Description

Technical Field

[0001] The invention relates to the technical field of air conditioning, and in particular to a vortex ring generating device, an air conditioning indoor unit and an air conditioner. Background Art

[0002] The existing air conditioner blows out the airflow after heat exchange through the conventional air outlet of the air conditioner. The air outlet mode is conventional, and the airflow out of the conventional air outlet is fixed and unchanged. Its radiation range is short and narrow, and it cannot achieve large-scale and long-distance air supply, which reduces the user experience.

[0003] By setting up a vortex ring generating device, long-distance air supply can be achieved. The vortex ring air supply part of the vortex ring generating device can be a piston structure, but the piston structure needs to achieve a good seal with the cavity wall, so that the driving force to push the piston to move is larger, and the reciprocating movement of the piston is easy to affect the sealing, thereby making the effect of compressing the volume in the cavity not good. The vortex ring air supply part can also be a structure of a whole film plus a push rod, that is, the film is stretched or contracted by the push rod to squeeze the air in the cavity to form a vortex ring and blow it out. However, this structure has extremely high requirements on the elasticity of the film material, and makes the damage rate of the film material high, thereby increasing the cost. At the same time, because the push rod pushes the film to deform, the force area and the action area of ​​the film are small, thereby making the effect of compressing the volume in the cavity not good, affecting the formation of the vortex ring and the blowing speed of the vortex ring airflow.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the meaning of "and / or" appearing in the full text is to include three parallel solutions. Taking "A and / or B" as an example, it includes solution A, or solution B, or a solution that satisfies both A and B.

[0045] The present invention provides a vortex ring generating device, which can be used alone or in combination with an air conditioner, a purifier and the like.

[0046] In the embodiment of the present invention, Figures 1 to 5As shown, the vortex ring generating device 100 includes a housing 1 and a vortex ring generating part 2. The housing 1 includes a wind tube 11 and a current collecting member 12. The wind tube 11 has a ventilation port 111 and an air outlet 112. The current collecting member 12 is installed at the air outlet 112. The current collecting member 12 is formed with an air supply port 121 connected to the wind tube 11. The air flow area of ​​the air supply port 121 is smaller than the air flow area of ​​the air outlet 112. The vortex ring generating part 2 includes a push plate assembly 21 and a driving device 22. The push plate assembly 21 is arranged in the housing 1. The push plate assembly 21 includes a flexible member 211 and a push plate 212 connected to the flexible member 211. The flexible member 211 is connected to the peripheral wall surface 115 of the housing 1. The push plate 212 is arranged toward the air supply port 121. The driving device 22 drives the push plate 212 to move back and forth between the ventilation port 111 and the air supply port 121, so as to periodically drive the air flow to be blown out from the air supply port 121.

[0047] In this embodiment, the inner cavity of the shell 1 forms a vortex ring air duct, and the shape of the shell 1 can be a straight cylinder or a bent cylinder, and its cross-section can be rectangular, circular, elliptical, polygonal, or irregular, etc., which are not specifically limited here. The overall shape of the vortex ring air duct and its cross-sectional shape can be selected according to the use requirements, which are not specifically limited here. The flexible member 211 is connected to the peripheral wall surface 115 of the shell 1, and the shape of the flexible member 211 is roughly compatible with the shape of the inner cavity of the shell 1. The shape of the push plate 212 can be circular, elliptical, rectangular, irregular, etc., which are not specifically limited here.

[0048] The shape of the ventilation port 111 may be circular, rectangular, elliptical, polygonal, etc., or may be a plurality of holes or micropores, which are not specifically limited here. The shapes of the air outlet 112 and the air supply port 121 may be circular, rectangular, elliptical, polygonal, etc. The air cylinder 11 is roughly cylindrical. In one embodiment, the collector 12 is a collector hood, which is gradually tapered from the air outlet 112 to the air supply port 121. The cross-sectional shape of the collector hood may be circular, elliptical, rectangular, etc. In order to reduce wind resistance, the collector hood is roughly cylindrical. By gradually tapering the collector hood from the air outlet 112 to the air supply port 121, the collector hood can collect the wind sent out from the air outlet 112, and make the generation and blowing of the vortex ring smoother.

[0049] In another embodiment, the current collecting member 12 is a current collecting plate, which is mounted on the air outlet 112, and an air supply port 121 is provided on the current collecting plate. The current collecting plate can be a plate that covers the air outlet 112, and by providing an air supply port 121 that is smaller than the air outlet 112 on the current collecting plate, when the airflow is blown out from the air outlet 112 to the air supply port 121, due to the partial blocking effect of the current collecting plate, the airflow blown out of the air supply port 121 can be in the shape of a vortex ring. The current collecting plate has a simple structure and is easy to manufacture and process. In other embodiments, the current collecting member 12 can also be formed by enclosing several plates, and by providing an air supply port 121 on one of the plates, the formation of a vortex ring can also be achieved.

[0050] The current collecting part 12 and the wind tube 11 can be integrally formed or separately formed. It can be understood that when the current collecting part 12 and the wind tube 11 are separately formed, the current collecting part 12 and the wind tube 11 are sealed and connected. When the current collecting cover and the wind tube 11 are integrally formed, a virtual dividing line is divided by the junction of the wind tube 11 and the current collecting part 12. One side of the dividing line is the wind tube 11, and the other side is the current collecting part 12, and the air outlet 112 of the wind tube 11 is formed at the dividing line. Undoubtedly, the air flow area of ​​the air outlet 112 is larger than the air flow area of ​​the air supply port 121 of the current collecting part 12. The extension direction of the outer wall surface of the current collecting part 12 and the wind tube 11 can be consistent, that is, the length extension line of the outer wall surface of the two is a straight line. At this time, the vortex ring air supply part is a complete shape without a transfer line. The extension directions of the outer wall of the current collecting member 12 and the wind tube 11 may be inconsistent, that is, the length extension lines of the outer walls of the two are arranged at an angle. In this case, a transfer line will be formed at the connection between the current collecting member 12 and the wind tube 11.

[0051] By making the wind flow area of ​​the air supply port 121 smaller than the wind flow area of ​​the air outlet 112, part of the airflow flowing from the air outlet 112 to the air supply port 121 will flow along the inner wall surface of the collector 12, and then flow out from the periphery of the air supply port 121, while the other part of the airflow will flow out from the middle of the air supply port 121. The part of the airflow flowing out from the edge of the air supply port 121 is defined as the edge airflow, and the airflow flowing out from the middle of the air supply port 121 is positioned as the middle airflow. Then, the edge airflow is subject to the resistance of the inner wall surface of the collector 12. Compared with the middle airflow, the flow velocity is lower. This difference in flow velocity will cause a vortex ring airflow to be generated when the airflow flows out of the air supply port 121. Under the same air volume, the vortex ring air supply method can achieve directional, fixed-point and long-distance air supply. Moreover, the vortex ring exchanges heat with the surrounding air during the transmission process, and the temperature difference between the vortex ring and the surrounding air is not large, which ensures that the vortex ring will not produce obvious feeling of overcooling or overheating when blowing on the human body, thereby improving comfort.

[0052] The flexible member 211 refers to a structure that can be easily deformed but not easily destroyed, and has the characteristics of being quickly foldable and retractable. The material of the flexible member 211 can be a cloth material such as nylon, cotton, fiber, a plastic material such as polyethylene, polypropylene, polyester, a rubber material, etc. It is only necessary to make the flexible member 211 flexible, foldable and retractable, and the material of the flexible member 211 is not specifically limited here. The push plate 212 is a plate-like structure. The edge of the flexible member 211 can be connected to the inner wall surface of the shell 1, or the part of the flexible member 211 close to the edge can be connected to the inner wall surface of the shell 1. The flexible member 211 can be connected to the shell 1 by screws, bonding, crimping, etc., and the specific connection method is not limited here. The flexible member 211 can be connected in the wind tube 11, in the current collecting member 12, or at the connection between the wind tube 11 and the current collecting member 12. In order to make the moving path of the push plate 212 longer and the compression effect better, the flexible member 211 is selected to be connected to the position near the ventilation port 111 in the wind tube 11. The push plate 212 and the flexible member 211 may be fixed by bonding, crimping, screw connection or the like.

[0053] It can be understood that the push plate assembly 21 divides the inner cavity of the shell 1 into two along the axial direction of the shell 1. The flexible member 211 can divide the inner cavity of the shell 1 into two as a whole, and the push plate 212 is connected to one side of the flexible member 211. Alternatively, the flexible member 211 can only seal the peripheral position, and the push plate 212 can seal the middle position. Then, the flexible member 211 and the push plate 212 together divide the inner cavity of the shell 1 into two along the axial direction. Due to the foldable and stretchable structural characteristics of the flexible member 211, the push plate 212 can move back and forth within a certain range without destroying the flexible member 211. In addition, during the movement of the push plate 212, the flexible member 211 and the inner cavity of the shell 1, as well as the flexible member 211 and the push plate 212, are always sealed. The two chambers separated by the push plate assembly 21 will not be connected to each other, and the push plate 212 has a better effect of squeezing the gas in one side of the cavity during the movement. The push plate assembly 21 has good sealing performance, high reliability, and simple structure.

[0054] The structure of the driving device 22 can be of many kinds. In one embodiment, the driving device 22 includes an electromagnetic driving member 221 and a push rod, one end of the push rod is connected to the push plate 212, and the other end is connected to the electromagnetic driving member 221. The push rod is driven to reciprocate by turning on and off the power of the electromagnetic driving member 221 to drive the push plate 212 to reciprocate between the air supply port 121 and the ventilation port 111. In another embodiment, the driving device 22 includes a driving motor, a mutually meshing vortex ring and a worm, one end of the worm is connected to the push plate 212, and the other end is connected to the turbine, and the turbine is fixedly installed with the driving shaft of the driving motor. The driving motor drives the turbine to rotate, driving the worm to reciprocate, and then driving the push plate 212 to reciprocate between the air supply port 121 and the ventilation port 111. In another embodiment, the driving device 22 includes a driving motor, an eccentric wheel and a connecting rod, the eccentric wheel is arranged on the driving motor, one end of the connecting rod is connected to the rotating shaft of the eccentric wheel, and the other end is connected to the push plate 212. In this way, the connecting rod can drive the push plate 212 to reciprocate.

[0055] When the vortex ring airflow needs to be pushed out, the driving device 22 drives the push plate 212 to move toward the ventilation port 111 to discharge the gas in the housing 1 from the ventilation port 111, and then the driving device 22 drives the push plate 212 to move quickly toward the air supply port 121, and the push plate 212 pushes the airflow to be blown out quickly from the air supply port 121. By making the air flow area of ​​the air supply port 121 smaller than the air flow area of ​​the air outlet 112, the vortex ring airflow can be blown out from the air supply port 121. This cycle is repeated, and the vortex ring airflow can be blown out from the air supply port 121 periodically.

[0056] The vortex ring generating device 100 of the present invention makes the push plate assembly 21 consist of a flexible member 211 and a push plate 212. The flexible member 211 is connected to the peripheral wall surface 115 of the shell 1, and the push plate 212 is connected to the flexible member 211 and is arranged toward the air supply port 121. The driving device 22 drives the push plate 212 to move back and forth between the ventilation port 111 and the air supply port 121. The structure of the flexible member 211 plus the push plate 212 is simple. On the one hand, the flexible member 211 is used to extend and fold, and the movement of the push plate 212 is not affected while ensuring that the push plate assembly 21 is always sealed with the inner wall surface of the shell 1. The push plate assembly 21 can better squeeze the volume in the shell 1, with high reliability, and the movement of the push plate 212 is smoother, the required driving force is smaller, and the material performance requirements of the flexible member 211 are low, which effectively reduces the cost. On the other hand, the push plate 212 is used to push the flexible member 211 to extend and fold, so that the force-bearing area is large and the pushing is smoother. In addition, the effective area of ​​the push plate 212 is large at the same pushing distance, so that the vortex ring can be blown farther and the radiation range is wider.

[0057] In one embodiment, the flexible member 211 is configured to be stretchable or retractable. The flexible member 211 has the properties of being foldable and retractable, and also has the properties of being stretchable or retractable. In this way, the flexible member 211 is deformable and has a certain elasticity, so that the push plate 212 connected to the flexible member 211 can move a longer distance, and the push plate assembly 21 has a better effect of pushing the airflow, and the vortex ring can deliver air farther and has a wider radiation range. At this time, the flexible member 211 can be made of materials such as rubber and silicone.

[0058] On the basis of the above-mentioned embodiment in which the flexible member 211 is stretched or retracted, further, when the flexible member 211 is in a natural state, the flexible member 211 is arranged in a flat sheet shape, a mounting hole is provided in the middle of the flexible member 211, and the push plate 212 is connected to the mounting hole accordingly. In the natural state, the flexible member 211 is arranged in a flat sheet shape, that is, the flexible member 211 is arranged in a sheet or flat shape in an unstretched state. The shape of the mounting hole provided in the middle of the flexible member 211 can be the same as that of the push plate 212, or it can be different. In order to ensure the sealing, the push plate 212 should completely cover the mounting hole. By utilizing the elastically deformable performance of the flexible member 211, the push plate 212 can be movable while ensuring the sealing to squeeze the gas in the shell 1, which can effectively reduce noise, and the structure is simpler and easier to implement. The flexible member 211 which is arranged in a flat sheet shape has a hole in the middle, which can reduce the volume of the flexible member 211 and reduce the cost. On the other hand, compared with setting the push plate 212 in the middle of the entire flexible member 211, the movement of the push plate 212 is smoother.

[0059] In one embodiment, please refer to Figure 2 , Figure 3 , Figure 5 and Figure 6 When the flexible member 211 is in a natural state, the flexible member 211 is cylindrically arranged and has a first end 10 and a second end 20 opposite to each other. The push plate 212 is connected to the first end 10, and the second end 20 is connected to the shell 1 and is openly arranged. The flexible member 211 is gradually expanded from the first end 10 to the second end 20.

[0060] In this embodiment, when the flexible member 211 is in a natural state, it means that when the flexible member 211 has only foldable and stretchable properties, it is in a natural stretch state, and when the flexible member 211 also has stretchable and shrinkable properties, it is in a natural stretch state without deformation. The first end 10 of the flexible member 211 can be set in an open state or a sealed state. In order to simplify the structure and make the movement of the push plate 212 smoother, the first end 10 is set in an open state, and the push plate 212 should cover the opening of the first end 10. By making the flexible member 211 cylindrical, the moving distance of the push plate 212 is at least the length of the cylindrical flexible member 211. By folding and stretching the cylindrical flexible member 211 in the axial direction, the movement of the push plate 212 can be achieved. The structure is simple, the material performance requirements of the flexible member 211 are low, the cost is reduced, and the reliability and sealing are high. By making the flexible member 211 gradually expand from the first end 10 to the second end 20, the push plate 212 can pass through the opening of the second end 20 during its movement, that is, the push plate 212 can turn around the second end 20. In this way, the moving distance of the push plate 212 is greatly increased, so that the push plate 212 has a better effect of squeezing and pushing the airflow, and the vortex ring sends air over a longer distance.

[0061] In other embodiments, the flexible member 211 can also be roughly arranged in a straight cylindrical shape, the first end 10 of the flexible member 211 is connected to the push plate 212, the push plate 212 and the inner wall surface of the shell 1 are arranged with a gap, and the second end 20 of the flexible member 211 is connected to the shell 1 and is arranged in an open shape.

[0062] In combination with the above-mentioned embodiment in which the flexible member 211 is arranged in a cylindrical shape, further, the vortex ring generating part 2 also includes a first mounting ring 23 installed on the first end 10 and a second mounting ring 24 installed on the second end 20, the second mounting ring 24 is connected to the inner wall surface of the shell 1, and the first mounting ring 23 is connected to the push plate 212.

[0063] In this embodiment, the first mounting ring 23 and the second mounting ring 24 can be made of hard materials such as hard plastic and hard rubber. The first mounting ring 23 and the flexible member 211, as well as the second mounting ring 24 and the flexible member 211 can be connected by means of screws, inlaying, crimping, bonding, etc. It can be understood that due to the flexibility of the flexible member 211, it is difficult to operate and not easy to achieve when connecting the flexible member 211 with other structures. Therefore, by first connecting the first end 10 and the second end 20 of the flexible member 211 with the first mounting ring 23 and the second mounting ring 24, when it is necessary to connect and install the flexible member 211, it is only necessary to connect other structures with the first mounting ring 23 and the second mounting ring 24. This makes the installation of the flexible member 211 and other structures simpler and faster.

[0064] Specifically, Figure 3As shown, the peripheral wall surface 115 of the wind tube 11 is provided with an installation step 113, and the second installation ring 24 is installed on the installation step 113. The installation step 113 on the inner wall surface of the wind tube 11 can be arranged around the circumference of the tube wall surface. The second installation ring 24 is connected to the installation step 113, which, on the one hand, plays a role in limiting and positioning the installation of the flexible member 211, and on the other hand, makes the connection between the second installation ring 24 and the wind tube 11 more convenient and quick. The second installation ring 24 and the installation step 113 can be connected by screws, bonding, etc.

[0065] In one embodiment, if Figure 4 As shown, the cross-sectional area of ​​the push plate 212 is greater than or equal to the wind passing area of ​​the air outlet 121. It is understandable that the push plate 212 is arranged toward the air outlet 121, and the push plate 212 sends the airflow out of the air outlet 121 when squeezing and pushing the airflow. Therefore, the cross-sectional area of ​​the push plate 212 will greatly affect the delivery speed and disturbance degree of the airflow. By making the cross-sectional area of ​​the push plate 212 larger than the wind passing area of ​​the air outlet 121, it is possible to ensure that the push plate 212 has a sufficiently large effective area, thereby increasing the airflow speed and airflow volume blown out of the air outlet 121, so that the vortex ring blows farther and has a wider radiation range.

[0066] In one embodiment, the driving device 22 includes a driving member 221, a transmission member 222 and a reset member 223. The transmission member 222 is connected to the push plate 212. The driving member 221 drives the transmission member 222 to drive the push plate 212 to move toward the ventilation port 111 or the air supply port 121. One end of the reset member 223 is connected to the shell 1, and the other end is connected to the push plate 212 to drive the push plate 212 to reset and move in a direction opposite to the transmission direction of the transmission member 222.

[0067] In this embodiment, the transmission member 222 can be a structure such as a gear 30 and a rack 40, a turbine and a worm that mesh with each other. The rack 40 or the worm is connected to the push plate 212. The gear 30 or the turbine is driven by the driving member 221 to drive the rack 40 or the worm to move, thereby driving the push plate 212 to move toward one side of the ventilation port 111 or the air supply port 121. The push plate 212 is reset and moved in the direction opposite to the transmission direction of the transmission member 222 by the action of the reset member 223. The reset member 223 is cleverly used so that the driving member 221 only drives the push plate 212 to move in one direction, thereby reducing the requirements for the driving member 221 and reducing the cost. The reset effect of the reset member 223 is good and can meet the needs of sending out the vortex ring.

[0068] For details, please refer to Figures 2 to 4The driving member 221 is a motor, and the transmission member 222 includes a gear 30 and a rack 40 that mesh with each other. The rack 40 is connected to the push plate 212, and the driving shaft of the motor is fixedly connected to the gear 30 to drive the rack 40 to move and drive the push plate 212 to move. The rack 40 can be fixedly connected to the push plate 212 by connecting parts such as screws. Driven by a motor, it has a small size, occupies a small space, and has sufficient driving force. In order not to affect the generation of vortex ring airflow, the motor and the gear 30 can be placed outside the housing 1, so that the rack 40 passes through the bottom wall 114 of the wind tube 11 and meshes with the gear 30. The motor drives the gear 30 to rotate to drive the rack 40 to move, and then drives the push plate 212 to move. The structure is simple, easy to implement, and easy to control.

[0069] In conjunction with the above-mentioned embodiment in which the transmission member 222 includes a gear 30 and a rack 40 meshing with each other, please refer to Figure 7 Furthermore, the gear 30 is an incomplete gear 30. When the rack 40 is engaged with the toothed portion 30a of the incomplete gear 30, the push plate 212 is driven to move toward the ventilation port 111. When the rack 40 corresponds to the toothless portion 30b of the incomplete gear 30, the push plate 212 is moved toward the air supply port 121 under the action of the reset member 223.

[0070] In this embodiment, the gear 30 is an incomplete gear 30, and the gear 30 has a toothed portion 30a and a toothless portion 30b. When the rack 40 is meshed with the toothed portion 30a of the incomplete gear 30, the motor drives the gear 30 to rotate to drive the rack 40 to move, and then drive the push plate 212 to move toward the side of the ventilation port 111, and at this time, the reset member 223 is compressed. When the gear 30 rotates to the toothless portion 30b corresponding to the rack 40, the gear 30 and the rack 40 are separated from each other, and under the reset force of the reset member 223, the push plate 212 is quickly pushed to move toward the side of the air supply port 121, so that the airflow passes through the air supply port 121 quickly, thereby forming a vortex ring airflow. By designing the ratio of the toothed portion 30a to the toothless portion 30b, that is, designing the number of gear teeth on the gear 30, the reciprocating distance of the push plate 212 can be controlled, and then the speed of the blown vortex ring airflow can be easily controlled, and directional, fixed-point and long-distance air supply can be achieved. When the gear 30 and the rack 40 are disengaged from each other, the reset member 223 pushes the push plate 212 toward the air outlet 121. Compared with the motor driving the push plate 212 to move toward the air outlet 121, the pushing speed is faster and the motor speed requirement is lower, thereby making the overall design more reasonable and reducing the overall cost.

[0071] In one embodiment, if Figures 2 to 5As shown, the reset member 223 is a spring, and the driving device 22 further includes a guide rod 224, which is connected to the housing 1. The push plate 212 is provided with a guide hole for the guide rod 224 to pass through, and the spring is sleeved on the periphery of the guide rod 224. It can be understood that the push plate 212 can move along the axial direction of the guide rod 224. The reset member 223 is a spring, which has a simple structure, sufficient reset driving force, and low cost. By sleeve-arranging the spring on the guide rod 224, the guide rod 224 plays a supporting and guiding role for the spring, and then plays a guiding role for the movement of the push plate 212.

[0072] On the basis of the above embodiment, further, there are multiple guide rods 224, and the multiple guide rods 224 are arranged at circumferential intervals along the push plate 212, the vortex ring generating part 2 also includes a clamping piece 25 connected to the push plate 212, the flexible piece 211 is clamped between the push plate 212 and the clamping piece 25, the guide rod 224 is passed through the clamping piece 25, and the spring is connected to the clamping piece 25.

[0073] In this embodiment, a plurality of guide rods 224 can be evenly spaced along the circumference of the push plate 212. There are also a plurality of springs corresponding to the number of guide rods 224. A plurality of guide rods 224 and a plurality of springs are provided to achieve better guiding and resetting effects. The push plate 212 is connected by a clamping member 25, and the flexible member 211 is clamped therebetween. In this way, not only the connection between the flexible member 211 and the push plate 212 is more stable, but also, when moving, the clamping member 25 drives the push plate 212 to move along the axial direction of the guide rod 224, and can compress the spring, thereby increasing the contact area with the guide rod 224 and making the guiding more stable. The clamping member 25 can be a pressure ring or a pressure plate. In order to reduce the weight of the entire vortex ring generating part 2, the clamping member 25 is designed in the form of a pressure ring.

[0074] In one embodiment, please refer to Figure 2 and Figure 4 , the vortex ring generating device 100 also includes a fixed bracket 3, the fixed bracket 3 is crimped on the flexible member 211 and connected to the shell 1, one end of the guide rod 224 is connected to the fixed bracket 3, and the other end is connected to the shell 1. The fixed bracket 3 can be an annular structure. The fixed bracket 3 and the shell 1 can be connected by screws, clamping, glue bonding, etc. By setting the fixed bracket 3 to crimp the flexible member 211 and connect it to the shell 1, the connection between the flexible member 211 and the shell 1 is more stable. And the fixed bracket 3 can play the role of connecting and fixing the guide rod 224, so that the overall structure is more stable.

[0075] In one embodiment, please refer to Figure 2 and Figure 3The air duct 11 includes a bottom wall surface 114 and a peripheral wall surface 115. The air duct 11 also has a ventilation port 111, which is opened on the bottom wall surface 114 and / or the peripheral wall surface 115. The ventilation port 111 can be a plurality of holes arranged at intervals, or a circular hole, etc. In order to achieve a better ventilation effect, a plurality of ventilation ports 111 are opened at the connection between the bottom wall surface 114 and the peripheral wall surface 115 of the air duct 11.

[0077] In one embodiment, the housing 200 of the air conditioner indoor unit has a main air inlet, a main air outlet, and a heat exchange air duct connecting the main air inlet and the main air outlet, the vortex ring generating device 100 is installed in the heat exchange air duct, and the ventilation port 111 is connected to the heat exchange air duct.
