Definitions

  • the present invention relates to a gas burner heater.
  • a heating device of the type consisting of at least three burners respectively connected to a common gas supply pipe, each burner being able to be independently supplied with gas via an opening / closing closable connection.
  • the control means opening / closing the connection of each burner controlling, during the passage of a power stage N to a selected power stage P, the opening of the connection of the burner (s) to be lit upstairs of selected power P and at least the opening of the connections of the set of burners separating a burner ignited at the power stage N a burner to be ignited in the power stage P to allow automatic ignition of the flame of each burner by contacting the air / gas mixture expelled from said burner with the flame of an adjacent burner until ignition of the burner to ignite at the selected stage P then the selective closure of the connections of the burners not included in the combination corresponding to the selected power stage P.
  • Gas burners are nowadays widely used, in particular for the heating of the air, in particular in the buildings of breeding.
  • the major disadvantage of these burners lies in their reduced power range. Indeed, their operation, based on the ignition of an air / gas mixture, requires respect for the proportions of the components in the mixture. It is therefore impossible to vary significantly the amount of gas in the mixture without the risk of extinguishing the flame.
  • the trend today is to use powerful burners that are frequently switched between On and Off positions for temperature control. This results in user comfort problems due to the inertia of its burners.
  • An object of the present invention is to overcome the aforementioned drawbacks by proposing a heating device whose design allows a variation of the power over a wide range, the value of the bearings between power stages being freely selectable by the user so to offer a large number of possibilities to the latter.
  • Another object of the present invention is to provide a heating device whose number of burners, although reduced, provides a power variation within a wide range while ensuring optimal operation and perfectly safe the flame control device.
  • Another object of the present invention is to provide a heating device of simple design and whose number of parts can be reduced without harming the safety of the assembly.
  • Another object of the present invention is to propose a heating device having a large number of power stages for a given number of burners, each power stage corresponding to a predetermined combination of the burners arranged in any way in the device. .
  • the invention relates to a heating device of the type consisting of at least three burners respectively connected to a common gas supply pipe, itself connected to a gas supply source, each burner being able to be independently supplied with gas via a shut-off connection with controlled opening / closing between the gas supply source and the burner, the burners being of at least two types differing in their heating power, these burners being associated in different selectable combinations each corresponding to a power stage, the opening / closing control means of the connection of each burner commander, during the passage of a power stage N to a selected power stage P , the opening of the connection of the burner (s) to be ignited to the selected power stage P and at least the opening of the connections of all the burners separating a burner ignited at the power stage N from a burner to be ignited at the power stage P to allow an automatic ignition of the flame of each burner by contacting the air / gas mixture expelled from said burner with the flame of an adjacent burner until ignition of the burner to be ignited at the selected stage P and the selective closure of the
  • the passage of a power stage to another power stage can be carried out without having to multiply the number of flame control devices on the burners.
  • the device Flame control can be common to all burners and activated by any of the burners because, when switching from one power stage to another, all burners operate.
  • the probe in the case of a flame control device operating by ionization. This ignition of all the burners during the transitional period thus allows to go from one power stage to another without having any common burner on between the two stages thus increasing the number of combinations and as a result of possible power steps.
  • the heating device which is the subject of the invention, consists of burners 1 connected to a rigid gas supply line 2, generally of metal, itself connected to a gas supply source 3. which can be any. The whole forms what could be called a gas burner ramp 1.
  • the burners 1 act conventionally by combustion of an air / gas mixture.
  • These burners 1 can be atmospheric or dynamic type. In such a device, these burners 1 will be at least three in number.
  • Each burner 1 comprises, in a manner known per se, a duct comprising at least one primary combustion air inlet and enclosing at least the gas injector and an air / gas mixing chamber, this duct opening into a combustion chamber mixing air / gas.
  • the duct contains, between the injector and the air / gas mixing chamber, a venturi element. The detail of such burners will not be provided because many examples of embodiment of burners can be found in the literature.
  • the heating device object of the invention, there are preferably two types of burners, namely a burner, said master, equipped with an ignition device 4 of air / gas mixture and burners 1, said slaves , which are different from the master burner in that they are free of ignition device of the air / gas mixture.
  • the ignition device 4 of the air / gas mixture will not be described in detail since it may be constituted in a manner known per se of an electrical device of resistor, spark or other type, a night light or the like.
  • Each heating device comprises a device 11 for controlling the flame. This device 11 for controlling the flame is thus common to all the burners.
  • This device 11 for controlling the flame may consist of an optical device, an ionization device, an infrared device or any other means which ensures, upon extinction of the flame, the closure of the flame. supplying the common gas supply pipe from the gas supply source by means of an appropriate closing valve.
  • this device 11 is an ionization device consisting of a probe and a metal rod to cap the middle burner and extending along each of the burners adjacent to the middle burner. The cooperation of this device 11 for controlling the flame with the burner control means will be described below.
  • Each burner 1, master or slave, is connected to the gas supply source 3 via the common gas supply pipe 2 and a tap on said pipe 2.
  • Each connecting portion 5, made between the source 3 of gas supply and a burner 1 is provided with a member 6 such as a solenoid valve opening or closing the connection 5 between the burner 1 and the source 3 gas supply .
  • This opening / closing of the link 5 is controlled by means of a suitable control device according to the selected power stage.
  • the heating device comprises a plurality of burners 1. Among these burners, there are at least two types of burners 1 differing in their heating power. Preferably, the burner 1 of lower power is disposed between two other burners 1.
  • burners are operatively associated in any predetermined combinations selectable at will and randomly for example by means of a programmer, each combination corresponding to a power stage.
  • a heating device having four burners with different heating power.
  • the first stage corresponds to the operation of the master burner of lower power
  • the second stage of power to the combination of the lower power burner with the power burner immediately above ...
  • the last stage corresponding to a combination where the set of burners operate, that is to say are on.
  • the heating device therefore further comprises means for selecting a power stage corresponding to a predetermined combination of burner (s) in operation among a plurality of stages.
  • These selection means may be constituted by a programmer.
  • B1, B2, B3, B4 it is possible to define a first power stage corresponding to an air / gas mixture feed of B1, the connections of the other burners. remaining closed. It can be defined a second power stage in which only the burner B3 of different power of the burner B1 is lit. It can be defined other combinations, the total number of combinations being at most equal to 2 x , x corresponding to the number of burners of the installation.
  • the means 7 for opening / closing control of the connection of each burner control during the passage of a power stage N to a new stage of any power P selected, opening all of the connections 5 of the burners 1 to allow, by automatic ignition of the flame of a burner by contacting the air / gas mixture expelled from the burner with the flame of an adjacent burner , the ignition of all the burners then the selective closing of the connections 5 of the burners not included in the combination corresponding to the new selected power stage.
  • a device with 4 burners B1 to B4, of different power arranged side by side, 0 corresponds to an open connection of the burner, F to a closed connection.
  • the power stage N corresponds to a stage where only the burner B1 operates while the power stage P corresponds to a stage where only the burner B3 operates.
  • Power stage B1 B2 B3 B4 NOT 0 F F F Transition stage B1 B2 B3 B4 0 0 0 0 0 Power stage B1 B2 B3 B4 P F F 0 F
  • This solution makes it possible to dispense with storage means of the burner combinations coupled to the means 7 for controlling the opening / closing of the links. Thus, between each passage from one power stage to another, all the burners are operated by automatic opening of the links 5. On the other hand, this solution makes it possible to guarantee the activation of the control device 11 of the control device. the flame by any of the burners, regardless of the selected power level. Indeed, when the selected power level corresponds to the ignition of a low-power burner and this grinder is opposite the burner lit on the N-1 power stage, it is not guaranteed.
  • the The flame control has a sufficient temperature after the burners have been extinguished once the transition has been made.
  • operating all the burners during the transition period and the passage of a power stage to another allows to ensure that the flame control device is warmed up or to generate sufficient heat to allow optimal operation of this flame control device. It thus becomes possible, thanks to this mode of operation, to go from one power stage to another by choosing a first burner positioned at the N-1 power stage and a burner positioned far away from the first burner. the power stage N, this second burner being a burner of weak power.
  • the shutoff member 6 controlled opening / closing of the connection 5 between a burner 1 and the source 3 of gas supply is a solenoid valve.
  • the opening / closing of the solenoid valves can be controlled by means of electrical signals emitted from information emanating from a control unit, such as a microprocessor. This control unit manages the information relating to the selected power stage to determine the links to be opened or respectively closed.
