Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner equipped with a heat exchanger, a drain pan and an air filter.

[0002]

2. Description of the Related Art As a conventional air conditioner, there is one proposed by the present applicant as Japanese Patent Application No. 2-151017.

This air conditioner is mainly composed of an air conditioner main body suspended in a ceiling space and a decorative panel attached to the lower part of the main body.

An air filter for removing dust in the air is attached to the leeward side of the suction grill formed on the decorative panel.

[0005]

The above-mentioned air conditioner requires a fixture for fixing the air filter to the decorative panel, and the cost of the fixture itself and the labor required to attach the fixture to the decorative panel. There was a drawback that required.

Further, the air filter and the like are liable to drain when the cooling operation of the air conditioner is stopped, and this drain may drip outside the drain pan. is there.

The present invention provides an air conditioner which does not require a fixing tool for fixing an air filter, and moreover the drain of the air filter is less likely to drip outside the drain pan.

[0008]

According to the present invention, a heat exchanger and a drain pan for receiving drain from the heat exchanger are provided.
In an air conditioner including an air filter on the windward side of the heat exchanger, the air filter is provided with a fitting for attaching to a drain pan at a lower end thereof.

[0009]

In this air conditioner, since the air filter can be attached to the drain pan with the air filter attachment, a separate member for attaching the air filter is not required.

Moreover, the drain attached to the air filter is guided to the drain pan through the fixture.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings.

Reference numeral 1 denotes an air conditioner main body suspended by a suspending tool 3 attached to four hanging bolts 2 embedded in a building and suspended, and 4 a decorative panel, which is an indoor unit. Make up 5.

The decorative panel 4 is provided with a suction port 7 with a suction grill 6 and an air outlet with a wind direction changing plate 8.

Reference numeral 9 is a first air filter attached to the lee of the suction grill 6.

10 and 11 are cross-flow fans provided in the main body 1, 12 and 13 are heat exchangers arranged in a substantially V shape between the fans, and 14 is a drain from the heat exchanger. The drain pan, 15 is a drain pump for sucking up the drain in the drain pan and discharging the drain out of the main body.

Reference numeral 16 is a second air filter, which is composed of a main frame 17, an auxiliary frame 18, and a filter element 19 sandwiched between these two frames.

The main frame 16 has a hole 25 shaped like a combination of a round hole and a rectangular hole larger than this hole, a color sample label 20 showing the degree of contamination of the filter element 19, and a mounting leg 21. An attachment 23 for attaching to the upper edge 22 of the drain pan and a net 24 are provided.

The auxiliary frame 18 is provided with a hooking piece 26 hooked on the main frame 17 and a lattice 27 for pressing the filter element 19.

The main frame 17 and the auxiliary frame 18 are made of synthetic resin, and both frames have an elastic force that is easily deformed by the force of the hand.

The filter element 19 is a charging filter 28.
And a deodorizing filter 29.

Reference numeral 30 denotes a shaft for connecting the two air filters 16, and a hooking piece 31 for catching the air filter 16 so as not to come off from the air filter 16 and a handle 32 for holding the air filter 16 when the air filter 16 is attached and detached. Has been.

Reference numeral 33 is a shaft fixture attached to the inner wall of the main body 1.

Reference numeral 40 is a ceiling plate.

In the air conditioner thus constructed, 2
After assembling one air filter 16 with the two shafts 30, the fixture 23 of the air filter 16 is attached to the upper edge 22 of the drain pan 14, and the shaft 30 is fixed to the fixture 23.
The air filter 16 is attached to the main body 1 so as to fit in the.

At this time, if the air filter 1 is attached by gripping the handle 32 of the shaft 30, it is easy to attach.

Since the air filter 16 is attached by an elastic force so as to be slightly stretched between the upper edge 22 of the drain pan 14 and the shaft fixture 33, not only the attachment but also the
It is also easy to remove.

Since the air filter 16 is attached to the main body 1, the vibration noise is less likely to be generated as compared with a case where the air filter 16 is a separate member and is attached to a decorative panel which is likely to cause vibration noise.

Further, the shaft fixing member 33 is not always necessary because it only prevents the air filter 16 from being displaced, and the air filter 16 can be attached to the drain pan 14 only by the attaching member 23.

For this reason, the cost of the fixture itself and the labor for attaching the fixture can be saved.

Moreover, the air filter 16 can be attached to the drain pan 14, and the air filter 1
No separate member for attaching 6 is needed, so it is already installed and air filter [air cleaning filter]
You can also install an air filter on an air conditioner that is not equipped with.

Further, the air filter 16 is the heat exchanger 1.
2, 13 and the air filter 16 are separated from each other, the ventilation resistance is smaller than that when the air filter 16 is installed close to the heat exchangers 12, 13 or the air filter 9, and the dust collecting capability of the air filter 16 is improved. It can be fully demonstrated.

When the cooling operation of the air conditioner is stopped, the air filter 16 is cooled because it is near the heat exchanger,
Drain may adhere, but since this drain is guided to the drain pan 14 through the fixture 23 of the air filter 16, it is difficult for the drain to drip outside the drain pan 14.

[0033]

The present invention provides an air conditioner equipped with a heat exchanger, a drain pan for receiving drainage from the heat exchanger, and an air filter on the windward side of the heat exchanger. Since the attachment for attaching to the drain pan is provided at the lower end of the drain pan, the attachment of the air filter can be attached to the drain pan, and the cost of a separate member for attaching the air filter and the labor for installing the separate member can be saved.

Moreover, since the drain attached to the air filter is guided to the drain pan through the attachment, it is possible to prevent the drain from dripping outside the drain pan.
