Description

Technical Field

[0001] The utility model relates to the field of air conditioning equipment, in particular to an air outlet guide plate device. Background Art

[0002] The prior art swing blade static pressure box air outlet guide device includes a fan (i.e., impeller), a motor, a swing blade static pressure box, a vertical guide plate, and a horizontal swing blade bar. The air is pressurized by the fan and discharged from the swing blade static pressure box to the room, and the air supply direction is adjusted by the guide plate and the swing blade bar, thereby realizing the wind direction adjustment within a certain angle in the vertical direction.

[0003] However, when the fan cannot be placed in the center due to space limitations, for example, the fan is placed on the left, the wind speed at the static pressure box outlet is extremely uneven, and vortex dead zones may form in some areas. The wind speed is as low as 0.1m / s, and the wind speed difference at each position is as high as 11m / s. At the same time, in the vertical direction, the wind speed at the top is much higher than that in the middle and bottom, which brings a bad experience to customers. Utility Model Content

[0004] The main purpose of the utility model is to propose an air outlet guide plate device, which aims to solve the problem that the wind speed at the static pressure box outlet is uneven and eddy current zones may be formed in some areas when the fan cannot be placed centrally due to space limitations of the unit, so that the wind speed at each position of the static pressure box outlet is more uniform, avoiding customers' discomfort when blowing air, and making the fluid temperature more uniform.

[0005] In order to achieve the above object, the utility model provides an air outlet guide plate device, comprising:

[0006] The main body includes a front plate and a rear plate arranged at intervals, and a top plate arranged between the top of the front plate and the top of the rear plate,

[0007] The guide plates extend forward obliquely from both sides of the rear plate, and the guide plates include a first guide plate and a second guide plate, wherein the first guide plate and the second guide plate have different inclination angles.

[0008] The bottom end of the front plate and the bottom end of the rear plate form an air inlet, and the front plate is provided with an air outlet;

[0009] When the fluid is blown from bottom to top, the first guide vane and the second guide vane guide the fluid and direct the fluid toward the middle position of the static pressure box outlet.

[0010] In the actual design of the technical solution of the utility model, the main body is arranged in the static pressure box, wherein the front end of the static pressure box is provided with an outlet, and the air outlet of the main body is connected to the turbo fan, so that the fluid of the predetermined temperature can enter the static pressure box.

[0011] For example, when the main body is arranged at the first position close to the static pressure box, the first inclination angle between the first guide plate and the rear plate is smaller than the second inclination angle between the second guide plate and the rear plate, thereby directing the fluid toward the center position of the static pressure box outlet, avoiding the occurrence of a fluid blind spot, and achieving a consistent fluid flow rate at the static pressure box outlet.

[0021] like Figures 1 to 4 As shown, an air outlet guide plate device includes:

[0022] The main body includes a front plate 11 and a rear plate 12 which are spaced apart, and a top plate arranged between the top of the front plate 11 and the top of the rear plate 12.

[0023] The guide plates extend forward obliquely from both sides of the rear plate 12, and the guide plates include a first guide plate 21 and a second guide plate 22. The first guide plate 21 and the second guide plate 22 have different inclination angles.

[0024] The bottom end of the front plate 11 and the bottom end of the rear plate 12 form an air inlet 31, and the front plate 11 is provided with an air outlet 32;

[0025] When the fluid is blown from bottom to top, the first guide vane 21 and the second guide vane 22 guide the fluid toward the middle position of the outlet of the static pressure box 6 .

[0026] In the actual design, the main body is arranged in the static pressure box 6, wherein the front end of the static pressure box is provided with an outlet 61, and the air outlet 32 ​​of the main body is connected to the turbo fan (i.e., the blower), so that the fluid of the predetermined temperature enters the static pressure box 6.

[0027] For example, when the main body is arranged at the first position close to the static pressure box 6, the first inclination angle 201 between the first guide plate 21 and the rear plate 12 is smaller than the second inclination angle 202 between the second guide plate 22 and the rear plate 12, thereby directing the fluid toward the center position of the outlet of the static pressure box 6, avoiding the occurrence of a fluid blind spot, and thus achieving a consistent fluid flow rate at the outlet of the static pressure box 6.

[0028] Specifically, a first inclination angle 201 is provided between the first guide plate 21 and the rear plate 12 , and a second inclination angle 202 is provided between the second guide plate 22 and the rear plate 12 .

[0029] More specifically, the guide vane is inclined outward from the rear plate 12, that is, a bird-wing-type guide vane is formed. It is worth noting that the first guide vane 21 is at an angle of 60° with the vertical direction, so that most of the first exhaust air is first shot into the static pressure box 6, mixed for a period of time, and then discharged from the unit. The second guide vane 22 is at an angle of 45° with the vertical direction, wherein the actual inclination angle can also be adjusted according to actual needs, so that most of the exhaust air flowing out from the right side is guided by the second guide vane 22 and directly shot to the right side outlet of the static pressure box 6, so that more air volume flows to the right side, avoiding the formation of the vortex dead zone on the right side, increasing the air outlet speed on the right side, and making the overall air supply speed more uniform.

[0030] In the embodiment of the utility model, a bending plate 4 is provided between the rear plate 12 and the top plate, and the inclination angle of the bending plate 4 is 45 degrees. Through the arrangement of the top plate, the static pressure bellows can withstand a greater wind pressure, while reducing the attenuation of the wind speed. At the same time, the arrangement of the bending plate 4 allows the fan exhaust to be discharged forward, so that it does not all rush to the top of the static pressure box 6, so that the wind speed above the static pressure box 6 is reduced, and the noise is also reduced.

[0031] Specifically, the top plate is provided with ventilation holes 5 arranged at intervals, that is, the arrangement of the ventilation holes 5 increases the upward resistance of the fluid and reduces the wind volume and wind speed in the upward direction, so that the wind speed above the static pressure box 6 is reduced, so that most of the exhaust air is discharged forward, left and right;

[0032] There is no sheet metal blocking the front of the front plate 11, so the exhaust air can be discharged smoothly forward;

[0033] In the embodiment of the present invention, the first inclination angle 201 is 45 degrees, and the second inclination angle 202 is 60 degrees.

[0034] In the embodiment of the utility model, the main body is arranged in the static pressure box 6, the static pressure box is provided with an outlet, and the outlet is provided with a vertical swing leaf 61, which further improves the guidance of the fluid. Figure 4 As shown, before the improvement, no guide plate is set or the guide plate is set in the center; after the improvement, the test data is set with a guide plate, which includes three groups of embodiments, among which left 1 is 601, left 2 is 602, right 3 is 603, and left 4 is 604.

[0035] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
