Abstract

PURPOSE:To enable comfortable air conditioning with a living space in a room as a center, by a method wherein an operating part and a main body of an air conditioner are provided respectively with sensors for detecting room environments, environmental data are determined by using detection data obtained by the sensors as elements, and the operation is controlled. CONSTITUTION:Where detected temperature data Q1 obtained by a room temperature sensor 16 in the operating part 10 are quite different from detected temperature data Q2 obtained by a room temperature sensor 5 provided on the side of the main body 1, the temperature data Q2 on the main body 1 side are outputted as room temperature data. On the other hand, where the data Q1 and the data Q2 are approximate to each other, calculations are conducted with the temperature data as elements, and the results Q3 are outputted as room temperature data. A controller 25 compares the room temperature data Q2 or Q3 indicated by an output Q5 from a selecting means 23 as room temperature data with a set temperature Qs, and controls a compressor 33. Accordingly, it is possible to appropriately control the operation while taking into account both the temperature in the vicinity of the operating part and the temperature in the vicinity of the air conditioner.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a method for controlling the operation of an air conditioner equipped with a remote controller type operation section.

[Technical background of the invention]

Conventionally, in air conditioners, an indoor temperature sensor is installed in the remote control operation unit, and the temperature detected by the indoor temperature sensor is used as room temperature data.The indoor temperature is controlled according to this room temperature data. There are devices designed to provide comfortable air conditioning mainly in living spaces.

However, in such an air conditioner, if the operating unit is hidden behind an object 9 or if the operating unit is exposed to direct sunlight, it becomes impossible to properly detect the indoor temperature. For this reason, the reality is that it cannot always be said that comfortable air conditioning can be achieved.

Therefore, an indoor temperature sensor is installed not only in the operating unit but also in the air conditioner itself, and when the difference between the detected temperature on the air conditioner main body side and the detected temperature on the operating unit side is extremely large, the operating unit side There is a system that determines that the temperature is not appropriate and controls the operation using the temperature detected by the air conditioner itself. However, in this case, if the difference in the detected temperatures is not that large, even if the temperature detected by the operation control section is not appropriate, the operation will eventually be controlled based on the temperature detected by the operation control section. However, depending on the arrangement of the temperature sensor, there may be a delay in response to the temperature detected by the operating section, making it difficult to properly detect the room temperature.

[Purpose of the invention]

This invention was made in view of the above circumstances,
The purpose of this is to determine the room temperature based on the detection data of the sensors for indoor environment detection in both the remote control operating unit and the air conditioner itself, and to obtain environmental data that matches the actual indoor environment. An object of the present invention is to provide an excellent method for controlling the operation of an air conditioner that can provide comfortable air conditioning mainly for indoor living spaces. Sensors for detecting the indoor environment are provided in the air conditioner and the air conditioner body, and environmental data is determined using the detection data of each sensor as an element, and the operation of the air conditioner is controlled in accordance with this environmental data.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings.

In Figure 2, 1 is the air conditioner main body, air intake port 2
．． Air outlet 3. It has a light receiving section 4 and the like. The air suction port 2 is provided with an indoor temperature sensor (thermistor) 5, which is a second sensor for detecting the indoor environment. On the other hand, 10 is a wireless remote control operation unit with an ON switch 11, an OFF switch 12,
It has a temperature setting switch 13, a sensor housing section 14 housing an indoor temperature sensor 16 (to be described later), a transmitting section 15, etc., and transmits various information to the air conditioner main body 1 by, for example, infrared rays.

FIG. 1 shows the control circuit.

First, in the operation unit 10, reference numeral 16 is an indoor temperature sensor (thermistor) which is the first sensor for detecting the indoor environment, and the output of this indoor temperature sensor 16 is A/D (
The signal is converted into a digital signal by an analog/digital converter 17, and is supplied to a transmission signal converter 18 as a sensor signal S1. This transmission signal converter 18 converts the output signals (digital signals) of the A/D converter 17, ON switch 11, OFF switch 12, and temperature setting switch 13 into serial signals of a predetermined arrangement, and converts them into serial signals of a predetermined arrangement. It is supplied to the transmitter 15. The transmitting section 15 transmits the serial signal supplied from the transmitting signal converting section 18 to the air conditioner main body 1 by light emission from the infrared light emitting diode 15a.
The output of the indoor temperature sensor 5 is converted into a digital signal by an A/D converter 21. The receiving section 4 has a photodiode 4a that receives infrared rays, and receives a signal transmitted from the operating section 10. The received signal from the receiving section 4 is decoded by the received signal decoding section 24, and the decoded signal is supplied to the control section 25, the sensor signal determining section 26, and the ON/signal determining section 27, respectively.

The sensor signal determination section 26 extracts the sensor signal S from the signal decoded by the received signal decoding section 24 and supplies it to the comparison means 22 and the calculation means 28.

Each of the comparison means 22, calculation means 28, and selection means 23 will be explained below. The comparison means 22 receives a sensor signal S from the indoor temperature sensor 5 of the air conditioner body and a sensor signal S from the indoor temperature sensor 16 of the operation section 10.

And detected temperature data Q of both sensor signals S2 and sl.

The difference in Ql is calculated, and the absolute value of the calculated temperature difference is compared with a value multiplied by a predetermined value of the temperature data Q1 detected by the indoor temperature sensor on the air conditioner main body side.

That is, I QI Q2'l and αQ+ (α is the constant of proportionality)
A comparison is made. And,' Q+ Q21>αQ
Different signals s4 are sent to the selection means 23 in the case of , and in the case of .I Q+ 921≦αQ1.

Further, the calculation means 28 inputs both sensor signals S8, S, performs a predetermined calculation on both detected temperature data Q0, Q2, and outputs the result as a signal S to the selection means 23.

At this time, the calculation content performed by the calculation means 28 is Q.

-(aQ++bQ2)/(a+b) (a and b are constants), and the signal S3 sent to the selection means 23 is a kind of temperature data Q3.

Then, the selection means 23 uses the sensor signal S2 and the calculation means 28.
The calculation result signal S3 of the comparison means 22 and the comparison result signal S4 of the comparison means 22 are input, and the comparison result signal S4 is
When αQ1 is indicated, the sensor signal S is output as the selection result signal S, and the comparison result signal S4 is "Ql' Q2)≦
In the case of αQ, the calculation result signal S3 is output as the selection result signal S to the detected temperature data input section of the control section 25.

The control section 25 controls the operation of the indoor fan 31, the outdoor fan 32, and the compressor 33, respectively, based on the decoded signal from the signal decoder 24 and the signal S supplied from the selection means 23.

The operation of each means 22, 28, and 23 having the above configuration is as shown in control flowchart 1 in FIG. If the detected temperature data Q is far from the detected temperature data Q of No. 5, and if the detected temperature data Q2 on the main body side is close, a calculation is performed using both detected temperature data as elements, and the result Q3 is output as room temperature data.

Then, the control unit 25 uses the room temperature data Q or Q indicated by the output S of the selection means 23 as room temperature data to set the set temperature QS.
The compressor is controlled by comparing the

As described above, in this embodiment, calculation is performed using both the detected temperature Q1 on the operation unit 10 side and the detected temperature Q on the main body side as elements, and the operation of the air conditioner is controlled using the calculation result as room temperature data. Therefore, it is possible to perform appropriate operation control that takes into account both the humidity near the operation unit and the temperature near the air conditioner.

In addition, in this embodiment, if the difference between the detected temperature Q1 on the operation unit side and the detected temperature Q on the air conditioner main body side is large, the detected temperature on the air conditioner main body side, which has high stability and reliability, is used. Since operation control is performed, stable air conditioning is possible even if the operation unit is placed in an inappropriate position or a faulty signal is sent due to a failure of the operation unit.

In this embodiment, each sensor detects the indoor temperature, but it is also possible to detect other factors such as indoor humidity. Further, the calculation of the detection data of each sensor is not limited to the calculation of the above embodiment, and other calculations using both data as elements may be set as appropriate. [Effect of the Invention] The present invention provides a remote control A first sensor installed in the operation control section of the air conditioner and a second sensor installed in the air conditioner body.
Environmental data is determined based on the detection data of both sensors, and the operation of the air conditioner is controlled according to the determined environmental data, making it possible to perform appropriate operation control according to the overall indoor condition.
