Abstract

PURPOSE:To prevent a large vortex generated in a whole room by providing a diffuser for diffusing the air in a substantially equal speed distribution substantially radially at two opposed sides of a wall and a floor or whole periphery, and providing a diffuser substantially at the center of the floor. CONSTITUTION:A diffuser 1 for diffusing in a substantially equal speed distribution substantially radially from horizontally to vertically is provided at two opposed sides of a corner in contact with a wall 6 and a floor 4 or a whole periphery, a suction port 3 is arranged substantially at the center 5 of a ceiling, and the diffuser 1 is coupled to the port 3 via a duct out of a room. Even if a temperature difference exists in the airs diffused from the two opposed sides of the corner in contact with the wall 6 and the floor 4 or the whole periphery, the air diffused from the diffuser 2 substantially at the center of the floor forms a stable rising air flow. Accordingly, an upward air flow distribution having small vortex can be realized in a whole room, thereby cleaning the air in the room with high efficiency upon self-rising of the contaminated air.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an air cleaning system that purifies room air with high efficiency.

[Conventional technology]

Conventional air purification systems are installed on walls (1) as shown in Figure 4.
Air outlets (14) with grilles that emit air in a substantially radial direction from the horizontal direction to the vertical direction and with a substantially uniform velocity distribution are arranged on two opposing sides or the entire circumference of the corner where the floor (16) contacts the air outlet (14). and a suction port (15) on the ceiling surface (l7).
It was configured to have . In the figure, (17) is a filter (20) that purifies the air sucked in from the suction port (l5) and sends it out again to the blowout port (14).

[Problem to be solved by the invention]

In conventional air purification systems, if there is a temperature difference between the air blown out from opposing outlets, a large vortex may be generated in the space, making it impossible to purify the air efficiently. Figure 4 shows a concrete example of conventional purification. If there is a temperature difference between the blown air A and B in the figure, and the blown air temperature at point 8 is higher than that at B, a large vortex will be generated in the space as shown in the figure, and as a result, dust, etc. will accumulate. The problem was that it was difficult to purify.

Another example of an air purification system is a clean room, but it cannot be applied to homes, offices, etc. because of its enormous air volume.

[Means to solve the problem]

In order to solve the above problems, the air cleaning system of the present invention has a substantially uniform velocity distribution in a substantially radial direction from the horizontal direction to the vertical direction on two opposing sides or the entire circumference of the corner where the wall and floor meet. An outlet for blowing out air is provided, the outlet is placed approximately at the center of the floor, and an intake port is placed approximately at the center of the ceiling.

[For production]

The air purification system configured as described above is equipped with outlets that blow out air in a substantially radial direction and with a substantially uniform velocity distribution on two opposing sides or on the entire circumference of the corner where the wall and floor meet. By providing an outlet at approximately medium heat, even if there is a temperature difference between the air blown from two opposing sides or the entire circumference of the corner where the wall and floor meet, the air coming out from the outlet located approximately in the center of the floor will Since it creates a stable upward airflow, it can prevent large vortices from occurring throughout the room.

〔Example〕

Examples will be explained using figures.

The air purification system of the present invention is installed on the walls (6) and floors (4) in a room normally used in a closed state, as shown in Figure 1.
) are provided on opposite sides or on the entire periphery of the corner where they touch, with air outlets (1) that emit air in a substantially radial direction from the horizontal direction to the vertical direction and with an approximately uniform velocity distribution, and an air outlet (2) is provided in the center of the floor. , the suction port (3) is located approximately in the center of the ceiling (5). Moreover, the above-mentioned blow-off port (1) and suction port (3) are connected by a duct (26) outdoors.

The duct (26) has a fan (8) and a filter (7) for collecting pollutants such as cigarette smoke. The above-mentioned air outlet (1) is equipped with a resistor such as felt having a large pressure loss, as shown in Fig. 2 (A), in order to blow air in a substantially radial direction and with a substantially uniform velocity distribution. (2
4>, or as shown in Figure 2 (B), the air outlet (1) is equipped with a grill (25) to make the wind direction radial and to make the air volume uniform. ing.

Also, instead of the circulation 2 as in the embodiment shown in Fig. 1, the outlet (1) and suction port (3) as in the illustrated example in Fig. 3 are
The outlet (l) and the inlet (3) may be brought into contact with the outside air and sucked and exhausted separately without being connected by a duct. In this way, air cleaning can be more complete.

〔Effect of the invention〕

The air purifying system of the present invention can be used even when there is a temperature difference between the air blown from two opposing sides or the entire circumference of the corner where the wall and floor meet due to the horizontal force explained above, from the air outlet located approximately in the center of the floor. Since the exiting air forms a stable upward airflow, an upward airflow distribution with small vortices can be achieved throughout the room. Therefore, combined with the self-raising power of contaminated air, the air in the room can be efficiently purified.
