Description

[Detailed Description of the Invention] The present invention is a wall-mounted device that also serves as wall decoration and has an air purifying function, without making people feel that the air purifier is a separate item from the wall. It belongs to the technology of movable partitions that make it feel like it is integrated with the wall, and the technology of electrostatic precipitators that make it possible to reduce the width and noise of this device.

Electrostatic precipitator technology or equipment consists of installing thin metal wires in an insulated state inside a flat plate or duct, and applying a high potential difference to these wires to cause a corona discharge, which collects positive ions into suspended particles. It is charged to collect fine particles on a flat plate with a negative electrode.

However, conventional electrostatic precipitators require forced ventilation in order to introduce floating micron-sized particles into the electric field within the device, and a ventilation motor is usually provided as a means for this purpose. For this reason, the vibrations and noise generated when the motor is driven have been viewed as a problem, as they impair the quiet indoor environment.

In addition, since an electrostatic precipitator incorporates many electrode plates, the motor, etc.
It has to be large, and even those that are called portable for home use are about 40 to 50 cm square, and are often placed in a corner of a room or used as wall hangings or insets. However, all of them constricted the indoor environment, were difficult to install, or were considered aesthetically unsightly, and most importantly, the installation itself was complicated.

In addition, with electric dust collectors used in large central air conditioning systems, noise is rarely a problem, but since it is forced ventilation, you will constantly feel the movement of the wind in the room, and if it is only used in one room. There was a lot of frustration that running costs would be high because it would not be possible to manage this.

Furthermore, even though forced ventilation is used in conventional indoor electrostatic precipitators, suspended particles can only be effectively moved within an area relatively close to the equipment, making it unnecessary to use drafts. If you try to make it stronger, it will not only reduce the dust collection effect, but also cause discomfort and increase noise, so it is recommended to install multiple devices facing each other in order to achieve the effect in all rooms. However, due to problems such as making the room smaller and noise, it was rarely implemented.

However, electrostatic precipitators are considered to be the most effective method for collecting airborne particles.
Therefore, in order to solve the above problems, the applicant made the hollow part of the movable partition wall panel (hereinafter referred to as the panel) as a duct (ventilation pipe), and We have developed a wall-mounted air purifying device (International Application No. JP84/00246) that uses a slim (slim) wind-generating electrostatic precipitator that can be housed in a refrigerator.

The use of the above-mentioned invention in which an electrostatic precipitator is incorporated into a panel when constructing a partition or for repairing the panel brings about unprecedented effects and has been highly evaluated in the market as an epoch-making product.

The present invention is devised to cover the surface of the panel, rather than incorporating an air-blowing electrostatic precipitator or the like into the panel itself. Although the invention satisfies most of the needs as just mentioned, there is a tendency for existing panels (rooms) to not be actively adopted unless the room is being redecorated. can be seen. In addition, in the direction of permanent walls that do not have hollow parts such as concrete walls,
Even if there is a demand for air purification, there are cases where it is not possible to use the above-mentioned invention, and the existing rooms have a sense of familiarity that has been created over the years, and while it is welcomed, it may also create a sense of discomfort. The present invention was created in response to these new demands.

For this reason, the present invention uses a flat plate with a shape, color, or pattern that is the same as or matches (similar to) the existing wall, and the width is the width of one panel or the required width, and the height is adjusted. The top plate is set at a height approximately from the floor to the ceiling, the air inlets and outlets are opened in the top plate, and an electrical insulating device is attached to this with an electric dust collector as thin as possible inside. The ventilation duct is attached to a fitting frame created by a pair of vertically long wall-fixing frame members fixed to the existing wall and a pair of vertically long equipment connecting columns connected to these.

In order to describe the present invention in more detail, it will be explained below with reference to the accompanying drawings.

FIG. 1 shows an apparatus top plate 1, which is a flat plate made of a hard material, although it may be made of wood, metal, resin, or the like.
The flat plate should have the same shape, color, and pattern as the existing wall or panel, or should match it. A connecting pieces 5, 5 are provided vertically at the left and right ends, and an air intake port 2 is formed on the surface to form an air intake part. The inlet/outlet part of the wind electric precipitator 3 is opened, and the air outlet 4 is opened below it to form the apparatus top plate 1.

In the embodiment, a flat metal plate is used, and the shape of the A connecting piece 5 is made into a vertically elongated shape with a U-shaped cross section by bending the left and right ends inward and outward at right angles.

The air-blowing electrostatic precipitator 3 is a slim type that is mostly housed inside the duct tube 6, but even if it slightly protrudes from the surface of the device top plate 1, the air intake port cover 9
I will not expose myself by relying on it.

The air inlet cover 9 and the air outlet cover 10 are made of flat plates (metal plates in this example) that are made of the same material, color, and pattern as the device top plate 1, and have openings for air inlet and outlet to prevent fingers from entering. A protection net 12 is attached to it.

Upper frame material 7 and lower frame material 8 (metal frame material in the example)
are attached to the upper, lower and lower ends of the device top plate 1, and correspond to the upper and lower portions of the device frame, serving as reinforcement.

FIG. 4 shows a wall fixing frame material 14 and a device connecting column 15 that form a fitting frame for fitting and fixing the device main body 11 on the front side of an existing wall or panel 13.
It shows. Both members are vertically elongated members having the same height as the device main body 11, and are made of a hard material.

The wall fixing frame member 14 has a fixing means for fixing to the wall or panel 13 surface, and a coupling means for coupling with the device coupling column 15 and holding it perpendicular to the wall or panel 13. In the embodiment, it is an L-shaped angle member made of metal, with a plurality of screw holes 16, 16 drilled in the upper and lower sides of two perpendicular surfaces, one surface serving as the fixing means, and the other surface serving as the fixing means. It is also used as a means of connection.

The device connecting column 15 is vertically adjacent to the connecting means of the wall fixing frame member 14, has a connecting means to be connected thereto, and has a connecting piece 5 of the device main body 11 on one end face, which is the same shape as the A connecting piece 5 of the device main body 11 and is vertically connected thereto. It is a column having a B connecting piece 20 which is connected to the B connecting piece 20 . In the example, it is made of metal,
A square-shaped jetty piece 17 is made to protrude from the opening bottom of the frame member having a U-shaped cross section, and a plurality of screw holes 18 are provided on the tip surface of the jetty piece 17 to correspond to the screw holes 16 of the connecting means of the device fixing frame member 14. ing. Furthermore, the tip of one bent piece of the U-shaped frame material is bent inward at right angles to align with the side surface 19 of jetty piece 17, and the tip is further bent outward twice at right angles.
The vertically long B connecting piece 20 has the same U-shaped cross section as the A connecting piece 5 of the device main body 11.

The joint connector 21 is a vertically elongated member having the same height as the device main body 11, and connects the device main body 11 and the A and B connecting pieces 5, 20 of the device connecting column, and is further fixed to the device connecting column 15, and , which works to fill the grooves. In the embodiment, it is made of metal and has a U-shaped cross section;
The A connecting piece 5 and the B connecting piece 20 are held down by both of the protruding parts and fixed to the side surface 19 of the jetty piece 17 of the device connecting column 15 with a screw or the like from the center.

Next, to explain the order in which the present invention having the above configuration is attached to the panel 13, first, a pair of wall fixing frames 14, 14 are placed on the panel 13 side, facing each other at a position corresponding to the width of the device main body 11. Then, it is fixed to the panel 13 by screwing through the screw hole 16 on one side (fixing means). This fixation is easy to perform and maintains strength. Next, the pair of device connecting columns 15, 15 are attached to the wall fixing frames 14, 1, respectively, with the B connecting piece 20 side in front.
4, the screw hole 18 of the jetty piece 17 is inserted from the screw hole 16 of the other side (connecting means) of the wall fixing frame material 14.
Insert the screw and connect with the screw. Next, bring the device main body 11, the floor surface, the ceiling surface and the device connection column 1.
Fit it into the fitting frame formed by 5 and 15. The A connecting pieces 5 of the device main body 11 are arranged vertically in contact with the side surfaces of the B connecting pieces 20 and the jetty pieces 17 of the left and right device connecting columns 15, and the joint connectors 21 are arranged as protruding pieces. It is placed on the A and B connecting pieces 5, 20 as a wall, and fixed to the side surface 19 of the jetty piece 17 from the center with screws or the like.

Through the above steps, attachment of the device of the present invention to the panel 13 is completed. It should be noted that electrical wiring (not shown) is provided to the main body 11 of the apparatus, and input to the electrostatic precipitator 3 is made by a switch box 23.

Next, the electric circuit of the air-generating electric dust collector 3 is shown in FIG. 7, and FIG. 8 shows the principle of self-generating air that does not require a motor. The high-voltage current generated by the transformer 24 flows through an ionization wire 25, which is a thin metal wire, for example, a tungsten steel wire, and generates positive ions by high-pressure discharge, which charge surrounding floating particles. The positively charged particles are attracted to an air-generating electrode plate 26 and a counter electrode plate 27, which are vertically arranged metal flat plates such as aluminum forming negative electrodes. In this case, the positive ions emitted from the ionization line 25 are directed in the direction of the composite vector 29 (from top to bottom) that connects the ionization line 25 and the tips 28, 28 of both the wind-generating electrode plates 26, 26 in FIG. Go straight.
At this time, the viscosity of the air acts and the surrounding air is pulled along with it, creating a wind that flows from top to bottom between the vertically parallel electrode plates.

This ventilation can be obtained at a speed of about 1 m to 2 m per second, and the dust collection efficiency is extremely high at 99%. Note that a small blower fan with a silencer motor may also be used.

Now, when input is made from the switch box 23 and the wind-generating electrostatic precipitator 3 is activated, ventilation is generated that passes vertically between the vertically parallel wind-generating electrode plates 26, 26, and the warmed and rising indoor air is transferred to the device. It is sucked in from the protective net 12 of the intake port cover 9 of the main body 11,
The dust is collected and purified by the electrode plates 26 and 27 of the electric dust collector 3, cooled, and discharged into the room again after descending through the duct tube 6 and passing through the protective net 12 of the outlet cover 10.

An example of the indoor purification effect is shown in FIG. The broken line A in this graph shows the natural attenuation of suspended particles when no air purification device is used.
Curves B and C show the dust collection effect (purification effect) according to the present invention. Among these, C uses a high-speed fan with a noise-reducing motor.

As is clear from this experimental data, the air cleaning effect of the present invention is outstanding, and the width thickness of the present invention is 60 mm according to the example, and the air-cleaning effect of the present invention is 60 mm.
At the installation site, it is about 50 mm more than that, so it does not make the room feel small, and since the design is the same as or matches the existing wall or panel 13, it does not cause any discomfort.
Or, by displaying luxurious furniture that extends all the way to the ceiling, you can enhance the environment even further. Furthermore, as mentioned above, it was difficult to install air purifiers on permanent walls such as concrete walls, but according to the present invention, it is extremely easy to install, and the use of electric precipitators that have been made can now be used universally. It is possible to develop it.

In addition, since high-voltage current is discharged, from the inlet cover 9 to the outlet cover 10 of the present invention,
It is kept in an insulated state, and if necessary,
The intake port cover 9 may be used as a maintenance door, and an interlock switch (not shown) may be provided to turn off the current when this part is opened.

FIG. 9 shows another embodiment of the device main body 11 of the present invention. FIG. 10 shows an example in which the present invention is installed at a height slightly lower than the ceiling surface.

As described above, the present invention is applicable not only to one place, but also to places where a higher level of air purification is required, such as large rooms, hospitals, smoking rooms, etc.
It is best to install them in several places, facing each other.

The wall-mounted air purifying device of the present invention having the configuration and effects as described above can use existing permanent walls or panels in their current state, making it possible to avoid the difficulty of redecorating a room. living room, work room,
It has high industrial applicability, as it can be used in offices, factories, hospitals, schools, kitchens, etc., and a vacant room can be immediately converted into a smoking room, which is in high demand these days.
