Abstract
An appliance for delivering agent. The agent-delivery appliance includes an agent-releasing mechanism, an air-moving device that generates a flow of air moving from upstream to downstream, and at least one filter. The agent-releasing mechanism includes a chamber configured to release agent into the flow of air generated by the air-moving device. The chamber includes multiple openings, one of which is configured to provide air loaded with agent from the chamber to a first location within the flow of air generated by the air-moving device. At least one filter is located upstream from the first location within the flow of air generated by the air-moving device.
Claims25
An agent-delivery appliance comprising:
- a housing having at least one air inlet and at least one air outlet;
- an air-moving device disposed within the housing and configured to generate a flow of air that moves from upstream to downstream such that the flow of air enters the housing through at least one air inlet and exits the housing through at least one air outlet;
- at least one filter;
- and
- an agent-releasing mechanism disposed within the housing;
- wherein the agent-releasing mechanism comprises a chamber configured to release an agent;
- and
- wherein the chamber comprises a plurality of openings, at least one of the openings configured to provide air loaded with agent from the chamber to a first location within the flow of air generated by the air-moving device;
- and
- wherein at least one filter is disposed upstream from the first location within the flow of air.
An agent-delivery appliance comprising:
- a housing having at least one air inlet and at least one air outlet;
- an air-moving device disposed within the housing and configured to generate a flow of air that moves from upstream to downstream;
- an agent-releasing mechanism disposed external to the housing;
- wherein the agent-releasing mechanism comprises a chamber configured to release an agent;
- and
- wherein the chamber comprises a plurality of openings, at least one of the openings configured to provide air loaded with agent from the chamber to a first location within the flow of air generated by the air-moving device;
- and
- wherein at least one filter is disposed upstream from the first location within the flow of air.
An agent-delivery appliance comprising:
- a housing having an air inlet and an air outlet;
- a fan disposed within the housing and configured to generate a flow of air that moves from upstream to downstream such that the flow of air enters the housing through the air inlet and exits the housing through the air outlet;
- an agent-releasing mechanism coupled to the housing and configured to release an agent;
- a first filter disposed near the air inlet;
- and
- a second filter disposed downstream from the first filter;
- wherein:
- the agent-releasing mechanism comprises a chamber configured to accept an agent cartridge containing the agent;
- the chamber comprising a first opening, a second opening, and a user-controllable airflow adjustment device;
- the first opening being configured to input air into the chamber;
- the second opening being configured to provide air loaded with agent from the chamber to a first location within the flow of air generated by the fan;
- the user-controllable airflow adjustment device being configured to control an effective surface area of the second opening;
- the first filter comprising a pre-filter including activated carbon;
- and
- the second filter comprising a paper filter being configured to remove particulate matter and being disposed upstream from the first location within the flow of air.
