Drain water bacteriostatic structure for air conditioner
A drain water bacteriostatic structure for an air conditioner is provided with a drain pan 8 for holding drain water generated in an air conditioner 1 and an upright antibacterial member 50 which is provided in the drain pan 8 . The antibacterial member 50 is provided with an antibacterial agent 50 B. The length L 3 of the antibacterial member 50 in the up-down direction is set such that the lower end portion 50 a of the antibacterial member 50 is immersed in drain water when the drain water is at the minimum water level L 1 in the drain pan 8 , and the upper end portion 50 b of the antibacterial member 50 is exposed above the maximum water level L 2 of drain water in the drain pan 8 by a predetermined length H or more.
1. A drain water bacteriostatic structure for an air conditioner, comprising:
a drain pan for holding drain water generated in an air conditioner; and
an upright antibacterial member which is provided in the drain pan,
wherein said antibacterial member has an antibacterial agent and the length L 3 of said antibacterial member in the up-down direction is set such that a lower end portion of the antibacterial member is immersed in drain water when drain water is at the minimum water level L 1 in the drain pan, and an upper end portion of the antibacterial member is exposed above the maximum water level L 2 of drain water in the drain pan by a predetermined length H or more, wherein
the antibacterial member is held in such a manner that it can slide down from above,
said antibacterial member is formed of a mixture of a holding material having water solubility and an antibacterial agent having water solubility in granular form or pellet form, and
when the antibacterial agent, which is submerged in drain water in a lower end portion of the antibacterial member, is eluted in the drain water and reduced, the antibacterial agent, which is located above the actual water level of the drain water and not eluted, moves down from above in response so as to be supplied in sequence.
2. The drain water bacteriostatic structure for an air conditioner according to claim 1 , further comprising a drain pump, wherein the antibacterial member is provided in a portion where the drain pump is installed.
3. The drain water bacteriostatic structure for an air conditioner according to claim 1 , wherein the antibacterial member is formed to be in columnar form.
4. The drain water bacteriostatic structure for an air conditioner according to claim 3 , wherein the columnar form is formed by uniformly kneading the mixture of the holding material and the antibacterial agent into a synthetic resin material.
