According to the ambient temperature and the needs of users, the user can select the working mode of the four-way valve through a remote control board, and can switch the outdoor unit and the indoor unit between the evaporation and condensation functions. When the indoor unit is in the evaporation state, the air conditioner provides a cooling mode for the room, and when the indoor unit is in the condensation state, the air conditioner provides a heating mode for the room.
[0003] Generally, an air conditioner is equipped with a remote control board, and the user can control the temperature adjustment and the device to be in the on or off mode through the remote control board. Since the air conditioners used in office areas and other places have a relatively large power, when the personnel in the office adjust the cooling or heating temperature relatively low or high, it will cause waste of electric energy; in addition, when the air conditioner in the corresponding area is turned on and the relevant personnel do not turn off the power after work, it will also bring unnecessary waste of electric energy. In summary, it is very necessary to provide an air conditioner controller device that can set the maximum and minimum set temperatures and can automatically turn off the compressor power supply when there is no one.

[0014] Figure 1 、 2As shown in the figure, an air conditioner controller device includes a power supply module W1, and also has a temperature control mechanism 1, a temperature control circuit 2, and a personnel detection circuit 3. There are two sets of the temperature control mechanism 1, and each set of the temperature control mechanism includes a motor reduction device M (M1) and an adjustable temperature switch RP1 (RP2). The lower end of the output shaft of the motor reduction device M (M1) is welded to the middle upper end of the adjustment handle of the adjustable temperature switch RP1 (RP2). The power supply module W1, the temperature control circuit 2, and the personnel detection circuit 3 are installed on the circuit board in the component box 4. There are rectangular openings 41 at both ends of the front side of the component box 4. The upper ends of the housings of the two sets of motor reduction mechanisms M (M1) are respectively installed inside the left and right sides of the upper front end of the component box 4, and the two sets of adjustable temperature switches RP1 (RP2) are installed inside the left and right sides of the lower front end of the component box 4.
[0015] Figure 1 、 2 As shown in the figure, the front side ends of the adjustment disks of the two sets of adjustable temperature switches RP1 (RP2) and the temperature numbers printed on the adjustment disks are located outside the outer side ends of the two openings 41, and the outer diameter of the front side end of the adjustment disk is smaller than the horizontal length of the opening 41. The temperature control circuit includes a key power switch S, S1, S2, S3, relays K, K1, K5, K6, K2, a resistor R1, and a triode Q1 connected by circuit board wiring. One end of the four key power switches S, S1, S2, S3 (the keyholes are located outside multiple openings at the front end of the component box) is connected to the positive power input terminal of the first relay K2 and the positive control power input terminals of the second relay K, the third relay K1, the fourth relay K5, and the fifth relay K6. The other ends of the four key power switches S, S1, S2, S3 are respectively connected to the positive power input terminals of the second relay K and the third relay K1, the fourth relay K5, and the fifth relay K6. The negative power input terminals and the negative control power input terminals of the second relay K, the third relay K1, the fourth relay K5, and the fifth relay K6 are connected to the emitter of the triode Q1. The collector of the triode Q1 is connected to the negative power input terminal of the first relay K2. One end of the resistor R1 is connected to the base of the triode Q1. The personnel detection circuit includes relays K3 and K4, a time control switch W3, and a microwave detection module W2 connected by circuit board wiring. The detection head of the microwave detection module W2 is located outside the middle opening at the front end of the component box. The positive power input terminal 1 of the microwave detection module W2 is connected to the control power input terminal of the first relay K3. The positive power output terminal 3 of the microwave detection module W2 is connected to the positive power input terminal of the first relay K3. The negative power input terminal 2 of the microwave detection module W2 is connected to the negative power input terminal of the first relay K3 and the negative power input terminal 2 of the time control switch W3. The normally closed contact terminal of the first relay K3 is connected to the positive power input terminal 1 of the time control switch W3. The power output terminals 3 and 4 of the time control switch W3 are respectively connected to both ends of the power input of the second relay K4.
[0016] Figure 1 、 2 As shown, the power input terminals 1 and 2 of the power supply module W1, the control power input terminal of the relay K2, and the two poles of the AC 220V power supply are respectively connected by wires. The power output terminals 3 and 4 of the power supply module W1, the power input terminal of the temperature control circuit, the positive power input terminal of the relay K2, and the emitter of the triode Q1, and the power input terminals 1 and 2 of the microwave detection module W2 of the personnel detection circuit are respectively connected by wires. The signal output terminal of the temperature control circuit, the two normally closed contact terminals of the relay K2, and the two control power input terminals of the relay K4 of the personnel detection circuit are connected by wires. The control power output terminal of the personnel detection circuit, the two normally closed contact terminals of the relay K4, and the power input terminal of the compressor W of the air conditioner body are connected by wires. The two normally open contact terminals of the power output terminals of the two temperature control circuits, the relays K, K1, K5, and K6, and the positive and negative and negative-positive power input terminals of the motor reduction devices M and M1 are respectively connected by wires. The two signal terminals of the adjustable temperature switches RP1 and RP2 are connected by wires between the two signal input terminals of the temperature control circuit, the positive power input terminal of the relay K2, and the emitter of the triode Q1.
[0017] Figure 1 、 2 As shown, usually, the AC 220V power supply enters the power input terminal of the air conditioner body W through the control power input terminal and the normally closed contact terminal of the relay K2 and the control power input terminal and the normally closed contact terminal of the relay K4. In this way, the indoor personnel can control the operation of the air conditioner body (including controlling the output of cold air or hot air) through the remote control switch supporting the air conditioner. After the AC 220V power supply enters the power input terminal of the power supply module W1, the stable DC 12V power supply output from the 3rd and 4th pins of the power supply module W1 enters the power input terminals of the two temperature control mechanisms, the temperature control circuit, and the personnel detection circuit. Before application, relevant management personnel can control the set temperature of the adjustable temperature switches RP1 and RP2 through the keys carried with them. Specifically, after the management personnel use the key to turn on the key power switch S or the key power switch S1, or the power switches S2 and S3, the relay K or K1
[0018] Alternatively, K5 or K6 will be energized to attract, and its control power input terminal and normally open contact terminal will be closed. In this way, the positive and negative or negative and positive power input terminals of the motor speed reduction device M or M1 will be energized, and the power output shaft of the motor speed reduction device M or M1 will drive the adjusting handle of the adjustable temperature switch RP1 or RP2 to rotate counterclockwise or clockwise. When the adjustable temperature switch RP1 or RP2 reaches the set indoor control temperature, the relevant personnel turn off the key power switch S or the key power switch S1, or alternatively, the power switches S2, S3. In this way, the motor speed reduction device M or M1 will no longer drive the handles of the adjustable temperature switches RP1 and RP2 to rotate. (The temperature of the adjustable temperature switches RP1 or RP2 is controlled by the key power switch method mainly to prevent other people in the office from manually adjusting the handles of the adjustable temperature switches RP1 or RP2 to set the temperature too low or too high).
[0019] Figure 1 , 2 As shown in 2 , when the indoor temperature is lower than the temperature set by the adjustable temperature switch RP1 (in summer, for example, lower than 28 °C), or higher than the temperature set by the adjustable temperature switch RP2 (in winter, for example, higher than 20 °C), the internal contacts of the adjustable temperature switch RP1 or RP2 are open. In this way, the relay K2 will not be energized to attract, and its control power input terminal and normally closed contact terminal will continue to be closed. Then, the compressor of the air conditioner W will continue to be energized, and the air conditioner will continue to be in the working refrigeration mode (the 220V AC power supply enters the power input terminal of the compressor W through the control power input terminal and two normally closed contact terminals of the relay K2, and the two control power input terminals and two normally closed contact terminals of the relay K4). When the indoor temperature is higher than the temperature set by the adjustable temperature switch RP1 (in summer, for example, higher than 28 °C), or lower than the temperature set by the adjustable temperature switch RP2 (in winter, for example, lower than 20 °C), the internal contacts of the adjustable temperature switch RP1 or RP2 are closed. In this way, the 12V power supply will enter the base of the triode Q1 after being stepped down and current-limited by the resistor R2. The triode Q1 conducts, and the collector outputs a low level and enters the negative power input terminal of the relay K2. The relay K2 is energized to attract, and its control power input terminal and normally closed contact terminal are open. The subsequent compressor will no longer be energized to work. Through the above, this new type can disconnect the compressor power supply when the indoor temperature is at the temperature set by the relevant management personnel.
[0020] Figure 1 , 2As shown, when there are people in the room, the 3rd pin of the microwave detection module W2 outputs a high level. In this way, the relay K3 is energized and its control power input terminal and normally closed contact terminal are open. The 12V power supply will not enter the power input terminal of the time control switch W3 through the control power input terminal and normally closed contact terminal of the relay K2. The relay K4 continues to be de-energized and its control power input terminal and normally closed contact terminal are closed. In this way, when there is someone in the room, the compressor W of the air conditioner will be normally energized and work. When there are no people in the room, the 3rd pin of the microwave detection module W2 stops outputting a high level. The relay K3 is de-energized and no longer attracts, and its control power input terminal and normally closed contact terminal are closed. The 12V power supply will enter the power input terminal of the time control switch W3 through the control power input terminal and normally closed contact terminal of the relay K2. After the time control switch W3 is energized and works, its 3rd and 4th pins output power at intervals of a period of time (such as 10 minutes) and enter the power input terminal of the relay K4. The relay K4 is energized and its control power input terminal and normally closed contact terminal are open. The compressor W is no longer energized and works. Until someone enters the room again later, the 3rd pin of the microwave detection module W2 outputs a high level again and the relay K3 is de-energized again. The power input terminal of the compressor W will be energized again and the air conditioner body works normally. Through the above, the relevant staff of this new type can control the set temperature of the adjustable temperature switch through the key power switch carried with them. In this way, when the temperature set by other people using the air conditioner remote control board is higher or lower than the set temperature, it can automatically control the compressor of the air conditioner to be temporarily de-energized, and when there are no people in the room, after a period of time, it can automatically turn off the total power switch of the compressor of the air conditioner, thus achieving the purpose of energy saving (the working mode of controlling the compressor of this new type does not control the power on or off of the total power supply of the air conditioner because if only the total power supply of the air conditioner is controlled, then after the total power input terminal of the air conditioner is powered on, the user still needs to use the remote control board to remotely turn on or adjust the temperature, which has an adverse impact on the actual normal use; the power of the air conditioner compressor W is relatively large, so controlling its working mode can achieve the purpose of power saving; the compressor W of the air conditioner is controlled to be de-energized every 10 minutes because when people leave the office area, they may return to the office within a short time. Therefore, a delay of 10 minutes or more can ensure that when the relevant personnel return to the room, the temperature will not take a long time to return to the set value, bringing discomfort to them).The power supply module W1 is a finished product of an AC 220V to DC 12V power supply module; the relays K, K1, K2, K3, K4, K5, and K6 are DC 12V relays; the resistance value of the resistor R1 is 4K; the model of the triode Q1 is 9013 (NPN triode); the time control switch W3 is a time controller module of model KG316T, which has two power input terminals and two power output terminals. By adjusting its own seven setting buttons, the time of the two power outputs can be set; the adjustable temperature switch RP1 is an adjustable normally open contact temperature switch of the Korean Rainbow brand with a temperature range of 0 - 80°C (liquid expansion type adjustable normally open contact temperature switch, and the temperature sensing head is located at the outer side end of the component box); the adjustable temperature switch RP2 is an adjustable normally closed contact temperature switch of the Korean Rainbow brand with a temperature range of 0 - 80°C (liquid expansion type adjustable normally closed contact temperature switch, and the temperature sensing head is located at the outer side end of the component box); the motor reduction devices M and M1 are coaxial motor gear reducers with a working power of DC 12V and a power of 10W, and the power output shaft rotates 6 revolutions per minute; the microwave detection module W2 is a finished product of a microwave radar induction switch of model TDL - 2022WB, which has two power input terminals and one signal output terminal. When human activity information is detected within a 10 - meter circumference, its signal output terminal will output a high level (it has a distance adjustment knob to adjust the detection distance, and in this embodiment, it is adjusted to about 6 meters).
