Therefore, when the operation mode of the air conditioner and the temperature of the indoor heat exchanger meet the cold wind prevention condition, the method controls the air sweeping angle of the air guide mechanism according to the air supply area of ​​the air guide mechanism, thereby reducing the cold wind blowing directly to the human body, achieving a better cold wind prevention effect, and improving the user experience.

[0026] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0027] The following describes a method for controlling an air guide mechanism of an air conditioner, a control device for an air guide mechanism of an air conditioner, a computer-readable storage medium, and an air conditioner according to an embodiment of the present invention with reference to the accompanying drawings.

[0028] Figure 1 Flow chart of a method for controlling an air guide mechanism of an air conditioner according to some embodiments of the present invention.

[0029] like Figure 1 As shown, the control method of the air guide mechanism of the air conditioner according to the embodiment of the present invention may include the following steps:

[0030] S1, obtaining the operating mode of the air conditioner.

[0031] Specifically, the operation mode of the air conditioner generally includes cooling operation, heating operation, defrosting operation, dehumidification operation, cold wind protection operation, etc. During the operation of the air conditioner, the current operation mode will be displayed on the display panel of the air conditioner. Therefore, the operation mode of the air conditioner can be obtained by checking the display panel of the air conditioner; or, the current operation mode of the air conditioner can be obtained through the operation mode displayed on the air conditioner wire controller; or, when the mobile terminal is connected to the air conditioner, the current operation mode of the air conditioner can be obtained through the operation mode displayed on the mobile terminal; or, the current operation mode of the air conditioner can be determined by obtaining some operation parameters of the air conditioner, such as the temperature of the indoor heat exchanger, etc. It should be noted that the method of obtaining the operation mode of the air conditioner is not limited to the several methods described in the above embodiments, and can also include other existing methods or methods that may appear in the future, which are not limited here.

[0032] S2, determining an air supply area of ​​the air guide mechanism, wherein the air guide mechanism includes a plurality of air supply areas.

[0033] Specifically, the air supply area of ​​the air guide mechanism can be determined according to the installation position of the indoor unit of the air conditioner. For example, when the air conditioner is a household air conditioner, the indoor unit is installed in the room. At this time, the air supply area can be the upper half of the room, the lower half of the room, the left side of the room, the right side of the room, etc. In some embodiments of the present invention, the air supply area refers to the area where the air is delivered to the room by the air guide mechanism, and the specific structure and air supply direction of the air guide mechanism are not limited. Therefore, by setting multiple air supply areas, it is convenient to adjust the angle of air supply and better realize the cold wind prevention control.

[0034] S3, when the operation mode of the air conditioner and the temperature of the indoor heat exchanger meet the cold wind protection condition, the air sweeping angle of the air guide mechanism is controlled according to the air supply area of ​​the air guide mechanism.

[0035] Specifically, according to the operating mode of the air conditioner, it is determined whether to enter the cold wind prevention control mode. For example, when the operating mode of the air conditioner has just started heating for a period of time, the temperature of the wind blown out is relatively low, and the cold wind prevention control mode can be entered at this time; for another example, when the air conditioner is running in the heating mode and receives a shutdown command, the waste heat of the indoor heat exchanger will slowly decrease, and the temperature of the wind blown out will gradually decrease, and the cold wind prevention control mode can be entered at this time; for another example, when the air conditioner is running in the heating mode, when it is determined according to the operating parameters of the air conditioner that the defrost mode needs to be entered, since the defrost mode is equivalent to cooling operation, the temperature of the wind blown into the room will gradually decrease, and the cold wind prevention control mode can be entered at this time.

[0036] After entering the cold wind prevention control mode according to the operation mode of the air conditioner, it is also determined whether to execute the cold wind prevention control according to the temperature of the indoor heat exchanger. For example, when the temperature of the indoor heat exchanger is greater than the set value, it is considered that the cold wind prevention condition is met, and the cold wind prevention control logic is performed. At this time, according to the air supply area of ​​the air guide mechanism, the air guide angle corresponding to the air supply area can be obtained, and the air guide mechanism is controlled according to the air sweeping angle corresponding to the air supply area.

[0037] Taking the air supply area including the upper half wind sweeping area and the lower half wind sweeping area as an example, for the upper half wind sweeping area, it is not easy to blow to the user, and the wind sweeping angle of the air guide mechanism can be adjusted upwards to control the wind sweeping between the set minimum wind sweeping angle and the maximum wind sweeping angle, such as the minimum wind sweeping angle is flush with the horizontal direction, and the maximum wind sweeping angle is the position where the wind sweeps toward the roof, so that the cold air blown out by the air conditioner is blown upwards, and then spread throughout the room, thereby avoiding the cold air from blowing directly toward the human body. For the lower half wind sweeping area, it is easy to blow to the user, and the wind sweeping angle of the air guide mechanism can be adjusted downwards, and the wind sweeping angle can be a very small range, near the position where the wind blows toward the ground against the wall, or it can be a fixed wind sweeping angle blowing toward the ground, so that the cold air blown out by the air conditioner is blown downwards against the wall, and then spread throughout the room, thereby avoiding the cold air from blowing directly toward the human body. For another example, if there are multiple air supply areas, then in the farther air supply areas, a larger angle can be set to increase the coverage of the air supply, and in the closer air supply areas, the wind sweeping angle can be appropriately reduced to avoid the direct blowing effect.

[0038] In the above embodiment, when the operating mode of the air conditioner and the temperature of the indoor heat exchanger meet the conditions for preventing cold wind, the wind sweeping angle of the air guide mechanism is controlled according to the air supply area of ​​the air guide mechanism, thereby reducing the cold wind blowing directly onto the human body, achieving a better cold wind prevention effect, and improving the user experience.

[0039] In some embodiments of the present invention, the operation mode of the air conditioner that meets the cold wind prevention condition may include: the air conditioner is operated in a heating and blowing residual heat operation mode; or the air conditioner is operated in a heating mode for a first preset time; or the air conditioner is operated in a heating and defrosting operation mode. The first preset time can be calibrated according to actual conditions.

[0040] That is to say, the operation mode of the air conditioner must meet any one of the following conditions: operation in the heating blowing residual heat operation mode, operation in the heating mode for the first preset time, or operation in the heating defrosting operation mode, in order to meet the cold wind prevention condition. This is the air conditioner operating in the heating blowing residual heat mode. After the air conditioner starts the heating mode, when the indoor temperature approaches or reaches the preset temperature, the air conditioner will reduce the heat output and switch to a blowing residual heat mode. During this process, the air conditioner may blow cold air directly to the human body. Similarly, when the air conditioner starts heating for the first time, the indoor temperature is usually low, and the air conditioner needs to run for a period of time to increase the indoor temperature. The air conditioner runs in the heating mode for the first preset time. During this process, the air conditioner may also blow cold air directly to the human body. During the heating process, if the outdoor temperature is too low, the outdoor unit of the air conditioner may affect its normal operation due to the formation of frost, and heating defrosting treatment is required. The air conditioner will switch to the defrosting mode, stop heating and heat the outdoor unit to melt the frost to restore the normal heat exchange effect. During this process, the air conditioner may also blow cold air directly to the human body. For this reason, the anti-cold wind mode can only be performed when the operating mode of the air conditioner meets the conditions for anti-cold wind control.

[0041] In some embodiments of the present invention, when the air supply area of ​​the air guide mechanism includes the first air supply area, the indoor heat exchanger temperature satisfies the cold wind protection condition including: the temperature difference between the indoor heat exchanger temperature and the first preset heat exchanger temperature is greater than or equal to the first preset temperature, and lasts for the second preset time; or the temperature difference between the indoor heat exchanger temperature and the first preset heat exchanger temperature is greater than or equal to the second preset temperature, wherein the first preset temperature is greater than the second preset temperature, and the first preset heat exchanger temperature, the first preset temperature, the second preset temperature and the second preset time can be calibrated according to actual conditions. For example, the first preset heat exchanger temperature can be 26°C, the first preset temperature can be 2°C, the second preset temperature can be 0°C, and the second preset time can be 60s.

[0042] Specifically, the air supply area of ​​the air guide mechanism of the air conditioner has multiple air supply areas. When the air supply area of ​​the air guide mechanism includes the first air supply area, it is necessary to further determine whether the temperature of the indoor heat exchanger meets the cold wind protection condition. The temperature of the indoor heat exchanger is obtained by setting a temperature sensor on one side of the indoor heat exchanger, recording the initial temperature and observing the temperature change to determine how fast the indoor heat exchanger temperature drops, wherein the temperature of the indoor heat exchanger includes: one of the coil temperature, outlet temperature and inlet temperature. Considering that the cooling speed of the indoor heat exchanger is inconsistent under different outdoor ambient temperatures, different conditions are set to determine whether the cold wind protection condition is met.

[0043] When the temperature of the indoor heat exchanger drops slowly, the air conditioner will not enter the cold wind prevention control for a long time, which will cause the cold wind to blow directly to the human body. At this time, in order to avoid the cold wind blowing directly to the human body, it is necessary to increase the time limit so that the indoor heat exchanger can work fully. That is to say, when the temperature difference between the indoor heat exchanger temperature and the first preset heat exchanger temperature (such as 26°C) is greater than or equal to the first preset temperature (such as 2°C), and the duration is the second preset time (such as 60s), it is considered that the indoor heat exchanger meets the cold wind prevention condition at this time. When the indoor heat exchanger temperature drops quickly, if the temperature difference between the indoor heat exchanger temperature and the first preset heat exchanger temperature is greater than or equal to the second preset temperature (such as 0°C), it is considered that the indoor heat exchanger meets the cold wind prevention condition at this time, and the air guide mechanism of the air conditioner will quickly perform the cold wind prevention control. It should be noted that the first preset temperature is greater than the second preset temperature. The temperature settings of the first preset heat exchanger temperature, the first preset temperature and the second preset temperature in the above embodiments are not used as limitations to the present invention. In other embodiments, the temperature settings can be changed.

[0044] In some embodiments of the present invention, the wind sweeping angle of the air guide mechanism is controlled, including: determining a first cold wind protection angle of the first air supply area; when a wind sweeping instruction is received, controlling the air guide mechanism to sweep air within the range between the first cold wind protection angle and the upper limit angle of the air guide mechanism; when no wind sweeping instruction is received, controlling the wind sweeping direction of the air guide mechanism to be at the first cold wind protection angle.

[0045] Specifically, when the air supply area of ​​the air guide mechanism includes the first air supply area, the air sweeping angle of the air guide mechanism is controlled. It is necessary to first determine the first cold wind protection angle of the first air supply area, and then control the air sweeping angle of the air guide mechanism according to the air sweeping instruction. For example, the first cold wind protection angle can be determined by adjusting the angle of the air guide plate in the air guide mechanism, and the approximate cold wind protection direction can be determined according to the human body position, the room layout and the position where the air conditioner is set. Then, the angle of the air guide plate is adjusted by rotating, pushing or moving the air guide plate, and the adjustment is made according to the real-time situation to achieve the required first cold wind protection angle. The user can send a sweeping instruction through a wire controller or a mobile terminal. After the air conditioner receives the sweeping instruction, according to the determined first cold wind protection angle, the air guide mechanism of the air conditioner is controlled to sweep the air within the first cold wind protection angle and the upper limit angle of the air guide mechanism, so that the cold wind blows upward, avoiding the cold wind blowing directly on the human body; when the air conditioner does not receive the sweeping instruction, according to the determined first cold wind protection angle, the sweeping direction of the air guide mechanism is directly controlled at the first cold wind protection angle to achieve the effect of cold wind protection.

[0046] It should be noted that those skilled in the art can set the first cold wind protection angle according to actual conditions, and the upper limit angle of the air guide mechanism can be the upper limit value of the angle that can be allowed to swing. The embodiment of the present invention does not limit the specific value of the first cold wind protection angle.

[0047] In some embodiments of the present invention, when the air supply area of ​​the air guide mechanism includes a second air supply area, the indoor heat exchanger temperature satisfies the cold wind protection condition including: the temperature difference between the indoor heat exchanger temperature and the second preset heat exchanger temperature is greater than or equal to the third preset temperature, and lasts for the third preset time; or the temperature difference between the indoor heat exchanger temperature and the second preset heat exchanger temperature is greater than or equal to the fourth preset temperature, wherein the third preset temperature is greater than the fourth preset temperature, and the second preset heat exchanger temperature, the third preset temperature, the fourth preset temperature and the third preset time can be calibrated according to actual conditions. For example, the second preset heat exchanger temperature can be 28°C, the third preset temperature can be 2°C, the fourth preset temperature can be 0°C, and the third preset time can be 30s.

[0048] Specifically, there are multiple air supply areas of the air guide mechanism of the air conditioner. When the air supply area of ​​the air guide mechanism includes the second air supply area, it is necessary to further determine whether the temperature of the indoor heat exchanger meets the condition of preventing cold wind. When the temperature of the indoor heat exchanger drops slowly, the air conditioner will not enter the cold wind prevention control for a long time, which will cause the cold wind to blow directly to the human body. At this time, in order to avoid the cold wind blowing directly to the human body, it is necessary to increase the time limit so that the indoor heat exchanger can work fully. That is to say, when the temperature difference between the indoor heat exchanger temperature and the second preset heat exchanger temperature (such as 28°C) is greater than or equal to the third preset temperature (such as 2°C), and the duration is the third preset time (such as 30s), it is considered that the indoor heat exchanger meets the cold wind prevention condition. When the indoor heat exchanger temperature drops quickly, if the temperature difference between the indoor heat exchanger temperature and the second preset heat exchanger temperature is greater than or equal to the fourth preset temperature (such as 0°C), it is considered that the indoor heat exchanger meets the cold wind prevention condition, and the air guide mechanism of the air conditioner will quickly perform the cold wind prevention control.

[0049] It should be noted that the third preset temperature is greater than the fourth preset temperature. The temperature settings of the second preset heat exchanger temperature, the third preset temperature and the fourth preset temperature in the above embodiment are not intended to limit the present invention. In other embodiments, the temperature settings may be changed.

[0050] In some embodiments of the present invention, the wind sweeping angle of the air guide mechanism is controlled, including: determining a second cold wind protection angle of the second air supply area; and controlling the wind sweeping direction of the air guide mechanism to be at the second cold wind protection angle.

[0051] Specifically, when the air supply area of ​​the air guide mechanism includes the second air supply area, the air sweeping angle of the air guide mechanism is controlled. It is necessary to first determine the second cold wind protection angle of the second air supply area, and then control the air sweeping angle of the air guide mechanism. For example, the second cold wind protection angle can be determined by adjusting the angle of the air guide plate in the air guide mechanism, and the approximate cold wind protection direction is determined according to the human body position, the room layout and the position of the air conditioner. Then, the angle of the air guide plate is adjusted by rotating, pushing or moving the air guide plate, and the adjustment is made according to the real-time situation to achieve the required second cold wind protection angle. When determining the second cold wind protection angle, according to the determined second cold wind protection angle, the air guide mechanism is directly controlled to stop the swinging action, and the sweeping direction is controlled to be at the second cold wind protection angle, so that the wind is blown against the wall and avoids blowing directly to the human body. Since the second air supply area in the embodiment of the present invention is the lower sweeping half area, and the wind in the lower sweeping half area is more likely to blow directly to the human body, the air guide mechanism is directly controlled to stop the swinging action to avoid the cold wind blowing directly to the human body.

[0052] It should be noted that those skilled in the art can set the second cold wind protection angle according to actual conditions, and the embodiment of the present invention does not limit the specific value of the second cold wind protection angle.

[0053] In some embodiments of the present invention, the above method also includes: when the operating mode of the air conditioner or the temperature of the indoor heat exchanger does not meet the cold wind protection condition, controlling the wind sweeping angle of the air guide mechanism according to a preset control logic.

[0054] That is to say, when the operation mode of the air conditioner is not any one of the heating and blowing residual heat operation mode, the heating mode operation for the first preset time, or the heating and defrosting operation mode, that is, the operation mode of the air conditioner does not meet the cold wind prevention condition, the cold wind prevention control of the air guide mechanism of the air conditioner will not be entered. In other words, when the air supply area of ​​the air guide mechanism includes the first air supply area, the indoor heat exchanger temperature does not meet the temperature difference between the indoor heat exchanger temperature and the first preset heat exchanger temperature, which is greater than or equal to the first preset temperature and lasts for the second preset time, or the temperature difference between the indoor heat exchanger temperature and the first preset heat exchanger temperature is greater than or equal to the second preset temperature. When the air supply area of ​​the air guide mechanism includes the second air supply area, the indoor heat exchanger temperature does not meet the temperature difference between the indoor heat exchanger temperature and the second preset heat exchanger temperature, which is greater than or equal to the third preset temperature and lasts for the third preset time, or the temperature difference between the indoor heat exchanger temperature and the second preset heat exchanger temperature is greater than or equal to the fourth preset temperature. At this time, the temperature of the indoor heat exchanger does not meet the cold wind prevention condition, and the wind sweeping angle of the air guide mechanism can be controlled according to the preset control logic to exit the cold wind prevention control of the air guide mechanism of the air conditioner. It should be noted that the preset control logic in the above embodiment is a control logic determined according to the operating parameters of the air conditioner or the mode set by the user.

[0055] As a specific embodiment of the present invention, Figure 2 As shown, the control method of the air guide mechanism of the air conditioner may include the following steps:

[0056] S101, obtaining the operating mode of the air conditioner.

[0068] It should be noted that the specific numerical values ​​mentioned above are only used as examples to illustrate the embodiments of the present invention in detail, and should not be understood as limiting the present invention. In other examples or implementations or embodiments, other numerical values ​​can be selected according to the present invention, and are not specifically limited here.

[0069] In summary, according to the control method of the air guide mechanism of the air conditioner according to the embodiment of the present invention, the operation mode of the air conditioner is obtained, and the air supply area of ​​the air guide mechanism is determined, wherein the air guide mechanism includes multiple air supply areas, and when the operation mode of the air conditioner and the temperature of the indoor heat exchanger meet the cold wind protection condition, the air sweeping angle of the air guide mechanism is controlled according to the air supply area of ​​the air guide mechanism. Therefore, when the operation mode of the air conditioner and the temperature of the indoor heat exchanger meet the cold wind protection condition, the method controls the air sweeping angle of the air guide mechanism according to the air supply area of ​​the air guide mechanism, thereby reducing the cold wind blowing directly to the human body, achieving a better cold wind protection effect, and improving the user experience.

[0070] Corresponding to the above-mentioned embodiment, the embodiment of the present invention further proposes a control device for the air guide mechanism of an air conditioner.

[0072] The acquisition module 110 is used to acquire the operation mode of the air conditioner. The determination module 120 is used to determine the air supply area of ​​the air guide mechanism, wherein the air guide mechanism includes multiple air supply areas.
