Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filter device suitable for an air inlet of an air conditioner installed in an indoor artificial ski resort, for example.

[0002]

2. Description of the Related Art In recent years, the development of indoor artificial ski resorts where skiing is possible is being promoted throughout the year. The indoor artificial ski resort has a structure in which, for example, artificial grass is laid on a sloping floor surface indoors, and artificial snow made by an artificial snowmaking device is deposited on the artificial grass.

In order to maintain a good quality snow surface in an indoor artificial ski resort, it is necessary to maintain a constant low temperature in the ski resort, and for that reason, it is essential to sufficiently ventilate the ski resort. . Such ventilation in the ski area is performed by sucking air in the ski area from suction ports provided at a plurality of locations on the wall surface of the building through a duct of an air conditioner connected to the suction ports.

[0004]

What is important in the ventilation in the artificial ski resort is that the
This is to prevent artificial snow floating in the air during snowmaking from being sucked into the duct together with air from the suction port. Inhaling snow with air causes the snow to adhere to and build up on ducts and air conditioners, improving ventilation efficiency and heat exchanger performance.
This may cause a decrease in efficiency and a failure of the air conditioner.

In order to prevent the above-mentioned problems, a filter may be attached to the air suction port of the air conditioner duct. Since the particles of artificial snow are extremely small, this filter cannot prevent its suction unless it is a filter with a small mesh. However, since artificial snow has moisture, if a filter with a small mesh is attached, artificial snow will immediately adhere to the filter and cause clogging, resulting in loss of filter function in a short time and deterioration of ventilation performance. A problem arises.

Therefore, an object of the present invention is to solve the above-mentioned problems, to reliably prevent the inhalation of powdery particles such as artificial snow, which are small in size and are liable to be moist, and to prevent clogging. It is to provide a filter device that does not occur.

[0007]

Means for Solving the Problems The inventors of the present invention have conducted extensive studies to solve the above-mentioned problems. As a result, an endless continuous movement type filter having a filter body made of a fluororesin fiber having excellent water repellency is provided on the front surface of the air suction port, and it is rotatable so as to come into contact with both sides of the filter body. It has been found that, by providing a pair of brush rolls, the endless continuous movement type filter can reliably prevent the intake of artificial snow or the like from the suction port and the adhesion of artificial snow or the like to the filter.

The present invention has been made on the basis of the above findings, and is a filter body made of a fluororesin fiber, which is provided on the front surface of the air suction port of an air conditioner duct so as to cover the air suction port. A pair of endless continuous movement type filters having a filter body of the endless continuous movement type filter, which is provided so as to be in contact with both sides of the filter body of the endless continuous movement type filter and which rotates in a direction opposite to the moving direction of the filter body. It is characterized in that it is composed of a brush roll.

Next, the present invention will be described with reference to the drawings. 1 is a schematic plan view showing one embodiment of a filter device of the present invention, FIG. 2 is a sectional view taken along line AA of FIG. 1, FIG. 3 is a schematic perspective view thereof, and FIG. 4 is an enlarged schematic perspective view of a filter portion. Is. As shown in the drawing, an endless continuous moving filter 3 is provided on the front surface of the air suction port 2 of the air conditioner duct 1 so as to cover the air suction port 2 entirely.

The endless continuous movement type filter 3 has a filter main body 4 made of fluororesin fiber having a mesh of, for example, about 60 mesh and excellent in water repellency, and a front surface of the air suction port 2 around which the filter main body 4 is wound. Roller 5 provided on both sides and rotatable about its axis, and chains 7, 7'attached to each of the upper end edge and the lower end edge of filter body 4 via a plurality of attachment fittings 6, 7 and 7'are meshed with sprockets 8 and 8'provided on both sides of the filter body 4. By rotating the sprockets 8 and 8 ′ by the motor 9, the filter body 4 made of fluororesin fiber is continuously moved in the arrow direction through the chains 7 and 7 ′.

A pair of brush rolls 10, 10 are sandwiched between the filter main body 4 which moves as described above and the front side of the air suction port 2 so that both sides of the filter main body 4 are in contact with each other. 'Is placed. Brush roll
Each of 10 and 10 'is made of horsehair or nylon, for example, and its axis extends in the entire height direction of the filter body 4. A motor 11 rotates each of the brush rolls 10 and 10 ′ in a direction opposite to the moving direction of the filter body 4. 12 is on the front side of the endless continuous movement type filter 3,
It is a protective panel provided at a predetermined distance from the filter body 4.

[0012]

Since the device of the present invention is constructed as described above, if it is installed in the suction port 2 of the air conditioner duct 1 of the indoor ski resort, the suction port 2 will be used for ventilation.
When sucking the air in the field from the inside, the filter body 4 made of the fluororesin-based fiber of the endless continuous movement type filter 3 surely prevents the artificial snow from being sucked from the suction port 2 and adheres to the filter body 4. The artificial snow thus formed is immediately removed by the rotating brush rolls 10 and 10 '. Therefore, according to the device of the present invention, the function of the filter body 4 is not lost, and the suction of artificial snow from the suction port 2 can be reliably prevented.

[0013]

As described above, according to the filter device of the present invention, it is possible to reliably prevent the inhalation of powdery particles such as artificial snow, which are small in size, are moist and easily adhere, and Industrially useful effects can be obtained without causing clogging.
