Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to a method for preventing panel condensation and an air conditioner. Background Art

[0002] Currently, some air conditioners on the market are equipped with panel air ducts, which are surrounded by the inner surface of the panel and the middle frame.

[0003] When this type of air conditioner is in cooling mode or dehumidification mode, there is long-term airflow in the panel air duct, resulting in a huge temperature difference between the inner and outer surfaces of the panel. Condensation is very likely to form on the inner surface of the panel. After the condensation gathers, it drips from the air outlet, seriously affecting the user experience. Summary of the Invention

[0004] The problem solved by the present invention is that condensation is easily generated on the panel of the existing air conditioner, which affects the user experience.

[0005] In order to solve the above problems, the present invention provides an air conditioner, which can prevent condensation on the panel and improve user experience.

[0006] The embodiment of the present invention provides a technical solution:

[0007] 20. The heat dissipation controller of claim 19, wherein the air conditioner further comprises a cover for the cooling fan and a cover for the cooling fan, wherein the cover has a first end for cooling the cooling fan and a second end for cooling the cooling fan. The cover has a first end for cooling the cooling fan and a second end for cooling the cooling fan. The cover has a second end for cooling the cooling fan and a cover for cooling the cooling fan.

[0008] Obtaining an operating mode of the air conditioner;

[0009] If the operating mode is cooling mode or dehumidification mode, obtaining the air outlet mode of the air conditioner and accumulating the operating time of the compressor;

[0010] According to the air outlet mode of the air conditioner and the operating time of the compressor, the auxiliary air guide plate is selectively controlled to block the air flow in the air outlet duct from entering the panel duct.

[0011] The method for preventing condensation on the panel provided by an embodiment of the present invention controls the auxiliary air guide plate to block the air flow in the air outlet duct from entering the panel air duct according to the length of air outlet in different air outlet modes during operation in the cooling mode or the dehumidification mode, thereby preventing excessive condensation on the inner wall of the panel due to long-term air intake into the panel air duct.

[0012] In an optional embodiment, the air outlet mode of the air conditioner includes smart air outlet, and the method for preventing panel condensation further includes:

[0013] When the air conditioner is switched to the smart air outlet in any air outlet mode other than the smart air outlet, the operating time of the compressor is accumulated again.

[0014] In an optional embodiment, the step of selectively controlling the auxiliary air guide plate to block the airflow in the air outlet duct from entering the panel duct according to the air outlet mode of the air conditioner and the operating time of the compressor includes:

[0015] If, when the operating time of the compressor reaches a first preset time, the air outlet mode of the air conditioner is any one except the smart air outlet, the auxiliary air guide plate is controlled to block the airflow in the outlet duct from entering the panel duct.

[0016] In an optional embodiment, the step of selectively controlling the auxiliary air guide plate to block the airflow in the air outlet duct from entering the panel duct according to the air outlet mode of the air conditioner and the operating time of the compressor further includes:

[0017] If the operating time of the compressor reaches a second preset time, and the air conditioner maintains the smart air outlet mode within the second preset time, the auxiliary air guide plate is controlled to block the airflow in the outlet duct from entering the panel duct.

[0018] The present invention further provides an air conditioner, comprising a middle frame, a panel, a main air guide plate, and an auxiliary air guide plate, wherein the middle frame is provided with an air outlet duct, the panel is provided on the middle frame and forms a panel air duct with the middle frame, the air conditioner is provided with an air outlet, the panel air duct and the air outlet are both connected to the air outlet duct, a first air outlet hole is provided through the panel, and the first air outlet hole connects the panel air duct with the outside world;

[0019] The main air guide plate and the auxiliary air guide plate can be movably arranged in the air outlet duct. The main air guide plate is used to guide the airflow in the air outlet duct to flow out of the air outlet at different angles, and the auxiliary air guide plate is used to selectively guide part of the airflow in the air outlet duct into the panel air duct, and then flow into the outside through the first air outlet hole. The main air guide plate and the auxiliary air guide plate are used together to move relative to the middle frame to different working states to adjust the air outlet mode of the air conditioner.

[0020] Compared to existing technologies, the air conditioner provided by the present invention utilizes a main air guide plate and auxiliary air guide plates to coordinate airflow, enabling multiple airflow modes, with the first air outlet on the panel and the air outlet on the middle frame working in concert. This allows for switching between multiple airflow modes. This allows for a richer range of airflow modes, meeting more personalized user needs and enhancing the user experience.

[0021] In an optional embodiment, the air outlet modes of the air conditioner include zero wind feeling air outlet, ambient air outlet, downward air outlet, upward air outlet, and smart air outlet, and the auxiliary air guide plate includes an open position and a closed position. When the air conditioner is discharging air in any one of the ambient air outlet and the smart air outlet modes, the auxiliary air guide plate is in the open position, guiding part of the airflow in the air outlet duct into the panel air duct;

[0022] When the air conditioner discharges air in any one of the downward air outlet and upward air outlet modes, the auxiliary air guide plate is in the closed position, blocking the airflow in the air outlet duct from entering the panel duct.

[0023] The auxiliary air guide plate switches between the open position and the closed position, thereby selectively guiding the airflow in the outlet duct into the panel duct, enriching the air outlet mode of the air conditioner and improving the user experience.

[0024] In an optional embodiment, when the air conditioner discharges air in any one of the annular air outlet mode and the intelligent air outlet mode, the main air guide plate interferes with the movement path of the auxiliary air guide plate when the auxiliary air guide plate switches from the open position to the closed position;

[0025] When the air conditioner discharges air in any one of the downward air outlet mode and the upward air outlet mode, the main air guide plate gives way to the movement path of the auxiliary air guide plate when switching from the open position to the closed position.

[0026] In addition to the zero-windflow feature, when the auxiliary air deflector moves to the open position, it gives way to the primary air deflector in the corresponding mode. When the primary air deflector moves out of the auxiliary air deflector's path in the corresponding airflow mode, the auxiliary air deflector can be switched from the open position to the closed position. The coordinated action of the auxiliary and primary air deflectors enables switching between different airflow modes, ensuring smooth switching and saving space on the middle frame between the primary and secondary air deflectors.

[0027] In an optional embodiment, the number of the main air guide plates is multiple, and the multiple main air guide plates include a first air guide plate and a second air guide plate. The first air guide plate, the second air guide plate and the auxiliary air guide plate can be rotatably arranged in the air outlet duct. The rotation axes of the first air guide plate, the second air guide plate and the auxiliary air guide plate are perpendicular to the vertical plane, and the rotation center lines of the first air guide plate, the second air guide plate and the auxiliary air guide plate are parallel to each other.

[0028] By rotating the first air guide plate, the second air guide plate and the auxiliary air guide plate in the air outlet duct, switching between different air outlet modes is achieved.

[0029] In an optional embodiment, the first air guide plate is located between the air duct opening of the panel air duct and the second air guide plate, and compared with the first air guide plate and the second air guide plate, the air duct opening of the panel air duct is the highest in the vertical direction, and the auxiliary air guide plate is arranged at the air duct opening of the panel air duct.

[0030] In an optional embodiment, the first air guide plate and the second air guide plate each include multiple working positions, and the multiple working positions include an upper limit position, an intermediate position, a lower transition position and a lower limit position. The first air guide plate or the second air guide plate rotates unidirectionally from the upper limit position, the intermediate position, the lower transition position to the lower limit position.

[0031] Both the first air guide plate and the second air guide plate include multiple working positions including an upper limit position, an intermediate position, a lower transition position and a lower limit position. The first air guide plate and the second air guide plate are combined in different working positions, combined with the switching of the auxiliary air guide plate between the open position and the closed position, to realize the switching of the air conditioner between different air outlet modes.

[0032] In an optional embodiment, in the zero-wind-feeling air outlet state, the first air guide plate and the second air guide plate are both in the middle position, and the first air guide plate and the second air guide plate jointly cover the air outlet; in the annular air outlet state, the first air guide plate and the second air guide plate are both in the upper limit position; in the lower air outlet state, the first air guide plate and the second air guide plate are both in the lower limit position; in the upper air outlet state, the first air guide plate and the second air guide plate are both in the lower transition position; in the smart air outlet state, the first air guide plate is in the upper limit position, and the second air guide plate is in the lower limit position.

[0033] In an optional embodiment, the first air guide plate is located above and in front of the second air guide plate, and both the first air guide plate and the second air guide plate are arc-shaped plates;

[0034] In the state of the annular air outlet, the airflow of the air outlet duct flows out of the air outlet between the concave arc side of the first air guide plate and the convex arc side of the second air guide plate and between the concave arc side of the second air guide plate and the lower side wall of the air outlet duct; in the state of the lower air outlet, the airflow of the air outlet duct flows out of the air outlet between the convex arc side of the first air guide plate and the concave arc side of the second air guide plate; in the state of the upper air outlet, the airflow of the air outlet duct flows out of the air outlet between the concave arc side of the first air guide plate and the upper side wall of the air outlet duct and between the convex arc side of the first air guide plate and the concave arc side of the second air guide plate; in the state of the smart air outlet, the airflow of the air outlet duct flows out of the air outlet between the concave arc side of the first air guide plate and the concave arc side of the second air guide plate.

[0051] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0052] Please refer to Figure 1 and Figure 2 , Figure 1 FIG. 1 is a cross-sectional view of the air conditioner 100 provided in this embodiment in a state of zero wind sense air outlet. Figure 2 Shown Figure 1 A magnified schematic diagram of area A in the middle.

[0053] The air conditioner 100 provided in this embodiment is actually a wall mounted air conditioner, which includes a middle frame 110, a panel 120, a main air guide plate and an auxiliary air guide plate 150. In fact, it also includes a base, a volute, a fan and other conventional components and structures in this field, which are not further described in this embodiment.

[0054] The middle frame 110 is provided with an air outlet duct 111, and the panel 120 is set on the middle frame 110, and forms a panel air duct 121 and an air outlet 112 with the middle frame 110. The panel air duct 121 and the air outlet 112 are both connected to the air outlet duct 111, and a plurality of first air outlet holes 122 are penetrated on the panel 120, and the plurality of first air outlet holes 122 connect the panel air duct 121 with the outside world.

[0055] Specifically, the panel 120 is placed on the outer surface of the middle frame 110 and is approximately above the air outlet duct 111. The panel 120 and the outer surface of the middle frame 110 together form the panel air outlet 121. The lower edge of the panel 120 extends into the air outlet duct 111 and, together with the side walls of the air outlet duct 111, forms the air outlet 112. The lower edge of the panel 120 and the upper side walls of the air outlet duct 111 form the air outlet of the panel air outlet 121.

[0056] In this embodiment, there are two main air guide plates, namely the first air guide plate 130 and the second air guide plate 140. The first air guide plate 130, the second air guide plate 140 and the auxiliary air guide plate 150 can all be movably arranged in the air outlet duct 111. In the same oblique direction, the first air guide plate 130 is located between the air duct opening of the panel air duct 121 and the second air guide plate 140, and the auxiliary air guide plate 150 is arranged at the air duct opening of the panel air duct 121.

[0057] The first and second air guide plates 130, 140 are used to collaboratively guide the airflow in the outlet duct 111 out of the air outlet 112 at different angles. The auxiliary air guide plate 150 is used to selectively guide a portion of the airflow in the outlet duct 111 into the panel duct 121. The first, second, and auxiliary air guide plates 130, 140, 150 are used to move relative to the middle frame 110 to different operating states, thereby adjusting the airflow mode of the air conditioner 100 to one of zero-wind-feel airflow, ambient airflow, downward airflow, upward airflow, and intelligent airflow.

[0058] In fact, in this embodiment, the first air guide plate 130, the second air guide plate 140 and the auxiliary air guide plate 150 can all be rotatably arranged in the air outlet duct 111, and the rotation center lines of the first air guide plate 130, the second air guide plate 140 and the auxiliary air guide plate 150 are parallel to each other, and their respective rotation center lines are perpendicular to the vertical direction, that is, the first air guide plate 130, the second air guide plate 140 and the auxiliary air guide plate 150 are all used to rotate in a vertical plane.

[0059] The first air deflector 130 and the second air deflector 140 are both curved plates. Specifically, their respective perimeters form a rectangular trajectory, and the cross-sections of the first air deflector 130 and the second air deflector 140 in a plane perpendicular to the long sides of their respective rectangular trajectory are both arc-shaped. In practice, an air outlet frame is provided within the air outlet duct 111, and the first air deflector 130 and the second air deflector 140 are both rotatably mounted on the air outlet frame, with the rotational centerlines of the first air deflector 130 and the second air deflector 140 located on the corresponding concave arc sides.

[0060] The first air guide plate 130 and the second air guide plate 140 both include multiple working positions, including an upper limit position, an intermediate position, a lower transition position and a lower limit position. From the upper limit position, the intermediate position, the lower transition position to the lower limit position, the first air guide plate 130 or the second air guide plate 140 rotates unidirectionally.

[0061] In fact, in Figure 1 From the perspective shown, the first air guide plate 130 or the second air guide plate 140 rotates counterclockwise from the upper limit position, the middle position, the lower transition position to the lower limit position. Conversely, the first air guide plate 130 or the second air guide plate 140 rotates clockwise from the lower limit position, the lower transition position, the middle position to the upper limit position.

[0062] The auxiliary air guide plate 150 is generally a flat plate-shaped structure. The auxiliary air guide plate 150 includes an open position and a closed position that can be switched to each other. When the auxiliary air guide plate 150 is rotated to the open position, the air duct opening of the panel air duct 121 is opened, allowing the panel air duct 121 to communicate with the outlet air duct 111, thereby directing part of the airflow in the panel air duct 121 into the panel air duct 121. When the auxiliary air guide plate 150 is rotated to the closed position, the air duct opening of the panel air duct 121 is covered, thereby preventing the airflow in the outlet air duct 111 from entering the panel air duct 121.

[0063] When the air conditioner 100 is in the zero-wind state, the first air guide plate 130 and the second air guide plate 140 are both in the middle position, and the first air guide plate 130 and the second air guide plate 140 jointly cover the air outlet 112. In this state, the auxiliary air guide plate 150 is not fixed in the position, that is, the auxiliary air guide plate 150 can be in either the open position or the closed position, depending on the user's personalized needs for the zero-wind effect.

[0064] exist Figure 1 In the illustrated state, the auxiliary air guide plate 150 is in the open position. In practice, multiple second air outlet holes 135 are provided through both the first air guide plate 130 and the second air guide plate 140. In this air outlet mode, a portion of the airflow within the air outlet duct 111 enters the panel air duct 121. This portion of airflow flows out through the multiple first air outlet holes 122 provided through the panel 120. The remaining airflow within the air outlet duct 111 flows out of the air outlet 112 through the multiple second air outlet holes 135 provided through the first air guide plate 130 and the second air guide plate 140.

[0065] exist Figure 1 In the state shown, the multiple first air outlet holes 122 set on the panel 120 and the multiple second air outlet holes 135 set on the first air guide plate 130 and the second air guide plate 140 all play a role in discharging air, with a larger air outlet volume and a larger air outlet angle and air outlet area, achieving a better wind dispersion effect, thereby obtaining a better zero wind feeling effect while improving the room temperature regulation efficiency.

[0066] The auxiliary air guide plate 150 can be switched from the open position to the closed position, thereby blocking the airflow in the outlet duct 111 from entering the panel duct 121. At this time, the airflow in the outlet duct 111 only flows out through the first air guide plate 130 and the multiple second air outlet holes 135 arranged on the second air guide plate 140, thereby achieving another zero-wind effect.

[0067] It should be noted that in other embodiments, the second air outlet 135 may be provided through only one of the first air guide plate 130 and the second air guide plate 140. In this case, when the first air guide plate 130 and the second air guide plate 140 jointly cover the air outlet 112, combined with the specific position of the auxiliary air guide plate 150, a variety of different zero-wind effects can be produced.

[0068] Please refer to Figure 3 and Figure 4 , Figure 3 FIG. 1 is a cross-sectional view of the air conditioner 100 provided in this embodiment in a state of annular air discharge. Figure 4 Shown Figure 3 Schematic diagram of the enlarged area B.

[0069] exist Figure 3In the annular airflow state shown, the first air guide plate 130 and the second air guide plate 140 are both in their upper limit positions, and the auxiliary air guide plate 150 is in the open position. In this airflow mode, the auxiliary air guide plate 150 is in the open position, giving way to the first air guide plate 130. The first air guide plate 130 replaces the auxiliary air guide plate 150 to block the air duct opening of the panel air duct 121.

[0070] In this air outlet mode, although the auxiliary air guide plate 150 is in the open position, the airflow in the air outlet duct 111 is blocked by the first air guide plate 130 and can hardly enter the panel air duct 121. Only a very small amount of airflow enters the panel air duct 121 through the second air outlet hole 135 on the first air guide plate 130, which can be ignored.

[0071] In the annular airflow mode, air from the outlet duct 111 flows out of the outlet 112 between the concave side of the first air guide plate 130 and the convex side of the second air guide plate 140, and between the concave side of the second air guide plate 140 and the outlet duct 111. The angle between the airflow direction and the vertical direction is minimized. Therefore, the annular airflow mode is typically used in conjunction with the air conditioner 100 operating in a more powerful heating mode to prevent hot air from rising rapidly.

[0072] Please refer to Figure 5 and Figure 6 , Figure 5 FIG. 1 is a cross-sectional view of the air conditioner 100 provided in this embodiment in a downward air outlet state. Figure 6 Shown Figure 5 Schematic diagram of the enlarged area C in the middle.

[0073] exist Figure 5 In the illustrated downward airflow mode, both the first and second air guide plates 130, 140 are in their lower limit positions, and the auxiliary air guide plate 150 is in the closed position. In this airflow mode, the auxiliary air guide plate 150 blocks the air duct opening of the panel air duct 121, preventing airflow from the outlet duct 111 from exiting the panel 120. This ensures that airflow exits at a smaller angle to the vertical, preventing hot air from rising rapidly. Therefore, downward airflow is typically the airflow mode used by the air conditioner 100 in normal heating mode.

[0074] In the downward airflow state, the airflow from the outlet duct 111 flows out of the air outlet 112 between the convex curved side of the first air guide plate 130 and the concave curved side of the second air guide plate 140. In this state, the angle between the airflow outflow direction and the vertical direction is greater than the angle between the airflow and the vertical direction when the airflow is in the annular area. It is understandable that due to the gap between the convex curved side of the second air guide plate 140 and the lower sidewall of the outlet duct 111, a small amount of airflow inevitably flows out of the gap enclosed by the convex curved side of the second air guide plate 140 and the lower sidewall of the outlet duct 111. This airflow is negligible.

[0075] Moreover, in the downward air outlet state, the first air guide plate 130 gives way to the movement path of the auxiliary air guide plate 150 switching from the open position to the closed position, and the auxiliary air guide plate 150 can smoothly switch from the open position to the closed position.

[0076] Please refer to Figure 7 and Figure 8 , Figure 7 FIG. 1 is a cross-sectional view of the air conditioner 100 provided in this embodiment in the upward air outlet state. Figure 8 Shown Figure 7 Schematic enlargement of region D in the middle.

[0077] exist Figure 7 In the upper airflow state shown, the first air guide plate 130 and the second air guide plate 140 are both in the lower transition position, and the auxiliary air guide plate 150 is in the closed position. In this state, air from the outlet duct 111 flows out of the air outlet 112 between the concave arc side of the first air guide plate 130 and the upper side wall of the outlet duct 111, and between the convex arc side of the first air guide plate 130 and the concave arc side of the second air guide plate 140.

[0078] In practice, because the auxiliary air guide plate 150 covers the air duct opening of the panel air duct 121, the auxiliary air guide plate 150, the concave arc side of the first air guide plate 130, and the upper sidewall of the outlet air duct 111 together form a channel for airflow to flow out of the air outlet 112. Compared to other airflow modes, the angle between the airflow direction and the vertical direction in the upper airflow mode is the largest, ensuring that the airflow is blown farther and preventing the airflow from sinking rapidly. Therefore, the upper airflow mode is generally the airflow mode selected when the air conditioner 100 is operating in cooling mode.

[0079] Moreover, in the upward air outlet state, the first air guide plate 130 gives way to the movement path of the auxiliary air guide plate 150 switching from the open position to the closed position, and the auxiliary air guide plate 150 can smoothly switch from the open position to the closed position.

[0080] Please refer to Figure 9 and Figure 10 , Figure 9FIG. 1 is a cross-sectional view of the air conditioner 100 provided in this embodiment in the state of intelligent air flow. Figure 10 Shown Figure 9 Enlarged schematic diagram of area E in the middle.

[0081] exist Figure 9 In the illustrated Smart Air mode, the first air guide plate 130 is at its upper limit, and the second air guide plate 140 is at its lower limit. Air from the air duct 111 flows out of the air outlet 112 between the concave sides of the first and second air guide plates 130, 140. Because the concave sides of the first and second air guide plates 130, 140 centrally direct the airflow, Smart Air mode achieves optimal airflow concentration. Therefore, Smart Air mode is typically used by the air conditioner 100 for rapid temperature adjustment or ventilation in a specific area.

[0082] In the Smart Airflow mode, the auxiliary air duct is in the open position. Since the first air guide plate 130 is at its upper limit, this also interferes with the movement of the auxiliary air guide plate 150 from the open position to the closed position. Therefore, similar to the Ring Mode, in this airflow mode, although the auxiliary air guide plate 150 is in the open position, the airflow in the outlet duct 111 is blocked by the first air guide plate 130 and is almost unable to enter the panel duct 121. Only a very small amount of air flows into the panel duct 121 through the second air outlet hole 135 on the first air guide plate 130, which can be ignored.

[0083] In summary, the air conditioner 100 provided in this embodiment adjusts the air outlet effect and angle of the air outlet 112 and the panel 120 through the coordinated action of the first air guide plate 130, the second air guide plate 140, and the auxiliary air guide plate 150, thereby achieving the purpose of switching the air outlet mode among zero wind feeling air outlet, ambient air outlet, downward air outlet, upward air outlet, and intelligent air outlet. It can be seen that the air conditioner 100 provided in this embodiment has a richer range of air outlet modes, which can meet more personalized needs of users and enhance the user experience.

[0084] See also Figure 11 This embodiment also provides a method for preventing condensation on the panel. Figure 11 The figure shows a flowchart of the method for preventing panel condensation. This method, applied to the aforementioned air conditioner 100, aims to control the auxiliary air guide plate 150 to selectively block the air duct opening of the panel air duct 121 to prevent excessive condensation on the inner surface of the panel 120 due to prolonged air flow into the duct. This condensation then accumulates and drips from the air outlet 112 or is blown into the room with the airflow, affecting the user experience. Specifically, the method includes the following steps:

[0085] Step S101 , obtaining the operating mode of the air conditioner 100 .

[0086] It is understandable that the operating modes of the air conditioner 100 include a heating mode, a cooling mode, a ventilation mode, a dehumidification mode, and the like.

[0087] Step S102: If the operation mode is the cooling mode or the dehumidification mode, the air outlet mode of the air conditioner 100 is obtained and the operation time of the compressor is accumulated.

[0088] In this embodiment, the air outlet modes of the air conditioner 100 include zero wind feeling air outlet, ambient air outlet, downward air outlet, upward air outlet and smart air outlet.

[0089] Step S103 : When the air conditioner 100 switches to the smart air outlet mode from any air outlet mode except the smart air outlet mode, the operating time of the compressor is accumulated again.

[0090] It is understood that when the air conditioner 100 is determined to be in cooling mode or dehumidification mode, the timer starts counting the compressor's operating time. During this process, if the air outlet mode of the air conditioner 100 is switched from any of the following: zero wind sense air outlet, ambient air outlet, downflow air outlet, or upflow air outlet to smart air outlet, the timer is reset and the compressor's operating time starts again from zero.

[0091] In step S104 , according to the air outlet mode of the air conditioner 100 and the operating time of the compressor, the auxiliary air guide plate 150 is selectively controlled to block the air flow in the air outlet duct 111 from entering the panel duct 121 .

[0092] In this embodiment, whether the inner surface of the panel 120 reaches the condensation condition is determined by the air outlet mode of the air conditioner 100 and the operating time of the compressor. When it is determined that the condensation condition is reached, the auxiliary air guide plate 150 is controlled to block the air flow in the outlet duct 111 from entering the panel duct 121, thereby avoiding condensation on the panel 120.

[0093] For details, please refer to Figure 12 , step S104 further includes the following sub-steps:

[0094] In sub-step S1041, if the air outlet mode of the air conditioner 100 is any one except the smart air outlet when the operating time of the compressor reaches the first preset time, the auxiliary air guide plate 150 is controlled to block the air flow in the air outlet duct 111 from entering the panel duct 121.

[0095] In sub-step S1042, if the operating time of the compressor reaches a second preset time, and the air conditioner 100 maintains the smart air outlet mode within the second preset time, the auxiliary air guide plate 150 is controlled to block the air flow in the outlet duct 111 from entering the panel duct 121.

[0096] In this embodiment, the first preset duration is preferably 15 minutes, and the second preset duration is preferably 16 minutes. Furthermore, to prevent the auxiliary air deflector 150 from obstructing the rotation of the first air deflector 130, the method for preventing condensation on the panel 120 provided in this embodiment further includes: when the auxiliary air deflector 150 is in the closed position, when the first air deflector 130 rotates from the lower limit position to the upper limit position by a preset angle, controlling the auxiliary air deflector 150 to move from the closed position to the open position. In this embodiment, the preferred value of the preset angle is 43°.

[0097] It can be seen that the method for preventing panel condensation provided in this embodiment can prevent the low-temperature airflow from blowing towards the inner surface of the panel 120 for a long time during operation in the cooling mode or dehumidification mode, thereby avoiding excessive condensation, and further preventing the condensation from gathering into condensed water droplets, thereby improving the user experience.

[0098] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the scope defined by the claims.
