Description

DETAILED DESCRIPTION OF THE INVENTION The present invention applies to electric circuits of air conditioners, such as remote operation circuits, remote operation display circuits, remote abnormality display circuits, residual heat removal circuits, interlock circuits, and timer circuits. The present invention relates to a circuit component connecting device for an air conditioner to which accessory components such as a room thermostat can be attached.

Conventionally, in order to assemble accessory parts such as remote control circuits and timer circuits to standard electrical circuits in air conditioners,
The electric circuit was significantly modified, and the electric circuit was changed to match the required specifications for each accessory.

For this reason, the standard specification of the electric circuit has the drawbacks of using relays with a large number of unnecessary contacts, and when changing wiring, etc., the time required for modification is large and the cost is high.

This invention eliminates the above-mentioned conventional drawbacks, and allows accessory parts such as a remote control circuit and a timer circuit to be easily assembled and connected without changing the internal wiring of the standard specification electric circuit. The present invention provides a connection device for circuit components for an air conditioner.

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

FIG. 1 is a block diagram of an electric circuit in standard specifications showing an example of the present invention, and the electric circuit has a structure in which an operation circuit 1 and a control circuit 3 are connected to each other by a connector 2.

FIG. 2 is a block diagram when the operation circuit 1 and control circuit 3 in FIG. The accessory attachment circuit 4 of this circuit is further provided with an accessory connection terminal 5, through which optional accessories such as a timer circuit, a remote control circuit, etc. can be connected.

In addition, Figure 3 shows the electrical circuit diagram of Figure 2 above.
The operation circuit 1 is composed of an operation selector switch 6, a temperature regulator 7, an abnormality indicator light 8, and an operation indicator light 9.

In addition, the accessory parts mounting circuit 4 is connected to the remote hand selector switch 10.
The control circuit 3 consists of a shorting wire 19 and a connecting terminal 20 necessary to kill the temperature regulator 7, and the control circuit 3 also includes a protection device 11.
Blower electromagnetic switch 12, defrost temperature switch 13, four-way valve switching electromagnetic valve 14, compressor electromagnetic switch 15, auxiliary heater protection device 16, and auxiliary heat electromagnetic switch 1
It is structured from 7 onwards.

When adapting the electrical circuit configured as described above to the required specifications, prepare the accessory parts separately and connect them to the accessory parts connection terminal 5 to form the required electrical circuit. It turns out.

As an example, FIG. 4 shows the case of attaching the accessory parts of the remote control circuit.

Connect the connection terminal 21 with the wire 22 across the accessory mounting terminal 5a in FIG.
By switching to the remote location, the operation selector switch 6 in the operation circuit 1 is disconnected from the accessory parts mounting circuit 4, and the operation selector switch 23 of the remote operation circuit is connected to the accessory parts mounting circuit 4. Operation switching is performed.

In addition, other remote control circuits and other accessories can be connected to the applicable terminal of the accessory connection terminal 5, and the shorting wire 19 between C and D and E and F of the connection terminal 20 is removed, and
-D and B-F are shorted. Accessory parts connection terminal 5a-6
, Seventh, remote operation is possible by sending the room thermo signal in series with the cooling/heating switching signal.

As described above, according to the device of the present invention, in order to attach an accessory to a standard electric circuit, the accessory attachment circuit 4 is connected between the operation circuit 1 and the control circuit 3, and the accessory attachment circuit 4 is connected between the operation circuit 1 and the control circuit 3. Since the method is to connect the accessory parts according to the required specifications to the accessory parts connection terminal 5 of 4, there is no need to make any changes to the standard specification electric circuit. The electrical circuit can be easily changed to the desired specifications by simply connecting to the accessory component connection terminal 5 according to the required specifications.
