[0030] Figure 2 FIG. 1 is a flow chart of a method for preventing odor from being blown out of an air conditioner according to an embodiment of the present application. Figure 2 As shown, the method comprises the following steps:

[0031] Step S201, obtaining the indoor dew point temperature and the indoor ambient humidity, and determining the temperature critical value according to the indoor dew point temperature and the indoor ambient humidity;

[0032] Specifically, the dew point temperature is the temperature at which water vapor in the air begins to condense into water droplets. In air conditioning control methods, knowing the dew point temperature is crucial to managing the dehumidification function of the air conditioner. The dew point temperature can be calculated from the temperature and humidity values ​​of the indoor air obtained by the humidity sensor and temperature sensor built into the air conditioner. Indoor ambient humidity is usually measured by a humidity sensor, which reflects the content of water vapor in the indoor air, expressed in the form of relative humidity (RH), which ranges from 0% (absolute dryness) to 100% (saturation). Humidity is a key parameter in air conditioning control because it affects the condensation and formation of condensed water on the evaporator surface, which indirectly affects the adsorption and release of odors. The temperature threshold is a strategic set value used to control the inner tube temperature of the air conditioner. It is calculated based on the indoor dew point temperature and ambient humidity, and its purpose is to ensure that a certain thickness of water film is maintained on the evaporator surface to adsorb odor molecules.

[0033] Step S202, if the temperature of the inner tube of the air conditioner is greater than the temperature threshold when the air conditioner is turned on, lowering the temperature of the inner tube of the air conditioner to less than or equal to the temperature threshold;

[0034] Specifically, this step focuses on how to adjust the temperature of the inner tube (evaporator) when the air conditioner is started to ensure that it does not exceed a specific temperature threshold, which helps to form and maintain a water film on the surface of the evaporator, thereby preventing odor from being blown out of the room. In the early stage of air conditioning cooling operation, the evaporator surface temperature may be relatively high, which is not conducive to the formation of a water film. The formation of a water film on the evaporator surface is achieved by condensing the moisture carried in the air, and a thicker water film can help capture and fix odor molecules in the room to prevent them from being re-released into the environment with the air flow. If the temperature on the evaporator surface is higher than the critical value, water vapor may not condense to form a sufficient water film, or the formed water film will evaporate quickly, which will reduce its ability to absorb odors. Inner tube temperature (evaporator temperature), which refers to the temperature inside the air conditioner, especially the evaporator part. In the air conditioning cooling mode, the evaporator temperature is usually lower than the ambient temperature to promote the condensation of moisture in the air. The temperature threshold is a target temperature value calculated based on the dew point temperature and humidity of the indoor environment. This value is set low enough to ensure that a sufficiently thick water film can form and remain on the evaporator surface, but not so low that it affects the normal operation or energy efficiency of the air conditioner.

[0035] Once the air conditioner is started, the system immediately detects whether the inner tube temperature is greater than the temperature threshold calculated based on the current indoor environment. If it is detected that the inner tube temperature is indeed higher than the temperature threshold, the inner tube temperature is rapidly reduced by increasing the operating frequency of the compressor until it reaches or falls below the temperature threshold. Increasing the compressor frequency means more refrigerant circulation, which can reduce the temperature of the evaporator faster. Once the inner tube temperature drops to or below the temperature threshold, the system will maintain this temperature condition to ensure that the evaporator surface can form and maintain an appropriate water film to capture and fix odor molecules.

[0036] Through this step, the air conditioner can quickly form an environment that is conducive to absorbing odors at the initial start-up, thereby avoiding odor problems in subsequent operation. At the same time, by accurately controlling the temperature of the inner tube, it is possible to minimize energy consumption and improve the operating efficiency of the air conditioner while ensuring the anti-odor effect. The core of this step is to monitor and dynamically adjust the temperature of the evaporator in real time to ensure that it is maintained within a temperature range that is conducive to the formation and maintenance of the water film, thereby effectively preventing the release of odors during the operation of the air conditioner.

[0037] Step S203, during the cooling process of the air conditioner, if the indoor ambient temperature drops to a first preset temperature value, the wind speed is reduced to a first preset level while controlling the reduction of the compressor frequency. Thereafter, when the indoor ambient temperature drops to the shutdown temperature, the wind speed is adjusted to a second preset level and the compressor frequency is adjusted according to the temperature rise rate so that the thickness of the water film on the evaporator surface is greater than the preset thickness to prevent odor from being blown out.

[0038] Specifically, when the air conditioner starts the cooling function, the indoor ambient temperature will gradually decrease. Once the temperature drops to the first temperature preset value, the air conditioner control logic will intervene and begin to reduce the operating frequency of the compressor, while adjusting the wind speed to the first preset gear. This temperature preset value is usually set to be slightly higher than the final shutdown temperature. The purpose of this is to slow down the further drop in indoor temperature and avoid the water film on the surface of the evaporator evaporating too quickly, thereby reducing the generation of odor. The first preset gear is usually a lower wind speed level because it helps to slow down the air flow rate and thus slow down the evaporation of the water film on the surface of the evaporator. In the embodiment of the present application, the first preset gear can be set to below the medium and low wind speed.

[0039] As the air conditioner continues to run, the indoor ambient temperature will continue to drop until it reaches the shutdown temperature. At this time, the air conditioner will further adjust the wind speed to the second preset gear, which is usually lower than the first preset gear, to further slow down the air flow rate and prevent the water film on the surface of the evaporator from being quickly dried. In the embodiment of the present application, the second preset gear can be set to a silent gear. At the same time, the air conditioner will adjust the frequency of the compressor according to the temperature rise rate of the indoor temperature. The temperature rise rate refers to the speed at which the indoor temperature begins to gradually rise after the air conditioner is shut down. If the temperature rise rate is small, it means that the indoor environment can absorb moisture from the surface of the evaporator more slowly. At this time, the air conditioner will run at a lower compressor frequency. Otherwise, the compressor frequency will be increased to form a water film faster when needed, keep the surface of the evaporator moist, and prevent odor molecules from being blown out with the evaporation of the water film.

[0040] The adjustment of the compressor frequency is related to the temperature rise rate of the indoor temperature. If the temperature rise rate is fast, the compressor frequency will increase accordingly to form a water film faster; conversely, if the temperature rise rate is slow, the compressor frequency will decrease to reduce energy consumption while ensuring the stability of the water film. At different stages, the wind speed will be adjusted to different preset gears. In the early stage, in order to quickly form a water film, a higher wind speed may be set; when approaching the shutdown temperature, the wind speed will be reduced to slow down the evaporation rate of the water film, thereby more effectively capturing and fixing odor molecules.

[0041] The above steps ensure that the water film on the evaporator surface is maintained at an appropriate thickness at all stages of air-conditioning operation, thereby preventing the emission of odor during the refrigeration process.

[0042] In one embodiment of the present application, obtaining the indoor dew point temperature includes: using the first formula Calculate the indoor dew point temperature T d , where T is the indoor environment temperature, W is the indoor environment humidity, and a, b, c, and d are constants.

[0043] Specifically, the dew point temperature It is very important for air conditioning control because it directly affects whether a sufficient water film can be formed on the evaporator surface, and thus whether odor molecules can be effectively adsorbed and fixed. T is the indoor ambient temperature in degrees Celsius; W is the indoor ambient humidity in percentage (0% to 100%); a, b, c, d are constants used for calculation, which may be different in different calculation models, but are usually calibrated to ensure the accuracy of the calculated dew point temperature. In the embodiment of this application, a is 273.7, b is 17.27, c is 237.7, and d is 100.

[0044] In one embodiment of the present application, determining the temperature threshold according to the indoor dew point temperature and the indoor ambient humidity includes: according to the second formula Tm=Td -k*(1-W)±γ determines the temperature critical value Tm, where γ is the temperature correction value, T d is the above-mentioned indoor dew point temperature, W is the above-mentioned indoor ambient humidity, and k is a constant.

[0045] Specifically, according to the indoor dew point temperature T d and the indoor ambient humidity W to determine the temperature critical value Tm = T d -k*(1-W)±γ, calculated by the second formula to ensure that the evaporator surface maintains an appropriate water film thickness, thereby preventing odor molecules from being re-released into the indoor air. The indoor dew point temperature is calculated by the above first formula, which is the temperature point at which water vapor in the air begins to condense; the indoor ambient humidity is expressed in percentage; the constant k is used to adjust the relationship between the dew point temperature and the ambient humidity to ensure that the pipe temperature inside the air conditioner is within a temperature range that is conducive to the formation and maintenance of a water film. In this embodiment of the application, the constant k can be set to 10. The temperature correction value γ allows fine-tuning based on the calculated temperature critical value to adapt to different environmental conditions and air conditioning models. In this embodiment of the application, the value range of γ is -2°C to 2°C.

[0046] When the ambient humidity W is high, the value of (1-W) is small, and the influence of the subtraction part in the formula will be reduced accordingly, which means that the temperature critical value Tm is closer to the dew point temperature T d On the contrary, when the ambient humidity is low, the value of (1-W) is larger, and the temperature threshold Tm will be higher than the dew point temperature T d Lower, to ensure that sufficient water film can be formed in a dry environment. The role of the temperature correction value γ is to provide a certain temperature range to adapt to the formation and maintenance of water film on the evaporator surface under different conditions. For example, in an extremely dry or humid environment, γ can help adjust the temperature of the air conditioner pipe to ensure the stability of the water film.

[0047] The calculation of the temperature threshold is an accurate and dynamic process. It is based on the real-time indoor dew point temperature and humidity conditions. By calculating and setting the temperature threshold according to the second formula, the air conditioner can dynamically adjust its operating state to ensure that the evaporator surface maintains sufficient water film thickness regardless of how the indoor environmental conditions change.

[0048] In one embodiment of the present application, the method further includes: if the temperature of the inner tube of the air conditioner is less than or equal to the temperature critical value when the air conditioner is turned on, maintaining the temperature of the inner tube of the air conditioner unchanged.

[0049] Specifically, this step can ensure that when the air conditioner is started, if the temperature of the evaporator (inner tube) is already in a state that is conducive to the formation and maintenance of a water film, that is, less than or equal to the calculated temperature critical value, then the air conditioner will not make additional adjustments to the temperature of the evaporator. In the early stage of air conditioning operation, if the temperature of the evaporator is already low enough to cause the moisture in the air to condense into a water film, then there is no need to further lower the evaporator temperature. Too low an evaporator temperature will not only increase energy consumption, but may also affect the comfort of the indoor environment, such as causing the indoor air to be too dry. Therefore, this strategy aims to avoid unnecessary energy consumption and maintain the comfort of the indoor environment.

[0050] When the air conditioner is turned on, the system will first read the current temperature of the evaporator, that is, the inner tube temperature. Then, the temperature critical value is calculated based on the indoor dew point temperature and ambient humidity. After comparing the inner tube temperature with the temperature critical value, if it is less than or equal to the temperature critical value, it means that the evaporator temperature is low enough to form a water film and absorb odor molecules. At this time, the air conditioner will not take additional cooling measures to reduce the evaporator temperature, avoid unnecessary high-frequency operation of the compressor and fan, thereby saving energy, reducing noise, and improving the comfort of the indoor environment.

[0051] In one embodiment of the present application, the method further includes: determining the first temperature preset value T1 according to a third formula T1=Ts+τ, wherein Ts is the shutdown temperature and τ is the temperature revision value.

[0052] Specifically, the calculation and application of the first temperature preset value is an important part of the air conditioner's anti-odor control strategy. It ensures the formation and maintenance of a water film on the evaporator surface based on the shutdown temperature set by the user and the additional temperature revision value, thereby effectively preventing the release of odor molecules and taking into account energy efficiency and indoor comfort. The third formula T1 = Ts + τ is used to calculate a temperature threshold (the first temperature preset value T1). When the air conditioner reaches this temperature threshold, it will start to take measures to reduce the compressor frequency and wind speed to slow down the rate of indoor temperature drop, thereby ensuring that a sufficient water film is formed and maintained on the evaporator surface to prevent odor problems. The shutdown temperature is the temperature point at which the compressor will stop working when the air conditioner reaches a predetermined temperature in cooling mode. The shutdown temperature is the indoor target temperature set by the user, and the air conditioner will strive to keep the indoor ambient temperature close to this set value. The temperature revision value is used to add a temperature range based on the shutdown temperature, which is defined as the first temperature preset value T1. The introduction of the temperature revision value is to ensure that when the air conditioner is close to the shutdown temperature, the water film on the evaporator surface is thick enough to continue to absorb odor molecules after the air conditioner is shut down, preventing them from being blown into the room as the water film on the evaporator surface evaporates. In the embodiment of the present application, 0<τ≤2℃.

[0053] By calculating the first temperature preset value T1, the air conditioner can control the cooling process more accurately and ensure that a sufficiently thick water film has been established on the evaporator surface before the air conditioner is shut down. This not only helps to absorb the odor molecules in the room and prevent the odor molecules from being released again with the evaporation of the water film on the evaporator surface after the air conditioner is shut down, but also can prolong the maintenance time of the water film on the evaporator surface by slowing down the speed at which the air conditioner reaches the preset shutdown temperature, thereby improving the deodorization effect. In addition, by appropriately setting the value of τ, the cooling efficiency and deodorization function can be balanced to ensure that the air conditioner effectively prevents odor problems while maintaining indoor comfort.

[0054] In one embodiment of the present application, calculating the above-mentioned temperature rise rate includes: using the fourth formula Ki=(Ti2-Ti1) / Δt to calculate the above-mentioned temperature rise rate Ki, wherein Δt is a preset time period, Ti2 is the indoor ambient temperature at the initial moment of Δt, and Ti1 is the indoor ambient temperature at the end moment of Δt.

[0055] Specifically, the temperature rise rate is used to monitor and evaluate the speed at which the indoor temperature rises after the air conditioner is shut down, thereby guiding the air conditioner on how to adjust the compressor frequency and wind speed to maintain the water film on the surface of the evaporator and prevent the release of odor molecules. The fourth formula Ki = (Ti2-Ti1) / Δt is used to calculate the temperature rise rate Ki, that is, the rate of change of the indoor ambient temperature within the set time period Δt. By monitoring this rate of change, the air conditioning system can evaluate the evaporation rate of the water film on the surface of the evaporator, and then take corresponding control measures to ensure the continued existence and integrity of the water film. Δt is a preset time period, which is a fixed time interval used to calculate the temperature rise rate. In the embodiment of the present application, 1s≤Δt≤5s. Ti2 is the indoor ambient temperature at the initial moment of Δt, that is, the indoor temperature reading before or when the air conditioner is shut down. After the air conditioner is shut down, the system begins to monitor the change of the indoor temperature and records the indoor temperature Ti2 when it is shut down; at the end of the preset time period Δt, the indoor ambient temperature is read again, recorded as Ti1; the temperature rise rate is calculated using the fourth formula Ki = (Ti2-Ti1) / Δt.

[0056] The following are examples:

[0057] Hypothetical scenario:

[0058] Initial state: the air conditioner is in cooling mode, and the target shutdown temperature is Ts = 25°C.

[0059] After the air conditioner has been running for a period of time, the indoor temperature gradually approaches the shutdown temperature of 25℃.

[0060] Implementation steps:

[0061] Once the temperature sensor detects that the indoor ambient temperature has reached the air conditioner shutdown setting of 25°C, the system responds immediately and adjusts the wind speed to the silent gear. The purpose of this operation is to slow down the air flow speed, thereby reducing the evaporation rate of the water film on the evaporator surface. While the wind speed is adjusted to the silent gear, the system starts to calculate the temperature rise rate Ki, that is, the rate of change of the indoor temperature within the set time period Δt. Assuming Δt = 3 seconds, the system calculates the temperature rise rate every 3 seconds.

[0062] Ti2 is the indoor ambient temperature when the air conditioner is stopped, for example, Ti2 = 25°C.

[0063] Ti1 is the indoor ambient temperature after 3 seconds, assuming that Ti1 = 25.1°C at this time.

[0064] According to the calculation formula of temperature rise rate Ki, the temperature rise rate is 0.0333℃ / s, which means that within a time interval of 3 seconds, the indoor ambient temperature rises by 0.0333℃ / s.

[0065] Specific examples are:

[0066] Assume that after the air conditioner has been running for a period of time at night, the user is ready to take a break and the air conditioner is about to enter standby mode. Before the air conditioner stops, the system records the indoor temperature Ti2 = 21.8°C. The preset time period of 4s is selected to monitor the temperature rise rate. After 4s, the system reads the indoor temperature again, and the temperature has dropped to Ti1 = 22°C. The temperature rise rate can be calculated according to the fourth formula. The calculated temperature rise rate Ki = 0.175°C / s indicates that the indoor temperature rises by about 0.05°C per second after the air conditioner stops. This rate can reflect the evaporation of the water film on the evaporator surface.

[0067] In one embodiment of the present application, the compressor frequency is adjusted according to the temperature rise rate, including: when the temperature rise rate is less than the first preset rate, controlling the compressor to operate at the first preset frequency; when the temperature rise rate is greater than or equal to the first preset rate and less than the second preset rate, controlling the compressor to operate at the second preset frequency; when the temperature rise rate is greater than or equal to the second preset rate, controlling the compressor to operate at the third preset frequency, wherein the first preset frequency is less than the second preset frequency, and the second preset frequency is less than the third preset frequency.

[0068] Specifically, a lower temperature rise rate threshold K1 is set. In the embodiments of the present application, 0 < K1 ≤ 0.1 °C / min. When the monitored indoor temperature rise rate is less than K1, the system considers that the water film evaporation on the evaporator surface is slow. Therefore, the compressor can be controlled to operate at a lower frequency (the first preset frequency), which helps to save energy and ensure the maintenance of the water film. In the embodiments of the present application, the first preset frequency is a low frequency. A medium temperature rise rate threshold K2 is set. In the embodiments of the present application, 0.1 °C / min < K2 ≤ 0.2 °C / min, which is between the first preset rate K1 and a higher value. When the temperature rise rate Ki is between K1 and K2, the evaporation rate of the water film on the evaporator surface is moderate, and the system needs to increase the frequency of the compressor and operate at the second preset frequency to maintain the existence of the water film. In the embodiments of the present application, the second preset frequency is a medium frequency. A higher temperature rise rate threshold is set. When the temperature rise rate Ki is equal to or exceeds K2, it indicates that the evaporation rate of the water film on the evaporator surface is fast. To ensure the continuous existence of the water film, the system will control the compressor to operate at a higher frequency (the third preset frequency). In the embodiments of the present application, the third preset frequency is a high frequency.

[0069] The operating frequency of the compressor is adjusted according to the magnitude of the temperature rise rate Ki. For example: Assume that the first preset rate K1 is 0.05 °C / s and the second preset rate K2 is 0.13 °C / s.

[0070] If Ki < K1, that is, 0.0333 °C / s < 0.05 °C / s, the system determines that the evaporation rate of the water film on the evaporator surface is slow, and a lower compressor frequency can be used to operate to maintain the water film and save energy.

[0071] If K1 ≤ Ki < K2, for example, 0.05 °C / s ≤ Ki < 0.1 °C / s, the system considers that the evaporation rate is moderate, and the compressor may need to operate at a medium frequency to ensure that there is sufficient water film coverage on the evaporator surface.

[0072] If Ki ≥ K2, that is, the water film on the evaporator surface evaporates rapidly, the compressor will be adjusted to operate at a higher frequency to increase the condensate water volume on the evaporator surface and form a thicker water film, thereby effectively preventing the release of odor molecules.

[0073] By calculating the temperature rise rate Ki and comparing the first preset rate K1 with the second preset rate K2, the air conditioning system can intelligently control the operating frequency of the compressor to ensure that the water film on the evaporator surface is maintained during a critical period after shutdown, thereby effectively preventing odor problems, improving indoor air quality and the user's living experience. This dynamic adjustment strategy not only solves the odor problem but also takes into account the energy efficiency of the air conditioner and the user's comfort.

[0074] By monitoring the indoor temperature rise rate in real time and dynamically adjusting the compressor frequency, the air conditioning system can effectively maintain the thickness of the water film on the evaporator surface, preventing odor molecules from being released back into the indoor air as the water film evaporates. This method not only solves the odor problem, but also intelligently adjusts the air conditioning operation status according to environmental changes, improves the energy efficiency of the air conditioning, and reduces unnecessary energy consumption.

[0075] In order to enable those skilled in the art to more clearly understand the technical solution of the present application, the implementation process of the method for preventing odor from being blown out of an air conditioner of the present application will be described in detail below in combination with specific embodiments.

[0076] This embodiment relates to a specific method for preventing the air conditioner from blowing out odors, such as Figure 3 As shown, including:

[0077] Air conditioning refrigeration, the starting point of the process, the air conditioner starts cooling mode, providing cold air to the room and lowering the indoor temperature.

[0078] The temperature sensing package determines the ambient temperature T, and the humidity sensor determines the humidity W. The temperature sensing package and the humidity sensor collect the current temperature and humidity data in the room respectively. These data are used for subsequent dew point temperature calculation and control strategy formulation.

[0079] Calculate the dew point temperature T based on T and W d , using the indoor environment temperature T and humidity W to calculate the dew point temperature (T d ).

[0080] Control the inner tube temperature Tn≤T d -k*(1-W)±γ: The system will control the temperature Tn of the evaporator (inner tube) to remain within a preset range, in order to ensure that the water film on the surface of the evaporator reaches a certain thickness during the refrigeration process to absorb odor molecules.

[0081] Determine whether the indoor ambient temperature reaches the first temperature preset value T1. If the indoor ambient temperature reaches the first temperature preset value T1, the system will reduce the compressor frequency, reduce the wind speed, and adjust the position of the air guide plate to slow down the speed of reaching the shutdown temperature, thereby increasing the maintenance time of the water film on the evaporator surface; if the indoor ambient temperature does not reach the first temperature preset value T1, continue to control the inner pipe temperature Tn≤T d -k*(1-W)±γ.

[0082] Determine whether the indoor ambient temperature has reached the shutdown temperature Ts. If the indoor ambient temperature has reached the shutdown temperature Ts, the air conditioner will be adjusted to the silent wind speed and start calculating the indoor temperature rise rate Ki. If the indoor ambient temperature has not reached the shutdown temperature Ts, the compressor frequency will continue to be reduced, the wind speed will be reduced, and the position of the air guide plate will be adjusted.

[0083] The compressor frequency is adjusted according to the Ki range. The system continuously monitors the indoor temperature rise rate Ki after shutdown and adjusts the compressor operating frequency according to its value to maintain the water film state on the evaporator surface and prevent odor molecules from being re-released as the water film evaporates.

[0084] An embodiment of the present invention provides an air conditioner, comprising: a humidity sensor for monitoring indoor environmental humidity; a temperature sensing package for monitoring indoor environmental temperature; and a controller for communicating with the humidity sensor and the temperature sensing package, and for executing any one of the above-mentioned methods for preventing odor from being blown out of the air conditioner.

[0085] Specifically, the humidity sensor is used to monitor the humidity level of the indoor environment in real time. The humidity sensor can accurately capture the changes in the moisture content in the air, which is crucial for calculating the dew point temperature and determining the conditions for the formation of the water film on the surface of the evaporator. The temperature sensing package is a device used to monitor the indoor ambient temperature. It can continuously detect the indoor temperature and help the system determine whether the air conditioner is close to the preset shutdown temperature and the recovery speed of the indoor temperature after shutdown. The controller communicates with the humidity sensor and the temperature sensing package, receives data from the two sensors, and executes the above-mentioned control method for preventing the air conditioner from blowing out odor based on these data. The controller can decide when to adjust the frequency, wind speed and position of the air guide plate of the compressor through algorithm processing to maintain the thickness of the water film on the surface of the evaporator and prevent the diffusion of odor molecules. The above-mentioned air conditioner also has an indoor heat exchanger with a hydrophilic coating on the surface to improve the heat exchange efficiency of the air conditioner; the above-mentioned air conditioner also has air inlet, air outlet, cross-flow fan, air guide plate, compressor and other components.

[0089] Step S202, if the temperature of the inner tube of the air conditioner is greater than the temperature threshold when the air conditioner is turned on, lowering the temperature of the inner tube of the air conditioner to less than or equal to the temperature threshold;

[0090] Step S203, during the cooling process of the air conditioner, if the indoor ambient temperature drops to a first preset temperature value, the wind speed is reduced to a first preset level while controlling the reduction of the compressor frequency. Thereafter, when the indoor ambient temperature drops to the shutdown temperature, the wind speed is adjusted to a second preset level and the compressor frequency is adjusted according to the temperature rise rate so that the thickness of the water film on the evaporator surface is greater than the preset thickness to prevent odor from being blown out.
