[0032] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0034] The operating principle of the air conditioner involved in the embodiments of this application is described in detail below:

[0035] like Figure 1As shown, the compressor compresses the refrigerant and delivers it through pipes to the condenser. The high-temperature, high-pressure gaseous refrigerant releases heat in the condenser, transforming into a medium-temperature, high-pressure liquid refrigerant. Then, the medium-temperature, high-pressure liquid refrigerant is depressurized through a capillary tube (throttling unit) to become a low-temperature, low-pressure liquid refrigerant. This low-temperature, low-pressure liquid refrigerant is then delivered to the evaporator, where it evaporates into a gas, absorbing a large amount of heat during the evaporation process. Finally, the low-temperature, low-pressure gaseous refrigerant in the evaporator is delivered to the compressor to participate in the next cycle. When the air conditioner is cooling, the outdoor unit's heat exchanger acts as the condenser, and the indoor unit's heat exchanger acts as the evaporator; conversely, when the air conditioner is heating, the outdoor unit's heat exchanger acts as the evaporator, and the indoor unit's heat exchanger acts as the condenser.

[0036] An air conditioner indoor unit includes a casing, a fan, and a heat exchanger housed within the casing. The heat exchanger is located on one side facing the fan's air outlet. The casing has an air outlet and an air inlet. When the indoor unit is running, the fan operates, directing air towards the evaporator to blow out either cool or warm air from the outlet. However, in practical applications, the air blown from the indoor unit's outlet sometimes has a sour or foul odor, severely impacting the user experience.

[0037] In related technologies, besides odors caused by factors such as dampness and mold, the odor may also be caused by the hydrophilic aluminum foil coating on the fins of the indoor heat exchanger. Hydrophilic aluminum foil is aluminum foil that has undergone a hydrophilic treatment. Through a special process, a hydrophilic coating layer is applied to its surface. Condensate on the hydrophilic aluminum foil quickly disperses and does not condense into water droplets, increasing the heat exchange area, accelerating cooling and heating speeds, and effectively preventing noise caused by condensate obstructing airflow.

[0038] However, due to the processing technology, improper handling during the production process may result in the coating not being fully cured. The hydrophilic coating will then evaporate into the air when the indoor unit is running, producing a sour smell.

[0039] In view of the odor caused by the hydrophilic aluminum foil coating in related technologies, this application provides a control method for eliminating the odor of the indoor unit of an air conditioner based on the cause of the odor, which can reduce the odor generated by the hydrophilic aluminum foil coating to a certain extent.

[0040] The control method for eliminating odors from indoor units of air conditioners provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0041] like Figure 2 As shown in the embodiment of this application, a control method for eliminating odors from an indoor unit of an air conditioner is provided. This method may include the following steps 201 to 203:

[0042] Step 201: Obtain the first operating parameters used to reflect the current operating status of the air conditioner.

[0043] For example, the above operating parameters may include at least one of the following: the set temperature of the air conditioner, the fan speed of the indoor unit of the air conditioner, and the operating frequency of the compressor.

[0044] It should be noted that the evaporation rate of the hydrophilic aluminum foil coating is affected by temperature; the higher the temperature, the greater the evaporation rate, and the lower the temperature, the smaller the evaporation rate. Therefore, in this embodiment, the evaporation rate of the hydrophilic aluminum foil coating on the fins of the indoor heat exchanger can be reduced by lowering the surface temperature of the indoor unit, thereby reducing odor generation. Simultaneously, to minimize the impact on users, temperature compensation is also achieved by activating the electric heating function of the indoor unit.

[0045] Step 202: If the preset triggering conditions are met, determine the second operating parameters based on the first operating parameters.

[0046] For example, in this embodiment of the application, when it is determined that the preset triggering conditions are met, the surface temperature of the indoor heat exchanger can be reduced by adjusting the set temperature of the air conditioner, the fan speed of the indoor unit of the air conditioner, and the operating frequency of the compressor, so that the air conditioner can reduce the amount of evaporation of the hydrophilic aluminum foil coating while evaporating the moisture adsorbed by the hydrophilic aluminum foil coating.

[0047] Step 203: Control the air conditioner to operate according to the second operating parameters.

[0048] The second operating parameter is used to reduce the ambient temperature around the indoor heat exchanger of the air conditioner; the temperature difference between the first air outlet temperature when the air conditioner operates according to the first operating parameter and the second air outlet temperature when the air conditioner operates according to the second operating parameter is less than a preset temperature difference threshold.

[0049] For example, if the preset triggering conditions are met, the second operating parameters can be determined based on the first operating parameters obtained in the above steps, and the air conditioner can be controlled to operate according to the second operating parameters.

[0050] For example, different first operating parameters correspond to different second operating parameters. The control method for eliminating odors in the indoor unit of an air conditioner provided in this application embodiment can reduce the surface temperature of the indoor heat exchanger while ensuring that the air outlet temperature of the air conditioner when operating according to the second operating parameters is consistent with the air outlet temperature of the air conditioner when operating according to the first operating parameters (the temperature difference is less than a preset temperature difference threshold).

[0051] For example, the control method for eliminating odors from the indoor unit of an air conditioner provided in this application embodiment can not only suppress the volatilization of the hydrophilic aluminum foil coating layer, but also evaporate the moisture absorbed by the hydrophilic aluminum foil coating layer, thereby slowing down the release rate of odors and reducing the impact on users.

[0052] It should be noted that the control method for eliminating odors from the indoor unit of an air conditioner provided in this application embodiment can be applied not only in summer, but also in winter when humidity is high and temperature is low.

[0053] Optionally, in this embodiment of the application, the preset triggering conditions can be determined based on the current ambient humidity and the time interval between the current running time and the last running time of the air conditioner.

[0054] For example, prior to step 202 above, the control method for eliminating odors from the indoor unit of an air conditioner provided in this application embodiment may further include steps 204 and 205:

[0055] Step 204: Obtain the time interval between the last operation of the air conditioner and the current ambient humidity.

[0056] Step 205: If the time interval is greater than a preset duration and / or the ambient humidity of the current environment is greater than a preset humidity threshold, determine that the preset triggering condition is met.

[0057] It is understandable that the evaporation rate of the hydrophilic aluminum foil coating is affected not only by ambient humidity and temperature but also by the evaporation time. This means that air conditioners that have not been used for a long time will also produce odors when they first start operating. Therefore, when an air conditioner is first run after a long period of inactivity, the control method for eliminating odors from the indoor unit provided in this application is needed to reduce the impact of the odor on the user to some extent.

[0058] Optionally, in this embodiment of the application, when it is determined that the preset triggering condition is met, the second operating parameter can be determined through the following steps.

[0059] For example, the first operating parameters include: a first set temperature, a first compressor operating frequency, and a first fan speed.

[0060] Specifically, step 202 above may include steps 202a and 202b:

[0061] Step 202a: Based on the first set temperature, the first compressor operating frequency, and the first fan speed, determine the second set temperature, the second compressor operating frequency, and the second fan speed.

[0062] Step 202b: Determine the second set temperature, the second compressor operating frequency, the second fan speed, and the electric heating function as the second operating parameters.

[0063] Wherein, the first set temperature is greater than the second set temperature; the first compressor operating frequency is less than the second compressor operating frequency; and the first fan speed is greater than the second fan speed.

[0064] It is understood that the control method for eliminating odors from the indoor unit of an air conditioner provided in this application requires heat compensation after adjusting the operating parameters of the air conditioner to reduce the surface temperature of the fins of the indoor heat exchanger, in order to avoid the air supply temperature being too low and causing discomfort to the user.

[0065] Specifically, step 202a above may also include steps 202a1 to 202a3:

[0066] Step 202a1: Calculate the target difference between the current ambient humidity and the preset humidity threshold.

[0067] Step 202a2: Determine the temperature adjustment value, operating frequency adjustment value, and fan speed adjustment value based on the target difference.

[0068] Step 202a3: Calculate the second set temperature based on the first set temperature and the temperature adjustment value; calculate the second compressor operating frequency based on the first compressor operating frequency and the operating frequency adjustment value; and calculate the second fan speed based on the first fan speed and the fan speed adjustment value.

[0069] Specifically, the temperature adjustment value is positively correlated with the target difference; the operating frequency adjustment value is positively correlated with the target difference; and the fan speed adjustment value is positively correlated with the target difference.

[0070] Understandably, the larger the target difference mentioned above, the greater the temperature value, operating frequency value, and fan speed value that need to be adjusted, so that the air conditioner can operate in a low-temperature, low-speed, and high-frequency state.

[0071] Furthermore, in one possible implementation, in order to avoid the low-temperature air conditioning air blowing directly on the user, when implementing the control method for eliminating odors from the indoor unit of the air conditioner provided in this application embodiment, it is also necessary to adjust the air guide plate upward.

[0072] Specifically, step 203 above may also include the following step 203a:

[0073] Step 203a: Control the air conditioner to operate according to the second operating parameters, and control the air guide plate of the air conditioner to move upward.

[0074] For example, by adjusting the airflow direction and using a low airflow speed, the air conditioner can minimize its impact on the user's normal use when performing the control method for eliminating odors from the indoor unit of the air conditioner provided in the embodiments of this application.

[0075] Optionally, in this embodiment of the application, after the air conditioner has been controlled to run for a preset time according to the second operating parameters, the water adsorbed by the hydrophilic aluminum foil coating is completely evaporated. At this time, the air conditioner can be controlled to return to its previous operating state.

[0076] For example, after step 203 above, the control method for eliminating odors from the indoor unit of an air conditioner provided in this application embodiment may further include the following step 206:

[0077] Step 206: After the air conditioner has been running for a preset time according to the second operating parameters, control the air conditioner to run according to the first operating parameters.

[0078] For example, after the air conditioner is controlled to resume operation, in order to reduce or avoid the volatilization of the hydrophilic aluminum foil coating, the following steps can be used for control.

[0079] For example, after step 203 above, the control method for eliminating odors from the indoor unit of an air conditioner provided in this embodiment may further include the following steps 207 and 208:

[0080] Step 207: When the air conditioner is in cooling mode, determine the target fan speed based on the compressor operating frequency indicated by the first operating parameter and the current ambient humidity.

[0081] Step 208: Control the fan of the air conditioner to run at the target fan speed so that a condensate film is formed on the surface of the fins of the indoor heat exchanger.

[0082] Understandably, when an air conditioner is running in cooling mode, condensation will form on the surface of the indoor heat exchanger. By controlling the fan speed, the evaporation rate of the condensation can be controlled, allowing the condensation to form a water film on the fins of the indoor heat exchanger. This water film effectively prevents the evaporation of the hydrophilic aluminum foil coating, thereby reducing odor.

[0083] The control method for eliminating odors from an air conditioner indoor unit provided in this application embodiment acquires a first operating parameter reflecting the current operating state of the air conditioner; under the condition of satisfying a preset triggering condition, a second operating parameter is determined based on the first operating parameter; the air conditioner is controlled to operate according to the second operating parameter; wherein, the second operating parameter is used to reduce the ambient temperature around the indoor heat exchanger of the air conditioner; the temperature difference between the first outlet air temperature when the air conditioner operates according to the first operating parameter and the second outlet air temperature when the air conditioner operates according to the second operating parameter is less than a preset temperature difference threshold. In this way, the odor generated by the volatilization of the hydrophilic aluminum foil coating layer during air conditioner operation can be reduced.

[0084] It should be noted that the control method for eliminating odors from an air conditioner indoor unit provided in this application embodiment can be executed by a control device for eliminating odors from an air conditioner indoor unit, or by a control module within that control device for executing the control method for eliminating odors from an air conditioner indoor unit. This application embodiment uses the example of a control device for eliminating odors from an air conditioner indoor unit executing the control method for eliminating odors from an air conditioner indoor unit to illustrate the control device for eliminating odors from an air conditioner indoor unit provided in this application embodiment.
