For the indoor unit of a floor type air conditioner, a cross flow fan is generally used as the fan. The air duct assembly structure in the embodiment forms two fan installation positions for installing the cross-flow fan, and the two fans can be installed at the same time, so that large air volume air outlet is realized. As viewed in the orientation of fig. 1, the second air duct member 11 is located above the first air duct member 10, and the liquid inlet/outlet pipe 12 is sandwiched between the first air duct member 10 and the second air duct member 11.

It should be noted that the orientation shown in fig. 1 is not the actual installation orientation of the air duct member in the air conditioning indoor unit, and since the air duct assembly is applied to the floor air conditioning indoor unit, the length direction of the air duct assembly extends in the vertical direction during actual installation.

As shown in fig. 1 and 2, the liquid inlet and outlet pipe 12 is disposed at a long side of the air duct member, and most of the pipe extends in a length direction of the air duct assembly except for a portion connected to the indoor heat exchanger. In order to stably fix the liquid inlet and outlet pipes 12 to the air duct assembly, in this embodiment, a pressing portion 111 is provided on the second air duct member 11 in the air duct assembly, and in a state that the installation is completed, that is, after the first air duct member 10 is fastened and connected with the second air duct member 11, the pressing portion 111 of the second air duct member 11 and an extending portion (not labeled) formed on the first air duct member 10 and used for supporting the liquid inlet and outlet pipes 12 together form a pipe constraining space 13. In the prior art, the extension is used to connect to a tube platen separate from the first tunnel member 10 to secure the inlet and outlet tubes 12.

Further, the fasteners in the above embodiments may be screws, bolts, or the like.

In addition, the reinforcing part 1115 in the above-described embodiment is designed as a cylindrical structure, and alternatively, the reinforcing part may be one or two reinforcing ribs.

Since the air conditioning indoor unit 1 has a longitudinal direction as to the installation position of the pressure contact portion 111, the pressure contact portion 111 is preferentially installed on the long side of the air conditioning indoor unit 1, and if the liquid inlet/outlet pipe 12 needs to be bent to avoid another structure, the pressure contact portion 111 can be adaptively adjusted to the short side.

Regarding the air-conditioning indoor unit, although a vertical air-conditioning indoor unit is taken as an example in the present embodiment, it can be understood that the present invention is also applicable to a hanging type air conditioner, a window type air conditioner, and the like.

In the above embodiment and various expanded embodiments, the crimping portion 111 is connected with the first air duct member 10 to form the pipeline constraint space 13, and compared with the prior art in which the liquid inlet/outlet pipe 12 is fixed by using a pipe pressing plate, one part and one set of mold are reduced, so that the operation is convenient, omission is avoided, the design cost is reduced, and the production efficiency is improved.

So far, the technical solution of the present invention has been described with reference to the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is not limited to these specific embodiments. Without departing from the principle of the present invention, a person skilled in the art can make equivalent changes or substitutions to the related technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
