Description

  The present invention relates to an air conditioner that is provided with an antibacterial / antifungal resin molded body and can suppress generation of slime in drain water over a long period of time, and does not cause failure due to slime.

  The structure of a conventional air conditioner will be described (see Patent Document 1).

  FIG. 9 shows a conventional air conditioner described in Patent Document 1, and includes a heat exchanger 1, a fan 2 that sends out the air heat-exchanged by the heat exchanger 1 into the room, and the heat exchanger. It is comprised from the water tray 3 which receives the drain water condensed by this, and the antibacterial and antifungal resin molded body plate 4f.

  If drain water stored in the water tray 3 is left for a long period of time, microorganisms may propagate and sticky substances (slime) may be generated. The slime generated in the drain water causes the failure of the air conditioner such as the drain pump and the drain hose being blocked and the drain water leaking in due course.

As a method for solving such a problem, there is an idea of dispersing an antibacterial and antifungal agent in a drain pan so that microorganisms do not propagate in the drain water.
However, when the drain pan is composed of a resin molded body, if a large amount of the antibacterial / antifungal agent is dispersed in the drain pan, the molding of the antibacterial / antifungal agent and the resin base material is reduced. As a result, the drain pan cannot be manufactured with high molding accuracy, and as a result, the dispersion of the antibacterial / antifungal agent in the drain pan is limited. The evaluation was inferior in terms. Moreover, when the resin component is large, there is a problem that the cost becomes high.

Therefore, in Patent Document 1, the antibacterial / antifungal plate 4f containing a filler that facilitates elution of the antibacterial / antifungal agent into the drain water is disposed in the drain pan, and slime is generated in the drain water. A method of suppressing this has been proposed. However, in the conventional plate shape, the shape is simple, but it is difficult to fit the special shape of the water tray such as a step or an inclination provided for collecting drain water, and the place of placement is difficult to be stable, a drainage groove, etc. There was also a problem that the drain water drainage was obstructed.

It is provided as follows. Since the drain water collected in the water tray 3 is always discharged by the drain pump 6 to the outside of the air conditioner, the antibacterial / antifungal resin molded body 4c is disposed in the water tray 3 near the suction port of the drain pump 6. Thus, if drain water is accumulated, the antibacterial / antifungal resin molded body 4c is almost always immersed in the drain water, which is effective in preventing slime generation.

Moreover, since the size around the suction port of the drain pump 6 is sufficient, the size of the antibacterial / antifungal resin molded body 4c may be about several tens to several tens of cm in diameter. Further, since the accumulated drain water is forcibly drained by the drain pump 6, the drain water flows toward the suction port of the drain pump 6, and therefore the antibacterial / antifungal resin molded body 4c is always attracted to the periphery thereof. There is no need to think about fixing.
In this way, it is possible to stably suppress the generation of slime in the drain water in the antibacterial / antifungal resin molded body 4c with an inexpensive configuration having a small and simple shape, and the occurrence of the failure due to the slime. It is possible to provide an air conditioner that has no air conditioner.

(Embodiment 4)
FIG. 4 shows a component diagram of an air conditioner according to the fourth embodiment of the present invention.
