On the other hand, a sound shielding plate 9 is provided between the compressor 2 and the lower surface plate 5 while the lower surface plate 5 is provided with an opening 5 having a diameter smaller than the same of the sound shielding plate 9 whereby noise, generated from the compressor 2, can be prevented by the sound shielding plate 9 while a ventilating force for cooling the outer periphery of the compressor 2 is provided by the suction of the air discharging fan 12 whereby cooling effect is increased.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention improves the sound insulation and heat insulating properties of a window air conditioner in which a refrigeration cycle such as a compressor, a condenser and an evaporator is integrated, and the cooling effect of the compressor.

[0002]

2. Description of the Related Art In a window air conditioner having a refrigeration cycle mechanism inside a frame, operating noises of a compressor, a blower fan and an exhaust fan tend to be emitted as noise into the room.
It is known that each member is provided with a vibration damping mat, a sound absorbing material and the like.

[0003]

In particular, since the temperature of the main body of the compressor gradually rises during use, it is necessary to effectively dissipate heat to enhance the air-cooling effect. On the other hand, in order to absorb the operating noise. There is a contradictory problem that the air-cooling effect is hindered when surrounded by sound absorbing felt.

[0004]

In order to solve the above-mentioned problems, the present invention provides a frame 1 with a compressor 2, a condenser 3,
In a window air conditioner having a built-in refrigeration cycle including an evaporator 4 and the like, the compressor 2 is replaced by a lower plate 5 and an upper plate 6.
A refrigerant discharge pipe 8 which is surrounded by a partition plate 7 provided on the side and which connects the compressor 2 and the condenser 3 to each other.
Is inserted through a large opening 7a provided in the partition plate 7 communicating with the suction side of the exhaust fan 12, and the compressor 2 and the bottom plate 5
And a sound insulating plate 9 is provided between the sound insulating plate 9 and the sound insulating plate 9.
Is provided and the sound absorbing felt 11 is wound around the outer periphery of the compressor 2 with a ventilation gap 10 interposed therebetween to improve the ventilation of the outer periphery of the compressor 2 and to improve the sound insulation effect.

Further, the sound absorbing felt 11 has a wavy shape, and the air gaps 10 are formed by the peaks and valleys of the waves so that the cooling air of the compressor 2 can pass therethrough.
The sound absorbing felt 11 is brought into contact with the compressor 2 at the wave troughs to hold the sound absorbing felt 11, and to have the effect of enhancing the sound insulation effect.

[0006]

When the air conditioner is operated, the refrigerant liquefied by the compressor 2 cools the air while being gasified by the evaporator 4, while the condenser 3 dissipates the heat of the refrigerant to reliquefy it, thereby repeating the refrigeration cycle. The heat radiation from the exhaust fan 1 provided facing the condenser 3
2 is released to the outside of the room.

On the other hand, the heat of the compressor 2 is sucked by the exhaust fan 12 through the large opening 7a through which the partition plate 7 is inserted, and the air (cold air) passing through the opening 5a provided in the lower plate 5 is 2 rises in the ventilation gap 10 between the sound absorbing felt 11 and the sound absorbing felt 11, and is discharged to the outside through the large opening 7a.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of the air conditioner for windows will be described below with reference to the drawings showing the embodiments.
・ The condenser 3, the evaporator 4, etc. are housed, the refrigerant is circulated by the compressor 2, the indoor air is cooled by the evaporator 4, the humidity in the indoor air becomes a dew drop, which flows downwards and accumulates in the drain pan 13, and is discharged to the outside of the room. Or scoop it up on the condenser 3 to evaporate it.

Reference numeral 5 denotes a lower surface plate which constitutes the lower portion of the frame 1, and has an opening 5a for ventilation. 6 is a top plate provided on the upper part of the compressor 2, 7 is a partition plate that surrounds the side of the compressor 2, and is formed of metal, resin, etc. Form.

A discharge pipe 8 connects the compressor 2 and the condenser 2 to circulate a refrigerant, and the discharge pipe 8
Is provided on the partition plate 7 and is provided on the intake side of the exhaust fan 12 and the large opening 7
It penetrates through a and protrudes to the side of the capacitor 3 for communication,
It is desirable that the large opening 7a has a diameter sufficiently larger than the outer shape of the discharge pipe 8.

Reference numeral 9 denotes a sound insulating plate provided between the compressor 2 and the lower surface plate 5 for insulating noise emitted from the compressor 2. The sound insulation plate 9 has a diameter smaller than the inner diameter of a noise felt 11 described later, and is attached so as to face an opening 5a provided in a lower surface plate 5 having a diameter smaller than the sound insulation plate 9. The draft is bypassed to the outer periphery of the plate 9 and rises, and the draft force generated in the ventilation gap 10 on the outer peripheral side of the compressor 2 sucks air into the ventilation gap 10 to cool the compressor 2.

Reference numeral 10 denotes a ventilation gap provided on the outer periphery of the compressor 2, and 11 denotes a sound absorbing felt wound around the outer periphery of the compressor 2 through the ventilation gap 10. The sound absorbing felt 11
If, for example, the shape of is corrugated, the valley of the corrugation is in contact with the outer periphery of the compressor 2, and the ventilation gap 10 can be formed in the peak portion.

Reference numeral 12 denotes an exhaust fan provided so as to face the condenser 2. The exhaust fan 12 has a function of removing heat of the condenser 2 and discharging the heat to the outside of the room. Therefore, the hot air around the compressor 2 is sucked to the condenser side through the large opening 7a of the partition plate 7, merges with the wind of the exhaust fan 12, and is exhausted.

Reference numeral 13 denotes a drain pan for allowing dew drops (drain water) generated by the evaporator 4 to flow down and to be collected. Generally, the drain pan is guided to and stored below the condenser 3 and the drain water is discharged directly to the outside of the room by a hose. A means for scraping up the drain water toward 3 and evaporating it with the heat of the condenser 3 is used.

[0015]

The present invention has the above-mentioned structure and operation, and the heat generated from the compressor 2 is insulated and sound-insulated by the sound absorbing felt 11, the partition plate 7, the lower surface plate 5 and the upper surface plate 6. There is.

Further, the air entering through the opening 5a of the lower plate 5 does not go straight to the compressor 2 but along the sound insulating plate 9 along with the sound insulating plate 9.
To the outer periphery of the compressor 2 and guides the ventilation gap 10 between the compressor 2 and the sound absorbing felt 11 upward, so that the heat of the compressor 2 is taken and the heat is sucked from the large opening 7a of the partition plate 7 to the condenser 3 side and effectively conveys the heat. It is a thing.

Since the sound emitted from the compressor 2 is doubly surrounded by the sound absorbing felt 11 and the partition plate 7, the sound emitted into the room is small, and the opening 5a provided in the lower plate 5 is a sound insulating plate. Since the diameter is smaller than 9, the direct sound does not leak to the outside of the lower surface plate 5, and the sound is attenuated and emitted, so that the sound insulation effect is enhanced.
