Description

[Detailed Description of the Invention] The present invention relates to a punched part for piping, wiring, etc. of a protective cover that protrudes from the back of a heater to maintain a distance between the heater and other objects.

In gas/oil heating equipment, it has traditionally been necessary to attach a protective cover to the back of the unit in order to maintain a certain distance from the wall and to prevent flammable materials such as curtains from coming into contact with the exhaust stack. many.

Since this rear protective cover protrudes from the back of the main body toward a wall, etc., openings for air supply, exhaust pipes, and other wiring are provided at several locations at appropriate intervals to facilitate piping and wiring.

A concrete example of this is shown in FIGS. 1 and 2.

The configurations shown in Figures 1 and 2 are known prior to this application, and in the figures, 1 is the main body of the heater, 2 is an air supply pipe, 3 is an exhaust pipe, and 4 is a rear protective cover projecting at right angles from the back of the main unit. ,
5 is a discontinuous loop-shaped slit shown in FIG. 2, 6 is a punched part surrounded by this slit 5, and 7 is a part of the air supply pipe 2 and exhaust pipe 3 opened by punching out this punched part 6. This is the opening for the pilgrimage.

However, in this case, the position of the opening 7 is specified and the piping
If the wiring path is regulated and an opening is opened in the direction of the piping, the work must be detoured around the nearest opening, which unnecessarily complicates the work and increases piping costs.

In order to eliminate this drawback, it is possible to provide two or more punched parts 6 and narrow the mutual spacing between them, or to make the punched parts 6 into elongated holes. However, the latter has the same drawbacks and cannot be completely overcome, and the latter has more openings than necessary, making it easy for flammable materials to enter there, making it impossible to achieve the intended purpose as a protective cover.

The present invention has been made in view of the above points, and is aimed at making it possible to provide openings only in necessary areas.

Therefore, in this invention, openings are formed by punching out the required parts of the punching part through discontinuous loop-shaped slits.

That is, by punching out a first slit in the form of a discontinuous loop surrounding the punched part that serves as a passage for the wiring and piping of the heater in the protective cover that extends from the back of the heater to maintain a distance from other objects. In the protective cover forming a passage opening, the punched portion is provided with a second slit different from the first slit, and the punched portions are adjacent to each other via the second slit and have an area that is different from each other. It is formed from at least two or more parts with different values.

With this configuration, according to the present invention, the opening is formed by punching out a portion of the punched portion that is continuously formed through the second slit, through which the piping, etc. can pass through without detouring, and where the punching area is as small as possible. By forming an opening and passing a pipe, etc. through this opening, there is no need to detour the pipe, etc., which not only simplifies the work and reduces costs, but also minimizes the size of the opening required for the pipe. Since it can be made small and there is no need to provide any openings other than the punched parts, it can be expected to have the effect of preventing the intrusion of combustible materials and achieving the intended purpose as a protective cover.

The main part of one embodiment of the present invention will be explained below based on FIG. 3.

In this figure 3, the shape and installation position of the rear protective cover are shown in
Same as the figure.

11a is a discontinuous loop-shaped first slit, 11b is this first slit 11. The second slit is provided so as to divide the punched part surrounded by the first slit 11. into at least two (five in this embodiment) parts, and is formed in a discontinuous loop shape. intersects with

12 to 16 are the first slit 11a and the second slit 1
2. These punching parts have three different sizes and shapes: 12, 16, 13, 15, and 14.

A plurality of groups similar to these punched portions 12 to 16 may be formed in the longitudinal direction of the back protective cover 4, or a single group may be formed.

When in use, one or more of the punching parts 12, 13, 14, 15, or 16 are punched out in the shape and position most suitable for piping and wiring passages, thereby opening them to a predetermined size. Piping or wiring may be done through the opening.

As described above, the present invention allows the position, shape and size of the opening for piping wiring etc. to be freely selected from among a plurality of punched parts.
In addition, since the minimum necessary opening can be obtained, it is possible to prevent the intrusion of flammable materials, etc., and to fully fulfill the role of a cover to protect the rear surface, thereby achieving the initial objective of preventing the occurrence of fires, etc.

FIG. 2 is a detailed view of a conventional punching section, and FIG. 3 is a plan view showing details of a punching section according to the present invention. In the figure, 1 is the heater body, 2 is the air supply pipe, 3 is the exhaust pipe, 11
a is a discontinuous loop-shaped first slit, 11b is a second slit, and 12 to 16 are punched parts. In each figure, the same reference numerals indicate the same or corresponding parts.

Claims (1)

[Scope of utility model registration request] In the protective cover that protrudes from the back of the heater and maintains a distance from other objects, a first slit in the form of a discontinuous loop is provided surrounding a horizontally long punched part that serves as a passage for the wiring and piping of the heater. The punched part has a second slit that divides the punched part into a plurality of parts in the longitudinal direction of the punched part.
