Embodiment 1 Hereinafter, a first embodiment of the present invention will be described with reference to FIG.
This will be described with reference to FIG. FIG. 1 is a schematic block diagram of a control device for an air conditioner according to a first embodiment of the present invention. In FIG. 1, 1 is an operation mode storage unit, 2 is a temperature distribution detecting unit, 3 is a human body position detecting unit, 4 is a wind direction determining unit, 5 is a wind direction control signal generating unit, and 6 is an air conditioner.

Here, the temperature distribution detecting means 2 detects the temperature distribution near the human body, for example, by calculating the temperature distribution near the human body from the air volume, wind direction, blowing temperature, room temperature, the position of the human body, etc. of the air conditioner 6. The means is not limited as long as it is capable of detecting. Further, the human body position detecting means 3 is a detecting means capable of detecting the human body position, for example, detecting the human body position by performing image processing on infrared image information obtained using an infrared sensor or the like, The detecting means is not limited.

The operation of the above configuration will be described below. Here, as an example, an embodiment of an air conditioner having blow-off means capable of blowing at two locations will be described. The number is not limited as long as it is a blowing means capable of blowing at two or more locations.

The operation mode storage means 1 stores operation modes such as cooling and heating, and outputs the operation modes to the wind direction determination means 4 as operation mode storage signals.

The temperature distribution detecting means 2 uses the detected temperature distribution near the human body as a temperature distribution signal to the wind direction determining means 4 such that the temperature near the upper body of the human body is the upper temperature and the temperature near the feet is the lower temperature. Output.

The human body position detecting means 3 is 1 m to the left and 2 m to the depth when viewed from the air conditioner 6, and the distance to the human body is calculated to be 2.236 m. And the distance is output to the wind direction determining means 4 as a human body position signal.

The wind direction determining means 4 determines the upper temperature of the human body from the operating mode storing signal, the temperature distribution signal and the human body position signal output from the operating mode storing means 1, the temperature distribution detecting means 2 and the human body position detecting means 3. Each of the wind directions blown by the blowing means is determined so that the lower temperature of the human body is fixed at a certain value higher than the upper temperature, and is output to the wind direction control signal generating means 5 as a wind direction signal. .

The wind direction control signal generating means 5 generates a wind direction control signal for controlling the wind direction of the air conditioner 6, and outputs the generated signal to the air conditioner 6.

In the air conditioner 6, the upper and lower temperatures are maintained at the upper and lower set temperatures, respectively, by automatically controlling each wind direction blown by the blower means based on the wind direction control signal. be able to. The operation mode in which the air conditioner 6 operates is output to the operation mode storage unit 1 as an operation mode signal.

Next, the details of the wind direction determining means 4 will be described with reference to FIG. In FIG. 2, the vertical axis is the set temperature, the horizontal axis is time, Ts1 is the upper set temperature, and Ts2 is the lower set decision. The operation of the above configuration will be described below.

First, the upper set temperature Ts1 is changed near a set temperature set by the user.
1 / f fluctuation or random change, which stimulates a user's skin temperature receptor comfortably and activates physiological functions and cerebrum, and is determined in advance by experiments or the like.

If the lower set temperature Ts2 is determined by the set temperature set by the user as shown in (Table 1), or if the set temperature of the user cannot be set, such as in automatic operation, for example, the lower set temperature Ts2 is set to "lower set temperature". If the upper temperature of the human body changes, by keeping this lower temperature, a value that does not feel cold even when the upper temperature falls,
It is determined in advance by experiments or the like.

[0025]

[Table 1]

The temperatures near the human body, such as the upper temperature and the lower temperature, are determined by the blowing temperature, air volume, wind direction, room temperature, human body position, and the like. The blowout temperature and air volume do not change so much as to affect the temperature distribution near the human body when the room temperature is stabilized. That is, the temperature distribution near the human body is
Significantly affected by wind direction and body position. For example, assuming that the room temperature during the heating operation is stable, the blowing temperature is 40 ° C., and the air volume is weak, if the wind direction is in the direction of the human body position, the temperature near the human body is as shown in Table 2 for each distance to the human body.

[0027]

[Table 2]

On the other hand, when the wind direction is different from the human body position direction,
Since the influence of the temperature of the blown air flow is smaller than that in the direction of the human body position, the temperature is lower, as shown in (Table 3).

[0029]

[Table 3]

As described above, since the blowing temperature during heating is higher than the room temperature, the temperature near the human body increases when the wind direction is directed to the human body position, and the temperature near the human body decreases when the wind direction is directed to a position other than the human body position. . On the other hand, during cooling, the temperature is opposite to that during heating. The temperature near the human body decreases when the wind direction is directed to the human body position, and the temperature near the human body increases when the wind direction is directed to a position other than the human body position.

The wind direction determining means 4 uses the operation mode storage signal and the temperature distribution signal for each sampling time.
Based on (Table 4) and (Table 5), it is determined whether the wind direction is the direction of the human body position.

[0032]

[Table 4]

[0033]

[Table 5]

The result of this determination and the human body position signal, that is,
From the left-right direction, the depth direction, and the distance viewed from the air conditioner 6, in the case of the human body position direction, in the direction of the human body position signal,
In cases other than the human body position, the wind direction is determined based on (Table 6) and (Table 7) so as to avoid the human body position in the left-right direction.

[0035]

[Table 6]

[0036]

[Table 7]

These are output as wind direction signals to a wind direction control signal generating means 5 for generating a signal for controlling the wind direction of the air conditioner 6.

That is, for each sampling time, for example, the operation mode signal output from the operation mode storage means 1 is heating, the upper temperature T1 of the temperature distribution signal output from the temperature distribution detection means 2 is 25.degree. T2 to 26
° C, the upper set temperature Ts1 is 24 ° C, the lower set temperature Ts2 is 27 ° C, the human body position signal is 1 m to the left and 2 in the depth direction.
Assuming that m and the distance to the human body position are 2.236 m, one of the blowing means capable of blowing at two locations, which controls the upper temperature, is other than the human body position according to (Table 4). That is, the wind direction is determined to be 2 m to the right and 2 m to the depth based on (Table 6). The other for controlling the lower temperature is the human body position according to (Table 5). That is, the wind direction is determined to be 1 m left and 2 m depth, and these are output as wind direction signals to the wind direction control signal generation means 5 ". In the above embodiment, when determining the wind direction in a direction other than the human body position, the human body position is avoided in the left-right direction.
The direction is not limited as long as the direction avoids the position of the human body.

As described above, according to the first embodiment, in the air conditioner 6 which can blow air into at least two places, the operation mode storage means 1, the temperature distribution detection means 2, and the human body position detection means Based on the operation mode storage signal, the temperature distribution signal, and the human body position signal output from 3, the wind direction determining means 4 changes the upper temperature of the human body within a predetermined temperature range, and the lower temperature of the human body, that is, the temperature of the feet, is the upper temperature. The wind direction is determined so as to be fixed at a certain higher value, and is output to the wind direction control signal generating means 5 as a wind direction signal. Based on this, the wind direction of the air conditioner 6 is automatically controlled, so that the air direction is always near the user. By grasping the temperature distribution and position of the user, a temperature change is given only to the upper part of the user, and the feet can always be kept warm. Therefore, it is possible to make the user surely feel the stimulus caused by the temperature change, eliminate the insensitivity to the feeling of heat and air conditioning, activate the physiological functions and the cerebrum, and always feel the cold without feeling cold. A refreshing sensation with a pleasant stimulus can be given, and the comfort can be improved.

(Embodiment 2) Next, a second embodiment of the present invention will be described with reference to FIG. Here, the same components as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted. In FIG. 3, reference numeral 7 denotes an air volume determining unit, and 8 denotes an air volume control signal generating unit. In the above configuration,
The operation will be described below.

In the air volume determining means 7, the human body position detecting means 3
Based on the human body position signal output from, the air volume is determined so as to reduce the sense of airflow, and is output to the air volume control signal generating means 8 as an air volume signal.

The air volume control signal generating means 8 generates an air volume control signal for controlling the air volume of the air conditioner 6 and outputs it to the air conditioner 6.

In the air conditioner 6, by automatically controlling the air volume based on the air volume control signal, it is possible to maintain the air volume that alleviates the sense of airflow.

Next, details of the air volume determining means 7 will be described. The air volume determination means 7 reduces the feeling of airflow based on the distance of the human body position signal as shown in (Table 8).
The air volume is determined in advance by experiments or the like so that the air volume is reduced as the distance is shorter.

[0045]

[Table 8]

As described above, according to the second embodiment, based on the human body position signal output from the human body position detecting means 3 to the air flow determining means 7, the air flow determining means 7 reduces the air flow to reduce the sense of airflow. Is determined and output to the air volume control signal generating means 8 as an air volume signal.
By automatically controlling the air volume of the air, the temperature distribution and position near the human body are always grasped, and the temperature change is given only to the upper part of the human body while preventing the difference in the temperature sensation due to the influence of the airflow. Can be held. Therefore,
Makes the user feel the stimulus caused by the temperature change more reliably, eliminates the familiarity with the thermal sensation and the insensitivity to air conditioning, activates the physiology and cerebrum, and has a pleasant stimulus without feeling cold. An exhilarating feeling can be given, and the comfort can be further improved.

(Embodiment 3) Next, a third embodiment of the present invention will be described with reference to FIG. Here, the same components as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted. In FIG. 4, 9 is a comfort level distribution detecting means, 1
0 is a wind direction determining means, and 11 is a wind direction control signal generating means. The operation of the above configuration will be described below.

Here, the comfort level distribution detecting means 9 will be described. For example, as for the temperature, the temperature distribution near the human body is detected as in the first embodiment, the humidity is detected by a humidity sensor or the like, the radiation temperature is detected by a radiation sensor or the like, and the activity amount is detected. The amount of clothing is determined by the outside air temperature, and the amount of clothing is determined based on the outside air temperature. For example, the degree of comfort is calculated from the six parameters of temperature, humidity, airflow, radiation, amount of activity, and amount of clothing obtained as described below.

By normalizing the normal comfort calculation formula calculated from the six parameters of temperature, humidity, airflow, radiation temperature, activity amount, and clothing amount, the comfort level can be calculated by the two parameters of temperature and radiation temperature. Be able to calculate. That is, a reference point at which the comfort level becomes 0, for example, temperature: 24
° C, humidity: 50%, radiation temperature: 24 ° C, activity: 1.0
The reference value other than the temperature is fixed at the reference point where met, the amount of clothing: 1.0clo and the airflow that is the above-mentioned constant value: 0.2 m / s, and the temperature is, for example, 20 ° C, 24 ° C, 28 ° C.
When the approximate comfort calculation formula determined only by the temperature is obtained from the comfort obtained by changing the temperature to 32 ° C., the comfort (temperature) = 3 × (0.060 × temperature−0.436) −3.

Similarly, the reference values other than the radiation temperature are fixed, and the radiation temperature is set to, for example, 20 ° C., 24 ° C., 28 ° C.,
When the approximate comfort formula that is determined only by the radiation temperature from the comfort level obtained by changing to 2 ° C is obtained, the comfort level (radiation temperature) = 3 x (0.037 x radiation temperature + 0.099) -3 . Therefore, a simplified comfort level calculation formula that is standardized and can calculate the comfort level using two parameters of temperature and radiation temperature is expressed by the following equation.

Comfort (temperature, radiation temperature) = 3 × (0.060 ×
Temperature-0.436) x (0.037 x radiant temperature + 0.099) -3 In this simplified comfort formula, the upper and lower temperatures near the human body are used for temperature, and the detected radiant temperature is used for radiant temperature. Further, by adding correction values for humidity, activity amount, and clothing amount excluding airflow that is not a constant value, a comfort level distribution can be calculated by the following equation.

Comfort = 3 × (0.060 × Temperature−0.436) × (0.03
7 x radiation temperature + 0.099) -3 + humidity correction value + activity amount correction value + clothing amount correction value Here, the humidity correction value is determined based on the humidity, based on experiments, comfort equation, etc. in advance. The humidity correction value is determined from, for example, the table of (Table 9) in which the humidity correction value is determined.

[0053]

[Table 9]

The activity amount correction value is determined based on the activity amount.
The activity amount correction value is determined from, for example, a table of (Table 10) in which the activity amount correction value is determined based on an experiment, a comfort level calculation formula, or the like in advance.

[0055]

[Table 10]

The clothing amount correction value is determined based on the outside air temperature.
The clothing amount correction value is determined from, for example, the table of (Table 11) in which the clothing amount correction value is determined based on an experiment, a comfort level calculation formula, or the like in advance.

[0057]

[Table 11]

Now, for example, temperature: 23 ° C., humidity: 40
%, Radiation temperature: 21 ° C, activity: standard, outside temperature: 10 ° C
Then, the comfort level is: comfort level = 3 x (0.060 x 23-0.436) x (0.037 x 21 + 0.099)
-3 + 0.00 + 0.10 + 0.00 = -0.419.

In the above embodiment, the comfort expression was simplified by normalization so that it could be calculated using two parameters, temperature and radiation temperature. However, four values excluding temperature and radiation temperature were included in the comfort expression. Even if the comfort distribution is calculated or directly detected by other approximation methods such as substituting, the method is not limited as long as the comfort distribution is detected.

The comfort distribution detecting means 9 converts the detected comfort distribution in the vicinity of the human body into a comfort distribution such that the comfort near the upper body of the human body is defined as the upper comfort, and the comfort near the feet is defined as the lower comfort. The signal is output to the wind direction determining means 10 as a signal.

The wind direction determining means 10 includes the driving mode storage means 1, the comfort level distribution detecting means 9, and the human body position detecting means 3.
From the driving mode storage signal, the comfort distribution signal and the human body position signal output from the human body, the upper comfort of the human body is changed within a predetermined comfort range, and the lower comfort of the human body is at a certain value higher than the upper comfort. Each of the wind directions blown by the blowing means is determined so as to be fixed, and is output to the wind direction control signal generating means 11 as a wind direction signal.

The wind direction control signal generating means 11 generates a wind direction control signal for controlling the wind direction of the air conditioner 6, and outputs the generated signal to the air conditioner 6.

In the air conditioner 6, the upper and lower comfort levels are controlled by automatically controlling each wind direction blown by the blowing means based on the wind direction control signal.
Upper and lower set comfort levels can be maintained respectively.

Next, the details of the wind direction determining means 10 will be described with reference to FIG. In FIG. 5, the vertical axis is the set comfort level,
The horizontal axis is time, Ps1 is the upper set comfort level, and Ps2 is the lower set comfort level. The operation of the above configuration will be described below. First, the upper set comfort level Ps1 is changed in the vicinity of the set comfort level set by the user. This change is, for example, 1 / f fluctuation or random change, and comfortably stimulates the temperature receptor on the skin of the user. It activates physiological functions and the cerebrum, and is determined in advance by experiments and the like.

The lower set comfort level Ps2 is determined by the set comfort level set by the user as shown in (Table 12).
If the user's set comfort cannot be set, such as in automatic driving, the lower comfort is maintained even if the upper comfort of the human body changes, for example, “lower set comfort is +0.2”. By doing so, a value that does not cause a feeling of cold even when the upper comfort level falls is determined in advance by experiments or the like.

[0066]

[Table 12]

The comforts near the human body, such as the upper comfort level and the lower comfort level, include the blow-off temperature, the air volume, the wind direction, and the like.
It is determined by the room temperature and the position of the human body. When the comfort level is stabilized, the blowout temperature and air volume do not change so much as to affect the comfort level distribution near the human body. That is, the comfort distribution near the human body is greatly affected by the wind direction and the human body position. For example, assuming that the comfort level during the heating operation is stable, the blowing temperature is 40 ° C., and the air volume is weak, when the wind direction is the direction of the human body, the comfort level near the human body is different according to the distance to the human body as shown in Table 13. Become.

[0068]

[Table 13]

On the other hand, when the wind direction is different from the human body position direction,
Since the influence of the temperature of the blown airflow is smaller than in the direction of the human body position, the temperature is lower, as shown in (Table 14).

[0070]

[Table 14]

As described above, since the blowing temperature during heating is higher than the room temperature, the comfort level near the human body increases when the wind direction is directed to the human body position, and the comfort level near the human body increases when the wind direction is directed to a position other than the human body position. Lower. On the other hand, during cooling, it is the opposite of heating, and when the wind direction is directed to the human body position, the comfort level near the human body decreases, and when the wind direction is directed to a position other than the human body position, the comfort level near the human body increases.

The wind direction determining means 10 determines, at each sampling time, whether or not the wind direction is the direction of the human body position based on the driving mode storage signal and the comfort distribution signal based on (Table 15) and (Table 16).

[0073]

[Table 15]

[0074]

[Table 16]

The result of this determination and the human body position signal, that is,
From the left-right direction, the depth direction, and the distance viewed from the air conditioner 6, in the case of the human body position direction, in the direction of the human body position signal,
In cases other than the human body position, the wind direction is determined based on (Table 17) and (Table 18) so as to avoid the human body position in the left-right direction.

[0076]

A wind direction control signal generating means 11 for generating a signal for controlling the wind direction of the air conditioner 6 using these as wind direction signals.
Output to

That is, for each sampling time, for example, the operation mode signal output from the operation mode storage means 1 is heating, and the upper comfort level of the comfort distribution signal output from the comfort distribution detection means 9 is +0.00. , Lower temperature +
0.10, the upper set comfort level is -0.50, the lower set comfort level is +0.50, the human body position signal is 1 m to the left, 2 m in the depth direction, and the distance to the human body position is 2.236 m. One of the blow-off means capable of controlling the upper comfort level among the blow-off means that can be blown into different places is other than the human body position according to (Table 15). That is, the wind direction is determined to be a direction of 2 m to the right and a depth of 2 m. The other for controlling the lower temperature is a human body position according to (Table 16). That is, the wind direction is determined to be 1 m left and 2 m deep, and these are output as wind direction signals to the wind direction control signal generation means 11 ". In the above embodiment, when determining the wind direction in a direction other than the human body position, the human body position is avoided in the left-right direction, but the direction is not limited as long as the direction avoids the human body position.

As described above, according to the third embodiment, in the air conditioner 6 capable of blowing at least two places, the operation mode storage means 1, the comfort level detection means 9, and the human body position detection Based on the driving mode storage signal, the comfort distribution signal and the human body position signal output from the means 3, the wind direction determining means 10 changes the upper comfort of the human body within a predetermined comfort range, and furthermore, the lower comfort of the human body, The wind direction is determined so that the foot comfort level is fixed at a certain value higher than the upper comfort level, and is output to the wind direction control signal generating means 11 as a wind direction signal, based on which the wind direction of the air conditioner 6 is automatically controlled. Thereby, the comfort distribution and the position near the user are always grasped, the comfort is changed only in the upper part of the user, and the feet can always be kept warm. Therefore, it is possible to make the user surely feel the stimulus due to the change in the degree of comfort, eliminate the insensitivity to the adaptation of the thermal sensation and the air conditioning, activate the physiological functions and the cerebrum, and without feeling the cold, A refreshing feeling with a pleasant stimulus is always given, and the comfort can be improved in consideration of the temperature, humidity, air current, radiation, amount of activity and amount of clothes.
