Abstract

(57) [Abstract] [Purpose] In order to constantly supply clean air to the room by removing even fine dust with an inlet grill attached to the air intake of air conditioning ducts and air conditioning equipment of various buildings. The purpose is to The suction grill according to the present invention is characterized in that a reticulated conductor 3 to which a high voltage is applied and a metal grid 1 are arranged in parallel, and a filter medium 2 made of an insulating material is sandwiched between them. .

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to the structure of air conditioning ducts of various buildings and the air intake of air conditioning equipment.

[0002]

[Prior Art]

 As shown in FIG. 3, the conventional inlet grill is mainly for the purpose of decorating the room, and has an outer frame for fixing a grid-like or slit-like metal a and a coarse filter b for collecting relatively large dust. It was composed of c and. d shows a suspension bolt. On the other hand, as shown in FIG. 4, an air purifier that applies a high voltage by sandwiching a filter material made of an insulating material with a net-shaped conductor has a housing and an air suction fan, and is mainly mounted on the ceiling.

[0003]

[Problems to be solved by the device]

 And since the inlet grill is usually attached to the air intake of the air conditioning duct or the air conditioning equipment, it is equipped with coarse filter media with low pressure loss so as not to reduce the air volume, but fine dust passes through. As a result, fine dust accumulates in the air-conditioning ducts and air-conditioning equipment, leading to the growth of mold and bacteria, which causes polluted air to be supplied indoors. Therefore, there is a problem that the air must be purified separately. On the other hand, a dielectric air purifier that applies a high voltage is structurally expensive because it includes a suction fan and a fan drive motor, and it has a problem that it is costly to install on the ceiling.

[0004]

[Means for Solving the Problems]

 The present invention has been made in view of the above-mentioned problems, and takes advantage of the advantages of the dielectric air cleaner, uses the inlet grille as a net-shaped conductor, generates an electric field, and has a coarse filter medium placed there. Was charged, and even fine dust was strongly collected.

[0005]

[Action]

 With this configuration, even fine dust is removed at the suction port to prevent accumulation of dirt in the air conditioner, and since the coarse filter media is used, the pressure loss is low and the air volume is not reduced. In addition, since the air conditioning duct and air conditioning equipment are equipped with a blower fan, the blower fan and its drive motor, which were required in the dielectric air purifier, are not required, and the housing for fixing them is also unnecessary. Furthermore, since the inlet grill itself is composed of a metal grid or slit, these can be used as a mesh conductor.

[0006]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. The suction grill has a shape having an insertion / extraction opening 8 for the filter medium 2 on the side surface so that the filter medium 2 made of an insulating material can be sandwiched by the metal grid 1 and the mesh conductor 3, and the entire filter medium is formed. For convenience of replacement of 2, the hinge 7 is used to fix it openably and closably, and it is fixed to the frame 10. The frame 10 is attached to the ceiling by the hanging bolts 11 with the lower surface aligned with the ceiling. There is.

The reticulated conductor 3 is attached to the suction inlet grill body via the insulator 4, and a high voltage is applied from the high-voltage source 5 through the high-voltage cable 6.

The operation will be described next. When the air cleaner is used, a high voltage is applied to the mesh conductor 3 from the high voltage power supply 5 through the high voltage cable 6 so that the metal grid 1 and the mesh conductor 3 are connected to each other. An electric field is generated, and the fibers of the filter medium 2 are charged by electrostatic induction in the electric field, and it is possible to strongly collect even fine dust in the passing air. This dust collection effect prevents the accumulation of fine dust in the air conditioning ducts and air conditioning equipment, prevents the growth of mold and bacteria, and keeps the indoor air clean.

[0009]

[Effect of the device]

 This invention is constructed as described above, and it is possible to prevent air pollution in the room due to internal pollution of air conditioning ducts and air conditioning equipment, which was conventionally caused by installing an air intake port, and install an air purifier again in the room. There is no waste. . Further, since air is already sucked in the suction port grill of the present invention, those devices are not required, and the cleaning of air can be achieved at a very low cost.
