Abstract

PURPOSE:To provide a satisfactory feeling of a user by a method wherein an air conditioner is provided with a human body sensor for detecting heat radiated from a human body present within an angle of air blowing to output information of a direction indicating a presence of a person and an air blowing time in each of the air blowing directions is determined under a fuzzy estimation in such a way as air is blown for a relatively long period of time in a region where there are many persons in a plurality of divided air blowing directions on the basis of information. CONSTITUTION:A state in which a blowing fan is fully oscillated to its most right or left position is set as its initial position. At first, under such a condition as above, a micro-computer measures a sum of human detected angular range in each of the air blowing direction zones and a a human body sensing angle range in a full air blowing direction zone and then the most suitable value of a temporary stopping time in each of the air blowing direction zones is determined under a fuzzy estimation. Then, an oscillating movement of the blower fan is carried out in response to the determined controlling amount, and then the fan returns to its initial position, the temporary stopping time is repeatedly determined in reference to a measurement of a human body sensor and the fuzzy estimation.

dt However, if t* is a very small value such as t*<0.5, round it up to t*=0 and use it as the decision controller. This is because the swing angle of a normal electric fan is not so fast, and if it is 0.5 seconds or less, there is not much difference in perceived comfort even if you do not pause.

The initial position is the state in which the blower fan is swung to either the left or right side (Zone ■ or ■ in Figure 3). First, in that state, the microcomputer determines the human body detection angle width of each ventilation direction zone from the detection output of the human body sensor 10. and the total sum T of the human body detection angle widths of all the airflow direction zones, and determine the optimal value t of the pause time for each airflow direction zone by fuzzy reasoning. Then, the swing operation is performed according to the determined control amount, and when the robot returns to the initial position, the determination of the temporary stop time is repeated using human body sensor measurements and fuzzy reasoning. For example, the third
In the example shown in the figure, if the initial position of the swing is zone ■,
Human body detection angle width K of each ventilation direction zone (n=1-61 is K,=10, K2=0, L=20.K,=0,K
5=30, K6-0, and ■=60. In this case, the inference results for each air blowing direction zone t (n = 1 to 61 are: t1 = 1, 5 seconds, t, = 0 seconds, t3 =
2 seconds, t4 = 0 seconds, ts'' 2.6 seconds, ta = 0 seconds.In other words, it stops for 15 seconds in the initial position zone, passes through zone ■, stops for 2 seconds in zone ■, and then stops in zone ■. It passes through zone ■, stops for 26 seconds in zone ■, stops for another 2.6 seconds in zone ■ without going to zone ■, passes through zone ■, stops in zone ■ for 2 seconds, passes through zone ■. , stop in zone ■ for 1.5 seconds to complete one cycle. Then,
The human body sensor 10 detects and measures the body again, and performs a swinging motion according to the inference result.

In this way, the oscillation motion of the fan takes into account the weight of the number of people in each zone relative to the number of people in the zone in all directions of the fan, and controls the pause time of each zone. That is, in a zone where there are no people, it can pass or cancel, and in a zone where there are people, it can be temporarily stopped for a time corresponding to the weight of the number of people in relation to the total number of people.

Although this embodiment specifically describes an example in which the present invention is applied to an electric fan, similar effects can be obtained when applied to an air conditioner with an automatic variable blower mechanism, such as an air conditioner with a swing louver.

In addition, in the above embodiment, six airflow direction zones in 30 degree increments have been explained, but if the mechanical performance of the air conditioner body allows, it is possible to create airflow direction zones over a wider swing angle range and in finer angle increments. The present invention can be applied to such cases.

Furthermore, in the above embodiment, a total of 6 control rules are created using four types of fuzzy labels related to the human body detection angle width of each airflow direction zone and 4 fl fuzzy labels related to the sum of human body detection angle widths of all airflow direction zones. However, if the detection accuracy of the human body sensor is not very good, it is necessary to increase the number of control laws. The number of control laws and the number of fuzzy labels are preferably set based on the accuracy of the human body sensor and the number of zones in the air blowing direction (control resolution) of the air conditioner.

In the above embodiment, the software of the microcomputer of the control unit 11 controls the control amount from MIN to MAX to every one period of swing.
Although a so-called real-time inference method is shown in which calculation is performed using the centroid inference method, the present invention also applies to a so-called look-up method in which the control amount for the sensor human input value is calculated in advance using fuzzy inference and written to the ROM memory of a microcomputer. You can achieve a similar effect by implementing

As is clear from the above explanation, the air conditioner according to the present invention is an air conditioner equipped with an air blowing mechanism in which the air blowing direction is variable. It is equipped with a human body sensor that detects and outputs information on the direction in which a person is present, and based on the information, air is blown for a relatively long time in the section where there are many people among the plurality of air blowing direction sections. , the air blowing time in each air blowing direction segment is determined by fuzzy reasoning, that is, the air blowing motion of the air conditioner is
The pause time for each ventilation zone is controlled by considering the weight of the number of people in each ventilation zone relative to the number of people in the zones in all directions of the air conditioner, so there are no people present. Pass or cancel in the zone,
In a space where there are people, it is possible to pause for a time corresponding to the weight of the number of people in relation to the total number of people.

Therefore, when a plurality of people are trying to feel comfortable using one air conditioner, it is possible to control the automatic direction variable air blowing operation in a very well-balanced manner.
