Abstract

(57) [Summary] [Problem] To obtain a temperature of a place to be subjected to air-conditioning control without directivity and in a form advantageous for carrying. SOLUTION: The output of a temperature measuring element 15 provided in a remote controller 1 is transmitted via an A / D converter 13 from a transmitter 12 to a receiver 2 on a radio wave 4. The receiver 22 included in the receiver 2 transmits the ambient temperature measured by the remote controller 1 to the controller 3 of the air conditioner main body 5 via the transmitter 23.
Due to its good portability and the omnidirectionality of the radio wave 4, the remote controller 1 transmits the ambient temperature of the place to the air conditioner main body 5 regardless of the place where the air conditioning control is to be performed. Air conditioning control of the place can be performed appropriately.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for transmitting an ambient temperature to an air conditioner body.

[0002]

2. Description of the Related Art FIG. 4 is a schematic diagram showing a conventional indoor air conditioning control technique. In the room, a wind 203 providing a comfortable temperature to the person 7 is blown by the air conditioner 20 installed on the ceiling 6.
0 is blown out from the outlet 200b.

In order to adjust the temperature of the wind 203 so as to provide a comfortable temperature to the person 7, the temperature of the place where the person 7 is located (hereinafter referred to as "ambient temperature") is detected, and air conditioning is performed based on the detected temperature. You need to take control. However, conventionally, for example, air conditioning control has been performed based on a temperature measured by a temperature measuring element provided at a suction port 200a of the air conditioner 200.

[0004]

However, even if the temperature near the air conditioner 200 installed on the ceiling 6 is detected by the temperature measuring element, the ambient temperature of the person 7 below the ceiling 6 is properly detected. Can not. Alternatively, the air conditioner 200 is used as a main body, and a remote controller (hereinafter, abbreviated as “remote control”) 201 for controlling the operation of the main body is installed near the height of the person 7 on the wall surface of the room, and a temperature measuring element is provided on the wall. However, the ambient temperature of the person 7 away from the wall cannot be properly detected. These are, of course, due to the fact that no temperature measuring element is provided at the place where the person 7 is.

Therefore, it has been proposed to provide a temperature measuring element in a wireless remote controller. However, since the wireless remote controller that has been used in the past uses infrared rays for transmission to the air conditioner main body and has directivity from the remote control to the air conditioner main body, the wireless remote control does not necessarily transmit from the place where the person 7 is present to the air conditioner 200. It was not always possible. In addition, since a temperature measuring element is newly provided in a remote controller for controlling the operation of the main body, a large size is required, and it is inconvenient to carry the person 7 so as to always detect the ambient temperature.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and provides a technique for obtaining a temperature of a place to which a wind having a comfortable temperature is to be supplied without directivity and in a form advantageous for carrying. It is.

DESCRIPTION OF THE PREFERRED EMBODIMENTS First Embodiment FIG. 1 is a block diagram conceptually showing the configuration of the first embodiment of the present invention. Remote controller 1 that transmits ambient temperature to air conditioner body 5
Is a temperature measuring element 15 such as a thermistor for measuring the ambient temperature.
An A / D converter 13 for converting an output of the temperature measuring element 15 having an analog signal form into a digital signal form;
The main component is the transmission unit 12 that receives the output of the / D conversion unit 13 and transmits the output using the radio wave 4.

The remote controller 1 is necessary for a normal remote controller.
Since it is not necessary to provide a configuration for transmitting control factors such as the desired setting temperature, air volume, and air direction to the air conditioner main body 5, the configuration can be made compact and the portability is excellent. Moreover, since the ambient temperature detected by the temperature measuring element (hereinafter referred to as “detected value”) is transmitted by the radio wave 4 using the transmitting unit 12 and the antenna 11 connected thereto,
There is no directivity like transmission by infrared. Therefore, it is possible to accurately transmit the ambient temperature of a person, animals and plants to the air conditioner main body 5 from anywhere in the room without selecting a place where the ambient temperature is to be measured.

Further, in order to display the ambient temperature, the remote controller 1 desirably further includes a display unit 14 which receives the output of the A / D conversion unit 13 and displays it. Transmission unit 12, A
Since the / D conversion unit 13 and the display unit 14 are supplied with power from the battery 16, the user not only displays the ambient temperature but also checks whether the battery 16 has run out and the radio wave 4 has stopped. Can be monitored.

The air conditioner main body 5 includes a receiver 2 for receiving a radio wave 4 transmitted from the remote controller 1, and a control unit 3 for controlling the operation of the air conditioner main body. Receiver 2 has radio wave 4
, An antenna 21 and a receiving unit 22 for receiving a signal, a temperature detecting unit 24 for measuring a temperature separately from the remote controller 1, an output of the receiving unit 22 and an output of the temperature detecting unit 24, and input under a predetermined condition. And a transmission unit 23 for selectively D / A converting any one of them and transmitting it to the sensor input unit 3a of the control unit 3. The controller 3 is, for example, a printed circuit board for indoor units (commonly called “indoor P board”) provided in the air conditioner main body 5.

The temperature detecting section 24 functions similarly to a conventional temperature measuring element at the suction port, and includes a temperature measuring element 24a such as a thermistor and a temperature measuring element 24 having an analog signal form.
a / D conversion unit 24b for converting the output of A into a digital signal. That is, under the predetermined condition, the transmission unit 23 performs the air conditioning control based on the temperature of the suction port as an auxiliary of the ambient temperature obtained from the remote controller 1.

The transmission unit 23 is a selector 23a for outputting either the output of the reception unit 22 or the output of the temperature detection unit 24 under the control of the reception unit 22, and the sensor input by converting the output of the selector 23a into an analog signal. And a D / A conversion unit 23b to be provided to the unit 3a.

Here, the predetermined condition is considered to be a malfunction of the remote controller 1 as one specific example. For example, battery 1
6 is cut off and the radio wave 4 from the remote controller 1 stops,
The receiving unit 22 responds accordingly to the selector 23a.
The output of the A / D converter 24b is provided to the D / A converter 23b. Otherwise, the output of the receiving unit 22 is given to the D / A conversion unit 23b. Even if an operation failure of the remote controller 1 occurs, the air conditioning is controlled based on the auxiliary measured temperature, so that the temperature control by the air conditioner main body does not become extremely difficult.

The receiving unit 22 determines, for example, that the radio wave 4 from the remote controller 1 has stopped, based on the fact that the detection value has not been transmitted for a certain period of time. Therefore, it is desirable that the remote controller 1 transmits the detection value at an interval shorter than a certain period. On the other hand, when the fluctuation of the ambient temperature is small,
Accordingly, it is not necessary to frequently perform the air conditioning control of the air conditioner. Since power is supplied to the remote controller 1 from the battery 16 due to the requirement of portability, it is desirable not to perform transmission when fluctuations in the ambient temperature are small in order to save power.

Therefore, it is desirable that the transmitting unit 12 operates in accordance with the flowchart shown in FIG. 2 so as to transmit the detected value at an appropriate timing in response to an appropriate change in the ambient temperature.

In step 101, it is determined whether the time D has elapsed since the last time the detected value was read.
This determination is whether the transmission unit 12 has read the output of the A / D conversion unit 13 or not, even if the A / D conversion unit 13 has read the detection value from the temperature measuring element 15. Or any of them. Here, if the determination is No, the process returns to step 101. This is because it is not always necessary to continuously transmit the detection value in the air conditioning control.

If it is determined Yes in step 101, the detected value is read in step 102.
As described above, this may be understood as that the transmission unit 12 reads the output of the A / D conversion unit 13 or that the A / D conversion unit 13 reads the detected value from the temperature measuring element 15. .

Then, the process proceeds to a step 103, wherein the difference between the previous detection value and the current detection value is less than A degree, for example, 0.2 ° C.
It is determined whether or not: Ambient temperature fluctuation is 0.
If the temperature is equal to or lower than 2 ° C., it is not necessary to substantially change the air conditioning control by the air conditioner, and there is a possibility that the detection value need not be transmitted. On the other hand, if the fluctuation of the ambient temperature exceeds 0.2 ° C., it is necessary to change the air-conditioning control, so the process proceeds to step 106 to transmit the detected value. Step 106
Is executed, the process returns to step 101.

If it is determined in step 103 that the difference between the previous detected value and the present detected value is not more than A degrees, then in step 104, the difference between the previously transmitted value and the previously transmitted value is B.
It is determined whether the degree is equal to or higher than the degree. For example, even when the detected value fluctuates below A degrees at time D, a case is considered in which the detected value monotonously increases or decreases and the ambient temperature changes greatly. That is, the detected value is 2 for each time D.
When the temperature rises to 5 ° C., 25.2 ° C., 25.4 ° C., 25.6 ° C., etc., it is obvious that it is not desirable to leave such a state without transmitting the detected value. Therefore, for example, 0.5 ° C. is adopted as the B degree so that there is no fluctuation that greatly exceeds 0.5 ° C. between the detected values to be transmitted, so that the air conditioning control is properly performed. For this purpose, B degree is A
It is set larger than the degree.

If it is determined Yes in step 104, the flow advances to step 106 to transmit the detected value.
Determining o does not mean that the detected value is not transmitted. As described above, in order to prevent the receiving unit 22 from judging the stop of the wave, if the transmission interval of the detection value exceeds a certain time C in step 105, the process proceeds to step 106 to transmit the detection value. If the time C has not elapsed, the process returns to step 101.

Note that a period obtained by adding the time D to the time C is basically used as a criterion for the receiving unit 22 to judge the suspension of the wave. Since it is determined in step 105 whether the transmission interval of the detected value exceeds the time C, if the determination in step 105 is Yes and the process proceeds to step 106, the transmission interval is time (C + D). This is because it may include the case of More precisely, a period obtained by adding the execution time of each flow to the time (C + D) is used as a criterion of the stop of the wave.

Second embodiment. FIG. 3 is a conceptual diagram showing a second embodiment of the present invention. Two air conditioner bodies 5a and 5b are installed on the ceiling 6 in the same room. In this case, the area in which each of the air conditioner bodies 5a and 5b is in charge of air conditioning is roughly divided into areas 9a and 9b located below the respective areas. In such a case, the areas 9a and 9
b, the remote controllers 1a, 1b
The respective ambient temperature should be transmitted to 5b.

However, since the ambient temperature is transmitted using the radio wave 4 having no directivity as a feature of the present invention, the radio wave 43 from the remote controller 1b located in the area 9b is also transmitted to the air conditioner main body 5a.
To reach. Conversely, the radio wave 42 from the remote controller 1a located in the area 9a also reaches the air conditioner main body 5b. The detected values given to the remote controllers 1b and 1a by the radio waves 42 and 43, respectively, are not appropriate ambient temperatures.

Therefore, the remote controllers 1a and 1b transmit radio waves to which unique codes are added. And the air conditioner body 5
Based on this unique code, a and 5b recognize the radio waves 41 and 44 from the remote controllers 1a and 1b as being for themselves, and do not recognize the radio waves 42 and 43 as being for themselves. By doing so, the air conditioner main bodies 5a and 5b can appropriately obtain the ambient temperature in the areas 9a and 9b to which they are to be assigned.

[0041]

According to the remote controller according to the first aspect of the present invention, the air conditioner main body can control the temperature by accurately reflecting the ambient temperature at the position of a person, animals and plants. Also, because it is wireless and without directivity,
The ambient temperature can be transmitted to the air conditioner body from any direction.

According to the remote controller according to the second aspect of the present invention, power can be saved by not performing transmission when temperature control in the air conditioner body is substantially unnecessary.

According to the remote controller of the third aspect of the present invention, the ambient temperature is transmitted to the air conditioner little by little, even when the detected value changes with time. be able to.

According to the remote controller of the fourth aspect of the present invention, the power consumption is reduced, and the detected value is not greater than the sum of the first predetermined period and the second predetermined time. Since the information is transmitted to the air conditioner main body, it is possible to make the air conditioner main body confirm that the remote controller is operating.

According to the remote controller according to the fifth aspect of the present invention, since the ambient temperature is displayed, the user can confirm the operation of the remote controller, and whether or not the operation is transmitted. Can be monitored.

According to the remote controller according to the sixth aspect of the present invention, even when there are a plurality of pairs of the air conditioner main body and the remote controller, each of the air conditioner main bodies is controlled by a remote controller not corresponding to itself. Of the detected value is not erroneously used as the basis of its own temperature control.

According to the receiver of the present invention, since the temperature is measured supplementarily even if the remote controller does not operate, the temperature control by the air conditioner main body becomes extremely difficult. Nothing.

According to the receiver of the present invention, whichever of the ambient temperature obtained by the temperature measuring element and the ambient temperature obtained from the remote controller is transmitted to the air conditioner body, It is transmitted in a consistent manner as an analog signal.
