Description
SPECIFICATION
Solar ventilator and solar powered air modifier
The present invention relates to a solar ventilator and additionally relates to a solar
powered air modifier.
In certain forms of accommodation which may
be left unattended for a period of time it is desirable that the air content of the
accommodation should be regularly changed.
Such a regular change of air helps to mitigate
problems such as the formation of mould on the interior surfaces of the accommodation or on articles stored within the accommodation. Such
problems are often associated with caravans and boats. A similar regular change of air is also desirable for greenhouses, but in this application the ventilation is required so as to prevent the greenhouse from overheating during sunny periods.
A device is known which attempts to provide the desired air change and which is specifically adapted for use in greenhouses. This device consists of an arrangement of telescopic poles which have a high coefficient of linear thermal expansion and which act between a solid frame and a ventilation flap of the greenhouse. As the temperature within the greenhouse increases the telescopic poles expand and the flap is opened.
However, this known device is prone to malfunction in that the telescopic poles can easily become seized either with the ventilator flap open or closed. The effect of such malfunction upon the contents of the greenhouse can of course be disastrous.
The present invention seeks to provide a form of ventilation which is suitable for the above discussed applications and which is reliable in operation.
According to a first aspect of the present invention there is provided a ventilator comprising a motor, a fan and a solar cell, the solar cell being arranged to power the motor which in turn drives the fan when sufficient radiation impinges upon the solar cell.
This aspect of the present invention is simple in construction and reliable in operation and is found to be particularly suited to the described applications for a number of reasons.
According to a second aspect of the present invention there is provided a solar powered air modifier comprising a motor, a fan, a solar cell and means for housing a product to be dispersed by the modifier, the solar cell being arranged to power the motor so as to drive the fan and disperse the product when sufficient radiation impinges upon the solar cell.
Conventional air fresheners rely upon the slow evaporation of a substance or upon the use of an aerosol propel lent. With the former, it is difficult to obtain the desired degree of fragrance and this can also be a problem with the latter as well. The use of an aerosol propellent is relatively expensive and can also introduce undesirable substances into the air in addition to the desired fragrance substance. Aerosols are dangerous if punctured or heated.
This second aspect of the present invention avoids or mitigates these problems associated with conventional air fresheners. The solar powered air modifier is easily controlled by partially or completely covering the solar cell and it is therefore automatically "switched off" when stored in a dark cupboard.
According to a further aspect of the present invention there is provided a solar powered device consisting of at least a motor, a fan, and a solar power unit. The solar power unit being arranged to power the motor for driving the fan, and further comprising an electric energy storage device which is connected to receive energy from the solar power unit and which is connectable to drive the fan.
The solar powered device of this third aspect of the invention may additionally include means for housing a product which is to be dispersed by motion of the fan, thereby constituting a solar powered air modifier.
Preferably, the solar powered unit is of sufficient capacity and is arranged to drive the fan and charge the storage device simultaneously.
Advantageously, the solar powered device of this aspect of the invention includes a control circuit connected between the solar power unit and the storage device so as to regulate charging of the storage device and prevent overcharging thereof. The solar powered device also beneficially includes a control unit for sensing the power supplied from the solar power unit directly to the fan and for effecting power supply from the storage device when the power supplied to the fan directly from the solar power unit falls below a pre-set threshold.
Embodiments of the present invention will now be described by way of example only and with reference to the accompanying drawing which illustrates a partial vertical section through a solar ventilator.
The illustrated solar ventilator comprises a housing 10 which accommodates a solar cell 12, a motor 14 and a fan 16. The housing 10 is shown as being of unitary construction although the housing may in practice be assembled from several components. The housing 10 has a circular flange 1 8 which is used for fixing the ventilator in position in combination with an additional fixing element. Two additional fixings 20 and 22 are illustrated and these can be used as alternative arrangements.
The flange of the housing 1 8 is located on one side of a window, wall or the like and the relevant fixing member located on the opposite surface of the window, wall or the like. Where the fixing element 20 is used, the fixing element and the flange 18 may be secured together by means of bolts or self tapping screws etc. The fixing element 22 can be of a simple annular shape and can be secured to the ventilator 10 by means of an interference type fit so that the use of self tapping screws, bolts etc is avoided in fixing the ventilator into position.
The housing 10 carries a conventional solar cell 1 2 in a recess on its external surface. The solar cell 12 may be bonded to the housing 10 for additional security. The solar cell 12 is coupled to a motor 14 which is accommodated within the housing 10 and which is held in position by bracing elements 24. The motor 14 includes a spindle 26 to which the fan 1 6 is attached.
When solar radiation impinges upon the solar cell 1 2 electric power is generated which is transferred to the motor 14 and when the incident solar radiation is sufficiently high the motor 14 drives the fan 16 by way of spindle 26. Air flows through the apertures 28 provided in the housing
10 and additional air flow passages are provided as and where necessary.
It will be readily appreciated that the housing
10 and fixing elements 20 and 22 can be readily formed in plastics materials using known techniques.
By reversing the electrical connections between the solar cell and the motor, the direction of flow of air directly driven by the fan can be reversed.
The illustrated solar ventilator is particularly useful when used in certain forms of accommodation which may be left unattended for a period of time. In such accommodation it is desirable that the air content of the accommodation should be regularly changed.
Such a regular change of air helps to mitigate problems such as the formation of mould on the interior surfaces of the accommodation or on articles stored within the accommodation. Such problems are often associated with caravans and boats. A similar regular change of air is also desirable for greenhouses, but in this application the ventilation is required so as to prevent the greenhouse from overheating during sunny periods.
The solar ventilator is simple in construction and reliable in operation and is found to be particularly suited to the described applications for a number of reasons.
In particular, the solar ventilator tends to become inoperative whenever the weather produces rain since at such time the rain clouds tend to prevent sufficient radiation impinging upon the solar cell to drive the motor. Thus an ingress of heavily moist air through the ventilator tends to be prevented. It has been found that the annual total of hours of sunshine within countries such as the United Kingdom is remarkably stable.
Consequently, it is possible to predict the average rate of change of air content effect by the ventilator over a period of time of say a month or two. This enables the optimum size of ventilator to be selected for the particular application. In medium strength sunlight it has been found possible to effect a complete change of air in a room of approximately 30 cubic metres in a period of six hours using a conventional solar cell of 7.5 centimetre diameter and a similarly sized fan. Much superior rates of change of air are possible when the size of solar cell employed is increased.
The application of the solar ventilator of this invention to greenhouses is beneficial. Similar to the described known device the ventilator will moderate the internal temperature of the greenhouse during sunny periods. However, unlike the known device, the present ventilator is reliable in operation and is not prone to components becoming seized due to thermal expansion. The components of the present ventilator can be formed of materials having low coefficience of thermal expansion.
A second aspect of the present invention provides a solar powered air modifier. Such an air modifier is based upon the above described solar ventilator with the addition of means for housing a product to be dispersed by the modifier.
Rotation of the fan when sufficient radiation impinges upon the solar cell causes an air freshening product to be dispersed.
In one embodiment crystals of an air freshener product are contained in the housing which also accommodates the solar cell 12, motor 14 and fan 1 6. When sufficient radiation impinges upon the solar cell 12, the fan 16 blows air across the crystals and this results in a pleasant fragrance being emitted by the device.
Advantageously, the housing 10 can be provided with a stand and it is therefore readily located within a room adjacent a window through which the sun is shining. The air modifier can be operated by directing the light from a suitable lamp onto the solar cell 12.
The solar powered air modifier is particularly advantageous due to its simplicity, ease of manufacture, reliability, ease of use and the provision of a powered air modifier without the use of mains electricity, a batter power supply or an aerosol propellent.
The solar powered air modifier mitigates the problems of conventional air fresheners such as difficulty in controlling the rate of evaporation or the expense and dangers associated with using aerosol propellents.
The solar powered air modifier is easily controlled by partially or completely covering the solar cell 12 and is therefore automatically "switched off" when stored in a dark cupboard.
The means for housing the product to be dispersed can be a receptacle, the exact form of which will depend upon the product to be used.
For use with crystals a small cage may be employed whereas for use of a liquid a dish is preferable. If a solid product is used to provide the required air modifying substance, then the product can be held by a series of projections or grooves in the housing 10 of the modifier, adjacent the fan 1 6. In one embodiment a band of solid material impregnated with an air freshening substance can be positioned within the housing 10 against the internal wall thereof so as to surround the fan 16. In this example the housing 10 is provided with a removable portion which enables ready insertion and replacement of the air freshening band.
Although described above with reference to an air freshener, the solar powered air modifier can be used in many other applications. It is particularly suitable for dispersing an insecticide in a greenhouse especially for the treatment of insects which are most prevalent in sunny weather. Similarly, the air modifier is particularly advantageous in mitigating obnoxious smells of certain types which become apparent in sunny weather.
A further aspect of the present invention provides a solar powered device consisting of at least a motor, a fan and a solar power unit, the solar power unit being arranged to power the motor for driving the fan, and further comprising an electric energy storage device which is connected to receive energy from the solar power unit and which is connectable to drive the fan.
The solar powered device may additionally include means for housing a product which is to be dispersed by motion of the fan, thereby constituting a solar powered air modifier as described above.
Preferably, the solar power unit is of sufficient capacity and is arranged to drive the fan and charge the storage device simultaneously.
Advantageously, the solar powered device includes a control circuit connected between the solar power unit and the storage device so as to regulate charging of the storage device and prevent overcharging thereof. The solar powered device also beneficially includes a control unit for sensing the power supplied from the solar power unit directly to the fan and for effecting power supply from the storage device when the power supplied to the fan directly from the solar power unit falls below a pre-set threshold.
The solar powered device of this aspect of the invention has the additional advantages provided by operation during weak sunlight and at night.
This is effected by the provision of a rechargeable battery which is connected to the solar power unit which drives the fan of the ventilator. The solar power unit comprises a number of solar cells one group of which is directly connected to drive the fan whilst the remaining group of solar cells is connected to charge the battery.
The ventilator includes a control circuit for regulating charging of the battery and preventing overcharge thereof. Such control circuits are well known. The ventilator also incorporates a control circuit for sensing the power supplied by the respective group of solar cells to the fan. When said power supplied to the fan falls below a threshold value, the battery is connected to the fan. Consequently, the fan continues to operate despite the fact that insufficient radiation is impinging upon the solar power unit to directly drive the fan. The solar ventilator will therefore continue to operate during periods of weak sunlight, for example when clouds obscure the sun, and at night.
Additional control features may be incorporated in the solar ventilator in accordance with the desired application. For example, a time delay may be incorporated so that power is not supplied from the battery immediateiy upon power from the solar power unit falling below the threshold. This arrangement will avoid discharging the battery, for example, during temporary cloud cover. The control circuits may additionally or alternatively include timing elements so that the fan is only driven, for example, for a specified time in each hour during which the fan is not directly driven by the solar power unit.
With the addition of means for housing a product to be dispersed by the fan, the above arrangement provides a solar powered air modifier having the same advantages as those described above in relation to the solar ventilator with the additional electric storage facility. The applications of the solar powered air modifier can be greatly extended and enhanced by the inclusion of the rechargeable battery particularly when used in combination with the above described control circuits. The timing control circuits are particularly advantageous where the air modifier is in the form of an air freshener which is used in an environment with a constant background odour, for example, in certain parts of hospitals. The air modifier will also greatly benefit from the inclusion of the rechargeable battery and control circuits when used for dispensing agricultural products such as fertilisers or pest control products. in such applications a regular dosage of the product may be highly desirable but which may be impractical with conventional power units.
Modern rechargeable batteries such as nickelcadmium and lithium batteries enable the above described devices to require only the minimum of maintenance and will not significantly detract from the ease of manufacture and installation of the devices.
