Below, by one embodiment of the invention, the effect and the effect of the air conditioner of this structure is illustrated.
For action is described, be that the operation contact SW1a of the 1st mode selector switch SW1 of hypothesis Operation Mode Selection device 18 disconnects with the fixed contact SW1b of the 1st mode selector switch SW1 as primary condition, and the function that uses a teleswitch of selection.
In addition, suppose that the operation contact RY1a of relay R Y1 of outdoor load drive unit 32 and the fixed contact RY1b of relay R Y1 disconnect.
At first, as user during, then add the alternating voltage of 220V by fuse 6, at wave filter 8 from commercial AC power end with plug insertion socket.
Like this, the 220V alternating voltage of having been removed noise by wave filter 8 is added on the transformer 10, is added on the bridge diode 12 by these transformer 10 post-decompression voltages.
Then, from bridge diode 12 to the 1st diode D1 output periodic wave voltage, after being removed noise, from the 1st diode D1 to capacitor C1, C2 output periodic wave voltage, afterwards, from capacitor C1, C2 to the 1st voltage adjuster 14 output dc voltages.
Then, from 1st DC voltage of the 1st voltage adjuster 14 to the 2nd diode D2 and capacitor C3 output 12V, meanwhile, from 1st DC voltage of the 1st voltage adjuster 14 to outdoor load drive unit 32, indoor fan motor drive 34, alarm song generation drive unit 24, display unit 56 and wind direction motor drive 60 output 12V.
Then, be removed the 1st DC voltage of the 12V of noise, export to capacitor C7, C4 from the 2nd diode D2 and capacitor C3, and after the level equalization of the 1st DC voltage, to 16 outputs of the 2nd voltage adjuster.Close the 2nd DC voltage of (zero closing) device 50, indoor fan motor drive 34, resetting means 46, alarm song generating means 24, indoor temperature checkout gear the 52, the 2nd temperature-detecting device 54, temperature-detecting device 56, Operation Mode Selection device 18 and receiving system 20 output 5V like this, again to control device 2, zero phase by capacitor C5 and C6 from the 2nd voltage adjuster 16.
In this state, the user imports the method for operation to remote controller, and for example above-mentioned method of operation is a refrigeration modes.
Like this, the signal that shows the method for operation by remote controller to receiver module 22 inputs of receiving system 20.Then, the signal that shows the method for operation from receiver module 22 by resistance R 6, R8 and capacitor C10 to control device 2 inputs.
Then, export high level signal to the NOT door NOT10 of the NOT of outdoor load drive unit 32 door NOT1 and indoor fan motor drive 34 respectively from control device 2, meanwhile, the base stage to transistor T R1 is exported high level signal by the resistance R 14R10 of alarm song generating means 24.So, on relay R Y1, adding the DC voltage of 12V, operation contact RY1a and fixed contact RY1b connect, and the 220V alternating voltage of the commercial ac power source end of outside just is added on compressor 28 and the outdoor fan motor 30.Like this, compressor 28 actions, cold-producing medium begins circulation, and 30 rotations of outdoor fan motor also make the outdoor heat converter cooling.
Then, on the semiconductor relay 38 of indoor fan motor drive 34, add the 1st DC voltage of 12V, semiconductor relay 38 just is switched on, and applies voltage by the wave filter 8 of voltage supply device 4 to indoor fan motor 36, and indoor fan motor 36 just is rotated.So, room air circulate, and meanwhile in indoor heat converter, carry out heat exchange, by through in the aircooling cabinet of heat exchange.
Meanwhile, the transistor T R1 of alarm song generating means 24 is switched on repeatedly or disconnects according to the control signal (oscillator signal) of control device 2 output.When transistor T R1 is switched on, on buzzer 26, applies the DC voltage of 12V and become duty.At this moment, alarm song takes place in buzzer 26, and this alarm song has the corresponding frequency of frequency signal with control device 2 outputs.
That is to say, when the user hears the alarm song that is sent by buzzer 26, can confirm that the method for operation is selected cooling operation mode.
In addition, in carrying out air-conditioning process, when wanting to change the method for operation, the user can import the new method of operation, for example dehumidification mode of operation to remote controller.
So by the signal of remote controller to the receiver module 22 output expression methods of operation of receiving system 20, the signal of this expression method of operation is exported to control device 2 by resistance R 6, R8 and capacitor C10 from receiver module 22.Then, control device 2 is load drive unit 32 and indoor fan motor drive 34 output control signals outwards, with the operation that dehumidifies.Meanwhile, export high level signal by resistance R 14, R10 to the base stage of the transistor T R1 of alarm song generating means 24 from control device 2.Like this, compressor 28, outdoor fan motor 30 and indoor fan motor 36 are controlled,, and dehumidified indoor so that these equipment are corresponding with dehumidification mode of operation.
Meanwhile, the same with above-mentioned cooling operation mode, the DC voltage of 12V is added on the buzzer 26 of alarm song generating means 24 and sends the alarm song that has with the corresponding frequency of frequency of the control signal of control device 2 outputs.That is to say, when hearing the alarm song that takes place by buzzer 26, can confirm that the method for operation has changed dehumidification mode of operation into.
As mentioned above, adopt the present invention to have following advantage: when the method for operation changes, to send and cause The alarm song that the user notes makes the user confirm easily whether the method for operation changes, therefore, and can Control exactly the action of air conditioner, and easy to use.
In addition, since in the formation of voltage supply device, have remove the 1st diode that noise uses and The 2nd diode reduces noise contained in the voltage by voltage supply device output, therefore, Have the service behaviour that improves air conditioner, and the effect that can save power consumption, prolong user's life-span etc.
