In the controller 600 provided by the present invention, the first power supply terminal 102 of the control component is connected to the power supply 900, the heating control terminal 104 of the control component is connected to one end of the temperature control component 200, and the other end of the temperature control component 200 is connected to the fan 400, so that when the temperature control component 200 is closed, the power supply to the fan 400 is realized.
Because the temperature control part 200 is arranged on the heat exchanger 500, the temperature control part 200 can be opened or closed according to the temperature of the heat exchanger 500, and further when the temperature of the heat exchanger 500 is lower than a threshold value, the fan 400 is thrown to convey air indoors, and further the influence of the air with lower temperature on the indoor is reduced, and the comfort level of an indoor user is improved. And the first control component 100 and the temperature control component 200 realize the cold air prevention of the air conditioner, simplify the structure of the controller 600, and reduce the cost of the controller 600, so that the air conditioner is more suitable for the user groups which have high requirements on the cost of the controller, low requirements on intellectualization and need the functions of heating and cold air prevention.
Specifically, when the user sets the air conditioner to the heating mode, the temperature control unit 200 is turned off when the temperature of the heat exchanger 500 is low, that is, when the temperature of the heat exchanger 500 is lower than the threshold value, so that the fan 400 stops operating and does not supply air to the room. When heat exchanger 500's temperature is higher, when heat exchanger 500's temperature is higher than the threshold value promptly, temperature control part 200 is closed, make power 900 supply power for fan 400, fan 400 begins to rotate and to indoor air supply, because indoor heat exchanger 500's temperature is higher this moment, so fan 400 no longer need send into the lower air of temperature earlier to the room, but directly send into the higher air of temperature to the room, and then reduce the lower air of temperature to indoor influence, promote indoor user's comfort level, realize preventing that the air conditioner from blowing cold wind to the room. The temperature threshold of the heat exchanger 500 may be determined empirically.
When the air conditioner works, the first power supply end 102 is connected with the power supply 900, the power supply 900 provides commercial power to the fan 400 through the first control component 100, the commercial power does not need to be converted into a control signal, the driving and the control of the fan 400 can be realized, the power supply conversion module 810 is saved, the structure of the controller 600 is further simplified, and the cost of the controller 600 is reduced.

In this embodiment, the second control unit 300 is connected in series between the first control unit 100 and the fan 400, the second power supply end 302 of the second control unit 300 is connected to the first control unit 100, the plurality of gear control ends are in one-to-one correspondence with the plurality of gear control lines of the fan 400, and when the first control unit 100 and the temperature control unit 200 achieve the purpose of preventing the air conditioner from blowing cold air indoors, the second control unit 300 can control the rotation speed of the fan 400, so that a user can select the air intake of the air conditioner according to indoor experience, and the comfort of the user is further improved.
The second control unit 300 can control the second power supply terminal 302 to be connected to a gear control line of the fan 400 according to the user's requirement, so as to control the rotation speed of the fan 400.
Example three:
the present embodiment provides a controller 600, and in addition to the technical features of the above-described embodiments, the present embodiment further includes the following technical features.
As shown in fig. 1 and 2, the first control part 100 further includes a cooling control terminal 106, and the cooling control terminal 106 is connected to the second power supply terminal 302.
In this embodiment, the cooling control terminal 106 of the first control part 100 is connected to the second power supply terminal 302 of the second control part 300. When the user sets the air conditioner to the cooling mode, the first control component 100 can skip the temperature control component 200 to supply power to the fan 400, so that disconnection of the temperature control component 200 due to the fact that the temperature of the heat exchanger 500 is lower than the threshold value is avoided, the fan 400 is stopped, and normal operation of the air conditioner in the cooling mode is guaranteed.
Example four:

The commercial power enters the second control part 300 through the first power supply end 102 and the refrigeration control end 106, so that the temperature control part 200 cannot control the start and stop of the fan 400, the first control part 100 can skip the temperature control part 200 to supply power to the fan 400, the phenomenon that the temperature control part 200 is disconnected due to the fact that the temperature of the heat exchanger 500 is lower than a threshold value is avoided, the fan 400 is stopped, and normal operation of the air conditioner in the refrigeration mode is guaranteed.
Since the control of the blower 400 can be realized by changing the position of the first slider 110, the user can manually toggle the slider. When the ambient temperature is lower, the user sets the air conditioner to the heating mode, and stirs the first slider 110 to the first position this moment for the start-stop of the steerable fan 400 of temperature control unit 200 is stopped, and then realizes preventing cold wind. When the ambient temperature is higher, the user sets the air conditioner to the refrigeration mode, stirs the first slider 110 to the second position this moment for the temperature control part 200 can't control opening of fan 400 and stop, and then realizes the refrigeration operation of air conditioner.
As shown in fig. 5, when the air conditioner is in a standby state, the first slider 110 moves to the third position, and the first slider 110 is not connected to the cooling control terminal 106 or the heating control terminal 104.
Because the user can manually stir the sliding block, the controller 600 does not need to be provided with an additional control panel 808 and an additional display screen 804, the structure of the control component is further simplified, and the cost of the control component is reduced.
