DETAILED DESCRIPTION

[0025] ​With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments of the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative work fall within the scope of the present application.

[0026] In addition, the terms "first", "second" are only used for description purpose, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features, so that the features with "first" and "second" can explicitly or implicitly include one or more features, and in the description of the present application, the meaning of "multiple" is two or more than two, unless otherwise explicitly and specifically limited.

[0027] The embodiments of the present application provide a door seal assembly of a refrigerator, for example, refer to Figures 1-2 , Figure 1 The structural schematic diagram of the door seal assembly provided by the embodiments of the present application is shown in Figure 2 The cross-sectional view of the door seal assembly shown in Figure 1 The refrigerator includes a storage compartment and a door body cooperating with the storage compartment to open and close. The door seal assembly 100 includes a door seal strip 110 and a gas charging and discharging module 120.

[0028] The door seal strip 110 is arranged on the door body of the refrigerator, and a plurality of air bags 111 are arranged inside the door seal strip 110. The gas charging and discharging module 120 is connected with each air bag 111 and is used for charging or discharging each air bag 111. The gas charging and discharging module 120 is configured to adjust the air pressure of a target air bag 111 in the plurality of air bags 111 according to the temperature information of the storage compartment.

[0029] For example, the door seal strip 110 can be embedded in the mounting groove of the edge of the door body. The door seal strip 110 is integrally formed, for example, and the air bags 111 are formed inside. The door seal strip 110 can be made of elastic sealing material such as rubber, silicone, etc. The plurality of air bags 111 are independent of each other, and the internal cavities of the air bags 111 can change in volume and shape by gas charging and discharging. When the door body is closed, the air bags 111 with a certain air pressure are in contact with the cabinet and are compressed to form a seal.

[0030] The gas charging and discharging module 120 is connected with each air bag 111 through a pipeline, for example, to form a fluid communication system. The gas charging and discharging module 120 performs the operation of charging or discharging the specified air bag 111 based on the received gas charging and discharging instruction, so as to adjust the air pressure inside.

[0031] The temperature information can be monitored by a plurality of temperature sensors arranged in the storage compartment, for example, arranged in different areas of the storage compartment respectively to monitor the temperature changes of the different areas. It can be understood that the temperature condition in the storage compartment is the final manifestation of the sealing effect, which can reflect where the weak sealing point may exist. The refrigerator can determine the area with weak sealing in the storage compartment by analyzing the temperature information, and then determine the target air bag 111 that needs to be adjusted in air pressure, and control the air charging and discharging module 120 to accurately adjust the air pressure of the target air bag 111 through the air charging and discharging instruction.

[0032] The door seal assembly 100 of the refrigerator provided by the embodiments of the present application can intelligently determine the area with weak sealing condition by monitoring the temperature of the storage compartment, and can strengthen the sealing by accurately adjusting the air pressure of the air bag 111 corresponding to the position, so as to realize the conversion of the door seal from a static sealing element to a dynamic intelligent sealing system that can be accurately controlled in different areas. The sealing effect and service life can be effectively improved, and the energy saving, freshness preservation, reliability and intelligence of the refrigerator are comprehensively and significantly improved.

[0033] In a preferred embodiment, a plurality of air bags 111 are sequentially and spacedly arranged along the circumference of the door seal strip 110. For example, air bags 111 are arranged in the front, rear, left and right directions of the length direction of the door seal strip 110 respectively.

[0034] For example, please refer to Figure 3 , Figure 3 The structure diagram of the air charging and discharging module provided by the embodiments of the present application is connected with the air bag. The air charging and discharging module 120 includes an air pump 121, an electromagnetic valve 122, a control unit 123 and an air pressure detection unit 124.

[0035] The air pump 121 is connected with each air bag 111 to form an air conveying channel 125, which is used to charge or discharge the corresponding air bag 111 through the air conveying channel 125; the electromagnetic valve 122 is arranged on the air conveying channel 125, which is used to open or close the air conveying channel 125; the control unit 123 is connected with the electromagnetic valve 122 and the air pump 121, which is used to control the working state of the air pump 121 and the electromagnetic valve 122 in response to the air charging and discharging instruction, so as to realize the air pressure adjustment of the target air bag 111; wherein the air charging and discharging instruction is generated according to the temperature information of the storage compartment.

[0036] The air pump 121 is, for example, a micro air pump 121. The air pump 121 serves as an air source, the air inlet thereof can be communicated with the outside atmosphere, and the air outlet is connected with a plurality of branch air conveying channels through a main air conveying channel. Each branch air conveying channel is connected with one air bag 111, so as to form an independent air conveying channel 125 with each air bag 111. The air pump 121 can work in both forward and reverse directions. When working in the forward direction, air is pumped into the air bag 111, and when working in the reverse direction, air in the air bag 111 can be pumped out.

[0037] The solenoid valve 122 can be a multi-way solenoid valve 122, such as a four-way solenoid valve 122. The air inlet of the solenoid valve 122 is connected to the air outlet of the air pump 121, for example. Multiple air outlets are connected to multiple air pumps 121 one-to-one through branch air supply pipes, used to control the opening or closing of each air supply channel 125. When the solenoid valve 122 opens the branch air supply channel 125, its corresponding air bag 111 is connected to the air pump 121, and inflation and deflation operations can be performed; when the solenoid valve 122 closes the branch air supply channel 125, its corresponding air bag 111 is in a closed state, and the air pressure is maintained.

[0038] The inflation / deflation command is generated, for example, by the refrigerator's control module based on the temperature information of the storage compartment. The control unit 123 responds to the inflation / deflation command by parsing it to determine the target airbag 111 and the pressure adjustment action and parameters for that airbag 111. Subsequently, the control unit 123 controls the solenoid valve 122 connected to the target airbag 111 to open and controls the air pump 121 to operate in a corresponding mode and for a specified duration, thereby achieving precise pressure adjustment of the target airbag 111. After adjustment, the control unit 123 closes the corresponding solenoid valve 122 and stops the air pump 121. For example, based on the parsing of the inflation / deflation command, the control unit 123 determines to inflate the left airbag 111 for a first duration and the front airbag 111 for a second duration. Therefore, it controls the solenoid valve 122 to open the left airbag 111 and start the air pump 121 in forward rotation for a first duration, then closes the left airbag 111 and opens the front airbag 111, and controls the air pump 121 to continue in forward rotation for a second duration before closing it.

[0039] To form a closed-loop control and improve adjustment accuracy, in a more preferred embodiment, the inflation / deflation module 120 may further include a pressure detection unit 124. The pressure detection unit 124 may be installed on the air supply channel 125, for example, by installing a pressure sensor on each branch pipe, or installed inside the airbag 111, to detect the air pressure value of the target airbag 111 before, during, and after adjustment in real time or at regular intervals. The pressure detection unit 124 is connected to the control unit 123 and feeds back the detected air pressure value to the control unit 123. The control unit 123 can then more precisely control the operation of the air pump 121 based on the comparison between the feedback air pressure value and the target air pressure value, until the air pressure reaches the set value.

[0040] The refrigerator door seal assembly 100 provided in this application embodiment can intelligently determine areas with weak seals by monitoring the compartment temperature, and strengthen the seal by precisely adjusting the air pressure of the corresponding airbag 111. This transforms the door seal from a static sealing element into a dynamic, zone-controlled intelligent sealing system, which can effectively improve the sealing effect and service life, and brings a comprehensive and significant improvement to the refrigerator's energy saving, preservation, reliability and intelligence.

[0041] This application also provides a refrigerator, which can be a side-by-side refrigerator, a French door refrigerator, a French door refrigerator, or other types of refrigerators. The refrigerator includes at least one storage compartment, a door that cooperates with the storage compartment, a door seal assembly 100 as described in any of the above embodiments, and a control module. The control module is connected to an inflation / deflation module and is used to control the inflation / deflation module to adjust the air pressure of a target airbag among multiple airbags based on the temperature information of the storage compartment.

[0042] The door seal assembly 100 is installed on the door. When the door is closed, the door seal 110 contacts the refrigerator body, and the internal air bladder 111 deforms under air pressure, filling the gap between the door and the refrigerator body to achieve a seal. Through the coordinated work of the control module, the inflation / deflation module 120, and the air bladder 111, the refrigerator can intelligently and dynamically adjust the local sealing pressure of the door seal according to the actual operating conditions and temperature field distribution, thereby effectively suppressing cold air leakage and improving the overall energy efficiency and temperature uniformity of the storage compartment.

[0043] This application also provides a control method applied to the refrigerator described above. The control method can be executed by the refrigerator's controller. For an example, please refer to [link to example]. Figure 4 , Figure 4 A flowchart illustrating a refrigerator control method provided in an embodiment of this application. The control method includes the following steps S101-S103: Step S101: Obtain the temperature information of the storage room; For example, multiple temperature sensors installed in different areas of the storage room periodically collect temperature data from each area to obtain temperature information. For instance, temperature sensors are installed in the upper left, upper right, middle, lower left, and lower right areas of the storage room.

[0044] Step S102: Generate inflation / deflation commands for the inflation / deflation module based on the temperature information of the storage room; Understandably, the temperature inside the storage room is the ultimate indicator of the sealing effect, revealing potential weak points in the seal. By analyzing temperature information, the control module can identify areas with weak seals within the storage room, pinpoint the target airbag requiring pressure adjustment, and then control the inflation / deflation module to precisely adjust the pressure of that target airbag via inflation / deflation commands.

[0045] Step S103: Control the inflation / deflation module to adjust the air pressure of the target airbag among the multiple airbags.

[0046] The refrigerator control method provided in this application intelligently identifies areas with weak seals by monitoring the compartment temperature, and strengthens the seal by precisely adjusting the air pressure of the corresponding airbag. This transforms the door seal from a static seal into a dynamic, zone-controlled intelligent sealing system, effectively improving the sealing effect and service life, and bringing comprehensive and significant improvements to the refrigerator's energy saving, preservation, reliability, and intelligence.

[0047] Regarding how to determine the inflation / deflation command based on temperature information, this application proposes the following embodiment: generating the inflation / deflation command for the inflation / deflation module based on the temperature information of the storage compartment may include: Determine the rate of temperature recovery in each area of ​​the storage room based on temperature information; The target adjustment zone for each region is determined based on the rate of temperature recovery. The target airbag is determined based on the target adjustment area, and an inflation / deflation command is generated for the target airbag.

[0048] During the refrigerator compressor's shutdown period, the temperature inside the storage compartment gradually rises due to cold energy loss. By analyzing the temperature changes in each area over a specific time period, such as from the start of the previous shutdown to the current moment, the rate of temperature recovery for each area can be calculated. The faster the rate of recovery, the worse the insulation or sealing performance of that area may be, and the more severe the cold energy loss.

[0049] Optionally, determining the target adjustment region in each of the regions based on the temperature recovery rate includes: Compare the temperature recovery rate of each region with the corresponding target recovery rate; The region where the rate of temperature recovery exceeds the target rate of temperature recovery is defined as the target adjustment region.

[0050] As a reference value, the target temperature recovery rate can be a preset rate representing the temperature recovery rate under normal sealing conditions, or it can be the average temperature recovery rate during historical operating data of the region, such as multiple shutdowns. By comparing the magnitudes, the regions with temperature recovery rates greater than the reference value can be identified as the target adjustment regions requiring enhanced sealing.

[0051] Optionally, determining the corresponding target airbag based on the target adjustment area includes: determining the target airbag corresponding to the target adjustment area from multiple airbags based on a preset mapping relationship.

[0052] The refrigerator's control system can pre-store a mapping table that defines the correspondence between each area of ​​the storage compartment and one or more specific airbags on the door seal. For example, the upper left area may correspond to several airbags on the top left side of the door seal. Based on this pre-defined mapping, the target airbag corresponding to the target adjustment area can be found and determined from among multiple airbags. When generating an inflation / deflation command, the command content may include: the identifier of the target airbag, the target air pressure value, and the adjustment action required to achieve the target air pressure, such as inflation / deflation and its intensity / time.

[0053] In some other embodiments, determining the corresponding target airbag based on the target adjustment area and generating an inflation / deflation command for the target airbag includes: determining the corresponding core airbag based on the target adjustment area, and determining a first pressure adjustment value for the core airbag based on the temperature recovery rate of the target adjustment area; determining the peripheral airbags adjacent to the core airbag based on the position of the core airbag, and defining the peripheral airbags of the core airbag as target airbags; determining a second pressure adjustment value for each peripheral airbag based on the core airbag as the adjustment center and according to a preset attenuation function, wherein the absolute value of the second pressure adjustment value is less than the absolute value of the first pressure adjustment value; and generating an inflation / deflation command based on the first pressure adjustment value and the second pressure adjustment value.

[0054] In practical applications, the refrigerator's control module sends the generated inflation / deflation command to the control unit of the inflation / deflation module. The control unit parses the command and opens the solenoid valve connected to the target airbag, controlling the air pump to operate in the corresponding mode. Optionally, it can combine feedback from the air pressure detection unit for precise control until the air pressure in the target airbag is adjusted to the value required by the command. By appropriately increasing the air pressure in the target airbag, the contact pressure between the door seal and the cabinet in that area can be enhanced, thereby improving the sealing effect of the corresponding area and slowing down its temperature rise rate.

[0055] For example, please refer to Figure 5 , Figure 5 Another flowchart of the control method provided in this application embodiment. The control method includes the following steps S201-S20. Step S201: Monitor the rate of temperature recovery in each area of ​​the storage room; Step S202: Determine whether the temperature recovery rate of each region is less than or equal to the target recovery rate; If the temperature recovery rate in each region is less than or equal to the target recovery rate, return to step S201; otherwise, proceed to step S203.

[0056] Step S203: Determine the region where the temperature recovery rate is greater than the target recovery rate as the target adjustment region; Step S204: Determine the target airbag and the corresponding air pressure adjustment value based on the target adjustment area and the temperature rise rate of the target adjustment area, so as to generate an inflation / deflation command for the inflation / deflation module. Step S205: Control the inflation / deflation module to adjust the air pressure of the target airbag; Step S206: Determine whether the temperature recovery rate of the target adjustment area in the next cycle has returned to normal; If the temperature recovery rate of the target adjustment area returns to normal, proceed to step S207 below; otherwise, proceed to step S208 below.

[0057] Step S207: Confirm successful adjustment and maintain the current pressure settings for multiple airbags; Step S208: Increment the counter for the number of control failures; Step S209: Determine whether the number of failures exceeds the preset number; If the number of failures exceeds the preset number, proceed to step S210; otherwise, return to step S204.

[0058] Step S210: Record the fault and send a fault prompt message to the user.

[0059] The notification can be delivered via sound, light, display screen, mobile app, or voice. For example, the refrigerator can beep and its indicator light can flash to prompt the user to request maintenance. Alternatively, a fault notification message can be pushed to the user's mobile app to remind them to have the refrigerator checked.

[0060] The refrigerator control method provided in this application intelligently identifies areas with weak seals by monitoring the compartment temperature, and strengthens the seal by precisely adjusting the air pressure of the corresponding airbag. This transforms the door seal from a static seal into a dynamic, zone-controlled intelligent sealing system, effectively improving the sealing effect and service life, and bringing comprehensive and significant improvements to the refrigerator's energy saving, preservation, reliability, and intelligence.

The control device 300 includes an acquisition module 310, an analysis module 320, and an adjustment module 330.

[0062] The acquisition module 310 is used to acquire the temperature information of the storage room; the analysis module 320 is used to generate an inflation / deflation command for the inflation / deflation module based on the temperature information of the storage room; and the adjustment module 330 is used to control the inflation / deflation module to adjust the air pressure of the target airbag among the multiple airbags.
