Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a drain pump mounting device for discharging drain water accumulated in a water tray of an air conditioner.

Conventional technology In recent years, in order to make effective use of living rooms and improve the aesthetics, air conditioners have been recessed into ceilings, closets, etc.
The so-called built-in technology is rapidly progressing. For this reason, it is no longer possible to drain the drain water generated during cooling or dehumidifying operation using a natural head, and a device for forcibly discharging the drain water has become necessary.

Conventionally, this type of drain pump mounting device has been used, for example, as shown in Japanese Utility Model Application Publication No. 160890/1983.
The structure was as shown in Figure 2.

That is, an opening 102 is formed in a part of the main body 101, and a support plate 106 having a drain pump 103, a float switch 104, and a pipe 105 can be attached to and removed from this opening based on the appearance of the main body.

Problems to be Solved by the Invention However, with such a structure, during maintenance and inspection, depending on the structure of the air conditioner installation location, such as the ceiling or closet, the screws of the support plate may not be removed. Another problem is that there is not enough space to take out the drain pump mounting device in the horizontal direction, and furthermore, an opening large enough to take out the drain pump mounting device must be secured in the ceiling or the like. In particular, an opening for attaching and detaching the device requires processing on the ceiling, etc., and depending on the installation environment, it may not be possible to secure the opening.

Therefore, the present invention enables the drain pump mounting device to be taken out from two directions, upper and lower, even if the air conditioner is installed inside a ceiling, a closet, or the like.

Means for Solving the Problems The technical means of the present invention for solving the above-mentioned problems is to provide an air conditioner in which a heat exchange chamber and a ventilation chamber are arranged in the center through a partition plate. A drain pump mounting device is provided, and this mounting device is screwed and fixed to the partition plate from the ventilation chamber side.

With this configuration, for example, when an air conditioner is installed in the ceiling or above a closet, and the drain pump is taken out downward for maintenance or inspection, the bottom plate of the heat exchange room and the water tray are removed from below. This mounting device can be taken out from below the heat exchange chamber by removing the screws, etc. that fixed the drain pump mounting device to the partition plate from below the ventilation chamber. In addition, if the drain pump is installed at the bottom of a closet and is to be taken out upward, remove the top plate of the heat exchange chamber from above, and remove the screws, etc. that fixed the drain pump mounting device to the partition plate from above the ventilation chamber. This allows the drain pump mounting device to be taken out from above the heat exchange chamber.

Embodiment Hereinafter, an embodiment of the present invention will be described based on the accompanying drawings.

In FIG. 1, reference numeral 1 denotes an air conditioner main body, which is composed of a heat exchange chamber 2, a partition plate 3, and a ventilation chamber 4. The heat exchange chamber 2 includes a top plate 5, a bottom plate 6, which are removable from above and below, and a heat exchanger 7 and a water tray 8 for receiving drain water condensed on the heat exchanger 7. . Reference numeral 9 denotes a drain pump for discharging the drain water 10 in the water tray 8, and it is fixed to a mounting device 12 through anti-vibration rubber 11 at its upper and lower parts, and the side surface of the mounting device 12 is connected to the partition plate 3. , is fixed with screws 13 from the ventilation chamber 4 side. The ventilation chamber 4 includes a top plate 14, a bottom plate 15, which are removable from above and below, and a fan 16 and a fan case 1 thereof.
It is equipped with 7.

Next, a case will be described in which the air conditioner main body 1 is installed in the ceiling or in the upper part of a closet, and the drain pump is taken out downward. First, from below,
Remove the bottom plate 15 of the ventilation chamber 4, or remove the screws 6a from the opening serving as the air intake port, and remove the bottom plate 6 and water tray 8 of the heat exchange chamber 2. next,
The drain pump mounting device 12 can be taken out from below the heat exchange chamber 2 by inserting a hand from below the ventilation chamber 4 and removing the screws 13 fixing the drain pump mounting device 12.

Further, a case will be described in which the air conditioner main body 1 is installed at the bottom of a closet or the like and the drain pump is taken out upward. First, remove the top plate 14 of the ventilation chamber 4 from above, or remove the screws 5a from the opening serving as the air intake port, and remove the top plate 5 of the heat exchange chamber 2. Next, by inserting your hand from above the ventilation chamber 4 and removing the screws 13 fixing the drain pump mounting device 12, the drain pump mounting device 12 can be taken out from above the heat exchange chamber.

As described above, according to this embodiment, the drain pump can be removed regardless of whether the air conditioner is installed on the ceiling, the upper part of the closet, or the lower part of the closet.

Effects of the Invention The present invention provides a method for attaching the drain pump to the air conditioner main body by attaching the drain pump to the central partition plate of the air conditioner main body via a mounting member.
Removal can be done from two directions, top and bottom, which alleviates restrictions on where the air conditioner can be installed, and greatly improves service work when replacing the drain pump.
Furthermore, since the direction of attaching and detaching the drain pump is not restricted, there is no need to provide a separate opening for extracting the drain pump on the installation surface such as the ceiling, so the dimensions of decorative grilles, etc. can be minimized, reducing installation space. The transformation is measured.
