Description

[Detailed description of the invention] [Industrial application field] This invention relates to the supply/exhaust structure of horizontal water heaters installed in high-rise apartment buildings, etc.

[Conventional technology]

In places with narrow indoor space, such as in high-rise apartment buildings, there is a desire to install the water heater horizontally using a hole in the wall. This allows normal combustion to occur not only when there is no wind, but also when there is wind.It also prevents rainwater from entering from the intake and exhaust pipes, and allows the direction of the exhaust gas to flow in a direction that is consistent with human daily life. must not be offensive or dangerous.

Therefore, as a conventional technique, for example, as shown in Japanese Utility Model Application Publication No. 57-190246, in an outdoor wall-mounted (vertical) water heater, the outer casing protrudes forward from the front cover. A rainproof/guidance plate is installed diagonally toward the outside of the device on the inside of the exhaust port, which is made up of a large number of oval openings perforated horizontally in the exhaust top, (hereinafter referred to as conventional example 1), or as shown in Japanese Utility Model Application Publication No. 56-36953,
In a vertical outdoor boiler, the upper exhaust port is equipped with a wind shield plate like an exhaust top, and the lower intake port is equipped with a waterproof cover above it to prevent rainwater from entering. 2) etc.

[The problem that the idea attempts to solve]

In Conventional Example 1 of the conventional technology, the rainproof guide plate is considerably narrower than the exhaust port and does not completely overlap with the exhaust port, so it is not particularly effective to prevent rainwater from entering from the front. Therefore, a separate rainproof plate is installed behind it.
Furthermore, even if the exhaust gas is to be discharged, the exhaust gas from the heat exchanger is bent twice due to the existence of the rainproof plate, and is only discharged from the top and bottom of the rainproof/guide plate toward the front and slightly upward. There are problems such as the possibility that the exhaust gas may directly hit the bodies of people who pass through common passages in apartment complexes, causing discomfort.
In Conventional Example 2, the exhaust port of the exhaust top is opened above and below the rear position from the front end face, and no wind shield is provided inside the exhaust port, so it prevents rainwater from entering and wind during strong winds. Problems such as reverse inflow and short circuits between intake and exhaust may occur.Furthermore, since the lower intake port prevention cover is formed to bulge rearward and has an intake opening on its lower surface, it protrudes considerably rearward from the main body casing, and the upper This combined with the protruding exhaust top of the equipment makes the equipment larger, and there are many disadvantages in terms of installation space, such as the need for a certain gap between the equipment and the rear wall when installing it. The dot was hot.

This idea was made in view of the problems of the conventional technology, and its purpose is to improve the water heater installed horizontally using a hole in the wall, not only when there is no wind, but also when there is wind. The present invention aims to provide a water heater supply/exhaust structure that allows normal combustion to occur, avoids the intrusion of rainwater from the supply/exhaust port, and allows the direction of exhaust gas to flow out in a way that does not cause discomfort or danger to people's daily lives. It is something to do.

[Means to solve the problem]

In order to solve the above-mentioned problems, this idea has a fixed internal structure that integrates functional parts such as a combustion chamber and a heat exchanger inside a rectangular outer shell that is inserted and fixed from the side into a hole for installation in a wall. In the water heater, the base end of a rectangular outer shell is opened and the tip thereof is closed, and an air supply port is bored at a position outside the wall surface on the lower surface of the rectangular outer shell. A plurality of exhaust ports are vertically bored in both corners of the end closing surface, and a wind shield plate having an F-shaped cross section is provided to overlap the exhaust ports with a gap inside the exhaust ports. They adopted technical means that are characterized by this.

[Effect]

Since the air supply port is bored at the bottom of the tip of the rectangular outer shell, the outer shell itself prevents rainwater from entering through the air supply port, and the exhaust port is blocked at the tip of the rectangular outer shell. A plurality of rows of holes are perforated in the vertical direction at both corners of the surface, and a wind shield plate with an F-shaped cross section is provided with a gap on the inner surface, overlapping the exhaust ports, so that the exhaust ports at both corners are The wind shield not only completely prevents the intrusion of rainwater and the backflow of wind during windy conditions, but also buffers the flow velocity of exhaust gas with the F-shaped wind shield and directs the exhaust flow diagonally from the exhaust port. This eliminates the possibility of direct contact with people walking in the hallway, eliminates the intrusion of outside air from the exhaust port when not in use, and also increases the product value because the interior cannot be directly seen.

[Effect of idea]

Since this invention has the above structure, the air supply port 1 is located outside the wall C surface on the lower surface of the rectangular outer shell A near the tip, and the air supply port 1 is covered by the rectangular outer shell A itself. Rainwater etc. do not enter through the air supply port 1, and a plurality of exhaust ports 2 are provided in a vertical row at both corners of the end closing surface of the rectangular outer body A. A wind shielding plate 3 with an F-shaped cross section is provided with a gap 21 inside the air outlet 2, completely overlapping the exhaust port 2, so that rainwater and the like can enter through the exhaust port 2 and backflow of wind during strong winds is prevented. The exhaust gas is completely blocked by the wind shield plate 3 to prevent deterioration of combustibility, and the exhaust gas is bypassed by the F-shaped wind shield plate 3 near the exit, thereby buffering its outflow speed. In addition, since the exhaust gas is discharged from both corners of the end closing surface of the rectangular outer body A with its outflow direction directed diagonally to the side, the exhaust gas is no longer blown directly onto people walking in the hallway (No. (See arrows a and a′ in Figure 2),
Since outside air does not enter through the exhaust port 2 when not in use, it also has the effect of preventing freezing, especially in winter, and the internal heat exchanger 7 is not directly visible because it is blocked by the wind shield plate 3, so it has commercial value. It can also be enhanced.

Therefore, it has a simple structure and has excellent effects that have not been seen before, so it has high practical value when applied to horizontal water heaters that are installed using holes in the walls, such as in high-rise apartment buildings.
