Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a dew treatment device for an air conditioner.

BACKGROUND ART Conventionally, this type of dew treatment apparatus has been constructed as shown in FIG. That is, the structure is such that condensed water condensed on a fixture 11 of the coupling device is guided to a water receiving tray 13 on the indoor side through a pipe 12 fixed to the fixture by welding or the like, and the condensed water is disposed of.

Problems to be Solved by the Invention However, with such a structure, in addition to the fixture 11 of the coupling device, a pipe 12 made of sheet metal is required, and since the pipe 12 is made of sheet metal, the pipe 12 is Because dew condensation occurs on itself, the tube 12 must be insulated with a heat insulating material or the like, and since the tube 12 is located close to the electrical block, there is a problem of condensed water adhering to the electrical block. Ta.

In other words, it constitutes an indoor unit a of the air conditioner. Since the underframe b is made of sheet metal, it is difficult to construct a complicated flow channel.

Means for Solving the Problems The technical means of the present invention for solving the above problems is to make the underframe that constitutes the indoor unit of the air conditioner made of synthetic resin, thereby preventing condensation on the coupling device and fixtures. The condensed water is treated by guiding the condensed water to a flow channel provided on the back side of the underframe and further to a water tray built into the indoor unit.

Effects The effects of this technical means are as follows.

In other words, when the air conditioner is operated for cooling, the coupling device and the fixtures fixing the coupling device are cooled and dew condenses on them, but this condensed water is guided to the back of the synthetic resin frame and is transferred to the indoor unit. By directing water to the built-in water tray, there is no need for a separate water tank as in the past, and since it is directed to the back of the underframe, there is no fear of condensed water adhering to the electrical equipment block, allowing safe operation.

Embodiment Hereinafter, an embodiment of the present invention will be described based on the accompanying drawings. In Figures 1 to 3, reference numeral 1 denotes a frame made of synthetic resin that constitutes indoor unit A;
A heat exchanger 2, a water tray 3, and an electrical equipment block 10 are fixed to this underframe 1. Furthermore, a pipe 5 is connected from the heat exchanger 2 to a coupling device (flare connector, one-shot coupling) 4 for constructing a refrigeration cycle with an outdoor unit. The coupling device 4 is fixed to the fixture 6 with screws or the like, and further fixed to the underframe 1 with screws or the like. On the underframe 1,
A mounting part 7 of the fixture 6 is provided, and the mounting part is provided with a hole 8 shown in FIG.
It is connected to the groove 9 on the back of the. The size of the hole 8 and the width and depth of the gutter 9 must be changed depending on the amount of dehumidification of the air conditioner.

With the above configuration, when the air conditioner performs cooling operation, the condensed water that has condensed on the coupling device 4 and the fixture 6 passes through the hole 8 provided in the underframe 1 from the fixture and into the hole on the back side. Guided by 9. Further, the water passes through the gutter 9 on the back, is guided to the water tray 3, and is discharged outside the air conditioner main body.

Effects of the invention This invention fixes a sheet metal fixture to a synthetic resin underframe to treat dew condensation during cooling operation, and does not require the use of other parts for dew condensation water treatment. It also has various effects such as complete dew treatment.
