[0006] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0007] This disclosure provides a method, apparatus, indoor unit, and storage medium for preventing condensation in an air conditioner indoor unit, thereby suppressing the occurrence of condensation.

[0008] In some embodiments, the indoor unit of the air conditioner includes a housing with an air outlet, an indoor fan disposed within the housing, a heat exchange pipe filled with a heat exchange medium and arranged circumferentially along the air outlet, a heating component sleeved on a portion of the heat exchange pipe, and a power component disposed on the heat exchange pipe. The method includes: determining the indoor relative humidity when operating in cooling / dehumidification mode in summer; adjusting the indoor fan speed according to the indoor relative humidity; determining the temperature difference between the indoor temperature and the temperature of the housing around the air outlet; and controlling the heating component to heat the heat exchange medium and controlling the power component to drive the heated heat exchange medium to flow according to the temperature difference.

[0009] In some embodiments, the apparatus includes a processor and a memory storing program instructions, wherein the processor is configured to, when executing the program instructions, perform the aforementioned method for preventing condensation in an indoor air conditioning unit.

[0010] In some embodiments, the indoor unit of the air conditioner includes a housing with an air outlet and an indoor fan disposed within the housing, and further includes: a heat exchange pipe filled with a liquid heat exchange medium, at least a portion of which is disposed circumferentially along the air outlet on the inner sidewall of the housing facing the indoor fan; a heating assembly sleeved on a portion of the heat exchange pipe and configured to heat the heat exchange medium; a power assembly disposed on the heat exchange pipe and forming a circulation loop of the heat exchange medium with the heat exchange pipe, configured to drive the heated heat exchange medium to flow to achieve heat exchange with the housing surrounding the air outlet; and, as described above, a device for preventing condensation in the indoor unit of the air conditioner.

Therefore, based on the indoor relative humidity, it's determined whether condensation is likely at the air outlet of the indoor unit. If condensation is possible, the indoor fan speed is controlled to initially increase the outlet air temperature, thus preventing condensation. Simultaneously, based on the adjusted fan speed and the temperature difference between the indoor temperature and the surrounding casing temperature, the operation of the heating and power components is controlled to further prevent condensation from forming on the casing around the outlet. In this way, by adjusting the indoor fan speed and controlling the operation of the heating and power components in situations where condensation is likely, condensation formation is suppressed, improving the effectiveness of condensation prevention and preventing water spraying, thus enhancing user comfort when using the air conditioner.

[0031] In this embodiment of the disclosure, smart home appliances refer to home appliances formed by introducing microprocessors, sensor technology and network communication technology into home appliances. They have the characteristics of intelligent control, intelligent sensing and intelligent application. The operation of smart home appliances often relies on the application and processing of modern technologies such as the Internet of Things, the Internet and electronic chips. For example, smart home appliances can be connected to electronic devices to enable users to remotely control and manage smart home appliances.

[0032] Combination Figure 1 , 2As shown, this embodiment of the present disclosure provides an indoor air conditioning unit, including a housing 100 with an air outlet 110 and an indoor fan disposed within the housing 100, a heat exchange pipe 210, a heating component 220, and a power component 230. The heat exchange pipe 210 is filled with a liquid heat exchange medium, and at least a portion of the pipe section is disposed circumferentially along the air outlet 110 on the inner sidewall of the housing 100 facing the indoor fan. The heating component 220 is sleeved on the outside of a portion of the heat exchange pipe 210 and is configured to heat the heat exchange medium. The power component 230 is disposed on the heat exchange pipe 210 and forms a circulation loop for the heat exchange medium with the heat exchange pipe 210, and is configured to drive the heated heat exchange medium to flow to achieve heat exchange with the housing 100 surrounding the air outlet 110.

[0033] When the indoor unit of the air conditioner is running, that is, when the indoor unit is cooling for a long time or when the indoor unit is cooling in a high humidity environment, the airflow temperature at the air outlet 110 of the indoor unit is low. At this time, the heating component 220 and the power component 230 work simultaneously. The heating component 220 is used to heat the heat exchange medium inside the heat exchange pipe 210, and the power component 230 can drive the heated heat exchange medium to flow in the heat exchange pipe 210. During the flow of the heat exchange medium, a section of the heat exchange pipe 210 arranged circumferentially along the air outlet 110 exchanges heat with the shell 100 around the air outlet 110 to heat the shell 100 and reduce the temperature difference between the shell 100 and the indoor environment. This makes it difficult for the air near the air outlet 110 to condense water on the shell around the air outlet 110, thus preventing condensation from forming on the shell around the air outlet 110 of the indoor unit.

[0034] Optionally, the housing 100 is provided with an air outlet 110. Through the air outlet 110, the airflow after heat exchange inside the housing 100 of the air conditioner indoor unit can be blown into the room to regulate the indoor ambient temperature.

[0035] Optionally, the inner-facing casing around the air outlet 110 is in contact with the heat-exchanged gas flowing out of the evaporator of the indoor unit of the air conditioner. Therefore, its temperature is low and the temperature difference with the indoor environment outside the casing 100 is large. Condensation is more likely to occur when the indoor temperature is high. Therefore, the heat exchange pipe 210 is set on the inner side wall of the casing 100 around the air outlet 110 so as to heat the inner side wall of the casing 100 around the air outlet 110 through the heat exchange pipe 210, thereby avoiding condensation around the air outlet 110.

[0036] Optionally, the heating assembly 220 includes an electric heating wire wound around the outside of the heating section 212. This increases the contact area between the heating assembly and the surface of the heating section 212, facilitating heat transfer and thus improving the heating effect of the heating assembly 220 on the heat exchange medium flowing through the heating section 212.

[0037] Optionally, the heating wire is fixed to the outer surface of the heating section 212 by adhesive to improve the stability of the heating assembly 220. Optionally, the outer surface of the heating wire is wrapped with a layer of aluminum foil, that is, the aluminum foil is glued to the surface of the heating wire and the aluminum foil layer is glued to the surface of the heating section 212. This can prevent leakage of electricity from the heating assembly and improve the safety of the heating assembly 220.

[0038] Optionally, the heating assembly 220 includes a semiconductor temperature regulating element, comprising a first end and a second end. When the semiconductor temperature regulating element is cooling, the first end is the cold end and the second end is the hot end. The second end is mounted in contact with the surface of the heating section 212. The semiconductor heats up quickly, thus enabling rapid heating of the heat exchange medium flowing through the heating section 212.

[0039] Optionally, the power assembly 230 is disposed on the heat exchange pipe 210, including an input side and an output side, and can form a circulation loop of the heat exchange medium with the heat exchange pipe 210. The heating assembly 220 is disposed outside a portion of the heat exchange pipe 210 and located on the input side of the power assembly 230. Thus, when the heating assembly is operating, it can heat the heat exchange medium. The power assembly 230 can easily drive the heated heat exchange medium to move. When the medium flows through the housing 100 surrounding the air outlet 110, it exchanges heat with the housing 100 and then flows back to the portion of the heat exchange pipe 210 where the heating assembly 220 is located, repeating the cycle.

[0040] Alternatively, the heat exchange medium can be antifreeze or refrigerant.

[0041] Optionally, a first temperature sensor is provided on the inner wall of the housing 100 along the axial direction of the air outlet 110, near the air outlet, to detect the temperature of the housing around the air outlet. A second temperature sensor is provided on the outside of the housing 100, away from the air outlet, or at any location in the room, to detect the room temperature.

[0042] Combination Figure 3 As shown in the embodiments of this disclosure, a method for preventing condensation in an air conditioner indoor unit is provided, comprising:

[0043] S101, the processor determines the indoor relative humidity when running in cooling / dehumidification mode during the summer.

[0044] S102, the processor adjusts the indoor fan speed according to the indoor relative humidity.

[0045] S103, the processor determines the temperature difference between the indoor temperature and the surrounding housing temperature of the air outlet.

[0046] S104, the processor controls the heating component to heat the heat exchange medium and controls the power component to drive the flow of the heated heat exchange medium based on the indoor fan speed and temperature difference.

[0047] Users can control the air conditioner to switch between cooling and dehumidification modes using a remote control or smart terminal device (such as a mobile phone, iPad, etc.). When the indoor unit operates in cooling / dehumidification mode during summer, it determines the indoor relative humidity. This is because, in cooling or dehumidification mode, the indoor unit delivers low-temperature airflow into the room; if the indoor relative humidity is high, condensation may occur. The indoor fan speed is adjusted based on the indoor relative humidity. If the indoor relative humidity exceeds a preset value, the fan speed is increased to raise the outlet air temperature and reduce the likelihood of condensation. Optionally, a first temperature sensor is provided on the inner wall of the housing 100 along the axial direction of the outlet 110, near the outlet, to detect the temperature of the housing surrounding the outlet. A second temperature sensor is provided on the outside of the housing 100, away from the outlet, or at any location within the room, to detect the indoor temperature. The processor determines the temperature difference between the first and second temperature sensors, and controls the heating component to heat the heat exchange medium and the power component to drive the heated heat exchange medium to flow based on the temperature difference.

[0048] The method for preventing condensation in an air conditioner indoor unit provided in this disclosure relies on the fact that the rotational speed of the indoor fan affects the indoor ambient temperature and thus the formation of condensation. Therefore, based on the indoor relative humidity, it is determined whether condensation is likely at the air outlet of the indoor unit. If condensation is possible, the indoor fan speed is controlled to initially increase the outlet air temperature, thus preventing condensation. Furthermore, based on the adjusted fan speed and the temperature difference between the indoor temperature and the surrounding casing temperature at the air outlet, the operation of the heating and power components is controlled to further prevent condensation from forming on the casing around the air outlet. In this way, by adjusting the indoor fan speed and controlling the operation of the heating and power components when condensation is possible, the formation of condensation is suppressed, improving the effectiveness of condensation prevention and preventing water spraying, thereby improving user comfort when using the air conditioner.

[0049] Optionally, combined Figure 4As shown in the embodiments of this disclosure, another method for preventing condensation in air conditioners is provided, including:

[0050] S101, the processor determines the indoor relative humidity when running in cooling / dehumidification mode during the summer.

[0051] S112, when the relative humidity in the room is greater than the first humidity threshold and less than the second humidity threshold, the processor adjusts the speed of the indoor fan to the first speed.

[0052] S122, when the relative humidity in the room is greater than or equal to the second humidity threshold, the processor adjusts the speed of the indoor fan to the second speed.

[0053] S103, the processor determines the temperature difference between the indoor temperature and the surrounding housing temperature of the air outlet.

[0054] S104, the processor controls the heating component to heat the heat exchange medium and controls the power component to drive the flow of the heated heat exchange medium based on the indoor fan speed and temperature difference.

[0055] The first rotational speed is less than the second rotational speed.

[0056] Specifically, the first humidity threshold is 47%, and the second humidity threshold is 70%.

[0057] Optionally, the higher the indoor relative humidity, the greater the likelihood of condensation on the casing around the air outlet. In this solution, when the indoor relative humidity is greater than a first humidity threshold but less than a second humidity threshold, the indoor fan speed is increased to the first speed. Specifically, the fan speed before adjustment is V. 原 Then V 第一转速 =(V 原 +50*n)r / s, where n = 1, 2, 3, ... etc. When the indoor relative humidity is greater than or equal to the second humidity threshold, adjust the indoor fan speed to the second speed. Specifically, the fan speed before adjustment is V. 原 Then V 第二转速 =(V 原 +100*n)r / s, where n = 1, 2, 3, ... etc.

[0058] It should be noted that the specific implementation methods of steps S101, S103 and S104 can be found in the above embodiments, and will not be repeated here.

[0059] Optionally, combined Figure 5 As shown in the embodiments of this disclosure, another method for preventing condensation in air conditioners is provided, including:

[0060] S101, the processor determines the indoor relative humidity when running in cooling / dehumidification mode during the summer.

[0061] S102, the processor adjusts the indoor fan speed according to the indoor relative humidity.

[0062] S103, the processor determines the temperature difference between the indoor temperature and the surrounding housing temperature of the air outlet.

[0063] S114, when the indoor fan speed is increased to the first speed and the temperature difference is greater than the first preset difference and less than the second preset difference, the processor controls the heating component to operate at the first speed and controls the power component to operate at the low speed.

[0064] S124, when the indoor fan speed is increased to the first speed and the temperature difference is greater than or equal to the second preset difference, the processor controls the heating component to operate at the second level and controls the power component to operate at the high speed.

[0065] The first setting is the low temperature setting, and the second setting is the medium temperature setting.

[0066] After adjusting the indoor fan speed to a first speed, the difference between the detected indoor temperature and the casing temperature around the air outlet is determined. Optionally, a first temperature sensor is installed at the location on the casing around the air outlet where condensation is most likely to occur, and the detected temperature value is used as the determined casing temperature around the air outlet. Optionally, multiple first temperature sensors are installed around the air outlet to obtain multiple temperature values ​​of the casing around the air outlet, and the average of these multiple temperature values ​​is used as the determined casing temperature around the air outlet. Optionally, by adjusting the indoor fan speed, preliminary anti-condensation control of the air conditioner indoor unit can be performed. Further control is then performed after determining the difference between the indoor temperature and the casing temperature around the air outlet, which can improve the effectiveness of preventing condensation.

[0067] Optionally, in step S114, when the indoor relative humidity is greater than a first humidity threshold and less than a second humidity threshold, it indicates a risk of condensation, and the indoor fan speed is increased to the first speed. After the indoor fan speed is increased to the first speed, if the temperature difference between the indoor temperature and the temperature of the casing around the air outlet is greater than a first preset difference and less than a second preset difference, this temperature difference is low, indicating that simply increasing the indoor fan speed is not enough to effectively suppress condensation. At this point, there is still a risk of condensation, but the risk is not high. In this case, the heating component and the power component are controlled to operate. Specifically, the heating component is controlled to operate at the first setting, i.e., at a low temperature setting, to heat the heat exchange medium, and the power component is controlled to operate at a low speed setting to allow the heat exchange medium to flow and exchange heat with the casing around the air outlet, thereby preventing condensation.

[0068] Optionally, in step S124, when the indoor relative humidity is greater than a first humidity threshold but less than a second humidity threshold, it indicates a risk of condensation, and the indoor fan speed is increased to the first speed. After the indoor fan speed is increased to the first speed, if the indoor temperature and the temperature of the casing around the air outlet are greater than or equal to a second preset difference, and this temperature difference is large, it indicates an increased risk of condensation. At this time, the heating component and the power component are controlled to operate. Specifically, the heating component is controlled to operate at the second setting, i.e., at the medium temperature setting, to increase the heating temperature of the heat exchange medium, and the power component is controlled to operate at the high speed setting to increase the heat exchange between the heat exchange medium and the casing around the air outlet, thereby effectively preventing the generation of condensation.

[0069] In this way, when the indoor relative humidity is greater than a first humidity threshold but less than a second humidity threshold, the speed of the indoor fan is increased. By increasing the speed of the indoor fan, the outlet air temperature is increased, thereby reducing the probability of condensation. Simultaneously, when the difference between the indoor temperature and the temperature of the casing around the air outlet is greater than a first preset value but less than a second preset value, the heating component is controlled to operate at a low temperature setting and the power component is controlled to operate at a low speed setting; or, when the difference between the indoor temperature and the temperature of the casing around the air outlet is greater than or equal to the second preset value, the heating component is controlled to operate at a medium temperature setting and the power component is controlled to operate at a high speed setting. Through the above scheme, the heat exchange medium heats the casing around the air outlet, fundamentally preventing condensation. Thus, by controlling the heating component and power component in different ways, the temperature difference between the casing around the air outlet and the indoor temperature is reduced, thereby improving the effectiveness of preventing condensation.

[0070] It should be noted that the specific implementation methods of steps S101, S102 and S103 can be found in the above embodiments, and will not be repeated here.

[0071] Optionally, combined Figure 6 As shown in the embodiments of this disclosure, another method for preventing condensation in air conditioners is provided, including:

[0072] S101, the processor determines the indoor relative humidity when running in cooling / dehumidification mode during the summer.

[0073] S102, the processor adjusts the indoor fan speed according to the indoor relative humidity.

[0074] S103, the processor determines the temperature difference between the indoor temperature and the surrounding housing temperature of the air outlet.

[0075] S134, when the indoor fan speed is increased to the second speed and the temperature difference is greater than the first preset difference and less than the second preset difference, the processor controls the heating component to operate at the second speed and controls the power component to operate at the low speed.

[0076] S144, when the indoor fan speed is increased to the second speed and the temperature difference is greater than or equal to the second preset difference, the processor controls the heating component to operate at the third speed and controls the power component to operate at the high speed.

[0077] The second setting is the medium temperature setting, and the third setting is the high temperature setting.

[0078] After adjusting the indoor fan speed to the second speed, the difference between the detected indoor temperature and the casing temperature around the air outlet is determined. Optionally, a first temperature sensor is installed at the location on the casing around the air outlet where condensation is most likely to occur, and the detected temperature value is used as the determined casing temperature around the air outlet. Optionally, multiple first temperature sensors are arranged around the air outlet to obtain multiple temperature values ​​of the casing around the air outlet, and the average of the multiple temperature values ​​is calculated as the determined casing temperature around the air outlet.

[0079] Optionally, in step S134, if the indoor relative humidity is greater than or equal to the second humidity threshold, indicating a risk of condensation, the indoor fan speed is increased to the second speed. After the indoor fan speed is increased to the second speed, if the temperature difference between the indoor temperature and the temperature of the casing around the air outlet is greater than the first preset difference but less than the second preset difference, although the temperature difference is low, the indoor relative humidity is high, and simply increasing the indoor fan speed is not enough to effectively suppress condensation. Therefore, the risk of condensation is high. At this time, the heating component and the power component are controlled to operate. Specifically, the heating component is controlled to operate at the second setting, i.e., at the medium temperature setting, to heat the heat exchange medium, and the power component is controlled to operate at a low speed to allow the heat exchange medium to flow and exchange heat with the casing around the air outlet, thereby preventing condensation.

[0080] Optionally, in step S144, when the indoor relative humidity is greater than or equal to a second humidity threshold, it indicates a risk of condensation, and the indoor fan speed is increased to the second speed. After the indoor fan speed is increased to the second speed, if the difference between the indoor temperature and the temperature of the casing around the air outlet is greater than or equal to a second preset value, the indoor relative humidity is high, and the temperature difference is also large, indicating a very high risk of condensation. At this time, the heating component and the power component are controlled to operate. Specifically, the heating component is controlled to operate at the third setting, i.e., at a high temperature setting, to increase the heating temperature of the heat exchange medium, and the power component is controlled to operate at a high speed setting to increase the heat exchange between the heat exchange medium and the casing around the air outlet, thereby effectively preventing the generation of condensation.

[0081] Thus, when the indoor relative humidity is greater than or equal to the second humidity threshold, the indoor fan speed is increased to the second speed. By significantly increasing the indoor fan speed, the outlet air temperature is increased, reducing the probability of condensation. Simultaneously, when the difference between the indoor temperature and the temperature of the casing around the air outlet is greater than a first preset value but less than a second preset value, the heating component is controlled to operate at a medium temperature setting and the power component at a low speed setting; or, when the difference between the indoor temperature and the temperature of the casing around the air outlet is greater than or equal to the second preset value, the heating component is controlled to operate at a high temperature setting and the power component at a high speed setting. Through these methods, the heat exchange medium heats the casing around the air outlet, fundamentally preventing condensation. By controlling the heating and power components in different ways, the temperature difference between the casing around the air outlet and the indoor temperature is reduced, thereby improving the effectiveness of preventing condensation.

[0082] It should be noted that the specific implementation methods of steps S101, S102 and S103 can be found in the above embodiments, and will not be repeated here.

[0083] Optionally, combined Figure 7 As shown in the embodiments of this disclosure, another method for preventing condensation in air conditioners is provided, including:

[0084] S101, the processor determines the indoor relative humidity when running in cooling / dehumidification mode during the summer.

[0085] S102, the processor adjusts the indoor fan speed according to the indoor relative humidity.

[0086] S103, the processor determines the temperature difference between the indoor temperature and the surrounding housing temperature of the air outlet.

[0087] S104, the processor controls the heating component to heat the heat exchange medium and controls the power component to drive the flow of the heated heat exchange medium based on the indoor fan speed and temperature difference.

[0088] S105, after the heating component and the power component have been running for a set period of time, the processor determines the current indoor temperature and the current housing temperature around the air outlet.

[0089] S106, if the difference between the current indoor temperature and the current housing temperature around the air outlet is less than a third preset value, the processor controls the heating component and the power component to stop operating.

[0090] Optionally, the third preset difference is less than the first preset difference. Optionally, the third preset difference is 1°C.

[0091] After the heating and power components have been running for a set period of time, if the difference between the current indoor temperature and the temperature of the casing around the air outlet is less than a third preset value, it indicates that the indoor temperature and the temperature of the casing around the air outlet are not significantly different. In other words, by adjusting the indoor fan speed and controlling the operation of the heating and control components, condensation can be effectively prevented. At this point, the heating and power components are stopped.

[0092] Optionally, the preset duration is 3 to 10 minutes, and can be adjusted according to actual needs.

[0093] Optionally, the method for preventing condensation in an air conditioner further includes: when the indoor fan speed is increased to a first speed and the temperature difference is less than or equal to a first preset difference, or when the indoor fan speed is increased to a second speed and the temperature difference is less than or equal to the first preset difference, the processor controls the heating component and the power component to remain in a stopped state.

[0094] In this solution, after the processor increases the indoor fan speed to the first speed or the second speed, if the temperature difference between the detected indoor temperature and the temperature of the casing around the air outlet is less than or equal to the first preset difference, it means that the risk of condensation is very low. At this time, controlling the indoor fan to run at the first speed or the second speed to increase the air outlet temperature can prevent condensation from occurring.

[0095] Optionally, the method for preventing condensation in air conditioning further includes: when the relative humidity in the room is less than or equal to a first humidity threshold, the controller controls the rotation speed of the indoor fan to remain constant and controls the heating component and the power component to remain in a stopped state.

[0096] In other words, in this solution, if the indoor relative humidity is less than or equal to the first humidity threshold, it means that condensation will not occur. The indoor fan speed is kept constant, and the heating and power components are kept off to maintain the normal operation of the indoor air conditioning unit.

[0097] Combination Figure 8 As shown, this disclosure provides an anti-condensation device for an indoor unit of an air conditioner, comprising: a first determining module 81, a fan speed regulating module 82, a second determining module 83, and a control module 84. The first determining module 81 is configured to determine the indoor relative humidity when operating in cooling / dehumidification mode during summer. The fan speed regulating module 82 is configured to adjust the indoor fan speed according to the indoor relative humidity. The second determining module 83 is configured to determine the temperature difference between the indoor temperature and the temperature of the casing surrounding the air outlet. The control module 84 is configured to control the heating component to heat the heat exchange medium and control the power component to drive the heated heat exchange medium to flow, based on the indoor fan speed and the temperature difference.

[0098] The device for preventing condensation in an air conditioner indoor unit provided in this embodiment of the invention addresses the issue that the rotational speed of the indoor fan affects the indoor ambient temperature and thus the formation of condensation. Therefore, based on the indoor relative humidity, it determines whether condensation is likely at the air outlet of the indoor unit. If condensation is possible, the device controls the indoor fan speed to initially increase the outlet air temperature, thus preventing condensation. Furthermore, based on the adjusted fan speed and the temperature difference between the indoor temperature and the surrounding casing temperature at the air outlet, it controls the operation of the heating and power components, further preventing condensation from forming on the casing around the air outlet. In this way, by adjusting the indoor fan speed and controlling the operation of the heating and power components when condensation is possible, the device suppresses condensation, improves the effectiveness of preventing condensation, prevents water leakage, and enhances user comfort when using the air conditioner.
