Description

Technical Field

[0001] The invention relates to the technical field of energy-saving ventilation equipment, in particular to an energy-saving ventilation system for removing formaldehyde in a building. Background Art

[0002] With the continuous advancement of modern building technology, people's requirements for indoor environmental quality are also increasing. However, the widespread presence of harmful gases such as formaldehyde in newly renovated buildings has become a problem that cannot be ignored. These gases mainly come from building materials, decorative materials and furniture, etc. They not only have pungent odors, but also pose a serious threat to human health. Long-term exposure to these harmful gases may also lead to more serious health problems.

[0003] As an effective way to achieve indoor and outdoor air exchange without opening windows, the ventilation system has gradually attracted people's attention. By introducing fresh air from outdoors and expelling dirty air from indoors, the concentration of indoor formaldehyde and other harmful gases can be effectively reduced, thereby improving indoor air quality. However, as the main equipment in the ventilation system, the fresh air ventilator has certain challenges and shortcomings in maintenance.

[0004] In the prior art, during the maintenance of traditional fresh air ventilators, the main focus is on the cleaning and replacement of the heat exchange core, but the cleaning of the corresponding air vents is often neglected. Since the air vents are arranged on both sides of the heat exchange core, the outdoor fresh air is introduced into the room after passing through the heat exchange core. During this process, impurities in the outside air accumulate for a long time and adhere to both sides of the heat exchange core, blocking the air vents, thereby causing poor air intake, which not only affects the heat exchange effect of the heat exchange core, but also reduces the ventilation effect of the fresh air ventilator.

[0005] Therefore, an energy-saving ventilation system for removing formaldehyde from indoor buildings is needed to solve the problem that in the existing ventilation system, the vents cannot be cleaned in time during maintenance of the fresh air ventilator, resulting in long-term accumulation of impurities, thereby affecting the exchange effect of the heat exchange core and reducing the ventilation effect.

DETAILED DESCRIPTION

[0038] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Example 1: Please refer to Figures 1 to 18 The present invention provides a technical solution: an energy-saving ventilation system for removing formaldehyde in a building, comprising a fresh air ventilator 1, a baffle 2, a heat exchange core 3, a support frame 4 and a vent 5, wherein the baffle 2 and the heat exchange core 3 are both two, two slide grooves 6 are provided on the left and right sides of the top of the support frame 4, a slider 7 is installed on the inner wall of the slide groove 6, a support plate 8 is installed on the adjacent side of the sliders 7 on the left and right sides, a brush 14 is installed on the side of the support plate 8 close to the vent 5, a scraping frame 12 is installed on the bottom of the support plate 8, a limiting block 20 is plugged into the upper part of the slider 7, limiting grooves 36 are provided on the left and right sides of the heat exchange core 3, and the adjacent sides of the limiting blocks 20 on the left and right sides are plugged into the inner wall of the limiting groove 36, the bottom of the support plate 8 is slidably connected to the bottom wall of the support frame 4, and the front and rear support plates 8 are plugged into the middle inner wall of the support frame 4, and the front and rear bottom walls of the support frame 4 are connected to the inner wall of the middle inner wall of the support frame 4. Two discharge grooves 30 are provided on both sides, and collection frames 9 are inserted on the front and rear sides of the bottom of the supporting frame 4, and the scraping frame 12 is slidably connected to the inner wall of the discharge groove 30; the brushes 14 on the left and right sides are symmetrically arranged, so that the brushes 14 are used to wipe the air holes 5 to reduce the dust residue on the surface thereof, and at the same time increase the ventilation effect of the fresh air exchanger 1, and the collection frame 9 is inserted at the bottom of the two discharge grooves 30, so that when the impurities fall downward along the inclined surface of the supporting frame 4, they fall into the interior of the collection frame 9 through the discharge groove 30 for subsequent cleaning, and the limiting blocks 20 on the left and right sides are inserted into the inner wall of the movable groove 21, and the adjacent ends are penetrated by the slider 7, and the front and rear sides of the limiting block 20 are arc surfaces, so that when the heat exchange core 3 is pulled forward and backward, the limiting block 20 is driven, and the slider 7 is pulled to move at the same time, and the inclined surface is used to facilitate the automatic separation between the heat exchange core 3 and the limiting block 20.

[0040] At first, the baffles 2 on the front and rear sides are removed, and then the heat exchange core 3 is pulled to the front and rear sides respectively, so that it moves backward along the middle part of the support frame 4. Since the slider 7 is inserted into the inner wall of the limiting groove 36 and the support frame 4 through the support plate 8, the sliders 7 on the front and rear sides are driven to slide backward along the inner wall of the slide groove 6. In this process, the support plate 8 follows the movement of the slider 7 to slide on the surface of the support frame 4, and then drives the brush 14 to clean the surface of the support frame 4 to reduce impurities on the surface of the vent hole 5. After cleaning, the sliders 7 on the front and rear sides are driven to move toward each other, and the brush 14 is driven to wipe the surface of the support frame 4 again, thereby improving the cleaning effect of the surface of the support frame 4 and reducing impurities remaining on the surface of the vent hole 5. At the same time, since the scraping frame 12 at the bottom of the support plate 8 slides along the inner wall of the discharge groove 30, it not only increases the stability of the support plate 8 when moving, but also can scrape the inner wall of the discharge groove 30, and scrape the cleaned dust to the inner wall of the collection frame 9 for subsequent cleaning.

[0041] Embodiment 2: On the basis of embodiment 1, in order to realize the reset of the sliding block 7 along the inner wall of the slide groove 6, a fixing rod 37 is installed on the inner wall of the slide groove 6, and two receiving grooves 10 are provided on the left and right sides of the upper part of the support frame 4, and a tension spring 11 is installed on the inner wall of the receiving groove 10; the fixing rod 37 is inserted into the lower part of the sliding block 7, so that the sliding block 7 can move more smoothly on the inner wall of the slide groove 6, thereby increasing the stability of its movement, and the separated sides of the tension springs 11 on the front and rear sides are installed between the sliding block 7, and the receiving groove 10 is connected with the slide groove 6, so that when the sliding blocks 7 on both sides move in opposite directions, the tension spring 11 is pulled to penetrate the slide groove 6, so that the elastic force thereof can be used to drive the sliding block 7 to reset.

[0042] First, pull the heat exchange core 3 toward the front and rear sides respectively, and let it move backward along the middle part of the support frame 4. Since the slider 7 is inserted into the inner wall of the limiting groove 36 through the support plate 8 and is assembled between the support frame 4, the sliders 7 on the front and rear sides are driven to slide backward along the inner wall of the slide groove 6 and stretch the tension spring 11. When the heat exchange core 3 is removed, the slider 7 can be released, and the elastic force of the tension spring 11 can be used to pull the sliders 7 on the front and rear sides to move toward each other, and drive the front and rear support plates 8 to reset, so as to drive the brush 14 to reset.

[0043] Embodiment 3: On the basis of embodiment 2, in order to increase the cleaning liquid, improve the cleaning effect of the brush 14, and facilitate the collection of waste liquid, a storage groove 26 is provided inside the slider 7, a connecting hole 15 is provided at the top of the storage groove 26, a sealing cover 16 is inserted at the top of the inner wall of the connecting hole 15, and the sealing cover 16 is opened upwards to facilitate the addition of cleaning liquid into the storage groove 26, an output groove 27 is provided at the bottom of the storage groove 26, a piston 28 is inserted at the inner wall of the output groove 27, an output hole 29 is provided in the middle of the piston 28, a connecting plate 23 is installed on the top of the piston 28, a through groove 22 is provided inside the side of the slider 7 close to the support plate 8, a conveying groove 24 is provided inside the separated side of the left and right support plates 8, a plurality of drainage holes 25 are provided at the bottom of the conveying groove 24, and a plurality of drainage grooves 13 are provided on the separated side of the left and right support plates 8; The connecting plate 23 is slidably connected to the inner wall of the through groove 22, so that when the limiting block 20 is disengaged from the limiting groove 36, the connecting plate 23 is used to drive the piston 28 to move, and then the output hole 29 is used to maintain the connection between the storage groove 26 and the conveying groove 24, so that the subsequent cleaning liquid can be discharged along the drainage hole 25. The adjacent ends of the pistons 28 on the left and right sides penetrate the slider 7 and are inserted into the inner wall of the conveying groove 24, so that the output groove 27 is blocked by the piston 28 to prevent the cleaning liquid from flowing out. The drainage hole 25 is connected to the drainage groove 13, and the bottom end of the drainage groove 13 is set at the top of the scraping frame 12, so that the cleaning liquid flows out through the drainage hole 25 and flows down along the inner wall of the drainage groove 13. At the same time, due to gravity, the excess cleaning liquid on the inner wall of the drainage groove 13 will drip downward to the surface of the support frame 4, thereby increasing the cleaning effect of the brush 14 when cleaning the vent 5.

[0044] After cleaning, push the connecting plate 23 to slide along the inner wall of the through groove 22, and pull the pistons 28 on the left and right sides to move in the opposite direction along the inner wall of the output groove 27, and then use the output hole 29 to keep the storage groove 26 and the delivery groove 24 connected, and deliver the cleaning liquid on the inner wall of the storage groove 26 to the inner wall of the delivery groove 24 through the output hole 29. After the heat exchange core 3 is disassembled, push the limiting block 20 to reset, and then release the slider 7, so as to use the elastic force of the tension spring 11 to pull the sliders 7 on the front and rear sides to move toward each other, and drive the brush 14 to wipe the surface of the support frame 4 again. However, in this process, the drainage hole 25 will deliver the cleaning liquid to the inner wall of the delivery groove 24. The cleaning liquid inside the groove 24 is guided downward to the inner wall of the drainage groove 13, and due to gravity, the cleaning liquid will fall to the surface of the support frame 4, so that the brush 14 can increase the cleaning liquid during cleaning to improve the cleaning effect of the surface of the support frame 4 and reduce the impurities remaining on the surface of the vent 5. At the same time, the scraping frame 12 slides along the inner wall of the discharge groove 30 to scrape the inner wall of the discharge groove 30, and scrape the cleaned dust to the inner wall of the collection frame 9. Since the bottom of the drainage groove 13 is set at the top of the scraping frame 12, the cleaning liquid remaining on the inner wall of the drainage groove 13 is guided to the inner wall of the collection frame 9, thereby facilitating the cleaning of waste liquid and impurities.

[0045] Embodiment 4: On the basis of embodiment 3, in order to facilitate the removal of the restriction between the restriction block 20 and the restriction groove 36 and to replenish the cleaning liquid in the conveying groove 24, a movable groove 21 is provided on the upper inner side of the slider 7, and a limit plate 19 is installed on the inner wall of the movable groove 21. The separated sides of the limit plates 19 on the left and right sides are both installed with elastic members 18, and a shifting block 17 is installed on the top of the limit plate 19; the separated sides of the elastic members 18 on the left and right sides are both installed on the inner wall of the movable groove 21, so that the elastic force of the elastic member 18 is utilized to facilitate pushing one side of the restriction block 20 into the inner wall of the restriction groove 36. The wall is used to fit the slider 7 and the heat exchange core 3. The shift block 17 is slidably connected to the top of the slider 7. The adjacent sides of the left and right limit plates 19 are installed between the limit block 20, so that the limit plate 19 is driven to move by pushing the shift block 17, thereby driving the limit block 20 to disengage from the limit groove 36. The bottom end of the limit plate 19 is installed between the connecting plate 23, and the movable groove 21 and the through groove 22 are connected. Therefore, when the restriction between the limit block 20 and the limit groove 36 is released, the connecting plate 23 can also be used to drive the piston 28 to move to guide the cleaning liquid on the inner wall of the storage tank 26 to the conveying tank 24.

[0046] The shifting block 17 is pulled to the left and right sides respectively, driving the limit plate 19 to slide along the inner wall of the movable groove 21, and driving the limit block 20 to disengage from the limit groove 36, and squeezing the elastic member 18 at the same time, thereby releasing the restriction between the heat exchange core 3 and the slider 7, so as to disassemble the heat exchange core 3. When the limit plate 19 moves, it will drive the connecting plate 23 at its bottom to slide along the inner wall of the through groove 22, and at the same time pull the pistons 28 on the left and right sides, and then use the output hole 29 to keep the storage groove 26 and the conveying groove 24 connected, and convey the cleaning liquid on the inner wall of the storage groove 26 to the inner wall of the conveying groove 24 through the output hole 29. After the heat exchange core 3 is disassembled, the shifting block 17 is released, so that the elastic force of the elastic member 18 is used to push the limit block 20 to reset, thereby releasing the restriction between the limit block 20 and the limit groove 36, and at the same time replenishing the cleaning liquid in the conveying groove 24.

[0047] Embodiment 5: On the basis of embodiment 4, in order to facilitate the cleaning of collected impurities and waste liquid, a movable groove 2 33 is provided inside the separated side of the front and rear collecting frames 9, and a plug plate 34 is inserted into the inner wall of the movable groove 233, and a plurality of elastic members 2 32 are installed at the bottom of the plug plate 34. Two auxiliary grooves 35 are provided on the separated side of the front and rear collecting frames 9, and buttons 31 are inserted into the inner wall of the auxiliary groove 35; the adjacent sides of the buttons 31 on the left and right sides penetrate the movable groove 23 and fit with the plug plate 34. By pressing the buttons 31 on both sides, the plug plate 34 is driven to shrink downward to the inner wall of the movable groove 23 and squeeze the plurality of elastic members 2 32. The bottom end of the elastic member 2 32 is installed on the inner bottom wall of the movable groove 23, and the top of the plug plate 34 penetrates the collecting frame 9 and is plugged into the supporting frame 4, so that the collecting frame 9 and the supporting frame 4 are assembled, and it is convenient for subsequent cleaning and use.

[0048] When it is necessary to clean the collection frame 9, first open the front and rear side baffles 2, then press the buttons 31 on both sides respectively to move toward each other along the inner wall of the auxiliary groove 35, and push the plug plate 34 downward to the inner wall of the movable groove 2 33, and at the same time squeeze the elastic member 2 32. At this time, the top of the plug plate 34 is separated from the support frame 4, releasing the restriction on the collection frame 9, and then the collection frame 9 can be pulled to the front and rear sides respectively to clean it. After completion, it is plugged into the bottom of the support frame 4 and installed at the bottom of the two discharge grooves 30 to collect the cleaned impurities and waste liquid, and then release the buttons 31 on both sides, so as to use the elastic force of the elastic member 2 32 to push the plug plate 34 upward, so that its top is fitted between the support frame 4, so as to jam the collection frame 9 between the support frame 4, and facilitate subsequent cleaning.

[0049] Embodiment 6: Based on Embodiment 5, a method for using an energy-saving ventilation system for removing formaldehyde in a building is proposed, and the method comprises the following steps:

[0050] Step 1: First, remove the baffles 2 on the front and rear sides, and then pull the heat exchange core 3 to the front and rear sides respectively, so that it moves backward along the middle of the support frame 4. Since the slider 7 is inserted into the inner wall of the limiting groove 36 and the support frame 4 through the support plate 8, the sliders 7 on the front and rear sides are driven to slide backward along the inner wall of the slide groove 6 and stretch the tension spring 11. In this process, the support plate 8 follows the movement of the slider 7 and slides on the surface of the support frame 4, thereby driving the brush 14 to clean the surface of the support frame 4 and reduce impurities on the surface of the vent 5.

[0051] Step 2, when cleaning is completed, pull the shift block 17 to the left and right sides respectively, drive the limit plate 19 to slide along the inner wall of the movable groove 21, and drive the limit block 20 to disengage from the limit groove 36, and squeeze the elastic member 18 at the same time, so as to release the restriction between the heat exchange core 3 and the slider 7, so as to disassemble the heat exchange core 3, and when the limit plate 19 moves, it will drive the connecting plate 23 at its bottom to slide along the inner wall of the through groove 22, and at the same time pull the pistons 28 on the left and right sides to move back to the inner wall of the output groove 27, and then use the output hole 29 to keep the storage groove 26 and the conveying groove 24 connected, and convey the cleaning liquid on the inner wall of the storage groove 26 to the inner wall of the conveying groove 24 through the output hole 29, and after the heat exchange core 3 is disassembled, release the shift block 17, so as to use the elastic force of the elastic member 18 to push the limit block 20 to reset, and then release the slider 7, so as to use the elastic force of the tension spring 11, Pull the sliders 7 on the front and rear sides to move toward each other, and drive the brush 14 to wipe the surface of the support frame 4 again. However, in this process, the drainage hole 25 will guide the cleaning liquid in the conveying groove 24 downward to the inner wall of the drainage groove 13, and due to gravity, the cleaning liquid will fall to the surface of the support frame 4, thereby allowing the brush 14 to increase the cleaning liquid during cleaning, so as to improve the cleaning effect of the surface of the support frame 4 and reduce impurities remaining on the surface of the vent hole 5. At the same time, since the scraping frame 12 at the bottom of the support plate 8 slides along the inner wall of the discharge groove 30, it not only increases the stability of the support plate 8 when moving, but also can scrape the inner wall of the discharge groove 30, and scrape the cleaned dust to the inner wall of the collection frame 9. At the same time, since the bottom of the drainage groove 13 is set at the top of the scraping frame 12, the cleaning liquid remaining on the inner wall of the drainage groove 13 is guided to the inner wall of the collection frame 9, thereby facilitating the cleaning of waste liquid and impurities.

[0052] Step 3, when the slider 7 is completely reset, the heat exchange core 3 after maintenance is inserted into the middle of the support frame 4. Since the two sides of the limiting block 20 are arc surfaces, the limiting block 20 is squeezed and pushed to shrink to the inner wall of the movable groove 21. When the heat exchange core 3 is completely reset, the elastic force of the elastic member 18 is used to drive the limiting block 20 and the limiting groove 36 to be assembled, and the stability of the heat exchange core 3 after assembly is increased, so that the impurities on the surface of the vent hole 5 are cleaned to keep it unobstructed, and the cleaning liquid is used to increase the cleaning effect, thereby improving the ventilation effect of the fresh air ventilator 1, increasing the air quality, and at the same time improving the heat exchange effect of the heat exchange core 3, and improving the energy saving and overall ventilation effect of the fresh air ventilator 1;

[0053] Step 4. When it is necessary to clean the collection frame 9, first open the front and rear side baffles 2, then press the buttons 31 on both sides respectively to move toward each other along the inner wall of the auxiliary groove 35, and push the plug plate 34 downward to the inner wall of the movable groove 2 33, and at the same time squeeze the elastic member 2 32. At this time, the top of the plug plate 34 is separated from the support frame 4, releasing the restriction on the collection frame 9, and then the collection frame 9 can be pulled to the front and rear sides respectively to clean it. After completion, it is plugged into the bottom of the support frame 4 and installed at the bottom of the two discharge grooves 30 to collect the cleaned impurities and waste liquid, and then release the buttons 31 on both sides, so as to use the elastic force of the elastic member 2 32 to push the plug plate 34 upward, so that its top is fitted between the support frame 4, so as to jam the collection frame 9 between the support frame 4, and facilitate subsequent cleaning.

[0054] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
