Description

  The present invention relates to an air conditioner drain pan, and more particularly to an air conditioner drain pan for cleaning muddy water generated from an air conditioner.

  Air conditioners such as office buildings and factories are generally installed behind the ceiling in order to effectively use indoor space and blow conditioned air from the ceiling to the entire room. This air conditioner includes a blower (fan), a heat exchanger (coil), a humidifier, an air filter, and a casing. When this air conditioner is operated, the condensed air becomes water droplets and drops from the heat exchanger during the heat exchange of the indoor air by the heat exchanger. Generally, an air conditioner is provided with a drain pan that accumulates drain water dripped from the heat exchanger. The drain water collected in the drain pan is discharged to the outside of the air conditioner by driving and draining a drain pump equipped in the drain pan.

  Further, when the air conditioner is operated, dust floating in the room, cigarette smoke, and the like adhere to the heat exchanger. These dust, cigarette smoke, etc. mix with the drain water dripped from the heat exchanger, fall into the drain pan, and accumulate in the drain pan as muddy water containing a lump of dust and the like.

  When the drain pump is driven and sucked from the drain pan in which the muddy water is accumulated, a lump of dust or the like contained in the muddy water closes the suction port and the discharge port of the drain pump, resulting in poor drainage.

  Conventionally, as a means for preventing this poor drainage due to muddy water, generally, regular cleaning has been performed. This cleaning has been carried out manually by disassembling the air conditioner until the drain pan and drain pump can be removed, and using a rag or waste cloth.

  On the other hand, for example, Non-Patent Document 1 discloses an air conditioner drain pan cleaning device. An air conditioner drain pan cleaning device disclosed in Non-Patent Document 1 is shown in FIG. A drain cleaning device 22 is connected to the electric vacuum cleaner 21 used for cleaning the air filter, and sludge water 26 and dry garbage 25 are sucked from the hose 23. The sludge water 26 sucked by the drain cleaning device 22 accumulates in the lower part of the drain cleaning device 22, and the dry garbage 25 is sucked by the electric vacuum cleaner 21 through the hose 24.
