Definitions

  • the invention relates to a fan, in particular for a gas burner, for premixing of air and gas, which has a housing, and with a control valve for regulating the amount of gas, which comprises a valve seat, wherein the valve seat of the control valve is formed from a part of the housing.
  • gas combi regulators are commonly used which provide both the prescribed safety valves for shutting off the gas path upon termination a heat demand or flame failure of the gas burner as well as the control valve needed to control the amount of gas.
  • the gas combi regulators are often arranged upstream of the blower as an extra assembly, with the gas combi regulator providing a connection to the blower which mixes the sucked air with the supplied gas and supplies it to the gas burner.
  • a mixing device for fan-assisted gas burner wherein the fan and the gas-combi controller are housed in a common housing.
  • the advantage is achieved that the mixing of the amount of gas required for combustion takes place directly on the impeller.
  • a disadvantage of this design is that at least the gas-conducting region of the common housing must be gas-tight in accordance with the EN161 standard.
  • the casings of gas blowers are made of die cast.
  • a production of a gas-tight die-cast housing is possible only with additional costly effort.
  • a seal should additionally be provided for the housing, that certainly no gas can escape.
  • blower and gas combination controller in a housing leads to complex manufacturing and test procedures.
  • solution disclosed by the prior art has significant disadvantages, since in case of failure of the fan, the gas combination regulator must also be replaced with. Accordingly, if the gas-combi regulator fails, the fan must also be replaced. This also leads to high costs in both cases.
  • a mixing device for generating a mixture of gas and combustion air for a burner is known.
  • Such a mixing device is further from the DE 10 2004 007 123 B3 disclosed.
  • gas is introduced into a mixing chamber through which the air flow of an externally arranged blower flows.
  • the mixing and mixing of the gas takes place either through an annular gap, or through a Venturi nozzle.
  • the indicated shown mixing devices are provided as additional components in addition to the gas burner and the blower and ensures a good mixing in the desired gas / air ratio.
  • a disadvantage of the shown mixing devices is that for the mixing of air and gas, an additional component must be provided by means of the gas and combustion air to mix in the right proportion, this is on the one hand a large amount of space needed, on the other hand by appropriate additional components such a mixing chamber generates additional costs. Also, at a large distance or a large volume up to the gas burner, a long dead time arise. Dead time in this case means the time until after a Cityae the plant the gas heater enough gas is supplied from the gas line.
  • a blower for combustion air is disclosed, which is designed to be arranged at the air inlet sensor means for determining the air mass flow, which is operatively connected to an electronic control unit and to these signals for processing the ratio of combustion medium / combustion air as a function of the desired Heating power sends.
  • the WO 2008/165030 A2 discloses a gas valve with control and safety valve wherein the valve seat of the safety valve is formed on the gas valve housing.
  • the invention is therefore based on the object to provide a fan with a short dead time, which has a small size and is inexpensive to manufacture.
  • the object is achieved by a blower with the features of claim 1.
  • the erfiridungssiee blower has a housing with a gas supply and a control valve for controlling the amount of gas.
  • the control valve comprises a valve seat, which is formed from a part of the housing. This advantageously ensures that the dead time is very short until the desired amount of gas is fed in and the overall height of the overall construction is significantly reduced.
  • the control valve itself does not have to ensure gas tightness. A fuse against gas leakage can be ensured only by one or more safety devices outside the housing or on the outside of the housing of the blower.
  • valve seat may also be formed in the interior of the housing or on the outer surface of the housing.
  • gas safety valves that meet the above-mentioned standards as a safety device against gas leakage.
  • one or more of these valves may be provided.
  • control valve may have a valve seat and a valve body.
  • a valve body a valve cone can be used, which cooperates with the corresponding valve seat.
  • the valve seat may in this case be designed, for example, as a funnel-shaped depression with a centrally arranged passage opening.
  • the housing is advantageously produced as a die-cast part, wherein the formation of the valve seat on the housing in the casting process, preferably without machining, is produced. Since there is no requirement for gas tightness on the valve seat, die casting quality is sufficient for the surface. Additional post-processing steps can thus be omitted.
  • control valve has a control device, by means of which the valve body is movable relative to the valve seat.
  • this offers a stepper motor for the control device.
  • valve seat As a favorable embodiment can be provided to form an inflow between the control device and the valve seat, which may have a gas outlet to the Radialgebläserad out.
  • the valve body In the inflow space, the valve body can move axially and thus determine the degree of opening of the control valve. Due to the advantageous arrangement of the control valve with valve seat directly to the housing only very short flow paths of the gas are traversed and via the inflow space, the gas can be introduced directly to the impeller for mixing with the air.
  • the opening position of the control valve is preset in a ready position of the blower for a subsequent operating phase.
  • an optimization of the ignition behavior for the next start-up of the gas burner is particularly favorable since it can thus be ensured that the commissioning of the gas burner following the standby position takes place under optimum ignition conditions.
  • this can be of particular importance, since their ignition range is much smaller than that of atmospheric burners.
  • control device of the control valve it is also possible for the control device of the control valve to be arranged on the outside of the housing in a split tube or in an additional protective housing fastened to the outside of the housing and sealed against gas leakage.
  • the protective housing can either be formed as the housing of a die-cast or even a casting or plastic.
  • control device can be controlled electronically via a BUS. It is particularly advantageous that the BUS gas burner for data transmission for the fan and the stepper motor is used. It is also advantageous that the control of the fan and a control or regulation of the control valve via a single circuit board is executable.
  • the microcomputer receives the commands for the control device (stepper motor) via the BUS, whereby the electronics are controlled.
  • control device can be fixed to the housing without additional fastening means. It is favorable that a simple installation without additional fasteners such as screws favorable that a simple assembly without additional fasteners such as screws or the like can be performed.
  • the gas supply can be arranged directly on the gas safety valve or the gas safety valves.

  • the valve body 5 is designed as a valve cone and the valve seat 4 with a shape complementary to the valve cone 5 in order to make a very fine dosage of the amount of gas and especially to be able to adjust very small amounts of gas.
  • the control device 6 is preferably designed as a stepping motor and received between the covers of the housing 2 in a corresponding receiving space. The storage takes place here by recesses in the Dekkeln of the housing 2.

  • the passage 16 may be sealed.
  • the gas outlet 8 is formed as an annular gap.
  • control valve 3 Due to the fact that the control valve 3 according to the invention does not have to perform a safety function against gas leakage, it can already be set at the end of the operation of the gas burner in an optimal position for the next commissioning.
  • the optimal position depends in particular on the Ignition behavior of the gas burner.
  • the safety function against gas leakage is ensured exclusively by the direction indicated in the gas supply 9 safety device 14 against gas leakage.
