Abstract

<P>PROBLEM TO BE SOLVED: To provide an air conditioner that allows easy mounting of a front panel, while preventing breaking of a mounting part, etc. <P>SOLUTION: An outer casing 1a which incorporates a compressor (not shown in the figure) and a fan comprises a bottom plate part 2, a front panel 4, a top plate part 5, and right and left side panel parts 3. The front panel 4 is formed of a metallic main plate part 10 and a resin front face part 9 secured to the main plate part 10. Engaged parts 8 are provided at the top and bottom of each side panel part 3. Engaging parts 11 for detachably engaging the engaged parts 8 are provided at the rear of the main plate part 10. Because the front panel 4 is fixed in horizontal and vertical positions by means of the engaging parts 11 and the engaged parts 8, the need to secure the lower portion of the front panel 4 to the bottom plate part 2 with screws or the like is eliminated. Because the engaging parts 11 are metallic, deformation or bending under stresses, as would occur with resin parts, will not occur. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to an air conditioner, and more particularly to a front panel mounting structure.

  A structure for attaching a front panel of a conventional outdoor unit of an air conditioner will be described with reference to FIGS.

8 and 9, the outer wall 1 a of the outdoor unit 1 of the air conditioner includes a bottom plate portion 2, left and right side plate portions 3 each having a notch portion 7 at the upper end, and resin-made protruding portions 6 at both upper ends. The front panel 4 includes a front panel 4 and a top panel 5. The front panel 4 is attached by engaging the protrusion 6 with a notch 7 formed in the side panel 3 and the lower end of the front panel 4 with a screw 4 a. Screwed to the front of the bottom plate 2. Then, the outer shell 1 is assembled by covering the top plate portion 5 with the engaging portion between the notch portion 7 of the side plate portion 3 and the projection portion 6 of the front panel 4 (see, for example, Patent Document 1).
JP-A-5-133563 (FIG. 1)

  However, in the configuration of the outer shell 1a of the conventional air conditioner, since the lower part of the front panel 4 is fixed to the bottom plate 2 with screws 4a, many man-hours are required for work during assembly and service. It was. Moreover, the projection part 6 formed in the upper left and right of the front panel 4 made of resin has a problem that it is easily deformed or broken by stress.

  Further, there is a problem that rattling occurs when the protrusion 6 of the front panel 4 is engaged with the notch 7 provided in the side plate 3.

  The present invention solves such a conventional problem, and an object thereof is to provide an air conditioner in which a front panel can be easily attached with a simple structure and has no rattling at an engaging portion. .

  In order to solve the above-described conventional problems, an air conditioner of the present invention has an outer shell incorporating a compressor and a blower fan, and the outer shell includes a bottom plate portion, a front panel, a top plate portion, and left and right plates. The front panel is composed of a main plate portion made of a metal plate and a resin front portion fixed to the main plate portion, and provided with engaged portions above and below the left and right side plate portions, An engagement portion that is detachably engaged with the engaged portion is provided at the rear portion of the main plate portion, and the front panel is fixed at the left and right, upper and lower positions by the engaging portion and the engaged portion. Therefore, it is not necessary to fix the lower part of the front panel to the bottom plate part with screws or the like, and the work during assembly and service is easy. Moreover, since the engaging part provided in the main board part is a metal, the deformation | transformation and bending by the stress which generate | occur | produce in a resin component do not generate | occur | produce.

  The air conditioner of the present invention has a simple configuration and is extremely easy to attach to the outer shell of the front panel. Further, since there is no rattling at the engaging portion, the rigidity of the outer shell is increased.

  1st invention has an outer shell which incorporates a compressor and a ventilation fan, The said outer shell is comprised from the baseplate part, the front panel, the top-plate part, and the left-and-right side-plate part, The said front panel is a metal plate. Formed by a main plate portion made of resin and a resin front portion fixed to the main plate portion, and provided with engaged portions on the upper and lower sides of the left and right side plate portions, and attached to and detached from the engaged portion at the rear of the main plate portion. The front panel is fixed at the left and right, top and bottom positions by the engaging section and the engaged section, so that the lower part of the front panel is screwed to the bottom plate. This eliminates the need for fixing with, and facilitates assembly and service work. Moreover, since the engaging part provided in the main board part is a metal, the deformation | transformation and bending by the stress which generate | occur | produce in a resin component do not generate | occur | produce.

  In the second invention, in particular, a flange portion is provided on the outer peripheral portion of the top plate portion of the first invention, and the outer periphery of the upper side portion of the front panel is held by the flange portion, and the front panel and the side plate portion are held by the flange portion. Is fixed, it is possible to close the engagement gap between the engaging portion and the engaged portion in the vertical and front-rear directions.

  In the third invention, in particular, the engaged portion of the first or second invention is formed in a vertically long hole shape, and the engaging portion is formed in at least one convex shape on both side portions of the main plate portion. The mating part is inserted into the engaged part and slid up and down to engage. The attachment of the front panel to the side plate part is simply inserted and slid into the engaged part. Therefore, it is extremely easy to attach and detach the front panel.

  In the fourth aspect of the invention, in particular, at least one of the main plate portion and the side plate portion of any one of the first to third aspects of the invention is formed with a protrusion for closing the engagement gap between the engagement portion and the engaged portion. Therefore, when the front panel is attached to the side plate portion, rattling between the engaging portion and the engaged portion does not occur due to the protruding portion, so that the rigidity as the outer shell of the air conditioner is increased and it is difficult to deform. Is.

  In the fifth aspect of the invention, in particular, a crease fold is formed below the engaged portion of any one of the first to third aspects, and the crease fold below the engaged portion is thicker than other portions. Therefore, when the front panel is attached to the side plate part, the gap between the engaging part and the engaged part is suppressed, rattling does not occur, and the rigidity of the outer wall of the air conditioner increases. It becomes difficult to deform.

  Embodiments of the present invention will be described below with reference to the drawings. Note that the present invention is not limited to the embodiments.
