Install the vaporization type humidifier without impairing the air volume. In an air conditioner in which the wind that has passed through a heat exchanger 2 is converted into a substantially right-angled direction, an evaporative humidifier 3 is arranged in a wind passage downstream of the heat exchanger 2. Further, separate drain pans 4 and 5 are provided below the heat exchanger and below the vaporizing humidifier so that drain water discharged from the drain pan 5 drainage port of the vaporizing humidifier 3 enters the drain pan 4 below the heat exchanger 2. The drainage channel 6 is provided.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner having a vaporizing humidifier.

[0002]

2. Description of the Related Art In the prior art, for example, Japanese Patent Publication No.
As disclosed in Japanese Patent Publication No. 40, in an air conditioner having an evaporative humidifier that allows air to pass through a moistened humidifying element and spontaneously evaporates water by utilizing sensible heat, the air conditioner drops from the humidifier. In order to receive the humidified water that has not completely evaporated, the drain pan under the heat exchanger is extended to the lower part of the humidifier, or a separate drain pan under the humidifier is installed to remove the drain water from each drain pan. Had been discharged.

[0003]

However, in the case of extending the drain pan among the above-mentioned conventional methods, there is no particular problem in the case of the type in which the wind passing through the heat exchanger travels almost straight, but there is no problem in exiting the heat exchanger. The wind is converted into a substantially right-angled direction.For example, in an air conditioner installed in a ceiling, a drain pan that extends below the vaporization type humidifier enters the air passage to create a resistance to the wind and the air flow of the air conditioner. Has the drawback of significantly reducing. For this reason, although there are measures such as increasing the size of the main body, there is a problem that the device becomes large and the manufacturing cost increases. Also, in an air conditioner in which a drain pan is provided for each of the heat exchanger and the vaporization type humidifier, and a drain port is provided for each, a drain pan drain pipe work is required for each, and installation work costs increase and the amount of work increases. There was a problem.

An object of the present invention is to mount a vaporization type humidifier without deteriorating the commonality of parts of an air conditioner, the humidification efficiency, and the air volume.

[0005]

The present invention has been made in order to achieve the above object. In the first invention, an air conditioner is provided in which the wind passing through a heat exchanger is redirected in a substantially right-angled direction. , A vaporization type humidifier is installed in the air passage on the downstream side of the heat exchanger, and separate drain pans are provided below the heat exchanger and below the vaporization type humidifier, and the drain pan outlet of the vaporization type humidifier is used. A drainage channel is provided so that the drain water can enter the drain pan below the heat exchanger. Further, in the second invention, the passage of the wind passing through the heat exchanger and having the wind direction changed on the upstream side of the vaporization type humidifier is narrower than the passage of the wind having the wind direction changed on the downstream side of the humidifier. What is done is summarized.

[0006]

[Operation] In an air conditioner in which the wind that has passed through the heat exchanger is redirected in a substantially perpendicular direction, an evaporative humidifier is installed in the wind passage on the downstream side of the heat exchanger, and In addition, a separate drain pan was installed below the vaporization type humidifier, and a drainage channel was provided so that drain water discharged from the drain pan drain port of the vaporization type humidifier enters the drain pan below the heat exchanger. It is possible to secure the amount of air flow that is changed on the upstream side and to use only one drain drain port to the outside. Further, since the air passage that passes through the heat exchanger and has its airflow direction changed on the upstream side of the vaporization type humidifier is narrower than the air passage that has its airflow direction changed on the downstream side of the vaporization type humidifier, the amount of air passing through the vaporization type humidifier is reduced. Therefore, the shape of the main body of the air conditioner can be made the same as in the case without the vaporization type humidifier.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An air conditioner according to the present invention will be described below with reference to the embodiments shown in the drawings. FIG. 1 shows the structure of an air conditioner in an embodiment of the present invention. In the figure, 1 is a blower installed in the main body of the air conditioner. A heat exchanger 2 is provided in the vicinity of the air outlet of the blower 1, and a vaporizing humidifier 3 is provided in opposition to the heat exchanger 2. Set up. Then, under the heat exchanger 2 and the vaporization type humidifier 3, drain pans 4, 5 are respectively provided.
Place and receive drain water respectively. Further, a drainage channel 6 is installed from the drain pan 5 to the drain pan 4 so that the drain water of the drain pan 5 is guided to the drain pan 4.

As shown in the figure, the vaporization type humidifier 3 is provided with a pressure reducing valve 9 and a solenoid valve 10 so that humidifying water can be supplied from a water supply port 8 through a pressure reducing valve 9 and a solenoid valve 10.

Therefore, in the heating operation of the air conditioner requiring humidification in this embodiment, the air sent from the blower 1 is heat-exchanged by the heat exchanger 2 when passing through the heat exchanger 2. It becomes hot wind, and a part of it passes through the gap between the heat exchanger 2 and the vaporization type humidifier 3, and a part of it also becomes the vaporization type humidifier 3.
Pass through. This high-temperature air is humidified as it passes through the vaporization-type humidifier 3, and this humidified wind is mixed with the high-temperature wind that has passed through the heat exchanger on the downstream side of the vaporization-type humidifier 3 and is blown out from the blowout panel 7. Blown out.

Here, for the humidification of the vaporization type humidifier 3, the humidification water is passed from the water supply port 8 through the pressure reducing valve 9 and the electromagnetic valve 10, and although not shown, inside the vaporization type humidifier 3 is humidified from above the internal humidification element. Water is added by dripping water, allowing air to pass through the moistened humidifying element, and naturally evaporating water by utilizing sensible heat.

[0011]

The air conditioner of the present invention is an air conditioner in which the wind passing through a heat exchanger is redirected in a substantially right-angled direction, and an evaporative humidifier is provided in the air passage downstream of the heat exchanger. Along with the installation, separate drain pans are installed below the heat exchanger and below the vaporization type humidifier, so that the drain water from the drain pan drain port of the vaporization type humidifier enters the drain pan below the heat exchanger. By providing the above, it is possible to secure the air volume that is changed in the wind direction on the upstream side of the vaporizing humidifier, and to provide only one drain drain port to the outside. In addition, the passage of the wind that passes through the heat exchanger and whose direction is changed on the upstream side of the vaporization-type humidifier is narrower than the passage of the wind that is changed on the downstream side of the vaporization-type humidifier, so that it passes through the vaporization-type humidifier. Secure the air volume to
The shape of the main body of the air conditioner can be made the same as in the case without the vaporization type humidifier.
