Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air purifier which sucks in and purifies dirty air in a room and circulates it again in the room.

[0002]

2. Description of the Related Art In recent years, an air purifier for purifying polluted air in a room has become widespread for an indoor environment, and accordingly, a demand for an air purifier having a high purification efficiency is increasing. A conventional air purifier of this type will be described with reference to FIGS.

As shown in the figure, a main body 21 of the air purifier is formed by a front main body 23 having an intake port 22 and a rear main body 25 having an exhaust port 24, and a suction port 26 is provided inside the main body 21. A main body partition wall 27 is provided, an electric blower 28 is provided in the rear main body 25, and a vortex chamber 29 communicating with the exhaust port 24 is formed.

In the front main body 23, there is a filter 31 having an activated carbon filter and a charging filter, which are arranged so that a portion opposite to the suction port 26 is curved so as to project forward by a rib 30 provided on the main body partition wall 27. I support you. Further, a changeover switch section 32 having a control circuit section therein is provided on the upper front surface of the front body 23.

To explain the operation in the above configuration, when the electric blower 28 is driven by the changeover switch section 32, the polluted air is sucked in through the intake port 22, the sucked air is purified through the filter 31, and the intake port 26. Further, it enters the swirl chamber 29, is sent from the swirl chamber 29 to the exhaust port 24, and the purified air is exhausted from the exhaust port 24.

[0006]

In such a conventional structure, as shown in FIG. 7, a filter 31 which is a combination of an activated carbon filter and a charging filter has a suction port 26 portion which is arranged so as to project and curve forward. Therefore, there is no gap between the filter 31 and the main body partition wall 27 in the portion other than the facing portion of the suction port 26, there is no passage for the suction air flow to the suction port 26, and the action of cleaning the dirty air flow is the suction. This occurs not only in the center of the filter 31 at the portion facing the mouth 26, but also because the number of air flow passages is small, the amount of sucked air decreases.

The present invention solves the above-mentioned problems, and secures a passage for the suction air flow to the suction port between the filter and the partition wall of the main body, and makes it possible to clean the entire area of the filter and prevent a decrease in the air volume. The purpose is to provide an air purifier.

[0008]

In order to achieve the above object, an air purifier of the present invention has a main body of an air purifier having an intake port and an exhaust port formed by a front main body and a rear main body,
A main body partition wall having a suction port provided so as to partition the front main body side and the rear main body side in this main body, and an electric blower provided in the main body, and a vortex formed to communicate with the suction port and the exhaust port. A chamber and a filter provided in a filter frame formed in the main body partition wall by bending a central portion of the front main body facing the suction port forward, and a filter frame in the vicinity of the filter end portion Inside, the main body partition wall is provided with a recess so that a recessed air passage is formed outside the swirl chamber.

[0009]

In the air purifier of the present invention having the above-described structure, the portion other than the swirl chamber is recessed rearward in the filter frame. Therefore, in this recessed portion, the filter and the main body other than the suction port are formed. By ensuring the air passage for the suction air flow to the suction port between the partition wall and the air passage in the entire area of the filter, it is possible to clean the air in the entire area of the filter and prevent a decrease in the air volume.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.
Will be described with reference to.

As shown in the figure, the main body 1 of the air purifier comprises a front main body 3 having an intake port 2 and a rear main body 5 having an exhaust port 4.
The front body 3 side and the rear body 5 are formed inside the body 1.
A main body partition wall 7 having a suction port 6 that divides the side is provided,
An electric blower 8 is provided in the rear body 5, and the suction port 6
A swirl chamber 9 communicating with the exhaust port 4 is formed.

In the front main body 3, a rib 10 and a filter frame 11 provided on the main body partition wall 7 are combined with an activated carbon filter and a charging filter arranged so that the central portion of the suction port 6 facing forward is curved so as to project forward. The filter 12 supported by the filter 12 is supported and is recessed outside the vortex chamber 9 in the filter frame 11 near the end of the filter 12, and the filter 1 is provided between the filter 12 and the main body partition wall 7.
The main body partition wall 7 is provided with a recess 13 that forms an air passage for the air passing through 2.

Further, a changeover switch portion 14 having a control circuit portion therein is provided on the upper front surface of the front body 3.

The operation of the above structure will be described. When the changeover switch section 14 drives the electric blower 8,
The polluted air is sucked in through the intake port 2, the sucked air is purified through the filter 12, enters the swirl chamber 9 through the suction port 6, is sent from the swirl chamber 9 to the exhaust port 4, and is exhausted through the exhaust port 4. Purified air is exhausted.

Since the portion other than the vortex chamber 9 is recessed rearward in the filter frame 11, the recess 13 sucks the portion between the filter 12 and the main body partition wall 7 other than the suction port 6 portion. By ensuring the passage of the intake air flow to the mouth 6, the passage is ensured in the entire area of the filter 12, the intake air flow flows to the intake opening 6 without being obstructed, and the cleaning action is performed in the entire area of the filter 12. The reduction of the air volume is also prevented.

[0016]

As is apparent from the above embodiments, according to the present invention, the portion other than the swirl chamber is recessed rearward in the filter frame, so that the portion other than the suction port portion is formed in this portion. Since a passage for the suctioned air flow to the suction port between the filter and the bulkhead of the main body can be secured, the passage is secured in the entire area of the filter, and the entire area of the filter can be cleaned and the air volume can be prevented from decreasing. Can be provided.
