Abstract

A gas fuelled appliance, such as a live fuel effect gas fire, comprises a gas burner 1 which is supplied with gas via an electrically controlled gas flow control valve 4 provided with an electronic controller 5 for presetting the required gas flow and for causing the preset gas flow to be varied in a random or pre-programmed manner in order to obtain a more realistic varying live fuel effect. A further burner may provide the main heat output. Alternatively the voltage to the gas valve of a cooker hob may have a pre-programmed variation to effect stirring of a soup or sauce. <IMAGE>

Description

Gas Fuelled Appliances This invention relates to gas fuelled appliances and more specifically to gas fuelled appliances which incorporate electrically controlled gas flow control valves.
It is becoming increasingly popular to incorporate electrically controlled gas flow control valves in, for example, gas fires and gas cookers, and the use of such valves enables the appliances to be provided with additional facilities not previously possible with mechanically operated gas valves.
It is known to incorporate an electrically controlled gas flow control valve in so-called live fuel effect gas fires which are provided with a simulated fuel bed of coals or logs through which gas flames extend in order to give the appearance of a "real" coal or log fire as the case may be. Such fires can be very realistic but suffer from the disadvantage that the flame pattern never varies and the effect is, therefore, not as realistic as it could be.
It is an object of the present invention to provide a gas fuelled appliance, such as a live fuel effect gas fire, which incorporates an electrically controlled gas flow control valve and which enables a more realistic varying live fuel effect to be obtained.
According to the present invention there is provided a gas fuelled appliance comprising a gas burner and an electrically controlled gas flow control valve for controlling gas flow to said burner, electrical control means being provided operable on said valve for causing the gas flow to said burner to be varied in a random or pre-programmed manner.
In this way, the gas flow to a gas burner of, for example, a live fuel effect gas fire, may be varied in a random or pre-programmed manner to afford a more realistic varying live fuel effect.
In carrying out the invention, it may be arranged that the setting of said valve is manually adjustable, said electrical control means being operable for causing the manually adjustable setting to be varied in said random or pre-programmed manner.
In one preferred arrangement according to the present invention the gas fuelled appliance will take the form of a live fuel effect gas fire, in which said gas burner is effective for producing a live fuel effect, in which case a further gas burner may be provided for generating the main heat output of said appliance.
In a second preferred arrangement according to the present invention the gas fuelled appliance will take the form of a gas cooker, said gas burner preferably being disposed in a cooking hob thereof.
An exemplary embodiment of the invention will now be described reference being made to the accompanying drawing which is a block schematic diagram of a gas burner and control arrangement for use in a gas fuelled appliance according to the present invention.
The gas burner and control arrangement shown in the drawing is adapted to be incorporated in a live fuel effect gas fire in order to obtain a more realistic live fuel effect. The gas burner shown may constitute the only gas burner of the fire in which case it will afford the main heat output of the fire as well as affording the live fuel effect, or it may form part of a gas burner assembly, a main gas burner (not shown) being provided for generating the main heat output of the fire.
In the drawing, a gas burner 1 is shown connected by a gas supply conduit 2 to a gas supply 3, an electrically controlled gas flow control valve 4 being interposed in the gas supply conduit 2. The electrically controlled gas valve 4 may take any convenient form and may be a proportional control valve or a modulating (on-off) type valve.
The electrically controlled gas valve 4 is controlled by an electronic controller 5 via a valve power driver 6, the electronic controller 5 effectively generating the electrical control voltage which is applied to the gas valve 4 to effect the required gas flow setting thereof.
The electronic controller 5 is provided with a first input 7 which is manually set in accordance with the required gas flow setting of the gas valve 4, and a second input 8 which is fed from a random signal generator 9. The random signal generator 9, which may take any convenient form, generates a randomly varying signal which, when applied to the electronic controller 5 causes the output thereof, the average level of which is determined by the input 7, to be varied in a random manner so that the gas flow to the gas burner 1 is also varied in a random manner. The random signal generator 9 is provided with an input 10 for presetting the effective range that the gas flow to the gas burner 1 is varied by.Instead of the random signal generator 9, a pre-programming arrangement which has a relatively long repeat interval may be provided for generating the input 8 to the electronic controller 5.
Although ideally suited for use in live fuel effect gas fires, the gas burner and control arrangement described with reference to the accompanying drawing may also be used in gas cooking appliances, in which, for example, the gas burner 1 forms part of the cooking hob thereof. Normally, in a gas cooking appliance, when a particular burner setting has been chosen, that setting remains fixed. However, in accordance with the present invention it is envisaged that the control voltage applied to the gas valve 4 in order to set the gas flow thereof is varied over a restricted range to vary the gas flow to the gas burner 1. It is envisaged that this could be used, for example, to afford automatic stirring of soup, sauces, etc. by pre-programming the control voltage in accordance with a preset algorithm whereby the heat to a saucepan, for example, is successively increased and decreased to effect the required stirring. A pan sensor may also be provided for sensing the presence of a pan and for reducing gas flow when the pan is lifted away from the gas burner 1.
