Description

  The present invention relates to a heating apparatus such as a combustion apparatus or a hot water supply apparatus, and relates to a heating apparatus that can prevent electric leakage of electrical equipment in the heating apparatus. The heating device of the present invention is suitably used as a hot water supply device. Moreover, this invention relates to the space formation member which ensures a predetermined space in the exterior case of a heating apparatus.

The hot water supply device is a heating device that heats water with a burner or the like. In other words, the hot water supply device has a heat exchanger that allows water to pass through the outer case and a combustion device such as a burner, and the water that passes through the heat exchanger is heated with the combustion gas of the burner to produce hot water. Device.
Since the hot water supply apparatus has a heat exchanger and a water pipe in the outer case, there is a concern that the residual water inside the pipe may freeze in a severe cold season.
For this reason, some outer cases are provided with a freeze prevention heater.

The freeze prevention heater not only needs to be mechanically attached to a pipe or the like, but also needs to be electrically connected to a relay or the like. That is, since the anti-freezing heater is an electric device, it requires electric wiring for feeding. And in today's freeze prevention heater, a connector piece is attached to the wiring to facilitate wiring work.
That is, the anti-freezing heater has a heat generating part and a power supply line part, and a connector piece is attached to the end of the power supply line part.
In the anti-freezing heater, the heat generating portion is mechanically attached to a pipe or the like by a known fixture. Electrically, it is connected via the connector described above.
That is, a connecting wire is connected to a terminal of a control board to which a relay or the like is attached, and a connector piece is attached to the tip of the connecting wire.
Then, the connector piece on the anti-freezing heater side and the connector piece on the relay side are fitted together to complete the electrical wiring of the anti-freezing heater.

The outer case 2 is largely divided into a main body portion 17 and a front lid 18. That is, the back surface 12, the left and right side surfaces 13 and 14, the top surface 15, and the bottom surface 16 are integrally formed to constitute the main body portion 17. The front lid 18 is a separate member from the main body 17 and covers the opening on the front surface of the main body 17 with a screw (not shown).

  A small window 20 is provided on the front lid 18. The small window portion 20 is an opening provided in a central portion in the left-right direction below the front lid 18 and is normally closed by the small lid 19. That is, the small window portion 20 is attached with a small lid 19 by screws (not shown). When the small lid 19 is removed, the small window portion 20 is opened as shown in FIG.

As shown in FIGS. 9 to 13, three wire insertion holes 21, 22, and 23 are provided on the bottom surface 16 of the main body portion 17 of the exterior case 2. In addition, conduit connecting short pipe members 25, 26, and 27 are mounted in the wire insertion holes 21, 22, and 23, respectively.

The short tube members 25, 26, and 27 for connecting the conduits are attached to the bottom surface 16 of the exterior case 2 by engaging a thin nut 29 with the short tube portion 31 protruding from the exterior case 2.

Next, the space forming member 10 which is a characteristic constituent member of the present embodiment will be described. The space forming member 10 is made by resin injection molding, and a space forming portion 35 is provided on the base portion 33 as shown in FIGS. Further, two short pipe portions 36 and 37 are suspended from the base portion 33.
That is, the base portion 33 is a portion that constitutes a seat that contacts the bottom surface 16 of the outer case 2 and that forms the proximal ends of the short tube portions 36 and 37.
The base portion 33 is substantially rectangular in plan view. However, a large arc 38 is drawn on the corner side of the portion to be disposed on the back side of the exterior case 2.

The base portion 33 has a three-stage outer shape. That is, the outermost region 40 has a low height, the slightly inner region 41 has an intermediate height, and the central region 43 has a high height.
The base portion 33 has the largest area in the central region 43. A central region 43 of the base portion 33 is flat.
However, since the short pipe portions 36 and 37 are suspended from the central region 43 of the base portion 33 as a base end, the short pipe portions 36 and 37 are opened.

  The bottom surface side of the base portion 33 is similar to the outer shape as shown in FIGS. 7 and 6 and is entirely concave. That is, the inner region 41 has a medium height, and the central region 43 has a high height. For this reason, a concave portion constituted by a slightly inner region 41 and a central region 43 exists on the bottom surface side of the base portion 33.

  The two short pipe portions 36 and 37 have outer diameters smaller than the inner diameters of the above-described conduit pipe connecting short pipe members 25, 26 and 27. The two short pipe portions 36 and 37 are parallel, and the distance between them is equal to the distance between the wire insertion holes 21 and 22 provided in the bottom surface 16 of the outer case 2.

The space forming portion 35 has a structure in which the left and right side surface portions 50 and 51, the back surface portion 52, and the top surface portion 53 are covered and the front side 55 is opened. However, the left and right side surface portions 50, 51, the back surface portion 52, and the top surface portion 53 are connected by gentle curved surfaces, and the boundary between them is not clear.
However, at least the space forming portion 35 is open on the front side 55. At least the top surface portion 53 has a flat surface 56.
Further, there is an inclined wall portion 57 between at least the flat surface 56 of the top surface portion 53 and the back surface portion 52 as shown in FIGS.

A wiring locking portion 60 is provided on the inclined wall portion 57 described above. The wiring latching portion 60 is a hook and projects from the outer surface of the outer shape of the space forming member 10 in a cantilever manner.
That is, the wiring latching portion 60 has a thin line shape or a plate shape, and one end thereof is integrally connected to the inclined wall portion 57 of the space forming member 10 and the other end side is opened. Therefore, the wiring latching portion 60 is cantilevered, and the wiring latching portion 60 is made of resin and has elasticity, so that the posture of the free end 61 side can be changed in the approaching / separating direction with respect to the inclined wall portion 57. is there.
5 and FIG. 8, the wiring locking part 60 has a “<” shape when viewed from the side, and is bent from the rising part 63 that is raised in the vertical direction and the rising part 63. A horizontal posture portion 62 is provided. The height of the highest position of the horizontal posture portion 62 is the same height as the flat surface 56 of the top surface portion 53 or slightly lower than the flat surface 56.
In the present embodiment, the rising portion 63 is a fixed end connected to the lower side of the inclined wall portion 57, and the end portion of the horizontal posture portion 62 is the free end 61.

Further, as described above, the wiring locking portion 60 is provided on the inclined wall portion 57, the wiring locking portion 60 has a fixed end at the rising portion 63, and the rising portion 63 is raised in the vertical direction. Therefore, the rising portion 63 extends in a direction away from the inclined wall portion 57.
On the other hand, since the leading end of the rising portion 63 is bent and connected to the horizontal posture portion 62, the leading end side of the wiring locking portion 60 that is the free end 61 approaches the inclined wall portion 57.
In this way, the wiring latching portion 60 once extends in a direction away from the outline of the space forming member 10 and draws a curve so that the free end 61 side approaches the outline of the space forming member 10. A space 65 is formed between the outer shell of the member 10 (the inclined wall portion 57). Further, since the posture of the free end 61 side of the wiring locking portion 60 can be changed in the approaching / separating direction with respect to the inclined wall portion 57, the space 65 has a degree of freedom in the expansion / contraction direction.

The space forming portion 35 is on the base portion 33, and the space forming portion 35 is covered with the left and right side portions 50 and 51, the back surface portion 52, and the top surface portion 53. A space 66 is surrounded by the base portion 33.
That is, the bottom surface of the space 66 is covered with the base portion 33, and is covered with the left and right side surface portions 50, 51, the back surface portion 52, and the top surface portion 53 of the space forming portion 35, and only the front side is open.

When attention is paid to the open side (front side) of the space forming member 10, one corner (left side in FIG. 4) of the top surface portion 53 is largely omitted, and the top surface notch portion 75 is formed. In other words, the portion excluding one corner of the top surface portion 53 protrudes in a bowl shape with respect to the base portion 33.
The open end side of the left side surface portion 50 is notched according to the notch amount of the top notch portion 75. That is, a side cutout portion 78 is formed in a part of the left side surface portion 50.
On the other hand, the lower corner portion has a slightly raised base portion 33 to form a small collar portion 77. That is, the base portion 33 is slightly lifted to form a gavel portion 77 in the lower right corner portion with reference to FIG.

Next, the positional relationship between the space forming member 10 and the outer case 2 will be described.
As shown in FIGS. 9, 10, and 11, the space forming member 10 has two short pipe portions 36 and 37 inserted into the conduit pipe connecting short pipe members 25 and 26 provided on the bottom surface 16 of the exterior case 2. Yes. That is, the bottom surface 16 of the outer case 2 is provided with three wire insertion holes 21, 22, and 23, and short tube members 25, 26, and 27 for connecting conduits are attached to the bottom surface 16, respectively.
The short tube portions 36 and 37 of the space forming member 10 are inserted into two of the three conduit tube connecting short tube members 25, 26 and 27 on the left side of the drawing.

Therefore, the space forming member 10 is positioned in the front / rear / right / left direction and fixed in a state where it does not move except in the upward direction.
The conduit connecting short pipe members 25 and 26 have a flange portion 30 that protrudes from the bottom surface 16 of the outer case 2, but the base portion 33 of the space forming member 10 has a bottom surface. Since it is concave, the flange portion 30 enters the concave portion.
Moreover, the open surface (front side 55) of the space forming member 10 faces the front side, while the wiring locking part 60 is located on the back side.
Only the upper end side of the open surface (front side 55) of the space forming member 10 faces the small window portion 20.

  In addition, a concave groove-shaped gap is formed between the bottom surface 16 of the outer case 2 and the small collar portion 77 as shown in FIGS. 8, 10, 12, and 13. That is, a horizontal pulling path 78 is secured between the bottom surface 16 of the outer case 2 and the small collar portion 77.

  Further, the space 66 of the space forming member 10 is opened upward in the exterior case 2 by the top surface notch 75.

In the hot water supply apparatus 1 of the present embodiment, wiring of electrical devices (all not shown) such as a freeze prevention heater, a blower, a sensor, a relay, a solenoid valve, and a pump are all performed at the manufacturing factory of the hot water supply apparatus 1. . In this embodiment, the wiring including the wiring 70 for the anti-freezing heater is bundled by the wiring locking portion 60 of the space forming member 10. That is, a space 65 is formed between the wiring latching portion 60 and the outer shell (inclined wall portion 57) of the space forming member 10, and the wiring latching portion 60 is inclined by the elasticity of the wiring latching portion 60. Since the posture can be changed in the approach / separation direction with respect to 57, the space 65 has a degree of freedom in the enlargement / reduction direction. Also, the space between the free end 61 of the wiring locking portion 60 and the inclined wall portion 57 can be expanded by elasticity.
Therefore, the wiring locking part 60 is elastically deformed with fingers to open a space between the free end 61 and the inclined wall part 57, and the wiring 70 for the anti-freezing heater is sandwiched between the wiring locking parts 60, so that the anti-freezing heater The wiring 70 can be held.
Moreover, since the wiring latching | locking part 60 exists in the height away from the bottom face 16 of the exterior case 2, the wiring containing the wiring 70 for anti-freezing heaters is hold | maintained hollow.
As a result, the anti-freezing heater connector 71 is prevented from bottoming and is held hollow. For this reason, no leakage occurs in the hot water supply apparatus 1 of the present embodiment.

  In the assembly process at the factory, as described above, the relay box 72 is installed after the wiring locking portion 60 of the space forming member 10 is bundled and locked with the wiring 70 for the freeze prevention heater and other wirings. The lower surface of the relay box 72 is close to or abuts on the flat surface 56 of the top surface portion 53 of the space forming member 10. However, since the above-described wiring locking portion 60 is provided on the inclined wall portion 57 of the space forming member 10, the wiring locking portion 60 is located at a position lower than the top surface portion 53, and the wiring 70 and the wiring locking portion for the anti-freezing heater are used. 60 is not excessively suppressed by the relay box 72.

Next, electrical wiring at the construction site will be described.
As described above, the electrical work to be performed at the construction site is such that the power supply line is drawn into the outer case 2 and connected to a predetermined terminal of the outer case, or the remote control cord is drawn into the outer case, and the outer case 2 It is limited to the construction to connect to the predetermined terminal.

  In the present embodiment, as shown in FIGS. 12 and 13, the wires led out from the conduit tubes 80, 81, 82 are drawn into the exterior case 2 through the conduit tube connecting short tube members 25, 26, 27.

Here, since the short tube members 25 and 26 for connecting the conduit pipes are directly communicated with the space 66 in the space forming member 10, the electric wire enters the space 66 in the space forming member 10. When the electric wire is further pushed in, the electric wire comes into contact with the inner surface of the inclined wall portion 57 of the space forming member 10 and changes the traveling direction to the front side as indicated by an arrow in FIG. Therefore, the end portion of the electric wire advances to the worker side.
If the small lid 19 is removed with the front lid 18 closed and only the small window portion 20 is opened, the end of the electric wire will be pushed out of the small window portion 20. That is, the open side of the space forming member 10 is in a position facing the small window portion 20, and the space 66 and the small window portion 20 of the space forming member 10 communicate with each other. Pushed out.

  Then, for example, as shown in FIG. 12, the electric wires extend to other parts of the exterior case 2 via the top surface notch portion 75 or the side surface notch portion 78 provided on the left side of the space forming member 10, and the control plate 6 terminals.

In addition, the electric wire 85 drawn into the outer case 2 through the short tube member 27 for connecting the electric wire pipe passes through a horizontal pulling path 78 formed between the small flange portion 77 of the space forming member 10 and the bottom surface 16 of the outer case 2. Then, it passes through the space forming member 10 and is connected to the terminal of the terminal board 7 via the top notch 75 or the side notch 78.
When all the wiring is completed, the electric pipes 80, 81, and 82 are attached to the electric pipe connecting short pipe members 25, 26, and 27, and the electrical work is completed.

  According to the embodiment described above, since the electric wire in the outer case 2 can be held hollow, the risk of electric leakage can be reduced. Further, the bundle of electric wires in the outer case 2 is improved, and maintenance is facilitated. Furthermore, when installing the water heater, the electric wire can be pushed out to the operator side, so the workability is good.

  In the embodiment described above, the short tube portions 36 and 37 of the space forming member 10 are inserted into the short tube members 25 and 26 for connecting the conduit tube, but the short tube portions 36 and 37 of the space forming member 10 are used for connecting the conduit tube. The functions of the short tube members 25 and 26 may be provided, and the conduit tubes 80 and 81 may be directly connected to the short tube portions 36 and 37 of the space forming member 10. That is, like the space forming member 90 shown in FIG. 14, screws may be formed on the outer peripheral surfaces of the short pipe portions 91 and 92 so as to have the same function as the short pipe members 25 and 26 for connecting conduits.

In the embodiment described above, the space forming member 10 is provided with the two short pipe portions 36 and 37. This configuration has an effect of fixing the space forming member 10 in a plane and is an excellent configuration. This does not exclude a configuration in which there is one short pipe portion.
For example, only one short pipe portion 95 may be provided. When the number of the short pipe portions 95 is singular, the space forming member 10 may be rotated. For example, as with the space forming member 93 shown in FIG. By providing the portion 96, the degree of freedom in the rotation direction can be taken. Of course, the space forming member may be fixed with screws or the like.
Conversely, it may have three or more short pipe portions.
