[0002] The fresh air air conditioner uses a separate motor drive to achieve the operation of both the fresh air system and the ordinary air conditioning system by one motor, but it is difficult to achieve the two systems running separately or using different gears when running at the same time.

[0003] The Chinese patent application number is CN03253510.4, which discloses a single-motor double-impeller fan, but it can only realize that the motor drives the two impellers to work at the same time, and it cannot realize the gear adjustment of the impeller on either side while the other side is not affected, or the impeller on one side is turned on and the other side is closed. Its use effect is relatively simple and cannot adapt to complex application environments. Summary of the invention

[0004] Purpose of the invention: In order to overcome the above shortcomings, the purpose of the present invention is to provide a system and control method for driving air conditioning and fresh air with a single motor. The system has a simple structure, convenient operation, and reasonable design. It only uses one motor to drive two fans to work at the same time. The two fans can be operated simultaneously through a more precise gear set, and can be operated by shifting gears or running separately or in different gears.

When the telescopic rod moves into place, the drive motor starts.

[0015] It can be seen from the above technical solution that the present invention has the following beneficial effects: 1.

The adjustment gear sets 41 are installed on the synchronous output shaft 12 and the telescopic rods 42. The two telescopic rods 42 are respectively arranged on the air conditioning fan 2 and the fresh air fan 3.

[0023] Preferably, the first gear 411, the second gear 412, and the third gear 413 are sequentially arranged on the synchronous output shaft 12 and their diameters are sequentially increased, the third gear 413 is close to the body 11, the fourth gear 414, the fifth gear 415, and the sixth gear 416 are sequentially arranged on the telescopic rod 42 and their diameters are sequentially decreased, and the sixth gear 416 is close to the air conditioning fan 2 or the fresh air fan 3. The adjustment gear set 41 in this embodiment is a three-speed adjustment gear set, and the user can select the number of gears according to his own choice, and only needs to increase the number of gears.

[0024] In a preferred solution, the first gear 411, the second gear 412, and the third gear 413 can be meshed with the sixth gear 416, the fifth gear 415, and the fourth gear 414 respectively, and the above gears are all helical gears.

[0025] See also Figure 2 The telescopic rod 42 is an electrically driven telescopic rod, and the telescopic rod 42 is coaxially connected to the air conditioning fan 2 and the fresh air fan 3.

[0026] like Figure 3 As shown, it also includes a control system, which includes a main control system, a temperature and humidity sensor, an air collection sensor, and a remote control module. The temperature and humidity sensor, the air collection sensor, the remote control module, the drive motor 1 and the telescopic rod 42 are respectively connected to the main control system, the temperature and humidity sensor and the air collection sensor are installed in the use environment, and the remote control module is communicated with the remote control.

[0027] The user can choose to integrate a variety of air collection sensors. In this embodiment, the air collection sensors include formaldehyde sensors, carbon dioxide sensors and PM2.5 sensors.

[0028] like Figure 4 As shown, a control method for a system in which a single motor drives an air conditioner and fresh air includes the following steps: S1, the user selects the operation mode, including manual control mode and automatic control mode S2, the main control system issues a command, the telescopic rod 42 on the air conditioning fan 2 extends out to drive the motor 1 to start and drive the air conditioning fan 2 through the adjusting gear set 41, and the telescopic rod 42 on the fresh air fan 3 extends out to drive the motor 1 to start and drive the fresh air fan 3 through the adjusting gear set 41; S3, adjusting the extension length of the telescopic rod 42 according to the instruction issued by the main control system, so that different gears are engaged and the transmission is adjusted.

[0029] The manual control mode is specifically: the user can turn on, off and adjust the gear of the air conditioning fan 2 and the fresh air fan 3 by adjusting the function buttons on the remote control; The automatic control mode is specifically: the user selects the automatic mode on the remote control, the data collected by the temperature and humidity sensor is transmitted to the main control system, the main control system adjusts the start and stop and gear position of the air conditioning fan 2 by controlling the extended length of the telescopic rod 42, the air collection sensor transmits the data collected by it to the main control system, and the main control system adjusts the start and stop and gear position of the fresh air fan 3 by controlling the extended length of the telescopic rod 42; When shifting gears, the telescopic rod 42 moves and the driving motor 1 stops. When the telescopic rod 42 moves into position, the driving motor 1 starts.

[0030] In this embodiment, three control intervals are set in the main control system according to the number of gears. When the air-conditioning fan 2 is in the automatic control mode, when the ambient temperature is in the first temperature control interval, the main control system controls the telescopic rod 42 to extend, at which time the drive motor 1 is briefly shut down, and when the fourth gear 414 is meshed with the third gear 413, the drive motor 1 is started, and the maximum transmission ratio is obtained at this time. The air-conditioning fan 2 runs at a high speed. When the ambient temperature is in the second temperature control interval, the main control system controls the telescopic rod 42 to retract, the fifth gear 415 is meshed with the second gear, and the air-conditioning fan 2 runs at a medium speed. When the ambient temperature is in the third temperature control interval, the main control system controls the telescopic rod 42 to continue to retract, the sixth gear 416 is meshed with the first gear 411, and the air-conditioning fan 2 runs at a low speed. When the ambient temperature is lower than the third temperature control interval, the main control system controls the telescopic rod 42 to further retract, the drive motor 1 no longer transmits torque to the air-conditioning fan 2, and the air-conditioning fan 2 no longer runs. Similarly, in the automatic control mode, when the concentration of a certain indicator in the ambient air is in the first control interval, the main control system operates the fresh air fan 3 at a high speed through the gear adjustment component 4, and so on.

[0031] The air conditioning fan 2 and the fresh air fan 3 in the present invention are driven by the same driving motor 1, but the two can be operated simultaneously or independently and the gears can be adjusted independently.

[0032] The above description is only a preferred embodiment of the present invention.
