Abstract

To provide an exhalation discharge device in order to solve the problem that although as countermeasures for infection diseases such as novel coronaviruses and influenza, it is often necessary to ventilate a room, or other than that, partitions are being used, it is difficult to eliminate the risk of droplet infection in a case of holding a meeting or eating using conventional partitions.SOLUTION: The present invention pertains to a device that provides an exhalation discharge pipe on a partition or wall, etc., and allows exhalation to be discharged to the outside on a per-person basis, where a duct fan, etc. can be forcibly exhausted at a terminal portion.SELECTED DRAWING: Figure 1

Description

TECHNICAL FIELD The present invention relates to an indoor environment improvement against droplet infection by discharging exhaled air to the outside through a partition plate placed on a table or a wall surface.

Conventional ventilation was often done for the entire room, and it was not a drastic measure against infectious diseases caused by droplet infection, such as opening the window twice an hour, which is the recommended number of ventilation times, or twice an hour. Moreover, although it is common to provide a partition plate so that the droplets do not fly directly, it was not possible to suppress the diffusion of the droplets in an enclosed space.

JP 2011-041686

The problem to be solved by the present invention is indoor ventilation, which is performed as a countermeasure against infectious diseases such as the new coronavirus and influenza. As another measure, it is difficult to eliminate the risk of droplet infection when holding a meeting or eating with a partition (partition plate) installed to prevent droplet infection.

The present invention is a device that provides an exhalation discharge pipe on a partition (partition plate) or wall so that exhalation can be discharged to the outside on a per-person basis. .

By installing the expiratory discharge device of the present invention, it is possible to take measures against droplet infection, which is considered the most important measure against infectious diseases such as the new coronavirus and influenza, such as meeting rooms, customer service, and restaurants.

It is a side explanatory view showing the outline of the device provided in the living space. It is a plane explanatory drawing which shows the outline|summary of the apparatus provided in living space. It is drawing which shows the structural outline when the exhalation apparatus attached to the partition (partition plate) installed on the table is installed alone. It is drawing which shows the structural outline when the expiratory-discharge apparatus attached to the partition (partition board) installed on the table is installed continuously.

Hereinafter, for convenience of explanation, an arbitrary direction in a horizontal plane is called an X direction, a direction perpendicular to the X direction in a horizontal plane is called a Y direction, and a direction perpendicular to both the X and Y directions is called a Z direction.

FIG. 1 and FIG. 2 are explanatory diagrams showing the outline of the device provided in the living space.
As shown in this figure, in a general living room, it was common to ventilate by opening a window or a ventilation fan F in order to expel exhaled air generated by conversation.

Figure 3 Figure 4 is a drawing of the expiratory device.
In the drawings, T is a table, P is a partition (partition plate), PS is a partition stand, and F is a ventilation fan.
D indicates a duct fan, 10 is a main duct, 11 is a pipe connecting the exhalation exhaust pipe and the main duct, 12 is an exhalation exhaust collection pipe, 12A is a cap, 12B is an elbow, and 12C is an exhalation exhaust collection pipe. A socket used in this case, 12M, indicates a mounting jig for the exhaled air collecting tube, and 12H indicates a hole provided in the exhaled air collecting tube.

As shown above, it is possible to efficiently collect and discharge the exhaled air from a person by installing a partition (partition plate) placed on the table or 12 exhaled air collecting pipes attached to the wall. did. Exhaust is done with a duct fan, and by exhausting outside the wall or to the fan on F, it is a countermeasure against droplet infection.

The expiratory discharge collecting tube of the present invention has a structure that can be used even if several tubes are connected. In this case, it is necessary to consider the balance between the D duct fan and the F exhaust fan.

It should be noted that the present invention is not limited to the above-described embodiments, and it goes without saying that various modifications can be made without departing from the gist of the present invention.
