Thermoelectric personal environment appliance
View Patent ↗A personal environment appliance is disclosed in which a person in a work area can individually control the ambient conditions of that persons localized work space environment. The control permits highly localized adjustment to suit individual preferences, thereby, reducing the impact of individual environmental preferences on the individuals. In addition to environment conditions, a variety of accessories may be provided such as beverage heaters and/or coolers.
1. A personal environment appliance that provides heating and/or cooling in a localized area, the personal environment appliance comprising:
at least one electric motor driving at least one fan;
at least one inlet air path to a low pressure side of the at least one fan;
a thermoelectric device having a first side and a second side;
a first plurality of fin heat exchangers in thermal communication with the first side of the thermoelectric device, wherein inlet air passes the first plurality of fin heat exchangers along a first direction of flow and changes temperature, the first plurality of fin heat exchangers substantially thermally isolated from one another in the first direction; and
at least one outlet for the air that has passed the first plurality of fin heat exchangers to provide temperature control of the localized area.
2. The personal environment appliance of claim 1 , wherein the at least one inlet air path is formed by an insulative member.
3. The personal environment appliance of claim 1 , further comprising at least one air filter.
4. The personal environment appliance of claim 3 , wherein the air filter comprises an electrostatic filter.
5. The personal environment appliance of claim 3 , wherein the air filter comprises activated charcoal.
6. The personal environment appliance of claim 1 , further comprising at least one flow directing device for the at least one outlet.
7. The personal environment appliance of claim 1 , further comprising at least one AC to DC power supply.
8. The personal environment appliance of claim 1 , wherein the appliance is constructed to rest on a surface.
9. A personal environment appliance that provides heating and/or cooling in a localized area, the personal environment appliance comprising:
at least one electric motor driving at least one fan;
at least one inlet air path to a low pressure side of the at least one fan;
a thermoelectric device having a first side and a second side;
a first plurality of fin heat exchangers in thermal communication with the first side of the thermoelectric device, wherein inlet air passes the first plurality of fin heat exchangers along a first direction of flow and changes temperature, the first plurality of fin heat exchangers substantially thermally isolated from one another in the first direction;
at least one outlet for the air that has passed the first plurality of fin heat exchangers to provide temperature control of the localized area; and
a second plurality of fin heat exchangers in thermal communication with the second side of the thermoelectric device, wherein waste air passes the second plurality of fin heat exchangers along a second direction of flow and changes temperature, the second plurality of fin heat exchangers separated from one another in the second direction of flow by gaps.
10. The personal environment appliance of claim 9 , wherein the first direction of flow and the second direction of flow are in opposite directions.
