Description

Technical Field

[0001] The present invention relates to a snow protection roof attached to an outdoor unit of an air conditioner (also referred to as an outdoor unit for air conditioning), and to a snow protection roof that can be attached to outdoor units of various specifications with a small number of parts.

Background Art

[0002] Snow protection devices may be used in combination with the outdoor unit of an air conditioner to protect the outdoor unit from snow damage. The outdoor unit takes in air through an air intake provided on the back and exhausts air through an exhaust port provided on the front to perform heat exchange. However, if the front or back of the outdoor unit is covered with snow, the air flow will stop and heat exchange will not be possible. Snow protection for the outdoor unit is important not only on the front side but also on the back side. Compared with the front side where there is a large space and it is difficult for snow to accumulate, on the back side, the building wall is adjacent, and snow is likely to accumulate in the gap between the back of the outdoor unit and the building wall.

[0003] For example, Patent Document 1 discloses a snow protection device in which a slidable roof is further provided on a roof installed for snow protection. The installation conditions of outdoor units vary individually, and the distances from the back of the outdoor unit to the building wall are also various. The slidable roof can adjust the sliding amount according to the distance to the adjacent building wall. Therefore, the slidable roof can block the gap between the back of the outdoor unit and the building wall and prevent snow accumulation on the back side of the outdoor unit.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, the snow prevention device described in Patent Document 1 cannot accommodate an outdoor unit that is larger than the accommodation space of the snow prevention device because the entire outdoor unit is accommodated inside the snow prevention device with a roof. Further, even when accommodating an outdoor unit that is smaller than the accommodation space of the snow prevention device described in Patent Document 1, it is necessary to secure an installation space of that size. Furthermore, in the snow prevention device described in Patent Document 1, since the entire outdoor unit is to be accommodated, a base for placing the outdoor unit and a pillar for covering the entire outdoor unit are required, resulting in a problem of a large number of parts and an increase in manufacturing cost.

[0006] The present invention has been made in view of the above problems, and provides a snow prevention roof that can be installed on outdoor units of various specifications, does not require an installation space wider than the installation space of the outdoor unit, and can be manufactured with a small number of parts.

Means for Solving the Problems

[0007] The snow prevention roof of the present invention includes a top plate that covers the upper part of the outdoor unit for air conditioning, a support plate that supports the top plate in a state of being inclined forward with respect to the front direction of the outdoor unit for air conditioning, a slide top plate that is slidably connected to the top plate, and a portal-shaped connecting plate in which a plurality of pairs of long holes are formed vertically on the left and right, and is characterized in that it is fixed to the outdoor unit for air conditioning by fastening the outdoor unit and the connecting plate using the long holes that match the screw holes of the outdoor unit.

Embodiments for Carrying Out the Invention

[0010] Hereinafter, the snow-proof roof of the present invention will be described based on each embodiment with reference to the drawings. Note that the drawings schematically show the snow-proof roof, the constituent members of the snow-proof roof, and the peripheral members of the snow-proof roof, and the dimensions and dimensional ratios on the drawings do not necessarily match the actual dimensions and dimensional ratios. Also, unless otherwise specified, for convenience, the directions such as up and down are represented based on the orientation of the snow-proof roof shown in FIG. 1. Redundant explanations will be omitted as appropriate, and the same reference numerals may be given to the same members.

[0011] (First Embodiment) Fig. 1 shows a snow-proof roof 100 according to an embodiment of the present invention, and Fig. 5 shows an exploded view of the snow-proof roof 100 to be mounted on the upper part of the outdoor unit 1. The outdoor unit 1 is installed adjacent to a building wall surface (not shown). Generally, the distance between the rear surface 1b of the outdoor unit 1 and the building wall surface is usually about several tens of centimeters. The outdoor unit 1 performs heat exchange by taking in air from an air intake port (not shown) provided on the rear surface 1b and exhausting the air from an exhaust port 2 provided on the front surface 1a. However, as described above, since the distance between the rear surface 1b and the building wall surface is usually about several tens of centimeters, snow is likely to accumulate. If the space between the rear surface 1b of the outdoor unit 1 and the building wall surface is filled with accumulated snow, the intake of air from the air intake port provided on the rear surface 1b will be obstructed, and the outdoor unit 1 will be unable to perform heat exchange.

[0012] Fig. 2 shows an exploded front view of the snow-proof roof in the first embodiment of the present invention. As shown in Fig. 2, the snow-proof roof 100 includes a top plate 3 that covers the upper part of the outdoor unit 1, and a support plate 5 that supports the top plate 3 on the upper surface 1e of the outdoor unit 1 (see Fig. 4). The support plate 5 supports the top plate 3 in a state of inclining downward from the rear surface 1b side to the front surface 1a side of the outdoor unit 1 (see Fig. 3).

[0013] The top plate 3 is provided with a rectangular top plate portion 3a that covers the upper part of the outdoor unit 1, a front portion 3b bent at a substantially right angle from the front end of the top plate portion 3a, a rear portion 3c bent at a substantially right angle from the rear end of the top plate portion 3a, a right side surface portion 3d bent at a substantially right angle from the right end of the top plate portion 3a, and a left side surface portion 3e bent at a substantially right angle from the left end of the top plate portion 3a. The top plate portion 3a is formed larger than the upper surface 1e of the outdoor unit 1 in a plan view, preventing snow from accumulating on the outdoor unit 1. Two long holes 3f are formed in the front portion 3b in the longitudinal direction. Similarly, two long holes 3f are formed in the rear portion 3c in the longitudinal direction. Two screw holes 3g are formed in the right side surface portion 3d. Similarly, two screw holes 3g are formed in the left side surface portion 3e (see Fig. 4).

[0014] In this embodiment, a steel plate is used as the material of the top plate 3. By using a steel plate, the front part 3b, the back part 3c, etc. can be easily formed by bending. Also, since the steel plate has high strength, even a thin plate can be threaded such as the threaded hole 3g. Note that the material of the top plate 3 is not particularly limited, and light metals such as aluminum can also be used. Also, it is possible to use a resin material by changing dimensions such as the thickness of the top plate 3.

[0015] As shown in FIGS. 3 and 4, the support plate 5 is provided with an inclined portion 5a that inclines from the back surface 1b side to the front surface 1a side of the outdoor unit 1 so as to approach the upper surface 1e of the outdoor unit 1, a threaded hole 5b formed at the front end surface of the inclined portion 5a, a threaded hole 5c formed at the back end surface of the inclined portion 5a, a threaded hole 5d formed on the side surface of the support plate 5, and a bottom portion 5e facing the upper surface 1e of the outdoor unit 1.

[0016] The top plate 3 and the support plate 5 are fixed using bolts 5f. The support plate 5 supports the inclined portion 5a in contact with the back surface of the top plate portion 3a. In a state where the support plate 5 supports the top plate 3, the front part 3b covers the threaded hole 5b of the support plate 5. A long hole 3f is formed in the front part 3b, and the front part 3b is fixed to the front end of the support plate 5 by the bolt 5f passing through the long hole 3f and being fastened to the threaded hole 5b. Similarly, in a state where the support plate 5 supports the top plate 3, the back part 3c covers the threaded hole 5c of the support plate 5. A long hole 3f is formed in the back part 3c, and the back part 3c is fixed to the rear end of the support plate 5 by the bolt 5f passing through the long hole 3f and being fastened to the threaded hole 5c. Here, since the bolt 5f is detachable, by loosening the bolt 5f, the support plate 5 can move in the left - right direction by the length of the long hole 3f with respect to the top plate 3. When the lateral width of the outdoor unit 1 is short, the interval between the two support plates 5 becomes short, and when the lateral width of the outdoor unit 1 is long, the interval between the two support plates 5 becomes long. Thus, the snow - proof roof 100 according to this embodiment can be attached to outdoor units 1 of various sizes.

[0017] A slide top plate 6 is connected to the top plate 3 so as to overlap the upper surface of the top plate portion 3a. The slide top plate 6 is provided with a rectangular top plate portion 6a similar to the top plate portion 3a of the top plate 3, and a pair of a right guide portion 6b and a left guide portion 6c that sandwich the right side surface portion 3d and the left side surface portion 3e of the top plate 3. Both the top plate portion 3a and the top plate portion 6a are formed in a planar shape. The right side surface portion 3d and the right guide portion 6b are arranged parallel to each other. A slight gap is secured between the right side surface portion 3d and the right guide portion 6b in a state where the slide top plate 6 is placed so as to overlap the top plate 3. Similarly, the left side surface portion 3e and the left guide portion 6c are arranged parallel to each other. A slight gap is secured between the left side surface portion 3e and the left guide portion 6c in a state where the slide top plate 6 is placed so as to overlap the top plate 3. Thus, since a gap is secured between the slide top plate 6 and the top plate 3, the slide top plate 6 can slide on the top plate 3.

[0018] As described above, two screw holes 3g are formed in the right side surface 3d of the top plate 3. Similarly, two screw holes 3g are also formed in the left side surface 3e of the top plate 3 (not shown). Bolts 6e are used to fix the top plate 3 and the slide top plate 6. As described above, the right guide portion 6b and the left guide portion 6c sandwich the right side surface 3d and the left side surface 3e of the top plate 3. Therefore, each screw hole 3g is covered by the right guide portion 6b and the left guide portion 6c. Long hole-shaped slide holes 6d are formed in the right guide portion 6b and the left guide portion 6c, respectively. The right guide portion 6b is fixed by the bolt 6e passing through the slide hole 6d and being fastened to the screw hole 3g of the right side surface 3d. Similarly, the left guide portion 6c is fixed by the bolt 6e passing through the slide hole 6d (not shown) of the left side surface 3e and being fastened to the screw hole 3g. Here, by loosening the bolt 6e, the slide top plate 6 can slide relative to the top plate 3 in the inclined direction by the length of the slide hole 6d. The installation conditions of the outdoor unit 1 vary individually, and the distances from the back surface of the outdoor unit 1 to the building wall surface are also various. However, since the slide top plate 6 can slide relative to the top plate 3, it is possible to close the gap from the back surface 1b of the outdoor unit 1 to the building wall surface according to the change, and prevent snow accumulation on the back side of the outdoor unit.

[0019] As shown in FIG. 7, a rectangular deformation portion 10 is provided at the end of the right side surface 3d of the top plate 3. The deformation portion 10 described below is similarly formed at the end of the left side surface 3e of the top plate 3. The deformation portion 10 has a notch 10a formed near the boundary line between the top plate portion 3a and the right side surface 3d, a notch 10b formed near the boundary line between the right side surface 3d and the back surface 3c, an outer edge portion 10c, and a bending portion 10d where the right side surface 3d bends. The notch 10a is formed parallel to the boundary line between the top plate portion 3a and the right side surface 3d starting from the boundary between the back surface 3c and the right side surface 3d. The notch 10a extends in the front surface 3b direction from the two screw holes 3g provided. Also, the notch 10a is cut out with a predetermined thickness in the longitudinal direction of the right side surface 3d, and the notch 10a separates the right side surface 3d and the top plate portion 3a.

[0020] The notch 10b is formed parallel to the boundary line between the right side surface portion 3d and the back surface portion 3c starting from the boundary between the top plate portion 3a and the right side surface portion 3d. The notch 10b extends to the outer edge portion 10c of the right side surface portion 3d. Also, the notch 10b is notched with a predetermined thickness in the short side direction of the right side surface portion 3d. Therefore, the notch 10b separates the right side surface portion 3d and the back surface portion 3c. For this reason, the rectangular deformation portion 10 is separated from any member at the three sides of the notch 10a, the notch 10b, and the outer edge portion 10c. Only the bent portion 10d of the deformation portion 10 is connected to another member.

[0021] As shown in FIG. 5, bolts 6e are used to fix the top plate 3 and the slide top plate 6. The slide top plate 6 is fixed to the top plate 3 by the bolts 6e passing through the slide holes 6d and being fastened to the screw holes 3g of the right side surface portion 3d. As described above, a slight gap is secured between the right side surface portion 3d and the right guide portion 6b. Thin steel plates are used for the top plate 3 and the slide top plate 6. Therefore, when the bolts 6e are tightened, either the right side surface portion 3d or the right guide portion 6b will deform by the amount of this gap. When the right guide portion 6b deforms, the influence reaches up to the top plate portion 6a, and the top plate portion 6a is distorted, greatly damaging the aesthetics. However, the right side surface portion 3d is provided with a deformation portion 10. The rectangular deformation portion 10 is separated from any member at the three sides of the notch 10a, the notch 10b, and the outer edge portion 10c. For this reason, the force due to the tightening of the bolts 6e easily concentrates on the bent portion 10d, and it easily bends toward the right guide portion 6b. By the bending of the bent portion 10d, the deformation of the top plate portion 6a can be prevented. Since the bent portion 10d is covered by the slide top plate 6 when the snow-proof roof 100 is in use, even if it deforms, the aesthetics are not impaired.

[0022] As shown in Fig. 4, the snow-proof roof 100 is provided with a connecting plate 7 that connects the support plate 5 and the outdoor unit 1, and fixing bolts 7d. The connecting plate 7 is a plate-shaped component with a portal shape when viewed from the front. As shown in Fig. 6, the connecting plate 7 has rectangular legs 7a on both sides, a cross beam 7b connecting the upper parts of the respective legs 7a, and a load receiving portion 7c protruding from the cross beam 7b in a substantially right-angled direction.

[0023] Long holes 8 for fixing to the outdoor unit 1 are formed in the two legs 7a respectively. The connecting plate 7 is fixed to the outdoor unit 1 by removing an existing bolt (not shown) of the outdoor unit 1 and re-fastening the removed bolt through the long hole 8 to an existing screw hole of the outdoor unit 1. A long hole 9 for fixing the support plate 5 is formed in the cross beam 7b. The support plate 5 is fixed to the connecting plate 7 by fastening the bolt 7d through the long hole 9 to the screw hole 5d of the support plate 5.

[0024] The long hole 8 is formed long in the horizontal direction when the connecting plate 7 is viewed from the front. Therefore, when the connecting plate 7 is fixed to the right side surface 1c and the left side surface 1d of the outdoor unit 1, the long hole 8 is arranged to extend long in the front-rear direction from the front surface 1a to the back surface 1b of the outdoor unit 1. The long holes 8 are formed in pairs in the two legs 7a. When the long holes 8 are used for fixing to the outdoor unit 1, for example, a pair of long holes 8a and 8a' are used. The intervals between the existing screw holes on the right side surface 1c and the left side surface 1d of the outdoor unit 1 vary depending on the model number etc. of the outdoor unit 1. However, as described above, the long hole 8 is formed to extend long in the front-rear direction from the front surface 1a to the back surface 1b of the outdoor unit 1. Therefore, it can correspond to various existing screw positions.

[0025] Furthermore, a plurality of elongated holes 8 are formed in pairs in the vertical direction (perpendicular direction) of the left and right leg portions 7a. When fixing to the outdoor unit 1, an elongated hole that matches the position may be selected from among the plurality of elongated holes 8 formed in pairs in the vertical direction. The load receiving portion 7c formed on the connecting plate 7 preferably contacts the upper surface 1e when fixing to the outdoor unit 1. This is because when the load receiving portion 7c contacts the upper surface 1e, the weight of the snow-proof roof 100 and the accumulated snow can be received by the load receiving portion 7c, preventing deformation of the connecting plate 7. On the other hand, the distances from the upper surface 1e of the outdoor unit 1 to the existing screw holes on the right side surface 1c and the left side surface 1d of the outdoor unit 1 vary depending on the model number and the like. Therefore, when the load receiving portion 7c is arranged to contact the upper surface 1e, if only a pair of elongated holes 8 are formed, there may be a case where the elongated holes 8 cannot correspond to the arrangement positions of the existing screw holes. However, as described above, by forming a plurality of pairs of elongated holes 8 in the vertical direction of the two leg portions 7a, an elongated hole 8 that corresponds to the position of the existing screw hole can be selected. For example, normally, elongated holes 8b and 8b' are used. When the distance from the upper surface 1e of the outdoor unit 1 to the existing screw hole is short, elongated holes 8a and 8a' may be used. When the distance from the upper surface 1e of the outdoor unit 1 to the existing screw hole is long, elongated holes 8c and 8c' may be used. Thus, since the connecting plate 7 has a plurality of pairs of elongated holes 8, an appropriate combination of elongated holes 8 can be selected from among the plurality of elongated holes 8 and fixed to the existing screw holes of the outdoor unit 1.

[0026] The long hole 9 is formed horizontally long in the cross beam 7b of the connecting plate 7. Therefore, when the connecting plate 7 is fixed to the side surface of the outdoor unit 1, the long hole 9 is arranged to extend long in the front-rear direction from the front surface 1a to the back surface 1b of the outdoor unit 1. The long hole 9 is formed in the cross beam 7b. The support plate 5 is fixed to the connecting plate 7 by the bolt 7d passing through the long holes 9a and 9a' and being fastened to the screw hole 5d of the support plate 5. Since the bolt 7d is detachable, by loosening the bolt 7d, the support plate 5 can move in the front-rear direction with respect to the outdoor unit 1 by the length of the long hole 9. The installation situation of the outdoor unit 1 varies. When the distance between the back surface 1b of the outdoor unit 1 and the building wall surface is wide, there may be a gap between the wall surface even when the slide top plate 6 is extended to the maximum. In this case, by moving the support plate 5 to the back surface 1b side of the outdoor unit 1, the slide top plate 6 can be brought into contact with the building wall surface.

[0027] In this way, since the snow-proof roof 100 allows the top plate 3 and the support plate 5 to be directly connected to the outdoor unit 1 using the connecting plate 7, a frame for accommodating the outdoor unit 1 and a foundation for installing the outdoor unit 1 are not required. It can be attached to any size of outdoor unit 1, does not require an installation space wider than the installation space of the outdoor unit 1, and can be manufactured with a small number of parts.

[0028] Next, the usage method of the snow-proof roof 100 will be described. Remove the existing bolts (not shown) at the upper parts of the right side surface 1c and the left side surface 1d of the outdoor unit 1 to expose the existing screw holes (not shown). Pass the removed existing bolts through any two of the plurality of long holes 8 of the connecting plate 7 and fasten them to the existing screw holes to fix the connecting plate 7 to the outdoor unit 1. At this time, the long holes 8b and 8b' may be used. When the distance from the upper surface 1e of the outdoor unit 1 to the existing screw holes is short, the long holes 8a and 8a' may be used. Also, when the distance from the upper surface 1e of the outdoor unit 1 to the existing screw holes is long, the long holes 8c and 8c' may be used. Next, fix the support plate 5 to the connecting plate 7 fixed to the outdoor unit 1 using two bolts 7d. Then, fix the top plate 3 to the support plate 5. For the fixation, use four bolts 5f and adjust the position so that the top plate 3 is located at the center of the outdoor unit 1. Place the slide top plate 6 on the top plate portion 3a of the top plate 3 so as to overlap. The placed slide top plate 6 is first temporarily fixed to the top plate 3 using four bolts 6e. Finally, slide the temporarily fixed slide top plate 6 and adjust the position so that it contacts the wall surface of the adjacent building. After the adjustment, fasten the four temporarily fixed bolts 6e to the screw holes 3g. If the slide top plate 6 does not contact the wall surface even when slid to the maximum, loosen the bolts 7d and move the support plate 5 to the back surface 1b side of the outdoor unit 1, and adjust again so that the slide top plate 6 contacts the wall surface.

[0029] (Second Embodiment) FIG. 8 shows a connecting plate 11 according to the second embodiment of the present invention. This connecting plate 11 is different from the connecting plate 7 according to the first embodiment in the points described below, and in other points, it has the same configuration as the connecting plate 7 according to the first embodiment.

[0030] As shown in Fig. 8, the connecting plate 11 of this embodiment has rectangular legs 11a on both sides and a cross beam 11b connecting the upper parts of the respective legs 11a. Long holes 12 used for fixing to the outdoor unit 1 are formed in the two legs 11a respectively. The connecting plate 11 is fixed to the outdoor unit 1 by removing an existing bolt (not shown) of the outdoor unit 1 and re-fastening the removed bolt through the long hole 12 to the existing screw hole of the outdoor unit 1. A long hole 13 used for fixing the support plate 5 is formed in the cross beam 11b. The support plate 5 is fixed to the connecting plate 11 by fastening a bolt 7d through the long hole 13 to the screw hole 5d of the support plate 5.

[0031] The long hole 12 for fixing the connecting plate 11 to the outdoor unit 1 is formed long in the horizontal direction in the front view of the connecting plate 11. Therefore, when the connecting plate 11 is fixed to the right side surface 1c and the left side surface 1d of the outdoor unit 1, the long hole 12 is arranged to extend long in the front-rear direction from the front surface 1a to the back surface 1b of the outdoor unit 1. The long holes 12 are formed in the two legs 11a in pairs on the left and right. When the long hole 12 is used for fixing to the outdoor unit 1, a pair of long holes 12a and 12a' are used. The intervals between the existing screw holes on the right side surface 1c and the left side surface 1d of the outdoor unit 1 vary depending on the model number etc. of the outdoor unit 1. However, as described above, the long hole 12 is arranged to extend long in the front-rear direction from the front surface 1a to the back surface 1b of the outdoor unit 1. Therefore, it can correspond to various arrangement positions of the existing screw holes.

[0032] The elongated holes 13 for fixing the support plate 5 to the connecting plate 11 are formed longitudinally long in the cross beam 11b of the connecting plate 11. Therefore, when the connecting plate 11 is fixed to the side surface of the outdoor unit 1, the elongated holes 13 are arranged so as to extend further upward from the upper surface 1e of the outdoor unit 1. The elongated holes 13 are formed in pairs in the left - right direction in the cross beam 11b. When the elongated holes 13 are used for fixing the support plate 5, for example, a pair of elongated holes 13a and 13a' are used. The support plate 5 is fixed to the connecting plate 7 by bolts 7d passing through the elongated holes 13a and 13a' and being fastened to the screw holes 5d of the support plate 5. Here, it is preferable that the bottom 5e of the support plate 5 is in contact with the upper surface 1e when fixed to the outdoor unit 1. This is because when the bottom 5e is in contact with the upper surface 1e, the weight of the snow - proof roof 100 and the accumulated snow can be received by the bottom 5e, preventing deformation of the connecting plate 11. However, the distances from the upper surface 1e of the outdoor unit 1 to the existing screw holes on the right side surface 1c and the left side surface 1d of the outdoor unit 1 vary depending on the model number and the like. Therefore, when the bottom 5e of the support plate 5 is arranged to be in contact with the upper surface 1e, if the elongated holes 13 are formed horizontally long in the front view of the connecting plate 11, there is a possibility that the elongated holes 13 may not correspond to the arrangement positions of the screw holes 5d of the support plate 5. However, as described above, the elongated holes 13 are formed longitudinally long in the cross beam 11b of the connecting plate 11. Therefore, it is possible to correspond to the arrangement positions of the screw holes 5d of the support plate 5 without being affected by the arrangement positions of the existing screw holes. In this way, by using the elongated holes 13 formed longitudinally long in the cross beam 11b of the connecting plate 11 for fixing the support plate 5, the bottom 5e of the support plate 5 can be arranged to be in contact with the upper surface 1e of the outdoor unit 1.

[0033] Furthermore, a plurality of elongated holes 13 are formed in pairs in the left - right direction of the cross beam 11b. When using the elongated holes 13 for fixing to the support plate 5, an optimal combination can be selected from among the plurality of elongated holes 13 formed in pairs in the left - right direction. For example, when it is desired to fix the support plate 5 to the center of the outdoor unit 1, the elongated holes 13b and 13b' can be used. Here, the installation situation of the outdoor unit varies individually, and the distance from the back surface of the outdoor unit to the building wall surface also varies. There may be a case where even when the slide top plate 6 is slid to the maximum, the slide top plate 6 does not contact the wall surface. In such a case, the elongated holes 13c and 13c' can be used. By using the elongated holes 13c and 13c', the support plate 5 can be moved to the back surface 1b side of the outdoor unit 1 and readjusted so that the slide top plate 6 contacts the wall surface. Thus, since the connecting plate 11 has a plurality of elongated holes 13 formed longitudinally long in the cross beam 11b of the connecting plate 11, an optimal combination of the elongated holes 13 can be selected from among the plurality of elongated holes 13 to fix the support plate 5.
