Similarly, while performing a second-level speed adjustment on the indoor fan's current speed, the second-level speed adjustment on the indoor fan is maintained. Simultaneously, using the preset anti-condensation airflow range in the air conditioner's current operating mode as the target airflow range, at least one of the two airflow range adjustment units is activated to adjust the airflow range at the airflow location of the activated unit to the target airflow range. After a second set time, if the third set condition is met... If the current temperature difference of the air conditioner is detected to be less than a preset first allowable temperature difference, then at least one of the two air outlet range adjustment units is activated to adjust the air outlet range at the air outlet position of the activated at least one air outlet range adjustment unit to the user's desired air outlet range; the current frequency of the compressor is adjusted in the first stage to change the current air outlet temperature of the air conditioner by changing the current pipe temperature of the indoor heat exchanger, and / or the current speed of the indoor fan is adjusted in the first stage to directly change the current air outlet temperature of the air conditioner; after a sixth set time, if the current temperature difference of the air conditioner is detected to be less than the preset first allowable temperature difference for a continuous first set time, then... If the temperature difference is allowed, the compressor frequency is maintained while the compressor frequency is adjusted to the first level, and the indoor fan speed is maintained while the indoor fan speed is adjusted to the first level, and then the preset second anti-condensation mode is exited; after a sixth set time, if the current temperature difference of the air conditioner is monitored to be greater than or equal to the preset second allowable temperature difference again after a first set time, the compressor frequency is adjusted to the second level again to change the current air outlet temperature of the air conditioner by changing the current pipe temperature of the indoor heat exchanger, and / or the indoor fan speed is adjusted to the second level again to directly change the current air outlet temperature of the air conditioner;Simultaneously, using the preset anti-condensation air outlet range under the current operating mode of the air conditioner as the target air outlet range, at least one of the two air outlet range adjustment units is activated to adjust the air outlet range at the air outlet position of the activated at least one air outlet range adjustment unit to the target air outlet range; after a sixth preset time, if the current temperature difference of the air conditioner is monitored to be less than the preset first allowable temperature difference for a continuous first preset time, the current frequency of the compressor is adjusted in the first stage to change the current air outlet temperature of the air conditioner by changing the current pipe temperature of the indoor heat exchanger, and / or the current speed of the indoor fan is adjusted in the first stage to directly change the current air outlet temperature of the air conditioner; after a fifth preset time, the compressor frequency is maintained while the current frequency of the compressor is adjusted in the first stage, and the indoor fan speed is maintained while the current speed of the indoor fan is adjusted in the first stage, and then the preset second anti-condensation mode is exited.

[0015] Therefore, the solution of the present invention provides an air outlet range adjustment mechanism (i.e., a device for adjusting the air outlet range and preventing condensation) on both sides of the indoor unit's panel. Each air outlet range adjustment mechanism (i.e., a device for adjusting the air outlet range and preventing condensation) includes an air chamber, a rotating baffle, and a drive mechanism mounted on the bottom shell. An air inlet is provided on one side of the air chamber, and n air outlet channels (e.g., six outlet channels) are provided on the other side of the air chamber. The rotating baffle is located in the air chamber and can rotate within it. After the air conditioner is turned on, according to the air conditioner's operating mode, the drive mechanism is controlled to rotate the rotating baffle 6, allowing the opening and closing of the n air outlet channels to select the air outlet range of the indoor unit. In heating mode, the opening and closing of the n air outlet channels can be automatically selected or manually selected. In cooling or dehumidifying mode, when the number of open n air outlet channels is less than or equal to a set number (e.g., 3), the opening and closing of the n air outlet channels can be automatically selected or manually selected. The system controls the opening and closing of air outlets. In cooling or dehumidifying mode, when the number of open n air outlet channels exceeds a set number (e.g., 3), it determines the temperature difference between the air outlet temperature corresponding to the indoor heat exchanger tube temperature and the indoor fan speed and the air dew point temperature, based on the corresponding air outlet temperature. This determines whether the air conditioner operates in the first or second anti-condensation mode. In either mode, the air outlet temperature is changed by adjusting the compressor frequency or the indoor fan speed to ensure that the temperature difference between the air outlet temperature and the air dew point temperature is less than a preset first allowable temperature difference (e.g., 8℃), thus achieving anti-condensation control. Furthermore, by setting an air outlet range adjustment mechanism (i.e., a device for adjusting the air outlet range and anti-condensation) on both sides of the indoor unit's panel, the air outlet range on both sides of the panel is adjusted. Combined with the indoor heat exchanger tube temperature and the indoor air outlet temperature, different anti-condensation modes are operated, achieving anti-condensation control of the air conditioner, improving user experience and safety.

Detailed Implementation

[0032] 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.

[0033] Considering that condensation around the indoor unit's air outlet can drip down when it reaches a certain amount, affecting users' daily lives and posing a fire hazard, some solutions propose anti-condensation control schemes for air conditioners with top and bottom air outlets. In cooling or dehumidifying modes, these schemes control condensation by adjusting the compressor's operating frequency and electronic expansion valve opening based on different air delivery methods, set temperature, indoor ambient temperature, set fan speed, evaporator copper tube temperature, and relative humidity. This controls the evaporator surface copper tube temperature (Ttube temperature) to maintain the difference between the current air dew point temperature (Tdew point) and the evaporator tube temperature (Ttube temperature) within a reasonable range, ensuring a stable indoor temperature drop rate while preventing condensation on the indoor unit. This solution primarily focuses on addressing condensation issues when air is supplied from the top and bottom of the air outlet via the air guide plate. The anti-condensation program logic mainly revolves around coordinating anti-condensation measures with the air guide plate's top and bottom air outlets.

[0034] Some proposed air conditioner anti-condensation control schemes obtain the set temperature, fan speed, and air deflector angle when the air conditioner is running in cooling mode. Based on these parameters, they determine whether anti-condensation control conditions are met. If the conditions are met, the anti-condensation control phase begins, adjusting the air deflector angle and the indoor fan speed. However, this scheme can easily cause greater noise pollution and negatively impact user experience when the indoor fan speed is adjusted significantly.

[0035] It is evident that the solutions for condensation often involve significantly increasing the operating speed. However, this inevitably leads to a noticeable increase in noise, impacting the user's daily life and reducing their overall experience. Furthermore, increasing the speed results in increased airflow, making it easier for cold air to blow directly onto the user, creating a very unpleasant comfort experience.

[0036] Furthermore, in the relevant solutions, the air outlet of the wall-mounted indoor unit is mainly concentrated within the air guide plate's airflow range. The maximum left-right airflow range can only be increased by 25° to 30° to the left and right on top of the vertical airflow. This relatively small airflow range makes it easy for cold or hot air to blow directly on the user, affecting their comfort. A larger airflow range, on the other hand, can improve the ambient temperature more quickly and avoid the unpleasant experience caused by direct cold or hot air blowing.

[0037] Therefore, the present invention proposes an air outlet adjustment device for an air conditioner, specifically an air outlet range adjustment mechanism for an air conditioner (i.e., a device for adjusting the air outlet range and preventing condensation). The purpose is to provide a structure for adjusting the air outlet range, expanding the air outlet range, and providing a new anti-condensation logic that works in conjunction with the structure but is not entirely limited by it, including a first anti-condensation mode and a second anti-condensation mode. It is simple to operate, easy to implement, and can be quickly and widely promoted based on the air conditioner structure in related solutions without requiring major changes to the air conditioner architecture design.

[0038] According to an embodiment of the present invention, an air outlet regulating device for an air conditioner is provided. See also: Figure 1 The diagram shows a structural schematic of an embodiment of the device of the present invention. The air conditioner includes an outdoor unit and an indoor unit; the outdoor unit includes a compressor; the indoor unit includes an indoor heat exchanger and an indoor fan; the indoor unit also includes a panel 1 and a bottom shell 2; the air outlet adjustment device of the air conditioner includes: an air outlet range adjustment unit, a sampling unit, and a control unit; the number of air outlet range adjustment units is two, and the two air outlet range adjustment units are disposed on the bottom shell 2 and located on both sides of the panel 1, for adjusting the air outlet range at the air outlet positions on both sides of the panel 1 under the control of the control unit, thereby adjusting the air outlet range of the indoor unit, specifically adjusting the air outlet range of the indoor unit in heating mode, cooling mode, or dehumidification mode; in cooling mode or dehumidification mode, condensation is prevented by adjusting the air outlet range of the indoor unit.

[0039] The control unit is configured to, after the air conditioner is started and when the air outlet range of the indoor unit is allowed to be adjusted, in the current operating mode of the air conditioner, control at least one of the two air outlet range adjustment units to operate, so as to adjust the air outlet range at the air outlet position where the at least one air outlet range adjustment unit that has been operated is located, that is, to adjust the air outlet range at the air outlet position on the panel 1 where the at least one air outlet range adjustment unit is located; the current operating mode of the air conditioner is any one of heating mode, cooling mode and heating mode.

[0040] The sampling unit is used to sample the current frequency of the compressor and the current pipe temperature of the indoor heat exchanger, the current speed of the indoor fan and the current air outlet temperature of the air conditioner (i.e., the current air outlet temperature of the air conditioner at the current speed of the indoor fan) during the operation of the air conditioner when the current operating mode of the air conditioner is cooling mode or dehumidification mode, and to sample the indoor air dew point temperature of the environment where the air conditioner is located.

[0041] The control unit is further configured to, when the current operating mode of the air conditioner is cooling mode or dehumidification mode, and when the adjustment range of the air outlet range at the location of at least one activated air outlet range adjustment unit is less than or equal to a set range, adjust the current frequency of the compressor according to the current air outlet temperature of the air conditioner and the indoor air dew point temperature of the environment where the air conditioner is located, so as to change the current air outlet temperature of the air conditioner by changing the current pipe temperature of the indoor heat exchanger; and / or adjust the current speed of the indoor fan to directly change the current air outlet temperature of the air conditioner, thereby achieving anti-condensation control of the air conditioner.

[0042] The present invention employs an air outlet range adjustment mechanism (i.e., a device for adjusting the air outlet range and preventing condensation), which maximizes the expansion of the indoor unit's air outlet range and allows for flexible adjustment. While expanding the air outlet area, it ensures that cold and hot air are not directly blown on the unit, providing customers with a more comfortable airflow experience. Furthermore, a control method for adjusting the air outlet range and preventing condensation is designed, using a deep learning algorithm to optimally regulate the outlet air temperature. The air outlet range adjustment mode can be activated in heating, cooling, and dehumidification modes of the air conditioner. When the air conditioner is in cooling or dehumidification mode, the anti-condensation program setting can be activated simultaneously: in cooling or dehumidification mode, the system monitors the indoor environment's air dew point temperature, evaporator inner pipe temperature, and the outlet air temperature at different speeds of the indoor unit (such as the indoor fan speed). A deep learning algorithm is designed to adjust and control the indoor unit's outlet air temperature, comparing the indoor environment's air dew point... The system controls the operation of the air outlet range adjustment mechanism (i.e., the device used to adjust the air outlet range and prevent condensation) 5 based on the comparison between the indoor ambient air dew point temperature and the indoor unit's air outlet temperature. This avoids a sudden increase in speed during anti-condensation operation, which would cause a significant increase in noise, affecting the user's living experience and reducing user satisfaction. By adjusting the air outlet range, the indoor unit's air is directed directly from areas prone to condensation, continuously blowing out cool air and preventing the formation of hot and cold air masses in these areas. This prevents condensation from occurring at its source and improves the user experience.

[0043] In some embodiments, the two air outlet range adjustment units have identical structures; each air outlet range adjustment unit includes an air outlet range adjustment mechanism and a drive mechanism. In each air outlet range adjustment unit, the air outlet range adjustment mechanism is disposed on the bottom shell 2 and located at the air outlet position on one of the two sides of the panel 1; conversely, in two air outlet range adjustment units, both air outlet range adjustment mechanisms are disposed on the bottom shell 2 and located at the air outlet positions on both sides of the panel 1. In each air outlet range adjustment unit, the drive mechanism, under the control of the control unit, drives the air outlet range adjustment mechanism to adjust the air outlet range at the air outlet position where the air outlet range adjustment mechanism is located.

[0044] The air outlet range adjustment mechanism includes an air chamber 10 and an air duct switch. The air duct switch is located inside the air chamber 10 and can rotate or move within the air chamber 10. The air chamber 10 has an air inlet 9 and n air outlet channels, where n is a positive integer and n≥2 (e.g., n=6). The air outlet ends of the n air outlet channels cooperate with the opening positions on the corresponding sides of the panel body 1 to form the air outlet 11 of the indoor unit.

[0045] The air duct switch is activated by the drive mechanism to open or close one or more of the n air outlet ducts. When all n air outlet ducts are open, the indoor unit can achieve omnidirectional airflow within a 180-degree range. The air delivered by the indoor unit enters the air chamber 10 through the air inlet 9, then passes through one or more of the opened air outlet ducts, and finally reaches the room where the air conditioner is located via the air outlet 11 of the indoor unit.

[0046] In this invention, an air outlet range adjustment mechanism (i.e., a device for adjusting the air outlet range and preventing condensation) is designed. An air inlet and six air outlet channels are designed on both sides of the air chamber, allowing for flexible adjustment of the air outlet range. When the rotating baffle rotates one angle, the air conditioner's exhaust air can enter the air chamber through the air inlet. Due to the obstruction effect of the rotating baffle, one or more air outlets can be achieved. When the rotating baffle is fully open, the indoor unit can achieve 180-degree omnidirectional air outlet, maximizing the expansion of the indoor unit's air outlet range and allowing for flexible adjustment of the air outlet range. While expanding the air outlet area, the air volume remains constant, reducing the air volume and velocity in the direct blowing area. The uniform, larger-range air outlet can more quickly but gently lower or raise the ambient temperature. In both cold and hot air states, it avoids the unpleasant feeling of excessive cold or heat caused by direct cold or hot air blowing, providing customers with a more comfortable air outlet experience. Meanwhile, the present invention incorporates a control method for an air outlet range adjustment mechanism (i.e., a device for adjusting the air outlet range and preventing condensation) that includes a deep learning algorithm. The deep learning algorithm is used to optimally regulate the air outlet temperature, avoiding a significant increase in noise caused by a sudden increase in rotation speed during condensation prevention. Anti-condensation logic is designed to determine whether the temperature difference between the air dew point temperature and the indoor unit's air outlet temperature meets the activation conditions of the anti-condensation program. In the first anti-condensation mode, the deep learning algorithm controls the first anti-condensation operation phase. In the second anti-condensation mode, the deep learning algorithm controls the second anti-condensation operation phase, and the third anti-condensation phase adjusts the air outlet, ensuring that the indoor unit's airflow directly blows out from areas prone to condensation, continuously blowing out cool air and preventing the formation of hot and cold air convergence at these points, thus preventing condensation from occurring at its source.

[0047] The first stage (i.e., the first anti-condensation operation stage) involves fine-tuning, while the second stage (i.e., the second anti-condensation operation stage) involves aggressive adjustment, but this adjustment must be made within the range of fine-tuning. This range of fine-tuning refers to the range of frequency conversion or speed adjustments that will not cause a drastic increase in noise; see [reference needed]. Figure 12 The first and second phases. Figure 12 The second and third stages are both classified under the second anti-condensation mode.

[0048] In some embodiments, the air duct switch includes a rotary baffle 6; the drive mechanism includes a rotating shaft 7 and a stepper motor 8.

[0049] The bottom shell 2 is provided with a connecting rod 3, and a sweeping blade 4 is provided on the connecting rod 3; the air chamber 10 and the stepper motor 8 are both provided on the bottom shell 2, and the air chamber 10 is located in the area where the end of the connecting rod 3 is located.

[0050] The rotary baffle 6 and the rotating shaft 7 are both located inside the air chamber 10. The rotary baffle 6 and the stepper motor 8 are installed at both ends of the rotating shaft 7. Specifically, the rotary baffle 6 is installed at the rotating end of the rotating shaft 7, and the stepper motor 8 is installed at the driving end of the rotating shaft 7. The stepper motor 8 drives the rotating shaft 7 to rotate. When the rotating shaft 7 rotates, the rotary baffle 6 rotates accordingly to open or close one or more of the n air outlet channels.

[0051] Figure 2 This is a top view schematic diagram of an embodiment of the air outlet range adjustment mechanism (i.e., a device for adjusting the air outlet range and preventing condensation) in the indoor unit of the present invention. Figure 3 for Figure 2 A magnified side view of a portion of the structure in section C. Figure 4 This is a schematic diagram of the structure of the air outlet range adjustment mechanism (i.e., the device for adjusting the air outlet range and preventing condensation) in the indoor unit of the present invention when rotated one notch. Figure 5 This is a schematic diagram of the drive mechanism of the air outlet range adjustment mechanism (i.e., the device for adjusting the air outlet range and preventing condensation) in the indoor unit of the present invention. See also... Figures 2 to 5 In the example shown, the specific functional structure of the indoor unit in the present invention includes: an air outlet range adjustment mechanism (i.e., a device for adjusting the air outlet range and preventing condensation) 5. The air outlet range adjustment mechanism (i.e., a device for adjusting the air outlet range and preventing condensation) 5 is the main device in the indoor unit for adjusting and expanding the air outlet range, and is also an essential structural part for achieving the anti-condensation effect in the present invention. The air outlet range adjustment mechanism (i.e., a device for adjusting the air outlet range and preventing condensation) 5 is configured to cooperate with the bottom shell 2 and the panel 1, and is composed of a rotary baffle 6, a rotating shaft 7, and a stepper motor 8.

[0052] like Figure 2 As shown, a connecting rod 3 and a sweeping blade 4 are provided on the bottom shell 2 of the indoor unit. The sweeping blade 4 is mounted on the connecting rod 3, and the movement of the connecting rod 3 can drive the sweeping blade 4 to sweep the air. There are multiple sweeping blades 4, which are spaced apart on the connecting rod 3. The air outlet range adjustment mechanism (i.e., the device for adjusting the air outlet range and preventing condensation) 5 is also provided on the bottom shell 2 of the indoor unit and is located in the area where the end of the connecting rod 3 is located. Furthermore, the device for adjusting the air outlet range and preventing condensation 5 is located on both sides of the panel 1 of the indoor unit.

[0053] Since the air outlet is located in the middle of the panel 1 of the indoor unit, the areas on both sides of the panel 1 are prone to heat exchange, resulting in condensation on both sides of the panel 1. Therefore, in the solution of this invention, an air outlet range adjustment mechanism (i.e., a device for adjusting the air outlet range and preventing condensation) 5 is designed on both sides of the panel 1 to efficiently adjust the air outlet. By adjusting the air outlet range, the air from the indoor unit is blown directly out from the area where condensation is prone to occur, avoiding the formation of heat exchange and preventing condensation from the source, thus improving the user experience.

[0054] In some embodiments, the interior space of the air chamber 10 is in the shape of a semi-fan to serve as the rotation space for the rotating baffle 6, so that the rotating baffle 6 can rotate in the interior space of the air chamber 10 and avoid interference with the bottom shell 2; in the interior space of the air chamber 10, the n air outlet channels extend from the semi-fan-shaped end of the semi-fan shape.

[0055] In some embodiments, a rotating groove is provided in the internal space of the air chamber 10 at the location of the air inlet 9 of the air chamber 10; the rotating shaft 7 is fixedly disposed in the rotating groove; the bottom surface of the rotating groove is lower than the bottom surface of the air chamber 10 to limit the rotation of the rotating shaft 7.

[0056] like Figure 3 and Figure 4 As shown, a wind chamber 10 is designed on the bottom shell 2. A rotary baffle 6 and a rotating shaft 7 are installed in the wind chamber 10, and a stepper motor 8 is installed in conjunction with the rotating shaft 7. The wind chamber 10, the rotary baffle 6, the rotating shaft 7, the stepper motor 8, and the panel 1 together form an air outlet range adjustment mechanism (i.e., a device for adjusting the air outlet range and preventing condensation) 5. The wind chamber 10 is located on both sides of the bottom shell 2, in a semi-fan shape, to accommodate the rotation space design of the rotary baffle 6. Six air outlet channels extend from the front end of the semi-fan shape. Figure 3 The six air outlet channels extending from the front end of the semi-fan-shaped structure shown are designed as straight cylinders. The air outlet ends of the six air outlet channels are matched with the opening positions of the panel 1 to form the air outlets on both sides of the indoor unit. The stepper motor 8 and the rotating shaft 7 are mounted on the bottom shell 2. A rotating groove for fixing the rotating shaft 7 is provided at the air inlet position of the air chamber 10, and the bottom surface of the rotating groove is lower than the bottom surface of the air chamber 10 to limit the rotation of the rotating shaft 7.

[0057] In some embodiments, m protrusions are provided on the rotating shaft 7, and m concave blocks are correspondingly provided on the rotating baffle 6 at positions that cooperate with the rotating shaft 7. The m protrusions and m concave blocks are installed together so that the rotating shaft 7 rotates and drives the rotating baffle 6 to rotate. m is a positive integer (e.g., m = 3).

[0058] like Figure 5 As shown, three protrusions are designed on the rotating shaft 7, and three concave blocks are designed on the rotating baffle 6 at the position where it mates with the rotating shaft 7. The mate between the protrusions and concave blocks serves to drive the rotating baffle 6 to rotate when the rotating shaft 7 is rotated. This structural design is only one of the designs. Other structural designs that can achieve the above two functions are all within the scope expressed by the present invention. In order to avoid possible structural interference between the rotating baffle 6 and the bottom shell 2 during rotation, part of the rotating baffle 6 is cut off at the position near the inner side of the wind chamber 10.

[0059] The location of the rotating baffle 6 near the inner side of the air chamber 10 can be found in [reference needed]. Figure 5 The rotating baffle 6 shown is positioned at its end, where it mates with the rotating shaft. When the rotating baffle 6 rotates, it rotates around its axis towards the inside of the air chamber. The side of the rotating baffle 6 closest to the inside of the air chamber, where it mates with the rotating shaft, will inevitably interfere with the rotating baffle during rotation. Only by cutting off a portion can interference between the rotating baffle 6 and the bottom shell 2 be avoided after rotation. This is only to prevent interference between the rotating baffle 6 and the bottom shell 2 during rotation; of course, other methods to avoid interference between the rotating baffle 6 and the bottom shell 2 during rotation are also acceptable.

[0060] in addition, Figure 5 The drive mechanism of the air outlet range adjustment mechanism (i.e., the device used to adjust the air outlet range and prevent condensation) 5 shown is designed to meet ventilation requirements, but other opening designs can also be adopted. For example, it involves opening the rotary baffle 6. At the front end position when the rotary baffle 6 is closed, teeth are provided on the upper and lower sides, or only on the upper and lower sides, to engage with the arc-shaped rack a. The side of rack a near the air outlet engages with the front teeth of the rotary baffle 6 when it is closed. Then, at the other end of the arc-shaped rack, it meshes with another gear b. The motor drives gear b to move the arc-shaped rack a and the engaged rotary baffle 6, which can also achieve the purpose of opening the rotary baffle 6.

[0061] Combination Figure 4 In the example shown, the air outlet range adjustment mechanism (i.e., the device for adjusting the air outlet range and preventing condensation) 5 can be controlled by the stepper motor 8 to rotate the shaft 7 and the rotary baffle 6 by a certain angle. Six air outlet structures are designed within the air chamber 10, having one air inlet 9 and six air outlets 11; the air chamber 10, the air inlet 9, and the six air outlets 11 together constitute the air inlet and outlet structure of the indoor unit. The air inlet 9 of the air chamber 10 is connected to the air outlet of the indoor unit, meaning that the air delivered from the air outlet of the indoor unit enters the air chamber 10 through the air inlet 9, and is then delivered to the room through the air outlets opened in the six air outlets 11 of the air chamber 10. When the air outlet range adjustment mechanism (i.e., the device for adjusting the air outlet range and preventing condensation) 5 is controlled by the stepper motor 8 to rotate the shaft 7 and the rotary baffle 6 by one angle, such as... Figure 4 As shown, the air conditioner can enter the air chamber 10 through the air inlet 9. Due to the blocking effect of the rotating baffle 6, air can be discharged in one compartment. When the rotating baffle 6 is fully opened, the indoor unit can achieve 180-degree all-round air discharge, that is, the indoor unit can achieve 180-degree all-round air discharge. Compared to related solutions where the indoor unit's air-sweeping blades 4, driven by the connecting rod 3, can only achieve a small airflow swing, with the maximum left and right sweeping range limited to an increase of only 25° to 30° from the vertical airflow, resulting in a small airflow range and the potential for direct cold or hot air blowing, thus affecting user comfort, the airflow range adjustment mechanism 5 designed in this invention (i.e., a device for adjusting the airflow range and preventing condensation) can maximize the expansion of the indoor unit's airflow range and flexibly adjust it. While expanding the indoor unit's airflow area, the airflow volume remains constant, while the airflow and velocity in the direct blowing area decrease. Furthermore, the uniform and larger airflow range can more quickly but gently lower or raise the ambient temperature. In both cold and hot air states, it can avoid the unpleasant feeling of excessive cold or heat caused by direct cold or hot air blowing, providing customers with a more comfortable airflow experience.

[0062] Condensation mainly occurs at the air outlets of the indoor unit, specifically at the air guide vanes and the sides of the panel 1 near the air outlet. The sides of the panel 1 near the air outlet are particularly prone to heat exchange. When the air outlet temperature is lower than the ambient dew point temperature, especially during low-fan operation, this heat exchange leads to condensation. Similarly, in high-humidity environments, when the air outlet temperature is close to the dew point, heat exchange also causes condensation. This invention addresses this by incorporating an air outlet range adjustment mechanism (i.e., a device for adjusting the air outlet range and preventing condensation) 5 on both sides of the panel 1. By adjusting the air outlet range of the six air outlets 11, the air from the indoor unit is directed directly from areas prone to condensation, ensuring a continuous flow of cool air. This guarantees that only cool air is blown out at these locations, preventing heat exchange and thus eliminating condensation at its source.

[0063] The technical solution of this invention involves providing an air outlet range adjustment mechanism (i.e., a device for adjusting the air outlet range and preventing condensation) 5 on both sides of the panel 1 of the indoor unit. Each air outlet range adjustment mechanism (i.e., a device for adjusting the air outlet range and preventing condensation) 5 includes: an air chamber 10 mounted on the bottom shell, a rotary baffle 6, and a drive mechanism (such as a drive mechanism composed of a rotating shaft 7 and a stepper motor 8). An air inlet is provided on one side of the air chamber 10, and n air outlet channels (such as six outlet channels) are provided on the other side of the air chamber 10. The rotary baffle 6 is located in the air chamber 10 and can rotate within it. After the air conditioner is turned on, depending on the air conditioner's operating mode, the rotary baffle 6 can be rotated by controlling the drive mechanism to select the opening and closing of n air outlet channels to rotate the air outlet range of the indoor unit. In heating mode, the opening and closing of n air outlet channels can be automatically selected or manually selected. In cooling or dehumidifying mode, when the number of open n air outlet channels is less than or equal to the set number (e.g., 3), the opening and closing of n air outlet channels can be automatically selected. The opening and closing of n air outlet channels can also be manually selected. In cooling or dehumidifying mode, when the number of n air outlet channels open is greater than the set number (e.g., 3), the temperature difference between the air outlet temperature corresponding to the indoor heat exchanger tube temperature and the indoor fan speed and the air dew point temperature is determined based on the air outlet temperature corresponding to the indoor heat exchanger tube temperature and the indoor fan speed. This determines whether the air conditioner should operate in the first anti-condensation mode or the second anti-condensation mode. In the first or second anti-condensation mode, the air outlet temperature of the air conditioner is changed by adjusting the compressor frequency or the indoor fan speed so that the temperature difference between the air outlet temperature and the air dew point temperature is less than the preset first allowable temperature difference (e.g., 8℃), thus achieving anti-condensation control. Therefore, by setting an air outlet range adjustment mechanism (i.e., a device for adjusting the air outlet range and anti-condensation) 5 on both sides of the indoor unit panel 1, the air outlet range on both sides of the indoor unit panel 1 is adjusted, and different anti-condensation modes are operated in combination with the indoor heat exchanger tube temperature and the indoor air outlet temperature, thus achieving anti-condensation control of the air conditioner, improving user experience and safety.

[0064] According to an embodiment of the present invention, an air conditioner corresponding to an air outlet regulating device for an air conditioner is also provided. This air conditioner may include: the air outlet regulating device for an air conditioner as described above.

[0065] Since the processing and functions implemented by the air conditioner in this embodiment are basically corresponding to the embodiments, principles and examples of the device, any details not covered in the description of this embodiment can be found in the relevant descriptions in the foregoing embodiments, and will not be repeated here.

[0066] The technical solution of this invention involves setting an air outlet range adjustment mechanism (i.e., a device for adjusting the air outlet range and preventing condensation) 5 on both sides of the panel 1 of the indoor unit. Each air outlet range adjustment mechanism (i.e., a device for adjusting the air outlet range and preventing condensation) 5 includes: an air chamber 10, a rotary baffle 6, and a drive mechanism (such as a drive mechanism composed of a rotating shaft 7 and a stepper motor 8) on the bottom shell. An air inlet is provided on one side of the air chamber 10, and n air outlet channels (such as six outlet channels) are provided on the other side of the air chamber 10. The rotary baffle 6 is located in the air chamber 10 and can rotate in the air chamber 10. After the air conditioner is turned on, according to the operating mode of the air conditioner, the rotary baffle 6 can be rotated by controlling the drive mechanism to select the opening and closing of the n air outlet channels to rotate the air outlet range of the indoor unit. In the heating mode, the opening and closing of the n air outlet channels can be automatically selected or manually selected. In the cooling mode or dehumidification mode, the number of opening n air outlet channels is less than or equal to a set number. When the number of air outlets is greater than the set number (e.g., 3), the system can automatically select the opening and closing of n air outlet channels or allow manual selection of n air outlet channels. In cooling or dehumidifying mode, if the number of open n air outlet channels is greater than the set number (e.g., 3), the system determines the temperature difference between the air outlet temperature corresponding to the indoor heat exchanger tube temperature and the indoor fan speed and the air dew point temperature. This determines whether the air conditioner should operate in the first anti-condensation mode or the second anti-condensation mode. In either the first or second anti-condensation mode, the system adjusts the compressor frequency or the indoor fan speed to change the air outlet temperature, ensuring that the temperature difference between the air outlet temperature and the air dew point temperature is less than the preset first allowable temperature difference (e.g., 8℃), thus achieving anti-condensation control. The system adaptively optimizes the air outlet temperature of the indoor unit by using compressor frequency conversion or fine-tuning the speed, avoiding a sudden increase in speed during anti-condensation operation that could lead to a significant increase in noise, affecting the user's living experience and reducing user satisfaction.

[0067] According to embodiments of the present invention, a control method for an air outlet regulating device corresponding to an air conditioner is also provided, such as... Figure 6 The diagram shows a flowchart of an embodiment of the method of the present invention. The control method of the air outlet regulating device of the air conditioner may include steps S110 to S130.

[0068] In step S110, after the air conditioner is started and the air outlet range of the indoor unit is allowed to be adjusted, in the current operating mode of the air conditioner, at least one of the two air outlet range adjustment units is controlled to operate, so as to adjust the air outlet range at the air outlet position where the at least one air outlet range adjustment unit that has been operated is located, that is, to adjust the air outlet range at the air outlet position on the panel 1 where the at least one air outlet range adjustment unit is located; the current operating mode of the air conditioner is any one of the heating mode, cooling mode and heating mode.

[0069] In some embodiments, the specific process of controlling at least one of the two air outlet range adjustment units to operate in the current operating mode of the air conditioner in step S110 is described in the following exemplary description.

[0070] The following is combined with Figure 7 The schematic diagram shown is a flowchart of an embodiment of the method of the present invention in which at least one of the two air outlet range adjustment units is controlled to operate after the air conditioner is started. The specific process of controlling at least one of the two air outlet range adjustment units to operate after the air conditioner is started in step S110 is further explained, including steps S210 to S230.

[0071] Step S210: If the current operating mode of the air conditioner is any one of heating mode, cooling mode, and heating mode, determine whether a user's air outlet range adjustment command has been received; wherein, the air outlet range adjustment command is an adjustment command corresponding to the user's required air outlet range.

[0072] Step S220: If an air outlet range adjustment command is received from the user, then according to the air outlet range adjustment command, control at least one of the two air outlet range adjustment units to operate, so as to adjust the air outlet range at the air outlet position where the at least one activated air outlet range adjustment unit is located to the user's required air outlet range, that is, adjust the air outlet range at the air outlet position on the panel body 1 where the at least one activated air outlet range adjustment unit is located to the user's required air outlet range.

[0073] In some implementations, step S220, controlling at least one of the two air outlet range adjustment units to operate according to the air outlet range adjustment command, includes: if the current air outlet mode of the indoor unit is direct air outlet, then simultaneous operation of both air outlet range adjustment units is allowed; if the current air outlet mode of the indoor unit is oscillating angle air outlet, then the air outlet range of the air outlet range adjustment unit located on the side opposite to the sweeping blade 4 of the indoor unit is not allowed to be adjusted above the set air outlet range. The set air outlet range may be, for example, the air outlet range corresponding to 3 divisions.

[0074] Step S230: If no air outlet range adjustment command is received from the user, then the preset comfort air outlet range in the current operating mode of the air conditioner is used as the target air outlet range. At least one of the two air outlet range adjustment units is controlled to operate, so as to adjust the air outlet range at the air outlet position of the at least one activated air outlet range adjustment unit to the target air outlet range. That is, the air outlet range at the air outlet position on the panel 1 where the at least one activated air outlet range adjustment unit is located is adjusted to the target air outlet range. The preset comfort air outlet range is an empirical value determined in advance based on the current operating parameters of the air conditioner. The current operating parameters of the air conditioner include at least one of the following: the current fan speed of the indoor fan, the current air outlet temperature of the indoor fan, the current stationary position of the air guide plate of the indoor unit, and the current sweeping angle of the indoor fan.

[0075] Figure 11 This is a schematic diagram illustrating the process of adjusting the air outlet range mechanism (i.e., the device for adjusting the air outlet range and preventing condensation) in the indoor unit of the present invention in heating mode. Figure 11 As shown, the process of adjusting the air outlet range adjustment mechanism (i.e., the device used to adjust the air outlet range and prevent condensation) in the indoor unit to adjust the air outlet range mode in heating mode includes:

[0076] Step 11: After the air conditioner is turned on, when the user selects the heating mode, the air conditioner controller automatically switches to the heating mode operating condition 1. There is no condensation problem in the heating mode. This operating condition 1 allows the user to remotely select the number of settings of the air outlet range adjustment mechanism (i.e., the device used to adjust the air outlet range and prevent condensation) 5 via the remote control to adjust the air outlet range of the air outlet range adjustment mechanism (i.e., the device used to adjust the air outlet range and prevent condensation) 5, and then proceed to step 12.

[0077] In heating mode, the program control includes a division adjustment program. Users can select numbers 1 to 6 or the automatic option using the remote control. By default, the air outlet range adjustment mechanism (the device used to adjust the air outlet range and prevent condensation) 5 is not activated when no selection is made. When any number from 1 to 6 is selected, such as 3, the air outlet range adjustment mechanism 5 will activate three divisions of airflow. When direct airflow is emitted, both left and right air outlet range adjustment mechanisms 5 can operate simultaneously. When swivel airflow, the air outlet range adjustment mechanism 5 on the side with the sweeping blades 4 is not allowed to be activated more than three divisions; activating too many divisions on that side will affect the desired left and right airflow effect.

[0078] Step 12: After the air conditioner is turned on, when the user selects the heating mode and the automatic adjustment mode is selected, the air outlet range adjustment mechanism (i.e., the device used to adjust the air outlet range and prevent condensation) 5 will run the factory preset command obtained from the comfort test. This preset command is the optimal control scheme after collecting experimental data for different fan speeds, different temperatures, fixed positions of the air guides and the sweeping angle. It can automatically judge the current air conditioner operating conditions (including fan speed, ambient temperature, fixed position of the air guides, etc.) to run the air outlet range adjustment mechanism (i.e., the device used to adjust the air outlet range and prevent condensation) 5.

[0079] Figure 12 This is a schematic diagram illustrating the process of adjusting the air outlet range adjustment mechanism (i.e., the device for adjusting the air outlet range and preventing condensation) in the indoor unit of the present invention, in cooling or dehumidification mode, to adjust the air outlet range mode and the anti-condensation mode. Figure 12 As shown, the process of adjusting the air outlet range adjustment mechanism (i.e., the device used to adjust the air outlet range and anti-condensation mode) in the indoor unit during cooling or dehumidification mode includes:

[0080] Step 21: When the air conditioner is in cooling or dehumidifying mode, the program control includes a division adjustment program. The user can use the remote control to select a number from 1 to 6 or the automatic option. By default, the air outlet range adjustment mechanism (i.e., the device used to adjust the air outlet range and prevent condensation) 5 is not activated when no selection is made. When any number from 1 to 6 is selected, for example, selecting the number 3, the air outlet range adjustment mechanism (i.e., the device used to adjust the air outlet range and prevent condensation) 5 will activate three divisions of air outlet. When direct airflow is emitted, the air outlet range adjustment mechanisms (i.e., the devices used to adjust the air outlet range and prevent condensation) 5 on both the left and right sides can operate simultaneously. When swivel airflow, the air outlet range adjustment mechanism (i.e., the device used to adjust the air outlet range and prevent condensation) 5 on the side with the sweeping blades 4 is not allowed to be activated to more than three divisions. Activating too many divisions on that side will affect the desired left and right airflow effect.

[0081] When the automatic adjustment mode is selected, the air outlet range adjustment mechanism (i.e., the device used to adjust the air outlet range and prevent condensation) 5 will run the factory preset command obtained from the comfort test. This preset command is the optimal control scheme after collecting experimental data for different fan speeds, different temperatures, fixed positions of the air guides and the sweeping angle. It can automatically determine the current air conditioner operating conditions (including fan speed, ambient temperature, fixed positions of the air guides, etc.) to run the air outlet range adjustment mechanism (i.e., the device used to adjust the air outlet range and prevent condensation) 5, and then execute step 22.

[0082] In step S120, when the current operating mode of the air conditioner is cooling mode or dehumidification mode, during the operation of the air conditioner, the current frequency of the compressor and the current pipe temperature of the indoor heat exchanger are sampled, the current speed of the indoor fan and the current air outlet temperature of the air conditioner are sampled (i.e., the current air outlet temperature of the air conditioner at the current speed of the indoor fan is sampled), and the indoor air dew point temperature of the environment where the air conditioner is located is sampled.

[0083] In step S130, when the current operating mode of the air conditioner is cooling mode or dehumidification mode, if the adjustment range of the air outlet range at the location of at least one activated air outlet range adjustment unit is less than or equal to the set range, the current frequency of the compressor is adjusted according to the current air outlet temperature of the air conditioner and the indoor air dew point temperature of the environment where the air conditioner is located, so as to change the current air outlet temperature of the air conditioner by changing the current pipe temperature of the indoor heat exchanger; and / or the current speed of the indoor fan is adjusted to directly change the current air outlet temperature of the air conditioner, thereby realizing the anti-condensation control of the air conditioner.

[0084] The solution of this invention adopts an air outlet range adjustment mechanism (i.e. a device for adjusting the air outlet range and preventing condensation), which maximizes the expansion of the air outlet range of the indoor unit and allows for flexible adjustment of the air outlet range. While expanding the air outlet area, it ensures that cold and hot air are not blown directly, bringing customers a more comfortable air outlet experience. Furthermore, the aforementioned air outlet range adjustment mechanism (i.e., the device for adjusting the air outlet range and preventing condensation) 5 is controlled. The control method includes: the mode for adjusting the air outlet range can be activated in the heating mode, cooling mode, and dehumidification mode of the air conditioner; when the air conditioner is in cooling mode or dehumidification mode, the anti-condensation program setting can be activated simultaneously; in cooling mode or dehumidification mode, the air dew point temperature of the indoor environment, the evaporator inner pipe temperature, and the air outlet temperature at different speeds of the indoor unit (such as the speed of the indoor fan) are monitored, a deep learning algorithm is designed to adjust and control the air outlet temperature of the indoor unit, the air dew point temperature of the indoor environment is compared with the air outlet temperature of the indoor unit, and the operation of the air outlet range adjustment mechanism (i.e., the device for adjusting the air outlet range and preventing condensation) 5 is controlled according to the comparison between the air dew point temperature of the indoor environment and the air outlet temperature of the indoor unit.

[0085] In this invention, regardless of whether it's a fixed-frequency or variable-frequency air conditioner, the evaporator's inner pipe temperature and the indoor unit's outlet air temperature at different speeds can be collected before the air conditioner leaves the factory. After summarizing the correlation between these two, a deep learning algorithm is designed and embedded into the anti-condensation control module. Alternatively, the deep learning algorithm can be designed directly without pre-shipment data collection. Then, by collecting data from the user's actual operating conditions, the outlet air temperature of the indoor unit is adaptively and optimally controlled through compressor frequency conversion or fine-tuning of the compressor speed. This avoids a sudden increase in speed during anti-condensation operations, which would cause a significant increase in noise and negatively impact the user's experience. The deep learning algorithm designed based on the correlation between the evaporator's inner pipe temperature and the indoor unit's outlet air temperature at different speeds aims to meet functional requirements; however, other fuzzy control algorithms can also be used instead.

[0086] In some embodiments, in step S130, when the current operating mode of the air conditioner is cooling mode or dehumidification mode, if the adjustment range of the air outlet range at the location of at least one activated air outlet range adjustment unit is less than or equal to the set range, the current frequency of the compressor is adjusted according to the current air outlet temperature of the air conditioner and the indoor air dew point temperature of the environment where the air conditioner is located, so as to change the current air outlet temperature of the air conditioner by changing the current pipe temperature of the indoor heat exchanger; and / or the current speed of the indoor fan is adjusted to directly change the current air outlet temperature of the air conditioner, including: a first adjustment process for changing the current air outlet temperature of the air conditioner.

[0087] The following is combined with Figure 8The schematic diagram shown is an embodiment of the first adjustment process of changing the current air outlet temperature of the air conditioner in the method of the present invention. It further illustrates the specific process of the first adjustment process of changing the current air outlet temperature of the air conditioner in step S130, including steps S310 to S370.

[0088] Step S310: When the current operating mode of the air conditioner is cooling mode or dehumidification mode, if the adjustment range of the air outlet range at the location of at least one activated air outlet range adjustment unit is less than or equal to the set range, the current temperature difference between the indoor air dew point temperature of the environment where the air conditioner is located and the current air outlet temperature of the air conditioner is determined and recorded as the current temperature difference of the air conditioner.

[0089] Step S320: Determine the relationship between the current temperature difference of the air conditioner and the preset first allowable temperature difference and the preset second allowable temperature difference; wherein the preset first allowable temperature difference is less than the preset second allowable temperature difference, the preset first allowable temperature difference is, for example, 8°C, and the preset second allowable temperature difference is, for example, 10°C.

[0090] Step S330: If the current temperature difference of the air conditioner is less than the preset first allowable temperature difference, then control the air conditioner to maintain its current operation, without controlling the air outlet range adjustment unit or performing anti-condensation control.

[0091] Step S340: If the current temperature difference of the air conditioner is monitored to be greater than or equal to a preset first allowable temperature difference and less than a preset second allowable temperature difference for a continuous first set time, then a preset first anti-condensation mode is activated. In the preset first anti-condensation mode, the current frequency of the compressor is adjusted to a first level to change the current air outlet temperature of the air conditioner by changing the current pipe temperature of the indoor heat exchanger, and / or the current speed of the indoor fan is adjusted to a first level to directly change the current air outlet temperature of the air conditioner. The first set time is, for example, 45 seconds.

[0092] Step S350: After the second set time, if the current temperature difference of the air conditioner is monitored to be less than the preset first allowable temperature difference for a continuous third set time, then the compressor frequency is restored while performing a first-level frequency adjustment on the current frequency of the compressor, and the indoor fan speed is restored while performing a first-level speed adjustment on the current speed of the indoor fan. The second set time is, for example, 10 minutes, and the third set time is, for example, 90 seconds.

[0093] Step S360: After restoring the compressor frequency while performing a first-level frequency adjustment on the current frequency of the compressor, and restoring the indoor fan speed while performing a first-level speed adjustment on the current speed of the indoor fan, if the current temperature difference of the air conditioner is continuously monitored to be less than a preset first allowable temperature difference for a first set time within a fourth set time, the preset first anti-condensation mode is exited. Then, according to the air outlet range adjustment command, at least one of the two air outlet range adjustment units is controlled to operate. The fourth set time is, for example, 30 minutes.

[0094] Step S370: After restoring the compressor frequency while performing a first-level frequency adjustment on the current frequency of the compressor, and restoring the indoor fan speed while performing a first-level speed adjustment on the current speed of the indoor fan, if, within a fourth set time period, the current temperature difference of the air conditioner is again monitored to be greater than or equal to a preset first allowable temperature difference and less than a preset second allowable temperature difference for a continuous first set time period, then the compressor's current frequency is adjusted again to change the air conditioner's current outlet air temperature by changing the current pipe temperature of the indoor heat exchanger, and / or the indoor fan's current speed is adjusted again to directly change the air conditioner's current outlet air temperature. Air outlet temperature; after adjusting the compressor's current frequency to change the air conditioner's current air outlet temperature by altering the indoor heat exchanger's current pipe temperature, and / or adjusting the indoor fan's current speed to directly change the air conditioner's current air outlet temperature, until the air conditioner's current temperature difference is continuously monitored for a first set time within a fourth set time period and is found to be less than a preset first allowable temperature difference, the compressor's frequency is maintained while adjusting the compressor's current frequency to the first set time, and the indoor fan's speed is maintained while adjusting the indoor fan's current speed to the first set time, and then the preset first anti-condensation mode is exited.

[0095] like Figure 12 As shown, the process of adjusting the air outlet range adjustment mechanism (i.e., the device used to adjust the air outlet range and anti-condensation mode) in the indoor unit during cooling or dehumidification mode also includes:

[0096] Step 22: In actual operation, when the air conditioner is in cooling mode or dehumidification mode, the ambient temperature sensor will obtain the dew point temperature of the indoor air, the evaporator temperature sensor will obtain the temperature of the evaporator inner tube, and at the same time, an air outlet temperature sensor will be added at the air outlet to obtain the air outlet temperature at different speeds of the indoor unit. In the solution of this invention, regardless of whether it is a fixed-frequency air conditioner or a variable-frequency air conditioner, the evaporator inner pipe temperature and the indoor unit outlet air temperature at different speeds are collected in advance before the air conditioner leaves the factory. The evaporator inner pipe temperature and the indoor unit outlet air temperature at different speeds are also re-determined by adjusting the compressor frequency or the indoor unit speed. The corresponding rules between the evaporator inner pipe temperature and the indoor unit outlet air temperature at the current speed under different adjustment methods are summarized. A deep learning algorithm is designed. This algorithm can quickly calculate the air dew point temperature of the indoor environment and analyze the real-time collected current evaporator inner pipe temperature and the outlet air temperature at the current indoor unit speed. When the temperature difference between the air dew point temperature and the indoor unit outlet air temperature deviates from the first allowable temperature difference preset before leaving the factory within 8°C and lasts for 45 seconds, the algorithm will quickly determine and give a response scheme to adjust the compressor frequency or fine-tune the indoor unit speed.

[0097] Specifically, whether to adjust the current frequency of the compressor or the current speed of the indoor fan is determined based on the current frequency of the compressor, the current pipe temperature of the indoor heat exchanger, the current speed of the indoor fan, the current air outlet temperature of the air conditioner (i.e., sampling the current air outlet temperature of the air conditioner at the current speed of the indoor fan), and the range of the indoor air dew point temperature of the environment where the air conditioner is located. See the example below for details.

[0098] For example, assuming the air conditioning cooling and dehumidification scenario is an ambient temperature (i.e., dry bulb temperature) above 26℃, the current evaporator inner tube temperature is X℃, the air outlet temperature at the current indoor unit speed W is Y℃, and the air dew point temperature is Z℃, the algorithm will quickly determine that the current operating condition can be changed by finely adjusting the indoor unit speed W±v (where v is the allowable fine-tuning range, which can be determined based on the actual air conditioning operating condition) to make the temperature difference between the air dew point temperature and the indoor unit's air outlet temperature greater than the first allowable temperature difference preset at the factory by 8℃, so as to achieve the purpose of preventing condensation. For example, assuming the air conditioner is used for cooling and dehumidifying in an environment where the ambient temperature (i.e., dry bulb temperature) is above 26℃, the current indoor unit speed W is 1050 RPM, the current evaporator inner tube temperature X is 8℃, the outlet air temperature Y is 10℃, the air dew point temperature Z is 19℃, and the difference between the air dew point temperature and the outlet air temperature is 9℃ (i.e., the current temperature difference of the air conditioner) which is greater than 8℃ (i.e., the preset first allowable temperature difference). At this time, the difference between the current evaporator inner tube temperature and the outlet air temperature is 2℃, which is relatively close. By increasing the speed by 50 RPM, the current speed is increased to 1100 RPM, which achieves a rapid increase in outlet air temperature and meets the anti-condensation requirements. For example, if the current evaporator inner tube temperature is 0℃, the outlet air temperature at the current indoor unit speed P is Q℃, and the air dew point temperature is R℃, the algorithm will quickly determine that the current operating condition can be changed by adjusting the compressor frequency converter to alter the indoor unit's outlet air temperature. This will ensure that the temperature difference between the air dew point temperature and the indoor unit's outlet air temperature is greater than the factory-preset first allowable temperature difference of 8℃, thus achieving the purpose of preventing condensation. For instance, assuming the air conditioning cooling and dehumidification scenario is an ambient temperature (i.e., dry bulb temperature) above 26℃, the current indoor unit speed P is 1350 RPM, the current evaporator inner tube temperature O is 9℃, the outlet air temperature Q is 13℃, and the air dew point temperature R is 22℃, the difference between the air dew point temperature and the outlet air temperature is greater than 8℃. In this case, the difference between the current evaporator inner tube temperature and the outlet air temperature is 4℃. By adjusting the compressor frequency converter, the current compressor frequency is reduced, the evaporator tube temperature increases, the speed remains unchanged, and the outlet air temperature increases, thus meeting the anti-condensation requirements. The algorithm is embedded into the anti-condensation control module, and deep learning is performed by collecting data from the user's actual operating conditions. The air outlet temperature is optimally controlled by the compressor frequency conversion or fine-tuning of the speed. This is the first anti-condensation mode. Alternatively, the deep learning algorithm can be designed directly without collecting data before leaving the factory.

[0099] Furthermore, when the air conditioner is in cooling or dehumidifying mode, if the monitoring system detects that the customer has set the air outlet range adjustment mechanism (i.e., the device used to adjust the air outlet range and prevent condensation) to more than 3 out of 5 bars, the anti-condensation control will not be activated. If the monitoring system detects that the customer has set the air outlet range adjustment mechanism (i.e., the device used to adjust the air outlet range and prevent condensation) to less than or equal to 3 out of 5 bars, the system will compare the real-time indoor air dew point temperature with the indoor unit's air outlet temperature to obtain the temperature difference between the air dew point temperature and the indoor unit's air outlet temperature. Then, the obtained temperature difference will be compared with the factory-preset first allowable temperature difference value. If it is less than the factory-preset first allowable temperature difference value of 8°C, then there is no need to adjust the indoor unit's air outlet temperature and set the anti-condensation function. After that, the corresponding steps in steps 23, 24, and 25 will be selectively executed.

[0100] Step 23, First Stage: If the temperature difference obtained for 45 seconds is greater than or equal to the preset first allowable temperature difference of 8℃ but less than the preset second allowable temperature difference of 10℃, the air conditioner enters the anti-condensation control mode based on the current operating status of the indoor unit. In this mode, it will first run the first anti-condensation mode according to the current fan speed of the indoor unit, changing the outlet air temperature through the first stage compressor frequency conversion or the first stage fine-tuning speed. If, after running for 10 minutes, the condition of being less than the preset first allowable temperature difference of 8℃ is met, and the requirement is met again after 90 seconds of monitoring, the compressor frequency or indoor unit speed will be restored. After 30 minutes of monitoring, the first stage will be exited. In the anti-condensation mode, the air outlet range adjustment mechanism (i.e., the device used to adjust the air outlet range and prevent condensation) 5 can only be used to adjust the air outlet range according to the customer's settings. When the compressor frequency or indoor unit speed is restored, if the temperature difference obtained after 45 seconds of continuous monitoring within 30 minutes is greater than or equal to the preset first allowable temperature difference of 8℃ but less than the preset second allowable temperature difference of 10℃, the air outlet temperature will be changed again through the first-stage compressor frequency conversion or the first-stage fine-tuning speed. After the second adjustment, the original compressor frequency or indoor unit speed will not be restored. After 30 minutes of continuous monitoring and meeting the requirements, the first anti-condensation mode will be exited, but the compressor frequency or indoor unit speed will remain unchanged. In the first anti-condensation mode, fine-tuning is used. Whether it is gentle or aggressive fine-tuning, it is within the fine-tuning range, and the adjustment range is not allowed to be too large, which will cause a sharp increase in noise.

[0101] In some embodiments, in step S130, when the current operating mode of the air conditioner is cooling mode or dehumidification mode, if the adjustment range of the air outlet range at the location of at least one activated air outlet range adjustment unit is less than or equal to the set range, the current frequency of the compressor is adjusted according to the current air outlet temperature of the air conditioner and the indoor air dew point temperature of the environment where the air conditioner is located, so as to change the current air outlet temperature of the air conditioner by changing the current pipe temperature of the indoor heat exchanger; and / or the current speed of the indoor fan is adjusted to directly change the current air outlet temperature of the air conditioner, further comprising: a second adjustment process for changing the current air outlet temperature of the air conditioner.

[0102] The following is combined with Figure 9 The schematic diagram shown is an embodiment of the second adjustment process of changing the current air outlet temperature of the air conditioner in the method of the present invention. It further illustrates the specific process of the second adjustment process of changing the current air outlet temperature of the air conditioner in step S130, including steps S410 to S450.

[0103] Step S410: When the current operating mode of the air conditioner is cooling mode or dehumidification mode, if the adjustment range of the air outlet range at the location of at least one activated air outlet range adjustment unit is less than or equal to a set range, determine the current temperature difference between the indoor air dew point temperature of the environment where the air conditioner is located and the current air outlet temperature of the air conditioner, and record it as the current temperature difference of the air conditioner; after determining the relationship between the current temperature difference of the air conditioner and the preset first allowable temperature difference and the preset second allowable temperature difference, if the air conditioner is continuously monitored for a first set time... If the current temperature difference is greater than or equal to a preset second allowable temperature difference, then a preset second anti-condensation mode is activated. In this mode, the compressor's current frequency is adjusted in a second stage to change the air conditioner's current outlet temperature by altering the current pipe temperature of the indoor heat exchanger, and / or the indoor fan's current speed is adjusted in a second stage to directly change the air conditioner's current outlet temperature. The adjustment range of the second-stage frequency adjustment is greater than that of the first-stage frequency adjustment, and the adjustment range of the second-stage speed adjustment is greater than that of the first-stage speed adjustment. The first set time is, for example, 45 seconds.

[0104] Step S420: After the second set time, if the current temperature difference of the air conditioner is monitored to be less than the preset first allowable temperature difference for a continuous third set time, then the compressor frequency is restored while performing a second-level frequency adjustment on the current frequency of the compressor, and the indoor fan speed is restored while performing a second-level speed adjustment on the current speed of the indoor fan. The second set time is, for example, 10 minutes, and the third set time is, for example, 90 seconds.

[0105] Step S430: After restoring the compressor frequency while performing a second-level frequency adjustment on the current frequency of the compressor, and restoring the indoor fan speed while performing a second-level speed adjustment on the current speed of the indoor fan, if the current temperature difference of the air conditioner is continuously monitored to be less than a preset first allowable temperature difference for a first set time within a fourth set time, then the preset second anti-condensation mode is exited, and at least one of the two air outlet range adjustment units is controlled to operate according to the air outlet range adjustment command. The fourth set time is, for example, 30 minutes.

[0106] Step S440: After restoring the compressor frequency while performing a second-level frequency adjustment on the current frequency of the compressor, and restoring the indoor fan speed while performing a second-level speed adjustment on the current speed of the indoor fan, if the current temperature difference of the air conditioner is monitored to be greater than or equal to the preset second allowable temperature difference again for a first set time within a fourth set time, then the current frequency of the compressor is adjusted again to change the current air outlet temperature of the air conditioner by changing the current pipe temperature of the indoor heat exchanger, and / or the current speed of the indoor fan is adjusted again to directly change the current air outlet temperature of the air conditioner.

[0107] Step S450: After adjusting the current frequency of the compressor to a second level to change the current air outlet temperature of the air conditioner by changing the current pipe temperature of the indoor heat exchanger, and / or adjusting the current speed of the indoor fan to a second level to directly change the current air outlet temperature of the air conditioner, if the current temperature difference of the air conditioner is monitored to be less than the preset first allowable temperature difference for a continuous first set time within a fourth set time, then the current frequency of the compressor is adjusted to a first level to change the current air outlet temperature of the air conditioner by changing the current pipe temperature of the indoor heat exchanger, and / or the current speed of the indoor fan is adjusted to a first level to directly change the current air outlet temperature of the air conditioner; after a fifth set time, the compressor frequency is maintained while the current frequency of the compressor is adjusted to a first level, and the indoor fan speed is maintained while the current speed of the indoor fan is adjusted to a first level, and then the preset second anti-condensation mode is exited. The fifth setting time, such as the time interval during step 24 when the first-stage compressor frequency conversion or the first-stage fine-tuning speed changes the outlet air temperature to maintain the compressor frequency or indoor unit speed no longer changes and exits the second anti-condensation mode, can be 5s to 10s.

[0108] like Figure 12As shown, the process of adjusting the air outlet range adjustment mechanism (i.e., the device used to adjust the air outlet range and anti-condensation mode) in the indoor unit during cooling or dehumidification mode further includes: Step 24, the second stage, if the temperature difference obtained for 45 seconds is greater than or equal to the preset second allowable temperature difference of 10℃, then the outlet temperature is changed by using the aggressive second-stage compressor frequency conversion or the second-stage fine-tuning speed (i.e., the adjustment range is increased). If, after running for 10 minutes, the condition of less than the preset first allowable temperature difference of 8℃ is met, and the condition is met for another 90 seconds, the compressor frequency or indoor unit speed is restored. When the condition is met for another 30 minutes, the condition is restored. Afterwards, the second anti-condensation mode is exited. The air outlet range adjustment mechanism (i.e., the device used to adjust the air outlet range and prevent condensation) 5 can only be used to adjust the air outlet range according to the customer's settings. When the compressor frequency or indoor unit speed is restored, if the temperature difference obtained after 45 seconds of continuous monitoring within 30 minutes is greater than or equal to the preset second allowable temperature difference of 10℃, the air outlet temperature is changed again by the second-stage compressor frequency conversion or the second-stage fine-tuning speed. After monitoring continues for 30 minutes and the requirements are met, the air outlet temperature is changed by the first-stage compressor frequency conversion or the first-stage fine-tuning speed. Then, the compressor frequency or indoor unit speed is kept unchanged, and the second anti-condensation mode is exited. At this time, the first-stage compressor frequency conversion or the first-stage fine-tuning speed is the first-stage adjustment action. After the adjustment, this action will not be changed again, and the mode will exit directly without any other time interval. That is, the anti-condensation mode is exited immediately after the adjustment. The purpose of adjusting to the first-stage compressor frequency conversion or the first-stage fine-tuning speed before exiting is also to reduce the possibility of condensation recurring.

[0109] In some embodiments, when the current operating mode of the air conditioner is cooling mode or dehumidification mode, if the adjustment range of the air outlet range at the location of at least one activated air outlet range adjustment unit is less than or equal to a set range, the current frequency of the compressor is adjusted according to the current air outlet temperature of the air conditioner and the indoor air dew point temperature of the environment where the air conditioner is located, so as to change the current air outlet temperature of the air conditioner by changing the current pipe temperature of the indoor heat exchanger; and / or the current speed of the indoor fan is adjusted to directly change the current air outlet temperature of the air conditioner, and further includes a third adjustment process for changing the current air outlet temperature of the air conditioner.

[0110] The following is combined Figure 10 The schematic diagram shown is an embodiment of the second adjustment process of changing the current air outlet temperature of the air conditioner in the method of the present invention. It further illustrates the specific process of the second adjustment process of changing the current air outlet temperature of the air conditioner in step S130, including steps S510 to S550.

[0111] Step S510: When the current operating mode of the air conditioner is cooling mode or dehumidification mode, if the adjustment range of the air outlet range at the location of at least one activated air outlet range adjustment unit is less than or equal to a set range, determine the current temperature difference between the indoor air dew point temperature of the environment where the air conditioner is located and the current air outlet temperature of the air conditioner, and record it as the current temperature difference of the air conditioner; after determining the relationship between the current temperature difference of the air conditioner and the preset first allowable temperature difference and the preset second allowable temperature difference, if the air conditioner is continuously monitored for a first set time... If the current temperature difference is greater than or equal to a preset second allowable temperature difference, then a preset second anti-condensation mode is activated. In this mode, the compressor's current frequency is adjusted in a second stage to change the air conditioner's current outlet temperature by altering the current pipe temperature of the indoor heat exchanger, and / or the indoor fan's current speed is adjusted in a second stage to directly change the air conditioner's current outlet temperature. The adjustment range of the second-stage frequency adjustment is greater than that of the first-stage frequency adjustment, and the adjustment range of the second-stage speed adjustment is greater than that of the first-stage speed adjustment. The first set time is, for example, 45 seconds.

[0112] Step S520: After the second set time, if the current temperature difference of the air conditioner is still not less than the preset first allowable temperature difference, then while performing a second-level frequency adjustment on the current frequency of the compressor, the second-level frequency adjustment on the current frequency of the compressor is maintained, and while performing a second-level speed adjustment on the current speed of the indoor fan, the second-level speed adjustment on the current speed of the indoor fan is maintained. At the same time, taking the preset anti-condensation air outlet range in the current operating mode of the air conditioner as the target air outlet range, at least one of the two air outlet range adjustment units is controlled to operate, so as to adjust the air outlet range at the air outlet position where the at least one activated air outlet range adjustment unit is located to the target air outlet range, that is, to adjust the air outlet range at the air outlet position on the panel 1 where the at least one activated air outlet range adjustment unit is located to the target air outlet range.

[0113] In step S530, after a second set time, if the current temperature difference of the air conditioner is monitored to be less than the preset first allowable temperature difference for a third set time, then at least one of the two air outlet range adjustment units is controlled to operate, so as to adjust the air outlet range at the air outlet position of the at least one activated air outlet range adjustment unit to the user's required air outlet range; the current frequency of the compressor is adjusted in the first stage to change the current air outlet temperature of the air conditioner by changing the current pipe temperature of the indoor heat exchanger, and / or the current speed of the indoor fan is adjusted in the first stage to directly change the current air outlet temperature of the air conditioner.

[0114] Step S540: After the sixth set time, if the current temperature difference of the air conditioner is monitored to be less than the preset first allowable temperature difference for a continuous first set time, then the compressor frequency is maintained while performing a first-level frequency adjustment on the current frequency of the compressor, and the indoor fan speed is maintained while performing a first-level speed adjustment on the current speed of the indoor fan, and then the preset second anti-condensation mode is exited. The sixth set time is, for example, 20 minutes.

[0115] Step S550: After the sixth set time, if the current temperature difference of the air conditioner is monitored to be greater than or equal to the preset second allowable temperature difference again for the first set time, then the current frequency of the compressor is adjusted again to change the current air outlet temperature of the air conditioner by changing the current pipe temperature of the indoor heat exchanger, and / or the current speed of the indoor fan is adjusted again to directly change the current air outlet temperature of the air conditioner; at the same time, the preset anti-condensation air outlet range in the current operating mode of the air conditioner is used as the target air outlet range, and at least one of the two air outlet range adjustment units is controlled to operate to adjust the air outlet range at the air outlet position of the at least one activated air outlet range adjustment unit to the target air outlet range, that is, to adjust the air outlet range of the at least one activated air outlet range adjustment unit to the target air outlet range. The air outlet range at the air outlet position on the panel 1 where the air outlet range adjustment unit is located is adjusted to the target air outlet range; after a sixth set time, if the current temperature difference of the air conditioner is monitored to be less than the preset first allowable temperature difference for a continuous first set time, the current frequency of the compressor is adjusted to the first level to change the current air outlet temperature of the air conditioner by changing the current pipe temperature of the indoor heat exchanger, and / or the current speed of the indoor fan is adjusted to the first level to directly change the current air outlet temperature of the air conditioner; after a fifth set time, the compressor frequency is maintained while the current frequency of the compressor is adjusted to the first level, and the indoor fan speed is maintained while the current speed of the indoor fan is adjusted to the first level, and then the preset second anti-condensation mode is exited.

[0116] like Figure 12As shown, the process of adjusting the air outlet range adjustment mechanism (i.e., the device used to adjust the air outlet range and prevent condensation) in the indoor unit to adjust the air outlet range mode and the anti-condensation mode in cooling or dehumidification mode also includes: Step 25, the third stage, if the temperature difference obtained for 45 seconds is greater than or equal to the preset second allowable temperature difference of 10℃, and the outlet temperature is changed by aggressively using the second-stage compressor frequency conversion or the second-stage fine-tuning speed (i.e., increasing the adjustment range), after running for 10 minutes, it still cannot meet the condition of being less than the preset first allowable temperature difference of 8℃, while maintaining the second-stage compressor frequency conversion or the second-stage fine-tuning speed to change the outlet temperature, the rotary baffle 6 is rotated to the specified number of divisions through program judgment, so that the air outlet of the area prone to condensation opens to air out, thereby avoiding the generation of condensation; if after running for 10 minutes, the condition of being less than the preset first allowable temperature difference of 8℃ is met, and after continuing to monitor for 90 seconds and meeting the requirements, the rotary baffle 6 is returned to the customer-specified number of divisions, and the first-stage compressor frequency conversion or The first stage fine-tuning speed changes the outlet air temperature. After monitoring for 20 minutes and meeting the requirements, the second anti-condensation program exits, but the first stage compressor frequency or the first stage indoor unit speed remains unchanged. If, after running for 10 minutes, the temperature difference is less than the preset first allowable temperature difference of 8℃, and after monitoring for 90 seconds and meeting the requirements, the rotary baffle 6 is moved back to the customer-specified number of divisions. The first stage compressor frequency conversion or the first stage fine-tuning speed changes the outlet air temperature. If, during continued monitoring within 20 minutes, the temperature difference obtained for 45 seconds is again greater than or equal to the preset second allowable temperature difference of 10℃, then the second stage compressor frequency conversion or the second stage fine-tuning speed (i.e., the adjustment range is increased) is used again to change the outlet air temperature. The program determines and controls the rotary baffle 6 to rotate to the specified number of divisions. After monitoring for 20 minutes and meeting the requirements, the first stage compressor frequency conversion or the first stage fine-tuning speed changes the outlet air temperature, and the rotary baffle 6 is no longer moved back to the customer-specified number of divisions, thus exiting the second anti-condensation mode.

[0117] The grid settings involved in the present invention, such as the preset first allowable temperature difference of 8°C, the preset second allowable temperature difference of 10°C, the monitoring time of 90s, the running time of 5s to 10s, the running time of 10min, and the monitoring time of 20min, are all for specific air conditioning scenarios. In actual applications, they can be flexibly adjusted according to the actual experimental verification data based on different indoor unit models, specifications, and usage environments.

[0118] The present invention also provides a control device, comprising: a start-up module for activating an air outlet range adjustment mechanism (i.e., a device for adjusting the air outlet range and preventing condensation) 5 when the air conditioner is in heating mode, cooling mode, or dehumidification mode; a temperature monitoring module for monitoring and acquiring the indoor air dew point temperature, evaporator inner pipe temperature, and indoor unit air outlet temperature in cooling mode or dehumidification mode; and an algorithm control module for adaptively and optimally controlling the air outlet temperature by means of compressor frequency conversion or fine-tuning speed, and for comparing the indoor air dew point temperature with the indoor unit air outlet temperature, and controlling the operation of the anti-condensation device based on the comparison of temperature differences.

[0119] Since the processing and functions implemented by the method in this embodiment are basically the same as the aforementioned embodiments, principles and examples of air conditioners, any details not covered in this embodiment can be found in the relevant descriptions in the aforementioned embodiments, and will not be repeated here.

[0120] The technical solution of this embodiment involves setting an air outlet range adjustment mechanism (i.e., a device for adjusting the air outlet range and preventing condensation) 5 on both sides of the panel 1 of the indoor unit. Each air outlet range adjustment mechanism (i.e., a device for adjusting the air outlet range and preventing condensation) 5 includes: an air chamber 10, a rotary baffle 6, and a drive mechanism (such as a drive mechanism composed of a rotating shaft 7 and a stepper motor 8) on the bottom shell. An air inlet is provided on one side of the air chamber 10, and n air outlet channels (such as six outlet channels) are provided on the other side of the air chamber 10. The rotary baffle 6 is located in the air chamber 10 and can rotate in the air chamber 10. After the air conditioner is turned on, according to the operating mode of the air conditioner, the rotary baffle 6 can be rotated by controlling the drive mechanism to select the opening and closing of the n air outlet channels to rotate the air outlet range of the indoor unit. In the heating mode, the opening and closing of the n air outlet channels can be automatically selected or manually selected. In the cooling mode or dehumidification mode, the number of opening n air outlet channels is less than or equal to When a set quantity (e.g., 3) is set, the opening and closing of n air outlet channels can be selected automatically or manually. In cooling or dehumidifying mode, if the number of open n air outlet channels is greater than the set quantity (e.g., 3), the air outlet temperature corresponding to the indoor heat exchanger tube temperature and indoor fan speed is determined. The temperature difference between the air outlet temperature corresponding to the indoor fan speed and the air dew point temperature is then determined to decide whether the air conditioner should operate in the first anti-condensation mode or the second anti-condensation mode. In either the first or second anti-condensation mode, the air outlet temperature is changed by adjusting the compressor frequency or the indoor fan speed to ensure that the temperature difference between the air outlet temperature and the air dew point temperature is less than the preset first allowable temperature difference (e.g., 8℃), thus achieving anti-condensation control. By adjusting the air outlet range, the indoor unit blows air directly from areas prone to condensation, continuously blowing out cool air and avoiding the formation of hot and cold air convergence at these points, preventing condensation from the source and improving the user experience.
