Description

Technical Field

[0001] This invention relates to the field of fresh air conditioning technology, specifically to an intelligent control humidification and ventilation integrated machine. Background Technology

[0002] With the increasing demands for airtightness and energy efficiency in modern buildings, indoor air quality has become a major concern. Traditional ventilation relies primarily on opening windows, but in urban environments with poor air quality, this method not only leads to direct exchange of indoor and outdoor pollutants but can also cause secondary pollution problems such as noise and dust. Furthermore, modern buildings have increasingly stringent energy-saving requirements, and traditional window ventilation can cause drastic fluctuations in indoor temperature, increasing energy consumption for air conditioning and heating systems.

[0003] To address these issues, fresh air systems were developed. A fresh air system is a ventilation device that facilitates the exchange of indoor and outdoor air. Its core function is to mechanically introduce fresh outdoor air into the room while simultaneously expelling stale indoor air, thus maintaining fresh and healthy indoor air. Fresh air systems can reduce the loss of heat and cold indoors through heat exchange technology, achieving ventilation while simultaneously maintaining indoor temperature. Furthermore, to ensure indoor humidity, a humidifier is often integrated into the fresh air system. The humidifier evaporates water vapor through electric heating and brings it into the room with the fresh air. However, because the heating element in the humidifier requires time to change temperature, its response speed is slow, making it difficult to quickly adjust the humidity according to the user's needs. Summary of the Invention

[0007] Preferably, the outer diameter of the upper plate is adapted to the inner diameter of the air outlet hood; the upper end of the air outlet hood expands outward and is fixedly connected to an annular collection part; the collection part is inclined downward and has a return hole; the edge of the upper plate extends beyond the lower plate and is provided with filter holes extending vertically; the center of the air outlet hood is fixedly connected to a central rod; the outer wall of the central rod is provided with external threads; the center of the upper plate is provided with an internal threaded hole; the internal threaded hole is connected to the external thread on the outer wall of the central rod.

[0008] Preferably, the upper end of the collecting part is turned inward and its inner diameter is adapted to the inner diameter of the air outlet hood; a mesh cover is provided on the inner side of the collecting part; a rectangular strip is fixedly connected to the lower center of the mesh cover; a rectangular groove is provided on the upper end of the central rod; and the rectangular strip is inserted into the rectangular groove.

[0009] Preferably, the upper plate has an opening and closing groove extending vertically through the lower plate, extending beyond the upper plate's edge; there are multiple opening and closing grooves; these grooves are evenly distributed around the center of the upper plate; an opening and closing plate is hinged within each groove; a stop block is fixedly connected to the lower part of the inner wall of each groove; the filter hole is disposed on the opening and closing plate; the opening and closing plate opens when the upper plate moves downward and closes when the upper plate moves upward.

[0010] Preferably, the upward rotation direction of the upper plate is the same as the direction from the movable end to the hinge end of the opening and closing plate; the downward rotation direction of the upper plate is the same as the direction from the hinge end to the movable end of the opening and closing plate.

[0011] Preferably, the height of the external thread on the outer wall of the center rod does not exceed that of the air outlet hood; and when the upper surface of the upper plate is not lower than that of the air outlet hood, the internal thread hole at the center of the upper plate is disengaged from the external thread on the outer wall of the center rod.

[0012] Preferably, the rectangular strip and the rectangular groove are slidably sealed together; the inner and outer walls of the square tube are provided with a vent hole at the lower position; the bottom of the rectangular groove and the wall of the square groove are provided with an L-shaped hole; when the upper surface of the upper plate is flush with the upper end of the air outlet hood, the vent hole and the L-shaped hole are aligned.

[0013] Preferably, the upper plate has an upward-bulging upper surface and an arc-shaped cross-section; the lower plate has a downward-bulging lower surface and an arc-shaped cross-section.

[0014] The beneficial effects of this invention are as follows:

[0015] 1. This invention controls the vertical position of the upper end of the square tube within the air outlet hood, thereby controlling the contact path length between the gas flowing out of the upper end of the square tube and the water within the air outlet hood, and thus indirectly and quickly regulates the indoor air humidity of the building.

[0016] 2. This invention can clean the water impurities in the air outlet hood every time the machine is stopped, ensuring water cleanliness and improving the cleanliness of the indoor environment and humidification effect.

[0017] 3. During the downward movement of the upper plate, the water between the lower surface of the upper plate and the bottom wall of the air outlet hood will be squeezed. The water will pass through the opening and closing groove from bottom to top and push open the opening and closing plate in the opening and closing groove. Compared with the original water passing through the filter holes on the opening and closing plate, on the one hand, the resistance of the upper plate moving downward is reduced, and on the other hand, the water flow and splashing in the air outlet hood are reduced, making the water in the air outlet hood more stable and avoiding overflow.

[0018] 4. During the upward movement of the upper plate, the upper plate rotates in the same direction as the hinge end of the opening and closing plate. This makes it easier and faster for the opening and closing plate to close in the corresponding opening and closing groove as the upper plate rotates, ensuring timely closing of the opening and closing plate during the upward movement of the upper plate and minimizing the risk of impurities directly passing through the opening and closing groove and entering the area below the upper plate. During the downward movement of the upper plate, the upper plate also rotates in the same direction as the hinge end of the opening and closing plate. This allows the opening and closing plate to be opened at a certain angle, and with the rotation of the upper plate, the opening and closing plate further opens under the push of the water flow, increasing the opening angle of the opening and closing plate in the opening and closing groove. This makes it easier for water below the upper plate to pass through the opening and closing groove and enter the area above the upper plate, facilitating water flow. Attached Figure Description

Detailed Implementation

[0031] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0032] like Figures 1 to 10As shown, the present invention includes the following embodiments:

[0033] Example 1: A smart control humidifier and ventilation integrated machine includes a housing 1 and a heat exchange core 11 at the center of the housing 1; the four corners inside the housing 1 are separated by partition plates 12 and the heat exchange core 11; the four corners of the housing 1 are, in clockwise order, a first air inlet chamber 13, a second air outlet chamber 14, a first air outlet chamber 15, and a second air inlet chamber 16; the first air inlet chamber 13, the second air outlet chamber 14, and the second air inlet chamber 16 are connected to the outside through connectors 17 on the side wall of the housing 1; the connectors 17 in the first air inlet chamber 13 and the second air inlet chamber 16 are connected to a filter screen 18 and... Fan 19; an air outlet cover 2 is fixedly connected to the upper surface of the housing 1; a square groove 21 communicating with the inner side of the air outlet cover 2 is provided through the first air outlet cavity 15 facing upward; a square tube 3 is slidably and sealed inside the square groove 21; a pull rope 31 and a first spring 32 are connected to the upper end of the inner side of the square tube 3; a motor 33 and a U-shaped spring seat 34 are fixedly connected to the lower inner wall of the first air outlet cavity 15; the lower end of the pull rope 31 is connected to the output shaft of the motor 33; the lower end of the first spring 32 is connected to the spring seat 34; a water inlet pipe 22 is provided to the outer side of the inner bottom wall of the air outlet cover 2.

[0034] During operation, after the fresh air conditioning equipment is put into operation, the two fans 19 are started. The fan 19 in the first air inlet chamber 13 draws outside air into the first air inlet chamber 13 along the corresponding connector 17 and filter 18. The air in the first air inlet chamber 13 passes through the heat exchange core 11 and enters the first air outlet chamber 15. The fan 19 in the second air inlet chamber 16 draws indoor air into the second air inlet chamber 16 along the corresponding connector 17 and filter 18. The air in the second air inlet chamber 16 passes through the heat exchange core 11 and enters the second air outlet chamber 14. The air in the second air outlet chamber 14 is discharged to the outside along the corresponding connector 17. The indoor air and the outdoor air undergo heat exchange during the process of passing through the heat exchange core 11. Heat exchange is used to reduce the loss of indoor temperature and achieve the purpose of heat preservation. The gas in the first air outlet chamber 15 flows out from bottom to top along the inner side of the square tube 3. A water level sensor is installed in the air outlet hood 2, which is filled with water. The water is injected into the inner side of the air outlet hood 2 through the water inlet pipe 22. As gas continuously flows out from the inner side of the square tube 3, the gas enters the inner side of the air outlet hood 2 and comes into contact with the water. During the process of the gas flowing from bottom to top in the water, it comes into contact with water molecules. In this way, the gas carries water molecules and flows out of the air outlet hood 2, increasing the water content of the gas flowing out of the air outlet hood 2, thereby ensuring the humidity of the air entering the room. When it is necessary to increase the indoor air humidity, the motor 33 is controlled to rotate. The motor 33 drives the output shaft to rotate and pull the rope 3. The lower end of the pull rope 31 is wound around the upper end of the square tube 3. The upper end of the pull rope 31 is connected to the upper end of the square tube 3. Therefore, after the lower end of the pull rope 31 is wound, the square tube 3 will slide and move downwards along the square groove 21. During this downward movement, the square tube 3 will overcome the elastic force of the first spring 32 and move downwards. The position of the upper end of the square tube 3 within the air outlet hood 2 moves downwards along with the square tube 3, increasing the depth of the gas discharged from the upper end of the square tube 3 within the air outlet hood 2. This prolongs the contact path between the gas and the water within the air outlet hood 2, increasing the contact time between the gas and the water within the air outlet hood 2, allowing the gas to carry more water molecules, increasing the gas's water content, and further increasing the indoor humidity. This is useful when it is necessary to reduce indoor air humidity. When the motor 33 reverses, the output shaft will be released, and the lower end of the pull rope 31 will be released. The first spring 32 will transmit the elastic force to the square tube 3, causing the upper end of the square tube 3 to move upward. This reduces the depth of the gas discharged from the upper end of the square tube 3 in the air outlet hood 2, thereby shortening the contact path between the gas and the water in the air outlet hood 2 and reducing the contact time between the gas and the water in the air outlet hood 2. This reduces the water content carried by the gas flowing out of the air outlet hood 2, further reducing the indoor humidity. When the fresh air conditioning equipment stops operating, after controlling the upper end of the square tube 3 to be higher than the liquid level inside the air outlet hood 2, the operation of the fan 19 can be stopped.

[0035] This invention controls the vertical position of the upper end of the square tube 3 within the air outlet hood 2, thereby controlling the contact path length between the gas flowing out of the upper end of the square tube 3 and the water within the air outlet hood 2, and thus indirectly and quickly regulates the indoor air humidity of the building.

[0036] Example 2: The upper end of the square tube 3 is fixedly connected to an annular lower plate 4; the outer diameter of the lower plate 4 is smaller than the inner diameter of the air outlet hood 2; the center of the lower plate 4 is rotatably and sealingly connected to the center of the lower surface of the upper plate 5; the upper plate 5 is located above the lower plate 4; an annular lower cavity 41 is provided inside the lower plate 4; the lower cavity 41 is connected to the interior of the square tube 3; the inner wall of the lower cavity 41 radially penetrates the center of the lower plate 4; an annular upper cavity 51 is provided inside the upper plate 5; the lower end of the upper cavity 51 is connected to the lower cavity 41 through a first air hole 52, and multiple second air holes 53 are evenly provided through the upper end of the upper cavity 51.

[0037] In this embodiment, the outer diameter of the upper plate 5 is adapted to the inner diameter of the air outlet hood 2; the upper end of the air outlet hood 2 is expanded outward and fixedly connected to the annular collection part 6; the collection part 6 is inclined downward and has a return hole 61 passing through it; the edge of the upper plate 5 is provided with a filter hole 71 extending vertically beyond the lower plate 4; the center of the air outlet hood 2 is fixedly connected to the center rod 8; the outer wall of the center rod 8 is provided with an external thread 81; the center of the upper plate 5 is provided with an internal thread hole 54; the internal thread hole 54 is threadedly connected to the external thread 81 on the outer wall of the center rod 8.

[0038] In this embodiment, the upper end of the collecting part 6 is turned inward and its inner diameter is adapted to the inner diameter of the air outlet cover 2; a mesh cover 62 is provided on the inner side of the collecting part 6; a rectangular strip 63 is fixedly connected to the lower center of the mesh cover 62; a rectangular groove 82 is provided on the upper end of the central rod 8; the rectangular strip 63 is inserted into the rectangular groove 82.

[0039] During operation, the gas inside the square tube 3 enters the lower chamber 41, and then flows through the first vent 52 into the upper chamber 51. The gas in the upper chamber 51 then exits through the second vent 53. A heating wire can be embedded in the lower plate 4 for auxiliary heating. The position of the heating wire on the lower plate 4 moves with the position of the upper plate 5, resulting in a higher and more active water temperature around the upper plate 5. Because there are multiple second vents 53, the gas flowing out from the upper end of the square tube 3 is dispersed, increasing the contact area with the water in the air outlet hood 2, thereby improving the humidification effect. Although the gas must pass through the filter screen 18 before entering the square tube 3, residual impurities... As airflow passes through the water inside the exhaust hood 2, it also causes water contamination. When the operator needs to adjust the vertical position of the upper plate 5 inside the exhaust hood 2, the upper plate 5 will move along with the lower plate 4 and the square tube 3. During the upward movement of the upper plate 5, the water flow above the upper plate 5 will enter below the upper plate 5 through the filter hole 71. The water inlet pipe 22 will only open when there is a lack of water in the exhaust hood 2; otherwise, it will be closed. During the downward movement of the upper plate 5, the water flow below the upper plate 5 will pass through the filter hole 71 and enter above the upper plate 5. Impurities are always intercepted above the upper plate 5. During each shutdown, the square tube 3 will move upward. During the process, the lower plate 4 will move upward, which in turn will cause the upper plate 5 to move upward. The upper plate 5 will move axially along the central rod 8 during this upward movement. Since the upper plate 5 has an internal threaded hole 54 at its center and the central rod 8 has an external thread 81 on its outer wall, the upper plate 5 will rotate during this upward movement. When the upper plate 5 is exposed above the water surface of the exhaust hood 2, the water above the upper plate 5 flows down through the filter holes 71 to the area below the upper plate 5. The upper plate 5 will collect impurities, and when the upper surface of the upper plate 5 is higher than the collection section 6, the impurities and residual water on the upper surface of the upper plate 5 will be thrown into the collection section 6 under centrifugal force. The collection section 6 is used to collect impurities, and excess water flows down through the return holes 61 to the exhaust hood. Inside the hood 2, impurities in the water can affect humidification and indoor air quality. Since the impurities in the water inside the hood 2 can be cleaned every time the machine is stopped, the water is kept clean, improving the cleanliness of the indoor environment and the humidification effect. After the impurities on the upper surface of the upper plate 5 are thrown out, they will move upward and contact the mesh cover 62. The upward movement of the upper plate 5 will block the upper port of the collection section 6, thereby blocking the water inside the hood 2 during the shutdown process and preventing the water inside the hood 2 from being contaminated. The staff can periodically lift the mesh cover 62. When the mesh cover 62 is lifted, it will drive the rectangular strip 63 to move in the rectangular groove 82. After removing the mesh cover 62, the impurities in the collection section 6 can be cleaned.

[0040] Example 3: An opening and closing groove 55 is provided vertically through the edge of the upper plate 5, extending beyond the edge of the lower plate 4; there are multiple opening and closing grooves 55; the multiple opening and closing grooves 55 are evenly distributed around the center of the upper plate 5; an opening and closing plate 7 is hinged inside the opening and closing groove 55; a stop block 56 is fixedly connected to the lower part of the inner wall of the opening and closing groove 55; the filter hole 71 is provided on the opening and closing plate 7; the opening and closing plate 7 opens when the upper plate 5 moves downward and closes when the upper plate 5 moves upward.

[0041] In this embodiment, the upward rotation direction of the upper plate 5 is the same as the direction from the movable end 73 to the hinge end 72 of the opening and closing plate 7; the downward rotation direction of the upper plate 5 is the same as the direction from the hinge end 72 to the movable end 73 of the opening and closing plate 7.

[0042] During operation, as the lower plate 4 drives the upper plate 5 downwards, the internal threaded hole 54 in the center of the upper plate 5 and the external thread 81 on the outer wall of the central rod 8 generate threaded transmission, causing the upper plate 5 to rotate. During the downward movement of the upper plate 5, it squeezes the water between the lower surface of the upper plate 5 and the inner bottom wall of the air outlet hood 2. The water flows upwards through the opening and closing groove 55 and pushes open the opening and closing plate 7 within the groove 55. Compared to the original method where water passes through the filter holes 71 on the opening and closing plate 7, this reduces the downward resistance of the upper plate 5 and... The reduced water flow and splashing within the air outlet hood 2 make the water inside the hood 2 more stable, preventing overflow. During the upward movement of the upper plate 5, a negative pressure is created between the bottom wall of the air outlet hood 2 and the lower surface of the upper plate 5. Under this negative pressure, the opening and closing plate 7 closes within the opening and closing groove 55. The movable end 73 of the opening and closing plate 7 is blocked and limited by the stop block 56. The upper surface of the opening and closing plate 7 is flush with the upper surface of the upper plate 5. During the upward movement of the upper plate 5, water above the upper plate 5 passes through the filter hole 71 and enters below the upper plate 5, filtering out impurities. The hole 71 blocks the filter; during the upward movement of the upper plate 5, it rotates, and the direction of rotation of the upper plate 5 is consistent with the direction from the movable end 73 to the hinge end 72 of the opening and closing plate 7. This makes it easier and faster for the opening and closing plate 7 to close in the corresponding opening and closing groove 55 after being pushed by the water flow under the rotation of the upper plate 5. Thus, during the upward movement of the upper plate 5, the opening and closing plate 7 closes in time, and as much as possible, it prevents impurities from directly passing through the opening and closing groove 55 and entering below the upper plate 5. During the downward movement of the upper plate 5, it also rotates, and the direction of rotation of the upper plate 5 is consistent with the direction from the hinge end 72 to the movable end 73 of the opening and closing plate 7. This makes it easier for the opening and closing plate 7 to be pushed open at a certain angle. With the rotation of the upper plate 5, the opening and closing plate 7 opens further under the push of the water flow, and the opening angle of the opening and closing plate 7 in the opening and closing groove 55 increases. This makes it easier for the water below the upper plate 5 to pass through the opening and closing groove 55 and enter above the upper plate 5, which facilitates the flow of water. The opening and closing plate 7 can react in time with the upward or downward movement of the upper plate 5 to meet the usage requirements.

[0043] Example 4: The height of the external thread 81 on the outer wall of the center rod 8 does not exceed that of the air outlet hood 2; when the upper surface of the upper plate 5 is not lower than the air outlet hood 2, the internal thread hole 54 in the center of the upper plate 5 is disengaged from the external thread 81 on the outer wall of the center rod 8.

[0044] During operation, as the upper plate 5 moves upward, it generates a helical drive through the internal threaded hole 54 and the external thread 81 on the outer wall of the central rod 8. This causes the upper plate 5 to rotate during its upward movement. With the upper surface of the upper plate 5 above the exhaust hood 2, the internal threaded hole 54 in the center of the upper plate 5 disengages from the external thread 81 on the outer wall of the central rod 8. This allows the upper plate 5 to continue rotating due to its own inertia without being restricted by the external thread 81 on the central rod 8, thereby improving the impurity removal effect on the upper surface of the upper plate 5 and allowing impurities and excess water to be better removed. After the internal threaded hole 54 in the center of the upper plate 5 disengages from the external thread 81 on the outer wall of the central rod 8, a gap is formed, and external air will enter below the upper plate 5 along the gap. In addition, while the upper plate 5 stops moving upward and can still rotate, the filter hole 71 will not form a negative pressure adsorption, making it easier for impurities on the filter hole 71 to be removed.

[0045] Example 5: The rectangular strip 63 and the rectangular groove 82 are slidably sealed together; the inner and outer walls of the square tube 3 are provided with a vent hole 35 at the lower position; the bottom of the rectangular groove 82 is connected to the wall of the square groove 21 and is provided with an L-shaped hole 83; when the upper surface of the upper plate 5 is flush with the upper end of the air outlet hood 2, the vent hole 35 and the L-shaped hole 83 are aligned.

[0046] During operation, with the upper surface of the upper plate 5 flush with the upper end of the air outlet hood 2, the vent holes 35 and L-shaped holes 83 on the inner and outer walls of the square tube 3 are aligned, allowing the gas in the first air outlet chamber 15 to enter the rectangular groove 82 along the vent holes 35 and L-shaped holes 83. This unlocks the rectangular strip 63 from the rectangular groove 82, allowing the mesh cover 62 to pull the rectangular strip 63 out of the rectangular groove 82. This allows the operator to clean the impurities in the collection section 6. After cleaning, the rectangular strip 63 is inserted back into the rectangular groove 82, and the square tube 3 and upper plate 5 continue to move upward. The vent holes 35 and L-shaped holes 83 are misaligned, and the rectangular groove 82 is sealed, locking the rectangular strip 63 inside and preventing it from being pulled out. Thus, the mesh cover 62 is locked. In other working positions within the air outlet hood 2 of the upper plate 5, the vent holes 35 are also misaligned with the L-shaped holes 83, keeping the mesh cover 62 locked during the operation of the fresh air conditioning equipment, thus improving safety.

[0047] Example 6: The upper surface of the upper plate 5 bulges upward; the cross-section of the upper surface of the upper plate 5 is arc-shaped; the lower surface of the lower plate 4 bulges downward; the cross-section of the lower surface of the lower plate 4 is arc-shaped.

[0048] During operation, the upper surface of the arc-shaped upper plate 5 can more easily break the water flow and reduce noise. The bulging upper plate 5 will make the gas discharged from the second air hole 53 more dispersed, so that the airflow can come into contact with the water in the air outlet hood 2 more dispersed, further improving the contact effect between gas and water. Similarly, the lower surface of the arc-shaped lower plate 4 can also more easily break the water flow and reduce noise.
