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.

Conventional hot water boilers of this type are constructed as shown in Fig. 1. That is, 1 is an outer case, 2 is a base attached to the lower end opening of the outer case 1, and a boiler body 3 is attached to this base 2. 4 is a burner attached to the boiler body 3, and 5 is an outer top that closes the upper end opening of the outer case 1. In addition, hot water pipes 6 and water supply pipes 7 are provided at the upper and lower parts of the boiler body 3, and these hot water pipes 6 and water supply pipes 7 penetrate holes 8 and 9 provided in the outer case 1, respectively, and protrude outward. 10 is a louver provided on the outer case 1, and this louver 10 is provided to take in outside air into the outer case 1. In addition, hot water boilers are often installed outdoors, and therefore, in the past, as a measure to prevent rainwater from entering the outer case 1 when installed outdoors, a separate cover 11 was provided to cover the louvers 10 from above to prevent rainwater from entering the outer case 1 through the louvers 10, which was expensive and did not look very good. The base 2 is a material that covers the lower end opening of the outer case 1,
The plate thickness and shape needed to be sufficient to support the weight of the entire product, and because it was close to the ground, it needed to be plated or painted to prevent rust, making it extremely costly.

In view of the above-mentioned conventional problems, the present invention provides a hot water boiler in which the outer case has a clean appearance, does not allow rats to enter through the air intake port, and is inexpensive in terms of cost. The purpose is to

The present invention to achieve the above object includes a can body that stores hot water that has been heat exchanged by the combustion heat of a burner;
It includes an exterior case with the can body inside, and a base provided at the lower end opening of the exterior case, the base having a convex portion that comes into contact with the installation surface, and the base having a protrusion that contacts the lower end opening of the exterior case other than the can body. It consists of a base front that covers, a base back that is combined with the base front to fix the exterior case, and base legs that directly support the can body. The entrance is sized so that mice cannot pass through.

By adopting the above structure of the present invention, there is no need to provide an extra opening in the outer case for air intake, and there is no need to take measures to prevent rainwater from entering, so the outer case has a clean appearance. In addition, since the air intake port is provided in the base that covers the bottom opening of the exterior case, there is no need to take any special measures to prevent rainwater from entering.Furthermore, the only parts of the base that require strength are the base legs, and the base front Since it is only necessary to cover the bottom opening of the exterior case other than the can body, it can be obtained at low cost.Moreover, the air intake port is made large enough to prevent rats from passing through the exterior case. This also solves the problem of penetrating into the case and tearing off electrical wiring.

An embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 2 shows the exterior structure of a hot water boiler according to an embodiment of the present invention. Reference numeral 21 denotes a base that covers the lower end opening of the exterior case 22, and this base 21 has a convex portion 23a that comes into contact with the installation surface. It is composed of a base front 23, a base bag 24 combined with the base front 23, and base legs 25. The base front 23 and the base back 24 form a substantially rectangular frame, and a plurality of base legs 25 are fixed to the bottom of the base back 24, as shown in FIG. Further, when this hot water boiler is installed on the floor surface, the base legs 25 and the convex portions 23a of the base front 23 are in contact with the floor surface.

FIG. 4 is a plan view showing the state in which the can body is attached to the base, and 26 is a can body that stores hot water that has been heat exchanged by the combustion heat of a burner (not shown).
A plurality of protrusions 26a are formed outwardly on the bottom of the base leg 6, and these protrusions 26a are connected to the plurality of base legs 2.
5, and the bottom portion is supported by a flange portion 24a projecting inwardly from the base bag 24. The base front 23, base back 24, base legs 25, and can body 26 are assembled with gaps 27, 28, and 29 shown by diagonal lines, respectively, and the base front 23 is provided with an air intake port 30 consisting of a long hole. It is set up. In this case, holes of various shapes (not shown) may be provided in the bottom of the base bag 24 and the can body 26 as necessary. In addition, the gaps 27, 28, 29 and the air intake port 30 have a maximum width of a size that cannot allow a mouse to pass through, and the maximum width is 8 mm.
and has set standards.

As is clear from the above configuration, since the exterior case 22 does not have any extra openings for air intake, there is no need to take any particular measures to prevent rainwater from entering. Since the air intake port 30 is provided in the base 21 that covers the lower end opening of the outer case 22, there is no need to take special measures to prevent rainwater from entering, and the cost is also reduced. In the base 21, only the convex portion 23a provided on the base front 23 and the base legs 25 are in contact with the floor surface. It is only necessary to apply anti-rust treatment to the parts, such as plating or painting, and as a result, the cost of surface treatment can be reduced. Also, the base front 2 that constitutes the base 21
3 and the base bag 24, compared to conventional materials, the part located at the bottom of the can body 26 is unnecessary, and the can body 26, which accounts for most of the weight of the product, is configured to be supported by the base legs 25. Therefore, only the base legs 25 need to be strengthened, and as a result, the other base parts, namely the base front 23 and the base back 24, can be made thinner, reducing the cost of the base as a whole. It is something that can be done.

In addition, the bottom of the can body 26 tends to become very hot due to the influence of heat in the combustion chamber located above the inner bottom of the can body 26, and there is a high possibility that it will lead to danger such as flames, so it is generally not necessary to shield the bottom of the can body 26. A heat shield member (not shown) is provided between the bottom of the can body 26 and the floor for heat protection, but in one embodiment of the present invention, an air intake port 30 is provided in the base 21.
, the air flow between the bottom of the can body 26 and the floor increases, and as a result, it is possible to prevent the temperature of the floor from rising excessively.

As described above, according to the present invention, a base is provided at the lower end opening of the outer case, and this base is combined with the base front that covers the lower end opening of the outer case other than the can body, and the base front is combined with the base front to cover the lower end opening of the outer case. Since it is composed of a fixed base bag and base legs that directly support the can body, only the base legs are required to be strong.
Furthermore, since the base front does not just cover anything other than the can body, it is small and extremely inexpensive. Moreover, since the air intake port is sized so that mice cannot pass through, the problem of mice entering the exterior case and tearing off electrical wiring etc. can be eliminated.
