Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, in particular to an air supply device and an air supply system. Background Art

[0002] The air supply device in the prior art includes an air supply unit and an air outlet grille. The air outlet grille includes a plurality of air guides arranged perpendicularly and parallel to the air supply unit. When the air supply unit is in operation, the air is blown to the air guide unit through the duct under the action of the air supply unit, and then blown into the room through the air guide unit. In this process, a negative pressure area is formed on the rear side of the air outlet grille. Due to the different spatial pressures, the air blown out from the air guide unit flows back to the negative pressure area, thereby realizing indoor air flow.

The following four embodiments are combined Figures 1 to 11 The working process of the air supply device and the air supply system is described in detail.

[0047] First embodiment

[0048] Figure 1 It is a schematic diagram of the air supply device of the embodiment of the utility model installed in the target space; Figure 2 This is one of the structural schematic diagrams of the air supply device of an embodiment of the utility model; Figure 3 This is the second structural schematic diagram of the air supply device of the embodiment of the utility model.

[0049] like Figure 1 , Figure 2 and Figure 3 As shown, the air supply device 100 includes an outer frame 20 , an air outlet grille 10 , an air supply channel, an air supply part and a driving unit 30 .

[0050] The outer frame 20 is arranged on the outer peripheral side of the air outlet grille 10. The outer frame 20 includes a base 21, a first side plate 22 and a second side plate 23 arranged opposite to each other, a top plate and a back plate 24. The outer frame 20 of this embodiment is in the shape of a curved cuboid, and the top plate and the back plate 24 are in the shape of a curved arc. The base 21 and the top plate are arranged opposite to each other in the vertical direction, and along the length direction of the base 21, the first side plate 22 and the second side plate 23 are located on the opposite sides of the base 21. The base 21 has an inner wall surface facing the inner space of the back plate 24 and an outer wall surface on the opposite side, and the back plate 24 is arranged at the inner wall surface of the base 21. The lengths of the first side plate 22, the second side plate 23 and the back plate 24 are adapted to the length of the air outlet grille 10, and the first side plate 22, the second side plate 23, the base 21, the top plate and the back plate 24 constitute the outer frame 20. The side where the first side plate 22 is located is defined as the first side of the outer frame 20 , and the side where the second side plate 23 is located is defined as the second side of the outer frame 20 . The first side and the second side are two opposite sides of the outer frame 20 .

[0051] The air outlet grille 10 is installed on the base 21 and is located in a receiving space enclosed by the first side plate 22 , the second side plate 23 , the top plate and the back plate 24 .

[0052] The base 21 is arranged below the air outlet grille 10, and an air inlet is arranged in the base 21 for air to enter, so that when the air supply device 100 is working, air enters the base 21 from the air inlet. In this embodiment, the air inlet is arranged on the inner wall surface of the base 21, and air can directly enter from the inner wall surface of the base 21, and an air inlet space 500 is formed between the back plate 24 and the wall. In other embodiments, the air inlet can be arranged on the ceiling, and the air intake is realized by communicating with the opening of the inner wall surface of the base 21.

[0053] The air supply unit is arranged in the base 21. After the air entering from the air inlet enters the air supply unit, it enters the air guide unit 11 connected to the air supply unit. The air supply unit is in the shape of a snail shell. The outlet of the air supply unit is provided with more than two branch channels. In this embodiment, four branch channels are provided at the outlet of each air supply unit. Each branch channel is connected to at least one air guide unit 11. In this embodiment, the branch channel can be a hose. The air supply unit can control the flow speed of the air in the air supply channel, thereby controlling the air outlet speed of the air outlet 111, so that the user can adjust it according to actual needs.

[0054] One end of the air supply channel is connected to the air inlet, and the other end of the air supply channel is connected to the air outlet 111. After the air supply unit drives the air to enter from the air inlet, the air is discharged from the air outlet 111 through the air supply channel.

[0055] The air outlet grille 10 is disposed above the base 21 and connected to the air supply portion. The air outlet grille 10 includes a plurality of air guide portions 11 arranged at intervals. For example, the air guide portions 11 extend in the vertical direction and are arranged at intervals, with a certain interval between two adjacent air guide portions 11. The plurality of air guide portions 11 are arranged in a row along the length direction of the base 21.

[0056] The air guide 11 is provided with an air outlet 111 for blowing out air. From the arrangement direction of the air guide 11, the air guide 11 is a long strip structure and is arranged along the vertical direction of the outer frame 20 to form an air outlet grille 10. The air guide 11 includes a first end away from the base 21 and a second end close to the base 21. In addition, a part of the air supply channel is arranged in the air guide 11. That is, the inside of the air guide 11 is a hollow structure, and the hollow structure constitutes a part of the air supply channel. The air outlet 111 faces the air outlet side, and the air outlet side can be the front end facing the air outlet grille 10. The first end of the air guide 11 is away from the air supply part, and the second end is close to the air supply part. In this embodiment, one of the first end and the second end is provided with a main rotating assembly 31, and the other is provided with a slave rotating assembly 32. That is, the first end is provided with a slave rotating assembly 32, and the second end is provided with a main rotating assembly 31; it can also be as shown in this embodiment, the first end is provided with a main rotating assembly 31, and the second end is provided with a slave rotating assembly 32.

[0057] The driving unit 30 drives the air guide 11 to be rotatably disposed in the outer frame 20. That is, the driving unit 30 can adjust the rotation direction of the air guide 11 so that the air guide 11 is inclined or perpendicular to the outer frame 20. The direction of rotation of the air guide 11 changes the air outlet direction of the air outlet 111. The driving unit 30 drives the air guide 11 to rotate so that the air outlet 111 of the air guide 11 can be adjusted to any angle from facing the first side plate 22 to facing the second side plate 23. That is, for example, it can be rotated in the direction facing the first side plate 22, or in the direction facing the second side plate 23. Among them, in this embodiment, the angle of rotation of the air guide 11 from the first side of the outer frame 20 to the second side is less than or equal to 100 degrees, that is, the maximum angle of rotation of the air guide 11 from the direction facing the first side plate 22 to the direction facing the second side plate 23 is 100 degrees. The driving unit 30 enables the air guide 11 to be rotatably arranged in the outer frame 20, and the blowing direction of the air outlet 111 changes with the rotation of the air guide 11. It can be understood that the blowing direction of the air outlet 111 always faces away from the back plate 24. In the case where there are multiple air guides 11, the multiple air guides 11 are divided into a first air guide unit and a second air guide unit along the arrangement direction of the air guides 11, and the first air guide unit is close to the first side plate 22, and the second air guide unit is close to the second side plate 23.

[0058] Preferably, the air guide 11 is tilted, that is, the angle between the surface of the air guide 11 in the vertical direction and the surface of the back plate 24 is not 90 degrees. The rotatable air guide 11 can be used to adjust the local wind in a specific local space in a targeted manner according to the needs of the user or the size and shape of the target space 400. For example, the direction of the air guide 11 at the edge of the air supply device 100 is adjusted separately, so that the wind blows to the corner of the target space 400.

[0059] For another example, the air guide 11 in the first air guide unit discharges air toward the first side, and the air guide 11 in the second air guide unit discharges air toward the second side, so that the multiple air guides 11 discharge air toward both sides of the air supply device 100, that is, in the direction from the air outlet side to the air inlet side, the air guide 11 in the first air guide unit is inclined from the middle of the air supply device 100 to the first side of the air supply device 100, and the air guide 11 in the second air guide unit is inclined from the middle of the air supply device 100 to the second side of the air supply device 100. Thus, a diffused air outlet structure is formed, and air outlets on both sides of the target space 400 are increased.

[0060] For another example, the multiple air guides 11 in the first air guide unit and the second air guide unit all discharge air toward the middle of the air supply device 100, that is, in the direction from the air outlet side to the air inlet side, the air guides 11 in the first air guide unit are inclined from the first side toward the middle of the air supply device 100, and the air guides 11 in the second air guide unit are inclined from the second side toward the middle of the air supply device 100. Thus, a centralized air outlet structure is formed, and the air outlet in the middle of the target space 400 is increased.

[0061] In an embodiment of the utility model, the driving unit 30 drives the air guide part 11 to be rotatably arranged in the outer frame 20, so that the multiple air guide parts 11 of the air outlet grille 10 can discharge air toward one side, both sides or the middle of the target space 400, meeting diverse air outlet requirements.

[0062] In the present embodiment, the outer frame 20 further includes a return air outlet disposed on the side of the outer frame 20. The outer frame 20 may be provided with a return air outlet on one side or on both sides. For example, an opening connected to the accommodating space is formed between the first side plate 22 of the outer frame 20 and the wall extending toward the first side from the back plate 24, and this opening is the return air outlet; or an opening connected to the accommodating space is formed between the second side plate 23 of the outer frame 20 and the wall extending toward the second side from the back plate 24, and this opening is the return air outlet. When the number of the return air outlet is one, this return air outlet is defined as the first return air outlet 25.

[0063] The air guide 11 of this embodiment is tilted in the outer frame 20. Specifically, in the direction from the air outlet side to the air inlet side, the air guide 11 tilts from the first side of the first return air port 25 to the second side away from the first return air port 25, that is, the air is blown out from the air outlet 111 tilted to the second side away from the first return air port 25.

[0064] The ventilation duct forms a passage that enters from the first return air port 25 and is blown out from a certain gap 112 between adjacent air guides 11. After entering from the first return air port 25, the air enters the air inlet side opposite to the air outlet side, which may be toward the rear end of the air outlet grille 10, and finally blows out from the gap 112 between adjacent air guides 11.

[0065] In some other optional embodiments of the utility model, the number of air guides 11 and the number of air supply parts are selectively set according to actual needs, and the embodiments of the utility model do not specifically limit the number of air guides 11 and the number of air supply parts. For example, in a specific embodiment, each air supply part is connected to four air guides 11 arranged at intervals. The air guide part 11 is connected to the air supply part through a bend or a hose. An air supply part is provided in the base 21, and one end of the air supply part is connected to the bend, and the air supply part is used to drive the air at the air inlet to circulate in the air supply channel, so that the air entering from the air inlet is discharged through the air outlet 111 after passing through the bend and the air supply channel.

[0066] When the air supply device 100 is in the working state, air enters the air supply channel from the air inlet and is discharged toward the air outlet side through the air outlet 111. When the air is discharged through the air outlet side, the air around the air outlet 111 is affected by the flow of air discharged from the air outlet 111, resulting in a negative pressure area being formed on the air inlet side opposite to the air outlet side. The negative pressure area of ​​the present embodiment is the space between the air outlet grille 10 and the back plate 24. Since the pressure of the negative pressure area on the air inlet side is lower than the pressure of other areas, the air in the surrounding area is prompted to flow toward the air inlet side, and the air enters the air inlet side from the first return air port 25. The air entering from the first return air port 25 enters the negative pressure area, which is a part of the ventilation duct, and is blown out from the gap 112 between the air guide parts 11.

[0067] In some embodiments of the utility model, the air outlet 111 is configured as a long strip-shaped opening extending along the length direction of the air guide 11. The long strip-shaped opening can cause the air discharged from the air outlet 111 to generate a large disturbance to the surrounding air, thereby promoting the formation of a negative pressure zone. After the air enters the air supply device 100 from the first return air port 25, it is blown out from the gap 112 between adjacent air guides 11, thereby replenishing the air volume, so that the air supply unit can operate at a lower speed under the same air volume, thereby reducing noise.

[0068] Figure 4 This is a schematic diagram of assembling the air outlet grille and the drive unit of an embodiment of the utility model;

[0069] Figure 5 It is a structural schematic diagram of the main rotating assembly of an embodiment of the utility model; Figure 6 It is a structural schematic diagram of a slave rotating assembly according to an embodiment of the utility model.

[0070] like Figure 4 , Figure 5 and Figure 6 As shown, in this embodiment, the driving unit 30 includes a main rotating assembly 31 and a slave rotating assembly 32. The number of the driving units 30 is the same as that of the air guides 11, and a plurality of driving units 30 are connected to a plurality of air guides 11 in a one-to-one correspondence. The following description is made by taking the example that the main rotating assembly 31 is connected to the first end of the air guide 11 and the slave rotating assembly 32 is connected to the second end of the air guide 11.

[0071] The main rotating assembly 31 includes a first fixing member 311 , a rotating motor 313 and a transmission shaft 312 .

[0072] The first fixing member 311 is a plate-shaped body. Optionally, buckles are provided at both ends of the first fixing member 311. The first fixing member 311 is buckled with the first end of the air guide portion 11 through the buckles to fix the first fixing member 311 to the first end. The first fixing member 311 can also be connected to the first end by screwing.

[0073] The rotating motor 313 is a power source for the main rotating assembly 31 to rotate. In this embodiment, it is a servo motor, but it can also be a stepping motor. The transmission shaft 312 is connected to the rotating motor 313 at one end and to the first fixing member 311 at the other end. The transmission shaft 312 drives the air guide 11 to rotate along with the rotation of the driving shaft of the rotating motor 313.

[0074] In addition, in order to make the main rotating assembly 31 rotate more smoothly, a flange, a motor bracket 314 supporting the rotating motor 313, and a separate coupling 315 connecting the rotating motor 313 and the transmission shaft 312 can be provided according to the situation. The motor bracket 314 can be connected to the top plate body of the outer frame 20 by screwing. The other end of the transmission shaft 312 is connected to the first fixing member 311 through a flange.

[0075] The slave rotating assembly 32 includes a second fixing member 321 , a ball bearing member 322 and a sleeve 323 .

[0076] The second fixing member 321 is connected to the second end of the air guide portion 11 . The second fixing member 321 is a hollow structure composed of a plurality of metal sheets, so that when the second fixing member 321 is fixed to the second end, air can pass through the middle of the second fixing member 321 and enter the air guide portion 11 .

[0077] The ball bearing member 322 is disposed below the second fixing member 321 and rotates with the rotation of the main rotating assembly 31. The ball bearing member 322 can reduce the resistance of the rotation, so that the rotation of the air guide portion 11 is smoother.

[0078] The shaft sleeve 323 is arranged on the outer peripheral side of the bearing component, which can play a role in dust prevention and is also conducive to the convenience of installation.

[0079] The driving unit 30 drives the air guide part 11 to rotate. During the rotation, the main rotating component 31 drives the air guide part 11 and the slave rotating component 32 to rotate, so that the air guide part 11 rotates to a preset angle, and the angle of the air guide part 11 can be flexibly adjusted.

[0080] In addition, in other embodiments, when the rotating motor 313 is not running, the air guide portion 11 can also be rotated to a desired state manually.

[0081] Optionally, a sterilization unit may be provided in the base 21 for sterilizing the air in the air supply channel. For example, a filtering component and / or a disinfecting component may be provided in the sterilization unit to sterilize the air in the air supply channel.

[0082] Optionally, an adding portion may be provided in the base 21, which is provided on the upstream side of the air supply portion and is used to release additives into the air in the air supply channel. For example, the released additives may be perfume, incense, or other substances that need to be released into the air.

[0083] Figure 7 This is a schematic diagram of air flow of the air supply device of the first embodiment of the utility model;

[0084] like Figure 7 As shown, in this embodiment, the air supply device 100 is arranged at the right corner of the target space 400. In the direction facing the air outlet 111, the first return air outlet 25 of this embodiment is arranged on the right side of the outer frame 20. The driving unit 30 drives the air guide 11 to rotate, and the air guide 11 rotates from the first side of the first return air outlet 25 to the second side away from the first return air outlet 25 in the direction from the air outlet side to the air inlet side until it stops when it is tilted. For the convenience of description below, the first side of the outer frame 20 of this embodiment is the right side, and the second side of the outer frame 20 is the left side.

[0085] That is, the air outlet 111 faces the left direction away from the first return air outlet 25, and the air blows from the right side to the left side.

[0086] When the air is blown from the right side to the left side, the air flows in the entire space. After blowing from the right side to the far left side, the air flows toward the negative pressure area on the right side, and the air enters the air supply device 100 from the first return air port 25. After entering the air supply device 100, the air is blown out from the gap 112 between two adjacent air guides 11, thereby replenishing the air volume, so that the air supply unit can operate at a lower speed under the same air volume, thereby reducing noise. While achieving air flow inside the space, the air flow on the left and right sides will not be uneven because the air supply device 100 is set on the right side, thereby solving the problem of uneven air flow caused by setting the air supply device 100 on one side, and achieving a uniform air supply effect in the target space 400.

[0087] Second embodiment

[0088] Figure 8 This is a schematic diagram of air flow of the air supply device of the second embodiment of the utility model.

[0089] like Figure 8 As shown, in this embodiment, the air supply device 100 is arranged at the left corner of the target space 400. In the direction facing the air outlet 111, the first air return port 25 of this embodiment is arranged on the left side of the outer frame 20.

[0090] The driving unit 30 drives the air guide 11 to rotate, and the air guide 11 rotates from the first side of the first return air port 25 to the second side away from the first return air port 25 in the direction from the air outlet side to the air inlet side and stops when it is tilted. For the convenience of explanation below, the first side of the outer frame 20 of this embodiment is the left side, and the second side of the outer frame 20 is the right side. That is, the air outlet 111 faces the right direction away from the first return air port 25, and the air blows from the left to the right. The other structures of this embodiment are the same as those of the first embodiment and are not repeated here. In the process of air blowing from the left to the right, the air flow flows in the entire space. After blowing from the left to the far right side, the air flows toward the negative pressure area on the left, and the air enters the air supply device 100 from the first return air port 25. The above-mentioned air flow path realizes the air flow inside the space, and the air flow on the left and right sides will not be uneven because the air supply device 100 is set on the left, thereby solving the problem of uneven air flow caused by the air supply device 100 being set on one side. A uniform air supply effect is achieved in the target space 400.

[0091] Third embodiment

[0092] Fig. 9 This is a schematic diagram of air flow of an air supply device according to the third embodiment of the utility model.

[0093] like Fig. 9 As shown, in this embodiment, the air supply device 100 is arranged on the right side of the target space 400. The outer frame 20 includes a first return air port 25 and a second return air port 26, the first return air port 25 is arranged on the first side of the outer frame 20, and the second return air port 26 is arranged on the second side of the outer frame 20. That is, the first return air port 25 is arranged on the right side of the outer frame 20, and the second return air port 26 is arranged on the left side of the outer frame 20.

[0094] The air outlet grille 10 includes a first air guide unit and a second air guide unit, the first air guide unit includes one or more air guide portions 11, and the second air guide unit includes one or more air guide portions 11. Other structures of this embodiment are the same as those of the first embodiment, and are not described again.

[0095] In the direction from the air outlet side to the air inlet side, the air guide portion 11 in the first air guide unit is tilted from the first return air outlet 25 side to the second return air outlet 26 side, and the air guide portion 11 in the second air guide unit is tilted from the second return air outlet 26 side to the first return air outlet 25 side. That is, the driving unit 30 drives the air guide portion 11 of the first air guide unit to rotate toward the second side, and drives the air guide portion 11 of the second air guide unit to rotate toward the first side. That is, the air guide portion 11 close to the left side tilts from the left side to the right side, and the air guide portion 11 close to the right side tilts from the right side to the left side. After the air is concentrated from both sides of the air supply device 100 and blown out to the middle of the air supply device 100, the air blown out from the left side flows toward the negative pressure area on the left side and enters the air supply device 100 from the second return air outlet 26, while the air blown out from the right side flows toward the negative pressure area on the right side and enters the air supply device 100 from the first return air outlet 25.

[0096] The first and second return air ports 25 and 26 are arranged on both sides of the outer frame 20. The first and second return air ports 25 and 26 increase the amount of air entering the negative pressure area, so that more air can be blown out from the gaps 112 between the plurality of air guides 11, thereby increasing the amount of supplementary air and increasing the overall air volume. This not only realizes the air flow inside the space, but also speeds up the air circulation speed.

[0098] Fourth embodiment

[0099] like Fig.10 and Fig.11 As shown, the utility model also provides an air supply system, the air supply system includes a first air supply device 200 and a second air supply device 300, the first air supply device 200 is arranged at a first position of the target space 400, and the second air supply device 300 is arranged at a second position mirrored to the first position. For example, the first air supply device 200 is arranged at the right corner of the target space 400, and the second air supply device 300 is arranged at the left corner of the target space 400. Secondly, the driving unit 30 drives the air guide 11 to rotate until the surface of the air guide 11 in the vertical direction is perpendicular to the surface where the back plate 24 is located, that is, the angle between the surface of the air guide 11 in the vertical direction and the surface where the back plate 24 is located is 90 degrees. When the back plate 24 is arc-shaped, even if the angle between the surface of the air guide 11 in the vertical direction and the surface where the back plate 24 is located is 90 degrees, the effect of blowing air from the left side of the target space 400 to the right side, or from the right side of the target space 400 to the left side can be achieved. The structures of the first air supply device 200 and the second air supply device 300 are the same as those of the third embodiment, and are not described in detail herein.

[0100] The air inlet of this embodiment is set at the ceiling of the target space 400 away from the outer frame 20, and the air inlet is connected to the air supply device through the air inlet pipe 600. The air supply device forms an air inlet space 500 for the air discharged from the air inlet pipe 600 to enter the air supply device, that is, the air supply channel also includes the air inlet pipe 600 and the air inlet space 500. The air inlet pipe 600 can be connected to the air inlet by setting an air inlet box at the downstream side of the air inlet, that is, the air inlet is set at the bottom of the air inlet box, opposite to the ceiling opening. The air entering the air inlet can smoothly reach the air inlet pipe 600. The air inlet space 500 of this embodiment is composed of the back plate 24 of the air supply device and the wall, forming a triangular space with the wall. After the air enters from the air inlet, it passes through the air inlet pipe 600 and enters the air inlet space 500, and finally enters the air supply device.

[0101] The air inlet includes a first air inlet 210 and a second air inlet 310. The first air inlet 210 is connected to the first air supply device 200 and is arranged on the right side of the ceiling of the target space 400 facing the first air supply device 200, and the second air inlet 310 is connected to the second air supply device 300 and is arranged on the left side of the ceiling of the target space 400 facing the second air supply device 300. The other structures of this embodiment are the same as those of the third embodiment, and are not repeated here.

[0102] The air enters from the first air inlet 210 and the second air inlet 310, and after passing through the air inlet pipe 600, enters the first air supply device 200 and the second air supply device 300 respectively, and then blows out from the respective air outlets 111. The air blown out from the first air supply device 200 is blown out obliquely to the left, and the air blown out from the second air supply device 300 is blown out obliquely to the right, that is, it is blown out toward the middle of the target space 400. After the two air streams meet, the air blown out from the first air supply device 200 enters the first air supply device 200 from the first return air port 25 and the second return air port 26 of the first air supply device 200; the air blown out from the second air supply device 300 enters the second air supply device 300 from the first return air port 25 and the second return air port 26 of the second air supply device 300, which not only realizes the air flow inside the space, but also, under the same power consumption, the air flow speed is faster and the air volume formed is larger, which is conducive to further accelerating the air circulation speed.
