[0041] The principles and features of the present application are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present application and are not used to limit the scope of the present application.

[0042] Research has found that in the related art, when the air guide plate assembly of an air conditioner with multiple air outlets closes some of the air outlets, the air guide plate assembly in the closed state is prone to condensation and dripping. The reason is that there is a gap between the circumferential end of the air guide plate assembly in the closed state and the wall of the closed air outlet. Therefore, the air guide plate assembly cannot completely close the corresponding air outlet when it is closed. In this way, during the use of the air conditioner, when some of the air guide plate assemblies are in the closed state, some airflow will pass through the gap, and it is impossible to effectively isolate the hot and cold air on both sides of the closed air guide plate assembly. When the air outlet temperature of the air conditioner is low and the indoor temperature is high and humid, the meeting of cold and hot air can easily cause condensation on the air guide plate assembly, causing dripping.

[0043] For this reason, Figures 1 to 19 As shown, an embodiment of the present application provides an air conditioner, comprising: a shell 1 and an air guide mechanism 2.

[0044] like Figure 3 As shown, the housing 1 is provided with an air duct 14 and a plurality of air outlets (such as the first air outlet 151 and the second air outlet 152 described below). Each air outlet is configured to be connected to the air duct 14 to form an air outlet passage. The air outlet may be an air outlet of the air conditioner, or an opening inside the air conditioner located upstream of the air outlet. Fig.11 As shown, an indoor heat exchanger 3 and a fan 4 may be provided in the air duct 14. The fan 4 rotates to allow indoor air to enter the air duct 14, and after heat exchange with the indoor heat exchanger 3, the indoor air is discharged to the indoor space through the air outlet channel, thereby regulating the temperature of the indoor air.

[0045] The air guide mechanism 2 includes an air guide plate assembly movably connected to the housing 1. The air guide plate assembly is configured to control the opening and closing of multiple air outlets so that the air conditioner has multiple air outlet modes. In addition, the air guide plate assembly is configured to overlap and seal with the housing 1 when at least some of the air outlets are closed to seal the closed air outlets. The air guide mechanism 2 may also include a driving mechanism (not shown in the figure) connected to the air guide plate assembly, and the driving mechanism is configured to drive the air guide plate assembly to move relative to the housing 1.

[0046] The air conditioner provided in the embodiment of the present application has multiple air outlets and an air guide plate assembly matched with the multiple air outlets, so that the air conditioner can have multiple air outlet modes, which is conducive to meeting the different air outlet requirements of users, thereby improving the user experience. In addition, the air guide plate assembly is mainly used as a damper. When closing at least part of the air outlet, the air guide plate assembly can overlap and seal with the shell 1, so that the corresponding air outlet can be completely closed, thereby realizing the sealing of the air guide plate assembly to the air outlet, which can effectively isolate the hot and cold air on both sides of the air guide plate assembly in the closed state, thereby preventing the air guide plate assembly in the closed state from condensing and causing dripping, and can also prevent air leakage and whistling at the air outlet in the closed state, thereby improving the user experience.

[0047] Among them, in the embodiment of the present application, the air conditioner can be an indoor unit of a split-type air conditioner, such as a duct-type indoor unit, a wall-mounted indoor unit, etc., or it can be a split-type air conditioner including an indoor unit and an outdoor unit, or it can be an integrated air conditioner.

[0048] In some exemplary embodiments, the air guide mechanism 2 includes an air guide plate (such as the first air guide plate 21 and the second air guide plate 22 described below), such as Figure 1 and Figure 2 As shown, a rotating portion 231 (such as the first rotating portion 211 and the second rotating portion 221 described below) is provided at one end of the air guide plate in the width direction, and a sealing edge 25 is provided at the circumferential end of the air guide plate, such as Figure 2 As shown, the sealing edge 25 is configured to overlap and seal with the overlapping edge on the circumferential outer side of the air outlet so that the air guide plate is closed and the air outlet is sealed.

[0049] In some embodiments, Figure 1 and Figure 2 As shown, the air deflector includes: an air deflector body 23 and a heat-insulating layer 24. The heat-insulating layer 24 is arranged on one side of the air deflector body 23 in the thickness direction and connected to the air deflector body 23. The air deflector body 23 and / or the heat-insulating layer 24 are provided with a sealing edge 25.

[0050] This is more conducive to isolating the heat transfer on both sides of the air guide plate, thereby preventing condensation from occurring in the air guide plate assembly.

[0051] In some exemplary embodiments, a plurality of overlapping edges (such as the first overlapping edge to the eighth overlapping edge described below) are provided in the shell 1, and an overlapping edge is provided on the circumferential outer side of each air outlet, and the overlapping edge is configured to overlap and seal with the air guide plate assembly so that the air guide plate assembly seals the closed air outlet.

[0052] The conventional air deflector assembly is located in the air outlet, and a gap needs to be reserved between the air deflector assembly and the air outlet wall to avoid interference during the rotation of the air deflector assembly. Therefore, the air deflector assembly cannot completely close the air outlet when it is closed.

[0053] In the air conditioner provided in the embodiment of the present application, the circumferential end of the air guide plate is not inside the air outlet, but is located outside the air outlet in the circumferential direction (for example, the position of the air guide plate can be moved from inside the air outlet to the upstream side or downstream side of the air outlet). Therefore, when the air guide plate assembly closes the air outlet, the circumferential end of the air guide plate assembly is located outside the corresponding air outlet, and can achieve overlapping sealing with the overlapping edge around the corresponding air outlet to ensure that the air outlet is completely closed and sealed.

[0054] Among them, the sealing edge 25 can be a prismatic structure (for achieving line contact) or a planar structure (for achieving surface contact); the overlapping edge can be a prismatic structure (for achieving line contact) or a planar structure (for achieving surface contact), as long as overlapping sealing can be achieved.

[0055] Furthermore, the sealing edge 25 and the overlapping edge can be in hard contact, that is, the sealing edge 25 and the overlapping edge are both hard structures (such as plastic structures, metal structures, etc.), and a seal is formed by overlapping the hard structures. Alternatively, the sealing edge 25 and the overlapping edge can also be in soft contact, that is, at least one of the sealing edge 25 and the overlapping edge is a soft structure (such as soft sealing strips such as silicone and rubber, thermal insulation cotton, etc.), and a seal is formed by overlapping the soft structures or overlapping the soft structures with the hard structures.

[0056] In some exemplary embodiments, the air deflector body 23 is an injection molded part, so that the shape of the air deflector body 23 can be reasonably set according to needs. The heat insulation layer 24 can be a foam part.

[0057] In some exemplary embodiments, the heat-insulating layer 24 and the air guide plate body 23 are configured as an integrated structure. The integrated structure has high connection strength, which is beneficial to improving the service life of the air guide plate.

[0058] For example, the air guide plate body 23 is firstly injection molded and then placed into a mold of the thermal insulation layer 24 . The material of the thermal insulation layer 24 in liquid state is injected into the mold. After solidification, the thermal insulation layer 24 forms an integrated structure with the air guide plate body 23 .

[0059] Of course, the air guide plate body 23 and the heat insulation layer 24 may also be a split assembly structure.

[0060] In some exemplary embodiments, Figure 1 and Figure 2 As shown, the rotating part 231 is provided on the air guide plate body 23, and the rotating part 231 is provided with a filling groove 232. The filling groove 232 is provided with an opening, and the opening faces the other end of the air guide plate body 23, and one end of the thermal insulation layer 24 is embedded in the filling groove 232. This is conducive to increasing the connection area between the thermal insulation layer 24 and the air guide plate body 23, thereby further improving the connection strength between the thermal insulation layer 24 and the air guide plate body 23.

[0061] In some exemplary embodiments, the cross-sectional contour of the filling slot 232 is set to be an arc shape, and the width of the opening is less than or equal to the diameter of the filling slot 232. In this way, one end of the thermal insulation layer 24 in the width direction will be limited in the filling slot 232 and will not easily escape from the opening of the filling slot 232, thereby further improving the connection strength between the thermal insulation layer 24 and the air guide plate body 23.

[0062] The cross-sectional contour line of the filling slot 232 refers to the contour line of the cross section perpendicular to the length direction of the air guide plate.

[0063] In some exemplary embodiments, the heat-insulating layer 24 is located at both ends of the width direction of the portion outside the filling groove 232, and is configured to smoothly connect with both ends of the width direction of the air guide body 23. In this way, both ends of the width direction of the air guide as a whole are smooth surfaces, which is conducive to reducing wind resistance.

[0064] In some embodiments, an end of the air guide plate away from the rotating portion 231 is provided with an air guide slope, which facilitates guiding the airflow to flow along the air guide plate to reduce wind resistance.

[0065] In some exemplary embodiments, Figure 1 As shown, a first connection portion 2311 and a second connection portion 2312 are respectively provided at two ends of the rotating portion 231 , the first connection portion 2311 is configured to be connected to the driving member, and the second connection portion 2312 is configured to be rotatably connected to the supporting carrier.

[0066] The driving member may be, but is not limited to, a stepping motor. The supporting carrier may be, but is not limited to, a housing 1 of an air conditioner.

[0067] In some exemplary embodiments, Figure 1 As shown, the rotating portion 231 is further provided with at least one third connecting portion 2313 , and the third connecting portion 2313 is located between the first connecting portion 2311 and the second connecting portion 2312 , and the third connecting portion 2313 is configured to be rotatably connected to the supporting carrier.

[0068] This can provide better support for the air guide plate, which is beneficial for preventing the air guide plate from deforming during use and affecting the normal use of the air guide plate.

[0069] like Figure 1 As shown, the number of the third connection parts 2313 can be multiple, and the multiple third connection parts 2313 are arranged at intervals along the length direction of the air guide plate.

[0070] In some exemplary embodiments, Figure 1 and Figure 2 As shown, the rotating part 231 is configured as a columnar structure extending along the length direction of the air guide plate, and the first connecting part 2311 includes a rotating shaft or an axis hole. The second connecting part 2312 includes an axis hole or a rotating shaft. The third connecting part 2313 includes a supporting shaft (such as Figure 1 and Figure 2 shown).

[0071] When the first connection part 2311 includes a rotating shaft, the output shaft of the driving member can be provided with a shaft hole; when the first connection part 2311 includes a shaft hole, the output shaft of the driving member can be provided with a rotating shaft. Thus, the driving member and the first connection part 2311 can achieve shaft-hole matching, such as matching between a non-circular shaft and a non-circular hole or interference matching between a circular shaft and a circular hole, to ensure that the driving member can drive the air guide plate to rotate.

[0072] When the second connection part 2312 includes a rotating shaft, the support carrier can be provided with an axis hole; when the second connection part 2312 includes an axis hole, the support carrier can be provided with a rotating shaft. Thus, the support carrier and the second connection part 2312 can achieve the axis hole matching, such as the clearance matching of the circular shaft and the circular hole, to ensure that the air guide plate can rotate relative to the support carrier.

[0073] When the third connection part 2313 includes a support shaft, the support carrier is correspondingly provided with a support hole, and the support hole can be provided with a notch opening toward the air guide plate, so that the support shaft can be embedded in the support hole through the notch and can rotate relative to the support hole.

[0074] In some exemplary embodiments, Figure 1As shown, the rotating part 231 is provided with an avoidance notch 2314, and the support shaft is located in the avoidance notch 2314. In this way, the diameter of the support shaft is smaller than the diameter of the rotating part 231 and is arranged concentrically with the rotating part 231. While playing a supporting role, the contact area between the support shaft and the support carrier can be reduced to reduce friction resistance.

[0075] In some exemplary embodiments, Figure 3 As shown, the plurality of air outlets include a first air outlet 151 and a second air outlet 152, and the air outlet directions of the first air outlet 151 and the second air outlet 152 are different. The first air outlet 151 is configured to be connected to the air duct 14 to form a first air outlet channel, and the second air outlet 152 is configured to be connected to the air duct 14 to form a second air outlet channel. In other words, when the first air outlet 151 is connected to the air duct 14, the air outlet channel formed by the connection between the two is the first air outlet channel. In other words, when the second air outlet 152 is connected to the air duct 14, the air outlet channel formed by the connection between the two is the second air outlet channel.

[0076] like Figure 3 As shown, the air guide plate assembly includes a first air guide plate 21 and a second air guide plate 22 located in the housing 1 and movably connected to the housing 1. The first air guide plate 21 cooperates with the second air guide plate 22 to control the opening and closing of the first air outlet 151 and the second air outlet 152, so that the air conditioner has a first air outlet mode (such as Figure 7 , Fig.15 and Fig.16 ), a second air outlet mode in which the first air outlet channel is disconnected and the second air outlet channel is connected (as shown in Figure 3 , Fig.17 and Fig.18 ), and a third air outlet mode in which both the first air outlet channel and the second air outlet channel are connected (as shown Fig.10 shown).

[0077] In this way, the air conditioner has three air outlet modes, which is convenient for users to reasonably select the air outlet mode according to their needs. In addition, compared with the solution with more air outlets and more air guide plates, the structure of this solution is relatively simple, which is conducive to reducing production costs.

[0078] For example, the first air outlet 151 can be a downwind air outlet, discharging air downward; the second air outlet 152 can be a side air outlet, discharging air horizontally, then the first air outlet mode is the downwind air outlet mode, the second air outlet mode is the downwind air outlet mode, and the third air outlet mode is the double air outlet mode. When the user needs fast cooling or fast heating, the first air outlet mode can be selected, and the airflow is discharged downward through the first air outlet channel, such as Figure 7 , Fig.15 and Fig.16As shown, it is convenient for the temperature of the lower area to quickly decrease or increase. When the user wants to avoid direct blowing, the second air outlet mode can be selected, and the air flow is discharged laterally through the second air outlet channel, such as Figure 3 , Fig.17 and Fig.18 As shown, it is convenient to blow air from a long distance to avoid blowing directly on the user. When the user wants to cool or heat the entire area evenly, the third air outlet mode can be selected, and the airflow will be blown out through the first air outlet channel and the second air outlet channel together, as shown in FIG. Fig.10 As shown, it is possible to quickly adjust the temperature of the area below and nearby, and also to supply air over long distances, so that the temperature of distant areas can also be quickly adjusted.

[0079] Of course, the number of air outlets is not limited to two, the number of air guide plates is not limited to two, and the number of air outlet modes is not limited to three, and the number can be adjusted as needed.

[0080] In some exemplary embodiments, Figure 3 As shown, the second air outlet 152 includes a first sub-air outlet 1521 and a second sub-air outlet 1522 that are interconnected, and the second sub-air outlet 1522 is located between the first air outlet 151 and the first sub-air outlet 1521 .

[0081] like Fig.13 and Fig.14 As shown, the first air guide plate 21 is rotatably connected to the shell 1, and is configured to be able to rotate relative to the shell 1 between a first position closing the first air outlet 151 and opening the second sub-air outlet 1522, a second position opening the first air outlet 151 and the second sub-air outlet 1522, and a third position opening the first air outlet 151 and closing the second sub-air outlet 1522.

[0082] like Fig.13 and Fig.14 As shown, the second air guide plate 22 is rotatably connected to the housing 1 and is configured to be rotatable relative to the housing 1 between a fourth position closing the first sub-air port 1521 and a fifth position opening the first sub-air port 1521 .

[0083] When the first air guide plate 21 is in the third position and the second air guide plate 22 is in the fourth position, the first air outlet 151 is opened and the second air outlet 152 is closed, and the air conditioner is in the first air outlet mode. Figure 7 shown.

[0084] When the first air guide plate 21 is in the first position and the second air guide plate 22 is in the fifth position, the first air outlet 151 is closed and the second air outlet 152 is opened, and the air conditioner is in the second air outlet mode. Figure 3 shown.

[0085] When the first air guide plate 21 is in the second position and the second air guide plate 22 is in the fifth position, the first air outlet 151 is opened, the second air outlet 152 is opened, and the air conditioner is in the third air outlet mode. Fig.10 shown.

[0086] In other words, the first air guide plate 21 is used to control the opening and closing of the first air outlet 151 and the opening and closing of the second sub-air outlet 1522 (a part of the second air outlet 152). The second air guide plate 22 is used to control the opening and closing of the first sub-air outlet 1521 (another part of the second air outlet 152), so the first air guide plate 21 and the second air guide plate 22 jointly control the opening and closing of the second air outlet 152. In this way, the widths of the first air outlet 151 and the second air outlet 152 can be set to different sizes, and the widths of the first air guide plate 21 and the second air guide plate 22 will not be too large, which is conducive to optimizing the structural layout of the air conditioner and reducing the size of the air conditioner.

[0087] Of course, the first air guide plate 21 and the second air guide plate 22 may also control the opening and closing of the first air outlet 151 and the second air outlet 152 respectively. Alternatively, the second air guide plate 22 may be eliminated, and the first air guide plate 21 may control the opening and closing of the first air outlet 151 and the second air outlet 152. Alternatively, the first air outlet 151 may also be controlled by two air guide plates to open and close.

[0088] In some exemplary embodiments, Figures 3 to 6 As shown, based on the first air guide plate 21 being located at the first position, the circumferential end of the first air guide plate 21 is located at the circumferential outer side of the first air outlet 151 and overlaps and seals with the shell 1 to seal the first air outlet 151 .

[0089] like Figures 7 to 9 As shown, based on the first air guide plate 21 being located at the third position, the circumferential end of the first air guide plate 21 is located at the circumferential outer side of the second sub-air outlet 1522 and overlaps and seals with the shell 1 and the second air guide plate 22 to seal the second sub-air outlet 1522.

[0090] like Figures 7 to 9 As shown, based on the second air guide plate 22 being located at the fourth position, the circumferential end of the second air guide plate 22 is located at the circumferential outer side of the first sub-air outlet 1521 and overlaps and seals with the shell 1 and the first air guide plate 21 to seal the first sub-air outlet 1521.

[0091] In this way, in the first air outlet mode, the first air guide plate 21 and the second air guide plate 22 can completely seal the second air outlet 152, effectively isolating the cold and hot air on both sides of the first air guide plate 21 and the second air guide plate 22 in the closed state, thereby avoiding the formation of condensation on the first air guide plate 21 and the second air guide plate 22.

[0092] In the second air outlet mode, the first air guide plate 21 can completely seal the first air outlet 151, effectively isolating the cold and hot air on both sides of the first air guide plate 21, thereby avoiding the formation of condensation on the first air guide plate 21 in the closed state.

[0093] In some exemplary embodiments, Figure 4 As shown, a first rotating portion 211 rotatably connected to the housing 1 is provided at one end of the first air guide plate 21 in the width direction, and the first rotating portion 211 is located between the first air outlet 151 and the second sub-air outlet 1522. A second rotating portion 221 rotatably connected to the housing 1 is provided at an end or between the two ends in the width direction of the second air guide plate 22.

[0094] In other words, if Figure 4 As shown, the rotating portion 231 of the first air guide plate 21 is arranged at one end in the width direction of the first air guide plate 21, so that the first air guide plate 21 can rotate between the first air outlet 151 and the second sub-air outlet 1522. When the first air outlet 151 is rotated to close, the second sub-air outlet 1522 is opened, and the first air guide plate 21 is located in the first position; when the second sub-air outlet 1522 is rotated to close, the first air outlet 151 is opened, and the air guide plate is located in the third position; when the air guide plate is rotated to between the first air outlet 151 and the second sub-air outlet 1522, both the first air outlet 151 and the second sub-air outlet 1522 are opened, and the air guide plate is located in the second position. The opening angle of the first air guide plate 21 when it is located in the second position can be reasonably determined according to the positions of the first air outlet 151 and the second sub-air outlet 1522, so that the airflow can flow smoothly along the two plate surfaces of the first air guide plate 21 to the first air outlet 151 and the second sub-air outlet 1522, respectively, to reduce the wind resistance generated by the first air guide plate 21.

[0095] The position of the rotating portion 231 of the second air guide plate 22 is not limited, and can be set at one end of the second air guide plate 22 in the width direction (such as Figure 7 As shown), it can also be set between the two ends of the second air guide plate 22 in the width direction.

[0096] In some exemplary embodiments, the driving mechanism includes a first driving member and a second driving member, wherein the first driving member is connected to one end of the first rotating portion 211 and is configured to drive the first air guide plate 21 to rotate. The second driving member is connected to one end of the second rotating portion 221 and is configured to drive the second air guide plate 22 to rotate. The other end of the first rotating portion 211 is rotatably connected to the housing 1. The other end of the second rotating portion 221 is rotatably connected to the housing 1.

[0097] The connection mode between the first rotating part 211 and the first driving member can be a shaft-hole matching mode, such as the matching between a non-circular shaft and a non-circular hole or the interference fit between a circular shaft and a circular hole. The connection mode between the first rotating part 211 and the housing 1 can be a shaft-hole matching mode, such as the clearance fit between a circular shaft and a circular hole. The connection mode between the second rotating part 221 and the second driving member can be a shaft-hole matching mode, such as the matching between a non-circular shaft and a non-circular hole or the interference fit between a circular shaft and a circular hole. The connection mode between the second rotating part 221 and the housing 1 can be a shaft-hole matching mode, such as the clearance fit between a circular shaft and a circular hole.

[0098] The first driving member may be, but is not limited to, a stepping motor. The second driving member may be, but is not limited to, a stepping motor. The first driving member and the second driving member may be installed in the housing 1.

[0099] In some exemplary embodiments, Figure 3 and Figure 7 As shown, the housing 1 includes a shell 11, a water receiving tray 12 connected to the shell 11, and an air guide support 13 connected to the shell 11 and the water receiving tray 12. The air guide support 13 is provided with a second air outlet 152, and the water receiving tray 12 and the air guide support 13 enclose a first air outlet 151. The first air guide plate 21 and the second air guide plate 22 are both rotatably connected to the air guide support 13.

[0100] Among them, Fig.11 As shown, the water receiving pan 12 can be located in the outer shell 11 and located at the lower side of the indoor heat exchanger 3, and the water receiving pan 12 can be connected to the bottom of the outer shell 11. The air guide support 13 can be located in the outer shell 11 and connected to the front of the outer shell 11 and the top of the water receiving pan 12. The water receiving pan 12 can be provided with an air passage opening. One end (lower end) of the air guide support 13 close to the water receiving pan 12 can be connected to the water receiving pan 12 and connected to the end of the air passage opening, so that the water receiving pan 12 and the air guide support 13 enclose a first air outlet 151. The lower end of the outer shell 11 can be open, and the shell 1 can also include a cover plate, which is covered on the open end of the outer shell 11 and is provided with a avoidance opening corresponding to the first air outlet 151.

[0101] like Figure 4 As shown, the water receiving tray 12 may be provided with a support step 124, and the support step 124 is located on the upper side of the air opening. The bottom of the air guide support 13 may be provided with a support portion 131, and the support portion 131 is supported on the support step 124 and encloses the first air outlet 151 with the water receiving tray 12. The first rotating portion 211 of the first air guide plate 21 may be rotatably connected to the support portion 131 of the air guide support 13.

[0102] Of course, the first air outlet 151 and the second air outlet 152 may also be disposed on the housing 11 .

[0103] In some exemplary embodiments, Figure 4 and Figure 7 As shown, the air guide support 13 is provided with a first arc groove 132 and a second arc groove 133 , the first arc groove 132 is configured to install the first rotating part 211 and limit the rotation range of the first rotating part 211 , and the second arc groove 133 is configured to install the second rotating part 221 and limit the rotation range of the second rotating part 221 .

[0104] The shapes of the first rotating part 211 and the second rotating part 221 are respectively adapted to the first arc groove 132 and the second arc groove 133. This facilitates limiting the rotation angle of the first air guide plate 21 and the second air guide plate 22 by mechanical limiting, and also facilitates overlapping sealing.

[0105] In some exemplary embodiments, Figure 4 , Figure 5 and Figure 6 As shown, the water receiving tray 12 is provided with a first overlapping edge 121, a second overlapping edge 122 and a third overlapping edge 123 which are sequentially arranged along the circumference of the first air outlet 151. Figure 7 , Figure 8 and Fig. 9 As shown, the air guide support 13 is provided with a fourth lap edge 134 arranged opposite to the second lap edge 122 and connected to the first lap edge 121 and the third lap edge 123, and a fifth lap edge 135, a sixth lap edge 136, a seventh lap edge 137 and an eighth lap edge 138 arranged in sequence along the circumference of the second air outlet 152.

[0106] like Figures 4 to 6 As shown, based on the first air guide plate 21 being located at the first position, the circumferential end of the first air guide plate 21 overlaps and seals with the first overlapping edge 121 , the second overlapping edge 122 , the third overlapping edge 123 and the fourth overlapping edge 134 .

[0107] like Figures 7 to 9 As shown, based on the first air guide plate 21 being located at the third position, the circumferential end of the first air guide plate 21 is overlapped and sealed with the fifth overlap edge 135, the sixth overlap edge 136, one end of the second air guide plate 22 close to the first air guide plate 21 and the eighth overlap edge 138.

[0108] like Figures 7 to 9 As shown, based on the second air guide plate 22 being located at the fourth position, the circumferential end of the second air guide plate 22 is overlapped and sealed with the seventh overlap edge 137, the sixth overlap edge 136, one end of the first air guide plate 21 close to the second air guide plate 22 and the eighth overlap edge 138.

[0109] The first air guide plate 21 may have two short sides parallel to each other and two long sides parallel to each other. The long side and the short side may be perpendicular to each other, and the short side may be a straight side or an arc side. The first overlapping side 121 and the third overlapping side 123 may be short sides, which are used to overlap and seal with the two short sides of the first air guide plate 21. The second overlapping side 122 and the fourth overlapping side 134 may be long sides, which are used to overlap and seal with the two long sides of the first air guide plate 21.

[0110] The second air guide plate 22 may have two short sides parallel to each other and two long sides parallel to each other. The long sides and the short sides may be perpendicular to each other, and the short sides may be straight sides or arcuate sides. The sixth overlapping side 136 and the eighth overlapping side 138 may be short sides, which are used to overlap and seal with the two short sides of the first air guide plate 21 and the two short sides of the second air guide plate 22. The fifth overlapping side 135 and the seventh overlapping side 137 may be long sides, which are used to overlap and seal with the two long sides of the second air guide plate 22.

[0111] Among them, the first overlapping edge 121, the second overlapping edge 122, the third overlapping edge 123, the fourth overlapping edge 134, the fifth overlapping edge 135, the sixth overlapping edge 136, the seventh overlapping edge 137 and the eighth overlapping edge 138 can be a prismatic structure (in line contact with the first air guide plate 21 / the second air guide plate 22) or a planar structure (in surface contact with the first air guide plate 21 / the second air guide plate 22), as long as overlapping sealing can be achieved.

[0112] In some exemplary embodiments, Figure 3 and Figure 7 As shown, the air guide support 13 is provided with a receiving groove 139. Based on the second air guide plate 22 being located at the fifth position, at least a portion of the second air guide plate 22 is embedded in the receiving groove 139, so that a side surface of the second air guide plate 22 constitutes a portion of the channel wall of the second air outlet channel. This is conducive to reducing the wind resistance generated by the second air guide plate 22 and is conducive to increasing the air volume in the second air outlet mode and the third air outlet mode.

[0113] In some exemplary embodiments, the first air port 151 and the second air port 152 are located in the housing 1, and the water receiving tray 12 is further provided with a first air outlet 161 (eg, Fig.12 As shown in FIG. 1 , a first air passage is formed between the first air port 151 and the first air outlet 161. The air guide support 13 is further provided with a second air outlet 162 (as shown in FIG. 1 ) which is in communication with the second air port 152. Fig.12 As shown in FIG. 1 , a second air passage is formed between the second air port 152 and the second air outlet 162. This facilitates reasonable arrangement of the positions of the first air port 151 and the second air port 152, and the shapes of the first air guide plate 21 and the second air guide plate 22 according to needs, which is beneficial to optimizing the structural layout of the air conditioner without affecting the appearance of the air conditioner.

[0114] like Fig.12 As shown, the first air outlet 161 is arranged in the horizontal direction, and the second air outlet 162 is arranged in the vertical direction. For example, the first air outlet 161 can be arranged downward, and the second air outlet 162 can be arranged forward, then the first air outlet mode is the downward air outlet mode, the second air outlet mode is the side air outlet mode, and the third air outlet mode is the double air outlet mode.

[0115] In other embodiments, the first air vent 151 and the second air vent 152 may also be air outlets, and there is no need to additionally provide the first air outlet 161 and the second air outlet 162. In the above solution, the first air outlet 161 is provided on the water receiving tray 12, and the second air outlet 162 is provided on the air guide support 13.

[0116] In some exemplary embodiments, the housing 1 is provided with an air inlet 111 communicating with the air duct 14, and the air inlet 111 is provided at the bottom and / or the side of the housing 1. In other words, the air conditioner can be provided with side air intake (such as Fig.16 and Fig.18 As shown), or downward air intake (as shown Fig.15 and Fig.17 It is convenient to make reasonable selection according to the installation scenario, which is beneficial to expand the scope of application scenarios.

[0117] In some exemplary embodiments, Fig.12 As shown, the width W1 of the first air outlet 161 is smaller than the width W2 of the second air outlet 162. This is beneficial to reducing the width of the air outlet opening of the ceiling 6 bottom plate of the air conditioner installed in the ceiling 6, which is beneficial to optimizing the user's decoration aesthetics, and also takes into account the indoor long-distance large air volume demand, which is beneficial to improving the uniformity of indoor temperature.

[0118] In some exemplary embodiments, Fig.12 As shown, an air outlet flange 163 is protrudingly provided at the second air outlet 162. A ventilation component such as a canvas hose can be sleeved on the air outlet flange 163, so that the wind output from the second air outlet 162 can be transported to the air outlet opening on the ceiling 6 through the ventilation component.

[0119] Similarly, if Fig.12 As shown, an air outlet flange 163 may also be protrudingly provided at the first air outlet 161 , so that the air output from the first air outlet 161 can be transported to the air outlet opening on the ceiling 6 through the ventilation component.

[0120] One end of the housing 1 connected to the air outlet flange 163 is set as the reference end 17. Fig.12 At least one of the rotation axis of the first air guide plate 21 and the rotation axis of the second air guide plate 22 is located on a side of the reference end 17 away from the air outlet flange 163 .

[0121] The side air outlet is generally forward air outlet, so the reference end 17 can be the front end, and at least one of the rotation axis of the first air guide plate 21 and the rotation axis of the second air guide plate 22 is located at the rear side of the air outlet flange 163, that is, located inside the housing 1. In this way, the first air guide plate 21 and the second air guide plate 22 can be basically located inside the housing 1 during the rotation process.

[0122] In some exemplary embodiments, the air conditioner is configured to be used in conjunction with the first air outlet panel 51 and the second air outlet panel 52, such as Fig.19 The first air outlet panel 51 is disposed correspondingly to the first air outlet 161 , and the second air outlet panel 52 is disposed correspondingly to the second air outlet 162 .

[0123] The first air outlet panel 51 and the second air outlet panel 52 are configured as engineering grilles for installation in the installation carrier. Alternatively, the first air outlet panel 51 and the second air outlet panel 52 are configured as electric panels connected to the housing 1 .

[0124] In other words, the air conditioner provided in the embodiment of the present application can be matched with an ordinary engineering grille, which is more coordinated with the home decoration style and is very popular among users; it can also be matched with an electric panel to further improve the user experience.

[0125] It has been verified through experiments that when the duct-type indoor unit provided in the embodiment of the present application is used in conjunction with a common engineering grille, hot air can effectively fall to the ground in the heating mode. Fig.21 As shown in the indoor temperature cloud map, the orange-red area is located near the ground (about 0.1m from the ground), indicating that the temperature in the ground area is higher.

[0126] In some exemplary embodiments, Fig.12 As shown, the rotation axis of the first air guide plate 21 and the rotation axis of the second air guide plate 22 are separated on both sides of the bisecting plane 18 perpendicular to the thickness direction of the housing 1. In this way, the space in the thickness direction of the housing 1 can be reasonably utilized, which is conducive to optimizing the structural layout of the air conditioner.

[0127] like Fig. 20 As shown, the embodiment of the present application further provides a control method, which is used for the air conditioner in any one of the above embodiments, and the control method includes:

[0128] Step S202: Determine whether the current working condition is in a set condensation working condition;

[0129] Step S204: obtaining the air outlet mode of the air conditioner;

[0130] Step S206: controlling the air guide mechanism 2 according to the air outlet mode of the air conditioner to limit condensation at the air outlet.

[0131] The condensation working condition is set to refer to the working condition where condensation is easily generated at the air outlet during the operation of the air conditioner. Condensation at the air outlet refers to condensation generated on the components in or near the air outlet. The components near the air outlet may include but are not limited to: the air guide plate assembly, the water receiving tray 12, the air guide support 13, etc.

[0132] The control method provided in the embodiment of the present application can control the air guide mechanism 2 according to the air outlet mode of the air conditioner when it is determined that condensation is likely to be generated at the air outlet during the operation of the air conditioner, so as to limit the generation of condensation at the air outlet, thereby helping to further reduce the risk of dripping caused by condensation generated by the air conditioner, and helping to further improve the user experience.

[0133] In some exemplary embodiments, determining that the current operating condition is in a set condensation operating condition includes:

[0134] Obtain indoor temperature, indoor humidity, and temperature of indoor heat exchanger 3 of the air conditioner;

[0135] Based on the indoor temperature being greater than or equal to the first set temperature, the indoor humidity being greater than or equal to the set humidity, and the temperature of the indoor heat exchanger 3 of the air conditioner being less than or equal to the second set temperature, it is determined that the current operating condition is in the set condensation operating condition.

[0136] When the indoor temperature is greater than or equal to the first set temperature and the indoor humidity is greater than or equal to the set humidity, it indicates that the indoor air is in a high temperature and high humidity state. When the temperature of the indoor heat exchanger 3 is less than or equal to the second set temperature, it indicates that the air outlet temperature is too low. Especially for multi-split air conditioners, when the temperature of the indoor heat exchanger 3 is less than or equal to the second set temperature, it indicates that the output energy of the outdoor unit is much greater than that required by the indoor unit, but the output can no longer be reduced, so the risk of condensation is very high.

[0137] When the outlet air temperature is too low and meets the indoor air with high temperature and humidity, condensation is likely to occur. Therefore, the current working condition can be determined as the set condensation working condition.

[0138] The temperature of the indoor heat exchanger 3 can be determined by obtaining the tube temperature of the output tube of the indoor heat exchanger 3. The indoor temperature can be determined by an indoor temperature sensor. The indoor humidity can be determined by an indoor humidity sensor. The indoor temperature sensor and the indoor humidity sensor can be set at the air inlet 111 of the air conditioner. The specific values ​​of the first set temperature, the second set temperature, and the set humidity are not limited and can be reasonably set as needed.

[0139] Of course, the method for determining the condensation condition is not limited thereto. For example, the outlet air temperature may be directly detected to replace the temperature of the indoor heat exchanger 3 , and the indoor temperature and indoor humidity may also be obtained by other methods.

[0140] In some exemplary embodiments, the air guide mechanism 2 is controlled according to the air outlet mode of the air conditioner to limit condensation at the air outlet, including:

[0141] Based on the air conditioner being in the first air outlet mode or the second air outlet mode, controlling the air guide mechanism 2 to maintain the current state;

[0142] Based on the air conditioner being in the third air outlet mode, the air guide mechanism 2 is controlled to operate to switch the air outlet mode.

[0143] Among them, the first air outlet mode is the downward air outlet mode, the second air outlet mode is the side air outlet mode, and the third air outlet mode is the double air outlet mode.

[0144] When the air conditioner is in the first air outlet mode, since the air guide plate assembly can completely close the second air outlet 152, effectively isolating the cold and hot air on both sides of the air guide plate assembly, condensation can be effectively avoided at the second air outlet 152, so the air guide mechanism 2 can maintain the current state without adjustment.

[0145] Similarly, when the air conditioner is in the second air outlet mode, since the air guide plate assembly can completely close the first air outlet 151, effectively isolating the cold and hot air on both sides of the air guide plate assembly, it can effectively avoid condensation at the first air outlet 151, so the air guide mechanism 2 can maintain the current state without adjustment.

[0146] When the air conditioner is in the third air outlet mode, the air volume at the first air outlet 151 is significantly reduced compared to the first air outlet mode under the same air volume, which will lead to uneven wind speed distribution, so that the area in the first air outlet 151 far away from the second air outlet 152 will produce a recirculation zone 19 (such as Fig.10 If the air conditioner is in the third air outlet mode for a long time, condensation will form at the first air outlet 151, causing dripping, such as condensation forming on the inner wall of the recirculation zone 19. Therefore, when the current working condition is in the set condensation working condition and the air conditioner is in the third air outlet mode, it is necessary to switch the air outlet mode to avoid condensation at the first air outlet 151.

[0147] In some exemplary embodiments, controlling the air guide mechanism 2 to switch the air outlet mode includes:

[0148] The air guide mechanism 2 is controlled to operate so that the air outlet mode of the air conditioner is switched from the third air outlet mode to the first air outlet mode.

[0149] On the one hand, this can maintain a strong wind feeling, which is conducive to ensuring the user's current temperature control needs; on the other hand, it is conducive to the rapid adjustment of the temperature of the area surrounding the air conditioner, and the current working conditions are improved by reducing the temperature difference between cold and hot air at the first air outlet 151, so as to reduce the risk of condensation at the first air outlet 151.

[0150] Of course, the air outlet mode of the air conditioner may also be switched to the second air outlet mode to avoid condensation at the first air outlet 151 .

[0151] In some exemplary embodiments, the control method further includes:

[0152] Based on the air outlet mode of the air conditioner being switched from the third air outlet mode to the first air outlet mode and running for the first set time, the air guide mechanism 2 is controlled to operate so that the air outlet mode of the air conditioner is switched from the first air outlet mode back to the third air outlet mode;

[0153] Based on the air conditioner switching back to the third air outlet mode from the first air outlet mode and running for the second set time, return to the step of controlling the air guide mechanism 2 to switch the air outlet mode of the air conditioner from the third air outlet mode to the first air outlet mode.

[0154] In other words, when the air conditioner switches to the first air outlet mode and runs for a period of time (first set time), it will switch back to the third air outlet mode to meet the user's full-area air outlet needs; when the air conditioner runs in the third air outlet mode for a period of time (second set time), it will switch back to the first air outlet mode. This cycle repeats, while ensuring the full-area air outlet needs, and avoiding condensation at the first air outlet 151 to cause dripping as much as possible.

[0155] In some exemplary embodiments, the control method further includes:

[0156] Before controlling the air guide mechanism 2 to operate to switch the air outlet mode, it is determined that the air conditioner operates in the third air outlet mode for a third set time period, and the step of controlling the air guide mechanism 2 to operate to switch the air outlet mode is performed.

[0157] In other words, when it is determined that the current working condition is the set condensation working condition and the air outlet mode of the air conditioner is the third air outlet mode, the air outlet mode is not switched immediately, but the air outlet mode is switched after the third air outlet mode has been running for a period of time (third set duration). This is because condensation is not generated immediately in the third air outlet mode, but only after a long period of operation. Therefore, the air outlet mode can be switched after the third air outlet mode has been running for a period of time (third set duration) to meet the user's full-area air outlet needs as much as possible.

[0158] Among them, the specific values ​​of the first set time length, the second set time length, and the third set time length are not restricted and can be reasonably set as needed.

[0159] In some embodiments, the third set time length is equal to the second set time length. In this way, when it is determined that the current working condition is the set condensation working condition and the air outlet mode of the air conditioner is the third air outlet mode, the air guide mechanism 2 can be operated periodically with the third set time length (the state corresponding to the third air outlet mode) + the first set time length (the state corresponding to the first air outlet mode) as a cycle.
