[0039] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0040] A refrigerator generally consists of a body and a door. The door is used to ensure that the cold air in the body does not leak. Therefore, whether the door is flat will affect the insulation effect of the refrigerator and further affect the user experience.

[0041] In the related art, after the refrigerator is installed, the manufacturer will generally check whether the door body is level to avoid misalignment of the door body. However, during the transportation of the refrigerator after it leaves the factory, the fasteners on the refrigerator may become loose due to collisions and other reasons. At the same time, since the weight of the door body is generally large, the door body may also be misaligned during transportation. When the user receives the refrigerator, the user can only rely on manual detection to detect whether the door body is level, and the detection results are inaccurate and inefficient. Therefore, if the door body of the refrigerator is misaligned during transportation, the user may not be able to obtain accurate detection results to adjust the door body, and may even be unable to detect some slight misalignments. This reduces the insulation effect and aesthetics of the refrigerator, thereby reducing the user experience.

[0042] The disclosed embodiments provide a door assembly and a refrigeration device. After the refrigeration device leaves the factory, the user can also use the detection device on the refrigeration device to detect whether the door is level. The detection result is more accurate and the user experience is better.

[0043] The embodiment of the present disclosure provides a door assembly, which is applied to a refrigeration device, and the refrigeration device includes a box body 10. The door assembly includes: a first door body 11, a second door body 12, a magnetic element 20 and a magnetic sensor 30. The first door body 11 is arranged on the box body 10; the second door body 12 is arranged on the box body 10 corresponding to the first door body 11; the magnetic element 20 is installed on the side of the first door body 11 facing the second door body 12; the magnetic sensor 30 is arranged at a position corresponding to the magnetic element 20 on the second door body 12; wherein the magnetic sensor 30 is used to obtain the attraction F of the magnetic element 20 at different positions of the first door body 11, and determine the door body offset position according to the attraction F.

[0044] Specifically, the first door body 11 and the second door body 12 are rotatably disposed on the box body 10, respectively, and the first door body 11 is located on the left or right side of the second door body 12. After the first door body 11 and the second door body 12 are installed on the box body 10, the first door body 11 and the second door body 12 can be fixed to the box body 10 with fasteners to prevent the first door body 11 and the second door body 12 from shaking and affecting the accuracy of the detection result. The wall surface of the first door body 11 facing the second door body 12 constitutes a first side wall surface, and the wall surface of the second door body 12 facing the first door body 11 constitutes a second side wall surface. The magnetic element 20 is installed on the first side wall surface of the first door body 11, and the magnetic sensor 30 is installed on the second side wall surface of the second door body 12, so that the magnetic sensor 30 can obtain the attraction F of the magnetic element 20 at the corresponding position.

[0045] After the magnetic sensor 30 obtains the attraction F of the magnetic element 20, the magnetic sensor 30 can determine whether the corresponding position of the door body is offset according to the attraction F. If the magnetic sensor 30 detects that the door body at the corresponding position is offset, it outputs an offset prompt and offset position information to the user to facilitate the user to adjust the position of the door body; if the magnetic sensor 30 does not detect that the door body at the corresponding position is offset, it outputs a door body level prompt to the user. The above-mentioned door body refers to the first door body 11 and / or the second door body 12. With this arrangement, after the refrigeration equipment leaves the factory, the user can also detect whether the door body is level through the detection device on the refrigeration equipment. The detection result is more accurate and the user experience is better.

[0046] In actual applications, the user may use the first door body 11 as a reference to determine whether the second door body 12 is offset, or may use the second door body 12 as a reference to determine whether the first door body 11 is offset.

[0047] If the first door body 11 is used as a reference, the door body offset includes: the second door body 12 is offset in a direction close to the first door body 11, or the second door body 12 is offset in a direction away from the first door body 11. If the second door body 12 is used as a reference, the door body offset includes: the first door body 11 is offset in a direction close to the second door body 12, or the first door body 11 is offset in a direction away from the second door body 12.

[0048] It can be understood that under the same conditions, the attraction force F is inversely proportional to the distance between the magnetic element 20 and the magnetic sensor 30. Therefore, the greater the attraction force F of the magnetic element 20 obtained by the magnetic sensor 30, the closer the distance between the first door body 11 and the second door body 12 at the corresponding position; the smaller the attraction force F of the magnetic element 20 obtained by the magnetic sensor 30, the farther the distance between the first door body 11 and the second door body 12 at the corresponding position.

[0049] In some embodiments, the door assembly includes a plurality of magnetic sensors 30 , and the plurality of magnetic sensors 30 are vertically arranged on the second door 12 , and the plurality of magnetic sensors 30 can respectively obtain the attraction force F of the magnetic element 20 at the corresponding position.

[0050] Specifically, a plurality of magnetic sensors 30 are evenly arranged vertically with the second door body 12, and magnetic elements 20 are provided at positions of the first door body 11 corresponding to the plurality of magnetic sensors 30, so that the plurality of magnetic sensors 30 can respectively obtain the attraction force F of the magnetic elements 20 at corresponding positions of the first door body 11. In this way, the offset direction, offset position and offset degree of different positions of the door body can be determined by the magnetic sensors 30 provided at different positions, so as to further improve the accuracy of the detection result.

[0051] In practical applications, the number of magnetic sensors 30 can be set according to the actual needs of users, for example, there can be two magnetic sensors 30 or three magnetic sensors 30. It is understandable that the greater the number of magnetic sensors 30, the more accurate the final detection result.

[0052] In some embodiments, the door assembly includes a plurality of magnetic elements 20 , and the plurality of magnetic elements 20 are disposed on the first door 11 corresponding to the plurality of magnetic sensors 30 .

[0053] Specifically, the number of magnetic elements 20 is the same as the number of magnetic sensors 30, and multiple magnetic elements 20 are respectively arranged on the first door body 11 corresponding to multiple magnetic sensors 30. In this way, the magnetic sensor 30 can detect the attraction F of the corresponding magnetic element 20, and then determine whether the door body is offset at that location. In this way, the size of a single magnetic element 20 can be reduced, making it convenient for users to install the magnetic element 20 on the first door body 11.

[0054] In some embodiments, the distance between two adjacent magnetic elements 20 is greater than or equal to a preset distance.

[0055] Specifically, when the door assembly is provided with a plurality of magnetic elements 20, the distance between two adjacent magnetic elements 20 is greater than or equal to the distance between the first door body 11 and the second door body 12. For example, the distance between two adjacent magnetic elements 20 is twice, three times, or four times the distance between the first door body 11 and the second door body 12. In this way, when the magnetic sensor 30 obtains the attraction force F of the corresponding magnetic element 20, the magnetic element 20 adjacent to the magnetic element 20 can be prevented from affecting the magnetic sensor 30.

[0056] In some embodiments, a magnetic element 20 is vertically disposed on the door body assembly; wherein the height of the upper end of the magnetic element 20 is higher than the height of the uppermost magnetic sensor 30, and the height of the lower end of the magnetic element 20 is lower than the height of the lowermost magnetic sensor 30.

[0057] Specifically, when the door body assembly is provided with a magnetic element 20, the length of the magnetic element 20 is greater than or equal to a preset length. When the door body assembly also includes a plurality of magnetic sensors 30, the height of the upper end of the magnetic element 20 is higher than the height of the uppermost magnetic sensor 30, and the height of the lower end of the magnetic element 20 is lower than the height of the lowermost magnetic sensor 30. In this way, the magnetic sensor 30 can determine whether a displacement occurs at different positions of the door body by obtaining the attraction F at different positions of the magnetic element 20. Such a configuration makes it more convenient to process the first door body 11 and the magnetic element 20.

[0058] In some embodiments, the door body assembly includes a first magnetic sensor 3130 and a second magnetic sensor 3230; wherein the first magnetic sensor 3130 is arranged at the upper half of the second door body 12, for obtaining the attraction F of the magnetic element 20 located in the upper half of the first door body 11; the second magnetic sensor 3230 is arranged at the lower half of the second door body 12, for obtaining the attraction F of the magnetic element 20 located in the lower half of the first door body 11.

[0059] Specifically, the first magnetic sensor 3130 is disposed at the upper half of the second door body 12, and is used to obtain the first attraction F1 of the magnetic element 20 disposed at the upper half of the first door body 11. The second magnetic sensor 3230 is disposed at the lower half of the second door body 12, and is used to obtain the second attraction F2 of the magnetic element 20 disposed at the lower half of the first door body 11. In this way, the first magnetic sensor 3130 can determine whether the upper half of the door body is offset according to the first attraction F1, and the second magnetic sensor 3230 can determine whether the lower half of the door body is offset according to the second attraction F2. Such a configuration makes it more convenient for users to adjust the position of the first door body 11 and / or the second door body 12.

[0060] Optionally, optionally, the first difference ΔF1 refers to the current difference between the first attraction F1 and the attraction threshold F0, and the second difference ΔF2 refers to the current difference between the second attraction F2 and the attraction threshold F0. If ΔF1>ΔF, and ΔF2≤ΔF, it means that the lower part of the door body is in a flush state and the upper part is in an offset state. If ΔF1≤ΔF, and ΔF2>ΔF, it means that the lower part of the door body is in an offset state and the upper part is in a flush state. If ΔF1>ΔF, and ΔF2>ΔF, it means that both the upper and lower parts of the door body are in an offset state. If ΔF1≤ΔF, and ΔF2≤ΔF, it means that both the upper and lower parts of the door body are in a flush state.

[0061] In practical applications, the first difference ΔF1 and the second difference ΔF2 can also be used to determine whether the door body is deformed. For example, if ΔF1>ΔF and ΔF2≤ΔF, it means that the upper part of the door body may be deformed; if ΔF1≤ΔF and ΔF2>ΔF, it means that the lower part of the door body may be deformed.

[0062] In some practical applications, the door assembly includes a first magnetic element 2120, a second magnetic element 2220, a first magnetic sensor 3130, and a second magnetic sensor 3230. The first magnetic sensor 3130 is disposed at the upper half of the second door body 12, the first magnetic element 2120 is disposed at the upper half of the first door body 11, and is disposed corresponding to the first magnetic sensor 3130. The second magnetic sensor 3230 is disposed at the lower half of the second door body 12, the second magnetic element 2220 is disposed at the lower half of the first door body 11, and is disposed corresponding to the second magnetic sensor 3230. The first magnetic sensor 3130 can obtain the first attraction force F1 of the first magnetic element 2120, and judge whether the upper half of the door body is offset according to the first attraction force F1. The second magnetic sensor 3230 can obtain the second attraction force F2 of the second magnetic element 2220, and judge whether the lower half of the door body is offset according to the second attraction force F2.

[0063] In some embodiments, the door body assembly also includes a third magnetic sensor 3330 ; wherein the third magnetic sensor 3330 is disposed in the middle of the second door body 12 , and is used to obtain the attraction F of the magnetic element 20 located in the middle of the first door body 11 .

[0064] Specifically, the third magnetic sensor 3330 is disposed between the first magnetic sensor 3130 and the second magnetic sensor 3230, and is used to obtain the third attraction F3 of the magnetic element 20 disposed in the middle of the first door body 11, and determine whether the middle of the door body is offset according to the third attraction F3.

[0065] Optionally, the deformation of the middle part of the door body can also be determined by the third attraction force F3. When ΔF1≤ΔF, ΔF2≤ΔF, and ΔF3≤ΔF, the door body is determined to be in a flush state; when ΔF1≤ΔF, ΔF2≤ΔF, and ΔF3>ΔF, the door body is determined to be in a deformed state. The third difference ΔF3 refers to the current difference between the third attraction force F3 and the attraction force threshold F0.

[0066] In some embodiments, the magnetic element 20 is detachably mounted on the first door body 11 ; the magnetic sensor 30 is detachably mounted on the second door body 12 .

[0067] Specifically, a snap-in groove is provided at a position corresponding to the first door body 11 and the magnetic element 20, and the magnetic element 20 can be snap-fitted into the snap-in groove to be installed on the first door body 11. Similarly, a snap-in groove is also provided at a position corresponding to the second door body 12 and the magnetic sensor 30, and the magnetic sensor 30 can be snap-fitted into the snap-in groove to be installed on the second door body 12.

[0068] In some embodiments, the door assembly further includes: a display device 40. The display device 40 is disposed on the first door body 11, the second door body 12 or the box body 10 and is electrically connected to the magnetic sensor 30; wherein, after the magnetic sensor 30 determines the offset position of the door body, the display device 40 can output corresponding prompt information.

[0069] Specifically, the display device 40 is fixedly mounted on the first door body 11, the second door body 12 or the box body 10. The magnetic sensor 30 can output prompt information to the user in the form of sound, light or text through the display device 40.

[0070] The embodiment of the present disclosure further provides a refrigeration device including: a box body 10 and the above-mentioned door body assembly.

[0071] Specifically, the door assembly is installed on the box body 10, and the first door body 11 is located on the left or right side of the second door body 12. After the refrigeration device using the door assembly provided by the present application leaves the factory, the user can also detect whether the door body is flush through the detection device on the refrigeration device, and the detection result is more accurate, and the user experience is better.
