[0035] 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.

[0036] Research has found that in related technologies, the reason why the air outlet of the air conditioner is prone to condensation and dripping is that the water tank is located below the evaporator, and in cooling mode, it collects low-temperature condensed water dripping from the evaporator, resulting in a lower temperature. The water tank is adjacent to the air outlet, resulting in a cold bridge between the water tank and the air outlet, making the air outlet temperature lower. In this way, when the higher temperature air contacts the air outlet, condensation will occur, causing dripping.

[0037] For this reason, Figures 1 to 11 As shown, the embodiment of the present application 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 is provided with an air outlet 120, and the air outlet 120 is provided with an air outlet space 125. The air outlet 120 can be a lower air outlet of an air conditioner with double air outlets, which is configured to discharge air downward. The air conditioner can also have a side air outlet, which is configured to discharge air forward.

[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 groove 1260, and the water receiving groove 1260 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 close to 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 the embodiment of the present application is provided with a cold insulation structure 127 at one end of the water receiving portion 126 close to the air outlet portion 120 to reduce the heat transfer between the water receiving portion 126 and the air outlet portion 120, which is equivalent to cutting off the cold bridge between the water receiving portion 126 and the air outlet portion 120, thereby reducing the influence of the low temperature of the water receiving portion 126 on the air outlet portion 120, which is beneficial to increase the temperature of the air outlet portion 120, and reduce the risk of condensation in the air outlet portion 120 causing dripping, and further beneficial to improving the user experience.

[0041] The air outlet portion 120 may be substantially in the shape of a quadrangular prism, enclosing a substantially quadrangular prism-shaped air outlet space 125. Figure 1 shown.

[0042] In some exemplary embodiments, Figure 6As shown, the cold-insulating structure 127 includes a space-avoiding portion 1270. The space-avoiding portion 1270 is provided with a space-avoiding gap. The position of the space-avoiding gap can directly disconnect the water receiving portion 126 from the air outlet portion 120, thereby playing an effective cold-insulating role.

[0043] In some exemplary embodiments, the space-avoiding portion 1270 includes a plurality of spacer ribs 1271 spaced apart along the length direction of the space-avoiding gap. Figure 5 As shown, the partition ribs 1271 are arranged to be connected to the air outlet 120. The space between adjacent partition ribs 1271 forms an avoidance gap 1272, and the avoidance gap includes a plurality of avoidance gaps 1272 arranged at intervals, such as Figure 5 shown.

[0044] The ribs 1271 can connect the water receiving portion 126 and the air outlet portion 120, which is beneficial to improve the connection strength between the water receiving portion 126 and the air outlet portion 120, thereby improving the reliability of the air conditioner. The avoidance gap 1272 can achieve the function of isolating the cold bridge to reduce the heat transfer between the water receiving portion 126 and the air outlet portion 120.

[0045] Of course, the avoidance portion 1270 may not include the partition ribs 1271, and the avoidance gap may be a complete long strip-shaped gap.

[0046] In some exemplary embodiments, Figure 5 As shown, the cold insulation structure 127 further includes a receiving groove 1273 located on the upper side of the insulation rib 1271, and the receiving groove 1273 opens upward. The cold insulation structure 127 further includes a first heat preservation member 1274 at least partially embedded in the receiving groove 1273, as shown in FIG. Figures 2 to 4 The first heat-insulating member 1274 may be, but is not limited to, a heat-insulating foam strip. The receiving groove 1273 may be enclosed by the water receiving portion 126, a plurality of partition ribs 1271, and the air outlet portion 120, as shown in FIG. Figure 5 The first heat-insulating member 1274 can be fixed in the receiving groove 1273 by bonding, interference fit or the like.

[0047] The first heat-insulating member 1274 can seal the gap between the water receiving portion 126 and the air outlet portion 120, thereby isolating the cold wind and preventing air leakage from the gap between the two. In addition, the first heat-insulating member 1274 can keep the heat insulated and reduce the heat transfer between the water receiving portion 126 and the air outlet portion 120, thereby reducing the risk of condensation at the air outlet portion 120.

[0048] In some exemplary embodiments, Figure 1 As shown, the water receiving tray 12 further includes an air outlet portion 120 , and the air outlet portion 120 is connected to the water receiving portion 126 .

[0049] In other words, in the embodiment of the present application, the water receiving tray 12 is integrated with the air outlet portion 120 on the basis of the water receiving portion 126, so that it has both the function of receiving condensed water and the function of discharging air, and can better meet the needs of receiving condensed water and discharging air downward of the air conditioner with dual air outlets (lower air outlet and side water outlet).

[0050] In some embodiments, the air outlet 120 and the water receiving portion 126 can be set as an integrated structure, which is conducive to improving the connection strength and matching reliability between the water receiving portion 126 and the air outlet 120, and can save the assembly process between the air outlet 120 and the water receiving portion 126. For example, the air outlet 120 and the water receiving portion 126 can be integrally formed by injection molding, and the above-mentioned partition ribs 1271 can also be integrally formed together, so that the shapes of the water receiving portion 126, the air outlet 120, the air avoidance portion 1270 and other structures can be reasonably set according to needs.

[0051] In other embodiments, the air outlet portion 120 and the water receiving portion 126 may also be provided as a split assembly structure. For example, the water receiving portion 126 and the air outlet portion 120 may be formed separately and then assembled together by fastener connection, clamping, etc. In this case, the air avoidance portion 1270 may also not include the partition rib 1271, and the air avoidance gap may be a complete long strip gap, and the first heat insulating member 1274 may be fixed in the long strip gap.

[0052] Research has found that another reason why condensation is easily generated at the air outlet 120 is that the shapes of the water receiving portion 126 and the air outlet 120 (mainly the longitudinal cross-sectional profile) have a great influence on the wind speed distribution in the air outlet space 125 (e.g. Fig.12 As shown), it is easy to generate a recirculation zone 19 in the air outlet space 125 (as shown Fig. 20 The external hot air easily flows back into the reflow zone 19, contacts the low-temperature inner wall of the air outlet 120, and generates condensation on the low-temperature inner wall of the air outlet 120. The reflow zone 19 easily appears near the inner wall of the air outlet 120 near the water receiving portion 126 (i.e., the first air outlet wall 1251 described below). For this reason, the present application also improves the shape of the water receiving portion 126, the air outlet 120, and the transition curved surface 1275 to reduce the risk of the reflow zone 19 and improve the anti-condensation effect.

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

[0054] In this way, the transition curved surface 1275 forms a part of the wall of the air duct 14, which can play a role in guiding the flow, and is conducive to the smooth transition of the airflow to the air outlet 120 through the water receiving portion 126, thereby achieving the effect of reducing wind resistance and increasing air volume. In addition, such a configuration is conducive to part of the airflow flowing through the transition curved surface 1275 and then flowing along the inner wall (i.e., the first air outlet wall 1251 described below) of the adjacent air outlet 120, thereby reducing the risk of condensation on the inner wall due to the generation of a recirculation zone 19 in the vicinity of the inner wall (i.e., the first air outlet wall 1251 described below).

[0055] In some exemplary embodiments, Fig.10 As shown, the inner side wall of the water receiving portion 126 includes a first side wall 1261. The inner side wall of the air outlet portion 120 includes a first air outlet wall 1251. The cold 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 portion 120 may be substantially in the shape of a quadrangular prism, enclosing a substantially quadrangular prism-shaped air outlet space 125, and the inner side wall of the air outlet portion 120 may 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 end to end in sequence. Figures 5 to 7 As shown. The first air outlet wall 1251 and the third air outlet wall 1253 are relatively spaced apart and have the same or substantially the same length, and the second air outlet wall 1252 and the fourth air outlet wall 1254 are relatively spaced apart and have the same or substantially the same length. In addition, the spacing between the first air outlet wall 1251 and the third air outlet wall 1253 is smaller than the spacing between the second air outlet wall 1252 and the fourth air outlet wall 1254, so the first air outlet wall 1251 and the third air outlet wall 1253 are the inner side walls where the long side of the air outlet space 125 is located, and the second air outlet wall 1252 and the fourth air outlet wall 1254 are the inner side walls where the short side of the air outlet space 125 is located.

[0057] Among the inner side walls of the air outlet portion 120, the first air outlet wall 1251 and the first side wall 1261 are closest to each other, so the cold bridge is mainly established between the first air outlet wall 1251 and the first side wall 1261, and the first air outlet wall 1251 has the lowest temperature and is most likely to produce condensation. Therefore, the cold insulation structure 127 is arranged between the first side wall 1261 and the first air outlet wall 1251, which can effectively reduce the heat transfer between the first side wall 1261 and the first air outlet wall 1251, and effectively reduce the risk of condensation in the air outlet portion 120.

[0058] In some embodiments, along the direction from the first side wall 1261 to the first air outlet wall 1251, the first side wall 1261 extends obliquely upward and toward the direction close to the first air outlet wall 1251, such as Fig.10 In other words, the first side wall 1261 is disposed at an angle, and the upper end of the first side wall 1261 extends at an angle toward the first air outlet wall 1251 .

[0059] In this way, the first side wall 1261 can also play a guiding role, which is beneficial to guide the airflow to the air outlet portion 120 and improve the wind speed distribution in the air outlet space 125, so that the wind speed distribution in the air outlet space 125 tends to be uniform, so as to reduce the size of the recirculation zone 19 generated in the air outlet space 125, and reduce the risk of generating a recirculation zone 19 in the air outlet space 125, thereby helping to further reduce the risk of condensation in the air outlet portion 120.

[0060] In some exemplary embodiments, the bottom wall 1266 of the water receiving trough 1260 is provided with a diversion slope 1267, such as Fig.10 The guide slope 1267 is connected to the first side wall 1261, and is arranged to extend in a direction from the first side wall 1261 to the first air outlet wall 1251, and the guide slope 1267 is arranged to extend in a direction upward and close to the first side wall 1261, and the inclination angle of the guide slope 1267 relative to the horizontal plane is smaller than the inclination angle of the first side wall 1261 relative to the horizontal plane, as shown in FIG. Fig.10 In other words, the guide slope 1267 is inclined, and the upper end of the guide slope 1267 extends obliquely toward the direction close to the first air outlet wall 1251 .

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

[0062] In some exemplary embodiments, Fig.10 and Fig.11 As shown, the first air outlet wall 1251 is configured to smoothly transition from the upper end to the lower end. The middle portion of the first air outlet wall 1251 in the height direction is configured to be an arc-shaped curved surface convex in the direction away from the first side wall 1261. The maximum horizontal spacing 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 spacing between the lower end of the first air outlet wall 1251 and the upper end of the first air outlet wall 1251.

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

[0064] In this way, the first air outlet wall 1251 can also play a guiding role, which is beneficial to guide part of the airflow to flow from the upper end to the lower end of the first air outlet wall 1251 along the first air outlet wall 1251, so as to further reduce the size of the recirculation zone 19 generated in the air outlet space 125, and further reduce the risk of generating a recirculation zone 19 in the air outlet space 125, thereby helping to further reduce the risk of condensation in the air outlet portion 120.

[0065] In some exemplary embodiments, Fig.10 As shown, the upper end of the first side wall 1261 and the upper end of the first air outlet wall 1251 are transitioned by a transition curved surface 1275. The radius R of the transition curved surface 1275 is greater than or equal to 5 mm.

[0066] If the radius of the transition curved surface 1275 is too small, it is difficult to play an effective role in guiding and preventing condensation; if the radius of the transition curved surface 1275 is too large, the size of the water receiving tray 12 will be too large. Therefore, setting the radius of the transition curved surface 1275 within the above range can not only play a good role in guiding and preventing condensation, but also take into account the overall size of the water receiving tray 12, which is conducive to reducing the volume 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 side wall 1261 is less than the height of the other side walls of the water receiving trough 1260. Fig.10 As shown, the vertical distance H1 between the top of the transition curved surface 1275 and the lowest point of the bottom wall 1266 of the water receiving trough 1260 determines the highest water level that the water receiving trough 1260 can accommodate.

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

[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 (for example, 15mm, 20mm, 25mm, 30mm, 35mm, etc.), it can take into account the water collection needs of the air conditioner and the resistance problem of the air duct 14, and better meet the water collection needs and air outlet 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, Fig.10 As shown, the air outlet space 125 has an upper port and a lower port that are relatively spaced apart, and the upper port is located upstream of the lower port along the airflow direction of the air outlet space 125. The width W2 of the upper port is greater than the width W1 of the lower port.

[0073] In some embodiments, the inner side wall of the air outlet portion 120 includes a third air outlet wall 1253 which is spaced apart from the first air outlet wall 1251. 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] In this way, the airflow entering the air outlet space 125 from the upper port can tend to converge in the air outlet space 125 first, so that part of the airflow can flow downward along the first air outlet wall 1251, thereby improving the wind speed distribution. The risk of generating a recirculation zone 19 in the air outlet space 125 is further reduced, which is beneficial to further reduce the risk of condensation in the air outlet portion 120.

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

[0076] If W1 is too large, it is not conducive to the uniform distribution of airflow speed in the air outlet space 125; if W1 is too small, the air volume will be too small. If the difference between W2 and W1 is too large, the air volume will be too small; if the difference between W2 and W1 is too small, the effect of improving the wind speed distribution is not obvious.

[0077] Research has shown that W1 and W2 within the above range can take into account both the effect of improving wind speed distribution and the air outlet requirements, and better meet the anti-condensation and air outlet requirements of the air conditioner.

[0078] In some exemplary embodiments, the air outlet 120 and the water receiving portion 126 enclose a relief space 128 located at the lower side of the cold insulation structure 127, such as Figure 5 The water receiving tray 12 also includes a second heat-insulating member 1281 filled in the avoidance space 128, as shown in FIG. Figure 4 This can further isolate the heat transfer between the water receiving portion 126 and the air outlet portion 120, which is beneficial to further improve the anti-condensation effect.

[0079] In some exemplary embodiments, the outer wall surface of the water receiving portion 126 and the outer wall surface of the air outlet portion 120 are covered with a third heat-insulating member 129, such as Figure 4 and Fig. 9 This can provide a better heat preservation effect on the water connection part 126 and the air outlet part 120, and is also conducive to further improving the anti-condensation effect.

[0080] In some exemplary embodiments, a sealing portion is further provided at the upper end of the air outlet portion 120 , and the sealing portion is disposed along the circumference of 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 discharge air and the air conditioner only needs to discharge air from the side, the sealing part can be sealed and cooperated with surrounding components (such as the wind guide plate, wind guide support 13 and other components described below) to completely close the air outlet space 125, which is beneficial for preventing condensation from being generated by air leakage in the air outlet space 125 and also for preventing howling from being generated by air leakage.

[0082] In some embodiments, 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 which are sequentially arranged 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 a relative interval, and the lengths are equal or substantially equal. The second overlapping edge 122 and the ninth overlapping edge 1241 are arranged at a relative interval, and the lengths are equal or substantially equal. The spacing between the first overlapping edge 121 and the third overlapping edge 123 is greater than the spacing 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 short side of the air outlet portion 120, and the second overlapping edge 122 and the ninth overlapping edge 1241 are arranged along the long side of the air outlet portion 120.

[0083] In some embodiments, Figures 2 to 4 As shown, the first overlap edge 121, the second overlap edge 122 and the third overlap edge 123 are configured to overlap and seal with the first air guide plate 21 described below. The ninth overlap edge 1241 is configured to seal with the air guide support 13 described below, as shown Figure 4 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. Figure 1 Compared with arranging the air outlet 120 in the middle of the water receiving tray 12 in the width direction, the water receiving tray 12 of this solution has a simpler structure and is easier to process and shape.

[0085] The air outlet 120 may be located at the downstream side of the water receiving portion 126. In this way, the distance between the air outlet 120 and the side air outlet of the air conditioner is small, so that the air outlet 120 and the side air outlet share a common air guide plate (such as the first air guide plate 21 described below) to simplify the air guide structure of the air conditioner.

[0086] In some embodiments, Figure 1 As shown, the water receiving tank 1260 includes a water receiving tank body 1268. The air outlet space 125 is located on one side of the width direction of the water receiving tank body 1268, and the length of the air outlet space 125 is less than or equal to the length of the water receiving tank body 1268. This is conducive to improving the safety of the water receiving margin of the water receiving tank 1260.

[0087] In some embodiments, Figure 1 As shown, the length of the air outlet space 125 is less than the length of the water receiving trough body 1268. The water receiving trough 1260 further includes an end trough 1269 connected to the water receiving trough body 1268, and the end trough 1269 is located on one side or both sides of the length direction of the air outlet space 125.

[0088] The volume of the water receiving tank 1260 is larger, which is conducive to improving the safety of the water receiving margin. In addition, the structure of the water receiving tray 12 is more regular, which is convenient for processing and molding, and is also convenient for assembly.

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

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

[0091] like Figures 13 to 21 As shown, the embodiment of the present application further provides an air conditioner, including a shell 1, and the shell 1 includes a water receiving tray 12 of any one of the above embodiments, so it has all the above beneficial effects, which will not be repeated here.

[0092] In some exemplary embodiments, Fig.13 and Fig.17 As shown, the housing 1 further includes a shell 11 and an air guide support 13, the air conditioner further includes an air guide mechanism 4, the air guide support 13 is connected to the shell 11, and the water receiving tray 12 is connected to the shell 11 and the air guide support 13. An air duct 14 is provided in the shell 11.

[0093] like Fig.14 As shown, the air outlet portion 120 and the air guide support 13 enclose a first air outlet 151 that is connected to the air outlet space 125, and the air guide support 13 is provided with a second air outlet 152. 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.

[0094] like Fig.21 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.

[0095] like Fig.21 As shown, the air guide mechanism 4 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 Fig.17 ), 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 Fig.13 ), 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. 20 shown).

[0096] The air conditioner provided in the embodiment of the present application is provided with a first air outlet 151 and a second air outlet 152 with different air outlet directions and a first air guide plate 21 and a second air guide plate 22 matched with the first air outlet 151 and the second air outlet 152, so that the air conditioner can have three air outlet modes, which is convenient for the user to reasonably select the air outlet mode according to the needs, is conducive to meeting the different air outlet needs of the user, and is conducive to improving the user experience.

[0097] Furthermore, the first air outlet 151 and the second air outlet 152 can be controlled to open and close and switch between the three air outlet modes only with the cooperation of the first air guide plate 21 and the second air guide plate 22, without the need for other wind shielding components or wind guiding components (such as a movable volute tongue or other deformable or movable wind shielding mechanisms), thereby simplifying the structure of the air conditioner and reducing production costs.

[0098] 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.

[0099] In some embodiments, the first air outlet 151 may be a downwind air outlet, discharging air downward; the second air outlet 152 may 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 dual air outlet mode. When the user needs rapid cooling or rapid heating, the first air outlet mode can be selected, and the airflow is discharged downward through the first air outlet channel, such as Fig.17 As 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 Fig.14 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. 20 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.

[0100] In the related art, ordinary central air-conditioning duct-type indoor units are usually embedded in the ceiling and installed with one air inlet and one air outlet. They usually adopt the form of bottom air inlet, side air outlet and engineering grille (fixed air outlet direction). However, this form of air supply prevents the hot air from falling to the ground, and the air supply under the indoor unit cannot reach it, resulting in a large air supply blind area and a large temperature difference between near and far. Some products are equipped with electric panels (adjustable air outlet direction) to adjust the air outlet direction, but they have the disadvantages of high cost, difficulty in matching with home decoration, and difficulty in installation, so the actual standard configuration rate is relatively low. Some products adopt the form of bottom air outlet, but there is a problem that the cooling air is easy to blow directly on the human body, and the product acceptance is relatively low.

[0101] The air conditioner provided in the embodiment of the present application is provided with two air outlets with different air outlet directions, which can realize three different air outlet modes. Users can reasonably choose according to their needs. The first air outlet mode can solve the problem that the hot air cannot fall to the ground in the heating mode, the second air outlet mode can solve the problem that the cold air blows directly on the human body in the cooling mode, and the third air outlet mode can solve the problem of large air supply blind area and large temperature difference between near and far, which effectively solves the pain points of existing duct-type indoor units. In addition, the air conditioner can be matched with ordinary engineering grilles, which is more coordinated with the home decoration style and is very popular among users; it can also be matched with electric panels to further improve the user experience.

[0102] In some exemplary embodiments, Fig.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 arranged to be able to close the first air outlet 151 and open the second sub-air outlet 1522 relative to the housing 1 in a first position (such as Fig.13 ), open the first air outlet 151 and the second sub-air outlet 1522 to the second position (as shown in Fig. 20 ), opening the first air outlet 151 and closing the third position of the second sub-air outlet 1522 (as shown in Fig.17 shown).

[0104] The second air guide plate 22 is rotatably connected to the housing 1 and is arranged to be able to close the first sub-air port 1521 in a fourth position (such as Fig.17 ) and the fifth position (as shown) of opening the first sub-air port 1521 Fig.13 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 outlet 151 is opened and the second air outlet 152 is closed, and the air conditioner is in the first air outlet mode. Fig.17 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 outlet 151 is closed and the second air outlet 152 is opened, and the air conditioner is in the second air outlet mode. Fig.13 and Fig.14 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 outlet 151 is opened, the second air outlet 152 is opened, and the air conditioner is in the third air outlet mode. Fig. 20 shown.

[0108] 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.

[0109] 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.

[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 in the horizontal direction. 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 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. In this way, it is convenient to reasonably set 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 according to needs, which is conducive to optimizing the structural layout of the air conditioner without affecting the appearance of the air conditioner.

[0111] The first air outlet is arranged in the horizontal direction, and the second air outlet is arranged in the vertical direction. For example, the first air outlet can be arranged downward, and the second air outlet 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.

[0112] In some exemplary embodiments, 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. Fig.14 As shown, the first rotating part 211 is located between the first air outlet 151 and the second sub-air outlet 1522. The second air guide plate 22 is provided at the end in the width direction or between the two ends thereof with a second rotating part 221 rotatably connected to the housing 1, as shown in FIG. Fig.17 shown.

[0113] In other words, the rotating part 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.

[0114] The position of the rotating portion 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, or between the two ends of the second air guide plate 22 in the width direction.

[0115] In some exemplary embodiments, the air guide support 13 is provided with a first arc groove 132 and a second arc groove 133. Fig.14 and Fig.17 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 .

[0116] 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.

[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 which are sequentially arranged along the circumference of the first air outlet 151. Figures 14 to 16 The air guide support 13 is provided with a fourth overlapping edge 134 arranged 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 in sequence along the circumference of the second air outlet 152, as shown in FIG. Figures 17 to 19 shown.

[0118] 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. Figures 14 to 16 shown.

[0119] 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, an end of the second air guide plate 22 close to the first air guide plate 21 and the eighth overlap edge 138, as shown in FIG. Figures 17 to 19 shown.

[0120] Based on the second air guide plate 22 being located at the fourth position, the circumferential end of the second air guide plate 22 overlaps and seals with the seventh overlap edge 137, the sixth overlap edge 136, an end of the first air guide plate 21 close to the second air guide plate 22, and the eighth overlap edge 138. Figures 17 to 19 shown.

[0121] 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.

[0122] 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.

[0123] 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.

[0124] In some embodiments, the water receiving tray 12 is further provided with a ninth overlapping edge 1241 which is spaced apart from the second overlapping edge 122. Figure 4 The ninth overlap edge 1241 is sealed with one end of the air guide support 13 close to the water receiving tray 12 .

[0125] The second overlapping edge 122 may be provided on the first heat-insulating member 1274, that is, a part of the first heat-insulating 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 may overlap and seal with the first air guide plate 21 when the air conditioner is in the second air outlet mode, and the end of the first air guide plate 21 that is not overlapped and sealed with the air outlet portion 120 is sealed with the air guide support 13, thereby achieving complete sealing of the first air outlet 151.

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

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

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

[0129] 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.

[0130] 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.

[0131] In some exemplary embodiments, Fig.17 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 output in the second air outlet mode and the third air outlet mode.

[0132] In some exemplary embodiments, when the air conditioner is in the third air outlet mode, at the same air volume, the air volume at the first air outlet 151 is significantly reduced compared to the first air outlet mode, which will lead to uneven wind speed distribution, so that the area in the first air outlet 151 away from the second air outlet 152 generates a recirculation zone 19 (such as Fig. 20 The hot and cold air will 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 dripping, such as condensation forming on the inner wall surface of the recirculation zone 19, causing dripping.

[0133] Therefore, when the current working condition is in the set condensation working condition (for example, the indoor temperature is greater than or equal to the first set temperature, the indoor humidity is greater than or equal to the set humidity, and the temperature of the indoor heat exchanger 3 of the air conditioner is 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 the third air outlet mode has been running for a period of time (the third set duration), switch to the first air outlet mode for a period of time (the first set duration), and then 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 (the second set duration), it will switch to the first air outlet mode again. This cycle repeats, and on the basis of ensuring the full-area air outlet needs, condensation at the first air outlet 151 is avoided as much as possible to cause dripping.

[0134] 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.
