Abstract

PROBLEM TO BE SOLVED: To eliminate the need of increasing the size of an apparatus body even when a filter and a condensate pan are disposed below a heat exchanger. SOLUTION: As condensate in a heat exchanger 3 drops from the heat exchanger 3, condensate dropping on the side of a drain pan 5 is received directly by the drain pan 5. Condensate dropping on the side of a filter 2 drops on each slanting plate 6 and is guided to the drain pan 5 along each slanting plate 6. Accordingly, the drain pan 5 can be more reduced than the lower surface of the heat exchanger 3, and hence the filter 2 can be accommodated in a surface where the drain pan 5 is not existent.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner for cooling a general house or office building.

[0002]

2. Description of the Related Art Conventionally, a device body having a small depth dimension, such as a fan coil unit, is provided.
It is known that air sucked from an air inlet provided in the lower part of the device body is cooled by a heat exchanger that circulates a refrigerant gas or cold water, and the cooled air is discharged from the upper part of the device body. In this case, a filter is provided at the air intake port of the main body of the apparatus, and the dust in the intake air is captured by this filter. Further, a drain pan is provided below the heat exchanger so that the drain pan receives the condensed water dropped from the heat exchanger.

[0003]

However, since the drain pan receives the condensed water dripping from the heat exchanger,
Since the width and depth dimensions are larger than that of the heat exchanger, when the air intake port is provided on the lower surface of the main body of the device and the filter is arranged below the drain pan, at least a gap that allows air to flow before and after the drain pan. Therefore, there is a problem that the depth dimension of the main body of the apparatus is increased due to this. Also, when the air intake port is provided on the front surface of the device body and the filter is arranged between the heat exchanger and the drain pan, the filter should be moved vertically to the front side of the device body to prevent condensed water from adhering to it. However, there is a problem in that the height of the main body of the apparatus must be increased.

The present invention has been made in view of the above problems, and an object thereof is to increase the size of the apparatus main body even when the filter and the condensed water receiver are arranged below the heat exchanger. It is to provide an air conditioner that does not exist.

[0005]

In order to achieve the above object, the present invention provides, in claim 1, a filter facing an air intake port provided in a lower portion of an apparatus main body, and cooling air sucked into the apparatus main body. In the air conditioner having a heat exchanger for receiving condensed water dropped from the heat exchanger, a filter and a condensed water receiver are provided below the heat exchanger in the front-back direction of the device main body. And a ventilation member for guiding condensed water dropped from the heat exchanger to the condensed water receiver around the filter. As a result, the condensed water dropped on the condensed water receiver side is directly received by the condensed water receiver, and the condensed water dropped on the filter side falls on the guide member and is guided by the guide member and received by the condensed water receiver. Therefore, the condensed water receiver can be made smaller than the lower surface of the heat exchanger, and the filter can be housed in the space where the condensed water receiver does not exist.

According to a second aspect of the present invention, in the air conditioner according to the first aspect, the guide member is formed by a plurality of inclined plates which are inclined downwardly toward the condensed water receiver side. . As a result, in addition to the effect of the first aspect, the condensed water that has fallen on each inclined plate is guided to the condensed water receiver along each inclined plate, and the intake air flows between each inclined plate.
