Description

  The present invention relates to an indoor unit of an air conditioner, and more specifically, in an air conditioner including a fastening portion that fastens an outer part constituting a main body to a fixing member of a heat exchanger, The present invention relates to a structure provided with condensed water collecting means for guiding condensed water dripping from the surface of the fastening portion to the drain pan.

  When the outer parts (for example, the front panel) of the air conditioner are screwed with the parts to be cooled such as the internal heat exchanger, the head of the screw is cooled, and the outer casing of the air conditioner is dewed. Conventionally, a heat insulating material is attached to the head of the screw to prevent this dew. Or in order to collect the dew which has adhered, the countermeasure which sticks a flocking sheet has been taken.

Moreover, as a conventional dew treatment apparatus for an air conditioner, for example, the one shown in FIGS. 6 and 7 is known (for example, see Utility Model Document 1).
6 to 7, reference numeral 1 ′ denotes a frame that constitutes an indoor unit, and a heat exchanger 2 ′, a water tray 3 ′, and an electrical block 10 ′ are fixed to the frame 1 ′. Further, the heat exchanger 2 ′ is connected to a pipe 5 ′ to a coupling device 4 ′ that constitutes the refrigeration cycle with the outdoor unit. The coupling device 4 ′ is fixed to the fixture 6 ′ with screws or the like, and further fixed to the frame 1 ′ with screws or the like.

The frame 1 'is provided with a mounting portion 7' for a fixture 6 ', and the mounting portion is provided with a hole 8' shown in FIG. 7, which is connected to the rear edge 9 'of the frame 1'. ing.
With the above configuration, when the air conditioner performs the cooling operation, the dew condensation water condensed on the coupling device 4 ′ and the fixture 6 ′ passes through the hole 8 ′ provided in the frame 1 ′, and the rear edge 9 ′. Led to. In addition, the water is guided from the water inlet 9 'to the water tray 3' and discharged out of the air conditioner body.

However, when the above-mentioned heat insulating material is pasted, workability is poor at the time of disassembling services and the like, and the number of parts increases. Moreover, when a flocked sheet is affixed, it drops when the water absorption amount of the flocked sheet is exceeded, and the number of parts increases.
Further, in the case of the utility model document 1, there is a problem that the structure is complicated and the material cost increases.

  In view of the above-described problems, the present invention provides an air conditioner having a fastening portion that fastens outer parts constituting a main body to a side plate of a heat exchanger, and condensation that drops from the surface of the fastening portion to a lower portion of the fastening portion. It aims at providing the air conditioner provided with the dew condensation water collection | recovery means which guides water to the said drain pan.

In order to solve the above-mentioned problems, the present invention is provided with a suction port and a blower outlet in the main body, and a heat exchanger is disposed in an air passage connecting the suction port and the blower outlet, and is generated in the heat exchanger. In an air conditioner provided with a drain pan for collecting dew condensation water, and having a fastening part for fastening an outer part constituting the main body to a fixing member of the heat exchanger,
Condensed water collecting means for guiding the condensed water dripping from the surface of the fastening part to the drain pan is provided at the lower part of the fastening part.

  Moreover, the said dew condensation water collection | recovery means becomes a structure which consists of a drain receptacle formed just under the said fastening part of the front panel which comprises the said main body.

  Further, the dew condensation water collecting means comprises a drain receptacle and a drainage tub provided between the drain receptacle and the drain pan.

  According to the present invention, the dew condensation water generated on the surface of the fastening portion by the cooling of the heat exchanger 5 of the indoor unit 1 during the cooling operation is received by the drain pan 9 and the dew condensation dripped from the drain pan 9 is drain pan. By collecting in 7 and draining to the outside of the indoor unit 1, a screw can be fastened to the cooling portion without adding parts such as a sealing material.
