THERMOELECTRIC WATER COOLER WITH FILTER MONITOR SYSTEM

摘要

A filter monitor system is provided in a bottled water cooler (35) for automatically tracking a filter service interval, and for indicating that filter cleaning or replacement is required for continued efficient cooler operation. In the preferred form, the water cooler i(10) ncludes a thermoelectric chiller module (16) for chilling at least a portion of water contained within a cooler reservoir (12). An air filter (22) is mounted on a filter frame which is removably positioned for filtering air drawn by a fan (20) to circulate over a heat sink (18) associated with the thermoelectric chiller module (16). The filter monitor system includes a reset switch engaged by the filter frame to initiate and track a predetermined filter service time interval, such as thirty days, and to energize a signal such as an indicator light at the conclusion of this service interval to indicate that the air filter (22) should be removed for cleaning or replacement.
