DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operation control device for an air conditioner.

[0002]

2. Description of the Related Art Conventionally, an operation start time is determined according to a detection value of a room temperature sensor at a set time of an on-timer set by an on-timer so that a room temperature reaches a desired temperature control state. I was driving up.

[0003]

In the above-mentioned conventional air conditioner, the start time of the warm-up operation is uniquely determined according to the room temperature. However, there is a problem that the room temperature may not be in a desired temperature control state.

[0004]

DISCLOSURE OF THE INVENTION The present invention has been made to solve the above problems, and its gist is to provide a room temperature sensor and an input timer, and to detect the detected value of the room temperature sensor. The operation control device of the air conditioner that determines the operation start time so that the room temperature becomes a desired temperature control state at the ON timer set time set by the ON timer in response to the warming-up operation of the air conditioner, Temperature difference detecting means for detecting a temperature difference between the set temperature and the room temperature at the set time, and changing means for changing the operation start time of the next on-timer operation according to the detected temperature difference. An operation control device of an air conditioner characterized by the above.

[0005]

According to the present invention, since the above configuration is provided, the operation time of the next ON timer operation is changed according to the temperature difference between the set temperature at the ON timer set time and the room temperature.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be specifically described with reference to the drawings. FIG. 1 shows a control block diagram, and FIG.
FIG. 2 shows a temporal change of the room temperature during the heating operation. When the on-timer setting means 1 composed of a button, a switch and the like is operated, this output is input to the operation start time determination means 2. When the on-timer set time approaches, the operation start determining means 2
Determines the operation start time according to the room temperature Ta detected by the room temperature sensor 3, and the determined operation start time is input to the on-timer control means 4. The on-timer control means 4 outputs to the air conditioner 15 at the determined operation start time to perform a warm-up operation. The above is the same as the conventional one.

When the input timer set time comes, that is, when the output of the input timer control means 4 is input to the temperature difference detection means 5, the temperature difference detection means 5 detects the room temperature Ta and the room temperature detected by the room temperature sensor 3. Set temperature Ts input from setting means 6
And the temperature difference ΔT is detected. When this temperature difference ΔT is input to the change means 7, the change means 7 changes the operation start time of the air conditioner at the time of the next ON timer operation according to the temperature difference ΔT, and the change result is the operation start time determination means. 2 is input. Table 1 shows the rules stored in the changing means 7.

[0008]

[Table 1]

As shown in Table 1, if the temperature difference ΔT at the set time of the on timer during the cooling operation is 2 deg ° C. or more, the initial value 15 minutes of the warm-up time WTM is extended by 5 minutes, and during the heating operation, the temperature difference ΔT If the temperature is 2 deg. C. or less, the operation start time is changed so that the initial value of the warm-up time WTM of 15 minutes is reduced by 5 minutes. Others are the same.

[0010]

According to the present invention, the operation start time of the next on-timer operation is changed in accordance with the temperature difference between the set temperature and the room temperature at the on-timer set time. Be changed. Therefore, the room temperature at the set time of the next on-timer operation in the on-timer operation can be set to a desired temperature control state regardless of the size and structure of the room to be air-conditioned.

FIG. 1 is a control block diagram of a first embodiment of the present invention.

FIG. 2 is a diagram showing a temporal change of a room temperature in the embodiment.
