Abstract

PROBLEM TO BE SOLVED: To shorten the washing time of a water receiver and a drain-device by a method wherein a removable lid is attached to the water receiver at the mounting part of the drain-up device to wash the drain-up device or the circumference of suction port of the same device. SOLUTION: A removable lid 11, provided with a rubber plug 12 for draining, is attached to a service port, having a size capable of washing a drain-up device 9, provided on a water reserving unit 10 at the lower surface of the mounting part of the drain-up device of a water receiver 8, or the circumference of a suction port 17, by screwing through a packing. When drain in the drain-up device 9 can not be drained, the rubber plug 12 is pulled out to extract drain water, then, the lid 11 is removed once to wash the drain-up device 9 or the circumference of the suction port 17 and, thereafter, the lid 11 is attached again whereby the drain in the drain-up device can be drained. According to this method, the washing of the drain-up device 9 or the circumference of the suction port 17 can be effected without removing the water receiver 8.

Detailed Description of the Invention

[0001]

[0001] The present invention relates to an air conditioner.

[0002]

2. Description of the Related Art In an air conditioner incorporating a conventional drain-up device, for example, a ceiling-embedded air conditioner, dust or amoeba-like slimy water accumulates in a water receiver after several years have passed since the air conditioner was used. Moreover, these are accumulated around the suction port of the drain-up device, and the drain-up device cannot drain water.
In this case, in order to recover, after temporarily removing the decorative panel 4 ', the suction grill 5'and the water receiver 8'attached to the lower surface of the unit as shown in FIG. 5, the water receiver 8'and the drain-up device 9 are removed. 'Has to be cleaned, which is a very time consuming task. Further, a rubber stopper 12 'for removing drain water accumulated at the time of removing the water receiver is provided on the lower surface of the water receiver, but the inside of the water receiver cannot be washed from the hole of this stopper.

Regarding the air conditioner having a built-in drain up device, Japanese Patent Laid-Open Nos. 6-137586, 5-71749 and 5-141
There are 686 and 4-371732 publications, but neither of them considers the above.

[Problems to be Solved by the Invention] After several years have passed since the use of the air conditioner, dust and amoeba-like lukewarm accumulated in the water receiver, and further, these accumulated around the suction port of the drain-up device, and the drain-up device was It cannot be drained. In this case, for cleaning, it is necessary to temporarily remove the water receiver attached to the lower surface of the unit, and then to wash the water receiver and the drain-up device, which is a very time-consuming operation. An object of the present invention is to shorten this cleaning time.

[0005]

In order to achieve the above object, the present invention provides a water receiver of a drain-up device mounting portion with a removable lid for cleaning the drain-up device or a suction port of the drain-up device. By installing this, if the drain up device cannot drain water, you can remove the lid once, wash it, and then attach the lid again.
The cleaning time can be shortened.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described with reference to FIGS. FIG. 4 is a sectional view of a conventional ceiling-embedded cassette type air conditioner having a built-in drain-up device 9 '. A fan 3'is attached to the center of a box-shaped cabinet 1 ', and a heat exchanger 2'is arranged around it. At the lower part of the heat exchanger 2 ', a water receiver 8'for receiving drain water dripping from the heat exchanger 2'is attached, and the dropped drain water is guided to a passage provided in the water receiver 8'. Are collected in the water storage section 10 '. A drain-up device 9'is installed above the water storage unit 10 ', and the blades 15 of the drain-up device are rotated by the electric motor 14 to discharge the drain water out of the device. Furthermore, the water receiver 8 '
A decorative panel 4'in which an air intake 7'and an air outlet 6'are arranged is attached to the lower surface of the.

Here, depending on the place where the air conditioner is installed, dust or the like in the air is mixed with the drain water in the water receiver 8'to form a sludge, which is in the vicinity of the suction port 17 of the drain up device or in the drain up device. Since the deposits are deposited around the blades 15, the rotation of the blades and the function of the suction port 17 or the discharge port 16 of the drain-up device are hindered, the drainage becomes impossible, and the overflow preventive device of the water receiver 8 ′ operates to operate the air conditioner. It will stop. In order to restore this, it is necessary to clean the inside of the drain-up device 9'or the water receiver 8 ', and in order to carry out the cleaning, as shown in FIG. 5, the decorative panel once attached to the lower surface of the air conditioner. 4 ',
It is necessary to remove the suction grill 5'and the water pan 8 ',
It was a very laborious task.

FIG. 1 is a sectional view of the ceiling-embedded cassette type air conditioner of this embodiment. 2 shows an enlarged view of the drain-up device mounting portion. The water reservoir 10 on the lower surface of the drain-up device mounting portion of the water receiver 8 is provided with a service port of a size capable of cleaning the drain-up device 9 or the vicinity of the suction port 17 of the drain-up device. A removable lid 11 is attached by screwing through a packing. Further, the lid is provided with a rubber stopper 12 for draining water. Here, as described above, when the drain-up device 9 cannot drain water, the rubber plug 12 is pulled out to drain the drain water, and then the mounting screw of the lid 11 is removed to temporarily remove the lid 11, and the drain-up device 9 or the drain-up device is removed. After cleaning the area around the suction port 17 of the device, by attaching the lid again, the drain-up device 9 can be drained and the air conditioner can be restored. By providing the lid 11, the drain up device 9 or the vicinity of the suction port 17 of the drain up device can be cleaned without removing the water receiver 8 attached to the lower surface of the air conditioner, which has the effect of shortening the working time. Furthermore, by setting the size of the lid 11 so as to fit inside the suction port of the decorative panel 4, the suction grill 5 and the lid 11 can be removed without removing the decorative panel 4 and the water receiver 5 as shown in FIG. As a result, the drain-up device 9 or the area around the suction port 17 of the drain-up device can be cleaned, and the working time can be greatly reduced.

[0009]

According to the present invention, by providing the lid on the water receiver of the air conditioner, the drain up device or the vicinity of the suction port of the drain up device without removing the decorative panel and the water receiver attached to the lower surface of the air conditioner. The cleaning can be performed and the work time is shortened.
