Abstract

PURPOSE:To enable sludge to be cleaned within a drain pan without taking out the drain pan by a method wherein a drain plug is arranged to cover the substantial entire surface of the deepest part of the drain pan just below a drain pump CONSTITUTION:A drain plug 11' is placed just below a drain pump 10 and occupies the substantial entire surface of the deepest part 9 of a drain pan 8. A sludge 12 produced through a continued operation of a ceiling buried type air conditioner is removed by removing the drain plug 11' and taking out the drain water, the drain plug 11' is returned to its original state and thus the sludge may easily be cleaned. Accordingly, an interior of the drain pan 8 can be cleaned without taking the entire drain pan 8 out of a cabinet 2. A periodic cleaning of the drain pan can be efficiently carried out; thus, a leakage of water from the air conditioner caused by a clogged state of a drain pump or incapability of operation may be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a ceiling-embedded humid air conditioner, particularly to a drainage structure of a drain pan.

BACKGROUND OF THE INVENTION In recent years, with the aim of saving space in air conditioners, ceiling-mounted humid air conditioners that utilize the inside of the ceiling have become increasingly diverse.

An example of the above-mentioned conventional ceiling-embedded humid air conditioner will be described below with reference to FIGS. 3 to 4.

In the figure, 1 is the main body of the ceiling-mounted humid air conditioner, and 2 is a cabinet that forms the outer shell of the main body 1 and is approximately rectangular parallelepiped. 3
is pasted on the inner surface of the cabinet 2 with a heat insulating material. Reference numeral 4 denotes an air suction port, and air is sucked in from the direction of arrow A, sent by a blower 5, cooled or heated by a heat exchanger 6, and blown out from an air blowing lower in the direction of arrow B for air conditioning.

8 is a drain pan located below the heat exchanger e, which guides drain water during cooling to the deepest part 9 of the drain pan 8, and is connected to the drain pump 1.
At 0, it is discharged from the main body 1. 11 is a drain plug, which is removed when it is desired to completely drain the drain water in the drain pan 8 in the direction of arrow C.

Problems to be Solved by the Invention However, with the above configuration, as the air conditioner continues to be turned on, sludge 12 consisting of dust and bacteria in the air accumulates in the deepest part 9 of the drain pan 8, and eventually drains. The suction port 13 of the pump 10 becomes cold and cannot drain water, causing water to leak from the air conditioner or becoming inoperable. Therefore, the drain pan 8 must be cleaned periodically,
At that time, remove the drain plug 11 and drain the drain water, then
The entire drain pan 8 has to be taken out of the cabinet 2, which is extremely complicated work, and when multiple types of air conditioners are installed in one room, etc.
There was a problem in that cleaning the drain pan 8 required a great deal of effort and time.

In view of the above problems, the present invention provides an air conditioner that can clean the sludge inside the drain pan without taking out the drain pan.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a drain plug that covers almost the entire surface of the deepest part of the drain pan directly below the drain pump.

Effects According to the present invention, when sludge accumulates in the deepest part of the drain pan, the inside of the drain pan can be easily cleaned by removing the drain plug and removing the sludge accumulated inside the drain plug.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to FIGS. 1 and 2.

Note that the same parts as those in the conventional example are given the same reference numerals and explanations are omitted.

A drain plug 11' is located directly below the drain pump 10 and occupies almost the entirety of the deepest part 9 of the drain pan 8.

In the ceiling-embedded air conditioner configured as described above, sludge 12 is generated due to continued operation of the air conditioner.
can be easily cleaned by removing the drain plug 11', draining the drain water, removing the sludge 12 accumulated inside the drain plug 11', and then returning the drain plug 11' to its original position. Therefore, the inside of the drain pan 8 can be cleaned without taking the entire drain pan 8 out of the cabinet 2 as in the conventional case.

Effects of the Invention As described above, the present invention provides a drain plug that covers almost the entire surface of the deepest part of the drain pan directly below the drain pump, so the inside of the drain pan can be easily cleaned without taking the entire drain pan out of the cabinet. can. Therefore, periodic cleaning of the drain pan can be carried out efficiently, and leakage of water from the air conditioner due to a stuck drain pump or malfunction of the air conditioner can be prevented.
