[0033] The duct machine provided in the embodiment of the present application is as follows: Figure 1 and Figure 2 As shown, it includes a housing 600 and an integrated component, and the integrated component is arranged in the housing 600. Figures 1 to 7 As shown, the integrated assembly includes an air outlet frame assembly and a heat exchanger assembly 100, and the heat exchanger assembly 100 is located on the side of the air outlet frame assembly facing the inside of the housing 600. The air outlet frame assembly includes: an air outlet bracket 200, and the air outlet bracket 200 is provided with a first air outlet 211 and a first mounting portion 230. In the first direction, the first mounting portion 230 is located on the first side of the first air outlet 211 (the first side of the first air outlet 211 faces the inside of the housing 600), and in the second direction, the first mounting portion 230 and the first air outlet 211 are arranged in sequence. In the first direction, the heat exchanger assembly 100 is located on the first side of the first air outlet 211 and is fixed to the first mounting portion 230.

In this solution, the air outlet bracket 200 is configured as a plastic part, so that the first mounting portion 230 can be easily designed as a plug-in connection portion, a positioning portion, a snap-on connection portion and a screw connection portion, etc. In this solution, the fixing method of the heat exchanger component 100 and the air outlet bracket 200 is simpler; moreover, after the heat exchanger component 100 and the air outlet bracket 200 are assembled into an integrated component, the integrated component is installed as a whole in the shell 600, which can reduce the difficulty of assembling the heat exchanger component 100 and the air outlet bracket 200 in the shell 600.

[0035] In some examples, such as Figure 2 , Figure 3 , Figure 4 and Figure 6As shown, the air outlet frame assembly also includes a rotary drive member 300 and a switch door 400. The air outlet bracket 200 is also provided with an inspection port 213 and a second mounting portion 240. The first air outlet 211 and the inspection port 213 are sequentially arranged in the second direction. In the first direction, the second mounting portion 240 is located at the first side of the inspection port 213 and is arranged to fix the rotary drive member 300. The first air outlet 211 is arranged to install a swingable switch door 400. The rotary drive member 300 is arranged opposite to the inspection port 213 and is used to drive the switch door 400 to swing. The rotary drive member 300 drives the switch door 400 to swing, so that the switch door 400 opens and closes the first air outlet 211. When the rotary drive member 300 fails, the rotary drive member 300 can be disassembled and repaired from the inspection port 213, so that the disassembly and repair process of the rotary drive member 300 is simpler.

[0036] The second mounting portion 240, the rotary drive member 300 and the switch door 400 may be provided as a group; or the second mounting portion 240, the rotary drive member 300 and the switch door 400 may be provided as a group; Figures 2 to 4 As shown, the second mounting portion 240, the rotating drive member 300 and the switch door 400 are arranged in two groups, and the two switch doors 400 are arranged in sequence in the up-down direction, and open and close the first air vent 211 together; or the second mounting portion 240, the rotating drive member 300 and the switch door 400 are arranged in three groups, and the three switch doors 400 are arranged in sequence in the up-down direction, and open and close the first air vent 211 together; the inspection port 213 may include one and is arranged on the left side of the first air vent 211; or the inspection port 213 may include one and is arranged on the right side of the first air vent 211; or the inspection port 213 may include two and are arranged on the left and right sides of the first air vent 211, etc.; all of the above can achieve the purpose of the present application, and its purpose does not deviate from the design concept of the present invention, and will not be repeated here, and all should belong to the protection scope of the present application.

[0037] In some embodiments, Figure 4As shown, the air duct machine also includes a water receiving tray 500, which is arranged in the housing 600 and at the lower side of the heat exchanger assembly 100. A second air outlet 510 is arranged at the front of the water receiving tray 500, and the second air outlet 510 is located at the lower rear side of the first air outlet 211. The rotary drive member 300 drives the switch door 400 to swing, and the switch door 400 can also open and close the second air outlet 510. That is, the switch door 400 can open the first air outlet 211 and the second air outlet 510 at the same time to achieve the first air outlet 211 and the second air outlet 510 to discharge air at the same time, and the switch door 400 can also selectively open the first air outlet 211 and the second air outlet 510 to achieve the first air outlet 211 and the second air outlet 510 to selectively discharge air. It can be that, when heating, the switch door 400 opens the second air vent and closes the first air vent 211, so that the hot air is blown downward from the second air vent, so that the hot air falls to the ground quickly; it can be that, when cooling, the switch door 400 closes the second air vent and opens the first air vent 211, so that the cold air is blown forward from the first air vent 211, so that the cold air is prevented from blowing directly on people; or it can be that, when cooling, the switch door 400 first opens the first air vent 211 and the second air vent at the same time, and after a set time, the switch door 400 closes the second air vent and opens the first air vent 211. When the first air vent 211 is opened, cold air will first blow into the room from the first air vent 211 and the second air vent at the same time, thereby achieving rapid cooling of the room. After a set time, the cold air will be blown forward from the first air vent 211 again, thereby preventing the cold air from blowing directly on people. Alternatively, the user may control the opening and closing of the door 400 as needed, such as opening the second air vent and closing the first air vent 211 during cooling. All of the above can achieve the purpose of the present application, and the purpose does not deviate from the design concept of the present invention, and will not be repeated here, and should all fall within the protection scope of the present application.

[0038] In other embodiments, Figure 8 and Fig. 9As shown, the air outlet bracket 200 is further provided with a second air outlet 280, and in the first direction, the second air outlet 280 is located at the first side of the first air outlet 211, and in the third direction, the second air outlet 280 is located at the fifth side (i.e., the lower side) of the first air outlet 211, and in this solution, the second air outlet 280 is located on the air outlet bracket 200, and the first air outlet 211 discharges air toward the front side, and the second air outlet 280 discharges air toward the lower side. Among them, the third direction is the up-down direction, and the fifth side is the lower side. Furthermore, the rotary drive member 300 drives the switch door 400 to swing, and the switch door 400 can also open and close the second air outlet 280. That is, the switch door 400 can open the first air vent 211 and the second air vent 280 at the same time to achieve simultaneous air discharge from the first air vent 211 and the second air vent 280, or the switch door 400 can selectively open the first air vent 211 and the second air vent 280 to achieve selective air discharge from the first air vent 211 and the second air vent 280. It can be that when heating, the switch door 400 opens the second air vent 280 and closes the first air vent 211, so that the hot air is blown downward from the second air vent 280, so that the hot air falls to the ground quickly; it can be that when cooling, the switch door 400 closes the second air vent 280 and opens the first air vent 211, so that the cold air is blown forward from the first air vent 211, so that the cold air is prevented from blowing directly on people; or it can be that when cooling, the switch door 400 first opens the first air vent 211 and the second air vent 280 at the same time, and after a set time, the switch door 400 closes the second air vent 280. When the first air vent 280 is opened and the first air vent 211 is opened, cold air will first blow into the room from the first air vent 211 and the second air vent 280 at the same time, so as to realize rapid cooling of the room. After the set time, the cold air will be blown forward from the first air vent 211 again, so as to prevent the cold air from blowing directly on people. Alternatively, the user can control the opening and closing of the door 400 according to the needs, such as opening the second air vent 280 and closing the first air vent 211 during cooling. All of the above can achieve the purpose of the present application, and its purpose does not deviate from the design concept of the present invention, and will not be repeated here, and should all fall within the protection scope of the present application.

[0039] In some examples, the first air outlet 211 is provided with a plurality of hinged portions 212 at intervals in the third direction, and the plurality of switch doors 400 are connected to the plurality of hinged portions 212 in a one-to-one correspondence. Figure 4 and Figure 7As shown, the multiple groups of hinged parts 212 include two groups of hinged parts 212, and the two groups of hinged parts 212 are located at both ends of the first air outlet 211 in the third direction. The second mounting parts 240 include two, and the two second mounting parts 240 correspond to the two groups of hinged parts 212 one by one. The two groups of hinged parts 212 are configured to hinge and connect the two switch doors 400, and each group of hinged parts 212 includes a plurality of hinged parts 212 arranged at intervals (such as evenly distributed) in the left and right directions, so that the switch doors 400 can be better supported and local bending and deformation of the switch doors 400 can be avoided. The two switch doors 400 are configured to open and close the first air outlet 211 at the same time, and the switch door 400 located at the lower part is configured to open and close the second air outlet 510. The size of the first air vent 211 in the vertical direction is greater than the size of the second air vent 510 in the front-to-back direction; when the two switch doors 400 close the first air vent 211, the size of the switch door 400 located at the lower part in the vertical direction is greater than the size of the switch door 400 located at the upper part in the vertical direction, and the upper end of the switch door 400 located at the upper part and the lower end of the switch door 400 located at the lower part are hingedly connected to the two sets of hinge parts 212 in a one-to-one correspondence. In order to avoid air leakage at the hinged position, sealing sponges are provided between the hinged ends of the two switch doors 400 in the vertical direction and the mouth wall of the first air vent 211 for sealing.

[0040] It can be that the switch door 400 located at the upper part has a first position and a second position, and the switch door 400 located at the lower part has a third position, a fourth position and a fifth position. Figure 2 As shown, the upper switch door 400 is in the second position, and the lower switch door 400 is in the fourth position, then the two switch doors 400 together close the first air vent 211, and the lower switch door 400 opens the second air vent 510; Figure 4 As shown, when the upper switch door 400 is in the first position and the lower switch door 400 is in the third position, the two switch doors 400 jointly open the first air vent 211, and the lower switch door 400 closes the second air vent 510; when the upper switch door 400 is in the first position and the lower switch door 400 is in the fifth position (the fifth position is between the third position and the fourth position), the two switch doors 400 jointly open the first air vent 211, and the lower switch door 400 opens the second air vent 510.

[0041] In some examples, such as Figure 2 , Figure 4 and Figure 7As shown, the mouth wall of the first air outlet 211 is provided with a first annular mating surface 250, and in the first direction, the first annular mating surface 250 faces the first side (the first side, i.e., the rear side) of the first air outlet 211, and the first annular mating surface 250 is configured to cooperate with the two switch doors 400 to close the first air outlet 211. At this time, the adjacent ends of the two switch doors 400 are sealed and abutted by overlapping (a sealing sponge can be added here to improve the sealing effect during overlapping), so that when the second air outlet 510 discharges cold air, air leakage occurs at the first air outlet 211, resulting in condensation water and whistling sounds; moreover, when only the second air outlet 510 discharges air, the two switch doors 400 are under the action of the wind pressure formed by the wind beam blown by the shell 600, the overlapping parts of the adjacent ends of the two switch doors 400 are pressed by the wind pressure, and the peripheries of the two switch doors 400 are pressed by the wind pressure against the first annular mating surface 250, so that the two switch doors 400 can better seal the first air outlet 211. Among them, the first air outlet 211 is provided with a reinforcing rib 270 erected along the front-to-back direction, and the shape of the rear end surface of the reinforcing rib 270 matches the shape of the side surfaces of the two switch doors 400. When the switch door 400 located at the upper part is in the second position and the switch door 400 located at the lower part is in the fourth position, the front side surfaces of the two switch doors 400 abut against the rear end surface of the reinforcing rib 270. The reinforcing rib 270 includes a plurality of reinforcing ribs 270, and the plurality of reinforcing ribs 270 are sequentially arranged at intervals in the left-right direction, so that the structural strength of the integrated component can be better improved. The hinged portion 212 located at the upper part is located at the upper part of the first annular mating surface 250, and the hinged portion 212 located at the lower part is located at the lower part of the first annular mating surface 250.

[0042] In some examples, such as Figure 4 As shown, the wall of the second air vent 510 is provided with a second annular mating surface 260. In the third direction, the second annular mating surface 260 faces the sixth side (i.e., the upper side) of the second air vent 510. The second annular mating surface 260 is configured to cooperate with the switch door 400 located below to close the second air vent 510. This can prevent air leakage at the second air vent 510 and the occurrence of condensation water and whistling sounds when the first air vent 211 discharges cold air. Similarly, when only the first air vent 211 discharges air, the switch door 400 located at the bottom is pressed against the second annular mating surface 260 by the wind pressure formed by the wind beam blown from the inside of the housing 600. In this way, the switch door 400 located at the bottom has a better effect of closing the second air vent 510.

[0043] It can be that the first mounting portion 230 includes a group and is disposed on the left side of the rear portion of the first air outlet 211; or it can be that the first mounting portion 230 includes a group and is disposed on the right side of the rear portion of the first air outlet 211; or it can be that Figures 5 to 7As shown, the first mounting part 230 includes two groups, the first air outlet 211 is located between the two groups of first mounting parts 230, and the heat exchanger assembly 100 is fixedly connected to the two first mounting parts 230 one by one at both ends in the left and right directions; the above can all achieve the purpose of this application, and its purpose does not deviate from the design concept of the present invention, and will not be repeated here, and should all fall within the protection scope of this application.

[0044] In some examples, such as Figures 5 to 7 As shown, each set of first mounting portions 230 includes at least one of a plug-in connection portion, a positioning portion, a snap-on connection portion, and a screw-on connection portion. Figure 2 , Figure 3 , Figures 5 to 7 As shown, the first mounting portion 230 includes a plug-in connection portion, a positioning portion and a screw connection portion, the plug-in connection portion is configured as an insert rib arranged in the up-and-down direction, the positioning portion is configured as a positioning groove, and the screw connection portion is configured as a screw hole, the heat exchanger assembly 100 includes a heat exchanger 110 and two mounting frames 120, the two mounting frames 120 are connected to the two side plates of the heat exchanger 110 in a one-to-one correspondence, each mounting frame 120 is provided with a slot, a positioning protrusion and a through hole, the slot is inserted into the insert rib from bottom to top, the positioning protrusion is inserted into the positioning groove, and the screw passes through the through hole and is screwed into the screw hole, so that when the duct machine is subjected to a drop test, the mounting frame 120 of the heat exchanger assembly 100 will not move relative to the air outlet bracket 100.

[0045] In some examples, such as Figures 3 to 9 As shown, the air outlet bracket 200 includes a first frame plate 210 and a second frame plate 220 connected to form a folded structure. In the first direction, the second frame plate 220 is located at the first side (the first side is the rear side) of the first frame plate 210, and in the third direction, the second frame plate 220 is located at the sixth side (the sixth side is the upper side) of the first frame plate 210.
