Description

The present invention relates to an air partition system that blocks droplets and the like by means of airflow.

In the current situation of the corona wreck, for example, it is becoming common for restaurants to block droplets and reduce the risk of infection by partitioning between customers with acrylic partitions.

Various disadvantages have been pointed out for acrylic partitions, such as the difficulty of conversation and the sense of blockage. In addition, the employees have to repeat the sterilization work such as wiping the partition with a cloth soaked with a disinfectant, for example, every time there is a change of customers, which imposes a heavy burden.

Conventionally, air curtain devices exist. Many air curtain devices are installed on wall surfaces such as entrances and exits, and are used to block outside air (see Patent Documents 1, 2, and 3).

It is conceivable to use such an air curtain device like a partition to block the droplets of customers eating and drinking. However, a large amount of installation work is required, including the interior, and the introduction barrier is by no means low.

Also, in restaurants, the layout of dining tables may be changed according to the number of people in a group of eating and drinking customers. Although it is necessary to change the airflow according to the change in the layout of the dining table, it is not easy to change the airflow.

Furthermore, there is a risk that droplets will spread inside the store due to the air flow, and the actual situation is that it cannot be introduced easily.

Similarly, the air sucked from the suction port 214 of one of the vertical air partition devices 201 is narrowed and blown out from the blowout port 213 and sucked into the suction port 105 of the vertical ventilation fan device 101 . Between the two vertical air partition devices 201 and between one of the vertical air partition devices 201 and the vertical ventilation fan device 101, an air flow is formed in a substantially plate shape. By having the customers face each other across these plate-shaped airflows, the customers are separated by the airflows, and mutual droplet infection can be suppressed. Since the air containing droplets sucked into the vertical ventilation fan device 101 is sterilized by the sterilization filter unit 116 and then discharged, the diffusion of the droplets can be suppressed.

Further, as shown in FIG. 2, the arrangement of the vertical ventilation fan device 101 and the two vertical air partition devices 201 can be changed to an upside down layout in plan view. At that time, one vertical air partition device 201 set in an upside-down posture is placed against the vertical ventilation fan device 101, and the outlet 213 of the vertical air partition device 201 faces the intake port 105 of the vertical ventilation fan device 101. , and the other vertical air partition device 201 set in an arbitrary posture is arranged so that its outlet 213 faces the suction port 214 of one vertical air partition device 201 .

Also, the arrangement of the vertical ventilation fan device 101 and the two vertical air partition devices 201 can be easily changed to a V-shaped layout in plan view. At that time, one vertical air partition device 201 is set in a doglegged posture.

Furthermore, when viewed from the top, the arrangement of the vertical ventilating fan device 101 and the three or more vertical air partition devices 201 can be divided into two or three types: a linear layout, an inverted V-shaped layout, and a V-shaped layout. A complex layout combining layouts can be easily changed. At that time, the posture of each vertical air partition device 201 is set to a straight posture, a doglegged posture, or an inverted doglegged posture according to its arrangement.

In this way, depending on the layout of the dining table, the vertical ventilation fan device 101 and the vertical air partition device 201 may be arranged in a linear layout, a doglegged layout, an inverted doglegged layout, or a layout combining at least two of these layouts. , so that the layout of the airflow that intercepts splashes and the like can be easily changed. This layout change involves changing the positions where the vertical ventilation fan device 101 and the vertical air partition device 201 are installed on the dining table or on the floor, and blowing air to the suction port 214 of the vertical air partition device 201 according to the arrangement. Since only the angle of the exit 213 is changed, no large-scale construction work is required. In addition, since the vertical ventilation fan device 101 is provided with the bactericidal filter part 116, even if the exhaust gas of the vertical ventilation fan device 101 is recirculated in the store, it is possible to prevent the spread of infection due to the diffusion of droplets.

Further, as shown in FIG. 3, the vertical ventilating fan device 101 and the vertical air partition device 201 can be vertically stacked to separate passages according to the reciprocating direction. For example, three vertical ventilating fan devices 101 are vertically stacked with the air inlets 105 aligned in the same direction, and all the vertical air partition devices 201 are set in a linear posture, for example, three are stacked vertically, and then and arranged in a straight line along the aisle centerline. A substantially plate-shaped air flow that is elongated in the vertical direction can partition two-way passers-by from their feet to their heads, suppressing mutual droplet infection.

It should be noted that the present invention is not limited to the above-described embodiment, and various modifications can be made at the implementation stage without departing from the scope of the present invention. Further, each embodiment may be implemented in combination as appropriate, in which case the combined effect can be obtained. Furthermore, various inventions are included in the above embodiments, and various inventions can be extracted by combinations selected from a plurality of disclosed constituent elements. For example, even if some constituent elements are deleted from all the constituent elements shown in the embodiments, if the problem can be solved and effects can be obtained, the configuration with the constituent elements deleted can be extracted as an invention.
