Abstract

Voice commands of two types are recognized by an air conditioner: (1) a first command to jump to a different air delivery (below-out) temperature, after which a gradual automatic return to the previously set temperature occurs, or (2) a second command which will stop the automatic return at some arbitrary temperature.

Claims

1. Apparatus for controlling an air conditioner by voice command, the apparatus comprising:

(a) air mixing means for mixing cool air and hot air introduced to a space to adjust a temperature of air delivered from the air conditioner;

(b) voice recognizing means for recognizing a voice command and for delivering a command signal corresponding to the voice command, said voice command representing one of a command to increase the delivered air temperature and a command to decrease the delivered air temperature; and

(c) control means for controlling said mixing means such that the delivered air temperature is stepwise increased in response to a command signal to increase the temperature and then is gradually decreased until the delivered air temperature is returned to a previously set level, and the delivered air temperature is stepwise decreased in response to a command signal to decrease the temperature and then is gradually increased until the delivered air temperature is returned to a previously set level.

2. Apparatus for controlling an air conditioner by voice command according to claim 1, further comprising a display means responsive to said corresponding command signal for displaying an indication representative of said voice command.

3. Apparatus for controlling an air conditioner by voice command according to claim 1, wherein said control means comprises a calculating means, said calculating means calculating a desired temperature of the delivered air in accordance with various parameters including at least an internal temperature of said space, an ambient air temperature, and a set temperature changed by corresponding command signal and producing a temperature signal according to the thus calculated temperature.

4. Apparatus for controlling an air conditioner by voice command according to claim 3, further comprising a display means responsive to said corresponding command signal for displaying an indication representative of said voice command.

5. Apparatus for controlling an air conditioner by voice command according to claim 3, wherein while said set temperature is being changed in response to one vocal announcement, no change of said set temperature is obtainable in response to another voice announcement.

6. Apparatus for controlling an air conditioner by voice command according to claim 3, wherein while said temperature of the delivered air is being controlled by the voice, no change of set temperature is obtainable by manual operation.

7. Apparatus for controlling an air conditioner by voice command according to claim 6, further comprising a display means responsive to said corresponding command signal for displaying an indication representative of said voice command.

8. Apparatus for controlling an air conditioner by voice command, the apparatus comprising:

(a) mixing means for mixing cool air and hot air introduced to a space so as to adjust a temperature of air delivered from the air conditioner;

(b) a voice recognizing means for recognizing a voice command and for delivering a command signal corresponding to the voice command, said voice command representing one of a command to increase the delivered air temperature, a command to decrease the delivered air temperature, and a command to interrupt a change of the delivered air temperature; and

(c) control means for controlling said mixing means such that the temperature is stepwise increased in response to a command signal representative of a command to increase the temperature and then is gradually decreased for a predetermined period of time, and the temperature is stepwise decreased in response to a command signal representative of a command to decrease the temperature and then is gradually increased for a predetermined period of time, and for controlling said mixing means such that the temperature is maintained as it is in response to a command signal representative of a command to interrupt a change of the temperature received by said voice recognizing means within said predetermined period of time.

9. Apparatus for controlling an air conditioner by voice command according to claim 8, further comprising a display means responsive to said corresponding command signal for displaying an indication representative of said voice command.

10. Apparatus for controlling an air conditioner by voice command according to claim 8, wherein said control means comprises a calculating means, said calculating means calculating a desired temperature of the delivered air in accordance with various parameters including at least an internal temperature of said space, an ambient air temperature, and a set temperature changed by corresponding command signal and producing a temperature signal according to the thus calculated temperature.

11. Apparatus for controlling an air conditioner by voice command according to claim 10, further comprising a display means responsive to said corresponding command signal for displaying an indication representative of said vocal information.

12. Apparatus for controlling an air conditioner by voice command according to claim 10, wherein while said set temperature is being changed in response to one vocal announcement, no change of said set temperature is obtainable in response to another voice announcement.

13. Apparatus for controlling an air conditioner by voice command according to claim 10, wherein while said temperature of the air is being controlled by the voice, no change of set temperature is obtainable by manual operation.

14. Apparatus for controlling an air conditioner by voice command according to claim 13, further comprising a display means responsive to said corresponding command signal for displaying an indication representative of said vocal information.
