Description
OIL BURNER APPARATUS
This invention relates to oil burner apparatus which may be used, for example, in cookers or boilers.
Cookers and boilers are well known.
Cookers are usually installed in kitchens of homes
i ,, and they have a hot plate to cook on, an oven to bake in, and a boiler section for providing hot water and central heating. Boilers can be installed in any desired position in a home, and they usually just provide hot water and central heating. The known cookers and boilers may be fired by solid fuel or by oil.
The known oil fired cookers and boilers often contain oil burner apparatus which is bulky and/or expensive to manufacture.
It is an aim of the present invention to provide oil burner apparatus which is both compact and economical to manufacture.
Accordingly, this invention provides oil burner apparatus comprising a pump motor, a fan, a burner head, and conduit means forming an air flow path between the fan and the burner head, the burner head being mounted substantially over the fan so that the conduit means only has to extend in a vertical direction to form the air flow path between the fan and the burner head.
The oil burner apparatus of the present invention can be produced to be smaller and more compact than known oil burner apparatus. Furthermore, the oil burner apparatus of the present invention can be produced more simply and therefore more economiCally than known oil burner apparatus.
The oil burner apparatus may be a pressure jet oil burner apparatus.
The oil burner apparatus of the present invention may be used in cookers or boilers as indicated.
above. The cookers or boilers will usually be free standing.
The oil burner apparatus of the present invention can be used as a conversion kit for converting cookers or boilers which normally operate on solid fuel into cookers or boilers which operate on oil. The compact size of the oil burner apparatus makes it easy to use in kit form and easy to install in the cookers or boilers. Furthermore, the oil burner apparatus enables the cookers or boilers to be converted back into cookers or boilers operating on solid fuel if this should ever be desired. Thus, for example, at the present moment, the price of oil is advantageous when compared with the price of solid fuel such for example as coal or smokless solid fuel, and thus it may be desired to convert solid fuel cookers or boilers to oil fired cookers or boilers.However, if the price of oil should dramatically increase, then it may be desired to convert the cookers or boilers back into solid fuel cookers or boilers and this can easily be done with the oil burner apparatus of the present invention.
Advantageously, the burner head faces towards the front of the apparatus. This is in contrast to known oil burner apparatus in which the burner head faces to the rear of the apparatus. By having the burner head facing towards the front of the apparatus, the construction of the conduit means is very simple. The length of the air flow path is reduced to a minimum. A housing containing the conduit means can be produced in approximately half the manufacturing time required to make a housing containing conduit means in known oil burner apparatus in which the burner head faces towards the rear of the apparatus.
The oil burner apparatus may include air adjustment means which operates on suction. This is in contrast to known oil burner apparatus having air adjustment means which works on flow.
The - oil burner apparatus may include an adjustable diffuser tube for the burner head. The adjustable diffuser tube is preferably telescopic.
The adjustable diffuser tube can be pulled out or pushed in until it is of the correct length, and then the various telescopic parts of the adjustable diffuser tube can be secured together, for example by screws or bolts. The distance between the end of the nozzle for spraying the oil and the end of the air diffuser is often critical in giving a good flame and the adjustable diffuser tube enables adjustment to be effected on site and this may be advantageous in easily setting up a good flame.
The oil burner apparatus may advantageously include a plug for disconnecting an electronic circuit part of the apparatus. This facilitates rapid service removal of the oil burner apparatus in the event that a service is required. Usually the plug will be an eight pin plug.
An embodiment of the invention will now be described solely by way of example and with reference to the accompanying drawings in which:
Figure 1 is a perspective view of known oil burner apparatus;
Figure 2 is a side view of the apparatus shown in Figure 1;
Figure 3 is a side view like the side view shown in Figure 1 and illustrates the air path through the oil burner apparatus shown in Figure 1;
Figure 4 is a side view of oil burner apparatus in accordance with the present invention and illustrates the air flow path through the oil burner apparatus;
Figure 5 is a perspective view of the oil burner apparatus shown in Figure 4;
Figure 6 shows a wiring layout for a socket forming part of the oil burner apparatus shown in
Figure 5; and
Figure 7 shows a wiring layout for a plug forming part of the oil burner apparatus shown in Figure 5.
Referring to Figures 1, 2, and 3 there is shown oil burner apparatus 2 comprising a pump motor 4, a fan 6, a burner head 8 and conduit means 10 forming an air flow path 12 between the fan 6 and the burner head 8.
The passage of air along the air flow path 12 is indicated by arrows 14. The pump motor 4 has a pressure regulator 16 provided at one end as shown.
As can be seen from Figures 2 and 3, the burner head 8 is mounted substantially over the pressure regulator 16 so that the conduit means extends first in a vertical direction, then in a horizontal direction and then again in a vertical direction. The air flow path is thus first in a vertical direction, then in a horizontal direction and then in a vertical direction. The air is admitted to the burner head and it will be seen that the burner head faces towards the rear of the oil burner apparatus 2. The oil burner apparatus 2 is such that the air flow path 12 and the entire oil burner apparatus 2 is not too compact.
Furthermore, the oil burner apparatus 2 is provided with air adjustment means 18 which includes a control knob 20 and a rod 22 and it will be seen that the rod 22 is quite long.
Referring now to Figures 4 and 5, there is shown oil burner apparatus 2 in accordance with the present invention. Similar parts as in Figures 1 to 3 have been given the same reference numerals for ease of comparison and understanding.
In Figures 4 and 5, it will be seen that the burner head 8 is mounted substantially over the fan 6 so that the conduit means 10 only has to extend in a vertical direction to form the air flow path 12 between the fan 6 and the burner head 8. It will also "be noted that the burner head 8 faces towards the front of the apparatus.
The oil burner apparatus 2 shown in Figures 4 and 5 may be such as to have air adjustment means (not shown) which operates in the region 24 and which operates on suction. This is in contrast to the air adjustment means 18 shown in Figures 1 and 2 in which the air adjustment means 18 operates on flow.
The oil burner apparatus 2 shown in Figures 4 and 5 also has an adjustable diffuser tube 26. The adjustable diffuser tube 26 is telescopic and it can be pulled out or pushed in for the purposes of varying the distance between the end of a jet nozzle 4 spraying kerosene or other oil and an end of the air diffuser tube 26. This enables a good flame easily to be set up during installation of the oil burner apparatus 2.
The oil burner apparatus 2 of the present invention may have a high temperature ceramic board shroud (not shown).
The oil burner apparatus 2 is advantageously used as a conversion kit for converting known cookers and boilers operating on solid fuel into cookers and boilers operating on oil. The cookers and boilers can be converted back again so that they become multi-fuel 'cookers and boilers.
The oil burner apparatus 2 of the present invention is a pressure jet oil burner apparatus 2 and it is much more compact than the known oil burner apparatus 2 as can be seen from a comparison of the dimensions given on Figures 1 and 5. For example, because the horizontal run of the conduit means 10 in
Figure 1 is dispensed with in Figure 5, a saving of 40mm can be achieved. With the oil burner apparatus 2 of the present invention, the flame may start lower in the boiler and it may be more efficient since hot air will travel longer and may engage a water jacket at a lower position. Furthermore, the compactness of the oil burner apparatus 2 of the present invention enables it to fit in smaller, for example lower, spaces.
The pressure regulator 16 of the oil burner apparatus 2 of the present invention may have an air bleed screw 28.
A plate part 30 of the oil burner apparatus 2 of the present invention may be provided with an eight pin and socket plug device (not shown) which can simply be unplugged in order to disconnect the illustrated part of the oil burner apparatus 2 from an electronic circuit. This facilitates easy removal of the illustrated oil burner apparatus 2 for maintenance or repair purposes. In the known oil burner apparatus 2 shown in Figure 1, disconnection from the electronic circuit part of the apparatus involves the separate disconnection of eight wires and this is time consuming and inconvenient.
Figure 6 is a self explanatory wiring diagram for the socket. Figure 7 is a self explanatory wiring diagram for a plug. The socket is provided on the oil burner apparatus 2. The plug goes back to a controller which may be wall mounted.
It is to be appreciated that the embodiment of the invention described above with reference to the accompanying drawings has been given by way of example only and that modifications may be effected. Thus, for example, the oil burner apparatus may be fitted in various types and designs of cookers and boilers and the present invention also extends to the cookers and boilers when provided with the oil burner apparatus. The compactness of the oil burner apparatus enables it to sit lower on the water jacket which is advantageous for giving an efficient heat transfer. Preferably electrodes for the oil burner apparatus are fastened directly on to the nozzle holder, instead of on the flame ring as
in the known oil burner apparatus shown in Figure 1.
