Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air intake device for a small boat which efficiently takes in air by utilizing wind generated by the traveling of the boat.

[0002]

2. Description of the Related Art Heretofore, there has been known an intake device for a small boat which glides on water at high speed to perform various movements such as sudden turning and sudden stopping. In boats that perform such movements, it is necessary to form an air intake port to supply air to the engine, etc. mounted inside the hull, and this air supply port is conventionally opened on the deck in front of the operation handle. In addition to forming the part, a structure is adopted in which a water blocking means for blocking water that has entered with the air is provided inside the opening.

[0003]

In the above structure, since the air inlet and the water shut-off means are provided on the front side of the operation handle, the degree of freedom in the design of the portion is restricted, and for example, for checking the engine. There is a problem that the degree of freedom in design such as installing an openable hatch cover is limited. In addition, it is preferable that the air intake is sufficient and water is not allowed to enter as much as possible.Therefore, it is necessary to install the air intake at a position as high as possible on the hull. It was desired to develop the installation position and installation structure.

The present invention has been made in order to solve the above-mentioned conventional drawbacks, and provides an intake system for a small vessel in which air is sufficiently taken in and the degree of freedom in design is not restricted. The purpose is.

[0005]

According to the present invention, while a rearview mirror is held on the front side of a driver's seat, a pair of left and right mirror cases protruding from a hull are provided, and an air intake is formed in the mirror case. The interior space of the mirror case communicates with the interior space of the ship.

It is preferable to connect an air supply pipe, which is guided to a predetermined position in the ship, to the mirror case. Further, it is preferable to connect a drain pipe to the mirror case for discharging water that has entered the mirror case to the outside of the ship. Further, it is preferable that the mirror case has the air intake port formed in a portion that receives wind when the ship is traveling.

[0007]

In the above construction, air is sucked into the ship from the air intake port of the mirror case due to the calendar function of the engine, and this air is supplied to the bow space or the side space of the engine. And since this air intake port is formed in a mirror case installed at a high position of the hull and at a position where wind easily hits when sailing, it is difficult for water to enter,
Air can be taken in sufficiently. In addition, in order to form the air intake in the compact configuration mirror case,
It is easier to process the air intake means than when it is formed on a hull member that is a large member, and since the structure of the air intake means is at each end, the degree of freedom in designing the hull structure is not restricted. There are also advantages. Further, by connecting the drain pipe to the mirror case, when water enters together with air through the air intake port, it can be easily discharged through the drain pipe.

In the above structure, when the hull 100 travels, air is sucked from the air intake 81 of the mirror case 8 due to the intake action of the engine, and this air passes through the opening 131 and the air supply pipe 83, and the air of the engine 1 flows. Supplied to the side space. Since the air supply pipe 83 is opened in the vicinity of the engine 1 where negative pressure due to the intake action of the engine is likely to act, air is mainly sucked through the air supply pipe 83. In the case of this embodiment, the air intake port 81 is open toward the front, and air is sent from the air intake port 81 to the inboard space by the traveling of the ship in order to receive the wind when the ship is traveling. Can be taken in smoothly. The air exhaust pipe 82 is used to introduce air into the ship or exhaust the air in the ship.

When water enters with the air through the air intake port 81, the water does not enter the air supply pipe 85 which is open at the upper position in the case 86, and the case 8
It is discharged through a drain pipe 84 that is open at the bottom of 6. The air supply pipes 82 and 83 may not be provided, and the internal space 800 of the mirror case 8 may simply be communicated with the inboard space where the engine 1 and the like are installed.

Since the air intake port 81 is formed in the mirror case 8 installed at a high position of the hull 100 and at a position where wind easily hits when sailing, it is difficult for water to enter and air is sufficient. It has the advantage that it can be incorporated into Further, since the air intake port 81 is formed in the compact mirror case 8, it is easier to process as compared with the case where it is formed in a large hull member,
Further, since the structure of the air intake means is simple, there is an advantage that the degree of freedom in designing the hull structure is not restricted.

[0021]

As described above, according to the present invention, air is sucked into the ship from the air intake port of the mirror case by the intake action of the engine, and this air is supplied to the bow space or the side space of the engine. To be done. And since this air intake port is formed in the mirror case installed at a high position of the hull and where the wind from the sailing easily hits, it is difficult for water to enter and air can be taken in sufficiently. There is an advantage that you can. In addition, since the air intake is formed in the compact mirror case, the hull intake means can be processed more easily than when it is formed on a large hull member, and the air intake means is simple in construction. Therefore, there is also an advantage that the degree of freedom in designing the hull structure is not restricted. Further, by connecting the drain pipe to the mirror case, when water enters together with air through the air intake port, it can be easily discharged through the drain pipe.
