Description

[Detailed description of the invention]

[0001]

[Field to which the invention belongs]

 The present invention relates to an air conditioner in which an air cleaning filter for an air conditioner is attached outside a suction grill.

[0002]

2. Description of the Related Art and Problems to be Solved

 A conventional air conditioner with an air purifying function is equipped with an electrostatic filter separately from a net filter for dust removal.

[0003] A mesh filter can be used repeatedly by cleaning or washing with a vacuum cleaner, but an electrostatic filter has no air purifying function unless it is replaced with a new one if the dust collecting capacity is limited. equal. Nevertheless, replacement electrostatic filters do not sell as much at all when compared to the number of air conditioners shipped with air purifying functions. This means that even after the replacement period of the electrostatic filter, it has been used without any effect.

[0004] The reason is that the electrostatic filter is set at a position that is difficult to see behind the mesh filter, so it is difficult to use the electrostatic filter without knowing the existence of the electrostatic filter or to know when to replace it visually. This is because it is not possible or it is not easy to replace it.

[0005] The present invention solves the above problem by attaching an air purifying filter to the outside of the suction grill of the air conditioner.

[0006]

[Means to solve the problem]

 The air conditioner with an external air purifying filter according to the present invention uses an air purifying filter (1) containing an electrostatic filter (3) in a frame (2) and a suction grill (61) of an air conditioner (6). It is configured to be replaceably attached to the front side by locking means provided on the frame (2). The frame (2) can be a flat body made of paper. The locking means provided on the frame (2) may be an adhesive tape.

[0007]

[Action and effect]

 Since the air cleaning filter (1) is installed on the outer surface of the suction grille (61) of the air conditioner (6), the air cleaning filter (1) can be seen at a glance to see if it is dirty over time. There is no mistake.

[0008] The external air purifying filter (1) becomes conspicuous when the dust collecting capacity is limited, so it is necessary to replace the air purifying filter (1). Replacement at the appropriate time will maintain the air cleaning function.

If the air purifying filter (1) is housed in the flat frame (2), it does not become bulky, and if the adhesive tape (5) is set on the back surface of the frame (2), no technology is required. Anyone can easily attach it to the air conditioner (6). Also, by pulling the frame (2), it can be easily removed from the air conditioner (6).

Further, if the air cleaning filter (1) is attached to the outer surface of the suction grill (61) of the air conditioner (6) with an adhesive tape (5), the manufacturer and model of the air conditioner (6) can be changed. The air purifying filter (1) can be installed without choosing.

[Embodiment of the invention]

 FIG. 1 shows an air cleaning filter (1), an internal electrostatic filter body (3) and a deodorizing body (4).

The air purifying filter (1) includes a flat paper frame (2) containing an electrostatic filter body (3) and a deodorizing body (4).

The frame 2 has a length of about 300 mm, a width of about 60 mm, and a thickness of about 6 mm, and has a window hole 21 occupying most of the front and back surfaces. Both ends of the frame (2) are closed by bonding an end member (22) made of foamed resin.

The electrostatic filter body (3) is formed by alternately repeating a mountain-like fold and a valley-fold of a fibrous breathable band sheet in accordance with the size of the frame (2). Are charged with static electricity and trap microscopic dust floating in the air.

The deodorizing body (4) is a perforated sheet body having a thickness of about 0.2 mm, which is obtained by immersing a net in a tank in which powder of activated carbon and binder are mixed, pulling it up, and drying it. It is formed according to the size of the frame (2).

The electrostatic filter body (3) and the deodorizing body (4) are accommodated in the frame body (2) in an overlapping manner, and the frame body (2) has the back side on the deodorizing body (4) side.

An adhesive tape (5) is set on both ends of the back surface of the frame (2) with the adhesive surface (50) facing outward, and a release paper (51) covers the adhesive surface (50). The pressure-sensitive adhesive tape (5) of the embodiment is a double-sided pressure-sensitive adhesive tape, and is also adhered to the frame (2) with the pressure-sensitive adhesive surface of the pressure-sensitive adhesive tape (5).

At one end of the front surface of the frame 2, a brown display section 23 and a gray display section 24, which are indications of contamination of the electrostatic filter body 3, are color-printed.

However, the air cleaning filter (1) is attached to the suction grill (61) of the air conditioner (6). It is not necessary to attach the air cleaning filter (1) to the entire surface of the suction grill (61), and only the portion corresponding to the suction portion of the suction grill (61) is sufficient. Generally, two air cleaning filters (1) are sufficient. Since the adhesive tape (5) with release paper (51) is set on the back of the frame (2) of the air purification filter (1), only the peeling of the release paper (51) requires skill. Anyone can easily attach the air purifying filter (1) to the air conditioner (6).

When the dust collecting capacity of the external air purifying filter (1) reaches the limit, the dirt becomes conspicuous, so it is tempting to replace it even if it is not possible. Never. The brown display (23) printed on the frame (2) is a guide for replacement of dirt by cigarettes, and the gray display (24) is a guide for replacement by general dirt. It is easier to understand when to replace the clean filter (1).

By replacing the air cleaning filter (1) at an appropriate time, the air cleaning function is maintained. As in the embodiment, if only two air cleaning filters (1) are attached to the suction grill (61), 75% of the air sucked by the air conditioner (6) passes through the air cleaning filter (1). do not do. However, assuming that the total amount of air in the room of 6 tatami mats is sucked in 15 minutes, all air in the room is passed through the air purifying filter (1) per hour. Is enough. The deodorizing body (4) built in the air purifying filter (1) can also remove odors in the room. The air purification filter (1) is housed in the flat frame (2) and is not bulky. By pulling the frame (2), it can be easily removed from the air conditioner (6).

Further, since the air conditioner (6) is attached to the outer surface of the suction grill (61) with the adhesive tape (5), the attachment can be performed without selecting a manufacturer and a model of the air conditioner (6). Since the paper frame (2) can be manufactured at low cost and is lightweight, even if it is attached to the suction grille (61) of the air conditioner (6), no load is applied to the suction grille (61).

In carrying out the present invention, the frame body (2) is not limited to a paper-made one, but may be a synthetic resin or a non-woven fabric, etc., as long as it is lightweight and can be used at a low cost. Further, the shape of the air cleaning filter (1) is not limited to a flat body, and the shape is not limited as long as it can be stably attached to the suction grill (61). Further, the means for locking the air purifying filter (1) to the suction grill (61) is not limited to the adhesive tape (5), but fits tightly into the gap between the suction grill (61) and the frame (2). Any shape and material can be used as long as it can be attached to and detached from the suction grille (61) from the front side, such as by projecting a spring-made retaining piece.

It should be noted that the air conditioner in the present invention naturally includes not only a cooling / heating machine, but also a heating machine, a cooling machine, and a dehumidifying machine.
