Description

Technical Field

[0001] This application relates to the field of refrigerator control, and in particular to control methods, devices, refrigerators and storage media for preventing condensation in refrigerators. Background Technology

[0002] For refrigerators, when the temperature and humidity of the environment are high, reaching the dew point, the large temperature difference between the internal compartments and the external environment, coupled with the poor insulation of the refrigerator door, causes water vapor in the air to condense on the door surface, forming water droplets or mist, thus creating condensation. This phenomenon is particularly common on the freezer door surface.

[0003] Therefore, related technologies often improve the insulation effect of the refrigerator door by thickening the door or by attaching a vacuum insulation panel (VIP) inside the door to prevent excessive temperature differences between the refrigerator surface and the environment. However, thickening the door and using VIP panels increases manufacturing costs and reduces the effectiveness of preventing condensation on the door surface.

[0004] There is currently no effective solution to the problem that anti-condensation technology increases the manufacturing cost of refrigerators and has poor anti-condensation effect. Summary of the Invention

[0005] This embodiment provides a control method, device, refrigerator, and storage medium for preventing condensation in a refrigerator, in order to solve the problem in the related art that the prevention of condensation leads to increased manufacturing costs and poor condensation prevention effect.

[0007] Obtain the current ambient humidity within the space where the refrigerator is located;

[0008] When the current ambient humidity reaches a preset condensation humidity threshold, the surface temperature of the refrigerator door and the current ambient temperature of the space where the refrigerator is located are obtained.

[0009] Based on the difference between the door surface temperature and the current ambient temperature, and combined with the current ambient humidity, if the refrigerator is determined to meet the anti-condensation conditions, the electric heating component inside the door is controlled to operate until the difference between the door surface temperature and the current ambient temperature meets the preset heating stop condition.

[0010] In some embodiments, determining whether the refrigerator meets the anti-condensation conditions based on the difference between the door surface temperature and the current ambient temperature, combined with the current ambient humidity, includes:

[0012] When it is determined that the current ambient temperature is within the target ambient temperature range, a target temperature difference threshold corresponding to the target ambient temperature range is determined according to the target ambient temperature range and the second mapping relationship between the preset ambient temperature range and the temperature difference threshold.

[0013] When the difference between the door surface temperature and the current ambient temperature exceeds the target temperature difference threshold, the refrigerator is determined to have met the anti-condensation condition.

[0014] In some embodiments, in the first mapping relationship, the ambient temperature ranges corresponding to different ambient humidity are different; in the second mapping relationship, the temperature difference thresholds corresponding to different ambient temperature ranges are different.

[0015] In some embodiments, a target ambient temperature range corresponding to the current ambient humidity is determined based on the current ambient humidity and a preset mapping relationship between ambient humidity and ambient temperature ranges, including:

[0017] When the current ambient humidity is in the second humidity range, according to the first mapping relationship, the second ambient temperature range corresponding to the second humidity range is taken as the target ambient temperature range; the second ambient temperature range includes several sub-ranges, and the temperature difference thresholds corresponding to each sub-range of the second ambient temperature range are different;

[0018] When the current ambient humidity is in the third humidity range, according to the first mapping relationship, the third ambient temperature range corresponding to the third humidity range is taken as the target ambient temperature range; the third ambient temperature range includes several sub-ranges, and the temperature difference thresholds corresponding to each sub-range of the third ambient temperature range are different;

[0019] Each humidity value in the first humidity range is less than each humidity value in the second humidity range, and each humidity value in the second humidity range is less than each humidity value in the third humidity range.

[0020] In some embodiments, the preset heating stop condition includes: the difference between the door surface temperature and the current ambient temperature is below a preset difference threshold.

[0021] In some embodiments, the method further includes:

[0022] If the current ambient humidity does not reach the preset condensation humidity threshold, the electric heating component is kept off.

[0023] Secondly, this embodiment provides a control device for preventing condensation in a refrigerator, comprising: a first acquisition module, a second acquisition module, and a control module; wherein:

[0024] The first acquisition module is used to acquire the current ambient humidity in the space where the refrigerator is located;

[0025] The second acquisition module is used to acquire the surface temperature of the refrigerator door and the current ambient temperature in the space where the refrigerator is located when the current ambient humidity reaches a preset condensation humidity threshold.

[0026] The control module is used to control the operation of the electric heating component inside the door when the refrigerator reaches the anti-condensation condition based on the difference between the door surface temperature and the current ambient temperature, combined with the current ambient humidity, until the difference between the door surface temperature and the current ambient temperature meets the preset stop heating condition.

[0027] Thirdly, this embodiment provides a refrigerator, including: a cabinet, a door, a first temperature sensor, a second temperature sensor, a humidity sensor, an electric heating element, and a controller; the first temperature sensor is disposed on the surface of the door; the second temperature sensor is disposed on the refrigerator; the humidity sensor is disposed on the refrigerator; and the electric heating element is installed inside the door.

[0028] The first temperature sensor is used to collect the surface temperature of the door body;

[0029] The second temperature sensor is used to collect the current ambient temperature of the space where the refrigerator is located;

[0030] The humidity sensor is used to collect the current ambient humidity in the space where the refrigerator is located;

[0031] The controller is used to perform the control method for preventing condensation in a refrigerator as described in the first aspect above.

[0032] Fourthly, this embodiment provides an electronic device including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the anti-condensation control method for a refrigerator described in the first aspect above.

[0033] Fifthly, this embodiment provides a storage medium storing a computer program that, when executed by a processor, implements the control method for preventing condensation in a refrigerator as described in the first aspect above.

[0034] Compared with related technologies, this embodiment provides a control method, device, refrigerator, and storage medium for preventing condensation in a refrigerator. The control method for preventing condensation in a refrigerator involves acquiring the current ambient humidity within the space where the refrigerator is located; when the current ambient humidity reaches a preset condensation humidity threshold, acquiring the refrigerator door surface temperature and the current ambient temperature within the refrigerator space; and, based on the difference between the door surface temperature and the current ambient temperature, combined with the current ambient humidity, determining that the refrigerator meets the anti-condensation conditions, controlling the operation of the electric heating component inside the door until the difference between the door surface temperature and the current ambient temperature meets a preset stop heating condition. By combining ambient humidity, ambient temperature, and door surface temperature, it achieves accurate judgment of the anti-condensation timing and provides timely anti-condensation control through the electric heating component inside the door, thereby reducing manufacturing costs and improving the anti-condensation effect on the door surface.

[0047] This embodiment provides a method for preventing condensation in a refrigerator. Figure 2 This is a flowchart of the control method for preventing condensation in a refrigerator according to this embodiment, as follows: Figure 2 As shown, the process includes the following steps:

[0048] Step S210: Obtain the current ambient humidity in the space where the refrigerator is located.

[0049] Specifically, a humidity sensor can be installed on the outside of the refrigerator to collect the current ambient humidity of the space where the refrigerator is located. For example, the humidity sensor can be placed near the refrigerator door. The humidity sensor described above can be a sensor capable of sensing the water vapor content in the gas and converting it into a usable output signal. This embodiment does not specifically limit the type or model of the humidity sensor used.

[0050] Step S220: When the current ambient humidity reaches the preset condensation humidity threshold, obtain the surface temperature of the refrigerator door and the current ambient temperature of the space where the refrigerator is located.

[0051] Condensation on the refrigerator door surface occurs under high humidity conditions. When the humidity in the environment where the refrigerator is located reaches a certain level, there is a risk of condensation on the refrigerator door surface. Therefore, the current humidity of the space where the refrigerator is located can be monitored in real time. When the current humidity exceeds a certain value, a condensation prevention logic can be implemented. Specifically, the aforementioned condensation humidity threshold can be 75%, meaning that the refrigerator's anti-condensation logic is activated when the current humidity exceeds 75%. Understandably, other values ​​can also be set as the condensation humidity threshold according to the actual application scenario and user needs; this embodiment does not specifically limit this.

[0052] Since the significant temperature difference between the refrigerator door and the ambient temperature is a factor contributing to condensation on the door surface, the determination of whether condensation prevention is necessary first involves obtaining the surface temperature of the refrigerator door and the current ambient temperature of the space surrounding the refrigerator. This can be achieved using a first temperature sensor mounted on the refrigerator door surface and a second temperature sensor located outside the refrigerator to collect the current ambient temperature. The placement of the second temperature sensor is not specifically limited in this embodiment, as long as it accurately captures the current ambient temperature. Both the first and second temperature sensors can be sensors capable of sensing temperature and converting it into a usable output signal. Any temperature sensor suitable for measuring the refrigerator door and interior temperature can be used; this embodiment does not limit the specific type or model of the sensor used.

[0053] Step S230: Based on the difference between the door surface temperature and the current ambient temperature, and combined with the current ambient humidity, if the refrigerator meets the anti-condensation conditions, control the operation of the electric heating component inside the door until the difference between the door surface temperature and the current ambient temperature meets the preset stop heating condition.

[0054] After collecting the door surface temperature and the current ambient temperature, the difference between the two is calculated. Understandably, before implementing anti-condensation measures, the door surface temperature is lower than the current ambient temperature. However, after implementing anti-condensation measures, the door surface temperature can rise above the current ambient temperature due to the continuous heating process of the electric heating element. This difference, combined with the current ambient humidity, is used to determine whether the refrigerator meets the anti-condensation conditions. Specifically, these anti-condensation conditions determine whether anti-condensation control of the refrigerator is necessary. Once it is determined that the refrigerator meets the anti-condensation conditions, the electric heating element inside the door can be controlled to heat the door, thereby reducing the difference between the door surface temperature and the current ambient temperature. This electric heating element can specifically be an electric heating coil installed inside the door.

[0055] Specifically, if the current ambient humidity exceeds a preset condensation humidity threshold, and the temperature difference between the door surface and the current ambient temperature also reaches a corresponding temperature difference threshold, the refrigerator can confirm that it has met the anti-condensation conditions. In this case, the electric heating coil can be activated to heat the refrigerator door. More specifically, different temperature ranges can be set for different humidity ranges of the current ambient humidity. When the current ambient temperature falls within the temperature range corresponding to the current ambient humidity, it is further determined whether the aforementioned difference exceeds the temperature difference threshold corresponding to that temperature range. If so, the refrigerator is confirmed to have met the preset anti-condensation conditions, and the electric heating coil is controlled to heat the door.

[0056] To prevent overheating of the door and affecting the refrigerator's internal cooling performance, the door surface temperature and the current ambient temperature are monitored in real time during the operation of the electric heating element. When the difference between the door surface temperature and the current ambient temperature is detected to be lower than a preset threshold, the electric heating element is stopped. For example, the electric heating element will stop operating when the door surface temperature is the same as the current ambient temperature, or when the door surface temperature is 1°C higher than the current ambient temperature.

[0057] In related technologies, to prevent condensation on the refrigerator door surface, the door is often thickened or a VIP panel is pasted inside to improve its insulation and prevent excessive temperature differences between the refrigerator surface and the environment. However, thickening the door and using VIP panels increases manufacturing costs and results in poorer condensation prevention.

[0058] To address this, this embodiment, through steps S210 to S230, achieves accurate anti-condensation judgment based on the detection of the difference between the door surface temperature and the current ambient temperature, combined with the detection of the current ambient humidity. By installing an electric heating component inside the door, when the refrigerator meets the anti-condensation conditions, the electric heating component is controlled to heat the door, thereby increasing the door surface temperature and reducing the difference between the door surface temperature and the current ambient temperature, thus achieving the purpose of preventing condensation. Compared with related technologies, the method adopted in this embodiment does not require thickening the door or pasting a VIP panel inside the door, thus reducing manufacturing costs while improving the anti-condensation effect on the door surface.

[0059] Steps S210 to S230 above involve acquiring the current ambient humidity within the refrigerator's space; if the current ambient humidity reaches a preset condensation humidity threshold, acquiring the refrigerator door surface temperature and the current ambient temperature within the refrigerator's space; and, based on the difference between the door surface temperature and the current ambient temperature, combined with the current ambient humidity, determining that the refrigerator meets the anti-condensation conditions, controlling the operation of the electric heating component inside the door until the difference between the door surface temperature and the current ambient temperature meets the preset stop heating condition. By combining ambient humidity, ambient temperature, and door surface temperature, accurate judgment of the anti-condensation timing is achieved, and timely anti-condensation control is implemented through the electric heating component inside the door, thereby reducing manufacturing costs and improving the anti-condensation effect on the door surface.

[0060] In one embodiment, based on step S230 above, determining whether the refrigerator has met the anti-condensation conditions based on the difference between the door surface temperature and the current ambient temperature, combined with the current ambient humidity, may include:

[0061] Based on the current ambient humidity and the first mapping relationship between the preset ambient humidity and ambient temperature range, the target ambient temperature range corresponding to the current ambient humidity is determined; when the current ambient temperature is determined to be within the target ambient temperature range, the target ambient temperature range is determined based on the second mapping relationship between the target ambient temperature range and the preset ambient temperature range and temperature difference threshold; when the difference between the door surface temperature and the current ambient temperature exceeds the target temperature difference threshold, the refrigerator is determined to have reached the anti-condensation condition.

[0062] This involves dividing the environment into multiple humidity ranges above the condensation humidity threshold, and corresponding to each humidity range, setting an ambient temperature range in advance based on empirical values ​​or simulation tests to form the aforementioned first mapping relationship. In other words, this first mapping relationship is pre-defined and represents the correspondence between different humidity ranges and ambient temperature ranges.

[0063] Furthermore, temperature difference thresholds can be set for different ambient temperature ranges to form the aforementioned second mapping relationship. That is, the aforementioned second mapping relationship is pre-defined and represents the correspondence between different ambient temperature ranges and temperature difference thresholds.

[0064] Therefore, when the current ambient humidity is detected to be higher than the condensation humidity threshold and within a certain humidity range, a target ambient temperature range corresponding to the current humidity range is determined from multiple ambient temperature ranges based on the first mapping relationship. It is then determined whether the current ambient temperature falls within this target ambient temperature range. If so, a target temperature difference threshold corresponding to the target ambient temperature range is determined from multiple temperature difference thresholds based on the second mapping relationship. Next, it is determined whether the difference between the door surface temperature and the current ambient temperature exceeds the target temperature difference threshold. If so, the refrigerator is confirmed to have met the anti-condensation conditions. At this point, there is a high probability of condensation appearing on the refrigerator door surface, therefore, timely anti-condensation measures are necessary.

[0065] In this embodiment, by setting the first mapping relationship and the second mapping relationship, more refined anti-condensation judgment can be achieved for different environmental humidity levels, thereby achieving accurate and timely anti-condensation control and improving the anti-condensation effect.

[0066] In one embodiment, in the first mapping relationship, the ambient temperature ranges corresponding to different ambient humidity are different; in the second mapping relationship, the temperature difference thresholds corresponding to different ambient temperature ranges are different.

[0067] More specifically, in one embodiment, a target ambient temperature range corresponding to the current ambient humidity is determined based on the current ambient humidity and a preset mapping relationship between ambient humidity and ambient temperature ranges. This may specifically include:

[0068] When the current ambient humidity is in the first humidity range, according to the first mapping relationship, the first ambient temperature range corresponding to the first humidity range is taken as the target ambient temperature range; the first ambient temperature range includes several sub-ranges, and the temperature difference thresholds corresponding to each sub-range of the first ambient temperature range are different; when the current ambient humidity is in the second humidity range, according to the first mapping relationship, the second ambient temperature range corresponding to the second humidity range is taken as the target ambient temperature range; the second ambient temperature range includes several sub-ranges, and the temperature difference thresholds corresponding to each sub-range of the second ambient temperature range are different; when the current ambient humidity is in the third humidity range, according to the first mapping relationship, the third ambient temperature range corresponding to the third humidity range is taken as the target ambient temperature range; the third ambient temperature range includes several sub-ranges, and the temperature difference thresholds corresponding to each sub-range of the third ambient temperature range are different; the humidity values ​​in the first humidity range are lower than the humidity values ​​in the second humidity range, and the humidity values ​​in the second humidity range are lower than the humidity values ​​in the third humidity range.

[0069] The current ambient humidity can be divided into three different humidity ranges: a first humidity range, a second humidity range, and a third humidity range. Understandably, the values ​​in all three humidity ranges are higher than the preset condensation humidity threshold. Specifically, the values ​​in the second humidity range are higher than those in the first humidity range, and the values ​​in the third humidity range are higher than those in the second range. Corresponding to each of the three humidity ranges, different ambient temperature ranges can be set. Each ambient temperature range can be further divided into more sub-ranges as needed, and corresponding temperature difference thresholds can be set for each sub-range.

[0070] For example, the first humidity range can be 75% to 85%. The corresponding ambient temperature range for the first humidity range can be divided into three sub-ranges: 10℃ to 19℃, 19℃ to 27℃, and 27℃ to 33℃. For each sub-range, a temperature difference threshold can be set to 4.4℃, 4.7℃, and 5.0℃, respectively. For instance, if the current ambient humidity is greater than or equal to 75% and less than 85%, it is confirmed that the current ambient humidity is within the first humidity range. If the current ambient temperature is greater than or equal to 10℃ and less than 19℃, it is determined whether the difference between the door surface temperature and the current ambient temperature is higher than 4.4℃. If so, it is confirmed that the refrigerator meets the anti-condensation conditions.

[0071] Accordingly, the second humidity range can be 85% to 95%. The corresponding ambient temperature range for this second humidity range can be divided into three sub-ranges: 10℃ to 24℃, 24℃ to 32℃, and 32℃ to 38℃. For each sub-range, a temperature difference threshold can be set to 2.6℃, 2.7℃, and 3.0℃, respectively. For example, if the current ambient humidity is greater than or equal to 85% and less than 95%, it is confirmed that the current ambient humidity is within the second humidity range. If the current ambient temperature is greater than or equal to 10℃ and less than 24℃, it is determined whether the difference between the door surface temperature and the current ambient temperature is higher than 2.6℃. If so, it is confirmed that the refrigerator meets the anti-condensation conditions.

[0072] For example, the third humidity range can be 95% or higher. The corresponding ambient temperature range for this third humidity range can be divided into two sub-ranges: 10℃ to 23℃ and 23℃ to 36℃. For each sub-range, a temperature difference threshold of 0.8℃ and 0.9℃ can be set. For instance, if the current ambient humidity is greater than or equal to 95%, it is confirmed that the current ambient humidity is within the third humidity range. If the current ambient temperature is greater than or equal to 10℃ but less than 23℃, it is determined whether the difference between the door surface temperature and the current ambient temperature is higher than 0.8℃. If so, the refrigerator is confirmed to meet the anti-condensation conditions.

[0073] In this embodiment, corresponding to different humidity ranges, more refined sub-ranges of ambient temperature are defined, and temperature difference thresholds are set for each sub-range. Therefore, this embodiment can achieve more targeted anti-condensation control for different ambient humidity and ambient temperature, thereby improving the anti-condensation effect.

[0074] Furthermore, in one embodiment, the preset heating stop condition includes: the difference between the door surface temperature and the current ambient temperature is below a preset difference threshold. For example, the heating stop condition is confirmed to be met when the door surface temperature is the same as the current ambient temperature, or when the door surface temperature is 1°C higher than the current ambient temperature.

[0075] In another embodiment, the control method may further include: keeping the electric heating element off when the current ambient humidity does not reach a preset condensation humidity threshold. In this embodiment, after successful anti-condensation control, the electric heating element is turned off promptly to avoid affecting the refrigeration performance inside the refrigerator and to reduce the refrigerator's power consumption.

[0076] Figure 3 These are flowcharts of some embodiments of a control method for preventing condensation in a refrigerator, such as... Figure 3 As shown, the control method includes the following steps:

[0077] Step S301: Turn off the electric heating coil located inside the refrigerator door.

[0078] Step S302: Determine whether the current ambient humidity in the space where the refrigerator is located is greater than or equal to 75%; if the current ambient humidity is greater than or equal to 75% and less than 85%, proceed to step S303; if the current ambient humidity is greater than or equal to 85% and less than 95%, proceed to step S304; if the current ambient humidity is greater than or equal to 95%, proceed to step S305; it can also be understood that if the current ambient humidity is less than 75%, return to proceed to step S301 (indicator lines are not shown in the figure).

[0079] Step S303: Determine whether the current ambient temperature is greater than or equal to 10℃; if the current ambient temperature is greater than or equal to 10℃ and less than 19℃, proceed to step S306; if the current ambient temperature is greater than or equal to 19℃ and less than 27℃, proceed to step S307; if the current ambient temperature is greater than or equal to 27℃ and less than 33℃, proceed to step S308.

[0080] Step S304: Determine whether the current ambient temperature is greater than or equal to 10℃; if the current ambient temperature is greater than or equal to 10℃ and less than 24℃, proceed to step S309; ​​if the current ambient temperature is greater than or equal to 24℃ and less than 32℃, proceed to step S310; if the current ambient temperature is greater than or equal to 32℃ and less than 38℃, proceed to step S311.

[0081] Step S305: Determine whether the current ambient temperature is greater than or equal to 10℃; if the current ambient temperature is greater than or equal to 10℃ and less than 23℃, then proceed to step S312; if the current ambient temperature is greater than or equal to 23℃ and less than 36℃, then proceed to step S313.

[0082] Step S306: Determine whether the difference between the door surface temperature and the current ambient temperature is higher than 4.4℃; if so, proceed to step S314.

[0086] Step S310: Determine whether the difference between the door surface temperature and the current ambient temperature is higher than 2.8℃; if so, proceed to step S314.

[0087] Step S311: Determine whether the difference between the door surface temperature and the current ambient temperature is higher than 3.0℃; if so, proceed to step S314.

[0088] Step S312: Determine whether the difference between the door surface temperature and the current ambient temperature is higher than 0.8℃; if so, proceed to step S314.

[0091] Step S315: If the surface temperature of the door is 1°C higher than the current ambient temperature, return to step S301.

[0092] The steps S301 to S315 above, combined with ambient humidity, ambient temperature and door surface temperature, enable accurate judgment of the anti-condensation timing, and timely anti-condensation control is achieved through the electric heating components installed inside the door, thereby reducing manufacturing costs and improving the anti-condensation effect on the door surface.
