[0041] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0042] The duct unit provided in this embodiment is intended to at least to some extent solve the technical problem that the duct unit is difficult to carry and install.

[0043] Figure 1 It is a schematic diagram of the structure of the air duct machine of some embodiments; Figure 2 for Figure 1 Exploded diagram of . Figure 1 and Figure 2 The duct machine of the embodiment of the present application includes: a heat exchange assembly 10 and a fan assembly 20.

The fan component 201 is detachably connected to the heat exchange assembly 10, and the return air box 202 is detachably connected to the heat exchange assembly 10 and is covered on the fan component 201.

[0044] Duct air conditioners are usually installed on the roof of a house. When installing a duct air conditioner, the duct air conditioner needs to be moved from the ground to the roof of the house. However, the duct air conditioner is large in size and heavy in weight. It requires four to five people to carry and install it, which is not convenient for carrying and installing. In addition, the labor cost is high. It may even be impossible to install the duct air conditioner due to the restrictions of the installation scene. In the prior art, in order to facilitate the transportation and installation of the duct air conditioner, the duct air conditioner is generally miniaturized as a whole. However, when facing a large area of ​​space, the power of the miniaturized duct air conditioner may not meet the needs of the user, affecting the user experience.

[0045] Since the fan assembly 20 includes a fan component 201 and a return air box 202, the fan component 201 is detachably connected to the heat exchange component 10, and the return air box 202 is detachably connected to the heat exchange component 10 and is covered on the fan component 201, so when the duct machine is to be installed, the heat exchange component 10, the fan component 201 and the return air box 202 can be carried separately, and the volume and weight of the heat exchange component 10, the fan component 201 and the return air box 202 are reduced compared to the duct machine, which is convenient for the heat exchange component 1 0. The fan component 201 and the return air box body 202 are carried to the installation location to avoid the difficulty of carrying in a small space. When the heat exchange component 10, the fan component 201 and the return air box body 202 arrive at the installation, the fan component 201 can be installed on the heat exchange component 10, and then the return air box body 202 can be installed on the heat exchange component 10, and then the return air box body 202 can be covered on the fan component 201 to complete the installation of the duct machine, which is convenient for the installation of the heat exchange component 10, the fan component 201 and the return air box body 202, and improves the assembly efficiency.

[0046] When the duct air conditioner is to be assembled, one installer can lift the heat exchange assembly 10, the fan component 201 and the return air box 202 in turn inside the house, and one installer can receive the heat exchange assembly 10, the fan component 201 and the return air box 202 in turn on the roof of the house. Only two installers are needed to install the duct air conditioner, reducing labor costs.

[0047] Figure 3 for Figure 1 Exploded view of the heat exchange components of the medium-pressure tube machine. Figure 3 In some embodiments, in order to facilitate the installation of the fan component 201 , a limiting member 30 is provided on the heat exchange assembly 10 , and the limiting member 30 can conflict with the fan component 201 .

[0048] In some embodiments, when the fan component 201 is to be installed on the heat exchange assembly 10, after the fan component 201 is fitted onto the heat exchange assembly 10, the fan component 201 can be pushed on the heat exchange assembly 10 until the fan component 201 conflicts with the limiting member 30, so as to limit the fan component 201 and ensure that the position of the fan component 201 is determined, so as to facilitate the installation of the fan component 201 on the heat exchange assembly 10.

[0049] Combination Figure 2 In some embodiments, in order to facilitate the installation of the fan component 201, the heat exchange assembly 10 is provided with a first positioning member 40, and the fan component 201 is provided with a second positioning member, and the first positioning member 40 can cooperate with the second positioning member.

[0050] In some embodiments, when the fan component 201 is to be installed on the heat exchange assembly 10, the first positioning member 40 is matched with the second positioning member to achieve positioning of the fan component 201, ensuring that the position of the fan component 201 is determined, so as to facilitate the installation of the fan component 201 on the heat exchange assembly 10. At the same time, when the first positioning member 40 is matched with the second positioning member, the heat exchange assembly 10 can carry the fan component 201, and the installer does not need to hold the fan component 201, which saves manpower and further facilitates the fastening of the fan component 201 to the heat exchange assembly 10.

[0051] In some embodiments, one of the first positioning member 40 and the second positioning member may be a buckle, and the other may be provided with a slot, and the buckle may be locked in the slot to achieve positioning of the fan component 201 on the heat exchange assembly 10.

[0052] In some embodiments, the first positioning member 40 may be a buckle, the second positioning member may be provided with a slot, and the buckle may be locked in the slot. Of course, in other embodiments, the second positioning member may be a buckle, the first positioning member 40 may be provided with a slot, and the buckle may be locked in the slot.

[0053] Combination Figure 2 and Figure 3 In some embodiments, in order to facilitate the installation of the fan component 201, the heat exchange component 10 is provided with a first air outlet 101, a stopper 30 and a first positioning member 40 are provided on the heat exchange component 10, and the fan component 201 is provided with a second positioning member matched with the first positioning member 40. The stopper 30 is located in the first direction of the first air outlet 101, and the first positioning member 40 is located in the second direction of the first air outlet 101, wherein the first direction is arranged at an angle to the second direction, and the angle between the first direction and the second direction may be an acute angle, a right angle, or an obtuse angle.

[0054] In some embodiments, when the fan component 201 is to be installed on the heat exchange assembly 10, after the fan component 201 is fitted onto the heat exchange assembly 10, the fan component 201 can be pushed on the heat exchange assembly 10 until the fan component 201 conflicts with the limiting member 30 to limit the fan component 201 in the first direction of the first air outlet 101. At the same time, the first positioning member 40 is matched with the second positioning member to position the fan component 201 in the second direction of the first air outlet 101, thereby ensuring that the position of the fan component 201 is determined, so as to facilitate the installation of the fan component 201 on the heat exchange assembly 10.

[0055] In some embodiments, the limiting member 30 and the first positioning member 40 cooperate with the second positioning member to achieve limiting and positioning of the fan component 201 from the first direction and the second direction of the first air outlet 101. The fan component 201 is limited and positioned from two different directions to ensure that the position of the fan component 201 is determined, so as to facilitate the installation of the fan component 201 on the heat exchange component 10.

[0056] In some embodiments, the fan component 201 is provided with a second air port 2011, which is connected to the first air port 101, so that the wind of the fan component 201 can enter the heat exchange component 10 through the second air port 2011 and the first air port 101. The limiting member 30 and the first positioning member 40 cooperate with the second positioning member to limit and position the fan component 201 from the first direction and the second direction of the first air port 101, so that the second air port 2011 can be opposite to and connected to the first air port 101, ensuring that the wind of the fan component 201 can smoothly enter the heat exchange component 10 through the second air port 2011 and the first air port 101.

[0057] Combination Figure 2 and Figure 3 In some embodiments, in order to facilitate the installation of the fan component 201, the projected area of ​​the fan component 201 on the heat exchange component 10 is larger than the opening area of ​​the first air outlet 101, so that the fan component 201 has sufficient connection space with the heat exchange component 10, so that the fan component 201 can be fully connected to the heat exchange component 10, and at the same time, it is also convenient to install the fan component 201 on the heat exchange component 10.

[0058] In some embodiments, in order to facilitate the installation of the fan component 201, the stopper 30 is located at the highest point of the first air outlet 101. When the heat exchange assembly 10 is in the installation condition, the stopper 30 is located at the highest point of the first air outlet 101.

[0059] In some embodiments, since the duct air conditioner is generally suspended or placed flat on the ceiling, when the fan component 201 is to be installed on the heat exchange assembly 10, the fan component 201 needs to be pushed upward until the fan component 201 conflicts with the limit member 30 to achieve the limitation of the fan component 201. At the same time, the rough positioning of the fan component 201 is also achieved to facilitate the installation of the fan component 201.

[0060] In some embodiments, in order to facilitate the installation of the fan component 201 , the first air outlet 101 is polygonal, and the limiting member 30 is located at the longest side of the first air outlet 101 .

[0061] In some embodiments, in order to ensure the air volume and to avoid the duct machine from occupying too much height space, the first air outlet 101 is rectangular, and the limiter 30 is located at the longest side of the first air outlet 101. The length of the limiter 30 can match the longest side of the first air outlet 101. When the fan component 201 conflicts with the limiter 30, the contact area between the fan component 201 and the limiter 30 can be guaranteed, so as to ensure the stability of the limiter 30 limiting the fan component 201, so as to further facilitate the installation of the fan component 201.

[0062] In some embodiments, the limiting member 30 may be a folded edge at the first air outlet 101 to reduce manufacturing costs and improve the structural strength of the heat exchange assembly 10 .
