Definitions

• the air conditioner 100 is installed, for example, on the ground outdoors, and a rectangular duct connecting member 41 provided around the air outlet 12a is connected to an outlet duct DC (see Figures 6 and 7, described below) that connects the indoor space, which is the space to be air-conditioned, with the outdoors.
• the air conditioner 100 also has a hood 20 fixed to the rear panel 14 of the housing 11 so as to cover the air inlet 14a. By driving the fan 7, the air conditioner 100 draws outdoor air through the air inlet 14a via the hood 20, passes the air through the heat exchanger 30, and exchanges heat with the heat medium inside the heat exchanger 30.
• the heat exchanger 30 is, for example, a fin-and-tube heat exchanger, and is arranged in a V-shape when viewed from the side inside the housing 11. This arrangement is intended to ensure an effective area and reduce the external dimensions of the housing 11, but it also serves as a partition plate that ensures that air always passes through the heat exchanger 30.

• This duct connection member 41 is formed with a second opening 41a that is rectangular in plan view, and an upwardly protruding second standing wall portion 41b is provided around the periphery of the second opening 41a to surround the second opening 41a.
• Four second standing wall portions 41b are provided along the second opening 41a.
• the second standing wall portions 41b prevent rainwater from entering the second opening 41a of the duct connection member 41, which communicates with the air outlet 12a of the top panel 12, and are used to attach the air outlet duct DC.
• the lower end of the second standing wall portion 41b is provided with a flange portion 41c that extends outward. This flange portion 41c is used to attach to the top cover 40.
• Figure 5 is a perspective view illustrating a method for attaching the duct connection member 41 to the air conditioner 100 according to embodiment 1.
• Figure 6 is a perspective view illustrating a method for attaching the outlet duct DC to the air conditioner 100 according to embodiment 1.

• Screw holes are formed at corresponding positions on the flange portion 41c of the duct connection member 41 and on the peripheral portion 40c1 of the first opening 40a of the upper surface portion 40c of the top cover 40.
• the duct connection member 41 is positioned so that the second vertical wall portion 41b surrounds the first vertical wall portion 40b of the top cover 40 from the outside.
• Screws SR are inserted vertically into the screw holes in the flange portion 41c and the peripheral portion 40c1, and the flange portion 41c is fixed to the peripheral portion 40c1 with the screws SR.
• the duct connection member 41 is fixed to the top cover 40 with the screws SR at two locations on each of the four corners and one location in the center of each of the four sides.
• the duct connection member 41 can be attached to the top cover 40 by attaching the screws SR, and can be removed from the top cover 40 by removing the screws SR.
• the duct connection member 41 is detachably attached to the top cover 40.
• the second standing wall portion 41b of the duct connection member 41 is positioned to surround the first standing wall portion 40b of the top cover 40, the first standing wall portion 40b and the second standing wall portion 41b can double-block rainwater, preventing it from entering the interior of the housing 11 through the air outlet 12a.
• the air outlet duct DC is connected to the duct connection member 41 before the duct connection member 41 is attached to the top cover 40.
• a plurality of screw holes are formed at corresponding positions on the lower end of the air outlet duct DC and the second vertical wall portion 41b of the duct connection member 41.
• the air outlet duct DC is then positioned to surround the second vertical wall portion 41b of the duct connection member 41 from the outside, and screws SR are inserted horizontally into the screw holes on the lower end of the air outlet duct DC and the second vertical wall portion 41b, and the air outlet duct DC is fixed to the second vertical wall portion 41b with the screws SR.
• the top cover 40 is positioned to surround the four side surfaces 40d from the outside, and screws SR are inserted horizontally into the screw holes in the rear and left and right side surface surfaces 40d, the rear panel 14, and the pair of side panels 15, thereby fixing the rear and left and right side surface surfaces 40d to the rear panel 14 and the pair of side panels 15, respectively.
• an extension 40e extending inward (toward the rear) is provided at the lower end of the front side surface 40d, and a gap 40f is formed between the extension 40e and the front panel 13.
• the front side surface 40d protrudes forward further than the inner (rear) end of the extension 40e.
• providing the extension 40e makes it more difficult for rainwater to seep into the interior of the housing 11 between the front side surface 40d and the front panel 13. Furthermore, by covering the gap 40f with the infiltration suppression member 43 described above, it is possible to prevent rainwater from infiltrating into the interior of the housing 11 through the gap 40f.
• screws SR are used as fixing members between the housing 11 and the infiltration suppression member 43, between the housing 11 and the top cover 40, between the duct connection member 41 and the top cover 40, and between the duct connection member 41 and the outlet duct DC, but this is not limited to this and other members may be used as long as they are substitutable.
• the top cover 40 has a box shape with no bottom and a lid, and has four side sections 40d that form the front, back, left, and right sides.
• the front side section 40d has an extension section 40e at the lower end that extends to the rear side, and a gap 40f is formed between the extension section 40e and the front surface of the housing 11, and a space 40g is formed between the front side section 40d and the front surface of the housing 11.
• FIG. 11 is an exploded perspective view of the top cover 40 according to the second embodiment.
• FIG. 12 is an oblique view illustrating the watertight structure of the air conditioner 100 according to the second embodiment.
• four first standing wall portions 40b of the top cover 40 are provided along the first opening 40a, at the front, rear, left, and right of the first opening 40a.
• Gaps G are formed between adjacent first standing wall portions 40b, i.e., at the four corners of the first opening 40a, during manufacturing. This is because the first standing wall portions 40b of the top cover 40 are manufactured by bending the periphery of the first opening 40a.
• These key-shaped portions 42a are portions where the joints between the rubber plate pieces of the rubber plate 42 are key-shaped. Therefore, even if water does enter between the peripheral edge 40c1 of the upper surface 40c of the top cover 40 and the flange 41c of the duct connection member 41, the key-shaped portions 42a can block the water, making it difficult for the water to reach the inside of the rubber plate 42. Additionally, the hook-shaped portion 42a prevents gaps from occurring at the joints due to variations in the position of the rubber plate pieces of the rubber plate 42 when they are joined together.
• the first opening 40a has a rectangular shape
• four first standing wall portions 40b are provided along the first opening 40a
• corner reinforcement members 40h are provided at each of the four corners of the first opening 40a to fill the gaps G formed between adjacent first standing wall portions 40b, and the inner surfaces of the corner reinforcement members 40h are welded to the ends of the adjacent first standing wall portions 40b.
• corner reinforcement members 40h are welded to the first vertical wall portions 40b of the top cover 40 to create a watertight structure, which makes it possible to prevent rainwater from entering the first opening 40a that communicates with the air outlet 12a through the gap G between adjacent first vertical wall portions 40b.
• the gap between them can be filled, creating a watertight structure and preventing water from entering the air outlet 12a located inside the rubber plate 42.
• the rubber plate 42 is formed by joining four rectangular rubber plate pieces, and the four corners of the rubber plate 42 are each provided with a key-shaped portion 42a, where the joints between the rubber plate pieces are key-shaped.
• the four corners of the rubber plate 42 are each provided with a key-shaped portion 42a, where the joints between the rubber plate pieces form a key shape. Therefore, even if water seeps in between the peripheral edge 40c1 of the upper surface 40c of the top cover 40 and the flange portion 41c of the duct connecting member 41, the key-shaped portion 42a can block the water, making it difficult for the water to reach the inside of the rubber plate 42.
