Title:
BATHTUB HEATER
Document Type and Number:
WIPO Patent Application WO/2009/147374
Kind Code:
A3
Abstract:
A system for heating a bathtub (10) comprising a heating element (1)1 applied to at least one wall of the bathtub (10). The heating element (11) can be applied on the exterior wall or within the wall of the bathtub (10). The system is further calibrated for measuring the rate of change in temperature of the bathtub and correlating this rate of change to the amount or depth of water in the bathtub. The rate of change can be the rate in rise of temperature or the rate of cooling of the bathtub. A database or look-up table is established showing the different rates of change in temperature to the amount or depth of water in the bathtub. Techniques such as 'fuzzy logic' can be used to continually update the database and to correlate the rate in change of temperature of the bathtub to the amount or depth of water in the bathtub.
