Description

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

BACKGROUND ART Conventionally, the drain pan of an air conditioner such as a fan coil unit has been constructed as shown in FIGS. 5 and 6. That is, a heat exchanger 4 and a drain pan 10 are provided above the exterior of the main body 1, a blower 5 is arranged below them, and frame side plates 6 and 7 that sandwich these from both sides and are fixed at their respective positions are attached to the main body. It is fixed at 1. This drain pan 10
are inserted into the notches 8 and 9 of the frame side plate 6, and a shielding plate 13 is attached to the rear plate of the main body 1 with screws 14 to prevent it from coming off, but the heat exchanger 4
It is necessary to have a certain inclination in the longitudinal direction for the function of receiving and collecting the drain and flowing it out of the main body 1, so a gasket 12 serving as a spacer is applied to the bottom surface on the side of the notch 9 and lifted and tilted. 11 is drain pan 1
15 is a floor surface on which the main body 1 is installed.

Problems to be Solved by the Invention In such a configuration, the slope slopes downward from the side plate 7 toward the side plate 6, and normally it does not shift toward the side plate 6 due to the retaining piece 11. Main body 1
When the main body 1 is installed on the floor 15, for example, if the floor 15 is tilted in the opposite direction to the tilt of the drain pan 10, the drain pan 10 approaches the horizontal direction and can be moved toward the stopper 11, and the drain pan 10 rattles occur. Furthermore, since the drain pan 10 is installed at an angle, openings for inserting the drain pan 10 must be made large in the side plates 6 and 7 to facilitate installation. The problem was that the installation was unstable, and air leaked through the gaps, resulting in poor efficiency.

The present invention is intended to solve these problems, and aims to eliminate rattling of the drain pan, ensure stable installation, and ensure reliable drainage.

Means for Solving the Problem In order to solve this problem, the present invention has a frame side plate provided on both the left and right sides of the main body with an opening for inserting a drain pan, and a heat exchanger supported by the frame side plate. an exchanger, and a drain pan located below the heat exchanger, the bottom of which is formed in a substantially V shape, and supported at an angle by the side plate of the frame, the upper side of which is approximately parallel to the bottom of the drain pan. The higher end of the drain pan is pressed against the frame side plate so as to be lifted from below by a retaining plate that is V-shaped and has a substantially U-shaped lower side along the inner surface of the drain pan, and the lower end The end portion is pressed against the frame side plate from above.

Function With this configuration, one side uses the holding plate to push the drain pan upward to cover the opening of the frame side plate, and the other side uses the holding plate to push down the inside of the drain pan from above and fix it so that it tilts downward. However, the opening of the other frame side plate is substantially covered by the holding plate.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 to 4. A main body 16 of an air conditioner such as a fan coil unit is composed of an exterior top plate 17 and side plates 18 and 19. The main body 16 is provided with a heat exchanger 20 for passing cold and hot water upward, and a blower 40 below. Below the heat exchanger 20, a drain pan 23 for receiving drain water is provided at an angle. This drain pan 23 is the main body 16
One frame side plate 25 is provided at an angle between frame side plates 24 and 25 provided within the frame.
The side is pushed up from below and held by a holding plate 26 fixed with screws 27. The other side of the frame side plate 24 is fixed with screws 29,
The inside is pressed down and held by a presser plate 28 pushed down from above. Drain pan 23
As shown in Figure 4, one side is the drain drainage part 3.
A stop plate 30 is provided on the other side to stop the flow of drain water, and a notch 23a that is fitted into the frame side plate 25 is provided on the other side. Further, the bottom portion 32 of the drain pan 23 is formed in a substantially V shape. As shown in FIG. 2, the holding plate 26 has an upper end 26a shaped to fit the outside of the bottom 32 of the drain pan 23, and a lower end 26a.
6b has a substantially U-shape that almost fits inside the inner bottom portion 32 of the drain pan 23.

Note that the holding plate 26 and the pressing plate 28 have the same shape.

In the above configuration, during cooling, condensate condensed on the heat exchanger 20 falls into the drain pan 23 and flows from the drain drainage section 31 to the saucer 33 to be drained. When installing the drain pan 23, make sure to
1 on the saucer 33 side, insert it deeply from the front toward the piping space A through the opening 35 of the frame side plate 24 while holding it horizontally and diagonally, and then insert the stop plate 3
Insert the end on the 0 side into the opening 34 of the frame side plate 25, and then fit the notch 23a of the drain pan 23 into the frame side plate 25 above the opening 34 to allow left and right movement and forward and backward movement. to stop. Then, on the side of the frame side plate 25, the upper end 26a of the holding plate 26 is applied from below and pushed upward and fixed with the screw 27. By this fixing, the opening 34 of the frame side plate 25 is covered. Next, on the frame side plate 24 side, press the presser plate 2
8 into the inside of the substantially V-shaped bottom part 32 from above and fixed with a screw 29. The opening 35 is covered by this fixation.

As a result, the openings 34 and 35 provided in the frame side plates 24 and 25 can be made larger, and therefore the slope of the drain pan 23 can also be increased, and the floor 36 can be sloped and uneven. Even these slopes can be absorbed and the drain will flow reliably.

Effects of the invention As described above, the present invention provides a large opening in the frame side plate into which the drain pan enters, and on one side is fixed by pushing upward from below on the outside of the frame side plate with a retaining plate, thereby shielding the frame side plate opening. At the same time, on the other side, the inside of the drain pan is held down and fixed by a holding plate, so the rattling of the drain pan is eliminated.
It is a stable installation method, the slope of the drain pan can be set sufficiently large, and even if there is a slight slope of the floor surface, the slope of the drain pan can be obtained to absorb it. It can be reliably shielded by the holding plate and presser plate that fix it. Furthermore, the holding plate and the presser plate may have the same shape, so that they can be made into common parts.
