Description

[Detailed description of the invention] This invention relates to the improvement of air conditioners that have a filter mounting structure that allows the filter to be attached and removed by sliding it from the front or side, and allows for reliable installation without rattling. One of its purposes is to do so.

Conventionally, the structure of installing the filter in this type of air conditioner was that it was located on the leeward side of the suction port, and the filter was installed and removed by sliding it from the front in the depth direction of the main unit, and it was installed separately to prevent rattling. A structure in which one end of the filter is fixed using a spring member or the like, or a structure in which the filter frame is formed of resin or the like and uses its own flexural elasticity to prevent rattling is known.

However, in the former case, parts for fixing are required, which poses a problem in terms of assembly man-hours, and in the latter case, since it is made of resin, it cannot be placed close to the heating source, and installation is difficult depending on the location. There were problems such as being subject to restrictions.

In view of the above-mentioned conventional problems, the present invention provides a structure in which the filter can be mounted without being restricted by the location and without rattling.

Hereinafter, the present invention will be described with reference to the accompanying drawings showing one embodiment thereof.

In the figure, reference numeral 1 denotes the main body of the air conditioner, which has an air outlet 2 at the top of the front and an inlet 3 at the bottom. An exchanger 6 and a panel heater 7 having a well-known configuration that also serves as a front decorative panel are provided.

Reference numeral 8 denotes a filter mounting section provided at the lower end of the panel heater 7, located on the leeward side of the suction port 3, and provided with a pair of left and right support rails 9, 10.

These support rails 9, 10 have upper sides 9a, 10, respectively.
a and lower sides 9b and 10b, and is formed in a U-shape in cross section.

11 is an air filter, and a filter cloth 12 made of non-woven fabric
, a filter frame 13 made of metal, and this filter frame 1
3 and the filter cloth 12, and remove the filter cloth 1.
The filter frame 14 is made of a slightly flexible heat-resistant resin that prevents the filter from bending.

Here, the filter frame 13 and the filter frame 14 each have a recess 13a for positioning, a protrusion 14a that fits into the recess 13a, and a projection 14a that allows the filter frame 14 to fall off so that the connection can be performed as specified. A presser piece 13b is provided for preventing this.

Here, the protrusion 14a slightly protrudes outward from the side of the filter frame 13 so that the width t of the air filter 11 and the interval T between the support rails 9 and 10 are equal.

In the above configuration, to assemble the air filter 11, the filter cloth 12 is placed on the filter frame 13, and the filter frame 14 is slightly bent using its own elasticity.
Positioning is performed by fitting the recess 13a and the protrusion 14a, and the assembly is completed.

Then, by inserting this air filter 11 between the support rails 9 and 10, the installation of the air filter 11 is completed.

At this time, the contact points between the support rails 9, 10 and the air filter 11 are mainly at the tips of the protrusions 14a and the lower sides 9b, 10b.
Therefore, friction is low and attachment and detachment are easy.

Furthermore, since the protrusions 14a protrude to be equal to the interval T between the support rails 9 and 10, positioning in the left and right direction is possible, and rattling can be prevented.

Furthermore, although the air filter 11 is susceptible to heat from the panel heater 7, since the metal filter frame 13 is used, it is not deformed by heat and always performs the filter function as set.

Note that the filter may be inserted not only from the front but also from the side, and it goes without saying that the same configuration can be used in this case as well.

As is clear from the above embodiments, the structure of the air conditioner filter installation according to the present invention is that the filter is provided with a metal frame to prevent deformation of the air filter, which is susceptible to thermal effects, and the filter cloth is attached to this metal frame. Since the filter frame is positioned using protrusions to fix the filter frame, assembly is easy.Moreover, in order to prevent the protrusions from wobbling between the support rail and the filter, a separate member for preventing wobbling is also included. This has various advantages, such as eliminating the need.
