<p>An infant care apparatus that has a canopy (30) that can be moved vertically with respect to an infant platform (20) on which the infant is positioned. The canopy (30) contains a radiant heater (35) that can be moved from a lower position (Figure 1) enclosing the infant in an infant compartment to an upper position (Figure 3) where the infant compartment is open and the radiant heater (35) provides radiant energy to warm the infant. When the canopy is in its lower position there is a convective heating system (42-50) that provides a forced flow of heated air to the infant compartment to heat the infant. The convective heating system (42-50) includes a heater (44), a fan (46) and various ducting and passageways (42) in the infant platform that conduct the heated air to the infant compartment and receive air from that compartment for re-circulation. A control system is used to operate both the convective heating system (42-50) and the radiant heater (35) and is operable to activate the radiant heater and disable the convective heating system (42-50) when the canopy (30) is in its upper position and, conversely, to activate the convective heating system (42-50) and disable the radiant heater (35) when the canopy is in its lower position. In the preferred embodiment, when the convective heating system (42-50) is disabled, the control system has a separate control of the heater (44) and the fan (46) of the convective heating system and can inactivate the convective heating system by shutting off the fan while retaining the heater energized at a relative low setting of heat output, thus the heater (44) can keep the various ducting and passageway surfaces (42) warm and improve the warm up time that the convective heating system (42-50) takes to warm up the infant compartment with heated forced air when the canopy (30) is returned to is lower position and the convective heating system (42-50) again activated.</p> |
