Description

TECHNICAL FIELD The present invention relates to a collecting pipe type inlet structure, and a sterilization device and an exhaust device using the same.

Recently, due to the spread of viruses, measures against infectious diseases are required in theaters, television stations, residences, offices, buildings, public facilities, hospitals, nursing care facilities, etc.

As a countermeasure, conventional products already exist that absorb, purify, and emit air.

For example, Patent Document 1 discloses that an indoor sterilizer equipped with a light source that irradiates ultraviolet rays into the interior of the housing, a member that narrows down the ultraviolet rays from this light source, a fan, etc. is attached to the wall of the room, and the air below the room is Disclosed is a sterilizer that sterilizes food by moving it upward and irradiating it with ultraviolet rays.

Further, Patent Document 2 discloses an air cleaner including a vertical housing having an air intake port formed on the lower side surface and an air supply port formed on the upper side.

Further, Patent Document 3 discloses an air purifier including a vertical duct with an intake port formed on the side surface and an air outlet formed at the bottom.

However, since the device in Patent Document 1 is configured to sterilize the entire room, for example, airborne air may float near performers (wind blowers, singers, theater performers, sit-down speakers, etc.) who locally emit a large amount of exhalation on stage. The effectiveness of measures against bacteria, viruses, etc. is limited and low.

Furthermore, although the device of Patent Document 2 can be installed near the performer, it is not able to efficiently draw in the exhaled air emitted by the performer because air is taken in from the lower part.

Further, in Patent Document 3, air is taken in from the side of the vertical duct, so it is possible to take in air from above and below, but since the air intake port is provided on the side of the duct, it is possible to take in air evenly from above and below. Inhalation may not be possible.

The present invention has been made in view of the above-mentioned problems, and its purpose is to provide a collecting pipe type intake port structure that can effectively take in air even in a local space, and a sterilization device and an exhaust device using the same. It is about providing.

In order to solve the above problems, a collecting pipe type intake port structure according to the present invention includes a collecting pipe in which a plurality of pipe bodies each having an intake port are collected in the longitudinal direction , and the collecting pipe has a plurality of pipe bodies each having an intake port. The collecting pipe is configured such that the positions thereof are different in the axial direction of the tube , and the collecting pipe is configured such that the intake ports of the plurality of tubes are arranged in a spiral .

Preferably, the collecting pipe is configured such that a plurality of pipe bodies are arranged concentrically.

Moreover, it is preferable that the intake port is inclined with respect to the axial direction of the tube body.

Furthermore, the sterilizer according to the present invention is characterized by including the present collecting pipe type inlet structure.

Further, the plurality of tube bodies 21 are configured such that the positions of the intake ports 20 are different in the axial direction of the tube body 21.

That is, the plurality of pipe bodies 21 of the collecting pipe 22 are configured such that the central pipe 23 is the highest, and the peripheral pipes 24 are successively lower in height in a spiral manner, whereby the intake ports 20... are arranged in a spiral pattern.

Note that the spiral shape is a string-wound shape or a conch-like shape, and in short, it is a three-dimensional spiral shape.

Further, each intake port 20 is formed to be inclined with respect to the axial direction of the tube body 21 so as to face outward in the radial direction of the housing 2 .

It is preferable that this collecting pipe type intake port structure 4 can take in 20 times the amount of air (for example, 0.6 cubic meters) as the exhaled air.

Further, the material of the collecting pipe type intake port structure 4 is preferably plastic, acrylic, etc. in order to reduce the weight.

Furthermore, it is preferable that the plurality of intake ports 20 be arranged so as to cover a height difference of about 30 cm from the performer's chest to the top of the head.

In such a configuration, as shown in FIG. 3, when the control section 16 activates each section with the power on/off switch SW of the operation section 5 and drives the fan motor 14 with the suction on/off switch SW, performer A's exhaled air is The air containing the air is sucked into the housing 2 through the plurality of intake ports 20 of the collecting pipe type intake port structure 4, flows along the germicidal lamp 9 (in the direction of the arrow), and is irradiated from the germicidal lamp 9. It is sterilized by ultraviolet light.

The sterilized air is discharged from the lower part of the casing 14 through the plurality of exhaust ports 7 of the discharge side holding section 8.

In other words, a maximum of 30,000 [cc] (0.03 [m ³ ] ) of exhaled air per minute exhaled by Performer A enters the cylindrical housing 2 along with 0.6 [m ³ ] of air, which is 20 times the amount of exhaled air. It will be sucked in, sterilized and discharged.

According to the above configuration, the sterilizer 10 forcibly sucks the exhaled breath of Performer A into the interior, kills bacteria etc. by irradiating the sucked air with ultraviolet rays, and exhausts the air, thereby preventing Performer A from becoming a cause of infection. It can be done. That is, effective sterilization can be performed in a local space.

Furthermore, since performer A's exhaled air is sterilized by ultraviolet light in the immediate vicinity, bacteria, viruses, etc. floating in the space around the performer can be sterilized. In particular, it is very effective in countering bacteria and viruses floating in the surrounding space produced by performers who emit large amounts of exhalation on stage. Furthermore, it is possible to carry out artistic and cultural activities without endangering the health of other performers or the audience.

Furthermore, since the intake ports 20 are arranged in a spiral configuration, air can be effectively taken in even in a localized space, and sterilization can be performed efficiently.

That is, in the case of suction using a single suction port as shown in the prior art, only the air immediately surrounding the suction port (for example, air in a space approximately 10 cm above the suction port) can be suctioned, but the suction port 20... By arranging the suction ports 20 in a spiral configuration, the air around each of the suction ports 20 is suctioned, and air can be effectively suctioned over a wide range.

Therefore, as described above, by arranging the intake ports 20 in a spiral shape so as to cover the height difference of approximately 30 cm from the chest of performer A to the top of the head, air containing exhaled breath from performer A can be absorbed. It can be sterilized by suction.
