Description

[Detailed Description of the Invention] The present invention includes a can body for storing hot water heat-exchanged by the combustion heat of a burner, an exterior case in which the can body is housed, a lower end opening of the exterior case is covered, and the can The present invention relates to a hot water boiler equipped with a base that supports the body.

Conventionally, in this type of hot water boiler, in order to improve the ease of assembly, the can body 2, which is housed in the outer case 1, has its lower part connected to the outer case 1, as shown in FIG.
Simply fix it to the base 3 that covers the bottom opening of the
The upper part was left unfixed. However, in this configuration, the upper part of the can body 2 shakes laterally due to impact during transportation or dropping, and as a result,
There was a problem in that the pipes 4, 4' provided in the can body 2 came into contact with the outer case 1, causing the outer case 1 to deform.

Therefore, in order to prevent the upper part of the can body 2 from swinging laterally, the upper part of the can body 2 is fixed via a metal fitting 6 to an exterior top 5 that covers the upper opening of the exterior case 1, as shown in FIG. There is something like this. In this case, since the outer case 1 and the upper part of the can body 2 are securely fixed, the upper part of the can body 2 may sway laterally due to impact during transportation or dropping, and the outer case 1
However, since the upper part of the can body 2 must be fixed, the assembly work becomes very complicated, and depending on variations in the machining accuracy of the can body 2, the outer case 1 may be deformed. It had problems such as having to assemble it diagonally.

In view of the above-mentioned conventional problems, the present invention provides a hot water boiler that does not complicate assembly work and can prevent deformation of the exterior even if subjected to impact during transportation or dropping. The purpose is to

The basic structure of the present invention to achieve the above object is as follows: a can body for storing hot water heat exchanged by the combustion heat of a burner; In the hot water boiler, a reinforcing plate is attached to the upper opening of the outer case, and a slight gap is provided between the inner periphery of the reinforcing plate and the outer periphery of the can body. It is something that

With the above structure of the present invention, there is no need to fix the upper part of the can body to the outer case, making assembly of the outer case very easy. Even if the upper part shakes sideways, the upper part of the can will hit the inner periphery of the reinforcing plate attached to the upper opening of the outer case.
Since the container cannot swing further than that, deformation of the outer case due to the horizontal swing of the upper part of the can can be prevented.

An embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 3 shows the exterior structure of a hot water boiler according to an embodiment of the present invention. Reference numeral 11 denotes a base that covers the lower end opening of a square exterior case 12.
a base front 13 having a shape, and a base back 14 combined with this base front 13.
and a base leg 15. 16
4 is a reinforcing plate A attached to the upper opening of the outer case 12 with screws, and this reinforcing plate A16 has a substantially U-shape as shown in FIG. A portion 16a is formed.
17 is a substantially L-shaped reinforcing plate B attached to the flange portion 16a of the reinforcing plate A16;
17 and the reinforcing plate A16 constitute a substantially square portion 18, as shown in FIG.

Fig. 5 shows a cross-sectional view of the combination of the outer case and the can body. Reference numeral 19 is a can body that stores hot water that has been heat exchanged by the combustion heat of a burner (not shown). There is a slight gap 20 between the upper outer circumference and the inner circumference of the reinforcing plate A16 and reinforcing plate B17 attached to the upper end opening of the exterior case 12.
It has a meaning. With this configuration, the outer case 12 can move freely by the gap 20 with respect to the upper part of the can body 19, so assembly of the outer case 12 is easy, and the can body 19 can be easily assembled.
Since the upper part of the can body 19 does not move within a gap of 20 or more, even if the upper part of the can body 19 sways laterally due to impact during transportation or dropping, the lateral sway is prevented by the reinforcing plate A16.
As a result, deformation of the exterior case 12 due to lateral vibration of the upper part of the can body 19 is prevented.

FIG. 6 shows the state before the exterior top 21 is attached to the exterior case 12. The exterior top 21 has its side surface 21a in contact with the upper side surface 12a of the exterior case 12, and its rear surface 21b has a plurality of recesses. The upper rear surface 1 of the outer case 12 at the 22 part
2b and are fixed with screws, the exterior top 21 is attached to cover the upper end opening of the exterior case 12. in this case,
Since the reinforcing plate A16 is attached to the upper opening of the outer case 12, this reinforcing plate A16 serves as a reinforcement for the outer case 12. As a result, when assembling the outer case 12 and the outer top 21, screws cannot be used. This eliminates the problem of the outer case 12 being pushed and deformed, making it difficult to assemble.

Moreover, since the exterior top 21 is shaped so that its inner surface is supported by the exterior case 12 and the reinforcing plate A16, it is in a very strong fixed state.
As a result, even when subjected to shock during transportation or dropping,
The upper part of the exterior case 12 will no longer be deformed. Furthermore, a problem may arise in which the exterior case 12 resonates due to the vibration of a burner (not shown), but this problem can also be solved by installing the reinforcing plate A16 and the reinforcing plate B17 at the upper opening of the exterior case 11. This problem can be resolved by installing it.

In the above embodiment, the reinforcing plate A16 and the reinforcing plate B17 are attached to the upper opening of the rectangular outer case 12, but the above embodiment may also be applied to a round outer case. It has the same effect as the above.

As described above, according to the present invention, a reinforcing plate is attached to the upper opening of the outer case, and a slight gap is left between the inner periphery of the reinforcing plate and the outer periphery of the can body. , there is no need to fix the upper part of the can body to the outer case, and as a result, assembly of the outer case is much easier, and the upper part of the can body does not sway laterally due to impact during transportation or dropping. However, since the top of the can hits the inner circumference of the reinforcing plate attached to the top opening of the outer case and cannot swing any further, the outer case may be deformed due to the lateral swing of the top of the can. It has a simple structure and has various practical effects, such as being able to prevent damage.
