付けられる。Problems to be Solved by the Invention However, with the above configuration, light from any direction is received as the same light, making it impossible to detect the position of the remote control. In order to make this possible, we provide a light receiving section in which multiple light receiving elements have directivity and are attached in different directions, and the strength of each received light signal is compared to determine the direction in which the strongest light is received. One possible method is to determine the location of the remote control. For example, when there are three light receiving elements, the light receiving elements are installed in the air conditioner in the orientation shown in FIG.

を招くという問題点を有していた。 However, even with the above configuration, the resolution of remote control position detection is limited to a maximum of three directions, especially in the seventh direction.
When the air conditioner is installed at the end of the room as shown in Figures P1 and P3, the resolution is essentially two directions, making it impossible to detect the remote control position satisfactorily. In order to increase this resolution, it is possible to increase the number of light receiving elements, but this has the problem of increasing cost and increasing the size of the device.

る。 First, when a control signal for the air conditioner is transmitted from the remote control, the control signal receiving section 5 receives it, and its output is input to the microcomputer 4. If this control signal is a signal other than a remote control position detection command, such as switching a set temperature or air volume, the air conditioner 11 is controlled by the microcomputer 4 based on the control signal, and waits for a remote control transmission again. Become. When the control signal is a remote control position detection command, the switch 36 is turned off and the switch 35 is turned on. Here, it is assumed that the switch 36 is normally turned on. Following the control signal, the remote control transmits an infrared signal for detecting the position of the remote control, and the light receiving elements 1a, 1b, and 1c receive this. At this time, the installation angle of the light receiving section is P R (to the right) as shown in FIGS. 1 and 4. The signals received by these three light receiving elements are amplified by amplifier circuits 2a, 2b, and 2c, respectively, and output as amplified signals 21, 22, and 23 via tuning circuits 20a, 20b, and 20c. These amplified signals 21, 22, 23 are input to a comparison circuit 3, which is divided into two parts. First, the first part is the diodes 3a, 3
This section is composed of switches 35, 36, resistor 37, capacitor 38, and comparator 34, and detects, holds, and compares the maximum intensity of the amplified signals 21, 22, and 23. The portion other than the above is a portion for comparing the intensities of the amplified signals 21, 22, and 23. In actual operation, the diodes 3a, 3b, 3c amplify the amplified signals 21, 2
The maximum value 30 of 2 and 23 is detected and this level is held in the capacitor 38 with a certain time constant.
After a certain period of time, the two input levels of the comparator 34 are equal, and the output of the comparator 34 is 0 (Lo output). Further, the amplified signals 21, 22, 23 are compared in strength by comparators 31, 32, 33 and a logic element. For example, if the remote control transmits a signal from the direction A in FIG. 4, the amplified signal 21 has the strongest strength among the three amplified signals, and the comparator circuit 3 outputs a binary number (001) 2 . Here, the most significant bit (hereinafter referred to as MSB) and the least significant bit (hereinafter referred to as LSB) of the binary number are the second
As shown in the figure. Similarly, if the remote control transmits a signal from direction B in FIG. ) 2 is output. These outputs are stored in memory 41 within microcomputer 4.

Install it on P L (left side) as shown in Figure 4. This P L
The light receiving elements 1a, 1b, 1c again receive the infrared signal for position detection, and the amplified signals 21, 22, 23 are input to the comparator circuit 3 in the same process as in PR . These amplified signals 21, 22, 23
The maximum value of is detected by the diodes 3a, 3b, and 3c, and compared with the maximum value of the amplified signal in PR held in the capacitor 38 by the comparator 34. Here, the maximum value in P R is P L
If larger than the maximum value in comparator 3
The output of 4, that is, the MSB, becomes 0 (Lo). In this case, the remote control position is determined to be in one of the directions A, B, and C in FIG. 4, and the contents of the memory 41 are not rewritten. Conversely, when the maximum value in P L is larger than the maximum value in P R , the output of the comparator 34, that is, the MSB becomes 1 (Hi). In this case, the intensities of the amplified signals 21, 22, 23 are further compared,
As in the case of PR , if the remote control is emitted from directions D, E, and A in Figure 4, the comparator circuit 3 outputs binary numbers (101) 2 , (110) 2 , and (111) 2 , respectively. be done. These comparison circuit outputs are stored in the memory 41
is memorized. Through the above process, if the contents of the memory 41 are (001) 2 or (111) 2 , the remote control position will be in the A direction, (010) 2 in the B direction, (011) 2 in the C direction, or (101). ) 2 is determined to be the D direction, and (110) 2 is determined to be the E direction. When the above position detection is completed, turn on the switch 36 again, and capacitor 3
Discharge the charge of 8.
