Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to indoor air by collecting dust contained in air and removing smoke and odor of cigarettes by utilizing anion generation by corona discharge. The present invention relates to an electrostatic air cleaning device for purifying air.

[0002]

2. Description of the Related Art In recent years, various air purifiers have been offered to the market in pursuit of comfort in response to air pollution or odors and dusts generated in living spaces. Among the dust collection methods that use corona discharge to collect charged dust on the surface of the dust-collecting paper, the auxiliary dust-collecting paper used for the dust-collecting method is made hollow by making the dust-collecting electrode holder hollow. They are stored and stored, and only the necessary amount is taken out when used. For example, there is JP-A-8-10646.

[0003]

However, in the above-described apparatus, the roll-shaped portion 17a for assisting the dust-collecting paper 17 can be freely taken in and out of the space 18, and the upper portion of the space 18 is always open and communicates with the outside air. It is in a state where it has been done.

Therefore, when the air cleaner is used in this state, the negatively charged dust is collected on the surface of the dust collecting paper 17, but a part of the dust also adheres to the upper end surface of the roll-shaped portion 17a. When the dust collecting paper 17 is contaminated and replaced, there is a disadvantage that the auxiliary dust collecting paper is also contaminated.

[0005]

In order to solve the above-mentioned problems, the present invention has the following arrangement. It is. That is, an ionization electrode, a dust collection electrode provided opposite to the ionization electrode, a dust collection electrode holder having a hollow cylindrical shape around which the dust collection electrode is wound and having an upper opening, and a dust collection electrode holding member. A main body cover which is covered with a dust paper which is provided so as to be freely attached while covering an annular dust collection electrode wound around the body,
Further, the present invention is characterized in that an auxiliary dust-collecting paper is accommodated in a hollow portion from an upper opening of the dust-collecting electrode holder, and the upper opening is constituted by an opening / closing body provided to be freely opened and closed.

Next, the opening / closing body is formed of a disc-shaped body provided on the inner surface of the ceiling plate of the main body cover or the inner surface of the ceiling plate, and when the main body cover is applied, the opening of the hollow portion is closed. .

Further, the opening / closing body is formed of a disk-shaped lid provided so as to close the upper opening of the dust collecting electrode holder. It is closed by closing.

[0008]

According to the above construction, the dust collecting electrode is covered by the dust collecting electrode holder having a hollow cylindrical shape with the dust collecting electrode wound around the outer periphery and storing the auxiliary dust collecting paper through the upper opening. Further, it is assumed that the apparatus is used with the main body case applied and the upper opening closed. Dust charged by negative ions adheres only to the surface of the dust collection paper.

Further, the upper opening is closed by applying the main body cover with the inner surface of the ceiling plate of the main body cover or a disk-shaped body provided on the inner surface of the ceiling plate.

Next, the same operation as described above is performed by applying a separate lid to the upper opening.

[0011]

An embodiment of the present invention will be described with reference to the drawings.
In the figure, an electrostatic air purifying apparatus includes a base 1 having a circular trapezoidal shape, a dust collecting electrode holder 2 located on the base, having a hollow cylindrical shape and opening upward, Two upper and lower annular dust collecting electrodes 3 and 3, a dust collecting paper 4 provided so as to cover these dust collecting electrodes from the outer periphery and to be freely attached thereto, and An ionizing electrode 5 positioned at an interval from the dust-collecting paper, and further from above so as to surround the dust-collecting electrode holder 2 and the dust-collecting electrodes 3, 3, dust-collecting paper 4, and the ionizing electrode 5 attached thereto. It comprises a body cover 6 to be mounted.

The front base 1 incorporates circuit components for generating a low voltage, for example, -7 KV and a high voltage of +7 KV, which are connected to a power supply. Therefore, a low voltage is connected to the ionization electrode 5 and a high voltage is connected to the two dust collecting electrodes 3 and 3, and these two dust collecting electrodes can apply different voltages vertically.

The body cover 6 has a cylindrical shape with a bottom.
The body part penetrates in and out to form a large number of slit-shaped grooves 7 in the lateral direction, so that the outside air enters the inside, is charged by the ionization electrode 5, and is sucked by the dust collection electrodes 3, 3. Then, dust in the air is collected on the dust collecting paper 4. The cover 6 is covered with the bottom opening as the ceiling plate 8 with the lower opening facing downward, and is locked and fixed to the base 1 using the engaging body 9 provided on the periphery of the opening. When the dust collecting paper 4 is to be replaced, the engagement body 9 is disengaged and detached from the base.

Next, a configuration which is a main part of the present invention will be described. The dust collecting electrode holder 2 is configured such that an auxiliary dust collecting paper 11 is inserted through an upper opening 10 so that the dust collecting electrode holder 2 can be housed in a hollow portion, and the upper opening 10 is provided on an inner surface of a ceiling plate 8 of the main body cover 6. To close. Alternatively, an opening / closing body 13 having a surrounding annular skirt portion 12 is provided by projecting the ceiling plate 8 downward, and this opening / closing body is closed around the upper opening 10.

Further, the opening / closing body 13 may be formed as a single plate-shaped lid body separately from the main body cover 6, and may be pivotally supported on the peripheral edge of the upper opening to be freely openable / closable. It may be provided freely.

The ionization electrode 5 may be provided with a needle-like body on the base as exemplified in the prior art. As shown in the embodiment of the present invention, an annular ring is provided on the back surface of the ceiling plate 8 of the main body cover 6. A suspension body 14, a plurality of suspension legs 15, and an ionization electrode 5 provided at the lower end of the suspension body are provided. The ionization electrode 5 is formed as an annular plate and provided with a number of pointed portions 16, which are two dust collection electrodes. It arranges so that it may be located in the middle of 3 and 3.

[0017]

As described above, the present invention relates to an opening / closing body in which an auxiliary dust collecting paper is accommodated in a hollow part from an upper opening part of a dust collecting electrode holder, and the upper opening part is provided so as to be freely opened and closed. As a result, the auxiliary dust collecting paper is prevented from being contaminated during use. That is, it prevents the charged dust from adhering to the upwardly facing portion when storing the auxiliary dust collecting paper using a paper towel or toilet paper.

Further, according to the second aspect, since the opening / closing body uses the inner surface of the ceiling plate of the main body cover as it is or is constituted by a disc-shaped body provided on the inner surface of the ceiling plate, the upper opening is formed by the main body cover. Since it is closed at the time of wearing, it does not require any trouble and achieves the intended purpose.

By forming the opening and closing body separately by a disc-shaped lid, the closing operation can be performed accurately.
