Japanese Patent No. 2884510

  By the way, the thing of the said patent document 1 is only what a person puts an umbrella in an experience room, attaches rain gear, and gives a rain experience, and does not make a driver of a car experience a rain experience in a car.

  Therefore, if the experience room of the rain experience device of Patent Document 1 is expanded to make it a large facility where a real car can enter and exit, it will be possible for the driver to experience rain in the car. In each experience, a real car must be brought into and out of the experience room, which is troublesome to handle. In addition, the overall structure of the apparatus becomes large and complicated, and costs increase. Moreover, even if it is possible to experience rain from the inside of a stopped vehicle, it is difficult to experience a realistic rain in the vehicle while driving.

  The present invention has been proposed in view of the above, and allows the driver to have a realistic rain experience by resolving various rain situations and strengths assuming vehicle driving conditions while solving the above problems. It is an object of the present invention to provide a rain experience device having a relatively simple structure and a compact structure that enables accurate determination of the amount of rainfall in a vehicle during actual heavy rain driving.

In order to achieve the above object, the invention of claim 1 has a housing that forms an experience room in which an experiencer can enter and exit, and a plurality of types of fountain nozzles having different nozzle diameters. A spraying device capable of spraying downward, and a ceiling part of the experience room below the spraying device is arranged, and innumerable water droplets sprayed by the spraying device are applied and accumulated and dropped as raindrops. In the rain experience apparatus comprising a horizontal louver and a blower that blows downward into the experience room through the louver from above the spray device so as to urge raindrops dripping from the louver downward, An automobile model on which an experienced person can get on and off, and the front windshield of the automobile model, the raindrops from the louver are sprayed on the windshield below the louver. A pseudo running wind generating means for blowing air toward the windshield from the front side of the lath, viewer in a motor vehicle model and the front road display unit viewable is provided through the front glass, further said spray device and louver Is provided with guide means for guiding and guiding the water droplets and the flow of the air blown from the blower so that the spray region of the water droplets sprayed from the spraying device to the louver can be expanded. It is characterized by.

  According to a second aspect of the present invention, in addition to the feature of the first aspect of the invention, the simulated running wind generating means is disposed on a wall facing the windshield of the experience room, so that a frontal collision with the windshield. First air flow generating means for generating an air flow to be generated, and second air flow generating means disposed on the inner wall for generating an air flow blowing from the lower side along the front surface of the windshield. It is characterized by that.

Further, the invention of claim 3 is characterized in that, in addition to the features of the invention of claim 1 or 2 , the guide means are arranged concentrically with respect to each other about a vertical axis extending substantially directly below the water spray portion of the spray device. A plurality of circular louvers having different diameters arranged at intervals in the radial direction are provided, and an inclination angle of each louver with respect to the vertical axis is set to be larger as the louver has a larger diameter.

As described above, according to the invention of each claim, a spraying device having a plurality of types of fountain nozzles having different nozzle diameters and capable of spraying water downward from above into the experience room, and below the spraying device The horizontal louver is arranged so as to constitute the ceiling part of the experience room and accumulates and drops as raindrops by applying countless water droplets sprayed by the spraying device, and the raindrops dripping from the louvers are biased downward. Therefore, in the rain experience device having a blower that blows downward into the experience room through the louver from above the spray device, the experience person enters the car model in the experience room, and the simulated running wind generating means is located below the louver. By blowing simulated wind from the front side of the glass toward the windshield, dripping raindrops from the louver are blown against the windshield of the car model. As a result, it is possible to reproduce various rain conditions and strengths assuming the driving state of the vehicle, and to allow the experience person, that is, the driver, to have a realistic rain experience. It will be possible to make an accurate judgment of rainfall at times. Moreover, in use, the experiencer only has to get on and off the indoor car model, and there is no need to bring a real car into and out of the experience room, so it is easy to handle and the structure of the experience room is simplified and miniaturized as much as possible Can contribute to cost savings. Further, in order to reproduce the rain condition when the vehicle is traveling, it is necessary to allow more raindrops to fall on the windshield than when the vehicle is not traveling. In particular, in the present invention, it is provided between the spray device and the louver. The guide means can expand the spray diffusion area of the fine water droplets sprayed from the spray device to the louver, so it is efficient to collect more raindrops from the louver while minimizing the number of spray devices and blowers and increasing the capacity. Since it can be dripped well and a sufficient amount of rainfall can be secured, it is possible to accurately reproduce the rainfall situation when the vehicle is traveling at as low a cost as possible.

  In particular, according to the invention of claim 2, the air flow generated by the first air flow generating means and colliding frontally with the windshield, and the air flow generated by the second air flow generating means and descending along the front surface of the windshield. The simulated airflow is generated by the air flow that blows up from the side, so that the wind on the windshield (and raindrops from the louver) in the vehicle running state is more realistically reproduced. Therefore, it is possible to experience the rain conditions during traveling more faithfully.

In particular, according to the invention of claim 3 , the guide means are arranged in a concentric manner around a vertical axis extending substantially directly below the water spraying portion of the spraying device, and are arranged with a radial interval therebetween. Since the louver has a larger inclination angle with respect to the vertical axis, the guide means has a relatively simple louver structure, and the spray device has a relatively simple louver structure. The fine water droplets sprayed from the water spraying section and the air flow ejected from the blower can be guided smoothly and smoothly to the peripheral area of the water spraying section of the spraying device. This effectively enlarges the spray diffusion area to the louver.

  The housing H includes a box-shaped housing main body Hm having an open upper surface, and a roof Hr that covers the open upper surface of the housing main body Hm and is detachably attached to the housing H. On the inner surface of the roof Hr, the louver L serving as the ceiling portion of the experience room R and the support frame 2 for supporting the spray device Je and the blower B above the louver L are fixed. A plurality of blowers B that are parallel to each other in the longitudinal direction of the housing H and capable of blowing downward are mounted on the upper portion of the support frame 2, and the water supply of the spraying device Je is disposed on the lower portion of the support frame 2. The piping system is fixedly supported.

In the illustrated example, the water supply piping system of the spraying device Je is composed of four systems of water supply pipes 4 ₁ to ₄ 4 connected in parallel to the water supply source. Among these, the first water supply pipe 4 ₁ having the first nozzle N ₁ having the smallest diameter, the second water supply pipe 4 ₂ having the second nozzle N ₂ having the next largest diameter, and the third nozzle N ₃ having the next largest diameter. and the third water supply pipe 4 ₃ having a fog nozzle N ₀ is first of each of the downstream side is fixed along the adventure hall longitudinally on both left and right sides of the support frame 2 and bifurcated, and the maximum diameter A fourth water supply pipe 4 ₄ having 4 nozzles N ₄ and a mist nozzle N ₀ ′ is fixed to the left and right center of the support frame 2 along the longitudinal direction of the experience room.

Thus, a plurality of disc-like nozzle mounting frames A _{1 to} A ₉ are fixed to the support frame 2 at intervals in the left-right direction and the longitudinal direction of the experience room R, and a plurality of nozzle mountings on the left and right sides thereof are fixed. In the frames A _{1 to} A ₃ and A _{7 to} A ₉ , the nozzles N _{1 to} N ₃ and N _{0 of the first} to _third water supply pipes 4 ₁ to 4 ₃ are respectively arranged in a concentrated manner, and a plurality of right and left central parts are arranged. the nozzle mounting frame a ₄ to a _6, the fourth water supply pipe 4 ₄ each nozzle N ₄ of, N ₀ 'is concentrated deployed respectively. Each of the nozzles N _{1 to} N ₄ , N ₀ , N ₀ ′ incorporates an electromagnetic opening / closing valve (not shown) that can open and close each nozzle.

  The louver L has a plurality of strip-like vertical frames La that are linearly arranged in the front-rear direction at equal intervals in the left-right direction of the experience room R, and vertically arranged in the front-rear direction of the experience room R. A plurality of strip-like horizontal frames Lb, which extend in a straight line in the left-right direction at equal intervals and are vertically arranged, intersect and join in a lattice shape.

  Further, between the spray device Je and the louver L, the water and the flow of air blown from the blower B are provided so that the spray region of the water sprayed from the spray device Je to the louver L can be expanded. Guide means G for guiding and guiding is disposed, and the guide means G is suspended integrally with the support frame 2.

The guide means G is a vertical axis that passes through a centrally deployed area of the nozzles N _{1 to} N ₄ and N ₀ as a water spray portion of the spray device Je (that is, a substantially central portion of the nozzle mounting frames A _{1 to} A ₉ ). A plurality of circular louvers 3 having different diameters arranged concentrically around each other and arranged at intervals in the radial direction, and a connecting frame extending radially to integrally connect the circular louvers 3. 7 and the inclination angle of each louver 3 with respect to the vertical axis is set so as to increase as the louver 3 has a larger diameter.

  The housing body Hm has a rectangular parallelepiped shape having left and right side walls Hml and Hmr extending along the longitudinal direction thereof and front and rear walls Hmf and Hmb before connecting the left and right side walls Hml and Hmr. The left side wall Hml, which is formed and particularly viewed from the outside audience, is made of a transparent body so that the inside of the experience room R can be seen through. In addition, in the illustrated example, the left side wall Hml is composed of a plurality of transparent plates that can be folded in a folding screen, and by moving some of the transparent plates toward the front and rear side, the left side of the experience room R (from the outside audience) The front (viewing) is greatly open so that the experiencer can easily go in and out.

  The vehicle model M is installed and fixed in the experience room R from the center to the rear side. In the illustrated example, the vehicle model M is a vehicle with a relatively small vehicle body protruding forward from the windshield Fg, such as a small truck. Only the front half of the vehicle body including the driver's seat of the one-box car is used, so that the vehicle model M can be installed without difficulty while ensuring a sufficient effective volume in the experience room R. In addition, the front surface of the car model M is arranged slightly inclined to the front left of the experience room R, so that a person outside the experience room R can rain on the windshield Fg of the car model M through the transparent left wall Hml. You can observe the state of hitting well. The car model M includes a pair of left and right doors Ma for people to enter and exit, as in a normal car.

  Further, the front wall Hmf of the housing body Hm is composed of an outer wall 50 and an inner wall 51 that faces the outer wall 50 with a space therebetween, and an inner surface of the inner wall 51 facing the experience room R is an automobile model. A forward road display unit 1 representing the scenery is attached so that a person in M can see a scenery including the forward road through the windshield Fg.

  Further, in the illustrated example, the simulated traveling wind generating means W is disposed on a wall of the experience room R facing the windshield Fg (that is, the front wall Hmf of the housing main body Hm), and collides frontward with the windshield Fg. First air flow generating means W1 for generating an air flow, and second air flow generating means W2 disposed on the inner wall for generating an air flow that blows from the lower side along the front surface of the windshield Fg. Next, the configuration will be described.

  That is, a blower chamber 52 is defined between the outer wall 50 and the inner wall 51. The blower chamber 52 includes a pair of left and right first blowers W1 as a first air flow generating means and a second air. A pair of left and right second blowers W2 as flow generating means are housed and installed, and each of the blowers W1, W2 is driven by an electric motor. The pair of left and right first blowers W1 are located in the upper part of the blower chamber 52, and each air outlet W1a has a louver that rectifies the blown air and faces slightly downward toward the windshield Fg of the automobile model Mv. Thus, the blown air flow collides with the windshield Fg from the front.

  The pair of left and right second blowers W2 as the second air flow generating means are located in the lower part of the blower chamber 52, and each air outlet W2a includes a louver that rectifies the blown air, and is an automobile model Mv. It opens obliquely downward toward the immediately preceding road surface (the floor board f of the experience room R), so that the jet air flow reflects the road surface, along the front surface of the automobile model M (the windshield Fg) It comes to blow up from the side. The blown air flows of the blowers W1 and W2 act like a running wind on the automobile model M in a stationary state, and can produce a virtual running state of the model M.

  Thus, by controlling the energization of the first and second blowers W1 and W2, the wind speed or pressure of the air ejected from the blowers W1 and W2 can be adjusted stepwise or continuously. By adjusting the wind speed or wind pressure of the simulated running wind received from the front, the assumed vehicle speed in the virtual running state can be arbitrarily set (for example, 50 km / h, 70 km / h, 90 km / h, 110 km / h). is there.

  Further, the housing H is provided with a waterproof speaker for use in the presentation or guidance of the raining experience, and an audio device (none of which is shown) for outputting sound to the speaker.

  In addition, on the inner surface facing the experience room R of the right side wall Hmr of the housing body Hm, a landscape 1 'on the side of the road is drawn, and the estimated rainfall and the estimated vehicle speed during the experience are displayed on the upper part of the inner surface. A display panel 10 such as a liquid crystal panel is provided.

In the lower part of the housing H (that is, under the floor of the experience room R), a plurality of water storage tanks T for storing water used during the operation of the rain experience apparatus A and the water in the tanks T are sucked and sprayed. An electric water supply pump P that can be pumped to each of the fountain nozzles N _{1 to} N ₄ and N ₀ of the apparatus Je and a pump motor Mp that is linked to the water supply pump P and can drive the pump are installed. .

A filter 16 is interposed in the discharge flow path 9 of the water supply pump P, and the discharge flow path 9 on the downstream side of the filter 16 communicates with the first and second water supply pipes 4 ₁ and 4 ₂ , respectively. a second connecting flow channel 6 _and 62, and the third connecting flow path 6 ₃ and mist passage 6 ₀ communicating in parallel with each other in the third water supply pipe 4 _3, the fourth water supply pipe 4 ₄ It branches into a fourth connection flow path 6 ₄ and a fog flow path 6 ₀ ′ communicating in parallel with each other. And each connecting channel ₆₁ through _4, 6 _0, 6 ₀ ', the pressure reducing valve V ₁ ~V _4, V _0, V _0' and the check valve E ₁ to E _4, E _0, and E ₀ ' Are inserted sequentially from the upstream side. The pressure reducing valves V _{1 to} V ₄ , V ₀ , and V ₀ ′ use the water pressure on the downstream side thereof (therefore, the injection pressures of the corresponding nozzles N _{1 to} N ₄ , N ₀ , N ₀ ′) of the water supply pump P. It works to maintain an appropriate pressure regardless of fluctuations in discharge pressure. Further, the check valves E _{1 to} E ₄ , E ₀ and E ₀ ′ prevent the reverse flow of water from the nozzles N _{1 to} N ₄ , N ₀ and N ₀ ′ to the water supply pump P side.

An intermediate portion of the connecting channel ₆₁ through ₆ extends vertically along the pipe chamber 54 adjacent to the blower chamber 52, respectively connected to the water supply pipe ₄₁ to the _fourth base end at the upper end corresponding Is done. One end of a short circuit 18 with a bypass cock 17 is connected to the discharge flow path 9, and the other end of the short circuit 18 communicates with the water storage tank T. The bypass cock 17 is normally closed, and is temporarily opened when the water supply pump P and the air in the pipe are vented or when the pump P is operated for no load for a long period of time.

Thus, in the operation state of the water supply pump P (that is, the energization state of the pump motor Mp), the built-in electromagnetic valve of the first fountain nozzle N ₁ is opened and water is sprayed only from the nozzle N _1. When the blower B is operated at the first air flow stage, the internal electromagnetic valve of the second fountain nozzle N ₂ is opened so as to correspond to the rainfall intensity of 10 mm / h, and only from the nozzle N _2. When each blower B operates in a second air flow stage that is stronger than the first air flow stage in a state where water is sprayed, a third fountain nozzle N is further provided so as to correspond to a rainfall intensity of 20 mm / h. _{When the} blower B is operated in a third air volume step stronger than the second air flow step with water being sprayed from only the nozzle N ₃ by opening the built-in solenoid valve _3, the rainfall amount is 50 mm / to correspond to the rainfall intensity of h, furthermore built fourth fountain nozzle N ₄ Rainfall rainfall 100 mm / h in the case of solenoid valve is opened by the respective blowers B in a state where water is sprayed only from the nozzle N ₄ operates in stronger than the third flow rate stages fourth flow rate stage The nozzle diameters of the fountain nozzles N _{1 to} N ₄ and the air volume stages of the blower B are set so as to correspond to the strength. Note that 'when opening the solenoid valve. Mist nozzle N ₀ or N _0' fog nozzle N ₀ or N ₀ and is able to spray from together ultrafine water droplets such as fog.

  The floor surface of the experience room R is formed of a horizontal floor plate f having a large number of water-permeable holes (for example, a cocoon board), and a base surface formed with a space immediately below the floor plate f has a drain. A mouth 11 and a guide slope 12 that guides and drains the wastewater toward the drain port 11 are provided. Then, the water that has fallen on the floor board f along with the operation of the rain experience apparatus A falls to the guiding slope 12 through the water transmission holes of the floor board f, and is collected at the drain port 11 by the slope 12 to store the water immediately below it. It is collected in the tank T.

  A control panel C that can be arbitrarily operated from the outside is installed at a suitable place on the outer wall of the housing H. The control panel C includes an operation unit for controlling on / off of energization to the pump motor Mp, and a plurality of rainfall amounts. Operation unit for selecting and switching between stages (10 mm / h, 20 mm / h, 50 mm / h, 100 mm / h in the illustrated example), operation unit of the audio device (not shown), first and second air flow generating means The first and second blowers W1 and W2 as the wind speed or wind pressure (and therefore the assumed vehicle speed of the automobile model M) are selected and switched in a plurality of stages (for example, 50 km / h, 70 km / h, 90 km / h, 110 km / h). An operation unit, other operation units, and a power switch are provided.

  Next, the operation of the embodiment will be described.

  First, the rainfall experience apparatus A is mounted on the vehicle V and transported to a desired location, and the housing H is placed on the ground or the like of the transport destination by dropping it with a crane or the like.

  In using the rain experience device A, first, the water storage tank T is filled with water, and the pump motor Mp is energized by operating the operation panel C (the power source is an external power source or a battery attached to the experience device or the transport vehicle as appropriate). Use) to start the operation of the water supply pump P. Then, the bypass cock 17 is opened to release air from the pump P and the piping until a predetermined pump pressure is obtained. When this air removal is completed, preparation is complete, and the experiencer enters the experience room R and gets into the car model M.

  The operation of the rain experience apparatus A has an “automatic effect mode” and a “manual effect mode”, and which mode is selected is operated by a mode selection button on the control panel C.

  For example, when the “automatic rendering mode” is selected and the start button is pressed, the control device including the microcomputer in the control panel C is assumed to have a plurality of stages of assumed rainfall based on a preset control program. (In the example shown, 10 mm / h, 20 mm / h, 50 mm / h, 100 mm / h) and a plurality of assumed vehicle speeds (for example, 50 km / h, 70 km / h, 90 km / h, 110 km / h) are appropriately combined. Operate related equipment at a predetermined timing.

In other words, the selection of the assumed rainfall is switched by selectively opening the built-in solenoid valves of the fountain nozzles N _{1 to} N ₄ according to each rainfall and spraying water downward from the corresponding nozzles N _{1 to} N _4. In this way, the air flow rate of the blower B is also switched stepwise in accordance with the spray timing of the fountain nozzles N _{1 to} N ₄ . In accordance with these switching timings, a not-shown speaker provides guidance (announcement) on the amount of rainfall currently in progress, and generates a rain sound or wind sound corresponding to the amount of rainfall to realistically indicate the rainfall situation according to the amount of rainfall. Produce. If water is selectively sprayed one by one from a plurality of types of fountain nozzles N _{1 to} N ₄ having different nozzle diameters as in this embodiment, these nozzles N ₁ , N ₂ , N ₃ , The rainfall can be switched in stages such as 10 mm / h, 20 mm / h, 50 mm / h, and 100 mm / h corresponding to the diameter of N ₄ respectively. If spraying is performed, it is possible to set a rainfall amount other than the above.

Thus, innumerable water droplets selectively sprayed from the fountain nozzles N _{1 to} N ₄ hit the louver L which is the ceiling of the experience room R, grow and accumulate as raindrops of sufficient size and have an appropriate interval. The louver L is naturally dropped from the lower ends of the strips 5 ₁ , 5 ₂ ,. Moreover, since the dripping raindrops are assisted downward by the wind from the blower B, the raindrops can be dropped intermittently at a sufficient descent speed even in the relatively small experience room R, and natural rain As close as possible. Since various types of fountain nozzles N _{1 to} N ₄ with different nozzle diameters are selectively used and the wind strength of the blower B is appropriately selected, various selections of the rainfall intensity can be switched. Various rainfall conditions according to the amount are reproduced as faithfully as possible.

  In addition, the selection switching of the assumed vehicle speed is performed by performing energization control to the first and second blowers W1 and W2 in accordance with each vehicle speed, and adjusting the wind speed or the wind pressure of the air blown from the blowers W1 and W2. The assumed vehicle speed (for example, 50 km / h, 70 km / h, 90 km / h, 110 km / h) in a virtual driving state can be varied by changing the wind speed or wind pressure of the simulated driving wind received from the front of the automobile model M. Set. In this way, the windshield Fg of the automobile model M hits the front windshield Fg from the front, so that it is possible to realistically reproduce how the rain hits the windshield Fg in the above-described rain and running conditions. The experience person in M can easily experience and learn what the field of view from the inside of the car is at each assumed vehicle speed and the assumed rainfall.

In addition, when the “manual effect mode” is selected, the respective operation units for selecting the rainfall amount and the vehicle speed on the control panel C are operated to select from a plurality of preset assumed rainfall amounts and the assumed vehicle speed. Turn on the selection button corresponding to the amount of rainfall and vehicle speed you want to experience. Accordingly, _one of the built-in solenoid valves of the fountain nozzles N _{1 to} N ₄ is opened according to the selected rainfall amount and vehicle speed, and water is sprayed downward from the corresponding nozzles N _{1 to} N ₄ and the blower The air flow at the corresponding air volume stage is started from B, and energization control is performed on the first and second blowers W1 and W2, and an air flow of wind speed or wind pressure corresponding to the assumed vehicle speed is ejected from the blower.

  Then, according to the selected rainfall and vehicle speed, the speaker Sp provides an announcement of the rainfall currently being executed (announcement) and makes a rain sound and wind sound corresponding to the rainfall and the vehicle speed to make the rainfall situation realistic. Produce. If a plurality of rainfall selection buttons are simultaneously turned on, it is possible to set a rainfall amount equal to the sum of the rainfall amounts corresponding to the simultaneously operated buttons. For example, a 20 mm / h selection button and a 50 mm / h selection button can be set. If the h selection button is pressed at the same time, the rainfall can be set to 70 mm / h.

Thus, in this embodiment, an experienced person enters the automobile model M in the experience room R, adjusts the spray amount of water droplets from a plurality of types of fountain nozzles N _{1 to} N _{4 having} different nozzle diameters, and winds of the blower B By appropriately selecting the strength of the rain, it is possible to reproduce the various rain conditions according to the amount of rainfall by making rain from the louver L artificially, and in addition, the first and second blowers W1, W2 By adjusting the wind speed or wind pressure of the air ejected from the vehicle, the wind speed or wind pressure of the simulated running wind that the automobile model M receives from the front is adjusted, and dripping raindrops from the louver L on the windshield Fg in the virtual running state Can be sprayed vigorously. This makes it possible to realistically reproduce how rain hits the windshield Fg under the assumed rain / running conditions, and those who have experience in the car model M have a forward view from inside the car at each assumed vehicle speed / rainfall. You can easily experience and learn what it is like. Note that an outside audience can also realistically observe how the rain hits the vehicle in the above-described rain / running state.

  In this way, it is possible to realistically reproduce how the rain hits the front of the car when driving at various rainfalls and vehicle speeds, so that the driver can experience a realistic rain driving experience, so the driver can actually run heavy rain It will be possible to make accurate judgments such as rainfall. In addition, the user only needs to get on and off the indoor car model M, and there is no need to bring a real car into and out of the experience room R, so the handling is simple and the structure of the experience room R is as simple as possible. In addition, the size can be reduced.

  Particularly in this embodiment, an air flow generated from the first blower W and colliding frontward with the windshield Fg, and an air generated from the second blower W2 and blown from the lower side along the front surface to the windshield Fg. Since the simulated running wind is generated by the flow, it becomes possible to more realistically reproduce the condition of the running wind (and dripping raindrops from the louver L) on the windshield Fg in the vehicle running state. The rain experience during driving will be more faithful.

  Further, in order to reproduce the rain condition when the vehicle is traveling, it is necessary to efficiently drop a larger amount of raindrops on the windshield Fg than when the vehicle is not traveling, but in this embodiment, the spray device Je and the louver L In the meantime, the guide means G for guiding and guiding the water sprayed from the spray device Je and the flow of air blown from the blower B is disposed, so that the fine water droplets sprayed from the spray device Je are sprayed onto the louver L. The diffusion region can be effectively expanded, and therefore, a large amount of raindrops can be collected by the louver L and dripped efficiently from the louver L while suppressing the increase in the number of spray devices Je and blowers B and the increase in capacity. It is possible to secure a certain amount of rainfall.

  As mentioned above, although the Example of this invention was described, this invention is not limited to the Example, A various Example is possible within the scope of the present invention. For example, in the above-described embodiment, the vertical frame La and the horizontal frame Lb constituting the louver L are vertically arranged in a strip shape. However, in the present invention, the vertical frame and the horizontal frame of the louver L are placed on a horizontal plane. The middle part of each vertical frame and horizontal frame may be curved in a cross-sectional arc shape or bent in a cross-sectional shape, and the vertical frame It is also possible to omit one of the horizontal frames.

In the above embodiment, and when not sprayed from any fountain nozzles N ₁ to N _4, it can be sprayed mist ultrafine water droplets when sprayed from the first or second fountain nozzles N _1, N ₂ The mist nozzles N ₀ , N ₀ ′ are shown together with the mist nozzles N ₀ , N ₀ ′ and the corresponding flow paths 6 ₀ , 6 ₀ ′ (therefore, the flow paths thereof). The pressure reducing valves V ₀ , V ₀ ′ and check valves E ₀ , E ₀ ′) can be omitted.
