Abstract

PURPOSE:To reduce noise by a constitution wherein water in a drain pan is sprinkled between an air guider and a heat exchanger by a slinger ring provided on a propeller fan for cooling the heat exchanger and then it is gathered by a water-driving plate and driven to the heat exchanger. CONSTITUTION:When a propeller fan 5 rotates, a slinger ring 8 scrapes up the water gathered in a drain pan 7. The water thus raised up is all driven to a heat exchanger 10 along a water-driving plate 9 provided between an air guider 6 and the heat exchanger 10. Accordingly, the water is made free from being sprinkled from a suction louver as is the case in a conventional device, and thereby the generation of noise can be prevented, while the efficiency of the heat exchanger can be increased.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a drain water treatment device for collecting drain water in a drain pan in an air conditioner.

In general, this type of drain water treatment equipment is, for example,
゛The drain water collected in the drain pan inside the Indian-type room cooler is stirred up by a slinger ring attached to the outer circumference of the cooling propeller fan of the condenser to form large water droplets, and these are sprayed into the condenser by the propeller fan. It's evaporated.

However, in the case of such a structure, in the case of condensed water in the form of water droplets, A immediately after being scraped off by a slinger ring as shown in
The water droplets in this area hit the propeller fan, condenser, and surrounding structures and are reflected diffusely, flying to the air intake port of the cooling propeller fan and causing damage to the walls and the condenser below.
) - Drop into the container.

Therefore, there were problems such as walls rotting and water splashing on passersby. Another disadvantage was that the condensed water stirred up by the slinger ring caused a lot of noise when it hit the surrounding walls.

The present invention eliminates the above-mentioned conventional drawbacks, and one of its objects is to reduce noise when condensed water is splashed by slinger ring.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in three parts with reference to 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. The outdoor side 3 is provided with a heat exchanger 10 serving as a condenser, a propeller fan 5 driven by an electric motor 4, an air guide 6, and a compressor 11, respectively. γ is a drain pan that also serves as a substrate, and collects dew condensed on an evaporator (not shown) on the indoor side 2.

Reference numeral 8 denotes a slinger ring attached to the propeller fan 6, which scatters water accumulated in the drain pan 7 to forcibly cool the heat exchanger 1o. Reference numeral 9 denotes a drain water introduction plate located between the air guider 6 and the heat exchanger 100, which collects water scattered by the slinger ring 8 and guides it to the heat exchanger. This drain water introduction plate 9 is attached to the air guider 6, drain pan 7, etc. by means such as welding near the part A where drain water is intensively scattered from the water surface, as shown in FIG. . Moreover, this drain water introduction plate 9 is formed in a curved shape that gradually curves inward as it goes from the air guider 6 toward the heat exchanger 10, and is shaped to guide the scattered water toward the heat exchanger without reflecting it as much as possible. It becomes.

Reference numeral 12 denotes a prevention wall extending over the upper part of the drain water introducing plate 9, which prevents the flow of the circumferential component of the splashing water and promotes the water collecting action of the drain water introducing plate 9. The promoting effect can be further increased by installing the prevention walls 12 at regular intervals on the drain water introduction plate.

In the above configuration, when a certain amount of condensed water accumulates in the drain pan 7 due to the rotation of the propeller fan 6, the slinger ring 8 starts scooping up the water. The distribution of the water raised at that time is as shown in Figure 3. The water flows to the heat exchanger 10 due to the flow of the wind, but in the A part, the amount, water pressure, and pressure are both large, so there is a risk of splashing outside the machine and noise generation as described above. However, the curved shape of the drain water introduction plate 9 Page 5:
By reducing the incident angle and reflection angle, the scattered water flows smoothly into the heat exchanger 10, and the water that collides with the prevention wall 12 at the top of the drain water introduction plate 9 and falls is
The impact of the splashed water against the drain water introduction plate 9 is alleviated, thereby reducing noise.

As is clear from the above embodiments, the drain water treatment device for an air conditioner according to the present invention includes a drain pan for storing condensed water, a heat exchanger, and a propeller fan for cooling the heat exchanger. An air guider is provided respectively, and a slinger ring is provided on the propeller fan to scatter water accumulated in the drain pan, and between the air guider and the heat exchanger, the water scattered by the slinger ring is collected and guided to the heat exchanger. This is equipped with an introduction plate, and by guiding the part where condensed water is concentratedly scattered from the horizontal surface and the lower end of the slinger ring to the heat exchanger,
This prevents condensed water from being diffusely reflected by a propeller fan, splashing out from the suction louver, and dripping onto the wall or concrete below. The efficiency amplifier of the heat exchanger and the sound generated after the slinger ring stirs up the condensed water can be reduced by guiding and leading. In addition, by forming the introduction plate into a curved shape that curves inward as it goes from the air guider to the heat exchanger,
This has various effects, such as smoother flow of condensed water to the heat exchanger and improved heat exchange efficiency.
