Description

Technical Field

[0001] This invention belongs to the field of fresh air treatment technology, specifically relating to an intelligent energy-saving fresh air treatment device. Background Technology

[0002] A fresh air system is an independent air handling system consisting of a supply air system and an exhaust air system. It is divided into two types: ducted fresh air systems and ductless fresh air systems. A ducted fresh air system consists of a fresh air unit and ductwork fittings. The fresh air unit purifies outdoor air and introduces it into the room, while the ductwork exhausts indoor air. A ductless fresh air system also consists of a fresh air unit, which purifies outdoor air and introduces it into the room. Relatively speaking, ducted fresh air systems are more suitable for industrial or large office areas due to the larger scale of the project, while ductless fresh air systems are more suitable for residential use due to their ease of installation.

[0003] Fresh air systems are a type of intelligent energy-saving fresh air treatment device. However, the cover plates of fresh air systems are mostly installed with bolts. When it is necessary to inspect and maintain the internal parts of the fresh air system installed on the ceiling, users need to climb ladders and use tools to turn multiple bolts to remove the cover plates, which makes disassembly and assembly time-consuming. Moreover, during the disassembly and assembly process, bolts and matching parts are easy to lose due to their small size. At the same time, the purification structure inside the fresh air system will accumulate a lot of impurities after long-term use. If it is not cleaned or replaced, it will reduce the working efficiency of the fresh air system. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent energy-saving fresh air treatment device to solve the above-mentioned problems.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0037] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0038] like Figures 1-9 As shown, an intelligent energy-saving fresh air handling device of the present invention includes:

[0039] The housing 1 has a ventilation assembly 2 and a purification assembly 4 inside its cavity, and a cover assembly 3 is provided on the top of the housing 1.

[0040] Ventilation component 2 is used to replace indoor air;

[0041] The cover assembly 3 is used to cover the access port on the top of the housing 1;

[0042] Purification component 4 is used to filter and sterilize the air.

[0043] like Figure 1 and Figure 2As shown, the ventilation assembly 2 includes an air inlet duct 201 connected to one side of the housing 1. An exhaust duct 202 is located directly behind the air inlet duct 201, with one end connected to the housing 1. An air supply duct 203 is connected to the other side of the housing 1, and a return duct 204 is located directly behind the air supply duct 203, with one end connected to the housing 1. A fan 205 is installed at two opposite corners of the inner cavity of the housing 1. The exhaust end of one fan 205 is connected to the exhaust duct 202, and the exhaust end of the other fan 205 is connected to the air supply duct 203. By using the two fans 205, the purpose of autonomous air supply and exhaust is achieved, enabling indoor air convection and maximizing indoor air exchange.

[0044] like Figure 2 As shown, a heat exchange element 206 is installed at the center of the inner cavity of the casing 1. The heat exchange element 206 is located between two fans 205. Each of the four corners of the heat exchange element 206 has a vertically arranged baffle 207. The side of the baffle 207 furthest from the heat exchange element 206 is fixedly connected to the inner wall of the casing 1. By utilizing the combined use of the heat exchange element 206 and the baffles 207, the energy in the exhaust gas is transferred to the introduced fresh air. In hot summer weather, this retains the energy of the indoor air conditioning; in winter heating, it retains the indoor temperature, achieving the purpose of recovering both cooling and heating energy.

[0045] like Figure 1-5 As shown, the cover assembly 3 includes a maintenance plate 301 that snaps onto the top opening of the housing 1. The tops of the heat exchange element 206 and the partition 207 are both attached to the bottom of the maintenance plate 301. Side strips 302 are movably arranged on both sides of the maintenance plate 301. Grooves 312 for the side strips 302 to move are formed on both sides of the maintenance plate 301. The maintenance plate 301 and the side strips 302 are perpendicular to each other. Insert blocks 303 are fixedly connected to the front and rear sides of the bottom of the side strips 302. A wedge block 304 is fixedly connected to the bottom end of the insert block 303. Insert holes 305 for inserting the insert blocks 303 are formed on both sides of the housing 1. A stop block 306 of equal height to the insert block 303 is fixedly connected to the inner cavity of the insert hole 305. The cover assembly 3 provides a seal for the housing 1, ensuring the normal operation of the intelligent energy-saving fresh air treatment device.

[0046] like Figure 5 and Figure 6 As shown, sliders 307 are fixedly connected to both the front and rear ends of the edge strip 302. Slots 308, adapted to the sliders 307, are provided on both the front and rear sides of the inner cavity of the groove 312. A spring 309 is fixedly connected to the inner cavity of the slot 308, and the other end of the spring 309 is fixedly connected to the slider 307. The cooperation of the sliders 307 and the slots 308 limits the movement of the edge strip 302, allowing it to move stably horizontally. Simultaneously, the spring 309 enables the edge strip 302 to automatically reset.

[0047] like Figure 1 , Figure 2 , Figure 3 , Figure 5 as well as Figure 6 As shown, a positioning strip 310 is horizontally and movably arranged in the inner cavity of the groove 312. One side of the positioning strip 310 contacts the inner wall of the groove 312, and the other side of the positioning strip 310 is rotatably connected to the top of the side strip 302. First finger grooves 311 communicating with the groove 312 are provided on both sides of the top of the inspection plate 301. The positioning strip 310 can position the side strip 302, keeping it stably in a certain state, which helps improve the stability of the connection between the inspection plate 301 and the housing 1. The first finger grooves 311 allow the user to flip and open the positioning strip 310.

[0048] like Figure 2 , Figure 7 , Figure 8 as well as Figure 9 As shown, the purification component 4 includes rectangular frames 401 located at two opposite corners of the inner cavity of the housing 1. Two partitions 207 along the length of the housing 1 are fixedly connected to the sides of their respective inner walls with limiting strips 402 of equal height to the heat exchange element 206. Each pair of limiting strips 402 forms a group, and there are four groups of limiting strips 402. The four corners of the rectangular frame 401 are respectively abutted against the surfaces of the corresponding two groups of limiting strips 402. Storage slots 403 are provided on both sides of the inner cavity of the rectangular frame 401, and filters 404 are embedded in the inner cavity of the storage slots 403. Second finger grooves 411 communicating with the storage slots 403 are provided on both sides of the top and bottom of the rectangular frame 401, allowing the user to remove the filters 404 from the inner cavity of the storage slots 403. The rectangular frame 401 filters the gas entering the inner cavity of the housing 1.

[0049] like Figure 7-9 As shown, the inner cavity of the rectangular frame 401 is provided with two parallel baffles 405, and ultraviolet lamps 406 are installed on opposite sides of the two baffles 405. By using the baffles 405 and ultraviolet lamps 406 together, the gas entering the inner cavity of the housing 1 can be sterilized.

[0050] like Figure 9 As shown, two symmetrical dovetail tenons 407 are fixedly connected to one side of the baffle plate 405, and a dovetail groove 408 is provided on the inner wall of the rectangular frame 401 for the dovetail tenons 407 to slide. By using the dovetail tenons 407 and the dovetail groove 408 together, the baffle plate 405 can be initially limited, effectively preventing the baffle plate 405 from tipping over.

[0051] like Figure 9As shown, an eccentric wheel 409 is rotatably connected to the side of the baffle 405 away from the ultraviolet lamp 406, and a positioning groove 410 adapted to the eccentric wheel 409 is provided on the inner wall of the rectangular frame 401. By using the cooperation of the eccentric wheel 409 and the positioning groove 410, the baffle 405 can be given a secondary limiting function, effectively preventing the baffle 405 from swaying under the action of wind.

[0052] Working principle of the invention:

[0053] First, by starting two fans 205, one fan 205 delivers outdoor air into the interior of the casing 1 and exchanges heat with indoor air through the heat exchange element 206 before exhausting it into the room through the exhaust pipe 202. The other fan 205 delivers indoor air into the interior of the casing 1 and exchanges heat with outdoor air through the heat exchange element 206 before exhausting it into the room through the supply pipe 203. At the same time, the air entering the interior of the casing 1 is filtered by the filter 404 inside the rectangular frame 401. The baffle 405 inside the rectangular frame 401 effectively reduces the air velocity within the rectangular frame 401. The ultraviolet lamp 406 sterilizes and disinfects the air entering the rectangular frame 401, preventing pollutants and bacteria in the air from being discharged into the room or outdoors.

[0054] Secondly, when it is necessary to inspect and maintain the internal components of the housing 1, the positioning strip 310 in the inner cavity of the groove 312 can be flipped upward and opened using the first finger groove 311, thereby unlocking the side strip 302. At this time, both hands hold the sides of the inspection plate 301 and push the two side strips 302 towards each other using the thumbs. The side strips 302 drive the insert block 303 and the wedge block 304 to move synchronously. The side strips 302 also drive the slider 307 to slide in the inner cavity of the slide groove 308. The spring 309 is compressed under force until the wedge block 304 is far away from the bottom of the stop block 306, thereby unlocking the inspection plate 301. Then, the inspection plate 301 is lifted upward. The inspection plate 301 drives the side strip 302, the insert block 303 and the wedge block 304 to move upward synchronously until the wedge block 304 is disengaged from the inner cavity of the insertion hole 305, thereby completing the disassembly operation of the housing 1 and the cover plate assembly 3.

[0055] Furthermore, pull the purification component 4 upwards to detach the rectangular frame 401 from the inner cavity of the housing 1. Then, use the second finger groove 411 to remove the filter 404 from the inner cavity of the storage slot 403 for cleaning or replacement. By turning the eccentric wheel 409 on the surface of the baffle plate 405, the eccentric wheel 409 rotates out of the inner cavity of the positioning slot 410, thus unlocking the baffle plate 405. Move the baffle plate 405 horizontally, and the baffle plate 405 will drive the dovetail tenon 407 to slide in the inner cavity of the dovetail groove 408 until the dovetail tenon 407 disengages from the inner cavity of the dovetail groove 408. This completes the disassembly of the rectangular frame 401 and the baffle plate 405, allowing the ultraviolet lamp 406 to be inspected.

[0056] Finally, after the maintenance is completed, the purification component 4 is inserted into the interior of the housing 1. Then, the inspection plate 301 is held and the wedge block 304 is inserted into the inner cavity of the insertion hole 305. After the inspection plate 301 moves down a certain distance, the top of the stop block 306 applies pressure to the wedge block 304. Under the action of the inclined surface of the wedge block 304, the wedge block 304 is forced to move horizontally in the direction of the first finger groove 311. The spring 309 is compressed until the inspection plate 301 is completely fitted with the top of the housing 1. Through the elastic restoring force of the spring 309, the insertion block 303 and the wedge block 304 are moved to their original state, and the wedge block 304 is located at the bottom of the stop block 306, thus completing the assembly of the housing 1 and the cover plate component 3.

[0057] In summary, this intelligent energy-saving fresh air handling device replaces the traditional bolt installation by using a plug-in connection between the housing 1 and the cover plate assembly 3. Disassembly is simple: just flip the positioning strip 310 upwards and move the two side strips 302 on the surface of the inspection plate 301 towards each other to unlock the inspection plate 301. Installation is straightforward: simply align the wedge block 304 with the insertion hole 305 and press it down to its maximum extent. The operation is simple and convenient, requiring no tools during the entire disassembly and assembly process, saving time and effort. Furthermore, the cover plate assembly 3 is a single unit, effectively preventing the loss of individual parts during disassembly and assembly. By adopting a split structure for the purification component 4, both filtration and sterilization functions are achieved, ensuring clean and healthy air entering the room. This also facilitates subsequent disassembly, classification, cleaning, or replacement of the purification component 4, improving cleaning efficiency and reducing replacement costs.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
