However, the door body of the refrigerator is prone to door deviation.

[0003] The related technology discloses a method for preventing deformation of a refrigerator door body, including: adding a reinforcing iron inside the door body to prevent the door body from deforming, and adding a gasket inside the door body to prevent door deviation.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related technology:

[0005] The change in door deviation and the deformation amount of the door body are inconsistent due to the changes in the environmental temperature and the internal temperature, and it is impossible to accurately adjust the change in door deviation and the deformation amount, which will still cause lateral deviation of the door body and cold leakage and frosting after deformation, resulting in poor user experience.

[0052] As shown in combination with Figure 1 the embodiments of the present disclosure provide a freezer. A first inclination sensor 11 for detecting a first inclination angle of the door body 1, a second inclination sensor 12 for detecting a second inclination angle of the door body 1, a first electromagnetic coil 21 for adjusting the door locking force of the first side of the door body 1, a second electromagnetic coil 22 for adjusting the door locking force of the second side of the door body 1, and a third electromagnetic coil 23 for adjusting the door locking force in the middle of the door body 1 are provided on the door body 1 of the freezer. The first inclination angle is the inclination angle of the first part of the door body 1 relative to the horizontal position, and the second inclination angle is the inclination angle of the second part of the door body 1 relative to the horizontal position. The direction of the first part is opposite to the direction of the second part.

[0053] Using the refrigerator provided by the embodiments of the present disclosure, first, second, and third electromagnetic coils are arranged on the door body of the refrigerator, and the inclination angle of the first part of the door body relative to the horizontal position is detected as the first inclination angle, and the inclination angle of the second part relative to the horizontal position is detected as the second inclination angle. This is beneficial for better detecting the first inclination angle and the second inclination angle, thereby providing a structural basis for adjusting the door locking forces on the first side, the second side, and the middle according to the first inclination angle and the second inclination angle so that the first inclination angle and the second inclination angle meet the conditions of no side deviation and no deformation of the door body. It is beneficial for accurately adjusting the amount of door deviation change and deformation amount, avoiding cold leakage and frosting after the door body is side-deviated and deformed, and improving the user experience.

[0054] It should be noted that the first part can be the left part, the second part can be the right part, the first inclination angle can be the left inclination angle, and the second part can be the right inclination angle.

[0055] Optionally, the first electromagnetic coil 21 is arranged on the first side of the connection surface between the cabinet 2 and the door closing seal of the door body 1, and is used to generate the door locking force on the first side. The second electromagnetic coil 22 is arranged on the second side of the connection surface between the cabinet 2 and the door closing seal of the door body 1, and is used to generate the door locking force on the second side. The third electromagnetic coil 23 is arranged in the middle of the connection surface between the cabinet 2 and the door closing seal of the door body 1, and is used to generate the door locking force in the middle. Among them, the first side and the second side are opposite to each other.

[0056] In this way, it is beneficial to provide a structural basis for adjusting the door locking forces on the first side, the second side, and the middle according to the first inclination angle and the second inclination angle so that the first inclination angle and the second inclination angle meet the conditions of no side deviation and no deformation of the door body 1.

[0057] Optionally, the refrigerator further includes: a first side magnetic lock 13, a second side magnetic lock 14, and a middle magnetic lock 15. The first side magnetic lock 13 is arranged on the first side of the door body 1 and corresponds to the position of the first electromagnetic coil 21, and is used to generate an attractive force or a repulsive force on the first electromagnetic coil 21. The second side magnetic lock 14 is arranged on the second side of the door body 1 and corresponds to the position of the second electromagnetic coil 22, and is used to generate an attractive force or a repulsive force on the second electromagnetic coil 22. The middle magnetic lock 15 is arranged in the middle of the door body 1 and corresponds to the position of the third electromagnetic coil 23, and is used to generate an attractive force or a repulsive force on the third electromagnetic coil 23.

[0058] In this way, it is beneficial to better enable the first electromagnetic coil 21 to generate the door locking force and the door opening force on the first side, the second electromagnetic coil 22 to generate the door locking force and the door opening force on the second side, and the third electromagnetic coil 23 to generate the door locking force and the door opening force in the middle, thereby providing a structural basis for accurately adjusting the amount of door deviation change and deformation amount, avoiding cold leakage and frosting after the door body is side-deviated and deformed, and improving the user experience.

[0059] Optionally, the refrigerator further includes: a display device. The display device is configured to display an alarm prompt message indicating that the door seal, gasket or cabinet is uneven and needs to be replaced.

[0060] In this way, it is beneficial to prompt the user that the door seal, gasket or cabinet is uneven and needs to be replaced in time, avoiding cold leakage and frosting.

[0061] Combined with Figure 2 As shown, an embodiment of the present disclosure provides a method for preventing lateral deviation of a refrigerator door body, including:

[0062] S201, the refrigerator determines a first inclination angle and a second inclination angle.

[0063] S202, the refrigerator adjusts one or more of the first side door locking force, the second side door locking force, and the middle door locking force according to the first inclination angle and the second inclination angle, so that the first inclination angle and the second inclination angle meet the conditions of no lateral deviation and no deformation of the door body.

[0064] By using the method for preventing lateral deviation of a refrigerator door body provided by the embodiment of the present disclosure, first, second, and third electromagnetic coils are arranged on the door body of the refrigerator, and the inclination angle of the first part of the door body relative to the horizontal position is detected as the first inclination angle, and the inclination angle of the second part relative to the horizontal position is detected as the second inclination angle. According to the first inclination angle and the second inclination angle, the first side door locking force, the second side door locking force, and the middle door locking force are adjusted, so that the first inclination angle and the second inclination angle meet the conditions of no lateral deviation and no deformation of the door body. It is beneficial to accurately adjust the lateral deviation change amount and the deformation amount, avoid cold leakage and frosting after the door body is laterally deviated and deformed, and improve the user experience.

[0065] Optionally, the refrigerator adjusts one or more of the first side door locking force, the second side door locking force, and the middle door locking force according to the first inclination angle and the second inclination angle, so that the first inclination angle and the second inclination angle meet the conditions of no lateral deviation and no deformation of the door body, including: the refrigerator determines the lateral deviation situation and the deformation situation of the door body according to the first inclination angle and the second inclination angle. The refrigerator adjusts one or more of the first side door locking force, the second side door locking force, and the middle door locking force according to the lateral deviation situation and the deformation situation of the door body, so that the first inclination angle and the second inclination angle meet the conditions of no lateral deviation and no deformation of the door body.

[0066] In this way, according to the lateral deviation situation and the deformation situation of the door body determined by the first inclination angle and the second inclination angle, one or more of the first side door locking force, the second side door locking force, and the middle door locking force are adjusted, so that the first inclination angle and the second inclination angle meet the conditions of no lateral deviation and no deformation of the door body. It is beneficial to accurately adjust the lateral deviation change amount and the deformation amount, avoid cold leakage and frosting after the door body is laterally deviated and deformed, and improve the user experience.

[0067] Optionally, combined with Figure 3 、 4As shown, the refrigerator determines the lateral deviation and deformation of the door body based on the first inclination angle and the second inclination angle, including: when both the first inclination angle and the second inclination angle are zero, the refrigerator determines that the lateral deviation of the door body is no lateral deviation and the deformation of the door body is no deformation. Or, when the positive and negative of the first inclination angle and the second inclination angle are the same, or one is zero and the other is non-zero, the refrigerator determines that the deformation of the door body is no deformation, and determines the lateral deviation of the door body as lateral deviation in the first direction or lateral deviation in the second direction based on the first inclination angle and the second inclination angle. Or, when the positive and negative of the first inclination angle and the second inclination angle are opposite, the refrigerator determines that the lateral deviation of the door body is no lateral deviation, and determines the deformation of the door body as convex upward in the middle or concave downward in the middle based on the first inclination angle and the second inclination angle.

[0068] In this way, if both the first inclination angle and the second inclination angle are zero, it indicates that the door body is leveled. At this time, the lateral deviation of the door body is no lateral deviation and the deformation of the door body is no deformation. If the positive and negative of the first inclination angle and the second inclination angle are the same, or one is zero and the other is non-zero, it indicates that the first part and the second part of the door body are on the same plane at this time. At this time, lateral deviation occurs and no deformation occurs. Based on the first inclination angle and the second inclination angle, the lateral deviation of the door body can be determined as lateral deviation in the first direction or lateral deviation in the second direction. If the positive and negative of the first inclination angle and the second inclination angle are opposite, it indicates that the first part and the second part of the door body are not on the same plane at this time, which means that deformation occurs but no lateral deviation occurs at this time. In this way, it is beneficial to more accurately determine the lateral deviation and deformation of the door body, thereby facilitating the precise adjustment of the lateral deviation change amount and the deformation amount, avoiding cold leakage and frosting after the door body is laterally deviated and deformed, and improving the user experience.

[0069] Optionally, the refrigerator determines the lateral deviation of the door body as lateral deviation in the first direction or lateral deviation in the second direction based on the first inclination angle and the second inclination angle, including: when the first inclination angle is negative and the second inclination angle is non-positive, the refrigerator determines that the lateral deviation of the door body is lateral deviation in the first direction. Or, when the first inclination angle is non-negative and the second inclination angle is positive, the refrigerator determines that the lateral deviation of the door body is lateral deviation in the second direction.

[0070] In this way, if the first inclination angle is negative and the second inclination angle is non-positive, it indicates that the first part of the door body is laterally deviated in the first direction, the second part is in the horizontal plane or laterally deviated in the first direction, and the first part and the second part are still on the same plane. Therefore, it is determined as lateral deviation in the first direction and no deformation. If the first inclination angle is non-negative and the second inclination angle is positive, it indicates that the first part of the door body is in the horizontal plane or laterally deviated in the second direction, the second part is also laterally deviated in the second direction, and the first part and the second part are still on the same plane. Therefore, it is determined as lateral deviation in the second direction and no deformation. This is beneficial to more accurately determine the lateral deviation of the door body, thereby facilitating the precise adjustment of the lateral deviation change amount, avoiding cold leakage and frosting after the door body is laterally deviated, and improving the user experience.

[0071] Optionally, the refrigerator determines the deformation condition of the door body as convex in the middle or concave in the middle according to the first inclination angle and the second inclination angle, including: when the first inclination angle is negative and the second inclination angle is positive, the refrigerator determines that the deformation condition of the door body is convex in the middle. Or, when the first inclination angle is positive and the second inclination angle is negative, the refrigerator determines that the deformation condition of the door body is concave in the middle.

[0072] In this way, if the first inclination angle is positive and the second inclination angle is negative, the first part of the door body deflects to the first direction side, and the second part deflects to the second direction side. The first part and the second part are not in the same plane, so it is judged as convex in the middle. If the first inclination angle is negative and the second inclination angle is positive, the first part of the door body deflects to the second direction side, and the second part deflects to the first direction side. The first part and the second part are not in the same plane, so it is judged as concave in the middle. This is beneficial to accurately adjust the deformation amount of the door body, avoid cold leakage and frosting after the door body is deformed, and improve the user experience.

[0073] Optionally, the refrigerator adjusts one or more of the first side door locking force, the second side door locking force, and the middle door locking force according to the door body side deflection condition and the door body deformation condition, including: when the door body side deflection condition is no side deflection and the door body deformation condition is no deformation, the refrigerator keeps the first side door locking force, the second side door locking force, and the middle door locking force unchanged. Or, when the door body side deflection condition is side deflection in the first direction or side deflection in the second direction and the door body deformation condition is no deformation, the middle door locking force remains unchanged, and the first side door locking force or the second side door locking force is adjusted according to the door body side deflection condition. Or, when the door body side deflection condition is no side deflection and the door body deformation condition is convex in the middle or concave in the middle, the first side door locking force and the second side door locking force are kept unchanged and the middle door locking force is adjusted according to the door body deformation condition, or the middle door locking force is kept unchanged and the first side door locking force and the second side door locking force are adjusted according to the door body deformation condition.

[0074] In this way, if the door body has no side deflection and no deformation, it means that there will be no cold leakage and frosting. At this time, the first side door locking force, the second side door locking force, and the middle door locking force are kept unchanged. If the door body has side deflection and no deformation, it means that the first side door locking force or the second side door locking force is insufficient to meet the requirement of no side deflection, and the middle door locking force meets the requirement of no deformation. At this time, the first side door locking force or the second side door locking force is adjusted according to the condition, and the middle door locking force remains unchanged. If the door body has no side deflection and has deformation, it means that the first side door locking force and the second side door locking force are appropriate and the middle door locking force is too small, resulting in convexity in the middle. At this time, only the middle door locking force needs to be adjusted, or the middle door locking force is appropriate but the first side door locking force and the second side door locking force are too small, resulting in concavity in the middle. At this time, only the first side door locking force and the second side door locking force need to be adjusted. This is beneficial to accurately adjust the deformation amount of the door body, avoid cold leakage and frosting after the door body is deformed, and improve the user experience.

[0075] Optionally, the refrigerator adjusts the locking force of the first side or the locking force of the second side according to the lateral deviation of the door body, including: when the lateral deviation of the door body is in the first direction, the refrigerator increases the locking force of the second side, and the locking force of the first side remains unchanged. Or, when the lateral deviation of the door body is in the second direction, the refrigerator increases the locking force of the first side, and the locking force of the second side remains unchanged.

[0076] In this way, if the door body is laterally deviated in the first direction, it means that the locking force of the first side is appropriate, and the locking force of the second side is too small, which will cause the lateral deviation in the first direction. Without deformation, it means that the locking force in the middle is appropriate. At this time, only the locking force of the second side needs to be increased, and the locking force of the first side and the locking force in the middle remain unchanged. If the door body is laterally deviated in the second direction, it means that the locking force of the second side is appropriate, and the locking force of the first side is too small, which will cause the lateral deviation in the second direction. Without deformation, it means that the locking force in the middle is appropriate. At this time, only the locking force of the first side needs to be increased, and the locking force of the second side and the locking force in the middle remain unchanged. This is beneficial to more accurately determine the lateral deviation of the door body, thereby facilitating the precise adjustment of the door deviation change amount, avoiding cold leakage and frosting after the door body is laterally deviated, and improving the user experience.

[0077] Optionally, when the refrigerator increases the locking force of the second side, it includes: the refrigerator increases the locking force of the second side according to the locking force change value. Specifically, the value of the locking force change value can be 5N.

[0078] In this way, if the refrigerator has no deformation and is laterally deviated in the first direction, the locking force of the second side is gradually increased according to the locking force change value, avoiding overshoot caused by excessive adjustment at one time and avoiding other lateral deviations and deformations.

[0079] Optionally, when the refrigerator increases the locking force of the first side, it includes: the refrigerator increases the locking force of the first side according to the locking force change value.

[0080] In this way, if the refrigerator has no deformation and is laterally deviated in the second direction, the locking force of the first side is gradually increased according to the locking force change value, avoiding overshoot caused by excessive adjustment at one time and avoiding other lateral deviations and deformations.

[0081] Optionally, when the refrigerator adjusts the middle locking force while keeping the locking forces of the first side and the second side unchanged according to the deformation of the door body, it includes: when the deformation of the door body is convex upward in the middle, the refrigerator keeps the locking forces of the first side and the second side unchanged and increases the middle locking force.

[0082] In this way, if the middle of the door body is convex upward, the locking forces of the first side and the second side remain unchanged, and only the middle locking force needs to be increased to make the first part and the second part of the door body on the same plane. This is beneficial to precisely adjust the deformation amount of the door body, avoid cold leakage and frosting after the door body is deformed, and improve the user experience.

[0083] Optionally, the refrigerator increases the intermediate door locking force, including: the refrigerator increases the intermediate door locking force according to the change value of the door locking force.

[0084] In this way, if the middle of the door body bulges upward, the intermediate door locking force is gradually increased according to the change value of the door locking force, avoiding overshoot caused by excessive adjustment at one time and preventing other side deviations and deformations.

[0085] Optionally, the refrigerator keeps the intermediate door locking force unchanged and adjusts the first side door locking force and the second side door locking force according to the deformation condition of the door body, including: when the deformation condition of the door body is that the middle is concave, the refrigerator keeps the intermediate door locking force unchanged and increases the first side door locking force and the second side door locking force.

[0086] In this way, if the middle of the door body is concave, the intermediate door locking force remains unchanged, and the first side door locking force and the second side door locking force are increased, so that the first part and the second part of the door body are on the same plane. This is beneficial to accurately adjust the deformation amount of the door body, avoid cold leakage and frosting after the door body is deformed, and improve the user experience.

[0087] Optionally, the refrigerator increases the first side door locking force and the second side door locking force, including: the refrigerator increases the first side door locking force according to the change value of the door locking force, and increases the second side door locking force according to the change value of the door locking force.

[0088] In this way, if the middle of the door body is concave, the first side door locking force and the second side door locking force are gradually increased according to the change value of the door locking force, avoiding overshoot caused by excessive adjustment at one time and preventing other side deviations and deformations.

[0089] Optionally, the first inclination angle and the second inclination angle meet the conditions of no side deviation and no deformation of the door body, including: both the first inclination angle and the second inclination angle are zero, so that the side deviation condition of the door body is no side deviation and the deformation condition of the door body is no deformation.

[0090] In this way, adjust one or more of the first side door locking force, the second side door locking force, and the intermediate door locking force until both the first inclination angle and the second inclination angle are zero, so that the side deviation condition of the door body is no side deviation and the deformation condition of the door body is no deformation.

[0091] Optionally, after the refrigerator adjusts one or more of the first side door locking force, the second side door locking force, and the intermediate door locking force according to the first inclination angle and the second inclination angle, it further includes: the refrigerator sends an alarm prompt message that the door seal, gasket, or the box body is uneven and needs to be replaced according to the first side door locking force, the second side door locking force, the first inclination angle, and the second inclination angle.

[0092] In this way, after adjusting one or more of the first side door locking force, the second side door locking force, and the middle door locking force, according to the first side door locking force, the second side door locking force, the first inclination angle, and the second inclination angle, an alarm prompt message indicating that the door seal, gasket, or cabinet is uneven and needs to be replaced is sent to prompt the user to replace or repair the door seal, gasket, and cabinet in a timely manner.

[0093] Optionally, the refrigerator sends an alarm prompt message indicating that the door seal, gasket, or cabinet is uneven and needs to be replaced according to the first side door locking force, the second side door locking force, the first inclination angle, and the second inclination angle, including: when either the first side door locking force or the second side door locking force is greater than the door locking force threshold or both are greater than the door locking force threshold, the refrigerator determines whether the first inclination angle and the second inclination angle meet the conditions of no side deviation and no deformation of the door body. When the first inclination angle and the second inclination angle do not meet the conditions of no side deviation and no deformation of the door body, the refrigerator sends an alarm prompt message indicating that the door seal, gasket, or cabinet is uneven and needs to be replaced.

[0094] Specifically, the value of the door locking force threshold can be 70N.

[0095] In this way, if either the first side door locking force or the second side door locking force is greater than the door locking force threshold, and at this time the first inclination angle and the second inclination angle still do not meet the conditions of no side deviation and no deformation of the door body, it means that the door seal, gasket, or cabinet is uneven, and it is impossible to avoid cold leakage only by adjusting the first side door locking force or the second side door locking force. At this time, an alarm prompt message indicating that the door seal, gasket, or cabinet is uneven and needs to be replaced is sent. In this way, it is beneficial to avoid cold leakage and frosting after the door body is side-deviated and deformed, and improve the user experience.

[0096] Specifically, the refrigerator sends an alarm prompt message indicating that the door seal, gasket, or cabinet is uneven and needs to be replaced, including: the control display module of the refrigerator displays an alarm prompt message indicating that the door seal, gasket, or cabinet is uneven and needs to be replaced.

[0097] In this way, if either the first side door locking force or the second side door locking force is greater than the door locking force threshold, and at this time the first inclination angle and the second inclination angle still do not meet the conditions of no side deviation and no deformation of the door body, it means that the door seal, gasket, or cabinet is uneven, and it is impossible to avoid cold leakage only by adjusting the first side door locking force or the second side door locking force. At this time, the control display module displays an alarm prompt message indicating that the door seal, gasket, or cabinet is uneven and needs to be replaced. In this way, it is beneficial to avoid cold leakage and frosting after the door body is side-deviated and deformed, and improve the user experience.

[0098] Optionally, before the refrigerator determines the first inclination angle and the second inclination angle, it further includes: when the refrigerator is initially powered on and the refrigerator door is closed, the first side door locking force and the second side door locking force are both adjusted to the first initial door locking force, and the middle door locking force is the second initial door locking force. Among them, the first initial door locking force is less than the second initial door locking force.

[0099] Specifically, the value of the first initial door-locking force can be 10 N, and the value of the second initial door-locking force can be 30 N.

[0100] In this way, since the middle of the cold cabinet door bulges upward more frequently during the door-closing process, after power-on, the first side door-locking force and the second side door-locking force are set to the smaller first initial door-locking force, and the middle door-locking force is set to the larger second initial door-locking force, which is beneficial to reducing the occurrence of door deformation. Thus, it is beneficial to accurately adjust the door deviation change amount and the deformation amount, avoid cold leakage and frosting due to side deviation and deformation of the door body, and improve the user experience.

[0101] Combined with Figure 5 As shown, another method for preventing side deviation of the cold cabinet door body provided by the embodiments of the present disclosure includes:

[0102] S501, the cold cabinet determines the first inclination angle and the second inclination angle.

[0103] S502, the cold cabinet adjusts one or more of the first side door-locking force, the second side door-locking force, and the middle door-locking force according to the first inclination angle and the second inclination angle, so that the first inclination angle and the second inclination angle meet the conditions of no side deviation and no deformation of the door body.

[0104] S503, the cold cabinet sends an alarm prompt message that the door seal, gasket, or the cabinet is uneven and needs to be replaced according to the first side door-locking force, the second side door-locking force, the first inclination angle, and the second inclination angle.

[0105] By using the method for preventing side deviation of the cold cabinet door body provided by the embodiments of the present disclosure, first, second, and third electromagnetic coils are provided on the door body of the cold cabinet, and the inclination angle of the first part of the door body relative to the horizontal position is detected as the first inclination angle, and the inclination angle of the second part relative to the horizontal position is detected as the second inclination angle. According to the first inclination angle and the second inclination angle, the first side door-locking force, the second side door-locking force, and the middle door-locking force are adjusted so that the first inclination angle and the second inclination angle meet the conditions of no side deviation and no deformation of the door body. This is beneficial to accurately adjusting the door deviation change amount and the deformation amount, avoiding cold leakage and frosting due to side deviation and deformation of the door body, and improving the user experience. Then, according to the first side door-locking force, the second side door-locking force, the first inclination angle, and the second inclination angle, an alarm prompt message that the door seal, gasket, or the cabinet is uneven and needs to be replaced is sent to prompt the user to replace and repair the door seal, gasket, and cabinet in time. This better avoids cold leakage and frosting due to side deviation and deformation of the door body and improves the user experience.

[0106] Combined with Figure 6 As shown, another method for preventing side deviation of the cold cabinet door body provided by the embodiments of the present disclosure includes:

[0107] S601, when the cold cabinet is initially powered on and the refrigerator door is closed, the cold cabinet adjusts both the first side door-locking force and the second side door-locking force to the first initial door-locking force, and the middle door-locking force to the second initial door-locking force.

[0108] S602, the refrigerator determines a first inclination angle and a second inclination angle.

[0109] S603, the refrigerator adjusts one or more of the first side door-locking force, the second side door-locking force, and the middle door-locking force according to the first inclination angle and the second inclination angle, so that the first inclination angle and the second inclination angle meet the conditions of no side deviation and no deformation of the door body.

[0110] Wherein, the first initial door-locking force is less than the second initial door-locking force.

[0111] By using the method for preventing side deviation of the refrigerator door body provided by the embodiment of the present disclosure, first, second, and third electromagnetic coils are arranged on the door body of the refrigerator, and the inclination angle of the first part of the door body relative to the horizontal position is detected as the first inclination angle, and the inclination angle of the second part relative to the horizontal position is detected as the second inclination angle. Since the middle of the refrigerator door body bulges upward more frequently during the door-closing process, after power-on, the first side door-locking force and the second side door-locking force are set to a relatively small first initial door-locking force, and the middle door-locking force is set to a relatively large second initial door-locking force, which is beneficial to reducing the occurrence of door body deformation. According to the first inclination angle and the second inclination angle, the first side door-locking force, the second side door-locking force, and the middle door-locking force are adjusted so that the first inclination angle and the second inclination angle meet the conditions of no side deviation and no deformation of the door body. This is beneficial to accurately adjusting the side deviation change amount and the deformation amount, avoiding cold leakage and frosting after the door body is side-deviated and deformed, and improving the user experience.

[0112] Combined with Figure 7 As shown, the embodiment of the present disclosure provides a device 200 for preventing side deviation of a refrigerator door body, including a determination module 701 and a door-locking force adjustment module 702. The determination module 701 is configured to determine a first inclination angle and a second inclination angle.

[0113] Using the device 200 for preventing the side deviation of the cold cabinet door body provided by the embodiments of the present disclosure, first, second, and third electromagnetic coils are arranged on the door body of the cold cabinet, and the inclination angle of the first part of the door body relative to the horizontal position is detected as the first inclination angle, and the inclination angle of the second part relative to the horizontal position is detected as the second inclination angle. Since the middle of the cold cabinet door body bulges upward more frequently during the door closing process, after power-on, the door locking forces on the first side and the second side are set to a relatively small first initial door locking force, and the door locking force in the middle is set to a relatively large second initial door locking force, which is beneficial to reducing the occurrence of door body deformation. According to the first inclination angle and the second inclination angle, the door locking forces on the first side, the second side, and in the middle are adjusted so that the first inclination angle and the second inclination angle meet the conditions of no side deviation and no deformation of the door body. This is beneficial to accurately adjusting the amount of door deviation change and the amount of deformation, avoiding cold leakage and frosting after the door body is side-deviated and deformed, and improving the user experience.

Optionally, the device 300 may further include a communication interface 802 and a bus 803.
