Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electronic products, in particular to a mirror demisting method and device, a mirror and a computer storage medium. BACKGROUND

[0002] The mirror surface in a humid environment is very easy to fog, thereby affecting people's use of the mirror. For example, during bathing in a bathroom or using a washbasin, the humid air will quickly condense into dewdrops on the mirror surface, causing the mirror to be unable to be normally used. In view of the phenomenon of mirror fogging, people usually directly use a towel or a tissue to wipe the water mist on the mirror surface, but this demisting method not only has poor demisting effect, but also is easy to spread some bacteria by means of the wiping material, thereby causing adverse effects on the human body.

[0003] In view of this, some mirrors with automatic demisting function are proposed in the existing household market. The mirror only needs to start the mirror demisting function, and the mirror can automatically demist to keep the mirror dry and clean, thereby facilitating the user to use the mirror. However, the existing mirror capable of automatic demisting usually keeps a constant power to heat the mirror surface and maintain the mirror surface at a certain temperature, which is very easy to cause the mirror surface to have high temperature or even burst, thereby not only causing serious economic loss to the user, but also possibly directly harming the user's body safety.

[0004] In summary, it is urgent to improve the reliability of the automatic demisting method for the mirror surface, thereby ensuring the safety of the user using the automatic demisting function of the mirror surface and reducing the use cost of the function. SUMMARY

[0072] or,

[0073] generating the start instruction in a case where a user touch operation is received through a demisting function key preset on the mirror surface.

[0074] In some possible embodiments, the processor 1001 can invoke the computer program stored in the memory 1005, and further perform the following operations:

[0075] demisting a preset local area of the mirror surface at a preset first demisting power;

[0076] demisting the entire area of the mirror surface at a preset second demisting power.

[0077] Based on the running device structure of the hardware running environment involved in the embodiments of the application, the overall idea of the mirror surface demisting method provided by the embodiments of the application is proposed.

[0078] Because people in the process of using the bathroom to take a bath, due to the humid environment, the mirror surface is very easy to fog, thereby affecting the user's use of the mirror. And now for the ordinary mirror, people generally use a towel directly to wipe the water mist on the mirror surface, this kind of defogging method is neither hygienic nor very easy to make bacteria spread through the towel, causing serious harm to the human body. In addition, for the defogging method of the bathroom intelligent mirror is usually through the user to touch the mirror surface or wave hand control to drive the defogging film to open, thereby defogging the mirror surface to keep the mirror dry and clean, convenient for the user to use the mirror.

[0079] However, the current bathroom intelligent mirror adopts the scheme of driving the defogging film to defog the mirror surface, the power of the defogging film is constant in the whole defogging process to make the temperature of the mirror surface continue to rise, and finally the mirror surface will maintain at a high temperature, thereby very easy to cause the mirror surface to be hot or burst, that is, reduce the safety and reliability of the mirror, not only will reduce the service life of the mirror glass, but also will seriously threaten the safety of the human body. And, in the current scheme of using the defogging film to defog the mirror surface, the user needs to wait for a long time from the start of defogging to the removal of the mirror surface mist, the defogging speed is slow, which brings inconvenience to the user. Even if the user starts the anti-fog in advance to avoid long waiting time, but it will cause energy waste due to the pre-opening of the anti-fog, increase the use cost of the user and is not conducive to energy saving and emission reduction.

[0080] In summary, the mirror surface in the humid environment is very easy to fog, thereby affecting people's use of the mirror, for example, people in the process of taking a bath in the bathroom or using the wash basin, the humid air will quickly condense into dew on the mirror surface, causing the mirror to be unable to be used normally. In view of the phenomenon of mirror fogging, people usually directly use a towel or a tissue to wipe the water mist on the mirror surface, but this defogging method not only has poor defogging effect, but also is very easy to spread some bacteria through the wiping material, thereby causing adverse effects on the human body. In view of this, the current home market puts forward some mirrors with automatic defogging function, which only needs to trigger the mirror defogging function to open, and the mirror can automatically defog to keep the mirror dry and clean, thereby facilitating the user to use the mirror. However, the existing mirror that can automatically defog usually continuously heats the mirror surface and maintains the mirror surface at a certain temperature, which is very easy to cause the mirror surface to be hot or even burst, not only will bring more serious economic loss to the user, but also will directly harm the safety of the user's body.

[0081] That is, it is urgent to improve the reliability of the automatic defogging method for the mirror surface, thereby ensuring the safety of the user using the automatic defogging function of the mirror surface and reducing the use cost of the function.

[0082] Based on this, the embodiment of the present application discloses a mirror demisting method. In response to a starting instruction of a mirror demisting function, the mirror is first quickly demisted at a high first demisting power, and then, when the mirror is demisted at the first demisting power for a preset time threshold, the mirror is continuously demisted at a small second demisting power until no water vapor condenses on the mirror to end the demisting operation of the mirror.

[0083] Thus, the mirror demisting method provided by the embodiment of the present application can quickly complete the demisting of the mirror in a short time, which not only achieves the effect of quick demisting, but also reduces the demisting power in the subsequent process to reduce the temperature of the mirror, thereby ensuring the safety, reliability and service life of the mirror when the user uses the automatic demisting function of the mirror, and effectively saving the energy consumed in the process of demisting the mirror, thereby reducing the use cost of the user using the automatic demisting function of the mirror.

[0084] Based on the overall concept of the mirror demisting method provided by the above embodiment of the present application, each embodiment of the mirror demisting method of the present application is proposed.

[0085] It should be noted that the mirror demisting method of the present application is applied to the above-mentioned running device, which can be a mirror including a mirror demisting device, and the mirror can be a mirror with a mirror demisting function. It should be understood that based on different design needs of actual applications, the mirror demisting method of the present application can of course be applied to other terminal devices in different feasible embodiments, and in order to facilitate understanding and description of the technical solutions, the mirror demisting method of the present application will be described below with the mirror as the execution subject of the scheme implementation.

[0086] Please refer to Figure 2 , Figure 2 for the first embodiment of the mirror demisting method of the present application. It should be noted that although the logical sequence is shown in the flowchart, in some cases, the mirror demisting method of the present application can of course execute the steps shown or described in a different order from this place.

[0087] As Figure 2 shown, in the first embodiment of the mirror demisting method of the present application, the mirror demisting method provided by the embodiment of the present application can include the following steps:

[0088] Step S10, in response to a starting instruction of a mirror demisting function, demisting the mirror at a preset first demisting power;

[0089] In this embodiment, after receiving or generating the start-up instruction for the mirror defogging function, the mirror with the mirror defogging function immediately responds to the start-up instruction to start defogging the mirror surface at the pre-set first defogging power.

[0090] It should be noted that in this embodiment and other possible embodiments, the start-up instruction for the mirror defogging function can be triggered by the user touching the mirror surface or performing a specific gesture, or can also be automatically generated by the mirror based on the information data detected by the mirror itself.

[0091] In addition, in this embodiment and other possible embodiments, the pre-set first defogging power can be the power for driving the defogging device (such as a defogging film) installed on the mirror. It should be understood that based on different design needs of actual applications, in different possible implementations, the first defogging power can of course be selected to be of different sizes according to the performance of the defogging device installed on the mirror, and therefore the mirror defogging method of the present application is not limited to the specific size of the first defogging power.

[0092] Step S20, in the case where the defogging time length of the mirror surface at the first defogging power reaches a pre-set time length threshold, continue to defog the mirror surface at a pre-set second defogging power, wherein the second defogging power is less than the first defogging power;

[0093] In this embodiment, after starting to defog the mirror surface at the pre-set first defogging power, the mirror simultaneously records the defogging time length of the mirror surface at the first defogging power, and then in the case where the defogging time length reaches a pre-set time length threshold, the mirror immediately reduces the first defogging power to a pre-set second defogging power that is less than the first defogging power, so as to continue to defog the mirror surface at the second defogging power.

[0094] It should be noted that in this embodiment and other possible embodiments, like the pre-set first defogging power described above, the pre-set second defogging power can also be the power for driving the defogging device (such as a defogging film) installed on the mirror, and the second defogging power is less than the first defogging power, for example, the second defogging power is preferably half of the first defogging power. It should be understood that based on different design needs of actual applications, in different possible implementations, the second defogging power can of course be selected to be of different sizes according to the performance of the defogging device installed on the mirror, and therefore the mirror defogging method of the present application is not limited to the specific size of the second defogging power, as long as the second defogging power is less than the first defogging power described above.

[0095] Furthermore, in this embodiment and some other feasible embodiments, the aforementioned preset time threshold can be the time required for the mirror to be heated by the first defogging power until the entire area of ​​the mirror surface covered by the defogging film is defogged. It should be understood that, based on the different types of defogging films used in different feasible embodiments in actual use, the magnitude of the first defogging power, the size of the area covered by the defogging film on the mirror surface, and the temperature and humidity information of the humid environment in which the mirror is located, these may not be entirely the same. Therefore, the specific value of the preset time threshold is naturally flexibly set to adapt to different usage scenarios. Thus, the mirror defogging method provided in this application embodiment does not limit the specific value of the preset time threshold.

[0096] Step S30: Defogging of the mirror surface ends when it is confirmed that there is no water vapor condensation on the mirror surface.

[0097] In this embodiment, while the mirror continues to defog the mirror surface according to the second defogging power described above, the mirror also simultaneously detects whether there is water vapor condensation on the mirror surface. Thus, when the mirror detects and determines that water vapor condensation has occurred on the mirror surface, it ends the defogging operation on the mirror surface.

[0098] It should be noted that, in this embodiment and some other feasible embodiments, in addition to simultaneously detecting whether there is water vapor condensation on the mirror surface while continuing to defog the mirror surface according to the second defogging power, the mirror can also start detecting whether there is water vapor condensation on the mirror surface while defogging the mirror surface according to the first defogging power.

[0099] For example, such as Figure 3 As shown, after the mirror activates its defogging function in response to the defogging function activation command, it powers the defogging film drive circuit through its central controller, thereby gradually increasing the power of the defogging film to heat it. This continues until the power of the defogging film is increased to the first defogging power and maintained at that power for a preset time threshold, until the mirror surface temperature reaches a set heat value. Then, the mirror uses PWM pulse width modulation technology to reduce the average power, lowering the first defogging power to a second defogging power. Defogging continues at this second power until no water vapor condenses on the entire mirror surface, confirming that the defogging of the mirror surface is complete.

[0100] Furthermore, in some alternative embodiments, step S30 described above may include:

[0101] If it is determined that there is no water vapor condensation on the mirror surface, the second defogging power is reduced to zero to end the defogging of the mirror surface.

[0102] In the embodiment, the mirror continues to detect whether water vapor condenses on the mirror surface during the process of defogging the mirror surface according to the smaller second defogging power. When it is detected that water vapor condenses on the mirror surface, the mirror immediately reduces the second defogging power to zero, thereby ending the defogging operation for the mirror surface.

[0103] For example, in the embodiment, when the mirror has reached the preset time threshold and reduced the first defogging power to the second defogging power, and then continues to drive the defogging film to defog the mirror surface according to the second defogging power, the mirror always keeps defogging the mirror surface according to the second defogging power until it is detected that there is no water vapor condensation on the mirror surface. At this time, the mirror further directly reduces the second defogging power to zero, thereby ending the current defogging operation for the mirror surface.

[0104] Further, in some optional embodiments, in addition to directly reducing the second defogging power to zero to end the defogging operation when it is confirmed that there is no water vapor condensation on the mirror surface, the mirror can gradually reduce the second defogging power in combination with the real-time dew point temperature of the mirror surface when starting to defog the mirror surface according to the second defogging power, until the second defogging power is reduced to zero to end the defogging operation for the mirror surface.

[0105] Based on this, the mirror defogging method of the application can further include, after the step of “continuing to defog the mirror surface according to the preset second defogging power”:

[0106] Step A, determining the real-time dew point temperature of the mirror surface, and adjusting the second defogging power in real time according to the real-time dew point temperature to obtain a third defogging power;

[0107] In the embodiment, after the mirror defogs the mirror surface according to the smaller second defogging power, the mirror also synchronously monitors and determines the real-time dew point temperature of the mirror surface, and then adjusts the size of the second defogging power in real time based on the size change of the real-time dew point temperature (for example, gradually reduces the second defogging power when the real-time dew point temperature becomes smaller, or gradually increases the second defogging power when the real-time dew point temperature becomes larger), so as to take the power adjusted in real time as the third defogging power.

[0108] Step B, defogging the mirror surface according to the third defogging power, wherein the third defogging power is smaller than the second defogging power;

[0109] In the embodiment, after the mirror adjusts the second defogging power to the third defogging power based on the real-time dew point temperature of the mirror surface, the mirror continues to drive the defogging film heating on the mirror surface to defog the mirror surface according to the third defogging power.

[0110] It should be noted that in the embodiment and other possible embodiments, the third defogging power obtained by the mirror adjusting the second defogging power based on the real-time dew point temperature of the mirror surface can also be greater than or equal to the second defogging power, but in the case that the third defogging power is greater than the second defogging power, the third defogging power is always less than or equal to the first defogging power.

[0111] Step C, in the case that it is determined that there is no water vapor condensation on the mirror surface, the third defogging power is reduced to zero to end the defogging of the mirror surface.

[0112] In the embodiment, during the process that the mirror continues to defog the mirror surface according to the third defogging power obtained by adjusting the size of the second defogging power, if the mirror determines that there is no water vapor condensation on the mirror surface and the third defogging power is not equal to zero at this time, the mirror directly reduces the third defogging power to zero to end the current defogging operation of the mirror surface.

[0113] It should be noted that in the embodiment and other possible embodiments, as shown in Figure 4 In the traditional and conventional defogging mode, the power of the defogging film needs to be kept at P1 to heat the defogging film at a constant power until the defogging of the mirror surface is completed, so the heat calculation in the traditional and conventional defogging mode is Q1=P1T, where T is the time consumption of the whole process from the start of the defogging of the mirror surface to the completion of the defogging.

[0114] However, in the mirror defogging method of the present application (corresponding to the rapid defogging power curve shown in the dashed line form in the figure), after the mirror starts the defogging function in response to the start instruction of the defogging function, the defogging film heats at a high first defogging power P2 during 0 to a preset time threshold T1, and then decreases from the first defogging power P2 to a second defogging power P1 at T1, so that the defogging film only heats at a low second defogging power P1 between T1 and T2 to defog the mirror surface. That is, there is a power change process when the mirror defogs the mirror surface. First, the defogging film heats at a high first defogging power P2 to rapidly increase the temperature of the area of the mirror surface covered by the defogging film, and the heat generated at this time is calculated as follows:

[0115]

[0116] At this time, the heat required by the mirror to remove the mirror surface fog: Q3 = cmΔt, wherein c is the specific heat capacity, unit J / (kg·K), m is the mass of the object, unit kg, and Δt is the temperature difference, unit K.

[0117] Considering that the defogging film is pasted on the back of the mirror in actual use, the heat conducted to the front of the mirror by the defogging film heating is as follows:

[0118]

[0119] wherein Δt is the temperature difference, unit K, λ is the thermal conductivity, unit W / (m·K), S is the area, unit m2, and L is the thickness, unit m.

[0120] And in the process of heat conduction from the defogging film heating to the front of the mirror, the heat is lost due to the internal factors of the object, and the difference between Q4 and Q3 is different for different mirrors due to different sizes and thicknesses of the mirrors, so Q4 < Q3 < Q2. Therefore, to ensure that the heat generated by the defogging film can remove all the fog in the area covered by the defogging film on the mirror surface within 0 to T1 time, thereby speeding up the defogging speed of the mirror surface, the first defogging power of the mirror needs to be doubled to reach P2, and at the T1 time node, the first defogging power P2 is lowered back to the second defogging power P1, and then the mirror defogs the entire area of the mirror surface (herein the area covered by the defogging film) with the second defogging power. In this way, the mirror surface can not only achieve the effect of fast defogging, but also reduce power consumption to save energy.

[0121] In this embodiment, during T1 to T2, the power of the defogging film will gradually decrease to a low steady state, so that the temperature of the defogging film also decreases, but the total heat value remains at a higher level than the dew point temperature. At this time, the heat calculation formula is as follows:

[0122]

[0123] Therefore, in this embodiment, the mirror defogging method provided by the embodiment can quickly complete the defogging of the mirror surface in a short time, which not only achieves the effect of fast defogging, but also reduces the defogging power in the subsequent process to reduce the temperature of the mirror surface, thereby ensuring the safety, reliability and service life of the mirror when the user uses the automatic defogging function of the mirror, and effectively saving the energy consumed in the process of defogging the mirror surface, thereby reducing the use cost of the user using the automatic defogging function of the mirror.

[0124] In addition, in this embodiment and other feasible embodiments, for example, Figure 5As shown, the mirror can use PWM pulse width modulation technology to change the corresponding frequency by changing the time width of the pulse to disperse the effective electrical signal into discrete form to reduce the average power of the electrical signal transmission in the process of defogging the mirror surface.

[0125] Further, based on the first embodiment of the mirror defogging method of the present application, a second embodiment of the mirror defogging method of the present application is proposed.

[0126] In the present embodiment, the step of "determining the real-time dew point temperature of the mirror surface" described above can include:

[0127] Real-time detection of the mirror surface temperature information of the mirror surface and the environmental temperature and humidity information of the installation environment in which the mirror surface is located;

[0128] Calculation according to the mirror surface temperature information and the environmental temperature and humidity information to determine the real-time dew point temperature of the mirror surface.

[0129] In the present embodiment, the mirror can real-time detect the mirror surface temperature information of the mirror surface and the environmental temperature and humidity information of the installation environment in which the mirror surface is located during the process of defogging the mirror surface according to the first defogging power, and / or during the process of defogging the mirror surface according to the second defogging power. Then, the mirror calculates the real-time dew point temperature of the mirror surface at the current time through the detected mirror surface temperature information and the environmental temperature and humidity information.

[0130] Exemplarily, as Figure 6 shown, when the mirror drives the defogging film heating according to the second defogging power P1 described above to defog the whole mirror surface, the mirror also synchronously real-time detects the environmental temperature and humidity (including the environmental temperature and relative humidity) of the installation environment in which the mirror surface is located, and real-time detects the mirror surface temperature of the mirror surface. Then, the mirror can calculate whether the mirror surface reaches the dew point temperature of water vapor condensation through the following formula with the real-time detected environmental temperature and relative humidity:

[0131]

[0132] wherein γ is:

[0133]

[0134] wherein the temperature T and the dew point temperature T d are in ℃, the relative humidity RH is in percentage, In is the natural logarithm, and the constants a and b are respectively: a = 17.27; b = 237.7 ℃.

[0135] It should be noted that in this embodiment and other feasible embodiments, during the later stage of defogging from node T1 to node T2, the temperature and humidity of the installation environment around the mirror change in real time, and the water vapor in the air dissipates in real time, causing the dew point temperature to drop accordingly. At this time, the mirror needs to reduce the second defogging power according to the real-time decrease in the dew point temperature of the mirror surface. By adjusting the defogging power in real time, both power consumption can be reduced and the effect of preventing fog formation on the mirror surface can be maintained, which is beneficial for secondary energy saving.

[0136] Furthermore, in this embodiment and other feasible embodiments, the method for defogging a mirror in this application may further include:

[0137] Detect whether the real-time dew point temperature drops to zero;

[0138] It is determined that there is no water vapor condensation on the mirror surface when the real-time dew point temperature is detected to have dropped to zero.

[0139] In this embodiment, after the mirror detects and calculates the real-time dew point temperature of the mirror surface through the above calculation process, the mirror further continuously detects whether the calculated real-time dew point temperature has dropped to zero. Thus, once the mirror detects that the real-time dew point temperature has dropped to zero, it can determine that there is no water vapor condensation on the mirror surface, that is, the current defogging of the mirror surface is completed.

[0140] For example, when the mirror detects that the real-time dew point temperature of the mirror surface is equal to 0, it can be concluded that there is no water vapor condensation on the mirror surface at this time - the defogging is completed. Therefore, the mirror will also reduce the second defogging power / third defogging power to 0, thereby turning off the current defogging function for the mirror surface.

[0141] Furthermore, based on the first and / or second embodiments of the mirror defogging method of this application described above, a third embodiment of the mirror defogging method of this application is proposed.

[0142] In this embodiment, the mirror defogging method of this application may further include, before the above-mentioned step of "responding to the start command of the mirror defogging function to defog the mirror according to a preset first defogging power":

[0143] When the temperature of the mirror surface is detected to reach the real-time dew point temperature, an automatic start command for the mirror surface defogging function is generated.

[0144] In the embodiment, the mirror can automatically generate the starting instruction for the mirror defogging function based on the detection of the real-time dew point temperature of the mirror surface. That is, after the mirror calculates the real-time dew point temperature of the mirror surface based on the real-time detected temperature information of the mirror surface and the environmental temperature and humidity information according to the calculation process described in the second embodiment, if it is further detected that the temperature of the mirror surface reaches the real-time dew point temperature, it is confirmed that the mirror surface will condense water vapor at this time, and the mirror automatically generates the starting instruction for the mirror defogging function possessed by the mirror. Then, the mirror can perform the defogging operation on the mirror surface according to the process described in the first embodiment until the defogging is completed.

[0145] It should be noted that in the embodiment and other possible embodiments, the temperature of the mirror surface can be extracted from the real-time temperature information of the mirror surface detected by the mirror. In addition, the mirror can detect the temperature information of the mirror surface and the environmental temperature and humidity information described above through a temperature sensor and a humidity sensor configured or connected to the mirror.

[0146] Optionally, in the embodiment and other possible embodiments, the mirror can generate the starting instruction for the mirror defogging function through intelligent interaction with the user in addition to automatically generating the starting instruction for the mirror defogging function by detecting the real-time dew point temperature of the mirror surface.

[0147] Based on this, the mirror defogging method of the present application can further include, before the step of “responding to the starting instruction for the mirror defogging function to defog the mirror surface at a preset first defogging power” described above:

[0148] In the case that the user touch operation is received through the mirror pre-set defogging function button, the starting instruction is generated.

[0149] In the embodiment, the mirror is pre-configured with a virtual / physical defogging function button on the mirror surface or other area, so that the user can perform touch operation on the defogging function. Therefore, the mirror generates the starting instruction for the mirror defogging function possessed by the mirror immediately in the case that the touch operation performed by the user is received based on the virtual / physical defogging function button. Then, the mirror can perform the defogging operation on the mirror surface according to the process described in the first embodiment until the defogging is completed.

[0150] It should be noted that in the present embodiment, the mirror can also collect gesture images of the user in front of the mirror surface through a pre-installed image collection device, so as to determine the user's intention to turn on the mirror defogging function by analyzing the gesture images, and then generate a start instruction for the mirror defogging function. Alternatively, the mirror can also collect voice information issued by the user through a pre-installed sound collection device, so as to determine the user's intention to turn on the mirror defogging function by analyzing the voice information, and then generate a start instruction for the mirror defogging function. In addition, the mirror can also be connected to the user's smart terminal device through Internet of Things technology, so as to generate a start instruction by receiving the instruction sent by the smart terminal device.

[0151] As shown in the example, Figure 7 The mirror can generate a start instruction for the mirror defogging function it has by receiving the electrical signal generated by the user touching the defogging key (the defogging function key mentioned above), so as to manually turn on the defogging for the mirror surface. Alternatively, the mirror can also calculate the real-time dew point temperature of the mirror surface by detecting the temperature of the mirror surface and the ambient temperature and humidity of the environment in which the mirror surface is located. In this way, when the temperature of the mirror surface reaches the real-time dew point temperature, a start instruction for the mirror defogging function is automatically generated.

[0152] Then, the mirror responds to the start instruction mentioned above to turn on the defogging film driving circuit configured by itself, and increases the defogging power to the first defogging power P2 to heat the defogging film to defog the central area of the mirror surface covered by the defogging film from the current time to the preset time threshold T1. Then, immediately reduce the first defogging power P2 to the second defogging power P1 when reaching the preset time threshold T1, so that only the second defogging power P1 is used to defog the entire mirror surface in the subsequent until the defogging is completed.

[0153] It should be noted that in the present embodiment and other possible embodiments, the mirror can only cover the central area of the mirror surface with the defogging film. Alternatively, the mirror can of course also cover the entire area of the mirror surface with the defogging film.

[0154] Based on this, in the mirror defogging method of the present application, the step of "defogging the mirror surface according to the preset first defogging power" can include:

[0155] Defogging a preset local area of the mirror surface according to the preset first defogging power;

[0156] In the present embodiment, when the mirror defogging film is heated to defog the mirror surface according to the above-mentioned higher first defogging power, only the preset local area of the mirror surface is defogged by the defogging film heated according to the first defogging power.

[0157] It should be noted that in the embodiment, the preset local area includes but is not limited to the central area of the mirror.

[0158] Further, the step of continuing to defog the mirror according to the preset second defogging power can include:

[0159] Defogging the entire area of the mirror according to the preset second defogging power.

[0160] In the embodiment, when the mirror defogs the mirror according to the lower second defogging power of the defogging film heating, the mirror defogs the entire area of the mirror according to the second defogging power of the defogging film heating.

[0161] For example, in the embodiment and other possible embodiments, at the time of 0 to T1, the mirror defogs only the central area of the mirror by driving the defogging film heating of the central area of the mirror according to the first defogging power P1, and at the time of T1 to T2, the mirror defogs the entire area of the mirror by driving the defogging film heating of the entire area of the mirror according to the second defogging power P2.

[0162] In the embodiment, when the mirror defogs using a higher power, only the local area of the mirror is defogged, so that the defogging of the local area of the mirror can be completed in a short time, and the effect of quickly defogging the mirror for use by the user is achieved. After the local area of the mirror is defogged, the power is reduced to reduce the temperature of the mirror, which can effectively ensure the reliability and service life of the mirror, and save energy and reduce the use cost of the user using the defogging function of the mirror.

[0163] In addition, the embodiment of the application also provides a mirror defogging device. Please refer to Figure 8 In a possible embodiment, the mirror defogging device of the application can include:
