Abstract

PURPOSE:To enable to obtain a comfortable condition of a room temperature, by performing temperature control so that a setting value of the room temperature is made to coincide with a rhythm of a living body of a human being by a microcomputer. CONSTITUTION:A rhythm of a living body peculiar to a human being on a day cycle is formed by the human being by varying hourly the body heat, consumption of oxygen, a number of breaths, blood pressure, the pulse rate and secretion of a hormone. A room temperature is set at a low level at the time when activity of the living body of the human being is active and is set at a high level when it becomes a recess and bedtime as shown by a chart B. Then, time is set by applying the time from the outside to an input circuit 2 of a controller 1 and a setting value of the room temperature corresponding to the time is set according to a program of a memory 4. Then, an operation control signal of an air conditioner is signaled from an output circuit 5 and the air conditioner is operated so that the room temperature arrives at a setting value by comparing the room temperature to be applied to the input circuit 2 with the above mentioned setting value through sensing of room temperature in a CPU3.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an air conditioner that can automatically change the temperature setting of an air conditioned space in accordance with human biological rhythm.

Conventionally, temperature settings in air conditioners have been carried out by simply keeping the set temperature TS constant at the temperature selected by the user, as shown in Figure 1A, or by changing the outside temperature TO, as shown in Figure 1B.
Various methods have been applied, such as a method that incorporates outside temperature compensation control in consideration of the difference in temperature and indoor temperature, and a method that performs room temperature control for sleep operation during bedtime TA, as shown in Figure 1C. Ta.

That is, in FIG. 1A, the user sets the set temperature TS.
By selecting , the room temperature will always be kept constant. Also,
In Figure 1B, when the outside temperature rises from the room temperature initially set at TSI to the TOI, the air conditioner detects this and gradually slides the room temperature setting, so that the outside temperature reaches TSI.
When the temperature becomes O2, the room temperature is set to TS2.

Conversely, when the outside temperature drops, the room temperature setting is controlled to be lowered.

In addition, in the case of Figure 1 C, by switching the operation of the air conditioner to sleep mode during bedtime TA, the room temperature can be adjusted to TS.
It is controlled to gradually increase from I and maintain it at TS3.

In this way, conventional temperature control does not necessarily match the level of biological activity of humans. There were drawbacks such as feeling chilly in the early morning.

This invention was made in order to eliminate the above-mentioned drawbacks of the conventional technology, and it is possible to obtain comfortable room temperature conditions by controlling the temperature using a microcomputer so that the x temperature setting value matches the human biological rhythm. The purpose is to provide air conditioners.

Embodiments of the air conditioner of the present invention will be described below based on the drawings. FIG. 2A is a diagram showing changes in human biological activity (biological rhythm) during one day.

As shown in Figure 2 A, a person's body temperature, oxygen consumption,
Breathing rate, blood pressure, pulse rate, hormone secretion, etc. change from moment to moment, forming a unique human biological rhythm that cycles through the day.

For this reason, even under the same temperature, humidity, and airflow conditions, the body will experience different sensibilities depending on the time of day. For example, biological activity is most active for 2 to 3 hours after lunch.
Due to the large amount of energy metabolism, the body temperature is high (and sweating is also common), so unless you set the room temperature low, you will feel hot.

On the other hand, late at night and early in the morning, when human vitality is at its weakest, if the room temperature is not high, people will feel chilly (feeling uncomfortable).

The present invention has been made with attention to this point, and it is an object of the present invention to obtain an air conditioner in which a temperature setting program corresponding to the human biological rhythm as described above is incorporated into the temperature control device of the air conditioner. Figure 2B shows an example of room temperature settings that change depending on time.

In other words, in FIG. 2B, the room temperature is set low when the human's biological activity is active, and set high when the human body's activity is attenuated and it is time to rest or go to bed.

As described above, the means for changing the set value depending on the time in response to the biological rhythm can be realized easily and inexpensively by using a microcomputer and controlling the program. FIG. 3 shows a conceptual diagram of a control device using a microcomputer.

In FIG. 3, 2 is an input circuit, 3 is a CPU, 4 is a memory, and 5 is an output circuit, and these constitute a control device I, and the room temperature setting value that is changed according to one time is different. It is first programmed into memory 4.

As for the operation of the control device 1, first, the time is set by externally inputting the time to the input circuit 2, and the room temperature setting value corresponding to that time is set according to the program in the memory 4.

Next, the CPU 3 detects the room temperature and compares the room temperature input to the input circuit 2 with the set value, and an operation control signal for the air conditioner is transmitted from the output circuit 5, and the room temperature is set to the set value. The air conditioner is operated to reach .

When the clock in the control device 1 advances the time.

A new room temperature setting value appropriate for that time is set, and the above operation is repeated.

As described above, according to the air conditioner of the present invention, the set value of the room temperature is changed over time in accordance with the human biological rhythm, so it is possible to control the room temperature in accordance with the biological activities of each human being, making it comfortable. It is possible to realize air conditioning.
