Description
The present invention relates to an indoor unit of an air conditioner.
In general, an air conditioner is a cooling / heating system for cooling or heating a city by an operation of sucking indoor air and exchanging heat with coolant of low or high temperature and discharging it to the room, And a valve-evaporator.
Particularly, the air conditioner mainly comprises an outdoor unit (also referred to as an 'outdoor side' or a 'heat radiating side') installed in an outdoor space and an indoor unit (also referred to as an 'indoor side' or ' A condenser (outdoor heat exchanger) and a compressor are installed in the outdoor unit, and an evaporator is installed in the indoor unit (indoor heat exchanger).
As is well known, the air conditioner can be broadly divided into a separate type air conditioner in which an outdoor unit and an indoor unit are separated from each other, and an integral type air conditioner in which an outdoor unit and an indoor unit are integrally installed. In consideration of installation space and noise, Harmonics are preferred.
In the multi-type air conditioner of the separate type air conditioner, a plurality of indoor units are connected to one outdoor unit, and the indoor units are installed in the room for air conditioning, thereby providing a plurality of air conditioners.
Among indoor units of the multi-type air conditioner, indoor units of a cassette type air conditioner installed in the ceiling of the indoor space for cooling and heating the indoor space are widely used.
A typical structure of such a cassette type air conditioner is disclosed in Korean Patent Publication No. 10-2014-079108.
1 and 2 of Korean Patent Laid-Open Publication No. 10-2014-079108, there is provided a condensate pump for pumping condensate into the inside of a main body installed in a ceiling to discharge the condensate to the outside, The mounting portion is protruded inward and then protruded to have a predetermined height so as to be in contact with the drain.
However, in such a structure, in order to support the condensate pump, the mounting portion is protruded into the space inside the main body by a cross-sectional area corresponding to the area of the lower surface of the condensate pump. Therefore, air flowing along the wall surface of the inside of the main body when the air is blown by the blowing fan hits the mount portion, and the increase of the flow resistance due to the air causes a decrease in flow rate and noise.
It is an object of the present invention to provide an indoor unit of an air conditioner which can provide a support structure of a condensate pump provided on a flow path inside a cabinet and at the same time reduce a flow path resistance inside a cabinet, .
An indoor unit of an air conditioner according to an embodiment of the present invention includes: an out plate that forms an outer appearance of a cabinet having a bottom opened; An inner case forming an inner surface of the out plate and formed of a heat insulating material; A blowing fan provided in an inner space of the inner case; A heat exchanger formed around the blower fan and spaced apart from the inner side of the inner case; A panel having a suction port for shielding the cabinet and sucking indoor air, and a discharge port for discharging the heat-exchanged air; A drain pan assembly disposed between the panel and the heat exchanger and collecting the condensed water generated in the heat exchanger; A condensate pump provided in the inner space of the inner case for sucking and discharging the condensed water collected in the drain pan assembly; A mounting portion protruding along an inner side edge of the inner case so as to have a width smaller than a bottom width of the condensate pump; And a supporter portion mounted on an upper end of the mounting portion and on which the condensed water pump is mounted, the mounting portion having a first side protruding along one side of the inner case and a second side protruding along the upper side other than the first side And a second side facing the first side to form an edge of the inner case, wherein the supporter portion is connected across the first side and the second side so that the condensate pump is mounted Wherein a portion of the circumference of the supporter portion is formed in a shape corresponding to an edge of the inner case and is in close contact with an edge of the inner case and the other portion is protruded in a direction opposite to the edge of the inner case, It is possible to extend outwardly to provide a mounting surface of the condensate pump.
The side ends forming the ends of the first side surface and the second side surface can be formed to have a round shape to facilitate the flow of air.
The mounting portion can be formed integrally with the inner case.
The mounting portion is formed of a material different from that of the inner case, and can be fixedly mounted on the inner side of the inner case.
The upper surface of the mounting portion is provided with a mounting bracket formed of a metal or a plastic material. The mounting bracket is bent so as to be press-fit on the upper surface of the first side surface and the second side surface, Holes can be formed.
The supporter is capable of receiving the entire lower surface of the condensate pump.
The supporter is provided with a seating portion protruding upward and separating the condensed water pump, and an opening can be formed in the supporter below the condensed water pump.
It is possible to form a rim along the outer side of the supporter and around the opening and further to form a reinforcing rib that connects between the outer side of the supporter and the rim of the opening.
And a guide portion extending downward from the lower surface of the supporter and closely contacting the inner circumference of the first side surface and the second side surface to guide a mounting position of the supporter.
At least one of the seating portions may be located in a part of the supporter protruding in a direction opposite to the inner side edge of the inner case.

According to the present invention having the above-described configuration, the following effects can be expected.
First, the protrusion of the mounting portion for supporting the condensed water pump can be minimized, so that the flow resistance can be reduced and the flow rate can be increased and the noise can be reduced.
Secondly, by providing a supporter across the mounting portion on the upper surface of the mounting portion, it is possible to stably support the condensate pump while narrowing the protruding portion of the mounting portion.
Thirdly, by adding a mounting bracket to the mounting portion formed of a heat insulating material and having a reduced strength, it is possible to provide a stable mounting structure while reducing a fixing portion with the condensed water pump.
