Description

  The present invention relates to an air conditioner equipped with a lifting device that facilitates cleaning of a suction filter.

  Conventionally, in the maintenance of the suction filter of this type of air conditioner, several measures have been devised to eliminate the danger and trouble of going up to a stepladder and working at a high place (for example, see Patent Document 1).

  FIG. 8 shows a longitudinal sectional view of a conventional air conditioner described in Patent Document 1. As shown in FIG. FIG. 9 shows a detailed view of a wire reel fixing portion to the suction grill of a conventional air conditioner. FIG. 10 shows a cross-sectional view of a wire reel fixing portion to a suction grill of a conventional air conditioner. As shown in FIGS. 8, 9, and 10, a heat exchanger 3, a drain pan 4, a blower 5, a fan motor 6, and the like are disposed inside an indoor unit main body 2 embedded in the ceiling 1. A decorative panel 7 covering the lower opening is detachably attached to the main body 2. A suction port 8 is formed in the center of the decorative panel 7, and air outlets 9 are formed on both sides of the suction port 8. A suction grill 10 is fitted into the suction port 8, and a suction filter 11 is detachably locked behind the suction grill 10. A motor 13 capable of rotating in the forward and reverse directions is fixed to the bracket 12 attached to the inner wall of the decorative panel 7, and a reel 15 for winding the wire 14 is attached to the lower part of the motor 13. A wire tip fixing portion 16 for fixing the tip of the wire 14 in the bracket 12 is provided. A wire reel 17 is disposed on the suction grill 10 at a position almost directly below the reel 15 and the wire tip fixing portion 16, and the wire 14 is hooked on the wire reel 17 to suspend the suction grill 10. These devices are also arranged on the opposite side of the suction grill 10 and have a structure in which the suction grill 10 is suspended substantially horizontally.

  About the air conditioner provided with the raising / lowering apparatus comprised as mentioned above, the operation | movement is demonstrated below. When cleaning the suction filter 11, the motor 13 is rotated in the reverse direction. Then, when the wire 14 is rewound from the reel 15 and the suction grill 10 is lowered to a predetermined height in a substantially horizontal state, the motor 13 is stopped. In this state, an operator on the floor removes the suction filter 11 from the suction grill 10 and cleans it. When the cleaning is completed, the suction filter 11 is attached to the suction grill 10 again, and the reel 15 takes up the wire 14 by rotating the motor 13 forward. Then, when the suction grill 10 rises and reaches the suction grill storage portion 18 of the decorative panel 7, the motor 13 is stopped and the storage of the suction grill 10 is completed.

When the wire 14 is wound and unwound, the wire reel 17 rotates about the wire reel fixed shaft 18 in order to smoothly move the suction grill 10 up and down.
Japanese Patent Laid-Open No. 11-311423

However, in the conventional configuration, the wire reel 17 is rotated about the wire reel fixing shaft 18, so that the stopper 21 and the wire reel 17 for preventing the wire reel 17 from being detached from the wire reel fixing shaft 18 are provided in the suction grille. 10 has a problem that a large number of parts such as a wire reel fixing plate 19 and a wire reel fixing screw 20 for fixing to 10 are required.

  The present invention solves the above-described conventional problems, and includes an elevating device that can easily attach the wire to the suction grille without providing a large number of parts for fixing the wire reel to the suction grille. An object is to provide an air conditioner.

  In order to solve the above-described conventional problems, the air conditioner of the present invention is a wire guide for fixing a wire guide to a suction grill through a wire guide having a cross-sectional shape with good wire slidability on a wire of an elevating grill. A fixed plate is provided.

  As a result, it is not necessary to arrange a large number of parts on the suction grille, and it is possible to easily attach the wire to the suction grille, thereby providing an elevator grille that can be moved up and down smoothly and has good workability. it can.

  Moreover, the air conditioner of this invention provides the knob part for attachment or detachment to a wire guide. This makes it easy to attach and detach the wire guide, so that an elevating grill with good workability can be provided.

  In the air conditioner of the present invention, the suction grill and the wire guide fixing plate are integrally formed. This eliminates the need for the wire guide fixing plate and the screw for fixing the wire guide fixing plate, and therefore can provide an elevating grill that is inexpensive and requires less man-hours.

  In the air conditioner of the present invention, the wire can be easily and inexpensively attached to the suction grill, and a smooth lifting operation can be performed.

  In the first invention, one end of a wire is connected to each of a plurality of portions of a suction grill holding a suction filter, and a plurality of units provided on an interior unit body incorporating a heat exchanger, a blower, or the like or a decorative panel on the lower surface of the interior unit body In an air conditioner that can store the suction grille at the suction port of the decorative panel by winding the wire with a motor, the wire guide for fixing the suction grille is passed through the wire, and the wire guide is attached to the suction grille. By providing the wire guide fixing plate for fixing, it is not necessary to arrange a large number of parts for attaching the wire guide on the suction grille, and it is possible to provide an elevating grill that operates smoothly and inexpensively.

  In particular, in the air conditioner according to the first aspect of the present invention, the wire guide can be easily attached and detached by providing the wire guide with a knob portion for attaching and detaching from the wire guide fixing plate attached to the suction grille. Can be done.

  According to a third aspect of the invention, in particular, in the air conditioner of the first or second aspect of the invention, the wire guide fixing plate is integrally formed with the main body of the suction grill so that the wire guide fixing plate for attaching to the suction grill becomes unnecessary. An inexpensive lifting grill can be provided.
