DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filter mounting device for a total heat exchanger provided in an individual type air conditioner.

[0002]

2. Description of the Related Art In recent years, an air conditioner has been required to be provided with a total heat exchanger for heat recovery for energy saving and to recover exhaust heat when ventilating to reduce an air conditioning load.

Conventionally, it is known this kind of individual Katachisora air harmony machine, to perform the outdoor unit portion, and the interior unit, between this outdoor unit section and the interior unit, a heat recovery while performing ventilation The total heat exchanger is provided.

As shown in FIG. 4, the total heat exchanger has suction surfaces 102 and 103 of a total heat exchanger 101, and the suction surfaces 102 and 103 have filters held by frames 104 and 105, respectively. 106 and 107 are provided. The frame 104
105 has handles 108 and 109, respectively, and one frame 104 is held by an upper bent piece 110 and a lower bent piece 110a.

On the other hand, the frame 105 is held by an upper bent piece 111 and a lower bent piece 111a. The upper bent piece 1
10 and 111 are constituted by a top plate 112, and the lower bent pieces 110 a and 111 a are constituted by a bottom plate 113.

In the above configuration, the suction surfaces 102 and 103
The filters 106 and 107 mounted on the filter are periodically cleaned for maintenance. At this time, the handle 108 of one of the filters 106 is pulled out in the direction of arrow A, and the other filter 107 moves the handle 109 by the arrow. B was removed in the direction shown by B and washed, and after such maintenance was completed, they were mounted on the suction surfaces 102 and 103 again.

[0007]

In such a conventional filter mounting apparatus, upper bent pieces 110 and 111 and lower bent pieces constituted by a top plate 112 and a bottom plate 113 for holding the filters 106 and 107 are provided. 110a ・ 111a
And other parts are required, which increases costs
And the filters 106 and 107 must be attached and detached separately from each other.
There was a problem that complexity was great .

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems and provides a total heat exchanger in which a filter can be easily attached to a total heat exchanger without using a top plate for forming a bent piece or a bottom plate. It is an object to provide a filter mounting device.

[0009]

According to the present invention, there is provided an air filter comprising a frame made of resin, wherein a filter material is mounted on an exhaust surface and an intake surface of a total heat exchanger. The air filter includes a handle protruding between the intake surface and the exhaust surface, and a holding piece covering a part of the exhaust passage surface and the intake passage surface of the total heat exchanger. It is.

[0010]

According to the present invention, when the total heat exchanger is taken out, the handle portion is gripped with a finger and taken out by the holding piece when pulled out, and when the air filter is removed, the holding piece is made of resin elasticity. It can be spread out and removed by using, and after cleaning it can be spread out by using the resin elasticity and installed over a part of the exhaust passage surface and the intake passage surface, and the air filter on both sides can be attached and detached at the same time .

[0011]

1 to 3 show an embodiment of the present invention.
This will be described with reference to FIG.

[0012] Figure 3 is a perspective view of an individual Katachisora air harmonization machine 2 wearing the total heat exchanger 1, an outdoor unit 3, more composed and interior unit 4. When exhausting indoor air, the total heat exchanger 1 is provided with an exhaust filter 5 in order to prevent dust from indoor air from contaminating the total heat exchanger 1, and when taking outside air into other sides. If the outside air is dirty, the intake filter 6 is provided to prevent clogging of the total heat exchanger 1 and intake of dust into the room.

1 and 2, the structure of the total heat exchanger 1 will be described. That is, the vertical surface of the total heat exchanger 1 has an exhaust surface 7 for exhausting indoor air and an intake surface 8 for taking fresh air from outside.
An air filter 9 is provided over the air intake surface 8.

The air filter 9 is formed integrally with the exhaust surface 7 and the intake surface 8 and is provided in a double airfoil shape. The filter material 1 is mounted on frames 10 and 11 made of resin.
2.13 is installed.

The air filter 9 is provided at the center between the exhaust surface 7 and the intake surface 8 so as to protrude slightly therefrom, and has a handle 14 having a substantially square shape. At both ends of the frames 10 and 11, holding pieces 17 and 18 formed so as to cover a part of the exhaust passage face 15 and a part of the intake passage face 16 are provided. The air filter 9 is attached and detached.

With the above-described configuration, the dust that is generated when the indoor air is exhausted from the exhaust surface 7 is removed by the filter material 12 to prevent the total heat exchanger 1 from being soiled, and the intake surface 8 is also protected from outside air. When the inflowing air is dirty, dust is removed by the filter material 13 to prevent the total heat exchanger 1 from being soiled, and purified fresh air is taken into the room. Next, the air filter 9 is periodically cleaned. At this time, the entire heat exchanger 1 is pulled out by the holding pieces 17 and 18 by holding the handle 14 by hand and pulling the handle 14 toward the user.・ The air filter 9 is removed and washed while spreading 18 by the resin elasticity. When this cleaning is completed, the holding pieces 17 and 18 are spread again, and the air filter 9 is attached so that the holding pieces 17 and 18 are hung on a part of the exhaust passage surface 15 and the intake passage surface 16. The attachment / detachment described above is performed so that the holding pieces 17 and 18 are widened, but the attachment / detachment may be performed by sliding up and down.

As described above, according to the filter mounting apparatus of the embodiment of the present invention, the attachment and detachment of the air filter 9 becomes very simple, and the cost is reduced and the cleaning work is simplified by simplifying the configuration.
The complexity can be reduced by facilitating the operation.

[0018]

As is apparent from the above embodiment, according to the present invention, an air filter having a handle formed integrally with the exhaust surface and the intake surface of the total heat exchanger and projecting to the center is provided. provided, this air filter, a holding piece which is subjected to a portion of the intake passage faces the exhaust passage plane provided to attach and detach the total heat exchanger Ri by the holding piece, and the holding piece extended by resin elasticity Because the air filter is attached and detached, the total heat exchanger can be easily attached and detached.In addition, the air filter can be attached and detached only by expanding the holding piece, so that both the exhaust and intake surfaces can be attached and detached at once. It becomes possible. In addition, unlike the conventional air filter holding device that uses a top plate and a bottom plate, the top plate and the bottom plate are not required, so that significant cost reductions can be achieved and further easy attachment and detachment.
Accordingly, it is possible to provide a filter mounting device that can reduce the complexity of the cleaning operation .
