Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mounting structure for a drain hose and a drain connector for discharging drain water out of the main body of an air conditioner.

Conventionally, it has been convenient for construction to install the drain connector in an air conditioner close to the refrigerant piping extraction part, so it has been installed between a part of the main body, such as between the bottom plate and the pipe port cover. It is fixed like this.

An example of this is explained in Fig. 5. A is a bottom plate that constitutes a part of the air conditioner main body, b is a pipe port cover that forms an insertion port d for a refrigerant pipe C, and a screw e is attached to the bottom plate. It is fixed at a.

f is a drain connector with a drain hose g connected to one side by a connecting ring h, which is interposed between the bottom plate a and the cover b, and whose mounting flange f' is connected to the bottom plate a and the pipe port cover b by screws i, respectively. , i.

With this configuration, in order to remove cover b during piping work, it is necessary to remove screws i and i of mounting flange f', which makes work difficult. Increase in points 9Increase in work hours,
It was extremely inconvenient.

The present invention was developed with the aim of solving these drawbacks, and one embodiment thereof will be described below with reference to the accompanying drawings.

In the figure, 1 is an indoor unit of a ceiling-suspended air conditioner equipped with an indoor coil, a fan (none of which are shown), etc., with a top plate 2, a bottom plate 3, and the sides of both plates 2 and 3 bent. A cabinet is constituted by a side plate 5 connecting the edges 2a, 3a with screws 4, 4, and a suction lower with a filter 6 provided at the rear, and a conditioned air outlet 8 at the front.

Reference numeral 9 denotes a piping space located between the suction lower and the air outlet 8 and facing the side plate 5, which includes a partition plate 10 that partitions a room in which indoor coils, fans, etc. are arranged, and piping connected to the coils. It is divided by a partition plate 12 provided with connection ports 11 and 11'.

Reference numeral 13 designates a part of a drain pan that collects dew water from the coil, and extends into the piping space 9 from the lower end of the partition plate 12.

A pipe port cover 14 is provided at the rear of the indoor unit 1 adjacent to the suction lower and facing the pipe space 9, through which refrigerant pipes 15 and 15' connected to the pipe connection ports 11° and 11' are inserted. The insertion port 16 and the drain pan 13 form a support port 19 that supports a drain connector 18 connected to the drain hose 17.

This piping port cover 14 is divided into two in the vertical direction so that the insertion port 16 and the support port 19 are divided approximately at the center.

On the other hand, 14a is adjacent to the suction lower, and has a top plate 2 and a bottom plate 3.
It is fixed in advance to the rear bent edges 2b and 3b with screws 20 and 20, and an insertion opening portion 16a and a support portion 19a forming a support opening are formed.

The other side 14b consists of a side 14b' having an insertion opening part 16b, a support part 19b forming a support opening, and the other side 14b'' having holes 4', 4' for the screws 4, 4. '' is the double-folded edge 2a.

2b and inserted between 3a and 3b and the side bent edge 2
It is fixed to a and 3 a with screws 21 and 21.

That is, the other cover 14b is detachably attached to the one cover 14a by removing the side plate 5 and removing the screws 21, 21.

On the other hand, a drain connector 1 is also attached to the rear bent edge 3b of the bottom plate 3.
A semicircular support part 19C that supports the lower part of the support part 8 projects inwardly, and when the double force bar 141.14b is combined between the bottom plate 3 and the top plate 2, the insertion port 16 and the support port 1
9 is made up of.

Incidentally, the drain hose 17 has a flexible jacket 17a.

It is constructed by filling a heat insulating material 17C between inner sheaths 17b, and is fitted to one side of the drain connector 18, and this overlapping portion serves as support parts 19a, 19b, 19C.
These support parts 19 a , 19 b , 1
Claw portions 19a', 19b', and 19C' that bite into the drain hose 17 are formed at the tips of 9C, respectively.

Therefore, the drain hose 17 and the retainer 18 do not require a separate fastening band or the like, and the drain connector 18 can be fixed to the pipe port cover 14 and the bottom plate 3 without being screwed. There is.

In addition, in the above embodiment, the claw portions 19 a', 19 b',
19C' is each support part 19a, 19b, 19
C, but the piping port covers 14 a and 14 b
(7) Almost the same effect can be obtained even if the claws are formed only on the support parts 19a and 19b, and if the fitting state between the drain hose 17 and the connector 18 is sufficiently strong, the claw parts 19a ', 19 b', 19C' to drain connector 18
It may be made to bite into itself.

As is clear from the above description, the air conditioner of the present invention includes a support part that supports one side of the drain connector connected to the drain hose on the bent edge of the bottom plate that constitutes the air conditioner main body. At the same time, a support portion for supporting the other side of the drain connector is formed on the pipe port cover that is detachably fixed to the bent edge, and a claw portion that bites into the drain connector or the drain hose is provided at the tip of the support portion. Because it forms a This has various effects such as being able to omit parts for fixing.
