  • the air deflector is provided here, it is only to show positions of air outlets of left and right air sweeping mechanisms of the present embodiment inside the air deflector, and both do not have a technical problem of mutual interference in operation, reference to a sectional view of the main body assembled while the air deflector and the left and right air sweeping mechanisms are at an extreme position as shown in Fig. 18 for details.
  • a structure feature of the present embodiment is a position, adjacent to the interior, positioned at the air outlet, namely a position, adjacent to the inside, of the air deflector and left and right air sweeping blades fixed on the air duct part and a related gear driving mechanism thereof.
  • a core part (a structure which achieves the left and right air sweeping by using a gear transmission mechanism) of the present application is described in detail below.
  • the overall left and right air sweeping blades include: air sweeping blades, a connecting rod, a driven gear, connecting rod end heads, positioning bulges and connecting rod smooth sections.
  • shaft sleeves with opens made of a POM material, having lubrication and abrasion-proof effects in movement, and preventing an abnormal noise
  • the shaft sleeves are in clearance fit with the a shaft, the rotated shaft in transmission is protected better
  • the outlet air frame part may be assembled while the whole transmission mechanism is assembled completely, an edge of the air outlet of the outlet air frame part is aligned to a bottom housing air outlet of the air duct part, the left and right installing
  • Middle portions of the connecting rod are provided with two sections of the cylinder cooperated smooth sections, the smooth sections are respectively clamped in a middle supporting groove, designed between upper and lower edges of the air outlet, in the air duct part, have a supporting effect to the air sweeping blade connecting rod, and prevent the middle thereof from sagging.
  • the overall left and right air sweeping driving gear includes: a transmission end head with a left end part hexagonal prism, an input shaft left end clamping port, an input shaft left end clamping port pressing arm, an input shaft positioning bulge, a driving gear and an input shaft main body shaft section.
  • the transmission end head with the hexagonal prism When assembling, the transmission end head with the hexagonal prism is inserted and connected in the output shaft of the left and right air sweeping driving motor, the input shaft left end clamping port pressing arm is pinched at the same time during the assembly so that the input shaft left end clamping port is opened to clamp the exterior of the motor output shaft and cooperated with a step of a right end of the motor output shaft, so as to prevent an inserting end from being disconnected; a smooth circular shaft section is between the driving gear and the positioning bulge, and equipped with a shaft sleeve with an open, and then it is clamped in position from an opening of a big gear shaft installing groove at a left side of the bottom housing, and assembled inside the installing groove.
  • gear meshing transmission analyzed in Fig.
  • a groove wall here may also apply a restrictive limitation force (F limitation 1 marked in Fig. 15 and F limitation 2 marked in Fig. 19 ) to the shaft, so as to ensure that the shaft may not be disconnected.
  • a gear transmission portion (including the air sweeping blades) of the transmission mechanism is pre-assembled inside the air duct part, to form the air duct part together.
  • the input shaft (namely the left end part hexagonal prism end head of the driving gear) of the left and right air sweeping driving gear is butted to the motor output shaft of the left and right air sweeping motor driving assembly fixed on the substrate, so as to achieve the transmission from left to right.
  • the specific transmission may be analyzed according to Fig. 6 , the core left and right air sweeping mechanism is assembled in the air duct part fixed on the substrate part, and fixed in a middle position of the air outlet of the bottom housing part.
  • a main body movement part in the left and right air sweeping mechanism includes: a left and right air sweeping driving motor output shaft, a left and right air sweeping driving gear body, and a left and right air sweeping blade body. It may be observed in combination with Fig.
  • the overall transmission mechanism is rotated by the motor output shaft of the left and right air sweeping motor driving assembly at the left side, rotation output drives an input shaft of the left and right air sweeping driving gear, thereby an integrated left and right air sweeping gear transmission mechanism driving gear is driven, the rotation is transmitted to a left and right air sweeping gear transmission mechanism driven gear positioned at a left end portion of the left and right air sweeping blade part by a meshing transmission effect of the gear transmission, the driven gear and the air sweeping blades are integrally injection-formed, driven gear rotation brought by the transmission may drive the entire air sweeping blade part to rotate, and an included angle between a plane (an angle in 45 degrees is formed between the air sweeping blades designed in this structure and a main body rotation axis) that has a certain designed angle already and the draft direction is changed, thereby the effect of changing a movement direction of the outlet airflow is achieved, and left and right adjustment of the wind direction is realized.
  • a plane an angle in 45 degrees is formed between the air sweeping blades designed in this structure and
  • Such a design flexibly realizes the separation of the left and right air sweeping motor from the air duct part and the outlet air frame part which need to be disassembled and cleaned, and it is also guaranteed that the automatic left and right air sweeping is realized.
  • the reason that direct transmission of an air sweeping motor output shaft and the air sweeping blade rotating shaft is not used, but it is transmitted by a driving big gear, is to achieve off-axis transmission, and avoid an interference problem (analyzed by Fig. 12 and Fig. 20 , the air sweeping blade transmission shaft and the leftwards and rightwards symmetrical dranpipes are consistent in space position, once the air sweeping blade transmission shaft is straight-through directly transmitted, the interference may exist inevitably) of left and right drainpipes and an air sweeping blade transmission shaft.
  • the air conditioner of the present application has the following advantages.
  • the present application mainly solves problems that a left and right air sweeping structure of an existing wall-hanging air conditioner is complicated and unstable, the wind resistance is too larger, and the noise is too high.
  • a structure form of left and right air sweeping is simplified, air sweeping efficiency and assembling efficiency of the mechanism are improved, and the wind resistance and the noise are reduced.
  • the adaptability of the left and right air sweeping structure is improved too, it conveniently realizes a structure design of the left and right air sweeping under more complicated space conditions, and a technical problem, encountered in this time of developing an easy-disassembled modular air conditioner, that it is difficult to separate the left and right air sweeping motor from a cleaning main body module is directly solved.
  • orientation or position relationships indicated by orientation words such as “front, back, up, down, left, right", “transverse, vertical, perpendicular, horizontal” and “top, bottom” are usually based on the orientation or position relationships shown in the drawings, it is just for conveniently describing the present application and simplifying the description, in the case without contrary statement, these orientation words do not indicate and imply that devices or elements referred must have a specific orientation or be constructed and operated in the specific orientation, therefore it may not be understood as the limitation to a scope of protection of the present invention; and the orientation words “inside and outside” refer to the inside and outside relative to an outline of each part itself.
  • spatial relative terms such as “over”, “above”, “on an upper surface” and “upper” may be used herein for describing a spatial position relation between a device or feature and other devices or features shown in the drawings. It will be appreciated that the spatial relative terms aim to contain different orientations in usage or operation besides the orientations of the devices described in the drawings. For example, if the devices in the drawings are inverted, devices described as “above other devices or structures” or “over other devices or structures” will be located as “below other devices or structures” or “under other devices or structures”. Thus, an exemplar term “above” may include two orientations namely “above” and “below”. The device may be located in other different modes (rotated by 90 degrees or located in other orientations), and spatial relative descriptions used herein are correspondingly explained.
