DESCRIPTION OF EMBODIMENTS

[0019] The invention will be further described below by associating drawings with specific embodiments. In the following description, more details are described to sufficiently understand the invention. However, the invention can also be implemented by many other aspects different from those in the description, and it will be apparent that a person skilled in the art can make similar enlargements and deductions in accordance with actual application circumstances without departing from the content of the invention. Consequently, the scope of protection of the invention should not be limited by the content of the specific embodiments.

[0020] FIG. 1 shows an exploded three-dimensional view of a compressor cover 10 in a preferred embodiment of the invention. The compressor cover 10 is applicable to an air treatment unit (not shown in the drawings). The air treatment unit usually has a casing. The compressor cover 10 is provided inside the casing of the air treatment unit. The compressor cover 10 encloses the inside space thereof. A compressor 40 of the air treatment unit is placed in the inside space of the compressor cover 10. The space between the compressor cover 10 and the casing of the air treatment unit is used to house other parts of the air treatment unit, such as a heat exchanger, a fan, and an electrical control box, for example.

[0021] In relation to an air treatment unit installed outdoors, the compressor cover 10 is ideally configured to prevent rainwater from getting in.

[0022] As shown in FIG. 1, the compressor cover 10 of the invention includes side panels 17, 18, 19 and head covers 15, 16. The side panels 17, 18, 19 can be provided upright on a bottom portion of the casing of the air treatment unit. Alternatively, an independent compressor cover bottom plate 20 that supports the compressor 40 may also be provided to stand the side panels 17, 18, 19 upright. As shown in FIG. 2, when the upper edges of the side panels 17, 18, 19 and the side edges of the head covers 15, 16 are interconnected, the entire compressor cover 10 forms a housing space for the compressor 40. The size of the housing space is determined in accordance with the volume of the compressor 40 to be contained therein.

[0023] In particular, the head covers 15, 16 of the compressor cover 10 in this embodiment are particularly configured to have a distributive structure that guides water from the head covers 15, 16 to the side edges of the head covers 15, 16. That is, the head covers 15, 16 are configured by inclined plates that are disposed so as to be inclined with respect to a horizontal plane. The inclined plates are formed with the distributive structure, so that when water reaches the head covers 15, 16 of the compressor cover 10, the water can be guided to the side edges of the head covers 15, 16. For this reason, the formation of water puddles on the head covers 15, 16 can be avoided, and a situation where puddled water gets inside the compressor cover 10 can be effectively avoided. Furthermore, to realize a more effective seal, downwardly bent portions 25, 26 are provided on the head covers 15, 16. When the head covers 15, 16 are attached to the side panels 17, 18, 19, the downwardly bent portions 25, 26 of the head covers 15, 16 cover the upper edges of the side panels 17, 18, 19 from the outside.

[0024] Hereinafter, the structure of the head cover part of the compressor cover 10 will be described in detail with reference to FIG. 1 and FIG. 2.

[0025] According to the preferred embodiment of the invention, the head covers 15, 16 are configured by two inclined plates-a first inclined plate 15 and a second inclined plate 16-that are inclined with respect to a horizontal plane. The first inclined plate 15 and the second inclined plate 16 are disposed in postures in which their angles of inclination α1 and α2 with respect to the horizontal plane are angles between 3 to 10 degrees, and these two inclined plates 15, 16 are inclined in different directions with respect to the horizontal plane. It will be understood from FIG. 4 that the joint line of the first inclined plate 15 and the second inclined plate 16 forms the highest point of the head cover. A pipe passing hole 50 is provided in the head covers 15, 16 to allow them to conform to a pipe member 41 of the compressor 40. The pipe passing hole 50 is provided in the position of a joint line 27 of the two inclined plates 15, 16. In other words, the joint line 27 of the two inclined plates 15, 16 extends through the pipe passing hole 50. A stopper piece 30 for sealing the space between the pipe member 41 of the compressor 40 and the pipe passing hole 50 is provided in the pipe passing hole 50. The stopper piece 30 is manufactured using a flexible sealing material such as at least one of rubber, resin, and silica gel, for example. As shown in FIG. 2, the stopper piece 30 is joined to the first inclined plate 15 and the second inclined plate 16. A sealing groove may also be formed in the stopper piece 30. A reliable seal is formed as a result of the edge of the pipe passing hole 50, which is formed by putting together the inclined plates 15, 16, mating with the sealing groove of the stopper piece 30. It is preferred that when the stopper piece 30 adapts to the pipe passing hole 50 in the inclined plates 15, 16, the top surface of the stopper piece 30 be a little higher than the side edges of the inclined plates 15, 16. By ensuring this, water on the top surface of the stopper piece 30 easily flows to the side edges, so water puddling in the position of the stopper piece 30 is avoided, and even if the air treatment unit is directly left in an open-air environment, the potential for water to get inside the compressor cover 10 is greatly reduced.

[0026] The structures of the side panels 17, 18, 19 of the compressor cover 10 in the preferred embodiment are clearly viewed from FIG. 1. The side panels 17, 18, 19 in this embodiment are disposed substantially perpendicular to a horizontal plane. The side panels 17, 18, 19 are configured by five side surface portions, so that the compressor cover 10 has a five-sided shape when viewed from an overhead direction. To make attachment easier, the five side surface portions are configured by the three side panels 17, 18, 19, and three side surface portions of these are connected to each other to form an integrated folded plate 19. The side surface portion in the middle of the folded plate 19 is connected at obtuse angles to the side surface portions on both ends of the folded plate 19, and the two independent side panels 17, 18 are each connected at right angles as one to the side surface portions of the folded plate 19 with which they are continuous. The compressor 40 has a substantially cylindrical casing, and the arrangement of the side panels 17, 18, 19 of the compressor cover 10 contributes to maximizing space utilization inside the air treatment unit and makes it convenient to attach and detach the compressor cover 10. Ribs may also be provided on the folded plate 19 to improve the strength of the folded plate 19.

[0027] Furthermore, a handle 28 is provided in a side panel to make it easier to detach the compressor cover 10 and inspect and perform maintenance on the compressor 40 inside. Preferably, the handle 28 is provided in the side panel 18 of the two independent side panels 17, 18 to make it easier to first remove the side panel 18 when detaching the compressor cover 10. To maintain the waterproofing effect of the compressor cover 10, the handle 28 is attached to the side panel 18 using a sealing structure that water does not penetrate.

[0028] It is preferred that the compressor 40 be supported by the independent bottom plate 20. FIG. 3 is a three-dimensional view of the bottom plate 20 of the compressor cover. The bottom plate 20 of the compressor cover forms a single space with the bottom plate 20, the side panels 17, 18, 19, and the head covers 15, 16. A compressor anchoring portion 22 for anchoring and connecting the compressor 40 is provided in the bottom plate 20. Furthermore, water discharge holes 23 are also provided in the bottom plate 20. It is preferred that the plural water discharge holes 23 be disposed on different sides around the compressor 40, so as to remove water inside the compressor cover 10 out from the compressor cover 10.

[0029] In a case where the compressor 40 is directly attached to the bottom portion of the casing of the air treatment unit, that part of the bottom portion of the casing doubles as a bottom plate that supports the compressor 40. Additionally, water discharge holes are also provided in that part of the bottom portion of the casing.

[0030] Furthermore, a noise-controlling layer and/or a waterproofing layer may also be adhered to the sides of the side panels 17, 18, 19 and/or the head covers 15, 16 of the compressor cover 10 that face the inside of the compressor cover 10. Furthermore, nonwoven fabric may also be adhered to the sides of the side panels 17, 18, 19 and/or the head covers 15, 16 that face the inside of the compressor cover 10. It is preferred that the noise-controlling layer and the waterproofing layer be adhered to the entire inside surfaces of the side panels 17, 18, 19 and the head covers 15, 16. In a case where the stopper piece 30 has a sealing groove, the noise-controlling layer and/or the waterproofing layer adhered to the inclined plates 15, 16 may also be configured to mate with the sealing groove of the stopper piece 30 together with the head covers 15, 16.

[0031] FIG. 5, FIG. 6, and FIG. 7 show a compressor cover 100 in another embodiment of the invention, the compressor cover 100 includes side panels 117, 118, 119 and a head cover 115, and these are put together to form an inside space. A compressor 140 is contained in this inside space. In this embodiment, the head cover 115 can be formed by an integrated structure resulting from a single plate. It will be understood from FIG. 7 that the head cover 115 is configured by an inclined plate that is inclined with respect to a horizontal plane and has no holes. It is preferred that the angle of inclination of the head cover 115 with respect to the horizontal plane be set between 3 to 10 degrees. With this kind of head cover 115, water flows along the direction of inclination from the head cover, and water puddling on top of the head cover can be avoided.

[0032] In the present embodiment, pipe passing holes 150 are provided in the side panel 117. It is preferred that the pipe passing holes 150 be provided in positions in the upper edge of the side panel 117 adjacent to the head cover 115. Stopper pieces 130 for sealing spaces between pipe members 141 of the compressor 140 and the pipe passing holes 150 are attached to the pipe passing holes 150. The stopper pieces 130 can be manufactured using a flexible sealing material. As shown in FIG. 7, the pipe passing holes 150 are provided in the side panel 117 that is on a side with an inclined edge of the head cover 115.

[0033] The side panels 117, 118, 119 in this embodiment are disposed substantially perpendicular to a horizontal plane. The side panels 117, 118, 119 are configured by five side surface portions, so that the compressor cover has a five-sided shape when viewed from an overhead direction. To make attachment easier, the five side surface portions are configured by the three side panels 117, 118, 119, and three side surface portions of these are connected to each other to form an integrated folded plate 119. The side surface portion in the middle of the folded plate 119 is connected at obtuse angles to the side surface portions on both ends of the folded plate 119, and the two independent side panels 117, 118 are each connected at right angles as one to the side surface portions of the folded plate 119 with which they are continuous. The compressor 140 has a substantially cylindrical casing, and the arrangement of the side panels 117, 118, 119 of the compressor cover 100 contributes to maximizing space utilization inside the air treatment unit and makes it convenient to attach and detach the compressor cover 100. In the present embodiment, the pipe passing holes 150 are provided in the independent side panel 117 that forms a side surface portion on its own.

[0034] When the compressor cover pertaining to the invention is used in an air treatment unit, water puddling on the head cover of the compressor cover is effectively avoided, and water is prevented from getting inside the compressor cover. Furthermore, the installment and combined structure of the side panels and the head cover are convenient to detach.

[0035] Furthermore, by covering the main bodies of the compressors 40, 140 with a soundproofing material, a certain waterproofing effect is fulfilled.
