The water collection tray includes a water receiving section with a water receiving trough, which is positioned adjacent to the air outlet. A cold insulation structure is provided at the end of the water receiving section near the air outlet to reduce heat transfer between the water receiving section and the air outlet. By providing a cold insulation structure at the end of the water receiving section near the air outlet, this application reduces heat transfer between the water receiving section and the air outlet, effectively breaking the cold bridge between them.

[0034] In the above sectional structural diagram, the section lines are omitted, but this does not affect the overall structural representation. Detailed Implementation

[0035] The principles and features of this application are described below with reference to the accompanying drawings. The examples given are only for explaining this application and are not intended to limit the scope of this application.

[0036] Research has found that the reason why condensation and dripping water easily occur at the air outlet of air conditioners in related technologies is as follows: the water collection tray is located below the evaporator, and in cooling mode, it collects the low-temperature condensate dripping from the evaporator, resulting in a low temperature. Furthermore, the adjacent placement of the water collection tray and the air outlet creates a cold bridge, further lowering the temperature of the air outlet. Consequently, when the warmer air comes into contact with the air outlet, condensation occurs, causing dripping water.

[0037] Therefore, such as Figures 1 to 11 As shown in the figure, this application embodiment provides a water receiving tray 12, which is applied to an air conditioner. The air conditioner can be, but is not limited to, an air conditioner with dual air outlets.

[0038] like Figure 1 As shown, the air conditioner has an air outlet 120, and the air outlet 120 has an air outlet space 125. The air outlet 120 can be the lower air outlet of an air conditioner with dual air outlets, configured to direct airflow downwards. The air conditioner can also have a side air outlet, configured to direct airflow forwards.

[0039] like Figure 1 As shown, the water receiving tray 12 includes a water receiving portion 126. The water receiving portion 126 is provided with a water receiving trough 1260, which is arranged adjacent to the air outlet portion 120. A cold insulation structure 127 is provided at one end of the water receiving portion 126 near the air outlet portion 120 to reduce heat transfer between the water receiving portion 126 and the air outlet portion 120.

[0040] The water receiving tray 12 provided in this application embodiment has a cold insulation structure 127 at the end of the water receiving part 126 near the air outlet 120 to reduce heat transfer between the water receiving part 126 and the air outlet 120. This is equivalent to cutting off the cold bridge between the water receiving part 126 and the air outlet 120, thereby reducing the impact of the low temperature of the water receiving part 126 on the air outlet 120, which is conducive to increasing the temperature of the air outlet 120, reducing the risk of condensation and dripping water in the air outlet 120, and thus improving the user experience.

[0041] The air outlet 120 can be roughly prism-shaped, enclosing an air outlet space 125 that is also roughly prism-shaped, such as... Figure 1 As shown.

[0042] In some exemplary embodiments, such as Figure 6As shown, the cold insulation structure 127 includes a clearance portion 1270. The clearance portion 1270 is provided with a clearance gap. The position of the clearance gap can directly disconnect the water receiving portion 126 from the air outlet portion 120, thereby achieving an effective cold insulation effect.

[0043] In some exemplary embodiments, the clearance portion 1270 includes a plurality of ribs 1271 spaced apart along the length direction of the clearance, such as... Figure 5 As shown, the baffle 1271 is configured to connect with the air outlet 120. The space between adjacent baffles 1271 forms a clearance notch 1272, and the clearance notch includes multiple spaced clearance notches 1272, such as... Figure 5 As shown.

[0044] The baffle 1271 connects the water receiving part 126 and the air outlet 120, which helps to improve the connection strength between the water receiving part 126 and the air outlet 120, thereby improving the reliability of the air conditioner. The clearance notch 1272 can prevent cold bridges, thereby reducing heat transfer between the water receiving part 126 and the air outlet 120.

[0045] Of course, the clearance 1270 may not include the partition 1271, in which case the clearance gap can be a complete long strip gap.

[0046] In some exemplary embodiments, such as Figure 5 As shown, the cold insulation structure 127 also includes a receiving groove 1273 located above the rib 1271, with the opening of the receiving groove 1273 facing upwards. The cold insulation structure 127 also includes a first thermal insulation element 1274 at least partially embedded in the receiving groove 1273, such as... Figures 2 to 4 As shown. The first insulation element 1274 can be, but is not limited to, insulation foam strips. The receiving groove 1273 can be formed by the water receiving part 126, multiple baffles 1271, and the air outlet 120, as shown. Figure 5 As shown. The first insulation component 1274 can be fixed in the receiving groove 1273 by means of bonding, interference fit, etc.

[0047] The first insulation component 1274 can seal the gap between the water receiving part 126 and the air outlet part 120, thus isolating cold air and preventing air leakage at the gap. Furthermore, the first insulation component 1274 can also provide thermal insulation, reducing heat transfer between the water receiving part 126 and the air outlet part 120, thereby lowering the risk of condensation at the air outlet part 120.

[0048] In some exemplary embodiments, such as Figure 1 As shown, the water receiving tray 12 also includes an air outlet 120, which is connected to the water receiving tray 126.

[0049] In other words, in this embodiment of the application, the water tray 12 integrates an air outlet 120 in addition to the water receiving part 126, so it has both the function of receiving condensate and the function of air outlet, which can better meet the needs of air conditioners with dual air outlets (bottom air outlet and side water outlet) for receiving condensate and bottom air outlet.

[0050] In some embodiments, the air outlet 120 and the water receiving part 126 can be configured as an integral structure. This improves the connection strength and reliability of the fit between the water receiving part 126 and the air outlet 120, and eliminates the assembly process between the air outlet 120 and the water receiving part 126. For example, if the air outlet 120 and the water receiving part 126 can be integrally molded by injection molding, the aforementioned partition 1271 can also be integrally molded together, facilitating the reasonable arrangement of the shapes of structures such as the water receiving part 126, the air outlet 120, and the clearance part 1270 as needed.

[0051] In other embodiments, the air outlet 120 and the water receiving part 126 can also be configured as separate assembly structures. For example, the water receiving part 126 and the air outlet 120 can be formed separately and then assembled together by fasteners, snap-fitting, or other methods. In this case, the clearance part 1270 may not include the partition 1271, and the clearance gap can be a complete elongated gap, within which the first insulation component 1274 can be fixed.

[0052] Studies have found that another reason why condensation easily forms in the air outlet 120 is that the shapes (mainly the longitudinal cross-sectional profiles) of the water receiving part 126 and the air outlet 120 have a significant impact on the wind speed distribution within the air outlet space 125 (e.g., Figure 12 As shown), this can easily lead to a backflow zone 19 within the air outlet space 125 (such as...). Figure 20 In the area indicated by the small arrows, external hot air easily flows back into the recirculation zone 19, contacting the low-temperature inner wall of the air outlet 120 and causing condensation. The recirculation zone 19 tends to appear near the inner wall of the air outlet 120 close to the water receiving section 126 (i.e., the first air outlet wall 1251 described below). Therefore, this application has also improved the shapes of the water receiving section 126, the air outlet 120, and the transition surface 1275 to reduce the risk of recirculation zone 19 formation and improve the anti-condensation effect.

[0053] In some exemplary embodiments, the top of the first insulation member 1274 protrudes from the receiving groove 1273, such as... Figure 2 As shown. Furthermore, the portion of the first insulation member 1274 located outside the receiving groove 1273 is configured as a transition surface 1275. The cross-sectional profile of the transition surface 1275 is configured as an arc shape so that the transition surface 1275 can smoothly transition with the inner wall of the adjacent water receiving portion 126 (i.e., the first side wall 1261) and the inner wall of the adjacent air outlet portion 120 (i.e., the first air outlet wall 1251 described below), as shown. Figure 10 As shown.

[0054] In this way, the transition surface 1275 forms part of the wall of the air duct 14, which can play a guiding role, which is conducive to the smooth transition of airflow from the water receiving part 126 to the air outlet 120, thereby reducing wind resistance and increasing air volume. Furthermore, this arrangement allows some airflow to flow along the inner wall of the adjacent air outlet 120 (i.e., the first air outlet wall 1251 below) after passing through the transition surface 1275, thereby reducing the risk of condensation forming on the inner wall due to the backflow zone 19 in the vicinity of the inner wall (i.e., the first air outlet wall 1251 below).

[0055] In some exemplary embodiments, such as Figure 10 As shown, the inner wall of the water receiving part 126 includes a first side wall 1261. The inner wall of the air outlet part 120 includes a first air outlet wall 1251. A heat insulation structure 127 is located between the first side wall 1261 and the first air outlet wall 1251 to reduce heat transfer between the first side wall 1261 and the first air outlet wall 1251.

[0056] The air outlet 120 can be roughly prism-shaped, enclosing an air outlet space 125 that is also roughly prism-shaped. The inner walls of the air outlet 120 can include a first air outlet wall 1251, a second air outlet wall 1252, a third air outlet wall 1253, and a fourth air outlet wall 1254 connected sequentially from end to end. Figures 5 to 7 As shown. The first air outlet wall 1251 and the third air outlet wall 1253 are arranged relatively apart and have equal or substantially equal lengths, and the second air outlet wall 1252 and the fourth air outlet wall 1254 are arranged relatively apart and have equal or substantially equal lengths. In addition, the distance between the first air outlet wall 1251 and the third air outlet wall 1253 is less than the distance between the second air outlet wall 1252 and the fourth air outlet wall 1254. Therefore, the first air outlet wall 1251 and the third air outlet wall 1253 are the inner sidewalls of the air outlet space 125, and the second air outlet wall 1252 and the fourth air outlet wall 1254 are the inner sidewalls of the air outlet space 125.

[0057] Among the inner sidewalls of the air outlet 120, the first air outlet wall 1251 and the first sidewall 1261 are closest to each other. Therefore, the cold bridge is mainly formed between the first air outlet wall 1251 and the first sidewall 1261, and the first air outlet wall 1251 has the lowest temperature and is most prone to condensation. Therefore, the cold insulation structure 127 is set between the first sidewall 1261 and the first air outlet wall 1251, which can effectively reduce the heat transfer between the first sidewall 1261 and the first air outlet wall 1251, and effectively reduce the risk of condensation in the air outlet 120.

[0058] In some embodiments, along the direction from the first sidewall 1261 to the first air outlet wall 1251, the first sidewall 1261 extends obliquely upward and towards the first air outlet wall 1251, such as... Figure 10 As shown. In other words, the first sidewall 1261 is inclined, and the upper end of the first sidewall 1261 extends inclined towards the first air outlet wall 1251.

[0059] In this way, the first sidewall 1261 can also play a guiding role, which is conducive to guiding the airflow to the air outlet 120 and improving the wind speed distribution in the air outlet space 125, making the wind speed distribution in the air outlet space 125 more uniform, thereby reducing the size of the backflow zone 19 generated in the air outlet space 125, reducing the risk of backflow zone 19 generated in the air outlet space 125, and thus further reducing the risk of condensation in the air outlet 120.

[0060] In some exemplary embodiments, the bottom wall 1266 of the water receiving tank 1260 is provided with a guide slope 1267, such as... Figure 10 As shown. The guide slope 1267 is connected to the first sidewall 1261 and extends in an upward and closer direction to the first air outlet wall 1251 along the direction from the first sidewall 1261. The angle of inclination of the guide slope 1267 relative to the horizontal plane is smaller than the angle of inclination of the first sidewall 1261 relative to the horizontal plane. Figure 10 As shown. In other words, the guide slope 1267 is inclined, and the upper end of the guide slope 1267 extends inclined towards the first air outlet wall 1251.

[0061] In this way, the guide slope 1267 can also play a guiding role, which is conducive to guiding the airflow to the first side wall 1261 and the air outlet 120, and further improving the wind speed distribution in the air outlet space 125, so as to further reduce the size of the backflow zone 19 generated in the air outlet space 125, reduce the risk of backflow zone 19 being generated in the air outlet space 125, and thus further reduce the risk of condensation in the air outlet 120.

[0062] In some exemplary embodiments, such as Figure 10 and Figure 11 As shown, the first air outlet wall 1251 is configured to smoothly transition from the upper end to the lower end. The middle part of the first air outlet wall 1251 in the height direction is configured as an arc-shaped curved surface that protrudes away from the first side wall 1261. The maximum horizontal distance between the arc-shaped curved surface and the upper end of the first air outlet wall 1251 is greater than or equal to the horizontal distance between the lower end and the upper end of the first air outlet wall 1251.

[0063] Among them, such as Figure 11As shown, the maximum horizontal distance between the curved surface and the upper end of the first air outlet wall 1251 is equal to (the maximum horizontal distance AB between the curved surface and the top A of the transition surface 1275) - (the horizontal distance between the top A of the transition surface 1275 and the upper end of the first air outlet wall 1251); the horizontal distance between the lower end and the upper end of the first air outlet wall 1251 is equal to (the horizontal distance AC between the lower end and the top A of the transition surface 1275) - (the horizontal distance between the top A of the transition surface 1275 and the upper end of the first air outlet wall 1251). Therefore, when the top A of the transition surface 1275 is taken as the reference, the horizontal distance AB between the curved surface and the top A of the transition surface 1275 is greater than or equal to the horizontal distance AC between the lower end of the first air outlet wall 1251 and the top A of the transition surface 1275.

[0064] In this way, the first air outlet wall 1251 can also play a guiding role, which helps to guide part of the airflow to flow from the upper end to the lower end of the first air outlet wall 1251, thereby further reducing the size of the backflow zone 19 generated in the air outlet space 125 and further reducing the risk of backflow zone 19 generated in the air outlet space 125, thus helping to further reduce the risk of condensation in the air outlet 120.

[0065] In some exemplary embodiments, such as Figure 10 As shown, the upper end of the first sidewall 1261 and the upper end of the first air outlet wall 1251 are connected by an arc transition surface 1275. The radius R of the transition surface 1275 is greater than or equal to 5 mm.

[0066] If the radius of the transition surface 1275 is too small, it will be difficult to effectively guide airflow and prevent condensation; if the radius of the transition surface 1275 is too large, the size of the water tray 12 will be too large. Therefore, setting the radius of the transition surface 1275 within the above-mentioned range can achieve both good airflow guidance and anti-condensation effects, while also taking into account the overall size of the water tray 12, which is beneficial to reducing the size of the air conditioner.

[0067] Of course, the radius of the transition surface 1275 is not limited to the above range and can be adjusted as needed.

[0068] In some exemplary embodiments, the height of the first sidewall 1261 is less than the height of the other sidewalls of the water receiving tank 1260. Therefore, as... Figure 10 As shown, the vertical distance H1 between the top of the transition surface 1275 and the lowest point of the bottom wall 1266 of the water receiving tank 1260 determines the highest water level that the water receiving tank 1260 can accommodate.

[0069] The larger H1 is, the higher the maximum water level that the water receiving tank 1260 can hold, and the greater the safety margin for water receiving, but the greater the resistance to the air duct 14. The smaller H1 is, the less resistance to the air duct 14, but the lower the maximum water level that the water receiving tank 1260 can hold, and the smaller the safety margin for water receiving.

[0070] Research shows that when the vertical distance H1 between the top of the transition surface 1275 and the lowest point of the bottom wall 1266 of the water receiving trough 1260 satisfies 15mm≤H1≤35mm (e.g., 15mm, 20mm, 25mm, 30mm, 35mm, etc.), it can take into account both the water receiving needs of the air conditioner and the resistance of the air duct 14, thus better meeting the water receiving and air output needs of the air conditioner.

[0071] Of course, the size of H1 is not limited to the above range and can be adjusted as needed.

[0072] In some exemplary embodiments, such as Figure 10 As shown, the air outlet space 125 has an upper port and a lower port that are spaced apart from each other. Along the airflow direction of the air outlet space 125, the upper port is located upstream of the lower port. The width W2 of the upper port is greater than the width W1 of the lower port.

[0073] In some embodiments, the inner wall of the air outlet 120 includes a third air outlet wall 1253 disposed at a distance from the first air outlet wall 1251, such as Figure 5 and Figure 8 As shown, the third air outlet wall 1253 is configured as a straight surface extending in the vertical direction.

[0074] This allows the airflow entering the outlet space 125 from the upper port to tend to converge within the outlet space 125, facilitating some airflow to flow downwards along the first outlet wall 1251, thus improving the wind speed distribution and further reducing the risk of backflow zone 19 forming within the outlet space 125, which in turn helps to further reduce the risk of condensation forming in the outlet section 120.

[0075] In some embodiments, such as Figure 10 As shown, W1 and W2 satisfy: 40mm≤W1≤70mm, W2≥W1+5mm.

[0076] If W1 is too large, it will not be conducive to the uniform distribution of airflow velocity within the outlet space of 125; if W1 is too small, it will result in insufficient airflow. If the difference between W2 and W1 is too large, it will result in insufficient airflow; if the difference between W2 and W1 is too small, the effect of improving airflow velocity distribution will not be significant.

[0077] Research shows that W1 and W2, within the aforementioned range, can balance the effects of improving wind speed distribution and meeting air supply requirements, thus effectively satisfying the air conditioning's anti-condensation and air supply needs.

[0078] In some exemplary embodiments, the air outlet 120 and the water receiving part 126 together enclose a clearance space 128 located on the lower side of the cold insulation structure 127, such as... Figure 5 As shown. The water tray 12 also includes a second insulation element 1281 filled in the clearance space 128, such as Figure 4 As shown. This further isolates the heat transfer between the water receiving part 126 and the air outlet part 120, which helps to further improve the anti-condensation effect.

[0079] In some exemplary embodiments, the outer wall of the water receiving part 126 and the outer wall of the air outlet 120 are covered with a third insulation member 129, such as Figure 4 and Figure 9 As shown. This design provides good insulation for the water inlet section 126 and the air outlet section 120, and also helps to further improve the anti-condensation effect.

[0080] In some exemplary embodiments, the upper end of the air outlet 120 is also provided with a sealing part, which is arranged circumferentially along the upper port of the air outlet space 125.

[0081] In this way, for an air conditioner with dual air outlets, when the lower air outlet does not need to output air and the air conditioner only needs to output air from the side, the sealing part can be sealed and matched with the surrounding components (such as the air guide plate, air guide support 13, etc.) to completely close the air outlet space 125. This is beneficial to prevent air leakage and condensation in the air outlet space 125, and also to prevent air leakage and whistling.

[0082] In some embodiments, such as Figure 1 As shown, the sealing portion includes a first overlapping edge 121, a second overlapping edge 122, a third overlapping edge 123, and a ninth overlapping edge 1241 arranged sequentially along the circumference of the upper port of the air outlet space 125. The first overlapping edge 121 and the third overlapping edge 123 are arranged at intervals relative to each other and have equal or substantially equal lengths. The second overlapping edge 122 and the ninth overlapping edge 1241 are also arranged at intervals relative to each other and have equal or substantially equal lengths. The distance between the first overlapping edge 121 and the third overlapping edge 123 is greater than the distance between the second overlapping edge 122 and the ninth overlapping edge 1241. Therefore, the first overlapping edge 121 and the third overlapping edge 123 are arranged along the shorter side of the air outlet portion 120, and the second overlapping edge 122 and the ninth overlapping edge 1241 are arranged along the longer side of the air outlet portion 120.

[0083] In some embodiments, such as Figures 2 to 4 As shown, the first overlapping edge 121, the second overlapping edge 122, and the third overlapping edge 123 are configured to overlap and seal with the first air guide plate 21 described below. The ninth overlapping edge 1241 is configured to seal with the air guide support 13 described below, as... Figure 4 As shown.

[0084] In some exemplary embodiments, the air outlet 120 is located at the end of the water receiving tray 12 in the width direction, such as... Figure 1 As shown. Compared to placing the air outlet 120 in the middle of the width direction of the water receiving tray 12, the structure of the water receiving tray 12 in this design is simpler and easier to process and form.

[0085] The air outlet 120 can be located downstream of the water receiving section 126. In this way, the distance between the air outlet 120 and the side air outlet of the air conditioner is small, which makes it easier for the air outlet 120 and the side air outlet to share the same air guide plate (such as the first air guide plate 21 described below), thereby simplifying the air guiding structure of the air conditioner.

[0086] In some embodiments, such as Figure 1 As shown, the water receiving tank 1260 includes a main body 1268. An air outlet space 125 is located on one side of the main body 1268 in the width direction, and the length of the air outlet space 125 is less than or equal to the length of the main body 1268. This helps improve the safety of the water receiving capacity of the water receiving tank 1260.

[0087] In some embodiments, such as Figure 1 As shown, the length of the air outlet space 125 is less than the length of the water receiving tank body 1268. The water receiving tank 1260 also includes an end groove 1269 that communicates with the water receiving tank body 1268. The end groove 1269 is located on one or both sides of the length direction of the air outlet space 125.

[0088] This design allows for a larger volume in the water receiving trough 1260, which improves the safety of the water retention capacity. Additionally, it makes the structure of the water receiving tray 12 more regular, facilitating both processing and assembly.

[0089] When the water receiving trough 1260 only includes the water receiving trough body 1268, the side walls of the water receiving trough 1260 may include a first side wall 1261, a second side wall 1262, a third side wall 1263 and a fourth side wall 1264.

[0090] like Figure 1 As shown, when the water receiving tank 1260 also includes an end groove 1269, the side wall of the water receiving tank 1260 also includes one (the number of end grooves 1269 is one) or two (the number of end grooves 1269 is two) relatively short outer side wall of the air outlet 120, namely the fifth side wall 1265.

[0091] like Figures 13 to 21 As shown, this application embodiment also provides an air conditioner, including a housing 1, which includes a water receiving tray 12 of any of the above embodiments, and thus has all the above-mentioned beneficial effects, which will not be repeated here.

[0092] In some exemplary embodiments, such as Figure 13 and Figure 17 As shown, the housing 1 also includes an outer shell 11 and an air guide support 13. The air conditioner also includes an air guide fan 4. The air guide support 13 is connected to the outer shell 11, and the water receiving tray 12 is connected to the outer shell 11 and the air guide support 13. An air duct 14 is provided inside the outer shell 11.

[0093] like Figure 14 As shown, the air outlet 120 and the air guide support 13 together form a first air vent 151 that communicates with the air outlet space 125. The air guide support 13 is provided with a second air vent 152. The first air vent 151 and the second air vent 152 have different air outlet directions. The first air vent 151 is configured to communicate with the air duct 14 to form a first air outlet channel, and the second air vent 152 is configured to communicate with the air duct 14 to form a second air outlet channel. In other words, when the first air vent 151 is connected to the air duct 14, the air outlet channel formed by their connection is the first air outlet channel. In other words, when the second air vent 152 is connected to the air duct 14, the air outlet channel formed by their connection is the second air outlet channel.

[0094] like Figure 21 As shown, an indoor heat exchanger 3 and a fan 4 can be installed inside the air duct 14. When the fan 4 rotates, indoor air enters the air duct 14, exchanges heat with the indoor heat exchanger 3, and is then discharged into the indoor space through the air outlet channel, thus regulating the temperature of the indoor air.

[0095] like Figure 21 As shown, the air guide fan 4 includes a first air guide plate 21 and a second air guide plate 22 located inside the housing 1 and movably connected to the housing 1. The first air guide plate 21 and the second air guide plate 22 cooperate 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 where the first air outlet channel is open and the second air outlet channel is closed (e.g., Figure 17 As shown), the second air outlet mode (such as) where the first air outlet channel is disconnected and the second air outlet channel is open. Figure 13 As shown), and a third air outlet mode in which both the first and second air outlet channels are open (as shown). Figure 20 (As shown).

[0096] The air conditioner provided in this application embodiment has three air outlet modes by setting a first air outlet 151 and a second air outlet 152 with different air outlet directions, as well as a first air guide plate 21 and a second air guide plate 22 that cooperate with the first air outlet 151 and the second air outlet 152. This allows the air conditioner to have three air outlet modes, which makes it convenient for users to choose the air outlet mode according to their needs, which helps to meet the different air outlet needs of users and thus improves the user experience.

[0097] Furthermore, the first air vent 151 and the second air vent 152 only require the cooperation of the first air guide plate 21 and the second air guide plate 22 to control their opening and closing and achieve the switching of three air outlet modes, without the need for other wind-blocking or air-guiding components (such as movable volutes or other deformable or movable wind-blocking mechanisms), which helps to simplify the structure of the air conditioner and reduce production costs.

[0098] In this embodiment of the application, the air conditioner can be the indoor unit of a split air conditioner, such as a duct-type indoor unit or a wall-mounted indoor unit, or it can be a split air conditioner that includes an indoor unit and an outdoor unit, or it can be an integrated air conditioner.

[0099] In some embodiments, the first air vent 151 can be a downdraft vent, discharging air downwards; the second air vent 152 can be a side vent, discharging air horizontally. Therefore, the first air outlet mode is a downdraft mode, the second air outlet mode is a downdraft mode, and the third air outlet mode is a dual-air outlet mode. When the user needs rapid cooling or rapid heating, they can select the first air outlet mode, in which case the airflow will be discharged downwards through the first air outlet channel. Figure 17 As shown, this facilitates rapid temperature reduction or increase in the area below. When users want to avoid direct airflow, they can select the second air outlet mode, in which case the airflow is discharged laterally through the second air outlet channel, such as... Figure 14 As shown, this design facilitates airflow over a long distance, avoiding direct airflow onto the user. When the user desires uniform cooling or heating throughout the entire area, they can select the third airflow mode, in which case the airflow is blown out through both the first and second airflow channels, as shown. Figure 20 As shown, it can quickly adjust the temperature of the nearby area below, and it can also deliver air over long distances, enabling rapid temperature adjustment of distant areas as well.

[0100] In related technologies, ordinary central air conditioning duct-type indoor units are typically embedded in the ceiling, with one air inlet and one air outlet, usually employing a bottom air intake and side air outlet configuration with an engineering grille (fixed air outlet direction). However, this air delivery method prevents the heated air from reaching the ground, resulting in a large air delivery blind spot and significant temperature differences between near and far areas. Some products are equipped with electric panels (adjustable air outlet direction) to adjust the air outlet direction, but these have disadvantages such as high cost, difficulty in home decoration matching, and installation difficulties, resulting in a relatively low actual standard installation rate. Some products use a bottom air outlet configuration, but this has the problem of the cooling air blowing directly onto people, leading to lower product acceptance.

[0101] The air conditioner provided in this application embodiment has two air outlets with different airflow directions, enabling three different airflow modes. Users can choose according to their needs. The first airflow mode solves the problem of hot air not reaching the ground in heating mode; the second airflow mode solves the problem of cold air blowing directly on people in cooling mode; and the third airflow mode solves the problems of large airflow blind spots and large temperature differences between near and far, effectively addressing the pain points of existing duct-type indoor units. Furthermore, this air conditioner can be paired with a standard engineering grille for better coordination with home décor, making it popular with users; or it can be paired with an electric control panel to further enhance the user experience.

[0102] In some exemplary embodiments, such as Figure 13 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.

[0103] The first air guide plate 21 is rotatably connected to the housing 1 and is configured to be in a first position relative to the housing 1, where the first air outlet 151 is closed and the second sub-air outlet 1522 is open (e.g., ...). Figure 13 (As shown), open the first air vent 151 and the second sub-air vent 1522 to the second position (as shown). Figure 20 (As shown), the third position where the first air vent 151 is opened and the second sub-air vent 1522 is closed (as shown) Figure 17 Rotate between (as shown).

[0104] The second air guide plate 22 is rotatably connected to the housing 1, and is configured to be in a fourth position relative to the housing 1 when the first sub-air vent 1521 is closed (e.g., Figure 17 (as shown) and the fifth position of opening the first sub-vent 1521 (as shown) Figure 13 Rotate between (as shown).

[0105] 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 vent 151 is open and the second air vent 152 is closed, and the air conditioner is in the first air outlet mode. Figure 17 As shown.

[0106] 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 vent 151 is closed and the second air vent 152 is open, and the air conditioner is in the second air outlet mode. Figure 13 and Figure 14 As shown.

[0107] 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 vent 151 opens, the second air vent 152 opens, and the air conditioner is in the third air outlet mode. Figure 20 As shown.

[0108] In other words, the first air guide plate 21 is used to control the opening and closing of the first air vent 151 and the second sub-air vent 1522 (a part of the second air vent 152). The second air guide plate 22 is used to control the opening and closing of the first sub-air vent 1521 (the other part of the second air vent 152). Therefore, the first air guide plate 21 and the second air guide plate 22 jointly control the opening and closing of the second air vent 152. In this way, the widths of the first air vent 151 and the second air vent 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 beneficial to optimizing the structural layout of the air conditioner and reducing its size.

[0109] Of course, the first air guide plate 21 and the second air guide plate 22 can also control the opening and closing of the first air outlet 151 and the second air outlet 152 respectively.

[0110] In some embodiments, the lower port of the air outlet space 125 is connected to the first air outlet 151 to form a first air outlet. The first air outlet is arranged horizontally. A first air passage is formed between the first air outlet 151 and the first air outlet. The air guide support 13 is also provided with a second air outlet that is connected to the second air outlet 152, and a second air passage is formed between the second air outlet 152 and the second air outlet. This facilitates the reasonable setting of the positions of the first air outlet 151 and the second air outlet 152, as well as the shapes of the first air guide plate 21 and the second air guide plate 22, as needed, which is beneficial to optimizing the structural layout of the air conditioner without affecting its appearance.

[0111] The first air outlet is set horizontally, and the second air outlet is set vertically. For example, if the first air outlet is set downwards and the second air outlet is set forwards, 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 dual air outlet mode.

[0112] In some exemplary embodiments, one end of the first air guide plate 21 in the width direction is provided with a first rotating part 211 that is rotatably connected to the housing 1, such as... Figure 14 As shown, the first rotating part 211 is located between the first air vent 151 and the second sub-air vent 1522. The second air guide plate 22 has a second rotating part 221 rotatably connected to the housing 1 at one or both ends in the width direction. Figure 17 As shown.

[0113] In other words, the rotating part of the first air guide plate 21 is located at one end of the width direction of the first air guide plate 21, which facilitates the rotation of the first air guide plate 21 between the first air outlet 151 and the second sub-air outlet 1522. When the first air outlet 151 is closed by rotation, the second sub-air outlet 1522 is opened, and the first air guide plate 21 is in the first position; when the second sub-air outlet 1522 is closed by rotation, the first air outlet 151 is opened, and the air guide plate is in the third position; when 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 open, and the air guide plate is in the second position. The opening angle of the first air guide plate 21 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 surfaces of the first air guide plate 21 to the first air outlet 151 and the second sub-air outlet 1522 respectively, thereby reducing the wind resistance generated by the first air guide plate 21.

[0114] The position of the rotating part of the second air guide plate 22 is not restricted; it can be set at one end of the width direction of the second air guide plate 22 or between the two ends of the width direction of the second air guide plate 22.

[0115] In some exemplary embodiments, the air guide support 13 is provided with a first arc-shaped groove 132 and a second arc-shaped groove 133, such as Figure 14 and Figure 17 As shown. The first arc-shaped groove 132 is configured to mount the first rotating part 211 and limit the rotation amplitude of the first rotating part 211, and the second arc-shaped groove 133 is configured to mount the second rotating part 221 and limit the rotation amplitude of the second rotating part 221.

[0116] The shapes of the first rotating part 211 and the second rotating part 221 are adapted to the first arc-shaped groove 132 and the second arc-shaped groove 133, respectively. This facilitates limiting the rotation angle of the first air guide plate 21 and the second air guide plate 22 through mechanical limiting, and also facilitates overlapping sealing.

[0117] In some exemplary embodiments, the water receiving tray 12 is provided with a first overlapping edge 121, a second overlapping edge 122, and a third overlapping edge 123 arranged sequentially along the circumference of the first air vent 151, such as... Figures 14 to 16 As shown. The air guide support 13 is provided with a fourth overlapping edge 134 that is opposite to the second overlapping edge 122 and connected to the first overlapping edge 121 and the third overlapping edge 123, and a fifth overlapping edge 135, a sixth overlapping edge 136, a seventh overlapping edge 137 and an eighth overlapping edge 138 arranged sequentially along the circumference of the second air outlet 152, as follows. Figures 17 to 19 As shown.

[0118] Based on the first air guide plate 21 being located in 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, such as... Figures 14 to 16 As shown.

[0119] Based on the fact that the first air guide plate 21 is located in the third position, the circumferential end of the first air guide plate 21 overlaps and seals with the fifth overlapping edge 135, the sixth overlapping edge 136, the end of the second air guide plate 22 near the first air guide plate 21, and the eighth overlapping edge 138, as shown. Figures 17 to 19 As shown.

[0120] Based on the fact that the second air guide plate 22 is located in the fourth position, the circumferential end of the second air guide plate 22 overlaps and seals with the seventh overlapping edge 137, the sixth overlapping edge 136, the end of the first air guide plate 21 near the second air guide plate 22, and the eighth overlapping edge 138, as shown. Figures 17 to 19 As shown.

[0121] The first air guide plate 21 may have two parallel short sides and two parallel long sides. The long sides and short sides may be perpendicular to each other, and the short sides may be straight or curved. The first overlapping edge 121 and the third overlapping edge 123 may be short sides, used for overlapping and sealing with the two short sides of the first air guide plate 21. The second overlapping edge 122 and the fourth overlapping edge 134 may be long sides, used for overlapping and sealing with the two long sides of the first air guide plate 21.

[0122] The second air guide plate 22 may have two parallel short sides and two parallel long sides. The long sides and short sides may be perpendicular to each other, and the short sides may be straight or curved. The sixth overlapping side 136 and the eighth overlapping side 138 may be short sides, 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, used to overlap and seal with the two long sides of the second air guide plate 22.

[0123] 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 prismatic structures (in line contact with the first air guide plate 21 / second air guide plate 22) or planar structures (in surface contact with the first air guide plate 21 / second air guide plate 22), as long as they can achieve overlapping sealing.

[0124] In some embodiments, the water receiving tray 12 is further provided with a ninth overlapping edge 1241 that is spaced apart from the second overlapping edge 122, such as Figure 4 As shown. The ninth overlapping edge 1241 is sealed to the end of the air guide support 13 near the water receiving tray 12.

[0125] The second overlapping edge 122 can be provided on the first insulation member 1274, that is, a part of the first insulation member 1274 forms the second overlapping edge 122. Therefore, the first overlapping edge 121, the second overlapping edge 122 and the third overlapping edge 123 can overlap and seal with the first air guide plate 21 when the air conditioner is in the second air outlet mode. The end of the first air guide plate 21 that is not overlapped and sealed with the air outlet 120 is sealed with the air guide support 13, thereby achieving a complete seal on the first air outlet 151.

[0126] like Figure 4 and Figure 8 As shown, the water receiving tray 12 may be provided with a supporting step 124, which is located on the outer side of the upper port of the air outlet space 125. The bottom of the air guide support 13 may be provided with a supporting part 131, such as... Figure 4 As shown, the support part 131 is supported on the support step 124 and together with the water receiving tray 12 forms the first air vent 151. The first rotating part 211 of the first air guide plate 21 can be rotatably connected to the support part 131 of the air guide support 13. The ninth overlapping edge 1241 is provided on the support step 124. The support part 131 is flush with the third air outlet wall 1253. The space between the upper ends of the support part 131 and the first air outlet wall 1251 forms the first air vent 151.

[0127] like Figure 2 and Figure 3 As shown, the first overlapping edge 121 and the second overlapping edge 122 can be set in an arc shape to facilitate overlapping and sealing with the arc-shaped first air guide plate 21.

[0128] In some exemplary embodiments, such as Figures 14 to 19 As shown, the first air guide plate 21 and the second air guide plate 22 are provided with sealing edges 25 at their circumferential ends. The sealing edges 25 are configured to overlap and seal with the overlapping edges on the outer circumferential side of the corresponding air outlet, so that the first air guide plate 21 and / or the second air guide plate 22 close and seal the corresponding air outlet.

[0129] The sealing edge 25 can be a prismatic structure (for line contact) or a planar structure (for surface contact); the overlapping edge can be a prismatic structure (for line contact) or a planar structure (for surface contact), as long as it can achieve overlapping sealing.

[0130] Furthermore, the sealing edge 25 and the overlapping edge can be in hard contact, meaning that both the sealing edge 25 and the overlapping edge are rigid structures (such as plastic or metal structures), and a seal is formed through the overlap of these rigid structures. Alternatively, the sealing edge 25 and the overlapping edge can be in soft contact, meaning that at least one of the sealing edge 25 and the overlapping edge is a soft structure (such as silicone, rubber, or other soft sealing strips, or insulation cotton), and a seal is formed through the overlap of these soft structures or the overlap of a soft structure with a rigid structure.

[0131] In some exemplary embodiments, such as Figure 17 As shown, the air guide support 13 is provided with a receiving groove 139. Since the second air guide plate 22 is located in the fifth position, at least a portion of the second air guide plate 22 is embedded in the receiving groove 139, so that one side of the second air guide plate 22 forms part of the channel wall of the second air outlet channel. This helps to reduce the wind resistance generated by the second air guide plate 22 and helps to increase the air volume in the second and third air outlet modes.

[0132] In some exemplary embodiments, when the air conditioner is in the third air outlet mode, under the same air volume, the air volume at the first air outlet 151 is significantly reduced compared to the first air outlet mode, which leads to uneven air velocity distribution and causes a backflow zone 19 to be generated in the area of ​​the first air outlet 151 that is far from the second air outlet 152 (e.g., Figure 20 (The area indicated by the small and medium arrows) will be where hot and cold air meet in the first air outlet 151. When the air conditioner is in the third air outlet mode for a long time, condensation will form at the first air outlet 151, causing water to drip, for example, condensation will form on the inner wall of the return flow area 19, causing water to drip.

[0133] Therefore, when the current operating condition is a set condensation condition (e.g., indoor temperature greater than or equal to the first set temperature, indoor humidity greater than or equal to the set humidity, and the temperature of the indoor heat exchanger 3 of the air conditioner less than or equal to the second set temperature) and the air conditioner is in the third air outlet mode, the air outlet mode can be switched to avoid condensation at the first air outlet 151. For example, after running in the third air outlet mode for a period of time (the third set duration), it can be switched to the first air outlet mode for a period of time (the first set duration), and then switched back to the third air outlet mode to meet the user's need for airflow throughout the entire area; after the air conditioner runs in the third air outlet mode for a period of time (the second set duration), it will switch back to the first air outlet mode. This cycle repeats, ensuring airflow throughout the entire area while minimizing condensation and dripping at the first air outlet 151.

[0134] In this embodiment of the application, the air conditioner can be the indoor unit of a split air conditioner, such as a duct-type indoor unit or a wall-mounted indoor unit, or it can be a split air conditioner that includes an indoor unit and an outdoor unit, or it can be an integrated air conditioner.
