Any embodiment described in this application as "exemplary" is not necessarily to be construed as being preferred or advantageous over other embodiments. The following description is given to enable any technician in the field to implement and use the present application. In the following description, details are listed for the purpose of explanation. It should be understood that a person of ordinary skill in the art can recognize that the present application can be implemented without using these specific details. In other instances, well-known structures and processes will not be elaborated in detail to avoid obscuring the description of the present application with unnecessary details. Therefore, the present application is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in the present application.

[0044] The present application provides a damper assembly, which is applied to a refrigerator, which may be a single-door, double-door, side-by-side, French, cross-door, or other type of refrigerator. Figure 1 , Figure 1The 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] Among them, the damper 110 includes a main body 111, and the damper 110 also includes a first coating 112 and / or a second coating 113. The first coating 112 is arranged on the first surface 1111 of the main body 111, and is suitable for displaying a corresponding color according to the environmental parameters of the location. The second coating 113 is arranged on the second surface 1112 of the main body 111, and is suitable for having 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 suitable for being connected to the second coating 113 to detect the conductivity of the second coating 113.

[0046] Among them, there are three implementation methods for 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 the 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 realizes the return air from the refrigeration chamber to the storage compartment through the return air duct, and the damper 110 is arranged in the return air duct. By adjusting the opening of the damper 110, the amount of cold air entering the storage compartment can be controlled to achieve temperature control 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 is easily formed on the surface of the damper 110, affecting the normal opening and closing action of the damper 110, which may further affect the refrigeration of the storage compartment of the refrigerator 10, resulting in poor storage effect of food.

[0048] Environmental parameters may include the temperature, humidity and dielectric constant of the environment. When the surface of the first coating 112 is frozen, the environmental parameters of the surface of the first coating 112 will change, thereby causing the color of the first coating 112 to change. It is understandable that by detecting the color displayed by the first coating 112, it is possible to determine whether the surface of the first coating 112 is frozen, thereby determining the freezing condition of the damper 110. In addition, when the surface of the second coating 113 is frozen, the environmental parameters of the surface of the second coating 113 will change, thereby causing the conductivity of the second coating 113 to change. It is understandable that by detecting the conductivity of the second coating 113, it is possible to determine whether the second coating 113 is frozen, thereby determining the freezing condition of the damper 110.

[0049] Optionally, the first coating 112 includes a nanosilver coating. Nanosilver has unique optical properties, especially its surface plasmon resonance effect. When the ambient environmental parameters of the nanosilver particles, such as temperature, humidity, dielectric constant, etc., change, its surface plasmon resonance effect will cause color changes. The freezing of the surface of the first coating 112 will change the environmental parameters around the nanosilver in the coating, thereby causing the color change of the first coating 112. For example, when the surface of the first coating 112 is not frozen, the first coating 112 appears silver-gray; when the surface of the first coating 112 is frozen, the first coating 112 appears white. In the production process, the nanosilver coating can be coated on the first surface 1111 of the body 111 by spraying technology, and the first coating 112 is formed after the nanosilver coating is dried and solidified. Preferably, when spraying nanosilver, the spraying pressure is controlled at 0.5MPa and the spraying time is 1 hour; the particle size of the nanosilver is controlled at 10nm and the concentration is controlled at 0.1mg / 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 400-700 nm and a measurement accuracy of ±1 nm.

[0050] Optionally, the second coating 113 includes a graphene nano coating. Graphene has a thermoelectric effect, and when the environmental parameters around the graphene, such as temperature, humidity, etc., change, its conductivity will change. Ice on the surface of the second coating 113 will change the environmental parameters around the graphene in the coating, thereby causing the conductivity of the second coating 113 to change. In the production process, the graphene nano coating can be coated on the second surface 1112 of the body 111 by dip coating technology, and the second coating 113 is formed after the graphene nano coating is dried and cured. Preferably, when the graphene nano coating is dip coated, the dip coating pressure is controlled at 0.2MPa and the dip coating time is 2 hours. The thickness of the graphene is controlled at 0.3nm and the concentration is controlled at 0.01mg / mL. The conductivity detection device 130 can be embedded in the second coating 113, and optionally, the conductivity detection device 130 is a four-probe conductivity sensor with a measurement range of 0.1-100S / cm and a measurement accuracy of ±0.1S / cm.

[0051] In some embodiments, the first surface 1111 is the windward surface, and the second surface 1112 is the leeward surface. Exemplarily, the refrigerator 10 includes an air duct 200, and the air door 110 is used to be arranged in the air duct 200; when the air door 110 is in a closed state, the first coating 112, the body 111 and the second coating 113 are arranged in sequence along the air flow direction of the air duct 200. In this way, the first coating 112 is arranged on the windward surface of the body 111, and the second coating 113 is arranged on the leeward surface of the body 111. The color displayed by the first coating 112 is detected by the color detection device 120 to determine the icing condition of the windward surface of the air door 110, and the conductivity of the second coating 113 is detected by the conductivity detection device 130 to determine the icing condition of the leeward surface of the air door 110, and then the overall icing condition of the air door 110 can be comprehensively determined according to the icing conditions of the windward surface and the leeward surface of the air door 110.

[0052] The damper assembly 100 provided in the embodiment of the present application is provided with a first coating 112 and / or a second coating 113 on the surface of the body 111 of the damper 110, and by monitoring the color displayed by the first coating 112 and / or the conductivity of the second coating 113, the changes in environmental parameters on the surface of the damper 110 can be timely understood, and the icing condition of the damper 110 can be further determined. In this way, when it is determined that the damper 110 has an icing fault, deicing measures can be taken for the damper 110 in a timely manner to prevent the damper 110 from opening and closing abnormally and affecting the normal refrigeration of the storage compartment of the refrigerator 10.

[0053] The present application also provides a refrigerator, which may be a single-door, double-door, side-by-side, French, cross-door, or other type of refrigerator. Figure 2-Figure 3 , Figure 2 This is a schematic diagram of the structure of a refrigerator provided in an embodiment of the present application. Figure 3 Another structural schematic diagram of a refrigerator provided in an embodiment of the present application. The refrigerator 10 includes the damper assembly 100 and the air duct 200 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 deicing device 300, which is disposed on the air duct 200 and is suitable for deicing the air door 110 when the air door 110 is frozen. Optionally, the deicing 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 suitable for deicing the damper 110 when the damper 110 is frozen. Optionally, the alarm device 400 is an audible and visual alarm, with an audible alarm frequency of 1 kHz and a light alarm brightness of 100 cd.

[0056] The refrigerator 10 provided in the embodiment of the present application is provided with a first coating 112 and / or a second coating 113 on the surface of the body 111 of the damper 110, and by monitoring the color displayed by the first coating 112 and / or the conductivity of the second coating 113, the changes in the environmental parameters on the surface of the damper 110 can be timely understood, and the icing condition of the damper can be further determined. In this way, when it is determined that the damper 110 has an icing failure, deicing measures can be taken for the damper 110 in a timely manner to prevent the damper 110 from opening and closing abnormally and affecting the normal refrigeration of the storage compartment of the refrigerator 10.

[0057] The present application also provides an ice detection method, which is applied to the damper assembly 100 in any of the above embodiments. The refrigerator 10 further includes a controller, which is suitable for connecting with the color detection device 120 and the conductivity detection device 130 to execute the ice detection method. Figure 4 , Figure 4 This is a flow chart of an icing detection method provided in an embodiment of the present application. The icing detection method includes the following steps S101-S102:

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

[0059] Exemplarily, the controller obtains the color displayed by the first coating 112 and / or the conductivity of the second coating 113 at preset intervals for icing determination, so that ice can be detected in time when the damper 110 is frozen.

[0060] Step S102: determining the icing state of the air door 110 according to the color and the electrical conductivity.

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

[0062] Regarding how to determine the icing state of the damper 110 according to the color and the conductivity, the present application provides an embodiment. Exemplarily, in the icing detection method, determining the icing state of the damper 110 according to the color and / or the conductivity includes:

[0063] Obtaining a preset standard color, and determining whether the color currently displayed by the first coating layer 112 is consistent with the preset standard color;

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

[0065] If the color currently 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, it is determined that the damper 110 is frozen.

[0066] Among them, determining the icing state of the damper 110 according to color and / or conductivity includes three implementation methods, the first is to determine the icing state of the damper 110 according to color alone, the second is to determine the icing state of the damper 110 according to conductivity alone; and the third is to determine the icing state of the damper 110 according to a combination of color and conductivity. When the implementation method is to determine the icing state of the damper 110 according to color, the 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, determining that the damper 110 is frozen. When the implementation method is to determine the icing state of the damper 110 according to conductivity, the step may include: obtaining a preset conductivity range, and determining whether the conductivity of the second coating 113 currently exceeds the preset conductivity range; if the conductivity of the second coating 113 exceeds the preset conductivity range, determining that the damper 110 is frozen. 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 currently displayed by the 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 currently displayed by the first coating is inconsistent with the preset standard color, and / or the conductivity of the second coating exceeds the preset conductivity range, it is determined that the damper is frozen.

[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 currently displayed by the 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 currently displayed by the first coating is inconsistent with the preset standard color, and the conductivity of the second coating exceeds the preset conductivity range, it is determined that the damper is frozen.

[0068] It should be noted that when the surface of the first coating 112 presents a preset standard color, it indicates that the surface of the first coating 112 is not currently frozen. The preset standard color can be set by the designer according to the actual parameters of the first coating 112 and other actual data of the refrigerator 10. The preset conductivity range is a conductivity value range. 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 frozen. The preset conductivity range can be set by the designer according to 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 suitable for radiating heat when powered on. After determining that the damper 110 is iced, the ice detection method further includes: controlling the second coating 113 to be powered on to de-ice the damper 110 .

[0070] It is understandable that, in addition to being used for ice detection, the second coating 113 can also be reused for heating to de-ice the damper 110. In this way, the refrigerator 10 does not need to be equipped with a separate heater to de-ice the damper 110, which can save materials, reduce costs, and improve the internal space utilization of the refrigerator 10.

[0071] In a parallel embodiment, the damper 110 includes a second coating 113, and the second coating 113 is suitable for radiating heat to the surrounding when powered on; after determining that the damper 110 is iced, the ice detection method further includes:

[0072] Obtaining the temperature of the damper 110;

[0073] If the temperature of the damper 110 is lower than a preset temperature value, the second coating 113 is controlled to be energized to de-ice the 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 freezing of the damper 110 has reached the preset condition, and the damper 110 needs to be de-iced immediately to prevent the damper 110 from being unable to open and close normally and affecting the refrigeration effect and normal operation of the refrigerator 10.

[0075] It is understandable that, in addition to being used for ice detection, the second coating 113 can also be reused for heating to de-ice the damper 110. In this way, the refrigerator 10 does not need to be equipped with a separate heater to de-ice the damper 110, which can save materials, reduce costs, and improve the internal space utilization of the refrigerator 10.

[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 be turned on to de-ice the damper 110. The heater has a power of 1 kW and a heating temperature of 10°C, for example.

[0077] In some embodiments, after determining that the damper 110 is iced, the ice detection method further includes controlling the alarm device 400 to turn on to remind the user that the damper 110 is currently iced.

[0078] In the ice detection method of the refrigerator 10 provided in the embodiment of the present application, the first coating 112 and / or the second coating 113 are added to the surface of the body 111 of the damper 110 of the refrigerator 10. By obtaining the color displayed by the first coating 112 and / or the conductivity of the second coating 113, the changes in the environmental parameters on the surface of the damper 110 can be timely understood, and then the ice condition of the damper 110 can be determined. In this way, when it is determined that the damper 110 has an ice failure, deicing measures can be taken for the damper 110 in a timely manner to avoid abnormal opening and closing of the damper 110 and affect the normal refrigeration of the storage compartment of the refrigerator 10.

[0079] The present application also provides an ice detection device for a refrigerator 10. For example, see Figure 5 , Figure 5 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 currently 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 according to the color and / or the conductivity.

[0081] In the ice detection device 20 of the refrigerator 10 provided in the embodiment of the present application, the surface of the body 111 of the damper 110 of the refrigerator 10 is additionally provided with a first coating 112 and / or a second coating 113. By obtaining the color displayed by the first coating 112 and / or the conductivity of the second coating 113, the changes in the environmental parameters occurring on the surface of the damper 110 can be timely understood, and then the ice condition of the damper 110 can be determined. In this way, when it is determined that the damper 110 has an ice failure, deicing measures can be taken for the damper 110 in a timely manner to prevent the damper 110 from opening and closing abnormally and affecting the normal refrigeration of the storage compartment of the refrigerator 10.
