Description
Socket Apparatus The present invention relates to socket apparatus and to a method of using such apparatus.
Many electrical devices and appliances need not be left powered on during an entire day.
Stand-by functions have become common place, but it is well known that leaving an electrical device or appliance in stand-by mode still draws a current, albeit being reduced. Even leaving an electrical device or appliance plugged in but with a main switch of the device or appliance switched off can still result in a small current being drawn. This is common in particular with computer printers. This all results in unnecessary power consumption, rising utility bills, and increased environmental damage.
The aforementioned electrical devices and appliances can be considered as non-essential', since their temporary deactivation or deenergisation has no knock-on effect or impact. Such devices and appliances can include a television, a radio, a kettle, a toaster, a gaming console, and a computer.
Other devices and appliances can be considered as essential', since their deactivation or deenergisation, even for a short period, can be detrimental. Such devices and appliances can include a fridge, a freezer, an alarm, a recording device, and a boiler.
The present invention seeks to provide a solution whereby non-essential' electrical devices can be easily and quickly fully deenergised and thus electrically isolated. When considering the solution, it is also important that utilisation of the available space is optimised. Controllers which plug in and effectively piggyback' off existing sockets are not suitable, since they project or protrude a significant distance, causing obstruction and hindrance.
According to a first aspect of the invention, there is provided socket apparatus for mounting to an electrical back box, the apparatus comprising a front support which is fastenable to an electrical back box, at least two electrical-plug sockets on the support element, and a master switch element which is spaced from the front support for remotely controlling at least one of the sockets.
Preferable and/or optional features of the first aspect of the invention are set forth in claims 2 to 23, inclusive.
According to a second aspect of the invention, there is provided a method of controlling a supply of electricity to non-essential electrical devices without disrupting a supply of electricity to essential electrical devices using socket apparatus in accordance with the first aspect of the invention, the method comprising the steps of: a) providing a plurality of first and second sockets which are fastenable to electrical back-boxes on an electrical circuit; b) plugging a non-essential electrical device into one of the first sockets; c) plugging an essential electrical device into one of the second sockets; and d) providing a master switch element for simultaneously remotely controlling only the first sockets.
Preferable and/or optional features of the second aspect of the invention are set forth in claims 26 to 30, inclusive.
The invention will now be more particularly described, by way of example only, with reference to the accompanying drawings, in which Figure 1 shows a diagrammatic view of a first embodiment of socket apparatus, in accordance with the first aspect of the invention and forming part of an electrical circuit; Figure 2 shows a front of a twin switched socket forming part of the socket apparatus; Figure 3 shows a rear of the twin switched socket; Figure 4 shows a diagrammatic view of a second embodiment of socket apparatus, in accordance with the first aspect of the invention and forming part of an electrical circuit; Figure 5 shows a rear of a twin switched socket forming part of the second embodiment of the socket apparatus; Figure 6 shows a front of a local switching device of the second embodiment of the twin switched socket; Figure 7 shows a diagrammatic view of a third embodiment of socket apparatus, in accordance with the first aspect of the invention and forming part of an electrical circuit; Figure 8 shows a rear of a twin switched socket forming part of the third embodiment of the socket apparatus; and Figure 9 shows a front of a local switching device of the third embodiment of the twin switched socket.
Referring firstly to Figures 1 to 3 of the drawings, there is shown a first embodiment of socket apparatus 10 which comprises a, typically wall-abuttable, front support housing 12, two switched electrical-plug sockets 14, 16 provided in and supported by the front support housing 12, and a master switch unit 18 which is remote from the front support housing 12. In this case, a plurality of the front support housings 12 with the two switched sockets 14, 16 are provided, but as few as one front support housing with two switched sockets may be utilised.
The front support housing 12 is formed in any standard manner and from any standard material, such as moulded plastics or metal. A removable front plate may be included in some cases for decorative purposes. The front support housing 12 is fastenable in normal fashion to a two gang electrical-socket back box, typically by using bolts. The back box may be surface mountable or recessed.
In this embodiment, each switched socket 14, 16 is electrically independent of the other, and thus includes at least its own dedicated Live and Neutral terminals 20, 22. Although not essential, each switched socket 14, 16 is spaced from the other and only mechanically interconnected by the front support housing 12.
The master switch unit 18 is preferably a double pole single throw switch 24 provided in or on a switch housing 26 mountable to a wall directly on a back box, which includes a wall-surface mounting box or a recessed box. The master switch unit 18 is also preferably mounted at a convenient location, such as at an entrance or exit, or at the bottom or top of a flight of stairs.
The apparatus 10 of the first embodiment also includes a contactor 28 which is electrically connected to a consumer unit 30 of the building. The master switch unit 18 is electrically connected to the contactor 28 by mains electricity wiring 32, typically embedded within walling. The contactor 28 also supplies electricity at mains voltage and current via two separate, again typically embedded, ring mains 34, 36 to the two switched sockets 14, 16 on each front support housing 12. In this case, a first one of the ring mains 34 is designated as essential' for equipment such as a fridge, a freezer, an alarm, a recording device, and/or a hot water / heating boiler which should, ideally, not be switched off except in emergencies. The second ring main 36 is designated as non-essential' for equipment such as a television, a radio, a kettle, a toaster, a gaming console, a computer and/or computer peripherals and accessories, which can be switched off at more or less any time without detrimental impact.
To identify which ring main 34, 36 feeds which switch socket 14, 16, each switched socket 14, 16 includes a unique indicator 38. The indicator 38 of the non-essential switched socket 14, 16 in this case includes three indicator elements 40, 42, 44, being a legend adjacent to a switch 46 of the socket 16 stating Non-Essential', a first colour applied to the switch 46, in this case being green, and a character also applied to the switch 46, in this case being N'. Fewer or more indicators are feasible.
The indicator 38 of the essential switched socket 14 also includes three indicator elements 48, 50, 52, being a legend adjacent to the switch 54 stating Essential', a second colour applied to the switch 54, in this case being red, and a character applied to the switch 54, in this case being E'. Again, fewer or more indicators are feasible.
The master switch unit 18 also preferably includes the same indicator or indicators as the non-essential switched socket 16 so as to provide an easy visual association for the user.
Alternatively or additionally, other indicators or indicator elements can be considered, such as different legends, colours and characters.
In use, the essential and non-essential switched sockets 14, 16 are easily distinguishable, prompting a user to plug non-essential electrical equipment into one or more of the non-essential switched sockets 16, and essential electrical equipment into one or more of the essential switched sockets 14. The local switches 46, 54 on the front support housing 12 allow each socket 14, 16 to be controlled independently by a user. However, the master switch unit 18 via the contactor 28 allows the second ring main 36 to be switched off, thereby halting an electricity supply to all of the non-essential switched sockets 16 on each front support housing 12. Consequently, all electrical equipment plugged into the non-essential switched sockets 16 is immediately deenergised and electrically isolated from the first ring main 34.
The first ring main 34 cannot be switched off by the master switch unit 18, and therefore an electricity supply from the consumer unit 30 via the contactor 28 to the first ring main 34 and the essential equipment remains uninterrupted.
Although the front support housing 12 supports two switched sockets 14, 16, it may support more than two switched sockets. In this case, two or more essential and/or non-essential switched sockets 14, 16 may be provided.
Alternatively, it is feasible that the front support housing 12 may only support non-essential switched sockets 16. In this case, the second non-essential ring main 36 may supply electricity to a combination of units, one or more of which have the essential and non-essential switched sockets 14, 16 and one or more of which may have only the non-essential switched sockets 16.
Referring now to Figures 4 to 6, a second embodiment of the socket apparatus 10 will now be described. Like references refer to like parts, and further detailed description is omitted.
The socket apparatus 10 of this embodiment again comprises the front support housing 12, the two essential' and non-essential' switched sockets 14, 16, and the master switch unit 18. However, as can be appreciated from Figure 4, the contactor is dispensed with in favour of a step-down transformer 56, and a low-voltage, being 12 volt for example, signal circuit 58 is provided in place of the second non-essential ring main.
The consumer unit 30 provides a supply of electricity directly to the single common ring main 60. The essential and the non-essential switched sockets 14, 16 are therefore both supplied with mains voltage electricity by the single ring main 60. Consequently, unlike in the first embodiment, only one Live terminal 62 and one Neutral terminal 64 for the incoming ring main 60 need be provided to supply mains electricity to both switched sockets 14, 16.
A local on-board switching device 66 controllable by the master switch unit 18 via the low-voltage signal circuit 58 is provided at a rear of the front support housing 12. In this case, the switching device 66 includes a PCB 68 mounted behind one or both switched sockets 14, 16 and a fused relay 70 on the PCB 68 is utilised to interrupt the mains electricity supply to the non-essential switched socket 14, 16.
In use, the relay 70 of the local on-board switching device 66 is normally energised thus allowing mains electricity to be supplied by the consumer unit 30 to the or each non-essential switched socket 16 on the ring main circuit 60. Once the master switch unit 18 is operated, the relay 70 is deenergised causing the mains electricity supply to only the non-essential switched socket 16 to be interrupted. The mains electricity supply to the or each essential switched socket 14 remains unaffected. Consequently, the electrical devices attached to the non-essential switched sockets 16 can be electrically isolated and thus deenergised.
Referring to Figures 7 to 9, a third embodiment of the socket apparatus 10 will now be described. The third embodiment is similar in some respects to that of the second embodiment. As before, like references refer to like parts, and further detailed
description is omitted.
In this embodiment, instead of the low-voltage signal circuit, a wireless connection is utilised between the master switch unit 18 and the or each non-essential switched socket 16. To this end, the transformer of the second embodiment is dispensed with, since the master switch unit 18 is mains powered directly or indirectly from the consumer unit 30.
The master switch unit 18 includes a wireless transmitter 72, which may utilise radio frequency, microwave frequency, Bluetooth RTM, or any other suitable wireless data transmission protocol.
The PCB 68 of the local on-board switching device 66 is again utilised and, as well as the fused relay 70 or another suitable switching element, a wireless receiver 74 is provided for operating the switching element 70.
In use, the switching element 70 of the local on-board switching device 66 is normally energised thus allowing mains electricity to be supplied by the consumer unit 30 to the or each non-essential switched socket 16 on the ring main circuit. Once the master switch unit 18 is operated, a control signal is outputted by the wireless transmitter 72 and received by the wireless receiver 74 of the local on-board switching device 66. The local switching element 70 is deenergised or switched, causing the mains electricity supply to only the non-essential switched socket 16 to be interrupted. The mains electricity supply to the or each essential switched socket 14 remains unaffected, as in the second embodiment. Consequently, the electrical devices attached to the non-essential switched sockets 16 can be electrically isolated and thus deenergised.
The socket apparatus 10 described in the above embodiments can conveniently be provided as a kit of parts for retro fitting to an existing consumer unit.
One or more of the sockets need not necessarily be locally switchable, and thus one or more of the local switches may be dispensed with. II may be feasible that the non-essential sockets are only switchable via the master switch unit.
Furthermore, the master switch unit, although preferably permanently mounted directly to a wall or other surface, may be freestanding.
It is thus possible to provide a dedicated circuit for non-essential electrical devices and appliances such that, by use of a single, typically wall-mountable, master switch at a convenient location, the entire group of devices or appliances can be electrically isolated and reenergised as necessity dictates. This significantly reduces wasted energy and thus environmental impact. The socket apparatus is simple to install in a new build or retro-fit to an existing building. The apparatus comprises a small number of parts, enabling cost-effective manufacture, and a plurality of indicators ensures a user is unlikely to make a mistake when plugging in an electrical device or appliance.
The embodiments described above are provided by way of examples only, and various other modifications will be apparent to persons skilled in the art without departing from the scope of the invention as defined by the appended claims.
