Description

Technical Field

[0001] This invention relates to the field of equipment technology for integrated ceiling systems, specifically to a linear air outlet device and an air handling device. Background Technology

[0002] Most existing air handling devices use Figure 1 The structure shown depicts an airflow that enters the fan housing 1 through the air inlet 2, passes through a fan (and may then pass through a filter, heating, or cooling device, depending on the application), enters the air outlet 4, and then flows into the room through the air outlets 3 arranged linearly along the length of the air outlet 4. However, in existing linear air outlet devices, the length direction is the same as the direction of the fan outlet. Because the air accelerated and blown out by the fan is subject to inertial force, it easily accumulates at the end of the air outlet 4 (i.e.,...). Figure 1 The air is discharged near the left-middle section of the outlet, and the front section (i.e., the middle left) is the exhaust outlet. Figure 1 The airflow on the right side is relatively weak, resulting in uneven airflow. Summary of the Invention

[0003] Therefore, the technical problem to be solved by the present invention is to overcome the defect of the existing linear air outlet device where the air volume is concentrated at the end of the air outlet due to the inertial force of the airflow, thereby providing a linear air outlet device and a corresponding air handling device with a relatively more uniform air volume.

[0004] To solve the above-mentioned technical problems, the technical solution adopted in this application is as follows:

[0005] A linear air outlet device, comprising:

[0006] The bellows has a bellows inlet and an air outlet. The air outlet is set along the length of the bellows. The bellows inlet is suitable for connecting with the outlet of an external fan. The orientation of the bellows inlet is perpendicular to the orientation of the air outlet.

[0007] A primary airflow guide is installed on the outlet side of the air box inlet; the airflow flowing in from the air box inlet is guided by the primary airflow guide to flow towards the end of the air box;

[0008] The secondary air guide is installed inside the air box. The air inlet of the secondary air guide faces the air outlet of the primary air guide, and the air outlet of the secondary air guide faces the air outlet.

[0009] Optionally, in the direction pointed to by the air outlet end of the primary guide, the secondary guide divides the width of the air outlet end of the primary guide into equal intervals; along the length of the air box, the air outlet end of the secondary guide divides the distance between the air box inlet and the side wall of the air box into equal intervals.

[0010] Optionally, the bellows inlet is located in the middle region of the bellows along its length. The primary guide includes a first guide and a second guide. The first guide directs a portion of the airflow flowing in from the bellows inlet toward one end of the bellows along its length, and the second guide directs a portion of the airflow flowing in from the bellows inlet toward the other end of the bellows along its length.

[0011] Optionally, two or more secondary guides are provided downwind of both the first and second guides; the length of the secondary guides gradually increases along the air outlet direction of the primary guide.

[0012] Optionally, the secondary guide includes a transition plate and an outlet plate connected together. In the direction pointed to by the air outlet end of the primary guide, the transition plate divides the width of the air outlet end of the primary guide equally at intervals; along the length direction of the air box, the outlet plate divides the distance between the air box inlet and the side wall of the air box equally at intervals.

[0013] Optionally, from the perspective of the main viewing direction, the bellows is rectangular, the edge of the bellows inlet abuts against the side of the bellows away from the air outlet, a transition angle is provided between the side of the bellows away from the air outlet and the end side of the bellows, and the first guide member and the second guide member abut against each other.

[0014] Optionally, a third guide is provided on the side of the bellows inlet near the air outlet, and the airflow flowing in from the bellows inlet is guided by the third guide to flow toward the air outlet; the third guide abuts against the first guide and the second guide.

[0015] An air handling device, comprising:

[0016] The fan is equipped with a treatment function device at the inlet and / or outlet;

[0017] In the aforementioned linear air outlet device, the outlet of the fan is connected to the inlet of the air box.

[0018] Optionally, a fan box is provided to enclose the fan, and the fan box is connected to two air intake chambers, each with an air inlet; the two air intake chambers are located on both sides of the linear air outlet device.

[0019] Optionally, the fan includes a volute and a rotor disposed within the volute and driven by a drive device; the volute is a spirally involute, the rotor is a double-sided air intake rotor, and the drive device is located on one side of the rotor.

[0020] Optionally, from the perspective of the main viewing direction, the bellows inlet is rectangular. The connecting line between the first guide and the second guide abutting back to back divides the width of the bellows inlet into two segments, L1 and L2. The distances between the bellows inlet and the side walls at both ends of the bellows are L3 and L4, with L3 close to L1 and L4 close to L2. L2 is located on the outer side of the spiral involute shape of the volute relative to L1.

[0021] The relationships between L1, L2, L3, and L4 are one of the following two:

[0022] One possibility is that L1 = L2, and L3 / L4 = 0.6 to 0.8;

[0023] Another option is L3 = L4, L1 / L2 = 1.1 to 1.3.

[0024] Optionally, from the perspective of the main viewing direction, the distance between the bellows inlet and the side walls at both ends of the bellows is L3 and L4. The connecting line between the third guide and the first and second guides divides the height of the bellows inlet into two segments, h1 and h2. The width of the third guide is the same as that of the bellows inlet and is L5.

[0025] Depending on the position of the side of the wind turbine equipped with the drive device relative to h1 and h2, it has one of the following two structures:

[0026] One option is that the side of the wind turbine equipped with the drive device is closer to h1, then h1 / h2 = (1.1~1.5)L5 / (L3+L4);

[0027] Another option is that the side of the wind turbine with the drive device is closer to h2, then h1 / h2 = (0.8~0.9)L5 / (L3+L4).

[0028] By adopting the above technical solution, the present invention has the following technical effects:

[0029] 1. The linear air outlet device provided by this invention avoids the large air volume deviation caused by the accumulation effect at the primary air outlet by making the orientation of the air box inlet perpendicular to the orientation of the air outlet and by having the secondary guide component cut off the air outlet from the primary guide component. Furthermore, it ensures that the airflow from the secondary guide component exits from the middle section of the air box, solving the problem of air volume concentration at the end of the air outlet caused by the inertial force of the airflow in existing equipment. Since the orientation of the air box inlet is perpendicular to the orientation of the air outlet, the upstream components do not need to be extended further along the length of the air box, which helps to shorten the overall length of the equipment and make its structure more compact.

[0030] 2. The linear air outlet device provided by the present invention makes the secondary guide element equally spaced along the width direction of the primary guide element, and the secondary guide element is evenly distributed along the length direction of the air box, so that the airflow is equally divided and sent out, thereby improving the uniformity of air outlet.

[0031] 3. The linear air outlet device provided by the present invention, by placing the air box inlet in the middle region of the air box in the length direction, greatly shortens the distance from the air box inlet to the farthest air outlet. On the one hand, it can reduce the kinetic energy loss of airflow in the excessively long channel. On the other hand, if the device is used in heating or cooling equipment, the shorter air outlet stroke can reduce the loss of heat or cold, making the air temperature more uniform.

[0032] 4. The linear air outlet device provided by the present invention has two or more secondary air outlets at the downwind end of both the first air outlet and the second air outlet, which can blow out the air in a more refined manner.

[0033] 5. The linear air outlet device provided by the present invention shortens the total length of the secondary air guide by setting a secondary air guide with a transition plate and an outlet plate, thereby reducing the noise generated by the friction between the air guide and the airflow.

[0034] 6. The linear air outlet device provided by the present invention, by having the first and second guide members arranged opposite to each other, makes the outgoing airflow on the same straight line, and the wind box is rectangular and has a transition angle, so that the wind box also constitutes a guide member, which improves the uniformity of air volume at both ends of the wind box and makes the device structure compact.

[0035] 7. The linear air outlet device provided by the present invention, by setting a third guide member, allows the airflow at the inlet of the air box to be directly guided to the aforementioned contact area, supplementing the airflow between the first guide member and the second guide member, and improving the uniformity of the airflow in the overall area of ​​the air outlet.

[0036] 8. The air handling device provided by the present invention, because it is equipped with the linear air outlet device provided by the present invention, not only has the advantages of the linear air outlet device, but also can make full use of the width of the air box. After being combined with other components of roughly the same width, the structure of the entire device is very compact and the overall space occupied is small.

[0037] 9. The air handling device provided by the present invention adopts a dual-channel air intake structure on both sides of the air outlet 3. When the air outlet is long enough and the air output is uniform, it does not cause short-circuit problems between air intake and output, but can absorb indoor air more extensively, forming an effective replacement of old and new air, and making the structure of the entire device more compact.

[0038] 10. The air handling device provided by the present invention adopts a double-sided air intake impeller 8, which has the characteristics of small size and large air volume, thereby improving the air delivery capacity of the whole machine.

[0039] 11. The air handling device provided by the present invention determines the corresponding structural relationship according to the placement position of the spiral involute-shaped volute, further improving the uniformity of the air output of the whole machine.

[0040] 12. The air handling device provided by the present invention determines the corresponding structural relationship according to the position of the side of the impeller with the motor relative to the position of the impeller, thereby further improving the uniformity of the air output of the whole machine.

Therefore, they should not be construed as limitations on this invention.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0053] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0054] Example 1

[0055] This embodiment provides a linear air outlet device.

[0056] In one implementation, such as Figure 4 and 6As shown, it includes a bellows 20, a primary air guide 21, and a secondary air guide 17. The air guide, as referred to here, is a component that guides and deflects the airflow; it is generally a plate-like part, but can also be in the form of a block or tube. The bellows 20 has a bellows inlet 9 and an outlet 3, with the outlet 3 arranged along the length of the bellows 20. The orientation of the bellows inlet 9 is perpendicular to the orientation of the outlet 3; in other words, the airflow blowing in from the bellows inlet 9 is perpendicular to the airflow blowing out from the outlet 3. However, for ease of use, most air outlet devices usually have a vane mechanism at the outlet 3 to adjust the airflow direction. The airflow blowing out from the outlet 3 refers to the airflow that is not deflected by the vane mechanism. The primary air guide 21 is located on the outlet side of the bellows inlet 9; the airflow flowing in from the bellows inlet 9 is guided by the primary air guide 21 to flow towards the end of the bellows 20. It should be noted that the end of the bellows 20 mentioned here does not specifically refer to both ends of the bellows 20; only one end is acceptable. The secondary guide 17 is disposed inside the air box 20. The air inlet of the secondary guide 17 faces the air outlet of the primary guide 21, and the air outlet of the secondary guide 17 faces the air outlet 3.

[0057] In the device described above, airflow is blown in from the bellows inlet 9, guided by the primary guide 21 to the secondary guide 17, and then blown out by the secondary guide 17 to the outlet 3. Due to inertial force (also known as centrifugal force), the airflow tends to accumulate more easily on the outer side of the guide's deflection path as it passes through the guide. However, in this embodiment, although the airflow also experiences the aforementioned accumulation effect after passing through the primary guide 21, resulting in unevenness in its rotational radial direction, it is distributed more evenly in the width direction of the primary guide 21. Subsequently, the airflow is intercepted and separated by the secondary guide 17 at the leeward end, thus splitting into at least two airflow streams (depending on the number of secondary guides 17). The segmented airflow is then blown out from the middle section (i.e., not the end) of the bellows 20 along its length by the secondary guide 17, thus ensuring a more balanced airflow from the linearly arranged outlets 3, unlike in existing technologies where airflow tends to concentrate at the end of the outlets 3. This solves the problem of uneven airflow caused by the inertial force of airflow in existing equipment. Furthermore, because the bellows inlet 9 is perpendicular to the outlet 3, upstream components do not need to be extended further along the length of the bellows 20, which helps to shorten the overall length of the equipment and make its structure more compact.

[0058] Based on the above embodiments, in a preferred embodiment, in the direction pointed to by the air outlet end of the primary guide member 21 (i.e., the flow direction of the airflow blown out from the primary guide member 21), the secondary guide member 17 equally divides the width of the air outlet end of the primary guide member 21. In other words, the secondary guide member 17 equally divides the airflow blown out from the primary guide member 21. This division is achieved by equally dividing the width of the air outlet end of the primary guide member 21 along the airflow path. Because the divided airflow is evenly cut in the width direction of the primary guide member 21, the air volume between each airflow is approximately equal, and there will be no large deviation due to the accumulation effect at the primary guide member 21. Furthermore, along the length direction of the bellows 20, the air outlet end of the secondary guide member 17 equally divides the distance between the bellows inlet 9 and the end side wall of the bellows 20 (i.e., the wall panel at one end in the length direction), thus equalizing the aforementioned evenly divided airflow and blowing it out along the length direction of the bellows 20. Through the above two equidistant divisions, the air outlet is refined into multiple uniform airflows, making the air outlet 3 more uniform and detailed in the overall section.

[0059] Based on the above embodiments, in a preferred embodiment, such as Figure 4 and 6 As shown, the bellows inlet 9 is located in the middle region of the bellows 20 along its length (it should be noted that the middle region here refers to a region outside the two ends, not specifically the center of the bellows 20 along its length). The primary guide member 21 includes a first guide member 16 and a second guide member 14. The first guide member 16 directs a portion of the airflow flowing in from the bellows inlet 9 toward one end of the bellows 20 along its length (to... Figure 6 (i.e., the left end), the second guide 14 directs part of the airflow flowing in from the bellows inlet 9 toward the other end of the bellows 20 along its length (to... Figure 6 (i.e., the right end). It should be noted that the airflow guidance towards the end of the bellows 20 mentioned here does not specifically refer to a direction that is completely in line with the length of the bellows 20; it is acceptable as long as it produces an effect that causes the airflow to deflect towards the end of the bellows 20.

[0060] This configuration significantly shortens the distance from the bellows inlet 9 to the furthest outlet 3. On one hand, it reduces kinetic energy loss in the excessively long channel; on the other hand, if this device is used in heating or cooling equipment, the shorter outlet path reduces heat or cold loss, resulting in a more even outlet air temperature. For example... Figure 1 If the existing equipment is a heater, its linear outlet is usually set to be relatively long in order to increase the air outlet coverage area. This leads to a significant increase in heat loss during the transport process due to the excessively long air outlet path of the heated gas, resulting in… Figure 1The air temperature is uneven, with the left side having a lower outlet temperature and the right side having a higher outlet temperature. This device can solve this problem of uneven air temperature.

[0061] Based on the above embodiments, in a preferred embodiment, such as Figure 4 and 6 As shown, two or more secondary guides 17 are provided downwind of both the first guide 16 and the second guide 14. This arrangement is to more evenly divide the flow.

[0062] Based on the above embodiments, in a preferred embodiment, such as Figure 4 and 6 As shown, the secondary guide member 17 includes a connected transition plate 12 and an outlet plate 13, with the head end of the transition plate 12 serving as the air inlet end of the secondary guide member 17. In the direction indicated by the air outlet end of the primary guide member 21, the transition plate 12 equally divides the width of the air outlet end of the primary guide member 21. Along the length of the air box 20, the outlet plate 13 equally divides the distance between the air box inlet 9 and the end sidewall of the air box 20. Along the air outlet direction of the primary guide member 21, the length of the secondary guide member 17 gradually increases.

[0063] In this embodiment, the second guide member 14 does not have a straight inlet plate at the air inlet end; instead, it relies directly on the transition plate 12, which deflects the airflow direction, to divide the airflow. This is because airflow generates noise when flowing through the guide member, and the longer the guide member, the greater the noise. Since the bellows 20 is relatively long in length compared to other dimensions, setting an inlet plate at the air inlet end of the second guide member 14 would easily result in an excessively long guide member, significantly increasing the overall length of the guide member and exacerbating the noise problem. Furthermore, the airflow blown out by the primary guide member 21 does not require much guidance to achieve its predetermined path under inertial force, thus saving material by not setting an inlet plate. The outlet plate 13 at the air outlet end of the second guide member 14 prevents airflow away from the transition plate 12 from being deflected due to inertial force during the guidance process, ensuring that the outflowing airflow follows the predetermined path and maintaining a balanced airflow at each outlet 3.

[0064] Based on the above embodiments, in a preferred embodiment, from the perspective of the main viewing direction (i.e.) Figure 6 From a certain perspective, the bellows 20 is rectangular. The edge of the bellows inlet 9 abuts against the side of the bellows 20 away from the air outlet 3. A transition angle 18 is provided between the side of the bellows 20 away from the air outlet 3 and the end side of the bellows 20. The first guide member 16 and the second guide member 14 abut against each other, that is, their outlet directions are two opposite directions on a line, and they abut against each other, so as to divide all the airflow and make it flow in two directions.

[0065] Because the first guide member 16 and the second guide member 14 are arranged opposite to each other, the outgoing airflow is on the same straight line. Since the bellows 20 is rectangular, the edge of the bellows 20 near the bellows inlet 9 also functions as a straight-plate guide member. Therefore, a transition angle 18 is provided at the corner where this side meets the end side of the bellows, making the bellows 20 also a guide member, further improving the uniformity of airflow, especially at both ends of the bellows. Furthermore, the width of the bellows 20 (i.e.,...) Figure 6 The height (from the perspective of view) has been greatly reduced, and the structure of the entire device has become very compact.

[0066] Based on the above embodiments, in a preferred embodiment, such as Figure 4 and 6 As shown, a third guide 15 is provided on the side of the air box inlet 9 near the air outlet 3. The airflow flowing in from the air box inlet 9 is guided by the third guide 15 to flow toward the air outlet 3. The third guide 15 abuts against the first guide 16 and the second guide 14.

[0067] If only the first guide 16 and the second guide 14 facing the end of the air box 20 are provided, the air volume in the area of ​​the air outlet 3 corresponding to the point where the two meet will be low. However, the third guide 15 provided above can directly guide the airflow of the air box inlet 9 to the aforementioned meeting area, thus improving the uniformity of the air volume of the entire area of ​​the air outlet 3.

[0068] Example 2

[0069] This embodiment provides an air handling device.

[0070] In one implementation, such as Figures 2 to 6 As shown, it includes: a fan 7 and the linear air outlet device of Embodiment 1. The outlet of the fan 7 is connected to the inlet 9 of the air box. The fan 7 is provided with a processing function device 19 at the inlet and / or outlet. The processing function device 19 mentioned here refers to a device such as an air filter, humidifier, heater, or cooler that performs air processing, and can be configured with corresponding functional components for different usage scenarios.

[0071] This air handling unit not only has the advantages of uniform airflow and reduced heat / cold loss during cooling / heating operations, but also, because the orientation of the air box inlet 9 is perpendicular to the orientation of the air outlet 3, it does not need to be like... Figure 1 The existing equipment is too long overall, and this design of the bellows inlet and outlet can make full use of the width of the bellows 20 (i.e., Figure 6 The height (from the perspective) can be combined with other components of roughly the same width to make the entire device very compact and occupy less space.

[0072] Based on the above embodiments, in a preferred embodiment, such as Figures 1 to 3 As shown, a fan housing 1 encloses the fan 7. The fan housing 1 is connected to two air intake chambers 5 via a connecting pipe 6. Each air intake chamber 5 has an air inlet 2. The air inlet can be designed as a grille air intake, a slotted air intake, or other air intake forms as needed. The two air intake chambers 5 are located on both sides of the linear air outlet device.

[0073] This dual-channel air intake structure on both sides of the air outlet 3 does not cause short-circuit problems between air intake and supply when the air outlet 3 is long enough and the air supply is uniform. However, it can absorb indoor air more extensively, forming an effective replacement of old and new air, and making the structure of the whole device more compact.

[0074] Based on the above embodiments, in a preferred embodiment, such as Figures 3 to 5 As shown, the fan 7 includes a volute and a rotor 8 disposed within the volute and driven by a drive device. The volute is a spirally involute, and the rotor 8 is a double-sided air intake rotor. The drive device is located on one side of the rotor 8. Specifically, in this embodiment, the drive device is a motor 10. The bottom of the motor 10 is connected to the side wall of the fan housing 1 via a motor bracket 11. This structure ensures that both rotors 8 have gaps with the side wall of the fan housing 1, allowing the rotor 8 to complete double-sided air intake. The double-sided air intake rotor 8 has the characteristics of small size and large air volume, improving the overall air delivery capacity of the unit.

[0075] Based on the above embodiments, in a preferred embodiment, in Figure 6 From the perspective of the main viewing direction, the bellows inlet 9 is rectangular. The connecting line between the first guide member 16 and the second guide member 14, which abut against each other, divides the width of the bellows inlet 9 into two segments, L1 and L2. The distances between the bellows inlet 9 and the two side walls of the bellows 20 are L3 and L4, with L3 closer to L1 and L4 closer to L2. L2 is located on the outer side of the spiral involute shape of the volute relative to L1. L1, L2, L3, and L4 have one of the following two relationships: one is L1 = L2, L3 / L4 = 0.6 to 0.8; the other is L3 = L4, L1 / L2 = 1.1 to 1.3.

[0076] Due to the influence of the spirally opening volute structure, the airflow at the volute outlet tends to concentrate on the outer side of the volute under the action of centrifugal force. In this embodiment, L2 is located on the outer side of the spirally opening volute relative to L1, so the airflow on the L2 side will be greater than that on the L1 side. If the linear air outlet device adopts a completely symmetrical structural design, there will still be a certain degree of uneven airflow. Therefore, this embodiment adopts two solutions: one is to set L1 = L2, that is, the first guide element 16 and the second guide element 14 are symmetrical, which should satisfy L3 / L4 = 0.6~0.8; the other is to set L3 = L4, which can be regarded as symmetrically arranging the shell of the wind box 20 and the guide elements inside, in which case L1 / L2 = 1.1~1.3 should be satisfied. This way, the overall airflow of the device can achieve a better uniform effect. Symmetrical arrangement of related components facilitates product design, manufacturing, and assembly, and is also more aesthetically pleasing.

[0077] Based on the aforementioned implementation methods, in another preferred implementation method, in Figure 6 From the perspective of the main viewing direction, the distances between the bellows inlet 9 and the two side walls of the bellows 20 are L3 and L4. The connecting line between the third guide member 15 and the first guide member 16 and the second guide member 14 divides the height of the bellows inlet 9 into two segments, h1 and h2. The width of the third guide member 15 is the same as that of the bellows inlet 9, which is L5. Depending on the position of the side of the impeller 8 with the motor 10 relative to h1 and h2, it has one of the following two structures: one is that the side of the impeller 8 with the motor 10 is closer to h1, then h1 / h2 = (1.1~1.5)L5 / (L3+L4); the other is that the side of the impeller 8 with the motor 10 is closer to h2, then h1 / h2 = (0.8~0.9)L5 / (L3+L4).

[0078] Because the air intake channel on the motor side of the wind turbine 8 is obstructed by the motor 10, its air intake volume is less than that on the other side of the open structure of the wind turbine 8. This ultimately results in uneven airflow in the wind turbine 7 along the axial direction of the wind turbine 8. Figure 6 The airflow is uneven between the h1 and h2 sides. To overcome this problem, this embodiment requires that the motor side of the impeller 8 be located on the h1 and h2 sides respectively, and the above two different structural relationships be satisfied accordingly, so that the three consecutive segments L3, L5, and L4 of the air outlet 3 can achieve a generally uniform airflow.

[0079] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
