  • As shown in figure 1, the wall mounted air conditioner of the present application includes a panel 1. An air outlet 10 is provided in the panel 1, and a swing blade mechanism 3 is provided at a lower portion 102 of the air outlet.
  • In the prior art, the swing device for is generally mounted at the upper portion 101 of the air outlet 10. However, since the air outlet has a larger air output at the lower portion 102 than at the upper portion, it is difficult for the swing device located at the upper portion of the air outlet 10 to perform an effective sweep for the air outgoing from the lower portion 102 of the air outlet, and the air discharging angle of the air conditioner is also limited. In the present application, the swing blade mechanism 3 is provided at the lower portion 102 of the air outlet, which can efficiently change the air discharging direction, and can improve the air discharging angle under a relatively large air force, thereby increasing the flowing range of the air discharged from the air conditioner indoors and increase the comfortable feeling of the people.
  • As shown in figures 2 and 3, in order that the swing blade mechanism 3 can achieve a better swing angle and can be detached or mounted flexibly, preferably, the swing blade mechanism 3 may include a base 31, a transmission mechanism 33, and a plurality of swing blades 35 connected in a transmission manner to the transmission mechanism 33. An end of the transmission mechanism 33 is connected in a transmission manner to a drive output end of a swing motor of the wall mounted air conditioner. The swing blades 35 can be driven to swing left or right under the drive of the swing motor. The plurality of swing blades 35 may be provided on the base 31 in sequence and at an equal interval.

The blade seat 353 is fixedly connected to an air outlet seat of the lower portion 102 of the air outlet 10.
  • In order that the swing blade 35 can be easily deformed to better change the air guide angle, such that the blade body 351 may swing at a larger angle and the swing resistance may be reduced, the elastic connecting part 355 may be of an elongated shape, and an upper end of the elastic connecting part 355 may be connected to an inner edge of the blade body 351.
  • Preferably, in the present embodiment, the upper end of the elastic connecting part 355 may be connected to an upper end of the inner edge of the blade body 351, to efficiently reduce the connection portion between the elastic connecting part 355 and the blade body 351 and increase the swing flexibility of the blade body 351.
  • The blade body 351 may be fixedly connected to the base 31 via the elastic connecting part 355 and the blade seat 353. The elastic connecting part 355 and the blade body 351 may be made into one piece, or be formed separately. The elastic connecting part 355 and the blade seat 353 may be made into one piece, or be formed separately. The blade seat 353 may be fixedly connected to the base 31 in an inserted coupling manner, and accordingly, the base 31 may be provided with the corresponding number of grooves. Generally, the blade body 351 may be made of an elastic material that can be bent, such that the blade body 351 can be driven by the transmission mechanism 33 to swing left of right under the elastic force.

  • The blade notch 352 may be provided at a middle portion of an outer edge of each blade body 351 and is located at the opposite side of the elastic connecting part 355.
  • When the swing blade mechanism 3 is operated, the connecting rod is rotated under the drive of the drive output end of the swing motor, and thus drives the blade body 351 of each swing blade 35 to swing left or right so as to perform the air sweep, thereby achieving the adjustment of a relatively large air discharging angle.
  • As shown in figure 4, in order to further facilitate the adjustment of the swing angle of the swing blades 35, and also to avoid the circumstance in which the direction of the air can not be adjusted due to the breakdown of the swing motor, the swing blade mechanism 3 may further includes a manual adjusting device.

  • The manual force exerting portion 321 may also be configured as a handle mounted on the rotary shaft 32. The rotary shaft 32 may be rotated at an angle by operating the handle, such that the connecting rod moves by a distance in a longitudinal direction, thereby achieving the adjustment of the air direction via the swing blades 35 connected to the connecting rod.
  • In order that the swing blade mechanism 3 can be stably mounted on the air outlet seat of the lower portion 102 of the air outlet 10 and can be easily detached, preferably, the swing blade mechanism 3 may further include a sinking step portion 37 which is at least provided at a longitudinal edge portion of the base 31. A lower side of the sinking step portion 37 may be detachably fixed on the air outlet seat of the lower portion of the air outlet 10.

Accordingly, two protrusions corresponding to the two middle counter bores 381 may be provided at corresponding positions of the air outlet seat of the lower portion 102 of the air outlet 10.
  • The rectangular recesses 38 may also be of a circular shape or any other suitable shape.
  • When the swing blade mechanism 3 is to be mounted in whole to the lower portion 102 of the air outlet 10 of the wall mounted air conditioner according to the present application, the protrusions on the air outlet seat of the lower portion 102 of the air outlet 10 may be inserted into the edge counter bores 382, thereby achieving the reliable mounting of the swing blade mechanism 3. With this kind of mounting structure, when the swing blade mechanism 3 is failure or needs to be cleaned, the swing blade mechanism 3 may be easily detached from the wall mounted air conditioner, which is convenient and flexible.
  • The above embodiments are merely preferred embodiments of the present application, and are not intended to limit the invention. Those skilled in the art may also make many alterations and modifications to the present application. Any modifications, equivalents or improvements without departing from the spirit and principle of the present application should be deemed to fall into the protection scope of the present application.
