JP2002263177A - Air purifier using charcoal - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide an air purifier constituted of charcoal and a light source, etc., for purifying air by generating natural convection by the temperature rise of the light source. SOLUTION: This air purifier using the charcoal is provided with an exhaust port 1 and an intake port 2 on upper and lower parts. The charcoal B is installed at the lower part, the light source A (electric appliances for AC100 V such as a light bulb and a discharge lamp) is installed at the upper part and a filter E whose materials are rushes, Japanese paper and a catalyst is installed in the middle.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a purifier for cleaning dirty air in a room, and more particularly to an air purifier using charcoal and a light source.

[0002]

2. Description of the Related Art As a conventional air purifier, forced exhaust by a fan, electric control by an inverter motor, etc.
Those having complicated mechanisms are widespread.

[0003]

In the prior art, manufacturing costs are high due to such a complicated mechanism, and as a result, retail prices are high.

In addition, since a motor or a fan is used, noise of 15 dB or more is generated, which causes discomfort, consumes a large amount of electric power, increases the cost of electricity, and increases running costs.

The present invention has been made in view of such problems of the prior art, and has as its object to purify air in a silent state by natural convection. .

[0006]

Means for Solving the Problems To achieve this object, the air purifier of the present invention is characterized by using charcoal and a light source as main components and not using any electric equipment such as a motor and a fan.

[0007]

Embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1, a light source A is provided above a device of a frame F having an exhaust port 1 and an intake port 2 above and below.
And put charcoal B below. When the power source is turned on and the light source A warms, air convection flows from below to above in the device. In the process of flowing the air, the air C contaminated by the charcoal B and the like is purified, and the purified clean air D is exhausted from above the device.

FIG. 2 shows an air purifier in which a filter E made of rush or the like is inserted between a light source A and a charcoal B. In both FIG. 1 and FIG. 2, the light source A, the charcoal B, and the filter E have a structure that allows periodic inspection, maintenance, and replacement.

[0009]

The present invention is constituted as described above, and this effect will be described below.

[0010] Since air purification is performed by natural convection composed of charcoal and a static main component of a light source, there is no noise or vibration, and it is most suitable for rooms requiring quietness, such as hospitals, libraries, restaurants, and bedrooms.

A simple design and a simple structure make it easy to handle. In particular, since there is no electric equipment, the running cost is low, and there is no failure or abnormality that is likely to occur in the case of this drive.

Since a light source (for AC 100 V) is used, it can also be used as a nighttime or dark indoor lighting device.
