Description

[Detailed Description of the Invention] The present invention relates to an air intake structure in a hot water appliance, and aims to provide a hot water appliance with excellent wind resistance and combustibility.

The present invention will be specifically described below based on an embodiment shown in the drawings.

Reference numeral 1 denotes a main body that incorporates a heat exchanger 2, a burner 3, a gas mechanism section 4, etc., an exhaust port 5 is provided on the upper plate of the main body 1, and an exhaust pipe attached to a heat exchange case 6 is attached to the exhaust port 5. 7 is installed protrudingly,
A large number of air intake holes 8 are bored in the bottom plate of the main body 1.

Reference numeral 9 denotes a partition plate that divides the interior of the main body 1 into a combustion side and a gas mechanism side.

Reference numeral 10 is a box-shaped cylindrical body whose upper edge is attached to the outer wall of the bottom plate of the main body 1 and whose upper and lower surfaces are open.The lower edge is slightly bent inward to form an intake opening 1.
1, and the intake hole 8 is surrounded by the cylindrical body 10.

Reference numeral 12 is a substantially X-shaped dividing plate disposed below the cylindrical body 10 and formed by bending and joining a pair of band plates 14 to an inclined part 15 and a flat part 16, and connects the inclined part 15 to each corner of the intake opening 11. It extends from the bottom and intersects at the center, and is divided into four parts by the dividing plate 12 below the intake opening 11 in the front, back, right and left directions.

13 is a fixed leg attached to the bottom plate of the main body 1.

The present invention has the above configuration, and the combustion air of the burner 3 is supplied to the intake opening 11 of the cylindrical body 10. Air is supplied to the bottom plate of the main body 1 (through L8), but when there is wind, for example, A
When the wind blows from the direction, the dividing plate 12 blocks the wind and prevents the generation of negative pressure near the intake hole 8 due to the wind blowing through. At this time, the wind is rectified in the horizontal direction by the newly curved lower edge of the cylinder body 10, and eventually rises at the intersection of the dividing plates 12, and the air is drawn into the cylinder body 10. It is guided into the cylindrical body 10 through the opening 11.

At this time, the upper edge of the box-shaped cylinder 10 is attached to the bottom wall, and the lower edge is slightly bent inward, so there is no risk of the wind entering the cylinder 10 flowing backward.

The force of the wind guided into the cylindrical body 10 is weakened internally, and when it passes through the intake hole 8, it is also rectified and supplied into the main body 1 as combustion air of the burner 3.

As described above, the present invention provides a box-shaped cylindrical body with an intake opening formed by bending the lower edge slightly inward on the main body bottom plate with an intake hole, and Since there are approximately X-shaped dividing plates that extend from below each corner of the intake opening and intersect at the center, the air passing under the bottom plate is guided and converged into the burner area without escaping, allowing the air to flow through the air needed for combustion. It is possible to secure a sufficient amount of air, and even in windy conditions, the air supplied into the main body 1 is rectified and controlled to have an appropriate force, and furthermore, the air supplied into the main body 1 is rectified and controlled to have an appropriate force. Since the above-mentioned effect is exhibited even in the presence of wind, there are no restrictions on the installation direction of the water heater, and the water heater is structurally simple and easy to manufacture.
