Abstract
An air deodorizing assembly including a frame having a liquid reservoir; a filter element connected to the frame; and a switch actuator connected to the frame. The switch actuator is adapted to cause an open electrical path to close when the frame is located proximate the open electrical path.
Claims19
An air deodorizing assembly comprising:
- a frame comprising a liquid deodorizer reservoir;
- a filter element connected to the frame;
- and
- a switch actuator connected to the frame, wherein the switch actuator is adapted to cause an open electrical path to close when the frame is located proximate the open electrical path.
1 more element
A system for deodorizing air comprising:
- a housing;
- a fan connected to the housing;
- a removable combined air filter and liquid deodorizer cartridge connected to the fan;
- and
- an electrical circuit, connected to an electrical power supply, for supplying electrical power to the fan,
- wherein the cartridge and the electrical circuit form a switch in the electrical circuit which is closed by presence of the cartridge at a predetermined position in the housing, wherein the switch is open when the cartridge is not located at the predetermined position in the housing, and wherein operation of the fan is dependent upon the switch being closed such that proper positioning of the cartridge in the housing at the predetermined position is required in order to allow the fan to operate.
3 more elements
A method of operating an air deodorizing system comprising steps of:
- inserting a removable combined air filter and liquid deodorizer reservoir cartridge into a housing of the air deodorizing system;
- and
- closing an open electrical path of an electrical circuit to a fan of the air deodorizing system when the cartridge is inserted into the housing in a predetermined position, the predetermined position comprising a magnet on the cartridge being located proximate a reed switch of the electrical circuit.
A method of operating an air deodorizing system comprising steps of:
- inserting a removable combined air filter and liquid deodorizer reservoir cartridge into a housing of the air deodorizing system;
- and
- closing an open electrical path in an electrical circuit to a fan of the air deodorizing system when the cartridge is inserted into the housing in a predetermined position, the predetermined position comprising an electrical conductor on the cartridge contacting a pair of electrical contacts of the electrical circuit to close the open electrical path between the contacts.
