It is composed of a second short side side surface 1f arranged on the short side side and extending along the short side of the upper surface 1a. The main body case 1 has a quadrangular pyramid shape having a horizontally long shape in the left-right direction.

In the first embodiment, the direction perpendicular to the upper surface 1a is the vertical direction, the direction along the long side of the upper surface 1a is the left-right direction, and the direction along the short side of the upper surface 1a is the front-back direction. The vertical direction corresponds to the Z-axis direction in the figure. The left-right direction corresponds to the X-axis direction in the figure. The front-back direction corresponds to the Y-axis direction in the figure. Assuming that the left-right direction is the first direction, the front-back direction is the second direction orthogonal to the first direction in the in-plane direction of the upper surface 1a. The in-plane direction of the upper surface 1a is a direction parallel to the horizontal direction. Further, the first direction, which is the left-right direction, can be rephrased as the longitudinal direction of the desktop blower 100 and the main body case 1. Further, the second direction, which is the front-rear direction, can be rephrased as the lateral direction of the desktop blower 100 and the main body case 1.

The upper surface 1a and the lower surface 1b have a rectangular shape and are arranged in a parallel state. The first long side side surface 1c and the second long side side side surface 1d have a trapezoidal shape having the same size and the same shape, and are arranged in a state of facing each other. The first short side side surface 1e and the second short side side side surface 1f have a trapezoidal shape having the same size and the same shape, and are arranged in a state of facing each other. Since the tabletop blower 100 is installed on the tabletop, the upper surface 1a and the lower surface 1b are installed in a state parallel to the horizontal plane.

The long side direction of the upper surface 1a, the long side direction of the lower surface 1b, the long side direction of the first long side side surface 1c, and the long side direction of the second long side side side surface 1d are the same directions parallel to each other. , The same direction as the left-right direction. Therefore, the longitudinal direction of the upper surface 1a, the longitudinal direction of the lower surface 1b, the longitudinal direction of the first long side side surface 1c, and the longitudinal direction of the second long side side surface 1d are the same directions parallel to each other and are desktop. It is the same direction as the longitudinal direction of the mold blower 100.

Further, the short side direction of the upper surface 1a and the short side direction of the lower surface 1b are the same directions parallel to each other and the same directions as the front-back direction. Therefore, the lateral direction of the upper surface 1a and the lateral direction of the lower surface 1b are the same directions parallel to each other, and are the same directions as the lateral direction of the desktop blower 100.

The main body case 1 is formed with a suction port 2 for sucking air around the main body case 1 and an outlet 3 for blowing out the air sucked inside the main body case 1 to the outside of the main body case 1.

The inside of the main body case 1 and the outside of the main body case 1 communicate with each of the first long side side surface 1c and the second long side side side surface 1d, which are two long side side surfaces facing each other with the upper surface 1a in between. The suction port 2 is formed. The suction port 2 is formed linearly along the longitudinal direction of the upper surface 1a on the lower end side, that is, the lower surface 1b side of each of the first long side side surface 1c and the second long side side side surface 1d. That is, the suction port 2 is formed at a position lower than the outlet 3 in the height direction. Further, the suction port 2 penetrates the long side side surface in the thickness direction and is formed over the entire width of the long side side surface in the long side direction. That is, the suction port 2 is formed by opening in the front-rear direction.

The suction port 2 extends in the left-right direction in parallel with the air outlet 3, and becomes parallel to the horizontal direction when the tabletop blower 100 is installed on the table. The opening shape of the suction port 2 has a larger dimension in the left-right direction than a dimension in the height direction. Further, the left-right dimension of the suction port 2 is about the same as the left-right dimension of the air outlet 3. Further, the suction port 2 is formed in the shape of one slit continuous in the left-right direction. However, the suction port 2 does not necessarily have to be formed over the entire width of the upper surface 1a.

Inside the main body case 1, a filter portion 11 that covers the suction port 2 from the inside of the main body case 1 is provided. The filter unit 11 purifies the air sucked into the main body case 1 through the suction port 2. When a person breathes, talks, coughs, and sneezes, small droplets of water splash from the person's mouth. The filter unit 11 can collect the virus contained in the droplets by collecting the droplets scattered from the mouth of a person in the vicinity of the tabletop blower 100. That is, the filter unit 11 can collect the virus contained in the droplets by collecting the droplets scattered from the mouth of the person facing the desktop blower 100.

An air filter generally used for a blower can be used for the filter unit 11. Further, by using a HEPA filter (High Efficiency Particulate Air Filter) for the filter unit 11, it is possible to enhance the air purification capacity of the desktop air blower 100. Further, by using a dust collector such as an electrostatic precipitator for the filter unit 11, it is possible to enhance the air purification capacity of the desktop type blower 100.

On the upper surface 1a of the main body case 1, an outlet 3 that communicates the inside of the main body case 1 and the outside of the main body case 1 is formed.

Has been done. The cutout portion 4 can be rephrased as a recess formed on the upper surface 1a side, which is formed between two facing side surfaces on the long side in the front-rear direction and connects the two facing side surfaces on the long side. The position of the lower surface 4a of the notch 4 in the height direction is lower than that of the suction port 2. The cutout portion 4 has a part of the lower surface 1b of the main body case 1 recessed toward the upper surface 1a side, and is independent of the air passage through which air flows inside the main body case 1.

In the notch 4, for example, a person sitting facing the first long side side surface 1c and a person sitting facing the second long side side surface 1d eat with the tabletop blower 100 sandwiched between them. Things such as spoons, forks and receipts can be handed over through the notch 4 when you are. Therefore, two people sitting with the tabletop blower 100 sandwiched between them can pass an object to the other side without worrying about the air flow.

Further, inside the main body case 1, a blower 12 which is a blower unit for forming an air flow that flows into the inside of the main body case 1 from the suction port 2 and flows out from the air outlet 3 is housed. The blower 12 has a fan 12a that forms an air flow that flows into the inside of the main body case 1 from the suction port 2 and flows out from the air outlet 3, and a motor 12b that rotationally drives the fan 12a.

Further, as shown in FIGS. 3 and 4, a duct portion 13 for guiding the air flow generated by the blower 12 is housed inside the main body case 1. The duct portion 13 is provided in a shape that guides the airflow blown from the blower 12 toward the air outlet 3.

As shown in FIG. 4, two blowers 12 are arranged in parallel inside the main body case 1. Each blower 12 includes a duct portion 13. By extending the dimensions of the main body case 1 in the longitudinal direction and increasing the number of blowers 12 housed inside the main body case 1, it is possible to configure the desktop blower device 100 further extended in the longitudinal direction. ..

A power supply unit 14 for collectively operating the blower 12 is provided on the first short side side surface 1e, which is the short side side surface. The power supply unit 14 supplies the electric power required for the blower 12 to operate. The power supply unit 14 is connected to an external power source (not shown), and power is supplied from the external power source. An operation unit (not shown) for operating the operation of the blower 12 to operate the desktop blower device 100 is provided on the outer surface of the power supply case 14a constituting the housing of the power supply unit 14. It is also possible to use a battery that can be charged by the electric power supplied from an external power source (not shown) for the power supply unit 14.

A sensor unit 15 is provided on the side surface of the power supply case 14a of the power supply unit 14. The sensor unit 15 detects various states around the tabletop blower 100. That is, the sensor unit 15 detects various states around the main body case 1. The sensor unit 15 has a resident sensor that detects a person at a position facing the tabletop blower 100 in the front-rear direction, and a CO that detects the concentration of carbon dioxide (CO ₂ ) in the air around the tabletop blower 100. ₂ sensors, a vocal sensor that detects the voice of a person who is facing the desktop blower 100 in the front-rear direction, an attitude sensor that detects the posture of a person who is facing the desktop blower 100 in the front-back direction, etc. Various sensors can be used.

Next, the operation of the desktop blower 100 will be described. When the power of the desktop type blower 100 is turned on, electric power is supplied from the power supply unit 14 to the blower 12, and the blower 12 operates. By operating the blower 12, an air flow that flows into the inside of the main body case 1 from two suction ports 2 facing each other in the front-rear direction and flows out from the air outlet 3 is formed. As a result, the air around the two suction ports 2 facing each other in the front-rear direction is sucked into the inside of the main body case 1. Then, the air sucked into the main body case 1 is blown upward from the outlet 3 to the outside of the main body case 1.

That is, by operating the blower 12, an air flow from the lower side of the blower 12 to the upper side of the blower 12 is formed inside the main body case 1. As a result, the air around the first long side side surface 1c of the main body case 1 and the air around the second long side side side surface 1d flow into the inside of the main body case 1 through the suction port 2. Then, the air sucked into the main body case 1 flows upward from the air outlet 3 to the outside of the main body case 1.

The air blown out from the outlet 3 becomes an upward airflow. The upward airflow forms an air curtain that blocks the people facing each other across the tabletop blower 100 in the front-rear direction. That is, an air curtain is formed that blocks a person who is on the first long side side surface 1c side of the main body case 1 and a person who is on the second long side side side surface 1d side of the main body case 1.

As a result, in the tabletop blower 100, air containing droplets generated from people facing each other across the tabletop blower 100 in the front-rear direction is purified by the filter unit 11, and an air curtain is formed by the purified air. .. As a result, the air containing the droplets is prevented from being scattered in the front-rear direction to the opponent facing the tabletop blower 100, and the droplets are less likely to reach the opponent. This makes it possible to reduce the risk of virus infection of the other person caused by the virus contained in the droplets generated from one of the people facing each other across the tabletop blower 100 in the front-rear direction.

Then, since the tabletop blower 100 sucks air into the main body case 1 from both sides of the tabletop blower 100 in the front-rear direction through the suction port 2, the tabletop blower 100 faces each other across the tabletop blower 100 in the front-back direction. It is possible to prevent the droplets generated from the person who does the work from staying and spreading to the surroundings. This makes it possible to reduce the risk of virus infection of people around the tabletop blower 100 due to the virus contained in the droplets generated from the people facing each other across the tabletop blower 100.

The amount of splashes scattered from the mouth is relatively small. In this case, even if the air volume of the blower portion 112 is reduced, the droplets scattered from the mouth of a person at a position facing the desktop blower device 100 in the front-rear direction are surely sucked into the inside of the main body case 1 from the suction port 2. I can put it in.

That is, the control unit 117 can change the air volume of the blower unit 112 by comparing the voice volume or sound pressure detected by the voice sensor unit 152 with the voice threshold value. Further, the control unit 117 may gradually increase the air volume of the blast unit 112 from zero in direct proportion to the sound pressure of the utterance detected by the utterance sensor unit 152.

Further, the control unit 117 controls to reduce the air volume of the blower unit 112 when the voice of a person is not detected within a predetermined threshold time in the control state where the air volume of the blower unit 112 is large. Can be done.
