Abstract

PURPOSE:To repeatedly use a filter having normal removing capacity and to efficiently purify the air by providing plural prefilters to a first unit and furnishing an elastic body on the delivery side of the unit or to the suction side of a filter holder. CONSTITUTION:A filter unit 6 is provided with plural prefilters 9, an elastic body 12 is furnished on the delivery 7 side of the unit 6 or on the suction 2 side of a filter holder 10, and the frequency of exchanges and the fact that the filter is the last one are indicated on the surface of the prefilter 9 to be released and exchanged. Consequently, only the prefilter on the suction side which has been quickly clogged is released, and the filter which has not been sufficiently used and having normal removing capacity is repeatedly used. Besides, the filter unit is firmly attached to the filter holder to efficiently purify the air. Further, since the frequency of exchanges, etc., are indicated, the exchanging time is confirmed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air cleaner, and more particularly to the structure of a filter unit.

[0002]

2. Description of the Related Art In a conventional air purifier filter, a filter unit in which dust collecting and deodorizing functions are combined in one box in multiple layers to form a unit is detached through a filter exchange port provided in the main body. It is free.

[0003]

In the conventional filter for the air cleaner, the filter unit is installed in an inverted manner when the filter unit is replaced, and a gap is easily generated due to the displacement between the filter unit and the filter support base. It is causing the leak. In addition, since the filter unit is small, the pre-filter surface, which attaches relatively large dust, can be clogged in a short time, and even if other functions such as the deodorizing filter are normal, the filter unit must be replaced with another one, which is a resource saving problem. Is.

[0004]

In order to solve the above-mentioned problems, a plurality of pre-filters of detachable filter units are arranged on the main body so that they can be separated. As another means, an elastic body is provided on the discharge port side of the filter unit. As still another means, an elastic body is provided on the suction port side of the filter support base. Further, as another means, a number or the like is displayed so that the number of times of peeling on the prefilter to be peeled off and the final number can be understood.

[0005]

By removing the pre-filter by using the above-mentioned technical means, it is possible to repeatedly use the other filter having the removing ability, which is provided in the filter unit, and the pre-filter which is peeled and replaced. It is possible to know the replacement time by displaying the number of peeling on the surface and the last number. Further, by providing an elastic body on the outlet side of the filter unit or an elastic body on the suction side of the support base of the filter, the gap between the filter unit and the filter support base is eliminated, and the filter unit can be more reliably inserted through the filter unit. Clean air is obtained.

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is a sectional view of an air purifier with an artificial ornamental plant for floor installation, which is an embodiment of the present invention. The main body upper part 1a having the artificial ornamental plant sucks in the indoor dust and the like at the suction port 2 serving as the indoor air intake port, while the main body lower part 1b sucks air from the upper suction port 2. Having a blower 5 composed of a fan 3 and a motor 4 and discharging air from a discharge port 7 through a filter unit 6 capable of exchanging the air sucked in the blower 5 for cleaning while circulating the indoor air. Is.
FIG. 2 is a development view of the filter unit 6 shown in FIG. A filter unit 6 for an air purifier that can be taken in and out from a filter exchange port 8 in the inside 1b of the main body shown in FIG.
In particular, the filter unit 6 has a long life because the filters 11a, 11b, and 11c having other normal removal capabilities can be repeatedly used by peeling off only the suction port side pre-filter 9 that is quickly clogged. Also, when the filter unit 6 is installed on the filter support base 10,
Due to the deformation or inclination of the filter unit 6 or the filter support base 10, wind enters through the gap between the filter unit 6 and the filter support base 11 to reduce the collection efficiency, so that the elastic body 12 is provided on the discharge port side of the filter unit 6. When the filter unit 6 is installed and the filter unit 6 is installed, the adhesion between the filter unit 6 and the filter support 10 can be improved, and the collection efficiency can be improved. Further, by providing the elastic body 12 on the discharge port side of the filter unit 6, the suction port (upper side of the main body) and the discharge port (lower side of the main unit) of the filter unit 6 are made clear, and the filter unit 6 is reversed. It becomes possible to prevent wearing. FIG. 3 is a diagram in which an elastic body is provided on the suction port side of the filter support base. The filter unit 15 can be replaced by sliding the filter exchange port cover 16 on the back side of the lower part 13 of the main body left and right. Elastic body 14 on the suction side of 15
The filter unit 17 installed on the filter support base 15 provided with can be replaced by pulling it out to the back side of the main body. At the time of this replacement, the adhesion between the filter unit 17 and the filter support base 15 when the filter unit 17 is installed can be improved, and the collection efficiency can be improved. FIG. 4 shows the number of times of use and the last one on the surface of the pre-filter 18 to be peeled and replaced by providing a plurality of pre-filters, and the replacement time can be known.

[0008]

EFFECTS OF THE INVENTION According to the present invention, the filter replacement can improve the conventional method of replacing the filter unit, and the removal capacity which is not sufficiently used for peeling off only the prefilter on the suction port side where clogging is fast. It is possible to repeatedly use a filter that is normal. Further, by providing the elastic body on the discharge port side of the filter unit, the filter unit is prevented from being installed in the opposite manner, and the gap between the filter unit and the filter support base is eliminated, so that an efficient air cleaning action can be obtained. Further, it is possible to know the replacement time from the number of times of use and the last one on the surface of the pre-filter on the suction port side of the filter unit.
