Comfort bathtub with heated wall portions

摘要

A comfort bathtub has at least one heated wall portion which is comprised by a composite pliable heat generating envelope integrated with the wall portion. The heat generating envelope has a heated mesh sandwiched between a pair of protection film sheets bonded together about the heated mesh to isolate the heated mesh from molded material of the bathtub. The composite pliable envelope has electrical connections secured to a power supply. A temperature sensor is in communication with the envelope for sensing the temperature thereof. A voltage regulator controls the power supply through a control circuit to regulate the heat generated by the heated mesh. The composite pliable envelope is configured to heat a discrete wall portion of the bathtub to provide a discrete external heated surface of the bathtub.
