- a typical fire suppressing system incorporates a sprinkler, or an array of sprinklers, that are positioned in the ceiling or above a cooking surface, for example in a range hood.
- a fire sensitive device is positioned somewhere in the room to detect the presence of a fire. When a fire is detected, the sprinkler system is enabled to attempt to suppress the fire.
- Such systems require complex installation, due to the geographically separate components of the system and the need to connect to a supply of water or other fire suppressant.
- US2003/010509 and JP 2004173993 both disclose a fire suppression apparatus arranged for connection to a kitchen water supply. It is an object of the present invention to provide a fire suppressor that draws from an existing water supply, or at least provides the public with a useful choice.
- a fire suppression apparatus adapted for installation on a kitchen bench and for connection to a water supply for a faucet, the apparatus comprising: a main body; a spout extending from the main body; a first valve operable into an open position by a person to release water through the spout; one or more spray nozzles connected to the main body; a second valve operable into an open position to fluidly couple the one or more spray nozzles to a water supply for a faucet; characterised by: a non-contact fire sensor positioned to detect a ceiling temperature a controller connected to the fire sensor adapted to operate the second valve into a closed position when the fire sensor senses a temperature below a second threshold, and wherein upon sensing a fire, the fire sensor outputs a signal to trigger the controller to operate the second valve into the open position; and a power source for the sensor, controller and/or second valve.
- the first valve is operable into the open position by a person to release water through the spout.
- the at least one second valve is normally in a closed position that fluidly decouples the one or more spray nozzles from a water supply for a faucet.
- the fire sensor is an infrared temperature sensor.

- the invention is said to comprise in the power source being one or more of:
- This specification describes a fire suppressing apparatus for installation in an area nearby a potential fire hazard or hazards.
- the area may be a kitchen.
- a kitchen often hosts numerous cooking appliances that may cause a fire.
- Such cooking appliances comprise ovens, stove tops, toasters.
- fire extinguisher A fire suppressor is more commonly termed a "fire extinguisher”. These terms can generally be used interchangeably. It will be appreciated that due to various factors, fire extinguisher may not always completely extinguish a fire. However, at least partially extinguishing or suppressing a fire does provide benefits in controlling a fire.
- the term "faucet” in this specification is intended to refer to any type of tap or mixer used to control a water supply.
- the faucet may be a single water outlet, or mix several water supplies together, such as hot and cold water supplies.
- a fire suppressing apparatus 3 is placed proximate an existing water supply 4, 5.
- the water supply may exist to supply, for example, existing faucets and water consuming appliances.
- the apparatus 3 could be installed on or near a kitchen sink 31.
- the fire suppressing apparatus of the invention comprises a plurality of spray nozzles.
- Each spray nozzle is preferably aimed at a potential fire hazard.
- Figure 1 illustrates a pair of spray nozzles wherein one spray nozzle is aimed toward an oven or stove top 1, and another spray nozzle is aimed toward a bench top 2.
- the desired spray pattern of each spray nozzle can be customised for the particular area when the fire suppressing apparatus is installed.
- the fire suppressing apparatus 3 could comprise a spout and mixer device that connects to an existing hot and/or cold water supply thus replacing an existing faucet.
- the fire suppression device may connect to the mains or other water supply by any common plumbing connection, for example, by welding the pipes or a threaded interlocking connection.
- the fire suppressing apparatus is a unit without a spout and mixer placed in close proximity to an existing faucet, or at least in close proximity to an existing water supply.
- FIGs 2 and 3 show a first embodiment of the invention whereby the fire suppression apparatus is formed from a number of spray nozzles in a device which also has a spout and a manually operated water control device.
- the fire suppression device resembles a faucet of a type commonly found in a kitchen. This could be the kind of faucet that is commonly installed on a kitchen sink or bench surfaces 31. Therefore, the fire suppression apparatus can function as a faucet as well as a fire suppressor.
- Figure 3 shows a perspective view of the first embodiment illustrating in more detail internal components which form the fire suppression apparatus 19.
- the first embodiment of the invention has a spout and a mixer whereby the fire suppression apparatus is formed from a number of spray nozzles replacing an existing faucet.
- the fire suppression apparatus 19 comprises a main body 51 that is adapted to install on a kitchen sink or bench 31.
- a spout 30 extends from the main body 51 and a mixer handle 24 is connected to the main body 51.
- the mixer handle 24 can be swivelled and lifted by user to control the mixture and flow rate of hot and cold water through the spout 30.
- Two spray nozzles 26 are located above the handle. Each spray nozzle can be aimed in a desired direction, and with desired spray pattern and volume characteristics.
- a mixing unit is disposed in the main body 51.
- the mixing unit 20 is preferably supplied by mains pressure or any other supply normally used to supply a faucet.
- the mixing unit 20 is connected to a household hot and cold water supply 4, 5 through fluid channels 22, 23.
- the handle 24 is used to provide a user with control over the hot/cold mixture via internal linkage 25. Internal linkage 25 actuates the mixing valve mechanism within the mixing unit 20.
- the handle also allows the user to control fluid flow rate to the spout 30.
- Fluid channel 44 connects the mixing unit to the outlet of the spout.
- the fire suppressing apparatus also comprises a fire sensor 28 that can sense smoke, heat and/or fire, or another indicator of fire, and a controller unit 21 for operating a valve 42 (shown in Figure 4 ). These allow for detection of a fire and control of water supply to the spray nozzles in response.
- FIG 4 illustrates an example of the internal components of the mixing unit 20.
- the hot and cold water channels 22, 23 are fluidly connected to the mixing unit 20.
- the cold water channel 22 is split into two fluid channels 57, 58 by a tee 40.
- the tee 40 is defined by any type of fluid diverging connection as known in the art.
- Fluid channel 58 fluidly connects the mains pressure household cold water channel 22 to a valve 42.
- the valve 42 may be any type of fluid barrier controllable either directly or indirectly by an electrical signal.
- the valve 42 is operated by an electrical solenoid between an open and closed position. Pressurised water from supply channel 22 is fluidly connected to supply channel 45 when the valve 42 is in the open position. Pressurised water from supply channel 22 is fluidly disconnected from channel 45 when the valve 42 is in the closed position.
- wire 46 An electrical signal to operate the valve 42 is supplied through wire 46 from the controller 21.
- the simplest form of wire 46 is a single wire supplying a positive voltage, wherein an electrical ground connection is supplied through the body of the internal components.
- wire 46 may comprise two wires that are isolated from other components in the fire suppressing apparatus.
- Fluid channel 57 remains fluidly connected to a mixing unit 41 independent of operation of the valve 42.
- fluid channel 58 remains fluidly connected to valve 42 independent of the operating of the mixing unit 41.
- valve 42 may be plumbed directly to supply channel 22 and provide a first and second output.
- the first output is plumbed to the mixing unit 41, and a second output is plumbed to the spray nozzles 26.
- Valve 42 would divert the water supply to the first output during normal faucet operation, and to the second output if a fire is detected.
- the fire sensor 28 is located on an exterior surface of the fire sensing apparatus 19.
- the fire sensor unit is a remote or non-contact fire or heat sensor or similar.
- the fire sensor 28 is coupled to the controller 21 by a wire 48.
- An example of a remote heat sensor is an infrared temperature fire sensor 28, or infrared thermometer.
- An infrared thermometer has a voltage output that corresponds to the temperature in an aimed direction. Ideally the aimed direction is at the ceiling of a room directly, or at least approximately, above a potential fire hazard.
- the aimed direction is at any ceiling space above the fire suppression apparatus where heat from a fire may rise to.
- the fire sensor could be located anywhere suitable that allows it to measure the heat of objects about the fire suppression apparatus, such as the ceiling.
- the location may be at, or near the top of the fire suppression apparatus.
- the protective cover 29 may be advantageous to provide a protective cover 29 above the sensor.
- the protective cover 29 transmits substantially all infrared radiation that is incident to it.
- Germanium or glass has proved an effective infrared transmitting material to construct a protective cover.
- Controller unit 21 is supplied with electrical power via wire 47.
- the electrical power is preferably of low voltage and low current for safety in the presence of water.
- the electrical power is of sufficient voltage and current that the fire sensor 28, controller 21 and solenoid valve 42 may operate simultaneously without failure.
- the controller unit 21 monitors the output of the fire sensor 28 via wire 48.
- the controller unit either alone or together with the fire sensor forms a fire detection unit.
- the output of the fire sensor 28 is representative of the ceiling temperature.
- the ceiling temperature will rise when there is a fire in the room before any other part of the room.
- the controller unit 21 incorporates an upper predetermined temperature threshold that corresponds to the occurrence of a fire.
- the controller unit signals valve 42 to open via wire 46 when a temperature threshold is exceeded.
- the opening of the valve 42 fluidly connects the pressurised mains water source 22 to the plurality of spray nozzles 26 via the fluid channel 45.
- the spray nozzles therefore spray water in a direction determined upon installation of the fire suppressing apparatus.
- the controller unit 21 incorporates a lower predetermined temperature threshold that corresponds to when a fire has been suppressed. Controller unit 21 closes valve 42 when the fire sensor 28 determines the ceiling temperature has dropped below the lower predetermined threshold. Accordingly, spraying will cease when the pressurised water supply is disconnected from the spray nozzles.
- the upper ceiling temperature threshold required for the controller unit 21 to open the valve 42 has been found to work well when set to between 40°-70° degrees Celsius.
- the lower temperature threshold required for the controller unit 21 to close the valve has been found to work well when set to between 40°-70° degrees Celsius.
- the upper and lower predetermined temperature thresholds may be equal, or different.
- the temperature thresholds may further be customised to a particular room requirement. For example, a large room may require a lower upper ceiling temperature threshold than a small room.

Figure 17 is an illustration of the fire suppression apparatus, which is not part of the present invention incorporating a hydroelectric generator. - This specification describes a fire suppressing apparatus for installation in an area nearby a potential fire hazard or hazards. For example, the area may be a kitchen. A kitchen often hosts numerous cooking appliances that may cause a fire. Such cooking appliances comprise ovens, stove tops, toasters.
- A fire suppressor is more commonly termed a "fire extinguisher". These terms can generally be used interchangeably. It will be appreciated that due to various factors, fire extinguisher may not always completely extinguish a fire. However, at least partially extinguishing or suppressing a fire does provide benefits in controlling a fire.
- The term "faucet" in this specification is intended to refer to any type of tap or mixer used to control a water supply. The faucet may be a single water outlet, or mix several water supplies together, such as hot and cold water supplies.
- Referring to
Figure 1 , afire suppressing apparatus 3 according to the invention is placed proximate an existingwater supply apparatus 3 could be installed on or near akitchen sink 31. - The fire suppressing apparatus of the invention comprises a plurality of spray nozzles. Each spray nozzle is preferably aimed at a potential fire hazard.
Figure 1 illustrates a pair of spray nozzles wherein one spray nozzle is aimed toward an oven orstove top 1, and another spray nozzle is aimed toward abench top 2. The desired spray pattern of each spray nozzle can be customised for the particular area when the fire suppressing apparatus is installed. - It may also be advantageous to include a general sprayer designed to spray a mist of water across a local area to effectively douse all local surfaces in case of the fire spreading.
- The
fire suppressing apparatus 3 could comprise a spout and mixer device that connects to an existing hot and/or cold water supply thus replacing an existing faucet. The fire suppression device may connect to the mains or other water supply by any common plumbing connection, for example, by welding the pipes or a threaded interlocking connection. Alternatively, but not part of the present invention, the fire suppressing apparatus is a unit without a spout and mixer placed in close proximity to an existing faucet, or at least in close proximity to an existing water supply. -
Figures 2 and3 show a first embodiment of the invention whereby the fire suppression apparatus is formed from a number of spray nozzles in a device which also has a spout and a manually operated water control device. In this case the fire suppression device resembles a faucet of a type commonly found in a kitchen. This could be the kind of faucet that is commonly installed on a kitchen sink or bench surfaces 31. Therefore, the fire suppression apparatus can function as a faucet as well as a fire suppressor.Figure 3 shows a perspective view of the first embodiment illustrating in more detail internal components which form thefire suppression apparatus 19. - Referring to
figures 2 and3 the first embodiment of the invention has a spout and a mixer whereby the fire suppression apparatus is formed from a number of spray nozzles replacing an existing faucet. Thefire suppression apparatus 19 comprises amain body 51 that is adapted to install on a kitchen sink orbench 31. Aspout 30 extends from themain body 51 and amixer handle 24 is connected to themain body 51. The mixer handle 24 can be swivelled and lifted by user to control the mixture and flow rate of hot and cold water through thespout 30. Twospray nozzles 26 are located above the handle. Each spray nozzle can be aimed in a desired direction, and with desired spray pattern and volume characteristics. - A mixing unit is disposed in the
main body 51. The mixingunit 20 is preferably supplied by mains pressure or any other supply normally used to supply a faucet. For example, the mixingunit 20 is connected to a household hot andcold water supply fluid channels handle 24 is used to provide a user with control over the hot/cold mixture viainternal linkage 25.Internal linkage 25 actuates the mixing valve mechanism within the mixingunit 20. The handle also allows the user to control fluid flow rate to thespout 30.Fluid channel 44 connects the mixing unit to the outlet of the spout. - The fire suppressing apparatus also comprises a
fire sensor 28 that can sense smoke, heat and/or fire, or another indicator of fire, and acontroller unit 21 for operating a valve 42 (shown inFigure 4 ). These allow for detection of a fire and control of water supply to the spray nozzles in response. -
Figure 4 illustrates an example of the internal components of the mixingunit 20. The hot andcold water channels unit 20. Thecold water channel 22 is split into twofluid channels tee 40. Thetee 40 is defined by any type of fluid diverging connection as known in the art. -
Fluid channel 58 fluidly connects the mains pressure householdcold water channel 22 to avalve 42. Thevalve 42 may be any type of fluid barrier controllable either directly or indirectly by an electrical signal. Preferably thevalve 42 is operated by an electrical solenoid between an open and closed position. Pressurised water fromsupply channel 22 is fluidly connected to supplychannel 45 when thevalve 42 is in the open position. Pressurised water fromsupply channel 22 is fluidly disconnected fromchannel 45 when thevalve 42 is in the closed position. - An electrical signal to operate the
valve 42 is supplied throughwire 46 from thecontroller 21. The simplest form ofwire 46 is a single wire supplying a positive voltage, wherein an electrical ground connection is supplied through the body of the internal components. Alternativelywire 46 may comprise two wires that are isolated from other components in the fire suppressing apparatus. -
Fluid channel 57 remains fluidly connected to amixing unit 41 independent of operation of thevalve 42. Similarly,fluid channel 58 remains fluidly connected tovalve 42 independent of the operating of the mixingunit 41. - It can be appreciated that for practicality one, or some, or all of the
tee 40,fluid channel 58,valve 42 andfluid channel 45 components can be located outside the mixingunit 20 without departing from their intended purpose. - As a further alternative,
valve 42 may be plumbed directly to supplychannel 22 and provide a first and second output. The first output is plumbed to the mixingunit 41, and a second output is plumbed to thespray nozzles 26. -
Valve 42 would divert the water supply to the first output during normal faucet operation, and to the second output if a fire is detected. - Loss in water pressure to the spray nozzles is avoided by the mixer unit being isolated from the spray nozzles when a fire is detected and the faucet is on. This means that the fire suppressing apparatus works when the mixer/spout is operating.
- Referring again to
figure 3 , thefire sensor 28 is located on an exterior surface of thefire sensing apparatus 19. Preferably the fire sensor unit is a remote or non-contact fire or heat sensor or similar. Thefire sensor 28 is coupled to thecontroller 21 by awire 48. An example of a remote heat sensor is an infraredtemperature fire sensor 28, or infrared thermometer. An infrared thermometer has a voltage output that corresponds to the temperature in an aimed direction. Ideally the aimed direction is at the ceiling of a room directly, or at least approximately, above a potential fire hazard. - Alternatively, the aimed direction is at any ceiling space above the fire suppression apparatus where heat from a fire may rise to.
- Alternatively the fire sensor could be located anywhere suitable that allows it to measure the heat of objects about the fire suppression apparatus, such as the ceiling. The location may be at, or near the top of the fire suppression apparatus.
- It may be advantageous to provide a
protective cover 29 above the sensor. Preferably theprotective cover 29 transmits substantially all infrared radiation that is incident to it. Germanium or glass has proved an effective infrared transmitting material to construct a protective cover. -
Controller unit 21 is supplied with electrical power viawire 47. The electrical power is preferably of low voltage and low current for safety in the presence of water. Preferably the electrical power is of sufficient voltage and current that thefire sensor 28,controller 21 andsolenoid valve 42 may operate simultaneously without failure. - The
controller unit 21 monitors the output of thefire sensor 28 viawire 48. The controller unit either alone or together with the fire sensor forms a fire detection unit. Preferably the output of thefire sensor 28 is representative of the ceiling temperature. The ceiling temperature will rise when there is a fire in the room before any other part of the room. Accordingly thecontroller unit 21 incorporates an upper predetermined temperature threshold that corresponds to the occurrence of a fire. The controller unit signalsvalve 42 to open viawire 46 when a temperature threshold is exceeded. - The opening of the
valve 42 fluidly connects the pressurisedmains water source 22 to the plurality ofspray nozzles 26 via thefluid channel 45. The spray nozzles therefore spray water in a direction determined upon installation of the fire suppressing apparatus. - Preferably, the
controller unit 21 incorporates a lower predetermined temperature threshold that corresponds to when a fire has been suppressed.Controller unit 21 closesvalve 42 when thefire sensor 28 determines the ceiling temperature has dropped below the lower predetermined threshold. Accordingly, spraying will cease when the pressurised water supply is disconnected from the spray nozzles. - The upper ceiling temperature threshold required for the
controller unit 21 to open thevalve 42 has been found to work well when set to between 40°-70° degrees Celsius. The lower temperature threshold required for thecontroller unit 21 to close the valve has been found to work well when set to between 40°-70° degrees Celsius. However, the upper and lower predetermined temperature thresholds may be equal, or different. The temperature thresholds may further be customised to a particular room requirement. For example, a large room may require a lower upper ceiling temperature threshold than a small room. -
Figure 5 provides analternative exterior 60 to thefire suppression apparatus 19 of the first embodiment. This functions in the same manner. -
Figure 6 provides an exploded view of the components of thefire suppression apparatus 19 inFigure 5 that layer to construct thefire suppression apparatus 19 of the preferred embodiment. Thefire suppression apparatus 19 has one ormore base components 51 that are designed to mount to a surface. For example, the surface may be a kitchen bench. Thebase components 51 may also support thespout 30. Other components include ahandle layer 52 that connects to thehandle 24, one or more spraynozzle housing layers 53, and acap 50. - Each of the spray
nozzle housing layers 53 contains aninternal fluid channel 27.Fluid channel 27 is designed to connect tofluid supply channel 45. Layering multiple spray nozzle housing layers fluidly connects the internal fluid channels between layers. -
Cap 50 is designed to house or support thefire sensing device 28.Cap 50 is also designed to terminatefluid channel 27 when located above the uppermost spraynozzle housing layer 53. - Preferably each of the
modular layers nozzle housing layers 53 may be freely rotated during installation to directspray nozzles 26 in a desired direction, such as shown infigure 1 . - Alternatively each of the spray nozzles may be plumbed directly to
fluid supply channel 45, where thechannel 45 is split as many ways as there are spray nozzles. The channel could be split by tee connections or similar. - Alternatively, each spray nozzle may be fluidly connected to the pressurised mains
water supply source 22 via an independent valve. When the control unit senses a fire it selectively opens one or more of the valves. - Alternatively, each of the spray nozzles may be connected as a group that consists of one or more spray nozzles. Each group is connected to the pressurised mains
water supply source 22 via an independent valve. When the control unit senses a fire it selectively opens one or more of the valves to fluidly connect one or more groups of spray nozzles. - Preferably the spray
nozzle housing layers 53 are layered above thehandle layer 52 and the one or more base layers 51. The protrudinghandle 24 and protrudingspout 30 may intercept the spray pattern from thespray nozzles 26. - However, the spray nozzle housing layers may be placed below other layers if adequately spaced apart, or at least designed such the spray pattern is not intercepted. An interception of the spray pattern may cause detrimental performance to the fire suppressing intention of the apparatus.
-
Figures 7 and8 illustratealternative exteriors nozzle housing layers 53 are located beneath thehandle layer 52. It may be advantageous to locate the spray nozzles above the handle in certain situations where thehandle 24 is large enough to intercept the spray pattern from the spray nozzle. - In another alternative, the fire suppression apparatus comprises a spout, without user operable valves and handles. In this case, the handles and valves (such as hot and cold water tap handles) are amounted proximate to the spout but separate.
-
Figures 9 and10 illustrate a view of embodiment of the fire suppression apparatus, which is not part of the invention.Figure 9 shows the apparatus in expanded form. The embodiment is formed by layering abase unit 51, one or more spraynozzle housing layers 53 and a terminatingcap 50. The fire suppression apparatus of the second embodiment is intended to be installed on a surface proximate an existing faucet, or at least proximate an existing water supply. In this way the apparatus can be installed in an existing area containing potential fire hazards. - An advantage the apparatus of the second embodiment provides is the versatility to be positioned with clear line of sight to a potential fire hazard. The apparatus may also be installed by, for example, a home owner that does not want to change their existing faucet.
- The spray nozzles 26 can be rotated such that they can be aimed in the direction of a potential fire hazard when die apparatus is installed. The apparatus may be installed on a bench top or kitchen sink top nearby and existing faucet or somewhere convenient in the kitchen.
- The spray pattern of each of the spray nozzles can be customised to best suit the potential fire hazards in the area.
- Each of the spray
nozzle housing layers 53 contains aninternal fluid channel 27.Fluid channel 27 is designed to connect tofluid supply channel 45. Layering multiple spray nozzle housing layers fluidly connects the internal fluid channels between layers. -
Figure 11 shows an internal view of the embodiment, which is not part of the invention, where thecontroller 21 andvalve 42 are housed internal to the fire suppression apparatus. The apparatus has afluid channel 22 connected to thevalve 42.Valve 42 is electrically opened and closed by acontroller 21 viawire 46. Afire sensor 28 is electrically connected to thecontroller 46 viawire 48.Valve 42 is opened bycontroller 21 when a fire is sensed.Fluid channel 22 is fluidly connected to one ormore spray nozzles 26 viainternal fluid channel 27 when thevalve 42 is opened. -
Fluid channel 22 may be a length of pipe having an adaptation for connecting to an existing mains water supply. The adaptation may comprise a tee connection that separates the water supply into at least two paths as shown inFigure 4 . The fluid channel may also be connected to the base of the unit via aconnection 76. Theconnection 76 may be a standard threaded connection as is commonly used in the plumbing industry, or it may be attached by other similar methods, such as welding or an interference fit. -
Figure 12 is a diagram of the fire suppression apparatus according to the embodiment, which is not part of the invention, having thecontroller 21 andvalve 42 housed externally. Thecontroller 21 andvalve 42 are contained within anouter housing 70. Thehousing 70 can be attached to a convenient wall or inside surface of a cupboard or bench. Thehousing 70 protects the valve and controller structure from external interference. In addition, thehousing 70 may physically support the components contained internally. - The
controller 21 is supplied with power from an external wall adapter unit ormains connection 71 viawire 47. Thecontroller 21 outputs electrical control signals tonearby valve 42 viawire 46, in response to electrical signals from the remote fire sensor viawire 48. - A cold
water supply channel 22 is supplied to thehousing 70. Ahot water supply 23 is not connected to the apparatus. Thewater supply 22 is fluidly connected to thevalve 42 inside thehousing 70.Water channel 72 exits thehousing 70 and may connect to existing nearby faucets or other water consuming devices. Thewater supply channel 22 is fluidly connected towater channel 72 during normal operation. When a fire is detected, thewater channel 22 is fluidly connected to the spray nozzles and fluidly disconnected fromchannel 72. - A clamping
surface 73 is attached to the lower end of the fire suppression apparatus via a threadedmember 74. The threadedmember 74 can be spun to raise and lower the height of the clampingsurface 73 relative to the base of theapparatus 75. The apparatus can therefore be secures to a bench top via the clamping surface. For example, theapparatus 90 can be located above an aperture in the bench that allows thewater channel 45 andelectrical connection 45 to pass through. The threadedmember 74 is rotated until the clampingsurface 73 has been pressed into the lower surface of the bench top thus securing the apparatus. -
Figures 13 ,14 and15 show a cross sectional view of a second embodiment of the fire suppression apparatus of the present invention from various angles. - Referring generally to these three figures, the third embodiment consists of three main sections. These are the
handle section 80 located at the top of the unit, thefaucet section 81 located in the centre of the unit and thefire suppression section 82 located at the base of the unit. - The
handle section 80 has alinkage 83 that connects thehandle 84 to amixer unit 85. Themixer unit 85 is a mixer cartridge of the type commonly used in the faucet industry. The mixer cartridge is typically a valve that receives a hot and cold water supply viainput channels ceramic plate 88 swivels to control the mix ratio of the hot and cold water supplies before channelling the mix to aspout 89. Those skilled in the art will know how this mixer cartridge operates. - The hot and cold water supply is fed via
water channels water supply channel 91 has an aperture, orapertures 93 for water to flow through into avalve 94. Preferably thevalve 94 is an electromagnetic two way valve. Water remains in alower chamber 95 when thevalve 94 is closed or in a de-energised state. When thevalve 94 is open, or in an energised state, water is allowed to flow through theapertures 93, thelower chamber 95 and into anupper chamber 96. - Preferably
upper chamber 96 fluidly extends around the periphery of the lower section of theunit 82 to form anannular fluid channel 102. Theupper chamber 96 is in fluid communication with a set ofspray nozzles 97 via theannular fluid channel 102. Whenvalve 94 is open, water from thewater supply channel 91 is fluidly connected to spraynozzles 97. The fluid connection of the pressurised water supply to thespray nozzles 97 provides a stream of water that may be used to suppress a fire. - Located at the base of the fire suppression apparatus is a
fire sensor 98. Thefire sensor 98 can be aimed at the ceiling of a room above a potential fire hazard. The fire sensor is electrically connected to an embeddedcontroller unit 99. The controller unit receives power via anelectrical connection 100 and an input from thefire sensor 98. Thecontroller 99 outputs a control signal tovalve 94 when thefire sensor 98 detects the occurrence of a fire. Thevalve 94 subsequently opens to allow pressurised water to flow fromwater channel 91 through theapertures 93, through thelower chamber 95 intoupper chamber 96 and therefore to thespray nozzles 97 viaannular channel 102. - When the
fire sensor 98 no longer detects the occurrence of a fire, or a predefined amount of time has elapsed, thecontroller 99 sends a control signal to closevalve 94. The control signal to closevalve 94 includes de-energising the electromagnetic coils in thevalve 94 to allow it to close. - Another embodiment of the apparatus, which is not part of the invention, is shown in
Figure 16 . This functions in the same manner as the embodiment as shown and described in relation tofigures 13 to 15 . However, this embodiment does not function as a faucet. -
Figure 17 shows one embodiment offire suppression apparatus 105, which is not part of the invention, connected to ahydroelectric generator 106. Thegenerator 106 is located in a water supply channel that supplies thefire suppressing apparatus 105 and anearby faucet 113. The generator has a propeller orturbine 112 that is spun by water flow to generate electricity. - The
generator 106 could be located in thewater channel 111 that supplies the nearby faucet or the mainwater supply channel 108. Alternatively thegenerator 106 could be located at the intersection of the mainwater supply channel 108, thesupply channel 108 to thefaucet 113 and thesupply channel 109 to thefire suppression device 105. - Electrical power generated by the spinning
propeller 112 is connected bywire 110 to thefire suppression device 105. Preferably the fire suppression device incorporates arechargeable battery 107 connected to the supply of power from the generator. Therechargeable battery 107 is used to supply power to the other electrical components housed in the fire suppression device. - A solar panel may be incorporated into the fire suppression device instead of the hydroelectric generator. Alternatively, the solar panel could work in parallel to the hydroelectric generator. Preferably the solar panel would be positioned in a sunlit location. The solar panel is connected to the rechargeable battery. The battery supplies electrical charge to the electrical components in the fire suppression device. Additionally, the solar panel recharges the battery. The solar panel may also be used to directly power one or more of the electrical components in the fire suppression device when output power is sufficient to do so.
-
Figure 17 shows the fire suppression device as a stand alone unit. According to the invention thegenerator 106, battery and/or solar panel could be incorporated into a fire suppression device that is part of a faucet, such as described earlier. Further, a standard battery could be used in place of the rechargeable battery. - The first, second and third embodiment can be supplied as a complete unit, or a kit of parts for assembly into a complete unit.
