Description

[Detailed description of the invention] This invention relates to improving the condensed water treatment structure of an air conditioner, and one of its purposes is to ensure the treatment of condensed water and further reduce the depth dimension of the air conditioner body. It is something.

Hereinafter, the present invention will be described with reference to the accompanying drawings showing one embodiment thereof.

In the figure, reference numeral 1 denotes the indoor unit main body of a separate air conditioner, which is composed of a front grill (not shown) and a board 2. Inside it, as is well known, there is a finch-tube heat exchanger 3 and a blower fan (not shown). (not shown) with ventilation circuit (not shown)
and a water tray 4 disposed at the bottom of the heat exchanger 3.
and the water tray 4 provided at the bottom of the substrate 2.
A main water tray 5 for receiving condensed water flowing down from the main water source, a fan motor 6 for driving the ventilation fan, and a mounting bracket 8 for attaching the fan motor 6 to the side plate 7 constituting the ventilation circuit are provided, respectively. . Here, as is well known, the heat exchanger 3 has a large number of steel pipes passing through the fins and end plates 3a, and a refrigerant passage is formed by connecting each copper pipe with a U-shaped connecting pipe 3a. . Reference numeral 9 denotes a connecting pipe for connecting the refrigerant passage to the refrigeration cycle of the outdoor unit, which extends to the outside of the indoor unit main body 1. 10 is a heat insulating material for covering the connecting pipe 9;
It is provided throughout the area except for the vicinity of the heat exchanger 3.

Reference numeral 11 denotes a thermistor for detecting the temperature of the heat exchanger provided at the upper end of the heat exchanger 3, and a connecting wire 11a
is extending. Reference numeral 12 denotes a cover provided at the side end of the heat exchanger 3, which is integrally formed of a synthetic resin material. This cover 12 includes a main body portion 12a that covers the end plate 3a of the heat exchanger 3, and a main body portion 12a that covers the end plate 3a of the heat exchanger 3.
A lead-out portion 12a is formed at the lower end of the cover 12a and extends into the water tray 4 to guide dew condensation generated inside the cover 12 to the water tray 4; Thermistor cover part 1
2c, an extending covering portion 12d that covers the exposed portion of the connecting pipe 9, and an inclined guide portion 1 that guides the condensed water flowing down the extending covering portion 12d toward the water receiving tray 4 side.
2e, a fixing recess 12f formed approximately at the center of the main body 12a so as to protrude between the U-shaped connecting pipes 3b, and a drainage hole 12g formed in the bottom of the fixing recess 12f. ing. Here, the fixing of the cover 12 is performed by
The inner width of the fixing recess 12f is made slightly smaller than the outer width of the U-shaped connecting tube 3b, and the width of the fixing recess 12f is made slightly larger than the mutual spacing of the U-shaped connecting tube 3b. The flexible deformation force also contributes to the fixing action.

In the above configuration, in the conventional air conditioner of this type, condensation dripping from the end face of the heat exchanger 3 and the connecting pipe 3b routed from the end face can be treated by attaching a cover made of polystyrene foam or the like or a heat insulating material to the end face of the heat exchanger. In addition, a heat insulating material was attached to the connecting pipe 3b, and a metal cover was screwed to the mounting base 8 to prevent water from dripping onto the fan motor 6, so that the water dripped into the water pans 4 and 5.

However, with such a conventional structure, at least three components are required: a cover or heat insulating material for the end face of the heat exchanger, a heat insulating material for the connecting pipes, and a cover to prevent dripping onto the fan motor located below the above components.
This method requires separate parts, which has the drawbacks of high material costs, increased work hours, and unstable quality due to the dispersion of condensed water. Furthermore, the heat exchanger has the disadvantage that it generates squeaking noise during operation due to the difference in expansion coefficient between the cover attached to the heat exchanger and the heat exchanger.

However, in this embodiment, the main body part 12a of the cover 12 prevents the condensed water from scattering on the end plate 3 of the heat exchanger 3 and the U-shaped connecting pipe 3a, and the water receptacle 4 The condensed water in the connecting pipe 9 is guided from the outlet part 12b to the water tray 4 by the extending cover part 12d and the inclined guide part 12e. This structure allows reliable treatment of condensed water. In addition, since the cover 12 is fixed simply by utilizing the flexible deformation of the cover itself, the workability is good, and the fixing recess 12f of the cover 12 is
The condensed water that has formed on the cover 1 also passes through the drain hole 12g.
Since the condensation is guided into the interior of the cover 2, dew condensation on the cover surface is also reliably treated.

Note that if the cover 12 is made of a transparent synthetic resin material, the attachment state of the cover 12 can be checked, and dew condensation water treatment can be performed more reliably.

As is clear from the above embodiments, the condensed water treatment structure of the air conditioner according to the present invention includes a cover that covers the side part of the heat exchanger, a main body part, a lead-out part, an extended cover part,
Consisting of an inclined guide section, this cover can prevent condensation from scattering on the side surface of the heat exchanger, and can also prevent condensed water from scattering from the connecting pipes that extend, ensuring reliable condensed water treatment. Moreover, since only one cover is attached, it has various advantages such as extremely good workability.
