Abstract

PURPOSE:To prevent a decrease in efficiency of heat exchanging operation by a method wherein an outdoor water receptacle having condensed water feeding plate is fixed on a base plate between the heat exchanger and a propellor air guiding unit. CONSTITUTION:A plurality of water feeding plates 12 are integrally formed with the bottom part of an outdoor water receptacle 8 and after the water is guided through a water scraping part of a slinger ring, it is formed as a curve to face toward the heat exchanger 9 in a gradual manner. With this arrangement, the condensed water scraped by the slinger ring is dispersed and the concentration of the condensed water at one point in the heat exchanger 9 is prevented and then the water is dispersed and applied over the heat exchanger 9. Therefore, it is possible to prevent a decrease in efficiency of heat exchanging operation.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a device for preventing scattering of condensed water when drain water collected in a drain pan of an air conditioner is scooped up by a slinger ring.

Conventional configuration and problems Generally speaking, this type of drain water treatment equipment uses a slinger ring attached to the outer circumference of a propeller fan for cooling the condenser to collect drain water collected in a drain pan inside a window-type room cooler. The structure that involves rolling and rolling is responsible for the large water droplets that are stirred up by the slinger ring and blown into the condenser, and the largest amount of condensed water is stirred up in section A as shown in Figure 3, which is affected by the wind. It passes between the heat exchangers without receiving much water, and if it passes through the louvers of the outer box, it drips onto the walls and concrete below.

Therefore, there were problems such as the walls getting wet and rotting, and passersby getting hit by them. In addition, as a conventional countermeasure, as shown in Fig. 4, there is a configuration in which a plate C is provided between the heat exchanger a and the propeller fan b to guide the condensed water. This causes problems such as a decrease in air volume and a decrease in heat exchange efficiency.

Purpose of the Invention The present invention eliminates the above-mentioned conventional drawbacks, and one of its objectives is to prevent the scattering of condensed water due to slinger ring and the reduction in heat exchange efficiency by ensuring a sufficient space between the heat exchanger and the propeller fan. It is a solid one.

Structure of the Invention To achieve this object, the present invention provides an outdoor water tray with a condensed water introduction plate mounted on a base plate between the heat exchanger and the propeller air guider.

DESCRIPTION OF THE EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 and 2 of the accompanying drawings.

In FIG. 1, reference numeral 1 denotes a window-type air conditioner main body, the interior of which is partitioned into an indoor side 2 and an outdoor side 3.

Here, since the indoor side 2 has a well-known structure, a description thereof will be omitted. And a propeller fan 6 driven by the outdoor side 3
and an air guider 10 and a compressor 5 are provided, respectively.

11 is a drain pan that also serves as a substrate during heating, and 8 is an outdoor water tray that collects dew condensed on an evaporator (not shown) on the indoor side 2 during cooling. Reference numeral 7 denotes a slinger ring for forcibly cooling the heat exchanger 9 by scattering water accumulated in the outdoor water tray 8. As shown in FIG. 2, reference numeral 12 designates several water guide plates that are integrally provided at the bottom of the outdoor water tray 8, and after the water is introduced from the water scooping part of the slinger ring 7, it gradually flows into the heat exchanger 9. It is formed in a curved shape that curves toward the direction.

The shape of this introduction plate 12 is such that it disperses the condensed water that has been rapidly stirred up by the slinger ring 7, prevents it from concentrating on one point on the heat exchanger 9, and distributes it as much as possible so that it is applied to the heat exchanger 9. There is.

Effects of the Invention As is clear from the above embodiments, the drain water treatment device for the air conditioner in this factory has a water guide plate integrally formed with the outdoor water tray, which reduces wind resistance compared to the conventional structure. In addition, by guiding the condensed water through several introduction plates, the water is branched when being led to the heat exchanger, and the speed at which it hits the heat exchanger is reduced. It has various advantages, such as being quiet because of the low heat exchanger, and increasing the area covered by condensed water in the heat exchanger by using several introduction plates, improving heat exchange efficiency.
