Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention relates to an air conditioner with a humidifying device that prevents water droplets from falling from a humidified air outlet of an air conditioner having a humidifying function.

[Technical background of the invention and its problems]

In conventional air conditioners with a humidifying function, water droplets or water vapor scattered from the humidifier adhere to the humidified air outlet, and depending on the conditions, these water droplets may fall into the room and damage the floor or other objects. It had the disadvantage of getting wet.

[Purpose of invention]

This invention was made in consideration of the above circumstances, and its purpose is to provide an air conditioner with a humidifying device that eliminates the above drawbacks and prevents water droplets from falling from the humidifying air outlet. It is something.

[Summary of the idea]

In this invention, the installation height of the humidified air outlet provided below the front panel of the air conditioner is set higher than the installation height of the heat exchange air outlet. The heat exchange air, which exchanges heat with the exchanger and becomes high in temperature and is blown out from the heat exchange air outlet and tries to rise, can roll up water droplets attached around the humidifying air outlet from below the humidifying air outlet and vaporize them. can.

[Example of idea]

An embodiment of this invention will be described below with reference to the accompanying drawings. In the figure, 1 is the main body of an indoor unit of a split type air conditioner, and a front panel 2 is provided on the front of this main body 1. A suction port 3 for indoor air is provided at the upper front of the front panel 2. A blowout port 4 for blowing out heat exchange air is provided below the suction port 3. An ultrasonic humidifier 5 is arranged on one side inside the main body 1. A vertically elongated air outlet 6 as a humidified air outlet is provided on the front surface of the humidifier 5. Further, a ventilation inlet 7 is provided protruding from the side of the humidifier 5. A ventilation guide 8 is provided in the ventilation inlet 7 so as to face diagonally upward. Further, a heat exchanger 9 is provided on the side of the humidifier 5. A drain pan 10 is provided below the heat exchanger 9. A cross-flow fan 11 is provided below the back surface of the heat exchanger 9.
The vicinity of the end of the cross-flow fan 11 overlaps with the air inlet 7 of the humidifier 5. A fan casing 13 integrally formed with a heat insulating casing 12 is provided on the back side of the cross-flow fan 11, and the fan casing 13 which is integrally formed with the heat-insulating casing 12 guides the heat exchange air that has passed through the heat exchanger 9 to the air outlet 4 and blows it out into the room. The heat exchange air is guided to the ventilation inlet 7 along the ventilation guide 8. A water supply tank 5a is placed on the top of the humidifier 5, and its water supply port body 5b is fitted into a water supply port 5c provided on the top surface of the humidifier 5. An opening 14 is formed in the front panel 2 at a position corresponding to the water supply tank 5a, and the water supply tank 5 is inserted through this opening 14.
A can be attached and detached. This opening 14
An opening 15 is formed in the lower part of the humidifier 5, and the air outlet 6 of the humidifier 5 projects from the surface of the opening 15. The blower outlet 6 is arranged laterally parallel to the blower outlet 4, and its center height is offset above the blower outlet 4 by an amount h, as shown in FIG. Further, an uneven surface 16 having fine unevenness is provided on the surface around the opening 15 to prevent water droplets adhering to the outside of the air outlet 6 from collecting on the uneven surface 16 and falling directly into the room. It's summery. Instead of this uneven surface 16, the flocked part 1
6a may be provided to allow water droplets to collect therein. On the other hand, an electrical component box 17 is provided inside the main body on the opposite side of the humidifier 5 and water supply tank 5a. The electrical parts box 17 has a display section 17a and an operation section 1.
7b, and an operation box 17c is suspended below the operation section 17b via a cord. The right side of the front box 2 corresponding to the electrical parts box 17 is provided with openings into which the display section 17a and the operation section 17b are fitted. Note that the air outlet 6 as a humidified air outlet of the humidifier 5
protrudes from the surface of the front panel 2, so that the heat exchange air blown out from the laterally adjacent air outlet 4 serving as the heat exchange air outlet winds the water droplets attached around the air outlet 6 upward. The effect of this embodiment is that water droplets are blown up and vaporized to prevent water droplets from falling directly into the room.

In addition, an uneven surface 16 or a flocked portion 16a is formed on the front panel 2 around the base of the air outlet 6 to retain water droplets attached around the air outlet 6 and to evaporate when the room becomes dry. This has the effect of preventing it from falling indoors.
Furthermore, since the electrical parts box 17 is housed on the opposite side of the humidifier 5 that stores water inside and the water tank 5a, there is no risk of insulation failure in electrical parts even in the event of water leakage. .

Next, the effect of this invention will be explained. When the air conditioner starts humidifying operation, the crossflow fan 11
Indoor air is drawn from the air intake port 3 on the front panel 2 to the main body 1.
Inhale inside. After the air sucked into the main body 1 passes through the heat exchanger 9 and undergoes heat exchange, most of the air is blown out into the room from the air outlet 4. A part of the heat exchange air is blown into the humidifier 5 from a ventilation inlet 8 protruding from the side of the humidifier 5, and fine water droplets generated by ultrasonic vibrations in the humidifier 5 are removed from the air outlet. Humidify the air blowing chamber from step 6. Also, among the fine water droplets that are blown out, those that come into contact with the air outlet 6 adhere to the outside, but these are blown out from the air outlet 4 that is adjacent to the air outlet 4 and is disposed downwardly than the air outlet 6. This prevents water from being blown up by the heat exchange air, vaporizing, and falling directly into the room, and as shown in the graph of Figure 6, the larger the amount h that the air outlet 6 is deviated above the air outlet 4, the more water droplets will adhere to it. Experimental results showed that the amount decreased.

Next, FIGS. 7 to 10, in which the same components in FIGS. 1 to 5 are given the same reference numerals, show other embodiments. The air outlet 6 of the humidifier 5 is mounted at a high position H, as shown in FIG. 6, so that water droplets attached to the inner surface of the humidifier 5 can easily return to the inner surface of the humidifier 5. However, there is a drawback that the height of the water tank 4 becomes lower and the tank capacity becomes smaller. Therefore, in this embodiment, as shown in FIG. ensure that Furthermore, as shown in FIG. 9, the partition wall 18
A drain introduction groove 2 is provided at the bottom of the fan casing 13 to collect water droplets that have fallen from around the air outlet 6 to the outside of the partition wall 18.
It is designed to lead to 0. By doing this, water droplets that have fallen from the outlet 6 are prevented from overflowing and falling into the room from the outlet 6, and the water droplets that have been introduced into the drain introduction groove 20 are re-evaporated by the heat exchange air. can be blown into the room to humidify the room.

FIG. 10 shows yet another embodiment, in which the partition wall 1
Attach the drain guide 21 to the outside of the partition wall 1
This structure is configured so that water droplets falling on the outside of the body 8 are introduced into the bottom surface 1a of the main body 1 provided with the flocked portion 22, and the same effect as shown in FIG. 9 can be obtained.

[Effect of idea]

As explained above, in this invention, the humidified air outlet is biased upwards than the heat exchange air outlet and is provided on the front panel to humidify the room, so that the air is blown out from the adjacent heat exchange air outlet. The heat exchange air has the effect of blowing up water droplets adhering to the outside of the humidifying air outlet and vaporizing them, thereby preventing them from falling into the room.
