A room temperature signal is transmitted from the air conditioner to the receiving circuit 209, and the air conditioner is operated in a manner that is comfortable for the human body based on the room temperature near the human body.

Problems to be Solved by the Invention However, in the conventional configuration, it is difficult to determine whether a human body is present or absent,
- The sensor that detects and transmits the room temperature signal for operation control is the remote control room temperature sensor 203 or the main body room temperature sensor 207.
For example, if you are in heating operation, you would want to lower the heating when you are moving indoors than when you are sitting, and even if there are people in the room, depending on the amount of activity. , Despite the required set temperatures being different, there was a problem in the past that it was not possible to deal with these.

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, it is an object of the present invention to provide an air conditioner control device that can change the set temperature according to the amount of human activity and perform comfortable air conditioning.

Means for Solving the Problems In order to achieve the above object, the air conditioner control device of the present invention includes a temperature sensor for detecting room temperature, a temperature setting device for setting the air conditioning temperature, and a temperature sensor for controlling the indoor temperature into a plurality of zones. zone dividing means for dividing the zone into two zones, zone determining means for determining each divided zone, human body detecting means for detecting a human body in the room;
human body activity amount determination means for determining the amount of human body activity based on signal outputs from the human body detection means and the zone determination means; and temperature setter set by the temperature setting device based on the signal output from the human body activity amount determination means. This configuration includes a set temperature changing means for changing the air conditioning temperature.

According to the above-described configuration, the present invention uses the zone determining means to determine in which zone divided by the zone dividing means the human body detected by the human body detecting means is located, and determines the amount of human body activity based on the transition of the zone in which the human body is detected. The amount of human body activity is determined by the means, and if the amount of human body activity is large, the set air conditioning temperature is changed to a lower value using the set temperature changing means, and if the amount of human body activity is small, it is changed to a higher value to make it more Provides comfortable air conditioning.

EXAMPLE Hereinafter, an example of the present invention will be explained with reference to the drawings regarding air conditioning.

FIG. 1 is a block diagram showing an embodiment of the present invention.
FIG. 2 is a diagram showing a situation in which an air conditioner is actually installed in a room. 1 is an indoor unit of the air conditioner, and 2 is a control device for the air conditioner. The air conditioner control device 2 includes a temperature detector 3 that detects the room temperature, a temperature setting device 4 that sets the air conditioning temperature, a zone dividing means 5 that divides the room into a plurality of zones, and a zone divider 5 that divides the room into a plurality of zones. Zone determining means 6 for determining
, a human body detection means 7 for detecting a human body in the room, and a human body activity amount determination means 8 for determining the amount of human body activity based on signal outputs from the human body detection means and the zone determination means;
and a set temperature changing means 9 for changing the air conditioning temperature set by the temperature setting device based on the signal output from the human body activity amount determining means. The lower surface of the indoor unit 1 of the air conditioner is open on the same plane as the ceiling 10. Room 1
1 is composed of the ceiling 10, side walls 12, 13, 14, windows 15, and floor 16. The zone dividing means 5 'lay' the floor 16! b*'/Qt'
Divide into each zone p' d.

Next, the operation of the air conditioner control device configured as described above will be explained using the flowchart of FIG. 3 and the timing chart of FIG. 4. The air conditioning temperature is set using the temperature setting device 4. Further, the zone dividing means 5

yd into each zone. Hereinafter, the operation will be performed according to the procedure of the flowchart shown in FIG.

In step 101, the human body detection means 7 checks whether a person is present in the room, and if so, step 102
Then, the zone determining means 6 determines in which zone the human body is detected. In step 103, the signal outputs from the human body detection means 7 and the zone determination means 6 are input to the human body activity amount determination means 8. Steps 101 to 103 are repeated at intervals of several seconds. (Step 1
04) In steps 105 to 107, the amount of human activity is determined by the human body activity amount determining means 8, and in steps 108 to 110, if the amount of activity is large,
The set temperature changing means 9 changes the air conditioning temperature to a lower value, and if the temperature is lower, it is changed to a higher value.

Step 111) Regarding the above operation, an example of human body detection according to an embodiment of the present invention is shown in the timing chart of FIG. 4 for each zone.

In FIG. 4(a), the frequency of human body detection in each zone is high, and it can be said that there is a large amount of activity, so the air conditioning is performed at a temperature lower than the set temperature. On the other hand, in FIG. 4(b), the frequency of human body detection in each zone is low, and it can be said that the amount of activity is low, so the air conditioning is performed at a temperature higher than the set temperature.

According to the configuration of the above embodiment, the human body activity amount determining means 8 changes the set temperature according to the amount of human activity, so when the amount of activity is large, the set temperature is lowered to provide more comfortable air conditioning. When the amount of activity is low, the set temperature can be set higher to save energy.

Additionally, if no human body is detected for a certain period of time, the air conditioner can be turned down to save energy.

Incidentally, in the above embodiments, cooling was explained, but the same thing can be said about heating.

More than the effects of the invention, as is clear from the examples, the present invention uses a zone determining means to determine in which zone divided by the zone dividing means the human body detected by the human body detecting means is located, and changes in the zone in which the human body is detected. Based on this, the amount of human body activity is determined by the human body activity amount determining means, and if the amount of human body activity is large, the set air conditioning temperature is changed to a lower value by the set temperature changing means, and if the amount of human body activity is small, Since it is configured to change to a higher temperature, more comfortable and energy-saving air conditioning can be achieved.
