Description

Technical Field

[0001] The present invention relates to the field of fresh air equipment, and in particular to an air outlet structure and fresh air equipment. Background Art

[0002] Fresh air fans are devices that transport outdoor air into indoor areas. They have a wide range of applications and need to be installed for indoor and outdoor ventilation in both the south and the north.

[0003] When the climate is cold, especially in winter in the north, due to the low outdoor temperature, users are generally equipped with heating equipment indoors, resulting in a large temperature difference between indoors and outdoors. When the fresh air is introduced by the fresh air fan, condensation is easy to form at the air outlet grille in the fresh air fan unit. When condensation water is generated at the air outlet grille of the fresh air fan unit for a long time, it will have a certain impact on the indoor environment, and there are also certain safety hazards when the fresh air fan unit is in use. Summary of the invention

[0004] Based on this, when a traditional fresh air fan is in use, condensation is easily generated at the air outlet grille of the fresh air fan unit. When condensation is generated at the air outlet grille of the fresh air fan unit for a long time, it will have a certain impact on the indoor environment, and there are certain safety hazards when the fresh air fan unit is in use. An air outlet structure and fresh air equipment are proposed, which can reduce the formation of condensation when in use.

[0005] The specific technical solutions are as follows:

[0006] On the one hand, the present application relates to an air outlet structure, including an installation shell, an air guide member, an air outlet grille and an air equalizing member, the installation shell forming an installation cavity and an air outlet and a fresh air inlet connected to the installation cavity; the air guide member is provided with an air guide duct, the air inlet of the air guide duct is connected to the air outlet; the air outlet grille is arranged at the air outlet of the air guide duct, and the air guide member is used to converge the wind to the air outlet grille; the air equalizing member is arranged in the installation cavity, the air equalizing member forms an air equalizing duct, and the air outlet direction of the air equalizing duct is arranged at an angle to the air outlet direction of the air outlet grille.

[0007] When the above-mentioned air outlet structure is in use, the outside fresh air can enter the installation cavity along the fresh air inlet. The direction of the introduced fresh air is chaotic. The fresh air needs to pass through the air equalizer before being discharged. Since the air equalizer is provided with an air equalizer duct, the fresh air has the same wind direction along the air equalizer duct after passing through the air equalizer. Then the fresh air converges to the air outlet grille under the action of the air guide. At this time, the fresh air can surround the air outlet grille, so that the temperature at the air outlet grille is uniform and the surface temperature difference of each part of the air outlet grille is low. Furthermore, the air outlet direction of the air outlet grille is at an angle to the air outlet direction of the air equalizer duct. Therefore, the air discharged from the air outlet grille can be discharged at a certain angle. At this time, one side of the air outlet grille covered by the air discharged from the air outlet grille is not easy to produce condensation due to the low temperature change. The other side of the air outlet grille opposite to the one side has low heat transfer efficiency and is not easy to produce condensation due to no wind passing through.

[0008] The technical solution is further described below:

[0009] In one of the embodiments, the air outlet grille includes a mounting bracket and at least two grille plates, the grille plates are connected to the air guide member via the mounting bracket, and all the grille plates are spaced apart in the same direction, and the inclination direction of the grille plates is set at an angle to the air outlet direction of the air duct.

[0010] In one of the embodiments, the air guide duct is provided with an air guide section arranged at an angle to the air outlet direction of the air balance duct, and the air guide section is used to guide the wind discharged from the air balance duct in a direction converging to the air outlet grille.

[0011] In one of the embodiments, the air guide member includes two first air guide bodies and a second air guide body, the two first air guide bodies are arranged at intervals, there are two mounting brackets, one end of the grille plate is connected to one of the first air guide bodies through one of the mounting brackets, the other end of the grille plate is connected to the other first air guide body through the other mounting bracket, one end of the second air guide body is connected to one of the first air guide bodies, the other end of the second air guide body is connected to the other first air guide body, the two first air guide bodies and the second air guide body are surrounded to form the air guide duct, the air guide section includes a first air guide section and a second air guide section, the first air guide body is formed with the first air guide section, and the second air guide body is formed with the second air guide section;

[0012] The first wind guiding section is used to guide the wind from the end of the grille plate to the middle of the grille plate, and the second wind guiding section is used to guide the wind to one of the grille plates closest to the second wind guiding body.

[0013] In one of the embodiments, the grille plate is arranged to be inclined relative to the depth direction of the installation cavity, and the air outlet end of the grille plate is closer to the second air guide section than the air inlet end of the grille plate.

[0014] In one embodiment, the air outlet structure also includes a first side panel and a second side panel, the first side panel and the second side panel being arranged opposite to each other in the mounting shell, the first side panel and the first side panel being connected and a first heat insulating space being formed between the first side panel and the first side panel; the second side panel and the second side panel being connected and a second heat insulating space being formed between the second side panel and the second side panel.

[0015] In one of the embodiments, the air outlet structure further includes a first thermal insulation component and a second thermal insulation component, wherein the first thermal insulation component is disposed in the first thermal insulation space, and the second thermal insulation component is disposed in the second thermal insulation space.

[0016] In one embodiment, the air outlet structure also includes a layer plate assembly, and the installation shell also includes a third side surface corresponding to the front panel of the fresh air device, the layer plate assembly is connected to the third side surface, and the layer plate assembly forms a third insulation space.

[0017] In one of the embodiments, the air outlet structure further includes a cover plate assembly, wherein the cover plate assembly is connected to the third side surface, and along the vertical direction, the cover plate assembly is arranged below the layer plate assembly, and the cover plate assembly forms a fourth insulation space.

[0018] In one embodiment, the air equalizing element is a purification unit.

[0019] On the other hand, the present application also relates to a fresh air device, comprising an air outlet structure as described in any of the above items.

[0020] The above-mentioned fresh air device includes the air outlet structure in any of the above-mentioned embodiments. Therefore, when the fresh air device is in use, the outside fresh air can enter the installation cavity along the fresh air inlet. The direction of the introduced fresh air is chaotic. The fresh air needs to pass through the air equalizer before being discharged. Since the air equalizer is provided with an air equalizer duct, the fresh air has the same wind direction discharged along the air equalizer duct after passing through the air equalizer. Subsequently, the fresh air converges to the air outlet grille under the action of the air guide. At this time, the fresh air can surround the air outlet grille, so that the temperature at the air outlet grille is uniform and the surface temperature difference of each part of the air outlet grille is low. Furthermore, the air outlet direction of the air outlet grille is at an angle to the air outlet direction of the air equalizer duct. Therefore, the air discharged from the air outlet grille can be discharged at a certain angle. At this time, one side of the air outlet grille covered by the air discharged from the air outlet grille is not easy to produce condensation due to the low temperature change. The other side of the air outlet grille opposite to the one side has low heat transfer efficiency and is not easy to produce condensation due to no wind passing through.

[0037] When a traditional fresh air fan is in use, condensation water is easily generated on the surface of the fresh air fan unit. When the fresh air fan unit generates condensation water for a long time, it will have a certain impact on the indoor environment, and there are certain safety hazards when the fresh air fan unit is in use. Based on this, the present application proposes an air outlet structure 20 and a fresh air device 10, which can reduce the formation of condensation water when in use.

[0038] Please refer to Figure 1 The air outlet structure 20 in one embodiment includes an installation shell 100, which is formed with an installation cavity 110 and an exhaust port (not shown) and a fresh air inlet 120 connected to the installation cavity 110. The air outlet structure 20 also includes a fan (not shown), which can be arranged in the installation cavity 110. Under the action of the fan, the fresh air from the outside enters the installation cavity 110 along the fresh air inlet 120 and is discharged into the room along the exhaust port.

[0039] Please refer to Figure 2 and Figure 3 The fresh air inlet 120 may include a fresh air inlet 120 at the bottom and two fresh air inlets 120 at the left and right sides. The air outlet structure 20 also includes two covers 900. When one of the fresh air inlets 120 is opened, the cover 900 is used to seal the other two fresh air inlets 120. Specifically, the cover 900 is equipped with thermal insulation foam, and the cover 900 is sealed with the fresh air inlet 120 through the thermal insulation foam.

[0040] Please refer to Figure 2 and Figure 3 The mounting housing 100 includes a first side surface 130 and a second side surface 140 that are arranged opposite to each other, and the air outlet structure 20 also includes a first side plate 510 and a second side plate 520. For details, please refer to Figure 2 In the perspective of this figure, the first side surface 130 can be the left side surface, and the corresponding first side panel 510 can be the left side panel. The second side surface 140 can be the right side surface, and the corresponding second side surface 140 can be the right side panel. Please continue to refer to Figure 2 The first side plate 510 is connected to the first side surface 130, and a first heat insulation space (not shown) is formed between the first side plate 510 and the first side surface 130; the second side plate 520 is connected to the second side surface 140, and a second heat insulation space (not shown) is formed between the second side plate 520 and the second side surface 140. In this way, by providing the first heat insulation space and the second heat insulation space, the heat preservation performance of the air outlet structure 20 can be correspondingly improved, thereby reducing the formation of condensation water on the surface of the air outlet structure 20.

[0041] Specifically, the first side plate 510 and the first side surface 130 can be connected by means of a clamping connection or a screw connection; it should be noted that although the first side plate 510 and the first side surface 130 are connected, it does not prevent the other parts of the first side surface 130 from forming a first heat insulating space with other parts of the first side plate 510. Similarly, the second side plate 520 and the second side surface 140 can be connected by means of a clamping connection or a screw connection. It should be noted that although the second side plate 520 and the second side surface 140 are connected, it does not prevent the other parts of the second side surface 140 from forming a second heat insulating space with other parts of the second side plate 520.

[0042] For further information, please refer to Figure 2 In some embodiments, the air outlet structure 20 further includes a first heat-insulating member 610 and a second heat-insulating member 620. The first heat-insulating member 610 is disposed in the first heat-insulating space, and the second heat-insulating member 620 is disposed in the second heat-insulating space. In this way, the heat-insulating performance of the first heat-insulating space can be further improved by disposing the first heat-insulating member 610. The heat-insulating performance of the second heat-insulating space can also be further improved by disposing the second heat-insulating member 620.

[0043] Please refer to Figure 3 In some embodiments, the air outlet structure 20 further includes a layer plate assembly 700, and the mounting housing 100 further includes a third side surface 150 corresponding to the front panel 1000 of the fresh air device 10. Figure 3 In the perspective of this figure, the third side surface 150 can be the front side surface, and the front panel 1000 of the fresh air device 10 is correspondingly installed on the front side surface. The layer plate assembly 700 is connected to the third side surface 150, and the layer plate assembly 700 forms a third heat insulation space (not shown). In this way, the third heat insulation space can correspondingly improve the heat preservation performance of the air outlet structure 20, thereby reducing the formation of condensation water on the surface of the air outlet structure 20.

[0044] Specifically, in some embodiments, the layer panel assembly 700 can be a split structure, including a first layer panel 710 and a second layer panel 720, and the first layer panel 710 and the second layer panel 720 are connected by corresponding connection methods, such as snap connection or screw connection; a third insulation space is formed between the first layer panel 710 and the second layer panel 720.

[0045] In some other embodiments, the layer plate assembly 700 may be an integral structure, and a third heat-insulating space is formed inside the layer plate assembly 700. In this case, the layer plate assembly 700 may be a solid structure or an internally hollow structure.

[0046] Please refer to Figure 3In some embodiments, the air outlet structure 20 further includes a cover plate assembly 800, which is connected to the third side surface 150. In the vertical direction F, the cover plate assembly 800 is disposed below the layer plate assembly 700, and the cover plate assembly 800 forms a fourth heat insulation space (not shown). In this way, the fourth heat insulation space can correspondingly improve the heat preservation performance of the air outlet structure 20, thereby reducing the formation of condensation water on the surface of the air outlet structure 20. Please refer to Figure 3 ,exist Figure 3 From a perspective of FIG. 1 , the cover assembly 800 may be disposed in a bottom area of ​​the mounting shell 100 .

[0047] Specifically, in some embodiments, the cover plate assembly 800 can be a split structure, including a first cover plate (not shown) and a second cover plate (not shown), and the first cover plate and the second cover plate are connected by corresponding connection methods, such as snap connection or screw connection; a fourth insulation space is formed between the first cover plate and the second cover plate.

[0048] In some other embodiments, the cover plate assembly 800 may be an integral structure, and a fourth heat-insulating space is formed inside the cover plate assembly 800. In this case, the cover plate assembly 800 may be a solid structure or an internally hollow structure.

[0049] In the above embodiments, the gap insulation principle is adopted and corresponding insulation space is set to prevent condensation from forming on the surface of the air outlet structure 20. However, in actual applications, condensation is also easily formed at the air outlet of the air outlet structure 20. Based on this, it is necessary to solve the problem of condensation near the air outlet of the air outlet structure 20.

[0050] Please refer to Figures 4 to 6 In some embodiments, the air outlet structure 20 further includes an air guide member 200, an air outlet grille 300 and an air equalizing member 400. The air guide member 200 is provided with an air guide duct 202, and the air inlet of the air guide duct 202 is connected to the air outlet. The air outlet grille 300 is arranged at the air outlet of the air guide duct 202, and the air guide member 200 is used to converge the wind to the air outlet grille 300. The air equalizing member 400 is arranged in the installation cavity 110, and the air equalizing member 400 forms at least two air equalizing ducts 402 with the same air outlet direction, and the air outlet direction of the air equalizing duct 402 is arranged at an angle to the air outlet direction of the air outlet grille 300. Among them, the air outlet direction of the air outlet grille 300 is as follows: Figure 6 In the F1 direction, the air outlet direction of the air duct 402 is as follows Figure 6 F2 direction in

[0051] When the above-mentioned air outlet structure 20 is in use, the outside fresh air can enter the installation cavity 110 along the fresh air inlet 120. The direction of the introduced fresh air is chaotic. The fresh air needs to pass through the air equalizing member 400 before being discharged. Since the air equalizing member 400 is provided with at least two air equalizing ducts 402 with the same air outlet direction, the fresh air has the same wind direction when discharged along the air equalizing duct 402 after passing through the air equalizing member 400. Subsequently, the fresh air converges toward the air outlet grille 300 under the action of the air guide member 200. At this time, the fresh air can surround the air outlet grille 300, so that the temperature at the air outlet grille 300 is uniform and the temperature difference of each surface of the air outlet grille 300 is low. Furthermore, the air outlet direction of the air outlet grille 300 is at an angle to the air outlet direction of the air balancing duct 402. Therefore, the wind discharged from the air outlet grille 300 can be discharged at a certain angle. At this time, one side of the air outlet grille 300 covered by the wind discharged from the air outlet grille 300 is not easy to produce condensation due to the lower temperature change. The other side of the air outlet grille 300 opposite to the one side has a lower heat transfer efficiency and is not easy to produce condensation due to no wind passing through.

[0052] Please refer to Figure 5 and Figure 6 In some embodiments, the air distribution unit 400 may be a purification unit. In this way, when the introduced fresh air passes through the purification unit, the purification unit can purify the fresh air and improve the cleanliness of the fresh air. At the same time, the purification unit can also adjust the delivery direction of the fresh air under the action of the air distribution duct 402, so that the fresh air is discharged in the same direction. For example, please refer to Figure 6 From the perspective of this figure, the air outlet direction of each air duct 402 in the purification unit is the same as the depth direction F of the installation cavity 110, that is, the vertical direction.

[0053] Please refer to Figure 7 , Figure 7 Optional structures of each air outlet grille 300 are shown. In this embodiment, the air outlet grille 300 includes a mounting bracket 310 and at least two grille plates 320, the grille plates 320 are connected to the air guide 200 through the mounting bracket 310, and all the grille plates 320 are arranged at intervals along the same direction, for example, the grille plates 320 can be arranged at intervals along the length direction of the mounting bracket 310, and the length direction of the mounting bracket 310 is shown in FIG. L.

[0054] Please continue to refer to Figure 6 The inclination direction of the grille plate 320 is set at an angle to the air outlet direction of the air duct 402. The installation position of the grille plate 320 determines the air outlet direction of the air outlet grille 300. When the grille plate 320 is set at an angle to the air outlet direction of the air duct 402, the air outlet direction of the air outlet grille 300 is also set at an angle to the air outlet direction of the air duct 402.

[0055] In some embodiments, the air guide duct 202 is provided with an air guide section arranged at an angle to the air outlet direction of the air balancing duct 402 , and the air guide section is used to guide the air discharged from the air balancing duct 402 in a direction converging to the air outlet grille 300 .

[0056] For details, please refer to Figure 5 and Figure 6 The air guide 200 includes two first air guide bodies 210 and a second air guide body 220, the two first air guide bodies 210 are arranged at intervals, there are two mounting brackets 310, one end of the grille plate 320 is connected to one of the first air guide bodies 210 through one of the mounting brackets 310, the other end of the grille plate 320 is connected to the other first air guide body 210 through another mounting bracket 310, one end of the second air guide body 220 is connected to one of the first air guide bodies 210, and the other end of the second air guide body 220 is connected to the other first air guide body 210. The wind body 210 is connected, and the two first wind guide bodies 210 and the second wind guide bodies 220 are surrounded to form an air guide duct 202. The air guide section includes a first air guide section 212 and a second air guide section 222. The first air guide body 210 is formed with a first air guide section 212, and the second air guide body 220 is formed with a second air guide section 222; the first air guide section 212 is used to guide the wind along the end of the grille plate 320 to the middle of the grille plate 320, and the second air guide section 222 is used to guide the wind to the one of the grille plates 320 closest to the second air guide body 220.

[0057] Please refer to Figure 5 and Figure 6 The first air guide section 212 and the second air guide section 222 are both inclined relative to the vertical direction F, wherein the vertical direction F may also be the depth direction F of the installation cavity 110, and the air outlet end of the first air guide section 212 is closer to the grille plate 320 than the air inlet end of the first air guide section 212. The air outlet end of the second air guide section 222 is closer to the grille plate 320 than the air inlet end of the second air guide section 222.

[0058] Furthermore, grille transition areas 302 are left at both ends of the grille plate 320, wherein the grille transition area 302 is generally used to connect with the mounting bracket 310. The grille transition area 302 is windproof. In order to avoid condensation in the grille transition area 302 due to uneven temperature, the first air guide section 212 is set to be inclined relative to the depth direction F of the mounting cavity 110, and when the air outlet end of the first air guide section 212 is closer to the grille plate 320 than the air inlet end of the first air guide section 212, the airflow shrinks toward the middle of the central air outlet grille 300, so that the alternation of hot and cold in the grille transition area 302 is reduced, and condensation is not easy to generate.

[0059] Please refer to Figure 6In some embodiments, the grille plate 320 is tilted relative to the depth direction F of the installation cavity 110, and the air outlet end of the grille plate 320 is closer to the second air guide section 222 than the air inlet end of the grille plate 320. Considering that when the fresh air unit is a wall-mounted fresh air unit, the airflow is fan-shaped, when the grille plate 320 is tilted relative to the depth direction F of the installation cavity 110, it can prevent the fresh air from blowing onto the wall, causing the wall to turn yellow or black.

[0060] For details, please refer to Figure 5 and Figure 6 In some embodiments, the complementary angle of the angle formed between the grille plate 320 and the depth direction F of the installation cavity 110 is M, the complementary angle of the angle formed between the first air guide section 212 and the depth direction F of the installation cavity 110 is E, and the complementary angle of the angle formed between the second air guide section 222 and the depth direction F of the installation cavity 110 is P. Preferably, E is 33°-35°. P is 70°-80°.

[0061] For example, in one embodiment, the M angle is set to 75 degrees, and the wind equalizing member 400 is a high-efficiency filter. Under the action of the resistance of the high-efficiency filter, the fresh air is changed from a disturbed airflow to a parallel flow airflow after passing through the high-efficiency filter. At this time, the grille plate 320 is inclined 25° relative to the depth direction of the installation cavity 110. The P angle is set to 36 degrees. The airflow passes through the second air guide section 222, which will generate a force along the second air guide section 222. At the same time, the airflow passes through the high-efficiency filter and there is a vertical upward force. Under the action of the combined force, the airflow will generate a parabolic acceleration, and the airflow will quickly pass through the grille plate 320. The setting of the P angle and the M angle in this way makes the airflow passing through the guide surface of the grille plate 320 close to the second air guide section 222 form a projectile airflow, and the grille plate 320 is not easy to condense.

[0062] In addition, some embodiments also relate to a fresh air device 10, including an air outlet structure 20 in any of the aforementioned items.

[0063] The above-mentioned fresh air device 10 includes the air outlet structure 20 in any of the above-mentioned embodiments. Therefore, when the fresh air device 10 is in use, the outside fresh air can enter the installation cavity 110 along the fresh air inlet 120. The direction of the introduced fresh air is chaotic. The fresh air needs to pass through the air equalizer 400 before being discharged. Since the air equalizer 400 is provided with at least two air equalizer ducts 402 with the same air outlet direction, the fresh air is discharged in the same direction along the air equalizer duct 402 after passing through the air equalizer 400. Subsequently, the fresh air converges toward the air outlet grille 300 under the action of the air guide 200. At this time, the fresh air can surround the air outlet grille 300, so that the temperature at the air outlet grille 300 is uniform. The temperature difference of each surface of the air outlet grille 300 is low. Furthermore, the air outlet direction of the air outlet grille 300 is at an angle to the air outlet direction of the air equalizer duct 402. Therefore, the air discharged from the air outlet grille 300 can be discharged at a certain angle, so condensation is not easy to occur at the air outlet grille 300.
