Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a combustion device such as a water heater,
In particular, the present invention relates to a rainproof plate which is provided in a casing arranged on the outer periphery of a combustion device installed outdoors and prevents raindrops from entering through a ventilation hole of the casing.

[0002]

2. Description of the Related Art Generally, the outer periphery of a combustion apparatus such as a water heater installed outdoors is covered with a casing, and a ventilation hole such as an intake hole is provided as a gallery in the casing, and the combustion air is used as the gallery. Was formed to be introduced through. In a combustion device equipped with such a casing, when installed outdoors, there is a problem that raindrops invade from the gallery when it rains, and in order to solve this problem, the inside of the casing corresponding to the gallery It is known that a partition plate (rainproof plate) is provided on the diver to bypass the combustion air flow path reaching the combustion device from the gallery above the partition plate to prevent raindrops intruding from the gallery from being applied to the main body of the combustion device. (For example, Japanese Patent Laid-Open No. 2-20
(See Japanese Patent No. 3111).

[0003]

However, in the casing of the above-mentioned conventional combustion apparatus, the gallery is opened at the lower position of the casing, and the combustion air that has entered from the gallery rises along the partition plate and partitions. After passing over the upper end of the plate, it descends along the partition plate and is supplied to the combustion device, so the combustion air flow path becomes longer,
There is a problem that intake resistance is increased and intake efficiency is reduced.

An object of the present invention is to provide a rainproof plate which can reduce air supply resistance and enhance the cooling effect inside the combustion apparatus.

[0005]

In order to achieve the above object, a rainproof plate according to the present invention has a front panel of a casing of a combustion apparatus which has an intake opening on a front surface and both side walls and has a drain hole at a lower portion thereof. It is a rain plate attached to the back of the
A vertically long ventilation hole is opened in the center, and a substantially L-shaped main windbreak plate is vertically divided and protrudes forward along the vertical side (long side) on the center side (inner side) of the ventilation hole. Corresponding to the position where the plate is cut, a substantially L-shaped auxiliary windbreak plate is projected forward on the outer vertical side (long side), and a rainwater guide inclined forward and downward is projected on the upper end. The edges and the bottom edge are aligned with both sides and the bottom edge of the front panel respectively, and the air intake port is formed in three directions of the front panel to improve the wind resistance performance, and the ventilation port of the rainproof plate from the intake port of the front panel. Since the distance to the mouth is long, the rainwater that flows in from the intake port does not flow into the ventilation port of the rainproof plate, the water dispersion is improved, and the noise is prevented because it has a double structure of the front panel and rainproof plate can do.

[0006]

Embodiments of the present invention will be described with reference to FIGS. 1 to 3, a front panel 1 of a casing that covers the outer periphery of a combustion apparatus installed outdoors is formed in a shallow box shape with an open rear, and a front surface located on the casing front side (outside) at the bottom of the box shape. A rear opening peripheral flange 11 and a rear opening peripheral flange 11 are joined together by a side wall 12, an intake long hole 13 is formed below the front surface 10, and a through hole 15 through which an exhaust pipe is penetrated is formed above, and ignition confirmation of a combustion device is confirmed at an intermediate position. A window 14 is provided, a plurality of intake ports 17 are opened in the left and right side walls 12, a plurality of drain holes 18 are formed in the lower side wall 12, and mounting slots 16 are formed in the upper and lower peripheral flanges 11. Is provided.

4 to 6, the rainproof plate 2 attached to the back side of the front panel 1 is bent rearward at both left and right ends of the main panel 20, and is attached to the mounting flange from the inclined wall 21.
22 is formed over the entire length in the vertical direction, the lower end of the main panel 20 extends downward and is bent rearward, and has a width that reaches the outer ends of the mounting flanges 22 on both sides.
23 are formed, and the mounting flange 22 and the lower flange 23
Corresponds to the peripheral flange 11 of the front panel 1, and the lower flange 23 is provided with a notch 31 corresponding to the mounting elongated hole 16 of the peripheral flange 11 at the lower end.

A mounting bracket 24 is provided at the upper end of the main panel 20 so as to be bent forward in a substantially L shape so as to come into contact with the back side of the front surface 10 of the front panel 1. The mounting bracket 24 is vertically provided substantially at the center of the main panel 20. A pair of vertically extending rectangular ventilation holes 25 are opened in parallel, and an opening 32 is provided at a position corresponding to the ignition confirmation window 14 of the front panel 1, and along the inner long sides of the rectangular ventilation holes 25, 25, Two pairs of upper and lower main windbreak plates, which are bent in a substantially L-shape, are projected from the front and bottom of the upper and lower main windbreak plates, which are separated from each other at a substantially central position. 2
An auxiliary windbreak plate 27, which is shorter than the distance between 6 and 26 and is bent in a substantially L-shape, is projected from the front, and low flanges 29 are provided above and below the auxiliary windbreak plate 27 so as to face the main windbreak plate 26. A low flange 28 is erected on the short side of the upper end of the rectangular ventilation port 25, and the main panel 20 at the front of the main windbreak plate 26 and the auxiliary windbreak plate 27 is provided.
The portion parallel to the main bracket 20 is located at substantially the same height as the portion of the mounting bracket 24 parallel to the main panel 20, and abuts on the back side of the front surface 10 of the front panel 1. Further, a rainwater guide 30 having a width wider than the distance between the outer sides of the rectangular ventilation holes 25, 25 is provided at the center of the upper end of the main panel 20 so as to be inclined forward and downward.

As shown in FIG. 7, the front panel 1
By attaching the rainproof plate 2 to the back side of the plate by spot welding or the like, a ventilation path is formed between the front panel 1 and the rainproof plate 2, and as shown by an arrow 5 in FIG. , For example, the air that has flowed in from the intake port 17 of the side wall 12 is split up and down by the auxiliary windbreak plate 27, hits the main windbreak plate 26, and is supplied to the combustion section (not shown) from the rectangular ventilation port 25, so that strong wind The influence of the above can be reduced, and by providing the intake long hole 13 of the front surface 10 and the intake ports 17 of the both side walls 12, the air intake performance can be improved because the intake openings are provided in three directions.

Further, as shown in FIG. 5, rainwater (arrow 4) flowing in from a through hole 15 or the like penetrating the exhaust pipe of the front panel 1 is flown to the back surface side of the front panel 1 by a rainwater guide 30 to form a rectangular shape. Without flowing into the vent hole 25, it flows down along the back surface of the front panel 1 and is drained to the outside from the drain hole 18.

[0011]

Since the present invention is configured as described above, the wind resistance is improved by forming the intake port in three directions of the front panel, and the intake port of the front panel to the ventilation port of the rainproof plate is improved. The rainwater flowing in from the intake port does not flow into the ventilation port of the rainproof plate because the distance to is longer, and the water sprinkling is improved, and the rainwater flowing in from above is prevented from flowing into the ventilation port. Since it has a double structure with the rainproof plate, noise can be prevented, and since the flow path from the intake port to the ventilation port is simple, the intake resistance can be reduced.
