Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a mounting device for an air filter in a window-mounted air conditioner.

Conventional Structure and Problems Conventionally, a filter mounting device for a window-mounted air conditioner of this type has been structured as shown in FIGS. 1 to 4.

That is, in the same figure, 1 is the front grill;
A suction port 2 and a blowout port 3 are provided on the front surface thereof. Reference numeral 4 denotes an outer box that forms the window-mounted air conditioner main body A, and inside it there is a compressor, an outdoor heat exchanger (none of which are shown), and an indoor heat exchanger that together with these constitutes a well-known refrigeration cycle. Vessel 5
and a blower (not shown) are respectively provided. 6 is the right side plate of the indoor heat exchanger 5, and the stabilizer 7 of the blower (cross flow fan)
is fixed with screws 8. Reference numeral 9 denotes an air filter, and as shown in FIG. 4, a handle 11 is provided on the front portion 10 of the air filter. This air filter 9
is inserted between a pair of upper and lower guide ribs 12a, 12b located at a predetermined interval in the vertical direction on the inner surface of the front grille 1 and extending in the horizontal direction, and movement in the vertical direction is controlled by these guide ribs 12a, 12b. In addition, it is sandwiched between a wire mesh 13 attached to the front side of the indoor heat exchanger 5 and the inner surface of the front grille 1, and its movement in the front-back direction is restricted. The wire mesh 13 has one end 14 formed into a U-shape to sandwich the indoor heat exchanger 5, and the other end 15 penetrated into a notch (not shown) in the side plate 6 to improve its own elasticity. is fixed.

However, in this structure, the guide ribs 12a, 12
Since the height of b is low, these guide ribs 12a, 12
The distance T from the tip of b to the indoor heat exchanger 5 is larger than the plate thickness t of the air filter 9, and when the air filter 9 is inserted, the air filter 9 falls into the distance T, resulting in poor insertion operability.
Furthermore, when the air filter 9 is installed, the air filter 9 vibrates due to vibrations during operation and generates noise.

As a measure to eliminate the above drawback, the guide rib 12
It is conceivable to increase the protruding dimensions of a and 12b. However, this structure is not preferable because, due to thermal deformation of the front grille 1, the front grille 1 warps and the guide ribs 12a, 12b come into contact with the front surface of the indoor heat exchanger 5. That is, since condensed water is flowing down the front surface of the indoor heat exchanger 5, there is a problem that the flowing water flows particularly into the lower guide rib 12b and drips from the main body A onto the floor surface or the like.

OBJECT OF THE INVENTION The present invention solves the above-mentioned conventional drawbacks.
The purpose is to facilitate insertion and withdrawal of the air filter, and to ensure dew removal processing.

Structure of the Invention In order to achieve this object, the present invention provides a pair of protrusions at both upper and lower ends of the tip of the air filter that abuts the inner surface of the front grille, and measures the dimension from the back surface of the air filter to the tip of the protrusion in the indoor heat source. This is larger than the gap between the exchanger and the guide rib.

With this configuration, even if the air filter comes off the tip of the guide rib and attempts to fall between the indoor heat exchanger and the air filter, the protrusion is locked to the guide rib to prevent the air filter from falling, and also prevents the air filter from falling due to thermal effects. Even if the front grille is warped, the tips of the guide ribs are prevented from coming into contact with the front surface of the indoor heat exchanger.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 5 to 5 of the accompanying drawings.
This will be explained with reference to FIG. Here, Figures 1 to 4
Components that are the same as those in the drawings are designated by the same numbers and their explanation will be omitted, and only the different parts will be explained.

In the figure, a pair of guide ribs 12a and 12b formed on the inner surface of the front grille 1 are connected to a wire mesh 13 which is the front surface of the indoor heat exchanger 5 as far as the design allows.
It is extended so that the distance t between the two ends becomes smaller. Further, the air filter 9 has a tip 9 as shown in FIG.
a is bent toward the inner surface of the front grille 1 to facilitate the insertion and withdrawal of the air filter 9, and its upper and lower ends 9b and 9c are tapered to facilitate the insertion and withdrawal of the air filter 9. has been done. Reference numeral 9d denotes a semicircular protrusion that is integrally formed in the air filter 9 so as to protrude toward the inner surface of the front grille 1, and is formed at the beginning of the bend of the tip 9a. The protrusion dimension of the protrusion 9d is such that the dimension l from the back surface of the air filter 9 to the tip of the protrusion 9d is larger than the distance t from the tips of the guide ribs 12a, 12b to the wire mesh 13, which is the front surface of the indoor heat exchanger 5. It is set like this. Further, the distance L from the suction port 2 to the wire mesh 13 is formed to be equal to the dimension l.

In the above configuration, when inserting the air filter 9, the air filter 9 is inserted from the outlet 3 side and interposed between the guide ribs 12a and 12b of the front grille 1. By continuing to insert the air filter 9 in this state, the air filter 9
The installation is completed. Here, when inserting the air filter 9, the tip 9a of the air filter 9 comes off the guide rib 12b and the indoor heat exchanger 5
If the air filter 9 attempts to fall between the two, the protrusion 9d engages with the guide rib 12b, thereby preventing the air filter 9 from falling off.

Therefore, the guide rib 12b of the air filter 9
Since the air filter 9 falls between the air filter 9 and the indoor heat exchanger 5, there is no problem with the insertion or withdrawal operation of the air filter 9, and the usability is improved. Also, compared to the conventional structure, there is a protrusion 9d on the air filter 9.
Since the air conditioner main body A only needs to be formed, it can be manufactured at low cost, and the air conditioner main body A can be made more versatile. Moreover, since the protrusion 9d is semicircular, it does not get caught on the inner surface of the front grille 1 when the air filter 9 is inserted.
Attachment and detachment becomes very smooth. Furthermore, since the distance L between the wire mesh 13 and the intake port 2 is formed to be slightly larger than or equal to the above-mentioned dimension l, the tip 9a of the air filter 9 and the protrusion 9d come into contact with the inner surface of the front grille 1, causing vibrations caused by air conditioning operation. It can also eliminate noise. In addition, since the protrusions 9d are only partially provided, the plate thickness of the air filter 9 can be kept thin, and the air filter 9 does not lose the flexibility of the synthetic resin, making it flexible when attaching and detaching the air filter 9. is the same as before. Further, the front grille 1 warps due to the influence of heat, and the guide ribs 12a, 1
2b does not come into contact with the front surface of the indoor heat exchanger 5, the dew on the indoor heat exchanger 5 does not travel along the guide ribs 12a, 12b and drip onto the floor surface, ensuring reliable dew treatment. I can do it.

Effects of the Invention As is clear from the above embodiments, the air filter mounting device for a window-mounted air conditioner according to the present invention is provided with protrusions that come into contact with the inner surface of the front grill at both upper and lower ends of the tip of the air filter, and protrusions protrude from the back surface of the air filter. The dimension to the tip is made larger than the gap between the indoor heat exchanger and the guide rib, so when inserting the air filter, it is possible to prevent the air filter from falling into the gap and getting caught, which will hinder operation. In addition, the dimensions of the guide ribs can be considered to prevent the guide ribs from coming into contact with the front surface of the indoor heat exchanger even if the front grill warps due to thermal effects. This has various advantages, such as preventing dew from dripping onto the floor surface along the guide ribs and damaging the floor surface.
