Variable speed, electronically controlled, room air conditioner
First Claim
1. An air handling system for heating and/or cooling a room, the system comprising:
- a user interface for transmitting a sleep mode signal upon activation of a sleep mode by a user;
a climate control unit for heating and/or cooling air to be transported from the climate control unit to the room, the climate control unit comprising a motor comprising a single main stator winding for driving a fan; and
a control unit for controlling the climate control unit to gradually change an ambient temperature in the room over a predetermined period of time in response to the sleep mode signal transmitted by the user interface, wherein the control unit incrementally adjusts a set temperature of the air handling system in a plurality of increments toward a target sleep temperature, each of the increments having a predetermined duration, and modulates an electric power signal in response to an operator input instruction to be delivered to the single main stator winding for providing substantially-continuous adjustment of a speed of the fan from a first fan speed to a second fan speed that is different from the first fan speed to control the gradual change of the ambient temperature in the room, wherein substantially-continuous adjustment of the speed of the fan comprises substantially-infinitely adjusting the speed to any desired speed between predetermined upper and lower speed limits.

Abstract
An air handling system for cooling and/or heating a room includes a sleep mode. The system includes a fan assembly to transport air from the system into the room. A user interface transmits a sleep mode signal upon activation of the sleep mode by a user. A control unit controls the climate control unit to gradually change an ambient temperature in the room over a predetermined period of time in response to the sleep mode signal transmitted by the user interface. Further, the fan assembly has a substantially continuously adjustable speed within a range of speeds defined by a predetermined upper limit and a predetermined lower limit. The control unit adjusts the speed of the fan assembly according to a desired speed of the fan assembly input via the user interface. A multi-position switch defines the predetermined upper and lower limits.

12. A variable speed air handling system for a room, the air handling system comprising:
-
a fan assembly to transport air from the air handling system into the room, the fan assembly having a substantially continuously adjustable speed within a range of speeds defined by a predetermined upper limit and a predetermined lower limit, wherein substantially continuously adjusting the speed comprises generally continuously and smoothly adjusting the speed from a first operational fan speed to a second operational fan speed in a substantially variable analog manner; a user interface for inputting at least a desired speed of the fan assembly; a control unit for modulating an electrical signal to be supplied to the fan assembly for substantially continuously adjusting the speed of the fan assembly in the substantially variable analog manner from the first operational fan speed to the second operational fan speed that is different from the first operational speed according to the desired speed of the fan assembly input via the user interface; and a multi-position switch for defining the predetermined upper and lower limits at opposite ends of an allowable range of fan speeds to which the fan assembly can be substantially continuously adjusted in the analog manner by the control unit in response to requests entered via the user interface. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)

21. A variable speed air handling system for a room, the air handling system comprising:
-
a fan assembly to transport air from the air handling system into the room; a user interface for inputting at least a desired speed of the fan assembly; a control unit for modulating an electrical power signal delivered to the fan assembly to substantially continuously adjust the speed of the fan assembly in suitably fine increments from a first speed to the desired speed that is different from the first speed to approach an analog adjustment of the speed of the fan to achieve the desired speed of the fan motor input via the user interface, wherein the desired speed of the fan motor can be virtually any speed between predetermined upper and lower limits; an air filter that removes debris from the air being transported from the system into the room; and a filter check indicator for notifying a user to check the air filter. - View Dependent Claims (22, 23, 24, 25)
