Abstract

A set back timer for an air conditioner is provided with a display screen (15) for the representation of information about normal and set back operations of the air conditioner, wherein a normal operation time period display (53) indicating a time period of the day during which period a normal operation is carried out and a set back time period display (64) indicating a time period in the normal operation time period during which period a set back operation is carried out are displayed independently of each other on the display screen (15). Such arrangement enables an air conditioner user to easily and correctly confirm, at a glance, the relationship between a normal operation time period and a set back operation time period in the normal operation time period for the day, and the contents of a setting can be confirmed remarkably easily, thereby contributing to improvements in air conditioner operability.

Claims

1. A set back timer for an air conditioner for performing control operations so that there is a temperature shift to a second set temperature only in a specified time period in a time period during which period a normal operation is carried out based on a first set temperature, said air conditioner set back timer comprising:

a display screen (15) for the representation of information about normal and set back operations of said air conditioner,

wherein a normal operation time period display (53) indicating a time period of the day during which period a normal operation is carried out and a set back time period display (64) indicating a time period in said normal operation time period during which period a set back operation is carried out are displayed independently of each other on said display screen (15).

2. The air conditioner set back timer of claim 1, wherein said set back time period display (64) is displayed adjacently to said normal operation time period display (53).

3. The air conditioner set back timer of claim 1, wherein said set back time period display (64) is displayed in the vicinity of said normal operation time period display (53).

4. The air conditioner set back timer of any one of claims 1-3, wherein said normal operation time period display (53) and said set back time period display (64) are each displayed in a bar chart-like display manner in which time periods of the day are continuously represented.

5. The air conditioner set back timer of any one of claims 1-4, wherein said normal operation time period display (53) and said set back time period display (64) are made contrastable with each other by hour.

6. The air conditioner set back timer of any one of claims 1-5, wherein said normal operation time period display (53) and said set back time period display (64) are provided with time indexes (54) and (65), respectively, for every two hours.

7. The air conditioner set back timer of any one of claims 1-6, wherein said first set temperature (52) and said second set temperature (63) are displayed in the vicinity of said normal operation time period display (53) and in the vicinity of said set back time period display (64), respectively.

8. The air conditioner set back timer of claim 1, wherein a day display (44) is displayed on said display screen (15) which indicates the presence or absence of an air conditioner operation for each day of the week.

9. The air conditioner set back timer of claim 8, wherein said day display (44) displays each day of the week by its first three letters.

10. An air conditioning system formed by combining any one of said air conditioner set back timers of claims 1-9 and an air conditioner.

11. A display setting method for a set back timer of an air conditioner wherein said set back timer performs control operations so that there is a temperature shift to a second set temperature only in a specified time period in a time period during which period a normal operation is carried out based on a first set temperature, said method comprising the step of:

independently displaying a normal operation time period display (53) indicating a time period of the day during which period a normal operation is carried out and a set back time period display (64) indicating a time period in said normal operation time period during which period a set back operation is carried out, on a display screen (15) of said set back timer for the representation of information about normal and set back operations of said air conditioner.
