Abstract

PURPOSE:To realize inexpensively the system control of an air-conditioning machine, for which the promotion of the function thereof is required recently, by a method wherein the information collected by an outdoor machine and the information collected in an indoor machine are processed in the outdoor machine while the indoor machine and the outdoor machine are controlled as one system. CONSTITUTION:The information collected by the sensor 6 and the operating switch 7 of an indoor machine 1 is encoded by an encoder 8 and is transmitted to an outdoor machine 17 through the transmitting and receiving circuit 5 of the indoor machine 1, a signal wire 9 and the transmitting and receiving circuit 10 of the outdoor machine 17. The information of the indoor machine 1 is decoded by a decoder 18 and is inputted into an operation processing means 12. Simultaneously, the output information of the outdoor machine, issued from the sensor 15 and the operating switch 16 of the outdoor machine, is inputted into the operation processing means 12 while an operation process is effected in the operation processing means 12 on the information of the indoor machine and the information of the outdoor machine itself in accordance with a predetermined sequence whereby the operation modes of the outdoor machine 17 and the indoor machine 1 are determined. Subsequently, the operation processing means 12 controls the load 14 of the outdoor machine 17 through a driver 13 and controls also the load 2 of the indoor machine 1 through the encoder 11 and the driver 3.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an air conditioner that is separated into an indoor unit and an outdoor unit.

Conventional technology The commonly used home air conditioners are separated into an indoor unit and an outdoor unit, and the indoor unit performs arithmetic processing based on output information from operation switches and various sensors. The outdoor unit controls each function of the indoor unit and sends only necessary information to the outdoor unit.The outdoor unit also sends information sent from the indoor unit and output information from the operation switches and various sensors on the outdoor unit. In this method, various functions of the outdoor unit were controlled by performing arithmetic processing based on the above.

Problems to be Solved by the Invention Variable frequency control air conditioners, generally called inverter air conditioners, which have become popular in recent years, are required to provide more comfortable air conditioning, and the control of their functions has become extremely complex. Therefore, both the indoor unit and the outdoor unit are required to have higher functionality as arithmetic processing means.

However, the above-mentioned conventional control method requires such a highly functional arithmetic processing means for both the indoor unit and the outdoor unit, resulting in an increase in parts cost.

The present invention solves the above-mentioned conventional problems, and aims to inexpensively realize system control of air conditioners, which are required to be highly functional in recent years.

Means for Solving the Problems In order to solve the above problems, the present invention sends all the information captured by the indoor unit to the outdoor unit, and combines the information captured by the outdoor unit with the information captured by the outdoor unit.
The information captured by the indoor unit is processed by the outdoor unit to control the indoor and outdoor units as one system.With this control method, all information is sent to the outdoor unit. It collects information, performs arithmetic processing on the collected information as an air conditioner system, and controls the outdoor unit itself and the indoor unit.

EXAMPLE An example of the present invention will be described below with reference to the drawings. In the figure, 1 is an indoor unit, which is configured as follows. That is, it includes an encoder 8 that encodes input information, inputs output information from the sensor 6 and the operation switch 7, encodes this information, and outputs the encoded information to the transmitting/receiving circuit 6. It also includes a decoder 4 that decodes the encoded input signal, decodes the signal input from the transmitting/receiving circuit 5, and
The load 2 is controlled through. The transmitting/receiving circuit 5 sends input signals from the encoder 8 to the outside through a signal line 9,
The received signal from the signal line 9 is sent to the decoder 4.

On the other hand, the outdoor unit 17 is configured as follows.

That is, it is equipped with an arithmetic processing means 12, inputs the output information of the sensor 15, operation switch 16, and decoder 18, performs arithmetic processing according to a predetermined procedure,
The encoder 11 controls the load 14 through the encoder 11.
Control information to the indoor unit 1 is output to the indoor unit 1. The encoder 1
1 encodes the control information for the indoor unit input from the arithmetic processing means 12 and outputs it to the transmitting/receiving circuit 10.

It is also equipped with a decoder 18, which inputs signals transmitted from the indoor unit through the transmitter/receiver circuit 10, decodes them, and outputs information to the arithmetic processing means 12.

In the above configuration, the information that the indoor unit 1 captures is the sensor 6 and the operation switch 7, but this information is transmitted to the encoder 8.
The transmission/reception circuit 5 of the indoor unit 1, the signal line 9,
Sends 2 to the outdoor unit 17 through the transmission/reception circuit 10 of the outdoor unit 17
). In the outdoor unit 17, the encoded information of the indoor unit 1 is decoded by a decoder 18 and inputted to the arithmetic processing means 12. At the same time, the output information of the sensor 15 and operation switch 16 of the outdoor unit itself is also input to the calculation processing means 12, and the calculation processing means 12 uses the information of the indoor unit and the information of the outdoor unit itself to determine the The operation mode of the outdoor unit 17 itself and the operation mode of the indoor unit 1 are determined by performing arithmetic processing according to the procedure. Next, the arithmetic processing means 12 controls the outdoor unit 17 through the driver 13 according to the determined operation mode.
For the indoor unit 1, control information for controlling the load 2 of the indoor unit 1 is output to the encoder 11. The encoder 11 encodes this control information,
The signal is transmitted to the indoor unit 1 through the transmitting/receiving circuit 10 of the outdoor unit 17, the signal line 9, and the transmitting/receiving circuit 5 of the indoor unit 1. The decoder 4 of the indoor unit 1 decodes the sent control signal from the outdoor unit 17 and controls the load 2 of the indoor unit 1 through the driver 3.

Effects of the Invention As is clear from the above description of the embodiments, according to the present invention, all the information is collected in the outdoor unit, so the indoor unit does not need arithmetic processing means to process the information. , it is sufficient to have an encoder that encodes information, a decoder that decodes the sent control signal, and a transmitting/receiving circuit, and the expensive arithmetic processing means that requires high functionality is provided only in the outdoor unit. Therefore, it is possible to realize an inexpensive control system that is highly functional as an air conditioner system.

In addition, in air conditioners, which are generally called multi-air conditioners, in which two or more indoor units can be connected to one outdoor unit, the information of each indoor unit and the information of the outdoor unit itself are combined into one. Since it can be processed by arithmetic processing means, it becomes possible to control the system in an extremely detailed and efficient manner as an air conditioning system.
