The existing air conditioner temperature control method is that indoor users control it through a remote control panel. When it is used in offices or other public places, because the relevant managers (such as company managers) cannot set the minimum temperature, when the indoor personnel use the remote control panel to control the temperature of the corresponding area to be too low in summer, it will cause unnecessary waste of electricity (if the relevant managers keep the air conditioner remote control panel, it will cause inconvenience to the indoor personnel to turn on and off the air conditioner, and when there are many management scopes and air conditioner remote control panels, it will also cause inconvenience to the relevant managers). In summary, it is very necessary to provide an energy-saving device that allows relevant personnel to pre-set the minimum temperature of the air conditioner. Utility Model Content

The display control circuit includes an electrically connected adjustable resistor AR1, a liquid crystal voltage display meter V, and a relay K, one end of the adjustable resistor AR1 is connected to the positive power input terminal of the voltage display meter V, and the other end of the adjustable resistor AR1 is connected to the negative power input terminal of the voltage display meter V and the negative power input terminal of the relay K. The display interface of the voltage display meter V and the lock holes of the key power switches S1 and S2 are respectively located outside the three openings at the front outer side of the shell of the panel power socket CT. The key power switches S1 and S2 have two power input terminals 1 and 2, and two power output terminals 3 and 4. The keys of the wireless remote control panel A3 and the key power switches S1 and S2 (shared with one key) are kept by the relevant management personnel (for example, they can be hung on a key chain). The management personnel of the relevant area can control the opening and closing of the new key power switches S1 and S2 of all the separate indoor air conditioners by the key, and can control the working mode of the new wireless receiving circuit of all the separate indoor air conditioners by the wireless remote control panel A3.

[0017] Figure 1 , 2 As shown in 3, the power input terminals 1 and 2 of the power module A1, the two control power input terminals of the display control circuit relay K and the two poles of the AC 220V power supply are connected by wires, and the two normally closed contact terminals of the control power output terminal relay K of the display control circuit and the two wiring posts of the panel power socket CZ are connected by wires. The power input terminal of the wireless receiving circuit, the 1 and 2 pins of the wireless receiving circuit module A2, the other end of the power input terminal of the display control circuit adjustable resistor R1 (pin 4 of the power module A1), the power input terminals 1 and 2 pins of the two key power switches S1 and S2 and the power output terminals 3 and 4 pins of the power module A1 are connected by wires. The two normally open contact terminals of the two control power output terminals of the wireless receiving circuit relay K1 and K2, the 3 and 4 pins of the two key power switches S1 and S2 and the positive and negative and negative and positive power input terminals of the motor reduction mechanism M1 are connected by wires. The two wiring terminals of the adjustable resistor RP1 and one end of the adjustable resistor AR1 and the 3 pin of the power module A1 are connected by wires. The two terminals of the temperature control switch W, the 3rd foot of the power module A1 and the positive power input terminal of the relay K are connected via wires respectively.

[0018] Figure 1 , 2As shown in Figures 3 and 4, the present invention is mainly used for the temperature management of the cooling mode of the air conditioner in the public area of ​​the office, etc. (for example, in the southern region, the temperature is relatively high in winter, and the chance of turning on the air conditioner is relatively low, so the present application is mainly used for the management of the cooling temperature setting. Correspondingly, adding a set of the present invention can also manage the heating temperature setting of the relevant area. Specifically, the present invention is used for temperature management in summer, and the power supply of the present invention is disconnected in winter, and another set of the present invention is connected to manage the indoor heating mode of the air conditioner). After turning on the main power switch, the power module A1 and the relay K control power input end are energized, and the 220V power supply enters the power input end of the panel power socket CT through the relay K control power input end and the two normally closed contact ends. In this way, the air conditioner with the power plug inserted into the jack of the panel power socket CT will be powered and work, and the indoor personnel can conveniently control the working mode of the air conditioner and the cooling or heating temperature through the remote control panel of the air conditioner. After the power module A1 is energized, its 3 and 4 pins output a stable DC 12V power supply that enters the wireless receiving circuit, the display control circuit, and the power input end of the two key power switches S1 and S2. In order to prevent the indoor personnel at the corresponding position from setting the output temperature of the air conditioner too low, the relevant management personnel can set the minimum output temperature of the air conditioner through the key switch method or the separate wireless remote control panel method (for example, it cannot be lower than 28℃ in summer); setting the temperature through two methods is to prevent extreme cases, when the wireless remote control panel A3 is out of power or damaged, the relevant personnel can also set the temperature threshold through the power switches S1 and S2 (the wireless remote control method does not need to approach the panel power socket and is operated with the key power switch, which is relatively more convenient to use). After the relevant management personnel use the key to turn on the key power switch S1 or S2, the 1st and 2nd feet and the 3rd and 4th feet of the power switch S1 or S2 are connected respectively, so that the positive and negative or negative positive two-pole power input terminal of the motor reduction mechanism M1 will be energized, and then adjust the temperature control switch W to set the minimum output temperature of the air conditioner (the working principle will be described in detail later). After turning off the key power switch S1 or S2, the positive and negative or negative positive two-pole power input terminal of the motor reduction mechanism M1 will lose power.After the relevant manager presses the first transmitting button D1 or the second transmitting button D2 of the wireless remote control panel A3 with his finger, the wireless remote control panel A3 will transmit the first or second wireless closing signal. After the wireless receiving circuit module A2 receives the first or second wireless closing signal, its 3rd or 4th foot will output a high level and enter the positive power input terminal of the relay K1 or K2 respectively. In this way, the relay K1 or K2 will be energized to attract its control power input terminal and the normally open contact terminal to close, and the positive and negative or negative and positive power input terminals of the motor reduction mechanism M1 will be energized, and then Adjust the temperature control switch W to set the lowest output temperature of the air conditioner; after the relevant manager presses the first transmitting button D1 or the second transmitting button D2 of the wireless remote control panel A3 with his finger again, the wireless remote control panel A3 will transmit the first or second wireless open circuit signal, and the wireless receiving circuit module A2 will stop outputting a high level at its 3rd or 4th pin after receiving the first or second wireless closed signal. In this way, the relay K1 or K2 loses power and no longer attracts its control power input terminal and the normally open contact terminal, and the positive and negative or negative and positive power input terminals of the motor reduction mechanism M1 will lose power.

[0019] Figure 1 , 2As shown in 3, after the relevant management personnel control the positive and negative or negative and positive power input terminals of the motor reduction mechanism M1 through the key power switch or the wireless remote control panel to obtain power, the positive and negative power input terminals of the motor reduction mechanism M1 are energized, and its rotating shaft drives the driving wheel 31 and the handle of the temperature control switch W to rotate counterclockwise, so that the temperature of the temperature control switch W is set to a relatively low level (the relevant staff adjusts it in combination with the voltage display meter and the displayed numbers, and turns off the power of the motor reduction mechanism after the adjustment is in place); after the negative and positive power input terminals of the motor reduction mechanism M1 are energized, its rotating shaft drives the driving wheel 31 and the handle of the temperature control switch W to rotate clockwise, so that the temperature of the temperature control switch W is set to a relatively high level (the relevant staff adjusts it in combination with the numbers displayed on the voltage display meter, and turns off the power of the motor reduction mechanism after the adjustment is in place). In the present invention, when the staff adjusts the temperature of the temperature control switch, the driving wheel rotates counterclockwise or clockwise, and the driving wheel 31 drives the driven rubber wheel 32 to rotate clockwise or counterclockwise. In this way, the resistance of the adjustable resistor RP1 will increase or decrease accordingly. In actual circumstances, when the temperature of the temperature control switch W is adjusted to a relatively low temperature, the resistance value of the adjustable resistor RP1 is relatively large, and the voltage division between the adjustable resistor RP1 and the adjustable resistor AR1 is relatively large. In this way, the power supply voltage entering the voltage display table V is relatively low, and the voltage number displayed on the voltage display table V is relatively low (for example, the displayed voltage number is 02.40, which means that the set temperature is 24°C); when the temperature of the temperature control switch W is adjusted to a relatively high temperature, the resistance value of the adjustable resistor RP1 is relatively small, and the voltage division between the adjustable resistor RP1 and the adjustable resistor AR1 is relatively small. In this way, the power supply voltage entering the voltage display table V is relatively high, and the voltage number displayed on the voltage display table V is relatively high (for example, the displayed voltage number is 02.80, which means that the set temperature is 28°C). Through the above, when the relevant management personnel adjust the set temperature, they can combine the voltage display table V to display the voltage digital representing the temperature, and adjust the temperature of the air conditioner. After the temperature is adjusted, the power supply of the motor reduction mechanism is turned off. In actual situations, after the temperature control switch W sets the temperature, when the air conditioner cools the environment below a certain temperature (for example, the indoor ambient temperature is higher than 28°C), the two contacts inside the temperature control switch W are open, so that the relay K will not be energized and the panel power socket CZ continues to output power to the power input end of the air conditioner, and the air conditioner continues to work. After reaching the set temperature of the temperature control switch W, when the air conditioner cools the environment above a certain temperature (for example, the indoor ambient temperature is lower than 28°C), the two contacts inside the temperature control switch W are closed, and then the relay K is energized and its control power input end and the normally closed contact end are open, and the panel power socket CZ no longer outputs power to the power input end of the air conditioner, and the air conditioner loses power and no longer works.

[0020] Figure 1 , 2As shown in Figure 3, through the above, in the present invention, the relevant management personnel can set the lowest temperature of the air conditioner through the temperature adjustment device, display control circuit, etc. by means of a key switch or a separate wireless remote control panel. When the temperature set by the personnel in the corresponding area through the air conditioner remote control panel is too low, the air conditioner can be controlled to lose power and not work, which serves as a reminder to the personnel in the relevant area (the indoor personnel need to wait until the indoor temperature is relatively high before restarting the machine), thereby relatively achieving the purpose of energy saving. The relays K1, K2, and K are of DC12V; the power module A1 is a finished product of a 220V AC to 12V DC switching power module; the wireless remote control panel A3 and the wireless receiving circuit module A2 are finished products of a wireless transmitting and receiving circuit module of model FW50, and the wireless transmission and reception distance is 50 meters (completely consistent with the structure and function of the existing wireless transmitting and receiving circuit modules for vehicle and warehouse door control); the voltage display meter V is a four-digit liquid crystal voltage display meter with a range of 12V; the motor reduction mechanism M1 is a finished product of a small coaxial motor gear reducer with a working voltage of 12V DC and a power of 10W, and a speed of 5 revolutions per minute; the adjustable resistor RP1 has a resistance of 47K; the temperature control switch W is a finished product of a Korean Rainbow brand 0-80℃ normally closed contact continuously adjustable temperature control switch, and its temperature sensing head is located on the outside of the front end of the panel socket (it should be noted that this When the new type is used for indoor heating temperature control, the temperature control switch W needs to use a continuously adjustable temperature control switch with normally open contacts, and the internal contacts are closed when the higher temperature is set, and the internal contacts are open when the higher temperature is set); the resistance value of the adjustable resistor AR1 is 100K (when the new type is finalized for production, it is necessary to adjust and determine the resistance value of the adjustable resistor AR1. Specifically, in a room with a known temperature, manually adjust the high or low resistance value of the adjustable resistor AR1 (the larger the resistance value, the greater the voltage divider between the adjustable resistor RP1, and vice versa). When the voltage number displayed on the voltage display table V (for example, 02.60) is just consistent with the actual temperature (26°C), the purpose of resistance setting is achieved. Before mass production, the resistance value of the current adjustable resistor AR1 can be measured with a resistance meter, and a fixed resistor with the same resistance value can be used instead in actual production).
