[0028] The utility model provides a multi-chamber air distribution device. Figures 1 to 3 The multi-chamber air distribution device of the utility model is described in detail.

[0029] Figure 1 It is a perspective view of a multi-chamber air distribution device according to the first embodiment of the utility model; Figure 2This is a front view of the multi-chamber air distribution device of the first embodiment of the utility model (partial structure is not shown).

[0030] First embodiment

[0031] like Figure 1 and Figure 2 As shown, an embodiment of the utility model provides a multi-chamber air distribution device, which includes a shell 1, a main air inlet 110, an air outlet and a rectifier plate 2.

[0032] The housing 1 includes a top wall, a bottom wall, and a plurality of side walls connecting the top wall and the bottom wall. Optionally, the housing 1 is a square housing, and the number of side walls is four. The number of side walls may also be more than four. When the number of side walls is four, the four side walls are defined as a first side wall 11, a second side wall 12, a third side wall 13, and a fourth side wall 14. The first side wall 11 and the second side wall 12 are arranged opposite to each other, and the third side wall 13 and the fourth side wall 14 are arranged opposite to each other.

[0033] The main air inlet 110 is arranged in the middle of the first side wall 11 of the housing 1, and air enters the multi-chamber air distribution device from the main air inlet 110. In this embodiment, only one main air inlet 110 is provided, and in other embodiments, a secondary air inlet may be provided, and the secondary air inlet may be provided on the peripheral side of the main air inlet 110.

[0034] There are multiple air outlets. The air entering the multi-chamber air distribution device is discharged from the air outlet, and the air outlet can be connected to an air valve or an air duct to deliver the air to the corresponding rooms. According to the different positions of the air outlets on the side wall, the air outlets include a main air outlet 120 and a side air outlet 130. There are multiple main air outlets 120, and there are one or more side air outlets 130.

[0035] According to the number of rooms, an air outlet cover 3 of the same size as the air outlet can be used to close the rooms that do not need air intake. This embodiment uses a rotating air outlet cover 3. When the air outlet needs to be opened to connect the air valve, the air outlet cover 3 is rotated counterclockwise, and the air outlet cover 3 can be taken out from the air outlet. After the air outlet cover 3 is taken out, the air valve is installed at the air outlet; when the air outlet needs to be closed, the air valve is removed, and the air outlet cover 3 is then covered with the air outlet, and the air outlet cover 3 is rotated clockwise until the air outlet cover 3 is fastened to the air outlet.

[0036] The diameter of the main air inlet 110 is greater than the diameter of any main air outlet 120, that is, the air volume entering the main air inlet 110 is greater than the air volume discharged from any main air outlet 120. The diameter of the main air inlet 110 is greater than the diameter of any side air outlet 130, that is, the air volume entering the main air inlet 110 is greater than the air volume discharged from any side air outlet 130.

[0037] The main air outlet 120 is arranged on the second side wall 12 of the shell 1. The second side wall 12 has a length direction and a width direction. The width direction is consistent with the height direction of the multi-chamber air distribution device. Along the length direction of the second side wall 12, the entire area of ​​the second side wall 12 is divided into a middle area and two edge areas located on both sides of the middle area. The two edge areas are respectively a left edge area and a right edge area. According to the distribution area of ​​the multiple main air outlets 120 on the second side wall 12, the main air outlet 120 includes a first main air outlet 121 and a second main air outlet 122. The first main air outlet 121 is located in the middle area of ​​the second side wall 12, and the second main air outlet 122 is located in the edge area of ​​the second side wall 12.

[0038] The at least one first main air outlet 121 and the plurality of second main air outlets 122 may be arranged in a single row or multiple columns, or may be arranged in multiple rows or multiple columns.

[0039] For example, there is one first main air outlet 121 and two second main air outlets 122 , one second main air outlet 122 is located at the left edge area of ​​the second side wall 12 , and the other second main air outlet 122 is located at the right edge area of ​​the second side wall 12 .

[0040] For example, the number of the first main air outlets 121 is two, the number of the second main air outlets 122 is four, and the two first main air outlets 121 and the four second main air outlets 122 are arranged in two rows and three columns. That is, the two first main air outlets 121 are arranged at intervals in the middle area of ​​the second side wall 12 along the width direction of the second side wall 12, the two second main air outlets 122 are arranged at intervals in the left edge area of ​​the second side wall 12 along the width direction of the second side wall 12, and the two second main air outlets 122 are arranged at intervals in the right edge area of ​​the second side wall 12 along the width direction of the second side wall 12.

[0041] The rectifier plate 2 is arranged on the downstream side of the main air inlet 110 and is arranged parallel to the plane where the main air inlet 110 is located. The rectifier plate 2 is located between the first side wall 11 and the second side wall 12, and the rectifier plate 2 can be connected to the side wall of the shell 1 by screwing, clamping, etc. The length dimension of the rectifier plate 2 is adapted to the spacing between the third side wall 13 and the fourth side wall 14, and the width dimension of the rectifier plate 2 is adapted to the spacing between the top wall and the bottom wall. The rectifier plate 2 rectifies the air entering from the main air inlet 110. The width direction of the rectifier plate 2 is consistent with the height direction of the multi-chamber air distribution device. Along the length direction of the rectifier plate 2, the entire area of ​​the rectifier plate 2 is divided into a middle area and two edge areas located on both sides of the middle area, and the two edge areas are respectively a left edge area and a right edge area.

[0042] The rectifier plate 2 is provided with a plurality of ventilation holes 200. The shape of the ventilation holes 200 may be a combination of one or more of a circular shape, an elliptical shape, a square shape, a long strip shape, etc. The shape of the ventilation holes 200 and the arrangement of the ventilation holes 200 may be set so that the air flow rate flowing to the two edge areas of the rectifier plate 2 is similar to the air flow rate flowing to the middle area of ​​the rectifier plate 2.

[0043] When the rectifier plate 2 is not set, since the main air outlet 120 located in the middle area of ​​the second side wall 12 is opposite to the main air inlet 110, after the air enters the multi-chamber air distribution device from the main air inlet 110, most of the air is directly blown to the main air outlet 120 in the middle area of ​​the second side wall 12, and a small amount of air is blown to the main air outlet 120 in the edge area, resulting in uneven air volume delivered to each room.

[0044] In the embodiment of the present disclosure, after the air enters the multi-chamber air distribution device from the main air inlet 110, it will not blow directly to the main air outlet 120, but will first contact the rectifier plate 2 arranged on the downstream side of the main air inlet 110. The multiple ventilation holes 200 on the rectifier plate 2 make the area of ​​the middle area of ​​the rectifier plate 2 that blocks the air from the upstream side of the rectifier plate 2 to the downstream side of the rectifier plate 2 larger than the area of ​​the edge area of ​​the rectifier plate 2 that blocks the air from the upstream side of the rectifier plate 2 to the downstream side of the rectifier plate 2. Therefore, when the air reaches the middle area of ​​the rectifier plate 2, more air will flow to the two edge areas of the rectifier plate 2 with less resistance, so that the air flow in the middle of the downstream side of the rectifier plate 2 is close to the air flow on both sides, avoiding the wind from blowing concentratedly to the main air outlet 120 in the middle area opposite to the main air inlet 110, thereby achieving a uniform wind effect. The rectified wind will be evenly discharged to the main air outlet 120 in the middle area and the main air outlet 120 in the edge area, and then sent to each room through the pipes connected to the main air outlet 120, avoiding the problem of uneven air supply in each room and ensuring that the air volume sent to each room is relatively balanced. In addition, the wind after rectification flows more smoothly, which is conducive to reducing noise.

[0045] In an embodiment of the present disclosure, a main air inlet 110 and a main air outlet 120 are respectively provided on the first side wall 11 and the second side wall 12 of the shell 1, and the rectifier plate 2 is located between the first side wall 11 and the second side wall 12. The multiple ventilation holes 200 provided on the rectifier plate 2 enable the air entering from the main air inlet 110 to flow evenly to the middle area and edge area of ​​the rectifier plate 2, and then enable the air flowing through the rectifier plate 2 to flow evenly to the main air outlet 120 located in the middle area and edge area of ​​the second side wall 12, thereby achieving a uniform air supply effect to multiple rooms.

[0046] like Figure 1 and Figure 2As shown, in an optional embodiment, the ventilation hole 200 is in the shape of an elongated strip. When the size of the rectifier plate 2 is constant, the elongated ventilation hole 200 is conducive to maximizing the ventilation area, and is also conducive to guiding the stable flow of air. The hole wall of the ventilation hole 200 is formed by a rectangle and two arcs, that is, two spaced straight segments and two arc segments are formed to form the hole wall of the ventilation hole 200, and the arc segment can be a semicircle. The width between the two straight segments is set according to actual needs, and the length of the straight segment and the curvature of the arc segment are set according to actual needs.

[0047] The plurality of ventilation holes 200 are arranged at intervals on the rectifying plate 2, that is, a spacing is provided between two ventilation holes 200, and the spacing blocks air from blowing from the upstream side of the rectifying plate 2 to the downstream side of the rectifying plate 2. The plurality of ventilation holes 200 on the rectifying plate 2 can be arranged in a single row and multiple columns, or in multiple rows and multiple columns.

[0048] Along the length direction of the rectifier plate 2, the entire area of ​​the rectifier plate 2 is divided into a middle area, a left edge area, and a right edge area. The ventilation holes 200 in the middle area of ​​the rectifier plate 2 are defined as first ventilation holes 210, and a plurality of first ventilation holes 210 are opposite to the first main air outlet 121. The ventilation holes 200 in the left edge area and the right edge area of ​​the rectifier plate 2 are defined as second ventilation holes 220, and a plurality of second ventilation holes 220 are opposite to the second main air outlet 122.

[0049] Optionally, the size of the first ventilation hole 210 is the same as the size of the second ventilation hole 220. When the size of the first ventilation hole 210 and the size of the second ventilation hole 220 are equal, a uniform air supply effect is achieved by adjusting the spacing between two adjacent first ventilation holes 210 and the spacing between two adjacent second ventilation holes 220. For example, the spacing between two adjacent first ventilation holes 210 is greater than the spacing between two adjacent second ventilation holes 220, so that the area of ​​the middle area of ​​the rectifier 2 that blocks air circulation is greater than the area of ​​the edge area that blocks air circulation. When the air reaches the middle area of ​​the rectifier 2, more air will flow to the two edge areas of the rectifier 2 with less resistance, so that the air flow in the middle of the downstream side of the rectifier 2 is close to that on both sides.

[0050] It can be understood that when the spacing between two adjacent first ventilation holes 210 and the spacing between two adjacent second ventilation holes 220 are equal, the width of the first ventilation hole 210 is smaller than the width of the second ventilation hole 220, so that the area of ​​the middle region of the rectifier plate 2 that blocks the air circulation is larger than the area of ​​the edge region that blocks the air circulation, and the uniform wind effect can also be achieved.

[0051] like Figure 1As shown, in an optional embodiment, the air outlet also includes a side air outlet 130 , the side air outlet 130 is provided on the third side wall 13 , or the side air outlet 130 is provided on the fourth side wall 14 , or both the third side wall 13 and the fourth side wall 14 are provided with side air outlet 130 .

[0052] For example, the third side wall 13 is provided with a side air outlet 130, and the number of the side air outlet 130 may be one or more. For example, the third side wall 13 is provided with two side air outlets 130, and the two side air outlets 130 are both located on a side of the third side wall 13 away from the first side wall 11, and the two side air outlets 130 are arranged at intervals along the height direction of the multi-chamber air distribution device, that is, one side air outlet 130 is close to the top wall, and the other side air outlet 130 is close to the bottom wall.

[0053] The side air outlet 130 can be connected to an air valve or an air duct to deliver air to corresponding rooms. The side air outlet 130 is arranged on the third side wall 13 and / or the fourth side wall 14 to deliver the air entering the multi-room air distribution device to more rooms to meet the air supply needs of multiple rooms.

[0054] In an optional embodiment, a first air outlet area and a second air outlet area are formed on the second side wall 12. The first air outlet area and the second air outlet area are arranged in sequence along a direction parallel to the height direction of the multi-chamber air distribution device. At least one main air outlet 120 is located in the first air outlet area, and at least one main air outlet 120 is located in the second air outlet area. A first ventilation area 21 and a second ventilation area 22 are formed on the rectifier plate 2. The first ventilation area 21 is arranged opposite to the first air outlet area, and the second ventilation area 22 is arranged opposite to the second air outlet area. The first ventilation area 21 and the second ventilation area 22 are respectively provided with a plurality of ventilation holes 200. Figure 2 The areas enclosed by the two dotted boxes are the first ventilation area 21 and the second ventilation area 22 respectively.

[0055] Specifically, according to the distribution of the main air outlets 120 in the width direction of the second side wall 12, the air outlet area on the second side wall 12 is divided into a first air outlet area and a second air outlet area, the first air outlet area is close to the top wall, the second air outlet area is close to the bottom wall, and the first air outlet area is located above the second air outlet area. Figure 1 As shown, one first main air outlet 121 and two second main air outlets 122 are distributed in the first air outlet area at intervals, and one first main air outlet 121 and two second main air outlets 122 are distributed in the second air outlet area at intervals.

[0056] like Figure 2As shown, according to the distribution mode of the ventilation holes 200 in the width direction of the rectifying plate 2, the ventilation area on the rectifying plate 2 is divided into a first ventilation area 21 and a second ventilation area 22, the first ventilation area 21 is close to the top wall, the second ventilation area 22 is close to the bottom wall, and the first ventilation area 21 is located above the second ventilation area 22. The first ventilation area 21 is opposite to the first air outlet area, and the second ventilation area 22 is opposite to the second air outlet area. A plurality of first ventilation holes 210 and a plurality of second ventilation holes 220 are arranged at intervals in the first ventilation area 21, and a plurality of first ventilation holes 210 and a plurality of second ventilation holes 220 are arranged at intervals in the second ventilation area 22.

[0057] The plurality of ventilation holes 200 are arranged in two rows and multiple columns, which not only achieves ventilation effect, but also helps to enhance the structural strength of the rectifier plate 2, prevents the rectifier plate 2 from deforming due to long-term impact of air flow, and ensures ventilation effect.

[0058] In this embodiment, the length of the ventilation holes 200 in the first ventilation area 21 is equal to the length of the ventilation holes 200 in the second ventilation area 22 .

[0059] In other embodiments, the length of the ventilation holes 200 in the first ventilation area 21 is not equal to the length of the ventilation holes 200 in the second ventilation area 22. For example, when the air entering the multi-chamber air distribution device from the main air inlet 110 is concentrated on the lower side of the main air inlet 110, or the main air inlet 110 is arranged at the lower part of the first side wall 11 of the housing 1, the length of the ventilation holes 200 in the first ventilation area 21 can be greater than the length of the ventilation holes 200 in the second ventilation area 22. That is, the length of the first ventilation hole 210 in the first ventilation area 21 is greater than the length of the first ventilation hole 210 in the second ventilation area 22, and the length of the second ventilation hole 220 in the first ventilation area 21 is greater than the length of the second ventilation hole 220 in the second ventilation area 22. This makes the area of ​​the second ventilation area 22 of the rectifier 2 that blocks the air flow greater than the area of ​​the first ventilation area 21 that blocks the air flow. When the air reaches the middle and lower area of ​​the rectifier 2, more air will flow to the first ventilation area 21 with less resistance, so that the air flow above and below the downstream side of the rectifier 2 is close, achieving a uniform wind effect.

[0060] The rectifying plate 2 is arranged on the downstream side of the main air inlet 110 and close to the side where the main air inlet 110 is located. That is, the distance L1 between the rectifying plate 2 and the first side wall 11 where the main air inlet 110 is located is smaller than the distance L2 between the rectifying plate 2 and the second side wall 12 where the main air outlet 120 is located. It is preferred that L2 is 6 to 7 times the length of L1. This ensures that after rectification, the air has enough space to flow, so that the wind flows smoothly to the main air outlet 120 and is discharged from the main air outlet 120, thereby avoiding the occurrence of turbulence.

[0061] The distance between the rectifying plate 2 and the main air inlet 110 is about 30 mm, which is the preferred installation position of the rectifying plate 2 .

[0062] Figure 3 It is a structural schematic diagram of a rectifier plate according to the second embodiment of the utility model.

[0063] Second embodiment

[0064] According to the distribution area of ​​the ventilation holes 200 on the rectifying plate 2, the second ventilation holes 220 include the second ventilation holes 220 located in the left edge area 23 of the rectifying plate 2 and the second ventilation holes 220 located in the right edge area 24 of the rectifying plate 2. The second ventilation holes 220 in the left edge area 23 are close to the third side wall 13, that is, the side where the side air outlet 130 is located. The second ventilation holes 220 in the right edge area 24 are close to the fourth side wall 14.

[0065] like Figure 3 As shown, Figure 3 The areas enclosed by the two dotted lines are the left edge area 23 and the right edge area 24 of the rectifier plate 2, respectively. The spacing between the two adjacent second vents 220 on the side close to the side air outlet 130 is smaller than the spacing between the two adjacent second vents 220 on the side away from the side air outlet 130. That is, the spacing between the two adjacent second vents 220 in the left edge area 23 is smaller than the spacing between the two adjacent second vents 220 in the right edge area 24, and the second vents 220 in the left edge area 23 are densely arranged than the second vents 220 in the right edge area 24. The remaining structure is the same as that of the first embodiment, and will not be repeated here.

[0066] like Figure 1 As shown, the multi-chamber air distribution device is also provided with two side air outlets 130 at the third side wall 13. When the air enters the multi-chamber air distribution device from the main air inlet 110, it contacts the rectifier plate 2 provided at the downstream side of the main air inlet 110. The spacing between the two second ventilation holes 220 in the left edge area 23 of the rectifier plate 2 is smaller than the spacing between the two second ventilation holes 220 in the right edge area 24, that is, the area of ​​the left edge area 23 of the rectifier plate 2 that blocks the air from the upstream side of the rectifier plate 2 to the downstream side of the rectifier plate 2 is smaller than the area of ​​the right edge area 24 of the rectifier plate 2 that blocks the air from the upstream side of the rectifier plate 2 to the downstream side of the rectifier plate 2. Therefore, when the air reaches the rectifier plate 2, more air will flow to the left edge area 23, so that more air will flow to the side air outlet 130, thereby avoiding that the air volume of the room connected to the side air outlet 130 is smaller than that of the room connected to the main air outlet 120.

[0067] In other embodiments, the spacing between the two second ventilation holes 220 in the left edge area 23 is equal to the spacing between the two second ventilation holes 220 in the right edge area 24, and the width of the second ventilation holes 220 in the left edge area 23 is greater than the width of the second ventilation holes 220 in the right edge area 24, which can also achieve a similar effect.

[0068] So far, the embodiments of the present invention have been described in detail in conjunction with the accompanying drawings. Based on the above description, those skilled in the art should have a clear understanding of the present invention.

[0069] It should be noted that the implementation methods not shown or described in the drawings or the text of the specification are all forms known to ordinary technicians in the relevant technical field and are not described in detail. In addition, the above definitions of each element are not limited to the various specific structures and shapes mentioned in the embodiments, and ordinary technicians in the field can simply change or replace them.
