Abstract

Abstract An air direction control apparatus comprises a remote controller having an air direction change operation section and a transmitting section for transmitting a control signal intermittently after a drive instruction signal from the air direction change operation section has been detected, and an associated device responsive to the control signal to analyze its contents and, if there is a louver drive signal, drive a louver motor to permit the louver slats to be controlled so that the direction of air at an air inlet is changed.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 233 words
An air direction control apparatus for a louver at an air outlet of an air conditioner, comprising: a remote control including a direction change operation section for issuring an air direction change operation instruction, operation detection means connected to said direction change operation section for detecting said air direction change instruction, first timer means which is initiated and stopped in reponse to the appearance and disappearance of said air direction change instruction for generating a first timer output every time a first period of time has elasped, and an intermittent signal generating means for intermittently geneating a remote control signal including a louver control signal in response to said timer output, and transmitting means for transmitting said intermittently generated remote control signal; receiving means for receiving said remote control signal transmitted from said remote controller; detection means for detecting the louver control signal included in said received remote control signal; second timer means for measuring a second period of time longer than said first period of time; drive signal output means for outputting a drive signal in response to said detected louver control signal for the time period meansured by said second timer means; louver motor means driven by the drive signal outputted from said drive signal output means; and louver means driven by said louver motor to permit an air direction at an air outlet of the air conditioner to be contolled.
Claim 2
Dependent Claim 233 words
An air direction control apparatus for a louver at an air outlet of an air conditioner, comprising: a remote control including a direction change operation section for issuring an air direction change operation instruction, operation detection means connected to said direction change operation section for detecting said air direction change instruction, first timer means which is initiated and stopped in reponse to the appearance and disappearance of said air direction change instruction for generating a first timer output every time a first period of time has elasped, and an intermittent signal generating means for intermittently geneating a remote control signal including a louver control signal in response to said timer output, and transmitting means for transmitting said intermittently generated remote control signal; receiving means for receiving said remote control signal transmitted from said remote controller; detection means for detecting the louver control signal included in said received remote control signal; second timer means for measuring a second period of time longer than said first period of time; drive signal output means for outputting a drive signal in response to said detected louver control signal for the time period meansured by said second timer means; louver motor means driven by the drive signal outputted from said drive signal output means; and louver means driven by said louver motor to permit an air direction at an air outlet of the air conditioner to be contolled.
Claim 3
Dependent Claim 173 words
A control apparatus for controlling an operation of a louver at an air outlet of an air conditioner, comprising: a remote controller for transmitting a single remote control signal which is generated in accordance with a single operation of a push button, said remote controller including means for generating a louver operation instruction and a louver stop instruction which are successively generted in reponse to successive operation of a push button; receiving means for receiving said remote control signal transmitted from said remote controller; detection means for detecting the louver operation instruction and the louver stop instruction included in said receiver remote control signal; drive signal output means for outputting a drive signal in response to said detected louver operation signal; louver motor means driven by the drive signal; louver means driven by said louver motor means to direct air at a direction from an air outlet of the air conditioner; and stopping means for stoping the louver motor means thereby stoping the louver means in reponse to the detected louver stop instruction.
Claim 4
Dependent Claim 173 words
A control apparatus for controlling an operation of a louver at an air outlet of an air conditioner, comprising: a remote controller for transmitting a single remote control signal which is generated in accordance with a single operation of a push button, said remote controller including means for generating a louver operation instruction and a louver stop instruction which are successively generted in reponse to successive operation of a push button; receiving means for receiving said remote control signal transmitted from said remote controller; detection means for detecting the louver operation instruction and the louver stop instruction included in said receiver remote control signal; drive signal output means for outputting a drive signal in response to said detected louver operation signal; louver motor means driven by the drive signal; louver means driven by said louver motor means to direct air at a direction from an air outlet of the air conditioner; and stopping means for stoping the louver motor means thereby stoping the louver means in reponse to the detected louver stop instruction.
