Definitions

  • the present invention relates to gas cocks with a safety valve for a gas cooking appliance, and to gas cooking appliances incorporating said gas cocks.
  • Gas cocks with a safety valve for a gas cooking appliance are known.
  • Said gas cock comprises a body comprising a gas inlet conduit and at least one gas outlet conduit, a regulating element suitable for regulating the incoming gas flow from the safety valve to the outlet conduit depending on the angular position thereof, the regulating element being arranged in a housing of the body fluidically communicated with the safety valve and with the outlet conduit, and a drive shaft comprising a manually operable main shaft, said main shaft being rotatable between an initial rotation position and a final rotation position, and axially movable for acting on a transmission element for opening the safety valve, the regulating element rotating integrally with said main shaft.
  • gas cocks provided with a safety valve and which can be adapted to supply different types of gas.
  • a gas cock is described in document WO 2012/080054 A2 , which discloses the preamble of claim 1.
  • the object of the invention is to provide a gas cock with a safety valve for a gas cooking appliance, and a gas cooking appliance incorporating said gas cock, as defined in the claims.
  • the gas cock of the invention comprises a body comprising a gas inlet conduit and at least one gas outlet conduit, a regulating element suitable for regulating the incoming gas flow from the safety valve to the outlet conduit depending on the angular position thereof, the regulating element being arranged in a housing of the body fluidically communicated with the safety valve and with the outlet conduit, and a drive shaft comprising a manually operable main shaft, said main shaft being rotatable between an initial rotation position and a final rotation position, and axially movable for acting on a transmission element for opening the safety valve, the regulating element rotating integrally with said main shaft.
  • the regulating element is a rotating disk comprising at least one connection opening for regulating gas flow to the outlet conduit depending on the angular position thereof, said rotating disk being axially retained supported on a contact area of the housing of the body, the contact area comprising at least one outlet hole fluidically communicated with the gas outlet conduit, the rotating disk being configured for supplying different types of combustible gas depending on the angular positioning of said rotating disk with respect to the main shaft, and the drive shaft being configured for fixing the rotating disk in different angular positions with respect to the main shaft according to the type of combustible gas to be supplied.
  • the regulating element for regulating the gas flow rate is a frustoconical part that is form-fitted into a chamber of the body of the gas cock.
  • the regulating element sometimes seizes up when too much force is applied thereon by means of the manual drive shaft, and the gas passage may remain open, causing gas leak.
  • the contact surface in the pushing direction of the drive shaft is reduced, and a possible gas leakage is prevented.
  • the gas cock of the invention is suitable for supplying different types of gases without replacing or modifying the rotating disk but by simply positioning said rotating disk in different angular positions with respect to the main shaft of the drive shaft, depending on the type of gas to be supplied.
  • the drive shaft is configured for changing the relative position of the rotating disk with respect to the main shaft of said drive shaft. It is therefore an easy-to-implement solution with very few parts needed to enable changing the supply gas, which allows reducing the costs of the valve.
  • Figures 1 to 8 show an embodiment of the gas cock 100 with a safety valve 30 according to the invention, comprising a gas outlet conduit 12.
  • the gas cock 100 comprises a body 10 comprising a gas inlet conduit 11 which is fluidically communicated with the safety valve 30, and the gas outlet conduit 12 suitable for conducting the incoming gas to a burner (not shown in the drawings).
  • the gas cock 100 further comprises a regulating element suitable for regulating the incoming gas flow from the safety valve 30 to the outlet conduit 12 depending on the angular position thereof, the regulating element being arranged in a housing 51 of the body 10 which is fluidically communicated with the safety valve 30 and with the outlet conduit 12.
  • the gas cock 100 also comprises a drive shaft 40 comprising a manually operable main shaft 41, said main shaft 41 being rotatable along an angular path A between an initial rotation position and a final rotation position, and axially movable for acting on a transmission element 70 for opening the safety valve 30, the regulating element rotating integrally with said main shaft 41.
  • the regulating element is a rotating disk 20 comprising a connection opening 21 for regulating gas flow to the outlet conduit 12 depending on the angular position thereof.
  • Said rotating disk 20 is axially retained supported on a contact area 52 of the housing 51 of the body 10, the contact area 52 comprising an outlet hole 53 which is fluidically communicated with the gas outlet conduit 12.
  • the rotating disk 20 is configured for supplying different types of combustible gas depending on the angular positioning of said rotating disk 20 with respect to the main shaft 41, and the drive shaft 40 is configured for fixing the rotating disk 20 in different angular positions with respect to the main shaft 41 according to the type of combustible gas to be supplied.
  • the drive shaft 40 also comprises a transmission shaft 46 which pushes the transmission element 70 when it is moved axially, the rotating disk 20 being coupled to the transmission shaft 46, and said transmission shaft 46 being coupled to the main shaft 41, the drive shaft 40 being configured for positioning the main shaft 41 in different angular positions with respect to the transmission shaft 46 depending on the type of gas to be supplied.
  • the main shaft 41 comprises an end 43 to which there is coupled an outer knob (not depicted) that can be operated by the user, and another end 42 which is coupled with the transmission shaft 46.
  • Said transmission shaft 46 comprises a lower end 48 acting on the transmission element 70, and an upper end 47 which is coupled with the end 42 of the main shaft 41.
  • the lower end 48 of the transmission shaft 46 is arranged in the housing 51 when the drive shaft 40 is not axially pushed, and is coupled to the rotating disk 20 in a coupling hole 24 which is comprised in said rotating disk 20 and has a D shape in this embodiment. Said coupling hole 24 allows the axial movement of the transmission shaft 46 without axially moving the rotating disk 20.
  • the rotating disk 20 is arranged facing the transmission element 70.
  • the body 10 of the gas cock 100 comprises a through hole 14 which is communicated through one of its ends 15 with the housing 51, the transmission shaft 46 of the drive shaft 40 going through the through hole 14, said transmission shaft 46 being tightly fitted with possibility of rotation and axial movement in said through hole 14.
  • the other end of the through hole 14 is communicated with a seat of the body 10, a gasket 80 being arranged on said seat surrounding the transmission shaft 46 and tightly fitted against the seat, assuring the leak-tightness between the two ends of the through hole 14 of the body 10.
  • the contact area 52 on which the rotating disk 20 is supported comprises a flat support surface comprising a channel surrounding the outlet hole 53, a sealing gasket 57 being housed in said channel pressed against the support face of the rotating disk 20 when the rotating disk 20 is supported on the contact area 52. Gas flow towards the gas outlet conduit 12 is thereby regulated when the rotating disk 20 is rotated and when the connection opening 21 of the rotating disk 20 overlaps with the outlet hole 53.
  • the gas cock 100 comprises a cover 60 attached to the body 10 closing, in a leak-tight manner, a chamber 50 formed by the housing 51 of the rotating disk 20 and a second housing 55 arranged in the cover 60.
  • the chamber 50 is leak-tight because a sealing gasket 58 is arranged between the cover 60 and the body 10.
  • the second housing 55 is communicated with the safety valve 30, the transmission element 70 which acts on the safety valve 30 being housed in the second housing 55.
  • Said second housing 55 is separated in a leak-tight manner from the housing 51 by the rotating disk 20, and said second housing 55 is fluidically communicated with the safety valve 30.
  • the transmission element 70 is a rocker arm
  • the safety valve 30 comprises a shutter closing it, such that when the drive shaft 40 is pushed axially, the lower end 48 of the transmission shaft 46 presses the transmission element 70, and this transmission element acts on the shutter, opening the safety valve 30.
  • the incoming gas can therefore go from the inlet conduit 11, through the safety valve 30, and to the second housing 55, the chamber 50 being leak-tight.
  • the gas cock 100 comprises an attachment element 97 which, in this embodiment of the gas cock 100, is a screw.
  • the main shaft 41 is hollow, comprising a through hole 98 open at its upper end 43 and lower end 42.
  • the lower end 42 widens, generating an inner cavity 42c.
  • the transmission shaft 46 comprises at its upper end 47 a widening, forming a head 47a, said head 47a comprising a threaded hole 47b in its upper portion facing the lower end 42 of the main shaft 41.
  • the drive shaft 40 comprises a coupling unit 95 fixed to the lower end 42 of the main shaft 41.
  • the coupling unit 95 comprises an annular central body comprising axially a central through hole 95a.
  • An axial stud 98 that protrudes towards the transmission shaft 46 and a radial stud 99 that projects laterally project from the central body.
  • the lower end 42 of the main shaft 41 comprises on the lower edge a first groove 42a and a second groove 42b which are arranged opposite one another in this embodiment, the radial stud 99 and the axial stud 98 being coupled, respectively, in said grooves 42a and 42b.
  • the coupling unit 95 is therefore part of the main shaft 41, and they are riveted to assure the integral fixing thereof.
  • the main shaft 41 is made of brass, and it can also be made of aluminum, and the coupling unit is made of steel.
  • the main shaft comprises the stud and the radial stud at its lower end, the through hole of the main shaft being of such dimensions that it allows introduction of the attachment element from the opening of the through hole at the upper end of the main shaft.
  • the head of the attachment element 97 is supported on the upper portion of the central body of the coupling unit 95, and the threaded body of said attachment element 97 goes through the through hole 95a, the attachment element 97 being screwed into the hole 47b of the transmission shaft 46.
  • the gas cock 100 comprises a spring 94 which is arranged between a washer 96 and an abutment surface 47c of the transmission shaft 46, which is the lower portion of the head 47a.
  • the washer 96 covers the seat on which the gasket 80 is arranged, being coupled in this embodiment to the transmission shaft 46 going therethrough.
  • the spring 94 allows returning the transmission shaft 46, and along with said transmission shaft 46 the drive shaft 40, when the main shaft 41 and the transmission shaft 46 are coupled, to a standby position when it stops pushing said drive shaft 40, by means of the main shaft 41, for pushing the transmission element 70 and opening the safety valve 30.
  • the transmission shaft 46 comprises in the head 47a a housing 49 which in this embodiment is a partial perimetral gap at the edge of the head 47a.

  • the axial stud 98 is arranged in the housing 49.
  • the gas cock 100 is configured for natural gas by the axial stud 98 being arranged in the stop 49 1 , and configured for liquefied petroleum gas by the axial stud 98 being arranged in the stop 49 2 , so the main shaft 41 is positioned in different angular positions with respect to the transmission shaft 46, and therefore to the rotating disk 20 to which it is coupled.
  • the end of the attachment element 97 is in contact with the hole 47b of the transmission shaft 46, without being fixed, and the axial stud 98 of the coupling unit 95 has a length such that said axial stud 98 is still arranged in the housing 49 of the transmission shaft 46, such that the main shaft 41 and the transmission shaft 46 are not separated from one another.
  • the spring 94 of the gas cock 100 therefore pushes the transmission shaft 46, and the user first rotates the main shaft 41 with the suitable tool until the axial stud 98 abuts with one of the stops 49 1 and 49 2 corresponding with the supply gas, and then acts on the attachment element and fixes the main shaft 41 and the transmission shaft 46 in the defined position with the suitable tool.
  • the drive shaft 40 To finish configuring the gas cock 100 to one of the supply gases, the drive shaft 40 must always be arranged in a reference position D1, such that when the main shaft 41 and the transmission shaft 46 are coupled, and the main shaft 41 angularly moved with respect to the transmission shaft 46, when the drive shaft 40 is brought to the reference position D1, the rotating disk 20 will be angularly moved at an angle equivalent to the angular difference between ⁇ 1 and ⁇ 2 between the two supply gases defined in this embodiment.
  • the radial stud 99 is arranged in the reference position D1.
  • this reference position D1 corresponds with the initial rotation position of the main shaft 41, although in other embodiments it may correspond with the final rotation position, for example.
  • this initial rotation position of the main shaft 41 corresponds with the position with minimum gas flow, the final rotation position corresponding with the position with no gas flow.
  • the gas cock 100 comprises a cap 90 which is fixed to the body 10 and with the main shaft 41 going through same, specifically in this embodiment of the gas cock 100 through the lower end 42 where the main shaft 41 widens forming the inner cavity 42c.
  • This second chamber 91 is arranged opposite the chamber 50 in reference to the body 10 of the gas cock 100, and in the direction of the drive shaft 40, both chambers 50 and 42 being separated by the through hole 14 of the body 10.
  • the cap 90 comprises therein a sliding surface for the radial stud 99, which is pushed against the cap 90 by means of the spring 94, and two stops 92 and 93 of the angular path A of the main shaft 41 between the initial rotation position and the final rotation position, the position of stop 92 corresponding to the reference position D1.
  • the radial stud 99 is positioned in the stop 92.
  • Figure 7 shows a perspective view of an embodiment of the rotating disk 20 with a connection opening 21 comprising ten holes 25 1 -25 10 , the hole of one end 25 10 having larger dimensions, and in terms of their diameter the holes being arranged such that a series of holes of different diameters are interposed within a series of holes increasing in size, in order to obtain a more regular gas flow in the outlet of the gas cock 100.
  • This row of holes has a radial shape, such that to obtain the gas flow rate required in the gas outlet conduit 12, regulation is performed by overlapping a number of consecutive holes 25 1 -25 10 with the outlet hole 53, and the change in gas flow is performed by means of said overlapping holes 25 1 -25 10 leaving and entering the ends of the outlet hole 53 at the same time.
  • Figures 9a to 9b show a sectional front view of the gas cock of Figure 1 , the rotating disk 20 being arranged in gas flow regulation positions for natural gas and liquefied petroleum gas, respectively, when the gas cock 100 is in the OFF position in which it does not supply any gas, such that the connection opening 21 of the rotating disk 20 does not overlap with the outlet hole 53 for any of the two gas supplies.
  • Figures 10a to 10b show a sectional front view of the gas cock of Figure 1 , the rotating disk 20 being arranged in gas flow regulation positions for natural gas and liquefied petroleum gas, respectively, when the gas cock 100 is in the minimum MIN gas flow position, such that holes 25 1 -25 3 overlap with the outlet hole 53 when the gas cock 100 is configured for supplying natural gas, and only the hole 25 1 overlaps with the outlet hole 53 when the gas cock 100 is configured for supplying liquefied petroleum gas.
