Description

[Detailed description of the invention] This invention is similar to ceiling-hanging or wall-mounted air conditioners, in which the heat exchange chamber is constructed within a relatively narrow space, and the drain pan is constructed of a heat insulating material such as styrofoam to reduce weight. When arranging this drain pan for an air conditioner, it is possible to securely install the drain pan with a small number of components without shifting.

An embodiment of the present invention will be described below with reference to the accompanying drawings.

In the figure, 1 is the main body of the ceiling-suspended air conditioner, and the top plate (2
), a bottom plate 3, left and right side plates 4, 5, etc., and each constitutes an intake lower with a filter 6 on the rear surface, and an air outlet 10 with a horizontal looper 8 and a grill 9 on the front surface.

The inside of the main body 1 is divided into a ventilation chamber 12 and a heat exchange chamber 13 by a partition plate 11, and a blower 14 with an air outlet facing the partition plate 11 is fixed in the ventilation chamber 12, while a blower 14 is fixed in the heat exchange chamber 13. An evaporator 15 for the cooling cycle and a heater 16 for heating are arranged.

A drain pan 17 is located below the evaporator 15 and the heater 16 to collect dehumidified water, and is integrally formed of polystyrene foam.

To explain the above structure in more detail, the left and right side plates 4 and 5 are connected to a filter frame 18 in which the filter 6 is inserted at the rear, a partition plate 11 at approximately the center, and an upper support plate 19 and a lower support plate 20 at the front. are fixed respectively.

The top plate 2 consists of these left and right side plates 4, 5, a filter frame 18, a partition plate 11. Each is fixed to the upper support plate 19.

In addition, the bottom plate 3 has a front end as a lower support plate 20 and a bottom plate 2 to be described later.
1 through the elastic material 22,
By screwing the rear end to the filter frame 18, it can be detachably attached.

Further, the grill 9 is detachably attached to the front end of the ceiling 2 and the lower support plate 20 with screws.

Next, the installation of the drain pan 17 will be explained.

The drain pan 17 is integrally formed with rising walls 17a and 17b (the left and right sides are not shown) on the front, back, left, and right sides to give it a dish-like shape. The thickest part 1 is shaped like an arc.
7a' and a continuous portion 17a'' with a smaller thickness are formed.

In this drain pan 17, a rear rising wall 17b is fitted into a recess 11a formed integrally with the partition plate 11, and the front rising wall 17b is held between a lower plate 21 and an upper plate 23 fixed to the lower support plate 20. Ru.

That is, the bottom plate 21 has holes 2 formed in the lower support plate 20.
4, 24. Locking pieces 21a, 21a, 2 inserted into 24
1a, a portion in which rising pieces 2lb, 21b, . It is composed of a flat part 21c that supports a portion 172'' and a stepped portion 21d that supports a thinner portion 172''.

The top plate 23 has an overlapping part 23a which overlaps the upper inclined part 20a of the lower support plate 20 and is fixed with a screw 25, an arcuate covering part 23b which covers the rising wall 17a, and a bottom part of the drain pan 17. The extension part 23c extends a predetermined length along the line.

Further, this upper surface plate 23 is formed of a heat-resistant material in order to prevent the deformation of the drain pan 17 due to the heat transmitted to the drain pan 17 of the heater 16.

Therefore, the drain pan 17 is supported by the partition plate 11 at the rear and by the lower plate 21 at the front, while each part 17a'i of the rising wall 17a is supported by attaching the upper plate 23 to the lower support plate 20.
7a'' is held in place and does not shift at all.

The space into which the front end of the bottom plate 3 is inserted is constituted by the horizontal part 20b fixed to the side plates 4 and 5 of the lower support plate 20, the flat part 21c of the bottom plate 21, and the back surface of the stepped part 21d.

As is clear from the above explanation, according to the present invention, large and small parts are provided on the rising wall of the drain pan, and these large and small parts are sandwiched between the upper and lower plates for preventing heat transfer, so that misalignment of the drain pan is prevented. It is completely prevented and securely fixed, and the top plate is for preventing heat transfer, so the parts can be used for multiple purposes.
This can further promote weight reduction.
