Description

[Detailed explanation of the invention] This invention is a ventilation fan that can take in and exhaust air in one unit.
To provide a ventilation fan that can be easily installed even if the piping is separate pipes for intake and exhaust, or pipes separated into two layers.

Conventional ventilation fans include those shown in Figures 1 and 2.

That is, 1 is the main body of the ventilation fan with one side of the box open, 2 is the electric motor installed inside the main body 1, and 3 is the installation that is installed inside the main body 1 and divides the inside of the main body 1 into two with the electric motor 2 at the center. The plate 4 is a blade attached to both ends of the shaft of the electric motor 2, 5 is a blade casing that covers each blade 4, and 6a is arranged on one side of the main body 1 partitioned by the mounting plate 3. An intake blower, 6b is an exhaust blower disposed on the other side of the partitioned main body 1, and 7a is an intake blower 6a.
An intake port 7b provided on the side surface 1a of the main body 1 corresponding to the
Similarly, the side surface 1a of the main body 1 corresponding to the exhaust blower 6b
8a is an intake shutter installed corresponding to the intake lower a, 8b is an exhaust shutter similarly installed corresponding to the exhaust lower b, and 10a is connected to the intake lower a. An intake hole, 10b, is an exhaust hole that similarly communicates with the exhaust lower b, 11 is a cylindrical pipe holder, in which the intake and exhaust passages are separated and is installed corresponding to the intake hole 10a and the exhaust hole 10b, respectively, and 12a is the intake hole. hole 10
an intake shutter provided at a for guiding intake air to flow easily;
12b is an exhaust shutter that is similarly provided in the exhaust hole 10b and guides the exhaust; 13 is the intake hole 10 and the exhaust hole 1;
0b1 is a box-like attachment having an intake shutter 12a1 and an exhaust shutter 11b, and has a structure that divides intake and exhaust into two parts corresponding to the main body 1; 14 is an intake/exhaust double layer consisting of the pipe holder 11 and the attachment 13; It is a separate type passage connector.

In the conventional ventilation fan having such a configuration, the intake shutter 8
a and the exhaust shutter 8b are naturally necessary when the piping pipes are independent and separate pipes for intake and exhaust, respectively, and are connected without using the two-layer separation type passage connector 14, but when the piping pipes are two If the pipe is separated into layers, the intake and exhaust shutters 8a attached to the ventilation fan body 1
, 8b are unnecessary because the intake and exhaust shutters 12a and 12b are attached to the two-layer separated passage connector.

That is, when connecting with independent and separate pipes, it is necessary to attach the intake and exhaust shutters 8a and 8b to the main body 1, but this is not necessary with double-layer pipe piping, and dual intake and exhaust shutters are provided. This created an uneconomical situation.

The present invention was devised in view of the above-mentioned drawbacks of the conventional system, and is intended to provide a ventilation fan device that eliminates the wasteful economy of having dual intake shutters and dual exhaust shutters. .

An embodiment of the present invention will be described below based on FIG. 3.

Note that the same components are given the same reference numerals to simplify the explanation.

The ventilation fan device according to the present invention is almost the same as the conventional ventilation fan device described above, except that 18a is a cylindrical intake shutter frame that is provided corresponding to the intake lower a and has an intake shutter built in, and 18b is a cylindrical intake shutter frame that is provided corresponding to the intake lower a, and 18b is the exhaust lower shutter frame. A cylindrical exhaust shutter frame with a built-in exhaust shutter is provided corresponding to the intake shutter frame 18a and the exhaust shutter frame 18b.
are each covered with an attachment 13.

In the ventilation fan having such a configuration, an intake shutter frame and an exhaust shutter frame 18a, 18b are provided on the side surface 1a of the main body 1, and an attachment 13 to which a pipe holder 11 is attached is attached, that is, an intake/exhaust two-layer separated passage connector 14 is installed. By installing this, it is possible to eliminate the waste of having dual intake shutters and dual exhaust shutters.

Furthermore, piping work for two-layer separated pipes is also easily possible.

In addition, the intake hole and exhaust hole 10a, 10 of the attachment 13
Intake shutter and exhaust shutter 1 provided respectively in b
2a and 12b can be omitted, which is advantageous in terms of cost.

As explained above, according to the present invention, even if the piping is a separate pipe for intake and exhaust, or a pipe separated into two layers, it can be easily installed.

Furthermore, in the piping of the two-layer separation pipe, there is an advantage that an uneconomical double intake shutter and exhaust shutter configuration is not required.

Claims (1)

[Scope of utility model registration request] A blade and a blade casing are attached to both ends of the shaft of the motor, and one side is installed as an intake blower and the other side is installed as an exhaust blower inside the main body.Intake and exhaust ports are installed independently on one side of the main body to correspond to each blower. In a ventilation fan that has an intake shutter frame and an exhaust shutter frame attached to each mouth, and has an independent intake pipe and an exhaust pipe that can be detachably connected to each other, a two-layer intake/exhaust layer for connecting two-layer separated intake and exhaust pipes is used. A ventilation fan device characterized in that a separate passage connector is detachably provided on the main body around the intake port and the exhaust port.
