Description

[Technical Field]

[0001] The present application relates to the field of mechatronics, and in particular to air outlets, blowers, blowing devices and vehicles. [Background technology]

[0002] With the development of science and technology, people put forward higher requirements for regulating their environment, and widely use air conditioners, air purifiers and other regulating devices.

[0003] All of the above-mentioned conditioning devices achieve environmental conditioning in the form of supplying air. Therefore, the conditioning devices are provided with an air outlet. For example, as the output end of a vehicle air conditioner, the air outlet in the vehicle is configured to adjust the air volume and direction to achieve the requirements of air circulation and temperature control within the vehicle, and provide a comfortable in-vehicle environment for the driver and passengers.

[0004] However, in order to obtain a large airflow, the existing air outlets are large in size, which not only makes the appearance unattractive but also makes the manufacture and placement very difficult. Summary of the Invention [Means for solving the problem]

[0005] The present application provides an air outlet for reducing the difficulty of manufacturing and arranging the air outlet based on ensuring the airflow volume of the air outlet. The present application also provides a corresponding air blowing apparatus, an air blowing device, and a transportation means.

[0006] According to a first aspect, the present application provides an air outlet including a first mechanical part and a second mechanical part, the first mechanical part and the second mechanical part forming a cavity communicating with an air duct, the air outlet blowing air from the air duct through the cavity, the first mechanical part including a guide part, the second mechanical part including a first surface, the guide part configured to guide air flowing in a first direction into a second direction, the first direction being a direction in which the air flows out of the cavity and the second direction being a direction along the first surface.

[0007] In the present application, the first mechanical part and the second mechanical part form a cavity (gap), the cavity communicates with an air duct, and air (air flow) from the air duct flows into the cavity and then flows out of the cavity to complete the air blowing.

[0008] In this application, based on Bernoulli's principle, the flow velocity (kinetic energy) of the air flowing out of the cavity is high, and the air pressure at the same height (having the same gravitational potential energy) is low, so the surrounding air at the same height can be propelled to flow together, thereby increasing the overall air flow volume.

[0009] In the present application, the guide portion on the first machine portion is configured to guide air flowing in a first direction to flow in a second direction. The first direction is the direction in which the air flows out of the cavity, and the second direction is the direction along the first surface. Specifically, when the air flows out of the cavity from the guide portion, the air flows in the first direction, and based on the Coanda effect, the air deviates from its original flow direction (first direction) and flows in the direction of the protruding object surface (first surface) (second direction). Therefore, the direction along the first surface can be set or adjusted based on a user's requirements to adjust the direction in which the air flows out.

[0017] In a possible embodiment of the first aspect, the angle formed by the first direction and the second direction is less than 90 degrees.

[0018] In this possible embodiment, the angle formed by the first direction and the second direction is less than 90 degrees to ensure that the Coanda effect is applicable to the air outlet and to improve the feasibility of the solution.

[0019] In a possible embodiment of the first aspect, the cavity has a width of 30 millimeters or less.

[0020] In this possible embodiment, the width of the cavity is less than 30 millimeters to ensure that Bernoulli's principle is applicable to the air outlet and to improve the feasibility of the solution.

In addition, based on the structural characteristics of the air outlet, effects such as soft air blowing and uniform temperature can be achieved.

DETAILED DESCRIPTION OF THE INVENTION

[0046] Hereinafter, embodiments of the present application will be described with reference to the accompanying drawings. It is clear that the described embodiments are only a part, not all, of the embodiments of the present application. Those skilled in the art can understand that with the development of technology and the emergence of new scenarios, the technical solutions provided in the embodiments of this application can also be applied to similar technical problems.

[0047] In the specification, claims, and accompanying drawings of this application, the terms "first," "second," etc. are intended to distinguish between similar objects, but do not necessarily indicate a particular order or sequence. It should be understood that such designated elements may be interchanged where appropriate, and that the embodiments described herein may be implemented in sequences other than those illustrated or described herein. Furthermore, and in addition, the terms "comprise" and "have," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or device that includes a list of steps or units is not necessarily limited to those explicitly listed steps or units, but may include other steps or units not explicitly listed, or other steps or units not inherent to such process, method, product, or device.

[0048] The embodiments of the present application provide an air outlet for reducing the difficulty of manufacturing and arranging the air outlet based on ensuring the airflow volume of the air outlet. The embodiments of the present application also provide a corresponding air blowing apparatus, an air blowing device and a transportation means. The details will be described individually below.

[0049] In the following, terms and concepts in the embodiments of the present application are explained and described.

[0050] (1) Coanda effect The Coanda effect is the tendency of a fluid (water or air) to deviate from its original flow direction and flow along a protruding surface, as shown in Figure 1. When there is surface friction (sometimes called fluid viscosity) between the fluid and the surface it is flowing through, the fluid will flow along the surface as long as the curvature is small. For example, air flows along a curved wall, as shown in Figure 1.

[0051] (2) Bernoulli's principle Bernoulli's principle is essentially the law of conservation of mechanical energy in a fluid, as shown in Figure 2. In short, kinetic energy + gravitational potential energy + pressure potential energy = constant. Furthermore, there is a well-known corollary that when a fluid flows at the same height, a faster flow rate indicates a lower pressure.

[0052] In the following, an example is used to illustrate the application scenario in the embodiments of the present application.

[0053] With the development of science and technology, people have higher requirements for regulating their environment, and air conditioners, air purifiers, and other environmental conditioning devices are widely used. All of these conditioning devices achieve environmental conditioning by supplying air. Therefore, these conditioning devices are equipped with air outlets. For example, a central air conditioner located at the top of a room delivers air to users from above through an air outlet. However, most air outlets are large, making them difficult to manufacture and install and resulting in an unattractive appearance. Therefore, how to optimize air outlets has become an urgent issue that needs to be resolved.

[0054] Specifically, using a vehicle application scenario as an example, as shown in Fig. 3, in addition to the conventional arrangement of air outlets on the dashboard and behind the handrail of the center console, air outlets may be additionally provided at the rear row positions on the ceiling of the vehicle to deliver air for passengers in the rear rows (such as the second and third rows of the vehicle) from above, thereby further improving the experience value of the passengers in the rear rows.

[0055] As shown in Figures 4A and 4B, a ceiling typically includes a ceiling body, ceiling supports, and ceiling accessories. The air outlet typically includes tabs, fins, connecting rods, housings, etc., and is installed on the ceiling and connected to an air duct. The user adjusts the air direction up, down, left, or right using the tabs. One end of the air duct is typically connected to the air outlet, and the other end is connected to the vehicle's air conditioner. Furthermore, the air outlet may be further disposed in the surrounding structure of the ceiling, such as the top cover metal sheet or the glass of a sunroof or panoramic glass roof.

[0056] However, because the air outlets are located at a high position, it is inconvenient for passengers to lift their hands to adjust them. The air outlets can only blow air from a single point from a designated location, which limits the position and angle, resulting in concentrated temperature changes and wind speed. As a result, the local somatosensory experience is highly concentrated and uneven (for example, the air outlet blows air onto the head, resulting in high local wind speed and low temperature at the head, causing discomfort to the passenger). Furthermore, because components such as the air outlet, handles, reading lights, and speakers are concentrated on the ceiling of the vehicle, the exterior is cluttered and unattractive. Furthermore, in summer, when the vehicle is exposed to sunlight, users enter the vehicle, open the windows, and turn on the air conditioner. However, because the air outlet is blown from a single point, air convection is slow, hot air dissipates slowly, and the temperature drops slowly.

[0057] Vehicle manufacturers face challenges in arranging components such as air vents, handles, reading lights, speakers, air ducts, and curtain airbags in the rear seats of the vehicle. Furthermore, the placement of air vents near the curtain airbags poses a safety risk in that the air vents may fly out and injure someone when the curtain airbag inflates.

[0058] The following describes in detail the air outlet, air blower, air blowing device and vehicle provided in the embodiments of the present application with reference to the aforementioned application scenarios.

[0059] As shown in FIG. 5, one embodiment of the blower provided in the embodiments of the present application includes a first mechanical portion 110 and a second mechanical portion 120 .

[0060] First mechanical portion 110 and second mechanical portion 120 form a cavity 130 that communicates with an air duct (not shown, but it should be understood that the air duct may communicate with any location of the air outlet). The air outlet blows air from the air duct through cavity 130. First mechanical portion 110 has a guide portion 111, and second mechanical portion 120 has a first surface 121, which is configured to guide air flowing in a first direction to flow in a second direction, where the first direction is the direction in which the air flows out of the cavity and the second direction is along the first surface.

[0061] Specifically, the first mechanical part and the second mechanical part form a cavity (gap), the cavity is connected to an air duct, and air (air flow, e.g., gas flow) from the air duct flows into the cavity and then flows out of the cavity, completing the air blowing.

[0062] See Bernoulli's principle in Figure 2. Because the air flow velocity (kinetic energy) of the air leaving the cavity is high and the air pressure at the same height (same gravitational potential energy) is low, the surrounding air at the same height is propelled to flow together, increasing the overall airflow.

[0063] Optionally, to ensure that Bernoulli's principle is applicable to the air outlets provided in the embodiments of the present application, the width of the cavity is 30 millimeters or less.

[0064] Furthermore, the guide portion of the first machine portion is configured to guide the air flowing in a first direction to flow in a second direction. The first direction is the direction in which the air flows out of the cavity, and the second direction is the direction along the first surface. Specifically, when the air flows out of the cavity from the guide portion, the air flows in the first direction. Referring to the Coanda effect shown in FIG. 1, the air deviates from its original flow direction (first direction) and flows in the direction of the protruding object surface (first surface) (second direction). Therefore, the direction along the first surface can be set or adjusted based on a user's requirements to adjust the direction in which the air flows out.

[0065] Optionally, to ensure that the Coanda effect is applicable to the air outlets provided in the embodiments of the present application, the angle formed by the first direction and the second direction is acute and less than 90 degrees.

[0066] Optionally, as shown in Figure 6, the air outlet further includes a first control portion 112 and a second control portion 122. The first control portion 112 is configured to control the guide portion 111 to adjust the first direction and width of the cavity 130, and the second control portion 122 is configured to control the second machine portion 120 to adjust the second direction and width of the cavity 130.

[0067] Specifically, the first control portion and the second control portion may be electrically connected to a control unit in a device in which the first control portion and the second control portion are integrated. For example, in a vehicle, the first control portion and the second control portion may be connected to a control system of the vehicle, such as a microcontroller unit (MCU). A user may control the first control portion and the second control portion via a control panel of the vehicle to change the width, the first direction, and / or the second direction of the cavity.

[0068] It should be understood that the first and second mechanical portions may be made of a flexible, soft material, since the first and second control portions can control and move the first and second mechanical portions, respectively. Alternatively, the first mechanical portion may be divided into two portions connected by the first control portion, and the first control portion may be moved to thereby form an angle between the two portions. The same is true for the second mechanical portion and the second control portion.

[0069] It should be understood that the width of the cavity may vary throughout the cavity. The width of the cavity in the embodiments of this application is the width of the cavity at the end point, i.e., the width of the cavity at the location where the air exits the cavity.

[0070] The first control part is disposed on the first mechanical part, and the first control part may specifically control the guide part of the first mechanical part. Since the first direction in which air flows out of the cavity is determined by the orientation of the guide part, the first control part may adjust the first direction by controlling the movement of the guide part. Furthermore, adjusting the orientation of the guide part changes the width of the cavity accordingly, thereby adjusting the airflow rate of the air outlet.

[0071] Similarly, the second control portion is disposed on the second mechanical portion, and the second control portion can specifically control the second mechanical portion to move in order to adjust the second direction. When the direction of the first surface of the second mechanical portion is adjusted, the width of the cavity also changes accordingly, thereby adjusting the airflow rate of the air outlet.

[0072] 7, second machine portion 120 includes a first portion 123 used to form cavity 130 and a second portion 124 disposed outside cavity 130. Second control portion 122 is configured to control first portion 123 to adjust the width of cavity 130. Second control portion 122 is further configured to control second portion 124 to adjust the second direction.

[0073] The first part forms a cavity and is located within the second machine part, while the second part is located outside the cavity and within the second machine part. Figure 7 shows that when the second control part controls the movement of the first part, no air flows out of the cavity. Therefore, in this case, only the width of the cavity is changed, or in other words, the airflow rate of the air outlet is changed. When the second control part controls the movement of the second part, air flows out of the cavity. In this case, the air flows along the first surface of the second part based on the Coanda effect. When the second control part controls the orientation of the first surface of the second part to change, the subsequent air flow direction also changes accordingly.

[0074] From the above embodiments, it can be seen that the air outlet provided in the embodiments of the present application can bring about, but is not limited to, the following three beneficial effects:

[0075] (1) The air outlet formed by two mechanical parts is not only simple in structure, but also has a good appearance and is easy to install.

[0076] (2) Based on Bernoulli's principle and the Coanda effect, air is sent through the cavity to propel the surrounding airflow, resulting in the effect that the airflow is greater than the intake airflow.

[0077] (3) The control portion adjusts the first direction, the second direction, and the width of the cavity, thereby making it possible to adjust the airflow direction and airflow rate of the air outlet, thereby enhancing the user's experience.

[0078] 8A and 8B, one embodiment of the air blowing device provided in the present application includes an air blowing port 100. The air blowing port 100 may be the air blowing port shown in FIGS. 5 to 7 described in the above embodiment.

[0079] Specifically, the air blowing device may be a furniture electrical device, such as the air conditioner 200 shown in FIG. 8A, specifically a central air conditioner, or may be the air purifier 300 shown in FIG. 8B.

[0080] In the embodiment of the present application, when the air outlet shown in Figures 5 to 7 is installed in an air conditioner or air purifier, the air outlet has a simple structure, thereby reducing the manufacturing cost and difficulty of the air conditioner or air purifier. Furthermore, because the cavity width of the air outlet provided in the present application is small, when the air outlet is used in previous furniture equipment, the structure of the air outlet is easily concealed, resulting in a more elegant appearance. In addition, based on the structural characteristics of the air outlet, effects such as soft airflow and temperature uniformity can be achieved.

[0081] The blowing device provided in this embodiment of the present application has the same embodiments and beneficial effects as the aforementioned blowing outlet, and the details will not be described again in this embodiment of the present application.

[0082] As shown in FIG. 9, one embodiment of the air blower provided in the embodiment of the present application includes an air duct 400 and the air outlet 100 shown in FIGS. 5 to 7 and described in the above embodiment.

[0083] Specifically, the blower device provided in the embodiment of the present application can be used in a means of transportation, such as a vehicle. As shown in Fig. 10, the blower device further includes a ceiling structure 500. The ceiling structure 500 can be a ceiling structure that needs to be installed in a vehicle. The ceiling structure 500 includes a ceiling support 501 and a ceiling body 502. The air outlet 100 is installed in the ceiling structure 500, specifically, can be installed in the ceiling support 501 of the ceiling structure 500. The air outlet 100 is further connected to an air duct 400, one end of which is connected to the air outlet 100 and the other end of which is connected to an air conditioner of the vehicle.

[0084] Optionally, when the air outlet is installed in the ceiling structure and the air blower device is manufactured, the air outlet, air duct, and ceiling structure may be manufactured separately and then integrated using a secondary installation method. For example, the air outlet is disassembled and then integrated with the ceiling support, ceiling body, sunroof glass, fixed glass sunroof or top cover metal sheet, and air duct using a secondary installation method. The installation method may be clamping, welding, screwing, adhesive, etc. In addition, the air outlet and the ceiling structure may be integrally formed, and the air outlet and air duct may be integrally formed. Alternatively, as shown in FIG. 11 , the air outlet 100, air duct 400, and ceiling structure 500 may be integrally formed. Specifically, the air outlet 100, air duct 400, and ceiling support 501 are integrally formed, and the ceiling support 501 and ceiling body 502 are integrally formed. The integration of multiple components and mechanical parts reduces the manufacturing costs of the blower and improves production efficiency in the supply chain.

[0085] For example, when the air outlet and the ceiling structure are integrally formed, a closed ring-shaped structure is formed along the ceiling opening. In addition to supporting and reinforcing the ceiling and ensuring the contour and rigidity of the ceiling opening, the ceiling support may form a hollow structure inside the upper support after integration to achieve the function of an air duct or air passage. The airflow from the air conditioner's air duct may be guided within the ring-shaped structure of the entire ceiling support, and the air outlet blows the airflow within the hollow structure into the interior of the vehicle driver's seat.

[0086] Optionally, as shown in Figures 12A to 12C, the shape of the air blower is either a ring shape, a U shape, or a linear shape, i.e., the shape is a "-", "=", "U", or "square" shape. In order to realize the air outlet covering a wide area, solve the problem of unpleasant experience caused by the concentration of air temperature and air volume at a single point, and improve the user experience, the air outlet may be provided with a plurality of the aforementioned shapes.

[0087] For example, in accordance with the above-described embodiment in which the air outlet is integrated with the ceiling structure, the shape of the ceiling structure is either a ring shape, a U shape, or a straight shape. The airflow in the air duct flows into the hollow structure of the ceiling structure, exits through the multiple air outlets integrated with the hollow structure, and is blown out to multiple positions, for example, within the vehicle cab.

[0088] Optionally, the air duct may be further connected to another functional device in the vehicle, for example, to at least one of an air humidifier, an air purifier, and an air freshener, so that the air outlet blows out various air flows, thereby expanding the versatility of the air outlet's functions.

[0089] The blower device provided in this embodiment of the present application has the same embodiments and beneficial effects as the aforementioned blower, and the details will not be described again in this embodiment of the present application.

[0090] From the above embodiments, it can be seen that the air outlet provided in the embodiments of the present application can bring about, but is not limited to, the following four beneficial effects:

[0091] (1) This air outlet is used in a ceiling structure device to solve the problems of difficult placement, unsightly appearance, and tendency to come off when the curtain airbag is inflated.

[0092] (2) The air outlet, air duct and ceiling structure can be installed separately or integrally formed to reduce the manufacturing cost of the air blower and improve the production efficiency of the supply chain.

[0093] (3) When the air blowing device has a different shape, the air outlet can cover a wide area to solve the problem of unpleasant experience caused by the concentration of air temperature and air volume at a single point and improve the user experience.

[0094] (4) The air duct communicating with the air outlet can be connected to various devices based on user requirements, so that the air outlet can blow out various air flows, thereby increasing the versatility of the air outlet's functions.

[0095] As shown in Fig. 13, one embodiment of a vehicle 600 provided in the embodiments of the present application includes a blower 700. The blower 700 may be the blower shown in Figs. 9 to 12C described in the previous embodiments. The vehicle 600 may be a vehicle, a ship, an airplane, a train, or the like, and the blower 700 is installed on the top of the vehicle 700.

[0096] Specifically, when the means of transportation is a vehicle, the invisible (strip-shaped, 3 to N polygonal, or irregularly shaped) blower may be positioned at the vehicle's ceiling opening, ceiling support, ceiling body, sunroof glass, fixed glass sunroof, or top cover metal sheet (or beam / longitudinal beam).

[0097] The air outlet or blower device provided in the embodiments of the present application is placed in a vehicle, so that the conventional air outlet in the ceiling is removed and a new hidden air outlet is added based on the sunroof opening in the ceiling. The air outlet and ceiling support can be designed as an integrated cavity component (by injection molding, stamping, etc.). The air outlet is connected to the vehicle's overall air duct through 1 to N air intake channels (N is a positive integer). After entering the air outlet through the intake channels, the air flow in the vehicle's overall air duct is blown out from the air outlet's blowing cavity. Based on Bernoulli's principle and the Coanda effect, the blown air flow propels the surrounding air to flow together, forming a wide-ranging, gentle air and temperature flow within the vehicle's cab.

[0098] In addition, there is no need to manually adjust the air outlet, and the airflow can form a natural circulation within the driver's seat. The air outlet has a low-speed, full-area airflow area and angle, and the temperature and wind speed are uniform and imperceptible. Convection within the driver's seat is quickly formed, followed by a rapid temperature drop or rise. The appearance is hidden, simple, and high-end, and there is no risk of inflation when the air outlet is separated from the curtain airbag.

[0099] The transportation means provided in this embodiment of the present application has the same embodiments and beneficial effects as the above-mentioned blower device, and the details will not be described again in this embodiment of the present application.

[0100] In the present application, the term "vehicle" may include road transport, water transport, air transport, industrial equipment, agricultural equipment, recreational equipment, etc. For example, the vehicle may be a vehicle. The vehicle is a vehicle in a broad sense and may be a transportation vehicle (such as a commercial vehicle, a passenger car, a motorcycle, an aircraft, or a train), an industrial vehicle (such as a forklift, a trailer, or a tractor), a construction vehicle (such as a hydraulic excavator, a bulldozer, or a crane), an agricultural machine (such as a lawn mower or a harvester), a recreational device, or a toy vehicle. The type of vehicle is not particularly limited in the embodiments of the present application. As another example, the vehicle may be a transportation vehicle such as an aircraft or a ship.
