Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to an air conditioner having a humidifying unit.

[0002]

2. Description of the Related Art A conventional air conditioner having a humidifying unit is disclosed in Japanese Utility Model Publication No. 4-26829 (F24F1 / 0).
In 2), a steam outlet is provided at the top of the main body case,
A straight evaporating cylinder that evaporates the water supplied from the water tank in the main body case, and a steam guiding cylinder that guides the steam generated in the evaporating cylinder to the steam outlet are arranged vertically, and from the bottom of the steam guiding cylinder An annular rib smaller than the inner diameter of the evaporating cylinder and protruding downward is provided concentrically. In such an air conditioner, steam evaporated by boiling in the evaporation cylinder is condensed in the steam guide cylinder and the like, so that the condensed water is dropped directly from the ribs onto the water surface in the evaporation cylinder, and the steam is vaporized. This prevents the generation of strong evaporation noise due to instantaneous evaporation of the dew condensation water from the inner wall of the guide cylinder to the inner wall of the evaporation cylinder.

[0003] However, the boiling sound in the evaporating cylinder is generated when air bubbles are blown in the evaporating cylinder, and the air bubbles grow large toward the center portion. In the air conditioner having the opening on the side, a loud boiling sound leaks into the room through the opening, giving a user discomfort.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to provide an air conditioner which can eliminate evaporation noise and reduce boiling noise leaking into a room.

[0005]

Means for solving the above problems include an evaporating cylinder disposed substantially vertically in a main body case, a heating section for heating water supplied into the evaporating cylinder, and the evaporating cylinder. A steam guide tube that is connected to an upper portion of the evaporator and guides steam generated in the evaporator tube to a steam outlet provided in the main body case, and a sound insulation plate is provided between the heating unit from a lower portion of the steam guide tube. On the lower surface of the sound insulating plate, an inclined surface which is inclined downward toward the center of the evaporating cylinder is provided, and holes are provided on the inclined surface except for the center of the sound insulating plate. Thus, while reducing the leakage of a large boiling sound from the central portion, the condensed water generated in the guide tube is guided from the hole of the sound insulating plate to the central portion of the evaporating tube by the inclined surface.

In the above structure, it is desirable to provide a projection protruding downward at the center of the sound insulating plate. As a result, the dew water guided to the center of the evaporating cylinder travels along the projection and falls directly from the tip of the projection onto the water surface of the evaporating cylinder.

It is preferable that an inclined surface which is depressed downward is formed on the upper surface of the sound insulating plate. As a result, the condensed water generated in the steam guide tube by the inclined surface is guided to the center side, and can be smoothly collected in the evaporator tube through the hole.

[0008] It is desirable that the inclined surface on the upper surface and the inclined surface on the lower surface of the sound insulating plate are substantially parallel to each other, and the protrusion protrudes from an extension of the inclined surface on the lower surface. This allows
Even if the sound insulation plate is made of resin with the inclined surface on the upper surface and the inclined surface on the lower surface of the sound insulation plate being substantially parallel to each other, the inclined surface and the inclined surface are stuck together at the time of assembling the sound insulation plate. Thus, it is possible to prevent the plurality of sound insulation plates from being supplied in an overlapping state by the projections.

A case where humidification is performed by the air conditioner having the above configuration will be described.

Press the operation switch of the operation unit (not shown),
When the humidifying operation is performed, the compressor 16 of the dehumidifying section 7 is stopped, and only the blower 14 operates. Then, in this state, the heater 28 in the evaporation cylinder 26 is energized, and the water in the evaporation cylinder 26 is heated. The heated water eventually boils and becomes steam, and rises in the evaporating cylinder 26. And sound insulation board 3
7 is guided to the steam guide cylinder 29, and the inner cylinder 31
Is blown out into the outer cylinder 32 from the steam hole 33. And
This steam is mixed with air blown by the blower 14 introduced into the outer cylinder 32 from the air inlet nozzle 34, cooled, and blown out from the steam outlet 36 as steam having a temperature that does not cause burns.

At this time, when the steam is cooled in the steam guide cylinder 29, dew condensation water is generated. The condensed water reaches the sound insulating plate 37 along the inner wall of the steam guide tube 29. Condensed water that has reached the sound insulating plate 37 is formed on the inclined surface 3 of the upper surface of the sound insulating plate 37.

Since a is formed, the dew condensation water is guided toward the center of the sound insulating plate 37. The condensed water guided to the central portion is guided to the projection 39 without stagnation at the central portion, and the projection 3
9 directly falls on the water surface of the evaporating cylinder 26. Therefore, it is difficult for the dew condensation water to be transmitted to the inner wall of the evaporating cylinder 26, and it is possible to prevent the generation of the evaporation noise.

Further, since the sound insulating plate 37 shields the central portion, a large boiling sound generated in the central portion of the evaporating cylinder 26 is once interrupted by the sound insulating plate 37 and leaks out of the main body case 1. Boiling noise is reduced.

By forming an inclined surface 37b depressed downward on the upper surface of the sound insulating plate 37, the condensed water generated in the steam guide cylinder 29 is guided to the center side of the sound insulating plate 37 by the inclined surface 37b. The gas can be smoothly collected in the evaporating cylinder 26 through the hole 38.

Further, the inclined surface 3 on the upper surface of the sound insulating plate 37
7b and the inclined surface 37a on the lower surface of the
9 protrudes from the extension of the inclined surface 37a,
The inclined surface 37b on the upper surface and the inclined surface 37a on the lower surface of the sound insulating plate 37
When the sound insulating plate 37 is made of resin and is easy to mold when the sound insulating plate 37 is made of resin,
a and a plurality of sound insulation plates 37
Can be prevented from being supplied in an overlapping state by the protrusion 39, and an assembly error can be prevented.

Therefore, it is possible to prevent the dew condensation water from being transmitted to the inner wall of the evaporating cylinder and to prevent the generation of the evaporating noise while reducing the leakage of the loud boiling noise from the central part.

According to the second aspect of the present invention, the dew water guided to the center of the evaporating cylinder travels along the projection without stagnation at the center, and falls directly from the tip of the projection to the water surface of the evaporating cylinder.
