Description

[Detailed description of the invention]

[001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an indoor ventilation device having two intake ports and blowing air from one of the intake ports to generate an intake force to the other intake port.

[002]

2. Description of the Related Art Conventionally, there has been a ventilator which has one intake port and directly generates an intake force at the intake port by rotating a ventilation fan installed at the exhaust port.

[003]

[Problems to be Solved by the Invention] This has the following drawbacks. (B) Since the smoke that is going to be discharged to the outside is directly sucked in by the ventilation fan, it is inevitable that the ventilation fan is contaminated by the oil mixed in the smoke. (B) That it was necessary to regularly clean the ventilation fan,
Ventilation fans with complicated shapes could not be adopted to facilitate the cleaning. (C) Due to the structure of the device, there was no choice but to install a ventilation fan at the exhaust port, and there were many restrictions on the shape and installation location of the device. The present invention has been made to eliminate these drawbacks.

[004]

Means for Solving the Problems Exhaust air in which a smoke intake port B (5) is attached to one side of a cylinder A (1) to which a blower intake port A (3) is attached, and the other end is obliquely cut Mouth B
The diagonally cut side of the cylinder B (2) having (6) is inserted at a right angle, and the air blower is installed on the side of the air blow inlet A (3). The present invention is a ventilation device configured as described above.

[0095]

When the air is sent from the air blower installed on the side of the air intake port A (3) toward the exhaust port A (4), the exhaust port B
(6) The air pressure in the vicinity decreases and suction force is generated at the smoke intake port B (5). By utilizing this suction force, the smoke in the vicinity of the smoke intake port B (5) is sucked in and discharged from the exhaust port A (4), so that indoor ventilation can be performed.

[0096]

EXAMPLES Examples of the present invention will be described below. (A) An air blower (7) inside the air blow inlet A (3) of the cylinder A (1) having the air blow inlet A (3) attached to one side.
Is installed. (B) At the center of the lower part of the cylinder A (1), the smoke intake port B
(5) is attached to one side, and the other end of the cylinder B (2) having an exhaust port B (6) whose end is cut obliquely is provided with a pointed side of the end of the obliquely cut end B (3) for blowing air. ) Side and insert at a right angle and fix. According to the present invention, when the air is sent from the air blower (7) installed inside the air intake A (3) for air blow to the air outlet A (4), the air pressure near the air outlet B (6) is changed. The lowering causes a function of sucking smoke near the smoke intake port B (5), and the smoke sucked from the smoke intake port B (5) does not come into contact with the blower device (7) and the exhaust port A (7).
It will be discharged from (4).

[0097]

[Advantages of the Invention] By dividing the air intake port for blowing air and the air intake port for smoke, it becomes possible to ventilate smoke without directly contacting the ventilation fan (the air blower in this invention), and a ventilation fan using oil ( Since the air blower) does not become dirty, it is possible to use an air blower of any complicated shape without considering cleaning or the like. In addition, because of the configuration of the device, a ventilation fan (a fan device in the present invention)
Since it does not need to be installed at the exhaust port, the exhaust port can be installed at any place. Further, since there is no particular restriction on the installation location of the air intake port for ventilation, it is possible to ventilate using natural wind by installing it outdoors.

Claims (1)

(57) [Scope of utility model registration request] 1. A smoke intake port B (5) is attached to one side of a cylinder A (1) having a blower intake port A (3) attached to one side thereof, and an exhaust port B (of which the other end is cut obliquely). A ventilation device in which a diagonally cut side of a cylinder B (2) having 6) is inserted at a right angle and a blower device (7) is installed on the side of a blower intake port A (3).
