Description

Technical Field

[0003] However, the current fresh air devices mainly include ceiling-mounted fresh air devices, cabinet-type fresh air devices, wall-mounted fresh air devices and window ventilators. The air inlet and exhaust outlet heights of the above fresh air devices are fixed, and the problem of hot air floating up and cold air sinking is not considered. During the indoor and outdoor air exchange process, the higher temperature gas and the lower temperature gas in the indoor environment cannot be discharged according to demand, which may cause the rapid loss of one of the hot air and the cold air when the ventilation volume is large, affecting the indoor temperature stability.

[0020] In summary, this application has the following beneficial effects:

[0021] 1. The present application cooperates with a cabinet, a fresh air box, an old air discharge component, a fresh air introduction component, an air internal circulation component and a humidification component. During use, by controlling the working states of the old air discharge component, the fresh air introduction component and the air internal circulation component installed in the fresh air box at different heights, the air at different heights can be discharged from the room according to needs while the air is exchanged between the indoor and outdoor air, thereby reducing the loss of hot air in winter and cold air in summer caused by indoor air discharge, and moving the hot air downward or the cold air downward according to needs, so that the air temperature and humidity at different heights in the room are basically consistent, and in the process, heat is exchanged for the air entering the room, thereby further improving the stability of the indoor temperature and providing a more comfortable use experience for the residents;

[0022] 2. In the present application, through the cooperation of the first primary filter plate, the second primary filter plate and the high-efficiency filter plate, when the gas flows into the fresh air box, the first primary filter plate and the second primary filter plate can perform preliminary filtering on the dust particles in the gas, thereby trying to avoid the dust particles from entering the three-phase heat exchange component and causing the three-phase heat exchange component to be blocked. At the same time, the first primary filter plate can perform preliminary filtering on the air that will enter the room through the fresh air introduction component. When the indoor air is circulated internally through the air internal circulation component, the second primary filter plate can first perform preliminary filtering on the air entering the circulating air box, and after these two parts of gas pass through the fresh air introduction component and the air internal circulation component respectively, they are both filtered twice through the high-efficiency filter plate, and then discharged into the room from the air inlet box, thereby effectively ensuring the overall indoor air quality;

[0023] 3. This application uses the cooperation of dehumidification plates and humidification components. During the air circulation process, when the indoor air is high (such as the dry external environment in winter, people cooking hot pot indoors causing high indoor humidity, etc.), the air passing through the circulating air box first passes through the dehumidification plate to reduce the humidity, thereby minimizing the condensation of water droplets inside the three-phase heat exchange component due to excessive indoor air humidity and affecting the gas passage effect. After this part of the gas has been heat exchanged by the three-phase heat exchange component and passed through the humidification component, the air is humidified again, thereby achieving more precise control of the indoor air humidity. When the indoor humidity is high and causes discomfort to the human body, the atomizer can be turned off, thereby continuously reducing the indoor humidity during the indoor air circulation process.

[0024] 4. This application uses the cooperation of the first primary filter plate, the dust-proof pipe and the two-way connecting pipe to enable the staff to clean the connecting part between the first primary filter plate and the external environment (i.e., the inside of the dust-proof pipe and the two-way connecting pipe) while replacing the first primary filter plate, thereby minimizing the accumulation of pollutants near the first primary filter plate and seriously reducing the service life and filtering effect of the first primary filter plate.

[0051] Reference Figure 7 , Fig.12 and Fig.13The inner side walls of the cabinet 1 are located on both sides of the new air box 2, and are respectively fixedly connected with a circulating air box 12 connected to the first connecting pipe 8 and an exhaust air box 13 connected to the first old air chamber 31. A dehumidification plate 14 slidably connected to the cabinet 1 and the circulating air box 12 is inserted inside the circulating air box 12. The exhaust air box 13 and the circulating air box 12 are both inserted with a second primary filter plate 15 slidably connected to the cabinet 1, the exhaust air box 13 and the circulating air box 12.

The outer wall of the plate is close to the cabinet 1 and is provided with a U-shaped groove. The circulating air box 12 and the exhaust box 13 are connected to the indoor environment on one side near the cabinet 1. When the old air guide fan 33 is turned on, the indoor air passes through the exhaust box 13 and is filtered by the second primary filter plate 15 in the exhaust box 13 before flowing into the first old air cavity 31, and then enters the first old air cavity 31 and is discharged to the outdoors.

[0052] Reference Figure 3 and Fig.14 A water storage box 16 is provided on one side of the outer wall of the cabinet 1 close to the circulating air box 12, and a drainage hole 17 connected to the water storage box 16 is provided on the inner bottom wall of the circulating air box 12.

The water in the circulating air box 12 can naturally flow into the water storage box 16 through the drainage hole 17 (the water storage box 16 should be a box with an open top, and use a transparent material such as transparent resin, transparent plastic, etc., so that the user can observe the water height in the water storage box 16).

[0053] Reference Figure 2 , Fig.15 and Fig.16 The three-phase heat exchange component 6 includes a heat exchange cover plate 61 and a heat exchange bottom plate 62. A plurality of heat exchange components are evenly arranged between the heat exchange cover plate 61 and the heat exchange bottom plate 62 along the height direction. Each group of heat exchange components includes a first heat exchange plate 63 for connecting the first circulating air cavity 51 and the second circulating air cavity 52, a second heat exchange plate 64 arranged above the first heat exchange plate 63 for connecting the first fresh air cavity 42 and the second fresh air cavity 43, and a third heat exchange plate 65 arranged above the second heat exchange plate 64 for connecting the first old air cavity 31 and the second old air cavity 32. The plurality of heat exchange components are stacked, and a heat insulation plate 66 is arranged between each group of heat exchange components.

[0054] The implementation principle of the present application is as follows: when in use, turn on the old air guide fan 33 and the fresh air guide fan 44. At this time, the indoor exhaust gas is first drawn into the second old air chamber 32 connected to the indoor environment, and then enters the first old air chamber 31, and is discharged to the outside through the old air guide fan 33 and the exhaust pipe 18. At the same time, the external air passes through the circular air inlet box 41 and first enters the second fresh air chamber 43, and then enters the first fresh air chamber 42, and enters the air inlet of the fresh air guide fan 44 in the first fresh air chamber 42. The gas entering the air inlet of the fresh air guide fan 44 first flows into the air inlet box 10 through the exhaust port of the fresh air guide fan 44, and is discharged into the air inlet box 10 connected to the air inlet box 10 after passing through the high-efficiency filter plate 11. In a well-ventilated indoor environment, when external air flows through the circular air inlet box 41, the first primary filter plate 45 filters large dust particles that may exist in the air, and minimizes the large dust particles that follow the gas into the fresh air box 2 (after the large dust particles enter the fresh air box 2, they may adhere to the three-phase heat exchange component 6, and then may affect the heat exchange effect of the three-phase heat exchange component 6). When the air flows through the high-efficiency filter plate 11, the high-efficiency filter plate 11 filters smaller particles and pollutants in the gas, including microorganisms such as viruses and bacteria, to effectively ensure the quality of the air flowing into the indoor space, thereby discharging indoor exhaust gas to the outdoor environment, and continuously introducing external air into the room to exchange the air for the room.

[0055] When the air flowing through the old air discharge component 3, the new air introduction component 4 and the air internal circulation component 5 passes through the three-phase heat exchange component 6, the outdoor air passes through the second heat exchange plate 64 and exchanges heat with the second heat exchange plate 64 when entering the first fresh air cavity 42 from the second fresh air cavity 43, a part of the indoor air passes through the third heat exchange plate 65 and exchanges heat with the third heat exchange plate 65 when flowing from the first old air cavity 31 into the second old air cavity 32, and another part of the indoor air passes through the first heat exchange plate 63 and exchanges heat with the first heat exchange plate 63 when flowing from the first circulation air cavity 51 into the second circulation air cavity 52. ​​The first heat exchange plate 63 and the third heat exchange plate 65 both exchange heat with the second heat exchange plate 64, thereby making the indoor air flowing through the three-phase heat exchange component 6 indirectly exchange heat with the outdoor air, and the heat insulation plate 66 can try to avoid direct heat exchange between the adjacent first heat exchange plate 63 and the third heat exchange plate 65.

[0056] If the indoor temperature needs to be lower than the outdoor temperature (in summer, the air conditioner is kept in cooling mode to make the average indoor temperature lower than the average outdoor temperature), the old air guide fan 33 and the new air guide fan 44 in the new air box 2 near the top wall of the cabinet 1 are turned on, and the circulating air guide fan 53 near the bottom wall of the cabinet 1 is turned on at the same time. Since hot air naturally floats up and cold air naturally sinks, the old air guide fan 33 near the top wall of the cabinet 1 will first pass the high-temperature gas at a higher height in the room through the exhaust box 13, the first old air cavity 31, and the third heat exchange plate 6. 5 is sucked into the second old air cavity 32, and discharged to the outside through the old air guide fan 33 and the exhaust pipe 18 in the second old air cavity 32. The air at the bottom with lower temperature enters the first connecting pipe 8 with an opening close to the inner bottom wall of the cabinet 1 after passing through the circulating air box 12 close to the inner bottom wall of the cabinet 1, and enters the first circulating air cavity 51 close to the inner top wall of the cabinet 1. After passing through the first heat exchange plate 63, the gas flows into the second circulating air cavity 52 connected to the first circulating air cavity 51, and then passes through the second connecting pipe 9 and the second connecting pipe 9 close to the inner top wall of the cabinet 1. The circulating air guide fan 53 and the air inlet box 10 on the bottom wall of the cabinet 1 are discharged back into the room. At the same time, the outdoor air first enters the circular air inlet box 41, then flows into the second fresh air cavity 43 near the inner top wall of the cabinet 1, and then flows into the first fresh air cavity 42 near the inner top wall of the cabinet 1 through the second heat exchange plate 64, and is discharged into the room through the fresh air guide fan 44 and the air inlet box 10. In this process, the indoor air flowing through the old air discharge component 3 and the air internal circulation component 5 continuously exchanges heat with the outdoor air flowing through the fresh air introduction component 4 whose temperature is higher than the indoor temperature through the three-phase heat exchange component 6, thereby effectively reducing the temperature of the outdoor air entering the room (since the air flowing through the air internal circulation component 5 is a gas with a lower temperature located at the bottom of the room, the cooling effect on the outdoor air entering the room is more obvious). At the same time, the air with a lower temperature is heat exchanged with the air entering the room and then discharged at a higher height in the room. Under the condition of not affecting the average indoor temperature as much as possible, the temperature at different heights in the room is made more balanced, and the temperature of the air discharged from the room is ensured to be relatively high, thereby improving the comfort of indoor personnel.

[0057] If the indoor temperature needs to be higher than the outdoor temperature (in winter, the air conditioner is kept in heating mode so that the average indoor temperature is higher than the average outdoor temperature), the old air guide fan 33 and the fresh air guide fan 44 in the fresh air box 2 near the bottom wall of the cabinet 1 are turned on, and the circulating air guide fan 53 near the top wall of the cabinet 1 is turned on at the same time, so that the indoor air flowing through the old air discharge component 3 and the air internal circulation component 5 continuously exchanges heat with the outdoor air flowing through the fresh air introduction component 4 whose temperature is lower than the indoor temperature through the three-phase heat exchange component 6, thereby effectively raising the temperature of the outdoor air entering the room (since the air flowing through the air internal circulation component 5 is a gas with a higher temperature located at a high position in the room, the cooling effect on the outdoor air entering the room is more obvious). At the same time, the air with a higher temperature is heat exchanged with the air entering the room and then discharged at a lower height in the room. Under the condition of not affecting the average indoor temperature as much as possible, the temperature at different heights in the room is made more balanced, and the temperature of the air discharged from the room is ensured to be relatively low, thereby improving the comfort of the indoor personnel.

[0058] When the indoor air humidity is high but the outdoor air humidity is lower than the indoor air (such as the dry external environment in winter, people cooking hot pot indoors causing high indoor humidity, etc.), the power of the old air guide fan 33, the new air guide fan 44 and the circulating air guide fan 53 can be increased to reduce the indoor humidity by increasing the air exchange volume. At the same time, when the indoor air is circulated internally through the air internal circulation component 5, while this part of the indoor air passes through the circulating air box 12, the dehumidification plate 14 adsorbs the gas in the air to reduce the humidity of the air during the internal circulation process, thereby further reducing the indoor air humidity.

[0059] When the indoor humidity is low (for example, the indoor humidity is reduced due to the air conditioner being turned on for a long time in winter and summer), the circulating air guide fan 53 is turned on and the atomizer 73 is turned on at the same time. The atomizer 73 atomizes the moisture inside the water tank 72 and discharges it into the humidification chamber 71. Since the humidification chamber 71 is connected to the second connecting pipe 9, when the gas passes through the second connecting pipe 9, the humidity of the gas is increased by the atomized water vapor in the humidification chamber 71, thereby increasing the overall humidity of the indoor air during the circulation process.

[0060] When the outdoor air humidity is high (such as the return of the south wind season in the southern region), the power of the old air guide fan 33 and the fresh air guide fan 44 is reduced, and the power of the circulating air guide fan 53 is increased and the atomizer 73 is in the closed state. At this time, the reduction of indoor air humidity is mainly achieved through the internal circulation of the air internal circulation component 5. When this part of the indoor air passes through the circulating air box 12, the dehumidification plate 14 adsorbs the gas in the air to reduce the humidity of the air during the internal circulation process.

[0061] When the old air guide fan 33 is turned on, the indoor air passes through the exhaust box 13 and is filtered by the second primary filter plate 15 in the exhaust box 13 before flowing into the first old air cavity 31, and then enters the first old air cavity 31 and is discharged to the outdoors. In this process, the air that is about to flow through the exhaust box 13 can be filtered, thereby avoiding dust accumulation in the device as much as possible (most of the dust is adsorbed and isolated in the second primary filter plate 15 located in the exhaust box 13). When the circulating air guide fan 53 is turned on, the indoor air first passes through the circulating air box 12 and is filtered and adsorbed by the second primary filter plate 15 and the dehumidification plate 14 (in this process, the air is first adsorbed with particulate dust by the second primary filter plate 15, and then adsorbed with moisture in the air by the dehumidification plate 14, which can avoid dust particles adhering to the surface of the adsorbent in the dehumidification plate 14 and affecting the moisture absorption effect of the dehumidification plate 14). When the adsorption state of the adsorbent in the dehumidification plate 14 tends to be saturated, part of the moisture adsorbed by the dehumidification plate 14 flows downward and flows into the water storage box 16 through the drainage hole 17.

[0062] After the device has been used for a long time, the first primary filter plate 45, the high-efficiency filter plate 11 and the second primary filter plate 15 may be blocked, and the dehumidification plate 14 may reach its moisture absorption limit. When the first primary filter plate 45 is blocked, the staff first removes the bolts threadedly installed in the threaded holes, then opens the closing cover 47, and removes the first primary filter plate 45 through the opening 46. At the same time, since the device continuously draws fresh air from the external environment, some dust and debris in the air may adhere to the inner wall of the dust protection pipe 20 (the setting of the dust protection pipe 20 can avoid dust from directly adhering to the intake pipe 19 as much as possible, causing cleaning difficulties). Some large particles and debris that cannot pass through the first primary filter plate 45 are also accumulated on the inner wall of the two-way connecting pipe 21 near the first primary filter plate 45. If only the first primary filter plate 45 is replaced at this time without cleaning the dust protection pipe 20 and the two-way connecting pipe 21 in time, the dust protection pipe 20 and the two-way connecting pipe 21 will accumulate. The accumulated pollutants will still follow the gas flowing from the outdoors into the indoors into the circular air inlet box 41, thereby affecting the service life of the first primary filter plate 45 after replacement. When the staff takes out the first primary filter plate 45, the two-way connecting pipe 21 threadedly connected to the first primary filter plate 45 and the dust protection pipe 20 threadedly connected to the two-way connecting pipe 21 are taken out together with the first primary filter plate 45, and then the first primary filter plate 45, the dust protection pipe 20 and the two-way connecting pipe 21 are disassembled from each other, and the dust protection pipe 20 and the two-way connecting pipe 21 are cleaned. After replacing the first primary filter plate 45, the first primary filter plate 45, the dust protection pipe 20 and the two-way connecting pipe 21 are reinstalled on each other, and the first primary filter plate 45, the dust protection pipe 20 and the two-way connecting pipe 21 installed on each other are reset through the opening 46 until the dust protection pipe 20 is slidably connected to the air inlet pipe 19, and the first primary filter plate 45 is slidably connected to the circular air inlet box 41 to complete the cleaning and replacement.

[0063] When the high-efficiency filter plate 11 and the second primary filter plate 15 are blocked, the high-efficiency filter plate 11 and the second primary filter plate 15 can be directly pulled out and replaced from the air inlet box 10, the circulating air box 12 and the exhaust air box 13 through the U-shaped groove. When the dehumidification plate 14 reaches the adsorption limit, the dehumidification plate 14 can also be directly pulled out and replaced from the circulating air box 12 through the U-shaped groove.

[0064] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
