Abstract
The present invention provides a boiler unit comprising a heater chamber housing a heater element. The heater element is configured to heat water retained within the heater chamber to generate steam. The boiler unit further comprises a pair of separated electrodes located within the heater chamber. The boiler unit is configured to measure an electrical value corresponding to either the resistance between the pair of separated electrodes or another electrical value that is proportionate to the resistance between the pair of separated electrodes. The boiler unit is further configured to determine whether the water level in the heater chamber relative to the pair of separated electrodes is too low using the measured electrical value.
Claims (19)
1. A boiler unit comprising: a heater chamber housing a heater element, the heater element configured to heat water retained within the heater chamber to generate steam; and a pair of separated electrodes located within the heater chamber; wherein the boiler unit is configured: to measure an electrical value corresponding to either the resistance between the pair of separated electrodes or another electrical value that is proportionate to the resistance between the pair of separated electrodes; and to determine whether the water level in the heater chamber relative to the pair of separated electrodes is too low using the measured electrical value.
2. The boiler unit of claim 1 , wherein the boiler unit is further configured to compare the measured electrical value to a predetermined value to determine whether the water level is too low relative to the pair of separated electrodes.
3. The boiler unit of claim 1 or 2, wherein at least one electrode of the pair of separated electrodes is positioned proximate an uppermost edge of the heater element.
4. The boiler unit of any preceding claim, wherein at least one electrode of the pair of separated electrodes is positioned at the same height as the uppermost edge of the heater element.
5. The boiler unit of any preceding claim, wherein a first electrode of the pair of separated electrodes extends inwardly from the inner surface of the heater chamber.
6. The boiler unit of any of claim 1 to 4, further configured such that the heater element or the inner surface of the heater chamber is the first electrode of the pair of separated electrodes or a second electrode of the pair of separated electrodes.
7. The boiler unit of any preceding claim, wherein a flash heater provides the heater chamber and the heater element.
8. The boiler unit of any preceding claim wherein, when the boiler unit determines that the water level relative to the electrodes is too low, the boiler unit is configured to allow more water to flow into the heater chamber.
9. The boiler unit of claim 8 wherein the boiler unit is configured such that, when the boiler unit is allowing water to flow into the heater chamber, the boiler unit prevents more water from flowing into the heater chamber if the boiler unit determines that the water level in the heater chamber relative to the pair of separated electrodes is no longer too low.
10. The boiler unit of claim 9, wherein the boiler unit is configured to continue determining whether the water level in the heater chamber relative to the pair of separated electrodes is too low such that the boiler unit operates repeated cycles of allowing and preventing water to flow into the heater chamber.
11 . The boiler unit of any preceding claim wherein, when the boiler unit determines that the water level relative to the electrodes remains too low for longer than a predetermined period, the boiler unit is further configured to switch off the heater element automatically and/or prevent water from flowing into the heater chamber.
12. An apparatus for steaming animal fodder, such as a hay steamer, comprising the boiler unit of any preceding claim.
13. The apparatus of claim 12, wherein the boiler unit is (a) housed in or attached to the main body of the apparatus so as to form an integral unit, or (b) a separate unit connected to the main body of the apparatus by a conduit adapted for carrying steam generated in the boiler unit.
14. A method of determining whether a water level in a heater chamber of a boiler unit is too low relative to a pair of separated electrodes located within the heater chamber, the method comprising: measuring an electrical value corresponding to either the resistance between the pair of separated electrodes or another electrical value that is proportionate to the resistance between the pair of separated electrodes; and determining whether the water level relative to the pair of separated electrodes is too low using the measured electrical value.
15. The method of claim 14, wherein determining whether the water level relative to the pair of separated electrodes is too low using the measured electrical value comprises comparing the measured electrical value to a predetermined value.
16. The method of claim 14 or 15 wherein, when the water level relative to the electrodes is determined to be too low, more water is allowed to flow into the heater chamber.
17. The method of claim 16 wherein, while water is being allowed to flow into the heater chamber, the flow of water into the heater chamber is prevented if the water level in the heater chamber relative to the pair of separated electrodes is no longer determined to be too low.
18. The method of claim 17, further comprising continuing determining whether the water level in the heater chamber relative to the pair of separated electrodes is too low thereby implementing repeated cycles of allowing and preventing water to flow into the heater chamber.
19. The method of any of claims 14 to 18 further comprising, when the water level relative to the electrodes is determined to remain too low for longer than a predetermined period, automatically switching off the heater element and/or preventing water from flowing into the heater chamber.
