Description

Technical Field

[0001] The present invention relates to the technical field of heating equipment, and in particular to a glass heating device, a refrigeration device and a control method for the glass heating device. Background Art

[0002] The glass doors of some refrigeration equipment, such as refrigerators, freezers, display cabinets and sales cabinets, often produce fog and frost on the glass surface due to the changes in temperature and humidity between the inner and outer surfaces. Currently, the methods used to defog and defrost the glass mainly include electrically heating the glass, blowing the glass with a fan and directly wiping the glass.

[0003] However, electrically heated glass uniformly heats the entire defrost and defogging area, which can easily lead to overheating of local areas and insufficient defrosting and defogging. In addition, the electric heating element is in direct contact with the equipment, which can easily damage the equipment.

[0004] Fan defrosting and defrosting uses fans to blow hot air to the fog and frosting areas. The defrosting and defrosting effects are greatly affected by wind direction and wind speed. Hot air is easily unevenly distributed, resulting in unstable defrosting and defrosting effects. In addition, the operation of the fan is often accompanied by vibration and noise, which affects the operating stability and service life of the refrigeration equipment.

[0059] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present invention and to enable the scope of the present invention to be fully communicated to those skilled in the art.

[0060] The glass doors of some refrigeration equipment, such as refrigerators, freezers, display cabinets and sales cabinets, often produce fog and frost on the glass surface due to the changes in temperature and humidity between the inner and outer surfaces. Currently, the methods used to defog and defrost the glass mainly include electrically heating the glass, blowing the glass with a fan and directly wiping the glass.

[0061] However, electrically heated glass uniformly heats the entire defrost and defogging area, which can easily lead to overheating of local areas and insufficient defrosting and defogging. In addition, the electric heating element is in direct contact with the equipment, which can easily damage the equipment.

[0062] Fan defrosting and defrosting uses fans to blow hot air to the fog and frosting areas. The defrosting and defrosting effects are greatly affected by wind direction and wind speed. Hot air is easily unevenly distributed, resulting in unstable defrosting and defrosting effects. In addition, the operation of the fan is often accompanied by vibration and noise, which affects the operating stability and service life of the refrigeration equipment. The above-mentioned defrosting and defrosting methods all have problems such as uneven defrosting and defrosting and energy waste.

[0063] Based on the above technical problems, an embodiment of the present invention is proposed. The embodiment of the present invention may include at least two infrared heaters 1, at least two first sensor modules 2, at least two second sensor modules 3, an environmental sensor module 4, and a controller 5. Each of the infrared heaters 1 faces a different glass partition 601 on the glass door body 6, so that each of the infrared heaters 1 forms a thermal radiation coverage on the associated glass partition 601 when working. The first sensor module 2 is located on the inner side of the glass door body 6, and each of the first sensor modules 2 is located in a different glass partition 601 to detect the first temperature and humidity data in each of the glass partitions 601. The second sensor module 3 is located on the outer side of the glass door body 6, and each of the second sensor modules 3 is located in a different glass partition 601 to detect the second temperature and humidity data in each of the glass partitions 601. The environmental sensor module 4 is located outside the glass door body 6 to detect environmental temperature and humidity data. The infrared heater 1, the first sensor module 2, the second sensor module 3 and the environment sensor module 4 are electrically connected to the controller 5, respectively, so that the controller 5 controls the heating state of the infrared heater 1 through the first temperature and humidity data, the second temperature and humidity data and the environment temperature and humidity data. Thus, the glass door body 6 can be divided into regions, and the infrared heater 1 can be used to heat the glass partition 601 that needs to be defogged and defrosted, thereby improving the uniformity and efficiency of defogger and defrost, and avoiding energy waste.

[0064] Reference Figure 1 and Figure 4 As shown, an embodiment of the present invention provides a glass heating device, which may include at least two infrared heaters 1, at least two first sensor modules 2, at least two second sensor modules 3, an environmental sensor module 4, and a controller 5. Each of the infrared heaters 1 faces a different glass partition 601 on the glass door body 6, so that each of the infrared heaters 1 forms a thermal radiation coverage for the associated glass partition 601 when working. The first sensor module 2 is located on the inner side of the glass door body 6, and each of the first sensor modules 2 is located in a different glass partition 601 to detect the first temperature and humidity data in each of the glass partitions 601. The second sensor module 3 is located on the outer side of the glass door body 6, and each of the second sensor modules 3 is located in a different glass partition 601 to detect the second temperature and humidity data in each of the glass partitions 601. The environmental sensor module 4 is located outside the glass door body 6 to detect environmental temperature and humidity data. The infrared heater 1 , the first sensor module 2 , the second sensor module 3 and the environment sensor module 4 are electrically connected to the controller 5 respectively, so that the controller 5 controls the heating state of the infrared heater 1 through the first temperature and humidity data, the second temperature and humidity data and the environment temperature and humidity data.

[0065] In an embodiment of the present invention, the infrared heater 1 is a device that uses infrared radiation for heating. It uses electrical energy to convert electric current into infrared radiation energy, which is transferred to the heated object through radiation to increase its temperature. The glass door body 6 can be divided into multiple glass partitions 601 in advance, and each of the glass partitions 601 is associated with an infrared heater 1. For example, the area division of the glass door body 6 can be determined based on the size of the glass door body 6 and the maximum emission power (maximum heating power) of a single infrared heater 1. Each of the infrared heaters 1 faces different glass partitions 601 on the glass door body 6, so that each infrared heater 1 can form thermal radiation coverage for the associated glass partition 601, that is, uniform heating of the associated glass partition 601 can be achieved through one infrared heater 1.

[0066] The first sensor module 2 is used to detect the first temperature and humidity data of the inner side surface of each glass partition 601 (which can be understood as the inner surface of the glass of the corresponding glass partition 601), and each of the first sensor modules 2 is located in different glass partitions 601. The first sensor module 2 may include a first temperature and humidity sensor, or the first sensor module 2 may include a first temperature sensor and a first humidity sensor. The second sensor module 3 is used to detect the second temperature and humidity data of the outer side surface of each glass partition 601 (which can be understood as the outer surface of the glass of the corresponding glass partition 601), and each of the second sensor modules 3 is located in different glass partitions 601. The second sensor module 3 may include a second temperature and humidity sensor, or the second sensor module 3 may include a second temperature sensor and a second humidity sensor. The environment sensor module 4 is used to detect the temperature and humidity data outside the glass partition 601, that is, the temperature and humidity data of the environment where the refrigeration equipment is located. The environment sensor module 4 may include an environment temperature and humidity sensor, or the environment sensor module 4 may include an environment temperature sensor and an environment humidity sensor.

[0067] Therefore, for each glass partition 601 in the glass door body 6, each glass partition 601 is provided with the following structure: an infrared heater 1 for uniformly radiating heat to the glass partition 601, a first sensor module 2 for detecting the temperature and humidity of the inner side of the glass partition 601, and a second sensor module 3 for detecting the temperature and humidity of the outer side of the glass partition 601. All infrared heaters 1, all first sensor modules 2, the second sensor modules 3 and the environment sensor module 4 are electrically connected to the controller 5, respectively. Thus, the first temperature and humidity data, the environment temperature and humidity data and the second temperature and humidity data can be received by the controller 5, and the heating state of the infrared heater 1 associated with different glass partitions 601 can be controlled according to the above temperature and humidity data. Among them, the heating state may include but is not limited to the state of starting heating and stopping heating.

[0068] The embodiment of the present invention further discloses a refrigeration device, which comprises a glass door body 6 and the glass heating device as described in the above embodiment of the invention.

[0069] In the embodiment of the present invention, the refrigeration equipment may include but is not limited to refrigerators, freezers, vending cabinets and other refrigeration equipment, wherein the environmental temperature and humidity module may be installed on the outside of the refrigeration equipment, or in the outer frame of the glass door body 6 and other areas. There is a certain distance between the infrared heater 1 and the inner side of the glass door body 6, and the distance between the infrared heater 1 and the inner side of the glass door body 6 is controlled to be between a few centimeters and more than ten centimeters, so that the heat transfer efficiency of the infrared heater 1 to the glass partition 601 can be guaranteed, and the normal opening and closing of the glass door body 6 is not affected.

[0070] In summary, the embodiment of the present invention discloses a glass heating device and a refrigeration device, and the embodiment of the present invention may include at least two infrared heaters 1, at least two first sensor modules 2, at least two second sensor modules 3, an environmental sensor module 4, and a controller 5. Each of the infrared heaters 1 faces a different glass partition 601 on the glass door body 6, so that each of the infrared heaters 1 forms a thermal radiation coverage for the associated glass partition 601 when working. The first sensor module 2 is located on the inner side of the glass door body 6, and each of the first sensor modules 2 is located in a different glass partition 601 to detect the first temperature and humidity data in each of the glass partitions 601. The second sensor module 3 is located on the outer side of the glass door body 6, and each of the second sensor modules 3 is located in a different glass partition 601 to detect the second temperature and humidity data in each of the glass partitions 601. The environmental sensor module 4 is located outside the glass door body 6 to detect environmental temperature and humidity data. The infrared heater 1, the first sensor module 2, the second sensor module 3 and the environment sensor module 4 are electrically connected to the controller 5, respectively, so that the controller 5 controls the heating state of the infrared heater 1 through the first temperature and humidity data, the second temperature and humidity data and the environment temperature and humidity data. Thus, the glass door body 6 can be divided into regions, and the infrared heater 1 can be used to heat the glass partition 601 that needs to be defogged and defrosted, thereby improving the uniformity and efficiency of defogger and defrost, and avoiding energy waste.

[0071] In some embodiments, the controller 5 can be a single controller or a controller cluster. For example, the controller 5 can include a main controller and multiple sub-controllers electrically connected to the main controller. The number of the sub-controllers is adapted to the number of glass partitions 601. Thus, the infrared heater 1, the first sensor module 2, and the second sensor module 3 corresponding to each glass partition 601 are electrically connected to the sub-controllers, respectively. No excessive restrictions are placed on the architecture of the controller 5.

[0072] Reference Figure 2 As shown, the embodiment of the present invention further discloses a control method for a glass heating device, the refrigeration device may include the refrigeration device as described in the above embodiment of the invention, the control method is applied to the controller 5, and the control method includes:

[0073] S201 , obtaining first temperature and humidity data of all glass partitions 601 of the glass door body 6 , second temperature and humidity data of all glass partitions 601 , and ambient temperature and humidity data.

[0074] In an embodiment of the present invention, the first temperature and humidity data may include first temperature data and first humidity data. The first temperature and humidity data is used to characterize the temperature and humidity on the inner surface of the glass of the glass partition 601. The second temperature and humidity data may include second temperature data and second humidity data, and the second temperature and humidity data is used to characterize the temperature and humidity on the outer surface of the glass of the glass partition 601. The ambient temperature and humidity data may include an ambient temperature value and an ambient humidity value, and the ambient temperature and humidity data is used to characterize the ambient temperature and humidity at the refrigeration device. Thus, the controller 5 can receive the ambient temperature and humidity data, the first temperature and humidity data, and the second temperature and humidity data of all glass partitions 601.

[0075] S202 , determining fogging and frost risk results of each glass partition 601 according to the first temperature and humidity data of each glass partition 601 , the second temperature and humidity data of each glass partition 601 , and the ambient temperature and humidity data.

[0076] In the embodiment of the present invention, the fogging and frosting risk result may include the existence of fogging risk, the existence of frosting risk, the absence of fogging and frosting risk, etc. Among them, the main reason for the fogging of the glass of the refrigeration equipment is the difference in temperature and humidity inside and outside the refrigeration equipment. For example, a large difference in temperature between the inside and outside of the glass door body 6, or a high humidity on the inner side of the glass door body 6, may cause the outer surface of the glass of the glass door body 6 to fog.

[0077] The frosting of the glass of the refrigeration equipment refers to the phenomenon that the water vapor in the air condenses into small ice crystals on the outer surface of the glass of the glass door body 6, which usually occurs when the air humidity is high or the temperature is below 0 degrees Celsius. Therefore, the fogging temperature and humidity conditions corresponding to the fogging phenomenon of the glass partition 601 and the frosting temperature and humidity conditions corresponding to the frosting phenomenon can be set in advance according to the equipment test results. Therefore, the first temperature and humidity data, the second temperature and humidity threshold value and the ambient temperature and humidity data of each glass partition 601 obtained within the preset time period can be integrated according to the fogging temperature and humidity conditions and the frosting temperature and humidity conditions, so as to obtain the fogging and frosting risk results of each glass partition 601.

[0078] S203 , determining a heating strategy of the associated infrared heater 1 according to the fogging and frost risk results of each glass partition 601 .

[0079] In the embodiment of the present invention, after the fogging and frosting risk result is determined, a heating strategy of the infrared heater 1 associated with the glass partition 601 corresponding to the fogging and frosting risk result can also be matched. In one example, when it is determined that the corresponding glass partition 601 has a fogging risk, a heating strategy corresponding to the glass partition 601 having a fogging risk can be matched. This heating strategy is used as the heating strategy of the infrared heater 1 that heats the corresponding glass partition 601.

[0080] In another example, when it is determined that the corresponding glass partition 601 has a risk of frost formation, a heating strategy corresponding to the glass partition 601 having a risk of frost formation may be matched, and this heating strategy is used as a heating strategy for the infrared heater 1 that heats the corresponding glass partition 601 .

[0081] By analogy, according to the fogging and frost risk results of each glass partition 601 , the heating strategies of the infrared heaters 1 associated with each glass partition 601 are determined respectively.

[0082] S204 , driving the infrared heaters 1 associated with each glass partition 601 to operate according to the heating strategy.

[0083] In the embodiment of the present invention, the controller 5 can drive the infrared heater 1 associated with each glass partition 601 to operate according to the corresponding heating strategy. For example, when it is determined that the glass partition 601 has no risk of fogging and frosting, it can be determined that the heating strategy corresponding to the risk of no fogging and frosting is to stop the operation of the infrared heater 1. For another example, when it is determined that the glass partition 601 has a risk of fogging, it can be determined that the heating strategy corresponding to the risk of fogging is to determine that the infrared heater 1 of the corresponding glass partition 601 is heated according to a preset defrosting power. For another example, when it is determined that the glass partition 601 has a risk of frosting, it can be determined that the heating strategy corresponding to the risk of frosting is to determine that the infrared heater 1 of the corresponding glass partition 601 is heated according to a preset defrosting power.

[0084] Thus, the glass door body 6 can be divided into regions, and the infrared heater 1 can be used to heat the glass partition 601 that needs to be defogged and defrosted. Among them, infrared rays have high energy and penetration ability, and can quickly heat the surface of the glass partition 601, so that the fog and frost layer can evaporate or melt quickly. In this way, the uniformity and heating efficiency of defogger and defrost can be improved, and energy waste can be avoided by accurately heating different glass partitions 601. In addition, the above method steps can ensure that each glass partition 601 of the glass body always remains clear and transparent, and fogging or frosting will not occur, thereby providing good display conditions for the goods located in the refrigeration equipment. In addition, infrared zoning defogger and defrost can achieve uniform heating of the corresponding glass area, reduce the thermal stress of the glass door body 6, and further extend the service life of the glass door.

[0085] Reference Figure 3 As shown, the embodiment of the present invention further discloses another control method of a glass heating device, the control method comprising:

[0086] S301 , obtaining first temperature and humidity data of all glass partitions 601 of the glass door body 6 , second temperature and humidity data of all glass partitions 601 , and ambient temperature and humidity data.

[0087] In the embodiment of the present invention, the first temperature and humidity data may include first temperature data and first humidity data. The first temperature and humidity data is used to characterize the temperature and humidity on the inner surface of the glass of the glass partition 601. The second temperature and humidity data may include second temperature data and second humidity data, and the second temperature and humidity data is used to characterize the temperature and humidity on the outer surface of the glass of the glass partition 601.

[0089] The ambient temperature and humidity data may include ambient temperature values ​​and ambient humidity values, and the ambient temperature and humidity data are used to characterize the ambient temperature and humidity at the refrigeration device. Thus, the controller 5 may receive the ambient temperature and humidity data, the first temperature and humidity data, and the second temperature and humidity data of all glass partitions 601 .

[0090] S302: Calculate the dew point temperature according to the ambient temperature and humidity data.

[0091] In the embodiment of the present invention, the dew point temperature refers to the temperature at which the air is cooled to saturation under the condition that the water vapor content in the air remains unchanged and the air pressure is constant. It is used to reflect the humidity in the ambient air. For example, when the ambient temperature and humidity values ​​in the current environment are known, the corresponding dew point temperature can be calculated according to the following formula (1) and formula (2):

[0092] Td=[b*α(T,RH)] / [a-α(T,RH)] Formula (1)

[0093] α(T,RH)=(a*T) / (b+T)+ln(RH / 100) Formula (2)

[0094] In the above formula (1) and formula (2), a and b are constants, where a is 17.27 and b is 237.7; Td refers to the dew point temperature, T refers to the current ambient temperature value, and RH refers to the current ambient humidity value. For example, when the current ambient temperature value is 25 degrees Celsius and the current ambient humidity value is 60%, the calculated dew point temperature is 16.45 degrees Celsius.

[0095] S303 , determining the fogging risk result of each glass partition 601 according to the dew point temperature, the first temperature and humidity data of each glass partition 601 , and the second temperature and humidity data of each glass partition 601 .

[0096] In the embodiment of the present invention, when the temperature of the outer surface of the glass of the glass partition 601 is high and has a large difference with the temperature of the inner surface of the glass of the glass partition 601, and the temperature of the inner surface of the glass of the glass partition 601 is lower than the dew point temperature, or when the humidity of the inner surface of the glass of the glass partition 601 is high, the glass surface of the glass partition 601 is easily fogged.

[0097] In some embodiments, when the temperature difference between the dew point temperature and the first temperature value of the glass partition 601 is within the first temperature range, and the temperature difference between the second temperature value of the corresponding glass partition 601 and the first temperature value is greater than or equal to the second temperature threshold, it is determined that the corresponding glass partition 601 has a fogging risk.

[0098] In the embodiment of the present invention, the first temperature interval may be between 3 degrees Celsius and 5 degrees Celsius. That is, the dew point temperature may be 3 degrees Celsius to 5 degrees Celsius higher than the first temperature value. The second temperature threshold is used to ensure the lower limit of the internal and external temperature difference at which the glass partition 601 is prone to fogging. For example, the second temperature threshold may be 10 degrees Celsius, so that when the temperature difference between the second temperature value and the first temperature value of the corresponding glass partition 601 is greater than or equal to the second temperature threshold, it can be determined that the temperature of the inner surface of the glass of the corresponding glass partition 601 is much lower than the temperature of the outer surface of the glass of the glass partition 601. Thus, the temperature difference between the dew point temperature and the first temperature value of the glass partition 601 is within the first temperature interval, and it is determined that the temperature of the outer surface of the glass of the glass partition 601 is higher, and the difference with the temperature of the inner surface of the glass of the glass partition 601 is large, so that it can be determined that the corresponding glass partition 601 has a risk of fogging.

[0099] In other implementations, when the second humidity value of the glass partition 601 is greater than or equal to the first humidity threshold, it is determined that the corresponding glass partition 601 has a fogging risk.

[0100] In the embodiment of the present invention, the first humidity threshold is used to characterize the critical humidity threshold at which fog may appear on the surface of the glass partition 601. For example, the first humidity threshold may be 60%. When the humidity of the inner surface of the glass of the glass partition 601 exceeds or is equal to the first humidity threshold, the possibility of fog appearing on the glass surface increases. Therefore, when the second humidity value of the glass partition 601 is greater than or equal to the first humidity threshold, it is determined that the humidity of the inner surface of the glass of the glass partition 601 is too high, and the corresponding glass partition 601 has a risk of fogging.

[0101] In some further embodiments, when the humidity rising rate of the first humidity value of the glass partition 601 is greater than or equal to the first rising rate, it is determined that the corresponding glass partition 601 has a fogging risk.

[0102] In the embodiment of the present invention, considering that the humidity value of the glass inner surface of the glass partition 601 rises rapidly in a short time, even if the temperature of the glass inner surface of the glass partition 601 is stable, the risk of fogging will increase with the rapid increase of humidity. Therefore, the humidity rising rate of the first humidity value within 1 hour can be calculated based on the two first humidity values ​​detected per hour. The first rising rate can be understood as the lower limit of the rising rate of the humidity rising rate of the glass inner surface of the glass partition 601 that causes glass fogging. For example, the first rising rate is 20%. If the first humidity value of the glass inner surface of the glass partition 601 rises from 50% to 70% or from 50% to more than 70% within 1 hour, it can be determined that the humidity rising rate of the first humidity value of the glass partition 601 is greater than or equal to the first rising rate. It is determined that the first humidity value rises too fast in a short time, and it is determined that the corresponding glass partition 601 has a risk of fogging.

[0103] When the glass partition 601 does not have any of the above-mentioned fogging risks, the fogging risk result of the corresponding glass partition 601 is determined to be no fogging risk.

[0104] S304 , determining the frost risk result of each glass partition 601 according to the second temperature and humidity data of each glass partition 601 .

[0105] In the embodiment of the present invention, the glass door body 6 is prone to frost when the air humidity is high or the temperature is below 0 degrees Celsius. Therefore, a third temperature threshold can be preset, wherein the third temperature threshold is used to determine that the temperature value is lower than 0 degrees Celsius and the critical temperature value at which frost is likely to occur. For example, the third temperature threshold can be -1 degrees Celsius, or -2 degrees Celsius, or -3 degrees Celsius, etc. Therefore, when it is determined that the second temperature value of the glass partition 601 is less than the third temperature threshold, it is determined that the corresponding glass partition 601 has a risk of frost.

[0106] In another implementation, when the second humidity value of the glass partition 601 is greater than or equal to the second humidity threshold, it is determined that the corresponding glass partition 601 has a risk of frost.

[0107] In the embodiment of the present invention, the second humidity threshold is used to characterize the critical humidity threshold at which frost may appear on the surface of the glass partition 601. For example, the second humidity threshold may be 85%. When the humidity of the inner surface of the glass of the glass partition 601 exceeds or is equal to the first humidity threshold, the possibility of fog appearing on the glass surface increases. Therefore, when the second humidity value of the glass partition 601 is greater than or equal to the second humidity threshold, it is determined that the humidity of the inner surface of the glass of the glass partition 601 is too high, and the corresponding glass partition 601 has a risk of frost.

[0108] In yet another embodiment, when the humidity rising rate of the second humidity value of the glass partition 601 is greater than or equal to the second rising rate, it is determined that the corresponding glass partition 601 has a risk of frost.

[0109] In the embodiment of the present invention, considering that the humidity value of the glass inner surface of the glass partition 601 increases rapidly in a short period of time, even if the temperature of the glass inner surface of the glass partition 601 is lower than the temperature of the glass outer surface, the glass inner surface of the glass partition 601 will increase the risk of frost as the humidity increases rapidly. Therefore, the humidity rising rate of the second humidity value within 1 hour can be calculated based on the two second humidity values ​​detected per hour. The second rising rate can be understood as the lower limit of the rising rate of the humidity rising rate of the glass inner surface of the glass partition 601 that causes glass frost. For example, the second rising rate is 20%. If the second humidity value of the glass inner surface of the glass partition 601 increases from 60% to 80% or from 60% to more than 80% within 1 hour, it can be determined that the humidity rising rate of the second humidity value of the glass partition 601 is greater than or equal to the second rising rate. It is determined that the second humidity value rises too fast in a short period of time, and it is determined that the corresponding glass partition 601 has a risk of frost.

[0110] When the glass partition 601 does not have any of the above-mentioned frost risks, the frost risk result of the corresponding glass partition 601 is determined to be no frost risk.

[0111] In summary, when there is no frost risk and no fog risk in the same glass partition 601, its corresponding fogging and frost risk result is no fogging and frost risk. Therefore, the fogging and frost risk result can include at least the following three situations: fogging risk exists, frost risk exists, and no fogging and frost risk exists.

[0112] S305 , determining a heating strategy of the associated infrared heater 1 according to the fogging and frost risk results of each glass partition 601 .

[0113] In the embodiment of the present invention, after the fogging and frosting risk result is determined, a heating strategy of the infrared heater 1 associated with the glass partition 601 corresponding to the fogging and frosting risk result can also be matched. In one example, when it is determined that the corresponding glass partition 601 has a fogging risk, a heating strategy corresponding to the glass partition 601 having a fogging risk can be matched. This heating strategy is used as the heating strategy of the infrared heater 1 that heats the corresponding glass partition 601.

[0114] In another example, when it is determined that the corresponding glass partition 601 has a risk of frost formation, a heating strategy corresponding to the glass partition 601 having a risk of frost formation may be matched, and this heating strategy is used as a heating strategy for the infrared heater 1 that heats the corresponding glass partition 601 .

[0115] By analogy, according to the fogging and frost risk results of each glass partition 601 , the heating strategies of the infrared heaters 1 associated with each glass partition 601 are determined respectively.

[0116] For example, when it is determined that the glass partition 601 has no risk of fogging or frosting, it can be determined that the heating strategy corresponding to the risk of fogging or frosting is to stop the operation of the infrared heater 1. For another example, when it is determined that the glass partition 601 has a risk of fogging, it can be determined that the heating strategy corresponding to the risk of fogging is to determine that the infrared heater 1 of the corresponding glass partition 601 is heated according to a preset defrosting power. For another example, when it is determined that the glass partition 601 has a risk of frosting, it can be determined that the heating strategy corresponding to the risk of frosting is to determine that the infrared heater 1 of the corresponding glass partition 601 is heated according to a preset defrosting power.

[0117] The preset defrosting power can be determined according to the heating test results. For example, the temperature and humidity distribution inside and outside the glass door body 6 can be simulated in advance according to the temperature and humidity values ​​corresponding to the above-mentioned risk of frosting, and the temperature and humidity values ​​inside and outside can be adjusted so that the surface of the glass door body 6 is in a frosting state, and the first temperature and humidity data and the second temperature and humidity data are recorded at this time. Then the infrared heater 1 is started for heating, and the frost on the surface of the glass door body 6 is observed to gradually disappear during the heating process, and the first temperature and humidity data and the second temperature and humidity data after the frosting state completely disappears are recorded. Repeated tests are performed, such as increasing or decreasing the heating power of the infrared heater 1, shortening or extending the heating time of the infrared heater 1, etc. Thus, the optimal defrosting efficiency is determined according to multiple groups of test results, and used as the preset defrosting efficiency. Among them, the optimal defrosting efficiency can be that when the time does not exceed the preset heating time, the corresponding heating energy consumption is minimized, so that on the basis of ensuring high defrosting efficiency, the heat of thermal radiation is also taken into account, and energy consumption can be saved. Those skilled in the art can determine the corresponding preset heating time according to actual design requirements. For example, the preset heating time can be 30S (seconds), 45S, and 60S, etc., and no further limitations are given here.

[0118] In an optional embodiment of the invention, the method may further include correcting the preset defrost power based on the first temperature and humidity data and the second temperature and humidity data.

[0119] In an embodiment of the present invention, considering that when the risk of frost is detected in the glass partition 601, the corresponding second temperature value may be much lower than the third temperature threshold, and therefore, the glass partition 601 needs to be quickly heated and defrosted, the temperature and humidity correction coefficient can be determined based on the first temperature and humidity data and the second temperature and humidity data. And based on the temperature and humidity correction coefficient, the preset defrost power is corrected. For example, the temperature and humidity correction coefficient may include a temperature correction coefficient and a humidity correction coefficient. The second temperature value is negatively correlated with the temperature correction coefficient. In other words, the lower the second temperature value, the larger the corresponding temperature correction coefficient. For example, when the second temperature value is lower than the third temperature threshold, the ratio of the second temperature value to the third temperature threshold decreases by 5%, and the corresponding temperature correction coefficient increases by 10%.

[0120] In another example, the lower the second temperature value, the larger the corresponding temperature correction coefficient. The longer the heating time. For example, when the second temperature value is lower than the third temperature threshold, the ratio of the second temperature value to the third temperature threshold decreases by 5%, the corresponding temperature correction coefficient increases by 10%, and the corresponding heating time increases by 20%.

[0121] The second humidity value is positively correlated with the humidity correction coefficient. In other words, the higher the second humidity value, the larger the corresponding humidity correction coefficient. For example, when the second humidity value is greater than the second humidity threshold, the ratio of the second humidity value to the second humidity threshold increases by 10% for every 10% increase, and the corresponding humidity correction coefficient increases by 10%. Alternatively, the higher the second humidity value, the larger the corresponding humidity correction coefficient, and the longer the corresponding heating time. For example, when the second humidity value is greater than the second humidity threshold, the ratio of the second humidity value to the second humidity threshold increases by 10% for every 10% increase, and the corresponding heating time increases by 10%.

[0122] In summary, the temperature correction coefficient and / or humidity correction coefficient can be selected to correct (update) the preset defrost power. For example, when the temperature correction coefficient is 1.1, the corresponding corrected preset defrost power is 1.1 times the original value. When the temperature correction coefficient and humidity correction coefficient are selected to comprehensively correct the preset defrost power, the corrected preset defrost power is the product of the temperature correction coefficient, the humidity correction coefficient and the preset defrost power.

[0123] Taking into account the glass differences and environmental differences between the glass door bodies 6 of the test data and the actual different refrigeration equipment, the method can also correct the preset defrost power according to the glass correction coefficient, wind speed correction coefficient and light correction coefficient after determining the temperature and humidity correction coefficient. The glass correction coefficient can be determined based on factors such as the material of the glass door body 6 of the refrigeration equipment, the glass thickness and whether the glass surface is coated, and it can be a pre-stored setting. Compared with the glass door body 6 during the test, the more infrared absorption and reflection, the smaller the corresponding glass correction coefficient.

[0124] The wind speed correction factor is mainly used to compensate for the power loss of the infrared heater 1 caused by the different wind speeds when the refrigeration equipment is installed outdoors or indoors. It can be determined by the operation and maintenance personnel based on the wind speed in the environment where the refrigeration equipment is placed. For example, when the ambient wind speed is greater than the wind speed during the test and is 1.2 times, the wind speed correction factor can be determined to be 1.2. The faster the wind speed, the faster the heat dissipation of the glass door body 6, and the need to increase the heating power of the infrared heater 1.

[0125] The illumination correction factor is used to compensate for the signal interference of the illumination intensity on the infrared heater 1. For example, the ambient illumination may interfere with the signal reception of the infrared heater 1. When the signal interference of the ambient illumination intensity on the infrared heater 1 is greater than the signal interference of the illumination intensity on the infrared heater 1 during the test, the corresponding illumination correction factor is smaller, so that the influence of the illumination interference on the infrared signal reception can be reduced by reducing the heating power of the infrared heater 1.

[0126] In summary, after comprehensively correcting the preset defrost power according to the temperature correction coefficient and the humidity correction coefficient, the preset defrost power after the first correction can be obtained. Then, according to the product of the glass correction coefficient, the wind speed correction coefficient, the light correction coefficient and the preset defrost power after the first correction, the preset defrost power after the second correction can be obtained.

[0127] In other embodiments, the preset defogger power can be determined based on the heating test results. For example, the temperature and humidity distribution inside and outside the glass door body 6 can be simulated in advance according to the temperature and humidity values ​​corresponding to the above-mentioned risk of fogging, and the temperature and humidity values ​​inside and outside can be adjusted so that the surface of the glass door body 6 is in a fogging state, and the first temperature and humidity data and the second temperature and humidity data are recorded at this time. Then the infrared heater 1 is started for heating, and the fog on the surface of the glass door body 6 is observed to gradually disappear during the heating process, and the first temperature and humidity data and the second temperature and humidity data after the fogging state completely disappears are recorded. Repeated tests are performed, such as increasing or decreasing the heating power of the infrared heater 1, shortening or extending the heating time of the infrared heater 1, etc. Thus, the optimal defogger efficiency is determined based on multiple groups of test results, and used as the preset defogger efficiency. Among them, the optimal defogger efficiency can be that when the duration does not exceed the preset heating duration, the corresponding heating energy consumption is minimized, so that on the basis of ensuring high defogger efficiency, the heat of thermal radiation is also taken into account, and energy consumption can be saved. Those skilled in the art can determine the corresponding preset heating time according to actual design requirements. For example, the preset heating time can be 30S (seconds), 45S, and 60S, etc., and no further limitations are given here.

[0128] In an optional embodiment of the invention, the method may further include determining a temperature and humidity correction coefficient based on the first temperature and humidity data and the second temperature and humidity data, and correcting the preset defogger power based on the temperature and humidity correction coefficient.

[0129] In an embodiment of the present invention, it is considered that when the glass partition 601 is detected to have a risk of fogging, the temperature difference between the corresponding second temperature value and the first temperature value may be much greater than the second temperature threshold. Therefore, it is necessary to quickly heat and defog the glass partition 601, and the temperature and humidity correction coefficient can be determined based on the first temperature and humidity data and the second temperature and humidity data. And according to the temperature and humidity correction coefficient, the preset defog power is corrected. For example, the temperature and humidity correction coefficient may include a temperature correction coefficient and a humidity correction coefficient. The temperature difference between the second temperature value and the first temperature value is positively correlated with the temperature correction coefficient. In other words, the greater the temperature difference between the second temperature value and the first temperature value, the greater the corresponding temperature correction coefficient. For example, the ratio of the temperature difference between the second temperature value and the first temperature value to the second temperature threshold, for every 5% decrease, the corresponding temperature correction coefficient increases by 10%.

[0130] In another example, the greater the temperature difference between the second temperature value and the first temperature value, the greater the corresponding temperature correction coefficient and the longer the heating time. For example, for every 5% decrease in the ratio of the temperature difference between the second temperature value and the first temperature value to the second temperature threshold, the corresponding temperature correction coefficient increases by 10%. The corresponding heating time increases by 20%.

[0131] The second humidity value is positively correlated with the humidity correction coefficient. In other words, the higher the second humidity value is, the larger the corresponding humidity correction coefficient is. For example, when the second humidity value is greater than the first humidity threshold, the ratio of the second humidity value to the first humidity threshold increases by 10% for every 10% increase, and the corresponding humidity correction coefficient increases by 10%. Alternatively, the higher the second humidity value is, the larger the corresponding humidity correction coefficient is, and the corresponding heating time is longer. For example, when the second humidity value is greater than the first humidity threshold, the ratio of the second humidity value to the first humidity threshold increases by 10% for every 10% increase, and the corresponding humidity correction coefficient increases by 10%, and the corresponding heating time increases by 10%.

[0132] In summary, the temperature correction coefficient and / or humidity correction coefficient can be selected to correct (update) the preset defogger power. For example, when the temperature correction coefficient is 1.1, the corresponding corrected preset defogger power is 1.1 times the original value. When the temperature correction coefficient and humidity correction coefficient are selected to comprehensively correct the preset defogger power, the corrected preset defogger power is the product of the temperature correction coefficient, the humidity correction coefficient and the preset defogger power.

[0133] In some optional implementations, the preset defogger power may be corrected according to the temperature and humidity correction coefficient, the glass correction coefficient, the wind speed correction coefficient, and the light correction coefficient. The correction content of the preset defogger power refers to the correction content of the preset defrost power mentioned above.

[0134] Based on the above logic, the heating strategies associated with each glass partition 601 are determined respectively. For example, when it is determined that the glass partition 601 has no risk of fogging and frosting, it can be determined that the heating strategy corresponding to the risk of fogging and frosting is to stop the operation of the infrared heater 1. For another example, when it is determined that the glass partition 601 has a risk of fogging, it can be determined that the heating strategy corresponding to the risk of fogging is to determine the infrared heater 1 of the corresponding glass partition 601 to heat according to the revised preset defogger power. Or it can be heated according to the revised preset defogger power and the revised heating time.

[0135] For another example, when it is determined that the glass partition 601 has a risk of frost, the heating strategy corresponding to the risk of frost may be to determine that the infrared heater 1 corresponding to the glass partition 601 is heated according to the revised preset defrost power, or to heat according to the revised preset defrost power and the revised heating time.

[0136] S306 , driving the infrared heaters 1 associated with each glass partition 601 to operate according to the heating strategy.

[0137] In the embodiment of the present invention, the controller 5 drives the infrared heater 1 associated with each glass partition 601 to operate according to the corresponding heating strategy, so as to accurately control the heating power or heating time of each glass partition 601 to achieve a more efficient and uniform defrosting effect.

[0138] In some optional embodiments, during the process of the infrared heater 1 of the glass partition 601 heating according to the preset defrosting power, after a period of time (or a heating time), the first temperature and humidity data and the second temperature and humidity data of the corresponding glass partition 601 are obtained. Based on the first temperature and humidity data and the second temperature and humidity data, for example, the above-mentioned frost risk determination step is re-executed. When it is determined that the glass partition 601 has no frost risk, the operation of the associated infrared heater is stopped.

[0139] In some other optional embodiments, during the heating of the infrared heater 1 of the glass partition 601 according to the preset defogger power, after a period of time (or a heating time), the first temperature and humidity data and the second temperature and humidity data of the corresponding glass partition 601 are obtained. If, based on the first temperature and humidity data and the second temperature and humidity data, for example, the above-mentioned fogging risk determination step is re-executed, and it is determined that the glass partition 601 has no fogging risk, the operation of the associated infrared heater 1 is stopped.

[0140] In summary, the embodiment of the present invention discloses a control method for a glass heating device, which may include first obtaining the first temperature and humidity data of all glass partitions 601 of the glass door body 6, the second temperature and humidity data of all glass partitions 601, and the ambient temperature and humidity data. Then, based on the first temperature and humidity data of each glass partition 601, the second temperature and humidity data of each glass partition 601, and the ambient temperature and humidity data, the fogging and frosting risk results of each glass partition 601 are determined. Finally, based on the fogging and frosting risk results of each glass partition 601, the heating strategy of the associated infrared heater 1 is determined. And the infrared heater 1 associated with each glass partition 601 is driven to operate according to the heating strategy. In this way, the glass door body 6 can be divided into regions, and the infrared heater 1 can be used to heat the glass partition 601 that needs to be defogged and defrosted, thereby improving the uniformity and efficiency of defogger and defrost, and avoiding energy waste.
