Abstract

PURPOSE:To blow off humidified cool air from the front surface of the fan in summer and blow off the humidified cool air from the upper surface of the fan in winter to permit to use the fan as a humidifying machine by a method wherein air blow-off ports are arranged on the front surface and the upper surface of the outer frame of the fan and the direction of air is blown off forwardly or upwardly. CONSTITUTION:When the fan 4 is rotated, air is sucked through the air suction port 9 on the outer frame 1 and is passed through a humidifying filter 6, suspended between a pair of rollers 5 and moved by a small size motor 7 while the lower end thereof is immersed in the water of a water tank 8 in order to be fed with water, so as to be humidified and cooled, thereafter, arrives at an air blow-off flow path 11. The air is blown off through the blow-off port 2 at the front surface of the outer frame in summer to provide cool air feeling while the air is blown off through the blow-off port 3 at the upper surface of the outer frame 1 by the control of the airflow deflecting vanes 10 and the air may be utilized for humidifying the inside of the room without providing human bodies with the cool air feeling.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an evaporative cooling fan that generates cold air using the latent heat of vaporization of water.

Conventional technology In general, conventional evaporative cooling fans blow out cold air from the front, and even if they have wind direction blades, they can only be controlled within a limited range of the front. There were times when I felt cold against my body. Therefore, in order to use the NAyR as an evaporative cold humidifier in the summer and as an evaporative humidifier in the winter, there was a demand for a drastic expansion of the control range of the wind direction.

However, with the conventional technology, as shown in FIG. 3, only a wind direction range A (a limited range in front of the outer frame) can be obtained for the evaporative cooling fan in summer.

Problems to be Solved by the Invention In this conventional configuration, the aim was to provide a cool feeling in the summer, so the air outlet was only in the front of the outer frame, and the wind direction was limited to a limited area in the front. Therefore, when used as a humidifier in the winter, the cold air hits the bodies of people living indoors, hindering the heating effect.

The present invention solves these problems, and when used as a humidifier in the winter, it prevents cold air from hitting the body of a person living indoors, and uses the evaporative cooling fan A in the summer and the humidifier in the winter. The purpose is to provide an evaporative cooling fan that can be used throughout the rainy season.

Means for Solving the Problems In order to solve this problem, the present invention includes an outer frame, a water tank disposed at the inner bottom of the outer frame, and an endless belt-like structure having one end inserted into the water tank. Supported times li+1
a humidifying filter, a blower disposed in an upper part of an outer frame, an air outlet provided in the outer frame, and a wind direction vane provided in an air blowing passage from the blower; Air outlets are arranged on the front and upper surfaces of the outer frame, and the wind direction is selectively controlled to the front and upper surfaces by the wind direction blades.

With this configuration, the air that has been humidified and cooled by the humidifying filter is blown through the outlet on the front of the outer frame in the summer, giving a feeling of cold air to the body, and in the winter, the air is blown through the outlet on the top of the outer frame by controlling the wind direction blades. This allows for more air to be blown and can be used for indoor humidification without giving the body a feeling of cold air.

EXAMPLE Below, an example of the present invention will be explained using the drawings (Figs. 1 and 2).
The explanation will be based on Figure).

In the figure, 1 is an outer frame, 2 is a front air outlet provided on the upper front surface of the outer frame 1, 3 is an upper air outlet provided on the upper front end of the outer frame 1, and 4 is an air outlet provided on the upper part of the outer frame 1. A blower is installed. A pair of rollers 5 suspends an endless belt-shaped humidifying filter 6, and the humidifying filter 6 is rotated by a small electric motor 7. Reference numeral 8 denotes a water tank disposed at the inner bottom of the outer frame 1, into which one of the rollers 5 and the lower ends of the humidifying filter 6 are inserted to receive water supply. 9 is an air suction port provided in the outer frame 1; 10 is a wind direction blade, which is rotatably attached to the front air outlet 2 located in the air blowing passage 11;
It is supported and has a movable range up to near vertical direction.

In the above configuration, when the blower 4 rotates, the outer frame 1
Air intake port 9. The air is suspended by a pair of rollers 5 and rotated by a small electric motor 7, and passes through a humidifying filter 6 whose lower end is inserted into a water tank 8 to receive water, where it is humidified and cooled, and the air is It reaches the blowout channel 11. At this time, when used as an evaporative cooling fan in the summer, the air is blown in the wind direction range B from the front air outlet 2 of the outer frame 1 by adjusting the horizontal direction of the wind direction Hio that is supported in the air blowing passage 11. can do. The air flow at this time is indicated by b. Also, when using it as a humidifier in winter, please set the wind direction to 9.
By changing 910 to a near-vertical direction, the air flow changes from C to C in the figure, and air is blown upward from the upper air outlet 3 of the outer frame 1.

As described above, according to this embodiment, by expanding the wind direction range to the near vertical direction and providing the air outlets 2 and 3 on the front and top surfaces of the outer frame, it is possible to switch the wind direction from the front to the top. Therefore, in the summer, the fan can be used as a single vaporization cooling fan that blows humidified cold air from the front, and in the winter, it can be used as a humidifier that humidifies the room without directing the humidified cold air to the human body.

Effects of the Invention As described above, according to the present invention, by expanding the wind direction range and providing the air outlet on the front and top surfaces, the evaporative cooling J
l! It is possible to add not only the function as a humidifier but also the function as a humidifier, which has a great practical effect.
