[0042] 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.

[0043] The refrigerator with double doors has a larger lateral size and volume, which is more common in large-capacity refrigerators. The two doors of the double-door refrigerator are connected to the box body by hinges. If the position of the door is deviated, it may not only affect the sealing effect, but also affect the appearance of the refrigerator. In order to improve the installation accuracy of the refrigerator door body, an online detection system for the assembly flatness of the refrigerator door body is disclosed in the related art, which includes a controller, a conveying device connected to the controller and a distance measuring device. The conveying device is configured to convey the refrigerator along the product conveying line. The distance measuring device is configured to detect the distance from different areas of an end face of the door body of the refrigerator in the height direction to the distance measuring point of the distance measuring device under the control of the controller. It can automatically detect whether the refrigerator door body is assembled flat, realize the intelligent detection of the assembly flatness of the refrigerator door body, and improve the detection accuracy and detection efficiency. The problem of the related art is that the online detection system is integrated and arranged in the production line, and it is difficult to conveniently and accurately detect the alignment state of the refrigerator door after the refrigerator is off the line. For example, the position of the refrigerator door is offset during transportation or use, and the maintenance personnel or users can only adjust the position of the door by experience and vision.

[0044] In order to conveniently and accurately detect the alignment status of the refrigerator door, combined with Figure 1-7As shown, an embodiment of the present disclosure provides a door assembly for a refrigerator, wherein the refrigerator is configured with a storage space, and a take-in / put-out opening connected to the storage space is opened on the front side of the refrigerator; the door assembly comprises a first door body 110, a second door body 210, an imaging device 120 and an imaging auxiliary assembly 220, wherein the first door body 110 is hinged on one side of the take-in / put-out opening; the second door body 210 is hinged on the other side of the take-in / put-out opening, the second door body 210 and the second door body 210 are in a double-opening form, and the first side edge of the first door body 110 faces the first side edge of the second door body 210; the imaging device 120 is arranged on the first side edge of the first door body 110; the imaging auxiliary assembly 220 is arranged on the first side edge of the second door body 210, and the imaging device 120 faces the imaging auxiliary assembly 220.

[0045] The door assembly provided in the embodiment of the present disclosure is applied to a refrigerator with double doors, such as a cross-door refrigerator or a French four-door refrigerator.

[0046] The door assembly includes a first door 110 and a second door 210 in a split form. Exemplarily, the left side of the first door 110 is hinged to the left side of the access opening of the box 400, and the right side of the second door 210 is hinged to the right side of the access opening of the box 400. When the first door 110 and the second door 210 are closed, the right side of the first door 110 is opposite to the left side of the second door 210.

[0047] The imaging device 120 is disposed in one of the first door body 110 and the second door body 210, and the imaging auxiliary component 220 is disposed in the other of the first door body 110 and the second door body 210. The imaging auxiliary component 220 and the imaging device 120 are disposed relatively and used in conjunction to realize the detection of the alignment state of the refrigerator door.

[0048] Exemplarily, the imaging device 120 is disposed on the right side of the first door body 110, that is, the first side of the first door body 110; the imaging auxiliary component 220 is disposed on the left side of the second door body 210, that is, the first side of the second door body 210. The imaging auxiliary component 220 forms an image on the imaging device 120, and the alignment state of the refrigerator door is detected by comparing the actual imaging pattern with the preset imaging pattern.

[0049] Combination Figure 5-7As shown, when the door bodies of the refrigerator are in a non-aligned state, it is possible that the first door body 110 and the second door body 210 are uneven, or the first door body 110 or the second door body 210 is tilted left and right, or the distance between the first door body 110 and the second door body 210 is too large / too small. If the distance between the first door body 110 and the second door body 210 is greater than the preset distance, the actual imaging pattern of the imaging auxiliary component 220 is smaller than the preset imaging pattern; if the distance between the first door body 110 and the second door body 210 is less than the preset distance, the imaging pattern of the imaging auxiliary component 220 is larger than the preset imaging pattern; if the heights of the first door body 110 and the second door body 210 are inconsistent or not parallel, the position of the actual imaging pattern of the imaging auxiliary component 220 cannot overlap with the position of the preset imaging pattern.

[0050] By using the door body assembly provided in the embodiment of the present disclosure, the installation deviation of the refrigerator door can be magnified through the imaging auxiliary assembly 220 and the imaging device 120, so that the refrigerator can accurately detect the alignment state of the refrigerator door; the door body assembly is integrated with the imaging auxiliary assembly 220 and the imaging assembly, and the alignment state of the refrigerator door can be conveniently detected in the production, transportation and use environment of the refrigerator.

[0051] Optionally, the imaging auxiliary component includes an imaging patch 221, and the alignment state of the first door body and the second door body is determined according to the area imaged by the imaging patch 221 in the imaging device and the coordinates of the marking point.

[0052] Optionally, the door assembly further includes a control unit, which is configured to execute a method for detecting an alignment state of the refrigerator door.

[0053] As an embodiment, a method for detecting the alignment state of a refrigerator door includes: a control unit obtains an imaging area of ​​an imaging patch on an imaging device, calculates an overlapping area of ​​the imaging area and a preset imaging area, and determines the alignment state of the door according to the imaging area and the overlapping area.

[0054] When the first door and the second door of the refrigerator are in a misaligned state, the following situations are included: the distance between the first door and the second door is too large, the distance between the first door and the second door is too small, and the first door or the second door is skewed.

[0055] The imaging device and the imaging patch are respectively arranged on the first door body and the second door body, and the relative distance between the first door body and the second door body can be judged by the imaging pattern of the imaging patch on the imaging device.

[0056] Specifically, the door assembly is preset with a preset imaging area. If the distance between the first door body and the second door body is too large, the imaging area is smaller than the preset imaging area; if the distance between the first door body and the second door body is too small, the actual imaging is larger than the preset imaging area. By comparing the imaging area with the preset imaging area, it is possible to quickly and accurately determine whether the distance between the first door body and the second door body is too large or too small.

[0057] The imaging device and the imaging patch are respectively arranged on the first door body and the second door body, and the relative angle between the first door body and the second door body can be judged by the overlapping area of ​​the imaging pattern of the imaging patch on the imaging device and the preset imaging area.

[0058] Specifically, if the imaging pattern of the imaging patch coincides with the preset imaging area, the first door body and the second door body are at a preset relative angle; if the imaging pattern of the imaging patch does not coincide with the preset imaging area, the first door body and the second door body are not at the preset relative angle.

[0059] Optionally, the control unit obtains the imaging area of ​​the imaging patch on the imaging device, including:

[0060] The control unit obtains the number of pixels of the imaging patch imaged by the imaging device and determines the imaging area according to the number of pixels.

[0061] When the imaging patch is used in an imaging device for imaging, the more pixels the actual imaging pattern has, the larger the imaging area is, and the fewer pixels the actual imaging pattern has, the smaller the imaging area is. When the resolution of the imaging device is constant, the imaging area can be accurately determined based on the number of pixels.

[0062] Optionally, the control unit determines the alignment state of the door bodies according to the imaging area and the overlap area, including: the control unit determines whether the first door body and the second door body meet the distance condition according to the imaging area. If the first door body and the second door body meet the distance condition, the control unit determines whether the first door body and the second door body meet the angle condition according to the overlap area. If the first door body and the second door body meet the angle condition, the control unit determines that the door bodies are in an aligned state.

[0063] If the distance between the first door body and the second door body is small, the imaging area of ​​the actual imaging pattern is large. At this time, the actual imaging pattern may cover the preset imaging area, but the first door body and the second door body are actually in a misaligned state. Therefore, before judging whether the first door body and the second door body meet the angle condition, the refrigerator needs to judge whether the first door body and the second door body meet the distance condition. If the first door body and the second door body do not meet the distance condition, it is determined that the refrigerator door body is in a misaligned state. Only when the first door body and the second door body meet the distance condition, it is further judged whether the first door body and the second door body meet the distance condition. This step-by-step judgment method not only reduces the amount of calculation of the refrigerator, but also improves the accuracy of determining the alignment state of the refrigerator door body.

[0064] Optionally, the control unit determines whether the first door body and the second door body meet the distance condition according to the imaging area, including: the control unit calculates a first difference between the imaging area and a preset imaging area. If the first difference is greater than or equal to the first preset value, the control unit determines that the first door body and the second door body do not meet the distance condition. If the first difference is less than the preset value, the control unit determines that the first door body and the second door body meet the distance condition.

[0065] If the distance between the first door body and the second door body is within a certain range, it can be considered that the first door body and the second door body are at a preset distance. The preset distance between the first door body and the second door body is a range. Therefore, the first difference between the imaging area and the preset imaging area is taken as an absolute value. By comparing the first difference with the first preset value, it is determined whether the first door body and the second door body meet the distance condition. Specifically, if the distance between the first door body and the second door body is too large or too small, the first difference is larger than or equal to the first preset value; if the distance between the first door body and the second door body is within a preset distance interval, the first difference is less than the first preset value.

[0066] Optionally, the control unit determines whether the first door body and the second door body meet the distance condition according to the imaging area, and further includes: when the first difference is greater than or equal to the first preset value, the control unit compares the size of the imaging area and the preset imaging area. When the imaging area is greater than the preset imaging area, the control unit confirms that the relative distance between the first door body and the second door body is less than the preset distance. When the imaging area is less than the preset imaging area, the control unit confirms that the relative distance between the first door body and the second door body is greater than the preset distance.

[0067] When the first door body and the second door body do not meet the distance condition, the maintenance personnel or the user needs to adjust the first door body and the second door body. By comparing the size of the imaging area and the preset imaging area, it can be determined whether the distance between the first door body and the second door body is too large or too small. After the refrigerator determines whether the distance between the first door body and the second door body is too large or too small, it can provide auxiliary prompt information for the maintenance personnel or the user to adjust the refrigerator door body. This makes it convenient for the maintenance personnel or the user to adjust the refrigerator door body.

[0068] Optionally, when the first door body and the second door body meet the distance condition, the control unit determines whether the first door body and the second door body meet the angle condition according to the overlap area, including: the control unit calculates a second difference between the overlap area and a preset overlap area. When the second difference is greater than or equal to a second preset value, the control unit determines that the relative angle does not meet the angle condition; when the second difference is less than the second preset value, the control unit determines that the relative angle meets the angle condition.

[0069] The overlap area can only be less than or equal to the preset overlap area, so the second difference can be taken as an absolute value or not. When the first door body and the second door body meet the distance condition, the first door body and the second door body may still be misaligned or skewed. If the first door body and the second door body are misaligned, the overlap area is less than the preset overlap area; if the first door body and the second door body are skewed and not parallel, the overlap area is less than the preset overlap area.

[0070] If the second difference between the overlap area and the preset overlap area is smaller than the second preset value, the overlap area is smaller than the preset overlap area, and the first door body and the second door body are misaligned or skewed in height.

[0071] In this way, the relative angle between the first door body and the second door body can be accurately detected.

[0072] Optionally, when the first door body and the second door body meet the distance condition, the control unit determines whether the first door body and the second door body meet the angle condition based on the overlapping area, and also includes: the control unit prompts the adjustment direction of the first door body and / or the second door body based on the image of the preset imaging area.

[0073] Specifically, when the first door body and the second door body do not meet the angle condition, the overlap area is smaller than the preset overlap area, and at this time, there is a vacant part in the preset imaging area. The refrigerator prompts to adjust the first door body in a first direction, where the first direction is from the vacant part toward the center of the preset area; or, the refrigerator prompts to adjust the second door body in a second direction, where the second direction is from the center of the preset imaging area toward the vacant part.

[0074] Such a configuration can further facilitate maintenance personnel or be used to adjust the first door body and / or the second door body to an aligned state.

[0075] Optionally, as another embodiment, the method for detecting the alignment state of a refrigerator door executed by a control unit includes: the control unit obtains a first number of pixels of an imaging patch imaged on an imaging device; the control unit obtains a second number of pixels of the imaging patch within a preset imaging area; and the control unit determines the alignment state of the door based on the first number of pixels and the second number of pixels.

[0076] The door assembly is preset with a first preset number of pixels. If the distance between the first door and the second door is too large, the first number of pixels of the actual imaging pattern is less than the first preset number of pixels; if the distance between the first door and the second door is too small, the first number of pixels of the actual imaging pattern is greater than the first preset number of pixels. By comparing the first number of pixels with the first preset number of pixels, it is possible to quickly and accurately determine whether the distance between the first door and the second door is too large or too small.

[0077] The imaging device and the imaging patch are respectively arranged on the first door body and the second door body, and the relative angle between the first door body and the second door body can be judged by the second pixel number of the imaging pattern of the imaging patch on the imaging device in the preset imaging area.

[0078] Specifically, if the second pixel number of the actual imaging pattern of the imaging patch in the preset imaging area is less than the second preset pixel number, the first door body and the second door body are at a preset relative angle; if the second pixel number of the actual imaging pattern of the imaging patch in the preset imaging area is equal to the second preset pixel number, the first door body and the second door body are at a preset relative angle.

[0079] Optionally, the control unit obtains the first number of pixels of the imaging patch on the imaging device, including: the control unit uses an image segmentation algorithm to determine the target area of ​​the imaging patch on the imaging device. The control unit calculates the first number of pixels of the target area. The image segmentation algorithm performs segmentation based on the edge of the imaging pattern.

[0080] Image segmentation is the process of dividing an image into regions or segments that are similar or continuous in some property (such as color, texture, shape, etc.). The purpose of image segmentation algorithms is to simplify or change the representation of an image to make it easier to analyze and understand. Edge-based segmentation relies on detecting edges in an image, i.e. places where there is a sharp change in pixel intensity. Edge detection operators such as the Canny edge detector are often used for this purpose. This allows for a quick and accurate determination of the first pixel count.

[0081] Optionally, the imaging patch is provided with an identification point. As an embodiment, the method for detecting the alignment state of the refrigerator door body executed by the control unit includes: the control unit obtains the imaging area of ​​the imaging patch on the imaging device; the control unit obtains the actual coordinates of the identification point imaged by the imaging device; and the control unit determines the alignment state of the door body according to the imaging area and the actual coordinates.

[0082] Specifically, the door assembly is preset with a preset imaging area. If the distance between the first door body and the second door body is too large, the imaging area is smaller than the preset imaging area; if the distance between the first door body and the second door body is too small, the actual imaging is larger than the preset imaging area. By comparing the imaging area with the preset imaging area, it is possible to quickly and accurately determine whether the distance between the first door body and the second door body is too large or too small.

[0083] The imaging device and the imaging patch are respectively arranged on the first door body and the second door body. The actual coordinates of the identification point of the imaging patch on the imaging device are compared with the preset coordinates to determine whether the first door body and the second door body are at a preset relative angle.

[0084] Specifically, if the actual coordinates coincide with the preset coordinates, the first door body and the second door body are at a preset relative angle; if the actual coordinates do not coincide with the preset coordinates, the first door body and the second door body are not at the preset relative angle.

[0085] By using the door assembly provided in the embodiment of the present disclosure, it is possible to quickly and accurately determine whether the first door and the second door of the refrigerator are aligned, making it convenient for maintenance personnel or users to adjust the first door and the second door of the refrigerator to an aligned state.

[0086] Optionally, the control unit determines the alignment state of the door bodies according to the imaging area and the actual coordinates, including: the control unit determines whether the first door body and the second door body meet the distance condition according to the imaging area. If the first door body and the second door body meet the distance condition, the control unit determines whether the first door body and the second door body meet the angle condition according to the actual coordinates. If the first door body and the second door body meet the angle condition, the control unit determines that the door bodies are in an aligned state.

[0087] Before determining whether the first door body and the second door body meet the angle condition, the refrigerator needs to determine whether the first door body and the second door body meet the distance condition. If the first door body and the second door body do not meet the distance condition, it is determined that the refrigerator door body is in a misaligned state. Only when the first door body and the second door body meet the distance condition, it is further determined whether the first door body and the second door body meet the distance condition. This step-by-step judgment method not only reduces the amount of calculation of the refrigerator, but also improves the accuracy of determining the alignment state of the refrigerator door bodies.

[0088] Optionally, when the first door body and the second door body meet the distance condition, the control unit determines whether the first door body and the second door body meet the angle condition according to the actual coordinates, including: the control unit calculates a first distance between the actual coordinates and the preset coordinates. When the first distance is greater than or equal to a second preset value, the control unit determines that the relative angle does not meet the angle condition; when the first distance is less than the second preset value, the control unit determines that the relative angle meets the angle condition.

[0089] When the first door body and the second door body meet the distance condition, the first door body and the second door body may still be misaligned or skewed. If the first door body and the second door body are misaligned, the actual coordinates and the preset coordinates cannot coincide, and the first distance is greater than or equal to the second preset value. If the first door body and the second door body are skewed and not parallel, the actual coordinates and the preset coordinates cannot coincide, and the first distance is greater than or equal to the second preset value.

[0090] If the first distance is smaller than the second preset value, the actual coordinate is smaller than the preset actual coordinate, and at this time, the first door body and the second door body are misaligned or skewed in height.

[0091] In this way, the relative angle between the first door body and the second door body can be accurately detected.

[0092] Optionally, when the first door body and the second door body meet the distance condition, the control unit determines whether the first door body and the second door body meet the angle condition based on the actual coordinates, and also includes: the control unit prompts the adjustment direction of the first door body and / or the second door body based on the relative position of the actual coordinates and the preset distance.

[0093] Specifically, when the first door body and the second door body do not meet the angle condition, the distance between the actual coordinate and the preset coordinate is greater than or equal to the second preset value. The refrigerator prompts to adjust the first door body in a first direction, where the first direction is from the preset coordinate to the actual coordinate; or, the refrigerator prompts to adjust the second door body in a second direction, where the second direction is from the actual coordinate to the preset coordinate.

[0094] This can further facilitate maintenance personnel or be used to adjust the first door body and / or the second door body to an aligned state.

[0095] Optionally, the imaging auxiliary component includes a light emitting device, which forms a light spot on the imaging component when in operation, and the alignment state of the door body is determined according to the area and position of the light spot.

[0096] As an embodiment, the control unit executes a method for detecting the alignment state of a refrigerator door, and the method includes: the control unit divides the light spot into a first area and a second area according to a brightness threshold, and the brightness of the first area is greater than the brightness of the second area; the control unit determines the area of ​​the first area and the first coordinates of the center point of the first area; the control unit determines the alignment state of the door based on the area of ​​the first area and the first coordinates.

[0097] The imaging device and the light emitting device are respectively arranged on the first door body and the second door body, and the relative distance between the first door body and the second door body can be judged by the light spot of the light emitting device on the imaging device. The imaging device and the light emitting device are respectively arranged on the first door body and the second door body, and the relative angle between the first door body and the second door body can be judged by the concentricity of the light spot of the light emitting device on the imaging device and the preset imaging area.

[0098] Optionally, the control unit determines the area of ​​the first region and the first coordinates of the center point of the first region, including: the control unit calculates the number of pixels included in the first region. The control unit determines the area of ​​the first region according to the number of pixels. The control unit obtains the rows and columns of all pixels in the first region. The control unit calculates the average value of the rows and columns of all pixels in the first region and uses the average value as the first coordinate.

[0099] When the light-emitting device forms a light spot in the imaging device, the more pixels there are in the first area, the larger the imaging area is, and the fewer pixels there are in the actual imaging pattern, the smaller the imaging area is. When the resolution of the imaging device is constant, the imaging area can be accurately determined based on the number of pixels. The light spot is an irregular but closed pattern, and such a method can be used to simply and accurately obtain the first coordinates of the center point of the first area.

[0100] Optionally, the imaging auxiliary component includes a fluorescent device, and when the fluorescent device 222 is in operation, a plurality of fluorescent spots are formed in the imaging device, and the plurality of fluorescent spots include at least one identification fluorescent spot, and the alignment state of the first door body and the second door body is determined by detecting the number of fluorescent spots and the position of the identification fluorescent spot.

[0101] As an embodiment, the control unit executes a method for detecting the alignment state of a refrigerator door, the method comprising: the control unit obtains the number of fluorescent points in an imaging pattern of an imaging device; the control unit obtains the first coordinate of a marking point in the imaging pattern of the imaging device; the control unit determines the alignment state of the door based on the number of fluorescent points and the first coordinate.

[0102] The box is preset with a preset number. If the distance between the first door body and the second door body is too large, the number of fluorescent points is greater than the preset number; if the distance between the first door body and the second door body is too small, the actual imaging is less than the preset number. By comparing the number of fluorescent points with the preset number, it is possible to quickly and accurately determine whether the distance between the first door body and the second is too large or too small. If the identification point pattern coincides with the preset coordinates, the first door body and the second door body are at a preset relative angle. If the identification point pattern does not coincide with the preset coordinates, the first door body and the second door body are not at the preset relative angle.

[0103] Optionally, the control unit obtains the number of fluorescent dots in the imaging pattern of the imaging device, including:

[0104] The control unit pre-processes the imaging pattern of the plurality of fluorescent spots on the imaging device, performs binarization processing on the pre-processed imaging pattern, performs an erosion operation on the binarized imaging pattern to form a plurality of light spots, and performs connected component analysis and counting on the light spots in the imaging pattern.

[0105] The imaged pattern is preprocessed to improve the accuracy of the identification of the fluorescent dots. This may include steps such as denoising, contrast enhancement, and background correction. This helps to distinguish the fluorescent dots from the background. The preprocessing includes at least one of denoising, contrast enhancement, and background correction.

[0106] Binarization of the image is beneficial for subsequent spot recognition. Erosion of the binarized imaging pattern can shrink the boundary of the spot inward, thereby removing small noise points and improving the recognizability of the spot. In addition, the corrosion operation can help remove small bright spots caused by noise or other non-fluorescent signals. Connected component analysis is used to group pixels or regions in an image into connected regions. Connected component analysis can be used to identify independent spots, and each connected component represents a spot. By counting the spots after connected component analysis, the accurate number of fluorescent spots is obtained. In this way, the accuracy of obtaining the number of fluorescent spots can be improved.

[0107] Optionally, the door assembly further includes a speaker connected to the control unit and configured to provide voice prompts according to the alignment status of the refrigerator door.

[0108] Exemplarily, the voice prompt method is that when the refrigerator is in factory mode or debugging mode, if the refrigerator door is in an aligned state, a first prompt sound is emitted to prompt that the refrigerator door is aligned; if the refrigerator door is not aligned, a second prompt sound is emitted to prompt that the refrigerator door is not aligned.

[0109] In this way, the maintenance personnel or users can simply and effectively obtain the alignment status information of the refrigerator door.

[0110] Optionally, when the refrigerator door is in a misaligned state, the control unit is further configured to determine a position adjustment method for the refrigerator door, and the speaker plays a third prompt sound to prompt the position adjustment method for the refrigerator door.

[0111] The double-door door assembly needs to be connected to the box body 400 through multiple hinges. The refrigerator door has different adjustment methods when it is in different deflection states. The control unit determines the adjustment method according to the deflection state of the refrigerator door, and the speaker plays a third prompt sound to prompt the adjustment method, which is conducive to the maintenance personnel or users to correctly adjust the position of the refrigerator door.

[0113] The image of the imaging device 120 is transmitted to the display device 310 for display, so that the pattern of the projection device is easier to observe. In addition, the display device 310 can also be used to display the operating status of the refrigerator and the user's operation control. Displaying the image of the imaging device 120 through the display device 310 does not increase the cost of the refrigerator.

[0114] Optionally, the display device 310 is preset with a preset imaging area, and when the first door body 110 is aligned with the second door body 210, the imaging of the imaging auxiliary component 220 coincides with the preset imaging area.

[0115] The display device 310 is preset with a preset imaging area. When the refrigerator door is in the aligned state, the imaging of the imaging auxiliary component 220 on the imaging device 120 overlaps with the preset imaging area in a one-to-one ratio. This is conducive to the refrigerator to compare the actual imaging pattern with the preset imaging image, so as to determine the alignment state of the refrigerator door. In addition, the preset imaging area and the actual imaging pattern are displayed on the display device 310 of the refrigerator, which is conducive to the user's observation and intervention in the process of the refrigerator determining the alignment state of the door body.

[0116] Optionally, the imaging auxiliary component 220 is provided with an identification point, and the display device 310 is preset with a marking point corresponding to the identification point, and the identification point coincides with the marking point when the first door body 110 and the second door body 210 are aligned.

[0117] The display device 310 is preset with marking points, and the refrigerator can determine the degree of deflection of the refrigerator door by comparing the points and the identification points of the imaging auxiliary component 220, which is helpful for the refrigerator to better determine the alignment state of the first door body 110 and the second door body 210 and provide prompts for the adjustment direction of the first door body 110 and the second door body 210.

[0120] Optionally, the first side edge of the second door body 210 is recessed inward to form a second groove, and the imaging auxiliary component 220 is disposed in the second groove.

[0121] The imaging auxiliary component 220 is arranged in the second groove to protect the imaging auxiliary component 220, and reduce or prevent the imaging auxiliary component 220 from being scratched. In addition, the imaging auxiliary component 220 is arranged in the second groove to improve the contrast between the actual imaging pattern of the imaging auxiliary component 220 in the imaging device 120 and the ambient light, and can improve the recognizability of the actual imaging pattern of the imaging auxiliary component 220 in the imaging device 120.

[0122] Optionally, the door body assembly further includes a fill light, and the fill light is provided with a first groove or a second groove, and a light emitting direction of the fill light is toward the imaging auxiliary assembly 220 .

[0124] As another implementation, the fill light is disposed in the second groove and is located behind the imaging auxiliary assembly 220. In this case, the fill light provides backlight for the imaging auxiliary assembly 220, which can also improve the imaging effect of the imaging auxiliary assembly 220 in a weak light environment.

[0125] Optionally, the door assembly further includes a first cover plate, which is openably and closably disposed at the opening of the first groove.

[0126] The imaging auxiliary component 220 and the imaging device 120 are used less frequently.

[0127] Optionally, the door assembly further includes a second cover plate, which is openably and closably disposed at the opening of the second groove.

[0128] When there is no need to determine the alignment state of the door body, the second cover plate covers the second groove, which can protect the imaging auxiliary component 220 and improve the aesthetics of the second door body 210.

[0133] Optionally, the distance between the imaging device 120 and the imaging auxiliary assembly 220 and the upper end of the first door body 110 is greater than the distance between the imaging device 120 and the lower end of the door body.

[0134] In the case where the first lower hinge and the second lower hinge are not adjustable, the relative position between the lower portion of the first door body 110 and the lower portion of the second door body 210 is relatively fixed, and the upper portion of the first door body 110 and the upper portion of the second door body 210 are prone to deflection. The imaging device 120 and the imaging auxiliary component 220 are disposed near the upper portion of the first door body 110, which is conducive to magnifying the deflection between the first door body 110 and the second door body 210, thereby improving the accuracy of the refrigerator in determining the deflection state of the door bodies.

[0135] Optionally, the door assembly further includes a first level sensor, which is disposed on the first door 110 to detect a horizontal state of the first door 110 .

After such adjustment, not only can the first door body 110 and the second door body 210 be aligned, but also the first side of the first door body 110 and the second side of the second door body 210 can be in a vertical state. When the box body 400 is also in a vertical state, the relative position of the door body assembly and the box body 400 can also be in an aligned state. With such a setting form, the installation accuracy of the door body assembly compared to the refrigerator box body 400 can be improved.

[0137] Optionally, the door assembly further includes a second level sensor, which is disposed on the second door 210 to detect a horizontal state of the second door 210 .
