Description

Indoor unit of air conditioner Technical Field The invention relates to the technical field of air conditioners, in particular to an air conditioner indoor unit. Background Air conditioners have been widely used in modern society as common electric appliances. In the existing indoor unit of the air conditioner, in order to facilitate the ventilation of the heat exchanger, the heat exchanger is generally arranged near the air port, and an integral water receiving disc is required to be arranged below the center of the heat exchanger for collecting condensed water in the traditional scheme, however, the transversely extending structure of the water receiving disc can directly block the air supply path of the middle air duct, the wind resistance is obviously increased, vortex is formed, and the problems of air supply efficiency reduction, operation noise increase and the like are caused. Especially in the application scene that needs the increase air supply volume, this structural defect is more prominent. While attempts have been made in the prior art to improve windage by optimizing the structure of the water tray (e.g., reducing the thickness, etc.), the improvement has been limited by the spatial coupling relationship of the water tray to the direction of the heat exchanger opening. Therefore, a new structural design scheme capable of effectively collecting condensed water and reducing wind resistance is needed. Disclosure of Invention The invention aims to provide an air conditioner indoor unit with good heat exchange effect and high air supply efficiency. The invention discloses an air conditioner indoor unit, comprising: A housing; the air port component comprises a bottom air channel port assembly arranged at the lower end of the shell; The heat exchanger is arranged in the shell and is positioned above the bottom air duct opening assembly, and comprises a first heat exchange part and a second heat exchange part, one ends of the first heat exchange part and the second heat exchange part are mutually connected, and the first heat exchange part and the second heat exchange part form an inverted V-shaped structure with an opening facing the bottom air duct opening assembly; The fan component is arranged in the shell and is positioned above the heat exchanger; The water receiving component comprises a first water receiving disc and a second water receiving disc, the first water receiving disc is arranged below the end part of the first heat exchange part, which is far away from the second heat exchange part, and is used for receiving condensed water at the end part, and the second water receiving disc is arranged below the end part of the second heat exchange part, which is far away from the first heat exchange part, and is used for receiving condensed water at the end part; Wherein, during air supply operation, wind flows through the bottom duct opening assembly, the fan component drives wind into the housing and the wind exchanges heat with the heat exchanger during the flow of the wind in the housing. The indoor unit of an air conditioner of this embodiment is through setting up the heat exchanger to the reverse V-arrangement structure including first heat transfer portion and second heat transfer portion to set up the heat exchanger in the top of bottom air duct mouth and with the opening towards bottom air duct mouth, and set up two water collector and arrange respectively in the below both ends of reverse V-arrangement structure and accept the comdenstion water respectively, owing to set up the water collector separately, the water collector can be made littleer, and two water collector are located both sides, when this structure sets up the comdenstion water that can high-efficient accept the heat exchanger, and can avoid the blocking to the middle part region of heat exchanger, reduce the windage with the wind of heat transfer of heat exchanger, improve heat transfer effect and air supply efficiency. In some embodiments, the water collecting device further comprises a water discharging pipeline arranged at the lower end of the shell, and the water discharging pipeline is communicated with the first water collecting disc and the second water collecting disc. In this embodiment, since the water receiving tray is disposed in the bottom area of the indoor unit of the air conditioner, the drain pipeline at the lower end for draining the condensed water received by the water receiving tray can be designed to be shorter, and the structural design can be simpler. In some embodiments, the air conditioning indoor unit has a first state, in which the air conditioning indoor unit is in an air supply operation, the fan component drives air to enter the shell and output the air to the heat exchanger, and flows out from the bottom air duct port assembly to the outside after the air exchanges heat with the heat exchanger, and the air conditioning indoor unit further has an air guiding structure arranged between th
