Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an air conditioner equipped with a remote control section generally referred to as a remote control.

<Prior art> This type of air conditioner equipped with a remote control unit allows a user to control the operation of the main body of the device, generally called an air conditioner, which is placed on a wall or the like in a room, by controlling the remote control unit from any living space. It can be controlled by wireless signals such as infrared rays transmitted from the remote control unit by operating the . For example, when a desired indoor temperature is set using the remote control unit, a control signal is sent from the remote control unit in response, and the set temperature is stored in the device itself, and the device body detects the temperature using a thermistor, etc. The circuit detects the ambient temperature and drives it to maintain the set temperature.

<Problems to be Solved by the Invention> However, in conventional air conditioners, for example, when adjusting the set temperature, a temperature detection circuit provided in the device body detects the temperature around the device body. The temperature of the surrounding area is considerably different from that of the user's living space where the remote control unit is installed or placed, due to the hot or cold air blown out from the main body of the device. That is, in reality, the living space whose temperature is to be adjusted often does not reach the set temperature, and comfortable air conditioning is not achieved.

The present invention has been made in view of these conventional problems, and provides a system in which the temperature of the living space where the remote control unit is installed or placed can be adjusted to a set temperature. The technical problem is to provide an air conditioner.

<Means for Solving the Problems> In the present invention, as a technical means for achieving the above-mentioned problems, an air conditioner is configured as follows. That is, in an air conditioner in which the main body of the device is driven and controlled by a wireless signal transmitted from the remote control section by operation of the remote control section, the main body of the device and the remote control section each include a wireless signal transmitting section. and a receiving section, the apparatus main body includes data request command means for automatically transmitting a request command signal for data held in the remote control section from the transmitting section, and The present invention is characterized by comprising answerback signal transmitting means for transmitting retained data corresponding to the received request command signal.

Effect〉.

With the above configuration, for example, when adjusting the set temperature, if the remote control section is also provided with a temperature detection circuit, when the remote control section is operated to set the desired temperature in the device main body, the device main body automatically adjusts. A built-in temperature detection circuit detects the surrounding temperature and drives the device to the set temperature.

When the temperature detected by the temperature detection circuit of the device body reaches the set temperature, a request command signal is automatically transmitted from the transmitting section of the device body, and when this is transmitted by the receiving section of the remote control section, the remote control In the section, the temperature difference between the temperature detected by the temperature detection circuit provided therein and the set temperature is calculated, and this temperature difference data is answered from the transmitting section to the main body of the apparatus. Thereby, the main body of the apparatus is controlled in accordance with the received temperature difference data, and the temperature around the remote control unit is adjusted to the set temperature.

<Embodiment> Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the drawings. . The remote control unit 1 includes a temperature sensor 3 such as a thermistor, a temperature detection circuit 4 that calculates the surrounding temperature based on the value of the temperature sensor 3, an operation key 5 for setting the temperature, etc., and overall control of the remote control unit 1. A transmitting section 7 transmitting control signals by infrared rays or the like according to commands from the microcomputer 6, and a receiving section 8 receiving signals from the main body 2 of the apparatus.

On the other hand, the device main body 2 includes a receiving section 9 that receives signals from the transmitting section 7 of the remote control section 1, a microcomputer 10 that controls the entire device main body 2, and various drive controls based on commands from the microcomputer 10. a temperature sensor 12 such as a thermistor; a temperature detection circuit 13 that calculates the ambient temperature based on the value of the temperature sensor 12;
A transmitting section 14 is provided that transmits a request command signal and the like based on instructions from the microcomputer 10.

Next, the operation of the embodiment will be explained with reference to the flowchart of FIG. First, manually operate the operation keys 5 of the remote control unit 1 to set the set temperature, etc. [Step (Sl)
) Then, the input data is transmitted from the transmitter 7 as a wireless signal by infrared rays or the like according to a command from the microcomputer 6 [step (32)]. This signal is received by the receiver 9 of the device main body 2 [step (S3)
) is received and processed by the microcomputer 10, and the control circuit 1) is received by the microcomputer 10.
controls the operation of the device main body 2 [step (S4)] in response to the received signal. Then, when the temperature detected by the temperature detection circuit 13 reaches the temperature set by the remote control unit 1 due to the operation of the main body 2 of the device, a request command signal is transmitted from the transmission unit 14 as a wireless signal such as infrared rays according to a command from the microcomputer 10. [Step (S5))].

When this request command signal is received by the receiving unit 8 of the remote control unit 1 (step (S6)), the temperature sensor 3 and the temperature detection circuit 4 detect the temperature around the remote control unit 1, that is, the temperature of the user's living space. [Step (S7)) is performed, and the microcomputer 6 calculates the temperature difference between the detected temperature from the temperature detection circuit 4 and the temperature set by the operation key 5 [Step (S8)], and this temperature difference data is transmitted. It is transmitted from the unit 7 [step (S9)]. This transmission signal is received by the receiving section 9 of the device main body 2 [step (SIO
)) Then, the operation control state is updated [step (Sll)) in accordance with the received temperature difference data.

Next, to explain the actual temperature control, when a cooling operation is commanded using the operation key 5 of the remote control unit 1 and the set temperature is set to 26°C, the control circuit 1) controls the operating state of the device main body 2. When the temperature data detected by the temperature detection circuit 13 of the main body 2 of the apparatus reaches a value equivalent to 26°C, a command from the microcomputer 100 sends a command signal requesting the temperature data detected by the remote control unit 1 to the transmitting unit 14.
Sent from. The remote control unit 1 receives this request command signal at the receiving unit 8, and then transmits the temperature sensor 3 and the temperature detection circuit 4.
When the ambient temperature is detected and the detected temperature is 28°C, the microcomputer 6 calculates +2°C, which is the difference from the set temperature of 26°C, and answers back this +2°C temperature difference data to the device body 2. . The main body 2 of the apparatus having received this temperature difference data updates the operation control state in accordance with the temperature difference data and continues the cooling operation since the ambient temperature of the remote control unit 1 has not reached the set temperature.

Further, if the temperature difference data answered back from the remote control unit 1 is +0° C., the device main body 2 controls the operating state to maintain the temperature.

It should be noted that the present invention is not limited only to the above description and illustrated examples, but may include various modifications without departing from the scope of the claims. For example, if the remote control unit 1 is equipped with an airflow (wind speed sensor), a radiant temperature sensor, a humidity sensor, etc., and the data detected by these sensors is sequentially answered back in response to a request command signal from the device main body 2, The air-conditioning condition of the living space around the remote control unit 1 can be detected very precisely and the air-conditioning condition can be controlled to be extremely comfortable.

Further, if the data value answered back from the remote control unit 1 is determined to be an abnormal value during reception processing by the microcomputer 10 of the device main body 2, the request command signal may be transmitted again. By doing so, highly reliable data can be obtained from the main body 2 of the apparatus.

<Effects of the Invention> Since the present invention is configured and operates as described above, it produces the following effects. In other words, the operation of the device itself can be automatically controlled in response to the air conditioning conditions of the user's living space in the vicinity where the remote control unit is located, resulting in very ideal control and extremely comfortable air conditioning conditions. can be obtained.
