Definitions

  • the present patent application relates to an assembly comprising a gas valve, a fan, a gas/air mixer and a burner door.
  • DE 10 2004 007 123 B3 discloses an assembly comprising a gas valve for providing gas, a fan for providing air and a gas/air mixer for mixing the gas with the air thereby providing a gas/air mixture.
  • the gas valve comprises a gas valve housing providing a gas inlet through which the gas valve is connectable to a gas pipe, and further providing a gas outlet through which the gas valve is connectable to the gas/air mixer.
  • the gas/air mixer comprises a gas/air mixer housing providing a gas inlet through which the gas/air mixer is connectable to the gas outlet of the gas valve, providing an air inlet, and providing a gas/air mixture outlet.
  • the gas/air mixer is mounted to a support plate of the fan by a bayonet-connection.
  • WO 2014/019835 A1 discloses a fan with an integrated manifold for a gas burner.
  • the fan comprises a fan housing having a fan housing lower part, a fan housing lid and a protection cover for a fan motor of the fan.
  • the fan housing lid carries the fan motor and serves as fan plate housing part.
  • the manifold is integrated with the fan housing lower part.
  • the fan housing lower part and the fan housing lid define together with the manifold which is integral with fan housing lower part a flow channel for the gas/air mixture.
  • a novel assembly comprising a gas valve, a fan, a gas/air mixer and a burner door is provided.
  • the fan comprises a fan housing and a fan motor carrying a fan impeller
  • the fan housing comprises a fan plate housing part carrying the fan motor and a fan impeller housing part
  • the fan plate housing part and the burner door are commonly provided by one monolithic element.
  • the claimed invention reduces the space occupied by the assembly comprising the gas valve, the fan, the gas/air mixer and the burner door.
  • the fan impeller housing part and the monolithic element which commonly provides the fan plate housing part and the burner door define together a flow channel for the gas air mixture, wherein the fan impeller housing part provides an gas/air mixture inlet of said flow channel through which the fan impeller housing part is connectable to the gas/air mixture outlet of the gas/air mixer, and wherein the burner door provides an gas/air mixture outlet of said flow channel.
  • the fan impeller housing part is positioned between the gas/air mixer and the monolithic element which commonly provides the fan plate housing part and the burner door, wherein the fan motor and fan impeller are positioned on opposite sides of the monolithic element which commonly provides the fan plate housing part and the burner door, and wherein a shaft of the fan impeller is guided from the fan impeller to the fan motor through an opening of the monolithic element which commonly provides the fan plate housing part and the burner door.
  • This further reduces the space occupied by the assembly.
  • the fan impeller housing part comprises grooves for receiving a non-return valve
  • the non-return valve comprises a valve frame made from a relative rigid material and a valve flap made from a relative elastic material, and wherein the non-return valve is inserted into the grooves of the impeller housing part through the valve frame with the valve flap being attached to the valve frame.
  • the invention relates to an assembly comprising a gas valve 10 for providing gas, a fan 11 for providing air, a gas/air mixer 12 for mixing the gas and the air thereby providing the gas/air mixture, and a burner door 13 for connecting the assembly to a gas burner.
  • the gas burner is combusting the gas/air mixture within a burner chamber of the same.
  • the gas valve 10 comprises a gas valve housing 14 providing a gas inlet 15 through which the gas valve 10 is connectable to a gas pipe, and further providing a gas outlet 16 through which the gas valve 10 is connectable to the gas/air mixer 12.
  • the gas valve 10 comprises control elements to control the gas flow though the same.
  • the fan plate housing part 24 which carries the fan motor 22 and the burner door 13 for connecting the assembly to a gas burner are commonly provided by one monolithic element 26. This reduces the space occupied by the assembly.
  • the fan impeller housing part 25 and the monolithic element 26 which commonly provides the fan plate housing part 24 and the burner door 13 define together a flow channel for the gas/air mixture.
  • the fan impeller housing part 25 comprises an gas/air mixture inlet 27 of said flow channel for the gas/air mixture through which the fan impeller housing part 25 is connectable to the gas/air mixture outlet (not visible) of the gas/air mixer 11.
  • the burner door 13 provides a gas/air mixture outlet 28 of said flow channel for the gas/air mixture. This further reduces the space occupied by the assembly.
  • the fan impeller housing part 25 is positioned between the gas/air mixer 12 and the monolithic element 26 which commonly provides the fan plate housing part 24 and the burner door 13.
  • the fan motor 22 of the fan 11 and the fan impeller 23 of the fan 11 are positioned on opposite sides of the monolithic element 26 which commonly provides the fan plate housing part 24 and the burner door 13.
  • a shaft 29 of the fan impeller 23 is guided from the fan impeller 23 to the fan motor 22 through an opening (not visible) of the monolithic element 26 which commonly provides the fan plate housing part 24 and the burner door 13. This further reduces the space occupied by the assembly.
  • the fan impeller housing part 25 and the monolithic element 26 which commonly provides the fan plate housing part 24 and the burner door 13 are connected to each other by a screw connection comprising several screws 30 extending through mounting holes 33 of the fan impeller housing part 25 and extending in mounting holes 34 of the monolithic element 26.
  • Said grooves surrounds the gas/air mixture inlet 27 of the fan impeller housing part 25 and said sealing ring seals the fan impeller housing part 25 against the gas/air mixer housing 17 in the region in which the gas/air mixture flows from the gas/air mixer housing 17 into the gas/air mixture flow channel defined by the fan impeller housing part 25 and by the monolithic element 26 which commonly provides the fan plate housing part 24 and the burner door 13.
  • Figure 6 illustrates an alternative bayonet connection between the fan impeller housing part 25 and the gas/air mixer housing 17 of the gas/air mixer 11.
  • the bayonet connection may also be provided by protrusions 37 at an inner surface of the shown section of the fan impeller housing part 25 acting together with openings 35 and slots 36 at an inner surface of the shown section the gas/air mixer housing 17 of the gas/air mixer 11.
  • the fan impeller housing part 25 and the gas/air mixer housing 17 can also be connected by a screw connection.
  • Figure 6 illustrates also the gas/air mixture outlet 38 of the gas/air mixer housing 17 of the gas/air mixer 11.
  • the fan impeller housing part 25 comprises an integral element 41 providing an additional seat 42 for the gas valve housing 14 of the gas valve 10 when the assembly is shipped from the factory to the customer.
  • Said element 41 providing the additional seat 42 is in the embodiment of Figure 2 formed integral with one of the brackets 32 at the outer surface of the fan impeller housing part 25. This further reduces the space occupied by the assembly especially during shipment.
  • the fan impeller housing part 25 comprises grooves 43 or receiving a non-return valve 44.
  • the non-return valve 44 comprises a valve frame 45 made from a relative rigid material and a valve flap 46 made from a relative elastic material.
  • the valve flap 46 is hinged to a sealing ring 47 made from a relative elastic material.
  • the valve frame 45 comprises a groove 48 for the sealing ring 47.
  • the valve flap 46 is attached to the valve frame 45 though the sealing ring 47 when the sealing ring 47 is positioned in the groove 48 of the valve frame 45.
  • the non-return valve 44 is inserted into the grooves 43 of the impeller housing part 25 through the valve frame 45 with the valve flap 46 being attached to the valve frame 45. This provides an improved integration of the non-return valve 44.
