    [0003]
    [0004] SECTOR OF THE TECHNIQUE
    [0005]
    [0006] The present invention relates to valve arrangements, and more specifically to valve arrangements for gas burners.
    [0007]
    [0008] PREVIOUS STATE OF THE TECHNIQUE
    [0009]
    [0010] Valve arrangements are known for regulating the gas flow of a gas burner, wherein an electromagnetic valve, controlled by a control unit, is disposed between a manual gas valve and the gas burner, the electromagnetic valve acting as a valve for security. These valve arrangements comprise, for example, a temperature sensor calibrated with a maximum temperature, electrically connected to the control unit, to limit a temperature related to a cooking process in the gas burner. The control unit acts on the solenoid valve to cut off the gas flow when the temperature sensor detects an overheating in the cooking process.
    [0011]
    [0012] KR2015099080A describes a valve arrangement for a gas burner comprising a manual gas valve comprising a body comprising a gas inlet conduit, a gas outlet conduit adapted to drive the gas towards the burner, and a manual actuator for opening or closing the gas flow through the gas valve, and an electromagnetic valve comprising a movable closing member that allows to open or close a gas passage to the burner, the electromagnetic valve being fed through an electrical circuit , and the electrical circuit being connected to at least one sensor.
    [0013] EXHIBITION OF THE INVENTION
    [0014]
    [0015] The object of the invention is to provide a valve arrangement for a gas burner, as defined in the claims.
    [0016]
    [0017] The valve arrangement of the invention comprises a manual gas valve comprising a body comprising a gas inlet conduit, at least one gas outlet conduit adapted to drive the gas towards the burner, and a manual actuator for opening or closing the gas flow through the gas valve, and also comprises an electromagnetic valve comprising a movable closing member that allows to open or close a gas passage towards the burner, the electromagnetic valve being fed through an electrical circuit, and the electrical circuit being connected to at least one sensor.
    [0018]
    [0019] The solenoid valve of the valve arrangement is arranged in the body of the gas valve, the manual actuator of the gas valve being coupled with a rotary gas flow regulator element communicated with the outlet conduit, the manual actuator of the gas valve to move axially to move the closing member of the electromagnetic valve by opening the gas passage, said gas passage communicating the inlet conduit and the regulating element, the manual gas valve comprising a reduced gas flow channel which fluidly communicates the inlet conduit with the regulating element regardless of the position in which the closing member is, such that when the closing member of the electromagnetic valve passes to a closing position due to an abnormal situation detected at Through the sensor, the gas burner is still on with the flow of gas passing through the pipe l.
    [0020]
    [0021] The valve arrangement of the invention, by integrating an electromagnetic valve and a reduced gas flow channel in the same manual gas valve, allows to manage the gas flow to the gas burner, reducing it, when the cooking process established in said gas gas burner is unattended. For this, the valve arrangement detects an anomalous situation, such as an absence of casserole in the gas burner, an excess of temperature, or an absence of the user in the vicinity of the gas burner, by means of a sensor, and reduces the flow of gas in said gas burner at a value that does not pose a risk.
    [0022] This is also obtained with a valve arrangement with a smaller number of parts, since the use of electromagnetic valves with reduced gas flow channels integrated and controlled by a control unit is avoided.
    [0023]
    [0024] These and other advantages and features of the invention will become apparent in view of the figures and the detailed description of the invention.

    [0046] DETAILED EXHIBITION OF THE INVENTION
    [0047]
    [0048] Figure 1 shows a schematic view of an embodiment of the valve arrangement 300 for a gas burner 200 according to the invention. Said valve arrangement 300 comprises a manual gas valve 100 comprising a body 10 comprising a gas inlet duct 11, an outlet duct 12 of the gas adapted to drive the gas towards the burner 200, and a manual actuator 20 to open or closing the gas flow through the gas valve 100. The valve arrangement 300 also comprises an electromagnetic valve 40 comprising a movable closing member 41 that allows to open or close a gas passage 13, arranged in a housing of the body 10 of the manual gas valve 100, towards the burner 200, the electromagnetic valve 40 being fed through an electrical circuit 51, and the electrical circuit 51 being connected to a sensor 60 which in this embodiment is arranged in series.
    [0049]
    [0050] The gas valve 100 is a gas valve in which the solenoid valve 40 is disposed in the body 10 of said gas valve 100, the inlet conduit 11 of the gas being fluidly communicated with the electromagnetic valve 40. The manual actuator 20 of the gas valve 100 is coupled with a regulating element 30 of rotary gas flow , conical or cylindrical for example, fluidly communicated with the outlet duct 12. The regulating element 30 is adapted to regulate the flow of incoming gas from the inlet duct 11 of the gas, and through the passage of gas 13 to the outlet duct 12 depending on its angular position, for which it comprises in this embodiment an inlet port in the lower part, and at least one outlet hole that fluidly communicates with the outlet duct 12 of the gas valve 100. The passage of gas 13 is in this embodiment a hole in the body 10 of the gas valve 100, which fluidly communicates the inlet conduit 11 of the gas and the regulating element 30, through a c chamber 15 arranged below the lower part of the regulating element 30, where the inlet port for the gas is arranged, and after the passage of gas 13, in the direction of the gas flow.
    [0051]
    [0052] The manual actuator 20 of the gas valve 100 is configured to move axially to move the closing member 41 of the solenoid valve 40 by opening the gas passage 13. To this end, the manual actuator 20 comprises an extension 23, which can be a shaft coupled to manual actuator 20 and tightly passing through regulator 30.
    [0053]
    [0054] The manual gas valve 100 comprises a reduced gas flow channel 14 arranged in this embodiment through the closing member 41 in the direction of the gas flow. Said channel 14 fluidly communicates the inlet conduit 11 with the regulating element 30 through the chamber 15, such that when the closing member 41 of the electromagnetic valve 40 passes to a closed position due to an abnormal situation detected at through the sensor 60, the gas burner 200 is still fed with gas and ignited, with a reduced gas flow to a certain value passing through the channel 14, the passage of said channel 14 defining the value of the reduced gas flow. The reduced gas flow after passing through the channel 14 will feed the burner 200 by flowing through the chamber 15, the regulating element 30, and through the outlet duct 12 of the gas.
    [0055]
    [0056] The manual actuator 20 is in this embodiment a rotary drive shaft between an initial turning position and a final turning position, the regulating element 30 being coupled to the manual actuator 20 and defining an initial turning position and a final turning position of said regulating element 30, and thereby defining a regulation of the gas flow in the initial position and in the final rotation position, which in this embodiment is for example a regulation without gas flow or OFF, and a regulation of minimum gas flow or MIN, respectively. Between these two positions is an angular position, for example at 90 °, for the maximum gas flow or MAX. The manual actuator 20 has a control 21 attached at one end and external to the body 10 of the gas valve 100, which allows the user to manually use said gas valve 100. Between the control 21 and the body 10 is in this embodiment, a spring 22 is provided, said spring 22 allowing the manual actuator 20 to return to an initial rest position, and therefore of the control 22, when the user stops pressing said manual actuator 20 and therefore stops moving it axially.
    [0057]
    [0058] The structure of the electromagnetic valve 40 can be for example like that of the electromagnetic valve described in the patent application of the same applicant EP3222914A1, which is incorporated by reference. As shown in Figure 1, the solenoid valve 40 comprises an electromagnet comprising a core 42, a reel (not shown in the figures) embedded in the core 42, and a winding 43 disposed on the reel and around the core 42 The electromagnetic valve 40 also comprises a metallic mobile armature 45 coupled to the closing member 41, and a spring 44 to return the closing member 41 together with the mobile armature 45 to the closed position of the gas passage 13. The winding 43 it comprises a phase wire connected to a phase connector, and a ground wire (not shown in the figures), electrically connected to the electrical circuit 51.
    [0059]
    [0060] The electrical circuit 51 is connected to an electrical supply source 50, so that the solenoid valve 40 can be electrically powered. In turn, the sensor 60 comprises an electrical contact 61 that acts as a switch in the electrical circuit 51, and opens said electrical circuit 51 when an abnormal situation occurs, as will be described later, preventing the power supply of the electromagnetic valve 40 through said electrical supply source 50. The electrical supply source 50 is in this embodiment a thermocouple disposed next to the burner 200. The reduced gas flow passing through the channel 14 is preferably of a value between the MIN minimum gas flow and MAX maximum gas flow of gas valve 100, depending on the heat output of gas burner 200, and it is sufficient to heat the thermocouple so that said thermocouple supply sufficient electric current to the solenoid valve 40 to open it. Once the solenoid valve 40 is electrically powered, the core 43 of the electromagnet can attract the mobile armature 45, and with said movable armature 45 the closing member 41 is attracted, which moves towards its opening position and allows the passage of gas 13.
    [0061]
    [0062] In the embodiment of the valve arrangement 300 shown in Figure 1, the sensor 60 is a temperature sensor disposed in the gas burner 200 under a cooking vessel 70 and in contact with its bottom. The electrical contact 61 is a bimetallic contact that is in contact with the bottom of the container 70, and that is heated as the burner 200 is with the flame burning. In this exemplary embodiment, the contact 61 is calibrated for a threshold temperature, so that when said threshold temperature is reached in the container 70, the bimetallic contact 61 is activated and opens the electrical circuit 51, ceasing to power the thermocouple 50 to the solenoid valve 40. Once this situation has been achieved, the core 43 of the solenoid of the solenoid valve 40 stops attracting the movable armature 45, and therefore stops attracting the closing member 41, said closing member 41 moving to its position of closing and closing the gas passage 13. The burner 200 is still supplied with gas in this situation with the reduced gas flow that allows the channel 14 to pass.
    [0063]
    [0064] In another embodiment of the valve arrangement 300 the sensor 60 is an absence detector of a cooking vessel 70 disposed on the burner 200, so that said sensor 60 is activated when there is no vessel 70 on said burner 200. In another embodiment of the valve arrangement 300 the sensor 60 is a detector of absence of people in the environment of the burner 200, so that said sensor 60 of presence of people is activated when there is no person in an environment of the burner 200 determined by said sensor 60 Thus, and with the different sensor configurations 60 described, the valve arrangement 300 offers a safety function against overheating, or a function of unattended gas burners, in which the regulated gas flow in the gas valve 100 is allowed manual towards the burner 200 when the solenoid valve 40 of said gas valve 100 is in the open position, and in which the gas flow is allowed to reduce acid defined by channel 14 when the solenoid valve 40 is in the closed position.
    [0065] Figure 1 shows the valve arrangement 300 where the gas valve 100 is closed. Manual actuator 20 is in the initial turning position in a regulation OFF position without gas flow. The burner 200 has no flame, the thermocouple 50 does not generate electricity, and the solenoid valve 40 is not electrically powered, the gas passage 13 being closed by the closing member 41.
    [0066]
    [0067] Figure 2 shows in a schematic view the valve arrangement of Figure 1, where the gas burner 200 is ignited. To do this, the manual actuator 20 of the gas valve 100 is moved axially by pressing the control 21, and then said manual actuator 20 is rotated to rotate the regulating element 30. With the axial displacement of the manual actuator 20 the extension 23 displaces the closing member 41 of the solenoid valve 40 opening the gas passage 13. The flow of gas from the inlet duct 11 passes through the gas passage 13, and through the chamber 15 is introduced into the regulator element 30 by the inlet hole, and exits to the outlet duct 12, and therefore to the burner 200, by the at least one outlet port. A flame 210 is ignited in the burner 200 by manual means or by means of a spark generator (not shown in the figures), said flame 210 heating the thermocouple which is the power source 50 of the solenoid valve 40. Progressively heats the thermocouple 50 generating more electricity until the solenoid valve 40 is able to keep the closing member 41 and the gas passage 13 open displaced.
    [0068]
    [0069] Figure 3 shows in a schematic view the valve arrangement of Figure 1, wherein the manual actuator 20 is released by the user after the ignition of the flame 210 in the gas burner 200, the electromagnetic valve 40 is electrically powered by the thermocouple 50, and sufficient time has elapsed for said solenoid valve 40 to keep the gas passage 13 open only with the power supply supplied by said thermocouple 50. The spring 22 returns the manual actuator 20 to its original position, and the extension 23 of the manual actuator 20 stops pushing the closing member 41. The gas flow to the burner 200 is the one defined by the user when turning the manual actuator 20, and therefore turning the regulating element 30, to a position between the initial turning position and the final turning position. The flame 210 of the burner 200 progressively heats the container 70.
    [0070] Figure 4 shows in a schematic view the valve arrangement of Figure 1, wherein the sensor 60 detects the threshold temperature for which it is defined, the bimetallic contact 61 opens, and therefore the sensor 60 is activated, and as consequently the electrical circuit 51 opens. In this way, the electromagnetic valve 40 is no longer electrically powered, the electromagnet of said electromagnetic valve 40 stops attracting the mobile armature 45, and the closing member 41 returns to its closed position by closing the gas passage 13. The gas it flows to the burner 200 through the reduced gas flow channel 14 disposed in this embodiment in the closing member 41 of the solenoid valve 40. The flame 210 is reduced in the burner 200, but has a sufficient calorific value to heat the thermocouple 50, and that said thermocouple 50 generates enough electricity to electrically power the solenoid valve 40, when the sensor 60 detects a temperature in the container 70 below the threshold temperature, it is deactivated and the electrical circuit 51 is closed again. The gas valve 100 in which the solenoid valve 40 is housed can be a standard gas valve, without modification of any kind on a manual gas valve comprising a safety solenoid valve with an open position and a closed position in which there is no gas flow to the gas burner.
    [0071]
    [0072] The valve arrangement 300 also allows a manual reset for the return of the gas valve 100 to the situation prior to the opening of the electrical circuit 51 by the sensor 60, when for example the reduced gas flow is not sufficient for the Thermocouple 50 generates enough electricity to power the solenoid valve 40 and said valve 40 opens the gas passage 13, attracting the mobile armature 45 towards the core 42 of the electromagnetic solenoid of the solenoid valve 40. The rearmament is in this embodiment a voluntary act of user who presses the manual actuator 20 again by contacting the mobile armature 45 and the core 42 of the electromagnet, so that if the temperature already detected by the sensor 60 is below the threshold temperature, and the contact 61 closes the circuit electrical 51, the electricity generated by the thermocouple 50 is sufficient for the solenoid valve 40 to be able to keep the armature in contact mobile 45 and the core 42 of the electromagnet, and the gas passage 13 is kept open. In this embodiment of the valve arrangement 300, the rearmings cannot be accidental.
    [0073]
    [0074] The valve arrangement 300 may have warning means (not shown in the figures), so that, for example, the user knows when to reassemble the gas valve 100. The alert means can comprise, for example, a led light that turns on when the sensor 60 has been activated, opening the electrical circuit 51, and reducing the gas flow to the burner 200, and a led light that comes on when the sensor 60 has been deactivated and the user can then rearm the gas valve 100 and return to the previous gas flow.
    [0075]
    [0076] Figure 5 shows a schematic view of a second embodiment of the valve arrangement 300 according to the invention. In this second embodiment, the reduced gas flow channel 14 is disposed in the body 10 of the gas valve 100, fluidly communicating the inlet conduit 11 of the gas with the chamber 15. The other features of the valve arrangement 300 are the same as those described in the first embodiment, showing a situation as described in Figure 4 of said first embodiment of the valve arrangement 300.
    [0077]
    [0078] In the embodiments of the valve arrangement 300 described above, no external power supply is necessary, nor any control unit that performs an electronic management on the solenoid valve 40, so that the valve arrangement 300 is fully autonomous.
    [0079]
    [0080] Figure 6 shows a schematic view of a third embodiment of the valve arrangement 300 according to the invention. In this third embodiment the power supply source 50 of the solenoid valve 40 is the power supply network or is a direct current power supply, such as a battery, and said power supply is continuous and instantaneous. Depending on the configuration of the solenoid valve 40, this external power supply allows, for example, that the mobile armature 45, and therefore the closing member 41, travel and open the gas passage 13 without delays.
    [0081]
    [0082] Figure 7 shows in a schematic view a fourth embodiment of the valve arrangement 300 of the invention that differs from the embodiment of Figure 1 in that it also comprises a timer 80. The function of this timer 80 is to temporarily override the security offered by the valve arrangement 300 when, for example, in an embodiment of said valve arrangement 300 in which the sensor 60 is a temperature sensor that detects a threshold temperature, the user wants to cook with a high calorific value in the burner 200. In this example, if the valve arrangement 300 does not comprise the timer 80, when the threshold temperature is reached, the electromagnetic valve 40 is no longer electrically powered, and the burner 200 is fed with the reduced gas flow passing through channel 14. This situation is maintained until the temperature detected by the sensor 60 is below the threshold temperature, and the gas flow in the burner 200 returns to the value defined by the user before the anomalous situation is detected. With the timer 80, and at the user's request, the reduction of the gas flow in the burner 200 is canceled for a predefined time, the user defined gas flow being maintained with the manual actuator 20.
    [0083]
    [0084] To perform this function, the timer 80 is coupled to the manual actuator 20 of the gas valve 100 mechanically. In the embodiment shown, the timer 80 is arranged externally to the gas valve 100, but in other embodiments it may be integrated with said gas valve 100, the timer 80 being arranged for example concentric to the manual actuator 20, and between the control 21 and the body 10. These different arrangements allow said timer 80 to be activated when the manual actuator 20 is pressed and moved axially. On the other hand, said timer 80 comprises an electrical contact 81 by means of which it is electrically connected to the electrical circuit 51, in this embodiment being connected in parallel with the contact 61 of the sensor 60. Thus, when the sensor 60 detects the temperature The threshold is activated by opening the contact 61 the electrical circuit 51, and the user presses the manual actuator 20 activating the timer 80, closing the contact 81 said electrical circuit 51 for a predetermined time.
    [0085]
    [0086] In the valve arrangement 300 shown in Figure 7, the sensor 60 is activated because it detects the threshold temperature in the container 70, and the electrical circuit 51 open, the manual actuator 20 is not pressed and therefore the timer 80 is not activated , the timer 80 being electrically disconnected from the electrical circuit 51. Thus, the gas passage 13 is closed, the electromagnetic valve 40 is not electrically powered, and the burner 200 is fed with the reduced gas flow passing through the channel 14.
    [0087]
    [0088] Figure 8 shows in a schematic view the valve arrangement of Figure 7, where the sensor 60 is activated, because it is understood that it still detects the threshold temperature and the electrical circuit 51 is open. On this occasion the user has decided to intervene by pressing the manual actuator 20, displacing it axially, opening the gas passage 13 and activating the timer 80, closing the electrical contact 81 the electrical circuit 51. The electromagnetic valve 40 is electrically powered and keeps the gas passage 13 open, so that the Burner 200 is fed with the gas flow that the user had defined with the manual actuator 20 by regulating the regulator element 30.
    [0089]
    [0090] Figure 9 shows in a schematic view the valve arrangement of Figure 7, where after the situation of the valve arrangement 300 shown in Figure 8 and described above, the user releases the manual actuator 20 after activating the timer, turning said actuator manual 20 to its original position due to the spring 22, and being the solenoid valve 40 electrically powered by the thermocouple 50 and with the gas passage 13 open, the burner 200 is still fed with the gas flow that the user had defined, until the predetermined time defined in timer 80 ends, and the gas flow in burner 200 is reduced.
    [0091]
    [0092] The timer 80 can be a pneumatic retarder, which once pressed and depending on the air outlet defined in the retarder, determines a predetermined time, or it can be an electronic timer in which pressing the manual actuator 20 activates the timer, said means timer being arranged to determine different predetermined times.
