Abstract

PURPOSE:To prevent drain water from being slimed, by providing a net made of resin containing metallic fibers at the downstream part of a drain pan. CONSTITUTION:A net 4 made of resin containing metallic fibers is arranged at the downstream part of a drain pan 3. When drain water, condensed in an evaporator 1 and containing nutritive substances or the like, flows down into the drain pan 3, the drain water contacts the net 4 and oxidizes the metallic fibers having a large surface area, whereby ions of copper, silver or the like are eluated. The copper ion or the silver ion in the drain water prevents the generation of agar-like slime of iron bacteria or the like, whose nutritive source is the nutritive substances dissolved in the drain water, by the mildew resistant and alga resistant effects of the copper or silver ion in the drain water. According to this method, clogging with slimed drain water may be prevented and the generating rate of water leakage, bad smell or the like may be reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a drain water treatment device for an air conditioner.

Conventional technology In a conventional device, as shown in Fig. 4, the air conditioner drain pan 10
A cloth bag 103 containing an anti-slime agent was set in the container 1, and the agent came into contact with the drain water from the evaporator 102, and its medicinal effect was used to prevent slime formation in narrow areas where the flow was stagnant.

Problems to be Solved by the Invention In such a configuration, the agent 10 having a slime-preventing effect
It is difficult to control the sustained release of drugs such as penzetonicum chloride (No. 3), and considering that they are maintenance-free for a certain period of time, a considerable amount of the drug is required, and small air conditioners for home use have had problems with space to store the drugs. .

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a simple device that can prevent drain water from turning into slime for a long period of time with a small amount of slime-preventing agent using sustained release of metal ions such as copper and silver and antibacterial action.

Means for Solving the Problems In order to solve the above problems, the present invention provides a resin net containing metal fibers at the downstream portion of the drain pan.

Effect The above structure increases the surface area by making the anti-bacterial properties of copper and silver ions and the corrosion-resistant metal into ultra-fine wires, ensuring the concentration of eluted metal ions, and eliminating the cause of lime formation in air conditioner drain water. It is possible to prevent the propagation of iron bacteria, etc., and eliminate damage caused by water leakage caused by clogging of drain water with slime.Embodiment An embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a configuration diagram of an air conditioner showing the state of the device, FIG. 2 is a perspective view of the main parts, and FIG. 3 is a front view of a mesh made of resin containing metal fibers.

When indoor air passes through an evaporator 1 using a blower fan 2, moisture in the air is condensed in the evaporator 1, and drain water is collected in a drain pan 3 and discharged outside via a drain hose (not shown). A resin net 4 containing metal fibers is placed downstream of the drain pan 3.

When the drain water containing nutrients condensed in the evaporator 1 flows down to the drain pan 3 according to the above-described structure, it comes into contact with the screen 4, oxidizes metals having a large surface area, and elutes ions such as copper and silver. The copper and silver ions in the drain water containing these ions prevent the generation of agar-like slime, such as iron bacteria, which use the nutrients dissolved in the drain water as their nutritional source due to their anti-algae action.

The table below shows examples of preventing slime formation of metal fibers and their effects.

Table 1. Effects of the Invention As is clear from the above examples, the present invention can prevent the generation of slime such as iron bacteria that uses nutrients contained in drain water as a nutrient source, and can prevent slimes from forming in narrow areas and stagnation in the drain water flow path. It is possible to prevent water clogging due to slum formation in areas where water leaks occur, and to reduce the incidence of water leaks, strange odors, etc.
