The working motor 21 is fixedly disposed on the motor mounting position 12, and the rotating fan 22 is fixedly disposed on the output shaft of the working motor 21 and is located in the heat exchange air duct 11. When the working motor 21 is operated, the rotating fan 22 is driven to rotate, thereby the rotating fan 22 drives the heat exchange air duct 11 to generate airflow to achieve heat exchange;

In addition, the installation structure can be reduced in the one-piece injection molding method, making the overall structure simpler and more compact, so that the overall volume is smaller.

[0046] Specifically, the front side of the air duct shell 1 in this embodiment is provided with an air outlet 111 in the shape of a circular hole to connect the heat exchange air duct 11 with the outside world. In addition, the air duct shell 1 is provided with a motor mounting seat 121 suspended at the air outlet 111 and a plurality of connecting parts 122 arranged along the circumference of the air outlet 111. One end of the length of each connecting part 122 is vertically connected to the air duct shell 1, and the other end of the length extends inward along the radial direction of the air outlet 111 and is connected to the motor mounting seat 121. In addition, the motor mounting position 12 is set on the motor mounting seat 121.

[0047] Therefore, the fan motor 2 is installed on the motor mounting position 12 on the suspended motor mounting seat 121 so that the fan motor 2 is centered relative to the air outlet 111 to facilitate air outlet.

[0048] Preferably, each connecting member 122 is in the shape of a long strip, and the thickness direction of the connecting member 122 and the direction of the air outlet 111 are perpendicular to each other, so that the contact area between the wind blown out from the air outlet 111 and the connecting member 122 is smaller, thereby reducing wind resistance.

[0049] Preferably, the motor mounting base 121 in this embodiment is provided with a recessed embedded cavity 123 on the rear side, and the working motor 21 is partially placed in the embedded cavity 123 for positioning and partially extends out of the embedded cavity 123 to enter the heat exchange air duct 11, wherein the extended part of the working motor 21 is fixed to the motor mounting base 121 by means of bolts to achieve a more stable installation of the working motor 21.

[0050] In addition, the electrical control box 14 in this embodiment includes a main body 141 and a box cover 142. The main body 141 is integrally formed on the air duct shell 1. A box cavity 1411 is formed in the main body 141. The main control board 4 is arranged in the box cavity 1411. The box cover 142 can be removably installed on the main body 141 to seal the box cavity 1411.

[0052] Among them, the capacitor assembly includes a cylindrical first capacitor 31, and the capacitor mounting position includes a first mounting position 131 located above the front side of the air duct shell 1; wherein, the air duct shell 1 is provided with a deformable part 133 at the first mounting position 131, one end of the deformable part 133 is integrally formed with the air duct shell 1, and the other end serves as a free end 1331 and extends upward, and a disassembly opening 1332 is formed between the free end 1331 and the air duct shell 1. In the natural state of the deformable part 133, the width of the disassembly opening 1332 is smaller than the diameter of the first capacitor 31, so that the deformable part 133 is bent to enlarge the disassembly opening 1332 so that the first capacitor 31 can be placed between the deformable part 133 and the air duct shell 1, and then the first capacitor 31 is clamped and fixed by resetting the deformable part 133.

[0053] Preferably, the deformable member 133 in this embodiment is provided with a positioning abutment 1333 to abut against the first capacitor 31 and limit the movement of the first capacitor 31 toward the disassembly port 1332; in addition, the air duct shell 1 is integrally formed with positioning members 1334 for positioning the first capacitor 31 at the left and right ends of the first capacitor 31, so that the upward movement is restricted by the positioning abutment 1333, and the positioning member 1334 restricts the left and right movement to ensure the stability of the installation of the first capacitor 31.

[0054] Among them, the capacitor assembly includes a cylindrical second capacitor 32, and the capacitor mounting position includes a second mounting position 132 located above the left side of the air duct shell 1; wherein, the air duct shell 1 is integrally formed with a second mounting seat 134 at the second mounting position 132, and a semicircular second groove 1341 is provided on the left side of the second mounting seat 134. A clamping member 135 is detachably provided on the second mounting position 132, and a semicircular first groove 1351 is provided on the clamping member 135. The second capacitor 32 is surrounded by the first groove 1351 and the second groove 1341 and clamped between the second mounting seat 134 and the clamping member 135.

[0055] Preferably, the clamping member 135 is a sheet-like structure and is in the shape of an arch bridge due to the setting of the second groove 1341; the clamping member 135 is provided with mounting portions 1352 at both ends of its length, and a perforation is provided on the mounting portion 1352, and a corresponding screw hole is opened on the second mounting seat 134, so that the bolt passes through the perforation on the mounting portion 1352 and is threadedly matched with the screw hole on the second mounting seat 134 to achieve installation.

[0056] It should be noted that the first capacitor 31 and the second capacitor 32 are both used to operate the compressor. In this embodiment, the first capacitor 31 and the second capacitor 32 are set. In other embodiments, only the first capacitor 31 or the second capacitor 32 may be set. Correspondingly, when only the first capacitor 31 is set, since the second capacitor 32 is not set, there is no need to set up a structure for installing the second capacitor 32. Similarly, when only the second capacitor 32 is set, since the first capacitor 31 is not set, there is no need to set up a structure for installing the first capacitor 31.

[0057] Preferably, the air duct shell 1 in this embodiment includes a shell base 15 and a heat exchange plate 16, and a heat exchange channel or heat exchange tube is arranged in the heat exchange plate 16. In addition, the shell base 15 includes a front plate body 151 and a volute-shaped side plate body 152. The side plate body 152 is integrally formed on the rear side of the front plate body 151, and the heat exchange plate 16 is arranged on the rear side of the side plate body 152 and is detachably connected to the shell base 15.

[0058] Therefore, when the air conditioner is working, the heat exchange plate 16 allows the air conditioning fluid to flow through, and under the action of the fan motor 2, the heat exchange plate 16 is quickly heat-exchanged with the air in the heat exchange duct 11 to cool down or heat up, and the heat exchange efficiency is higher.
