Abstract

A ventilator unit includes both internal and external flaps 5, 6 which are opened and closed by means of a low voltage actuator/s and linkage system. The ventilator is activated by natural gas and carbon monoxide sensors 1, 2 which are fitted to the printed circuit board 3, mounted behind the front panel 4. Also upon activation, an alarm 9 sounds and LED light 10 and/or 11 will flash according to which gas has been detected. A rechargeable battery pack 17 powers all electrical aspects of the ventilator, and is charged by one or more solar panels 18 fitted to the external flap 6. The front panel features control buttons for reset 12 and test 13 and LED lights to indicate fault 14, battery condition 15 and system on 16.

Description

I VENT
This invention relates to a safety device, which is intended to evacuate dangerous levels of natural gas and carbon monoxide which may build up in a room / house through leakage etc. or poor gas combustion.
Natural gas and carbon monoxide are both lighter than air and therefore if left uncontrolled where combustion is attempting to take place due to a fault, these gases will rise towards the ceiling of a room. The room will gradually fill up; any source of ignition could spark an explosion, or persons breathing carbon monoxide flumes, could lead to very serious consequences, or even death. To help overcome this problem, the present invention proposes to be a ventilator, wall mounted just below ceiling level. It incorporates an internal opening flap and an external opening flap. These flaps open simultaneously when sensors in the vent detect gas or carbon monoxide, so venting them outside.
When activated and opened, dangerous levels of gas will not be able to build up in the room.
This is a totally independent unit as it is solar and battery powered. It is easily installed anywhere, especially new build.
It will continue to work during a mains power failure.
An example of the invention will now be described by referring to the accompanying drawings: * Figure 1 shows an exploded view of the I vent, * Figure 2 shows the I vent in the opened position, * Figure 3 shows the cross section view of the I vent through the wall.
The I vent will constantly monitor for any potentially dangerous gas levels via two sensors (fig 1), l&2 mounted on the control board (PCB) (fig 1), 3.
This PCB is mounted to the back of the internal frame, (fig 1), 4, which provides user access to the controls and has the sensor slots. When the sensors are triggered by the gases, the PCB will activate one or more actuators (figi, 19) which act upon the internal flap (figi, 5) and the external flap (figl, 6), and opens them.
Both flaps are hinge mounted, one to the external mounting frame (figi), 7 and one to the internal mounting frame/control panel (fig 1), 4. Both frames contain the ends of the vent ducting, (figi), 8, to complete the build of the vent.
Upon closing, the actuator/s reverses, closing both flaps.
As the vent is opening, a beeper (fig2), 9, will sound an alarm, and an LED will flash to indicate which gas is present. Two LED's (fig2),1O&1 l,will flash if both gases are present.
A reset button (fig2), 12, when pressed, will close the I vent, which will in turn shut the beeper and the LED's off, to resume normal monitoring.
There is a test button (fig2), 13, which when pressed, will open the flaps, sound the beeper and check that all LED's light up. Other LED's include a fault indicator (fig 1), 14, a battery low indicator (figi), 15, and a system on' indicator, (fig 1) 16.
Power for this unit is provided by a rechargeable battery pack (figi), 17.
This battery pack is trickle charged from a solar panel (fig 1), 18, which is mounted on the outside flap (fig 1), 6.
The PCB function list is as follows: 1/ POWER a! To allow the battery pack to be constantly trickle charged by the solar panel.
b/ To constantly monitor the sensing system using battery power.
c/ LED to indicate battery condition; flashing red for low, constant red for battery change when it is nearing the end of its' life.
d/ A single press of the reset button will switch the unit on, with green LED.
e/ A prolonged pressing of the reset button will switch the unit off.
2 OPERATION a/ To power two gas sensors, one for natural gas, the other for carbon monoxide.
b/ To power the actuator/s when one or both sensors (natural gas or carbon monoxide are activated.
cf Current limit control' at fuily open and closed vent positions, to switch the power off to the actuator, thus preventing any over-run and subsequent damage.
d To activate an alarm sound, (beep).
e/ To activate an alarm flashing LED, or both LED's if both gases are present.
fJ To have a reset button, which will close the vent, and turn off the alarm sound and flashing LED'(s).
g/ The reset button must not operate if the harmful gases are still present when attempting to close the vent.
h/ To have a test button, to allow the user to open and test the overall operation of the vent, independent of any harmful gasses. This will also allow the user to access the inside of the vent for any service issues, battery replacement etc. j/ To have a fault indicator LED which will glow red should a fault occur when charging the battery, or with monitoring problems etc.
