[0038] For air-cooled refrigerators, the cold air in the storage space flows along a certain path, and a temperature difference is easily generated between the position where the cold air can flow and the dead corner of the flow, which affects the storage effect of the refrigerator.

[0039] In order to improve the temperature uniformity inside an air-cooled refrigerator, a related art discloses an air-cooled refrigerator having a refrigerated compartment, the refrigerator comprising a refrigerated air duct and an air duct cover, the refrigerated air duct is provided with a refrigerated air supply port for supplying air to the refrigerated compartment, the air duct cover is provided with an air guide plate, the air guide plate guides the air flow out of the refrigerated air supply port to the side wall of the refrigerated compartment. The air guide plate is used to adjust the blowing direction of the cold air to avoid the cold air blowing directly on fruits and vegetables and other food materials, thereby improving the preservation effect of fruits and vegetables and other food materials. The problem with the related art is that the bidirectional swing of the air guide plate needs to be driven by the bidirectional rotation of the drive motor, and the cost of the air outlet device is relatively high.

[0040] The air outlet device for a refrigerator and the refrigerator provided in the embodiments of the present disclosure are conceived to drive the swing air component to reciprocate by a unidirectional motor, thereby reducing the cost of the air outlet device.

[0041] Combination Figure 1-5 As shown, the embodiment of the present disclosure provides an air outlet device for a refrigerator, which includes a driving column 110, a driving rod 120 and an air guide assembly 200, wherein the driving column 110 can rotate around the axial direction of the driving column 110, and a closed guide groove 111 is provided on the side of the driving column 110; the driving rod 120 is arranged along the radial direction of the driving column 110 and can slide along the axial direction of the driving column 110, one end of the driving rod 120 extends into the guide groove 111, and when the driving column 110 rotates, the driving rod 120 is driven to reciprocate along the axial direction of the driving column 110; the air guide assembly 200 is transmission-connected to the driving rod 120, and when the driving rod 120 reciprocates, it drives the air guide assembly 200 to swing back and forth.

[0042] In the disclosed embodiment, the driving column 110 drives the air guide assembly 200 to swing via the driving rod 120 .

[0043] Specifically, the driving column 110 is a rotating driving component that can rotate around its own axis. The driving column 110 has two end faces and a side surface for connecting the two end faces. A closed guide groove 111 is provided on the side surface of the driving column 110. The closed guide groove 111 means that the guide groove 111 is connected end to end. As an embodiment, the guide groove 111 is provided around the side surface of the driving column 110.

[0044] The driving rod 120 is arranged along a radial line of the driving column 110 and is slidable. The sliding direction of the driving column 110 is along the axial direction of the driving column 110. One end of the driving column 110 extends into the guide groove 111. When the driving column 110 rotates, the position of one end of the driving column 110 in the guide groove 111 changes, so that the driving column 110 moves along the axial direction.

[0045] In order to make the driving column 110 drive the driving rod 120 to slide, the distance between the guide groove 111 and one end surface of the driving column 110 changes continuously. Exemplarily, the guide groove 111 is formed in the side wall of the guide column in the shape of a sine curve or a cosine curve. When the guide column rotates, in each sine cycle or cosine cycle of the guide groove 111, the driving column 110 reciprocates along the axial direction of the guide groove 111 for one cycle.

[0046] The driving rod 120 is transmission-connected to the air guide assembly 200. With the reciprocating motion of the driving rod 120, the air guide assembly 200 swings back and forth to achieve uniform cooling and air discharge for the environment inside the refrigerator.

[0047] When the air outlet device provided by the embodiment of the present disclosure is used, when the driving column 110 rotates continuously in one direction, the driving rod 120 reciprocating along the axial direction of the driving column 110 drives the air outlet assembly to swing back and forth. In this way, a two-way drive of the air guide assembly 200 is realized by a unidirectional rotating motor, which simplifies the structure of the air outlet device and reduces the cost of the air outlet device.

[0048] Optionally, the air outlet device further includes a first track for limiting the movement of the driving rod 120 to a first plane.

[0049] The first track is provided to make the movement of the driving rod 120 more stable, so that the driving column 110 can better drive the driving rod 120 to swing back and forth.

[0050] Optionally, the air outlet device further includes a connecting rod 130 , which is disposed along the axial direction of the driving column 110 . When the driving rod 120 reciprocates, the connecting rod 130 drives the air guide assembly 200 to swing back and forth.

[0051] The driving rod 120 is arranged along a radial line of the driving column 110. When the driving rod 120 is directly connected to the air outlet assembly, the installation positions of the air guide assembly 200 and the driving column 110 are limited. Therefore, the air outlet assembly further includes a connecting rod 130, which is arranged along the axial direction of the driving column 110. With such an arrangement, on the one hand, the length directions of the driving column 110 and the connecting rod 130 are in the same direction, thereby reducing the space required for installing the air outlet assembly; on the other hand, the connecting rod 130 can connect multiple air outlet assemblies at the same time, further simplifying the structure of the air outlet assembly.

[0052] Optionally, the air outlet device further includes a second track for limiting the movement of the connecting rod 130 to a second plane.

[0053] The second track is provided to make the movement of the connecting rod 130 more stable, so that the driving rod 120 can better drive the air guide assembly 200 to swing through the connecting rod 130 .

[0054] Optionally, the air guide assembly 200 includes a first axle pin 231, an air guide cover 210 and a second axle pin 232, wherein the first axle pin 231 is arranged on the inner tank 10 of the refrigerator; the air guide cover 210 is rotatably arranged on the first axle pin 231; the second axle pin 232 is arranged on the air guide cover 210, and the connecting rod 130 is connected to the second axle pin 232 to be rotatably connected to the air guide cover 210.

[0055] The inner container 10 of the refrigerator is provided with an air outlet 11, and the first shaft pin 231 is arranged near the air outlet 11. The air guide cover 210 is rotatably connected to the first shaft pin 231 corresponding to the air outlet 11, and the air guide cover 210 changes the air outlet direction of the air outlet 11 when it rotates. In some cases, the first shaft pin 231 is fixed to the inner container 10 of the refrigerator, and the air guide cover 210 is rotatably connected to the first shaft pin 231; in other cases, the first shaft pin 231 is fixed to the air guide cover 210, and the first shaft pin 231 is rotatably connected to the inner container 10 of the refrigerator.

[0056] The second shaft pin 232 is provided on the air scoop 210, and the connecting rod 130 is connected to the second shaft pin 232 to be rotatably connected to the air scoop 210. The first shaft pin 231 and the second shaft pin 232 are provided in parallel, and when the connecting rod 130 moves along its length direction, it drives the air scoop 210 to rotate around the first shaft pin 231. In some cases, the second shaft pin 232 is fixed to the air scoop 210, and the connecting rod 130 is rotatably connected to the second shaft pin 232; in other cases, the second shaft pin 232 is fixed to the connecting rod 130, and the second shaft pin 232 is rotatably connected to the air scoop 210.

[0057] The air guide assembly 200 includes an air guide cover 210, which can not only change the air outlet direction, but also improve the gathering effect of the refrigeration air outlet. The first shaft pin 231 and the second shaft pin 232 are arranged to facilitate the connecting rod 130 to drive the air guide cover 210 to rotate relative to the refrigerator inner tank 10.

[0058] Optionally, the air guide assembly 200 further includes an air outlet duct 220 , which extends inward from the inner container 10 of the refrigerator. The first shaft pin 231 is disposed on the air outlet duct 220 , and at least a portion of the air guide cover 210 is sleeved on the air outlet duct 220 .

[0059] The refrigerator further includes an air outlet duct 220 , which is disposed corresponding to the air outlet 11 and extends from the inner container 10 of the refrigerator to the refrigerated space enclosed and defined by the inner container 10 .

[0060] Optionally, the air outlet device includes a plurality of air guide assemblies 200 , and the plurality of air guide assemblies 200 together limit the movement of the connecting rod 130 to a first plane.

[0061] The air outlet device includes a plurality of air outlet components. On the one hand, when a plurality of air outlets 11 are provided in the refrigerator inner tank 10, the temperature inside the refrigerator can be made more uniform by guiding the air through the plurality of air outlet components. On the other hand, the plurality of air outlet components are all provided with a second rotating shaft, so that the connecting rod 130 can be fixed better through a plurality of fixed points. The plane in which the connecting rod 130 moves has the axis of one of the second rotating shafts as the normal line. With such a setting form, not only can the temperature uniformity of the refrigerator be improved, but also the fixation of the connecting rod 130 can be simplified, which facilitates the setting of the air outlet component.

[0062] Optionally, the connecting rod 130 is fixedly connected to the driving rod 120 to limit the movement of the driving rod 120 to a second plane.

[0063] The connecting rod 130 is fixed by the second axle pins 232 of the multiple air outlet components, and the driving rod 120 is fixedly connected to the connecting rod 130, thereby being fixed in a plane. When the driving rod 120 and the connecting rod 130 are located in the same plane, the first plane and the second plane are the same plane; when the driving rod 120 and the connecting rod 130 are not located in the same plane, the first plane is parallel to the second plane. In the adopted setting form, the second axle pins 232 of the multiple air guide components 200 not only fix the connecting rod 130 but also fix the driving rod 120. That is, the driving rod 120 and the connecting rod 130 are both movably fixed to the multiple air guide components 200. This can further simplify the structure of the air outlet device and thus reduce the cost of the air outlet device.

[0064] Optionally, along the length direction of the guide groove 111 , the distance between the guide groove 111 and an end surface of the driving column 110 changes periodically.

[0065] The length direction of the guide groove 111 refers to the direction extending along the axis of the guide groove 111. The guide groove 111 is formed in the side wall of the driving column 110 in the shape of a sine curve or a cosine curve. When one end face of the driving column 110 is perpendicular to the axis of the driving column 110, the distances between different positions of the guide groove 111 and the end face of the driving column 110 continuously and periodically change, that is, they change back and forth along the axis of the driving column 110. When the driving column 110 rotates, the position of the driving rod 120 that matches the guide groove 111 changes, thereby reciprocating along the axial direction of the driving column 110 as the driving column 110 rotates.

[0066] With such a configuration, the rotation of the driving column 110 can drive the driving rod 120 to swing back and forth along the axial direction of the driving column 110, and then the air guide assembly 200 can swing back and forth through the connecting rod 130. The air guide assembly 200 can swing back and forth only by rotating the driving column 110 in one direction, thereby reducing the cost of the air outlet device.

[0067] Optionally, each time the driving post 110 rotates one circle, the distance between the guide groove 111 and an end surface of the driving post 110 changes in a cycle.

[0068] In this case, the driving rod 120 drives the air guide assembly 200 to swing back and forth once for each rotation of the driving column 110. On the one hand, the force required by the driving column 110 to drive the air guide assembly 200 to swing is relatively small, which is conducive to the driving column 110 driving the air guide assembly 200 to rotate; on the other hand, since there is a one-to-one correspondence between the rotation angle of the driving column 110 and the outlet angle of the air outlet assembly, such a setting form is conducive to controlling the outlet angle of the air outlet assembly by controlling the rotation angle of the driving column 110.

[0069] Optionally, a ball is provided at one end of the driving rod 120 extending into the guide groove 111 .

[0070] By adopting such a configuration, the friction between the driving rod 120 and the guide groove 111 can be reduced, thereby improving the driving smoothness of the driving column 110 for the air guide assembly 200 .

[0071] Optionally, along the length direction of the guide groove 111 , the depth of the guide groove 111 changes continuously.

[0072] During the swinging process of the connecting rod 130, the connecting rod 130 is rotated and connected to the second shaft pin 232, so the distance between the connecting rod 130 and the guide column also changes periodically. That is, during the rotation process of the driving column 110, the depth of the driving rod 120 extending into the guide groove 111 also changes periodically. The depth of the guide groove 111 changes continuously along the length direction of the guide groove 111, which is conducive to better cooperation between the guide groove 111 and the driving rod 120.

[0073] Optionally, the distance between the guide groove 111 and an end surface of the driving column 110 changes by one cycle, and the depth of the guide groove 111 changes by two cycles.

[0074] The wind guide assembly 200 swings for one cycle, and the depth of the driving column 110 extending into the guide groove 111 changes for two cycles. With such a configuration, the matching effect between the driving column 110 and the guide groove 111 can be further improved.

[0075] Optionally, the length of the driving rod 120 may be changed, and the length of the driving rod 120 becomes shorter when both ends of the driving rod 120 are subjected to a squeezing force.

[0076] In this way, the end of the driving rod 120 that extends into the guide groove 111 can abut against the bottom of the guide groove 111 during the swing cycle of the air guide assembly 200. This arrangement is conducive to the matching of the driving column 110 with the guide groove 111, and reduces the risk of the driving column 110 falling out of the guide groove 111.

[0077] Optionally, the air outlet device further includes a driving motor 240 , and an output shaft of the driving motor 240 penetrates into the driving column 110 .

[0078] The driving motor 240 is coaxially arranged and directly connected to the driving column 110. Such an arrangement can reduce the volume of the air outlet device, which is conducive to assembling the air outlet device to the refrigerator.

[0079] Combination Figure 1-5 As shown, an embodiment of the present disclosure provides a refrigerator, which includes an inner tank 10 and the above-mentioned air outlet device, wherein the inner tank 10 is provided with an air outlet 11; and an air guide component 200 of the air outlet device is arranged at the air outlet 11 of the inner tank 10.

[0080] The inner tank 10 of the refrigerator defines a refrigerated space. The inner tank 10 is provided with an air outlet 11 and an air return port. Cold air after heat exchange with the evaporator enters the refrigerated space from the air outlet 11 and leaves the refrigerated space from the air return port after heat exchange with the refrigerated objects in the refrigerated space.

[0081] The air outlet device is arranged at the air outlet 11 of the inner container 10, and the cold air can flow evenly to various positions of the refrigerated space through the swing of the air guide component 200.

[0082] When the air outlet device provided by the embodiment of the present disclosure is used, when the driving column 110 rotates continuously in one direction, the driving rod 120 reciprocating along the axial direction of the driving column 110 drives the air outlet assembly to swing back and forth. In this way, the air guide assembly 200 is driven in both directions by a unidirectional rotating motor, which simplifies the structure of the air outlet device and reduces the cost of the refrigerator air outlet device.

[0083] Optionally, the inner tank 10 protrudes outward to form a receiving groove 12, and the driving column 110 of the air outlet device is arranged in the receiving groove 12; the air outlet device also includes a driving motor 240, the driving motor 240 is arranged in the receiving groove 12, and the output shaft passes through the driving column 110.

[0084] The inner container 10 protrudes outward, thereby forming a receiving groove 12 in the refrigerator space. The sliding column and the driving motor 240 are arranged in the receiving groove 12, which can reduce the space occupied by the air outlet device.

[0085] Optionally, the inner liner 10 includes a back plate, the air outlet 11 is opened on the back plate of the inner liner 10 , and the accommodating groove 12 is constructed on the back plate of the inner liner 10 .

[0086] With such a configuration, on the one hand, the refrigerated objects placed in the refrigerated space are not likely to block the air outlet 11; on the other hand, the cold air is blown to the refrigerated space through the back plate, which is conducive to uniform cooling of the refrigerated space.

[0087] Optionally, the refrigerator further includes a temperature sensor and a control unit, wherein the temperature sensor is used to obtain the temperature of the refrigerated space, and the control unit is configured to control the air outlet angle of the air outlet device according to the temperature of the refrigerated space.

[0088] By adopting such a setting, the temperature uniformity of the refrigerated space can be further improved.

[0089] Optionally, the refrigerator includes a plurality of temperature sensors, and the plurality of temperature sensors are used to obtain the temperatures at different positions of the refrigeration space.

[0090] When a refrigerator is provided with multiple temperature sensors, the air outlet angle of the air outlet device is more targeted, and temperature management of different positions of the refrigerator can be achieved.

[0091] Optionally, the inner container is configured with a temperature detection groove, and the temperature sensor is arranged in the temperature detection groove.

[0092] This can prevent the temperature sensor from being damaged due to collision when taking or placing refrigerated objects.

[0093] Optionally, the control unit is further configured to control the air outlet device to swing and supply air when the temperature of the refrigerated space is lower than a preset temperature.

[0094] The temperature of the refrigerated space can be the temperature detected by a temperature sensor or the average temperature of multiple temperature sensors. When the temperature of the refrigerated space is lower than the temperature threshold, it is considered that the temperature of the refrigerated space needs to be quickly and evenly reduced. At this time, the air outlet device swings to supply air, which can quickly and evenly reduce the temperature of the refrigerated space to the temperature threshold and below the temperature threshold. With such a setting, the cooling speed and cooling uniformity of the refrigerator can be improved.

[0095] The above description and the accompanying drawings sufficiently illustrate the embodiments of the present disclosure to enable those skilled in the art to practice them.

Unless explicitly required, individual components and functions are optional, and the order of operations may vary.

The embodiments of the present disclosure are not limited to the structures described above and shown in the accompanying drawings, and various modifications and changes may be made without departing from the scope thereof. The scope of the present disclosure is limited only by the appended claims.
