Description

  The present invention relates to an air conditioner, and more particularly to an air conditioner equipped with an air purifier.

  A conventional air conditioner with an air cleaner will be described with reference to FIG.

  In FIG. 8, 18 is an indoor unit of an air conditioner, 13 is a frame that forms the exterior of the indoor unit 18, 14 is a detection unit that determines whether a switch (not shown) of the air purifier 19 is on or off, 15 Is a front frame constituting a part of the exterior of the indoor unit 10, 16 is a suction grille constituting the exterior, and 16 a is a protrusion provided on the suction grill 16.

With the above configuration, the projection 16a provided on the suction grill 16 with the detection unit 14 attached to the special tool 17 turns the suction grill 16 to turn on and off the switch of the air cleaner 19, and the detection unit 14 Was operating (see, for example, Patent Document 1).
JP-A-10-274421

  However, in the above-described conventional configuration, the protrusion 16a provided on the suction grille 16 for operating the switch of the air cleaner 19 is a hole necessary for operating the switch of the air cleaner 19 provided on the front frame 15. When the product drop test is performed to assure quality during transportation of the air conditioner, the projection 16a provided on the suction grill 16 is damaged by colliding with the hole 15a provided on the front frame 15 Had the problem of doing.

  In addition, there is a problem that there is no positioning in the horizontal direction and vertical direction of the suction grill 16 and the front frame 15, and variation in the operation direction of the detection unit 14 occurs greatly. Furthermore, when the air conditioner 19 is provided in the air conditioner, either the left or right of the air filter is large, and both ends of the larger air filter are lifted.

  The present invention solves the above-described conventional problems, and prevents a protrusion that operates a detection unit that determines whether an air cleaner is turned on or off from being damaged during transportation, and prevents dust from entering due to warping of the air filter. It aims at providing the air conditioner which prevents.

In order to solve the above-described conventional problems, an air conditioner of the present invention includes a front frame, a suction grill provided rotatably on the front frame, an air cleaner, and an on / off switch of the air cleaner. A detection unit that determines the detection, a projection that contacts the detection unit when the suction grill is closed, and a projection that is provided on the front frame and protrudes more forward than the detection unit. comprising a convex portion provided so surround, which was provided with a convex rib so as to surround the convex portion in a position opposite to the convex portion of the suction grille, and convex ribs suction grille Since the position is regulated by the convex portion of the front frame, it is possible to prevent breakage of the protrusion provided on the suction grille during product transportation.

  In the air conditioner of the present invention, since the protrusion provided on the suction grille is not damaged during transportation, quality assurance during transportation of the product can be reliably performed.

1st invention is provided in the said front grille, the suction grill rotatably provided in the said front frame, the air cleaner, the detection part which judges the on / off of the switch of the said air cleaner, and the said suction grill And a projecting portion that comes into contact with the detection portion when the suction grill is closed, and a convex portion that is provided on the front frame and protrudes to the front of the detection portion so as to surround the detection portion. A convex rib is provided so as to surround the convex portion at a position opposite to the convex portion of the suction grill, and the position is regulated by the convex rib of the suction grill and the convex portion of the front frame. Therefore, it is possible to prevent the protrusions provided on the suction grille from being damaged during product transportation.

  In the second invention, in particular, a substantially triangular rib is provided inside the convex rib provided in the suction grill of the first invention, and the convex portion of the front frame is guided by the rib. The operation of the detection unit is surely performed.

  In the third invention, in particular, an air filter for collecting dust is provided on the front frame of the first or second invention, and the tip of the convex rib abuts against the frame portion of the air filter when the suction grill is closed. In this way, the warping of the air filter is corrected, and the operation of the air conditioner is ensured without the air filter being lifted during the operation of the air conditioner.

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

(Embodiment 1)
1 is a side view of an indoor unit of an air conditioner according to a first embodiment of the present invention, FIG. 2 is an enlarged cross-sectional view of a part A in FIG. 1, and FIG. 3 is a partial front view of the air conditioner. is there.

  1 and 2, the indoor unit 1 turns on and off a front frame 1a constituting the exterior, a suction grill 2 rotatably attached to the front frame 1a, and a switch (not shown) of the air cleaner 12. And a convex portion 4 provided on the front frame 1a, and a convex rib 5 provided on the suction grill 2 and surrounding the convex portion 4 of the front frame 1a.

  Reference numeral 6 denotes a protrusion for operating the detection unit 3 for operating on / off of the air cleaner 12 provided in the suction grill 2, and reference numeral 7 denotes a protrusion for the operation of the detection unit 3 inside the front frame 1 a. This is a hole necessary for performing by the portion 6.

  In the figure, reference numeral 8 denotes an insertion portion of the suction grill 2 provided on the front frame 1 a for rotating the suction grill 2. Reference numeral 9 denotes a screw attachment portion for fixing the front frame 1a to a frame (not shown).

  1 to 3, the convex portion 4 provided on the front frame 1 a is surrounded in proximity to the convex rib 5 provided on the suction grill 2, so that when the product falls to guarantee product transportation, Since the convex-shaped part 4 of the frame 1a and the convex-shaped rib 5 provided on the suction grill 2 are in contact with each other and the vertical and horizontal movements are restricted, the projection 6 provided on the suction grill 2 is not damaged, The operation of the detection unit 3 that operates turning on and off of the air cleaner 12 is ensured.

In order to improve the performance of the air cleaner 12, it is generally known to increase the size. The same applies to the air cleaner 12 in the present embodiment, and the air cleaner 12 occupies more than half of the suction size of the indoor unit 1. Therefore, since it takes out at the time of the maintenance of the air cleaner 12, the right or left becomes large, and the size of the air filter 11 must be large on the right or left. As a result, the large air filter 11 is affected by warpage, and both ends thereof float and a gap is formed between the front frame 1a, and dust or the like is sucked from the gap, which hinders the operation of the air conditioner. become.

  In the present embodiment, as shown in FIG. 6, when the suction grille 2 is closed, the end surface of the convex rib 5 provided on the suction grille 2 is brought into contact with the frame portion 11a of the air filter 11. When the grille 2 is closed, the convex rib 5 pushes the frame portion 11a of the air filter 11, so that there is no gap between the front frame 1 and the air filter 11, and the air conditioner operates reliably without sucking dust. be able to.

  As described above, in the air conditioner according to the present invention, the projection that operates the detection unit that determines whether the air cleaner is turned on or off is not damaged during transportation, and the opening / closing member provided with the projection The present invention can also be applied to various devices and apparatuses having the above.
