  The present invention relates to a moisture recovery device and a mobile weather experience device.

There is a mobile weather experience device that can move to a desired place by a vehicle or the like as a mobile weather experience device that artificially produces weather conditions and allows an experienced person to experience various weather conditions.
As such a mobile weather experience device, for example, there is a rain experience device described in Patent Document 1 described later. This rain experience device is a device in which a set of devices including an experience room for reproducing rain is mounted on a vehicle, and has a spray device for spraying water into the experience room.
Moreover, this rain experience apparatus has the waste_water | drain collection | recovery means which collect | recovers the water which fell to the floor, and can reuse now the water spread from the spraying apparatus.

JP-A-11-258972 (paragraphs [0010] to [0024] and FIGS. 1 and 10)

In such a mobile weather experience device, when not only rain but also storms are reproduced simultaneously, a blower is used in the experience room.
However, when the experience room is a closed room, the air flow generated by the blower device is trapped in the experience room, so the air blowing efficiency is poor, and in order to obtain the desired wind speed, it is more than the power required in the open space. Power was needed.
On the other hand, when the experience room is an open space or has a vent, a part of the water sprayed from the spray device is discharged outside the experience room on the air flow generated by the blower For this reason, the water recovery rate by the waste water recovery means decreases. In the mobile weather experience device, there is a limit to the amount of water that can be mounted, so when the water recovery rate is low in this way, the time during which rain can be produced will be shortened.

  The present invention has been made in view of such circumstances, and is capable of effectively recovering water droplets in an airflow passing through a vent hole while minimizing a decrease in the flow rate of the airflow. It aims at providing a collection | recovery apparatus and a mobile weather experience apparatus using the same.

In order to solve the above-described problems, the moisture recovery device and the mobile weather experience device of the present invention employ the following means.
That is, the moisture recovery device according to the present invention is a moisture recovery device that recovers moisture contained in the airflow passing through the ventilation port, and is arranged in a row in the vertical direction of the ventilation port and has a gap between them. A plurality of slats are provided, and each slat is inclined with respect to a horizontal plane so that the downstream end of the ventilation port is located above the upstream end of the ventilation port. And a plate-like slat body provided, and a lip provided at the downstream end of the slat body so as to protrude from the upper surface of the slat body. apparatus.

The airflow that has flowed into the ventilation port provided with the moisture recovery device configured as described above passes through the gaps between the blades of the moisture recovery device and flows downstream of the ventilation port.
The slat body constituting each slat is inclined with respect to the horizontal plane so that the end on the downstream side is located above the end on the upstream side. The flowing airflow hits the upper surface of the slat body of each slat, and the direction of the flow is changed to the direction of rising along the top surface. For this reason, the water droplet contained in this airflow strikes the slat body by the inertial force and adheres to the slat body.
Then, the air flow rising along the upper surface of the slat body hits a lip protruding from the upper surface of the slat body, and the direction of the flow is changed to a direction around the lip. For this reason, the water droplet contained in this air current strikes the lip by the inertial force and adheres to the lip.
The water droplets adhering to the slat body and the lip flow down to the upstream end portion (that is, the lower end portion) of the slat body through the lip and the slat body by the action of gravity, and fall to the upstream side of the ventilation port.

In this way, in this moisture recovery device, since the water droplets in the airflow are collected by changing the direction of the airflow passing through the ventilation opening, there is little resistance to the airflow passing through the ventilation opening, and the airflow passing through the ventilation opening is reduced. Water droplets in the airflow passing through the ventilation port can be effectively recovered while minimizing the decrease in the flow rate.
Further, since the structure of each slat is simple, the moisture recovery device can be small and light, and the manufacturing cost can be reduced.
And since there is little resistance with respect to the airflow which passes a ventilation opening, the noise which arises by passage of an airflow is also few.

  In this moisture recovery apparatus, the lip may be provided so as to be inclined so as to approach the upper end side of the slat body as it goes from the connecting part side to the slat body toward the tip.

  In this case, since the lip is inclined with respect to the airflow flowing along the upper surface of the slat main body, there is little resistance to the airflow passing through the ventilation opening.

  Each of the slats may be swingable about a horizontal axis perpendicular to the ventilation direction of the vent hole.

In this case, the interval between the blades and the inclination angle of the blade body can be adjusted by swinging the blades around the horizontal axis.
For example, by increasing the inclination angle of the slat body with respect to the horizontal plane, the change angle of the direction of the airflow by the slat body increases, and water droplets contained in the airflow passing through the vent can be collected more effectively. it can.
Moreover, the resistance with respect to the airflow which passes a ventilation opening reduces by making the inclination-angle with respect to the horizontal surface of a slat board main body small.

  Each of the slats may be capable of contacting a slat located above by swinging around the horizontal axis.

  In this case, by bringing each slat into contact with a slat positioned above, the ventilation opening can be closed, and intrusion of rain and the like from the downstream side of the ventilation opening can be prevented.

  Further, each slat can swing around the horizontal axis so that the lip can come into contact with a slat positioned above, and at least the tip of the lip is made of an elastic body. It may be configured.

  In this case, in a state where the slats are in contact with each other, the lip made of an elastic body is brought into contact with the upper slat so that the lip is elastically deformed and is in close contact with the upper slat. Since it acts as a sealing material between the slats, it is possible to more effectively prevent intrusion of rain and wind from the downstream side of the vent.

  Further, at least one of the slat body and the lip may have fine irregularities formed on the surface.

  In this case, the effect of collecting water droplets in the airflow is increased, and the water droplet collection efficiency is improved.

  Moreover, you may have the cooling device which cools at least any one of the said slat main body and a lip.

In this case, since at least one of the slat body and the lip is cooled by the cooling device, the water vapor contained in the airflow in contact with the slat body and the lip aggregates to form water droplets.
Thereby, not only water droplets in the airflow but also water vapor can be collected, and the water recovery efficiency is improved.

In the mobile weather experience device configured in this way, a ventilation device is provided on the downstream side of the air flow generated by the air blower in the experience room, so when the wind storm is produced by the air blower, the air blower is generated. The generated airflow does not accumulate in the experience room, but is quickly discharged out of the experience room through the vent.
As described above, in this mobile weather experience device, a smooth air flow from the blower to the vent is formed in the experience room, so that the burden on the blower can be reduced compared to a case where no vent is provided. Thereby, in this mobile weather experience apparatus, a smaller thing can be used as an air blower.

Furthermore, the moisture recovery device according to any one of claims 1 to 7 is provided at the ventilation port, and the amount of moisture discharged through the ventilation port when the rain is produced by the watering device is suppressed as much as possible. Therefore, the collection efficiency of the water sprayed by the watering device is high.
For this reason, in this mobile meteorological experience device, compared with the case where no water recovery device is provided, the water storage device is used to make the operation time of the watering device longer or to store the water used by the watering device. Smaller equipment can be used.

According to the moisture recovery apparatus of the present invention, it is possible to effectively recover water droplets in the airflow passing through the ventilation port while minimizing a decrease in the flow rate of the airflow passing through the ventilation port.
Further, since the structure of each slat is simple, the moisture recovery device can be small and light, and the manufacturing cost can be reduced.
And since there is little resistance with respect to the airflow which passes a ventilation opening, the noise which arises by passage of an airflow is also few.

In the mobile weather experience apparatus according to the present invention, it is possible to effectively collect water droplets in the airflow passing through the ventilation opening while minimizing a decrease in the flow rate of the airflow.
In this mobile weather experience device, a smaller air blower can be used.
Furthermore, in this mobile meteorological experience device, the collection efficiency of the water sprayed by the watering device is high, so that the operating time of the watering device can be made longer, or the water storage for storing the water used by the watering device.

Further, the moisture recovery device 31 is provided with a synchronization device (not shown) that synchronizes the swing of each slat 33 around the horizontal axis, and this synchronization device is operated manually or by a drive device. Thus, the directions of all the slats 33 can be changed in synchronization.
Here, the slat 33 located at the uppermost part swings around the horizontal axis so that the lip 37 can be brought into contact with the upper side of the frame 17. By swinging around the horizontal axis, the upstream end 36 b (that is, the lower end) can be brought into contact with the lower side of the frame 17.

Each slat main body 36 is provided over almost the entire width of the frame 32, and as shown in FIG. 4, the upstream end 36b and the downstream end 36a of the vent hole 17 are chamfered in a curved shape. It has a flat plate shape.

  The lip 37 is provided so as to be inclined so as to approach the upper end side of the slat main body 36 from the connecting part side to the slat main body 36 toward the tip. Further, at least the tip of the lip 37 is made of an elastic body such as rubber.

  Further, at least one of the slat main body 36 and the lip 37 has fine irregularities formed on the surface thereof. This unevenness is obtained, for example, by applying a satin finish to the slat body 36 and the lip 37. In the present embodiment, although not shown, irregularities are formed on both surfaces of the slat main body 36 and the lip 37.

The mobile weather experience device 1 configured in this way produces a storm in the experience room 3 by operating the air blower 4 and produces rain in the experience room 3 by operating the watering device 5.
Here, in this mobile meteorological experience apparatus 1, when operating the blower 4, the direction around the horizontal axis of each slat 33 of the moisture recovery device 31 provided at the ventilation port 17 is adjusted, 3 (a), gaps are formed between the respective slats 33, between the uppermost slat 33 and the upper side of the frame 32, and between the lowermost slat 33 and the lower side of the frame 32. Then, the ventilation opening 17 is opened.

In this mobile weather experience device 1, the ventilation port 17 is provided on the downstream side of the airflow generated by the air blower 4 in the experience room 3, so that when the air blower 4 produces a storm, The generated airflow does not stay in the experience room, but is quickly discharged out of the experience room 3 through the vent 17.
Thus, in this mobile weather experience device 1, since a smooth air flow from the blower 4 toward the vent 17 is formed in the experience room 3, the blower 4 is compared to the case where the vent 17 is not provided. Less burden. Thereby, in this mobile weather experience apparatus 1, a smaller thing can be used as the air blower 4.

On the other hand, in this mobile weather experience device 1, when the blower 4 and the watering device 5 are operated at the same time, the slat main body 36 constituting each slat 33 of the moisture recovery device 31 is an upstream end. It is made to incline with respect to a horizontal surface so that the edge part 36a of the downstream side may be located upwards with respect to 36b. Thereby, moisture is recovered from the airflow passing through the ventilation port 17.
Hereinafter, the operation of the moisture recovery apparatus 31 will be specifically described.

The airflow that has flowed into the ventilation port 17 passes through the gaps between the slats 33 of the moisture recovery device 31 and flows into the downstream side of the ventilation port 17.
The slat main body 36 constituting each slat 33 is provided to be inclined with respect to the horizontal plane so that the downstream end 36a is positioned above the upstream end 36b. The airflow that has flowed into the collecting device hits the upper surface of the slat body 36 of each slat 33, and the direction of the flow is changed to a direction that rises along the top surface. For this reason, the water droplets contained in the airflow hit the slat main body 36 by the inertial force and adhere to the slat main body 36.
Then, the air flow rising along the upper surface of the slat main body 36 hits the lip 37 protruding from the upper surface of the slat main body 36, and the direction of the flow is changed to a direction around the lip 37. For this reason, the water droplets contained in the airflow hit the lip 37 by the inertial force and adhere to the lip 37.
Here, since the wing plate main body 36 and the lip 37 have fine irregularities formed on their surfaces, the effect of collecting water droplets in the airflow is high, and the water droplet collection efficiency is high.

The water droplets adhering to the slat main body 36 and the lip 37 flow down to the upstream end 36b of the slat main body 36 through the lip 37 and the slat main body 36 by the action of gravity, and are upstream of the vent hole 17, that is, Fall inside the experience room 3.
For this reason, in this mobile meteorological experience device 1, the amount of water discharged through the air vent 17 can be suppressed as much as possible. Therefore, the efficiency of collecting the water sprayed by the water sprinkler 5 is high, and the water collector 31 is not provided. In comparison, the operation time of the watering device 5 can be made longer, or a smaller water storage tank 21 for storing the water used by the watering device 5 can be used.

Further, as described above, in this moisture recovery device 31, since the water droplets in the airflow are collected by changing the direction of the airflow passing through the ventilation port 17, there is little resistance to the airflow passing through the ventilation port 17, and Water droplets in the airflow passing through the ventilation port 17 can be effectively recovered while minimizing a decrease in the flow rate of the airflow passing through the port 17.
In the present embodiment, the lip 37 is provided to be inclined so as to approach the downstream end portion 36a side from the connecting portion side with the slat body 36 toward the tip. That is, since the lip 37 is inclined to the downstream side with respect to the airflow flowing along the upper surface of the slat main body 36, there is little resistance to the airflow passing through the ventilation port 17.
Thereby, in this mobile weather experience apparatus 1, the burden of the air blower 4 can be reduced, and the noise generated by the passage of the airflow is also small.

  And since the structure of each slat 33 is simple, the water | moisture-content collection | recovery apparatus 31 may be small and lightweight, and the manufacturing cost may be low.

Further, in the moisture recovery device 31, by adjusting the direction of each slat 33 around the horizontal axis, the interval between the slats 33 and the inclination angle of the slat body 36 can be adjusted.
For example, by increasing the inclination angle of the slat main body 36 with respect to the horizontal plane, the change angle of the direction of the air flow by the slat main body 36 is increased, and water droplets contained in the air current passing through the ventilation port 17 are more effectively collected. can do.
Further, by reducing the inclination angle of the slat main body 36 with respect to the horizontal plane, the resistance to the airflow passing through the ventilation port 17 is reduced.

Here, in this mobile meteorological experience device 1, when the blower 4 is not operated, the direction of each blade 33 around the horizontal axis is changed, as shown in FIG. By closing the ventilation port 17 by 33, it is possible to prevent intrusion of rain wind or the like from the downstream side of the ventilation port 17.
Furthermore, since the lip 37 of each slat 33 is formed of an elastic body at the tip, the lip 37 made of an elastic body is placed on the upper slat 33 or the frame 32 when the slats 33 are in contact with each other. By bringing the lip 37 into contact with the upper side, the lip 37 is elastically deformed and is brought into close contact with the upper slat 33 or the frame 32, and acts as a sealing material between the slats 33. Intrusion of rain and wind from the side can be prevented more effectively.
