Definitions

  • the disclosure relates to an air conditioner indoor unit, in particular to a wall-mounted air conditioner indoor unit.
  • the air conditioner indoor unit generally comprises a panel body, a rear casing and a front panel connected with the panel body.
  • the chamber of the air conditioner is enclosed by the rear casing, the panel body and the front panel.
  • the left and the right side wall surfaces of the panel body are designed as a plane, so the indoor unit cannot be moved once by two hands due to no point of application of force on the sides of the main body when being conveyed or mounted, particularly when being placed on the floor, thereby being not easy to carry and move.
  • the useless space at the two side corners in the chamber of the indoor unit occupies a relatively large area, so that the whole volume of the air conditioner indoor unit is larger and the inner space is not utilized effectively.
  • the left and the right side walls and the top wall of the panel body of the air conditioner indoor unit are generally fixed and non-demountable. Due to the non-demountable left and right side walls of the panel body, the indoor unit cannot be cleaned effectively. Similarly, the top wall where the vent of the indoor unit is located is non-demountable, so that the vent cannot be demounted to be cleaned after the air conditioner is used for a long term. Accordingly, a lot of dust may be accumulated in the grilles of the vent to cause a sanitary hazard. Furthermore, the side walls and the top wall of the air conditioner are non-replaceable, so a common user cannot change the shape of the indoor unit nor update the casing once the indoor unit is mounted.
  • one objective of the disclosure is to provide an air conditioner indoor unit, which can be improved in the hand-holding effect and is convenient to carry and move.
  • Another objective of the disclosure is to provide an air conditioner indoor unit with demountable side walls so that a common user can demount the side walls of the air conditioner indoor unit without any tool.
  • the disclosure provides an air conditioner indoor unit, which comprises a panel body, a rear casing and a front panel connected with the panel body, wherein the chamber of the air conditioner indoor unit is enclosed by the rear casing, the panel body and the front panel; the panel body comprises a left side wall and a right side wall; and the outer surface of each of the left and the right side walls of the panel body is provided with an outward convex part or an inward concave part.
  • the disclosure further provides an air conditioner indoor unit, which comprises a panel body, a rear casing and a front panel connected with the panel body, wherein the chamber of the air conditioner indoor unit is enclosed by the rear casing, the panel body and the front panel;
  • the panel body comprises a left side wall and a right side wall;
  • the outer surface of left side wall of the panel body is provided with a left convex part which is convex outwards relative to the plane where the outer edge of the left side wall is located;
  • the outer surface of right side wall of the panel body is provided with a right convex part which is convex outward relative to the plane where the outer edge of the right side wall is located.
  • the air conditioner indoor unit is improved in the hand-holding effect and is convenient to carry and move.
  • the useless space at the corners in the chamber of the air conditioner is removed through the convex part and the concave part without changing the length and height, so as to utilize the inner space of the indoor unit more effectively.
  • the panel body further comprises at least one side wall connecting plate; and at least one of the left and the right side walls is connected with the at least one side wall connecting plate of the panel body in a demountable way.
  • the air conditioner indoor unit is easy to demount for cleaning.
  • a common user can replace the left and the right side walls according to their needs and likes to change the appearance of the air conditioner.
