DETAILED DESCRIPTION OF EMBODIMENTS

[0021] The embodiments will be described in detail below, and examples are shown in the accompanying drawings, in which the same or similar reference numerals refer to the same or similar elements or the elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be illustrative, but should not be construed as limiting the present embodiments.

[0022] A combination of a roof top air conditioning unit according to the present embodiments will be described below with reference to the accompanying drawings.

[0023] FIG. 1 shows an exploded view of the partial structure of an exemplary embodiment of the combination of a roof top air conditioning unit. The partial structure of the combination of a roof top air conditioning unit comprises a base pan 1 of a roof top unit, a base pan air outlet 2, a groove 3 surrounding the base pan air outlet 2, a first connection air duct 4, a second connection air duct 5, a third connection air duct 6, a roof 7 having an opening 8, and an air inlet upper duct 9 of an air distribution box, wherein the third connection air duct 6 is additionally provided with a structure, at the lower portion thereof, fitting the shape of the upper portion of the air inlet upper duct 9. The base pan 1 is disposed on the outer wall of the roof 7, wherein the base pan air outlet 2 is aligned with the opening 8 of the roof, and the air inlet upper duct 9 is provided on an inner wall of the roof 7, wherein the upper portion of the air inlet upper duct 9 is aligned with the opening 8 of the roof; the lower portion of the third connection air duct 6 is adapted and connected to the upper portion of the air inlet upper duct 9; and the upper portion of the third connection air duct 6 is stacked with the second connection air duct 5, the second connection air duct 5 is stacked with the first connection air duct 4, and the first connection air duct 4 is at least partially accommodated in the groove 3, so as to form the perspective view of the partial structure of the combination of a roof top air conditioning unit according to the present embodiment shown in FIG. 3.

[0024] FIG. 2 shows the cross-sectional view of the partial structure, i.e., a connecting structure, of an exemplary embodiment of the combination of a roof top air conditioning unit according to the present embodiment. In this exemplary embodiment, the combination is in a service environment in which the thickness of the roof 7 (FIG. 1) is 23 mm, wherein the depth of the groove 3 may be 14 mm, and the thickness of the connection air ducts (the EPP connection air ducts) 4, 5 and 6 may be 10 mm. As shown in FIG. 2, after the third connection air duct 6 is connected to the second connection air duct 5, there will be a roof thickness gap of 3 mm which is less than the thickness of a single connection air duct (10 mm). However, since a groove with a depth of 14 mm is provided around the base pan air outlet, the gap of 3 mm can be adjusted, that is, one connection air duct (i.e., the first. connection air duct 4) can be further accommodated (i.e., connected) through the groove 3, so as to achieve the connection of the combination of a roof top air conditioning unit, by means of the three connection air ducts, in the case of use of a roof with a thickness between the thickness of the two connection air ducts and the thickness of the three connection air ducts. Furthermore, as shown in FIG. 2, although a gap 10 is provided between the first connection air duct 4 and the groove 3 in a direction substantially perpendicular to the base pan of a roof top unit due to the presence of the groove 3, the first connection air duct can still form a substantially airtight connection with the groove, since the first connection air duct 4 is at least partially accommodated in the groove 3.

[0025] It can be seen that the groove 3, according to the present embodiments, can at least partially accommodate the first connection air duct to adjust the gap that is formed when the roof thickness is not an integral multiple of the thickness of the connection air duct, that is, when the roof thickness is a thickness value between the thickness of n connection air ducts and the thickness of n+1 connection air ducts, it is possible to achieve the connection of the combination of a roof top air conditioning unit, by means of connecting n+1 connection air ducts, through the adjustment of the depth of the groove 3 (which is greater than or equal to the thickness of one connection air duct) on the thickness, without compressing foam sponge to adjust the thickness gap generated when using n connection air ducts, thereby simplifying the complexity of assembly such that the mounting process is simpler and thus the cost is reduced.

[0026] The embodiments shown in the above accompanying drawings and described above are only exemplary. For the service environments with different roof thicknesses, different numbers of connection air ducts should be used, for example, when the thickness is larger, more connection air ducts can be used. Moreover, it should be understood that, in the case where the depth of the groove is greater than or equal to the thickness of the connection air duct, the depth of the groove and the thickness of the connection air duct can use any value in the respective ranges mentioned above, or alternatively, can use the dimension values outside the above ranges.

[0027] In addition, in the combination according to the present embodiments, the roof may be the roof of a vehicle including, but not limited to, a recreation vehicle, a truck or a bus. Additionally or alternatively, the roof may also be the roof of a cruise ship, a ship or a train.

[0028] In the description of the present embodiments, it should be noted that the orientations or position relationship indicated by the terms such as “upper”, “lower”, “inner” and “outer” are based on the orientations or position relationship shown in the accompanying drawings, which is only for ease of description of the present utility model and for simplifying the description, rather than indicating or implying that devices or elements referred to necessarily have a specific orientation structure or operation, and therefore cannot be construed as limiting the present utility model.

[0029] Furthermore, the terms “first”, “second” and “third” are merely used for the illustrative purpose, and should not be construed as indicating or implying the relative importance, Therefore, the features defined with “first”, “second” and “third” can explicitly or implicitly comprise one or more of the features.

[0030] Although the embodiments have been shown and described above, it should be understood that the embodiments described above are merely exemplary and should not be construed as limiting, and those of ordinary skill in the art would have made changes, modifications, replacements and variations to the embodiments described above within the scope of the present disclosure.
