Abstract

PROBLEM TO BE SOLVED: To prolong a time interval for dust removal for an internal instrument and reduce the cost. SOLUTION: A first air filter 19 is horizontally disposed at a boundary between an air intake chamber 12 and a fan chamber 13 such that a front panel 26 is easily taken out without its being demounted. A second air filter 23 is horizontally disposed on an upper part of a blowoff outlet 22 of a fan 15 in a heat exchange chamber 14 and behind a drain pan 25 such that the front panel 26 can not be taken out without its being demounted. Thus, even when the first air filter 19 is demounted owing to mischief, air containing dust taken in from the inside of a room is prevented from being sent intactly to an internal instrument of a heat exchanger 16, and hence a time interval for dust removal for the internal instrument is prolonged and the cost of dust removal for the internal instrument is reduced.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to improvement of an air filter mounting structure for an air conditioner.

[0002]

2. Description of the Related Art Usually, an air filter of an air conditioner is installed at a position where anyone can easily remove it so that the user can easily clean it when it becomes clogged. For example, a floor-standing fan coil unit 1 as shown in FIG.
In general, an air filter 5 is horizontally arranged at the boundary between the air intake chamber 2 having a suction port 2a on the front surface and the fan chamber 4 accommodating the fan 3. This air filter 5
It can be easily pulled out forward without removing the front panel 8.

[0003]

However, in the above conventional fan coil unit 1, since the air filter 5 is attached so that anyone can easily pull it out, the air filter 5 is removed by mischief or the like and the air filter 5 is removed. It is often operated without a filter. In that case, the dust-containing air taken in from the room is sent to the heat exchange chamber 6 as it is, and a great deal of cost and man-hours are required to remove the dust adhering to the internal equipment such as the heat exchanger 7. And are required. The above-mentioned problem is not limited to the fan coil 1 having the structure shown in FIG. 3, but is a problem that occurs in all air conditioners that are set in places where an unspecified number of people easily touch.

SUMMARY OF THE INVENTION An object of the present invention is to provide an air filter mounting structure for an air conditioner which can extend the period for removing dust from internal equipment and reduce costs.

[0005]

In order to achieve the above-mentioned object, the invention according to claim 1 supplies indoor air taken in from a suction port by rotation of a fan to a heat exchanger so as to be connected to the heat exchanger. In the air filter mounting structure of the air conditioner that blows out the air after heat exchange into the room from the outlet, it is placed between the suction port and the fan at a position where it can be taken out without removing the front panel, and the taken-in room The first air filter for removing dust from the air and the first air filter disposed between the fan and the heat exchanger where the front panel cannot be taken out without removing the front panel, and removes dust in the air from the fan. It is characterized by having two air filters.

In the above structure, normally, the dust in the room air is removed by the first air filter arranged between the suction port and the fan. Then, when cleaning the first air filter, it is easily taken out without removing the front panel. Further, when the first air filter is removed by mischief or the like, the dust in the indoor air from the fan is located between the fan and the heat exchanger and cannot be taken out without removing the front panel. The second air filter is removed.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in detail below with reference to the embodiments shown in the drawings. FIG. 1 is an internal side view of a floor-standing fan coil unit to which an air conditioner mounting structure for an air conditioner according to the present embodiment is applied.

This fan coil unit 11 is installed on the floor and has an air intake chamber 12 for taking in indoor air, a fan chamber 13 for accommodating a fan 15, and a heat exchange chamber 14 for accommodating a heat exchanger 16. Has a structure in which the layers are sequentially laminated. Then, by the rotation of the fan 15, the air intake chamber 1 is introduced from the suction port 17 provided on the front surface of the air intake chamber 12.
The indoor air taken in 2 flows into the fan chamber 13,
It is sent to the heat exchange chamber 14 by the fan 15. Then, as shown by the arrow (A), after exchanging heat with the heat exchanger 16, the air outlet 18 provided in the upper part of the heat exchange chamber 14
From the room.

The fan coil unit 11 in this embodiment accommodates two air filters. One of them is arranged at the boundary between the air intake chamber 12 and the fan chamber 13 like the conventional fan coil unit 1 shown in FIG. The first air filter 19 is supported by support members 20 provided on both sides of the upper portion of the air intake chamber 12 and is horizontally inserted, and is provided at the boundary between the air intake chamber 12 and the fan chamber 13 on the rear wall of the casing. The rear end is held by the holding member 21 and is horizontally arranged. Then, at the time of cleaning, the front panel 26 is pulled out and taken out without removing the front panel 26.

The other air filter is arranged above the air outlet 22 of the fan 15 in the heat exchange chamber 14. The second air filter 23 is used in the heat exchange chamber 1
4 are guided in the front-rear direction by guide members 24 provided on both sides of the fan 4, and are inserted horizontally, and are horizontally arranged so as to cover the upper portion of the blowout port 22 of the fan 15. A drain pan 25 is disposed immediately in front of the second air filter 23 so that the drain pan 25 cannot be pulled out without removing the drain pan 25 during cleaning.

When taking out the second air filter 23, the following procedure is carried out. First, FIG.
As shown in, the front panel 26 of the fan coil unit 11 is removed, and the drain pan 25 is taken out. After that, the second air filter 23 is pulled out forward as shown in FIG. That is, the second air filter 23
Since the front panel 26 cannot be taken out without removing the front panel 26, it cannot be easily removed by mischief or the like.

As described above, the fan coil unit 11
In the same manner as in the conventional fan coil unit, the heat exchange with the first air filter 19 which is disposed horizontally at the boundary between the air intake chamber 12 and the fan chamber 13 and can be easily taken out without removing the front panel 26 is performed. Two air filters are provided horizontally above the air outlet 22 of the fan 15 in the chamber 14 and cannot be pulled out unless the front panel 26 is removed and the drain pan 25 is removed. Therefore, even if the first air filter 19 is removed by mischief or the like, the dust in the indoor air taken in is removed by the second air filter 23, so that the air containing the dust taken in from the room remains as it is. It is never sent to 16. That is, according to the present embodiment, the second
Cleaning of internal equipment such as the heat exchanger 16 located downstream of the air filter 23 is completely eliminated, and the period for removing dust of the internal equipment is extended to reduce the cost and man-hours for removing dust of the internal equipment. it can.

In the normal case where the first air filter 19 is attached, most of the dust in the room air is the first air filter.
Since it is removed by the air filter 19, dust does not adhere to the second air filter 23. Therefore, the front panel 26 is removed, the drain pan 25 is removed, and the second
It is almost unnecessary to remove the second air filter 23, which is a troublesome process of pulling out the air filter 23. The increase in the number of steps required for cleaning the second air filter 23 due to the provision of the second air filter 23 need hardly be considered.

The second air filter 23 in the above embodiment cannot be pulled out unless the front panel 26 and the drain pan 25 are removed. However,
The second air filter according to the present invention does not require that the drain pan cannot be pulled out without removing the drain pan, as long as the second air filter cannot be pulled out without removing the front panel. Further, the air filter mounting structure of the air conditioner of the present invention is not limited to the fan coil unit having the structure as shown in FIG. 1, but has the basic structure in which a fan is arranged between the suction port and the heat exchanger. It is applicable to all types of harmony machines.

[0015]

As is apparent from the above, the air filter mounting structure for an air conditioner according to the first aspect of the present invention is arranged between the suction port and the fan at a position where the front panel can be taken out without removing the front panel. The first air filter,
Since the second air filter is provided between the fan and the heat exchanger and cannot be taken out without removing the front panel, when the first air filter is removed by mischief or the like, The dust in the indoor air from the fan is located at a position where it cannot be easily taken out by mischief.
Removed by air filter. Therefore, even if the first air filter is removed, the dust-laden air taken from the room is not directly delivered to the internal equipment such as the heat exchanger installed downstream of the second air filter. That is, according to the present invention, it is possible to extend the period for removing dust from the internal equipment and reduce the cost and man-hours.
