[0032] The air conditioner 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0033] like Figures 1 to 5 As shown, the air conditioner 100 according to an embodiment of the present utility model includes: a housing assembly 1 and a heat exchange and air supply assembly 2. An air inlet 11 and an air outlet 12 are formed on the housing assembly 1. A water receiving trough 13 and an air outlet channel 14 are formed inside the housing assembly 1. The side wall of the air outlet channel 14 includes a first side wall 141. At least a portion of the bottom wall of the water receiving trough 13 constitutes the first side wall 141. A rib 15 is provided on the side of the first side wall 141 facing the air outlet channel 14. The heat exchange and air supply assembly 2 is disposed inside the housing assembly 1. It is understood that during the operation of the air conditioner 100, the heat exchange air supply component 2 can drive air to enter the casing component 1 through the air inlet 11 and discharge it through the air outlet 12 after heat exchange and adjustment. When the heat exchanger 21 of the heat exchange air supply component 2 comes into contact with the air entering through the air inlet 11, water droplets are easily condensed on the heat exchanger 21 due to the temperature difference. The water receiving tank 13 can catch the condensation generated during the heat exchange process of the heat exchange air supply component 2 to prevent the condensate from flowing out and polluting the internal environment of the casing component 1.

[0034] In related technologies, when the air conditioner is in cooling mode, the temperature of the condensation generated on the heat exchange air supply component is relatively low. When the condensation enters the water collection tank, the temperature of the bottom wall of the water collection tank also decreases. When the air outlet draws in air from the outside environment at a relatively high speed, generating return air, the temperature of the outside environment is relatively high. When the high-temperature return airflow comes into contact with the bottom wall of the water collection tank, water droplets easily condense on the side of the bottom wall of the water collection tank facing the air outlet channel.

[0035] Therefore, by providing a rib 15 on the side of the first sidewall 141 facing the air outlet duct 14, the thickness of the bottom wall of the water receiving tank 13 can be increased, thereby increasing the distance between the condensate in the water receiving tank 13 and the airflow in the air outlet duct 14. This increases the distance between the lower-temperature condensate in the water receiving tank 13 and the airflow in the air outlet duct 14, thus reducing the impact of the condensate in the water receiving tank 13 on the temperature of the inner wall surface of the area corresponding to the bottom wall of the air outlet duct 14 and the bottom wall of the water receiving tank 13. In other words, the rib 15 can provide good insulation for the bottom wall of the water receiving tank 13, thereby preventing the temperature of the corresponding area of ​​the inner wall surface of the air outlet duct 14 and the bottom wall of the water receiving tank 13 from being too low, and thus reducing the condensation generated on the inner wall surface of the air outlet duct 14 during return air.

[0036] According to the embodiment of the present utility model, the air conditioner 100 can increase the thickness of the bottom wall of the water receiving tank 13 by providing a rib 15 on the side of the first side wall 141 facing the air outlet duct 14. This allows the rib 15 to provide good heat preservation for the bottom wall of the water receiving tank 13, thereby preventing the temperature of the corresponding area between the inner wall of the air outlet duct 14 and the bottom wall of the water receiving tank 13 from being too low. This, in turn, reduces the condensation generated on the inner wall of the air outlet duct 14 during return air.

[0037] According to some embodiments of this utility model, the raised rib 15 is a strip extending along the length direction of the air outlet 12. This effectively increases the coverage area of ​​the raised rib 15 along the length direction of the air outlet 12, thereby more uniformly reinforcing the thickness of the bottom wall of the water receiving tank 13 along the length direction of the air outlet 12, thus improving the heat insulation effect of the raised rib 15 on the bottom wall of the water receiving tank 13. In a specific example, the length of the raised rib 15 along the length direction of the air outlet 12 can be set to be consistent with the length of the air outlet 12 to ensure the heat insulation effect of the raised rib 15.

[0038] According to some embodiments of this utility model, multiple ribs 15 are provided. It is understood that the more ribs 15 there are, the larger the coverage area on the side wall 141 facing the air outlet channel 14, and the more locations where the bottom wall thickness of the water receiving tank 13 can be increased. Therefore, by providing multiple ribs 15, the heat insulation effect of the bottom wall of the water receiving tank 13 can be improved, thereby further reducing the impact of condensate in the water receiving tank 13 on the temperature of the inner wall surface of the air outlet channel 14, and preventing condensation from forming on the inner wall surface of the air outlet channel 14.

[0039] According to some embodiments of this utility model, a plurality of raised ribs 15 are arranged at intervals along a first direction (e1 as shown in the figure), the first direction being perpendicular to the length direction of the air outlet 12. Specifically, the plurality of raised ribs 15 are arranged at intervals along the air outlet direction of the air outlet channel 14. By arranging the plurality of raised ribs 15 at intervals, the impact on the overall thickness of the first sidewall 141 can be reduced, thereby avoiding injection molding defects caused by excessive local thickness of the first sidewall 141, and thus improving the production yield of the housing assembly 1.

[0040] In other embodiments, the ribs 15 may also extend along a first direction, and multiple ribs 15 may be arranged at intervals along the length of the air outlet 12. In other words, the extension direction and arrangement direction of the ribs 15 can be flexibly adjusted according to requirements.

[0041] It should be noted that in some embodiments, the multiple ribs 15 can be evenly spaced, that is, the interval between any two adjacent ribs 15 is the same, in order to reduce the design and molding difficulty. In other embodiments, the multiple ribs 15 can also be non-uniformly spaced, that is, the interval between any two adjacent ribs 15 can be different. No specific restrictions are made here.

[0042] According to some embodiments of this utility model, the area where the plurality of protruding ribs 15 are disposed on the first sidewall 141 is an arrangement area. Along the first direction, in the direction from the center of the arrangement area towards the upstream and downstream sides, the height of the plurality of protruding ribs 15 decreases. Here, the height of the protruding rib 15 refers to the height of the protruding rib 15 protruding from the sidewall 141 towards the air outlet channel 14. That is, along the first direction, the height of the portion of the plurality of protruding ribs 15 located in the middle position is higher than the height of the portions of the plurality of protruding ribs 15 located on opposite sides. Therefore, along the first direction, the plurality of protruding ribs 15 can smoothly transition with the inner wall surface of the air outlet channel 14 located on the upstream and downstream sides of the arrangement area, which can reduce the resistance of the plurality of protruding ribs 15 to the airflow in the air outlet channel 14. Furthermore, the multiple ribs 15 located on the upstream side can effectively compress the air duct, thereby extending the length of the acceleration section within the air outlet duct 14 and reducing the airflow resistance on the inner wall of the air outlet duct 14 located downstream of the ribs 15. This accelerates the speed at which the airflow exits the air outlet 14 and reaches the air outlet 12, preventing the airflow from lingering and circulating near the air outlet 12. Consequently, backflow is avoided, thus preventing condensation from forming on the inner wall of the air outlet duct 14 due to backflow.

[0043] According to some embodiments of this utility model, the side of the rib 15 facing away from the first sidewall 141 is called the first sidewall 151, and multiple first sidewalls 151 are located on the same curved surface. Therefore, the airflow passing through the rib 15 can flow along the curved surface where multiple first sidewalls 151 are located, which can reduce the resistance of multiple ribs 15 to the airflow, thereby reducing air volume loss and increasing the air volume of the air conditioner 100.

[0044] According to some embodiments of this utility model, the sidewall of the air outlet duct 14 further includes a second sidewall 142 located downstream of the first sidewall 141. The second sidewall 142 has a concave arc surface facing the side of the air outlet duct 14. The second sidewall 142 is connected to the first sidewall 141, and some ribs 15 are located on the first sidewall 141 and some ribs 15 are located on the second sidewall 142. That is, multiple ribs 15 are distributed at the connection position of the first sidewall 141 and the second sidewall 142, and both the first sidewall 141 and the second sidewall 142 are provided with ribs 15. Since the second sidewall 142 is located downstream of the first sidewall 141, when return air is generated at the air outlet 12, the return airflow flows from the second sidewall 142 toward the first sidewall 141. Therefore, by providing a raised rib 15 on the side of the second sidewall 142 facing the air outlet 14, the thickness at the connection point between the second sidewall 142 and the first sidewall 141 can be increased, thereby reducing the influence of condensate in the water tank 13 on the temperature at the connection point between the second sidewall 142 and the first sidewall 141, so as to avoid condensation at the location of the second sidewall 142 and the first sidewall 141.

[0045] In a specific example, the housing assembly 1 includes an air guide plate 19, which is rotatably disposed at the air outlet 12 to open or close the air outlet 12. The side of the first sidewall 141 facing the air outlet channel 14 is the second sidewall, and the side of the second sidewall 142 facing the air outlet channel 14 is the third sidewall. The second sidewall is flat, and the third sidewall is a concave arc surface to prevent the air guide plate 19 from rotating at the air outlet 12. Specifically, multiple ribs 15 can effectively extend the length of the second sidewall along the airflow direction, thereby allowing the airflow flowing through the second sidewall to gain more acceleration, so that the airflow can be directly blown out through the air outlet 12. In addition, multiple ribs 15 can increase the transition slope between the second and third sideswalls, thereby reducing the resistance of the third sidewall to the airflow flowing through the second sidewall, so that the airflow can be discharged through the air outlet 12 more quickly. It should be noted that the side of the second sidewall 142 facing the air outlet 14 can also be a plane. There are no specific restrictions on the shape of the side of the second sidewall facing the air outlet 14.

[0046] According to some embodiments of this utility model, a water-blocking groove 16 extending along the length direction of the air outlet 12 is defined between any two adjacent ribs 15 along the first direction. Therefore, by providing the water-blocking groove 16, when condensation occurs in the area of ​​the ribs 15 and the first sidewall 141 located upstream of the ribs 15, water droplets are retained in the water-blocking groove 16 under tension, thereby preventing the condensed water droplets from being discharged with the airflow. In a specific example, multiple ribs 15 together form a wave shape, and the curved surface can better increase the tension between the water droplets and the ribs 15, thereby improving the effect of multiple water-blocking grooves 16 in blocking water droplets.

[0047] According to some embodiments of this utility model, the cross-section of the rib 15 is hemispherical. That is, the side of the rib 15 facing away from the first sidewall 141 is semi-circular. This can effectively reduce the resistance of the rib 15 to the airflow and avoid sharp structures in the air outlet channel 14 to prevent scratching the user.

[0048] According to some embodiments of this utility model, the height of the rib 15 protruding from the first sidewall 141 ranges from 0.3 to 2 mm. The higher the rib 15 protrudes from the first sidewall 141, the better its insulation effect, but the greater its resistance to airflow within the air outlet channel 14. Conversely, the lower the rib 15 protrudes from the first sidewall 141, the worse its insulation effect, but the smaller its resistance to airflow within the air outlet channel 14. Therefore, by controlling the height of the rib 15 protruding from the first sidewall 141 within the range of 0.3 mm to 2 mm, the insulation effect of the rib 15 on the first sidewall 141 can be maintained to avoid condensation while reducing the resistance to airflow within the air outlet channel 14. The height of the rib 15 protruding from the first sidewall 141 can be 0.3mm, 0.5mm, 0.7mm, 1mm, 1.2mm, 1.5mm, 1.8mm, 2mm, etc.

[0049] According to some embodiments of this utility model, the cross-section of the rib 15 is hemispherical, and the height of the rib 15 protruding from the first sidewall 141 ranges from 0.3 to 2 mm. Therefore, while ensuring the heat insulation effect of the rib 15 on the first sidewall 141 to avoid condensation, the resistance to airflow within the air outlet duct 14 is reduced.

[0050] According to some embodiments of this utility model, the air conditioner 100 is wall-mounted, with the air inlet 11 located at the top of the housing assembly 1 and the air outlet 12 located at the bottom front side of the housing assembly 1. The housing assembly 1 includes a chassis 17, and both the air outlet duct 14 and the water collection tank 13 are formed on the chassis 17. The first side wall 141 is part of the top wall of the air outlet duct 14. Thus, the rib 15 can effectively thicken the portion of the top wall of the air outlet duct 14 located below the water collection tank 13, thereby preventing condensation from forming on the top wall of the air outlet duct 14. In a specific example, the housing assembly 1 also includes a face frame 18 and an air guide plate 19, both of which are mounted on the chassis 17. An air inlet 11 is formed on the top of the face frame 18, and an air outlet 12 is formed on the bottom of the front side of the chassis 17. The length direction of the air outlet 12 is the left-right direction. The air guide plate 19 is rotatably mounted at the air outlet 12. The heat exchange and air supply assembly 2 includes a heat exchanger 21 and a fan component 22. The heat exchanger 21 is located upstream of the fan component 22, and the rotation axis of the fan component 22 extends in the left-right direction.

[0051] According to some embodiments of this utility model, the protruding rib 15 and the first sidewall 141 are integrally formed. Therefore, the integrally formed structure not only ensures the structural and performance stability of the protruding rib 15 and the first sidewall 141, but also facilitates molding and simplifies manufacturing. Furthermore, it eliminates the need for assembly parts and connection processes used to connect the protruding rib 15 and the first sidewall 141, resulting in lower production costs and significantly improved assembly efficiency. This ensures reliable connection between the protruding rib 15 and the first sidewall 141. Moreover, the integrally formed structure has higher overall strength and stability, and a longer service life.

[0052] According to some embodiments of this utility model, the air conditioner 100 is a wall-mounted type. The housing assembly 1 includes a chassis 17, an air outlet duct 14, and a water collection tank 13, all formed on the chassis 17. The first side wall 141 is the top wall of the air outlet duct 14, and the protruding rib 15 is integrally formed with the first side wall 141. This effectively prevents condensation from forming on the top wall of the air outlet duct 14, while also reducing the production cost of the housing assembly 1 and improving its production efficiency.
