Referring to fig. 2, the air guiding grille is an air guiding device installed at an air inlet or an air outlet, and generally includes an installation frame and a plurality of grille strips, wherein the plurality of grille strips are uniformly installed on the installation frame.
In embodiment 1, fig. 2 to 6 are specific embodiments of an air guide grid according to an embodiment of the present invention, where the air guide grid 1 in this embodiment includes an installation frame 11, and a plurality of grid bars 12 disposed on the installation frame 11, one side edge of the grid bar 12 along an air guide direction is connected with an air deflector 13, the air deflector 13 extends out of a plane where the installation frame 11 is located, and the grid bar 12 and the air deflector 13 are inclined toward a same side perpendicular to the plane where the installation frame 11 is located.
According to the air guide grid 1 provided by the embodiment of the invention, as the air guide plate 13 is connected to one side edge of the grid strip 12 along the air guide direction, the air guide plate 13 extends out of the plane of the mounting frame 11, and the grid strip 12 and the air guide plate 13 are inclined towards the same side perpendicular to the plane of the mounting frame 11, when the air guide grid 1 is mounted at the air inlet of the air conditioner and the air guide plate 13 is positioned in the air conditioner, the fan in the air conditioner can suck the outside air into the air conditioner and send the outside air into the air conditioner, so that negative pressure is formed in the air duct, the outside air can enter the air conditioner along the inclined grid strip 12 and the air guide plate 13, the wind field near the air inlet is stable, a stable high-low pressure area can be formed, and the air is not easy to form turbulent eddies outside the air inlet, therefore, the air guide grid provided by the embodiment of the invention reduces the wind resistance at the air inlet and reduces.
Alternatively, the inclination of the grate bars 12 and the air deflectors 13 may be the same or different. In addition to the above embodiments, referring to fig. 7 to 8, in the air guiding grille 1 of the embodiment of the present invention, the first bending portion 121 is disposed at one end of the grille strip 12 connected to the air guiding plate 13, the first bending portion 121 is bent toward the first direction P, and the connection between the grille strip 12 and the air guiding plate 13 is gentle, so as to reduce the resistance to air.
Similarly, referring to fig. 8, the end of the grid bar 12 away from the air deflector 13 is provided with a second bending portion 122, wherein the second bending portion 122 is bent toward a second direction M, the second direction M is opposite to the first direction P, that is, the bending directions of the second bending portion 122 and the first bending portion 121 are opposite, so as to reduce the resistance of the grid bar 12 to the air, improve the wind resistance of the grid bar 12, and reduce the aerodynamic noise.
Based on the above embodiments, the first bending part 121 and the second bending part 122 of the grid bar 12 in the embodiment of the present invention are both provided with the rounded corners 123, as shown in fig. 8, so as to further reduce the resistance of the grid bar 12 to the air, so that when the air flows between the grid bars 12, the speed is faster, and the air speed in each area of the air inlet is more uniform and more stable.
Alternatively, the air guiding plate 13 may have a flat plate structure or an arc plate structure. Preferably, the air deflector 13 in the embodiment of the present invention is a circular arc plate structure, as shown in fig. 7. When the air conditioner is applied to the air conditioner, when the air flows along the arc surface of the air deflector 13, the flow speed of the air is increased, the pressure is reduced, and local low pressure is caused on the lower surface of the air deflector 13, so that the air inlet direction of the air flows to the upper part of the air conditioner along the air inlet, and the air inlet efficiency of the air conditioner is improved. Specifically, the air deflector 13 and the grid bars 12 are integrally formed.
Further, if the included angle α between the extending surface of the end of the grid bar 12 connected to the air deflector 13 and the plane of the mounting frame 11 is greater than 30 °, the bending angle of the first bending part 121 is reduced under the same air inlet area condition, so that the die drawing is difficult, and the processing cost of the air guide grid 1 is increased; if the included angle alpha between the extending surface of the end of the grid bar 12 connected with the air deflector 13 and the plane where the mounting frame 11 is located is less than 20 degrees, the number of the grid bars which can be mounted is reduced in the air inlets with the same size, namely the air inlet area of the air inlets is reduced, so that the air inlet volume of the air conditioner is reduced. Therefore, in the embodiment of the present invention, the included angle α preferably ranges from 20 ° to 30 °, as shown in fig. 7.
Based on the angle selection of the included angle α between the extending surface of the end of the grid bar 12 connected to the air deflector 13 and the plane of the mounting frame 11, the included angle β of the first bending part 121 in the embodiment of the present invention ranges from 90 ° to 110 °, as shown in fig. 7 to 9, if the included angle β of the first bending part 121 is greater than 110 °, in the air inlets of the same size, the number of grid bars that can be mounted is reduced, that is, the air inlet area is reduced, and the air inlet volume of the air conditioner is smaller; if the included angle β of the first bending portion 121 is smaller than 90 °, the processing difficulty of the grid bars 12 and the air deflectors 13 is increased, and the processing cost is increased. The air guide grid 1 of the embodiment of the invention can be used for not only an air conditioner but also air purification equipment, and the air guide grid 1 has the same function.
The embodiment of the present invention further includes an air conditioner 100, which includes a casing 101, an air inlet 110 and an air outlet are formed in the casing 101, the air guide grille 1 described in the above embodiments is installed at the air inlet 110, and an air deflector 13 in the air guide grille 1 is located in the air conditioner 100, as shown in fig. 10. Since the air guide grille installed in the air conditioner 100 of the present embodiment has the same structure as that provided in each of the embodiments of the air guide grille 1 described above, both can solve the same technical problems and achieve the same intended effects.
The air conditioner 100 of the embodiment of the invention can be a vertical air conditioner, the distance between the lower surface of the shell 101 of the air conditioner 100 and the ground is 15-20 mm, the size is small, and the air conditioner is convenient to use. Specifically, a positioning block 14 is arranged at the lower edge of an installation frame 11 in the air guide grille 1, a fixing hook 15 is arranged at the upper edge of the installation frame 11, the air guide grille 1 is positioned with the air conditioner 100 through the positioning block 14, and then the air guide grille 1 is fixed at an air inlet 110 of the air conditioner 100 through the fixing hook 15.
Because the air conditioner 100 in the embodiment of the present invention is placed on the ground, in order to avoid users from seeing the internal structure (such as a fan, an air guiding ring, etc.) of the air conditioner 100 through the gap between the air guiding grilles, preferably, the air inlet 110 in the embodiment of the present invention is located on the side plate of the casing 101, and the air guiding plate 13 is located above the grille bar 12 connected thereto, that is, the air guiding plate 13 is directed upwards, so that the appearance of the air conditioner is more beautiful, and when air enters, dust is easily accumulated on the upper surface of the grille bar 12, and the dust cleaning operation on the upper surface of the grille bar 12 is easier. Specifically, in the embodiment of the present invention, a backward-inclined centrifugal fan is installed in the air conditioner 100.
For some vertical air conditioners, the air outlet and the air inlet are arranged on the same panel of the shell, and the distance between the air inlet and the air outlet is short. If the distance L between the air outlet and the air inlet 110 is greater than 8cm, the installation positions of other parts of the panel of the air conditioner may be affected, for example, the area of the display area of the panel may be affected; if the distance L between the air outlet and the air inlet 110 is less than 4cm, the wind field at the lower side of the air inlet 110 and near the upper side of the air outlet is relatively disordered, and the problem of serious return air short circuit can occur, so that preferably, the value range of the distance L between the upper edge of the air outlet and the lower edge of the air inlet 110 is 4-8 cm, the air conditioner 100 can be ensured to be small in size, and the problem of return air short circuit is reduced.
Alternatively, the air outlet of the air conditioner 100 may be disposed on the top plate 1011 of the housing 101, or may be disposed on a side plate of the housing 101. In consideration of the fact that the hot air flows upwards and the cold air flows downwards, preferably, the air outlet of the embodiment of the present invention includes a first air outlet 120 and a second air outlet 130, wherein the first air outlet 120 and the air inlet 110 are located on the same side plate of the housing, and the first air outlet 120 is located below the air inlet 110, so that the first air outlet 120 is used for outputting the hot air, which can make the air conditioner 100 have a better heating effect near the ground; the second air outlet 130 is located on the top plate 1011 of the housing 101 and is used for discharging cold air, so that the air conditioner 100 has a better cooling effect for each indoor area.
Further, for a vertical air conditioner that is placed on the ground and has a small volume, the length of the front panel 1012 is usually greater than the length of the side panel (i.e., the width of the air conditioner in fig. 10), so in the embodiment of the present invention, both the first air outlet 120 and the air inlet 110 are located on the front panel 1012 of the housing, and for the convenience of viewing by a user, the upper portion of the front panel 1012 is used for installing a display device, that is, both the first air outlet 120 and the air inlet 110 are located on the lower portion of the front panel 1012 of the housing 101, and the range of the distance between the first air outlet 120 and the air inlet 110 is controlled to be 4-.
A test platform is built, and each parameter of the air guide grid 1 is as follows: the length L1 of the part of the air deflector 13, which is located outside the plane of the mounting frame 11, is 6mm, the width L2 of the mounting frame 11 is 7-10 mm, the thickness H of the grid bar 12 is 2-3 mm, the included angle alpha between the extending surface of the end, connected with the air deflector 13, of the grid bar 12 and the plane of the mounting frame 11 is 20 degrees, the included angle beta of the first bending part 121 is 100 degrees, the radius R1, which is far away from the end of the grid bar 12, of the air deflector 13 is 1mm, the radius R2 of the air deflector 13 is 30mm, the air guide grid 1 with the parameters is installed at the air inlet 110 of the air conditioner 100, the air guide grid 1 is upwards air guide, and experiments and simulation calculation show that the air guide grid 1 of the embodiment of the invention can reduce the problem of the return air at the position where the air inlet 110 faces 10cm outwards and the upper edge of the first air outlet 120 faces 4cm upwards.
