[0002] At present, air conditioner duct machines are widely used in central air conditioning systems or corridor air conditioning systems, and can also be used in household air conditioning systems.

[0003] The existing duct machine installation methods can be divided into horizontal installation and vertical installation, and can also be divided into exposed installation and concealed installation. Users can select appropriate installation methods according to use requirements and actual installation space. When the duct machine is installed under different working conditions, the installation level of the duct machine should be ensured to achieve the best use state. If the duct machine is not installed horizontally, the use effect of the duct machine will be reduced, and even the service life of the duct machine will be affected. In the traditional duct machine installation process, the installation workers generally use detection tools to detect the levelness of the duct machine, and then correct and level. However, under different working conditions, the installation of the duct machine is limited by different installation methods and installation spaces, so that the detection error of the traditional detection tool is large, and even the levelness detection cannot be performed, thereby causing the duct machine to be installed horizontally.

[0037] The preferred embodiments of the present application will be described below with reference to the accompanying drawings, in which: The skilled in the art should understand that these embodiments are only used to explain the technical principles of the present application, and are not intended to limit the protection scope of the present application.

[0038] It should be noted that in the description of the present application, the terms "inner", "outer", "upper", "lower", "top", "bottom" and the like indicating the direction or positional relationship are based on the direction or positional relationship shown in the drawings, which is only for the convenience of description, and does not indicate or imply that the device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application. In addition, the terms "first", "second", "third", "fourth" are only for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0039] In addition, it should also be noted that in the description of the present application, unless otherwise explicitly specified and limited, the terms "provided", "connected", "mounted" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrally connected. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0040] Based on the problem of the existing pipeline machine that the levelness detection is inconvenient under different working conditions, the present application provides a water pan, a heat exchange assembly and a pipeline machine, which aims to judge the level state of the pipeline machine by setting a detection point in the water pan and a level detection port communicated with the water pan, so that the levelness of the pipeline machine installation can be detected without professional detection tools, meeting the installation needs of the pipeline machine under different working conditions, and making the installation and leveling of the pipeline machine more simple and convenient.

[0041] Specifically, first refer to Figure 1 , Figure 1 is a structural schematic diagram of the pipeline machine of the present application.

[0042] As Figure 1 shown, the present application provides a pipeline machine, the pipeline machine of the present application comprises a shell 1 and a heat exchange assembly installed in the shell 1, the heat exchange assembly of the present application comprises a heat exchanger 2 and a water pan 3, and the heat exchanger 2 is installed above the water pan 3.

[0043] During the working process of the pipeline machine, condensate water will be generated on the heat exchanger 2, the condensate water drops into the water pan 3 below the heat exchanger 2, and then is discharged through the drain port 5 on the water pan 3.

[0044] Next refer to Figure 2 and Figure 3 , among them, Figure 2 is a structural schematic diagram of the water pan of the present application. Figure 1 , Figure 3 is a structural schematic diagram of the water pan of the present application. Figure 2 .

[0045] As Figure 3 andFigure 2 As shown in the drawings, the water pan 3 of the present application has a water collecting groove 31 and a level detection opening 4 communicating with the water collecting groove 31, the water collecting groove 31 has a detection point, and the lowest end of the level detection opening 4 is at the same level as the detection point.

[0046] Exemplarily, as shown in the drawings, Figure 3 and Figure 2 As shown in the drawings, the water pan 3 of the present application is rectangular, the water collecting groove 31 is a closed groove arranged along the circumference of the water pan 3, the water collecting groove 31 is arranged along the side wall of the water pan 3, that is, the water collecting groove 31 shares a side wall with the water pan 3, the outer side wall of the water collecting groove 31 is provided with the level detection opening 4, the water collecting groove 31 is provided with the detection point, and the lowest end of the level detection opening 4 is at the same level as the detection point. After the installation of the pipe machine is completed, water is poured into the water collecting groove 31. Since the lowest end of the level detection opening 4 is at the same level as the detection point, when the water in the water collecting groove 31 rises to the detection point, it just flows out from the level detection opening 4, which indicates that the pipe machine is installed in a horizontal state. If the water in the water collecting groove 31 rises to the detection point but no water flows out from the level detection opening 4, or the water in the water collecting groove 31 has not risen to the detection point but water has already flowed out from the level detection opening 4, it indicates that the pipe machine is not installed horizontally and needs to be re-installed and corrected. Therefore, without professional detection tools, the levelness of the installation of the pipe machine can be detected, the installation and leveling of the pipe machine are more simple and convenient, and the installation requirements of the pipe machine under different working conditions are met.

[0047] It should be noted that the shape of the water pan 3 is not limited in the present application. For example, the water pan 3 can also be circular, and the like.

The water collecting groove 31 can also be arranged on the inner side of the outer wall of the water pan 3, and the like. Such adjustment and change of the specific position and shape of the water collecting groove 31 do not deviate from the principles and scope of the present application and should be limited within the protection scope of the present application.

[0059] It should be noted that the present application does not limit the setting positions of the lowest point 316 of the bottom surface of the water collecting groove 31 and the highest point 315 of the bottom surface of the water collecting groove 31. For example, the lowest point 316 of the bottom surface of the water collecting groove 31 can be set at any position of the bottom surface of the water collecting groove 31, or the highest point 315 of the bottom surface of the water collecting groove 31 can be set at any position away from the lowest point 316 of the bottom surface of the water collecting groove 31, as long as the bottom surface of the water collecting groove 31 is inclined downward from the highest point 315 to the lowest point 316.
