Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dew receiving device for an air conditioner in which an induction air outlet is provided near the air outlet so that dew does not easily form around the air outlet.

[0002]

2. Description of the Related Art It is known that dew adheres around a blowout port from which cold air is discharged.

Therefore, in Japanese Utility Model Publication No. 52-56671, an induction blow-out port is provided near this blow-out port and
It is shown that a drain receiver is formed below the induction outlet.

With such a structure, the uncooled air is guided from the induction outlet by the cool air discharged from the outlet. Therefore, uncooled air flows around the air outlet to suppress dew formation around the air outlet as much as possible. Further, drain water adhering to the inner wall of the air outlet or the like is collected in the drain receiver via the induction air outlet and is naturally evaporated by the drain receiver.

[0005]

Although the drain water collected by the drain receiver is allowed to spontaneously evaporate by the drain receiver, the collected drain water causes
It is conceivable that dew may form on the outer wall of the drain receiver.

An object of the present invention is to prevent dew on the outer wall of the drain receiver from being easily caused by the drain water collected through the induction outlet and to prevent dew from dripping into the room. .

[0007]

In order to achieve this object, the present invention forms an air layer below the drain receiver under the drain receiver that receives the drain water that has flowed in through the induction outlet. A bottom plate is provided for this purpose.

[0008]

The drain water collected in the drain receiver through the induction outlet is spontaneously evaporated, but the air layer formed below the drain receiver prevents dew on the outer wall of the drain receiver.

Reference numeral 17 is a heat exchanger, 18 is a drain pan, 19 is a cross-flow fan, 20 is an outlet frame, and the outlet 14 thereof is provided with horizontal blades 21 and vertical blades 22.

The room air sucked from the suction panel 11 by the rotation of the cross flow fan 19 is cooled or heated by the heat exchanger 17 and then blown out from the discharge port 14 (solid arrow in FIG. 2 and FIG. 1). reference).

FIG. 3 is a cross-sectional view of the main part of the lower portion of the air outlet 14.
Reference numeral 23 is a support hole into which the shaft of the vertical blade (see FIG. 2) 22 is inserted, and 24 is an induction blowout port formed below the blowout port 14, which is located in a slit shape over substantially the entire width of the blowout port 14. ing. Reference numeral 25 is a drain receiver, and a bank 26 is attached to the rear edge thereof. The bank 26 is made of expanded polyethylene. Reference numeral 27 denotes a bottom plate provided under the drain receiver, and by this bottom plate 27, an air layer 28 is provided below the drain receiver 25.
Are formed.

With such a structure, the cold air cooled by the heat exchanger (see FIG. 2) 17 flows along the inner wall 29 of the blowout port 14 as shown by the solid line arrow in FIG. Due to the air flow indicated by the solid arrow, the air in the space 30 between the drain receiver 25 and the blow-out port 14 is blown out from the induction blow-out port 24.
It is led from the lower part of 4 to the front as shown by the one-dot chain line arrow.

Further, the primary air flows along the bottom plate 27 as shown by the two-dot chain line arrow. In this way, the air guided from the induction outlet 24 surrounds the cool air discharged from the outlet 14 to prevent dew condensation near the front portion 31 of the bottom plate 27 of the outlet 14. Here, even if the drain water 32 adheres to the inner wall 29 of the air outlet 14, the drain water 32 flows down the inner wall 29 and is guided to the drain receiver 25 via the induction air outlet 24. Since the bank 26 is attached to the drain receiver 25, the drain water 33 guided to the drain receiver is dammed here and is naturally evaporated.
Further, since such drain water 33 is relatively small, there is no possibility that the dammed drain water 33 overflows the bank 26.

However, the drain water 33 is blocked.
Due to this, the lower part 34 of the drain receiver 25 is cooled, whereas the uncooled primary air is flowing along the bottom plate 27 as shown by the chain double-dashed line. Due to this, dew condensation tends to occur on the drain receiver 25, but since an air layer 28 is formed below the drain receiver 25 by the bottom plate 27, this air layer 28 serves as a heat insulating function and serves as a drain receiver 25. No dew is formed at the bottom of the.

Reference numeral 42 denotes a printed circuit board on which the operation lamp 40 and the operation button 15 are arranged, to which the lead wire 43 is connected. FIG. 5 is an exploded view of the operation lamp 40, the operation button 15, the printed circuit board 42, etc. The first insertion hole 44 into which the operation lamp 40 is inserted and the operation button 15 are inserted in the front portion of the blowing frame 20. The second insertion hole 45 and the boss 47 for fixing the screw 46 are formed. Reference numeral 48 is a display plate attached to the front surface of the blowing frame 20. Reference numeral 49 is a heat insulating material attached to the inner side wall 50 of the blowing frame 20. That is, the side wall 51 of the blow-out frame 20 serves as the wall of the blow-out port 14, and dew easily occurs on the inner side wall 50. Therefore, a heat insulating material 49 is attached to prevent this. The printed circuit board 42 is provided with the operation lamp 40 and the switch 52 to which the operation button 15 is attached, and the lead wire 43 is connected to the printed circuit board 42. 53 is an insulating sheet attached to the back side of the printed circuit board 42,

2 is attached to the blowing frame 20, an insulating sheet 53 is applied to the back side of the printed circuit board 42, and the printed board 42 is fixed with a screw 46. At this time, since the insulating sheet 53 is longer than the printed board 42, the left end 56 of the insulating sheet 53 is inserted between the printed board 42 and the heat insulating material 49. By such insertion work, the insulating sheet 53 is attached to the printed board 42 in a wavy state. Therefore, there is no possibility that the insulating sheet 53 will be rolled up, and the solder 54 and the legs 55 of the terminals on the back side of the printed circuit board 42 are surely covered and protected by the insulating sheet 53. As a result, insulation failure due to dew is less likely to occur.
