Description

Detailed Description of the Invention (a) Industrial Application Field This specification applies to the operation of an air conditioner, such as switching between starting and stopping an air conditioner, switching between cooling operation and heating operation, and changing the room temperature set point. Air conditioners that can be controlled from a remote location by using a remote controller, such as change of wind speed, change of wind speed, timer operation time setting, etc. This invention relates to an air conditioner that can be controlled.

(b) Prior art Generally, the operation of an air conditioner in which a refrigeration cycle is constructed by sequentially connecting a compressor, condenser, pressure reducing device, and evaporator in a ring with refrigerant piping, such as switching between starting and stopping the operation of an air conditioner. , switching between cooling and heating operations, changing room temperature settings, changing wind speed, setting timer operation, etc. were performed by separating the remote controller from the air conditioner itself and operating this remote controller.

In such cases, the air conditioner main body and the remote controller are connected by a multicore cable.

Therefore, if it is desired to use the remote controller far away from the main body of the air conditioner, the installation of the multi-core cable is long and difficult, which may lead to malfunctions.

Therefore, an attempt was made to connect the air conditioner main body and a remote controller with a pair of signal lines, as described in Japanese Patent Application Laid-Open No. 56-155326. In this case, it was possible to control not only the start and stop operations of the air conditioner, but also many operating conditions such as room temperature settings and timer operation time settings, but in this case as well, same as above. , it was necessary to install a pair of signal lines between the air conditioner itself and the remote controller.

Furthermore, when considering indoor air conditioning using an air conditioner, it is insufficient to simply control the indoor air temperature. In other words, in addition to controlling indoor ventilation and humidity, it was also necessary to control indoor illuminance, but when performing such control, it is necessary to separately install ventilation fans, humidifiers, defomers, and indoor illuminance control. It was cumbersome to control additional devices such as containers individually.

If such an additional device is integrated into the main body of the air conditioner Sagami, it can be controlled with a single remote controller, but this increases the size of the air conditioner and complicates its structure. It was something that I had.

(c) Purpose of the Invention In view of the above problems, the air conditioner of the present invention can freely set the separation distance between the air conditioner main body and the remote controller, and can also control additional devices such as ventilation fans and humidifiers at the same time. The present invention provides an air conditioner that can perform the following tasks.

B) Structure of the Invention The present invention provides an air conditioner consisting of an air conditioner main body and a remote controller, in which signals are transmitted and received between the air conditioner main body and the remote controller using commercial power wiring, and the remote controller The operation of other additional devices can be controlled using the commercial power wiring, making it possible to comprehensively control not only the indoor temperature but also ventilation fans, humidifiers, lighting, etc. .

shall be. Below, it is best to assign other additions [1] to the remaining channels depending on the decoration.

Therefore, when operating this device, the switch of channel "1" of the remote controller (2) is pressed to output an operating signal to the air conditioner main body (4). After changing the set value using this operation, if you press the setting completion switch (G), this set value will be sent to the air conditioner main unit (4), and the air conditioner main unit (4) will be changed based on this set value. Driving takes place.

That is, the operation of this remote controller (2) is performed once based on the flowchart shown in FIG. First, channels are scanned, and if the channel section αη is operated, an operation signal specifying the device corresponding to that channel is output. In the case of a stop operation, a stop signal is sent.

Next, if the channel section (177) is not operated and channel "1" is in the ON state, the air conditioner Sagami main body (

If the state is N, this display will not be performed. Furthermore, if there is a change in the operating state at this time, the set value after this change is transmitted to the air conditioner main body (4).

The operation of the air conditioner main body (4) is controlled based on the set values transmitted in this way.

In addition, if the indoor air becomes dirty due to continued operation of the air conditioner, turn on channel ``2'' of the remote controller (2).
”, the outlet adapter (6) set to channel “2” will operate and the ventilation fan (1 (11)
is energized and ventilation operation begins.

At this time, the outlet adapter (6) receives only the (hT signal) of the set channel and controls the normally open contact piece C3υ.Similarly, when installing humidifying operation, use the remote controller (2). When the switch of channel "3" is pressed, humidification operation is started.

In this way, the single remote controller (2) can simultaneously control the continuous operation of the air conditioner main body (4) and the operation of other additional devices. Further, the additional devices are not limited to those mentioned above, and a dehumidifier, illuminance control device for lighting, etc. may also be used.

(F) Effects of the Invention As described above, the present invention provides an air conditioner consisting of an air conditioner main body and a remote controller, in which signals are sent and received between the air conditioner main body and the remote controller using commercial power wiring, In addition, this remote controller is designed so that the operation of other additional devices can be controlled using the commercial power wiring, so that signals can be sent and received between the air conditioner main body and the remote controller using the commercial power wiring. This eliminates the need for wiring work for signal lines, and widens the range of options for installing the remote controller. Furthermore, since the air conditioner main body and the additional devices that are separately pressurized can be controlled simultaneously with a single remote controller, the indoor space can be controlled much more easily than in the past.
