Abstract
An air cleaner with a smoke alarm unit for a forced air recirculating system is disclosed. The smoke alarm unit is housed within a module that fits within the frame of the air cleaner with minimal impact on the cleaning ability of the cleaner. In a preferred embodiment of the invention, a battery capacity tester and air cleaner functionality detector are included in the module. Signals from the battery tester and functionality detector are used by the smoke alarm unit to drive an alarm generator with different signals to produce distinguishable alarms for a smoke condition, low battery condition, and an air cleaner failure. A control unit may receive any of the alarm conditions to execute different control actions in the forced air system.
Claims29
A smoke alarm and air cleaning device for use in a forced recirculating air conditioning system having a blower comprising:
- means for cleaning the air,
- means for generating an alarm in response to smoke in the air, and
- means for integrating said air cleaning means with said alarm generating means so that both said means for cleaning the air and generating the alarm intercept recirculating air within the system for cleaning the air and smoke detection.
An air cleaner monitoring circuit for a forced air conditioning system in a building, the system having at least one blower and a duct connected to the blower to circulate air throughout the building, comprising
- means for cleaning the air in said system,
- means for generating an alarm in response to smoke in the circulating air,
- an electrical power source electrically connected to said smoke alarm means,
- means for detecting and reporting low electrical energy capacity when the electrical energy capacity of said electrical power source falls below a predetermined level,
- means for detecting and reporting cleaning means failure predetermined threshold;
- and
- means for integrating both said detecting and reporting means with one another in the forced air conditioning system.
An air cleaner monitoring circuit for a forced air conditioning system in a building, the system having at least one blower and a duct connected to the blower to circulate air throughout the building, the duct having an air cleaning device amounted therein to clean the recirculating air, comprising
- means for generating an alarm in response to smoke in the circulating air,
- an electrical power source electrically connected to said smoke alarm means,
- means for detecting and reporting low electrical energy capacity when the electrical energy capacity of said electrical power source falls below a predetermined level,
- means for detecting and reporting cleaning means failure when the functionality falls below a predetermined threshold, and
- means for integrating both said detecting and reporting means in the forced air conditioning system.
