Description

Technical Field

[0001] The present invention relates to an anti-vibration mount.

Background Art

[0002] Conventionally, a water heater provided with wall-mounting brackets at the upper and lower parts of the back plate of a housing has been known (see, for example, Patent Document 1). In such a water heater, there has been a problem that vibrations and noises of a fan provided in the housing are directly transmitted to the wall surface through the brackets. In order to solve such a problem, for example, a water heater in which an anti-vibration mount is fixed to the bottom of the housing has been known.

[0003] For example, the anti-vibration mount 200 shown in FIG. 9 includes a cover portion 201 and a mounting table 202. The cover portion 201 is a cover having a substantially U-shape in plan view and is fixed to the wall surface W by a plurality of bolts 150. The mounting table 202 is fixed on the cover portion 201 via a plurality of elastic rubbers 203. The water heater 100 is positioned above the mounting table 202 and screwed to the mounting table 202. Then, a bracket 101 attached to the upper part of the back surface of the water heater 100 is fixed to the wall surface W.

[0004] The cover portion 201 is arranged so as to surround the front side and the left and right sides of a pipe connected to the bottom of the water heater 100. Such an anti-vibration mount 200 can absorb part of vibrations and noises from the fan in the water heater 100 by the elastic rubbers 203. Therefore, it is possible to suppress the vibrations and noises from the fan from being directly transmitted to the wall surface W.

Summary of the Invention

Problems to be Solved by the Invention

[0006] For example, in the case of a water heater installed on the wall of a high-rise apartment building, strong winds may blow upwards from below. The bottom of the cover portion 201 is open downwards. As a result, if a large amount of air flows into the cover portion 201 through the open bottom, a large pressure difference may be created between the inside and outside of the cover portion 201, potentially placing a heavy load on the cover portion 201.

[0007] The object of the present invention is to provide a vibration-damping mount that can suppress the occurrence of a pressure difference between the inside and outside of the cover portion. [Means for solving the problem]

[0008] The vibration-damping stand according to claim 1 is fixed to a wall surface and comprises a cover portion that covers and conceals piping extending downward from the bottom of a water heater, and a mounting base fixed on the cover portion via an elastic body, wherein the water heater is fixed to the mounting base in such a manner that it is mounted on the upper side, and the elastic body reduces the transmission of vibrations generated from the water heater to the wall surface, wherein the cover portion comprises a front plate located in front of the piping connected to the bottom, a pair of side plates extending rearward from both left and right ends of the front plate and located on both the left and right sides of the piping, a rear beam member fixed between the rear ends of each of the pair of side plates and extending in the left and right direction, and a suppression member fixed to the lower ends of each of the pair of side plates and suppressing the inflow of outside air from below into the inside of the cover portion.

[0009] At least one of the front plate and the pair of side plates of the vibration-damping mount according to claim 2 may be provided with an opening for inserting the inside and outside of the cover portion.

[0010] The suppressing member of the vibration isolation mount according to claim 3 is made of sheet metal, and the lower surface of the suppressing member may be provided with a pair of inclined surfaces that slope upward from the lowest end located on the left-right side of the center of the lower surface.

[0011] The suppression member of the vibration isolation mount according to claim 4 is made of sheet metal, and the lower surface of the suppression member may be provided with an inclined surface that slopes upward from the lowest end located at one end of the lower surface in the left-right direction toward the other end. [Effects of the Invention]

[0012] According to the vibration isolation mount of claim 1, the cover portion of the vibration isolation mount is fixed to the wall surface, and a mounting base is fixed to the cover portion via elastic rubber. The water heater is fixed in such a manner that it is placed on the upper side of the mounting base. Since the vibrations caused by the operation of the water heater are absorbed by the elastic rubber, the vibration isolation mount can suppress the transmission of vibrations from the water heater to the wall surface via the mounting base and cover portion. Furthermore, a suppression member fixed to the lower side of the cover portion suppresses the forceful inflow of wind blowing upward from below into the inside of the cover portion. As a result, the vibration isolation mount can suppress the generation of a pressure difference between the inside and outside of the cover portion.

[0013] According to the vibration isolation mount of claim 2, the pressure difference that occurs between the inside and outside of the vibration isolation mount due to the opening can be further suppressed.

[0014] According to the vibration isolation mount of claim 3, the air blown upward from below onto the pipe cover can be released to both the left and right sides by the pair of inclined surfaces of the suppression member.

[0015] According to the vibration isolation mount of claim 4, the air blown upward from below onto the vibration isolation mount can be released to the other end in the left-right direction by the inclined surface of the lower plate. [Brief explanation of the drawing]

[0028] The upper front beam 43 is installed between the upper part of the front end of the right plate 41 and the upper part of the front end of the left plate 42. The lower front beam 44 is installed between the lower part of the front end of the right plate 41 and the lower part of the front end of the left plate 42. The upper rear beam 45 is installed between the upper part of the rear end of the right plate 41 and the upper part of the rear end of the left plate 42. Fixing holes 451 are provided on both the left and right sides of the upper rear beam 45. The lower rear beam 46 is installed between the lower part of the rear end of the right plate 41 and the lower part of the rear end of the left plate 42. Fixing holes 461 are provided on both the left and right sides of the lower rear beam 46.

[0029] The front plate 47 is a sheet metal that is roughly rectangular in shape when viewed from the front. The front plate 47 is detachably fixed from the front to an opening that is roughly rectangular in shape when viewed from the front, which is formed by the upper front beam 43, the lower front beam 44, the front end of the right plate 41, and the front end of the left plate 42.

[0030] The bottom of the cover portion 40 having the above structure opens downwards. A closing plate 80 is fixed from below to the opening bottom of the cover portion 40. The closing plate 80 is made of sheet metal. The closing plate 80 is roughly rectangular in shape when viewed from below. A rib 81 is provided projecting upwards from the rear end of the closing plate 80. The rib 81 is locked from the rear to the rear surface of the lower rear beam 46 of the cover portion 40.

[0031] A pair of fixing holes 82 spaced apart in the front-to-back direction are provided at the right end of the closing plate 80. The pair of fixing holes 82 are aligned with a pair of fixing holes 56 provided in the lower piece 512 of the right plate 41 of the cover portion 40, and screws 91 are fastened from below. On the other hand, a pair of fixing holes 83 spaced apart in the front-to-back direction are provided at the left end of the closing plate 80. The pair of fixing holes 83 are aligned with a pair of fixing holes 57 provided in the lower piece 522 of the left plate 42 of the cover portion 40, and screws 91 are fastened from below. As a result, the closing plate 80 is fixed to the open bottom of the cover portion 40. Therefore, the closing plate 80 closes the open bottom of the cover portion 40.

[0032] Referring to Figure 4, the structure of the mounting base 30 will be described. The mounting base 30 comprises a rear portion 31, a right portion 32, and a left portion 33. The rear portion 31 is the part located at the rear of the mounting base 30, extends in the left-right direction, and is an angle member with a roughly L-shaped cross-section perpendicular to the length direction and inverted vertically. The rear portion 31 comprises a vertical surface portion 311 and an upper surface portion 312. The vertical surface portion 311 is roughly rectangular in shape, elongated in the left-right direction when viewed from the rear, and its surface direction is oriented in the front-rear direction. The vertical surface portion 311 is provided with a plurality of holes, including fixing holes 37, 37. The upper surface portion 312 protrudes rearward from the upper end of the vertical surface portion 311 and is roughly rectangular in shape when viewed from above, elongated in the left-right direction.

[0033] The right side portion 32 extends forward from the right end of the rear side portion 31. The cross section perpendicular to the longitudinal direction of the right side portion 32 is a roughly U-shaped angle member that opens to the left. The lower plate portion 321 located below the right side portion 32 is provided with a pair of fixing holes (not shown) spaced apart in the front-rear direction.

[0034] The left side portion 33 extends forward from the left end of the rear side portion 31. The cross-section of the left side portion 33 perpendicular to its length is a roughly U-shaped angle member that opens to the right. The lower plate portion 331 located below the left side portion 33 is provided with a pair of fixing holes 35 spaced apart in the front-rear direction.

[0035] Referring to Figures 3 and 4, the method for fixing the vibration isolation mount 20 and the water heater 1 to the wall W will be explained. First, the worker brings the upper rear beam 45 and the lower rear beam 46 of the cover section 40 into contact with the wall W, and then fixes the two fixing holes 451 on both the left and right sides of the upper rear beam 45 with bolts 7 (see Figure 2), and the two fixing holes 461 on both the left and right sides of the lower rear beam 46 with bolts 7 (see Figure 2). This fixes the cover section 40 to the wall W.

[0036] Next, as shown in Figure 4, a pair of elastic rubbers 60 are placed on a pair of fixing holes (not shown) provided on the upper surface of the upper piece 511 of the right plate 41 of the cover portion 40. On the other hand, a pair of elastic rubbers 60 are placed on a pair of fixing holes (not shown) provided on the upper surface of the upper piece 521 of the left plate 42.

[0037] Next, the mounting base 30 is placed on top of the cover portion 40 on which the four elastic rubbers 60 are arranged. At this time, the lower plate portion 321 of the right side portion 32 of the mounting base 30 is placed on the upper surface of the upper piece 511 of the right plate 41 on which the pair of elastic rubbers 60 are arranged. The pair of elastic rubbers 60 are interposed between the upper piece 511 and the lower plate portion 321. On the other hand, the lower plate portion 331 of the left side portion 33 of the mounting base 30 is placed on the upper surface of the upper piece 521 of the left plate 42 on which the pair of elastic rubbers 60 are arranged. The pair of elastic rubbers 60 are interposed between the upper piece 521 and the lower plate portion 331.

[0038] Then, on the right side 32 of the mounting base 30, bolts 92 are inserted from above into a pair of front and rear fixing holes (not shown) provided in the lower plate 321, and then inserted through two shaft holes (not shown) of elastic rubber 60 into a pair of fixing holes (not shown) provided in the upper piece 511, and fastened with nuts 95. On the other hand, on the left side 33 of the mounting base 30, bolts 92 are inserted from above into a pair of front and rear fixing holes 35 provided in the lower plate 331, and then inserted through two shaft holes (not shown) of elastic rubber 60 into a pair of fixing holes (not shown) provided in the upper piece 521, and fastened with nuts 95. As a result, the mounting base 30 is fixed to the upper part of the cover 40 via four elastic rubber 60 (see Figure 5).

[0039] Next, the worker positions the housing 2 of the water heater 1 on the upper part of the mounting base 30 fixed to the cover portion 40. At this time, the bracket 19 of the housing 2 is positioned in front of the vertical surface portion 311 of the rear portion 31 of the mounting base 30. The pair of fixing holes 191, 192 provided in the bracket 19 and the pair of left and right fixing holes 37, 37 provided in the vertical surface portion 311 overlap in the front-to-back direction. The worker inserts bolts 95, 95 (see Figure 3) from the front into the fixing holes 191, 192 and fixing holes 37, 37 and fastens them. This fixes the bracket 19 to the vertical surface portion 311 of the mounting base 30.

[0040] Then, the right fixing piece 17 of the frame 10 is brought into contact with the upper rear corner of the right side of the right plate 41 from the right, and a bolt 96 is inserted from the right into the fixing hole 171 of the right fixing piece 17 and fastened to the fixing hole 411 provided in the upper rear corner of the right plate 41. On the other hand, the left fixing piece 18 of the frame 10 is brought into contact with the upper rear corner of the left side of the left plate 42 from the left, and a bolt (not shown) is inserted from the left into the fixing hole 181 of the left fixing piece 18 and fastened to the fixing hole (not shown) provided in the upper rear corner of the left plate 42. In this way, the housing 2 of the water heater 1 is fixed to the mounting base 30.

[0041] Finally, the upper wall portion 11 of the housing 2 is fixed to the wall surface W with the bracket 4. This fixes the vibration-damping mount 20 and the water heater 1 to the wall surface W.

[0042] The effects of the vibration isolation mount 20 will now be explained. As shown in Figures 1 and 2, the housing 2 of the water heater 1 is fixed to the upper part of the cover 40 via four elastic rubbers 60 fixed to the upper part of the mounting base 30. With this configuration, some of the vibration and noise from the fan inside the housing 2 is absorbed by the four elastic rubbers 60. Therefore, the vibration isolation mount 20 can reduce the vibration and noise transmitted from the housing 2 to the wall surface W.

[0043] As described above, the bottom opening of the cover portion 40 is closed by the closing plate 80. This effectively prevents strong winds blowing up from below from entering the inside of the cover portion 40, especially on the walls W of high-rise apartment buildings. Therefore, the vibration isolation mount 20 can suppress the occurrence of a large pressure difference between the inside and outside of the cover portion 40, thereby suppressing a large load on the cover portion 40.

[0044] In the above description, the bottom wall portion 14 of the housing 2 is an example of the "bottom portion of the water heater" of the present invention. The elastic rubber 60 is an example of the "elastic body" of the present invention. The right plate 41 and the left plate 42 are examples of the "pair of side plates" of the present invention. The upper rear beam 45 and the lower rear beam 46 are examples of the "rear beam members" of the present invention. The closing plate 80 is an example of the "restraining member" of the present invention.

[0045] As described above, the vibration isolation stand 20 of this embodiment comprises a cover portion 40 and a mounting base 30. The cover portion 40 is fixed to the wall surface W and covers the piping that extends downward from the bottom surface of the water heater 1. The mounting base 30 is fixed on the cover portion 40 via four elastic rubbers 60. The water heater 1 is fixed to the mounting base 30 in such a manner that it is mounted on the upper side. The vibration isolation stand 20 reduces the transmission of vibrations generated from the water heater 1 to the wall surface W by the four elastic rubbers 60. The cover portion 40 comprises a front plate 47, a right plate 41, a left plate 42, an upper rear beam 45, a lower rear beam 46, and a closing plate 80. The front plate 47 is located in front of the piping connected to the bottom of the housing 2. The right plate 41 and the left plate 42 extend rearward from both the left and right ends of the front plate 47 and are located on both the left and right sides of the piping. The upper rear beam 45 and the lower rear beam 46 are fixed between the respective rear ends of the right plate 41 and the left plate 42. The upper rear beam 45 and the lower rear beam 46 extend in the left-right direction and have fixing holes 451 and 461 for fixing to the wall surface W. The closing plate 80 is fixed to the respective lower ends of the right plate 41 and the left plate 42, suppressing the inflow of outside air from below into the inside of the cover portion 40. As a result, the vibration isolation frame 20 can suppress the formation of a pressure difference between the inside and outside of the cover portion 40.

[0046] It should be noted that the present invention is not limited to the above embodiments, and various modifications are possible. Although four elastic rubbers 60 are arranged on the upper part of the cover portion 40, the number of elastic rubbers 60 may be more or less than this. The material is not limited to rubber, as long as it is an elastic body instead of elastic rubber 60. The shape of the elastic rubbers 60 is also not limited to the above embodiments.

[0047] For example, as shown in the first modified example in Figure 6, the right plate 41 of the cover portion 140 of the vibration isolation mount 120 is provided with an opening 70 consisting of multiple slits. The opening 70 allows the inside and outside of the cover portion 140 to pass through. By providing this opening 70, the pressure difference between the inside and outside of the cover portion 140 can be further suppressed. The opening 70 may be provided in any of the right plate 41, the left plate 42, and the front plate 47, for example, in any two of them, or in all of them. Furthermore, the shape of the holes in the opening 70 is not limited to slits, and is not particularly limited as long as it is an opening.

[0048] Furthermore, although the closure plate 80 in the above embodiment is a single flat plate, the wind blowing up from below may be directed in a specific direction by, for example, providing a slope on the lower surface of the closure plate 80.

[0049] For example, as shown in the second modified example in Figure 7, a closure plate 180 is fixed to the bottom of the cover portion 240 of the vibration isolation mount 220. A guide surface 185 is formed on the lower surface of the closure plate 180. The guide surface 185 extends downward in a roughly arc shape as it is directed to the right in a front view. As a result, wind blowing up from below is guided to the left along the guide surface 185, thereby reducing the wind pressure acting on the closure plate 180.

[0050] For example, as shown in the third modified example in Figure 8, a closure plate 280 is fixed to the bottom of the cover portion 340 of the vibration isolation mount 320. The lower surface of the closure plate 280 is formed in a curved shape, with the center in the left-right direction of a front view being the lowest point. A pair of guide surfaces 285 and 286 are formed on both the left and right sides. The guide surfaces 285 and 286 are gently sloped in a roughly arc shape as they extend towards the left and right sides. As a result, wind blowing up from below is guided to both the left and right sides along the guide surfaces 285 and 286, thereby reducing the wind pressure on the closure plate 280.

[0051] Furthermore, as described above, the closure plate 80 in the above embodiment is a single flat plate, but it does not have to be flat as long as it can provide resistance to the wind blowing up from below. Instead of the closure plate 80, for example, a mesh filter member may be fixed to the bottom of the cover portion 40. In addition, one or more openings may be provided in the closure plate 80, or slits may be provided.

[0052] Furthermore, in the above embodiment, fixing holes 451 and 461 are provided in the upper rear beam 45 and the lower rear beam 46 in order to fix the cover portion 40 to the wall surface W. However, the portion to be fixed to the wall surface W may be a portion other than the upper rear beam 45 and the lower rear beam 46. For example, the rear ends of the right plate 41 and the left plate 42 may be fixed to the wall surface W. [Explanation of Symbols]
