  • THIS INVENTION relates to an immersion heater. It also relates to accessories for use with the immersion heater. More particularly, it relates to an immersion heater of the kind, which is suitable for heating or boiling water, for use in the preparation of coffee, tea, or other hot beverages, although it is to be understood that the immersion heater of the invention can have other uses.
  • the conventional immersion heaters presently in use comprise a handle and heating element. They are limited in that they are not designed to be fixed to the pontainers or vessels with which they are used. The vessel with which they are used cannot easily and efficiently be filled or emptied without removing the conventional immersion heater. Likewise there is no provision made to protect the immersion heater items, such as food, in the liquid which is heated.
  • an immersion heater for use with a vessel having a rim defining a mouth through which liquid can be poured into or from the vessel
  • the immersion heater comprising: an annular body, which defines an opening, and is adapted to fit on said rim so that, while the body is in position on the rim, liquid can be poured into or from the vessel through said opening; and a heating element, which is mounted on the body and is arranged to extend into the vessel when the body is in position on the rim, for heating liquid contained in the vessel.
  • That end of the body which will, in use, be the lower end may have a first coupling formation for engaging with a second, complementary coupling formation on said rim.
  • the other (i.e. upper) end of the body may have a third coupling formation, for receiving a closure having a complementary, fourth coupling formation.
  • the third coupling formation may correspond to the second coupling formation, so that the closure may engage with either the second coupling formation (when the immersion heater has been removed from the rim) or with the third coupling formation (when the immersion heater is in position on the rim).
  • the coupling formations may be male/female screw threads. Although mention is made of an annular opening and an annular body, it is not to be construed that the said opening cannot be of some other shape.

  • reference numeral 10.1 generally indicates an immersion heater, which comprises an annular body 12 defining an opening 14, and an electric heating element 16 mounted on the annular body.
  • the annular body 12 comprises an upright cylindrical part 18 and an annular flange 20 at the lower end of the cylindrical part.
  • the downwardly facing surface of the flange 20 has a plurality of concentric ridges 22 protruding downwardly therefrom, each ridge having a V-shaped profile in vertical section.
  • the ridges 22 serve to centralize the immersion heater on the rim of a vessel, the different ridges making the immersion heater suitable for vessels of different sizes.
  • the immersion heater will be used with only one of them at a time.
  • the flange 20 seats on the rim of the vessel.
  • an external screw thread 24 At the upper end of the cylindrical part 18 there is an external screw thread 24. This enables a cap (not shown) having a complementary internal screw thread to be screwed onto the, annular body if desired, thereby closing the opening 14.
  • the upper edge of the cylindrical part 18 is shaped to form it with a curved pouring lip 26, which extends around the entire periphery of the upper edge.
  • the heating element 16 has a head 28 via which it is mounted on the annular body 12.
  • a conventional immersion heater it further has a pair of limbs 30 (only one of which is visible in the drawing) which extend from the head 28 downwardly, and a coiled part 32 between the lower ends of the limbs.
  • the head 28 may, on the outside of the annular body, have a socket which can receive a conventional electric plug-in connector of the type used for kettles, for connecting the immersion heater to a mains power supply.
  • the plug-in connector will be connected to a lead which has a mains plug at the other end thereof, for plugging the lead into a wall socket.
  • the immersion heater may be provided with an integral power lead which emerges from the head 28 and has a mains plug at the free end thereof.
  • the annular body 12 may be buoyant, the buoyancy being sufficient to keep the entire immersion heater afloat when placed in water.
  • reference numeral 10.2 generally indicates an immersion heater, which differs from the immersion heater 10.1 in that the cylindrical part 18 and the flange 20 are so constructed that they can be separated from one another, e.g. by having complementary screw threads at 34.
  • the flange 20 in this embodiment is provided with an annular skirt 36, which is provided internally with a screw thread 38 and externally with a screw thread 40. This will enable the annular body 12 to be coupled to a vessel, which has a rim with a complementary external or internal screw thread, as the case may be. It is to be understood that the skirt 36 may have only one of the screw threads 38, 40.
  • the upper end of the cylindrical part 18 is provided with a hinged lid 42 for closing the opening 14. Also, instead of the upper edge of the cylindrical part 18 having a curved pouring lip, which extends around the entire periphery of the upper edge, it is provided with a pouring spout 44 on that side thereof which is opposite the hinge of the lid 42.
  • reference numeral 10.3 generally indicates an immersion heater, which fits on a vessel V, the immersion heater 10.3 differing from the immersion heaters 10.1 and 10.2 in that the annular flange 20 has been done away with. Instead, the lower end 46 of the cylindrical part 18 tapers down somewhat, to enable it to fit snugly inside the rim of the vessel V.
  • the opening 14 is, in this embodiment, closed by means of a removable stopper 48.
  • an immersion heater 10.4 which differs from the immersion heater 10.3 in that, instead of the cylindrical part 18 having a tapered lower end, it has a lower end 50 with a stepped configuration as illustrated. Furthermore, in this embodiment, the opening 14 is closed by means of a screw-top 52, which has a hollow interior.
  • the hollow interior of the screw-top 52 may be evacuated, or contain a material which has good heat-insulating properties.
  • the screw-top 52 has a skirt with an internal screw thread, whereby it can be screwed onto an external screw thread 54 at the upper end of the cylindrical part 18.
  • an immersion heater 10.5 which is adapted to be used with a vessel having a screw-threaded rim, and a screw- top (not shown), which can be screwed onto the rim, thereby to close the vessel.
  • the annular body 12 is adapted to be interposed between the rim and the screw-top.
  • the cylindrical part 18 is provided, at the lower end thereof, with an internal screw thread 56 and, at the upper end thereof, with an external screw thread 58, the screw threads 56 and 58 being complementary.
  • the annular body 12 of the immersion heater 10.5 is further provided with a socket 60 for receiving a plug-in connector 62, the socket 60 sloping downwardly and outwardly. This downwardly and outwardly sloping configuration of the socket enables the centre of gravity of the immersion heater 10.5 to be as low as possible, thereby reducing the risk of a vessel having the immersion heater coupled thereto toppling over.
  • the immersion heater 10.6 illustrated in Figure 6 is similar to the immersion heater 10.5, except in that the cylindrical part 18 is provided, at the lower end thereof, with an external screw thread 64 and, at the upper end thereof, with a complementary internal screw thread 66.
  • an immersion heater 10.7 which is similar to the immersion heater 10.5, but suitable for use with a larger vessel V.
  • the immersion heater 10.7 differs from the immersion heater 10.5 in that the cylindrical part 18 is provided with a hook formation 68 on one side thereof.
  • the hook formation 68 enables the immersion heater to be engaged with the rim of the vessel V in such a manner that the immersion heater is supported in a cantilever fashion by the vessel, without there being direct contact between the heating element 16 and the inside surface of the vessel.
  • an immersion heater 10.8 which is similar to the immersion heater 10.5 but is in addition provided with a level indicator 70.
  • the level indicator 70 comprises a buoyant, bulbous part 72 and a stem 74 which extends upwardly from the bulbous part, the stem being slidable in guides 76 provided for this purpose on the inside of the cylindrical part 18.
  • the immersion heater 10.5 is shown to be fitted with an adaptor ring 78.
  • the upper part of the adapter ring is provided with formations suitable for having the lower end of the cylindrical part 18 coupled thereto, whereas the underside of the adaptor ring has different formations which adapt it to be coupled to or used with different kinds of vessels.
  • the formations may be screw threads, formations that engage the rim of the vessel frictionally, and so on.
  • FIG 10 illustrates the use of the immersion heater 10.5 with a vacuum flask F.
  • the vacuum flask F is of conventional construction, comprising a housing 80 and an inner container 82 inside the housing, the inner container being of conventional double-walled construction with the walls thereof being silvered and the space between the walls being evacuated. As is well known, this minimises the loss of heat through the walls of the inner container.
  • the screw-top 52 is the vacuum flask's own closure and would normally, when the immersion heater 10.5 is not used, be screwed onto the neck of the vacuum flask. However, when the immersion heater is used, it is interposed between the neck of the vacuum flask and the screw-top.
  • Figure 11 illustrates how the immersion heater 10. 5 can be supported in an upside down condition on a flat horizontal surface without toppling over. This is achieved by virtue of the fact that the upper edge of the cylindrical part 18 lies in a horizontal plane and that the centre of gravity of the immersion heater is such that, when it is placed in the position illustrated in Figure 11, it will remain standing in that position without toppling over.
  • the immersion heater can conveniently be placed in this position when not in use, allowing the heating element 16 to cool down without causing damage.
  • Figure 12 illustrates how the immersion heater 10.5 is used with a vessel which has a main section VM and a secondary section VS, there being a common wall W which separates the main and secondary sections from one another.
  • the secondary section VS has a rim which is adapted to have the lower end of the cylindrical part 18 coupled thereto, so that the immersion heater can, for example, be used to heat water contained in the secondary section.
  • the wall W is of a material which has good heat-conducting properties, the contents of the main section of the vessel can be heated indirectly, by heat which is conducted through the wall W.
  • an immersion heater 10.13 which is similar to the immersion heater 10.1 of Figure 1. It differs from the immersion heater 10.1 in that it is provided with a cage-like structure 84 around the heating element 16. This will prevent solid objects in the vessel V1 , V2 (e.g. eggs that are being boiled) from coming into direct contact with the heating element 16.
  • an immersion heater 10.14 which differs from the immersion heater 10.13 in that, instead of the cage-like structure 84, there is provided a wall 86 of a heat conducting material capable of containing water or other liquid. With this construction it is possible to heat a first liquid 88 contained by the wall 86, and, indirectly, a second liquid 90 that is contained in the vessel V, the wall 86 being immersed in the liquid 90.
  • Figure 15 illustrates the use of the immersion heater 10.1 of Figure 1 with a pouch-like container 92 which is immersed in the liquid 90 contained in the vessel V.
  • the pouch-like container 92 has its rim supported by the upper end of the cylindrical part 18.
  • the pouch-like container 92 may be of a flexible but impermeable material, as illustrated in the drawing, in which event it is able to contain a liquid 94 which is at a different level than the liquid 90 in the vessel V.
  • the pouch-like container 92 may be of a permeable material, so that liquid can flow through the wall of the pouch- like container and the levels of liquid inside and outside the pouch-like container will equalise.
