The good fixation in the casing 50 helps to improve the installation stability of the volute 2.

It should be noted that, in this embodiment, the central partition 1 is provided in the middle of the cabinet 50 to divide the cabinet 50 into an indoor chamber and an outdoor chamber that are arranged up and down. The mobile air conditioner also includes The indoor side heat exchanger 200, the outdoor side heat exchanger (not shown in the figure), and the outdoor side heat exchange air duct (not shown in the figure), wherein the indoor side heat exchanger 200 is arranged in the indoor side chamber, and the volute 2 The indoor side heat exchange air duct is formed inside, and the indoor side heat exchange air duct has an air inlet and an air outlet. There are various specific installation positions of the air inlet and the air outlet, but in this embodiment, the optional air inlet is formed in the volute 2 The upper side is close to the indoor side heat exchanger 200 and communicates with the indoor side heat exchanger 200, and the air outlet is formed at the upper end of the volute 2 to extend the path length of the indoor side heat exchange air duct. The outdoor side heat exchanger is arranged in the outdoor side chamber, and the outdoor side heat exchange air ducts are respectively connected to the outdoor side heat exchanger and the indoor side heat exchange air duct. The mobile air conditioner uses the indoor side heat exchanger 200 and the outdoor side heat exchanger to exchange details. The thermal principle can refer to the prior art, which will not be described in detail here.

In addition, in this design, the fixed structure is arranged around the volute 2, that is, arranged on the periphery of the volute 2 along the circumferential direction of the central partition 1, wherein the fixed structure may be continuous along the circumferential direction of the central partition 1. The arrangement structure, in one embodiment, the fixing structure is embodied as a ring-shaped rib, which is arranged around the periphery of the volute 2, and the ring-shaped rib and the central partition 1 jointly define a mounting groove, wherein, The ring inner size of the annular rib is matched with the outer contour size of the corresponding part of the volute 2, so that the mounting groove can be just clamped to the volute 2 to realize the fixed installation of the volute 2; of course, the fixed structure can also be along the volute.
