and the second door body 122, and when the first door body 121 is opened, the first sealing beam 130 automatically moves to the second position under the action of the linkage device 140, so that the opening of the first storage compartment 111 is larger, which is convenient for taking and placing wider items in the first storage compartment 111. Due to the provision of the linkage device 140, the movement of the first sealing beam 130 can be achieved while opening and closing the first door body 121, thereby achieving the requirements of sealing and facilitating the taking and placing of items. In this embodiment, the first sealing beam 130 does not need to be moved manually, and the movement of the first sealing beam 130 can be achieved by completing the normal door opening and closing action, making the operation simple and convenient.

[0050] In some embodiments of the present invention, when the first door 121 is opened, the first sealing beam 130 moves to one side of the opening of the first storage compartment 111 .

[0051] In this embodiment, since the first sealing beam 130 is moved to one side of the opening of the first storage compartment 111, the first sealing beam 130 does not block the opening of the first storage compartment 111, thereby making it more convenient to take in and out wider items.

[0052] In some embodiments of the present invention, the linkage device 140 includes an external transmission device and an internal transmission device. The external transmission device is disposed outside the first storage compartment 111 and is configured to output a rotational motion having an angular velocity greater than the rotation of the first door body 121. The internal transmission device is disposed in a compartment wall of the first storage compartment 111 and is configured to convert the rotational motion output by the external transmission device into movement of the first sealing beam 130.

[0053] In this embodiment, the external transmission device increases the angular velocity of the rotation of the first door body 121 and outputs it to the outside, which plays an accelerating role, while the internal transmission device converts the rotational motion output by the external transmission device into the movement of the first sealing beam 130. The external transmission device cooperates with the internal transmission device to accelerate the rotational motion of the first door body 121 and convert it into the movement of the first sealing beam 130. This arrangement allows the first door body 121 to rotate a smaller angle, and the first sealing beam 130 can move a longer distance, thereby making the rotation range of the first door body 121 unnecessary to be too large, so that the refrigeration and freezing device 100 occupies a smaller space. In addition, since the external transmission device is arranged outside the first storage compartment 111, the external transmission device does not occupy the space of the first storage compartment 111, so that the first storage compartment 111 can store more items.

[0054] In some embodiments of the present invention, Figures 2 to 5As shown, the external transmission device includes a first pulley transmission device and a second pulley transmission device. The first pulley transmission device includes a first pulley 141, a second pulley 142 and a first transmission belt, and a first conveyor belt 143 is sleeved on the first pulley 141 and the second pulley 142. The first pulley 141 is arranged on the first door body 121 and is coaxially arranged with the rotating shaft of the first door body 121. The second pulley 142 is rotatably arranged on the outer wall of the first storage compartment 111. The second pulley transmission device is arranged on the outer wall of the first storage compartment 111, and includes a third pulley 144, a fourth pulley 145 and a second transmission belt, and a second conveyor belt 146 is sleeved on the third pulley 144 and the fourth pulley 145. The third pulley 144 is connected to the second pulley 142 and is coaxially arranged with the second pulley 142. The diameter of the first pulley 141 is greater than or equal to the diameter of the second pulley 142, and the diameter of the second pulley 142 is less than the diameter of the third pulley 144. Among the first pulley 141 , the second pulley 142 , the third pulley 144 and the fourth pulley 145 , the third pulley 144 has the largest diameter, and the fourth pulley 145 has the smallest diameter.

[0055] In this embodiment, the working process of the first conveyor belt 143 device and the second conveyor belt 146 device is as follows: the rotating shaft of the first door body 121 rotates around its own axis, and the rotating shaft drives the first pulley 141 to rotate. The first pulley 141 drives the second pulley 142 to rotate through the first conveyor belt 143. The third pulley 144 rotates synchronously with the drive of the second pulley 142. The third pulley 144 drives the fourth pulley 145 to rotate through the second conveyor belt 146.

[0056] Since the first pulley 141 and the second pulley 142 are connected by the first conveyor belt 143, and the third pulley 144 and the fourth pulley 145 are connected by the second conveyor belt 146, the linear velocity of the first pulley 141 is the same as the linear velocity of the second pulley 142, and the linear velocity of the fourth pulley 145 is equal to the linear velocity of the third pulley 144. Since the second pulley 142 and the third pulley 144 are coaxially arranged, the angular velocities of the second pulley 142 and the third pulley 144 are equal. The diameter of the first pulley 141 is greater than or equal to the diameter of the second pulley 142, so that the angular velocity of the second pulley 142 is greater than or equal to the angular velocity of the first pulley 141, and the diameter of the second pulley 142 is smaller than the diameter of the third pulley 144, so that the linear velocity of the third pulley 144 is greater than the linear velocity of the second pulley 142. In this embodiment, by providing the first pulley 141, the second pulley 142, the third pulley 144 and the fourth pulley 145, a larger displacement of the first sealing beam 130 can be achieved through a smaller rotation angle of the door body, that is, the first pulley transmission device and the second pulley transmission device cooperate to have an acceleration function. The second pulley 142 with the largest diameter is provided on the box body 110 instead of the door body, so that an installation space can be provided for the second pulley 142.

[0057] In some embodiments of the present invention, Figure 4 and Figure 5 As shown, the internal transmission device is a gear rack transmission device, which includes a gear 147 and a rack 148 meshing with the gear 147. The gear 147 is connected to the fourth pulley 145 and is coaxially arranged with the fourth pulley 145. The rack 148 extends along the direction in which the first sealing beam 130 moves, and the rack 148 is connected to the first sealing beam 130.

[0058] In this embodiment, the fourth pulley 145 drives the gear 147 to rotate, so that the rack 148 moves under the action of the gear 147, thereby driving the first sealing beam 130 to move, thereby achieving the function of sealing the door body or taking and placing items. The gear 147 rack 148 mechanism in this embodiment has a simple structure, is easy to design and manufacture, and has a low cost.

[0059] In some embodiments of the present invention, the gear 147 is connected to the fourth pulley 145 via a transmission shaft, and the transmission shaft passes through a side wall of the first storage compartment 111 .

[0060] In this embodiment, the connection between the outer transmission device and the inner transmission device can be realized by only one transmission shaft, so as to achieve the purpose of transmission, thereby making the structure simple and the cost low. Moreover, since the contact area between the transmission shaft and a side wall of the first storage compartment is small, a better sealing effect can be achieved to prevent the cold in the first storage compartment from leaking through the gap between the transmission shaft and the side wall of the first storage compartment. For example, a sealing structure such as a sealing ring can be provided at the gap between the transmission shaft and the side wall of the first storage compartment to achieve a better sealing effect.

[0061] In some embodiments of the invention, the first pulley transmission is driven by a friction belt.

[0062] In this embodiment, the first conveyor belt 143 is a flat conveyor belt, the first pulley 141 and the second pulley 142 are smooth pulleys, and the first pulley 141, the second pulley 142 and the first conveyor belt 143 are driven by friction. This arrangement makes the first pulley transmission device low in noise during operation, and has the advantages of simple structure, easy design and manufacturing, and low cost.

[0063] In some embodiments of the present invention, the first pulley transmission is driven by a synchronous belt.

[0064] In this embodiment, the first conveyor belt 143 is a synchronous conveyor belt, and the first pulley 141 and the second pulley 142 are synchronous pulleys. Specifically, the inner circumference of the synchronous conveyor belt is provided with a tooth groove, and the outer circumference of the first pulley 141 and the second pulley 142 are provided with gear teeth. When working, the tooth groove on the synchronous conveyor belt meshes with the gear teeth on the first pulley 141 and the second pulley 142 to transmit motion and power. The cooperation between the synchronous conveyor belt and the first pulley 141 and the second pulley 142 has the advantages of accurate transmission, stability, shock absorption and low noise.

[0065] In some embodiments of the invention, the second pulley transmission is driven by a friction belt.

[0066] In some embodiments of the present invention, the second pulley transmission is driven by a synchronous belt.

[0067] In some other embodiments of the present invention, the external transmission device includes a first pulley transmission device. The first pulley transmission device includes a first pulley, a second pulley and a first transmission belt, and the first transmission belt 143 is sleeved on the first pulley and the second pulley. The first pulley is arranged on the first door body 121 and is coaxially arranged with the rotating shaft of the first door body 121. The second pulley is rotatably arranged on the outer wall of the first storage compartment 111. The second pulley transmission device is arranged on the outer wall of the first storage compartment 111. The diameter of the first pulley is greater than the diameter of the second pulley. The gear 147 is connected to the second pulley and is coaxially arranged with the second pulley.

[0068] In this embodiment, the linkage between the first sealing beam 130 and the door body is realized by setting the first pulley transmission device and the gear rack transmission device, and the first pulley transmission device and the gear rack transmission device have simple structures, are easy to design and manufacture, and have low cost. In addition, since the first pulley and the second pulley are connected by the first conveyor belt 143, and the diameter of the first pulley is greater than the diameter of the second pulley, the linear speeds of the first pulley and the second pulley are equal, while the angular speed of the second pulley is greater than the angular speed of the first pulley, that is, in the same time, the second pulley rotates more times. In this way, when the door body is opened at a smaller angle, the first sealing beam 130 can achieve a larger displacement, thereby reducing the rotation angle of the door body when it is opened, and thereby reducing the occupied space of the refrigeration and freezing device 100.

[0069] In some embodiments of the present invention, Figure 4 and Figure 5As shown, a slide groove 151 and a mounting groove are provided on the compartment wall of the first storage compartment 111 where the internal transmission device is provided. The slide groove 151 extends along the moving direction of the first sealing beam 130, and a communication port communicating with the mounting groove is provided on one side wall of the slide groove 151 along the length direction. The rack 148 is slidably provided in the slide groove 151, and the gear 147 is installed in the mounting groove, and a portion of the gear 147 passes through the communication port and meshes with the rack 148.

[0070] In this embodiment, the slide groove 151 is provided to facilitate the rack 148 to slide along the length direction of the slide groove 151 , thereby limiting the movement of the rack 148 in other directions, thereby ensuring the moving direction of the first sealing beam 130 .

[0071] In other embodiments of the present invention, Figure 4 and Figure 5 As shown, a mounting groove is provided on the compartment wall of the first storage compartment 111 where the internal transmission device is provided, a mounting notch is formed at one edge of the opening of the first storage compartment 111, a mounting box 150 is provided in the mounting notch, and a slide groove 151 is formed in the mounting box 150. The slide groove 151 extends along the moving direction of the first sealing beam 130, and a communication port communicating with the mounting groove is provided on one side wall of the slide groove 151 along the length direction.

[0072] In this embodiment, the slide groove 151 is provided to facilitate the sliding of the rack 148 along the length direction of the slide groove 151, thereby limiting the movement of the rack 148 in other directions, thereby ensuring the moving direction of the first sealing beam 130. The installation box 150 is detachable, which is convenient for replacing the installation box 150.

[0073] In some embodiments of the present invention, Figure 5 As shown, the refrigerator-freezer 100 further includes a guide rod 160, which is disposed in the slide slot 151 and extends along the length direction of the slide slot 151. The first sealing beam 130 is provided with a guide slot, and the guide rod 160 is inserted into the guide slot.

[0074] In this embodiment, the guide groove on the first sealing beam 130 cooperates with the guide rod 160 to guide the movement of the first sealing beam 130 .

[0075] In some other embodiments of the present invention, a guide groove is formed on the rack 148, and the guide rod 160 is inserted into the guide groove.

[0076] In this embodiment, since the rack 148 is connected to the first sealing beam 130 , the guide groove on the rack 148 cooperates with the guide rod 160 to guide the movement of the rack 148 and further guide the movement of the first sealing beam 130 .

[0077] In some embodiments of the present invention, Figure 2and Figure 3 As shown, taking the opening of the first storage compartment 111 facing forward as an example, at least one horizontally arranged shelf 112 may be arranged in the first storage compartment 111, and the shelf 112 may divide the first storage space into two small storage compartments, and items may be placed on the shelf 112. Furthermore, the two side walls of the first storage compartment 111 are provided with card slots extending in the front-to-back direction, and the lateral ends of the shelf 112 are inserted into the card slots to complete the installation and fixation of the shelf 112. Card slots of different heights may be arranged on the two side walls of the first storage compartment 111 for the installation of the shelf 112, and the height of the shelf 112 may be adjusted to meet the different usage requirements of users.

[0078] In some embodiments of the present invention, Figure 6 As shown, the first sealing beam 130 includes a mounting block 131 and a main body section 132 connected to each other, one end of the mounting block 131 is connected to the rack 148 , and the other end of the mounting block 131 is detachably connected to the upper end of the main body section 132 .

[0079] In this embodiment, since the mounting block 131 and the main section 132 of the first sealing beam 130 are detachably connected, the main section 132 can be removed from the mounting block 131, and then the user can pull the partition outward and pull it out of the first storage compartment 111, and then install the shelf 112 in a slot of other heights as needed to adjust the height of the shelf 112.

[0080] In some embodiments of the present invention, the mounting block 131 and the main body section 132 may be connected by screws, so that the user can remove the main body section 132 from the mounting block 131 .

[0081] In some embodiments of the present invention, Figure 1 As shown, the first storage compartment 111 has an opening facing forward, and the first sealing beam 130 is vertically arranged at the opening of the first storage compartment 111. The box body 110 is also formed with a second storage compartment having an opening facing forward. The second storage compartment is located below the first storage compartment 111. The refrigeration and freezing device 100 also includes a drawer 170 and a second sealing beam 180. The drawer 170 is arranged in a push-pull manner in the second storage compartment. The second sealing beam 180 is arranged at the front end of the drawer 170 to form a handle of the drawer 170. The second sealing beam 180 is vertically arranged and is configured to seal other sections of the gap between the two door bodies. When the first sealing beam 130 and the second sealing beam 180 are both moved to the first position, the lower end surface of the first sealing beam 130 contacts the upper end surface of the second sealing beam 180.

[0082] In this embodiment, when closing the two door bodies, first push the drawer 170 into the second storage room, move the first sealing beam 130 to the first position, and make the vertical axis of the first sealing beam 130 coincide with the vertical axis of the second sealing beam 180, so as to seal the gap between the two door bodies after the two door bodies are closed. After opening the two door bodies, move the first sealing beam 130 to the second position, which can facilitate the access to wider items in the first storage room 111. At the same time, the drawer 170 can also be pulled out to access items in the second storage room. In other words, the first sealing beam 130 and the second sealing beam 180 are used together to seal the gap between the two door bodies to prevent the loss of cold, and the movements of the first sealing beam 130 and the second sealing beam 180 do not affect each other. The first sealing beam 130 moves along the lateral direction of the box body 110, while the second sealing beam 180 moves along the front-to-back direction. Furthermore, the second sealing beam 180 can also serve as a handle of the drawer 170, so that the user can push and pull the drawer 170 without providing a handle, thereby simplifying the structure, saving materials and reducing costs.

[0083] In some embodiments of the present invention, the lower end surface of the first sealing beam 130 is connected to the upper end surface of the second sealing beam 180 by magnetic attraction. The first sealing beam 130 is movably arranged in the area between the gap between the two door bodies and the edge of one side of the opening of the first storage compartment 111. The lower end surface of the first sealing beam 130 and the upper end surface of the second sealing beam 180 are both inclined surfaces to hinder the movement of the first sealing beam 130 to the area between the gap between the two door bodies and the edge of the other side of the opening of the first storage compartment 111.

[0084] In this embodiment, since the first sealing beam 130 and the second sealing beam 180 are connected by magnetic attraction, the lower end surface of the first sealing beam 130 and the upper end surface of the second sealing beam 180 are closely matched, which can prevent the formation of a gap between the first sealing beam 130 and the second sealing beam 180, thereby affecting the sealing effect of the gap between the two door bodies. Moreover, after the two door bodies are opened, the first sealing beam 130 is moved toward one lateral end of the box body 110 to overcome the magnetic attraction between the first sealing beam 130 and the second sealing beam 180, so that the lateral movement of the first sealing beam 130 along the box body 110 is not affected. Furthermore, the lower end surface of the first sealing beam 130 and the upper end surface of the second sealing beam 180 are both inclined surfaces, which not only makes the contact area between the first sealing beam 130 and the second sealing beam 180 larger and the magnetic attraction effect better, but the upper end surface of the second sealing beam 180 can also limit the lateral movement of the first sealing beam 130, so that the first sealing beam 130 can only move in the area between the gap between the two door bodies and the side edge of the opening of the first storage compartment 111.

[0085] In some embodiments of the present invention, the first sealing beam 130 and the second sealing beam 180 may be magnetically connected via a permanent magnet or an electromagnet, which may be selected according to needs.
