JP 2002-145409 A Japanese Patent Laid-Open No. 10-28696

In various service industries such as banks and travel agencies, employees often face and respond at short distances from visitors. In hospitals and the like, doctors who perform interviews and patients approach each other, and employees and patients also face and receive explanations and exchange medical expenses at reception. In this way, there are many cases where a plurality of people face each other and have a conversation, but due to breathing, vocalization, coughing or sneezing, saliva etc. scatters from the mouth, and others inhale the splashes. There is a fear. In particular, doctors and service workers who respond must always face an unspecified number of people, and are exposed to the risk of infectious diseases caused by droplets.

Wearing a mask is conceivable as a method for preventing splashing and inhalation of splashes, but the impression given to the other party becomes worse and is difficult to implement in the hospitality business. In addition, the provision of shielding objects such as glass creates a sparse impression, and the physical partitioning of the space impedes the movement of people and objects, making it a major change to facilities and rooms for installation. To force.

The air curtain described in Patent Document 1 or the like blocks a certain space from the outside and prevents intrusion of foreign matters such as dust, but does not have a function of preventing the movement of splashes scattered from a person's mouth. . On the other hand, Patent Document 2 describes that droplets are captured / removed. However, as described in paragraphs 0002 and subsequent paragraphs of the document, air droplets are used when cutting a patient's teeth in dental practice. In this case, the fine powder of the cut teeth generated at that time, various germs in the oral cavity, blood of the patient, etc. are scattered. In this document, it is not spattering of saliva or the like generated by coughing or sneezing, or conversation or breathing or vocalization. In the first place, in a state where the teeth are being cut, the patient cannot utter, cough or sneeze, and there is no room for the generation of droplets as the subject of the present invention. The patient is lying down with his face under the dentist and not in a face-to-face condition. A horizontal air curtain is then formed on the patient's face.

An object of this invention is to provide the method and apparatus which can prevent the movement of the splash between several persons who face each other, without physically dividing space with a structure.

In order to solve the above-mentioned object, according to the method of preventing splash movement of the present invention, a columnar member that stands upright is placed between a first space where a first person is present and a second space where a second person is present. , Air is sent out from one columnar member in a strip shape, air is sucked into the strip by the other columnar member, an air curtain is formed between the first space and the second space, and a splash between the first space and the second space Prevent movement of objects.

Moreover, the air curtain apparatus for blocking splashes of the present invention is provided between a first space where a first person is present and a second space where a second person is present, and the splash between the first space and the second space. An air curtain device for blocking splashes that prevents movement of an object, having a columnar member that faces upright, one columnar member has an air outlet that sends out air in a strip shape, and the other columnar member is a strip shape And an air inlet for sucking air, and an air curtain is formed between the first space and the second space. It is preferable that the filter and the germicidal lamp are provided on at least one columnar member. In addition, each of the columnar members may have a blower, a blower port for sending air in a band shape, and an intake port for sucking air in a band shape to form a two-layer air curtain that flows in opposite directions. Further, three or more columnar members can be provided side by side, and an air curtain can be formed between adjacent columnar members.

The droplet movement preventing method and the droplet blocking air curtain device according to the present invention form an air curtain between people facing each other, and prevent splashes from the opponent from being scattered around. It has a simple structure, is easy to install and remove, and there is no need to make major changes to the installation location or facility. Prevents the movement of splashes, but does not interfere with the movement of people and materials.

It is sectional drawing which shows 1st Example of the air curtain apparatus for a droplet blocking. It is sectional drawing which shows the modification of a columnar member. It is a perspective view which shows 2nd Example of the air curtain apparatus for a droplet blocking. It is the horizontal sectional view. It is a horizontal sectional view showing a 3rd example of an air curtain device for splashes interception. It is a horizontal sectional view showing the 4th example of the air curtain device for splash thing interception.

The form for implementing this invention is demonstrated. FIG. 1 is a perspective view showing an outline of an air curtain device for blocking splashes. The air curtain apparatus 1 for blocking splashes has a first columnar member 2 and a second columnar member 3 installed opposite to the first columnar member 2. One of the columnar members has a blower port that sends out air in a band shape, and the other columnar member has an intake port that sucks air into the band shape. Here, the first columnar member 2 has a blower port 4, and the second columnar member 3 has an intake port 5. Furthermore, the air curtain apparatus 1 for blocking splashes includes a blower 6. In this example, the blower 6 is provided outside the columnar members 2 and 3, and is connected to the first columnar member 2 and the second columnar member 3 by flexible blower tubes 7 and 8 that are easily deformed. The discharge side of the blower 6 is connected to the first columnar member 2, and the intake side of the blower 6 is connected to the second columnar member 3.

A wide plate 9 is provided at the base of the columnar members 2 and 3 as an installation member for installation on the table. A tripod 10 is attached to the lower side of the second columnar member 3 so that it can be installed on the floor.

The usage method and operation of the air curtain device for blocking splashes will be described. Here, it demonstrates based on the example used in the examination room of a medical institution.

Here, it is assumed that a patient and a doctor (not shown) face each other at a short distance in a medical examination or the like. In FIG. 1, there is a doctor (first person) on the back side, and the space is a first space 12. On the other hand, there is a patient (second person) on the front side, and the space is defined as a second space 13. And the columnar members 2 and 3 are installed between both facing.

When the blower 6 is operated, air is sent to the first columnar member 2, and air is discharged from the blower port 4 in a band shape. On the other hand, the 2nd columnar member 3 is attracted | sucked by the air blower 6, and the inlet port 5 inhales air in strip shape. Thus, a band-shaped air flow from the first columnar member 2 toward the second columnar member 3 is generated, and the air curtain 14 is formed between the two facing each other.

The air curtain 14 restricts the movement of air between the first space 12 and the second space 13. By adjusting the height at which the air curtain is formed to the position of the face of the person facing, the air flow caused by conversation or coughing is blocked. Therefore, even if a mask or the like is not worn, it is possible to prevent the other from sucking splashes generated from one such as saliva.

The air curtain itself is invisible and the patient is seldom aware of its existence. Therefore, it is possible to touch at a short distance while giving an intimate impression. By facing each other without a mask, you can feel the other party's facial expression and have a sense of security. Even if you auscultate or take a pulse, the air curtain will not interfere.

The splash curtain air curtain device 1 has a very simple structure and can be implemented at low cost. Installation and removal is easy, and there is no need to make major modifications to rooms and facilities.

It is easy to carry and can be applied even when consulting outside a medical facility. For example, school doctors can bring them when they go to school for group checkups, etc., and they can be installed at special examination venues. Risk is reduced.

As described above, the application in a medical institution has been described as an example. However, the droplet movement preventing method and the droplet blocking air curtain device can be widely used in addition to this. An unspecified number of customers visit and face employees at reception desks and counters in various service industries such as banks and travel agencies. Such a window can be easily installed, and the movement of splashes between people facing each other can be prevented. It is useful in various service industries because it can respond in an intimate atmosphere without giving a distant impression to the other party.

A first embodiment of the present invention will be described. FIG. 2 is a cross-sectional view showing an outline of the first embodiment of the air curtain apparatus for blocking splashes. The air curtain apparatus 1 for blocking splashes has a first columnar member 2 and a second columnar member 3 installed opposite to the first columnar member 2. The first columnar member 2 has a blower port 4, and the second columnar member 3 has an intake port 5.

Inside the first columnar member 2 is a blower 6 such as a turbo fan or a sirocco fan, on which a blow pipe connecting portion 15 is provided. Further, there is a relatively wide space from the blower 6 to the blower opening 4, and a germicidal lamp 16 is provided there. A filter 17 is attached near the blower 6. The first columnar member 2 and the second columnar member 3 are connected by a blower pipe 7.

The first columnar member 2 and the second columnar member 3 are installed between people facing each other. It is preferable to install so as to cover the mouth completely so that the surface connecting the air blowing port 4 and the air intake port 5 is located in front of the face of the person facing.

By the action of the blower 6, the air sucked from the intake port 5 is supplied to the first columnar member 2 through the blower pipe 7, discharged from the blower port 4, and flows into the intake port 5 again. Thus, a band-shaped air flow from the first columnar member 2 toward the second columnar member 3 is generated, and the air curtain 14 is formed between the two facing each other.

This air curtain 14 restricts the movement of air between the two spaces where each person is located. Even if saliva or the like is discharged in conversation or coughing, the splashes are captured by the air curtain 14 and are prevented from moving to the other.

Air containing splashes is sucked through the intake port 5 and sent to the filter 17. As the air passes through the filter, splashes and dust are adsorbed. Since the air thus purified passes near the germicidal lamp 16, pathogens such as germs can be safely treated.

FIG. 3 is a cross-sectional view showing a modification of the columnar member. This modification has the same structure as that of the first columnar member in FIG. 2, but the blower pipe connecting portion 15 is provided on the surface opposite to the blower port 4. Therefore, it is preferable to use a flexible air duct such as a flexible hose.

When the blower tube is attached, the air circulation is the same as in the example of FIG. 2, and the air curtain device operates as a splash blocker. When the blower pipe is removed and the blower pipe connection part 15 is opened, indoor air is taken in from the blower pipe connection part 15, purified by the filter 17 and the germicidal lamp 16, and clean air is discharged from the blower opening 4. . Therefore, it can be used as an air cleaner.

A second embodiment of the present invention will be described. FIG. 4 is a perspective view showing a second embodiment of the air curtain device for blocking splashes, and FIG. 5 is a horizontal sectional view thereof.

In this embodiment, two independent portable columnar members 2 having the same structure are used. The columnar member 2 has an upright quadrangular columnar shape and includes a blower 6 such as a sirocco fan inside. In addition, a slit-like air outlet 4a and an air inlet 5a are provided in parallel on one surface of the quadrangular prism. And the partition plate 18 has protruded outside between the ventilation port 4a and the inlet port 5a. And the ventilation port 4b and the inlet port 5b are provided also in the surface facing this. Furthermore, a door 19 for opening and closing the air blowing port 4b and the air intake port 5b is also provided.

The two columnar members 2 are installed facing each other at a predetermined distance. At this time, the one air inlet 4a and the other air inlet 5a face each other. Since the two columnar members 2 are independent members, the interval can be selected relatively freely. Also, the rear door 19 is closed.

When the sirocco fan (blower 6) is operated, an air flow as shown by an arrow in FIG. 5 is generated. The air sucked from the air intake port 5a turns around the columnar member 2 and is discharged as a band-like flow from the air blowing port 4a. For example, the blower port 4 of the right columnar member 2 in FIG. 4 is located on the front side, and the intake port of the left columnar member 2 is in front of it. Therefore, an air curtain 14a that flows from the right to the left in the drawing is formed on the front side. Further, an air curtain 14b that flows in the opposite direction is formed on the far side. As described above, a two-layer air curtain that flows in opposite directions is formed. Since the partition plate 18 is provided between the two layers of the air curtain, interference of the air flow between the air curtains is prevented. By providing the two columnar members 2 between the persons facing each other, a two-layer air curtain is formed between the two members, and the movement of the splashes is effectively prevented.

If only two columnar members 2 are used facing each other as in this embodiment, the air blowing port 4b, the air intake port 5b, and the door 19 on the back surface need not be provided.

A third embodiment of the present invention will be described. FIG. 6 is a horizontal cross-sectional view showing a third embodiment of the air curtain apparatus for blocking splashes. The second embodiment is developed and the columnar member 2 shown in FIGS. 4 and 5 is used.

The spray curtain blocking air curtain device has three or more columnar members 2. The three or more columnar members are provided so as to be continuously arranged on the same line. Here, the term “substantially on the same line” includes a case where the action / effect of the present invention is essentially achieved even if the curve is not only a perfect straight line but also a gentle curve.

Of the three or more columnar members, the two at both ends are installed in a state where the air blowing port 4b and the air intake port 5b on the surface facing the outside are closed. In the columnar member placed in the middle part, the door 19 is opened to open the air blowing port 4b and the air intake port 5b.

The flow of air will be described by focusing on one columnar member 2b in the middle part. First, the lower air curtain 14a in FIG. 6 will be described. The air sent from the blower port 4b of the columnar member 2c on the right side flows into the intake port 5a of the columnar member 2b. And it passes through the inside of the columnar member 2b without changing the direction, and is sent to the intake port 5a of the columnar member 2a adjacent to the left side from the blower port 4b. Thus, the air curtain 14a facing left is formed between the left and right columnar members 2a and 2c. Similarly, a right air curtain 14b is formed by the air blowing port 4b and the air intake port 5a shown on the upper side in FIG.

As described above, since the intermediate columnar member passes through the inside without changing the direction, a smooth flow with little energy loss is realized. Moreover, since there is no restriction | limiting in the number of columnar members of an intermediate part, Arbitrary numbers of columnar members can be installed as needed and an air curtain can be formed continuously.

A fourth embodiment of the present invention will be described. FIG. 7 is a horizontal sectional view showing a fourth embodiment of the air curtain apparatus for blocking splashes. As in the third embodiment, three or more columnar members 2 are continuously installed. In the columnar member 2 of this embodiment, a blower port 4 is provided on a certain side surface, and an intake port 5 is provided on a side surface adjacent thereto. Therefore, the air flowing in from the intake port 5 changes its direction by 90 degrees in the columnar member 2 and is discharged from the blower port 4.

As shown in FIG. 7, by arranging the four columnar members 2 at the positions of the four corners of the rectangle, a circulating belt-like air flow is created. Thus, the rectangular space can be partitioned by the four air curtains. For example, if the bed of an infectious patient is surrounded, the splash of the patient can be prevented from being scattered outside. A person who comes to visit can talk to the patient without inhaling the patient's droplets as long as they are outside. In addition, the patient is also protected from external foreign matter.

When air is circulated as in this embodiment, a single air curtain can be formed by the columnar member 2 provided with one air blowing port 4 and one air intake port 5 as shown in FIG. Moreover, the air inlet 4 and the air inlet 5 may be provided on each of two adjacent side surfaces to form a two-layer air curtain that flows in opposite directions. In this case, a wider area can be surrounded by inserting a columnar member as shown in FIGS.
