[0008] In some embodiments, the method further includes: when it is determined that no condensation has occurred on the first air guide plate, controlling the opening angle of the first air guide plate and the opening angle of the second air guide plate to be the opening angle set by the user.

[0009] In conjunction with the above method, another aspect of the present invention provides an air conditioner control device, comprising: the air conditioner including an indoor unit and an outdoor unit; a first air guide plate and a second air guide plate capable of swinging up and down are provided at the air outlet of the indoor unit; the first air guide plate is located above the second air guide plate; the device includes: an acquisition unit configured to acquire the temperature at the air outlet of the indoor unit, the indoor ambient temperature, the indoor ambient humidity, and the width of the first air guide plate when the air conditioner is operating in cooling mode; wherein the length of a side of the first air guide plate parallel to the air supply direction of the indoor unit is defined as the width of the first air guide plate; a control unit configured to determine whether condensation occurs on the first air guide plate based on the temperature at the air outlet of the indoor unit, the indoor ambient temperature, and the indoor ambient humidity; the control unit is further configured to, when it is determined that condensation occurs on the first air guide plate, control the opening angle of the first air guide plate and the opening angle of the second air guide plate respectively based on the width of the first air guide plate, so that the air blown out by the indoor unit wraps around the surface of the first air guide plate.

[0010] In some embodiments, the control unit determines whether condensation has occurred on the first air guide plate based on the temperature at the indoor unit's air outlet, the indoor ambient temperature, and the indoor ambient humidity, including: calculating the dew point temperature based on the indoor ambient temperature and the indoor ambient humidity; determining the relationship between the temperature at the indoor unit's air outlet and the dew point temperature; and confirming that condensation has occurred on the first air guide plate if the temperature at the indoor unit's air outlet is less than or equal to the dew point temperature.

By adjusting the angle between the first and second air guide plates, cold air is directed directly towards the end of the first air guide plate closest to the indoor side, ensuring that the first air guide plate is completely enveloped by cold air.

[0026] Referring to the accompanying drawings, the reference numerals in the embodiments of the present invention are as follows:

[0027] 102 - Acquisition unit; 104 - Control unit. Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0029] To meet diverse consumer needs, air conditioners are designed with different air deflector angles to achieve requirements such as preventing cold air from blowing directly on people and achieving rapid cooling. As the air conditioner operates at different angles, a zone of hot and cold air inevitably forms on the surface of the air deflector. The fundamental reason for condensation on the indoor unit's air deflector in cooling mode is the presence of this hot and cold air convergence zone; when hot and cold air meet and reach the dew point temperature, condensation occurs.

[0030] Therefore, the present invention provides an air conditioner control method, which sets two air guide plates of different widths at the air outlet of the indoor unit. By adjusting the included angle between the two air guide plates, the air outlet of the indoor unit can wrap around the surface of the two air guide plates, thereby eliminating the formation of a hot and cold convergence zone on the air guide plates and preventing condensation from forming on the air guide plates.

[0031] According to an embodiment of the present invention, a method for controlling an air conditioner is provided, the air conditioner including an indoor unit and an outdoor unit; a first air guide plate and a second air guide plate capable of swinging up and down are provided at the air outlet of the indoor unit; the first air guide plate is located above the second air guide plate; as shown Figure 5 and Figure 6 The structure of the indoor unit of the air conditioner shown includes a heat exchanger, a cross-flow fan, a panel, a bottom casing, a first air guide plate, and a second air guide plate. A temperature monitoring head is installed at the air outlet of the first air guide plate to monitor the temperature at the air outlet of the indoor unit.

[0032] Specifically, the width of the first air guide plate is greater than the width of the second air guide plate. When the first and second air guide plates are open, they divide the indoor unit's air outlet into three airflow areas: the upper area of ​​the first air guide plate, the area between the first and second air guide plates, and the lower area of ​​the second air guide plate. Therefore, when the angle between the first and second air guide plates is at a specific angle, the cold air from the upper area blows directly onto the upper surface of the first air guide plate. Simultaneously, due to the influence of the second air guide plate, the cold air from the middle area blows directly onto the lower surface of the first air guide plate, preventing a hot-cold confluence zone from forming at the indoor side of the first air guide plate, thus preventing condensation. Furthermore, the cold air from the middle area also blows directly onto the upper surface of the second air guide plate, and the cold air from the lower area blows directly onto the lower surface of the second air guide plate, ensuring that condensation does not form on the second air guide plate.

[0033] Optionally, the width of the first air guide plate may not be greater than the width of the second air guide plate, as long as the setting position of the second air guide plate is adjusted so that the second air guide plate affects the air outlet direction and the cold air is blown towards the end of the first air guide plate closer to the indoor side.

[0034] like Figure 1The diagram shows a flowchart of an embodiment of the method of the present invention. The air conditioner control method may include steps S110 to S130.

[0035] In step S110, when the air conditioner is operating in cooling mode, the temperature at the air outlet of the indoor unit, the indoor ambient temperature, the indoor ambient humidity, and the width of the first air guide plate are acquired; wherein, the length of one side of the first air guide plate parallel to the air supply direction of the indoor unit is defined as the width of the first air guide plate. At this time, the opening angle of the first air guide plate and the second air guide plate is at the angle set by the user or the system.

[0036] The width of the first air guide plate is the shorter side of the air guide plate, which is parallel to the airflow direction of the indoor unit and perpendicular to the rotation axis of the air guide plate. Its width is the length of the line connecting the two endpoints of the air guide plate. Figure 7 The width b of the first air guide plate in the middle.

[0037] In step S120, it is determined whether condensation occurs on the first air guide plate based on the temperature at the air outlet of the indoor unit, the indoor ambient temperature, and the indoor ambient humidity.

[0038] Because the width of the first air guide plate is greater than that of the second air guide plate, the first air guide plate is closer to the indoor side, making it more prone to forming a zone of heat and cold converging. Condensation may occur on the first air guide plate but not necessarily on the second air guide plate; however, condensation on the second air guide plate will always occur on the first air guide plate. Therefore, whether or not condensation occurs on the first air guide plate is used as the criterion for judgment.

[0039] In some implementations, step S120 involves determining whether condensation occurs on the first air guide plate based on the temperature at the indoor unit's air outlet, the indoor ambient temperature, and the indoor ambient humidity. Figure 2 As shown, it includes steps S210 to S230.

[0040] Step S210: Calculate the dew point temperature based on the indoor ambient temperature and the indoor ambient humidity.

[0041] The formula for calculating dew point temperature is:

[0042]

[0043] In the formula, t d t is the dew point temperature; t is the indoor ambient temperature; Φ is the indoor ambient humidity.

[0044] Step S220: Determine the relationship between the temperature at the air outlet of the indoor unit and the dew point temperature.

[0045] Step S230: If the temperature at the air outlet of the indoor unit is less than or equal to the dew point temperature, then it is confirmed that condensation has occurred on the first air guide plate.

[0046] In step S130, when it is determined that condensation has occurred on the first air guide plate, the opening angle of the first air guide plate and the opening angle of the second air guide plate are controlled according to the width of the first air guide plate, so that the air blown out by the indoor unit wraps around the surface of the first air guide plate.

[0047] This invention features a second air guide plate at the indoor unit's air outlet. When condensation occurs on the first air guide plate, the angle between the first and second air guide plates is controlled to direct the cold air from the indoor unit directly onto the upper and lower surfaces of the first air guide plate. This ensures the cold air completely envelops the first air guide plate, eliminating the hot and cold convergence zone. While preventing condensation on the first air guide plate, this design does not reduce the indoor fan speed or compressor frequency, maintaining a suitable cooling capacity and ensuring comfort during air conditioning use, thus enhancing the user experience.

[0048] In some embodiments, the specific process of controlling the opening angle of the first air guide plate and the opening angle of the second air guide plate according to the width of the first air guide plate in step S130 is as follows: Figure 3 As shown, it includes steps S310 and S320.

[0049] Step S310: Determine the included angle between the first air guide plate and the second air guide plate based on the width of the first air guide plate.

[0050] like Figure 7 As shown, the angle between the first and second air guide plates is 'a'. The probability 'f' of condensation occurring at the end of the first air guide plate (the end closer to the indoor side) is related to the angle 'a' and the width 'b' of the first air guide plate. Specifically, the relationship between the condensation probability 'f' and the angle 'a' is parabolic; that is, a smaller angle 'a' results in a higher condensation probability 'f', and a larger angle 'a' also results in a higher condensation probability 'f'. Given a fixed width 'b' for the first air guide plate, whether condensation occurs at the end of the first air guide plate is determined by the angle 'a' between the air guide plates.

[0051] Specifically, the relationship between the condensation probability f and the included angle α and the width b of the first air guide plate can be expressed by a function, as follows:

[0052] f = ka 2 +tb+c;

[0053] Where k, t, and c are coefficients derived from fitting experimental test data. Using this functional relationship, given a fixed width b of the first guide vane, the angle between the second and first guide vanes when the probability of condensation at the end of the first guide vane is minimized can be determined. For example, when the width of the first guide vane is 0.91m, the angle between the two guide vanes is 2° when the probability of condensation at the end of the first guide vane is minimized, and the corresponding functional relationship is f = 2a. 2 +3b+10, the calculated f = 20.7, that is, when the angle between the two air guides is 2°, the end of the first air guide is completely covered by cold air, there is no hot and cold air exchange, and condensation will not occur; for example, when the angle between the two air guides is 4°, although the end of the first air guide is also completely covered by cold air, the cold air is relatively thin, and the anti-condensation effect is slightly worse, at which point f = 44.7.

[0054] Step S320: Control the opening angle of the first air guide plate and the opening angle of the second air guide plate according to the included angle, so that the included angle between the first air guide plate and the second air guide plate is the included angle.

[0055] By simultaneously adjusting the opening angles of the first and second air guide vanes, the angle between the two vanes is quickly brought to the angle calculated using a function relationship. This ensures that the end of the first air guide vane is completely surrounded by cold air, preventing condensation. If the air conditioner is in a set mode, such as a mode where the cold air does not blow on people or a rapid cooling mode, the angle of the first air guide vane is fixed. In this case, the opening angle of the second air guide vane can be adjusted so that the angle between the two air guide vanes is the angle calculated using a function relationship.

[0056] In some embodiments, the method further includes: when it is determined that no condensation has occurred on the first air guide plate, controlling the opening angle of the first air guide plate and the opening angle of the second air guide plate to the opening angle set by the user.

[0057] If it is determined that no condensation will occur on the first air guide plate, the angles of the first and second air guide plates will be returned to the user-set opening angles or the system-set angles.

[0058] Figure 8 This is a flowchart illustrating an embodiment of the air conditioning anti-condensation control method for the present invention, as shown below. Figure 8 As shown, the method for controlling condensation on the wind deflector of the present invention includes:

[0059] Step 1: After the air conditioner is turned on and the cooling mode is activated, the first and second air guide vanes at the indoor unit's air outlet are driven by two motors and opened to the set angle. The indoor fan runs at the set speed, and the compressor runs at the set frequency. At this time, the temperature at the indoor unit's air outlet and the indoor temperature and humidity are detected, and Step 2 is executed.

[0060] Step 2: Determine the current dew point temperature based on the indoor temperature and humidity, and determine whether the temperature at the indoor unit's air outlet has reached the dew point temperature; if the temperature at the indoor unit's air outlet has reached the dew point temperature, proceed to Step 3.

[0061] Step 3: Keep the indoor fan speed and compressor frequency unchanged. Control the opening angle of the first and second air guides so that the angle between the two air guides is such that condensation will not occur. Continue to determine the current dew point temperature based on the indoor temperature and humidity. Determine whether the temperature at the indoor unit's air outlet has not reached the dew point temperature. If the temperature at the indoor unit's air outlet has not reached the dew point temperature, control the opening angle of the first and second air guides to the set angle and return to Step 2 to continue execution.

[0062] The technical solution of this embodiment includes a first air guide plate and a second air guide plate that can swing up and down at the indoor unit of the air conditioner. The first air guide plate is located above the second air guide plate. When condensation occurs on the first air guide plate, the opening angles of the first and second air guide plates are controlled respectively. By adjusting the angle between the first and second air guide plates, cold air is directed towards the end of the first air guide plate closest to the indoor side, ensuring that the first air guide plate is completely enveloped by cold air. This prevents the formation of a hot-cold confluence zone, ensuring sufficient cooling capacity while avoiding condensation on the first air guide plate, thus guaranteeing the comfort of air conditioning use and improving the user experience.

[0063] According to an embodiment of the present invention, a control device for an air conditioner corresponding to an air conditioner control method is also provided. The air conditioner includes an indoor unit and an outdoor unit; a first air guide plate and a second air guide plate capable of swinging up and down are provided at the air outlet of the indoor unit; the first air guide plate is located above the second air guide plate; as... Figure 5 and Figure 6 The structure of the indoor unit of the air conditioner shown includes a heat exchanger, a cross-flow fan, a panel, a bottom casing, a first air guide plate, and a second air guide plate. A temperature monitoring head is installed at the air outlet of the first air guide plate to monitor the temperature at the air outlet of the indoor unit.

[0064] Specifically, the width of the first air guide plate is greater than the width of the second air guide plate. When the first and second air guide plates are open, they divide the indoor unit's air outlet into three airflow areas: the upper area of ​​the first air guide plate, the area between the first and second air guide plates, and the lower area of ​​the second air guide plate. Therefore, when the angle between the first and second air guide plates is at a specific angle, the cold air from the upper area blows directly onto the upper surface of the first air guide plate. Simultaneously, due to the influence of the second air guide plate, the cold air from the middle area blows directly onto the lower surface of the first air guide plate, preventing a hot-cold confluence zone from forming at the indoor side of the first air guide plate, thus preventing condensation. Furthermore, the cold air from the middle area also blows directly onto the upper surface of the second air guide plate, and the cold air from the lower area blows directly onto the lower surface of the second air guide plate, ensuring that condensation does not form on the second air guide plate.

[0065] Optionally, the width of the first air guide plate may not be greater than the width of the second air guide plate, as long as the setting position of the second air guide plate is adjusted so that the second air guide plate affects the air outlet direction and the cold air is blown towards the end of the first air guide plate closer to the indoor side.

[0066] See Figure 4 The diagram shows a structural schematic of an embodiment of the device of the present invention. The control device for the air conditioner may include: an acquisition unit 102 and a control unit 104.

[0067] The acquisition unit 102 is configured to acquire the temperature at the air outlet of the indoor unit, the indoor ambient temperature, the indoor ambient humidity, and the width of the first air guide plate when the air conditioner is operating in cooling mode; wherein, the length of one side of the first air guide plate parallel to the air supply direction of the indoor unit is defined as the width of the first air guide plate. At this time, the opening angle of the first and second air guide plates is at a user- or system-set angle. For the specific functions and processing of this acquisition unit 102, please refer to step S110.

[0068] The width of the first air guide plate is the shorter side of the air guide plate, which is parallel to the airflow direction of the indoor unit and perpendicular to the rotation axis of the air guide plate. Its width is the length of the line connecting the two endpoints of the air guide plate. Figure 7 The width b of the first air guide plate in the middle.

[0069] Control unit 104 is configured to determine whether condensation occurs on the first air guide plate based on the temperature at the air outlet of the indoor unit, the indoor ambient temperature, and the indoor ambient humidity. The specific functions and processing of this control unit 104 are described in step S120.

[0070] Because the width of the first air guide plate is greater than that of the second air guide plate, the first air guide plate is closer to the indoor side, making it more prone to forming a zone of heat and cold converging. Condensation may occur on the first air guide plate but not necessarily on the second air guide plate; however, condensation on the second air guide plate will always occur on the first air guide plate. Therefore, whether or not condensation occurs on the first air guide plate is used as the criterion for judgment.

[0071] In some embodiments, the control unit 104 determines whether condensation occurs on the first air guide plate based on the temperature at the indoor unit's air outlet, the indoor ambient temperature, and the indoor ambient humidity, including:

[0072] The control unit 104 is further configured to calculate the dew point temperature based on the indoor ambient temperature and the indoor ambient humidity. The specific functions and processing of the control unit 104 are described in step S210.

[0073] The formula for calculating dew point temperature is:

[0074]

[0075] In the formula, t d t is the dew point temperature; t is the indoor ambient temperature; Φ is the indoor ambient humidity.

[0076] The control unit 104 is further configured to determine the relationship between the temperature at the indoor unit's air outlet and the dew point temperature. The specific functions and processing of this control unit 104 are described in step S220.

[0077] The control unit 104 is further configured to confirm condensation on the first air guide plate if the temperature at the indoor unit's air outlet is less than or equal to the dew point temperature. The specific functions and processing of this control unit 104 are described in step S230.

[0078] The control unit 104 is further configured to, upon determining that condensation has occurred on the first air guide plate, control the opening angle of the first air guide plate and the opening angle of the second air guide plate respectively, based on the width of the first air guide plate, so that the air blown out by the indoor unit wraps around the surface of the first air guide plate. The specific functions and processing of this control unit 104 are described in step S130.

[0079] This invention features a second air guide plate at the indoor unit's air outlet. When condensation occurs on the first air guide plate, the angle between the first and second air guide plates is controlled to direct the cold air from the indoor unit directly onto the upper and lower surfaces of the first air guide plate. This ensures the cold air completely envelops the first air guide plate, eliminating the hot and cold convergence zone. While preventing condensation on the first air guide plate, this design does not reduce the indoor fan speed or compressor frequency, maintaining a suitable cooling capacity and ensuring comfort during air conditioning use, thus enhancing the user experience.

[0080] In some embodiments, the control unit 104 controls the opening angle of the first air guide plate and the opening angle of the second air guide plate according to the width of the first air guide plate, including:

[0081] The control unit 104 is further configured to determine the included angle between the first air guide plate and the second air guide plate based on the width of the first air guide plate. The specific functions and processing of this control unit 104 are described in step S310.

[0082] like Figure 7 As shown, the angle between the first and second air guide plates is 'a'. The probability 'f' of condensation occurring at the end of the first air guide plate (the end closer to the indoor side) is related to the angle 'a' and the width 'b' of the first air guide plate. Specifically, the relationship between the condensation probability 'f' and the angle 'a' is parabolic; that is, a smaller angle 'a' results in a higher condensation probability 'f', and a larger angle 'a' also results in a higher condensation probability 'f'. Given a fixed width 'b' for the first air guide plate, whether condensation occurs at the end of the first air guide plate is determined by the angle 'a' between the air guide plates.

[0083] Specifically, the relationship between the condensation probability f and the included angle α and the width b of the first air guide plate can be expressed by a function, as follows:

[0084] f = ka 2 +tb+c;

[0085] Where k, t, and c are coefficients derived from fitting experimental test data. Using this functional relationship, given a fixed width b of the first guide vane, the angle between the second and first guide vanes when the probability of condensation at the end of the first guide vane is minimized can be determined. For example, when the width of the first guide vane is 0.91m, the angle between the two guide vanes is 2° when the probability of condensation at the end of the first guide vane is minimized, and the corresponding functional relationship is f = 2a. 2+3b+10, the calculated f = 20.7, that is, when the angle between the two air guides is 2°, the end of the first air guide is completely covered by cold air, there is no hot and cold air exchange, and condensation will not occur; for example, when the angle between the two air guides is 4°, although the end of the first air guide is also completely covered by cold air, the cold air is relatively thin, and the anti-condensation effect is slightly worse, at which point f = 44.7.

[0086] The control unit 104 is further configured to control the opening angle of the first air guide plate and the opening angle of the second air guide plate according to the included angle, so that the included angle between the first air guide plate and the second air guide plate is the included angle. The specific functions and processing of the control unit 104 are described in step S320.

[0087] By simultaneously adjusting the opening angles of the first and second air guide vanes, the angle between the two vanes is quickly brought to the angle calculated using a function relationship. This ensures that the end of the first air guide vane is completely surrounded by cold air, preventing condensation. If the air conditioner is in a set mode, such as a mode where the cold air does not blow on people or a rapid cooling mode, the angle of the first air guide vane is fixed. In this case, the opening angle of the second air guide vane can be adjusted so that the angle between the two air guide vanes is the angle calculated using a function relationship.

[0088] In some embodiments, the control unit 104 further includes: the control unit 104 is specifically configured to, when it is determined that no condensation has occurred on the first air guide plate, control the opening angle of the first air guide plate and the opening angle of the second air guide plate to the opening angle set by the user.

[0089] If it is determined that no condensation will occur on the first air guide plate, the angles of the first and second air guide plates will be returned to the user-set opening angles or the system-set angles.

[0090] Figure 8 This is a flowchart illustrating an embodiment of the air conditioning anti-condensation control method for the present invention, as shown below. Figure 8 As shown, the method for controlling condensation on the wind deflector of the present invention includes:

[0091] Step 1: After the air conditioner is turned on and the cooling mode is activated, the first and second air guide vanes at the indoor unit's air outlet are driven by two motors and opened to the set angle. The indoor fan runs at the set speed, and the compressor runs at the set frequency. At this time, the temperature at the indoor unit's air outlet and the indoor temperature and humidity are detected, and Step 2 is executed.

[0092] Step 2: Determine the current dew point temperature based on the indoor temperature and humidity, and determine whether the temperature at the indoor unit's air outlet has reached the dew point temperature; if the temperature at the indoor unit's air outlet has reached the dew point temperature, proceed to Step 3.

[0093] Step 3: Keep the indoor fan speed and compressor frequency unchanged. Control the opening angle of the first and second air guides so that the angle between the two air guides is such that condensation will not occur. Continue to determine the current dew point temperature based on the indoor temperature and humidity. Determine whether the temperature at the indoor unit's air outlet has not reached the dew point temperature. If the temperature at the indoor unit's air outlet has not reached the dew point temperature, control the opening angle of the first and second air guides to the set angle and return to Step 2 to continue execution.

[0095] The technical solution of this invention includes a first air guide plate and a second air guide plate that can swing up and down at the indoor unit of the air conditioner.
