[Detailed description of the invention]

[Industrial Field of Application] The present invention relates to an air conditioner control device, and particularly to control of the blowing direction of the air conditioner.

[Prior Art] In conventional air conditioners, it was common to manually adjust the direction of the air blown out from a fan built into the indoor unit using flaps or louvers vertically or horizontally. . In addition, some methods include attaching a servo motor to the flap to automatically change the wind direction up or down when switching between heating and cooling, or using a screw-type method in the louver to periodically change the wind direction. .

[Problems to be solved by the invention] Since conventional air conditioners are configured as described above, it is possible to manually change the wind direction, automatically change the wind direction only when switching between cooling and heating, or simply change the wind direction. They only automatically changed the direction of the wind so that it was evenly distributed over the entire surface, but did not make fine-grained automatic adjustments to the wind direction. Therefore, for example, when there is a large temperature difference between the room temperature and the set room temperature, such as when starting air conditioning or heating, more cold or warm air is sent to areas where people are present, and when the temperature difference becomes smaller, the air is sent evenly throughout the area. The problem was that it could not meet the detailed demands of users.

The present invention has been made to solve the above problems, and an object of the present invention is to provide an air conditioner control device that can finely adjust the direction of air blowing from an indoor unit of an air conditioner.

[Means for Solving the Problems] An air conditioner control device according to the present invention includes a wind direction changing means for periodically changing the blowing air direction;
A means for dividing the direction of the blowing air into a predetermined number of directions, a means for instructing and setting a specific section among the directions, a means for detecting a temperature difference between the set room temperature and the current room temperature, and a means for detecting the temperature difference between the set room temperature and the current room temperature, The means for changing the wind direction is controlled so that the longer the blowing wind direction is, the longer the time that the blowing wind direction is in the specific section is increased, and the time that the blowing wind direction is outside the specific section is gradually decreased as the section moves away from the specific section. It is equipped with a wind direction change control means.

[Function] In this invention, for example, if a section facing a place where people are present is designated as a specific section, when the temperature difference between the set room temperature and the room temperature is large, such as when starting air conditioning, the blowing air will be directed to that specific section. Control is performed so that the time the vehicle is facing a specific section is lengthened, and when the temperature difference becomes smaller, the time the vehicle is facing a specific section is shortened. In this way, when the temperature difference is large, more air is sent especially to areas where people are present, and when the temperature difference is small, the air is sent evenly to all rooms, and fine-grained control is automatically performed.

[Examples] Examples of the present invention will be described below with reference to the drawings.

It consists of a circuit 7, a display 11, and an output circuit 16 that outputs control signals to the indoor fan 2 and other devices. 17 is a setting switch provided on the remote control unit 8 for setting a specific section, which will be described later; 18 is a room temperature sensor that detects the room temperature Tr; 19 is a room temperature setting device that sets the room temperature to To; 20 is divided into 8 sections a to h. A specific section setting means for specifying and setting a specific section among the blowout directions 4, which is configured to send a signal from the remote controller 9 to specify a specific section among a to h by opening and closing the setting switch 17 by the user. The data is transmitted, passed through the receiving circuit 10, inputted to the microcomputer 12, and stored and set at a predetermined address in the memory 15. 21 is a temperature difference detection means;
The temperature difference To-Tr between the set room temperature To and the current room temperature Tr is calculated and detected in the microcomputer 12 from the temperature signal input from the room temperature sensor 18 and the room temperature setting device 19 to the microcomputer 12 via the remote control 9 receiving circuit 10. do. Reference numeral 22 denotes a wind direction changing means which controls the wind direction changing means 5 so as to make the time in a specific section where the blowing wind direction 4 is set longer than in other sections according to the temperature difference detected by the temperature difference detecting means 21, which is controlled by a microcomputer. 12.

Next, the operation will be explained with reference to FIGS. 3, 4, and 5. Figure 3 shows the memory 15 of the microcomputer 12.
FIG. 4 is a flowchart showing a program for wind direction change control stored in the wind direction change control program. The time the louver 3 stops and the temperature difference between the set temperature To and the current room temperature Tr
A diagram showing the relationship between To and Tr, Figure 5 is 8 sections a to
This is a diagram showing the relationship between the rotation distance from a specific section set within h to another section and the ratio of the time the louver 3 stops in that section to the stop time in the specific section (stop time ratio). , the stop time ratio is made smaller as the distance from the specific section increases. It is assumed that the relationships shown in FIGS. 4 and 5 are stored in the memory 15 in advance.

First, when signals of the current room temperature Tr, set room temperature To, and specific section setting are transmitted from the remote controller 9, they are received in step (30). The received data is stored in the memory 15 of the microcomputer 12. In step (31), select a specific section setting signal from this data,
The CPU 14 displays the set section on the display 11 through the output circuit 15. Next, in step (32), the temperature difference To-Tr between the room temperature data and the set temperature data is calculated, and in step (33), the louver stop time in a specific section having the relationship shown in FIG. 4 is calculated from this temperature difference. Further steps (34)
Then, by knowing which section from a to h the direction in which the louver 3 is currently facing, that is, the blowing air direction 4, is located, the rotation distance from the specific section can be obtained, and from this and the relationship shown in Fig. 5. The stop time ratio in that section is determined, and a calculation process is performed in which the value obtained by multiplying this by the louver stop time in the specific section obtained in step (32) is determined as the stop time in this section. Next, in step (35), the time during which the louver 3 has stopped at the current position is compared with the time calculated in step (34), and if the calculated time has been exceeded, step (36) is performed. Proceed to move the louver 4.
If not, proceed to step (37) and move to Louver 4.
A control signal is output to the drive circuit 7 to keep it stopped. Repeat the above operation until Louver 1
4, that is, the wind direction 4 is controlled. In the above steps, step (31) executes the specific section setting means 20, step (32) executes the temperature difference detection means 21, and steps (33) to (37) execute the wind direction change control means 22. It is a step.

In this way, if the location where the user is located is set as a specific section using the switch 16, the louver 3 will remain facing that specific section for a period of time when the temperature difference between the room temperature and the set room temperature is large. In other words, the time during which the blowing air direction 4 is oriented in that section is increased to improve the comfort of the user, and when the temperature difference becomes smaller, the stop time is shortened to equalize the temperature of the entire room.

In the above embodiment, an example was shown in which the blowing wind direction was divided into eight equal parts, but it may be divided into any number of parts, and the stop time in a specific section is not limited to the characteristics shown in Fig. 4, and the Although the louver is controlled to stop at the same time, it may be moved continuously and the moving speed may be changed by the reciprocal of the stop time ratio shown in FIG. 5 for each section. Further, the stop time ratio for each section is not limited to that shown in FIG. 5, and the stop time ratio may be changed depending on the temperature difference. For example, while the temperature difference is large, the stop time can be changed for each section, but when the temperature difference is small, the stop time for each section can be made equal.

As described above, various fine control of the blowing air direction is possible.

Although the temperature signal and the setting signal are wirelessly transmitted to the indoor unit 1 by the remote control 9, they may be sent by wire, or sensors and setting devices may be attached to the indoor unit 1.

[Effects of the Invention] As described above, the present invention divides the blowing air direction into a predetermined number, sets one section among them, and calculates the temperature difference between the current room temperature and the set room temperature during the period when the blowing air direction is in that section. The time when the blowing wind direction is in a section other than the specific section set above is made smaller as the section is further away from this specific section, so you can freely select the section you want from the air-conditionable space and check that section and its surroundings. This has the effect of providing an air conditioner control device that can finely control and automatically optimize the air conditioning conditions in the air conditioner, thereby improving comfort.
