Description

Technical Field

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

[0002] The existing air supply device installed on the ceiling includes an air outlet part formed by two or more juxtaposed air outlet units, an air outlet provided on the air outlet unit, an air inlet of the air outlet unit provided on the air outlet unit, and an air inlet for indoor air to enter. Generally, the air inlet is provided on one side close to one of the air outlet units. When the air supply device operates, indoor air enters the air supply device through the air inlet, and after being blown out through the air outlet, most of the air is inhaled again by the air inlet, forming a circulating air flow. Therefore, with the air outlet part as the center, the air pressure on the side with the air inlet is relatively low, and the air pressure on the opposite side is relatively high. Most of the air blown out from the air outlet far from the air inlet will blow vertically downward, forming a region with relatively high air pressure and flowing to the two side regions. At the same time, the air in the air outlet unit blows from the air inlet of the air outlet unit towards the air outlet. After the air blows out from the air outlet, it still maintains a certain inertia and blows in this direction, that is, from the air inlet of the air outlet unit towards the opposite side. That is to say, the air pressure on the opposite side of the air inlet of the air outlet unit in the indoor space is relatively high. And the air on the side with relatively high air pressure will flow towards the region with relatively low air pressure. Therefore, in the indoor space, the air on the side with relatively high air pressure blows towards the side of the air inlet of the air outlet unit, and then towards the opposite side of the air inlet of the air outlet unit and the direction with relatively low air pressure, thereby pushing the air blown out from the air outlet close to the air inlet side, causing the air flow to shift towards the opposite side of the air inlet of the air outlet unit, resulting in uneven air supply and possibly generating turbulent flow and noise.

[0003] Similarly, even if the air inlet is provided in the middle of the arrangement direction of the air outlet units instead of being biased towards one side, when the air outlet part is provided on one side in the indoor space, in the arrangement direction of the air outlet units, due to the unequal distances between the air outlet part and the two side walls or other obstacles, the air pressures on both sides will also be unequal, thereby causing the problem of air flow deviation.

[0004] When the air outlet part of the air supply device is provided above the bed and the air inlet of the air outlet unit is located at the end of the bed, the above problems will cause some air flow on the side of the air outlet part close to the air inlet to possibly blow directly towards the head of the bed, that is, directly towards the user's head, making the user feel uncomfortable.

[0005] To solve the above problems, generally, air guide vanes are provided at the air outlet, and the air guide vanes are reversely inclined to guide the air flow in the reverse direction, thereby correcting the direction of the air flow. However, when the air blows towards the air outlet at a high speed, it will interfere with the air guide vanes, resulting in turbulent flow and noise, increasing the pressure loss, and reducing the air volume. Summary of the Utility Model

[0006] To solve the above problems, the present utility model provides an air supply device. The air outlet includes a first air outlet and a second air outlet. The second air outlet is closer to the air inlet of the air outlet unit and the low-pressure area side than the first air outlet, which can suppress the phenomenon that the air flow direction on one side of the air outlet deviates due to the air pressure difference on both sides of the air outlet part, achieve the effect of correcting the air flow direction and realizing uniform air supply, and provide a more comfortable air supply experience for users.

[0041] In the description of the present disclosure, it should be noted that unless otherwise clearly specified and limited, the terms "connected" and "coupled" should be understood in a broad sense. For example, it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0042] The present disclosure provides an air supply device for supplying air into a room. The so-called air supply into a room includes, but is not limited to, supplying air into one indoor space or multiple indoor spaces. For the convenience of description, the following embodiments will be described with the case where the air supply device is installed on the ceiling.

[0043] The following will Figures 1 to 12 specifically describe the air supply device of the present utility model.

[0044] Figure 1 is a schematic structural diagram of the air supply device according to an embodiment of the present utility model; Figure 2 is a partial structural diagram of the air supply device according to an embodiment of the present utility model; Figure 3 is a schematic structural diagram of the air outlet part of the first embodiment of the present utility model; Figure 4 is one of the schematic diagrams of the air flow in the air outlet part of the first embodiment of the present utility model; Figure 5 is the second schematic diagram of the air flow in the air outlet part of the first embodiment of the present utility model; Figure 6 is a schematic diagram of the air flow of the air supply device according to the first embodiment of the present utility model.

[0045] Figure 2 In, the area surrounded by the dashed line box is the air outlet part 1. Figure 3 In, the areas surrounded by the two dashed line boxes are the first air outlet area 114 and the second air outlet area 115 respectively. Figure 5 In, the areas surrounded by the two dashed line boxes are the first air outlet area 114 and the second air outlet area 115 respectively.

[0046] As Figures 1 to 6 shown, in this embodiment, an air supply device is disclosed. The air supply device includes an air inlet part for air to enter, an air outlet part 1 for air to be blown out, and an air supply part 2 for sending air from the air inlet part to the air outlet part 1.

[0047] The air inlet part is communicated with the air supply part 2 and includes an air inlet 3 formed by an opening for air to enter. The so-called opening for air to enter means that the source of its air and the target space for air supply are in the same space. That is to say, when the air outlet part 1 of the air supply device supplies air into the indoor space, the air in the indoor space enters the air supply device through the air inlet 3. When the air outlet part 1 of the air supply device supplies air to the outside, the air outside enters the air supply device through the air inlet 3. In this embodiment, the air inlet part includes an air inlet 3 for the air in the target space for air supply to enter, and may also include a fresh air inlet for the air outside the target space to enter. For example, when the air supply part 2 of the air supply device supplies air into the room, the air in the indoor space enters the air supply device through the air inlet 3, and at the same time, the air outside can enter the air supply device through the fresh air inlet.

[0048] In this embodiment, the air inlet 3 is provided on the ceiling. In other embodiments, the air inlet 3 can also be provided at other positions in the indoor space, such as on the wall, on the ground or on the column, etc.

[0049] The air outlet part 1 is connected to the air supply part 2, and the air outlet part 1 includes an air outlet unit 11. In this embodiment, the air outlet part 1 is provided on the ceiling and is connected to the air supply part 2 through a duct 21.

[0050] The air outlet part 1 includes an air outlet unit 11. The air outlet unit 11 is approximately in the shape of a hollow cuboid, forming an air outlet duct for sending air into the room. In this embodiment, the air outlet unit 11 includes a top wall, two oppositely arranged side walls, a bottom wall opposite to the top wall, and inclined side walls connecting the bottom wall and the side walls. The width of the bottom wall is smaller than the width of the top wall. The side walls are perpendicular to the top wall, and a preset angle is formed between the inclined side walls and the top wall. The angle value of the preset angle is not specifically limited. Thus, the top wall, the bottom wall, the two side walls and the two inclined side walls enclose to form the air outlet duct.

[0051] Define the two ends of the air outlet unit 11 along the length direction of the air outlet unit 11 as the first end and the second end of the air outlet unit 11 respectively. The first end of the air outlet unit 11 is the end close to the air supply part 2, and the second end of the air outlet unit 11 is the end far from the air supply part 2.

[0052] The air outlet unit 11 includes an air outlet formed by an opening for air to blow out, and an air outlet unit air inlet 111 formed by an opening for air to enter. In this embodiment, the first end of the air outlet unit 11 is configured with an air outlet unit air inlet 111, and the air outlet unit air inlet 111 is located at the side wall of the air outlet unit 11. The second end of the air outlet unit 11 is a closed structure, and the air outlet is provided on the bottom wall of the air outlet unit 11. The plane where the air outlet is located intersects with the plane where the air outlet unit air inlet 111 is located.

[0053] The air supply part 2 is used to send air from the air inlet part to the air outlet part 1 and includes an air supply unit. When the air supply device operates, air enters from the air inlet part, enters the air outlet part 1 along the duct 21, enters the air outlet unit 11 through the air outlet unit air inlet 111, and then blows out through the air outlet.

[0054] The air outlet part 1 has a length direction and a width direction, and the length direction of the air outlet part 1 is the same as the length direction of the air outlet unit 11. Along the length direction, define the two opposite ends of the air outlet part 1 as the first end 101 and the second end 102 of the air outlet part 1 respectively. The first end 101 and the second end 102 are opposite to each other. Along the width direction, define the two opposite sides of the air outlet part 1 as the first side 103 and the second side 104 of the air outlet part 1 respectively. The first side 103 and the second side 104 are opposite to each other.

[0055] One side of the air outlet part 1 forms a high-pressure area, and the other side forms a low-pressure area. For example, the first side 103 of the air outlet part 1 forms a high-pressure area, and the second side 104 of the air outlet part 1 forms a low-pressure area.

[0056] The high-pressure area is an area with relatively high air pressure formed by the air on the side outside the air outlet part 1 in the direction parallel to the plane where the air inlet 111 of the air outlet unit is located. The so-called direction parallel to the plane where the air inlet 111 of the air outlet unit is located refers to the direction perpendicular to the air flow direction in the air outlet unit 11. In this embodiment, it is the direction perpendicular to the side wall of the air outlet unit 11.

[0057] The low-pressure area is an area with relatively low air pressure formed by the air on the other side outside the air outlet part 1 and opposite to the high-pressure area in the direction parallel to the plane where the air inlet 111 of the air outlet unit is located.

[0058] When the air supply device is operating, the air pressure in the high-pressure area is higher than that in the low-pressure area, and a pressure difference is formed between the high-pressure area and the low-pressure area.

[0059] The air outlet includes a first air outlet 112 and a second air outlet 113.

[0060] The first air outlet 112 is provided on one side of the air outlet part 1 close to the high-pressure area. That is, in the direction from the high-pressure area to the low-pressure area, the first air outlet 112 is closer to the high-pressure area than the second air outlet 113. In this embodiment, the number of the first air outlets 112 is multiple, that is, the openings on multiple adjacent air outlet units 11 form the first air outlet 112. In other embodiments, the first air outlet 112 can also be a single opening. The area surrounded by the first air outlets 112 is defined as the first air outlet area 114.

[0061] The second air outlet 113 is provided on one side of the air outlet part 1 close to the low-pressure area and is closer to the air inlet 111 of the air outlet unit than the first air outlet 112. The second air outlet 113 is provided on the air outlet unit 11 and includes a first side 1131 close to the first end 101 of the air outlet part 1 and a second side 1132 opposite to the first side 1131. In this embodiment, the second air outlet 113 is an approximately rectangular opening. In other embodiments, the second air outlet 113 can also be of other shapes. The so-called second air outlet 113 is closer to the air inlet 111 of the air outlet unit than the first air outlet 112 means that taking the second side 1132 of the second air outlet 113 as a reference, the distance L2 from the points on the second side 1132 to the plane where the air inlet 111 of the air outlet unit is located is less than the distance L1 from the points on the second end 102 of the first air outlet 112 close to the air outlet part 1 to the plane where the air inlet 111 of the air outlet unit is located.

[0062] In this embodiment, the number of the second air outlets 113 is multiple, that is, the openings on multiple adjacent air outlet units 11 form the second air outlets 113. In other embodiments, the second air outlet 113 may also be an opening. The area surrounded by the multiple second air outlets 113 is defined as the second air outlet area 115.

[0063] Furthermore, a pressure difference is formed between the high-pressure area and the low-pressure area. The distance from one end of the second air outlet 113 far from the air inlet 111 of the air outlet unit to the air inlet 111 of the air outlet unit is negatively correlated with the pressure difference. That is, the greater the pressure difference between the high-pressure area and the low-pressure area, the smaller the distance from the second side 1132 of the second air outlet 113 to the plane where the air inlet 111 of the air outlet unit is located in the direction parallel to the plane where the air inlet 111 of the air outlet unit is located.

[0064] Furthermore, in the direction parallel to the plane where the air inlet 111 of the air outlet unit is located, the width of the second air outlet 113 is positively correlated with the pressure difference, that is, the greater the pressure difference between the high-pressure area and the low-pressure area, the greater the width of the second air outlet 113.

[0065] In this embodiment, the second air outlet 113 is composed of multiple openings. Therefore, when the pressure difference between the high-pressure area and the low-pressure area is greater, the distance from the second side 1132 of at least one second air outlet 113 to the plane where the air inlet 111 of the air outlet unit is located is smaller. At the same time, the total width of the second air outlet 113 composed of multiple openings is greater.

[0066] In this embodiment, the air outlet part 1 includes more than two air outlet units 11, and the multiple air outlet units 11 are arranged in parallel in the direction parallel to the plane where the air inlet 111 of the air outlet unit is located. The first air outlet 112 is composed of the openings on multiple adjacent air outlet units 11, and the second air outlet 113 is composed of the openings on multiple adjacent air outlet units 11. An air guiding channel is formed between two adjacent air outlet units 11, and the air guiding channel is beneficial to supplement the air volume.

[0067] In this embodiment, in the direction parallel to the plane where the air inlet 111 of the air outlet unit is located, the air inlet 3 is arranged on one side of the air outlet part 1, and a low-pressure area is formed on one side of the air inlet 3. The so-called air inlet 3 is arranged on one side of the air outlet part 1 means that the air inlet 3 is biased to one side with respect to the air outlet part 1 in the direction parallel to the plane where the air inlet 111 of the air outlet unit is located, that is, on the midline perpendicular to the air flow direction in the air outlet unit 11. This includes the case where the air inlet 3 is arranged on the first side 103 or the second side 104 of the air outlet part 1, and also includes the case where the air inlet 3 is arranged on one side of the first end 101 or the second end 102 of the air outlet part 1 and is biased to one side with respect to the above midline.

[0068] In this embodiment, the air inlet 3 is provided on the second side 104 of the air outlet part 1, and a low-pressure area is formed on one side of the air inlet 3. That is to say, the low-pressure area is located in the area of the second side 104 outside the air outlet part 1. And a high-pressure area is formed on the first side 103 outside the air outlet part 1.

[0069] The following lists multiple embodiments to illustrate the air supply process of the air supply device according to the different positions of the first air outlet 112 and the second air outlet 113 on the air outlet part 1 and the different shapes of the second air outlet 113.

[0070] First Embodiment

[0071] In this embodiment, the first air outlet 112 is close to the high-pressure area, the second air outlet 113 is close to the low-pressure area, and the second air outlet 113 is closer to the air inlet 111 of the air outlet unit than the first air outlet 112. Other structures of the air supply device are as described above and will not be elaborated.

[0072] The number of the first air outlets 112 is multiple, the number of the second air outlets 113 is multiple, the multiple first air outlets 112 in the first air outlet area 114 are flush with respect to the first end 101, and the multiple second air outlets 113 in the second air outlet area 115 are flush with respect to the first end 101.

[0073] When the air supply device operates, under the action of the air supply part 2, indoor air is sucked in from the air inlet 3 and sent to the air outlet part 1. The air blows towards the air outlet part 1 through the pipeline 21, enters the air outlet unit 11 through the air inlet 111 of the air outlet unit, and then blows out into the room through the air outlet.

[0074] Since the air inlet 111 of the air outlet unit is provided at the first end 101 and the air outlet is provided on the bottom wall, the air in the air outlet unit 11 blows out in the direction from the first end 101 to the second end 102 and towards the air outlet side. After being blown out at high speed through the air outlet, it may flow along the direction from the first end 101 to the second end 102.

[0075] In this embodiment, since the air inlet 3 is provided on the second side 104 of the air outlet part 1, therefore, a low-pressure area is formed in the area of the second side 104, and a high-pressure area is formed in the area of the first side 103.

[0076] Since the air pressures on both sides of the air outlet part 1 are different, the air in the high-pressure area will flow towards the low-pressure area. Therefore, after the air is blown out at high speed from the air outlet, the air on the side close to the low-pressure area will flow towards the air inlet 3 side, and the air on the side close to the high-pressure area, due to the higher wind speed, will maintain the original air flow direction and part of it will flow towards the high-pressure area.

[0077] Meanwhile, since the air inlet 111 of the air outlet unit is provided at the first end 101 of the air outlet part 1, the air in the high-pressure area will flow from the side of the second end 102 to the side of the first end 101 and flow toward the low-pressure area side, forming an annular return flow from the second end 102 to the first end 101 and from the first side 103 to the second side 104. Since the second air outlet 113 is arranged close to the low-pressure area side, that is to say, after the air blows out from the air outlet, a part of the air forms a return flow from the second end 102 to the first end 101 and from the first side 103 to the downstream side of the second air outlet 113. As a result, the air blown out from the second air outlet 113 will be pushed by the return air and deviate in the direction of the second end 102 instead of flowing directly below the second air outlet 113. By "deviation", it means that when the second side 1132 of the first air outlet 112 is flush with the second air outlet 113, assuming that the plane M reached by the air blown out from the first air outlet 112 and the second air outlet 113 is the same, the contact area of the air flow blown out from the second air outlet 113 on the plane M is farther from the air inlet 111 of the air outlet unit than the contact area A of the air flow blown out from the first air outlet 112 on the plane M.

[0078] Therefore, in this embodiment, as Figure 3 、 Figure 4 and Figure 5 shown, since the second air outlet 113 is arranged closer to the side of the air inlet 111 of the air outlet unit than the first air outlet 112, that is to say, the distance L2 between the second side 1132 of the second air outlet 113 and the plane where the air inlet 111 of the air outlet unit is located is set to be less than L1. Even if the air blown out from the second air outlet 113 deviates in the direction of the second end 102, it can be close to or even flush with the position of the air flow blown out from the first air outlet 112. That is to say, when the second air outlet 113 is arranged closer to the side of the air inlet 111 of the air outlet unit than the first air outlet 112, in the direction from the first end 101 to the second end 102, the contact area B of the air flow blown out from the second air outlet 113 with the plane M is close to or even flush with the contact area A of the air flow blown out from the first air outlet 112 with the plane M.

[0079] Thus, the phenomenon that the air flow direction at one side of the air outlet deviates due to the air pressure difference on both sides of the air outlet part 1 is suppressed, the air flow direction is corrected, and the effect of uniform air outlet is achieved, providing a more comfortable air supply experience for users.

[0080] In addition, the greater the air pressure difference between the high-pressure area and the low-pressure area, the more air returns to the side of the second air outlet 113, and the greater the deviation of the air blown out from the second air outlet 113 toward the second end 102. Therefore, the greater the air pressure difference between the high-pressure area and the low-pressure area, the smaller the distance L2 between the second side 1132 of the second air outlet 113 and the air inlet 111 of the air outlet unit, thereby suppressing the deviation of the air flow blown out from the second air outlet 113 in the direction from the first end 101 to the second end 102.

[0081] In addition, the greater the air pressure difference between the high-pressure area and the low-pressure area, the greater the width of the second air outlet 113 in the direction parallel to the plane where the air inlet 111 of the air outlet unit is located, thereby suppressing the deviation of the airflow blown out from the second air outlet 113 in the direction from the first end 101 to the second end 102.

[0084] Second Embodiment

[0085] The following describes the second embodiment of the present disclosure. Among them, the same structures as those in the first embodiment will not be repeated.

[0086] In this embodiment, the second air outlet 113 is closer to the air inlet 111 of the air outlet unit than the first air outlet 112. The air outlet includes a first air outlet side close to the first end 101 and a second air outlet side opposite to the first air outlet side. At least a part of the second air outlet side of the air outlet is inclined from the second end 102 of the air outlet part 1 to the first end 101 and towards the low-pressure area. The so-called second air outlet side of the air outlet refers to the side where the connection line formed by connecting the midpoints of the sides of the first air outlet 112 and the second air outlet 113 close to the second end 102 of the air outlet part 1 is located. The second air outlet 113 has a first side 1131 close to the first end 101 and a second side 1132 close to the second end 102. The first air outlet 112 also has a first side close to the first end 101 and a second side close to the second end 102.

[0087] When the first air outlet 112 includes a plurality of openings and the second air outlet 113 includes a plurality of openings, the midpoint connection line of the second sides 1132 of at least two second air outlets 113 is inclined. That is to say, assuming that the first air outlet 112 includes three openings and the second air outlet 113 includes three openings, the three openings of the second air outlet 113 are closer to the air inlet 111 of the air outlet unit than the first air outlet 112. Among the three openings of the second air outlet 113, the opening closest to the first air outlet 112 is arranged farther from the air inlet 111 of the air outlet unit than the other two openings. Alternatively, the three openings of the second air outlet 113 are arranged flush.

[0088] When the second air outlet 113 is formed by a plurality of openings, that is, when the air outlet includes a plurality of second air outlets 113, the midpoint connection line of the second sides 1132 of at least two second air outlets 113 is inclined towards the first end 101 and towards the low-pressure area side.

[0089] The so-called inclined setting includes a state where the second side 1132 of the second air outlet 113 is inclined towards the first end 101 and the low-pressure area, or a state where the second side 1132 of the second air outlet 113 is parallel to the plane where the air inlet 111 of the air outlet unit is located.

[0090] Optionally, as Figure 7 shown, two second air outlets 113 in the second air outlet area 115 close to the second side 104 of the air outlet part 1 are closer to the plane where the air inlet 111 of the air outlet unit is located than the other two adjacent second air outlets 113. The first side 1131 and the second side 1132 of each second air outlet 113 are parallel to each other, and the first side 1131 and the second side 1132 are parallel to the first end 101 of the air outlet part 1. The plurality of first air outlets 112 in the first air outlet area 114 are arranged flush with respect to the first end 101, that is, the distances between the plurality of first air outlets 112 and the first end 101 of the air outlet part 1 are the same. The first side and the second side of each first air outlet 112 are parallel to each other, and the first side and the second side are parallel to the first end 101 of the air outlet part 1.

[0091] Optionally, as Figure 8 shown, the distances between the plurality of second air outlets 113 in the second air outlet area 115 and the first end 101 of the air outlet part 1 are the same. The first side 1131 and the second side 1132 of each second air outlet 113 are inclined towards the first end 101 and towards the low-pressure area side. The plurality of first air outlets 112 in the first air outlet area 114 are arranged flush with respect to the first end 101, that is, the distances between the plurality of first air outlets 112 and the first end 101 of the air outlet part 1 are the same. The first side and the second side of each first air outlet 112 are parallel to each other, and the first side and the second side are parallel to the first end 101 of the air outlet part 1.

[0092] Optionally, asFigure 9 As shown, in the direction from the first side 103 to the second side 104 of the air outlet part 1 (as shown by the D1 direction), a plurality of second air outlets 113 in the second air outlet area 115 are arranged to be gradually closer to the first end 101 of the air outlet part 1 in sequence. The first side 1131 and the second side 1132 of each second air outlet 113 are parallel to each other, and the first side 1131 and the second side 1132 are parallel to the first end 101 of the air outlet part 1. A plurality of first air outlets 112 in the first air outlet area 114 are arranged flush with respect to the first end 101, that is, the distances between the plurality of first air outlets 112 and the first end 101 of the air outlet part 1 are the same. The first side and the second side of each first air outlet 112 are parallel to each other, and the first side and the second side are parallel to the first end 101 of the air outlet part 1.

[0093] Optionally, as Figure 10 shown, in the direction from the first side 103 to the second side 104 of the air outlet part 1 (as shown by the D2 direction), a plurality of second air outlets 113 in the second air outlet area 115 are arranged to be gradually closer to the first end 101 of the air outlet part 1 in sequence. The first side 1131 and the second side 1132 of each second air outlet 113 are inclined towards the first end 101 and towards the low-pressure area side. A plurality of first air outlets 112 in the first air outlet area 114 are arranged flush with respect to the first end 101, that is, the distances between the plurality of first air outlets 112 and the first end 101 of the air outlet part 1 are the same. The first side and the second side of each first air outlet 112 are parallel to each other, and the first side and the second side are parallel to the first end 101 of the air outlet part 1.

[0094] Optionally, as Figure 11 shown, in the direction from the first side 103 to the second side 104 of the air outlet part 1 (as shown by the D3 direction), a plurality of second air outlets 113 in the second air outlet area 115 are arranged to be gradually closer to the first end 101 of the air outlet part 1 in sequence. The first side 1131 and the second side 1132 of each second air outlet 113 are parallel to each other, and the first side 1131 and the second side 1132 are parallel to the first end 101 of the air outlet part 1. The first side and the second side of the first air outlet 112 in the first air outlet area 114 are parallel to each other, and the first side and the second side are parallel to the first end 101 of the air outlet part 1. Thus, the shape of the air outlet is an approximately parallelogram that is inclined towards the first end 101 and towards the low-pressure area side.

[0095] Optionally, as Figure 12As shown, in the direction from the first side 103 to the second side 104 of the air outlet part 1 (as shown by the D4 direction), a plurality of second air outlets 113 in the second air outlet area 115 are arranged gradually closer to the first end 101 of the air outlet part 1 in sequence. The first side 1131 and the second side 1132 of each second air outlet 113 incline towards the first end 101 and towards the low-pressure area side. The first side and the second side of the first air outlet 112 in the first air outlet area 114 incline towards the first end 101 and towards the low-pressure area side. Thus, the shape of the air outlet is a parallelogram that inclines towards the first end 101 and towards the low-pressure area side.

[0096] Optionally, in the direction from the first side 103 to the second side 104 of the air outlet part 1, the second side 1132 of a plurality of second air outlets 113 in the second air outlet area 115 inclines towards the first end 101 and towards the low-pressure area side, and the distance between the first side 1131 and the first end 101 is the same. That is to say, the second air outlet area 115 is an approximate trapezoid with an inclined second side.

[0097] The following describes the specific implementation manners in this embodiment. Among them, the parts that are the same as those in the first embodiment will not be described in detail.

[0098] Due to the different air pressures on both sides of the air outlet part 1, the air in the high-pressure area flows towards the low-pressure area and forms a backflow towards the downstream of the second air outlet 113 and towards the second end 102 side. Among them, the closer to the low-pressure area, the more the air blown out from the second air outlet 113 deflects towards the second end 102 side. If the second sides 1132 of a plurality of second air outlets 113 are arranged flush, even after correction, the contact area of the air blown out near the high-pressure area on the plane M is smaller than that of the air blown out near the low-pressure area on the plane M in terms of the deflection degree. That is to say, even after correcting the deflection, a part of the air blown out from the second air outlet 113 will still deflect.

[0099] Therefore, in this embodiment, at least a part of the second air outlet side of the air outlet inclines towards the first end 101 and towards the low-pressure area. Thus, the deflection of the air blown out from the second air outlet 113 can be better corrected, and further, the deflection of the air blown out from the second air outlet 113 can be suppressed.

[0100] Furthermore, as Figure 12 shown, the air outlet forms a parallelogram with the first side 1131 and the second side 1132 inclining towards the first end 101 and towards the low-pressure area side, which can better suppress the deflection of the air blown out from the air outlet and more precisely correct the deflection of the air blown out from the air outlet.

[0101] Third Embodiment

[0102] The third embodiment of the present disclosure will be described below. Structures that are the same as those in the first embodiment or the second embodiment will not be described in detail.

[0103] In this embodiment, the air supply device is disposed in the indoor space. Specifically, the air outlet portion 1 is disposed on the ceiling and is disposed to be biased toward one side of the indoor space in a direction parallel to the plane where the air inlet 111 of the air outlet unit is located. That is to say, the distance between the air outlet portion 1 and the two side walls or obstacles is not equal with respect to the indoor space. The so-called obstacle refers to an object that can block most of the air flow blown from the air outlet portion 1, such as a cabinet, a column, and the like. In this embodiment, in a direction parallel to the plane where the air inlet 111 of the air outlet unit is located, a high-pressure area is formed in the space on the side where the distance between the air outlet portion 1 and the wall or the obstacle is relatively close, and a relatively low-pressure area is formed on the opposite side thereof.

[0104] The first air outlet 112 is close to the high-pressure area, and the second air outlet 113 is disposed close to the low-pressure area. Moreover, the second air outlet 113 is disposed closer to the air inlet 111 of the air outlet unit than the first air outlet 112. The so-called closer means that the second side 1132 of the second air outlet 113 is disposed closer to the side of the air inlet 111 of the air outlet unit than the side of the first air outlet 112 that is far from the air inlet 111 of the air outlet unit.

[0105] Thus, while correcting the air flow direction, the air supply device can ensure the air volume and suppress the turbulent flow and noise.
