Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an air conditioner used for industrial purposes, for example, a mounting structure of a humidifying device thereof.

[Conventional technology]

FIG. 4 is a front view of a conventional air conditioner of a ceiling-mounted exposed installation type, FIG. 5 is the same cross-sectional view, FIG. 6 is the same cross-sectional view, and FIG. 7 shows the air conditioner shown in FIG. FIG. 8 is a detailed cross-sectional view of the air outlet of the ultrasonic humidifier, which is a constituent, and FIG. 8 is a cross-sectional view of the conventional general ultrasonic humidifier shown in FIG.

In these figures, (1) is a Finch-Ube heat exchanger, (2) is a blower, (3) is a blowout grill, (4) is a drain pan, (5) is an air conditioner box, and (6) is the front. Bunny board, (7a)
Is an ultrasonic humidifier body having a humidification water layer portion (7f) and a vapor layer portion (7g), (7b) is an air inlet pipe for letting air into the ultrasonic humidifier body (7a), and (7c) is The air outflow pipe for letting out the air humidified by the ultrasonic humidifier body (7a) is shown. The arrow () indicates the flow direction of the air flow.

Next, the operation will be described. The air sucked in from the back side of the air conditioner box (5) passes through the blower (2) and the finch-Ube heat exchanger (1), and from the suction grille (3) to the air conditioner box (5). Is blown out in front of.

The ultrasonic humidifier body (7a) does not have a function to blow air, but as shown in FIG. 6, the air inlet (7d) is arranged on the upstream side of the finch-ube type heat exchanger (1). Since the air outflow pipe (7e) is arranged outside the air conditioner, the air inflow port (7d) and the air outflow port (7d) are set by the flow resistance of the air passing through the finch-Ube heat exchanger (1). There is a static pressure difference with 7e). Therefore, a part of the air blown by the blower (2) flows into the ultrasonic humidifier main body (7a), and the humidified air flows out from the air outflow pipe (7a) to obtain a humidifying effect.

[Problems to be solved by the invention]

The air outflow pipe (7c) of the ultrasonic humidifier of the conventional air conditioner is provided so as to horizontally pass through the front baffle plate (6), and the air humidified by the ultrasonic humidifier main body (7a) is It is usually in the state of supersaturated steam, and this steam is the air outflow pipe.
There was a problem that part of the water vapor was condensed while being guided to (7c), and this water droplet dripped from the outlet (7e).

The present invention has been made to solve the above problems, and an object thereof is to obtain an air conditioner in which condensed water of steam does not drip.

[Means for solving problems]

In this invention, an outer pipe inserted into the outside of the air outflow pipe of the humidifier is provided, one end of the outer pipe is projected outward from the tip of the air outflow pipe, and the other end of the outer pipe is placed above the drain pan. The above object is achieved by adopting a structure in which the other end of the outer pipe is inclined toward the one end of the outer pipe so as to have an upward slope.

[Action]

In this invention, the condensed water discharged together with the water vapor discharged from the outlet of the air outlet pipe is introduced into the air conditioner drain pan through the space formed between the outer pipe and the inner pipe, so that It prevents the drop of water drops.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. (1)
Is a Finch-Ube type heat exchanger for exchanging heat between the heat medium and the air to be conditioned, (2) is a blower for supplying the air to be conditioned to the heat exchanger (1), and (7a) is a humidifier main body, An ultrasonic humidifier is used in the example. (7f) is a humidifying water layer portion stored in the ultrasonic humidifier (7a), (7g) is a vapor layer portion of the steam generated by operating the ultrasonic humidifier (7a), 7b) is attached to the ultrasonic humidifier (7a),
One end thereof is an air inflow pipe opening to the vapor layer portion (7g), and the other end is provided with an inflow port (7d), and this inflow port (7d) is an air passage through which the conditioned air passes ( In 8), it is arranged on the windward side of the heat exchanger (1). (7c)
Is an air outflow pipe attached to the ultrasonic humidifier (7a), one end of which is an opening to the vapor layer part (7g), and the other end of the outlet (7e) is a front baffle plate. It is arranged in the outer tube (7h) which penetrates (6). Also, this outer tube
(7h) is installed at one end thereof, that is, the outlet (7j) is inclined so that the other end (7k) has an upward slope, and the other end (7k) at the bottom is the drain pan of the air conditioner. It is placed so that it is located above (4).

In the air conditioner configured as described above, the air taken in from the back surface of the air conditioner box body (5) is sent to the finch-hube heat exchanger (1) by the blower (2) to exchange heat. It is sucked out from the grill (3).

Water vapor generated by the ultrasonic humidifier (7a) is the air inflow pipe (7b).
Is mixed with the air flowing in from the air outflow pipe (7c) and flows out into the air-conditioned space.In the air outflow pipe (7c), condensed water in which a part of the steam is condensed is the air outlet (7e). ) Is discharged together with water vapor. The discharged water vapor is diffused into the air in the room through the outlet (7j) of the outer pipe, but when the condensed water exits the air outlet (7e), the outer pipe (7h) and the air outflow pipe (7c).
It falls into the space (7l) formed between the outer pipe (7h) and the outer pipe (7h), so that the condensed water does not go out from the outlet (7j) of the outer pipe. The outer pipe (7h) and the air outflow pipe (7
It is guided to the upper part of the drain pan (4) through the space between c) and falls into the drain pan (4).

In the above embodiment, the position of the outlet (7e) of the air outlet pipe (7c) is provided on the side of the outlet side space of the outlet grill (3), but it may be provided on the front side of the outlet grill. Alternatively, it may be provided outside the side surface (5a) of the box for an air conditioner.

[Effect of device]

As described above, according to the present invention, the outer pipe inserted into the outside of the air outflow pipe is provided, one end of the outer pipe is projected outward from the tip of the air outflow pipe, and the other end of the outer pipe is connected to the drain pan. Of the outer pipe, and the water is condensed in the air outflow pipe into the drain pan of the air conditioner because the water is condensed in the air outflow pipe from the other end of the outer pipe to the one end of the outer pipe. Therefore, the condensed water can be prevented from dripping from the air conditioner into the room or the like.
