Summary of Invention
Technical Problem
[0004] In the booths, a doorway that allows access to the internal space is required for
the entrance and exit of workers and the carrying-in and carrying-out of goods. In
a case where a structure such as a door, a sliding door, or a curtain is provided
at the doorway, the access is complicated and the workability deteriorates. Thus,
it is considered that the doorway is simply an opening portion without such a structure.
However, in this case, the blocking from the external space is insufficient, and it
is difficult to perform air-conditioning control, for example, temperature control
and humidity control in the internal space. Additionally, there is a concern that
dust is mixed into the internal space from the opening portion, which lowers the cleanliness
of the internal space. In this way, in a case where the doorway of the booth is simply
the opening portion, various environmental conditions (temperature, humidity, cleanliness,
and the like) deteriorate.
[0005] An aspect of the present invention is to realize a booth that allow easy access to
an internal space without deteriorating environmental conditions.
Solution to Problem
[0006] In order to solve the above-mentioned problems, a booth according to the present
invention includes an ejecting unit as defined in claim 1. Further preferred embodiments
of the invention are defined in the dependent claims.
Advantageous Effects of Invention
[0007] According to the aspect of the present invention, it is possible to realize the booth
that allows easy access to the internal space without deteriorating the environmental
conditions.

Description of embodiments
[Embodiment 1]
[0009] Hereinafter, one embodiment of the present invention will be described in detail.
(Overall configuration of booth)
[0010] Fig. 1 is a view illustrating a schematic configuration of a booth 10 according to
Embodiment 1. Additionally, Fig. 2 is a view schematically illustrating a vertical
cross-section observed from the side of the booth 10. The booth 10 has an internal
space S partitioned from an external space formed by a ceiling portion 101, two side
wall portions 102, a front wall portion 103, and a rear wall portion 104, which are
partition members assembled on a floor 90 (not included in the components of the booth
10). The size of the internal space S is not limited to a specific value and can be,
for example, about 3 to 20 m in a depth direction, 3 to 20 m in a width direction,
and 2 to 5 m in a height direction.
[0011] An opening portion 105 is provided in a part of the front wall portion 103 in the
vicinity of the center thereof to constitute a doorway to the internal space S. The
size of the opening portion 105 is not limited to a specific value and can be, for
example, about 1 to 3 m in the width direction smaller than the width of the internal
space and about 2 to 5 m in the height direction smaller than the height of the internal
space S.
[0012] Additionally, the booth 10 includes an air conditioning device (air conditioning
unit) 150 outside the internal space S and performs the air-conditioning control of
the internal space S. The internal space S is a region for performing work in environments
of which the atmosphere is air-conditioning controlled, such as assembling of electronic
components and precision components, various kinds of work such experiments, and the
operations of process devices and precision machines, machine operations, and the
like. The air-conditioning control is specifically temperature control in Embodiment
1. However, the air-conditioning control is not limited to the temperature control
and may be, for example, humidity control or cleanliness control.
[0013] The partition members (ceiling portion 101, side wall portion 102, front wall portion
103, rear wall portion 104) may be made of any appropriate known materials that are
used as booth wall materials or ceiling materials such as vinyl curtains, heat-insulating
uninflammable panels, glass, acrylic plates, and metal plates. Additionally, in order
to maintain the structural strength, it is preferable that the partition members are
assembled by appropriately using frames, columns, beams, and the like.
[0014] The booth 10 is provided with an ejecting device (ej ecting unit) 120 for ejecting
air into the opening portion 105. As a specific attachment position of the ejecting
device 120, for example, the ejecting device 120 can be attached to a part of the
front wall portion 103 that is an end portion of the opening portion 105. Additionally,
a suction device (suction unit) 130 for suctioning air is attached to a position facing
the ejecting device 120 (for example, a part of the front wall portion 103 that is
an edge portion of the opening portion 105). The ejecting device 120 and the suction
device 130 are disposed outside the front wall portion 103 along a vertical line,
respectively, on the left and right sides of the opening portion 105. Additionally,
an air ejection port of the ejecting device 120 and an air suction port of the suction
device 130 are disposed so as to face each other. In addition, the booth 10 of Embodiment
1 is provided with one ejecting device 120 and one suction device 130. However, a
plurality of ejecting devices 120 may be configured to be installed side by side along
the edge portion of the opening portion 105 so as to play substantially the same role
as one large ejecting device. The same applies to the suction device.
(Temperature control of internal space)
[0015] An introduction port 111 for introducing temperature-controlled air into the internal
space S of the booth 10 is provided on a bottom surface of the ceiling portion 101.
The air controlled to a predetermined temperature is fed from the air conditioning
device 150 through a pipe 143 to the introduction port into the introduction port
111. The introduction port 111 releases a uniformized airflow (downflow) of which
a blowing direction is controlled downward to the internal space S. In Fig. 1, the
introduction port 111 is drawn as two members divided into left and right. However,
this is merely an example and may be constituted of a single member or two or more
of a plurality of members, and may be provided on substantially the entire surface
of the ceiling portion 101. Additionally, the introduction port 111 is attached to
the rear wall portion 104 as exemplified in Fig. 1 and does not have to have a shape
extending in the depth direction. For example, the introduction port 111 may be hung
from the ceiling portion 101 or embedded in the ceiling portion 101. Additionally,
it is preferable that the introduction port 111 is provided with a filter or a mesh
for removing dust and the like.
[0016] The air fed into the internal space S is drawn into a lead-out port 112 provided
at a lower part of the rear wall portion 104 and is recovered to the air conditioning
device 150 through a pipe 144 to the lead-out port. The shape of the lead-out port
112 may be a horizontally long rectangular shape as illustrated in Fig. 1 but other
shapes or any number of holes can be appropriately used. Here, the pipe may be, specifically,
a circular tubular member, an angular tubular member, a duct, or the like, and the
same applies to the following.
[0017] In this way, the air temperature-controlled by the air conditioning device 150 is
circulated, so that the internal space S of the booth 10 is controlled to a predetermined
temperature. The wind speed of the airflow blown out from the introduction port 111
is not limited to a specific value but it is desirable that the wind speed is as slow
as 0.1 to 1 m/s. This is because in a case where the wind speed is high, there is
a spot that is partially cooled by the airflow directly hitting the equipment and
furniture installed in the internal space S and there is a concern of causing a temperature
distribution. In addition, in the present application, the wind speed of the airflow
is defined by the wind speed (blow-out wind speed) directly below a blow-out port
such as the introduction port and the ejection port.
[0018] Additionally, it is not preferable in terms of temperature control that the outside
air directly flows into the internal space S. Thus, the internal space S is maintained
at a slightly positive pressure by the air conditioning device 150. For that reason,
air slightly flows out from the internal space S through the opening portion 105 and
the like (EA in Fig. 2). In order to compensate for the outflowing air and further
keep the internal space S at a positive pressure, the air conditioning device 150
takes in air from an outside air intake port 151, adjusts the temperature together
with the air recovered from the internal space S, and provides a required volume of
air to a required spot.
(Airflow control at opening portion)
[0019] Moreover, the characteristic airflow control in the opening portion 105 will be described
with reference to Figs. 3 and 4. Fig. 3 is a schematic view illustrating the ejecting
device 120 according to Embodiment 1. Fig. 4 is a view schematically illustrating
a horizontal cross-section of the booth 10.
[0020] Temperature-controlled air is supplied from the air conditioning device 150 through
a pipe 141 to the ejecting device to the ejecting device 120. The ejecting device
120 includes an outside ejection port 121 (first ejection port) and an inside ejection
port 122 (second ejection port) that are vertically elongated, respectively, and correspond
to the length of the opening portion 105 in the vertical direction. The outside ejection
port 121 and the inside ejection port 122 are parallel to each other. The outside
ejection port 121 is provided on a side farther from the internal space S than the
inside ejection port 122. The lengths of the outside ejection port 121 and the inside
ejection port 122 are not limited to a specific values and may be, for example, 2
to 5 m. Additionally, as described above, in a case where the plurality of ejecting
devices 120 are configured to be installed side by side along the edge portion of
the opening portion 105, the lengths of the outside ejection port 121 and the inside
ejection port 122 are not limited to specific value and may be, for example, about
0.5 to 2 m.
[0021] The outside ejection port 121 blows out an outside airflow 126 (first airflow) in
a horizontal direction parallel to a plane formed by the opening portion 105 (parallel
to the front wall portion 103). Here, the outside airflow 126 is a layered airflow
that covers the opening portion 105, that is, an air curtain. Additionally, the inside
ejection port 122 blows out an inside airflow 127 (second airflow) in the horizontal
direction parallel to the plane formed by the opening portion 105 (parallel to the
front wall portion 103). Here, the inside airflow 127 is a layered airflow covering
the opening portion 105, which is also an air curtain. The direction of the outside
airflow 126 and the direction of the inside airflow 127 are parallel to each other
and the same direction.
[0022] The inside airflow 127 is a weaker airflow than the outside airflow 126. Here, the
weaker airflow means that the wind speed is relatively low (slow). The preferable
wind speed of the outside airflow 126 is 4 to 8 m/s and may typically be 5 m/s. The
preferable wind speed of the inside airflow 127 is relatively lower than the wind
speed of the outside airflow 126 and is 3 to 6 m/s, and may typically be 4 m/s. Moreover,
by maintaining the internal pressure at a positive pressure, the wind speed can be
lowered. In that case, the preferable wind speed may be 3 to 6 m/s for the outside
airflow 126 and 2 to 4 m/s for the inside airflow 127. By reducing the wind speed,
the turbulence of the flow of air is reduced, and the effect of the present invention
of suppressing the influence of the disturbance on the internal space S can be further
exhibited.
[0023] In any case, the wind speeds of the outside airflow 126 and the inside airflow 127
are not limited to the above range and may appropriately have different values. However,
as described above, the outside airflow 126 needs to have a higher wind speed than
the inside airflow 127.
[0024] Additionally, more preferably, the wind speed of the inside airflow 127 is higher
than the wind speed of the airflow blown out from the introduction port 111 in the
internal space S.
[0025] The suction device 130 plays a role of suctioning air such that the outside airflow
126 and the inside airflow 127 do not disturb the flow of each as a layered airflow.
It is desirable that the suction device 130 has two vertically elongated suction ports
that correspond to the outside airflow 126 and the inside airflow 127, respectively.
However, the suction device 130 may have one vertically elongated suction port for
suctioning both the outside airflow 126 and the inside airflow 127. It is desirable
that the length of the vertically elongated suction port is almost the same as that
of the outside ejection port 121 or the inside ejection port 122 of the ejecting device
120. The air suctioned by the suction device 130 is fed through the pipe 142 directed
to the suction device into the air conditioning device 150.
[0026] Additionally, the wind speeds of the outside airflow 126 and the inside airflow 127
can be appropriately adjusted depending on the distance between the ejecting device
120 and the suction device 130. The distance between the ejecting device 120 and the
suction device 130 is specifically the distance between the outside ejection port
121 (first ejection port) in the ejecting device 120 and the suction port of the suction
device 130 for suctioning the outside airflow 126 and the inside ejection port 122
(second ejection port) in the ejecting device 120 and the suction port of the suction
device 130 for suctioning the inside airflow 127. The preferable wind speed of the
outside airflow 126 with respect to the distance between the ejecting device 120 and
the suction device 130 is 2.5 to 5.5 m/s per 1 meter of the distance between the ejecting
device 120 and the suction device 130 and may typically be 3.3 m/s. The preferable
wind speed of the inside airflow 127 with respect to the distance between the ejecting
device 120 and the suction device 130 is 2 to 4 m/s per 1 meter of the distance between
the ejecting device 120 and the suction device 130 and may typically be 2.7 m/S. Moreover,
in a case where the internal pressure is maintained at a positive pressure, the wind
speed may be 2 to 4 m/s for the outside airflow 126 and 1 to 3 m/s for the inside
airflow 127 per 1 meter of the distance between the ejecting device 120 and the suction
device 130. By reducing the wind speed, the turbulence of the flow of air is reduced,
and the effect of the present invention of suppressing the influence of the disturbance
on the internal space S can be further exhibited.
(Effects in Embodiment 1)
[0027] The followings are realized in the booth 10 according to Embodiment 1 by virtue of
the above configuration.
[0028] Since the opening portion 105 is included in a part of the front wall portion 103,
the entrance and exit of workers and the carrying-in and carrying-out of goods are
easy, and access to the internal space S is excellent. For that reason, the efficiency
of various kinds of work using the booth 10 is improved.
[0029] Generally, in a booth including such an opening portion, it is difficult to perform
the air-conditioning control of the internal space due to the inflow of outside air
and the outflow of air in the internal space. For example, in a case where the temperature
control is performed as the air-conditioning control, it is difficult to set the internal
space S to a predetermined uniform temperature due to the inflow of outside air (an
example of disturbance) of which the temperature control is insufficient. Additionally,
the inflow of wind (an example of disturbance) into the internal space also causes
the flow of air in the internal space to be disturbed. However, since the booth 10
is configured to form an airflow serving as the air curtain in the opening portion
105, the inflow of outside air and the outflow of air in the internal space can be
suppressed. That is, the air booth 10 works in the direction of blocking the inside
and outside.
[0030] Additionally, the booth 10 has a characteristic configuration in which the outside
airflow 126 (first airflow) and the inside airflow 127 (second airflow) are formed
at the opening portion 105, and the inside airflow 127 is weaker than the outside
airflow 126. The significance of such a characteristic configuration will be described
below.
[0031] The present inventors initially studied a configuration in which a single-layer airflow
(air curtain) is formed at the opening portion. Then, in a case where the wind speed
of the airflow was low, the effect of suppressing the inflow of outside air and the
outflow of air in the internal space was poor, and a targeted temperature control
in the internal space S could not be performed. More specifically, the targeted temperature
control here means that the distribution of temperature in the internal space S can
be controlled to be within ± 0.1 degrees with respect to a temperature target value.
[0032] Next, an attempt to increase the wind speed of the airflow was made in order to enhance
the effect of blocking the inside and outside. However, in a case where the wind speed
of the single-layer airflow was increased, the air in the internal space was drawn
in and accelerated, and the airflow entered the internal space. As a result, a spot
having a high wind speed was partially formed in the internal space, and the targeted
temperature control in the internal space could not be performed. This is because
the temperature distribution in the internal space S is disturbed because the spot
having a high wind speed is partially formed. Although various wind speeds were studied,
a targeted temperature distribution in the internal space could not be realized in
the single-layer airflow (air curtain).
[0033] Additionally, although the temperature distribution of the internal space S has been
described here, the humidity distribution is almost the same.
[0034] Additionally, it was also found that the adoption of a single-phase airflow does
not suitably prevent the mixing of dust. In a case where the wind speed of the single-layer
airflow is lowered, there is a concern that the prevention of mixing of dust into
the internal space S by virtue of the airflow may not work sufficiently. On the other
hand, in a case where the single-layer airflow is increased, dust may be involved
in the entering of the airflow into the above-described internal space S, and as a
result, there is a case where the dust is mixed into the internal space.
[0035] Thus, the present inventors have come up with the idea of forming a two-layer airflow
of an outside airflow 126 having a high wind speed and an inside airflow 127 having
a weaker wind speed than the outside airflow 126 at the opening portion 105, and have
completed the present invention. The outside airflow 126 having a high wind speed
plays a role of making the effect of blocking the inside and outside sufficient. That
is, the outside airflow 126 plays a role of suppressing the influence of the disturbance
on the internal space S. On the other hand, the relatively weak inside airflow 127
plays a role of suppressing the entering of the outside airflow 126 having a high
wind speed into the internal space S. Additionally, by adopting such a unique airflow
configuration and disposition, in the booth 10, the targeted temperature control and
humidity control in the internal space S can be realized, and dust can be suitably
prevented from being mixed into the internal space.
[0036] Moreover, the booth 10 includes a suction device 130 that is provided at the edge
portion of the opening portion 105 so as to face the ejecting device 120 and suctions
air. By virtue of the present configuration, disturbance of the outside airflow 126
(first airflow) and the inside airflow 127 (second airflow) even in the regions of
the opening portion 105 separated from the outside ejection port 121 and the inside
ejection port 122 is suppressed. Thus, the targeted temperature control, humidity
control, and prevention of mixing of dust in the internal space S can be suitably
realized.
[0037] Additionally, by making the directions of the outside airflow 126 (first airflow)
and the inside airflow 127 (second airflow) horizontal, the ejecting device 120 and
the suction device 130 can be longitudinally mounted on the left and right sides of
the opening portion 105. Thus, a booth including the ejecting device 120 and the suction
device 130 can be easily manufactured.
[0038] In the booth 10, the outside airflow 126 (first airflow) and the inside airflow 127
(second airflow) are formed by the air supplied from the air conditioning device 150.
By forming the outside airflow 126 and the inside airflow 127 with the air that is
air-conditioning controlled by the air conditioning device 150, the factors of disturbing
the control of the internal space S are suppressed, and the targeted air-conditioning
control in the internal space S is reliably realized.
[0039] The ejecting device 120 according to Embodiment 1 used in the booth 10 includes the
outside ejection port 121 (first ejection port) for forming the outside airflow 126
(first airflow) and the inside ejection port 122 (second ejection port) for forming
the inside airflow 127 (second airflow) weaker than the outside airflow 126. By applying
the ejecting device 120 having the present configuration to a booth including with
an opening portion, it is possible to realize a configuration in which the temperature
control of the internal space is made excellent while access to the internal space
is excellent.
[Embodiment 2]
[0040] Another embodiment of the present invention will be described below. In addition,
for convenience of description, the members having the same functions as the members
described in the above embodiment will be denoted by the same reference numerals,
and the description thereof will not be repeated.
[0041] Figs. 5A and 5B are views illustrating a schematic configuration of a booth 20 according
to Embodiment 2. Fig. 5A is a view schematically illustrating a cross-section in the
horizontal direction for illustrating the schematic configuration of the booth 20
according to Embodiment 2. Unlike the booth 10 according to Embodiment 1, the booth
20 does not include the suction device 130 and the pipe 142 to the suction device.
Additionally, unlike the booth 10, the ejecting devices 120 are included on both the
left and right edge portions of the opening portion 105. The pipe 141 to the ejecting
device for supplying air-conditioning controlled (temperature-controlled) air from
the air conditioning device 150 is connected to each of the ejecting devices 120.
[0042] The left and right ejecting devices 120 each form a two-layer airflow of an outside
airflow 226 (first airflow) having a high wind speed and an inside airflow 227 (second
airflow) weaker than the outside airflow 226. Thus, the outer shapes of the left and
right ejecting devices 120 are mirror-symmetrical to each other. In addition, the
direction of each airflow is the horizontal direction.
[0043] The preferable wind speed of the outside airflow 226 is 2 to 4 m/s and may typically
be 3 m/s. The preferable wind speed of the inside airflow 227 is relatively smaller
than the wind speed of the outside airflow 226 and is 1 to 3 m/s, and may typically
be 2 m/s . In any case, the wind speeds of the outside airflow 226 and the inside
airflow 227 are not limited to the above range and may be appropriately different
values. However, as described above, the outside airflow 226 needs to have a higher
wind speed than the inside airflow 227.
[0044] Additionally, the wind speeds of the outside airflow 226 and the inside airflow 227
can be appropriately adjusted depending on the distance between the outside ejection
ports 121 (first ejection ports) or between the inside ejection ports 122 (second
ejection ports) of the left and right ejecting devices 120. The preferable wind speed
of the outside airflow 226 with respect to the distance between the left and right
outside ejection ports 121 is 1 to 3 m/s per 1 meter of the distance between the left
and right outside ejection ports 121 and may typically be 2 m/s. The preferable wind
speed of the inside airflow 227 with respect to the distance between the left and
right inside ejection ports 122 is 0.5 to 2 m/s per 1 meter of the distance between
the left and right inside ejection ports 122 and may typically be 1.3 m/s.
[0045] In the booth 20 according to Embodiment 2, since air is supplied from the left and
right ejecting devices 120, the wind speeds of the outside airflow 226 and the inside
airflow 227 can be reduced as compared to a case where air is supplied from one side.
For that reason, the turbulence of the flow of air is reduced, and the effect of the
present invention of suppressing the influence of the disturbance on the internal
space S is further exhibited.
[0046] The other configurations are the same as those of the booth 10 according to Embodiment
1. Thus, in the booth 20, the same effects as in Embodiment 1 can be obtained except
for the effects of the suction device 130.
[0047] Additionally, in the booth 20, since the outside airflow 226 and the inside airflow
227 are formed from the left and right with respect to the opening portion 105, each
airflow (air curtain) easily covers the opening portion 105. Therefore, it is easy
to increase the width of the opening portion 105. On the other hand, since the airflows
from the left and right meet in the vicinity of a central portion of the opening portion
105 in the width direction, there is a concern that the airflows are easily disturbed.
Thus, the directions of the outside airflow 226 and the inside airflow 227 are substantially
parallel to the plane formed by the opening portion 105 (substantially parallel to
the front wall portion 103). However, it is preferable that the directions are slightly
outward so that the outside airflow 226 and the inside airflow 227 do not easily enter
the internal space S.
[0048] Fig. 5B is an explanatory view illustrating angles θi1 and θi2 of the inside airflow
227 with respect to the plane P formed by the opening portion 105. The angles θi1
and θi2 of the left and right inside airflows 227 are not particularly limited and
are preferably 0° to 45°. The lower limit value is, for example, 1° or more, 3° or
more, 5° or more, or 10° or more. Additionally, the upper limit value is, for example,
40° or less, 35° or less, or 30° or less. The angles θi1 and Θi2 of the left and right
inside airflows 227 may be the same angle or different angles.
[0049] Additionally, similarly, with respect to the outside airflow 226, angles θo1 and
θο2 of the left and right outside airflows 226 are not particularly limited and are
preferably 0° to 45°. The lower limit value is, for example, 1° or more, 3° or more,
5° or more, or 10° or more. Additionally, the upper limit value is, for example, 40°
or less, 35° or less, or 30° or less. The angles θo1 and θο2 of the left and right
outside airflows 226 may be the same angle or different angles.
[0050] Moreover, the angle of the inside airflow 227 and the angle of the outside airflow
226 may be the same angle or different angles.
[0051] In addition, the angles (θi1, θi2, θo1, θo2) may be variably controlled depending
on conditions such as the temperature and humidity of the internal space S and the
external space. Accordingly, for example, even in a case where there is a change in
the external environment or the like, the influence of the disturbance on the internal
space S can be more excellently suppressed. As a specific example, for example, in
a case where the air temperature in the external space rises, the outside airflow
226 and the inside airflow 227 are warmed by the radiant heat generated from the floor
or the like, and the outside airflow or the inside airflow easily enters the internal
space S. In such a case, the influence of the disturbance can be suppressed by making
the angle further outward.
[Embodiment 3]
[0052] Fig. 6 is a view schematically illustrating a cross-section in a vertical plane for
illustrating a schematic configuration of a booth 30 according to Embodiment 3. Unlike
the booth 10 according to Embodiment 1, the booth 30 does not include the suction
device 130 and the pipe 142 to the suction device. Additionally, unlike the booth
10, a transversely mounted ejecting device 320 is provided at an upper edge portion
of the opening portion 105. The pipe 141 to the ejecting device for supplying air-conditioning
controlled (temperature-controlled) air from the air conditioning device 150 is connected
to the ejecting device 320.
[0053] The ejecting device 320 forms a two-layer airflow of an outside airflow 326 (first
airflow) having a high wind speed and an inside airflow 327 (second airflow) weaker
than the outside airflow 326. In addition, the direction of each airflow is downward
in the vertical direction.
[0054] The other configurations are the same as those of the booth 10 according to Embodiment
1. Thus, also in the booth 30, the same effects as in Embodiment 1 can be obtained
except for the effects of the suction device 130.
[0055] In the booth 30, the outside airflow 326 and the inside airflow 327 are formed from
above the opening portion 105. Thus, the opening portion 105 is less likely to be
limited in the width direction thereof, and it is easy to increase the width of the
opening portion 105. Additionally, a plurality of the ejecting devices 320 may be
configured to be installed side by side along the upper edge portion of the opening
portion 105.
[0056] Similar to the ejecting device 120 according to Embodiment 1, the ejecting device
320 according to Embodiment 3 used in the booth 30 also includes an outside ejection
port (first ejection port) for forming the outside airflow 326 (first airflow) and
an inside ejection port (second ejection port) for forming an inside airflow 327 (second
airflow) weaker than the outside airflow 326. By applying the ejecting device 320
having the present configuration to a booth including with an opening portion, it
is possible to realize a configuration in which the temperature control of the internal
space is made excellent while access to the internal space is excellent.
[Embodiment 4]
[0057] Fig. 7 is a view schematically illustrating a cross-section in a vertical plane for
illustrating a schematic configuration of a booth 31 according to Embodiment 4. The
booth 31 according to Embodiment 4 is a booth in which a suction device 330 disposed
so as to face the ejecting device 320 and a pipe to the suction device, which is connected
to the suction device 330, are added to the booth 30 according to Embodiment 3. In
Embodiment 4, the suction device 330 is disposed below the opening portion 105. The
suction device 330 can be disposed at a position higher than the floor surface 90.
In this case, the construction of the booth becomes easy. Alternatively, the suction
device can be disposed at a position lower than the floor surface 90. In this case,
access to the internal space is not hindered. Also in the booth according to Embodiment
4, the same effects as those of the above embodiment can be obtained.
[Embodiment 5]
[0058] Fig. 8 is a view schematically illustrating a cross-section in a vertical plane for
illustrating a schematic configuration of a booth 11 according to Embodiment 5. The
booth 11 according to Embodiment 5 is a booth in which the suction device 130 and
the pipe 142 to the suction device are omitted from the booth 10 according to Embodiment
1. Also in the booth 11 according to Embodiment 5, the same effects as those of the
booth 10 according to Embodiment 1 can be obtained except for the effects of the suction
device 130.
[Embodiment 6]
[0059] Fig. 9 is a view schematically illustrating a front view of the booth 12 according
to Embodiment 6. A booth 60 according to Embodiment 6 is a booth in which an upper
cover 160 that covers an upper part of the opening portion 105 is provided in the
booth 10 according to Embodiment 1, and the other configurations are the same.
[0060] In a case where the temperature of the air supplied from the ejecting device 120
is lower than that of the external space, the air supplied from the ejecting device
120 is heavier than the air of the external space. Therefore, a tendency is observed
that the air supplied from the ejecting device 120 flow downward. For that reason,
there is a concern that outside air is likely to flow in from the upper part of the
opening portion 105. According to the booth 12 according to Embodiment 6, since the
upper cover 160 covering the upper part of the opening portion 105 is provided, the
inflow of outside air from the upper part of the opening portion 105 can be suppressed.
[0061] Additionally, the air supplied from the ejecting device 120 is diffused up, down,
left, and right. Thus, in the booth 10 according to Embodiment 1, a part of the air
in the upper part of the opening portion 105 is dispersed in an upward direction without
facing the suction device 130. However, by providing the upper cover 160, the air
supplied from the ejecting device 120 can be straightened in the direction of the
suction device 130.
[0062] The shape of the upper cover 160 is not particularly limited and is, for example,
a plate member installed in the horizontal direction. From the viewpoint of straightening
the flow of air supplied from the ejecting device 120, the surface of the upper cover
160 on the opening portion 105 side is preferably formed in a direction in which the
air supplied from the ejecting device 120 flows.
[Embodiment 7]
[0063] Fig. 10 is a view schematically illustrating a front view of a booth 21 according
to Embodiment 7. The booth 21 according to Embodiment 7 is a booth in which the upper
cover 160 that covers the upper part of the opening portion 105 is provided in the
booth 20 according to Embodiment 2, and the other configurations are the same. Similar
to Embodiment 6, by providing the upper cover 160, the inflow of outside air from
the upper part of the opening portion 105 can be suppressed.
[0064] Additionally, the air supplied from the ejecting device 120 can be straightened toward
the center of the opening portion 105.
[0065] The shape of the upper cover 160 includes, for example, a plate member installed
in the horizontal direction, similar to Embodiment 6. From the viewpoint of straightening
the flow of air supplied from the ejecting device 120, the surface of the upper cover
160 on the opening portion 105 side is preferably formed in a direction in which the
air supplied from the ejecting device 120 flows.
[Embodiment 8]
[0066] Fig. 11 is a view schematically illustrating a front view of a booth 13 according
to Embodiment 8. In the booth 13 according to Embodiment 8, the wind speeds of the
air (outside airflow 126 and inside airflow 127) supplied from the ejecting device
120 are different between an upper part and a lower part of the booth 10 according
to Embodiment 1. More specifically, in the booth 13 according to Embodiment 8, the
wind speed of an upper air of the air (outside airflow 126 and inside airflow 127)
supplied from the ejecting device 120 is faster than the wind speed of a lower air.
In addition, the other configurations are the same.
[0067] In a case where the temperature of the air supplied from the ejecting device 120
is lower than that of the external space, the air supplied from the ejecting device
120 is heavier than the air of the external space. Therefore, a tendency is observed
that the air supplied from the ejecting device 120 flow downward. For that reason,
there is a concern that outside air is likely to flow in from the upper part of the
opening portion 105. According to the booth 13 according to Embodiment 8, since the
wind speed of the air on an upper side of the opening portion 105 is faster than the
wind speed of the air on a lower side, the inflow of outside air from the upper part
of the opening portion 105 can be suppressed.
[0068] In a case where the wind speed of the air (outside airflow 126 and inside airflow
127) supplied from the ejecting device 120 is changed between the upper part and the
lower part, the air may be set to two-step speeds of high speed and low speed or may
be set to gradually increase the speed upward at a plurality of steps of speeds.
[0069] In addition, the configuration in which the wind speed of the air on the upper side
is made faster than the wind speed of the air on the lower side includes not only
means for increasing the linear velocity of the air on the upper side but also means
for increasing the amount of air on the upper side.
[0070] Here, the wind speed of the air suctioned by the suction device 130 may be a constant
wind speed in the height direction, or the wind speed of the air suctioned on the
upper side may be set to be higher than that on the lower side, similar to the air
supplied from the ejecting device 120.
[0071] Additionally, as a modification example of the booth 13 according to Embodiment 8,
in a case where the air supplied from the ejecting device 120 has a temperature higher
than that of the external space, the wind speed of the air on the lower side may be
set to be faster than the wind speed of the air on the upper side. Since the air supplied
from the ejecting device 120 is lighter than the air in the external space, a tendency
to flow upward is observed. Thus, in this case, the inflow of outside air can be suppressed
by setting the wind speed of the air on the lower side to be faster than the wind
speed of the air on the upper side.
[Embodiment 9]
[0072] Fig. 12 is a view schematically illustrating a front view of a booth 22 according
to Embodiment 9. In the booth 22 according to Embodiment 9, the wind speeds of the
air (outside airflow 226 and inside airflow 227) supplied from two ejecting devices
120 are different between an upper part and a lower part of the booth 20 according
to Embodiment 2. More specifically, in the booth 22 according to Embodiment 9, the
wind speed of an upper air of the air (outside airflow 226 and inside airflow 227)
supplied from the ejecting device 120 is faster than the wind speed of a lower air.
In addition, the other configurations are the same.
[0073] Additionally, since the setting of the wind speed of the air supplied from the ejecting
device 120 is the same as that of Embodiment 8 the setting is omitted.
[Simulation results]
[0074] Figs. 13A to 15C are views illustrating the results of a simulation regarding the
temperature distribution of the booth of the present invention. As for the conditions
of the simulation, the temperature of the internal space was set to 23°C and the temperature
of the external space was set to 28°C, and the operational effects of the respective
components were verified with the goal of satisfying ± 0.1°C as the temperature control
of the internal space. In addition, in a case where the ejecting device was installed
only on one side in Embodiment 1 and Embodiment 6 of Figs. 13A and 13B, the wind speeds
of the outside airflow and the inside airflow were set to 2 m/s, respectively. Additionally,
in a case where the ejecting devices were installed on both sides in Embodiment 2
of Figs. 14A to 14C and Embodiment 7 of Figs. 15A to 15C, the wind speeds of the outside
airflow and the inside airflow were set to 2 m/s in any of the ejecting devices. As
for the results of each simulation, the left figure illustrates the temperature distribution
of a vertical cross-section of the opening portion at the position of the inside ejection
port, and the right figure illustrates the temperature distribution of the vertical
cross-section of the opening portion at the position of the outside ejection port.
[0075] Fig. 13A illustrates the temperature distribution using the booth of Embodiment 1
and Fig. 13B illustrates the temperature distribution using the booth of Embodiment
7. In both Fig. 13A and Fig. 13B, an excellent temperature distribution was obtained
at the position of the inside ejection port. It is considered that this is because
the inside airflow suppresses the inflow of the outside airflow into the internal
space while the outside airflow blocks the disturbance.
[0076] Additionally, in a case where Figs. 13A and 13B are compared with each other, it
was found that in a case where the upper cover 160 was provided, a better temperature
distribution was obtained. It is considered that this is because the airflow ejected
from the ejecting device 120 is straightened by the suction device 130 along the upper
cover 160 without being dispersed in the upward direction.
[0077] Fig. 14A illustrates the temperature distribution of the opening portion in a case
where the directions (θi1 and θi2, θo1 and θo2) of the airflow are 0° in the booth
of Embodiment 2, Fig. 14B illustrates the temperature distribution of the opening
portion in a case where the directions (θi1 and Θi2, θo1 and θo2) of the airflows
are 15° in the booth of Embodiment 2, and Fig. 14C illustrates the temperature distribution
of the opening portion in a case where the directions (θi1 and Θi2, θo1 and θο2) of
the airflows are 30° in the booth of Embodiment 2.
[0078] Comparing Figs. 14A, 14B, and 14C, it was observed that the temperature distribution
in the booth (not illustrated) gave the best result in the case where the directions
(θi1 and θi2, θo1 and θo2) of the airflows were 15° (Fig. 14B), and next, the excellent
temperature distributions were obtained in order of the case where the directions
of the airflows were 30° (Fig. 14C) and the case where the directions of the airflows
were 0° (Fig. 14A). It is considered that this is because the directions of the airflows
ejected from both sides of the opening portion are directed slightly outward, so that
the airflows are guided to the external space side in a case where the airflows on
both sides collide with each other.
[0079] Fig. 15A illustrates the temperature distribution of the opening portion in a case
where the directions (θi1 and θi2, θo1 and θo2) of the airflow are 0° in the booth
of Embodiment 7, Fig. 15B illustrates the temperature distribution of the opening
portion in a case where the directions (θi1 and θi2, θo1 and θo2) of the airflows
are 15° in the booth of Embodiment 7, and Fig. 15C illustrates the temperature distribution
of the opening portion in a case where the directions (θi1 and θi2, θo1 and θo2) of
the airflows are 30° in the booth of Embodiment 7.
[0080] Comparing Figs. 15A, 15B, and 15C, similar to the booth of Embodiment 2, it was observed
that the temperature distribution in the booth (not illustrated) gave the best result
in the case where the directions (θi1 and θi2, θo1 and θo2) of the airflows were 15°
(Fig. 15A), and next, the excellent temperature distributions were obtained in order
of the case where the directions of the airflows were 30° (Fig. 15B) and the case
where the directions of the airflows were 0° (Fig. 15C).
[0081] In addition, comparing Figs. 15A and 14B, Fig. 15A had a better temperature distribution.
That is, it can be said that the upper cover covering the upper part of the opening
portion is particularly excellent in the effect of maintaining the temperature of
the internal space.

a factory may be the internal space S. Additionally, the booth may not be provided
with an air conditioning device, and by applying each embodiment, it is possible to
suitably prevent the mixing of dust.
