Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a narrow portion in a part of the ventilation passage inside the machine, narrows and rectifies the air flowing in the ventilation passage, and reduces noise and noise. The present invention relates to a unit type air conditioner that prevents the occurrence of heat exchange and has excellent heat exchange efficiency.

[Conventional technology]

Conventionally, a unit type air conditioner such as a terminal air conditioner or a fan coil unit has a blower 2 installed in the lower part of the fuselage 1 as shown in the first figure.
A drain pan 5 and a heat exchange coil 3 are installed in the upper ventilation passage 4 with an appropriate distance between them, tilted forward or backward, or horizontally or vertically, and air is sucked in from the air inlet 10 via the blower 2. The heat exchange coil 3 exchanges heat to an appropriate temperature, and one outlet 11 supplies and distributes cold and warm air into the room.

[Problem to be solved by the invention]

However, in the case of the above-mentioned mechanism, the air from the blower 2 flows directly up the inside of the ventilation passage 4, and heat exchange is performed in the heat exchange coil 3 in an uneven body, which causes variations in the air flow. It has the disadvantage that it does not provide ideal heat exchange action, and is also considered to be a source of noise. Furthermore, water droplets adhering to the coil surface dripped and wet the blower 2, causing trouble.

In view of these problems, an object of the present invention is to form a narrow ventilation passage 6 in a part of the ventilation passage 4 using the width of the drain pan 5, and to form a narrow ventilation passage 6 within the narrow ventilation passage 6. To provide a unit type air conditioner which narrows the airflow flowing through the air conditioner, always keeps the wind speed at the bottom, and further completely prevents water droplets from entering the blower 2.

[Means to solve the problem]

In order to achieve the above object, the unit type air conditioner according to the present invention has a drain pan 5 having a larger diameter than the outlet 2' and wider than the center of the body above the outlet 2' of the blower 2. A narrow ventilation passage 6 is formed in one side of the ventilation passage 4, and a partition mechanism 7 is provided above the drain pan 5. It is characterized in that a mechanism such as a heat exchange coil 3 is integrally provided on the upper part of the heat exchanger 7.

Furthermore, in the above structure, the lower bottom surface shape of the drain pan 5 is formed into an inclined surface a in an appropriate direction such as the front, rear, or both sides, thereby naturally smoothing the air flow in the ventilation passage 4 into the narrow ventilation passage 6. By directing the current to the current, a more effective rectifying function can be achieved.

[Effect]

The present invention has the above configuration, and the air blown from the blower 2 passes through the air passage 4 between the discharge port 2' and the drain pan 5, and the air speed is temporarily narrowed in the narrow air passage 6 to maintain a constant pressure. Add this to heat exchange coil 3
The air is diffused into the front passageway of the coil and distributed substantially uniformly throughout the coil, exchanging heat to an appropriate temperature while providing a predetermined amount of cold or warm air into the room from the air outlet 11.

In addition, water droplets in the heat exchange coil 3 flow through the partition mechanism 7 and naturally flow into the drain pan 5, and the air blower 2
Prevents water droplets from falling on the surface.

Further, according to the present invention, by arranging the humidifying device 8 in the space of the drain pan 5, it is possible to bring about an appropriate humidity distribution in addition to the above-mentioned ventilation.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. 1 is a fuselage body having an inlet 10 and an outlet 11 provided at predetermined locations such as the upper, lower, rear, front, side, etc. A blower 2 is installed at the bottom. A drain pan 5 is placed in the upper ventilation passage 4 of the discharge port 2' of the blower 2 with a certain distance therebetween.
The drain pan 5 has a width b that is larger in diameter than the discharge port 2' of the blower 2, is at least wider than the center of the fuselage 1, and is biased toward either the front or the rear with the center position inside the fuselage 1 as an axis. By arranging the drain pan 5 close to each other, it is possible to easily form a narrow ventilation passage 6 at the front and rear sides of the drain pan 5.

Note that the bottom shape of the lower part of the drain pan 5 can be made into any bottom shape, such as forward slope as shown in the figure, rearward slope, front and rear both sides slope, etc. You may be able to use something. In addition, the drain pan 5 is provided with a partition mechanism 7, a spare drain pan, and other mechanisms, and the heat exchange coil 3 is installed to tilt forward, and a humidifying device such as a humidifying pipe or a humidifier is installed in the surplus space of the drain pan 5. 8 will be attached.

Reference numeral 9 in the figure indicates a drain port.

[Effect of idea]

As described above, in the present invention, the width b of the drain pan 5 is made larger in diameter than the discharge port 2' of the blower 2, and the drain pan 5 is biased toward either the front or rear side of the ventilation passage 4 to form a narrow ventilation passage 6. By forming the blower 2
Naturally constricting the air flow in the narrow air passage 6,
The wind speed is rectified at a constant rate, and the air is applied and distributed almost evenly over the entire surface of the heat exchange coil 3, making the heat exchange efficiency extremely good, as well as eliminating noise and sound, and providing an excellent sound deadening function. have. Moreover, in the present invention, since the width b of the drain pan 5 is larger in diameter than the discharge port 2' of the blower 2 as described above, it is possible to prevent damage caused by water droplets falling on the blower 2, and in particular, Utilizing the extra space of the drain pan 5, the partition mechanism 7 as well as the humidifier 8 can be used for preliminary draining.
This is a very convenient invention, as it allows for extremely easy accommodation or installation of various mechanical devices that were conventionally said to have difficulty in installation space.

In addition, in the present invention, by making the front panel open and close, not only the blower 2 but also all the internal mechanical devices such as the drain pan 5' and the heat exchange coil 3 are exposed, which makes it necessary to inspect, clean, and replace them. It also has the advantage of being able to perform various tasks simply and easily.

It goes without saying that the present invention can be widely used in any type of air conditioner, such as I-type, L-type, etc., in which the air passage has the above-mentioned shape.
