Description

  The present invention relates to a supply / exhaust system for a so-called forced supply / exhaust type (FF type) combustion device that forcibly sucks combustion air from the outside and forcibly discharges combustion exhaust to the outside.

As shown in Patent Document 1, a supply / exhaust pipe of a forced supply / exhaust combustion apparatus has a double pipe structure that sucks combustion air from an outer pipe and discharges combustion exhaust from an inner pipe. The air supply / exhaust top (supply / exhaust port) is attached to the end of the supply / exhaust pipe that extends horizontally through the outer wall of the building and extends horizontally, taking air into the pipe from the side and exhausting it. Is discharged horizontally.
In this way, the reason for the horizontal orientation is that the fan is forced to supply and exhaust air, so there is no need to be aware of the drafting action, the pressure loss is reduced to reduce the fan load, Since the extension of the exhaust pipe is short, there is no cost, and if the supply / exhaust top is installed facing upward, rainwater or drain water may enter the supply / exhaust pipe and cause troubles. This is the reason.

  For this reason, many forced air supply / exhaust combustion appliances have a horizontal supply / exhaust top in practical use, but when the neighbor is approaching, the supply / exhaust top is directed toward the neighbor. If this is not possible, install the supply / exhaust pipe in the other direction in the room and project the supply / exhaust top from another direction. Sometimes you have to give up.

  However, forced supply / exhaust type combustion equipment is superior in safety because it does not use any indoor air and does not emit indoors. Therefore, there is an increasing demand for a supply / exhaust system that can solve the problem that a forced supply / exhaust type combustion device cannot be installed.

As a result of intensive research and experiments from this viewpoint, the present inventor has effectively treated rainwater and drain water to prevent troubles, so that the top of the air supply / exhaust top is located above the roof. We have completed a vertical air supply / exhaust system that can be attached to the system.
Furthermore, when the supply / exhaust top is faced upward, it will normally be installed on the roof, so it will be necessary to devise a way to treat the part that protrudes from the roof, including rain. I have come up with an effective means for this point, so I would like to propose it here.
Furthermore, when drain water is generated in the peripheral surface of the exhaust pipe in the supply / exhaust pipe installed in the eaves, an effective means for draining this drain water out of the supply pipe by the force of gravity has been completed. So we propose here.

In order to achieve the above object, in the invention described in claim 1, the roof of the building is penetrated in the eaves direction to construct the supply / exhaust pipe of the combustion device of the forced supply / exhaust system, and the extension extended on the roof In a vertical air supply / exhaust system in which an air supply top is mounted on the air supply / exhaust pipe, and an exhaust top is further mounted thereon,
A roof penetrating member for attaching the air supply / exhaust pipe vertically to the roof;
An air supply top connected to an air supply / exhaust pipe of the roof penetrating member;
The lower end of the exhaust pipe is connected to the exhaust pipe on the top of the supply air, and the exhaust port formed at the upper end of the exhaust pipe is formed with an exhaust slit at the lower part of the peripheral side wall, and is surrounded by the peripheral side wall, the roof, and the bottom plate. An exhaust top located in an exhaust chamber of a
A rain cover attached to the exhaust pipe so as to cover an air inlet opening at the upper end of the air supply pipe of the air supply top and to form an air inflow path inside;
An umbrella-shaped top cover attached to the exhaust pipe of the exhaust top, below the exhaust slit of the exhaust top;
Is provided.

  Furthermore, in the invention described in claim 2, in the vertical air supply / exhaust system according to claim 1, male screws are respectively formed on and joined to the upper and lower ends of the exhaust pipe in the supply top. A female screw is formed on the roof penetrating member and the exhaust pipe on the exhaust top side.

  Furthermore, in the invention according to claim 3, in the vertical air supply / exhaust system according to claim 1, the roof penetrating member has a double-pipe structure supply / exhaust pipe inserted into the supply pipe at the center. A rectangular adjustment member formed by mounting and forming a side plate in the front-rear direction in an arc shape and the side plate in the front-rear direction match the curvature of the arc of the side plate of the adjustment member so that the side plate of the adjustment member can be crowned A rectangular receiving frame member formed as described above, and an upper opening is formed in a square shape so that the receiving frame member can be attached, and a mounting frame for a roof surface inclined at the bottom is formed. And a base member having a configuration in which the inside is opened in a square shape.

  Further, according to a fourth aspect of the present invention, in the vertical air supply / exhaust system according to the first aspect, the air supply top has a double pipe structure in which an exhaust pipe is inserted into the air supply pipe. A male / female joint receiving port is formed at the lower end of the top air supply pipe, and male screws are formed at the upper and lower ends of the exhaust pipe, respectively. Furthermore, a rain cover having a face-down shape is attached to the lower end of the male screw, and the air supply port formed at the upper end of the air supply pipe opens into the rain cover. It is characterized by that.

  Furthermore, in the invention according to claim 5, in the vertical air supply / exhaust system according to claim 1, the exhaust top is a female screw in which a male screw at an upper end of an exhaust pipe of the air supply top is screwed to a lower end. The exhaust port formed at the upper end of the exhaust pipe forms a roof with a triangular cross section at the upper part of the peripheral side wall that changes in diameter from the periphery of the bottom plate upward, and the exhaust slit at the lower part of the peripheral side wall A top cover having an umbrella-shaped spread and having a larger diameter than the rain cover of the air supply top is attached to the bottom of the exhaust chamber. It is characterized by.

Further, according to a sixth aspect of the present invention, the vertical air supply / exhaust system according to the first aspect has a double pipe structure in which an exhaust pipe is inserted into an air supply pipe. The drain water induction step portion inclined to one side is formed, the drain port is formed at the lowest position of the drain water induction step portion, and the drain port is inclined so as to penetrate through the air supply pipe to the outside. A drain water drainage member having a structure with a drain discharge pipe attached thereto is connected to the lowermost part of a supply / exhaust pipe piped in the vertical direction.
By this invention, even if drain water is generated in the supply / exhaust pipe, it can be drained outside the pipe at the bottom of the supply / exhaust pipe in the saddle direction. Never become.

1. Since the air supply / exhaust pipe can be extended in the saddle direction and the air supply / exhaust top can be installed on the roof, an air supply / exhaust system can be constructed without paying attention to the proximity of the neighboring house.
2. By taking perfect measures against rain and drain water, rain water and drain water will not enter the supply and exhaust pipes and cause trouble.
3. In the roof penetration, it can be adjusted so that the air supply and exhaust pipes are kept vertical according to the inclination of the roof, so there is no need to prepare roof penetration members with different standards for each site.
4). Since male screws are formed on the top and bottom of the exhaust pipe in the air supply top and joined to the female screw of the exhaust pipe on the exhaust top side, rainwater and drain water transmitted from the exhaust top side is supplied to the supply top. Does not flow into the
