The purpose of this utility model is to be to provide a kind of central air-conditioning air quantity remote control time switch to fill up the blank of this respect.

Of the present utility model being characterised in that: it contains: chip is the single-chip microcomputer IC2 of 78Q156BP, power supply termination rectifying and wave-filtering is with circuit output end of pressure-stabilizing and the infrared remote receiver IC1 that output links to each other with single-chip microcomputer IC2 respective end, the T2 utmost point meets the JZ4 of load motor M separately respectively, JZ3, JZ2, T1 utmost point common ground and control utmost point G and connect the strong of single-chip microcomputer IC2 through resistance respectively separately, in, weak three air quantity are regulated control end H, M, three controllable silicon BCR3 of L, BCR2 and BCR1, be connected to 14 ends and 17 of single-chip microcomputer IC2 respectively, remote control keys position selector switch DIP-2 that is serially connected with resistance separately and subscriber-coded selector switch DIP-1 between 18 ends, be connected to 6 of 13 ends of single-chip microcomputer IC2 and back parallel with one another ground connection, between 4 ends and string the remote control keys position selector switch DIP-3 of resistance is arranged, an end is successively and respectively through 10 of resistance and single-chip microcomputer IC2,11,12 ends link to each other and the other end shutoff of ground connection after resistance R 15 jointly, regulate, open and regularly use button K3, K2, K1 and the indicating circuit that links to each other with single-chip microcomputer IC2 and transfer wind and progression timing controlled to use by the classification that two groups of light emitting diodes are formed.

Evidence: it can directly replace manual central air-conditioning switch to realize air quantity remote control and the fixed cycle operator to air-conditioner.

In order in conjunction with the embodiments the utility model to be done detailed description below, show as follows employed accompanying drawing number of present specification and title brief introduction:

Fig. 1 is a central air-conditioning air quantity remote control timing switch circuit schematic diagram.

Embodiment:

Ask for an interview Fig. 1, the element of circuit and annexation thereof are as above-mentioned.Wherein, infrared remote receiver IC1 adopts TSOP1938.Controllable silicon BCR1-BCR3 adopts BT136.MI1, MK2 are respectively the modules that is connected in series diode mutually, and each is formed by eight serial connections in this example, and 2 ends of single-chip microcomputer IC2 are connected to resistance R 2 and buzzer BZ over the ground.LED 1 is a power supply indicator.Rectifying and wave-filtering and mu balanced circuit are made of MK1, MK2, voltage-stabiliser tube DZ, diode D2 to D4, capacitor C 1, C6 and resistance R 1.When controllable silicon BCR1 to BCR3 turn-offed, supply access electricity R17, R19, R21 and C7 to C9 provided, and when controllable silicon BCR1 to BCR3 conducting, but R17, R19, R21 and C7 to C9 absorb network as its crest voltage.

The combination of the subscriber-coded selector switch DIP-1 and the different position of the switch of remote control keys position selector switch DIP-2, DIP-3 can remove to control six air-conditioners by six kinds of switches and not disturb mutually in same room.When DIP-1 was downward, DIP-2, DIP-3 had three kinds of different combinations, and as being to turn-off by 1 key, 2 keys are unlatching, speed governing, and 3 keys are regularly; Can be to turn-off by 4 keys also, 5 keys be to open, speed governing, and 6 keys are regularly; When by 7 keys being turn-offs, 8 keys be open, speed governing, 9 keys are regularly the time, can corresponding other two kinds of DIP-2, the combination of DIP-3.Three kinds of other combinations when making progress, DIP-1 are arranged again.

The utility model proposes that a kind of single channel, triple bond are provided with strong H, middle M, weak L third gear air quantity is regulated and 0.5 hour to 7.5 hours scope in the central air-conditioning air quantity remote control time switch of 15 grades of progression timings.Its control indicating circuit contains: anodal hang oneself respectively successively that resistance R 7, R8, R9 link to each other respectively with 10,11,12 ends of single-chip microcomputer IC2 and negative pole connects three-step timing control indicating circuit that the LED 8 to LED6 of 18 ends forms jointly and anodally also links to each other respectively with 10,11,12,13 ends of single-chip microcomputer IC2 through resistance R 7, R8, R9, R10 separately successively, and negative pole connects 15 grades of progression timing controlled indicating circuits that the time of Displaying timer in turn of 17 ends is 0.5 hour, 1 hour, 2 hours, 4 hours four LEDs, 5 to LED2 compositions.
