It can be understood that when the air duct machine 10 is in a cooling state, the heat exchanger 300 acts as an evaporator to cool the air, so that the air duct machine 10 blows out cold air.

[0040] Reference Figure 3As shown, the duct machine 10 of one embodiment of the present invention further includes a mounting structure 400, which is fixedly connected to the housing 100. The mounting structure 400 can be fixed to a corresponding position inside the housing 100 by screwing, clamping or welding, so as to facilitate the installation of the filter 200 and the heat exchanger 300. Specifically, the mounting structure 400 is formed with a first mounting groove 410 and a second mounting groove 420, and at least one end of the first mounting groove 410 is provided with a first introduction port 411, and the filter 200 slides into the first mounting groove 410 through the first introduction port 411, so that the filter 200 is positioned and installed in the first mounting groove 410. It can be understood that the first introduction port 411 can be set at one end of the first mounting groove 410, so that the filter 200 can be installed or removed from the corresponding end; the first introduction port 411 can also be respectively set at both ends of the first mounting groove 410, so that the filter 200 can be installed or removed from both ends. In addition, at least one end of the second mounting groove 420 is provided with a second introduction port 421, and the heat exchanger 300 slides into the second mounting groove 420 through the second introduction port 421, so that the heat exchanger 300 is positioned and installed in the second mounting groove 420. It can be understood that the second introduction port 421 can be set at one end of the second mounting groove 420, so that the heat exchanger 300 can be installed or removed from the corresponding end; the second introduction port 421 can also be respectively set at both ends of the second mounting groove 420, so that the heat exchanger 300 can be installed or removed from both ends. This embodiment improves the installation efficiency of the filter 200 and the heat exchanger 300, and is convenient for later repair and maintenance; and the first mounting groove 410 and the second mounting groove 420 are integrated on the mounting structure 400 and fixedly connected to the housing 100, which has a compact structure and is easy to install, which is conducive to reducing the overall size of the air duct machine 10 and reducing the manufacturing cost.

[0041] It should be noted that, refer to Figure 1 and Figure 2 As shown, a mounting opening 110 is provided at one or both ends of the casing 100 in the left-right direction, a first mounting groove 410 and a second mounting groove 420 extend in the left-right direction, and a first inlet 411 and a second inlet 421 are arranged on the same side of the casing 100 as the mounting opening 110, so that the filter 200 and the heat exchanger 300 can be installed in the mounting structure 400 through the mounting opening 110, which is convenient for installation and disassembly, further improving the installation efficiency of the filter 200 and the heat exchanger 300, and also improving the efficiency of subsequent repair and maintenance.

[0042] Further, see Figure 1 and Figure 2As shown, in some embodiments of the present invention, two mounting structures 400 are provided, and the two mounting structures 400 are respectively provided at the upper and lower ends of the housing 100. It can be understood that two first mounting grooves 410 are also provided and are respectively arranged in the housing 100 along the up and down directions, so that the two first mounting grooves 410 are used together to position and install the filter 200, and its positioning is more stable and not easy to get loose; in addition, two second mounting grooves 420 are also provided and are arranged in the housing 100 along the up and down directions, so that the two second mounting grooves 420 are used together to position and install the heat exchanger 300, and its positioning is more stable and not easy to get loose.

[0043] Reference Figure 3 and Figure 4 As shown, in some embodiments of the present invention, the mounting structure 400 also includes a pressure strip 430, which is arranged in the first mounting groove 410 to press the filter 200. The pressure strip 430 has a certain elasticity and can be compatible with the installation of filter screens 200 with similar height dimensions, thereby avoiding the disadvantage that the existing mounting structure 400 can only be applied to filter screens 200 of one size. Specifically, the mounting structure 400 of this embodiment can adapt to the height dimension of the filter screen 200. The range of variation is 1 / 2 to 1 / 3 of the height of the pressure strip 430, thereby improving versatility. Specifically, the pressure strip 430 can be symmetrically arranged in the middle of the two first mounting grooves 410, respectively, so that the filter screen 200 can be installed in the center, thereby improving the stability of the installation of the filter screen 200.

[0044] Reference Figure 3 and Figure 4 As shown, in some embodiments of the present invention, one end of the pressure strip 430 facing the first introduction port 411 is a fixed end 431, and the other end is a free end 432.

This structure can make the pressure strip 430 stably connected to the first installation groove 410, and when the filter screen 200 is introduced from the first introduction port 411, it will not interfere with the pressure strip 430, and ensure that the pressure strip 430 is always in contact with the filter screen 200 to achieve positioning installation.

[0045] Reference Figure 3As shown, in some embodiments of the present invention, the pressure strip 430 is formed with a matching surface 433 that abuts against the filter 200, and the matching surface 433 can be a plane, an arc surface or a spherical surface, etc., to apply a force to the filter 200. It can be understood that when the matching surface 433 is designed to be a plane, the plane structure makes the contact area between the filter 200 and the pressure strip 430 larger, increases the friction between the two, and improves the connection stability between the filter 200 and the first installation groove 410.

[0046] Reference Figure 3 and Figure 4 As shown, in some embodiments of the present invention, at least one side of the second inlet 421 along the front-to-back direction is formed with an inlet slope 422, which facilitates the heat exchanger 300 to slide in and install from the second inlet 421, or slide out and remove, thereby improving the efficiency of installation and removal of the heat exchanger 300.

The U-shaped plate includes a third connecting edge 451, a fourth connecting edge 452, and a bottom plate 453 connected between the third connecting edge 451 and the fourth connecting edge 452, and the bottom plate 453 is fixedly connected to the first plate 440, so that the first plate 440 and the second plate 450 are stably connected to form the mounting structure 400, the third connecting edge 451 and the first connecting edge 441 form a first mounting groove 410, and the fourth connecting edge 452 and the second connecting edge 442 form a second mounting groove 420. The mounting structure 400 formed by the fixed connection of the first plate 440 and the second plate 450 in this embodiment has a stable structure, convenient assembly, and low living cost. It should be noted that the connection method of the first plate 440 and the second plate 450 can be screw connection, riveting, welding, etc., which is not specifically limited here.
