Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and more particularly to the field of humidification technology for aircraft. Background Technology

[0002] In response to passengers' demand for a high humidity environment in the cabin, the previous method of whole-cabin humidification was used. This involved injecting water vapor into the air that was about to be delivered into the cabin through an air distribution manifold, thereby increasing the humidity of the cabin space to a certain desired level.

[0003] The humidification method described above targets the entire cabin environment, including the area where passengers are located and other equipment and structures. Therefore, while high humidity can meet the humidity requirements of the area where passengers are located, it may cause corrosion to other equipment and structures.

[0004] Therefore, there is an urgent need for a local humidification vent and method that can humidify only the area where passengers are located, avoiding humidification of equipment and structures in other areas. Summary of the Invention

[0005] This invention is made to solve the above-mentioned technical problems. Its purpose is to provide a local humidification air outlet and a local humidification method that can integrate ventilation and humidification functions to locally humidify the target microenvironment.

[0006] One aspect of the present invention provides a local humidification air outlet, comprising a mounting housing for installation on a device body, wherein the outlet includes: an outer humidification pipe assembly, which is attached to the mounting housing and installed thereon, and is used to deliver humidified air with a predetermined humidity to a target microenvironment; and an inner ventilation pipe assembly, which is nested within the outer humidification pipe assembly and is used to deliver air with a humidity lower than the predetermined humidity to the target microenvironment.

[0007] According to the above structure, by nesting the external humidification pipe assembly for delivering humid air with a predetermined humidity to the target microenvironment with the inner ventilation pipe assembly for delivering air with a lower humidity than the predetermined humidity to the target microenvironment, ventilation and humidification functions can be integrated into one structure. Compared with the prior art where the humidification pipe assembly is set separately outside the ventilation structure, the structure is simpler and the installation space is smaller.

[0008] Furthermore, as described above, both the outer humidification pipe assembly and the inner ventilation pipe assembly target the specific microenvironment. Therefore, they can replace the existing method of humidifying the entire cabin environment, allowing for localized humidification of the target microenvironment. For example, they can locally humidify only the area where passengers are located, avoiding humidification of areas containing equipment and structures, thereby preventing corrosion in those areas.

[0009] The local humidification air outlet of the second aspect of the present invention is based on the local humidification air outlet of the first aspect of the present invention, wherein an outer humidification flow channel is formed between the inner surface of the outer humidification pipe assembly and the outer surface of the inner ventilation pipe assembly, and the outer humidification flow channel is used for the circulation of the humidified air.

[0010] According to the above structure, since the outer humidification channel for supplying humidified air is formed by the inner surface of the outer humidification pipe assembly and the outer surface of the inner ventilation pipe assembly, in other words, the outer surface of the inner ventilation pipe assembly is shared as part of the outer humidification channel. Therefore, compared with the existing technology of setting up a separate pipe structure to form the outer humidification channel, the structure is simple, requires less installation space, and can save installation space.

[0011] The local humidification air outlet of the third aspect of the present invention is based on the local humidification air outlet of the second aspect of the present invention, wherein the inner ventilation pipe assembly is capable of reciprocating relative to the outer humidification pipe assembly. The inner ventilation duct assembly has an inner limiting plate protruding from it, and the outer humidification duct assembly has an outer limiting groove recessed therein. The inner limiting plate is embedded in the outer limiting groove in a reciprocating manner.

[0012] According to the above structure, by setting the protruding inner limiting plate and the recessed outer limiting groove so that the inner limiting plate is embedded in the outer limiting groove in a reciprocating manner, the inner ventilation duct assembly can be limited to reciprocating movement within a certain range through a simple limiting structure.

[0013] The local humidification air outlet of the fourth aspect of the present invention is based on the local humidification air outlet of the third aspect of the present invention, wherein the inner ventilation pipe assembly includes an inner telescopic pipe, and the inner telescopic pipe extends and retracts to drive the inner limiting plate to reciprocate.

[0014] According to the above structure, the displacement generated by the expansion and contraction of the inner telescopic tube is used to compensate for the displacement generated by the reciprocating motion of the part with the inner limiting plate.

[0015] The local humidification air outlet of the fifth aspect of the present invention is based on the local humidification air outlet of the third aspect of the present invention, wherein the inner ventilation duct assembly includes an inner baffle, and the inner baffle is linked with the inner limiting plate to open or close the outer humidification channel.

[0016] Based on the above structure, by setting the inner baffle to be linked with the inner limiting plate to open or close the outer humidification channel, the opening or closing of the outer humidification channel can be achieved through a simple structure.

[0017] The sixth aspect of the present invention provides a local humidification air outlet, which is based on the local humidification air outlet of any one of the first to fifth aspects of the present invention, wherein the outer humidification pipe assembly includes an outer spherical shell. The mounting housing has a curved surface that matches a portion of the spherical housing, and the outer spherical housing of the outer humidification tube assembly is rotatable along the curved surface of the mounting housing.

[0018] Based on the above structure, by adapting the outer spherical shell of the outer humidification tube assembly to the original curved surface of the mounting housing, the direction of the humidified air delivered from the outer humidification tube assembly can be changed through a simple structure.

[0019] The seventh aspect of the present invention is based on the sixth aspect of the present invention, wherein an outer humidification nozzle is provided in the outer spherical shell of the outer humidification pipe assembly, the outer humidification nozzle is recessed relative to the outer surface of the outer spherical shell, and the inner air outlet nozzle of the inner ventilation pipe assembly passes through the outer humidification nozzle and protrudes.

[0020] According to the above structure, by passing through the inner air outlet nozzle and protruding out of the outer humidification nozzle, the air outlet surface of the inner air outlet nozzle and the air outlet surface of the outer humidification nozzle are not on the same plane. Therefore, it is possible to avoid the mixing of high-speed air with a lower humidity than the predetermined humidity emitted from the inner air outlet nozzle and low-speed humid air with the predetermined humidity emitted from the outer humidification nozzle, thereby enabling ventilation and humidification functions to be achieved independently.

[0021] The local humidification air outlet of the eighth aspect of the present invention is based on the local humidification air outlet of the seventh aspect of the present invention, wherein the inner ventilation duct assembly further includes an opening adjustment element, and the switching adjustment element adjusts the opening of the inner air outlet nozzle.

[0022] According to the above structure, the inner ventilation duct assembly also includes an opening adjustment element, which adjusts the opening of the inner air outlet nozzle, thereby adjusting the ventilation volume of the inner ventilation.

[0023] The local humidification air outlet of the ninth aspect of the present invention is based on the local humidification air outlet of any one of the first to fourth aspects and the seventh to eighth aspects of the present invention, wherein a heat insulation layer of fixed thickness is provided on the outer surface of the inner ventilation duct assembly.

[0024] According to the above structure, by providing a heat insulation layer of fixed thickness on the outer surface of the inner ventilation duct assembly, it is possible to avoid condensation on the outer surface of the inner ventilation duct assembly due to the temperature of the humidified air in the outer humidification channel being higher than the temperature of the air in the inner ventilation duct assembly in the standalone humidification mode.

[0025] The tenth aspect of the present invention provides a local humidification method, comprising: an installation step of installing a local humidification vent as described in any one of the first to ninth aspects onto the mounting housing; and an operation step of opening the outer humidification channel by pulling down the inner ventilation duct assembly when local humidification of a target microenvironment is required.

[0026] According to the above method, the local humidification air outlet can be installed on the mounting housing through the installation steps, and the local humidification air outlet can be used to locally humidify the target microenvironment through the action steps.

[0027] The local humidification method of the eleventh aspect of the present invention is based on the local humidification method of the tenth aspect of the present invention, and further includes an adjustment step, wherein the opening of the outer humidification nozzle is adjusted by the opening adjustment element.

[0028] According to the above method, by adjusting the opening of the outer humidification nozzle through the opening adjustment element, different humidification requirements of the target microenvironment can be met. Attached Figure Description

[0034] The present invention will be further described below with reference to specific embodiments and accompanying drawings, but this should not be construed as limiting the scope of protection of the present invention.

[0035] Although the local humidification vents described in the following embodiments are mainly used in the field of aircraft, those skilled in the art will readily understand from the following descriptions that the local humidification vents described in the various embodiments of the present invention can be applied not only to the field of aircraft, but also to other fields such as the cabins of high-speed trains, the driver's cabs of automobiles, and the cabins of ships.

[0036] Descriptions involving orientation, such as the terms "circumferential" and "axial," refer to the circumferential direction of the circular cross-section of the outer humidification duct assembly and the direction of the central axis, respectively, based on the central axis of the circular tube. The terms "outer layer," "inner layer," "inner," and "outer" are used with reference to the aforementioned circular cross-section. The terms "above" and "below" for the local humidification vent 1 described below refer to... Figure 1 , 2 The up and down directions shown are for reference only, and are merely illustrative. The actual directions are determined based on the installation location and direction of the local humidification vent 1.

[0037] It is worth noting that the numerical values ​​given in the following embodiments are merely examples and are not intended to limit the scope of the invention.

[0038] This invention provides a localized humidification vent 1, including a mounting housing 10 for the main body of the device. The term "device" here is narrowly defined as a mounting device for supplying air to a target microenvironment, such as an aircraft cockpit sidewall panel, an overhead luggage rack in an aircraft cabin, a passenger service unit (PSU) above a passenger seat, the upper part of the passenger seat back, the sides of the headrest, or the inside of the armrest. In a broader sense, it can be understood to include all devices used for vent installation. The term "localized" here refers to the cabin environment relative to the overall environment of an aircraft cabin in the prior art. Specifically, in the following description, it refers to the area corresponding to the passenger's head, feet, etc. However, those skilled in the art should understand that "localized" also includes situations where some areas of the target microenvironment require humidification while others do not.

[0039] The following is for reference Figure 1 and Figure 2 The local humidification air outlet of the present invention will be described in detail.

[0040] The local humidification air outlet 1 includes an outer humidification tube assembly 30, which is attached to the mounting housing 10 and used to deliver humidified air with a predetermined humidity to the target microenvironment. It should be noted that "attached" here is not a simple "sticking," but rather a method (not shown) where at least a portion of the outer surface of the outer humidification tube assembly 30 contacts the inner surface of the mounting housing 10 through mechanical connections such as snap-fit ​​or sliding rail nesting. Furthermore, to allow adjustment of the humidification direction of the outer humidification tube assembly 30, it is configured to rotate relative to the mounting housing 10. Figure 1 The diagram illustrates an outer humidification tube assembly 30 comprising an outer spherical shell 34, on the outer surface of which a mounting housing 10 is disposed. The mounting housing 10 includes a curved surface 11 with an inner surface having the same radius of curvature as the outer spherical shell 34. Thus, according to the passenger's personalized humidification requirements, the angle of rotation of the outer spherical shell 34 along the inner surface of the curved surface 11 of the mounting housing 10 can be manually adjusted. An outer humidification nozzle 35 is disposed on the outer spherical shell 34, through which humidified air of a predetermined humidity is delivered to the target microenvironment.

[0041] The inner ventilation duct assembly 20 is nested within the outer humidification duct assembly 30, and an airtight outer humidification channel 33 is formed between the outer surface of the inner ventilation duct assembly 20 and the inner surface of the outer humidification duct assembly 30. The outer humidification channel 33 allows the flow of humidified air with a predetermined humidity, while the inner ventilation duct assembly 20 allows the flow of humidified air with a lower humidity than the predetermined humidity. Although in one embodiment of the present invention the outer humidification channel 33 is formed by the inner surface of the outer humidification duct assembly 30 and the outer surface of the inner ventilation duct assembly 20, it is not limited to this, and the outer humidification duct assembly 30 may independently form a channel for the flow of humidified air.

[0042] The inner ventilation duct assembly 20 is in the direction of airflow inflow (refer to...). Figure 1 The inner layer air inlet pipe 21, inner layer connecting rigid pipe 22, inner layer telescopic pipe 23, inner layer outlet pipe 24, inner layer air outlet nozzle 25, and inner layer limiting plate 26 and inner layer baffle 27 installed around the outer peripheral surface of the inner layer outlet pipe 24 are arranged in sequence in the direction of outflow (left arrow in the middle).

[0043] The outer humidification tube assembly 30 is in the direction of airflow inflow (refer to...). Figure 1 The outer humidification connecting pipe 31, the outer limiting groove 32, the outer humidification flow channel 33, the outer spherical shell 34, and the outer humidification nozzle 35 are arranged sequentially in the outflow direction (as indicated by the downward arrow in the image).

[0044] The aforementioned outer humidification channel 33 is specifically formed by the outer humidification connecting pipe 31, the inner surface of the outer spherical shell 34, the outer surface of the inner connecting rigid pipe 22, the inner telescopic pipe 23 and the inner outlet pipe 24, and the outer humidification nozzle 35 installed at the outlet of the outer spherical shell 34 in an airtight manner.

[0045] Reference Figure 1 The inner ventilation duct assembly 20 is bent at 90° at the inner connecting rigid pipe 22. The upstream side of the inner connecting rigid pipe 22 is fixedly installed to the outer humidification connecting pipe 31 of the outer humidification duct assembly 30, and the downstream side forms an inner telescopic pipe 23. The inner air outlet nozzle 25 is installed at the air outlet of the inner outlet pipe 24 and protrudes through the outer humidification nozzle 35 of the outer humidification duct assembly 30. In addition, although Figure 1 Only 90° is shown, but those skilled in the art will readily understand that the angle at which the inner ventilation duct assembly 20 bends at the inner connecting rigid pipe 22 is not limited to 90°. As long as the ventilation channel inside the inner ventilation duct assembly 20 can be separated from the humidification channel between the outer humidification duct assembly 30 and the inner ventilation duct assembly 20, it can also be set to other angles according to the actual situation.

[0046] In one embodiment of the invention, a corrugated pipe is used as the inner telescopic tube 23, but those skilled in the art will readily conceive of other ways to compensate for axial displacement, including but not limited to metal braided hoses (e.g., made of stainless steel 304, 316L) and non-metal braided hoses (e.g., made of rubber, PTFE).

[0047] An inner limiting plate 26 is provided around the outer peripheral surface of the inner outlet pipe 24 of the inner ventilation pipe assembly 20, and the inner limiting plate 26 extends radially outward from the outer peripheral surface of the inner outlet pipe 24. Correspondingly, an outer limiting groove 32 is provided on the outer humidification connecting pipe 31 of the outer humidification pipe assembly 30. The inner limiting plate 26 extends into the outer limiting groove 32 and can reciprocate axially within the outer limiting groove 32.

[0048] The outer limiting groove 32 can restrict the inner ventilation pipe assembly 20 to move within a certain range in the axial direction.

[0049] Reference Figure 1 The outer humidification flow channel 33 of the outer humidification connecting pipe 31 in the outer humidification pipe assembly 30 is as follows: Figure 1 The dotted arrow in the image shows a 90° bend. Below this bend, an inner baffle 27 extends radially outward from the outer circumference of the inner outlet pipe 24. This inner baffle 27 opens or closes the outer humidification channel 33. Although Figure 1 Only 90° is shown in the figure, but those skilled in the art can interpret it based on their understanding of the concept. Figure 1 It's easy to understand that it could also be from other angles or in other shapes.

[0050] Thus, by extending and retracting the inner telescopic tube 23 along the axial direction, the inner limiting plate 26 and the inner baffle 27 are driven to reciprocate along the axial direction. Specifically, when the inner limiting plate 26 moves to the outer limiting groove 32 to its closest axial side ( Figure 1 When the inner baffle 27 is in the position of the uppermost side of the outer humidification channel 33, it moves to the position of closing the outer humidification channel 33. On the other hand, when the inner limiting plate 26 moves to the other side of the outer limiting groove 32 (the outermost axial side), the inner baffle 27 moves to the position of closing the outer humidification channel 33. Figure 1 When the outer humidification channel 33 is in its lowest position (at the bottommost side), the inner baffle 27 is activated to open the outer humidification channel 33. This allows for the opening and closing of the outer humidification channel 33. To avoid obstructing the flow of humidified air from the outer humidification channel 33 to the outer humidification nozzle 35, those skilled in the art will readily understand that the inner limiting plate 26 should be configured not to impede the flow of humidified air. Furthermore, to reliably achieve the opening and closing, those skilled in the art will readily understand that the inner baffle 27 should be formed with a radial dimension perpendicular to the axial direction larger than the dimension of the outer humidification channel 33.

[0051] Although the opening and closing of the outer humidification channel 33 is achieved by the above-described structure of "inner limiting plate + outer limiting groove + inner baffle" in one embodiment of the present invention, those skilled in the art can easily conceive of other structures to achieve the opening and closing of the outer humidification channel 33 based on the above structure.

[0052] Reference Figure 1 An outer humidifying nozzle 35 is provided at the outlet of the outer spherical shell 34 (downstream side in the figure). The outer humidifying nozzle 35 is recessed relative to the spherical outer surface of the outer spherical shell 34. The inner air outlet 241 of the inner outlet pipe 24 passes through the outer humidifying nozzle 35 and protrudes downward in the figure. An inner air outlet nozzle 25 is provided inside the inner air outlet 241 to deliver air with a humidity lower than the predetermined humidity to the target microenvironment.

[0053] By passing the inner air outlet nozzle 25 through the outer humidifying nozzle 35 and expelling it as described above, the air outlet surface of the inner air outlet nozzle 25 and the air outlet surface of the outer humidifying nozzle 35 are not on the same plane, thereby reliably separating the high-speed air with a humidity lower than the predetermined humidity expelled by the inner air outlet nozzle 25 from the low-speed air with the predetermined humidity expelled by the outer humidifying nozzle 35.

[0054] An adjustment element (not shown) is also provided in the inner air outlet nozzle 25 to adjust the opening degree of the inner air outlet nozzle 25. This allows for adjustment of the airflow rate emitted from the inner air outlet nozzle 25. Based on this, those skilled in the art will readily conceive of also providing an opening adjustment element in the outer humidifying nozzle 35, and using this opening adjustment element to adjust the flow rate of the delivered humidified air. The opening adjustment element includes, but is not limited to, a knob, a limit rod, etc. This allows for flexible adjustment of the flow rate of the mixed air emitted from the outer humidifying nozzle 35 and the inner air outlet nozzle 25.

[0055] According to the local humidification vent 1 described above, it is possible to achieve a separate humidification mode, a separate ventilation mode, and a ventilation + humidification mode.

[0056] When using the standalone humidification mode, such as Figure 1 As shown, the inner ventilation duct assembly 20 is pulled downwards to the inner baffle 27, opening the outer humidification channel 33, while simultaneously adjusting the opening element of the inner air outlet nozzle 25 to close. This allows the outer humidification duct assembly to humidify independently at a predetermined opening, and the direction of humidification can be adjusted by rotating the outer spherical shell 34 relative to the mounting shell 10. In this mode, the temperature of the humidified air inside the outer humidification duct assembly is higher than the temperature of the inner ventilation duct assembly's wall; therefore, condensation may form on the outer surface of the inner ventilation duct assembly 20. To suppress corrosion and bacterial growth caused by this condensation, an insulation layer of a certain thickness is provided on the outer surface of the inner ventilation duct assembly 20.

[0057] When using a separate ventilation mode, such as Figure 2 As shown, the inner ventilation duct assembly 20 is pushed upwards until the inner baffle 27 blocks the outer humidification channel 33. At the same time, the opening adjustment element of the inner air outlet nozzle 25 is opened and adjusted to the specified opening. In this way, the inner ventilation duct assembly can be ventilated independently at the specified opening, and the direction of the inner ventilation can be adjusted by rotating the outer spherical shell 34 relative to the mounting shell 10.

[0058] When in ventilation + humidification mode, the inner ventilation duct assembly 20 should be oriented as a whole towards... Figure 1Pulling down the inner baffle 27 opens the outer humidification channel 33 and adjusts it to the specified opening degree using the opening degree adjustment element. At the same time, the opening degree of the inner air outlet nozzle 25 is also adjusted to the specified opening degree. In this way, the ventilation function of the inner ventilation pipe assembly 20 and the humidification function of the outer humidification pipe assembly 30 can be realized simultaneously.

[0059] According to an embodiment of the present invention, a local humidification vent 1 can simultaneously achieve ventilation and humidification functions through a simple double-layer nested pipe assembly.

[0060] Furthermore, by mounting the outer spherical shell 34 in conjunction with the mounting shell 10 so that it can rotate, the direction of outer humidification and the direction of inner ventilation can be adjusted. Moreover, by adjusting the opening of the outer humidification nozzle 35 of the outer humidification pipe assembly 30 and the inner air outlet nozzle 25 of the inner ventilation pipe assembly 20, the ventilation and humidification functions can be adjusted.

[0061] The air vents, as described above, enable localized humidification of sensitive areas such as the head and face of aircraft occupants, allowing for personalized control of the humidification airflow. This enhances the comfort of the target microenvironment while delivering less humidified air compared to whole-cabin humidification, reducing the volume and weight of the humidification system's water tank and improving aircraft operating economy. Furthermore, humidifying only the target microenvironment, without humidifying equipment or areas near structures, reduces the risk of condensation and the resulting corrosion, bacteria, and odor growth. In addition, the combination of separate ventilation and humidification structures saves installation space on the aircraft, and the shared structure further reduces system weight.

[0062] The local humidification method of the local humidification vent according to the present invention includes an installation step and an action step of local driving of the target microenvironment after the installation step. However, in addition to the above-mentioned installation step and action step, it also includes a manufacturing step and an assembly step before the installation step (for example, a manufacturing step of manufacturing the inner ventilation duct assembly and the outer humidification duct assembly in an insert molding manner and an assembly step of inserting and nesting the inner ventilation duct assembly into the outer humidification duct assembly).

[0063] In the above-mentioned local humidification method, the installation step mainly involves installing the local humidification vent 1 into the mounting housing 10 located in the overhead luggage rack, above the passenger seat, or on the side wall of the aircraft cockpit. The shape of the mounting housing 10 is usually adapted to the shape of the installation location, and the shape of the local humidification vent 1 is adapted to the shape of the mounting housing 10. After installation, the nozzle of the local humidification vent 1 must be accurately oriented towards the target microenvironment.

[0064] After installing the local humidification air outlet 1 into the mounting housing 10, the outer humidification channel 33 can be opened or closed by pulling up or down the inner ventilation duct assembly 20, and the opening degree of the inner ventilation duct assembly can be adjusted by turning the knob or moving the limit rod, so as to switch between the independent ventilation mode, the independent humidification mode and the ventilation + humidification mode.

[0065] When the target microenvironment requires localized humidification, the procedure involves pulling down the inner ventilation duct assembly 20 to open the outer humidification channel 33, thereby delivering humidified air to the target microenvironment. Furthermore, by providing an opening adjustment element on the outer humidification nozzle 35, the opening degree of the delivered humidified air can be adjusted. Thus, localized humidification can be reliably achieved through an integrated structure and simple operation.

[0066] Although the accompanying drawings and text describe the structure of a local humidification vent for humidifying a target microenvironment (not the entire cabin) by means of a local humidification vent installed in the side wall of the aircraft cockpit, overhead luggage racks in the aircraft cabin, above passenger seats, etc., those skilled in the art should understand that the embodiments within the scope of the present invention can be applied to other applications on aircraft that require local humidification and have similar structures and / or functions.

[0067] The foregoing description has already given many features and advantages, including various alternative embodiments, as well as details of the structure and function of the apparatus and methods. This document is intended to be exemplary and is not exhaustive or limiting.

[0068] It will be apparent to those skilled in the art that various modifications can be made within the full scope indicated by the broad superordinate meaning of the terms expressed in the appended claims, particularly in terms of structure, materials, elements, components, shapes, dimensions, and arrangements of components, including combinations of these aspects within the scope of the principles described herein. Such various modifications are intended to be included herein, provided they do not depart from the spirit and scope of the appended claims.
