Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a ceiling-mounted air conditioner equipped with a drain pan.

BACKGROUND ART Conventionally, a ceiling-embedded air conditioner for equipment such as a fan coil unit has a configuration as shown in FIGS. 3 and 4. That is, the main body 4 of the ceiling-embedded air conditioner is suspended in the ceiling 3,
Its lower part faces the opening 2 of the ceiling surface 1, and a grill 7 having an inlet 5 and an outlet 6 formed therein is fixed from below to the lower surface of the main body 4. Inside the main body 4, there are provided a blower 8, a heat exchanger 9 for passing cold and hot water, and a drain pan 11 fixed to left and right set plates (not shown) below the heat exchanger 9. The blower 8 is fixed to a blower mounting plate 12 provided vertically. Further, the drain pan 11 was formed into a box shape and was provided with an inclination, and a connecting pipe 13 for connecting to a drain hose (not shown) was fixed to one side by welding 14. .

Problems to be Solved by the Invention In such a conventional configuration, there was a problem in that the blower 8, the blower mounting plate 12, and the drain pan 11 were each constructed as separate parts, which increased the number of manufacturing steps.

This invention solves these problems,
The object of the present invention is to provide a ceiling-embedded air conditioner that has a small number of parts, requires a small number of assembly steps, and can reduce manufacturing costs.

Means for Solving the Problem In order to solve this problem, the present invention includes a blower provided opposite to the heat exchanger, and a blower mounting plate to which the blower is fixed. The lower part extends below the heat exchanger and is formed into a substantially V shape, and is provided with a drain receiving part formed to be inclined to one side with respect to the longitudinal direction of the heat exchanger. It is.

Function: With this configuration, drain water dripping from the heat exchanger is received by the drain receiver integrated with the blower mounting plate, and drained by flowing in a lower sloped direction.

Embodiment An embodiment of the present invention is shown below in Figs. 1 and 2.
This will be explained based on the diagram. In the figure, reference numeral 20 denotes the main body of the ceiling-embedded air conditioner, which is suspended from above the ceiling 19, with its lower part facing the opening 18 in the ceiling surface 17. A grill 23 having an inlet 21 and an outlet 22 is fixed to the lower surface of the main body 20. Inside the main body 20, there is provided a blower 24 consisting of a casing, blades, and an electric motor (all not shown), and a blower mounting plate 25 to which the blower 24 is fixed. This blower mounting plate 25
is provided facing the heat exchanger 26 through which cold and hot water flows, and has a discharge port 27 corresponding to the blower 24 in the vertical part, and a drain receiver extending downward and formed into a substantially V shape on the lower side. The portion 28 is formed by press working or the like. The drain receiving part 28 is provided below the heat exchanger 26, and the drain receiving part 28 is bent and inclined with a slope 29 on one side with respect to the longitudinal direction of the heat exchanger 26. A connecting pipe 30 for connecting to a drain hose (not shown) is fixed by welding 31 to the lower side. i.e. connection pipe 3
A part of the upper end surface of the drain receiving part 28 is cut out in a V-shape, is applied from below the drain receiving part 28, and is fixed by welding 31 partially. Note that 32 in the figure is a sleeve.

In the above configuration, by operating the blower 24, the air flowing in from the suction port 21 is transferred to the blower 24.
The air passes through the heat exchanger 26 through the outlet 27 of No. 4, and is blown into the room through the outlet 22 as cold or warm air. In this air flow path, during cooling, dew condenses on the heat exchanger 26 through which cold water is passed, but this condensed drain water drips onto the drain receiver 28 that is integrated with the blower mounting plate 25, and flows through the lower inclined connection. It flows to the pipe 30 side and is drained.

Effects of the invention As is clear from the above embodiments, the present invention extends the lower part of the blower mounting plate to the lower part of the heat exchanger and
By forming the drain receiving part in a letter shape and slanting to one side, it is integrated.
There is no need to construct the blower mounting plate and the drain pan as separate parts as in the past, and the blower mounting plate with the drain receiving part can be completed in one process by press working, thus making it easier to manufacture. This has the effect of significantly reducing the number of man-hours and reducing costs.
