In the prior art, the air guide scheme that the single driving part 60 is used for driving the push-out type air guide plate 20 causes the problems of large closed gap and poor sealing performance of the air guide plate 20, in order to solve the problems, the technical scheme of the application drives the first transmission component 30 and the second transmission component 40 which are respectively positioned at the left side and the right side through the single driving part 60 to realize the complete push-out of the air guide plate 20 of the air conditioner, and the initial phase difference of the first transmission component 30 and the second transmission component 40 at the two sides is set, so that the closed gaps at the two sides are uniform when the air guide plate 20 is closed, the cost is reduced, the energy is saved, and the uniformity and the good sealing performance when the air guide plate 20 is closed are ensured. By adopting the technical scheme of the application, the problems that the closed clearance of the air deflector 20 is large and the sealing performance of the indoor unit is poor due to the fact that the push-out type air deflector 20 is driven by the single driving part 60 are effectively solved.
Referring to fig. 1 to 14, according to an embodiment of the present application, an indoor unit is provided.
The indoor unit comprises a panel body 10, an air deflector 20, a first transmission assembly 30, a second transmission assembly 40 and a connecting rod 50. The panel body 10 has an air outlet 11. The air guide plate 20 is connected to the panel body 10. The air deflection plate 20 has an open position opening the outlet 11, and the air deflection plate 20 has a closed position closing the outlet 11. The first transmission assembly 30 comprises a first crank 31. The first transmission assembly 30 is connected to the air deflection plate 20. The second transmission assembly 40 comprises a second crank 41. The second transmission assembly 40 is connected with the air deflector 20. The first end of the connecting rod 50 is connected to the first crank 31. The second end of the connecting rod 50 is connected to the second crank 41. One of the first crank 31 and the second crank 41 is connected to the driving unit 60. A first connecting body is arranged at the connection position of the first crank 31 and the first end of the connecting rod 50. A second connecting body is arranged at the connection of the second crank 41 and the second end of the connecting rod 50. The first connecting body and the second connecting body are arranged with a phase difference therebetween, so as to reduce a gap between the air deflector 20 and the air outlet 11 when the air deflector 20 is located at the closed position.
By applying the technical scheme of the invention, one of the first crank 31 and the second crank 41 is connected with the driving part 60, the first connecting body is arranged at the joint of the first crank 31 and the first end of the connecting rod 50, the second connecting body is arranged at the joint of the second crank 41 and the second end of the connecting rod 50, and the first connecting body and the second connecting body are arranged in a phase difference manner, so that the gap between the air deflector 20 without the driving part side and the air outlet 11 in the closed state of the indoor unit with the air deflector 20 driven by the single-side driving part 60 can be compensated, the appearance of the indoor unit is more attractive, meanwhile, external foreign matters are effectively prevented from entering the interior of the indoor unit, and the service life of the indoor unit is effectively prolonged. By adopting the technical scheme of the application, the problem that a gap exists on one side of the air deflector 20 of the indoor unit adopting the single-side driving part 60 to drive the air deflector 20 is effectively solved.
Optionally, the first transmission assembly 30 and the second transmission assembly 40 are identical in structure. The connection form of one of the first transmission assembly 30 and the second transmission assembly 40 connected with the driving part 60 and the driving part 60 is as follows: an output shaft of the driving part 60 is connected with a reduction gearbox, and a power output shaft of the reduction gearbox is connected with one of the first crank 31 and the second crank 41.
As shown in fig. 6, 7, and 8, the shape of the cross section of the first connecting body is the same as the shape of the cross section of the second connecting body. The geometric center line at the first position of the cross section of the first connecting body and the geometric center line at the second position of the cross section of the second connecting body are arranged with a first included angle in the projection of the axial direction of the connecting rod 50. Wherein the first position is the same as the second position. Due to the arrangement, a preset initial phase difference exists between the first connecting body and the second connecting body, and therefore, as shown in fig. 11, a height difference value Δ Y is generated between the first transmission assembly 30 and the second transmission assembly 40 and the connecting end of the air deflector 20, so as to compensate for a gap of the air deflector 20 in the closed state.
In the present embodiment, the air guide plate 20 is driven by the one-side driving unit 60. To achieve a predetermined initial phase difference between the first and second connecting bodies, the deflection or offset should be performed on the non-driving side to which the driving portion 60 is not connected. As shown in fig. 7 and 8, for example, when the driving portion 60 is disposed at the rear side of the air deflector 20, the first mounting portion 51 connected to the rear side of the air deflector 20 is normally disposed, and the second mounting portion 53 connected to the non-driving side is disposed with a predetermined angle of deflection or offset.
Specifically, the first included angle is θ. Wherein, the theta is more than 6 degrees and less than 12 degrees.
Further, the first connection body includes a first mounting portion 51. The second connecting body includes a second mounting portion 53. The first end of the link 50 is provided with a first mounting portion 51. The second end of the link 50 is provided with a second mounting portion 53. The first mounting portion 51 has a first plane 511 and a second plane 512 symmetrically disposed along the axial direction of the link 50. The second mounting portion 53 has a third plane 531 and a fourth plane 532 symmetrically disposed in the axial direction of the link 50. The plane of the first plane 511 is arranged with a second angle to the plane of the third plane 531. The arrangement is such that the first and second mounting portions 51 and 53 can have good connection stability with the first and second transmission assemblies 30 and 40, respectively, and meanwhile, the first and second mounting portions 51 and 53 should be arranged in a special structure including, but not limited to, a flat shaft, a polygonal shaft, etc. so as to have a predetermined initial phase difference between the first and second connection bodies. If the first and second mounting portions 51 and 53 have a circular shaft structure, it is difficult to achieve the above object.
In this embodiment, the first connection body includes a first kidney-shaped hole 311. The second connector includes a second kidney-shaped hole 411. The first end of the first crank 31 is provided with a first kidney-shaped hole 311. The first end of the second crank 41 is provided with a second kidney-shaped hole 411. The projection of the geometric center line in the longitudinal direction of the first kidney-shaped hole 311 and the geometric center line in the longitudinal direction of the second kidney-shaped hole 411 in the axial direction of the link 50 has a third angle. The first ends of the first crank 31 and the second crank 41 should be provided with a special structure, including but not limited to a kidney-shaped hole, a polygonal hole, etc., so as to have a predetermined initial phase difference between the first connecting body and the second connecting body. If the first and second mounting portions 51 and 53 are formed as circular holes, it is difficult to achieve the above object.
It should be noted that, by offsetting one of the first mounting portion 51 and the second mounting portion 53 by the method in the above-mentioned embodiment and offsetting one of the first end of the first crank 31 and the first end of the second crank 41 by the method in the above-mentioned embodiment, a predetermined initial phase difference may be provided between the first connecting body and the second connecting body, and the two methods are substantially equivalent, but one method may be selected in engineering practice.
Further, the third angle is γ. Wherein, the Gamma is more than 6 degrees and less than 12 degrees.
Specifically, the derivation of θ and γ is as follows: fig. 12 shows a schematic diagram of the mechanical movement of the drive box assembly (the first transmission assembly 30 and the second transmission assembly 40) at a certain time, where BC is a crank (the crank includes the first crank 31 and the second crank 41), Δ CDE is a rocker (the rocker includes the first rocker 34 and the second rocker 44), CE is a length of the rocker, D is a movement point of the rocker on the guide rail 321, E is a position point of the rocker connected to the air deflector 20 in the movement process, E0 is a position point of the rocker connected to the air deflector 20 in the initial position (when the air deflector 20 is closed), and Δ Y is a height difference between the position E and the initial position point E0 when the rocker is connected to the air deflector 20 in a certain state. The following relationship is satisfied:
LAB cosα1+LAD cosα3＝LBC cosα2+LCD cosα4；
LAB sinα1+LAD sinα3＝LBC sinα2+LCD sinα4；
Y＝LBC sinα2-LCE sin(π/2-α5+α4)；
ΔY＝Y-Y0；
Δα2＝α2-α0；
where Y0 is the vertical height of the air deflection plate 20 at the initial position, i.e., point E when the air deflection plate 20 is closed. α 0 is an initial included angle Δ α 2 between the crank and the horizontal direction when the air deflector 20 is at the initial position, and is an angle (referred to as a crank rotation angle for short) by which the crank rotates relative to the initial position at the current position. By combining the above equations, a relationship curve between the crank rotation angle and Δ Y can be obtained by fitting. Fig. 14 shows the crank angle vs. ay for a dimensioned transmission assembly. The preset phase difference between the first connecting body and the second connecting body comprises a crank rotation angle.
When the air deflector 20 is in the closed state, the air deflector 20 is driven by the one-side driving portion 60, and when the torque is transmitted to the other side, the torque is attenuated, so that the other side of the air deflector 20 collapses. The wind deflector 20 on the yield side can be compensated by setting the initial angle difference between the two sides as shown in fig. 8 and 10, the yield is equivalent to Δ Y, the initial angle compensation amount (θ or γ) is equivalent to Δ α 2, and the actual yield can be solved by combining the above equations to obtain the initial angle difference Δ α 2 required to be set to compensate the yield.
