Definitions

  • the invention relates to a temperature-controlled fuel gas flow valve for a catalytic heating device.
  • the fuel delivery device is a nozzle which is arranged between the fuel tank and the combustion chamber and through which a flow of gaseous fuel is passed into the combustion chamber.
  • a flow of gaseous fuel is passed into the combustion chamber.
  • a catalytic heater is also known (US-A-2 997 869) in which methanol vapor and air are passed onto a catalyst, the fuel gas flowing through a tubular body, at one end of which a rod is arranged coaxially with the tubular body is provided with a catalyst so that the rod-shaped body heats up when the catalytic combustion has started.
  • a hair waving device is known (EP-A-0 021 224 and 0 030 257), in which a valve device is arranged in the device housing between the cylindrical rod body and the guide handle, which prevents the fuel gas from flowing out from the fuel gas tank accommodated in the handle part to the rod body arranged catalyst regulates.
  • the regulation takes place depending on a bimetallic element and also on an actuator that can be operated by hand.
  • This known hair curler in the manner of a curling iron, has the disadvantage that the accuracy of the control essentially depends on the quality of the material used for the handle part, since on the one hand the associated valve device is arranged in the handle part and on the other hand the bimetal element is connected to the cylindrical rod body is.
  • the grip part and the rod body shrink or elongate under the influence of temperature and / or moisture, with the result that the temperature is not exactly maintained, which can lead to hair damage.
  • the present invention has for its object to provide a valve device for a heating device which allows control of the fuel gas flow within narrow limits and in which the properties of the inexpensive materials used have no influence on the control behavior.
  • the valve device should be designed so that it can be installed as an independent unit or assembly both in hair care devices and in other devices for personal needs or for the household, such as pocket stoves, irons or hot plates.
  • a regulator element arranged in a regulator frame, on which a bimetal temperature measuring element acts, which is articulated directly on the displaceable valve member of the valve device, which regulates the fuel supply from the fuel tank to the combustion chamber, both of which the valve member containing and also the holder for the bimetal temperature measuring element and the bearing for the regulator element having regulator frame is integrally formed.
  • the invention allows a wide variety of design options. One of these is shown in more detail in the accompanying drawings using the example of a catalytic heating device for a hair curler or a curling iron.
  • the curling iron consists of the tube 1, the handle part 2 connected to the tube 1 which is filled with fuel gas 3, the handle part 2 to be closed at the end of the plug 4 with filling valve 5, the tube 1 to be closed at the front socket 6, which the bushing 6, which is denoted overall by Z, the burner held by spring windings 7, 8 in the tube 1, denoted overall by B, the combustion chamber denoted by V, the flange 9 arranged between tube 1 and handle part 2, on which the hair clip 10 is tiltably mounted with the control button 11 on the bolt 12 and finally the valve member 13 with the control device consisting of the parts 14, 15, 16, 17, 35, 39, 55 and 40 and designated overall by R.
  • the ignition device Z consists of the rotating piece 18 moved by the actuating button 31 with ramp 19, the holding frame 20, the tube 21 with spring and flint 23, the friction wheel 26 with spur toothing mounted on the pin 25 in the holding frame 20, a ratchet lever 28 with tooth and the Longitudinally displaceable plunger 29 with a return spring 30 mounted in the holding frame 20.
  • the control device R consists of the valve member 13, which is longitudinally displaceable relative to the valve seat 33, the regulator member or regulator lever 16 which is tiltably mounted on the bolt 34, the shift lever 55, the regulator spring 17, the regulating rod 15 with regulator tube 14, the damping spring 39 and the regulating frame 40 with clamping bush 41.
  • the burner B consists of the burner tube 42, the two spring coils with a large diameter 7, 8, the catalytic converter 43, which is held between an inner spring 44 and an outer spring 45, and the front, conically wound part 46 of the inner spring 44.
  • the flange 9 serves, on the one hand, to hold the tube 1 and, on the other hand, to hold the control device R.
  • the handle part 2 holds the hair clamping device 10, 11, 12, the flange 9 itself being firmly arranged on the handle part 2.
  • L is an air duct through which fresh air can flow into the chamber V.
  • the ring 31 is now rotated to ignite the fuel gas. During its rotation, this ring 31 takes the rotary piece 18 with it or sets this part 18 into a rotational movement.
  • the plunger 29 abutting the run-up ramp 19 of the rotary piece 18 is set into an axial movement, since one end thereof is constantly in motion due to the force of the return spring 30 the ramp 19 follows.
  • the plunger 29 is held and guided in the region of the friction wheel 26 and engages with its front end through an opening in the bottom of the holding frame 20.
  • the tube 21 containing the flint 23 is guided by the bent tab of the frame 20 and is towards the front in one Bore of the holding frame 20 stored. Due to the axial movement of the plunger 29, the pawl lever 28, which is rotatably mounted on the pin 25, is pivoted from the bent end of the plunger 29.
  • the tooth of the ratchet lever 28 engages in the ratchet spur toothing of the friction wheel 26 and rotates this a little on the bolt 25.
  • the flint 23 in the tube 21 under the tension of a spring now rubs against the rotating friction wheel 26, so that sparks are struck which ignite the gas mixture in the combustion chamber V between the igniter Z and the burner B.
  • the valve member 13 is moved by the regulator lever 16 relative to the valve seat 33, for which purpose the lever 16 is tiltably mounted on the bolt 34.
  • the control lever 16 is acted upon by the damping spring 39.
  • the regulator spring 17 rests on the shift lever 55, which is rotatably mounted on the regulator frame 40 on the bolt 34.
  • the shift lever 55 is pivoted because the free end of the shift lever 55 fits into a slot in the actuator 35.
  • the regulator lever 16 is also acted upon by a bimetallic device, which consists of a regulator tube 14 with a regulator rod 15 movable therein, the tube 14 and the rod 15 being firmly connected to one another at their front ends at F while the handle-side end of the tube 14 is fastened to the regulator frame 40 by means of a clamping bush 41 and the handle-side end of the regulator rod 15 acts with the head piece 56 on the regulator lever 16.
  • a bimetallic device which consists of a regulator tube 14 with a regulator rod 15 movable therein, the tube 14 and the rod 15 being firmly connected to one another at their front ends at F while the handle-side end of the tube 14 is fastened to the regulator frame 40 by means of a clamping bush 41 and the handle-side end of the regulator rod 15 acts with the head piece 56 on the regulator lever 16.
  • valve 13, 33 When the curling iron is heated, the valve 13, 33 is closed, but is opened when it is cooling. The fuel gas flow flowing between the valve seat 33 and the sealing rubber 59 in the max.
  • the valve opening position is limited by a small, precise bore in the part 40 or in the nozzle 53, so that in any case only a limited amount of fuel gas can escape.
  • the difference in length results in the control path or the path by which one end of the regulator lever 16 is moved by the regulator rod 15.
  • the movement of the valve member 13 relative to the stationary valve seat 33 can be influenced by the position of the actuator 35 in addition to the regulator rod 15. If the actuator 35 is moved to the ON position (arrow direction in FIG. 4), the slot in the actuator 35 moves forward and the shift lever 55 is also pivoted forward (arrow direction in FIG. 3). The regulator lever follows this forward movement and the damping spring 39 is relieved. If the actuator 35 is moved to the OFF position, the spring 17 is relaxed so far and the damping spring 39 is tensioned so far that the valve 13, 33 is closed gas-tight.
  • the control device R shown in FIG. 5, which includes both the bimetal element 14, 15, 56 and the levers 16, 55 with the control spring 17 and the valve device 33, 51, 52, 53, 54 with the control frame 40 comprises, is formed as a single solid assembly and inserted into the curling iron in the manner of a measuring device.
  • this design enables separate assembly, adjustment and testing of the assembly and, on the other hand, tolerances, which mainly occur when the temperature of the housing parts changes, do not affect the regulation of the gas flow.
  • the regulator frame 40 is firmly screwed to the plastic handle part 2, which contains the gas storage space 22.
  • the handle part 2 also contains foam disks 24, the wick 27 and a filter stone 31 through which the fuel gas can flow into the bore 54 (FIG. 3).
  • the game S between the head piece 56 and the regulator lever 16 remains unaffected; in fact, only the overall length of the device is affected.
  • the tube 1 and the handle part 2 are connected to one another via the flange 9, which on the one hand is screwed to the end face 57 of the handle part 2 or its shell-shaped end 32 and on the other hand is wedged to the tube 1.
  • 58, 59, 60 denote the blind holes in the handle part 2, into which the screws (not shown in more detail) are screwed, with which the regulator frame 40 is fastened to the end face of the handle part 2.
