[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control device for an air conditioner having a deflecting blade and an indoor fan capable of controlling the direction and flow rate of a blown air flow from an indoor unit.

[0002]

2. Description of the Related Art A conventional control device for an air conditioner of this type will be described. In recent years, for example, a configuration described in an example of Japanese Patent Application Laid-Open No. 6-94219 is known as a technique for making a user feel a change in air flow that is close to natural and improving comfort. The configuration will be described below.

The storage unit of the control unit for controlling the fan motor rotation speed of the indoor unit stores data such that the wind speed of the air flow produced by the air conditioner causes chaotic fluctuations, and the motor rotation speed is calculated based on the data. Change with time.
That is, in order to reproduce the airflow with fluctuations that cause chaotic fluctuations in the room, the rotation speed of the blower drive motor is controlled so that the airflow in the living space undergoes chaotic fluctuations, and the blower is operated based on that, The amount of discharge, that is, the amount of blown airflow, is changed so that the user feels a change in airflow that is close to natural, thereby improving comfort. Further, in the example of Japanese Patent Laid-Open No. 6-74544,
The fan motor rotation speed of the indoor unit or the sway angle of the wind direction plate installed at the air outlet, that is, the angle of the deflection vanes is controlled regardless of the outlet temperature to make the user feel a change in the airflow that is close to natural and improve comfort. It is to try.

[0004]

However, in the above configuration, for example, if the wind direction is always directed to the user by simply controlling the fan motor rotation speed and changing the air flow, the change in the air flow is not enough. Like the natural airflow, the user cannot feel the change when the airflow hits and when it does not. In addition, even if the compressor rotation speed in the outdoor unit is constant, the blowing temperature decreases when the air volume decreases during cooling operation, and conversely, the blowing temperature increases when the air volume increases. There is a case where the user feels a cold blast due to a temperature change, particularly a decrease in the blowing temperature, and gives a user discomfort.

Further, simply changing the wind direction to change the chaos makes the user feel cold blast at a low blowing temperature when the wind direction is high, such as when the load is large and the compressor rotation speed is high, which is very uncomfortable. There was a problem that there is.

In view of the above problems, the present invention makes it possible to chaotically change the wind speed at a predetermined position in the room without causing the user to feel a cold wind during the cooling operation.
The purpose of this is to make the user feel a change in airflow that is close to nature and to improve comfort.

The means is not limited as long as it detects the blowout temperature, such as estimating the blowout temperature from the pipe temperature. The room temperature detecting means 11 is not limited as long as it detects the room temperature, such as estimating the room temperature from the intake temperature of the air conditioner. Further, the temperature setting means 12 is not limited as long as it can set the temperature, such as using a volume or SW. In addition, the temperature difference detecting means 13
The means is not limited as long as it detects a differential temperature, such as using a microcomputer.

The operation of the above arrangement will be described below. The blowout temperature detecting means 1 detects the temperature of the airflow blown out from the indoor unit of the air conditioner 4 by a blowout temperature sensor such as a thermistor, and outputs it as a blowout temperature signal to the deflection speed determining means 3.

The room temperature detecting means 11 detects the temperature of the air sucked into the indoor unit of the air conditioner 4 by a suction temperature sensor such as a thermistor and outputs it as a room temperature signal to the differential temperature detecting means 13.

In the temperature difference detecting means 13, the room temperature detecting means 11 is used.
Based on the room temperature signal and the temperature setting signal which are output values from the temperature setting means 12, for example, a microcomputer calculates a temperature difference between the room temperature and the temperature setting, and the deflection speed is used as a temperature difference signal between the room temperature and the temperature setting.

If the data makes the user feel a change in the air flow that is close to the natural one, such as using a wrestler equation in addition to the Lorentz equation, or using the fluctuation pattern of the natural air flow directly as chaotic data for the deflection speed, that type Is not limited.

In the deflection speed determining means 3, a blowout temperature signal which is an output value from the blowout temperature detecting means 1, the differential temperature detecting means 13 and the deflection velocity chaos data generating means 2,

The wind speed can be chaotically changed at the position, and the user can feel a change in the air flow that is more natural.

Next, the Lorentz equation will be used as an example to describe the details of the deflection velocity chaos data generating means 2. The Lorentz equation is represented by the following differential equation.

Dx / dt = 10y−10x (1.1) dy / dt = −xz + 28x−y (1.2) dz / dt = xy− (8/3) z (1.3) In the above equation, x, y and z are state variables and fall within the following range. Further, t represents continuous time.

The data signals, y and z are values for calculating x.
Equation (1.1) is   dx = (10y-10x) dt (1.4) Next to   x_{n + 1}= X_n+ Dx_n                                      (1.5) Therefore, from equations (1.4) and (1.5),   x_{n + 1}= X_n+ (10y_n-10x_n) Dt (1.6) Becomes y_{n + 1}, Z_{n + 1}Is the same as   y_{n + 1}= Y_n+ (28x_n+ Y_n-X_nz_n) Dt (1.7)   z_{n + 1}= Z_n+ ((-8/8) x_n+ X_ny_n) Dt (1.8) Then, in equations (1.6), (1.7) and (1.8)

Next, the details of the deflection speed determining means 3 will be described with reference to FIG. 3 and Tables 1 and 2. FIG. 3 shows an example of a region in which a user feels uncomfortable due to a feeling of cool air when the air-conditioning apparatus is in a cooling operation and the blowing temperature and the deflection speed are changed to move the deflecting blades up and down by a specified angle. As can be seen from FIG. 3, during the cooling operation of the air conditioner, the user feels uncomfortable due to the feeling of cold wind when the deflection speed is slowed when the blowout temperature is lowered to some extent.

In Table 2, the deflection speed increases in the order of area ,. That is, in consideration of the relationship between the blowing temperature and the deflection speed as shown in FIG. 3, according to Tables 1 and 2, when the blowing temperature is very low in the region, the user does not feel a cold wind for a long time, and The deflection speed is determined fast regardless of the deflection speed chaos data. In the region, the blowing temperature is such that the user does not feel uncomfortable even if the airflow is applied to the user. The wind speed is chaotically changed at a predetermined position in the room without making the user feel, and the deflection speed that allows the user to feel a change in the airflow that is close to natural is determined. Similarly, between the region and the region, the optimum deflection speed for the user is determined according to the blowing temperature. Also, when the temperature difference between the room temperature and the temperature setting is large, for example, when the room has not yet cooled,
Since it is more comfortable for the user to apply a slight air flow, the areas are switched so that the deflection speed becomes slower.

For example, the above 6, 6, 4, 6, 10 ° / sec ... Further, if the deflecting blade is moved vertically from 0 ° to 45 ° downward, the first deflecting blade moves at a deflecting speed of 6 ° / sec.
The blade is lowered from 0 ° to 45 ° and the same deflection speed is 6 °
The blade is controlled to be lifted from 45 ° to 0 ° per second. If this is expressed as a symbol "6 ° / sec: 0 ° → 45 ° → 0 °", from the second time, "" 6 ° / sec: 0 ° → 45 ° →
