JPS58203329A - Drain discharge device for air conditioner - Google Patents

Abstract

PURPOSE:To solve the problem of overflow of drain into the indoor side of the air conditioner due to one's failure to switch a rotary drain elbow at the time of transportation of the air conditioner or during its use and to facilitate the cleaning of the drain elbow clogged with dust, by a method wherein the substantially L-shaped rotary drain elbow which comprises a connecting section and a discharge section and which is adopted to discharged drain pooled in the air conditioner is provided with an opening at a position opposite the discharge section. CONSTITUTION:The drain elbow 14 is provided with the opening 14b at a position opposite the discharge section 14a thereof. As a result, in case where the discharge section 14a of the drain elbow is kept facing upward for the prevention of its dislocation or damage at the time of transportation, or even when the air conditioner is used without rotating the elbow for switching, the drain flows out from the opening 14b without in any case overflowing toward the indoor side of the air conditioner. Further, in case where the air conditioner is used correctly, the opening 14b is kept facing upward so that the drain flows from the discharge section 14a. In addition, it is not necessary to remove the elbow during transportation and there is no fear of its missing nor it fais to be fixed. Moreover, in case where the elbow 14 is clogged with dust or the like, it is possible to clean it through the opening 14b instead of removing it from a perforated projection 2a of a base plate 2.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides an air conditioner main body with a partition plate that divides the interior into an indoor side and an outdoor side, and drains water from the side wall of the board of the air conditioner main body to the outdoor side. This relates to a drain discharge device for an air conditioner, which has a through-hole for draining and a freely rotatable drain elbow for connecting a drain hose to the through-hole. Drain water to the indoor side due to oats.
The purpose is to eliminate the flow and to facilitate cleaning when the drain elbow is clogged with debris.

Hereinafter, the present invention will be described with reference to the accompanying drawings showing one embodiment thereof.

In the figure, 1 is an air conditioner main body, and a front grill 13 is attached to the front surface of the air conditioner main body. Reference numeral 2 denotes a board constituting the air conditioner body 1, which is provided with a partition plate 3 that divides the inside of the air conditioner body 1 into an indoor side and an outdoor side.
An indoor heat exchanger 11 constituting a well-known refrigeration cycle is disposed on the indoor side, and a compressor 9 and an outdoor heat exchanger 1o are disposed on the outdoor side. The substrate 2 has a second side wall on the outdoor side divided by the partition plate 3.
As shown in the figure, a through-hole protrusion 2a is provided, and a drain elbow 14 to which a drain hose (not shown) is connected is rotatably connected. This drain elbow 14 is
The wooden part 14 and the main body connecting part 38 14C are formed in an oval shape, and an opening 14b is formed at the bent part. Reference numeral 6 denotes an indoor air guider, which together with the indoor fan 6 and the indoor heat exchanger 11 constitutes an indoor ventilation circuit. Reference numeral 4 denotes an outdoor air guider, which together with the fan motor 7, the outdoor fan 8, and the outdoor heat exchanger constitutes an outdoor ventilation circuit. Note that 12 is a water tray of the indoor heat exchanger 11.

In the above configuration, the water condensed in the indoor heat exchanger 1 flows from the lower water tray 12 of the indoor heat exchanger 11 onto the substrate 2, and flows from the through-hole protrusion 2a provided in the substrate 2 to the drain elbow 14. is led to the drain hose via the

However, as shown in FIG. 6, the drain elbow 14 in a conventional air conditioner of this type is only configured in an abbreviated shape with a main body connection portion 14C and a drainage portion 14a, and when transported, the drain elbow 14 as shown in FIG. To prevent dislodgement and damage during transportation, orient the drain part 14a upward, or remove the drain elbow 14 and remove the through-hole protrusion 1a during use.
It was attached to.

Therefore, in the former case, when using the drain elbow 14, the user may forget to rotate the drain elbow 14 and use the drain part 14a with the drain part 14a facing upward. Therefore, drainage is not carried out to the outdoor side, and drain water overflows to the indoor side. There were cases where it started flowing out. In the latter case, the drain elbow 14 was not attached to the air conditioner body 2, so it was sometimes lost during transportation or forgotten to be attached.

Furthermore, when the drain elbow 14 is used for a long period of time, it becomes clogged with dirt and the like, and it is necessary to remove the drain elbow 14 from the through-hole protrusion 1a of the substrate 1 in order to remove the dirt. In order to remove it, the through-hole protrusion 1a and the drain elbow 14 are removed.
The fitting of the main body connecting portion 140 was poor, causing water leakage.

In view of the above-mentioned conventional drawbacks, the present invention provides a drainage section 14 in a drain elbow 14 as shown in FIG. An opening 14b is provided on the opposite side of L.

That is, if the drainage part 14a of the drain elbow 14 is directed upward to prevent it from coming off during transportation and to prevent damage, as shown in FIG. 3, even if you forget to change the rotation of the drain elbow 14 during use. The drainage water flows out through the opening 14b, and indoor hedren water does not overflow. When the device is still in regular use, the opening 14b is left open as shown in FIG. 2, and water flows out from the drainage portion 14a.

Furthermore, there is no need to remove the drain elbow 14 during transportation, and there is no need to lose it or forget to install it.

Furthermore, if the drain elbow 14 is clogged with dirt, it can be cleaned using the opening 14b.
4 from the through-hole protrusion 2a of the substrate 2,
Garbage can be removed.

In addition, the same effect can be expected not only in this embodiment but also in a structure in which a through hole 2b is formed in the substrate 2 and the main body connecting portion 14G of the drain elbow 14 is fitted into the through hole 2b as shown in FIG.

As is clear from the above embodiments, the present invention provides a heat exchanger,
The main body of the air conditioner equipped with a blower is provided with a partition plate that divides the inside of the main body into an indoor side and an outdoor side, and furthermore, on the outdoor side of the air conditioner main body, a partition plate is installed on the side wall of the board to remove the drain water accumulated on the board. An abbreviated drain elbow consisting of a main body connection part and a drainage part for draining water is rotatably provided, and a through hole facing the opening of the drainage part is provided in the connecting part of the main body connection part and the drainage part in this drain elbow. This has various advantages, such as preventing drain water from overflowing indoors due to forgetting to change the rotation of the drain elbow during transportation and use, and making cleaning work easier as the drain elbow can still be cleaned through the through hole. It has the following.
