Air-conditioning remote controller and air-conditioning system

1. An air-conditioning remote controller capable of controlling a plurality of models of air-conditioners, comprising:

an input unit via which a setting value for one or more setting items to control operation of an air-conditioner is inputted; and

a display unit including a predefined area in which a plurality of icons are displayed to visually represent the setting value for a corresponding setting item, where a number of the plurality of icons displayed is determined based on the inputted setting value and a total number of taps for the corresponding setting item for a model of a main body of the air-conditioner, wherein

the display unit sets a maximum displayable number of the icons to be equal to or higher than the total number of taps for the corresponding setting item for the model of the main body of the air-conditioner to be controlled using the setting value.

2. The air-conditioning remote controller according to claim 1 , wherein as the maximum displayable number of the icons decreases, an area of each icon displayed in the predefined area becomes larger.

3. The air-conditioning remote controller according to claim 1 , wherein

the total number of taps is a number of airflow rate taps indicating an airflow rate of the air-conditioner, and

the air-conditioning remote controller further comprises:

a storage unit configured to store initial setting information including the number of the airflow rate taps; and

a processing unit configured to display, on the display unit, setting information of the airflow rate inputted via the input unit,

by vertically dividing the predefined area into sub-areas by the number of the airflow rate taps, and

displaying the setting information of the airflow rate using a trapezoid displayed in each of the sub-areas, where the trapezoid has a pair of mutually parallel opposite sides at the top and bottom, and each of the trapezoids has an area larger than an area of a trapezoid vertically immediately above.

4. The air-conditioning remote controller according to claim 3 , wherein

the processing unit is configured to display the trapezoids on the display unit,

by displaying a same number of the trapezoids as the number of the airflow rate taps in a first color; and

displaying the setting information of the airflow rate in a second color different from the first color.

5. The air-conditioning remote controller according to claim 3 , wherein

the processing unit is configured to display the trapezoids on the display unit, while displaying a numeral indicating the setting information of the airflow rate in a vicinity of the trapezoids.

6. The air-conditioning remote controller according to claim 3 , wherein

each of the trapezoids displayed on the display unit has one pair of opposite sides in the left-right direction and at least one side of the one pair of the opposite sides of each of the trapezoids is aligned on a straight line.

7. The air-conditioning remote controller according to claim 3 , wherein the processing unit is configured to collect air-conditioner information including the number of the airflow rate taps from the main body of the air-conditioner via a communication unit and to store the air-conditioner information in the storage unit.

8. An air-conditioning remote controller capable of controlling a plurality models of air-conditioners, comprising:

a display unit configured to display setting information for a main body of an air-conditioner;

a storage unit configured to store initial setting information including a number of airflow rate taps being displayable on the display unit;

an input unit configured to receive an input; and

a processing unit configured to display setting information of the airflow rate inputted via the input unit on the display unit,

by vertically dividing a predefined area into sub-areas by the number of the airflow rate taps, and

displaying the setting information of the airflow rate using a trapezoid displayed in each of the sub-areas, where the trapezoid has a pair of mutually parallel opposite sides at the top and bottom, and each of the trapezoids has an area larger than an area of a trapezoid vertically immediately above, wherein

the display unit sets a maximum displayable number of the trapezoids in the predefined area to be equal to or higher than the stored number of airflow rate taps.

9. An air conditioning system comprising:

the air-conditioning remote controller and the main body of the air-conditioner, according to claim 1 .

10. An air conditioning system comprising:

the air-conditioning remote controller and the main body of the air-conditioner, according to claim 2 .

11. An air conditioning system comprising:

the air-conditioning remote controller and the main body of the air-conditioner, according to claim 3 .

12. An air conditioning system comprising:

the air-conditioning remote controller and the main body of the air-conditioner, according to claim 4 .

13. An air conditioning system comprising:

the air-conditioning remote controller and the main body of the air-conditioner, according to claim 5 .

14. An air conditioning system comprising:

the air-conditioning remote controller and the main body of the air-conditioner, according to claim 6 .

15. An air conditioning system comprising:

the air-conditioning remote controller and the main body of the air-conditioner, according to claim 7 .

16. An air conditioning system comprising:

the air-conditioning remote controller and the main body of the air-conditioner, according to claim 8 .
