Description

Technical Field

[0001] This invention relates to the field of air conditioning control mechanism technology, specifically to an air conditioning air volume control device and control method. Background Technology

[0002] Air conditioning air volume is the amount of air delivered to a closed space or area per unit time. The larger the number, the faster the air in the whole room is exchanged for heat. The larger the number, the higher the energy efficiency ratio will be.

[0003] Existing technologies often adjust the local airflow of air conditioners by adjusting the gap between the plug and the ventilation slot. However, this method can cause some blockage to the airflow, resulting in a discrepancy between the actual airflow and the expected airflow, which affects the user experience and causes unnecessary energy consumption. Summary of the Invention

Each support block is provided with a drive worm near the two worm gears. The drive worm is meshed with the worm gears on one side, and the threads of the two drive worms are opposite.

[0015] Preferably, each of the support blocks has a snap-fit ​​groove on one side, and a number of elastic rods are vertically and symmetrically arranged at the lower end of the cover. Each of the elastic rods has a snap-fit ​​block integrally arranged on the side near the snap-fit ​​groove. Each of the snap-fit ​​blocks is inserted into a number of snap-fit ​​grooves on one side, and both sides of the snap-fit ​​blocks inserted into the snap-fit ​​grooves are inclined surfaces.

[0016] Preferably, the four guide grooves are symmetrically arranged in pairs at the upper and lower ends of the ventilation groove. The upper and lower ends of the two adjustment plates away from the swing axis are provided with sliders. The two sliders of the adjustment plates are respectively movably inserted into the upper and lower guide grooves on one side. The guide grooves are arranged in an arc shape, and the virtual central axis of the guide grooves is coaxial with the swing axis.

[0017] Preferably, both the control box and the cover are T-shaped structures. A control module box is installed on one side of the control box. A drive motor is horizontally arranged on the side of the control box near the control module box. A support box is vertically arranged on the side near the drive motor.

[0020] An air conditioning air volume adjustment method, applied to the aforementioned air conditioning air volume adjustment equipment, includes the following steps:

[0021] Step 1: Adjust the air volume as needed, input the command into the PLC controller through the communication module in the control module box, and then the controller controls the relay to start the drive motor.

[0022] Step 2: The drive motor controls the drive shaft to drive the counting disk and the drive bevel gear to rotate. Then, the driven bevel gear drives the transmission rod to rotate under the action of the drive bevel gear. Then, under the action of the drive worm gear with opposite threads, the two worm gears and the swing shaft move relative to each other.

[0023] Step 3: When the two swing shafts move relative to each other, control the two adjusting plates to open or close simultaneously in the ventilation slot. When the two adjusting plates block the ventilation slot during relative movement, there are rubber strips on the contact side of the two adjusting plates. When the two adjusting plates open the ventilation slot to the maximum extent during relative movement, the two adjusting plates are inserted into the clearance slots respectively to maintain the maximum airflow of the ventilation slot and prevent obstruction.

[0024] Step 4: When the two adjusting plates are moving, the upper and lower sliders move along the guide groove to maintain the stability of the adjusting plates, and the operation is stable and reliable.

[0025] Step 5: When the drive shaft drives the counting disk and the drive bevel gear to rotate, several top blocks on one side of the counting disk intermittently contact the balls of the push rod. When the top block contacts the balls, the balls push the push rod and the pressure rod to press the counting button, thus pressing the counting button to count and calculate the number of rotations of the counting disk.

[0026] Step Six: After the counting button provides feedback on the number of rotations of the counting disk and the drive shaft, the electrical signal is sent to the drive motor for data conversion to determine the rotation angle of the adjustment plate. This enables automatic control of the adjustment plate's stop position and intelligent adjustment and control of the airflow. Furthermore, several top blocks are set in an even number to facilitate data conversion of the counting disk's rotation angle.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] By setting two clearance components inside the control duct to accommodate the adjustment plate, the airflow will not be blocked when the control duct needs to guide the airflow to the maximum extent, thus avoiding energy loss and deviation from the actual airflow. With the cooperation of the guiding and control components, the adjustment operation is simple and the structure is stable and reliable. Then, with the assistance of the drive metering component, the opening and closing angle of the adjustment plate is automatically calculated, realizing worry-free and convenient automatic adjustment.
