Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an air purifier that sucks in indoor dirty air, purifies it, and circulates it indoors again.

BACKGROUND ART Conventionally, this type of air purifier is shown in FIG. 5, for example.
The structure was as shown in FIGS. 6, 7, and 8. That is, the main device for cleaning the air is housed in a box consisting of a front box 1 and a rear box 2, and a front grill 3 with a number of air intake ports 3a is provided on the front. An operation switch section 4, an exhaust louver 5, and a removable filter 6 are arranged at the . 7 is a prefilter that collects relatively coarse particles in the air; 8 is a high-voltage discharge wire; 9 is a cover for the discharge wire; 10 is a counter electrode of the discharge wire 8; A counter electrode plate is formed by bending both side edges to form a bent flange 10b having a U-shaped cross section. The discharge wire 8 and the counter electrode 10 constitute an ionization device, and the fine particles not collected by the prefilter 7 are ionized and are electrically adsorbed by the filter 6, which constitutes a negative electrode. . 11 is a partition wall that forms a vortex chamber 12 together with the rear box body 2;
The vortex chamber 12 has a suction port 11a opened in the partition wall 11.
The fan 1 is driven by a drive motor 13 fixed by a plurality of arms 11b extending toward the center of the opening of the fan 1.
4 is placed.

Reference numeral 15 denotes a hanger used for attaching the air purifier to the wall of the room; it is fastened to the wall of the room with screws, and the hook part 16 formed on the hanger 15 is hooked to the hook part 17 formed on the rear box body. It is attached to the wall.

18 is rubber for support.

Problems that the invention aims to solve However, with this type of configuration, when the air purifier is used by hanging it on a wall indoors as shown in Figure 7, or when the air purifier is used by hanging it on a desk indoors as shown in Figure 6. This is true in both cases, such as when placed on top or on a shelf, but the intake port 3a on the front of the main unit sucks in dirty air and clean air is exhausted from the exhaust louver 5. Since the intake and exhaust air flow is flat and not three-dimensional, the circulation of air in the room is not sufficient, and it takes time to thoroughly clean the dirty air in the room.

In addition, when used on a wall, the main unit is further turned upside down and the exhaust louver 5 is installed facing downward, so cigarette smoke, etc. that generally rises upwards from the bottom of the room will be removed. , intake port 3
It was blown away by the exhaust air before being sucked into a, which had the opposite effect.

Therefore, the present invention provides an intake port on the left and right sides of the main unit, and an exhaust port on the top and front surfaces of the main body, thereby allowing the intake and exhaust air to flow three-dimensionally and efficiently circulate indoor air. is the primary objective.

The second purpose is to provide an inclined plate inside the exhaust port to prevent vortices and turbulence in the exhaust flow and to smoothly exhaust the air both upward and forward.

Means for Solving the Problems In order to achieve the first object, the present invention has four sides of the substantially square main body front section inclined toward the center of the front surface, and an air intake provided on the left and right inclined surfaces. The opening is provided with an attachment/detachment part for the dust collector on the lower inclined surface, and an exhaust port is provided on a part of the upper inclined surface, and the exhaust port is expanded to a part of the front wall.

Next, in order to achieve the second objective, an inclined plate is provided inside the exhaust port and on the inner wall of the rear part of the main body, and is inclined toward the exhaust port.

Function The air purifier of the present invention has the above-mentioned configuration, sucks in dirty air through the intake ports provided on the left and right inclined surfaces of the main body, and collects dust through the exhaust ports connected to the upper inclined surface and a part of the front wall. It exhausts clean airflow and performs the intake and exhaust airflow three-dimensionally to efficiently circulate indoor airflow, and the main unit can be mounted upside down even when used on a wall. This device sucks in dust such as cigarette smoke from both the left and right sides without blowing it away by exhaust air, which exhausts the air toward the front and rises from the bottom to the top of the room.

In addition, by providing an inclined plate on the inner wall of the rear part of the main unit inside the exhaust port, which is inclined toward the exhaust port, this problem occurs because the path of the exhaust flow is bent forward at a right angle deep inside the exhaust port. This prevents the occurrence of swirls and turbulence in the exhaust flow at the rear corners of the main body, and smoothes the flow of the exhaust flow. The exhaust flow discharged from inside the main body hits the inclined plate to tilt the course and smoothly change the flow toward the exhaust port.

Embodiments Hereinafter, embodiments will be described based on the accompanying drawings. In Figures 1, 2, 3, and 4,
The main device for purifying the air is housed in a substantially rectangular box made up of a front body part 19, a rear body part 20, and a body support plate 21. Each of the four sides of the front part of the main body is sloped toward the center of the front surface, with an intake port 22 on the left and right slopes, a removable part for the filter 23 on the lower slope, and an exhaust port on a part of the upper slope. 24 is formed extending to a part of the front wall.

Operation switch section 25 and display panel 2 on the front upper part
6. A UV sensor 27 is provided. 28 is a body lid, and 29 is a mounting base. A louver device 30 is disposed inside the exhaust port 24 and includes a support plate 31, a blade A 32, a blade B 33, a connecting plate 34, and an operating knob 35. Numeral 36 is a hole formed in a part of the exhaust port 24 through which the operating knob 35 can be inserted and operated from the outside. The louver device 30 connects ribs 37 and lower walls 38 formed on both sides of the support plate 31 to the front part 1 of the main body.
The main body support plate 21 and ribs 21a formed on the main body support plate 21 sandwich and fix the main body support plate 21 from the rear. 40 is screwed to the wall with a wall hanging bracket. 41 is a tilted plate located at the back of the exhaust port 24. When using the air purifier by placing it on the floor, table, shelf, etc., use the mounting base 29 to direct the forward exhaust upward. If you want to change it, use the exhaust port 24.
It is also possible to change the orientation of the internal blades A32 and B33 by operating the operating knob 35.

When using it by hanging it on a wall, remove the mounting base 29, attach the body cover 28 to the exhaust port 24 on the sloped surface of the upper surface, attach it to the wall hanging bracket 40, and then operate the operation knob 35 downward to move the body cover 28 upward and forward. The body cover 28 blocks the upward (towards the ceiling) exhaust to prevent the ceiling surface from being contaminated by the exhaust flow.

Dirty air is sucked in through the intake ports 22 provided on the left and right slopes of the main body, and after being cleaned, the clean air is exhausted through the exhaust ports 24 connected to the upper slope and a part of the front wall. The airflow is carried out three-dimensionally, and the airflow in the room is circulated three-dimensionally from side to side, front and back, and up and down, making it possible to quickly clean the indoor air.

In addition, when used on a wall, the exhaust is directed forward and the dust such as cigarette smoke that has drifted upwards from the bottom of the room is not blown away by the exhaust, and the same three-dimensional effect is achieved. This allows indoor air to be circulated efficiently.

In addition, the inclined plate 41 screwed inside the exhaust port 24 and to the rear part 20 of the main body directs the exhaust flow generated at the corner of the rear main body 20 inside the exhaust port 24 toward the front. This prevents the occurrence of eddy currents and turbulent flows caused by colliding with the upper wall and changing the course, and allows the exhaust flow to flow smoothly in two directions: upward and forward.

The exhaust flow discharged from inside the main body collides with the wall surface of the inclined plate 41 that is inclined toward the exhaust port 24, changes its path to the exhaust port 24, and flows smoothly. Therefore, there is no generation of eddy currents or turbulent flows, and the resulting noise such as whirring noise of the air flow is also prevented.

Effects of the invention As described above, according to the invention, the intake and exhaust air flows three-dimensionally, the indoor air is circulated efficiently, and the indoor air can be purified quickly. be.

Furthermore, by attaching an inclined plate to the inner wall of the rear part of the main body inside the exhaust port, it is possible to prevent the occurrence of vortices and turbulence in the exhaust flow and to make the exhaust flow flow smoothly.
