As shown in Figures 1 to 9, an embodiment of the present application provides an air-conditioning indoor unit 1, which includes a shell 10; the shell 10 includes a bottom shell member 110 constituting the rear side and the lower side of the shell 10; an air outlet 113 is provided on the bottom shell member 110 located at the bottom front side of the shell 10, and a turbine fan structure 20 is installed in the middle inside the shell 10, and the outlet 201 of the turbine fan structure 20 is opened downward, and the outlet 201 of the turbine fan structure 20 is connected to the lower air outlet 113 through an air outlet duct 30, and the air outlet duct 30 is composed of any one or a combination of the volute 203 of the turbine fan structure 20, the volute tongue member 120, the shell 10 itself and/or the components added to the shell 10, so that the outlet air generated by the turbine fan structure 20 flows through the air outlet duct 30 and flows out from the air outlet 113.

In the embodiment of the present application, a water collecting tray 1101 is also installed at the bottom on the front side of the shell 10. The water collecting tray 1101 is a groove structure integrated on the lower side plate 112 of the bottom shell 110, and the water collecting tray 1101 is located below the inside of the shell 10 near the front side; the upper side of the water collecting tray 1101 is open so that the condensed water generated in the shell 10 can be gathered downward along the inner wall of the shell 10 and flow into the water collecting tray 1101, thereby achieving the effect of collecting the condensed water inside the shell 10.

In the embodiment of the present application, the water collecting tray 1101 is also connected to a drain outlet 1102 that is conductive to the outside. The drain outlet 1102 is generally connected to the bottom of the water collecting tray 1101, so that all condensed water collected in the water collecting tray 1101 can be discharged from the drain outlet 1102.

The joint is connected to an external drain pipe, so that the condensed water flow discharged from the drain outlet 1102 can flow smoothly into the drain pipe under the action of gravity and then be discharged to the outside.

In the embodiment of the present application, a water retaining member 12 is further provided inside the shell 10, and the water retaining member 12 is located on one side of the water collecting pan 1101. The corresponding side wall of the water collecting pan 1101 and the water retaining member 12 arranged on the outside together form an overflow channel 11.

Of course, in the embodiment of the present application, the turbine component 120 is used as an example to discuss the water retaining component 12, but the water retaining component 12 can also be composed of other components, which will not be discussed separately in the present embodiment, but the protection scope of the present application covers the implementation of the above-mentioned other components as the water retaining component 12. Optionally, the outlet 201 of the turbine fan structure 20 is connected to the air outlet 113 through the air outlet duct 30, and the lower end of the overflow channel 11 is connected to the air outlet duct 30 through the overflow drain outlet 1204 opened downward on the vortex tongue component 120, so that the overflow water flowing out of the lower end of the overflow channel 11 flows through the air outlet duct 30 to the air outlet 113, so that the overflow water flows through the air outlet airflow of the air duct and flows to the air outlet 113, and is smoothly discharged from the housing 10 of the air conditioner indoor unit, thereby effectively preventing the overflow water from remaining in the housing 10.

In the embodiment of the present application, a turbine fan structure 20 is arranged inside the shell 10, and the water retaining member 12 is a vortex tongue member 120 arranged on the outer side of the outlet 201 of the turbine fan structure 20; the vortex tongue member 120 is an arc-shaped plate extending along the same arc and arranged on the front side of the turbine fan 202 of the turbine fan structure 20, spaced and close to the front side of the lower half of the turbine fan 202, and the arc-shaped plate constitutes a water guide portion 121, and the upper side of the water guide portion 121 constituted by the arc-shaped plate is connected to the rear of the volute 203 and the water collecting tray 1101.

That is, the overflow channel 11 is composed of the first water channel 1109 , the second water channel 1205 , and the overflow drain port 1204 which are sequentially connected, so that the water collecting tray 1101 is connected to the air outlet 113 .

In the embodiment of the present application, the upper end of the second water channel 1205 is connected to the overflow port 1103 correspondingly opened on the rear side wall 1104 of the water collecting tray 1101; the overflow port 1103 is arranged higher than the drain port 1102 to ensure that all the condensed water collected in the water collecting tray 1101 is preferentially discharged from the drain port 1102. At the same time, in order to guide the smoothness of the overflow condensed water flowing into the second water channel 1205 through the overflow port 1103, a first water channel 1109 can be arranged at the overflow port 1103 to guide the condensed water in the water collecting tray 1101 that reaches the water level of the overflow port 1103 to overflow into the second water channel 1205.

The above-mentioned first water channel 1109 includes an overflow port 1103 arranged on the rear side wall 1104 of the water collecting tray 1101, and the left and right sides of the overflow port 1103 are respectively provided with a first overflow water retaining rib 1107 and a second overflow water retaining rib 1108 protruding toward the outside of the water collecting tray 1101, and the outward horizontal protruding parts of the first overflow water retaining rib 1107 and the second overflow water retaining rib 1108 are correspondingly inserted into the second water channel 1205, and the outer side wall of the overflow water retaining rib on the corresponding side is relatively abutted against the inner side wall of the water retaining rib, so that a reliable water passage is formed at the joint of the first water channel 1109 and the second water channel 1205, effectively preventing the overflow water flow from leaking from the joint of the two water channels. At the same time, in order to guide the water to flow into the second water channel 1205 through the overflow port 1103, a water guide rib 1106 protruding and extending toward the inside of the second water channel 1205 can be provided at the lower side of the overflow port 1103, and the left and right sides of the water guide rib 1106 are respectively connected to the lower sides of the first overflow water retaining rib 1107 and the second overflow water retaining rib 1108, and the rear ends of the water guide rib 1106 and the first overflow water retaining rib 1107 and the second overflow water retaining rib 1108 are all spaced from the front side wall 1201 of the water retaining member 12, so as to guide the overflow water flow to flow smoothly into the second water channel 1205. In addition, in order to prevent the overflow water flow from flowing upward, the upper sides of the first overflow water retaining rib 1107 and the second overflow water retaining rib 1108 can be respectively abutted against the water retaining member 12, so as to guide the overflow water flow to flow downward along the second water channel 1205. That is, the end of the first water channel 1109 that is connected to the water collecting chamber 1110 inside the water collecting tray 1101 is the water inlet end, and the end outside the water collecting tray is the water outlet end.

In order to guide the condensed water collected in the water collecting tray to be discharged outward from the overflow port 1103, the first overflow water retaining rib 1107 and the second overflow water retaining rib 1108 provided on the left and right sides of the overflow port 1103 can protrude and extend into the water collecting tray 1101 respectively, so as to guide the condensed water in the water collecting tray 1101 that exceeds the water level of the overflow port 1103 to flow toward the overflow port 1103.

Optionally, in an embodiment of the present application, in order to improve the smoothness of the overflow of the overflow water flow and improve the collection efficiency of the water collecting tray 1101 for condensed water, a circle of inwardly protruding ribs is provided on the inner wall of the water collecting tray 1101, and the ribs are at the same height as the bottom of the overflow port 1103, and the ribs have notches for the overflow water flow to pass through, which are opened opposite to the overflow port 1103 above and below, and the ends of the ribs at the notches are integrally connected to the lower ends of the first overflow water retaining ribs 1107 and the second overflow water retaining ribs 1108 on the left and right sides of the overflow port 1103, thereby ensuring that the condensed water flowing from above will not directly enter the overflow port 1103, and the overflow water flow can be smoothly discharged through the overflow port 1103.

In the embodiment of the present application, the water collecting tray 1101 is a strip-shaped groove extending along the left and right directions of the air-conditioning indoor unit 1. An overflow port 1103 can be respectively opened at different left and right directions at the same height on the upper part of the water collecting tray 1101, and each overflow port 1103 is respectively connected to an overflow channel 11, so that each overflow port 1103 is connected to the air outlet 113 provided on the shell 10 through different overflow channels 11, so as to achieve the effect of overflowing and discharging condensed water at different directions through different overflow channels 11. Optionally, in the embodiment of the present application, only an overflow port 1103 is opened in the middle of the left and right directions of the strip water collecting tray 1101, and the overflow port 1103 is connected to the overflow channel 11. The overflow port 1103 arranged in the middle of the water collecting tray 1101 can discharge the overflow water flow in the middle part of the water collecting tray 1101 where the water level is the highest, so that the condensed water in the water collecting tray 1101 that exceeds the overflow height can be directly discharged to the outside through the overflow port 1103, thereby greatly improving the smoothness of the overflow.

In summary, in the embodiment of the present application, an overflow channel 11 is provided on the housing 10 of the air-conditioning indoor unit 1; the overflow channel 11 includes a first water channel 1109 and a second water channel 1205, the first water channel 1109 runs through the rear side wall 1104 of the water collecting tray 1101 of the housing 10, and the second water channel 1205 is provided between the water collecting tray 1101 and the vortex tongue member 120; the outer end of the first water channel 1109 is connected to the upper end of the second water channel 1205, and the inner end of the first water channel 1109 is inside the water collecting tray 1101, and the lower end of the second water channel 1205 is connected to the outlet of the housing 10. The air vents 113 are respectively connected to form a condensate overflow channel 11 that does not contact components installed in other spaces in the air-conditioning indoor unit 1, so that the condensate overflowing in the water collecting tray 1101 can flow out smoothly from the air outlet 113 along the above-mentioned overflow channel 11, effectively preventing the occurrence of problems such as safety impact on electrical components in the air-conditioning indoor unit 1 caused by overflowing condensate after the drain outlet 1102 of the water collecting tray 1101 is blocked, and the condensate overflowing from the air outlet 113 can be observed in time by users and/or maintenance personnel, effectively improving the troubleshooting efficiency of the air conditioner.
