Description

The present application discloses a wind direction adjusting device for an air conditioning outlet and an ion generating device thereof.

Various buildings such as buildings, shops, hospitals, and houses are equipped with air conditioners for air conditioning in the rooms. Air conditioners include types that are embedded in the ceiling or walls, types that are suspended from the ceiling, and types that are installed on the wall. .

By the way, since the specific gravity of air is inversely proportional to temperature, warm air accumulates in the upper part of the room. In addition, cold air accumulates in the lower part of the room. Therefore, the air conditioner, for example, when performing a cooling operation, blows out cold air from the air conditioning outlet toward the lower part of the room so that the warm air that accumulates in the upper part of the room can be efficiently sucked in and the air can be conditioned. Therefore, in order to prevent the cool air blowing out from the air conditioning outlet from hitting people in the room, for example, a device for adjusting the wind direction of the air conditioning outlet, such as that shown in Patent Document 1, is commercially available.

In recent years, there has been an increasing interest in preventive measures against viruses floating in the air and various other means of purifying the air. However, viruses, for example, are finer than pollen or particulate matter (PM). Therefore, viruses cannot be collected by filters of air conditioners. Moreover, when a filter capable of collecting viruses is attached to the suction port or outlet of the air conditioner, the air permeability is significantly reduced, resulting in a significant deterioration in the performance of the air conditioner.

Therefore, it has been proposed to provide an ion generator for generating negative ions that kill and activate viruses near the air outlet of the air conditioner. However, since the ion generator is relatively large as an article to be attached to the air outlet of the air conditioner, the impact on aesthetics and air flow is not small.

Therefore, the present application provides a wind direction adjustment device for an air conditioner outlet and an ion generator capable of generating negative ions at the outlet of the air conditioner while suppressing the effect on the aesthetic appearance and air flow of the air conditioner. Disclose.

In order to solve the above problems, in the present invention, an ion generator is placed on the air conditioning outlet side of the face plate portion of the wind direction adjusting device.

Specifically, the present invention is an airflow direction adjustment device for an air conditioning outlet, which is a face plate portion disposed in front of the air conditioning outlet through which the air that has been air-conditioned to the air conditioner blows out and receives the air blown out from the air conditioning outlet. a mounting portion for mounting the face plate portion in front of the air conditioning outlet; and an ion generator that is placed on the face plate portion on the air conditioning outlet side of the face plate portion and generates ions.

With such a wind direction adjusting device, since the ion generator is mounted on the face plate portion on the air conditioning outlet side of the face plate portion, it is difficult for a person below the wind direction adjusting device to visually recognize it. Therefore, the influence of the ion generator on the aesthetics of the wind direction adjusting device can be suppressed as much as possible.

In addition, the ion generator may generate ions with electric power fed through a power cable fixed to the mounting portion. According to this, the influence on aesthetics can be suppressed as much as possible.

Moreover, the wind direction adjusting device has a ventilation hole through which the air blown out from the air conditioning outlet can pass, and may further include a cover that covers the ion generating device. According to this, it is possible to prevent the user from touching the ion generator.

Further, the ion generator may be a device in which a needle of a needle-shaped discharge electrode for generating ions is protruded upward.

With such a wind direction adjusting device, since the needle of the needle-shaped discharge electrode that generates ions projects upward, the air blown out from the air conditioning outlet is directed to the upper side of the ion generator. will flow. Therefore, the tip of the needle of the needle-shaped discharge electrode is shaped to receive a headwind slightly obliquely with respect to the direction of the tip. For this reason, the adhering matter tends to move from the tip side of the needle of the needle-shaped discharge electrode to the root side. As a result, the tip of the needle of the needle-shaped discharge electrode is likely to be kept exposed without being covered with deposits.

Further, with such an airflow direction adjusting device, the air blown out from the air conditioning outlet flows toward the upper surface of the main surface portion of the airflow direction adjusting device. Then, the air that reaches the upper surface of the main surface portion of the wind direction adjusting device flows along the upper surface. Since the ion generator having the needles of the needle-like discharge electrodes protruding upward is placed on the upper surface, the air that reaches the upper surface of the main surface naturally flows along the upper surface of the ion generator. become. Therefore, turbulence of the airflow caused by the ion generator can be suppressed as much as possible.

Further, in the ion generator, the needles of the needle-like discharge electrodes may protrude upward from the upper surface parallel to the surface of the air conditioning outlet side of the face plate portion. According to this, the air that has reached the upper surface of the main surface portion flows along the upper surface of the ion generator parallel to the upper surface of the main surface portion. can be suppressed.

The ion generator may also have a dielectric electrode surrounding the needle of the needle-like discharge electrode. Here, "enclose" is not a concept of completely surrounding, but a concept including a state of partially surrounding, for example. According to this, the needle discharge electrode can be protected.

The present invention also provides, for example, an ion generator provided in any one of the above-described wind direction adjusting devices for air conditioning outlets, comprising: an ion generator main body for generating ions; a substrate for fixing to a face plate; It may be an ion generator of a wind direction adjusting device of an air conditioning outlet.

With the wind direction adjustment device for air conditioning outlets and the ion generator therefor, it is possible to generate negative ions at the air outlet of the air conditioner while suppressing the effects on the aesthetics and air flow of the air conditioner. be.

Embodiments of the present invention will be described below. The embodiment shown below is one form of the present invention, and the technical scope of the present invention is not limited to the following embodiment.

FIG. 1 shows an example of a mounting state of a wind direction adjusting device 3 that adjusts the wind direction of air blown out from an air conditioning outlet 2 of an air conditioner 1. As shown in FIG. As shown in FIG. 1, the wind direction adjusting device 3 is arranged in front of an air conditioning outlet 2 through which air that has been air-conditioned by the air conditioner is blown out, and a wing plate 4 (in this application, a wing plate) that receives the air blown out from the air conditioning outlet 2 and an arm 5 for attaching the wing plate 4 to the front of the air conditioning outlet 2 (which is an example of the "mounting portion" in the present application).

FIG. 2 is a perspective view of the wind direction adjusting device 3. FIG. 3 is an exploded perspective view of the wind direction adjusting device 3. FIG. The wing plate 4 is made of plastic or other synthetic resin, and has a generally rectangular, shallow-bottomed container-like shape. The wing plate 4 has wall portions 7L, 7S, 7S erected at right angles to the main surface portion 6 at both longitudinal direction edges and the remaining one side edge except for one side edge of the main surface portion 6 thereof. . The wall portion 7L is a wall portion extending along the long sides of the generally rectangular wing plate 4 . The walls 7S, 7S are walls extending along the short sides of the wing plate 4. As shown in FIG. The wing plate 4 has a curved portion 8 that is continuous with the main surface portion 6 and gently curved at one side edge where the wall portions 7L, 7S, 7S are not formed.

The upper surface of the main surface portion 6 is provided with three reinforcing ribs 9 erected at equal intervals along the longitudinal direction of the main surface portion 6, and the wing plates 4 exhibiting the overall shape of a container with a shallow bottom are formed into four ribs. It is partitioned into three compartments 10L, 10CL, 10CR and 10R. Two of the three reinforcing ribs 9 are provided with hinges 11 for attaching the arm 5 to the wing plate 4 so as to be rotatable about one axis.

Further, the wind direction adjusting device 3 is equipped with an ion generator 15 . The ion generator 15 is a device that generates ions, and is fixed to the wing plate 4 via the substrate 14 . The ion generator 15 is fixed to the substrate 14 by screwing screws inserted through the screw holes 15A into screw holes of the support projections 14B arranged on the surface of the plate member 14A. The substrate 14 is fixed in a state of being placed on the sections 10CL and 10CR of the main surface portion 6 of the wing plate 4 by being engaged with the claws 13F and 13R which are provided for fixing the heat insulating mat. be.

FIG. 4 is a perspective view of the ion generator 15. FIG. The ion generator 15 is an ion generator in which an operation button 15B, an electrical insulator 15D, a dielectric electrode 15E, and a needle discharge electrode 15F are arranged on an upper surface 15C of a substantially rectangular parallelepiped housing. The ion generator 15 has a needle discharge electrode 15
Two F's are placed. 15 C of upper surfaces become a surface parallel to the main surface part 6 in the state which the ion generator 15 was fixed to the wing plate 4 through the board|substrate 14. As shown in FIG. The ion generator 15 operates with power supplied via the power cable 15G. The power cable 15G can be fixed by fitting into a groove formed in the arm 5 so as not to impair the aesthetics of the wind direction adjusting device 3 . Therefore, the power cable 15G can be integrated with the arm 5. As shown in FIG.

When the operation button 15B is pushed to activate the ion generator 15, a positive voltage is applied to one of the two needle-like discharge electrodes 15F. As a result, a plasma region is formed by electric discharge due to a potential difference between the needle-shaped discharge electrode 15F and the dielectric electrode 15E surrounding the needle-shaped discharge electrode 15F from the side, and water molecules in the air are electrically decomposed. , mainly hydrogen ions H ⁺ are produced. Since the dielectric electrode 15E has a shape surrounding the needle of the needle-shaped discharge electrode 15F, it can also protect the needle-shaped discharge electrode 15F. Then, water molecules in the air aggregate around the generated hydrogen ions H ⁺ to form positive cluster ions H ⁺ (H ₂ O)m (m is an arbitrary integer) (hereinafter referred to as “positive ions”). is formed.

A negative voltage is applied to the other of the two acicular discharge electrodes 15F. As a result, a plasma region is formed by electrical discharge due to a potential difference between the needle-shaped discharge electrode 15F and the dielectric electrode 15E, and water molecules in the air are electrically decomposed to mainly generate oxygen ions O ²⁻ . be. Then, water molecules in the air aggregate around the generated oxygen ions O ²⁻ to form negative cluster ions O ²⁻ (H ₂ O)n (n is an arbitrary integer) (hereinafter referred to as “negative ions”). ) is formed.

As shown in FIGS. 2 and 3, the wind direction adjusting device 3 is provided with a cover 16 for preventing the user from accidentally touching the needle-like discharge electrodes 15F and the like. The cover 16 is a cover plate member 16A provided with a large number of ventilation holes 16B. The ventilation hole 16B is of a size that a user's finger cannot pass through. Further, the cover 16 is provided with a notch 16C for preventing the arm 5 from interfering with the cover plate member 16A.

FIG. 5 is a cross-sectional view of the wind direction adjusting device 3 taken along line AA shown in FIG. As can be seen from FIG. 5 , the air blown out from the air conditioning outlet 2 of the air conditioner 1 flows toward the upper surface of the main surface portion 6 of the wind direction adjusting device 3 . Then, on the upper surface of the main surface portion 6 , the flow changes to flow along the upper surface of the main surface portion 6 . Here, as can be seen from the direction of the air shown in FIG. The flow is directed toward the upper surface 15C of the ion generator 15 placed on the upper surface of the ion generator 15 as well. For this reason, the tip of the needle of the needle-shaped discharge electrode 15F is shaped to receive a headwind slightly obliquely to the direction of the tip.

The tip of the needle of the needle-like discharge electrode 15F is a portion for forming a plasma region by discharge due to a potential difference, as described above. Therefore, the tip of the needle of the needle-shaped discharge electrode 15F must not be covered with deposits such as dust. In this regard, in the wind direction adjusting device 3 of the present embodiment, the tips of the needles of the needle-like discharge electrodes 15F are configured to receive a slightly oblique headwind. Therefore, in the wind direction adjusting device 3 of the present embodiment, it is difficult for dust or other deposits to adhere to the tips of the needles of the needle-like discharge electrodes 15F. Even if an adhering substance such as dust adheres to the needle of the needle-shaped discharge electrode 15F, the tip of the needle of the needle-shaped discharge electrode 15F is exposed to a slightly oblique headwind. It is easy to move from the tip side of the needle to the base side of the needle discharge electrode 15F. As a result, the tip of the needle of the needle-shaped discharge electrode 15F is likely to be kept exposed without being covered with the adhering matter.

The wind direction adjusting device 3 is arranged in front of the air conditioning outlet 2 of the air conditioner 1 as described above. The air conditioner 1 is usually provided with a filter at the air conditioner intake port in order to suppress adhesion of dust or other matter to the heat exchanger inside the machine. Therefore, the air blown out from the air conditioning outlet 2 of the air conditioner 1 is purified to some extent by the filter provided in the air conditioner 1 . However, it is difficult for the filter provided at the air conditioning inlet of the air conditioner 1 to collect fine dust and the like. For this reason, although the air blown out from the air conditioning outlet 2 of the air conditioner 1 is purified to some extent, it may deposit dust and other contaminants on the acicular discharge electrodes 15F of the wind direction adjusting device 3 . However, in this embodiment, as described above, the tip of the needle of the needle-shaped discharge electrode 15F is exposed to the slightly oblique headwind flowing from the air conditioning outlet 2, so that the air passing through the filter of the air conditioner 1 is exposed. Even if fine dust or the like adheres to the needle-like discharge electrode 15F, the adhered matter tends to move from the tip side to the root side of the needle discharge electrode 15F. As a result, the tip of the needle-shaped discharge electrode 15F is kept exposed without being covered with the deposit, and ions continue to be generated appropriately.

Further, in the above embodiment, since the ion generator 15 is mounted on the air conditioning outlet 2 side of the main surface portion 6, the ion generator 15 can be seen from the indoor occupants below the wind direction adjusting device 3. Difficult to see. Therefore, the influence of the ion generator 15 on the aesthetics of the wind direction adjusting device 3 can be suppressed as much as possible.

Further, in the above-described embodiment, the air blown out from the air conditioning outlet 2 of the air conditioner 1 flows toward the upper surface of the main surface portion 6 of the wind direction adjusting device 3 . The upper surface 15C of the ion generator 15 is parallel to the upper surface of the main surface portion 6 against which the air blown from the air conditioning outlet 2 hits. Therefore, the air hitting the ion generator 15 flows along the upper surface 15</b>C parallel to the upper surface of the main surface portion 6 . Therefore, even though the ion generator 15 is placed on the upper surface of the main surface portion 6 , the wind direction adjusting device 3 suppresses the turbulence of the airflow caused by the ion generator 15 as much as possible.

In the above embodiment, the ion generator 15 having two needle-like discharge electrodes 15F is provided in the wind direction adjusting device 3, but the wind direction adjusting device 3 has, for example, three or more needle-like discharge electrodes 15F. The form which provided the ion generator 15 may be sufficient. Moreover, although the ion generator 15 is fixed to the wing plate 4 via the substrate 14 in the above embodiment, it may be fixed directly to the wing plate 4 . Further, in the above-described embodiment, the needle-shaped discharge electrodes 15F are provided to protrude upward, but the needle-shaped discharge electrodes 15F may be provided in other forms. Also, the ion generator 15 may be a device that generates ions with a non-needle-shaped discharge electrode instead of the needle-shaped discharge electrode.

Also, in the above-described embodiment, only one wind direction adjusting device 3 is provided for one air conditioning outlet 2 , but a plurality of airflow direction adjusting devices 3 may be provided for one air conditioning outlet 2 . Further, although only one wind direction adjusting device 3 is provided for one air conditioner 1 as shown in FIG.

Further, in the above-described embodiment, the wind direction adjusting device 3 has a form in which the ion generating device 15 is operated by electric power supplied from the outside through the power cable 15G. It may operate on battery power. Further, the wind direction adjusting device 3 may operate the ion generating device 15 with electric power generated by itself using wind power or the like.

In the above embodiment, the wind direction adjusting device 3 is provided at the air conditioning outlet 2 of the air conditioner 1, which is a ceiling-mounted air conditioner, but may be provided at the air conditioning outlet of a wall-mounted air conditioner.
