Description

The present invention relates to equipment, and in particular to equipment that is installed in pipe shafts (PS) in apartment buildings and that has improved maintainability.

When installing a water heater or heat source unit in the pipe shaft of an apartment building, the hot water storage tank unit is installed inside the pipe shaft, and the auxiliary heat source unit (water heater) and the main heat source unit (heat pump or water heater) are lined up and fixed to the frame at the opening of the pipe shaft.
As a result, the case shapes of the auxiliary heat source unit and the main heat source unit are narrow and long, and when performing maintenance on these devices, one-way maintenance is required by opening only the front door of the device and performing maintenance only from the front side.

In the fuel cell system described in Patent Document 1, the front of the housing main body is configured with left and right doors that open like a double door, modular components such as a combustor, fuel cell stack, reformer, evaporator, and heat exchanger are arranged on the left side inside the housing main body, and detectors, a fuel gas supply device, an oxidizing gas supply device, a water supply device, etc. are arranged on the right side inside the housing main body, and a power conversion device and a control device are attached to the inside surface of the right door.

This fuel cell system is also equipped with equipment on the inside of the right door, so that when maintenance is required, the left and right doors can be opened and maintenance can be performed from the front of the housing main body and the inside of the right door, making it easy to maintain.
On the other hand, in the water heater mounting structure (inside-door installation type) described in Patent Document 2, the water heater is mounted to a fixed frame on the front of the pipe shaft via a mounting member, and its exhaust pipe protrudes from an opening formed in a door that opens and closes the front side of the water heater.

Patent No. 5524693 JP 2022-19081 A

However, when equipment such as a water heater or hot water supply device is fixed to the frame of the opening of the pipe shaft, the tip of the exhaust pipe extending from the equipment body will protrude from an opening hole formed in a rotating front cover that is hinged to the equipment body and an opening formed in the door on the front side of the cover. In this case, when the front cover is opened by rotating it, it is difficult to smoothly remove the tip of the exhaust pipe from the opening hole and the opening.

In particular, if the thickness of the front cover is increased and equipment is installed on the inside of the front cover, the movement trajectory of the opening hole when the front cover is opened will not be parallel to the exhaust pipe but will move in a direction that intersects with the exhaust pipe, making it difficult to smoothly remove the tip of the exhaust pipe from the opening hole.

The object of the present invention is to provide equipment that is installed in a pipe shaft of an apartment building, and that allows the tip of a tubular body such as an exhaust pipe to be smoothly removed from an opening formed in the front cover when the front cover is opened.

The equipment of claim 1 is equipment installed in a pipe shaft of an apartment building, and the equipment comprises a box-shaped equipment body with an opening at the front and a front cover that covers the opening, and the front cover has an opening hole through which a portion near the tip of a cylindrical body such as an exhaust pipe protrudes. The front cover is connected at one end to the equipment body by a hinge member, and is configured to rotate around the hinge member as a fulcrum to open and close during maintenance, and the cylindrical body is configured to be expandable and contractible so as to reduce its length in the front-to-rear direction.

According to the above configuration, the facility equipment includes a box-shaped equipment body with an opening at the front and a front cover that covers the opening, and an opening hole is formed in the front cover into which the tip of a cylindrical body such as an exhaust pipe is inserted. During maintenance, the front cover is opened by rotating it around the hinge member as a fulcrum. At this time, before opening the front cover, the cylindrical body such as the exhaust pipe is reduced in length in the front-rear direction to remove its tip from the opening hole formed in the front cover, and then the front cover is opened. Therefore, the tip of the cylindrical body does not interfere with the opening hole.

In particular, even if the interior surface of the front cover is fitted with equipment, the length of the cylindrical body in the front-to-rear direction is reduced and the tip of the cylindrical body is removed from the opening in the front cover before the front cover is opened, so the tip of the cylindrical body does not interfere with the opening.

The equipment of claim 2 is characterized in that, in the invention of claim 1, the cylindrical body is configured so that a plurality of tubular members form a spigot structure, and a sealing member is attached between the tubular members.
According to the above configuration, the spigot structure allows the cylindrical body to be expandable and contractable with a simple structure, and sealing performance can be ensured by the sealing member.

The equipment of claim 3 is characterized in that, in the invention of claim 1 or 2, the hinge member is configured to be able to separate the front cover from the equipment main body by moving the front cover upward a predetermined distance.
According to the above configuration, since the front cover can be separated from the device body, the workability of installation and maintenance work can be improved.

The facility equipment of claim 4 is the invention of claim 1 or 2, characterized in that electrical components such as a control board and a power supply board of the facility equipment are mounted on the inner surface side of the front cover.
According to the above configuration, by opening the front cover, electrical components such as the control board and power supply board can be exposed to the outside world, thereby improving the maintainability of electrical components that are prone to malfunctions and other problems.

As described above, the present invention has excellent effects.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings.
As shown in Figures 1 to 7, an installation structure for equipment, a hot water supply device 1, is installed in a pipe shaft 2 of an apartment building. In Figure 1, F indicates the front, U indicates the upper side, and L indicates the left side. A water pipe 3, a gas supply pipe 4, etc. are installed in the pipe shaft 2, and a metal frame 6 is fixed to the opening on the front side of the pipe shaft 2.

The hot water supply device 1 comprises a box-shaped device body 10 with an opening 7 (see FIG. 7) on the front side, and a front cover 11 that covers the opening 7. The front cover 11 is configured to be able to be opened and closed by rotating around a hinge member 12 as a fulcrum.

The metal frame 6 is made of steel and has an outer peripheral frame 6a installed on the front outer periphery of the pipe shaft opening, a horizontal frame member 6b that crosses the middle section of the outer peripheral frame 6a, and a vertical frame member 6c that is arranged to divide the equipment installation area above the horizontal frame member 6b into a left area 13a and a right area 13b in a ratio of approximately 2:5. The outer peripheral frame 6, horizontal frame member 6b, and vertical frame member 6c each have a flange portion.

The water heater 1 is attached to the right region 13b of the metal frame 6 via a mounting frame 14, generally referred to as a door case. The mounting frame 14 is a rectangular cylinder having a predetermined front-to-rear length, and has a left side member 14a, a right side member 14b, an upper side member 14c, and a lower side member 14d. The water heater 1 is inserted and fixed from the front side into a rectangular mounting opening 14k of a mounting wall portion 14e formed at the rear end of these side members, and the mounting frame 14 is fixed to the metal frame 6 with multiple screws, thereby attaching the water heater 1 to the metal frame 6. However, the front end of the front cover 11 is located behind the front end of the mounting frame 14. In addition, a door 30 (see FIG. 7) that opens and closes the front side of the front cover 11 is hinged to the front end of the metal frame 6.

As shown in FIG. 4, the front cover 11 of the water heater 1 is formed into a rectangular box-like body with a front-to-rear length approximately equal to that of the mounting frame 14, and the upper end, middle section, and lower end of the right end of the front cover 11 are each connected to the right end of the device body 10 by hinge members 12, and are configured to rotate around the hinge members 12 to open and close during maintenance.

As shown in Figures 4 and 7, each hinge member 12 has a tubular member 12a fixed to the right end of the device body 10, a pin member 12b protruding upward from the tubular member 12a, and a tubular member 12c fixed to the right end of the front cover 11, into which the pin member 12b is inserted.

When installing or maintaining the hot water supply device 1, the front cover 11 can be moved upward by a predetermined distance, causing the tubular member 12c to come off the pin member 12b, allowing the front cover 11 to be separated from the device body 10 as required. Figure 7 is a perspective view of the front cover 11 removed from the device body 10, and Figure 4 is a perspective view of the removed front cover 11. The right edge member 14b of the mounting frame 14 has a left-right width equal to or greater than the front-to-rear length of the front cover 11, in order to open and close the front cover 11 by rotating it about the hinge member 12 as a fulcrum during maintenance.

The water heater 1 is a gas combustion water heater, and has a heating and combustion module 15, auxiliary equipment 16, a power supply board 17, and a control board 18. The auxiliary equipment 16 has a fuel gas supply means, a combustion air supply means, a water supply means, a flow rate adjustment means, etc.

As shown in FIG. 7, when the front cover 11 is removed during maintenance, the front of the heating and combustion module 15 installed in the upper part of the inside of the device body 10 and the front of the auxiliary equipment 16 installed in the lower part of the inside of the device body 10 are open.

Furthermore, electrical equipment such as a power supply board 17 and a control board 18 are attached inside the front cover 11, and when the front cover 11 is removed, the power supply board 17 and the control board 18 are in an open state.
It should be noted that harnesses are connected to the power supply board 17 and the control board 18 via connectors, respectively, but these are omitted from the illustration.

As shown in Figures 4 and 7, a cylindrical body 20 such as an exhaust pipe is provided extending forward from the front surface of the thermal combustion module 15, and an opening hole 21 is formed in the front cover 11 through which the portion near the tip of the cylindrical body 20 protrudes. In addition, an opening hole 31 is formed in the door 30 through which the tip of the cylindrical body 20 protrudes.

As shown in Figures 8 to 10, the cross-sectional shape of the cylindrical body 20 is an oval that is elongated in the left-right direction, and the cylindrical body 20 is configured so that multiple cylindrical members 22 to 24 of different thicknesses form a spigot structure (telescopic structure), and a seal member 25 is attached between the cylindrical members 22 to 24 and the cylindrical members 22 to 24. In this way, the cylindrical body 20 is configured to be expandable and contractable so that its length in the front-rear direction is reduced when the front cover 11 is opened. In addition, in the normal state of use, the cylindrical member 24 at the most distal end protrudes from the opening hole 31 of the door 30.

Next, the effects of the above-described hot water supply apparatus 1 will be described.
The front cover 11 is formed into a rectangular box-like body having a specified front-to-rear length, and the right end of the front cover 11 is rotatably connected to the right end of the device body 10 via a hinge member 12. Therefore, when the front cover 11 is rotated to the open state during maintenance, for example, the front surface of the device body 10 and the inner surface of the front cover 11 are opened, so that the maintainable area is doubled, thereby significantly improving maintainability.

The front cover 11 can be removed from the device body 10, so that the front cover 11 can be removed from the device body 10 as necessary during installation or maintenance, improving workability.

Since the front cover 11 has a predetermined front-to-rear length, when the front cover 11 is rotated around the hinge member 12 to open it, the movement direction of the opening hole 21 of the front cover 11 and the opening hole 31 of the door 30 intersects with the direction of the tubular member 20, causing interference between the tubular member 20 and the opening holes 21, 31, which may prevent the front cover 11 from being opened smoothly.
Therefore, by making the multiple tubular members 21 to 23 of the tubular body 20 into a spigot structure, reducing the front-to-rear length of the tubular body 20 before opening the front cover 11, and retracting the tip of the tubular body 20 rearward from the opening holes 21, 31, interference between the tubular body 20 and the opening holes 21, 31 can be prevented, and the front cover 11 can be opened smoothly.

The cylindrical body 20 is constructed by connecting multiple cylindrical members 22 to 24 in a spigot structure, so that the cylindrical body 20 can be stretched and contracted with a simple structure. In addition, a seal member 25 is attached between the cylindrical members 21 to 23 and the cylindrical members 21 to 23, so that rattling of the spigot structure is eliminated and sealing performance is ensured.

By using a separable hinge member as the hinge member 12, the front cover 11 is configured to be separable from the device body 10, which improves the ease of installation and maintenance of the water heater 1.

Electrical components such as the control board 18 and power supply board 17 of the water heater 1 are attached to the inside of the front cover 11, so that by opening the front cover 11, electrical components such as the control board 18 and power supply board 17 can be exposed, improving the maintainability of electrical components that frequently break down or malfunction.

Next, an example in which the above embodiment is partially modified will be described.
1) Although the above description has been given taking as an example a case in which a hot water supply device 1 is installed as facility equipment, the facility equipment is not limited to a hot water supply device, and may be a heat pump unit or a fuel cell unit.
2) The cross section of the cylindrical body 20 is not limited to an elliptical shape, but may be a circular shape.

3) In the above description, the front cover 11 of the equipment is connected to the right end of the equipment body 10 via the hinge member 12, but it is also possible to connect the front cover 11 to the left end of the equipment body 10 via the hinge member 12.

4) The present invention is also applicable to the case where facility equipment is installed in the left area 13a of the equipment installation area.
5) In addition, those skilled in the art can implement the above-described embodiments by making various modifications, and the present invention also includes such modifications.
