Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a window air conditioner in which an evaporator, a condenser, a compressor and the like are integrated.

[Conventional technology]

In this type of integrated window air conditioner, the air in the room is cooled by the evaporator and used as cold air, and the moisture in the air that passes through this evaporator is condensed to form drain water, which is guided to the outside of the room. It is discharged by a pump or sprinkled with water to the top of the condenser with a pump or the like, or equipped with a rotating plate on the drain receiver. The motors of the exhaust heat fans facing each other are placed at a high position where there is no influence of drain water.

[Problems to be solved by the device]

Among the above-mentioned conventional techniques, the present invention intends to effectively use the storage space by storing the exhaust heat fan motor facing the condenser in the lowest possible part of the frame. Do not let the drain water stay,
There is a problem that heat is not stored in the storage space.

[Means for Solving the Problems]

In order to solve the above problems, in the present invention, a drain receiving part and a partition wall for housing a motor are integrally formed on the lower base of the frame, and the motor is not affected by soren water, and the motor housing space is The effect of heat is minimized by letting the air flow through.

That is, evaporator 1, condenser 2, compressor 3
In a refrigeration cycle including the same, etc., and a window air conditioner in which the fan 4 is housed in the frame body 5, the outdoor side end portion 6a of the mounting frame 6 supporting the lower portion of the frame body 5 is extended outward and the mounting frame 6 A gap A communicating with the outdoor side is formed between the frame 5 and the frame 5,
On the other hand, a partition wall 7b for housing the motor 8 of the fan 4 is formed by extending upward from the lower base 7 of the frame body 5 in which the drain receiving portion 7a is formed, and the motor 8 is housed in the partition wall 7b. A lower surface of the lower base 7 and a bottom surface 7c of the lower base 7 in the partition wall 7b are opposed to each other with a gap B therebetween, and the lower base 7 is placed at an appropriate position on the bottom surface 7c.
Is provided with a through hole 9 communicating with the outside of the
This is a window air conditioner provided at a position in contact with the upper gap A.

Further, if the bottom surface 7c of the lower base 7 is provided with an inclined surface or an inclined groove 7d toward the through hole 9, it is convenient for discharging drain water that has entered the bottom surface 7c portion, and the through hole 9 and the mounting frame are almost the same. If the parallel horizontal shape is adopted, the opening area of the through hole 9 can be made large, and similarly, drainage can be favorably performed.

[Action]

When the window air conditioner is activated, the refrigerant acts to cool the air with the evaporator and the condenser to dissipate the heat of the refrigerant, and the refrigerant repeats the gasification and liquefaction refrigeration cycles, resulting in high indoor humidity. Then, the evaporator turns into moisture, which collects in the drain receiver at the bottom.

The drain water collected in the drain receiver is discharged to the outside, or is sprinkled on the condenser with a rotating plate or the like and evaporated and dissipated by the heat of the condenser.

On the other hand, the evaporator has a fan for cooling air and the condenser has a fan for discharging heat. The air in the room is cooled by the evaporator, the moisture is liquefied, and the cool air is returned to the room by the fan for cold air. The condenser sends the outdoor air to the condenser by means of an exhaust heat fan to remove the heat of the condenser and exhaust it.

Then, the drain of the drain receiving part is swelled by the wind, and when the drain water is sprinkled, some drain water may exceed the partition wall and enter the motor storage part.
The drain water flowing into the motor housing portion flows from the clearance B toward the through hole, and is discharged from the through hole through the clearance A on the mounting frame to the outside of the room.

On the other hand, since the gaps A and B are communicated with each other by the through holes, there is an air flow, and the heat from the motor does not stay in the motor housing portion, and has a function of promptly dissipating the generated heat.

Furthermore, since the bottom surface of the lower base in the partition wall is made into an inclined surface,
The drain water that has flowed into the partition wall quickly flows toward the through hole, and the through hole is horizontally elongated, so that the drain water quickly flows into the gap A, and the drain water stays inside the partition wall. Is not recognized.

Built-in fan etc. Reference numeral 6 denotes a mounting frame for mounting the window air conditioner on the window. The outdoor side end 6a of the mounting frame 6 extends outward, and a gap between the frame body 5 and the mounting frame 6 communicates with the outside. A
Is provided. Reference numeral 7 denotes a lower base of the frame body 5, and a drain receiving portion 7a and a partition wall 7b for accommodating the motor 8 of the heat exhaust fan 4 are integrally formed by resin molding or the like.

Reference numeral 7c denotes the bottom surface of the lower base 7 in the partition wall 7b for housing the motor 8, and a part of the motor 8 is placed on the upper end of the partition wall 7b.

And are opposed to each other via a gap B. Reference numeral 9 is a through hole that connects the bottom surface 7c to the outside of the lower base 7, and the bottom surface 7c is provided with an inclined surface or an inclined groove 7d toward the laterally elongated through hole 9. Reference numeral 10 is a window frame to which the mounting frame 6 is attached.

〔effect〕

The present invention has the above-described structure and operation. Since the lower base 7 is provided with the drain receiving portion 7a and the storage chamber for the motor 8 by the partition wall 7b, the drain water flowing down from the evaporator 1 is separated from the partition wall. It does not flow into the storage chamber of the motor 8 inside 7b, but is stored in the drain receiving portion 7a. Even if the drain water overflows the partition wall 7b and enters the storage chamber, a gap B is provided between the lower surface of the motor 8 and the bottom surface 7c of the lower base 7, so that the drain water may stay in the motor 8. Since there is no through hole 9 communicating with the outside of the lower base 7 at a proper place on the bottom surface 7c, the through hole 9 is drained to the outside of the lower base 7, and the through hole 9 is a gap on the mounting frame 6. Since it is in contact with A, the drain water drained is surely discharged to the outside of the room via the outdoor end 6a, so that there is no risk of the motor 8 being submerged by the drain water and causing a failure.

Further, since the through holes 9 communicate with each other through the gaps A and B to allow the outdoor air to ventilate to the motor 8 housing portion formed inside the partition wall 7b, heat is not trapped in the housing portion. The temperature rise can be suppressed.

In addition, the bottom surface 7c of the lower base 7 is provided with an inclined surface or an inclined groove 7d toward the through hole 9, so that there is an advantage that the bottom surface 7c is drained from the through hole 9 without water retention.

Further, if the through hole 9 has a horizontally long shape substantially parallel to the mounting frame 6 as shown in FIG. 3, the opening area of the through hole 9 is large and the drain water outflow surface is also large, so that drain water is drained. It can be done smoothly and there is no need to worry about clogging with dust.
