Abstract

PURPOSE:To individually control the operation of plural sets of the same type machine by providing a transmitting means for feeding codes different in length to plural air conditioning machine main bodies and a receiving means for selecting the proper code length capable of receiving. CONSTITUTION:At the time of operating two sets, the receiving code length of the air conditioning machine main body is set to the respectively different code length according to the opening and the closing of a change over circuit 8. The transmission codes different in the code length of A bits or (A+1) bits are transmitted to the respective air conditioning machine main bodies to control. In such case, since the air conditioning machine main body receives only the code of the code length set by itself, if the respectively different code length is transmitted from a remote controller, the plural sets of the air conditioning machine bodies of the same machine type in the same room can be respectively individually controlled.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an air conditioner, and more particularly to a control method that allows the air conditioner to be controlled by a remote controller that transmits optical signals to the main body of the air conditioner.

[Conventional technology]

FIG. 6 shows the format of a transmission code applied to the conventional air conditioner glue control disclosed in, for example, Japanese Patent Laid-Open No. 60-7295. This transmission code includes a leader code for specifying the beginning, a custom code for selecting the target device, an operating status setting code for setting the operating status, a checksum reader code for code separation, and the sum of the above custom code and operating status setting code. It consists of a checksum code for checking its custom code and operating status setting code.

However, in the conventional air conditioner, the main body air conditioner is controlled by transmitting the transmission code from the remote controller to the device to be controlled. In this case, the structure of the transmission code does not change, and the same code is transmitted to all the same models to perform the same control.

[Problem that the invention seeks to solve]

In the conventional air conditioner 8 as described above, when multiple units of the same model are installed in the same room, the same control is performed on all units at the same time with one remote controller, and the operation of multiple units is controlled individually. The problem was that it was not possible.

This invention was made to solve the above-mentioned problems, and an object of the present invention is to obtain an air conditioner that can individually control each of multiple units of the same model in operation.

[Means for solving problems]

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

[Effect]

In this invention, when multiple remote controllers are operated, different transmission code lengths are transmitted to the receiving sections each set to a unique code length, depending on the brightness of the port built in the remote controller, and this allows the same model enables individual control of

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings. 1st

2 is a room temperature detection circuit and a control circuit that converts transmission data; 3
Reference numeral 4 indicates a switch circuit for giving a control command, 4 a temperature detection element such as a room temperature thermistor, and 5 a switching circuit consisting of a switch for switching the length of a transmission code.

FIG. 2 is a configuration diagram of a receiving section built into the controlled air conditioner main body, where 6 is a receiving circuit having a receiving element such as a photodiode, and 7 is a control circuit for controlling the air conditioner main body. Reference numeral 8 denotes a switching circuit consisting of a switch and the like for setting the unique code length.

Also, FIG. 3 shows the receiving section of another air conditioner main body in the same way as FIG. 2, and the difference from FIG. 2 is that the switching circuit 8
is closed or open.

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.

Here, a case of two-unit operation will be explained.

The receiving code lengths of the air conditioner bodies shown in FIGS. 2 and 3 are set to different code lengths by opening or closing the switching circuit 8. Open or close the switching circuit 5 of the remote controller shown in Figure 1, and use the built-in microcomputer program to select a transmission code with a different code length of A bit or A+1 bit as shown in Figure 4 or Figure 5. It is sent to and controlled by each air conditioner. At this time, the air conditioner will only receive the code with the code length that it has set itself, so if you send a code with a different code length from the remote controller, you can receive multiple air conditioners of the same model in the same room. Each can be controlled individually.

〔Effect of the invention〕

As described above, according to the present invention, when multiple units of the same model are operated, it is possible to perform both the same control and individual control by simply switching the cord length switching circuit of the air conditioner body reception unit and the remote controller. This has the effect of creating an air-conditioned environment rich in air quality.
