[0041] In the embodiment of the present application, the housing 10 includes a bottom shell part 110 as an example for expansion and discussion: The bottom shell part 110 includes a back plate 111 constituting the rear side wall of the housing 10 and a lower side plate 112 constituting the lower side wall of the housing 10. The lower side of the back plate 111 is integrally connected to the rear side of the lower side plate 112. An air outlet 113 of the housing 10 is provided on the lower side plate 112. In addition, a water collecting tray 1101 for collecting condensed water generated inside the housing 10 is integrally provided on the lower side plate 112. The water collecting tray 1101 can also be integrally provided on other components of the housing 10 or can be an independent part fixedly installed on the housing 10, etc. The above deformations all fall within the protection scope of the present application and will not be repeated here.

The drain port 1102 is generally provided at the bottom of the water collecting tray 1101 and is connected to an external drain pipe for discharging the condensed water collected by the water collecting tray 1101 to the outside, so as to effectively collect and discharge the condensed water generated inside the housing 10 of the air conditioner indoor unit 1.

[0043] Meanwhile, to solve the problem that the condensed water cannot be smoothly discharged outside after the drain port 1102 is blocked, in the embodiment of the present application, a water baffle 12 is further installed inside the housing 10 on one side of the water collecting tray 1101. The water baffle 12 can be a part of the housing 10, or other independent components installed on the housing 10, or a part of other components installed inside the housing 10, etc. The water collecting tray 1101 and the outer water baffle 12 together form an overflow channel 11. The upper and lower ends of the overflow channel 11 are respectively connected to the inside of the water collecting tray 1101 and the air outlet 113 provided on the housing 10, so that the condensed water in the water collecting tray 1101 after the drain port 1102 is blocked can be discharged outward along the overflow channel 11 and through the air outlet 113, thereby effectively preventing the overflowing condensed water from coming into contact with the components installed in other spaces inside the housing 10.

[0047] As Figures 1 to 9 Shown in the figure, an embodiment of the present application provides an indoor air conditioner 1, which includes a housing 10; the housing 10 includes a bottom shell member 110 that constitutes the rear side and the lower side of the housing 10; an air outlet 113 is provided on the bottom shell member 110 at the front side position of the bottom of the housing 10, and a turbine fan structure 20 is installed in the middle of the housing 10. 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. 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 housing 10 itself, and / or additional components installed on the housing 10, so that the air flow generated by the turbine fan structure 20 flows through the air outlet duct 30 and flows out from the air outlet 113.

[0048] In an embodiment of the present application, a water collecting tray 1101 is further installed on the front side of the housing 10 at the lower part. The water collecting tray 1101 is a groove structure integrally provided on the lower side plate 112 of the bottom shell member 110, and the water collecting tray 1101 is located below the housing 10 near the front side; the upper side of the water collecting tray 1101 is open, so that the condensed water generated inside the housing 10 can flow downward along the inner wall of the housing 10 and flow into the water collecting tray 1101, thereby achieving the effect of collecting the condensed water inside the housing 10.

[0049] In an embodiment of the present application, a drain port 1102 communicating with the outside is further connected to the water collecting tray 1101. The drain port 1102 is generally connected to the bottommost part of the water collecting tray 1101, so that all the condensed water collected in the water collecting tray 1101 can be discharged out from the drain port 1102; at the same time, in order to improve the drainage smoothness, a joint extending downward and outward is generally provided at the drain port 1102, and the joint is connected to an external drain pipe, so that the condensed water flowing out from the drain port 1102 can flow smoothly into the drain pipe under the action of gravity and then be discharged outward.

[0050] In the embodiment of the present application, a water baffle 12 is further provided inside the housing 10. The water baffle 12 is located on one side of the water collecting tray 1101. The corresponding side wall of the water collecting tray 1101 and the water baffle 12 provided on the outside jointly enclose an overflow channel 11. The upper and lower ends of the overflow channel 11 are respectively communicated with the inside of the water collecting tray 1101 and the air outlet 113 provided on the housing 10, so that the condensed water overflowing in the water collecting tray 1101 can be discharged outward through the overflow channel 11 and the air outlet 113, thereby preventing the overflowing condensed water from flowing into other spaces inside the housing 10 of the air conditioner indoor unit 1 and effectively eliminating the safety hazards caused by the overflowing condensed water to the electrical components inside the housing 10 of the air conditioner indoor unit 1; at the same time, the overflowing condensed water directly flows through the overflow channel 11 to the air outlet 113, so that the overflowing condensed water flows into the air path of the indoor air conditioner 1 only through the overflow channel 11, shortening the flow path of the condensed water and further preventing the condensed water from contacting other components; in addition, the overflowing condensed water directly flows to the air outlet 113, and under the action of the external exhaust air flow at the air outlet 113, the overflowing condensed water will be blown out of the housing 10 along with the air flow, which not only avoids the situation of the condensed water flowing back into the housing 10, but also enables users and / or maintenance personnel to directly observe the overflowing condensed water flow, effectively improving the maintenance efficiency of the air conditioner indoor unit 1.

[0051] In the embodiment of the present application, a turbine fan structure 20 is provided inside the housing 10. The water baffle 12 is a volute tongue member 120 provided on the outer periphery of the outlet 201 of the turbine fan structure 20; there is a gap cavity 13 between the volute tongue member 120 and the side wall of the water collecting tray 1101 facing the turbine fan structure 20. The gap cavity 13 is wholly or partially partitioned to form a water channel, and the above water channel directly or jointly with other water channels forms the overflow channel 11; the upper part of the overflow channel 11 is communicated with the upper part of the water collecting tray 1101 through an overflow port 1103 passing through the side wall of the water collecting tray 1101; the lower part of the overflow channel 11 is communicated with the air outlet 113 provided on the housing 10 through an overflow drain port 1204 opened downward on the volute tongue member 120. Of course, in the embodiment of the present application, the volute member 120 is taken as an example of the water baffle 12 for discussion, but the water baffle 12 can also be composed of other components, and will not be separately discussed in this embodiment, but the protection scope of the present application covers the implementation manners in which the above other components are used as the water baffle 12. Optionally, the outlet 201 of the turbine fan structure 20 is communicated with the air outlet 113 through an air outlet duct 30, and the lower end of the overflow channel 11 is communicated with the air outlet duct 30 through an overflow drain port 1204 opened downward on the volute tongue member 120, so that the overflow water flowing out from 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 is blown by the air flow in the air duct to all flow to the air outlet 113 and is smoothly discharged from the housing 10 of the air conditioner indoor unit, thereby effectively avoiding the residue of the overflow water in the housing 10.

[0052] In the embodiment of the present application, a turbine fan structure 20 is arranged inside the housing 10, and the water baffle 12 is a volute tongue member 120 arranged on the outer peripheral side of the outlet 201 of the turbine fan structure 20; the volute tongue member 120 is an arc-shaped plate arranged in front 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 extending along a similar arc. The above-mentioned arc-shaped plate forms a water guiding portion 121. The upper side of the water guiding portion 121 formed by the arc-shaped plate is connected to the top of the volute casing 203 and the rear side wall 1104 of the water collecting tray 1101; there is a gap between the front side of the water guiding portion 121 formed by the arc-shaped plate and the outer wall surface of the rear side wall 1104 of the water collecting tray 1101, and the above-mentioned gap forms a gap cavity 13; the lower side of the water guiding portion 121 formed by the arc-shaped plate is provided with a bent portion 122 bent forward, and the lower end of the bent portion 122 is connected with an extending portion 123 extending forward. The extending portion 123 extends below the water collecting tray 1101, and the extending portion 123 is in contact with and fits against the lower side of the bottom wall 1105 of the water collecting tray 1101;

[0053] Optionally, the lower extending portion 123 of the volute tongue member 120 is in contact with and fixedly connected to the bottom wall 1105 of the water collecting tray 1101, so that the upper and lower sides of the volute tongue member 120 are respectively fixedly connected to the housing 10. Through the above arrangement, a gap cavity 13 that gradually widens in the front-rear dimension from top to bottom is formed between the volute tongue member 120 and the rear side wall 1104 of the water collecting tray 1101, so that the overflow condensate water flowing in from the upper side can flow downward under the action of gravity and will not be unable to flow downward due to the action of internal air pressure or the like. Furthermore, the drainage rate of the overflow condensate water is greatly improved, and the overflow condensate water can flow quickly and smoothly in the direction of the air outlet 113 through the overflow channel 11.

[0054] In the embodiment of the present application, there is a clearance cavity 13 between the volute tongue member 120 and the side wall of the water collecting tray 1101 facing the turbine fan structure 20. An overflow channel 11 is provided in the clearance cavity 13. The overflow channel 11 can be constituted by the whole of the clearance cavity 13 or by a part of the clearance cavity 13. In the embodiment of the present application, in order to reduce the flow area of the overflow condensate, a part of the clearance cavity 13 is isolated by a first water retaining rib 1202 and a second water retaining rib 1203 to form a second water channel 1205. The second water channel 1205 is used for the overflow condensate to flow through the spacer cavity 13 and then flow to the air outlet 113, thereby effectively reducing the diffusion space of the overflow condensate and enabling the overflow condensate to flow quickly and concentratedly along the second water channel 1205. At the same time, the upper part of the second water channel 1205 is connected to the upper space inside the water collecting tray 1101 through a first water channel 1109 passing through the rear side wall 1104 of the water collecting tray 1101. The lower part of the second water channel 1205 is connected to the air outlet 113 provided on the housing 10 through an overflow drain port 1204 opened downward on the volute tongue member 12. Optionally, the overflow drain port 1204 is located at the bent portion 122 of the volute tongue member 120, so that the overflow drain port 1204 is located at the lowest point and the widest radial width of the entire volute tongue member 120, so that no air resistance is generated at the overflow drain port 1204 due to the internal air pressure of the water channel, resulting in the situation that the overflow condensate cannot be completely discharged. That is, the overflow channel 11 is constituted by the above-mentioned first water channel 1109, second water channel 1205, and overflow drain port 1204 connected in sequence, so as to conduct the water collecting tray 1101 and the air outlet 113.

[0055] In the embodiment of the present application, two water retaining ribs are provided on the side of the volute tongue member 120 facing the clearance cavity 13, namely a first water retaining rib 1202 and a second water retaining rib 1203. The first water retaining rib 1202 and the second water retaining rib 1203 extend vertically and are arranged at intervals. The gap between the first water retaining rib 1202 and the second water retaining rib 1203 and the front side wall 1201 of the volute tongue member 120 together enclose a second water channel 1205 extending vertically. The rear sides of the first water retaining rib 1202 and the second water retaining rib 1203 are integrally connected to the front side wall 1201 of the volute tongue member 120, and the front sides both extend to abut against the rear outer wall of the water collecting tray 1101, so that the four directions of the front, rear, left, and right of the second water channel 1205 are respectively closed, so as to guide the overflow water flow to flow downward along the second water channel 1205 under the action of gravity.

[0056] 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 out of the drain port 1102. At the same time, in order to guide the smooth flow of the overflow condensed water 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 reaching the water level of the overflow port 1103 in the water collecting tray 1101 to overflow into the second water channel 1205.

[0057] 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. On the left and right sides of the overflow port 1103, a first overflow water retaining rib 1107 and a second overflow water retaining rib 1108 protruding outward from the water collecting tray 1101 are respectively arranged. The horizontally 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 walls of the corresponding overflow water retaining ribs are in relative abutment with the inner side walls of the water retaining ribs, so as to form a reliable water passing waterway at the connection of the first water channel 1109 and the second water channel 1205, effectively preventing the overflow water flow from leaking at the connection of the two water channels. At the same time, in order to guide the water flowing into the second water channel 1205 through the overflow port 1103, a water guiding rib 1106 protruding and extending into the second water channel 1205 can be arranged on the lower side of the overflow port 1103. The left and right sides of the water guiding rib 1106 are integrally connected to the lower sides of the first overflow water retaining rib 1107 and the second overflow water retaining rib 1108 respectively, and there are gaps between the rear end sides of the water guiding rib 1106, the first overflow water retaining rib 1107 and the second overflow water retaining rib 1108 and the front side wall 1201 of the water retaining member 12 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 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 connected to the internal water collecting cavity 1110 of the water collecting tray 1101 is the water inlet end, and the end outside the water collecting tray is the water outlet end.

[0058] 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 arranged on the left and right sides of the overflow port 1103 can respectively protrude and extend into the water collecting tray 1101 to guide the condensed water in the water collecting tray 1101 exceeding the water level height of the overflow port 1103 to flow toward the overflow port 1103.

[0059] Optionally, in the embodiments of the present application, in order to improve the smoothness of the overflow of the overflow water flow and enhance the collection efficiency of the condensate by the water collecting tray 1101, a ring of inwardly protruding ribs is provided on the inner wall of the water collecting tray 1101. The ribs are at the same height as the bottom of the overflow port 1103, and there are openings on the ribs for the overflow water flow to pass through, which are vertically opposite to the overflow port 1103. The end of the rib at the opening is 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, so as to ensure that the condensate flowing from top to bottom does not directly enter the overflow port 1103, and the overflow water flow can smoothly overflow and be discharged outward through the overflow port 1103.

[0060] In the embodiments of the present application, the water collecting tray 1101 is a strip-shaped groove extending in the left and right directions of the air conditioner indoor unit 1. An overflow port 1103 can be respectively opened at different left and right positions at the same height in the upper part of the water collecting tray 1101, and each overflow port 1103 is connected to an overflow channel 11. Each overflow port 1103 is respectively communicated with the air outlet 113 provided on the housing 10 through different overflow channels 11, so as to achieve the effect of overflowing and discharging the condensate at different positions through different overflow channels 11. Optionally, in the embodiments of the present application, only one overflow port 1103 is opened at the middle position in the left and right directions of the strip-shaped water collecting tray 1101. The above-mentioned overflow port 1103 is connected to the overflow channel 11. The overflow port 1103 provided in the middle of the water collecting tray 1101 can discharge the overflow water flow at the middle position where the water level in the water collecting tray 1101 is the highest, so that the condensate in the water collecting tray 1101 exceeding the overflow height can be directly discharged outward through the overflow port 1103, greatly improving the smoothness of the overflow water.

[0061] In summary, in the embodiments of the present application, an overflow channel 11 is provided on the housing 10 of the air conditioner indoor unit 1; the overflow channel 11 includes a first water channel 1109 and a second water channel 1205. The first water channel 1109 is formed by a through hole in the rear side wall 1104 of the water collecting tray 1101 of the housing 10, and the second water channel 1205 is arranged between the water collecting tray 1101 and the volute tongue member 120; the outer end of the first water channel 1109 is communicated with the upper end of the second water channel 1205, and the inner end of the first water channel 1109 is communicated with the inside of the water collecting tray 1101, and the lower end of the second water channel 1205 is communicated with the air outlet 113 of the housing 10 respectively, so as to form a condensate overflow channel 11 that does not contact the components installed in other spaces in the air conditioner indoor unit 1, so that the condensate overflowing in the water collecting tray 1101 can smoothly flow out from the air outlet 113 along the above-mentioned overflow channel 11, effectively preventing problems such as the condensate overflowing after the drain port 1102 of the water collecting tray 1101 is blocked from causing safety impacts on the electrical components in the air conditioner indoor unit 1, and enabling the condensate overflowing from the air outlet 113 to be observed by users and / or maintenance personnel in time, effectively improving the fault troubleshooting efficiency of the air conditioner.
