The end of the water baffle closer to the side wall is higher than the other end. The drain hole is always located inside the air outlet.

[0033] After condensation forms on the air guide plate, the condensate flows downwards along it. Upon reaching the lower end of the air guide plate, the condensate flows along the inclined baffle towards the drain outlet and then into the water collection chamber. The inclined baffle and drain outlet design ensure that the condensate on the air guide plate flows from the drain outlet into the water collection chamber, preventing it from being blown into the room by the heat exchange airflow or flowing from the lower end of the air guide plate to the outside of the indoor unit, thus improving the user experience.

[0034] Furthermore, since the projection of the second mounting base on the bottom wall completely covers the projection of the first mounting base on the bottom wall, when the condensate flows downward from the air guide plate, it flows directly from the second mounting base into the water receiving cavity, preventing the condensate from entering the first mounting base and damaging the lower rotating shaft and the first mounting base, thus extending the service life of the first mounting base and the air guide plate, and consequently extending the service life of the indoor unit of the air conditioner.

[0047] Figure 1 This is a schematic structural diagram of an indoor unit of an air conditioner according to an embodiment of the present invention, as shown below. Figure 1 As shown, and with reference Figures 2 to 6This utility model provides an indoor unit 100 for an air conditioner, including a housing 10 and an air guide plate 410. The housing 10 has an air outlet 20 extending vertically. A water receiving cavity 310 is provided on the inner side of the lower end of the air outlet 20. A first mounting seat 330 protruding upwards from the bottom wall of the water receiving cavity 310 is provided on the bottom wall of the water receiving cavity 310. The air guide plate 410 is rotatably disposed at the air outlet 20 about a vertical axis. A second mounting seat 420, a water baffle 430, and a lower rotating shaft 440 disposed on the lower end of the air guide plate 410 are provided. The lower rotating shaft 440 is mounted on the first mounting seat 330. The second mounting seat 420 is located above the first mounting seat 330, and the projection of the second mounting seat 420 on the bottom wall completely covers the projection of the upper end of the first mounting seat 330 on the bottom wall. 。 A baffle plate 430 is connected to one side wall of the air guide plate 410, and a drain hole 450 is provided between the baffle plate 430 and the peripheral wall of the second mounting base 420. During the rotation of the air guide plate 410, the drain hole 450 is always located on the upper side of the water receiving cavity 310 and inside the upper opening of the water receiving cavity 310. The end of the baffle plate 430 away from the second mounting base 420 is higher than the other end of the baffle plate 430.

[0048] In this embodiment, the indoor unit 100 of the air conditioner includes a housing 10 and an air guide plate 410. An air outlet 20 is provided on the housing 10. A water receiving cavity 310 is provided on the lower inner side of the air outlet 20, and a first mounting base 330 is provided on the bottom wall of the water receiving cavity 310. A second mounting base 420 and a lower rotating shaft 440 are provided on the lower end of the air guide plate 410. The lower end of the lower rotating shaft 440 is mounted on the first mounting base 330, so that the air guide plate 410 is rotatably disposed at the air outlet 20. The projection of the second mounting base 420 on the bottom wall completely covers the projection of the first mounting base 330 on the bottom wall. A baffle plate 430 is also provided at the lower end of the air guide plate 410. One end of the baffle plate 430 is connected to the side wall of the air guide plate 410, and a drain hole 450 is provided between the other end and the peripheral wall of the second mounting base 420. The end of the baffle plate 430 near the side wall is higher than the other end. The drain hole 450 is always located inside the air outlet 20.

[0049] After condensation occurs on the air guide plate 410, the condensate flows downwards along the air guide plate 410. When the condensate reaches the lower end of the air guide plate 410, it flows along the inclined baffle plate 430 to the drain hole 450, and then from the drain hole 450 into the water receiving chamber 310. The inclined baffle plate and the drain hole 450 ensure that the condensate on the air guide plate 410 flows from the drain hole 450 into the water receiving chamber 310, preventing the condensate from being blown into the room by the heat exchange airflow, or from flowing from the lower end of the air guide plate 410 to the outside of the indoor unit 100 of the air conditioner, thus improving the user experience.

[0050] Furthermore, since the projection of the second mounting base 420 on the bottom wall completely covers the projection of the first mounting base 330 on the bottom wall, when the condensate flows downward from the air guide plate 410, it flows directly from the second mounting base 420 into the water receiving cavity 310, preventing the condensate from entering the first mounting base 330 and damaging the lower rotating shaft 440 and the first mounting base 330, thus extending the service life of the first mounting base 330 and the air guide plate 410, and consequently extending the service life of the indoor unit 100 of the air conditioner.

[0051] In some embodiments of this utility model, such as Figure 2 As shown, the air guide plate 410 has a first part 411 located outside the air outlet 20 and a second part 412 located inside the air outlet 20 after the air outlet 20 is opened. The water baffle 430 is disposed on one side of the second mounting base 420, and the end of the water baffle 430 away from the second mounting base 420 is located on the first part 411 of the air guide plate 410.

[0052] In this embodiment, after the air outlet 20 is opened by the air guide plate 410, the first part 411 is located on the outside of the air outlet 20, and the second part 412 is located on the inside of the air outlet 20. The baffle plate 430 is connected to the side wall on one side of the first part 411. When the air outlet 20 is opened by the air guide plate 410, the condensate on the first part 411 flows downward along the baffle plate 430 and flows into the water receiving chamber 310 from the drain hole 450. The condensate on the second part 412 flows downward along the air guide plate 410 and directly enters the water receiving chamber 310. By only setting the baffle plate 430 on one side of the first part 411 of the air guide plate 410, the amount of processing material used for the air guide plate 410 is reduced, the processing difficulty of the air guide plate 410 is reduced, the processing efficiency of the air guide plate 410 is improved, and thus the processing cost is saved.

[0053] In some embodiments of this utility model, such as Figure 3 and Figure 4 As shown, the housing 10 has an air outlet duct 50 connected to the air outlet 20. A water receiving cavity 310 is disposed on the bottom wall of the air outlet duct 50. A water outlet hole 320 is provided on the bottom wall of the water receiving cavity 310.

[0054] In this embodiment, an air outlet duct 50 is provided inside the housing 10, and a water collection chamber 310 is disposed on the bottom wall of the air outlet duct 50. The heat exchange airflow is blown out along the air outlet duct 50 and into the room through the air outlet 20. A water outlet hole 320 is provided on the bottom wall of the water collection chamber 310. The condensate generated on the air guide plate 410 enters the water collection chamber 310 and is discharged from the indoor unit 100 of the air conditioner through the air outlet hole, preventing the condensate from staying in the water collection chamber 310 for a long time and breeding bacteria, thereby avoiding the heat exchange airflow blowing bacteria into the room and affecting the user's health, and further improving the user experience.

[0055] In some embodiments of this utility model, such as Figure 3 As shown in the figure, the indoor unit 100 of the air conditioner also includes an air outlet grille 60 and a plurality of slots 70. The air outlet grille 60 is disposed within the air outlet duct 50. The air outlet grille 60 includes a plurality of vertical partitions 610. The plurality of slots 70 are disposed on the bottom wall of the water receiving cavity 310. Each slot 70 includes a first protrusion 710 and a second protrusion 720, the first protrusion 710 and the second protrusion 720 defining an upward-opening slot 730, the lower end of each vertical partition 610 being inserted into a slot 730. At least one vertical edge of the first protrusion 710 and a corresponding vertical edge of the second protrusion 720 are spaced apart to provide a water flow notch 740 in the slot 730.

[0056] In this embodiment, an air outlet grille 60 is provided inside the air outlet duct 50, and the air outlet grille 60 includes multiple vertical partitions 610. Multiple grooves 70 are provided on the bottom wall of the water receiving cavity 310. Each groove 70 includes a first protrusion 710 and a second protrusion 720, which define a slot 730. The slot 730 has a water flow notch 740. The lower end of the vertical partition 610 is inserted into the slot 730 to fix the air outlet grille 60. Condensate formed on the air outlet grille 60 flows downward along the vertical partition 610 and enters the slot 730 at the lower end of the vertical partition 610. Because the slot 730 has a water flow notch 740, the condensate flows from the water flow notch 740 into the water receiving cavity 310. The water flow notch 740 allows condensate on the vertical partition 610 to flow into the water receiving cavity 310, preventing condensate from accumulating in the slot 730. This prevents bacteria from growing inside the indoor unit 100 of the air conditioner, avoids the heat exchange airflow blowing bacteria into the room and affecting the user's health, and further improves the user experience.

[0057] In some embodiments of this utility model, such as Figure 3 and Figure 5 As shown, a fixing plate 620 is provided at the upper end of the air outlet grille 60. The fixing plate 620 is provided with mounting holes 630 extending in the front-rear direction. The mounting holes 630 are configured to allow screws to be inserted from the front.

[0058] In this embodiment, a fixing plate 620 is provided above the air outlet grille 60, and the fixing plate 620 is provided with mounting holes 630 extending in the front-to-back direction. When installing the air outlet grille 60, first insert the lower end of the vertical partition plate 610 into the slot 730, and then insert the screw into the mounting hole 630 from the front and screw it into the housing 10. The fixing structure of the air outlet grille 60 is simple, and the fixing method is simple and convenient, which facilitates the installation and removal of the air outlet grille 60.

[0059] In some embodiments of this utility model, such as Figure 3 and Figure 4As shown, the air outlet grille 60 also includes a bottom partition 640, which extends laterally and is disposed at the lower end of the vertical partition 610. The bottom partition 640 is located within the water receiving cavity 310 and is located on the lower side of the bottom wall of the air outlet duct 50.

[0060] In this embodiment, a bottom partition 640 is provided below the vertical partition 610. The bottom partition 640 extends horizontally and is located within the water collection chamber 310 and below the bottom wall of the air outlet duct 50. When condensation forms on the bottom partition 640, even if the condensation is blown off by the heat exchange airflow, it will still enter the water collection chamber 310. The bottom partition 640's location below the bottom wall of the air outlet duct 50 prevents condensation on it from being blown outside the air outlet 20, thus improving the user experience.

[0061] In some embodiments of this utility model, the distance between the bottom partition 640 and the bottom wall of the air outlet duct 50 is within 10mm. The distance between the bottom partition 640 and the rear wall of the water receiving cavity 310 is within 10mm.

[0062] In this embodiment, the distance between the bottom partition 640 and the bottom wall of the air outlet duct 50 is within 10mm. For example, the distance between the bottom partition 640 and the bottom wall of the air outlet duct 50 is 2mm, 4mm, 6mm, 8mm, or 10mm. The bottom partition 640 can guide the heat exchange airflow forward, reduce heat exchange airflow loss, and improve the air outlet efficiency of the air outlet duct 50. The distance between the bottom partition 640 and the rear wall of the water receiving cavity 310 is within 10mm. For example, the distance between the bottom partition 640 and the rear wall of the water receiving cavity 310 is 2mm, 4mm, 6mm, 8mm, or 10mm. The bottom partition 640 is located at the rear of the water receiving cavity 310. Even if water on the bottom partition 640 is blown off, because the bottom partition 640 is close to the rear wall of the water receiving cavity 310, the condensate drips into the water receiving cavity 310, preventing a large amount of water from being blown out of the air outlet 20, thus improving the user experience.

[0063] In some embodiments of this utility model, such as Figure 4 As shown, the bottom wall of the air outlet duct 50 includes an air guide area 80 connected to the upper end of the rear wall of the water receiving cavity 310. The rear end of the air guide area 80 is lower than the upper end of the rear wall of the water receiving cavity 310, and the air guide area 80 is an inclined surface.

[0064] In this embodiment, the bottom wall of the air outlet duct 50 includes a guide region 80, the front end of which is connected to the upper end of the rear wall of the water receiving cavity 310. The rear end of the guide region 80 is lower than the front end, meaning the guide region 80 is a sloping surface that slopes downwards from front to back. When the heat exchange airflow is blown out from the air outlet duct 50, the lower guide region 80 guides the airflow forward and upward, preventing the heat exchange airflow from flowing into the lower water receiving cavity 310. This avoids the heat exchange airflow forming eddies in the water receiving cavity 310 or causing significant resistance due to contact between the heat exchange airflow and the front wall of the water receiving cavity 310, thereby improving the air outlet efficiency of the air outlet duct 50, ensuring smooth flow of the heat exchange airflow, and thus improving the air outlet effect of the indoor unit 100 of the air conditioner.

[0065] In some embodiments of this utility model, such as Figure 2 and Figure 6 As shown, the air guide plate 410 includes a guide plate 413 and a reinforcing member 414, with the reinforcing member 414 disposed on the inner side of the guide plate 413. The reinforcing member 414 has multiple through holes 415 extending along the length of the guide plate 413 and penetrating the reinforcing member 414. A water baffle 430 is connected to the guide plate 413 and is located below the reinforcing member 414, extending beyond the reinforcing member 414 in a direction away from the guide plate 413. The higher end of the water baffle 430 is positioned near the edge of the guide plate 413.

[0066] In this embodiment, the air guide plate 410 includes a guide plate 413 and a reinforcing member 414 located inside the guide plate 413. The reinforcing member 414 has a through hole 415 extending vertically. A baffle plate 430 is located below the reinforcing member 414, and the direction of the baffle plate 430 away from the guide plate 413 extends beyond the reinforcing member 414. The reinforcing member 414 is used to strengthen the structural strength of the guide plate 413 and improve its mechanical strength. Furthermore, the reinforcing member 414 also provides heat insulation. When the heat exchange airflow passes through the reinforcing member 414, the presence of air within the through hole 415 reduces the heat conduction efficiency of the reinforcing member 414, thus minimizing heat loss and preventing any impact on the airflow performance of the indoor unit 100 of the air conditioner. Additionally, the through hole 415 within the reinforcing member 414 reduces the temperature change on the outer surface of the guide plate 413, mitigating the formation of condensate on its outer surface.

[0067] Furthermore, during air conditioner operation, condensation may form on the inner wall of the reinforcing member 414 as the heat exchange airflow passes through it. Due to the through-hole 415, the condensation collects and flows out along the inner wall of the reinforcing member 414, then along the baffle plate 430, and enters the water receiving chamber 310 through the drain hole 450. Because the baffle plate 430 extends away from the guide plate 413 beyond the reinforcing member 414, it prevents condensation dripping from the through-hole 415 or inner surface of the reinforcing member 414 from falling onto the outside of the indoor unit 100 of the air conditioner, thus improving the user experience.

[0068] In some embodiments of this utility model, such as Figure 2 As shown, the second mounting base 420 is disposed at the lower end of the inner surface of the guide plate 413. The lower end of the baffle plate 430 is connected to the second mounting base 420 through a rib plate 460, which is spaced apart from the inner surface of the guide plate 413 to form a drain hole 450.

[0069] In this embodiment, the second mounting base 420 is located at the lower end of the inner surface of the guide plate 413, the lower end of the baffle plate 430 is connected to the rib plate 460, and the other end of the rib plate 460 is connected to the second mounting base 420. There is a gap between the rib plate 460 and the inner surface of the guide plate 413. A drainage hole 450 is defined between the rib plate 460, the guide plate 413, the baffle plate 430, and the second base. The rib plate 460 also enhances the structural strength of the baffle plate 430 and the second mounting base 420, reducing the risk of damage to the baffle plate 430.

[0070] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
