[0038] The full name of the air valve is the air volume regulating valve. The air volume regulating valve is an indispensable central air-conditioning terminal accessory in the ventilation, air conditioning and air purification projects of industrial plants and civil buildings. It is generally used in air-conditioning and ventilation system pipes to adjust the air volume of the branch pipe. It can also be used for the mixing adjustment of fresh air and return air. At present, the conventional system unit controls the opening and closing of the air duct through the air valve, and the external air directly enters the air duct after passing through the air valve. After the air valve is closed, there is a risk of some mosquitoes entering the air duct, thereby breeding bacteria in the air duct. In addition, the air valve and filter of the existing unit are set independently, which occupies a large installation space and increases the installation steps of the unit parts.

[0039] In order to solve the technical problem that the existing air valve and filter of the air conditioner set are independently set to reduce the use effect of the air conditioner, the main purpose of the present application is to combine the air valve with the filter. On the one hand, the present application provides a wind control device 200, the wind control device 200 is equipped with a blade group 120, the blade group 120 includes a plurality of blades 121, and the plurality of blades 121 are rotatably mounted on the main body 110. At the air duct, multiple blades 121 can be rotated to form an overlapping state in sequence, thereby closing the air duct. Multiple blades 121 can also be rotated to open, and the gap between two adjacent blades 121 forms an air outlet. In the present application, a filter element 140 is set between two adjacent blades 121. When the blade 121 is rotated to open, the filter element 140 is driven to expand, and the filter element 140 can filter the air flow flowing through the air outlet. When the blade 121 is rotated to close, the filter element 140 is driven to retract, so that the wind control device 200 closes the air duct, combines air volume adjustment with air filtration, and reduces the installation space of the unit. At the same time, the filter element 140 can prevent mosquitoes from entering the air duct when the air duct is open, and prevent bacteria from growing in the air duct. On the other hand, the present application provides an air-conditioning unit, which is equipped with the above-mentioned wind control device 200. The wind control device 200 has air volume adjustment and filtering functions, which can not only prevent mosquitoes from entering the air duct to breed bacteria, but also cancel the original filter, reduce the volume of the unit, make full use of the installation space of the unit, and reduce the installation process of the unit.

[0040] Figure 1 is a schematic structural diagram of an air conditioning unit according to an exemplary embodiment. Figure 2 is a schematic diagram showing a wind control device 200 according to an exemplary embodiment. Figure 3 is a schematic structural diagram of a wind control device 200 from another perspective according to an exemplary embodiment. Figure 4 According to an exemplary embodiment, Figure 3 AA section diagram, Figure 5 According to an exemplary embodiment, Figure 4 A partial enlarged schematic diagram is shown in the figure.

[0041] An embodiment of the present application provides an air-conditioning unit, which includes a unit case 100. A water receiving box can be arranged in the unit case 100. A water outlet is provided at the bottom of the water receiving box. The water outlet is connected to a water pipe 300. When the water receiving box is arranged in a negative pressure area of ​​the air-conditioning unit, the water pipe 300 can be connected to a water pump after being led out of the unit case 100. The water pump is used to pump condensed water collected in the water receiving box out of the unit case 100. On this basis, the condensed water can be led to a demand location through the water pipe 300 to improve the utilization efficiency of water resources.

[0042] The unit casing 100 is provided with an air inlet, and the wind control device 200 is installed at the air inlet. The wind control device 200 includes a main body 110, a blade group 120, a driving member and a filter member 140. The main body 110 is provided with an air duct, and the air duct is connected to the air inlet of the unit casing 100.

[0043] This application Figure 1 In the example, the unit case 100 is approximately a rectangular parallelepiped, and the cross-section of the air duct is rectangular. The blade group 120 includes a plurality of blades 121, and the plurality of blades 121 are rotatably mounted on the air duct of the main body 110, and the axial direction of the rotation axis of the blade 121 is perpendicular to the extension direction of the air duct, and the axial direction of the rotation axis of the blade 121 is the same as the length direction of the blade 121. In the present application, the plurality of blades 121 can be rotated to form an overlapping state in sequence, thereby closing the air duct, and the plurality of blades 121 can also be rotated to open, and the gap between two adjacent blades 121 forms an air outlet.

[0044] The driving member is installed on the main body 110, and the driving member is connected to each blade 121 in a transmission manner. In a specific embodiment, the blade 121 is rotatably connected to the main body 110 through a driving shaft, and the driving shaft extends to the outside of the main body 110. A driven wheel is installed on the part of each driving shaft located outside the main body 110, that is, each blade 121 is connected to a driven wheel through a driving shaft, and the driven wheels of each blade 121 in the blade group 120 are meshed and connected. The driving member can select a driving motor, and the driving shaft of the driving motor is connected to a driving wheel. The driving wheel can mesh with one of the driven wheels, so that the driving motor drives each blade 121 to rotate open or rotate closed at the same time through the gear set.

[0045] In some embodiments, those skilled in the art may also change the blade 121 to manual control, as described in the present application. Figure 2 In the example, a hand valve 130 is rotatably mounted on the outer side of the main body 110, and the hand valve 130 is connected to a driving wheel, and the driving wheel is meshed and connected with a driven wheel of one of the blades 121. The driving wheel and the driven wheel, or each driven wheel, can be connected by a belt drive.

[0046] like Figure 4 As shown, a filter 140 is arranged between two adjacent blades 121. When the blades 121 rotate to open, the filter 140 is driven to expand. The filter 140 can filter the airflow passing through the air outlet. When the blades 121 rotate to close, the filter 140 is driven to fold, so that the wind control device 200 closes the air duct.

[0047] In the present application, the filter element 140 is combined with the blade 121, so that the wind control device 200 has the functions of air volume regulation and air filtering. After the wind control device 200 is installed in the air conditioning unit, the installation space of the unit can be reduced. At the same time, the filter element 140 can also prevent mosquitoes from entering the air duct when the air duct is open, preventing the breeding of bacteria.

[0048] The filter element 140 has a filter screen 143 and two rollers, the filter screen 143 is wound on the rollers, for the convenience of explanation, the present application defines the two rollers as a first roller 141 and a second roller 142, respectively, the blade 121 is provided with a connecting portion, the first roller 141 and the second roller 142 are respectively rotatably installed on the connecting portions of two adjacent blades 121, the first roller 141 and / or the second roller 142 are provided with a recovery component, the recovery component is used to drive the first roller 141 and / or the second roller 142 to rotate when the blade 121 rotates to close the air duct, so that the filter screen 143 is wound and recovered on the first roller 141 and / or the second roller 142.

[0049] In a specific embodiment, refer to Figure 5 As shown, according to the placement state of the air conditioner unit when in use and the installation state of the wind control device 200, the upper roller of the two rollers of the filter element 140 is defined as the first roller 141, and the relatively lower roller is defined as the second roller 142. The two ends of the blade 121 in the length direction are respectively provided with connecting parts, and the connecting parts are hook-shaped. The first roller 141 rotates to connect the two connecting parts of the upper blade 121 of the two adjacent blades 121, and the second roller 142 rotates to connect the two connecting parts of the lower blade 121 of the two adjacent blades 121. The filter 143 is wound on the roller between the two connecting parts. The recovery part includes a torsion part installed on the first roller 141 and the second roller 142, that is, one torsion end of the torsion part is connected to the roller, and the other torsion end is connected to the blade 121. When the blade 121 rotates to open, the filter 143 stretches and drives the roller to rotate. The torsion part is locally deformed by the torsion. When the blade 121 rotates to close, the torsion part drives the roller to rotate and roll up the filter 143. The torsion part can use a torsion spring.

[0050] In some embodiments, a torsion spring may be installed only on the first roller 141 or the second roller 142 , so that the filter screen 143 is wound around the first roller 141 or the second roller 142 when being rolled up.

[0051] In the present application, the main body 110 is installed with a water storage member for storing condensed water. The water storage member can spray water onto the filter element 140 to wet the filter element 140. The wet filter screen 143 can greatly improve the filtering efficiency of the fresh air, and the dust entrained in the fresh air will adhere to the wet filter screen 143.

[0052] like Figure 1For example, the water delivery pipe 300 can be connected to a water pump after being led out of the unit case 100. The water pump is used to pump the condensed water collected by the water receiving box out of the unit case 100. The water outlet of the water pump is connected to the water inlet of the water storage component through a water pipe, thereby delivering the condensed water to the water storage component. The delivery pipe can be installed with a water treatment device 400, and the water treatment device 400 disinfects the condensed water to ensure that the condensed water is clean. In the embodiment of the present application, the water pump and the water treatment device 400 are both arranged outside the unit case 100, which is convenient for the installation and replacement of the water pump and the water treatment device 400.

[0053] In a specific example, a plurality of leakage holes 111 connected to the air duct are provided on the top of the main body 110, the top of the main body 110 is a hollow structure, and the water outlet of the water storage component is located at the top of the main body 110. In the embodiment of the present application, the water storage component can be installed on the top of the main body 110, or it can be installed in the air duct. When the water storage component is installed in the air duct, the water storage component drains condensed water to the top of the main body 110 through a water pipe, and the condensed water falls from the leakage hole 111 to the blade 121, and then flows downward under gravity, in the process of wetting the filter screen 143.

[0054] In the example of the present application, multiple blades 121 are arranged vertically. During the dripping process of water droplets, they are deflected by the airflow, so that the water droplets flowing from top to bottom can drip onto the filter 143, and when the water droplets flow downward along the blades 121, they will also flow to the first roller 141 of the filter element 140.

[0055] The main body 110 may be provided with a storage groove below the blade group 120, and the storage groove is used to collect water dripping from the blade group 120. The water storage component is equipped with a water level sensor, and the water outlet of the water storage component is equipped with a solenoid valve, which is electrically connected to the water level sensor. The water level sensor may be equipped with a main control board. The water level sensor monitors the water level in the water storage component and sends the water level information to the main control board. It can be understood that when the water level reaches a first preset water level, the main control board controls the solenoid valve to open, and when the water level reaches a second preset water level, the main control board controls the solenoid valve to close. The first preset water level is greater than the second preset water level to prevent excessive condensation water from overflowing the water storage component.

[0056] refer to Figure 4-5 As shown, two blade groups 120 are arranged at intervals in the extension direction of the air duct, so that the wind control device 200 forms a double-layer filtering structure to improve the air filtering effect. During the actual installation process, technical personnel in this field can install multiple blade groups as needed to further improve the filtering effect.

[0057] In summary, the present application provides a wind control device 200 and an air conditioning unit. The wind control device 200 is installed at the air inlet of the air conditioning unit. The wind control device 200 includes a main body 110, a blade group 120 and a driving member. A plurality of blades 121 are rotatably installed at the air duct of the main body 110. The plurality of blades 121 can be rotated to form an overlapping state in sequence, thereby closing the air duct. The plurality of blades 121 can also be rotated to open, and the gap between two adjacent blades 121 forms an air outlet. The present application sets a filter element 140 between two adjacent blades 121. When the blade 121 is rotated and opened, the filter element 140 is driven to unfold, and the filter element 140 can filter the air inlet. When the blade 121 rotates and closes, it drives the filter element 140 to close, so that the wind control device 200 closes the air duct. The air volume adjustment and air filtration are combined into one, and the original filter can be eliminated to reduce the size of the unit, make full use of the installation space of the unit, and reduce the installation process of the unit. At the same time, the filter element 140 can prevent mosquitoes from entering the air duct when the air duct is open, and prevent bacteria from breeding in the air duct. The wind control device 200 is installed with a water storage part, and the condensed water in the air-conditioning unit is collected into the water storage part through a pipeline, so that the condensed water wets the filter element 140. The moist filter screen 143 can greatly improve the filtering efficiency of the fresh air, and the dust entrained in the fresh air will adhere to the moist filter screen 143.
