[0038] The embodiment of the present invention provides a floor-standing air conditioner indoor unit. Figures 1 to 9 A floor-standing type air-conditioning indoor unit according to an embodiment of the present invention will be described in detail.

[0039] In one embodiment of the present invention, the floor-standing air conditioner indoor unit comprises:

[0040] The housing 100 is provided with an air inlet 121 and an air outlet 111;

[0041] The fan 200 is installed in the housing 100, and an air outlet duct is formed between the fan 200 and the air outlet 111;

[0042] The evaporator 300 is installed in the housing 100 and is located between the air inlet 121 and the fan 200;

[0043] The air duct housing 400 is installed in the housing 100. The air duct housing 400 includes a volute 410 and a volute tongue 420. The volute 410 and the volute tongue 420 are arranged to form the air outlet duct.

[0044] The water receiving tray 500 is disposed at the bottom of the evaporator 300 and the volute 410; wherein,

[0045] The outer wall of the volute 410 is provided with drainage transverse ribs and drainage vertical ribs. The drainage transverse ribs extend in the left-right direction and are inclined downward, and the drainage vertical ribs extend in the up-down direction. The drainage transverse ribs and the drainage vertical ribs are interconnected and cooperated to drain the condensed water on the outer wall of the volute 410 to the water receiving tray 500.

[0046] Specifically, if Figure 1 and Figure 2As shown, the housing 100 includes a front housing 110 and a rear housing 120. The front housing 110 is provided with an air outlet 111 extending in the up-down direction thereof, and the rear housing 120 is provided with an air inlet 121 extending in the up-down direction thereof. The housing 100 is provided with an evaporator 300 and a fan 200 in sequence along the air outlet direction, that is, the evaporator 300 is provided on the air inlet side of the fan 200. Optionally, the fan 200 is a cross-flow fan 200. Through the operation of the cross-flow fan 200, air is introduced into the housing 100 from the air inlet 121, and is subjected to heat exchange and cooling through the evaporator 300. The cooled air enters the air outlet duct formed between the fan 200 and the air outlet 111. The air outlet duct is formed by the duct housing 400, and specifically, the air outlet duct is surrounded by a volute 410 and a volute tongue 420. It is understandable that as the cold wind continuously penetrates into the air duct shell 400, a temperature difference will appear between the outer wall of the air duct shell 400 and the air, so that the water vapor in the air will condense into condensed water on the outer wall of the air duct shell 400 (especially on the outer wall of the volute 410). As the condensed water increases, the outer wall of the air duct shell 400 will have the problem of condensed water turbulence. In the prior art, by sticking sponge or foam on the outer wall of the air duct, the air duct shell can be insulated to prevent the generation of condensed water. However, the prior art also has the following problems: the process of sticking sponge or foam is cumbersome, the production and assembly is complicated, time-consuming and labor-intensive, and the volume and weight of the air duct shell will be increased, which is not conducive to controlling the overall volume of the air conditioner indoor unit.

[0047] The technical solution of the present invention is to set drainage transverse ribs and drainage vertical ribs on the outer wall of the volute 410. The drainage vertical ribs extend in the up and down direction, which can guide the condensed water to flow downward along the left and right side walls; the drainage transverse ribs extend in the left and right directions and are set to be inclined downward, which can guide the condensed water to flow along the upper surface in the inclined direction thereof. By reasonably arranging the drainage transverse ribs and drainage vertical ribs, the condensed water can be gradually guided to the water receiving tray 500 to solve the problem of condensed water turbulence on the outer wall of the air duct; at the same time, since the large sponge and foam on the outer wall of the air duct are eliminated, the production and assembly process can be simplified, and the production efficiency is greatly improved; it is also beneficial to reduce the volume and weight of the air duct shell 400, thereby facilitating the control of the overall volume of the air-conditioning indoor unit.

[0048] In one embodiment, if Figures 3 to 7As shown, the drainage transverse ribs include a plurality of first drainage transverse ribs 401 arranged in parallel along the up-down direction, the drainage vertical ribs include a plurality of first drainage vertical ribs 405 arranged along the extension direction of the first drainage transverse ribs 401, and a plurality of first drainage vertical ribs 405 are arranged between any two first drainage transverse ribs 401, the top of each first drainage vertical rib 405 is connected to the first drainage transverse rib 401 located above it, and the bottom of each first drainage vertical rib 405 is disconnected from the first drainage transverse rib 401 located below it and arranged at intervals. It can be understood that through the drainage effect of the plurality of first drainage vertical ribs 405, the condensed water on the outer surface of the volute 410 can be drained downward to the first drainage transverse rib 401, the condensed water gradually gathers on the upper surface of the first drainage transverse rib 401, and then flows along the inclined direction of the first drainage transverse rib 401, and finally flows downward along the first drainage vertical rib 405 connected to the lowest end of the first drainage transverse rib 401. The bottom end of the first drainage vertical rib 405 is separated from the first drainage transverse rib 401 located below it and arranged at a distance to prevent the water flowing on the first drainage transverse rib 401 from being blocked, and to ensure that the water flowing on the first drainage transverse rib 401 can flow smoothly. Each first drainage transverse rib 401 and the multiple first drainage vertical ribs 405 connected thereto are a drainage unit. By arranging multiple drainage units in the up-down direction on the outer wall of the volute 410, the condensed water can be gradually drained to the lowest point of the outer wall and finally flow into the water receiving tray 500.

[0049] Furthermore, if Figure 5 and Figure 7 As shown, there is an arc transition between the lowest end of each first drainage transverse rib 401 and the top of the first drainage vertical rib 405 connected thereto. It can be understood that the condensed water collected on the first drainage transverse rib 401 will flow along the inclined direction of the first drainage transverse rib 401, and then flow downward along the first drainage vertical rib 405 connected to the lowest end of the first drainage transverse rib 401. By setting the lowest end of the first drainage transverse rib 401 and the top of the first drainage vertical rib 405 connected thereto as an arc transition, the water flow resistance can be reduced, so as to smoothly guide the water flow from the first drainage transverse rib 401 to the first drainage vertical rib 405.

[0050] Furthermore, if Figure 5As shown, the outer wall of the volute 410 is also provided with a first flow-guiding vertical rib 411 extending in the up-down direction, and a water flow channel is formed between the first flow-guiding vertical rib 411 and the first flow-guiding vertical rib 405 adjacent thereto, and a drain port 415 of the water flow channel is located above the water receiving tray 500. In this embodiment, the first flow-guiding vertical rib 411 extends in the up-down direction through the entire outer area of ​​the volute 410, and a water flow channel is formed between the first flow-guiding vertical rib 411 and the plurality of first flow-guiding vertical ribs adjacent thereto, and the condensed water on each first flow-guiding horizontal rib 401 will flow toward the water flow channel and eventually converge in the water flow channel. It can be understood that the bottom opening of the water flow channel forms a drain port 415, and the drain port 415 must be located within the water receiving range of the water receiving tray 500. Among them, the outer wall corresponding to the drain port 415 can be recessed inward to form a turbulent zone, so as to facilitate guiding the flowing water to maintain a downward flow trend.

[0051] Furthermore, a plurality of transverse reinforcing ribs 414 are provided on the side of the first flow-guiding vertical rib 411 facing away from the water flow channel, and the plurality of transverse reinforcing ribs 414 are arranged in parallel in the up-down direction. It can be understood that, since the length of the first flow-guiding vertical rib 411 is relatively long, by adding transverse reinforcing ribs 414 on the side facing away from the water flow channel, the strength of the first flow-guiding vertical rib 411 can be effectively strengthened to avoid its breakage. In addition, by connecting the transverse reinforcing ribs 414 to the long side of the volute 410, the overall strength of the volute 410 can also be strengthened.

[0052] In another embodiment, if Figure 8 As shown, the drainage transverse ribs include multiple layers of second drainage transverse ribs 402, and each layer of second drainage transverse ribs 402 includes multiple second drainage transverse ribs 402 arranged at intervals; the drainage vertical ribs include multiple layers of drainage vertical ribs, and each layer of drainage vertical ribs includes second drainage vertical ribs 406 and third drainage vertical ribs 407 arranged at staggered intervals, and any two adjacent second drainage transverse ribs 402 located in different layers are connected end to end through the second drainage vertical ribs 406; the top of each third drainage vertical rib 407 is connected to the second drainage transverse rib 402 located above it, and the bottom of each third drainage vertical rib 407 is disconnected from the second drainage transverse rib 402 located below it. In this embodiment, the flow path of the condensed water is designed in a stepped shape, which can also guide the condensed water to flow gradually downward, and prevent the condensed water from flowing turbulently on the outer wall of the volute 410 and failing to gather in the water receiving tray 500.

[0053] In this embodiment, the outer wall of the volute 410 is also provided with a first flow-guiding vertical rib 411, and a water flow channel is formed between the first flow-guiding vertical rib 411 and the adjacent third flow-guiding vertical rib 407. The condensed water on each second flow-guiding transverse rib 402 will flow toward the water flow channel and eventually gather in the water flow channel, and a drain port 415 is also provided at the bottom of the water flow channel, and the collected condensed water in the water flow channel eventually flows into the water receiving tray 500 through the drain port 415.

[0054] In yet another embodiment, Fig. 9 As shown, the drainage transverse ribs include a left-direction drainage transverse rib 403 extending to the left and tilted downward, and a right-direction drainage transverse rib 404 extending to the right and tilted downward, the left-direction drainage transverse rib 403 and the right-direction drainage transverse rib 404 are arranged alternately in the up and down directions, and the drainage vertical ribs include a fourth drainage vertical rib 408 and a fifth drainage vertical rib 409, and the nearest ends between the left-direction drainage transverse rib 403 and the right-direction drainage transverse rib 404 are connected by the fourth drainage vertical rib 408; a plurality of fifth drainage vertical ribs 409 are arranged between the left-direction drainage transverse rib 403 and the right-direction drainage transverse rib 404, the top end of each fifth drainage vertical rib 409 is connected to the drainage transverse rib located above it, and the bottom end of each fifth drainage vertical rib 409 is disconnected from the drainage transverse rib located below it and arranged at intervals. In this embodiment, the water flow can flow toward the left side and tilt downward, or it can flow to the right side and tilt downward. Through the drainage effect of the drainage vertical ribs located on the leftmost and rightmost sides of the drainage horizontal ribs, the condensed water will gather on the left and right sides of the outer wall of the volute 410 and form a downward-flowing water flow.

[0055] Furthermore, in addition to the first flow-guiding vertical rib 411, the outer wall of the volute 410 is also provided with a second flow-guiding vertical rib 412 arranged opposite to the first flow-guiding vertical rib 411, and a plurality of downwardly bent flow-guiding short ribs 413 are arranged on the side of the second flow-guiding vertical rib 412 close to the flow-guiding transverse rib, the highest end of the flow-guiding short rib 413 is connected to the second flow-guiding vertical rib 412, and the lowest end of the flow-guiding short rib 413 is disconnected from the left flow-guiding transverse rib and arranged at intervals. In this embodiment, in addition to the first water flow channel formed between the first flow-guiding vertical rib 411 and the flow-guiding vertical rib, the second water flow channel is also formed between the second flow-guiding vertical rib 412 and the flow-guiding vertical rib, so that the condensed water on the outer wall of the volute 410 flows downward through the two water flow channels, which is equivalent to increasing the rate at which the condensed water is discharged from the outer wall of the volute 410. Furthermore, the first water flow channel is provided with a drain port 415 at its bottom end, and the condensed water in the second water flow channel will also be collected in the first water flow channel through the drainage transverse ribs located at the lowest side, and finally flow into the water receiving tray 500 through the drain port 415.

[0056] In the embodiment of the present invention, Figure 3 As shown, the angle α between the drainage transverse rib and the horizontal direction is in the range of 0°<α<90°, and optionally, the value range of α is 15°~45°. It can be understood that by properly tilting the drainage transverse rib downward at a certain angle, it can not only ensure that the drainage transverse rib can receive the condensed water guided by multiple drainage vertical ribs, but also make the water flow have a downward flow tendency, so as to finally smoothly guide the condensed water into the water receiving tray 500.

[0057] Furthermore, if Figure 4 As shown, the angle β between the top surface of the drainage transverse rib and the vertical direction ranges from 0° to 90°, and optionally, the value range of β is 15° to 45°. That is, the drainage transverse rib will be tilted upward from the connection with the volute 410, so that the drainage transverse rib can well receive the condensed water guided by the drainage vertical rib, and prevent the condensed water from spilling out. It should be noted that since the volute 410 is not necessarily set perpendicular to the ground, the volute 410 can be slightly tilted away from the vertical direction. Therefore, the angle between the top surface of the drainage transverse rib and the vertical direction is not necessarily the same as the angle between the top surface of the drainage transverse rib and the outer side surface of the volute 410.

[0058] The embodiment of the present invention further provides an air conditioner, which includes an air conditioner outdoor unit and a floor-standing air conditioner indoor unit, and the air conditioner outdoor unit and the floor-standing air conditioner indoor unit are connected through a refrigerant pipe. The specific structure of the floor-standing air conditioner indoor unit refers to the above embodiment. Since the air conditioner adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here one by one.

[0059] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
