Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of air conditioners, and in particular to an air outlet grille. Background Art
[0002] When the outdoor unit of the air conditioner is in operation, the wind enters from the condenser side, passes through the axial flow fan blades, and is blown out from the air outlet grille. The air outlet grille is provided with crisscross bars, which can not only ensure that the wind can be blown out smoothly, but also prevent the debris in the external environment from entering the outdoor unit housing.
[0003] However, the air outlet grilles in the prior art are prone to directly blow the wind onto passers-by, which gives people a very bad feeling. Utility Model Content
[0004] The utility model aims to provide an air outlet grille to solve the technical problem in the prior art that the wind blown out of the air outlet grille directly blows people.
[0005] The utility model provides an air outlet grille, comprising a frame and N first bars, where N is a natural number; the frame comprises a first frame and a second frame, the first bar is located between the first frame and the second frame, and the first frame, the first bar and the second frame are arranged at intervals along a first straight line direction;
[0006] The air outlet grille also includes a plurality of second bars, which are in the shape of curved flat bars, with both ends respectively fixedly connected between the first frame and its adjacent first bars, or between two adjacent first bars, or between the second frame and its adjacent first bars; along a second straight line direction perpendicular to the first straight line direction, a plurality of second bars are arranged at intervals, and of two adjacent second bars, one is bent forward and the other is bent backward.
[0007] The air outlet grille provided by the utility model can produce the following beneficial effects:
[0008] The air outlet grille provided by the utility model has a plurality of second bars arranged at intervals along the second straight line direction, and two adjacent second bars are bent forward and backward respectively, or in other words, the adjacent second bars are staggered forward and backward. Because the flat second bars 300 can well block the wind and change the wind direction, the second bars bent forward and the second bars bent backward can form an air outlet channel extending along the second straight line direction, and then the wind can be blown out along the second straight line direction, thereby avoiding the situation where the wind blows directly on people. In addition, the staggered arrangement of the plurality of second bars can not only prevent external debris from entering the outdoor unit housing from the front, but also prevent external debris from entering the outdoor unit housing from the side through the second bars bent forward and the wind blown out along the second straight line direction, and the protective function is better.
[0009] Furthermore, the second grid bar includes bent portions at two ends and a main body portion between the two bent portions, and the main body portion is parallel to the plane where the frame is located.
[0010] In this technical solution, the main body of the second grille protrudes forward or backward through the bent parts connected to its two ends. The main body is parallel to the plane where the frame is located, that is, roughly perpendicular to the air outlet direction, which can maximize the blocking effect of the second grille on the air outlet, so that the air outlet changes direction and blows out in the up and down direction.
[0011] Furthermore, the bending portion includes a first bending section, a second bending section and a third bending section connected in sequence, the first bending section is connected to the first frame, the first grid or the second frame, the third bending section is connected to the main body, and the second bending section is connected between the first bending section and the second bending section.
[0012] Under this technical solution, the cross-section of the air outlet grille along the length direction is roughly trapezoidal without a bottom, and the first bending section, the second bending section and the third bending section play the role of bending transition, so that the main body gradually reaches the designed target position.
[0013] Furthermore, the second grid bars are of symmetrical structure.
[0014] Under this technical solution, the second grille is more regular and beautiful, and the air outlet grille as a whole is also more regular and beautiful.
[0015] Furthermore, along the second straight line direction, the distance between two adjacent second grid bars is equal.
[0016] In this technical solution, the second grid bars are evenly arranged in the up-down direction, so it is possible to effectively avoid the situation where the air outlet channel formed by each column of the second grid bars 300 has excessive local air leakage.
[0017] Furthermore, at least one of the first bars is disposed between the first frame and the second frame; along the first straight line direction, one of two adjacent second bars is bent forward, and the other is bent backward.
[0018] Under this technical solution, a first grid bar is arranged between the first frame and the second frame, and the first grid bar and the first frame and the second frame can separate at least two spaces, and the second grid bar is arranged in each space. The first grid bar is connected to the second grid bar, which can support the second grid bar and improve the structural strength of the air outlet grille. Along the first straight line direction, the second grid bar is also staggered front and back, so that the air outlet grille has a larger blocking area to block debris on the left and right sides, has a better blocking effect on lateral debris, and is also more beautiful.
[0019] Furthermore, the first frame, the first grid bars, and the second frame are evenly arranged along the first straight line direction.
[0020] Under this technical solution, the distance between the first frame and the first bars adjacent to it, the distance between two adjacent first bars, and the distance between the second frame and the first bars adjacent to it are equal, so the size of the second bars along the left and right directions is consistent, the wind resistance at each part of the air outlet grille is more consistent, and the blocking effect on external debris is more uniform. In addition, the air outlet grille is also more regular and beautiful.
[0021] Furthermore, the frame also includes a third frame and a fourth frame, and the first frame, the third frame, the second frame and the fourth frame are connected end to end in sequence; one end of the first grid bar is fixedly connected to the third frame, and the other end is fixedly connected to the fourth frame.
[0022] Under this technical solution, the first frame, the third frame, the second frame and the fourth frame are connected end to end in sequence to form a rectangular frame, wherein the first frame and the second frame are connected to and support the respective adjacent second bars, and the third frame and the fourth frame are connected to and support the respective first bars.
[0023] Furthermore, the air outlet grille is an integrated structure.
[0024] Under this technical solution, the frame and each first grille and each second grille are an integrated structure, which can be made of plates through stamping and other processes. The process is simple, there is no need for assembly between the structures, and the integrity of the air outlet grille is also good.
[0025] Furthermore, the first straight line direction is a left-right direction, and the second straight line direction is an up-down direction.
[0026] Under this technical solution, when the outdoor unit of the air conditioner is in operation, the air outlet at the air outlet grille will be blown upward or downward, thereby avoiding blowing forward and directly blowing on people as much as possible.
[0027] Optionally, the first straight line direction is an up-down direction, and the second straight line direction is a left-right direction.
[0028] Under this technical solution, when the outdoor unit of the air conditioner is in operation, the air outlet from the air outlet grille will be blown to the left or right, and it can also avoid blowing forward and directly blowing on people as much as possible.

[0037] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific embodiments of the utility model are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0038] This embodiment provides an air outlet grille, such as Figures 1 to 3As shown, the air outlet grille includes a frame 100 and N first bars 200, N is a natural number, that is, N≥0 and N is an integer; the frame 100 includes a first frame 110 and a second frame 120, the first bar 200 is located between the first frame 110 and the second frame 120, and the first frame 110, the first bar 200 and the second frame 120 are arranged at intervals along a first straight line direction; the air outlet grille also includes a plurality of second bars 300, the second bars 300 are in the shape of curved flat bars, and both ends are fixedly connected between the first frame 110 and its adjacent first bars 200, or between two adjacent first bars 200, or between the second frame 120 and its adjacent first bars 200; along a second straight line direction perpendicular to the first straight line direction, the plurality of second bars 300 are arranged at intervals, and of the two adjacent second bars 300, one is bent forward and the other is bent backward.
[0039] The air outlet grille provided in this embodiment has a plurality of second bars 300 arranged at intervals along the second straight line direction, and two adjacent second bars 300 are bent forward and backward respectively, or in other words, the adjacent second bars 300 are staggered forward and backward. Because the flat second bars 300 can well block the wind and change the wind direction, the second bars 300 bent forward and backward can form an air outlet channel extending along the second straight line direction, and then the wind can be blown out along the second straight line direction, thereby avoiding the situation where the wind blows directly on people. In addition, the staggered arrangement of the plurality of second bars 300 can not only prevent external debris from entering the outdoor unit housing from the front, but also prevent external debris from entering the outdoor unit housing from the side through the second bars 300 bent forward and the wind blown out along the second straight line direction, and the protective function is better.
[0040] Specifically, in this embodiment, Figure 1 and Figure 2 As shown, the first straight line direction is the left-right direction, i.e., the direction indicated by arrows ab; the second straight line direction is the up-down direction, i.e., the direction indicated by arrows cd. Under this setting, when the outdoor unit of the air conditioner is running, the air at the air outlet grille will blow upward or downward, so as to avoid blowing forward and directly blowing on people.
[0041] Of course, in other embodiments of the present application, the first straight line direction may also be the up-down direction, and the second straight line direction may be the left-right direction. With this arrangement, when the outdoor unit of the air conditioner is in operation, the air at the air outlet grille will blow out to the left or right, and can also avoid blowing forward and directly blowing on people as much as possible.
[0042] Specifically, in this embodiment, Figure 1 and Figure 2As shown, five first bars 200 are arranged between the first frame 110 and the second frame 120, and six spaces are separated by the five first bars 200 and the first frame 110 and the second frame 120, and the second bars 300 are arranged in the six spaces. In this arrangement, the first bars 200 are connected to the second bars 300, which can support the second bars 300 and improve the structural strength of the air outlet grille.
[0043] Of course, in other embodiments of the present application, the number of the first grille 200 is not limited to five, but can be specifically set according to the size of the air outlet grille or other requirements, for example: three, four, six, etc., or can also be zero, that is, no first grille 200 is set.
[0044] Specifically, in this embodiment, Figure 1 and Figure 2 As shown, the first frame 110, the first grid bar 200, and the second frame 120 are evenly arranged along the first straight line direction, that is, the left-right direction. In this arrangement, the distance between the first frame 110 and the first grid bar 200 adjacent thereto, the distance between two adjacent first grid bars 200, and the distance between the second frame 120 and the first grid bar 200 adjacent thereto are equal, so the size of the second grid bar 300 along the left-right direction is consistent, the wind resistance at each part of the air outlet grille is more consistent, and the blocking effect on external debris is more uniform. In addition, the air outlet grille is also more regular and beautiful.
[0045] Specifically, in this embodiment, Figure 3 As shown, the second grid bar 300 includes a bent portion 310 at both ends and a main body 320 between the two bent portions 310, and the main body 320 is parallel to the plane where the frame 100 is located. In this arrangement, the main body 320 of the second grid bar 300 protrudes forward or backward through the bent portions 310 connected to its two ends. The main body 320 is parallel to the plane where the frame 100 is located, that is, roughly perpendicular to the air outlet direction, which can maximize the blocking effect of the second grid bar 300 on the air outlet, so that the air outlet changes direction and blows out in the up and down direction.
[0046] More specifically, in this embodiment, if Figure 3As shown, the bending portion 310 includes a first bending section 311, a second bending section 312 and a third bending section 313 connected in sequence, the first bending section 311 is connected to the first frame 110, the first grid bar 200 or the second frame 120, the third bending section 313 is connected to the main body 320, and the second bending section 312 is connected between the first bending section 311 and the second bending section 312. In this arrangement, the cross section of the air outlet grille along the length direction is roughly a trapezoid without a bottom, and the first bending section 311, the second bending section 312 and the third bending section 313 play a role of bending transition, so that the main body 320 gradually reaches the designed target position.
[0047] Specifically, in this embodiment, Figures 1 to 3 As shown, the second grid bar 300 is a symmetrical structure. With such arrangement, the second grid bar 300 is more regular and beautiful, and the air outlet grille as a whole is also more regular and beautiful.
[0048] Specifically, in this embodiment, along the second straight line direction, the distance between two adjacent second bars 300 is equal. In this arrangement, the second bars 300 are evenly arranged along the vertical direction, so that the situation of excessive air leakage in the air outlet channel formed by each row of second bars 300 can be effectively avoided.
[0049] Specifically, in this embodiment, along the first straight line direction, one of the two adjacent second bars 300 is bent forward and the other is bent backward. In this arrangement, the second bars 300 are not only staggered front and back in the up-down direction, but also staggered front and back in the left-right direction, so that the air outlet grille has a larger blocking area for debris on the left and right sides, has a better blocking effect on side debris, and is more beautiful.
[0050] Specifically, in this embodiment, Figure 1 and Figure 2 As shown, the frame 100 further includes a third frame 130 and a fourth frame 140, and the first frame 110, the third frame 130, the second frame 120 and the fourth frame 140 are connected end to end in sequence; one end of the first grid bar 200 is fixedly connected to the third frame 130, and the other end is fixedly connected to the fourth frame 140. More specifically, in this embodiment, the first frame 110, the third frame 130, the second frame 120 and the fourth frame 140 are connected end to end in sequence to form a rectangular frame, wherein the first frame 110 and the second frame 120 are connected to and support the respective adjacent second grid bars 300, and the third frame 130 and the fourth frame 140 are connected to and support the respective first grid bars 200.
[0051] Specifically, in this embodiment, the air outlet grille is an integrated structure, that is, the frame 100 and each first grille bar 200 and each second grille bar 300 are an integrated structure, which can be made of plates through stamping and other processes. The process is simple, there is no need to assemble the various structures, and the integrity of the air outlet grille is also good.
