Summary of the Invention

Problems to be Solved by the Invention

[0004] The above integrated air conditioner does not consider the situation of installation in a space where a ventilation device is not installed, or the situation where it cannot be installed near the ventilation device due to restrictions such as space. In such a situation, for example, it is necessary to exhaust the air discharged from the outdoor exhaust port to a space different from the space where the integrated air conditioner is installed.

Mode for Carrying Out the Invention

[0019] [1. Embodiment] Hereinafter, with reference to the drawings, an integrated air conditioner according to an embodiment of the present invention will be described. FIG. 1 is a perspective view of an integrated air conditioner 10 according to an embodiment.

[0020] The integrated air conditioner 10 is configured to be able to exhaust into a space (hereinafter referred to as the "exhaust space") different from the space (hereinafter referred to as the "installation space") where the integrated air conditioner 10 is installed without using a ventilation device installed in, for example, a kitchen or the like. The integrated air conditioner 10 includes a main body 20, an exhaust duct 30, and an exhaust attachment 40 (hereinafter referred to as the "attachment 40").

[0021] The main body 20 has a known configuration disclosed in, for example, Patent Document 1 or the like. The main body 20 has a case 21. Inside the case 21, a heat exchanger or the like (not shown) constituting a refrigeration cycle or a heating cycle is accommodated. An outdoor air intake (not shown) and an outdoor exhaust port 22 are formed in the case 21. The air outside the case 21 is sucked in through the outdoor air intake, heat-exchanged by the refrigeration cycle or the heating cycle, and then discharged from the outdoor exhaust port 22.

[0022] The exhaust duct 30 is through which the air discharged from the outdoor exhaust port 22 passes. The specific configuration of the exhaust duct 30 can be arbitrarily selected as long as it can connect the main body 20 and the attachment 40. In this embodiment, the exhaust duct 30 is, for example, a flexible bellows-shaped duct that can expand and contract within a predetermined range. One end 31 of the exhaust duct 30 is connected to the outdoor exhaust port 22 of the case 21. The other end 32 of the exhaust duct 30 is connected to the attachment 40.

[0023] Figure 2 is a front perspective view of the attachment 40 in Figure 1. Figure 3 is a rear perspective view of the attachment 40 in Figure 1. Figure 4 is a rear view of the attachment 40 in Figure 1. Figure 5 is a front view of the attachment 40 in Figure 1. Figure 6 is a bottom view of the attachment 40 in Figure 1.

[0024] The attachment 40 is configured to be detachably attached to the other end 32 of the exhaust duct 30. The attachment 40 is configured to be sandwiched between opening and closing elements that separate the installation space and the exhaust space. The opening and closing elements can be arbitrarily selected as long as they are capable of sandwiching the attachment 40. The opening and closing elements are, for example, doors. The doors are, for example, sliding doors, suspended doors, or hinged doors. The types of sliding doors and suspended doors are, for example, single-sliding type, double-sliding type, or double-sliding type. The types of hinged doors are, for example, single-leaf type, double-leaf type, or folding door. If the exhaust duct 30 is sandwiched between opening and closing elements, a large gap will be formed between the opening and closing elements. This will reduce the cooling or heating efficiency. The attachment 40 is configured to suppress the reduction in cooling or heating efficiency even when sandwiched between opening and closing elements.

[0025] The materials constituting the attachment 40 can be arbitrarily selected. In this embodiment, the attachment 40 is entirely made of a resin material. The resin material is, for example, acrylonitrile butadiene styrene resin, polypropylene resin, or polyvinyl chloride resin. In this embodiment, the attachment 40 is made of acrylonitrile butadiene styrene resin. The attachment 40 may be partially or entirely made of a metal material. Hereinafter, the left-right direction in a front view of the attachment 40 (see Figure 5) will be referred to as the width direction, the direction perpendicular to the width direction in a front view of the attachment 40 will be referred to as the height direction, and the direction perpendicular to both the width direction and the height direction will be referred to as the depth direction. The height direction coincides with the height direction of the opening and closing element.

[0026] As shown in Figure 2 or Figure 3, the attachment 40 has a connection section 50, an exhaust section 60, and an intermediate section 70. Each element constituting the attachment 40 may be made up of a plurality of divided parts or may be made up as a single unit. In this embodiment, the attachment 40 is made up of a first part 41 and a second part 42 that are symmetrical with respect to the central axis OA in a front view (see Figure 5). In this embodiment, the first part 41 and the second part 42 are each made up as a single unit. The first part 41 constitutes the connection section 50, the exhaust section 60, and the intermediate section 70 on one side with respect to the central axis OA. The second part 42 constitutes the connection section 50, the exhaust section 60, and the intermediate section 70 on the other side with respect to the central axis OA.

[0027] When the attachment 40 is composed of multiple parts, the method of joining each part can be arbitrarily selected. For example, the multiple parts may be joined by interlocking protrusions and indentations, or by adhesive or the like. In this embodiment, the first part 41 and the second part 42 are joined by the interlocking of claw members (not shown) formed on their end faces. In this embodiment, mainly from the viewpoint of aesthetics, protrusions 43 are formed on the attachment 40 where the claw members are located so that the claw members are not visible from the outside. In this embodiment, protrusions 43 are formed in a total of six locations: three on the top of the attachment 40 and three on the bottom.

[0028] As shown in Figure 3 or Figure 4, the connecting portion 50 is formed at one end of the attachment 40 in the depth direction. The connecting portion 50 is a cylindrical portion having a first opening 51 that connects to the exhaust duct 30. The shape of the first opening 51 can be arbitrarily selected as long as it is a shape into which the other end 32 of the exhaust duct 30 can be inserted. In this embodiment, the shape of the first opening 51 is a circle having an inner diameter slightly larger than the outer diameter of the other end 32 of the exhaust duct 30. Multiple wall portions 52 capable of holding the other end 32 of the exhaust duct 30 are formed on the inner surface of the connecting portion 50. The multiple wall portions 52 are shaped to extend in the circumferential direction of the connecting portion 50. Note that the other end 32 of the exhaust duct 30 and the connecting portion 50 may be connected via any member.

[0029] As shown in Figure 2 or Figure 5, the exhaust section 60 is formed at the other end of the attachment 40 in the depth direction. The exhaust section 60 is configured to be sandwiched between opening and closing elements. The exhaust section 60 has a second opening 61 for exhausting air that has passed through the first opening 51 into the exhaust space. The exhaust section 60 is configured such that the area of ​​the gap in the opening and closing elements when the exhaust section 60 is sandwiched between the opening and closing elements is smaller than the area of ​​the gap in the opening and closing elements when the exhaust duct 30 is sandwiched between the opening and closing elements. In other words, the maximum width of the second opening 61 in the width direction is narrower than the maximum width of the first opening 51 in the width direction. The shape of the second opening 61 can be arbitrarily selected. From the viewpoint of reducing the gap formed in the opening and closing elements when the exhaust section 60 is sandwiched between the opening and closing elements, it is preferable that the second opening 61 has a shape that extends in the height direction. In this embodiment, the second opening 61 is a rectangle that extends in the height direction. If the second opening 61 has a shape that extends in the height direction, the width dimension can be made smaller while maintaining the area of ​​the second opening 61. As a result, the area of ​​the gap between the opening and closing elements is minimized.

[0030] The area of ​​the second opening 61 can be arbitrarily selected. From the viewpoint of suppressing a decrease in exhaust efficiency, it is preferable that the area of ​​the second opening 61 is substantially equal to or larger than the area of ​​the first opening 51. In this embodiment, the area of ​​the second opening 61 and the area of ​​the first opening 51 are substantially equal. Therefore, the attachment 40 of this embodiment is configured so as not to make the opening area of ​​the second opening 61 larger than necessary while suppressing a decrease in exhaust efficiency.

[0031] As shown in Figure 5, the exhaust section 60 has a pair of parallel side walls 62 and 63 facing each other in the width direction, an upper wall 64 connecting the upper ends of side walls 62 and 63, and a lower wall 65 connecting the lower ends of side walls 62 and 63. The side walls 62 and 63, the upper wall 64, and the lower wall 65 define the second opening 61. Since the pair of side walls 62 and 63 are parallel in the width direction, it is difficult for a gap to form between the opening / closing element and the pair of side walls 62 and 63. For example, if the pair of side walls 62 and 63 have a tapered shape in which the width in the width direction narrows from the intermediate section 70 toward the second opening 61, a gap will be formed between the pair of side walls 62 and 63 and the opening / closing element. In this embodiment, since the outer surfaces of the pair of side walls 62 and 63 and the opening / closing element are in contact without gaps, a decrease in cooling efficiency or heating efficiency is suppressed.

[0032] As shown in Figure 2 or Figure 3, guides 62A and 63A are formed on the outer surfaces of the side walls 62 and 63 to guide the position of the opening and closing elements. This makes it easy to position the opening and closing elements relative to the exhaust section 60. The guides 62A and 63A define the area of ​​the exhaust section 60 that the opening and closing elements contact. The guides 62A and 63A extend in the height direction on the outer surfaces of the side walls 62 and 63.

[0033] As shown in Figure 5, the exhaust section 60 has a reinforcing section 66 that extends from one inner surface of the side wall 62 to the inner surface of the side wall 63. The reinforcing section 66 connects the inner surface of the side wall 62 and the inner surface of the side wall 63. This increases the strength of the exhaust section 60. The shape of the reinforcing section 66 can be arbitrarily selected as long as it connects the inner surface of the side wall 62 and the inner surface of the side wall 63. In this embodiment, the shape of the reinforcing section 66 is cylindrical. The reinforcing section 66 includes a first reinforcing section 66A, a second reinforcing section 66B, a third reinforcing section 66C, and a fourth reinforcing section 66D. The first reinforcing section 66A and the second reinforcing section 66B extend from the inner surface of the side wall 62 toward the inner surface of the side wall 63. The third reinforcing section 66C and the fourth reinforcing section 66D extend from the inner surface of the side wall 63 toward the inner surface of the side wall 62. The tip of the first reinforcement part 66A and the tip of the third reinforcement part 66C are in contact. The tip of the second reinforcement part 66B and the tip of the fourth reinforcement part 66D are in contact.

[0034] As shown in Figure 2 or Figure 3, the intermediate section 70 connects the connection section 50 and the exhaust section 60. An exhaust passage 70A (see Figure 4 or Figure 5) is formed in the intermediate section 70, connecting the first opening 51 and the second opening 61. The intermediate section 70 has a pair of side walls 71 and 72, an upper wall 73, and a lower wall 74.

[0035] As shown in Figure 6, the pair of side walls 71 and 72 narrow in width as they move from the connection section 50 towards the exhaust section 60. As shown in Figure 3, the upper wall 73 curves upward in the height direction as it moves from the connection section 50 towards the exhaust section 60. The lower wall 74 extends in a generally straight line from the connection section 50 towards the exhaust section 60. Therefore, the exhaust passage 70A is configured to narrow in width as it moves from the connection section 50 towards the exhaust section 60, while increasing in height.

[0036] From the viewpoint of convenience, the attachment 40 is preferably configured to be self-supporting. As shown in Figure 6, the attachment 40 has a mounting section 80 so that it can be easily placed on the floor. The mounting section 80 is composed of the lower surface of the connecting section 50, the lower surface of the lower wall 74 of the intermediate section 70, and the lower surface of the lower wall 65 of the exhaust section 60. The lower surface of the connecting section 50, the lower surface of the lower wall 74 of the intermediate section 70, and the lower surface of the lower wall 65 of the exhaust section 60 constitute a continuous plane 80A.

[0037] As described above, the attachment 40 of this embodiment has multiple protrusions 43 formed on it, mainly from the viewpoint of design. For this reason, from the viewpoint of installing the attachment 40 more stably, it is preferable that at least one of the protrusions 43 formed on the installation portion 80 has an upright portion 81 that extends outward from the protrusion 43 in the width direction. The height of the upright portion 81 from the plane 80A is substantially the same as the height of the protrusion 43 from the plane 80A. In this embodiment, the upright portion 81 is formed only on the protrusion 43 that is closest to the exhaust portion 60 among the protrusions 43 formed on the installation portion 80.

[0038] [2. Features] The width HA shown by the solid line in Figure 7 is the maximum width formed in the opening / closing element when the exhaust section 60 of the attachment 40 is sandwiched between the opening / closing element. The width HB shown by the dashed line in Figure 7 is the maximum width formed in the opening / closing element when the other end 32 of the exhaust duct 30 is sandwiched between the opening / closing element. The attachment 40 is configured such that width HA is narrower than width HB. More specifically, the attachment 40 is configured such that the area of ​​the gap in the opening / closing element when the exhaust section 60 is sandwiched between the opening / closing element is smaller than the area of ​​the gap in the opening / closing element when the exhaust duct 30 is sandwiched between the opening / closing element. Therefore, even when exhausting into the exhaust space, a decrease in cooling efficiency or heating efficiency can be suppressed. For example, if the opening / closing element is a hinged door, comparing the case where the exhaust duct 30 is sandwiched between the hinged door and the case where the attachment 40 is sandwiched between the hinged door, the opening / closing width (gap) of the hinged door can be made smaller when the attachment 40 is sandwiched between the hinged door. Therefore, it is possible to suppress a decrease in cooling or heating efficiency.

[0039] [3.
