Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to an air outlet correction structure and an air conditioner cabinet. Background Art

[0002] As people's living standards improve, cabinet air conditioners are becoming more and more common in households. Cabinet air conditioners generally adopt a split structure, consisting of an indoor unit and an outdoor unit, which are connected by pipes and wires.

[0003] The existing air-conditioning cabinet has an air outlet, on which an air guide assembly is arranged. The air guide assembly is relatively long and is prone to warping and deformation during the opening and closing process. At the same time, the length direction of the structure at the air outlet is too large, and if there is no support in the width direction, it is prone to deformation, which in turn affects the opening and closing of the air guide assembly. In addition, when the air guide assembly is opened, the damper motor rotates the air guide assembly to a certain position and stops, but the air guide assembly itself does not contact other structures, so that when the air guide assembly is opened and closed, the air guide assembly may still be pushed down by external force, causing the air guide assembly to lean back or forward excessively, so that the air outlet is not closed tightly.

[0004] The patent with authorization number CN205279375U mentions an air guide plate structure, which is provided with a rotating arm and a reinforcement. The rotating arm serves to open and close the air guide plate, and the reinforcement corrects the flatness of the air guide plate. The rotating arm and the reinforcement are arranged separately on the air guide plate, and the manufacturing and installation are relatively complicated.

[0005] It can be seen from this that it is necessary to invent a structure that can prevent the air guide component from warping and deforming, can correct the deformation in the length direction of the air guide component, and is easy to install. Summary of the invention

[0006] The problem solved by the present invention is that the air guide assembly and the air guide grid are warped and deformed in the length direction and the air outlet is not tightly closed.

[0007] In order to solve the above problems, the present invention provides an air outlet correction structure.

[0008] An air outlet correction structure includes a correction frame, the correction frame includes a first connecting arm and a second connecting arm, the first connecting arm and the second connecting arm are arranged to intersect at an angle, a correction end is provided on the first connecting arm or the second connecting arm, the correction end is rotatably connected to a rotating shaft on an air guide component through an open groove, and plays a supporting role in the length direction of the air guide component to prevent the air guide component from warping and deforming in the direction.

[0009] Furthermore, the air outlet correction structure also includes an air duct shell, which is provided with an air outlet, and the first connecting arm and the second connecting arm are mounted on both sides of the air outlet on the air duct shell, and the first connecting arm and the second connecting arm are both connected to both sides of the air outlet on one side, and are suspended in the air at the intersection, thereby supporting and correcting the air outlet of the air duct shell to prevent structural deformation at the air outlet and affect the opening and closing of the air guide door and the air guide plate.

[0010] The air guide assembly is provided with an air guide grille, which is fixedly connected to the air guide door. The air guide grille rotates to drive the air guide door to open and close. The air guide grille is used to allow air to pass through. The air can be swept left and right by rotating the air guide grille and the air guide door.

[0011] Furthermore, the inner groove of the open groove is cylindrical, and the opening is flared, which can be elastically connected to the rotating shaft of the air guide grille and enable the rotating shaft of the air guide grille to rotate in the groove.

[0012] The correction frame includes a first limiting portion and a second limiting portion. The first limiting portion is arranged on the first connecting arm and on the same side as the correction end. The first limiting portion limits the air guide assembly when the air guide door is closed. The second limiting portion is arranged on the second connecting arm and on the same side as the correction end. The second limiting portion limits the air guide assembly when the air guide door is opened to prevent loose closure and excessive opening.

[0013] The included angle between the first connecting arm and the second connecting arm is greater than 0° and less than 180°. Since the air guide grille is installed at the correction end and has an angle travel limit when it is rotated and opened, the included angle between the first connecting arm and the second connecting arm of the correction frame is set according to the opening angle of the air guide grille to ensure that the air guide grille can be rotated to the maximum angle.

[0014] The air guide grille includes a first rotating shaft, a second rotating shaft, and a third rotating shaft. The first rotating shaft and the third rotating shaft are arranged at both ends of the air guide grille and can be rotatably inserted into the connecting holes at both ends of the air duct shell. The second rotating shaft is arranged in the middle of the air guide grille and can be rotatably connected in the open groove at the correction end. The first rotating shaft plays a main supporting and guiding role, and the second rotating shaft is connected to the correction frame to play an auxiliary supporting and correction role.

[0015] Furthermore, the first rotating shaft, the third rotating shaft and the second rotating shaft of the air guide grille are coaxially arranged to ensure that the first rotating shaft, the third rotating shaft and the second rotating shaft rotate in the same direction.

[0016] Preferably, there is more than one correction frame, and the number of the second rotating shaft and the correction frame is the same. The correction frame and the second rotating shaft cooperate to correct the air guide grille. The air guide grille is relatively long, and multiple correction frames are provided to better maintain the flatness of the length direction of the air guide grille.

[0017] Compared with the prior art, the air outlet correction structure described in the present invention has the following advantages:

[0018] (1) The air outlet correction structure described in the present invention can correct the flatness of the air guide grille and the air guide door in the length direction to prevent the air guide door and the air guide grille from warping and deformation, and at the same time correct the air outlet of the air duct housing to ensure that the air guide door and the air guide grille can open and close normally;

[0019] (2) The air outlet correction structure described in the present invention is provided with a limit structure, which can limit the opening and closing of the air guide door;

[0020] (3) The air outlet correction structure described in the present invention is easy to install and disassemble.

[0021] Another object of the present invention is to provide an air conditioning cabinet, comprising the air outlet correction structure described above. BRIEF DESCRIPTION OF THE DRAWINGS
