Definitions

  • the invention relates to an assembly of a heater and a fuel holder placeable on the heater, the fuel holder being provided with a metering part with a fuel outflow opening, the metering part being provided with a closing means which can be brought in a first or a second position, respectively, for closing off or not closing off, respectively, the outflow opening, the metering part being further provided with spring means arranged for applying a spring force to the closing means, such that under the influence of this spring force the closing means is brought into the first position, the heater being provided with a fuel filling opening provided with means for bringing the closing means of the fuel holder in the second position, against the spring force of the spring means, when the fuel holder with the metering part is placed in a filling position in the filling opening of the heater.
  • the metering part of the fuel holder is coupled by way of the outflow opening to the filling opening of the heater.
  • the fuel holder is, as a rule, in an upside-down position, at least with the metering part and the outflow opening turned downwards.
  • the filling opening of the heater is arranged for bringing the closing means of the fuel holder into the second position when the holder has been placed on the heater in the filling position so that fuel present in the holder can flow into the heater.
  • the heater is provided at the filling opening with an upwardly projecting pin which pushes the closing means of the holder to the second position against the spring force of the spring means. After the fuel holder is positioned on the heater, the pin applies an upwardly directed normal force to the closing means, which normal force is a reaction force of the gravitational force applied by the mass of the fuel holder to the pin.
  • the fuel outflow opening of the metering part of the fuel holder is relatively small, as during burning of the heater, as a rule, a relatively small fuel flow flows to the heater via the opening. Furthermore, the small size of the fuel outflow opening is desired to prevent fuel from being spilled during placement of the fuel holder onto the heater or taking the fuel holder from the heater. Moreover, as a result, refilling the fuel holder by a user is considerably hampered or even made impossible.
  • An advantage of the known assembly is that at any location, the heater can be provided with fuel by the fuel holder. Furthermore, the heater and the fuel holder detachable therefrom can be transported and stored safely and separate from each other, while the outflow opening of the fuel holder is safely closed off by the closing means. Furthermore, coupling the fuel holder to the heater proceeds in a relatively simple manner by simply placing the holder onto the heater in the desired filling position. The holder can then be retained in position, by means of, for instance, retaining means such as clamping and/or strapping means or the like, connected to the heater, and/or wall parts of the heater extending along the holder.
  • the fuel holder comprises a relatively large metal fuel can, while the metering part comprises a detachable metal cap.
  • the outflow opening and the spring means of the fuel holder are provided in this cap.
  • the cap can be taken from the fuel holder so that relatively large fuel holder filling opening is cleared. Then, the holder can be refilled via the holder filling opening.
  • a drawback of the known assembly is that refilling the fuel can is relatively cumbersome and requires great accuracy. Fuel may then be spilled. When fuel is spilled, for instance clothes of bystanders may be ruined.
  • An important drawback of the known assembly is that the fuel can is relatively large and heavy, which will complicate transport, handling and storage of this fuel holder. By contrast, small fuel cans have the drawback that they have a limited content.
  • the present invention contemplates solving problems of the known assembly while maintaining its advantages.
  • the invention contemplates an assembly of a heater and a fuel holder, while the assembly can be used in a relatively safe manner.
  • the assembly is characterized to this end in that the fuel holder metering part is undetachably connected to a wall of the fuel holder.
  • the fuel holder is suitable to be used once, which is relatively safe compared with reuse of the holder.
  • the metering part cannot easily be removed from the fuel holder, at least not without damaging the holder and rendering it unfit for use, in that the metering part is undetachably connected to the holder, for instance in that it forms an integral part of the wall of the holder. Accordingly, after use, when fuel stored in the holder has been used up by the heater, the fuel holder is to be replaced by a new, filled fuel holder to provide the heater with fresh fuel. By each time using a new fuel holder, the cumbersome step of refilling the fuel holder need not be carried out. Each used-up, empty fuel holder can, for instance, be recycled.
  • the holder can be of relatively light and yet sufficiently strong design. Manufacturing the holder entirely from plastic, the spring means included, is particularly advantageous because, as a result, the holder is more easily recyclable than a holder composed from various materials. Further, a plastic holder can be manufactured in large quantities relatively inexpensively, which is advantageous when the holder is used as a disposable container. By designing each holder to be relatively light, the holder can contain more mass in fuel before reaching a particular total weight relative to a comparatively heavy holder, which is advantageous from the point of view of transport.
  • HDPE high density polyethylene
  • This plastic has a low density, so that weight can be economized on.
  • HDPE is somewhat translucent, so that the fuel level in the holder can be observed from the outside when the holder wall is manufactured from HDPE.
  • HDPE in itself is relatively fuel impermeable, which is requisite for the durability and safety of the fuel holder.
  • the invention further provides a fuel holder characterized by the subject matter of claim 17.
  • This holder is very safe in use as the fuel holder metering part is undetachably connected to a wall of the fuel holder. Undesired refilling of the holder is thus prevented. For that reason, the holder is particularly suitable for single use, which offers the above-mentioned advantages.
  • Fig. 1 shows an assembly of a heater 1 with a fuel holder 110 known from the state of the art.
  • the heater 1 is provided with a burner head 30 and a wick 4 for soaking up fuel B from a lower container 5, transporting it to an evaporation surface 6 and evaporating it there for the purpose of burning the fuel.
  • the heater 1 comprises an air lock 7 for feeding air to the evaporated fuel B for the purpose of burning the fuel B in the burner head 30.
  • the air flow is indicated by arrows in Fig. 1.
  • the known fuel holder 110 comprises a fuel reservoir enclosed by a wall 115. As shown in Fig. 1, the holder 110 is placed, during use, by a metering part 114 on a filling opening 2 of the lower container 5 of the heater 1 for continuously refilling this lower container 5 with fuel B to a filling level represented by a dotted line 8. In the filling opening 2, a filter 9 is arranged for filtering the fuel flowing via this opening 2 to the lower container 5. By means of a threaded connection, the metering part 114 is detachably connected to the holder 110.
  • the metering part 114 of the fuel holder is provided with a fuel outflow valve comprising an assembly of a plug 112, a metal spring 113 and a fuel outflow opening 111.
  • the plug 112 With the plug 112 in a first position (not shown), the outflow opening 111 is closed off by that plug 112.
  • a second position of the plug 112 is represented with the plug 112 not closing off the outflow opening 111.
  • the spring 113 is arranged for applying a spring force to the plug 112 such, that under the influence of that spring force, the plug 112 can be brought from the second position to the first position.
  • the filter of the fuel filling opening 2 of the heater 1 is provided with an upwardly projecting pin 3 for bringing and retaining the plug 112 of the fuel holder 110 in the second position, against the spring force of the spring means 113 when the fuel holder is placed on the heater in the filling position shown.
  • the holder 110 known from the state of the art comprises a metering part 114 which can be unscrewed, entailing the drawbacks mentioned in the introduction.
  • Figs. 3 - 4 show a part of a fuel holder 10 according to the invention.
  • This fuel holder 10 is provided with a convex metering part 14 integrally connected to the fuel holder wall 15.
  • the metering part 14 is provided with a circular outflow opening 11.
  • a closing means 12 is arranged, which can be brought in a first or second position, respectively, for closing off or not closing off, respectively, the outflow opening 11.
  • the first position of the closing means is represented.
  • the closing means 12 is connected to an inside 23 of the metering part 14.
  • the spring means 13 are arranged for applying a spring force to the closing means 12 such that under the influence of this spring force, the closing means 12 is brought into the first position.
  • the closing means 12 comprises a frustoconical body 16 which, in the first position of the closing means 12, is contiguous to an inside of the outflow opening 11 for closing off that opening 11.
  • the concave outer side 17 of the closing means 12 comprises a segment of a spherical surface, such that the closing means 12 engages the pin 3 in a self-centering manner as the holder 10 is being placed in the filling position onto the heater 1 in the above-described manner.
  • a cylindrical guiding element 20 At right angles to an inside 19, remote from the outer side 17, of the frustoconical body 16 extends a cylindrical guiding element 20. At an outside, this guiding element 20 is provided with four guiding ribs 21 extending in longitudinal direction of this element.
  • the spring means 13 comprise a spiral spring 13 extending around the guiding element 20. By one end, the spiral spring 13 is integrally connected to the inner side 19 of the frustoconical body 16. By means of three cross connections 24, the other end of the spiral spring 13 is connected to a fastening ring 22. This fastening ring 24 is connected to the inner wall 23 of the metering part 14, for instance by a snap and/or glue connection.
  • the spring means 13 comprise a plastic spiral spring.
  • the closing means 12 is designed substantially from plastic.
  • the closing means can, for instance, be an integral part of the spring means.
  • the fuel holder 10 can be manufactured entirely from plastic.
  • the wall 15 of the fuel holder is manufactured from High Density Polyethylene (HDPE).
  • the spring means 13 of the closing means 12 preferably apply a spring force to the closing means such that the fuel filling opening 2 of the heater 1 retains the closing means 12 of the fuel holder 10 in the second position, at least under the influence of the weight of the fuel holder 10, when the fuel holder 10 is in the filling position.
  • the spring means do not apply so large a spring force that the closing means is already moved back by the spring means to the closed, first position while the holder 10 still contains a certain amount of fuel.
  • the spring means 12 do need to apply a sufficiently large spring force, such that the closing means is moved completely to the first position when the fuel holder 10 is in a position of rest, moved away from the heater 1.
  • the heater 1 and fuel holder 10 according to the invention are relatively safe in use as the holder 10 is only suitable for single use.
  • the fuel holder can be manufactured from various materials.
  • the holder is manufactured completely from disposable material.
  • the holder 10 does not comprise metal parts, in particular for designing the holder to be relatively light.
  • the outflow opening 12 can have different sizes.
  • the diameter of the outflow opening is not more than approximately 1 cm.
  • the outflow opening 12 can be shaped in various manners, such as circular, angular, or comprise a combination of these and other shapes.
  • the outflow opening 12 can be designed in different manners, for instance in that the opening 12 comprises a bore, is provided with a porous mass or a porous dispensing body or in that the outflow opening 11 is designed in a different manner.
  • the holder can be placed on the heater in various orientations, for instance horizontally, vertically and/or at an inclination, depending on the position of the metering part and the outflow opening of the holder.
  • the holder can be placed on the heater in different positions, depending on the position of the filling opening of the heater.
  • the spring means 13 can for instance be arranged for allowing the closing means 12 to be brought from the first to the second position when the means 3 of the fuel filling opening 2 apply a force to the closing means which is less than approximately 3 N, in particular less than approximately 2 N.
  • a fuel holder of relatively light design can still be opened by the means 3, such as the pin 3, for the purpose of fuel supply to the heater 1, in particular in the event that the holder 1 is only filled with fuel to a limited extent.
  • the outflow opening of the holder is prevented from being closed off prematurely by those spring means, so that the holder can entirely empty into the heater 1.
  • the mass of the holder is less than approximately 0.3 kg, in particular less than approximately 0.2 kg, so that the holder can be made with relatively little material.
