Abstract

PURPOSE:To prevent an electric shock and to facilitate assembly, cleaning and maintenance by forming an end plate for forming a surface to be exposed to the outside of a filter case to a shape to cover the surface on a discharge port side and using the end plate as a pivotal support for a louver. CONSTITUTION:The end plate 33 forming the surface to be exposed to the outside of the filter case 29 is formed to the shape to cover substantially the front face of the discharge port 23 side surface 34 of a body 21 and further a discharge hole 35 of the same shape communicating with the discharge port 23 is formed. Then, the exposing of a disconnected discharge wire 26 to the outside of the body 21 from the insertion port is prevented by the end plate 33, by which the electric shock is prevented. The grating-shaped louver 36 for varying the discharge direction of the port 23 is so constituted that the louver can be freely turned between the body 21 and the end plate 33. The louver 36 is, therefore, assemblable and removable simultaneously with the attachment and detachment of the filter case 29, by which the ease of assembling, cleaning and maintaining the cleaner is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an air cleaner that collects dust by applying a high voltage between a discharge wire and a counter electrode.

2. Description of the Related Art The general structure of a conventional air purifier of this type will be described with reference to FIGS. 6 to 14.

Air purifiers can be roughly divided into two types: one in which the main body 1 is mounted on the wall as shown in Fig. 6, and the other in which the main body 1 is placed on the floor as shown in Fig. 7. In both types, the intake port 2 is Located at the front. When the main body 1 is mounted on a wall, an exhaust port 3 is provided on the bottom surface, and when the main body 1 is mounted on a wall, an exhaust port 3 is provided on the top surface. As shown in FIG. 8, in both types, inside the intake port 2 and in the ventilation path 4 connecting the intake port 2 and the exhaust port 3, there is an ion generator with a counter electrode 5 and a discharge wire 6 facing each other. A section 7 is provided. Furthermore, a flat filter case 9 holding a dust collection filter 8 that adsorbs charged dust is disposed downstream of the ion generating section 7 in the ventilation path 4.
This filter case 9 is detachably attached via an insertion opening 10 formed in the main body 1 by inserting and removing it. As shown in FIG.
0, the dust flowing in from the intake port 2 is charged. By this, an air flow is generated along the ventilation path 4 from the intake port 2 to the exhaust port 3 by the electric scooping and pulling 12, so that the charged dust described in 1) and 1) is transferred to the air flow. While I was riding, I took a look at Tojo Filter 8. Also, Kin;:
As shown in FIGS. 11 and 13, the Fa 6 is stretched between the discharge wire supports 14 via the beams 13. The exhaust port 3 is provided with a looper 15 having a groove J' so as to change the direction of the exhaust, and the rotating shaft 16 of the looper 15 is connected to the protrusion of the water body back plate 17, as shown in FIG. λ4 to this shaft support 18.
(Turn it between L6 and the groove 19 provided in the main body 1)
It is freely supported.

The problem that the investigation is trying to solve is this J, um, with conventional air purifiers, yJ- lives and accidents, etc. When the filter case hangs down, the height between the filter case and the insertion opening 10 is 1 as shown in Figure 9.
:11 There is a risk of exposure to the outside of the main body 1. In particular, when the filter case 9 is taken in and taken out as shown in FIG. 10, it is simply exposed to the outside.

This is how it was exposed. There is a problem in that if the name used accidentally touches the makichuan 6, it may cause unpleasant sensations such as electric shock.

In addition, when using the main body 1 on the floor, the insertion slot 10
Since the filter case 9 is facing upward, the filter case 9 is placed on the surface of the water body 1.
The end surface of the sheet was easy to protrude, and the appearance did not come off.

As a problem in assembly, as shown in FIG. 9, the rotating shaft 16 of the looper 15 is supported by the shaft support 18 protruding from the daikon radish 17 and inserted into the main body 1 at the same time as the main body is assembled, making the assembly complicated. Moreover, in order to clean the looper 15 due to air pollution, etc., it was necessary to disassemble the main body.

The present invention solves the above-mentioned problems, and has a highly safe V4 structure that prevents the discharge wire from being exposed to the outside of the main body even if the discharge wire is disconnected. The air purifier has a clean appearance with no visible V-eyes, etc., and is easy to set up during production and easy to maintain during use. The purpose is to provide

Means for Solving f+W 'IL L:, j In order to solve the above problem, the present invention provides an ion generating section in which a ion gland and a counter electrode are arranged opposite to each other in the air passage connecting the intake port and the exhaust port. A filter case is provided in which the dust collecting filter for adsorbing charged dust is completely held on the -F flow side of the ion generating part in the ventilation passage, and a filter case is provided in which the filter case is detachably attached to the main body. If the end plate that forms the surface exposed to the outside of the filter case is formed in a shape that covers the exhaust port side of the main body, then in 5, this end plate has a communication Δ with the exhaust port.
-1^ air holes are formed, and the exhaust port is provided with a looper for varying the exhaust direction, which is rotatably supported between the main body and the end plate.

Effect When the above configuration is adopted, the end plate forming the surface exposed to the outside of the filter case covers the front surface of the insertion port 1 for removing the filter case. This prevents the insertion port from being exposed to the outside of the main body, and the appearance is also cleaner because the insertion slot is not visible. Furthermore, the looper can be easily assembled when the filter case is attached after the main body is assembled, and maintenance such as cleaning of the looper can also be easily performed by removing the filter case.

EXAMPLE Hereinafter, an example of the present invention will be described based on FIGS. 1 to 5.

The air purifier fII is roughly divided into main body 2 as shown in Figure 4.
1 mounted on a wall, and the main body 21 as shown in Figure 5.
There is a floor-standing type and a floor-standing type, and both types have an intake port 22.
is provided at the front. In a case where the main body 21 is mounted on a wall, an exhaust port 23 is provided on the bottom side, and in a case where the main body 21 is placed on the floor (in a case where the main body 21 is mounted on a floor), an exhaust port 23 is provided on the top side. In both types, the intake port 22
An ion generating section 27 with a counter electrode 25 and a discharge wire 26 facing each other is provided inside the air passage 2□1 connecting the intake port 22 and the exhaust port 23. Furthermore, a flat filter case 29 holding a dust collection filter 28 that adsorbs charged dust is disposed downstream of the ion generating section 27 in the ventilation path 24, and this filter case 29 can be inserted into and removed from the main body 21. It is detachably attached via the formed insertion port 30. Then, a lightning strike 4 is applied to the counter electrode 25.
! ; A high voltage is applied to 126 by the high voltage generating unit 31 to charge the dust flowing in from the intake port 22. An electric blower 32 is provided on the downstream side of the dust filter 28 in the ventilation path 24, thereby generating an air flow from the intake port 22 to the exhaust port 23. Here, the end plate 33 that forms the surface exposed to the outside of the filter case 29 is formed in a shape that covers almost the front surface of the surface 3A of the main body 21 on the exhaust port 23 side, and furthermore, the end plate 33 forms the surface exposed to the outside of the filter case 29. A shaped exhaust hole 35 is formed. A lattice-shaped looper 36 for variable exhaust direction provided at the exhaust port 23 is connected to the main body 21.
It is rotatably supported between the end plate 33 and the end plate 33. That is, a U-shaped fitting groove 37 whose outer end surface and inner surface are open is formed on a pair of opposing side walls of the west wall forming the exhaust port 23, and an exhaust hole is formed on the back surface of the end plate 33. A protrusion 38 is formed from the edge of 35, which can be inserted into and removed from the fitting groove 37 and has a concave tip. The rotating shaft 39 of the looper 36 can be fitted into and removed from the fitting groove 37, and the concave surface of the tip of the projection 38 can be brought into contact with the rotating shaft 39.

The operation of the above configuration will be explained. Discharge 1Pi1
Even if the wire 26 is broken in the middle, the gap between the filter case 29 and the insertion port 30 is held down and covered by the end plate 33, as shown in FIG. do not. Additionally, as shown in Figures 4 and 5,
The entire surface of the surface 34 on the side of the exhaust port 23 except for the exhaust hole 35 is uniformly covered with the end plate 33 of the filter case 29, giving it a clean and easy-to-see appearance. and looper 36
As shown in FIG. 2, the assembly is performed by aligning and inserting the rotary shaft 39 of the looper 36 into the fitting groove 37 on the main body 21 side, and then pushing the filter case 29 into the main body 21 to remove the MW.
By simply doing this, the rotating shaft 39 can be pivotally supported between the main body 21 by the protrusion 38, and assembly can be easily performed without the need for tools. Furthermore, crushing of the looper 36 can be done extremely easily since it can be disassembled by the reverse operation to the above, and after cleaning, it can be assembled in the same manner as described above.

Effect of Light According to the present invention, the end plate that forms the surface exposed to the outside of the filter case is shaped to cover the surface on the exhaust port side, so that the disconnected discharge wire will not be exposed to the outside of the main body from the insertion port. This end plate prevents electric shock due to disconnection, and also provides a clean appearance. In addition, since the end plate is also used as a shaft support for the looper, the looper can be assembled or taken out at the same time as the filter case is attached or removed, making it possible to improve ease of assembly and cleaning and maintenance.
