Abstract

PURPOSE:To provide a slight stress applied to a connection part between a drain pipe connection tube and a front side plate and further prevent a damage of the drain pipe even if a slight force is applied to the drain pipe by a method wherein a front side fixing piece is disposed outside a part constituting a side plate of a dew pan and a rear fixing piece is disposed at a front outside plate and a rear outside plate, a drain pipe connection tube passed over the front side plate and the front inner plate is arranged, the drain pipe connection tube is passed through a through-pass port and fixed to the drain pipe connection tube by a seal part. CONSTITUTION:When a drain pipe 65 is connected to a pipe connection tube 62, the drain pipe 65 is moved forwardly, rearwardly, rightwardly and leftwardly with a connection tool or the like, resulting in that a certain stress is applied to a seal part 67 of a through-pass port 66 of the front side outer plate 56 at first around a fulcrum point of the through-pass hole 66. However, the front outside plate 56 and the front side fixing piece 59 are made integral to each other and the front side fixing piece 59 is fastened and fixed to a bottom part 63a of a main body 68 with a screw 65a, so that a stress is almost accommodated at the through-pass hole 64 and the front outer side plate 56 and a stress is hardly applied to the front inner plate 52.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a dew pan for an air conditioner (hereinafter referred to as an air conditioner) installed in the attic of a house.

BACKGROUND OF THE INVENTION In recent years, there has been an increasing demand for preventing water leakage from the seal portion of the drain pan and the drain pipe connection pipe.

The structure of the condensation tray of a conventional air conditioner of this type will be explained with reference to FIGS. 3 and 4. As shown in the figure,
A main body 2 of the air conditioner is suspended in the attic 1 by a slab or the like, an air duct 3 is connected to the front plate 10 of the main body 2, and a suction duct 4 is connected to the rear plate 11. The air blower 5 inside the main body 2 sucks in indoor air, and the cold air cooled by the cooling heat exchanger 6 inside the main body 2 is blown into the room through the blow-off duct 3 to perform air conditioning. At this time, water droplets condensed on the surface of the heat exchanger 6 during cooling operation are collected in a dew pan 7 made of resin and provided below the cooling heat exchanger 6, and drained into a drain provided in the dew pan 7. It is discharged from the piping connection pipe 8 via the drain piping 9. The drain pipe connection pipe 8 passes through the penetration hole 13 of the front plate 10 and is fixed to the front side plate 14 of the dew pan 7.
A seal part 15 made of silicone is firmly sealed to prevent water leakage, and the drain pipe 9 is connected to the seal part 15.

In this way, conventionally, the drain piping connection pipe 8 and the dew pan 7
The fixation was such that the front side plate 14 and the end of the drain pipe connection pipe 8 were connected with an adhesive.

Problems to be Solved by the Invention In such a conventional air conditioner dew pan, when performing drain piping work, the drain piping connection pipe 8 and the drain piping 9 are connected, and the drain piping 9 is arranged in the ceiling 1. During construction, the drain piping 9 may be moved horizontally or vertically, and the stress caused by this may cause the front plate 1 of the main body 2 to move.
Using the through hole 13 of No. 0 as a fulcrum, stress is applied to the joint between the front side plate 14 of the surface condensation pan 7 and the drain pipe connection pipe 8, and if the stress is large, the joint seal 15 will be destroyed, and the condensation pan There was a problem that the water collected in 7 was leaking.

The present invention solves the above-mentioned problems by minimizing the stress applied to the joint between the drain piping connection pipe and the front side plate, so that even if some force is applied to the drain piping during drain piping construction, it will not break. It is an object of the present invention to provide a dew pan device that does not require any dew condensation.

Means for Solving the Problems In order to achieve the above object, the present invention includes a dew pan provided inside the main body below the heat exchanger, and this dew pan is bent from the front inner plate toward the outer panel. , a front-inverted outer plate having a front attachment piece for fixing to the bottom; a rear outer plate bent outward from the rear inner plate and having a rear attachment piece for fixing to the bottom; Both stools are provided with an exposed portion consisting of a left side plate and a right side plate, through holes are provided in the front inner plate and the front outer plate, and a through hole is provided in the front plate of the main body, and the through hole and the through hole are provided with a through hole in the front plate of the main body. The structure is such that a drain pipe connection pipe is inserted and a seal portion is applied to the through hole.

According to the above-described structure, the drain pipe connecting pipe is inserted into the through hole provided between the front inner panel and the front outer panel, a sealing part is formed with a sealant, and the front outer panel and the rear outer panel are connected to each other. Each mounting piece provided on the front panel is fixed to the bottom to form a double seal, so that the stress when connecting the drain pipe is absorbed by the front outer plate, and most of the stress is applied to the seal part of the front inner plate. This will prevent the seal from breaking.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 and 2. As shown in the figure, the dew pan 51 provided below the heat exchanger 50 includes a front inner plate 52, a rear inner plate 53, a flat left side plate 54, and a right side plate 55 in the longitudinal direction. A front outer plate 56 is provided so that the front inner plate in the longitudinal direction is folded back to the outside, and a rear outer plate 58 is provided so that the rear inner plate 53 is folded back to the outside. The front outer plate 5
6 includes a front mounting piece 59 having a mounting hole 61 for fixing to the bottom 63g of the main body, and a rear mounting piece 60 having a mounting hole for fixing to the bottom 63a of the rear outer plate 58g5. and fixed with screws 65a. On the other hand, a through hole 66 is provided that extends through the front inner plate 52 and the front outer cover plate 56, and the drain piping connection vibro 2 is inserted into the through hole 66 to form a sealing portion 67 made of silicon.
Then, the drain pipe connecting vibro 2 and the dew pan 51 are fixed by shielding by resin welding. The dew pan 51 is provided on the front plate 63 of the main body 68, and is inserted through the drain pipe connecting vibro 2 into the through hole 64 which is mostly fitted, and is attached to the drain connecting vibro 2.
is connected to the drain pipe 65.

In the above configuration, when the drain pipe 65 is connected to the drain pipe connecting vibro 2, when the drain pipe 65 is moved left and right and back and forth by the connecting blade etc. Stress is applied to the seal portion 67 of the through hole 66 of the main body 68, but this stress is absorbed by the front outer plate 56 and the front mounting piece 59, which are integrated, and the front mounting piece 59 is screwed onto the bottom 63a of the main body 68. 65
Since it is tightened and fixed at point a, the stress is applied to the front outer plate 5.
6 and does not reach the front inner plate 52. In other words, most of the stress applied from the outside by the drain pipe 65 is absorbed by the through hole 64 and the front-inverted outer plate 56, and the front inner plate is hardly subjected to stress, especially on the front side. The seal portion 67 of the inner plate 52 is not affected at all.

Effects of the Invention As is clear from the description of the embodiments described above, the present invention has a front outer plate and a rear plate that are bent outwardly in substantially parallel to the side plate of the dew pan. A front mounting piece and a rear mounting piece are provided on the outer plate, a drain piping connecting pipe is provided that penetrates the front outer plate and the front inner plate, and the drain piping connecting pipe is passed through the through hole to seal the seal part by resin welding. Since the drain piping connecting pipe is fixed in place, even if stress is applied to the front outer plate from the drain piping through the drain piping connecting pipe during drain piping work, the through hole on the main body side will remain in the fitted state. Therefore, the stress applied to the connection part of the drain pipe connection pipe is absorbed by this through hole and the seal part of the front inner plate, and the stress applied to the seal part of the front inner plate is almost negligible, and the stress applied to the seal part of the front inner plate is absorbed. This has the effect that the leakage of water collected in the dew pan is eliminated, and accidents such as staining the ceiling surface are also eliminated.
