Abstract
After a predetermined service or maintenance interval a timer activates a cut off to prevent the supply of fuel to an appliance which runs on combustible fuel. At the end of the service interval, or shortly before, a message is sent to a remote location by E-Mail or telephone text messaging. The invention also extends to safety apparatus for cutting off the fuel supply to an appliance or device, which runs on combustible fuel, in response to receipt of a signal from a remote hazard detector. The apparatus comprises a valve (10) mounted within a housing (12) which is disposed between the outlet of the fuel supply and the fuel inlet of the appliance or device. The apparatus further comprises a radio signal receiver unit (26) for receiving a signal from a remote hazard detector (not shown), such as a fire, smoke, gas or carbon monoxide detector. The valve (10) is usually in a position so as to permit fuel flow between the fuel supply and the appliance or device via the housing interior. However, if the receiver unit (26) receives a signal from the hazard detector indicating the presence of a potential hazard, the valve is deployed (by means of solenoid 24) so that a blocking plate (22) moves to a position in which it blocks the fuel flow path and effectively switches the appliance or device off. The invention also extends to apparatus for automatically cutting off the electricity supply to an electrical appliance or device in the event of a potential hazard being detected.
Description
-1 Safetv Apparatus This invention relates to safety apparatus and, more
particularly, to safety apparatus for interrupting or preventing the flow of fuel to a fuel-driven appliance or other device in the event of an emergency, such as a fire, a fuel leak or a build up of carbon monoxide or other harmful gas being detected within a predetermined area around the appliance or device.
Many appliances and devices run by combustion of carbon-based fuels. For example, gas burners and cookers are widely used, in both domestic and industrial premises, for heating, burning and cooking. Another example is an internal combustion engine used to drive most motor vehicles. Obviously, such appliances and devices pose a fire hazard in the event of a fuel leak and, in the event of a fire in the vicinity of such appliances and devices, there is a serious danger of an explosion due to the significant rise in temperature of the fuel caused by the fire.
Further, it is well known that respiring life forms are adversely affected by the inhalation carbon monoxide, smoke and other combustion products above a certain level. Indeed, inhalation of carbon monoxide, smoke and other combustion products can lead to death. As carbon monoxide is effectively colourless and odourless, an individual or animal that is inhaling carbon monoxide generally becomes overcome by the gas without realising why.
Carbonmonoxide often results from incomplete combustion of carbon-based fuels in a burner.
Faulty gas burners are often a source of carbon monoxide in buildings. Carbon monoxide is also formed in internal combustion engines, and can build up when the engine is run in a confined space. In addition, smoke frequently arises as a result of incomplete combustion in such devices and appliances.
Detectors exist and are widely used for detecting fire, smoke, carbon monoxide, gas leaks, and the like. Such detectors generally provide an audio and/or visual warning to a user of the presence of a hazard. Once the user is aware of the presence of a potential hazard, they can switch offany appliances and devices which run on combustible fuels, either to prevent further
-2 build up of smoke, carbon monoxide or other combustion products or to prevent an explosion caused by a fire.
However, it is obviously undesirable and, in many cases, dangerous or impossible for a user to enter the vicinity in which a hazard has been detected to switch the appliance or device off.
Further, the hazard may occur when there is nobody in the vicinity of the device or appliance (or the hazard detector), such that no action is taken to prevent or minimise the harmfi1 effects of the detected hazard.
Furthermore, although it is strongly advisable to have such devices or appliances serviced every, say, twelve months, many people to not adhere to such advice, with the potential effect that the appliance or device may be operated even though it may be faulty and potentially hazardous. I have now devised arrangements which overcome the problems outlined above. Thus, in accordance with a first aspect of the present invention, there is provided apparatus for interrupting or cutting off the fuel supply to an appliance or device which employs combustible fuel, the apparatus comprising cut-off means for preventing the flow of fuel to or within said appliance or device, receiving means for receiving a radio frequency signal from a remote location, and means for deploying said cut-offmeans to prevent said flow of fuel in response to the receipt of said signal.
The cut-off means preferably comprises a valve which may be mounted in a unit connected or connectable between the fuel supply and the appliance or device. The valve beneficially comprises a solenoid and a blocking device for blocking the flow of fuel from or through a pipe. In this case, the blocking means may be mounted within the flow path, with the solenoid also being mounted or disposed within the flow path, or externally thereof. The valve is preferably normally open, permitting the flow of fuel, and, in response to the receipt of a radio frequency signal from, for example, a smoke, fire or carbon monoxide detector, the solenoid is deployed to move the blocking means to a position in which it blocks the flow of fuel to the appliance or device.
-3 The receiver means may be battery powered and/or mains powered. In the case of a battery powered receiver means, the battery or batteries are preferably rechargeable. The apparatus may be usually run from the mains electricity supply, with a battery back-up being provided in case of failure of the mains supply.
Of course, it Is also often desirable to interrupt or switch offthe electricity supply to electrical appliances and devices in the event of a hazard, such as a fire, especially if that device or appliance is causing or has caused the hazard. Thus, in accordance with a second aspect ofthe present invention, there is provided apparatus for interrupting or cutting off the electricity supply to an electrical appliance or device, the apparatus comprising cut-off means for selectively preventing the passage of electricity to or within said appliance or device, receiving means for receiving a radio frequency signal from a remote location, and means for deploying said cut-off means to prevent said passage of electricity in response to the receipt of said signal. The cut-off means preferably comprises a trip switch which is beneficially deployed to break the connection between a mains power supply and the appliance or device in response to the receipt of a signal from, for example, a gas, fire or smoke detector.
In either case, the apparatus may be used to cut out the fuel or electricity supply to a plurality of devices or appliances connected thereto.
The present invention extends to an appliance or device including the apparatus of the first or second aspects of the present invention arranged to receive a radio frequency signal from remote hazard detector to cause the cut-off means in either case to be deployed.
In accordance with a third aspect of the present invention, there is provided apparatus for interrupting or cutting off the fuel supply to an appliance or device which employs combustible fuel, the apparatus comprising cut-off means for preventing the flow of fuel to or within said appliance or device and timing means for causing said cut-off means to be deployed when a predetermined period of time has elapsed.
The predetermined time may, for example, represent a service or maintenance period for the appliance or device.
The timing means and/or said cut-off means preferably includes a reset mechanism, and the reset mechanism is beneficially arranged such that it can only be operated by one or more authorised persons, such as a service engineer or the like, once the required maintenance or other action has been carried out in respect of the appliance or device.
The apparatus may include means for transmitting one or more messages to a remote location when the predetermined period of time has elapsed and/or shortly before the predetermined time has elapsed. Such means for transmitting messages may include or comprise a telephone dialling means, which is beneficially adapted to transmit an e-mail and/or telephone text message (SMS) to a remote location.
In accordance with a fourth aspect ofthe present invention, there is provided safety apparatus for use with an appliance or device which employs combustible Mel, the apparatus comprising cut-off means for preventing the flow of fuel to or within said appliance or device, means for deploying said cut-off means, and means for transmitting a message to a remote location in response to deployment of said cut-offmeans.
The apparatus may include detection means for detecting at least one combustion product in an area in which the appliance or device is located, and means for deploying the cut-offmeans in response to detection of said at least one combustion product. Alternatively, or in addition, the apparatus may include means for receiving a radio frequency signal from a remote location, and means for deploying said cut-off means in response to receipt of the signal.
The message transmitted to the remote location preferably includes an indication that a potentially hazardous situation exists in respect of said appliance or device, if that is indeed the case.
-5 The apparatus beneficially includes reset means for resetting the cutoff means and thereby permitting the flow of fuel to or within the appliance or device to resume. Again, such reset means is preferably operable only by one or more authorised persons.
In accordance with a fifth aspect of the present invention, there is provided safety apparatus for use with an appliance or device which employs combustible fuel, the apparatus comprising timing means for determining when a predetermined period of time has elapsed, and means for transmitting a message to a remote location when and/or shortly before said predetermined period of time has elapsed, indicating that action in respect of said appliance or device is required to be taken.
The means for transmitting a message may include or comprise a telephone dialler, which is., preferably adapted to transmit an e-mail or telephone text message (SMS) to a remote location indicating that action in respect of the appliance or device is required to be taken.
The safety apparatus of the fifth aspect of the invention may include cutoff means for preventing the flow of fuel to or within the appliance or device, and means for deploying the cut-off means when the abovementioned predetermined period of time has elapsed. The safety apparatus may again comprise reset means for resetting the timing means andlor the cute I offmeans, in which case the reset means is preferably operable only by one or more authorised persons. In all cases, the cut-off means beneficially comprises a valve disposed between the appliance or device and its fuel supply.
In all cases, means may be provided to play back a pre-recorded voice message, identifying for example a problem, potential problem, or an action required to be taken. This may be in addition to or instead of any other warning means.
The valve, when deployed, preferably blocks a fuel flow path between said fuel supply and the appliance or device. The valve may deployed by means of a solenoid, the solenoid being
provided with an electrical current or voltage in response to receipt of a signal from a remote location to move the valve to a position in which it prevents said flow of fuel to the appliance or device. The solenoid may be disposed within or externally of the fuel flow path.
The cut-off means may be disposed within a housing having an inlet connected or connectable to a fuel supply and an outlet connected or connectable to the appliance or device.
The safety apparatus may be operable by means of an electrical power supply, provided by a mains power supply and/or one or more (possibly rechargeable) batteries.
