The following description is provided to enable any person skilled in the art to make and use this application. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that this application can be made without using these specific details. In other instances, well-known structures and processes are not described in detail to avoid obscuring the description of this application with unnecessary detail. Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0044] This application provides a damper assembly applied to a refrigerator, which can be a single-door, double-door, side-by-side, French door, cross-door, or other type of refrigerator. For example, please refer to... Figure 1 , Figure 1This is a schematic diagram of the structure of the damper assembly provided in an embodiment of this application. The damper assembly 100 includes a damper 110, and the damper assembly 100 also includes a color detection device 120 and / or a conductivity detection device 130.

[0045] The damper 110 includes a body 111, and further includes a first coating 112 and / or a second coating 113. The first coating 112 is disposed on the first surface 1111 of the body 111 and is adapted to display a corresponding color according to the environmental parameters of the location. The second coating 113 is disposed on the second surface 1112 of the body 111 and is adapted to have a corresponding conductivity according to the environmental parameters of the location. The color detection device 120 is used to detect the color displayed by the first coating 112. The conductivity detection device 130 is adapted to be connected to the second coating 113 to detect the conductivity of the second coating 113.

[0046] There are three implementations of the structure of the damper 110: the first is that the damper 110 includes a body 111 and a first coating 112, but does not include a second coating 113, then the damper assembly 100 may include the damper 110 and a color detection device 120, but does not include a conductivity detection device 130; the second is that the damper 110 includes a body 111 and a second coating 113, but does not include a first coating 112, then the damper assembly 100 may include the damper 110 and a conductivity detection device 130, but does not include a color detection device 120; the third is that the damper 110 includes a body 111, a first coating 112 and a second coating 113, then the damper assembly 100 may include the damper 110, a color detection device 120 and a conductivity detection device 130.

[0047] It should be noted that the refrigerator 10 uses a supply and return air duct to supply and return air from the refrigeration chamber to the storage compartment. The damper 110 is located within this duct. By adjusting the opening of the damper 110, the amount of cold air entering the storage compartment can be controlled, thereby regulating the temperature of the storage compartment. After the refrigerator 10 has been running for a period of time, low-temperature air continuously flows through the duct. When the air temperature is too low or the humidity is too high, ice can easily form on the surface of the damper 110, affecting its normal opening and closing action. This may consequently affect the refrigeration of the storage compartment of the refrigerator 10, resulting in poor food storage performance.

[0048] Environmental parameters may include ambient temperature, humidity, and dielectric constant. When ice forms on the surface of the first coating 112, the environmental parameters of the first coating 112 surface will change, thereby changing the color of the first coating 112. Understandably, by detecting the color displayed by the first coating 112, it is possible to determine whether ice has formed on the surface of the first coating 112, and thus determine the icing status of the damper 110. Furthermore, when ice forms on the surface of the second coating 113, the environmental parameters of the second coating 113 surface will change, thereby changing the conductivity of the second coating 113. Understandably, by detecting the conductivity of the second coating 113, it is possible to determine whether ice has formed on the second coating 113, and thus determine the icing status of the damper 110.

[0049] Optionally, the first coating 112 includes a nano-silver coating. Nano-silver possesses unique optical properties, especially its surface plasmon resonance effect. When environmental parameters surrounding the nano-silver particles, such as temperature, humidity, and dielectric constant, change, the surface plasmon resonance effect causes a color change. Ice formation on the surface of the first coating 112 alters the environmental parameters surrounding the nano-silver in the coating, thereby causing a color change in the first coating 112. For example, when the surface of the first coating 112 is not iced, it appears silver-gray; when the surface of the first coating 112 is iced, it appears white. During production, a nano-silver coating can be applied to the first surface 1111 of the substrate 111 using a spraying technique, and the first coating 112 is formed after the nano-silver coating dries and cures. Preferably, when spraying the nano-silver, the spraying pressure is controlled at 0.5 MPa, the spraying time is 1 hour, the particle size of the nano-silver is controlled at 10 nm, and the concentration is controlled at 0.1 mg / mL. The color detection device 120 may be embedded in the first coating 112. Optionally, the color detection device 120 is a four-channel or eight-channel spectroradiometer with a measurement range of 400-700nm and a measurement accuracy of ±1nm.

[0050] Optionally, the second coating 113 includes a graphene nanocoating. Graphene exhibits thermoelectric effects; its conductivity changes when environmental parameters around the graphene, such as temperature and humidity, change. Icing on the surface of the second coating 113 alters the environmental parameters surrounding the graphene in the coating, thereby causing a change in the conductivity of the second coating 113. During production, a dip-coating technique can be used to coat the second surface 1112 of the substrate 111 with a graphene nanocoating. After the graphene nanocoating dries and cures, the second coating 113 is formed. Preferably, during the dip-coating of the graphene nanocoating, the dip-coating pressure is controlled at 0.2 MPa, and the dip-coating time is 2 hours. The thickness of the graphene is controlled at 0.3 nm, and the concentration is controlled at 0.01 mg / mL. The conductivity detection device 130 can be embedded in the second coating 113. Optionally, the conductivity detection device 130 is a four-probe conductivity sensor with a measurement range of 0.1-100 S / cm and a measurement accuracy of ±0.1 S / cm.

[0051] In some embodiments, the first surface 1111 is the windward side, and the second surface 1112 is the leeward side. For example, the refrigerator 10 includes an air duct 200, and a damper 110 is disposed within the air duct 200. When the damper 110 is closed, along the airflow direction of the air duct 200, the first coating 112, the body 111, and the second coating 113 are sequentially disposed. Thus, the first coating 112 is disposed on the windward side of the body 111, and the second coating 113 is disposed on the leeward side of the body 111. The color of the first coating 112 is detected by a color detection device 120 to determine the icing condition of the windward side of the damper 110, and the conductivity of the second coating 113 is detected by a conductivity detection device 130 to determine the icing condition of the leeward side of the damper 110. Therefore, the overall icing condition of the damper 110 can be determined by comprehensively considering the icing conditions of the windward and leeward sides of the damper 110.

[0052] The damper assembly 100 provided in this application embodiment has a first coating 112 and / or a second coating 113 added to the surface of the damper body 111. By monitoring the color displayed by the first coating 112 and / or the conductivity of the second coating 113, changes in environmental parameters occurring on the surface of the damper 110 can be understood in a timely manner, thereby determining the icing status of the damper 110. Thus, when an icing failure is determined in the damper 110, de-icing measures can be taken promptly to prevent abnormal opening and closing of the damper 110 from affecting the normal cooling of the refrigerator compartment 10.

[0053] This application also provides a refrigerator, which can be a single-door, double-door, side-by-side, French door, cross-door, or other type of refrigerator. For example, please refer to... Figures 2-3 , Figure 2 This is a schematic diagram of the structure of a refrigerator provided in an embodiment of this application.Figure 3 This is another structural schematic diagram of a refrigerator provided in an embodiment of this application. The refrigerator 10 includes the damper assembly 100 and the air duct 200 as described in any of the above embodiments. The damper assembly 100 is disposed in the air duct 200.

[0054] In some embodiments, the refrigerator 10 further includes a defrosting device 300 disposed on the air duct 200 and adapted to defrost the air damper 110 when it is iced up. Optionally, the defrosting device 300 includes a vibration device and / or a heater.

[0055] In some embodiments, the refrigerator 10 further includes an alarm device 400, which is adapted to defrost the damper 110 when it is iced up. Optionally, the alarm device 400 is an audible and visual alarm with an audible alarm frequency of 1 kHz and a visual alarm brightness of 100 cd.

[0056] The refrigerator 10 provided in this application embodiment has a first coating 112 and / or a second coating 113 added to the surface of the body 111 of the damper 110. By monitoring the color displayed by the first coating 112 and / or the conductivity of the second coating 113, changes in environmental parameters occurring on the surface of the damper 110 can be understood in a timely manner, thereby determining the icing status of the damper. In this way, when it is determined that the damper 110 has an icing fault, de-icing measures can be taken in a timely manner to prevent abnormal opening and closing of the damper 110 from affecting the normal cooling of the refrigerator 10's storage compartment.

[0057] This application also provides an icing detection method, which is applied to the damper assembly 100 in any of the above embodiments. The refrigerator 10 also includes, for example, a controller adapted to be connected to a color detection device 120 and a conductivity detection device 130, for executing the icing detection method. For example, please refer to... Figure 4 , Figure 4 A flowchart illustrating an icing detection method provided in this application embodiment. The icing detection method includes the following steps S101-S102:

[0058] Step S101: Obtain the color displayed by the first coating 112 and / or the conductivity of the second coating 113;

[0059] For example, the controller may acquire the color displayed by the first coating 112 and / or the conductivity of the second coating 113 at preset intervals for icing determination. In this way, icing of the damper 110 can be detected in a timely manner.

[0060] Step S102: Determine the icing state of the damper 110 based on its color and conductivity.

[0061] It should be noted that the icing detection method of this application includes three implementation methods; the first method is that the damper 110 includes a body 111 and a first coating 112, and the icing detection method includes obtaining the color currently displayed by the first coating 112 to determine the icing state of the damper 110 based on the color; the second method is that the damper 110 includes a body 111 and a second coating 113, and the icing detection method includes obtaining the conductivity of the second coating 113 to determine the icing state of the damper 110 based on the conductivity; the third method is that the damper 110 includes a body 111, a first coating 112 and a second coating 113, and the icing detection method includes obtaining the color currently displayed by the first coating 112 and the conductivity of the second coating 113; and determining the icing state of the damper 110 based on the color and conductivity.

[0062] Regarding how to determine the icing state of damper 110 based on color and conductivity, this application provides an implementation method. For example, in the icing detection method, determining the icing state of damper 110 based on color and / or conductivity includes:

[0063] Obtain the preset standard color and determine whether the color displayed by the current first coating layer 112 is consistent with the preset standard color;

[0064] And / or obtain a preset conductivity range, and determine whether the current conductivity of the second coating 113 exceeds the preset conductivity range;

[0065] If the color displayed by the first coating 112 is inconsistent with the preset standard color, and / or the conductivity of the second coating 113 exceeds the preset conductivity range, then it is determined that the damper 110 is icing.

[0066] The method of determining the icing state of the damper 110 based on color and / or conductivity includes three implementation methods: the first method is to determine the icing state of the damper 110 solely based on color; the second method is to determine the icing state of the damper 110 solely based on conductivity; and the third method is to determine the icing state of the damper 110 based on a combination of color and conductivity. When the implementation method determines the icing state of the damper 110 based on color, this step may include: obtaining a preset standard color and determining whether the color currently displayed by the first coating 112 is consistent with the preset standard color; if the color currently displayed by the first coating 112 is inconsistent with the preset standard color, then it is determined that the damper 110 is icing. When the implementation method determines the icing state of the damper 110 based on conductivity, this step may include: obtaining a preset conductivity range and determining whether the conductivity of the current second coating 113 exceeds the preset conductivity range; if the conductivity of the second coating 113 exceeds the preset conductivity range, then it is determined that the damper 110 is icing. When the implementation method determines the icing state of the damper 110 based on a combination of color and conductivity, this step may include: obtaining a preset standard color and a preset conductivity range, and determining whether the color displayed by the current first coating 112 is consistent with the preset standard color, and determining whether the conductivity of the current second coating 113 exceeds the preset conductivity range; if the color displayed by the current first coating is inconsistent with the preset standard color, and / or the conductivity of the second coating exceeds the preset conductivity range, then it is determined that the damper is icing.

[0067] In some other embodiments, when the implementation method is to determine the icing state of the damper 110 based on a combination of color and conductivity, this step may include: obtaining a preset standard color and a preset conductivity range, and determining whether the color displayed by the current first coating 112 is consistent with the preset standard color, and determining whether the conductivity of the current second coating 113 exceeds the preset conductivity range; if the color displayed by the current first coating is inconsistent with the preset standard color, and the conductivity of the second coating exceeds the preset conductivity range, then it is determined that the damper is icing.

[0068] It should be noted that when the surface of the first coating 112 displays a preset standard color, it indicates that the surface of the first coating 112 is not currently icy. The preset standard color can be set by the designer based on the actual parameters of the first coating 112 and other actual data of the refrigerator 10. The preset conductivity range is a range of conductivity values; when the conductivity of the second coating 113 is within the preset conductivity range, it indicates that the surface of the second coating 113 is not currently icy. The preset conductivity range can be set by the designer based on the actual parameters of the second coating 113 and other actual data of the refrigerator 10.

[0069] In some embodiments, the damper 110 includes a second coating 113, which is also adapted to radiate heat when energized; after determining that the damper 110 is icing, the icing detection method further includes: controlling the second coating 113 to be energized to de-ice the damper 110.

[0070] Understandably, in addition to detecting ice buildup, the second coating 113 can also be used for heating to defrost the damper 110. Thus, the refrigerator 10 does not require a separate heater to defrost the damper 110, saving materials, reducing costs, and improving the utilization of the refrigerator 10's internal space.

[0071] In one parallel embodiment, the damper 110 includes a second coating 113 adapted to radiate heat to the surroundings when energized; after determining that icing exists on the damper 110, the icing detection method further includes:

[0072] Obtain the temperature of damper 110;

[0073] If the temperature of damper 110 is lower than the preset temperature value, the second coating 113 is energized to de-ice damper 110.

[0074] It should be noted that if the temperature of the damper 110 is lower than the preset temperature value, it means that the current degree of icing on the damper 110 has reached the preset condition. The damper 110 needs to be de-iced immediately to prevent the damper 110 from being unable to open and close normally, which would affect the cooling effect and normal operation of the refrigerator 10.

[0075] Understandably, in addition to detecting ice buildup, the second coating 113 can also be used for heating to defrost the damper 110. Thus, the refrigerator 10 does not require a separate heater to defrost the damper 110, saving materials, reducing costs, and improving the utilization of the refrigerator 10's internal space.

[0076] In some other embodiments, a heater may be provided in the refrigerator 10. When the temperature of the damper 110 is detected to be lower than a preset temperature value, the heater is controlled to open to defrost the damper 110. The heater may have a power of 1kW and a heating temperature of 10°C.

[0077] In some embodiments, after determining that the damper 110 is icing, the icing detection method further includes controlling the alarm device 400 to open, so as to remind the user that the damper 110 is currently icing.

[0078] The icing detection method for a refrigerator 10 provided in this application embodiment involves adding a first coating 112 and / or a second coating 113 to the surface of the body 111 of the air damper 110 of the refrigerator 10. By acquiring the color displayed by the first coating 112 and / or the conductivity of the second coating 113, changes in environmental parameters occurring on the surface of the air damper 110 can be promptly understood, thereby enabling the determination of the icing status of the air damper 110. Thus, when an icing fault is determined to have occurred in the air damper 110, de-icing measures can be taken promptly to prevent abnormal opening and closing of the air damper 110 from affecting the normal cooling of the refrigerator 10's storage compartment.

[0079] This application also provides an ice-forming detection device for a refrigerator 10. For an example, please refer to [link to example]. Figure 5 , Figure 5 This is a schematic diagram of the structure of the icing detection device provided in an embodiment of this application. The icing detection device 20 includes an acquisition module 21 and a processing module 22.

[0080] The acquisition module 21 is used to acquire the color displayed by the first coating 112 and / or the conductivity of the second coating 113; the processing module 22 is used to determine the icing state of the damper 110 based on the color and / or conductivity.

[0081] The icing detection device 20 for the refrigerator 10 provided in this embodiment of the application has a first coating 112 and / or a second coating 113 added to the surface of the body 111 of the air damper 110 of the refrigerator 10. By acquiring the color displayed by the first coating 112 and / or the conductivity of the second coating 113, the changes in environmental parameters occurring on the surface of the air damper 110 can be understood in a timely manner, thereby determining the icing status of the air damper 110. In this way, when it is determined that the air damper 110 has an icing fault, de-icing measures can be taken in a timely manner for the air damper 110, so as to avoid abnormal opening and closing of the air damper 110 and affecting the normal cooling of the storage compartment of the refrigerator 10.
