Abstract

PURPOSE:To perform unified control and individual control on plural sets of air conditioners of the same kind provided in the same room when they are operated, by providing a receiving section which can receive a peculiar code only at the main body of each air conditioner and transmitting different codes. CONSTITUTION:By inverting the '0' and '1' of leader codes for designating the leading edges of transmission codes from a transmission circuit 1 by means of the program of the built-in microcomputer of a control circuit 2 by opening and closing the switching circuit 5 of a remote controller, the transmission codes are transmitted to air conditioners having different transmission codes. The receiving circuit 6 of the main body of each air conditioner receives its own code which is set by a switching circuit 8 through a control circuit 7. Therefore, the air conditioners are individually controlled. On the other hand, when the leader codes for designating the leading edges are set by the switching circuit 5, same control can be performed on the air conditioners.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an air conditioner controlled by a remote controller that transmits an optical signal to the air conditioner main body.

[Conventional technology]

Figure 8 shows the format of a transmission code in a conventional air conditioner as shown in, for example, Special IJI Publication No. 60-7295. It consists of an operating state setting code for setting the state, a checksum reader code for code quotation, and a checksum code for checking the above custom code and operating state setting code.

In conventional air conditioners, the main body air conditioner is controlled by transmitting the transmission code to the corresponding heavy equipment. The configuration of the above transmission code (the same code will be sent to all the same models, and the same control will be performed.

[Problem that the invention seeks to solve]

Conventional air conditioners are controlled by a transmission code configured as described above, but in places where multiple units of the same model are installed in the same room, the remote controller 1
There was a problem in that all units were controlled in the same way at the same time and could not be controlled individually.

This invention was made to solve this problem, and it is the same *! The purpose is to obtain an air conditioner that enables individual control when multiple units are operated.

[Means for solving problems]

The air conditioner according to the present invention is provided with a transmitting means that can send different codes to a plurality of air conditioner bodies, and a receiving means that can select a unique receivable code.

[For production]

In this invention, when operating multiple units, each receiver is set to receive only a unique code, and a different transmission code is sent to each receiver by switching the ports of a microcomputer built into the remote controller. Transmission and reception are performed by switching the ports on the microcontroller, and control is performed individually.

〔Example〕

Embodiments of the air conditioner according to the present invention will be described below with reference to the drawings. Figure 1 shows a remote controller, in which 1 is a transmission circuit having a transmission element such as an infrared light emitting diode, 2
is a room temperature detection circuit and a control circuit that converts transmitted data.

This control circuit 2 has a transmission port I! s1, switch circuit 3,
An excitement detection circuit 4 and a switching circuit 5 are connected. A lift detection element P4, a thermistor, etc. have been used for a while, and switching #5 is for switching the transmission code, etc.

Figure 2 is a configuration diagram of the air conditioner main body, which has 45 receivers.
In FIG. 2, 6 is a receiving circuit having a receiving element such as a diode, and 7 is a control circuit for controlling the main body of the air conditioner. 8 is a switching circuit such as a switch for setting a unique code.

Also, Fig. 3 has the same configuration, but Fig. 2 shows switching times: t
P18 is open, and in FIG. 3, switching circuit MPt8 is closed.

FIG. 4 shows the transmission code when the switching circuit 5 in FIG. 1 is closed, and FIG. 5 shows the transmission code when it is opened. Furthermore, FIG. 6 is a diagram showing the structure of the transmission code.

The switching circuit 8 for switching the reception code of the air conditioner body shown in FIGS. 2 and 3 has different settings.

Next, it is shown in Figure 1. 11-- 1- Open and close the switching circuit 5 of the controller, and invert rOJ and rlJ of the glue code for specifying the beginning of the transmission code using the built-in microphone 4 computer program, and change the values shown in Figs. 4 and 5, respectively.
The transmission code shown in the figure is sent to each set air conditioner to control it.

Since the receiving 1 circuit 6 of the air conditioner body can only receive the code (FIG. 4 or 5) set by the receiving code switching circuit 8, each code is controlled individually.

FIG. 4 shows the transmission code when the switching time: IPI8 is closed, and FIG. 5 shows the transmission code when IJFf is selected. Individual control is performed by determining the leading code for designation.

In the above embodiment, the leading designation league code of the transmission code is inverted and controlled individually, but it is also possible to provide a switching code in the transmission code diagram.

The league code for specifying the beginning of the transmission code chart shown in Figure 6 remains unchanged, and individual control is performed by changing the switching code. When set to L, the code structure becomes as shown in FIG.

〔Effect of the invention〕

As explained above, in this invention, each air conditioner main body is provided with a receiving section that can receive only its own unique code, and each different code is transmitted by the transmitting means. By simply switching the switching circuits of the unit and remote controller, it is possible to operate multiple units of the same model in the same room and perform the same control or individual control, which has the effect of creating a more diverse air-conditioned environment.
