Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an air supply grill with a negative ion generator.
[0002]
[Prior art]
Negative ions stimulate the parasympathetic nerves that work when the mind and body are relaxed during normal times, or give a healing effect by increasing the proportion of alpha waves that are the frequency components of the electroencephalogram generated in a relaxed state. It is known that it has an effect of reducing fatigue and removing fatigue. Therefore, conventionally, negative ion generators for supplying negative ions have been widely used in homes and office buildings. Conventional negative ion generators of this type generally include an ion generator having a needle electrode opposed to a ground electrode in a plastic case, and a DC high-voltage power supply for supplying a DC high voltage to the ion generator. Are installed in living rooms, bedrooms, tables, study desks, etc.
[0003]
The DC high voltage sent to the ion generator has its negative potential applied to the needle electrode, and its positive potential applied to the ground electrode, so that air passes between the needle electrode and the ground electrode. When the air is ionized, a large amount of negative ions is generated.
[0004]
[Problems to be solved by the invention]
However, the conventional negative ion generator has a problem that negative ions are generated only in the vicinity of the position where the negative ion generator is installed, and the entire room cannot be filled with negative ions. In order to solve this problem, a configuration in which a fan or the like is provided in the negative ion generator is conceivable, but this causes another problem that the apparatus is increased in size and cost.
[0005]
Therefore, it is conceivable to fill the room with negative ions by combining it with an air supply grille, but it is impossible to incorporate a negative ion generator into an air supply grille, etc., even if it can be built in a smaller size. The negative ions are charged on the plastic cover portion of the air supply grille and are not released to the outside.
[0006]
An object of the present invention is to provide an air supply grill with a negative ion generator capable of solving the above-mentioned problems in the prior art.
[0007]
[Means for Solving the Problems]
In order to solve the above-described problem, in the present invention, a negative ion generation module having a ground electrode and a needle electrode is incorporated in an air supply grill to effectively generate negative ions.
[0008]
According to the present invention, a supply air grille with a negative ion generator, possess a supply receiving opening and supply dispensing opening, the air supply from the air supply receiving opening cylindrical fuselage section An air supply grille comprising a main body configured to be sent to the air supply / delivery opening, an air volume adjusting plate provided in the main body, and a front cover attached to the air supply / delivery opening; A negative ion generating module attached to the air volume adjusting plate, and a power supply device for supplying a DC high voltage to the negative ion generating module, and the power supply device said negative ion generator module and Ri formed and a high voltage connection cable for connecting said plurality of needle electrodes, wherein the faces of the different direction from the air blowing direction in the body portion, and of the body portion Negative ion generator with air supply grille, characterized in that attached as arranged at intervals in direction is proposed.
[0009]
According to the invention of claim 2, in the invention of claim 1, a non-metallic conductive sheet is disposed in the supply grill on the downstream side of the negative ion generation module. The device is disposed in an insulated state separately from the conductive sheet, the negative ion generation module, and the air supply grille, and the ground potential of the power supply device, the conductive sheet, and the negative ion generation module are arranged. An air supply grill with a negative ion generator is proposed in which electrical connection is made so that the ground potential of the air supply grille and the ground potential of the air supply grille have the same potential.
[0010]
As described above, since the negative ion generating module is mounted and fixed on the air volume adjusting plate of the supply grill, the flow of air circulating through the supply grill is not hindered. Even when the front cover is mounted on the air supply grille, the non-metallic conductive sheet effectively prevents the front cover from being charged, and negative ions are efficiently released. As a result, the negative ions generated from the negative ion generation module are released well together with the air passing through the supply grill.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an exemplary embodiment of the present invention will be described in detail with reference to the drawings.
[0012]
FIG. 1 is an exploded perspective view showing an embodiment of an air supply grill with an anion generator according to the present invention. A reference numeral 1 generally indicates an air supply grill incorporating a negative ion generator, and the air supply grill 1 is installed on the ceiling surface of each part for ventilation of a house or central heating. It is an example.
[0013]
The air supply grill 1 includes a main body 2, an air volume adjusting plate 3 provided in the main body 2, and a front cover 4. The main body 2 is configured by attaching a cylindrical body 2B to a frame-shaped frame 2A, and a rear end 2Ba, which is a small-diameter cylindrical portion of the body 2B, is connected to the air supply duct 5. Yes. Air supplied from an air supply duct 5 connected to a blower (not shown) is sent into the main body 2 from an air supply receiving opening at the rear end 2Ba, and sent out indoors through the air supply opening 2Aa of the frame 2A. It is.
[0014]
The front cover 4 is configured to be detachably attached to the frame 2A by appropriate known means, and the material thereof is an appropriate plastic material for preventing condensation. Between the frame 2A and the front cover 4, a filter sheet 6 for removing dust contained in the air supply and a conductive sheet 7 that functions to prevent the front cover 4 from being charged are disposed. It has a configuration.
[0015]
In order to include negative ions in the air supplied from the supply air grill 1 configured as described above, and to efficiently send the negative ions into the room or the like, the air volume adjusting plate 3 includes a negative ion. An ion generation module 8 is mounted and fixed.
[0016]
In FIG. 2, the attachment state of the negative ion generation module 8 is shown enlarged. The negative ion generation module 8 will be described with reference to FIG. 1 and FIG. 2. The negative ion generation module 8 has a plurality of needle electrodes 82 provided on an insulating substrate 81 made of an appropriate known electrical insulating material. In both cases, a U-shaped ground electrode 83 is provided so as to face these needle electrodes 82. The needle electrode 82 may be directly fixed to the insulating substrate 81, but may be detachably attached to the insulating substrate 81 via an appropriate socket so as to ensure easy replacement.
[0017]
The negative ion generation module 8 can be fixed to the air flow adjusting plate 3 using a double-sided adhesive tape, screwing, or other appropriate means using a Z-shaped fixing bracket or the like. Good. Alternatively, the negative ion generating module may be housed in a plastic case, and the plastic case may be fixed to the air volume adjusting plate 3 by a double-sided adhesive tape, screwing, or other appropriate means.
[0018]
As can be seen from FIG. 2, the negative ion generation module 8 is mounted on the air volume adjusting plate 3 such that the needle electrodes 82 are arranged at intervals in the radial direction of the body portion 2B. The supply air from the supply air duct 5 is efficiently ionized in the negative ion generation module 8.
[0019]
The air supply from the air supply grill 1 is normally about 1 m / s, and the negative ion generation module 8 is attached to the air volume adjusting plate 3 as described above, so that the air supply from the air supply duct 5 is supplied by the negative ion generation module 8. It is ionized extremely efficiently and a large amount of negative ions can be generated.
[0020]
The required direct-current high voltage for operating the negative ion generation module 8 is supplied from a power supply device 9 separately disposed in an appropriate form in the vicinity of the main body 2. The DC high voltage output from the power supply device 9 is sent to the negative ion generation module 8 via the high voltage cable 10. The high-voltage cable 10 is a high-voltage application connection cable for connecting the power supply device 9 and the negative ion generation module 8 to apply a DC high-voltage from the power supply device 9 between the plurality of needle electrodes 82 and the ground electrode 83. It is. Here, a ground wire 10a is drawn out on the ground electrode 83 side, and a lead wire 10b that applies a high DC voltage as a cathode is drawn out on the needle electrode 82 side with a length of about 30 cm. A negative potential is applied to the eighth needle electrode 82 and a positive potential is applied to the ground electrode 83, whereby a required DC high voltage is applied between the needle electrode 82 and the ground electrode 83.
[0021]
Negative ions generated by applying a DC high voltage to the negative ion generation module 8 are sent into the room through the front cover 4, but the front cover 4 is made of plastic as described above. The cover 4 becomes negative ions and is charged. For this reason, the generated negative ions are almost charged over the front surface of the supply grill 1, and the negative ions generated one after another repel each other and are not released to the outside through the front cover 4.
[0022]
For this reason, a conductive sheet 7 is disposed between the front cover 4 and the main body 2 of the air supply grill 1, and the conductive sheet 7 is separated from the air supply grill 1 and is electrically insulated. The power supply device 9 is configured to have the same potential as the ground potential. In the present embodiment, the conductive sheet 7 is electrically connected to the ground electrode 82 of the negative ion generation module 8 to another ground wire 11 in parallel with the ground wire 10a of the high-voltage cable 10 via the clip terminal 12, Thus, the conductive sheet 7 can be set to a required ground potential. Since the clip terminal 12 is detachable from the conductive sheet 7, a required ground connection to the conductive sheet 7 can be easily performed. In this way, the conductive sheet 7 arranged as described above is connected to the ground potential of the negative ion generating module 8 and the power supply device 9 arranged in an insulated state separately from the supply grill 1 and the same potential configuration. Therefore, the charge removal of the front cover 4 is effectively performed.
[0023]
In the present embodiment, the conductive sheet 7 is substantially the same size as the front cover 4 and is in the form of a conductive sheet made of conductive plastic having a plurality of rectangular grooves 7a. It is not limited to. In addition, the installation location of the conductive sheet 7 is not limited to the above-described example. For example, a non-metallic conductive sheet 7 may be provided in the supply grill 1 and downstream of the negative ion generation module 8. Also in this case, the conductive sheet 7 can be connected to the ground potential of the power supply device 9 to obtain the same charge removal effect.
[0024]
Therefore, a required high DC voltage is supplied from the power supply device 9 to the negative ion generation module 8 through the high voltage cable 10 as described above, and is ionized when the supply air passes through the negative ion generation module 8. Then, the negative ions generated thereby are easily passed through the front cover 4 from which the charge is removed by the conductive sheet 7 and supplied to the room. Note that the power supply device 9 can be embedded in a room, for example.
[0025]
As described above, in the above embodiment, the negative ion generation module 8 is attached to the air volume adjusting plate 3, and the power supply device 9 is configured to be separated and independent so as to be disposed outside the main body 2. The negative ion generation module 8 and the power supply device 9 can be integrated and fixed to a fixing bracket of another shape and accommodated in the main body 2.
[0026]
Since the air supply grill 1 is configured as described above, unlike the case where the negative ion generator is simply installed on the table of the room, the air passing through the air supply grill releases more negative ions into the room. Is done. In a room of about 8 tatami mats, it is possible to fill the room with about 2400 to 3000 negative ions / CC by installing only one air supply grill 1 according to this configuration. It is done. Further, since the negative ion generation module 8 is mounted and fixed on the air volume adjusting plate 3 of the air supply grill 1 in a separate and independent form, the main body 2 has a configuration in which only a small unit is inserted, and the circulating air cannot be prevented. An effect is obtained. And since it can comprise easily using the negative ion generation module 8, the power supply device 9, and the electroconductive sheet 7, the effect that manufacturing cost can also be made comparatively low is also acquired.
[0027]
【Example】
In the embodiment shown in FIG. 1, the result of measuring the amount of negative ions generated when the distance between the needle electrode 82 and the ground electrode 83 is 16 mm and the high DC voltage applied between them is −2 KV is shown in FIG. 2. As a measuring instrument, ITC-201A manufactured by Andes Electric was used. The measurement distance is a linear distance from the device under measurement to the ion counter. All measured values are average values of measurements for 30 minutes (3600 times). The installation position of the measuring instrument is the same for any measurement.
[0028]
FIG. 2 shows a comparison of the amount of negative ions generated when the negative ion generation module 8 is incorporated into a supply grill installed at a height of 2.4 m and when it is not incorporated. The negative ion amount was measured simultaneously for 30 minutes at positions 2 m, 2.5 m, and 3 m away from the supply grill.
[0029]
FIG. 3 shows a comparison of the amount of negative ions generated with and without a negative ion generator when a conventional negative ion generator accommodated in a plastic case is installed on a table in the same room. .
[0030]
From the above measurement results, it can be seen that in the embodiment of the present invention incorporated in the air supply grille, the generation of negative ions is remarkably increased by the passing air.
[0031]
【The invention's effect】
According to the present invention, since the negative ion generator is not simply installed on the table in the room, but is incorporated in the air supply grill, more negative ions are generated in the room by the air passing through the air supply grill. Ions are released and the effect of forest bathing is obtained while in the room. In addition, since only the ion generating portion is mounted and fixed on the air volume adjusting plate of the air supply grille, the effect of not obstructing the circulating air can be obtained. Furthermore, since the front cover can be effectively prevented from being charged, the generated negative ions can be effectively delivered into the room. In addition, since the structure is simple, it is possible to obtain an effect that the manufacturing cost can be relatively low.
