Definitions
- the present invention relates to a structure of a drain water bacteriostatic part of an air conditioner.
- a drain pan that receives drain water and discharges it to the outside is provided at the bottom of the heat exchanger of the air conditioner.
- the drain water once stored in the drain pan is discharged to the outside through an inclined groove force drain pipe provided in the drain pan and loaded into the ceiling.
- a drain pump including a drain up kit
- the drain water stays in the drain pan for a predetermined time.
- bacteria propagate in the drain water in the drain pan, causing problems such as a strange odor due to slime formation and clogging of the drain piping.
- an antibacterial agent-containing resin composition layer and a resin sheet or film are sequentially laminated on the inner wall surface of a drain pan (see Patent Document 1).
- the antibacterial agent-containing resin composition layer contains crystalline polypropylene, an inorganic filler, and an antibacterial agent. This technique suppresses bacteria from propagating in the drain water by the antibacterial agent that has permeated through the resin sheet or film acting on the drain water.
- Patent Document 2 there has been proposed a technique for bonding a copper alloy foil having a bactericidal action on the bottom surface of a drain pan (see Patent Document 2). Furthermore, a technique has been proposed in which a disinfectant is mixed in the material forming the drain pan, and the drain water is irradiated with ultraviolet rays by an ultraviolet lamp (see Patent Document 3).

- Antibacterial agent 50B dissolves in water and exerts a bactericidal effect.
- Specific examples of the antibacterial agent 50B include water-soluble glass carrying an inorganic antibacterial agent.
- the antibacterial member 50 is replaced with a new antibacterial member 50 when the antibacterial agent 50B in the container 50A disappears after a certain period of use.
- the antibacterial agent 50B has a minimum concentration necessary to exert a bacteriostatic effect.
- This minimum concentration depends on the type of antibacterial agent 50B used. Therefore, the initial amount (dipping amount) of the antibacterial agent is ensured at this minimum concentration under the worst conditions (conditions where the antibacterial agent elution concentration is the lowest) within the range of normal use conditions, and is used for the years of use. It is determined so that an effective and bacteriostatic effect can be exerted throughout.
- Fig. 24 shows the relationship between the age (hours) of use of antibacterial agent 50B and the concentration of antibacterial agent 50B in the drain water.
- Antibacterial agent 50B is consumed over the years of use, and the concentration of antibacterial agent 50B decreases (see A to B in Fig. 24). Therefore, in order to exert the bacteriostatic effect for N years, the initial amount of antibacterial agent is the sum of the amount of antibacterial agent that can secure the necessary minimum concentration after N years and the amount of antibacterial agent consumed in N years. Therefore, many antibacterial agents are required.
