The direction along the short side of the upper surface 11a is the front-back direction. The vertical direction corresponds to the Z-axis direction in the figure. The left-right direction is the left-right direction as seen from the user 201, and corresponds to the X-axis direction in the figure. In FIG. 2, the left side of the paper is the left direction as seen from the user 201. In FIG. 2, the right side of the paper is the right direction as seen from the user 201. The front-rear direction is the depth direction of the desk 100 with a ventilation function, which is a direction orthogonal to the vertical direction and the horizontal direction, and corresponds to the Y-axis direction in the figure. Assuming that the left-right direction is the first direction, the front-rear direction is the second direction orthogonal to the first direction in the in-plane direction of the upper surface 11a of the top plate portion 11. The in-plane direction of the upper surface 11a of the top plate portion 11 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 desk 100 with a ventilation function and the main body 1.

Specifically, the intake port 14 communicates the space on the intake side of the air blowing portion 2 in the internal air passage 16 formed inside the back surface portion 13 and the space in front of the front surface 13a of the back surface portion 13. The intake port 14 is formed below the air outlet 15 so as to open toward the front side from the back surface portion 13. When the air blower 2 operates, the air in front of the front surface 13a of the back surface 13 is sucked into the main body 1 from the intake port 14 and flows into the inside of the main body 1 from the intake port 14 to the air outlet. The airflow flows out from 15.

As shown in FIG. 2, the upper surface of the desk 100 with a ventilation function, that is, the upper surface 11a of the top plate portion 11, has a space on the exhaust side of the ventilation portion 2 in the internal air passage 16 formed inside the main body portion 1. An air outlet 15 that communicates with the outside of the main body 1 is formed. Specifically, the air outlet 15 communicates the space on the exhaust side of the blower portion 2 in the internal air passage 16 formed inside the top plate portion 11 and the space above the top plate portion 11. The air outlet 15 is formed so as to open upward toward the top plate portion 11. The upper surface 11a of the top plate portion 11 is the upper surface of the main body portion 1 and is the upper surface of the desk 100 with a ventilation function.

At the outlet 15, the airflow generated inside the main body 1 is blown upward by the operation of the blower 2. That is, the air sucked into the main body 1 is blown out from the outlet 15 to the upper side of the top plate 11. The desk 100 with a ventilation function is formed with an outlet 15, a rear outlet 151, a left outlet 152, and a right outlet 153.

The back outlet 151 is a first outlet formed in a region adjacent to the end on the back side of the upper surface 11a of the top plate portion 11. The back side outlet 151 is formed linearly along the left-right direction with the center portion in the left-right direction as the center in the back-side region of the upper surface 11a of the top plate portion 11. The opening shape of the rear outlet 151 has a larger dimension in the left-right direction than a dimension in the front-rear direction.

The left outlet 152 is a second outlet formed in a region adjacent to the left end of the upper surface 11a of the top plate portion 11. The left air outlet 152 is formed linearly along the front-rear direction in the region on the left end side of the upper surface 11a of the top plate portion 11 with the central portion in the front-rear direction as the center. The opening shape of the left outlet 152 is larger in the front-rear direction than in the left-right direction.

The right air outlet 153 is a third air outlet formed in a region adjacent to the right end portion of the upper surface 11a of the top plate portion 11. The right air outlet 153 is formed linearly along the front-rear direction in the region on the right end side of the upper surface 11a of the top plate portion 11 with the central portion in the front-rear direction as the center. The opening shape of the right air outlet 153 is larger in the front-rear direction than in the left-right direction.

The sensor unit 3 detects various states used in controlling the ventilation operation of the desk 100 with a ventilation function. The sensor unit 3 transmits the detection result to the control unit 8. The communication between the sensor unit 3 and the control unit 8 may be wireless communication or wired communication. The sensor unit 3 includes a user detection sensor unit 31 that detects that the user 201 of the desk 100 with a ventilation function is in front of the desk 100 with a ventilation function, and another person 202 other than the user 201 of the desk 100 with a ventilation function. A stranger detection sensor unit 32 for detecting the presence / absence is provided.

It is also possible. However, even if the user 201 forgets to turn on the power to the desk 100 with the ventilation function and turn off the power, in order to operate the desk 100 with the ventilation function, the desk 100 with the ventilation function is operated by using an infrared sensor or the like. It is preferable that sensor detection for detecting the presence or absence of a person in front is performed.

The other person detection sensor unit 32 detects the presence or absence of another person 202 other than the user 201 around the desk 100 with a ventilation function at a predetermined cycle. The other person detection sensor unit 32 detects another person 202 located outside the air outlet 15 when viewed from the user 201. The other person detection sensor unit 32 can detect the presence or absence of another person 202 other than the user 201 around the desk 100 with a ventilation function by using a known technique, for example, a person such as an infrared sensor using infrared rays. A motion sensor can be used. The other person detection sensor unit 32 transmits the detection result to the control unit 8.

As shown in FIG. 5, the detection range of the other person detection sensor unit 32 is the back side detection zone 321 which is the detection range on the back side of the back side outlet 151 and the left side detection which is the detection range on the left side of the left side outlet 152. There is a zone 322 and a right side detection zone 323 which is a detection range on the right side of the right side outlet 153. The other person detection sensor unit 32 detects the presence or absence of another person 202 around the desk 100 with a ventilation function for each of the back side detection zone 321 and the left side detection zone 322 and the right side detection zone 323.

The back side detection zone 321 is a region adjacent to the back side with respect to the back portion 13 in the front-rear direction. Further, the back side detection zone 321 includes a region corresponding to the back side outlet 151 in the left-right direction, and is further left and right longer than the back side air outlet 151.

The left side detection zone 322 is an area adjacent to the left side of the left side leg 121 in the left-right direction. Further, the left side detection zone 322 includes a region corresponding to the left side outlet 152 in the front-rear direction, and is further set to be a region longer in the front-rear direction than the left side outlet 152.

The right side detection zone 323 is an area adjacent to the right side of the right leg portion 122 in the left-right direction. Further, the right side detection zone 323 includes a region corresponding to the right side outlet 153 in the front-rear direction, and is further set to be a region longer in the front-rear direction than the right side outlet 153.

The operation unit 4 receives from the user various operations related to the control of the ventilation operation of the desk 100 with the ventilation function. The operation unit 4 can operate the power of the desk 100 with a ventilation function to be turned on and off. The operation unit 4 transmits information corresponding to the operation from the received user to the control unit 8.

The display unit 5 displays various information related to the control of the ventilation operation of the desk 100 with the ventilation function.

The storage unit 6 stores various information related to the control of the ventilation operation of the desk 100 with the ventilation function.

The notification unit 7 determines that there is an object on or around the air outlet 15 on the upper surface 11a of the top plate portion 11, and while the air blowout from the air outlet 15 is stopped. A warning is given to the effect that the blown air flow from the blowout port 15 has stopped. Further, the notification unit 7 determines that there is an object on or around the air outlet 15 on the upper surface 11a of the top plate portion 11, and the flow rate of the blown air flow from the air outlet 15 is reduced. During that time, a warning is given to the effect that the flow rate of the blown air flow from the outlet 15 is decreasing.

The control unit 8 controls the ventilation operation of the desk 100 with a ventilation function, including the control of each component of the desk 100 with a ventilation function. Each component of the above-mentioned desk 100 with a ventilation function can transmit and receive information to and from each other. The control unit 8 automatically controls the operation of the blower unit 2 based on the detection result of the sensor unit 3. That is, the desk 100 with a ventilation function can automatically control the operation and the air volume based on the detection result of the sensor unit 3. Specifically, the control unit 8 controls the operation of the ventilation unit 2 based on the detection result of the user detection sensor unit 31 and the detection result of the other person detection sensor unit 32.

Next, the operation of the desk 100 with a ventilation function will be described. When the power of the desk 100 with a ventilation function is turned on, the user detection sensor unit 31 and the other person detection sensor unit 32 start the detection operation at a predetermined cycle according to the control of the control unit 8. Then, the detection result of the user detection sensor unit 31 and the detection result of the other person detection sensor unit 32 are transmitted to the control unit 8. The control unit 8 controls the operation of the blower unit 2 and the stop of the blower unit 2 based on the detection result of the user detection sensor unit 31 and the detection result of the other person detection sensor unit 32.

FIG. 7 is a flowchart illustrating a procedure for operating the desk 100 with a ventilation function shown in FIG.

In step S110, the control unit 8 determines whether or not the user 201 is in front of the desk 100 with a ventilation function. Specifically, the control unit 8 determines whether or not the user 201 is in front of the desk 100 with a ventilation function based on the detection result transmitted from the user detection sensor unit 31 at a predetermined cycle. .. When the control unit 8 receives the detection result that the user 201 is detected in front of the desk 100 with the ventilation function, that is, the detection result that the desk 100 with the ventilation function is in use, the control unit 8 receives the detection result that the desk 100 with the ventilation function is in use. It is determined that the user 201 is in front of 100. When the control unit 8 receives the detection result that the user 201 is not detected in front of the desk 100 with the ventilation function, that is, the detection result that the desk 100 with the ventilation function is not in use, the control unit 8 receives the detection result that the desk 100 with the ventilation function is not in use. It is determined that there is no user 201 in front of 100.

Here, since the detection result received by the control unit 8 from the user detection sensor unit 31 is information indicating the presence or absence of the user 201 in front of the desk 100 with the ventilation function, the user is in front of the desk 100 with the ventilation function. This is user presence / absence information, which is information indicating whether or not 201 is present. Therefore, the control unit 8 receives the user presence / absence information and determines the presence / absence of the user 201 based on the user presence / absence information.

If it is determined that the user 201 is in front of the desk 100 with a ventilation function, the result is Yes in step S110, and the process proceeds to step S120. If it is determined that the user 201 is not present in front of the desk 100 with a ventilation function, the result is No in step S110, and step S110 is repeated.

In step S120, the control unit 8 determines whether or not there is another person 202 around the desk 100 with a ventilation function. That is, the control unit 8 determines the presence or absence of another person 202 other than the user 201 of the desk 100 with the ventilation function around the desk 100 with the ventilation function. Here, the periphery of the desk 100 with a ventilation function is the back side, the right side, and the left side of the desk 100 with a ventilation function, excluding the front of the desk 100 with a ventilation function. Specifically, the control unit 8 determines whether or not there is another person 202 around the desk 100 with a ventilation function based on the detection result transmitted from the other person detection sensor unit 32 at a predetermined cycle.

The control unit 8 determines the presence / absence of another person 202 around the desk 100 with a ventilation function for each of the rear side detection zone 321 and the left side detection zone 322 and the right side detection zone 323. Then, when the control unit 8 has another person 202 in at least one zone of the back side detection zone 321 and the left side detection zone 322 and the right side detection zone 323, the control unit 8 determines that the other person 202 is around the desk 100 with a ventilation function. judge. When the other person 202 does not exist in all the zones in the back side detection zone 321 and the left side detection zone 322 and the right side detection zone 323, the control unit 8 determines that there is no other person 202 around the desk 100 with the ventilation function. ..

Here, since the detection result received by the control unit 8 from the other person detection sensor unit 32 is information indicating the presence or absence of another person 202 around the desk 100 with a ventilation function, there is another person 202 around the desk 100 with a ventilation function. It is information on the presence or absence of others, which is information indicating whether or not it is present. Therefore, the control unit 8 receives the information on the presence / absence of another person, and determines the presence / absence of another person 202 around the desk 100 with a ventilation function based on the information on the presence / absence of another person.

If it is determined that there is another person 202 around the desk 100 with a ventilation function, the result is Yes in step S120, and the process proceeds to step S130. If it is determined that there is no other person 202 around the desk 100 with a ventilation function, the result is No in step S120, and step S120 is repeated.

In step S130, the control unit 8 controls to operate the blower unit 2. As a result, an air flow that flows into the internal air passage 16 of the main body 1 from the intake port 14 and flows out from the air outlet 15 is formed. That is, the control unit 8 operates the blower unit 2 only when another person 202 is present in at least one zone in each zone of the rear side outlet 151, the right side outlet 153, and the left side outlet 152.

In step S140, the control unit 8 has an outlet 15 corresponding to the zone in which the other person 202 is detected, based on the presence or absence of the other person 202 in each of the back side detection zone 321 and the left side detection zone 322 and the right side detection zone 323. The blown air flow is controlled to be blown out from the back side outlet 151, the left side outlet 152, and the right side outlet 153, respectively, and the blown air flow is controlled independently of each other. Here, the control unit 8 determines the outlet 15 from which the blown air flow is blown out according to the presence or absence of another person 202 in each zone, and the control unit 8 determines the outlet 15 corresponding to the zone where it is determined that the other person 202 is present. Controls to generate a blown air flow from the chisel. That is, the control unit 8 blows out the blown air flow from the outlet 15 corresponding to the zone where the other person 202 is determined to exist, and the blown air from the outlet 15 corresponding to the zone where the other person 202 is not determined to exist. Do not let the flow blow out.

The air outlet side internal air passage 161, the first air outlet side internal air passage 162, the second air outlet side internal air passage 163, and the third air outlet side internal air passage 164 have an outlet air passage switching unit 45. Is provided. The air passage switching unit is an air passage switching unit for switching the air passage through which the airflow flowing from the intake port 14 into the internal air passage 16 and flowing out from the air outlet 15. Examples of the blowout air passage switching unit 45 include an electric shutter and an electric damper. The operation of the blowout air passage switching unit 45 is controlled by the control unit 8.

The first outlet side internal air passage 162 is provided with a first outlet air passage switching portion 451. The first outlet air passage switching unit 451 switches between opening and closing of the first air outlet side internal air passage 162, and controls whether or not the air flow is blown out in the first air outlet side internal air passage 162. When the first air outlet side internal air passage 162 is open, the airflow which flows into the internal air passage 16 from the intake port 14 and flows out from the air outlet 15 flows, and when it is closed, the air intake port 14 The airflow that flows into the internal air passage 16 and flows out from the air outlet 15 does not flow.

The second outlet side internal air passage 163 is provided with a second outlet air passage switching portion 452. The second outlet air passage switching unit 452 switches between opening and closing of the second outlet side internal air passage 163, and controls whether or not the air flow is blown out in the second outlet side internal air passage 163. When the second air outlet side internal air passage 163 is open, the airflow which flows into the internal air passage 16 from the intake port 14 and flows out from the air outlet 15 flows, and when it is closed, the air intake port 14 The airflow that flows into the internal air passage 16 and flows out from the air outlet 15 does not flow.

When the third air outlet side internal air passage 164 is open, the airflow which flows into the internal air passage 16 from the intake port 14 and flows out from the air outlet 15 flows, and when it is closed, the air intake port 14 The airflow that flows into the internal air passage 16 and flows out from the air outlet 15 does not flow.

The control unit 8 controls the first outlet airflow passage switching unit 451 and the second outlet airflow passage switching unit 452 and the third outlet airflow passage switching unit 453 to control the first outlet side internal air passage 162 and the second outlet. Control to control whether or not the airflow is blown out in the side internal air passage 163 and the third air outlet side internal air passage 164, and to generate the blown air flow only from the air outlet 15 corresponding to the zone where it is determined that another person 202 is present. I do.

Return to the explanation in Fig. 7. In step S150, the control unit 8 determines whether or not there is another person 202 around the desk 100 with a ventilation function, as in step S120. That is, the control unit 8 determines the presence or absence of another person 202 other than the user 201 of the desk 100 with the ventilation function around the desk 100 with the ventilation function.

If it is determined that there is another person 202 around the desk 100 with a ventilation function, the result is Yes in step S150, and the process returns to step S140. If it is determined that there is no other person 202 around the desk 100 with a ventilation function, the result is No in step S150, and the process proceeds to step S160.

In step S160, the control unit 8 controls to stop the blower unit 2, and returns to step S110.

As described above, in the desk 100 with a ventilation function, the user 201 exists, and the other person 202 exists in at least one zone of each of the rear side outlet 151, the right side outlet 153, and the left side outlet 152. The blower unit 2 is operated only when, and the blown air flow is generated only from the outlet 15 corresponding to the zone in which the other person 202 exists. That is, the control unit 8 does not generate a blown air flow from the outlet 15 corresponding to the zone in which no other person 202 exists.

In this way, in the desk 100 with a ventilation function, an air curtain that blocks between the user 201 and the other person 202 is formed by a blown air flow. As a result, the air containing the droplets is prevented from being scattered between the user 201 and the other person 202 facing each other across the desk 100 with the ventilation function, and the droplets are less likely to reach the other party. As a result, it is possible to reduce the risk of virus infection of the other party caused by the virus contained in the droplets generated from one of the user 201 and the other person 202 facing each other across the desk 100 with a ventilation function.

Further, since the desk 100 with a blower function operates the blower unit 2 only when the user 201 exists to generate an air flow blown out from the outlet 15, when the user 201 does not exist in the desk 100 with a blower function. Does not generate a blown air flow, and does not generate unnecessary large power consumption or increase noise for operating the blower unit 2. Further, since the desk 100 with a ventilation function generates a blown air flow only from the outlet 15 corresponding to the zone in which the other person 202 exists, wastefully large power consumption is generated for operating the ventilation unit 2 and noise is generated. Does not grow.

Further, the desk 100 with a ventilation function is used instead of operating the ventilation unit 2 to generate an air flow blown out from the outlet 15 after a person performs actions such as breathing, talking, coughing and sneezing to generate droplets. When it is determined that the person 201 and the other person 202 exist, the blower unit 2 is operated to generate a blown air flow from the air outlet 15. As a result, in the desk 100 with a ventilation function, it is not necessary to rapidly start and operate the ventilation unit 2 with a large amount of power in order to prevent droplet infection between the user 201 and the other person 202, and the ventilation unit 2 is operated. It does not generate unnecessary large power consumption.

That is, the desk 100 with a blower function can reduce the risk of virus infection of the other party caused by the virus contained in the droplets generated from one of the people facing each other across the desk 100 with the blower function, and also the blower. It is possible to reduce the power and noise of the Noh desk 100.

In step S120 described above, the case where the detection result detected by the other person detection sensor unit 32 itself is used as the presence / absence information of another person has been described. The presence / absence information of others may be received by the control unit 8 from an external device outside the desk 100 with a ventilation function, which is installed in the installation space where the desk 100 with a ventilation function is installed. In this case, the desk 100 with a ventilation function includes a stranger presence / absence information receiving unit 9 which is a communication unit that communicates with an external device and receives other person's presence / absence information from the external device.

For example, assume that a desk 100 with a ventilation function is placed in an office where electrical equipment such as an air conditioner and lighting is installed. Even in electrical equipment such as air conditioners and lighting installed in offices, it may be possible to detect the presence or absence of a person and the position of a person with an infrared sensor or the like. In this case, the desk 100 with a ventilation function communicates with an electric device in an installation space including information on the presence or absence of a person and information on the position of a person in the office, which is the installation space in which the desk 100 with a ventilation function is installed. Information on the detection result of a person may be received as information on the presence or absence of another person and controlled. The communication between the desk 100 with a ventilation function and the electric device may be wireless communication or wired communication.

The control unit 8 can determine whether or not there is another person 202 around the desk 100 with a ventilation function based on the information on the presence or absence of a person in the office included in the information on the presence or absence of another person acquired from the electric device. Further, the control unit 8 has a person in any zone of the rear side detection zone 321 and the left side detection zone 322 and the right side detection zone 323 based on the information on the position of the person included in the information on the presence or absence of another person acquired from the electric device. You can determine if you are there.

Therefore, the other person detection sensor unit 32 may be a sensor such as an infrared sensor provided on the desk 100 with a ventilation function, as long as it can transmit the other person's presence / absence information to the control unit 8, and the other person's presence / absence information is received from an external device. It may be the receiving unit 9.

Further, the desk 100 with a ventilation function is provided with an object detection sensor unit 33. The object detection sensor unit 33 detects the presence or absence of an object existing on or around the air outlet 15 on the upper surface 11a of the top plate portion 11 at a predetermined cycle. By using a known technique, the object detection sensor unit 33 can detect the presence or absence of an object existing on or around the air outlet 15 on the upper surface 11a of the top plate portion 11, for example, infrared rays. Equipped with the infrared sensor used. The object detection sensor unit 33 transmits the detection result to the control unit 8.

FIG. 9 is a diagram showing the detection range of the object detection sensor unit 33 of the desk 100 with a ventilation function shown in FIG. 2, and is a top view of the desk 100 with a ventilation function. The detection range of the object detection sensor unit 33 is a range including the region of the air outlet 15 and the region around the air outlet 15 on the upper surface 11a of the top plate unit 11. When the air volume of the blown air flow blown out from the air outlet 15 is large, the blown air flow may hit an object at a position away from the air outlet 15. The range of the area around the outlet 15 may be set based on the air volume of the blown air flow blown out from the outlet 15.

As shown in FIG. 9, the detection range of the object detection sensor unit 33 includes the back side object detection range 331, the left side object detection range 332, and the right side object detection range 333. The back side object detection range 331 is a range including the area of the back side outlet 151 and the area around the back side air outlet 151 on the upper surface 11a of the top plate portion 11. The right object detection range 333 is a range including the area of the right air outlet 153 and the area around the right air outlet 153 on the upper surface 11a of the top plate portion 11. The left object detection range 332 is a range including the region of the left outlet 152 and the region around the left outlet 152 on the upper surface 11a of the top plate portion 11.

The control unit 8 determines whether or not there is an object existing on or around the air outlet 15 on the upper surface 11a of the top plate unit 11 based on the detection result transmitted from the object detection sensor unit 33. Further, the control unit 8 determines in which detection range the object is located based on the detection result transmitted from the object detection sensor unit 33, and the blower has an object on or around the blowout port 15. The exit 15 is determined.

The control unit 8 has an object on the air outlet 15 or around the air outlet 15 while it is determined that the object is on the air outlet 15 or around the air outlet 15 on the upper surface 11a of the top plate portion 11. Blow-out from the outlet 15 determined to be present Air flow stop control to stop the blow-out of the air flow, and blow-out from the outlet 15 determined to have an object on or around the outlet 15. One of the air flow limiting controls that reduces the flow rate of the blown air flow from the preset reference air volume can be performed.

The blown air flow blown out from the blowout port 15 has a large pressure enough to blow off an object having a relatively small mass such as paper. Therefore, when the blown air flow blown out from the blowout port 15 hits the object, a loud noise is generated or an object such as paper is blown off.

Therefore, by performing either the air flow stop control or the air flow limit control, an object on or around the air outlet 15 and the traveling direction of the blown air flow blown out from the air outlet 15 It is possible to prevent an object from being blown off and scattered by the blown air flow blown out from the air outlet 15. The object in the traveling direction of the blown air flow blown out from the air outlet 15 is, for example, a stationery shelf and a book placed on the upper surface 11a of the top plate portion 11 although it is not directly placed on the air outlet 15. Examples include documents placed on other objects.

That is, in the desk 100 with a blower function, when an object exists in the area where the blown air flow blown out from the blowout port 15 hits, one of the air flow stop control and the air flow limit control is performed. As a result, in the desk 100 with a blower function, the work object that the user 201 is working on is hit by the air blowout air flow from the outlet 15 to make a loud noise, or the outlet is made to a part of the body of the user 201. It is suppressed or prevented that a loud noise is produced by the blown air flow from 15. Further, in the desk 100 with a blower function, it is suppressed or prevented that the work object being worked on by the user 201 on the desk 100 with a blower function is blown away by the blown air flow from the blowout port 15. As a result, the user 201 of the desk 100 with a blower function can comfortably work on the desk 100 with a blower function, that is, on the upper surface 11a of the top plate portion 11.

Further, the desk 100 with a ventilation function is provided with a notification unit 7. The notification unit 7 determines that there is an object on or around the air outlet 15 on the upper surface 11a of the top plate portion 11, and while the air blowout from the air outlet 15 is stopped. A warning is given to the effect that the blown air flow from the blowout port 15 has stopped. Further, the notification unit 7 determines that there is an object on or around the air outlet 15 on the upper surface 11a of the top plate portion 11, and the flow rate of the blown air flow from the air outlet 15 is reduced. During that time, a warning is given to the effect that the flow rate of the blown air flow from the outlet 15 is decreasing. That is, the notification unit 7 notifies the user that the air flow from the air outlet 15 has stopped while the air flow stop control is being performed. Further, the notification unit 7 notifies that the flow rate of the blown air flow from the outlet 15 is decreasing while the air flow limitation control is being performed. The notification unit 7 performs notification under the control of the control unit 8.

As a result, in the desk 100 with a ventilation function, the state in which the blown air flow from the blowout port 15 is stopped is continued due to the fact that the object continues to be left within the detection range of the object detection sensor unit 33. Can be prevented. Further, in the desk 100 with a ventilation function, the flow rate of the blown air flow from the outlet 15 continues to decrease due to the fact that the object continues to be left within the detection range of the object detection sensor unit 33. It can be prevented.

Further, the state in which the blowing air flow from the blowing port 15 is stopped is a state in which there is no effect of preventing droplet infection due to the blowing air flow from the blowing port 15 between the user 201 and the other person 202. That is, the above-mentioned state has the effect of reducing the risk of virus infection caused by the virus contained in the droplets of the other party by separating the user 201 and the other person 202 by an air curtain due to the air flow blown from the outlet 15. There is no such thing. Further, when the flow rate of the blown air flow from the blowout port 15 is reduced, the effect of preventing droplet infection by the blown air flow from the blowout port 15 between the user 201 and the other person 202 is low. Is. That is, the above-mentioned state has the effect of reducing the risk of virus infection caused by the virus contained in the droplets of the other party by separating the user 201 and the other person 202 by an air curtain due to the air flow blown from the outlet 15. Is in a low state.

By notifying the alerting performed by the notification unit 7, the user 201 or another person 202 moves an object in the area within the detection range of the object detection sensor unit 33 to an area outside the detection range of the object detection sensor unit 33. The risk reduction effect of virus infection between the user 201 and the other person 202 in the desk 100 with a ventilation function can be restored to the original state.

The notification unit 7 may be one using light such as a light emitting diode (Light Emitting Diode: LED), or may be one using a buzzer sound or voice.

FIG. 10 is a flowchart illustrating an operation procedure when the control unit 8 controls the blowout of the blown air flow based on the detection result of the object detection sensor unit 33 in the desk 100 with a blower function according to the first embodiment. .. The procedure shown in FIG. 10 is performed when the blown air flow is blown out from the outlet 15.

In step S210, the control unit 8 determines whether or not there is an object on or around the air outlet 15 on the upper surface 11a of the top plate unit 11 based on the detection result transmitted from the object detection sensor unit 33. To judge.

If it is determined that there is an object on or around the air outlet 15 on the upper surface 11a of the top plate portion 11, the result is Yes in step S210, and the process proceeds to step S220. If it is determined that there is no object on or around the air outlet 15 on the upper surface 11a of the top plate portion 11, the result is No in step S210, and step S210 is repeated.

In step S220, the control unit 8 controls the blowing out of the air flow. Specifically, the control unit 8 refers to the air outlet 15 which is determined to have an object on or around the air outlet 15 based on the detection result transmitted from the object detection sensor unit 33. , Air flow stop control and air flow limit control are performed. Which of the air flow stop control and the air flow limit control is to be performed is predetermined for each outlet 15 and stored in the control unit 8.

In step S230, the notification unit 7 notifies the attention alert. Specifically, the control unit 8 notifies the notification unit 7 to alert the notification unit 7 that the blown air flow from the outlet 15 has stopped while the air flow stop control is being performed. The control is carried out so as to be performed. Further, the control unit 8 notifies the notification unit 7 of a warning that the flow rate of the blown air flow from the outlet 15 is decreasing while the air flow restriction control is being performed. To implement control.

FIG. 11 is an enlarged cross-sectional view showing an outlet opening / closing portion 41 provided at the outlet 15 of the desk 100 with a ventilation function shown in FIG. The outlet 15 may be provided with an outlet opening / closing portion 41 which is an opening / closing portion for opening / closing the outlet 15. By providing the air outlet opening / closing portion 41, it is possible to prevent an object from falling from the air outlet 15 to the internal air passage 16. The air outlet opening / closing unit 41 moves between a closed state arranged at a position where the air outlet 15 is closed and an open state arranged at a position where the air outlet 15 is opened. The opening / closing operation of the air outlet opening / closing unit 41 may be a manual operation or an automatic operation by the control unit 8. The air outlet opening / closing portion 41 can be configured by, for example, a shaft (not shown) and a shutter portion 42 that is rotatable about the shaft. In FIG. 11, the shutter portion 42 shown by the solid line shows a state in which the outlet opening / closing portion 41 is in a closed state. Further, in FIG. 11, the shutter portion 42 shown by the broken line indicates a state in which the outlet opening / closing portion 41 is in an open state.

If the air outlet 15 is always open, the work object placed on the desk 100 with a ventilation function may fall from the air outlet 15 to the internal air passage 16, and the fallen work object may be dropped by the internal wind. Work to take out from the road 16 is required. This is because it is possible to prevent the work object from falling into the internal air passage 16 by closing the air outlet 15 by the air outlet opening / closing unit 41 when the air flow from the air outlet 15 is stopped. , It is possible to prevent the trouble of the worker. The outlet opening / closing portion 41 does not have to completely close the outlet 15 as long as it can prevent an object from falling from the outlet 15 to the internal air passage 16.

Further, as shown in FIG. 11, as the other person detection sensor unit 32, an open / closed state detection sensor unit 34 that detects the open / closed state of the outlet opening / closing unit 41 may be provided. The open / close state detection sensor unit 34 detects the open / closed state of the air outlet open / close unit 41 and transmits the detection result to the control unit 8.

The control unit 8 regards the information indicating the open state of the outlet opening / closing unit 41 among the opening / closing information indicating the opening / closing state of the outlet opening / closing unit 41 as the information on the presence / absence of another person to the effect that another person 202 is present, and sets the information indicating the presence / absence of another person to the outlet. Of the opening / closing information indicating the opening / closing state of the opening / closing unit 41, the information indicating the closed state of the outlet opening / closing unit 41 is referred to as information on the presence / absence of another person, which is information on the presence / absence of another person 202. In this case, by using the detection result of the open / closed state of the outlet opening / closing unit 41 in the open / closed state detection sensor unit 34 as the information on the presence / absence of another person received by the control unit 8, the other person detection sensor unit 32 and the open / closed state detection sensor unit 34 Because it can also be used, cost reduction can be realized.

As shown in FIG. 11, as the open / close state detection sensor unit 34, a contact on / off switch that mechanically detects the open / closed state of the outlet open / close unit 41 can be used. For example, in the contact on / off switch, the open state of the outlet opening / closing unit 41 in which the open / closed state detection sensor unit 34 contacts the contact on / off switch is turned on, and the open / closed state detection sensor unit 34 does not contact the contact on / off switch. Detects the closed state as contact off. Since the contact on / off switch has a simple structure and is widely available on the market, it can be used as another person detection sensor unit 32 for detecting the presence or absence of another person 202 at a lower cost than an infrared sensor or the like.

Further, when the air outlet opening / closing unit 41 is in the closed state, the upper surface of the shutter unit 42 of the air outlet opening / closing unit 41 is made flush with the upper surface of the desk 100 with the air blowing function, so that the desk 100 with the air blowing function is easy to use. be able to. The upper surface of the desk 100 with a ventilation function, which is the work surface, is easy to use when it is flat with no unevenness. Therefore, as shown in FIG. 11, when the air outlet opening / closing unit 41 is in the closed state, the upper surface of the desk 100 with a blowing function and the upper surface of the shutter unit 42 are made to be flush with each other so that the air outlet opening / closing unit 41 can be formed. In the closed state, the upper surface of the desk 100 with a blower function becomes flat, and a desk 100 with a blower function that is easy to use can be obtained.

FIG. 12 is an enlarged cross-sectional view showing a state in which the air outlet 15 of the desk 100 with a ventilation function shown in FIG. 2 is removed from the main body 1. Since the air outlet 15 is removable from the main body 1, maintenance such as cleaning and removal of falling objects to the air outlet 15 becomes easy. Since air flows through the outlet 15, foreign matter such as dust adheres to the outlet 15 if it is used for a long time. However, it is difficult to clean the outlet 15 because it is difficult for a hand, a nozzle of a vacuum cleaner, or the like to enter. Further, since the air outlet 15 opened on the upper surface of the desk 100 with a blower function is open at the upper side, the work object on the desk 100 with a blower function is likely to fall.

Therefore, by making the outlet 15 removable as shown in FIG. 12, it becomes easier to clean the mechanical portion housed inside the desk 100 with a ventilation function such as the outlet opening / closing portion 41, and maintenance is easy. Further, by making the outlet 15 removable, it is possible to easily take out a fallen object that has fallen into the outlet 15 when the outlet 15 is removed.

In this case, the air outlet 15 includes a storage unit 154 in which the air outlet opening / closing unit 41 and the open / close state detection sensor unit 34 are housed, and a flange portion 155 extending outward from the upper end portion of the storage unit 154. The storage portion 154 has a box shape with an open upper surface. Further, the storage unit 154 has an opening (not shown) that communicates the inside of the storage unit 154 with the internal air passage 16. The flange portion 155 is formed larger than the upper surface of the box-shaped storage portion 154. As a result, the flange portion 155 is supported on the upper surface of the desk 100 with a blower function, and the storage portion 154 is supported on the upper surface of the desk 100 with a blower function. The storage portion 154 is detachable from the end of the internal air passage 16 to form an outlet 15.

The intake port 14 can be attached and detached in the same manner as the air outlet 15, so that it becomes easier to clean the intake port 14 when a mechanism portion such as an opening / closing portion that can be housed inside the desk 100 with a ventilation function is attached. Is easy. Further, by making the intake port 14 removable, it is possible to easily take out an object that has entered the intake port 14 when the intake port 14 is removed.

Further, FIG. 13 is an enlarged cross-sectional view showing a state in which the wind direction plate 46, which is a wind direction adjusting portion, is provided at the air outlet 15 of the desk 100 with a ventilation function shown in FIG. As shown in FIG. 13, a wind direction adjusting portion is provided at the outlet 15, and the blowing direction is variable, so that a feeling of cool breeze can be obtained when necessary. The wind direction adjusting unit makes the blowing direction of the blown air flow blown out from the outlet 15 variable from the vertical direction toward the user 201 side. That is, when it is hot such as in summer, the wind direction of the blown air flow blown out from the outlet 15 is set to the direction in which the wind hits the user 201 of the desk 100 with the blowing function.
