The normally open contact of the second normally open and normally closed relay K5 is grounded.
Wherein, remote switch group 10 connects 12V voltage, and the coil of first normally opening relay K1, the coil of second normally opening relay K2 and the coil of third normally opening relay K3 all connect 12V voltage, and the normally open contact of third normally opening relay K3 connects 5V voltage power supply 40.
The first fan A1 and the second fan A2 are both connected with 12V voltage.
The diode group 20 includes 4 diodes, and the voltage of 12V is reduced to 10V.
The working process is as follows:
the first normally open relay K1, the second normally open relay K2 and the third normally open relay K3 are ordinary 12V normally open relays; the first normally open and normally closed relay K4 and the second normally open and normally closed relay K5 are ordinary normally open and normally closed 12V relays; the first normally open normally closed solid state relay K6 and the second normally open normally closed solid state relay K7 are normal normally open normally closed solid state relays within the remote switch group 10.
The remote control switch group 10 is used for receiving control signals, heating signals and refrigerating signals transmitted by the remote control switch, and the remote control switch group 10 is set to be in an interlocking mode, namely the heating signals and the refrigerating signals can only output one signal but cannot be output at the same time.
After the remote control switch group 10 receives the heating signal, the second normally open and normally closed solid-state relay K7 normally open contact 2 is closed, the second normally open and normally closed solid-state relay K7 normally open contact 2 is communicated with the COM port, and the normally open contact 2 outputs a low level.
The third normally opens relay K3, and the coil one end of first normally open normally closed relay K4 and second normally open normally closed relay K5 is connected with the normally open contact 2 of second normally open normally closed solid state relay K7, and after the output low level, the third is opened on relay K3's the coil and is gone up, and the normally open contact actuation of third normally open relay K3. The 5V voltage signal is used as a fan control signal S to control the fan to start natural wind.
First normally open normally closed relay K4 and the second normally open normally closed relay K5 coil go up the electricity, and first normally open normally closed relay K4 and the normal open contact of second normally open normally closed relay K5 actuation simultaneously, and first normally open normally closed relay K4 normal open contact inserts the high level, and second normally open normally closed relay K5 normal open contact inserts the low level, controls two thermoelectric devices and is in the heating mode. At this time, the two thermoelectric devices heat natural wind flowing through, so that the fan blows hot wind.
After the remote control switch group 10 receives the refrigeration signal, the normally open contact 1 of the first normally open normally closed solid state relay K6 is closed and outputs low level, the coils of the first normally open relay K1 and the second normally open relay K2 are electrified, and the normally open contacts of the first normally open relay K1 and the second normally open relay K2 are attracted.
After the normally open contact of the second normally open relay K2 is sucked, the voltage is reduced to 10V (0.5V for each diode) through 4 diodes, and the fan is controlled to open natural wind as a fan control signal S.
First normally open relay K1 normally open contact is connected with first normally open normally closed relay K4 normally closed contact 3, first normally open normally closed relay K4 normally closed contact 3 becomes the low level this moment, first normally open normally closed relay K4's COM is connected with normally closed contact 3, also become the low level, via two normally closed type temperature switch, the hot spot device in the fan is connected to one end, and second normally open normally closed relay K5's COM is connected to first thermoelectric device B1's the other end, be the high level this moment, consequently two thermoelectric devices are in the mode of refrigerating this moment. (the hot spot device in the fan works, one end is low level, the other end is high level, in the cooling mode, if the heating mode is needed, the high/low level at the two ends, the high level at the one end and the low level at the other end need to be exchanged), at this moment, the thermoelectric device cools the natural wind flowing through, so that the cold wind is blown out by the fan.
In the control circuit, a temperature switch is matched to protect the thermoelectric device, when the working temperature of the thermoelectric device reaches 85 ℃, the control circuit controls the thermoelectric device to stop working, and the fan starts a natural wind mode; when the internal temperature of the thermoelectric device is restored to 65 ℃, the control circuit controls the thermoelectric device to work again, and the cooling/heating mode is kept.
The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
