Description
OPENING MECHANISM FOR A VENTILATOR
The present invention relates to an opening mechanism for a ventilator or skylight. In particular, the present invention relates to an opening mechanism for a ventilator or skylight which is sensitive to temperature changes and/or activiated by the onset of rain.
According to the present invention there is provided a means for opening or closing a ventilation opening between an open position and a closed position, including in combination a temperature sensing means capable of causing the opening and closing means to open when the temperature within the building rises above a predetermined level, and to close when the temperature within the building falls below a predetermined level, and a rain detection means capable of causing the closing means to close on the onset of rain.
There is further provided control means to actuate means for opening or closing the ventilation opening, the control means being responsive both to the temperature sensing means and to the rain detection means.
The means for opening and closing the ventilation opening may be actuated in the sense to open the ventilation opening when the temperature sensing means detects a predetermined level of temperature within the building and the rain detection means detects no presence of rain.
The control means includes a control box having dial means for setting the temperature at which the actuating means for opening and closing the ventilation opening is operative, and the control box may include means for manually actuating the means for opening or closing of the ventilator.
The means for opening and closing the ventilation opening includes an electrically operated rack and pinion system and further includes means for closing the ventilation opening when the rain sensing means detects the presence of rain.
Preferably the rain detecting means includes an exposed electric circuit having a break therein, whereby a drop of rain can complete the circuit in order to cause closure of the ventilation opening.
Apparatus according to claims 7, 8? wherein The rain detecting means may include a plurality of copper conductors separate from one another and mounted on a plastic base, and may further include a heater capable of evaporating any residual water remaining thereon after cessation of rain.
The rain-detecting means may have its copper conductors mounted at an angle to the horizontal, and is preferably mounted outside the building.
The control system may effect only partial closure of the ventilator when the temperature within the building is at or above a predetermined level and rainfall is detected by the rain sensor.
The purpose of the present invention is to open a vent, window, orifice to allow ventilation in for example conservatories etc. One of the problems with glass conservatories is that the sun causes the temperature of the air within the conservatory to rise rapidly because of the effect of the glass. As a result conservatories can often feel stuffy and hot, the air within the conservatories reaching high temperatures. The apparatus of the present invention provides a suitable manner of reducing the temperature automatically, providing adequate ventilation throughout the conservatory and at the same time once the temperaturewithin the conservatory drops, the thermostat detects such a drop in temperature and causes the apparatus to close the ventilator. In addiction a further problem is the onset of rain.
It is preferred that the present invention includes a rain detector such that the rain drops act on an exposed electric circuit causing electrical conductivity such that the circuit is completed and the ventilator mechanism is activated to close the ventilator. It is preferred that the rain detection means is connected into the operating circuit such that the onset of rain will cause the ventilator to close whatever the temperature
Alternatively the control mechanism can be adjusted such that the onset of rain causes the ventilator to close to a position whereby rain does not enter the conservatory yet ventilation can continue to take place whilst the temperature is high within the conservatory.
The operating means for the ventilator is a conventional linear extending device such as a piston operated on a rack and pinion system. Alternatively the piston may be operated pneumatically or hydraulically.
The rain detection means is preferably an exposed copper circuit having a break whereby a drop of rain would cause the circuit to be completed thereby operating the opening and closing means. It is preferred that the rain detection means also includes a heating device to facilitate a faster response time. Thus once rain stops falling the small heater causes the water on the sensing device to evaporate breaking the circuit. In addition, during cold weather the small heater prevents undesired operation by ice or snow.
In addition to the temperature sensing means which is preferably a thermostat the present invention preferably includes a manual override allowing an operator to open or close the orifice as desired.
The present invention will be further described, by way of example only, with reference to the accompanying drawings in which:
Figure 1 shows the general arrangement of the present invention
Figure 2 shows the schematic diagram of the operation of the present invention
Referring to Figure 1, the present invention will be described with reference to the ventilation of a conservatory. A Conservatory 10 having glass panel sides and a glass ridged roof 12 has two ventilation windows 14 and 16. The ventilation widows 14 and 16 are pivoted by means of hinges 18 and 20. Stays 22 and 24 which extend from electric motors 26 and 28 on a rack and pinion arrangement cause the windows 14 and 16 to open or close pivotally along hinges 18 and 20. The stays 22 and 24, are operated by electric motors 26 and 28 which are connected by means of control wires 30 to a control box 32.
The control box has a control means allowing the windows to be opened closed or set to an automatic position. The control box is supplied by a power source 34. A rain detector 36 is positioned on the roof qf the conservatory 10 along the ridge line 12. The rain detector is a series of copper conductors which are electrically connected via raindrops as they fall on the rain detector. The rain detector 36 is connected by means of control wires to the control box 32. As the circuit is completed the stays 22 and 24 are adjusted to a closed position by means of electric motors 26 and 28. Once the rain evaporates te connection in the rain detector 36 is broken allowing the electric motors to cause the stays to open the ventilating windows 14 and 16.
Referring now to Figure 2, a schematic diagram of a single ventilator opening of the present invention is now shown. A ventilation window 14 has hinges 18 and a stay 22 extending from an electric motor 26. The electric motor 26 is connected by means of control wires 30 to contol box 32 having a power source 34 generally designated as P. A rain detector 36 is positioned on the roof and has a series of two interdigited copper conductors 38 and 40 separated from one another physically and mounted on a plastic base 42.
The space between the interdigited portions 38 and 40 may be variable but in order to detect drops of rain needs to be approximately 1 to 2 mm. The rain detector 36 is connected by control wires 44 to the control box 32. An optional heater is contained in a plastic housing beneath the base 42 of the rain detector. The heater derives its power from the control wire 44 and is a low power heater generally providing a temperature of up to 300C in the summer and up to 50C in the winter. This allows the rain detector to be sensitive to drops of rain but also sensitive to the cessation of precipitation such as rain or snow. Once rain ceases, the water will be evaporated breaking the circuit between the interdigited portions 38 and 40.In a similiar manner once snow has ceased falling, the temperature of 50 being a preferred minimum temperature, causes the snow to melt and water to evaporate, once again breaking the connection between the interdigited portions 38 and 40.
The control box 32 may be connected to a room thermostat 46. The control box 32 may have a number of settings. For example it may include a closed position, a stop position, an open position and an automatic position.
The automatic position is operated by thermostat 46. A temperature selection knob 48 is provided to allow selection of room temperature between 100C and 60 C.
In operation when the control is set at the closed position the electric motor causes the stay 22 to retract causing the ventilator 14 to close. When the selector is set to an open position the electric motor 26 causes the stay to extend opening the ventilator. By setting the knob to a stop position an intermediate selection can be obtained between open and closed. Selecting the automatic selection incorporates the thermostat 46 such that a temperature can be selected between the desired operating range lO0C to 6O0C. On attaining the temperature the ventilator will open. Once the thermostat drops below the desired temperature, the ventilator will close.If the ventilator is in an open position the rain detector 36 will come into operation such that a drop of rain falling between the interdigited leaves 38 and 40 closes the connection and causes the ventilator to close. Once the rain stops and water evaporates from the rain detecting device, the circuit is broken and the electric motor 26 will cause the stay 22 to extend, opening the ventilator.
The rain detection means can be used to override any of the open positions and alternatively, it can be connected solely to the automatic adjustment of temperature within the enclosed area to be ventilated.
It is preferred when mounting the rain detection means that it should be mounted such that its surface having the interdigited portion 38 and 40 positioned at an angle of about 300 to the horizontal to allow water to run from the surface. Although 300 to the horizontal to allow water to run from the surface. Although 300 to the horizontal has been stated, it should be understood that the rain detection means may have an angle which varies from 00 to about 450 to the horizontal. The angle allows for natural washing and running down of water and dirt to increase the sensitivity of the rain detection means.
