Description

[Detailed Description of the Invention] This invention relates to a drain overflow prevention mechanism for an air conditioner, particularly a ceiling-embedded air conditioner that is suspended above the ceiling.

Traditionally, ceiling-mounted air conditioners have been difficult to maintain levelness compared to floor-standing types due to the nature of the construction work.
Due to poor maintenance, the drains were easily clogged with dirt, often resulting in drain overflow accidents.

Moreover, once an accident occurs, the ceiling and floor surfaces are contaminated, and in most cases the damage is greater than with floor-standing types.

The purpose of this invention is to provide an air conditioner that can prevent such drain overflow accidents by using a temperature controller that air conditioners normally have.

Fig. 1 is a perspective view showing an embodiment of this invention before the main body of the air conditioner is installed. 2 sets of fixed bangers are suspended by 3, 2 sets of movable bangers are placed perpendicularly on the fixed bangers and can be moved forward, backward, left and right by specific dimensions, and 4 is the movable banger. There are four sets of hooks suspended from the banger by four sets of bolts 5, nuts 6, and anti-vibration rubber 7.

On the other hand, 8 is the air conditioner main body, which has a frame 9 with four sets of U-shaped notches 9a at its lower part, and by hooking the lower end of the hook 4 thereon, it can be hung in the ceiling. ing.

When hanging, horizontal adjustments are made by sliding the movable banger 3, and vertical adjustments are made by adjusting the nuts 6. The position of the air conditioner main body 8 can be adjusted correctly.

10 is the inlet of the air conditioner, 11 is the outlet, and inlet 1
0 has a cooler 12 and a drain pan 13, and a temperature sensing part 15 of a temperature regulator having a main body in an electrical component box 14 is fixed to this drain pan through a capillary tube 16.

FIG. 2 is an enlarged sectional view of the vicinity of the suction port of a conventional air conditioner.
8 to the lower end of the panel 17.

On the other hand, FIG. 3 is an enlarged sectional view of the vicinity of the suction port of the air conditioner of this invention, and in the figure, the temperature sensing part 15 of the temperature controller is fixed to the upper end of the drain pan 13 by a mounting bracket 18. .

Next, talking about the operation, the temperature sensing part 15 of the temperature controller senses the temperature of the intake air and controls the operation of the air conditioner in the same way in both the case of Fig. 2 and the case of Fig. 3. .

However, if the water level in the drain pan 13 were to rise for some reason, a drain leakage accident would occur in the conventional example shown in Fig. 2, but according to the embodiment of this invention shown in Fig. 3, the water level would rise to a certain extent. The hot section 15 is submerged in the cooling water drain.

In this case, the temperature of the drain is close to the cooler surface temperature and lower than the intake air temperature, so the temperature regulator is activated to stop the cooling operation of the air conditioner.

Therefore, the water level in the drain stops rising at that point, and a drain leakage accident does not occur.

In the above embodiment, the temperature sensing section 15 is mounted at the upper end of the drain pan, but it may be mounted at any other location within the drain pan as long as it is submerged in water when the drain water level rises.

Furthermore, this invention can be applied to air conditioners other than those installed in the ceiling.

As described above, according to this invention, serious accidents such as drain leakage can be prevented by simply changing the position of the temperature sensing part of the conventional temperature regulator and without adding any special parts. effective.
